This study explored the associations between biomechanical and psychosocial work factors and musculoskeletal symptoms in vineyard workers. ⋯ These results underlined that both biomechanical and psychosocial work factors may play a role in musculoskeletal pain among vineyard workers. Prevention policies focusing on both biomechanical and psychosocial work exposures may be useful to prevent musculoskeletal symptoms.

To determine the incidence rate of work-related aggression and violence (WRAV) against doctors and investigate risk factors and psychological influences of WRAV doctors. ⋯ Doctors encountered WRAV at an incidence rate of 0.20×10(-3) per practice hour, and some of them might develop PTSD. Countermeasures are required to maintain sound health and safe workplaces for doctors.

Comparative Study
Two- and 13-week inhalation toxicities of indium-tin oxide and indium oxide in rats.
Two- and 13-week inhalation toxicities of indium-tin oxide (ITO) and indium oxide (IO) were characterized for risk assessments of workers exposed to ITO. ⋯ Persistent pulmonary lesions including alveolar proteinosis and macrophage infiltration occurred after 2- and 13-week inhalation exposures of rats to ITO and IO. Fibrosis of alveolar wall developed later. These lesions occurred after ITO exposure at the same concentration as the current occupational exposure limit in the USA and at blood indium levels below the biological exposure index in Japan for indium.

To investigate the injury of cell tight junctions and change in actin level in the alveolus epithelial cells of the lung after perfluoroisobutylene (PFIB) exposure and the role of myosin light chain kinase (MLCK) in the injury. ⋯ At an earlier stage, the increased permeability of the blood-air barrier after PFIB exposure is probably the result of injury of cell tight junctions that acts in concert with later changes in actin, resulting in an increase in permeability. MLCK could be a potential target for novel drug development for relief of acute lung injury.

To estimate proportions of injuries that are attributable to the work environment (excess fractions) among economically active men and to identify industries associated with an elevated injury risk. ⋯ There are substantial industrial inequalities in injury rates among male workers in Denmark. The size of the inequalities differs between body regions.
