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.

We studied the renal transplantation results of living donor compared with cadaveric donor kidney transplantations. ⋯ The benefit of performing living donor kidney transplantations is the possibility of having the donor available even before beginning dialysis treatment.

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.

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.
