Psykosocial insatser för allvarlig psykisk sjukdom (SMI) kan omfördela vårdkostnader från specialiserad psykiatri mot primärvård — en förändring som kan rationalisera resurserna utan att öka totalkostnaden. En svensk studie från Lund University och Sahlgrenska följde 77 patienter under och efter ett sex månader långt interventionsprogram (MINT). Forskarna mätte direkta kostnader för sjukvård, socialtjänst och rättsvård med RUMI-instrumentet. Resultatet visar att kostnaderna för fysisk och psykiatrisk vård minskade både under och efter interventionen, medan primärvårdsbesöken förändrades differentierat — läkarbesök minskade men sjuksköterskebesök ökade. Socialtjänstens kostnader förblev oförändrade. För regionala inköpschefer och chefsläkare innebär detta underlag för att omstrukturera vårdkedjan: MINT-liknande program kan flytta upp vården utan att belasta totalkostnaden permanent, givet rätt bemanning i primärvården.

NephroNet möjliggör tillförlitlig automatiserad klassificering av njurpatologi på CT-bilder — ett kritiskt behov då befintliga AI-modeller ofta lider av kalibreringsfel och dataleakage mellan patientbilder. Forskarna från Xi'an Jiaotong-Liverpool University och Stockholm University utvecklade en kompakt neuralnätverksmodell (1,46 miljoner parametrar) tränad på 12 446 bilder från multicenter-kohort för att skilja mellan normal vävnad, cystor, tumörer och stenar. Modellen uppnådde 99,97 procent noggrannhet och ECE-värde på 0,0021, vilket indikerar stark sannolikhetskalibrering — en förutsättning för klinisk tillit. Transparenta tränings- och valideringssplit samt explicit rapportering av osäkerhet stödjer reproducerbar jämförelse mellan kliniska IT-system. Begränsningen är att data kommer från en region, så extern validering återstår innan inköp för regionvårdens bildanalysplattformar kan rekommenderas.

Psykedeliska substanser väcker intresse som potentiell behandling för ADHD, men en systemativ granskning från Karolinska Institutet och King's College London visar att evidensbasen är för svag för kliniska rekommendationer. Forskarna analyserade 1 023 studier och inkluderade sex uppfyllande kriterier: en randomiserad kontrollerad försök fann ingen signifikant effekt jämfört med placebo, tre tvärsnittsstudier rapporterade positiv effekt utifrån patientbeskrivningar, och en mätning med Child Bipolar Questionnaire visade förbättring. En fallrapport dokumenterade att ketamin förbättrade både depressiva symtom och funktion. Studierna löser inte kritiska frågor: det är okänt om ketaminrespondenter faktiskt hade ADHD, och ingen forskning undersökte effekter på patientundergrupper med olika orsaker till symptom. Resultaten pekar på behovet av väl utformade kliniska försök innan psykedelika kan värderas för regulatorisk godkännande eller inköpsbeslut inom regionvården.

Researchers found that children carrying a single copy of the β-thalassaemia gene face significantly higher rates of severe anemia requiring hospital care—a finding that could reshape screening and treatment protocols across sub-Saharan Africa. The discovery complicates the assumption that the genetic variant offers net health benefits by protecting against malaria.EN

Researchers found that four commonly used mouse models of lupus activate distinct molecular pathways, suggesting results from one model may not predict human outcomes. The discovery could reshape how biotech and pharma companies design lupus drug trials, potentially reducing expensive late-stage failures by better matching preclinical work to actual patient biology.EN

Researchers have refined a prediction model that more accurately identifies which men with prostate cancer can safely skip aggressive treatment and opt for monitoring instead.

A new study reveals that Sweden's 2013 palliative care guidelines have failed to shift where terminally ill cancer patients die, with hospitals remaining the dominant place of death rather than patients' homes. Regional disparities persist, suggesting governance gaps are leaving healthcare systems unprepared to deliver end-of-life care equitably—a finding with implications for how countries organize oncology services.EN

Swedish researchers have validated a brief assessment tool that clinics can use to quickly spot family caregivers struggling with anxiety and depression. The finding matters because overwhelmed caregivers often miss work and generate hidden healthcare costs—early intervention could reduce both.EN

Swedish researchers tracking 11,000 adults found that depressive symptoms significantly increase the risk of atherosclerotic heart disease, even accounting for traditional risk factors.
