Iron-folic acid (IFA) supplementation in pregnancy is recommended by the WHO, with a dose of 60 mg of iron in contexts where anaemia remains a severe public health problem. Iron-containing supplements may cause side effects that affect acceptability and adherence in a dose-response manner. Maternal multiple micronutrient supplements (MMS), which include iron and folic acid plus additional micronutrients, are also recommended in the context of rigorous research, and programmes are considering transitioning from IFA to MMS containing 30 mg of iron. We will evaluate the effect of iron dose in MMS on maternal acceptability, side effects, adherence and preferences.

The Multiple Micronutrient Supplementation (MMS) Iron Dose Acceptability Crossover Trial is an individually randomised, quadruple-blind, non-inferiority crossover trial of daily antenatal MMS supplementation formulations that contain 60 mg, 45 mg and 30 mg elemental iron among pregnant women in Dar es Salaam, Tanzania. A total of 156 pregnant participants will be randomised to a sequence in which they receive each of the three MMS formulations for 1 month. Participants, investigators, outcome assessors and data analysts will be blinded to the treatment sequence. The primary trial outcome is participant-reported acceptability of each MMS formulation, measured on a Likert scale. Secondary and tertiary outcomes include preferred and least preferred formulation, identification of MMS formulation, reported side effects and adherence assessed by pill count. Regression analyses will be used to assess differences between formulations and will account for sequence and period effects of the crossover trial design. Qualitative in-depth interviews from a subsample of participants will be conducted to understand women’s perceptions and experiences taking the different MMS formulations.

The trial protocol was approved by Harvard T. H. Chan School of Public Health Institutional Review Board (IRB), the Ifakara Health Institute IRB, the Muhimbili University of Health and Allied Sciences IRB, the National Health Research Ethics Sub-Committee and the Tanzania Medicine and Medical Device Authority. Results will be shared through publications and presentations at the local, regional and international levels.

This study was designed to determine the level of knowledge about the health impact of indoor air pollution (IAP) and associated factors among mothers in northeastern Ethiopia.

A community-based cross-sectional study was carried out from May to June 2024. A systematic sampling technique was used to select the study participants. Using a pretested and structured questionnaire, data were gathered through interviews. The collected data were entered into EpiData V.4.6 and SPSS V.25 was used for the analysis. The adjusted OR with a 95% CI and the significance of associations at p0.05 were determined.

The study was conducted in northeastern Ethiopia.

A total of 401 mothers participated in this study.

The primary outcome is the prevalence of good knowledge about the health impact of IAP.

With a response rate of 95%, 401 mothers in all completed the survey. Of the participants, 205 (51.1%) were aged ≤31 years. In this study, 46.4% (95% CI 41.6 to 51.4) of the 401 participants had good knowledge about the health impact of IAP. Higher educational level (adjusted OR (AOR): 4.4, 95% CI 2.38 to 8.14), higher income (AOR: 1.88, 95% CI 1.15 to 3.06) and receiving training (AOR: 2.72, 95% CI 1.14 to 6.46) were factors associated with having good knowledge.

This study concluded that less than half of the mothers had good knowledge about the health impact of IAP. The findings of this study highlight the critical need for policymakers to address the inadequate understanding among mothers of the health impact of IAP. Thus, the health education programme on IAP should be strengthened through effective community engagement.

Tuberculosis (TB) stigma is a critical barrier to timely diagnosis and treatment, yet few studies have quantified community-level TB stigma or its variability across geographic contexts. This study describes methods for capturing community-level TB stigma and examines stigma variability and correlations with community-level sociodemographic and TB-related factors across urban, periurban and rural communities.

Ecological study.

93 demarcated study communities in Buffalo City Metropolitan Health District, Eastern Cape, South Africa.

3869 heads of household, age ≥18 years, were surveyed in a geographically clustered random sample of households across the 93 study communities.

Validated scales were used to measure perceived TB stigma. Community levels of TB stigma were generated by aggregating individual responses within each study community.

Median community TB stigma scores varied significantly by community location: compared with urban communities, rural communities had lower TB stigma scores (beta=–0.235; 95% CI –0.362 to –0.108) while periurban communities had higher scores (beta=0.136; 95% CI 0.017 to 0.254). Community TB stigma was positively associated with community HIV stigma, with the strongest associations in urban (beta=0.977 (95% CI 0.634 to 1.321) and rural (beta=0.816 (95% CI 0.186 to 1.446) communities. No associations were observed between TB stigma and TB prevalence, TB knowledge or household demographics after adjusting for community location.

