Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

The article explores the underlying factors influencing unhealthy diets and sedentary lifestyles among adolescents in Kilifi County, Kenya. Using a qualitative approach, the study involved interviews and focus group discussions with adolescents, stakeholders, and young adults. Key findings include a... preference for unhealthy, carbohydrate-rich, and sugary foods over traditional and nutritious options, exacerbated by factors like low socioeconomic status, urbanization, and poor farming practices.
Sedentary behavior, such as gambling and extensive technology use, was prevalent, often replacing physical activity. Protective factors like school attendance, community-based services, and parental engagement were identified as mitigating risks. The study highlights the importance of ecological intervention strategies targeting intrapersonal, interpersonal, and community factors to address unhealthy behaviors and promote better health outcomes in adolescents.

The document addresses the pressing issues of global malnutrition and the urgent need to build workforce capacity in public health nutrition, particularly in low- and middle-income countries. It highlights the dual burden of malnutrition, characterized by the coexistence of undernutrition and overnu...trition. While maternal and child undernutrition remain critical concerns, there is a growing prevalence of chronic diseases linked to overnutrition, even in resource-limited settings.
A significant gap exists in the availability of trained nutrition professionals. Many countries lack sufficient numbers of nutritionists, particularly at the undergraduate level, and existing training programs often focus on curative rather than preventive approaches. This leaves health workers inadequately prepared to address complex public health nutrition challenges.
To address these issues, the document recommends increasing the number of trained nutritionists, incorporating updated nutrition training into medical and nursing curricula, and developing competency frameworks and hybrid training programs. Accreditation systems for nutrition professionals are also proposed to ensure standardized and effective training.
Sustainability remains a challenge, with the need for long-term financing and better integration of nutrition programs into health systems. The document calls for systemic approaches to strengthen workforce capacity, enabling countries to effectively tackle the underlying causes of malnutrition.

The article from the African Journal of Thoracic and Critical Care Medicine provides updated guidelines on endoscopic lung volume reduction (ELVR) for treating advanced emphysema, a severe form of chronic obstructive pulmonary disease (COPD), which is prevalent in South Africa and other low- and mid...dle-income countries. The guidelines focus on identifying suitable patients based on specific criteria, such as age, lung function, and the presence of hyperinflation, while ruling out contraindications like pulmonary hypertension and recent smoking.
ELVR aims to reduce lung volume in the most damaged areas, improving breathing mechanics and quality of life. Various devices, including endobronchial valves, intrabronchial valves, and coils, are reviewed with evidence from clinical trials supporting their use. The guidelines emphasize careful patient selection and recommend only performing ELVR in specialized centers due to its high cost and risk of complications, such as pneumothorax.

The article "Can we prevent cardiovascular diseases in low- and middle-income countries?" by Claude Lenfant discusses the growing threat of cardiovascular diseases (CVDs) in developing countries. It highlights that while CVD is already the leading cause of death globally, low- and middle-income coun...tries are now facing rising CVD rates due to lifestyle changes associated with urbanization and economic growth. Lenfant advocates for a dual approach: identifying and treating high-risk individuals and promoting broad, population-wide prevention efforts focused on lifestyle changes such as reducing smoking, lowering salt intake, and increasing physical activity. He emphasizes that early, affordable preventive measures are essential to mitigate the impending CVD epidemic in these countries and prevent significant healthcare and economic strain.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

For thousands of years, humans have been using wildlife for commercial and subsistence purposes. Wildlife trade takes place at local, national and international levels, with different forms of wildlife, such as live animals, partly processed products and finished products. Wildlife is a vital source... of safe and nutritious food, clothing, medicine, and other products, in addition to having religious and cultural value. Wildlife trade also contributes to livelihoods, income generation and overall economic development.
However, wildlife trade can have detrimental effects on species conservation, depleting natural resources, impoverishing biodiversity and degrading ecosystems (Morton et al., 2021). Wildlife trade, whether legal or illegal, regulated or unregulated, can pose threats to animal health and welfare. It also presents opportunities for zoonotic pathogens to spill over between wildlife and domestic animals, and for diseases to emerge with serious consequences for public or animal health and profound economic impacts (IPBES, 2020; Swift et al., 2007; Smith et al., 2009; Gortazar et al., 2014; Stephen, 2021; Stephen et al., 2022; FAO, 2020). The risk of pathogen spillover and disease emergence is amplified with increased interaction between humans, wildlife and domestic animals. The risk of pathogen spillover has also been exacerbated by climate change, intensified agriculture and livestock production, deforestation, and other land-use changes. Wildlife trade is also a risk to ecosystem biodiversity via the introduction of invasive species (Wikramanayake et al., 2021). Therefore, increased effort must be put into understanding the potential consequences of the wildlife trade, mapping and analysing the adjacent risks, and implementing strategies to manage those risks. Reducing wildlife-trade risks not only helps to limit disease but also minimises the negative effects of invasive species. Between 1960 and 2021, invasive alien species caused estimated cumulative damage of around 116 billion euros across 39 countries in the European Union alone, despite strict import regulations (Haubrock et al., 2021). The effect of invasive species is extremely apparent.
