Utilisation of brain MRI for the diagnosis of dementia in low and middle-income countries: systematic review and meta-analysis

Por: Nassanga · R. · Nakasujja · N. · Mubuuke · A. G. · Lwere · K. · Kawooya · M. G. · Ocan · M. · Kaddumukasa · M.
Objectives

To synthesise the prevalence and patterns of dementia-relevant structural brain MRI abnormalities in adults with suspected or confirmed dementia in low- and middle-income countries (LMICs), and to summarise MRI protocols and the incremental diagnostic contribution of MRI beyond cognitive screening.

Design

Systematic review and meta-analysis.

Data sources

PubMed, EMBASE, Web of Science and PsycINFO (January 1990–27 January 2025), plus reference list screening and targeted manual searches.

Eligibility criteria

Observational or diagnostic-accuracy studies from World Bank-defined LMICs including adults (≥50 years) with suspected or confirmed dementia who underwent brain MRI as part of diagnostic evaluation.

Data extraction and synthesis

Two reviewers independently screened, extracted data and assessed risk of bias using ROBINS-I. Random-effects models pooled prevalence of dementia-relevant MRI abnormalities; diagnostic-accuracy outcomes were synthesised narratively due to heterogeneous reference standards and incomplete reporting.

Results

39 LMIC studies were included; 23 studies (2513 participants) contributed to the meta-analysis. Dementia-relevant MRI abnormalities (defined as ≥1 clinically relevant structural abnormality per study definition) were present in 1248/2513 participants. The pooled prevalence of dementia-relevant MRI abnormalities was 58% (95% CI 43% to 72%), with substantial heterogeneity (I²=95%) and a wide prediction interval (8–96%), indicating marked between-study variability; this estimate should be interpreted as a descriptive summary of study-level proportions rather than a precise population parameter.

Conclusions

Brain MRI frequently demonstrates dementia-relevant pathology in LMIC clinical cohorts, usually with mixed neurodegenerative-vascular patterns. Structured visual ratings may add aetiologic specificity beyond cognitive screening, but pooled estimates should be interpreted as summaries of heterogeneous study-level findings rather than precise population parameters, given high heterogeneity and risk of bias.

Patient and public involvement and engagement in target trial emulation framework: a scoping review protocol

Por: Egesa · I. J. · Baldwin · F. D. · Wells · M. · Maden · M. · Mbizvo · G. K. · Marson · A. G. · Tudur-Smith · C.
Introduction

Target trial emulation (TTE) has emerged as a methodological framework to strengthen causal inference from observational health data when randomised controlled trials are infeasible. The credibility of TTE studies depends not only on rigorous design and transparent reporting, but also on their relevance and acceptability to patients and the public. Patient and public involvement and engagement (PPIE) has been shown to enhance the relevance, transparency and impact of health research by shaping research priorities, informing study design and ensuring outcomes reflect patient perspectives. However, the extent to which PPIE has been incorporated into TTE studies remains unclear. This scoping review aims to systematically map the use and reporting of PPIE in published TTE studies.

Methods and analysis

This review will follow the Joanna Briggs Institute methodology for scoping reviews and will be reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis extension for Scoping Reviews checklist. We will search MEDLINE (Ovid) and Embase (Ovid) from January 2011 to present, limited to English-language publications. Eligible studies will be studies that self-identify as using the TTE framework and report empirical analyses of health outcomes using observational or trial data. We will exclude protocols, methodological or simulation-only studies, preprints, conference abstracts and grey literature. Three reviewers will independently screen titles and abstracts, and then full texts, with disagreements resolved by discussion or adjudication. Data extraction will include study characteristics and PPIE information guided by the Guidance for Reporting Involvement of Patients and the Public 2-Short Form checklist. Findings will be summarised using descriptive statistics, tables, figures and narrative synthesis.

Ethics and dissemination

Ethics approval is not required, as this review will use publicly available data. Results will be disseminated through a peer-reviewed publication and presented at conferences.

Deaths with preceding hospitalisations within 180 days in eight countries in sub-Saharan Africa and South Asia: A secondary descriptive analysis of the Child Health and Mortality Prevention Surveillance (CHAMPS) network

Por: Varo · R. · Cole · K. · Madewell · Z. J. · Iglesias · J. F. · Igunza · K. A. · Akelo · V. · Mugah · C. · Onyango · D. · Were · J. A. · Madhi · S. A. · Dangor · Z. · Johnstone · S. · Lala · S. G. · Ruder · T. · Mandomando · I. · Kincardett · M. · Xerinda · E. G. · Scott · J. A. G. · Assefa
Objectives

To describe (1) the proportion of deaths that were in recently hospitalised children and (2) causes of mortality among deceased children aged 0–59 months with preceding hospitalisations who enrolled in a mortality surveillance programme.

Design

Descriptive study using prospectively collected data.

Setting

Eight Child Health and Mortality Prevention Surveillance (CHAMPS) community and healthcare sites in sub-Saharan Africa and South Asia.

