Cats have a long history of boosting people’s moods and brightening their days. And that’s probably true for kids on the autism spectrum as well, new research shows. The small study suggests that adopting a shelter cat may help reduce separation anxiety and improve empathy in kids with an autism spectrum disorder (ASD). “Cats, and companion animals in general, offer unconditional acceptance and someone to talk to that listens, and caring for an animal can help with learning responsibility,” said study author Gretchen Carlisle. She’s a research scientist at the Research Center for Human-Animal Interaction at the University of Missouri, in Columbia. ASD is a brain disorder that affects social skills, communication and impulse control. In the United States, it affects one child in 54, according to the U.S. Centers for Disease Control and Prevention. The new study included 11 families that had children with autism between the ages of 6 and 14. The families were followed for 18 weeks after adopting a shelter cat. The researchers used standardized social skills and anxiety scales to pick children who were likely to respond well to a pet. The cats were also screened for temperament. Overall, parents reported an instant bond between child and cat, and the bond remained strong over time even with the added responsibility of caring for the pet. The researchers found that the…  read on >  read on >

Delicious but deadly: Eating fried food is tied to an increased risk of heart disease and stroke, a new study suggests. The risk rises with each additional 4-ounce serving per week, a research team in China found. For the study, the investigators analyzed 19 previously published studies. They combined data from 17 studies, involving more than 560,000 people with nearly 37,000 major cardiovascular events, such as heart attack or stroke. The researchers also used data from six studies, involving more than 750,000 participants and nearly 86,000 deaths over an average of 10 years. The study findings showed that compared with those who ate the lowest amount of fried food per week, those who ate the most had a 28% greater risk of major cardiovascular events, a 22% higher risk of heart disease and a 37% higher risk of heart failure. These risks substantially increased by 3%, 2% and 12%, respectively, with each additional 4-ounce weekly serving, according to Pei Qin, of Shenzhen University Health Science Center, in Guangdong, China, and colleagues. The report was published online Jan. 19 in the journal Heart. How fried foods might increase the development of cardiovascular disease isn’t clear, but several explanations are possible, the study authors noted in a journal news release. Fried foods contain harmful trans fatty acids from the hydrogenated vegetable oils often used to cook them,…  read on >  read on >

A promising step toward using retinal cell transplants to treat blindness is reported in a new study. Adult retinal stem cells from deceased human donors survived when they were transplanted into the eyes of non-human primates, according to the researchers. The cells were taken from the retinal pigment epithelium (RPE). It is a layer of cells that supports and nourishes the retina, the light-sensitive tissue that lines the back of the eye. It helps maintain normal vision. RPE dysfunction can result in disorders such as macular degeneration and can cause blindness, which affects about 200 million people worldwide. “The results of this study suggest human adult donor RPE is safe to transplant, strengthening the argument for human clinical trials for treating retina disease,” said co-lead investigator Timothy Blenkinsop. He’s an assistant professor of cell, developmental and regenerative biology at the Icahn School of Medicine at Mount Sinai, in New York City. For the study, his team transplanted cell-derived patches under the primates’ maculas. The transplants remained stable and integrated for at least three months with no serious side effects, such as being attacked by the immune system or light sensitivity, according to the report published Jan. 14 in the journal Stem Cell Reports. The stem cell-derived RPE assumed some of the function of the original RPE, and also supported a photoreceptor that helps with functions…  read on >  read on >

Marijuana addiction increases the risk of death by suicide, homicide and other causes (such as car crashes) in youth and young adults with mood disorders such as bipolar disorder, a new study warns. For the study, the researchers reviewed data on nearly 205,000 young people, aged 10 to 24, in Ohio who were diagnosed with mood disorders from July 2010 through December 2017. Marijuana addiction (“cannabis use disorder”) was reported in more than 10% of people in the study. It was most common among those who were older, male, Black, and those with bipolar or other mood disorders, and a prior history of self-harm and previous mental health service use, including psychiatric hospitalization and emergency department visits. “We also found that cannabis use disorder was significantly associated with self-harm, including death by unintentional overdose and homicide,” said study author Cynthia Fontanella, who stressed however that hte study couldn’t prove cause and effect. Fontanella is an associate professor in the department of psychiatry and behavioral health at Ohio State University, in Columbus. “Marijuana use and addiction is common among youth and young adults with mood disorders, but the association of this behavior with self-harm, suicide and overall mortality risk is poorly understood in this already vulnerable population,” Fontanella said in a university news release. “These findings should be considered as states contemplate legalizing medical and recreational…  read on >  read on >

Want to get the most out of your COVID-19 vaccine? Make sure you get some good rest before you get your shot, sleep experts say. That’s because adequate sleep is an important factor in a strong immune system. “As COVID-19 vaccines are being distributed, it is of utmost importance that patients continue to prioritize their sleep to maintain optimal health,” American Academy of Sleep Medicine (AASM) president Dr. Kannan Ramar said in an academy news release. “Getting sufficient, high-quality sleep on a regular basis strengthens your body’s immune system and optimizes your response to a vaccine.” Several studies have found an association between sleep and vaccination response. For example, a 2020 study in the International Journal of Behavioral Medicine found that flu vaccines appear to be more effective in people who get a sufficient amount of sleep during the two nights prior to receiving the shot. Other studies have reported similar findings about patients’ response to vaccines for hepatitis A and hepatitis B. Dr. Khurshid Khurshid is director of the UMMHC/UMMS Center for Neuromodulation at the University of Massachusetts Medical School, in Westborough, Mass. He said, “The role of sleep in boosting innate and acquired immune response is significant. All people, particularly health workers, should be aware of the immunity-boosting effects of sleep. Studies have shown that normal sleep after vaccination strengthens the immune response…  read on >  read on >

