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.

Chronic noncommunicable diseases (NCDs) are the number one cause of death and disability in the world. The term NCDs refers to a group of conditions that are not mainly caused by an acute infection, result in long-term health consequences and often create a need for long-term treatment and care. The...se conditions include cancers, cardiovascular disease, diabetes and chronic lung illnesses.
Many NCDs can be prevented by reducing common risk factors such as tobacco use, harmful alcohol use, physical inactivity and eating unhealthy diets. Many other important conditions are also considered NCDs, including injuries and mental health disorders.

South Africa is a mineral-rich country. Although the mining of these minerals generates wealth for the country, it also causes diseases in the mine workers who are exposed to harmful dust. Pulmonary silicosis, the disease most commonly caused by exposure to crystalline silica dust, was described in ...South African gold miners in the early 1900s not many years after gold-mining commenced. Most studies since then have been cross-sectional, with only one large cohort study being conducted on white miners; long-term trends have not been reported. Currently, South Africa has one of the highest rates of silicosis in the world.

Occupational exposures to respirable crystalline silica occur in a variety of
industries and occupations because of its extremely common natural occurrence and the wide uses of materials and products that contain it. At least 1.7 million U.S. workers are potentially exposed to respirable crystallin...e silica [NIOSH 1991], and many are exposed to concentrations that exceed limits defined by current regulations and standards.

This study compared clinical and autopsy findings for three asbestos-related diseases (asbestosis, mesothelioma and lung cancer) in former asbestos mineworkers, and explored factors that influenced agreement between clinical and autopsy findings using data from two compensation systems. In South Afr...ica, statutory compensation for occupational lung diseases in mineworkers makes provisions for autopsy examinations of the cardio-respiratory organs at the National Institute for Occupational Health (NIOH) in Johannesburg. In addition, the Johannesburg-based Asbestos Relief Trust and Kgalagadi Relief Trust (the “Trusts”) compensate individuals with defined asbestos-related diseases who worked in or lived near qualifying asbestos mining or processing operations. The Trusts also compensate dependents of deceased qualifying mineworkers and therefore encourage statutory autopsies for the detection of previously undiagnosed asbestos-related disease or disease that may have progressed to higher compensation grades.

The article "A 20-year follow-up study on chronic respiratory effects of exposure to cotton dust" evaluates the long-term impact of cotton dust exposure on respiratory health. It followed a cohort of Chinese cotton and silk workers from 1981 to 2001, comparing lung function and symptoms. Results sho...wed that cotton workers experienced greater declines in lung function and persistent respiratory symptoms compared to silk workers. The study found that exposure to airborne endotoxins in cotton dust was strongly linked to chronic respiratory impairment. It highlighted that stopping exposure helped improve lung function, particularly in non-smoking men, while smokers continued to show negative effects.

The Mediclinic article on silicosis provides an overview of this occupational lung disease caused by inhaling silica dust. It explains that inhaled silica particles lead to lung scarring and nodule formation, progressively impairing breathing. The article outlines symptoms such as shortness of breat...h, severe cough, fatigue, loss of appetite, chest pains, and fever. Diagnosis involves a medical examination, detailed occupational history, lung function tests, and imaging like chest X-rays or CT scans to detect lung scarring and nodules. While silicosis is irreversible with no specific cure, management focuses on preventing further silica exposure and treating complications. Preventive measures include maintaining high occupational health standards to control silica dust exposure.

The article "Under- and over-diagnosis of COPD: a global perspective" reviews the worldwide variation in the prevalence of chronic obstructive pulmonary disease (COPD) and issues related to its misdiagnosis. It highlights that COPD is under-diagnosed due to factors such as limited access to spiromet...ry and variable diagnostic criteria, especially in low- and middle-income countries. Conversely, over-diagnosis often results from reliance on non-standard criteria or inadequate spirometry use. The article discusses key risk factors, including age, gender, exposure to pollutants, and comorbidities, and emphasizes the need for standardized diagnostic practices to better address and manage COPD globally.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

Time has seen management for Cystic Fibrosis (CF) advance drastically, most recently in the development of the disease-modifying triple combination therapy ivacaftor/tezacaftor/elexacaftor. There is currently limited evidence regarding both the global epidemiology of CF and access to this transforma...tive therapy - and therefore where needs are not being met. Therefore, this study aims to define gaps in access to CF treatment. The results show that a significant CF patient burden exists in countries where disease-modifying drugs are unavailable, and final figures are likely underestimates. This analysis shows the potential to improve rates of diagnosis and treatment for CF, so a higher percentage of patients receive the most effective triple combination treatment.