Participants

Deaths among children aged 0–59 months enrolled in CHAMPS 2016–2023.

Interventions

None.

Primary and secondary outcome measures

Deaths with antecedent hospitalisations within 180 days of death. Causes of death determined by expert panels who reviewed clinical data and histopathologic and microbiologic results from postmortem minimally invasive tissue sampling.

Results

CHAMPS enrolled 8548 deaths; we excluded 3688 neonates who died before discharge or ≤24 hours of birth and 482 with unclear information on antecedent hospitalisations. Out of the 4378 remaining deaths, 16.7% (95% CI 15.7% to 17.9%) were deaths that occurred within 180 days of a hospitalisation (n=733/4378). Of these, 55.7% (95% CI 52.0% to 59.3%) occurred outside healthcare facilities. Among included deaths with minimally invasive tissue sampling completed (n=337), lower respiratory tract infections (41.2%, 95% CI 36.0% to 46.7%), sepsis (39.8%, 95% CI 34.5% to 45.2%) and undernutrition (n=92, 27.3%, 95% CI 22.7% to 32.4%) were most common causes of death among cases with antecedent hospitalisations. The greatest proportion of deaths with antecedent hospital admissions occurred among cases aged 1–11 months (48.0%, 95% CI 44.4% to 51.7%), compared with those aged 0–1 months (21.7%, 95% CI 18.8% to 24.9%) and those aged 1–5 years (30.3%, 95% CI 27.0% to 33.8%). Moreover, the greatest proportion of deaths with antecedent hospital admissions occurred among infants/children with weight-for-age Z-score of

Conclusions

We observed a high proportion of deaths with antecedent hospitalisations within 180 days among young children across eight sites in sub-Saharan Africa and Asia. Among those deaths, children aged 1–11 months and undernourished infants were over-represented, suggesting early follow-up as a potential point to focus targeted support and future research.

Random-effects modelling of timely initiation of breastfeeding in Tanzania: What predicts the practice?

Por: Tibenderana · J. R. · Musa · K. M. · Pius · A. G. · Kagasyeko · J. N. · Kessy · S. A.
Objective

To determine individual and community-level predictors associated with timely initiation of breastfeeding among women in Tanzania.

Design

Analytical cross-sectional study.

Setting

This was an analytical cross-sectional study that used the 2022 Tanzania Demographic and Health Survey, which was conducted across all regions of Tanzania.

Participants

Data from 4308 women were included.

Primary outcome

The outcome variable was timely initiation of breastfeeding, defined as starting breastfeeding within the first hour after birth, coded as 1 if timely and 0 otherwise. Mixed-effects generalised linear model (family- Binomial and link-logit) approach was used to account for the hierarchical structure of the data. Four models were constructed to assess individual and community-level predictors. Adjusted prevalence ratios (APRs) with 95% CIs were reported.

Results

Women aged 25–34 years were significantly more likely to initiate breastfeeding within 1 hour (APR=1.40; 95% CI 1.18 to 1.65). Vaginal delivery was strongly associated with the timely initiation of breastfeeding (TIBF) (APR=10.13; 95% CI 7.84 to 13.09), whereas home delivery (APR=0.29; 95% CI 0.24 to 0.36) was negatively associated with TIBF. Multiparity (APR=1.22; 95% CI 1.04 to 1.43) increased the likelihood of TIBF. Women in the richest wealth category were less likely to practise TIBF (APR=0.70; 95% CI 0.51 to 0.96). Approximately 12.3% of the variation in TIBF was explained by cluster-level differences.

Conclusions

Both individual and community-level factors influence TIBF in Tanzania, highlighting the need for strong communication between mothers and healthcare providers to consistently promote its importance across all ages and wealth groups.

Barriers and facilitators to implementing a shared decision-making tool for anticoagulant-related drug-drug interactions: a qualitative study across three academic medical centres in the USA

Por: Becker · R. A. · Bonnet · K. · Shah · M. V. · Dang · E. · Ancker · J. S. · Malone · D. C. · Trinkley · K. E. · Gomez-Lumbreras · A. · Del Fiol · G. · Kawamoto · K. · Tawfik · A. G. · Cornia · R. · Jones · A. E. · Mitchell · J. · Reese · T. J.
Objectives

To identify barriers and facilitators to implementing an electronic shared decision-making tool for managing anticoagulant-related drug-drug interactions that affect bleeding risk in routine clinical care.

Design

Preimplementation qualitative study using semistructured interviews.

Setting

Three academic medical centres in the southeastern and western USA. Interviews were conducted between 27 March and 25 September 2024.

Participants

36 participants, including 19 clinicians involved in prescribing or managing anticoagulants and seventeen patients prescribed anticoagulants, were recruited using purposive and convenience sampling.

