Preemptive kidney transplant from deceased donors: an advantage in relation to reduced waiting list.
Preemptive living donor kidney transplantation is associated with better allograft and recipient survival. However, it remains unclear whether preemptive transplantation from deceased donors is beneficial too. An increased number of deceased donors has reduced the waiting list in our hospital in the last years allowing preemptive deceased donor kidney transplantation (PDDKT). ⋯ PDDKT is the treatment of choice for ACKD. It is associated with less delayed graft function and similar 2-year graft and patient survivals than kidney transplantation after dialysis. The Charlson index reflected less comorbidity among patients with PDDKT, a finding that must influence long-term outcomes.

We hypothesized that the arterial blood gas oxygen tension/fraction of inspired oxygen ratio (PaO2/FiO2) would prove to be useful as a mortality marker after lung transplantation (LT). The aims of this study were to define the prevalence of various ranges of PaO2/FiO2 during the first 24 hours after LT and to evaluate which measurement using the PaO2/FiO2 best correlates with mortality. ⋯ A value of PaO2/FiO2 >100 mm Hg 24 hours after admission to the ICU is associated with a lower mortality.

To identify outcome predictors and prognostic factors for survival among lung transplant recipients on readmission to the intensive care unit (ICU). ⋯ Readmission to the ICU, which is common among lung transplant recipients, was associated with a high mortality. Sepsis was the main cause of ICU readmission and the most frequent cause of death. APACHE II score, need for mechanical ventilation, number of dysfunctional organs, and delay in ICU readmission were important prognostic factors.

Pentoxifylline (PTX) has been shown to protect the liver against normothermic ischemia-reperfusion (I-R) injury. The aims of this study were to investigate the action of PTX on tumor necrosis factor alpha (TNFalpha) gene transcription following normothermic liver I-R as well as to evaluate the resulting effects on liver function and survival. A segmental normothermic liver ischemia was induced for 90 minutes. ⋯ PTX treatment significantly decreased serum activities of TNFalpha and inhibited liver expression of TNFalpha mRNA. The extent of liver necrosis and serum levels of liver enzymes were significantly decreased by PTX treatment, resulting in a significant increase in 7-day survival compared with nontreated control rats. In conclusion, PTX inhibits liver TNFalpha gene transcription, decreases serum TNFalpha levels, and reduces liver injury following normothermic I-R.

Cerebral dysfunction may be fatal in patients with acute liver failure (ALF); intracranial pressure (ICP) monitoring may be mandatory to direct measures to prevent further cerebral edema. Recently the introduction of dialysis with the molecular adsorbent recirculating system (MARS) has improved the outcomes among patients with ALF. The aim of this study was to evaluate ICP changes after MARS treatment among patients with ALF. ⋯ MARS treatment improved the clinical pictures of these patients increasing the available time to obtain an urgent liver graft.
