Abstract
OBJECTS This study aimed to determine the relationship between magnesium and PTH levels in peritoneal dialysis (PD) and hemodialysis (HD) patients. METHODS This cross-sectional study was performed on HD and PD patients in Kerman, Iran. After recording demographic and clinical data, the pre-dialysis levels of hemoglobin, 25-hydroxy vitamin D, ferritin, creatinine, calcium, phosphorus, albumin, PTH, and magnesium were measured for all patients. The P value of less than 0.05 was considered statistically significant. RESULTS Magnesium levels in PD patients were significantly higher than in HD patients (P < 0.001). The median PTH level in PD patients was significantly lower than in HD patients (P = 0.046). The correlation between PTH and serum magnesium levels was not significant in PD or HD patients. In the regression model, dialysis modality (PD or HD) was the only significant variable in determining serum magnesium levels (P = 0.005). CONCLUSION Magnesium is a neglected ion in peritoneal dialysis and hemodialysis patients. In dialysis centers that use a dialysate with standard magnesium concentration (0.5 mmol/L in HD and 0.75 mmol/L in PD), special attention is necessary to hypomagnesia and its complications because magnesium levels in PD patients were significantly higher than in HD patients. As the correlation between magnesium and PTH levels in both PD and HD patients were not significant, the association of high magnesium levels with low PTH in PD patients should be considered in terms of increasing the potential for adynamic bone disease. It seems that ordering serum magnesium in the routine tests of dialysis patients is necessary.

Abstract
Objective This study aimed at identifying factors that are associated with sleep disorders in Chinese patients on continuous ambulatory peritoneal dialysis (CAPD). Study Design Questionnaire survey. Setting Renal dialysis unit of a tertiary-care hospital. Patients 179 Chinese patients on CAPD. Main Outcome Measures The quantity and quality of sleep were compared between CAPD patients with and without self-reported sleep disorders. Demographic variables, personality traits, behavioral factors, somatic symptoms, and clinical parameters were correlated with the presence of sleep disorders. Results The mean age of the patients was 61 ± 12 years and the male-to-female ratio was 1:1.3. The mean duration of CAPD was 47 ± 42 months. 110 patients (61%) had self-reported sleep disorders. Among patients with self-reported sleep disorders, difficulty falling asleep was the most frequent complaint (74.5%), followed by frequent awakening (68%) and early morning waking (68%). The mean duration of sleep among these patients was 4.6 ± 2.2 hours, versus 7.3 ± 1.4 hours in patients without self-reported sleep disorders. Three personality traits (anxiety, worry, and sadness) and two somatic symptoms (bone pain and arthralgia) were the factors significantly associated with sleep disorders. Patients with sleep disorders also more frequently reported certain symptoms suggestive of sleep apnea. Demographic variables, behavioral factors ( e.g., caffeine or alcohol intake), and clinical parameters ( e.g., adequacy of dialysis, body mass index, hemoglobin, albumin, parathyroid hormone levels) did not differ between patients with and without sleep disorders. Conclusions Sleep disorders are prevalent among Chinese CAPD patients. Personality traits (anxiety, worry, and sadness) and somatic symptoms (bone pain and arthralgia) were the factors significantly associated with sleep disorders in this patient population. Behavioral factors, demographic variables, and clinical parameters did not appear to predict sleep disorders. Further studies evaluating the impact of various psychological factors on sleep disorders among CAPD patients are warranted.