Be kind to your heart and health and turn off the news, doctors say. Northwestern University experts suggest checking in on current events a couple of times a day and no more. Constant updates can fuel anxiety and depression, they warn. “As a practicing preventive cardiologist, one of the most common risk factors for heart disease that I am seeing this year is stress,” said Dr. Sadiya Khan, assistant professor of cardiology and epidemiology at Northwestern University Feinberg School of Medicine in Chicago. “I know we can all agree it has been an extremely stressful year for all in every aspect of our lives, including stress related to the pandemic and associated health, financial and political events.” Constant news updates pile on layer upon layer of stress, according to Dr. Aderonke Pederson, a psychiatrist at Northwestern Medicine. “That cumulative stress can translate into increased risks of heart problems, diabetes and more,” she said. “Mental illnesses like depression and anxiety, especially when untreated, can increase your risk for chronic health conditions like diabetes, cardiac events and heart disease and can complicate symptoms of asthma. So, there’s a feedback loop of mental health conditions and physical health conditions.” The doctors offered several coping strategies, including getting a good night’s sleep and calming your mind a couple hours before bedtime with a light-hearted book, journaling, playing a game…  read on >  read on >

When the coronavirus pandemic began, one U.S. children’s hospital saw an increase in trauma cases from recreational and outdoor activities, even as total ER visits dropped by 50%, researchers report. What happened? Their new study suggests that being in lockdown, with schools closed, may have prompted more kids to go outside and play — and potentially get injured doing so. At the same time, parents may have feared taking their children to the hospital unless it was a dire injury. Study author Dr. Zaid Haddadin, a postdoctoral research fellow at Vanderbilt University Medical Center in Nashville, and his colleagues looked at the number of emergency room visits for respiratory illnesses or trauma between March and May 2020. Over that time, a total of nearly 6,400 pediatric emergency room visits occurred in 2020, compared with more than 12,000 in 2019. Meanwhile, the number of respiratory care for kids visits dropped by 58% in 2020, the researchers found. “Community efforts to control the spread of the SARS-CoV-2 might have played a role in decreasing the spread of other respiratory viruses in children,” Haddadin explained. But at the same time, there was a significant increase in the number of trauma visits related to activities like all-terrain vehicles (ATVs) and motorcycles, which might have been related to school closings, Haddadin said. “Most schools were closed starting mid-March in our…  read on >  read on >

Despite being locked down during the pandemic, child care responsibilities often fell on women’s shoulders, a new study shows. “Most people have never undergone anything like this before, where all of a sudden they can’t rely on their normal child care, and most people’s work situation has changed, too,” said researcher Kristen Shockley, an associate professor of psychology at the University of Georgia. “We thought this would be a chance for men to step in and partake equally in child care, but for many couples we didn’t see that happen.” In mid-March, as schools and day care centers shut down, Shockley’s team surveyed couples, both of whom worked and had at least one child under the age of 6. The team researchers first surveyed 274 couples and followed up with 133 of the same couples in May. “When the wife does it all, not surprisingly, the outcomes are bad for the couple,” Shockley said in a university news release. “It’s not just bad for the wife, it’s also bad for the husband, including in terms of job performance although his work role presumably hasn’t changed. When one person’s doing it all, there’s a lot of tension in the relationship, and it’s probably spilling over into the husband’s ability to focus at work.” Although about 37% of couples relied on the wife to provide most or…  read on >  read on >

A study that examined how people walked through doorways provides new insight into anorexia’s effect on a person’s body image. It’s long been known that people with anorexia overestimate their body size, but this study examined unconscious body awareness — formally called “body schema.” It’s the innate ability a person has to orient themselves in a room and stop from bumping into objects. Body schema usually adapts to wherever a person happens to be,. but the new study found that it might not be as adaptable in people with anorexia. The researchers, at Ruhr University Bochum, in Germany, conducted an experiment with 23 people with anorexia and a control group of 23 people without the eating disorder. The participants were asked to pass through door frames of different widths, but weren’t told that was the actual focus of the study. “The [door] opening was adapted to the shoulder width of the subjects and varied between 0.9 times and 1.45 times this width,” said study leader Martin Diers, a research professor of neuroscience. Participants with anorexia turned their shoulders to the side with much wider doors than those in the control group, according to the report published online recently in the International Journal of Eating Disorders. Lead author Nina Beckmann said, “This shows us that they also unconsciously assess their proportions to be larger than they…  read on >  read on >

Do you you keep 6 feet apart from others to help stop coronavirus spread? New research shows that the wealthier you were at the start of the pandemic, the more likely it is you’ll maintain social distance. The new study looked at social distancing and mask wearing, and determined a link between those behaviors and income. “We need to understand these differences because we can wring our hands, and we can blame and shame, but in a way it doesn’t matter,” said study author Nick Papageorge, the Broadus Mitchell Associate Professor of Economics at Johns Hopkins University in Baltimore. “Policymakers just need to recognize who is going to socially distance, for how long, why and under what circumstances to give us accurate predictions of how the disease will spread and help us establish policies that will be useful,” he said in a Hopkins news release. The research was part of a six-country survey. In the United States, 1,000 people from Texas, Florida, California and New York were asked questions last April about demographic information and their behavior as COVID-19 cases were spiking. People with the highest incomes made the most changes. They were 32% more likely to increase social distancing, 30% more likely to increase hand-washing and mask wearing and 13% more likely to change behaviors. The ability to work from home and having access…  read on >  read on >
