Silicosis in automobile foundry workers: a 29-year cohort study.

Objectives: The purposes were to determine the relationship between silicosis among foundry workers and their cumulative exposure to silica dust, and to establish a regression model to predict the risk for developing silicosis by a given length of employment and air concentrations of silica at worksites.

Methods: A 29-year cohort study was conducted, including all those employed for more than one year during January 1, 1980 to December 31, 1996 and all members of the cohort were followed-up to December 31, 2008. In total, 2009 workers of an automobile foundry in Shiyan, Hubei province were recruited in the study, 1300 at eight worksites including sand preparation, cast shakeout, and finishing, melting, moulding, core-making, overhead crane operation and pouring as exposed group, and the other 709 auxiliary workers at the same factory, such as electricians, inspectors, fitters, and so on, as control group.

[Re-analysis of occupational hazards in foundry].

Objective: To analyze systematically the characteristics of occupational hazards in the foundry, and provide precise data for epidemiology studies and control of occupational hazards in the foundry.

Methods: Data of airborne dust, chemical occupational hazards and physical occupational agents in environment in the foundry from 1978 to 2008 were dynamically collected. Mean concentration and intensity (geometric mean) of occupational hazards were calculated by job in different years.

[A pooling analysis of occupational sharp injury on clinical nurses in China].

Objective: To estimate the occupational sharp injury incidence and the diversity of the injury and the preventive control methods between the different levels of hospitals and the different areas of hospitals among nurses in China.

Methods: An electronic search of relevant online databases was undertaken. Twenty six retrospective investigation reports were identified from 209 reports based on the filter standards after a systematic review of them.
