The finding suggests that dental assessment and treatment may be a overlooked but modifiable factor in surgical planning, potentially improving long-term results for cancer centers and patient outcomes.EN

Researchers discovered that endometrial polyps develop when cells fail to mature properly and blood vessels don't remodel correctly, according to a new single-cell analysis. The finding could eventually enable targeted treatments for the growths, which affect fertility and require surgical removal in thousands of women annually.EN

A study of 159 hospitalized seniors found that nearly one in ten who fell suffered fractures—yet many were never treated for osteoporosis. The finding suggests hospitals and care systems are leaving a straightforward intervention unused, raising questions about clinical protocols and liability exposure in geriatric wards.EN

A new antiepileptic medication reduced seizure risk in stroke patients prone to post-stroke epilepsy, according to a phase 2 trial published in The Lancet Neurology. If confirmed in larger studies, the finding could change how hospitals treat high-risk stroke survivors and reduce disability and healthcare costs from preventable seizures.EN

Researchers confirmed that a quantitative MRI technique can accurately map brain tissue during pediatric tumor operations, potentially improving surgical precision and outcomes. The finding validates a technology that could become standard in operating rooms, with implications for surgical planning, training protocols, and equipment manufacturers developing intraoperative imaging systems.EN

Researchers have identified metabolic partnerships between bacteria that colonize urinary catheters, potentially explaining why these infections are so difficult to treat. The findings could lead to new strategies for breaking up bacterial communities and reducing hospital-acquired infections—a major cost driver for healthcare systems.EN

Exponering för modersmökning under graviditet ökar ADHD-risken hos barn med 67 procent enligt en europeisk multicenteranalys av 156 563 barn. Karolinska Institutet ledde studien, som kombinerade data från sju europeiska kohorter och använde Random Forest-maskininlärning för att identifiera vilka prenatala miljöfaktorer som bäst förklarade ADHD-diagnos. Forskarna testade miljöfaktorer som luftföroreningar, stadsmiljö och socioekonomiska förhållanden. Modersmökning framstod som den mest robust associerade faktorn. Övriga variabler visade svagare samband och försvagades ytterligare när modeller justerades för confounders. För regionvården innebär resultaten ett konkret fokusområde för graviditetshälsa och rökavvänjningsinsatser. Inköpschefer inom MedTech bör notera efterfrågan på screening- och diagnostikverktyg för ADHD. För regulatorer bekräftas miljöfaktorer som relevanta för kliniska riktlinjer om prenatal exponering.

**Design Games som utvecklingsmetod för vårdsystem** Samarbetet mellan sjukvårdsproviders, teknikföretag och beslutsfattare kräver nya sätt att testa gemensamma lösningar innan fullskalig implementering. KTH Royal Institute of Technology demonstrerar hur designspel fungerar som repetitionsarena för att utforska framtida vårdmodeller och identifiera samarbetsfriktioner tidigt. Metoden låter multidisciplinära team simulera scenarion från systemdesign till klinisk användning, vilket avslöjar kommunikationsgap och operativa motsättningar utan risker. Genom rollspel och scenariobaserad träning fångar parterna upp inkompatibilitet i processer och förväntningar innan investeringar genomförs. För inköpschefer och regulatoriska specialister innebär detta en möjlighet att reducera implementeringsrisker på nya MedTech-lösningar. Metoden accelererar också innovation genom att förkortad tiden från prototyp till färdig vårdsystem. Ansatsen är särskilt relevant för regionala satsningar på digitalisering och processutveckling.

Three veterinary teaching hospitals have demonstrated that a standardized biorepository—a centralized facility for storing biological samples—is both feasible and operationally productive. The finding matters because it provides a blueprint for how medical institutions can pool resources to enable faster disease research and drug discovery without duplicating expensive infrastructure.EN

A new study reveals that our brains rely on two competing systems to recognize our own bodies: gut-level sensory signals and higher-order thinking. When one system dominates over the other, it may explain why people with psychosis lose touch with reality. The findings could reshape how clinicians assess and treat disorders of self-perception.EN

A new study reveals that prenatal supplements of omega-3 fatty acids and specific probiotics alter the immune properties of breast milk itself—potentially explaining why they reduce childhood allergies. The findings could reshape how doctors advise pregnant women and influence the infant nutrition market, currently worth billions globally.EN

KarXT, a novel antipsychotic combining xanomeline and trospium chloride, outperforms cheaper generic treatments while costing less than branded alternatives, according to a new cost-effectiveness analysis. The finding could reshape treatment protocols and insurance coverage decisions for a condition affecting 1.1% of U.S. adults.EN

Researchers have identified structural differences in a key blood test used to diagnose bone disorders, revealing why the same marker produces vastly different results across patients. The discovery could lead to more accurate tests for kidney disease complications and rare genetic bone conditions—opening new markets for diagnostic companies and improving treatment decisions for millions of patients.EN

A new commentary highlights how COVID-19 derailed management of hypertensive disorders during pregnancy, raising concerns about maternal and fetal outcomes. For health systems and insurers, the findings underscore vulnerabilities in obstetric care continuity during public health crises—a critical risk for maternal mortality and litigation.EN

Europe's major research institutions have agreed on minimum standards for researcher pay, job security, and career advancement across the continent. The move aims to prevent brain drain and boost research productivity by making academic careers more competitive with industry roles.EN

Researchers identified specific patient factors that predict failure of arthroscopic Bankart repair, a common shoulder stabilization surgery that fails in up to 30% of cases. The findings could help surgeons and insurers better assess which patients need closer monitoring or alternative treatments, potentially reducing costly repeat surgeries.EN

Scientists are testing a new oral contraceptive combining a GnRH antagonist with a synthetic estrogen, designed to prevent ovulation without progestins—the hormone linked to increased breast cancer risk. If successful, the approach could reshape contraceptive strategy for women across decades while potentially reducing one of medicine's most prevalent cancers.EN

Surgeons successfully used a less invasive technique called chimney repair on one in six emergency aortic rupture patients, preserving kidney blood flow while sealing life-threatening tears. The findings suggest this 14-year dataset could reshape hospital protocols and expand which patients can avoid traditional open surgery.EN

Researchers systematically measured how cannabis-like compounds activate distinct signaling routes in cells, finding some trigger multiple pathways simultaneously while others target specific routes. The discovery could unlock safer cannabis-derived treatments with fewer side effects, a major bottleneck for pharmaceutical development in this emerging drug class.EN

A nationwide study of 83,000 patients shows that weight-loss surgery can be performed safely even in people with the highest obesity levels, with complication rates no higher than in less obese groups.
