Pilot and Feasibility Studies

Introduction Diabetes distress describes the psychological and emotional burden of living with diabetes and is associated with reduced self-management and adverse diabetes outcomes. Clinical guidelines recommend routine assessment and management of diabetes distress, but this is not always implemented. Therefore, there is a need to develop approaches to deliver emotional health support in routine clinical care more effectively. We describe here the protocol for a study to I) assess the feasibility of implementation of the D-stress Pathway, comprising Enhanced Usual Care (EUC) and an online, group-based, psychological diabetes distress reduction intervention called REDUCE, ii) evaluate the feasibility of the study protocol iii) detect an effect signal of diabetes distress score and Interstitial Glucose Time in Range and iv) refine initial programme theories of how both interventions (EUC and REDUCE) work, for whom, and under what circumstances. Methods This feasibility study includes a multicentre trial within a cohort design (TWICs) where sites have a staggered exposure to the interventions alongside a realist process evaluation. Four UK NHS diabetes services will recruit 80 adults with type 1 diabetes ([≥]1 year) using continuous glucose monitoring (CGM) ([≥]3 months). All participants will receive EUC and provide monthly data over 7 months on diabetes distress (measured by the Type 1 Diabetes Distress Assessment System (T1DDAS) and interstitial glucose measured by using continuous glucose monitoring. Participants with elevated diabetes distress, will be offered the six-week, group-based, online REDUCE intervention plus EUC, compared to EUC alone. Up to twenty participants with type 1 diabetes, ten family members/friends, sixteen healthcare professionals delivering EUC and five REDUCE facilitators will be interviewed to explore their experience of receiving training and delivering the D-stress Pathway. Up to 20 EUC consultations and REDUCE sessions will be observed. Analysis Feasibility will be assessed against pre-specified progression criteria and analysed descriptively using summary statistics. Primary outcomes include baseline level of diabetes distress, recruitment rate, intervention uptake, and data completeness, which will be analysed descriptively. Qualitative data will be analysed using framework analysis guided by realist programme theories developed for this study. Ethics Ethics approval has been granted by NHS Research Ethics Committee (REC) (Bromley REC: 25/LO/0469) and Health Research Authority obtained. All participants will provide informed consent. Trial registration no: Registered at ClinicalTrials.gov number NCT07193446 on 26/11/2025. Protocol and statistical analysis plan: The trial protocol and statistical analysis plan can be accessed at ClinicalTrials.gov.

This study protocol combines clinical simulations with climatic chamber experiments, to evaluate 1) the impact of heat stress on hospital nurses physiological strain, physical and mental fatigue, vigilance, and clinical performance; and 2) the efficacy of a practical cooling intervention (i.e. electric fan) in mitigating the negative impact of heat stress. UK-based, registered adult nurses working in hospital settings will be recruited to partake in a repeated-measures cross-over design study, consisting of five separate 3-hour experimental sessions simulating clinical work, and taking place within a climatic chamber at Southampton General Hospital (UK). Sessions will differ by ambient temperature and cooling intervention as follows: 1) control (CTR; 18{degrees}C, 50% relative humidity [RH]); 2) warm (WARM; 26{degrees}C, 50%RH); 3) warm with electric fan (WARM+FAN; 26{degrees}C, 50%RH); 4) hot (HOT; 34{degrees}C, 50%RH); 5) hot with electric fan (HOT+FAN; 34{degrees}C, 50%RH). This study has been registered on a publicly accessible clinical trial registry (ISRCTN45793399). During each session, participants will first complete a standardised fatigue-induction protocol simulating shift work (i.e. low-intensity cycling with cognitive tasks); followed by a simulated hospital ward round involving six simulated patients and two simulated cardiac arrest scenarios. Nursing cognitive and physical performance will be assessed using a standardised observational assessment battery, along with objective cardiopulmonary resuscitation (CPR) performance metrics. Physiological responses will be assessed by monitoring changes in core temperature (Tcore), skin temperature (Tskin), heart rate, and whole-body sweat loss (WBSL). Fatigue and vigilance will be measured using the Swedish Occupational Fatigue Inventory (SOFI) and Brief Psychomotor Vigilance Task (PVT-B), respectively. Baseline (i.e. prior to fatiguing protocol) to post simulation changes in 1) vigilance assessed via the PVT-B (i.e. a determinant of role-specific cognitive performance); 2) CPR quality score (i.e. a determinant of role-specific physical performance); and 3) Tcore (i.e. a determinant of thermo-physiological state); will be analysed using linear mixed models to determine the effects of ambient temperature and cooling intervention on nurses clinical and physiological performance. By providing a controlled methodological framework for assessing the effects of heat exposure on hospital nurses physiological, perceptual, and clinical performance, this study will provide empirical evidence on air temperature-related changes in nursing performance and physiological strain and the role of cooling interventions in modifying these responses. This will support the development of evidence-based climate adaptation strategies to protect healthcare staff wellbeing and maintain patient safety during periods of extreme heat.

