Association between ultra-processed food consumption, sociodemographic characteristics, malnutrition and obesity among urban school-aged children in Lilongwe, Malawi: a cross-sectional study.

Introduction: The escalating consumption of ultra-processed foods (UPFs) among school-aged children in developing countries poses a significant threat to public health, contributing to the dual burden of malnutrition. In Malawi, where undernutrition coexists with a burgeoning obesity epidemic, understanding the determinants of UPF consumption and its impact on children's nutritional status is imperative. This study, conducted in Lilongwe, Malawi, aimed to investigate the association between UPF consumption, sociodemographic factors and the nutritional status of school-aged children.

Factors associated with under-five mortality in Rwanda: An analysis of the Rwanda Demographic and Health Survey 2020.

Despite global and Rwandan progress in reducing under-five mortality, the risk of children dying before their fifth birthday persists, necessitating intensified research on determinants. Thus, this study analyzed the birth history data to shed light on the underlying causes of under-five mortality in Rwanda. The study is a secondary analysis of data sourced from the 2020 Rwanda Demographic and Health Survey (RDHS) cross-sectional design.

Serological surveillance of GI norovirus reveals persistence of blockade antibody in a Jidong community-based prospective cohort, 2014-2018.

Introduction: Herd immunity against norovirus (NoV) is poorly understood in terms of its serological properties and vaccine designs. The precise neutralizing serological features of genotype I (GI) NoV have not been studied.

Methods: To expand insights on vaccine design and herd immunity of NoVs, seroprevalence and seroincidence of NoV genotypes GI.

Development and evaluation of a new luciferase immunosorbent assay to detect GII.6 norovirus-specific IgG in different domestic and wild animals.

Noroviruses (NoVs) are the leading viral pathogens globally causing acute gastroenteritis (AGE) in humans, posing a significant global health threat and economic burden. Recent investigations revealed that human NoVs had been detected in different animals, which raises concerns about whether NoVs are potential zoonotic diseases. This study developed a novel luciferase immunosorbent assay (LISA) to detect GII.

Under-five mortality in Sierra Leone and possible associated factors: evidence from the 2019 Demographic and Health Survey.

High under-five mortality rate remains one of the public health challenges, especially in Sub-Saharan Africa, accounting for more than half of all global cases. Sierra Leone was and is still one of the countries with the highest under-five mortality rate. Using the latest 2019 Sierra Leone Demographic and Health Survey data, we investigated factors associated with under-five mortality in Sierra Leone.

Serological surveillance of noroviruses in a community-based prospective cohort: a study protocol.

Introduction: Noroviruses are the leading cause of viral acute gastroenteritis affecting all age groups. Since 2014, the previous rarely reported GII.P17-GII.

Pilot drug and therapeutic committee programme in Sierra Leone: A descriptive mixed method study.

Aims: Irrational medicine use is a global crisis, but incidences are proportionately higher in low- and middle-income countries such as Sierra Leone. This study explores the structure, functions and challenges of drug and therapeutics committees (DTCs), an intervention towards irrational medicine use recently piloted in Sierra Leone.

Methods: A 2-phase mixed-method study design was used in this study.
