FDA Proposes New Rules for Proving Effectiveness, Safety of Antibacterial Soaps
A new proposed rule from the U.S. Food and Drug Administration (FDA) would require manufacturers of antibacterial hand soaps and body washes to prove not only that their products are more effective than normal soap when it comes to preventing illness and infections, but that they are also safe for daily long-term use. Products that can’t meet these standards would need to be reworked before coming to market. The regulatory move comes as research suggests that not only are antibacterial products not helpful, but they could also be harmful in the long term, leading to bacterial resistance and hormonal problems. Hand sanitizers, wipes and other antibacterial products used in health care settings would not fall under the new regulations. “Antibacterial soaps and body washes are used widely and frequently by consumers in everyday home, work, school, and public settings, where the risk of infection is relatively low,” said Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research (CDER). “Due to consumers’ extensive exposure to the ingredients in antibacterial soaps, we believe there should be a clearly demonstrated benefit from using antibacterial soap to balance any potential risk.” Read more on infectious disease.
NIH, NFL to Research Ways to Diagnose, Treat Traumatic Brain Injuries
New research projects from the U.S. National Institutes of Health (NIH) will explore methods to diagnose and treat chronic traumatic encephalopathy, or CTE, in football players and others who experience head injuries and concussions. Current science only allows health care professionals to diagnose the traumatic brain injuries after death. "This is a public health problem," said Walter Koroshetz, deputy director of the NIH's National Institute of Neurological Disorders and Stroke. "We don't know the mechanics of the head injuries that lead to this, the number and severity that is required to get this. We don't know whether certain people based on their genes are more susceptible or not. There are a lot of questions to be answered." The National Football League will cover $12 million of the $14 million in research costs. Earlier this year the league agreed to pay as much as $765 million to former players who accused the league of covering up and downplaying the risks of brain injury. Read more on mental health.
Studies: Multivitamins, Supplements Don’t Improve Overall Wellness
Daily multivitamins and mineral supplements don’t prevent heart problems or memory loss, and are also not linked to longer lives, according to three new studies in the journal Annals of Internal Medicine. The researchers said the findings indicate that U.S. consumers should stop taking the dietary supplements, which are part of a multibillion-dollar U.S. industry. "We believe that it's clear that vitamins are not working," said Eliseo Guallar, MD, a professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health, adding “"The probability of a meaningful effect is so small that it's not worth doing study after study and spending research dollars on these questions."
