The impact of hepatitis E infection on hepatic fibrosis in liver transplanted p...

ABSTRACT Hepatitis E Virus (HEV) is an infection known worldwide for its asymptomatic and self-limited course in most cases. Some cases progressing to chronicity have been described in immunosuppressed patients, especially in recipients of solid organ transplants. We evaluated laboratory parameters of HEV infection (HEV RNA, anti-HEV IgM and anti-HEV IgG) through enzyme-linked immunosorbent assay (Elisa), confi...

COVID-19-related hospital cost-outcome analysis: The impact of clinical and dem...

ABSTRACT Introduction: Although patients’ clinical conditions have been shown to be associated with coronavirus disease (COVID-19) severity and outcome, their impact on hospital costs are not known. This economic evaluation of COVID-19 admissions aimed to assess direct and fixed hospital costs and describe their particularities in different clinical and demographic conditions and outcomes in the largest public ...

The liver injury following ischemia and reperfusion is worse in experimental kn...

Abstract Purpose: To evaluate that Connexin (Cx43) plays a role in lesions after hepatic ischemia/reperfusion (IR) injury. Methods: We use Cx43 deficient model (heterozygotes mice) and compared to a wild group. The groups underwent 1 hour ischemia and 24 hours reperfusion. The heterozygote genotype was confirmed by PCR. We analyzed the hepatic enzymes (AST, ALT, GGT) and histology. Results: The mice with Cx43 d...

Mechanisms of the beneficial effect of sevoflurane in liver ischemia/reperfusio...

PURPOSE: To evaluate the underlying mechanisms by which sevoflurane protects the liver against ischemia/reperfusion injury evaluate the mechanism by which sevoflurane exerts this protective effect. METHODS: Twenty-six rats were subjected to partial ischemia/reperfusion injury for 1h: one group received no treatment, one group received sevoflurane, and sham group of animals received laparotomy only. Four hours a...

Healthcare resource utilization and costs of outpatient follow-up after liver t...

CONTEXT AND OBJECTIVE:Data on the costs of outpatient follow-up after liver transplantation are scarce in Brazil. The purpose of the present study was to estimate the direct medical costs of the outpatient follow-up after liver transplantation, from the first outpatient visit after transplantation to five years after transplantation.DESIGN AND SETTING:Cost description study conducted in a university hospital in...

Video assisted resections. Increasing access to minimally invasive liver surgery?

Objective: To evaluate perioperative outcomes, safety and feasibility of video-assisted resection for primary and secondary liver lesions. Methods : From a prospective database, we analyzed the perioperative results (up to 90 days) of 25 consecutive patients undergoing video-assisted resections in the period between June 2007 and June 2013. Results : The mean age was 53.4 years (23-73) and 16 (64%) patients wer...

Cardiohepatic Interactions - from Humoral Theory to Organ Transplantation

Surfactant protein A is decreased in the lung of rats with hepatopulmonary synd...

PURPOSE:To evaluate surfactant protein A levels in an hepatopulmonary syndrome rat model. To date, there have been no studies aimed at evaluating surfactant levels in the setting of cirrhosis or hepatopulmonary syndrome.METHODS:A total of 35 rats were divided into control, sham, and experimental HPS groups. We evaluated surfactant protein A levels in rats and the experimental model designed to induce hepatopulm...

Effects of hyperbaric oxygen therapy as hepatic preconditioning in rats submitt...

PURPOSE:To analyze the role of hyperbaric oxygen therapy as hepatic preconditioning in rats submitted to hepatic ischemia and reperfusion.METHODS:Wistar rats were randomly divided into three groups: SHAM, rats submitted to surgical stress without hepatic ischemia and reperfusion, I/R, rats submitted to total hepatic pedicle ischemia for 30 min, followed by 5 min of reperfusion; HBOI/R, rats submitted to 60 minu...

Superoxid dismutase activity in portal vein endothelium after partial liver res...

PURPOSE: To investigate superoxide dismutase (SOD) activity in the portal vein endothelium and malondialdehyde acid (MDA) production in liver tissue of rats submitted to 70% hepatectomy. METHODS:Twelve rats were distributed in two groups (hepatectomy and sham). Animals were sacrificed on post operative day 1 and portal vein, liver tissue and blood samples were collected. Portal vein SOD production was measured ...
