In Vitro and In Vivo Comparison of a Novel Antimicrobial Wound Hydrogel With Commercial Wound Treatments: Antimicrobial, Antibiofilm and Biocompatibility Assessment

ABSTRACT

Antimicrobial resistance (AMR) and biofilm formation significantly hinder chronic wound management, necessitating safer and more effective therapeutic options. This study evaluates the antimicrobial, antibiofilm, cytocompatibility and anti-inflammatory properties of a novel antimicrobial hydrogel Formulation (#1) compared with commercially available wound hydrogel and cream Formulations (#2–5). Antimicrobial activity was assessed using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays against Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, and mixed-species cultures. Biofilm-related efficacy was evaluated via crystal violet (CV) staining and minimum biofilm inhibitory concentration (MBIC) assays. Cytotoxicity was examined using ISO-compliant MTT and confluency assays on L929 fibroblasts. In vivo anti-inflammatory effects were assessed using intra-cutaneous injection in New Zealand White rabbits with histological evaluation per ISO 10993-23. Formulation 1 showed the lowest MIC and MBC values across all pathogens, including polymicrobial cultures, indicating strong broad-spectrum efficacy. In biofilm assays, it reduced biofilm biomass by 50%–60% within 10 min and prevented new formation at lower MBIC values than Formulation 2, especially in mixed-species models. Cytotoxicity testing confirmed Formulation 1 maintained ≥ 81% cell viability across all concentrations, outperforming other products and meeting ISO and USP safety thresholds. In vivo, both Formulation 1 and 2 induced minimal inflammation, with Formulation 1 showing slightly milder tissue responses. Formulation 1 demonstrated strong antimicrobial efficacy, reliable biofilm control, and favourable cytocompatibility compared with the comparator formulations tested in this study. These findings support further evaluation of this formulation for chronic wounds complicated by biofilms and antimicrobial resistance.

Factors affecting implementation of hospital inpatient-level care at home: a qualitative study of virtual wards in North West England

Por: Bradley · F. · Howells · K. · Gasteiger · N. · Sanders · C. · Blakeman · T. · Dowding · D.
Objectives

To identify key factors influencing the implementation of technology-enabled virtual wards (VWs), also known as hospital at home, drawing on the qualitative accounts of stakeholders involved in implementation, using the updated Consolidated Framework for Implementation Research (CFIR) as a guiding analytical framework.

Design

Qualitative semi-structured interviews with implementation leads. All interviews were conducted online, using MS Teams or Zoom, between January–June 2024, and audio-recorded with consent. Audio-recordings were transcribed, anonymised and exported to NVivo V.12 Pro software for data management. The updated CFIR was used to guide thematic analysis of interview data.

Setting

Adult VW services in one regional health and social care system in North West England, UK.

Participants

Service implementation leads from 11 hospital sites providing adult VW services. Job titles and roles varied across sites and included both operational and clinical service leads.

Results

20 interviews were conducted with 22 participants. Four implementation themes were identified: (1) complexity and adaptability: the ability to adapt the service to local conditions was valued by leads, but also contributed to wide variation in operational, clinical, workforce and digital components of VW models; (2) resource and infrastructure: workforce capacity was identified as a key implementation challenge along with information technology system capability and interoperability; (3) performance demands: leads were concerned that an excessive focus on bed numbers and occupancy levels, without accounting for patient acuity, could negatively affect implementation, straining the service and staff capacity; and (4) readiness for change: organisational and professional readiness for change was considered crucial for increasing referrals and enabling successful implementation, yet leads reported that the level of behavioural and cultural change required had been underestimated.

Conclusions

Implementation of a national VWs programme has resulted in wide service variation in one UK region, which raises questions about service equity and poses challenges for wider programme evaluation. Despite this variation, common factors found to help or hinder implementation have been identified. This study provides greater understanding of the factors that influence the implementation of VW services and outlines actionable insights to help refine VW strategies. These insights can support future planning and sustainability of technology-enabled inpatient-level care at home more widely.