Fractures, especially simple fractures, are a common childhood injury. The purpose of this research was to work with parents to develop and test the usability of an animated video and an interactive infographic about simple fractures in children. Prototypes were designed collaboratively between researchers, healthcare experts, and parents. After refinement, prototypes were evaluated by parents through usability testing in an urban emergency department waiting room in Alberta. Results were positive and overall, the tools were highly rated, suggesting that arts-based digital knowledge translation tools are useful mediums for sharing health information about simple fractures with parents.

Background: Yoga may support changes in dietary intake and/or physical activity levels, supporting sustainable weight loss. However, previous research has focused on yoga postures (asanas) rather than breathing practices (pranayama). This study used the proof-of-concept stage in the ORBIT model to evaluate feasibility, acceptability, and preliminary efficacy of a breath-based yoga program integrated within a behavioral weight loss (BWL) intervention. Methods: Fifteen participants with overweight or obesity (BMI: 31.3 +/- 4.3, 80% female) were enrolled in a 16-week, single-arm, group-based BWL intervention which included four breath-based yoga sessions/week, individualized daily goals for energy intake reduction, and progressive aerobic exercise recommendations. Primary outcomes included prespecified benchmarks enrollment, retention, adherence, and acceptability. Secondary outcomes included changes in body weight and composition, metabolic health indices (e.g., blood pressure, fasting glucose, abdominal obesity), physical activity, appetite, and dietary intake. Results: Mean percent weight loss was 6.5 +/- 6.0%, exceeding the pre-defined proof-of-concept benchmark. Recruitment and adherence exceeded established benchmarks, with mean in-class attendance of 84.1 +/- 14.6% and adherence to the prescribed duration of at-home yoga sessions averaging 85.5 +/- 38.4%. However, retention was lower than the pre-specified benchmark (73% vs 80%). Positive changes were observed in waist circumference, blood pressure, and appetite traits. Self-reported satisfaction with the program and outcomes were acceptable (mean ratings >6/10). Conclusions: A BWL with a breath-based, low-intensity yoga can lead to acceptable weight loss with potential benefits in key behavioral and metabolic health indices. Recruitment, high adherence, and satisfaction demonstrated feasibility.

Background Falls in hospitals are associated with injuries, deaths and poor patient outcomes. Although clinical guidelines recommend educating hospital patients about how to prevent falls, not all hospitals systematically deliver evidence-based patient falls education. The primary aim of this study is to implement and evaluate the effectiveness of delivering a research-informed education program called the Safe Recovery Program with ward support on rates of falls and falls-related injuries in hospitals. The secondary aims include measuring changes in patient and staff knowledge and awareness about falls prevention and identifying barriers and facilitators to staff and patients taking action to reduce hospital falls. Methods The trial will adhere to the Consolidated Standards of Reporting Trials guidelines. Twelve wards will be recruited from five Australian hospitals over a 65-week period. A stepped-wedge cluster randomised controlled trial design will be used with unidirectional crossover from control to experimental conditions together with randomisation of when each cluster makes the transition. The crossovers will occur at 12 timepoints, each five weeks apart. Alongside the trial, patients and staff on participating wards will be recruited for interviews and qualitative data analyses will be conducted to understand how to optimise implementation. The experimental condition involves usual care plus delivery of the Safe Recovery Program. For the Safe Recovery Program, supervised allied health assistants will deliver brief falls education programs to all suitable patients in designated wards, reinforced by all ward staff. Falls champions, who are registered nurses and allied health professionals, will provide Safe Recovery Program training for staff, using a train-the-trainer model. The ward staff will also be trained in how to support hospital patients to adopt safe behaviours. The primary outcome will be falls per 1000 patient bed days. The secondary outcomes will be: (i) injurious falls per 1000 patient bed days (ii) patient and staff changes in falls awareness, knowledge and motivation; and (iii) barriers and enablers to hospital staff engaging in behaviour change and program implementation. An economic evaluation will also be conducted to estimate the incremental cost effectiveness of implementing the Safe Recovery intervention. Ethics and Dissemination Ethics approvals have been obtained from The Royal Melbourne Hospital Human Research Ethics Committee (HREC/113864/MH-2024). The findings will be disseminated through peer-reviewed journals, workshops and conferences. Consumer team investigators will guide the communication of findings to the target audiences, including older patients, hospital staff, healthcare managers and policy makers.