Abstract
Objectives Sleep disorders are common in end-stage renal disease patients. This study examined the relationship between self-reported quality of sleep (QoS) and certain psychosocial domains for patients on peritoneal dialysis (PD). Methods The study subjects included 190 PD patients from 7 urban dialysis clinics in Northern Taiwan, from whom we obtained biochemical parameters and demographic data. QoS, quality of life (QoL), religious/spiritual activity, and depression were assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire, Medical Outcomes Study Short Form (SF-36) for QoL, the Royal Free Questionnaire, and the Beck Depression Inventory, respectively. Results The average PSQI score was 9.1 ± 4.1 and, in total, 85.8% of all patients were poor sleepers (global PSQI ≥ 5). There was no difference in age, gender, and mode or duration of PD between good and poor sleepers. Biochemical data did not differ between the two groups. Widowed patients experienced significantly poorer QoS than patients with other marital status (PSQI scores: 12.3 ± 4.9 vs 8.88 ± 4.0, p = 0.006). The percentage of patients that held a bachelor's degree or above was significantly higher in good sleepers (55.6% vs 29.4%, p = 0.008). The PSQI value correlated negatively with the QoL scale in both physical ( r = –0.295, p < 0.001) and mental domains ( r = –0.410, p < 0.001), and correlated positively with the depression scale ( r = 0.351, p < 0.001). There appeared to be no association between QoS and spiritual/religious activity ( r = –0.097, p = 0.223). Conclusions Psychosocial factors including depression, patients’ perceptions regarding QoL, marital status, and educational background correlated significantly to the subjective QoS for PD patients. When dealing with sleep disorders in PD patients, physicians should pay considerable attention to their psychosocial backgrounds.

Abstract
A newly developed questionnaire was administered to 140 hemodialyzed patients (82 M and 58 F) who have achieved adequate anemia correction according to the best guidelines with the aim: to evaluate the prevalence of clinical/subclinical dyssomnias in these patients; to study the influence of the dialytic shift (morning versus afternoon schedules) on sleep duration and disturbancies; and to evaluate the relationship between clinical sleep disorders and blood pressure values in uremic patients. Results indicated that 85% of uremic patients undergoing hemodialysis complain of clinical insomnia (frequent, persistent and associated with daytime consequences) or subclinical sleep disorders; patients dialyzing in the morning sleep significantly less during the night preceding the treatment, than those dialyzing in the afternoon; older patients complaining of clinical insomnia have a higher risk of failure to achieve target-optimal values in systolic blood pressure.

Abstract
Purpose Poor sleep quality (SQ) is common in hemodialysis (HD) patients. Factors associated with poor SQ are not well understood. The objectives of the present study were to determine the prevalence of poor SQ in HD patients in our region and to examine the association between SQ and health-related quality of life (HRQoL), depression, and certain clinical and laboratory parameters. Methods A total of 233 HD patients at 5 centers in the city center of Konya, Turkey were included in this study. Their demographic data and biochemical parameters were analyzed. All patients were instructed to complete Turkish versions of three questionnaires, namely, a modified post-sleep inventory (PSI), Beck Depression Inventory (BDI) and a Short Form of Medical Outcomes Study (SF-36). Results The mean age of the patients was 52.8±15.3 years and the male to female ratio was 1.33:1. The prevalence of poor sleepers, defined as those having a total sleep score (PSI-4 score) ≥ 4, was 60.9%. Compared with good sleepers, poor sleepers had higher BDI scores and as well as lower PCS and MCS domains of HRQoL. In addition, poor sleepers were older and more likely to be unemployed. There was a significant inverse correlation of PSI-4 score with PCS and MCS, and significant positive correlation of PSI-4 score with BDI and age (p<0.001). The significant independent predictors of PSI-4 score were BDI score, MCS score and employment status. Conclusions Depression, MCS score and employment status were the most important predictors of sleep quality in HD patients.

Abstract
Background Sleep disorders are very frequent in hemodialyzed patients, but the relationship between these disorders and water withdrawal, urea removal and comorbidities has not been sufficiently clarified. Methods The study comprised a group of 88 patients in good nutritional condition, with target hemoglobin concentration, good control of blood pressure and optimal dry weight. After answering a questionnaire (SDQ) based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) patients were assigned to one of 3 groups: those with no disturbances (no. 20), those with subclinical disorders (n. 35) and insomniacs (n. 33). Yearly fluid and urea withdrawal by dialysis and the Charlson Comorbity Index were measured. Results Sleep disorders were observed in 77.27% of the patients. There was no difference in body fluid and urea withdrawal between groups. In the group of patients with no sleeping disturbances, the Charlson Comorbidity Index was significantly lower (p<0.001) than in patients with subclinical disorders or insomnia and emerged as a strongly associated with sleep disturbances. The study also attributes a predictive role to age, dialytic age, dialysis shift, antihypertensive drugs. The data indicate that, in evaluating sleeping disorders in patients on maintenance hemodialysis, comorbidities should be assessed.

