A new cost-effectiveness analysis shows that endovascular repair of abdominal aortic aneurysms costs £1,500 more per patient than open surgery but produces better health outcomes, meeting UK cost-effectiveness thresholds. The findings could reshape NHS procurement decisions and surgical training priorities as hospitals weigh upfront device costs against long-term patient benefits and reduced complications.EN

A new study reveals that how AI recruitment systems look—their avatar's skin tone, gender presentation, or other visual features—significantly influences whether hiring managers trust and follow their recommendations. The finding suggests companies deploying AI hiring tools may inadvertently amplify human bias rather than reduce it, raising questions about fairness in talent acquisition.EN

Researchers found that multiple myeloma and its standard treatments durably reshape bone marrow immunity, leaving patients vulnerable to infections long after recovery. The discovery that adjuvanted vaccines—like mRNA COVID shots—restored immune responses in all patients suggests a practical intervention for preventing infections, the leading cause of death in myeloma survivors.EN

Researchers in Uganda's island districts identified the human and systemic barriers preventing death registration—from poverty and cultural stigma to missing government workers and supplies. The findings could reshape how governments and health organizations design interventions to strengthen vital statistics systems that inform public health decisions and resource allocation.EN

Researchers have identified digital markers that can reliably signal depressive episodes in bipolar disorder patients using smartphone activity, sleep trackers, and mood reports—a step toward automating mental health monitoring. The finding could reshape how payers and digital health companies approach depression screening and intervention, moving from reactive crisis response to continuous, early detection.EN

A new study identifies heart rate variability as a measurable indicator linked to long-term survival outcomes in women with ischemic heart disease.

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

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

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

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

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

A major European Heart Journal analysis argues that doctors should aggressively treat newly detected atrial fibrillation—not just manage symptoms. The shift matters because early intervention on lifestyle and heart disease risk factors could prevent progression and reduce healthcare costs down the line.EN

**PET-tracer avslöjar lungödem före symptom — öppnar vägen för målinriktad TNF-terapi** Lungödem drivs ofta av inflammatoriska cytokinen TNF, men läkare saknar verktyg för att mäta TNF-aktivitet utan invasiv provtagning. Uppsala universitet presenterar [Ga-68]Z(0185), en ny PET-tracer baserad på Affibody-molekyler, som detekterar TNF-driven inflammation direkt i lungvävnad. Forskare märkte radionuklidet gallium-68 på molekylen med radiokemisk renhet över 95 procent. I råttmodell med bleomycin-inducerad lungskada visade PET-avbildningen dubbel så högt tracer-upptag i inflammerad lung jämfört med frisk vävnad (SUVmean 0,58 mot 0,25, statistiskt signifikant). Makrofaginfiltration bekräftades histologiskt. För regionvården betyder detta potentialen att stratifiera idiopatisk lungfibros-patienter före behandling och övervaka TNF-inhibitors effekt objektivt. Gatekeepern är nu regulatorisk vägledning för klinisk validering — Uppsala universitet leder utvecklingen mot först diagnostisk användning för personaliserad lungbehandling.

Stabil PSA under behandling med 5-alfa-reduktashämmare efter negativ prostatbiopsi identifierar män med mycket låg risk för prostatacancerdöd. En nationell populationsstudie från Sverige följde 1 248 män i tio år: 901 hade stabil PSA och 347 stigande PSA under de första två behandlingsåren. Bland män med stabil PSA utvecklades prostatacancer hos 8,3 procent, medan motsvarande siffra för stigande PSA var 18 procent. Prostatacancerdödligheten var markant lägre i gruppen med stabil PSA (standardiserad mortalitetskvot 0,19) jämfört med stigande PSA (1,20). De flesta cancerfallen i stabila-PSA-gruppen var låggradiga tumörer. Resultaten från Uppsala universitet och Jönköping kan förändra övervakningsstrategier för denna patientgrupp, särskilt inom regionvården där resurser för upprepade screeningundersökningar är begränsade.

**Maskinlärningsmodell kan inte identifiera hjärtpatienter i arrest-risk** Ett nyutvecklat prediktionsverktyg för att identifiera hjärtsviktspatienter med högt risk för hjärtstillestånd presterar dåligt på individnivå. Forskare vid Göteborgs universitet och Sahlgrenska sjukhuset byggde en Random Survival Forest-modell med 82 prediktorer från Svenska hjärtsviktregistret, baserad på 45 068 nydiagnostiserade patienter (2005–2021). Endast 5 procent erhöll återupplivning, medan 71 procent dog utan intervention. Modellens C-index nådde endast 0,52 och AUC-ROC 0,63–0,65 — långt under klinisk användbarhet. Forskarna konkluderar att dödsrisken utan återupplivningsförsök överskuggar förmågan att skilja ut arrest-kandidater. För regionala inköpare och kliniker innebär detta att algorithmer baserade på befintliga registerdata inte löser behovet av bättre riskövervakning. Nya datakällor eller biologiska markörer krävs före någon implementering kan motiveras.

Tidig mobilisering under Achilles-senläkning bevarar mikrostrukturen bättre än immobilisering, enligt en svensk studie från Lund och Linköpings universitet. Forskarna analyserade läkningsprocessen på nanoskala vid en, två och tre veckor efter skada genom synkrotronbaserad röntgenspridning kombinerad med mekanisk belastningsprovning. Resultaten visar att immobiliserade senor utvecklade sämre förmåga till fibrilltillskott och elastisk deformation redan efter en vecka. På vävnadsnivå sågs inga tydliga skillnader, men nanoskalan uppvisade markanta avvikelser — högre spatial variation och minskad kollagenfibrilrekrytering vid avlastning. Fyndet adresserar en klinisk lucka: dagens rehabiliteringsprotokoll för Achilles-senruptur saknar vetenskaplig grund för optimal belastningshantering. För regionvården och MedTech-aktörer öppnar detta vägen för nya rehabiliteringsriktlinjer och diagnostiska verktyg för att förhindra omruptur, en vanlig komplikation som drabbar cirka 30 procent av patienterna.
