Abstract
Sleep disorders are highly prevalent in chronic kidney disease (CKD) but are often under-recognized. Restless legs syndrome, which is common in CKD owing to issues with dopamine metabolism and is exacerbated by iron deficiency and uraemia, can lead to poor sleep quality and increased daytime fatigue. Insomnia is also prevalent in CKD, particularly in patients requiring dialysis, with increased sleep latency and sleep fragmentation being reported. The cause of insomnia in CKD is multifactorial - poor sleep habits and frequent napping during dialysis, uraemia, medications and mood disorders have all been suggested as potential contributing factors. Sleep apnoea and CKD are also now recognized as having a bi-directional relationship. Sleep apnoea is a risk factor for accelerated progression of CKD, and fluid overload, which is associated with kidney failure, can lead to both obstructive and central sleep apnoea. The presence of obstructive sleep apnoea in CKD can exacerbate the already heightened cardiovascular morbidity and mortality in these patients, as well as leading to daytime fatigue and reduced quality of life. Increased awareness, timely diagnosis and appropriate therapeutic interventions are essential to reduce the negative impact of sleep disorders in patients with kidney disease.

Association of healthy beverage index with circadian rhythm and quality of sleep among overweight and obese women: a cross-sectional study. Eat Weight Disord 2022; 27:2541-2550. [PMID: 35389150 DOI: 10.1007/s40519-022-01391-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 03/07/2022] [Indexed: 10/18/2022] Open
Abstract
PURPOSE Circadian rhythm is a behavioral, physiological, and molecular change with a cycle length of approximately 24 h. Changes to the circadian rhythm can result in sleep difficulty. The healthy beverage index (HBI) is a holistic concept for evaluating the quality of overall beverage intake and its association with health-related outcomes in nutritional epidemiological studies. This study aimed to assess the relationship of HBI with circadian rhythm and sleep quality among overweight/obese women. METHODS The current study was conducted among 208 overweight and obese women between 18-48 years in Tehran, Iran. We evaluated potential HBI with a valid food frequency questionnaire. Following standard procedures, trained personnel assessed anthropometric measures, blood samples, and other baseline characteristics. The Pittsburgh Sleep Quality Index and the morning-eveningness questionnaire were applied to evaluate sleep quality and circadian rhythm respectively. RESULTS The mean (SD) BMI for this study was 30.8 (4.2) kg/m2. We observed that subjects in the least tertile had significantly high levels of triglyceride (p = 0.04) and low-density lipoprotein (p = 0.009). High-density lipoprotein was significantly different across the tertiles (p = 0.003). After adjusting for potential covariates, subjects in the second tertile of HBI had 5.07 odds of having the worst quality of sleep as compared to those in the third tertile, p < 0.05. We also observed a significant inverse association between the HBI and the "moderately evening type" participants (OR 0.86; 95% CI 0.68-0.99; p: 0.02) after adjusting for potential confounders. CONCLUSION Healthy beverage consumption may have the potential of improving sleep quality among overweight and obese subjects. LEVEL OF EVIDENCE Level IV, evidence obtained from a descriptive study.

Abstract
BACKGROUND AND OBJECTIVES Patients of end-stage renal disease are prone to have a very low quality of life (QoL). Variety of factors influence the QoL among sufferers of chronic kidney disease comprising of type of dialysis, sufficiency/adequacy of dialysis, and associated burden of disease. We conducted this study amidst the pandemic to determine the associated factors for poor QoL in hemodialysis patients during the ongoing pandemic. PATIENTS AND METHODS This cross-sectional study was conducted in a hemodialysis unit of a tertiary care hospital. A total of 118 participants responded to the validated questionnaire of Quality of Life Index-dialysis version-III (QLI). Higher scores signify good QoL, total scores are further categorized into subgroups desirable, relatively desirable and undesirable. RESULTS The mean age of the participants was 57.36 ± 10.03 years and mean body mass index of 26.73 ± 5.54 kg/m2. The mean total QoL of the study population was found quite low (12.99 ± 5.89). Majority of respondents fell in undesirable category of QoL (49.2%). Total QoL (P = 0.004) and subscale health/functioning (P = 0.003) were significantly lower in females. All the subscales along with total QoL scores were found lower in twice-weekly dialyzed patients (P < 0.001). Marital status (P = 0.049) and twice-weekly dialysis (P < 0.001) were found significant with undesirable QoL. On multivariate analysis, significant determinants of undesirable QoL were twice-weekly dialysis (P = 0.001), catheter access (P = 0.034), phosphate (P = 0.005) and uric acid (P = 0.006). CONCLUSION Inadequate dialysis due to lesser frequency per week leading to poorly cleared toxic substances were most significant contributors of poor QoL in our study.

[PMID: 35683604 PMCID: PMC9181024 DOI: 10.3390/jcm11113218] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 05/28/2022] [Accepted: 06/02/2022] [Indexed: 02/04/2023] Open
Abstract
Alexithymia, or the inability to distinguish between bodily feelings and emotions, has been linked to poor sleep quality in some studies. Rare studies examined the associations between electrolyte phosphorus in patients on hemodialysis and their sleep quality, daytime sleepiness, and alexithymia with inflammatory factors. Hemodialysis is a treatment method for terminal renal patients that involves the diffusion of unwanted metabolic products through the dialyzer membrane. Our study aimed to examine whether there was a difference in phosphorus levels, inflammatory factors, and daytime sleepiness according to the hemodialysis patients’ levels of alexithymia. The study involved 170 HD patients that had been treated with chronic dialysis for more than three months. Prior to the hemodialysis procedure, laboratory findings were sampled. Respondents completed the Pittsburgh Sleep Quality Index, the Toronto Alexithymia Scale 26, and the Epworth Sleepiness Scale, and were questioned about depression. The results showed that alexithymic HD patients exhibited significantly higher leukocyte counts, lower predialysis phosphorus values, and more pronounced daily sleepiness than the alexithymia-free group (Mann−Whitney U test, p = 0.02, p = 0.005, and p < 0.001, respectively). We concluded that alexithymia was an independent predictor of high daytime sleepiness in HD patients (OR = 1.05, 95% CI 1.02 to 1.09).

Abstract
This study was carried out to evaluate the effect of acupressure applied to hemodialysis patients on the level of daytime sleepiness and sleep quality. The data were collected using the Descriptive Information Form, Pittsburgh Sleep Quality Index, and Epworth Sleepiness Scale. In the study, a total of 12 sessions of acupressure were applied to the Shenmen (HT7), Sanyingjao (Sp6), and Yungquan (KI1) points in the experimental group for 4 weeks. No intervention was applied to the control group. After the acupressure, it was determined that the sleep quality of the experimental group was better than that of the control group and that daytime sleepiness was less compared with the control group. After the acupressure, it was determined that the sleep latency of the experimental group was statistically significantly less and their total sleep duration was higher compared with the control group (P < .05). Although there was a decrease in the sleep quality of the experimental group 1 month after the cessation of the acupressure, it was determined that the sleep quality of the experimental group was better than that of the control group (P < .05). It was concluded that acupressure was an effective nursing intervention in increasing sleep quality and decreasing daytime sleepiness of hemodialysis patients.