Background Temperature instability during neonatal transport contributes to adverse outcomes in preterm and low birth weight infants. Hypothermia in this population is associated with increased risk of intraventricular haemorrhage (IVH), sepsis, and death. Current transport temperature management is reactive and manually controlled. The Heating On Transport WitH prEtErm and Low birth weight neonates using Servocontrol patient temperature management system (HOTWHEELS) trial aims to determine whether automated, servo-controlled thermoregulation provides superior thermal stability compared to standard care and reduces hypothermia-associated adverse outcomes. Methods This prospective, randomised, superiority trial is conducted by the Newborn Emergency Transport Service of Western Australia. Infants with a gestational age of less than or equal to 34 weeks and/or weight of 1500 g requiring transport are randomised to serve-controlled or standard thermal care. The primary outcome is the proportion of infants with a temperature between 36.5 and 37.5 degrees Celsius on arrival at the receiving neonatal unit. Secondary outcomes include the incidence of IVH in the first 7 days, mortality before discharge, the incidence of moderate (<36.0) and severe (<35.0) hypothermia for greater than 15 minutes and the temperature change during transport. Trial registration: ANZCTR12624000503527. Impact HOTWHEELS is the first randomised trial in neonatal transport to evaluate servo-controlled temperature control. We believe the findings will inform standards of temperature control during transport for preterm and low birth weight infants.

BACKGROUND Safe and effective antidepressant deprescribing strategies are needed in general practice where most antidepressant prescribing occurs. METHODS We conducted a pragmatic, cluster-randomised controlled trial in general practice to test invitation to general practitioner (GP) review combined with resources to inform shared decision-making and guide hyperbolic tapering for stopping antidepressants compared to usual care. Adults taking antidepressants for longer than 12 months were recruited from 26 Australian GP practices between March 2023 and November 2024, irrespective of their intention to stop or depression or anxiety symptom scores. The primary outcome was cessation at 12 months. Secondary outcomes included cessation at 6 months, and >75% dose reduction and depression, anxiety and withdrawal symptom scores at 6 and 12 months. RESULTS Overall, 483 patients were randomised. Mean age was 50 years; 73% were women; mean duration of antidepressant use was 14.1 years. Cessation at 12 months was observed in 32 of 215 (14.9%) intervention and 16 of 187 (8.6%) usual care patients (odds ratio (OR) = 1.95 [95%CI, 1.00 to 3.81]; p=0.050). Cessation at 6 months was observed in 11.7% intervention vs 4.8% usual care (OR = 2.68; 95%CI, 1.18 to 6.05), and >75% dose reduction at 12 months in 19.6% intervention vs 9.9% usual care (OR = 2.28; 95%CI, 1.20 to 4.31). Symptom scores were similar between groups. No adverse events were attributable to the intervention. CONCLUSIONS In general practice, invitation to GP antidepressant review combined with information and guidance on hyperbolic tapering can support cessation or dose reduction without causing adverse effects or relapse. Absolute cessation rates were modest but still meaningful given the high prevalence of long term antidepressant use. TRIAL REGISTRATION ANZCT registry identifier, ACTRN12622001379707p.

