Transgender youth are more likely than others to experience sleep disorders such as insomnia and sleep apnea, and researchers now recommend these young people be screened for sleep problems. “Transgender and gender-nonconforming identity may precede mental health disorders, and both influence insomnia diagnosis,” said study co-author Galit Levi Dunietz, an epidemiologist in the University of Michigan neurology department’s division of sleep medicine. For the study, the researchers analyzed claims data from more than 1.2 million people aged 12 to 25. Among them were just over 2,600 young people who identified as transgender or gender-nonconforming. The investigators found that transgender youth were 5.4 times more likely than cisgender youth to have insomnia. They were also three times more likely to have sleep apnea or other sleep disorders. (Cisgender means they identify with the gender assigned at birth). The results show a concerning number of individuals with disorders that harm sleep quality, said co-author Dr. Ronald Gavidia, a sleep medicine physician at the university. Other research has suggested that transgender youth and adults also have a high prevalence of depression and anxiety symptoms. These are known to affect sleep quality and health, and they may be contributing to insomnia in this group, the study authors noted. “Given this higher prevalence of sleep disorders in relation to cisgender youth, clinicians should consider screening and testing this population for…  read on >  read on >

Stress affects gut health and intensifies pain, which — for people with irritable bowel syndrome (IBS) — can make traveling to see family during the holiday season excruciating. “People living with IBS often say the holidays are especially stressful, above and beyond the typical holiday stress most people report having,” said Tiffany Taft, medical social scientist and clinical psychologist at Northwestern Medicine, in Chicago. For the 15% of Americans who live with IBS, Taft offered some tips as they gather for the season. “Stress directly affects IBS through the gut-brain axis, which includes parts of the brain that are part of the body’s fight-flight-freeze response,” she said. “Stress can amplify pain, alter the motility of the gut — either speed up or slow down, depending on the person — and change the composition of the gut microbiome.” That can make symptoms more severe. For some, that may mean more frequent trips to the bathroom. For others, it may mean fewer than usual. Symptoms can include increased stomach pain and cramping, bloating and increased urgency to go to the bathroom. Taft said the holidays can create stress because some people have family members who aren’t understanding or supportive about IBS. They may worry or be anxious about asking for changes to the holiday menu because of dietary needs. Rather than have an unpleasant conversation, the person…  read on >  read on >

Millions of Americans will enjoy a hot, nutritious Thanksgiving meal thanks to their local food pantry, often staffed by volunteers. Now, new research spotlights just how important these charities are. Families who rely on pantries for food assistance come away with $600 to $1,000 in free meals and produce every year, after taking into account time, transportation and other costs associated with using them, researchers say. Nationwide, that adds up to big numbers, a new study shows, with pantries collectively providing Americans between $19 billion and $28 billion in free food every year. “The most recent Household Food Security in the United States report … estimates that 5.6% of U.S. households use food pantries, which are the main distribution vehicle for food banks,” said study author Anne Byrne, a Washington, D.C.-based research agricultural economist for the U.S. Department of Agriculture. As a doctoral student at Cornell University in Ithaca, N.Y., Byrne worked with economics professor David Just to determine the net value received by folks seeking food pantry assistance. “We know people receive the food for a retail cost of $0,” Byrne noted. “But by using travel costs — (such as) time, gas, etc. — we were able to estimate what people give up in order to get food from pantries.” On average, their research revealed, every time someone visits a pantry, he or she…  read on >  read on >

The kids aren’t alright. Up to 1 in 5 children in the United States has a mental health condition, but only about half of those who need mental health care are now receiving it. What’s more, suicide is the second leading cause of death among U.S. kids and teens, and youth suicide rates have been rising over the last decade. Now, about one year after the U.S. Surgeon General cited an urgent need to address the crisis, new research shows that the young people who are most likely to die by suicide live in areas with pronounced shortages of mental health professionals. These professionals are also feeling the strain as their workloads and waitlists grow exponentially, according to the American Psychological Association’s 2022 COVID-19 Practitioner Impact Survey. “This is a national emergency, and swift action is needed to improve youth mental health,” said study author Dr. Jennifer Hoffmann, an attending physician in the Division of Emergency Medicine at Ann & Robert H. Lurie Children’s Hospital of Chicago. For the study, she and her colleagues analyzed more than 5,000 suicides by 5- to 19-year-olds that occurred from 2015 to 2016. The rate of suicide increased as the availability of mental health professionals decreased, and this also held for youth suicide by firearms. The greater the professional shortage, the higher the risk for suicide in that area,…  read on >  read on >

Research in wild bats is reinforcing a notion crucial to stopping future pandemics: When wildlife populations stay healthy, the odds of “crossover” viruses infecting humans subsides. In Australia, deforestation has caused a deadly respiratory virus to pass from fruit bats to humans, by forcing the two species into closer contact, a new study reports. Robbed of their winter habitats, large “flying fox” bat populations started breaking up over the past quarter-century and roosting in smaller groups closer to human agricultural and urban areas in subtropical Australia, the study authors explained. These bats are the natural reservoir of Hendra virus, which jumped from the bats into horses and then from horses to humans, according to the report published Nov. 16 in the journal Nature. Hendra virus causes a severe respiratory infection that has proven to be 75% fatal in horses and 57% fatal in humans. The case study offers a glimpse into the process that causes infectious diseases like Ebola to jump from animals into humans, a process called “pathogen spillover,” the researchers noted. “We collected and collated 25 years of data and saw this amazing pattern. We captured this rapid transition from bats feeding in big populations as nomadic animals to bats eking out a living in small populations, in areas where there are people,” said senior researcher Raina Plowright, a professor of public and…  read on >  read on >