Arts-based empathy education in healthcare: a critical systematic review of pedagogical mechanisms and evidence gaps

Por: Mojarrad · S. · Khojasteh · L. · Soori · A.
Objectives

To systematically identify and synthesise the pedagogical mechanisms through which arts-based interventions (theatre, poetry, narrative medicine) may support empathy development in healthcare learners, while critically appraising the contextual implementation factors and methodological limitations of the existing evidence base.

Design

Systematic review with narrative synthesis, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Data sources

MEDLINE (via PubMed), Embase, PsycINFO, ERIC, Cochrane Central Register of Controlled Trials, Web of Science Core Collection and CINAHL Plus, from inception to 31 August 2025.

Eligibility criteria for selecting studies

Peer-reviewed empirical studies involving undergraduate or postgraduate healthcare students or professionals. Eligible studies reported on arts-based educational interventions designed to enhance empathy (including theatre, poetry or narrative medicine) and included quantitative or qualitative outcome measures of empathy or related constructs. No restrictions were placed on study design.

Data extraction and synthesis

Two reviewers independently screened records, extracted data on intervention characteristics and outcomes, and assessed methodological quality using the Medical Education Research Study Quality Instrument and Critical Appraisal Skills Programme tools. A narrative synthesis was conducted to examine patterns across intervention modalities. Effect sizes (Cohen’s d) were calculated for quantitative pre-post or controlled designs; meta-analysis was precluded due to high heterogeneity in study designs, populations and outcome measures.

Results

From 1094 records screened, 17 studies involving 835 participants (median sample size=28) met inclusion criteria. There were eight theatre-based, five poetry-based and four narrative medicine interventions. Theatre interventions, which emphasised embodied learning, showed patterns of large empathy effects (mean d=0.83). Poetry interventions, focusing on reflective practice, showed patterns of moderate effects (mean d=0.49). One study of narrative medicine demonstrated a pattern of sustained gains at 2-year follow-up (d=0.82). Key limitations of the evidence base include small sample sizes, substantial measurement heterogeneity (12 different empathy instruments), geographical bias (88% of studies from high-income, Western countries), and a predominance of pre–post study designs.

Conclusions

Arts-based interventions show mechanism-specific patterns of potential benefit for empathy in healthcare learners. However, significant methodological limitations in the current evidence constrain definitive practice recommendations. Educators may consider piloting brief, facilitator-led interventions based on local resources, while acknowledging the need for more robust evidence. Future research must prioritise standardised outcome measures, rigorous controlled and longitudinal trial designs, and studies in diverse cultural contexts.

Academic workload and lifestyle predict emotional well-being among university students in the United Arab Emirates: A cross-sectional study

by Munawar Farooq, Uffaira Hafeez, Amir Ahmad, Susan Waller, Gabriel Andrade, Arif Alper Cevik, Syed Fahad Javaid

Background

Stress is a prevalent issue among university students and is linked to adverse academic and emotional outcomes. While research emphasizes the roles of resilience, personality traits, and psychosocial factors, most studies are drawn from North American and European contexts.

Objectives

This is the first study of its kind in the United Arab Emirates (UAE) exploring the relationship between perceived stress, resilience, and personality traits among university students, offering insights into region-specific influences on emotional well-being.

Methods

An online cross-sectional survey was conducted among 168 students from two colleges at the United Arab Emirates University (79% College of Medicine and Health Sciences, 21% College of Information Technology; 72% female). Data were analyzed using descriptive statistics and regression models in R version 4.2.0. Personality traits were assessed using the Ten-Item Personality Inventory, perceived stress was measured with the Perceived Stress Scale, and resilience was evaluated with the Brief Resilience Scale.

Results

The median perceived stress score was 22 (IQR: 17–28), and 30% reported high stress. Multivariable analysis showed that heavier academic workload, financial difficulties, lack of social support, lower physical activity, and poorer academic performance significantly predicted higher perceived stress, whereas resilience and emotional stability were protective.

Conclusion

University students’ perceived stress is closely associated with modifiable factors, including academic workload, social support, resilience, and physical activity. Targeted interventions, such as resilience training, promoting physical activity, optimizing academic schedules, and strengthening support services, are vital to reducing perceived stress and enhancing student well-being.

