Background
Patients with chronic kidney disease (CKD) have accelerated cardiovascular and cognitive aging when compared to the non-CKD population. This cognitive decline contributes to excessive rates of physical and functional decline, reduced quality of life, and mortality in the CKD population. Mediterranean diets, a plant-forward diet, have bee...
Objective:
Hemodialysis patients face one of the most difficult diets among clinical patient populations. Furthermore, dialysis dietary adherence is generally reported as low with providers generally lacking the time and resources to implement effective behavior change. The purpose of this study was to elucidate measures of patient and provider en...
Background
Hyperphosphatemia is common in patients on peritoneal dialysis (PD). Restricting dietary phosphorus often leads to a decrease in protein intake, which may result in hypoalbuminemia. The high pill burden of phosphate binders may also contribute to compromised appetite and dietary intake. Hypoalbuminemia is associated with an increased ris...
The Latinx (Hispanic, preferred non-gender-based term for Latino/Latina) community is the
largest racial and ethnic minority group in the U.S., and they experience a disproportionate burden of
chronic kidney disease (CKD) and a faster progression to kidney failure than non-Latinx Whites (1). Due
to a variety of factors, including discordant care, L...
Patients on chronic hemodialysis are counseled to reduce dietary sodium intake to limit their thirst and consequent interdialytic weight gain (IDWG), chronic volume overload, and hypertension. Low-sodium dietary trials in hemodialysis are sparse and mostly indicate that dietary education and behavioral counseling are ineffective in reducing sodium...
This article describes the impact of a 12-week workplace wellness program on staff (n = 14) of an outpatient hemodialysis center. The program focused on decreasing dietary sodium and increasing habitual physical activity. The average systolic and diastolic blood pressure of participants decreased by 16.9±21.6 mmHg (p < 0.05) and 4.1±14.0 mmHg (p <...
Introduction
Patients with kidney failure undergoing maintenance hemodialysis (HD) therapy are routinely counseled to reduce dietary sodium intake to ameliorate sodium retention, volume overload, and hypertension. However, low‐sodium diet trials in HD are sparse and indicate that dietary education and behavioral counseling are ineffective in reduci...
Introduction
Chronic volume overload is a persistent problem in hemodialysis (HD) patients. The purpose of this study was to investigate the impacts of comprehensive volume reduction protocol on HD patient's hydration status and blood pressure (BP).
Methods
Twenty‐three HD patients (age = 55.7 ± 13.3 years) completed a 6‐month comprehensive volume...
Exercise training appears to have modest or inconsistent benefits in hemodialysis patients. This may be due to the low volume and intensity of exercise often prescribed. To address this, research is needed to evaluate the efficacy of individualized exercise prescriptions as a component of a comprehensive lifestyle intervention strategy that gives p...
Previous studies have demonstrated a positive correlation between dietary sodium intake and blood pressure (BP) in hemodialysis (HD) patients. High BP is linked to increased cardiovascular (CV) mortality, and CV disease contributes to 41% of deaths among HD patients. To reduce these risks, HD patients are often counseled to restrict their dietary s...
Synopsis:
Quantitative imaging of tissue sodium content requires corrections for coil loading. This can be done by introducing external calibration standards
within the scan, or by employing the principle of reciprocity to normalize the signal by the voltage required to obtain a signal maximum. A direct
comparison of these two quantification method...
Background: Recent evidence indicates that dietary sodium intake results in the non-osmotic accumulation of sodium in tissue (skin and skeletal muscle) and that this may impact blood pressure (BP). HD patients are often counseled to reduce their sodium intake to <2 grams/day to prevent chronic volume overload and poor outcomes. However, compliance...
Background: The Actigraph GT3X+ (ACT) is a research standard in measuring steps and physical activity, but does not have the convenience of newer commercial devices. The objective of this study was to determine wear compliance and compare differences in steps counts of the Fitbit Flex (FLX), Fitbit Charge HR (CHR), and Jawbone Up2 (JWB) to the ACT...
Background: There are many commercial fitness trackers that can track steps and time spent in sedentary (S), light (L), and moderate to vigorous (MVPA) activity levels. These devices can be worn on the wrist and have been validated in healthy populations against the Actigraph GT3X+ (ACT). However, there is currently little evidence to show that the...
