The course aims to cover the types of NCDs and risk factors, the challenges of delivering NCD services in primary health care, elements of WHO technical packages (PEN and HEARTS) for NCDs and how to adapt these packages in primary health care.
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.

The burden of asthma in Africa is high, and yet the disease is not universally prioritised. Data on allergic asthma and its impact on asthma morbidity are limited in Africa. Our aim was to describe the distribution of skin prick positivity among asthmatics in Eastern Africa.
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.

Our awareness necessity of cystic fibrosis (CF) significantly predates our ability to comprehend the molecular factors that underpin its cause and affect prognosis. The dire warning “Woe to that child which when kissed on the forehead tastes salty. He is bewitched and soon must die” has been cir...culating since the 1800s. CF patients taste salty when kissed because an elevated level of sweat chloride is a hallmark of the disease. If untreated, they rarely make it past their first birthday. Typical presentation also includes failure to thrive caused by pancreatic insufficiency and chronic recurrent chest infections.

Asthma is one of the neglected diseases in Africa with a high prevalence. Allergic fungal diseases have been reported to complicate asthma progression and treatment outcomes. However, data about fungal asthma and its associated complications are limited in Africa. We aimed to estimate the burden of ...fungal asthma among adults and children in Africa using a systematic review.

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.