Background: Large language models (LLMs) configured as virtual patients may expand structured practice of clinical reasoning in health professions education. Before testing effectiveness, it must be established whether students engage with them and whether the resulting scores are complete, reliable, and related to performance with real patients. Our earlier pilot randomized trial found very low engagement with a less structured LLM-based approach. Objective: This study aimed to assess the feasibility (adherence, acceptability, and data completeness) of a revised, structured LLM-based clinical reasoning laboratory (Laboratorio de Inteligencia Artificial [LIA]) in undergraduate physical therapy education and to explore its measurement properties, including its association with clinical judgment with a real patient assessed with the Lasater Clinical Judgment Rubric (LCJR). Methods: In this single-arm pilot feasibility study, 27 third-year physical therapy students at a Spanish university completed, in 2024-2025, 3 virtual patient cases (lumbar, cervical, and thoracic spine pain) simulated by ChatGPT (GPT-4) over 4 weeks, each twice. ChatGPT scored each attempt from 0 to 4 on the same 10 dimensions of the Lasater Clinical Judgment Rubric (LCJR; 0-40 points) that human assessors applied (1-4 per dimension; 10-40 points) during a real patient encounter. Feasibility outcomes were case completion, data completeness, and satisfaction (0-10). Measurement outcomes were internal consistency and convergent validity (Spearman correlations between model-generated and human LCJR scores). Variability estimates informed the sample size of a future trial. Results: All 27 students were assessed with the LCJR; 22 (81%) completed at least 1 LIA case. Both attempts of the lumbar, cervical, and thoracic cases were completed by 78%, 63%, and 74% of students, respectively. Satisfaction data were available for 15 students (56%; mean 6.0, SD 1.3), and missing secondary data clustered in the third rotation. Internal consistency was excellent for the LCJR (alpha=.96) and ranged from .43 to .90 for model-generated ratings. Model-generated LIA scores clustered near the maximum (mean 36.0, SD 1.4). Among completers, LIA scores correlated weakly with the LCJR (rho=0.25, 95% CI -0.20 to 0.61; rho=0.44, 95% CI 0.05-0.71, when noncompleted attempts were scored as 0). Grade point average correlated almost perfectly with the LCJR (rho=0.96; n=22); after adjustment for it, the LIA-LCJR association disappeared (partial rho=-0.10). A future trial would require approximately 39 students per group (80% power, conservative variance). Conclusions: Delivering the LIA within the curriculum was feasible, but clinical judgment ratings generated by ChatGPT did not reflect those of human assessors with a real patient: they clustered near the maximum and showed no convergent validity once noncompletion was separated from performance. LLM-generated ratings should not be used as outcome or assessment measures without validation against human raters. Case calibration, completion tracking, and clarification of the GPA-LCJR relationship are also needed before a definitive trial.

Background: Uncontrolled hypertension frequently persists after emergency department (ED) discharge because of limited education, poor adherence, and fragmented follow-up. This quality improvement initiative evaluated whether structured discharge education plus telephone follow-up could improve blood pressure (BP) and continuity of care. Methods: A prospective, single-center initiative enrolled 50 consecutive adults with uncontrolled hypertension presenting to an ED in Lahore, Pakistan, from May to July 2026. Participants received standardized counseling on medication adherence, lifestyle modification, BP monitoring, warning symptoms, and primary care follow-up, followed by a structured telephone assessment approximately 2 weeks after discharge. We compared pre- and post-intervention BP values among follow-up completers using a paired-samples t-test; we summarized categorical outcomes as frequencies and percentages. Results: Of 50 enrolled patients, 38 (76%) completed follow-up, and 12 (24%) were lost to follow-up. Among completers, mean systolic BP decreased from 165.64 +/- 19.26 to 143.75 +/- 18.52 mmHg and mean diastolic BP decreased from 94.92 +/- 7.86 to 84.88 +/- 7.47 mmHg (P<0.001). Thirty-seven of 38 completers (97.4%; 74% of all enrolled) demonstrated BP improvement, and 19 of 38 (50%; 38% of all enrolled) achieved BP below 140/90 mmHg. Using the conservative all-enrolled denominator, 58% reported medication adherence, 64% reported lifestyle modification, 48% reported primary care follow-up, and 60% reported symptom improvement. Conclusion: Structured discharge education with short-term telephone follow-up was associated with clinically and statistically significant BP reductions and improved self-reported care behaviors. This low-cost approach may strengthen transitions from emergency to primary care in resource-limited settings, although loss to follow-up and the absence of a concurrent control group limit causal inference.