Abstract
INTRODUCTION Chronic kidney disease (CKD) patients have more frequent sleep disorders and cardiovascular disease than normals. Since arterial stiffness as a risk factor of atherosclerosis can be evaluated with pulse wave velocity (PWV), we aimed to investigate the prevalance of sleep quality (SQ) and the relationship between SQ and risk factors of atherosclerosis and whether there is a relationship between SQ and PWV (the indicator of arterial stiffness) in predialysis CKD patients. METHODS This cross-sectional study was carried out in CKD patients followed at the Nephrology Department in Konya, Turkey, between November 2014 and March 2015. A total of 484 CKD patients were screened. Of the 484 patients, 285 patients were excluded. The remaining 199 CKD patients without cardiovascular disease at stage 3, 4, and 5 (predialysis) were included in the final study. The SQ of the patients was evaluated by the Pittsburgh Sleep Quality Index (PSQI). PWV was measured by using a single-cuff arteriography device (Mobil-O-Graph PWA, a model pulse wave analysis device; IEM). RESULTS A total of 199 predialysis CKD patients were included in the study, 73 of whom (36.7 %) were 'poor sleepers' (global PSQI >5). Patients with poor SQ were older than those with good SQ (p = 0.077). SQ was worse in female patients compered to male patients (p = 0.001). SQ was worse in obese patients. As laboratory parameters, serum phosphorus, LDL cholesterol, and triglycerides levels correlated positively with SQ (respectively; r = 0.245, p&0.001; r = 0.142, p = 0.049; r = 0.142, p = 0.048). The indicator of arterial stiffness, PWV, was higher in patients with poor SQ (p = 0.033). Hyperphosphatemia and female gender are determined as risk factors for poor SQ in multivariate analysis (p = 0.049, ExpB = 1.477; p = 0.009, ExpB = 0,429, respectively). CONCLUSIONS Our study showed for the first time that there is a relationship between SQ and risk factors of atherosclerosis in predialysis CKD patients.

Abstract
PURPOSE Inflammation and oxidative stress are involved in the process of chronic renal failure (CRF). CRF patients show indication of sleep disturbances, and the melatonin rhythm, which modulates sleep, is abnormal in these patients; however, it is still unclear whether inflammation could be related to the blockage of melatonin production and sleep disturbances in this population. The aim of this study was to characterize and correlate sleep, the melatonin rhythm, and the levels of the inflammatory cytokines tumor necrosis factor (TNF) and interleukin (IL)-6 in patients with CRF and controls. METHODS Sleep was evaluated by the "Sleep Quality Index Pittsburgh" (PSQI) questionnaire, and melatonin and cytokine contents in saliva and blood samples, respectively, were analyzed by ELISA. RESULTS The CRF group scored higher on the global PSQI, which indicates a lower sleep quality and a higher prevalence of sleep disorders, than the control group. The CRF individuals also showed lower melatonin content than the control groups, both during the day and at night, and lacked rhythmicity in melatonin production. The CRF group also showed higher contents of TNF and IL-6 than the control group and a negative correlation between TNF and melatonin content. CONCLUSION These results suggest that the sleep disorders observed in the CRF group were probably related to the low production of melatonin observed in this population. The high level of TNF, as previously demonstrated in other pathologies, is probably involved in this blockage of melatonin production in CRF.

