Accidentes de trabajo mortales y enfermedades profesionales en la minería (Régimen General). Perú: 2010-2019 / Fatal work accidents and professional diseases in mining (General Regime). Peru: 2010-2019

Se analiza el comportamiento de los accidentes de trabajo mortales (ATM) y de las enfermedades profesionales (EP), en relación con las empresas del régimen general en la minería peruana, durante los años 2010 al 2019. Se realizó un estudio transversal de la base de datos del Ministerio de Energía y Minas. El estudio incluyó las notificaciones de accidentes de trabajo mortales y de las enfermedades profesionales reportadas en esa década por las empresas mineras del régimen general; del 2010 al 2019 para los ATM, y entre 2011- 2019 para las EP, a nivel nacional. Resultados: De 422 ATM notificados entre 2010-2019 se determinan cuatro rangos, considerando 126 empresas. El rango D (dos empresas) son el 2% pero las que presentan la mayor siniestralidad laboral. La empresa D1 acredita 29 ATM y la empresa D2 tiene19 ATM, ambas asumen el 11.34% del total de los ATM en la década analizada. El rango A, son 95 empresas, conforman el 75% del total y presentan entre 1 a 3 ATM para el mismo periodo. El 61% de trabajadores víctimas de ATM son de contratistas y conexas; mientras que el 39% son ATM de las empresas principales. Entre 2011-2019 se notificaron 40,001 EP en las empresas mineras, trabajadores con menos de un año registran EP y mayores de 55 años tienen una curva pronunciada de EP. El 1% son trabajadoras mineras y el 99% son trabajadores. Se necesita mayor investigación sobre las EP en el sector minero(AU)

To analyse the behavior of fatal work accidents (ATMs for its acronym in Spanish) and occupational diseases (EPs), in companies under the general regime of the mining sector in Peru during the years 2010 to 2019. A cross-sectional study was carried out using the database from the Ministry of Energy and Mines (MINEM). The study included notifications at the national level of ATMs (2010-2019) and EPs (2011 to 2019) reported by the mining companies under the general regime. Results: Of 422 ATMs reported by 126 companies between 2010-2019, four range categories were determined. Rank D grouped two companies (representing only 2%) that had the highest occupational accident rate. Company D1 reported 29 ATMs and company D2 reported 19 ATMs, together accounting for 11.34% of the total number of ATMs during the study period. Rank A consisted of 95 companies (representing 75%) and reporting between 1 to 3 ATMs for the same period. Contractor and outsourcing companies reported 61% of workers victims of ATMs, while main companies reported 39% of ATMs. Between 2011-2019, 40,001 EPs were reported in mining companies, workers under one year reported EPs, and workers over 55 years of age had a steep EP curve. Female workers represent 1% of mining workers and 99% are male workers. More research is needed on EPs in the mining sector(AU)

Silicose em ex-mineiros de extração de cobre / Silicosis among former copper mine workers

Introdução: Existe escassez de estudos brasileiros analisando o efeito da exposição contínua à sílica em ex-trabalhadores de minas de cobre. Os achados radiográficos produzidos pela silicose têm recebido atenção médica especial. O objetivo deste estudo foi caracterizar clínica e radiologicamente a silicose em ex-mineiros de extração de cobre. Métodos: Estudo transversal, com 100 ex-mineiros de extração de cobre. Os dados foram coletados através de entrevista pessoal, dados clínicos ocupacionais e exames radiológicos. Na entrevista foi verificada a idade, sexo e o tempo de trabalho na extração de cobre. Os pacientes que já haviam realizado exame radiológico de tórax trouxeram estes para comparação. Os ex-mineiros assinaram um termo de consentimento para a realização dos exames radiológicos os quais foram aplicados pelo radiologista que os interpretou. Resultados: Entre os 100 ex-mineiros 35% são portadores de silicose, 11% apresentaram alterações pulmonares que podem ter outras causas, como tuberculose, enfisema e doença broncopulmonar obstrutiva crônica e 54% não apresentaram nenhuma alteração pulmonar. Conclusão: A alta frequência de silicose encontrada reforça a recomendação de suspender a exposição à sílica tão logo se tenha uma radiografia sugestiva da doença

