Is male bisexuality real? According to a new review, the answer is a definitive “yes.” “The current study found very strong and consistent evidence that bisexual men do in fact tend to have bisexual arousal patterns,” noted study author J. Michael Bailey. “There is no longer reasonable doubt.” Bailey is a psychology professor at Northwestern University in Evanston, Ill. He and his colleagues came to their conclusion after poring over the findings of eight sexual orientation studies conducted between 2000 and 2019 at four different American, Canadian and British sites. “There has long been a controversy whether men who identify as bisexual are actually bisexual. The bisexual men and many others believe that they are,” Bailey explained. “However, some others — including some scientists and lay persons — have doubted this,” he noted. The reason: a belief that men who claim to be bisexual “are actually either heterosexual or homosexual, and that their claim to be bisexual is based on self-misunderstanding, perhaps due to social pressure not to admit exclusive homosexuality.” Skepticism of female bisexuality — though not the focus of the latest investigation — has largely been more muted, Bailey noted. But Caitlin Ryan, director of the Family Acceptance Project at San Francisco State University, suggests that the controversy surrounding male bisexuality has proved problematic for those who identify as such.

Ten risk factors may affect your risk of developing Alzheimer’s disease, a new Chinese study suggests. Focusing on these factors could help doctors develop guidelines for preventing Alzheimer’s, researchers say. The risk factors include mental activity, obesity in late life, depression, diabetes and high blood pressure. The need is urgent: Alzheimer’s is the most common form of dementia in older people. More than 5 million Americans 65 and older have the disease and the number is expected to nearly triple by 2050, according to the Alzheimer’s Association. For this study, researchers reviewed nearly 400 studies in search of ways to prevent it. Dr. Jin-Tai Yu, professor of neurology at Fudan University in Shanghai, led the search. His team proposed 21 prevention strategies that doctors could use in their practice. Nearly two-thirds of them target risk factors such as high blood pressure and cholesterol and lifestyle. Researchers said 10 suggestions are supported by strong evidence. They include getting as much education as possible in early life; taking part in mentally stimulating activities, such as reading; and avoiding diabetes, stress, depression, head trauma and high blood pressure in midlife. Nine other suggestions had less evidence to support them. They included getting regular exercise and good quality sleep, maintaining a healthy body weight and good heart health in later life, not smoking and getting vitamin C in the… read on >

Even the sickest COVID-19 patients make T-cells to fight the infection, a new study finds. This means that a COVID-19 vaccine will have to cause the body to make T-cells along with antibodies, researchers say. The immune response to the SARS-CoV-2 virus, which causes COVID-19, was the same in American and Dutch patients in the study. “You want vaccine approaches to be grounded in observations from rather diverse settings to ensure that the results are generally applicable,” said study co-leader Alessandro Sette. He’s a professor and member of the La Jolla Institute (LJI) for Immunology’s Infectious Disease and Vaccine Center in La Jolla, Calif. Working with researchers in the Netherlands, his team followed 10 COVID-19 patients who had the most severe disease symptoms. All produced T-cells that worked with antibodies to try to kill the virus and stop the infection. The virus uses spike proteins to enter host cells and many studies are aimed at getting the immune system to recognize and attack this protein, according to an institute news release. Study first author Daniela Weiskopf, a research assistant professor at LJI, said, “This is good news for those making a vaccine using spike, and it also suggests new avenues to potentially increase vaccine potency.” The findings were published June 26 in the journal Science Immunology.

Life in lockdown has led many to overeat and gain weight, a phenomenon referred to as the “COVID-15.” But some small changes can get you back into shape, a weight management specialist suggests. “COVID-19 changed how we eat, what we eat and how we spend our day,” said Dr. Peter Jian, an assistant professor of family and community medicine at the Baylor College of Medicine in Houston. “Unfortunately, for some of us that meant less healthy choices,” Jian added in a Baylor news release. Jian offered these tips for working off the excess pounds and returning to a healthy lifestyle: Learn how to cook. Or start other new hobbies to keep active. “Use this time as an opportunity to focus on the things that we can do in order to improve our health,” Jian said. Stay physically active. If you’re afraid to go to the gym, try biking, hiking and walking outside. You can also join an online fitness program. Eat a healthy diet. Buy nutritious foods with curbside pickup or delivery. If you shop in person, choose foods placed at the front and side aisles, where the fresh and organic produce is available. Avoid prepackaged and processed foods. To lose weight, start small. Gradually introduce new eating and exercise habits. This makes changes easier to adjust to. Stay clear of fad diets. Many of… read on >

Want to make smoking less attractive to young people? Try taking menthol cigarettes off the market, a new analysis suggests. The U.S. Food and Drug Administration banned flavors in cigarettes in 2009 because flavors appeal to youth and young adults, and the agency recently announced that it also intends to ban menthol in cigarettes. To assess what effect a ban on menthol cigarettes would have, Georgetown University researchers reviewed 24 studies on the impacts of restrictions on flavors in cigarettes. Six of the studies examined menthol bans implemented across Canada, 12 assessed the potential effects of hypothetical menthol bans in Canada, the United States and Europe, and six looked at prior bans of non-menthol flavors in cigarettes in Canada and the United States. Based on their review, the researchers concluded that 11%-45% of current U.S. menthol smokers might quit smoking in response to a menthol cigarette ban, while 15%-30% of menthol smokers might switch to e-cigarettes. Menthol smokers quitting or switching to e-cigarettes are more likely to be young adults, and a menthol cigarette ban may reduce the number of youth who start smoking by 6%, according to the researchers. They also found that while overall compliance with the menthol ban in Canada was high, studies into non-menthol flavor bans in the United States found that some retailers continued to sell banned products. The review… read on >

