Less than half of patients with a sports-related mild traumatic brain injury (mTBI) recover within two weeks, new research shows. “This study challenges current perceptions that most people with a sports-related mTBI recover within 10 to 14 days,” said lead author Dr. Stephen Kara, from Axis Sports Medicine in Auckland, New Zealand. He and his colleagues analyzed recovery time in nearly 600 patients in New Zealand treated during a two-year period for sports-related mTBI. More than 3 out of 4 were male, and their average age was 20. About 7.5% were under age 12. All patients followed a standard protocol. It included 48 hours of “relative rest,” meaning they avoided mental and physical tasks that could aggravate their head injury. They then gradually increased such tasks. After 14 days, 45% of patients had recovered, the study found. Recovery rose to 77% after four weeks and to 96% eight weeks after injury. Recovery time was similar across all age groups. However, current guidelines from the global Concussion in Sports Group (CISG) say that nearly all sports-related concussions resolve within 10 days. U.S. guidelines for youth concussions call for follow-up care from a health care provider after the emergency room visit, then a plan for gradual return to school and play when fully recovered. Each person should be evaluated individually. The study findings appear in the March…  read on >

The coronavirus crisis has millions of Americans questioning whether it’s wise, or even safe, to travel this spring. Now, an infectious disease expert has created a checklist to help you decide whether to go ahead with your trip or cancel it. COVID-19 is an illness caused by a new coronavirus. For most people with healthy immune systems, infection appears to result in mild symptoms — similar to a cold or flu. However, infection appears to be most severe, and occasionally fatal, for the frail elderly or those with chronic health issues or compromised immune systems. Dr. Susan Wootton, an infectious disease pediatrician at the University of Texas Health Science Center in Houston, has developed this nine-point checklist to help you decide whether your trip is a go or a no. If your answer matches the response in parentheses to each question, move on to the next question. If not, you may need to rethink your travel plans. Are the travelers healthy? (Yes.) Have the travelers received flu shots? (Yes.) Do any of the travelers or anyone the travelers have had contact with have any underlying high-risk conditions for the virus, such as chronic obstructive pulmonary disease? (No.) Are any travel restrictions for your destination listed on the U.S. Centers for Disease Control and Prevention or U.S. Department of State websites? (No.) Is the trip a…  read on >

If you are feeling the aches and pains of what you think is the flu, a trendy diet may be the culprit instead, a new study confirms. Researchers took a dive into what’s become known as “keto flu” — the fatigue, headache, nausea and mental fog that some people develop soon after starting a ketogenic diet. The keto diet, which is loaded with fat and skimpy on carbs, has become a popular way to lose weight. By depriving the body of carbs — its main source of fuel — the diet pushes it to burn fat instead. The tactic “undeniably works” in spurring quick weight loss, said Ginger Hultin, a Seattle-based registered dietitian and spokesperson for the Academy of Nutrition and Dietetics. At the same time, though, it can leave people feeling miserable, at least in the first few weeks. That so-called keto flu has been recognized for some time, and it’s thought to be the result of the radical dietary change. Keto plans typically recommend getting 70% to 80% of calories from fat, 10% to 20% from protein, and a mere 5% to 10% from carbs. “You’re asking your body to shift into a completely different metabolic state,” Hultin explained. For the new study, researchers looked to online forums to see what keto dieters had to say about their short-term side effects. First, they…  read on >

Coronavirus is officially a pandemic, and Americans are adopting “social distancing” to prevent a surge in potential illnesses and death. So, what if you run a fever or experience shortness of breath? Should that send you running to an emergency room? Not necessarily, since most coronavirus cases are mild and there’s no need to panic, experts note. The first thing to do is match your symptoms to those experienced by COVID-19 patients, said Dr. William Jaquis, president of the American College of Emergency Physicians (ACEP). Fever, a dry cough and shortness of breath are the three most common symptoms, Jaquis said. Headaches, body aches, sore throat and fatigue sometimes occur but are more often associated with the flu, medical experts say. A runny nose rarely occurs with COVID-19, and sneezing is not a symptom of the virus. Next, assess the severity of your symptoms. Don’t just rush to the hospital. If you can still breathe reasonably well or your fever responds to over-the-counter remedies like acetaminophen (Tylenol), you should call your family doctor to discuss your best options for care, experts say. According to Dr. Aimee Moulin, an emergency medicine physician with the University of California, Davis, “If your symptoms are mild, you can reach out to your primary care physician, and if you feel like you can manage at home, folks are advised to…  read on >

Brain inflammation may be more of a factor in dementia than previously believed, a new British study suggests. “We predicted the link between inflammation in the brain and the buildup of damaging proteins, but even we were surprised by how tightly these two problems mapped on to each other,” said co-author Thomas Cope of the Department of Clinical Neurosciences at the University of Cambridge. The findings could lead to new treatments for several types of dementia, his team said. Brain inflammation has been linked to depression, psychosis, multiple sclerosis and Alzheimer’s disease. In this study, the researchers investigated whether brain inflammation is also associated with other types of dementia. They used brain scans to assess 31 patients with three types of frontotemporal dementia (FTD). FTD is a family of conditions caused by the buildup of abnormal “junk” proteins in the brain. In all three types of FTD, the more inflammation there was in each part of the brain, the greater the buildup of harmful junk proteins, the study found. To confirm that link, researchers analyzed 12 brains donated after death. “There may be a vicious circle where cell damage triggers inflammation, which in turn leads to further cell damage,” study co-author Richard Bevan Jones said in a university news release. James Rowe, a professor of neurosciences at the Cambridge Center for Frontotemporal Dementia who was…  read on >

