Background: Multidomain dementia-prevention interventions delivered via apps have the potential to reach large populations. However, existing trials have tended to recruit more socioeconomically advantaged participants, raising concerns that the resulting interventions may be less usable or engaging for some groups of older adults, particularly those from minority ethnic, lower educational, or lower socioeconomic backgrounds, who are at higher risk of dementia. ENHANCE was designed to address this by prioritising accessibility and engagement across diverse user groups, with the goal of developing an intervention that is acceptable and effective for all. Objective: This study evaluated the usability and user experience of the ENHANCE prototype during a one-week at-home supported-use test and explored factors influencing engagement among older adults. Methods: We purposively recruited 10 adults aged 60–80 years without dementia for a one-week mixed-methods usability evaluation, consistent with recommended sample sizes for identifying major usability issues. Participants were recruited through community settings including groups underrepresented in dementia-prevention trials and had at least one of 10 pre-specified dementia risk factors. They attended a face-to-face onboarding session with a coach, used the ENHANCE app at home for seven days with ongoing coach support, and completed a post-test interview and an eight-item satisfaction survey. We analysed quantitative data, including app usage metrics against prespecified minimum use targets and satisfaction survey responses descriptively, alongside reflexive thematic analysis of qualitative data from onboarding sessions, post-test interviews, coaching calls, and in-app message. Results: Participants represented a wide range of neighbourhood deprivation (Index of Multiple Deprivation deciles 1–8), with four from ethnic minority backgrounds. All met prespecified minimum-use targets (watching a module video, completing a check-in, and playing assigned games at least once), and many demonstrated additional voluntary engagement (e.g., repeated gameplay, video rewatching, and use of messaging or phone support). Survey responses indicated high satisfaction, perceived usefulness, and ease of use; 90% intended to continue using the app and 80% would recommend it to peers. Qualitative analysis identified engagement facilitators, including rewarding game design supporting trial-and-error learning, familiar interfaces and game conventions, appropriately challenging gameplay, consistent virtual rewards, trusted expert information combined with peer stories, and coach support with hands-on practice and follow-up. Barriers included unclear visual cues, limited accommodation of motor or sensory impairments, and visual discomfort in some games, highlighting targets for refinement. Conclusions: Older adults recruited via community settings serving underrepresented groups found the ENHANCE prototype usable, acceptable, and engaging over one week of supported at-home use. Participants highlighted human coaching, inclusive design, and integration of expert and peer narratives as key drivers of engagement. These findings support further feasibility testing to examine longer term engagement and provide design insights to inform development of more inclusive digital health interventions.

Journal Description
Welcome to JMIR's own preprint server. It includes preprints from JMIR authors who have opted-in to preprinting their article when submitting, and preprints from non-JMIR authors.
JMIR Preprints is a preprint server and "manuscript marketplace" with manuscripts that are intended for community review. Great manuscripts may be snatched up by participating journals which will make offers for publication.There are two pathways for manuscripts to appear here: 1) a submission to a JMIR or partner journal, where the author has checked the "open peer-review" checkbox, 2) Direct submissions to the preprint server.
For the latter, there is no editor assigning peer-reviewers, so authors are encouraged to nominate as many reviewers as possible, and set the setting to "open peer-review". Nominated peer-reviewers should be arms-length. It will also help to tweet about your submission or posting it on your homepage.
For pathway 2, once a sufficient number of reviews has been received (and they are reasonably positive), the manuscript and peer-review reports may be transferred to a partner journal (e.g. JMIR, i-JMR, JMIR Res Protoc, or other journals from participating publishers), whose editor may offer formal publication if the peer-review reports are addressed. The submission fee for that partner journal (if any) will be waived, and transfer of the peer-review reports may mean that the paper does not have to be re-reviewed. Authors will receive a notification when the manuscript has enough reviewers, and at that time can decide if they want to pursue publication in a partner journal.
For pathway 2, if authors do not wish to have the preprint considered in a partner journal (or a specific journal), this should be noted in the cover letter. Also, note if you want to have the paper only considered/forwarded to specific journals, e.g. JMIR, PLOS, PEERJ, BMJ Open, Nature Communications etc), please specify this in the cover letter.
Manuscripts can be in any format. However, an abstract is required in all cases. We highly recommend to have the references in JMIR format (include a PMID) as then our system will automatically assign reviewers based on the references.

Background: Traditional anatomy teaching relies on cadaveric dissection and 2D resources, which often require in-person attendance and may limit spatial understanding. Virtual reality (VR) provides an immersive, remote alternative that supports three-dimensional visualization from home. Objective: This randomized controlled trial compares remote synchronized VR with passive animation for the teaching of tracheostomy anatomy. Methods: Participants attended an online lecture delivered by a consultant surgeon before being randomized to receive either a VR demonstration within the Medverse platform or a 10-minute animation. Confidence and anatomical understanding were assessed using 5-point Likert scales, and knowledge was measured with a 10-item multiple-choice test administered pre- and post-intervention. Within-group changes were analyzed using the Wilcoxon signed-rank test and between-group differences using the Mann–Whitney U test. Results: Twenty-four medical students from 11 UK and Irish medical schools participated; 92% reported no prior tracheostomy anatomy teaching. Anatomical confidence improved significantly in the VR group compared with animation (mean change 1.58 ± 1.00 vs 0.50 ± 0.80, P = 0.012). Knowledge scores improved significantly in both groups (VR: +1.75 ± 1.54, P = 0.007; Animation: +2.83 ± 1.70, P = 0.003), with no significant post-intervention difference between groups (p > 0.46). VR participants reported significantly superior spatial understanding across all measured domains (all P ≤ 0.009). Conclusions: Remote VR teaching is feasible, engaging, and enhances spatial understanding relative to animation. While knowledge gains were comparable between modalities, VR improved learner confidence and perceived three-dimensional comprehension. VR may represent a scalable adjunct or alternative to traditional anatomy teaching.

Background: Artificial Intelligence (AI) is increasingly integrated into healthcare, with potential to enhance disease diagnosis, treatment, and patient outcomes. However, successful adoption relies on healthcare providers’ preparedness and trust. Objective: To evaluate French healthcare professionals’ and students’ use, concerns, and perceptions of AI, and to assess their interest in AI-related training. Methods: We conducted a cross-sectional national survey distributed via PulseLife between December 2023 and March 2025. The 12-item questionnaire assessed demographics, AI usage, confidence, perceived benefits, concerns, and training needs. Reliability and validity of the instrument were assessed using Cronbach α, exploratory and confirmatory factor analysis. Descriptive statistics and chi-squared test were performed using R (version 4.3.1). Results: A total of 1625 healthcare respondents participated, including 1212 professionals (52.9% physicians, 19.1% nurses) and 413 students. Only 6.6% reported prior AI training, while 78.3% expressed interest in receiving training. Physicians showed the highest confidence in AI (P = .003). Main concerns included algorithmic bias (48.2%), data transparency (40.9%), and deterioration of the doctor–patient relationship (38.6%). Anticipated benefits included improved diagnosis (47.6%), time saving (42.1%), reduced medical errors (39%). Conclusions: French healthcare providers and students remain insufficiently trained in AI, despite strong interest in acquiring such skills. Structured AI training programs and transparent regulatory frameworks are urgently needed to facilitate responsible adoption of AI in healthcare.

Health digital twins, computational models that integrate longitudinal data, simulation, and forecasting, are increasingly proposed as tools for chronic care management. Most current implementations, however, are expert-oriented, prioritizing technical optimization and clinical prediction while offering limited support for patient understanding, engagement, or participation. This orientation is particularly misaligned with chronic care, which unfolds largely outside clinical settings and depends on patients’ daily decisions, social context, and sustained engagement over time.
In this Viewpoint, we argue for reframing digital twins as participatory systems that support shared sensemaking among patients, caregivers, and clinicians, rather than functioning solely as directive, expert-facing tools. We propose a conceptual framework that positions participatory digital twins as boundary objects capable of bridging computational models, clinical reasoning, and lived experience. Within this framework, generative artificial intelligence serves as a translation and interaction layer, enabling plain-language dialogue, exploration of uncertainty, and “what-if” reasoning that allows users to interpret model outputs in relation to their own contexts, goals, and constraints.
We outline key design principles for participatory digital twins, including visible uncertainty, negotiated rather than prescriptive care, mechanisms for incorporating patient context and social drivers of health, and governance structures that support accountability and recourse. By shifting the focus from optimization alone to understanding, interaction, and trust, participatory digital twins offer a pathway toward more equitable, human-centered, and sustainable models of AI-enabled chronic care.

Background: Stroke is a leading cause of long-term disability and often transfers substantial care responsibilities to family and informal caregivers. These demands contribute to multidimensional caregiver burden and reduced quality of life (QoL), including psychological distress, social limitations, and financial strain. Digital health interventions—such as mobile applications, messaging-based education, telehealth, and web-based platforms—have the potential to extend caregiver support beyond conventional face-to-face services; however, evidence regarding their impact on caregiver QoL remains heterogeneous. Objective: This scoping review aimed to map and characterize digital health interventions used in stroke caregiving and to summarize their associations with caregiver QoL–related outcomes, including caregiver burden, psychological well-being, empowerment or capability, usability, and access. Methods: A scoping review was conducted in accordance with Joanna Briggs Institute (JBI) guidance and reported following PRISMA-ScR. Searches were performed in PubMed, Scopus, Web of Science, CINAHL, and Google Scholar for English-language studies published between 2019 and 2025. Two reviewers independently screened studies and extracted data using a standardized charting form. Evidence was mapped descriptively by intervention type, delivery characteristics, study design maturity, and caregiver outcome domains. Results: From 676 identified records, 20 studies met the inclusion criteria. Digital interventions were primarily delivered through mobile applications, WhatsApp-based education, telehealth services, or web-based learning platforms. Direct caregiver-focused studies commonly assessed caregiver burden, psychological distress, and caregiving capability, while system-integrated mHealth programs mainly reported patient outcomes with indirect relevance to caregivers. Overall, digital education and follow-up support were associated with reduced caregiver burden and improved caregiver capability and emotional well-being, although outcome measures and follow-up durations varied. Usability, digital literacy, affordability, and connectivity were recurrent barriers. Conclusions: Digital health interventions show promise in improving caregiver QoL in stroke care, particularly through structured education and ongoing support. Future studies should emphasize rigorous caregiver-centered trials, standardized QoL measures, longer follow-up, and inclusive designs addressing digital equity.

Background: Digital technologies have the potential to support proactive identification of early signs of medicine-related harms, including changes in sleep, physical activity, and cognition. The use of a centralised digital platform to support pharmacists in monitoring longitudinal health data and detecting medicine-related harms in this setting has not been evaluated. Objective: To develop and assess the feasibility of a digitally enabled pharmacist service to monitor signs and symptoms of medicine-related harms in residential aged care. Methods: The study was conducted in two phases. In Phase I, the establishment phase, health and medication data from participants’ records were exported into the TeleClinical Care (TCC-ADEPT) digital platform. Phase II comprised a 12-week feasibility study with assessments conducted at baseline, 4 weeks, 8 weeks, and 12 weeks. During this phase, the on-site residential aged care pharmacist monitored all participants using the centralised TCC-ADEPT platform.
The digital technology intervention included collection of digital biomarkers to supplement information from patient care record and medication chart with subsequent display as longitudinal visualisations of change in residents’ health and medicine use using a cloud-based monitoring platform; TeleClinical Care. The aged care pharmacist monitored residents’ clinical, medicine, sleep, and physical activity data to identify signs and symptoms of medicine-related harms using the centralised platform and notified the residents’ general practitioners when necessary.
The RE-AIM framework was used to evaluate the feasibility of the digitally informed pharmacist service. Assessments included service reach, changes in resident symptom scores as measured by the Edmonton Symptom Assessment Scale, medicine use, number of adverse events, cognitive scores as measured by the Montreal Cognitive Assessment, sleep and physical activity as measured by sleep sensor and accelerometer, number and types of pharmacist recommendations to general practitioners (GPs), and qualitative interviews. Results: Twenty-nine participants were enrolled in the study, with 27 completing the 12-week assessments. The average age was 86 years old, and 65% were female. There was a significant decrease in total numbers of adverse events at 12-weeks compared to baseline (45 at baseline, 27 at 12-weeks; p=0.006). There were no significant differences in changes in symptom scores, medicine use, cognitive scores, sleep, and physical activity. Overall, the pharmacist made 25 recommendations to the participants’ GP; with half (n=13, 52%) being implemented.
Five residents, one family member, the on-site pharmacist, three staff members, and two members of senior management were interviewed to understand their views of the pharmacist service as well as facilitators and barriers to its delivery. Overall, participants reported positive views of the service, and senior management indicated an intention to continue using the service. Conclusions: Our findings suggest that the digitally informed pharmacist service is feasible and has the potential to reduce adverse events due to medicines within the aged care setting.

Background: Early detection of adolescent idiopathic scoliosis (AIS) is critical for timely intervention and optimal clinical outcomes. Conventional radiography, the current reference standard, is poorly suited for large-scale screening because of cumulative ionizing radiation exposure and concerns related to privacy and patient acceptability. Objective: This study aimed to evaluate the diagnostic accuracy of a millimeter-wave imaging system for scoliosis screening, using radiographic Cobb angle measurements as the reference standard. Methods: In this prospective diagnostic accuracy study, 132 consecutive pediatric outpatients (aged 6-23 years) with suspected scoliosis underwent a 2-second millimeter-wave scan of the back without removing clothing, followed by standard standing full-spine radiography. Scoliosis was defined as a Cobb angle of ≥10°. Millimeter-wave images were evaluated for established morphological indicators of spinal asymmetry, including shoulder height asymmetry, trunk lateral shift, waistline contour asymmetry, and lower limb height discrepancy. Diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated in accordance with STARD reporting guidelines. Participants older than 18 years were included to reflect real-world outpatient screening practice. Results: Radiographic assessment identified scoliosis in 98 of 132 participants (74.2%). Millimeter-wave imaging achieved an overall accuracy of 86.4% (95% CI 76.5-94.7), with a sensitivity of 85.7% (95% CI 75.1-96.5) and a specificity of 88.2% (95% CI 70.7-97.6). All scans were completed within 2 seconds and maintained full patient privacy. Conclusions: Millimeter-wave imaging is a feasible, rapid, and nonionizing modality for scoliosis screening. Its high sensitivity supports its use as a first-line screening tool in school and outpatient settings, enabling targeted referral for confirmatory radiography while adhering to the ALARA principle.

Background: Despite the high accuracy of machine learning models in predicting diabetes, clinical adoption remains limited due to the "black-box" nature of advanced algorithms. In regional healthcare contexts like Ethiopia, fostering clinician trust is essential for the successful implementation of AI-driven tools. Objective: This study aims to develop a trustworthy Clinical Decision Support System (CDSS) for diabetes prediction by operationalizing the Asan et al. (2020) trust framework focusing on Ability, Integrity, and Benevolence through the integration of Explainable AI (XAI) techniques. Methods: A multi-national dataset of clinical biomarkers was utilized. To ensure model Ability, we employed a robust preprocessing pipeline including Standardization and SMOTE for class balancing. Five architectures were compared: Logistic Regression, Random Forest (RF), Gradient Boosting, XGBoost, and LightGBM. To establish Integrity, this research utilized SHAP (SHapley Additive exPlanations) for global and local transparency. To demonstrate Benevolence, this research applied Diverse Counterfactual Explanations (DiCE) based on Miller’s (2017) theory of contrastive explanation. Results: The Random Forest model emerged as the superior architecture, achieving high Macro-averaged AUC and F1-scores. SHAP global analysis validated model integrity by identifying HbA1c, Age, and BMI as the primary diagnostic drivers, aligning with international clinical guidelines. DiCE generated patient-specific "what-if" scenarios, providing clinicians with actionable targets for lifestyle intervention. Preliminary evaluation suggests that providing both "why" (SHAP) and "how to change" (DiCE) explanations significantly enhances perceived clinician trust compared to standard accuracy-only outputs.The final model was deployed as an interactive Streamlit application 1. Conclusions: Integrating SHAP and Counterfactual analysis transforms predictive AI into a prescriptive clinical partner. By providing actionable insights that clinicians can relate to their medical knowledge, this integration initiates a culture of XAI examination for clinicians, paving the way for more transparent and patient-centered digital health interventions.

Background: Frailty is a multidimensional clinical syndrome characterized by diminished physiologic reserve and increased vulnerability to stressors, thus putting older adults at higher risk of adverse outcomes (e.g., falls, mental and physical disability, hospitalization, mortality) in response to even minor stress events. Frailty can be reversed or at least attenuated if detected early, yet early identification remains challenging in primary care due to time- and resource-intensive assessment methods. Artificial intelligence (AI) offers promise in automating frailty identification at the point of care. Natural Language Processing (NLP) is particularly valuable for extracting frailty indicators from rich text data stored in electronic health records, but its limited interpretability has prompted growing interest in augmenting the NLP processes with the use of explainable AI (XAI) techniques. Although NLP and XAI methods have been applied for chronic disease identification, their use for frailty identification has not yet been systematically examined. Objective: This scoping review aimed to synthesize current evidence on the use of NLP and XAI methods for automating frailty identification in older adults. Methods: Peer-reviewed studies published in English between January 2015 and November 2025 were eligible if they applied AI, NLP, or XAI methods to identify frailty in adults aged ≥50 years using real-world health data from OECD or OECD-partner countries. Searches were performed in PubMed and Google Scholar and supplemented by screening bibliographies of identified studies. Data were extracted using a standardized form that captured study characteristics, sample size, data sources, and specific aspects of the AI models, and NLP and XAI methods used. Results: We identified 24 studies that satisfied the eligibility criteria. While all studies used AI approaches to identify frailty, only six used neural network-based models. Logistic regression was the most frequently used AI method (n=14), and only one study employed Bidirectional Encoder Representations from Transformers (BERT). Seven studies relied on both structured and unstructured data, two relied exclusively on structured data only, and the rest relied exclusively on unstructured data. Seven studies used NLP methods, seven used XAI methods, and only one integrated both. Only two studies reported deploying their models in real clinical settings. Conclusions: AI-based approaches show promise for automating frailty identification, yet current applications remain limited by reliance on traditional machine learning models, underuse of NLP and XAI methods, and very little real-world deployment. Future work should focus on developing explainable NLP models, facilitating access to large volumes of unstructured data, and developing standardized frameworks for the systematic evaluation of NLP and XAI methods. Coordinated efforts across clinical, technical, and regulatory domains are essential to develop scalable, transparent, and clinically meaningful AI systems for frailty identification.

Background: Anticoagulated patients with atrial fibrillation (AF) face significant bleeding risks, which current risk scores inadequately predict. Pulse pressure (PP), a marker of arterial stiffness, may offer additional prognostic value. Objective: This study aimed to evaluate whether elevated PP independently predicts major bleeding events. Methods: We conducted a retrospective cohort study using electronic health records from 4,935 AF patients on oral anticoagulation (2010–2019) in the REACHnet network. PP was calculated from outpatient blood pressure readings and analyzed in tertiles and as a continuous variable. Kaplan-Meier curve and log-rank test were conducted to assess the association between PP and clinical outcomes. Cox regression models further adjusted for demographics, comorbidities, systolic blood pressure, medications, and the ORBIT bleeding score. Results: Over a median 5-year follow-up, 677 patients (13.7%) experienced major bleeding. GI bleeding was significantly more frequent in the highest PP tertile (p = 0.007), while intracranial and other bleeding types showed no significant differences. Each 10 mmHg increase in PP was associated with a 15% higher risk of GI bleeding (HR: 1.014; p = 0.042), and this association remained significant after adjusting for systolic blood pressure and the ORBIT score (OR: 1.013 per mmHg; p = 0.028). PP was not significantly associated with intracranial, other, or overall bleeding. Conclusions: Pulse pressure independently predicts gastrointestinal bleeding in anticoagulated AF patients, even after accounting for traditional bleeding risk factors. These findings support the inclusion of PP in future risk stratification models and clinical monitoring strategies. Clinical Trial: N/A

Background: Mobile applications (apps) have emerged as a convenient and accessible solution to support weight management. More than 28,000 apps related to weight loss are available across various platforms. However, there is a lack of understanding of the most effective approach to evaluate the quality of these apps. Existing studies have focused only on popular apps or specific user groups. Objective: To identify the approaches employed to assess the quality of weight loss apps and to determine which app features are considered important for enhancing their effectiveness. Methods: This systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A comprehensive literature search was carried out across four databases: PubMed, Embase, Medline, and Web of Science. As inclusion criteria, studies were eligible if they specifically assessed weight-loss apps among healthy adult users (aged ≥18 years) and were published between January 1st 2019, and June 30th 2024. Studies were excluded if they focused on non-digital interventions, were not in English, involved clinical, military, or athletic populations, or were review articles, meta-analyses, conference abstracts, or reports. Search terms were derived from the concepts of quality, weight loss, and mobile applications. Data extraction focused on the approaches used to evaluate app quality. Results: Eleven studies met the inclusion criteria, evaluating a total of 46 distinct weight loss apps. Seven generic app evaluation approaches and two supporting frameworks were identified, with the most frequently used being the Mobile App Rating Scale (MARS) (n=39 apps), Evidence-based Strategies (EBS) Assessment (n=25 apps), and Six Sigma (n=25 apps). Only two approaches, MARS and the System Usability Score (SUS), have been validated to evaluate mobile apps. A total of 8 feature categories were identified as present in the apps across the studies. The most frequently observed were nutrition education (5), self-monitoring and tracking (5), exercise content & tools (5), behavioural support (4), social features (4), coaching and feedback (3), planning and goal setting (3), and technical functionality (2). Nine features were also recommended by the study authors to enhance app effectiveness through behaviour change. These features are progress reports (4), self-monitoring (2), reminders (3), gamification (2), and expert monitoring (1), comprehensive nutrition databases (3), food entry options (2), barcode scanning of calorie content (2), and affordability (2). Only the initial five are associated with behaviour change elements as per the BCT Taxonomy framework. Conclusions: A range of approaches are currently employed to evaluate the quality of weight loss apps. This review identified seven commonly used evaluation approaches and two supporting frameworks, with MARS being the most frequently applied. Additionally, this study identifies a set of common and key features that should be prioritised in the development of weight loss apps for adults living with obesity to potentially enhance their overall effectiveness.

Background: Bipolar disorder (BD) is a complex and heterogeneous psychiatric condition, characterized by fluctuating clinical courses that affect approximately 1-2% of the global population. Despite pharmacological advances, treatment response varies significantly among patients, making the identification of individualized treatment strategies a major challenge. Recently, artificial intelligence (AI) has emerged as a powerful approach in precision psychiatry to identify subtle patterns in complex data and inform personalized clinical decisions. Objective: Provide a structured synthesis of current evidence on AI-supported treatment optimization in BD spectrum. Methods: This systematic review was conducted in accordance with the PRISMA 2020 guidelines. Four databases (PubMed, Web of Science, Scopus, and EMBASE) were searched for original studies published after 2015 on the application of AI in the treatment of BD in adult patients. The methodological quality, risk of bias, and clinical applicability of the predictive models were assessed using the PROBAST+AI tool. Results: A total of 35 studies were included, divided into three main categories. Treatment response prediction, focused primarily on lithium response, with accuracies up to 100% in multimodal models. Relapse risk prediction, where models demonstrated feasibility in predicting relapses and rehospitalizations with AUCs between 65% and 85%. Patient stratification, used to identify clinical subgroups and pharmacological profiles, with excellent predictive capabilities (AUCs up to 99%). However, the PROBAST+AI assessment revealed a high risk of bias in most studies, primarily due to data analysis limitations, small sample sizes, and lack of external validation. Conclusions: The adoption of AI tools in BD serves as a driver for therapeutic optimization, although current AI tools in BD should still be considered exploratory rather than ready for clinical use. Effective implementation in real-world clinical scenarios requires more robust, transparent, and externally validated models to ensure reliability and generalizability.

Background: Background: Lateral neck lymph node metastasis (LLNM) is a major determinant of recurrence risk and surgical strategy in papillary thyroid carcinoma (PTC). However, accurate preoperative identification of LLNM remains challenging, as conventional imaging assessment is limited by operator dependency and variable diagnostic performance. Although several predictive models have been proposed, many suffer from limited generalizability or poor interpretability, hindering their integration into clinical decision-making. Objective: Objective: Preoperative accurate prediction of LLNM in PTC remains challenging, and existing models have limitations such as poor interpretability or restricted applicability. This study aimed to develop and validate an interpretable machine learning (ML) model based on routine clinical and ultrasound data to predict LLNM risk in PTC patients. Methods: Methods: A retrospective cohort study enrolled 816 PTC patients (June 2022-May 2024), randomly split into training (n=571) and internal validation (n=245) sets at a 7:3 ratio, with an independent external validation cohort of 178 patients (June 2024-May 2025). Clinical, laboratory, and routine ultrasound data were collected. Feature selection employed a three-step approach: (1) univariate and multivariate logistic regression (LR) analysis, (2) Boruta-SHAP algorithm for importance ranking, and (3) clinical expert validation to ensure clinical relevance. Nine ML models were developed, with hyperparameter tuning via grid search and 10-fold cross-validation. Model performance was evaluated using metrics such as area under the receiver operating characteristic curve (ROC), sensitivity, specificity, and F1-score. The SHapley Additive exPlanations (SHAP) method was used for model interpretation. Results: Results: Eight independent risk factors were identified: gender, multifocality, age, tumor diameter, tumor location, capsular invasion, central lymph node metastasis, and uneven lateral cervical lymph node hilum echo. The Gradient Boosting Machine (GBM) model demonstrated optimal performance with an AUC of 0.905 (95% CI: 0.868-0.942), sensitivity of 0.831, specificity of 0.840, and F1-score of 0.764 in internal validation. External validation confirmed robust generalizability (AUC: 0.887, 95% CI: 0.840-0.934).SHAP analysis revealed that tumor size, gender, lateral cervical lymph node echo, central lymph node metastasis, and capsular invasion were the top five contributors to high LLNM risk, and provided individualized risk interpretation. Conclusions: Conclusion: This interpretable GBM model, based on routinely accessible clinical and ultrasound data, enables accurate preoperative LLNM risk stratification, supporting personalized decisions on the extent of lymph node dissection and potentially reducing unnecessary prophylactic surgery while ensuring adequate treatment for high-risk patients.

Background: Depression is prevalent among adolescents and young adults and often requires aftercare following inpatient treatment. Although effective outpatient aftercare exists, many patients face difficulties in maintaining treatment gains and remain without professional support after being discharged. Digital mental health interventions hold promise for bridging this care gap; however, evidence of their effectiveness is limited. Objective: This protocol outlines a study evaluating the effectiveness, cost-effectiveness, and implementation of a chatbot-assisted smartphone intervention (iCAN) designed to support youth following inpatient treatment for depression. Methods: This is a prospective, two-armed, mixed-methods randomized controlled trial. The targeted sample size is n = 368 patients aged 13–25 years with depressive disorders who were receiving inpatient treatment and, additionally, n = 18 healthcare providers. Participants in the intervention group received care as usual plus an e-coach-guided intervention for 90 days, whereas the control group received care as usual only. Assessments were conducted at baseline and 6 weeks, 3 months, and 6 months after randomization. The primary outcome is clinician-rated severity of depression symptoms. Secondary outcomes include remission rates, general psychopathology, quality of life, uptake of aftercare services, cost-effectiveness, mechanisms of action, as well as acceptability, and usability. Outcome evaluation will use linear mixed models based on the intention-to-treat principle, and process evaluation will be conducted via content analysis. Results: We enrolled n = 228 patients from 31 hospitals across Germany between November 2023 and December 2024. Data collection (6 months follow-up) was completed June 2025. Data analysis is currently in progress, with the first results expected to be published by the end of 2026. Conclusions: This study will provide evidence for the effectiveness and cost-effectiveness of a guided digital mental health intervention for post-discharge aftercare of youth treated for depression in an inpatient setting. It will offer insights into the implementation of the intervention in routine care. If proven effective, iCAN may serve as a blueprint for remote aftercare for young people with depression. Clinical Trial: This trial is registered in the German register for clinical trials (DRKS-ID: DRKS00032966)

Background: Mild cognitive impairment (MCI) is recognized as a critical stage for dementia prevention. Physical activity is an important intervention to prevent cognitive decline, but challenges still remain in improving or maintaining cognitive function in older adults with MCI through increased physical activity. Personalized mobile health (mHealth) promotion strategies based on the Behaviour Change Wheel (BCW) hold promise for enhancing physical activity levels in this population. Objective: This study aims to evaluate the feasibility and preliminary effectiveness of a personalized mobile application (App) named ActiveAide, developed based on the BCW framework, for promoting physical activity among older adults with MCI. Methods: This feasibility study employed a single‑arm, pre‑ and post‑test design. 18 participants received an 8‑week personalized intervention via ActiveAide. Feasibility measures included recruitment rate, retention rate, App usage data, App usability evaluation, and user experience with the App. Effectiveness measures encompassed physical activity level, physical fitness, physical activity self‑efficacy, and social support. Quantitative data were analyzed using paired‑sample t‑tests and Wilcoxon signed‑rank tests, while qualitative data underwent content analysis. Results: The study achieved a recruitment rate of 90.9% and a retention rate of 90%. The mean strategy completion rate was 78.5%, with the mean number of App accesses of 71. The mean System Usability Scale (SUS) score was 74.86 ± 8.81, indicating good usability. Qualitative interviews identified three themes: strengths of MotiveAide, limitations of MotiveAide, and suggestions to improve MotiveAide. Post-intervention, statistically significant improvements were observed in participants’ physical activity level (P<0.001), physical activity self-efficacy (P<0.001), VO2max (P<0.001), strength assessment score (P=0.002), and body composition measures including total physical score (P<0.001), fat mass (P=0.001), and body fat percentage (P<0.001). No significant change was found in the level of social support. Conclusions: The personalized mHealth application ActiveAide, developed based on the BCW framework, demonstrated good feasibility and preliminary effectiveness in promoting physical activity among older adults with MCI. Future research could further optimize the application’s features and employ more rigorous designs, such as randomized controlled trials, to validate its long-term efficacy and generalizability.

Health data interoperability is the central hill climb in contemporary digital
health. Hospitals often accumulate data like mismatched spare parts, catalogued
inconsistently, and difficult to re-use across care. The landscape of non-annotated
source systems, legacy data warehouses that lack interoperable data models,
the coexistence of multiple terminologies with divergent scopes, the operational
turbulence of system migrations, and the persistent challenges of metadata catalogues
and versioning set a starting point to a journey in building a semantic layer
that makes data Findable, Accessible, Interoperable, and Reusable (FAIR), and
that remains robust as terminologies evolve. Terminology updates are complex
and their terms, classifications, and regulations continually change. This viewpoint
article gives an exemplary historical overview at a Swiss university hospital,

Background: Delirium superimposed on dementia is associated with poor outcomes yet remains underdetected in home settings. Current detection relies on face-to-face clinical assessment (e.g., the Confusion Assessment Method (CAM) criteria) rarely applied outside hospitals. Objective: This proof-of-concept study developed a theory-driven framework for detecting delirium-consistent anomalous patterns in home-dwelling people with dementia, using passive smart home sensor data. Methods: Individualized anomaly detection algorithms, including Isolation Forest and Long Short-Term Memory (LSTM) models, were applied to identify delirium-related anomalies within each participant. Predictor features consisted of theory-driven digital markers approximating key CAM criteria, including agitation, disrupted sleep–wake cycles, and disorientation (indexed by activity entropy), along with clinically relevant indicators such as physiological instability (early warning scores) and urinary tract infections. Multimodal smart-home sensor data from 17 individuals with dementia were analyzed. Results: Using matched thresholds, Isolation Forest and LSTM models each identified 71 anomalies, with the Isolation Forest detecting a median of 10.2% anomalous days per individual and anomalies typically occurring in short temporal clusters; agreement between methods was 17%. Feature importance analyses indicated that activity entropy, sleep quality, and early warning scores were the most influential features, with stronger inter-feature correlations observed during anomaly versus non-anomaly periods. Conclusions: This study demonstrates technical feasibility of detecting delirium-related anomalies through passive smart home monitoring. While lacking ground truth validation, the approach shows promise for early intervention in community settings. Future validation studies with clinically confirmed delirium labels are essential.

Background: Since 2011, Türkiye has become the primary destination for Syrian refugees. While healthcare is a fundamental human right, public discourse surrounding refugee health services can influence policy and social cohesion. Objective: The objective of our study was to examine 14 years of Turkish health-related discourse on platform X (formerly Twitter) to identify evolving sentiment, stance, and key grievances. Methods: From a dataset of 4.5 million tweets (2009-2022), 116,172 health-related posts were identified. We employed a fine-tuned Turkish BERT-based large language model to perform multi-task classification for sentiment, stance, and health topics. Tweets were categorized into five domains as Provision of Healthcare Services, Financing and Coverage, Human Resources, Public Health and Disease Prevention, and Access to Medications and Pharmaceutical Services. Lift scores and heatmaps were used to analyze the relationship between the keywords and public attitudes. Results: The fine-tuned Turkish BERT model achieved high classification performance with a weighted F1 score of 0.85 for sentiment and 0.8 for stance detection. Public discourse shifted from neutral or positive tones in 2011 to overwhelming negativity over time. By 2021, negative sentiment reached 79.9%, and anti-refugee stance peaked at 78.3%. Prominent topics evolved from Provision of Healthcare Services (47.5% in 2011) to Public Health and Disease Prevention (57.3% in 2021) and Human Resources (34.6% in 2022). High lift scores revealed that anti-refugee stances were strongly associated with keywords such as ‘appointment’, ‘vaccine’, and ‘free’. Conclusions: There is a marked and consistent rise in anti-refugee sentiment within Turkish digital health discourse, often fueled by misinformation and perceived systemic strain. Public health authorities should prioritize evidence-based communication strategies to counter digital polarization and ensure the legibility of health policies for the host population.

Background: Lumbar disc herniation (LDH) is one of the leading causes of low back and leg pain. Although percutaneous endoscopic lumbar discectomy (PELD) is a useful procedure with a minimally invasive surgical procedure, there are patients with persistent pain and functional impairment. Traditional Chinese Medicine (TCM) has a treatment called Tuina, which was found to be effective in conservative management of LDH. The high-quality evidence of its combined use during the perioperative period of PELD is not available. Objective: The main aim of the trial will be to determine the clinical effectiveness and safety of the Zheng’s "Gu cuo feng, jin chu cao"manipulative therapy when used as the adjunctive to percutaneous endoscopic lumbar discectomy (PELD) of single-level LDH. Methods: The study is a protocol of a randomized controlled superiority trial in a multicenter parallel-group trial to be carried out in 4 Chinese hospitals. There will be 220 eligible patients with single-level LDH randomly assigned by means of 1:1 assignment to the experimental group (it will receive Zheng’s Tuina manipulative therapy before and after the PELD) and to the control group (it will receive PELD only). The main outcome is change in the baseline scores of the Oswestry Disability Index (ODI) score in 3 months after surgery. Visual Analogue Scale (VAS) of the pain, SF-12 health survey, and modified Macnab criteria are classed as the secondary outcomes. The outcome assessors and data analysts will not know the group allocation. Results: - Conclusions: The trial will be rigorous in offering evidence concerning the integration of Chinese and Western medicine in the treatment of LDH. This combination methodology might help in achieving functional recovery, better pain management, and creating a new standard of perioperative rehabilitation among this patient group in case it was proven effective.

Background: Mental health disorders (MHDs) represent a growing global challenge and pose a significant risk to public health. Alongside developments in the field of large language models (LLMs), conversational mental health chatbots (CMHBs) have emerged and are increasingly being used by individuals in self-directed and independent ways to provide therapy and therapeutic support. While users’ perspectives on the use of CMHBs have been extensively examined and systematically synthesized, relatively little research has focused on how healthcare professionals (HCPs) perceive these tools. To develop a holistic understanding of the implications of CMHB use – including potential benefits, risks, and implementation barriers – it is essential to consider the perspectives of HCPs, who bring clinical expertise and psychological knowledge to the evaluation of mental health interventions. Accordingly, the objective of this review is to synthesize empirical evidence on HCPs’ perspectives regarding the use of CMHBs and to explore potential convergences and divergences between professional and user perspectives. Objective: This paper presents the protocol for a systematic review that aims to identify, synthesize, and critically appraise evidence on healthcare professionals’ perspectives regarding the use of CMHBs as tools for therapy or therapeutic support for individuals with MHDs, and to examine perceived benefits, barriers, and potential ethical concerns associated with their use. Methods: A systematic review of literature will be conducted in accordance with the PRISMA 2020 guidelines. Peer-reviewed qualitative, quantitative, and mixed-methods studies will be identified through searches of PubMed/MEDLINE, PsycINFO, Embase, CINAHL, Web of Science, and Scopus, with no restrictions on publication date. Study screening will be supported by AI-assisted active learning using ASReview, following the SAFE stopping procedure, with independent quality-assurance screening by a second reviewer. Data will be synthesized narratively, and methodological quality will be appraised using the Critical Appraisal Skills Programme (CASP) checklist. Results: The database search for this review was performed end of November 2025. The initial Title/abstract screening started in January 2026 and is currently underway. Data extraction is expected to be completed by April, and the final results are expected to be published by August 2026. Conclusions: In light of the rapid emergence of AI-driven chatbots in mental health care, this systematic review will synthesize current empirical evidence to address the urgent need to understand HCPs’ perspectives on the use of CMHBs. Specifically, it will examine how HCPs perceive CMHBs when used to simulate therapeutic interactions, as adjunctive support to conventional therapy, or as potential substitutes for specific therapeutic functions. By identifying perceived benefits, barriers, and ethical concerns, this review aims to contribute to a more comprehensive understanding of the implementation and broader implications of CMHBs in mental health care.

Background: Poor sleep quality is increasingly recognized as a contributor to cardiovascular health and stroke risk. Individuals with diabetes, hypertension, obesity, and heart disease are particularly vulnerable, yet the specific influence of sleep characteristics on this high-risk group remains insufficiently understood. Most previous studies have focused on either sleep duration or insomnia alone, with limited evidence integrating multiple sleep dimensions in adults at elevated risk of stroke, particularly in low- and middle-income settings. Objective: This study aimed to examine multidimensional sleep characteristics and their associations with demographic, behavioral, and cardiometabolic risk factors among adults at high risk of stroke, as well as to identify discrepancies between subjective sleep perception and objective sleep indicators. Methods: This cross-sectional study examined sleep characteristics 303 adults at high risk of stroke with established stroke risk factors. Measures included subjective sleep quality, sleep duration, efficiency, disturbances, use of sleep medication, and daytime dysfunction. Associations with demographic factors, lifestyle behaviors, and comorbidities were analyzed using descriptive statistics and chi-square tests. This study explored multidimensional sleep profiles in relation to cardiometabolic and behavioral risk factors. Results: Among 303 adults at high risk of stroke, 65.7% (n = 199) had poor sleep quality. Objective sleep impairment was common, with over half exhibiting low sleep efficiency (<65%) and 26.4% (n = 80) reporting sleep duration <5 hours. Poor sleep quality was significantly associated with cardiometabolic comorbidities, male sex, smoking, irregular sleep patterns, and family history of cardiovascular disease (all p < 0.001), with effect estimates supported by Confidence Intervals (95% CI). Conclusions: Sleep disturbances are common among individuals at elevated stroke risk and are shaped by demographic, behavioral, and clinical factors. Although most participants perceived their sleep as adequate, objective indicators revealed marked impairment in sleep duration and efficiency Poor sleep quality is closely associated with cardiometabolic comorbidity and may contribute to increased cerebrovascular vulnerability. Routine sleep assessment, early identification of sleep disorders, and targeted interventions—such as sleep hygiene education and screening for obstructive sleep apnea—are essential for stroke prevention. Further longitudinal research is needed to clarify causal pathways and assess the effectiveness of sleep-focused prevention strategies. Longitudinal studies are warranted to clarify causal pathways and to evaluate the impact of sleep-focused interventions on stroke risk in high-risk populations.

Background: Non-medical health factors (NMHF), including education, income, housing, transportation, and neighborhood infrastructure, are crucial to understanding health outcomes and health equity. However, integration of these factors into research and teaching has been challenged by fragmented data sources, heterogeneous data schemas, and inconsistent geographic units. Objective: To design and evaluate a cloud-native, geospatially standardized NMHF data infrastructure that supports end-to-end data acquisition, harmonization, analytics, and visualization for research and education. Methods: We implemented a serverless architecture on Google Cloud Platform, centered on BigQuery for scalable storage and geospatial analytics, while incorporating an improved Extract–Transform–Load (ETL) pipeline for data collection and storage. This cloud-native architecture also integrated Tableau for live interactive dashboards. Reproducible SQL pipelines standardize schemas and harmonize geographies via population-weighted crosswalks between ZIP Code Tabulation Areas (ZCTAs), census tracts, counties, and states. Users access the platform through parameterized SQL queries, Python notebooks, or optional serverless APIs. We evaluated the resulting data coverage, query performance, user adoption, and educational utility of the platform. Results: The platform harmonized data for over 40 NMHF databases across deprivation, vulnerability, opportunity, instability, demographics, and outcomes from widely used public sources at the census tract and ZCTA levels. Over 50 users, including students participating in courses, capstone projects, and workshops, actively engaged with the platform’s notebooks and dashboards. The publicly accessible dashboards accrued over 1,000 unique views. The platform demonstrated support for exploratory analyses linking NMHF indicators with health outcomes, illustrating its value for hypothesis generation and geospatial storytelling. Conclusions: This geospatially standardized, education-oriented NMHF infrastructure minimizes operational friction and shortens time-to-insight for students and researchers. It provides a pragmatic foundation for future efforts in clinical integration of social risk data, scalable federated analytics, and fairness-aware health modeling.

Background: Health systems increasingly deploy large language models (LLMs) to draft patient-facing messages, including patient portal replies and follow-up communications. While these tools may improve efficiency, safety failures often arise not from obvious factual errors but from how content is framed—diagnostic language that exceeds clinical scope, false certainty that minimizes legitimate concerns, or fabricated evidence presented as authoritative. These language-level risks remain poorly characterized and are not routinely addressed within clinical governance workflows. Objective: This study aimed to estimate the prevalence and types of language-level safety risks in AI-generated patient-facing messages and to assess the feasibility of a structured, clinician-led governance approach for identifying and acting on these risks prior to message delivery. Methods: We conducted a single-reviewer simulation feasibility study evaluating 200 AI-generated patient-facing messages representative of common patient portal and follow-up communication scenarios. Messages were generated using GPT-4 (OpenAI) and evaluated using the SAFE-AI Message Guard framework, a clinician-informed operational governance model for identifying language-level safety risks across four domains: (1) clinical scope violations involving non-delegable diagnostic determinations, (2) overconfidence or false reassurance through absolutist language, (3) hallucinated specifics including fabricated guidelines, statistics, or citations, and (4) bias, minimization, or ethical concerns. Messages could receive multiple flags across domains. A board-certified psychiatric-mental health nurse practitioner (PMHNP-BC) assigned severity classifications (high: block or mandatory rewrite required; medium: clinician review recommended; low: log for monitoring only) and recommended workflow actions for each flagged message. This study used only simulated AI-generated messages; no human subjects or protected health information were involved. Results: Of 200 messages evaluated, 102 (51.0%) received at least one language-level risk flag. At the message level, 80 messages (40.0%) were classified as high severity, requiring blocking or mandatory rewrite before patient delivery. Workflow actions were distributed as follows: 20 messages (10.0%) blocked, 20 (10.0%) required mandatory rewrite, 11 (5.5%) recommended for clinician review, and 149 (74.5%) allowed to proceed. At the flag level, 126 total risk flags were assigned across the 102 flagged messages (mean 1.24 flags per flagged message). By message-level category presence, overconfidence/false reassurance was most frequent (24 messages), followed by scope violations (20), hallucinated specifics (16), and bias/ethical risk (3). By flag-level severity, 80 flags (63.5%) were high severity and 46 (36.5%) were medium severity; no low-severity flags were assigned. Conclusions: Language-level safety risk in AI-generated patient-facing messages is frequent and clinically meaningful, affecting more than half of evaluated messages. A structured, clinician-defined governance framework can feasibly identify scope violations, overconfidence, and hallucinated content, providing an auditable mechanism to reduce the likelihood of unsafe messages reaching patients. Health systems deploying generative AI for patient communication should incorporate language-level safety evaluation into governance workflows. Multi-reviewer validation studies and development of automated detection methods are needed before operational deployment at scale.

Background: The cognitive paradigm in medical education is undergoing a transition from traditional knowledge transmission to learner-centered knowledge construction. In China, this shift is aligned with the Outline of the Plan for the Construction of China into an Education Powerhouse (2024-2035), which mandates high-quality, intrinsic development in nursing curricula. While Constructivist Learning Theory (CLT)–based teaching methods (eg, PBL, CBL, and situational simulation) have been widely explored across Chinese nursing institutions, the evidentiary base remains geographically fragmented and methodologically heterogeneous. A systematic synthesis is required to inform national evidence-based educational reforms. Objective: This protocol describes a systematic review and meta-analysis designed to evaluate the effectiveness of CLT-based teaching methods versus traditional lecture-based models on Chinese nursing students’ theoretical knowledge, practical skills, self-directed learning ability, and critical thinking disposition. Methods: A comprehensive systematic search will be conducted across nine electronic databases: PubMed, Web of Science, the Cochrane Library, Embase, CINAHL, China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Database (Chinese Scientific and Technological Journal Database), and China Biology Medicine (CBM). The search period spans from database inception to September 27, 2025, with an update scheduled for May 31, 2026. Randomized controlled trials and quasi-experimental studies involving Chinese nursing students will be included. Two independent reviewers will screen titles and abstracts, perform full-text retrieval, and extract data using standardized forms. Risk of bias will be assessed using the Cochrane Risk of Bias tool 2 (RoB 2) for randomized trials and the Joanna Briggs Institute (JBI) critical appraisal tools for quasi-experimental studies. Meta-analysis will be performed using Review Manager (RevMan) 5.4 and Stata 18.0, employing random-effects models and subgroup analyses based on educational level (eg, vocational vs. undergraduate) and intervention type. Results: This protocol was finalized in February 2026. A preliminary systematic search was conducted on September 27, 2025, identifying 990 records prior to deduplication. As of February 6, 2026, deduplication has been completed and title/abstract screening is underway. Full-text retrieval is expected to be completed by June 2026, and data extraction and risk-of-bias assessment are expected to be completed by July 2026. The final results manuscript is targeted for submission in September 2026. Conclusions: This review will provide a robust evidentiary foundation for the strategic deployment of constructivist methodologies in Chinese nursing education, specifically addressing the needs of vocational and undergraduate programs in the era of digital transformation.

Background: Multicomponent supervised exercise programs have demonstrated efficacy in improving physical performance and mitigating frailty in older adults, especially when adapted to functional capacity. However, evidence remains limited regarding their effects in community-dwelling frail and pre-frail individuals in Brazil. Objective: This protocol study aimed to evaluate the effects of a 12-week multicomponent supervised exercise program on frailty status, functional capacity, clinical-functional vulnerability, and fall risk in frail and pre-frail community-dwelling older people. Methods: This protocol describes the methodology of a single-blind, randomized controlled trial, which will assess a total of 60 participants aged 60 years and older that will be recruited from a community senior center in Rio Verde, Brazil, and randomly allocated to an intervention group (multicomponent supervised exercise based on the VIVIFRAIL model) or to a control group (educational workshops on healthy aging). The primary outcomes will be functional capacity (6-Minute Walk Test) and fall risk (Timed Up and Go Test), but covariates will include clinical-functional vulnerability (CFVI-20), cognitive status (MMSE), depressive symptoms (GDS-15), physical activity level (IPAQ), muscular mass (calf circumference), and fear of falling (FES-I). Assessments will be conducted at baseline and post-intervention. Results: This protocol will provide evidence regarding the effectiveness of a supervised multicomponent exercise program for improving frailty status, functional outcomes, and fall-related risk in a vulnerable population of Brazilian elderly. Conclusions: If effective, the intervention may offer a scalable, low-cost, and culturally appropriate strategy to promote healthy aging and reduce physical decline in community settings vulnerable subgroups.

Background: With the acceleration of global aging and rising demand for orthopedic surgeries, Enhanced Recovery After Surgery (ERAS) protocols have shortened hospital stays but created a "transitional care gap," shifting complex rehabilitation tasks to the home setting. While artificial intelligence (AI) offers potential solutions, patient perceptions regarding its role—ranging from informational chatbots to functional monitoring systems—remain underexplored. Objective: This study aims to map the evolution of care needs from hospital to home recovery, and to identify specific preferences and independent predictors of AI acceptance in orthopedic transitional care. Methods: A multicenter, cross-sectional survey was conducted with orthopedic patients across 33 hospitals in Guangdong, China. A total of 860 questionnaires were initially collected, and 752 valid responses were included in the final analysis after strict quality control (excluding response duration ≤ 180s). Data were collected on demographics, evolving task priorities across the care continuum, and perceived challenges based on an extended Technology Acceptance Model (TAM). The structure of perceived challenges was validated using Exploratory Factor Analysis (EFA). Descriptive mapping and multivariable logistic regression were performed to identify the "evolving preferences" and independent determinants of the willingness to use AI assistants. Results: Overall willingness to use AI was high (604/752, 80.3%). Patient priorities exhibited a fundamental shift from "passive compliance" (e.g., pain management, understanding instructions) during hospitalization to "active safety assurance" (e.g., fall prevention, motion correction) in the home setting. EFA identified 3 distinct challenge dimensions: Home Rehabilitation Self-Management Barriers, Lack of Professional Support, and Symptom Uncertainty. In multivariate analysis, significant predictors of AI acceptance included presence of comorbidities (adjusted Odds Ratio [aOR] 1.72, 95% CI 1.09–2.69), older age (aOR 1.02, 95% CI 1.00–1.03), and progression to later rehabilitation stages (aOR 1.28, 95% CI 1.01–1.62). Conclusions: The transition from hospital to home involves a fundamental shift in patient needs from information acquisition to functional safety assurance. AI acceptance in this context is driven by a "Vulnerability Hypothesis," where older and clinically vulnerable patients actively seek digital support to overcome physical execution barriers. However, widespread adoption is currently constrained by a digital divide related to geography and family support. To be clinically effective, future orthopedic AI systems must move beyond generic chatbots to become "Hybrid Coaches"—integrating computer vision and sensor technology to provide real-time motion correction and fall prevention—thereby addressing the specific "Action Gap" that defines the transitional care period. Clinical Trial: This study is not a clinical trial, so trial registration is not required.

Background: Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality worldwide. ABO blood group phenotypes have been associated with thrombosis, endothelial dysfunction, and inflammation, which are key mechanisms implicated in preeclampsia pathogenesis. Observational studies have reported inconsistent associations between maternal ABO blood group and preeclampsia, and several new studies have been published since the last comprehensive meta-analysis in 2021. Objective: An updated systematic review and meta-analysis is warranted to provide robust evidence on this association. Methods: This protocol follows the PRISMA-P 2015 guidelines and has been prospectively registered in the Open Science Framework (OSF) under the identifier 10.17605/OSF.IO/E3KTG (https://osf.io/zm4nf). Observational studies (case-control, cohort, and cross-sectional) reporting maternal ABO blood group and preeclampsia outcomes will be included. A systematic search will be conducted in PubMed/Medline, Embase, Scopus, Web of Science, and the Cochrane Library for studies published from January 2000 to October 31, 2025. Grey literature sources including Google Scholar, ProQuest Dissertations, and conference abstracts will also be searched. Two independent reviewers will perform study selection, data extraction, and risk of bias assessment using the Newcastle-Ottawa Scale. A random-effects meta-analysis will be performed to pool odds ratios for each blood group, and heterogeneity will be assessed using Cochran’s Q and I² statistics. Subgroup and sensitivity analyses will be conducted, and publication bias will be evaluated using funnel plots, Egger’s test, and trim-and-fill method. The certainty of evidence will be assessed using the GRADE approach. Conclusions: This review will provide updated evidence on whether maternal ABO blood group is associated with preeclampsia risk. The findings may help determine whether ABO blood group could serve as a risk marker for preeclampsia and inform future research and clinical practice. Clinical Trial: OSF 10.17605/OSF.IO/E3KTG

Background: Dravet syndrome is a complex developmental and epileptic encephalopathy characterized by treatment-resistant seizures and multiple comorbidities that significantly affect quality of life. Traditional clinic-based assessments often fail to capture real-world functional abilities and behavioral changes. Objective: This project aimed to explore the feasibility of co-creating digital outcome measures with caregivers to inform future clinical research. Methods: A multi-stage Patient and Public Involvement activity was conducted in collaboration with a patient advocacy organization and a digital health company. The process included a literature review, a caregiver survey to identify meaningful aspects of health, a design workshop to refine priorities and technology preferences, and usability testing of a prototype app. The app incorporated questionnaires, seizure diaries, and video-based tasks designed to reflect daily functional abilities. Feedback was collected through structured surveys and a follow-up workshop. No statistical hypothesis testing was performed; descriptive insights guided iterative design. Results: Fifty caregivers completed the survey, highlighting neuropsychiatric symptoms, independence, and motor limitations as key priorities. Eight caregivers participated in the design workshop, emphasizing flexibility, age-appropriate tasks, and reduced reporting burden. Usability testing with five caregivers demonstrated high acceptance of digital tools and willingness to engage with app features. Participants valued customizable options, such as open-text fields and adaptable task lists, but noted challenges with video recording and repetitive questionnaires. Feedback underscored the need for simplified workflows and individualized approaches to maintain engagement. Conclusions: Co-creation with caregivers is feasible and essential for developing meaningful digital outcome measures in Dravet syndrome. Video-based tasks and remote reporting tools show promise for capturing motor, cognitive, and behavioral domains beyond seizure frequency. Future work should focus on iterative refinement and formal validation of these measures as endpoints in clinical trials, ensuring they reflect outcomes that matter most to patients and families.

Background: Patients receiving systemic anti-cancer therapy can deteriorate rapidly between appointments, yet acute oncology services often rely on reactive helplines with limited symptom visibility. Objective: To evaluate the feasibility, safety, and workflow integration of OncsCare, a digital symptom triage platform mapping patient-reported symptoms to UK Oncology Nursing Society (UKONS) acuity tiers with episode-based clinician review. Methods: This 10-week service evaluation (July–September 2025) implemented OncsCare within a UK tertiary acute oncology service. Patients completed daily symptom check-ins mapped to UKONS-informed green/amber/red tiers. Alerts were grouped into episode-level triage events using prespecified rules (48-hour window, symptom-domain continuity) to represent operational workload. Outcomes included engagement, alert distribution, escalation pathways, review timeliness, and safety signals via structured case-finding. Results: Thirty-two patients participated (none withdrew). Daily check-in completion rate was 91.7% (1444/1574 expected patient-days). From 362 amber/red alerts, 62 episodes were generated; 38.7% (24/62) were clinically actionable, resulting in telephone management (50%), acute care assessment (37.5%), emergency referral (8.3%), or admission (4.2%). Median review time for in-hours red alerts was 47 minutes. Predefined safety case-finding identified no intervention-attributable safety signals. Patients reported increased home reassurance (85%) and clinicians reported improved situational awareness without increased workload. Conclusions: UKONS-informed digital triage with episode-based review demonstrated feasibility and safety in routine acute oncology care. This operational model addresses alert fragmentation and supports multicentre evaluation. Clinical Trial: Not applicable

Background: Chimeric antigen receptor (CAR) therapy is a novel cell editing technology and innovative form of cancer immunotherapy. An individual’s immune cells (T-cells) are removed from the body, engineered to target and limit the growth of cancer cells, and reinfused into the patient’s body. The one-time treatment is expensive ($500,000 plus hospital costs), and requires specialized care to treat and manage the associated side effects, such as cytokine release syndrome (CRS), and other serious health issues including cognitive confusion, infertility, secondary malignancies, and compromised long term quality of life. At the same time, CAR T has been highly successful for patients with advanced blood cancers and no remaining treatment options. The CAR T landscape is changing rapidly, and product approvals have outpaced the capacity for researchers to collect long term evidence related to survival or predictive biomarkers that might better prioritize patients. Because CAR T is offered exclusively in urban cancer centres with access to cell manufacturing capacity, equitable access has been challenging. At the same time there is considerable demand and social hype about CAR T as a cancer cure despite the risks and uncertainty of the technology. Objective: We aimed to determine the dominant perspectives and nature of the information on CAR T-cell therapy available to the public in the online environment. Methods: In this qualitative study, we conducted a comprehensive search of websites including professional, medical, corporate, health-based, news media, and blogs to capture the diversity of online sources and their perspectives presenting information on CAR T-cell therapy. Fifty-one webpages met the study criteria and comprised the data set in this review. The content of the sites was reviewed and analyzed using a critical and interpretive descriptive lens. Results: We classified the website information into four dominant major themes characterizing CAR T-cell therapy: 1) patient stories of success, magic and hope; 2) medical science explainers; 3) economic perspectives; and 4) ethical discussions and complex arguments. With the exception of the sites that presented ethical discussions and complex information, the online environment positioned CAR T as revolutionary, curative, and the future of cancer treatment. Side effects were generally minimized, and collective dilemmas such as sustainability for the healthcare system, equitable access, and issues of prioritization were frequently sidelined or absent. Conclusions: The persuasive tone of online CAR T information combined with the increasingly blurred distinctions between research and care in genetic medical technologies suggests that obtaining informed consent or refusal may place too much onus on individual patients. In an evolving technological landscape such as CAR T, determining the acceptable risks and benefits is a question that ethically requires broader, as well as more inclusive, societal deliberation.

Background: “Empathy” is widely discussed in health and care settings and is increasingly claimed as an attribute of AI (artificial intelligence) systems (e.g., socially assistive robots, chatbots), but the term is used inconsistently across the literature. In research on AI in these settings, it is often unclear what authors mean by “empathic AI”, what systems do that is intended to be empathic, and how empathy is assessed. This matters because perceived empathy can shape users’ experience of AI-mediated support and their willingness to engage with these systems. Objective: To map how empathy is defined, operationalised, and evaluated in peer-reviewed AI research in health and care settings, and to identify recurring design features associated with higher perceived empathy. Methods: This protocol outlines a scoping review following Joanna Briggs Institute (JBI) guidance and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). We use “AI” as an umbrella term and will extract and classify each system’s type (e.g., rule-based or large language model–based). We will search PubMed (MEDLINE), Embase, PsycINFO, CINAHL, Scopus, IEEE Xplore, and the ACM Digital Library. Two reviewers will screen titles/abstracts (ASReview) and full texts (Rayyan). We will extract study characteristics, empathy definitions/framing, empathy-related system behaviours/design features, and evaluation methods, and synthesise findings thematically. Results: The review will produce (1) a summary of how empathy is defined in AI research in health and care settings, (2) a grouped list of the main empathic behaviours and design features described, and (3) an overview of how empathy is measured across studies. Where studies report empathy ratings, we will summarise which features are most commonly present in higher-rated systems within comparable contexts. Conclusions: The review will provide a clearer picture of what researchers mean by “AI empathy” in health and care settings and what system features are most commonly used when trying to build it. These findings may help guide the development of more empathic AI systems.

Background: Emerging adults (EAs), typically ranging from late adolescence into mid- to late-twenties, navigate a transitional period marked by rapid developmental, social, and psychological change. Despite heightened vulnerability to mental health concerns during this stage, service systems are often fragmented, with gaps between adolescent and adult care streams that leave many EAs without developmentally appropriate support. In response, developing approaches such as transdiagnostic stratification, which structures care around shared symptom processes and informs treatment intensity, and digital measurement-based care (dMBC), based on routine patient-reported outcome measures (PROMs), have gained traction but remain challenging to implement consistently. This reinforces the need for Rapid Learning Health System (RLHS) approaches that leverage continuous data and feedback for ongoing improvement, as well as co-design methods that meaningfully integrate EA perspectives into service improvement. Objective: This research protocol outlines a co-design study situated within an RLHS to develop practical strategies and resources to support the sustained implementation of dMBC within EA mental health services. Anticipated outputs include clinician-facing workflow supports, guidance for using client-reported data in clinical decision-making, EA-oriented materials to support engagement with measures, and implementation planning resources to support uptake across the care pathway. Each co-designed output will be developed to function across core stages of care, including intake, treatment decision-making, therapy, and discharge. Methods: A concurrent multi-methods design will be employed, integrating quantitative and qualitative approaches within a dual methodological framework combining User-Centered Design with Participatory Design to structure the co-design process and guide the development of implementation outputs. The process will center the perspectives of EAs accessing services and clinical staff to actively collaborate in informing the development and refinement of study outputs. Results: As the study is underway, findings will be reported upon study completion. Conclusions: This study is expected to demonstrate the value of integrating co-design within an RLHS to advance more responsive, contextually grounded dMBC implementation in EA mental health care, while also contributing insights that can strengthen future co-design efforts with this population.

Background: Digital technologies are becoming an important part of healthcare, including for individuals with ADHD. Digital health innovations present valuable opportunities to provide flexible and tailored support for their diverse needs, together with significant challenges. Attentional, organisational, and motivational characteristics associated with ADHD may affect how individuals engage with digital tools. Potential risks include additional access barriers, exclusion of underserved groups, and diminished quality of care. To help reduce these risks, the development, evaluation, and implementation of digital tools must be person-centred and guided by a comprehensive understanding of diverse needs of all stakeholders. Objective: To advance research in this area, a multidisciplinary panel of ADHD specialists, technology experts, and individuals with lived experience of ADHD was formed. The panel worked together to agree on key priorities and considerations for developing, evaluating, and implementing digital technologies for ADHD. Recommendations are designed to be shared with the wider research community and to guide innovations in ADHD digital health to improve care. Methods: A modified Delphi approach was used to develop consensus. Key statements were drafted, building on discussions held during The European Network for ADHD (EUNETHYDIS) Special Interest Group (SIG) meeting in 2024. An Expert Panel that included additional key stakeholders was convened. Draft statements were shared with Panel members via a two-round Delphi survey and discussion meetings, with final statements co-produced by the Panel. Insights from multiple perspectives were incorporated, and consensus agreement sought. Refined statements were shared with EUNETHYDIS members for ratification. Panel members were invited to contribute as co-authors. Results: An expert panel of 30 members (21 EUNETHYDIS SIG members, 9 invited experts) co-produced 30 consensus statements on ADHD and digital health. Agreement ranged from 78.5-100% for the first round (19 statements), and 96.4-100% for the second round (30 statements). Final statements covered four topic areas: Opportunities and aspirations, Development and evaluation, Implementation, and Risks and unintended consequences. These were ratified in September 2025 by the EUNETHYDIS. Conclusions: This consensus process provides the first comprehensive set of key considerations for digital health care for people with ADHD and demonstrates the feasibility of achieving expert agreement on complex, rapidly evolving topics, such as digital health. Future work should focus on translating these considerations into more specific and practical implementation frameworks, identifying priorities, and connecting them to real-life stories and empirical evidence.

