Effect of Intradialytic Exercise on Physical Performance and Cardiovascular Risk Factors in Patients Receiving Maintenance Hemodialysis: A Pilot and Feasibility Study.

Introduction: Although intradialytic exercise is considered a form of "nonpharmacological medicine" for patients receiving maintenance hemodialysis (MHD), this practice has not been widely implemented in most dialysis centers because of clinical limitations. We, therefore, aimed to design an intradialytic exercise training program to improve the implementation of this practice and determine its impact on physical performance and cardiovascular risk factors in patients receiving MHD.

Methods: A total of 132 MHD patients at 4 outpatient dialysis units were enrolled and assigned randomly into exercise (n = 67) and control groups (n = 65).

Motivators for and Barriers to Exercise Rehabilitation in Hemodialysis Centers: A Multicenter Cross-Sectional Survey.

Objectives: The aim of the study was to explore motivators for and barriers to exercise rehabilitation in hemodialysis patients and the barriers perceived by the hemodialysis center staff.

Design: A cross-sectional study was performed in five hemodialysis centers using patient questionnaires designed for this study to evaluate the motivators for and barriers to exercise rehabilitation. Questionnaires were not yet validated.

Distribution of reference GFR in a development population: a critical factor for the establishment of a GFR estimation equation.

Background And Aim: Our previous work showed that the performance of MDRD equations could be improved by modifying the original MDRD equation. However, during the modification we recognized that reference GFR (rGFR) distribution was not similar between the MDRD study and the Chinese Estimating GFR (eGFR) Investigation Study. This present study was designed to illustrate that the GFR estimating equation might be influenced by the difference of rGFR distribution in the development population.
