Predictors of Stunting and Pathway Analysis for Linear Growth among Children Aged Two to Three Years after a Trial of Small-Quantity Lipid-Based Nutrient Supplements and Home-Installed Growth Charts in Three Districts in Zambia.

Background: Globally, 148 million children aged <5 y are stunted, with risk factors varying by context. Our "Impact of Growth Charts and Nutritional Supplements on Child Growth in Zambia" (ZamCharts) trial observed persistently high rates of stunting in all treatment groups after 18-mo of intervention with monthly distributions of small-quantity lipid-based nutrient supplements (SQ-LNS) and/or installation of a wall-mounted growth chart in children's homes.

Objectives: We sought to identify determinants of stunting and height-for-age z-score in children aged 27-36 mo who participated in the ZamCharts endline survey (n = 1911).

Using a digital transformation framework to explore the experiences of radiographers in the use of digital radiography in a low-resource setting.

Introduction: Digital radiography (DR) systems have revolutionised radiographers' experiences, particularly those accustomed to analogue methods. Despite the advantages, DR poses challenges due to its cost and technical requirements, especially in low-resource settings. Zambia, predominantly reliant on analogue systems, is gradually transitioning to DR.

Did socioeconomic inequalities in overweight and obesity in South African women of childbearing age improve between 1998 and 2016? A decomposition analysis.

Overweight and obesity in adult women contribute to deaths and disability from non-communicable diseases (NCDs) and obesity-related health problems in their offspring. Globally, overweight and obesity prevalence among women of childbearing age (WCBA) has increased, but associated socioeconomic inequality remains unclear. This study, therefore, assesses the changing patterns in the socioeconomic inequality in overweight and obesity among South African non-pregnant WCBA between 1998 and 2016.

PhysioCAFUN: a competency-based curriculum development guideline to strengthen physiology education in Africa.

Physiology education in Africa faces challenges due to gaps in curricula across many of its universities, such as divergent content, a lack of standardized competencies, and suitable benchmarking. Here, we describe the development of the Physiology Curriculum for African Universities (PhysioCAFUN), a competency-based curriculum development guideline, as a first step to address such shortcomings. A committee of 15 physiologists from different African regions, Europe, and the United States was constituted to draft the PhysioCAFUN, which was introduced and revised during the joint East African Society of Physiological Sciences (EASPS) and African Association of Physiological Sciences (AAPS) conference held in Tanzania late 2023.

Imaging and Circulating Biomarker-Defined Cardiac Pathology in Pulmonary Tuberculosis: A Systematic Review.

Background: Pulmonary tuberculosis (PTB) is associated with increased cardiovascular disease (CVD) mortality. However, underlying pathophysiological mechanisms are poorly understood. This systematic review aims to synthesise the evidence on the prevalence of cardiac pathology based on cardiac imaging and circulating biomarkers in patients with PTB.

The economic, social, and environmental impact of ecologically centered integrated pest management practices in East Africa.

Agricultural pest management faces mounting challenges with increasing pressure to reduce chemical pesticide use while ensuring food security, and environmental sustainability. Ecologically centered approaches, such as integrated pest management (IPM), offer promising sustainable agroecological crop protection alternative solutions to pesticides. This study assesses the investment viability and environmental sustainability of two IPM interventions-mango fruit fly IPM (FF-IPM) and push-pull technology (PPT) in Kenya and Uganda, using project investment and adoption data from 2007 to 2021.

A Retrospective Analysis of Lessons Learned and Perspectives on Expansion of Verbal Autopsy Implementation in Zambia, 2023.

Accurate cause-of-death statistics are vital for public health policy, but less than one-third of deaths globally are assigned a cause. Verbal autopsy (VA) methods are crucial in low- and middle-income countries lacking complete civil registration and vital statistics (CRVS) systems. We explored VA implementation in Zambia by using a previously developed framework.

The Pan-African Surgical Healthcare Forum: An African qualitative consensus propagating continental national surgical healthcare policies and plans.

Access to equitable, safe, affordable, timely, and quality surgical healthcare in Africa remains limited. Few African countries have surgical healthcare plans or policies. Where these exist, there are significant gaps in dissemination, funding, and implementation.

Epithelial Na+ Channels, Immune Cells, and Salt.

Epithelial Na+ channels (ENaCs) are known to affect blood pressure through their role in transporting Na+ in the distal nephron of the kidney. While expressed in other epithelial tissues, there is growing evidence that ENaCs are also expressed in nonepithelial tissues where their activity influences blood pressure. This review provides an overview of ENaCs and key mechanisms that regulate channel activity.

Association between complete blood-count-based inflammatory scores and hypertension in persons living with and without HIV in Zambia.

Background: Hypertension is a risk factor for cardiovascular events. Inflammation plays an important role in the development of essential hypertension. Studies assessing the association between complete blood count-based inflammatory scores (CBCIS) and hypertension are scarce.