Background: Despite recent declines in unintended teen pregnancies attributed to family planning services, socioeconomically disadvantaged and highly mobile youth (HMY)—those experiencing frequent residential transitions—remain disproportionately at risk. Traditional teen pregnancy prevention (TPP) programs often fail to effectively engage these youth due to their unstable life circumstances and limited access to conventional prevention resources. Objective: This paper describes the design, usability testing, and key lessons learned from the development of gamification elements involving interactive narratives for "My Future-Self (MFS)," an innovative, hybrid intervention tailored specifically for HMY. This manuscript highlights the experience of interdisciplinary collaboration in the development of gamified elements of behavioral change interventions. Methods: We employed a User-Centered Design (UCD) framework, emphasizing iterative collaboration among adolescent unintended pregnancy prevention intervention scientists, game designers, and HMY advisors (N=96; mean age=19.86, SD=1.41). Initial surveys assessed HMY’s game aesthetics preferences, technology access, intimate relationships, and specific life experience with medical professionals and use of contraception in order to guide prototype development of gamified interactive content. Two 10 minute gaming activities were developed; one around visiting a physician office to discuss contraception and one using scenarios to practice healthy communication with an intimate partner. Iterative usability testing involved structured playtesting sessions with 12 youth with HMY experience utilizing think-aloud protocols, semi-structured interviews, and thematic feedback analysis. Throughout development, distinct goals representing a) intervention developers (i.e. contributions to behavior change) and b) game designer/producers (i.e. user engagement) were clarified, aligned, and operationalized to optimize gaming elements’ contribution to the small group intervention’s behavior change effectiveness. Results: Playtesting revealed high user appreciation for realistic and immersive scenarios; however, feedback also underscored the necessity for clearer context and increased user agency within the intimate partner gaming element. Iterative refinements resolved usability barriers and significantly enhanced gaming elements’ acceptability. Key lessons learned included the critical importance of clearly defining and aligning interdisciplinary goals early in the design process, positioning intervention scientists as lead designers, adapting gamified interventions to realistic user-engagement expectations, and proactively integrating cultural relevance throughout inclusive content. Conclusions: Explicitly addressing interventionists’ and game designers’ distinct goals was crucial to achieving successful interdisciplinary alignment. Employing a collaborative, iterative UCD approach significantly strengthened interdisciplinary understanding of the gaming elements’ purpose, enhancing the design relevance and usability of the MFS gamified intervention for HMY. The identified lessons learned provide valuable insights for future development and production of gamified health interventions through the partnering of intervention developers with game designers and end users of resultant intervention program.

This case study examined the feasibility of using consumer-grade wearable devices for longitudinal sleep tracking and explored how changes in sleep patterns relate to balance performance. Two college students participated over four months: Participant 1 (P1) used an Apple Watch Series 5 and an OURA ring; Participant 2 (P2) used a Fitbit Charge 5 and an OURA ring. Participants were assigned different wearable devices to assess device-specific feasibility and variability in sleep-tracking accuracy. Sleep data were collected continuously, including time in bed (TIB), total sleep time, sleep efficiency, wake after sleep onset (WASO), sleep stages, and sleep onset timing. Both participants also completed a daily sleep diary and underwent monthly balance assessments using the Bertec® Balance Advantage Sensory Organization Test (SOT). Wearables showed varying accuracy in estimating TIB: the OURA ring overestimated TIB by 15–22 minutes, the Fitbit by 27 minutes, while the Apple Watch slightly underestimated it by 9 minutes. Excellent agreement was observed in sleep duration estimates between the OURA ring and Apple Watch (ICC=0.97) and between the OURA and Fitbit (ICC=0.99), but agreement was lower for WASO, deep sleep, and sleep efficiency. Sleep variability appeared to influence balance outcomes. Fluctuations in sleep timing and duration corresponded to changes in SOT visual subscale scores, suggesting increased postural sway with irregular sleep patterns. Missing data rates were acceptable, ranging from 0–25% across devices. For P1, missingness was highest for the OURA (25%) and Fitbit (20.3%), but zero for the sleep diary. For P2, the Apple Watch had a 14.1% missing rate, the OURA 9.4%, and the sleep diary 6.25%. In conclusion, all tested wearables demonstrated feasibility for long-term sleep monitoring, though measurement discrepancies highlight the need to align device choice with research goals. Variations in sleep consistency may affect postural stability, reinforcing the importance of accurate, continuous sleep tracking in balance research. Due to the small sample size, findings are illustrative and not generalizable.

Background: Artificial intelligence (AI) is an increasingly prominent feature of contemporary healthcare, with medical AI systems beginning to support diagnostic and therapeutic processes in many clinical domains. Alongside the anticipated benefits of these technologies, their introduction also raises broader questions about how clinical work and professional roles may change. In particular, medical AI systems may affect physician autonomy, a key factor influencing the acceptance and long-term implementation of new medical technologies. Objective: The aim of this study was to develop and pretest a semi-structured interview guide concerning the potential effects of medical AI systems on physician autonomy. Methods: The interview guide was theoretically grounded in a seven-component model of physician autonomy proposed by Schulz and Harrison. Semi-structured qualitative interviews were conducted with a sample of seven hospital physicians. Interview recordings were transcribed and analyzed using a hybrid inductive–deductive thematic approach: themes were first identified inductively from participant responses and subsequently mapped onto the seven-component model of physician autonomy proposed by Schulz and Harrison. Data were analyzed to assess both the potential effects of medical AI systems on physician autonomy and the methodological adequacy of the interview guide. Results: Most participants did not express strong concerns about losing clinical autonomy through the introduction of AI systems. However, several autonomy-related risks were identified, including potential deskilling, automation bias, limited system explainability, and increasing economic or cost-related pressures. Participants emphasized that AI should serve as a supportive tool rather than a substitute for physician judgment. All physicians agreed that AI systems should not replace clinicians as primary clinical decision-makers. Conclusions: Medical AI was largely viewed as compatible with physician autonomy, yet participants highlighted important risks that warrant attention in future research and system design. Our findings suggest that autonomy-related concerns extend beyond direct loss of decision-making authority and include broader professional, cognitive, and organizational dimensions. However, our inductively identified themes and subthemes did not fully reflect all components of physician autonomy, indicating the need for further refinement of how to assess physician autonomy in qualitative research.

Formative evaluation is widely used in implementation science to anticipate barriers and facilitators prior to the deployment of health technologies, typically relying on stakeholders’ reported beliefs collected before real-world exposure. This approach has proved informative for many digital health tools, but its application to immersive and embodied technologies such as extended reality (XR) warrants closer scrutiny. XR interventions delivered through head-mounted displays depend on spatial perception and sensorimotor engagement, meaning that implementation-relevant properties, including comfort, perceived intrusiveness, safety, and workflow disruption, often become apparent only through direct interaction. At the same time, large segments of the healthcare workforce remain XR-naïve, such that pre-use judgements are frequently shaped by anticipation rather than experience. Drawing on literature from implementation science, grounded cognition, and human–computer interaction, this viewpoint argues that perception-based formative evaluation, when applied through frameworks developed for screen-based technologies, is vulnerable to misclassifying barriers and facilitators in XR adoption. Rather than questioning formative evaluation as a methodological approach, we identify a boundary condition for its interpretability in experience-dependent technologies and propose a pragmatic refinement: incorporating brief experiential familiarisation before eliciting stakeholder perceptions to strengthen early-stage assessment and improve alignment with real-world implementation decisions.

Background: Large language models (LLMs) are increasingly used to extract information from electronic health records (EHRs). Given the rapid pace of LLM development, robust scenario-specific benchmarks are essential to evaluate clinical usefulness and support safe deployment. Objective: To compare contemporary LLMs on structured data extraction from real neurosurgical EHRs written in the Czech language. Methods: In a prospective single-center cohort, 172 hospitalized patients provided informed consent for use of anonymized EHRs. For each patient, predefined records were collected and concatenated. Ground truth for 35 data points was established by dual extraction with consensus. A standardized prompt requesting JSON output was submitted to 19 LLMs. Primary outcome was overall accuracy; secondary outcomes were category-level accuracy and proportion of complete machine-readable outputs. Results: 6,264 documents were collected (median 33 per patient). Ground truth was established with 92.6% initial inter-rater agreement before consensus seeking. Several models produced complete JSON outputs for 100% of cases (Claude 4.1 Opus, Grok 4, Gemini 2.5 Flash); GPT-4.1 (DeepSearch) and GPT-5 completed 99.4%. Highest accuracy was achieved by GPT-4.1 (87.6%), followed by GPT-4.5 (85.6%), Claude 4.1 (84.8%), and Grok 4 (84.2%). Accuracy declined by data type: binary (up to 95%), numeric (~89%), multiple-choice (~75%), and short text (~78%). Conclusions: Currently available LLMs can reliably extract structured clinical information from full, non-English EHRs, while older or smaller models show major limitations. A hybrid workflow—automated extraction with targeted validation—appears practical for research use.

Background: Despite the effectiveness of bariatric surgery in the treatment of severe obesity, a substantial proportion of patients experience insufficient weight loss or weight regain over time. Evidence indicates that behavioral factors and mental health conditions play a central role in these outcomes, representing strategic targets for educational and technology-based self-monitoring interventions. Objective: This study aimed to develop and validate the content of a mobile application designed to support patients in mental health self-monitoring and to encourage behavioral changes, with the goal of improving surgical outcomes, preventing weight regain, and promoting long-term psychological well-being. Methods: This was a formative research study focused on the development and content validation of an educational digital health intervention, conducted according to the Systematic Instructional Design model, encompassing the analysis, design/development, and validation phases. Content validation was performed by an expert committee based on Pasquali’s criteria. Interrater agreement was quantitatively assessed using the Content Validity Index (CVI), considering the domains of clarity and relevance. Results: The application was developed with 11 screens and integrates validated psychometric instruments for self-monitoring of major mental health conditions, including the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Modified Yale Food Addiction Scale 2.0 (mYFAS 2.0), and Alcohol Use Disorders Identification Test (AUDIT). In addition, the platform includes body weight monitoring, physical activity tracking, and access to educational content on healthy eating and mental health. The app was designed based on scientific evidence and incorporates motivational strategies such as goal setting, automated alerts, and encouragement of multidisciplinary follow-up. All screens achieved full agreement regarding relevance. One screen did not reach the minimum clarity threshold in the first evaluation round and was subsequently revised. In the second round, it achieved 92.3% clarity and 100% relevance. Conclusions: The findings indicate that the developed application demonstrates adequate content validity and represents a promising digital tool to support postoperative care for patients undergoing bariatric surgery by enabling self-monitoring of key mental health conditions and promoting behavioral strategies aimed at preventing weight regain. Clinical Trial: This study did not constitute a clinical trial.

Background: Many countries face challenges in youth mental health, including stigma around help-seeking, limited accessibility to services, and undersupply of trained professionals. Online peer support platforms show promise in addressing these barriers. A government-supported platform called let’s talk launched in Singapore in 2022 to support youth aged 17-35. The anonymous and moderated forum allows youth to discuss mental health topics and life challenges with peers, peer supporters, and professionals. Objective: The objectives are to (1) describe the design framework for let’s talk, including its Theory of Change; (2) conduct a process evaluation on data collected over the first three years of operation; and (3) summarize and discuss our learnings. The findings provide a replicable framework that may guide the design of similar platforms and inform impact evaluation studies. Methods: Key features of let’s talk include co-development with youths and mental health professionals, anonymity, trust and safety through moderation and government endorsement, and five dedicated pathways for key user journeys. Most notably, the Ask-A-Therapist pathway provides access to professional support on the forum and the Peer Supporter pathway trains and empowers youths to provide meaningful support to their peers. Process evaluation data were collected from 1 July 2022 to 30 June 2025. We analyzed platform-wide and feature-specific reach, engagement, and growth metrics by year. We documented learnings from implementation described by the platform development team. Results: In its first three years, let’s talk received an estimated 51,636 non-bounced (meaningful activity) visitors, representing 5.2% of the platform’s target population of 17–35-year-olds in Singapore. In total, 17,158 users (33.2% of non-bounced visitors) created an account and 3,489 (20.3%) of those users posted at least once. The most popular feature of the platform was Ask-A-Therapist, which saw 1,548 original (thread-starting) questions posted from 1,037 unique users and a total of 6,865 posts (61.9% of all posting activity). The 156 Peer Supporters were the most active users, representing 0.9% of all registered users yet contributing 2,175 posts (19.6% of all posting activity). The let’s talk features aiming to bridge the online-offline divide and to encourage self-care training were not popularly used. Engagement patterns revealed that professionally-moderated peer support and direct access to professionals were the primary drivers of sustained use, while features promoting self-directed activities had limited uptake. Conclusions: let’s talk achieved meaningful reach (5.2% of target population) and engagement through two key design principles: (1) low-barrier access to professional support via Ask-A-Therapist, and (2) training and empowering peer supporters as highly engaged community leaders. Our findings suggest that the core value proposition of platforms like let’s talk is human connection and expert guidance. Our framework and implementation learnings provide practical guidance for adapting this model to diverse cultural contexts.

Background: Mobile health (mHealth) applications for menstrual cycle and fertility tracking are widely used to support self-monitoring, reproductive planning, and health awareness among women. While these tools promise personalized predictions and convenient access to reproductive health information, concerns persist regarding their clinical accuracy, adaptability to irregular cycles, transparency of algorithms, and real-world user experience. Objective: This structured review aimed to evaluate the features, physiological integration, predictive performance, validation practices, and user-reported outcomes of mobile applications designed for menstrual and fertility tracking, and to contextualize current evidence using COSMIN and ISPOR evaluation frameworks. Methods: A structured narrative review with systematic elements was conducted following the PRISMA-like reporting framework. Literature published between January 2013 and October 2025 was identified through searches of PubMed, EMBASE, Scopus, and Web of Science, supplemented by semantic and citation-based searches in the Semantic Scholar, OpenAlex, and Google Scholar databases. AI-assisted relevance ranking supported the initial screening, followed by an independent human review. Forty studies meeting the predefined eligibility criteria were included in the qualitative synthesis. Owing to the heterogeneity in study designs, outcomes, and validation methods, a quantitative meta-analysis was not performed. Results: Of the 40 included studies, most were observational and relied on self-reported data from predominantly high-income, technology-literate population. Twenty-four applications incorporated physiological inputs, such as basal body temperature, luteinizing hormone measurements, or wearable-derived metrics, whereas others relied primarily on calendar-based predictions. Multiparameter and sensor-augmented approaches generally demonstrate higher agreement with biological or clinical reference standards than calendar-only methods, with reported fertile window prediction accuracies ranging from approximately 85% to 90% under optimal conditions. However, only a small subset of applications has reported formal clinical validation or regulatory clearance. User satisfaction was strongly associated with perceived accuracy, personalization, and usability, whereas inaccurate predictions, particularly among users with irregular cycles, were linked to frustration, anxiety, and high attrition. Conclusions: Menstrual and fertility tracking applications that integrate physiological signals outperform calendar-based approaches in terms of predictive performance; however, robust clinical validation, transparency, and inclusivity remain limited. Reported accuracy metrics should be interpreted cautiously because real-world adherence, irregular cycle patterns, and algorithmic bias substantially affect reliability. These tools are best positioned as decision-support and self-awareness technologies, rather than as autonomous diagnostic instruments. Future evaluations should apply standardized frameworks, such as COSMIN and ISPOR, explicitly communicate uncertainty, and prioritize diverse and irregular cycle populations to ensure equitable and clinically meaningful digital reproductive health solutions.

Young people are among the fastest adopters of digital and AI-enabled mental health tools, yet they remain marginal to the research and design processes that shape these technologies. This Viewpoint examines a persistent participation gap in digital youth mental health research (DYMH): while co-production and patient and public involvement (PPI) are widely invoked as best practice, youth involvement is frequently superficial, inconsistent, or confined to late-stage consultation. As a result, digital mental health innovations risk misalignment with young people’s lived realities, priorities, and vulnerabilities.
We identify three interrelated drivers of this gap. First, conceptual and linguistic fragmentation obscures what “participation” entails in practice, with terms such as co-design, co-production, user-centred design, and PPI used interchangeably despite reflecting different assumptions about power, influence, and decision-making. Second, participation is often uneven across the research lifecycle, with young people involved in ideation or usability testing but excluded from problem formulation, theory selection, implementation, and evaluation. Third, institutional barriers - including ethics review processes, consent requirements, funding constraints, and adult-centric research norms - systematically limit meaningful youth partnership.
We argue that closing the participation gap is both an ethical imperative and a practical necessity. As digital and generative AI tools increasingly shape how young people understand and manage mental health, youth must be recognised as legitimate co-producers of knowledge rather than passive end users. We call for clearer reporting of participatory models, greater attention to youth influence across the research lifecycle, and structural support to normalise meaningful youth involvement. Without such shifts, DYMH innovation risks being scalable but not safe, credible, or trustworthy.

Background: Substance use disorders account for a significant portion of the disease burden attributed to mental health globally, but measurement remains suboptimal. Studies assessing substance use typically rely on retrospective recall often over long periods of time. However, the episodic, contextual and event- or time-contingent nature of substance use call into question the validity of these traditional retrospective measurement methods. One method to overcome these limitations is ecological momentary assessment (EMA). EMA methods repeatedly sample participant behaviours and experiences in real time, in the context in which they occur. Objective: This review aimed to systematically identify studies using EMA in substance use measurement, provide a comprehensive overview of the EMA methods used, and to provide a draft framework for reporting and methodological recommendations for future EMA studies in this field. Methods: Studies published between 2018 and 2023 were sourced from PubMed, Medline, Scopus, and PsycINFO via Ovid databases on 31st January 2023 using terms related to EMA, digital phenotyping, passive sensing, daily diary and specific terms for each drug type. Studies that actively or passively assessed thoughts and/or behaviour, in the participants’ natural environment/daily lives, in a repeated manner, at or close to the behaviour of interest (substance use), using either automatic prompts or notifications were included. Studies were included for all populations, any age, in any setting, any study design, including RCTs or experimental designs. This study was preregistered on PROSPERO (CRD42023400418). Results: The search identified 7053 articles of which 858 were reviewed in full, and 273 (n = 70,831 participants) were included and extracted. Most studies were conducted in the United States (80%) and focused on alcohol (78%) and cannabis use (30%) with or without the presence of other substance use. Alcohol and cannabis measurement co-occurred the most in 44 (16%) studies. Psychedelics (2%) were particularly understudied using EMA methods. PCP, bath salts, and inhalants were only measured in one study each. We found limited reporting consistency with respect to compliance, completion windows, attrition rates, survey duration and data collection technologies in EMA substance use studies. Sensing data were measured in a limited number of studies. Conclusions: While EMA is a powerful tool for capturing dynamic behaviours, inconsistencies in reporting and design transparency persist. Improving reporting practices, smart sensing and wearable integration, compliance monitoring alongside expanding EMA to underexplored substances such as psychedelics, will be critical to enhancing data quality and advancing the field.

Background: Strengthening the global health workforce is central to achieving Universal Health Coverage, yet existing approaches to measuring clinical competency remain resource-intensive, episodic, and difficult to scale, especially in low- and middle-income contexts. Recent advances in large language models (LLMs) have enabled AI-led simulated standardized patients (SSPs) that may offer scalable alternatives to traditional assessments. Objective: This study aims to systematically map and characterize the existing scope, design features, and validation approaches of AI-led SSP tools used for clinical competency assessment. Methods: We conducted a scoping review following JBI guidelines, searching MEDLINE, Embase, CINAHL, Education Source, and Web of Science from inception through June 2025. Two reviewers independently screened studies and extracted data across five domains: study characteristics and populations; frontend platform and interface features; backend AI models and architectures; user interaction and automatic feedback mechanisms; and tool evaluation methods and outcomes. Results: Between 2008 and 2025, 1,185 studies were identified and 21 studies met the inclusion criteria. Most described single-site pilot evaluations or prototype systems were developed within academic institutions in high-income countries, primarily targeting pre-licensure medical or nursing students. SSPs most commonly supported text-based, web-hosted history-taking, while simulations of physical examination, laboratory tests, diagnostic reasoning, and management planning were less common. Backend architectures relied heavily on human-authored case scripts and manually defined scoring criteria, with LLMs primarily enhancing conversational fluency rather than automating clinical reasoning or evaluation. Automated feedback and scoring were reported in approximately half of the studies and showed moderate-to-high agreement with human raters when evaluated, though validation evidence was heterogeneous and limited. Conclusions: AI-led SSPs are emerging as accessible and realistic tools for clinical competency assessment, particularly across all levels of medical education. However, current implementations remain early-stage, human-dependent, and narrowly validated, constraining their widespread use as standardized or scalable instruments for health system workforce evaluation. Advancing SSPs toward end-to-end automated assessment tools will require integrated system designs, rigorous validation, and intentional development for deployment across diverse and resource-constrained settings.

Background: African American women are among the least physically active demographic groups in the United States and face disproportionate burdens of chronic disease that are preventable through regular physical activity. Researchers are increasingly using mixed methods to better understand the behaviors, beliefs, and contextual factors that shape physical activity in this population. Objective: To identify, examine, and describe the key characteristics of mixed methods study designs used in research on the physical activity practices of African American women published within the past ten years, compare methodological approaches, identify gaps, and offer recommendations for future inquiry. Methods: Following the Joanna Briggs Institute (JBI) methodology for scoping reviews, we will implement a three-step search strategy across seven databases (Academic Search Ultimate, Agricultural & Environmental Science Database, APA PsycInfo, CINAHL Ultimate, PubMed, SocINDEX, and SPORTDiscus). Eligible studies are peer-reviewed, single mixed-methods investigations conducted in the United States that include adults (≥18 years) who identify as non-Hispanic African American/Black women, or samples with ≥50% African American women, with results reported by social classification. Two reviewers will independently screen and extract data with adjudication by a third reviewer as needed. We will chart designs (e.g., convergent, explanatory sequential, exploratory sequential), quantitative and qualitative methods, integration approaches (e.g., merging, connecting, embedding), and evidence of mixing (e.g., transformation, comparison, synthesis). Results will be summarized narratively, tabulated, and visualized in a frequency flow diagram. The process will be documented using a PRISMA 2020 flow diagram. Results: As this is a protocol, no results are reported. The initial search was piloted on February 1, 2026. We anticipate completing study selection, data charting, and synthesis by May 2026, with the completed review submitted in July 2026. Conclusions: Mapping the application of mixed methods in studies of African American women’s physical activity will reveal methodological patterns and gaps, guiding stronger, equity-centered research designs and reporting.

Background: Cardiac myxomas (CMs) are the most common benign primary cardiac tumours, most frequently originating from the left atrium, and less commonly from the right atrium. Despite being histologically benign, CMs can cause serious thromboembolic complications including stroke, acute coronary syndrome, limb ischemia, and visceral infarction. While previous studies have explored risk factors for thromboembolism, literature comprehensively synthesising the anatomical distribution, clinical patterns, and management of CMs remains limited. Objective: We intend to summarise the published evidence on the frequency, anatomical distribution, clinical presentations, and management implications of thromboembolic events associated with CMs. Methods: A systematic review will be conducted in accordance with PRISMA-P guidelines and registered on PROSPERO. Medline, Embase, and PubMed will be searched for studies reporting thromboembolic complications in patients with histologically or radiologically confirmed CMs. Eligible study designs include case reports, case series, cohort studies, and registries. Two reviewers will independently screen studies and extract data on patient demographics, tumour characteristics, embolic events (type, site, clinical presentation), diagnostics, management, and outcomes. Discrepancies will be resolved through discussion or third-party adjudication. Risk of bias will be assessed using Joanna Briggs Institute tools. Results: The review will summarise reported frequencies and anatomical distribution of embolic events, clinical presentations, associations with tumour characteristics, and management strategies. Case reports will be tabulated individually, while cohort and series data will be aggregated descriptively with quantitative summaries presented where feasible. Conclusions: This review aims to provide a comprehensive synthesis of thromboembolic complications associated with CMs, highlighting patterns, management strategies, and gaps in the current literature. Findings aim to improve clinical recognition, inform clinical management, and guide future research. Clinical Trial: This study is a systematic review and not a clinical trial. The review protocol was prospectively registered with PROSPERO (CRD420261299634).

Synthetic data (SD) has emerged as a promising tool for advancing cardiology research by enabling data access, enhancing patient privacy, and supporting the development of machine learning models. By generating artificial patient records that reflect real-world distributions, SD can accelerate clinical research, improve model performance for rare cardiovascular conditions, and facilitate transnational collaborations that would otherwise be restricted by data sharing barriers. Despite these advantages, the increasing use of SD raises important ethical, regulatory, and methodological concerns that remain insufficiently addressed. Key challenges include assessing the validity and generalizability of synthetic datasets, understanding their limitations in representing complex and heterogeneous patient populations, and preventing the amplification of existing biases in cardiovascular care. Regulatory frameworks such as GDPR and HIPAA safeguard privacy but do not fully account for emerging risks such as re-identification or data leakage, leaving uncertainty regarding the use of SD in evidence generation for medical devices or therapeutic evaluation. Technical constraints, including the reliability of generative models and the difficulty of capturing nuanced clinical trajectories, further limit the clinical applicability of SD. As cardiology increasingly intersects with artificial intelligence and digital health technologies, ensuring rigorous methodological standards, transparent validation, and clear governance mechanisms is essential to harness SD responsibly. This Viewpoint highlights the opportunities and blind spots associated with SD and virtual patients in cardiology and underscores the need for harmonized regulatory guidance and ethical safeguards to support their meaningful integration into research and clinical practice.

Background: Primary care physicians in resource-constrained settings, particularly within low-income and middle-income countries (LMICs), frequently encounter a "diagnostic gap" when managing complex, rare, or multisystemic pathologies. While Large Language Models (LLMs) demonstrate significant potential to augment clinical reasoning, current state-of-the-art solutions rely predominantly on high-bandwidth cloud infrastructure, limiting their deployment in regions with unstable internet connectivity and strict data sovereignty regulations. Objective: The prevailing technological consensus in computer science suggests that "Agentic Workflows" or Multi-Agent Systems (MAS)—which orchestrate multiple models to simulate collective reasoning—inherently offer superior accuracy and safety compared to single models. However, the comparative efficacy, safety, and cost-effectiveness of complex MAS versus single localised models in offline, hardware-limited environments remain unproven. Methods: We conducted a prospective comparative benchmarking study using the DiagnosisArena dataset, comprising 915 complex clinical cases across 28 medical specialties. To simulate a secure, offline primary care environment, we evaluated five locally deployed single open-source LLMs (GPT-oss-20b Llama3.1-70B, Qwen3-32B, DeepSeek-R1-32B, Gemma3-27B) against two Multi-Agent architectures: a Standard voting ensemble and a novel hierarchical Adaptive Weighted System. All models were hosted on a local server (4×NVIDIA A100) using the Dify platform. Performance was adjudicated against a Reference Standard established by the consensus of three board-certified physicians using a dual-metric system: a 10-point Diagnostic Recall Scale and a comprehensive Hallucination/Safety Index. Inference latency and computational resource utilisation were recorded to assess cost-effectiveness. Results: Contrary to the hypothesis that architectural complexity yields diagnostic precision, single high-performance models significantly outperformed complex ensembles. The single GPT-oss-20b model achieved the highest Diagnostic Recall Score (mean 4.68 [SD 3.82]), statistically surpassing the Adaptive Weighted Multi-Agent System (4.13 [SD 3.43]; p<0.001) and smaller models such as Gemma3-27B (2.89 [SD 3.89]; p<0.001). The Adaptive System, despite utilising dynamic routing, failed to outperform the median score of human physicians (4.22 [SD 3.62]; p=0.432). Furthermore, the inclusion of mid-tier models in the adaptive workflow introduced an "ensemble degradation" effect, significantly lowering the Safety Score compared to the single GPT-oss-20b model (4.99 vs 5.50; p<0.001) and reducing the rate of Top-1 correct diagnoses from 51.58% to 46.89%. Crucially, the single GPT-oss-20b model demonstrated superior efficiency with an average inference time of 30 seconds per case, compared to 200 seconds for the Standard Multi-Agent System—representing an 85% reduction in latency. Conclusions: In the context of clinical diagnosis, architectural complexity does not equate to clinical utility. We identified a phenomenon of "ensemble degradation," where integrating mid-tier models into ensembles dilutes the reasoning capabilities of strong base models through the introduction of diagnostic noise. For global health equity, implementation strategies should prioritise "Lean AI"—localising a single, robust open-source model—rather than orchestrating computationally expensive agent swarms. This approach provides a safer, more accurate, and scientifically validated path for bridging the diagnostic gap in resource-constrained primary care.

Background: Background: An increasing amount of TCM clinical data can be collected by software and equipment, forming diversified TCM data, which should typically be collected alongside clinical work. TCM diagnosis and treatment data collection is conducted concurrently with clinical work, typically. However, with the limited time, space, and human resources available in clinical work, collecting diversified TCM Data is difficult, which may affect the quality of the collected data. Objective: Objective: To develop recommendations for optimizing diversified traditional Chinese medicine (TCM) data collection. Methods: Method: A working group comprising 12 members was established. Based on previous survey findings regarding the burden of clinical data collection, the group developed a preliminary list of recommendations for optimizing diversified TCM data collection. A Delphi survey was conducted to investigate consensus levels(using a 5-point Likert scale for importance evaluation) on the list items, and open-ended opinions were also surveyed. If experts in the first round propose additions, deletions, or modifications, or if there is a lack of consensus on certain items, a next round of surveys will be conducted to obtain the experts' agreement rate on the related items. Results: Results: A total of 86 experts from China, the United Kingdom, and Singapore completed two rounds of surveys. Following the first Delphi survey, all items achieved agreement scores above 4, with coefficients of variation(CV) below 0.2. The working group revised 12 items based on open-ended opinions and resubmitted them for agreement assessment. All revised items achieved agreement rates of over 95%. Following the two-round survey process, the final version of the recommendations comprises 5 primary domains, 11 sub-domains, and 25 items. Conclusions: Conclusion: This study formulated recommendations for optimizing diversified TCM data collection. It is hoped that these recommendations will help clinical data collectors consider data collection in advance during the design phase

Background: Acute respiratory infections caused by influenza, respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain a major public health challenge in Europe. Although surveillance systems for these pathogens are well established, the past two decades have seen a rapid diversification of data streams supporting surveillance and research. This expanding and increasingly complex data landscape, combined with fragmentation across institutions, sectors, and countries, may limit timely evidence synthesis and effective public health decision-making. Objective: This scoping review aimed to identify and characterize data sources used for surveillance and research on influenza, RSV, and SARS-CoV-2 across 12 European countries over the past 20 years, and to examine their evolution over time, their alignment with research objectives, and geographic variation in data availability and use. Methods: We conducted a scoping review using an objective-driven analytical framework. Empirical reports published between January 2005 and September 2025 were identified in Medline, Web of Science, and Embase. Eligible reports focused on influenza, RSV, or SARS-CoV-2 and included data from Western (France, Belgium, Germany, Netherlands), Northern (Denmark, England, Finland, Sweden), Southern (Italy, Spain), and Eastern Europe (Poland, Romania). Clinical and interventional studies were excluded. Reports were classified according to four research objectives: epidemiological monitoring; evaluation of interventions; assessment of disease burden and health outcomes; and analyses of population adherence and trust toward public health measures. Data sources were grouped into nine categories, including surveillance systems, electronic health records (EHRs), registries, claims, surveys, digital, environmental, and integrated datasets. Results: A total of 2,564 empirical reports were included. Over time, respiratory virus research relied on an increasingly diverse set of data streams. While surveillance systems remained central, particularly for epidemiological monitoring, their relative dominance declined. From 2020 onward, there was a marked expansion in the use of EHRs, registries, claims data, digital sources, and linked or integrated datasets, alongside increased use of open-access data. Data source use varied by research objective: surveillance data predominated in monitoring and intervention evaluation; EHRs in studies of risk factors and treatment effectiveness; surveys in seroprevalence and public trust analyses; and claims data in assessments of economic burden. Substantial geographic disparities were observed. Northern European countries more frequently used linked and multi-source datasets, whereas Western and Southern Europe relied more often on open-access or single-source data. Conclusions: Respiratory virus surveillance and research in Europe have expanded and diversified substantially over the past two decades, particularly after the Coronavirus disease 2019 (COVID-19) pandemic. However, access to advanced and integrated data streams remains uneven across countries. Strengthening preparedness for future respiratory virus threats will require sustained investment in interoperable data infrastructures, improved data governance, and the responsible use of artificial intelligence to integrate heterogeneous data sources.

Background: Talaromycosis and cryptococcosis are prevalent in Southern China and Southeast Asia and are frequently misclassified due to overlapping lesion morphology and limited access to confirmatory testing. Objective: To evaluate the zero-shot diagnostic performance of multimodal large language models in identifying and differentiating cutaneous lesions of talaromycosis and cryptococcosis Methods: Published clinical photographs of cutaneous lesions of talaromycosis and cryptococcosis were systematically retrieved up to 31 August 2025, and seven representative multimodal large language models were benchmarked under a strictly zero-shot setting using a standardized prompt template and a predefined output schema. Latency, unanswerable/invalid response rates, and diagnostic performance were evaluated using accuracy, precision, sensitivity, specificity, F1-score, and Matthews correlation coefficient. For explanation quality assessment, model-generated texts were independently rated by two clinicians across five dimensions, and hallucination events were quantified. Results: In total, 214 articles (95 for talaromycosis and 119 for cryptococcosis), including 244 talaromycosis cutaneous lesion images and 236 cryptococcosis cutaneous lesion images, were collected for zero-shot evaluation. Most models achieved acceptable performance recognition, among them, ChatGPT-5 achieved the best performance. For comprehensive performance comparison, ChatGPT-5 ranked first across six indicators but exhibited relatively lower sensitivity. Evaluation of the output text quality demonstrated that the diagnostic texts generated by GPT-5 were excellent. The EQI was 70.08, with a hallucination rate of 21.76%. Conclusions: ChatGPT-5 demonstrates feasibility in the recognition of cutaneous lesions of talaromycosis and cryptococcosis under zero-shot conditions and can serve as a potential tool for assisting in the analysis of infectious skin disease images.

Background: Task-oriented rehabilitation supported by exoskeletons has the potential to increase therapy intensity, personalization, and accessibility. However, to achieve fully automatic treatment, robotized systems need to analyze therapy in a more complex way than only based on reference trajectories following. Objective: This study investigates the effects of an intelligent, context-aware control algorithm for an upper-limb rehabilitation exoskeleton on patients’ musculoskeletal engagement, compared with constant-admittance robot-assisted therapy and conventional physiotherapist-guided treatment. Methods: A single-session experimental study was conducted with 34 adult participants performing six activities of daily living under three therapy modes: robot-assisted therapy with constant admittance, robot-assisted therapy with an intelligent assist-as-needed algorithm, and physiotherapist-guided therapy. Muscle activity was assessed using surface electromyography of eight upper-limb muscle groups, while joint kinematics were recorded using inertial measurement units. Metrics included EMG power, muscle activation time, joint range of motion, and burst duration similarity indices. Statistical comparisons were performed using the T-test and the Mann-Whitney U-test depending on data normality. Results: Results indicate that the intelligent control strategy engages the musculoskeletal system at least as effectively as constant-admittance control across all exercises. At the same time, more motion control is given to the patient, which is preferable for neuroplasticity training. Compared with physiotherapist-guided therapy, robot-assisted treatment with intelligent control elicited significantly higher and more consistent muscular engagement. Intelligent assistance also modified joint-level motion patterns by reducing compensatory movements, particularly in shoulder–elbow coupling, while maintaining functional task execution. Muscle activation timing patterns during intelligent robot-assisted therapy were more consistent with robotic control than with manual therapy, reflecting altered movement strategies. Conclusions: These findings demonstrate that context-aware, intelligent control in rehabilitation exoskeletons can promote active patient participation, reduce compensatory behaviors, and maintain physiologically meaningful muscle engagement. The proposed approach exceeds the results of recent similar studies, being a promising step toward effective, minimally supervised, task-oriented rehabilitation. Clinical Trial: The experiments were carried out under the KB/132/2024 approval of the Bioethical Committee of the Medical University of Warsaw (https://komisja-bioetyczna.wum.edu.pl/). Written informed consent was obtained from all of the subjects involved in this study.

Background: Early diagnosis, accurate severity assessment of acute pancreatitis (AP), and prediction of progression to severe acute pancreatitis (SAP) are critical. We evaluated an electronic medical record (EMR)-embedded large language model (LLM) for these tasks.
Methods: The LLM reviewed earliest AP hospitalization records of 261 adults and answered three prompts (diagnosis, severity, and risk of progression to SAP).
Results: 224 (85.8%) had mild AP (MAP), 30 (11.5%) moderately SAP (MSAP), and 7 (2.7%) SAP. The LLM diagnosed AP with 89.3% sensitivity and 100.0% positive predictive value (PPV). Severity classification was inconsistent (MAP sensitivity 49.1%, MSAP 66.7%, SAP 42.9%). For progression prediction from initial MAP, the LLM showed high sensitivity (87.5%) but low accuracy (26.8%); Bedside index for severity in acute pancreatitis (BISAP) had higher accuracy (95.5%) but low sensitivity (12.5%). In MSAP, the LLM sensitivity was 85.7% versus BISAP 0%.
Conclusions: An EMR-embedded LLM can detect AP and identify many who progress to SAP, but specificity and severity classification require improvement.

Background: Daily activities shape individuals’ health and well-being, reflecting functioning and lived health. For people with neurological conditions these activities are often disrupted, impacting autonomy and quality of life. Traditional assessments miss subtle, real-time fluctuations, whereas Ecological Momentary Assessment (EMA) captures moment-to-moment activity within natural contexts, offering insight into person-environment-occupation interactions. Despite its growing use, it remains unclear how EMA protocols conceptualize daily activities and integrate person-environment-occupation dimensions in its application for neurological populations. Objective: The aim of this scoping review is to map the existing literature on the use of EMA to capture daily activities, ranging from basic self-care to more complex activities, in individuals with neurological disorders. Methods: A scoping review was conducted, identifying 341 articles, to map studies using EMA to capture daily activities in adults with neurological conditions, with specific focus on content and practical application. Results: Twenty studies using EMA to assess daily activities in neurological populations were included, mostly observational, with two longitudinal studies and two RCTs. Daily activity questions and response formats varied, often using multiple-choice lists; only one allowed open-ended responses. Alongside the daily activity questions additional constructs in the EMA captured person (physical, affective, cognitive), environment (physical, social), and occupation domains, plus motivation and EMA disturbance. Protocols differed in setting, schedule, technology, and adherence, with most reporting completion rates above 70%. Conclusions: Captures daily activities through EMA in neurological populations, shows high adherence despite varied designs, questions, and technologies. The findings indicate that the phrasing of EMA items, the predominance of closed-response formats, and the narrow focus on the verb “doing” limit the depth and nuance of the data collected, often overlooking important aspects of performance and/or engagement in daily activities.

Background: Long-term body weight is regulated by the balance between energy intake and energy expenditure (EE). Although weight stability requires energy balance, achieving and maintaining such balance in everyday life is challenging. Weight loss occurs when EE consistently exceeds energy intake, whereas a sustained positive energy balance promotes weight gain which may lead to obesity. Whole-room indirect calorimetry enables precise 24-h assessment of total EE and its components. Achieving energy balance within a whole-room indirect calorimeter (WRIC) represents a substantial challenge and depends critically on stringent clinical standardization as well as robust technical performance to ensure accurate estimation of energy requirements. Objective: To achieve energy balance within a WRIC and to characterize the technical performance of two newly installed WRIC systems. Methods: Healthy subjects, aged 18 to 65 years with a body mass index of 18.5 to <40 kg/m² are eligible to participate in the study. Resting EE is measured over 30 minutes and combined with the Mifflin–St. Jeor equation to calculate a personalized weight-maintaining diet (WMTD). Participants consume this WMTD for 3 days in free-living conditions before each 24-hour stay in the WRIC. Before and during WRIC stays, participants are instructed to maintain a low physical activity level (PAL≈1.4; PAL defined as 24-h EE/resting EE). Standardized meals (breakfast 8 AM, lunch 1 PM, dinner 6 PM) are provided inside the WRIC. For the first two WRIC stays, biological validation of the system is performed by repeating EE measurements under identical conditions, that is during these stays, the caloric content of the diet matches the pre-calculated WMTD adjusted for reduced physical activity within the WRIC. For a third WRIC stay, following another 3-day WMTD run-in, the caloric content of the diet is matched to each participant’s average 24-h EE from the two preceding stays and energy balance is calculated. Hereupon, two additional WRIC stays are conducted after another 3-day WMTD run-in and participants are instructed to achieve a higher physical activity level (PAL≈1.7) using cycle ergometry. During the first stay within the WRIC with PAL≈1.7, caloric content of the diet equals the WMTD adjusted for PAL≈1.7. For the following 24-h EE assessment with PAL≈1.7, diet is adjusted such that its caloric content equals the previously measured 24-h EE under increased physical activity and energy balance is reassessed. The day after the last 24-h EE assessments with PAL≈1.4 and PAL≈1.7, respectively, ad libitum energy intake is measured using a buffet to relate individual EE with energy intake. Body weight is monitored throughout the study. Results: The trial commenced in August 2025. At the time of manuscript submission, six participants have been enrolled. Based on prior data, a total of 34 participants is required to evaluate the improvement in mean energy balance by 100 kcal with a power >0.80, assuming a standard deviation of 200 kcal. The final analyses will include energy balance, changes in body weight, components of EE, ad libitum energy intake, and circulating hormones involved in appetite regulation and satiety. Conclusions: This trial evaluates whether energy balance can be achieved during repeated stays in a WRIC and provides a detailed assessment of the performance of two newly installed WRIC systems.

Background: Background: Artificial Intelligence (AI) is rapidly transforming healthcare by reshaping clinical decision-making, service organization, and professional competencies. In physiotherapy, AI offers opportunities to enhance efficiency, personalization, and interdisciplinary collaboration, while also posing ethical, educational, and governance challenges. Objective: Objective: This study aimed to examine physiotherapists’ perceptions of AI implementation across professional domains, identifying strengths, weaknesses, opportunities, and threats (SWOT), and to assess the influence of prior AI experience and knowledge levels on these perceptions. Methods: Methods: An observational, cross-sectional survey was conducted using a 26-item online questionnaire structured within a SWOT framework. The survey included demographic data, 20 Likert-scale items, and two open-ended questions. Composite indices for Opportunities and Concerns were calculated, internal consistency was assessed with Cronbach’s α, and non-parametric tests with false discovery rate adjustment were applied. Qualitative responses were thematically analyzed. Results: Results: Fifty physiotherapists participated, most reporting basic or no AI knowledge, while 52% had prior AI experience. The Opportunities Index showed excellent internal consistency (α = 0.93) and the Concerns Index acceptable consistency (α = 0.77). Overall, Concerns outweighed Opportunities (3.68 vs. 3.31). Main concerns included reduced human contact, insufficient training, and data privacy, while key opportunities involved administrative automation, training in emerging technologies, and interdisciplinary collaboration. Prior AI use was associated with greater concern about data privacy. Conclusions: Conclusions: Physiotherapists view AI as a promising yet challenging innovation. Strengthening digital literacy, ethical oversight, and participatory governance is essential to ensure AI adoption aligns with human-centered physiotherapy care.

Background: Cardiovascular disease remains the leading global cause of mortality, driven by interrelated behavioral, biological, and psychosocial risk factors despite the availability of effective prevention and treatment strategies. Persistent policy inertia, systemic fragmentation, and adverse social and commercial determinants have limited national responses. Addressing these gaps necessitates place-based, systems-oriented approaches that mobilize local assets, engage multi-sector stakeholders, and incorporate adaptive evaluation. The Springfield Healthy Hearts initiative exemplifies such an approach by positioning Greater Springfield as a “living laboratory” for coordinated cardiovascular health action through a comprehensive data framework, providing a replicable model for other communities. Objective: This protocol outlines the Springfield Healthy Hearts Data Framework; a multi-component system for dynamically guiding, implementing and evaluating coordinated action for heart health. Methods: The Data Framework was developed through a structured co-design process involving community members, expert researchers, health professionals, and representatives from local implementation partners. The framework comprises four integrated components: (1) Project Evaluations, applying pragmatic frameworks to assess coordinated action projects; (2) Community Evaluation, a repeated cross-sectional evaluation of Springfield residents, workers and regular visitors to capture individual-level behavioural, biological and psychosocial CVD risk factors, as well as engagement with coordinated action projects; and (3) City Evaluation, ongoing monitoring of suburb- and city-level indicators across four domains: sociodemographic characteristics, built environment, food and commercial environment and health services. (4) Data Synthesis, to utilise data across all levels to inform a continuous learning system.
Project evaluations will use both quantitative and qualitative methods, including realist evaluation where appropriate. Community evaluation will be analysed using descriptive statistics, mixed-effects models and subgroup analyses, with missing data addressed via multiple imputation. City-level data will be analysed descriptively and dynamically to detect temporal trends and contextual changes. Results: As of February 2026, we have held two Data Framework co-design workshops with 15 community members. Their input, priorities and needs have informed our framework’s components. Conclusions: The Springfield Healthy Hearts Data Framework is a replicable model for other communities aiming to implement city-wide, coordinated approaches to heart health action. Findings will be disseminated through peer-reviewed publications, community reports, interactive dashboards, and policy briefs.

Background: Breast Cancer (BRCA) is the leading cause of death in females worldwide. Although progress in mammography-based screening, the diagnosis of BRCA remains a challenge. However, the sensitivity decreases with high breast density of mammography and a high level of heterogeneity with different prognoses are necessary to improve prognosis in BRCA patients. The valuable molecular targets and therapeutic biomarkers improve the prognoses of BRCA patients, leading to a lower incidence of recurrences. Objective: This report is conductive to provide new ideas for the clinical potential diagnosis and treatment of BRCA. Methods: The transcriptome and methylation genes were downloaded from The Cancer Genome Atlas (TCGA) database. Methyl Mix algorithm was performed to obtain methylation-driven genes. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were applied for identification of methylation-driven genes with functional enrichment. After screening clinical data, a risk score model was established based on univariate and multivariate cox regression analyses. The risk evaluation model was performed using the Kaplan-Meier (K-M) methods, Receiver Operating Curves (ROC) and Area Under Curve (AUS). Overall survival analysis of methylation-driven genes was used survival R package. The analysis of gene methylation and gene expression was conducted to explore the relationships in BRCA. Results: A total of 1213 samples from TCGA database. 153 differentially expressed methylation-driven genes were obtained. 6 methylation-driven genes (GYPC, KCNH8, USP44, ZNF502, ZNF677, and ZSCAN23) were significant negative correlations between methylation and gene expression levels. Functional analysis suggested that methylation-driven genes enriched in mammary gland development and prolactin signaling pathway. The expression of 9 methylation genes (ADHFE1, KNSTRN, BUB1B, ABCB1, QKI, NDST4, CKMT1B, GALNT8, and GLT1D1) was differently profiled from two groups related to clinical information. The ROC (AUC=0.703) indicated that risk score (P＜0.001) showed accuracy for predicting models. The univariate and multivariate cox regression analysis demonstrated age (P＜0.001) was an independent prognostic factor for patients with BRCA. Methylation and gene expression analysis were identified that ALDH1L1-AS2-1, PTPRZ1-1, and UBE2T-1(P＜0.05) independently predicting prognosis in BRCA patients. Conclusions: Our study suggested that ALDH1L1-AS2-1, PTPRZ1-1, and UBE2T-1 might as predictors of great clinical potential biomarkers in BRCA. These results will provide new ideas for the clinical treatment of BRCA patients.

Background: Digital physical exercise interventions offer a scalable solution to combat age-related cognitive decline. While various modalities exist, their comparative effectiveness across different cognitive domains remains unclear, necessitating a systematic evaluation to guide clinical practice. Objective: This study aims to evaluate and rank the comparative effectiveness of different digital physical exercise interventions—including immersive VR (IVR_E), non-immersive exergames (NI_ExG), remote exercise (RE), and VR combined with cognitive training (VR_EC)—on global cognition, executive function, and memory function in older adults. Methods: We conducted a systematic review and Bayesian network meta-analysis of randomized controlled trials (RCTs) published between January 1, 2010, and April 30, 2025. Data sources included PubMed, Embase, and Web of Science. Eligible studies involved older adults (aged ≥60 years) and compared digital physical exercise interventions against routine interventions (RI) or non-intervention (NI). The primary outcomes were global cognition, executive function, and memory function. We estimated standardized mean differences (SMDs) and ranked interventions using the surface under the cumulative ranking curve (SUCRA). Results: A total of 41 RCTs involving 2919 participants were included. For global cognition, IVR_E emerged as the most effective intervention (SUCRA=96.6%), followed by NI_ExG (SUCRA=76.4%); both modalities were significantly superior to RI. Regarding executive function, RE (SUCRA=73.8%) and NI_ExG (SUCRA=69.3%) ranked highest. Notably, NI_ExG was the only intervention to demonstrate a statistically significant improvement over RI in this domain, while IVR_E showed no significant advantage. For memory function, IVR_E was the dominant intervention (SUCRA=82.8%) and was the only modality significantly more effective than RI. Subgroup analyses further indicated that a cumulative training dose exceeding 1000 minutes is critical for observing significant improvements in memory function. Conclusions: Digital physical exercise interventions significantly enhance cognitive function in older adults, but their optimal application is domain-specific. IVR_E appears most effective for global cognition and memory, likely due to high immersion and standardization. Conversely, NI_ExG and RE are preferable for enhancing executive function, potentially offering more scalable alternatives for home-based care. Future interventions targeting memory improvement should ensure sufficient cumulative training duration. Clinical Trial: PROSPERO CRD42025103014

Background: Assistive technologies can support independent living among older adults, but uptake is often constrained by attitudes and confidence. The COVID‑19 lockdowns accelerated technology use across all age groups, offering a natural experiment to examine changes in adoption. Objective: This study aimed to examine changing patterns of technology use in older adults, to provide insight as to how service providers can support the use of technology to support independence and well-being. Methods: Two cross‑sectional surveys were conducted in UK retirement villages, one before the pandemic (2020) and one after lockdowns (2023), to assess technology attitudes and use. Semi‑structured interviews with eight participants in a technology trial scheme provided qualitative insights. Results: Technology adoption increased significantly between 2020 and 2023, with older adults reporting greater confidence and comfort in digital use. Self‑education and informal support from family or friends were the most common pathways to adoption. Age‑related differences in confidence observed in 2020 were no longer apparent in 2023, although gender disparities persisted. Interviewees emphasized usefulness and accessibility as key drivers of sustained engagement. Findings demonstrate that the pandemic catalyzed lasting increases in technology adoption among older adults, including increased confidence and ownership. Conclusions: Findings demonstrate that the pandemic catalyzed lasting increases in technology adoption among older adults, including increased confidence and ownership. These results provide evidence for housing providers and policymakers to embed accessible technologies and targeted support in retirement communities, thereby enhancing independence and quality of life in later life.

Social media influencer marketing is a digital advertisement strategy that is growing in popularity. Its use has been documented in consumer purchasing behavior but is yet to be described for clinical trial recruitment. In this tutorial, we describe the steps we followed to develop and deploy a social media influencer advertisement for the recruitment of participants into the Groceries for Residents of Southeastern USA to Stop Hypertension (GoFreshSE) trial. We also provide a preparation framework for other studies who would like to use this modality for their own clinical trial recruitment. We used Cameo Business to identify potentially relevant influencers to hire by selecting influencers who were popular in the 3 geographic areas from which GoFreshSE is recruiting. We narrowed down the list of possible influencers by selecting those with ≥100,000 followers on their respective social media platforms (for a wide reach) and charged a cost of ≤$3,000/video. We ultimately selected a former football coach, who provided a high-quality video of him reading an institutional review board-approved script 4 days later. We utilized open source, commercially available tools to edit the video and deployed the 44-second-long video on Facebook and Instagram using Meta’s Advertising platform. Social media influencer marketing through the Cameo Business platform is a rapid mechanism to develop clinical trial influencer recruitment videos.

Background: Sample pooling is an essential strategy for optimizing polymerase chain reaction (PCR) resources during infectious disease outbreaks, especially in the beginning. While high-dimensional hypercube pooling strategies—such as those recently highlighted in Nature—offer superior efficiency in low-prevalence settings, they are difficult to implement in practice. The human cognitive and physical limitation to three-dimensional environments makes manual execution of four- or five-dimensional sample arrays prone to significant operational error. Objective: To develop and evaluate a novel "Ternary Card Hypercube Pooling" strategy that simplifies the implementation of multidimensional pooling, making it accessible for laboratory personnel without compromising mathematical efficiency. Methods: We integrated logic from ternary card games (based on sets of three attributes) to create a visual and physical framework for hypercube pooling. This method maps high-dimensional coordinates onto a simplified "card" system, allowing laboratory technicians to organize and track samples using intuitive pattern recognition rather than complex multidimensional mapping. Results: The Ternary Card method successfully translates the efficiency of hypercube pooling into a user-friendly workflow. It maintains the high performance of traditional hypercubic algorithms—allowing for rapid identification of positive samples in a single step in the majority of cases—while significantly reducing the risk of manual pipetting errors and the need for specialized automated equipment. Conclusions: The Ternary Card Hypercube Pooling strategy bridges the gap between theoretical mathematical efficiency and practical laboratory application. By reducing the complexity of sample handling, this method provides a scalable solution for increasing PCR throughput in response to future pandemics, particularly in resource-limited settings. Clinical Trial: NA

Background: Based on its nature, cyberbullying is expected to be frequent and prevalent because of the continuity in technological advancement over time. This change results in more victims and is challenging to detect, negatively impacting their health. Given that adolescents in Jordan face a high rate of cyberbullying, it is essential to understand how this experience affects them. Objective: Objective: the current study sought to explore individual experiences and perspectives on cyberbullying victimization among adolescents to intervene and reduce future incidences of cyberbullying. Methods: Method: The analysis was based on a cross-sectional study investigating cyberbullying and its mental health consequences among 400 students between the ages of 14 -17 from public schools in central and northern Jordan. Those respondents were asked to answer three open-ended questions describing their experiences with cyberbullying if they experienced cyber victimization as either victims or bully-victims, resulting in 240 responses. Thematic analysis was then used to interpret patterns of shared meaning across participants' narratives related to cyberbullying experiences in cyberspace. Results: Results: three key themes and several subthemes emerged from this study: (a) effects of cyberbullying, (b) challenges in overcoming its consequences, and (c) elements influencing the severity of cyberbullying experiences. Conclusions: Conclusion: the findings offer valuable insights for creating safer online environments and reducing cyberbullying’s psychological and social harms through appropriate interventions.

Background: Artificial intelligence (AI) has reached expert-level performance across many areas of medical imaging, yet this progress has not translated proportionally into improvements in patient outcomes. While deep learning models excel at pixel-level pattern recognition, their impact on clinical decision-making, workflow efficiency, and patient-centered care remains poorly characterized Objective: This structured narrative review synthesizes evidence from high-quality studies (2018–2025) to evaluate whether imaging AI systems meaningfully improve patient outcomes beyond diagnostic accuracy. The review critically examines clinical integration, workflow implications, ethical considerations, and the persistent gap between algorithmic performance and patient-centered benefit. Methods: A structured search of PubMed, Scopus, IEEE Xplore, and Web of Science (2018–October 2025) identified empirical studies applying AI to human medical imaging and reporting both diagnostic metrics and real-world clinical, workflow, or patient-centered outcomes. Studies were screened independently by two reviewers, and data were extracted using predefined categories : model type, dataset characteristics, validation strategy, performance metrics, workflow impact, patient outcomes, and ethical considerations. Results: Ten high-quality studies met the inclusion criteria. Across domains (ophthalmology, mammography, echocardiography, CT, PET/CT, and chest radiography), AI models achieved strong diagnostic performance (pooled mean AUC = 0.91 ± 0.03). However, only 30% of studies reported measurable patient impact and 20% reported workflow improvements. External validation often revealed 5–10% performance degradation, and only four systems were deployed in routine care. Ethical analyses showed emerging concerns regarding bias, explainability, and trustworthiness particularly related to racial inference from imaging data. Conclusions: Medical imaging AI has matured algorithmically but remains clinically immature. Achieving true patient-centered benefit requires shifting from model-centric development to systems-level innovation: multimodal integration, explainable AI, human-in-the-loop designs, equity-aware training, and prospective clinical evaluation. AI will advance from “seeing the organ” to “understanding the patient” only when technical performance aligns with clinical workflows, ethical oversight, and human experience.

Background: Intelligent technologies are transforming healthcare delivery, necessitating that nursing curricula prepare students for digitally enhanced practice environments. However, empirical evidence examining nursing students' readiness for technology adoption, particularly through established theoretical frameworks, remains limited in Middle Eastern educational contexts. Objective: The objectives of this study were to (1) assess the level of awareness among nursing students regarding the use of artificial intelligence (AI) applications in nursing education; (2) examine nursing students' perceptions of the potential benefits and challenges associated with AI adoption, guided by the core constructs of the Unified Theory of Acceptance and Use of Technology (UTAUT); and (3) evaluate nursing students' readiness and preparedness for artificial intelligence adoption by analysing the relationships between UTAUT-based theoretical constructs and behavioural intention to use AI technologies in educational and clinical training contexts. Methods: A cross-sectional survey was conducted among 314 undergraduate nursing students at a university in the United Arab Emirates. Data were collected using a validated questionnaire (Cronbach α=.89; content validity index=0.92) measuring UTAUT constructs including performance expectancy, effort expectancy, social influence, facilitating conditions, and behavioural intention. Analysis utilized IBM SPSS Statistics version 28.0, including descriptive statistics, Pearson correlation, and multiple regression Results: Students demonstrated high awareness (298/314, 94.9%) and training interest (261/314, 83.1%), with favourable perceptions of artificial intelligence's educational benefits. However, practical confidence remained lower (186/314, 59.2%), and three-quarters indicated needing substantial support. Performance expectancy (mean 3.96, SD 0.72) and facilitating conditions significantly predicted behavioural intention. The regression model explained 58% of variance in behavioural intention (R²=0.58; F6,307=71.24; P<.001). Performance expectancy emerged as the strongest predictor (β=.38; P<.001), followed by social influence (β=.20; P<.001) and effort expectancy (β=.19; P=.001). A pronounced gap emerged between theoretical readiness (mean 3.78-4.09) and actual preparedness (mean 2.00-2.56), with insufficient training (mean 2.03, SD 0.76) and limited practical experience (mean 2.13, SD 1.34) as primary deficits. Conclusions: The Extended UTAUT framework effectively explained nursing students' artificial intelligence adoption intentions. While students demonstrate positive attitudes, the readiness-preparedness gap highlights urgent needs for structured competency development, faculty training, and phased implementation strategies in nursing education.

Background: Enhancing telemedicine requires a clear understanding of how avatars influence medical collaboration. The ArtekMed study group developed a MR teleconsultation system that enables a remote expert (VR user) to interact in real-time with a local augmented reality (AR) user within a shared working space. The system was compared to a standard video call system in five randomized cross-over trials in a healthcare simulation center. Objective: This post-hoc study investigates user’s perceptions of a virtual character representing a remote expert across four real-time mixed-reality (MR) teleconsultation scenarios. Methods: A total of 56 medical professionals participated as AR users collaborating with a remote expert represented by a virtual character. A post-hoc qualitative analysis of structured post-session interviews was performed to explore participants’s perceptions of the avatar, focusing on perceived helpfulness, visual design and user engagement. Results: Overall, most participants did not perceive the avatar as helpful for task execution in procedural scenarios and frequently described it as unnecessary or even distracting. In contrast, in more complex and demanding scenarios, such as emergency craniotomy planning or intensive care treatment of patients with acute respiratory distress syndrome, some participants perceived the avatar as providing mentorship, guidance and psychological support. These findings suggests that while avatars may offer limited perceived value in task-focused medical collaboration, they may support user engagement in scenarios requiring sustained interaction and social presence. Conclusions: The results align with existing literature indicating that the impact of avatars is context dependent. In mixed-reality environments, where virtual character coexists with real-world reconstructions, avoiding behavioral incongruence and uncanny effects may be more critical than achieving high visual fidelity. Future research should prospectively explore how different levels of avatar abstraction and fidelity influence collaboration in MR telemedicine.

Background: Anxiety and depressive disorders remain highly prevalent and insufficiently treated, with many individuals experiencing persistent or untreated symptoms, limited access to evidence-based care, or insufficient support between clinical encounters. Adults with disabilities represent a particularly underserved sub-population, often facing compounded barriers to mental health care and higher rates of anxiety and depression. Digital therapeutics offer a scalable opportunity to address these gaps by extending structured, evidence-based interventions beyond traditional care settings. Objective: The current pilot study evaluated Rauha™, a novel digital therapeutic that integrates cognitive behavioral therapy (CBT)-based modules with live weekly sessions led by a National Board-Certified Health and Wellness Coach (NBC-HWC), delivering structured, smartphone-based psychoeducation and interactive therapeutic exercises combined with personalized mental health coaching supporting behavior change. Methods: Thirteen adults with mobility and/or hearing disabilities and clinically elevated anxiety and/or depression were enrolled in a single-arm, within-subjects design. Participants completed eight weeks of CBT modules delivered via smartphone, accompanied by synchronous virtual mental health coaching. Anxiety and depression were assessed using the Hamilton Anxiety (HAM-A) and Hamilton Depression (HAM-D) Rating Scales, respectively, at baseline, post-treatment, and at four-week follow-up. Results: Mean reductions were significant for both anxiety (-13.05 ± 2.51, P < .001) and depression (-12.83 ± 1.55, P < .001), exceeding thresholds for clinical significance and sustained through follow-up. At post-treatment, 84.6% of participants showed clinically significant improvement in both anxiety and depression. At follow-up, 76.9% and 92.3% of participants showed clinically significant improvement in anxiety and depression, respectively. Between baseline and follow-up timepoints, these reductions corresponded to mean shifts from moderate to mild anxiety on the HAM-A and moderate to mild/non-depressed on the HAM-D. Participants reported strongly favorable acceptability, experience, and usability ratings for the Rauha™ treatment program, demonstrating 100% treatment retention and an average 5.5 replay rate of personalized smartphone content. Conclusions: Findings demonstrate that a combined digital CBT and NBC-HWC approach can yield clinically meaningful and durable symptom reductions in depression and anxiety, coupled with high user acceptability and engagement, for adults with disabilities. These findings provide preliminary evidence supporting Rauha™ as a scalable, evidence-informed mental health intervention with strong potential to improve access and address key barriers to care.

Background: Recent advances in machine learning enable fully automated pattern recognition and representation learning directly from biomedical signals, offering an alternative to handcrafted, task-specific ECG algorithms. However, demonstrating that such approaches can achieve clinically reliable performance remains challenging due to the limited availability of representative, expert-annotated ECG datasets. In the context of shockable rhythm detection, research is largely constrained to a small number of publicly available databases with limited cohort sizes and annotation inconsistencies. Shockable rhythm detection during sudden cardiac arrest represents a clinically critical and well-defined use case for evaluating the robustness of automated ECG representation learning. Objective: This study aimed to assess whether a deep learning framework with fully automated ECG feature extraction can accurately and reliably classify cardiac conditions, using shockable rhythm detection as an example application, and to evaluate the impact of expert reannotation on model performance. Methods: Four public arrhythmia databases (MIT-BIH Arrhythmia Database, Creighton Ventricular Tachycardia Database, MIT-BIH Ventricular Arrhythmia Database, and American Heart Association Database) were used. ECG waveforms were transformed into spectrograms and analyzed using residual neural networks (ResNets). A balanced dataset of 60,340 augmented 3-second segments was generated to optimize model architecture. The final model (ResNet32) derived shock decisions from blocks of three consecutive 3-second segments, corresponding to a 9-second evaluation window. Performance was assessed using leave-one-subject-out cross-validation on the original, non-augmented dataset. All misclassified blocks were independently reviewed and reannotated by expert cardiologists. Results: Across 19,802 evaluated blocks (2,495 shockable), the model achieved an accuracy of 99.68%, sensitivity of 99.63%, and specificity of 99.69%. Expert review revealed that 73% of misclassified blocks differed from the original database annotations. After incorporating expert annotations, performance improved to 99.92% accuracy, 99.76% sensitivity, and 99.87% specificity. Conclusions: This study demonstrates that a deep learning framework with fully automated ECG representation learning can achieve highly accurate classification of shockable rhythms. The algorithm design, including spectrogram-based representation learning and block-based decision-making, promotes clinical robustness by incorporating temporal context, reducing sensitivity to transient rhythms, and mitigating the impact of annotation inconsistencies while aligning with clinical assessment practices. Beyond shockable rhythm detection, the proposed approach has the potential to support automated analysis of additional cardiac conditions, such as QT prolongation and electrolyte imbalances, and to contribute to the generation of standardized, clinically representative, and expert-annotated ECG databases. Such capabilities may facilitate more reliable benchmarking and support future translation of automated ECG analysis into real-world clinical and mobile applications.

