Love to cuddle up? It might bring a ‘mind meld,’ too, new research shows. People in close physical contact appear to have synchronized brain patterns, a revolutionary new MRI technique has revealed. A functional MRI scan of two people cuddling under a blanket showed that their brains appeared to be falling into similar patterns of action and response, as they took turns gently tapping the other’s lips, a Finnish research team reports. “In general terms, it shows how the brains of two individuals become ‘tuned in’ together during this kind of elementary human interaction,” said senior researcher Lauri Nummenmaa, head of the Human Emotion Systems laboratory at the University of Turku in Finland. Research of this sort could be valuable in dealing with conditions where people have trouble with social interactions, he said. “Such processes are disrupted in numerous conditions, such as autism spectrum disorder, and understanding the elementary mechanisms of sociability will help us in understanding these conditions better,” Nummenmaa said. Here’s how participants were positioned in the scanner: It’s not surprising that the 10 couples in the study — either friends or romantic partners — appeared to have had synchronized brain responses, said Tiffany Field, director of the Touch Research Institute at the University of Miami. “There’s this intimacy that generates similar patterns of physiological and biochemical responses, and this is a good… read on >

You can’t hug or shake hands these days without risking coronavirus infection, but new research finds that sexual intercourse might be safe. Researchers analyzed semen samples from 34 men in China an average of one month after they were diagnosed with mild to moderate cases of COVID-19, the illness caused by the coronavirus. Laboratory tests did not detect the coronavirus in any of the semen samples, and there was no evidence of the virus in the men’s testes, according to the study published online recently in the journal Fertility and Sterility. While this small study suggests that the chances of sexual transmission of the coronavirus are remote, it wasn’t comprehensive enough to fully rule out the possibility, the researchers noted. “The fact that in this small, preliminary study that it appears the virus that causes COVID-19 doesn’t show up in the testes or semen could be an important finding,” said study co-author Dr. James Hotaling, an associate professor of urology specializing in male fertility at University of Utah Health. “If a disease like COVID-19 were sexually transmittable, that would have major implications for disease prevention and could have serious consequences for a man’s long-term reproductive health,” he said in a university news release. Along with the small number of patients, another limitation of the study was that none of them were severely ill with COVID-19,… read on >

Contact lens users may be at increased risk for coronavirus infection, so they need to be extra careful, an eye expert says. “There are no confirmed cases of COVID-19 transmission by handling of contact lenses,” said David Chu, assistant professor of ophthalmology at Rutgers New Jersey Medical School, in Newark. “However, since contact lenses can cause eye irritation, wearers tend to touch their face or to rub their eyes more often, which puts them at a higher risk for acquiring infection.” Strict hygiene is essential when wearers handle their contacts. “They must wash their hands for a minimum of 20 seconds with soap and water, and dry their hands completely before handling contact lenses,” Chu said in a Rutgers news release. Standard contact lens care techniques should be adequate during the coronavirus pandemic. But people who are more vulnerable to COVID-19 or who live with someone diagnosed with the virus should consider switching to glasses, Chu suggested. Even though SARS-CoV-2, the virus that causes COVID-19, has been found in human tears, it seems to be uncommon, Chu said. In case studies, patients who tested positive for the virus in their nose and throat did not have detectable levels in their tears. It’s not clear whether tears can transmit COVID-19, but it appears unlikely, according to Chu. Conjunctivitis (“pink eye”) is a symptom of COVID-19, but… read on >

Beware of your fridge, pantry and couch during the coronavirus pandemic. Being cooped up at home with easy access to food can lead to overeating. Couple that with routine housekeeping, working from home, homeschooling your kids and tending to loved ones, and it’s a sure-fire recipe for weight gain, experts at the University of Georgia in Athens warn. “These tasks have been added to our many other responsibilities,” said Emma Laing, director of dietetics in the College of Family and Consumer Sciences. “So if something has to give as we strive to find our new normal, routines surrounding eating and physical activity might go out the window.” To stay on track, get up off the couch. Try to set times during the day for physical activity you enjoy, and to eat regular meals and snacks that provide adequate energy and hydration. “In creating this schedule, do so while maintaining flexibility,” Laing said. “It’s important to trust our bodies’ cues for hunger, so listen to those first.” Try to avoid mindless snacking. Social distancing during the coronavirus pandemic doesn’t mean you have to stop exercising. In fact, physical activity is a crucial stress management strategy. Ali Berg, a Cooperative Extension nutrition and health specialist, pointed out that “physical activity is good for maintaining immunity, in addition to adequate nutrition. Being active is also good for mental… read on >

Children of parents with mental illness are at increased risk for injuries, researchers report. Risk is highest before 1 year of age, but remains elevated to age 17, according to the new study. “Our results show there is a need for increased support to parents with mental illness, especially during the first year of life,” said Alicia Nevriana. She is one of the study authors and a Ph.D. student in the global public health department at the Karolinska Institute in Sweden. “There are already recommendations for new parents to ensure their children’s safety, but we think there is a need to update these recommendations also by taking into account parents’ mental health,” Nevriana said in an institute news release. For the study, the researchers analyzed data from 1.5 million children in Sweden born between 1996 and 2011. More than 330,000 had at least one parent diagnosed with a mental illness during that period or five years earlier. Those up to age 1 year had a 30% higher risk of injuries if they had a parent with a mental illness when compared with other kids. The risk declined as children got older, but was still 6% higher among those aged 13 to 17, the findings showed. The risk of injuries was slightly higher if parents had common mental disorders, such as depression, anxiety or stress-related illnesses,… read on >

