Social media. The climate crisis. Political polarization. The tumult of a pandemic and online learning. Teens today are dealing with unprecedented stressors, and over the past decade their mental health has been in sustained decline. Levels of anxiety and depression rose after the onset of the COVID-19 pandemic. Compounding the problem is a shortage of mental health providers — for every 100,000 children in the U.S., there are only 14 child and adolescent psychiatrists. In response to this crisis, University of Washington researchers studied whether virtual reality might help reduce stress ...

SPOKANE, Wash. – Despite ChatGPT’s reported ability to pass medical exams, new research indicates it would be unwise to rely on it for some health assessments, such as whether a patient with chest pain needs to be hospitalized.   In a study involving thousands of simulated cases of patients with chest pain, ChatGPT provided inconsistent conclusions, returning different heart risk assessment levels for the exact same patient data. The generative AI system also failed to match the traditional ...

PULLMAN, Wash. -- A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and others. Publishing in the Proceedings of the AAAI Conference on Artificial Intelligence, the interdisciplinary group of Washington State University researchers predict water availability from areas in the West where snow amounts aren’t being physically measured. Comparing ...

A simple blood test could allow doctors to determine whether a person may be at higher risk for stroke or cognitive decline during their lifetime, according to a new UCLA Health study.  The study, published in the journal Stroke, found that measuring concentrations of a network of inflammatory molecules in the blood could allow doctors to calculate a risk score for susceptibility for cerebral small vessel disease – a common cause of stroke and a contributor to cognitive decline found especially among the elderly.   Currently, the only way to determine a person’s risk for cerebral vascular diseases has been ...

WASHINGTON, DC – May 1, 2024 – Three-quarters of Americans feel mental health conditions are identified and treated much worse than physical health issues within the U.S. healthcare system, even as more than 80% perceive a dramatic rise in prevalence of mental health issues in the last five years, according to a new survey from West Health and Gallup released at the start of Mental Health Awareness Month and Older Americans Month. Nearly identical percentages believe mental health is handled either “much” (38%) or “somewhat” worse (37%) than physical health ailments, while 15% say they are dealt with “about the same.” ...

Research Highlights: When adults became angry after remembering past experiences, the function of cells lining the blood vessels was negatively impaired, which may restrict blood flow. Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same change in functioning of the blood vessel lining. Embargoed until 4 a.m. CT/5 a.m. ET Wed., May 1, 2024 DALLAS, May 1, 2024 — A brief episode of anger triggered by remembering past experiences may negatively impact the blood vessels’ ability to relax, which is essential ...

A new species of the Japanese lily known as sukashiyuri has been identified for the first time since 1914 by a research team led by Dr. Seita Watanabe, a specially appointed assistant professor at the Botanical Gardens and the Graduate School of Science at Osaka Metropolitan University. Dr. Watanabe questioned the classification used up to now for sukashiyuri group, which usually has orange flowers. These lilies have high ornamental value, having been exported from Japan for more than two centuries. There have been only four taxonomic groups, but Dr. Watanabe and his team sought evidence to prove that there were ...

Due to a later melatonin onset and increased alertness in the evening, teenagers often find it hard to fall asleep at a time that would allow them to clock up the recommended eight to 10 hours of sleep each night. It is also during teenage years when increasing school demands, activities, more independence from parents, and relationships with peers begin to compete with sleep. The role of social context, however, is often overlooked when studying adolescents’ sleep. Now, researchers in Sweden and Australia wanted to find out how popularity ...

Patients with rheumatoid arthritis (RA) all have a unique and diverse set of antibodies that are involved in the development of the disease. Researchers at Utrecht University unveiled the complexity of these antibodies using powerful lab tools capable of analysing our immune system at molecular levels. Their discovery suggests that current assumptions about the origin of RA are too simple. Still, their findings may point towards improved diagnostics. Rheumatoid arthritis is a chronic autoimmune disease that primarily affects the joints, causing pain, stiffness, and swelling. It arises when the immune system mistakenly attacks the body’s own tissues, leading ...

Considered the most competitive in the world, NBA athletes frequently travel ...

CLEVELAND, Ohio (May 1, 2024)—Musculoskeletal pain is a prevalent menopause symptom, which helps explain why women typically experience more pain than men, especially around the age of 50 years. Beyond pain, muscle function and mass are also affected by menopause. A new study suggests premature surgical menopause can lead to an increased risk of muscle disorders. Results of the survey are published online today in Menopause, the journal of The Menopause Society. The highly publicized Study of Women’s Health Across the Nation spotlighted a number of symptoms that are common during the menopause ...

Women are 40% more likely to experience depression in the perimenopause than those who aren’t experiencing any menopausal symptoms, finds a new study led by UCL researchers. The research, published in the Journal of Affective Disorders, provided a meta-analysis of seven studies involving 9,141 women from across the world (including Australia, USA, China, Netherlands and Switzerland), to understand whether different stages of the menopause were associated with different risk of depression. The perimenopause usually occurs around three to five years before the onset of menopause. During this stage women’s oestrogen and progesterone levels begin to fluctuate, ...
