BACKGROUND Chronic hemodialysis patients frequently require vascular access through central venous catheters (CVCs). The most significant complication of these catheters is infection. This risk can be lowered by the use of an antibiotic-Heparin lock. This study focuses on hemodialysis patients using Tunneled-cuffed catheters (TCC), to assess the rate of catheter-related infections (CRI) in cath...

OBJECTIVE To compare the occurrence of hypoglycemia during hemodialysis in chronic kidney disease diabetic patients who present different levels of pre-dialysis glycemia both when using dialysis solutions with and without glucose. SUBJECTS AND METHODS Twenty type 2 diabetic patients in maintenance hemodialysis were submitted to three dialysis sessions (at a 7-day interval each) with dialysis ...

BACKGROUND AND OBJECTIVES Concentrated heparin solutions are instilled into the catheter lumens after each hemodialysis session to prevent catheter thrombosis. The heparin lock concentration at many centers has been decreased recently to reduce the risk of systemic bleeding and contain costs. However, the effect of this change on catheter patency is unknown. We compared catheter patency between...

The article deals with various ways of memristor modeling and simulation in the MATLAB&Simulink environment. Recently used and published mathematical memristor model serves as a base, regarding all known features of its behavior. Three different approaches in the MATLAB&Simulink system are used for the differential and other equations formulation. The first one employs the standard system core ...

More than 1.2 million people worldwide require regular hemodialysis therapy to treat end stage renal failure. Current hemodialysis systems are too expensive to support at-home hemodialysis where more frequent and longer duration treatment can lead to better patient outcomes. The key cost driver for hemodialysers is the cost of the hemodialysis membrane. Microchannel hemodialysers are smaller pr...

BACKGROUND The cost of dialysis in low and middle-Income countries has not been systematically reviewed. The objective of this article is to systematically review peer-reviewed articles on the cost of dialysis across low and middle-income countries. METHODS PubMed and Embase databases were searched for the year 1998 to March 2013, and additional studies were added from Google Scholar search. ...

BACKGROUND AND OBJECTIVES Cool dialysate may ameliorate intradialytic hypotension (IDH). It is not known whether it is sufficient to prevent an increase in core temperature (CT) during hemodialysis (HD) or whether a mild decline in CT would yield superior results. The aim of this study was to compare both approaches with regard to IDH. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Fourteen HD...

This retrospective study was performed to determine the ranges of the sodium gradient (SG) between the dialysate sodium concentration (DNa) and serum sodium concentration (SNa) in hemodialysis (HD) patients and to examine the relationships between HD parameters over a 1 year period. Fifty-five clinically stable HD patients, who had been on HD >2 years were enrolled. Monthly HD [ultrafiltration ...

During an outbreak of methanol poisonings in the Czech Republic in 2012, we were able to study methanol and formate elimination half-lives during intermittent hemodialysis (IHD) and continuous veno-venous hemodialysis/hemodiafiltration (CVVHD/HDF) and the relative impact of dialysate and blood flow rates on elimination. Data were obtained from 11 IHD and 13 CVVHD/HDF patients. Serum methanol an...

A fter three decades during which the treatment of end-stage renal disease (esRd) has altered very little, things are at last starting to change. And one of the companies driving that change is Alcester, uK-based Quanta Fluid Solutions Ltd., a venture-backed concern that is hoping to make its market debut later this year. Also known as chronic renal failure, esRd occurs when kidney function is ...