Rhinovirus/enterovirus contribution to respiratory-associated hospitalizations in adults during respiratory seasons in Spain: A 6-year prospective study

by Sandra S. Chaves, Valérie Bosch Castells, Ainara Mira-Iglesias, Joan Puig-Barberà, F. Xavier López-Labrador, Miguel Tortajada-Girbés, Mario Carballido-Fernández, Joan Mollar-Maseres, Germán Schwarz-Chávarri, Javier Díez-Domingo, Alejandro Orrico-Sánchez, Valencia Hospital Network for the Study of Influenza and other Respiratory Viruses (VAHNSI)

Background

Understanding the burden of acute viral respiratory infection-related hospitalizations is crucial for guiding research and development. Unlike influenza, respiratory syncytial virus (RSV), or severe acute respiratory syndrome coronavirus 2, no pharmaceutical interventions exist for other respiratory viruses; therefore, their impact remains poorly characterized. This study aimed to investigate the association of current non-vaccine-preventable respiratory viruses, especially rhinovirus/enterovirus (RV/EV), on hospitalizations during the respiratory seasons.

Methods

Data from a prospective study that used multiplex polymerase chain reaction to conduct long-term surveillance on respiratory viruses in Valencia, Spain were analyzed. Patients aged ≥50 years hospitalized due to respiratory illness from 2014–15–2019–20 were included.

Results

Respiratory viruses were detected in 35.2% (3,755/10,675) of hospitalized patients with acute respiratory illness. Influenza and RSV accounted for 22.1% of hospitalizations, RV/EV for 7.6%, and other non-vaccine-preventable viruses for 5.4%. Adults ≥75 years had average seasonal hospitalization incidence rates more than twice those aged 65–74 years and eight times those aged 50–64-year-olds. No significant differences in severity markers were observed among patients with or without virus identified, those aged ≥75 years had a 2–3 times higher mortality rate compared to younger age groups.

Conclusions

The potential impact of respiratory viruses on hospitalization rates among older adults, particularly those aged ≥75 years, highlights the need for targeted interventions to reduce healthcare system burden. Enhanced diagnostic capabilities and the development of next-generation preventive strategies, including vaccines and therapeutics, could improve patient outcomes and strengthen the resilience of the healthcare system during respiratory virus seasons.

Development and Psychometric Evaluation of a Medical Device–Related Pressure Injury Risk Assessment Scale

ABSTRACT

Medical device–related pressure injuries are a significant and largely preventable patient safety problem, yet existing pressure injury risk scales do not adequately capture device-specific risk factors in adults. This methodological study developed and psychometrically evaluated a standardized risk assessment scale to identify medical device–related pressure injury risk in hospitalized adult patients. An initial item pool was generated from an extensive literature review and clinical expertise, and content validity was assessed by seven experts using the Davis technique (content validity index = 0.96). The scale was administered to 160 adults receiving at least one medical device in medical, surgical and oncology wards and intensive care units of a university hospital. Construct validity was evaluated using binary logistic regression, exploratory factor analysis, and receiver operating characteristic curve analysis, demonstrating strong discrimination (area under the curve = 0.844, 95% confidence interval 0.728–0.961) with an optimal cut-off score of 14.5 (sensitivity 70.6%, specificity 88.8%). Exploratory factor analysis of the final version of the MedRAS (Kaiser-Meyer-Olkin = 0.792) revealed a two-factor structure (Device and Mechanical Factors; Patient and Tissue Factors) explaining 50.92% of the total variance, with all factor loadings above 0.30. The scale showed good internal consistency (Cronbach's alpha = 0.80) and very good inter-rater reliability (Cohen's kappa = 0.806, p < 0.001). This device-focused scale may support early risk identification and targeted preventive nursing interventions, with potential to improve patient safety and quality of care in inpatient/critical care settings.

