Seniors battling insomnia are best off picking up some dumbbells or doing some push-ups, a new evidence review suggests. Resistance exercise, activities that make muscles work against an external force, appears to be the best means of improving sleep in older adults, researchers found. “Exercise that strengthens muscles, rather than aerobic or combination exercises, is the most effective way to enhance sleep quality,” concluded the research team led by Dr. Kittiphon Nagaviroj, an associate professor with Ramathibodi Hospital at Mahidol University in Bangkok. However, the review also found that aerobic exercise or a combination of strength, aerobic, balance and flexibility exercises can also be effective against insomnia, researchers reported March 4 in the journal Family Medicine and Community Health. Sleep quality tends to decline with age, and up to 1 in 5 seniors has insomnia, seniors said in background notes. Exercise has been shown to help alleviate insomnia, but it’s not been clear what type of exercise would be most effective, researchers added. For their review, the researchers pooled data from 25 previous clinical trials involving nearly 2,200 people. The studies compared aerobic exercises — cycling, dancing, swimming, brisk walking or gardening — against resistance exercises, researchers said. Resistance exercise could include weightlifting or body-weight training like push-ups or planks. People engaging in resistance exercises had 5.7-point average increase in their sleep quality scores, results…  read on >  read on >

Sight-robbing injuries to the cornea can be repaired using a groundbreaking experimental stem cell treatment, a new study shows. The cornea — the clear outermost layer of the eye — can become irreversibly damaged if injury or disease destroys its ability to regenerate new cells. In this new process, stem cells taken from a person’s healthy eye can be used to rebuild the cornea in their damaged eye, researchers reported March 4 in the journal Nature Communications. The process has proven feasible and safe in 14 patients who were treated and followed for 18 months, early clinical trial results show. The treatment is called cultivated autologous limbal epithelial cells, or CALEC. “Our first trial in four patients showed that CALEC was safe and the treatment was possible,” lead investigator Dr. Ula Jurkunas, associate director of the Cornea Service at Mass Eye and Ear in Boston, said in a news release. “Now we have this new data supporting that CALEC is more than 90% effective at restoring the cornea’s surface, which makes a meaningful difference in individuals with cornea damage that was considered untreatable,” she said. The outer border of the cornea, the limbus, contains many healthy stem cells called limbal epithelial cells, researchers explained in background notes. These cells constantly rebuild the cornea, keeping it clear and smooth. When a person’s cornea is damaged, the…  read on >  read on >

Social media influencers tout the benefits of “cycle syncing” to boost strength training results among women. The idea is that women who lift weights during their period build more muscle, because their bodies are flooded with the female hormone estrogen. But there’s absolutely nothing to this trendy notion, a new small-scale study argues. Researchers found no difference in the body’s response to heavy resistance exercise when performed during different times within the menstrual cycle. “Our findings conflict with the popular notion that there is some kind of hormonal advantage to performing different exercises in each phase,” said lead researcher Lauren Colenso-Semple, who conducted the study as a doctoral candidate at McMaster University in Canada. “We saw no differences, regardless of cycle timing,” she said in a news release. Cycle syncing has been made popular by internet influencers who tout fitness apps that track cycles, researchers said in background notes. These influencers say that women can lead healthier lives by altering their lifestyle — their workouts, diets and other behaviors — to align with their menstrual cycle. For this new study, researchers recruited 12 healthy young women and monitored their menstrual cycles to confirm that their cycles were normal. Contrary to popular belief, very few women — about 12% — have a consistent 28-day cycle and ovulate regularly on day 14 along the lines of the…  read on >  read on >

