Night shift work and stomach cancer risk in the MCC-Spain study.

Objectives: Night shift work has been classified as a probable human carcinogen by the International Agency for Research on Cancer, based on experimental studies and limited evidence on human breast cancer risk. Evidence at other cancer sites is scarce. We evaluated the association between night shift work and stomach cancer risk in a population-based case-control study.

[Data completeness in the Spanish official medical record for asbestos-exposed workers].

The medical record form included in Spanish Royal Decree 396/2006 (Annex 5), regulating health protection for workers exposed to asbestos, is an important source of information on the health effects of asbestos exposure. The frequency and percentage of correctly filled data was assessed in a sample of 400 medical records. Overall, data completeness was low, especially regarding individual identification data, occupational history and results of radiographic studies.
