A Norwegian hospital study of 3,400 patients finds that D-dimer blood tests remain reliable even when patients report symptoms lasting weeks—contradicting guidance that labs should skip the test in these cases. The finding could reduce unnecessary imaging costs and speed up diagnosis of life-threatening blood clots.EN

Researchers found that adults experiencing stress-related exhaustion are significantly more likely to report emotional neglect in childhood, though other trauma types showed no connection. The finding could reshape how employers and health systems identify and support workers at highest risk of burnout.EN

Researchers developed an AI system that predicts Type 2 diabetes with 95% accuracy by analyzing patient data, potentially catching millions of undiagnosed cases early. The advance could reshape diabetes screening programs and reduce costly complications, though healthcare systems must first address how to implement and scale the technology widely.EN

A global survey of 617 surgeons reveals wide disagreement on when to use staging laparoscopy to detect hidden tumors in pancreatic cancer patients before major surgery. The practice ranges from 59% adoption in Africa to 90% in the Americas, signaling that clinical guidelines remain too vague to drive consistent treatment decisions across hospitals and regions.EN

A large US study found that children born with VACTERL—a cluster of congenital defects affecting the spine, heart, and other organs—are three times more likely to develop cancer before age 18, with embryonal tumors being seven times more common. The finding suggests doctors may need to implement stronger screening protocols and could reshape treatment guidelines for the estimated 2,300 affected children born annually in the US.EN

Post-COVID-19-trötthet (PCC) förblir en diagnostisk utmaning utan etablerad patofysiologisk förklaring — ett problem som försvårar både patienthantering och resurstilldelning i regionvård. En interdisciplinär studie från Linköpings universitet kombinerar fenomenologisk analys av patientupplevelser med neurologiska mätningar och blodprover för att kartlägga trötthetens affektiva dimensioner. Forskargruppen identifierade fyra distinkta upplevelsemönster: oförmåga att engagera sig trots vilja, försvunnen affektiv dragning, anfallsartad känsla och upplevelse av att vara "i en bubbla". Resultaten kopplade dessa fenomenologiska mönster till hjärnbildning och inflammationsmarkörer. Studien är relevant för regionala rehabiliteringsteam och inköpsansvariga då den erbjuder ett ramverk för att identifiera subtyper av PCC-trötthet som konventionell klinisk bedömning missar — väsentligt för att utforma riktade interventioner och optimera patientvårdsvägen.

Swedish researchers tracking 1,062 extremely premature infants born at 22-26 weeks found significant improvements in neurodevelopmental health between 2004-2007 and 2014-2016 cohorts. The findings suggest advances in neonatal care are translating into better long-term outcomes—critical data for healthcare systems evaluating intensive care investments and family support policies.EN

Researchers have developed a method to translate findings from narrow clinical trials into predictions for broader patient populations. The approach, demonstrated with a heart attack prevention study, could help hospitals and policymakers make better treatment decisions by accounting for the differences between trial participants and actual patients they treat.EN

Researchers tracking over 4,800 adults for two years found that depression isn't always stable—for some people, symptoms worsen predictably in summer or winter, while their self-care habits collapse during those periods. The finding could reshape how employers and health systems support workers and design preventative interventions.EN

A new study shows that the initial position of a torn hamstring tendon on MRI scans can forecast whether a patient will experience significant muscle deterioration months later, even with conservative treatment. The finding could help clinicians decide which patients need surgery versus rest, potentially saving costs and improving recovery outcomes.EN

A decade-long trial shows that a multidisciplinary treatment program combining therapy with medical assessment reduces work absences significantly for employees with depression, anxiety, or chronic pain. The finding matters to employers and insurers managing disability costs and workforce productivity.EN

Adopting a Paleolithic-style diet—heavy on meat, fish, vegetables, and nuts—significantly reduces chronic inflammatory markers linked to heart disease and early death, according to a 23,000-person Swedish study. The finding could reshape how insurers, employers, and health systems approach preventive nutrition, potentially reducing costly cardiometabolic diseases before they develop.EN

Norwegian and Swedish researchers found that students experience grades as both powerful motivators and sources of demotivation, depending on which aspect of grading they emphasize. The finding suggests that schools cannot assume a one-size-fits-all grading policy will drive achievement, and that curriculum designers should understand emotional and psychological impacts alongside academic metrics.EN

A 10-year study of 181 aging polio survivors reveals significant deterioration in muscle strength, fatigue, and mobility—findings that could reshape care planning and public health resource allocation for this aging population. As polio survivors enter their 80s, understanding these progressive impairments is critical for healthcare systems planning long-term care infrastructure.EN

A comprehensive analysis of anxiety and depression across Ghana reveals how social factors—poverty, education, employment—drive mental illness rates. For policymakers and employers, the findings suggest that mental health interventions must target underlying inequalities to be effective, not just clinical treatment.EN

A new study of IgA nephropathy—a common cause of kidney failure—reveals that the same disease operates through fundamentally different molecular mechanisms in children and adults. The finding could reshape how doctors diagnose and treat patients, potentially enabling age-tailored therapies where one-size-fits-all approaches have failed.EN

A Swedish study tracking a decade of prescription data found that only 3% of epilepsy patients adopted five newer antiseizure medications, even after regulatory approval.
