Nancy A. Melville October 21, 2022 MONTREAL — Amid common patient concerns about weight gain in the treatment of hyperthyroidism, findings from a large study suggest the therapy with the most favorable survival rate — radioiodine — is not associated with an increased risk of weight gain or obesity. “EGRET is the first large study using population-based...

Two Exercise Interventions May Ease Acute, Subacute Spine Pain
Megan Brooks December 28, 2022 Two conservative interventions are effective for treating acute and subacute spine pain, new research suggests. Results from the SPINE CARE randomized controlled trial showed that 6–8 weeks of an individualized postural therapy (IPT) or a multidisciplinary biopsychosocial intervention known as ICE that includes physical therapy were associated with small but statistically significant...

DNA fragments in blood promise cheap, easy test for cancer
by Amy Norton Researchers are reporting progress on a blood test that can detect multiple cancers in a relatively simpler, and potentially less pricey way than other tests under development. The test picks up certain cancer signals in the blood using a fairly straightforward method: counting bits of DNA that appear to be “broken” in unexpected...

Scientists find way to heal scars left behind by heart attacks
by University of Sydney Credit: Circulation Research (2022). DOI: 10.1161/CIRCRESAHA.122.321123 After a heart attack, the shock of the event leaves behind a trail of damaged heart muscle, which becomes a scar over time. However, the scar tissue doesn’t have the elasticity and flexibility of healthy heart muscle, meaning there can be complications with pumping and transporting blood. For...

A simple smell test may help reveal signs of unhealthy aging and frailty
JANUARY 12, 2023 by Shyla Cadogan (Credit: RODNAE Productions from Pexels) BALTIMORE — A simple smell test could help doctors screen older adults for signs of frailty and unhealthy aging. Researchers from Johns Hopkins demonstrated that the loss of smell may be predictive of a higher risk for age-related health problems. So far, studies have shown that smell...

Alzheimer’s study controversy: What does it mean for future research?
A now-seminal study published in 2006 provided evidence that the toxic accumulation of a protein called beta-amyloid in the brain was tied to the development of Alzheimer’s disease. Recently, an assistant professor from Vanderbilt University suggested that some of the images in this study were manipulated by the authors. What does all of this mean?...
