Circulating 20S proteasome for assessing protein energy wasting syndrome in hemodialysis patients.

Protein energy wasting (PEW) including muscle atrophy is a common complication in chronic hemodialysis patients. The ubiquitin proteasome system (UPS) is the main proteolytic system causing muscle atrophy in chronic kidney disease and proteasome 20S is the catalytic component of the UPS. Circulating proteasome 20S (c20S proteasome) is present in the blood and its level is related to disease severity and prognosis in several disorders.

Method validation of a set of 12 GEM® Premier™ 4000 blood gas analyzers for point-of-care testing in a university teaching hospital.

Background: Blood gas analyzers are o0.ften integrated into point-of-care testing provisions. International standards (ISO 22870 and 15189) as adapted to French COFRAC regulations make accreditation of point-ofta-care testintag obligatory.

Predictors of Autogenous Arteriovenous Hemodialysis Access Thrombosis after Renal Transplantation.

Background: The fate of autogenous arteriovenous fistula (aAVF) after renal transplantation (RT) remains variable. The aim of this study was to determine the predictors for their thrombosis after RT.

Methods: We conducted a monocentric retrospective review of prospective clinical records of 145 patients with a functional aAVF who had an RT between January 2004 and December 2009 in the University Hospital of Clermont-Ferrand.

Fermentable carbohydrate supplementation alters nitrogen excretion in chronic renal failure.

Background: Considerable attention has been given to the impact of nutrition on kidney disease. Most dietary attempts to treat chronic renal failure (CRF) and to decrease uremia use a protein restriction. An alternative dietetic approach based on fermentable carbohydrate (FC) supplementation of the diet could lead to the same urea-lowering effect by increasing urea nitrogen (N) excretion in stool, with a concomitant decrease of the total N quantity excreted in urine.