Identification and detection of genetic markers associated with antimicrobial susceptibility and evaluation of efflux pump mechanisms in <i>Mycoplasma iowae</i>

by Dominika Buni, Áron Botond Kovács, Enikő Wehmann, Dénes Grózner, Krisztián Bányai, Eszter Zsófia Nagy, Janet Bradbury, Marco Bottinelli, Elisabetta Stefani, Salvatore Catania, Inna Lysnyansky, László Kovács, Miklós Gyuranecz, Zsuzsa Kreizinger

Mycoplasma iowae is an economically significant pathogen that causes reduced hatchability, late embryo mortality and leg deformities, chondrodystrophy and skeletal lesions in poults. While prevention is essential in the control of infection, the appropriate administration of antibiotics may reduce economic losses during outbreaks. As a first step in the exploration of antimicrobial resistance mechanisms in M. iowae, target modification and efflux pump activity were examined in the present study. Point mutations were analyzed in previously described antibiotic binding sites in the whole genome sequences of 99 M. iowae strains. Mismatch amplification mutation assays (MAMAs) were designed and validated for the differentiation of mutations corresponding to elevated minimum inhibitory concentration (MIC) values for fluoroquinolones. Broth microdilution assays were performed to evaluate the effect of efflux pump inhibitors. In the presence of orthovanadate (OV), MIC values were significantly lower than in the absence of OV for spiramycin, tilmicosin, tylosin and oxytetracycline, which may indicate the presence of an active efflux system in M. iowae. Putative promoter regions of efflux-related genes were predicted and characterized. Genetic mutations, previously described in other bacteria, were described to be associated with elevated fluoroquinolone, macrolide and lincomycin MICs in M. iowae, although certain resistant phenotypes remained unexplained, promoting future examinations for deeper insights. The developed MAMAs may support rapid identification of M. iowae strains with elevated MIC values for fluoroquinolones. The better understanding of the efflux pump mechanisms enables the development of alternative methods for the support of therapy against this pathogen.

Clinician factors influencing decision-making in emergency general surgery (EGS): a scoping review protocol

Por: Groundwater · E. · Bisset · C. N. · Bradley · R. · John-Charles · R. · Maeda · Y. · McKee · T. · Moug · S. J.
Introduction

Emergency general surgery (EGS) decisions often occur under time pressure and with reduced patient involvement in comparison to the elective setting. Variation in decision-making in the field of EGS is partly attributable to patient and contextual factors, but clinician factors also likely shape decisions.

This scoping review aims to clarify which clinician factors have been investigated in relation to decision-making in adult EGS, which have been identified as influential, and the methods used to measure them.

Methods and analysis

Any studies reporting on individual clinician factors and decision-making in EGS will be eligible. Studies must be only in adult populations (patients aged 18 and over). This review will consider quantitative, qualitative and mixed-methods study designs.

This scoping review will be conducted in accordance with the methodology developed by the Joanna Briggs Institute and reported in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. This protocol was prospectively registered with the Open Science Framework: https://osf.io/xcqp4. We will search MEDLINE, EMBASE, CINAHL, CDSR and CENTRAL. The search strategy will be adapted for each database, and no time or language restrictions will be applied.

Two independent reviewers will screen studies for eligibility and extract data using a purpose-designed data extraction form, with disagreements resolved by a third reviewer. Extracted data will be synthesised using a narrative approach to map key concepts, describe study characteristics and identify gaps in the literature.

Ethics and dissemination

Ethical approval is not required as this review will use publicly available data. Findings will be disseminated through peer-reviewed publication and conference presentations.

Life expectancy gains across US states between 1941 and 2000: a cohort study

Por: Pifarre i Arolas · H. · Andrade · J. · Fletcher · J.
Objectives

We use new data and robust methods to estimate mortality levels and trends for US states and Washington DC and quantify cohort life expectancy for birth cohorts between 1941 and 2000.

Design

Observational retrospective cohort study.

Data

Mortality data and population estimates for cohorts born between 1941 and 2000 at the state, regional and national levels were obtained from the US Mortality Database.

Main outcome measures

We estimated cohort life expectancy at birth by sex and geographical level. We used the coefficient of variation to assess levels and trends in convergence in cohort life expectancy by geographical level.

Results

In contrast to recent findings, estimates suggest that all states and regions experienced cohort life expectancy gains between the birth cohorts of 1941 and 2000 for both sexes, typically more than 5 years; the range included gains of 7–8 years in Oklahoma and Arkansas to over 14 years in Arizona, New Mexico and South Carolina (men). States sharply converged in the 1940s due to the South making substantial gains in under-five mortality, and since the 1960s there has been overall stability in geographical variation that is a combination of continued convergence by the South and modest divergence in the Midwest.

