Better sleep, BMI, and glucose control lower female infertility odds

A new study using NHANES data found that higher Life’s Crucial 9 (LC9) scores, reflecting better cardiovascular and mental health, were linked to lower odds of female infertility. However, adding depression to the LE8 framework did not significantly improve its predictive value.

Gut microbiome pattern predicts future heart attack risk in coronary heart disease patients

A specific gut microbiota pattern was found to predict new cardiovascular events in patients with coronary heart disease, based on data from the CORDIOPREV study. Researchers developed a microbiota-based risk score that may improve secondary prevention.

Pregnancy complications may predict future heart disease risk

Complications during pregnancy (or adverse pregnancy outcomes), like gestational diabetes and newly developed high blood pressure, act as nature's stress test and may uncover an individual's risk for heart disease later in life, according to new research published in the JACC, the flagship journal of the American College of Cardiology.

Eating ultra-processed foods may rewire your brain’s hunger and reward circuits

High intake of ultra-processed foods is linked to adverse metabolic health and microstructural brain changes in regions that control appetite and reward. These effects occur both through obesity-related pathways and independently via inflammation and dyslipidemia.

WINREVAIR™ (sotatercept-csrk) reduced the risk of a composite of all-cause death, lung transplantation and hospitalization for pulmonary arterial hypertension (PAH) by 76% compared to placebo in the phase 3 ZENITH trial

Merck, known as MSD outside of the United States and Canada, today announced the first presentation of results from the Phase 3 ZENITH trial evaluating WINREVAIR™ (sotatercept-csrk) compared to placebo in adults with pulmonary arterial hypertension (PAH, Group 1 PH) WHO* functional class (FC) III or IV at high risk of mortality who were on maximum tolerated background PAH therapy. At a median follow-up of 10.6 months (range, 0.3-26.1), WINREVAIR reduced the relative risk of major morbidity and mortality events (the composite of all-cause death, lung transplantation and PAH worsening-related hospitalization of ≥24 hours) by 76% (HR=0.24 [95% CI, 0.13-0.43]; p<0.0001 [1-sided]) compared to placebo.

Researchers receive $2.7 million NIH grant to develop the next generation of synthetic blood

Blood loss is the leading cause of death in trauma patients between the ages of 1 and 46 years, largely because they cannot access safe blood sources quickly enough. A possible solution? Freeze-dried synthetic blood.
