The key to weight loss could come down to a combination of 14 “skinny genes,” a recent study says. People with these genes dropped twice as much weight through regular exercise compared to those without the genes, researchers found. Those with the most of these genetic markers lost up to 11 pounds following eight weeks of running, compared to a little more than 4 pounds for those who didn’t get the same genetic boost. “This study highlighted some important genes associated with taking inches off the jeans, but it’s important to remember that the genes will do nothing without exercise and lifestyle changes as they are all interlinked,” lead researcher Henry Chung, a lecturer with the University of Essex School of Sport, Rehabilitation and Exercise Sciences in the U.K., said in a news release.  “Without intervention, they won’t show their true potential and then it doesn’t matter what genes you have,” he continued. For the study, researchers recruited 38 people ages 20 to 40. About half were asked to run 20 to 30 minutes three times a week, while maintaining all their usual diet and lifestyle habits. The rest served as a control group. Results show that one specific gene, called PPARCG1A, was most key to weight loss. The gene is involved in energy metabolism and was present in participants who lost the most weight,…  read on >  read on >

The Fisher-Price company is recalling more than 2 million of its Snuga infant swings, after the suffocation and deaths of five infants who went to sleep while in the swings. “The swing should never be used for sleep and bedding materials should never be added to it,” according to an alert from the U.S. Consumer Product Safety Commission, which announced the recall.  “If the product is used for sleep or bedding material is added, the headrest and body support insert on the seat pad can increase the risk of suffocation,” the agency explained. The CPSC’s advice to parents who already have one of the Snuga infant swings at home: “Consumers should immediately remove both the headrest (by cutting the tether) and the body support insert from the seat pad before continuing to use the swing for awake-time activities.” A full list of the 21 recalled Fisher-Price infant swing models, with photos, can be found at the CPSC. As the agency explained, five reported deaths of infants between one and three months of age were linked to use of Snuga swings between 2012 and 2022. “In most of those incidents, the infants were unrestrained and bedding materials were added to the product,” the CPSC noted. Besides the danger from the Fisher-Price products under recall, the agency reminded parents and caregivers that they “should never use any…  read on >  read on >

Microscopic magnetic nanodiscs could provide a much less invasive means of providing deep brain stimulation, a new study says. The tiny discs – about 250 nanometers across, or 1/500 the width of a human hair – would be injected directly into specific regions of a person’s brain, researchers say. From there, researchers said, the discs could be activated by applying a magnetic field outside the patient’s body. Tests in lab mice show that the discs “had an impact on neuron activity and on behavior,” researcher Ye Ji Kim, a doctoral student at MIT, said in a news release. Deep brain stimulation uses electrodes implanted in target brain regions to treat conditions like Parkinson’s disease, epilepsy, obsessive-compulsive disorder, tremors and Tourette syndrome, the Mayo Clinic says. But placing the implants involves major brain surgery, which opens patients up to a number of harmful complications, researchers noted. These nanodiscs could provide a less invasive alternative to currently used electrodes, researchers said. The nanodiscs contain a magnetic core and an electrically charged outer shell. When exposed to a magnet, the core presses against the outer shell and causes it to deliver electrical pulses to nearby neurons, researchers said. Stimulation can be switched on and off by flipping a switch on an electromagnet, researchers said. The discs successfully stimulated brain regions in mice associated with feelings of reward and…  read on >  read on >