Abstract
BACKGROUND Driving is a complex task requiring multiple cognitive domains and the musculoskeletal system. Cognitive dysfunction is associated with driving impairment. Dialysis patients are known to have a high prevalence of cognitive impairment and other comorbidities, and may be at risk of driving impairment. No Australian guidelines address driving safety in dialysis patients. AIMS To estimate the proportion of dialysis patients who were driving and those at risk of driving impairment, and to investigate the agreement between objective and subjective markers of risk. METHODS This single-centre study involved dialysis patients voluntarily completing two questionnaires relating to risk of driving impairment; the first questionnaire focussed on objective markers, and the second questionnaire focussed on subjective markers. Risk of driving impairment was established using pre-determined criteria, and the agreement between objective and subjective markers was estimated using Cohen kappa. RESULTS A total of 44.8% (99/221) of patients participated; 76.8% (76/99) of participants were driving, and 76.3% (58/76) of drivers were at risk of driving impairment. Factors associated with at-risk driving included post dialysis dizziness, leg weakness or numbness, falling asleep while driving and hypoglycaemia. Sixteen patients reported collisions since commencing dialysis. The questionnaires displayed slight agreement (Cohen kappa = 0.20) between objective and subjective markers. CONCLUSIONS Dialysis patients are at risk of driving impairment based on self-reported questionnaire responses. Discrepancies between patients' perceptions and objective markers were apparent. Further research into appropriate risk assessments, as well as development of guidelines to aid in determining driving safety in dialysis patients, is needed.

Abstract
Background and objectives Sleep disorders are prevalent in end-stage renal disease (ESRD) involving the majority of patients undergoing hemodialysis. The main objective of treating sleep disorders in patients of ESRD is to correct subjective and objective sleep quality, decrease fatigue and daytime sleepiness, and enhance daytime functioning. Irrespective of the adverse effects reported, benzodiazepines are widely utilized among patients with sleep disorders in end-stage renal disease. Melatonin is a newer agent being studied for use in hemodialysis patients for improvement of sleep quality. The aim of our observational study is to witness the effectiveness of both benzodiazepine and exogenous melatonin as a treatment of sleep disorders in patients undergoing hemodialysis. Materials and methods We conducted a comparative, observational study in ESRD patients who are on hemodialysis. These patients were selected from attendees of the hemodialysis unit, nephrology department of a tertiary care hospital, including those who were on regular hemodialysis, thrice-weekly in frequency for at least once per year, and taking regular sleep medications for at least three months with frequently reported drug dosages of alprazolam 0.5 mg once daily or melatonin 3 mg once daily (before bedtime). The subjective sleep assessment was done by utilizing four scales, including the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), and Stanford Sleepiness Scale (SSS). Results A total of 117 hemodialysis-dependent patients met the inclusion criteria, among whom 79 patients were using alprazolam while 38 were using melatonin for their disturbed sleep. The mean age of the study participants was 49.12 ± 12.75, comprising 72 males (61.53%) and 45 females (38.46%). The duration of the diagnosis of chronic kidney disease (CKD), duration of onset of hemodialysis, and estimated glomerular filtration rate (eGFR) was comparable in both groups. Both groups had similar laboratory markers except for higher hemoglobin in the melatonin group (p=0.028) and high parathyroid hormone (PTH) levels in the alprazolam group (p=0.001). PSQI scores were 8.76 ± 3.09 in the alprazolam group and 7.32 ± 2.65 in the melatonin group (p=0.015). In the sub-scores, there were no differences in sleep latency (p=0.481) and daytime dysfunction (p=0.662) while sleep efficiency (p=0.167) and subjective sleep quality (p=0.132) were not statistically significant. The significant differences were lower scores of sleep duration (p=0.040) and sleep disturbance (p=0.003) in the melatonin group. The ESS scores revealed no significant difference in either group (p=0.074). With respect to the ISI and SSS, higher scores were obtained in the alprazolam group. Overall, 89 study participants had reported poor sleep quality, out of which 81% were using alprazolam, and 65% were using melatonin (p=0.071). A total of 50 study participants exhibited excessive daytime sleepiness with 45% of them were using alprazolam and 36% were using melatonin. About 54% of the alprazolam using hemodialysis patients had moderate insomnia while 50% of the melatonin using patients had sub-threshold insomnia (p=0.062). Conclusion As melatonin use has shown better sleep quality and less insomnia severity as compared to alprazolam use in our study, it is postulated that the sleep-wake cycle should be commonly targeted by pharmacological therapy in ESRD.

Abstract
Sleep disorders in children with chronic kidney disease have been assessed in a limited number of studies. Our aim was to characterize the types of sleep disorders in children on regular hemodialysis and to detect the predictors of sleep efficiency in those children. Forty children and adolescents on regular hemodialysis and another 40 age- and gender-matched control groups were interviewed to answer a questionnaire-based survey, a modified Epworth Sleepiness Scale, to assess excess daytime sleepiness. Also, they underwent an overnight in-laboratory polysomnography to assess total sleep time, sleep efficiency, sleep staging, apnea/hypopnea index, and periodic limb movement index. We found poor sleep efficiency in 20% of cases, and periodic limb movement index higher than 5 in 45%, and apnea/hypopnea index higher than 5 in 40%. There was significant negative correlation between sleep efficiency on one hand, and serum potassium, serum creatinine, and sleep onset on other hand (p < 0.001, p < 0.001, and p < 0.001, respectively). There was significant decrease in hemoglobin, serum iron, and transferrin saturation in patients with excess daytime sleepiness (p < 0.001, p = 0.003, and p = 0.010, respectively). By using multivariate linear regression analysis, we found that serum creatinine was the single independent predictor of sleep efficiency.Conclusion: Poor sleep quality is not uncommon in hemodialysis children. Our results show a lower frequency of sleep disorders in comparison with previous studies. There is a strong association between kidney dysfunction and poor sleep quality in HD children.What is known:• Sleep disturbances can adversely affect a child's daytime performance.• Sleep disorders in children with chronic kidney disease have been assessed in only a limited number of studies.What is new:• Poor sleep quality is not uncommon in hemodialysis children.• There is a strong association between kidney dysfunction and poor sleep quality in hemodialysis children.

Abstract
OBJECTIVE Hemodialysis (HD) patients are exposed to dysregulated fluid balance which can lead to overhydration. Poor sleep quality and excessive daytime sleepiness are particularly common in these patients, however the relationship between fluid status and sleep quality and daytime sleepiness has not yet been studied. Therefore, the aim of this study is to evaluate the correlations between fluid status and sleep quality and daytime sleepiness in HD patients. METHOD This cross-sectional study included 115 HD patients and 30 healthy control subjects from the HD center of Shanghai Ninth People's Hospital. Fluid compartments [total body water (TBW)], extracellular water (ECW)] and overhydration index (OH) were analyzed by multifrequency bio-impedance (BCM). Overhydration was defined as OH/ECW≥7%. HD patients were divided into an overhydration group and non overhydration group according to OH/ECW. Sleep quality was assessed by the Chinese version of the Pittsburgh Sleep Quality Index (PSQI), and excessive daytime sleepiness was evaluated by the Epworth Sleepiness Scale (ESS). RESULTS The prevalence rate of fluid overload in HD patients was 65.2%. Poor sleep quality (PSQI≥5) and excessive daytime sleepiness (ESS≥11) were significantly higher in HD patients compared with the healthy controls [6 (3, 10) vs.2.11 ± 1.59, p = 0.000; 3 (0, 6) vs.1.68 ± 1.07, p = 0.045]. Furthermore, the PSQI scores were higher in HD patients with overhydration (7.8 ± 4.5 vs. 4.8 ± 3.2, p = 0.000). The component scores 1, 2, 3 and 5 of the PSQI showed significant differences between the overhydration and non overhydration groups. The ESS scores did not show differences between the two groups (3.9 ± 4.1 vs. 3.3 ± 3.5, p = 0.508). OH was correlated with Systolic BP and Diastolic BP, and additionally was an independent predictor of poor sleep quality. CONCLUSION Fluid overload is significantly linked with poor quality of sleep in HD patients, however there is no association with excessive daytime sleepiness. Our study provides new insight into possible treatment strategies. Future studies should examine the effects of optimizing fluid status on quality of sleep.

