BACKGROUND: Total/ionized calcium ratio has been used as an indirect index of increased plasma citrate concentration during citrate anticoagulation. However, they were obtained without any adjustment of total calcium for albumin. Herein, we investigated whether the albumin-corrected total/ionized calcium ratio performed better than total/ionized calcium ratio. METHODS: 20 critically ill patients were treated with continuous venovenous hemofiltration (CVVH) using citrate anticoagulation...

BACKGROUND: Sequential peritoneal equilibration test (sPET) is based on the consecutive performance of the peritoneal equilibration test (PET, 4-hour, glucose 2.27%) and the mini-PET (1-hour, glucose 3.86%), and the estimation of peritoneal transport parameters with the 2-pore model. It enables the assessment of the functional transport barrier for fluid and small solutes. The objective of this study was to check whether the estimated model parameters can serve as better and earlier indicators of the changes in the peritoneal transport characteristics than directly measured transport indices that depend on several transport processes...

The frequency of hepatitis C virus (HCV) infection remains high in patients with chronic kidney disease (CKD) and plays a detrimental role in mortality in this population. According to the latest survey, the adjusted hazard ratio for HCV-positive versus HCV-negative patients on long-term dialysis was 1.12 (95% CI, 1.05 to 1.20) and 1.10 (95% CI, 0.98 to 1.22) for all-cause and cardiovascular mortality, respectively. An impairment on quality of life has also been documented in HCV-infected patients undergoing regular dialysis...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has been associated with platelet dysfunction, but no markers of platelet dysfunction during ECMO have been identified. METHODS: We investigated the potential uses of beta-thromboglobulin (beta-TG) and platelet factor 4 (PF4) as markers of platelet activation induced by ECMO in vivo. RESULTS: 13 patients who received ECMO for acute respiratory failure were included. Generalized estimating equations were used to examine the associations between days on ECMO and the plasma levels of beta-TG and PF4 and of proinflammatory markers...

Peristaltic pumps rely on constant compression of elastomeric tubing from which particles may be shed, a phenomenon known as spallation. We studied spallated particles on microfluidic filtration devices with photolithographically prepared micron-level pore fields. Filtration of ultra-pure water through these pores was analyzed using either the usual peristaltic pump or a reciprocating pair of syringe pumps. Using syringe pumps, transmembrane pressure (TMP) values during filtration at 2.5 cm3/min revealed steady filtration for over 80 minutes at 2...

INTRODUCTION: Healing of airway anastomoses after preoperative irradiation can be a significant clinical problem. The augmentation of bronchial anastomoses with a fibroblast-seeded human acellular dermis (hAD) was shown to be beneficial, although the underlying mechanism remained unclear. Therefore, in this study we investigated the fate of the fibroblasts transplanted to the scaffold covering the anastomosis. MATERIAL AND METHODS: 32 Fisher rats underwent surgical anastomosis of the left main bronchus...

In 1977 Peter Kramer performed the first CAVH (continuous arteriovenous hemofiltration) treatment in Gottingen, Germany. CAVH soon became a reliable alternative to hemo- or peritoneal dialysis in critically ill patients. The limitations of CAVH spurred new research and the discovery of new treatments such as CVVH and CVVHD (continuous veno-venous hemofiltration and continuous veno-venous hemodialysis). The alliance with industry led to development of new specialized equipment with improved accuracy and performance in delivering continuous renal replacement therapies (CRRTs)...

INTRODUCTION: Hemodialysis treatment requires anticoagulation to prevent thrombosis of the dialyzer. The Hydrolink® (NV series; Toray) has been designed to reduce thrombotic complications by increasing membrane hydrophilic properties. Previous studies have confirmed reduced platelet activation, improved removal of β2-microglobulin and excellent small-solute removal. METHODS: We designed a prospective, multi-centered, randomized clinical study to compare the antithrombogenic effects (platelet count) of NV dialyzers versus conventional treatment...