TB stigma varied meaningfully across communities and was associated with urbanicity and HIV stigma. Stigma is a complex social process and there may be many other factors shaping TB stigma at the community level. Future research and stigma-reduction interventions should consider local contexts and community-level determinants beyond individual demographics, TB knowledge or community TB burden.

School feeding programmes reach over 466 million children globally, making them one of the largest social safety nets worldwide. Beyond providing immediate nutritional benefits, school feeding programmes increasingly aim to strengthen local food systems through procurement from smallholder farmers, support for sustainable agriculture, community kitchen involvement and broader development outcomes. However, evidence on how school feeding programmes can simultaneously improve nutrition and educational outcomes while transforming food systems in low and middle-income countries (LMICs) remains fragmented. This systematic review will synthesise evidence on the effects of school feeding interventions with explicit food system components on health, nutrition, education and food system outcomes among school-age children and adolescents in LMICs.

We conducted comprehensive searches in MEDLINE (PubMed), Embase (Ovid), CENTRAL (Cochrane Library), Web of Science, Google Scholar, completed on 18 February 2026, with grey literature searches ongoing and to be completed subsequently. We will include randomised controlled trials (RCTs), non-RCTs and quasi-experimental studies with comparison groups examining school feeding interventions with food system components among school-age children and adolescents (5–19 years) in LMICs. Two reviewers will independently screen titles and abstracts, review full texts, extract data and assess study quality using the Cochrane Risk of Bias tools (RoB 2 for RCTs and Risk Of Bias In Non-Randomized Studies - of Interventions (ROBINS-I) for non-randomised studies). Certainty of evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. We will conduct narrative synthesis using the Synthesis Without Meta-analysis (SWiM) guidelines and meta-analysis where appropriate.

Ethical approval is not required for this systematic review as no primary data will be collected. Findings will be disseminated through peer-reviewed publication, conference presentations and policy briefs targeting international organisations, governments and development partners working on school feeding and food systems in LMICs.

To examine how household members, community health research workers (CHRWs) and broader social networks influenced pregnant women’s capabilities, opportunities and motivations to consume a daily balanced-energy protein (BEP) supplement or a multiple micronutrient supplement (MMS) in the context of an effectiveness trial in rural Bangladesh.

In-depth interviews, group interviews, focus group discussions, thematic analysis using the Capability, Opportunity, Motivation-Behaviour (COM-B) framework.

Gaibandha, Bangladesh.

Women (n=32) who had completed participation in the TARGET-BEP randomised trial, their husbands (n=13) and mothers-in-law (n=13), who participated in 13 group interviews, and CHRWs (n=39) who participated in six focus group discussions.

Capability to adhere to BEP and MMS was strengthened when family members understood the value of supplements and actively supported supplementation. Children emerged as unexpected facilitators, reminding mothers to consume supplements and tracking intake. Opportunity to use supplements consistently was enhanced by women’s educational attainment and the availability of household resources. Finally, motivation to take the supplements was influenced by many actors including neighbours, who could offer support but also often transmitted rumours and taboos, and CHRWs, who adeptly adapted adherence messages to the local context and to women’s specific concerns.

To improve antenatal supplement adherence and maternal–infant health in Bangladesh and similar contexts, pregnancy nutrition programmes should move beyond the woman-as-sole-agent paradigm by: (1) co-designing messages for husbands, mothers-in-law, children and neighbours in conversation with effective community health workers, such as those working in the TARGET-BEP trial; (2) equipping community health workers with flexible, family-engaging counselling strategies; and (3) complementing women’s education gains with gender-transformative and family-inclusive interventions.

(1) To compare the ability of body mass index (BMI), waist-to-height ratio and visceral fat, as measured by bioelectrical impedance analysis (BIA), to predict hypertension and diabetes in men and women and (2) to determine whether the correlation between BMI and visceral fat varies by height quantile.

We conducted a cross-sectional analysis of a representative survey that included data on anthropometrics, body composition, glycosylated haemoglobin and blood pressure. We used receiver operating characteristic analysis and DeLong CIs to compare the ability of each adiposity measure to predict diabetes and hypertension in each gender.

