The human gut microbiome, consisting of bacteria, archaea, fungi, and viruses, influences various physiological processes of the body. The gut microbiome composition is shaped by factors such as diet, geography, and antibiotic use. Malaria has been a global health challenge over the years, especially in low- and middle-income countries. This study investigated how asymptomatic malaria infection altered gut microbial communities in Ghanaian children, offering insights for novel malaria control strategies. Standard aseptic phlebotomy procedures were employed to collect venous blood samples for Plasmodium species detection. The gut microbial community was profiled by sequencing the 16S rRNA V4 region, and sequence data were processed using the DADA2 pipeline in R. Asymptomatic malaria infections were predominantly mixed with P. falciparum and P. malariae. Microbiome analysis revealed that Firmicutes and Bacteroidetes comprised nearly 70% of the total microbial population. Asymptomatic individuals showed a decrease in Firmicutes abundance from 52.5% to 44.0% and an increase in Bacteroidetes from 34.7% to 45.6%. There was also a slight increase in the abundance of Proteobacteria from 3.0% to 4.8%. At the genus level, Prevotella_9 was the most abundant and exhibited the highest variability in the infected groups. The Alloprevotella and Streptococcus genera increased in both infected groups, but Escherichia-Shigella was significantly elevated in only those with mixed infections. Faecalibacterium significantly declined in asymptomatic malaria-infected individuals compared to healthy controls, with variability further reduced in mixed infections. Beta-diversity analysis indicated a significant effect of malaria status on microbial composition (PERMANOVA, p 

Effective Coverage of Maternal and Newborn Health Services in Sub-Saharan Africa: What distinguishes high from medium and low performers?

by Ayelign Mengesha Kassie, Solomon Woldeyohannes, Anteneh Zewdie, Eskinder Wolka, Yibeltal Assefa

Background

Effective coverage (EC) has emerged as a better measure of service coverage, in the past decades, compared to the simple crude coverage measures. It represents the proportion of a population in need of a service that successfully receives it with sufficient quality to achieve the intended health benefits. Nevertheless, EC in maternal and newborn health (MNH) services are significantly variable across and within countries. Therefore, this study aimed to identify the societal and health system factors that can explain why some countries are having higher EC of MNH services than others in Sub-Saharan Africa (SSA).

Methods

A mixed-method case study design was employed with inclusion of document review. Effective coverage rates were estimated using countries demographic and health survey (DHS) datasets. Two countries were then selected for each MNH service domain from each performance category, high, medium, and low, for further analysis of explanatory factors. Data sources included DHS and health facility survey summary reports, the Global Health Expenditure Database, and TheGlobalEconomy.com.

Results

We found huge variation in EC of MNH services across countries in SSA. The scores range from 7% in Ethiopia to 64% in Liberia for 4+ ANC visits, 9% in Ethiopia and Nigeria to 81% in Rwanda for institutional delivery, 3% in Ethiopia to 77% in Gambia for PNC mothers, and 1% in Ethiopia to 68% in South Africa for PNC newborns. These discrepancies are highly likely influenced by multilevel health system and societal factors. High-performing countries in EC of MNH services have higher service availability and readiness scores than medium- and low-performing ones. For instance, Ghana and Liberia scored 83% and 84%, respectively, for tracer indicators of ANC service availability, compared to 43% in Ethiopia and 64% in Malawi. Similar pattern is observed between the selected countries EC estimates of MNH services and their health service specific readiness index scores. In addition, they also have favourable societal factors including high proportion of women attending primary and/or more school levels, better mass media and internet access, and relatively lower political instability indexes. Low-performing countries like Ethiopia and Nigeria had complex futures including having low health service availability and readiness scores and unfavourable societal factors including in women’s education, and internet and mass media access. Furthermore, the two countries had weakest average political stability index that hinders the utilization and delivery of MNH services.

Conclusions

The findings revealed that better health service availability and readiness, strong healthcare financing, favourable societal factors and having a relatively stable political index are critical in determining countries performance in EC of MNH services. Therefore, countries, particularly low performers in EC of MNH services need to learn from positive outliers in improving EC of MNH services. Strengthening existing health facilities with better staffing, training, and resources is crucial beyond merely expanding new ones.