Abstract
Poor sleep and sleep-related breathing disorders are common in patients with end-stage renal disease (ESRD) but are often unrecognized and undertreated. Sleep disorders are known negative prognostic factors for morbidity and mortality. The most frequent sleep disorders seen in patients with ESRD are conditioned insomnia, excessive daytime sleepiness, obstructive or central sleep apnea (SA), as well as restless legs syndrome (RLS) and periodic limb movement disorder (PLMD). Several uremic and nonuremic factors are thought to participate in the pathogenesis of sleep disorders in patients with ESRD. The therapy of sleeping disorders includes nonpharmacological and pharmacological measures that can improve the functionality and quality of life in patients with ESRD.

Abstract
OBJECTIVE Resting energy expenditure (REE) and physical activity (PA) undergo variations during chemotherapy. The aim of this study was to use a metabolic Holter (SenseWear Armband [SWA]) to assess REE, total energy expenditure (TEE), and PA changes in patients undergoing chemotherapy to ensure the appropriate calorie intake. To our knowledge, this is the first study to do so. METHODS Eight patients with gastrointestinal tumors and a Karnofsky performance status of >50 underwent evaluation of the body mass index; REE, TEE, metabolic equivalent, and sleep efficiency were evaluated by SWA. Fat-free mass and fat mass were measured by bioelectrical impedance analysis, muscle strength by handgrip, and dietary intake by food diary. All evaluations were performed before chemotherapy (T0), at mid-treatment (T1), and at the end of treatment (T2). A calorie-equivalent diet to the TEE was recommended to all patients. RESULTS At T0, a body weight loss of 15.1 ± 7.2% in the previous 6 mo was observed in all patients. Two patients did not complete treatment. During chemotherapy, thanks to the nutritional counseling, the remaining patients increased their calorie intake (P = 0.006) and no significant change was observed in other parameters. The REE calculation measured by SWA was correlated to the Harris-Benedict formula (P ≤ 0.002). CONCLUSION The present data excluded significant variations of REE and PA in the course of chemotherapy in patients who do not experience weight loss and who have a Karnofsky performance status of >50. Nutritional counseling based on SWA measurements is useful to support nutritional status in patients undergoing chemotherapy.

Abstract
Previous studies have observed worse sleep quality in patients undergoing conventional dialysis as compared to daily dialysis. Our aim was to compare the sleep parameters of patients undergoing daily or conventional dialysis using an objective measure (actigraphy). This cross-sectional study was performed in three dialysis centers, including a convenience sample (nonprobability sampling) of 73 patients (36 patients on daily hemodialysis and 37 patients on conventional hemodialysis). The following parameters were evaluated: nocturnal total sleep time (NTST), expressed in minutes; wake time after sleep onset (WASO), expressed in minutes; number of nighttime awakenings; daytime total sleep time (DTST), expressed in minutes; number of daytime naps; and nighttime percentage of sleep (% sleep). The Mini-Mental State Examination and the Beck Depression Inventory were also administered. The mean age was 53.4 ± 17.0 years. After adjustment of confounding factors using multiple linear regression analysis, no difference in actigraphy parameters was detected between the groups: NTST (p = 0.468), WASO (p = 0.88), % sleep (p = 0.754), awakenings (p = 0.648), naps (p = 0.414), and DTST (p = 0.805). Different from previous studies employing qualitative analysis, the present assessment did not observe an influence of hemodialysis modality on objective sleep parameters in chronic renal patients.

Abstract
The purpose of this study was to conduct a systematic review of the available evidence on
sleep disorders in patients with end stage renal disease (ESRD) undergoing hemodialysis
(HD). [Subjects and Methods] Two independent reviewers performed a computer-assisted
search of the MEDLINE, SciELO, LILACS, and BIREME Virtual Health Library medical databases
from their inception to November 2015. [Results] One thousand one hundred twenty-six
articles were found that met the inclusion criteria. Articles were excluded if they were
not in English, the patients did not undergo HD, or the studies were not cross-sectional
or clinical trials. After reading the full text, a further 300 studies were excluded
because they did not use polysomnography. The remaining 18 studies with ESRD patients
undergoing HD comprised 8 clinical trials and 10 cross-sectional studies. This systematic
review followed the criteria outlined by the PRISMA declaration. [Conclusion] In this
systematic review, a high prevalence of sleep disorders was observed in ESRD, including
sleep-disordered breathing. This knowledge may enable health professionals to devise new
strategies for the diagnosis and treatment of these patients, in order to reduce morbidity
and mortality and improve their quality of life.

Abstract
INTRODUCTION Previous studies of patients with end-stage renal disease have examined the role of fluid shifts on apnea-hypopnea episodes, but the association between volume overload and patient-reported sleep quality or duration has not been well-established. METHODS We studied the association between predialysis bioimpedance spectroscopy-derived volume estimates and self-reported sleep quality and duration in 638 patients in the United States Renal Data System ACTIVE/ADIPOSE study receiving hemodialysis from 2009 to 2011. We used questionnaires to assess self-reported sleep duration and quality. We used relative hydration status (fluid overload/extracellular water; FO/ECW) as the primary predictor and examined associations with hours of sleep duration using linear regression. We used multivariable ordinal logistic regression to determine the association between categories of relative hydration status (normal hydration [FO/ECW < 6.8%], mild overhydration [FO/ECW 6.8%-15%], and hyperhydration [FO/ECW > 15%]) and four levels of difficulty with falling asleep, waking, and returning to sleep. FINDINGS Higher relative hydration status was associated with fewer hours of sleep (-0.31 hours per 10%, 95% confidence interval (CI) -0.49 to -0.13). Compared to the normal hydration group, there was a statistically significant association between higher relative hydration status category and more frequent nighttime waking (OR: mild overhydration 1.92 [95% CI 1.23-2.99], hyperhydration 1.87 [95% CI 1.16-2.99]), a trend toward more difficulty returning to sleep (OR: mild overhydration 1.46 [95% CI 0.94-2.27], hyperhydration 1.52 [95% CI 0.95-2.43]), and no association between relative hydration category and difficulty falling asleep. DISCUSSION Hydration status was associated with self-reported sleep duration in patients on dialysis. Future studies should prospectively examine the effects of optimizing fluid status on sleep duration and quality.

Abstract
As medical advances are made in the care of persons with chronic illnesses including those with end-stage renal disease (ESRD), patients are not only experiencing increasing life expectancy but also bearing the burden of illness and treatment for a longer duration of time. With this in mind, it is increasingly important for health care providers to pay close attention to their individual patient's perceptions of their health, fitness, life satisfaction, and well-being. This assessment of Health-Related Quality of Life (HRQOL) also includes an evaluation of the patient's level of satisfaction with treatment, outcome, and health status, also taking into account their perspective on future prospects. In addition to improving patient-provider communication by helping in the identification and prioritization of problems, it is important to note that high HRQOL has been shown to be associated with better medical outcomes, including reduction in hospitalizations and death. In this review, we outline several validated tools that are used to quantitatively measure HRQOL in the ESRD population and incorporate these instruments in a review of specific, evidence-based measures by which we can measurably improve health-related quality of life in dialysis patients.