Results

Participants identified multiple barriers and facilitators to tool implementation. Common barriers included limited visit time, challenges integrating the tool into existing workflows, role and scope-of-practice constraints, and variation in patient digital literacy. Facilitators included clear visualisation of bleeding risk, access to supporting evidence, familiar interface design and perceived potential to support patient engagement and shared decision-making. Several determinants functioned as both barriers and facilitators, depending on clinical context and user role.

Conclusions

This preimplementation qualitative study identified context-specific determinants that influence the adoption of an electronic shared decision-making tool for anticoagulant-related drug–drug interactions. Findings highlight the importance of early attention to workflow integration, role alignment and usability to support uptake in routine care. Addressing these factors during design and implementation may inform strategies to support adoption and future evaluation in real-world clinical settings.

Can topical coconut oil reduce late-onset sepsis in extremely preterm infants? A pragmatic cluster-randomised controlled trial protocol

Por: Strunk · T. · Mountain · J. · Gordon · A. · Deshpande · G. · van den Boom · J. · DePaoli · A. G. · Jacobs · S. · Giannoutsos · N. · Doherty · D. A. · Patole · S.
Introduction

Infants born before 28 weeks’ gestation account for approximately 75% of neonatal morbidity and mortality. Late-onset sepsis (LOS) affects around 25% of these infants and is associated with an increased risk of adverse long-term outcomes. The topical application of coconut oil has been used for centuries in newborn care. Coconut oil is rich in saturated fatty acids, several of which have demonstrated antimicrobial properties. It is considered safe for extremely preterm infants, improves skin condition and may reduce the incidence of LOS.

Methods and analysis

This is a pragmatic, cluster-randomised, two-arm, parallel-group, multicentre, phase III clinical trial evaluating the effect of topical coconut oil versus routine skin care on the incidence of LOS in extremely preterm infants. Participating neonatal units will be cluster-randomised, and all infants born at

Ethics and dissemination

Following ethical approval, patients will be recruited at participating sites under a waiver of consent with opt-out framework. The trial results will be disseminated through conferences, media sources and publication in relevant peer-reviewed journals.

Incorporation of social medicine curriculum in academic and community health centres: a scoping review protocol

Por: Cydis · M. · Hudson · E. · Shipper · A. G. · Lane · A. · Salzman · M.
Introduction

In the field of medicine, there has been a growing understanding of the impact of social and economic inequities on patients’ health outcomes. Social medicine was established with the intention of addressing these social and economic drivers of health when caring for patients. Physicians who practise social medicine aim to take an interdisciplinary and interprofessional approach to patient care with an emphasis on the promotion of health equity and patient advocacy. As the effects of social determinants of health (SDOH) on health outcomes have become more widely appreciated, medical professional organisations and accrediting bodies have advocated for formal education on the impact of SDOH in undergraduate and graduate medical curricula. The goal of this scoping review is to examine how undergraduate and graduate medical education programmes in the USA have implemented social medicine concepts into their curricula.

Methods and analysis

The proposed scoping review will be conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews. The review team worked with a medical librarian, who created a unique search for five databases (PubMed, Embase, Cochrane CENTRAL Register of Controlled Trials, ERIC and the Web of Science Core Collection). Additionally, we will conduct a grey literature search that includes medical school and residency programme websites, as well as Association of American Medical Colleges (AAMC), Council of Residency Directors in Emergency Medicine (CORD), Alliance for Academic Internal Medicine (AAIM) and Society for Academic Emergency Medicine (SAEM) conference abstracts. Two independent reviewers will assess all articles for eligibility. Data will be extracted using the Covidence data extraction tool. We will present the results of the extraction in tabular form. Themes identified during the full-text review and data extraction process will be discussed.

Ethics and dissemination

Data will be gathered from publicly accessible sources, so ethics approval is not necessary. The results will be disseminated through a peer-reviewed journal and reported at conferences related to medical education and social medicine.

This protocol is registered on OSF (https://doi.org/10.17605/OSF.IO/7PZ8U).

Feasibility of a phase 3 partially randomised clinical trial to assess the safety and efficacy of paediatric praziquantel for schistosomiasis treatment in children aged 3 months to 6 years in endemic regions of Brazil: a pilot study

Objective

This study assessed the feasibility of implementing a phase 3 field-based clinical trial protocol to evaluate paediatric praziquantel (PED-PZQ) for the treatment of Schistosoma mansoni infection in children aged 3 months to 6 years in endemic areas of Brazil, focusing on operational aspects such as recruitment logistics, documentation management, investigational product handling and protocol adherence.

Design

Pilot and feasibility study for a phase 3 clinical trial, comprising two components: a randomised, open-label, parallel-group, two-arm trial and a single-arm trial.

Setting

Conde, Bahia, Brazil, from December 2024 to January 2025.

