Social media presents a “profound risk” to young brains, U.S. Surgeon General Dr. Vivek Murthy warned on Tuesday. In a report, Murthy warned about the risks of social media use for young people and called on policymakers, tech companies, researchers and parents to “urgently take action.” “There are ample indicators that social media can also have a profound risk of harm to the mental health and well-being of children and adolescents,” Murthy said. The full effect of social media isn’t well understood, he noted. “Adolescents are not just smaller adults,” Murthy told The New York Times. “They’re in a different phase of development, and they’re in a critical phase of brain development.” Among the concerns are that if kids are using social media frequently they may actually be altering their developing brains, specifically in the amygdala and the prefrontal cortex. These are important for emotional learning, emotional regulation, impulse control and social behavior. This “could increase sensitivity to social rewards and punishments,” the report stated. Reaction to the report was enthusiastic. “Today’s children and teens do not know a world without digital technology, but the digital world wasn’t built with children’s healthy mental development in mind. We need an approach to help children both on and offline that meets each child where they are while also working to make the digital spaces they inhabit safer…  read on >  read on >

About 7 in 10 American parents are concerned that social media trends related to appearance and editing apps and filters are harming their children’s body image, a new survey shows. Among those polled, about 69% of parents expressed worry about these editing apps and filters, which can completely change the look of someone’s face and body. This may make them appear to meet some supposed standard of beauty. Also, about two-thirds said that trends related to diet and exercise also had a negative influence, according to the survey results released May 23 by the On Our Sleeves Movement for Children’s Mental Health, from Nationwide Children’s Hospital in Columbus, Ohio. A young person’s feelings about their body can affect their mental health, said Erin McTiernan, a contributor to On Our Sleeves and a pediatric psychologist at Nationwide Children’s. “Those concerns are valid,” McTiernan said about parents’ strong response to the survey questions. “Social media has some great benefits for kids, especially in the areas of entertainment and social connection. But when it comes to body image, there are some things that we know can have a negative impact.” Making comparisons Children may compare themselves to these unrealistic standards or feel this is how they should be because of the numbers of “likes” they get on social media for a certain look, McTiernan said. “We know that…  read on >  read on >

For people who survive gunshot wounds, the trauma may leave mental scars that worsen with time, a new study finds. Among 87 adults treated for gun injuries at a Wisconsin trauma center, many had worsening symptoms of post-traumatic stress disorder (PTSD) and depression six months later. The findings, published May 22 in the Annals of Internal Medicine, come from one of the few studies that has tracked the long-term mental health of gunshot victims. For years, gun violence research was stymied in the United States after Congress suspended federal funding for it in 1996. That changed just a few years ago. “For a long time, we weren’t able to do firearms research, so we don’t really know a lot about these long-term outcomes,” said Dr. Peter Ehrlich, director of the pediatric trauma center at the University of Michigan’s C.S. Mott Children’s Hospital. Ehrlich, who was not involved in the new research, published a study last year that looked at the mental health of U.S. children and teenagers who’d sustained gun injuries — and the findings were similar. Of 1,450 kids injured by guns, 35% were newly diagnosed with a mental health condition in the year afterward — most often PTSD or substance abuse. That compared with 26% of U.S. kids who were injured in a motor vehicle crash. Ehrlich said that while the new study…  read on >  read on >

A subset of people may be at high risk for both psychiatric disorders and for using marijuana, based on their genetics, according to a new study. Researchers from the University of Oslo in Norway have found that some of the genetic variants associated with cannabis use are also linked to psychiatric disorders. “These findings are important as they show that the complex links between cannabis use and these disorders may not only be caused by cannabis use itself, but could also be driven by shared genetic susceptibility,” lead co-author Nadine Parker said in a university news release. The rate of cannabis use is high among patients with disorders linked to psychosis, including schizophrenia and bipolar disorder. Cannabis is a psychoactive drug that can sometimes produces psychotic-like symptoms, according to the study. “This study shows that there is a shared genetic basis underlying our susceptibility to both cannabis use and certain psychiatric disorders,” lead co-author Weiqiu Cheng said in the release. To study this, Parker, Cheng and their colleagues used advanced statistical modeling. They found that a majority of shared variants increased the risk of both cannabis use and developing either schizophrenia or bipolar disorder. Yet, there were some genetic variants with opposing effects that increased the risk of cannabis use while decreasing the risk of the two psychiatric disorders. In some parts of the world,…  read on >  read on >

A new study finds that while hydrocortisone on its own may not prevent death from sepsis, it can improve survival when combined with other steroids while eliminating the need for vasopressor drugs. Vasopressor medications help raise blood pressure when it’s so low that you can’t get enough blood to your organs. Doctor often deliver these drugs via an IV. “For the first time, the effects of hydrocortisone for the treatment of patients with septic shock could be studied by analyzing individual data from the main randomized trials published to date,” said researcher Dr. Romain Pirracchio, a professor of anesthesia at University of California, San Francisco (UCSF). “This study shows that if the effect of hydrocortisone on the mortality of septic shock is modest, this treatment makes it possible to spare the exposure of patients to vasopressor drugs and to prevent their complications,” he added in a UCSF news release. “The combination of fludrocortisone with hydrocortisone seems to provide a greater benefit in terms of survival.” Sepsis is the body’s extreme response to infection, according to the U.S. Centers for Disease Control and Prevention. It affects about 55 million people worldwide and causes 11 million deaths each year. Treatment can include recognizing it quickly, controlling the source of the infection, antibiotics, fluids, vasopressors and other therapies. Corticosteroids have been one of these therapies for septic shock…  read on >  read on >

