Global new-born mortality has shown steady decline over the last two decades, but this decline has been slowest in Sub-Saharan Africa (SSA). Perinatal asphyxia (PA) is a major cause of new-born deaths in this region and as such SSA now contributes a disproportionate large percentage of global asphyxia-related deaths. In this paper, we examine regional challenges affecting primary, secondary and tertiary prevention of PA and proffers locally adaptable solutions to these identified challenges.

Background: Birth asphyxia accounts for a third of global newborn deaths and 95 percent of these occur in low-resource settings. A key to reducing asphyxia-related deaths in these settings is improving care of these newborns and this requires an understanding of factors associated with adverse outcomes. Objectives: In this study, we report outcomes and risk factors for mortality among newborn infants with birth asphyxia admitted to a typical low-resource hospital setting. Methods: We prospectively followed up 191 asphyxiated newborn infants admitted to a referral tertiary hospital in North-central Nigeria. At baseline, care-givers completed a structured questionnaire. Using univariable analysis, we compared baseline characteristics between participants who died and those who survived till discharge. We also fitted a multivariable logistic regression model to identify risk factors for mortality among the cohort. Results: Majority (60.7%) of the study participants presented to the hospital within the first six hours of life. Despite this, mortality among the cohort was 14.7% with a third dying within the first 24 hours of admission. The presence of respiratory distress at admission increased the risk for mortality (AOR = 3.73, 95% CI 1.22 to 11.35) while higher participant weight at admission decreased the risk (AOR = 0.11, 95% CI 0.03 to 0.40). Intrapartum factors such as duration of labour and maternal age, although significant on univariable analysis, were not significant on multivariable analysis. Conclusions: Hospital mortality among newborns with birth asphyxia is high in North-central Nigeria and majority of deaths occur during acute care. Respiratory distress at presentation and admission weights were identified as key risk factors for asphyxia mortality. Intrapartum factors on the other hand might have indirect effects on mortality through an increased risk for neonatal complications.

Background Stunting and severe wasting can co-occur in under-fives, predisposing them to increased risks for morbidity and mortality. The Community Management of Acute Malnutrition (CMAM) programme, which provides outpatient malnutrition care for severely wasted children, has been successful at managing severe wasting, but there are limited data on stunting among entrants into these programmes. Methods We performed secondary analysis of data collected from attendees of two CMAM centres in north-western Nigeria. Using WHO reference standards, we determined the prevalence of concurrent stunting (height/length-for-age <-2 SD) among severely wasted children (weight-for-height z-scores <-3 SD). We identified individual and household-level risk factors for concurrent stunting using multivariable logistic regression analysis. Results Our cohort comprised 472 severely wasted children and the majority (82.8%) were stunted. Age groups of 12–23 mo (adjusted OR [AOR]=2.38, 95% CI 1.26 to 4.48) and 24–35 mo (AOR=7.81, 95% CI 1.99 to 30.67), male gender (AOR=2.51, 95% CI 1.43 to 4.39) and attending the rural malnutrition clinic (AOR=3.08, 95% CI 1.64 to 5.79) were associated with a significantly increased probability of stunting. Conclusions Stunting prevalence is high among severely wasted children attending CMAM programmes in north-western Nigeria. Policymakers need to adapt these treatment programmes to also cater for stunting, taking into account practical programmatic realities such as available expertise and scarce resource allocation.

Background: Infection contributes to significant morbidity and mortality particularly in the very young and in low-and middle-income countries. While vaccines are a highly cost-effective tool against infectious disease little is known regarding the cellular and molecular pathways by which vaccines induce protection at an early age. Immunity is distinct in early life and greater precision is required in our understanding of mechanisms of early life protection to inform development of new pediatric vaccines.Methods and Analysis: We will apply transcriptomic, proteomic, metabolomic, multiplex cytokine/chemokine, adenosine deaminase, and flow cytometry immune cell phenotyping to delineate early cellular and molecular signatures that correspond to vaccine immunogenicity. This approach will be applied to a neonatal cohort in The Gambia (N ∼ 720) receiving at birth: (1) Hepatitis B (HepB) vaccine alone, (2) Bacille Calmette Guerin (BCG) vaccine alone, or (3) HepB and BCG vaccines, (4) HepB and