Bad meetings don’t just waste time — they can leave workers with a “meeting hangover,” new research shows. More than 90% of employees surveyed by the University of North Carolina at Charlotte said they sometimes experience these “hangovers” — lingering frustration and distraction after unproductive meetings. More than half said these “hangovers” hurt their overall productivity. “A meeting hangover is the idea that when we have a bad meeting, we just don’t leave it at the door. It sticks with us and it negatively affects our productivity,” said Steven Rogelberg, a professor of management at UNC- Charlotte and author of “The Surprising Science of Meetings.“ The study found that these bad meetings don’t just affect you, they can also spread negativity across teams. Colleagues also tend to vent to coworkers, sharing their frustrations in a process called “co-rumination” — which can hurt the overall atmosphere and make productivity issues even worse. Factors that can lead to negative experiences include: Meetings that could have been handled by email Unclear or irrelevant agendas Poor facilitation or meetings that run over alloted time No clear decisions made Rogelberg offered CBS several strategies to improve meetings and reduce hangovers. “Keep the attendee list as small as possible,” he said. “Remember that the more the leader talks, the lower the rating of effectiveness. Thus, the meeting leader needs to talk…  read on >  read on >

Race plays a role in whether a child is quickly and accurately diagnosed with asthma, a new study suggests. Outdated and flawed studies previously led to the belief that white children had “naturally higher” lung function compared to other races, researchers said. Diagnostic procedures based on that assumption have caused asthma to be dramatically underdiagnosed among Black children, researchers reported Feb. 28 in JAMA Open Network. About 2.5 to 4 times more Black children with asthma symptoms are diagnosed with reduced lung function when doctors use updated formulas, or equations, that exclude race, researchers found. “These findings have significant clinical implications and further support the universal use of race-neutral equations to increase the likelihood of identifying reduced lung function and improving the detection of asthma, particularly in Black children, promoting health equity,” the research team led by Dr. Gurjit Khurana Hershey, director of asthma research at Cincinnati Children’s Hospital, concluded. Diagnosis of asthma requires lung function testing using a calculation built into U.S. spirometers, researchers said in background notes. This calculation follows a standard formula using age, sex, body size and race. Because of those earlier studies, the racial component of the formula adjusted lung function by 10% to 15% for Black people and 4% to 6% for Asian people, researchers said. In 2022, the Global Lung Initiative Network updated lung function reference equations to…  read on >  read on >

Yelling. Taunts. Insults. Harsh words. Physical violence. About 1 in 5 college athletes receive such abuse from their coaches, researchers report. Overall, nearly 19% of more than 3,300 athletes on National College Athletic Association (NCAA) teams said they’d experienced abusive supervision from their coach. Athletes in team sports and athletes with a disability had significantly higher odds of drawing abuse from their coach, results show. “Overall, athletes rely heavily on their coaches for professional and personal growth,” the research team led by senior investigator Dr. Yetsa Tuakli-Worsornu, founding director of the Stanford University Center for Sports Equity, noted. “The presence of abusive leadership behaviors can hinder this development, as well as negatively affect an athlete’s performance, experience of sport and mental health,” the researchers added. For the study, they analyzed data from the 2021-22 myPlaybook survey administered by the University of North Carolina Greensboro Institute to Promote Athlete Health & Wellness, in collaboration with Stanford University’s Sports Equity Lab. The survey included questions regarding abusive supervision, to which 3,317 student athletes provided responses. Of those, 618 (nearly 19%) said their coaches had been abusive, results show. Athletes participating in a team sport were about 10% more likely to be abused, and those with a disability were 17% more likely, results show. Abuse was not significantly associated with an athlete’s race, gender identity or sexual orientation,…  read on >  read on >

More than half of adults and a third of children and teens worldwide will be overweight or obese by 2050, a comprehensive global analysis has concluded. Overweight and obesity rates in adults, children and teens more than doubled over the past three decades, afflicting 2.1 billion adults and 493 million young people with excess weight, researchers reported in The Lancet. And unless something changes, about 60% of adults (3.8 billion) and a third of children and teens (746 million) will be overweight or obese by 2050, researchers project. “The unprecedented global epidemic of overweight and obesity is a profound tragedy and a monumental societal failure,” lead author Emmanuela Gakidou said in a news release. She’s a professor of health metrics sciences with the Institute for Health Metrics and Evaluation at the University of Washington in Seattle. Among high-income countries, America had the highest rates of obesity, results show. About 42% of men and 46% of women in the U.S. were obese in 2021. More than half of adults with excess weight now live in just eight countries, researchers found: China (402 million), India (180 million), the United States (172 million), Brazil (88 million), Russia (71 million), Mexico (58 million), Indonesia (52 million) and Egypt (41 million). The largest number of adults with overweight and obesity in 2050 are expected to be in China (627 million),…  read on >  read on >

