• Biennial and yearly mammograms give older women same benefit

  Among older women, getting a mammogram every two years was just as beneficial as getting a mammogram annually, and led to significantly fewer false-positive results, according to a Breast Cancer Surveillance Consortium (BCSC) study including patients and researchers from Group Health. The national study of more than 140,000 women between ages 66 and 89 is in the Journal of the National Cancer Institute.
• Less reaction to DTaP vaccine given in kids’ thighs than arms

  Children age 12 to 35 months who receive DTaP vaccine in their thigh muscle rather than their arm are around half as likely to be brought in for medical attention for an injection-site reaction.

For most people in the study, e-published in advance of print in Obesity Surgery, diabetes either never remitted after gastric surgery or relapsed within five years.

  The U.S. Preventive Services Task Force recommended in 2009 that primary care clinicians should screen adolescents for depression. But a positive result or screen does not mean that every young person needs active treatment—including psychotherapy and medication—for depression, based on a new study in the November 19 Pediatrics led by Laura Richardson, MD, MPH, of Seattle Children’s Research Institute.
