Prickly pear may pack a surprising punch against metabolic syndrome

This narrative review examines how Opuntia ficus-indica fruit, or prickly pear, may help target multiple features of metabolic syndrome through its fiber, betalains, polyphenols, carotenoids, and other bioactive compounds. The authors conclude that the fruit shows promising mechanistic and preclinical potential, but stronger human trials are still needed before firm clinical claims can be made.

New dual drugs eliminate tumors when combined with immunotherapy

Researchers at Johns Hopkins University and the University of Maryland School of Pharmacy have developed a set of novel, first-in-class drugs that inhibit hypoxia-inducible factors 1 and 2, a pair of transcription factors considered to be "master regulators" of cancer progression.

Treating autonomic dysfunction can relieve symptoms of treatment-resistant depression

Consider a house with the water main half shut. The faucets sputter. The toilet runs all night. The garden wilts. You could call a plumber for the faucet, a landscaper for the garden, a different plumber for the toilet, and every one of them would fix something while fixing nothing.

NOX-1 identified as key molecular target to prolong ketamine's antidepressant effects

Treatment-resistant depression affects a large proportion of people with major depressive disorder, and while ketamine offers rapid relief, its antidepressant effects fade within a few weeks.

Short bursts of vigorous activity can lower risk of major diseases

People who get just a few minutes of vigorous activity daily are less likely to develop eight major diseases, including arthritis, heart disease and dementia, according to research published in the European Heart Journal today (Monday).

Trial shows mavacamten benefits adolescents with obstructive heart condition

Adolescent patients with obstructive hypertrophic cardiomyopathy (HCM) who received the drug mavacamten saw a significant improvement in left ventricular outflow tract (LVOT) gradient, a measure of blood flow obstruction in the heart, compared with those who received a placebo, according to a small study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Left-ventricular unloading during angioplasty fails to improve patient outcomes

The first randomized trial to compare standard percutaneous coronary intervention (PCI), also known as coronary angioplasty, with PCI accompanied by the use of a temporary, miniaturized pump to support the heart in patients with both severe coronary heart disease and moderate to severe heart failure found no significant difference between the two approaches.

Microaxial flow pump fails to reduce heart damage in STEMI trial

Using a microaxial flow pump prior to and during cardiac stenting procedures for patients with severe heart attacks who don't have cardiogenic shock does not significantly reduce heart damage.

Catheter-based approach improves prognosis in pulmonary embolism patients

Patients who had low doses of clot-buster drugs delivered directly to the site of a pulmonary embolism (PE) via a catheter using ultrasound to enhance their effect had significantly better outcomes than those who received standard systemic anticoagulants, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Temporary heart pump before PCI shows no significant benefit

The first randomized trial to test whether adding a small, temporary pump to allow the heart to rest and intentionally delaying percutaneous coronary intervention (PCI), also known as coronary angioplasty, for 30 minutes to reduce heart damage compared with standard immediate PCI in patients with heart attacks at risk for a large amount of heart damage found no significant difference between the two groups, the study's primary endpoint. The research was presented at the American College of Cardiology's Annual Scientific Session (ACC.26).