Conclusions

Cohort life expectancy estimates across US states over the birth cohorts born between 1941 and 2000 have shown important gains in all states and regions. The lack of progress estimated in other work is not replicated; for example, recent work estimated that between 1950 and 2000, at least 15 states’ female populations experienced cohort life expectancy losses; however, the use of better data and robust methods show no losses by any state. Our results also point to early life public health and medical interventions as key explanations for regional convergence in cohort life expectancy around 1950, however, the results suggest only modest additional convergence since then.

Depression Beyond the 6‐Month Postpartum Period: A Mixed‐Method Study Among Women in Nepal

ABSTRACT

Aim

This study aimed to comprehensively examine social and clinical factors contributing to postpartum depression among women in Nepal and identify their perspectives/experiences regarding postpartum mental health.

Design and Methods

The explanatory sequential mixed-method study was conducted in two phases. In the quantitative phase, data were collected via survey of 200 postpartum women at immunisation clinics of two hospitals in Kathmandu Nepal. Measures included sociodemographic and perinatal factors and the Edinburgh Postpartum Depression Scale. Regression models were conducted to analyse data. In the qualitative phase, in-depth interviews were conducted with 15 participants having depression scores ≥ 10. Data were analysed using the thematic content analysis method. Qualitative and quantitative findings were integrated using the joint display and the narrative weaving approach to generate results.

Results

Findings show that 28% of postpartum women screened positive for depressive symptoms, requiring referral for further evaluation. Integrated findings indicate that prenatal mental health problems, low birth weight or medical conditions among infants, intimate partner violence, partner substance abuse, and a lack of postpartum social support were major contributors to postpartum depression.

Conclusion

Depression is highly prevalent among women 6–12 months postpartum in Nepal and is associated with several clinical and social factors.

Implications

These findings have important implications, emphasising the need for routine screening using validated tools for early identification, timely treatment and referral of women at-risk for postpartum depression. Evidence-based clinical and community initiatives are needed to promote positive outcomes for women and their families.

Patient or Public Contribution

External experts were consulted for survey questions and qualitative interview guide, then refined those instruments based on their feedback to improve construct validity. The immunisation clinic staff provided input during study design, for participant recruitment and data collection. Key findings were presented to stakeholders to validate the interpretation of findings.

Body Mass Index: A Key Factor in Surgical Site Infections After Kidney Transplantation?

ABSTRACT

Kidney transplant recipients are at increased risk of surgical site infections (SSIs) due to procedural complexity and immunosuppression. This retrospective single-centre study examines the influence of BMI on SSI risk and identifies common pathogens. A total of 230 renal transplant patients were included in this analysis 2017 and 2019. All patients received a cephalosporin for prophylaxis, and wound swabs were taken from those who developed SSIs. SSIs occurred in 45 patients (19.6%) and were not significantly associated with age, sex or donor type. The most common organisms were coagulase-negative staphylococci (26.7%), Staphylococcus epidermidis (24.4%), Enterococcus faecalis (22.2%) and Candida albicans (22.2%). SSIs were significantly linked to surgical revision (p < 0.001) and higher BMI (p = 0.027). A BMI ≥ 28.1 was associated with threefold higher odds of SSIs (OR = 3.0; p = 0.001). Each one-unit increase in BMI was associated with a 7.2% increase in the odds of SSI occurrence (OR = 1.072; p = 0.020). Staphylococcus (p = 0.019) and Enterococcus (p = 0.048) infections were more common in patients with BMI > 28.1. Therefore, SSIs are a frequent complication posttransplant and are strongly associated with high BMI. Standard antibiotic regimens may not cover all relevant pathogens in obese patients, underscoring the need for tailored prophylactic strategies.