Helpful or harmful? How cancer beliefs and information seeking relate to depression in U.S. adults

by Ama Gyesiwaa Quansah, Helena Baffoe, Solomon Eshun

This study examined how cancer-related beliefs, information-seeking behaviors, and discussions about health with family or friends relate to depressive symptoms (PHQ-2 ≥ 3) among U.S. adults, using data from the 2024 Health Information National Trends Survey (HINTS 7; unweighted N = 6,826). Associations were estimated using survey-weighted logistic regression with jackknife replicate weights, adjusting for sociodemographic factors and personal or family cancer history; results are reported as adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Weighted estimates indicate that approximately 15.5% of respondents screened positive for depression. Fatalistic beliefs, particularly the views that everything causes cancer (OR = 1.86; 95% CI: 1.39–2.48), prevention is not possible (OR = 1.69; 95% CI: 1.25–2.28), and cancer automatically means death (OR = 1.75; 95% CI: 1.31–2.34), were significantly associated with higher odds of screening positive for depression. In contrast, neither cancer information seeking (OR = 1.12; 95% CI: 0.83–1.51) nor discussions about health with family or friends (OR = 0.90; 95% CI: 0.62–1.30) showed a significant independent association with depression. In moderation analyses, discussions about health with family or friends weakened the positive association between each fatalistic belief and depression, but these interaction effects were not statistically significant. Sensitivity analyses using multiple imputation for missing data and restricting the analyses to respondents without a personal cancer history produced consistent results. Theoretical and practical implications of these findings are discussed.

Multidrug resistance patterns and carbapenemase production among Gram-negative bacteria causing healthcare-associated infections in hospitalized patients at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia

by Kindu Alem, Mucheye Gizachew, Mulat Dagnew, Worku Ferede, Solomon Belay, Baye Gelaw, Feleke Moges

Background

Klebsiella pneumoniae, Acinetobacter species, and Pseudomonas aeruginosa are priority pathogens identified by the World Health Organization that have emerged as major causes of healthcare-associated infections. Their increasing resistance to multiple antimicrobial agents poses significant challenges to clinical management and infection control efforts.

Objective

This study aimed to determine the prevalence, associated risk factors, antimicrobial resistance patterns, and carbapenemase production of K. pneumoniae, Acinetobacter spp., and P. aeruginosa among hospitalized patients with suspected bloodstream, urinary tract, and surgical site healthcare-associated infections at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.

Methods

A hospital-based cross-sectional study was conducted from August 2024 to June 2025 among 477 patients suspected of bloodstream, urinary tract, or surgical site healthcare-associated infections. Socio-demographic and clinical data were collected using a semi-structured questionnaire. Blood, urine, and wound/pus specimens were aseptically collected and inoculated on MacConkey, blood, and cysteine lactose electrolyte-deficient agar following standard microbiological techniques. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disc diffusion method on Mueller-Hinton agar according to Clinical and Laboratory Standards Institute guidelines. Data were analyzed using SPSS version 27. Bivariate and multivariate logistic regression analyzes were used to identify factors associated with healthcare-associated infections. P value  Results

Among the 477 patients, 118 (24.7%) developed healthcare-associated infections caused by K. pneumoniae, Acinetobacter spp., and P. aeruginosa, with culture positivity rates of 14.9%, 4.8%, and 5%, respectively. Significant associated factors included age under five (AOR = 13.260, p K. pneumoniae, 69.6% of Acinetobacter spp., and 58.3% of P. aeruginosa isolates. Carbapenemase production occurred in 92%, 77.8%, and 57.1% of these carbapenem-resistant isolates, respectively. Amikacin, meropenem, and ciprofloxacin were the most effective antimicrobials, whereas chloramphenicol was effective only against K. pneumoniae.

Conclusion

This study showed high prevalence of multidrug resistance and carbapenemase production among K. pneumoniae, Acinetobacter spp., and P. aeruginosa in the study area, highlighting the urgent need to strengthen infection prevention and control measures and to promote antimicrobial stewardship programs.

