Ventricular assist devices (VAD) have benefitted patients with end-stage heart failure as a bridge to heart transplantation (HTx). We present our experience with HTx after an extracorporeal membrane oxygenation (ECMO) hybrid with various ventricular assist devices (VAD). From May 1996 to December 2003, mechanical circulatory support with a Biopump VAD was performed in eight patients, HeartMate left VAD in eight patients, and Thoratec VAD in eight patients. ⋯ Half of the 24 patients were implanted with VAD to await a suitable donor for HTx. We observed that half of the patients supported by ECMO hybrid with various VAD awaited a suitable donor for HTx. In our experience, we recommend the application of ECMO for short-term support within 1 week and the Biopump VAD, Thoractec VAD, or HeartMate VAD for medium-term or long-term support as a bridge to HTx.

MELD score as a prognostic model for listing acute liver failure patients for liver transplantation.
The King's College Hospital (KCH) criteria are widely used for listing patients with acute liver failure (ALF) for liver transplantation (LT). Recent reports have suggested that the Model for End-Stage Liver Disease (MELD) score may be useful in assessing prognosis in ALF (nonparacetamol). This study compares prognostic accuracy of the two systems in patients with paracetamol (POD)-induced ALF treated in this unit. ⋯ MELD has higher sensitivity and negative predictive value for POD-induced ALF than the KCH criteria. However, the high false-positive rate associated with MELD limits its clinical utility. The high negative predictive value of MELD score may allow it to be used in conjunction with KCH criteria to avoid unneeded LT in patients who will likely recover spontaneously.

We sought to evaluate the effects of ulinastatin on postoperative systemic inflammatory responses of recipients of rat small bowel transplantations (SBT). ⋯ Ulinastatin attenuated the postoperative systemic inflammatory response of rat recipients of SBT.

Early diagnosis of invasive pulmonary aspergillosis (IPA) is important as prompt treatment with antifungal drugs may increase patient survival. Our study investigated the efficiency of routine testing of the Aspergillus galactomannan antigen (AGA) test in combination with chest CT scans for IPA diagnosis. ⋯ The combination of AGA detection and early chest CT scans might be considered useful tools to detect minimal changes of IPA. Based on these findings, aggressive antifungal therapy should be initiated.

Case Reports
Liver transplantation of a child with child a cirrhosis and severe hepatopulmonary syndrome.
Hepatopulmonary syndrome (HPS) is a clinical state defined by a chronic hepatic disorder, intrapulmonary vascular dilatation, and altered gas exchange resulting in hypoxemia. Cirrhosis of the liver is the most common condition associated with HPS. ⋯ The findings of HPS resolved immediately after OLT. His status is within normal limits at 6 months after liver transplantation.
