CDC: Teen Drinking and Driving Down 54% From 1991 to 2011
Drinking and driving by high school students ages 16 and older dropped 54 percent in the 20 years between 1991 and 2011, according to the U.S. Centers for Disease Control and Prevention. The CDC Vital Signs study showed that only 10 percent of the students in that age group drove after drinking in 2011. “We are moving in the right direction. Rates of teen drinking and driving have been cut in half in 20 years,” said CDC Director Thomas R. Frieden, MD, MPH. “But we must keep up the momentum -- one in 10 high school teens, aged 16 and older, drinks and drives each month, endangering themselves and others.” Read more on alcohol.
New Test Could Improve Genetic Screening in Newborns
A simple blood test could help doctors quickly diagnose and treat genetic conditions in newborns, according to a new study. The test is still in its early stages. Newborns are already screening for genetic disorders, but the tests can be costly and time-consuming, according to Stephen Kingsmore, MD, director of the Center for Pediatric Genomic Medicine at the Children's Mercy Hospital in Kansas City, Mo. If successful, this new test would speed up the process and allow for quicker treatment. "Genome analysis is moving from being a research tool that holds promise to being something that's ready to ... be used for real medical care in real patients," he said, according to HealthDay.

Study Links Aspirin, Slower Mental Decline in Older Women
A daily dose of aspirin could help slow mental decline in older women as it also helps protect against heart attacks, according to a study in the journal BMJ Open. The five-year Swedish study looked at approximately 700 women ages 70 to 92. The reason for the connection is not yet known, but may be related to a “neuro-protective effect” caused by the aspirin, according to study co-author Silke Kern, MD. The study found a correlation, but not causation, according to HealthDay. "I would not start taking aspirin because of this study," said Deepak Bhatt, MD, director of the integrated cardiovascular intervention program at Brigham and Women's Hospital in Boston. "This needs to be tested in a larger number of patients before we can say that aspirin has a role in preventing cognitive decline in women or men." Read more on heart health.