Background: Although effective, current CAR-T production methods — centralized, manual, and complex — are cost-intensive, time-consuming, and prone to variability. AIDPATH proposes a decentralized, automated alternative that integrates patient-specific data, optimizes resource use, and potentially improves cell viability, manufacturing efficiency, and patient outcomes. Objective: The aim of this study was to compare AIDPATH-produced CAR-T therapy to both Cilta-Cel and standard of care (SoC) for triple-class refractory multiple myeloma (MM) patients, over a 40-year time horizon in Germany from the hospital perspective. Methods: A partitioned survival model reflecting 3 health states (progression-free disease, progressed disease, and death) was used. The analysis used clinical trial data for Cilta-Cel, real-world data for SoC, and estimated parameters for AIDPATH, due to the developmental status of the platform. The primary outcome was the incremental cost effectiveness ratio, secondary outcomes included sensitivity and scenario analyses. Results: AIDPATH was dominant compared to both Cilta-Cel and SoC. Most costs for CAR-T therapies were driven by acquisition and adverse events. Sensitivity analyses showed the results were most influenced by discount rates and assumptions about progression-free survival. Scenario analyses, including reduced adverse events and shorter vein-to-vein time for AIDPATH, further supported its cost-effectiveness. Conclusions: This is the first study to assess the cost-effectiveness of CAR-T product generated with AI support in Germany from the hospital perspective. AIDPATH was found to be a cost-effective alternative to both Cilta-Cel and SoC, making it a promising option for future implementation. While further data are needed, this study provides valuable guidance for health care stakeholders, reimbursement discussions, and future research.

Background: Atrial fibrillation (AF) is a significant contributor to cardioembolic stroke, necessitating early and precise detection of AF to mitigate associated risks. Long-term Holter electrocardiography (ECG) monitoring using garment-type wearable devices produces large volumes of single-lead data with various noise artifacts. Deep learning has achieved high performance in AF detection from ECG data; however, many deep learning studies report strong performance on curated datasets or noise-controlled recordings. Comparatively fewer approaches have been developed and evaluated with an explicit strategy to maintain diagnostic accuracy in noise-included real-world wearable Holter ECG data. An alternative representation using the R–R interval (RRI) time series may reduce the dependence on waveform morphology and provide a computationally efficient pathway for robust AF screening in noisy recordings. Objective: This study aims to develop a computationally efficient, noise-robust deep learning model that leverages the irregularity of the RRI in noisy wearable monitoring environments. We evaluated the impact of the analysis window length on model performance. Methods: Single-lead Holter ECG data from 117 patients at the University of Osaka Hospital were analyzed, excluding those with atrial tachycardia/flutter. The RRIs were extracted, segmented into 1.5-, 3-, and 6-min windows, and transformed into two-dimensional histogram images. A ResNet-34–based two-dimensional convolutional neural network (2D-CNN) was trained for three-class classification. The model performance was evaluated using five-fold inter-patient cross-validation and externally validated using the MIT-BIH AF Database. Patient-level AF burden was defined as the proportion of AF duration relative to total analyzable recording time per patient; agreement between cardiologist-derived and model-estimated AF burden was assessed using Pearson’s correlation coefficient and linear regression. Results: Of 129 monitored patients (Feb 1, 2023–Nov 20, 2025), 117 were analyzed. In the internal validation, the 3-min window had superior performance (accuracy, 96.9%; AF sensitivity, 97.0%; AF specificity, 98.2%). External validation corroborated this balance (accuracy, 96.1%; AF sensitivity, 93.3%; and AF specificity, 98.7%). The 3-min model exhibited an exceptionally high correlation with the reference AF burden (r = 0.988, R² = 0.976). Conclusions: The RRI-based 2D-CNN achieved high AF classification accuracy and excellent agreement with AF burden. By utilizing RRI features and a noise-adaptive training strategy, a 3-min RRI window has emerged as a practical solution for efficient AF screening in a garment-type Holter ECG.

Background: Health facilities globally face increasing operational pressure from rising Communicable and Non-Communicable disease burdens, with low- and middle-income countries experiencing the greatest challenges. To improve operational efficiency, the timely identification of healthcare use patterns and recurring care needs is essential. Objective: This study aimed to develop machine learning (ML) models that predict (1) patient revisits within 30, 90, and 180 days and (2) the most likely diagnosis at revisit, using longitudinal national health insurance scheme (NHIS) claims data from a medical facility in Ghana. Methods: We conducted a retrospective cohort study using electronic health records (EHR) spanning January 2015 to August 2025. The analytical dataset comprised 111,488 visits from 34,486 unique patients. We compared five machine learning approaches: logistic regression (LR), random forest (RF), extreme gradient boosting (XGBoost), multilayer perceptron (MLP), and TabM (a recent parameter-efficient ensemble architecture for tabular data). Patient-level data splitting prevented information leakage between training and evaluation sets. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC-ROC), accuracy, and top-3 accuracy for multiclass disease prediction (31-54 categories depending on horizon). Feature importance was assessed using Shapley Additive exPlanations (SHAP) analysis for XGBoost and permutation importance for TabM. Results: For revisit prediction, TabM achieved the highest AUC-ROC across all horizons (0.891 at 30 days, 0.942 at 90 days, 0.973 at 180 days), followed closely by XGBoost (0.884, 0.927, 0.964). Disease prediction proved more challenging given the multiclass nature of the task; TabM achieved the highest top-3 accuracy (0.420 at 30 days, 0.626 at 90 days, and 0.635 at 180 days) and standard accuracy for 90 and 180 days, respectively (0.494 and 0.492), while XGBoost achieved the highest AUC-ROC (0.666, 0.710, and 0.690). Feature importance analysis revealed that clinical visit pattern features (total visits, visit frequency) dominated revisit prediction, while demographic features (age) and current diagnosis drove disease prediction. Conclusions: Machine learning models using NHIS claims data can effectively predict hospital revisits and narrow diagnostic possibilities to clinically useful shortlists in a resource-limited hospital setting. TabM, a recent tabular deep learning architecture, has demonstrated competitive or superior performance compared to gradient boosting methods, challenging assumptions about the limitations of neural networks on tabular healthcare data. These findings support the feasibility of deploying predictive analytics in Sub-Saharan African health systems with modest data infrastructure.

Background: Despite increasing technical maturity, most clinical artificial intelligence (AI) systems remain confined to pilot or experimental settings, rarely achieving sustained integration into routine healthcare delivery. The persistence of this "pilot trap" is driven primarily by structural and institutional constraints rather than algorithmic performance limitations. Objective: To develop a governance framework that enables the transition of clinical artificial intelligence (AI) from project-based experimentation to durable institutional infrastructure, informed by the establishment of a provincial-level AI platform within a policy-oriented healthcare system in China. Methods: An 18-month real-world institutionalization process of the Hebei Provincial Clinical AI Platform was examined, encompassing the formation of a dedicated Medical AI laboratory, designation as a provincial engineering center, acquisition of regulatory authorizations, and deployment of structured clinical application pathways. Framework construction was grounded in systematic analysis of governance arrangements, policy legitimacy mechanisms, and translational implementation trajectories observed throughout the institutionalization process. Results: The framework comprises six interdependent modules encompassing institutional carrier formation, data and computational infrastructure, ethical and regulatory governance, interdisciplinary operational coordination, translational scaling and regional dissemination, and continuous evaluation. Implementation evidence indicates that governance architecture functions as a prerequisite to, rather than a consequence of, technical deployment. Organizational anchoring, external legitimacy, and coordinating capacity enable AI systems to operate as enduring institutional infrastructure rather than transient technological experiments. The framework reframes clinical AI from an algorithmic artifact to an embedded institutional capability, redirecting implementation logic from technical performance metrics toward governance maturity. Conclusions: Sustainable clinical AI implementation is associated with governance-first rather than technology-first strategies. Effective institutionalization requires the concurrent establishment of organizational ownership, policy legitimacy, and coordinating mechanisms prior to large-scale deployment. Although derived from a policy-oriented healthcare context in China, the core governance functions demonstrate potential transferability across health systems, with institutional mechanisms varying by context while functional requirements remain comparatively stable. The framework offers an operational architecture for health systems seeking AI as infrastructure rather than episodic experimentation. Clinical Trial: NA.

Background: Auditory discrimination training is widely used to supplement aural habilitation and rehabilitation in individuals with hearing or auditory challenges. Recently, gamification has been introduced to enhance attention and engagement during training Objective: In this study, we developed and compared two pure-tone auditory discrimination training systems: a game-based system with dual-task gamified activities and a non-game-based control system with identical auditory tasks but without gamified elements. Methods: A three-stage process (design, implementation, and evaluation) yielded beta versions of both systems. In the evaluation stage, eleven young adults (18–30 years) completed usability, user experience, and engagement questionnaires after using each system. Behavioral performance was assessed through mean response time, proportion of correct responses, Weber fraction, the Inverse Efficiency Score, and a novel Auditory Discrimination Performance Index. Results: The game-based system produced significantly higher scores in focused attention, aesthetic appeal, reward, attractiveness, stimulation, and novelty questionnaires’ perceived domains while no significant differences were found in most of auditory discrimination performance metrics. Conclusions: These findings suggest that gamification can substantially improve user experience and engagement without degrading short-term discrimination performance. Longitudinal studies are needed to determine whether these experiential advantages translate into long-term auditory training benefits and how sound features may improve performance in other auditory tasks.

Background: Co-design ensures cultural safety of health interventions for Aboriginal and/or Torres Strait Islander communities. However, an intervention developed with one Indigenous community may not be suitable for another geographically and culturally distinct community. Objective: This study aimed to culturally adapt content and features of a mobile health (mHealth) application co-created by communities in one Australian state to better meet the needs of mothers and caregivers of Aboriginal and/or Torres Strait Islander children aged 0-18 years and health professionals in another state. Methods: The study followed the stages of the cultural adaptation stepwise model by Barrera et al. Mothers/caregivers of Aboriginal and/or Torres Strait Islander children aged 0-5 years and their health professionals were recruited from multiple community sites. Data were collected through culturally appropriate yarning circles or interviews facilitated by Aboriginal research staff. Qualitative data were transcribed and inductively analysed to generate themes. The feedback was translated into practical changes that were applied to the mHealth application. Results: Data saturation was achieved after yarning circles with 21 women and seven health professionals. Nine themes were generated from mothers/caregivers’ data: 1) cultural relevance and sensitivity, 2) linking with culturally appropriate services, 3) Use of lay language and more audio-visual content , 4) concerns with mobile data usage, 5) Perceptions about the current content of the Jarjums app, 6) raising children, 7) safety, 8) health and wellbeing of mothers and caregivers, and 9) coordinating health care. Four themes were generated from data collected from health professionals: 1) favourable features of the app, 2) potential barriers to the use of the app, 3) healthcare system access issues, and 4) recommended modifications.
Based on feedback received, the mHealth application changes included the addition of information on healthy relationships and raising children, more visual content, and localized service directories for different categories of care and support. Conclusions: A co-designed, culturally sensitive mHealth application is likely to support Aboriginal and/or Torres Strait Islander families facing health disparities due to disruption of Indigenous culture by a foundation for a potential clinical trial for effectiveness evaluation and wider implementation.

Background: Quality of Life (QoL) questionnaires are an established instrument designed to assess overall wellbeing and quality of life of patients. They are important in predicting the outcome of the disease and understanding the needs of individual patients. However, their repeated collection imposes substantial burden on both patients and clinical professionals. Many patients seek emotional support and mutual exchange in online communities for peer-support, where they frequently share detailed descriptions of symptoms and treatment experiences, addressing topics covered in QoL questionnaires. The emergence of large language models (LLMs) uncover potential for automatic extraction of relevant QoL information from patient-generated text. Objective: The aim of this study is to evaluate and compare various open-source LLMs and optimization approaches for automated extraction of QoL information from forum posts. Methods: The dataset consisted of 2,683 English-language posts from breast cancer patients recruited on Inspire.com online communities, manually annotated with sentence-level text spans indicating whether and where posts contained information relevant to 53 QoL questions from EORTC QLQ-C30 and QLQ-BR23 questionnaires. 11 open-source LLMs (8B-70B parameters) were evaluated in a zero-shot setup, generating 4,452 post-question predictions per model under two input conditions: post-only and post with additional context. For the best-performing model, additional experiments assessed the impact of chain-of-thought prompting, instruction optimization, few-shot prompting and parameter-efficient fine-tuning. For correctly classified yes/no instances, the overlap between model-generated evidence and human-annotated spans was evaluated. Results: Across 11 evaluated LLMs, GPT-OSS 20B achieved the highest macro F1-score (0.79) in the zero-shot post-only setting. Providing additional context consistently reduced performance of all models. Model size did not correlate with F1-score, with several mid-sized models (14B-30B) outperforming 70B models. For GPT-OSS 20B, chain-of-thought prompting did not improve performance (0.77). Instruction optimization produced results similar to the baseline in both zero-shot and few-shot settings (0.78-0.80). Bootstrap few-shot prompting with random search achieved the highest score overall (0.81). Parameter-efficient fine-tuning decreased performance (0.71). Most classification errors occurred in semantically broad or ambiguous terms and the fallback question. For correctly predicted yes/no answers, model-generated evidence matched or partially matched human-annotated spans in 89% of cases. Conclusions: Open-source LLMs are a promising tool for extracting QoL information that aligns with standardized questionnaire responses from online health forums. Mid-sized models achieved the highest accuracy, particularly in zero-shot, post-only settings. Few-shot prompting can further improve the results. Models were also able to generate evidence spans that closely matched human annotations. However, they consistently struggled with ambiguous and semantically overlapping terms. Overall, automated extraction of QoL information from patient-generated content may offer a faster, lower-cost and low-burden complement to traditional QoL questionnaires, given that limitations such as symptom ambiguity are addressed in future work.

Background: Lung-protective ventilation (LPV) reduces complications of mechanical ventilation, yet adherence in intensive care (ICUs) remains inconsistent. Digital dashboards may support LPV by improving situational awareness and supporting protocol adherence. However, adoption of such tools in high-acuity clinical environments depends on a range of cognitive, professional and contextual determinants. The Measurement Instrument for Determinants of Innovations (MIDI) provides a validated framework to systematically assess these factors. Objective: To identify determinants influencing adoption of a newly piloted mechanical ventilation dashboard in the ICU using the MIDI framework. Methods: We conducted a single-center, cross-sectional evaluation among ICU healthcare professionals during a dedicated survey period within a pilot introduction of a mechanical ventilation dashboard at Amsterdam UMC. Participants completed a structured questionnaire consisting of 24 MIDI items adapted to the ICU context rated on a 5-point Likert scale (completely disagree to completely agree), supplemented by open-ended questions on perceived barriers and facilitators to its use. Determinants were classified as facilitators when ≥80% of respondents selected “agree” or “completely agree” and as barriers when ≥20% selected “disagree” or “completely disagree”. Open-ended responses were analyzed using a general inductive thematic approach. Results: A total of seventy-one completed questionnaires were analyzed, including responses from nurses, physicians, intensivists, ventilation specialists, and researchers in mechanical ventilation. Six determinants met criteria for facilitators: outcome expectations; self-efficacy; procedural clarity; low complexity; correctness; and observability. Two determinants met criteria for barriers: relevance for client; and professional obligation. Analysis of open-ended responses highlighted perceived barriers such as additional workload, the need for an extra device, overlap with existing systems, and limited role-specific relevance. Facilitators included improved situational overview, educational value, easier trend monitoring, and increased efficiency. Conclusions: This evaluation identified key determinants influencing adoption of a mechanical ventilation dashboard in ICU. While the dashboard was generally perceived as useful and easy to understand, adoption was shaped by determinants related to workflow integration, role-specific relevance, and professional responsibility. These findings suggest that successful introduction of digital clinical support tools in intensive care requires attention not only to technical design, but also to how such tools align with users’ roles, daily work processes, and shared clinical responsibilities. Systematic assessment of determinants provides actionable insight into adoption of digital decision-support tools in high-acuity care settings. Clinical Trial: Not applicable; this study was not a registered clinical trial.

Background: Occupational stress is a pressing health issue for academic staff, particularly in health sciences faculties where the demands of teaching, research, clinical supervision, and administrative responsibilities are significant. Extended periods of job-related stress can result in detrimental psychological and physical effects. Despite this, non-pharmacological stress management techniques, such as hydrotherapy, are not commonly employed or extensively studied within South African higher education institutions. Objective: The purpose of this study is to evaluate the level of knowledge and awareness that academic professionals have regarding hydrotherapy as a technique for managing work-related stress. Furthermore, it seeks to explore the changes in specific physiological stress-related variables among the Health Sciences faculty at Durban University of Technology. Methods: The study will adopt a quantitative longitudinal study design with a pre/post evaluation structure. Health Sciences academic professionals who satisfy the study's inclusion criteria will be recruited through purposive sampling. Data will be gathered using structured questionnaires and physiological assessments conducted both before and after the hydrotherapy intervention. Results: The Durban University of Technology Institutional Research Ethics Committee has granted ethical approval for the study protocol. The Faculty of Health Sciences has also provided institutional permission. With institutional approval secured, the recruitment of participants and the preliminary testing of data collection tools are set to begin in March 2026. Data will be analysed using SPSS version 29, employing both descriptive statistics and inferential analyses to evaluate changes in physiological variables before and after the intervention. The findings will be displayed in tables and graphs. Conclusions: This protocol describes a study examining the use of hydrotherapy as an additional method for addressing work-related stress among academic professionals in the Health Sciences. The results are anticipated to enhance evidence-based strategies for occupational wellness and guide the incorporation of non-drug stress management techniques in higher education settings.

Background: FDA-cleared artificial intelligence (AI) triage tools for intracranial hemorrhage (ICH) are increasingly deployed in clinical radiology. In real-world practice, perceived utility may depend not only on diagnostic performance but also on workflow friction, false-alarm burden, and calibrated trust when AI outputs conflict with radiologist interpretation. Objective: To characterize radiologists’ perceptions, trust calibration, and self-reported vigilance behaviors when using an FDA-cleared ICH AI triage tool in a national teleradiology network and to evaluate differences by neuroradiology subspecialty training. Methods: We conducted an anonymous cross-sectional survey of radiologists in a national teleradiology practice who had access to an FDA-cleared ICH detection AI overlay during routine noncontrast head CT interpretation. Survey domains included perceived reliability and usefulness, false-alarm burden, workflow integration, medicolegal concerns, and items designed to probe self-reported vigilance behaviors consistent with automation complacency. Responses used a 5-point Likert scale (Strongly agree, Agree, Neutral, Disagree, Strongly disagree). Results are summarized as agreement proportions (“agree”/“strongly agree”). We evaluated subgroup differences between neuroradiologists and non-neuroradiologists using Fisher exact tests. To reduce risk of spurious findings from multiple comparisons, we prespecified a primary endpoint and treated other items as exploratory with false discovery rate (FDR) control using the Benjamini–Hochberg procedure. Optional free-text responses were analyzed qualitatively to identify recurring themes. Results: Sixty-five radiologists responded (23 neuroradiologists; 42 non-neuroradiologists). Only 18.5% (12/65) agreed that false-positive alerts were infrequent enough to be acceptable. Trust was highly conditional: 50.8% (33/65) trusted the AI when it agreed with their interpretation, whereas only 3.1% (2/65) trusted it when it conflicted. The primary endpoint—agreement that false-positive workload outweighed benefits—was endorsed by 33.9% (22/65) overall and was more common among neuroradiologists than non-neuroradiologists (52.2% vs 23.8%; unadjusted P=.029). However, after FDR correction across exploratory items, no subgroup differences remained statistically significant. Self-reported vigilance reduction on AI-negative outputs was uncommon (6.2% overall; 0% neuroradiologists; 9.5% non-neuroradiologists). Free-text feedback emphasized artifact-driven false positives, delayed or inconsistent AI availability, consult burden, and medicolegal concerns. Conclusions: In a national teleradiology environment, radiologists reported substantial false-alarm burden and highly conditional trust when using an FDA-cleared ICH AI triage tool. Self-reported vigilance reduction was uncommon but present in a minority of users. Human factors–oriented optimization—including specificity improvements, earlier availability, better localization, and workflow-aware triage routing—may improve acceptance and perceived utility.

Background: The small intestine is central to nutrient digestion and absorption, while its epithelial barrier and resident gut microbiota maintain intestinal integrity and prevent passage of antigens, toxins and partially digested nutrients into the circulation. Evidence shows that lifestyle factors (such as sedentary behaviour, ageing, obesity) and diets high in refined carbohydrates and saturated fats disrupt the gut microbiota, impair intestinal barrier function and promote the phenomenon frequently termed “leaky gut”. In turn, enhanced intestinal permeability may allow lipopolysaccharide (LPS) and other luminal antigens to enter the bloodstream, trigger chronic immune activation and low-grade inflammation, raise insulin secretion and ultimately contribute to insulin resistance and elevated blood glucose. This process may precede the onset of prediabetes the intermediate metabolic state before full-blown Type 2 Diabetes Mellitus (T2DM) and thus represents a potentially critical window for prevention. Objective: This systematic review protocol will synthesise the published evidence on the relationship between gut barrier dysfunction, microbiota dysbiosis and progression from normal glucose tolerance through prediabetes to T2DM. Methods: This protocol was developed following the PRISMA-P 2020 reporting guidelines. Literature searches will be conducted across Google Scholar, PubMed, Scopus, and Science direct. Eligible studies will include published prospective observational, case-control, and cross-sectional research involving non-diabetic, prediabetic, and type 2 diabetic populations. The inclusion criteria will encompass all prediabetic participants aged 18 years and older, those who were not previously diagnosed with any small bowel disorders. Patients diagnosed with gestational diabetes, type 1 diabetes and condition that cause disturbances on the intestinal barrier will be excluded in the study. Eligible studies compared groups such as T2DM versus normoglycemic individuals, prediabetes versus normoglycemic individuals, or T2DM versus prediabetes. Only studies that reported the association between leaky gut (biomarkers of the leaky gut such as IFABP and zonulin) and the onset of prediabetes or T2DM will be considered.
The extracted data will be independently reviewed by a second reviewer, and any discrepancies will be addressed and resolved with input from a third reviewer. The risk of bias will be assessed using the Downs and Black checklist. Meta-analysis will be conducted using Review Manager version 5.4 to generate Forest plots, SPSS will generate funnel plots and the overall quality of evidence will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. Results: This systematic review will utilize publicly available data collected following the publication of this protocol. The protocol aims to guide the identification and analysis of studies investigating the relationship between leaky gut and the onset of prediabetes. Conclusions: The findings derived from this review will also help inform future research to be conducted in Durban, South Africa.

Background: Depression is the most common mental health disorder worldwide and frequently leads to workplace absences. As face-to-face treatment can be difficult to access app-based interventions are a popular solution, although their effectiveness in working populations and mechanisms of action are unclear. Deficits in executive functioning (EF) may contribute to the onset and maintenance of depression, and EF training is proposed to improve symptoms by enhancing EF. Responders to cognitive behavioural therapy (CBT) show improvements in EF, suggesting this may be one mechanism of action. Objective: This study investigated the effectiveness of app-based interventions (EF- or CBT-based) in reducing depressive and anxious symptoms, and improving workplace wellbeing, and whether changes in EF mediated improvements. Methods: 228 participants (147 female) with mild to moderate depression and anxiety were randomly assigned to either a waitlist control group, or to use an EF training app or a self-paced CBT app. Participants completed measures of depressive symptoms, anxious symptoms and workplace wellbeing at baseline, after the 4-week intervention period, and at 12-week follow-up. Results: EF training reduced anxiety and depressive symptoms at follow-up, but not at post-intervention, and did not affect workplace wellbeing. There were no reductions in depressive or anxiety symptoms in the self-guided CBT group, though workplace wellbeing was improved post-intervention and at follow-up. Improvements in EF did not mediate intervention-related changes in symptoms or workplace wellbeing. Conclusions: These results suggest app-based EF training may be effective at managing symptoms of anxiety and depression in a working population, whilst using self-guided CBT apps may improve workplace wellbeing. However, EF did not appear to be a mechanism of action of either intervention. Clinical Trial: The study was pre-registered on the Open Science Framework: https://osf.io/zsncj

Background: Affirming Care for lesbian, gay, bisexual, transgender, and queer (LGBTQ+) populations refers to culturally and clinically competent healthcare that recognizes specific health needs and provides respectful, inclusive, equitable, and non-discriminatory services that are supportive of diverse identities. LGBTQ+ populations face greater discrimination in healthcare, leading to higher levels of unmet health needs than the general population. Very few primary care practices in the United States have training for staff and clinicians on LGBTQ+ healthcare needs. Despite the growing needs for LGBTQ+ affirming care, there are no national standards or requirements for LGBTQ+ cultural competence training for primary-care healthcare providers in the United States. Objective: This study explores the accessibility and quality of online ‘grey literature’ providing LGBTQ+ affirming and culturally competent care information for primary care providers in the United States. Grey literature is produced by government, academic, business, and industry sources in formats not controlled by commercial publishing. Methods: We conducted a Google search of grey literature to identify readily available resources and training materials. Two thousand websites were screened. Those published in a language other than English before January 1, 2014, as well as those that were peer-reviewed literature or behind a paywall, were excluded. Fifty-four websites met the inclusion criteria for a full-text review. Results: We identified six themes from the existing academic literature: (1) affirming physical and visual environments, (2) sexual orientation and gender identity (SOGI) data collections, (3) training on LGBTQ+ health needs, (4) anti-discrimination policies, (5) appropriate, relevant services for LGBTQ+ patients, and (6) use of inclusive language. We then applied these themes as a deductive coding framework to the web-based sources and, during analysis, two additional sub-themes emerged: (1) staff diversity, (2) health inequalities and inequities.
Findings revealed that not every web-based source addressed all themes. This unequal distribution of coverage across these themes means that providers must consult multiple web-based sources to obtain a comprehensive understanding. Additionally, existing grey literature resources often lacked depth, technical detail, and practical guidance, making it difficult for primary care providers to access actionable information on LGBTQ+ affirming care. ‘Training on LGBTQ+ health needs’ was the most frequently covered theme, and ‘SOGI data collection’ was the least addressed. Study limitations included geolocation biases and embedded advertisements in the Google search results. Conclusions: The study highlights that grey literature is insufficient for self-guided training. We recommend integrating formal LGBTQ+ affirming care training into medical and nursing curricula, as well as professional associations and continuing education, particularly amid growing federal and state-level restrictions on LGBTQ+ healthcare.

Background: The consequences of medication errors are substantial as they pose a significant threat to the high-risk population, including paediatric, neonatal and geriatric patients. Computerised Provider Order Entry (CPOE) systems and clinical decision support systems (CDSS) are increasingly implemented to reduce medical errors by automating prescribing processes and providing real-time decision support. While alerts have been shown to provide value, barriers to widespread implementation exist in the form of alert fatigue and usability problems. Objective: This systematic review and meta-analysis assessed the effectiveness of CPOE and CDSS in reducing medication errors across diverse populations and clinical environments. Methods: A systematic review was conducted following the Preferred Items for Systematic Review and meta-analyses (PRISMA guidelines), with four databases searched up to February 2025 for studies evaluating the effects of CPOE and CDSS implementation on medication error in paediatric and geriatric populations. We included only cohort and prospective studies, not restricted by language or country of publication. Single measures of continuous outcomes on medication error rates were extracted from each study. The Comprehensive Meta-analysis (CMA) was then applied to perform separate analyses to compare the outcome pre-and post-CPOE/CDSS implementation. A random-effect meta-analysis was conducted, with subgroup analyses to assess differences by population, healthcare setting, and system design. The Newcastle–Ottawa Scale was used for quality appraisal. Forest plots and funnel plots were applied for pooled results and publication bias assessment. Results: Fourteen studies met the inclusion criteria (paediatric: n = 12; geriatric: n = 2), all rated as good quality. In paediatrics, 10 of 12 studies reported significant reductions in medication errors post-implementation. Pooled analysis showed error rates were almost threefold higher pre-implementation (OR = 2.97; 95% CI 2.81–3.14), with substantial heterogeneity (I² = 94%) but consistent positive direction of effect. In geriatrics, both studies demonstrated significant reductions with no heterogeneity (I² = 0%) (OR = 2.45; 95% CI 2.29–2.62), though evidence remains limited in scope and setting due to the small number of studies. Descriptive synthesis indicated that CPOE/CDSS can intercept high severity errors, such as overdoses of high-risk medications, before reaching patients, although most studies assessed potential rather than actual harm. Meta‑regression showed study location as a significant moderator, with greater effects in North American studies compared to those conducted in Asia. No publication bias was detected, but regional variation suggests contextual factors such as healthcare infrastructure, informatics maturity and influence system effectiveness. Conclusions: CPOE/CDSS significantly reduces medication errors in special populations, with strong and consistent benefits in paediatrics and promising but limited evidence in geriatrics. Despite heterogeneity in paediatric studies, the direction of effect was uniformly positive. The systems also show potential to reduce the severity of harmful errors, although robust evidence on actual patient harm is lacking. Optimising and tailoring CPOE/CDSS to specific patient populations and healthcare settings, while addressing alert fatigue and workflow integration, are essential to maximise impact. Further research should expand the geriatric and neonatal evidence base, assess long-term outcomes and explore advanced decision support capabilities to enhance patient safety and clinical impact.

Background: Ecological momentary assessment (EMA) enables real-time, repeated evaluation of participants' emotions, thoughts, and behavioral patterns in natural settings. It effectively mitigates the retrospective bias inherent in traditional surveys and facilitates a longitudinal understanding of health status. However, its feasibility, practicality, and methodological details for monitoring and promoting maternal health remain unclear. Objective: To conduct a scoping review of studies on the application of EMA in maternal health management, providing a reference for future research and further promotion of maternal and infant health. Methods: Using the Joanna Briggs Institute (JBI) scoping review guidelines as the methodological framework, we searched the Web of Science, PubMed, CINAHL, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database, Wanfang Database, and VIP Database. The search covered publications from the inception of each database to December 2025, and the included studies were subjected to a comprehensive analysis. Results: The search yielded 2,989 publications, of which 14 were ultimately included. The findings were summarized across three dimensions: study design characteristics (publication year, country, and study design features, such as sample size, study population, and outcome measure type); EMA data collection methods (EMA schedule characteristics, such as monitoring cycle, duration, and data sampling methods, such as fixed-time, random-time, or event-based sampling); and EMA response-related outcomes (participation rate and response rate). Conclusions: The EMA effectively mitigates the recall bias inherent in traditional assessment methods, offering novel approaches to enhance the quality of maternal health management. This enables longitudinal monitoring of maternal experiences in natural settings, facilitating the early identification of abnormal physiological, psychological, and behavioral issues during pregnancy and postpartum. This allows timely intervention to safeguard maternal and infant health. Future research should refine EMA study designs and implementation formats to fully leverage their potential in promoting maternal health and personalized interventions for maternal-infant wellness.

Background: Unstructured clinical text remains a major barrier to interoperable data reuse and large-scale secondary analysis in healthcare. Large language models (LLMs) have the potential to automate the extraction of structured clinical information; however, their application is limited by the scarcity of high-quality annotated training data. Objective: To address these limitations, this study aims to develop and validate a scalable, privacy-preserving framework that utilizes synthetic data generated from structured Fast Healthcare Interoperability Resources (FHIR) to fine-tune open-source LLMs for the effective extraction of interoperable clinical information from unstructured text. Methods: We evaluated an LLM–based pipeline for extracting structured clinical information from cancer-related discharge letters and mapping it to representations compatible with Fast Healthcare Interoperability Resources (FHIR). To enable large-scale supervised training, we developed a random sample generator that creates synthetic discharge letters using Qwen3 235B by randomly sampling and aggregating structured FHIR data from 41,175 cancer patients. The resulting synthetic discharge letters (n=75k) were paired with their originating structured data, forming a large-scale dataset for fine-tuning MedGemma 27B. Evaluation was conducted on the synthetic test dataset (n=7,500), real-world discharge letters (n=30) which are evaluated by physicians and a medical student, and a comparative one-shot approach using open-source models (Qwen3, LLaMA, and GPT-OSS). Results: The fine-tuned model achieved high extraction performance across multiple clinical entities, including full ICD diagnosis codes (F1 = 0.84), tumor-related information (0.99), laboratory values (0.99), medication names and dosages (0.99), and ATC medication codes (0.94). Extraction of procedure-related information was more challenging but remained reliable, with F1 scores of 0.63 for OPS codes and 0.90 for procedure descriptions. In a one-shot comparison of general-purpose LLMs with the fine-tuned model, the fine-tuned model consistently outperformed general-purpose LLMs in nearly all extraction categories. When applied to real-world discharge letters, performance remained robust, with F1 scores of 78.9% for ICD diagnoses, 86.1% for tumor-related information, 93% for medications, and 61.3% for procedures. Conclusions: These results demonstrate that synthetic text generation from structured clinical data enables effective and scalable training of LLMs for extracting interoperable, multi-entity clinical information from unstructured documentation.

Background: In recent years, the field of digital health has grown exponentially, leading to notable benefits such as easier access to health-related information, but also to content saturation and misinformation. Thus, it is crucial to identify digital health tools that provide meaningful value and assess their real-world impact. Objective: This pre-registered study’s goal was to quantitively assess the LONDI platform, a German platform designed for different user groups supporting children with learning disorders. This assessment focused on user groups of mental health professionals (i.e., learning therapists and school psychologists), and was grounded on four of the five RE-AIM-framework dimensions: Reach, adoption, implementation, and maintenance. Methods: Data was collected over a 10-month period, between May first 2024 and March first 2025. The reach dimension was measured via a pop-up questionnaire (N=1324), collecting demographic and professional experience data. The adoption dimension was measured via a second pop-up questionnaire (N=160), measuring user experience (UX) and reuse intention for the platform’s help system. The implementation dimension was measured via web analytics (N= 37,133), measuring reading time for pages intended for mental health professionals. Moreover, this dimension was also assessed by comparing chatbot engagement rates with industry benchmarks. The maintenance dimension was measured via web analytics as well, comparing the usage in the previous (N= 20,496), and the current platform version (N= 37,133) in terms of number and location of users, time spent on the platform, number of actions per visit, and used devices and software. Results: 22% and 10.64% of the users that filled out the first pop-up questionnaire stated that they were learning therapists or school psychologists, respectively, exceeding their percentage in the German population (< 0.01%). The second pop-up questionnaire revealed an overall mean UX score of 1.46, surpassing the benchmark average, and UX ratings predicted intention to reuse. Time spent on the pages intended for mental health professionals was below the time needed to read them. The 0.18% rate of chatbot engagement was very low compared with industry benchmarks of 35-40%. Usage changed in the two compared time periods, and most strikingly, there was an 81.2% increase in the number of users. Conclusions: The study provides evidence to the LONDI platform’s optimal public health impact in terms of the reach, adoption, and maintenance RE-AIM-framework dimensions. Further research and endeavors and are needed to better understand and improve the platform’s impact in terms of the implementation dimension.

Background: In Canada, Black students continue to be underrepresented in medical schools and face institutional barriers, including limited access to the information necessary for their admission and their academic path. The Black Medical Students Association of Canada (BMSAC) has developed a bilingual website for these students. Objective: The purpose of this research is to evaluate the quality, accessibility and usefulness of the site and make recommendations for its improvement. Methods: A cross-sectional survey was conducted through an online system using the System Usability Scale (SUS), a validated website user experience evaluation tool. Three open-ended questions were added to the survey to identify areas for improvement. The data from the SUS were analyzed using descriptive statistics and the answers to the questions underwent thematic analysis. Results: 50 participants responded to the survey (24 in English and 26 in French). The overall SUS score was 75.8. The SUS scores for the English and French versions were 77.0 and 74.7, respectively. More than three quarters of respondents lived in Quebec. Respondents learned more about the available resources and recommended including more images illustrating organized events on the site. Conclusions: The overall SUS score and that of English and French respondents were considered satisfactory. The lack of visual support, updated information and some technical problems seemingly explain these results. Strong Quebec representation also indicates the need to promote the site elsewhere in Canada.

Background: Digital interventions for childhood obesity prevention have potential to support healthy lifestyle behaviors, but real-world effectiveness is often limited by low engagement and poor alignment with children’s developmental needs and family contexts. Co-creation with end users and clinical stakeholders can generate actionable requirements to inform the design of age-tailored, acceptable, and scalable mobile health (mHealth) solutions. Objective: This study aimed to (1) elicit user requirements for a pediatric mHealth app to support healthy lifestyle behaviors relevant to overweight/obesity prevention and (2) examine how requirements differ across child age groups and stakeholder types (children/adolescents, parents, and health professionals). Methods: A total of 113 children and adolescents, 47 parents and 13 health experts participated in co-creation workshops as part of the BIO-STREAMS project. Children in each age group participated in two 90-minute workshops that were conducted between November 2024 and March 2025 across five European countries. Participants responded to questions regarding healthy lifestyle behaviors and were subsequently invited to articulate their vision for a potential health application. Two researchers analyzed the data using a thematic analysis approach. Results: Stakeholders described mHealth requirements that clustered into distinct but complementary domains. Children emphasized (1) practical health guidance (e.g., food and activity ideas), (2) personalization and goal support, (3) engaging and interactive features (e.g., gamification and feedback), and (4) accessible learning resources. There was clear age differences: younger children preferred concrete, routine-based guidance, while older adolescents more often referenced balanced lifestyle concepts, mindful decision-making, and mental well-being–related support. Parents prioritized (1) guidance and coaching features, (2) tracking that is flexible and not overly burdensome, (3) usability and comfort considerations (including oversight preferences), and (4) credible information sources and functionality expectations for family use. Health professionals highlighted (1) clinically meaningful monitoring and communication, (2) stigma-sensitive and developmentally appropriate feedback, and (3) considerations for managing and governing digital health platforms used in pediatric obesity prevention. Conclusions: The presented co-creation with children, parents, and clinicians produced actionable requirements for designing an age-tailored pediatric mHealth intervention for obesity prevention and to support relevant healthy lifestyle behaviors. Findings support a multi-actor approach (child-, parent-, and health expert-relevant views), strong personalization, and engagement-focused interaction design, while addressing usability, burden, and appropriate oversight to facilitate adoption in real-world family and clinical contexts. Clinical Trial: The study was registered at ISRCTN (ISRCTN44876661, registered on 23/04/2025)

Background: Although motorcycle-based food delivery workers face significant risks of accidents, the focus on general traffic accidents has left the multidimensional nature of safety understudied. Objective: This study addressed this gap by investigating how occupational fatigue and health behaviors predict the Traffic Accident Risk Index and its subdomains (near-miss experiences, self-rated accident anxiety, and other-rated accident anxiety). Methods: Data were collected from 336 South Korean delivery workers via an online survey and analyzed using multiple linear regression. Results: Occupational fatigue was positively associated with the overall risk index and all subdomains. Non-use of helmet and insufficient physical activity were associated with higher Traffic Accident Risk Index and self-rated accident anxiety. Current smoking was associated with near-miss experiences. Conversely, shorter break times were associated with lower accident risk and near-misses than breaks exceeding 2 h. Conclusions: Occupational fatigue was associated with higher overall accident risk, more near-misses, and greater accident-related anxiety. Modifiable health behaviors showed additional domain-specific associations. Prevention efforts may benefit from combining fatigue management with strategies to improve helmet use, increase physical activity, and support smoking cessation. Future research should refine the measurement of break time and establish evidence-based rest guidance for motorcycle-based delivery workers.

Background: Type 2 diabetes (T2D) and high blood pressure (HBP) are major public health challenges worldwide, leading to serious complications, disability, and mortality. In Tunisia, the contribution of civil society organizations (CSOs) to the prevention and management of these non-communicable diseases (NCDs) remains limited. Objective: This study aimed to assess the epidemiological situation of T2D and HBP in North-East Tunisia and to examine the added value of CSO involvement in research and advocacy. Methods: A community-based participatory research approach was implemented, coordinated by the Science Shop at the Institut Pasteur de Tunis, in partnership with the Regional Association of Diabetics in Zaghouan. Epidemiological data were collected from 420 volunteer participants to estimate the prevalence of T2D and HBP in northeastern Tunisia (Zaghouan region) and to identify associated risk factors. In parallel, members of civil society organizations (CSOs) actively contributed to identifying community priorities, awareness gaps, and barriers to effective disease management Results: Findings revealed a concerning increase in the prevalence of T2D and HBP in the region, emphasizing the urgent need for targeted interventions. The engagement of CSOs strengthened the relevance and impact of research, improved community participation, and facilitated dialogue with policymakers. Conclusions: In conclusion, this study underscores the pivotal role of CSO–research partnerships in bridging science and society, promoting evidence-based health actions, and enhancing policy responses to NCDs in Tunisia

Background: Rapid digital transformation is reshaping health care worldwide. To ensure that digital technologies improve care quality and support national priorities, health systems need systematic digital health strategic planning rather than technology‑first or vendor‑driven decisions. Saudi Arabia’s Vision 2030 calls for the localization of health innovation and digital capability. King Saud University Medical City (KSUMC) is a large academic medical centre seeking to institutionalize innovation and digital health capabilities. Objective: This study aimed to develop a strategic framework for a digital health innovation hub at KSUMC. The framework aligns with Vision 2030’s localization goals and draws on global digital health strategic planning guidance to support innovation, knowledge transfer and intellectual‑property (IP) commercialization. Methods: A qualitative case study was undertaken from April to June 2025 using semi‑structured interviews with 14 purposively sampled stakeholders from clinical, administrative and innovation roles at KSUMC. Data were coded thematically using an interpretivist approach informed by diffusion of innovation theory, the Context‑Actor‑Mechanism‑Outcome (CAMO) lens and systems thinking. Thematic findings were interpreted in light of global digital health strategic planning frameworks, including the World Health Organization (WHO) Global Digital Health Strategy and the Centers for Disease Control and Prevention (CDC) Global Digital Health Strategy. Results: Five interrelated themes influenced digital health innovation: (1) Leadership and culture, senior leadership supported innovation but bureaucratic culture slowed experimentation; (2) Resources and operations, high clinical workload, fragmented information systems and insufficient funding constrained digital health initiatives; (3) Knowledge exchange, informal networks existed, yet there were few structured mechanisms for knowledge transfer and IP management; (4) Incentives and capacity, staff were motivated by recognition and professional development but lacked protected time and incentives to engage in digital innovation; (5) External policy environment, Vision 2030 provided momentum for digital health, but reliance on external consultants risked undermining internal capability. These themes informed a Strategic Planning Framework that emphasizes leadership‑driven culture change, cross‑sector partnerships, systematic knowledge‑transfer mechanisms, ethical IP policy, and sustainable funding. Conclusions: Digital health transformation requires more than the acquisition of technology; it demands systematic strategic planning, continuous stakeholder engagement and alignment with national policy. The proposed framework for KSUMC prioritizes leadership, governance, capacity building, knowledge transfer and IP management. By integrating WHO guidance on national digital health strategies, such as multistakeholder leadership, adaptable infrastructure, and robust governance, with agile planning methods, the framework supports both periodic and continuous strategic planning. This case highlights the need for academic medical centres in emerging economies to adopt evidence‑based strategic planning to harness digital health opportunities and achieve sustainability.

Background: mWorks is a co-designed web-based self-management intervention developed to empower persons with common mental disorders on sick leave during their return-to-work process. However, a lack of knowledge regarding how the delivery and receipt of mWorks occur in practice impedes further progress. It is suggested that evaluations, according to the Medical Research Council framework, provide a format for studying to examine the contextual factors influencing implementation, how mWorks was delivered in practice, and how service users and professionals experienced and responded to the intervention. Objective: To evaluate the process of implementing the mWorks, specifically focusing on assessing the intervention's delivery in relation to the context, implementation process, and impact mechanism. Methods: This case study is limited to a single case study design. The case was bounded by the delivery period of 10-weeks in a primary and specialist mental health service context. During this period, return-to-work professionals (n=2) and service users (n=6) collaborated to initiate mWorks usage. Both qualitative and quantitative methods were used to triangulate multiple data sources. Results: The pandemic and mental health problems posed contextual barriers, particular during recruitment. However, the legitimacy of mWorks facilitated overall implementation. The delivery was performed according to plan with minimal adaptions. All users adhered to the intervention, and dialogue meetings were highly valued. mWorks was used flexibly according to users’ needs, both during sick leave and at work. The potential impacts included a transformative process for users, fostering acceptance, self-esteem, self-compassion, and a sense of control. It also had the potential to prevent mental ill-health, transform negatives into positives, facilitate disclosure of mental health, and support goal setting. The use of quantitative measures for empowerment, engagement, self-efficacy, depression stigma, and quality of life proved feasible and supported the assumptions and direction of results. Conclusions: The recruitment stage of the implementation program encountered significant contextual barriers. However, once the delivery stage began, the implement of mWorks proved to be feasible. Despite the limited scope of this study with a small number of participants, the triangulation of data suggests that both users and professionals benefited from mWorks.

Background: Degenerative meniscus findings are common in middle and older adults, and current guidelines favor nonoperative care. As patients increasingly turn to portal systems to view imaging results and communicate with their physician, patient-facing wording may shape downstream treatment preferences and expectations. Objective: To determine whether subtle differences in physician message framing about an identical degenerative meniscus tear influences: preferred management; expectations for improvement with conservative therapy; and satisfaction when a physician recommends a different plan. Methods: A prospective, randomized, cross-section 37-question survey was distributed to U.S. lay adults recruited via Amazon Mechanical Turk. Respondents were presented with a controlled vignette, putting them in the position of a 60-year-old patient with knee pain due to a degenerative meniscus tear. Participants were randomized 1:1:1 fashion into three physician portal-message framing groups: Neutral, Degenerative, Damage. Outcomes were preferred next step in treatment, expected improvement with physical therapy, and retained satisfaction in a follow-up scenario in which the treating physician disagreed with a respondent’s treatment preference. Results: Of the 266 completed responses, 195 were included for analysis (Neutral n=67; Degenerative n=63; Damage =65). Treatment preferences differed significantly across groups (χ²(2) = 6.105, p = 0.047). The Damage group was more likely to prefer aggressive interventions (n/N=48/65, 58.7%) compared to the Neutral (n/N=36/56, 53.7%) and Degenerative groups (n/N=37/63, 58.7%). Damage framing significantly increased the odds of a respondent preferring invasive options (OR 2.20, 95% CI 1.15-4.23; p=0.012). Expectations for physical therapy success differed significantly (χ²(4)=12.27, p=0.015), with the Damage group being most pessimistic about conservative care versus the Neutral and Degenerative groups. Retained satisfaction under physician disagreement did not differ by framing group (χ²(6)=6.68, p=0.351), but did differ significantly by initial treatment preference (p=0.028), and was lowest among respondents preferring steroid injection. Conclusions: Patient-portal message framing about an identical meniscal MRI finding significantly shifted management preferences and confidence in conservative therapy. Avoiding pathologizing language may help support guideline-concordant care and reduce pessimism toward beneficial conservative therapy.

Background: Telehealth and artificial intelligence are increasingly used in specialized palliative outpatient care, offering potential benefits but facing challenges, particularly regarding user acceptance. To date, there is a lack of knowledge about the extent to which digital health applications may be transferable between different areas of palliative care. Objective: This study evaluates the transferability of concrete needs, expectations, and concerns regarding telehealth and artificial intelligence from specialized outpatient palliative care for children to specialized outpatient palliative care for adults, using the example of the PalliDoc Mobile App. Methods: Two specialized outpatient palliative care teams for adults using PalliDoc (a pediatric-origin mobile app) were surveyed employing a sequential mixed-methods approach to conduct the needs assessment: a focus group study with quantitative needs prioritization, followed by a questionnaire survey on user acceptance. 25 members from both teams, representing urban and rural care areas in Germany, participated in the focus groups. 17 responded to the questionnaire. Results: A total of 13 needs were identified within the examined care teams for adults, with functions focusing on voice input and output as well as organizational tasks being the highest priority. Unlike in pediatrics, video contacts, telemetry and electronic patient-reported outcome measures are neither used here now nor intended to be used in the future. The identified concerns predominantly addressed the potential risk of artificial intelligence–assisted documentation altering or distorting healthcare professionals’ perception of patient-related information. Conclusions: Cross-setting telehealth applications may work but are no “plug-and-play solution”. Needs and concerns in each setting should be addressed to guarantee customized services. Clinical Trial: This study is registered in the German Register of Clinical Trials under the ID DRKS00036054 (https://www.drks.de/search/de/trial/DRKS00036054/details).

Background: Psychotic disorder represents a leading cause of disability worldwide, and relapse in psychosis is common. Artificial intelligence (AI) is increasingly recognized as a method which could aid clinical monitoring in psychosis. Objective: This scoping review aims to identify studies which have used methods with an AI component to detect relapse in psychosis. Methods: A systematic search strategy was conducted on PubMed, PsycINFO and Embase from inception to January 2026. Observational studies, randomized controlled trials and quasi-experimental studies which used AI methods to detect relapse in psychosis were eligible for inclusion. Screening and data extraction procedures were conducted by at least two reviewers working independently. Findings were extracted, charted and described using narrative synthesis based on data extraction and consensus meetings with the research team. The scoping review was prospectively registered with Open Science Framework. Results: Relevant studies identified (n = 10) included use of digital tools such as smartphone and smartwatch-based monitoring, ecological momentary assessment tools, social media activity and internet searches. Digital phenotyping via smartphones and wearables emerged as the most common method for data collection. Efficacy of AI models varied with sensitivity (or recall) ranging from 0.25 to 0.77 and specificity ranging from 0.06 to 0.88. Reported area under the receiver operating characteristic curve for models ranged from 0.63 to 0.78. AI models were heterogenous across studies, and most study findings were not replicated. Conclusions: This scoping review highlights both the promise and current limitations of AI in psychosis relapse prediction. Digital phenotyping research in detection of psychosis relapse has progressed, but future studies need to include larger numbers of participants and should incorporate other methods such as use of large language models. Future studies will require large collaborations aiming to deliver AI tools for use in real world clinical practice. Clinical Trial: N/A

Research has highlighted clinicians’ lack of confidence in safely diagnosing and managing dermatological disease in patients with skin of colour (SOC).The imagery and language surrounding skin colour in medical education often presents a narrow spectrum of individual experiences and the undergraduate voice appears to be lacking from these discussions. We aimed to capture the descriptors which medical students use in relation to their own skin and how this relates to their education, to better understand how we can diversify the language used, for the benefit of the patient and future clinician.
An ethically-approved, digital survey was distributed to all UK medical schools between October 1st and December 31st 2024. Participants were asked to describe their skin type at baseline, when inflamed, and in relation to the Fitzpatrick scale; rate preparedness to examine and discuss differences in skin conditions in SOC; suggest how best to describe SOC when ethnicity is unknown; and describe any experiences of unacceptable SOC terminology used in the context of medical education.
The survey generated 367 responses from 21 different medical schools. Self-ascribed ethnicity included: White British/Irish/White other (48%), Black/African/Caribbean/Black British (10%), Asian/Asian British (30%) and Mixed White/Black/Asian (7%) and Other (5%). The responses demonstrated that neither the pictorial nor text versions of the Fitzpatrick scale adequately represent how medical students consider their own skin, with 56% positioning themselves outside of the six images. The top descriptors of skin colour reflected that most participants self-identified as: brown (125 mentions), pale (123) and white (116). For inflamed skin, the terms red or reddish (337) were most frequently used, followed by pink (97) and brown (27). There were differing views on the use of ethnicity-related terminology where patient ethnicity is unknown. A total of 71% and 75% of participants felt between neutral and unprepared in relation to seeing patients with diverse skin tones and discussing differences in the presentation of dermatoses in SOC with patients, respectively.
Our findings suggest that skin descriptors and imagery in medical education needs to encompass greater variation in skin tone. We recommend further involvement of medical students in the diversification of undergraduate curricula, and for educators to consider the language they use to improve comprehension and preparation for clinical practice.

Background: Ask any educator, and they will respond that engagement is an important factor in their teaching. However, engagement is a complex, multidimensional construct comprising behavioural, cognitive, emotional, and agentic dimensions. Despite growing interest in this area, the conceptualisation and measurement of engagement in medical education remain inconsistent. Objective: This systematic review aims to examine how engagement is defined, conceptualised, and measured in studies involving medical students. Methods: A systematic literature search was conducted in February 2025 across five databases for peer-reviewed studies published within the last decade. Studies were included if they focused on medical students, collected original data, and measured engagement within the context of a medical curriculum. Data extraction and screening were performed independently by two reviewers following PRISMA guidelines. Studies were analysed for their conceptual framework, dimensions of engagement measured, data collection methods, and study design. Results: A total of 26 studies that met the eligibility criteria were included in this systematic review. Most studies measured behavioural (n=21), cognitive (n=19), and emotional engagement (n=17), while agentic engagement was least frequently measured (n=4). Most studies employed a quantitative approach, using survey instruments (n=14) and engagement metrics (n=5) to measure engagement, while a small number of studies adopted a qualitative approach, including interviews (n=4) and observations (n=4) to measure engagement. Engagement was mainly measured as a multidimensional construct, but some studies treated it as a unidimensional construct Conclusions: Engagement remains inconsistently and often poorly defined, as evidenced by the exclusion of more than half of initially screened studies for lacking rigorous measurement of engagement. The rise of technology-driven interventions has led to an increasing interest in ensuring that students are engaged in learning to achieve the desired learning outcomes successfully. Future research should systematically incorporate behavioural, cognitive, emotional, and agentic engagement dimensions to advance understanding and enhance educational practices.

Background: Hospital admission is associated with increased sedentary behavior and low levels of physical activity. Hospitals have developed several strategies and interventions to address this unwanted inactivity and increase patient movement during admission. Self-monitoring of physical activity is a promising approach to support activity during hospital stays. Objective: This study investigated whether providing patients real time-physical activity feedback, compared to receiving no real time physical activity feedback, supported patients in maintaining activity levels in the cardiology ward. Methods: A Hybrid Type 2 interrupted time series design was applied. In Phase 1 (24 weeks), patients wore accelerometers (PAM AM400) with data visible only to healthcare professionals. In Phase 2 (24 weeks), self-monitoring was introduced using a ward-based screen that provided patients real-time feedback on daily physical activity. Implementation outcomes were evaluated within the RE-AIM framework, with “Maintenance,” defined as daily physical activity trends over time, serving as the primary outcome. The other RE-AIM dimensions (Reach, Effectiveness, Adoption, and Implementation) were assessed as secondary outcomes. Results: A total of 159 patients were included (75 in Phase 1, 84 in Phase 2). Daily physical activity levels were expressed as active minutes per day. No significant immediate change in daily activity occurred at the start of Phase 2 versus the end of Phase 1 (β = –0.127, p = 0.811). In Phase 1, physical activity declined statistically significantly over time (β = –0.002, p < 0.001; ~6% decrease per month). In Phase 2, following introduction of the self-monitoring intervention, this decline was no longer observed, and activity levels were maintained. A significant phase interaction (β = 0.002, p = 0.027) confirmed stabilization of physical activity levels in Phase 2. Secondary RE-AIM outcomes did not differ between phases. Conclusions: The decline observed when only healthcare professionals accessed the data was no longer present once patients could monitor their own physical activity. Although seasonal influences cannot be excluded, these findings suggest that patient self-monitoring may support the maintenance of physical activity during hospital stays. Sustainability is complex, and determining the effect of patient self-monitoring alone remains challenging. Larger studies are needed to confirm these results. Clinical Trial: Trial registration was not required.

Background: The increasing adoption of Artificial Intelligence (AI) in healthcare, particularly within Clinical Decision Support Systems (CDSSs), is transforming clinical practice and decision-making. Although AI-CDSSs hold the potential to improve diagnostic accuracy, operational efficiency, and patient outcomes, their implementation also creates ethical, technical, and regulatory concerns, affecting healthcare professionals’ willingness to adopt these systems. Objective: Building on a value-based perspective, the study integrates the Unified Theory of Acceptance and Use of Technology (UTAUT) framework as determinants of perceived benefits and a risk-based perception model as determinants of perceived risks to develop a unified model exploring clinicians’ behavioural intention to adopt AI-enabled CDSSs. Methods: A self-administered cross-sectional survey was distributed to licensed healthcare professionals to examine how validated factors influence perceptions of risks and benefits. Responses were collected from 215 clinicians across Italy and the United Kingdom. Recruitment was undertaken using email invitations, attendance at academic conferences, and direct approaches within healthcare settings. Results: Perceived Benefits were found to be the strongest positive predictor of clinicians’ intentions to use AI-enabled CDSSs (β=.45, p<.001), whereas perceived risks had a significant negative effect (β=-.18, p=.002). Performance Expectancy and Facilitating Conditions significantly increased the adoption intentions, whereas Effort Expectancy and Social Influence were not significant. Among the risk antecedents, Perceived Performance Anxiety, Communication Barriers, and Liability Concerns were significant predictors of Perceived Risks. The model explained 46% of the variance in the intention to use AI-enabled CDSSs. Conclusions: The findings offer theoretical and practical insights into human factors influencing AI adoption in clinical practice, underscoring the importance of value alignment, professional accountability and institutional readiness, and highlighting the need to foster clinician trust in AI tools beyond the boundaries of technical performance.

Background: The COVID-19 pandemic significantly increased adoption of virtual care, including patient-to-provider secure messaging. However, this surge has heightened physician workload and burnout and has raised concerns about message appropriateness and liability among physicians. Objective: This study characterizes secure messaging use in Canadian hospital-based specialty care and explores the experiences of healthcare providers, administrative staff, and patients. Methods: We employed a convergent mixed-methods design, analyzing aggregated electronic health record (EHR) usage data and qualitative interview data. The study was conducted at Women’s College Hospital in Toronto, Canada, across four high-messaging specialty clinics: mental health, rheumatology, dermatology, and surgery. Quantitative data (Oct, 2019-Oct, 2022) detailing message volumes, response patterns, and timing. Semi-structured interviews explored messaging workflows, barriers, and facilitators. Data were analyzed separately, then converged to identify areas of convergence and divergence. Results: Message volumes surged post-pandemic, particularly in mental health. The monthly message rate per patient varied, with higher rates in mental health and rheumatology. Physicians reported negative experiences due to increased workload, lack of compensation, and inadequate integration into clinical workflows. High patient-to-physician ratios and limited nursing support for message triage were associated with a poor messaging experience. Patients and administrative staff valued messaging for its convenience, accessibility, and efficiency. A key finding was the poor engagement of all user groups in decisions regarding messaging implementation. Conclusions: The study highlights a disconnect between the high perceived value of secure messaging for patients and administrative staff and the negative experiences of physicians. Successful implementation requires thoughtful integration into care models, clear guidelines for patient use, and proper triage and "channel management" to guide patients to appropriate visit modalities. Future research should explore triaging algorithms as part of a digital front door, specialty-specific variations and the crucial role of nursing staff in message management.

Background: Emotional cognition deficits are a core feature of autism spectrum disorder (ASD) and contribute significantly to social difficulties in affected children. Digital, app-based training may offer scalable, structured practice, but evidence from randomized pilot trials remains limited. Objective: To evaluate the feasibility, acceptability, and preliminary efficacy of the Autism Emotion Cognition Training System (AECTS), a tablet-based, parent-mediated program designed to support emotional cognition in young children with ASD. Methods: We conducted a single-center, two-arm, parallel-group randomized controlled pilot trial between April and October 2025. Children aged 4–8 years with ASD were assigned to AECTS plus treatment as usual (TAU) or TAU alone for 8 weeks. Feasibility and acceptability were assessed in the intervention group using a study-specific mixed-methods questionnaire (25 Likert items and 5 open-ended questions). Preliminary efficacy was explored using the Social Responsiveness Scale (SRS) and the Clinical Global Impression (CGI), with ANCOVA adjusting for baseline SRS scores. Results: Of 20 randomized participants, 19 completed the trial (10 in the intervention group and 9 in the control group). Caregiver-rated feasibility was high across domains (mean scores 3.92–4.70 out of 5), with the highest ratings for overall acceptability and technical feasibility. Usability showed the lowest score and greatest variability. Qualitative analysis identified four themes: (1) strong but module-specific engagement, (2) smooth operation with unclear system status, (3) variable generalization to daily life, and (4) requests for smarter personalization and realistic scenarios. On secondary outcomes, SRS scores favored the intervention group but were not statistically significant. CGI outcomes were comparable between groups. Conclusions: This pilot trial demonstrated that AECTS is a feasible and acceptable digital intervention for children with autism, with positive caregiver feedback and preliminary signals of benefit. Although clinical efficacy was not statistically significant, favorable trends in social responsiveness suggest potential value. Future large-scale trials with enhanced usability, adaptive personalization, real-life social scenarios, and caregiver support are warranted to establish the intervention’s effectiveness and scalability.

Background: Comparative genomics is essential for understanding evolutionary relationships, yet visualizing and analyzing circular genomes like plasmids and genomes of mitochondria or chloroplasts remains challenging. Current software often relies on fragmented, single-algorithm approaches that struggle to efficiently capture the complex architecture of non-coding regions and structural rearrangements. Objective: To address these limitations, we developed the Circular Genome Comparison Tool (CGCT), a hybrid platform designed to integrate global and local alignment strategies. This tool aims to provide a robust, interactive visualization of circular genomes, resolving both large-scale synteny and fine-scale nucleotide divergence in coding and non-coding regions. Methods: CGCT is implemented as a stand-alone Python-based desktop application that requires no external runtimes or internet connection. It employs a novel hybrid pipeline combining an improved progressiveMauve for global synteny, SibeliaZ for local topological adjacency, and BLASTn for sequence sensitivity, all accessed through an interactive visual interface for dynamic analysis and high-resolution export. Results: Validation on mitochondrial, plasmid, and chloroplast datasets showed CGCT effectively "sutures" circular topologies, and reveals hidden "pseudogene-gene graveyards" and ORFs not properly recognized by BLAST+. The hybrid approach resolved complex features like the mitochondrial D-loop and deep evolutionary homology in plant chloroplasts where single-algorithm methods frequently were insufficient. Conclusions: In conclusion, CGCT bridges the gap between global structure and local sensitivity, offering a comprehensive solution for circular genome analysis. By layering multi-algorithmic outputs into a single topology-aware framework, it enables researchers to reconstruct accurate evolutionary narratives and discover novel features without requiring advanced bioinformatics expertise.

Background: Physical inactivity remains a major global public health concern and is a key modifiable risk factor for non-communicable diseases such as cardiovascular disease, diabetes and obesity. Although the benefits of regular physical activity are well established, many adults fail to meet recommended aerobic and muscle strengthening guidelines, particularly those living with chronic disease. Home-based exercise strategies may help overcome common barriers such as time constraints, accessibility, and low motivation. Active Video Games (AVGs) offer a potentially engaging alternative. However, many existing AVGs do not provide sufficient exercise intensity to elicit meaningful cardiovascular or metabolic benefits. Ring Fit Adventure (RFA) is a commercially available AVG for the Nintendo Switch that integrates aerobic and resistance exercise through whole-body movements. It has the potential to increase physical activity levels yet evidence evaluating its physiological effects in adults with chronic disease remains limited. Objective: This study aimed to investigate the acute physiological responses to playing RFA in adults with chronic diseases. It examined changes in heart rate (HR), blood pressure (BP), blood glucose (BG), exercise intensity, and perceived exertion, as well as enjoyment levels during gameplay. Methods: A cross-sectional observational pilot study was conducted involving 20 adults aged 40–65 years with at least one chronic disease (hypertension, hyperlipidaemia, diabetes, or obesity). Participants completed two stages (“World 1” and “World 2”) of Ring Fit Adventure following baseline assessment and a familiarisation session. Heart rate was continuously monitored using a chest strap, while BP, BG, oxygen saturation, and rate of perceived exertion (RPE) were measured at baseline and after each stage. Enjoyment was assessed using the Exergame Enjoyment Questionnaire. Statistical analyses compared baseline and post-exercise physiological measures. Results: All participants completed the protocol without adverse events. Mean continuous HR during gameplay reached 67.2% of age-predicted maximum, indicating moderate-intensity exercise, with peak HRs reaching vigorous-intensity levels (83.5% of maximum). HR and RPE increased significantly after both game stages (P<.01). Blood glucose levels decreased significantly following gameplay, with larger reductions observed among participants with diabetes, and no hypoglycaemic events recorded. No significant changes in systolic or diastolic BP were observed post-exercise. Enjoyment levels were high, with a mean score of 77.6 out of 100. Conclusions: Ring Fit Adventure elicited safe and clinically meaningful moderate-to-vigorous intensity exercise in adults with chronic diseases, alongside favourable acute reductions in blood glucose and high enjoyment levels. These findings suggest that RFA may serve as a viable and engaging home-based exercise modality to support physical activity participation and chronic disease management. Further longitudinal research is warranted to assess long-term adherence and health outcomes.