Associations of linear growth with body composition of perinatally HIV-infected African adolescents.

The prevalence of poor linear growth among African children with perinatally acquired HIV remains high. There is concern that poor linear growth may to lead to later total and central fat deposition and associated non-communicable disease risks. We investigated associations between height-for-age score (HAZ) and total and regional fat and lean mass measured by dual-energy X-ray absorptiometry, expressed as internal population scores, among 839 Zimbabwean and Zambian perinatally HIV-infected male and female adolescents aged 11-19 years.

ticks: new hosts for phleboviruses.

Ticks are widespread arthropods that transmit microorganisms of veterinary and medical significance to vertebrates, including humans. , an ixodid tick frequently infesting and feeding on humans, may play a crucial role in transmitting infectious agents across species. Despite the known association of many ticks with phleboviruses, information on is lacking.

Routine HPV vaccination: Reflection on delivery strategies based on countries' experiences.

Despite the introduction of the human papillomavirus (HPV) vaccine in many low- and middle-income countries (LMICs), countries are still struggling to maintain HPV vaccination coverage and manage sustainable delivery strategies. This article explores the challenges and effective strategies for HPV vaccine delivery in LMICs, with a focus on reflecting upon current HPV vaccine delivery strategies in the World Health Organization (WHO) HPV vaccine introduction guidelines to align with practical implementation experiences. The article utilizes presentations and discussions from Coalition to Strengthen the HPV Immunization Community (CHIC) symposia, field experiences of program implementers who participated in the meeting and immunization expert opinions, to inform its findings.

Pandemic-related resilience in HPV vaccination programmes - Perspectives from selected countries in Africa on what it will take to vaccinate 90 % of girls by 2030.

The COVID-19 pandemic resulted in widespread disruptions to primary health care and other sectors, halting the majority of routine immunisation services and particularly impacting newer, less routinized HPV vaccine programmes. We present a series of five country case studies, drawing directly from frontline experiences in Côte d'Ivoire, Kenya, Liberia, Zambia, and Senegal to explore potential barriers and enablers of national HPV vaccine programme resiliency in the aftermath of a pandemic. A series of common themes emerged, articulating common challenges to maintaining HPV vaccine programmes, common factors that supported programme resilience, and common themes of resource needs to rebuild stronger routine immunisation programmes to face future threats.

Acceptability, barriers and facilitators of using dried blood spots-point-of-care testing for sickle cell disease in Africa: an implementation science protocol for a multinational qualitative study.

Background: Sickle cell disease (SCD) is a prevalent inherited blood disorder. Globally, approximately 515 000 babies are born with SCD annually, with 75% of these births occurring in Africa. Integrating newborn screening (NBS) for SCD into primary healthcare structures, such as immunisation programmes, holds significant promise, with dried blood spots (DBS)-point-of-care technologies (POCT) like HaemoTypeSC offering cost-effective screening solutions.

Feasibility and acceptability of the Problem Management for Moms programme for improving maternal mental health in Zambia: an open-label trial.

Background: Psychological distress is common among mothers in low-income and middle-income countries, limiting their capacity to care for themselves and their children. This study aimed to test the feasibility and acceptability of an adapted psychosocial intervention for distressed mothers in low-resource settings.

Methods: In this open-label trial, we enrolled women living in Lusaka, Zambia, with high mental distress (>7 score on the 20-item Self-Reporting Questionnaire [SRQ-20]) and children younger than 2 years, who had previously enrolled in the ZamCharts early childhood nutrition trial.

Uptake and perceptions of voluntary medical male circumcision among HIV-negative men in serodiscordant relationships in Zambia (2012-2015).

Voluntary medical male circumcision (VMMC) is a recommended HIV prevention strategy that few studies have promoted to HIV-negative men in serodiscordant relationships. We conducted a cross-sectional study on uptake and perceptions of VMMC among serodiscordant couples between 2012 and 2015. Heterosexual couples attending couples voluntary counselling and testing for HIV who had discordant results (M-, F+) were referred for VMMC.

An exploratory cross-cultural study of community-based health literacy interventions to promote the mental well-being of disadvantaged and disabled young Africans: a multi-method approach.

Background: This study explores the impact of community-based health literacy interventions on the health and mental well-being of disadvantaged young Africans in Zambia, Sierra Leone, Rwanda, and South Africa. The pandemic has exacerbated mental health problems amongst children and young people, underscoring the urgent need for equitable access to mental healthcare resources. Emphasizing the importance of equitable access to mental healthcare resources, the research addresses educational and income disparities in low- and middle-income countries (LMICs), particularly amongst young Africans with disabilities or vulnerabilities.

Snakebite envenoming in Africa remains widely neglected and demands multidisciplinary attention.

Snakebite envenoming can cause morbidity, permanent disability or death but treatment and prevention thereof remains highly inadequate in Africa. Overcoming structural and financial barriers that impede existing initiatives to improve medical management and mitigate human-snake conflict is urgently needed.