Participants

Two trials aim to screen 5774 participants from three rural areas in Bahia and three in Sergipe, states in northeastern Brazil, and enrol 403 children eligible for either randomisation or allocation. Trial 1 will randomise (1:1 ratio) 240 children aged 4–6 years into the PED-PZQ treatment arm or the standard praziquantel (PZQ) 1. Trial 2 will enrol 163 children aged 3 months to 3 years, all receiving PED-PZQ. Both trials are open label. Eligible participants shall meet age criteria, test positive for S. mansoni and fulfil other inclusion criteria. In the first recruiting centre, Conde (Bahia), it was estimated that 650 participants would need to be screened for trial 1 and 552 for trial 2, assuming schistosomiasis prevalence of 5% and 4%, respectively. This pilot study reports on the first 60 participants enrolled.

Primary and secondary outcome measures

The primary outcome of this pilot study is the feasibility of implementing the research protocol in a real-world field setting, focusing on key aspects such as study documentation challenges, participant safety, investigational medicinal product custody chain and protocol adherence. In addition to providing preliminary data on the parasitological cure rate, secondary outcomes include the prevalence of S. mansoni infection and the reduction in S. mansoni egg count (Kato-Katz method). Furthermore, the occurrence and severity of drug-related adverse events are monitored from drug administration to day 21 post-treatment, alongside changes in renal, hepatic and cardiac functions assessed through biochemical markers.

Results

A total of 60 participants were recruited, and 55 provided stool samples for screening. The pilot phase demonstrated the feasibility of implementing the clinical protocol under field conditions, with successful completion of all planned procedures and minimal protocol deviations. Operational challenges were identified mainly in documentation processes, participant recruitment and investigational product management and were addressed through preventive and corrective quality assurance actions. The experience also highlighted logistical and infrastructural barriers typical of field-based trials in remote endemic areas, which informed adjustments for the subsequent phase 3 study. Preliminary parasitological results indicated an overall S. mansoni prevalence of 9.1% (5/55), with 21% in trial 1 and 2.8% in trial 2. All infected participants met the eligibility criteria, received treatment and completed follow-up. Four achieved a parasitological cure, and one case of treatment failure was observed (trial 1, PZQ group). Two mild adverse events (diarrhoea) were reported, with no serious complications or clinically significant changes in biochemical parameters.

Conclusions

This pilot study demonstrated the feasibility of implementing a field-based phase 3 clinical trial protocol for PED-PZQ in endemic areas of Brazil. The findings confirm that the protocol can be successfully applied in primary care settings, despite operational challenges related to recruitment, logistics and documentation. The study also provided preliminary evidence supporting the safety and effectiveness of the paediatric formulation and highlighted the need to revise prevalence assumptions to improve future screening strategies. Overall, the experience offers valuable insights to guide the large-scale phase 3 trial and supports the incorporation of PED-PZQ into national schistosomiasis control policies.

Objectives

To test the agreement and usability of a novel quality appraisal tool: A MeaSurement Tool to Assess systematic Reviews of Prognostic Factor studies (AMSTAR-PF).

Design

Observational study.

Participants

14 appraisers of varied experience levels and backgrounds, including undergraduate, master’s and PhD students, postgraduate researchers, research fellows and clinicians.

Study procedure

Eight systematic reviews were rated by all reviewers using AMSTAR-PF.

Outcome measures

Planned measures included intrapair and inter-pair agreement using Cohen’s and Fleiss’ kappa, time of use and time to reach consensus. Interrater agreement was an added measure, and Gwet’s agreement coefficient was calculated and presented due to its greater stability across agreement levels. The percentage of intrapair agreements identical or one category apart was also presented.

Results

Interrater agreement averaged 0.59 (range 0.21–0.90), inter-pair agreement 0.61 (range 0.24–0.91) and intrapair agreement 0.75 (range 0.45–0.95) across the domains, with agreement for the overall rating 0.46 (95% CI 0.30 to 0.62) for interrater agreement, 0.46 (95% CI 0.17 to 0.74) for inter-pair agreement and 0.68 (range of averages 0.22–1.00) for intrapair agreement. The majority (60.7%) of intrapair ratings were identical, with 94.6% of final ratings either identical or only one category different for the overall appraisal. The time taken to appraise a study with AMSTAR-PF improved with use and averaged around 34 min after the first two appraisals.

Conclusions

Despite some variance in agreement for different domains and between different appraisers, the testing results suggest that AMSTAR-PF has clear utility for appraising the quality of systematic reviews of prognostic factor studies.

Rationale and design of the REMECHOQUE multicentre registry protocol: evaluating therapeutic trends in cardiogenic shock

Introduction

Cardiogenic shock (CS) is a complex syndrome characterised by primary cardiac dysfunction. Despite advances in therapeutic options such as mechanical cardiac support, it remains associated with high mortality. Although previous registries have described heterogeneous populations and outcomes across different centres, contemporary real-world data on management practices remain limited. This gap is particularly evident in low- and middle-income countries, where there is no robust registry that clearly defines the current state of CS management. Therefore, a multicentre registry is needed to better characterise current practices and outcomes. Our study aims to gain insight into current therapeutic trends in Mexico, a low- to middle-income country with a significant cardiovascular disease burden.