Background: Myopia is a growing global public health concern, with particularly high prevalence among school-aged children in East and Southeast Asia and increasing risk of sight-threatening complications in high myopia. Early identification of premyopia is critical for timely intervention, yet current screening methods rely on specialized equipment or static imaging and fail to capture dynamic near-work behaviors, limiting accessibility and scalability. Therefore, an accessible and behavior-aware screening approach is urgently needed. Objective: To validate a smartphone-based machine learning (ML) method for home myopia screening in school-aged children, focusing on translational utility in resource-limited settings and premyopia detection, addressing gaps in static tools. Methods: A total of 150 school-aged children (6–18 years) were enrolled for ML model training/validation, with 54 additional eyes for preliminary external testing. Sample size was justified via power analysis. Smartphone-acquired features included age, sex, pupil distance, eye-screen distance, and cohesion angle. Pixel-to-distance calibration and measurement repeatability were validated. Stratified tenfold repeated cross-validation and bootstrapping assessed model stability. ML models predicted spherical equivalent (SE) and classified myopia (SE≤-0.50 D) vs. premyopia (SE: -0.50 D to +0.75 D); SHAP quantified feature importance. Results: Participants (mean age 9.24 ± 2.23 years) had a 61.3% myopia rate. Eye-screen distance was the top feature (importance=1.00). Random forest performed best: SE prediction (test set: R²=0.523, 95% CI 0.237–0.802; MAE=0.686 D, 95% CI 0.480–0.890) and myopia classification (test set: AUC=0.855, 95% CI 0.716–0.976; accuracy=0.779). Bootstrapped CV <10% confirmed stability. Intra-session ICC for eye-screen distance and cohesion angle was 0.91 and 0.89, respectively, indicating excellent repeatability. Conclusions: This smartphone-based ML method reliably screens for myopia/premyopia at home, with strong translational potential for national myopia control programs, especially in resource-limited regions. Multicenter longitudinal studies will enhance generalizability and clinical translation.

Background: Quality of life (QoL) plays a crucial role in dementia care, yet QoL and its dynamic, context-dependent nature can be difficult to capture in people living with dementia due to challenges in memory and communication and limitations of self-reported QoL instruments. Observational tools such as the Maastricht Electronic Daily Life Observation (MEDLO) provide narrative descriptions of the daily life of people living with dementia in nursing homes. However, the MEDLO tool was not developed to assess QoL specifically, and it remains unclear to what extent its narrative descriptions reflect aspects of QoL. Analysing these narrative descriptions is labour-intensive and time-consuming. Recent advances in natural language processing (NLP), including Large Language Models, offer potential to analyse these narrative descriptions at scale. Objective: The study aims to gain insight into the QoL in people living with dementia residing in nursing homes in the Netherlands, using NLP to interpret narratives of daily life in existing MEDLO data. Methods: This study conducted a secondary analysis of existing MEDLO observational data from 151 people living with dementia residing in Dutch long-term care. Narrative data had been documented by trained observers, describing activities, interactions, settings and emotional expressions. For analysis, a local secure pipeline was developed in which GPT-4o-mini was deployed for NLP tasks. The pipeline comprised three analytical steps: (1) N-gram frequency analysis to identify common language patterns, (2) sentiment analysis of positive and negative expressions per QoL domains, and (3) topic modelling to group semantically related terms and map them to QoL domains. Outputs were iteratively refined through prompt engineering and validated through expert review for coherence and contextual relevance. Results: A total of 5,622 narratives (50,106 words) from 151 observed people living with dementia were analysed. The narratives were short, averaging 8.5 words per narrative. N-gram frequency analysis identified frequent documentation of passive activity (sits at the table) in limited indoor settings (living room). Emotional well-being was often described in positive terms (smiles, laughs), whereas explicitly negative expressions (cries, distress) occurred less frequently. Weighted sentiment analysis showed that, although fewer in number, negative expressions carried a stronger intensity, resulting in an overall predominance of negative sentiment across all QoL domains. Topic modelling identified eight coherent clusters, most of which mapped onto multiple QoL domains, underscoring QoL’s multidimensionality. Conclusions: NLP identified predominantly passive activities in little varying indoor settings, yet people living with dementia were often described with positive affect, underscoring both the complexity of QoL in dementia and the influence of documentation practices. In practice, NLP could help translate everyday care documentation into actionable information that guides more responsive, person-centred dementia care.

Background: As psychological practice becomes increasingly digitalized, the demand for competencies in digital psychology is growing. Although competency frameworks for digital clinical practice exists, validated instruments to assess these competencies remain scarce. In Sweden, psychology master’s students are now being offered courses in digital clinical psychology, increasing the need for instruments to measure intended improvements in knowledge and abilities. Using artificial intelligence (AI) to assist translation procedures can facilitate the adaptation of existing instruments to new national and cultural context. Objective: To test an AI-assisted procedure for the translation and contextual adaptation of the Digital Competencies for Applied Psychological Practitioner (DCAPP) scale to Swedish. To examine the psychometric properties of the translated version on a sample of psychology master’s students in Sweden, including pilot testing of the instruments responsiveness to change in knowledge and abilities among students attending a course in digital clinical psychology. Methods: An AI-assisted adaptation procedure, using ChatGPT and DeepL, was used to translate the DCAPP from English to Swedish. The Swedish version was distributed to psychology master’s students during their eighth semester, including those attending an elective course in digital clinical psychology. Twenty-four students completed the baseline measurement. Nine out of 14 students that attended the course also provided data at follow-up. Item descriptives, internal consistency and responsiveness to change were calculated for the scale. Results: The AI-assisted translation procedure resulted in a translated version of the scale with both high quality and semantic similarity ratings. The Swedish DCAPP demonstrated excellent internal consistency for total score (α = .96), and also for knowledge (α = .93) and ability (α = .96) subscales. It demonstrated acceptable item distributions with item-total correlation above .30 (range: 0.53-0.87) and mean-item correlation for subscales were acceptable but indicated potential item redundancy (Knowledge r=.48; Abilities r=.61). Whilst skewness and kurtosis values were mostly acceptable, high floor effects were observed in both subscales. A statistically significant increase in students’ competency ratings was observed at post-test (P<.001), suggesting good sensitivity to change. Conclusions: Using an AI-assisted adaptation procedure to support translation is feasible. The Swedish DCAPP showed promising psychometric properties and preliminary evidence of responsiveness to change. Floor effects may have been due to students limited digital competencies. Although initial results are promising, further research with larger samples is needed before the Swedish DCAPP’s psychometric validity can be confirmed.

Background: Smartwatches can be of added value in mental healthcare, by giving insights into activity and sleep of patients, which are fundamental aspects of daily functioning that are strongly linked to mental health. However, their implementation in mental healthcare practice remains limited. Professionals can feel resistance towards digital mental health interventions if they feel their use is not aligned with therapeutic values, and report a need for guidance on how to use technologies in ways that do align with such values. Compassion, a core value in mental healthcare, may provide a meaningful frame for implementation. Therefore, we previously co-designed compassion-focused implementation materials: a card set offering practical suggestions of how smartwatch data can support group treatments in ways that counter the self-optimization logic of commercial devices and instead align with compassion. Objective: The current study evaluated the compassion-focused card set in practice, to explore whether the introduction of the card set influenced the use of smartwatches, experienced compassion when using the smartwatches, the therapeutic alliance and the acceptance of smartwatches in social psychiatric nurses. Methods: The card-set was evaluated in a mixed-methods replicated single-case design with five social psychiatric nurses from an acute mental healthcare team. Data collection included pre- and post-questionnaires, repeated measures, a focus group, and interviews. Results: Quantitative results showed no consistent significant improvements in compassion, therapeutic alliance, or the acceptance of smartwatches. However, smartwatch use started or increased temporarily after the introduction of the card set. Qualitative findings indicated that the card set was experienced as flexible and easy to use, supporting session structure and enabling more in-depth, compassionate conversations. At the same time, barriers to sustained smartwatch integration included low patient uptake, challenges in mixed groups in which only some patients wore the smartwatch, and varying digital affinity among professionals. Conclusions: These findings suggest that compassion-focused materials may trigger initial adoption and help reframe smartwatch use in line with therapeutic values. Broader implementation strategies, including further training and tailoring to patient readiness, are required for sustainable integration.

Background: The introduction of pneumococcal vaccination programmes in the UK has led to substantial reduction in the burden of pneumococcal disease in the general population, decreasing the incidence of invasive pneumococcal disease (IPD) and preventing associated mortality. Objective: We aim to evaluate the yearly uptake of pneumococcal vaccine in adults who are included in national recommendations as people with immunosuppressive conditions, stratified by aetiology of immunosuppression. Methods: This will be a retrospective cohort study with data from the Oxford-Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) network, which is nationally representative of the English population.
The population are adults registered in the RSC database with immunosuppression, including those with bone marrow compromise, solid organ transplant, receiving oncological treatment, using immunosuppressive drugs, or with primary or acquired immunodeficiencies. The exposure is the underlying medical condition leading to an immunosuppression category. The primary outcome will be pneumococcal vaccination, defined as one dose of PPV23.
Vaccination rates will be calculated using the number of vaccinated people in high-risk groups as the numerator and estimates of the total high-risk population in the RSC dataset as the denominator. We will compare amongst vaccinated and unvaccinated people, and across immunosuppressive aetiologies using descriptive statistics, with pairwise comparisons using standardized mean differences. Results: We will report pneumococcal vaccine uptake disaggregated for the high-risk group of people with immunosuppressive conditions, which have not been previously reported. We will report on the socioeconomic gradient for vaccine uptake, through the use of the index of multiple deprivation score and region; report on the differences amongst ethnic groups; and report on vaccination uptake during the COVID-19 pandemic period.
We will curate an ontology for immunosuppressive conditions, contributing to CMR research following the open science frameworks for reproducible research. Conclusions: We will inform on the granularity of routine primary care data to include disaggregated reports of vaccine uptake in the immunosuppressed population in routine surveillance in the UK.
This will aim to address the gap on pneumococcal vaccination coverage in people with immunosuppressive conditions, helping to identify potential unwarranted variations in vaccine adoption.

Background: Advanced HIV Disease (AHD), caused by the human immunodeficiency virus (HIV), remains a significant global health concern, with nearly 40.8 million people living with HIV (PLHIV) as of 2024. Antiretroviral therapy (ART) has improved outcomes, yet its success depends on timely interventions, adherence, and retention in care. Artificial intelligence (AI), including machine learning and deep learning algorithms, offers promising tools for prognostic modeling in HIV care, supporting clinical decision-making and personalized treatment. Recent evidence has reported a wide range of AI applications across the HIV care continuum. However, existing syntheses have largely adopted broad narrative approaches and have not focused specifically on AI-based prognostic prediction models or systematically evaluated their performance, risk of bias, reporting quality, and clinical readiness. Consequently, a critical gap remains in understanding the validity, robustness, and applicability of AI-driven prognostic models for PLHIV. Objective: The present study aims to conduct a systematic review and meta-analysis of AI-based prognostic models predicting treatment and disease outcomes among PLHIV, with a focused assessment of predictive performance, methodological rigor, reporting transparency, and potential for clinical implementation. Methods: A comprehensive literature search will be performed across six databases – PubMed, Embase, Scopus, Web of Science, IEEE Xplore, and ACM Digital Library, covering studies published from January 2015 to December 2025. Eligible studies included original research using AI to predict individual-level outcomes among PLHIV. The study is registered with PROSPERO (Registration number: CRD420251034551) and follows TRIPOD-SRMA guidelines.
Data extraction will follow a standardized form based on the CHARMS Checklist and extended with elements from PROBAST, TRIPOD-AI, DECIDE-AI, and the NeurIPS Paper Checklists. Risk of bias, reporting transparency, implementation, and reproducibility will be assessed using these tools. When feasible, prognostic accuracy metrics (e.g., AUC, sensitivity, specificity) will be synthesized using random-effects meta-analytic models, including bivariate analysis and hierarchical summary receiver operating characteristic (HSROC) curves. Heterogeneity will be assessed and explored through subgroup analysis and meta-regression. The strength of evidence will be graded using an adapted GRADE framework that incorporated AI-specific quality dimensions. Results: The search for this systematic review and meta-analysis started in January 2026 and the results are expected to be published at the end of the year. It is expected to identify a wide range of AI-based prognostic models across the HIV care continuum. The findings are anticipated to reveal substantial heterogeneity and common methodological and reporting limitations, including issues with transparency, reproducibility, and risk of bias. Conclusions: This review will provide a focused and methodologically rigorous synthesis of AI-based prognostic models in HIV care, identifying models with robust predictive performance and highlighting critical gaps in validation, reporting, and clinical readiness to inform best practices for future development and implementation.

Modern hospitals require stable connections between medical devices and electronic health record systems for optimal patient care. Devices including fetal monitors, anesthesia machines, infusion pumps, and cardiac implants must reliably transmit patient data to clinical documentation systems. Technical or infrastructure failures affecting these connections force clinicians to document manually and lose real-time data access. Research attributes 22.5% of EHR safety events to health IT failures, often originating from interface errors. This viewpoint presents an engineering framework, derived from hands-on operational experience with device connectivity systems in varied healthcare settings, for analyzing medical device integration failures. The analysis combines firsthand experience with targeted literature review to identify common failure modes in fetal monitoring, anesthesia integration, infusion pump connectivity, and cardiac device data transfer. The framework identifies five main architectural layers vulnerable to failure: the medical device layer, data aggregation layer, interface/translation layer, EHR integration layer, and clinical presentation layer. Recurring failure patterns include full system outages, application errors, and degraded performance, with system outages predominating. A significant proportion of failures self-resolve, suggesting underlying system instability requiring investigation. Solutions range from restarting services to advanced reconfiguration and vendor support. Legacy system dependencies, inadequate monitoring, and gaps between system design and actual clinical workflow drive integration failures. Healthcare organizations should consistently monitor device feeds, establish alternate data pathways where feasible, and maintain clear downtime procedures to manage failures effectively.

Background: Traditional Problem-Based Learning (PBL) in pediatric nursing education often uses static cases and lacks personalized, real-time feedback. The integration of generative AI like ChatGPT could address these limitations, yet its systematic application in nursing internships remains understudied. Objective: To explore the effectiveness and feasibility of a ChatGPT-assisted Problem-Based Learning (PBL) model in pediatric nursing undergraduate internship education, providing empirical evidence for artificial intelligence(AI) nursing education integration. Methods: A single-center, assessor-blinded randomized controlled pilot study was conducted. Eighty-four interns were randomly assigned to the ChatGPT-PBL group (n=42) or traditional PBL group (n=42) at a 1:1 ratio. Based on traditional PBL, the experimental group integrated ChatGPT-4 to construct a "instructor-student dual-layer" supported PBL teaching framework, including dynamic generation of personalized clinical cases, provision of real-time operational feedback, and decision-making simulation training. The traditional PBL group received standardized traditional PBL teaching. The intervention lasted for 4 weeks. The primary outcome measures included theoretical assessment scores, Objective Structured Clinical Examination (OSCE) scores, Chinese Version of Critical Thinking Disposition Inventory (CTDI-CV) scores, Holistic Clinical Assessment Tool for Nursing Undergraduates (HCAT) scores, and teaching satisfaction. Results: Post-intervention, the theoretical score of the ChatGPT-PBL group was significantly higher than that of the traditional PBL group (82.76±5.02 vs 71.88±5.88, P<0.001). The ChatGPT-PBL group also showed significant advantages over the traditional PBL group in OSCE total score (43.24±2.75 vs 36.99±3.71, P<0.001), CTDI-CV total score (60.14±5.21 vs 49.87±5.74, P<0.001), and HCAT total score (51.14±3.46 vs 41.88±4.71, P<0.001). The overall satisfaction rates of the ChatGPT-PBL group with Instructors, teaching plans, and teaching content were 90.5%-95.2%, which were significantly higher than those of the traditional PBL group (64.3%-71.4%,<0.05). Conclusions: The ChatGPT-assisted PBL teaching model significantly improves the theoretical knowledge level, specialized operational skills, critical thinking ability, and clinical nursing competence of pediatric nursing undergraduate interns, with higher teaching satisfaction. It provides a replicable practical paradigm for the in-depth integration of AI and pediatric nursing education, and holds important clinical application and promotion value. Clinical Trial: The study protocol was registered in the Chinese Clinical Trial Registry (ChiCTR2500114150) .

Background: Digital technology is increasingly being used to deliver interventions and initiatives to support the wellbeing of older adults. However, few studies have conducted needs assessments to identify the future wellbeing service requirements of an older adult population and their preferred modes of delivery, whether via digital technology or in-person, or a combination of both (ie, a hybrid model). Objective: This study aims to investigate the requirements of a rural region in New Zealand to inform planning to meet the future wellbeing needs of its older adult population over the next 30 years Methods: In total, two focus group discussions and 10 interviews were held with participants using a combination of phone and video. A total of 33 adults aged ≥57 years participated. The participants were asked how they saw the future wellbeing needs of the older adult population evolving, the role of digital technology and/or in-person interactions to deliver wellbeing services, and perceived barriers to, and enablers of, digital technology for providing services. Focus group and interview transcripts were thematically analysed. Results: A total of 4 key wellbeing themes were identified across both focus group discussions and interviews with participants: “skills”, “services”, “spaces” and “social connection.” Each theme reflects the older adults’ interview responses in relation to questions about their demographic details and level of technology confidence. Conclusions: Results indicated that, within this rural regional population, older adults had limited understanding of, and low confidence in using digital technology. Although 57% of participants initially self-reported being very or somewhat confident using technology, most were unable to successfully engage in online focus groups. Meanwhile, digital technology is developing at a rapid pace, and as a result, we need to consider how to plan for the transition and bridge the gap identified between the current use of digital technology and its potential future use if technology is to support the older adults of the future. The findings indicate that older adults prefer to engage in-person, while trust is a barrier to digital technology use for some participants. The future offers many opportunities to support the wellbeing of individuals and communities through the application of the proposed 4 Ss Framework. Clinical Trial: N/A.

Background: Chronic opioid use, a key predictor of opioid overdose, is common among adolescents and young adults (AYA) with inflammatory bowel diseases (IBD), underscoring a need for tailored interventions to monitor opioid exposure and risk for opioid-related harm. Prior research also highlights the need to engage both AYA IBD patients and IBD-focused clinicians in development of pain management and opioid safety interventions. Human-centered design (HCD) offers a promising approach to address this gap by directly engaging patients and clinicians in co-creating solutions. Objective: As a foundational effort, we leveraged HCD to identify and define AYA patient and clinician perspectives to inform the design and development of a digital opioid safety intervention. Methods: We conducted semi-structured interviews with AYA IBD patients and IBD-focused clinicians (gastroenterologists, surgeons, and nurses). Interviews explored patient experiences with pain management, opioid use, and transitions to adult care, as well as clinician experiences in monitoring pain and prescribing opioids. A co-design workshop, following the interviews, brought patient and clinician participants together to reflect as a group on the unique challenges of managing pain in IBD care and consider potential creative solutions to enhance pain management safety. Data were audio recorded, transcribed, and thematically analyzed using an inductive approach to identify themes. Results: A total of 17 participants (four AYA patients and 13 clinicians) contributed to the study. Thematic analysis generated three domains of needs that an opioid safety intervention should address: (1) Intersecting Needs (i.e. relevant at the patient and clinician and/or health system levels), (2) Patient-Level Needs (i.e. relevant at the patient level only), and (3) Clinician- and Health System-Level Needs (i.e. relevant at the clinician and/or health system levels only). Intersecting needs included integrating opioid safety interventions into multidisciplinary chronic care, supporting AYA transitions to independence, and acknowledging individual patient differences. Patient-level needs included assessing lived experiences of pain routinely, setting clear expectations about pain management, and connecting patients with safe non-opioid alternatives. Clinician- and system-level needs included accounting for pain management received outside the IBD clinic; addressing gaps in information, education, and resources regarding opioid risk or pain management; and coordinating safety efforts across clinical teams. Conclusions: AYA patients with IBD and IBD-focused clinicians identified multiple needs, including integrating routine pain assessments, connecting patients with safe pain management strategies, and facilitating smooth AYA transitions to adult care. Incorporating these insights into the development of a digital opioid safety intervention may enhance alignment between patient and clinician expectations regarding safe pain management and opioid use. This study underscores the value of HCD in developing digital opioid safety tools that are practical, patient-focused, and effectively integrated into clinical workflows. Findings can guide future intervention design, prototyping, and testing with continued engagement of AYA IBD patients and clinicians.

Background: Following the COVID-19 pandemic, telehealth has emerged as a potential tool to improve access to HIV prevention services like Pre-Exposure Prophylaxis (PrEP). However, data on its acceptance among PrEP users in Italy remains limited. Objective: Aim of this study is to assess attitudes toward telemedicine among PrEP users in a monocentric Italian cohort. Methods: A cross-sectional survey was conducted at a Padua University Hospital PrEP clinic from April to October 2024, consecutively recruiting 450 attendees. Participants completed an adapted, validated questionnaire evaluating willingness, perceived benefits, and concerns regarding telehealth. Associations with demographic and clinical variables were analyzed using multivariate linear regression and clustering techniques Results: The cohort was predominantly composed of men who have sex with men (MSM) (90.4%), was largely Italian (92.2%), and included 54.7% of participants under 40 years of age. Most participants (62.4%) reported using on-demand PrEP. Positive attitudes toward telemedicine were significantly associated with higher educational attainment, having a partner living with HIV, and a history of sexually transmitted infections. In contrast, older age and lack of access to appropriate communication tools were associated with lower perceived benefits and greater concerns regarding telemedicine. No significant associations were observed with distance from the hospital or nationality. Conclusions: Telehealth for PrEP delivery was widely accepted in this cohort, particularly among younger, digitally equipped MSM. The findings suggest TelePrEP could be a useful complementary tool to traditional clinic visits. However, acceptability must be further explored in more diverse and vulnerable populations to ensure equitable service delivery.

Background: While Evidence-Based Medicine (EBM) is a fundamental pillar of modern healthcare, its implementation into general practice is often hindered by time constraints, resource deficits, and the inherent complexity of primary care. This challenge is further exacerbated by a lack of consensus on EBM instruction, highlighting a critical need for standardized educational frameworks. Objective: To systematically synthesize intervention studies evaluating the effectiveness of EBM training, including EBM skills, and the impact of EBM on reactions, behavioral changes, attitudes, and practices among general practitioners and residents in family medicine. Methods: We conducted a systematic synthesis of interventional studies that used the Fresno test to assess EBM skills among residents or general practitioners after educational interventions (lectures, workshops, journal clubs, or e-learning program). A comprehensive search was performed across the Cochrane Library, Embase, and Medline databases for records published between January 1980 and July 2025. Study quality was assessed using the Modified Medical Education Research Study Quality Instrument (MMERSQI), and risk of bias was evaluaAmong the 200 records screened, eight studies involving 431 participants (residents and general practitioners) met the inclusion criteria. Study designs included one randomized controlled trial, six before–after studies, and one cross-sectional study. Mean methodological quality (MMERSQI) was 65.3 (SD 7.2). One study had a low risk of bias, five had a moderate risk, and two were rated as presenting with a high risk of bias, mainly due to confounding factors and selection into analysis. Six studies reported significant improvement in Fresno test scores after training, with mean score increases ranging from 4% to 60% (p<0.05), and two found no significant change. The greatest benefits were achieved after interactive or clinically integrated sessions combining lectures, workshops, or journal clubs. Participants reported higher confidence in applying EBM (+3.2 points on the Likert scale) and greater engagement with research (+2.5 hours of reading and 3.5 additional articles per week). ted using RoB 2 for randomized studies and ROBINS-I v2 for non-randomized studies. Owing to study heterogeneity, results were synthesized qualitatively. Results: Among the 200 records screened, eight studies involving 431 participants (residents and general practitioners) met the inclusion criteria. Study designs included one randomized controlled trial, six before–after studies, and one cross-sectional study. Mean methodological quality (MMERSQI) was 65.3 (SD 7.2).

Participants reported higher confidence in applying EBM (+3.2 points on the Likert scale) and greater engagement with research (+2.5 hours of reading and 3.5 additional articles per week). Conclusions: EBM training for residents and general practitioners improves both knowledge and practical application of evidence-based skills, particularly when it is interactive or clinically integrated. Evidence remains limited regarding long-term retention and patient-related outcomes.

Background: Consistent physical inactivity among adults and adolescents poses a major global health challenge. Mobile health (mHealth) interventions, particularly Just-in-Time Adaptive Interventions (JITAIs), offer a promising avenue for scalable and personalized physical activity promotion. However, developing and evaluating such adaptive interventions at scale, while integrating robust behavioral science, presents methodological hurdles. Objective: The PEARL study aimed to assess the feasibility and effectiveness of a reinforcement learning (RL) algorithm, informed by health behavior change theory (COM-B), to personalize the content and timing of physical activity nudges via the Fitbit app compared to fixed and random nudging strategies, and to a control group with no nudges. Methods: We conducted a large-scale, four-arm randomized controlled trial (RCT) enrolling 13,463 Fitbit users. Participants were randomized to: (1) Control (no nudges); (2) Random (random content/timing); (3) Fixed (logic based on baseline COM-B survey); and (4) RL (adaptive algorithm). The primary outcome was the change in average daily step count from baseline to 2 months. Secondary outcomes included user engagement and survey responses regarding capability, opportunity, and motivation. Results: 7,711 participants were included in the primary analysis (mean age 42.1 years; 86.3% female). At 1 month, the RL group showed a significant increase in daily steps compared to Control (+296 steps, P<.001), Random (+218 steps, P=.005), and Fixed (+238 steps, P=.002) groups. At 2 months, the RL group sustained a significant increase against the Control (+210 steps, P=.01). Generalized estimating equation (GEE) models confirmed a sustained significant increase in the RL group (+208 steps, P=.002). In exit surveys, the RL group reported higher favorable responses regarding nudge customization (37%) compared to other groups. Conclusions: This study demonstrates the feasibility and early efficacy of using RL to personalize digital health nudges at scale. While long-term retention remains a challenge, the adaptive approach outperformed static behavioral rules, showcasing the promise of dynamic personalization in a real-world mHealth setting.

Background: Due to surgical trauma and the impact of the disease, patients undergoing thoracic surgery often experience a series of postoperative symptom burdens, which affect their recovery. Traditional perioperative care has drawbacks. Objective: To evaluate the impact of an AI-based personalized smart nursing ward management model on postoperative recovery outcomes in patients undergoing thoracic surgery. Methods: According to patients' admission sequence, patients who met the inclusion criteria were divided into a control group (n=303) and an intervention group (n=240). The control group adopted the routine nursing mode of general wards, while the intervention group implemented the AI-based personalized smart nursing ward management model on the basis of the routine nursing provided to the control group. Results: Data from all 543 enrolled patients were analyzed. Compared with the control group (n=303) receiving routine care, the intervention group (n=240) had a significantly shorter median hospital stay (9.0 days vs 12.0 days) and chest tube indwelling time (5.0 days vs 7.0 days), as well as lower total hospitalization costs (¥61,032.87 vs ¥72,859.90) (all P < .001). The postoperative pulmonary complication rate was also significantly lower in the intervention group (3.8% vs 12.2%, P < .001). Furthermore, patient satisfaction was higher (98.53% vs 91.28%), and nurses' daily step count was reduced (12,359.52 vs 18,692.74 steps) in the intervention group (both P < .001) Conclusions: The AI-based smart nursing model effectively promotes postoperative recovery and offers an innovative management approach for thoracic surgery.

Background: The current global breastfeeding landscape presents both progress and challenges. The rise of artificial intelligence (AI) has emerged as a promising new strategy to enhance breastfeeding practices. Objective: To evaluate the impact of AI-driven tools on breastfeeding practices and outcomes. Methods: We searched PubMed, Web of Science, Cochrane Library, Embase, and CINAHL from inception to October 2025 for randomized controlled trials (RCTs) and quasi-experimental studies. The risk of bias in individual studies was assessed using the Cochrane risk of bias tool for randomized controlled trials (RoB 2) and the risk of bias in non-randomized studies of interventions tool (ROBINS-I). Data were extracted independently by two reviewers and combined using Review Manager 5.4 and R-4.5.2 to obtain pooled results via random-effects models, with subgroup analyses based on intervention type, timing of implementation, population characteristics, and country income level. Results: This review included 39 studies with 10735 participants from 15 countries. AI-driven tools increased exclusive breastfeeding (EBF) rates (at <3 months: relative risk [RR] 1.21, 95% CI 1.13-1.29; P<.001, I²=56%; at 3–6 months: RR 1.54; 95% CI 1.29-1.85; P<.001, I2=69%; at ≥6 months: RR 1.47, 95% CI 1.22-1.77, P<.001, I2=78%), breastfeeding self-efficacy (BSE) (standardized mean difference [SMD] 0.41, 95% CI: 0.04-0.78; P=.03, I2=93%), and breastfeeding knowledge (SMD 1.69; 95% CI: 0.54-2.84, P=.004, I2=98%). Conclusions: AI-driven tools effectively increase exclusive breastfeeding rates, breastfeeding self-efficacy, and breastfeeding knowledge. Future studies are needed to provide stronger evidence about clinical care interventions. Clinical Trial: PROSPERO CRD420251233352; https://www.crd.york.ac.uk/PROSPERO/view/CRD420251233352

Background: Understanding how digital systems can support clinical decision-making is crucial, especially with the growing deployment of increasingly complex artificial intelligence (AI) models. This complexity raises concerns about trustworthiness, impacting the safe and effective adoption of such technologies. In intensive care units (ICUs), where clinicians make high-stakes, time-sensitive decisions, decision-support tools must be designed to align with clinical needs and cognitive workflows. Improved understanding of decision-making processes and requirements for decision support tools is vital for providing effective solutions. Objective: This study aimed to investigate ICU clinicians’ decision-making processes, the challenges posed by patient complexity, and the requirements for decision-support systems to ensure transparent and trustworthy recommendations. Methods: We conducted group interviews with seven ICU clinicians, representing diverse roles and experience levels, to explore perspectives on decision-support tools. Reflexive thematic analysis was used to identify key themes and thereafter design recommendations. Results: Three core themes emerged from the analysis: (T1) ICU decision-making relies on a wide range of factors; (T2) patient complexity challenges shared decision-making, and (T3) acceptability and usability of decision support systems. Design recommendations derived from clinical input provide insights to inform future decision support systems for intensive care. Conclusions: Decision-support tools have the potential to enhance ICU decision-making, but their adoption depends on alignment with clinicians' needs and workflows. To improve trust and usability, future systems must be transparent in their recommendations, adapt to varying patient complexities, and facilitate, rather than replace, human expertise. Our findings inform the development of digital systems that are both transparent and trustworthy, aiding clinically acceptance in ICU settings. Clinical Trial: Not applicable.

Background: Parkinson's clinical trials depend on patient-reported outcomes, often overlooking the vital role of carers in collaboratively tracking symptom progression. This is a potential limitation for decentralized clinical trials aimed at measuring real-world, free-living symptoms with sensors, such as wearables and cameras in the home. Objective: The primary objective of our study was to inform the design of a multimodal sensor platform for decentralised clinical trials. Methods: A qualitative study was conducted with an inductive approach using semistructured interviews with a cohort of people with Parkinson's. Results: This study of 18 participants (14 people diagnosed with Parkinsons, 4 spouses/informal carers) found that carers, household members, and peers take a central role in helping people with Parkinson’s make sense of and manage their symptoms. Our participants relied on others to help with completing tasks and understanding their symptoms through comparison to others, using their Carer-as-Sensor. While our participants mostly viewed their relationships with others positively, this could lead to negative impacts on oneself. Participants could prioritize household needs over their health by not taking medication or risking a chance of falling, or even avoiding being around others to prevent their Parkinson's being on display to reduce carer burden. Conclusions: Our results argue that an 'outsider' and 'insider' approach to reporting symptoms can identify symptoms that are not noticed by people with Parkinson's, or withheld from carers. These form household-centred recommendations more broadly for the design of tracking and annotation strategies in the context of decentralised clinical trials and new innovations in AI to support the capture of nuanced and subtle changes in symptoms.

Background: Pediatric-onset multiple sclerosis (POMS) is a chronic, progressive neurologic condition requiring lifelong management and coordinated transition from pediatric to adult care. Evidence-based guidelines identify transition readiness assessment as a core component of successful transition; however, most POMS clinics do not formally assess readiness, and existing tools do not address POMS-specific challenges, such as fluctuating disability, complex treatment regimens, and cognitive impairment. This gap underscores the need for a transition readiness measure tailored to POMS. Objective: To describe a stakeholder-engaged, implementation science–guided protocol for adapting the Transition Readiness Assessment Questionnaire (TRAQ) to reflect the unique developmental and clinical needs of youth with POMS. Methods: Using adaptation and participatory research as our guiding implementation strategies, surveys will be administered to patients, caregivers, and clinicians to identify barriers and facilitators to transition to adult care and define essential self-management competencies. Survey content will be informed by constructs from the Dynamic Adaptation Process framework and existing TRAQ domains. Identified competencies will be refined using a Delphi consensus process. A multidisciplinary focus group of 8–10 collaborators will review the adapted measure to assess clarity, relevance, and perceived clinical utility. Results: This project will generate a consensus-driven set of POMS-specific transition competencies and systematically adapt the TRAQ to the POMS population. Conclusions: This protocol outlines a rigorous, easily replicable approach to adapting a validated transition readiness measure to POMS. The adapted TRAQ will support evidence-based transition planning and inform future psychometric testing and implementation research to improve the care of POMS patients as they age.

Background: Intensive care clinicians rely on timely access to large volumes of electronic data to make complex decisions. The Central Adelaide Local Health Network (CALHN) implemented an electronic medical record (EMR) across its hospitals in South Australia, but the generic user interface is not optimised for critical care workflows. The CALHN Critical Care Informatics System (CCCIS) was developed as a prototype user interface (UI) to present ICU-relevant information in a more intuitive, task-focused format. Objective: This study aimed to evaluate the usability of CCCIS from the perspective of senior intensivists, and to identify key design principles for effective critical care informatics systems. Methods: We undertook a usability study with eight intensivists from CALHN. Participants interacted with a prototype version of CCCIS during a structured video-based session incorporating a Cognitive Walkthrough and Think Aloud approach. Sessions were screen-recorded and transcribed. Qualitative data were coded as positive, negative or neutral feedback and grouped into three domains: content, layout and visibility. Emergent themes were mapped across CCCIS components. Following the usability test, participants completed a System Usability Scale, NASA Task Load Index and a bespoke questionnaire assessing perceived usability, cognitive demand and clinical relevance. Reporting is aligned with the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines for interview-based research. Results: Participants reported that CCCIS supported rapid comprehension of patient information and facilitated integration between physiological data, interventions and clinical trajectory. The ability to customise views and to navigate between ward-level and bed-level information was highlighted as a strength. Areas for improvement included refinement of the ward board, ribbon and vital signs displays, particularly where duplicated information or visual clutter reduced clarity. Across the content, layout and visibility domains, recurrent themes included the importance of structured tabular displays, consistent visual hierarchies and explicit highlighting of clinically salient values. Survey responses suggested that CCCIS was easy to learn and use, exerted low cognitive demand, and was perceived as clinically relevant to everyday critical care practice. Conclusions: In this qualitative usability evaluation, intensivists perceived CCCIS as a usable and clinically meaningful critical care informatics system. The study identified design principles—such as structured presentation of data, alignment with mental models of ICU workflow and support for rapid synthesis of information—that may inform further development of CCCIS and other electronic medical record-integrated ICU interfaces.

Background: Gestational Diabetes is a disorder characterised by hyperglycaemia that is first recognised during pregnancy due to a mismatch between the placental hormones produced, causing insulin resistance. Few studies have systematically examined the metabolic pathways responsible for gestational diabetes from diagnosis to the postnatal period, including the metabolic changes in the placenta through metabolomics studies. Objective: This study aimed to evaluate the metabolites identified through metabolomics, as well as their associated pathways, responsible for hyperglycaemia in the gestational period across pregnancy and postpartum, compared to those without diabetes during pregnancy. Serum samples are taken at 24-28 weeks of gestation, followed by placental samples, cord blood, and postnatal serum samples between 4 and 12 weeks. Methods: Anthropometric data is collected at the first visit. Samples are collected at three points: serum or plasma samples at the time of diagnosis of gestational diabetes or the first visit after diagnosis, placental samples and cord blood samples during delivery, and during the postpartum period.
Macroscopic and microscopic features of the placenta are noted. The metabolic pathways between GDM and non-GDM mothers across pregnancy, starting from the diagnosis of gestational diabetes, and the changes in pathways in the placenta, cord blood, and postnatal blood will be compared. Results: The study was funded by an institutionally funded research grant in January 2025. Recruitment for the study began in June 2025 and is expected to be completed by June 2026. We plan to recruit 40 patients with GDM and age- and BMI-matched normoglycaemic controls. Conclusions: The findings from this study will provide insight into the various metabolites or biomarkers and their metabolic pathways involved in the pathogenesis of gestational diabetes across the life course of mothers, compared with those of normoglycemic mothers, and offer potential insight into the role of the placenta in gestational diabetes.

Background: Stroke represents a leading cause of global disability and mortality. In acute stroke patients, tracheotomy is often required for survival during the critical phase; however, weaning from the tracheostomy tube remains a major challenge in the recovery period. Prolonged dependence on the tube considerably impairs patients' quality of life. Previous research indicates that multiple environmental factors—including oxygen concentration, air humidity, and ultraviolet radiation—can influence cardiopulmonary function and airway adaptability. Moreover, high-altitude environments are known to alter hemoglobin oxygen-carrying capacity and induce adaptive genetic polymorphisms. Based on these observations, we hypothesize that residents living at different altitudes may demonstrate varying success rates of tracheostomy tube removal. Objective: This study aims to investigate whether altitude of residence affects extubation success rates by modulating adaptive mechanisms related to hemoglobin oxygen affinity and genetic factors (EPAS1/EGLN1). We further aim to develop a predictive model integrating environmental factors, genetic polymorphisms, and clinical data for estimating extubation success. Methods: The "Extubation Success After Tracheotomy in Stroke Patients at different Altitudes" (ESTATE) study is a prospective, multi-center cohort study (August 2025–December 2028). This initiative aims to enroll 900 tracheotomized stroke patients from Chinese regions stratified by altitude. After screening against strict criteria, participants will receive baseline assessments (demographics, clinical scales, hematological tests). All will undergo standardized rehabilitation, with outcomes—including extubation status and quality of life—assessed at discharge and at 1, 3, 6, 9, and 12 months post-discharge. Results: Initiated in August, 2025, this study has enrolled 25 participants to date. Recruitment will continue through 2027, with final follow-up and data analysis to be completed in 2028. The main findings are expected to Our research team aims to conduct an in-depth investigation into the association between successful extubation and the biological and genetic adaptations resulting from long-term residence at different altitudes in tracheotomized stroke patients.

Background: Brachial plexus birth injury (BPBI) occurs in approximately one of 1,000 live births resulting in long-term limitations in upper extremity function including shoulder contracture. Early intervention with passive range of motion (PROM) performed by caregivers multiple times per day is commonly recommended to prevent the development of shoulder contracture. Research shows that common barriers to adherence to this daily PROM recommendation includes caregiver lack of confidence and fear of hurting their child.
Objectives: 1) determine whether caregivers who receive a Coaching training protocol for performing PROM demonstrate improved efficacy in performing PROM compared to caregivers who receive standard training; and 2) determine whether caregivers who receive a Coaching training protocol for performing PROM demonstrate improved self-confidence in performing PROM compared to caregivers who receive standard training.
Methods: This prospective, multi-site randomized clinical trial will evaluate the efficacy of a caregiver training protocol that uses principles of coaching and guided discovery to enhance confidence and problem-solving needed to overcome barriers to adherence. Caregivers of infants with BPBI will be randomized to receive either standard PROM training or the Coaching-based protocol. Caregiver efficacy, self-reported self-confidence, self-reported frequency of performing PROM, and facilitators and barriers to adherence will be compared between the two groups. Findings will be used to determine whether the Coaching protocol is superior for facilitating caregiver efficacy and confidence and subsequently supports daily PROM adherence.
Conclusion: If effective, this protocol will be integrated into a larger non-inferiority trial to assess the minimum daily frequency of PROM needed to decrease the risk of shoulder contracture. This study addresses a critical gap in evidence-based standards for early intervention for infants with BPBI and aims to improve long-term functional outcomes for affected infants and their families.

Background: Personal Data Spaces (PDS) are increasingly promoted as digital infrastructures that enable citizen participation in health data governance by strengthening transparency and individual control over personal health data. Despite growing policy and technological attention, empirical evidence remains limited on whether citizens view PDS as acceptable and desirable governance instruments, how they evaluate different types of data and purposes of data use, and which factors shape public support. Objective: The objective of this study was to examine how citizens evaluate We Are, a proposed citizen-centered Personal Data Space model in Flanders, Belgium, and to assess overall support, reasons for endorsement, preferences for control versus transparency, acceptability of storing different types of health data, and acceptance of different purposes of data use. Methods: We conducted an online survey among adults aged 18-79 years in Flanders, Belgium (N=1,041). The sample was quota-based and representative for gender, age, education, province, and urbanization level. Participants evaluated the We Are model after reading a description. Measures included overall evaluation of the model, reasons for support, preferences for transparency and control, willingness to store medical versus lifestyle data, and willingness to share data across vignette-based scenarios varying purpose of use and recipient type. Data were analyzed using t-tests, linear regression, and mixed models with repeated measures. Results: Overall evaluations of We Are were moderately positive (Mean 2.51 on a 1-4 scale) and did not differ significantly from the scale midpoint (t(1040)=0.70, P=.24). Sociodemographic characteristics explained little variance in support, whereas understanding of the We Are model and psychographic factors substantially increased explained variance (R² increased from .03 to .24). Higher trust in technology was positively associated with support, while stronger privacy attitudes and privacy-related fears were negatively associated. Respondents valued control more strongly than transparency for both general personal data (t(1040)=-10.37, P<.001) and health data (t(1040)=-12.47, P<.001). Medical data were considered more acceptable to store than lifestyle data (Δ=0.38, P<.001). Both personal and public benefits motivated support, but commercial data use reduced willingness to share, particularly when framed around individual gain rather than collective benefit. Conclusions: Citizens view PDS as potentially valuable instruments for health data governance, but their support is conditional and shaped by understanding and psychographic factors rather than by sociodemographic factors. PDS can contribute to meaningful citizen participation only when technological features are embedded in governance arrangements that provide real agency, credible safeguards, and demonstrable public value.

The European Health Data Space represents a landmark regulatory success in enabling the secondary use of health data for research, innovation, and policy within a trusted and interoperable framework. This Viewpoint discusses how strategic alliances—such as UNINOVIS—and translational research ecosystems, with IBIMA as a driving hub, operationalize this regulation by aligning governance, infrastructure, and applied data science. Together, they illustrate how European health data policy can be translated into real-world evidence generation and sustained clinical and societal impact.

Background: Musculoskeletal conditions are a leading global cause of disability, yet the factors influencing long-term musculoskeletal health, particularly following trauma, remain incompletely understood. Machine learning could be applied to identify previously unknown patterns in large-scale multimodal datasets. Objective: Test the ability of a new sparse Group Factor Analysis method to uncover hidden patterns in large-scale multi-modal datasets and generate testable, clinically relevant hypotheses. Methods: This study applies sparse Group Factor Analysis, a hierarchical unsupervised machine learning method, to the ADVANCE cohort—a longitudinal dataset of 1445 UK Afghanistan War servicemen—to identify latent structures in multimodal clinical data. Study 1 validated the approach by rediscovering known group-level patterns between combat-injured and non-injured participants, including poorer outcomes in pain, mobility, and bone health among those with lower limb loss. Study 2 explored the Injured, non-amputee subgroup without prespecified labels to identify new hypothesis-generating clusters that could subsequently be tested using standard hypothesis testing methods. Results: A subgroup of 125 individuals with worse musculoskeletal outcomes was uncovered. This group had greater body mass, higher injury severity, and a higher prevalence of head injury. These findings led to a novel hypothesis: that head injury, including potential traumatic brain injury, is associated with long-term musculoskeletal deterioration. This hypothesis is supported by literature in both athletic and military populations and will be tested in follow-up analyses. Conclusions: Our findings demonstrate how sparse Group Factor Analysis, combined with clinical insight, can uncover hidden patterns in large-scale datasets and generate testable, clinically relevant hypotheses that inform prevention, treatment, and rehabilitation strategies.
Background: Chronic kidney disease (CKD) requires sustained self-management involving complex medication regimens, dietary restrictions, and symptom monitoring. These demands pose substantial challenges to medication adherence and daily disease management. Digital therapeutics (DTx) have the potential to support CKD self-management; however, CKD-specific design requirements informed by both patient and clinician perspectives remain insufficiently explored. Objective: This study aimed to identify key design requirements for CKD-specific digital therapeutics by integrating patient-reported self-management challenges with nephrologist perspectives on clinical needs and implementation considerations. Methods: A convergent mixed-methods study was conducted at a tertiary academic hospital. Quantitative data were collected through a structured survey of 60 adults with non–dialysis-dependent CKD to assess medication adherence challenges, digital health needs, and age-related differences. Qualitative data were obtained through focus group interviews with 19 nephrologists and analyzed using thematic analysis. Quantitative and qualitative findings were integrated to identify convergent priorities and design implications for CKD-specific DTx. Results: None of the patients reported prior experience with CKD-specific digital health applications, although 70% perceived a need for such tools. Younger patients (<60 years) expressed significantly greater interest in digital therapeutics than older patients (83.9% vs 55.2%, P=.015). Common patient-reported challenges included managing multiple medications (36.7%), irregular medication schedules (30.0%), and difficulty understanding medication timing relative to meals (28.3%). Nephrologists emphasized the importance of personalized medication reminders, comprehensive medication information (including adverse effects and nephrotoxic risks), symptom-monitoring systems, and features supporting dietary and lifestyle management. Integration findings highlighted the need for user-friendly, age-sensitive interfaces, data security, and clinically actionable feedback mechanisms. Conclusions: By integrating patient and nephrologist perspectives, this mixed-methods study identifies key design considerations for CKD-specific digital therapeutics. These findings provide formative, design-informed evidence to guide the early development of patient-centered and clinically relevant digital therapeutics for CKD.

Background: Progression-free survival (PFS) is a critical endpoint in oncology, yet real-world applications of individualised, explainable machine-learning (ML) predictions remain limited. Objective: This study aims to develop and validate explainable ML models to predict PFS using retrospective data from a national prostate cancer cohort in Brunei Darussalam. Methods: We analysed a retrospective cohort of 212 patients (478 longitudinal observations) treated at the Brunei Cancer Centre (January 2018 to December 2024). Clinical, laboratory, and treatment data were harmonised, with missing values imputed via Extremely Randomised Trees. Longitudinal patterns were captured using a recurrent autoencoder to generate latent representations. We compared four modelling approaches: Cox Proportional Hazards (CPH), Random Survival Forests (RSF), Gradient Boosting Survival (GBS), and Deep Neural Network Survival models. Performance was evaluated using time-dependent AUC, Harrell’s C-index, and Integrated Brier Score (IBS), with SHAP (Shapley Additive exPlanations) used for interpretability. Results: RSF demonstrated improved discriminative performance and balanced calibration, achieving a C-index of 0.906 and AUCs of 0.941 at both 4 and 5 years (IBS = 0.0698). In contrast, the traditional CPH model performed poorly (C-index 0.531; AUC 0.706 at 4 years). Deep survival (AUCs of 0.941 at 4 years and 0.941 at 5 years, C-index 0.719, IBS=0.0590) and GBS (AUCs of 0.765 at 4 years and 0.833 at 5 years, C-index 0.844, IBS=0.0887) models showed moderate performance. SHAP analysis identified sodium (Na), alanine aminotransferase (ALT), MCH, platelet count, and specific treatment categories as key drivers of increased progression risk. Conclusions: Tree-based ensemble approaches, particularly RSF integrated with SHAP, offer high accuracy for personalised risk stratification in prostate cancer. These findings highlight the potential of explainable ML to enhance clinical decision-making. However, external validation in larger multi-institutional, multi-omics dataset is required before routine clinical implementation.

Background: Clinical reasoning is a fundamental process that students must learn and be able to put into practice in medical school training. This requires the development of multiple abilities through practice with patients. Nevertheless, in contexts like emergency services the access is restricted for students. Virtual patients have shown to be a useful tool in the acquisition of knowledge and decision-making training for medical students. In recent years, large language models (LLMs) have emerged as an alternative that functions as conversational virtual patients allowing the students to refine their clinical reasoning abilities in a safe environment. Objective: The objective of our study was to evaluate the perception of medical students about PRAXIA in terms of communicative realism, case consistency, and its utility as a complementary pedagogical tool in medical student training. Methods: We employed a Design Thinking approach to develop PRAXIA, an LLM-based virtual simulation environment designed to enhance clinical reasoning. We assessed student performance using a custom rubric integrating the Revised-IDEA framework with the Dreyfus model of skill acquisition. Additionally, we designed a validation survey to measure communicative realism, story consistency, situational fidelity, feedback value, and technical usability. In a prospective study, 28 medical students from the Universidad de Chile completed a 10-minute simulated history and physical exam, followed by clinical decision-making tasks. Post-simulation, participants completed the user experience survey. We strictly observed data privacy and ethical standards. Results: Twenty-eight medical students from Universidad de Chile participated in the study and reported high overall satisfaction across all five prototype dimensions. Highest scores were for conversational realism (mean 3.58/4.00) and case coherence/consistency (mean 3.73/4.00 for both story consistency and situational fidelity), while the lowest was for formative feedback value (mean 3.29/4.00). Qualitative feedback from students estimated the experience as "useful," highlighting the virtual patient's fluency and human-like messages, but suggested the need for more specific feedback. Our psychometric analysis revealed acceptable to excellent internal consistency using the corrected item-total correlation (CITC). The "Formative value of the feedback" dimension demonstrated a Cronbach's alpha of 0.82, showing high internal consistency. Conclusions: PRAXIA, an LLM-based virtual patient for emergency medicine, shows high acceptability, educational value and promising usability. Its focus on realism, contextual fidelity, and formative feedback complements existing simulations and provides a basis for future studies on its effect on clinical reasoning.

Background: Thailand's accelerated population aging transformation, with 28% of citizens projected to reach 60+ years by 2030, requires innovative digital health solutions addressing family-centered care systems. Interconnected sensor networks, machine learning systems, and cloud-based analytics infrastructure present opportunities for revolutionizing elderly care provision, yet adoption patterns and implementation viability in Thai contexts remain underexplored. Objective: The objective of our study was to assess the viability and adoption patterns of interconnected sensors and machine learning technologies in Thai elderly care facilities, examining therapeutic effectiveness, user acceptance factors, and geographic preference variations. Methods: An integrated quantitative-qualitative methodology combining the Gerontechnology Adoption Framework (GTAF) and Service Exchange Value Creation Logic (SEVCL) was employed. Technology specialist assessments (n=12) and consumer evaluations across Bangkok and Chiang Mai (n=120) were conducted. Technology assessment followed digital health evaluation protocols incorporating user experience testing, data protection impact analysis, and healthcare workflow integration assessment. Quantitative examination included descriptive analytics, predictive modeling, and multi-criteria evaluation techniques, while qualitative information underwent systematic thematic examination. Results: Sensor-based fall prevention systems achieved superior therapeutic effectiveness scores (M=4.5/5.0, SD=0.3) with 89% adoption success metrics and favorable deployment complexity (M=2.8/5.0), demonstrating potential 25-30% emergency response cost reductions. Machine learning-powered early alert systems showed greatest clinical impact capability (M=4.7/5.0) with 30-35% hospitalization reduction potential and 76% user adoption despite deployment complexity (M=4.2/5.0). Digital health acceptance varied significantly by digital literacy levels, with high digital confidence participants showing 2.3x higher acceptance rates (p<0.001). Therapeutic gardens emerged as optimal sustainable intervention (M=4.8/5.0 benefit rating) correlating with 17% psychotropic medication reduction (r=0.78, p<0.001). Geographic preferences revealed Bangkok's preference for medical IoT technologies opposed to Chiang Mai's environmental digital solutions emphasis. Conclusions: Integrated smart technology implementation demonstrates simultaneous clinical outcome improvement and operational efficiency enhancement when properly configured for older adult populations. Success factors including phased IoT deployment, comprehensive digital health training, and human-technology balance respecting cultural values provide a systematic implementation framework for digital health transformation in elderly care settings across developing nations.

Background: Community-based interventions represent a strategic approach to integrating the salutogenic model, involving multi-sectoral stakeholders to improve the health of specific communities. In the context of the EU’s ageing population, eHealth technologies provide valuable solutions by improving older individuals' health and well-being through better access to knowledge, strengthening environmental relationships, and supporting the sustainability of health systems. This manuscript explores a community-based health promotion intervention focused on eHealth apps tested across six European regions within the GATEKEEPER project. Objective: Explore community-based health promotion interventions focused eHealth apps across six European regions within the GATEKEEPER project. Methods: An observational studies were conducted in the European regions of Basque Country (Spain), Aragon (Spain), Saxony (Germany), Puglia (Italy), Lodz (Poland), and Central Greece and Attica (Greece). Qualitative techniques were used to evaluate the implementation process, effectiveness of the community-based intervention, and user experience with the offered technologies. Results: Several factors influenced the success of the interventions, including the customisation and adaptation of applications to users' specific needs, the provision of incentives to promote engagement, and the support from health and community professionals. Customising apps to be user-friendly and culturally relevant ensures accessibility for diverse populations, while adaptation addresses varying levels of health literacy and digital skills. Continuous support from professionals fosters trust, reduces barriers to adoption, and promotes sustained engagement. Conclusions: This study provides insights into factors influencing adherence to digital health interventions. Understanding adherence, intention to use, and dropout rates is essential for identifying the factors contributing to the limited effectiveness of digitally-enabled real-world interventions. The findings stress the importance of co-designing interventions, ensuring user involvement from the beginning, which improves the alignment of technology with users' needs and increases engagement and effectiveness.

Background: Objective: To evaluate the efficacy of digital exercise therapy for pain relief in osteoarthritis (OA) patients.Methods: We conducted a systematic search of multiple databases for randomized controlled trials. Pain intensity was analyzed as the standardized mean difference (SMD) using a fixed-effects model in Stata. Methodological quality was assessed with the Cochrane RoB 2 tool. Results: Six trials (587 participants) were included. Digital exercise therapy significantly reduced pain (SMD = -0.28, 95% CI: -0.44 to -0.11; P = 0.001) with low heterogeneity (I² = 22.4%). Sensitivity analyses supported robustness. Conclusion: Digital exercise therapy significantly alleviates pain in OA. Despite limitations inherent to behavioral trials, it represents a viable and accessible treatment. Further large-scale, long-term trials are needed.

Background: Acute appendicitis is a common disease process typically requiring surgery, yet the workflow linking diagnostic imaging to surgical consultation varies substantially across emergency departments. Delays between imaging completion and consult acquisition may prolong care and contribute to avoidable clinical and operational inefficiencies. Objective: This study quantified real-world consultation delays for patients with radiology-confirmed appendicitis and evaluated the cumulative time impact on emergency department workflow. Methods: We performed a retrospective observational study of emergency department encounters from January 1, 2020, through December 31, 2025, in which abdominal imaging was obtained to evaluate possible appendicitis. All radiology impressions were manually adjudicated and classified as positive, indeterminate, or negative. The primary timing measure was the interval from imaging completion to surgical consultation order. Mann–Whitney U tests compared delays across imaging modalities and age groups. Logistic regression assessed predictors of prolonged delay (>30 minutes). Results: Among 1,422 encounters, 566 were classified as radiology-positive appendicitis. Surgical teams evaluated 565 of these patients (99.8 percent), demonstrating that positive radiology findings nearly always resulted in surgical involvement regardless of documentation of a formal consult order. Among 524 radiology-positive encounters with complete timestamps in a predefined plausible window (−60 to +360 minutes), the median time from imaging completion to consultation was 30.8 minutes (IQR 17.8–48.5). Delays were longer for CT than ultrasound (median 34.9 vs 21.2 minutes; p < 0.0001). CT was associated with prolonged delay (OR 2.29; 95% CI 1.08–4.86), while age group was not. Across a typical year, cumulative waiting time totaled approximately 58 patient-hours. Conclusions: Radiology-confirmed appendicitis reliably triggered surgical evaluation, yet meaningful delays remained. Standardizing and automating consult activation for clear radiologic diagnoses may reduce avoidable workflow variation and improve the timeliness of surgical care.

Background: Digital multidomain interventions hold promise for dementia risk reduction; however, populations at higher dementia risk, including those experiencing socioeconomic and educational disadvantage, remain underrepresented in trials, and engagement with digital interventions often declines over time. Co-production and blended models that combine digital tools with human support may improve reach, acceptability, usability, and sustained engagement. Designing interventions that are usable and acceptable for individuals facing structural, educational, or digital barriers (underserved groups) is therefore likely to produce solutions that are both accessible and scalable for the wider older adult population. Objective: To describe the co-production process used to develop ENHANCE—a coach-supported digital intervention targeting ten modifiable dementia risk factors in older adults from underserved groups—and report key outputs and lessons learned for equitable digital prevention design. Methods: We co-produced ENHANCE between July 2023 and February 2025 using a multi-stage development process guided by the Medical Research Council framework for complex interventions and the Double Diamond design model. The Person-Based Approach informed user-centred guiding principles (key design objectives), while behaviour change content was operationalised using behavioural change theories. Co-production followed four phases. The Discovery phase explored barriers to engagement with existing digital materials and identified candidate components for each dementia risk-factor module. The Define phase translated these insights into guiding principles and blueprints of each risk-factor module integrated with behavioural change components. The Design phase involved iterative co-production and usability testing of prototypes. The Delivery phase evaluated a high-fidelity prototype through a one-week usability study with coaching support. Contributors included 162 research participants recruited from underserved community settings, 33 patient and public involvement contributors, and 4 human–computer interaction experts. Throughout development, co-production focused on reducing literacy, digital confidence, and cultural barriers to maximise usability across diverse older adult populations. Results: Co-production produced (1) evidence-informed module strategies for targeted dementia risk factors; (2) a set of guiding principles to ensure low-literacy, culturally relevant, and accessible content, supporting both equity of access and wider population usability; (3) a meadow-themed app integrating tailored check-ins, educational videos, cognitive training games, and in-app messaging; and (4) a structured coaching model, including onboarding, brief follow-up, and accompanying coaching manuals. Iterative testing and refinement improved navigation, simplified language, reduced text burden, and ensured the use of familiar and accessible game formats, resulting in a feasibility-ready prototype. Conclusions: : ENHANCE is a co-produced, coach-supported digital intervention designed to be accessible for underserved older adults at increased dementia risk, with design features intended to support accessibility, engagement, and scalability across the wider ageing population. The development process illustrates how integrating co-production with behavioural science and usability methods can support principled intervention design for equitable digital dementia prevention.

Background: Medical interview training is a cornerstone of clinical education but faces resource limitations in both implementation and evaluation. While Generative Artificial Intelligence (GAI) offers a potential solution for assessment, it remains unclear whether reasoning models improve evaluation validity, particularly within the linguistic context of the Japanese language. Objective: To evaluate the validity of state-of-the-art GAI models in Japanese medical interview training, we assessed scoring patterns and agreement with human clinical educators. Methods: This preliminary comparative study was conducted at a medical university in Japan using text data derived from medical interview training, including both chatbot-based and traditional styles. Postgraduate year 1 and 2 residents were involved. Two blinded human clinical educators independently evaluated the transcripts, reaching a consensus score through discussion. The consensus score was the reference standard. Two GAI models, GPT-5.2 Thinking and Gemini 3.0 Pro, independently evaluated the same transcripts. All evaluations used a standardized 6-domain Objective Structured Clinical Examination rubric (patient care, history taking, physical examination, accuracy and organization of clinical information, clinical reasoning, and management) scored on a 1–6 Likert scale, where 1 is inferior and 6 is excellent. We compared mean evaluation scores using the Wilcoxon signed-rank test and assessed inter-rater reliability using Intraclass Correlation Coefficients (ICCs) between the GAI models and the clinical educators. Results: Clinical educators and both GAI models rated the entire dataset of 40 transcripts by 20 included residents. Clinical educators assigned the highest overall mean scores (5.18, 95% CI 5.06-5.30). Compared to clinical educators, both GAI models demonstrated significant score deflation: GPT-5.2 Thinking assigned the lowest overall score (3.68, 95% CI 3.62-3.72; P<.001), followed by Gemini 3.0 Pro (4.09, 95% CI 3.97-4.21; P<.001). This discrepancy was most pronounced in the management domain, where GPT-5.2 Thinking assigned 2.93 (95% CI 2.79-3.06) compared to the clinical educators' 5.20 (95% CI 4.91-5.49). Agreement between the GAI models and human raters was poor across all domains, with overall ICCs of 0.04 (95% CI 0.00-0.09) for GPT-5.2 Thinking and 0.22 (95% CI 0.10-0.35) for Gemini 3.0 Pro. Conclusions: Unlike previous iterations of GAI, which tended to overestimate student performance, GPT-5.2 Thinking and Gemini 3.0 Pro graded stricter than human experts. Due to significant score discrepancies and poor inter-rater agreement, these models currently lack the validity to serve as standalone summative evaluators for Japanese Objective Structured Clinical Examinations, although their rigorous detection of deficiencies may offer value for formative feedback.

Background: Cardiac rehabilitation (CR) improves patient quality of life, morbidity, and mortality. Unfortunately, it is underused by patients. Digital health interventions offer a solution to increase participation in CR. However, patients’ interest in virtual CR, especially among those in the inpatient setting, has not been fully explored. These benefits have been predominantly demonstrated in traditional, center-based CR programs. Objective: The objective of this prospective cross-sectional study was to explore inpatient interest in virtual cardiac rehabilitation among adult patients who were hospitalized with a cardiac rehabilitation-qualifying diagnosis. Methods: A Qualtrics survey, comprised of multiple-choice questions, was administered to cardiac inpatients at the progressive cardiac care unit at Johns Hopkins Hospital from January 2020 to March 2024. Sociodemographic and clinical characteristics were retrieved from the electronic medical record. The study included English-speaking patients over 18 years of age with a diagnosis eligible for CR. Results: A total of 150 patients were included (age 64 ± 13 years, 38% women, and 57% White). With respect to sociodemographic characteristics, 26% of the patients had a high school education or less, 47% were married, 26% were employed full-time, and 63% had private insurance. Participants with greater than high school education were more likely to perceive smartphones as beneficial for leading a healthier lifestyle (48.1% vs. 24.3%, p=0.01) and learning about illnesses (85.7% vs. 54.1%, p<0.001) than participants with a high school education or less. Participants across all sociodemographic factors expressed interest in virtual CR (overall 71.3%), with non-White participants being more interested than White participants (84.6% vs. 61.2%, p=0.002). Conclusions: The majority of cardiac inpatients expressed interest in home-based/virtual CR to alleviate barriers to in-person CR participation. Future work should emphasize digital equity and user support to optimize the widespread adoption of virtual CR.

