BACKGROUND & AIMS: The role of liver transplantation in the treatment of hepatocellular carcinoma in livers without fibrosis/cirrhosis (NC-HCC) is unclear. We aimed to determine selection criteria for liver transplantation in patients with NC-HCC. METHODS: Using the European Liver Transplant Registry, we identified 105 patients who underwent liver transplantation for unresectable NC-HCC. Detailed information about patient, tumor characteristics, and survival was obtained from the transplant centers. Variables associated with survival were identified using univariate and multivariate statistical analyses. RESULTS: Liver transplantation was primary treatment in 62 patients and rescue therapy for intrahepatic recurrences after liver resection in 43. Median number of tumors was 3 (range 1-7) and median tumor size 8cm (range 0.5-30). One- and 5-year overall and tumor-free survival rates were 84% and 49% and 76% and 43%, respectively. Macrovascular invasion (HR 2.55, 95% CI 1.34 to 4.86), lymph node involvement (HR 2.60, 95% CI 1.28 to 5.28), and time interval between liver resection and transplantation <12months (HR 2.12, 95% CI 0.96 to 4.67) were independently associated with survival. Five-year survival in patients without macrovascular invasion or lymph node involvement was 59% (95% CI 47-70%). Tumor size was not associated with survival. CONCLUSIONS: This is the largest reported series of patients transplanted for NC-HCC. Selection of patients without macrovascular invasion or lymph node involvement, or patients 12months after previous liver resection, can result in 5-year survival rates of 59%. In contrast to HCC in cirrhosis, tumor size is not a predictor of post-transplant survival in NC-HCC. [less ▲]

The Belgian experience with donation after cardiac death (DCD) liver transplantation (LT) was retrospectively reviewed, particularly evaluating patient and graft survivals, and biliary complications. From 2003 to 2007, 58 DCD-LT were performed in Belgium. Mean procurement total warm ischemia time was 25 +/- 2 min (mean +/- SEM). Mean cold ischemia time was 451 +/- 18 min. Mean follow-up was 23 +/- 2.2 months. Post-transplant peak aspartate aminotransminases was 2241 +/- 338 UI/l. Patient survivals at 1 month, 1 and 3 years, were 91.3%, 83.3% and 66.9% respectively. Graft survivals at 1 month, 1 and 3 years, were 84.4%, 72.4% and 48.8% respectively. Two patients (3.4%) developed primary nonfunction. Regarding the biliary complications, seven grafts (12%) were lost because of intrahepatic cholangiopathy, and 12 other patients (20.6%) developed bile duct stenoses requiring endoscopic and/or surgical management. The rate of symptomatic ischemic biliary lesions for grafts surviving more than 3 months was 38% (19/50). Although DCD organ donors may be a source of viable liver grafts, results were inferior to those obtained with donation after brain death LT in this series. Prognostic criteria have to be developed to improve results of DCD-LT. [less ▲]

For religious reasons, Jehovah's witnesses refuse transfusion of blood products (red cells, platelets, plasma), but may accept organ transplantation. The authors developed a multidisciplinary protocol for liver transplantation in Jehovah's witnesses. In a 6-year period, nine Jehovah's witness patients were listed for liver transplantation. They received preoperative erythropoietin therapy, with iron and folic acid that allowed significant haematocrit increase. Two patients underwent partial spleen embolization to increase platelet count. Seven patients underwent cadaveric whole liver transplantation, and two right lobe living-related liver transplantation, using continuous circuit cell saving system and high dose aprotinin. No patient received any blood product during the surgical procedure. One patient suffering from deep anaemia after living-related liver transplantation was transfused as required by his family, but died from aspergillus infection. One 6-year-old child was transfused against her parent's will. The authors demonstrated that it is possible to increase haematocrit and platelet levels in cirrhotic patients awaiting liver transplantation. They were able to reduce intraoperative need for blood products, allowing liver transplantation in prepared Jehovah's witness patients. This experience may be beneficial for non-Jehovah's witness liver transplant recipients. [less ▲]

