A correction to a major breast cancer trial reveals new concerns about how well patients stick with treatment when palbociclib is added to hormone therapy. The finding matters to drug makers, insurers, and hospitals because poor adherence undermines clinical benefits and drives up real-world treatment costs.EN

Researchers in Scandinavia have identified a significant weakness in colposcopy — the procedure that confirms abnormal screening results — within otherwise successful cervical cancer screening programs. The finding matters for health systems worldwide that rely on similar multi-step screening chains to prevent cancer.EN

Half of girls referred for ADHD assessment show signs of undiagnosed trauma, a new study finds, suggesting clinicians may be treating the wrong condition. The finding raises concerns about diagnostic accuracy and treatment effectiveness, with implications for clinical protocols and resource allocation in child psychiatry services across Europe.EN

A review of 64 educational studies finds that schools systematically dismiss knowledge and perspectives from students based on race, disability, gender, and economic status. The discovery matters to administrators and policymakers because it reveals a concrete mechanism—called discriminatory epistemic injustice—that undermines inclusion efforts, even when policies explicitly aim for equity.EN

A new review reveals a widening gap between clinical evidence and how physicians use blood pressure medications to treat septic shock. The findings suggest hospitals may be missing opportunities to improve survival rates and reduce costs by aligning practice with emerging research on optimal vasopressor selection and dosing.EN

Researchers developed KneeXNet-2.5D, an artificial intelligence system that automatically identifies cartilage and meniscus damage in knee MRI scans—work that currently requires hours of manual analysis by radiologists. The lightweight software runs on basic hospital computers, making it deployable in rural clinics and low-income settings where specialist expertise is scarce.EN

Artros klassificeras traditionellt som degenerativ sjukdom, men inflammatoriska processer spelar en avgörande roll i sjukdomsprogressionen hos många patienter. Forskare från Karolinska Institutet, Universidad de Valencia och Instituto de Investigación Marqués de Valdecilla presenterar att låggradsinflammation driver smärta, synovialförändringar och strukturell ombyggnad i artros. Denna omvärdering av sjukdomsmekanismen påverkar direkt hur kliniker fenotypiserar patienter och prognostiserar sjukdomsförlopp. Reviewen analyserar molekylär, cellulär, bilddiagnostisk och klinisk evidens för inflammationens roll och diskuterar konsekvenser för framtida behandlingsutveckling. För inköpsansvariga inom regionvård och MedTech-investerare innebär detta att antiinflammatoriska interventioner och inflammationsmarkörer får större betydelse vid behandlingsval och biomarkörutveckling. En inflammationsfokuserad fenotypisering kan möjliggöra mer målstödd terapi och bättre patientstratifiering redan nu.

Forskare från bangladeshiska universitet och Karolinska Institutet presenterar EDNet-20, en djupinlärningsmodell för automatisk diagnostik av ögonsjukdomar baserad på ögonbottenfotografier. Systemet hanterar multipel etikett-klassificering — det vill säga identifiering av flera samtidiga sjukdomstillstånd i samma bild — vilket motsvarar klinisk verklighet där patienter ofta har överlappande ögonpathologier. Modellen optimerar befintlig arkitektur genom nätverksförenkling och träningsteknik för att uppnå snabbare inferenstid utan väsentlig förlust i diagnostisk noggrannhet. Denna effektivering öppnar för driftsmiljöer med begränsad beräkningskapacitet. Resultaten är relevanta för regionvård som utvärderar AI-stödd screening av diabetisk retinopati och andra ögonsjukdomar. Eftersom detta är förpublicering är implementering i klinisk miljö ännu avlägsen, men modellen illustrerar vägen mot decentraliserad diagnostik i primärvården och låginkomstländer.
