A major trial shows that edoxaban anticoagulation therapy reduces strokes and blood clots in heart patients experiencing prolonged irregular heartbeats lasting 24 hours or longer. The finding could reshape treatment protocols for millions with atrial arrhythmias and expand the market for anticoagulant therapies.EN

A seven-country study found COVID-19 slashed sexual and reproductive health visits by 20-56% in most nations, but Canada bucked the trend with a 16% increase. The findings highlight how virtual care infrastructure can preserve essential health services during crises—a lesson for policymakers designing health system resilience.EN

A 20-year European study reveals that abnormal lung function develops in two distinct waves—some people show signs before age 40, others between 40 and 60. The findings could shift how healthcare systems screen for respiratory disease and design prevention programs, potentially saving costs by catching problems earlier.EN

Takotsubo syndrome, a reversible heart condition triggered by emotional stress, is being missed and mismanaged in clinical practice due to diagnostic confusion. An international expert panel has identified specific challenges and released recommendations to improve detection and treatment—potentially reducing patient harm and unnecessary interventions in hospitals worldwide.EN

A new analysis reveals that most occupational health interventions miss the mark because they ignore organizational complexity and fail to track what actually happens during implementation. By applying lessons from two major European projects, researchers show that success requires multi-level theory, stakeholder involvement, and abandoning simple before-and-after assessments.EN

Researchers identified a consistent connection between inflammatory markers and perinatal depression, affecting 10-20% of pregnant women globally. The finding could reshape how healthcare systems screen for and treat the condition, potentially improving outcomes for millions of women and reducing long-term health costs.EN

A major European trial found that giving children with high-risk rhabdomyosarcoma additional oral chemotherapy after standard treatment provides no survival benefit. The finding challenges current practice and could spare hundreds of young patients from unnecessary drug exposure and side effects annually.EN

A panel of cardiologists has published consensus guidance on how to design and measure outcomes in studies testing catheter ablation for atrial fibrillation. The move aims to make research more consistent and comparable, potentially accelerating how quickly device makers and hospitals can evaluate whether new technologies actually work better than existing options.EN

Researchers have developed the first validated equation for using a handheld bioimpedance device to accurately measure muscle and fat in young children—a breakthrough that could streamline pediatric health screening and nutrition assessment. The finding opens a path to faster, cheaper body composition testing in clinical settings and schools where traditional imaging is impractical.EN

Researchers surveyed 65 Swedish teenagers and identified the specific daily stressors affecting them—from academic pressure to social demands—creating a roadmap for schools to support mental health before problems escalate. The findings could help educators and policymakers design targeted interventions that address adolescents' real-world challenges rather than generic wellness programs.EN

A new study in Arctic Russia reveals a critical gap in maternal mental health care: midwives report insufficient time for psychological screening despite postpartum depression affecting one in six women globally. The finding suggests healthcare systems need to redesign workflows and training to catch cases early, when intervention is most effective and costly complications can be prevented.EN

A major clinical trial found that women with chronic heart disease are less likely to receive revascularization procedures than men, even when referred for invasive treatment. The finding raises questions about equity in cardiology care and could influence clinical guidelines and hospital protocols for cardiac intervention decisions.EN

A new study of nearly 640 preschoolers found that parents' estimates of their children's sleep duration align closely with objective wearable data on weekdays, validating a cheaper data-collection method. The finding could reshape how pediatric health researchers and clinics measure sleep without expensive equipment—critical as sleep duration emerges as a measurable risk factor for childhood obesity.EN

A consensus statement from European perinatologists has redefined how doctors should describe oxygen deprivation in babies during labor, replacing vague terms like "fetal distress" with precise clinical language. The shift aims to reduce medical disputes, improve doctor-parent communication, and standardize care across hospitals—a move that could reshape malpractice liability and training protocols.EN

A major clinical trial shows potassium-enriched salt reduces stroke risk and deaths. New analysis reveals potassium increases matter as much as sodium reduction—a finding that could reshape how food companies and public health officials approach salt replacement strategies and cardiovascular prevention.EN

Swedish researchers analyzing 132,000 workers found that employees in heavily female-dominated workplaces took significantly more sick leave than those in gender-balanced settings. The finding suggests workplace gender composition may influence health outcomes—a concern for HR leaders managing workforce costs and retention.EN

A large Danish study challenges a common assumption in child protection: that parents dealing with severe physical illness are significantly more likely to abuse their children. The finding could reshape how authorities allocate limited resources for abuse prevention and child welfare screening.EN

A new study shows that gastric bypass surgery and dramatic weight loss alter how a key intestinal protein handles digoxin, a widely-used heart medication. The finding could affect drug dosing for millions of obese patients undergoing surgery and raises questions about whether other medications need adjustment after bariatric procedures.EN

Researchers discovered that cells can detect and destroy endosomes—cellular compartments—when malfunctioning proteins cause uncontrolled signaling linked to cancer progression. The finding identifies a previously unknown cellular surveillance mechanism called simaphagy, which could guide development of new cancer therapies targeting this quality-control pathway.EN

Researchers have structurally characterized seven common mutations in a G protein that controls critical cellular signals, using a novel technique that overcomes previous scientific barriers. The work could accelerate drug development for diseases caused by these mutations, including certain cancers and endocrine disorders where these proteins malfunction.EN

A new analysis shows that Delta and Omicron waves significantly disrupted routine malaria services at three Ugandan health facilities, with fewer patients tested and treated despite ongoing transmission. The findings underscore a critical gap in pandemic preparedness: maintaining essential disease programs during health crises.EN

A new study of displaced Somali families reveals a stark nutritional divide—95% of households report adequate diet diversity, yet only a third of young children eat enough food variety. The gap suggests aid programs may be missing how resources actually flow within families, with implications for humanitarian response strategies across conflict zones.EN

Researchers have validated a short questionnaire that helps parents and educators identify emotional and behavioral difficulties in preschoolers as young as one year old. The finding matters to early childhood programs and healthcare systems seeking cost-effective ways to catch developmental concerns early, when intervention is most effective and less expensive.EN

When Norway locked down in early 2020, psychiatric hospitalizations and specialist appointments plummeted—yet antidepressant prescriptions barely fell. The disconnect reveals how pandemic restrictions disrupted face-to-face care while pushing reliance on medication, a pattern policymakers must account for in future health crises.EN

A study of 165 patients at two major European cancer centers shows that carcinoid heart disease—a serious side effect of advanced intestinal neuroendocrine tumors—strikes 25% of those with carcinoid syndrome. The finding could help doctors identify which patients need earlier cardiac monitoring, potentially improving outcomes for a population with limited treatment options.EN
