An alarming new survey shows that American teen girls are experiencing record high levels of violence, sadness and suicide risk. Schools may be the answer to improving what’s happening for young people, according to the report from the U.S. Centers for Disease Control and Prevention. About 3 in 5 girls — 57% — said they felt persistently sad or hopeless in 2021. That’s up 60%, the CDC reported, and those numbers are double the number of teen boys experiencing sadness or hopelessness. Girls fared worse than boys across nearly all measures, though all teens reported increasing mental health challenges, experiences of violence and suicidal thoughts and behaviors. LGBTQ teens also continued to experience extremely high levels of violence and mental health concerns. “High school should be a time for trailblazing, not trauma. These data show our kids need far more support to cope, hope, and thrive,” said Dr. Debra Houry, the CDC’s Chief Medical Officer and Deputy Director for Program and Science. “Proven school prevention programs can offer teens a vital lifeline in these growing waves of trauma,” she said in an agency news release. According to the Youth Risk Behavior Survey (YRBS), 30% of teen girls seriously considered attempting suicide. About 18% experienced sexual violence in the past year, up 20% from 2017, when the CDC started monitoring this measure. About 14% had ever…  read on >  read on >

Often, patients with nonalcoholic fatty liver disease are advised to lose weight, but that can be hard to do and takes precious time. Now, researchers report they have found another strategy can help lower liver fat in people with this condition, which affects nearly 30% of the global population. Exercise of about 150 minutes each week at a moderate intensity — the exact recommendation from public health experts at the U.S. Department of Health and Human Services — significantly reduced liver fat in patients, the new meta-analysis showed. “I spend a lot of my time trying to help improve the lives of our patients with nonalcoholic fatty liver disease [NAFLD],” said Dr. Jonathan Stine. He is an associate professor of medicine and public health sciences and a hepatologist at Penn State Health Milton S. Hershey Medical Center, in Hershey, Pa. “At this point in time, we still don’t have a regulatory agency-approved drug therapy or even a cure for this condition. And there are roughly a hundred million adults in this country that have this,” Stine noted. While research had shown that exercise can improve liver fat, physical fitness, body composition and quality of life, there was no known specific amount of exercise that would do this. For this study, the researchers considered a 30% relative reduction in liver fat — measured by MRI scans…  read on >  read on >

Exposure to wildfire smoke can increase the risk of premature birth, new research suggests. For the study, the researchers reviewed birth certificates and hospital delivery data for more than 2.5 million pregnant women in California from 2007 to 2012, and used satellite images and ZIP codes to compare daily estimates of wildfire smoke intensity. The study found that from the four weeks prior to conception and through the first 20 weeks of pregnancy, 86% of the women were exposed to at least one day of wildfire smoke. They had an average exposure of 7.5 days. Wildfire smoke was significantly associated with spontaneous preterm birth, the investigators found. Each additional day of smoke exposure slightly increased the odds of delivering prematurely. “Wildfires lead to acute and abrupt changes in air quality,” said lead study author Dr. Anne Waldrop, a maternal-fetal medicine subspecialist fellow at Stanford University in Palo Alto, Calif. “And some emerging evidence suggests that wildfire smoke could be worse for your health than other types of pollutants. So, even as we work to decrease other forms of air pollution, with wildfires becoming more frequent, more intense, and happening on a much larger scale, exposure to wildfire smoke is a serious public health problem, especially for vulnerable populations like pregnant people,” Waldrop said in a news release from the Society for Maternal-Fetal Medicine. Wildfire smoke…  read on >  read on >

