Narcissists may seem self-assured, but new research shows they often feel excluded — and their behavior may be making things worse. Hallmarks of narcissm include an inflated sense of one’s importance, a hunger for admiration and negative response to criticism. The new research — published Feb. 20 in the Journal of Personality and Social Psychology — found that folks with those personality traits are more likely to be left out socially than their peers. And this rejection only reinforces their narcisstic behaviors, creating what the authors described as a self-perpetuating cycle. “Ostracism — being excluded and ignored — has severe, negative consequences,” they wrote. “Many people think of narcissism in terms of entitlement and arrogance, but our research highlights that narcissists also frequently experience social pain,” lead researcher Christiane Büttner of the University of Basel in Switzerland told The Washington Post. To explore the link between narcissism and exclusion, researchers analyzed data from multiple surveys and experiments conducted in Germany, the U.S., Britain, Switzerland and New Zealand. The study focused on “grandiose narcissists.” These are folks who display dominance, rivalry and are extra sensitive to social cues. This form of narcissism differs from “vulnerable narcissism,” which is more closely linked to insecurity, researchers noted. “One of the biggest questions going into this research was whether narcissists might actually report less ostracism because their grandiose self-image…  read on >  read on >

Frequent exercise can help colon cancer survivors live longer, perhaps even outlasting average folks, a new study suggests. Colon cancer patients who were very physically active had three-year survival rates that were slightly higher than the general population, researchers report in the journal Cancer. “This new information can help patients with colon cancer understand how factors that they can control — their physical activity levels — can have a meaningful impact on their long-term prognosis,” lead researcher Justin Brown, director of the Cancer Metabolism Program with the Pennington Biomedical Research Center at Louisiana State University, said in a news release. For the study, his team pooled results from two National Cancer Institute-sponsored trials studying people treated for stage 3 colon cancer. In the trials, nearly 2,900 participants reported their levels of physical activity, which researchers translated into metabolic equivalents, or MET-hours per week.  Results showed that participants who got 18 or more MET-hours of exercise per week had an overall three-year survival rate 3% higher than the general population. To put that in perspective, health guidelines recommend 150 minutes of moderate-intensity exercise each week, which is equal to about 8 MET-hours per week. “Cancer survivors who were tumor-free by year three and regularly exercised achieved even better subsequent survival rates than those seen in the matched general population,” researchers noted in a news release.

MONDAY, Feb. 24, 2025 (HealthDay news) — Even slight weight loss spurred on by cutting-edge GLP-1 drugs can help prevent replacement knees and hips from wearing out, a new study suggests. People with new knees and hips are significantly less likely to need follow-up surgery to fix wear and tear on their artificial joint if they lose weight using Wegovy, Zepbound or other GLP-1 drugs, researchers reported in a new study published Feb. 21 in JAMA Network Open. Patients who lost 2% to 10% of their initial weight had an overall 25% lower risk of follow-up surgery, and those who lost 10% or more had a 43% lower risk. “A higher proportion of weight loss after initiating antiobesity medications within 1 year was associated with a lower risk of 5-year and 10-year revision among patients with obesity undergoing joint replacement,” concluded the research team led by Dr. Chao Zeng, an orthopedics specialist with Ziangya Hospital at Central South University in Changsha, China. “These results suggest that antiobesity medication use, with relatively safe and sustainable weight loss, may be an effective strategy for improving implant survivorship of hip and knee replacement in the obese population,” researchers added. In the U.S., about 900,000 knee replacement surgeries and 400,000 hip replacements occur each year, researchers said in background notes. Knee replacements can be expected to function well for…  read on >  read on >

