In today's health news:
A Mississippi baby girl born with HIV, the virus that causes AIDS, has been "functionally cured," doctors announced over the weekend, meaning she only has trace amounts of HIV in her blood and can manage it without the help of medication. The Los Angeles Times says if the treatment can be replicated, it could help reverse the trajectory of the disease for the estimated 1,000 babies born with HIV every day, most of whom are from Africa.
A new poll suggests that people who exercise harder sleep better. U.S. News & World Report says "vigorous exercisers" were twice as likely as their more sedentary counterparts to have had a good night's sleep most nights or every night of the week. More than two-thirds of exercisers also reported having no trouble falling asleep, or going back to sleep if they woke up too early.
People who lived with attention-deficit hyperactivity disorder (ADHD) in childhood may continue to live with the condition as adults, which means, in part, an increased risk for certain psychiatric disorders. Science World Report says 29 percent of children diagnosed with ADHD still had it when they turned 27; additionally, 57 percent who had ADHD as a kid had at least one other psychiatric disorder as an adult, compared to 35 percent of those who didn't have ADHD. Those disorders include antisocial personality disorder, substance abuse problems, anxiety disorder and major depression.
Exposure to the chemical bisphenol A – commonly known as BPA – may be at least partly to blame for rising asthma rates in the U.S., says a new study – which has major implications since BPA is ubiquitous and can be found in items like food packaging, tableware and storage containers. CBSNews.com says researchers found that children who are exposed to "fairly routine, low doses" of BPA have an increased risk of asthma, although exposure isn't a guarantee they'll develop the condition.
Researchers writing in the journal Nature Genetics have identified seven genetic regions associated with age-related macular degeneration, a common cause of blindness among the elderly. Identifying these regions could help researchers develop and target medical treatments for the condition.
And finally: The Hill reports that a panel of experts is recommending that the U.S. abandon its fee-for-service payment model in the health care industry and move to a new system by 2020 in order to cut back on costs and improve the quality of care patients receive.
