Background: Heart rate variability (HRV) represents changes in the time between successive heart beats, and it has been used to assess the autonomic nervous system. Previous studies have reported autonomic dysfunction in diabetic patients undergoing hemodialysis (HD), however, no studies have evaluated the effects of age on changes in HRV in these patients. The aim of this study was to examine the effects of age on changes in HRV in diabetic HD patients. Methods: We enrolled 84 diabetic patients receiving maintenance HD...

Hyperuricemia has been associated with low heart rate variability (HRV), however whether there is an association between uric acid (UA) and HRV changes after hemodialysis (HD) is unknown. The aim of this study was to investigate the role of UA in HRV changes before and after HD in non-diabetic patients. Ninety-six non-diabetic patients under maintenance HD were enrolled. HRV was examined to assess changes before and after HD. A change in HRV (ΔHRV) was calculated as post-HD HRV minus pre-HD HRV. Compared to the patients with a UA level ≦ 7 mg/dL, those with a UA level > 7 mg/dL had lower ∆high frequency (HF)% ( p = 0...

BACKGROUND AND OBJECTIVE: One of the most adverse conditions facing the hemodialysis patient is repetitive hypotension during their dialysis session. Different factors can be used to monitor patient conditions and prevent Intradialytic Hypotension (IDH) during hemodialysis. These factors include blood pressure, blood volume, and electrical Impedance factors. In this paper, pre-IDH and IDH episodes were recognized and classified by using the features of the finger photoplethysmography (PPG) signal...

BACKGROUND: Hemodynamic instability related to renal replacement therapy (HIRRT) may increase the risk of death and limit renal recovery. Studies in end-stage renal disease populations on maintenance hemodialysis suggest that some renal replacement therapy (RRT)-related interventions (e.g., cool dialysate) may reduce the occurrence of HIRRT, but less is known about interventions to prevent HIRRT in critically ill patients receiving RRT for acute kidney injury (AKI). We sought to evaluate the effectiveness of RRT-related interventions for reducing HIRRT in such patients across RRT modalities...

Dietary assessment is absolutely necessary to meet the dietary requirements of hemodialysis (HD) patients. A food record is the most commonly used method; however, it is not routinely performed. The weakness of this method is that it is burdensome for some respondents and requires more time to complete data entry. Meanwhile, the brief food frequency questionnaire (BFFQ) is a quicker and simpler method to assess individual dietary intake. We aimed to compare the BFFQ and food records as assessment methods of energy and protein intake for HD patient in Dr...

Anemia is common in patients on hemodialysis (HD). Adequate iron stores are essential for achieving the best hemoglobin level through maximum benefit from erythropoiesis-stimulating agents (ESA). Decreased iron stores or decreased availability of iron are the most common reasons for resistance to the effect of these agents. Our objective was to categorize a group of Iraqi HD patients according to absolute or functional iron deficiency anemia (IDA); this study was conducted in the HD unit of the Baghdad Teaching Hospital from October 2012 to January 2013...

Long-term elevated blood sugar levels result in tissue matrix compositional changes in patients with diabetes mellitus type 2 (T2DM). We hypothesized that hemodialysis patients with T2DM might accumulate more tissue sodium than control hemodialysis patients. To test this,23 Na magnetic resonance imaging (23 Na MRI) was used to estimate sodium in skin and muscle tissue in hemodialysis patients with or without T2DM. Muscle fat content was estimated by1 H MRI and tissue sodium content by23 Na MRI pre- and post-hemodialysis in ten hemodialysis patients with T2DM and in 30 matched control hemodialysis patients...

BACKGROUND/AIMS: Residual kidney function (RKF) is a pivotal predictor of better clinical outcomes in maintenance hemodialysis (MHD) patients. So far there has been no attempt to use bioimpedance analysis (BIA) measurements to calculate residual glomerular filtration rate (GFR) in dialysis population. We hypothesized that performing of multi-frequency BIA at the beginning and end of hemodialysis session can enable us to predict the measured residual GFR in MHD patients. Thus our aim was to develop and validate a new RKF prediction equation using multi-frequency BIA in MHD patients...

In recent years, the population of chronic dialysis has grown in number but also in age and frequency of co-morbidies such as cardiac diseases, vascular pathologies, diabetes, etc. The majority of patients on chronic hemodialysis are over 70 years and, given the high number of comorbidities, they often exhibit poor tolerance to dialysis treatments. A non-tolerated dialytic treatment can have side-effects that would require an intensification of the dialysis sessions and many hospitalizations. Consequently, the problematic dialysis treatments, as well as harmful for the patient, become economically more detrimental than other treatments apparently more expensive but more tolerated ones In the current days we have, thanks to the huge developments in dialysis technology, powerful weapons to ensure effective and scarcely symptomatic dialysis treatments to the majority of the HD patients...

End-stage renal disease (ESRD) patients present high levels of phosphorus and calcium products in serum, which contribute to the development of vascular calcification and cardiovascular disease, and to low iron stores and carnitine deficiency. For these reasons, ESRD patients are generally supplemented with different medicines. Some of the most common treatments include the use of Carnicor, Venofer, and Sevelamer drugs. Carnicor is used as a source of L-carnitine, acting as antioxidant and neuroprotector. Venofer is used to reduce the deficit of iron...

We fabricate a wearable blood leakage sensor on a cotton textile by combining two newly developed techniques. First, we employ a screen-offset printing technique that avoids blurring, short circuiting between adjacent conductive patterns, and electrode fracturing to form an interdigitated electrode structure for the sensor on a textile. Furthermore, we develop a scheme to distinguish blood from other substances by utilizing the specific dielectric dispersion of blood observed in the sub-megahertz frequency range...

BACKGROUND AND OBJECTIVES: Patients undergoing hemodialysis with a frequency other than thrice weekly are not included in current clinical performance metrics for dialysis adequacy. The weekly standard Kt/Vurea incorporates treatment frequency, but there are limited data on its association with clinical outcomes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used multivariable regression to examine the association of dialysis standard Kt/Vurea with BP and metabolic control (serum potassium, calcium, bicarbonate, and phosphorus) in patients incidental to dialysis treated with home (n=2373) or in-center hemodialysis (n=109,273)...