Methods and analysis

The Mexican Registry of Cardiogenic Shock is a quality initiative that aims to identify therapeutic trends, demographic characteristics and clinical presentations. It also aims to evaluate outcomes, including mortality and cognitive function at in-hospital and 1-year follow-ups, and to identify areas for improvement in the care process across the broad spectrum of CS.

Ethics and dissemination

Ethical approval for this multicentre study was obtained from the local research ethics committees of all participating institutions. The study results will be disseminated to all participating institutions in the form of summary reports and presentations on completion of the analysis.

Protocol for a cervical screening implementation trial comparing two approaches for delivering HPV self-collection in low-resource settings in India: a type 3 hybrid cluster randomised controlled trial (SHE-CAN)

Por: Oommen · A. M. · Ashfaq · M. · Tonsing · M. V. · Cherian · A. G. · Singarayar · P. · Viswanathan · V. · Muniswamy · V. · Hawkes · D. · Abraham · P. · Pricilla · R. A. · Manoharan · R. · Zomawia · E. · Oldenburg · B. · Saville · M. · Krishnaraj · K. · T S · S. · Basu · P. · Brotherton · J.
Background

Although multiple studies have offered self-collection for human papillomavirus (HPV)-based cervical screening in community settings, there are no randomised controlled trials (RCTs) that have compared implementation outcomes of programme approaches for self-collection. This trial will compare two such approaches in low-resource settings in the states of Tamil Nadu and Mizoram, India.

Methods

A cluster RCT will be conducted over a year, offering self-collection to 3000 women aged 30–49 from 28 clusters (average size 101) in selected districts. Clusters in tribal, rural and urban low-income settings will be randomised to two arms. The intervention arm, co-designed with multiple stakeholders, will involve campaigns to offer self-collection in the community. The comparison arm will be offered self-collection at the nearest health facilities.

HPV-based cervical screening will be performed at central laboratories using clinically validated screening assays that can identify the highest risk carcinogenic HPV types (Group 1a–c - HPV16/18/31/33/45/52/58, ±35). Ablative treatment will be based on positivity with this extended genotyping triage, while those with any of the lower carcinogenic HPV types (Group 1d - 39, 51, 56, 59, ±35, Groups 2a/b - 66, 68) will undergo further assessment with visual inspection with acetic acid. Outcomes will be evaluated quantitatively and qualitatively using RE-AIM and the Theoretical Framework of Acceptability.

Analysis

The primary outcome will be percentage of women well-managed (screened and appropriately treated) in both arms, with secondary outcomes including proportion screened, proportion treated, acceptability (willingness to screen, rescreen, and/or recommend to others) to women, community and healthcare providers, adoption (by providers), implementation fidelity, costs, sustainability assessment and systematically identified implementation barriers and facilitators. The reach, effectiveness and acceptability of community-based self-collection and the use of extended genotyping for triage in resource-constrained, hard-to-reach populations will be assessed, with lessons that can inform future statewide and national programmes.

Ethics and dissemination

Ethics approval has been obtained from the Institutional Review Board (IRB) and Ethics Committee of the Christian Medical College Vellore, Tamil Nadu, India (IRB Min.

Development and validation of a risk prediction model for chronic kidney disease among adult hypertensive patients having follow-up at University of Gondar Comprehensive Specialised Hospital, Ethiopia: a retrospective cohort study

Por: Tilahun · A. D. · Limenih · M. A. · Muluneh · A. G. · Hailu · W. · Anlay · D. Z. · Liyew · B. · Muche · A. A.
Objective

Chronic kidney disease (CKD) arises due to uncontrolled hypertension (HTN). HTN significantly increases the risk of complications in vital organs, mainly the kidneys. If hypertensive individuals receive early intervention, the majority of these complications and deaths from CKD can be avoided. Having a clinically applicable tool to predict the future risk of those complications can prevent early disability and premature mortality. However, to this day, there is a lack of a validated risk prediction model specifically designed for CKD of hypertensive patients in Ethiopia. We aimed to develop a risk prediction model for CKD among hypertensive patients at the University of Gondar Comprehensive Specialised Hospital (UoGCSH), Ethiopia.

Study design

A retrospective follow-up study was conducted from 1 January 2012 to 30 December 2021. The Least Absolute Shrinkage and Selection Operator regression methods were used to select predictors. The performance of the models was assessed using the Area Under the Curve and calibration plots. The internal validity of the model was evaluated using bootstrapping methods, and the model was presented as a nomogram. Decision curve analysis was conducted to assess the net benefit of the prediction model in clinical and public health contexts.

Setting

Data from patients’ medical records were collected via the Kobo Toolbox in the UoGCSH.

Participant

We followed a total of 1120 Patients diagnosed with HTN.

