Public Health News Roundup: October 4
Four U.S. Regions on Alert for Severe Weather this Weekend
Severe weather is expected to impact at least four regions of the United States this weekend. That includes a tropical storm—downgraded from a hurricane for now—in the Gulf Coast; a tornado threat in the Midwest; early snow in the West that, in part because trees still have leaves that can be weighed down by wet snow, could lead to power outages; and spreading fires in California fueled by dry weather. The Federal Emergency Management Agency (FEMA) has already recalled some furloughed staff to prepare for the storms expected on the Gulf Coast. Read more on preparedness.
Study: Unnecessary Antibiotic Prescriptions Remain High, Endanger Public Health
Despite ongoing efforts by the U.S. Centers for Disease Control and Prevention (CDC) and other public health organizations, doctors continue to overprescribe antibiotics for sore throats, increasing the risk of the development of antibiotic-resistant bacteria, according to a new study in JAMA Internal Medicine. “Our research shows that while only 10 percent of adults with sore throat have strep, the only common cause of sore throat requiring antibiotics, the national antibiotic prescribing rate for adults with sore throat has remained at 60 percent,” said senior author Jeffrey A. Linder, MD, MPH, a physician and researcher in the Division of General Medicine and Primary Care at Brigham and Women’s Hospital. “For acute bronchitis, the right antibiotic prescribing rate should be near zero percent and the national antibiotic prescribing rate was 73 percent.” The researchers said the findings demonstrate the need to study and implement new interventions to reduce unnecessary antibiotic prescriptions.

Daily Walks Can Reduce Breast Cancer Risk for Older Women
Post-menopausal women can reduce their risk of developing breast cancer through physical activity as simple as a daily walk, according to a new study in Cancer Epidemiology, Biomarkers & Prevention. More intense exercise may have an even more profound impact. "The nice message here is, you don't have to go out and run a marathon to lower your breast cancer risk," said study researcher Alpa Patel, senior epidemiologist at the American Cancer Society, which funded the study. "Go for a nice, leisurely walk an hour a day to lower risk.” However, the study authors noted that they found only a correlation, not a causation, so further study is needed. Experts believe the reason exercise reduces breast cancer risk is related to hormones; they also recommend maintaining a healthy body weight and minimizing the consumption of alcohol as ways to reduce the risk of breast cancer.
