Percutaneously reducing secondary mitral regurgitation in heart failure appears futile

Researchers found that reducing secondary mitral regurgitation in heart failure patients did not improve survival or symptoms, suggesting the procedure is futile. Despite successful procedure completion, there was no significant difference in primary endpoint outcomes between intervention and medical treatment groups.

Paternal diet and offspring health

A new study suggests that paternal diet influences offspring health by affecting sperm DNA methylation tags and seminal plasma immunological responses. Mice fed a low-protein diet had overweight offspring with dysfunctional metabolism, highlighting the importance of a healthy father's nutrition for child well-being.

Diseased heart muscle cells have abnormally shortened telomeres, Stanford researchers find

Researchers at Stanford University School of Medicine discovered that people with cardiomyopathy have abnormally short telomeres in their heart muscle cells. This finding opens the door to new research and drug discovery, potentially allowing for the identification of individuals at risk for heart failure due to genetic defects.

Antithrombin drug not effective in heart failure with sinus rhythm and coronary disease

The COMMANDER HF trial found that rivaroxaban did not significantly reduce the risk of death, myocardial infarction, or stroke in patients with recent worsening of chronic heart failure and coronary artery disease. Rivaroxaban was associated with a lower rate of nonfatal stroke, but a higher risk of major bleeding compared to placebo.

Physicians deserve answers as public service loan forgiveness program hangs in the balance

Health policy experts argue that expunging the program could worsen educational debt in America and threaten the medical workforce. The authors call for clarity and swift decisions to resolve the uncertainty, which is particularly unfair to recent graduates who are already facing significant loan debt.

Algae a threat to walleye vision, study finds

A new study led by Ohio State University found that algae poses a greater threat to freshwater fish vision than sediment, causing a 40% decrease in their ability to see in cloudy water. This could jeopardize the future of walleye and other fish populations if harmful algal blooms persist.

Can 'microswimmers' swim through jelly?

Scientists from Tokyo Metropolitan University studied how microswimmers navigate gels with contrasting results based on swimmer features and size relative to the gel's mesh. They discovered two mechanisms for achieving motion, one through breaking time-reversal symmetry and the other by modulating arm amplitudes

Drug reduces deaths and hospitalizations from underdiagnosed form of heart failure

A phase three clinical trial has shown that tafamidis can reduce deaths by 30% and cardiovascular-related hospitalizations by 32%. The treatment also slows the decline in quality of life among patients with transthyretin amyloid cardiomyopathy. If approved, it would be the first medical therapy for this life-threatening disease.

Beluga whales and narwhals go through menopause

Researchers discovered that beluga whales and narwhals undergo menopause, mirroring killer whales' behavior. This reproductive strategy may have evolved due to increased relatedness among family members and the need for older females to contribute to group survival through knowledge sharing.

Study defines mechanisms behind focused-ultrasound-assisted treatment of brain tumors

A study defines mechanisms behind focused-ultrasound-assisted treatment of brain tumors, improving drug delivery across the blood-brain barrier and into abnormal tumor tissues. The approach enhances permeability of endothelial cells lining tumor blood vessels, increasing cellular uptake of anti-cancer drugs.
