Many centers are reluctant to use older donors (>44 years) for adult right-lobe living donor liver transplantation (RLDLT) due to concerns about possible increased morbidity in donors and poorer outcomes in recipients. Since 2000, 130 adult RLDLTs have been performed at our institution. Recipients were divided into those who received a right lobe graft from a donor ≤age 44 (n = 89, 68%; median age 30) and those who received a liver graft from a donor age >44 (n = 41, 32%; mean age 52). The two donor and recipient populations had similar demographic and operative profiles. With a median follow-up of 29 months, the severity and number of complications in older donors were similar to those in younger donors. No living donor died. Older donor allografts had initial allograft dysfunction compared to younger donors. Complication rates were similar among recipients in both groups but there was a higher bile duct stricture rate with older donor grafts (27% vs. 12%; p = 0.04). One-year recipient graft survival was 86% for older donors and 85% for younger donors (p = 0.95). Early experience with the use of selected older adults (>44 years) for RLDLT is encouraging, but may be associated with a higher rate of biliary complications in the recipient. 相似文献

The mechanism of erythropoietin (Ep) production after acute haemorrhage has been thought to be due to a reduction in blood volume and tissue perfusion leading to tissue hypoxia. In the present study we have evaluated the effect of acute haemorrhage in the rat on the acid-base status, the red cell affinity for oxygen in vivo, and Ep production. Within a few hours after acute blood loss there was a respiratory alkalosis with an increase in blood pH, a decrease in pCO2 and an increase in the red cell affinity of Hb for oxygen in vivo that was temporally related to an increase in Ep production. Within 24 h after the acute haemorrhage, the blood pH AND PCO2, red cell affinity for oxygen in vivo, and Ep level returned towards normal. The decrease in in vivo red cell affinity for oxygen was associated with an increase in red cell 2,3-DPG levels and a decrease in Ep production. 相似文献

HCV infection is a major world health problem, leading to both end‐stage liver disease and primary liver cancer. Great efforts have been made in developing new therapies for HCV infection; however, combination therapy with pegylated IFN‐α and ribavirin (pegIFN‐RBV) remains the first choice of treatment for chronic HCV infection in most countries. The treatment response to pegIFN‐RBV remains relatively low. Understanding the molecular mechanisms of persistent HCV infection and pegIFN‐RBV resistance will suggest ways of improving the current standard of care and offers new antiviral therapies for both HCV and other viral infections. Recent data suggest that increased expression of hepatic IFN‐stimulated genes (ISGs) before treatment is associated with treatment nonresponse in patients chronically infected with HCV. Although ISGs are generally antiviral in nature, in the case of HCV, the virus may exploit some of them to its benefit. This is not unique to HCV: Blockade of type I IFN signaling has been shown to control persistent LCMV infection. Thus, in certain viral infections, preactivation or overactivation of type I IFN signaling may contribute to viral persistence. In this review, we briefly summarize the findings from high‐throughput gene expression profiling from patients chronically infected with HCV, then focus on a novel ubiquitin‐like signaling pathway (ISG15/USP18) and its potential role in HCV persistence. Finally, the role of activation of endogenous type I IFN signaling in persistent HCV infection will be discussed in the context of recent studies indicating that blocking IFN signaling controls persistent LCMV infection.

Background
The cost implications of laparoscopic distal pancreatectomy (LDP) and a detailed breakdown of hospital expenditures has not been presented in the literature to date. This study aimed to compare hospital costs and short-term clinical outcomes between LDP and open distal pancreatectomy (ODP). 相似文献7.

The unique pathophysiology of patients with end-stage liver disease has important implications for their critical care treatment, particularly in the postoperative state. To gauge hemodynamic parameters and responses, each patient must be carefully evaluated for their place in the clinical spectrum of cirrhosis and portal hypertension. Although the data are limited, the biology of the consequences of liver disease is emphasized by novel treatments of hepatorenal syndrome, portopulmonary hypertension, and hepatopulmonary syndrome. These issues become more relevant with increased adult-to-adult living donor liver transplantation, in which technical considerations may further complicate the general treatment of the postoperative transplant patient. 相似文献
