The organizational structure and the environment of a medical institution can hide a low-quality life of a physician. This study examines the relationship between the hospital work environment and physicians' job satisfaction and motivation when working in a large public academic hospital.

Traffic-related air pollution and perinatal mortality: a case-control study.

Background: Ambient levels of air pollution may affect the health of children, as indicated by studies of infant and perinatal mortality. Scientific evidence has also correlated low birth weight and preterm birth, which are important determinants of perinatal death, with air pollution. However, most of these studies used ambient concentrations measured at monitoring sites, which may not consider differential exposure to pollutants found at elevated concentrations near heavy-traffic roadways.