Abstract
Background: This study was aimed to evaluate the prevalence of obstructive sleep apnea (OSA) and restless legs syndrome (RLS) in patients with end-stage renal disease (ESRD) after kidney transplantation. Materials and Methods: Two hundred kidney transplant recipients were enrolled in this cross-sectional study. Data on age, gender, etiology of ESRD, history of previous kidney transplantation, serum creatinine, and the presence or absence of OSA and RLS were collected. Symptoms of RLS were identified using the RLS questionnaire which was completed by the patients. The Berlin questionnaire and polysomnography were used for diagnosing OSA. Results: The mean age of the studied patients was 45.86 ± 10.24 years. The prevalence of OSA was 26% (52 of 200 studied patients) and of RLS was 51.5% (103 of 200 studied patients). Majority of the patients with high-risk OSA were male and significantly older than the patients with low-risk OSA (P < 0.05). The prevalence of RLS was higher in patients with high-risk OSA and a higher level of creatinine compared to that in those with a low risk of OSA (P < 0.0001). Level of creatinine in patients with positive RLS was significantly higher than in those with negative RLS (P < 0.0001). OSA was observed in almost 42% of patients with positive RLS, compared to 9% of patients with negative RLS (P < 0.0001). Conclusion: In summary, our results indicate that the prevalence of OSA and RLS in kidney transplant recipients was higher than in the general population. Also, there was a significant association between OSA and RLS in these patients.

Abstract
BACKGROUND Differential item functioning (DIF) occurs when members from different groups respond differently to particular items in a health-related quality of life (HRQoL) questionnaire after controlling for underlying HRQoL construct. This study aimed to assess DIF in the SF-36 questionnaire and its effect on comparing HRQoL scores across patients on HD and healthy people. METHODS One hundred fifty patients on maintenance hemodialysis (HD) and 642 healthy individuals filled out the Persian version of the SF-36 questionnaire. Multiple-group multiple-indicator multiple-causes (MG-MIMIC) model was used to assess DIF across patients on HD and healthy population. RESULTS Sixteen out of 36 (44.4 %) items were flagged with DIF. Six out of 16 items (37.5 %) were flagged with uniform DIF, nine items (56.2 %) with non-uniform DIF, and one item (6.2 %) with both uniform DIF and non-uniform DIF. DIF items were associated with all subscales with the exception of the limitation due to physical problems and bodily pain subscales. The significant lower HRQoL scores of patients on HD in comparison with healthy people in the physical functioning and vitality subscales did not change after removing the items with uniform DIF. CONCLUSIONS Our findings revealed that patients on HD and healthy people perceived the meaning of the items in SF-36 questionnaire differently. Although the impact of DIF is minimal, the cross-group comparison across patients on HD and healthy people should be performed with caution.

Abstract
BACKGROUND End stage renal disease negatively affects the patients' quality of life. There are different educational methods to help these patients. This study was performed to compare the effectiveness of self-care education in two methods, face to face and video educational, on the quality of life in patients under treatment by hemodialysis in education-medical centers in Urmia. METHODS In this quasi-experimental study, 120 hemodialysis patients were selected randomly; they were then randomly allocated to three groups: the control, face to face education and video education. For face to face group, education was given individually in two sessions of 35 to 45 minutes. For video educational group, CD was shown. Kidney Disease Quality Of Life- Short Form (KDQOL-SF) questionnaire was filled out before and two months after the intervention. Data analysis was performed in SPSS software by using one-way ANOVA. RESULTS ANOVA test showed a statistically significant difference in the quality of life scores among the three groups after the intervention (P=0.024). After the intervention, Tukey's post-hoc test showed a statistically significant difference between the two groups of video and face to face education regarding the quality of life (P>0.05). CONCLUSION Implementation of the face to face and video education methods improves the quality of life in hemodialysis patients. So, it is suggested that video educational should be used along with face to face education.

Abstract
The quality of life of hemodialysis (HD) patients is hampered by reduced nocturnal sleep quality and excessive daytime sleepiness. In addition to the sleep/wake cycle, levels of circadian biomarkers (e.g. melatonin) are disturbed in end-stage renal disease (ESRD). This suggests impaired circadian clock performance in HD patients, but the underlying mechanism is unknown. In this observational study, diurnal rhythms of sleep, serum melatonin and cortisol concentrations and clock gene mRNA expression are compared between HD patients (n = 9) and healthy control subjects (n = 9). In addition, the presence of circulating factors that might affect circadian rhythmicity is tested in vitro with cell culture experiments. Reduced sleep quality (median sleep onset latency [interquartile range] of 23.9 [17.3] min for patients versus 5.0 [10] minutes for controls, p < 0.01; mean (± SD) sleep efficiency 70.2 ± 8.1% versus 82.9 ± 10.9%, p = 0.02 and mean awake minutes after sleep onset 104.8 ± 27.9 versus 54.6 ± 41.6 minutes, p = 0.01) and increased daytime sleepiness (mean Epworth Sleepiness Score of 10.0 ± 4.8 versus 3.9 ± 2.0, p < 0.01) were confirmed in HD patients. Reduced nocturnal melatonin concentrations (1 AM: 98.1 [122.9] pmol/L versus 12.5 [44.2] pmol/L, p = 0.019; 5 AM: 114.0 [131.6] pmol/L versus 11.8 [86.8] pmol/L, p = 0.031) and affected circadian control of cortisol rhythm and circadian expression of the clock gene REV-ERBα were found. HD patient serum had a higher capacity to synchronize cells in vitro, suggesting an accumulated level of clock resetting compounds in HD patients. These compounds were not cleared by hemodialysis treatment or related to frequently used medications. In conclusion, the abovementioned results strongly suggest a disturbance in circadian timekeeping in peripheral tissues of HD patients. Accumulation of clock resetting compounds possibly contributes to this. Future studies are needed for a better mechanistic understanding of the interaction between renal failure and perturbation of the circadian clock.

Abstract
Restless legs syndrome (RLS) is a common neurologic sensorimotor disorder. It is also seen in hemodialysis patients in whom the mechanism is not thoroughly understood. The aim of this study was to evaluate the association between malnutrition-inflammation score (MIS), sleep quality, and RLS in chronic hemodialysis patients. This cross-sectional study included 232 adult stable chronic hemodialysis patients (mean age 60.9 ± 14.1 years, 56.5% male). RLS frequency, MIS, Pittsburgh Sleep Quality Index (PSQI), laboratory data of patients as well as severity of RLS were evaluated. Thirty-seven patients (15.9%) were diagnosed with RLS. Mean MIS of patients with or without RLS were similar. PSQI of patients with RLS was significantly higher than patients without RLS (P = 0.002). There was a significant positive correlation between RLS severity and PSQI (r = 0.445, P = 0.006). A significant positive correlation was also found between PSQI and MIS in patients with RLS (r = 0.419, P = 0.010). RLS severity was positively correlated with some inflammatory parameters such as white blood cell count and C-reactive protein (r = 0.427, P = 0.008 and r = 0.418 P = 0.010). PSQI was found as an independent significant predictor of RLS (odds ratio [OR] = 1.15 (1.06-1.25), P = 0.001) in multivariate logistic regression analysis. Our study revealed that there was no significant relationship between RLS and MIS in chronic hemodialysis patients. However, RLS severity is correlated with inflammatory parameters. Also, sleep quality in chronic hemodialysis patients with RLS is negatively associated with MIS.

Abstract
Inadequate sleep has been identified as a risk factor for a variety of health consequences. For example, short sleep durations and daytime sleepiness, an indicator of insufficient sleep and/or poor sleep quality, have been identified as risk factors for hypertension in the adult population. However, less evidence exists regarding whether these relationships hold within child and early adolescent samples and what factors mediate the relationship between sleep and risk for hypertension. Using data from the Study of Early Child Care and Youth Development, the present study examined body mass index (BMI) as a possible mediator for the effects of school-night sleep duration, weekend night sleep duration, and daytime sleepiness on risk for hypertension in a sample of sixth graders. The results demonstrated gender-specific patterns. Among boys, all three sleep characteristics predicted BMI and yielded significant indirect effects on risk for hypertension. Oppositely, only daytime sleepiness predicted BMI among girls and yielded a significant indirect effect on risk for hypertension. The findings provide clarification for the influence of sleep on the risk for hypertension during early adolescence and suggest a potential need for gender-specific designs in future research and application endeavors.