Background Children with uncomplicated severe acute malnutrition are managed routinely within out-patient malnutrition treatment programs. These programs do not offer maternal mental health support services, despite maternal mental health playing a significant role in the nutritional status of children. Additionally, the burden of maternal Common Mental Disorders (CMDs) is poorly described among mothers of children attending these programs. This study thus determined the burden and risk factors for maternal CMDs among children attending out-patient malnutrition clinics in rural North-western Nigeria. Methods We conducted a cross-sectional study among 204 mothers of children with severe acute malnutrition who attending eight out-patient malnutrition clinics in Jigawa, North-western Nigeria. We used the World Health Organization Self-Reporting Questionnaire-20 (WHO SRQ-20) screening tool, a recognised and validated proxy measure for CMDs to identify mothers with CMDs. The prevalence of maternal CMDs was determined by identifying the proportion of mothers with SRQ scores of ≥8. Risk factors for CMD were determined using multivariable logistic regression. Results Maternal CMD prevalence in children attending these facilities was high at 40.7%. Non-receipt of oral polio vaccine (OPV) (AOR 6.23, 95%CI 1.85 to 20.92) increased the odds for CMD. While spousal age above 40 (AOR 0.95, 95%CI 0.90 to 0.99) and long years spent married (AOR 0.92, 95%CI 0.85 to 0.98) decreased the odds for CMD. Conclusions Our findings indicate maternal CMD burden is high in out-patient malnutrition clinics in North-western Nigeria. Maternal mental health services would need to be integrated into the community management of acute malnutrition programs to provide more holistic care, and possibly improve long-term outcomes after discharge from these programs.

Clinical research conducted to Good Clinical Practice (GCP) standards is increasingly being undertaken in resource-constrained low-income and middle-income countries (LMICs) settings. This presents unique challenges that differ from those faced in high-income country (HIC) contexts, due to a dearth of infrastructure and unique socio-cultural contexts. Field experiences by research teams working in these LMIC contexts are thus critical to advancing knowledge on successful research conduct in these settings. The Medical Research Council Unit The Gambia at London School of Hygiene and Tropical Medicine has operated in The Gambia, a resource-constrained LMIC for over 70 years and has developed numerous research support platforms and systems. The unit was the lead clinical collaborator in a recently completed Expanded Program on Immunization Consortium (EPIC) study, involving a multicountry collaboration across five countries including the USA, Canada, Belgium, Papua New Guinea and The Gambia. The EPIC study recruited and completed follow-up of 720 newborn infants over 2 years. In this paper, we provide in-depth field experience covering challenges faced by the Gambian EPIC team in the conduct of this study. We also detail some reflections on these challenges. Our findings are relevant to the international research community as they highlight practical day-to-day challenges in conducting GCP standard clinical research in resource-constrained LMIC contexts. They also provide insights on how study processes can be adapted early during research planning to mitigate challenges.

Background Severe acute malnutrition (SAM) is associated with significant morbidity and mortality and is disproportionately distributed mainly in developing countries. In Nigeria, the prevalence of SAM in the North-Western region of the country is significantly higher than the national average. In this study, we identified risk factors for SAM in North-Western Nigeria. Identifying such risk factors would be helpful in developing local preventive strategies and providing insights for broader SAM control programs in other high-burden country settings. Methods We performed post hoc data analysis, comparing baseline socio-demographic and household-level risk factors in a cohort of 1011 children aged between 6 and 59 months who either had SAM or were well-nourished children. We defined nutritional status using the World Health Organization (WHO) reference standards and investigated the association between SAM and our identified risk factors using multivariable logistic regression model. Results Children aged between 12 and 23 months [adjusted odds ratio (AOR) 2.95, 95% confidence interval (CI) 1.99–4.38], household who reared domestic animals (AOR 1.94, 95% CI 1.40–2.69) and those from polygamous households (AOR 1.91, 95% CI 1.33–2.74) had significantly increased odds of developing SAM. Parental education and being on the household diet reduced the odds of having SAM. Conclusions Our findings suggest the need to develop optimal complementary feeding nutrition programs and promote adult and general education in our community. Cultural and feeding practices in local polygamous households also need further investigation to understand the association between polygamy with SAM.

Background: Adequate staffing is key to the delivery of nursing care and thus to improved inpatient and health service outcomes. Several systematic reviews have addressed the relationship between nurse staffing and these outcomes. Most primary studies within each systematic review are likely to be from high-income countries which have different practice contexts to low and middle-income countries (LMICs), although this has not been formally examined. We propose conducting an umbrella review to characterise the existing evidence linking nurse staffing to key outcomes and explicitly aim to identify evidence gaps in nurse staffing research in LMICs. Methods and analysis: This protocol was developed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P). Literature searching will be conducted across Ovid Medline, Embase and EBSCO Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Two independent reviewers will conduct searching and data abstraction and discordance will be handled by discussion between both parties. The risk of bias of the individual studies will be performed using the AMSTAR-2. Ethics and dissemination: Ethical permission is not required for this review as we will make use of already published data. We aim to publish the findings of our review in peer-reviewed journals.
