Regular exercise has a long list of health benefits, and a new study suggests another one could be added: a lower risk of Parkinson’s disease. The study, of nearly 99,000 French women, found that those who were most physically active day to day were 25% less likely to develop Parkinson’s over three decades, versus women who were more sedentary. That does not prove that exercise, per se, is responsible, the researchers said. At the same time, they say it’s unlikely that the link reflects “reverse-causation” — women in the earliest stages of Parkinson’s being less likely to exercise. That’s because the study assessed the women’s exercise habits for up to 20 years before their Parkinson’s diagnosis. And since regular exercise clearly has benefits anyway, the findings could be seen as another motivator to get moving, said senior researcher Dr. Alexis Elbaz. “Physical activity has beneficial effects on many body systems, including the bones, heart and lungs,” said Elbaz, a research professor at the French national research institute INSERM in Paris. “And our findings show that physical activity might also contribute to preventing or delaying Parkinson’s disease.” Parkinson’s disease affects nearly 1 million people in the United States, according to the Parkinson’s Foundation. It is a brain disease that gradually destroys or disables cells that produce dopamine, a chemical that helps regulate movement and emotional responses.…  read on >  read on >

Pregnancy is a difficult and potentially dangerous time in a woman’s life, and U.S. women say they aren’t getting the support they need while they’re expecting, a new HealthDay/Harris Poll has found. Nearly 2 in 5 women who are pregnant or have ever been pregnant (37%) say they have experienced barriers to getting needed care. Worse, women in their prime childbearing years (18 to 34) are more than twice as likely as those who are 35 and older to say they encountered barriers to needed health care during pregnancy and birth — 74% versus 28%. The most common barrier they cite is an inability to make doctor’s appointments because of they are unable to take time off work or find child care. One in 5 women overall (19%) — and 2 in 5 between 18 and 34 (39%) — cite that as a reason they didn’t get the care they needed, poll results showed. As a result, women are nearly unanimous in their support for paid maternity leave and better health care in pregnancy: Nine in 10 women (92%) think maternity leave is crucial for improving mothers’ health outcomes, including 64% who strongly agree. Nine in 10 women (91%) also think maternity leave is key to improving babies’ health outcomes, including 61% who strongly agree. More than 4 in 5 women (86%) say more must…  read on >  read on >

The first RSV vaccine designed to protect infants is under consideration by a panel of advisers to the U.S. Food and Drug Administration. An independent committee of experts will vote Thursday on whether to recommend the shot for pregnant mothers at 24 to 36 weeks gestation. “Before the pandemic, RSV was the No. 1 cause of infant hospitalization in the United States, so this is a big deal,” Dr. Ofer Levy, director of the precision vaccines program at Boston Children’s Hospital, told NBC News. Levy is a temporary voting member of the panel, but not one who will vote on this vaccine. If the panel recommends the vaccine, the FDA would still need to approve it, a process that could take months. The agency is not obligated to follow its advisers’ recommendations, but it usually does. The Pfizer-made vaccine would only be the second one ever approved in the United States for RSV (respiratory syncytial virus). A vaccine made by pharmaceutical company GSK was approved for adults ages 60 and up earlier this month. However, 11 RSV vaccines for various age groups are being tested in ongoing clinical trials. When a mother-to-be receives the vaccine, protective antibodies transfer to infants through the placenta. Safety data for the infant vaccine is “generally favorable,” according to the FDA. Trial participants had a slightly elevated rate of preterm…  read on >  read on >

It’s a wonderful thing to try to save stray animals, but for some people it can turn into a form of hoarding thats dangerous for pets and humans alike. People who “hoard” animals may feel like they’re saving them, but caring for many pets may take a toll on their well-being and that of the animals they take in, according to a new study. “Although most folks with hoarding disorder collect objects, for some folks their main struggle is having more animals than they can care for,” said lead author Mary Dozier, an assistant professor of psychology at Mississippi State University. “Most research on animal hoarding has focused on extreme cases,” she said in a university news release. “We wanted to look at what normative patterns of animal ownership look like, particularly in a rural setting, and if there were any trends we could discover related to animal health.” To do that, Dozier and her colleague Ben Porter examined a decade’s worth of records from MSU’s College of Veterinary Medicine. The study looked for the number of cats and dogs per household and indicators of animal health. This included positive indicators, such as dental visits, and negative ones, such as hydration problems. Dozier said people who have animal hoarding disorder may not recognize that these tendencies are impacting the health of their pets. The researchers…  read on >  read on >

Men, want to burn fat? Chill out. New research shows that exposure to cold in the morning may help you burn more fat than at other times of day. Exposure to cold activates brown fat, producing heat to help the body maintain its temperature and burn calories, especially those from fat. That makes it an ideal way for guys to improve cardiometabolic health — preventable conditions like heart attack, diabetes and liver disease, for instance. Sorry, ladies. The same may not be true for you. “Our study indicates that the optimum time to undergo cold exposure is at a specific point in the body’s 24-hour cycle,” said study co-author Mariëtte Boon, of Leiden University Medical Center in the Netherlands. “It may also be that there is a sex difference in how the body responds to cold exposure with respect to boosting metabolism at a certain time point, and it appears that delivering cold exposure therapies in the morning may be more beneficial than the evening for men.” The investigators set out to determine whether there was a circadian (time-influenced) rhythm in humans’ brown fat activity, and if there were any differences between men and women. In rodents, brown fat metabolic activity fluctuates throughout the day, peaking just before waking up, the study authors noted. Heat production from food digestion and activity declines at night. Waking…  read on >  read on >