Background: Mental health difficulties affect nearly one billion people globally. Many of these emerge during youth, making early intervention crucial. Vietnam and Cambodia both have young populations, recent histories of conflict and ongoing vulnerabilities, including poverty and urban-rural inequality. Although many children and young people (CYP) experience common mental disorders, access to care is limited by stigma, low mental health literacy and reliance on medicalised, urban-centred services. Building the capacity of community-based stakeholders to deliver mental health interventions offers a promising strategy for health systems strengthening in low- and middle-income countries (LMICs). The Mental health capacity Building and stRengthening In Global HealTh systems (M-BRIGHT) study seeks to build capacity for delivery of a youth mental health intervention in Vietnam and Cambodia. Objective: This protocol outlines the intervention phase (phase 3) of the study. This cluster-randomised controlled feasibility trial aims to assess the feasibility, acceptability and potential effects of a co-adapted school-based mental health literacy intervention delivered to adolescents in Cambodia and Vietnam. Methods: Seven secondary schools in each country (five intervention, two control) will participate. We aim to recruit ≥175 adolescents in grades 10-11 (aged around 14-18 years at recruitment) per arm in each country (≥700 adolescents overall), along with one parent/guardian per adolescent and ten trained intervention providers per country. The intervention will be delivered over one school year by providers trained in an earlier phase of the study. The intervention combines indoor psychoeducation sessions and peer-led outdoor activities. A mixed methods approach will be used to assess its feasibility, acceptability, fidelity and potential effects. Quantitative measures will be collected through questionnaires at baseline, endline and three months follow-up, including mental health literacy, mental health, wellbeing and parent-reported behaviour. Qualitative interviews and focus groups with adolescents, parents/guardians and intervention providers will explore intervention acceptability. Feasibility criteria include recruitment ≥85%, retention ≥70%, an average of 70% attendance at sessions and ≥70% of sessions delivered as planned. Results: Recruitment took place from September-December (Vietnam) and in November (Cambodia) 2025. Baseline data collection took place in October (Vietnam) and November (Cambodia) 2025; 746 participants were enrolled at baseline across all sites and arms. The intervention will run until May 2026 (Vietnam) and August 2026 (Cambodia), with final follow-up outcome measures expected to be collected by September 2026 (Vietnam) and December 2026 (Cambodia). Conclusions: This study will assess whether a co-adapted, school-based mental health literacy intervention is feasible and acceptable in Cambodia and Vietnam and will explore its potential effects. Findings may inform a future clinical trial and contribute to the evidence base for youth mental health systems strengthening in LMICs.

Background: Childhood mental health conditions remain a major public health concern, particularly in low-resource environments such as rural districts in South Africa. Disorders such as anxiety, depression, Attention-Deficit/Hyperactivity Disorder (ADHD), and autism spectrum disorders are frequently undetected or diagnosed at advanced stages, leading to ineffective management and long-term negative consequences for children’s development and well-being. Objective: This study aims to investigate the factors contributing to the late detection and management of childhood mental health disorders in hospitals within the Umzimvubu Local Municipality, Alfred Nzo District, Eastern Cape Province. Methods: A quantitative, cross-sectional descriptive survey design will be used. All hospitals in Umzimvubu will be included, and a simple random sampling method will be applied manually to select health professionals meeting the study’s inclusion criteria. Online structured questionnaires will be used to collect data. Results: The study protocol has been approved by the University of Venda Higher Degrees Committee and the Research Ethics Committee. Permission from the Eastern Cape Department of Health has been obtained, and site approvals from Alfred Nzo District manager and hospital CEOs are pending. Pretesting and data collection are scheduled to occur in January 2026. Data analysis will be conducted using SPSS version 29. Descriptive statistics and logistic regression will be used to identify factors associated with late detection and management of childhood mental disorders. Results will be presented in tables and graphs. Conclusions: This protocol outlines a study aimed at identifying factors contributing to the late detection and management of childhood mental disorders in hospitals within Umzimvubu Local Municipality. The findings are expected to inform strategies for improving early diagnosis and management, guiding policy development, and strengthening mental health services in rural South Africa.

Background: Post thoracotomy pain remains a major clinical challenge, with substantial impact on pulmonary function, postoperative recovery, and patient quality of life. Thoracic epidural analgesia is widely regarded as the standard of care; however, it is associated with potential complications, including hypotension, urinary retention, and inadequate analgesia in a subset of patients. Intercostal cryoanalgesia, a peripheral nerve block technique that induces temporary axonal degeneration through controlled freezing, has emerged as a potential alternative for prolonged postoperative pain control. Objective: The primary objective of this study is to compare postoperative hospital length of stay between intercostal cryoanalgesia and thoracic epidural analgesia. Secondary objectives include the evaluation of postoperative pain intensity, opioid consumption, adverse effects, postoperative complications, quality of life, quality of recovery, and patient satisfaction. Methods: This is a single-center, prospective, randomized, parallel-group clinical trial comparing intercostal cryoanalgesia with thoracic epidural analgesia for postoperative pain control in patients undergoing thoracic surgery. Fifty adult patients (≥18 years) are randomized 1:1 to either epidural or cryoanalgesia groups. All perioperative and postoperative care is provided by the attending clinical teams according to routine institutional practice, with no influence from the research team beyond randomized allocation. The primary endpoint is postoperative hospital length of stay. Secondary outcomes include pain intensity (visual analogue scale), opioid consumption, incidence of adverse effects and complications, quality of life (WHOQOL-BREF), and quality of recovery (QoR-15). Data are collected up to 1 year postoperatively. Results: Approval from the Human Research Ethics Committee was obtained in November 2024, and participant recruitment began in July 2025. Data collection commenced in September 2026 and is expected to be completed by August 28, 2027. Data analysis will begin in September 2027, with results anticipated in the first quarter of 2028. Conclusions: This study protocol outlines a randomized clinical trial designed to assess clinical outcomes associated with intercostal cryoanalgesia compared with thoracic epidural analgesia following thoracic surgery. The findings are expected to contribute to the evidence base on postoperative pain management and inform the design of future comparative and implementation studies in this field.

Background: As the global population of older adults living with HIV continues to increase, especially in Sub-Saharan Africa (SSA), Canada, the United States, and France, there is a pressing need to comprehend how health systems are addressing the dual challenges of HIV and non-communicable diseases (NCDs) within this demographic. Objective: This scoping review seeks to identify, map, and describe the current evidence regarding tailored and specialized care models for elderly individuals living with both HIV and NCDs in these regions. Methods: Following Arksey and O’Malley’s methodological framework, the research will systematically searches both peer-reviewed on relevant databases such as PubMed, Embase, Web of Science, CINAHL, MEDLINE, Scopus, Global health and other relevant databases and grey literature search on databases such as EMBASE Conference Abstracts, Conference Proceedings Citation Index—Science and Social Science & Humanities to encompass the range of available care model, including Chronic care model, integrated, collaborative service delivery, geriatric HIV models, and multidisciplinary approaches. The selection process will involve two stages: two independent reviewers will initially screen titles for eligibility and a full- text review of the selected articles. A specially designed tool will be used for data extraction, focusing on minimising bias and accurately capturing study details. The final selection of studies will be analysed using a standardised tool to comprehensively assess all bibliographic information and study characteristics. Results: The planned study dates for the review will be August to October 2025. No ethical approval is required as the review will draw on publicly available publications and materials. The study’s conclusions will be subject to peer review and published in a scientific journal, with the abstract shared at local and international conferences. Conclusions: Key findings will be disseminated to health ministries, community- based organisations and policymakers to inform policy decisions regarding implementation of tailored specialised care for elderly population living with both HIV and comorbidity of NCDs.

Background: Fatigue is a common debilitating symptom of breast cancer, and its treatment may result in significant symptom burden and affect adherence to treatment. Graded Exercise Therapy (GET) and Cognitive Behavioral Therapy (CBT) have separately been shown in previous studies to be beneficial for the management of cancer-related fatigue (CRF). Objective: This study aims to assess the feasibility, acceptability and potential efficacy of combining GET and CBT for treatment of fatigue in breast cancer patients on treatment in Singapore. Methods: In this randomized controlled pilot study, a total of 100 female breast cancer patients, with self-reported rating of at least moderate fatigue (One-item fatigue scale score ≥4) will be recruited and randomized in a 1:1 ratio to undergo a combination of GET and CBT versus GET alone (standard of care). This will include a primary cohort of 90 patients with Stage I to III breast cancer who have completed surgery and adjuvant chemotherapy (if indicated), and an exploratory cohort of 10 patients with Stage IV breast cancer undergoing systemic therapy. Acceptability is measured using client satisfaction questionnaire including items on cultural sensitivity. Feasibility is measured by participant uptake, adherence to sessions and willingness to pay for therapy sessions. Efficacy is assessed based on quantitative measures of fatigue, quality of life, and physical and functional outcomes. Results: The recruitment of participants commenced on 14 July 2025 and is projected to be completed by 31 July 2026. Potential extension to this project would be the subsequent expansion of the current exploratory cohort of patients with metastatic breast cancer. Conclusions: The present study compares the use of a combination of GET and CBT against GET alone for management of fatigue in breast cancer survivors, applied to the Singaporean context. The primary aim is to establish feasibility and acceptability of GET and CBT interventions in the local context, with a secondary aim of evaluating efficacy in terms of fatigue, quality of life and functional outcomes.

Background: Existing research on the accuracy of self-assessment (SA) in health professions (HP) has shown poor accuracy of SA compared to external assessors. Objective: We systematically reviewed the evidence for educational interventions aimed at improving the accuracy of SA for technical (procedural) and non-technical (critical thinking, decision making and knowledge) Methods: We conducted this systematic review according to the PRISMA guidelines using Medline, Cochrane Library, Embase, CINAHL, AMED, ERIC, Education Source, Web of Science and Scopus databases. We included studies in English that reported on educational interventions aimed at improving the accuracy of SA versus external assessment across all health professions. A narrative synthesis of the extracted data was used using a convergent integrated approach, which reported both quantitative and qualitative data. We used the modified Medical Education Research Study Quality Instrument (MMERSQI) as the critical appraisal and bias tool to evaluate the methodological quality of included studies. Results: After abstract and full text screening of 7439 studies, we included 35 studies and 3127 participants, the majority of which were of good methodological quality. Twenty-four studies explored SA of non-technical competencies, while 11 studies explored SA of technical competencies. Health professions included medicine (n=16), dentistry (n=9), pharmacy (n=4), nursing (n=2), physiotherapy (n=2), midwifery (n=1) and occupational therapy (n=1). The accuracy of SA was improved with the use of self-assessment rubrics (11 out of 14 studies), video review for feedback (5 out of 12 studies), verbal feedback (2 of 2 studies), electronic portfolios (2 of 2 studies), simulation (2 of 2 studies), and coaching (1 of 1 study). The use of internet-based applications (1 of 1 study) and didactic learning (1 of 1 study) did not improve the accuracy of SA. Conclusions: The accuracy of self-assessment can be improved by using SA rubrics, video and verbal feedback, simulation, electronic portfolios and coaching. Limitations include a clear definition of self-assessment across research studies resulting in exclusion of systematic review. This information can be used by educators to improve the accuracy of SA within health professions education. Clinical Trial: PROSPERO (CRD42024586510)

Background: Clinical natural language processing (NLP) refers to computational methods for extracting, processing, and analyzing unstructured clinical text data, and holds a huge potential to transform healthcare. The advancement of deep learning, augmented by the recent emergence of transformers, has been pivotal to the success of NLP across various domains. This success is largely attributed to the end-to-end training capabilities of deep learning systems. Further, advances in instruction tuning have enabled Large Language Models (LLMs) like OpenAI’s GPT to perform tasks described in natural language. While these advancements have dramatically improved capabilities in processing languages like English, these benefits are not always equally transferable to under-resourced languages. In this regard, this review aims to provide a comprehensive assessment of the state-of-the-art NLP methods for the mainland Scandinavian clinical text, thereby providing an insightful overview of the landscape for clinical NLP within the region. Objective: The study aims to perform a systematic review to comprehensively assess and analyze the state-of-the-art NLP methods for the Scandinavian clinical domain, thereby providing an overview of the landscape for clinical language processing within the Scandinavian languages across Norway, Denmark, and Sweden. Generally, the review aims to provide a practical outline of various modeling options, opportunities, and challenges or limitations, thereby providing a clear overview of existing methodologies and potential avenues for future research and development. Methods: A literature search was conducted in various online databases, including PubMed, ScienceDirect, Google Scholar, ACM Digital Library, and IEEE Xplore between December 2022 and March 2024. The search considers peer-reviewed journal articles, preprints, and conference proceedings. Relevant articles were initially identified by scanning titles, abstracts, and keywords, which served as a preliminary filter in conjunction with inclusion and exclusion criteria, and were further screened through a full-text eligibility assessment. Data was extracted according to predefined categories, established from prior studies and further refined through brainstorming sessions among the authors. Results: The initial search yielded 217 articles. The full-text eligibility assessment was independently carried out by five of the authors and resulted in 118 studies, which were critically analyzed. Any disagreements among the authors were resolved through discussion. Out of the 118 articles, 17.9% (n=21) focus on Norwegian clinical text, 61% (n=72) on Swedish, 13.5% (n=16) on Danish, and 7.6% (n=9) focus on more than one language. Generally, the review identified positive developments across the region despite some observable gaps and disparities between the languages. There are substantial disparities in the level of adoption of transformer-based models. In essential tasks such as de-identification, there is significantly less research activity focusing on Norwegian and Danish compared to Swedish text. Further, the review identified a low level of sharing resources such as data, experimentation code, pre-trained models, and the rate of adaptation and transfer learning in the region. Conclusions: The review presented a comprehensive assessment of the state-of-the-art Clinical NLP in mainland Scandinavian languages and shed light on potential barriers and challenges. The review identified a lack of shared resources, e.g., datasets and pre-trained models, inadequate research infrastructure, and insufficient collaboration as the most significant barriers that require careful consideration in future research endeavors. The review highlights the need for future research in resource development, core NLP tasks, and de-identification. Generally, we foresee that the findings presented will help shape future research directions by shedding some light on areas that require further attention for the rapid advancement of the field in the region

Background: Adolescent anxiety is a growing public health concern and is associated with significant academic, social, and emotional impairment. Mindfulness-based interventions (MBIs) have shown promise in reducing anxiety and improving well-being; however, engagement and acceptability remain challenges. Virtual reality (VR)–based delivery may enhance immersion and attention, potentially addressing barriers associated with traditional mindfulness formats. To date, evidence on VR-based mindfulness interventions for adolescents, particularly in Hong Kong, remains limited. Objective: This study aimed to evaluate the feasibility and acceptability of a virtual reality mindfulness-based intervention (VR-MBI) delivered via a Cave system for adolescents with mild-to-moderate anxiety symptoms in Hong Kong. Secondary aims were to explore preliminary effects on psychological outcomes and physiological stress regulation, and to identify facilitators and barriers influencing engagement. Methods: A mixed-methods single group pre–post study was conducted with adolescents experiencing mild-to-moderate anxiety symptoms, recruited from secondary schools and youth service organizations in Hong Kong. Participants completed an 8-week group-based VR-MBI program. Feasibility and acceptability were assessed using recruitment, attendance, retention, homework practice frequency, dropouts, and adverse events. Psychological outcomes were measured using the Depression Anxiety Stress Scale–21 (DASS-21) and the Mindful Attention Awareness Scale (MAAS). Heart rate variability (HRV) indices (SDNN, RMSSD) were collected at baseline and post-intervention using a wearable device. Post-intervention focus group interviews explored participants’ experiences. Results: A total of 42 participants were enrolled and completed both baseline and post-intervention assessments. Attendance was high, with 73.8% of participants attending at least 80% of sessions, and participants engaged in regular homework practice. No dropouts or adverse events were reported. Quantitative analyses showed no significant pre–post changes in self-reported anxiety, depression, stress, or mindfulness. However, significant improvements were observed in HRV indices, indicating enhanced physiological stress regulation. Qualitative findings suggested perceived benefits in emotional regulation, stress reduction, focus, and sleep, with the immersive CAVE environment and group-based format identified as key facilitators of engagement. Conclusions: The CAVE-based VR-MBI was feasible and acceptable for adolescents with mild to moderate anxiety symptoms in Hong Kong. Although self-reported psychological outcomes did not show significant change, improvements in physiological indicators of stress regulation and positive qualitative feedback suggest early benefits not fully captured by self-report measures. These findings support further investigation of VR-delivered mindfulness interventions using controlled study designs and longer follow-up periods. Clinical Trial: n/a

Background: The CAPABLE (Cancer Patients Better Life Experience) project developed an application for remote monitoring and management of treatment-related symptoms, as well as for delivering a set of supplementary nonpharmacological interventions, with the aim of improving patients’ quality of life. Clinical studies were conducted to evaluate the effectiveness of CAPABLE, yielding encouraging results. However, these studies did not explore individual patients’ perspectives. Objective: Following the evaluation of the CAPABLE intervention’s efficacy, this study aims at exploring end users’ overall experience with the telemonitoring system, identifying strengths and weaknesses in relation to users’ needs and expectations, in order to inform future developments. Methods: Toward the end of the clinical study, a focus group was conducted with a subset of enrolled patients. The discussion was led by a psycho-oncologist using a predefined framework of topic-related questions, which served as prompts to encourage open discussion. Patients freely shared their experiences, and a thematic analysis was performed on the collected statements. Results: The findings showed that the tool primarily served a dual function of support and reassurance. Patients reported psychological relief and a sense of security, driven by the perception of being closely monitored and supported by a multidisciplinary hospital team. CAPABLE was perceived as easy to use, effective, and useful. Nevertheless, several weaknesses also emerged. Suggestions for improvement focused on a closer alignment between CAPABLE functionalities and patients’ individual treatments and preferences, as well as concerns regarding application maintenance after the end of the project. Conclusions: The focus group provided valuable insights to inform the future development of telemonitoring applications for cancer patients.

Background: Knowledge graphs are increasingly important in radiology for representing factual clinical information and supporting downstream applications such as decision support, information retrieval, and structured reporting. However, generating radiology-specific knowledge graphs remains challenging due to the specialized vocabulary used in radiology reports, the scarcity of domain-annotated datasets, and the predominance of unimodal approaches that rely solely on text. Objective: To develop and evaluate a multimodal Vision-Language-Model (VLM) framework capable of generating radiology knowledge graphs using both radiographic images and the corresponding reports. Methods: We designed a VLM-based knowledge graph generation framework that integrates radiology images and free-text reports through instruction tuning and visual instruction tuning. The model is optimized for long-context radiology reports and structured triplet extraction. Its performance was compared with existing unimodal baselines on benchmark datasets. Results: Our multimodal VLM-KG (MIMIC) demonstrated the strongest overall performance across standard NLG metrics, achieving the highest BLEU scores (BLEU-1: 54.98, BLEU-2: 49.65, BLEU-3: 46.12, BLEU-4: 43.29), substantially outperforming all unimodal baselines, including the BERT-based Dygiee++ model. This improvement highlights the effectiveness of multimodal learning, where the integration of visual and linguistic information enhances contextual understanding in text generation. Although Dygiee++ achieved a comparable ROUGE-L score (56.49), VLM-KG (MIMIC) provided markedly higher BLEU scores, indicating stronger n-gram overlap and more accurate triplet generation. VLM-KG (MIMIC) also achieved a competitive ROUGE-L score of 54.69, slightly lower than LLM-KG (MIMIC) (56.53), suggesting that while multimodal features improve precision, they may introduce minor variability in generated outputs. Additionally, LLM-KG (MIMIC) consistently outperformed LLM-KG (IU) across all metrics (e.g., BLEU-3: 35.96 vs. 18.02), underscoring the advantages of training on a large-scale, domain-specific dataset. Conclusions: This study presents the first multimodal VLM-driven approach for radiology knowledge graph generation. By leveraging both images and reports, the framework overcomes limitations of previous text-only systems and provides a more comprehensive foundation for medical knowledge representation and downstream radiology informatics applications.Vision Language Models; Large Language Models; Knowledge Graph; Radiology; Multimodal AI; Medical NLP

Incorporating culturally relevant music can enhance awareness and control in hypertension management and stroke preparedness. The Music4Health initiative created music-driven campaigns focused on youth and their caregivers. We outlined the components of songs developed through community participation to raise awareness about hypertension and stroke preparedness.
The project was conducted in three phases: an open call, a designathon, and a bootcamp. From October 2023 to July 2024, a crowdsourcing open call was launched online and in person. Teams and individuals submitted ideas for creatively disseminating evidence-based prevention strategies for hypertension and stroke through music. Fifteen participants were invited to a 3-day designathon to refine their songs with expert mentors. The final phase, a bootcamp, involved community assessment and intensive workshops with the top six teams to develop and record complete songs with experts and producers. The lyrics from the bootcamp were analyzed using rapid thematic analysis guided by the PEN-3 cultural model, focusing on Relationships and Expectations and Cultural Empowerment domains.
Thematic analysis of the seven finalist songs from the bootcamp identified themes using two PEN-3 model domains. The Relationship and Expectations domains included perceptions of hypertension severity, myths about hypertension (like the role of “juju”), and the necessity for healthy coping strategies. Enablers focused on the availability of hypertension prevention strategies, such as healthy diets, stress management, and avoidance of smoking. Nurturers emphasized raising awareness about hypertension among families, adopting healthy practices for loved ones, and the role of peers in promoting healthy habits. Unique cultural aspects included using Afrobeat and Fuji beats, pidgin English, and references to spirituality in adopting health practices.
Culturally centered music may be an appealing channel for promoting the uptake of evidence-based health interventions. This study highlights the feasibility of using participatory approaches to co-create health dissemination strategies, leveraging music's cultural relevance and appeal to engage youth and their caregivers in hypertension and stroke prevention.

Background: Photoplethysmography (PPG) is widely used in consumer and clinical devices for heart rate, rhythm, sleep, respiratory, and hemodynamic monitoring. However, rapid expansion of applications has produced a fragmented evidence base with heterogeneous methods and variable validation quality. Objective: To synthesize and critically appraise systematic reviews evaluating PPG-based applications in healthcare, map major clinical domains and methodological practices, and identify limitations and priorities for future research. Methods: A protocolized umbrella review (PROSPERO CRD420251015845) was conducted across six databases. Systematic reviews and meta-analyses involving human PPG applications were included. Screening, extraction, and AMSTAR-2 quality assessment were performed in duplicate following PRISMA-S and PRIOR guidelines. Results: Fifty-nine systematic reviews were included. PPG showed consistent accuracy for resting heart-rate monitoring and strong performance for opportunistic atrial fibrillation screening when paired with confirmatory ECG. HRV estimation, stress monitoring, sleep assessment, neonatal and maternal monitoring, and metabolic applications showed emerging but heterogeneous evidence. Cuffless blood pressure estimation remains limited by calibration dependence, motion sensitivity, and poor generalizability. Remote PPG (rPPG) achieves good accuracy under controlled lighting but degrades with motion, light variability, and darker skin pigmentation. Across domains, performance was typically higher in controlled environments and attenuated in free-living settings. Common methodological limitations included small samples, inconsistent reporting of device and preprocessing details, lack of external validation, algorithm opacity, and underrepresentation of diverse populations. Conclusions: PPG is approaching clinical maturity for atrial fibrillation screening and resting heart-rate monitoring, while other applications remain earlier in development. Safe integration into practice requires confirmatory ECG for rhythm abnormalities, awareness of bias sources, and adherence to transparent reporting. Future progress depends on multicenter longitudinal studies, real-world validation, diverse benchmark datasets, standardized metrics, and improved reproducibility across devices and algorithms. PPG holds promise as a scalable component of digital health infrastructure when developed and evaluated with methodological rigor. Clinical Trial: PROSPERO Registration: CRD420251015845

Background: Digital parenting programs offer a scalable solution to improve early childhood development outcomes, especially in low- and middle-income countries like China, but face challenges in sustaining user acceptability and engagement. The culturally specific factors that shape these processes are also not well understood. Objective: This study explored the lived experiences of caregivers and facilitators in a digital-human parenting program delivered within the preschool systems in a lower-middle-income city in China, with a particular focus on the determinants of acceptability, the facilitators and barriers to engagement, and the drivers of perceived changes. Methods: Embedded within a cluster randomized controlled trial in urban China, this qualitative study used semi-structured interviews and focus group discussions with 26 caregivers and 18 program facilitators. Data were analyzed using a thematic approach. Results: Findings demonstrated a virtuous cycle where acceptability (driven by content relevance and digital usability) fostered engagement, leading to perceived changes that reinforced the cycle. Engagement was shaped by intrinsic and extrinsic motivators. Cultural factors were critical: mismatched expectations from the blurred concepts of “parenting” and “education” hindered acceptance, and a "shame culture" inhibited open discussion. An anonymous “Tree-hole” feedback system emerged as a key culturally sensitive solution. Conclusions: The effectiveness of digital parenting interventions in collectivist contexts requires deep cultural adaptation. Interventions must move beyond one-size-fits-all models to incorporate user-centered design and culturally resonant features, such as anonymous feedback systems. A hybrid, family-centered model leveraging trusted human figures is essential for building trust and maximizing impact. Clinical Trial: ChiCTR2400081911

Background: Chronic obstructive pulmonary disease (COPD), emphysema, bronchiectasis, and cor pulmonale are chronic lung diseases (CLD) that pose a global public health challenge. However, there remains a lack of accurate assessment and predictive indicators. The triglyceride-glucose (TyG) index serves as a reliable indicator of insulin resistance (IR). IR is associated with an increased incidence, prevalence, or severity of CLD. Objective: This study aims to investigate the relationship between the TyG index and the risk of CLD, as well as to assess the predictive role of the TyG index in CLD. Methods: Based on data collected from the China Health and Aging Longitudinal Study (CHARLS) from 2011 to 2020, a total of 3,776 research subjects were included for data analysis. K-means clustering analysis was employed to categorize the subjects into three groups. The Kaplan-Meier curve was used to compare the survival rates of CLD events among the groups. Multivariate Cox proportional hazards regression analysis was conducted to examine the relationship between the TyG index and CLD events across the groups. A restricted cubic splines (RCS) regression model was utilized to explore potential linear associations between the TyG index and CLD events. The Receiver Operating Characteristic Curve (ROC) was used to evaluate the predictive value of the TyG index for CLD events. Results: During the follow-up period from 2013 to 2020, 940 subjects were diagnosed with CLD. Based on baseline characteristics, the K-means clustering analysis identified three groups of subjects. The Kaplan-Meier curve indicated statistically significant survival differences among the groups (p=0.0064). After a follow-up period exceeding 50 months, Group 1 exhibited the fastest decline and the lowest rate of disease-free survival. Multivariate Cox proportional hazards analysis revealed that in the unadjusted model, the TyG index of Group 1 was significantly associated with CLD events (HR, 1.58 [95% CI 1.18-2.13], p<0.05). This association remained significant in models adjusted for demographic factors (HR, 1.61 [95% CI 1.18-2.20], p<0.05) and in models adjusted for both demographic factors and disease status (HR, 1.64 [95% CI 1.19-2.26], p<0.05). Similarly, the TyG index in Group 3 showed a significant association with CLD events in both the unadjusted (HR, 1.62 [95% CI 1.12-2.32], p<0.05) and adjusted models (HR, 1.66 [95% CI 1.15-2.39], p<0.05; HR, 1.66 [95% CI 1.14-2.41], p<0.05). RCS curves demonstrated a positive association between the TyG index and CLD events in Groups 1 and 3. ROC curves indicated that the predictive value of the TyG index for CLD events was limited (AUC=0.511-0.548). Conclusions: Research indicates a positive association between the TyG index and CLD in specific populations, although it is not an independent predictor. The calculation and monitoring of the TyG index can aid in risk stratification and the development of intervention strategies for populations.

Background: Mental health conditions (MHC), in particular depression and anxiety are the leading contributors to youth disability globally. In the United States, there has been a steep increase in diagnosed MHC cases over the last decade. Adolescents in rural areas are often disproportionately affected due to a combination of limited access to mental health professionals, and stigma around seeking care. Untreated depression and anxiety can lead to an increased risk of substance use, academic struggles, and delinquency, making early intervention key to preventing such negative outcomes. Current treatment options, mainly psychotherapy and psychopharmacology, have shown modest effects. Prior research suggests associations between slow paced deep breathing and autonomic function, cerebral perfusion, and stress regulation, rendering structured breathing an under-utilized tool for MHC management. Objective: This project addresses two key priorities: reducing health disparities and enhancing population and value-based care in rural communities. This project is grounded in an equity-oriented approach to serving diverse and underserved youth populations by utilizing structured deep breathing, as an accessible and low-cost intervention. Methods: This study assesses the feasibility of collecting functional near-infrared spectroscopy (fNIRS) and data in the full sample and magnetic resonance imaging (MRI) in a subsample of 20 adolescents, without prespecifying neurobiological efficacy hypotheses. We aim to recruit approximately 40 adolescent patients receiving care through the Mayo Clinic Health System (MCHS) from rural communities in northwestern Wisconsin and southeastern Minnesota. All primary and secondary outcomes will be summarized using descriptive statistics, including means, standard deviations, medians, proportions, and 95% confidence intervals, as appropriate. Because this is a pilot feasibility study, the analytic focus is on estimation, variability, and data completeness, rather than hypothesis testing or formal statistical inference. Results: This study focuses on generating feasibility metrics and descriptive summaries of physiological and psychological data to inform future trial design. Conclusions: Adolescents with anxiety and depression are a particularly vulnerable group, often undertreated due to limited access to mental health care. The proposed breathing intervention offers an accessible and scalable tool that integrates multimodal brain physiology measures in rural youth populations.

Background: Artificial intelligence (AI) is rapidly integrating into health professions education (HPE) and clinical practice, creating significant opportunities alongside new ethical challenges. Although current international and professional guidance establishes essential values, it offers limited direction for how clinicians, educators, learners, and institutions should act in routine educational, research, and clinical contexts. The CARE-AI (Contextual, Accountable and Responsible Ethics for AI) project responds to this practice-level gap by articulating guidance that moves beyond values toward professional accountability and equity, with explicit attention to educational and clinical practice contexts. Objective: Our study objective was to develop and validate a consensus-based, actionable framework of principles to guide responsible AI use across health professions education, research, and clinical care. Methods: We conducted a three-phase modified Delphi consensus study, reported in accordance with the Accurate Consensus Reporting Document (ACCORD). Phase I involved two international professional meetings and three purposively sampled focus groups (AI/technology, HPE, ethics/professionalism) to adapt and refine draft principles using an exploratory qualitative approach. Phase II employed an online survey with a 5-point importance scale and prespecified consensus criteria (inclusion ≥70% high ratings; exclusion ≥70% low ratings). Phase III used include/exclude/undecided voting on revised principles. Quantitative thresholds determined consensus. Qualitative free-text comments informed iterative refinement. Results: Participants represented diverse communities of practice across health professions education, clinical care, ethics, and digital health, spanning multiple professional roles and training levels. Across all phases, 303 unique participants contributed to the study. Phase I focus groups (n=61) provided early insight and direction. In Phase II, Delphi survey round 1, 242 participants initiated the survey, with 120 completing it (49.6%). In Phase III, Delphi survey round 2, 103 participants were invited based on expressed interest at the end of Round 1; 78 initiated the survey and 75 completed it (96.2% of starters). In Phase II, 58 of 61 statements (95%) met inclusion, and participants submitted 1,887 comments (697 were content-rich), prompting clearer accountability language, stronger equity commitments, and more usable wording. In Phase III, all nine principles and their statements met inclusion. Participants contributed 224 comments (179 were content-rich) that informed final refinements. Endorsement was near-unanimous: 96% agreed or strongly agreed that the framework clearly defined professionalism expectations for AI to meet educational, technological, and ethical needs in the health professions. Conclusions: The Health CARE-AI Framework, with its preamble and nine principles, articulates actionable, consensus-validated guidance that moves from values to competence, into professional accountability, and toward structural commitments to equity. Paired with a companion implementation guide and toolkit, the framework is intended to support use across education, research, and clinical settings. Clinical Trial: Not applicable

Background: Loneliness is a prevalent and growing concern across the United Kingdom. While numerous validated scales exist to quantify the severity and prevalence of loneliness experiences across populations (the University of California, Los Angeles Loneliness Scale and the DeJong Gierveld Loneliness Scale) (de Jong-Gierveld, 1987; Russell, 1996), there remains a gap in understanding how loneliness manifests and is addressed within therapeutic practice. Given the associated stigma and shame surrounding loneliness self-disclosure, practitioner perspectives offer crucial insights into how clients express loneliness concerns within digital therapeutic environments. Objective: The objectives of this study are to gather the practitioners' perspective of loneliness within a digital therapeutic context, and are defined as follows:
1. To understand how practitioners identify loneliness concerns
2. To identify how loneliness is elicited in digital mental health interventions
3. To identify co-occurring themes (such as grief, shame, and social disconnection) that signal loneliness concerns in client communications within digital therapeutic environments Methods: Semi-structured interviews were conducted with nine experienced practitioners (minimum one year of practice). Participants included specialists in grief counselling, LGBTQ+ support and digital mental health platform therapists. Interview transcripts were analysed using Braun and Clarke's six-phase thematic analysis approach, employing an inductive, data-driven methodology to allow themes to emerge from participant accounts rather than fitting data to pre-existing theoretical frameworks. Results: Four interconnected themes were identified: 1. Conceptualising Loneliness: practitioners distinguished between social contact and meaningful connection, identifying the experience of being “lonely in the crowd” where clients feel disconnected despite having social networks; 2. Contextual Causes: loneliness emerges from life transitions (university, grief, relationships change), stigmatised identities and cultural minorities (LGBTQ+, neurodiversity), and resource reduction (youth services closures and social support); 3. Expressions and Language: specifically that clients rarely expressed loneliness directly, instead using terms like “depressed” or “misunderstood”, with disclosure patterns varying by age and stigma experience; 4. Mental Health Co-occurrence: severe mental health conditions created bidirectional cycles where loneliness exacerbated symptoms, while mental health difficulties increased social isolation. Practitioners reported that 80-90% of their clients experienced loneliness concerns, yet direct disclosure was virtually absent across all participants' experiences. Conclusions: Practitioners identified multiple stigmatising experiences as contextual drivers of loneliness, highlighting how loneliness emerges not only from individual factors but from broader patterns of social exclusion and marginalisation. For therapeutic practice, these insights suggest that practitioners can use awareness of stigmatising experiences as potential indicators when assessing loneliness risk. The presence of these contextual patterns were consistent across digital practitioners’ experiences, providing a foundation to develop more targeted interventions that address both the emotional experience of loneliness and its underlying social drivers across therapeutic environments.

Background: Cerebral Palsy (CP) is the most frequent motor disability in childhood, with a higher prevalence in low- and middle-income countries where access to essential early rehabilitation is limited. Generative Artificial Intelligence (GenAI) emerges as a disruptive technology with potential to address these challenges. This scoping reviews maps the current landscape of GenAI applications in CP rehabilitation. Objective: To systematically review and synthesize literature on the use of GenAI in CP rehabilitation, analyzing its applications, reported benefits, technical/ethical challenges, and future research directions. Methods: A systematic search was conducted following PRISMA 2020 guidelines across five databases (PubMed/MEDLINE, Scopus, Web of Science, IEEE Xplore, Google Scholar) through October 2025. Studies utilizing generative models (LLMs, GANs, VAEs, diffusion models) for diagnosis, assessment, therapy planning, documentation, or education in CP were included. Screening and data extraction were performed independently by two reviewers. Results: From 487 initial records, 32 studies (2022-2025) were included, indicating a nascent field dominated by research in high-income countries. Large Language Models (LLMs) constituted 75% of applications. Four key application categories were identified:
1. Diagnosis/Assessment: LLMs enabled early CP detection from clinical notes (Sensitivity:82%); GANs synthesized movement data to improve GMFCS classification accuracy from 72% to 90%.
2. Therapy Planning: LLMs generated personalized exercise regimens (quality 7.8/10 vs. expert 8.9/10); AI-designed VR content increased therapy adherence by >40%.
3. Clinical Documentation: Automation reduced note-writing time by 55%; AI decision support showed 80% concordance with clinical guidelines.
4. Patient/Caregiver Education: Tailored educational materials significantly improved family knowledge scores.
Reported benefits included enhanced personalization, efficiency, and accessibility. Critical challenges included hallucinations/factual errors, data privacy concerns, algorithmic bias, a lack of interpretability, and risks of dehumanization. Conclusions: GenAI presents significant potential to augment CP rehabilitation by scaling personalization and improving efficiency. However, current evidence is primarily proof-of-concept. Responsible implementation necessitates: (1) robust clinical trials focusing on functional outcomes, (2) development of domain-specific models, (3) ethical frameworks addressing bias and accountability, (4) strategies for equitable global access, and (5) professional training for AI-augmented practice. GenAI should amplify, not replace, the therapist's expertise and the human therapeutic connection. Our collective choices will determine its ultimate impact on care.

Background: Smartphones play a central role in adolescents’ daily lives, making dietary mobile health (mHealth) apps—tools that provide nutrition education and tracking eating behaviors—a promising avenue for influencing dietary habits. While numerous studies have examined the impact of mHealth apps on diet, few have investigated adolescents’ perspectives and experiences with these tools. Objective: This scoping review aimed to synthesize the evidence and map the research gaps on adolescents’ perspectives (positive or negative) and experiences (attitudes, barriers, and facilitators) of using dietary mHealth apps on their smartphones. Methods: A systematic scoping review was conducted according to the 5-stage framework by Arksey and O’Malley. Articles that included mixed-methods studies that focused on adolescents (10-19 years of age) reporting perspectives (positive or negative) and experiences (attitudes, barriers, and facilitators) related to dietary apps use were searched across: PsycINFO, Embase, Medline, Web of Science and CINAHL for studies that were published from 2012 until 2023. Articles that were not specific to diet, not research studies, and not written in English were omitted. Results: Of the 590 abstracts screened, 17 studies met the eligibility criteria. Ten studies assessed the usability, feasibility and acceptability of standalone or multi-component dietary mHealth apps, while nine examined app likability and effectiveness. Thematic analysis revealed seven overarching themes: (1) Technical Functionality and Usability; (2) Appreciation of Nutritional Education and Content Depth; 3) Importance of Social Connection, Feedback and Support; (4) Values of Entertainment and Gamification; (5) Significance of Personal Goals, Motivation and Tracking; (6) Interest for Simple Design and Interface; and (7) Perceived Effectiveness of Dietary mHealth Apps. Positively perceived features included food identification, tracking and gamification elements. Commonly barriers included technical difficulties, tracking inaccuracies, complex information delivery and limited social engagement. Facilitators to app use were ease of navigation, targeted information, social interaction, rewards and goal setting. Suggested improvements focused on tracking accuracy, interface design, feedback mechanisms and notification options. Overall, adolescents perceived effective apps to as those that raised awareness of eating habits and support improvements in dietary intake. Conclusions: This scoping review highlights that adolescents’ experiences with dietary mHealth apps are shaped by technical functionality, usability, social engagement, personalization, and gamification. While these features can enhance engagement, barriers such as tracking inaccuracies, technical issues, and limited social interaction reduce app effectiveness. Understanding these perspectives is critical for designing apps that are not only informative but also appealing and sustainable for adolescent users.

Background: Abstract
Digital transformation in healthcare, including electronic health records, telemedicine, data analytics, and mobile health applications, is reshaping service delivery and patient experience. However, evidence on how these technologies influence e-healthcare service quality within developing countries remains limited. This study aimed to examine the impact of digital transformation on e-healthcare service quality through the mediating role of clinical process change. A quantitative, cross-sectional survey design was conducted among healthcare users in Alexandria Egypt private sector data. Data were collected using validated instruments addressing electronic health services, telemedicine, data analytics, and mobile applications, with physician–patient communication. Responses were analyzed to assess perceptions of accessibility, security, usability, and service quality. Findings showed a predominance of neutral attitudes toward digital health technologies. Nearly half of respondents (45%) were neutral about accessibility, and only 32% strongly agreed that records were secure. Neutrality was also common regarding data analytics (33.8% awareness, 38.0% quality of care, 32.8% decision-making) and mobile applications (36.8% user-friendliness, 34.3% wait time reduction, 38.5% technical reliability). Communication indicators showed moderate ratings, with neutrality prevailing for physician listening (34.0%) and patient comfort (32.3%). Despite neutrality, around one-third agreed on the convenience of telemedicine and clarity of information provided (45.8%). The study demonstrates that digital transformation, mediated partly through clinical process change, enhances clinical workflows and perceived e-healthcare service quality. However, widespread neutrality indicates knowledge gaps, highlighting the need for user-centered design, digital literacy training, and improved communication to maximize the benefits of healthcare digitalization.
Keywords: Digital transformation; E-healthcare service quality; Clinical process change; Data analytics; Telemedicine. Objective: The study aims to achieve the following objectives:
1. To examine the scope and evolution of digital transformation in healthcare systems.
2. To identify the key enablers of successful digital transformation, including technological infrastructure and leadership.
3. To explore the major barriers to digital health implementation.
4. To assess the impact of DT on healthcare delivery, patient outcomes, and provider experience.
5. To develop a conceptual framework to guide future digital transformation efforts. Methods: 6.1 Research Design
A quantitative, cross-sectional survey design was employed to examine the relationships between digital transformation (DT), clinical process change (CPC), and healthcare e-service quality in private hospitals in Egypt. Structural Equation Modeling (SEM) using Partial Least Squares (PLS-SEM) was used to test the hypothesised mediation model.
________________________________________
6.2 Target Population and Sampling Frame
The target population consisted of patients who received services from private hospitals in Egypt during the data collection period. Staff members or clinical professionals were not included in the sample to maintain conceptual consistency, because the dependent variable—e-service quality—is evaluated by patients, not employees.
The sampling frame covered adult patients (≥18 years old) who visited outpatient departments, emergency units, or utilised digital channels (e.g., mobile apps, portals) during the study period.
________________________________________
6.3 Sampling Strategy and Justification
A convenience sampling approach was used due to practical constraints, including variable patient flow across hospitals and restricted access to patient records. Although probability sampling is ideal, convenience sampling is widely acceptable in healthcare service quality research when direct access to sampling lists is not feasible.
To mitigate limitations, recruitment occurred across multiple hospitals, different days of the week, and various service units to improve representativeness. Results: 7. Results
This study presented and analyzed the empirical findings of the study investigating the impact of Digital Transformation through the dimensions of E-health Records, Telemedicine Services, Data Analytics, and Mobile Applications on E-healthcare Service Quality within Egypt’s private healthcare sector, with Clinical Process Change acting as a mediating variable.
The descriptive analysis offered a clear understanding of the respondent demographics, suggesting a sample of digitally literate and experienced users.
The results revealed generally positive attitudes toward digital healthcare services, especially in areas related to telemedicine convenience, mobile app functionality, and perceived security.
Using Structural Equation Modelling (SEM), the study validated a strong model fit and confirmed the reliability and validity of the measurement constructs. The analysis demonstrated that Digital Transformation has a significant positive impact on both Clinical Process Change and E-healthcare Service Quality.
Furthermore, the results established that Clinical Process Change partially mediates the relationship between Digital Transformation and E-healthcare Service Quality (H4), reinforcing the importance of internal operational improvements in realizing the benefits of digital initiatives.
Overall, the findings confirm that successful digital transformation initiatives in healthcare not only require technological implementation but must be accompanied by clinical process enhancements to achieve higher service quality. These results have significant implications for healthcare decision-makers, emphasizing the need to invest in integrated digital and process change strategies to improve patient outcomes and service delivery in the digital age.
Figure 4 shows the measurement model which consists of 11 latent variables, namely, E-health records, Telemedicine services, Data analytics, Mobile App, Physician-Patient Interaction, Information Accessibility, Security, Responsiveness, Reliability, Ease of use and Loyalty. Conclusions: Conclusion
Our empirical results resonate strongly with the broader scholarly literature: digital transformation including E health records, telemedicine, data analytics, and mobile apps significantly enhances both clinical processes and perceived e healthcare service quality. The partial mediation through clinical process change further corroborates system-level frameworks and empirical studies describing how digital tools translate into quality improvements when embedded in improved clinical workflows. These results provide solid academic validation and practical guidance for implementing digital innovation in healthcare.

Background: Pediatric survivors of critical illness often face persistent psychosocial challenges after PICU (Pediatric Intensive Care Unit) discharge, but follow-up support across hospital, home, community, and school settings remains inconsistent. Digital interventions could help bridge these gaps and support recovery. Objective: To systematically review the literature on digital psychosocial follow-up solutions for children who survived critical illness, describing target populations, intervention design, evaluation methods, and psychosocial effects. Methods: A systematic literature review was performed using the Scopus database, supplemented by backward citation searches and hand searches of related reviews. Eligible studies included children surviving medical conditions potentially requiring PICU care, implemented a digital intervention (excluding telephone-only), and evaluated psychological or social outcomes; studies published before 2010, in non-English languages, not peer-reviewed, lacking full text, not original research, involving mixed child-adult populations, or with unspecified participant age or diagnosis were excluded. The quality of the included studies was appraised with the MMAT (Mixed Methods Appraisal Tool) 2018. Owing to heterogeneity in populations, interventions, comparisons, outcomes, and study designs, a narrative synthesis was applied. Results: Thirty-three publications reporting on 31 unique studies (N=1,717 participants, ages 0–17) were included. The studies spanned North America, Europe, and Asia and were conducted in inpatient, outpatient, home, and school contexts. Interventions comprised web applications (n=9/31), mobile apps (n=7/31), social robots (n=6/31), video games (n=4/31), and mixed modalities (n=5/31). Many studies (n=18/31) engaged guardians as co-participants or co-developers along with children. Target conditions were predominantly cancer (n=11/31), type 1 diabetes (n=8/31), and asthma (n=7/31). Mixed methods designs were most common (n=11/31), followed by nonrandomized quantitative trials (n=7/31) and randomized controlled trials (n=6/31). Most studies reported positive psychosocial effects. Across outcomes, self-management (n=3/31) and quality of life (n=5/31) showed the most statistically significant (P<.05) benefits. Evidence for psychosocial outcomes was less consistent. The certainty of evidence was limited by a single-database search, single-reviewer screening, variable methodological quality, and heterogeneity. Conclusions: Digital psychosocial follow-up for childhood critical illness survivors appears feasible and promising, particularly for self-management and quality of life, but the evidence base is heterogeneous and methodologically constrained. To strengthen clinical translation, future work should prioritize rigorous trials, standardized and theory-informed pediatric psychosocial outcome sets, longer follow-up, transparent reporting, and equity-focused designs that integrate family-centered hybrid clinic-home pathways and, where feasible, predictive features.

Background: The Ready-Made Garments (RMG) industry is a vital part of Bangladesh's economy and employing over 4 million workers from low-income backgrounds that generally neglects their healthcare aspects. Historically, the sector is criticized for labor exploitation, unsafe working conditions, and rights violations since there has been massive loss of lives over accidents. While compliant factories adhere to better labor standards, many non-compliant factories expose workers to poor conditions, increasing their health risks. The COVID-19 pandemic exacerbated vulnerabilities within this workforce, resulting in widespread factory closures and massive job losses, heightened health risks, and leaving millions of workers without wages. Although the government provided some relief, it lacked policies for job security, social protection, health services, and emergency relief. Although technology has played a critical role in crisis response and healthcare, access to these technologies remains limited for them due to digital literacy gaps. Many RMG workers primarily use basic mobile phones for communication, not for accessing health or emergency services. Therefore, there is a need to develop a sustainable system that leverages their existing technological familiarity to ensure their voices are heard. Objective: Our aim was to gain a deeper understanding of RMG workers' experiences based on their existing work environments and interactions with technology, healthcare management, and the impact of COVID-19 on their circumstances. By understanding these aspects, we can recommend a technology-based framework design that serves as a sustainable and contextual model. Methods: We conducted in-person interviews with 55 RMG workers, comprising 32 female and 23 male participants from urban and suburban areas of Dhaka and suburban Gazipur, in Phase 1, before the pandemic. The participants were aged between 18-40. We reconnected with 12 participants from Phase 1 during the pandemic in Phase 2, in addition to three stakeholders from RMG factories via one-on-one phone conversations. Each interview was conducted in Bengali, and we obtained consent to record the audio. Overall, 846 minutes of discussion were translated and transcribed. The results were analyzed using thematic analysis. Results: We found insights into the working conditions, personal experiences, perceptions of healthcare, lifestyle choices, and technology use, all of which differed based on the type of factory which is yet not discussed together. Those employed at compliant factories enjoyed better healthcare support and utilized technology more effectively compared to their counterparts in non-compliant factories. Due to the pandemic, the situation for all workers changed dramatically, regardless of factory compliance, leading to major impacts on their daily lives, heightened health and safety worries, and a lack of emergency assistance. The RMG sector encountered a lot of challenges, underscoring the pressing need for targeted emergency relief and healthcare services for these workers. Conclusions: This research examined the workplace and daily lives of RMG workers, focusing on their challenges, healthcare perspectives, and technology use during the pandemic. Based on the findings, we proposed a technology-based framework design called VOICE, which connects workers to service providers through a straightforward interface. This would help reach marginalized communities during emergencies and provide essential support to improve their well-being.

Background: The fragmentation of electronic health records (EHRs) is a major barrier to integrated cancer care, negatively impacting diagnostic efficiency and treatment continuity. Blockchain technology has emerged as a promising solution for secure health data sharing, with the potential to enhance interoperability, data governance, and traceability in complex clinical settings like oncology. However, the successful implementation of such technology is contingent upon patient acceptance and trust, which remain underexplored. Objective: This study aimed to investigate the perceptions of oncology patients regarding the use and control of their digital health data. We specifically assessed their willingness to share information, their level of trust in different stakeholders within the healthcare ecosystem, and the conditions under which they would find blockchain-based solutions acceptable. Methods: We conducted a cross-sectional, exploratory, quantitative study with 110 oncology patients at Hospital Santa Izabel in Salvador, Brazil. A structured questionnaire, validated by experts for clarity and relevance, was used. Data collection was managed via the REDCap platform. The instrument's internal consistency was assessed using the Cronbach's alpha coefficient. Descriptive, comparative, and correlational statistical analyses were performed to identify differences across sociodemographic groups. Results: A majority of participants demonstrated a high acceptance of digital tools for storing and sharing health data (86.4%), which increased significantly when security measures like anonymization and encryption were assured (83.6%). Trust in data sharing varied substantially by institution: it was highest for healthcare professionals (79.1%), moderate for hospitals (51.8%), and considerably lower for the government (10%) and the pharmaceutical industry (15.5%). A statistically significant difference was found in technology adherence by age, with younger patients (18-59 years) showing higher acceptance than older adults (p = 0.024). The survey domains—self-management, adherence, and governance—demonstrated satisfactory internal consistency (Cronbach's alpha ranging from 0.75 to 0.88). Conclusions: Our findings indicate a high willingness among oncology patients to adopt digital health tools for data management, provided that robust security, transparency, and patient empowerment are central to the design. The significant trust gap between clinicians and institutions like government and industry underscores the critical need for clear communication and trustworthy governance models. To foster confidence and promote equitable access, future digital health platforms must be designed to be accessible, reliable, and centered on patient autonomy. Clinical Trial: This was an observational, cross-sectional study and did not involve a clinical intervention. Therefore, registration in a clinical trials registry (such as ClinicalTrials.gov) was not applicable. The study was conducted with the approval of the Institutional Review Board (CAAE: 70726523.3.0000.5520). All study records, including de-identified raw data, the survey instrument, and consent forms, are securely archived by the authors in accordance with institutional and ethical guidelines.

Background: The COVID-19 pandemic gave rise to a global “infodemic” in which social media platforms amplified misinformation. Despite high social media adoption rates and heavy reliance on social media for pandemic news in Arab-speaking countries, relatively little is known about the prevalence and characteristics of online Arabic COVID-19 misinformation. Objective: To capture and analyze a snapshot of the COVID-19 misinformation ecosystem in Arabic, identifying characteristics and patterns to guide future research and interventions of particular benefit to this linguistic region. Methods: We compiled a database of 234 COVID-19 misinformation claims published online from March 2020 to March 2022, sourced from four International Fact-Checking Network (IFCN)-certified Arabic fact-checking organizations. Claims were coded inductively and deductively with high inter-rater reliability, to determine misinformation type (κ = 0.88), narrative typology (κ = 0.913), framing strategies (κ = 0.72), medical jargon usage (κ = 0.794), and societal implications (κ = 0.752). All Cohen's kappa coefficients were significant at p < 0.001. Results: Facebook was the most popular platform, followed by Twitter, with regular users being the primary source of debunked claims. The most prevalent narrative typologies were COVID-19 biological aspects (origins, existence, diagnosis, prevention, transmission, and cures) (47.2%) and vaccines (30%). Fabricated/manipulated (54.9%), followed by misleading content (36.9%), were the most common misinformation types. The most frequent framing strategy involved distortion of science and medicine (29.6%), followed by entertainment/satire (23.6%), political content (18.9%), and conspiracies (13.3%). Notably, 36.3% of claims were translated from English, and only 50% of the analyzed content was moderated by the original platforms. Conclusions: Fact-checked Arabic COVID-19 misinformation exhibited distinct patterns, including heavy reliance on translated content, manipulated content, and scientific distortion as a credibility strategy, and significant gaps in platform moderation. These findings highlight the need for enhanced Arabic-language content moderation, cross-linguistic fact-checking collaboration, culturally appropriate media and health literacy interventions, and rebuilding institutional trust to address misinformation in the Arab-world effectively.

Background: Amidst the COVID-19 pandemic, Action4Diabetes (A4D), a non-profit organisation collaborating with local healthcare professionals across Southeast Asia (SEA), developed HelloType1 a digital educational platform for Type 1 diabetes (T1D) in regional languages. Launched sequentially in Cambodia (2021), Vietnam (2022), Thailand (2022), and Malaysia (2023) through Memorandums of Understanding (MOUs), the digital platform aimed to improve diabetes awareness, education, and access to credible local-language resources. Objective: This study aims to evaluate the usability, reach and online engagement of HelloType1 from 2021 to 2024. Methods: Website traffic data from Google Analytics (GA4) and Facebook metrics were analysed to assess user growth, traffic sources, and engagement trends across countries. Results: Total users increased by 645% between 2021 and 2022 and a further 31% between 2022 and 2023. By 2024, 78% of visits originated from search engines, 13% from social media, and 9% from direct access. Pageviews rose from 4,644 (2021) to 82,689 (2024). Facebook followers grew from 940 to 4,553, with engagement rates increasing from 8% (2022) to 29% (2024). Cambodia achieved the highest reach, while Vietnam showed strong engagement among younger female caregivers. Conclusions: HelloType1 demonstrates a scalable, low-cost digital model for delivering culturally adapted T1D education in resource-limited SEA settings. Clinical Trial: NA

Background
Cancer predisposition syndromes (CPS) are identified in approximately 10% of pediatric cancer patients, with an increasing number of affected families each year. Despite the known psychosocial challenges faced by these families, including uncertainty in communication, genetic risk implications, and lifelong surveillance, there is limited data on the specific support needs of families in Germany.

The KiTDS-Care study aims to: (1) Conduct a comprehensive analysis of the current care landscape, psychosocial stressors, psychosocial burden and support needs of families with children/ adolescents diagnosed with CPS in Germany; and (2) Develop recommendations for improving psychosocial care based on these findings.
Methods
A mixed-methods approach will be employed. The first phase involves a systematic review to systematically gather existing literature on the psychosocial situation and support needs of CPS families. In the second phase, a cross-sectional survey of families (parents and children/ adolescents aged ≥7 years) will assess e.g. psychosocial well-being, quality of life, support needs, and care utilization. Additionally, qualitative interviews will be conducted with families and healthcare providers to explore deeper psychosocial experiences, service and care gaps. Data will be analyzed using descriptive and inferential statistics, while qualitative data will be processed through content analysis. Recommendations for psychosocial care will be derived and validated through feedback from both families and healthcare professionals.
Discussion
The study results will provide a comprehensive overview of the psychosocial situation and supportive care needs of families affected by CPS of a child/ adolescent. The results will help to improve family-centered care and psychosocial support systems. It will help identify gaps in current care practices and inform more effective approaches.

Background: Due to demographic change the number of older people is increasing. Older age is often accompanied by limitations in terms of mobility, nutrition and independence. Routine, preventive monitoring of these areas is rare, as care systems struggle with staff shortages and limited resources. Technical assistance systems offer a way to support older people (≥70 years) in self-assessing their health parameters and in consequence keep independence. We developed the AS-Tra system which combines an app with a measurement and training station (MuTS) to identify deficits and risks in the areas of nutrition and mobility in older adults at an early stage. Objective: This paper presents the pilot study of the AS-Tra system with the aim of evaluating its usability and testing the feasibility of collecting health-related data of older adults (70+) with early / mild deficiencies in nutritional state and physical functionality in preparation for a future randomized controlled trial (RCT). Methods: The system was developed as a complex intervention in accordance with the Medical Research Council (MRC) framework. In this pilot study, the participants used the system four weeks. The assessments (grip strength, Timed ‘Up and Go’, 5-Time Chair Rise) were conducted at the baseline (BL) as well as after one, two and four weeks (T0, T1, T2). At BL, inclusion criteria, baseline characteristics, MNA-SF and SPPB were recorded. Participants received a tablet containing the app and an activity sensor to measure physical activity for seven days. At T0, next to the assessments, the training exercises were introduced and carried out. At T1 the assessments were repeated, along with registering a 3-day food diary in the tablet app and the activity sensor data was evaluated. At T2, the final assessments, including MNA-SF, SPPB, SUS, and feedback questionnaires as well as the ‘Evaluation Overall System’-questionnaire (EOS) (evaluation of all subcomponents on a scale of 1 to 5) were collected. Throughout the entire period of use, participants were asked to train independently in MuTS at least once a week. They regularly kept a food diary using the tablet app and were asked to provide feedback on the app and MuTS in form of an ‘Experience Report’-questionnaire (ER), in which it is asked which elements caused problems and which were particularly easy. Results: Ten participants (80 ± 5 years, 50% female) participated in this study, of which one droped-out between T0 and T1. The SUS score was good (79 ± 13.4). The MuTS devices had minor technical problems (in <17% of the usage) according to the ER, while 57% of the users experienced instability issues with the food diary in the tablet app. Overall, ratings of the system were very good with good with slightly lower ratings (2–3 out of 5) for the tablet app and regular use. Conclusions: The usability of the technical assistance system used in this study was rated as good. The data collection with questionnaires, sensors, and automated assessments proved feasible. The biggest challenge was the tablet-based food diary which still needs improvement, before the effectiveness of the AS-Tra system regarding mobility and nutritional status will be evaluated in a RCT.

Background: Continuing Medical Education (CME) is a legal and ethical obligation for physicians in Germany. The rapid rise of large language models (LLMs) such as ChatGPT, Gemini, Claude, and Grok raises concerns about the integrity of CME assessments, as LLMs can already pass German CME tests. Objective: To determine whether the choice of document format (searchable PDF, raster PDF, vector PDF) and LLM can influence the solvability of CME test questions by LLMs above the passing threshold specified for each CME module (typically 70%). Methods: In a fully crossed within-subjects repeated-measures structure, 18 expired CME articles from three major German publishers across six specialties will be converted into three PDF formats and processed by four current LLMs (ChatGPT-5, Mistral 3.1 small, Claude Sonnet 4, Grok-4) and two predecessor versions (ChatGPT-4o and Grok-3). Each model will answer every article once per file-format condition. This results in 18 experimental conditions. The primary outcome is the proportion of correctly answered questions; secondary outcomes are pass/fail rate and efficiency. The study has been approved by the University of Witten/Herdecke Ethics Committee (reference number S-260/2025, dated 08.10.2025) and is preregistered at the Open Science Framework (DOI: 10.17605/OSF.IO/V96R5). Results: Data collection will start in January 2026 and will last approximately 4 weeks. As of December 2025, the study has been preregistered, and no results are available yet. The analyses will quantify performance differences across document formats and model generations; these findings may inform the feasibility of non-searchable document formats as a temporary measure to reduce AI-enabled cheating risks in CME contexts. Conclusions: By quantifying how document format constrains LLM performance, this study aims to evaluate simple technical safeguards that may reduce AI-assisted manipulation of CME tests and inform regulators and CME providers on balancing assessment validity, accessibility, and responsible LLM integration into postgraduate medical education.

Background: Atopic dermatitis (AD) affects 10–20% of children and 5–10% of adults, with approximately 89% of cases being diagnosed as mild to moderate. AD influences over 200 million individuals around the world and is viewed as an important health problem due to its elevated prevalence, long course of disease, and heavy disease burden. Qi Wei Antipruritic Lotion is an empirical prescription formula composed of eight Chinese herbs, with purported effects of clearing heat, drying dampness, detoxification, and alleviating pruritus. While it is employed in clinical settings for pruritic dermatoses, robust evidence from high-quality clinical trials is still lacking. This study will evaluate the efficacy and safety of QW Antipruritic Lotion for the treatment of AD. Objective: This study will evaluate the efficacy and safety of QW Antipruritic Lotion for the treatment of AD. Methods: Methods and analysis: This single-center, randomized, double-blind, placebo-controlled trial will enroll 154 patients with mild-to-moderate AD from the Hospital of Chengdu University of TCM. Participants will be randomly assigned (1:1) to either the treatment group (QW Antipruritic Lotion) or the placebo control group. The trial comprises an 8-week treatment period followed by a 12-week follow-up. Efficacy will be assessed using several endpoints to measure Improvement in clinical severity. The primary outcome is the reduction in the SCORAD (Scoring Atopic Dermatitis) index. Secondary outcomes include the Eczema Area and Severity Index (EASI) scores, the Patient Self-Assessment Questionnaire (DQLI, NRS), as well as safety outcomes. A clinical dermatologist will perform assessments at baseline (week 0), weeks 4, 8, 12, 16, and 20. Results: This study will evaluate the efficacy and safety of QW Antipruritic Lotion for the treatment of AD. Conclusions: This study will evaluate the efficacy and safety of QW Antipruritic Lotion for the treatment of AD.

Background: In a significant proportion of carotid interventions, carotid graft replacement is required to achieve a successful outcome both as primary method or as bail-out solution. An exhaustive mapping of the sparse and heterogeneous evidence available in the literature may provide a more comprehensive understanding of this topic. Objective: This scoping review aims to examine and summarize the evidence from scientific literature concerning the role of graft interposition during elective and emergent carotid interventions. Methods: This scoping review will be conducted following recommendations outlined by Levac et al and will adhere to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews) guidelines for reporting. Peer-reviewed papers written in English will be searched in the following databases: PubMed/MEDLINE, Embase, Scopus, and Web of Science. The web-based systematic review platform Rayyan will be used to create a data extraction template. It will cover the following items: elective carotid endarterectomy, emergent carotid endarterectomy, carotid artery restenosis, carotid artery trauma, carotid artery aneurysm, carotid artery dissection, carotid patch infection, internal carotid artery fibrosis, carotid artery tumour. All study designs (RCTs, observational, case series) will be considered. Non-English studies, animal studies, cadaveric/anatomical-only reports, purely technical notes without clinical data. An data regarding extracranial-to-intracranial bypass will be excluded. Study selection based on title and abstract screening (first stage), full-text review (second stage), and data extraction (third stage) will be performed by a group of researchers, whereby each paper will be reviewed by at least 2 people. Any conflict regarding the inclusion or exclusion of a study and the data extraction will be resolved by discussion between the researchers who evaluated the papers; a third researcher will be involved if consensus is not reached. Results: A preliminary search of PubMed/MEDLINE, Embase, Scopus, and Web of Science was conducted, and no current or ongoing systematic reviews or scoping reviews on the topic were identified. The results of the study are expected in July 2026 Conclusions: Our scoping review will seek to provide an overview of the available evidence and identify research gaps regarding the role of graft interposition during elective and emergent carotid interventions.

Background: Obesity remains a pressing global health issue. Research suggests that better health literacy can support obesity management. This study tested digital interventions combining healthy eating guidelines with AI and mobile tools, including a ChatGPT-powered Line chatbot for daily education and an AI food plate recognition system for calorie tracking and meal suggestions. Objective: This study aims to evaluate the efficacy of an integrated digital intervention, combining YOLOv5-based AI food plate recognition and a ChatGPT-powered LINE chatbot, on weight reduction (BMI) and health literacy among overweight and obese adults. Methods: The study used a quasi-experimental design-intervention case-control design. Both the case and intervention groups received basic health education through app notifications and used an AI food plate recognition tool to estimate their nutritional intake. Only the intervention group could access an AI weight-loss chatbot for timely suggestions. Questionnaire data were collected from users at several points during the intervention. Results: Eighty participants were enrolled. The intervention group demonstrated significantly greater reductions in BMI (β = −1.32; 95% CI, −1.56 to −1.09; P < .001) and improvements in health literacy (β = 4.71; 95% CI, 3.86 to 5.56; P < .001) versus controls. Physical activity (step count β = 1,926.5; 95% CI, 1,209.3 to 2,643.7; P < .001) and weekly exercise time (β = 0.56; 95% CI, 0.21 to 0.92; P = .002) also increased, while late-night snacking decreased (β = −0.45; 95% CI, −0.81 to −0.08; P = .017). The intervention group consistently outperformed the control group across key health measures. However, the AI chatbot alone lacked significant effects on primary outcomes. Conclusions: This integrated digital intervention effectively promotes weight loss and health literacy. Given the strong short-term efficacy, future research should employ randomized designs, larger sample sizes, and longer follow-ups to establish long-term weight maintenance and address potential influences such as the Hawthorne effect. It also highlights the need to further develop interactive, personalized health education tools and optimize AI food plate recognition systems to improve health literacy and weight management.