Objective: To examine changes in function and pain interference among patients utilizing a digital exercise therapy application (DETA) for knee and shoulder pain. Methods: We conducted a retrospective analysis of data from patients utilizing a DETA for non-operative knee and shoulder pain. Primary outcomes for the study were 8-week changes in physical function, measured using the PROMIS-Physical Function (knee pain) and PROMIS-Upper Extremity Function (shoulder pain); and pain interference, measured using the PROMIS-Pain Interference. Data on patient characteristics was used to examine outcomes among specific patient subgroups. Results: We observed a 3.5 point (SD: 7.8) increase in function and a 3.9 point (SD: 7.5) decrease in pain interference overall (p<0.001), with changes in function and pain interference surpassing the minimal clinically important difference for patients with knee and shoulder pain. Patients with knee pain experienced greater improvements in function than those with shoulder pain (p=0.02), as did patients who report moderate-high levels of exertion during exercise compared to those reporting low levels of exertion (p=0.05). We saw greater reductions in pain interference among those with higher education (p=0.03), those with more acute symptoms (p=0.01) and those reporting moderate-high levels of exercise exertion (p=0.02). Conclusion: We observed a clinically meaningful improvement in pain interference and function among patients utilizing a DETA for knee and shoulder pain. Patients with knee pain, higher levels of education, more acute symptoms, and those who reported higher levels of exertion with exercise experienced the greatest changes in function and pain. Impact Statement: This study indicates that self-guided interventions, such as those delivered through a DETA, may be beneficial for patients with knee and shoulder pain. These results may also inform the development of patient profiles that can be used to identify patients most appropriate to receive care through a mobile application.

Background: Heat-inactivated postbiotics derived from Lactiplantibacillus plantarum have been proposed to support weight management and metabolic health by acting on the gut-metabolic axis, including endogenous glucagon-like peptide-1 (GLP-1) signaling. resM is an orally delivered formulation combining heat-inactivated L. plantarum RSB11 (RSB11-HI) with vitamin D3, vitamin B12, chromium picolinate, white mulberry (Morus alba) leaf, and fenugreek (Trigonella foenum-graecum) seed extracts. We tested the effects of resM on body weight and a panel of metabolic outcomes in adults with overweight or obesity. Methods: In a randomized, double-blind, placebo-controlled, parallel-group trial (NCT06911073), 80 adults with overweight or obesity were allocated 1:1 to oral resM or matched placebo for 8 weeks. The trial was conducted in a fully remote, direct-to-consumer setting. The primary outcome was absolute change in body weight at the final scheduled weekly assessment, Week 7, corresponding to completion of the 8-week intervention. Secondary outcomes included body-mass index; fasting insulin, HbA1c, and HOMA-IR; serum active GLP-1; strain-specific stool quantitative PCR for L. plantarum RSB11; food cravings measured using the Food Craving Questionnaire-Trait-reduced; depressive symptoms measured using the PHQ-9; safety laboratory measures; and adverse-event surveillance. Between-group differences were evaluated using independent-samples t-tests and baseline-adjusted ANCOVA, and within-group changes were evaluated using paired tests. Results: Body weight decreased by 2.6 kg, or 3.0%, in the resM group and increased by 0.5 kg, or 0.6%, in the placebo group. Food-craving scores fell by 15.1 points within the resM arm during the 8-week intervention (p<0.001), as did depression scores. Active GLP-1 approximately doubled among participants treated with resM and increased more than in the placebo group. Serum GLP-1 levels correlated with L. plantarum RSB11 levels in stool samples in the resM arm. Safety laboratory values remained within reference ranges, gastrointestinal symptoms were reported more frequently with placebo than with resM, and no serious adverse events were reported in either group. Conclusions: Over 8 weeks, resM produced clinically meaningful weight loss within the intervention group and compared with placebo, together with reductions in food cravings and depression scores and an approximately two-fold increase in active GLP-1. Larger and longer-duration trials are needed to confirm the persistence and generalizability of these findings.

