Despite routine use of a childhood vaccine, the United States still sees outbreaks of mumps. Now, a new study reinforces the belief that it’s due to waning immunity post-vaccination. Mumps is a viral infection best known for causing puffy cheeks, a swollen jaw, fever and general misery. While it’s usually relatively mild, mumps occasionally causes serious complications like brain inflammation and hearing loss. Because of that, children in the United States are routinely immunized against mumps, using the measles-mumps-rubella (MMR) vaccine. Yet mumps has seen a resurgence in the past two decades. Since 2006, there has been an uptick in annual cases — often among college-age adults who were vaccinated as children, according to the U.S. Centers for Disease Control and Prevention. Similar patterns have been seen in other countries where vaccination rates are high, leading to two theories on why: waning immunity to mumps in the years after vaccination; or the emergence of new mumps strains that evade the vaccine-induced immune response. The new study — published Jan. 9 in the Proceedings of the National Academy of Sciences — supports the waning-immunity view. Using mathematical modeling, researchers found that waning immunity could largely explain the resurgence of mumps in the United States in recent years. They also estimated that about one-third of vaccinated kids start to lose their mumps immunity by age 18. But… read on > read on >

Anyone who has ever gardened knows what a labor of love it can be as you dig deep in the dirt to plant seeds and then take pride in your first crop, but new research shows it also translates into better health. It turns out that community gardens in urban areas can have folks eating more fresh food and getting exercise, while it can also ease stress and anxiety. “These kind of interventions that have a strong social organization, that have access to nature and contact with nature, where there’s active participation, these are the ingredients that we need to think about to have successful interventions to address a whole variety of health outcomes,” said senior study author Jill Litt. She is a professor in the department of environmental studies at University of Colorado, Boulder, and a senior scientist at the Barcelona Institute for Global Health. For this study, researchers wanted to do a randomized, controlled trial on community gardens, to add to information from previous gardening studies. Litt said she was approached by Denver Urban Gardens to study the benefits when there were only 40 gardens in the city. Now, there are 180. “It hooked me. It was the most fascinating system where we could actually see how behavior change happens,” Litt said. “People were connecting to the landscape. They had social relationships, they… read on > read on >

Gas stoves could face new emissions standards or even be banned because of their link to indoor air pollutants and childhood asthma, according to the U.S. Consumer Product Safety Commission (CPSC). The federal agency will open public comment on gas cooking stoves and their hazards sometime this winter, Bloomberg News reported. “This is a hidden hazard,” agency commissioner Richard Trumka Jr., said in an interview. “Any option is on the table. Products that can’t be made safe can be banned.” About 12% of childhood asthma cases can be linked to gas stove use, according to a recent study in the International Journal of Environmental Research and Public Health. “There is about 50 years of health studies showing that gas stoves are bad for our health, and the strongest evidence is on children and children’s asthma,” said study co-author Brady Seals, a manager in the carbon-free buildings program at RMI, a nonprofit clean energy group. “By having a gas connection, we are polluting the insides of our homes.” About 40% of Americans have natural gas stoves in their homes. The stoves emit nitrogen dioxide, carbon monoxide and fine particulate matter at levels deemed unsafe by the U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO), according to Bloomberg News. In October, Consumer Reports urged readers to buy electric after tests on gas ranges found… read on > read on >

Sperm donation is apparently a grueling and exacting process through which not many men emerge. Fewer than four out of every 100 men who apply to be sperm donors actually wind up providing a sample that’s used in fertility treatment, a new study reports. The rest either give up or wash out, according to findings reported Jan. 9 in the journal Human Reproduction. For the study, researchers tracked the outcomes of more than 11,700 Danish and American men who applied to be donors to Cryos International, one of the world’s largest sperm banks. “The study with Cryos highlights how hard it is to become a sperm donor,” said lead researcher Allan Pacey, head of oncology and metabolism with the University of Sheffield in the UK. “It’s not like blood donation, where once it’s done you can have a cup of tea and go home. Sperm donation is a regular commitment with lots of screening and regular testing as well as lifelong implications for the donor if any children are born from their sample.” Nearly 55% of potential donors were lost during recruitment, researchers found. They either withdrew their application, failed to respond, or stopped showing up to appointments. Nearly a fifth (17%) were rejected on medical grounds. They either had a health issue, carried a genetic disease or had an infectious disease that could not… read on > read on >

TUESDAY, Jan. 10, 2023 (HealthDay News) – Buffalo Bills safety Damar Hamlin is now back in New York. The football player who collapsed on the field after suffering cardiac arrest during a Monday night game in Cincinnati has been released from an Ohio hospital, and will continue his recovery in a Buffalo hospital, the Buffalo Bills football team posted on Twitter. “Mr. Hamlin has been released and returned to Buffalo. I traveled with him to the airport this morning with our UC Health air care and mobile care crew, including teammates who were with us on the field when Mr. Hamlin collapsed,” Dr. William Knight IV, a professor of emergency medicine at the University of Cincinnati College of Medicine and director of the Emergency Medicine MLP Program, told CBS News. Hamlin, 24, collapsed after tackling Bengals receiver Tee Higgins. When Hamlin suddenly collapsed and fell backward, on-field medical staff swiftly gave him CPR before he was taken to Cincinnati Medical Center. The game was postponed and later canceled. The Buffalo Bills played the New England Patriots last Sunday. They finished 13-3, which was a half-game behind Kansas City Chiefs for the AFC’s No. 1 seed, CBS News reported. The Bills would have been No. 1 seed had they won the unfinished game against the Cincinnati Bengals. The Bills will now play a wild-card round against… read on > read on >