Early Prediction of Scar Outcomes: A Prospective Study on the Predictive Value of 3‐Month Scar Assessments for 12‐Month Results

ABSTRACT

Scar outcomes are traditionally evaluated at 12 months post-surgery, yet early prediction of long-term scar characteristics may facilitate timely interventions, enhance treatment strategies, shorten clinical trial durations, and improve patient outcomes. This study evaluates whether 3-month scar assessments reliably predict 12-month outcomes using validated scar assessment scales and interrater reliability measures. Two surgeons evaluated a prospective cohort of 40 surgical patients using standardised scar assessment tools. Logistic regression assessed the predictive value of 3-month classifications for 12-month binary outcomes (‘good’ vs. ‘poor’ scar quality), while linear regression evaluated continuous scar scores. Receiver operating characteristic (ROC) curves and area under the curve (AUC) values quantified predictive accuracy. Scars classified as ‘good’ at 3 months were significantly more likely to remain ‘good’ at 12 months (p < 0.001), with strong predictive performance (AUC = 0.763). Linear regression demonstrated significant predictive accuracy for width, height, and overall opinion. However, vascularity predictions were weak, and depth was not significantly associated with long-term outcomes. Interrater reliability was moderate to good across measures, with intraclass correlation coefficients values ranging from 0.215 (depth) to 0.714 (width), and Cohen's Kappa for binary scar classifications of 0.505 (p < 0.001). Early 3-month scar assessments reliably predict 12-month outcomes for width, height, and overall opinion, while vascularity and depth remain less predictable. Scars rated as ‘good’ at 3 months are unlikely to worsen, while ‘poor’ scars rarely improve without intervention. These findings highlight the utility of early scar evaluations in guiding postoperative management and patient counselling.

First population-based study on non-communicable diseases and risk factors in northeastern Iran: Sabzevar cohort profile

Por: Ghorat · F. · Chaman · R. · Javadinia · S. A. · Rad · M. · Mohammadzadeh · M. · Hassanpour · K. · Foroumandi · E. · Nazarzadeh · M. · Saghi · M. H. · Salari · M. · Bidel · Z. · Eghtesad · S. · Gohari · A. · Mohammadi · Z. · Borghabani · R. · Ghorbani · M. M. · Moslem · A. · Norouzi · S.
Purpose

Non-communicable diseases (NCDs) have become the leading cause of mortality globally, with a sharp rise in Iran due to lifestyle changes and urbanisation. Although many NCD risk factors are modifiable, limited understanding of their determinants hinders effective prevention. To address this, the Prospective Epidemiological Research Studies in Iran (PERSIAN) Cohort was established in 2014 to study NCDs nationwide. The Sabzevar PERSIAN Cohort Study (SPECS) is the first in northeastern Iran, aiming to investigate environmental and social factors influencing NCDs in a unique regional context.

Participants

SPECS enrolled 5174 adults (aged 35–70 years) in northeastern Iran between January 2018 and January 2019 through a census and an online registration process. The baseline data collection included demographic verification, informed consent, health questionnaires, anthropometric measurements and biological samples (blood, urine, hair, nails). The annual follow-up began in April 2019, with full reassessments every 5 years over a 15-year period. The data is gathered via an active and passive follow-up, supported by trained staff and registry linkages.

Findings to date

Of the 5174 participants, 4241 (81%) remained in the study. Among the cohort, 54.5% were female, with a mean age of 50.5 years. The majority were married (93.5%), and nearly half had at least high-school education (46.5%) and moderate socioeconomic status (49.4%). Drug abuse history (smoking/drugs) was reported by about 15% of the sample. The mean body mass index was 26.9 kg/m², and the average blood pressure was higher in males (118.1/74.0 mm Hg) than in females (111.5/70.2 mm Hg). The common conditions included hypertension (22.8%), kidney stones (22.4%), fatty liver (15.4%) and diabetes (13.8%). Cancer had the highest treatment rate (100%), while fatty liver had the lowest (70.1%). Stroke had the highest mean age of onset (51.2 years), and epilepsy the lowest (23.7 years). All health data were self-reported.

Future plans

SPECS, part of the national PERSIAN cohort initiative, is the only adult NCD-focused study in Khorasan Razavi. Its 15-year follow-up aims to generate region-specific insights into the incidence of NCDs and their risk factors. The ethnically homogeneous sample enhances statistical power, and the findings may inform culturally tailored health policies. While self-reported data have limitations due to bias, high initial participation and access to free healthcare support long-term engagement, especially among lower-income groups.

Perceptions of patients with heart failure guide an understanding of initial enrolment and long-term adherence to a home-based, non-aerobic, gentle exercise programme

Por: Gould · K. A. · Bowen Brady · H. M.

