The brains of girls and boys who have binge eating disorder show key differences, according to a new study. That’s an important finding, researchers say, because both genders struggle with eating disorders, yet treatments are mainly targeted at girls. “Males have been excluded from research on eating disorders for decades,” said Stuart Murray, an associate professor of psychiatry and behavioral sciences at the University of Southern California’s Keck School of Medicine. He noted that the exclusion stems from the belief that it was uncommon for males to have eating disorders. “As a result of the exclusion of boys and men, we have developed treatments only from studying females, which we then apply to boys and men and hope they work with the same efficacy,” Murray said in a school news release. Some eating disorders are nearly as prevalent among men and boys as in women and girls. Evidence is mounting that eating disorders are diseases of the brain and not the result of social pressure or a lack of willpower, according to researchers. This research team used data from a study of adolescent brain development that included more than 11,800 participants. Researchers identified 38 boys and 33 girls who had a diagnosis of binge eating disorder. In all kids, boys represent about 57% of those with binge eating disorder. Adult males represent about 43% of…  read on >  read on >

The state of California is suing several companies for their role in manufacturing “forever chemicals.” The lawsuit filed Thursday also claims that the companies, including 3M and DuPont, covered up the harm their products, commonly known as PFAS, were causing to the state’s environment and to people. “PFAS are as ubiquitous in California as they are harmful,” State Attorney General Rob Bonta said in a news release. “As a result of a decades-long campaign of deception, PFAS are in our waters, our clothing, our houses and even our bodies,” Bonta said. “The damage caused by 3M, DuPont and other manufacturers of PFAS is nothing short of staggering, and without drastic action, California will be dealing with the harms of these toxic chemicals for generations. Today’s lawsuit is the result of a years-long investigation that found that the manufacturers of PFAS knowingly violated state consumer protection and environmental laws. We won’t let them off the hook for the pernicious damage done to our state.” In addition to 3M and DuPont, the state is suing 16 smaller companies for their work with compounds used in firefighting foam, nonstick frying pans, cleaning sprays, water-repellent sports gear, stain-resistant rugs, cosmetics and more. Both DuPont and 3M responded to the lawsuit. Minnesota-based 3M said in a statement that it “acted responsibly in connection with products containing PFAS and will defend…  read on >  read on >

Only one day after California voters approved allowing a state law banning flavored tobacco products to take effect, a tobacco giant has sued to prevent it. R.J. Reynolds on Wednesday filed a federal lawsuit challenging Proposition 31 and the law originally signed by Gov. Gavin Newsom two years ago. The law would ban the sale of all flavored tobacco and vaping products, and could happen within weeks. “Time and time again, Big Tobacco has attempted to steam roll state efforts to protect our youngest residents from the damaging effects of tobacco use,” California Attorney General Rob Bonta said in a statement. “While we have not yet been formally served with the lawsuit, we look forward to vigorously defending this important law in court.” Reynolds, which makes Newport menthol cigarettes and also owns the vaping brand Vuse, is seeking an injunction of the ballot initiative. But the ban’s supporters cried foul. “This is a corporation that sells deadly products trying desperately to overcome the will of the people of the state of California — manipulating the legal system in an attempt to undo democracy,” Desmond Jenson, a senior lawyer in tobacco control programs at the Public Health Law Center, told the New York Times. Tobacco companies had first turned to the ballot initiative to try to delay the ban and put the issue to a statewide…  read on >  read on >