Obese people might be wise to slim down before undergoing an ablation procedure to treat an abnormal heart rhythm, researchers report. Folks with atrial fibrillation who lost 3% or more of their body weight before undergoing ablation had greater odds of their heart returning to a normal rhythm than those who didn’t, a new study finds. A-fib, as atrial fibrillation is called, is an abnormal heartbeat that causes the heart to beat faster and out of sequence. A-fib can cause blood clots that can result in a stroke. To control a-fib, doctors prescribe medication or a procedure called catheter ablation. Ablation uses heat to kill heart cells that are causing the abnormality. The goal is to return the heart to its normal sinus rhythm. “Weight loss is a key factor in the management of atrial fibrillation for those that are overweight or obese,” said lead researcher Dr. Jeffrey Goldberger, a professor of medicine and director of the Center for Atrial Fibrillation at the University of Miami School of Medicine. Obesity is not only a risk factor for a-fib, but appears to also have an effect on treatment, he said. “Obesity is known to be a pro-inflammatory condition,” he said. “It turns out that there’s fat tissue that sits directly on the heart muscle and these fat cells can secrete all sorts of hormones that could…  read on >  read on >

It’s a social media darling and one of the hottest prescription medications on the U.S. market. But does Wegovy really help patients lose weight? Yes, a new study suggests. Investigators analyzed data on more than 100 people using Wegovy (semaglutide). They found that after a year participants had shed more than 13% of their body weight on average. “This medication showed superior weight-loss outcome to all previously approved anti-obesity medications that were tested,” said study lead author Dr. Wissam Ghusn, a research fellow in gastroenterology and hepatology with the Precision Medicine for Obesity Program at the Mayo Clinic in Rochester, Minn. Semaglutide was approved by the U.S. Food and Drug Administration in 2017 to help control blood sugar levels and reduce the risk for heart attacks, stroke and death among patients with type 2 diabetes. For this purpose, the once-weekly injectable medication — sold under the brand name Ozempic — helps the body make more insulin, which lowers blood sugar levels for people with diabetes. But the drug was also associated with weight loss, and the FDA approved it for that purpose in 2021. Sold as Wegovy, the self-administered injectable is given at a higher once-a-week dosage of 2.4 mg. It is intended as a weight-loss medication for adults with an “overweight” body mass index (BMI) between 27 and 29 who also struggle with at…  read on >  read on >

(HealthDay News) – Two western U.S. states issued air quality alerts over the weekend as heavy smoke from fires blazing in Canada drifted south. Both Colorado and Montana experienced air quality issues because of dozens of Canadian fires. A third state, Utah, noted that it was beginning to see smoke, while Idaho had experienced haze last week, the Associated Press reported. “People with heart or lung disease, older adults and children should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion,” Colorado’s Department of Public Health and Environment said in its alert. It issued air quality alerts and advisories for the eastern part of the state, including Denver. Air quality is considered unhealthy for sensitive groups when particle pollution is between 151 and 200. Parts of Colorado’s Front Range were at 168 on Saturday, the AP reported. In the province of Alberta, Canada, fires have led to the evacuation of thousands of residents. The health impact was “very high risk” on Saturday in the cities of Calgary and Edmonton, the AP reported. The smoke in Montana was mostly in the central and eastern parts of the state. In its alert, the Montana Department of Environmental Quality advised residents to avoid outdoor exertion if they could see haze or smoke.

The Atlantic hurricane season in the United States starts June 1, and some dangers might not be immediately obvious: carbon monoxide poisoning, fires and electric shock. “Hurricanes and major storms in the U.S. have increased in frequency and severity in recent years. This hurricane season may bring widespread destruction that could impact millions of Americans,” said Alex Hoehn-Saric, chair of the U.S. Consumer Product Safety Commission. “I urge consumers to follow CPSC’s safety tips to prepare ahead of storms to prevent loss of life in a storm’s aftermath,” he said in a commission news release. Carbon monoxide (CO) from gasoline-powered portable generators can kill within minutes if used improperly. It has no color or odor, so can render a person unconscious even before they recognize the symptoms of nausea, dizziness or weakness, the CPSC warns. This gas kills nearly 100 Americans using portable generators each year. Black individuals have a higher risk of death, accounting for 23% of those who died between 2011 and 2021, according to the CPSC. To stay safe, the commission advises following these recommendations: Never operate a portable generator inside a home, garage, basement, crawl space or shed. It’s not enough to open doors or windows. Lethal levels of CO can still build up. Use these generators outside only, at least 20 feet away from the house. Direct the exhaust away…  read on >  read on >

It’s well known that it’s unhealthy to have belly fat accumulating around your abdominal organs, but there’s a more insidious form of fat that could be even more hazardous to your health, a new study says. Fat that infiltrates your muscles appears to dramatically increase your risk of death, according to findings published May 16 in the journal Radiology. Fatty muscle — a condition called myosteatosis — was associated with a 15.5% increase in absolute risk of death in a group of healthy adults, researchers found. By comparison, obesity appeared to increase participants’ absolute mortality risk by only 7.6%, results show. Fatty liver disease raised risk by 8.5% and muscle wasting by 9.7%. “The signal [for muscle fat risk] was so much stronger for this otherwise healthy cohort,” said senior researcher Dr. Perry Pickhardt, chief of gastrointestinal imaging at the University of Wisconsin School of Medicine and Public Health. “It really stood out as a strong biomarker beyond the things I think we all accept as important measures. “I think there’s going to be profiling of patients where if you line up myosteatosis with a very fatty liver or maybe abundant visceral fat, you might be a lot worse off than if you just had one of those or two of those,” Pickhardt added. Muscle fat has been a subject of increasing interest in the…  read on >  read on >
