Night work and breast cancer – more evidence
Recent research has suggested a moderate link between night work and breast cancer in women, mainly through case–control studies. Swedish researchers undertook this study in order to provide new information from cohort data through investigating the association between the number of years with night work and breast cancer among women exposed to night shift work. The researchers interviewed and followed up 13,656 women from the Swedish Twin Registry, with 3404 exposed to night work. Taking into account
The results showed a significant association between exposure to night work for >20 years and breast cancer in women who were followed up to the age of 60 years. For the complete group, independent of exposure duration, there was a trend in the same direction.

Pig farm workers at high risk of staph
It has been found that pig farm workers are six times as likely to carry multidrug-resistant Staphylococcus aureus as workers who have no contact with pigs. In one of the largest studies of staph in livestock workers, researchers found that contact with farm animals, particularly pigs, generally left workers more likely to carry the infectious bacteria, including drug-resistant varieties such as MRSA. Researchers monitored 1,342 people from Iowa and the staph they carried for up to 17 months.
They found that a worker's chance of carrying staph increased with the number of pigs contacted. The farms in the study housed an average of 355 pigs, while the US average is about 2,300. Consequently, they cautioned that their findings, published April 29 in Clinical Infectious Diseases, may underestimate the health risks.