More than a third of food-allergic kids were able to eat full servings of their trigger foods after treatment with an injectable asthma drug, new clinical trial findings report. In all, 36% of children treated with omalizumab (Xolair) for a year successfully ate full servings of allergy-triggering foods, according to phase 2 trial results presented Sunday at a meeting of the American Academy of Allergy, Asthma & Immunology in San Diego. By comparison, only 19% of children could do the same when given a shorter round of omalizumab followed by months of oral immunotherapy, a treatment through which patients build tolerance by eating gradually increasing amounts of food allergens. Further, early stage 3 results from the clinical trial found that children retained some resistance to food allergies even after they stopped taking omalizumab, researchers reported. “This is the first time we’ve been able to directly compare these two treatments for multiple food allergies, and our study shows omalizumab was superior to oral immunotherapy,” principal investigator Dr. Robert Wood, director of the Eudowood Division of Allergy, Immunology and Rheumatology at Johns Hopkins Children’s Center, said in a news release. Food allergies are common, affecting 8% of U.S. children and 10% of adults, researchers said in background notes. Omalizumab works by binding to the antibodies that promote allergic reactions, rendering them inactive, researchers said in background notes.…  read on >  read on >

Suicide prevention campaigns are overlooking seniors, even though people 75 and older have the highest rates of suicide for any age group, a new study says. None of the seven most prominent suicide prevention programs include any messaging aimed at at-risk seniors on their web sites. Older adults are ignored even though five of the programs specifically acknowledge older adults as a high-risk population for suicide on those very web sites, researchers reported Feb. 24 in the American Journal of Geriatric Psychiatry. “Public-facing suicide prevention campaigns have a record of effectiveness, and the need for such campaigns targeting older adults is greater than ever,” senior researcher Dr. Ipsit Vahia, chief of geriatric psychiatry at McLean Hospital in Belmont, Mass., said in a news release. “Our hope is that shedding a light on this imbalance may lead to major suicide prevention organizations considering ways to make their resources more easily accessible to older adults,” he continued. The suicide rate among people 75 and older is 20.3 deaths per 100,000 Americans, and 23 per 100,000 for those 85 and older, according to the U.S. Centers for Disease Control and Prevention. That far outpaces the rates for every other age group: 10-14 years of age (2.4 per 100,000); 15-24 (13.6); 25-34 (19); 35-44 (18.7); 45-54 (19.2); 55-64 (18.7); and 65-74 (16). What’s more, the suicide rate for seniors…  read on >  read on >

As this year’s severe flu season rages across the country, federal health officials are investigating a rise in rare but life-threatening brain complications in children. The U.S. Centers for Disease Control and Prevention (CDC) says at least 19,000 people have died from the flu so far this winter, including 86 children.  New data show that nine of those child deaths involved serious brain complications tied to the flu, the CDC reported Feb. 27 in it’s Morbidity and Mortality Weekly Report (MMWR). The condition, known as influenza-associated encephalopathy or encephalitis (IAE), is a rare type of brain inflammation triggered by the flu. In severe cases, children can develop acute necrotizing encephalopathy (ANE), a dangerous form of brain damage linked to viral infections like flu. While IAE is rare, the CDC’s preliminary data for the 2024-25 flu season link 13% of child flu deaths to these brain complications. Among 1,840 pediatric flu deaths reported to the CDC since 2010, 166 children (9%) had these brain complications.  In some past seasons, the percentage was lower (4% in 2013-14 and 0% in 2020-21 when flu dropped to historic a low during the COVID pandemic). In other seasons, it was as high as 14% (2011-12 season). One challenge for public health experts, The Associated Press reported, is that there’s no official system to track IAE or ANE cases in the…  read on >  read on >
