America’s kids are safer now than a decade ago when it comes to many types of injury, with two glaring exceptions: drugs and guns. That’s the crux of a new study that looked at injury trends among U.S. children and teenagers between 2011 and 2021. It found that nonfatal injuries from accidents and assaults fell by 55% and 60%, respectively, during that time period. That included substantial drops in injury due to car crashes, falls and other accidents that have long been leading causes of injury among kids. Countering those gains, though, was the harsh reality of guns and drugs. Firearm fatalities among children and teens rose by 87% during the study period, while nonfatal gun injuries more than doubled. Meanwhile, deadly drug overdoses also doubled. “As a society, we’ve done a great job at targeted interventions,” said senior researcher Dr. Rebekah Mannix, of Boston Children’s Hospital. Everything from better car and roadway design, to helmets, to childproof household products have made kids safer in many ways, Mannix said. “But what we’ve missed,” she added, “is that the most lethal means of injury are still incredibly accessible to kids.” The findings, published Oct. 5 in the journal Pediatrics, come at a time when a record number of U.S. kids, mainly older teenagers, are dying from gun-related injuries. In 2020, firearms became the leading cause of…  read on >  read on >

People recovering from wounds or severe burns might one day be treated with fully functional “bioprinted” skin created in a lab, a new study suggests. Researchers say they “printed” skin samples containing all six major human cell types found in skin. The result was multi-layered, full-thickness skin containing all three layers present in normal human tissue: epidermis, dermis and hypodermis. Test transplants performed in the lab found that the bioprinted skin formed blood vessels and skin patterns, essentially functioning and forming as normal human tissue. Other tests demonstrated improved wound closure, reduced skin contraction, and more collagen production to reduce scarring, the researchers reported. The report was published Oct. 4 in the journal Science Translational Medicine. “Comprehensive skin healing is a significant clinical challenge, affecting millions of individuals worldwide, with limited options,” said lead researcher Dr. Anthony Atala, director of the Wake Forest Institute for Regenerative Medicine in North Carolina. “These results show that the creation of full-thickness, human bioengineered skin is possible, and promotes quicker healing and more naturally appearing outcomes,” Atala said in a Wake Forest news release. Perfected skin regeneration could provide burn victims, wounded soldiers and those with skin disorders an opportunity for complete healing. The sort of grafts available today have only some of the elements of normal skin, which can lead to a scarred appearance. The creation of full-thickness…  read on >  read on >

Grandma knew it all along: Certain places on the body are “hot spots” for unhealthy microbes. That notion — which the authors of a new study dubbed “the grandma hypothesis,” after grandma’s admonitions to clean behind the ears — was tested by students in a genomics course at George Washington (GW) University in Washington, D.C. The investigators proved what grandma knew all along: Skin behind the ears and between the toes can harbor unhealthy microbes. The collection of microbes living on and in the body is known the microbiome. It has a role in human health. The skin’s microbiome varies across dry, moist and oily areas. So students set out to test the hypothesis. Keith Crandall, director of the Computational Biology Institute at GW, recalled his own grandmother always telling the kids in his family to “scrub behind the ears, between the toes and in the belly button.” Crandall thought these hot spots were normally washed less often compared to the skin on the arms or legs and might harbor different types of bacteria. Together with Marcos Pérez-Losada, an associate professor of biostatistics and bioinformatics, he designed this genomics course. In it, 129 graduate and undergraduate students were taught to collect their own data by swabbing certain moist and oily hot spots, behind the ears, between the toes and in the naval. They swabbed calves…  read on >  read on >

The risk of falls increases in older age, and along with it, the risk for serious physical or psychological damage, but there are steps people can take to help prevent these accidents. Each year, about 27% of adults 65 and older fall and about 10% of those are injured. “If you’ve experienced a fall or have a fear of falling, you are at a higher risk of falling. Once an older adult falls, they can develop post-fall anxiety syndrome,” said Dr. Angela Catic, associate professor at Baylor College of Medicine’s Center on Aging, in Houston. “It’s important for older populations to remain as independent as possible in their own homes. You can help support this by making sure common falling hazards are not in their homes,” Catic added in a college news release. She offered some tips for improved safety: Stay active but avoid exercises and equipment where seniors cannot be in complete control of their environment. This includes treadmills or other heavy machinery. Work with a physical therapist to determine what kind of exercise is best suited to the individual. Be aware of medications that can cause cognitive impairment. Give up slippers and flipflops in favor of shoes with traction. Make sure lighting is adequate both in and outside the house. Make sure paths inside the home and to bedrooms and living spaces are…  read on >  read on >

Some children who have a common form of eczema should also be tested for allergic reactions because they may have a second allergic-type eczema, a new study suggests. While atopic dermatitis is common and usually develops by age 5, allergic contact dermatitis has similar symptoms and can be triggered by a range of substances. In general, eczema is a group of medical conditions causing inflamed, irritated and itchy skin. In the study, children with atopic dermatitis were more likely to test positive for allergies in patch testing. The findings were published Sept. 26 in the Journal of the American Academy of Dermatology. “When a dermatologist sees a child who looks like they have eczema, we usually think that it’s atopic dermatitis because nearly 1 in 5 children develop it,” said senior study author Dr. JiaDe (Jeff) Yu, an assistant professor of adult and pediatric dermatology at Massachusetts General Hospital. “Sometimes these kids could have allergic contact dermatitis, but the only way to tell is through patch testing, which is designed to identify substances that may be irritating your skin,” he said in a journal news release. Patient Liz Schoeben knows the importance of testing for this allergic-type eczema. Schoeben has had atopic dermatitis since she was 9 and now knows she also has the allergic contact dermatitis. “I remember having it in elementary school off…  read on >  read on >