Abstract
BACKGROUND Sleep disturbance is an important medical problem in patients with end-stage renal disease. It might be related to the disruption of the body's circadian clock since nocturnal levels of its key biomarker melatonin are markedly reduced. We aimed at investigating whether a change in renal function due to kidney transplantation or donation would modify sleep, melatonin levels, circadian rhythmicity, and quality of life in kidney transplant recipients (KTR) and living donors (LD). METHODS In KTR, we assessed saliva melatonin concentrations, sleep quality and daytime sleepiness prior to and at 2 weeks and 3 months after transplantation. In LD, we assessed these parameters prior to and at 3 months after donation. We additionally assessed 24-hour core body temperature (cBT), 24-hour blood pressure profile, and quality of life (QoL) prior to and 3 months after transplantation. RESULTS Twenty-three KTR and 23 LD completed the study. Regarding sleep, the amount of nighttime awake minutes tended to be reduced in recipients after transplantation (p = 0.05). Nocturnal melatonin concentrations did not change with transplantation or donation. Blood pressure dipping profile and the two circadian markers dim-light melatonin onset and time of core body temperature minimum did not change. Nevertheless, KTR reported that daytime sleepiness and QoL had improved. CONCLUSION Objectively nocturnal sleep quality marginally improved after transplantation. Subjectively patients reported improved QoL and daytime sleepiness scores. Changes in renal function were not associated with modified melatonin secretion or circadian rhythmicity.

Abstract
AIM The disturbed circadian rhythm in haemodialysis patients results in perturbed sleep. Short term melatonin supplementation has alleviated these sleep problems. Our aim was to investigate the effects of long-term melatonin supplementation on quality of life and sleep. METHODS In this randomized double-blind placebo-controlled trial haemodialysis patients suffering from subjective sleep problems received melatonin 3 mg day(-1) vs. placebo during 12 months. The primary endpoint quality of life parameter 'vitality' was measured with Medical Outcomes Study Short Form-36. Secondary outcomes were improvement of three sleep parameters measured by actigraphy and nighttime salivary melatonin concentrations. RESULTS Sixty-seven patients were randomized. Forty-two patients completed the trial. With melatonin, no beneficial effect on vitality was seen. Other quality of life parameters showed both advantageous and disadvantageous effects of melatonin. Considering sleep, at 3 months sleep efficiency and actual sleep time had improved with melatonin compared with placebo on haemodialysis days (difference 7.6%, 95% CI 0.77, 14.4 and 49 min, 95% CI 2.1, 95.9, respectively). At 12 months none of the sleep parameters differed significantly from placebo. Melatonin salivary concentrations at 6 months had significantly increased in the melatonin group compared with the placebo group. CONCLUSIONS The high drop-out rate limits the strength of our conclusions. However, although a previous study reported beneficial short term effects of melatonin on sleep in haemodialysis patients, in this long-term study the positive effects disappeared during follow up (6-12 months). Also the quality of life parameter, vitality, did not improve. Efforts should be made to elucidate the mechanism responsible for the loss of effect with chronic use.

Abstract
BACKGROUND Today, despite remarkable advances in the care of hemodialysis patients, the quality of life (QOL) for these patients is still unsatisfactory. Although previous reports confirmed the effect of exercise on the well-being of renal patients, less than 50% of end-stage kidney patients participate in a regular sports program. Tai chi is a slow and gentle exercise that is suitable for people with chronic illnesses and those with severe intolerance of exercise. Therefore, this study aimed to determine the effect of tai chi exercise on the QOL of hemodialysis patients. MATERIALS AND METHODS This was a quasi-experimental study conducted in a single group and in two steps. Twenty-five hemodialysis patients, admitted to hospitals in Isfahan, Iran, were selected, and their QOL was compared before and after intervention in two domains of satisfaction and importance. Convenience sampling was used. The sampling was convenience. The subjects were trained in the intervention through a single session of tai chi exercise class for one hour weekly, for 12 weeks, with a training compact disc (CD) that helped the patients to exercise at least twice a week at home. Data were collected by the completion of a demographic characteristics form and a researcher-made QOL questionnaire adopted from Ferrans and Powers Quality of Life Index Dialysis Version and the Kidney Disease Quality of Life-Short Form (KDQOL-SF) questionnaire by the researchers. The data were analyzed by a paired t-test through SPSS software version 18. RESULTS Data analysis showed that there was a statistically significant difference in health and functioning (P < 0.001), socioeconomic (P < 0.001), and psychospiritual (P < 0.001) dimensions, and the family dimension had P = 0.002 in the satisfaction domain and P = 0.008 in the importance domain; the total score of quality of life in both domains was P < 0.001. CONCLUSIONS According to the research findings, tai chi exercise improves the QOL score significantly in all dimensions, and adding tai chi classes to the rehabilitation program of hemodialysis patients can have a positive effect including an improved QOL for them. Therefore, this study supports the results of other research studies that showed positive effects of tai chi on QOL.

Abstract
OBJECTIVE To describe the prevalence and severity of periodic limb movements during sleep in amyotrophic lateral sclerosis patients and to explore this fact as a predictor of severity of the condition with respect to mortality. METHODS In this case-control study, questionnaire and polysomnographic data were analyzed from 35 amyotrophic lateral sclerosis patients. Controls were matched by age, genre, and body mass index. A Kaplan-Meier curve was used to compare the survival time of patients with periodic limb movements of sleep index below or above 5. RESULTS The number of amyotrophic lateral sclerosis patients with an index greater than five was higher than controls (19 (53%) versus 4 (11%); p < 0.0001), and the mean index was higher (23.55 ± 40.07 versus 3.28 ± 8.96; p = 0.0009). Earlier mortality was more common in patients with more than five periodic limb movements per hour of sleep than patients with less than five periodic limb movements per hour of sleep (7/19 (37%) versus 1/16 (6%); p = 0.04) in this group of patients that had a mean survival of 33 months. CONCLUSIONS There were more periodic limb movements of sleep in amyotrophic lateral sclerosis patients than in the control population. The higher number of these movements in amyotrophic lateral sclerosis patients correlates with disease severity and may suggest poor survival.

Abstract
INTRODUCTION Despite many advances in the treatment of chronic renal failure, the quality of sleep in patients who suffer from this disease is at the risk. The high prevalence of sleep disorders in hemodialysis patients, which is concomitant with physical, behavioral, and psychological problems, has always affected these patients' quality of life (QOL). This study aimed to determine the relationship between quality of sleep and quality of life in hemodialysis patients. METHODS By using a descriptive and correlational design, this study was conducted on 245 hemodialysis patients in 2012. Patients were selected by convenience sampling from the hemodialysis ward of four training hospitals of Tabriz and Maragheh. Quality of sleep was measured by the Pittsburgh Sleep Quality Index (PSQI), and the quality of life for patients was measured by the Kidney Disease Quality Of Life questionnaire (KDQOL-SF). RESULTS 83.3% of hemodialysis patients had poor quality of sleep. Poor quality of life was significantly associated with poor quality of sleep. There was a significant negative correlation between global PSQI and important aspects of quality of life including physical health, symptoms and problems, the impact of kidney disease on daily life, burden of kidney disease, mental health, social support, and sexual function. CONCLUSION The low quality of sleep in hemodialysis patients has an effect on the deterioration of their quality of life. Therefore, training, counseling, and advocacy programs should be developed to improve the patients' quality of sleep and quality of life, especially those with lower education level and income, and older people.