Tecpán and San Antonio Suchitepéquez, Guatemala.

806 non-pregnant adults from 347 households, primarily of Indigenous ethnicity.

Diabetes, defined as a haemoglobin A1c of greater than 6.5% or self-reported history and hypertension, defined as a systolic blood pressure over 140 or a diastolic blood pressure over 90.

Among the three adiposity measures, visceral fat was the best predictor of diabetes (area under the curve; AUC 0.73 (95% CI 0.66 to 0.81) (men); AUC 0.75 (95% CI 0.7 to 0.8) (women)) and hypertension (AUC 0.7 (95% CI 0.61 to 0.79) (men); AUC 0.76 (95% CI 0.7 to 0.82) (women)), followed by waist-to-height ratio followed by BMI. All three measures better predicted hypertension in women than in men. In sensitivity analysis, visceral fat and waist-to-height ratio better predicted hypertension and diabetes when BMI was below 30 kg/m². The correlation between BMI and visceral fat did not vary appreciably by height.

Of the three adiposity measures studied, BIA-derived visceral fat best predicted cardiometabolic disease in the population. In clinical practice, alternative techniques beyond BMI need to be considered when assessing adiposity, screening for cardiometabolic disease and diagnosing clinical obesity.

Large-for-gestational-age (LGA) and macrosomic births pose significant maternal and neonatal health risks, particularly in low- and middle-income countries (LMICs), where access to care are often limited. Despite well-established associations between LGA, macrosomia, and various risk factors, the relative contributions of these factors remain underexplored in LMICs. This study aims to identify risks factors for LGA and macrosomia in LMICs, with an emphasis on modifiable ones, and quantify their population attributable fractions (PAFs).

A systematic review will be conducted across the following databases: MEDLINE, Scopus and ProQuest Central and regional databases (Africa Index Medicus, Index Medicus for South Asia and Latin America and Caribbean literature of health sciences). Eligible studies will include observational studies, reviews and interventional research conducted between 2000 and 2025 that report on prevalence or association of risk factors for large-for-gestational-age (LGA) and/or macrosomia births in low- and middle-income countries (LMICs). Data extraction will encompass study characteristics, prevalence/incidence estimates, risk factor distributions and measures of association. Quality assessment will be performed by two independent reviewers using the Newcastle-Ottawa Scale for observational cohort, case–control and cross-sectional studies. While Cochrane Risk of Bias Tool will be used for randomised controlled trials and a Measurement Tool to Assess Quality of Systematic Reviews 2 (AMSTAR-2) for systematic reviews and meta-analyses. Meta-analyses using a random-effects model, which accounts for population heterogeneity, will synthesise risk estimates for factors examined in three or more studies from LMICs, up-to-date meta-analysis including all relevant studies identified through our search. Population attributable fractions for individual and combined risk factors will be calculated.

This systematic review will use only previously published information. Ethical approval is therefore not required. The results will be submitted for publication in a peer-reviewed journal and the findings will be presented at international conferences to engage relevant stakeholders including policymakers and public health organisations in LMICs with the aim of informing the development of targeted interventions to reduce the burden of LGA and macrosomia births in the region.

Healthcare contributes considerably to greenhouse gas emissions, particularly from operating theatres. The global demand for total hip replacements (THR) is rising, highlighting the need to understand its impact on the environment. The study aims to assess the environmental impact of THRs using life cycle assessment (LCA) and to identify key contributors.

A process-based LCA focusing on the surgical procedure was conducted in accordance with global standards (ISO 14040:2006 and ISO 14044:2006). Eleven sensitivity scenarios were performed to assess the robustness of the results.

A Danish University Hospital.

The empirical data involved the quantity and type of surgical equipment, material composition, energy usage and clinical infrastructure. There were no study participants.

No study interventions were performed.

18 environmental impact scores, such as global warming, human toxicity and water consumption, were assessed.

The carbon footprint of a THR was 62.0 kg CO₂e, with major contributors being single-use disposable utensils (54 %), implants (22 %), and sterilisation of non-disposable utensils (18 %). Operating theatre energy usage, non-disposable utensils and clinical infrastructure contributed less, at 3 %, 2 % and 1 % each. Although the results of the other 17 environmental impact scores varied, they were predominantly influenced by the same factors as the carbon footprint. The sensitivity analysis showed that the overall carbon footprint varied by no more than 6 % unless the energy system shifted to less renewable energy, potentially increasing the footprint by 47 %.

