Prevalence and factors associated with moderate-to-severe anaemia among virally suppressed people with HIV at a tertiary hospital in Zambia.

Objective: Anaemia is associated with an increased risk of disease progression and all-cause mortality among HIV-infected individuals, regardless of the type of anaemia, but the magnitude of the risk is greater with more severe forms of anaemia. Although anaemia PLWH has been extensively studied, the focus has primarily been on its prevalence and association with disease progression in untreated or poorly controlled HIV cases. This study aimed to investigate the prevalence, and factors associated with moderate-to-severe anaemia among virally suppressed HIV patients at a tertiary hospital in Zambia.

Severe acute malnutrition among children under the age of 5 years.

Background: Severe acute malnutrition (SAM) poses a significant threat to child health globally, particularly in low- and middle-income countries. Zambia, like many Sub-Saharan African nations, faces high rates of child malnutrition, with SAM contributing significantly to under-five mortality. Therefore, this study aimed to determine the prevalence and factors associated with SAM.

BaTwa populations from Zambia retain ancestry of past hunter-gatherer groups.

Sub-equatorial Africa is today inhabited predominantly by Bantu-speaking groups of Western African descent who brought agriculture to the Luangwa valley in eastern Zambia ~2000 years ago. Before their arrival the area was inhabited by hunter-gatherers, who in many cases were subsequently replaced, displaced or assimilated. In Zambia, we know little about the genetic affinities of these hunter-gatherers.

Halting and re-issuing of the Zambia community health strategy (2017-2021): a retrospective analysis of the policy process and implications for community health systems.

Background: Over the years, low-and middle-income countries have adopted several policy initiatives to strengthen community health systems as means to attain Universal Health Coverage (UHC). In this regard, Zambia passed a Community Health Strategy in 2017 that was later halted in 2019. This paper explores the processes that led to the halting and re-issuing of this strategy with the view of drawing lessons to inform the development of such strategies in Zambia and other similar settings.

Influence of HIV status on outcomes of children admitted with sepsis at a paediatric hospital in Zambia: protocol for a prospective longitudinal study.

Introduction: Sepsis, a condition of global public health concern, is a major cause of morbidity and mortality, especially in patients with underlying HIV infection. This study aims to determine outcomes, aetiology and antibiotic resistance patterns among children with HIV exposure or infection admitted with a clinical presentation suggestive of sepsis who have confirmed bloodstream infections at Arthur Davison Children's Hospital (ADCH) in Ndola, Zambia.

Methods And Analysis: This will be a prospective longitudinal study of 200 children aged <2 years admitted with sepsis at ADCH with two of the following conditions: temperature of 38.

The first BILGENSA Research Network workshop in Zambia: identifying research priorities, challenges and needs in genital bilharzia in Southern Africa.

Female genital schistosomiasis (FGS) and male genital schistosomiasis (MGS) are gender-specific manifestations of urogenital schistosomiasis. Morbidity is a consequence of prolonged inflammation in the human genital tract caused by the entrapped eggs of the waterborne parasite, Both diseases affect the sexual and reproductive health (SRH) of millions of people globally, especially in sub-Sahara Africa (SSA). Awareness and knowledge of these diseases is largely absent among affected communities and healthcare workers in endemic countries.

Use what you have: leveraging microbiology support to develop a cumulative antibiotic susceptibility report for antimicrobial stewardship at a district hospital in Ghana.

Background: Antibiograms provide effective support for empirical prescribing and antimicrobial stewardship programmes (ASPs). In low-resource settings, microbiology systems to develop antibiograms may be rudimentary or entirely lacking, which may place such facilities at a disadvantage. Notwithstanding this, facilities should use what they have to support ASPs to inform evidence-based antibiotic use.

Carbon-based materials, metal composites, and polymer nanocomposites are explored for the anode, offering high energy density and capacity.

The prevalence of headache disorders in children and adolescents in Benin: a schools-based study.

Background: A global schools-based programme within the Global Campaign against Headache is estimating the burden of headache in children (6-11 years) and adolescents (12-17 years), cluster-sampling the world by conducting national studies in all world regions. Its purpose is to complement population-based studies in adults, adding to knowledge of the burden of headache and informing educational and health policies. This study in Benin was the third in the programme from sub-Saharan Africa (SSA).

