Should Fluffy and Fido go vegan? A new study says yes — for the environment. The United Nations Food and Agriculture Organization estimates that livestock are responsible for 14.5% of the greenhouse gas emissions. In response, some experts say eating vegan — meaning a nutritionally sound diet without animal proteins or products — for two-thirds of meals could slash food-related emissions by 60%. “Vegan pet food is clearly associated with very large savings in greenhouse gas emissions, land and water use, and a range of other environmental parameters,” said Dr. Andrew Knight, a professor of philosophy at Griffith University in Australia, who led the new study. “If implemented globally, such diets would also save the lives of billions of ‘food’ animals annually, and enable the feeding of billions of additional people (and dogs and cats), with the food energy saved.” The new study said American dogs and cats consume about one-fifth as much meat as their human counterparts and about one-tenth of that worldwide. Recent research suggests that nutritionally sound vegan diets — lacking meat, eggs and dairy — are safe for pets and may have comparable health benefits, the study noted. If all U.S.-based dogs and cats went vegan, researchers estimated that the lives of 2 billion livestock animals a year could be saved, along with billions of aquatic animals.

A nasal spray containing a ketamine derivative appears to beat one of the standard drugs used for people with difficult-to-treat depression, a new clinical trial has found. The trial, of nearly 700 people with treatment-resistant depression, found that esketamine nasal spray was more effective at sending patients into remission than a standard oral drug called quetiapine (Seroquel). After eight weeks, 27% of esketamine patients were in remission, versus 18% of those given quetiapine. By week 32, half of esketamine patients were faring that well, compared with one-third of those on quetiapine. Experts said the findings, published in the Oct. 5 issue of the New England Journal of Medicine, strengthen the case that esketamine is a good option for people with treatment-resistant depression. The condition, which plagues up to 30% of people with depression, is generally diagnosed when a person’s symptoms have failed to yield to at least two standard antidepressants. It’s a situation that places people at increased risk of hospitalization and suicide. There are a few medications approved in the United States as an “augmentation” therapy for treatment-resistant depression — meaning they are used along with a standard antidepressant. Quetiapine is one of them, and so is esketamine nasal spray, which has been available since 2019 under the brand-name Spravato. That approval was based on research testing esketamine against a placebo nasal spray. The… read on > read on >

In the United States, “conversion therapy” for LGBTQ people has been widely condemned by major medical associations. Not only that, nearly half of the country has now banned the practice for minors. But a new review of 16 investigations across six nations suggests conversion therapy is hardly a thing of the past. On average, nearly one of every 10 LGBTQ individuals around the world say they have been exposed to the highly problematic practice at some point in their lives, researchers found. Such practices “include organized attempts to deter someone from adopting or expressing an LGBTQ identity or a gender identity that differs from [their] sex assigned at birth,” explained study lead author Travis Salway. He is an assistant professor with the Simon Fraser University Centre for Gender and Sexual Health Equity, in Canada. But “the vast majority of research on conversion practices to date demonstrates limited to no effectiveness, and substantial risk of harm, including depression, anxiety and, in some cases, suicide,” Salway added. Nevertheless, after reviewing studies conducted in the United States, the United Kingdom, Australia, Canada, Colombia and South Korea, Salway’s team found “conversion practices remain prevalent, with approximately 8% of LGBTQ people having been exposed in their lifetime.” That figure did vary considerably from country to country, rising to 13% in the United States, while falling to 7% across Canada.

More than 80% of eligible Americans did not get a COVID-19 booster shot last fall. Now, a new study reveals the reasons for the hesitation. Nearly 40% of survey participants said a prior COVID-19 infection factored into their decision to not get the booster. Another 31.5% were worried about side effects. And an additional 28% didn’t think a booster would provide extra protection, while 23% said it wouldn’t protect from the new coronavirus. “Our results indicate that we have a lot more work to do in terms of educating the public and health care providers about the importance of staying up to date on COVID-19 boosters,” said first study author Elizabeth Jacobs. She is a professor of epidemiology at the Zuckerman College of Public Health at the University of Arizona Health Sciences, in Tucson. This research was done through Arizona CoVHORT, which began in May 2020 to track the effect of COVID infection on Arizonans. Researchers hope the results, published in the Oct. 6 issue of the journal Vaccine, will help encourage interventions to get more people vaccinated. A variety of strategies may be needed to improve vaccination rates, as age, ethnicity and education affected reasons for hesitation, according to the study. “Our results indicate that many people don’t know that a booster provides additional protection even if they have already been infected or that… read on > read on >

Going vegetarian is trendy and popular, along with being a healthy choice, but a large portion of those who say they want to stick with a plant-based diet don’t. It might come down to your DNA, suggests new research that has uncovered three genes that seem to be strongly linked to vegetarianism. “It seems there are more people who would like to be vegetarian than actually are, and we think it’s because there is something hard-wired here that people may be missing,” said corresponding study author Dr. Nabeel Yaseen, a professor emeritus of pathology at Northwestern University Feinberg School of Medicine in Chicago. As many as 48% to 64% of people who identify as vegetarian still report eating fish, poultry and/or red meat, the study authors pointed out in a university news release. To study the impact of genes on eating behavior, the scientists compared UK Biobank genetic data from more than 5,300 strict vegetarians — those who ate no fish, poultry or red meat — to more than 329,000 non-vegetarians (the “control” group). The investigators found 31 genes that are potentially associated. Several of these genes, including two of those most closely associated, are involved in metabolizing fat and/or brain function. “One area in which plant products differ from meat is complex lipids,” Yaseen said. “My speculation is there may be lipid component(s) present… read on > read on >

