Three out of five young people who die by suicide don’t have any prior mental health diagnosis, a new study finds. People are missing the telltale signs that children, teens and young adults are troubled in ways that put them at risk for suicide, researchers said. “Our findings point to the critical need to increase equitable access to mental health screening, diagnosis and treatment for all youth,” said researcher Dr. Jennifer Hoffman, an emergency medicine physician with the Children’s Hospital of Chicago. The results also emphasize the need for safe gun storage, given how impulsive young people can be. There had been no signs of mental troubles in 2 of 3 suicides involving a gun, the most common method among young people in this study, researchers found. An estimated 22.6 million U.S. children live in households with firearms, and 4.5 million live in homes where guns are put away loaded in unlocked drawers and cabinets, researchers said. “To reduce the risk of youth suicide by firearms, counseling is needed to encourage parents to store firearms in the home safely. These messages should be delivered in community and school settings, in addition to doctors’ offices,” Hoffmann said in a hospital news release. “Secure storage laws, also known as child-access prevention laws, have also been demonstrated to reduce firearm suicide rates, and more states need to enact…  read on >  read on >

Smokers with diabetes or obesity who take semaglutide (Ozempic/Wegovy) might reap an added benefit: Help in quitting smoking. A yearlong study found that, compared to people using other diabetes drugs, fewer patients who were taking semaglutide sought out medical help to quit smoking. That suggests the drug might have already been helping them to quit, researchers noted. The finding wasn’t a complete surprise to researchers at the National Institute on Drug Abuse (NIDA), since “clinical anecdotes that patients treated with semaglutide … [have] reported reduced desire to smoke” have already been widespread, they said. The new study was published July 29 in the Annals of Internal Medicine. How might semaglutide cut down on smoking? The researchers noted these drugs (along with Mounjaro and Zepbound) are glucagon-like peptide receptor agonists (GLP-1s), which work to suppress appetite by targeting specific receptors in the brain. Studies in mice have shown that GLP-1s also reduce “nicotine-induced increases in dopamine release” in a specific brain area, “a common mechanism underlying the rewarding effects of addictive drugs,” the researchers explained. The new study was led by NIDA director Dr. Nora Volkow. Her team analyzed data from seven trials, all involving smokers who also had type 2 diabetes. Almost 223,000 patients were tracked for a year, and they took a variety of diabetes meds, including insulin, metformin and sulfonylureas, among others. A…  read on >  read on >

Doctors might be authority figures, but a new review suggests hospital patients feel more comfortable when their physician comes across as less imposing. Getting to a patient’s eye level while talking about their diagnosis or care makes a huge difference, researchers found. Sitting or crouching next to a patient’s bedside prompted more feelings of trust and satisfaction, and even helped patients recover better, according to results published recently in the Journal of General Internal Medicine. “We hope our work will bring more recognition to the significance of sitting and the general conclusion that patients appreciate it,” said lead researcher Dr. Nathan Houchens, an associate professor of medicine with the University of Michigan School of Medicine. For the review, researchers analyzed results from 14 previous studies on the impact of a doctor’s posture when they’re at a patient’s bedside. One study found that half of patients preferred talking to a sitting physician, while only 17% liked it when their doctor stood during a consultation. Other studies indicated that medical professionals who sit with a patient prompt more positive impressions than those who stand. For example, nurses who sat at bedside for three to five minutes at the start of each shift wound up improving patients’ perceptions of their communications. Likewise, seated doctors had more patients who said the doctor “always” listens carefully to them and explains…  read on >  read on >

Losing someone close to you can make you age faster, a new study finds. People who lost a parent, partner, sibling or child showed signs of older biological age compared with those who hadn’t experienced such a loss, researchers reported July 29 in the journal JAMA Network Open. “Our study shows strong links between losing loved ones across the life course from childhood to adulthood and faster biological aging in the U.S.,” said lead researcher Allison Aiello, a professor of health longevity with the Columbia University Mailman School of Public Health, in New York City. Biological aging involves the gradual decline in how well your cells, tissues and organs function. Scientists measure this type of aging using DNA markers known as epigenetic clocks, and they can compare it against a person’s calendar age to see how much different factors cause premature aging. For this study, researchers analyzed data on nearly 4,500 people who provided blood samples for DNA testing as part of a long-term study on health. The participants were tracked from their teenage years into adulthood. Researchers tracked deaths among people close to the participants, to see how these losses might relate to their biological age. People who had experienced two or more losses during their lifetime had older biological ages, based on epigenetic testing, researcher found. Further, two or more losses in adulthood…  read on >  read on >

