Plasma Metabolite Profiles Between In-Center Daytime Extended-Hours and Conventional Hemodialysis.

Background: Protein-energy wasting, characterized by disordered body protein catabolism resulting from metabolic and nutritional derangements, is associated with adverse clinical outcomes in patients undergoing hemodialysis. Extended-hours hemodialysis (≥6 h per treatment session) offers both enhanced removal of uremic solutes and better fluid management, generally allowing more liberalized dietary protein and calorie intake. This study aimed to evaluate the difference in plasma metabolite profiles among patients receiving in-center daytime extended-hours hemodialysis and those receiving conventional hemodialysis.

Association of calciprotein particles with serum phosphorus among patients undergoing conventional and extended-hours haemodialysis.

Background And Hypothesis: Extended-hours haemodialysis (HD) is associated with better clinical outcomes than conventional HD. We investigated whether extended-hours HD and conventional HD have varying effects on blood levels of calciprotein particles (CPPs) and phosphorus, which have been identified as major pathogenic molecules for vascular calcification.

Methods: Patients who underwent conventional or extended in-centre daytime HD between January and March 2020 were included.

Extended-Hours Hemodialysis without Dietary Restrictions Increases Body Mass Index and Normalizes Hypertension: A Case Report.

Dialysis technology has made remarkable progress. However, many patients still suffer from malnutrition and hypertension. They cause many complications and significantly impact patients' quality of life and prognosis.

Extended-Hours Hemodialysis without Dietary Restrictions Is Associated with Lower Risk for Developing of Dialysis-Related Amyloidosis.

Dialysis-related amyloidosis (DRA) is characterized by the deposition of amyloid consisting of beta2-microglobulin in the musculoskeletal system, causing carpal tunnel syndrome, destructive spondyloarthropathy, and/or bone cysts. Increased cystic radiolucency of the bones and tendon thickening due to inflammation are common findings in DRA. We have developed a new dialysis method, extended-hours hemodialysis without dietary restrictions for the aim of improving both hypertension and malnutrition.

Impact of old age on the association between in-center extended-hours hemodialysis and mortality in patients on incident hemodialysis.

With the global problem of aging, it has become more difficult to improve the prognosis of older dialysis patients. Extended-hours hemodialysis offers longer treatment time compared to conventional hemodialysis regimen and provides favorable metabolic status, hemodynamic stability, and increased dietary intake. Despite prior studies reporting that in-center extended-hours hemodialysis can reduce the mortality rate, the treatment impact on elderly patients remains unclear.

Repeated femoral vein puncturing for maintenance haemodialysis vascular access.

Background: When access cannot be achieved using a native arteriovenous fistula or a synthetic prosthetic graft, central venous catheters are usually placed. This mode of access is short-lived, prone to infection, stenosis and thrombosis of central veins. To overcome access problems, we developed a new native vascular access ('femoral vein access') and devices.

Useful markers for detecting decreased serum antioxidant activity in hemodialysis patients.

This study evaluates a novel application of a method for measuring serum antioxidant activity, based on the detection of erythrocyte membrane lipid peroxidation in cases of uremia. A human erythrocyte ghost membrane in Tris-HCl was mixed with adenosine 5'-diphosphate and iron chloride (FeCl3; ADP/Fe3+) solution (at a molar ratio of 17:1), and the mixture was incubated under aerobic conditions at 37 degrees C for 2 hours. The concentration of erythrocyte membrane thiobarbituric acid-reactive substances increased proportionally with respect to ADP/Fe3+ concentration, and this increase was inhibited by serum albumin in a dose-dependent manner.
