New technique improves outcome for living donor liver transplants

The University of Alberta Hospital (UAH) is one of only a few centers in Canada that perform living donor liver transplantation, a surgical procedure developed in the late 1980s that expands the organ donor pool. About 80 liver transplants are done a year in Alberta, 10 of those being living-donor.

New interventional radiology treatment shows promise for complications from bone marrow, stem cell tranplants

The standard treatment to treat graft-versus-host disease (GVHD) after bone marrow or cord blood transplant is intravenous (IV) steroids that alter the immune response; however, it is not always effective and failure results in very high mortality.

Variants of the gene LRP5 associated with increased risk of bone fractures, low bone mineral density

Results from a large study indicate that variants of the gene LRP5 are associated with a significant increase in the risk of fractures, by up to 20 percent, and lower levels of bone mineral density in the spine and hip, according to a study in the March 19 issue of JAMA, a theme issue on Genetics and Genomics.

Most women unaware of uterine fibroid embolization

A study presented at the Society of Interventional Radiology's 33rd Annual Scientific Meeting shows of 105 patients in the Atlanta metro area, only 18 percent of the women who saw a private practice gynecologist were told about uterine fibroid embolization (UFE), a minimally invasive treatment for uterine fibroids provided by interventional radiologists.

First clinical trial data of a fully bioabsorbable drug-eluting stent

Data published today in The Lancet from ABSORB, the world's first clinical trial of a fully bioabsorbable drug eluting stent for the treatment of coronary artery disease, demonstrated no stent thrombosis, no clinically driven target lesion revascularizations (re-treatment of a diseased lesion), and a low (3.3 percent) rate of major adverse cardiac events (MACE) in 30 patients out to one year.