It’s a potentially deadly issue: Some U.S. school administrators don’t keep life-saving albuterol asthma inhalers on hand because they’re afraid of getting sued for misuse. That’s true even in states like Illinois, where strong “stock albuterol” laws are on the books, researchers say. Kids with asthma don’t always carry their inhalers, and some may not even know they have asthma until they have an attack, experts note. But stock inhaler programs in some states are designed to make sure schools do have an asthma reliever, such as albuterol, on hand in case of emergency. “Stock inhaler laws improve access to asthma reliever inhaler medications in schools for children who experience respiratory symptoms,” said study author Dr. Andrea Pappalardo. She’s assistant professor of medicine and pediatrics at the University of Illinois College of Medicine in Chicago and an American College of Allergy, Asthma, and Immunology (ACAAI) member. “This simple policy solution allows for a fail-safe method to having medicine when a child needs it readily available [and] is critical to keeping our children in class where they belong,” Pappalardo said. As it stands, 16 states (Arizona, Georgia, Illinois, Indiana, Iowa, Kentucky, Missouri, Nebraska, New Hampshire, New Mexico, New York, Ohio, Oklahoma, Texas, Utah, and Virginia) have laws or guidelines in place that aim to increase access to timely asthma treatment for kids when they are in…  read on >  read on >

Despite continued efforts by health advocates and U.S. public health officials, a huge number of middle and high school students are still using addictive tobacco products, most often vaping products. A new study released by two federal agencies on Thursday estimated a total of 3.08 million U.S. middle and high school students using some form of tobacco product within the previous 30 days in 2022. “Commercial tobacco product use continues to threaten the health of our nation’s youth, and disparities in youth tobacco product use persist,” said Deirdre Lawrence Kittner, who directs the Office on Smoking and Health at the U.S. Centers for Disease Control and Prevention. “By addressing the factors that lead to youth tobacco product use and helping youth to quit, we can give our nation’s young people the best opportunity to live their healthiest lives,” she said in a CDC news release. In total, just over 11% of all students in middle and high school now vape or use cigars, cigarettes or some form of tobacco product, according to the new report issued jointly by the CDC and the U.S. Food and Drug Administration. Rates were higher at the high school level, with 16.5% of kids in that age group using a tobacco product. About 4.5% of middle school students used tobacco products. By far the most commonly used tobacco product among…  read on >  read on >

Lead is known to damage young children’s brains, and a new study suggests the effects may still be apparent in old age. Researchers found that among nearly 1,100 older U.S. adults, those who grew up in cities with lead-contaminated drinking water generally scored worse on tests of memory and thinking skills. The findings, experts said, suggest that older adults who were exposed to lead decades ago could be at relatively higher risk of dementia — since their cognitive starting point is typically lower. Lead is a naturally occurring metal that can cause serious health effects if it accumulates in the blood. Children younger than 6 are particularly vulnerable, as lead can damage their developing brains and cause learning or behavioral problems. Yet little has been known about whether early life lead exposure has consequences for the aging brain, said John Robert Warren, a professor at the University of Minnesota who worked on the new study. “You can count on one hand the number of studies,” he said. The new findings — published online Nov. 9 in the journal Science Advances — show only a link between childhood lead exposure and cognition later in life. They do not prove cause and effect. But Warren said there are various ways that childhood exposure could have long-range effects, including indirect means. For example, children with high blood lead…  read on >  read on >

When it comes to pollen allergies, there are not only bad days and bad seasons, experts with the right technology can now break down pollen counts by the hour. Specifically, pollen counts are lower between 4 a.m. and noon, a new study done in Georgia found. They’re higher between 2 p.m. and 9 p.m. While experts have been monitoring pollen levels for many years to better understand them and advise patients, they typically measure counts for a 24-hour period, said lead author Dr. Stanley Fineman, an allergist with Atlanta Allergy and Asthma. For the new study, his team and researchers at Emory University in Atlanta used imaging technology to measure pollen in real time. The investigators found that higher counts seemed to align with rising temperatures. “Now we’ve got some real-time data and can tell patients if they’re allergic and they want to do outdoor activities, they should really do it early in the morning,” Fineman said. The research team monitored hourly pollen levels in three areas of Atlanta for a week in March 2021. They averaged pollen concentrations during the week to reduce day-to-day fluctuations caused by weather changes. Warming trends in the United States due to climate change have caused pollen counts to rise earlier in the year than they used to. Plants tend to release more pollen when the temperature is warmer.…  read on >  read on >