THRs impose a substantial environmental burden, and sustainable solutions should focus on the primary drivers of this impact: disposable utensils, implants and the sterilisation process. In contrast, clinical infrastructure and non-disposable utensils appear to have a relatively minimal environmental impact.

Intersectionality, as applied to health, provides a framework for understanding how overlapping social identities, such as ethnicity, gender and socioeconomic status, shape differential health outcomes and healthcare experiences. Individuals who occupy multiple marginalised identities often experience compounded disadvantages. Ethnic minority (EM) populations, defined here as social groups who are numerically smaller and/or socially marginalised within a given national or regional context based on ethnicity, race, culture, language, ancestry, or related heritage (often overlapping with racialised identities), frequently experience systemic exclusion, racism and structural barriers that also contribute to persistent disparities in morbidity, mortality and healthcare access. However, much health research relies on single-axis analyses, which can obscure within-group variation and may inadvertently reinforce inequities. Despite growing recognition of intersectionality, its empirical application to EM health remains limited. This systematic review aims to synthesise evidence on how intersectionality theory has been conceptualised and applied to understand health outcomes and healthcare utilisation among EM populations globally.

This systematic review will follow Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the PRISMA-Equity Extension. Comprehensive searches of peer-reviewed databases and grey literature, including MEDLINE, EMBASE, CINAHL Plus, Scopus, Web of Science and ProQuest will identify quantitative, qualitative and mixed-method empirical studies published from 2000 to 2026. Eligible studies must implement intersectionality theory to EM health or healthcare utilisation outcomes. Two independent reviewers will screen titles, abstracts and full-text articles. Data extraction will also be conducted independently and discrepancies will be discussed with input from a third reviewer. Guided by the PROGRESS-Plus equity framework, findings will be synthesised thematically, implementing a mixed-method convergent integrated synthesis design.

This review only analyses previously published data, thus it does not require ethical approval. Findings will be presented at relevant academic or professional conferences and submitted for publication in a peer-reviewed journal.

Digital health interventions have emerged as promising solutions to strengthen maternal, newborn and child health (MNCH) systems in low-income and middle-income countries (LMICs). Although evidence on their effectiveness is growing, corresponding economic evaluations remain limited, heterogeneous and fragmented. Understanding the value for money of digital health interventions is essential for supporting scale-up decisions and efficient resource allocation. This protocol outlines the methods for a systematic review synthesising economic evaluations of digital health interventions across the MNCH continuum in LMICs.

We will systematically search PubMed, Embase, Scopus, the Cochrane Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and Turning Research Into Practice (TRIP) Pro for peer-reviewed studies published from 1 January 2000 to 31 December 2025. Backward citation searching (reference lists of included articles) and forward citation tracking will be performed to ensure comprehensive study identification, and study authors will be contacted when necessary to obtain missing or unclear data. Artificial intelligence (AI)-based Deep Research tools will be used as a supplementary approach to identify additional keywords and assess the completeness of the search strategy. Eligible studies will include full and partial economic evaluations embedded within randomised controlled trials, quasi-experiments, controlled before–and–after studies, time-series analyses, cohort or case–control designs, implementation studies and economic modelling studies. Three reviewers will independently conduct study selection and data extraction using a predefined form adapted from the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) 2022 guidelines. Methodological quality will be assessed using the Drummond checklist. Due to heterogeneity in study designs and economic methods, a narrative synthesis will be conducted. Costs will be standardised to the US dollar (USD) in 2024.

This review will synthesise evidence from already published studies and does not involve the collection of primary data; therefore, ethical approval is not required. All data extracted will be derived from publicly available peer-reviewed literature, and no identifiable personal information will be used. The findings of this systematic review will be disseminated through publication in a peer-reviewed journal and presentations at academic conferences focused on global health, digital health and MNCH. In addition, the results will be shared with relevant stakeholders, including policymakers, programme implementers and organisations involved in digital health and MNCH in LMICs.

Environmental enteropathy (EE) is a syndrome affecting the gut characterised by villus blunting, reduced nutrient absorption and microbial translocation in children and adults experiencing a high burden of enteric infection due to inadequate access to clean water and sanitation.