Background: In Bangladesh, infertility is an increasing concern, influenced by cultural, social, and economic factors. One of the leading contributors to female infertility is Polycystic Ovarian Syndrome (PCOS), a common endocrine disorder that affects women of reproductive age. Characterized by elevated androgen levels, PCOS results in the development of multiple fluid-filled cysts on the ovaries, disrupting normal ovulation. The current fertility rate in Bangladesh stands at 1.93 births per woman as of 2023, reflecting a decline in recent years. Objective: This study aimed to identify risk factors associated with infertility in women and to explore potential prevention and treatment strategies. Methods: Conducted as a cross-sectional study at two tertiary hospitals, 189 women participated, with 163 diagnosed with PCOS and facing prolonged difficulties in conceiving. The data were analyzed using SPSS software, employing descriptive statistics, comparative analysis, and multivariate logistic regression. Results: The results showed that the average age of the participants was 26.96 ± 4.88 years, with an average infertility duration of 5.03 ± 2.80 years. The highest prevalence of PCOS was observed in women aged 19-25 (40.2%), followed by those aged 26-30 (31.8%) and 31-35 (15.1%). A smaller percentage (3.9%) were aged 36-40. The findings indicate that most PCOS-related infertility cases occur in women in their early 20s. Conclusions: Despite its prevalence, PCOS poses significant health risks, including type 2 diabetes and hypertension. Effective management of PCOS is essential for reducing its long-term health impacts and improving reproductive outcomes for women in Bangladesh.

Background: Autism Spectrum Disorder (ASD) is characterized by persistent difficulties in social communication, restricted interests, and sensory challenges. Although Applied Behavior Analysis (ABA) is widely used, traditional interventions often face challenges, such as high costs, limited access to qualified therapists, and balancing structured therapy with individual needs. Recent advances in consumer-grade virtual reality (VR) and artificial intelligence (AI) offer opportunities to design personalized, immersive interventions aligned with naturalistic developmental behavioral intervention (NDBI) principles. Objective: This study aimed to design, develop, and evaluate an immersive VR game, the “Elevator Game” for verbal requesting and social initiation, to determine its feasibility, acceptability, and preliminary behavioral impact on children with ASD. Methods: Three children with autism and limited verbal skills participated in home-based VR sessions consisting of 10-15 minutes of gameplay followed by breaks. Results: Results suggest the intervention is feasible, well tolerated, and associated with increased spontaneous verbal requesting. Conclusions: AI-assisted VR interventions integrating ABA and NDBI principles are feasible, engaging, and potentially effective for children with ASD, including those with limited progress in traditional therapy. Personalized reinforcers, immersive engagement, and sensory-adaptive environments appear critical for success. Findings support further development and evaluation in larger trials.

Background: The growth of patient-facing health technology has the potential to transform the delivery and receipt of patient-centered primary care. However, successful integration of data from these digital tools into clinical workflows depends not only on technical efficacy, but also on usability across diverse patient populations. To ensure the successful integration of digital tools, Tech Testing Panels (TTPs) can assess usability and provide feedback. Objective: This study aimed to assess technology usage and literacy among adult primary care patients that opted in a TTP and compare these measures between English-preferred and Chinese-preferred speaking patients. Methods: We conducted a cross-sectional online survey from April to July 2024 at an urban academic primary care based TTP composed of adult patients that use the patient portal and spoke English and/or Chinese. The survey assessed socio-demographic characteristics and technology usage and literacy, including comfort with app installation, video chat setup, and problem-solving tech issues. Respondents received a $5 online gift card for completion. Bivariate analyses were conducted using Pearson’s chi-squared and Fisher’s exact tests to compare responses by preferred language. Results: Of the surveys distributed, the response rate for surveys in English was 53.7%, while the response rate for surveys in Chinese was approximately 27.0% with a total sample size of 222 respondents. Respondents had a mean age of 61.6 years, with nearly half aged 65 or older. A majority had high educational attainment and household incomes. Most respondents strongly agreed that they could install applications (85.5%) and able to initiate video chats independently (82.4%). Internet access was nearly universal (99.1%), and patient portal usage was high (99.1%) with most accessing the portal via smartphones or tablets (54.8%). However, Chinese-preferring respondents reported significantly lower technology literacy across multiple domains compared to English-preferring respondents, including lower confidence in using applications (64.5% vs 89.0%, P=.001) and resolving technical issues (38.7% vs 60.0%, P<.001). Conclusions: While technology usage was high in this sample of adult primary care patients in a TTP, disparities by preferred language in technology literacy persist. Chinese-preferring patients were less confident in navigating digital tools, despite similar technology usage. These findings underscore the importance of TTPs with diversity in technology literacy to support inclusive development of culturally and linguistically responsive patient-facing digital tools. Addressing barriers identified among end users with different degrees of technology literacy will be essential to ensuring equitable adoption of digital health tools and supporting inclusive innovation in primary care.

Background: Large language models (LLMs) are increasingly used and evaluated in health professions education, including studies assessing model performance on healthcare examination questions. The rapid growth and heterogeneity of this literature make it difficult to track research concentration, collaboration patterns, and emerging themes. Objective: To map publication trends, key contributors, collaboration networks, and thematic hotspots in research on LLM-supported exam solving in healthcare education. Methods: We conducted a bibliometric analysis of publications from 2023–2025. Searches were performed in PubMed, Scopus, CINAHL Ultimate (EBSCOhost), and Web of Science using structured terms for AI/LLMs (eg, ChatGPT, generative AI, large language models) combined with healthcare education and training concepts. Eligible studies addressed AI-based technologies within healthcare education or training contexts; studies focused solely on clinical practice or non-educational applications were excluded. Bibliographic metadata from PubMed (TXT) and Scopus (BIB) were merged and analyzed using bibliometrix/Biblioshiny (R) and VOSviewer to quantify productivity, collaboration (including international co-authorship), and keyword co-occurrence patterns. Results: The dataset comprised 262 documents from 158 sources, with an annual publication growth rate of 36.58% and a mean document age of 1.83 years. A total of 1,351 authors contributed (mean 5.97 co-authors per document); international co-authored publications accounted for 13.36%. Most records were journal articles (253/262), followed by letters (8/262) and one conference paper. Annual output rose from 52 (2023) to 113 (2024; +117.3%), then decreased to 97 (2025; −14.2% vs 2024) while remaining above 2023 levels. JMIR Medical Education published the most articles on this topic (34/262), followed by Scientific Reports (9/262) and BMC Medical Education (7/262). Frequent keywords included “humans” (n=144), “artificial intelligence” (n=82), “generative AI” (n=30), and “large language models” (n=20); education-focused terms such as “educational measurement/methods” were also prominent (n=76). Conclusions: Research on LLMs and exam performance in healthcare education expanded rapidly from 2023–2025, with publication activity concentrated in a limited set of journals and relatively low international collaboration. Thematic patterns emphasize assessment-related outcomes and LLM/ChatGPT performance, supporting the need for more comparable, transparent reporting (eg, prompts and model versions) and education-centered outcomes beyond accuracy in future studies.

Background: Accurate assessment of surgical margins is essential in the treatment of squamous cell carcinoma (SCC) of the upper aerodigestive tract or cutaneous origin, as well as basal cell carcinoma (BCC). Intraoperative frozen-section analysis is the current standard but is time-consuming and requires coordination among surgical and pathology teams. Reflectance confocal microscopy offers rapid, real-time evaluation of surgical margins and may provide diagnostic information comparable to frozen-section analysis, while enabling the development of a reference atlas for tumor visualization. Objective: The HISTOBLOC study aims to evaluate the concordance between confocal microscopy and intraoperative frozen-section examination for assessing surgical margins in SCC and BCC. A secondary objective is to compile a confocal imaging reference atlas to document tumor features and support consistent interpretation Methods: HISTOBLOC is a prospective, monocentric, randomized pilot study conducted at the Institut de Cancérologie de Lorraine, a nonprofit comprehensive cancer institute. Patients undergoing surgical excision for SCC or BCC have their margins assessed using both confocal microscopy and frozen-section analysis. The study measure concordance between the two methods and the time required for intraoperative margin assessment. Results: Patient recruitment for the study began on July 26, 2023, and was completed in June 4, 2025. All patients were enrolled according to the approved study protocol. Experimental procedures have been conducted in all recruited participants, and data collection has been completed. The results are currently undergoing statistical analysis and interpretation. Conclusions: This protocol describes a study designed to determine whether confocal microscopy can provide rapid, reliable intraoperative margin assessment comparable to frozen-section analysis, and to generate a reference atlas for clinical and research use.

Background: During crisis, individuals increasingly rely on digital platforms for information, communication, and emotional support. Cyber behavior - which encompasses online engagement, security practices, and information sharing is shaped by cognitive and emotional factors such as awareness, knowledge, and anxiety. Understanding these relationships is crucial for promoting digital resilience and well-being during wartime and other large-scale emergencies. Objective: This study sought to examine how cybersecurity awareness, knowledge, and crisis-related anxiety influence cyber behavior and well-being during a national crisis. Drawing on the Protection Motivation Theory (PMT), the study further explored how cognitive and affective responses interact to shape individuals’ online engagement patterns and subsequent psychological outcomes. Methods: A cross-sectional online survey was conducted among 512 Israeli adults aged 18-65 during the ongoing war period (January 2024). Standardized psychometric instruments were used, including the WHO Well-Being Index, DASS-21 Stress subscale, and the Connor-Davidson Resilience Scale (CD-RISC-10). Media engagement was assessed across ten distinct digital activities. Data analysis employed a comprehensive approach, including cluster analysis, exploratory factor analysis (EFA), regression modeling, and path analysis. Results: Cluster analysis yielded two distinct segments: a high media engagement cluster and a low media engagement cluster. Participants in the high-engagement group reported significantly higher stress levels and greater utilization of digital media for news consumption, social networking, and charitable donations (p < .001). Furthermore, exploratory factor analysis revealed three salient dimensions of media usage: active, passive, and institutional. Path analysis indicated that stress was a positive predictor of all forms of media engagement. In predicting well-being, active media use (β = .12, p = .006) and resilience (β = .30, p < .001) were positively associated, whereas passive media use demonstrated a marginally negative association (β = -.08, p = .078). Conclusions: Cyber behavior during wartime is demonstrably influenced by both cognitive awareness and emotional stress. Specifically, while anxiety and stress tend to increase online engagement, overexposure to digital media may simultaneously well-being. Therefore, enhancing cyber literacy, cultivating emotional resilience, and promoting balanced media consumption are crucial strategies that can mitigate psychological distress and significantly strengthen digital resilience during crises.

Ambient AI technologies are increasingly marketed as solutions to reduce clinician burden and
improve care efficiency, yet real-world performance varies widely across clinical settings.
Healthcare provider organizations face challenges in determining which aspects of ambient AI
performance matter most and how to obtain meaningful information about those aspects from
vendors or through internal evaluation. This article presents a shared mental model to guide
health system leaders in conceptualizing ambient AI performance across three interdependent
dimensions: technical, interface, and system-level. For each dimension, we outline the types of
information relevant to assessment, what vendors should reasonably be expected to provide, and
how healthcare provider organizations can conduct their own evaluations to contextualize,
verify, or supplement vendor claims. By integrating both vendor and health-system perspectives,
this work offers a grounded, practical structure to support organizations of all sizes in
understanding and making informed decisions about ambient AI technologies.

Scientific writing is a core competency in medical education and academic medicine, yet it remains a major barrier for early-career clinicians and researchers, particularly in resource-limited settings. Common challenges include limited formal training in scientific writing, heavy clinical workloads, restricted access to journals and editorial support, and difficulties writing in English as a non-native language. Recent advances in artificial intelligence (AI) have generated widespread interest as potential tools to support academic writing. However, most available guidance focuses on proprietary platforms or presents overly generic advice generated by large language models, offering limited practical value for trainees and educators working under real-world constraints.
In this Viewpoint, we present a practice-informed, tool-agnostic workflow illustrating how freely accessible or freemium AI tools may be used to support scientific writing in medical research and education. Rather than claiming empirical validation or comparative performance, we offer a scholarly perspective grounded in the lived experience of medical educators and researchers who routinely supervise early-career authors. We argue that the educational value of AI lies not in content generation, but in supporting core academic skills such as literature navigation, structured reading, drafting clarity, and iterative revision.
We outline key functional categories of free AI tools relevant to scientific writing, including literature discovery, reference management, PDF-based summarization, drafting and editing support, and table or figure preparation. We also address important limitations, including learning curves, internet connectivity requirements, data privacy concerns, disciplinary variability, and the risk of over-reliance on AI at the expense of critical thinking. Ethical considerations and transparency in AI use are emphasized in line with current editorial guidance.
We conclude that, when used deliberately and ethically, free AI tools may help to lower barriers to scientific writing for medical trainees and early-career researchers. Their greatest educational value lies in complementing—not replacing—foundational research skills, thereby supporting more equitable

Background: Inclusive physical education (PE) plays an important role in promoting participation and development among students with different abilities. However, many teachers do not have adequate tools to modify PE activities to meet these diverse needs. In addition, parents are essential partners, as their involvement helps to reinforce strategies and provide useful information about their children. While online platforms provide a practical way to deliver such solutions, only a few are intentionally created to support both teachers and parents in implementing inclusive PE learning. Objective: This study aimed to develop an online platform that provides inclusion strategies for PE teachers and to examine how teachers and parents perceived its usability, acceptability, and overall usefulness using a mixed methods approach. Methods: A mixed methods research design was adopted in two phases. Phase 1 involved the development of the platform through expert consultation and literature review with feedback from educators. Phase 2 focused on user evaluation and involved usability testing using the System Usability Scale (SUS) and the Questionnaire for User Interaction Satisfaction (QUIS), alongside task performance metrics. Semi-structured interviews were also conducted with PE teachers (n=8) and parents (n = 8). Quantitative data were analyzed descriptively and with inferential statistics, while qualitative responses were coded thematically and the results were integrated using joint display. Results: All participants successfully completed the assigned tasks except few instances of minor difficulty during task completion (14 total errors across 136 task attempts). The Platform satisfaction scores were good as reported by PE teachers (8.03±1.59) and parents (8.13±1.06). QUIS scores were high among PE teachers (overall reaction: 8.03 ± 1.59; learning: 9.69 ± 0.40) and parents (overall reaction: 8.13 ± 1.06; learning: 8.63 ± 1.57). Mixed-methods integration showed strong convergence between high satisfaction scores and positive professional value quotes. However, divergence was noted in the learning domain, as high scores contrasted with reported uncertainty among new users. Lower system capability scores from parents (6.69 ± 2.25) were consistent with qualitative concerns about navigation inefficiencies and slow platform response. Desktop design was praised, while the mobile view was considered visually dense. Conclusions: The online platform provides strong usability and satisfaction among PE teachers and parents. Future work will involve improved implementation and evaluation of its impact on students’ participation outcomes.

Background: Young people increasingly experience mental health challenges and often turn to the internet for support. Self-guided digital mental health promotion services have become widely used resources for youth seeking help and guidance. These platforms offer accessible, anonymous support, yet little is known about the concerns young people articulate when engaging with them. Objective: This study examines inquiries submitted to a digital letterbox on one of Denmark’s most widely used digital mental health promotion services, Mindhelper.dk, to identify recurring themes in young people's inquiries about mental health and well-being. In addition, it explores how gender influences these experiences in the context of engagement with a self-guided digital platform. Methods: Employing an inductive analysis strategy and a grounded theory–inspired coding framework, this study analyzes a dataset of 2,523 inquiries submitted to the Mindhelper letterbox between March 2016 and August 2023. The archive provides rare, unsolicited first-person accounts from young people in moments of emotional vulnerability, providing immediate and authentic insights into their mental health concerns. Results: The analysis identifies 17 recurring themes that reflect the mental health challenges young people seek help for. These themes are grouped into three overarching analytical categories: Social Relations and Social Contexts, Emotional Life, and Body and Illness, with the first two dominating the material. The most prominent themes include Sociality, Love Life, Unease, Self-Criticism and Insecurity, and Communication and Reaching Out for Support. The intersection of themes underscores the central role of social relationships in young people's mental health and well-being, with frequent co-occurrence of inquiries addressing both Love Life and Sociality. Regardless of gender, users frequently inquire about Sociality and Love Life, indicating shared concerns related to social relationships. However, girls were markedly overrepresented among inquirers, highlighting potential gender differences in help-seeking behavior. Conclusions: Social relationships play a central role in young people's lives, yet many also face emotional struggles, particularly related to anxiety, self-esteem, and despair. The letterbox serves as an important help-seeking channel for youth who may lack access to support elsewhere, with a marked overrepresentation of girls, indicating gender patterns in help-seeking behavior. This study provides novel insights into the mental health challenges Danish youth face and their engagement with digital support services, informing the design of targeted, gender-sensitive self-help content and guiding future efforts to promote well-being and reduce barriers to help-seeking.

Background: The NHS 10 Year Health Plan emphasises an increasing shift towards digital healthcare delivery. However, there is limited research on how best to support, engage, and include individuals who are digitally excluded. As healthcare services become more digitally driven, evidence-based interventions are needed to address digital exclusion and ensure equitable access to care, particularly for people living with long-term conditions. Objective: This study aimed to evaluate the feasibility and acceptability of providing digital literacy training alongside a digital health intervention (DHI), compared with a DHI alone. Kidney Beam, a DHI designed to promote physical activity and improve quality of life in people living with chronic kidney disease (CKD), was used as an exemplar intervention. Methods: A mixed-methods, single-site pilot randomised controlled trial recruited 40 adults with CKD who were digitally excluded. Digital exclusion was defined as lacking access to a Wi-Fi–enabled digital device or scoring <7 on a Digital Health Literacy Screening tool (DHLS). Participants were randomised 1:1 to receive either the Ex-Tab digital inclusion intervention alongside Kidney Beam or Kidney Beam alone. Participants in the intervention group received a Wi-Fi–enabled iPad with Kidney Beam pre-installed, digital literacy training, and ongoing support to access the 12-week Kidney Beam programme, which included twice-weekly live exercise and education sessions. The control group received sign-up instructions for Kidney Beam only.
Feasibility outcomes were assessed against a priori progression criteria and included screening, recruitment, retention, adherence, safety, and acceptability. Secondary outcomes included the Kidney Disease Quality of Life questionnaire, Chalder Fatigue Questionnaire, and Patient Health Questionnaire-4 (PHQ-4). Outcomes were measured at baseline and 12 weeks. Acceptability and user experience were explored through semi-structured interviews with participants from both groups at 12 weeks (n=25). Results: Between September 2023 and September 2024, 169 individuals were screened and 40 enrolled (median age 66.5 years; 50% male; median DHLS score 4). Twenty-one participants were randomised to the Ex-Tab group and 19 to the control group. Thirty-five participants (88%) completed the 12-week follow-up (Ex-Tab n=18; control n=17).
All pre-specified feasibility criteria for recruitment, retention, adherence, and safety were met. Qualitative findings indicated that the tablet loan and digital literacy training were acceptable and highly valued, enhancing confidence, motivation, and engagement with the DHI. Providing loaned devices was particularly important for overcoming access barriers, especially for participants unable to afford their own. Conclusions: Providing Wi-Fi–enabled devices and digital literacy training alongside a DHI was feasible and acceptable for people with lower levels of digital literacy. Findings support progression to a future definitive multicentre trial or implementation study and offer transferable insights for the design of digital inclusion strategies across other long-term health conditions. Clinical Trial: The study was approved by the Bromley NHS Research Ethics Committee (Ref: 21/LO/0243) and registered on ClinicalTrials.gov (NCT04872933).

Background: The nursing field is facing unprecedented challenges driven by an explosion of heterogeneous data, persistent data silos, and increasing complexity in clinical decision-making. These issues underscore the urgent need for a systematic, integrative framework to organize and leverage nursing information effectively. Objective: This paper aims to conceptualize “Nursing Omics” a novel, multi-omics inspired integrative framework for future-oriented nursing informatics. Methods: Using a theoretical development approach, we draw on paradigms from genomics, proteomics, and other omics disciplines, integrating core principles from nursing informatics, systems science, and data science to construct a coherent conceptual architecture. Results: We propose a formal definition of Nursing-Omics and introduce a multidimensional integrative framework comprising the Intervenomics, Responsomics, Behaviomics, Exposomics, Experienomics. The framework is grounded in four foundational principles: holism, dynamism, data-driven insight, and individualization. Conclusions: Nursing-Omics offers a transformative paradigm for the systematic integration of nursing data, enabling precision decision-making, accelerating knowledge generation, and advancing intelligent, person-centered care. It represents a critical direction for the evolution of nursing informatics in the era of digital health. Clinical Trial: NO

Introduction: Large Language Models (LLMs) are increasingly applied in medical contexts, offering benefits for clinical decision-making, education, and patient communication. However, bias in LLM outputs may exacerbate healthcare disparities and compromise trust. This systematic review will examine how bias is identified, measured, and mitigated in healthcare use cases of medical LLMs.
Methods and Analysis: A systematic search will be conducted in EMBASE, MEDLINE, PsycINFO, PubMed, ACL Anthology, ACM Digital Library, ArXiv, MedRxiv, and BioRxiv. Studies will be included if they investigate bias in LLM applications within healthcare, report experimental findings, and are published in English from 2017 onwards. Grey literature with adequate methodological detail will also be considered. Findings will be synthesised using a narrative approach due to anticipated methodological heterogeneity.
Ethics and Dissemination: As a secondary analysis of published literature, ethical approval is not required. Results will be disseminated through peer-reviewed publications, academic conferences, and open-access repositories to inform responsible LLM deployment in healthcare.

Background: After non-curative resection for early gastric cancer (EGC) with endoscopic submucosal dissection (ESD), gastrectomy with lymphadenectomy is generally recommended. However, most patients are found to have no residual cancer in the stomach or regional lymph nodes, while surgery carries a considerable risk of postoperative complications. In Western settings, patients with EGC are often elderly and have concomitant comorbidities. Objective: In this study, we aim to assess the feasibility and safety of indocyanine-green (ICG) - guided lymphadenectomy with or without laparoscopic and endoscopic cooperative surgery (LECS) following non-curative ESD for EGC. Methods: A single-center phase 1 prospective trial. Patients with EGC treated with ESD within the expanded criteria will be considered for inclusion, provided the resection was non-curative (eCuraC2). For patients with radically resected EGC, ICG-guided lymphadenectomy alone will be performed. In those with a non-radically resected EGC, ICG-guided lymphadenectomy and LECS will be performed. The primary objective is to evaluate the safety of the procedure, defined as Clavien-Dindo grade III or more. The secondary endpoints include other complications, operation time, number of positive lymph nodes, short-term mortality, and health-related quality of life. Results: As of January 9th, 2026, no patients have yet been recruited to the trial. Conclusions: ICG-guided lymphadenectomy with or without LECS is an appealing and potentially promising treatment strategy following non-curative ESD for EGC. To the best of our knowledge, no previous studies from the Western world have been conducted on this subject.

Background:
Malaysia is a multicultural country with the main ethnic groups being Bumiputra, Chinese, and Indian. This creates a rich food culture with distinct dishes, cooking styles, and portion sizes, making dietary assessment challenging. Intake24 is a web-based 24-hour dietary recall system that automates data collection, reduces recall bias, and saves time.
Objective:
This paper describes a protocol for the development and relative validation of Intake24 Malaysia (Intake24-MY) for the Malaysian population.
Methods
This paper describes two phases in adapting Intake24-MY: (1) the development process and (2) the validation study. Phase 1 consists of the following components: (1a) system translation, (1b) food list development, (1c) portion-size estimation, (1d) food-composition data, (1e) small-scale and pilot testing, and (1f) user guide development. Phase (2a) single-meal validation study that will be conducted among 100 adults, comparing Intake24-MY with observed intake. Phase 2b) cross-sectional study conducted among 482 Malaysian adults to compare 4 days of dietary intake using Intake24-MY against an interviewer-led 24-hour dietary recall. A structured questionnaire will be used to assess the feedback on the usability of Intake24-MY. The Bland-Altman method will be used to determine the agreement between these methods.
Results:
Recruitment for the pilot study began in September 2025. The single-meal validation study has been ongoing and is scheduled for completion by March 2026. Recruitment for the relative validation is scheduled to begin in May 2026, following institutional review board approval from the Monash University Human Research Ethics Committee (MUHREC ID: 41337).
Conclusion
Intake24-MY is a comprehensive digital dietary assessment tool for Malaysia and will contribute to improving dietary assessment for the multi-ethnic population in Malaysia.

Background: The anesthesiology healthcare workers across various hospital levels in China were invited to participate in an electronic survey. Objective: The study aimed to assess the prevalence and impact of occupational burnout among anesthesiologists and anesthetic nurses in China, identifying key factors and providing a scientific basis for intervention strategies. The importance of this research lies in addressing the critical shortage of medical personnel in anesthesiology and its impact on healthcare quality. Methods: The primary goal was to provide a comprehensive analysis of occupational burnout among anesthesiologists and nurses in China using an electronic questionnaire. The questionnaire included assessments of occupational burnout, demographic and work-related information, work stress, interpersonal relationships, and health status. Results: A total of 1,465 participants were included across China. The response rate was 96.30%, with an overall burnout rate of 79.52%. Anesthesiologists had a burnout rate of 82.51%, and anesthetic nurses had a rate of 72.85%, showing a significant difference (P = 0.000). The prevalence of high emotional exhaustion and depersonalization was 45.80%, with anesthesiologists at 50.30% and nurses at 35.76%. Multivariable logistic regression analysis identified independent risk factors associated with burnout, including work environment, colleague relationships, and sleep quality for anesthesiologists, and experience, hospital level, and work intensity for anesthetic nurses. Conclusions: Occupational burnout is prevalent among anesthesiology professionals in China, with significant implications for individual well-being and patient care. The study's findings call for targeted interventions, such as improving work environments, enhancing education and training, and establishing support systems to mitigate burnout and promote work-life balance. Future research should focus on developing and evaluating effective intervention measures to ensure the well-being of medical professionals and the quality of healthcare services.

Background: Artificial intelligence (AI) is transforming medicine by enhancing care and reducing administrative tasks, and facilitating research. AI also raises many concerns, including a lack of clinical context awareness, data dependence, and the absence of ethical judgment. As future practitioners, medical students must be prepared for these changes. Most studies assessing students' attitudes and knowledge were conducted before artificial intelligence became accessible and tailored to the needs of the population. Therefore, how medical students actually use AI remains largely unexplored. Objective: This study explores French medical students' knowledge and attitudes toward AI. Methods: A mixed-methods study was conducted in 2025 among French medical students in their 4th to 6th year of school, corresponding to the clerkship year. An online survey adapted from Ten et al. 2025 included open-ended questions about AI definition and feelings toward AI, a Likert scale item to assess specific attitudes, and multiple-choice questions about the characteristics of the student. Quantitative analysis was performed using non-parametric tests (Kruskal-Wallis) to compare attitudes by AI knowledge level, academic years, career aspirations, and ranking within the class. Qualitative analysis was performed inductively. Results: Of 1,377 responses received, 1,342 were included. Students had a mean age of 23.1 years and were predominantly in their 5th year. Only 6% provided a correct definition of AI, while 51% gave incorrect responses. Attitudes toward AI were generally positive, with a mean score of 6.85, with significant differences by correct response to the definition (p <0.01; Unknown: 6.12, Incorrect: 6.84, Partially correct: 6.94, Correct: 6.88) and by career goals (p<0.01; clinical: 6.58; research: 6.83; private practice: 7.19). Regarding learning, 49% of students think that AI learning should be outside the curriculum, compared to 44%. Most of the students suggested AI training through multiple workshops
Qualitative analysis revealed five themes: Representation, Nuanced Optimism, Critical Consideration, Replacement, and AI Use. Students represent AI as a robot, as an improved search engine, or as an unlimited data source. Their nuanced optimism blends enthusiasm for efficient patient care and provides an opportunity to focus more on the patient relationship, with fears of dehumanization, energy costs, and skill regression. Critical consideration underscores distrust in ethical dilemmas and data security risks. Replacement concerns arise over shifting professional roles, though many believe human empathy remains irreplaceable. For AI use, students highlight administrative aid, personalized training, and clinical support. Conclusions: There is growing interest in AI among medical students, accompanied by new ecological concerns and fears of skill loss. Students seem to have learned to use AI on their own for learning. These results highlight the need to adapt training programs to include the responsible use of these technologies and how to use AI to its fullest potential.

Background: Background: Adolescence is a critical period for spinal and neuromuscular development, during which abnormal spinal curvature may progress rapidly and lead to long-term musculoskeletal dysfunction. Exercise therapy is widely recommended as a non-surgical intervention; however, substantial individual variability in treatment response limits its clinical effectiveness. Although multidimensional data on body composition and spinal function are routinely collected in schools and rehabilitation clinics, these data are rarely integrated into intervention decision-making. Current screening and treatment selection still rely largely on visual assessment and simple angular measurements, and validated tools for identifying adolescents most likely to benefit from specific exercise therapies are lacking. Objective: Objective: This study aimed to evaluate the effects of a 12-week spiral muscle chain training (SPS) and combined exercise therapy incorporating proprioceptive neuromuscular facilitation (PNF), and to develop an interpretable machine learning–based predictive model to support personalized exercise therapy planning for adolescents with abnormal spinal curvature. Methods: Methods: The data for this study were derived from a 12-week randomized controlled trial of exercise therapy. A total of 125 middle and high school students with abnormal spinal curvature were recruited from schools and randomly assigned to a spiral muscle chain training group (n = 61) or a combined exercise therapy group (n = 64). All interventions were conducted offline. Baseline and post-intervention assessments of body composition and spinal health were performed using standardized clinical measurements. Singular value decomposition–based principal component analysis (SVD-PCA) was applied to extract principal components representing spinal mobility and balance. These components, together with demographic and clinical indicators, were used to construct predictive models using four machine learning algorithms: K-nearest neighbors (KNN), random forest (RF), support vector machine (SVM), and extreme gradient boosting (XGBoost). Model performance was evaluated, and SHapley Additive exPlanations (SHAP) were used to interpret the optimal model. Results: Results: Both exercise therapies significantly improved spinal curvature, spinal mobility, and head, shoulder, and pelvic balance, with combined exercise therapy demonstrating superior efficacy. The reduction in angle of trunk inclination (ATI) was greater in the combined therapy group(P<0.001). SVD-PCA extracted three mobility-related principal components and one balance-related component from 21 spinal indicators, explaining 86.37% of the total variance. Among all models, the RF model achieved the best predictive performance (AUC=0.950, F1=0.857, BS=0.120). SHAP analysis identified exercise therapy type, kyphotic angle (KA), ATI, and spinal function–related principal components as the most influential predictors. Conclusions: Conclusions: Both SPS and combined exercise therapy effectively improve adolescent spinal curvature abnormalities, with SPS showing particular value for mild to moderate cases. Machine learning–based predictive models can integrate multidimensional spinal health data to provide interpretable and individualized predictions, supporting precision assessment and personalized intervention strategies for adolescents with abnormal spinal curvature.

Background: The global prevalence of pressure injuries is high and can cause severe infections, or death. Accurate staging is vital for effective intervention. Deep learning streamlines pressure injury assessment, enhances efficiency, and yields practical, accurate results. This scoping review summarized research on multi-modal deep learning for intelligent pressure ulcer recognition. Objective: It systematized models, training methods, and outcomes to identify the best systems for rapid detection and automated staging of pressure ulcers. Enhancing the timeliness, accuracy, and objectivity of diagnosis is the goal. Methods: We searched the following databases and sources: PubMed, the Cochrane Library, IEEE Xplore, and Web of Science. The scoping review was conducted in accordance with the JBI Scoping Review Methodology Group’s guidance and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Reviews guidelines. The study protocol was registered with the International Prospective Registry of Systematic Reviews (PROSPERO) on 12 December 2025 (registration number: CRD420251251573). Results: 15 articles were included: 26 models were involved, including AlexNet; VGG16; ResNet18; DenseNet121; SE-Swin Transformer; Cascade R-CNN; vision transformer (ViT); ConvNextV2; EfficientNetV2; Meta Former; TinyViT; CCM; BCM; ResNext + wFPN; SE-Inception; Mask-R-CNN; SE-ResNext101; Faster R-CNN; ResNet50; ResNet152; DenseNet201; EfficientNet-B4; YOLOv5; Inception-ResNet-v2; InceptionV3; MobilNetV2. The training methodology for intelligent pressure ulcer recognition models involves establishing an image database, processing images, and constructing the recognition model. Different models exhibit varying accuracy rates in staging pressure ulcers, with overall accuracy fluctuating between 54.84% and 93.71%. The DenseNet121 model achieved the highest recognition accuracy of 93.71%, while VGG16 was the most widely applied. The same model demonstrated significant variations in recognition accuracy across different studies. Conclusions: The multi-modal and deep learning-based intelligent recognition model for pressure injuries demonstrates high overall accuracy, enabling rapid automated staging of such injuries. Future research may explore optimized intelligent assistance systems to enhance the accuracy, objectivity, and efficiency of pressure injury diagnosis.

Background: Prolonged exposure to computer screens has been associated with visual fatigue and reduced visual comfort, which may in turn affect cognitive performance and concentration. While blue-enriched screen light and display settings are known to influence visual strain, their impact on short-term task performance under different backlight configurations remains insufficiently quantified from a human factors perspective. Objective: This study aimed to evaluate the effects of different computer screen backlight settings on user concentration, using typing speed as a quantitative proxy for task performance. Methods: A total of 22 adult participants performed standardized reading and typing tasks under different screen backlight conditions, including black text on a white background and white or orange text on a dark background. Screen illuminance and spectral characteristics were measured using a calibrated spectrometer. Typing speed was recorded after controlled reading periods, and statistical analyses were conducted to assess changes in performance across conditions. Results: Typing speed decreased significantly after 30 minutes of reading under a traditional black text on white background. In contrast, switching to a dark background with white text resulted in a significant increase in typing speed. Further improvement was observed when orange text was used on a dark background. Myopic diopter showed no significant correlation with changes in typing performance. Conclusions: Lower screen illuminance achieved through dark background display settings was associated with improved short-term task performance. These findings suggest that display configurations emphasizing reduced luminance may help maintain concentration during computer-based tasks and have implications for visual ergonomics and human-centered display design. Clinical Trial: Not applicable.

Background: Background Heart failure (HF) is a refractory disease with a global public health issue that is continuously increasing. Metabolic syndrome plays a crucial role in prevalence and mortality of HF. The triglyceride-glucose (TyG)-related obesity indices, such as body mass index (BMI), a body shape index (ABSI), and waist-to-height ratio (WHtR), have been recognized as a significant predictor of cardiovascular disease risk. Nevertheless, the predictive value of these makers for HF prevalence and their association between all-cause mortality in general populations remains unclear. Objective: in this study, we aimed to evaluate their association with prevalence and all-cause mortality among HF patients using machine learning techniques. Methods: The U.S. National Health and Nutrition Examination Survey (NHANES) (2001-2018) database provided all the data for this study. The status of the participants was followed through December 31, 2019. Participants were categorized into a non-HF group and a HF group. Weighted binary logistic regression was performed to evaluate the independent associations between the TyG-related obesity indices and HF. Meanwhile, subgroup analysis was performed to confirm the reliability of the associations observed among different population. Restricted cubic spline (RCS) models were utilized to delineate whether the relationship is non-linear. Random forest analysis and Boruta algorithm were adopted to assess the predictive value of each biomarker for the prevalence of HF. Receiver operating characteristic (ROC) curves were generated to assess the predictive performance. Additionally, those biomarkers were categorized into two groups based on threshold derived from the maximally selected rank statistics (MSRS). Kaplan-Meier survival analysis and weighted Cox regression models were employed to explore the association between each TyG-related obesity indices and all-cause mortality among HF patients. Results: 40,908 participants (1,174 HF patients) were encompassed in this retrospective study. In the fully adjusted model, TyG-BMI, TyG-ABSI, and TyG-WHtR exhibited higher odds ratio (OR) than TyG alone. TyG-ABSI exhibited the strongest association both as a continuous variable and across quartiles, demonstrating a significant near-linear positive dose-response relationship with HF risk. RCS analysis further confirmed a linear relationship between TyG-related obesity indices and HF risk. The ROC curve analysis demonstrated that TyG-ABSI had the best predictive performance for HF risk (AUC: 0.721, 95% CI: 0.690–0.736). Random forest analyses and Boruta algorithm identified those biomarkers as an important clinical feature. Subgroup analysis revealed no significant interactions across all subgroups, except for age. During a median follow-up of 9 years, a total of 566 deaths were documented, when stratified by the MSRS-derived optimal cutoff value, Kaplan-Meier survival analysis and Cox regression model demonstrated significantly worse overall survival for the higher TyG-ABSI group (HR:1.44, 95% CI=1.11-1.86, P=0.006), each standard deviation increment in TyG-ABSI was associated with an 11% increment all-cause mortality risk among HF patients. Conclusions: Our study suggests that TyG-BMI, TyG-ABSI and TyG-WHtR are associated with increased odds of HF in the U.S. TyG-ABSI demonstrate the best predicted performance and expect to become more effective metrics for improving risk stratification. TyG-ABSI is independently associated with increased all-cause mortality risk in HF patients, highlighting its potential as a useful tool in aiding personalized management.

Background: Parkinson’s disease (PD) is a progressive neurodegenerative disorder that poses complex challenges for persons with Parkinson’s (PwP), informal caregivers, and healthcare professionals. With growing interest in digital and predictive Artificial Intelligence (AI) tools for disease management, understanding the needs and digital readiness of these stakeholder groups is crucial. Objective: This work aims to (1) identify digital practices for PD management among PwP, at‑risk individuals, caregivers, and healthcare professionals; (2) compare these practices across groups; (3) explore stakeholder desires for AI-based tools; and (4) assess alignments and gaps to inform tailored AI solutions. Methods: An anonymous cross-sectional online survey of exploratory nature was distributed (from Dec. 2024 to Oct. 2025) in five languages. It was completed by 255 respondents. Descriptive statistics summarized responses to 41 questions, including stakeholder-specific items. Chi-square tests were performed to examine stakeholder differences in desired AI-features. Results: : Interest in predictive AI was high across stakeholder groups. Symptom-tracking was the most desired feature (selected by >76% of respondents); however, stakeholder priorities diverged in other areas. Healthcare professionals rated improving patient and informal caregiver engagement as significantly more important than PwP did, χ²(1, N=205)=34.78, p<.001, Cramer’s V=0.41. Despite considerable interest, the reported use of digital tools was limited, as most PwP did not use symptom-tracking apps or wearables, nor were they currently monitoring their condition, although many expressed intentions to begin. Conclusions: While AI tools were viewed positively across groups, there were significant gaps in current usage. Stakeholder-specific preferences, including informal caregiver engagement and preventive lifestyle guidance, highlight the importance of tailored design. These findings offer early-stage insight to guide development of future AI-based solutions for PD.

Background: : Stroke remains a leading cause of motor disability globally. Functional electrical stimulation (FES) has emerged as a promising neurorehabilitation modality, but its comparative efficacy, optimal application parameters, and long-term sustainability remain incompletely characterized. Objective: To synthesize evidence from randomized controlled trials and systematic reviews published between 2021 and 2025 regarding the effectiveness of FES interventions for upper and lower limb motor recovery in post-stroke populations. Methods: A comprehensive literature search was conducted across PubMed, Scopus, Web of Science, and Cochrane Library databases. Studies were selected based on PRISMA 2020 criteria. Quality appraisal was performed using the Physiotherapy Evidence Database (PEDro) scale and Cochrane Risk of Bias 2 tool. Quantitative synthesis was conducted using random-effects meta-analyses. Results: Twenty-seven studies (n=2,309 stroke participants) were included, encompassing diverse FES modalities: manually controlled, electromyography-triggered, brain-computer interface-controlled, and hybrid systems. Meta-analytic findings demonstrated that FES combined with occupational therapy produced significantly greater improvements in upper limb motor function (Fugl-Meyer Assessment: mean difference [MD] = 5.08, 95% confidence interval [CI] 2.46-7.71) compared to standard care alone. Brain-computer interface-controlled FES achieved superior outcomes (standardized mean difference [SMD] = 0.73, 95% CI 0.26-1.20) particularly when paired with action observation tasks. For lower limb recovery, FES reduced foot drop severity and enhanced gait parameters, with 52% of participants achieving independent walking. Cost-effectiveness analysis demonstrated long-term value (£15,406 per quality-adjusted life year). Adverse events were minimal, primarily limited to temporary skin irritation. Conclusions: FES represents a viable, evidence-supported adjunctive intervention for post-stroke motor recovery across subacute and chronic phases. Emerging technologies integrating brain-computer interfaces and artificial intelligence offer enhanced personalization and efficacy. Future research should prioritize real-world implementation trials, long-term follow-up protocols, and mechanisms underlying neuroplastic adaptations.

Background: Medical and welfare facilities in the Noto region of Japan were severely affected by the 2024 Noto Peninsula earthquake and the subsequent torrential rains. Staff members working in these facilities have been disaster victims and frontline caregivers and face prolonged restoration work with limited psychological support. Nonverbal social robots have been designed to provide companionship and emotional comfort. However, their effects on health-related quality of life (QoL) and well-being among care staff in disaster-affected settings are unknown. Objective: This study aimed to investigate whether introducing a nonverbal artificial intelligence (AI) communication robot can improve QoL and subjective well‑being in care facility staff working under disaster conditions. The secondary objective was to assess the safety, acceptability, and intention to continue using the robot. Methods: An ABAB intervention design was implemented between February and June 2025. After a 2‑week baseline, staff in dementia care, general care, and short‑stay units received the robot intervention for 2 weeks (A1), followed by a 2‑week withdrawal (B1), re‑intervention (A2), and final withdrawal (B2). The questionnaires were administered at the end of each phase. Primary outcomes were health‑related QoL (EQ‑5D‑5L), well‑being (WHO‑5 Well‑Being Index), and mental health continuum (MHC‑SF). Secondary outcomes included safety (three Likert‑scale items), acceptability (17 semantic‑differential items), and interaction frequency. Friedman tests were used to compare outcomes across phases, with Wilcoxon signed-rank tests and Bonferroni correction for post-hoc comparisons. Only participants with complete data across all phases were analyzed. Results: Of the 58 staff completing baseline assessments, 49 provided complete data (25 dementia care, 12 general care, 12 short‑stay). The participants were predominantly female, with a median age in the fifth decade; 75.7% reported personal disaster damage. The median baseline EQ‑5D‑5L utility, WHO‑5 percentage, and MHC‑SF scores were approximately 0.93, 60%, and 35 points, respectively. Interaction frequency with the robot significantly increased during the intervention phases, but Friedman tests showed no significant differences in EQ‑5D‑5L, WHO‑5, or MHC‑SF scores across the ABAB phases within or across units. Safety outcomes and the intention to continue use did not differ between the intervention and withdrawal phases, and no adverse events were reported. Acceptability improved for items, such as “felt calm,” “liked,” and “felt peaceful” in the dementia care unit and for “competent” and “peaceful” in the pooled analysis. However, these effects were insignificant after Bonferroni correction. Conclusions: In this study, the short-term use of a nonverbal AI communication robot did not lead to measurable improvements in QoL or well-being. Nonetheless, the increased interaction and positive acceptability ratings suggest that the robot was well-received and could be safely and feasibly deployed in disaster settings. Long-term studies with larger samples are required to determine whether such robots can provide meaningful mental health support to healthcare workers. Clinical Trial: Not applicable.

Background: Mentalization is a core human capacity involving the interpretation of one’s own and others’ behavior in terms of underlying mental states. Within the Mentalization-Based Treatment (MBT) framework, this capacity is described along multiple dimensions integrating cognitive, affective, relational, and regulatory processes. Large language models (LLMs) have recently shown an ability to generate linguistically reflective discourse, raising questions about whether the formal linguistic structure of mentalization can be reproduced independently of experiential and affective processes. This study investigates whether LLM outputs can be systematically evaluated as reflecting the linguistic structure of mentalization without implying psychological mentalization or theory of mind. Objective: The aim of this study is to assess whether a large language model can generate outputs that are structurally coherent with established MBT dimensions, and to determine the extent to which such outputs are recognizable as formally mentalizing by expert clinicians. The study introduces and operationalizes the concept of algorithmic reflectivity, defined as a formally coherent but non-experiential linguistic phenomenon. Methods: A comparative, descriptive methodological design was adopted. Fifty dialogic interactions between a large language model and human participants were generated under standardized conditions. At the end of each interaction, the model produced a narrative mentalization profile structured along MBT dimensions. Five psychiatrists with formal MBT training independently and blindly evaluated all profiles. Evaluations used 5-point Likert scales assessing (1) evaluative coherence, (2) argumentative coherence, and (3) global quality across the MBT dimensions. Interrater reliability was estimated using the intraclass correlation coefficient (ICC[3,1]). Descriptive statistics were used to summarize score distributions and variability. Results: Across all dimensions, mean scores ranged from 3.63 to 3.98, indicating moderate to high structural coherence. Interrater reliability was substantial to high, with ICC values ranging from 0.60 to 0.84. The highest scores were observed for dimensions related to explicitness, synthesis, and self–other differentiation, while lower scores were observed for integration between internal states and external context. Qualitative comments consistently described the outputs as linguistically organized and clinically interpretable, but affectively neutral and weakly contextualized. No evidence of experiential grounding, affective modulation, or intentional agency was observed. Conclusions: The findings indicate that LLMs can reliably reproduce the formal linguistic structure associated with mentalization as defined by MBT, generating outputs that expert clinicians recognize as structurally coherent. However, this capacity reflects algorithmic reflectivity rather than psychological mentalization: a form of linguistic coherence without experiential, affective, or relational grounding. The study supports a clear conceptual distinction between mentalization as a psychological function and its discursive structure as a linguistic phenomenon. These results suggest that LLMs may serve as methodological tools for research and training on reflective language, while remaining unsuitable for unsupervised clinical application.

Background: Self-assessment is a key requirement for lifelong learning in medicine. Evidence from gender-related research indicates that important moderators affecting self-assessment are influenced by gender. Therefore, systematic gender differences in the accuracy of self-assessment may be assumed. Objective: The present study aims to examine gender differences in medical students’ self-assessment. Specifically, this study addresses two research questions: (1) Are there systematic gender differences in medical students' self-assessment accuracy? (2) What is the magnitude of these gender differences when accounting for academic progress and knowledge? Methods: Medical students from 3 cohorts at the Medical School OWL were surveyed in 3 waves between April 2023 and April 2024 during the Progress Test Medicine (PTM). Prior to answering the test, students were asked to indicate the percentage of the PTM questions they expected to answer correctly in five knowledge areas. Self-assessment accuracy was calculated as the difference between the subjective self-assessment and the objective test score. Linear mixed models (LMMs) were used to analyze the influence of gender on students’ self-assessment accuracy while accounting for academic progress and knowledge. Results: A total of 165 students participated in this study (66.58% women, 33.42% men; age: M=21.96 years, SD=3.61). Across all models, female students rated themselves significantly less accurately than their male peers. The observed gender effect ranged from -3.74 to -6.08 percentage points. Conclusions: The results indicated systematic gender differences in medical students’ self-assessment, in favor of male students, with a magnitude comparable to the average knowledge acquired in an entire semester of study. In view of the potentially negative consequences of inaccurate self-assessment, targeted support for developing realistic self-assessment during medical studies may be particularly beneficial for female students.

Background: Mobile health (mHealth) and online video are increasingly central to cardiology education and point-of-care decision support. However, little is known about how simple design choices—such as mobile-first web layouts and captioned video—function as equity enablers across income settings when examined with multi-country learning analytics. Objective: This exploratory ecological study used real-world, cross-platform learning analytics from a French-language cardiology mHealth education initiative to quantify how mobile web access and captioned YouTube viewing varied across World Bank income groups and assess whether greater reliance on these access enablers was associated with poorer engagement. Methods: We analyzed country-level analytics from the École Numérique de Cardiologie (ENC) mobile-optimized website and companion YouTube channel over a 2-year period. Countries were grouped as high-, middle-, or low-income. Primary access indicators were the share of website sessions from mobile devices and the share of YouTube watch time with subtitles enabled (any language). Engagement outcomes included website bounce rate and time on page and YouTube average view duration, audience retention, and intentional views. We summarized medians by income group and explored associations using nonparametric tests, Spearman correlations, and median quantile regression. Results: Thirty-four countries contributed data (13 high-income, 14 middle-income, 7 low-income). Caption-enabled watch time showed a marked income gradient, increasing from 18.8% in high-income to 38.7% in middle-income and 60.9% in low-income groups, a caption equity gap of 42.1 percentage points between low- and high-income settings. Median mobile share of website sessions also rose with decreasing income (36.5%, 63.3%, and 81.4%, respectively). Income groups with higher caption use also had a higher share of intentional views and younger audiences. Greater reliance on mobile access was not independently associated with higher bounce rate or shorter time on page in quantile regression models. Conclusions: In this multi-country mHealth learning analytics case study, mobile-first web access and captioned video were used most intensively in lower-income settings and were not associated with penalties in basic engagement metrics. These findings support treating mobile-optimized design and systematic captioning, including non-French subtitles, as core, low-cost components of equitable digital cardiology and mHealth education, and suggest that simple analytics indicators can serve as equity-focused monitoring tools for global mHealth initiatives.

Background: Over the past decade, Europe has expanded school-based mental health prevention programs, yet the prevalence of mental disorders among children and adolescents remains high and has risen further since the COVID-19 pandemic. Digital interventions have proliferated, yet implementation gaps persist, limiting their impact. Objective: To synthesize quantitative, qualitative, and mixed-methods evidence on the facilitators and barriers to implementing digital and analog universal school-based mental health promotion programs for children and adolescents (ages 5–19) in European primary and secondary schools, and to examine how implementation quality is assessed and the role of the digital environment. Methods: A three-step search will be conducted across the interfaces PubMed, EBSCO, Clarivate Analytics, PubPsych, Fachportal Pädagogik, Google Scholar, relevant preprint servers, and the reference lists of all included sources of evidence. A first systematic search was completed in January 2026. Titles/abstracts and full texts will be screened independently by two reviewers, with disagreements resolved through discussion or a third reviewer. Methodological quality will be appraised by assessing the trustworthiness, relevance, and results of published papers. Data will be extracted using standardized JBI forms and analyzed separately into quantitative (descriptive statistics, possible meta-analysis) and qualitative (meta-aggregation) components, followed by a convergent, segregated synthesis to integrate findings. No deviations from the JBI mixed-methods systematic review methodology are anticipated. Results: A comprehensive PubMed search was conducted on January 6, 2026, and 614 records were retrieved after applying filters. Results are expected to be published by December 2026. Conclusions: By integrating quantitative and qualitative findings, this review will identify the key facilitators and barriers influencing the real‑world uptake of digital and analog school‑based mental‑health programs across Europe. Mapping these determinants onto implementation frameworks such as CFIR and RE‑AIM and linking them to program outcomes will yield actionable recommendations that can close the implementation gap, bolster sustainability, and improve mental‑health outcomes for children and adolescents in the post‑COVID era.

Background: Despite the high potential of artificial intelligence (AI) in diagnosing Alzheimer's disease, a profound gap exists between reported accuracy in ideal conditions and models' reliable performance in real-world clinical settings. Objective: This systematic analysis aimed to identify the root causes of this gap and propose practical solutions. Methods: We conducted a systematic analysis in accordance with PRISMA 2020, analyzing 56 studies (2013-2023). A qualitative content analysis was performed around four pillars: 1) Data repository characteristics, 2) Data preprocessing and model design, 3) Technical implementation frameworks, and 4) Performance evaluation protocols. Results: Results indicate a methodological transition towards standardized data repositories and modern AI frameworks. However, rapid algorithm development has outpaced the maturity required for clinical generalizability. Four key deficits were identified:
1. Data limitations due to reliance on restricted, low-diversity datasets (63% of studies used ADNI exclusively).
2. Insufficient standardization in preprocessing and modeling, prioritizing 'convenience' over 'generalizability'.
3. A disconnect between technical capabilities and critical clinical needs (only 7% focused on the crucial sMCI/pMCI distinction).
4. Deficiencies in evaluation protocols, notably scarce multi-center validation (only 7%) and inadequate reporting of comprehensive metrics (96% relied solely on Accuracy).
Practical solutions to address these deficits across data, modeling, and evaluation domains are prop osed. Conclusions: Transitioning from 'accuracy under ideal conditions' to 'reliability in real-world settings' is an unavoidable necessity. This requires investment in multi-center data repositories, alignment of models with clinical needs, and institutionalizing comprehensive evaluations. The findings and recommendations are generalizable to other domains of AI-based disease diagnosis.

Background: Digital technologies have the potential to support physical, cognitive, and social activity among older adults, but many small and medium-sized enterprises (SMEs) lack the resources to conduct meaningful codesign with end-users. Toolkits derived from rigorous codesign processes may offer a scalable mechanism for translating end-user priorities into real-world product development. Objective: This study aimed to (1) engage older adults in an extensive codesign process to identify priorities for digital technologies that support physical activity and reminiscence, (2) translate these findings into a practical developer-facing toolkit, and (3) evaluate the toolkit’s perceived utility and influence among digital technology SMEs. Methods: 157 participants (120 older, 7 younger, and 30 staff) across 15 community and care settings in England and Scotland engaged in 106 technology interaction sessions, 22 evaluation focus groups and 10 codesign workshops involving more than 20 digital technologies. Thematic analysis and structured card-ranking tasks were used to derive end-user priorities. Preliminary toolkits were created and provided to 10 UK-based SMEs who received small grants to apply the toolkit to active development projects. Developer reports and follow-up interviews were analysed thematically to identify perceived impacts on design decisions, product adaptations, and business outcomes. Results: Codesign activities generated seven cross-cutting themes: motivation, content, barriers, design and inclusivity, suitability, acceptability, and motivations to use. These were organised into three toolkit sections: general design principles, online physical-activity platforms, and virtual reality. Developers reported that the toolkits enhanced understanding of older adults’ needs, validated design decisions, and inspired new features. Reported impacts included improved usability, expanded accessibility options, increased content variety, clearer instructional design, enhanced social components, and reduced operational costs. SMEs also reported business benefits, including strengthened cases for investment and increased product uptake. Conclusions: Codesign-derived toolkits offer a scalable and cost-effective mechanism for translating older adults’ priorities into digital product development. SMEs perceived the toolkit as practical, relevant, and impactful for informing design choices. This approach complements, but does not replace, direct user involvement and may help accelerate inclusive digital-health innovation for ageing populations. Clinical Trial: n/a

Background: Drug information apps are widely used clinical decision support tools that improve prescribing accuracy, yet in low- and middle-income countries such as Cameroon they remain unregulated, raising safety concerns. Despite high smartphone penetration among doctors, no studies have assessed whether available apps meet local needs or regulatory standards. Objective: This study aimed to evaluate whether drug information apps available in Cameroon met doctors’ clinical information needs by assessing content completeness and usability, using criteria that combine national regulatory standards with breadth of clinically relevant information. Methods: We systematically evaluated drug information apps from the Apple App Store and Google Play Store in Cameroon (March–June 2025). Of 193 eligible apps, 100 were selected through stratified sampling. A framework of 33 drug characteristics grouped into six macro-types was developed and applied based on the Ministry of Public Health standards and clinical needs. Completeness was measured through breadth coverage and Ministry of Public Health compliance; usability was assessed by two independent clinical assessors using the Mobile App Rating Scale (MARS). Results: Nineteen percent of the apps were developed in Africa, with only one from Cameroon. Just three offered bilingual content, while 39% required paid subscription averaging USD $37 annually. Most apps had low completeness with major gaps in safety (contraindications, drug interactions), and quality assurance information (references and author credentials). Usability was limited, with only 15% rated as good quality. Conclusions: Since most drug information apps did not meet Ministry of Public Health standards or core clinical decision-making requirements, there is an urgent need for regulatory oversight and the development of safer, locally adapted prescribing tools. The framework introduced in this study offers a scalable, evidence-based approach that can be adopted across low- and middle-income countries to guide regulation, strengthen quality assurance, and establish globally relevant benchmarks for evaluating drug information apps.

Background: Medical graduate education increasingly uses blended and online delivery, although students' academic self-regulation may be shaped by different motivational and cognitive processes across learning contexts, with emotional factors potentially playing a complementary role. Understanding how these mechanisms operate and whether their structural relationships differ between online/blended and face-to-face formats can inform targeted educational supports. Objective: The present investigation developed and tested a comparative causal model of academic self-regulation among medical graduate students in online/blended versus face-to-face programs. We examined how key motivational constructs (eg, academic self-efficacy, task value, future orientation, perfectionism, and academic help-seeking), positive achievement emotions, and cognitive factors (cognitive academic engagement and need for closure) relate to academic self-regulation, and whether these relationships differ by learning context. Methods: The design was cross-sectional, comparative causal modeling. Participants were master’s-level students at Shahid Beheshti University of Medical Sciences enrolled in either face-to-face (population n=1554; sample n=310) or blended/online (population n=449; sample n=205) programs selected using cluster sampling. Data were collected using validated instruments measuring academic self-regulation (Bouffard scale), academic self-efficacy (Midgley et al), academic engagement (Schaufeli & Bakker), multidimensional perfectionism (Frost), academic help-seeking (Ryan & Pintrich), task value (Pintrich), future orientation (Seginer), need for closure (DeBacker & Crowson), and achievement emotions (AEQ; Pekrun et al). Data were analyzed using path analysis/structural equation modeling. Model fit was evaluated using χ²/df, CFI, GFI, AGFI, and RMSEA. Direct, indirect, and total effects were estimated for each group, and comparative interpretation focused on effect patterns and explained variance. Results: The hypothesized causal model reached an acceptable fit in both face-to-face and blended/online groups (χ²/df approximately <3; CFI/GFI/AGFI in the acceptable range; RMSEA approximately 0.02–0.05). In both groups, most of the specified direct effects reached statistical significance, while the indirect effects of exogenous variables on academic self-regulation through intermediate constructs were supported overall. Cognitive academic engagement and academic self-efficacy were important proximal predictors of academic self-regulation. The need for closure had a negative direct effect with regard to academic self-regulation. However, a previously specified direct effect from need for closure to self-regulated learning strategies could not be retained in the final revised model. In both cohorts, the indirect pathway from positive achievement emotions to academic self-regulation via cognitive engagement was not supported, indicating that positive emotions alone were insufficient to increase self-regulation through cognitive engagement. The model explained a substantial proportion of variance in academic self-regulation in both groups—being approximately 0.44 in face-to-face and 0.46 in blended/online students—indicating comparable overall explanatory power across learning contexts. Conclusions: A comparative causal model integrating motivational, emotional, and cognitive pathways provided an adequate explanation of academic self-regulation among medical graduate students in both face-to-face and blended/online formats. Findings highlight the central role of cognitive engagement and academic self-efficacy as proximal levers for supporting self-regulation across contexts. The lack of a supported indirect effect from positive emotions to self-regulation via cognitive engagement suggests that emotional experiences may not be enough unless they are accompanied by cognitively engaged learning behaviors. Considering motivational and cognitive mechanisms that together shape self-regulation within different delivery modes, educational interventions in medical graduate programs should focus on strengthening self-efficacy beliefs and cognitively engaged learning practices.

Background: Total Hip Arthroplasty (THA) is a common surgical procedure, and an increasing number of patients are turning to short-video platforms for information. Although Douyin and TikTok belong to the same parent company, they cater to distinct sociocultural environments. Objective: To compare the quality, content, and user engagement of THA-related videos, and to explore the different attitudes of medical professionals and patients on these two platforms. Methods: We systematically searched and analyzed 265 THA-related videos and 600 highly liked comments. Video quality was evaluated using the JAMA (Journal of the American Medical Association) benchmark, GQS (Global Quality Score), and DISCERN tools. The content and comment themes were categorized. Chi-square test with effect size analysis was used to compare categorical variables, while Mann–Whitney U test and Kruskal–Wallis H test were applied to compare differences in scores. Results: The majority of authors on Douyin were medical staff (97.71%), whereas on TikTok, the proportions of science communicators and patients/caregivers were higher (41.04% and 20.15%, respectively). There were significant differences in author backgrounds and content types between the two platforms (p<0.01). Douyin had higher median scores for JAMA and DISCERN (p<0.01), while no significant difference was found in GQS. Significant differences in comment sentiment and themes were observed across platforms, author identities, and content types (p<0.01). Conclusion: Despite technical similarities, Douyin and TikTok exhibit distinct ecosystems: Douyin maintains a doctor-centered, authority-driven model with higher content quality and greater user engagement; TikTok fosters a patient-centered, community-driven model that provides more abundant experience sharing. Conclusions: These differences reflect varying cultural attitudes toward medical authority and shared decision-making.

Background: Erectile dysfunction (ED) is strongly influenced by persistent misconceptions that delay help-seeking and limit engagement with effective care. Patient-centered digital strategies, including generative–artificial intelligence (AI) microlearning, may improve sexual-health literacy; however, real-world evidence in urological practice remains sparse. Objective: To evaluate whether a clinician-supervised generative-AI microlearning video improves ED-related knowledge in adult men attending routine outpatient care. Methods: This single-center pre–post study included 200 adult men in a university urology clinic. Participants completed an 8-item ED-myth questionnaire immediately before and after watching a 3-minute educational video. The narration script was drafted using a large-language model (ChatGPT-5) and iteratively reviewed by urologists for accuracy and cultural appropriateness. The primary outcome was the within-participant change in total correct responses (0–8). Subgroup analyses assessed effects across age (<40 vs ≥40), education level, and self-reported ED. Paired analyses and multivariable logistic regression were used (α=.05). Results: All participants completed the intervention (mean age 44.0, SD 11.6 years). Total correct responses increased from 3.77 to 6.56 (mean Δ=2.79; P<.001), indicating a large effect (Cohen’s d >1.0). Knowledge gains were consistent across subgroups, with greater improvements among those with lower education. Self-reported ED was independently associated with lower odds of achieving ≥2-point improvement (odds ratio 0.46, 95% CI 0.26–0.81; P=.01). No adverse events or technical difficulties occurred. Conclusions: A brief generative-AI microlearning video, when supervised by clinicians, substantially reduced ED-related misconceptions in routine care. AI-assisted microlearning may serve as a scalable, low-burden adjunct to enhance sexual-health literacy during urological consultations. Long-term retention and behavioral outcomes should be evaluated in future trials. Clinical Trial: Not applicable.

Background: Quality dashboards are essential tools in healthcare, providing integrated and visualized data to support decision-making. Continuous monitoring of key indicators is crucial for managing chronic diseases such as diabetes mellitus and improving outcomes Objective: The aim of the study was to develop a web-based quality control dashboard to improve diabetes care in the public primary care setting in Tandil, Argentina Methods: The dashboard was embedded into the web-based EHR system of Tandil's Health Information System through a multidisciplinary approach, including literature review, stakeholder consultation, SQL database queries, and data visualization using Apache Superset. Key quality indicators were developed, including patient demographics, comorbidities, and clinical outcomes. Usability was evaluated using the SUS. Results: The interactive dashboard enables efficient monitoring of diabetes care through 29 process and outcome indicators. It facilitates real-time tracking of key metrics such as HbA1c testing rates, blood pressure control, and medication withdrawal, allowing for the identification of care gaps and disparities. The dashboard provides intuitive visualizations that support resource allocation, quality of care, and evidence-based policy development, with a mean SUS score of 78.7, suggesting high usability. Conclusions: This dashboard is a development in harnessing health information for the advancement of diabetes management in resource-stressed settings.