The swimmer came to shore struggling to breathe and coughing up blood. A keen competitive long-distance swimmer and triathlete, the woman was fit and healthy when she started a nighttime open water swim event. But a couple weeks earlier, she’d had breathing difficulties during another open water swim that had forced her to abandon the event. She’d felt breathless for days after. The woman, in her 50s, had fallen prey to what’s becoming better known as a hazard associated with open water swimming – fluid on the lungs, or pulmonary edema. Open water swimming has become very popular, but mounting evidence points to a link between the activity and a condition called swimming-induced pulmonary edema (SIPE), according to Dr. James Oldman, lead author of a study published Jan. 9 in BMJ Case Reports. Oldman is a cardiologist with Royal United Hospitals Bath NHS Foundation Trust in the U.K. First reported in 1989, SIPE leaves swimmers struggling to draw breath as fluid collects in the air sacs of the lungs. It affects an estimated 1% to 2% of open water swimmers, but cases are likely to be underreported, Oldman and his colleagues wrote. Older age, long distances, cold water, female gender, high blood pressure and heart disease are among the risk factors for SIPE, the researchers said. However, it often occurs even in those who are… read on > read on >

Children with autism often have difficulty grasping the emotional cues in other people’s voices, and now researchers may have zeroed in on the reason why. In a study of 43 kids with and without autism, researchers were able to trace such difficulties to a particular brain area — one involved in social communication. Experts said the findings suggest that children with autism are processing the sound of vocal emotions without trouble. The stumbling block can arise in interpreting those sounds. Typically, children learn from an early age to link vocal sounds to particular emotions: They know when their parents are happy or sad, even if they do not understand all the words being said. But many children and adults with autism have difficulty “reading” the emotional cues in other people’s voices, which can make communication much trickier. “Having these skills is crucial in navigating our social world,” said Daniel Abrams, one of the lead researchers on the new study. Oftentimes, he noted, people refrain from plainly saying what they’re feeling, and instead signal it in their tone of voice. “The voice can actually tell you more about emotions than a person’s actual words,” said Abrams, a clinical associate professor of psychiatry at Stanford University School of Medicine. It’s well known that autism, a developmental brain disorder, impairs communication and social skills to varying degrees. But… read on > read on >

Older women who don’t stick to a set sleep and wake schedule may be more likely to struggle with feelings of depression and anxiety — even if they get a normal amount of zzzs. What’s more, a postmenopausal woman who goes to bed very early and wakes up very early (an “early bird”) or goes to bed late and wakes up later (a “night owl”) is 70% more likely to experience significant depressive symptoms — even with a normal amount of sleep, a new study suggests. The study wasn’t designed to say whether sleep is the chicken, the egg, or both when it comes to mood. “It could definitely be the case that the women in our study who had depressive symptoms had a different type of sleep schedule because they were depressed, or that their depression was causing them to have more irregular sleep-wake patterns,” said study co-author Leslie Swanson. She is an associate professor of psychiatry at the University of Michigan, in Ann Arbor. More research is needed to tease out the cause and effect between sleep and mood, particularly in postmenopausal women, Swanson said. “Women might be more prone to more irregular sleep patterns as they get older due to factors such as retirement from work or aging of the parts of the brain that control the timing of sleep,” she suggested.… read on > read on >

A leading pediatricians’ group has issued new guidelines on treating obesity in children and teens that, for the first time, call for early, aggressive intervention that can include weight-loss drugs and surgery. “There is no evidence that ‘watchful waiting’ or delayed treatment is appropriate for children with obesity,” Dr. Sandra Hassink, an author of the new American Academy of Pediatrics (AAP) guidelines and vice chair of the Clinical Practice Guideline Subcommittee on Obesity, said in a statement. About 20% of U.S. children now live with obesity, about 15 million children altogether, according to the U.S. Centers for Disease Control and Prevention. The new guidelines recommend against watching and waiting, instead suggesting families of children aged 6 and up should work with their pediatricians on behavior and lifestyle changes. In some cases, families of children aged 2 to 5 should, too, the guidelines recommend. This should include at least 26 hours of counseling over about a year. The new guidelines also suggest that pediatricians should offer obese children aged 12 and up new weight-loss drugs that include Orlistat, Saxenda, Qsymia and Wegovy. Phentermine is approved for kids over 16 years of age, the guidelines said. “The breakthrough that happened in the last few years was people started realizing that there are hormones made in the gut that have multiple roles related to obesity. By targeting these,… read on > read on >

Military service members who conceal their suicidal thoughts are also more likely to store their guns unsafely, a new study reveals. “These findings highlight a real problem with our suicide prevention system,” said Michael Anestis, lead author of the study and executive director of the New Jersey Gun Violence Research Center at Rutgers University in New Jersey. “We know that firearms account for the large majority of suicide deaths within the military and that unsecured firearms at home dramatically increase the risk for suicide,” Anestis said in a Rutgers news release. “Here, we found that suicidal service members less likely to be seen as high risk — those that hide their thoughts from others and avoid behavioral health care — tend to be the service members with the most ready access to their firearms,” he added. For the study, the researchers surveyed more than 700 gun-owning service members. These included active-duty service members throughout all military branches and those in the National Guard and Reserves. The investigators focused on 180 service members who had experienced suicidal thoughts within the past year and another group of 85 service members who had experienced suicidal thoughts in the past month. Surveys asked whether they had ever told anyone about their suicidal thoughts, if they had attended any behavioral health sessions within the past three months and the specific… read on > read on >