A new test gauging levels of key proteins in the blood was far more accurate than doctor assessments in spotting Alzheimer’s disease in people with early-stage illness. The test, called APS2 (the amyloid probability score 2), was 91% accurate in diagnosing Alzheimer’s in people with mild cognitive decline or early dementia, compared to the 61% success rate of primary care doctors who examined the same patients. The test isn’t yet approved for routine use. But Dr Teresa D’Amato, director of geriatric emergency medicine at Northwell Health in Forest Hills, NY, called the new data “very exciting.” “This blood test would be great as a first round of diagnostic testing because it it looks like it’s pretty accurate,” said D’Amato, who wasn’t involved in the new study. The findings were published July 28 in the Journal of the American Medical Association. They were published simultaneously at the Alzheimer’s Association International Conference in Philapdelphia. An accurate, easily administered blood test for Alzheimer’s could be a game-changer, according to a team of dementia experts who wrote an editorial accompanying the research. “Diagnosing Alzheimer’s is challenging, especially in primary care. Having a reliable blood test is essential to help primary care physicians make an early and accurate diagnosis,” the editorialists said. They included Dr. Stephen Salloway, of Brown University, Dr. Christopher Rowe, of the University of Melbourne, Australia, and…  read on >  read on >

Peak asthma month is upon parents as summer draws to a close, experts warn. “September is known as Asthma Peak Month because kids have returned to school, and viruses are being passed around,” said allergist Dr. Gailen Marshall, president of the American College of Allergy, Asthma and Immunology. “September also sees higher levels of environmental allergens like mold and ragweed. In addition, children may have stopped their regular asthma management routine over the summer,” Marshall added in a ACAAI news release. “Generally, allergists see an increase in patients in September — more asthma attacks and more hospitalizations — especially in children.” But there are ways parents can help their kids keep their allergy and asthma symptoms at bay as the school year resumes, Marshall said. Find an allergist. A pre-school appointment with a board-certified allergist can arm parents with an allergy or asthma action plan that identifies triggers and prepares prescriptions. Asthmatic kids under the care of an allergist have a 77% reduction in lost time from school, Marshall said. Teamwork helps. It’s important to work with a child’s teacher regarding their allergies and asthma, Marshall said. Most teachers have experience helping kids with asthma. Parents should be sure to share their child’s treatment plan with school staff, including their asthma triggers and any treatments or medications they use. Avoid viruses. Respiratory viruses like the…  read on >  read on >

Wildfires raging in several states and Canada are triggering air quality alerts and evacuation orders across the western parts of the United States. Smoke and haze have filled the skies in California, Oregon, Arizona, Washington and several other western states: As of Wednesday, there were 79 large, active wildfires that have burned over 1.4 million acres across the country, according to the National Interagency Fire Center. Evacuation orders are in effect for 15 fires in the Northwest, the Associated Press reported. Meanwhile, Canada is battling about 430 active wildfires in British Columbia and 177 in neighboring Alberta, including two that led to the evacuation of up to 25,000 visitors and residents of the Canadian Rockies’ largest national park, the AP reported. To deal with the pollution spewing from these wildfires, air quality alerts and advisories have been issued in many parts of the western United States: The Oregon Department of Environmental Quality issued air quality alerts for the eastern counties of Harney, Malheur, Grant, Baker and Morrow until further notice. In Idaho, air quality advisories were sent out to the central counties of Ada, Canyon, Gem, Owyhee, Payette and Washington. In north central Washington, the Colville Reservation, all of Chelan County, plus the Methow Valley down to Brewster in Okanogan County were under air quality alerts until further notice. Last but not least, Canadian authorities issued an air quality advisory for…  read on >  read on >

Obese kids infected with dengue are significantly more likely to suffer severe illness requiring hospitalization, a new study warns. A new analysis of nearly 5,000 dengue-infected Sri Lankan children found that weight plays a powerful role in how sick the mosquito-borne virus can make a kid. Kids with higher BMIs had higher hospitalization rates than those children who weighed less, researchers reported recently in the journal PLOS Neglected Tropical Diseases. The heaviest children — those who are clinically obese — were twice as likely to be hospitalized as the rest, results show. “With the increase in obesity in many countries, it would be important to create awareness and educate the public of the potential risks regarding obesity and risk of severe disease and hospitalization from dengue,” said senior researcher Dr. Neelika Malavige, a professor of immunology and molecular medicine at the University of Sri Jayewardenepura in Sri Lanka. The study comes weeks after health officials in the Florida Keys issued a dengue alert following two confirmed cases of the infectious disease there, and the U.S. Centers for Disease Control and Prevention has issued a nationwide advisory about an increased risk of dengue infections in the U.S. Dengue reached a historic high of more than 6.5 million cases and more than 7,300 deaths worldwide in 2023, researchers said in background notes. And the world is about…  read on >  read on >
