New research shows that a set of healthy lifestyle habits can help preserve brain function in folks with mild cognitive impairment or early dementia. About 71% of patients who ate healthy, exercised regularly and engaged in stress management had their dementia symptoms either remain stable or improve without the use of any drugs, researchers reported June 7 in the journal Alzheimer’s Research and Therapy. By comparison, about 68% of patients in a control group without these lifestyle changes experienced a worsening of their symptoms, results show. Researchers also found that the more patients changed their lives in healthy ways and stuck to those changes, the greater the benefit for their brain power. This is the first time that lifestyle changes have been shown to have any impact on the progression of dementia and Alzheimer’s, researchers said. “I’m cautiously optimistic and very encouraged by these findings, which may empower many people with new hope and new choices,” said lead researcher Dr. Dean Ornish, founder and president of the nonprofit Preventive Medicine Research Institute. “We do not yet have a cure for Alzheimer’s, but as the scientific community continues to pursue all avenues to identify potential treatments, we are now able to offer an improved quality of life to many people suffering from this terrible disease,” Ornish added in an institute news release. One participant said it…  read on >  read on >

Vigorous exercise more than once a week can lower the risk of dementia for people with high blood pressure, a new clinical trial shows. People who engaged each week in vigorous physical activity had lower rates of mild cognitive impairment and dementia despite their high blood pressure, according to results published June 6 in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, Examples of vigorous activity include hiking uphill, running, fast bicycling, swimming laps, aerobic dancing, jumping rope and heavy yardwork, according to the American Heart Association. “We know that physical exercise offers many benefits, including lowering blood pressure, improving heart health and potentially delaying cognitive decline,” said lead researcher Dr. Richard Kazibwe, an assistant professor of internal medicine at Wake Forest University School of Medicine in Winston-Salem, N.C. This new study offers an idea of how much exercise is needed to reap these benefits, Kazibwe added. The clinical trial involved more than 9,300 participants with high blood pressure aged 50 and older, recruited from about 100 hospitals and clinics throughout the United States. Early results published in 2019 showed that tight control of blood pressure significantly reduced the risk of developing mild cognitive impairment, a precursor of early dementia, researchers said. For this new report, researchers analyzed the effect of exercise on brain health in these folks. Nearly 60% of study participants reported…  read on >  read on >

Drug-resistant fungal infections are appearing in the United States, resulting in highly contagious and tough-to-treat cases of ringworm, also known as jock itch or athlete’s foot, experts warn in a pair of reports. The two fungi reported are among a group that cause skin rashes of the face, limbs, groin and feet, researchers said. Unfortunately, the rashes can look very different from the neat, regular circles seen in most forms of ringworm, researchers said. They might be confused with eczema, and go for months without proper treatment. A man in his 30s developed such a rash on his penis, buttocks and limbs after returning home to New York City from a trip to England, Greece and California, according to a report published June 5 in the journal JAMA Dermatology. Genetic tests revealed the infection was caused by a sexually transmitted form of ringworm called Trichophyton mentagrophytes type VII. The man told doctors he’d had sex with multiple male partners during his travels, none of whom reported similar skin issues. “Healthcare providers should be aware that Trichophyton mentagrophytes type VII is the latest in a group of severe skin infections to have now reached the United States,” said lead author Dr. Avrom Caplan, an assistant professor of dermatology at NYU Grossman School of Medicine in New York City. Infections caused by that fungus are difficult to…  read on >  read on >

While going through menopause, many women who gain weight head to the gym for intense workouts, but new research suggests that too much exercise may help trigger another side effect: hot flashes. In a report published May 29 in the journal Menopause, investigators found that working out too vigorously may raise the risk hot flashes. By how much? Sharp increases in physical activity raised the chances of both objective and subjective hot flashes by 31% and 33%, respectively. “This study shows a link between increases in physical activity and subsequent subjective and objective hot flashes during both waking and sleeping periods,” Dr. Stephanie Faubion, medical director for the Menopause Society, said in a journal news release. “Clinicians may advise patients of this link while acknowledging the multiple well-known benefits of physical activity.” Meanwhile, temperature was only a contributing factor to subjective hot flashes while sleeping, raising the risk of them by 38%. “Because temperature during sleep affected the odds of having a hot flash, modifications such as the use of lighter-weight blankets and sleepwear, as well as keeping the room temperature cooler, may help with nighttime hot flashes,” Faubion added. Hot flashes are one of the most frequently experienced menopause symptoms, with 80% of women experiencing them, researchers said. Previous studies have shown that a drop in estrogen levels triggers changes in the hypothalamus that…  read on >  read on >

A small urban garden can contribute to your health, especially if the garden contains rich soil, a new study shows. A one-month indoor gardening period increased the bacterial diversity of participants’ skin and appeared to improve their response to inflammation, researchers found. Growing, harvesting and consuming food produced in an urban garden every day could help city dwellers fend off disease, researchers suggested. “The findings are significant, as urbanization has led to a considerable increase in immune-mediated diseases, such as allergies, asthma and autoimmune diseases, generating high healthcare costs. We live too ‘cleanly’ in cities,” said lead study author Mika Saarenpaa, a doctoral researcher with the University of Helsinki in Finland. “We know that urbanization leads to reduction of microbial exposure, changes in the human microbiota and an increase in the risk of immune-mediated diseases,” Saarenpaa added in a university news release. “This is the first time we can demonstrate that meaningful and natural human activity can increase the diversity of the microbiota of healthy adults and, at the same time, contribute to the regulation of the immune system.” For this study, participants gardened using regular flower boxes, using plants bought off a store shelf. The crops included peas, beans, mustards and salads. A group of 15 people gardened using naturally derived and microbially rich soil, while another control group of 13 gardened with microbially…  read on >  read on >