Introduction: There is scarcity of Brazilian studies analyzing the effect of continuous exposure to silica in former workers of copper mines. The radiographic images produced by silicosis have received special medical attention. The aim of this study was to characterize clinical and radiological silicosis in former copper mine workers. Methods: Cross-sectional study of 100 ex-copper miners. Data were collected through personal interview, occupational clinical data, and radiological examinations. In the interviews we recorded age, gender and working time on the extraction of copper. Patients who had previously undergone chest X-rays have brought these for comparison. The ex-miners signed a consent form to be submitted to Xrays, which was applied by the same radiologist that interpreted them. Results: Among the 100 ex-miners 35% are diagnosed with silicosis, 11% had lung abnormalities that may have other causes such as tuberculosis, emphysema and chronic obstructive pulmonary disease, and 54% had no pulmonary change. Conclusion: The high incidence of silicosis found reinforces the recommendation to suspend silica exposure as soon as there is a radiograph suggestive of the disease

Influencia de la obesidad en los costos en salud y en el ausentismo laboral de causa médica en una cohorte de trabajadores / Influence of obesity on health care costs and absenteeism among employees of a mining company

Background: The health associated costs of obesity can represent between 2 percent and 9 percent of the total health costs of a given country. Aim: To assess the impact of obesity on health care costs and absenteeism in a cohort of mine workers. Patients and wethods: Prospective study of 4.673 men, employees of a mining company, aged 49 ± 7 years that were followed for 24 ± 11 months. Total health care cost and days of sick leave were recordedfor each individual. The association between obesity and these variables was analyzed by logistic regression adjusting for co-morbidities, age and other variables. Results: Mean annual health care costs for obese workers were 17 percent higher (p <0.001) compared to workers with normal weight and 58 percent higher (p <0.001) for workers with severe and morbid obesity. Mean annual days of sick leave increased by 25 percento in the obese (p =0.002) and by 57 percento in subjects with severe and morbid obesity (p <0.001). For health care costs the most significant predictors were: presence of diabetes mellitus (Odds ratio (OR) 6.21, 95 percento confidence intervals (95 percent CI) 4.9 to 7.9), hypertension (OR 3-99; 95 percent CI3-4 to 4.6) and severe and morbid obesity (OR 2.55, 95 percento CI 1.9 to 3-4). For absenteeism the most significant predictors were: presence of diabetes mellitus (OR 1.58, 95 percent> CI 1.2 to 2.0), hypertension (OR 1,34, 95 percent> CI 1.2 to 1.6) and severe and morbid obesity (OR 1.50, 95 percento CI 1.1 to 2.1). Conclusions: Obesity increases significantly health care costs and absenteeism.

Associaçäo positiva e estatisticamente significante (p<0,001) entre produçäo de ouro e IPA foi observada em análise multivariada, ainda que controlada por gastos financeiros. Esse achado contribui para a elucidaçäo da tendência de reduçäo da malária em MT, observada na última década

Maximal expiratory flow volume curve in quarry workers.

Maximal Expiratory Flow Volume (MEFV) curves were recorded with a computerized Spirometer (Med Spiror). Forced Vital Capacity (FVC), Forced Expiratory Volumes (FEV), mean and maximal flow rates were obtained in 25 quarry workers who were free from respiratory disorders and 20 healthy control subjects. All the functional values are lower in quarry workers than in the control subject, the largest reduction in quarry workers with a work duration of over 15 years, especially for FEF75. The effects are probably due to smoking rather than dust exposure.

Cáncer broncopulmonar entre trabajadores expuestos a arsénico: un estudio de casos y controles / Bronchial-pulmonary cancer among workers exposed to arsenic: a control case study

Case-control methodology was used to assess lung cancer risk from exposure to arsenic in air, employing data from former workers in different units at the Chuquicamata copper mine and smelter complex. Thirty two workers from this complex were identified among the lung cancer deaths that occurred in the northern region of Chile belween 1987 and 1991. Each case was matched on age and sex, with controls that had a similar date of enrolment in the company. Available data on arsenic concentrations in air for six work sites were compiled from 1952 to 1991 and these were used to categorize the workplaces: Administrative Area (1,6 µg/mü), Mine (2,3 µg/mü), Oxid Plant (3,1 µg/mü), Workshop and Services (9,8 µg/mü), Sulphur Plant (8,4 µg/mü) and Smelter (201,7 µg/mü). The results indicate an Odds Ratio of 5.7 (Fisher's p=0,016) of dying from lung cancer among workers of the smelter compared with the rest of the workers