We will conduct coordinated randomised controlled trials in six countries to determine if supplementation with indispensable amino acids (IAAs) can improve intestinal barrier dysfunction in six geographically diverse populations of 18–36 months old children with stunting or severe stunting. All trials will measure the same primary outcomes while secondary outcomes will be measured on a per-trial basis using standardised protocols across the project. The primary endpoint will be change in gut permeability as assessed by the lactulose/rhamnose ratio. Secondary endpoints include changes in amino acid and carbohydrate absorption using novel, isotope tracer tests. Other prespecified outcome measures include changes in EE biomarkers and child weight. IAA supplementation will be given daily for 28 days and evaluation of the major endpoints will be at baseline and after 28 days of supplementation.

Ethical approval will be obtained from the Research Ethics Committee at each participating site. Caregivers will provide written informed consent for each participant. Findings will be disseminated through peer-reviewed journals, conference presentations and face-to-face meetings with participant caregivers.

To evaluate the effects of nurse-led shared decision-making (SDM) on lung cancer screening outcomes, including low-dose CT (LDCT) uptake, benign findings, early cancer detection and willingness to participate among high-risk populations.

Systematic review and meta-analysis.

PubMed, Medline via OvidSP, Cochrane Central Register of Controlled Trials, EMBASE via OvidSP, Web of Science, Scopus, grey literature databases and clinical trial registries were searched from inception to March 2025.

Studies evaluating nurse-led SDM interventions in high-risk lung cancer populations, reporting outcomes including LDCT uptake rates, screening results (Lung-RADS (Lung Imaging Reporting and Data System) classifications), early-stage cancer detection or willingness to participate. Randomised controlled trials, quasi-experimental studies and observational studies were included.

Two reviewers independently extracted data and assessed risk of bias using the Risk of Bias in Non-randomised Studies of Interventions (for non-randomised studies) and Cochrane Risk of Bias 2.0 (for randomised controlled trials). Meta-analyses were conducted using random-effects models. Meta-regression explored sources of heterogeneity.

13 studies (n=13 608 participants) were included, comprising 10 single-arm studies and three comparative studies. In single-arm studies without control groups, nurse-led SDM programmes achieved a pooled LDCT uptake rate of 98% (95% CI 28% to 100%; I²=99%), and willingness to participate was 68% (95% CI 24% to 93%; I²=98%). In comparative studies, nurse-led SDM showed no significant difference in LDCT uptake compared with usual care (RR 1.00, 95% CI 0.99 to 1.02; I²=0%), suggesting non-inferiority rather than superiority. Among individuals who completed screening, 81% (95% CI 77% to 85%) had benign or low-risk findings (Lung-RADS [Lung Imaging Reporting and Data System] I/II), and 2% (95% CI 1% to 3%) were diagnosed with early-stage lung cancer, rates consistent with benchmark screening trials. Meta-regression identified female sex as positively associated with uptake (β=0.54, p

Comparative evidence suggests that nurse-led SDM achieves equivalent LDCT uptake to standard care approaches, indicating feasibility as an alternative service delivery model. However, the predominance of single-arm studies, high heterogeneity and moderate-to-serious risk of bias limit causal inference. High uptake rates in single-arm studies likely reflect selection bias rather than intervention effectiveness. Current evidence supports the feasibility but not the superiority of nurse-led SDM. Well-designed randomised controlled trials are needed to establish comparative effectiveness and cost-effectiveness before recommending widespread integration of nurse-led SDM into lung cancer screening programmes.

In the context of declining total fertility rates, many governments are seeking the optimal blend of policy interventions to encourage childbirth. Scholars have mapped how pronatal policy agendas are shaping social policies, yet there has been less attention on how such agendas shape health policies. This review will map and synthesize the evidence on how pronatal policies affect sexual and reproductive healthcare.

A scoping review will be conducted using two searches. One search will identify relevant peer-reviewed papers in Medline, EMBASE, social policy and practice, global health and Web of Science databases. A second search will identify relevant grey literature from Overton and Policy Commons databases. Sources will be managed using Rayaan software and studies selected based on specified inclusion criteria. Data will be extracted using a customised extraction form, mapped and subsequently synthesised using narrative approach.

This review will be disseminated through a peer-reviewed manuscript and conference presentations. Ethics and patient engagement are not required for a scoping review.

To evaluate health outcomes and identify risk factors for reinfection and persistent symptoms among COVID-19 survivors 4 years after hospital discharge.

