This systematic review aims to synthesise current evidence on gut microbiome profiles among children with sickle cell disease (SCD), assess the influence of analgesic and antibiotic use, and explore the contributions of environmental factors on their gut microbiota diversity. Through identification of consistent microbial patterns and gaps in the existing literature, this review will provide vital insight into potential microbiome-targeted strategies for improving health outcomes in paediatric SCD care.

Studies describing the gut microbiota among paediatric SCD human subjects (

Ethical approval will not be required as this is a systematic review of published data. The findings will be disseminated through publications in peer-reviewed journals and presentations at relevant scientific conferences.

To identify stakeholder perceived challenges and facilitators for implementing a clean fuel and clean stove intervention to reduce household air pollution and hypertension in Lagos, Nigeria.

Qualitative study guided by the Exploration and Preparation phases of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, using focus group discussions and in-depth semi-structured interviews with inductive and deductive thematic analysis.

Peri-urban communities across the five administrative divisions of Lagos State, Nigeria.

128 stakeholders from 32 communities, including community, religious, market and youth leaders, primary healthcare staff, and household decision makers. Approximately half were female.

This was a pre-implementation needs assessment that included demonstrations of the clean stove and fuel.

Thematic domains describing barriers and enablers to adoption and implementation, mapped to EPIS inner, outer, and bridging factors.

Stakeholders reported barriers that included stove stacking, upfront stove cost, concerns about long-term fuel price and availability, equipment durability and maintenance, safety, mistrust of new technology, and uncertainty about stove performance for dishes requiring high heat and long cooking times. Reported facilitators included payment flexibility and subsidies, opportunities to test the stove, perceived benefits of cleaner and faster cooking with less soot, endorsement by community leaders, and interest in local retail and distribution to improve access.

Implementation planning for clean fuel and clean stove programmes should address affordability, reliable fuel supply chains, durability and service, culturally relevant cooking needs, and trust building through community leadership. These findings inform adaptation strategies for scale-up in similar low-resource settings.

Encephalitis is brain parenchyma inflammation, frequently resulting in seizures which worsens outcomes. Early anti-seizure medication could improve outcomes but requires identifying patients at greatest risk of acute seizures. The SEIZURE (SEIZUre Risk in Encephalitis) score was developed in UK cohorts to stratify patients by acute seizure risk. A ‘basic score’ used Glasgow Coma Scale (GCS), fever and age; the ‘advanced score’ added aetiology. This study aimed to evaluate the score internationally to determine its global applicability.

Patients were retrospectively analysed regionally, and by country, in this international evaluation study. Univariate analysis was conducted between patients who did and did not have inpatient seizures, followed by multivariable logistic regression, hierarchical clustering and analysis of the area under the receiver operating curves (AUROC) with 95% CIs.

2032 patients across 13 countries were identified, among whom 1324 were included in SEIZURE score calculations and 970 were included in regression modelling. The involved countries comprised 19 organisations spanning all WHO regions.

The primary outcome was measuring inpatient seizure rates.

Autoantibody-associated encephalitis, low GCS and presenting with a seizure were frequently associated with inpatient seizures; fever showed no association. Globally, the score had limited discriminatory ability (basic AUROC 0.58 (95% CI 0.55 to 0.62), advanced AUROC 0.63 (95% CI 0.60 to 0.66)). The scoring system performed acceptably in western Europe, excluding Spain, with the best performance in Portugal (basic AUROC 0.82 (95% CI 0.69 to 0.94), advanced AUROC 0.83 (95% CI 0.72 to 0.95)).

The SEIZURE score performed best in several countries in Western Europe but performed poorly elsewhere, partly due to differing and unknown aetiologies. In most regions, the score did not reach a threshold to be clinically useful. The Western European results could aid in designing clinical trials assessing primary anti-seizure prophylaxis in encephalitis following further prospective trials. Beyond Western Europe, there is a need for tailored, localised scoring systems and future large-scale prospective studies with optimised aetiological testing to accurately identify high-risk patients.

Substance use among adolescent expectant mothers is a significant public health concern due to its adverse effects on both maternal and fetal health. Despite this, there is limited evidence regarding the patterns and factors influencing substance use among pregnant adolescents in Ghana.

This study aimed to explore the psycho-social and cultural factors that influence substance use among adolescent expectant mothers attending the antenatal clinic at the Upper East Regional Hospital in the Bolgatanga municipality.

A qualitative, descriptive exploratory design was employed. 17 adolescent expectant mothers were purposively recruited and interviewed using a researcher-developed semistructured guide. Interviews were audio-recorded, transcribed verbatim and analysed using a six-step thematic analysis guided by a deductive approach. The study was underpinned by the socioecological model, which allowed for the exploration of knowledge, social and cultural factors influencing substance use during pregnancy.

The study was conducted at the antenatal clinic of the Upper East Regional Hospital in Bolgatanga and involved adolescent expectant mothers attending the clinic.

Analysis revealed three major themes: knowledge of substance use, social factors and cultural factors influencing substance use. Participants demonstrated understanding of substance use, including its definition, causes and potential consequences. Social influences, particularly peer pressure and family dynamics, were reported as motivating factors for substance use. Cultural factors, including local beliefs, practices and community attitudes, also played a significant role in shaping substance use behaviours among these adolescents.

The findings indicate that while adolescent expectant mothers possess knowledge about the risks and consequences of substance use during pregnancy, many continue to engage in such behaviours. Peer and family influences, alongside cultural beliefs and community attitudes, were identified as key drivers of substance use. These results highlight the need for targeted, culturally sensitive substance use education and intervention programmes within antenatal clinics and the broader community to support adolescent mothers in reducing substance use during pregnancy.

This study aimed to determine the prevalence and antimicrobial susceptibility profile of non-fermenting Gram-negative bacilli (NFGNB) isolated from clinical samples in a tertiary care hospital in Niger.

Prospective, cross-sectional study.

The study was carried out in a tertiary care hospital in Niger.

All clinical samples received at the bacteriology laboratory during the study period for diagnostic purposes were included.

Out of 548 clinical Gram-negative isolates, 60 strains of NFGNB (10.94%) were isolated. These NFGNB strains were mainly isolated from male patients (62%, n=37) with a mean age of 41.2±27.3 years. NFGNB was more frequent in urine samples (91.7%), followed by pus (6.6%). Among the NFGNB strains isolated, Acinetobacter baumannii was predominant (60%), followed by Pseudomonas aeruginosa (18.3%) and Stenotrophomonas maltophilia (13.33%). 20% (n=12) of NFGNB isolated were multidrug-resistant (MDR), including 13.33% (n=8) carbapenem-resistant A. baumannii and 6.67% (n=4) carbapenem-resistant P. aeruginosa. There is no statistically significant association between MDR-NFGNB and age, sex and origin of patients (p>0.05).

Our study revealed a relatively high MDR-NFGNB prevalence rate in a Nigerien tertiary care hospital. These findings emphasise the need for vigilant antibiotic stewardship, with appropriate infection prevention and control practices to curb the emergence and spread of MDR-NFGNB infections in hospital settings.
