Trends in pneumoconiosis in Brazil, 1979–2019

Abstract

Background Pneumoconiosis is a lung disease related to exposure to dust in the workplace. The disease can induce irreversible damage to health, especially in lung tissue, and can cause progressive and permanent physical disabilities. Aims This study evaluated the temporal and spatial distribution of mortality rates (1979–2019) and hospital admissions (1995–2019) for pneumoconiosis in Brazil. Methods The outcomes were hospitalization and death due to pneumoconiosis: codes 500–506 according to the ICD-9 and J60–J66 according to the ICD-10. Data from this retrospective ecological study were collected from the Brazilian Ministry of Health database. Results Hospitalization for pneumoconiosis has decreased in all regions of Brazil. Hospitalizations occurred predominantly in men aged over 40 years. Death rates showed a temporal increase in all regions. Deaths occurred predominantly in men aged over 50 years. The highest hospitalization and death rates were in the states of the Midwest and South Regions. Conclusions Pneumoconiosis is a preventable occupational disease, and ongoing occurrences of hospitalizations and deaths highlight the importance of inspecting industries and controlling occupational and environmental exposures.

Survival and disease burden analyses of occupational pneumoconiosis during 1958–2021 in Huangshi city, China: a retrospective cohort study

“…Compared with stages I and II, the survival time of patients at stage III is much shorter, which is also consistent with previous studies [ 25 – 27 ]. This is because pneumoconiosis is a chronic disease with no effective cure, and its progression is accompanied by other complications and fibrosis of the lungs, leading to damage to lung function and affecting patient survival time [ 28 ].…”

Ethnic/Racial Disparity in Mortality from COVID-19: Data for the Year 2020 in Brazil

“…Even so, with the data available for extraction, it was verified that the highest age-standardized mortality rate in Salvador was among blacks. This limitation related to underreporting and poor filling of information is common in ecological studies, especially in countries that face difficulties in recording health information, such as Brazil (Da Silva Júnior & Dos Santos, 2022 ; Penteado et al, 2022 ). Even so, these studies with national coverage make it possible to point out problems and priority issues for scientific studies and especially for actions of the regional and national health sectors.…”

Determination of the model of a powered air-purifying respirator for researching its operational modes

“…PAPR (Powered Air Purifying Respirators). Їх рекомендують використовувати на виробництві, де наявне високе забруднення повітря пилом, хімічними речовинами, аерозолями [3,4]. Також в умовах пандемії COVID-19 подібні пристрої є актуальними для застосування медичними працівниками [5][6][7][8], з урахуванням відповідних вимог до експлуатації [9].…”
