COVID-19 and cognitive change in a community-based cohort

JAMA Network Open

2025-06-30

(Press-News.org) About The Study: This cohort study of older participants found accelerated decreases in cognition among individuals hospitalized for SARS-CoV-2 infection, but not nonhospitalized infection, in comparison with individuals not yet infected. These findings suggest that avoiding severe SARS-CoV-2 infection could help preserve cognitive function among older adults.

Intent to test for COVID-19 in the postpandemic era

2025-06-30

About The Study: Nearly one-third of U.S. adults would not or might not test for suspected COVID-19, largely because they do not see value in testing, according to the results of an online national survey. Test hesitancy may delay oral antiviral initiation and could result in missed opportunities to limit transmission. Efforts are needed to increase awareness of the value of testing.

Landmark study investigates potential of Ambroxol, a cough medicine, to slow Parkinson’s-related dementia

2025-06-30

LONDON, Ont. – Dementia poses a major health challenge with no safe, affordable treatments to slow its progression. Researchers at Lawson Research Institute (Lawson), the research arm of St. Joseph’s Health Care London, are investigating whether Ambroxol - a cough medicine used safely for decades in Europe - can slow dementia in people with Parkinson’s disease. Published today in the prestigious JAMA Neurology, this 12-month clinical trial involving 55 participants with Parkinson’s disease dementia (PDD) monitored memory, psychiatric symptoms and GFAP, a blood marker linked to ...

Finding suggests treatment approach for autoimmune diseases

2025-06-30

An engineered protein turns off the kind of immune cells most likely to damage tissue as part of Type-1 diabetes, hepatitis, multiple sclerosis, shows a new study in mice. In these autoimmune diseases, T cells mistakenly target the body’s own tissues instead of invading viruses or bacteria as they would during normal immune responses. Treatments focused on T cells have been elusive because blocking their action broadly weakens the immune system and creates risk for infections and cancer. Published online June 30 in the journal Cell, the study revealed that holding closely together two protein groups (signaling complexes) on ...

A new “link” to triple-negative breast cancer

2025-06-30

Breast cancer is one of the most common cancers among women in the United States. Thanks to decades of fundamental research, it’s also one of the most curable. The exception is a particularly aggressive variant known as triple-negative breast cancer (TNBC). It accounts for 10 to 15 percent of all breast cancer cases. It disproportionately affects younger and African American women. No effective therapies exist. A new discovery by Cold Spring Harbor Laboratory Professor David Spector and graduate student Wenbo Xu—published in Molecular Cancer Research, a journal of the American Association for Cancer Research—could help ...

Cool is cool wherever you are

2025-06-30

From Chile to China, cultures vary greatly around the globe, but people in at least a dozen countries agree about what it means to be cool, according to research published by the American Psychological Association. The researchers conducted experiments with almost 6,000 participants from countries around the world and found that cool people have surprisingly similar personalities. Even though Eastern and Western cultures often differ in many cultural attitudes, cool people were universally perceived to be more extraverted, hedonistic, powerful, adventurous, open and autonomous. “Everyone wants to be cool, or at least ...

Meteorological satellites observe temperatures on Venus

2025-06-30

Imaging data from Japan’s Himawari-8 and -9 meteorological satellites have been successfully used to monitor temporal changes in Venus’ cloud-top temperature, revealing unseen patterns in the temperature structure of various waves. A team led by the University of Tokyo collated infrared images from 2015–25 to estimate brightness temperatures on day to year scales. The results demonstrate that meteorological satellites can serve as additional eyes to access the Venusian atmosphere from space ...

New hope for brain cancer: FAU awarded grants for glioblastoma treatment

2025-06-30

Florida Atlantic University researchers have secured two key grants to investigate targeting a gene for the first time as a new approach to treat glioblastoma, a very aggressive and fast-growing type of brain cancer. Malignant gliomas, such as glioblastoma multiforme and astrocytomas, are the most common type of primary brain tumor in the United States. They make up about 78% of all malignant brain tumors. Although these tumors are not very common, especially in the U.S., they cause a high number of cancer deaths because they are so aggressive. These awards, granted by the Florida Department of Health’s Cancer Connect program for $562,000 and the Palm Health Foundation for ...

Bacteria hijack tick cell defenses to spread disease

2025-06-30

PULLMAN, Wash. – Washington State University researchers have discovered how the bacteria that cause anaplasmosis and Lyme disease hijack cellular processes in ticks to ensure their survival and spread to new hosts, including humans. Based in the College of Veterinary Medicine, the team found that the bacteria can manipulate a protein known as ATF6, which helps cells detect and respond to infection, to support its own growth and survival inside the tick. The findings, published in the journal Proceedings of the National Academy of Sciences, could serve as a launching point for developing methods to eliminate the bacteria in ticks before they are transmitted to humans and ...

New study shows omega-6 does not increase inflammation

2025-06-30

June 30, 2025, Sioux Falls, SD: A new study published in Nutrients offers new insight into omega-6 and whether it is truly the proinflammatory fatty acid many claim it to be. There is currently a heightened interest in the health effects of seed oils, many of which are rich in linoleic acid (LA), an essential omega-6 fatty acid. Many have claimed that western diets contain “too much” LA and that many diseases of modernity stem from the increased intake of LA over the last century. This narrative places the blame on excess inflammation presumably caused by higher LA intakes. But ...
