Cleveland Clinic study links gut microbe byproduct to heart arrhythmia

A Cleveland Clinic-led study shows a connection between elevated blood levels of TMAO (trimethylamine N-oxide) - a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products - and a higher risk of atrial fibrillation.

New bacterial control strategy helps revive failing last-line antibiotics

Antimicrobial resistance is one of the world's most alarming public health challenges, because the multidrug-resistant (MDR) gram-negative bacteria increasingly render even last-line antibiotics ineffective, leading to substantially higher mortality rates.

GLP-1 receptor agonists may increase hair loss risk

Use of glucagon-like peptide-1 (GLP-1) receptor agonists used to treat type 2 diabetes and obesity are associated with an increased risk of hair loss (alopecia) in adults with type 2 diabetes, finds a study published by The BMJ today.

Generic semaglutide could improve diabetes treatment affordability in Canada

In a novel analysis examining the economic implications of generic semaglutide entering the Canadian market, researchers predict that the anticipated price reductions of up to 70% will dramatically increase both the cost-effectiveness and health system affordability of therapy options for patients with type 2 diabetes and high cardiorenal risk.

Study reveals sex-based protein differences across lung cancer types

Biological sex factors into cancer in ways you might not expect. In lung cancer, a form called squamous cell carcinoma disproportionately affects males while adenocarcinoma occurs more frequently in females.

Common heart risk calculators effectively predict certain types of cancer

Risk calculators that doctors use to estimate a person's risk of a heart attack or stroke work about as well for predicting certain cancers, according to a new study by UCL (University College London) researchers.

Experts urge focus on prevention to tackle global heart failure

Heart failure already affects more than 60 million people worldwide and is one of the leading causes of hospitalization among people over the age of 65.

Thymus hormone identified as key player in reversing age-related inflammation

Chronic, low-grade inflammation in the body-a phenomenon known as "inflammaging" because it increases with age-has been linked to many of today's leading causes of illness and death, including cancer, heart disease, metabolic conditions and neurodegenerative diseases.

Study examines the link between blood type and cardiovascular risk in hemodialysis patients

Do you know your blood type? It is important information that is used for blood transfusions, but few realize blood types could also be linked to disease risks. In the general population, people with blood type O have been reported to have a lower risk of cardiovascular disease and cardiovascular mortality.

Study tests chronotype’s liver link and finds no significant association

Researchers found no significant association between chronotype and FibroScan-derived liver fat or stiffness in 119 medication-naïve adults with overweight or obesity. The exploratory findings cannot exclude smaller effects, particularly for fibrosis, and require confirmation in larger longitudinal studies.

High costs continue limiting insurance coverage for GLP-1 medications

Despite growing evidence that GLP-1 medications improve health and are worth their cost, many insurance plans still limit coverage. University of Mississippi researchers are examining why, and where that leaves patients.

Gut microbial metabolites may shape vulnerability to stress-related mental disorders

Gut microbiome-derived metabolites may influence stress-related mental disorders through neural, immune, endocrine, and epigenetic pathways. Evidence is strongest for depression and preclinical models, while larger longitudinal human studies are needed to establish causality and clinical value.

Rising antimicrobial resistance in children threatens life-saving antibiotic effectiveness

Antimicrobial resistance in children is rising globally and will worsen over the next decade, threatening the effectiveness of life‑saving antibiotics, according to a world-first monitoring platform.

Popular diabetes drugs do not alter the risk of developing a blinding eye condition

An estimated 27% of U.S. adults with diabetes are using glucagon-like peptide-1 receptor agonists (GLP-1 RAs) - a type of medication that mimics the GLP-1 hormone - to lower blood sugar and support weight loss. Some research has suggested that their use can reduce the risk of developing other diseases.

NOX4 inhibition may protect hearts affected by Duchenne muscular dystrophy

Researchers at the University of South Florida USF Health Morsani College of Medicine have identified a potential pathway that could protect cardiac function in people with Duchenne muscular dystrophy, a progressive and fatal genetic disease that weakens the body's muscles.

Diet helps people lose weight regardless of genetic obesity risk

A study reveals dietary coaching aids weight loss equally in individuals with high and low genetic obesity risk, challenging genetic determinism in weight loss.

Researchers identify immune cell receptor that drives organ aging process

We may age at different rates, but none of us escapes aging. A study in mice and in human cells by Stanford Medicine researchers pins much of the blame on a particular type of immune cell's increased inability, with advancing age, to gobble up another immune cell type.