Short- and long-term results of liver transplantation in morbidly obese patients may be impaired compared with the general transplant population. As a consequence, severe obesity has been considered to be a relative contraindication to liver transplantation in many centers. Surgically, liver transplantation in severe obesity may be challenging. Moreover, obesity may lead to an increased rate of early and late medical complications. Herein we have reported successful liver transplantation in a super-obese patient (body mass index, 55.1 kg/m(2)) who had developed terminal acute-on-chronic liver disease. In the first 6 months of follow-up, the patient underwent a severe diet that led to a significant weight loss reduction to a body mass index of 39 kg/m(2). This report of successful liver transplantation in a super-obese patient suggests that severe obesity should not be considered to be an absolute contraindication to liver transplantation. [less ▲]

Although no major arbovirus which mosquitoes are responsible for its transmission has been recorded in Belgium in recent decades, environment and climate change, current and future, could favor the emergence of vector-borne diseases in the country, by inducing changes on Culicidae populations. This study aims to determine the potential importance of agricultural environments, and especially livestock farms, to welcome and favor the proliferation of certain species of mosquito responsible for transmission of arboviruses. A taxonomic inventory was conducted in 2008 (III, VI and X) and 2009 (V and IX) in ten cattle farms, and in 2010 (X) in ten stables located in Belgium. The harvest of mosquitoes is based on larval sampling at the level of 14 biotopes such as water troughs, used tires, abandoned utensils and temporary puddles or not. The morphotaxonomic study of larvae and genitalia has allowed to identify eight species in 18 study stations. These are Anopheles claviger Meigen, 1804 ; A. maculipennis s.l. Meigen, 1818 ; Culiseta annulata Schrank, 1776 ; Cs. morsitans Theobald, 1901 ; Culex modestus Ficalbi, 1889 ; Cx. torrentium Martini, 1925 ; Cx. territans Walker, 1856 and Cx. pipiens s.l. L., 1758. Of the 1843 individuals examined in 2009, Cx. pipiens s.l. represents 79.98% of the total harvest; however, Cx. modestus represents only 0.92%. Used tires form the most favorable habitat for larval development of Culicidae. Therefore, despite the low diversity of mosquito observed within the livestock environments, they represent a significant risk for the reproduction of some potential vectors of arboviruses. In addition, some larval habitats constitute very favorable sites for proliferation of mosquito, causing a real problem of nuisance for animals of farms. [less ▲]

Anionic polymerization of 2-(tert-butylamino)ethyl methacrylate (tBAEMA), which bears an unprotected secondary amine moiety, has been investigated in THF at -78°C. The presence of lithium chloride has been shown to be desirable to afford narrow molecular weight distribution as well as a good agreement between theoretical and observed molecular weight. The living character of the polymerization has also been demonstrated, and the synthesis of block copolymers carried out successfully. They have been analyzed by SEC by adding a mixture of secondary and tertiary amines to the eluent (THF) so as to avoid any polymer adsorption during elution. © 1997 John Wiley [less ▲]

Anionic polymerization of (dimethylamino)ethyl methacrylate (DMAEMA) has been investigated in THF at -78°C. The presence of lithium chloride has been shown to be desirable in order to afford a narrow molecular weight distribution as well as a good agreement between theoretical and observed molecular weight. The living character of the polymerization has been demonstrated. Thus the synthesis of block copolymers, some of them unattainable by GTP, has been carried out successfully. Finally, the anionic polymerization of mixtures of tert-butyl methacrylate (tBMA) and DMAEMA has been considered and their relative reactivity ratio estimated. The easy quaternization of (dimethylamino)ethyl methacrylate affords amphiphilic water-soluble copolymers displaying interesting characteristics as polymeric dispersants and surfactants. [less ▲]
