Though coaches and parents are more alert to the need for emergency attention after young athletes suffer a concussion, many may not realize how long symptoms and other effects can linger. A study in JAMA Pediatrics found that 31 percent of concussion victims had persistent symptoms after four weeks, as well as lower quality-of-life scores than kids whose symptoms had resolved. For some, lower quality of life was still an issue at 12 weeks, even after concussion symptoms were gone. And even kids without persistent symptoms had lower quality-of-life scores than typical. It’s important that young athletes don’t return to play too soon. Another JAMA study found that 15 percent return after at least 30 days, but 3 percent did so after fewer than 24 hours, which doesn’t allow time for key return-to-play protocols. Under nationwide guidelines, kids seen in emergency departments must be referred to a health care provider for follow-up care and a plan for a gradual return to school, and to play when fully recovered. They must not return to practice or play the same day or even be told when they could do so by emergency staff. Each child must be evaluated individually. There are five gradual steps for a safe return to play, but they should be started only after a period of physical and mental rest, and after all… 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 >

(HealthDay News) — A good night’s sleep is important for physical and mental health. Long-lasting sleep problems can increase your risk of anxiety or depression, the U.S. National Institutes of Health says. The NIH suggests these ways to manage insomnia: Talk to your doctor. Seek cognitive behavioral therapy or relaxation therapy. Set good bedtime habits. Consider sleep medicine.

You know that too much salt contributes to high blood pressure, but you might not realize how easily eating out could put you and your kids at risk. Many entrees at leading restaurants and fast food places contain almost a full day’s allotment of salt, according to the U.S. Centers for Disease Control and Prevention. Remember, that’s 2,300 milligrams, or about one teaspoon. With many Americans eating out an average of five times a week, all that salt adds up. And the more salt you eat, the greater the odds for high blood pressure (hypertension), a major contributor to heart disease and stroke. By some estimates, the average American takes in 50 percent more salt than the daily limit, and this excess starts in childhood. Kids between 6 and 10 years of age take in 2,900 mg a day, while teens top out at about 3,700 mg. Studies done around the world have looked at salt consumption and high blood pressure. A study of 500 people, aged 18 to 40, found that the more restaurant meals people ate every week, the higher their odds of pre-hypertension. Young people with even a slightly elevated blood pressure level are at very high risk of full-blown hypertension. About 80 percent of the salt consumed has been added by manufacturers of processed foods or at restaurants. While the salt… read on >

Working your triceps might not always be top of mind, but toning the muscles that run along the backs of your upper arms is key to the smooth functioning of your elbows and to also give bare arms a sleeker look. For a study sponsored by the American Council on Exercise (ACE), scientists from the University of Wisconsin, La Crosse, evaluated eight popular triceps strength-training exercises. Tops for Triceps Training Triangle push-ups Triceps kickbacks Overhead triceps extensions Bar push-downs Rope push-downs Closed-grip bench press Lying barbell triceps extensions Dips From this list, triangle push-ups, dips and triceps kickbacks best engaged these muscles. Here’s how to do them. (For each exercise, do 10 to 15 reps for a complete set. Progress from one to three sets as you get stronger.) Triangle push-ups are a variation on the classic push-up. The difference is that the hands are placed next to each other, directly under the upper chest, with thumbs and index fingers making a triangle shape. Flex your feet and contract your core and leg muscles. Keep your head in line with your spine as you slowly lower your body until your chest touches the floor. Focus on moving only your arms. With control, press back up until your arms are fully extended. Repeat. (If this is too hard, you can do the exercise with knees bent… read on >

As American kids pack on the pounds, the number of those with back pain is on the rise. One in three between the ages of 10 and 18 said they had backaches in the past year, according to a survey of about 3,700 youngsters. The incidence rose along with kids’ age and weight and was higher among those who play competitive sports. Though many people probably associate back pain with older people, the orthopedic surgeon who led the study was not surprised by his findings. “We see a lot of kids who have pain from overuse injuries or joint pain from playing sports,” said Dr. Peter Fabricant, who treats pediatric patients at the Hospital for Special Surgery in New York City. “Of these kids who had back pain, very few actually required any sort of medical intervention. Most didn’t need treatment at all.” About 80 percent of adults suffer from lower back pain at some time, according to the U.S. National Institutes of Health. But this is the first time the extent of back pain among children has been estimated on nationwide scale, the authors said. The youngsters surveyed were equally split by age and gender. On average, those who reported back pain weighed more and had higher body mass indexes, or BMIs. (BMI is a measure of body fat based on height and weight.)… read on >

