Nowadays organ transplantation is a life-saving procedure, or anyhow it can considerably improve the life quality of patients suffering from irreversible organ impairment. Monitoring transplantation outcome is the last step of a long process that starts with cadaver donor identification, selection and clinical management, and continues with organ allocation, patient evaluation, surgical operation and clinical follow-up. The National Transplantation Committee has been discussing many of these items and, in 1995, it set up two protocols, one on liver exchange for urgent patients and the other on transplantation in the pediatric patient. The protocols application has met many difficulties, mainly due to the uneven behaviours of the different inter-regional organizations. In this paper we comment on the two main aspects to be submitted to the next National Committee: organ allocation and transplantation outcome. As far as the last point is concerned, the enclosed data are based on the experience of the North Italy Transplant program (NITp), and on that of the major international registries. Without any doubt these data demontrate that organ transplantation is to be ascribed among the successes of medicine in the just closed century.

Vasoplegia is a pathophysiologic state of hypotension in the setting of normal or high cardiac output and low systemic vascular resistance despite euvolemia and high-dose vasoconstrictors. Vasoplegia in heart, lung, or liver transplantation is of particular interest because it is common (approximately 29%, 28%, and 11%, respectively), is associated with adverse outcomes, and because the agents used to treat vasoplegia can affect immunosuppressive and other drug metabolism. This narrative review discusses the pathophysiology, risk factors, and treatment of vasoplegia in patients undergoing heart, lung, and liver transplantation.

Frostbite injury refers to cold tissue injury which typically affects the peripheral areas of the body, and is associated with limb loss and high rates of morbidity. Historically, treatment options have been limited to supportive care, leading to suboptimal outcomes for affected patients. The pathophysiology of frostbite injury has been understood in recent years to share similarity with that of cold ischemia-reperfusion injury as seen in solid organ transplantation, of which mitochondria play an important contributing role.

Transplantation-associated thrombotic microangiopathy (TMA) is a severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with high mortality. As calcineurin inhibitors (CNIs) reportedly contribute to TMA via drug-induced endothelial injury, treatment of TMA often involves CNI discontinuation or dose reduction. However, renal-limited TMA, defined as biopsy-proven renal TMA without the classical triad (hemolytic anemia, thrombocytopenia, and organ damage), has rarely been reported after allo-HSCT, and its optimal management remains unknown.

has been widely used in traditional Chinese medicine for several thousands of years. This plant is known for tonifying kidney Yang, strengthening muscles and bones, and dispelling wind and dampness. It is worth noting that icaritin, a prenylated flavonoid isolated from , has received increasing attention in recent years due to its wide range of pharmacological activities.

There is substantial variation in access to transplantation across the United States that is not entirely explained by the availability of donor organs. Barriers to transplantation and variation in care among patients with end-stage organ disease exist prior to patients' placement on a transplant waiting list as well as following waitlist placement. However, there are currently no national data available to examine rates and variations in key care processes related to pre-listing, including transplant referral, evaluation, or candidate selection.
