FDA clears flu and RSV panel as N-MNA repairs intestinal damage in tests
The FDA cleared Molecular Designs' panel for testing influenza A, influenza B and RSV in a single run, and Rutgers Health researchers reported that N-MNA rapidly repairs intestinal lining in mice, flies and human cells. A randomized trial also found that common ADHD classroom accommodations did not significantly improve behavior or academic performance.
FDA clears Molecular Designs panel for flu A, flu B and RSV
The U.S. Food and Drug Administration granted 510(k) clearance to Molecular Designs' SimplicityDx Panel FluA/FluB/RSV, the company's first FDA-cleared assay. The multiplex real-time RT-PCR test detects and differentiates influenza A, influenza B and RSV RNA in anterior nasal swabs from people with respiratory symptoms. The single-run panel can help laboratories manage simultaneous flu and RSV circulation during respiratory season.
NIH award supports research on gut protist Blastocystis
Georgia Tech assistant professor Abigail Lind has received a five-year NIH award to study Blastocystis, a common gut protist overlooked because research has focused mainly on bacteria. The organisms are now linked to positive health markers, but little is known about their role. Her team has developed lab techniques to cultivate the protist and study its diet and interactions with gut microbes.
Bacterial molecule N-MNA rapidly repairs intestinal damage in tests
Rutgers Health researchers found that N-MNA, a molecule produced by some gut bacteria, rapidly repairs the intestinal lining in mice, flies and human cells. In tests, N-MNA activated NAD, a coenzyme whose decline is linked to aging, and stimulated stem cell regeneration. The molecule supplied about 22 percent of NAD in human colon cells within 24 hours.
Native American and Hispanic women diagnosed with endometrial cancer earlier
A University of Arizona study found Native American and Hispanic women were diagnosed with endometrial cancer at younger ages than White and non-Hispanic women. In records of 168 women with cancer, Native American patients had an average diagnosis age of 49.8 years and Hispanic patients 53.7 years, compared with 62 years for White patients and 61.6 years for non-Hispanic patients. The results challenge the view that it mainly affects older women.
Common ADHD classroom accommodations show no significant benefit
A Florida International University randomized trial found that extended time, frequent breaks, standing at a desk and low-distraction settings did not significantly improve classroom behavior or academic performance for children with ADHD. The study, published in JAMA Pediatrics, involved 255 children in kindergarten through sixth grade, of whom 235 completed it. The findings question common accommodations in IEPs and Section 504 plans.
Mount Sinai maps enzyme target for rare glutaric aciduria
Mount Sinai researchers mapped the human AASS enzyme, which breaks down lysine, and identified a flexible region that regulates its activity. The Science Advances study provides structural details that could guide drugs to inhibit AASS and reduce harmful metabolite buildup in glutaric aciduria type 1. The rare inherited disorder can cause toxic substances to accumulate and lead to irreversible brain damage.
Early-life environmental exposures linked to multiple health outcomes
A study led by the Barcelona Institute for Global Health and Inserm found that early-life environmental exposures can be associated with multiple health outcomes at the same time, with many persisting into adolescence. Published in Science Advances as part of the HELIX project, it analyzed 69 prenatal and 129 childhood exposures with 11 health outcomes from ages 6 to 18. Six prenatal and 42 childhood exposures were linked to multiple outcomes.
Mouse brain map offers clues to coordinated body movements
Researchers at Columbia's Zuckerman Mind Brain Behavior Institute published a new map of how a mouse's body is represented in its motor cortex. Using high-speed wide-field optical imaging, they analyzed neural activity while mice moved and found that apparently random activity during rest was also revealing. The map may help explain dexterous movements that can be lost after brain injuries such as strokes.
Two proteins may link plant toxin to pulmonary hypertension
A study by Yisheng He's team at The Chinese University of Hong Kong found that a reactive monocrotaline metabolite modified the platelet prostacyclin receptor and lung PTEN in rats. The changes were associated with sustained platelet activation and thickening of pulmonary artery walls, raising right ventricle pressure. The proteins offer potential molecular targets for toxin-associated pulmonary arterial hypertension.
Low testosterone linked to 18% higher cancer death risk in men
A systematic review in Lancet Healthy Longevity analyzed long-term data from more than 26,000 men in Australia, the United States and Europe. Men in the lowest fifth of testosterone levels had an 18 percent higher relative risk of dying from any cancer than men in the highest fifth, after allowing for age and other health factors. Especially low levels may be a marker of poor health.