Abstract
AIM AND OBJECTIVES The aim of this study is to examine the relationship between dialysis adequacy and sleep quality in haemodialysis patients. BACKGROUND Sleep problems are common in haemodialysis patients. Dialysis adequacy is one of the factors associated with sleep quality. Studies evaluating the association between dialysis adequacy and sleep quality in haemodialysis patients present different results. DESIGN Descriptive and cross-sectional study. METHODS This study was performed with a total of 119 patients who had applied to dialysis centres for haemodialysis treatment between January and March 2014. The data collection form consists of socio-demographic and medical characteristics as well as laboratory parameters. A modified Post-Sleep Inventory was used to examine sleep quality in the research. RESULTS There were no statistically significant relationship between sleep quality and dialysis adequacy (p > 0·05). When the Post-Sleep Inventory scores were evaluated according to sleep quality, 63·0% of patients had poor sleep quality, and 37·0% had good sleep quality. Sleep quality was worse in unemployed patients (X(2) = 4·852; p = 0·025) and patients who smoked heavily (Z = 2·289; p = 0·022). CONCLUSIONS In this study, there is no statistically significant relationship between dialysis adequacy and sleep quality. However, it was found that the majority of haemodialysis patients had poor sleep quality. RELEVANCE TO CLINICAL PRACTICE Even if the dialysis adequacy of patients is at the recommended level, their sleep qualities may be poor. Therefore, evaluations of the sleep quality of haemodialysis patients during the clinical practice must be taken into consideration.

Abstract
Patients with advanced chronic kidney disease (CKD) have a high burden of physical and psychosocial symptoms, poor outcomes, and high costs of care. Current paradigms of care for this highly vulnerable population are variable, prognostic and assessment tools are limited, and quality of care, particularly regarding conservative and palliative care, is suboptimal. The KDIGO Controversies Conference on Supportive Care in CKD reviewed the current state of knowledge in order to define a roadmap to guide clinical and research activities focused on improving the outcomes of people living with advanced CKD, including those on dialysis. An international group of multidisciplinary experts in CKD, palliative care, methodology, economics, and education identified the key issues related to palliative care in this population. The conference led to a working plan to address outstanding issues in this arena, and this executive summary serves as an output to guide future work, including the development of globally applicable guidelines.

Abstract
Sleep disorders for patients on dialysis are significant causes of a poorer quality of life and increased morbidity and mortality. No study has evaluated patients undergoing automated peritoneal dialysis (APD) to assess their sleep disorders compared to hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). A total of 166 clinically stable patients who had been on dialysis for at least 3 months were randomly selected for the study and divided into HD, CAPD or APD. Socio-demographic, clinical and laboratory parameters and self-administered questionnaires were collected for the investigation of insomnia, restless legs syndrome (RLS), bruxism, rapid eye movement sleep behavior disorder, excessive daytime sleepiness (EDS), obstructive sleep apnea syndrome (OSAS), sleepwalking, sleep hygiene, depression and anxiety. Insomnia was detected in more than 80 % of patients on the three modalities. OSAS was lower for patients on HD (36 %) than on CAPD (65 %) (p < 0.01) or APD (60 %) (p < 0.04). Patients on APD were more likely to have RLS compared to those on HD or CAPD (p < 0.04) (50 vs. 23 vs. 33 %). No differences among the modalities were found in bruxism, EDS, sleepwalking, sleep hygiene, depression or anxiety. ESRD patients undergoing any one of the three dialysis modalities studied had a high prevalence of sleep disorders. Patients on HD had a lower proportion of OSAS than those on CAPD and APD, which is most likely attributed to their lower body mass indices. The possible causes of higher RLS rates in APD patients have not been established.

Abstract
Health-related quality of life (HRQoL) and sleep quality (SQ) were impaired in patients with end-stage renal disease (ESRD). The impairment of both HRQoL and SQ and being in a depressive mood were found to be associated with increased morbidity and mortality in dialysis patients. We aimed to investigate the association between SQ, HRQoL, and depression, and to define independent predictors of SQ and depression in peritoneal dialysis (PD) and hemodialysis (HD) patients. Ninety HD patients (41 females, 49 males with mean age 50 ± 15.7 years) and 64 PD patients (27 females, 37 males with mean age 52.4 ± 15.3 years) receiving renal replacement therapy for at least 3 months were screened for the assessment of SQ, HRQoL, and depression in this cross-sectional study. A modified postsleep inventory, Short Form of Medical Outcomes Study (SF-36) and Beck depression inventory (BDI) were applied to all patients for evaluating SQ, HRQoL, and depression, respectively. HD and PD patients had similar total SQ scores. Physical and mental component scale of HRQoL were found to be significantly higher in HD patients (p < 0.001). PD patients were found to be much more in depressive mood when compared with HD patients (p < 0.001). Independent predictors of depression in patients were mental component scale of HRQoL, gender (being female), and dialysis modality (being PD patient). Physical component scale was also found to be an independent predictor of SQ. This study showed that despite similar SQ scores between two groups, HD patients had better HRQoL and less depression than PD patients.

