A single, one-hour treatment that involves breathing in a mixture of oxygen and nitrous oxide — otherwise known as laughing gas — significantly improved symptoms in people with treatment-resistant depression, according to new data from researchers at Washington University School of Medicine in St. Louis and the University of Chicago. In a phase 2 clinical […]
The first evidence of a genetic link explaining why some people who catch Covid-19 don’t become sick has been discovered. A scientific and medical team led by Newcastle University, UK, have demonstrated that the gene, HLA-DRB1*04:01, is found three times as often in people who are asymptomatic. This suggests that people with this gene have […]
New research from Flinders University indicates people with near-sightedness or myopia are more likely to experience poorer sleep quality than people with normal vision. The study, led by optometrist Dr Ranjay Chakraborty from the Flinders Caring Futures Institute, indicates that people with short-sightedness have more delayed circadian rhythms and lower production of melatonin, a hormone […]
A new study shows that tai chi mirrors the beneficial effects of conventional exercise by reducing waist circumference in middle-aged and older adults with central obesity. The study was done by investigators at the University of Hong Kong, The Chinese University of Hong Kong; Chinese Academy of Sciences; and UCLA. JOURNAL: Annals of Internal Medicine […]
Waking up just one hour earlier could reduce a person’s risk of major depression by 23%, suggests a sweeping new genetic study published May 26 in the journal JAMA Psychiatry. The study of 840,000 people, by researchers at University of Colorado Boulder and the Broad Institute of MIT and Harvard, represents some of the strongest […]
While previous research early in the pandemic suggested that vitamin D cuts the risk of contracting COVID-19, a new study from McGill University finds there is no genetic evidence that the vitamin works as a protective measure against the coronavirus. To assess the relationship between vitamin D levels and COVID-19 susceptibility and severity, the researchers […]
A comprehensive analysis of 437 studies from around the world provides the best evidence to date that narcissism is an important risk factor for both aggression and violence, researchers said. The link between narcissism and aggression was found for all dimensions of narcissism and for a variety of types of aggression. Results were similar regardless […]
For many diseases, overweight and obesity are risk factors. But now a study shows that a higher BMI may be linked to higher survival rates in patients hospitalized for severe bacterial infections. The population-based study involved observations, over a nine-month period, of all 2,196 individual adults receiving care for suspected severe bacterial infection at Skaraborg […]
Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body’s immunity changes over time. Scientists at the University of […]
Scientists at the University of York have made significant progress in the development of a nasal spray treatment for patients with Parkinson’s disease. Researchers have developed a new gel that can adhere to tissue inside the nose alongside the drug levodopa, helping deliver treatment directly to the brain. Levodopa is converted to dopamine in the […]