As you shelter at home during the coronavirus pandemic, eliminate hazards inside that could lead to falls, the American Academy of Orthopaedic Surgeons (AAOS) suggests. Preventing injuries will help avoid putting added strain on a health care system struggling to treat COVID-19 patients, academy spokesman Dr. Todd Swenning said. One out of five falls causes a serious injury, such as a broken bone or even head trauma, he added. “While common perception is that falls only happen to older populations, the truth is that anyone is susceptible, especially with increased family members in the home or changes to your daily routine,” Swenning said in an academy news release. “The good news is that most falls can be prevented with a few simple precautions.” Start with your footwear. Wear sturdy and proper footwear, make sure your shoes are properly tied, don’t wear socks without grips, and replace stretched out or loose slippers, Swenning advised. In the bedroom: Place a lamp, telephone or flashlight near your bed; have a bed that’s easy to get into and out of; put a nightlight between your bedroom and the bathroom; and arrange clothes in your closet so that they’re easy to reach. In other areas of your home: Arrange furniture so there are clear paths between rooms; install easy-access light switches at room entrances so you don’t have to walk… read on >

Can zinc help shorten a COVID-19 infection? Will vitamin C or other supplements prevent it? These claims and plenty more can be found on social media and internet sites, but be advised: There is no pill or treatment that can prevent or cure COVID right now. “We want to think that there is a quick way to get rid of this. But there is not a product out there that will keep you from getting the coronavirus,” said Rebecca Dutch, a virologist with the University of Kentucky in Lexington. The pandemic has spawned a wave of products claiming to protect you by boosting your immune system — a simple claim people think they understand, said retired psychiatrist Dr. Stephen Barrett, who runs Quackwatch, a website that debunks pseudoscientific claims. “They think, ‘If I can boost my immune system, I’ll be more resistant to the virus,’” but it’s just not that simple, he said. “The immune system is quite complex,” Barrett explained. “There’s not even a scientific process called strengthening or boosting the immune system.” He agreed with Dutch: “There is no product you can take that will prevent or cure COVID,” he said. Even a group representing supplement makers agreed. Two major industry groups –the Council for Responsible Nutrition and the American Herbal Products Association — recently asked stores selling dietary supplements to refuse to… read on >

Once you’ve had COVID-19 and recovered, are you now immune from the virus? That’s the critical question that will help shape how the United States re-opens for business in the coming months. Unfortunately, there’s still no clear answer. It’s still too soon to tell if the first wave of COVID-19 survivors will remain immune to the virus for any appreciable length of time. But the nation’s top infectious disease expert, Dr. Anthony Fauci, thinks there’s a good chance that people might gain lasting immunity following COVID-19 infection. “We’re making an assumption, which I think is a reasonable assumption, that this virus is not changing very much,” said Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases. “If we get infected in February and March, and recover, next September or October the person who was infected I believe is going to be protected. We don’t know 100% for sure, but I think that is a reasonable assumption.” But there’s also reason to question the potential for lasting immunity against COVID-19, said Dr. Greg Poland, director of the Vaccine Research Group at the Mayo Clinic, in Rochester, Minn. Immunity may vary The novel coronavirus behind COVID-19 belongs to a family of viruses that has a very uneven track record with the human immune system, Poland noted. “With the four seasonal beta coronaviruses that circulate… read on >

It’s clear that age and chronic disease make bouts of the pandemic coronavirus more severe — and even deadly — but obesity might also put even younger people at higher risk, a pair of new studies suggest. The researchers suspect that inflammation throughout the body linked to obesity could be a powerful factor in the severity of COVID-19, the disease caused by the coronavirus. And, they added, it could even be more significant than heart or lung disease. “This has relevance in the U.S., where 40% of Americans are obese, and will no doubt contribute to increased morbidity and likely mortality, compared to other countries,” said Dr. Jennifer Lighter, co-author of one of the studies. Lighter is an assistant professor of pediatric infectious diseases at NYU School of Medicine in New York City. Though people under age 60 are generally considered at low risk for COVID-19, her team found that those who are obese are twice as likely to be hospitalized for the disease. And, compared to patients whose weight is normal, those who are morbidly obese are twice as likely to need acute care and three times more likely to be confined to the intensive care unit, the study found. Though patients studied were obese, none had diabetes or heart disease, Lighter said, but they might be on the verge of them. “They have… read on >

New research suggests that having an underlying health condition might be one of the most significant risk factors for developing a severe case of COVID-19. Scientists at the U.S. Centers for Disease Control and Prevention took a look at a group of U.S. adult COVID-19 patients and found roughly three-quarters of those who wound up in the hospital had at least one underlying health issue. For 457 patients who were admitted to intensive care, 78% had other health conditions, while 71% of 732 patients admitted to the hospital, but not intensive care, had at least one other health issue. The mortality data showed an even stronger correlation: Among all hospitalized COVID-19 adult patients with complete information on underlying conditions or risk factors, 184 deaths occurred. Of those, 173 (94%) involved patients with at least one underlying condition, according to the CDC’s COVID-19 Response Team, led by researcher Nancy Chow. Those conditions include diseases that strike people of all ages, including asthma and diabetes, along with heart disease and lung disease. Unfortunately, those very conditions are quite common among Americans, the researchers noted: In 2018, the prevalence of diagnosed diabetes among U.S. adults was just over 10%, while the prevalence of heart disease was 10.6% in 2017. Meanwhile, the prevalence of COPD (chronic obstructive pulmonary disease) among U.S. adults was almost 6% and the prevalence of… read on >