More than 15.5 million U.S. adults have been diagnosed with ADHD, and nearly three-quarters of those taking medication to treat it say drug shortages are hampering their ability to get help, a new report finds. According to the U.S. Centers for Disease Control and Prevention (CDC), a national survey conducted last fall found that 6% of adults have a current diagnosis of attention deficit hyperactivity disorder (ADHD), and just over half (about 56%) received that diagnosis in adulthood. Many aren’t receiving treatment to control the inattention, impulsivity and hyperactivity that characterize the condition.  “Approximately one half of adults (50.4%) with ADHD were prescribed medications to treat their ADHD during the previous 12 months,” noted a team led by Brooke Staley of the CDC’s National Center on Birth Defects and Developmental Disabilities. The vast majority of drug treatments involved stimulant medications such as Ritalin, Vyvanse, Concerta or Adderall. However, recent shortages of these meds are affecting most adult ADHD patients, the study also found. “Among adults who reported taking a stimulant medication, 71.5% reported difficulty getting their ADHD prescription filled during the previous 12 months because their medication was not available,” the CDC team said. That can lead to real problems for patients, because proper medication is tied to “reduced social and emotional impairment, unintentional injuries, substance use disorders, and the risk of death to unnatural…  read on >  read on >

It’s never too late for a person to quit smoking, even if they’re elderly, a new study finds. Dropping the smokes even as late as 75 can meaningfully increase a person’s life expectancy, researchers reported recently in the American Journal of Preventive Medicine. Seniors age 75 will lose on average more than four years of life if they keep smoking, compared to people who never smoked, researchers found. On the other hand, a 75-year-old smoker who quits has a 14% chance of gaining at least one extra year of life, and a 65-year-old smoker a 23% chance. And about 8% of those who quit at age 75 gain at least four years of life compared to those who keep smoking, researchers found. Quitting smoking is the single best thing anyone at any age can do to increase their life expectancy, researchers concluded. “We have seen a remarkable decline in young adult smoking over the past decade. However, rates among older adults who smoke have remained stagnant and, to our knowledge, no research had established the benefits for them of quitting,” lead researcher Thuy Le, an assistant research scientist with the University of Michigan School of Public Health. “We wanted to show that stopping smoking is beneficial at any age and provide an incentive for older people who smoke to quit,” Le added in a university…  read on >  read on >

THURSDAY, Oct.10, 2024Most boys treated with breakthrough gene therapy for a rare but deadly brain illness are faring well six years later, two new reports find. The 77 boys were treated for cerebral adrenoleukodystrophy (CALD), a formerly incurable and progressive genetic brain disease that typically led to a loss of neurological function and early death. However, most patients treated with “eli-cel” gene therapy six years ago are still showing no declines in brain function and remain free of disability, researchers reported Oct. 9 in two studies published in the New England Journal of Medicine. There was a disturbing finding from one of the two studies, however: Six of 35 patients who received one form of the gene therapy have developed blood cancers that seemed tied to the gene therapy. However, the overall news is positive for children who otherwise faced a death sentence, the researchers said. “Cerebral adrenoleukodystrophy is a devastating brain disease that strikes children in the prime of their childhood and development,” explained Dr. Florian Eichler, director of the Leukodystrophy Clinic in the Department of Neurology at Massachusetts General Hospital and lead author of one of the two studies. “When I initially began treating patients with CALD, 80 percent came into our clinic on death’s door, and now the ratio has flipped.” “We cautiously celebrate that we have been able to stabilize this…  read on >  read on >

When it comes to coverage for the pricey GLP-1 weight-loss drugs Wegovy and Zepbound, only a fifth of large U.S. companies cover the medications in their health insurance plans, a new survey shows. In a report published Wednesday in the journal Health Affairs, researchers also found that a third of companies that do cover the medications say coverage has a “significant impact” on their plans’ prescription drug spending. Obesity can fuel poor health and affects a significant chunk of the U.S. population, and these medications can help, the survey authors wrote. However, concerns linger about the drugs’ high costs and the likelihood that they need to be used indefinitely. “Employers are really trying to thread the needle right now,” study author Matthew Rae, associate director for the program on the health care marketplace at KFF, told NBC News. “They’re trying to figure out what is the right balance between the advantages to employees, potential health benefits and the cost of these drugs. And at this point, all of those things aren’t sorted out.” Dr. Susan Spratt, an endocrinologist and senior medical director for the Population Health Management Office at Duke Health in North Carolina, told NBC News the results were “disheartening.” “People who are rich can afford to pay the $1,000 per month for this medication,” she said. “We are just widening health disparities by making…  read on >  read on >

