Left atrial appendage closure matches anticoagulants in AFib patients

For patients with non-valvular atrial fibrillation (AFib) who had no contraindications to taking oral anticoagulants, the use of a device to close off the left atrial appendage in the heart—a small pouch where blood can pool and form dangerous clots—was comparable to standard medication therapy in reducing the combined rate of all-cause stroke, cardiovascular death and systemic embolism at three years.

Heart structure changes in midlife linked to long-term disease risk

Higher left atrial end-systolic dimension (LASD), an increased measurement of the left upper chamber of the heart, and left ventricular mass (LVM), a clinical measurement of the weight of the heart's left ventricular myocardium, are well-established indicators of cardiovascular damage that are associated with a higher risk of cardiovascular disease (CVD) in the short-term (less than 10 years).

Study reveals immune changes in HIV and HCV coinfected patients

Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection leads to severe systemic inflammation, increasing non-AIDS morbidity and mortality risk. CD39 ectoenzyme on T-cells, which catalyzes the conversion of pro-inflammatory purines to immunosuppressive adenosine, plays an important role in inflammation control.

Ultrasound advances offer noninvasive assessment of portal hypertension severity

Portal hypertension (PH), a serious complication of liver cirrhosis, is defined as a pressure gradient > 5 mmHg between the portal vein and the inferior vena cava.

$Heart health linked to higher fracture risk in postmenopausal women$

Heart health linked to higher fracture risk in postmenopausal women

Postmenopausal women face a high risk of bone fractures. Due to declines in estrogen levels, which can lead to an increased risk of osteoporosis, even a low-impact fall can result in a serious hip, back or wrist injury.

New mother’s experience highlights importance of postpartum heart care

At 35, Brooklyn resident Luyba Caloras was healthy, with no history of heart problems and no reason to think she was at risk of them. But pregnancy can act as a stress test on the heart—and soon after delivering her son at NYU Langone Health on February 3, 2024, she was diagnosed with a complication she never expected.

HOBIT device improves oxygen supply for drug-producing cells

Implanting living cells as long-term drug producers could transform treatment for numerous diseases, but it is difficult to house the tiny workers in quantities high enough to ensure dosage needs are met while also keeping the cells alive and thriving.

Tiny device with engineered cells acts as internal drug factory

A multi-institutional team of scientists, co-led by Northwestern University, has taken a crucial step toward implantable "living pharmacies" - tiny devices containing engineered cells that continuously produce medicines inside the body.

Drugs targeting TIE2 protein could help prevent formation of cerebral cavernous malformations

Researchers in the Perelman School of Medicine at the University of Pennsylvania have identified a cell surface receptor protein called TIE2 as the missing link between two key signaling pathways that drive the growth of blood vessel abnormalities known as cerebral cavernous malformations (CCMs).

Machine learning model predicts liver cancer risk with high accuracy

A machine learning model that analyzes patient demographics, electronic health record data, and routine blood test results predicted a patient's risk of hepatocellular carcinoma (HCC), the most common type of liver cancer, with high accuracy.

GLP-1 medications show mixed effects on body contouring outcomes

For patients undergoing body contouring surgery to remove excess abdominal skin after massive weight loss, use of GLP-1 weight-loss medications may have mixed effects on complication risks, suggests a study in the April issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons.

Heart failure and atrial fibrillation share underlying genetic and molecular mechanisms

New research published in Nature Cardiovascular Research reveals that heart failure and atrial fibrillation share underlying genetic and molecular mechanisms, suggesting that the two cardiovascular conditions may be less distinct than previously thought.

ATLAS platform enables realistic study of metastatic cancer clusters

Metastasis, the spread of cancer from a primary tumor to other parts of the body, is difficult to study in the lab, in part because researchers lack reliable ways to recreate the conditions cancer cells encounter as they travel through the bloodstream.
