Weight loss drugs and bariatric surgery improve the body’s fat ‘balance:’ study

Vanderbilt University Medical Center
Peer-Reviewed Publication

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.

Body composition changes after bariatric surgery or treatment with GLP-1 receptor agonists

JAMA Network
Peer-Reviewed Publication

About The Study: In this single-center cohort study, both bariatric surgery and semaglutide or tirzepatide treatment were associated with substantial fat mass loss, moderate fat-free mass (FFM) loss, and improved FFM to fat mass ratio. These findings provide evidence to guide interventions aimed at preserving FFM while promoting fat loss.

Targeted regulation of abortion providers laws and pregnancies conceived through fertility treatment

JAMA Network
Peer-Reviewed Publication

About The Study: The findings of this study suggest an increase in maternal morbidity among patients using fertility care in states that passed targeted regulation of abortion providers (TRAP) laws relative to states that did not.

Mount Sinai researchers help create largest immune cell atlas of bone marrow in multiple myeloma patients

The Mount Sinai Hospital / Mount Sinai School of Medicine
Peer-Reviewed Publication

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.

Understanding sex-based differences and the role of bone morphogenetic protein signaling in Alzheimer’s disease

Waseda University
Peer-Reviewed Publication

Alzheimer’s disease (AD) is a serious neurodegenerative disease largely affecting older adults. Apart from age, it also shows sex-based differences, with women being more at risk. However, the origin of these differences remains unknown. While bone morphogenetic proteins (BMPs) play an important role in adult neurogenesis, their role in AD remains elusive. To address this, researchers have investigated sex-based differences and role of BMP signaling in neurogenesis in AD mice models, uncovering novel therapeutic targets