Support for Transgender and Nonbinary Individuals Seeking Vaginoplasty (STRIVE) study: protocol for a national randomised pragmatic trial

Por: Sage · L. · Hart · E. · Meyer · N. · Hnilicka · O. · Penkin · A. · Poteat · T. C. · Aguayo-Romero · R. · Comstock · B. A. · STRIVE Publications Committee · Dy · G. W. · Blasdel · Corman · Deutsch · Gallo · Gore · Marsiglio · Sevelius · Solo
Introduction

Transgender and gender-diverse individuals often face significant barriers to accessing gender-affirming care, such as hormones and/or surgery, leading to poorer mental health, lower quality of life, and higher rates of substance use and suicidal ideation. Vaginoplasty, the most commonly sought genital gender-affirming surgery (GGAS), is desired by over half of all trans women but has been performed in only a minority. This is due largely to limited surgeon availability and long wait times. Peer support has been shown to improve health outcomes and reduce stigma in marginalised populations, including trans communities, but has never been studied for efficacy during the perioperative period of GGAS. Building on priorities identified by multi-stakeholder engagement from the Transgender & Non-Binary Surgery Allied Research Collective, the Support for Transgender and Nonbinary Individuals Seeking Vaginoplasty (STRIVE) study aims to evaluate the efficacy of a centralised peer support and education intervention for patients seeking vaginoplasty, addressing a critical gap in perioperative care.

Methods and analysis

The STRIVE Study is a pragmatic, multi-site randomised controlled trial enrolling trans adults seeking full depth vaginoplasty. Participants are randomised to one of two arms; enhanced usual care, or a facilitated group intervention. The primary outcome is coping self-efficacy at 6 months, with a secondary outcome of surgical readiness. Primary analysis uses an intention-to-treat approach with linear mixed effects modelling, adjusting for selected baseline values and site. The feasibility evaluation data collected via qualitative interviews will be analysed thematically.

Ethics and dissemination

Approvals were granted by the primary site’s Institutional Review Board on 10 May 2024 (STUDY00026957). The trial was registered on 24 May 2024. Results will be published in open access journals and made available to community members in plain language formats.

Adult survivors of sickle cell disease, transfusion-dependent beta-thalassaemia and childhood acute leukaemia in England: protocol for a mixed methods data linkage and health-related quality of life survey study

Por: Ahmed · K. · Holloway · I. · Absolom · K. · Mason · S. J. · Mujica-Mota · R. · Gkountouras · G. · Martin · A. · Flannery · T. · Richards · M. · Astwood · E. · Ackroyd · S. · Greystoke · B. · Greenfield · D. M. · Hill · Q. · James · B. · Kwok- Williams · M. · Murray · R. D. · Samuelson · C
Introduction

Recent advances in treatment and care have improved survival rates for children and young adults with severe blood disorders such as sickle cell disease (SCD), transfusion-dependent beta-thalassaemia (TDT) and acute leukaemia. However, their quality of life and reproductive and psychosocial outcomes are not yet well studied. For SCD and TDT, robust survival data are mainly limited to North America. Thus, there is a need to fill these knowledge gaps to guide improvements in care, address unmet clinical needs and rigorously assess the efficacy of emerging novel therapies.

Methods and analysis

This is an observational population-based mixed-methods study of individuals diagnosed with SCD, TDT or acute leukaemia when under the age of 18 in England, involving a data linkage component and a patient-reported outcomes measures survey. Data linkage-eligible participants will be identified from national and regional databases, including the Hospital Episode Statistics, Yorkshire Specialist Register of Cancer in Children & Young People and the National Congenital Anomaly and Rare Diseases Registration Service. Data linkage will be processed within the NHS England and the University of Leeds’ secure, trusted research environments. Data will be accessed without consent under section 251 and approval by the confidentiality advisory group. It will assess survival rates for SCD and TDT as well as clinical, educational and mental health outcomes for SCD, TDT and acute leukaemia diagnosed in childhood.

Survey-eligible participants for SCD, TDT and acute leukaemia cohorts will be checked for their suitability to participate by the North of England clinical care teams. An NHS-approved survey provider will facilitate data checks with the NHS National Data Opt-Out Service. Consent is required for participation in the survey and for subsequent data linkage to existing databases. Surveys are conducted in various formats (online, paper and phone), with reminders sent after 21 days. The survey will assess quality of life and psychosocial and reproductive outcomes. Participants can withdraw at any time, and support is available via telephone helplines.

