Validation of brain extracellular glycerol as an indicator of cellular membrane damage due to free radical activity after traumatic brain injury.

2008

Following severe traumatic brain injury (TBI), increasing oxygen delivery to the brain has been advocated as a useful strategy to reverse mitochondrial dysfunction and improve neurological outcome. However, this might also promote overproduction of free radicals, responsible for lipid peroxidation and hence brain cell damage. Therefore, a method for monitoring this potential adverse effect in humans is desirable. Glycerol, an end product of phospholipid breakdown, easily detectable in the human brain by means of microdialysis, might represent a reliable indicator of free radical-induced cell membrane damage. Brain microdialysates were collected from 24 adult male Sprague-Dawley rats over a …

Comparison of results of combined liver-kidney transplantation vs. isolated liver transplantation

2013

Introduction. Combined liver-kidney transplantation (LKT) is the best therapeutic option for patients with end-stage liver and kidney disease. Objectives. To analyze baseline characteristics and clinical outcome of LKT compared to isolated liver transplantation (LT). Material and methods. The study included 16 LKT performed between 1998 and 2006 and 32 LT matched by age, sex, date and indication for transplantation. Demographic, pretransplant, post-transplant and survival variables were analyzed. Results. As planned by the study design, mean age, distribution by sex and indication for LT were similar between groups. The most common indication for LT was HCV- and/or alcohol-induced cirrhosis…

High-urgency kidney transplantation in the Eurotransplant Kidney Allocation System : success or waste of organs? The Eurotransplant 15-year all-centr…

2016

Item does not contain fulltext BACKGROUND: In the Eurotransplant Kidney Allocation System (ETKAS), transplant candidates can be considered for high-urgency (HU) status in case of life-threatening inability to undergo renal replacement therapy. Data on the outcomes of HU transplantation are sparse and the benefit is controversial. METHODS: We systematically analysed data from 898 ET HU kidney transplant recipients from 61 transplant centres between 1996 and 2010 and investigated the 5-year patient and graft outcomes and differences between relevant subgroups. RESULTS: Kidney recipients with an HU status were younger (median 43 versus 55 years) and spent less time on the waiting list compared…

Impacto pronóstico a largo plazo de la anticoagulación en pacientes en hemodiálisis con fibrilación auricular

2018

Resumen: Introducción y objetivos: La evidencia de la eficacia y seguridad de la anticoagulación oral con dicumarínicos en pacientes en hemodiálisis con fibrilación auricular (FA) es controvertida. El objetivo de nuestro estudio es evaluar las implicaciones a nivel pronóstico a largo plazo de la anticoagulación con dicumarínicos en una cohorte de pacientes con FA no valvular en programa de hemodiálisis debido a insuficiencia renal terminal. Métodos: Estudio observacional retrospectivo con inclusión consecutiva de 74 pacientes en hemodiálisis con FA. El periodo de inclusión fue de enero de 2005 a octubre de 2016. Las variables principales fueron mortalidad por todas las causas, reingresos no…

Valoración de los cambios de los aniones orgánicos que participan en el equilibrio ácido-base al introducir un regimen de biofiltración sin acetato

2011

VALORACIÓN DE LOS CAMBIOS DE LOS ANIONES ORGÁNICOS QUE PARTICIPAN EN EL EQUILIBRIO ÁCIDO-BASE AL INTRODUCIR UN REGIMEN DE BIOFILTRACIÓN SIN ACETATO. La corrección de la situación de acidosis metabólica común a la insuficiencia renal crónica es uno de los objetivos prioritarios del tratamiento de sustitución dialítico. La diálisis es capaz de producir cambios en el perfil metabólico dependientes de la modalidad y del líquido empleados. Realizamos un estudio con 22 pacientes estables en programa de hemodiálisis que se sometieron de forma cruzada a dos modalidades de hemodiafiltracion una con 34 mmol/l de bicarbonato y 3 mmol/l de acetato (HDF) y la otra biofiltración sin acetato (AFB). Según …

dentity Narrative in informal family and non-family caregivers of people on dialysis

2019

Objetivo. Explorar la identidad narrativa de las cuidadoras informales familiares o no, de personas en diálisis. Método. Entrevistas en profundidad a 9 cuidadoras de personas de programas de Hemodiálisis o Diálisis Peritoneal del Hospital General Universitario. Se obtuvo autorización del Comité de Ética y los consentimientos informados de los participantes. El análisis se hizo desde la Teoría Fundamentada. Las narraciones transcritas y codificadas fueron sometidas a reflexión hermenéutica. Resultados. La enfermedad genera un impacto y las cuidadoras asumen el cuidado como pueden. Surge el sentimiento de “cuidado como destino” y como dotación intrínseca de “ser mujer”, percibido como una esp…

Influence of the boundary conditions on heat and mass transfer in spacer-filled channels

2017

The purpose of this study is to discuss some problems which arise in heat or mass transfer in complex channels, with special reference to the spacer-filled channels adopted in membrane processes. Among the issues addressed are the consistent definition of local and mean heat or mass transfer coefficients; the influence of the wall boundary conditions; the influence of one-side versus two-side heat/mass transfer. Most of the results discussed were obtained by finite volume CFD simulations concerning heat transfer in Membrane Distillation or mass transfer in Electrodialysis and Reverse Electrodialysis, but many of the conclusions apply also to different processes involving geometrically compl…

Design, construction and operational results of a pilot plant for the treatment and valorization of pickling waste solutions

2021

An innovative hybrid technology for both minimizing the waste production and optimizing the pickling process through the continuous control of pickling baths composition has been proposed by means of a pilot-plant installed at the Tecnozinco Srl, Carini (PA) hot-dip galvanizing plant. The recovery process has been accomplished by coupling a diffusion dialysis (DD), where HCl is recovered, a membrane distillation (MD), where HCl is concentrated, and a reactive precipitation (RP), where metal ions are recovered as iron hydroxide and ammonium/zinc chloride solution, to be used in the fluxing baths of the plant. The pilot plant was commissioned and operated using synthetic HCl solutions first a…
