Impact of Pulsatile Machine Perfusion on Posttransplant Recovery in Asystole Donation: Organ Optimization and the Future of Renal Transplantation.

Objectives: With the increase in life expectancy and the aging of the population, chronic kidney disease has become increasingly prevalent in our environment. Kidney transplantation remains the gold standard treatment for end-stage renal disease, but the supply of renal grafts has not been able to keep pace with growing demand. Because of this rationale, organ selection criteria have been extended (expanded criteria donation), and alternative donation types, such as donation after circulatory death, have been evaluated.

[Prognostic factors and response predictors in castration resistant prostate cancer.].

Prostate cancer is a health problem in many Countries worldwide. Understanding the essential function of androgens in the prostate physiology led to the development of hormonal blockade as a therapeutic option in advanced disease, with limited response with time and development of resistance. In this stage, where castration resistant prostate cancer (CRPC) is defined, it is associated with poor prognosis because survival varies between 18 and 24 months.

[Immunotherapy in castration resistant prostate cancer.].

We review the role of immunotherapy in castration resistant prostate cancer. Two immunotherapeutic strategies have been applied, isolated or in combination, either with each other or with other agents with demonstrated efficacy in this scenario that would play a role as immunomodulators: vaccines or monoclonal antibodies aimed to block immune response checkpoint inhibitors. Although CRPC presents, a priori, characteristics suggesting that immunotherapy may play a relevant role as a therapeutic strategy, its clinical application has demonstrated a limited and heterogeneous activity, in terms of proportion of responders and response intensity.