Results

The incidence of CKD among adult hypertensive patients was 19.82% (95% CI 17.59% to 22.26%). In the multivariable logistic regression analysis, age, residency, baseline blood pressure status, type of HTN, family history of HTN, baseline serum creatinine levels, proteinuria at baseline and dyslipidaemia were identified as statistically significant predictors of CKD. The nomogram demonstrated a discriminatory power of 91.98% (95% CI 90.09% to 93.88%) and a calibration p value of 0.327. The sensitivity and specificity of the prediction model were 80.63% (95% CI 74.81% to 85.61%) and 87.97% (95% CI 85.66% to 90.03%), respectively. The developed nomogram has a greater net benefit than using the treat-all or treat-none strategies when the threshold probability of the patient is increased.

Conclusion

The nomogram demonstrated excellent discrimination and calibration in identifying hypertensive patients at high risk of CKD. This predictive model offers clinicians a valuable tool for early identification of high-risk individuals, enabling timely interventions, personalised counselling and optimised management through close monitoring to prevent disease progression.

Objective

To assess how preoperative anaemia affects surgical outcomes in elderly patients within a resource-limited setting.

Design

Prospective cohort study.

Setting

Two comprehensive specialised hospitals in Ethiopia.

Participants

Participants consisted of 224 patients aged 65 years and older who underwent surgery between 1 December 2024 and 29 March 2025.

Primary and secondary outcome measures

Perioperative blood transfusions were the primary outcome. Secondary outcomes included intensive care unit (ICU) admission, risk of postoperative complications, prolonged hospitalisation, poor recovery quality and in-hospital mortality.

Results

The anaemic group required transfusions of three or more units more frequently than the non-anaemic group (10.5% vs 2.6%; absolute risk difference 8.0%). Their perioperative transfusion rates were significantly higher (42.3% vs 18.4%; p

Conclusion and recommendation

Preoperative anaemia significantly increases the risk of transfusion, poor recovery, ICU admission, prolonged hospitalisation and in-hospital mortality in older patients who underwent surgery. In resource-limited settings, improving perioperative outcomes should prioritise the early detection and treatment of anaemia.

Objective

The study aimed to assess the prevalence of financial catastrophe and explore patients’ perceived effectiveness of the government support programme related to chronic kidney disease.

Design

Cross-sectional mixed-method study.

Participants

A total of 120 patients receiving free regular haemodialysis under the government’s Deprived Citizen Support Programme for at least 6 months were included in the quantitative study, and 9 patients participated in the qualitative study.

Main outcome measures

Prevalence of financial catastrophe and factors associated with financial catastrophe among chronic kidney disease patients undergoing haemodialysis.

Methods

A convergent parallel mixed-method approach was carried out from 15 June to 15 December 2024, among chronic kidney disease patients undergoing haemodialysis at the National Kidney Center. Quantitative data were collected through face-to-face interviews using a semi-structured questionnaire. Financial catastrophe was defined as out-of-pocket (OOP) healthcare payments ≥40% of a household’s disposable income, following the WHO-recommended threshold for severe financial burden. OOP expenditures were assessed over 6 months, and associations were tested using 2 and binary logistic regression at a 95% CI in SPSS V.25.0. For the qualitative arm, in-depth interviews were conducted with nine purposively selected patients, and inductive thematic analysis was applied to explore the perceived effectiveness of the government support programme. The quantitative and qualitative findings were then integrated to achieve convergence and divergence, allowing for a comprehensive understanding of the extent and context of financial hardship among patients.

Results

The prevalence of financial catastrophe was 72.5%. The factors associated with financial catastrophe were the presence of complications (adjusted OR (AOR): 3.67, 95% CI 1.019 to 13.27), patients without financial support (AOR: 2.77, 95% CI 1.016 to 7.56) and reduction in food expenses (AOR: 0.313, 95% CI 0.109 to 0.896). Qualitative findings on awareness regarding government subsidies, financial strain, barriers to receiving treatment and perceived effectiveness of the programme revealed key aspects of utilisation and effectiveness of the government support programme.

Conclusion

The prevalence of financial catastrophe was substantially high, which highlights the importance of addressing economic challenges in chronic kidney disease care. The study emphasised the need to strengthen financial protection through the expansion of government subsidies and improved insurance coverage.

Objectives

To identify enablers and barriers for scaling up non-communicable disease (NCD) interventions across diverse global contexts and to map these factors to the WHO’s health system building blocks.

Design

A multi-method qualitative study applying the Consolidated Framework for Implementation Research to analyse data from multiple projects nearing or completing scale-up.

Setting

Global Alliance for Chronic Diseases-funded implementation research projects conducted across 18 low- and middle-income countries and high-income settings.

Participants

Data was derived from documents (n=77) including peer-reviewed publications, policy briefs, and reports and interviews with stakeholders (n=18) (eg, principal investigators, medical professionals, public health workers).

Interventions

Various context-specific interventions targeting sustainable scale-up of NCD (eg, diabetes, hypertension, cardiovascular disease) interventions at the community, primary care or policy levels.

