Strokes Fall Among Older Americans
Fewer older Americans are having strokes and those who do have a lower risk of dying from them, according to researchers at the Johns Hopkins Bloomberg School of Public Health. The study, published in JAMA, followed close to 15,000 stroke-free patients ages 45 to 64, beginning in the 1980s and ending in 2011. It found a 24 percent overall decline in first-time strokes in each of the last two decades and a 20 percent overall drop per decade in deaths after stroke. However, the decline was found mainly in people over age 65, with little progress in reducing the risk of strokes among younger people. The researchers say the decrease in stroke incidence and mortality is partly due to more successful control of risk factors such as blood pressure, smoking cessation and use of statin medications for controlling cholesterol, but that more efforts are needed to reduce strokes in younger people, including reducing obesity and diabetes and increasing physical activity.

Study: Insufficient Sleep Can Harm Memory
Lack of sleep, currently considered a public health epidemic in the United States, can also lead to errors in memory, according to a new study in Psychological Science. The study found that participants who didn’t get a full night’s sleep were more likely to make mistakes on the details of a simulated burglary they were shown in a series of images. “We found memory distortion is greater after sleep deprivation,” said Kimberly Fenn, an associate professor of psychology at Michigan State University and a co-investigator of the study. “And people are getting less sleep each night than they ever have.” The U.S. Centers for Disease Control and Prevention has linked the insufficient sleep epidemic to car crashes, industrial disasters and chronic diseases such as hypertension and diabetes.

The U.S. Environmental Protection Agency (EPA) has recently released a new graphic design available for use by insect repellent makers to more easily show how long the product is effective. “We are working to create a system that does for bug repellents what SPF labeling did for sunscreens,” said Jim Jones, Assistant Administrator of the Office of Chemical Safety and Pollution Prevention. “By providing vital information to consumers, this new graphic will help parents, hikers and the general public better protect themselves and their families from serious health threats caused by mosquitoes and ticks.” The release of the graphic design was accompanied by a joint statement from the EPA and the U.S. Centers for Disease Control and Prevention (CDC) urging the public to use insect repellents and take other precautions to avoid biting insects that carry serious diseases, including Lyme and West Nile virus. Incidence of insect-borne diseases is on the rise, according to the CDC. In order to place the new graphic on their labels, manufacturers must submit a label amendment, including test results on effectiveness. The public could see the graphic on repellent products early next year. Read more on infectious disease.
