More U.S. veterans are at increased risk for heart disease, a looming public health problem, researchers say. They analyzed data from more than 153,000 people who took part in the National Health Interview Survey, conducted by the U.S. Centers for Disease Control and Prevention, in 2012, 2013, 2014 and 2015. Vets between the ages of 35 and 70 reported significantly more heart conditions than non-veterans, the data showed. After age 70, non-veterans reported more, but the study’s author suspects that might be because fewer vets survived into old age due to heart disease. “I think it’s sort of the first indication of a coming public health crisis for veterans,” said study author Ramon Hinojosa, assistant professor of sociology at the University of Central Florida. “Because of the wars in Afghanistan and Iraq, we have a relatively large, new younger generation of veterans who are going to survive for 30 or 40 years after their war experience,” he said in a university news release. The study suggests that what’s known as the “healthy soldier effect” is no longer guaranteed. That’s the tendency for members of the military to be more fit and less overweight than same-age civilians. Hinojosa said the change could be due the nature of modern warfare, changes in diet, leisure and exercise, more obesity among younger vets, and higher rates of drinking, smoking… read on >

Maybe you rush around with work and activities during the day, then settle in for a large, relaxing meal in the evening. But new research says the later in the day you eat, the more weight you’re likely to pack on. That’s the takeaway from a week-long study involving 31 overweight and obese patients, mostly women. “We evaluated meal and sleep timing in patients with overweight/obesity at the beginning of a weight loss trial, before participants started the intervention,” said lead author Dr. Adnin Zaman, an endocrinology fellow at the University of Colorado School of Medicine. Her team found that “eating later into the day was associated with a higher body mass index (BMI) and greater body fat.” BMI is a measure of body fat based on height and weight. For the study, participants were enrolled in a weight-loss trial comparing daily calorie limits to time-restricted feeding. In other words, once the trial launched, they could only eat during certain hours of the day. Ninety percent of the participants were women. Their average age was 36. A week before the study, they were outfitted with electronic devices to monitor their activity and sleep. They also were asked to snap cellphone photos of everything they ate. The photos were time-stamped using an app called MealLogger. Zaman and colleagues did not define which hours would amount to… read on >

Video games provide unlimited entertainment, and interactive ones can even help you burn off calories. But you may not know that playing games — either in person or through shared online networks — can unite family members from many generations in meaningful ways. Researchers at Concordia University in Montreal found that playing social network games, through Facebook for instance, offers family members a fun, common topic of conversation, and creates shared experiences, even though there’s often no direct communication. That’s just one of dozens of studies that have explored the benefits of family gaming. One study done at the University of California, Davis, found that the more often family members play video games together, the greater their feelings of family satisfaction and closeness. What’s more, because those with poor inter-family communication benefited more than those who already had good communication, video gaming can be a bridge to better relationships. Family gaming can easily extend beyond those living in a single household. With more grandparents and other older relatives now using social media to get news about relatives, playing word games and other family-friendly choices can keep the generations better connected because these activities transcend age barriers. Playing can also help connect you to faraway relatives you may not have the chance to get to know in traditional ways. The Concordia researchers also found that people… read on >

Gun-related deaths among school-age children in the United States are increasing at alarming rates, researchers report. In 2017, gun violence claimed more 5- to 18-year-olds than police officers or active-duty members of the U.S. military, according to a chilling new study led by investigators from Florida Atlantic University. “It is sobering that in 2017, there were 144 police officers who died in the line of duty and about 1,000 active duty military throughout the world who died, whereas 2,462 school-age children were killed by firearms,” study senior author Dr. Charles Hennekens said in a FAU news release. He’s a professor of medicine at the university’s Schmidt College of Medicine. The nationwide study found nearly 39,000 gun-related deaths among 5-to-18-year-olds between 1999 and 2017. That included almost 6,500 deaths among kids between 5 and 14 years of age, and more than 32,400 among older teens. Significant increases began in 2009, with a wave of shootings among 5- to 14-year-olds, followed by a similar wave among teens starting in 2014. Both waves — which researchers described as epidemics — continued through 2017, the most recent year for which data are available. Gun-related deaths over the period accounted for 5.6 percent of deaths in the younger group and nearly 20 percent among older kids. Researchers also found statistically significant increases in gun-related deaths among black children aged 5-14,… read on >

