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 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.

The article "Economic Burden of Chronic Obstructive Pulmonary Disease (COPD): A Systematic Literature Review" examines the financial impact associated with moderate-to-very severe COPD. The review analyzes studies published between 2006 and 2016 that discuss healthcare resource utilization (HRU), di...rect costs, and indirect costs related to COPD, with a focus on Europe and North America. It highlights that direct costs, including hospitalizations and medical treatments, increase with the severity of COPD and the frequency of exacerbations. Multivariate analyses identify key factors driving these costs, such as comorbidities and prior treatment history. The findings underscore the significant economic burden of COPD on healthcare systems and emphasize the need for improved management strategies to reduce costs and optimize patient care.