Researchers studying well water found current monitoring practices often fail to reflect actual groundwater pollution risks. The problem: Spikes in harmful bacteria, like those from animal and human waste, vary depending on the season. They may be higher at times when testing is less likely to be done. “This is concerning because many residents and homeowners across the country, including here in the Northeast, have been found to test their wells in colder months, which can cause a false sense of security and underestimate the true threat of harmful bacteria in their drinking water,” said study co-author Ranjit Bawa, a visiting assistant professor of natural resources and the environment at the University of New Hampshire in Durham. The research team studied this by looking at year-round water samples from nearly 50,000 wells across the state of North Carolina between 2013 and 2018. The investigators found a significant gap in the timing of sample collection from private wells and when they were likely to become contaminated. More than 44 million people in the United States depend on private drinking water wells. These wells are not federally regulated, the study authors noted in a university news release. Communities without access to public water systems also tend to be near sources of industrial and agricultural pollution, according to the report. The researchers focused on wells near hog farm…  read on >  read on >

Canned tuna is known to contain low levels of mercury, but a new Consumer Reports investigation has found spikes of the neurotoxin in some cans. The organization tested five popular tuna brands, CBS News reported. While the mercury levels were all within U.S. Food and Drug Administration standards, Consumer Reports urged pregnant women to “avoid canned tuna altogether.” FDA guidelines say pregnant women can eat canned tuna in limited quantities. “While canned tuna, especially light varieties, has relatively low average levels of mercury, individual cans can sometimes have much higher levels,” Consumer Reports said. “From can to can, mercury levels can spike in unpredictable ways that might jeopardize the health of a fetus,” said James Rogers, director of food safety research and testing at the independent nonprofit. Mercury can affect neurodevelopment, said CBS News medical contributor Dr. David Agus. The effects may include impaired brain function and developmental delays in children. If a fetus is exposed to high levels of mercury, it may lead to thinking and memory issues later on, he said. “Young children and pregnant women especially need to keep mercury away from those neurons that are developing,” Agus told CBS News. Consumer Reports tested 10 tuna products from five brands: Bumble Bee, Chicken of the Sea, Safe Catch, StarKist and Wild Planet. The tests included about 30 samples of both albacore and…  read on >  read on >

Healthy young people who vape or smoke may be putting themselves at greater risk for developing severe COVID, new research finds. Both smoking tobacco and vaping electronic cigarettes may predispose people to increased inflammation, future development of severe COVID-19 and lingering cardiovascular complications, said lead study author Dr. Theodoros Kelesidis. He’s an associate professor of medicine in the division of infectious diseases at UCLA’s David Geffen School of Medicine, in Los Angeles. “The key message is that smoking is the worst, but vaping is not innocent,” Kelesidis said in a UCLA news release. “This has been shown for many lung diseases, but not for COVID. It was a quite interesting and novel finding that vaping changed the levels of key proteins that the virus uses to replicate.” For the study, the researchers examined blood plasma collected before the pandemic from 45 nonsmokers, 30 vapers and 29 cigarette smokers. The investigators tested the plasma to measure levels of since-identified proteins that the COVID virus needs in order to replicate. These proteins are known as ACE2, furin, Ang II, Ang 1–7, IL-6R, sCD163 and L-selectin. A protein called ADAM17 collectively regulates those last three proteins. The researchers found that plasma from healthy young people who smoke tobacco or vape had increased levels of furin, sCD163, and L-selectin, compared to nonsmokers. The findings suggest there may be increased…  read on >  read on >

Using a “neuroprotectant” drug alongside the standard surgical removal of a clot may slash the risk of death and disability following a stroke, a new study finds. The new medication, called ApTOLL, shields brain tissue from continuing damage by cooling down inflammation, the researchers said. A stroke occurs when blood supply to part of the brain is blocked by a clot or when a blood vessel in the brain bursts. Ischemic strokes, which are far more common, occur when a blood clot cuts off blood supply to the brain. Still, more research is needed before ApTOLL is ready for prime time. “We need confirmatory studies in larger populations, and we are aiming to start those in the last quarter of 2023,” said study author Dr. Marc Ribó, an interventional neurologist at Hospital Vall d’Hebron in Barcelona, Spain. “If everything goes well and we replicate these findings in larger studies, the drug may be available in a couple of years.” For the study, more than 150 people who had an ischemic stroke (average age, 70) were treated in 15 hospitals in France and Spain between July 2021 and April 2022. Patients received either 0.05 mg/kg of ApTOLL, 0.2 mg/kg of ApTOLL, or a placebo medication. Everyone in the study also underwent mechanical blood clot removal to restore blood flow to their brain within six hours of…  read on >  read on >

