Tropical cyclones, including hurricanes and tropical storms, are linked to increased rates of drug-related deaths up to three months after the storm passes—particularly in higher-income, White communities and among younger populations. The study of more than 30 years of data by researchers at Columbia University Mailman School of Public Health points to one overlooked health impact of climate change, which is leading to more active and severe storms.
Adults with intellectual and developmental disabilities, such as autism and Down syndrome, experience substantially higher rates of anxiety and depression than the general population of adults, researchers report in JAMA Network Open.
The study, based on data from 44,000 adults, provides the first national estimates of mental health symptom prevalence, healthcare treatment and access barriers facing this population.
"Our findings paint a distressing picture of the mental health and healthcare for people with these disabilities in the United States," said senior author Dr. Dimitri Christakis, a professor of pediatrics at the University of Washington School of Medicine. “Historically, society has not taken the needs of this population as seriously as it should, so in that respect, our findings aren’t surprising. But the scale of burden is shocking.”
In proof-of-concept study, scientists at Cincinnati Children's discover a method to reduce heart damage risk for people with cancer taking immune checkpoint inhibitors.
The protein “neurofilament light chain” (NfL) – studied in humans in the context of neurodegenerative diseases and aging – is also detectable in the blood of numerous animals, and NfL levels increase with age in mice, cats, dogs, and horses. Experts from the DZNE and the Hertie Institute for Clinical Brain Research (HIH) at the University of Tübingen report these findings in the scientific journal “PLOS Biology”. In their view, this biomarker could help to assess the biological age of animals and estimate their life expectancy.
