A randomized trial of medical students learning laparoscopic surgery found that real-time instructor oversight provided no performance advantage over independent practice. The finding could reshape how surgical training programs allocate resources and instructor time, potentially freeing experts to supervise more advanced procedures while novices self-direct foundational skills.EN

A new Swedish study of 343 pancreatic cancer patients found that those whose cancer returns only to the lungs survive nearly 2.5 times longer than those with liver recurrence. The finding could reshape post-surgery monitoring and treatment decisions, potentially reducing unnecessary aggressive interventions for patients with favorable recurrence patterns.EN

A study of older adults testing an AI-powered mindfulness assistant revealed a critical tension: while they appreciated personalized guidance, they feared the technology would erode human relationships and their own self-reliance. The findings signal that wellness tech companies targeting aging populations must design for autonomy, not dependency.EN

Robots deployed in public spaces lack basic social awareness, causing navigation conflicts that slow foot traffic and confuse travelers. Researchers analyzing video footage at a major airport argue that designing robots to understand human movement patterns—not just floor obstacles—is essential for smooth operations and passenger experience.EN

A new study of workers paired with collaborative robots reveals a dangerous gap: when machines malfunction, people notice the problem but rarely know what to do about it. Half respond productively with fixes or questions; half resort to sarcasm, jokes, or errors that worsen the situation—a finding that has serious implications for workplace safety and the viability of human-robot teams in manufacturing and logistics.EN

Researchers have created a practical tool for product developers and policymakers to better understand how menstrual technologies affect—and are affected by—family, workplace, healthcare systems, and culture. The framework, tested with experts, reveals that successful menstrual products require thinking beyond the individual user to the entire ecosystem shaping their choices.EN

A large Swedish study debunks the widespread belief that computer work causes skin problems, finding no visible skin damage in VDU workers despite their complaints. The research matters for workplace health policy and occupational medicine, potentially reducing costly, unnecessary dermatological referrals and reassuring employers about screen-based work safety.EN

Researchers have engineered a system to reprogram immune cells directly in patients rather than in expensive manufacturing facilities, potentially making CAR-T cell therapies faster and more affordable. The technique uses two viruses to deliver gene-editing tools that stably integrate cancer-fighting instructions into T cells in vivo, addressing a major cost and access barrier in cell-based medicine.EN

**Kombinationskador på tänder utgör okänd del av tandtraumaprevalensen** Tandtraumapatienternas faktiska skadebörda är högre än statistiken visar — många drabbas av flera skador samtidigt på samma tand, men detta dokumenteras sällan i kliniken. En metaanalys från Karolinska Institutet samlade 30 observationsstudier från 20 länder för att kartlägga kombinationskadors omfattning bland 34 382 traumatiserade permanenta tänder. Resultatet visar att 14 procent av tandtrauman utgörs av kombinationsskador, med en spännvidd från 2 till 48 procent mellan studier. Danmark rapporterade högast prevalens. De vanligaste kombinationerna var emailj-dentinfraktur tillsammans med subluxation (25 procent) och emailj-dentinfraktur med commotio (17 procent). För inköpschefer och regionala tandvårdsprogram innebär detta att klassificeringssystem och behandlingsprotokoll måste uppdateras för att fånga denna ofta överseende skadekategori, vilket påverkar resurallokering och patientprognos.

Hälsovårdens spelberoendestöd saknar strukturerade vägar mellan spelplattformar och behandling. En systematisk granskning från Karolinska Institutet och Stockholm Health Care Services analyserade 39 studier från 2014–2024 och identifierade tio kärnproblem i remissvägar och behandlingskontinuitet för spelbetingad skada. Studierna visar att få spelplattformar har formaliserade överföringsmöjligheter till sjukvård. Ansvarsfördeln mellan speloperatörer, hälsovård och stödsystem påverkar institutionernas beredskap att upptäcka och agera på spelberoende. Barriererna ligger på antecedent-, besluts- och resultatnivå: från dålig tjänstesyn och systemunderberedskap, via gatekeepers roll vid remiss, till trattkav under behandling. Regelverken måste adressera referensstrukturer mellan spelnäringen och vårdgivare. För inköpschefer inom region blir detta aktuellt när man utvärderar vårdsystemets beredskap för tilltagande spelberoende—implementering av organiserade remissvägar kan reducera behandlingsfördröjning och förbättra uppföljning.

