Both the new weight loss drugs and bariatric (weight loss) surgery improve body composition in patients with obesity by inducing a moderate loss of fat-free mass (including lean muscle) along with a substantial reduction in fat, researchers at Vanderbilt Health have found.
Scientists at the Icahn School of Medicine at Mount Sinai, in partnership with the Multiple Myeloma Research Foundation (MMRF) and in collaboration with leading institutions across the country, have helped generate the largest single-cell immune cell atlas of the bone marrow in patients with multiple myeloma, a blood cancer that, while treatable, remains incurable. The findings, published in Nature Cancer, provide unprecedented insight on immune dysfunction in myeloma and could lead to improved tools for predicting which patients are at higher risk of relapse after treatment.
