For patients who need a liver transplant, determining whether a donor liver is healthy enough to transplant is a critical part of the process. https://medicalxpress.com/news/2026-07-real-biosensor-ph-glucose-lactate.html Tue, 14 Jul 2026 12:00:03 EDT news703245699 Each year, thousands of patients in the United States wait for a liver transplant, while transplant teams must make rapid, difficult decisions about whether donor organs are suitable for use. Many of those livers, particularly from older or medically complex donors, require careful evaluation before transplantation, and current assessments often sample only a small region of the organ. https://medicalxpress.com/news/2026-07-portable-ps-oct-scanner-reveal.html Wed, 08 Jul 2026 18:00:07 EDT news702741466 A landmark Northwestern Medicine study published in JAMA suggests lung transplantation can significantly extend survival in select patients with advanced lung cancer. https://medicalxpress.com/news/2026-07-lung-transplant-survival-patients-terminal.html Wed, 08 Jul 2026 15:20:03 EDT news702737704 For the first time, two teleoperated humanoid robots have been used to complete two surgeries during a preclinical trial, researchers report in the July 8 issue of the journal Nature. The work is the result of a collaboration between a team of engineers and a team of surgeons at the University of California San Diego. https://medicalxpress.com/news/2026-07-surgeons-teleoperated-humanoid-robots-surgery.html Wed, 08 Jul 2026 14:40:04 EDT news702729363 A liver cancer diagnosis frequently leads to surgery, with the goal of completely removing all malignant tissue. To ensure that no tumor remains in the organ, the resected tissue is subjected to frozen-section analysis during the procedure. This analysis takes time: Patients remain under general anesthesia throughout, operating room staff are occupied, and with every passing minute the risk of complications increases. https://medicalxpress.com/news/2026-06-ai-based-tissue-anomaly-duration.html Mon, 22 Jun 2026 15:20:03 EDT news701358601 A study led by researchers at Children's Hospital of Philadelphia (CHOP) demonstrates a new method of using decellularized cartilage with patient-specific cells to help enlarge pediatric airways narrowed as a result of severe subglottic stenosis. Researchers demonstrate that this new method is faster, more effective and able to overcome issues associated with the current standard grafts, such as donor site morbidity, insufficient tissue volume and a delayed timeline. The findings are published in the journal Nature Communications. https://medicalxpress.com/news/2026-06-scientists-personalized-cartilage-graft-infants.html Wed, 17 Jun 2026 05:00:05 EDT news700744261 Metabolic and bariatric surgery for teens with severe obesity was found to be cost-effective over 10 years, according to a new analysis from Ann & Robert H. Lurie Children's Hospital of Chicago published in JAMA Network Open. While long-term clinical benefits of weight-loss surgery for eligible teens have been well established, and it is recommended by the American Academy of Pediatrics, insurance coverage has been limited and few teens can take advantage of the surgery. https://medicalxpress.com/news/2026-06-economic-case-teen-weight-loss.html Mon, 15 Jun 2026 11:00:14 EDT news700730821 Skin is our protective barrier from the outside world, and it is highly susceptible to damage. To prevent infection, restore protective skin cells, and reduce scarring, it is essential to quickly and robustly close a wound. A new study, published in Advanced Science, shows that a multi-axis stretchable wound zipper (MSWZ) is effective in closing complex wounds quickly, improving wound healing. The MSWZ uses programmable force that can be personalized via mobile application, enhancing patient comfort and compliance. https://medicalxpress.com/news/2026-06-programmable-wound-zipper-complex-skin.html Thu, 11 Jun 2026 03:10:01 EDT news700299601 A landmark clinical trial published in the New England Journal of Medicine found that tranexamic acid reduced transfusions across major surgeries without increasing the risk of dangerous blood clots. The trial was coordinated by the University of Manitoba (UM) and co-led by researchers at UM and The Ottawa Hospital. https://medicalxpress.com/news/2026-06-inexpensive-drug-major-surgeries-blood.html Wed, 10 Jun 2026 08:30:01 EDT news700216081 A pioneering clinical trial has successfully enabled two patients with end-stage kidney disease to receive previously improbable kidney transplants. These individuals were considered among the most difficult in the nation to match with a compatible donor kidney due to harmful antibodies they had developed ("sensitized"). https://medicalxpress.com/news/2026-06-car-treatment-door-patients-kidney.html Wed, 03 Jun 2026 17:00:05 EDT news699715466 Each year, about 250,000 Americans undergo sleeve gastrectomy, one of the most common weight-loss operations in the United States. For most patients, recovery is uneventful. But for a small share—between 1% and 3% in routine cases, and as many as 1 in 10 in revision surgeries—the procedure can leave behind a gastric leak, in which fluid escapes from the stomach and forms an abscess. https://medicalxpress.com/news/2026-06-3d-stent-lily-recovery-weight.html Wed, 03 Jun 2026 13:00:07 EDT news699708962 Tissue expansion is a common technique used in reconstructive surgery. Surgeons slowly stretch nearby skin to grow extra tissue that can be used to rebuild areas such as the ear, breast, or nose. https://medicalxpress.com/news/2026-06-custom-4d-implants-painful-path.html Tue, 02 Jun 2026 11:40:05 EDT news699617641 A nationwide study has shed new light on how to most effectively and safely treat Chiari malformation and syringomyelia, rare neurological diseases that impact both children and young adults. https://medicalxpress.com/news/2026-05-chiari-malformation-syringomyelia-treatment-large.html Wed, 27 May 2026 17:00:02 EDT news699102841 A simple blood test could one day replace invasive biopsies for detecting acute cellular rejection (ACR) after lung transplantation, an American Journal of Transplantation study finds. https://medicalxpress.com/news/2026-05-blood-lung-transplant.html Wed, 27 May 2026 16:20:07 EDT news699110822 Metabolic/bariatric surgery is a highly effective treatment for people living with severe obesity and/or metabolic health conditions, which works through changing the anatomy of the digestive system and thereby changing the way it functions and the hormones it produces. Procedures include the sleeve gastrectomy and gastric bypass. https://medicalxpress.com/news/2026-05-weight-loss-drug-semaglutide-patients.html Fri, 22 May 2026 12:00:06 EDT news698667362