Widely-used acne creams can become contaminated with a known carcinogen even if kept at room temperature, a new study warns. Creams containing benzoyl peroxide (BPO) can wind up containing high levels of benzene while sitting on a store shelf or in a medicine cabinet, researchers found after testing 111 products from major U.S. retailers. Brands tested containing benzoyl peroxide included products from Clearasil, Clean & Clear, Neutrogena, Proactiv, Up & Up and store brand equivalents. Benzoyl peroxide degrades into the carcinogen benzene over time when stored at room temperature, at elevated temperatures and when exposed to the ultraviolet rays of sunlight, researchers reported Oct. 7 in the Journal of Investigative Dermatology. This is the first time that benzoyl peroxide products have been shown to degrade into benzene at normal temperatures, they noted. “Our research demonstrates that BPO products can generate benzene at typical room and store shelf temperatures, while cold storage significantly reduces this formation,” said researcher Dr. Christopher Bunick, an associate professor of dermatology with the Yale University School of Medicine in New Haven, Conn. The Environmental Protection Agency classifies benzene as a known human carcinogen, noting that it specifically increases the risk of leukemia. Benzoyl peroxide acts as an antibacterial agent, and is found in over-the-counter remedies and prescription creams for acne and rosacea. For the new study, researchers bought dozens of acne…  read on >  read on >

The brain has a waste-disposal system that clears away junk proteins that contribute to the development of dementia and Alzheimer’s disease, a new study finds. Advanced imaging scans have revealed a network of fluid-filled structures along arteries and veins within the brain, researchers reported Oct. 7 in the Proceedings of the National Academy of Sciences. These structures allow cerebrospinal fluid to flow through the brain, potentially flushing out waste proteins like amyloid and tau, researchers said. Those toxic proteins build up in the brains of Alzheimer’s patients, creating plaques and tangles that are hallmarks of the disorder. Previous research found these sort of fluid channels in the brains of mice, but this is the first time they’ve been confirmed to exist in humans as well, researchers said. “Nobody has shown it before now,” said senior researcher Dr. Juan Piantino, an associate professor of pediatric neurology in the Oregon Health & Science University (OHSU) School of Medicine. “This shows that cerebrospinal fluid doesn’t just get into the brain randomly, as if you put a sponge in a bucket of water,” Piantino added in a university news release. “It goes through these channels.” For the study, researchers injected five patients undergoing brain surgery at OHSU with a tracer that would be carried with cerebrospinal fluid into the brain. The research team then used MRI scans to track…  read on >  read on >

Damage to the brainstem could be behind the physical and psychological effects of Long COVID, a new study suggests. Brain scans of 30 Long COVID patients found they had damage to the region of the brainstem associated with breathlessness, fatigue and anxiety, researchers reported Oct. 7 in the journal Brain. “The brainstem is the critical junction box between our conscious selves and what is happening in our bodies,” said co-lead researcher James Rowe, a senior research fellow with the University of Cambridge Department of Clinical Neurosciences. “The ability to see and understand how the brainstem changes in response to COVID-19 will help explain and treat the long-term effects more effectively.” Post-mortem studies of people who died of severe COVID-19 early in the pandemic showed changes in their brainstem, researchers said in background notes. “People who were very sick early in the pandemic showed long-lasting brain changes, likely caused by an immune response to the virus. But measuring that immune response is difficult in living people,” Rowe said. “Normal hospital type MRI scanners can’t see inside the brain with the kind of chemical and physical detail we need.” So, the research team turned to more powerful MRI machines called 7-Tesla scanners, which found that COVID infection caused inflammation damage in multiple regions of the brainstem. These abnormalities appeared several weeks after hospital admission, generally in regions…  read on >  read on >