Abstract
BACKGROUND This study aimed to assess the psychometric properties of the Persian version of the Ferrans and Powers 3.0 quality of life index (dialysis type) in patients receiving hemodialysis (HD) in order to describe their health-related quality of life (HRQOL). METHODS The sample (n = 150) consisted of adult HD patients receiving HD for at least 6 months from the establishment of the study. A total of 88 men and 62 women, with an average age of 50.47, from Shiraz, southern Iran, were enrolled in this study. The questionnaire was translated into Persian language using back translation and bilingual techniques. Convergent, discriminant, and construct validity of the Ferrans and Powers 3.0 dialysis version was evaluated. To check the internal consistency of the data, Cronbach's alpha, which indicates the reliability of the data, was used for the entire questionnaire and for the subscales. RESULTS The convergent and discriminant validity and success scaling rate for both sexes were 100 %. Cronbach's alpha was 0.95 overall, which was greater than 0.7 for all the subscales except for the family subscale. Our results suggest that HD patients in southern Iran have higher HRQOL scores when compared with those in other countries. Despite the higher mean HRQOL score for men compared with women, men had significantly higher HRQOL scores only in the health and functioning subscale. There was no significant correlation between HD patients' HRQOL and educational level. CONCLUSION The Persian version of Ferrans and Powers 3.0 has sufficient reliability and validity for measuring the quality of life of Persian-speaking HD patients. Female HD patients need more support and attention from family and society.

Abstract
Chronic Kidney Disease (CKD) has a tremendous psychological burden, which sometimes is overlooked or underestimated in the daily clinical routine practice, since in the health care process physicians prefer to focus on the objective aspects of the pathology. In this contribution, we make a systematic overview of the relationship between spirituality/religiosity and CKD, an emerging theme which only recently has raised interest from the scientific community despite its importance. We investigate different variables, axis and categories (from the quality of life to customer’s satisfaction, treatment adherence and therapeutic alliance, clinical parameters, as well as overall survival, and coping strategies adopted by the patient). Moreover, we underpin the principal clinically relevant implications (like the possibility of psycho-therapeutic interventions based on the spiritual and religious attitudes of the patient) and we discuss the main gaps, methodological barriers and difficulties in the field, fostering and advocating further research and clinical studies. This last aspect, together with the quality assessment of the studies, will be further explored in the second part of the study.

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
AIMS Our study investigated the role of circadian rhythm in the pathogenesis of sleep disturbance in patients with chronic kidney disease (CKD) based on an animal model. MAIN METHODS Sixteen Sprague-Dawley (SD) rats (eight from 5/6 nephrectomized CKD group and eight from control group) were used for electroencephalography (EEG) and electromyography (EMG) recording. Eight rats (four from CKD and four from control group) were sacrificed at six Zeitgeber time (ZT) points and determined the mRNA expression of clock genes, rPer1, rPer2 and rBMAL1b in the hypothalamus. KEY FINDINGS Our results demonstrated that both slow wave sleep (SWS) and rapid eye movement (REM) sleep were significantly increased in the ZT22-24 Zeitgeber time point of the dark period in the CKD rats when compared with those sleep architectures obtained from the control rats. The CKD-induced sleep disruptions were associated with significant upregulations of rPer1 (in ZT2, ZT6 and ZT14) and rPer2 mRNA expression (in ZT2 and ZT14) in the hypothalamus. SIGNIFICANCE Our study elucidated that the increases of SWS and REM sleep during ZT22-24 of the dark period in the CKD rats might be due to the enhancement of rPer1 and rPer2 clock genes in the hypothalamus, suggesting that disrupted circadian rhythm plays a role in the pathogenesis of sleep disturbance in patients with CKD.

Abstract
OBJECTIVE Impaired sleep has potential health consequences in chronic hemodialysis patients. To date, this issue has not been examined in studies involving a large number of subjects. This study aimed to identify factors associated with poor sleep quality and excessive day-time sleepiness (EDS) in dialysis patients. MATERIAL AND METHODS This cross-sectional observational study involved 400 patients (59% male) from three hemodialysis centers (SD-HEMOFOR). Quality of sleep was evaluated by the Pittsburgh Sleep Quality Index (PSQI), EDS by the Epworth Sleepiness Scale (ESS), risk of obstructive sleep apnea (OSA) by the Berlin questionnaire and comorbidity severity by the Charlson Comorbidity Index (CCI). RESULTS Poor sleep quality (PSQI >5) was found in 227 individuals (57%) and was associated with older age (p = 0.001), diabetes (p = 0.03), heart failure (p < 0.005), hypoalbuminemia (p = 0.01), low transferrin saturation (TSAT) (p = 0.009), higher CCI score (p = 0.01) and depression (p < 0.005). Independent factors were older age, heart failure, low TSAT and depressive symptoms. Day-time somnolence was present in 108 patients (27%) and was independently associated with stroke [odds ratio (OR) = 2.84, CI 1.03-7.76), lower hemoglobin concentration (OR = 2.45, CI 0.95-3.03) and high risk of OSA (OR = 1.65, CI 1.03-2.63). High risk of OSA (n = 120; 30%), was associated with hypertension (p < 0.001), overweight/obesity (p = 0.001), older age (p = 0.003) and symptoms of depression (p = 0.01). CONCLUSIONS Poor sleep quality and EDS were prevalent on chronic hemodialysis. Heart failure, low TSAT and depressive symptoms were independently associated with poor sleep quality. Stroke, anemia and high risk of OSA were independently associated with EDS. These results provide new insight into possible treatment strategies.

Abstract
BACKGROUND Many patients with end-stage renal disease who are undergoing chronic hemodialysis suffer from sleep disturbance. This paper was designed to study the severity and prevalence of sleep disorders and the factors affecting the syndromes in this unique patient group. METHODS We conducted this study by the use of questionnaires. Included in this study were a total of 245 patients at our center who had end-stage renal disease (ESRD) and who received hemodialysis thrice weekly for more than three months. Their demographic data and biochemical and hematologic parameters were analyzed. All patients were asked to complete two questionnaires (in a Chinese version) of the Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory second edition (BDI-II), either by themselves or with assistance from the medical staff. RESULTS One hundred and sixty-four patients completed both questionnaires with a response rate of 70.4%. Their mean age was 57.9 +/- 11.8 (ranging from 23.1 to 83.7) years old. They had been receiving hemodialysis for an average of 49.1 +/- 50.9 months before the study. The male to female ratio was 77:87. Seventy six (46.3%) patients had diabetes mellitus. The prevalence of sleep disturbance was 74.4% (122/164), defined as PSQI scores >5. The poor sleepers had higher BDI scores and a higher ratio of females comparing to the good sleepers. By a multivariate analysis, the BDI scores and female sex were the independent predictors of the patients being poor sleepers. In analyzing the poor sleepers, the BDI scores, durations of hemodialysis and hemoglobin levels were the independent factors for predicting the global PSQI scores. CONCLUSION The questionnaire showed a high prevalence of insomnia in the dialytic population. The study also attributes a predictive role in sleep quality to gender, depression, dialytic duration, and hemoglobin levels. The data indicate that in the management of insomnia in this patient group, anemia and depression, both of which are potentially correctable, should be assessed.

