A new review of return-to-sport protocols reveals wide gaps in how doctors decide when injured athletes can resume play after shoulder surgery. With test pass rates varying wildly—from 28% to 100%—sports medicine lacks standardized benchmarks, leaving teams and insurers without reliable guidance on injury readiness and liability risk.EN

A new analysis of Swedish primary care reveals that moving GPs to salaried positions and team-based models—touted as solutions to recruitment crises—may actually increase turnover rates. The finding suggests policymakers need to rethink how they retain doctors in primary care, with significant implications for healthcare systems worldwide facing GP shortages.EN

Researchers have identified a specific pattern of 195 proteins in urine that reliably distinguishes long COVID patients from healthy controls, with 96% accuracy in testing.

**Tampa-skalan fungerar dåligt för att bedöma skadoresultanter utan smärta** Tampa Scale of Kinesiophobia (TSK) är utbredd för att mäta rädsla för återskada hos idrottare efter ACL-rekonstruktion, men skalan utvecklades ursprungligen för smärtrelaterad fobisk undvikande. Umeå universitet och Högskolan i Gävle testade skalans giltighet på 92 ACL-skadade med och utan smärta. Resultaten visar allvarliga psykometriska brister: smärtspecifika TSK-frågor dominerade totalpoängen (rs=0,85), vilket snedvred bedömningen. Det ursprungligen rekommenderade gränsvärdet (38 poäng) gav låg känslighet (sensitivitet 27,5%). Ett nytt gränsvärde på 33,5 förbättrade känsligheten till 70,6 procent, men TSK visade dålig överensstämmelse med psykologisk beredskapsindex (ACL-RSI). För kliniker och inköpschefer innebär detta: validera TSK inte direkt för återskadebedömning utan smärta. Alternativa skattningsverktyg eller justering av tolkningen är nödvändig för korrekt riskvärdering före återgång till sport.

A two-country study finds that digestive disorders linked to stress and anxiety jumped from 38% to 43% of the population between 2017 and 2023. The shift signals growing demand for mental health integration in gastroenterology care and represents a substantial market expansion for treatments addressing these conditions.EN

A new study of substance abuse treatment clinics reveals that organizational support significantly reduces how difficult clinicians find their daily work with youth struggling with mental health and addiction issues. The finding matters because clinician burnout drives costly staff turnover and compromises treatment quality—suggesting that better workplace support could be a practical lever for improving retention and care outcomes.EN

Adults who survived moderate to severe congenital heart disease show no greater cognitive decline or physical frailty than people their age without the condition, according to new research.
