A recent report from the World Bank suggests that violence against women is responsible for one out of every five working days lost. Research found a third of women aged 40-50 had been abused as children, with common symptoms like joint pain and fatigue more likely in those who were beaten or sexually abused.
A study suggests that dietary fat is unlikely to cause breast cancer, but rather depletes the body of an essential nutrient that protects against the disease. The research concludes that age and oestrogen also play a role in breast cancer development.
Researchers found that Canadians are less likely to retire in a year where working an additional year would increase their lifetime benefits significantly. The study shows that seniors recognize the importance of retiring at age 60 due to incentive systems in place.
A study by University of Toronto researchers found that repeated exposure to azole drugs can lead to the development of drug-resistant yeast infections. About 75% of women between 18 and 35 will experience at least one yeast infection caused by Candida albicans, a common type of yeast fungus.