Ethics and dissemination

The study has received ethical and information governance approval from the Health Research Authority (Reference 24/YH/0186) and the Confidentiality Advisory Group (CAG 24/CAG/0138) to process identifiable data without consent. Study results will be available to patients, physicians, researchers, stakeholders and others through open-access publishing, results sharing via media platforms and presentations at conferences and meetings.

Work-related musculoskeletal disorder among midwives, a threat for maternity care

by Osman Yimer Mohammed, Kerstin Erlandsson, Tewodros Seyoum, Solomon Hailemeskel, Lemma Derseh, Helena Lindgren

Background

Work-related musculoskeletal disorder is a limiting, painful condition that affects the muscular, skeletal, articular, and nervous tissues of the body. The condition is mainly associated with poor working conditions and awkward body positions. Health professionals, including midwives, are among the most affected workforce globally. The condition affects the health of the professionals and the quality of care that professionals are expected to provide. However, there is a scarcity of information on the magnitude of the condition, its effect on midwifery practice, and associated factors. Objectives: This study aimed to assess the magnitude of work-related musculoskeletal disorder, its effect on midwifery practice, and associated factors among midwives in North Shoa Zone, Amhara Regional State, Ethiopia.

Method

An institution-based cross-sectional study assessed the magnitude of work-related musculoskeletal disorder (WRMSD), the effect on midwifery practice, and associated factors. The Nordic Musculoskeletal Disorder Scale was used to assess the presence of WRMSDs in the nine regional body parts and its effect. A stepwise backward elimination logistic regression model was used, and significant association was declared at a p-value of less than 0.05.

Results

A total of 473 (252 (53.3%) female and 221 (46.7%) male) midwives participated in this study. Overall, in the last 12 months, 355 (75.05%, 95% CI: 71.15% − 78.95%) midwives were affected by WRMSD, which was seen in any one of the nine regional body parts. About 45% (162) of them reported being unable to perform their daily tasks while they were affected, and 27% (96) of them sought treatment for their condition. The lower back was the most affected axial body part, reported by 300 (63.4%, 95% CI: 59% − 68%) midwives. Working in awkward or uncomfortable positions was significantly associated with the development of WRMSD (AOR: 1.81, 95% CI: 1.15–2.87). Similarly, awkward positions significantly affected the development of area-specific WRMSD in the lower back, upper back, neck, and limbs. Working in the same position for a longer time, seeing clients daily, and moving heavy objects were among the risk factors associated with developing area-specific WRMSD among midwives.

Conclusion

The magnitude of work-related musculoskeletal disorders is high among midwives, and a significant number of them were unable to perform their daily tasks. The lower and upper back are the most commonly affected areas. Working in uncomfortable positions and attending to large clients daily were common risk factors. Therefore, training midwives about safe working positions and reducing the workload is commendable.

Volumetric MRI and FDG-PET hypometabolism biomarkers of frontotemporal dementia: protocol for a systematic review and meta-analysis

Por: Solomon · T. J. · Antonic-Baker · A. · Romero · L. · Sinclair · B. · OBrien · T. J. · Vivash · L.
Introduction

Frontotemporal dementia (FTD) remains challenging to diagnose owing to the marked clinical heterogeneity associated with the disease. This heterogeneity stems from the complex interplay of various clinical phenotypes, genetic mutations and underlying neuropathologies, such as TDP-43 and tau proteinopathies. Currently, there is no single confirmed biomarker that can reliably diagnose disease, specifically disease stage, disease subtype and underlying neuropathology. Recent research has indicated that neuroimaging techniques hold the most promise for the discovery of FTD biomarkers. We propose a protocol for a systematic review and meta-analysis to identify MRI and fluorodeoxyglucose positron emission tomography (FDG-PET) biomarkers associated with clinical, genetic and pathological subtypes of FTD. We aim to address the following research questions: can regional MRI volumetry and FDG-PET hypometabolism differentiate (1) FTD patients from healthy controls; (2) sporadic cases of FTD from healthy controls; (3) genetic cases of FTD (MAPT, GRN, and C9orf72 mutations); and (4) underlying neuropathology, specifically discriminating between tau- and TDP-43-based FTD?

