The finding could reshape how cardiologists monitor millions of patients long-term and trigger reassessment of imaging protocols used to predict outcomes.EN

Men who required assisted reproduction to conceive face elevated risk of non-reproductive cancers compared to those who conceived naturally, according to a Swedish registry analysis of 1.1 million fathers. The finding suggests underlying fertility problems—rather than treatment itself—may drive cancer susceptibility, with implications for screening protocols and fertility clinic counseling.EN

Researchers have identified how exercise triggers an immune molecule called thromboxane that directly enhances glucose absorption in skeletal muscle. The finding opens a potential new therapeutic angle for type 2 diabetes management, potentially allowing clinicians to mimic exercise's metabolic benefits through targeted drug interventions rather than relying solely on lifestyle changes.EN

Researchers discovered that people with diabetes using medical devices have higher rates of contact allergies to certain plant-based compounds than the general population. The finding could reshape how device manufacturers select materials and how clinicians screen diabetic patients for skin reactions.EN

Researchers have for the first time quantified how much of the bacteria-killing work comes from a patient's immune system versus antibiotics alone. The finding could reshape how doctors dose antibiotics—potentially requiring lower doses in some patients while higher doses in others—with major implications for treatment guidelines and drug development.EN

Swedish researchers quantified for the first time how spinal muscular atrophy devastates workplace output through missed work days and premature deaths among working-age adults. The findings provide healthcare systems and employers with concrete economic data to justify investment in treatments and workplace accommodations for this progressive neuromuscular disorder.EN

A Swedish study of 15,000+ patients reveals that transformation risk to leukemia varies sharply by blood disorder type and disease progression timeline—challenging decades of assumptions that age is the primary driver. The findings could reshape treatment monitoring strategies and clinical trial design for myeloproliferative neoplasm patients.EN

Researchers monitoring heart rates of eight horses at a Swedish city park found that visitor presence and playground contact did not trigger stress responses. The finding has implications for zoo operators balancing visitor access with animal welfare concerns—a key factor in breeding programs for endangered species.EN

A 20-center European study of 79 women undergoing pelvic exenteration for vulvar cancer found five-year survival rates of 32%—comparable to other advanced cancers treated similarly. The finding matters: it provides rare real-world evidence to guide whether elderly, often overweight patients should pursue this disfiguring but potentially curative operation.EN

A Swedish study of nearly 450 patients shows that combining short-burst radiotherapy with chemotherapy before surgery cuts the risk of cancer recurrence to under 6% over five years. The findings could reshape treatment protocols across healthcare systems and reduce the need for invasive follow-up interventions in thousands of patients annually.EN

Patients who underwent salvage surgery for anal cancer after failed radiation achieved a 67% five-year survival rate when tumors were completely removed—but just 9% when microscopic cancer remained. The finding, from Sweden's national cancer registry, clarifies which patients benefit from this aggressive but necessary last-resort treatment and could reshape treatment guidelines.EN

A major study of 520 young athletes reveals that men recover stronger muscle function than women after ACL reconstruction, and the type of graft used significantly affects which muscles lag behind. These findings could reshape how surgeons select grafts and tailor rehabilitation plans to prevent long-term athletic performance gaps.EN

A Swedish study of 12,900 workers found that career advancement improves depression symptoms differently across demographic groups: the benefit is strongest for younger women, moderate for older workers of both sexes, and negligible for younger men. For employers and policymakers, the finding suggests that one-size-fits-all mental health interventions miss critical gender and age dynamics affecting workforce wellbeing and productivity.EN

A Swedish study of 78,000 patients finds that 30% continue taking hypnotics for a year or longer after depression diagnosis, raising concerns about dependency and healthcare costs. The findings suggest doctors need clearer guidelines on when to stop prescribing these drugs, as their long-term safety in depression remains contested.EN

Researchers have mapped how DNA modifications change in atopic dermatitis, revealing a breakdown in communication between immune and skin barrier cells. The findings could reshape how companies develop targeted eczema treatments and help identify patients who will respond best to specific therapies.EN

A new study comparing reusable and disposable surgical clothing found that single-use scrubs reduce dangerous bioparticles in operating room air by roughly 50%, while staff numbers and surgery length had no effect. The finding could reshape hospital purchasing decisions and infection control protocols, particularly for joint replacement procedures where surgical site infections carry significant costs and patient risks.EN

A Swedish study of nearly 300,000 people with prior fractures reveals that immigrant men are significantly less likely to suffer repeat breaks, while immigrant women match native rates. The findings suggest bone health interventions may need tailoring by population origin—a critical insight for healthcare systems serving diverse immigrant populations.EN

European medical societies have issued the first consensus guidelines for diagnosing and treating bone fragility in chronic kidney disease patients, establishing which blood tests should guide treatment decisions. The move addresses a major gap in clinical practice and could improve outcomes for millions of CKD patients at risk of fractures.EN

Researchers have developed a simple one-step method to synthesize hard-to-find fatty acid metabolites called octadecanoids, removing a major bottleneck in studying their health effects. The breakthrough could accelerate drug discovery for inflammation, immune disorders, and metabolic diseases while opening new markets for pharmaceutical manufacturers and supplement makers.EN

A new study tracking Swedish workers over a decade reveals that newer generations experience higher job demands, less control, and worse stress levels than their older counterparts—a troubling pattern that defies the country's reputation for workplace quality. The findings suggest generational workplace conditions are deteriorating, with implications for productivity, healthcare costs, and talent retention across Nordic employers.EN

Swedish researchers tracking over 1,000 infants with confirmed neonatal seizures found significantly elevated risks for developmental delays, autism, ADHD, and cerebral palsy in childhood. The findings suggest healthcare systems need longer-term monitoring protocols for affected newborns and may reshape how hospitals allocate resources for early intervention services.EN

Researchers have pinpointed apolipoprotein C-III as a key driver of dangerous triglyceride buildup and arterial inflammation. Blocking this protein with new antisense drugs shows promise in clinical trials, potentially offering a major new treatment for millions at cardiovascular risk—especially those with diabetes.EN

KBT visar långsiktig effekt för tvångsstörning — återhämtningsgraden stiger från 48 procent vid avslutad behandling till 52 procent vid uppföljning cirka två och ett halvt år senare. En metaanalys av 47 studier med sammanlagt 2 817 patienter visar att både exponerings- och responsprevention, kognitiv terapi och kombinerad behandling ger mycket stora effektstorlekar utan inbördes skillnad. Responsgraden ligger stabil på cirka 70 procent. Barn och ungdomar uppvisar fortsatt förbättring under uppföljningsperioden medan vuxnas effekter bibehålls på samma nivå. Stockholm University och Karolinska Institutet ledde arbetet tillsammans med norska forskare. För regionvården är resultaten relevanta vid bedömning av långsiktiga behandlingsresultat för tvångsstörning. En initialt stor förändring av tvångsintensiteten under behandling förutspår starkare långtidseffekter, vilket kan vägleda patientval och uppföljningsintensitet.
