A new study found that liver transplant centers in highly competitive geographic areas performed more transplants than those in less competitive areas. The researchers used data from 53,156 adult liver transplantation operations performed between 2003 and 2012.
Researchers identify Enterococcus faecalis as primary microbial culprit behind post-surgical colon leaks. The bacteria degrades intestinal connective tissues and activates enzymes that cause small holes in the intestine during healing, leading to leaks. Identifying E. faecalis could lead to more effective ways to reduce leak rates.
A study found that wound healing and lower plasma viral loads are associated with less HIV shedding from male circumcision wounds. The likelihood of viral shedding increases initially but decreases as wounds heal.
