Despite strong curricula, Nepal's midwifery programs fail to adequately train providers in emergency childbirth skills and don't align training with available jobs, a new analysis shows. The findings reveal a critical disconnect: even as the country has slashed maternal death rates, the quality of care remains constrained by education gaps that could undermine further progress.EN

Selektiva COX-2-hämmare kan användas försiktigt vid muskelskeletala smärtor hos IBD-patienter i remission, enligt en ny granskning från Örebro universitet. Två randomiserade placebo-kontrollerade studier visade ingen högre risk för IBD-återfall eller symtomaggrävering under kortvarig behandling, bland annat hos patienter med ulcerös kolit i remission och IBD med reumatiska manifestationer. Öppna studier rapporterade varierande gastrointestinala biverkningar och ibland symtomaggrävering, men studiepopulationerna och uppföljningstiderna skiljde sig väsentligt. Forskare från Örebro universitets medicinska fakultet konstaterar att evidensbasen är begränsad. För praktisk tillämpning rekommenderas tidsbegränsad behandling med lägsta effektiv dos och klinisk övervakning. Resultaten vägleder inköpschefer och chefsläkare vid val av analgetika för denna patientgrupp, där både smärtlindring och tarmsäkerhet måste vägas.

A simple intervention—assigning a nurse to develop personalized care plans for people who repeatedly call emergency dispatch—reduced their ambulance requests by two-thirds and emergency contacts by more than half. The findings suggest healthcare systems can save money and improve outcomes by addressing the underlying needs of their most costly frequent users.EN

A new analysis of 24 years of Swedish housing data upends conventional wisdom about renovictions: it's not low-income tenants fleeing renovated buildings, but wealthier renters departing—while disadvantaged households get trapped. The finding suggests housing scarcity, not renovations alone, drives displacement patterns that policy makers should address.EN

A study of over 3,000 water damage incidents across Swedish municipal buildings reveals widespread failures in pipes, appliances, and building systems—with schools and care facilities bearing the highest costs. The findings expose a major operational and budget risk that public administrators have largely tracked informally, hampering prevention efforts.EN

Researchers tracked 1,610 chronic hepatitis D patients and found that 8.4% achieved spontaneous viral suppression over four years—a rare outcome that was more likely in diabetic men with lower initial viral loads. The findings could help doctors identify which patients might recover without treatment, potentially reducing unnecessary interventions and healthcare costs.EN

Swedish researchers discovered that doctoral students want different things from their supervisors depending on where they are in their studies—a finding that could reshape how universities train advisors and support early-career researchers. The insights suggest institutions need flexible supervision models rather than one-size-fits-all approaches to improve retention and research quality.EN

A Swedish study of 61,000 bipolar patients found the condition dramatically increases risk for dementia, sleep disorders, and type 2 diabetes—but not type 1 diabetes. The findings suggest healthcare systems and insurers need integrated physical and mental health screening protocols, potentially reducing costly emergency interventions and improving long-term patient outcomes.EN

A correction to a study on tetralogy of Fallot clarifies how electrical changes in the heart relate to surgical repair timing and outcomes. The finding matters for cardiologists planning interventions and hospitals managing pediatric cardiac surgery programs.EN

A major trial tracking 539 patients for three years found that immunocompromised individuals—including cancer and transplant patients—develop durable immune protection against COVID-19 through vaccination and infection. The findings could reshape how healthcare systems manage long-term vaccine strategies for vulnerable populations and inform future pandemic preparedness policies.EN

A study of Zimbabwe's donor-funded retention scheme finds that financial incentives cannot close the wage gap driving health worker migration to wealthier nations. The finding challenges a common policy tool and raises questions about whether low-income countries can retain medical talent without systemic economic reform.EN

A new study of Somali-born women in Sweden reveals that healthcare providers often ignore patients' cultural values, family dynamics, and personal preferences when prescribing birth control. The findings suggest clinics risk poor outcomes—and legal exposure—by failing to adapt services to diverse populations, a growing challenge across Europe's immigration-dependent healthcare systems.EN

Researchers tracked how quickly transplant patients develop dry mouth and salivary gland damage—a common but serious long-term complication. The findings could help clinicians identify at-risk patients earlier and guide treatment decisions for the 50,000+ Americans receiving bone marrow transplants annually.EN

A study of 190 flatfoot surgery patients in Sweden found significant improvements in foot function and satisfaction one year after treatment, with 77% of patients satisfied with their foot appearance post-surgery compared to 39% before. The findings provide rare real-world evidence on surgical effectiveness, offering clinicians and healthcare systems concrete data for treatment planning and resource allocation.EN

Researchers have demonstrated that ultra-high-frequency ultrasound can reliably distinguish healthy from diseased bowel tissue during surgery for Hirschsprung disease, a congenital condition affecting infants.
