Mammography Rates Remained Steady After Change in Guidelines
The proportion of women undergoing screening for breast cancer every year did not change after U.S. Preventive Services Task Force released recommendations saying there wasn't enough evidence to support routine mammograms for women in their 40s, according to a new study published in the journal Cancer. In 2009, the Task Force changed their recommendations to state that women aged 50 to 74 should have a mammogram every other year, and screenings for women under age 50 should be evaluated by each woman with her doctor, according to individual risk factors. "When there are conflicting versions of guidelines, providers may err on the side of screening," said David Howard, a health policy researcher from Emory University in Atlanta, in an interview with Reuters.

Latest HIV Vaccine Study Halted
The National Institutes of Health halted a study testing an experimental HIV vaccine after an independent review board found the vaccine did not prevent HIV infection and did not reduce the amount of HIV in the blood. The trial, started in 2009, is the latest in a series of failed HIV vaccine trials, according to Reuters. The halted study included more than 2,500 volunteers in 19 U.S. cities. Study populations included men who have sex with men and transgender people who have sex with men. Read more on HIV.
CDC's Food Safety Report Card: Some Foodborne Illnesses Spiked in 2012
The Centers for Disease Control and Prevention (CDC) recently released the "nation’s annual food safety report card," and it shows that 2012 rates of infections from two types of foodborne bacteria—campylobacter and Vibrio—have increased significantly when compared to a baseline period of 2006-2008, while rates of most others have not changed during the same period. The data are part of the Foodborne Diseases Active Surveillance Network report. Campylobacter infections have been linked to tranmission in many foods, including poultry, raw milk and produce. These infections were at their highest level since 2000, up 14 percent since 2006-2008. Vibrio infections, often associated with raw shellfish, were up 43 percent.
“The U.S. food supply remains one of the safest in the world,” said CDC Director Tom Frieden, MD, MPH. “However, some foodborne diseases continue to pose a challenge. We have the ability, through investments in emerging technologies, to identify outbreaks even more quickly and implement interventions even faster to protect people from the dangers posed by contaminated food.” Read more on food safety.
