Kvinnor med lobar hjärnblödning uppvisar andra bilddiagnostiska mönster än män, enligt en större svensk studie från Skåne-regionen. Forskarna jämförde radiologiska fynd hos 1 398 patienter (785 män, 613 kvinnor) med spontan supratentoriell intracerebral blödning mellan 2016–2021, registrerade i Riksstroke. Medan blödningsvolym, lokalisering och använd antitrombotisk behandling var likartade mellan könen, var kvinnorna i genomsnitt 6 år äldre (79 mot 73 år). Vid lobar blödning var kvinnligt kön oberoende associerat med subarachnoid extension och CT-fynd förenliga med högre sannolikhet för cerebral amyloid angiopati (CAA). Resultaten föreslår liknande blödningsseveritet mellan könen men skillnader i lobar blödnings morfologi. För regionala strokeenheter och inköpschefer understryka dessa fynd värdet av könsspecifik tolkning vid bilddiagnostisk klassificering av ICH, särskilt för riskvärdering och långtidsuppföljning av äldre patienter.

Sjuksköterskor i Ujjain, Indien använder digitala verktyg för klinisk information, men saknar strukturerade evidensbaserade appar — en marknadskluft för mHealth-utvecklare. En tvärsnittsundersökning bland 453 sjuksköterskor från tre sjukhus visade att 99 procent använder smartphone och internet, främst för att söka symptom (97 procent) och behandlingsmetoder (91 procent). Google och YouTube är huvudsakliga informationskällor, och 88 procent deltar i informella sociala mediegruppör för klinisk rådgivning. Trots detta har endast sex procent installerat mobilhälsoappar — huvudsakligen på grund av låg medvetenhet, inte motvilja. 98 procent är villiga att använda en trovärdig, evidensbaserad applikation. Karolinska Institutet och medicinska högskolan i Ujjain identifierar här ett utvecklingsbehov för tillförlitliga digitala verktyg som kan ersätta oprövade onlinekällor och stödja kliniska beslut inom moder- och nyföddhälsa i låginkomstländer.

A Swedish study shows that a structured intervention helping families talk openly about illness and end-of-life care significantly improves mental health outcomes for parents and siblings.

Kartläggning av proteinbiomarkörer för patientrapporterade symtom öppnar vägen för precision medicine inom vården. Karolinska Institutet genomför en omfattande scoping review för att koppla självrapporterade symtom till cirkulerande proteinbiomarkörer i blod — en syn som hittills fragmenterats över sjukdomsspecifika studier. Forskarna söker ursprungliga artiklar från PubMed, CINAHL, Embase och Web of Science. En pilotsökning identifierade över 30 000 artiklar, vilket gjorde AI-assisterad screening via ASReview nödvändig för tidseffektivitet. Fem reviewers kommer att extrahera och kartlägga associationer mellan enskilda symtom och proteinmarkörer för att identifiera överordnade biologiska mönster. Resultaten blir relevanta för inköpschefer som evaluerar nya biomarkörplattformar, regulatoriska specialister som bedömer diagnostiska algoritmer, och kliniker som söker evidens för symtombaserad stratifiering. Studien lanseras 2026.

A Swedish study of intensive care nurses reveals deep ethical conflicts when switching patients from life-saving treatment to organ donation protocols.
