Consensus document from the Spanish Society for Liver Transplantation: enhanced recovery after liver transplantation.

The goal of the Spanish Society for Liver Transplantation (La Sociedad Española de Trasplante Hepático) is to promote and create consensus documents about current topics in liver transplantation with a multidisciplinary approach. To this end, in November 2022, the 10th Consensus Document Meeting was held, with the participation of experts from the 26 authorized Spanish liver transplantation programs. This edition discusses Enhanced Recovery After Liver Transplantation, dividing needed actions into three periods: preoperative, intraoperative and postoperative.

Liver transplantation using uncontrolled non-heart-beating donors under normothermic extracorporeal membrane oxygenation.

Because of the organ shortage, non-heart-beating donors have been proposed as a possible source of grafts for orthotopic liver transplantation (OLT). Despite the widespread use of controlled non-heart-beating donors, there are only a few published studies reporting the outcomes with uncontrolled non-heart-beating donors (UNHBDs). A prospective case-control study on adult patients undergoing OLT was designed.

Antimicrobial resistance and phage and molecular typing of Salmonella strains isolated from food for human consumption in Spain.

The aims of this study were to ascertain the population structure and antimicrobial susceptibility of Salmonella enterica serovars isolated in 2002 from food in 16 Spanish regions. Serovars were characterized by serotyping, phage typing, antimicrobial susceptibility, and pulsed-field gel electrophoresis (PFGE) typing, and 264 nonrelated strains were selected for further analysis. The main sources were eggs and their derivatives (21.

Relationship of pulsed-field profiles with key phage types of Salmonella enterica serotype Enteritidis in Europe: results of an international multi-centre study.

Salmonella is one of the most common causes of foodborne infection in Europe with Salmonella enterica serovar Enteritidis (S. Enteritidis) being the most commonly identified serovar. The predominant phage type for S.

Blind comparison of traditional serotyping with three multiplex PCRs for the identification of Salmonella serotypes.

Salmonella serotypes are defined on the basis of somatic (O) antigens which define the serogroup and flagellar (H) factor antigens, both of which are present in the cell wall of Salmonella. Most Salmonella organisms alternatively express phase-1 or phase-2 flagellar antigens encoded by fliC and fljB genes, respectively. Our group previously published two multiplex PCRs for distinguishing the most common first- and second-phase antigens.

Epidemiological tracing of Salmonella enterica serotype Abortusovis from Spanish ovine flocks by PFGE fingerprinting.

Salmonella enterica serotype Abortusovis, an ovine host-specific serotype, rare in most countries, is responsible for epidemic abortion episodes in Spain. With the aim of surveillance and detection of the spread of specific clones, 55 Abortusovis isolates collected during 1996-2001 from flocks in 11 provinces, were studied using XbaI-PFGE. Despite the fact that the strains were geographically and spatially related, PFGE demonstrated an epidemiologically acceptable discriminating power, identifying 20 clones (similarity, 52-96%).

Antimicrobial resistance in non-typhoidal Salmonella from human sources, Spain, 2001-2003.

Objectives: To determine the current state of antimicrobial resistance among non-typhoidal Salmonella strains isolated from humans in Spain.

Methods: All strains of Salmonella from human sources received in the reference laboratory from 2001 to 2003 were serotyped and phage types were determined in the most common serovars. A systematic sampling procedure was carried out in order to obtain a random sample for susceptibility testing.

Distribution of molecular subtypes within Salmonella enterica serotype Enteritidis phage type 4 and S. Typhimurium definitive phage type 104 in nine European countries, 2000-2004: results of an international multi-centre study.

This study investigates the distribution of pulsed-field gel electrophoresis (PFGE) profiles within Salmonella enterica serotype Enteritidis phage type (PT) 4 and S. Typhimurium definitive phage type (DT) 104, from cases of human infection in nine European countries from 2000 to 2004. Isolates were subtyped using standardized methods and gel images submitted by each participating country to the coordinating centre (Health Protection Agency Centre for Infections, London, UK), where they were entered into a central database, developed within BioNumerics software, and designated using an agreed nomenclature.

Hepatic vein reconstruction in living donor liver transplantation.

Introduction: Living donor liver transplantation has emerged as a response to the cadaveric graft shortage, especially for adult recipients. Both right and left liver grafts are widely used, although some technical problems remain unresolved. Herein we describe our technique for reconstruction of the venous outflow in living donor liver transplantation.

Short- and long-term outcomes after living donor liver transplantation.

Introduction: Living donor liver transplantation was first described as a way to alleviate the organ shortage. Extensive studies of both the prospective donor and the recipient are necessary to ensure successful outcome. In this paper we describe our results in 28 living donor liver transplantations from the perspective of the donor and the recipient.

Does preoperative fine needle aspiration-biopsy produce tumor recurrence in patients following liver transplantation for hepatocellular carcinoma?

Introduction: Liver transplantation (OLT) has been advocated for patients with carcinoma hepatocellular (HCC). A preoperative biopsy (fine needle aspiration biopsy) [FNA] facilitates preoperative diagnosis of adverse pathological factors: vascular invasion or histologicalic differentiation. But a biopsy may cause abdominal dissemination and be related to a higher incidence of recurrence.

A foodborne outbreak of Salmonella infection due to overproduction of egg-containing foods for a festival.

A large outbreak of gastroenteritis occurred in Catalonia in June 2002 with 1435 cases and 117 hospitalizations. Consumption of a hard pastry with vanilla cream was strongly associated with illness. Stool samples from cases and food-handlers were analysed.

