Researchers at Harvard Medical School say surgical site infections and pneumonia caused by ventilators are two of the most common and costly kinds of health-care associated infections. Researchers say while steps have been taken to reduce the number of preventable infections, more needs to be done.
A new, 10-year study finds women in their 40 and 50s with asthma are hospitalized more than twice as often as men in the same age group. Researchers say until puberty, boys have higher rates of asthma than girls, but during the menopausal years, asthma becomes more of a women's health issue.
And a new report finds teenagers who see their friends smoking and drinking in photos on Facebook and other social networking sites -- are more likely to smoke and drink themselves.