A parent’s mental health appears to influence their kids’ chances of developing anxiety, ADHD and other behavioral disorders, a new study says. Children were more than four times as likely to develop severe ADHD (attention-deficit/hyperactivity disorder) if their caregiver had poor or fair mental health, compared to kids of caregivers in excellent mental health, researchers found. Likewise, kids’ chances of severe anxiety were nearly six times higher if their caregiver reported poor mental health, according to results published late last year in the journal Pediatric Reports. “Our study highlights the lasting impact of caregiver mental health on childhood disorders,” particularly anxiety, behavioral problems and ADHD, senior researcher Lea Sacca, an assistant professor of population health and social medicine at Florida Atlantic University, said in a news release. “The COVID-19 pandemic, which increased the time children spent with caregivers, revealed a strong connection between severe childhood anxiety and lower caregiver mental health, suggesting that these effects may be long-term rather than temporary,” she added. The new study aimed to track behavioral, mental and developmental problems among 6- to 11-year-olds between 2019 and 2022, using annual federal survey data on child health. Overall, the survey gathered data on nearly 52,000 children. It found significant associations between caregivers’ mental health and children’s risk of mental or behavioral disorders. For example, 2020 survey data showed that caregivers with poor…  read on >  read on >

People taking the weight-loss drug semaglutide could be at a slightly increased risk for a potentially blinding eye condition that affects the optic nerve, a new study says. Patients on semaglutide (Ozempic, Wegovy) had a 32% increased relative risk of developing nonarteritic anterior ischemic optic neuropathy (NAION) compared to people not taking the drug, researchers reported Feb. 20 in JAMA Ophthalmology. NAION typically causes sudden vision loss in one eye, according to Brigham and Women’s Hospital.  It’s thought to occur due to a loss of blood flow to the optic nerve, damaging the neurons that transmit images to the brain. Previous studies also have detected this risk. A 2024 study based at Mass Eye and Ear in Boston reported a more than fourfold increased risk of NAION with semaglutide, researchers said in background notes. That study also appeared in JAMA Ophthalmology. The new study provides “further evidence of an association between semaglutide and NAION but show a smaller risk than that previously reported,” concluded the research team led by Dr. Cindy Cai, an assistant professor of ophthalmology at Wilmer Eye Institute at Johns Hopkins. However, the new study also found that patients prescribed semaglutide did not have a significantly increased risk for NAION compared with other GLP-1 diabetes medications. More research is needed to confirm this link and to identify why semaglutide might have this…  read on >  read on >

Fainting can be scary, but it’s often harmless. Known medically as syncope, fainting happens when there’s not enough blood flow to the brain, causing a brief loss of consciousness. But how do you know if it’s just a simple faint or something more serious? Dr. Elijah Behr, a cardiologist at Mayo Clinic Healthcare in London, shares five key facts about fainting: what causes it, how to prevent it and when to see a doctor. Most fainting is harmless, but not always The most common type of fainting is vasovagal syncope, often triggered by emotional stress, pain, illness or dehydration. “In some people, if they have a drop in blood pressure from emotional distress, pain, illness or dehydration, for example, or just generally have a low blood pressure, any provocation causes a reflex in the heart,” Dr. Behr explained in a news release. “Rather than the heart speeding up and pumping more forcefully to maintain the blood pressure, it starts to slow down. The blood pressure drops, the heart rate slows further, and the heart can pause for many seconds; sometimes close to a minute for some people who have more severe fainting episodes.” While simple fainting usually resolves quickly, cardiac syncope — caused by an underlying heart problem — can be more serious. “This is usually a more abrupt loss and return of consciousness than…  read on >  read on >

Turns out, Americans may be drinking less coffee, soda and tea, but they’re getting more caffeine than ever. A new study of more than 49,000 U.S. adults found that while fewer are sipping caffeinated drinks, those who do are choosing much stronger doses, with coffee taking the lead. The result? Caffeine intake is rising, even though the average consumption is still below 400 milligrams of caffeine per day. That’s the amount health experts consider safe. “We are all aware that the caffeinated beverage market has changed dramatically over the past 10 years, yet no comparable, comprehensive caffeine intake data have been published in recent years,” study author Diane Mitchell of the Institute for Advancing Health through Agriculture, Texas A&M AgriLife, said in a news release. Coffee now accounts for 70% of total caffeine consumption, up 15% from the previous 2010-2011 survey, Mitchell’s team reported. What’s more, carbonated soft drinks now contribute only 15% of caffeine intake, a 27% decrease from a decade ago. Tea consumption has also dropped significantly, with 50% fewer tea drinkers overall. However, the remaining tea drinkers nearly doubled their caffeine intake from tea, suggesting those who stuck with the beverage are, in fact, drinking more. Energy drinks, which were less common a decade ago, now account for 6% of total caffeine intake, as the number of available brands has jumped from…  read on >  read on >