When you’re outside this summer, be sure to protect yourself from the sun, the American Academy of Dermatology (AAD) recommends. Skin cancer is the most common cancer in the United States, and nearly 20 Americans die every day from melanoma, the deadliest form of skin cancer. Along with using sunscreen and seeking shade, wearing protective clothing can reduce your exposure to harmful ultraviolet rays. “The right sun-protective outfit provides long-lasting protection and works great for all skin types and colors,” Chicago dermatologist Dr. Omer Ibrahim said in an AAD news release. “The key is to look for dense fabrics and dark or bright colors and pair those with the appropriate accessories.” Cover as much of your skin as possible when spending time outdoors. Choose lightweight and long-sleeved shirts and pants and avoid fabrics with a loose or open weave such as lace. Keep in mind that dark colors offer more protection than light colors. Sunglasses with UV protection are also important. Lenses that appear dark may not provide that protection, so read the label. Large-framed or wraparound sunglasses protect better than smaller frames, Ibrahim advised. Wear a wide-brimmed hat that protects your face, neck and ears from the sun. Baseball hats or straw hats with holes aren’t as effective. Wear shoes that cover your feet. If you do wear sandals or flip-flops or go barefoot,… read on >

If you plan to celebrate Independence Day, you might want to reconsider setting off fireworks, Prevent Blindness suggests. There are other, safer ways to mark the United States of America’s birthday, according to the nonprofit eye health and safety group. It noted that thousands of Americans are injured by fireworks each year, especially around July 4th. “There are so many ways for families to celebrate Independence Day safely without using fireworks,” said Jeff Todd, president and CEO of Prevent Blindness. “We urge everyone to avoid fireworks and spend the 4th of July with family and friends, instead of in the emergency room,” he added in a news release from the group. Over 19 years, there were more than 34,000 firework-related eye injuries seen in U.S. emergency departments, according to a recent study published in the journal JAMA Ophthalmology. Burns were the most frequent type of eye injury from fireworks. And bottle rockets were a common type of firework that disproportionately caused serious eye injuries. Children aged 10 to 19 had the highest rates of fireworks-related injuries treated at emergency departments, according to the U.S. Consumer Product Safety Commission. Here are some suggestions on safe ways to celebrate the holiday: Decorate 4th of July treats using white frosting, blueberries and raspberries or strawberries. Decorate bicycles, scooters and wagons in red, white and blue and have a… read on >

With communities across the United States canceling Fourth of July celebrations due to the COVID-19 pandemic, backyard fireworks are likely to be more popular than ever. And that has many health experts worried. They fear injuries will soar among amateurs who don’t know how to use fireworks safely. Even before the holiday, explosives are being set off in America’s backyards and on city blocks at unprecedented levels this year. “It’s certainly a risky endeavor to try to use explosives like this without any proper training,” said Maureen Vogel, director of communications at the National Safety Council. But a new nationwide survey suggests that’s a risk many Americans are willing to accept in celebration of the nation’s independence. The online national survey of more than 2,000 adults by Orlando Health in Florida projects that more than two in five Americans will buy fireworks this year and 16% said their purchases were a direct result of COVID-19 cancellations. But despite their ability to dazzle onlookers, fireworks pose significant health risks, doctors warn. “Heading into the holiday weekend every year, I anticipate that we will see some of the injuries that people sustain from fireworks,” said Dr. Eric Adkins, an emergency medicine doctor at The Ohio State University Wexner Medical Center in Columbus. With 80 times as many firework complaints filed in New York City this summer compared… read on >

Despite the existence of conventional medications to manage multiple sclerosis (MS) symptoms, a majority of patients also rely on alternative therapies, including vitamins, exercise and marijuana, a new survey suggests. For the study, researchers at Oregon Health and Science University in Portland asked MS patients if they used “complementary and alternative therapies” — medicines and practices outside of standard medical care. A majority of just over 1,000 respondents said they used some type of alternative therapy, including marijuana, vitamins, herbs and minerals, plus mind-body therapies like exercise, mindfulness, massage and various diets. An earlier survey, conducted in 2001, found some people regularly used these therapies — and many found them helpful — but only 7% were talking to their doctors about them. “It was a little bit of a wake-up call to physicians that they need to be more educated about complementary or alternative therapies, and then consider these therapies as part of the overall treatment plan for their patients,” said lead author Dr. Elizabeth Silbermann, a neurology fellow. MS is a potentially disabling disease that results from the immune system attacking the nervous system and damaging nerves. Symptoms vary, and while some patients eventually lose their ability to walk, others may experience only mild symptoms. MS has no known cure, but treatments can slow the disease’s progression and help patients manage symptoms. “We have… read on >

West Virginia loosened fireworks sales rules in 2016. And since then, the state has seen a 40% boom in fireworks-related injuries, researchers say. The regulation change made it easier for people to buy Class C fireworks such as Roman candles, bottle rockets and fountains. “Since there has been a trend among states to liberalize these laws, I think it is wise for states who may be looking to follow suit to consider the ramifications,” said study leader Toni Marie Rudisill. “If these products are more available, it increases people’s exposure and their likelihood of injuries — not just to children but to adults as well,” said Rudisill, a research assistant professor at West Virginia University School of Public Health. For the study, the researchers analyzed the medical records of patients treated by the WVU Medicine system over two years, including before and after the new law (June 1, 2015 to May 31, 2016 and June 1, 2016 to May 31, 2017). During the study period, 56 people were treated for fireworks-related injuries. Almost two-thirds of patients were older than 25, and 77% were male. The injury rate per 100,000 patients was about 40% higher after it became easier to buy fireworks, according to the study. While fireworks-related injuries increased, there were no changes in injury severity. The most common injuries were burns and cuts, mainly… read on >
