Effects of occupational cobalt exposure on the heart in the production of cobalt and cobalt compounds: a 6-year follow-up.

Objective: It has been suspected that cobalt is toxic to the heart. It can cause cardiotoxicity in heavily exposed humans and in experimental systems. The issue of interest for this study is whether cobalt also affects the myocardium at occupational exposure levels.

Cancer incidence among Finnish male cobalt production workers in 1969-2013: a cohort study.

Background: There is inadequate evidence for the carcinogenicity of cobalt and cobalt compounds in humans. Consequently, the International Agency for Research on Cancer (IARC) has evaluated cobalt metal without tungsten carbide as possibly carcinogenic to humans (Group 2B). The aim of the study was to assess the risk of cancer among workers employed in a Finnish cobalt plant since the beginning of production in 1968.

Nine genera of Eucnemidae (Coleoptera) new to Peru, with a key to Peruvian genera.

Thirteen genera of Eucnemidae containing forty species were collected from the Iquitos region in Peru. Nine of the genera are new to the country: Rhagomicrus Fleutiaux, 1902, Adelorhagus Horn, 1890, Adelothyreus Chevrolat, 1867, Microrhagus Dejean, 1833, Dyscharachthis Blackburn, 1900, Heterotaxis Bonvouloir, 1871, Spinifornax Fleutiaux, 1926, Serrifornax Fleutiaux, 1926 and Maelodrus Fleutiaux, 1928. The previous eucnemid record from Peru contained eleven species in ten genera.

Perceived organizational justice as a predictor of long-term sickness absence due to diagnosed mental disorders: results from the prospective longitudinal Finnish Public Sector Study.

Organizational justice perceptions have been suggested to be associated with symptoms of mental health but the nature of the association is unknown due to reporting bias (measurement error related to response style and reversed causality). In this study, we used prospective design and long-term (>9 days) sickness absence with psychiatric diagnosis as the outcome measure. Participants were 21,221 Finnish public sector employees (the participation rate at baseline in 2000-2002 68%), who responded to repeated surveys of procedural and interactional justice in 2000-2004 along with register data on sickness absence with a diagnosis of depression or anxiety disorders (822 cases).

Psychosocial factors and well-being among Finnish GPs and specialists: a 10-year follow-up.

Background: Identifying factors that determine well-being among physicians may help to improve the functioning of hospitals and healthcare centres. We examined associations of psychosocial factors with psychological distress and sleep problems in Finnish general practitioners (GPs) and specialists.

Methods: In this prospective cohort study, data from repeated measures over 10 years, related to 886 physicians followed-up from 2000 to 2010 (the Finnish Public Sector Cohort Study).