Commentary on: Platz K, Metzger M, Cavanagh C, et al. Initiating and continuing long-term exercise in heart failure: A qualitative analysis from the GEtting iNTo Light Exercise-Heart Failure Study.

Implications for practice and research

  • When clinicians have a better understanding of patient decisions regarding exercise, they are better equipped to redesign traditional cardiac exercise programmes.

  • Themes from this study provide frameworks to design future quantitative and mixed-method studies that will inform clinicians about the patient experience with cardiac exercise programmes.

  • Context

    Management of heart failure (HF) is a challenge, with less than one-third of patients meeting physical activity recommendations.1 Existing cardiac rehabilitation programmes are designed to meet class 1A American Heart Association recommendations for physical activity.1 Benefits, facilitators and barriers to these programmes are described...

    An interdisciplinary rehabilitation program for adults with dementia—A randomized controlled pilot trial evaluating social participation, loneliness and mental health

    by Josefine Lampinen, Håkan Littbrand, Ingeborg Nilsson, Annika Toots, Yngve Gustafson, Jerry Öhlin, Henrik Holmberg, Birgitta Olofsson, Anita Ericsson, Mia Conradsson

    Background

    To meet the complex needs of adults with dementia, a team-based, individualized rehabilitation approach may be required. This randomized controlled pilot trial evaluated the feasibility of a person-centred multidimensional interdisciplinary rehabilitation program for older adults with dementia, in terms of follow-up and response rates, and potential short- and long-term effects in adults with dementia on social participation, loneliness, and mental health.

    Methods

    Participants (mean age (SD) 78.7 (±6.6) years), were randomized to an intervention group (n = 31) or usual care (n = 30). The rehabilitation program consisted of a 20-week rehabilitation period and two follow-ups after 5 and 14 months. An interdisciplinary team performed assessments and interventions based on the individual’s goals. Assessors blinded to group allocation performed structured assessments at baseline and after 5, 12, 24, and 36 months.

    Results

    Initially, response rates in participants with dementia were high for all assessments in the areas of social participation, loneliness, and mental health. Response rates after 12 months decreased, particularly for cognitively demanding questions with multiple-choice options in the area of social participation. Overall, there were few statistically significant differences between the groups in the outcomes over 36 months, but some of the findings seemed potentially clinically meaningful in favor of the intervention group: increased frequency of active recreation and organized social activities outside the home, as reported by both participants with dementia and caregivers or staff; as well as experienced more frequent visits to family and friends; and short-term reduction in depressive symptoms.

    Conclusions

    Assessments made of loneliness and mental health in this study over three years seemed feasible. It seemed cognitively demanding for participants with dementia to answer questions regarding social participation over time; therefore it seemed worthwhile to also ask informal caregivers or staff to avoid data loss. The positive findings noted during assessments and potential effects indicate that it is relevant to proceed further to an adequately powered RCT and conducted in additional geographical regions.

    Measurement of heart rate and respiratory rate using remote photoplethysmography in paediatrics: a prospective comparative trial protocol - 'rMonitoped1

    Por: Haas-Ferrua · S. · Giaccardi · H. · Ancey · B. · Freyssinet · E. · Baranton · E. · Joulie · A. · Bendimerad · I. · Olla · M. · De Oliveira · F. · Moussaoui · A. · Boyer · L. · Fontas · E. · Tran · A.
    Introduction

    Vital signs such as heart rate (HR) and respiratory rate (RR), crucial for clinical assessment, are often challenging to measure in paediatric populations. Remote photoplethysmography (rPPG), a video-based measurement tool, has demonstrated accuracy in adults. The objective of this study is to compare HR and RR measurements obtained using rPPG with those from standard clinical monitoring in a paediatric population.

    Methods and analysis

    This is a monocentric, prospective study enrolling 600 paediatric participants. Each participant will have standard monitoring electrodes (ECG/impedance) placed on the chest while seated facing a camera for rPPG recording. Simultaneous HR and RR measurements will be recorded over periods of 30 and 60 s using both the standard monitor and the rPPG device. The intraclass correlation coefficient will be calculated to assess agreement between the rPPG and standard monitor measurements.