Abstract
BACKGROUND Patients with kidney failure have more sleep symptoms than the general population, but the contribution to sleep symptoms of kidney failure versus its treatment with thrice-weekly hemodialysis has been unclear. We assessed the influence of hemodialysis on sleep/wake behavior by using wrist actigraphy and self-reported sleep quality compared with patients with chronic kidney disease (CKD) stages 4 to 5. STUDY DESIGN Cross-sectional study. SETTING & PARTICIPANTS Thirty-six patients with CKD stages 4 to 5 and 51 hemodialysis (HD) patients wore wrist actigraphs and completed sleep diaries for 2 weeks. PREDICTORS Thrice-weekly HD versus CKD stages 4 to 5, unstable total sleep times (TSTs), early HD shift. OUTCOMES Self-reported sleep quality and objective measures of sleep/wake behavior. MEASUREMENTS Diaries, sleep questionnaires, and wrist actigraphy were performed. RESULTS The group with CKD stages 4 to 5 had an average age of 51 years, 69% were men, 19% were African American, and average body mass index was 28.9 kg/m2. The HD group had an average age of 54 years, 60.8% were men, 49% were African American, and average body mass index was 27.5 kg/m2. Average TST was 66.8 minutes shorter and sleep efficiency was 5.2% lower in the HD group compared with the population with CKD stages 4 to 5. In the HD population, 28 individuals had a mean change in TST greater than 60 minutes between HD and non-HD nights, and this unstable sleep pattern was associated with daytime sleepiness. The early-HD group had TST 62 minutes (95% confidence interval, approximately 22 to 102) shorter than those with later HD shifts. No significant differences in sleep efficiency or fragmentation index were found between the early- and late-HD groups. LIMITATIONS Study included those older than 18 years. CONCLUSIONS Both patients with CKD stages 4 to 5 and HD patients have short and fragmented sleep. An early-morning HD shift was associated with shorter TST and greater variation in nightly TST. Additional trials of the possible beneficial effect of behavioral sleep interventions, more frequent HD, and later HD shifts on sleep patterns are needed.

Evaluation of the reliability and validity of the Medical Outcomes Study sleep scale in patients with painful diabetic peripheral neuropathy during an international clinical trial. Health Qual Life Outcomes 2008; 6:113. [PMID: 19091084 PMCID: PMC2637242 DOI: 10.1186/1477-7525-6-113] [Citation(s) in RCA: 73] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2008] [Accepted: 12/17/2008] [Indexed: 11/11/2022] Open
Abstract
Background Sleep is an important element of functioning and well-being. The Medical Outcomes Study Sleep Scale (MOS-Sleep) includes 12 items assessing sleep disturbance, sleep adequacy, somnolence, quantity of sleep, snoring, and awakening short of breath or with a headache. A sleep problems index, grouping items from each of the former domains, is also available. This study evaluates the psychometric properties of MOS-Sleep Scale in a painful diabetic peripheral neuropathic population based on a clinical trial conducted in six countries. Methods Clinical data and health-related quality of life data were collected at baseline and after 12 weeks of follow-up. Overall, 396 patients were included in the analysis. Psychometric properties of the MOS-Sleep were assessed in the overall population and per country when the sample size was sufficient. Internal consistency reliability was assessed by Cronbach's alpha; the structure of the instrument was assessed by verifying item convergent and discriminant criteria; construct validity was evaluated by examining the relationships between MOS-Sleep scores and sleep interference and pain scores, and SF-36 scores; effect-sizes were used to assess the MOS-Sleep responsiveness. The study was conducted in compliance with United States Food and Drug Administration regulations for informed consent and protection of patient rights. Results Cronbach's alpha ranged from 0.71 to 0.81 for the multi-item dimensions and the sleep problems index. Item convergent and discriminant criteria were satisfied with item-scale correlations for hypothesized dimensions higher than 0.40 and tending to exceed the correlations of items with other dimensions, respectively. Taken individually, German, Polish and English language versions had good internal consistency reliability and dimension structure. Construct validity was supported with lower sleep adequacy score and greater sleep problems index scores associated with measures of sleep interference and pain scores. In addition, correlations between the SF-36 scores and the MOS-Sleep scores were low to moderate, ranging from -0.28 to -0.53. Responsiveness was supported by effect sizes > 0.80 for patients who improved according to the mean sleep interference and pain scores and clinician and patient global impression of change (p < 0.0001). Conclusion The MOS-Sleep had good psychometric properties in this painful diabetic peripheral neuropathic population. Trial registration As this study was conducted from 2000 to 2002 (i.e., before the filing requirement came out), no trial registration number is available.

Abstract
Symptoms are increasingly recognized as problematic for patients with end-stage renal disease (ESRD) treated with dialysis. Sleep disorders are common in ESRD patients treated with dialysis and are associated with patients' perceptions of quality of life, assessed by diverse measures, as well as depressive affect. Sleep disorders appear to be equally prevalent in peritoneal dialysis (PD) and hemodialysis (HD) patients. Treatment for sleep disorders in dialysis patients depends on establishing the diagnosis, often in a sleep laboratory, using polysomnography. Reversing coexistent medical and psychological disorders is important. The sleep apnea syndrome (SAS) can be treated with continuous positive airway pressure in dialysis patients, but conventional hemodialytic techniques have little effect on its severity. In contrast, nocturnal HD and transplantation appear to have important beneficial effects on sleep disordered breathing in ESRD patients. Although pain has been appreciated as a problem for ESRD patients for more than 20 years, few studies exist on this subject. Pain appears to be an underappreciated problem for ESRD patients. More research must be performed on the problem of pain in patients with chronic kidney disease (CKD).

Abstract
BACKGROUND Studies examining sleep in the hemodialysis (HD) population have largely lacked an adequate comparison group. It therefore is uncertain whether poor sleep quality in the HD population reflects age, chronic health conditions, or effects of conventional HD therapy. STUDY DESIGN Cross-sectional matched-group study. SETTING & PARTICIPANTS Forty-six in-center HD patients were compared with 137 community participants participating in the Sleep Heart Health Study matched for age, sex, body mass index, and race. PREDICTOR HD patients compared with community-dwelling non-HD participants. OUTCOMES & MEASUREMENTS Home unattended polysomnography was performed and scored by using similar protocols. Sleep habits and sleepiness were assessed by using the Sleep Habits Questionnaire and Epworth Sleepiness Scale. RESULTS Average age of study samples was 63 years, 72% were white, and average body mass index was 28 +/- 5 kg/m(2). HD patients were significantly more likely than community participants to have short sleep (odds ratio, 3.27; 95% confidence interval, 1.16 to 9.25) and decreased sleep efficiency (odds ratio, 5.5; 95% confidence interval, 1.5 to 19.6). HD patients reported more difficulty getting back to sleep (odds ratio, 2.25; 95% confidence interval, 1.11 to 4.60) and waking up too early (odds ratio, 2.39; 95% confidence interval, 1.01 to 5.66). There was no association between polysomnography sleep time and self-reported sleep time (r = 0.09; P = 0.6) or between the Epworth Sleepiness Scale and severity of sleep apnea (r = 0.10; P = 0.5) in the HD population. LIMITATIONS The study was limited to participants older than 45 years. CONCLUSIONS Kidney failure treated with thrice-weekly HD is significantly associated with poor subjective and objective sleep quality.

Abstract
While there is a significant body of literature documenting the impairments in health-related quality of life (HRQOL) experienced by patients with end-stage renal disease (ESRD), recent work has helped to elucidate the mediators of impaired well-being in this patient group. Physical and emotional symptoms have been shown to be common, frequently severe, and directly linked with impaired HRQOL. The following review explores the process of symptom assessment in patients with chronic kidney disease (CKD), presents an overview of the composite burden and importance of symptoms in patients with ESRD, highlights particularly common and distressing symptoms for which existing treatment strategies may be applicable, and discusses future directions for efforts to address and alleviate symptoms in the growing population of patients who suffer from CKD.