Longitudinal cohort study.

Two hospitals in Wuhan, China.

1076 COVID-19 survivors discharged from hospital.

Self-reported symptom questionnaire, Chronic Obstructive Pulmonary Disease Assessment Test, Hospital Anxiety and Depression Scale and Checklist Individual Strength (CIS) fatigue subscale. Long covid was defined according to WHO criteria.

Median age was 58 years and 50.2% were male. Reinfection during December 2022–April 2023 occurred in 36.1%; 21 developed pneumonia and 14 required hospitalisation. At least 12 months after reinfection, 12.1% reported sequelae compared with 46.9% after the initial infection. At 4 years, 16.7% reported long covid symptoms, commonly fatigue, chest tightness, cough and dyspnoea. In multivariable analysis, risk factors for abnormal fatigue (CIS ≥27) included age (OR 1.020, 95% CI 1.007 to 1.034; p=0.003), reinfection (OR 2.393, 95% CI 1.708 to 3.352; p

At 4 years post discharge, symptom burden was lower than at earlier follow-up time points for most survivors. Reinfection and older age were associated with persistent symptoms.

While adverse childhood experiences (ACEs) have been consistently linked to poorer cognitive outcomes in later life, far less is known about ACEs’ contribution to dementia and cognitive ageing risk in low-income and middle-income countries (LMICs), despite their growing and disproportionate share of global Alzheimer’s disease and related dementias (ADRD) burden. This study aimed to systematically review existing evidence on the association between individual ACEs and cognitive outcomes among adults aged 40 years and older in LMIC settings.

Systematic review and narrative synthesis.

We searched Medline, Embase, PsycINFO and CINAHL from the inception of each database to January 2026.

Observational studies examining the association between individual ACEs and cognitive outcomes among adults aged 40 and older in LMICs.

Two reviewers independently screened each record, assessed risk of bias using the Joanna Briggs Institute critical appraisal tool and extracted data. Results were illustrated using descriptive forest plots and a narrative synthesis.

Our systematic review included 14 studies, primarily from upper-middle-income countries, that assessed the relationship between individual ACEs and cognitive impairment (n=4) and function (n=10). 10 studies reported significant associations between ACEs and poorer cognitive function and increased risk of cognitive impairment. No study assessed the association between ACEs and ADRD. Parental death, neglect and mental health issues in the family showed consistent associations with cognitive outcomes, whereas experiencing hunger and poor health in childhood showed inconsistent associations.

Our review corroborated evidence from high-income countries that exposure to ACEs is associated with a long-term risk of poorer cognitive outcomes among older populations in LMICs. However, the available literature remains limited, with most studies originating from upper-middle-income countries, few examining cognitive impairment and none assessing ADRD. These findings underscore substantial gaps in knowledge and highlight the need for research across diverse LMIC settings to clarify the role of broader psychosocial and contextual childhood experiences in shaping cognitive ageing and dementia risk.

Each year, an estimated 1700 children should be diagnosed with cancer in western Kenya, with leukaemia making up nearly one-third of cases. However, far fewer are actually diagnosed, highlighting significant delays or errors in diagnosis. Flow cytometry, which the WHO considers essential for leukaemia diagnosis, remains underused across sub-Saharan Africa due to high costs, outdated equipment and a lack of trained personnel. In Kenya, decades-old cytometers have been adapted for leukaemia detection, but these systems are now outdated. Newer platforms, such as simplified single-tube multiparametric assays, provide a scalable and sustainable alternative. This study presents a protocol to evaluate the accuracy of diagnosis and the potential for implementing a streamlined flow cytometry assay using peripheral blood, supported by a regional educational initiative.

This prospective, mixed-methods implementation study has three aims: (1) to assess the concordance between the Beckman Coulter ClearLLab 10C gold standard 4-tube assay and the streamlined ClearLLab LS 1-tube assay using paired bone marrow and peripheral blood samples; (2) to evaluate the feasibility of peripheral facility referrals and transport logistics with couriered peripheral blood samples from referring sites across western Kenya; and (3) to measure training effectiveness and knowledge gain through a multimodal educational programme using the Project ECHO (Extension for Community Healthcare Outcomes) model. Up to 300 patients at Moi Teaching and Referral Hospital in Eldoret, Kenya, will be enrolled in Aim 1. A separate sample of 100 patients from peripheral facilities will be included in Aim 2. Surveys, knowledge assessments and structured interviews will be used to evaluate training impact under Aim 3. Diagnostic concordance, sensitivity, specificity and knowledge gain will be measured through appropriate quantitative and qualitative methods.

