Study finds gut microbes adapt quickly to changes in food preparation

How we prepare food matters to us, surprisingly deeply, it turns out. Scientists have recently discovered that different diets—say, high-fat versus low-fat, or plant-based versus animal-based—can rapidly and reproducibly alter the composition and activity of the gut microbiome, where differences in the composition and activity can affect everything from metabolism Continue Reading

Study finds early life racial discrimination linked to depression, accelerated aging for African Americans

Early life stress from racial discrimination puts African Americans at greater risk for accelerated aging, a marker for premature development of serious health problems and perhaps a shorter life expectancy, according to a study led by a Georgia State University psychology researcher. Sierra Carter, an assistant professor of psychology at Continue Reading

Study finds potential therapeutic target for prostate cancers with PTEN mutation

PTEN, a tumor suppressor gene mutated in approximately 20% of primary prostate cancers, and in as many as 50% of androgen deprivation-resistant prostate cancers, relies on another gene, ARID4B, to function. These findings were published by George Washington University (GW) Cancer Center researchers in Nature Communications. This discovery provides a Continue Reading

Older adults with COPD more likely to use synthetic cannabinoids, study finds

A study published today in Drugs & Aging found that older adults in Ontario with chronic obstructive pulmonary disease (COPD) were twice as likely to use prescription synthetic oral cannabinoids compared to older adults without COPD. Using provincial health administrative databases, researchers found that while synthetic oral cannabinoid use was Continue Reading

Half of content in physicians’ notes may be inaccurate, study finds

An examination of how closely emergency department doctors’ medical documentation aligned with the actual care they provided to patients found that half the content in the notes that go into the patient’s electronic medical records was inaccurate. The researchers initiated the study after noticing that many physicians were writing extensive Continue Reading

Study finds new way to make chemotherapy more effective against pancreatic cancer

Pancreatic adenocarcinoma (PDAC) is a lethal malignancy that most often is resistant to chemotherapy. Researchers have been searching for ways to increase the sensitivity of the tumors to cancer-fighting drugs. A Mayo Clinic-led study published today opens a promising new front in that battle. Using patient cell lines and tumor-bearing Continue Reading