With U.S. health officials calling childhood obesity a public health crisis, conversations about weight are important. But what you say to your kids can be challenging, and even counterproductive, a new study found. “Body weight is a sensitive issue and the way we talk about it matters,” said lead author Rebecca Puhl, deputy director of the University of Connecticut Rudd Center for Food Policy and Health. “We really want to identify language that adolescents feel more comfortable using in these conversations, that they don’t feel stigmatized, that they don’t feel blamed or shamed,” Puhl noted. To do that, researchers reviewed 2021survey data from more than 2,000 kids ages 10 to 17, along with more than 1,900 parents. Participants were asked about 27 terms and phrases that can be used to describe body weight. The teens felt the most negative emotions about terms like “overweight,” “fat” and “extremely obese,” the study found. More than one-third of youths reported feeling embarrassment, shame and sadness when their parents used these words. Have a daughter? Tread lightly, the researchers recommended. Girls reported feeling more negative emotions in response to words used about weight than boys did. Whether the young person had obesity or not did not impact how they felt about the words. “I think a lot of parents have positive intentions when it comes to talking about their…  read on >  read on >

Fungi found in the soil are causing lung infections nationwide, even in places that doctors aren’t aware are at risk. The U.S. Centers for Disease Control and Prevention has not revised maps for environmental fungi since 1969, according to a new study that found one disease-causing fungus — histoplasma, or histo — to be more widespread than the old maps show. This can lead to delayed or missed diagnoses in people with lung infections, according to researchers from Washington University School of Medicine in St. Louis. The infections can be confused with COVID-19, bacterial pneumonia or tuberculosis. Fungi become a problem for people when they breathe in spores that are in the soil as the ground is disturbed by farming, landscaping or construction. People can become infected just by walking in areas that have a lot of spores — caves, for example. Infants, older adults and people with compromised immune systems may develop fever, cough, fatigue and other symptoms. “Every few weeks I get a call from a doctor in the Boston area — a different doctor every time — about a case they can’t solve,” said senior author Dr. Andrej Spec, an associate professor of medicine and a specialist in fungal infections at WUSTL. “They always start by saying, ‘We don’t have histo here, but it really kind of looks like histo.’ I say,…  read on >  read on >

It’s sort of like the Goldilocks principle — a room that’s either too dry or too humid can influence transmission of COVID-19 and cause more illness or death, Massachusetts Institute of Technology researchers say. Maintaining an indoor relative humidity between 40% and 60% is associated with lower rates of COVID-19 infections and deaths, they reported Nov. 16 in the Journal of the Royal Society Interface. Indoor conditions outside that range are associated with worse COVID outcomes, according to the report. “There’s potentially a protective effect of this intermediate indoor relative humidity,” said lead author Connor Verheyen, a doctoral student in the Harvard-MIT Program in Health Sciences and Technology, in Cambridge, Mass. The research team noted that most people are comfortable between 30% and 50% relative humidity. An airplane cabin is kept around 20%. Until now, researchers have considered that COVID-19 could be influenced by the seasons, but they tended to examine the virus’ patterns in the context of outdoor weather conditions. The MIT team decided that other researchers might be looking in the wrong direction, given that people in most places spend more than 90% of their time indoors. Indoor conditions also are where most viral transmission occurs. For the study, the investigators combined COVID data with meteorological measurements taken from 121 countries. They gathered COVID case counts and deaths from between January and August…  read on >  read on >

Whether you survive a bout with cancer may depend, in part, on where you live. Researchers at the American Cancer Society and Clemson University in South Carolina found a 20% higher death rate for all cancer types in the communities with the most racial and economic segregation. For lung cancer, the death rate was 50% higher in the most segregated counties. “Many people living in low-income minority households have less access to employment opportunities, transportation, education and health care, and are more likely to experience worse health outcomes,” said senior study author Xuesong Han, scientific director of health services research at the American Cancer Society. “These findings show it is imperative we continue to look for ways to increase access to cancer prevention and early detection wherever possible, to reduce disparities in cancer outcomes,” she said in a society news release. The researchers examined county-level sociodemographic and death rate data from 2015 to 2019 from the U.S. Census Bureau and the National Center for Health Statistics. Among their findings: Residential racial and economic segregation was associated with cancer deaths at the county level. Segregation was associated with higher death rates from 12 of 13 selected cancer sites. Reasons why lung cancer death rates would be most strongly associated with segregation included more exposure to risk factors such as smoking and air pollution and less early…  read on >  read on >

Ayahuasca, a powerful psychoactive drug derived from a South American plant, is a traditional Amazonian-based medicine and an increasingly popular hallucinogenic brew used by devotees worldwide. But what is the ayahuasca experience really like? An international survey of thousands of men and women who have tried the drug for religious, therapeutic or recreational purposes provides some clues. On the downside, the vast majority said the drug induced some significant side effects, ranging from nausea and vomiting to the onset of nightmares, disturbing thoughts and a feeling of disconnection. On the upside, however, only a very small minority said they needed medical care to handle their physical discomfort. And among those reporting psychological disturbances, nearly 9 in 10 said they were just part of an experience they considered beneficial. “Ayahuasca has seen rapid growth in popularity over the last 15 years, via Western tourists heading to South America, and underground facilitated ceremonies being offered in alternative healing and spirituality settings in Western countries,” said study author Daniel Perkins, an associate professor and senior research fellow at the University of Melbourne in Australia. “However, it remains fairly niche.” Generally, ayahuasca is a brownish-red drink with a strong taste and smell. The active drug it contains is considered a Schedule 1 drug in the United States, like heroin, and therefore illegal. In most cases, Perkins said, it’s taken…  read on >  read on >