Abstract
Sleep disorders are common in hemodialysis patients, although causes and consequences remain unclear. We sought to establish prevalence, determinants, and outcomes of sleep disturbances in patients receiving incremental dialysis. One hundred two unselected patients undergoing incremental high-flux hemodialysis or hemodiafiltration underwent limited overnight sleep study. Large subsets underwent echocardiography, interdialytic ambulatory blood pressure monitoring, and brain natriuretic peptide measurements. Patients were followed up to 44 months. Full sleep data were obtained in 91 patients. All had sleep disturbance as evidenced by an apnea-hypopnea index >5/min. We defined major obstructive sleep apnea (MOSA) as an apnea-hypopnea index ≥ 15, together with either significant oxygen desaturation or symptoms of daytime sleepiness. Forty patients met these criteria. Significant independent predictors of MOSA were age <65 years, male gender, has diabetes, and has a brain natriuretic peptide >2500 pg/mL. Mean ambulatory blood pressure and left ventricular mass index were significantly higher in these patients. In a model controlling for body mass index, high C-reactive protein, and the presence of cancer, MOSA was associated with a twofold increased risk of mortality, although this did not reach statistical significance. MOSA was common, and was associated with hypertension and high left ventricular mass index. Whether obstructive sleep apnea contributes to the high mortality remains to be firmly established.

Abstract
Patients with chronic kidney disease including those undergoing haemodialysis have deranged sleep-wake pattern. In large part this is due to an abnormal circadian cycle of melatonin, a hormone secreted by the pineal gland in the evening and induces sleep. Subjects undergoing automated peritoneal dialysis or nocturnal haemodialysis have better sleep profile compared to those on daytime dialysis. Studies have shown that exogenous melatonin improves sleep-wake cycle in daytime haemodialysis patients. However, large randomised controlled trials are needed in order to establish its role in this patient population.

Abstract
We aimed to compare automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) therapy with regard to patients' excessive daytime sleepiness (EDS) and quality of life (QOL). EDS was assessed with the Epworth Sleepiness Scale (ESS) and QOL with the Medical Outcomes Study 36-Item Short Form (SF-36) health survey. We included 59 patients (CAPD/APD, 30/29; male/female, 33/26; age, 45.3±15.8 years; dialysis duration, 42.0±33.6 months). The CAPD and APD groups were similar with respect to factors that affected sleep quality (age, sex, duration of PD), smoking, alcohol intake, socioeconomic status, body mass index, comorbid disease, and various laboratory parameters. Although one patient (3.3%) treated with CAPD and four patients (13.8%) treated with APD experienced EDS, there was no significant differences in ESS scores between the CAPD and APD patients. There was no difference in the SF-36 total and subscale scores when APD patients were compared with CAPD patients. The independent predictors of ESS were the serum albumin level (β= -2.04, P<0.01), total SF-36 score (β= 0.08, P=0.02), social functioning score (β= -2.47, P=0.01), and role-emotional subscale score (β= -1.12, P=0.05). The incidence of EDS was slightly higher in APD patients, but it did not negatively affect daily activities or QOL.