(HealthDay News) — A sprained thumb occurs when ligaments stretch beyond their limits. The most common cause of a sprained thumb is falling onto an outstretched hand, the American Academy of Orthopaedic Surgeons says. Depending on the sprain’s severity, you may have bruising, tenderness and swelling around the base of your thumb. Difficulty grasping things also is common. For mild thumb sprains, the academy recommends the RICE protocol: Rest. Avoid using your hand for 48 hours. Ice. Use cold packs 20 minutes at a time, multiple times per day. Compression. Wear an elastic bandage to reduce swelling. Elevation. Raise your hand higher than your heart as often as possible.

Has your hectic lifestyle turned you into someone who gulps down meals? People who eat quickly tend to eat moreand have a higher body mass index (a measure of body fat based on height and weight) than those who eat slowly. People who eat slowly feel full sooner and eat less in the process. Part of the reason for this is the time it takes for your brain to get key messages from your digestive system. Conventional wisdom says that’s about 20 minutes, and one study found that slowing down to 30 minutes is even more effective. But that means you have to find ways to really stretch out your meals. Tricks like eating with your non-dominant hand can help a lot, but eating fast can be a hard habit to break. One high-tech solution is a commercially available smart fork, a utensil that registers your eating speed and sends a signal, with a vibration and a flash of light, if you eat too quickly. Participants in an experimental study found that it was comfortable to hold and did a good job of making them more aware of their eating speed. But you can also try to slow down on your own with a regular fork: Just put it down and count to 10 between each and every bite. Reinforce the slower eating habit with… read on >

Stretching your leg muscles can improve your flexibility and prevent injury. Here are three stretches that you can do every day and at every age. Start with a calf stretch. Stand at arm’s length from a wall and place your palms flat on the wall at shoulder height for support. Now take one big step backward with one leg. Keep that leg straight as you bend the front knee. Lean forward, but keep your back heel planted firmly on the floor. You should feel the stretch in your lower leg. Hold for 20 to 30 seconds, then switch legs and repeat. Repeat three to five times with each leg. Now move to a hamstring stretch. Lie flat on your back and extend one leg straight up to the ceiling. Loop an exercise band around the ball of that foot and hold the ends of the band firmly around both hands. Now pull on the band to create tension, drawing your foot slightly toward your head. Hold for 20 to 30 seconds, then switch legs and repeat. Repeat three to five times with each leg. Finish with a quad stretch. Stand a few feet in front of a step or low stool. Extend one leg behind you so that you are resting that foot on the step. Bend your front knee slightly without letting it extend… read on >

Kids with poorly controlled asthma struggle in school, especially those who are ethnic minorities, a new study reports. Researchers evaluated asthma and allergy status, lung function and school performance of 216 black, Hispanic (Latino) and white children in a U.S. city. Those with a greater number of daily asthma symptoms had more absences, less school work completed and poorer quality work, according to the study published March 11 in Annals of Allergy, Asthma and Immunology, the journal of the American College of Allergy, Asthma and Immunology (ACAAI). “We found associations between poor asthma status, poorer asthma control, lower lung function, more asthma symptoms and decline in academic performance,” lead author Daphne Koinis-Mitchell said in an ACAAI news release. “These associations were stronger in ethnic minority children, particularly Latino children,” she added. Koinis-Mitchell is a research professor of pediatrics, psychiatry and human behavior at Brown University in Providence, R.I. Poor asthma control could help identify children who might be at risk for problems at school, according to the researchers. The same team previously found that urban Hispanic children with asthma have special sources of stress. “Factors such as higher levels of fear of asthma, language barriers, stress related to fitting in to the culture, poorer symptom perception, greater concerns regarding medications and lower medication adherence may put Latinos at greater risk for poor academic performance,” Koinis-Mitchell… read on >
