FDA Uses ‘Substantial Equivalence’ Standard to Authorize Two New Tobacco Products, Deny Four Others
The U.S. Food and Drug Administration (FDA) has, for the first time, utilized the substantial equivalence pathway to deny the marketing of four new tobacco products and allow the marketing of two new ones. FDA was granted the authority under the Family Smoking Prevention and Tobacco Control Act of 2009. Manufacturers can seek approval of new products by showing they are substantially equivalent to other tobacco products currently on the market. “Today’s decisions are just the first of many forthcoming product review actions to be issued,” said Mitch Zeller, JD, director of the FDA's Center for Tobacco Products. “The FDA is committed to making science-based decisions on all product applications and providing the agency’s scientific rationale behind its actions to ensure the most transparent and efficient process possible for all involved parties, according to the law.” Read more on tobacco.
Daily Contacts Leave Kids, Teachers, Health Care Workers at Highest Flu Risk
Children, teachers and health care workers are at the greatest risk of catching and transmitting influenza, according to a new study in the journal Proceedings of the Royal Society B. The study utilizes online and mail surveys to analyze the daily social contacts of more than 5,000 people. "People working as teachers or health professionals are no doubt already aware that they have higher risks of picking up bugs like colds and flu. But before this study there was very little data mapping out the contact patterns humans have in their daily life," said Leon Danon, from the Mathematics Institute at the University of Warwick, England, in a release. "By quantifying those social interactions, we can better predict the risks of contracting and spreading infections and ultimately better target epidemic control measures in the case of pandemic flu, for example.” Researchers recommend the people at greatest risk be especially careful to wash their hands with soap and water; maintain clean surfaces; and use tissues when needed.

New Study Paints Larger Picture on Adolescent Concussions
New research on youth concussions gives a broader picture of the “silent epidemic” and shows that kids who smoke and drink are at increased risk. The study appears in the Journal of the American Medical Association. Canadian researchers found that about 20 percent of approximately 9,000 Ontario adolescents who were surveyed had suffered from a concussion. About half were related to sports, but they also found that teens who smoked marijuana or consumed alcohol were at three-to-five times higher risk. "This is the first study I'm aware of that looked at the general population," said Kenneth Podell, co-director of the Methodist Concussion Center at the Methodist Hospital System in Houston. U.S. emergency departments treat about 173,000 adolescents annually for traumatic brain injuries, which includes concussions, according to the U.S. Centers for Disease Control and Prevention.
