Abstract
INTRODUCTION Fatigue is reportedly associated with a poor prognosis in dialysis patients. The aim of the present study was to investigate whether fatigue on dialysis days or non-dialysis days is associated with mortality in patients on chronic hemodialysis. METHODS This was a prospective study of 134 hemodialysis patients. The level of fatigue was evaluated using a visual analog scale (VAS). The association between high fatigue evaluated by the highest quartile of the VAS value and all-cause death was investigated. RESULTS The fatigue scale score was significantly higher on dialysis than on non-dialysis days. During the follow-up period (median 6.8 years), 42 patients died. Patients with high post-dialysis fatigue in the higher quartiles died more frequently compared to those with in the lower quartiles (p = 0.012). Multivariate Cox regression analysis showed that high post-dialysis fatigue was an independent predictor of all-cause death (adjusted hazard ratio 2.12, 95% confidence interval 1.10-4.07). CONCLUSION Higher post-dialysis fatigue is related to increased mortality.

Abstract
Hydrogen-rich water (HRW) has emerged as a novel approach in the field of health and wellness. It is believed to have therapeutic antioxidant properties that can neutralize harmful free radicals in the human body. It has also been shown to be beneficial in mitigating oxidative stress-induced damage through its anti-inflammatory and anti-apoptotic pathways. We aim to conduct a systematic review to evaluate the potential benefits of hydrogen-rich water. The review protocol was uploaded on PROSPERO. After the initial search criteria, the articles were reviewed by two blinded investigators, and a total of 25 articles were included in the systematic review. The potential benefits of hydrogen-rich water on various aspects of health, including exercise capacity, physical endurance, liver function, cardiovascular disease, mental health, COVID-19, oxidative stress, and anti-aging research, are a subject of growing interest and ongoing research. Although preliminary results in clinical trials and studies are encouraging, further research with larger sample sizes and rigorous methodologies is needed to substantiate these findings. Current research needs to fully explain the mechanisms behind the potential benefits of hydrogen-rich water. Continued scientific exploration will provide valuable insights into the potential of hydrogen-rich water as an adjunctive therapeutic approach in the future.

Abstract
Chronic kidney disease (CKD), which is globally on the rise, has become an urgent challenge from the perspective of public health, given its risk factors such as end-stage renal failure, cardiovascular diseases, and infections. The pathophysiology of CKD, including dialysis patients, is deeply associated with enhanced oxidative stress in both the kidneys and the entire body. Therefore, the introduction of a safe and widely applicable antioxidant therapy is expected as a measure against CKD. Electrolyzed hydrogen water (EHW) generated through the electrolysis of water has been confirmed to possess chemical antioxidant capabilities. In Japan, devices producing this water have become popular for household drinking water. In CKD model experiments conducted to date, drinking EHW has been shown to suppress the progression of kidney damage related to hypertension. Furthermore, clinical studies have reported that systemic oxidative stress in patients undergoing dialysis treatment using EHW is suppressed, leading to a reduction in the incidence of cardiovascular complications. In the future, considering EHW as one of the comprehensive measures against CKD holds significant importance. The medical utility of EHW is believed to be substantial, and further investigation is warranted.

Impact of hemodialysis solutions containing different levels of molecular hydrogen (H2) on the patient-reported outcome of fatigue. RENAL REPLACEMENT THERAPY 2022.

Abstract
Abstract
Background
Reportedly, dialysis solutions containing molecular hydrogen (H2) might ameliorate patient-reported fatigue in hemodialysis (HD) patients. However, it is unknown whether its impact might differ with different H2 levels.
Method
This single-arm, prospective observational study examined 105 patients on chronic HD (62 males; mean age, 66 years; mean HD duration, 117 months). All patients were originally treated with an HD solution with 47 ppb (mean) H2 for more than 12 months, followed by an HD solution with 154 ppb (mean) H2 for 8 weeks. Baseline and changes in subjective fatigue status rated on a numerical rating scale (NRS) were assessed before the start of the study (baseline) and 8th week of the study.
Results
Patients were classified into three groups according to the presence of subjective fatigue at baseline: Group A (15.2%), presence of fatigue on both HD and HD-free days; Group B (28.6%), fatigue only on HD days; and Group C (56.2%), freedom from fatigue. In Group A, NRS scores during the 8-week period were significantly decreased as compared with 0 week, at the 4th and 8th week on HD days, and at the 8th week on HD-free day, respectively. While no consistent changes were found in other groups. At the 8th week, 64 patients (61%) presented absence of or decrease in the NRS score of fatigue, while the rest of patients did not present the decrease in NRS (the non-improved: 39%). Regarding the factors related to the non-improved, prescription of antihypertensive agents was a significant independent risk factor by multivariate analysis, indicating the possible involvement of excess fall in blood pressure (BP) in those patients.
Conclusion
Amelioration of the patient-reported outcome of fatigue might be influenced by H2 levels in the HD solution, and the optimal H2 level in the dialysate needs to be elucidated in consideration of clinical type of fatigue and BP control status.