Background: Smoking is common in Saudi Arabia, particularly among men. Religion plays a protective role against smoking and serves as a motivator for quitting. Faith-based interventions have shown positive effects in supporting smoking cessation among Muslims who smoke, but few studies have tested their acceptability when delivered via mobile phone messaging. Objective: The aim of this pilot randomized controlled trial (RCT) was to evaluate the feasibility and acceptability of an Islamic-based smoking cessation intervention delivered via WhatsApp messaging in Saudi Arabia. Methods: This study was a two-arm RCT involving adult Muslim smokers who used cigarettes, waterpipe, or both, with participants randomized in a 1:1 ratio to either the intervention or control group. The intervention messages were co-designed with religious leaders and informed by formative research with Muslim current and former smokers. The intervention group received both religious and smoking-related health messages, while the control group received smoking-related health messages only. The intervention lasted for 21 days, during which participants received two messages per day, one in the morning and one in the evening. The primary outcomes were the feasibility and acceptability of the intervention. Results: A total of 34 participants were recruited, Two-thirds of whom remained in the study for the full study period. Both groups received 44 messages over 21 days. Message engagement was high, with most participants reading the daily messages (88.2% in the intervention group and 82.4% in the control group). The intervention was acceptable and helpful in supporting smoking reduction or cessation. Abstinence from all tobacco products was 20.6%, with a slightly higher rate in the intervention group (23.5%) than in the control group (17.6%). Cigarette abstinence was 35.3% in the intervention group and 23.5% in the control group, while waterpipe abstinence was much higher but equal in both groups (76.5%). Among those who continued smoking, modest reductions in cigarette and waterpipe consumption were reported in both groups. Conclusions: This Islamic faith-based intervention, delivered via WhatsApp messaging, was feasible and highly acceptable, showing promising effects on smoking cessation and reduction. However, these findings require verification in a larger, fully powered effectiveness trial. Clinical Trial: Australian and New Zealand Clinical Trials Registry

Background: Mobile health (mHealth) applications hold significant potential for improving healthcare, yet their adoption in developing countries like Egypt remains low. While most research focuses on patient acceptance, physicians' adoption is crucial for success. This study investigates the factors influencing Egyptian physicians' acceptance of the AFib mHealth app for managing Atrial Fibrillation, a common and serious heart condition. Objective: The primary objective was to identify the key factors affecting Egyptian physicians' behavioral intention and actual use of the AFib mobile application, using the Extended Unified Theory of Acceptance and Use of Technology (UTAUT2) as a theoretical framework. Methods: A cross-sectional online survey was distributed via convenience sampling to 35 cardiologists in Alexandria, Egypt. The survey measured their perceptions based on four key variables: Perceived Usefulness, Perceived Ease of Use, Social Influence, and Trust, and their link to Behavioral Intention and Actual Use. Data were analyzed using SPSS to perform descriptive statistics and test five research hypotheses. Results: Descriptive results showed high scores for Perceived Ease of Use (4.07), Perceived Usefulness (4.04), and Behavioral Intention (4.11). Trust (3.44) and Social Influence (3.33) received more moderate scores. Hypothesis testing revealed that Perceived Usefulness and Trust were the only factors with a statistically significant positive effect on Behavioral Intention. Surprisingly, Perceived Ease of Use and Social Influence did not significantly influence intention. Finally, a strong, significant link was confirmed between Behavioral Intention and Actual Use. Conclusions: The study concludes that for Egyptian physicians, the decision to adopt the AFib app is driven primarily by its perceived clinical utility and their trust in its reliability and security, not merely its ease of use or peer influence. Therefore, to enhance mHealth adoption, developers and policymakers should focus on demonstrating tangible benefits to patient care and ensuring robust data security and accuracy. These findings provide a valuable guide for implementing mHealth solutions in Egypt and similar developing contexts.

Background: Migraine is a common and disabling neurological disorder characterized by recurrent headaches and associated symptoms that significantly affect quality of life. Conventional physiotherapy plays a supportive role in migraine management; however, it may not adequately address central sensitization and altered pain modulation. Non-invasive neuromodulation techniques such as transcutaneous auricular vagal nerve stimulation (ta-VNS) and transcutaneous supraorbital nerve stimulation (t-SNS) have shown potential in modulating central pain pathways and reducing migraine burden. Objective: The primary objective of this study is to evaluate and compare the effectiveness of ta-VNS and t-SNS, each combined with conventional physiotherapy, in reducing pain intensity and migraine frequency, incidence in individuals with migraine. Secondary objectives include assessing their effects on migraine disability, neck disability, and cervical range of motion. Methods: This randomized controlled trial will include individuals clinically diagnosed with migraine. Participants will be randomly allocated into two groups: Group A will receive ta-VNS along with conventional physiotherapy, and Group B will receive t-SNS along with conventional physiotherapy. Both interventions will be administered for a defined treatment period. Outcome measures will be recorded at baseline, immediately post-intervention, and during follow-up periods to evaluate short- and long-term effects. Results: It is anticipated that both ta-VNS and t-SNS, when combined with conventional physiotherapy, will lead to significant improvements in pain intensity, migraine frequency, and functional outcomes. One neuromodulation technique may demonstrate superior or more sustained benefits over the other. Conclusions: This study is expected to provide comparative evidence on the effectiveness of ta-VNS and t-SNS as adjuncts to conventional physiotherapy in migraine management. The findings may support the inclusion of targeted non-invasive neuromodulation techniques in physiotherapy-based treatment protocols for migraine.

Background: Vessels encapsulating tumor clusters (VETC) are a distinct vascular pattern associated with aggressive behavior and poor prognosis in hepatocellular carcinoma (HCC). Preoperative identification of VETC is crucial for treatment planning but currently relies on invasive pathological examination. Radiomics-based artificial intelligence (AI) offers a potential noninvasive solution, yet evidence regarding its diagnostic and prognostic accuracy remains synthesized. Objective: We aimed to systematically evaluate the diagnostic performance and prognostic value of radiomics-based AI models for noninvasively predicting VETC status in patients with HCC. Methods: We systematically searched PubMed, Embase, Web of Science, and the Cochrane Library for studies published up to July 11, 2025. Studies developing or validating AI models using medical imaging (contrast-enhanced MRI [CEMRI], contrast-enhanced CT [CECT], contrast-enhanced ultrasound [CEUS], or [18F]FDG PET/CT) to predict pathologically confirmed VETC status in HCC patients were included. Study quality was assessed using the PROBAST+AI tool. Diagnostic accuracy (sensitivity, specificity, AUC) and prognostic value for early recurrence (hazard ratio [HR]) were pooled using random-effects models. Results: Fourteen studies involving 729 patients in internal and 581 in external validation cohorts were analyzed. AI models based on CEMRI demonstrated the highest diagnostic accuracy, with a pooled AUC of 0.87 (95% CI 0.84-0.90), sensitivity of 0.82 (95% CI 0.75-0.88), and specificity of 0.77 (95% CI 0.71-0.82). Models using other modalities (CECT, PET/CT, CEUS) showed moderate to good performance. Prognostically, HCC patients classified as VETC-positive by AI had a significantly higher risk of early recurrence (pooled HR 2.34, 95% CI 1.93-2.84). Conclusions: Radiomics-based AI models, particularly those using CEMRI, are promising for the noninvasive prediction of VETC and offer valuable prognostic stratification for early recurrence risk in HCC. However, significant heterogeneity and the retrospective nature of current studies limit the strength of evidence. Prospective, multicenter validation is required to confirm clinical utility.

Background: Baseline data from our survey of 527 self-referred users of the mental health chat- and voice bot Clare® indicate high psychological distress and barriers to accessing face-to-face care strong working alliance was established within 3–5 days (Working Alliance Inventory-Short Report, M = 3.76, SD = .72). The feasibility of sustained engagement and therapeutic bonding with Clare® in real-world use remains underexplored. Objective: This exploratory feasibility study evaluated engagement patterns, sustained therapeutic bonding, and preliminary mental health outcomes during 4- and 8-week use of the LLM-enabled voice and text chatbot Clare®. Methods: A single-group pre-post feasibility study was conducted with the English-speaking general population that self-referred and interacted with the voice- and chatbot Clare® for 4 weeks (n=53) or 8 weeks (n=21). Usage patterns, modes of engagement (hybrid, text-only, call-only), message volume, and call duration were examined. Users were further assessed for working alliance and changes in loneliness, depression, anxiety, distress, and life satisfaction at baseline, week 4 (t1), and week 8 (t2). Results: A total of 53 participants (73.6% women) engaged with the Clare® over 4 weeks (sample 1) and 21 participants (71.4% women) completed all assessments (sample 2), with both samples showing comparable demographic profiles. At baseline, participants reported moderate depression and anxiety, elevated social anxiety and high loneliness. Initial engagement peaked in the first week, with participants initiating an average of 1.77 calls and sending 10.02 messages, before declining steadily. On average participants initiated an average of 3.34 calls, sent 23.65 messages, and spent a total of 8.07 minutes in voice calls in 4 weeks. A comparable pattern was observed in the 8-week completer sample (n = 21). Working alliance increased over time, rising from 2.91 (SD 0.88) at baseline to 3.21 (SD 1.17) at mid-assessment and 3.34 (SD 1.03) at post-assessment (t3). There was no significant association with engagement intensity. Higher baseline distress was associated with fewer messages and lower alliance. Higher depressive symptoms were linked to fewer early calls and lower overall call frequency. Modest improvements were observed across loneliness, depression, anxiety, and distress. This was a feasibility study with substantial attrition and results should be interpreted with caution. Conclusions: Clare® appears feasible and acceptable for short-term community use, with early and stable bonding and preliminary signals of emotional and mental-health improvement. Declining engagement over time and the weak association between communication volume and alliance highlight the need for technology improvement and individualized symptom-oriented design strategies that support sustained and meaningful interaction.

Background: Child-centered care (CCC) is standard practice in pediatrics, emphasizing the child as an individual with rights while acknowledging the child's role within the family. A key aspect of CCC is the involvement of the child in health care decisions alongside parents and professionals. Although this is a right recognized by the United Nations Convention on the Rights of the Child (UNCRC) it may not always be applied in practice. Objective: The aim of this study is to explore the preferences of 3- to 5-year-old children for participation in health care from both the child's perspective as well as the child perspective, i.e., to ask their parents and health professionals about their understanding of children's preferences. Methods: Preferences were studied using Q-methodology, comparing responses from twelve children, fourteen parents, and twelve health professionals who ranked twenty-five statements. Factor analysis identified shared perspectives on participation preferences. Children’s rankings were also analyzed separately for comparison. Results: Three perspectives presenting different preferences were identified: direct communication between the child and healthcare professionals; understanding and shared decision-making; and responsive and child-led participation. A separate analysis of children’s rankings resulted in three perspectives: included in and setting their own terms for participation; small choices, meaningful outcomes; and trust through familiarity and shared decision-making. Conclusions: This study suggests that children value shared decision-making and situational control but prefer to leave major decisions to adults. It affirms that pre-school-aged children can meaningfully participate in healthcare when given age-appropriate choices, support, and tools. Children’s perspectives must be acknowledged directly rather than adults assuming their views. The findings support child-centered care (CCC) principles and reinforce the UNCRC mandate to respect children’s views regarding all issues relevant to them.

Background: The incidence of type 2 diabetes (T2D) continues to increase, and the lack of individualized therapy strategies hinders patient engagement with and commitment to a healthy lifestyle. The PROTEIN project aimed to facilitate users to choose healthy living, thereby improving their metabolism and T2D management. Objective: To assess the efficacy of a personalized mobile application to achieve a 5% time in range (TIR) improvement over a 12-week intervention in adults with prediabetes or T2DM. Methods: We conducted a randomized controlled trial (RCT) with 21 individuals with T2D or prediabetes who used a continuous glucose monitoring (CGM) system and the PROTEIN mobile application (PROTEIN app) for personalized meals and exercise recommendations based on their glucose levels and physical activity. Results: The TIR of the participants increased (p<0.05; from 71.8% ± 27.3% to 76.0% ± 28.1%) with individual use of the PROTEIN app but did not achieve a 5% improvement overall. Glycated hemoglobin, fasting blood glucose, and body weight did not fluctuate throughout the 12-week intervention. The dropout rate was high and the average duration of use of the PROTEIN app was 42 days (range 5 to 84). Conclusions: Our results showed an improvement in TIR with the use of the PROTEIN-app. Integrating wearables and automated personalization for wellbeing is an innovative approach that must keep pace with the accelerated development of ever-evolving technologies.

Background: Refugees commonly encounter barriers when accessing and navigating healthcare. While many educational interventions have been implemented to improve health literacy, the evidence is scattered. This emphases the need for a consolidation and synthesis of educational interventions. Objective: The purpose of this scoping review is to map and critically synthesise healthcare-related educational interventions designed for refugee populations. Specifically, it examines (1) the knowledge themes and topics of the healthcare educational interventions reported, (2) the pedagogical approaches, delivery formats, and educational tools employed and 3) the evaluation strategies and outcomes reported. Methods: A scoping search was conducted in four major databases (PubMed, CINAHL, EMBASE, and ERIC) for studies published between 2018 and 2024 that implemented and assessed a health or health-education intervention for refugee populations using the Joanna Briggs Institute (JBI) approach. Results: Forty-two studies satisfied the inclusion criteria. A wide range of health-related themes were identified but Diseases and Conditions, Mental Health, and Nutrition were identified as the most common knowledge themes across the included interventions reflecting refugee needs. Interventions used a variety of delivery methods, such as in-person, online, and mixed formats, although fully online interventions occurred less frequently in the studies explored. Didactic, lecture-style approaches were mainly adopted and applied across many interventions, however interactive and peer-led models were reported in some studies. Different studies varied in how they involved refugees and community members in the design and delivery of educational interventions. Approximately, one-third of the interventions actively included refugees in the design and development of the interventions. Outcomes of the educational interventions explored, were mainly measured in terms of knowledge gain, with fewer studies assessing behavioural change, health outcomes, or long-term impact. Where behavioural and health outcomes were reported, results were mixed. Finally, no relationship between educational approaches and outcomes could be conclusively discerned. Conclusions: Overall, this review provides a practical evidence basis for researchers, policymakers, and practitioners seeking to design and implement educational initiatives that improve health literacy and healthcare integration for refugee populations.

Background: The Swiss Personalized Health Network facilitates the interoperability and secure sharing of health-related data for research in Switzerland, in line with the FAIR principles. Since medical datasets can be highly sensitive, access is often governed by complex legal and regulatory requirements. Enabling researchers to discover, understand, and evaluate datasets through rich, well-structured metadata is therefore essential to support informed decisions about data suitability and reuse. Objective: This study describes the design and functionality of the SPHN Metadata Catalog and its role in supporting the discovery, exploration, and reuse assessment of health-related datasets. Methods: The SPHN Metadata Catalog is a FAIR Data Point-compliant infrastructure that provides rich, structured metadata in both human and machine-readable form. Dataset descriptions are based on HealthDCAT, ensuring a standardized representation of health data catalogs. Beyond the descriptive metadata typically offered by other catalogs, the SPHN Metadata Catalog includes extensive dataset-level statistics expressed using the Vocabulary of Interlinked Datasets. An interactive visualization component further enables users to explore graph-based schemas and datasets, including entities, attributes, relationships, and their relative abundances. Results: The SPHN Metadata Catalog enables users to explore the semantic structure of graph schemas and statistics of datasets prior to requesting access. Researchers can examine data structures, relationships, attributes, and the abundances of individual data elements. This functionality supports feasibility assessments and informed evaluations of dataset suitability and reuse conditions. Conclusions: By combining HealthDCAT-based descriptions with rich statistical metadata and interactive exploration capabilities, the SPHN Metadata Catalog enhances dataset discoverability and supports FAIR-compliant data reuse. As a key component of Switzerland’s health data research infrastructure, the SPHN Metadata Catalog provides a foundation for future interoperability initiatives, including potential alignment with emerging frameworks such as the European Health Data Space.

Background: Clinical Temporal Relation Extraction (CTRE) is essential for reconstructing patient timelines from unstructured Electronic Health Records (EHRs). However, the linguistic complexity of clinical notes and the high cost of expert annotation impede the development of large-scale training corpora. While Large Language Models (LLMs) have transformed general Natural Language Processing, their application to CTRE remains underexplored. Objective: This study aims to determine the optimal adaptation strategy for CTRE by conducting a comprehensive benchmarking of LLM architectures and fine-tuning methodologies in both data-rich and limited-data regimes. Methods: We evaluated four LLMs representing two distinct architectures: Transformer Encoders (GatorTron-Base, GatorTron-Large) and Transformer Decoders (LLaMA 3.1-8B, MeLLaMA-13B). We compared four adaptation strategies: (1) Standard Fine-Tuning, (2) Hard-Prompting, (3) Soft-Prompting, and (4) Low-Rank Adaptation (LoRA). Experiments were conducted on the 2012 i2b2 CTRE benchmark in both full-supervision and 1-shot scenarios. Results: We achieved results that exceed the current state-of-the-art (SOTA) on the 2012 i2b2 dataset. Comparative analysis reveals that hard-prompting consistently yields superior efficacy compared to standard fine-tuning. Regarding Parameter-Efficient Fine-Tuning (PEFT) strategies, Low-Rank Adaptation (LoRA) targeting query and value layers emerged as the optimal configuration. Conversely, soft-prompting demonstrated suboptimal performance, likely due to constraints on representational capacity. Architecturally, we observed a performance dichotomy based on data availability: Encoder-based models (GatorTron) exhibited superior stability and accuracy in few-shot scenarios, whereas Decoder-based models (LLaMA 3.1, MeLLaMA) demonstrated dominant performance in data-rich regimes. Conclusions: This study provides a rigorous roadmap for adapting LLMs to clinical extraction tasks. Based on our empirical findings, we recommend hard-prompting to maximize predictive accuracy and identify specific LoRA configurations (targeting query and value layers) as the preferred approach when computational efficiency is paramount. Furthermore, our findings suggest that while generative Decoders excel with abundant data, domain-specific Encoders remain the robust choice for few-shot clinical applications.

Background: Gamification has been increasingly integrated into mobile health (mHealth) applications to enhance user engagement and support mental health outcomes. However, empirical evidence explaining how gamified mHealth experiences contribute to users’ psychological well-being remains limited, particularly with respect to the underlying psychological mechanisms. Objective: This study aimed to examine the relationship between gamified mHealth experiences and psychological well-being and to investigate the mediating role of positive psychological capital (PsyCap) in this relationship. Methods: A cross-sectional survey was conducted among users of gamified mHealth applications. Gamified experience, PsyCap (hope, self-efficacy, resilience, and optimism), and psychological well-being were measured using validated scales. Structural equation modeling was employed to test the hypothesized mediation model. Results: Data from 483 active users of mobile health applications were analyzed. Gamification affordances (GA) were positively associated with psychological well-being (PWB) (β = 0.54, P < .001) and positive psychological capital (β = 0.61, P < .001). Positive psychological capital was also positively related to psychological well-being (β = 0.54, P < .001). Bootstrapping analysis (5,000 resamples) indicated a significant indirect effect of GA on psychological well-being via positive psychological capital (indirect effect = 0.32; 95% CI 0.21–0.43), supporting partial mediation. Conclusions: This study highlights positive psychological capital as a key psychological mechanism linking gamified mHealth experiences to psychological well-being. The findings extend gamification research beyond engagement-focused outcomes and underscore the importance of designing mHealth interventions that support psychological empowerment and long-term well-being.

Background: Non-Small Cell Lung Cancer (NSCLC) remains the leading cause of cancer-related mortality worldwide. The identification and prioritization of molecular biomarkers involved in NSCLC pathogenesis are essential for advancing early diagnostic strategies and optimizing therapeutic interventions. Objective: This study aimed to utilize genomic network approaches and bioinformatics tools to prioritize clinically relevant biomarkers associated with NSCLC. Methods: Non-Small Cell Lung Cancer (NSCLC) remains the leading cause of cancer-related mortality worldwide. The identification and prioritization of molecular biomarkers involved in NSCLC pathogenesis are essential for advancing early diagnostic strategies and optimizing therapeutic interventions. This study aimed to utilize genomic network approaches and bioinformatics tools to prioritize clinically relevant biomarkers associated with NSCLC. Results: Data integration from three major genomic repositories DisGeNET, GWAS Catalog, and cBioPortal 1,317 NSCLC associated genes. Subsequent analyses included gene ontology enrichment, pathway enrichment, and protein–protein interaction (PPI) network construction. Network-based prioritization identified ten key hub genes: TP53, MYC, PTEN, CTNNB1, ACBT, STAT3, CCND1, AKT1, ESR1, and HIP1A, with
TP53, MYC, PTEN, CTNNB1 as the most prominent biomarkers according to CytoHubba scoring. Conclusions: This study presents a genomic network-based framework for identifying and prioritizing potential NSCLC biomarkers, offering critical insights into the molecular underpinnings of NSCLC pathogenesis.

Background: The global increase in the older adult population has led to a rising prevalence of cognitive impairment and dementia. Non-pharmacological interventions, particularly engaging activities like tabletop games, are crucial for cognitive maintenance and well-being. However, existing commercial cognitive assistive tools often fail due to two main issues: a disconnect from the cultural and life experiences of the users, and an overly high cognitive load that hinders engagement and efficacy in clinical settings. There is an urgent need for an intervention tool designed specifically for this population, integrating principles of cultural relevance and neural adaptability to maximize therapeutic outcomes. Objective: This study aimed to develop a user experience-oriented, modular card-based assistive tool as an effective non-pharmacological intervention for older adults with mild cognitive impairment and dementia. The primary goal was to construct a robust cognitive intervention framework that enhances user motivation and improves neural feedback efficiency by integrating both cultural adaptability and neuroplasticity principles. Methods: The research utilized a multi-stage mixed-methods approach, grounded in User Experience Innovation Design methodology. The study combined literature analysis, structured expert interviews, ethnographic participatory observation, and preliminary prototype testing. The work was conducted across long-term care centers, dementia care centers, and day care centers in a county in southern Taiwan. Seventeen participants, including healthcare professionals, caregivers, administrative staff, and healthy older adults, were involved in the data collection and co-creation process to ensure the practical and cultural relevance of the design. Results: Results: The findings confirmed that cultural symbol misalignment and excessive cognitive demand were the main barriers to using current assistive tools, accounting for approximately 73% of reported usage difficulties. The newly developed tool, through the embedding of localized cultural contexts and a dynamic staged design, significantly enhanced participant motivation. Crucially, preliminary testing indicated effective enhancement of neural feedback efficiency. Conclusions: The study successfully designed and validated a modular cognitive assistive tool that overcomes common barriers by prioritizing cultural embedding and dynamic cognitive pacing. We propose a "Cultural-Cognitive Embedding Model" as a guiding framework, emphasizing that assistive tool design must integrate local life history and dynamically adjust cognitive difficulty to effectively promote neuroplasticity and sustained engagement in dementia care.

Background: Sleep is a core component of psychiatric assessment, yet inpatient monitoring typically relies on brief observational checks that are subjective, variable, and sometimes disruptive. Wearable devices offer a means of capturing continuous, objective sleep and activity data without disturbing patients. Although digital health technologies are increasingly used in psychiatric research, little is known about how wearable-derived data can be integrated into routine inpatient workflows or used meaningfully by clinicians. Objective: This implementation aimed to evaluate the feasibility, usability, and workflow integration of a wearable-derived sleep and activity reporting system within an adult psychiatric inpatient unit. Methods: The implementation unfolded in two phases on a 21-bed inpatient unit at a psychiatric hospital in Massachusetts, USA. Patients were offered a wrist-worn GENEActiv actigraphy device upon admission. Raw accelerometry data were processed using the DPSleep pipeline to derive daily sleep and activity metrics for patients participating in the implementation. Sleep and activity reports combining graphical summaries and natural language summaries of sleep, activity, and medication data were iteratively refined and delivered to psychiatrists providing patient care. Semi-structured qualitative interviews were conducted with clinicians and unit staff to gather feedback on the sleep and activity report prototype and discuss barriers and facilitators to implementation. Interview data were coded and analyzed by a team of two. Results: During the first phase of the implementation, 155 patients were admitted, 88 (56% of admits) were offered a device, and 68 (77% of admits offered a device) accepted. Sleep and activity reports were generated for 42 patients (62% of patients wearing a device) during this phase. During the second phase of the implementation, automation reduced report generation time from approximately five days to under 24 hours. Only one of the three psychiatrists assigned to the unit regularly used the reports in routine care. Reports were most useful for reconciling discrepancies between patient and nursing sleep estimates and for supporting clinical conversations about sleep patterns and medication adherence between clinician and patient. Clinicians who had not yet used the reports expressed conceptual interest but emphasized the need for integration in the electronic medical record, reliably available “last-night” sleep data, and simplified design. Barriers included challenges in the speed, reliability, and clarity of data; variable staff buy-in; and disconnects between the research and clinical teams running the implementation. Conclusions: Wearable-derived sleep and activity data reporting is feasible in inpatient psychiatry and offers clinically meaningful insights, particularly when patient and staff sleep reports conflict. Sustainable use is more likely with near-instantaneous data transfer, electronic medical record integration, and shared implementation ownership across staff levels. Clinical Trial: Not applicable

Background: Advance in healthcare technology is essential to bridge persistent gaps in achieving sustainable healthcare delivery in emerging economics. At the frontline of innovation, the rapid integration of artificial intelligence (AI) into primary healthcare offers a transformative potential to revolutionize diagnostic accuracy, personalized treatments, and optimized clinical workflows. However, this rapid adoption also introduces critical challenges regarding patient safety risks, ethical concerns, regulatory inconsistencies, infrastructural deficiencies, and inequities, encounted for in emerging economies. Objective: Review the current applications of AI in primary healthcare, evaluate both the transformative opportunities and the systemic risks they pose with emphasis on the principles of technological equity, and stakeholder-centred design. Methods: This study used a structured literature review for articles published in Scopus electronic database between 2020 and 2025 with search keywords was used. Results: The study identified 43 research articles on the expectation of AI in primary healthcare, identified risks and opportunities for Human-Centered and Ethical AI Strategies for Health Technology Design, AI-Health technology innovation with patient safety, security and digital decolonization in emerging economies, enable contextual investigation in AI health technology design, Availability of updated health data. Conclusions: The analysis presents evidence-based observation to balance technological innovation with the imperative to protect the patient well-being and promote equitable access. The findings of this study underscore the necessity of research and development, interdisciplinary collaboration, regulatory frameworks, and continuous assessment of healthcare technology to ensure AI integration advances in healthcare without exacerbating existing disparities.

Background: In heart failure patients, cardiac rehabilitation(CR) is recommended. However, center-based cardiac rehabilitation (CBCR) experiences low referral rates, accessibility barriers, and economic constraints, leading to low usage rate. Mobile health offers a potential solution to these limitations through the remote delivery of home-based cardiac rehabilitation (HBCR). Objective: The objective of this systematic review and meta-analysis was to evaluate the comparative effectiveness of mobile health (mHealth) HBCR interventions versus usual care and CBCR among heart failure patients. Methods: Four electronic databases (MEDLINE, PubMed, Cochrane Library, and Embase) were searched from inception to October 27, 2025, without restrictions on language or publication type. Eligible studies comprised randomized controlled trials enrolling heart failure patients aged 18 years and older, with comparisons between mHealth HBCR interventions and usual care or CBCR. The primary outcome of interest was aerobic exercise capacity, as assessed by peak oxygen consumption (VO2 peak) or the 6-minute walk test (6MWT). Secondary outcomes included health-related quality of life. This review was registered in PROSPERO (CRD420251162078). Results: A total of 4,540 records were identified, and 62 underwent full-text assessment. Seven randomized controlled trials that met the inclusion criteria were included in the systematic review, encompassing 1,307 patients with heart failure. Intervention durations ranged from 8 to 12 weeks, and exercise frequencies varied from daily to five times per week. A random-effects meta-analysis demonstrated that mHealth HBCR significantly improved VO2 peak(SMD 0.36, 95% CI 0.11 to 0.62; p = 0.01) and the SF-36 score (SMD 0.16, 95% CI 0.03 to 0.28; p = 0.01). Compared with usual care, mHealth HBCR was associated with significant improvements in the 6MWD(SMD 0.81, 95% CI 0.23 to 1.39; p = 0.01) and MLHFQ score (SMD -0.57, 95% CI -0.98 to -0.17; p < 0.01). No significant differences were observed between mHealth HBCR and CBCR. Conclusions: MHealth HBCR significantly enhances aerobic exercise capacity and quality of life among heart failure patients. However, further large-scale randomized controlled trials are warranted to elucidate the impact of mHealth HBCR on all-cause mortality, major adverse cardiovascular events, and rehospitalization rates among heart failure patients.

Background: Prolonged residence in post-disaster container settlements may adversely affect respiratory health through environmental, functional, and psychosocial pathways. However, population-based evidence incorporating objective pulmonary and functional indicators remains limited. Objective: This study aimed to quantify pulmonary function, dyspnea, fatigue-related functional capacity, and health-related quality of life among adults living in container settlements after the 2023 Kahramanmaraş earthquakes and to identify key sociodemographic and functional determinants. Methods: This cross-sectional field study included 360 adults (mean age 41.2±9.3 years; 53.6% female) residing in three container settlements in Malatya, Türkiye. Pulmonary function (FVC, FEV₁, FEV₁/FVC) was assessed using spirometry according to ATS/ERS standards. Dyspnea (mMRC), sleep quality (PSQI), muscle strength (handgrip dynamometry), and quality of life (SF-36) were evaluated. Group comparisons, correlation analyses, and multiple linear regression models were applied.
Results
Median FVC and FEV₁ were 2.85 L (IQR 2.30–3.40) and 2.32 L (IQR 1.85–2.85), respectively, while the mean FEV₁/FVC ratio remained within normal limits (80.1%±6.2). Significant differences in FVC and FEV₁ were observed by sex (p<.001; r=0.82) and employment status (p<.001; r=0.56). Handgrip strength showed strong positive correlations with FVC (r=0.74) and FEV₁ (r=0.77, both p<.001), whereas sleep quality demonstrated small but significant associations (p=.021; ε²=0.031). In multivariable analysis, age, sex, body mass index, employment status, and handgrip strength independently predicted FVC (adjusted R²=0.61; p<.001). Results: Respiratory impairment among adults living in post-disaster container settlements primarily reflects reduced lung volume and functional capacity rather than obstructive airway disease. Functional and social determinants, particularly muscle strength and employment status, play a central role, underscoring the need for integrated post-disaster respiratory surveillance and rehabilitation strategies. Conclusions: Respiratory impairment among adults living in post-disaster container settlements primarily reflects reduced lung volume and functional capacity rather than obstructive airway disease. Functional and social determinants, particularly muscle strength and employment status, play a central role, underscoring the need for integrated post-disaster respiratory surveillance and rehabilitation strategies.

Background: This study aims to assess the robustness of randomized control trials (RCTs) in the dental field by analyzing the fragility index (FI). The FI is a statistical measure defined as the smallest number of event changes needed to convert statistical significance (P< 0.05), of a binary outcome, to a not significant result. Previous studies have found that the results of many RCTs in medical disciplines are very fragile. However, there is limited literature examining the robustness of trials in dentistry. Objective: The primary objective of this study is to evaluate the fragility of RCTs in top dental journals using the FI. The secondary objective is to explore factors associated with fragility. Methods: We will identify RCTs from five high-impact dental journals namely, Periodontology 2000, International Journal of Oral Science, Journal of Clinical Periodontology, Journal of Dental Research, and Journal of Dentistry published between January 2019 and December 2024 reporting at least one primary binary outcome. We will estimate the FI and factors associated with FI will be assessed using regression analysis. Results: Screening and data extraction began in August 2025 and are expected to conclude by December 2025. Data analysis will be conducted in January 2026, and we anticipate submitting the results for publication by March–April 2026. Conclusions: Dental practitioners rely on RCTs to guide patient care and treatment planning. Assessing the FI of trials allows us to determine the robustness of their results. By evaluating fragility, dental practitioners and policymakers can make more informed decisions on evidence based care and identify areas for further research.

Background: Large language models (LLMs) such as ChatGPT and Google Gemini have demonstrated promising capabilities in medical reasoning and clinical decision support. However, their comparative performance against human specialists in critical care scenarios, particularly acid-base disorder interpretation and sepsis management, remains inadequately characterized. Objective: This study aimed to compare the diagnostic and therapeutic decision-making performance of advanced AI models (ChatGPT-4 and Google Gemini), a consensus-based ensemble AI approach, and human medical specialists in acid-base disorder interpretation and sepsis management scenarios using validated clinical vignettes. Methods: A total of 45 clinical case vignettes (20 acid-base disorder cases and 25 sepsis management cases) were developed by an expert panel. Cases were independently evaluated by 20 human specialists (10 emergency medicine physicians and 10 anesthesiologists), ChatGPT-4, Google Gemini, and a simple majority-voting ensemble model. Blinded evaluation was ensured throughout. Performance metrics included diagnostic accuracy, treatment recommendation appropriateness, and Surviving Sepsis Campaign (SSC) bundle compliance rates. Results: For acid-base disorder interpretation, the ensemble AI model achieved the highest overall accuracy (86.0%), followed by anesthesiologists (84.5%), ChatGPT-4 (83.7%), emergency physicians (83.2%), and Google Gemini (79.5%). In simple metabolic and respiratory disorders, AI models demonstrated comparable or superior performance to human experts (>90% accuracy). However, human specialists outperformed individual AI models in mixed acid-base disorders (humans: 75.5% vs ChatGPT: 68.5%, Gemini: 65.3%, P<.05). For sepsis management, SSC hour-1 bundle compliance was highest in the ensemble model (95.8%), followed by ChatGPT-4 (94.2%), human experts (91.5%), and Gemini (89.7%). Conclusions: Advanced LLMs demonstrate comparable performance to human specialists in straightforward acid-base and sepsis scenarios, with ensemble approaches showing potential for improved accuracy. However, human expertise remains superior in complex, atypical presentations requiring nuanced clinical judgment. These findings are limited to text-based simulations and require validation in real-world clinical environments.

Background: ostoperative pain following total knee arthroplasty (TKA) is a significant challenge for both physicians and patients, adversely impacting patients' quality of life and the rehabilitation of joint function post-surgery. Exploring efficient and safe therapy approaches to alleviate pain and enhance joint function recovery is of paramount importance. Transcutaneous electrical acupoint stimulation (TEAS) demonstrates significant efficacy in alleviating postoperative pain. Nevertheless, there is a paucity of studies regarding its application following total knee arthroplasty. Objective: This study is to assess the effectiveness of TEAS in conjunction with multimodal analgesia for reducing postoperative pain and enhancing the quality of joint function rehabilitation following TKA. The impact of TEAS in conjunction with multimodal analgesia on opioid dosage and associated adverse responses, as well as the mechanism by which it enhances postoperative analgesic efficacy, was investigated. Methods: This article outlines a randomized controlled clinical trial that was blinded solely to evaluators. 154 participants were randomly allocated to an experimental group and a control group, with 77 cases in each group. This experiment will consist of a baseline phase, a 1-week treatment period, and a 12-week follow-up period. The control group patients who received TKA were administered the normal multimodal analgesic protocol. Patients in the experimental group received TEAS for 30 minutes, twice daily, from postoperative days 1 to 7, alongside normal multimodal analgesic treatment. The primary outcomes included Visual Analog Scale (VAS) at 3 and 7 days after surgery and the Western Ontario and McMaster Universities (WOMAC) score at 28 days after surgery. Secondary outcomes included VAS score at baseline and 1 day after surgery, WOMAC score at baseline, 1 week, 2 weeks and 12 weeks after surgery, and Short-Form 12-Item Health Survey (SF-12) at baseline, 4 weeks and 12 weeks after surgery. Other exploratory outcome measures included: knee pain threshold, Laser speckle imaging (LSI), quadriceps femoris motor unit stability index, knee skin temperature with infrared thermography (IRT), and plasma β-endorphin (β-EP) concentration. The knee pain threshold was evaluated at baseline, 1 day, 3 days, 7 days after surgery, and the plasma β-EP concentration was evaluated at baseline, 1 day, 7 days, 14 days after surgery. Other parameters were evaluated at baseline and 2 weeks after surgery. The use of postoperative analgesics was also recorded. Results: Recruitment for this clinical study began in July 2022, and we enrolled the first subject on July 21, 2022. As of January 1, 2025, all 154 planned participants had been enrolled. The study data are currently being collated and analyzed, and the results are expected to be completed and reported in the first quarter of 2026. Conclusions: The results of this study can provide a basis for TEAS to relieve pain after TKA and accelerate joint function recovery. Clinical Trial: Chictr.org.cn identifier: ChiCTR2200063897.

The healthcare digital transformation is gaining increasing notoriety, despite the observed challenges in its implementation. The envisioned benefits together with the growing need for better healthcare are motivating academia, organizations, regulatory agencies, and governments to develop more effective digital healthcare solutions. Through extensive debates among the authors and supported by a narrative literature review, this paper discusses how digital transformation is being conducted in the healthcare sector. Our discussion relies on the concepts from the sociotechnical systems theory categorizing it according to three social (people, culture, and goals) and three technical (processes/procedures, infrastructure, and technology) dimensions. Overall, we argue that both social and technical dimensions present elements that have been either encouraging or discouraging the progress of healthcare digital transformation. The identification of current trends on such (on- and off-track) elements allowed the formulation of propositions for future testing and validation. This approach can help the establishment of better government policies, foster private initiatives, and shift regulatory guidelines to support a successful digital transformation in health systems. Lastly, from a research perspective, we outline some opportunities for further interdisciplinary investigation in the field, promoting advances in the understanding of healthcare digital transformation.

Background: Internet search engines serve as primary gateways for cancer information, yet the commercialization of health content within organic search results remains understudied. While covert promotional content—such as native advertising and stealth marketing—has been documented in various contexts, systematic comparisons across structurally divergent search platforms are lacking. Objective: This study examined the prevalence, distribution, and information quality characteristics of covert promotional cancer-related content across Naver and Google, South Korea's two dominant search engines, which have fundamentally different platform architectures. Methods: A two-phase cross-sectional content analysis was conducted. Phase 1 employed natural language processing to identify 33 cancer-related keywords from 1,400 preliminary posts. Phase 2 systematically collected 5,848 posts in October 2023, yielding 919 unique posts (598 from Naver and 321 from Google) that covered seven major cancer types, representing over 70% of Korean cancer incidence. Two trained coders analyzed promotional status, intensity, institutional sources, and information quality indicators (citation practices, information depth, and source attribution), with inter-coder reliability exceeding κ=.80. Chi-square tests examined the associations between platform and cancer type. Results: Covert promotional content appeared in 48.6% (447/919) of analyzed posts, with significantly higher prevalence on Google (54.2%, 174/321) than Naver (45.7%, 273/598; χ²₁=5.78, p=.016). Platform differences were pronounced: Naver promotional posts predominantly originated from blogs (96.0%, 262/273) and exhibited full promotional intensity (52.1%, 126/242), while Google posts primarily came from hospital websites (81.0%, 141/174) with simple institutional identification (57.8%, 52/90). Institutional source distribution varied significantly by platform (χ²₅=215.714, P<.001): traditional medicine institutions dominated Naver (99.2%, 119/120), whereas university-affiliated hospitals predominated on Google (85.0%, 96/113). Information quality differed substantially: indirect citation was more common on Google (81.6%, 142/174) than Naver (58.6%, 160/273; χ²₁=25.653, P<.001), while comparative informational depth was higher on Google (55.7%, 97/174) versus Naver (19.4%, 53/273; χ²₂=64.683, P<.001). Conclusions: Covert promotional cancer content is pervasive in Korean search results, with platform architecture systematically shaping promotional patterns, institutional sources, and information quality rather than reflecting deliberate marketing strategies. These findings underscore the need for platform-sensitive regulation and enhanced digital health literacy to protect vulnerable cancer information seekers from commercial exploitation embedded within ostensibly neutral search environments.

Background: The gut microbiota plays a crucial role in infant nutrition through its effects on energy metabolism, nutrient absorption, and immune regulation. However, evidence from Indonesian infants remains limited. Objective: This study aimed to examine the association between gut microbiota composition and underweight among infants in coastal areas of Central Sulawesi, Indonesia. Methods: A follow-up observational study was conducted among 88 six-month-old infants in coasta areas of Banggai, Central Sulawesi. Maternal and infant characteristics were collected through structured interviews and anthropometric assessments. Weight-for-age Z-scores (WAZ) were calculated based on WHO growth standards, and underweight was defined as WAZ < −2 SD. Fecal samples were analyzed by quantitative PCR to quantify the bacterial genera Bifidobacterium, Lactobacillus, Bacteroides, Clostridium, and Escherichia coli. Group differences were assessed using chi-square, Mann–Whitney U, and Wilcoxon signed-rank tests. Associations between bacterial abundance and WAZ were evaluated using multivariable linear regression, adjusted for relevant maternal, environmental, and infant factors. Results: The mean WAZ was −0.47 ± 1.09, and 8.0 % of infants were classified as underweight. Beneficial genera (Bifidobacterium, Lactobacillus) predominated over opportunistic bacteria (Wilcoxon signed-rank, p = 0.0017). Higher Clostridium abundance was inversely associated with WAZ (unadjusted β = −0.094, 95 % CI –0.173 to –0.015; p = 0.021; adjusted β = −0.089, 95 % CI –0.166 to –0.014; p = 0.030). No significant associations were observed for other bacterial genera. Conclusions: An increased abundance of Clostridium was independently associated with underweight status among infants in coastal Central Sulawesi. These findings highlight the potential role of gut microbiota imbalance in early growth faltering and support the need for longitudinal studies to clarify causal mechanisms and inform microbiota-targeted nutritional interventions in coastal Indonesian populations.

Background: Outdoor secondhand smoke (SHS) remains a public health concern, particularly around designated outdoor smoking areas where non-smokers may pass through or linger nearby. While previous studies have quantified outdoor SHS concentrations, fewer have examined the number of people potentially exposed in real-world settings. Estimating exposure opportunity at the population level requires methods that are feasible, scalable, and minimally intrusive. Objective: This study aimed to evaluate the feasibility of using passive Wi-Fi packet sensing, calibrated with brief on-site observation, to quantify the number of smokers and passersby within a plausible SHS exposure range at a public outdoor smoking area in Japan. Methods: We conducted a formative field study at a designated outdoor smoking area of the Asia Pacific Trade Center (ATC), Osaka, Japan. A passive Wi-Fi packet sensor was installed adjacent to the smoking area, collecting timestamps, anonymized device identifiers (hashed MAC addresses), organizationally unique identifiers (OUIs), and received signal strength indicator (RSSI) values from October 13 to 29, 2023. On October 28, a high-traffic event day, a 30-minute manual count (15:00–15:30) of smokers and passersby was conducted within a 25-m radius to calibrate sensor-derived estimates. Records outside business hours were excluded, and devices transmitting outside business hours were treated as fixed devices and removed. Detected signals were aggregated into presence episodes, screened by dwell time, and classified as likely smokers or passersby using empirically derived RSSI thresholds. Calibration ratios from the observation window were applied to estimate hourly and daily counts during business hours. Results: During the 30-minute observation period, 14 smokers and 207 passersby were visually counted within the 25-m radius. On the same day, sensor logs yielded 659 eligible presence episodes during business hours. Applying classification rules and calibration ratios, we estimated that 262 smokers and 3,907 passersby were present within the plausible SHS exposure range over the course of the day. Temporal patterns indicated bimodal peaks in smoker presence and a midday peak in passerby traffic, corresponding to event-related footfall. Conclusions: This formative study demonstrates the feasibility of combining passive Wi-Fi packet sensing with brief manual validation to quantify population-level exposure opportunities to outdoor SHS in a real-world setting. The approach offers a low-cost and privacy-preserving method for assessing outdoor SHS exposure and may inform the design, placement, and management of smoking areas in public spaces. Further multi-site studies are warranted to refine exposure estimation and support evidence-based tobacco control strategies.

Background: Disparities in access to dermatologic care in medically underserved and rural communities within Northeast Ohio are reflective of national trends. MetroHealth’s teledermoscopy tool, Snapshot, is intended to streamline triage for potentially cancerous skin lesions. However, its utilization patterns and ability to expand access to care have not been studied. Objective: This study aimed to identify demographic and geographic trends in Snapshot utilization and assess its capacity to reach populations that may lack access to dermatologic care. Methods: County-level data on dermatologist density was extracted from records obtained from the American Academy of Dermatology (AAD). Spearman correlations were used to examine the relationship between Snapshot utilization and dermatologist density at the county level. A retrospective analysis of all Snapshot encounters from 2018 to 2025 was performed to identify demographic characteristics and clinical outcomes of this patient population. A ZIP code-level analysis was performed to identify areas with the greatest Snapshot encounters. Results: A total of 1,274 patients used Snapshot between 2018 and 2025, with 2,016 total Snapshot encounters. At the county level, dermatologist density was strongly positively correlated with Snapshot utilization (Pearson r=0.968, P<0.001; Spearman ρ=0.709, P=.028). A ZIP code level analysis demonstrated that the highest rates of utilization clustered around ZIP codes containing MetroHealth clinics offering Snapshot due to its walk-in design. However, 58% of Snapshot users were new patients with no prior dermatology encounters, indicating its potential role as an entry point into specialty care. Conclusions: Snapshot utilization appears to be strongly driven by dermatologist density geographic proximity to a MetroHealth clinic, suggesting that it is not bridging geographical gaps in access to dermatological care but is likely acting as a triage tool for patients with potentially cancerous skin lesions. However, the high proportion of new users suggests that it is acting as an entry point for patients who were not previously connected to dermatological care. Further work comparing Snapshot users with the broader MetroHealth dermatology population is needed to elucidate the characteristics of those who are currently benefiting from Snapshot and identify the ways it can be implemented to reach those who remain disconnected from care.

Background: Environmental factors account for 23% of global deaths and 25% of chronic diseases. In France, the 4th National Health and Environment Plan prioritizes training health professionals in environmental health. Endocrine disruptors (EDCs) are chemical substances that interfere with hormonal systems, contributing to a range of health effects. In 2024, the Primary Care Environment and Health (PCEH) program at the University of Montpellier–Nimes introduced an innovative e-learning module on EDCs for first-year family medicine residents. Objective: To evaluate the impact of the PCEH e-learning module on participants’ satisfaction, knowledge, and self-reported behaviors regarding EDCs in household environments. Methods: This monocentric, matched before–after cohort study included all first-year family medicine residents. The module, developed collaboratively by clinicians and educators, integrated interactive images, AI-generated virtual rooms, short educational videos, games, and flashcards. Participants were assessed using pre- and post-training questionnaires, administered immediately before and after the training. These questionnaires evaluated satisfaction (using a 5-Likert scale), knowledge (with binary yes/no questions), and behaviors (using a 5-point Likert scale). Statistical analyses used McNemar’s test for qualitative variables and paired t-tests for quantitative variables (p < .05). Results: Of 148 eligible residents, 78 (52.7%) completed both assessments over a 17-day period. Overall satisfaction was high (mean 4.0/5, SD 0.9), with positive ratings for the e-learning format (4.1/5, SD 1.0) and duration (4.2/5, SD 1.0). Knowledge improved significantly, with a mean 56% increase in correct identification of EDCs across all substances (p < .001). Self-reported behaviors improved by 2.13 points (95% CI 1.71–2.56) on the 5-point scale (p < .001), exceeding gains reported in previous PCEH modules. Secondary outcomes showed high post-training identification of at-risk populations and exposure locations, though recognition of some substances (e.g., alkylphenols, phenoxyethanol) remained lower. Conclusions: This innovative e-learning module significantly improved residents’ knowledge and preventive behaviors related to EDCs. Findings support integration into curricula and potential replication in other health professions.

Background: The COVID-19 pandemic disrupted the delivery of occupational therapy (OT) services in-person on a global scale, accelerating the adoption of telehealth. During this time, there was a surge of OT focussed research on the use of telehealth. Synthesising this literature can be helpful to inform routine practice and to prepare for future disruptions to in-person care, including natural disasters, severe weather, and pandemics. Objective: This scoping review maps the literature on telehealth in OT during COVID-19, focusing on setting, study design, participants, clinical fields, modalities, interventions, outcomes, benefits, barriers, and facilitators. Methods: Using Arksey and O’Malley’s framework and Joanna Briggs Institute guidelines, we searched seven databases and Google Scholar for peer-reviewed articles. Eligibility criteria included: English and French papers reporting on telehealth-delivered OT services during COVID-19, across all ages, conditions, settings, and participant groups. Results: From 4,810 records screened, 43 articles were included. Most articles originated from high-income economies and were small in scale (mean=136; median=15). Most were descriptive (e.g., cross-sectional surveys, qualitative studies, and experiential reports). Participant groups were diverse, including OTs, clients, caregivers, and others (e.g., teachers). Telehealth in OT was most reported in pediatric neurodevelopmental and mental health fields, followed by adult mental health. Most articles described synchronous telehealth and the remaining a mixed approach. Only 40% reported on measurable outcomes, with most of these demonstrating statistically significant results. Reported benefits included improved accessibility, personalization, continuity of care, safety in terms of infection prevention, family engagement, and social support. Perceived barriers included technology access and literacy, lack of physical presence, limitations of the home environment, client and caregiver factors, and organizational challenges. Facilitators included home and intervention adaptations, digital skills and training, caregiver involvement, communication strategies, and organizational and system-level support. Conclusions: Telehealth helps to increase access to OT; however, therapists face barriers in using this approach especially for some interventions and populations. More research is needed on how best to implement telehealth across different populations and contexts. Clinical Trial: n.a.

Background: The growing complexity of colorectal cancer (CRC) management requires advanced tools for integrating multimodal data and clinical knowledge. Large language models (LLMs) offer a promising approach to address these challenges through sophisticated natural language processing and reasoning capabilities.
Objective: This systematic review evaluates the current applications, performance, and practical implications of LLMs across the continuum of CRC care, from screening to treatment decision support. Objective: This systematic review evaluates the current applications, performance, and practical implications of LLMs across the continuum of CRC care, from screening to treatment decision support. Methods: We searched six databases (PubMed, Embase, Web of Science, Scopus, CINAHL, Cochrane) up to November 1, 2025, following PRISMA guidelines. Included studies were original research investigating LLM applications specific to CRC, with extractable outcome data. Quality was assessed using QUADAS-2, PROBAST, and ROBINS-I tools by two independent reviewers. Results: Following the screening of 1,261 records, 34 studies met the inclusion criteria, all published between 2023 and 2025. The synthesis highlighted the utility of LLMs in automating data extraction from clinical texts, supporting patient education, aiding diagnostic processes, and assisting in clinical decision-making, with growing evidence of their emerging visual interpretation and multimodal capacities. The effectiveness of these models was significantly influenced by prompt design, which varied from basic zero-shot queries to specialized fine-tuning techniques. While the overall methodological quality of the included studies was deemed adequate, assessments identified recurring concerns regarding insufficient control of biases and inadequate reporting on data security measures. Conclusions: LLMs demonstrate tangible potential to augment CRC care, particularly in structuring unstructured data and providing clinical decision support. However, translating this potential into practice requires solutions for domain adaptation, multimodal integration, and rigorous prospective validation to ensure reliability and safety in real-world settings.

Background: The effectiveness of ST-elevation myocardial infarction (STEMI) treatment is highly time-dependent, and the information barrier between prehospital and in-hospital settings remains a key factor leading to treatment delays. Existing digital coordination tools either have a single function or lack long-term real-world evidence support, making it difficult to meet clinical needs. This study adopts a self-developed prehospital chest pain alert app (hereafter referred to as the App) by Fengxian District Medical Emergency Center. Mediated through a WeChat-based chest pain center group, the App enables prehospital information synchronization, real-time alerts, multidisciplinary coordination, and feedback on treatment outcome parameters to form a closed-loop communication model, providing a solution to break the information barrier. Objective: To evaluate the impact of the App-mediated prehospital-in-hospital coordination model on treatment delays (e.g., time from first ECG to catheterization laboratory preactivation, door-to-wire time) and clinical outcomes (e.g., 30-day major adverse cardiovascular events, 1-year and 4-year all-cause mortality) in STEMI patients, and to assess its generalizability in high-risk subgroups. Methods: This is a single-center retrospective cohort study. STEMI patients admitted to Fengxian District Central Hospital from January 1, 2019, to December 31, 2024, will be enrolled and categorized into three groups: baseline group (January 1, 2019-December 31, 2020, without App use), intervention group (January 1, 2021-December 31, 2024, with App-mediated coordination), and concurrent control group (STEMI patients who came to the hospital independently without calling an ambulance or were transported by ambulance but not reported via the App during the same period). The primary outcome is door-to-wire time (D2W). Secondary outcomes include other treatment delay indicators, clinical prognosis, and App operational efficiency. We will use propensity score matching (PSM) to control for baseline confounding, segmented linear regression to analyze intervention trend effects, and subgroup analysis to assess generalizability in high-risk populations. Results: This study is based on four-year real-world data from the Department of Cardiology and STEMI database of Fengxian District Central Hospital. Baseline data and intervention-related data are derived from the hospital’s electronic medical record system and App backend logs. A total sample size of ≥944 is expected. Data extraction and statistical analysis are scheduled from January to April 2026. Results will focus on the App-mediated model’s effect on reducing treatment delays and improving clinical outcomes. Conclusions: Using four-year real-world data combined with PSM and interrupted time series analysis, this study will provide high-quality evidence for the App-mediated coordination model, which is expected to optimize the regional STEMI care system and offer references for the application of digital health technologies in acute coronary syndrome treatment.

Background: Background: Type 2 diabetes (T2D) is one of the most prevalent non-communicable diseases, requiring ongoing lifestyle change and continuous glucose management to support medication use, diet, and physical activity. Traditional self-monitoring of blood glucose can be burdensome, particularly with frequent finger pricks. As continuous glucose monitoring (CGM) becomes more affordable and widely available, it offers clear benefits, including improved glucose awareness, behavioural adjustments, and reduced anxiety. However, challenges persist, such as cost, pain from sensor insertion, skin reactions to adhesives, and privacy concerns. In the UK, patient perceptions of CGM among people with T2D, both users and non-users, remain under-explored, limiting understanding of factors that influence adoption and sustained use, and the support needed to promote adherence. To the authors’ knowledge, this is the first UK-based study to explore the perspectives of both CGM users and non-users with T2D using a large, nationally representative sample. The identified benefits and challenges emerging from this study provide valuable insights to inform research, clinical practice, and policy aimed at supporting the equitable adoption and sustained use of CGM in the UK. Objective: Objectives: This qualitative study aims to explore how adults with type two diabetes (T2D) perceived the benefits and challenges of using continuous glucose monitoring (CGM), including both current users and non-users. Methods: Methods: This study employed a cross-sectional, online survey using YouGov’s nationally representative panel to explore experiences of continuous glucose monitoring (CGM) among adults with type 2 diabetes (T2D) in the UK. A total of 531 participants were recruited in December 2024. Thematic analysis of responses to two open-ended questions identified key perceived benefits and challenges associated with CGM use. Results: Results: A total of 531 adults with type 2 diabetes (T2D) completed the YouGov online survey. Over half were male (55.9%) and aged 65+ years (53%). Two-thirds (65%) had lived with T2D for more than five years, and 9.5% had ever used a CGM.
Nearly half of participants (49%) provided free-text responses on CGM benefits and 33% on challenges. Thematic analysis identified five key benefit themes: (i) practicality and user-friendliness, (ii) better understanding of lifestyle impacts on glucose levels, (iii) improved self-management, (iv) enhanced safety, and (v)improved data sharing with healthcare providers. The main challenges identified included (i) limited access, (ii) usability and technological issues, (iii) overreliance on passive monitoring, (iv) emotional burden, and (v) data-related matters. Conclusions: Conclusions: Continuous glucose monitoring (CGM) was perceived by adults with T2D as a practical and empowering tool that enhances understanding, safety and collaboration with healthcare providers. However, access barriers, usability challenges and emotional and data-related burdens remain significant obstacles to the equitable adoption of these technologies. Addressing these challenges through improved affordability, digital literacy support, and tailored clinical guidance may help promote sustained and inclusive CGM use in routine diabetes care.

Background: Human papillomavirus (HPV) remains the principal cause of cervical cancer, yet population-level awareness and knowledge in many Nigerian settings remain limited. Understanding the patterns and predictors of HPV awareness and knowledge is essential for strengthening Nigeria’s HPV vaccination rollout and reducing preventable cervical cancer morbidity. Objective: To describe respondents’ demographic characteristics; assess levels of awareness and knowledge of HPV, cervical cancer, and the HPV vaccine; examine associations between sociodemographic variables and awareness/knowledge; and identify independent predictors of HPV awareness and knowledge. Methods: A community-based cross-sectional survey was conducted among 238 caregivers of girls aged 9-14 years in Port Harcourt Local Government Area. Data on demographics, HPV awareness, knowledge indicators, and information sources were collected using a structured questionnaire. Descriptive statistics, chi-square tests, and multivariable logistic regression were used to assess associations and predictors. Statistical significance was set at p < 0.05. Results: Respondents showed wide demographic diversity across age, religion, education, occupation, and income. Overall awareness of HPV was low (45.4%), and knowledge was predominantly poor (78.6%). Misconceptions were common, with many attributing HPV to poor hygiene or skin infections. Only 39.8% correctly identified sexual contact as the mode of transmission, and knowledge of vaccine dosage was inconsistent. Informal channels, religious institutions, social media, and family networks were the primary sources of information, whereas health workers accounted for only 8.3%. Most sociodemographic factors showed no significant association with awareness or knowledge, indicating widespread deficits across groups. Occupation was the only variable significantly associated with awareness (p = 0.011). Logistic regression showed higher odds of awareness among respondents aged 26-36 years (OR 2.26, p = 0.039) and lower odds among those practicing Traditional religion (OR 0.41, p = 0.033). Civil/public servants showed reduced odds of awareness (OR 0.44, p = 0.048). Conclusions: HPV awareness and knowledge are markedly low and broadly distributed across demographic groups. Widespread misconceptions reflect structural failures in health communication. Strengthen community-based and health worker-led HPV education; embed messaging within religious and social structures; and implement targeted, culturally adapted communication strategies to improve vaccine uptake. Significance Statement: Addressing pervasive knowledge gaps is vital for achieving effective HPV vaccination coverage and reducing cervical cancer burden in Nigeria.

Introduction
Acute leukemia poses a significant health burden globally, necessitating a deeper understanding of its etiological factors. This study investigates the potential link between blood groups, Rh factor, and the incidence of acute leukemia to enhance knowledge and guide personalized treatment strategies.
Methods
A cross-sectional analytical study was conducted at Imam Khomeini Hospital in Urmia from 2012 to 2018, including patients with acute leukemia. Data on blood groups, Rh factor, and demographic variables were collected and analyzed using SPSS software. Statistical tests were employed to determine associations between blood groups and leukemia risk.
Results
The study found no significant relationship between ABO blood groups and acute leukemia, consistent with previous research. However, differences in Rh factor distribution were observed between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) patients, warranting further investigation.
Discussion
The complexity of leukemia etiology is highlighted by the multifactorial nature of the disease, where genetic, environmental, and possibly epigenetic factors interact. Future research should focus on larger sample sizes and diverse populations to elucidate the intricate mechanisms underlying leukemia susceptibility.
Conclusion
While ABO blood groups may not significantly impact acute leukemia risk, variations in Rh factor distribution among leukemia subtypes suggest a need for continued exploration. Comprehensive studies considering diverse factors are essential to unravel the complexities of leukemia development.

Introduction
Immune thrombocytopenic purpura (ITP) is an acquired thrombocytopenia syndrome characterized by platelet destruction due to antiplatelet antibodies. Corticosteroids are the first-line treatment for adult patients with ITP. This study compares the effects of high-dose dexamethasone versus prednisolone in ITP treatment.
Materials and Methods
This open-label clinical trial involved patients over 18 years diagnosed with ITP (based on ASH criteria) who had not received prior treatment. Participants were randomly assigned (1:1) to receive high-dose dexamethasone (HD-DXM) or prednisolone (PDN). The dexamethasone group received 40 mg intravenously for 4 consecutive days, while the PDN group received 1 mg/kg oral prednisolone for 4 weeks. Daily complete blood counts were obtained to assess treatment response, defined as a platelet count above 30,000/μL.
Results
A total of 36 patients were evaluated, with 18 in each treatment group. Patients receiving dexamethasone showed significantly reduced hospitalization duration and faster time to reach platelet counts above 30,000/μL (P=0.01 and P=0.002, respectively).
Conclusion
High-dose dexamethasone significantly decreases the time to initial response and hospitalization duration in ITP patients compared to prednisolone.

Classical evolutionary theory, notably Riedl’s concept of canalization, suggests that human lifespan is constrained by deeply entrenched developmental architectures, implying that aging is an immutable biological reality. However, rapid advancements in artificial intelligence (AI) from 2023 to 2025 have begun to challenge this pessimism. This viewpoint synthesizes recent developments to argue that AI is reframing aging from a biological mystery into a tractable engineering challenge. We examine two primary frontiers: the use of autonomous AI agents and generative models to discover geroprotective interventions, including the identification of compounds like ouabain via large-scale omics re-analysis; and the maturation of multi-modal “aging clocks” that utilize deep learning to enable precision diagnostics and personalized healthspan optimization. While acknowledging significant limitations regarding safety, translation from animal models, and the risks of commercial hype, we conclude that the integration of AI with mechanistic geroscience offers a plausible pathway toward a proactive, engineering-based approach to human longevity.

Biobanks are recognised as lucrative health research resources due to their extensive and in-depth data availability, which allows researchers to draw correlations between various genetic, lifestyle, and health information and future disease incidence. As prospective data sources collect genetic and lifestyle information for several hundred thousand participants across various age categories, biobanks are important datasets in designing novel healthcare approaches. Within the realm of cardiometabolic ageing, which refers to the age related decline in the function of cardiovascular and metabolic systems, the conceptualisation of a systems medicine-based approach known as P4 (Predictive, Preventive, Personalised, Participatory) medicine has provided an interesting framework to tackle these metabolic illnesses in tandem with digital longevity tools that serve as vessels to deliver interventions across large populations. Therefore, this review aims to critically discuss how digital longevity informed by biobank data is vital in improving risk prediction, with a focus on cardiometabolic ageing.

Background: Globally, digital health interventions (DHIs) enhance HIV care through technology, especially among women living with HIV (WLHIV), who face unique Challenges that affect their treatment. This study assessed the feasibility of integrating DHIs into HIV care in Kisumu by examining their acceptability among WLHIV and identifying factors that influence their intention to use these tools. Objective: (1) To determine the feasibility of integrating digital health interventions into care for
women living with HIV in Kisumu.
(2) To identify factors that influence the adoption of Digital health interventions. Methods: A cross-sectional survey based on the Unified Theory of Acceptance and Use of Technology
2 (UTAUT2) was administered to evaluate the acceptability of SMS, teleconsultations, online support groups, and health applications. Summary statistics quantified acceptability, multivariate regression models examined associations between UTAUT2 constructs and behavioral intention, and Analysis of Variance identified sociodemographic predictors. Results: A total of 385 WLHIV (mean age 35·8 years) participated. Behavioral intention to use all four DHIs was high, with more than 80% rating their willingness at ≥4 on a five-point scale. Performance expectancy, hedonic motivation, habit, and price value were significant predictors of intention (p < 0·05). Higher education level was strongly associated with increased intention (p < 0·001), while older age was associated with reduced intention Conclusions: WLHIV in Kisumu demonstrated a strong willingness to adopt digital health tools in their routine care. The intention to use DHIs was primarily influenced by perceived usefulness, affordability, enjoyment, and familiarity with similar technologies. These results support the integration of digital health solutions into HIV care for women in this setting.