Factors Associated with Outcomes at 1 Year in Paediatric Post-nephrectomy Patients for Nephroblastoma at the University Teaching Hospital and Cancer Diseases Hospital in Lusaka, Zambia.

Background: Nephroblastoma is the most common primary malignant renal tumour of childhood. The survival rates in high-income countries are approximately 90%. However, low-income countries have low survival rates of 20%-50%.

The Use of Narco SS Score in Predicting Adverse Events in Children Undergoing Major Elective Abdominal Surgery at The University Teaching Hospital, Lusaka, Zambia.

Background: The neurological, airway, respiratory, cardiovascular and other, with a subscore of surgical severity (NARCO-SS) is a scoring system which assesses the presence of systemic disease and the risk the operation poses to the patient. A number of patients that undergo major abdominal surgery suffer adverse events. The aim of the study was to determine the reliability of NARCO-SS in predicting peri-operative adverse events and to determine the risk factors for peri-operative adverse events in paediatric patients undergoing elective abdominal surgery.

Collaboration for implementation of decentralisation policy of multi drug-resistant tuberculosis services in Zambia.

Background: Multi-drug-resistant tuberculosis (MDR-TB) infections are a public health concern. Since 2017, the Ministry of Health (MoH) in Zambia, in collaboration with its partners, has been implementing decentralised MDR-TB services to address the limited community access to treatment. This study sought to explore the role of collaboration in the implementation of decentralised multi drug-resistant tuberculosis services in Zambia.

Coverage from medical teams and injury/illness epidemiology within youth athletics in Africa: A prospective study during the 2023 African Youth Under 18/20 Athletics Championships.

Objectives: To describe athletes' coverage by national medical teams, and injuries and illnesses occurring during the four weeks before and during the 2023 African Youth Under 18/20 Athletics Championships.

Design: Cross-sectional and prospective cohort study design.

The impact of home-installed growth charts and small-quantity lipid-based nutrient supplements (SQ-LNS) on child growth in Zambia: a four-arm parallel open-label cluster randomised controlled trial.

Background: Childhood stunting remains common in many low-income settings and is associated with increased morbidity and mortality, as well as impaired child development.

Methods: The main objective of the study was to assess whether home-installed growth charts as well as small-quantity lipid-based nutrient supplements (SQ-LNS) can reduce growth faltering among infants. All caregivers of infants between 2 and 10 months of age at baseline, and at least 6 months old at the beginning of the interventions, in 282 randomly selected enumeration areas in Choma, Mansa and Lusaka districts in Zambia were invited to participate in the study.

Seed color patterns in domesticated common bean are regulated by MYB-bHLH-WD40 transcription factors and temperature.

Seed colors and color patterns are critical for the survival of wild plants and the consumer appeal of crops. In common bean, a major global staple, these patterns are also essential in determining market classes, yet the genetic and environmental control of many pigmentation patterns remains unresolved. In this study, we genetically mapped variation for several important seed pattern loci, including T, Bip, p, and Z, which co-segregated with candidate genes PvTTG1, PvMYC1, PvTT8, and PvTT2, respectively.

Phylogeography and reassortment patterns of human influenza A viruses in sub-Saharan Africa.

The role of sub-Saharan Africa in the global spread of influenza viruses remains unclear due to insufficient spatiotemporal sequence data. Here, we analyzed 222 codon-complete sequences of influenza A viruses (IAVs) sampled between 2011 and 2013 from five countries across sub-Saharan Africa (Kenya, Zambia, Mali, Gambia, and South Africa); these genomes were compared with 1209 contemporaneous global genomes using phylogeographical approaches. The spread of influenza in sub-Saharan Africa was characterized by (i) multiple introductions of IAVs into the region over consecutive influenza seasons, with viral importations originating from multiple global geographical regions, some of which persisted in circulation as intra-subtype reassortants for multiple seasons, (ii) virus transfer between sub-Saharan African countries, and (iii) virus export from sub-Saharan Africa to other geographical regions.