Abstract
Sleep disorders, such as restless legs, periodic limb movements and sleep apnea, and sleep complaints such as insomnia and daytime sleepiness, are very common in end-stage renal disease patients despite treatment with 3-times-a-week conventional hemodialysis. If left untreated, they are likely to impair quality of life and may alter cardiovascular outcomes in this patient population. Home dialysis has the potential to improve sleep disorders by offering more effective dialysis than conventional modalities. Although there has been little direct comparison between the impact of home dialysis and conventional dialysis on sleep disorders, there is evidence that both nocturnal peritoneal dialysis and nocturnal hemodialysis improve sleep apnea. The impact of home dialysis on other sleep disorders and sleep complaints is less impressive, but the data, thus far, have been limited. Further research is required to evaluate the impact of home dialysis on all sleep disorders and sleep complaints in this patient population and to determine whether this improves quality of life and cardiovascular morbidity and mortality.

Abstract
AIM Sleep disorders are common in patients with end-stage renal disease. Although studies have been conducted on the type and frequency of sleep disturbances in hemodialysis and peritoneal dialysis patients, there has been no study comparing the sleep quality between these two groups. Therefore, we aimed to compare sleep quality between hemodialysis and peritoneal dialysis patients. METHODS A total of 102 patients (52 hemodialysis and 50 peritoneal dialysis) were included in the study. The Pittsburgh sleep quality index (PSQI) was used for the assessment of sleep quality. Two groups were compared for seven components of the PSQI questionnaire and global score as well as for clinical and laboratory findings. We also assessed the independent predictors of sleep quality. RESULTS There were 51 male and 51 female patients (29 male and 23 female in hemodialysis group versus 22 male and 28 female in peritoneal dialysis group). The mean age was 55.5+/-14.6 years in the hemodialysis and 51.5+/-18.1 years in the peritoneal dialysis group. The median dialysis duration was 36 (77.0) months. The sleep quality was poor in 88.5% of the hemodialysis patients and 78.0% of the peritoneal dialysis patients. However, this difference in sleep quality was not significant between the two groups (P>0.05). There was a significant association between the sleep quality and the age, presence of diabetes mellitus, and serum albumin. Among these variables, only age was found to be an independent predictor of sleep quality. CONCLUSIONS Hemodialysis and peritoneal dialysis patients had a similar high rate of poor sleep quality. Further studies are necessary to investigate the causes of poor quality of sleep and to investigate methods to improve sleep quality in this population.

Abstract
BACKGROUND Sleep disorders are common in hemodialysis (HD) patients. This study examined the relationship between quality of sleep (QoS) and religious/spiritual activity in HD patients. METHODS The study subjects were 861 HD patients from 14 dialysis clinics in Taiwan. QoS and religious/spiritual activity were evaluated by the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the Royal Free Questionnaire respectively. RESULTS There was no difference in clinical parameters between the good and poor sleepers. Although total scores of religious and spiritual activity did not correlate with global PSQI score, patients who held strong 'spiritual' beliefs reported more problems in 'sleep disturbances', while those who exercised religious beliefs more strongly reported less trouble in 'daytime dysfunction'. CONCLUSION There is no significant correlation between QoS and religious/spiritual activity globally. However, the spiritual and religious activity did associate with different components of QoS.

Abstract
Sleep-related complaints affect 50-80% of patients on dialysis. Sleep disorders impair quality of life significantly. Increasing evidence suggests that sleep disruption has a profound impact both on an individual and on a societal level. The etiology of sleep disorders is often multifactorial: biologic, social, and psychological factors play a role. This is especially true for insomnia, which is the most common sleep disorder in different populations, including patients on dialysis. Biochemical and metabolic changes, lifestyle factors, depression, anxiety, and other underlying sleep disorders can all have an effect on the development and persistence of sleep disruption, leading to chronic insomnia. Insomnia is defined as difficulty initiating or maintaining sleep, or having nonrestorative sleep. It is also associated with daytime consequences, such as sleepiness and fatigue, and impaired daytime functioning. In most cases, the diagnosis of insomnia is based on the patient's history, but in some patients objective assessment of sleep pattern may be necessary. Optimally the treatment of insomnia involves the combination of both pharmacologic and nonpharmacologic approaches. In some cases acute insomnia resolves spontaneously, but if left untreated, it may lead to chronic sleep problems. The treatment of chronic insomnia is often challenging. There are only a few studies specifically addressing the management of this sleep disorder in patients with chronic renal disease. Considering the polypharmacy and altered metabolism in this patient population, treatment trials are clearly needed. This article reviews the diagnosis of sleep disorders with a focus on insomnia in patients on dialysis.