When young men pack on excess weight during their teens and 20s, they may inadvertently drive up their risk for prostate cancer later on. The concern stems from new research that examined several decades’ worth of weight fluctuations and prostate cancer rates among nearly 260,000 men in Sweden. The men ranged in age from 17 to 60. Researchers initially observed that overall, participants who put on roughly 1 pound or more per year across their life span had a 10% higher risk for developing aggressive prostate cancer as older adults. A similar weight pattern was linked to a 29% greater risk of fatal prostate cancer. But digging deeper, researchers found that most of the men grew heavier between the ages of 17 and 29. And ultimately most of the weight-associated increase in cancer risk was pegged to weight gains in that age bracket. “We were surprised [by] the rapid weight gain in young adulthood, and that the risk of prostate cancer later in life was strongly associated with this rapid weight gain,” said lead author Marisa da Silva, a postdoctoral fellow at the Lund University Cancer Center in Sweden. She stressed that the findings are not definitive proof that youthful weight gains caused prostate cancer risk to rise, only that the two are linked. Even the possibility of a weight-driven risk factor is important, da…  read on >  read on >

Combining a swallowable gastric balloon with a weight loss drug may be a way to lose significant body weight, a new study suggests. In about eight months of combination treatment, participants lost an average of 19% of their body weight, and significantly reduced their body mass index (BMI), researchers report. “Combination therapy gives providers much flexibility and further options in managing obesity in patients who need additional weight loss or increased durability,” said lead researcher Dr. Roberta Ienca, from the Nuova Villa Claudia Clinic in Rome, Italy. “The ease of use and low rate of adverse events make it an ideal primary weight loss therapy that can be complemented by medications or other treatments,” she added. Gastric balloons for weight loss are not new, but they haven’t been popular because they require an endoscopy for placement, the study authors said. This new swallowable balloon from Allurion Technologies eliminates the need for a medical procedure. (Ienca and her two co-authors are advisors for Allurion.) In the noninvasive procedure, the balloon is swallowed as a capsule and is filled with liquid after it reaches the stomach. The outpatient procedure takes about 20 minutes. After about 16 weeks, the balloon is excreted naturally. The balloon reduces the amount of food that can be ingested, which leads to weight loss. Taking the diabetes drug liraglutide (Saxenda) enhances feelings of…  read on >  read on >

Skip artificial sweeteners if you’re trying to lose weight, warns the World Health Organization (WHO), noting the sugar substitutes aren’t effective for shedding pounds and may also cause harm. Long-term use of sugar substitutes may cause “potential undesirable effects,” according to new WHO guidance. This can include an “increased risk of type 2 diabetes, cardiovascular diseases, and mortality in adults,” CBS News reported. Consuming foods and beverages with ingredients like saccharin or sucralose or adding them to foods “does not confer any long-term benefit in reducing body fat in adults or children,” the WHO said after completing a systematic review. Among the artificial sweeteners WHO officials considered were acesulfame K, aspartame, advantame, cyclamates, neotame, saccharin, sucralose, stevia and stevia derivatives, according to the news report. “People need to consider other ways to reduce free sugars intake, such as consuming food with naturally occurring sugars, like fruit, or unsweetened food and beverages,” said Francesco Branca, WHO director for nutrition and food safety. Artificial sweeteners “are not essential dietary factors and have no nutritional value. People should reduce the sweetness of the diet altogether, starting early in life, to improve their health,” Branca added. These recommendations do not apply to people who already have diabetes, according to the review. That group was not included in the review. This isn’t the only time these artificial sweeteners have raised…  read on >  read on >

Kids whose families left distressed neighborhoods had significantly fewer severe asthma attacks, with improvements greater even than those seen with medication. New research found that children whose families participated in a program that enabled them to move to areas with less poverty, and better schools and parks had about 50% fewer severe attacks. After moving, there were about 40 severe asthma attacks per year for every 100 children, compared to 88 before the move. “That degree of improvement is larger than the effect we see with asthma medications,” said senior study author Dr. Elizabeth Matsui, a professor of population health and pediatrics at Dell Medical School of the University of Texas at Austin. “We were also surprised to find that improvements in neighborhood stressors, including feeling safer in their new community and experiencing better social cohesion with neighbors, seemed to be major factors in the improvements in asthma,” Matsui added in a university news release. The study attributed between 20% and 35% of improvement in asthma symptoms to a reduction in neighborhood-related stress. The study included 123 children, aged 5 to 17, whose families enrolled in a six-year housing mobility program in Baltimore. After moving, children had asthma symptoms just three days over two weeks, compared to five days before. “These findings confirm what we’ve long suspected: A big part of the asthma burden is…  read on >  read on >

Many American women fear childbirth, and the COVID-19 pandemic did not calm those feelings, new research shows. “Our results showed really high rates of childbirth fear in our sample,” said Zaneta Thayer, co-author of a new study and an associate professor of anthropology at Dartmouth College in Hanover, N.H. Moreover, childbirth fear was linked to higher odds for preterm birth, the researchers found. “Since there’s no pre-pandemic U.S. data, we cannot compare our data to that context but we know that the rates are very high compared to other international studies on the subject that have been published pre-pandemic,” Thayer said in a college news release. About 62% of study participants had clinically high levels of childbirth fear, also known as “tokophobia,” the researchers found. The figure among Black mothers was much higher. They had a 90% higher chance of having childbirth fear than white mothers, which may reflect experiences with racism during their obstetric care, the study authors said. The researchers also found that people in the lowest household income category, $50,000 or less per year, and those with no college degree had high levels of childbirth fear. High-risk pregnancy, prenatal depression and a pre-existing health condition were also associated with childbirth fear. For the study, the researchers used data from an online survey conducted from April 2020 to February 2021. It included prenatal…  read on >  read on >
