Researchers systematically reviewed and modeled Toxoplasma gondii seroprevalence across 25 European countries. The study found striking regional differences, with highest infection levels in eastern and western Europe and lowest in the UK and northern regions.

This review examined 27 preclinical studies on honey and Alzheimer’s disease, showing honey’s bioactive compounds counter oxidative stress, inflammation, and amyloid buildup. Despite promising lab results, no human trials exist, underscoring the need for clinical research.

Metformin boosts human oligodendrocyte differentiation and myelination across stem-cell, organoid, and chimera models. The study links these effects to mitochondrial metabolic shifts, supporting its potential as a therapy for multiple sclerosis.

Breastfeeding at six months was linked to higher IQ, better reading and math skills, and improved conversational abilities in children, according to the ALSPAC study. The findings, based on 42 significant outcomes, highlight long-term cognitive advantages but stop short of proving causality.

A cross-sectional study of 149 postmenopausal women found that greater adherence to a modified Mediterranean diet was linked to lower odds of moderate to severe hot flashes and sexual symptoms. While psychological and physical domains showed no significant association, the results support further evaluation of diet as a non-hormonal strategy for menopausal care.

Cancer cells can break down the protective covers around nerves, causing nerve injury that triggers chronic inflammation leading to immune exhaustion and eventual resistance to immunotherapy, according to new research from The University of Texas MD Anderson Cancer Center.

A new study maps out the timeline of DNA damage for multiple myeloma, the second most common blood cancer.

Nearly a quarter of people over the age of 40 experience painful osteoarthritis, making it a leading cause of disability in adults.

​Prostate cancer is among the most common cancers in men and a leading cause of cancer-related deaths. With improved detection and therapies, survival rates have risen, but this progress comes with a new concern: the risk of secondary primary malignancies.

Heart failure with preserved ejection fraction (HFpEF) appears to develop as a result of changes in the biology of a person's internal fat tissue, according to the Adipokine Hypothesis, a new way of understanding how fat may impact the heart.

Drug-coated stents and balloons were not associated with reduced risk of amputation or improved quality of life compared with uncoated devices in two trials in peripheral artery disease (PAD), according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

An individually tailored multidimensional risk-based treatment strategy was not associated with improvements in clinical outcomes compared with usual guideline-based care in patients with atrial fibrillation (AF), according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

Routine coronary computed tomography (CCT)-based follow-up after percutaneous coronary intervention (PCI) of the left main coronary artery did not reduce death, myocardial infarction (MI), unstable angina or stent thrombosis compared with symptom-based follow-up, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

Prophylactic implantable cardioverter defibrillator therapy did not reduce mortality in patients with a prior myocardial infarction, persistent moderate left ventricular systolic dysfunction and abnormal ECG markers, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

A mail-based atrial fibrillation (AF) screening programme with ECG-patch monitoring led to a modest long-term increase in AF diagnosis and anticoagulation exposure in older patients at moderate-to-high stroke risk, according to a late-breaking trial presented in a Hot Line session today at ESC Congress 2025 and simultaneously published in JAMA (The Journal of the American Medical Association).

The widely used diabetes drug metformin changes blood metal levels in humans. The Kobe University study is an important step in understanding the drug's many actions and designing better ones in the future.

In a discovery that could expand the array of current cancer immunotherapy treatments, scientists at Harvard Medical School have identified a new molecular brake that hinders the ability of T cells to attack tumors.

Investigating aging anxiety in China, this research links socioeconomic status to mental health, showing how education and income can alleviate fears of aging.

The presence of viridans streptococci in coronary plaques indicates a role in atherosclerosis, potentially influencing heart disease outcomes.

Daily blueberry powder given to infants during complementary feeding modestly influenced allergic symptom resolution and shaped immune biomarker–microbiota associations. Findings suggest early diet may play a role in immune development, though results are preliminary and exploratory.