Methods

Literature searches will be performed across three databases: Ovid Medline, Ovid Embase and Web of Science. Publications that have fewer than five participants, are non-human-based, not written in the English language or contain unpublished data will be excluded. Two independent investigators will screen and subsequently evaluate which publications to include. Should any disagreements arise, a third investigator will settle the discrepancy. After the random-effects meta-analysis has been used to extract and pool the data, I2 analysis will be used to quantify heterogeneity.

Ethics and dissemination

Ethics approval will not be required for this research. On completion, the systematic review and meta-analysis will be published in a peer-reviewed journal.

Introduction

Streptococcus pneumoniae serotype 3 (SPN3) remains a significant contributor to invasive pneumococcal disease globally, despite its inclusion in widely administered vaccines. The next generation of pneumococcal vaccines may confer better protection against this serotype, reducing disease burden. We describe an ethically approved protocol for a double-blind randomised controlled trial assessing the impact of VAXNEUVANCE (15-valent pneumococcal conjugated vaccine (PCV15)) and 0.9% saline (placebo) on the acquisition, density and duration of SPN3 carriage using a controlled human infection model.

Methods and analysis

Healthy adults aged 18–50 years will be randomised 1:1 to receive PCV15 or placebo. Participants will be considered enrolled on the trial at vaccination. One month following vaccination, all participants will be intranasally inoculated with SPN3. Following inoculation, participants will be followed up on days 2, 7, 14 and 28 to monitor safety, SPN3 colonisation status, density and duration, as well as immune responses. The primary endpoint of the study is to assess the rate of SPN3 acquisition between vaccinated and unvaccinated participants defined by classical microbiological methods. Secondary endpoints will determine the density and duration of SPN3 colonisation and compare the immune responses between study groups. An exploratory cohort of 5 participants will be asked to consent to a nasal biopsy procedure during a screening visit and a second nasal biopsy 28 days after PCV15 vaccination. This cohort will only receive PCV15 and will not be challenged. Through this exploratory cohort, we will explore gene expression changes induced by PCV15 vaccination and their visualisation (spatial location) within the nasal tissue.

Ethics and dissemination

This protocol has been reviewed by the sponsor, funder and external peer reviewers. The study is approved by the NHS Research and Ethics Committee (Reference: 24/SC/0388) and by the Medicines and Healthcare Products Regulatory Agency (Reference: CTA 21584/0485/001-0001).

Motor learning principles reported in stroke trials of upper limb task-oriented training: a scoping review

Por: Durairaj · S. · Sardesai · S. · Solomon · J. M. · Levin · M. F.
Objective

Upper limb task-oriented training (UL-TOT) is a complex intervention in which practice conditions related to motor learning principles are applied to enhance upper limb motor recovery after stroke. The Template for Intervention Description and Replication guidelines suggest that detailed reporting of a complex intervention is essential in published studies. Therefore, this review aimed to determine the extent to which practice conditions related to motor learning principles were reported in UL-TOT stroke clinical trials.

Methods

A comprehensive search was done using appropriate keywords in PubMed, CINAHL, Web of Science, Scopus and Cochrane databases from 2000 to 2024. Two reviewers independently conducted title screening, abstract screening and full-text evaluation based on the inclusion and exclusion criteria. A third reviewer resolved the conflicts between the two reviewers during the screening process. Finally, the articles that fulfilled the criteria were included for data extraction.

Results

23 802 studies were retrieved, and 166 studies were retained. Practice conditions such as practice variability (98%), dosage (97%) and movement complexity (96%) were reported more frequently, task selection for practice (75%), challenging and progressive task practice (76%) were reported frequently, practice order (57%), practice distribution (51%), feedback type (44%) and timing (44%) were reported occasionally. Feedback frequency (37%) was reported rarely.

