Scientists Get Closer to Understanding 'Hidden' HIV

Scientists Get Closer to Understanding `Hidden` HIVWEDNESDAY, March 29, 2023 (HealthDay News) -- Researchers are closing in on another immune system “hideout” that HIV uses to persist in the human body for years.A subset of white blood cells called myeloid cells can harbor HIV in people who’ve been virally suppressed for years, according to a new small-scale study funded by the U.S. National Institutes of Health (NIH).The researchers showed that HIV in specific myeloid cells can be reactivated, with the virus going on to infect new cells. These specific cells include short-lived monocytes and longer-lived monocyte-derived macrophages.The results suggest that myeloid cells contribute to a long-lived reservoir of HIV in those infected, researchers said.In that case, the white blood cells would be an important but overlooked target...

Blind People Are Better at Sensing Their HeartbeatsWEDNESDAY, March 29, 2023 (HealthDay News) -- People who are blind are better at sensing their own heartbeats, according to a new study that found blindness appears to heighten one's ability to feel signals from the inner body.Researchers from Sweden and Poland tested this in a study of 36 blind individuals and the same number of sighted people.Each was asked to count their heartbeats without checking their pulse or touching their body.Using a pulse oximeter, the researchers simultaneously recorded participants' actual heartbeats. Then, they compared the reported numbers with those actually recorded.Among participants who were blind, average accuracy was 0.78, while the sighted group averaged 0.63 on a scale where 1.0 represented a perfect score.“The blind participants were much...

Having Asthma, Eczema Might Raise Arthritis Risk

Having Asthma, Eczema Might Raise Arthritis RiskTUESDAY, March 28, 2023 (HealthDay News) -- If you’re one of the millions of people with allergic asthma or eczema, you may be more likely to develop the wear-and-tear form of arthritis as you age.This is the main finding from a new study that examined the risk of developing osteoarthritis among people with the two allergic conditions.The study wasn’t designed to say how, or even if, these allergic diseases increase osteoarthritis risk, but the researchers do have a theory. “Our group has done work showing that mast cells [a type of allergic cell] are increased in numbers in the joints of people with osteoarthritis, and their activity contributes to the development of osteoarthritis,” said study author Dr. Matthew Baker, clinical chief in the division of immunology and...

Rate of Kids Hospitalized in Mental Health Crisis Keeps RisingTUESDAY, March 28, 2023 (HealthDay News) -- Children with mental health problems are flooding America's hospitals.A new study of 4.8 million pediatric hospitalizations between 2009 and 2019 found that the number of acute care hospitalizations for kids with mental health problems increased significantly. In 2019, most were due to attempted suicides, suicidal thoughts or self-injury, researchers said."What we’re seeing are more and more hospital stays by children and adolescents due to mental health concerns in terms of absolute numbers, and a substantially larger fraction of these stays are related to suicide or self-injury," said study leader Mary Arakelyan, research project manager at Dartmouth-Hitchcock Medical Center in Lebanon, N.H."With hospitalizations for mental health...

Weight Loss Helps Your Heart Even If Some Weight Comes BackTUESDAY, March 28, 2023 (HealthDay News) -- It can be downright discouraging to work hard to lose 10 pounds, only to regain a few later.But don’t be downhearted -- a new evidence review says the important heart health benefits of weight loss are sustained even if some of the weight comes back.People who drop some pounds still have lower blood pressure and better cholesterol and blood sugar numbers even if they regain a little, British researchers reported March 28 in the journal Circulation: Cardiovascular Quality and Outcomes.“It should serve as encouragement for people to try to lose weight, and do so in the most effective way by joining a behavioral weight loss program,” said senior researcher Paul Aveyard, a professor of behavioral medicine at the University of Oxford....

Hidden Heart Disease Can Raise Your Odds for Heart Attack 8-Fold

Hidden Heart Disease Can Raise Your Odds for Heart Attack 8-FoldTUESDAY, March 28, 2023 (HealthDay News) – Millions of middle-aged folks may be walking around with no symptoms of heart disease, and yet they still face a higher risk for a heart attack, new research shows.What gives? Subclinical or silent heart disease may be responsible. This is the early thickening or hardening of the heart arteries that can worsen over time and cause crushing chest pain, known as angina, or even a heart attack. Middle-aged folks with such subclinical heart disease face a much higher risk of a surprise heart attack, researchers discovered.But they were quick to caution that the absolute risk of having a heart attack without any signs or symptoms remains low.“Subclinical heart disease refers to changes of the circulatory system that are mainly seen with advanced...

Do Sweat It: Could 'Body Odor Therapy' Ease Anxiety?

Do Sweat It: Could `Body Odor Therapy` Ease Anxiety?TUESDAY, March 28, 2023 (HealthDay News) -- Could inhaling a deep whiff of another person’s sweat help ease crippling social anxiety? Quite possibly, new Swedish research suggests.The notion stems from a trial that involved just 48 women. All struggled with what’s known as social anxiety disorder — an often intense and relentless fear of being watched or judged by others when participating in common social situations.The standard course of treatment centers on talk therapy involving meditation practices that are designed to ease some of the anxiety that arises.But Swedish researchers discovered that when such “mindfulness therapy” is combined with the inhaling of sweat of others, the result appears to be a far steeper drop in anxiety levels.“Social anxiety is a common...

Child`s Hospital Stay Can Cost Plenty, Even With InsuranceTUESDAY, March 28, 2023 (HealthDay News) -- When a child is hospitalized, cost may not be the greatest worry but the out-of-pocket expense can be substantial in the United States, even for those with insurance.A Michigan Medicine study found that U.S. families covered by private insurance spend an average of $1,300 out of pocket for a child’s hospital stay.And about 1 in 7 of those families pays more than $3,000.“Bills for a child’s hospitalization can be astonishingly high for some families depending on how their insurance plan is structured,” said lead author Dr. Erin Carlton. She is a pediatric intensivist at University of Michigan Health C.S. Mott Children's Hospital, in Ann Arbor.“For families without savings, these bills could have negative impacts on their family’s...
