The study involved stakeholders (parents/guardians, teachers, principals, proprietors/owners and administrators) and data was collected using a validated questionnaire.

Phenotypic characterization of NK cells in 5-year-old children exposed to maternal HIV and antiretroviral therapy in early-life.

Background: HIV-exposed uninfected (HEU) children are at increased risk of morbidity during the first years of life. Although the immune responses of HEU infants in early-life are relatively well described, studies of natural killer (NK) cells in older HEU children are lacking. NK cell subsets were analysed in HEU children and compared to those in HIV unexposed uninfected (HUU) children aged ~ five years.

Methods for measuring body composition in Zambian adolescents living with HIV.

Assessment of body composition can be useful in managing many clinical or public health conditions, including HIV. Most people living with HIV infection are in Africa where clinics may lack equipment, utilities or staff time for optimal body composition assessment. Thus, it is important to determine whether less expensive and more available and scalable methods can provide adequate information.

It examined the current state of food and nutrition security, fish production, and fish consumption patterns. Additionally, the study investigated the challenges and opportunities to enhance fish production in these countries thereby enhancing food and nutrition security.

Validation of prognostic models predicting mortality or ICU admission in patients with COVID-19 in low- and middle-income countries: a global individual participant data meta-analysis.

Background: We evaluated the performance of prognostic models for predicting mortality or ICU admission in hospitalized patients with COVID-19 in the World Health Organization (WHO) Global Clinical Platform, a repository of individual-level clinical data of patients hospitalized with COVID-19, including in low- and middle-income countries (LMICs).

Methods: We identified eligible multivariable prognostic models for predicting overall mortality and ICU admission during hospital stay in patients with confirmed or suspected COVID-19 from a living review of COVID-19 prediction models. These models were evaluated using data contributed to the WHO Global Clinical Platform for COVID-19 from nine LMICs (Burkina Faso, Cameroon, Democratic Republic of Congo, Guinea, India, Niger, Nigeria, Zambia, and Zimbabwe).

A survey of magnetic resonance imaging (MRI) availability and cost in Zimbabwe: Implications and strategies for improvement.

Introduction: Resolution 60.29 (18) of the 60th United Nations World Health Assembly urges member states to gather, verify, update, and exchange information on health technologies, especially medical devices. This study assesses Zimbabwe's MRI service availability and cost, identifies disparities, and discusses implications for patient care and healthcare equity, proposing evidence-based improvement strategies.

The economic value of seasonal weather and climate services for maize farmers in Manicaland Province of Zimbabwe.

Most rural areas in Zimbabwe are extremely vulnerable to changing climatic conditions, particularly droughts, which threaten smallholder farmers' livelihoods. Seasonal weather forecast services can help farmers adapt, optimise production, and implement risk reduction strategies. To support increased investment in these services, this study seeks to provide quantitative evidence on the economic value of locality-specific seasonal weather forecasts by eliciting maize producers' willingness to pay (WTP) through the contingent valuation approach.

Innovative clearance data model for demining operational data collection: Insights from field trials in Zimbabwe.

From September 2023 to March 2024 a field trial on a live manual demining site was conducted to test a new and innovative approach for the collection and analysis of operational data. The approach, titled the Clearance Data Model, involved the collection of sixty-six data attributes for each mine found. For the first time the mine itself would become the accountable unit of demining data, against which an expanded range of relevant attributes particular to that specific mine would be recorded.

Recommendations for the optimal introduction of novel antibiotics to treat uncomplicated gonorrhoea in the face of increasing antimicrobial resistance: a case study with zoliflodacin.

New, first-in-class oral antibiotics like zoliflodacin, developed in a public-private partnership, require an optimal introduction strategy while ensuring antibiotic stewardship. Zoliflodacin, given as a single dose for uncomplicated urogenital gonorrhoea, recently demonstrated non-inferiority to ceftriaxone plus azithromycin and safety in a phase 3 randomised controlled trial. Following regulatory approval, zoliflodacin could improve sexually transmitted infection (STI) management and help address the threat of untreatable gonorrhoea, as levels of resistance to current first-line treatments increase.

Strengthening health financing at sub-national level in Kenya: a stakeholder and needs mapping through a mixed methods approach.

Introduction: health financing aims to ensure that the overall goal of the health system is attained. Countries with decentralised healthcare systems such as Kenya, face further challenges due to limited public financial management capacity within sub-national governments. While partner support has proved impactful in addressing these challenges, there is a paucity of evidence on the nature and distribution of the support in Kenya.

Development and Application of a Quantitative Model for Proximate and Ultimate Analysis of Flue-Cured Tobacco Based on Near-Infrared Spectroscopy.

A methodology for predicting proximate and ultimate analysis data was developed by using near-infrared spectroscopy (NIR) combined with chemometric methods. The quantitative model has high accuracy, as evidenced by low root-mean-square-error of prediction (RMSEP) values (e.g.

Assessing the potential impact of livestock immunisation and acaricide use on controlling the spread of East Coast fever.

Immunisation of livestock with high-quality vaccines and the use of acaricides are highly ranked tick control strategies worldwide. However, the effects of coupling livestock immunisation and acaricide control on mitigating the spread of East Coast Fever (ECF) is not well understood. Effective strategies to curb the disease require an understanding of the influence of control strategies on ECF dynamics.

Aims: Determine prevalence of trauma exposure, prevalence of probable PTSD and conditional prevalence of probable PTSD for different traumatic events; and better understand the experiences of individuals with HIV and PTSD.

Method: This mixed method study used secondary data from a cross-sectional survey of people ( = 222) aged 18 to 29 living with HIV in Zimbabwe and primary qualitative data collection.

Therapeutic interventions targeting enteropathy in severe acute malnutrition modulate systemic and vascular inflammation and epithelial regeneration.

Background: Severe acute malnutrition (SAM) is the most life-threatening form of undernutrition, and children hospitalised with complications have unacceptably high mortality. Complicated SAM is a multisystem disease characterised pathophysiologically by muscle wasting, systemic inflammation, metabolic dysfunction, and malnutrition enteropathy including epithelial barrier dysfunction. There is a clear need for novel interventions to address the underlying pathogenic perturbations of complicated SAM.
