Public Health News Roundup: October 18
CDC Flu Reports to Resume Later Today
The U.S. Centers for Disease Control and Prevention (CDC) reported late yesterday that it has resumed analysis of influenza surveillance data and testing of influenza laboratory specimens collected during the 16-day government shut-down. An abbreviated FluView report summarizing the data for the most recent week (October 6-12) will be posted on Friday, October 18. At a later date, reports summarizing influenza surveillance data for September 22-October 5 will also be posted. Weekly Friday posting of the full FluView report for the 2013-2014 season will begin again on October 25. In the United States, flu season typically runs September through April and both private doctors and public health clinics currently have large supplies of this year’s flu vaccine on hand.

Brain May Flush Out Toxins During Sleep
A new study funded by the U.S. National Institutes of Health finds that a good night’s rest may literally clear the mind. The study, conducted in mice, showed—for the first time, according to the researchers—that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. The researchers say that suggests a new role for sleep in health and disease. The study, published in Science, shows that during sleep a plumbing system called the glymphatic system may open, letting fluid flow rapidly through the brain. The researchers studied the system by injecting dye into the cerebrospinal fluid of mice and watching it flow through their brains while simultaneously monitoring electrical brain activity. The dye flowed rapidly when the mice were either asleep or anesthetized, but barely flowed when the same mice were awake. The researchers also inserted electrodes into the brains of the mice to directly measure the space between brain cells and found it increased by 60 percent when the mice were asleep or anesthetized. Researchers say the applications may apply to general health as well as have implications for neurological disorders. Read more on research.
New Report Offers Suggestions for Creating Healthier Neighborhoods
Again and again, research shows that our environment—where we live and what behaviors it fosters—has a profound impact on our health. Realizing this, a new report from the Prevention Institute offers interviews with fifty leaders in multiple sectors, including transportation, housing and public health on how to create healthy, safe and equitable neighborhoods. The goal of the report, Towards a 21st Century Approach: Advancing a Vision of Prevention and Public Health, is to spark an active and ongoing national dialogue about the subject. It was made possible through funding from the Robert Wood Johnson Foundation. Read more on smart growth.
