Oxygen Perfusion (Persufflation) of Human Pancreata Enhances Insulin Secretion and Attenuates Islet Proinflammatory Signaling.

Background: All human islets used in research and for the clinical treatment of diabetes are subject to ischemic damage during pancreas procurement, preservation, and islet isolation. A major factor influencing islet function is exposure of pancreata to cold ischemia during unavoidable windows of preservation by static cold storage (SCS). Improved preservation methods may prevent this functional deterioration.

Submaximal cardiopulmonary exercise testing predicts 90-day survival after liver transplantation.

Liver transplantation has a significant early postoperative mortality rate. An accurate preoperative assessment is essential for minimizing mortality and optimizing limited donor organ resources. This study assessed the feasibility of preoperative submaximal cardiopulmonary exercise testing (CPET) for determining the cardiopulmonary reserve in patients being assessed for liver transplantation and its potential for predicting 90-day posttransplant survival.