The protocol has received approval from institutional ethics committees at Moi University, MTRH and Indiana University. De-identified data will be analysed and shared through peer-reviewed publications, stakeholder presentations and educational platforms.

Limited male engagement in HIV prevention and care is a global challenge more pronounced in sub-Saharan Africa (SSA) contributing to ongoing transmission. However, peer network interventions show promise in improving engagement.

To map and synthesise evidence on peer network interventions for HIV prevention and care among men in SSA, with a focus on the types of strategies used, populations reached and how these interventions address cultural, social and structural barriers across the HIV care cascade.

Scoping review of peer-reviewed literature, conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

Community and facility-based HIV prevention and care settings across multiple countries in SSA.

Populations included men having sex with men, men in key occupational groups (fishermen, truck drivers), adolescents and young people, and men living with HIV. Studies not conducted in SSA, not peer-reviewed or not focused on male peer networks were excluded.

Peer network interventions included peer education, peer navigation, HIV self-testing (HIVST) distribution, adherence support groups, disclosure and stigma-reduction counselling, technology-enabled peer support (SMS and social media) and community-based antiretroviral therapy (ART) delivery. Intervention duration and intensity varied across studies.

Primary outcomes included HIV testing uptake, linkage to care, ART initiation, adherence, retention in care and viral suppression. Secondary outcomes included stigma reduction, disclosure and engagement among hard-to-reach male populations.

We conducted a review of literature published between November 2013 and November 2024, searching PubMed, Web of Science, Scopus and Cochrane databases. Studies were included if they examined peer network approaches in HIV prevention and care among men in SSA.

A total of 905 records were identified, of which 75 studies met the inclusion criteria. Peer network interventions were implemented across diverse SSA contexts and male populations. Strategies such as peer-led education, social diffusion models, HIVST distribution and technology-enabled peer support consistently improved HIV testing uptake, linkage to care, ART initiation and adherence. Contextually tailored interventions such as community-based outreach addressing occupational risk environments and economic vulnerabilities were particularly effective in engaging men traditionally underserved by facility-based services. However, challenges persisted, including variable linkage to care following HIVST and sensitivity to user costs.

Peer-led interventions in HIV care for men in SSA effectively address cultural, social and structural barriers, improving testing, ART adherence and viral suppression. Tailored, technology-enhanced and community-based approaches ensure equitable HIV prevention and treatment outcomes, despite challenges like linkage to care.

A significant number of women die from pregnancy and childbirth complications globally, particularly in low and middle-income countries. Receiving at least four antenatal care (ANC) visits is important in reducing maternal and perinatal deaths. However, few studies have investigated the factors linked to the completion of ≥4 ANC visits in Nepal.

To investigate factors associated with attending ≥4 ANC visits in Sarlahi district of southern Nepal.

A secondary analysis was conducted on data from the Nepal Oil Massage Study (NOMS), a cluster-randomised, community-based longitudinal pregnancy trial including 34 village development committees. We investigated the associations between attendance of ≥4 ANC visits and socioeconomic, demographic, morbidity and pregnancy history factors using logistic regression; generalised estimating equations were used to account for multiple pregnancies per woman. All pregnancies resulting in a live birth (LB) (n=31 867) were included.

Attendance of ≥4 ANC visits.

31.4% of those pregnancies received 4+ ANC visits. Significant positive associations included socioeconomic factors such as participation in non-farming occupations for women (OR=1.52, 95% CI 1.19 to 1.93), higher education (OR=1.79, 95% CI 1.66 to 1.93) and wealth quintile (OR=1.44, 95% CI 1.31 to 1.59), nutritional status such as non-short stature (OR=1.17, 95% CI 1.07 to 1.27), obstetric history such as adequate interpregnancy interval (OR=1.31, 95% CI 1.19 to 1.45) and prior pregnancy but no LB (OR=2.14, 95% CI 1.57 to 2.92), symptoms such as vaginal bleeding (OR=1.35, 95% CI 1.11 to 1.65) and awareness of the government’s conditional cash transfer ANC programme (OR=2.26, 95% CI 2.01 to 2.54). Conversely, identifying as the Shudra caste (OR=0.56, 95% CI 0.47 to 0.67), maternal age below 18 or above 35 (OR=0.81, 95% CI 0.74 to 0.88; OR=0.77, 95% CI 0.62 to 0.96), preterm birth (OR=0.41, 95% CI 0.35 to 0.49), parity ≥1 (OR=0.66, 95% CI 0.61 to 0.72) and the presence of hypertension during pregnancy (OR=0.79, 95% CI 0.69 to 0.90) were associated with decreased likelihood of attending ≥4 ANC visits.