Salmonella Derby clonal spread from pork.

The genetic diversity of the Derby serotype of Salmonella enterica in Spain was examined by pulsed-field gel electrophoresis (PFGE). Out of 24 identified PFGE profiles, a major clone was detected in 19% of strains from humans, 52% from food, and 62% from swine. This clone (clone 1) was isolated from pork products, suggesting swine as its source.

Molecular characterization of a new serovar of Salmonella bongori 13,22:z39:- isolated from a lizard.

Three Salmonella strains isolated from a lizard (Gallotia simoni) in the "Isla del Hierro" (Canary Islands, Spain) were serotyped as Salmonella bongori serotype 13,22:z39:-, which has not been described in the Kauffmann-White scheme of Salmonella serovars. In order to shed light on the assignment of those strains to the S. bongori species, several genes were amplified and/or sequenced.

[Serotype and phage type distribution of human Salmonella strains isolated in Spain, 1997-2001].

Introduction: Salmonellosis is one of the most frequent causes of gastroenteritis in Spain. Serotyping is the gold standard epidemiological marker for subdividing Salmonella spp. strains.

Mechanism of resistance to several antimicrobial agents in Salmonella Clinical isolates causing traveler's diarrhea.

The evolution of antimicrobial resistance in Salmonella isolates causing traveler's diarrhea (TD) and their mechanisms of resistance to several antimicrobial agents were analyzed. From 1995 to 2002, a total of 62 Salmonella strains were isolated from stools of patients with TD. The antimicrobial susceptibility to 12 antibiotics was determined, and the molecular mechanisms of resistance to several of them were detected as well.

Phage types and genotypes of shiga toxin-producing Escherichia coli O157:H7 isolates from humans and animals in spain: identification and characterization of two predominating phage types (PT2 and PT8).

Phage typing and DNA macrorestriction fragment analysis by pulsed-field electrophoresis (PFGE) were used for the epidemiological subtyping of a collection of Shiga toxin-producing Escherichia coli (STEC) O157:H7 strains isolated in Spain between 1980 and 1999. Phage typing distinguished a total of 18 phage types among 171 strains isolated from different sources (67 humans, 82 bovines, 12 ovines, and 10 beef products). However, five phage types, phage type 2 (PT2; 42 strains), PT8 (33 strains), PT14 (14 strains), PT21/28 (11 strains), and PT54 (16 strains), accounted for 68% of the study isolates.

Multiplex PCR for distinguishing the most common phase-1 flagellar antigens of Salmonella spp.

Most Salmonella serotypes alternatively express either phase-1 or phase-2 flagellar antigens, encoded by the fliC and fljB genes, respectively. Flagellar phase reversal for the identification of both flagellar antigens is not necessary at the genetic level. Variable internal regions of the fliC genes encoding the H:i, H:r, H:l,v, H:e,h, H:z(10), H:b, and H:d antigens have been sequenced; and the specific sites for each antigen in selected Salmonella serotypes have been determined.

Serotypes and virulence genes of bovine Shigatoxigenic Escherichia coli (STEC) isolated from a feedlot in Argentina.

Grazing-fed cattle were previously demonstrated to be reservoir of non-O157 Shigatoxigenic Escherichia coli (STEC) serotypes in Argentina. The acid-resistance of some STEC strains makes it reasonable to assume the presence in feedlot of particular STEC serotypes. Fifty-nine animals were sampled every 2 weeks during 6 months by rectal swabs.

Fecal shedding of Escherichia coli O157, Salmonella, and Campylobacter in Swiss cattle at slaughter.

Fecal samples from 2,930 slaughtered healthy cattle were examined with the following goals: (i) to monitor the shedding of Escherichia coli O157, Salmonella, and Campylobacter in cattle; and (ii) to further characterize the isolated strains. The percentage of the 2,930 samples that tested positive for E. coli O157 by PCR was 1.

Serotypes, phage types and virulence genes of shiga-producing Escherichia coli isolated from sheep in Spain.

Problem Addressed: Shiga toxin-producing Escherichia coli (STEC), have emerged as food poisoning pathogens which can cause severe diseases in humans.

Objective: The aim of this study was to determinate the serotypes and virulence genes of STEC strains isolated from sheep in Spain, with the purpose of determining whether sheep represent a potential source of STEC pathogenic for humans.

Methods And Approach: Faecal swabs obtained from 697 healthy lambs on 35 flocks in Spain during the years 2000 and 2001 were examined for STEC using phenotypic (Vero cells) and genotypic (PCR) methods.

Verotoxin-producing Escherichia coli in Spain: prevalence, serotypes, and virulence genes of O157:H7 and non-O157 VTEC in ruminants, raw beef products, and humans.

In Spain, as in many other countries, verotoxin-producing Escherichia coli (VTEC) strains have been frequently isolated from cattle, sheep, and foods. VTEC strains have caused seven outbreaks in Spain (six caused by E. coli O157:H7 and one by E.

Use of AFLP, plasmid typing and phenotyping in a comparative study to assess genetic diversity of Shigella flexneri strains.

Shigella flexneri infections are one of the main causes of acute diarrhoea in Cuba. Twenty strains isolated from sporadic cases in nine different Cuban provinces were characterized. Serotyping, antibiotic-resistance typing, plasmid-typing and AFLP-typing were used to determine their suitability for use in epidemiological studies of S.