Millions of aging Americans worried about heart attacks and strokes have for years popped a low-dose aspirin each day, thinking the blood thinner might lower their risk. But new guidelines issued Sunday by two cardiology groups say that, for most adults, the practice may no longer be warranted. The new heart health guidelines were issued jointly by the American College of Cardiology (ACC) and the American Heart Association (AHA). The two groups agree that for older adults at low risk — no history of heart attack, stroke or cardiac surgeries — the risk of bleeding that comes with daily low-dose aspirin is now thought to outweigh any heart benefit. “Clinicians should be very selective in prescribing aspirin for people without known cardiovascular disease,” Dr. Roger Blumenthal, co-chair of the 2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease, said in a statement. “It’s much more important to optimize lifestyle habits and control blood pressure and cholesterol as opposed to recommending aspirin,” said Blumenthal. He’s a professor of cardiology at Johns Hopkins Medicine in Baltimore. The bottom line, according to Blumenthal: “Aspirin should be limited to people at the highest risk of cardiovascular disease and a very low risk of bleeding.” Why the change? The AHA and ACC say that the most up-to-date research shows that even at a low dose (typically 81 milligrams), the… read on >

No type of bullying is acceptable, but cyberbullying can be harder for parents to spot because it takes place via cellphone, computer or tablet, often through social media. Cyberbullying can be a hateful text message or post of embarrassing pictures, videos and even fake profiles of the victim. Victims are often bullied in person, too, and have a harder time escaping it. But unlike facing a bully at school, cyberbullying can happen 24/7, even when your child is home with you. Messages and images can be posted anonymously and spread in no time. And it can be difficult or even impossible to find the culprit. The consequences of being cyberbullied are far-reaching. Young victims are more likely to use alcohol and drugs, skip school, lose self-esteem and develop health problems. What can parents do? The website Stopbullying.gov recommends being proactive — talk with your kids about cyberbullying, including why they should never bully others, and encourage them to tell you about any incident right away. Friending or following your kids on social media may help you know if they become the victims of unwanted postings. More tips for parents: Teach kids not to share anything that could hurt or embarrass them or others to avoid retaliation. Regularly check your kids’ social network pages to look for signs of bullying behavior, such as mean images of… read on >

The term artificial intelligence (AI) might bring to mind robots or self-driving cars. But one group of researchers is using a type of AI to improve lung cancer screening. Screening is important for early diagnosis and improved survival odds, but the current lung cancer screening method has a 96 percent false positive rate. But in the new study, investigators were able to reduce false findings of lung cancer without missing any actual cases. A low-dose CT scan is the standard diagnostic test for people at high risk of lung cancer. In the United States, about one-quarter of these scans reveal shadows indicating nodules in the lung. Despite that positive result, fewer than 4 percent of those patients actually have cancer. “A positive test creates anxiety, increases health care costs, and the follow-up tests are not risk-free,” said study co-author Panayiotis Benos. He’s vice chairman of computational and systems biology at the University of Pittsburgh. “For the 96 percent of people who have benign nodules, these procedures are unnecessary. So, we try to mine the data to tell which are benign and which are malignant,” Benos explained in a university news release. Benos and his colleagues entered CT scan data from 218 high-risk patients into a machine learning algorithm — a form of artificial intelligence — to create a model that calculates the probability of cancer.… read on >

The switch to Daylight Saving Time can increase the risk of driver fatigue and crashes, but there are a number of ways to reduce the danger, an expert says. “Any time change can exacerbate drowsiness because your internal clock has not adjusted to the time change. This can lead to disruptions in sleep until your body adjusts, which can take a few days to a week,” said Jeff Hickman, a research scientist at the Virginia Tech Transportation Institute in Blacksburg. After clocks spring ahead one hour at 2 a.m. on Sunday, try to avoid driving during rush hours and in early morning, when crash risk increases, he suggested. Driving between 2 a.m. and 4 a.m. is particularly dangerous, because your circadian rhythm is at its lowest during this two-hour period. Drivers should try to sleep at least seven to eight hours, Hickman said. But one night of good rest may not be enough if you have had several sleepless nights. If that’s the case, you’ll need several nights of restful sleep to compensate. Watch for signs of drowsy driving, including slow eyelid closures, yawning, gentle swaying of the head, fidgeting in the seat, trouble staying in your lane, difficulty maintaining speed and slow reactions, Hickman said in a Virginia Tech news release. Be extra careful in situations that increase drowsiness, including driving alone, monotonous road… read on >