    Ethics and dissemination

    The study protocol has been approved by the French Agency for the Safety of Health Products (ANSM (Agence nationale de sécurité du médicament) registration no. IDRCB 2023-A02524-41) and by a French ethics committee (CPP Sud Méditerranée III at 29 August 2024, n°2024-A01324-43). The study’s findings will be published in peer-reviewed journals and disseminated at national and international conferences and through press releases.

    Objectives

    Cancer in adolescents and young adults (AYAs; ages 15–39 years) is a rising global epidemic. Yet, AYAs remain an understudied population, and little is known about what research topics should be prioritised according to those with lived experience. The AYA Cancer Priority Setting Partnership (PSP) was established to identify the top 10 research priorities for AYA cancer in Canada according to patients, caregivers, and clinicians.

    This project followed the James Lind Alliance (JLA) Priority Setting Partnership (PSP) methodology that included two national cross-sectional surveys and a final priority setting workshop following an adapted nominal group technique.

    Setting

    A national sample was recruited to participate from across Canada.

    Participants

    Participants were patients, caregivers, and clinicians with lived personal and/or professional experience of AYA cancer in Canada.

    Outcome measures

    In the first survey, open-ended responses were collected from participants about questions they would like answered by research. Responses were collated into overarching summary questions and a literature search was undertaken to verify if questions were true uncertainties and not fully answered by existing evidence. Unanswered questions were ranked by participants in a second survey. The top-ranked questions were prioritised through consensus at the final priority setting workshop. The final outcome was the top 10 priorities for AYA cancer research in Canada.

    Results

    In the initial survey, 1916 potential research questions were submitted by 275 patients, caregivers, and clinicians. Following data processing, summary question formation, and the evidence check, 58 questions were put forward for interim prioritisation in a second survey (n=285 patients, caregivers, and clinicians). The top 20 questions from the interim prioritisation were ranked at the final priority setting workshop attended by a diverse group of 23 patients, caregivers and clinicians from across Canada. The resulting top 10 priorities reflect topics across the cancer continuum including: diagnostic delays, screening and early detection, novel therapies, psychosocial impacts, end-of-life concerns, and survivorship issues.

    Conclusions

    This patient-directed research agenda will guide researchers, funding agencies, and policymakers to ensure that future research is aligned with what matters most to the AYA cancer community.

    Objective

    To explore the perceptions, challenges and strategies of caregivers in managing screen time among children younger than 5 years in the urban and rural areas of Tamil Nadu, India.

    Design

    Qualitative study using focus group discussions (FGDs).

    Setting

    Rural Health and Training Centre in Vayalanallur, Thiruvallur district and Urban Health and Training Centre, Thiruvanmyur in Chennai district, Tamil Nadu, India.

    Participants

    54 caregivers (27 rural, 27 urban, 46 mothers, 6 grandmothers, 2 fathers) of children younger than 5 years whose screen time exceeded WHO age-specific recommendations participated. Six FGDs were conducted, each with 8–10 participants.

    Methods

    FGDs were conducted in familiar community locations near the participants’ homes to ensure comfort and accessibility. The audio recordings were transcribed verbatim in Tamil and translated into English and analysed using inductive thematic analysis. Coding was manually performed by two independent researchers.

    Results

    Six major themes emerged: (1) circumstances leading to screen exposure, (2) perceived advantages, (3) perceived disadvantages, (4) challenges in reducing screen time, (5) methods adopted to reduce screen time and (6) strategies for sustaining reduction. Safety concerns, lack of play space and the need to manage household chores were commonly cited reasons for screen use. Although most caregivers were aware of the potential harms, screens were often used to feed or pacify children. Emotional resistance from children, inconsistent family norms and grandparents’ screen use were common barriers. Caregivers employed strategies, such as limiting access, engaging in outdoor play and enrolling children in structured activities. Urban–rural differences were minimal, and thematic saturation was achieved after six FGDs.

    Conclusions

    Caregivers face multiple, structural and family level challenges in managing screen time among young children. Awareness and interventions need to be tailored to address family dynamics, caregiver fatigue and lack of alternatives. Health providers, community workers and policymakers should collaborate to offer structured support, promote screen-free engagement and ensure child-friendly spaces in urban and rural communities.
