A study of nearly 10,000 pregnant women across Bangladesh, Pakistan, and Tanzania found that elevated HbA1c levels in early pregnancy significantly increase the risk of adverse outcomes. The findings highlight a critical gap in maternal healthcare in low-income countries, where routine glucose monitoring during pregnancy remains limited despite clear clinical need.EN

Acute mesenteric ischaemia, a life-threatening blockage of blood vessels supplying the intestines, affects fewer than 1 in 2,500 hospital admissions but kills patients at alarming rates when diagnosis is delayed. A global study reveals patients wait 24 hours before reaching hospital, then another 6 hours for diagnosis—delays that likely determine survival odds and should reshape emergency protocols.EN

A 20-year study of arthritis patients reveals that higher body weight correlates with worse quality of life and more severe disease symptoms. The findings suggest weight management could become an important treatment lever for rheumatologists—and a cost control opportunity for health systems managing chronic inflammatory conditions in younger populations.EN

Researchers analyzing dietary patterns in 680 cancer patients identified a breakfast-focused diet as protective against colorectal cancer, with effects strongest in women. The finding could reshape food industry marketing and public health messaging around breakfast consumption and cancer prevention.EN

A new study reveals that estrogen significantly affects women's ability to recognize emotions in others, but the effect works in counterintuitive ways depending on whether hormones are compared within or between individuals. The finding could reshape how employers, healthcare providers, and psychologists understand cognitive performance variations across the menstrual cycle.EN

Researchers have solved a long-standing chemistry problem that blocks the ability to monitor how experimental cancer medicines move through patients during clinical trials. The breakthrough could accelerate testing of promising treatments and help doctors personalize drug dosing for better outcomes.EN

Researchers have developed a method to filter out breathing machine noise from pulmonary artery pressure readings, making real-time heart function measurements more reliable in intensive care units. The advance could help clinicians make faster treatment decisions for critically ill patients and reduce unnecessary interventions based on faulty data.EN

Researchers have automated a way to map tumor blood flow throughout the entire body using advanced PET imaging, potentially giving oncologists a faster way to track how well cancer treatments are working. The technique could streamline how doctors monitor metastatic prostate cancer and other cancers without the manual analysis that currently slows clinical adoption.EN

Major European medical associations have issued a joint statement defining and distinguishing between substandard and disrespectful treatment during childbirth, moving away from the term 'obstetric violence.' The statement aims to drive systemic change in maternity care standards across hospitals and birth centres, with implications for healthcare quality, liability, and patient satisfaction metrics.EN

Researchers found that higher circulating caffeine levels are linked to lower risks of obesity and osteoarthritis, based on genetic analysis of how people metabolize the drug.
