Anthracosis is an occupational disease which is caused by long-term inhalation of coal and rock dust. We present a case of epicardial anthracosis in a patient who underwent coronary artery bypass graft surgery for coronary artery disease. This is the first case of anthracosis related to the heart in the literature to the best of our knowledge. This case report emphasizes the systemic dissemination of inorganic particles such as carbon in the human body.

BACKGROUND: Previous studies show that workplace support for sun-protective behaviors plays an important role in the actual sun-protective behavior of outdoor workers. Therefore, our aim was to examine perceived workplace support (organizational and social support) in relation to different sun-protective behaviors. METHODS: A Germany-wide sample of outdoor workers (n = 485) was surveyed via telephone. We analyzed associations of workplace support with sun-protective behaviors, sociodemographic, and occupational characteristics, occupational sun exposure, and concerns about sun...

BACKGROUND: We developed a systematic, data-driven approach to estimate metrics of occupational exposure to lead to aid in epidemiologic analyses in a case-control study of kidney cancer. METHODS: Probability of exposure to ten lead sources was assigned using decision rules developed from an extensive literature review and expert judgement. For jobs with >50% probability of exposure, we assigned source-specific frequency based on subjects' self-reported task frequencies or means of subjects' job-groups and source-specific intensity estimates of blood lead (μg/dL)...

BACKGROUND: Shift work and psychosocial stressors may contribute to higher metabolic syndrome (MetS) incidence. Few studies investigated whether the presence of both factors simultaneously has a synergic effect on risk of MetS. METHODS: This cross-sectional analysis used baseline data (2008-2010) for 10 960 current workers from ELSA-Brasil. Multiple logistic regression was used to estimate independent associations between shift work and job strain and MetS. An interaction between these factors was tested by including a multiplicative term in the final model...

The purpose of this commentary is to bring the neglected phenomenon of subradiological silicosis and its implications to the attention of readers. We define subradiological silicosis as silicosis detectable on pathological examination of lung tissue but not visible radiologically. For extent of the phenomenon, we draw on a study using a large South African autopsy database of deceased miners and chest radiographs taken in life. At an International Labour Organization threshold of >1/0 only 43% of all pathologically detected cases were detected on chest radiograph, and only 62% of those classified on pathology as "moderate or marked" silicosis...