Primary and secondary outcome measures

The primary outcome was identifying contextual enablers and barriers to intervention scale-up. Secondary outcomes included exploring how these factors aligned with health system building blocks (eg, leadership/governance, healthcare workforce).

Results

Twenty enablers (eg, intervention adaptability, strong stakeholder engagement, local empowerment) and 25 barriers (eg, resource limitations, intervention complexity, stakeholder burnout) were identified. Contextual alignment, supportive governance and capacity building were critical for sustainability, while cultural misalignment and socio-political instability frequently hampered scaling efforts.

Conclusions

Tailoring interventions to local health systems, ensuring stakeholder co-ownership and incorporating strategies to mitigate stakeholder burn-out are essential to achieving sustainable, scalable NCD solutions. Future research should focus on integrating systematic cultural adaptation, sustainable financing and workforce capacity building into scale-up planning.

Risk prediction in people with acute myocardial infarction in England: a cohort study using data from 1521 general practices

Objective

To develop prediction models for short-term outcomes following a first acute myocardial infarction (AMI) event (index) or for past AMI events (prevalent) in a national primary care cohort.

Design

Retrospective cohort study using logistic regression models to estimate 1-year and 5-year risks of all-cause mortality and composite cardiovascular outcomes.

Setting

Primary care practices in England contributing data to the Clinical Practice Research Datalink (CPRD) Aurum and CPRD GOLD databases between 2006 and 2019.

Participants

Patients with an incident (index) or prevalent AMI event. Models were trained on a random 80% sample of CPRD Aurum (n=1018 practices), internally validated on the remaining 20% (n=255) and externally validated using CPRD GOLD (n=248).

Outcome measures

Discrimination assessed using sensitivity, specificity and area under the receiver operating characteristic curve (AUC). Calibration assessed using calibration plots.

Results

In the index (prevalent) cohorts, 94 241 (64 789) patients were included in the training and internal validation sets, and 16 832 (7479) in the external validation set. For the index cohort, AUCs for 1-year [5-year] all-cause mortality were 0.802 (95% CI 0.793 to 0.812) [0.847 (0.841 to 0.853)] internally and 0.800 (0.790 to 0.810) [0.841 (0.835 to 0.847)] externally. For the primary composite outcome (stroke, heart failure and all-cause death), AUCs were 0.763 (0.756 to 0.771) [0.824 (0.818 to 0.830)] internally and 0.748 (0.739 to 0.756) [0.808 (0.801 to 0.815)] externally. Discrimination was higher in the prevalent cohort, particularly for 1-year mortality (AUC: 0.896, 95% CI 0.887 to 0.904). Models excluding treatment variables showed slightly lower but comparable performance. Calibration was acceptable across models.

Conclusions

These models can support clinicians in identifying patients at increased risk of short-term adverse outcomes following AMI, whether newly diagnosed or with a prior history. This can inform monitoring strategies and secondary prevention and guide patient counselling on modifiable risk factors.

Leadership in the health professions in the Philippines: a scoping review protocol

Por: Gabrieles · M. · Lipana · A. G. R. · Dicolen · E.
Introduction

Research indicates that leadership in the health professions can facilitate improvement of quality and efficiency of healthcare services. In the Philippines, leadership in the health professions plays a critical role in driving improvements in healthcare delivery and health professions education. Thus, the landscape of leadership in the health professions merits continuous exploration and deeper understanding. This scoping review aims to explore the landscape of leadership in the health professions in the Philippines. The scoping review will include published and unpublished research papers of any kind, such as primary research studies, systematic reviews, meta-analyses, letters, guidelines, websites, blogs and grey literature that report about leadership in the health professions in the Philippines. Exclusions are leadership studies on the health professions that discuss the professions outside the scope and context of the practice.

Methods and analysis

The Joanna Briggs Institute (JBI) methodological framework for scoping review will be used in this review. A three-step search strategy will be used consisting of an initial search, full search and screening of reference lists. The databases that will be included are Cinahl Ultimate, Cochrane Library, Scopus, Embase, Emcare, Web of Science, JBI Evidence-based Practice Database, PubMed/Medline, ERIC, local journals and grey literature to determine pertinent sources about the topic. Sources searched will be screened by two independent reviewers and data will be extracted using a data extraction table. Disagreements will be resolved by a discussion through a third reviewer. The results of the search and the study inclusion process will be reported in full in the final scoping review and presented in a Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping review flow diagram. Search strategy using the included databases started in August to September 2025, data extraction will start by October 2025, data analysis will start by November 2025 and the review is expected to be completed by December 2025.

Ethics and dissemination

This study does not involve human participants and has been reviewed and classified for exempted review by the University of the Philippines Manila Research Ethics Board, which is a committee whose task is to make sure that research participants are protected from harm. The findings of the scoping review will be disseminated through conference presentations and publication in a scientific journal.