Abstract
BACKGROUND Although the arteriovenous fistula (AVF) is the recommended form of vascular access for patients with ESRD, its impact on patient perception of health status, quality of life (QOL), or satisfaction is unknown. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS This study compared patient-reported health status and QOL scores and vascular access type among a national random sample of 1563 patients at dialysis initiation and day 60 of ESRD during 1996 to 1997. Patients were stratified into five categories: AVF at first dialysis and day 60 of ESRD, arteriovenous graft (AVG) at first dialysis and day 60, central venous catheter (CVC) at first dialysis and AVF at day 60, CVC at first dialysis and AVG at day 60, and CVC at first dialysis and day 60. RESULTS Ten percent (n = 154) of patients had an AVF, 21% (n = 326) had an AVG, and 69% (n = 1083) had a CVC at dialysis initiation; those who were most likely to use an AVF were white and male. After statistical adjustment, patients with persistent AVF use reported greater physical activity and energy, better emotional and social well-being, fewer symptoms, less effect of dialysis and burden of kidney disease, and better sleep compared with patients with persistent CVC use, whereas measures such as cognitive and sexual function did not differ by access type. CONCLUSIONS Compared with persistent CVC use, early persistent AVF use is associated with the perception of improved health status and QOL among patients with ESRD. Future longitudinal studies may help to clarify further the association between QOL and vascular access.

Abstract
Sleep disorders are associated with impaired cognition in the general population, but little attention has been given to the potential association between sleep and cognitive function in the dialysis population. This study investigated reported sleep difficulty and cognitive function scores in a national cohort of patients who initiated maintenance hemodialysis and peritoneal dialysis. The cognitive function scale of the Kidney Disease Quality of Life instrument (KDQOL-CF), which measures aspects of cognitive ability that are important for daily functioning (perceived reaction time, ability to concentrate, and tendency to become confused), was used. The study population included 2286 patients who responded to a questionnaire at baseline in the US Renal Data System Dialysis Morbidity and Mortality Study Wave 2. Reported sleep difficulty was associated in a univariate manner with lower KDQOL-CF score. In a multivariable regression analysis that controlled for age, gender, race, education, diabetic ESRD, cardiovascular comorbidity, smoking, hemoglobin, serum albumin, prescribed sleep medications, dialysis modality, pre-ESRD care, bodily pain, and depressed mood, the association of sleep difficulty with KDQOL-CF score remained significant (P < 0.0001); the association also was significant in a multivariable analysis that was restricted to hemodialysis patients and included adjustment for Kt/V (P = 0.001). Depressed mood and sleep medication prescription predicted a lower KDQOL-CF score, and higher educational level and less bodily pain predicted a higher KDQOL-CF score. Increased understanding of links among sleep difficulty, management of sleep difficulty, and cognitive function could benefit multiple dimensions of dialysis patients' quality of life and daily functioning.

Abstract
Sleep-disordered breathing (SDB) has been noted commonly in hemodialysis (HD) patients, but it is not known whether this is related directly to the treatment of kidney failure with HD or to the higher prevalence of obesity and older age. Forty-six HD patients were compared with 137 participants from the Sleep Heart Health Study (SHHS) who were matched for age, gender, body mass index (BMI), and race. Home unattended polysomnography was performed and scored using similar protocols. The study sample was 62.7 +/- 10.1 yr, was predominantly male (72%) and white (63%), and had an average BMI of 28 +/- 5.3 kg/m(2). The HD sample had a higher systolic BP (137 versus 121 mmHg; P < 0.01) and a higher prevalence of diabetes (33 versus 9%; P < 0.01) and cardiovascular disease (33 versus 13%; P < 0.01) compared with the SHHS sample. The HD group had significantly less sleep time (320 versus 379 min; P < 0.0001) but similar sleep efficiency. HD patients had a higher frequency of arousals per hour (25.1 versus 17.1; P < 0.0001) and apnea-hypopneas per hour (27.2 versus 15.2; P < 0.0001) and greater percentage of the total sleep time below an oxygen saturation of 90% (7.2 versus 1.8; P < 0.0001). HD patients were more likely to have severe SDB (>30 respiratory events per hour) compared with the SHHS sample (odds ratio 4.07; 95% confidence interval 1.83 to 9.07). There was a strong association of HD with severe SDB and nocturnal hypoxemia independent of age, BMI, and the higher prevalence of chronic disease. The potential mechanisms for the higher likelihood of SDB in the HD population must be identified to provide specific prevention and therapy.

Abstract
PURPOSE Although sleep disturbances are common in epilepsy, few studies examined the prevalence and impact of sleep disturbance in epilepsy patients. This study investigates these in a cross-sectional survey. METHODS We surveyed 201 adult partial-onset epilepsy patients taking stable regimens of two or more antiepileptic medications. Community-based U.S. neurologists recorded patient demographic and clinical information. Patients completed the Medical Outcomes Study (MOS) Sleep Scale, the Quality of Life in Epilepsy-10 instrument (QOLIE-10), and the EuroQol-5D (EQ-5D). We evaluated the associations of sleep with health-related quality of life and clinical and demographic characteristics by using correlation coefficients and analysis of variance. RESULTS Mean (SD) age was 44.2 (12.5); 34% of patients had diagnosed sleep disturbances; 10% received prescription sleep medications. Patients with sleep disturbance reported poorer mean QOLIE-10 (55.2 vs. 63.7; p = 0.006) and EQ-5D (0.49 vs. 0.71; p < 0.001) scores relative to those without sleep disturbances. The mean (SD) MOS Sleep Problems Index score was 36.2 (20.8), worse than the general population mean of 26. Patients with physician-reported anxiety or depression had more sleep problems than did those without these comorbidities. Higher Sleep Problems Index scores were significantly (p < 0.001) correlated with poorer QOLIE-10 (r=-0.49) and EQ-5D (r=-0.56) scores. Patients experiencing a seizure within the past week reported higher MOS Sleep Problems Index scores than did those with a less-recent seizure (41.5 vs. 32.8; p = 0.003). CONCLUSIONS Diagnosed and self-reported sleep disturbances in patients with partial-onset epilepsy are frequently overlooked, but are negatively associated with everyday functioning and well-being, and therefore contribute significantly to the burden of epilepsy.

Abstract
Despite the fact that haemodialysis requires that spouses support and assist their partner during the treatment period, little attention has been focused on their health. The aim of this study was to explore experiences of health in everyday life among spouses of haemodialysis patients. The study had an explorative and descriptive design based on content analysis. Thirteen participants were interviewed in their home without the presence of the patient. The results show that arduousness was experienced when that spouses' everyday life was taken up by caring for the patient at the expense of his/her own health. Spouses exhibited stamina and neglected their own health when focusing on the patient and minimising their own condition. Independence in everyday life revealed that spouses who cared about themselves and looked after their own health experienced relaxation and happiness, which protected their health. Clinical interventions should include an assessment of the spouses' health and everyday life in order to plan the care to ensure that it is directed towards increasing their independence. Instruments need to be developed that assess when and how spouses experience the greatest sense of well-being, if they have scope for relaxation and recovery, and what type of support they require in their everyday life.

Abstract
BACKGROUND AND PURPOSE This study explored the distribution of Epworth Sleepiness Scale (ESS) scores in a randomly sampled, community population and provided percentile scores that will assist in decision-making in both research and clinical settings. PATIENTS AND METHODS Participants included 703 individuals between the ages of 20 and 98, with 116 people with insomnia (PWI) and 587 people not having insomnia (PNI). Analyses produced main effects for sleep status and ethnicity. RESULTS PWI had higher ESS scores than PNI and African-Americans had higher ESS scores than Caucasians, although effect sizes were small. Gender, age group, and season did not impact ESS scores. Receiver operating characteristic (ROC) curve analysis proved the ESS to discriminate poorly between PWI and PNI. CONCLUSIONS This study found higher percentages of 'sleepy' individuals than previous studies. PWI did have slightly elevated scores on the ESS, but this elevation was not necessarily predictive of an insomnia diagnosis. Results support a continuum of sleepiness/alertness among PWI.