Children living with HIV face significant challenges with adherence to daily oral antiretroviral (ARV) treatment due to poor palatability, complicated dosing, and caregiver burden. Long-acting delivery systems designed specifically for children may help overcome these barriers. Microarray patches, also known as microneedle patches, are a needle-free drug delivery technology that could simplify treatment administration and improve adherence. This study explored the acceptability and usability of a pediatric ARV microarray patch prototype among stakeholders in South Africa and Uganda, two countries with a high burden of pediatric HIV. A formative study was conducted in 2024 with 48 participants, including caregivers, community health workers, health care providers, and decision-makers. Data were collected through qualitative methods: interviews, simulated use sessions, and observations. Participants demonstrated high usability of the prototype, with 97% completing all application steps and nearly all reporting the prototype as easy to use and expressing confidence in successful administration. Most participants found the prototypes size, wear time, and temporary skin changes acceptable, and all preferred a weekly patch over daily oral treatment. Applying multiple patches at once to achieve a therapeutic dose was considered feasible. Decision-makers foresaw strong programmatic fit of a pediatric ARV microarray patch if caregivers apply the patch at home following initial facility-based guidance. Overall, the pediatric ARV microarray patch prototype was perceived as highly acceptable and usable across diverse end users, findings that generally align with studies of microarray patches for other use cases (e.g., contraception, HIV pre-exposure prophylaxis, vaccine delivery). The simplicity, comfort, and convenience of a pediatric ARV microarray patch could substantially improve treatment adherence and quality of life for children living with HIV. Further development and clinical evaluation are warranted to advance this promising technology toward real-world use.

Background Obtaining uncontaminated urine samples from children can be difficult. Clean catch urine (CCU) is non-invasive but may be slow and lead to a contaminated sample, whereas transurethral bladder catheterisation (TUBC) and suprapubic aspiration (SPA) are invasive. We assessed the feasibility of randomising children to a definitive trial. Methods FROG was a multicentre, randomised feasibility trial with a mixed-methods perspectives study, health-economic analysis and stakeholder consensus meeting. Children under 16 years requiring urine testing for suspected urinary tract infection (UTI) who could not provide a midstream sample were eligible for the feasibility trial. Parents, children and healthcare professionals were eligible for the perspectives study and consensus meeting. Results Of 703 children screened, 170 were offered the study and 99 were recruited. Overall, 64/170 (37.6%) consented to randomisation, exceeding the feasibility threshold (33%); 32 were allocated to CCU and 32 to TUBC. The allocated method was received by 46/64 (71.9%); delays, unsuccessful collection and distress contributed to non-receipt. Among participants with available cultures, contamination occurred in 2/12 (16.7%) allocated CCU and 0/6 allocated TUBC. No participants consented to randomisation involving SPA. The perspectives study included 14 parent interviews, 89 parent questionnaires and 28 staff across 5 focus groups and 1 interview. CCU and TUBC were considered acceptable, although participants balanced speed and accuracy against pain and distress. SPA availability and acceptability were limited. A total of 19 stakeholders attended the consensus meeting; 94% supported recruiting children aged under 18 months and 100% supported comparing CCU with TUBC, without SPA. Accuracy was the highest-ranked outcome. Conclusions A definitive trial comparing CCU-first with TUBC-first in children aged under 18 months is feasible. Its primary outcomes should reflect diagnostic accuracy and clinical consequences of contamination, with successful collection, collection time, pain and distress assessed as key secondary outcomes.

Background: This study focused on adults with complex care needs due to problems on multiple life domains and consequent high acute care use. The Hotspotters Project was undertaken to assess the effects of proactive integrated care on health outcomes and healthcare costs in this group. We evaluated the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) of the Hotspotters Project in order to identify factors that influenced implementation and outcomes. Method: This mixed method study followed the RE-AIM-framework, using validated questionnaires, routine care data and semi-structured interviews. Qualitative data from patients and care providers offered insight in the quantitative outcomes. Quantitative data were analyzed descriptively (SPSS), and interview transcripts were analyzed using inductive thematic content analysis (Atlas.ti). Results: As acute care use was lower than expected, few patients were eligible (153/1403) and subsequent low enrollment (n=30) limited conclusions regarding effectiveness. Nevertheless, the intervention improved collaboration with social work, and the structured intake was valued for the overview of patients complex needs. Many practices adopted the intervention into regular care, despite the complex inclusion process. Care providers proposed revising the target population and recruitment to better reflect the Dutch context. Conclusion: Although cost-effectiveness could not be assessed, this study nonetheless provides insights that can help future interventions and trials to better match patients needs, adapt to local context and reduce patients study burden. Adapting the definition of patients with complex needs to a local context can strengthen the rationale for implementation and enhance patient motivation.