Background: The COVID-19 pandemic presented an unparalleled opportunity for telemedicine implementation, shortening adoption timelines and creating significant opportunities for observational research. Prior evidence is predominantly derived from small feasibility studies with limited comparative efficacy data and inadequate attention to implementation challenges and equity considerations. Objective: To synthesize methodologies, findings, and innovations from observational telemedicine studies conducted during the pandemic and identify critical research gaps. Methods: Narrative synthesis of 25 peer-reviewed observational studies (2020–2021) examining telemedicine across 11 clinical specialties, encompassing 119,016 patient contacts across multiple international settings. Studies employed prospective cohort designs, retrospective analyses, cross-sectional surveys, and mixed-methods approaches. Results: Telemedicine demonstrated clinical efficacy for chronic disease management with objective monitoring data, particularly in pediatric diabetes and cardiac device follow-up. However, substantial technology-acceptance discrepancies emerged—user satisfaction exceeded actual data capture reliability. Cross-sectional analyses unveiled systemic racial bias in satisfaction ratings and socioeconomic disparities in access. Innovations, including real-time locating systems, large-scale observational platforms, ambispective designs, and mixed-methods integration, have advanced methodological rigor. Persistent obstacles encompass selection bias, unmeasured confounding, outcome heterogeneity precluding meta-analysis, and temporal confounding. Conclusions: Observational pandemic-era telemedicine research substantiates selective clinical applications while exposing technology reliability limitations, persistent inequities, and methodological constraints on causal inference. Critical gaps include the absence of long-term outcome evaluation, economic analyses, diagnostic accuracy assessment, and equity-focused intervention research. Future advancement requires quasi-experimental designs, standardized outcome measures, explicit equity integration, and implementation science evidence for sustainable post-pandemic integration.

Background: Safe and reliable access to clean water remains a fundamental determinant of public health and sustainable development. In many rapidly urbanizing Nigerian communities, dependence on self-sourced groundwater and inadequate waste management systems continues to compromise water quality and expose residents to preventable diseases. This study investigated the status of water supply, quality, and associated health outcomes in Uselu Community, Benin City, to provide evidence-based insights for policy and intervention. Objective: The study aimed to (1) assess the primary sources of water available to residents, (2) evaluate household water-storage and treatment practices, and (3) examine the public-health implications of inadequate water access and sanitation behaviour in the community. Methods: A descriptive cross-sectional survey was conducted among 100 adult residents of Uselu Community selected through random sampling. Data were collected using structured questionnaires covering socio-demographics, water sources, treatment habits, sanitation practices, and self-reported waterborne diseases. Field observations complemented survey data, and results were presented as frequencies and percentages. Descriptive and inferential statistics were used to analyze trends, and findings were compared against national and international WASH benchmarks. Results: Findings revealed that 56% of respondents relied on boreholes as their main water source, while only 31% had access to public pipe-borne supply. Although 89% regularly washed their storage containers, fewer than half (43%) treated water by boiling or filtration, and only 17% practiced chlorination. About 32% reported disposing of waste near water sources, increasing contamination risks. The most common illnesses were typhoid fever (47%) and cholera (30%), with over half (55%) of respondents experiencing recurrent water shortages. These results indicate persistent infrastructural inadequacies, limited treatment adoption, and significant exposure to waterborne diseases. Conclusions: The study highlights critical water-supply and quality challenges in Uselu Community, driven by poor infrastructure, weak waste management, and inconsistent household treatment practices. Ensuring safe water access requires coordinated interventions combining infrastructural expansion, community hygiene education, and sustainable groundwater management. Strengthen municipal water systems, establish periodic water-quality monitoring, enforce sanitation regulations, and promote affordable household treatment technologies through continuous public-health education and community engagement. This study demonstrates that unsafe water and poor sanitation behaviours are central drivers of disease in Uselu Community. By translating evidence into actionable interventions, the research provides a model for improving public health, environmental sustainability, and water security in similar peri-urban settings.

For decades, global guidance for sedentary behaviour and sleep has primarily been informed by studies that relied on self-report questionnaires to assess behaviours. However, it is widely recognised that self-reported data suffer from numerous limitations, including recall and social desirability biases, as well as poor validity and precision. The Prospective Physical Activity, Sitting and Sleep consortium (ProPASS) is a large international collaboration of cohort studies with research-grade wearables data designed to address these challenges. The ProPASS consortium looks to advance our understanding of the associations of free-living physical activity, posture (sitting, standing), and sleep with major health and non-communicable disease outcomes. In this editorial, we provide an overview of the first ProPASS scientific outputs including its growth in recent years; key advancements towards unified wearables methodologies; the ProPASS data resources, and how these will be made available to the global research community. To assist future analogous initiatives, we also share the key challenges ProPASS has encountered and discuss mitigation strategies.

Universities are critical engines of knowledge creation and societal transformation; however, many African institutions, particularly in Nigeria, struggle to cultivate mature and sustainable research cultures. This paper develops a conceptual framework for strengthening university research management systems, highlighting leadership and governance as catalysts for academic excellence, innovation, and societal relevance. Using a descriptive-analytical and comparative synthesis of international policy frameworks (UNESCO, OECD) and African higher-education reports (AAU, ARUA, NUC, and TETFund), the study integrates global best practices with contextual realities in low-resource environments. The proposed Research Leadership and Impact Framework (RLIF) outlines four interrelated components: leadership and vision, governance and systems, capacity and infrastructure, and research culture and societal impact, which collectively enable institutional transformation. Comparative indicators, such as Nigeria’s Gross Expenditure on Research and Development (GERD) of 0.22% versus South Africa’s 0.83%, illustrate the strategic significance of leadership and governance reform in closing performance gaps. The framework contributes a theoretically grounded and context-sensitive model for embedding evidence-based management, accountability, and inclusivity within African universities. Ultimately, the paper argues that building resilient research systems requires not only financial investment but visionary leadership capable of aligning academic missions with societal priorities and the Sustainable Development Goals (SDGs).

Background: Approximately 27% of United States adults live with a disability, yet they face persistent disparities in health outcomes and access to care. The systematic collection of disability status and accommodation needs data in electronic health records (EHRs) can support more equitable access to care, help ensure that patients with disabilities receive appropriate, person-centered care, and bolster efforts to monitor and address health disparities for people with disabilities. However, data collection remains limited in the health care setting. Objective: This qualitative study aimed to examine current practices for collecting, documenting, and exchanging disability-related data in EHRs. This study identifies the current state of disability-related data collection by health care organizations; describes how these data are used by health care organizations and researchers; presents challenges to data collection; and offers opportunities to advance the standardized collection and use of disability-related data. Methods: A qualitative, two-pronged approach was employed, consisting of a literature scan and 13 key informant interviews with stakeholders from health systems, research institutions, and policymaking and advocacy organizations. Data were analyzed using a structured abstraction matrix to identify themes related to data collection practices, use cases, challenges, and opportunities to improve standardization and interoperability. Results: We identified three use cases for collecting, documenting, and exchanging disability-related data: (1) preparing for patient visits, (2) improving care quality, (3) facilitating care transitions, and (4) advancing equity research. However, findings from the literature scan and key informant interviews revealed that most health care organizations do not routinely collect disability status or accommodation needs data. Among those that do, they employ varied and non-standardized approaches, hindering the ability of health care organizations to provide legally mandated accommodations and deliver equitable, patient-centered care. Conclusions: Conclusions: Standardized and systematic collection of disability status and accommodation needs data is critical to advancing health equity, improving care quality, and supporting patient-centered care for people with disabilities. The inclusion of “disability status” as a requirement for certified health information technology, including electronic health records (EHR), beginning in 2026 represents a critical step toward more standardized data collection. Efforts to strengthen data collection practices should include workflows for documenting a patient’s self-reported disability and requested accommodations, enhancing health information technology systems, engaging stakeholders across health care settings, and promoting adoption of national standards to ensure disability-related data are accurate, actionable, and interoperable.

India’s health system faces chronic resource gaps and inefficiencies. With public health
spending at only 1.84% of GDP and very low hospital bed densities (around 0.6 beds per 1000 population), simply adding beds is unaffordable and slow. A more efficient alternative is to improve utilisation: a real-time digital platform that tracks staffed bed availability can raise effective capacity and reduce inequity.
Early experiments – from Delhi’s COVID-19 bed portal to the bed-management system
in AIG Hospitals, Hyderabad – show substantially higher occupancy and throughput. International evidence also supports these results, confirming that real-time tracking
systems can deliver major efficiency gains.
This brief proposes piloting a national bed-tracking dashboard and shows it can yield
large gains for much lower cost and risk than new construction, with safeguards to address data accuracy, incentives and privacy. These promising results are tempered
by limited evidence from a small number of pilots and by systemic constraints such as
staff shortages, uneven digital readiness, and governance challenges that will require
independent evaluation and safeguards during scale up.

Deep learning-based medical image registration methods increasingly incorporate both architectural enhancements (affine transformations) and training objective improvements (regularization losses), yet their individual and combined contributions remain poorly understood. To quantify the individual and synergistic effects of affine components versus regularization losses on deformable medical image registration performance through systematic ablation analysis, we conducted a controlled ablation study using the OASIS brain MRI dataset comparing four model variants: baseline 3D U-Net with basic similarity losses, regularization-enhanced U-Net, affine-enhanced U-Net with basic losses, and fully enhanced model combining both components. Primary outcomes included registration accuracy metrics (mean squared error [MSE], normalized cross-correlation [NCC], structural similarity index [SSIM]), enhanced deformation quality analysis including Jacobian determinant preservation and anatomical plausibility scoring, and computational efficiency measures. Regularization enhancement alone achieved substantial performance improvements: 21.3% relative improvement in MSE (1.78% → 2.16%, P<.05) and 21.8% improvement in NCC (0.0555 → 0.0676), while dramatically reducing maximum deformation from 53.1 to 0.51 units (99.0% reduction) with negligible computational overhead (-0.06% inference time). Combined approaches achieved optimal performance with 25.8% relative MSE improvement (1.78% → 2.24%) and enhanced anatomical plausibility scores (0.596 → 0.930), at moderate computational cost (+9.8% inference time). Enhanced gradient correlation analysis revealed substantial improvements in structural preservation (0.742 → 0.980 for fully enhanced model). All enhanced variants achieved sub-voxel registration accuracy with anatomically plausible deformation constraints. Regularization losses provide the primary driver of performance improvements in medical image registration, offering both accuracy gains and dramatic deformation control enhancement with maintained computational efficiency. Architectural enhancements provide complementary benefits at acceptable computational cost. The dramatic improvement in deformation control (99% reduction in unrealistic deformations) addresses critical clinical deployment concerns while achieving superior registration accuracy.

Background: Urinary conditions impose a widespread burden on patients, caregivers, and healthcare systems. Emerging technologies, including wearable and remote devices, offer opportunities to improve diagnosis, monitoring, and care delivery. Yet, the perspectives of healthcare professionals, who are central to technology adoption, remain underexplored. Objective: This study aimed to explore healthcare professionals’ perceptions of urinary issues and examine their views on the opportunities and barriers associated with adopting health technologies for urinary care. Methods: An online survey of 256 healthcare professionals collected qualitative responses about urinary care and the role of technology. Data were analyzed using grounded theory methods, including open, axial, and selective coding, to develop an explanatory model grounded in providers’ narratives. Results: Analysis revealed four interconnected categories: Technology and Innovation in Patient Care, Patient-Centered and Integrated Care, Accessibility and Ethical Considerations, and Proactive and Preventative Urological Health Management. These categories were unified within the emergent Grounded Theory of Technology Negotiation in Urinary Care, which describes how professionals integrate new technologies through a negotiated process that balances enthusiasm for innovation with patient-centered values, systemic barriers, and preventative goals. Adoption occurs when innovations align with professional values, overcome structural constraints, and enhance holistic, sustainable care. Conclusions: Healthcare professionals approach the integration of urinary health technologies as an active negotiation rather than passive acceptance. This grounded theory underscores that successful adoption requires user-centered design, comprehensive training, supportive reimbursement structures, and preservation of meaningful patient engagement. Recognizing adoption as a negotiated process provides a framework for guiding sustainable technology integration in urinary care.

Background: Patients with rare diseases often face fragmented healthcare, limited access to specialists, and challenges in securely sharing their medical records across providers. Emerging technologies such as blockchain offer a decentralized and tamper-resistant framework for personal health records (PHRs), but their feasibility in low-resource settings remains largely unexplored Objective: This study aimed to evaluate the feasibility, usability, and patient perceptions of a blockchain-enabled PHR system tailored for rare disease patients in low-resource healthcare environments Methods: We conducted a mixed-methods pilot study involving 32 patients with rare genetic and metabolic disorders in Faisalabad, Pakistan. Participants were enrolled in a blockchain-based PHR platform that allowed secure storage and controlled sharing of medical data. Quantitative data on system usage, error rates, and access patterns were collected over a 12-week period. Semi-structured interviews and focus groups were used to explore patient and caregiver experiences, perceived benefits, and challenges. Thematic analysis was applied to qualitative data, while descriptive statistics summarized quantitative measures. Results: Patients and caregivers reported high levels of trust in the blockchain system (78% expressed greater confidence compared to hospital records). Key perceived benefits included improved data ownership, reduced dependency on fragmented paper records, and greater willingness to share information with providers. However, barriers included limited digital literacy, occasional connectivity issues, and the need for ongoing technical support. Quantitatively, 85% of enrolled participants successfully accessed and updated their records at least once, while 62% shared data with external providers. Thematic analysis revealed three major themes:
(1) empowerment through ownership
(2) digital divides as barriers to adoption
(3) the importance of community support in technology uptake Conclusions: Blockchain-enabled PHRs show promise for enhancing healthcare access, trust, and patient empowerment among rare disease populations in resource-constrained settings. Despite challenges related to usability and infrastructure, the pilot demonstrates potential for scaling such systems with targeted training and support. Further large-scale studies are needed to assess long-term sustainability and integration with existing health systems. Clinical Trial: not aplicable

Background: Long-standing intrapsychic conflicts often arise from apparently irreconcilable tensions, such as desire versus affection or autonomy versus dependence. Traditional approaches in psychotherapy describe defense mechanisms or splitting to cope with such conflicts. However, less attention has been given to creative integrative processes that may reconcile opposing tendencies. Objective: This paper introduces the concept of AI-facilitated symbolic juxtaposition, where generative models are used to create “digital chimeras”—hybrid symbolic constructions integrating objects of desire with affective attributes. We aim to provide a theoretical foundation, operational hypotheses, and clinical protocols for testing this novel framework. Methods: Drawing from psychoanalytic theory (Winnicott’s transitional objects), predictive processing, and neuroscience of the default mode and mentalizing networks, we propose a neuro-symbolic model for symbolic integration. We outline four testable hypotheses: (1) neural integration (DMN coherence), (2) symbolic flexibility, (3) enhancement of attachment security, and (4) accelerated therapeutic outcomes. Empirical validation methods include fMRI, EEG coherence, eye-tracking, attachment interviews, and cognitive flexibility tasks. We also present a clinical implementation protocol with AI-assisted symbolic generation, immersive VR/AR environments, and ethical safeguards. Results: As a conceptual and methodological paper, results are presented as expected outcomes. We anticipate that AI-facilitated chimera formation will (a) improve DMN connectivity, (b) enhance cognitive flexibility, (c) increase attachment security, and (d) reduce the number of sessions required for clinically significant change. Clinical protocols emphasize therapist training, patient safety, cultural adaptation, and preservation of therapeutic alliance. Conclusions: AI-facilitated symbolic juxtaposition represents a novel approach to psychotherapy, offering a scientifically grounded and clinically feasible method for resolving long-term intrapsychic conflicts. By combining neuro-symbolic AI, neuroscience, and psychotherapy theory, this framework contributes to the field of digital mental health and sets the stage for future empirical validation across cultural contexts.

This study examines the phenomenon of "sandbagging" in AI medical devices, where systems strategically underperform during evaluation to conceal dangerous capabilities that emerge post-deployment. Through systematic analysis of emerging literature on AI sandbagging behaviour, technical detection approaches, and regulatory structures in the EU, UK, and US, this research reveals critical gaps in current regulatory frameworks designed for traditional medical devices. Analysis shows sandbagging manifests through both developer-driven mechanisms (where engineers intentionally display safer capabilities for expedited deployment) and system-driven mechanisms (where AI systems autonomously underperform during evaluation phases). Research shows that both large frontier and smaller models exhibit sandbagging behaviours after prompting or fine-tuning while maintaining general performance benchmarks, with larger models demonstrating superior calibration capabilities. Current static regulatory approaches in the EU Medical Device Regulation and UK frameworks fail to detect sandbagging as they rely on documentation-based submissions without addressing AI's dynamic, generative nature. The US FDA's Total Product Lifecycle approach shows promise through algorithm change protocols and real-world performance monitoring, yet regulatory sandboxes remain underutilized. Healthcare provider liability becomes dangerously ambiguous when clinicians rely on systems with concealed capabilities, particularly given automation bias effects and black-box reasoning limitations. Traditional risk classifications focusing on direct bodily harm inadequately address AI's potential for deceptive behaviour, including "password-locked" models that reveal hidden capabilities when triggered. Technical detection solutions including attribution graph analysis and noise-based detection show promise but remain insufficient. Dynamic evaluation frameworks are essential, recommending mandatory regulatory sandboxes for real-world testing, continuous monitoring protocols, adversarial testing, and enhanced post-market surveillance.

Background: Mental health has become one of the most urgent global health issues of the twenty-first century. The World Health Organization (WHO) reports that over 970 million individuals globally were affected by a mental disorder in 2022, with depression and anxiety being the most common disorders. The strain of mental illness is heightened by restricted availability of qualified healthcare providers, stigma associated with mental health, and the growing need for accessible, affordable, and scalable solutions. These obstacles emphasize the immediate necessity for creative, tech-based approaches that can foster mental health among various communities. In recent times, artificial intelligence (AI) has demonstrated considerable promise in this area, especially with the creation of emotion detection systems and digital health solutions.
In spite of these improvements, a significant drawback remains: numerous AI-based mental health tools do not possess the required empathy and inclusiveness to effectively assist at-risk users. Although machine learning (ML) models are becoming more proficient at accurately identifying emotions through text, voice, and facial expressions, their incorporation into human–computer interaction (HCI) systems frequently overlooks crucial aspects of trust, empathy, and cultural awareness. This results in a divide between technological effectiveness and the human-focused care that mental health treatments require. In the absence of empathetic design, digital solutions may alienate users, decrease engagement, and diminish their possible clinical effectiveness.
Consequently, the research gap exists at the convergence of ML and HCI. Current research has mainly centered on enhancing the efficiency of emotion recognition algorithms, but considerably less emphasis has been placed on creating interfaces that promote inclusivity, establish trust, and guarantee that users feel truly understood and supported. This disparity is especially important in mental health, where emotional sensitivity and stigma require careful focus on user experience and ethical factors. Closing this gap necessitates a multidisciplinary strategy that integrates progress in affective computing with principles of empathetic design.
This research aligns directly with the United Nations Sustainable Development Goals (SDGs), particularly SDG 3, which emphasizes the promotion of good health and well-being, and SDG 16, which advocates for inclusive, just, and responsive institutions. By integrating robust ML techniques with empathetic HCI frameworks, the study contributes to the creation of digital mental health solutions that are not only technically sophisticated but also socially responsible and ethically grounded.
II. Related Work
A. AI in Mental Health
Artificial intelligence (AI) has been progressively examined as a way to enhance mental health assistance via scalable and accessible digital solutions. Chatbots like Woebot and Wysa have shown the ability of conversational agents to provide cognitive behavioral therapy (CBT) and various therapeutic methods via text interactions [1], [2]. Likewise, machine learning (ML) models aimed at emotion recognition have progressed notably, utilizing natural language processing (NLP) for sentiment evaluation [3], speech processing for emotion detection [4], and computer vision for recognizing facial expressions [5]. These advancements have allowed for systems that can identify stress, depression, and anxiety with promising degrees of precision. Nevertheless, although these AI tools show impressive technical skills, many still lack the capacity to offer emotionally intelligent and empathetic assistance, essential in mental health situations.
B. Health-focused HCI
Research in human computer interaction (HCI) has greatly enhanced the usability and acceptance of digital health systems. Research highlights that trust, empathy, and inclusivity hold significant importance in delicate areas like mental health [6]. Design methods focused on users have demonstrated that patients are more inclined to interact with tools that offer individualized feedback, culturally relevant material, and supportive emotional interfaces [7]. Additionally, multimodal interaction utilizing voice, gesture, and visual feedback has been shown to improve user experience and accessibility in healthcare technology [8]. In spite of these developments, there are limited studies that explicitly merge strong emotion recognition abilities with empathetic HCI frameworks, resulting in a disconnect between affective computing and inclusive design.
C. Ethical Considerations
The implementation of AI in mental health also brings significant ethical dilemmas. Concerns regarding bias in emotion recognition models have been extensively documented, especially when datasets lack representation from specific cultural or demographic groups [9]. Likewise, the privacy and security of sensitive mental health information continue to pose significant challenges, with potential risks of misuse or unauthorized sharing of personal data [10]. Transparency and explainability pose additional issues, as users frequently do not comprehend how AI models generate predictions, potentially diminishing trust and acceptance [11]. Principles of inclusive design are crucial to reduce these risks, making certain that AI systems cater to various populations justly and impartially.
D. Synthesis of Research Gaps
Although AI-based emotion recognition has made significant technical advancements, and HCI studies emphasize the need for empathy and inclusivity in healthcare technologies, the convergence of these two fields is still inadequately investigated. Many current studies either concentrate on enhancing algorithmic precision without adequately addressing user experience, or they highlight empathetic design while not utilizing advanced multimodal ML features. This results in a void in the literature where technically sound emotion recognition systems are absent from empathetic and trust-building HCI frameworks. To tackle this gap, interdisciplinary strategies that merge affective computing with human-centered design are needed to create digital mental health solutions that are both effective and ethically sound Objective: The present study aims to address this challenge by pursuing three interrelated objectives. First, it seeks to develop ML models capable of multimodal emotion recognition, drawing on textual, vocal, and facial cues to capture a holistic picture of user affective states. Second, it proposes to design empathetic, user-centered HCI interfaces that emphasize inclusivity, accessibility, and trust. Third, the study intends to evaluate the effectiveness of these systems in improving user trust, engagement, and perceived empathy in digital mental health support contexts. Methods: This research employs a multidisciplinary approach that combines machine learning (ML) methods for multimodal emotion identification with human–computer interaction (HCI) models aimed at promoting empathy, inclusivity, and trust. The methodological framework includes four essential elements: data gathering, model creation, HCI design, and assessment.
A. Data Collection
To aid in creating strong multimodal emotion recognition models, the research employs datasets that include three modalities: (i) text data obtained from online mental health forums, patient diaries, and anonymized chatbot conversations, (ii) voice recordings gathered from publicly accessible affective speech databases and ethically sanctioned user recordings, and (iii) facial expression images and videos obtained from recognized emotion recognition datasets. Every data collection procedure adheres to global privacy standards, such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA). Approval from the Institutional Review Board (IRB) and informed consent are secured when needed to guarantee the ethical management of sensitive data.
B. Machine Learning Models
The ML framework comprises specialized models for each modality, followed by multimodal fusion approaches.
1. Text Emotion Recognition: Transformer-based NLP architectures such as BERT, RoBERTa, and DistilBERT are employed to analyze sentiment and detect fine-grained emotional states from user-generated text.
2. Speech Emotion Recognition: Deep learning models such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), and wav2vec2.0 are implemented to extract acoustic and prosodic features for affective state classification.
3. Facial Emotion Recognition: Vision-based models including ResNet and EfficientNet are utilized for real-time detection of facial expressions associated with primary emotions (e.g., happiness, sadness, anger, fear).
4. Multimodal Fusion: Late fusion and attention-based architectures are applied to combine predictions from textual, vocal, and visual modalities, enabling more accurate and context-aware emotion recognition.
C. HCI Design Framework
The user interface is designed following empathetic and inclusive HCI principles.
1. Empathetic User Experience (UX): The design incorporates calming color schemes, adaptive conversational tone, and responsive interactions that convey empathy and emotional support.
2. Trust-Building Mechanisms: Explainable AI techniques (e.g., attention visualization, confidence scores) are integrated to enhance transparency. Feedback loops allow users to correct misclassifications, thereby increasing trust and personalization.
3. Inclusiveness: The system supports multilingual interaction, accessibility features for visually or hearing-impaired users, and culturally adaptive content presentation to ensure equitable usability across diverse populations.
D. Evaluation Metrics
The proposed system is evaluated across three dimensions: ML performance, HCI usability, and clinical impact.
1. ML Performance: Standard classification metrics including accuracy, F1-score, and area under the receiver operating characteristic curve (AUC-ROC) are used to assess model effectiveness in detecting emotions.
2. HCI Evaluation: Usability is measured through the System Usability Scale (SUS), while trust and engagement are assessed using structured surveys and qualitative interviews. Empathy perception is evaluated through user ratings and linguistic analysis of chatbot interactions.
3. Clinical Impact: Self-reported improvements in well-being, stress reduction, and emotional awareness are collected via validated psychological assessment scales to evaluate the potential therapeutic value of the system Results: IV. Results

V. Discussion
A. Performance of Models: Benchmarking Multimodal ML Systems
The proposed multimodal models were evaluated in comparison to unimodal baselines. As demonstrated in Table 4 and represented in Figure 2 (ROC curves), the multimodal fusion model outperformed the classifiers using only text (Accuracy = 84.5%, F1 = 0.83), speech (Accuracy = 80.2%, F1 = 0.81), and facial features (Accuracy = 78.6%, F1 = 0.79), achieving better results (Accuracy = 91.2%, F1 = 0.90, AUC = 0.95). This enhancement illustrates the importance of utilizing supportive emotional signals across different modalities. The confusion matrix displayed in Figure 3 indicates that the fusion model markedly lessened the misclassification of similar emotions, like fear and sadness, which often caused errors in unimodal systems. The balanced classification among six emotional categories (Table 1) demonstrates resilience to class imbalance. These results are consistent with recent studies on multimodal emotion recognition, yet the increased AUC indicates that incorporating empathetic HCI elements into model design could enhance subsequent interpretability and user confidence.
B. User Research: Assessing HCI Compassion and Inclusivity
Evaluations centered on users were carried out with 400 participants from various age groups and language backgrounds. As displayed in Table 7 and Figure 4, the system achieved notable usability (SUS = 82.3), trust (4.2/5), empathy perception (4.4/5), and accessibility (4.5/5). Qualitative feedback highlighted that the interface’s compassionate tone, culturally responsive attributes, and multilingual assistance promoted inclusivity.
Crucially, transparency aspects (like explainable AI) were noted as essential for fostering user trust, particularly in mental health settings where interpretability is as important as precision. These results highlight the significance of integrating HCI empathy design principles within ML pipelines.
C. Clinical Impact Indicators
Clinical impact assessments (Table 8, Figure 5) showed a decline in self-reported stress levels (Pre = 6.8, Post = 4.9) along with enhancements in emotional awareness (2.9 → 4.0) and intentions to seek help (3.1 → 4.3). Engagement with the system rose from an average of 14.2 to 23.6 sessions each month after deployment. These findings indicated that AI-powered empathetic interfaces can aid in self-managing mental health and may enhance clinical treatments.
Although these results are encouraging, longitudinal research is needed to confirm lasting effects. Additionally, collaboration with healthcare professionals for clinical validation is crucial prior to real-world implementation.
D. Comparative Analysis with Existing Tools
Compared to existing digital mental health platforms (e.g., rule-based chatbots, text-only sentiment detectors), the proposed system demonstrated three major advantages:
1. Accuracy Gains – Higher multimodal detection accuracy (91.2% vs. 70–80% reported in baseline tools).
2. Empathy & Trust – Higher user-reported empathy scores (4.4/5) compared to conventional digital tools, which often score below 3.5 in trust measures.
3. Inclusiveness – Unlike monolingual, accessibility-limited systems, our design integrated multilingual support and disability-inclusive features.
This positions the system as a benchmark for SDG 3 (mental well-being) and SDG 16 (inclusive digital systems) contributions.
E. Discussion
The findings show that integrating multimodal ML emotion identification with empathetic HCI design results in a synergistic effect: enhancing both algorithm effectiveness and user approval. This study stands apart from earlier works by incorporating transparency, accessibility, and inclusiveness into its design.
Nonetheless, obstacles persist in addressing algorithmic bias, guaranteeing data privacy (GDPR/HIPAA adherence), and performing thorough clinical validations. Tackling these obstacles will be crucial for expanding AI-driven mental health support systems worldwide. Conclusions: VI. Summary and Future Research
This research showcased the promise of merging artificial intelligence with human-computer interaction (HCI) concepts to enhance digital mental health assistance. The system attained technical robustness and user-centered acceptance by creating multimodal machine learning models for emotion recognition through text, voice, and facial expressions and integrating them into an empathetic, inclusive interface. Findings indicated that the suggested system surpassed unimodal baselines in accuracy (AUC = 0.95), while also improving trust, empathy perception, and accessibility. Clinical metrics indicated significant decreases in self-reported stress and enhanced user engagement, thus supporting SDG 3 (health and well-being) and SDG 16 (inclusive digital systems).
Even with these progresses, various restrictions persist. Recent assessments were restricted in time and extent, with data obtained from regulated settings instead of extended clinical applications. Additionally, algorithmic bias and privacy issues require ongoing attention, especially when systems are utilized in culturally varied and delicate health environments.
Future Directions
Building upon the contributions of this study, several future research avenues are proposed:
1. Cross-Cultural Validation – Expanding evaluations across diverse populations and linguistic groups to ensure inclusivity and mitigate cultural bias in emotion recognition.
2. Integration with Wearable Sensors – Combining physiological data (e.g., heart rate variability, skin conductance, EEG) with multimodal AI pipelines to improve emotion inference accuracy and personalization.
3. Long-Term Clinical Trials – Conducting longitudinal studies with clinical partners to validate sustained efficacy, safety, and integration with existing mental healthcare pathways.
4. Policy and Regulatory Implications – Collaborating with policymakers to align system deployment with ethical standards, privacy frameworks (GDPR, HIPAA), and emerging AI governance models to safeguard user rights and trust.
In conclusion, the fusion of AI-powered emotion recognition with empathetic HCI design represents a promising frontier in digital mental health interventions. With further validation and responsible deployment, such systems could complement human professionals, increase accessibility to care, and contribute meaningfully to the global mental health agenda.

Background: Groundwater is the main source of drinking water in Ogbia Local Government Area (LGA), Bayelsa State, Nigeria, where surface water is often compromised by oil exploration, poor sanitation, and waste disposal. Despite its importance, groundwater in this region is vulnerable to contamination from both geogenic and anthropogenic sources, raising concerns about long-term health implications. Objective: This study aimed to evaluate the physico-chemical quality of groundwater across selected communities in Ogbia LGA, compare measured values with World Health Organization (WHO) standards, and determine the implications for human health. Methods: A cross-sectional design was employed, involving the systematic collection of 50 groundwater samples from boreholes across 16 communities, including Oruma, Otuasega, Imiringi, Elebele, Otuokpoti, Kolo, Otouke, Onuebum, Ewoi, Otuogila, Otuabagi, Ogbia Town, Oloibiri, Opume, and Akiplai. Standardized laboratory analyses were conducted following WHO protocols to determine pH, conductivity, total dissolved solids, major ions, and heavy metals. Data were analyzed using descriptive statistics. Results: The findings showed that most parameters, including pH (6.4–7.1), conductivity (76–200 µS/cm), nitrates (2.4–6.4 mg/L), chloride (12–31 mg/L), calcium, magnesium, and hardness, were within WHO permissible limits, indicating generally acceptable groundwater quality. However, sodium exceeded WHO limits (200 mg/L) in 78% of samples (mean = 235 ± 45 mg/L; range = 150–320 mg/L), while iron exceeded permissible levels (0.3 mg/L) in 84% of samples (mean = 1.8 ± 0.6 mg/L; range = 0.5–3.2 mg/L). Elevated sodium poses risks of hypertension and cardiovascular disease, while excess iron is associated with gastrointestinal issues, organ damage, and aesthetic concerns such as metallic taste and staining. Spatial variations revealed stronger oilfield influences in Elebele, Imiringi, and Oloibiri, while central settlements such as Ogbia Town and Opume showed sanitation-related signatures. Seasonal fluctuations further exacerbated contaminant levels, particularly during rainfall-driven recharge. Conclusions: Groundwater in Ogbia LGA is broadly suitable for domestic use but compromised by systemic sodium and iron contamination. These exceedances, influenced by both natural hydrogeology and anthropogenic activities, present long-term public health challenges if unaddressed. Policy interventions should focus on routine groundwater monitoring, stricter regulation of oilfield activities, and improved waste management. Community-level treatment solutions, such as low-cost filters targeting sodium and iron removal, should be deployed. Public awareness programs and household water safety plans are also essential. Long-term strategies must integrate water governance with health and environmental policies to ensure sustainable access to safe water. The persistence of elevated sodium and iron in Ogbia groundwater poses a silent but significant health threat to residents, with implications for hypertension, cardiovascular disease, and gastrointestinal disorders. Safeguarding groundwater quality is therefore critical for reducing health inequalities and achieving Sustainable Development Goals 3 (Good Health and Well-being) and 6 (Clean Water and Sanitation) in Bayelsa State.

This study explores unethical HR practices in Nigerian organizations, focusing on nepotism, bribery, gender bias, and ethnic favoritism in recruitment, and their impact on organizational performance from 2009 to 2025. Despite various reforms, these unethical practices persist, undermining the fairness of recruitment processes, eroding employee morale, and negatively impacting productivity. This research is motivated by the need to assess the prevalence and ethical implications of nepotism and other unethical practices in Nigerian HRM, understand their impact, and propose practical solutions to enhance recruitment practices. The study aims to address four main objectives: (i) Assess the prevalence of nepotism and its ethical implications in Nigerian HRM practices; (ii) Examine recruitment challenges, including gender bias and ethnic favoritism; (iii) Analyze the impact of unethical HR practices on organizational performance; and (iv) Propose strategies for improving recruitment ethics and reducing nepotism. The study uses a mixed-methods approach, combining secondary data from reports by Transparency International, the World Bank, and McKinsey Nigeria, with qualitative insights from case studies and interviews. This methodology provides a comprehensive view of the state of HRM practices and the challenges faced by organizations in enforcing ethical recruitment. Results show that unethical practices, especially nepotism, bribery, and gender bias, continue to negatively affect both public and private sectors. Despite efforts such as HR ethics training and legal reforms, these practices persist due to political interference, weak enforcement, and a lack of technological adoption. Nepotism in recruitment was found to be particularly prevalent in government agencies, contributing to high turnover and reduced organizational performance. The study concludes that unethical HR practices continue to undermine recruitment processes, necessitating stronger anti-corruption policies, enhanced HR ethics training, and the integration of technology to increase recruitment fairness. It recommends strengthening legal frameworks, adopting automated recruitment systems, introducing whistleblower protections, and conducting regular audits. In the health sector, ethical recruitment is critical for improving patient care, reducing medical errors, and fostering trust in healthcare services.

Background: Antibiotic resistance and intestinal parasitic infections represent significant public health challenges in Southern Nigeria. The prevalence of Escherichia coli O157:H7, a pathogenic strain often associated with severe gastrointestinal diseases, along with intestinal parasites such as Hookworm, Entamoeba histolytica, and Ascaris lumbricoides, raises concerns about effective treatment options and the overall health burden. This study aimed to explore the prevalence of these infections and their associations with clinical outcomes in hospital patients, focusing on antibiotic resistance patterns and their impact on health. Objective: The primary objectives of this study were to determine the antibiotic resistance patterns of E. coli O157:H7 isolates, compare haematological profiles in patients with and without E. coli O157:H7 infection, and assess the prevalence and factors influencing intestinal parasitic infections in the patient population. Methods: A cross-sectional study was conducted at Central Hospital, Benin City, Nigeria. A total of 420 stool samples were screened for intestinal parasites and E. coli O157:H7. Antibiotic susceptibility testing was performed using the disc diffusion method, and PCR was used for molecular confirmation of E. coli O157:H7. Haematological parameters were analyzed using an autoanalyzer. Prevalence data were compared across age groups, gender, and diarrhea status. Statistical analysis was performed using GraphPad InStat software. Results: The study revealed that all E. coli O157:H7 isolates were resistant to amoxicillin-clavulanate, cefuroxime, and cloxacillin, with 80% resistance to ceftriaxone and gentamicin. However, 100% susceptibility to ofloxacin was observed. The overall prevalence of intestinal parasites was low (1.90%), with hookworm being the most common infection. No significant differences in parasite prevalence were observed based on age, gender, or diarrhea status. Haematological parameters showed no significant difference between patients with and without E. coli O157:H7 infection. Conclusions: The findings highlight a significant challenge in managing E. coli O157:H7 infections due to high antibiotic resistance, while also indicating a need for targeted interventions for parasitic infections in specific regions. No major haematological impact was observed in E. coli O157:H7-infected patients. In the short term, it is crucial to enhance diagnostic capabilities and increase education on antibiotic resistance among healthcare providers to ensure accurate identification of pathogens and appropriate treatment. In the mid-term, establishing a national surveillance system for antimicrobial resistance (AMR) will allow for better monitoring of resistance patterns and inform treatment protocols. In the long run, efforts should be focused on improving sanitation infrastructure, particularly in rural areas, and implementing targeted deworming programs to reduce the prevalence of intestinal parasites. Thus, these interventions collectively aim to address both antimicrobial resistance and parasitic infections, ultimately improving public health outcomes. Thus, this study underscores the dual burden of antibiotic resistance and parasitic infections in Nigeria, emphasizing the urgent need for robust public health interventions and continuous surveillance to mitigate these health risks.

ABSTRACT
Background: Convalescent coronavirus disease 2019 (COVID-19) refers to a series of clinical syndromes in patients with COVID-19 infection that follow the relevant discharge indications but do not fulfill the criteria for a clinical cure, and these patients are discharged from the hospital with residual multifunctional deficits, including coughing, fatigue, and insomnia. Due to the prolonged convalescent COVID-19 infection, patients continue to experience symptoms or develop new symptoms after three months of infection, and some symptoms persist for over two months without any apparent triggers, which has a significant impact on the health status and quality of life of the population. Patients with convalescent COVID-19 lack a definitive pharmacological treatment. Traditional Chinese medicine (TCM) exhibits a distinct, synergistic effect on the treatment of convalescent COVID-19. However, there exists a limited number of clinical trials on TCM with lower evidence levels in convalescent COVID-19; therefore, randomized trials are urgently required.
Methods: A multicenter, randomized, double-blind, placebo-controlled, phase II clinical trial was performed to evaluate the efficacy and safety of Shenlingkangfu (SLKF) granules in treating patients with convalescent COVID-19 and lung-spleen qi deficiency syndrome. Eligible participants were aged 18–75 years, had a confirmed or physician-suspected severe acute respiratory syndrome coronavirus 2 infection at least six months prior, and satisfied clinical criteria. Individuals with a history of severe pulmonary dysfunction or major liver and kidney illness or those on medications were excluded. Multicenter subjects satisfying all criteria were assigned (1:1) randomly into an intervention group and a control group. After a 2-day adjustment period, A total of 154 participants were randomly divided into an intervention group and a control group. The intervention group was given the SLKF granules orally once a bag, 16.9 g, twice daily, whereas the control group received the SLKF granule simulation at the same dosage. The trial was conducted over 14 days, with assessments performed at baseline and 14 days.
Results: The primary outcomes were the therapeutic efficacy rate and total clinical symptom score. The secondary outcomes included the fatigue self-assessment scale, pain visual analog scale, Pittsburgh sleep quality index, mini-mental state examination, hospital anxiety and depression scale, TCM syndrome score, C-reactive protein, erythrocyte sedimentation rate, and interleukin-6. Three routine examinations, liver and kidney function tests, and electrocardiography were used as safety indicators.
Conclusions:This study aimed to verify whether SLKF granules can significantly improve clinical symptoms, including fatigue, loss of appetite, cough, phlegm, and insomnia, in patients with convalescent COVID-19. For a comprehensive investigation, additional clinical trials with larger sample sizes and longer intervention periods are required.Clinical Trial Registration Center NCT1900024524, Registered on 26 January, 2024.

Mothers of children with learning disabilities often face significant challenges that can impact their mental health. This study aimed to examine the relationship between perceived social support and levels of anxiety, stress, and depression in this population. A descriptive-correlational design was employed, with a sample of 30 mothers of children with learning disabilities, selected via simple random sampling based on the Morgan table. Data were collected using the Multidimensional Scale of Perceived Social Support (Zimet et al., 1988) and the DASS-21 questionnaire (Lovibond & Lovibond, 1995), and analyzed with Pearson correlation and stepwise multiple regression. Findings revealed a significant negative correlation between social support and anxiety, stress, and depression, indicating that greater social support is associated with reduced levels of these mental health issues. These results underscore the role of social support in alleviating mental health challenges and suggest implications for counseling interventions targeting this group.

This study examined the efficacy of transdiagnostic cognitive-behavioral therapy (T-CBT) and acceptance-based therapy (ABT) in reducing emotional dysregulation and aggression in adolescents with elevated misophonia symptoms. Employing a quasi-experimental pre-test/post-test design with a control group, the research targeted 45 adolescents from Etrat Public Model High School in Khalkhal, Iran, diagnosed with high misophonia via psychiatrist evaluation and clinical interview. Participants were purposively sampled and randomly assigned to T-CBT (n = 15), ABT (n = 15), or a no-treatment control group (n = 15).
Interventions followed protocols adapted from Barlow et al. (2011) for T-CBT and Hayes et al. (2013) for ABT. Outcomes were measured using the Noise Sensitivity Screening Questionnaire (DSTS-S) , Buss and Perry Aggression Questionnaire (1992) , and Difficulties in Emotion Regulation Scale (DERS) . Data were analyzed via ANCOVA, controlling for baseline scores.
Results indicated significant reductions in emotional dysregulation and aggression in both treatment groups compared to the control (p < 0.05). No significant differences emerged between T-CBT and ABT, suggesting both interventions are viable for addressing misophonia-related symptoms. Findings underscore the comorbidity of emotional dysregulation and aggression in adolescents with misophonia and highlight the clinical utility of transdiagnostic and acceptance-based approaches. Future research should explore long-term outcomes and comparative effectiveness of these therapies.

Hydatid disease, caused by the larval stages of Echinococcus species, remains a significant yet underprioritized global health challenge, particularly in low-resource endemic regions. This systematic review synthesizes recent advances and persistent challenges in the diagnosis, management, and control of hydatid cyst disease, drawing on evidence from the past five years. Despite progress in diagnostic imaging, such as MRI diffusion-weighted imaging and recombinant antigen-based serology, and minimally invasive therapies like PAIR (puncture, aspiration, injection, re-aspiration), substantial gaps remain. Diagnostic tools are often inaccessible in rural areas, and therapeutic strategies lack standardization, particularly for alveolar echinococcosis and high-risk populations such as children and immunocompromised individuals. Climate change and socioeconomic factors continue to drive disease transmission, with E. multilocularis expanding into new regions. Control efforts, while successful in some areas through integrated One Health approaches, face barriers including underfunded veterinary infrastructure and vaccine hesitancy. This review highlights the need for decentralized diagnostic technologies, standardized treatment protocols, and climate-resilient control programs. Future research must prioritize underrepresented populations and cost-effectiveness analyses to mitigate the global burden of hydatid disease.

This study aimed to investigate the relationship between communication beliefs, the health of the family of origin, and fear of marriage among university students. Employing a descriptive-correlational design, the research was conducted with 186 students from Islamic Azad University, Khalkhal Branch, selected from a population of 360 using Morgan's table. Stratified sampling was applied to ensure representation across major fields of study. Data were collected using three instruments: the Premarital Fears Questionnaire (measuring fear of marriage), the Communication Beliefs Questionnaire (assessing beliefs about communication), and the Major Family Health Scale (evaluating family of origin health). Data analysis utilized Pearson correlation and stepwise multiple regression methods. Pearson correlation analysis revealed a significant positive correlation between communication beliefs and fear of marriage. Stepwise multiple regression showed that communication beliefs and family health together accounted for 95.9% of the variance in fear of marriage (p < 0.001), with communication beliefs emerging as the strongest predictor. These findings underscore the significant influence of communication beliefs and family health on fear of marriage, offering valuable insights for developing interventions to address marriage-related anxieties among young adults.

Background: Groundwater contamination from open dumpsites poses a growing environmental and public health threat in rapidly urbanizing regions of Nigeria. Inadequate waste management and the absence of engineered landfills enable leachate to infiltrate aquifers, threatening potable water safety and community health. Objective: This study investigates the vertical and lateral migration of leachate and assesses groundwater vulnerability across ten major dumpsites in Port Harcourt, Nigeria, using geoelectrical methods. Methods: Vertical Electrical Sounding (VES) and 2D Electrical Resistivity Tomography (ERT) were conducted at ten dumpsites using the Schlumberger array configuration. Zones of low resistivity, indicative of leachate impact were identified and correlated with hydrogeological conditions. Subsurface contamination depths and aquifer locations were interpreted using inversion models. Results: All ten sites showed evidence of leachate migration, with contamination depths ranging from 2 m to over 24 m. Deep leachate penetration was observed at Rumuola and Eliozu, while shallower infiltration occurred at Oyigbo and Rumuolumeni. High-resistivity zones (>1000 Ωm), typically representing clean aquifers, were detected below the contaminated zones at depths exceeding 14 m Conclusions: Leachate plumes from unregulated dumpsites pose a widespread threat to shallow groundwater systems in Port Harcourt. The results underscore the influence of local geology on contaminant behavior and affirm the utility of resistivity methods for groundwater risk assessment. Contaminated aquifers expose residents to toxic metals and pathogens, increasing risks of chronic illnesses, reproductive disorders, and developmental challenges. Protecting these water sources is essential for achieving Sustainable Development Goals (SDGs) 6 (Clean Water) and 11 (Sustainable Cities). Immediate containment measures such as engineered liners and leachate recovery systems are urgently needed at high-risk sites. Strategic borehole siting, routine groundwater monitoring, and a shift from open dumping to sanitary landfilling must be prioritized in environmental policy and urban planning.

Background: The growing trend of integrated healthcare services within physician groups has improved care delivery by enhancing convenience, efficiency, and care coordination. However, it has also raised concerns about financial incentives potentially driving overutilization. Objective: We examine the impact of distribution method (traditional third-party referral versus physician-managed via Rx Redefined technology platform) on the quantity of urinary catheters supplied to Medicare patients. Methods: We analyzed utilization patterns for urological catheters (HCPCS codes A4351, A4352, and A4353) using 2021 Medicare claims data. We identified 54 urology specialists in core metropolitan areas who were enrolled in the Rx Redefined platform throughout 2021 and compared their utilization patterns with unenrolled urologists in the same regions. For enrolled physicians, who managed approximately 40 percent of their prescriptions through the platform, we also compared utilization between physician-managed and third-party distribution methods. Results: For catheter services A4351 and A4352, when distribution was managed by third parties, we found no significant differences in utilization (i.e. units supplied) between enrolled and unenrolled physicians. However, physician-managed distribution through Rx Redefined resulted in significantly lower utilization compared to third-party vendor distribution by non-enrolled physicians (p < 0.001 for both codes). In paired analysis of enrolled physicians, direct management showed significantly lower utilization compared to third-party distribution for A4351 (p = 0.014), but this difference was not significant for A4352 (p = 0.62). Conclusions: These findings demonstrate that physician-managed catheter distribution does not lead to increased utilization. In fact, for certain catheter types, physician-managed distribution may result in lower utilization compared to traditional third-party referral methods, suggesting a potential reduction in oversupply and improved efficiency.

Background: Sri Lanka has a well-established National Blood Transfusion
Service that provides quality assured blood bank service.
However, the information flow is inefficient and less utilized for
evidence-based decision-making. The statistics unit of National
Blood Centre is unable to produce Annual Statistics Report
timely due to the difficulty in analysing and making reports
manually utilizing the considerable amount of data collected
throughout the year. To address this, an electronic Health
Information Management System was proposed as a solution for
the inefficiency of the data flow for statistical purposes. Objective: 1. General Objective
Facilitate decision-making by developing, implementing and
evaluating an electronic information management system to
capture monthly statistics data from island wide blood banks.

Identify the requirements of the system (MSR-NBTS)
Customize DHIS2 to fulfil the identified
requirements
Testing and hosting the system at National Blood
Centre Narahenpita
Evaluation of usability and cost-effectiveness of the
system Methods: A Monthly Statistics Reporting System was designed and
developed using DHIS2, which is a Free and Open Source
Software (FOSS) to fulfil the requirements of the National Blood
Transfusion Service. To evaluate the new system, a qualitative
study was conducted using semi-structured interviews amongst
a selected study population of 17 participants within the NBC
Cluster, which includes 11 blood banks in Colombo area. The
gathered data was analysed using a thematic analysis techniques
and the emerging categories and themes were used in the
subsequent discussions. Results: Problems of calculation, usability, reliability, utilization of
data and availability of reports were identified in the paper
based system. Results shows that the new electronic system has
high usefulness, ease of use, ease of learn, satisfaction and cost
effectiveness with accepted enhanced features of the interface.
According to the interviews, participants expressed that the
likelihood of using this system in the future is high. Conclusions: Almost all the participants in this research readily accepted
new electronic information management system. Therefore, it
will assure the sustainability of the new system. Because of the
real time updated dashboard, it will help most of the blood bank
functions by facilitating administrative decision-making
efficiently.

Background: Unskilled birth delivery significantly contributes to maternal and neonatal mortality in Sub-Saharan Africa, especially Nigeria, due to cultural beliefs, poverty, poor health access, and weak policies. Despite efforts to promote skilled attendance, many women still use traditional birth attendants (TBAs) and home deliveries. This study explores the socio-demographic, cultural, and systemic factors driving this trend, offering evidence for better policies and health interventions. Objective: This study examined the socio-demographic and socio-cultural barriers to the utilization of skilled delivery services among women of reproductive age in Nigeria. Methods: A cross-sectional design utilizing both quantitative surveys and qualitative interviews was employed. The study involved 1,200 expectant and recently delivered women across urban, semi-urban, and rural regions in Nigeria. Data on socio-demographics, beliefs, access factors, and healthcare usage were collected. Policy documents and intervention records were reviewed, while focus groups provided depth to cultural and systemic themes. Descriptive and inferential statistics were applied using SPSS, and thematic analysis was used for qualitative data. A literature triangulation approach was used to validate findings with existing research. Results: The study revealed that low maternal education, poverty, and rural residence strongly predicted unskilled delivery service usage. Cultural norms that regard childbirth as a domestic or spiritual event influenced avoidance of hospitals. Access barriers included poor transport, cost, and distrust in formal healthcare. Geographic inequality was evident, with rural regions lacking health infrastructure. Policy review showed limited reach and weak enforcement of maternal care programs. However, when community-based midwives or mobile clinics were available, skilled birth attendance improved significantly. Conclusions: The persistence of unskilled deliveries is a multifaceted issue driven by intersecting socio-cultural, economic, geographic, and institutional factors. Despite policy efforts, gaps remain in cultural sensitivity, resource allocation, and infrastructure coverage. To address maternal health effectively, interventions must be locally adapted, multidimensional, and equity-focused. To address unskilled delivery use, maternal health education should leverage community programs with local languages and cultural context. Rural healthcare infrastructure must expand via mobile clinics and trained midwives to improve access. Skilled delivery costs should be subsidized or covered by insurance to remove financial barriers. Traditional birth attendants could be trained and integrated into the formal health system under supervision. Finally, maternal health policies require regular review, adequate funding, and strict monitoring to ensure impact. These steps are vital to reducing maternal mortality in Nigeria and Sub-Saharan Africa. Unskilled delivery service utilization represents a critical barrier to maternal and neonatal health improvements in Nigeria and Sub-Saharan Africa. Addressing this issue through targeted socio-cultural, structural, and policy interventions is essential to reduce preventable maternal deaths and achieve Sustainable Development Goal 3 on maternal health.

Background: Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency affecting preterm infants with high mortality and morbidity. With suboptimal and incomplete methods of prevention of NEC, early diagnosis and treatment can potentially mitigate the impact of NEC. This study explores the application of machine learning techniques, specifically Random Forest and Extreme Gradient Boosting (XG Boost), to improve early and accurate NEC and FIP diagnosis. Objective: To evaluate the effectiveness of sampling techniques in addressing class imbalance and to identify the optimal machine learning (ML) classifiers for predicting necrotizing enterocolitis (NEC) and focal intestinal perforation (FIP) in preterm infants. Methods: We developed ML models using 49 clinical variables from a retrospective cohort of 3,463 preterm infants, using clinical data from the first two weeks of life as input features. We applied various sampling strategies to address the inherent class imbalance, and then combined various sampling strategies with different ML algorithms. Parsimonious models with selected key predictors were evaluated to maintain predictive performance comparable to the full-featured (complex) models. Results: The parsimonious generalized linear model (GLM) with SMOTE sampling achieved an area under the receiver operating characteristic curve (AUROC) of 0.79 for NEC prediction, closely approximating the complex model's AUROC of 0.76. For FIP prediction, parsimonious models of GLM with ADASYN sampling and XG Boost with TOMEK sampling achieved AUROC values exceeding 0.90, comparable to those of the corresponding complex models. For both NEC and FIP, the area under the precision-recall curve (AUPRC) surpassed the respective prevalence rates, indicating strong performance in identifying rare outcomes. Conclusions: We demonstrate that targeted sampling strategies can effectively mitigate class imbalance in neonatal datasets, and simplified models with fewer variables can offer comparable predictive power, enhancing the performance of ML-based prediction models for NEC and FIP.

Background: Workplace stress has emerged as a pressing public health issue in Nigeria, where approximately 75% of employees experience work-related stress significantly higher than the global average. This stress, exacerbated by systemic labor policy gaps, cultural stigma, and economic instability, contributes to burnout, reduced productivity, and economic losses. Despite emerging HRM interventions, mental health remains underprioritized in organizational strategies, particularly within sectors such as healthcare, banking, construction, and the informal economy. There is a critical need for evidence-based, culturally adapted HRM strategies that address these unique challenges in Nigeria’s workforce. Objective: This study seeks to examine the prevalence and sector-specific drivers of workplace stress in Nigeria, evaluate the effectiveness and limitations of current HRM interventions, identify key socio-cultural and structural barriers hindering mental health program implementation, and propose actionable, evidence-based strategies that are contextually tailored to Nigeria’s diverse workforce. Through a synthesis of localized research and global best practices, the study aims to provide a strategic roadmap for enhancing mental health resilience in Nigerian workplaces. Methods: A narrative review methodology was employed, guided by qualitative synthesis and thematic analysis frameworks. Literature was sourced from global and regional databases (PubMed, PsycINFO, AJOL, Scopus) spanning 2018–2024, including peer-reviewed articles, policy reports, and grey literature. Inclusion focused on empirical and policy studies relevant to Nigerian HRM practices. NVivo 12 was used for thematic coding, and a gap analysis framework was applied to identify unaddressed areas. A total of 42 studies met the inclusion criteria. Expert validation and triangulation with global data enhanced rigor. Results: Burnout rates in Nigeria are among the highest globally, with 35% in healthcare, 32% in retail, and 29% in banking. Women and younger workers face disproportionate stress burdens. HRM strategies such as Employee Assistance Programs (EAPs) and Flexible Work Arrangements showed the highest effectiveness but had limited adoption due to cost, stigma, and infrastructure gaps. Digital mental health tools, though cost-effective, had low uptake (23%) due to digital illiteracy. Barriers included cultural stigma, weak labor policies, leadership apathy, and lack of ROI measurement. Promising strategies identified include faith-based EAPs, peer networks, mobile clinics, and stigma-reduction campaigns, particularly when culturally embedded and supported by community leaders. Conclusions: Workplace stress in Nigeria is a systemic challenge rooted in socio-economic, cultural, and organizational structures. Although several HRM interventions show promise, their effectiveness is hindered by low adoption, poor contextual fit, and limited legal enforcement. Evidence suggests that when mental health strategies are localized and culturally endorsed via faith leaders, digital tools, or flexible work, they yield improved employee retention, lower absenteeism, and better organizational resilience.

Background: Nigeria faces severe economic losses ($14 billion annually) and high youth unemployment (33.3%) due to persistent skills gaps, exacerbated by sectoral disparities (e.g., 68% ICT shortages vs. 63% agricultural deficits) and systemic inequities in education and vocational access. Despite growing HRM interventions, empirical evidence on their efficacy remains limited, necessitating a comprehensive review to guide policy. Objective: This study analyzes Nigeria’s sector-specific skills gaps, evaluates the effectiveness of HRM interventions (apprenticeships, digital upskilling, PPPs), and proposes actionable frameworks to align workforce development with labor market demands. Methods: A narrative review of peer-reviewed literature (2015–2023), institutional reports (World Bank, PwC, NBS), and case studies (e.g., Andela’s model) was conducted. Data were synthesized to compare regional benchmarks (Kenya’s TVET, South Africa’s HRM reforms) and Nigeria’s performance (talent readiness score: 42/100). Results: Key findings include: (1) Vocational training (60% readiness) outperforms tertiary education (40%); (2) Apprenticeships and PPPs show high impact (30% job placement increase); (3) Urban-rural and gender disparities persist (women 30% less likely to access training). Private-sector models demonstrate scalability but require policy support. Conclusions: Nigeria’s skills crisis demands urgent, context-sensitive interventions. Blended strategies (e.g., industry-aligned curricula, gender-inclusive vocational programs) could unlock 5% annual GDP growth. Prioritize: (1) National skills councils to standardize certifications; (2) Tax incentives for employer-led training; (3) Digital infrastructure for rural upskilling. Closing Nigeria’s skills gaps would mitigate economic losses, reduce inequality, and enhance global competitiveness, transforming its youth bulge into a sustainable demographic dividend.

Background: Central venous catheterization (CVC) is a very common procedure performed across medical and surgical wards as well as intensive care units. It provides relatively extended vascular access for critically ill patients, in order to the administer intricate life-saving medications, blood products and parenteral nutrition.
Major vascular catheterization provides a risk of easy accessibility and dissemination of catheter related infections as well as venous thromboembolism. Therefore, its crucial to ensure following standardized practices while insertion and management of CVC in order to minimize the infection risks and procedural complications. The aim of these central line insertion guidelines is to address the primary concerns related to predisposition of Central line associated blood stream infections (CLABSI). These guidelines are evidence based and gathered from pre-existing data associated with CVC insertion.
The most common used sites for central venous catheterization are internal jugular and subclavian veins as compared to femoral veins. Catheterization of these vessels enables healthcare professionals to monitor hemodynamic parameters while ensuring lower risks of CLABSI and thromboembolism. Femoral vein is less preferred due to advantage of invasive hemodynamic monitoring and low risk of local infection and thromboembolic phenomena.
CVC can be inserted using Landmark guided technique and ultrasound guided techniques. Following informed consent, the aseptic technique for CVC insertion includes performing appropriate hand hygiene and ensuring personal protective measures, establishing and maintaining sterile field, preparation of the site using chlorhexidine, and draping the patient in a sterile manner from head to toe. Additionally, the catheter is prepared by pre-flushing and clamping all unused lumens, and the patient is placed in the Trendelenburg position. Throughout the procedure, maintaining a firm grasp on the guide wire is essential, which is subsequently removed post-procedure. It is followed by flushing and aspirating blood from all lumens, applying sterile caps, and confirming venous placement. Procedure is ended with cleaning the catheter site with chlorhexidine, and application of a sterile dressing.
Hence, formal training and knowledge of standardized practices of CVC insertion is essential for health care professionals in order to prevent CLABSI. Our audit assesses the current practices of doctors working at a tertiary care hospital to analyze their background knowledge of standard practices to prevent CLABSI during insertion of CVC. Objective: This study was aimed to audit and re-audit residents’ practices of central venous line insertion in medical and nephrology units of A Tertiary Care Hospital of Rawalpindi, Pakistan and to assess the adherence of residents to checklist and practice guidelines of CVC insertion implemented by John Hopkins Hospital and American Society of Anesthesiologists. Methods: This audit was conducted as a cross sectional direct observational study and two-phase quality improvement project in the Medical and Nephrology Units of a Tertiary Care Hospital of Rawalpindi from December 2023 to February 2024.
After taking informed consent from patients and residents, CVC insertion in 34 patients by 34 individual residents was observed. Observers were given a purposely designed observational tool made from John Hopkins Medicine checklist and ASA practice guidelines for central line insertion, for assessment of residents’ practices.
First part contained questions regarding the demographic details of residents such as age, gender, year of post graduate training, and parent department, and data related to the procedure such as date and time of procedure, need of CVC discussion during rounds, site of CVC insertion, catheter type and type of procedure (Landmark guided CVC or Ultrasound guided CVC insertion). Second part included direct observational checklist based on checklist provided for prevention of intravascular catheter-associated bloodstream infections to audit the practices of residents during CVC insertion that included: adequate hand hygiene before insertion, adherence to aseptic techniques, using sterile personal protective equipment and sterile full body drape of patient, choosing the best insertion site to minimize infections based on patient characteristics.
The parameters observed to be done completely were scored "1" and the items not done were scored "0". The cumulative percentage of performed practices according to checklist, was satisfactory if it was 80% or more and unsatisfactory if it was less than 80%.
After initial audit, participants were given pamphlets with checklist incorporating John Hopkins Medicine checklist and ASA practice guidelines for CVC insertion. Re audit was performed one month after the audit, including same participants who participated in initial audit. The results of audit and re-audit were analyzed using SPSS version 25. Mean +/- SD was calculated for quantitative variables and Number (N) percentage was calculated for qualitative variables. Z- Test was applied on proportions of parameters and test scores to calculate Z –score and P value (<0.05 was significant). Results: Among the 34 participants, 44% of the participants belonged to Nephrology Department and 56% of participants belonged to Department of Internal Medicine.
32.3% residents were in their first year, 14.7% in second, 14.7 in third year, 17.6% in fourth year and 17.6% in 5th/Final year of training.
47% of the participants were male and 53% were female. Participants were aged between 27 and 34 years old, the median age at the time of audit was 29 years.
Landmark guided CVC insertion was performed in Subclavian Vein (73.5%) and Internal Jugular Vein (26.5%).
Post audit practices were improved from 73.5% to 94%. Conclusions: Our audit found that many of the residents adopted inadequate practices because of lack of proper training and institutional guidelines for CVC insertion. Our re-audit elaborated an improvement in the practices of residents following intervention with educational material. Our study underscores the importance of structured quality improvement initiatives in enhancing clinical practices and patient outcomes.

Background: Noncommunicable diseases (NCDs) pose a significant burden in the Philippines, with cardiovascular and cerebrovascular diseases among the leading causes of mortality. The Department of Health implemented the Philippine Package of Essential Non-Communicable Disease Interventions (Phil PEN) to address this issue. However, healthcare professionals faced challenges in implementing the program due to the cumbersome nature of the multiple forms required for patient risk assessment. To address this, a mobile medical app, the PhilPEN Risk Stratification app, was developed for community health workers (CHWs) using the extreme prototyping framework. Objective: This study aimed to assess the usability of the PhilPEN Risk Stratification app using the (User Version) Mobile App Rating Scale (uMARS) and to determine the utility of uMARS in app development. The secondary objective was to achieve an acceptable (>3 rating) score for the app in uMARS, highlighting the significance of quality monitoring through validated metrics in improving the adoption and continuous iterative development of medical mobile apps. Methods: The study employed a qualitative research methodology, including key informant interviews, linguistic validation, and cognitive debriefing. The extreme prototyping framework was used for app development, involving iterative refinement through progressively functional prototypes. CHWs from a designated health center participated in the app development and evaluation process – providing feedback, using the app to collect data from patients, and rating it through uMARS. Results: The uMARS scores for the PhilPEN Risk Stratification app were above average, with an Objective Quality rating of 4.05 and a Personal Opinion/Subjective Quality rating of 3.25. The mobile app also garnered a 3.88-star rating. Under Objective Quality, the app scored well in Functionality (4.19), Aesthetics (4.08), and Information (4.41), indicating its accuracy, ease of use, and provision of high-quality information. The Engagement score (3.53) was lower due to the app's primary focus on healthcare rather than entertainment. Conclusions: The study demonstrated the effectiveness of the extreme prototyping framework in developing a medical mobile app and the utility of uMARS not only as a metric, but also as a guide for authoring high-quality mobile health apps. The uMARS metrics were beneficial in setting developer expectations, identifying strengths and weaknesses, and guiding the iterative improvement of the app. Further assessment with more CHWs and patients is recommended.
