Shingles Won't Raise Risk for Dementia: Study

Shingles Won`t Raise Risk for Dementia: StudyTHURSDAY, June 9, 2022 (HealthDay News) -- If you've survived a painful bout of shingles, at least you won't have to worry that it might raise your future risk of dementia, new research indicates.Shingles, caused by the reactivation of the chickenpox virus, results in a blistering rash from nerve inflammation, and there has been speculation that the inflammation may boost the chances of a dementia diagnosis down the road, so a team of scientists decided to investigate. They analyzed data from more than 247,000 people in Denmark who visited a hospital or were prescribed antiviral medication for shingles over the course of 20 years, and 1.2 million age- and sex-matched people without the illness. The average age of people in the study was 64. Of those who had shingles, 9.7% developed...

No Sign 1 Year of Testosterone Supplements Cause Heart Trouble: StudyTHURSDAY, June 9, 2022 (HealthDay News) -- One year of testosterone therapy for men with low levels of the hormone does not appear to increase their risk for heart problems, British researchers found."We were unable to find evidence ... that testosterone increases risks of mortality or cardiovascular and/or cerebrovascular [heart and/or stroke] events in the short- to medium-term in men with low testosterone," said study leader Dr. Channa Jayasena, head of andrology at Imperial College London.As the researchers explained, testosterone increases hematocrit, which can boost the risk of blood clots (venous thromboembolism) that can travel to the heart or brain.But the potential heart risks of testosterone therapy have been unclear, and previous clinical trials have not provided enough...

Fever, Fatigue: Scientists Pinpoint the Brain`s `Sickness Center` THURSDAY, June 9, 2022 (HealthDay News) -- A small area of your brain triggers the familiar symptoms of fever, chills, fatigue and loss of appetite when you have a viral or bacterial infection, new animal research suggests. The findings could eventually lead to ways to reverse this process when symptoms pose a risk to patients, such as when a fever gets too high or people don't eat or drink enough, according to the Harvard University scientists. It was already known that in response to information from the immune system, the brain causes symptoms of illness when people get sick. But how and where this happens in the brain had remained a mystery.Until now. In the new study with mice, the researchers pinpointed about 1,000 previously unidentified neurons near the base of the brain that...

Isolation May Raise Odds for Dementia, Brain Study Suggests

Isolation May Raise Odds for Dementia, Brain Study Suggests THURSDAY, June 9, 2022 (HealthDay News) -- Staying connected to others may help protect your brain as you age, new research reveals.The study showed that social isolation — but not loneliness — can cause changes to certain brain structures and increase the risk of dementia. The findings suggest that social isolation could be used as predictor of dementia risk, the British researchers added. "There is a difference between social isolation, which is an objective state of low social connections, and loneliness, which is subjectively perceived social isolation," said Edmund Rolls, a neuroscientist in the University of Warwick's department of computer science. "Both have risks to health but ... we have been able to show that it is social isolation, rather than the feeling of...

Weight-Loss Surgery May Greatly Lower Odds for Many CancersWEDNESDAY, June 8, 2022 (HealthDay News) -- Dropping a load of pounds through weight-loss surgery can significantly decrease your risk of developing or dying from cancer, according to three new studies.Obese folks who underwent bariatric surgery were at least two times less likely to develop certain types of cancer and more than three times less likely to die of cancer than heavy people who didn't get the procedure, according to a study presented Tuesday at the American Society for Metabolic and Bariatric Surgery's (ASMBS) annual meeting, in Dallas.Another much larger study by the Cleveland Clinic found similar, if smaller, benefits from weight-loss surgery -- a 32% lower risk of developing cancer and a 48% lower risk of cancer-related death, according to results published June 3 in...

Menthol Cigarettes May Hook Young Smokers Faster: Study

Menthol Cigarettes May Hook Young Smokers Faster: StudyWEDNESDAY, June 8, 2022 (HealthDay News) -- As the U.S. Food and Drug Administration weighs banning the sale of menthol cigarettes, a new study strengthens the tie between mint-flavored tobacco and teen smoking. According to the survey, adolescents who began smoking using menthols tended to smoke an average of nearly three days more during a 30-day period than their peers who took up smoking using regular cigarettes. They also had a 38% higher risk of being a frequent smoker, and an 8% higher risk for nicotine dependency. At the same time, young smokers who switched from menthols to regular cigarettes tended to decrease their tobacco use afterwards. "Menthol cigarettes are a really unique product. They have an almost anesthetic property to them that makes them easier to smoke," noted...

COVID Breakthrough Infections More Likely in People Living With HIV

COVID Breakthrough Infections More Likely in People Living With HIVWEDNESDAY, June 8, 2022 (HealthDay News) -- Even after vaccination, living with HIV ups the odds for COVID infection, new research shows. The study found that vaccinated people living with HIV have a 28% higher risk of developing a "breakthrough" COVID infection compared to those who don't have the AIDS-causing virus.That’s the bad news. But there's good news, too: The overall risk for COVID infection among people vaccinated with at least the two primary doses remains low, regardless of their HIV status.“We thought we might see an increase in the risk of breakthrough in people with HIV because of the impact of HIV on the immune system and the role of the immune system in responding to vaccination and infection from a virus like SARS-Cov-2," reasoned study author Keri Althoff.So,...

Moderna Says Updated Vaccine Tackles OmicronWEDNESDAY, June 8, 2022 (HealthDay News) -- Moderna announced Wednesday that its updated COVID-19 booster shot does a better job at thwarting the Omicron variant than the original version does."We are thrilled to share the preliminary data analysis on mRNA-1273.214, which is the second demonstration of superiority of our bivalent booster platform against variants of concern and represents an innovation in the fight against COVID," Moderna CEO Stéphane Bancel said in a company news release. "Looking at these data alongside the durability we saw with our first bivalent booster candidate, mRNA-1273.211, we anticipate more durable protection against variants of concern with mRNA-1273.214, making it our lead candidate for a Fall 2022 booster. We are submitting our preliminary data and...