While studies of ADHD and driving usually target teens, a new one focused on seniors found they have a significantly higher risk of car crashes. Older adults with attention-deficit/hyperactivity disorder (ADHD) were also more likely to slam on the brakes and get traffic tickets, the study found. “Little is known about ADHD in seniors,” said senior author Dr. Guohua Li, an epidemiology professor at Columbia University Mailman School of Public Health in New York City, explaining the motivations for studying this issue. “Secondly, the population has been aging and continues to grow older, and there are more and more older adult drivers on the road.” The United States has about 48 million older drivers, a number that could reach 63 million within seven years, he noted. This study included more than 2,800 drivers between 65 and 79 years of age. About 2.6% had ADHD. The researchers linked ADHD to a 74% increased risk of crashes, a 102% increased risk in self-reported traffic tickets and a 7% increased risk of hard braking events. ADHD is a neurodevelopmental condition that is often diagnosed during childhood and can persist throughout life. About 8% of adults aged 18 to 44 are known to have ADHD, the researchers said in background notes, as are 9% to 13% of children under 18. ADHD symptoms that might contribute to driving challenges include… read on > read on >

New research has discovered 12 gene variants that may be tied to an increased risk of attempting suicide. These genes also may have links with physical and mental health woes, including chronic pain, attention-deficit/hyperactivity disorder (ADHD), lung conditions and heart disease. The researchers hope this finding, published online Oct. 1 in the American Journal of Psychiatry, will lead to better understanding of the biological causes of suicide. “Many people who die from suicide have significant health conditions associated with that risk,” said study corresponding author Anna Docherty, an associate professor of psychiatry at the Huntsman Mental Health Institute (HMHI) at the University of Utah. “If we can use genetic information to characterize the health risks of those who attempt suicide, we can better identify those patients who need contact with the mental health care system.” For the study, the investigators analyzed data from 22 different populations, including people of diverse ethnic backgrounds. What they found wasn’t one single gene influencing risk, but the cumulative effect of different genes. “In psychiatry, we have many tiny genetic effects, but when we account for all of them together, we start to see a real genetic risk signal,” Docherty explained in a university news release. To assess that risk, the team broke down data from the Million Veteran Program and the International Suicide Genetics Consortium. That data included nearly… read on > read on >

In yet another reminder of the psychic toll the pandemic has taken on young people, new research shows spending on mental health services for U.S. children and adolescents has risen sharply since 2020. It climbed 26% for youths aged 19 and younger between March 2020 and August 2022, the RAND Corp. study found. Among a large group whose families had employer-provided insurance, use of mental health services increased by 22%. Use of telehealth for young patients skyrocketed more than 30-fold in the early days of the pandemic and remained 23 times higher than normal by August 2022. In-person care stood at 75% of pre-pandemic levels by that time. “Our findings suggest that telehealth care for mental health filled a critical need for pediatric patients after the emergence of the COVID-19 pandemic and continues to support a substantial proportion of pediatric mental health care,” said lead author Mariah Kalmin, a policy researcher at RAND, a nonprofit research organization in Santa Monica, Calif. For the study, the researchers examined claims from health benefit manager Castlight Health. The study involved 1.9 million children and teens with commercial insurance from January 2019 through August 2022. Castlight manages insurance plans for about 200 employers in all 50 U.S. states. The researchers looked for common pediatric mental health diagnoses, including anxiety disorders, adjustment disorder, attention-deficit/hyperactivity disorder (ADHD), major depressive disorder and… read on > read on >

Some common medications — including antidepressants, sleep aids and painkillers — may dull the driving skills of seniors, a new study finds. Many different medication classes have been linked to the risk of driving impairment, as anyone who has ever read the label warning “do not operate heavy machinery” might have guessed. But the new study took a particularly rigorous approach to investigating the issue — following older adults for up to 10 years and testing their driving skills with annual road tests. And it turned out that those using certain classes of medications were at greater risk of failing the road test at some point. When older folks were taking either antidepressants, sedative/hypnotics (sleep medications) or non-steroidal anti-inflammatory drugs (NSAIDs), they were nearly three times more likely to get a failing or “marginal” grade than non-users. The findings do not prove the medications are to blame, said lead researcher Dr. David Carr, a specialist in geriatric medicine at Washington University’s School of Medicine in St. Louis. It can be hard, he said, to draw a direct line between a particular medication and diminished driving skills: Is it that drug, or the medical condition it’s treating or another medication an older adult is taking? In this study, though, Carr and his colleagues were able to account for many factors, including participants’ medical conditions, memory and… read on > read on >

Loneliness can leave many feeling desolate, but new research now suggests it may also leave people vulnerable to Parkinson’s disease. Among more than 490,000 people listed in the UK Biobank who were followed for up to 15 years, loneliness appeared to increase the chances of a Parkinson’s diagnosis by 37%. “The association between loneliness and incident Parkinson’s disease was not due to shared genetic, clinical or behavioral risk factors,” said senior researcher Angelina Sutin, a professor in the department of behavioral sciences and social medicine at Florida State University’s College of Medicine in Tallahassee. Although this study can’t prove that loneliness causes Parkinson’s disease, there appears to be a connection, Sutin said. “We show that there is an association between loneliness and the development of Parkinson’s disease, not that loneliness causes Parkinson’s disease,” she stressed. Sutin said that loneliness has been identified as a significant public health concern by the U.S. Surgeon General, the National Academies of Sciences, Engineering and Medicine, and the World Health Organization. “This study adds to the body of evidence for the poor outcomes associated with loneliness, particularly neurodegenerative diseases,” she said. “Loneliness has been associated with Alzheimer’s disease and other types of dementia. The present research indicates that it is a risk factor for Parkinson’s disease as well.” Multiple factors may be linked to why loneliness may raise the risk… read on > read on >