Abstract
The aim of this study was to describe habitual sleep, daytime symptoms, sleep-disturbing factors, current sleep during 1 week and fatigue in patients with peritoneal dialysis treatment at home and also discover predictions for sleep quality outcome. The knowledge should increase possibilities for supportive nursing health care. Fifty-five patients answered two mailed questionnaires and filled in a sleep diary. Of these, 60% had moderate, persistent sleep problems combined with daytime symptoms. Nocturnal awakenings with difficulties falling asleep again and a sleep duration predicted as 57% of sleep quality. Nocturnal pruritus and 'difficulties finding a comfortable sleeping position' were significant sleep-disturbing factors. Sleep quality predictors means progress in knowledge about the complexity of the situation for peritoneal dialysis patients. Poor sleep, daytime symptoms, sleep-disturbing factors and chronic fatigue need to be enlightened, especially for the nephrology nurses who are in a unique position to give supportive nursing health care.

Abstract
Although sleep problems are thought to be prevalent among patients who undergo dialysis, there is only limited information on the determinants of sleep quality and the change in sleep quality during the first year of dialysis treatment. This report uses data from a national cohort study of incident hemodialysis and peritoneal dialysis patients to identify the correlates of sleep quality and to determine the extent to which sleep quality is related to patients' health-related quality of life and survival. This report includes 909 incident dialysis patients who responded to questions about sleep quality. Three quarters of incident dialysis patients reported impaired sleep, and 14% had a decline in sleep quality in the first year of treatment. Poor sleep quality was significantly related to black race, higher serum phosphate, current smoking, benzodiazepine prescription, and complaints of severe restless legs. Poor baseline sleep quality was associated with lower SF-36 physical and mental component summary scores, vitality scores, and bodily pain scores (all P < 0.001). Younger age, current smoking, and benzodiazepine prescription were associated with decreases in sleep quality at 1 yr. There was no association between baseline sleep quality and survival; however, a decline in sleep quality during the first year on dialysis was associated with shorter survival (hazard ratio 1.44; 95% confidence interval 1.13 to 1.83; P = 0.003). Future work should examine the link between sleep quality and daytime functioning in the kidney failure population and the extent to which improving sleep quality will improve dialysis patient outcomes.

Abstract
The past decade has seen an explosion of interest in both idiopathic and secondary restless legs syndrome (RLS). Secondary RLS occurs in patients with uremia, pregnancy, and iron deficiency. Patients experience an irresistible urge to move the legs that is worse during inactivity and at night. RLS affects 6.6% to 62% of patients on long-term dialysis therapy and is associated with a greater mortality risk. The wide range of reported prevalence is explained in part by variations in methods of diagnosis. The International Restless Legs Syndrome Study Group defined diagnostic criteria that have improved the quality of RLS research. Advanced neurological imaging techniques suggest the pathophysiological state of idiopathic RLS involves dysfunction of subcortical areas of the brain. Dopaminergic pathways and neuronal iron handling have been implicated. Limited studies of patients with uremic RLS suggested similar mechanisms, but anemia, hyperphosphatemia, and psychological factors also may have a role. The few clinical trials in uremic RLS suggest that treatment should involve the reduction of potential exacerbating agents (tricyclic antidepressants, selective serotonin uptake inhibitors, lithium, and dopamine antagonists), correction of anemia (with erythropoietin and iron), and use of levodopa or dopamine agonists. Other agents shown to be of benefit in idiopathic RLS can be tried, but may be limited by side effects in patients with uremia (benzodiazepines, opioids, gabapentin, carbamazepine, and clonidine). Symptoms of uremic RLS will disappear within a few weeks of successful renal transplantation. The progress made to date in unraveling the pathophysiological state of uremic RLS should stimulate additional research toward targeted therapy.
