Mount Sinai Study Calls for Major Changes in the Way People With Comorbidities Are Selected by Physicians for Lung Cancer Screening

A Medicare policy requiring primary care providers (PCPs) to share in the decision-making with patients on whether to proceed with lung cancer screening is fraught with confusion and lack of evidence-based information, and may actually be undermining the purpose for which it was created, Mount Sinai researchers say.

UTSW researcher receives NIH Director’s New Innovator Award

Ravikanth Maddipati, M.D., Assistant Professor of Internal Medicine and in Children’s Medical Center Research Institute at UT Southwestern, has been awarded $1.5 million from the National Institutes of Health (NIH) to support research investigating positional heterogeneity in cancer, or how tumors in the same organ can behave differently based on where they form.

UTSW researchers identify driver of inflammatory bowel disease

Researchers at UT Southwestern Medical Center have discovered an intracellular mechanism that converts protective intestinal cells into disease-driving pathogenic cells, a finding that could lead to improved treatments for patients with inflammatory bowel disease (IBD).

Fish oil supplement claims often vague, not supported by data

Your daily dose of omega-3s may not be doing what you think it is. Most fish oil supplements on the market today have labels boasting health benefits that aren’t supported by clinical data, according to a study published in JAMA Cardiology by researchers at UT Southwestern Medical Center.

College students help aging patients who are hospitalized

Valentina Harmjanz often tapped into music on her smartphone to connect with older patients she visited at William P. Clements Jr. University Hospital. The UT Southwestern medical student met with patients as part of the Hospital Elder Life Program (HELP), a joint effort between UTSW and the Hobson Wildenthal Honors College at the University of Texas at Dallas.

Gene that regulates immune activity in the retina identified

UT Southwestern Medical Center researchers have identified a gene called Lipe that appears to be pivotal to retinal health, with mutations spurring immune activation and retinal degeneration. This is important because the retina is responsible for detecting the light that is transformed into vision. The findings, published in Communications Biology, provide clues about the mechanisms behind a variety of disorders affecting the retina, including macular degeneration and diabetic retinopathy.

Warfarin use should not disqualify stroke patients from lifesaving clot-removing surgery

Most stroke patients taking the anticoagulant warfarin were no more likely than those not on the medication to experience a brain bleed when undergoing a procedure to remove a blood clot, UT Southwestern Medical Center researchers report in a new study. The findings, published in JAMA, could help doctors better gauge the risk of endovascular thrombectomy (EVT), potentially expanding the pool of eligible patients for this mainstay stroke treatment.

Start screenings at age 45 to prevent colorectal cancer, UT Southwestern experts advise

Colorectal cancer is on the rise among younger adults. According to the American Cancer Society, the proportion of cases among people under 55 increased from 11% in 1995 to 20% in 2019, and it is now the leading cause of cancer-related deaths for men younger than 50.

Poor sleep can lead to long-term health problems for older adults, UTSW specialists say

It’s a common misconception that older adults need less sleep than those younger, but many get fewer hours due to insomnia and various health problems, including sleep apnea and heart trouble. In addition to a reduced quality of life, long-term health consequences of poor sleep include high blood pressure, weight gain, stroke, heart attack, diabetes, memory problems, and even increased risk of death, said Deborah Freeland, M.D., Assistant Professor of Internal Medicine and a member of UTSW’s Division of Geriatric Medicine.

UT Southwestern nephrologist addresses National Kidney Foundation

Susan Hedayati, M.D., Director of Clinical and Population Health Research in Nephrology at UT Southwestern, has spent a career investigating the links between kidney disease and depression and developing methods to improve care from a patient-centric perspective for those with chronic kidney disease.

Autoantibody linked to rare disorder that destroys fat, UT Southwestern researchers find

Researchers at UT Southwestern Medical Center have discovered the first molecular biomarker for acquired generalized lipodystrophy (AGL), a rare disorder in which fat deposits are destroyed, causing patients to have dangerously low body fat, signs of accelerated aging, and severe metabolic diseases including diabetes and fatty liver.

Potential genetic regulators of the heartbeat identified by UT Southwestern researchers

UT Southwestern Medical Center researchers have mapped gene control elements in specialized cardiac cells responsible for coordinating heartbeats. The findings of the genome exploration study, published in The Journal of Clinical Investigation, provide insight into how heartbeats are regulated and could impact diagnosis and risk prediction for a variety of common arrhythmias.