Got milk? It turns out, plain cow’s milk, water and a bit of veggie juice are still the best drink choices for kids and teens. That’s the consensus of experts who recently issued healthy beverage recommendations for kids and teens aged 5 to 18. The expert panel — convened by Healthy Eating Research, a national program of the Robert Wood Johnson Foundation — included members from  the Academy of Nutrition and Dietetics, the American Academy of Pediatric Dentistry, the American Academy of Pediatrics and the American Heart Association. Its recommendations follow a five-month review of scientific literature, according to The Washington Post. Unsurprisingly, the panel said water should be “primary beverage for meeting hydration needs,” with the recommended daily intake ranging from 16 to 88 ounces, depending on a child’s age and sex.  Tap water, the panel wrote, is preferred because it’s affordable, eco-friendly and often has fluoride added to prevent tooth decay. Plain pasteurized milk — preferably low-fat or fat-free — was also recommended for its essential nutrients. The panel said 100% fruit or vegetable juice is acceptable but should be limited due to its high calorie content. The panel also said plant-based milks, like almond or oat, lack key nutrients and should only replace dairy if medically necessary. It said flavored and sweetened milk should be avoided or limited. Sugar-sweetened beverages, like sodas…  read on >  read on >

One of the NBA’s most exciting rising stars will spend the rest of the 2024-2025 season on the bench. Victor Wembanyama, the San Antonio Spurs’ 7-foot 3-inch phenom, was sidelined after doctors discovered a dangerous blood clot in his right shoulder, the league announced Thursday. The 21-year-old French standout, who earned Rookie of the Year honors last season, was diagnosed after his return from Sunday’s 2025 All-Star Game with deep vein thrombosis (DVT).  DVT is a dangerous condition in which a blood clot forms in a vein deep inside the body, usually in the legs but sometimes in arms or shoulders, as in Wembanyama’s case.  “The medical experts and the people that are smarter than everybody in the room … confirm that he’ll be done this year, and that there is no concern for Victor’s long-term health personally, or anything related to his basketball activities,” acting Spurs coach Mitch Johnson said, according to the Associated Press. DVT can develop after after injuries, surgery or long periods of inactivity such as a long car or plane trip, according to the U.S. Centers for Disease Control and Prevention (CDC). If left untreated, the clot can break loose and travel to the lungs, causing a life-threatening pulmonary embolism. Clots can also block blood flow to the brain or heart, increasing the risk of stroke or heart attack, experts…  read on >  read on >

The health benefits of aggressive blood pressure control outweigh the potential risks for seniors, according to the latest results from a major clinical trial. About 85% of seniors treated to a target blood pressure of 120 systolic (the top number in a blood pressure reading) had a positive net benefit from such tight control, researchers reported. The reduced risk of heart disease and early death outweighed the negatives that can accompany such aggressive treatment, which include potential kidney damage or dangerously low blood pressure, results show. “Almost all … participants aged 65 years or greater had a predicted net benefit that favored an systolic blood pressure target of less than 120 mm Hg over a systolic blood pressure target of less than 140 mm Hg,” concluded the research team led by senior investigator Dr. Simon Ascher, an assistant clinical professor with the University of California-Davis. Systolic blood pressure refers to pressure within blood vessels during a heartbeat. Elderly patients, frail seniors and those taking many different medications derived “greater absolute harms from intensive blood pressure lowering,” along with greater heart disease, cognitive and death rate benefits, the study found.  These results come from the Systolic Blood Pressure Intervention Trial (SPRINT), which in 2017 led major U.S. cardiology groups to revise their definition of high blood pressure. As a result, blood pressure of 130 systolic has…  read on >  read on >
