Expediting pathogen genomics adoption for enhanced foodborne disease surveillance in Africa.

The role of genomics in public health surveillance has been accentuated by its crucial contributions during the COVID-19 pandemic, demonstrating its potential in addressing global disease outbreaks. While Africa has made strides in expanding multi-pathogen genomic surveillance, the integration into foodborne disease (FBD) surveillance remains nascent. Here we highlight the critical components to strengthen and scale-up the integration of whole genome sequencing (WGS) in foodborne disease surveillance across the continent.

Factors Associated with Favorable Tuberculosis Treatment Outcomes Determined Using Multiple Regression Analysis in Lusaka, Zambia, 2022.

Background: This study aims to identify the factors associated with favorable treatment outcomes of tuberculosis (TB) patients registered at two hospitals and two urban health centers in Lusaka, Zambia in 2022.

Lessons from an intervention study on the sustainability of after-school comprehensive sexuality education in Zambia: the perspectives of teachers, health workers and guardians.

Background: Comprehensive sexuality education (CSE) has been introduced in many sub-Saharan African countries, but limited political interest and insufficient funding have resulted in many CSE initiatives being dependent on donor funding or non-governmental organisations (NGOs) supporting its implementation. This has created concerns about the sustainability of the programmes. The objective of this study was to explore factors affecting the sustainability of CSE delivered through a youth club organized after school hours in Zambia.

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).

The spatial distribution of intimate partner violence prevalence and its associated factors among women aged 15-49 years in Zambia: evidence from the 2018 Demographic and Health Survey.

Background: Intimate partner violence (IPV) includes any physical, sexual, or emotional harm experienced in any intimate relationship that results in negative outcomes. Zambia is one of the countries with the highest prevalence of IPV amongst women in sub-Saharan Africa. This study aims to investigate and describe the prevalence, associated risk factors, and geo-spatial distribution of IPV amongst women aged 15-49 years from the 2018 Zambia Demographic and Health Survey (ZDHS).

Early user perspectives on using computer-aided detection software for interpreting chest X-ray images to enhance access and quality of care for persons with tuberculosis.

Despite 30 years as a public health emergency, tuberculosis (TB) remains one of the world's deadliest diseases. Most deaths are among persons with TB who are not reached with diagnosis and treatment. Thus, timely screening and accurate detection of TB, particularly using sensitive tools such as chest radiography, is crucial for reducing the global burden of this disease.

Community-based active-case finding for tuberculosis: navigating a complex minefield.

Community-based active case finding (ACF) for tuberculosis (TB) involves an offer of screening to populations at risk of TB, oftentimes with additional health promotion, community engagement and health service strengthening. Recently updated World Health Organization TB screening guidelines conditionally recommend expanded offer of ACF for communities where the prevalence of undiagnosed pulmonary TB is greater than 0.5% among adults, or with other structural risk factors for TB.

Advancing laparoscopic skills training in Namibia: Implementation of the Global Laparoscopic Advancement Program (GLAP) of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES).

Background: In low- and middle-income countries (LMICs), laparoscopic surgery is challenging to implement due to limited resources and lack of expert surgeons as teachers. The Global Laparoscopic Advancement Program (GLAP) was developed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to deliver sustainable and effective methods for teaching safe laparoscopic surgery. GLAP aims to train surgical leaders and trainees with the goal of eventual in-country replication of GLAP programming.

Empowerment and utilization of HIV testing among partnered women in Zambia: Evidence from the Zambia demographic and health survey 2018.

In Zambia, women are disproportionally more affected by HIV compared to men. This has mainly been attributed to harmful gender norms that enhance male dominance and disempower women, preventing them from exercising their right to negotiate for safe sex and utilizing HIV prevention services such as HIV testing. This study examined associations between empowerment and HIV testing among married and partnered women.

Ecology meets reproductive medicine in HIV prevention: the case for geography-informed approaches for bacterial vaginosis in Africa.

Purpose Of Review: Women in Africa bear the burden of the HIV epidemic, which has been associated with the high prevalence of bacterial vaginosis (BV) in the region. However, little progress has been made in finding an effective cure for BV. Drawing on advances in microbiome-directed therapies for gastrointestinal disorders, similar live-biotherapeutic based approaches for BV treatment are being evaluated.

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.