Introduction

Tobacco use is the most significant modifiable risk factor for adverse health outcomes, and early research indicates there are also significant harms associated with vaping. National targets aim to reduce smoking and vaping during pregnancy for Aboriginal and Torres Strait Islander people. While most Aboriginal and Torres Strait Islander people want to quit, cessation is frequently attempted without support, increasing the chance of relapse. Group-based smoking cessation programmes increase quit success by 50%–130% in the general population; however, they have never been evaluated in Aboriginal and/or Torres Strait Islander communities.

Methods and analysis

The Gulibaa study is an Indigenous-led and community-embedded project that will co-design, implement and evaluate a group-based model of care to support Aboriginal and Torres Strait Islander women to be smoke- and vape-free. Staff of Health Services in New South Wales, Australia, will receive training to deliver a face-to-face group-based smoking and vaping cessation intervention. Aboriginal and/or Torres Strait Islander people who identify as a woman or non-binary, are pregnant or of reproductive age (16 to 49 years), currently smoke or vape at least once per day and are willing to attend the programme are eligible to participate. Up to 500 participants will be recruited. A mixed method evaluation approach will be implemented guided by the RE-AIM framework. Outcomes will include intervention reach, intervention effectiveness (determined primarily by self-reported 7-day point prevalence abstinence at 6 months follow-up), acceptability and feasibility of the intervention, programme fidelity and maintenance and cost effectiveness.

Ethics and dissemination

Embedding culturally safe support to quit during pregnancy can result in improved outcomes for both mother and child and immediately improve intergenerational health and well-being. Ethics approval has been provided by the Aboriginal Health and Medical Research Council and the University of Newcastle. Study findings will be disseminated to Aboriginal and Torres Strait Islander communities in ways that are meaningful to them, as well as through Aboriginal health services, key national bodies, relevant state and federal government departments.

Introduction

Patients who survive admission to intensive care unit (ICU) for critical illness are at high risk of developing muscle atrophy and weakness, commonly diagnosed as ICU-acquired weakness (ICUAW). The development of ICUAW is closely linked to long-term symptoms and impairments known as post-intensive care syndrome (PICS). Despite heightened recognition of impairments, there is limited research supporting effective interventions to improve muscle and physical outcomes after hospital discharge. Prior to developing and testing interventions for ICU survivors, it is imperative to understand the trajectory of muscle and physical function recovery following an ICU stay. The purpose of this study is to longitudinally investigate skeletal muscle health and physical function outcomes after ICU admission.

Methods and analysis

This protocol describes a single site, prospective, observational study in adult patients who have survived a critical illness (ie, sepsis or acute respiratory failure). Patients will participate in a battery of testing including primary outcomes: muscle power and physical function; and secondary outcomes: muscle strength, muscle size, endurance and physical activity (by accelerometry) at hospital discharge and 3, 6, and 12 months post-discharge. A subset of patients will participate in muscle biopsy and venipuncture. To examine if the trajectory of recovery predicts primary outcomes, we will perform multivariate linear regression models in 150 evaluable patients. To examine differences in molecular and cellular outcomes in plasma and muscle tissue, a control group of community-dwelling adults without history of an ICU stay will be enrolled as a comparator group. Enrolment started on 18 October 2022 with an estimated completion date of 1 August 2027.

Ethics and dissemination

This protocol was approved by the University of Kentucky Office of Research Integrity Medical Internal Review Board (# 77407), with patients providing informed written consent. We anticipate our findings to establish recovery trajectories, improving the classification of patients who experience sustained physical disability. Improved identification of recovery trajectories of muscle and physical function enables future studies to employ an individually targeted rehabilitation approach, that is, precision medicine, with the goal of improving patient outcomes. The cellular findings will support the development of novel interventions specifically designed for detecting underlying mechanisms. We intend to disseminate findings to patients, healthcare professionals, the public and other relevant groups via conference presentations and manuscripts without publication restrictions.

Introduction

The utility of brain MRI in dementia diagnosis offers critical insights into structural brain changes, such as hippocampal and thalamic atrophy, which are hallmark features of Alzheimer’s disease and Alzheimer’s disease-related dementias . However, its use, especially in low- and middle-income countries (LMICs), is affected by limited accessibility. This protocol outlines a systematic review and meta-analysis to assess the diagnostic utility, feasibility and challenges of integrating brain MRI for dementia diagnosis in LMICs.

Methods and analysis

The review follows Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols with a priori eligibility criteria and is registered in PROSPERO. Searches (from inception to September 2025) will be run in MEDLINE/PubMed, EMBASE, Web of Science and PsycINFO, with supplementary bibliography screening. Adults ≥50 years in LMIC settings undergoing brain MRI for dementia evaluation will be eligible. Data will be synthesised narratively and, where appropriate, via random-effects meta-analysis with planned subgroup analyses by MRI approach (qualitative vs quantitative), magnet strength, sequence availability and reference standard. Screening and data extraction are planned for 1 November to 30 December 2025.