For decades, Todd Vogt has been dedicated to the sport of rowing, believing he was in peak physical condition. Then, a series of symptoms began to emerge, turning his life upside down. “My left arm stopped swinging, and I felt incredibly fatigued,” Vogt, 49, recalled. “Eventually, a tremor developed in my hand, and I slowly began to realize something was wrong.” That was in 2018. Since then, he has navigated life with Parkinson’s disease, managing his symptoms and maintaining his rowing career. This summer, he will compete in the Paralympic Games in Paris. But the journey has been anything but easy. Parkinson’s disease affects about 1.5 million people in the United States, with symptoms that include tremor, muscle stiffness, slow movement and problems with coordination and balance. These symptoms typically worsen over time. In Vogt’s case, he faces challenges such as fatigue, weakness and involuntary tremor in his left hand and foot. Despite these obstacles, he believes his rigorous exercise routine has played a crucial role in managing the disease. “I believe all the exercise I’ve been doing has delayed the progression,” he said. Vogt’s introduction to rowing came during his freshman year at the University of Buffalo in 1992. His passion for the sport was immediate, leading him to row competitively throughout college and beyond. After college, he transitioned to coaching, a role that…  read on >  read on >

Some folks like to count their daily steps, while others prefer exercising for a certain amount of time during a day or a week. Luckily, either approach boosts health, a new study finds. Exercise targets based on either step count or minutes are equally associated with lower risks of premature death and heart disease, researchers report in the journal JAMA Internal Medicine. Given this, personal preferences probably are key when setting up an exercise plan, researchers said. “For some, especially for younger individuals, exercise may involve activities like tennis, soccer, walking, or jogging, all of which can be easily tracked with steps,” said lead author Dr. Rikuta Hamaya, a researcher with the Brigham and Women’s Hospital Division of Preventive Medicine in Boston. “However, for others, it may consist of bike rides or swimming, where monitoring the duration of exercise is simpler,” Hamaya added in a hospital news release.  Current U.S. exercise guidelines focus on minutes – at least 150 minutes weekly of moderate to vigorous physical activity, or 75 minutes of vigorous activity. But smartwatches have made it easier than ever to track step counts, raising the question of whether steps would be better suited for setting exercise goals, researchers said. “We recognized that existing physical activity guidelines focus primarily on activity duration and intensity but lack step-based recommendations,” Hamaya said. “With more people using…  read on >  read on >

People who regularly ride bikes throughout their life are less likely to develop knee arthritis, a new study suggests. Bicyclists are 17% less likely to have knee pain and 21% less likely to have symptoms of knee arthritis, compared to people who’ve never biked, researchers discovered. It also appears that people who’ve biked all their lives have a lower risk of knee arthritis than people who’ve only pedaled at one point or another, results show. “Each increase in the number of age periods engaged in bicycling resulted in lower likelihood of reporting knee pain” and knee arthritis detected by both symptoms and X-rays, said lead researcher Dr. Grace Lo, an associate professor of medicine in allergy, immunology and rheumatology at Baylor College of Medicine in Houston. Doctors often encourage regular physical activity to prevent knee arthritis, but some exercises tend to be more effective than others. For this study, researchers analyzed data from more than 2,600 people ages 45 to 79 participating in a study of knee arthritis. About half of the people said they had a consistent history of biking. The participants were asked about their bicycling activities during four age periods of their lives — 12 to 18, 19 to 34, 35 to 49 and 50 or older. These activities could include either outdoor biking or riding an indoor stationary cycle. The new…  read on >  read on >

(HeathDay News) — Following decades of declines, drowning deaths are once again climbing in the United States, new government data shows. More than 4,500 people died from drowning each year in 2020 through 2022, 500 more per year than in 2019, researchers from the U.S. Centers for Disease Control and Prevention found. Increased access to basic swimming lessons and water safety training could save many lives, researchers said. “I’ve seen firsthand the effects of drowning: families forced to say goodbye to their loved ones too soon,” CDC Chief Medical Officer Dr. Debra Houry said in an agency news release. “Understanding the barriers people face to accessing basic swimming and water safety skills training can help us better understand how to address those barriers, decrease drowning rates and save lives,” Houry added. Drowning is the leading cause of death for toddlers ages 1 to 4 in the United States, and the new study found that drowning rates were the highest in this age group. By race and ethnicity, the highest drowning rates were found among Black people  and American Indian/Alaska Native people, researchers found. Nearly 40 million adults (15%) do not know how to swim, and over half (55%) have never taken a swimming lesson, researchers noted. Black people in particular lack swimming skills. More than one in three (37%) Black adults said they don’t know how…  read on >  read on >

Yoga can help improve the long-term health of people with heart failure, a new study has found. “Patients who practiced yoga on top of taking their medications felt better, were able to do more, and had stronger hearts than those who only took drugs for their heart failure,” lead researcher Dr. Ajit Singh of the Indian Council of Medical Research and Manipal Academy of Higher Education in India, said in a news release. Heart failure can have devastating effects on a person’s quality of life, leaving patients tired, breathless and unable to participate in their usual activities, researchers said. The study included 85 patients between 30 and 70 years of age in treatment for heart failure at Kasturba Hospital in Manipal, India. They all had undergone a heart procedure within the past year, and were taking heart medications. Researchers chose 40 people to participate in yoga, and 45 patients to just take their medicine as a control group. Over a week’s time, people in the yoga group were taught a yoga practice that focuses on breathing, meditation and relaxation. They then were advised to continue yoga on their own at home, in 50-minute sessions once a week. Researchers checked the heart structure and function of all participants at the beginning of the trial, six months in and at one year. The team measured the heart’s…  read on >  read on >
