The findings suggest the need for improved patient communication and informed consent.
A recent study found that black women are less likely to want to receive kidney transplants from living donors, despite receiving more unsolicited offers from family and friends. Women were also less likely to be evaluated for a transplant, highlighting the need for targeted interventions to alleviate existing disparities.
Fecal microbiota transplantation (FMT) shows promise in treating a broad range of gastrointestinal disorders, including irritable bowel syndrome and inflammatory bowel disease. A new orally delivered community of microbes has been developed to address the challenges of FMT.

A new study published in the American Journal of Transplantation found that older kidney donors experience similar longevity and cardiovascular health as healthy individuals. The research, led by Dr. Peter Reese, suggests that donation does not significantly increase the risk of death or heart disease among older adults.

A recent study published in Liver Transplantation found that obese liver transplant recipients with diabetes experienced higher morbidity rates due to post-transplant complications, particularly diabetes and metabolic syndrome. Despite this, obesity did not negatively affect survival rates.
A study from Brigham and Women's Hospital found that most cardiac implantable electronic devices were approved as changes to existing PMA-approved models without new clinical data. This raises concerns about patient safety, particularly for devices such as the St. Jude Medical Riata and Medtronic Sprint Fidelis defibrillator leads.
A new study reveals substantial geographic variation in waiting times for children needing kidney transplants, with local organ supply and demand affecting outcomes. The findings suggest that a broader geographic sharing of kidneys is necessary to address these disparities.
Researchers from UNSW successfully transplanted Phyllospora comosa onto two barren reef sites in Sydney, where it once thrived. The transplanted species not only survived but also reproduced, creating a potential self-sustaining population and restoring a vital habitat for marine organisms.

Abatacept has been shown to be effective in treating patients with recurrent disease and those at high risk for kidney failure.
A Swedish study reveals that many heart failure patients are undertreated, with high mortality rates associated with poor pump capacity, kidney function, blood count, and lack of ACE inhibitors and beta blockers. The study suggests referring these patients to heart failure specialists for evaluation and treatment.
A study found a pill-based fecal transplant to be effective in stopping recurrent C. diff infections, achieving a 100% success rate among patients. The treatment involves taking capsules containing fecal bacteria, rebalancing the gut microbiome and preventing future infections.
