Given the intimate association between silicosis and tuberculosis, understanding the epidemiology of the South African gold mining industry silicosis epidemic is essential to current initiatives to control both silicosis and tuberculosis in this population, one of the most heavily affected globally.

The study’s objectives were to compare the prevalence of silicosis among working black gold miners in South Africa during 2004–2009 to that of previous studies, including autopsy series, and to analyse the influence of silicosis and/or tuberculosis on exiting employment.

Asthma is the most common chronic respiratory disease among school-going adolescents worldwide. However, the burden of severe asthma is highest in Sub-Saharan Africa. This study aimed to explore teachers’ perceptions of asthma care across six African countries. We conducted focus group discussions

(FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

Asbestos-related diseases in mineworkers: a clinicopathological study

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.

A 20-year follow-up study on chronic respiratory effects of exposure to cotton dust
Wang, X-R.; Zhang, H-X.; Sun, B-X.; et al.

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 condition increased significantly. Risk factors for asthma and severe cases include smoking, pet exposure, outdoor pollution, and living in informal housing. Despite these trends, underdiagnosis remains a concern, as only one-third of adolescents with current or severe asthma had been formally diagnosed. The article emphasizes the need for better public health strategies to address environmental exposures and improve asthma diagnosis and treatment.

Under- and over-diagnosis of COPD: a global perspective
Ho T., Cusack R.P., Chaudhary N. et al.

(2019)

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.

Lack of information about economic burden of COPD is a major cause of lack of attention to this chronic condition from governments and policymakers.
The article "The burden of chronic obstructive pulmonary disease and its attributable risk factors in the Middle East and North Africa region, 1990–2019" provides an analysis of the prevalence, mortality, and disability-adjusted life-years (DALYs) due to COPD in the MENA region from 1990 to 2019.
...
The study uses data from the Global Burden of Disease (GBD) 2019 and shows that while age-standardized death and DALY rates have decreased over 30 years, COPD remains a significant health issue, especially among older populations. The main risk factors identified are smoking, ambient particulate pollution, and occupational exposure. The research underscores the impact of socioeconomic factors and recommends targeted public health initiatives to reduce the burden.

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.

to 24.8% and an average pooled prevalence of 8%. The analysis points out that smoking, exposure to biomass smoke, and age are key risk factors. The study emphasizes the need for improved diagnosis and awareness, as COPD often remains underdiagnosed and undertreated in SSA. The authors call for coordinated efforts from clinicians, researchers, and policymakers to address these issues and reduce exposure to preventable risk factors.