Vaccines protect you and your family against a number of diseases, so it’s crucial to keep them updated, health experts say. “It’s important to review your vaccination records with your health care provider,” said Libby Richards, associate professor of nursing at Purdue University in West Lafayette, Ind. “Vaccinations aren’t just for kids. Adults need them, too.” Which shots adults need depends on age and health history. Vaccines help the immune system fight infections faster and more effectively. Common vaccinations include shingles, pneumonia, Tdap (tetanus, diphtheria and pertussis), influenza, MMR (measles, mumps, rubella), hepatitis A and B and human papillomavirus (HPV), along with others. Flu vaccination is particularly important, especially in severe flu seasons, according to the U.S. Centers for Disease Control and Prevention. You need a flu shot every year, Richards noted. Since October, at least 26 million Americans have had the flu, resulting in the deaths of at least 14,000 adults and 92 children. In its latest update on Feb. 14, the CDC said flu activity remains high in the United States. Even if you had other vaccines in childhood, their effectiveness can weaken over time, so you may no longer be protected, Richards said. “Pertussis — whooping cough — and tetanus vaccines are perfect examples of vaccines that require booster shots throughout one’s life,” she said in a university news release. Shingles vaccines…  read on >

More than 200,000 people in the United States have pulmonary fibrosis, but more than eight in 10 Americans don’t know the symptoms of the lung disease, a new survey finds. Pulmonary fibrosis is a progressive disease that causes scarring of the lungs. Symptoms include persistent, dry cough, shortness of breath and fatigue. There is no known cure. An online survey of more than 2,000 U.S. adults was conducted by the Pulmonary Fibrosis Foundation, and found that 86% did not know the symptoms of pulmonary fibrosis. The most common form of pulmonary fibrosis is idiopathic pulmonary fibrosis, which has no known cause. Certain people are at increased risk for idiopathic pulmonary fibrosis, including those older than 60 and those with a history of smoking. But the survey found that among respondents aged 60 and older, 91% didn’t know the symptoms of pulmonary fibrosis and 96% had never talked to their doctor about the disease. The rates among current or former smokers were more than 80% and 91%, respectively. People with a history of smoking were three times more likely to have pulmonary fibrosis or know someone affected by the disease, the findings showed. “Awareness of pulmonary fibrosis and its symptoms remains very low, and for many, the first time they hear of it is when they are diagnosed,” said William Schmidt, president and CEO of the…  read on >

Few heartbreaks are as devastating as when a beloved family dog falls ill with cancer. But a new research paper could spur development of more and better treatments for a canine companion who has a brain tumor — because it’s possible that those same therapies will help human kids, too. Dogs’ brain cancers are genetically akin to those found in children, a new study in the journal Cancer Cell reports. “These dog tumors were much more similar to the tumors we find in kids than the tumors we find in adults,” said senior researcher Roel Verhaak, associate director of computational biology at The Jackson Laboratory in Farmington, Conn. “This is important because it means whatever results we find in preclinical experimental therapy studies involving canines is going to be most applicable — and maybe even only applicable — to children’s brain tumors,” he added. Striving to cure pet dogs with brain tumors and learning which therapies work best — and why — could inform cancer treatments for children with these tumors, the researchers concluded. It’s been thought for some time that family dogs might be better for testing experimental cancer drugs than lab animals like mice or monkeys, said Dr. Len Lichtenfeld, deputy chief medical officer for the American Cancer Society. That’s because dogs live tightly alongside humans, sharing the same exposures from home and…  read on >

Your morning cup of coffee may help your focus and problem-solving skills, but it won’t kick-start your creativity, a new study says. “In Western cultures, caffeine is stereotypically associated with creative occupations and lifestyles, from writers and their coffee to programmers and their energy drinks, and there’s more than a kernel of truth to these stereotypes,” said study first author Darya Zabelina, an assistant professor of psychology at the University of Arkansas. Increased alertness, heightened vigilance, greater focus and improved motor performance are known to be associated with caffeine, but its impact on creativity is less known, Zabelina noted. She and her colleagues assessed the effects of caffeine on 80 volunteers’ convergent and divergent thinking, working memory and mood. Convergent thinking is used in problem-solving while divergent thinking is used in creativity. Volunteers were given either a 200 milligram (mg) caffeine pill — equivalent to one cup of strong coffee — or a placebo. Caffeine improved convergent thinking but had no real impact on divergent thinking. Researchers also found that caffeine didn’t significantly affect working memory, but it appeared to affect mood — those who took it reported feeling less sad, according to the study in the March issue of the journal Consciousness and Cognition. “The 200 mg [of caffeine] enhanced problem-solving significantly, but had no effect on creative thinking,” Zabelina said in a university…  read on >

Hitting the slopes or the skating rink as the winter of 2020 winds down? Don’t let an accident or injury spoil your fun. “Winter sports and recreational activities have great health and cardiovascular benefits,” said Dr. Joseph Bosco, vice president of the American Academy of Orthopaedic Surgeons (AAOS). “However, it’s important not to underestimate the risks that cold weather can bring.” He noted that hospitals and health care clinics see a surge of bone and joint injuries during the winter months and many could be prevented with the right preparation. Sprains, strains, dislocations, fractures and more traumatic injuries can happen to anyone. Here, Bosco and the AAOS offer suggestions on how to protect yourself: Be prepared: Before you tackle a winter sport, make sure your muscles are warmed up and in good condition. Cold muscles, tendons and ligaments are more prone to injury. Make sure to have water and other supplies on standby. Wear appropriate gear: Well-fitting protective equipment like goggles, helmets, gloves and padding is crucial. Your clothes should be layered, light, loose and wind-resistant. Footwear should be warm, provide ankle support and keep your feet dry. Follow the rules: If you’re unsure of the rules of your sport, it’s time to take a lesson with a qualified instructor, especially with sports like skiing and snowboarding. Knowing how to fall correctly and safely can…  read on >