Background: Fear of falling may limit mobility in older adults, particularly during winter. Pragmatic, community-based interventions are needed to support safe, sustainable walking. Objective: To assess the feasibility and acceptability of a co-created intervention (MABIDA) promoting utilitarian and recreational walking among older adults. Method: Fifty-two older adults with fear of falling participated in a 12-week group intervention (summer/winter) consisting of one 60-minute supervised walking session/week, incorporating exercises. Walking group level was assessed using a subjective decisional tree. Results: Forty-one participants (73.3{+/-}5.7years) completed the study (dropout: winter only). Retention and adherence exceeded 75%. Intervention settings were considered appropriate ([&ge;]81%). The decisional tree correctly classified 72% of participants. Participants reported satisfaction (82%) and enjoyment (81%). No differences were observed between seasons or walking groups (p>0.05). Group walking was the main facilitator (59%), while weather was the main barrier (17%). Conclusion: MABIDA appears feasible, acceptable, and adapted across seasons and walking speed profiles.

Background Hypertension is the leading modifiable risk factor for cardiovascular disease (CVD). Despite availability of blood pressure (BP)-lowering therapies, BP control rates remain suboptimal. Reluctance to initiate treatment with combination therapy and delayed treatment intensification contribute to poor control. Early use of single-pill combinations (SPCs) within standardised treatment protocols (STPs) may improve outcomes, but evidence from India is limited. Objective To evaluate the effectiveness and safety of a new STP incorporating initial or early use of SPCs compared with usual care among adults with hypertension. Methods The New Standardised TrEatment Protocol (NewSTeP) trial is a pragmatic, multicentre, randomized, parallel-group, open-label trial conducted in tertiary healthcare centres in India. Adults with hypertension who are untreated or receiving one BP-lowering drug and require treatment initiation or intensification (n = 300) will be randomized 1:1 to either a new STP incorporating early SPC therapy or usual care. Participants will be followed for 6 months. The primary effectiveness outcome is change in home-measured mean systolic BP from randomization to month 6. The primary safety outcome is discontinuation of trial drug due to adverse events. Secondary outcomes include proportion of participants achieving BP control, change in diastolic BP, incidence of adverse events of special interest, treatment adherence, treatment modification, and time to BP control. A process evaluation will assess reach, implementation, acceptability, and sustainability, while an economic evaluation will assess cost-effectiveness of the intervention. Results Between October 2025 and March 2026, 300 participants were randomized across nine sites (150 to New STP; 150 usual care) from 360 screened individuals. Final follow-up is expected in September 2026, with results anticipated in October 2026. Conclusions The NewSTeP trial will provide evidence on the effectiveness, safety, implementation, and cost-effectiveness of an SPC-based STP for hypertension management in India and inform future hypertension control strategies and policies.

Purpose: To co-design a community-based walking program that incorporates social connection to improve physical activity post-stroke. Methods: A four-stage Integrated Knowledge Translation approach was used. Stage 1: research team (2 stroke survivors, 8 professionals) defined research questions, scope and plan. Stage 2: workshops held with stroke survivors, carers, and health and design professionals to identify important program principles. Stage 3: research team used a Nominal Group Technique to make key decisions and develop the program. Stage 4: program presented to participants; feedback gathered and adaptations made. Workshop findings were iteratively analysed and summarised during sessions. Results: Twenty-six participants were recruited across stages 2 and 4 (12 stroke survivors, 2 carers, 12 professionals). Key program principles identified in Stage 2 were social support, inclusive environment, motivational support, co-ordination and administrative support. The Supportive Strides program was co-designed to incorporate these principles. Program elements included accessible outdoor walking routes, pre-walk coffee and social connection, peer-support, online group chat, milestone celebrations, and a safety checklist. Following Stage 4 participant feedback, adaptations were incorporated e.g., simpler screening process, include more walking route information. Conclusions: The co-designed Supportive Strides community-based walking program is ready for testing to improve physical activity and social connection after stroke.

