Materials and Methods
We enrolled 67 patients (age, 47.7 ± 11.4 years [mean ± SD]; 34 men, 33 women; duration of HD, 103.7 ± 59.1 months [mean ± SD]) who were on chronic maintenance HD at Baskent University Hospital (Ankara, Turkey). All patients had negligible residual renal function, and had been undergoing dialysis with a biocompatible membrane such as hemophane or polysulfone three times each week, 4 hr each time, and had been doing so for at least 12 months. We excluded patients who did not fill out
Results
Table 1 shows the demographic, clinical, and laboratory data of the 67 HD patients. Men comprised 51% of the study population. The mean MIS score was 7.7 ± 3.0 (range, 3-16).
The PSQI score ranged from 1 to 12, and 30 patients (42.5%) were poor sleepers (PSQI >5). We divided patients into two groups according to PSQI score: good sleepers (PSQI ≤5) and poor sleepers (PSQI >5). Table 2 shows the characteristics of each group. Compared with good sleepers, poor sleepers had lower serum albumin (38.0
Discussion
In our patients, the mean MIS value was 7.7 ± 3.0, and our results show that higher MIS values were associated with the presence of moderate-to-severe depression, poor quality of sleep, and poor quality of life.
In our study, the prevalence of poor sleep quality was 42.5%, comparable with the 45% to 80% prevalence of sleep complaints in HD patients reported in previous studies.7, 12, 30 Numerous factors probably contribute to the high prevalence of sleep problems in HD patients, including

Differences and Effects of Metabolic Fate of Individual Amino Acid Loss in High-Efficiency Hemodialysis and Hemodiafiltration
2020, Journal of Renal NutritionCitation Excerpt :This study shows how at the time of recruitment patients were already affected by a state of malnutrition/inflammation typical of the terminal stages of uremia in patients on dialysis.38 Indeed, this serious metabolic situation represents a key component of the so-called “malnutrition-inflammatory complex syndrome”39,40 linked in patients on dialysis to a reduced quality of life, increased number of hospitalizations, higher incidence of coronary heart disease and depression, and an increased mortality rate.41-45 Malnutrition initially presents as a somatic protein type with the onset of sarcopenia.

Bilgic Akgul et al. were concluded sleep disorders are correlated with patients' nutritional status [16]. Foods containing tryptophan, serotonin and melatonin may have beneficial effects on the improving patients' sleep status [17,18].
