Study: IVF Does Not Affect Risk of Breast, Gynecological Cancers
In vitro fertilization (IVF) does not increase a woman’s risk of breast and gynecological cancers, according to a new study in the journal Fertility & Sterility. Researchers looked at the medical records of 67,608 women who underwent IVF between 1994 and 2011 and 19,795 women who sought treatment, did not receive it. They found no increase in the chance of being diagnosed with breast or endometrial cancer and only a slight increase in ovarian cancer depending on the times treated, which might have been the result of chance. Previous studies had linked IVF to increased risk of breast cancer and borderline ovarian tumors. Read more on cancer.
Studies Link Excessive Television as Kids, Violence as Adults
Reducing the amount of violent television programming a child watches may also reduce their aggression levels, according to two new studies in the journal Pediatrics. A New Zealand study found higher rates of criminal convictions in people who had watched more television as children, while a U.S. study found kids who watched “pro-social” programming were better behaved than their peers who watched regular programming. "It's not just the bad behaviors that they get from TV. They can get good behaviors, too," said the U.S. study's lead author, Dimitri Christakis, MD, MPH, director of the Center for Child Health, Behavior and Development at Seattle Children's Research Institute. The link between television and violence has been difficult for researchers to study because of the presence of so many other factors, but the findings do support previous research showing a link between watching too much television early in life and antisocial problems, according to study co-author Bob Hancox, MD, an associate professor in the department of preventive and social medicine at the University of Otago in Dunedin.

NIH: Diabetes Control Much Improved in Past Two Decades
People are increasingly meeting the recommended goals for the top markers of diabetes control, according to a new study in the journal Diabetes Care. The "ABC's" of diabetes control include A1C (which assesses blood sugar levels), blood pressure and cholesterol. About 19 percent of people with diabetes met all three of the goals in 2010, up from only 2 percent in 1988. The National Institutes of Health and the U.S. Centers for Disease Control and Prevention conducted and funded the study. Still, the researchers say continued improvement is needed, especially for younger people and certain minority groups. Read more on diabetes.
