The study was planned as a case-control study to examine the effects of music on some of the complications experienced by chronic renal failure (CRF) patients during hemodialysis. A total of 60 patients (30 intervention and 30 control) diagnosed with end-stage renal failure undergoing hemodialysis treatment participated in this study. The study was conducted in Manisa Merkez Efendi State Hospital Hemodialysis Unit and Manisa Özel Anemon Hemodialysis between April 2012 and July 2012. The intervention group listened 30 minutes in each session (12 total sessions) Turkish art music at the beginning of the third hour of their hemodialysis sessions. Patient Information Form and visual analog scale to assess pain, nausea, vomiting, and cramps during hemodialysis session were used. For the analysis of data, the number, percentage, chi-square test, and significance test of independent group differences between two averages were conducted. According to the findings of the study, the average of the intervention and control group ages, respectively, was 50.86±11.3 and 55.13±9.68. The primary duration of hemodialysis treatment for both intervention and control groups was "1 year and above" (70.0%). The intervention group's pain and nausea scores were lower than the control group for all 12 sessions. The difference between the intervention and the control group's pain scores was significant (P<0.05). However, in pain scores from the first session to 12th session, continuous decreasing trend was not observed. According to the results, music can be used as an independent nursing practice for reduction of complications for CRF patients receiving hemodialysis treatment. © 2014 International Society for Hemodialysis.

The role of dialysis patients in ensuring their own safety throughout the process of vascular access construction should be far from negligible. Patients can make important contributions to their safety starting in the predialysis stage, via vascular access construction and through the experience of chronic hemodialysis. Currently, patients assume a passive role and their empowerment requires both patients and caregivers to overcome many personal and cultural barriers, thus encouraging safety-related behavior. There are many opportunities for end-stage renal failure patients to be involved in every stage of their disease. In this chapter, we discuss how hemodialysis patients can participate in patient safety, including some of the main opportunities for involvement along the care pathway from the point at which the decision is made that the patient requires vascular access surgery. © 2015 S.

Background/Aims: Several formulas for glomerular filtration rate (GFR) estimation, based on serum creatinine or cystatin C, have been proposed. We assessed the impact of some of these equations on estimated GFR (eGFR) and chronic kidney disease (CKD) prevalence, and on the association with cardiovascular risk factors, in a general population sample characterized by a young mean age. Methods: We studied 1,199 individuals from three Alpine villages enrolled into the MICROS study. eGFR was obtained with the 4- and 6-parameter MDRD study equations, the Virga equation, and with the three CKD-EPI formulas for creatinine, cystatin C, and the combination of creatinine and cystatin C. We assessed the concordance between quantitative eGFR levels, CKD prevalence, and in terms of association with total, LDL, and HDL cholesterol. Results: The highest and lowest eGFR levels corresponded to the cystatin C-based and MDRD-4 equations, respectively. CKD prevalence varied from 1.8% (Virga) to 5.8% (MDRD-4). The CKD-EPI based on creatinine showed the highest agreement with all other equations. Agreement between methods was higher at lower eGFR levels, older age, and in the presence of diabetes and hypertension. Creatinine-based estimates of eGFR were associated with total and low-density lipoprotein but not high-density lipoprotein cholesterol. The opposite was observed for the cystatin C-based GFR. Conclusion: GFR estimation is strongly affected by the chosen equation. Differences are more pronounced in healthy and younger individuals. To identify CKD risk factors, the choice of the equation is of secondary importance to the choice of the biomarker used in the formula. If eGFR is not calibrated to a gold standard GFR in the general population, reports about CKD prevalence should be considered with caution. © 2013 S. Karger AG, Basel.

Magnesium is as an essential metal implicated in numerous physiological functions of human cells. The kidney plays a crucial role in magnesium homeostasis. In advanced chronic kidney disease, serum magnesium levels are increased. Data from experimental and observational studies suggest that low levels of magnesium are associated with several factors, such as insulin resistance, diabetes, oxidative stress, hypertension, atherosclerosis, and inflammation which are implicated in the progression of chronic kidney disease. Moreover, low levels of magnesium have been correlated with cardiovascular disease and all-cause mortality in end-stage renal disease patients. Hypomagnesemia has also been associated with poorer renal allograft and transplant recipients' outcomes. The causality of these relationships has not been completely elucidated. A thorough review of the current literature indicates that low magnesium levels in dialysis patients may reflect a poorer nutritional status and/or are the result of systemic inflammation. Further studies in chronic kidney disease and dialysis patients are needed in order to clarify the causality of these associations. © 2014 International Society for Hemodialysis.

Background and objectives: Obstructive sleep apnea is associated with significantly increased cardiovascular morbidity and mortality. Fluid overload may promote obstructive sleep apnea in patients with ESRD through an overnight fluid shift from the legs to the neck soft tissues. Body fluid shift and severity of obstructive sleep apnea before and after hemodialysis were compared in patients with ESRD. Design, setting, participants, & measurements: Seventeen patients with hemodialysis and moderate to severe obstructive sleep apnea were included. Polysomnographies were performed the night before and after hemodialysis to assess obstructive sleep apnea, and bioimpedance was used to measure fluid overload and leg fluid volume. Results: The mean overnight rostral fluid shift was 1.27±0.41 L prehemodialysis; it correlated positively with fluid overload volume (r=0.39; P=0.02) and was significantly lower posthemodialysis (0.78±0.38 L; P<0.001). There was no significant difference in the mean obstructive apnea-hypopnea index before and after hemodialysis (46.8±22.0 versus 42.1±18.6 per hour; P=0.21), but obstructive apnea-hypopnea index was significantly lower posthemodialysis (−10.1±10.8 per hour) in the group of 12 patients, with a concomitant reduction of fluid overload compared with participants without change in fluid overload (obstructive apnea-hypopnea index +8.2±16.1 per hour; P<0.01). A lower fluid overload after hemodialysis was significantly correlated (r=0.49; P=0.04) with a lower obstructive apnea-hypopnea index. Fluid overload—assessed by bioimpedance—was the best predictor of the change in obstructive apnea-hypopnea index observed after hemodialysis (standardized r=−0.68; P=0.01) in multivariate regression analysis. Conclusions: Fluid overload influences overnight rostral fluid shift and obstructive sleep apnea severity in patients with ESRD undergoing intermittent hemodialysis. Although no benefit of hemodialysis on obstructive sleep apnea severity was observed in the whole group, the change in obstructive apnea-hypopnea index was significantly correlated with the change in fluid overload after hemodialysis. Moreover, the subgroup with lower fluid overload posthemodialysis showed a significantly lower obstructive sleep apnea severity, which provides a strong incentive to further study whether optimizing fluid status in patients with obstructive sleep apnea and ESRD will improve the obstructive apnea-hypopnea index. © 2015 by the American Society of Nephrology.