Interaktiv social kontakt under tidig utveckling förändrar hjärnans struktur på ett sätt som passiv skärmexponering inte kan ersätta. Forskare vid Stockholms universitet och University of British Columbia uppfödde guppor under tre förhållanden: direkt socialt umgänge med artfränder, filmad social exponering via skärm eller minimal social kontakt. Resultaten visade att fiskar med faktisk social interaktion utvecklade signifikant större relativ hjärnstorlek och större luktlober jämfört med båda övriga grupper, som blev lika små. Kognitiv prestanda skilde sig dock inte mellan grupperna. Studien etablerar att interaktivitet — inte blotta närvaron av sociala stimuli — driver neurologisk utveckling. För barn- och ungdomsmedicin har detta implikationer för rekommendationer kring skärmtid. För MedTech-sektorn öppnas möjligheter för neuroplasticitetsmål i digitala interventioner. Normen för utvecklingsstöd måste kombinera direktkontakt med teknologi, inte ersätta det ena med det andra.

**Träning tre gånger per vecka eliminerar diabetesrelaterad strokeökning** Människor med typ 2-diabetes har 36 procent högre risk för ischemisk stroke än friska personer — men regelbunden fysisk aktivitet helt tar bort denna överrisk. En nationell svensk populationsstudie med 369 704 diabetespatienter och över 1,1 miljoner kontrollpersoner visar att patienter som tränar minst tre gånger i veckan uppnår strokeincidenser motsvarande icke-diabetiker i samma ålder och kön. Studien, genomförd via Svenska diabetesregistret 2010–2019, mätte aktivitetsnivåer och strokeförekomst med Cox-regressionsmodeller. Högre fysisk aktivitet reducerade även strokerisken vid höga blodsocker-värden. För regional vård och inköpsenheter förändras detta prioriteringen av diabetesomsorgen: träningsprogram blir preventiv medicinsk insats, inte tilläggsöversättning. Universitet Göteborg och Sahlgrenskas register dokumenterar bevis för regulatoriskImplementering av aktivitetsbaserad strokepreventionsstrategi.

A randomized trial of transcutaneous electrical nerve stimulation (TENS) found no benefit over placebo for managing osteoarthritis pain or improving activity levels in dogs. The negative result challenges assumptions about this non-drug treatment and suggests pet owners and veterinarians need better alternatives for chronic pain management in animals.EN

A rigorous clinical trial shows that subperception dorsal root ganglion stimulation—a minimally invasive implant that sends electrical pulses to nerve clusters—significantly reduces chronic nerve pain without causing sensation. The finding validates a growing market for implantable pain devices and provides insurers and hospital systems with rare, gold-standard evidence for reimbursement decisions.EN

A Swedish study reveals that doctoral candidates working in industry-academia partnerships lack training to communicate their findings to both audiences—a gap that threatens the promise of these programs to bridge business and university innovation. Without better support, universities risk failing to produce researchers who can effectively transfer knowledge where it matters most.EN

New research documents the full spectrum of physical health problems affecting bipolar patients, from cardiovascular disease to metabolic disorders. Understanding these comorbidities matters for healthcare systems and insurers planning treatment costs and outcomes management across psychiatric populations.EN

A review of 500 disciplinary cases shows that 87% of complaints against veterinarians don't result in sanctions—but the majority involve poor communication and perceived lack of empathy, not clinical errors. The finding suggests veterinary practices and regulators must invest equally in soft skills and clinical training to reduce complaints and build owner trust.EN

A kidney transplant patient who developed cancer originating from the donor organ was successfully managed with checkpoint inhibitors instead of organ removal, according to a new case report. The finding suggests immunotherapy may offer an alternative pathway for treating rare but serious donor-transmitted cancers, potentially expanding treatment options for transplant recipients facing this complication.EN

Researchers have validated a telemetric monitoring system that tracks fluid pressure in the spine during spaceflight—a breakthrough that could finally explain why astronauts experience vision problems in microgravity. The technology opens a path to preventing a costly health risk that currently limits long-duration missions and crew safety.EN

A Swedish study of 1,900 people found that women eating the healthiest diets were prescribed blood pressure medications nearly 2.5 times faster than those with poor diets—suggesting doctors may be more aggressive in treating high-risk patients who take health seriously. The counterintuitive finding challenges assumptions about lifestyle-medicine tradeoffs and could reshape how insurers and physicians approach preventive cardiology.EN

A Swedish study of 473 women with breast sarcomas found that those with higher education and income lived longer, even within a universal healthcare system. The finding suggests that socioeconomic factors—beyond access to treatment—shape cancer outcomes, raising questions about how health systems can level the playing field.EN

Scientists discovered why estrildid finches resist ovarian hyperstimulation syndrome despite carrying a genetic mutation that triggers the condition in humans. By studying the birds' natural defense mechanism, researchers identified a drug target—a hormone receptor antagonist—that could prevent this serious complication in fertility treatments, potentially expanding access to safe IVF.EN

A comprehensive marketing ban reduced adolescent intoxication rates in Lithuania compared to peers across other EU nations, according to new research.