Chemicals found in plastic personal care products, kids’ toys, and food and drink packaging could be raising the risk of type 2 diabetes among women, new research suggests. To study the impact of these chemicals, known as phthalates, researchers followed just over 1,300 U.S. women for six years to see if exposure contributed to the incidence of diabetes. About 5% of the women developed diabetes during the study period. The researchers found that white women exposed to high levels of some phthalates had a 30% to 63% higher chance of developing diabetes. The harmful chemicals were not linked to diabetes risk in Black or Asian women. Exposure to these endocrine-disrupting chemicals has previously been associated with reduced fertility and other endocrine disorders. “Our research found phthalates may contribute to a higher incidence of diabetes in women, especially white women, over a six-year period,” said Sung Kyun Park, an associate professor of epidemiology and environmental health sciences at the University of Michigan School of Public Health, in Ann Arbor. “People are exposed to phthalates daily, increasing their risk of several metabolic diseases. It’s important that we address [endocrine-disrupting chemicals] now as they are harmful to human health,” Park said in a news release from the Endocrine Society. The study, which was published online Feb. 8 in the Journal of Clinical Endocrinology & Metabolism, received funding from…  read on >  read on >

Parents in the United States may assume baby food is free of impurities, but a recent research review highlights the much different reality: Most foods made for babies and toddlers have some amount of toxic heavy metals. The contaminants include metals, such as lead and arsenic, that can harm brain development, and contribute to learning and behavior problems in children. And they are found in everything from rice cereals to formula to pureed vegetables. It’s an issue that’s been known for decades, yet most parents are probably unaware of it, experts said. “Most people would probably think that, out of all foods, baby food has to be the safest,” said Dr. Sarah Ventre, the lead author on the review and a pediatrician at the University at Buffalo, in New York. But lead, arsenic and other toxic metals exist in the soil and groundwater, finding their way into the food supply, including the products that ultimately end up in baby food. A 2019 study found heavy metals in 95% of baby foods tested. One-quarter contained traces of all four metals researchers assessed: arsenic, cadmium, lead and mercury. That study was commissioned by the nonprofit Healthy Babies Bright Futures (HBBF), and included in the new review. Jane Houlihan, research director at HBBF, agreed that the facts surprise parents, who may assume baby food is tightly regulated. “But…  read on >  read on >

There’s been plenty of scientific debate about whether vaping is safer than tobacco, and whether it may help some people stop smoking. According to a recent Cochrane Review analysis of 78 studies, electronic cigarettes show more success in helping people quit smoking than traditional nicotine-replacement therapies, such as nicotine patches and gums. “The most important finding from our recent review update is that for the first time there is high certainty evidence that nicotine e-cigarettes are more effective than traditional nicotine-replacement therapies, such as patches, gum or lozenges, in helping people to quit smoking,” said study co-author Ailsa Butler. She is a postdoctoral researcher from the University of Oxford’s Centre for Evidence-Based Medicine, in the United Kingdom. But is vaping better than smoking? Let’s look at how vaping compares to smoking in terms of its safety and effects on your health. How vaping works Vapes, or e-cigarettes, are handheld devices that contain a reservoir for liquid, according to the U.S. National Institutes of Health. This liquid is vaporized upon heating. The heating element is usually powered by a battery. The liquid that goes into the reservoir or “pod” comes in both nicotine and nicotine-free forms. While the liquid may be free of harsh chemicals, it may contain carcinogens or other toxins that can be harmful to your health, according to the National Institute on Drug…  read on >  read on >