Background: Diabetes is a major global public health challenge, associated with substantial medical, economic, and social burden worldwide. As clinicians working at the intersection of medicine and nutrition, we observed that despite advances in pharmacologic therapy, many individual, particularly those living in underserved urban communitie, continue to experience suboptimal diabetes control due to persistent barriers related to food insecurity, cultural food practices, and limited access to practical nutrition education. In response, we implemented a community-based pilot study in an underserved urban area that focused on dietitian-led nutrition education grounded in Food Is Medicine principles. Aims: The intervention emphasized culturally responsive, cost-conscious, and client-centred approaches designed to make healthy eating simple and intuitive, with the goal of complementing standard diabetic medical therapy. Methods: We used conventional diabetic marker responses, fasting blood sugar (FBS), HgbA1c (percentage of glycosylated hemoglobin, subsequently documented as A1c), and urinary albumin:creatinine ratio (UACR) in a dual cohort design study measuring whether groups receiving dietitian-led nutrition education in addition to conventional therapy would show improvements in diabetic markers relative to groups receiving conventional therapy alone. Summary: Our pilot study summed over both cohorts support the hypothesis that additional dietitian-led nutrition education synergizes with conventional pharmaceutical therapy to improve diabetic control as gauged by improved FBS, A1c and UACR, implying a significant role for this combined approach to community based diabetic health care.

Background: School-based implementation of robot-assisted walking may support increased physical and social participation for children with physical disabilities, but evidence from an adequately powered trial is needed. This pilot study evaluated implementation strategies and study procedures to inform a future definitive trial. Methods: Participants were randomized to 12-weeks of robot-assisted walking or control, with subsequent crossover to the other condition. In the intervention arm, targeted dose was 75 minutes of robot-assisted walking, spread across three days/week. Implementation strategies for the child's classroom team included educational materials, centralized technical assistance, school champions, and on-going training. Implementation strategy evaluation focused on intervention protocol feasibility (i.e., weekly device use, troubleshooting) and fidelity (documentation of implementation strategy modifications). Preliminary estimates participation goal changes were obtained using the Canadian Occupational Performance Measure (COPM) 'Performance' scale (/10). Results: Eight children with neurodevelopmental physical disabilities participated (mean age 3.5, SD 0.5 years). Device use varied from 2.1 to 4.3 days/week (median 3.3) with a range of 48 to 96 minutes/week (median 80). Target use of >= 3 days/week was achieved for 66% of weeks and met the >=75-minute target for 33% of weeks. Troubleshooting occurred in 18.5% of sessions. Two implementation strategies were modified to improve feasibility. COPM mean change was 3.56 (SD 1.07) for robot-assisted walking and 2.11 (SD 2.41) for control (dz=0.74). Conclusions: This pilot study provided preliminary evidence regarding both the feasibility of robot-assisted walking implementation in schools and its potential effectiveness for children with physical disabilities. Findings support progression to a definitive trial.

Abstract Background: Randomized trials show substantial weight loss with semaglutide and tirzepatide under structured care, but little is known about whether patients in routine practice continue therapy, reach a maintenance dose, and have their weight measured. Objectives: To describe the first year after initiation of semaglutide or tirzepatide for obesity, including care patterns, maintenance-dose attainment, weight documentation, and total body weight loss (TBWL). Methods: This retrospective cohort study used Epic Cosmos, an electronic health record network of >350 US health systems, to identify adults with obesity and without diabetes who initiated injectable semaglutide or tirzepatide in 2024. Outcomes over 12 months included prescribing persistence, discontinuation, switching, add-on therapy, and reinitiation; attainment of Food and Drug Administration (FDA)-labeled maintenance doses; availability of follow-up weight; and TBWL across progressively restricted populations. Results: Among 743,153 adults (60.1% semaglutide; mean age, 48.5 years; 72.5% female), 12-month prescribing persistence was 29.9% for semaglutide and 35.9% for tirzepatide. FDA-labeled maintenance-dose attainment was 28.3% and 55.0%, respectively, and only 8.8% and 16.4% remained prescribing persistent at a maintenance dose with a recorded weight at 12 months. About half of initiators lacked a 12-month weight. Among all initiators, [&ge;]5% TBWL was documented in 25.6% (semaglutide) and 30.4% (tirzepatide), rising to 51.9% and 61.9% among those with recorded weight, 66.1% and 79.5% among those also prescribing persistent, and 82.9% and 87.3% among those further at a maintenance dose. Conclusions: In routine practice, most patients initiating semaglutide or tirzepatide did not remain on therapy, reach a maintenance dose, and have weight documented through the first year. Documented weight loss was greatest among those completing each step of care, suggesting continuation, dose escalation, and monitoring as targets for improvement.