These findings demonstrate the importance of socioeconomic factors, including education, caste, wealth and occupation in completion of ≥4 ANC visits. In addition, biological factors including birth spacing, pregnancy complications and nutrition are important. The association with awareness of the government’s conditional cash transfer programme is a motivation for a full evaluation of whether expanding that programme might improve prenatal care.

High-quality early childhood education can fundamentally alter children’s long-term education, earnings and well-being. In low-resourced settings, children’s development is hampered by undernutrition, poverty and limited access to services. This study will generate high-quality evidence on child development from children who both attend and do not attend daycare across informal settlements in Kenya by (1) examining the relationship between child development, nutritional status and household characteristics using a large, community-based sample and (2) measuring the impact of exposure to improvements in childcare quality on child development and nutritional status.

We combine a cross-sectional observational study of child development and anthropometrics among approximately 4700 children aged 0–5 across 11 counties in Kenya with a cluster randomised controlled trial that measures the impact of improved daycare quality on these outcomes. We use International Development and Early Learning Assessment to measure child development and record child height and weight to measure height-for-age and weight-for-height z-scores. Primary analyses will (1) estimate associations between child development outcomes and nutritional status using multivariable regression models, adjusting for prespecified covariates; and (2) examine differences in outcomes between children attending daycares in communities exposed to quality improvements and children attending daycares in control communities. Subgroup analyses will examine heterogeneity by child sex and daycare participation.

The Strathmore University Institutional Scientific and Ethical Review Committee (SU-ISERC) has provided ethical review for this study, with initial approval SU-ISERC1602/23. This study has also received IRB approval from The Ohio State University (#2023B0300). Written informed consent will be obtained from caregivers before participation. We will disseminate findings through peer-reviewed publications, policy briefs and presentations to local stakeholders, and we will publish de-identified data and replication code on a public repository.

Diarrhoeal illnesses remain a leading cause of morbidity and mortality worldwide. Understanding when and where individuals seek healthcare is essential for accurately assessing disease burden and improving access to appropriate care. We conducted a meta-synthesis of qualitative research examining barriers and facilitators to care-seeking for diarrhoeal illness among individuals and caregivers of children.

We systematically reviewed qualitative studies examining the motivations for seeking care for diarrhoeal illness and conducted a thematic analysis to synthesise findings across studies.

PubMed, Embase, Web of Science and Global Index Medicus were searched through 3 September 2024.

We included qualitative studies that used interviews and/or focus group discussions to examine care-seeking decisions for diarrhoeal illness.

Two independent reviewers assessed studies for eligibility, extracted study information and coded factors influencing care-seeking decisions. The two researchers then independently created thematic trees based on patterns in the coded data and, through discussion with the full research team, synthesised findings into a thematic framework.

In total, 47 studies met our inclusion criteria, 36 of which focused on caregiver decision-making for children with diarrhoea in low- and middle-income countries. Our meta-synthesis identified several key factors that influenced whether and when individuals sought care. Sociocultural norms, including locally held beliefs about disease causation, were frequently cited as influencing decisions to seek or delay formal care. Additional barriers included long travel distances to health facilities, transportation costs, limited trust in healthcare providers, negative feelings and inconsistent availability of care. Conversely, episodes perceived as severe were more likely to prompt care-seeking outside the home.

These findings highlight the importance of contextually grounded interventions that improve physical and financial access to care, foster trust in healthcare providers through consistent and effective service delivery and strengthen community engagement around recognising signs of severe illness and the potential benefits of timely treatment. They also underscore the need for future studies to define diarrhoea in locally relevant terms and to clearly define sources of care-seeking, as variation in these definitions can limit our full understanding of who is affected and how individuals respond to illness.