Conclusions

Practice conditions such as practice variability, dosage, movement complexity, task selection, challenging and progressive task practice were reported consistently, while practice distribution, order and feedback were reported inconsistently. Developing a standard checklist for practice conditions related to motor learning principles can improve detailed reporting of practice conditions in future UL-TOT stroke clinical trials. This can help researchers replicate and reliably implement the intervention in specific populations and build on and create more effective interventions.

Objective

Thanks to the introduction of recent national guidelines for treating herpes simplex virus (HSV) encephalitis, health outcomes have improved. This paper evaluates the health system costs and the health-related quality of life implications of these guidelines.

Design and setting

A sub-analysis of data from a prospective, multi-centre, observational cohort ENCEPH-UK study conducted across 29 hospitals in the UK from 2012 to 2015.

Study participants

Data for patients aged ≥16 years with a confirmed HSV encephalitis diagnosis admitted for treatment with aciclovir were collected at discharge, 3 and 12 months.

Primary and secondary outcome measures

Patient health outcomes were measured by the Glasgow outcome score (GOS), modified ranking score (mRS) and the EuroQoL; healthcare costs were estimated per patient at discharge from hospital and at 12 months follow-up. In addition, Quality Adjusted Life Years (QALYs) were calculated from the EQ-5D utility scores. Cost–utility analysis was performed using the NHS and Social Care perspective.

Results

A total of 49 patients were included; 35 were treated within 48 hours, ‘early’ (median (IQR) 8.25 [3.7–20.5]) and 14 were treated after 48 hours ‘delayed’ (median (IQR) 93.9 [66.7–100.1]). At discharge, 30 (86%) in the early treatment group had a good mRS outcome score (0–3) compared with 4 (29%) in the delayed group. According to GOS, 10 (29%) had a good recovery in the early treatment group, but only 1 (7%) in the delayed group. EQ-5D-3L utility value at discharge was significantly higher for early treatment (0.609 vs 0.221, p

Conclusions

This study suggests that early treatment may be associated with better health outcomes and reduced patient healthcare costs, with a potential for savings to the NHS with faster treatment.

Early supplementation for cows milk allergy prevention in breastfed infants in Poland (ESCAPE-PL): a protocol for randomised controlled trial

Por: Horvath · A. · Wesolowska · A. · Strozyk · A. · Bzikowska-Jura · A. · Ambrozej · D. · Dumycz · K. · Feleszko · W. · Szajewska · H.
Introduction

Current recommendations for early introduction of cow’s milk proteins in infants who cannot be breastfed vary and are inconsistent due to a lack of clear evidence. We aim to assess whether early supplementation with various nutritional interventions, including cow’s milk formula (CMF), amino acid formula (AAF), donor human milk (DHM) or high-pressure processed ‘pascalised’ DHM (DHM-P) is effective for the primary prevention of cow’s milk allergy (CMA) in breastfed neonates.

Methods and analysis

We will perform an open-label randomised, controlled, head-to-head trial with four parallel arms in three Polish study centres (Warsaw). 1000 healthy full-term newborns of mothers eager to exclusively breastfeed will be allocated to receive early supplementation with one of four nutritional interventions: CMF, AAF, DHM or DHM-P. All children will receive 10 mL of each intervention per day for the first 3 days of life; exclusive breastfeeding will be recommended. However, if any supplementation in addition to the breastfeeding is needed, the assigned nutritional intervention will be provided until 4 months of age. The primary outcome is a cumulative incidence of CMA confirmed by open oral food challenge at 4–6 months and 12 months of age. Secondary outcomes include an incidence of sensitisation to cow’s milk protein; a total score in the Cow’s Milk Related Symptom Score; the percentage of children with acquired tolerance to cow’s milk, feeding difficulties and exclusively and predominantly breastfed; an incidence of atopic dermatitis, allergic rhinitis and wheezing; growth; compliance and adverse events. The level of immunomodulatory factors in maternal milk and its nutritional component analysis will also be performed.

Ethics and dissemination

The ethics committee of the Medical University of Warsaw, Poland, approved this protocol (KB/61/2023). The results of this study will be submitted to a peer-reviewed journal no later than 1 year after data collection. The abstract will be presented at relevant national and international conferences.

Trial registration number

NCT06652698.
