Effect of intradialytic weight resistance training exercise in sarcopenic hemodialysis patients: A randomized controlled trial.

Background: Sarcopenia has a high prevalence in end-stage kidney disease (ESKD). However, there is limited evidence of resistance exercise in these patients.

Objective: The study investigated the effects of resistance exercise on muscle mass, strength, and physical functioning.

QEEG characteristics associated with malnutrition-inflammation complex syndrome.

End-stage renal disease (ESRD) has been linked to cerebral complications due to the comorbidity of malnutrition and inflammation, which is referred to as malnutrition-inflammation complex syndrome (MICS). The severity of this condition is clinically assessed with the malnutrition-inflammation score (MIS), and a cutoff of five is used to optimally distinguish patients with and without MICS. However, this tool is still invasive and inconvenient, because it combines medical records, physical examination, and laboratory results.

EEG Delta/Theta Ratio and Microstate Analysis Originating Novel Biomarkers for Malnutrition-Inflammation Complex Syndrome in ESRD Patients.

The Malnutrition-Inflammation Score (MIS) was initially proposed to evaluate malnutrition-inflammation complex syndrome (MICS) in end-stage renal disease (ESRD) patients. Although MICS should be routinely evaluated to reduce the hospitalization and mortality rate of ESRD patients, the inconvenience of the MIS might limit its use. Cerebral complications in ESRD, possibly induced by MICS, were previously assessed by using spectral electroencephalography (EEG) via the delta/theta ratio and microstate analysis.

Background Activity Findings in End-Stage Renal Disease With and Without Comorbid Diabetes: An Electroencephalogram Study.

Renal failure and diabetes can induce cerebral complications, including encephalopathy, for which attentional and cognitive impairment are common symptoms. It is possible that renal failure with comorbid diabetes may induce more severe encephalopathy due to multiple pathogenic mechanisms. This concept was supported by the main findings of this study, which showed that EEG background activity between end-stage renal disease with and without comorbid diabetes was significantly different in relative power of delta in the eyes-open condition in frontoparietal regions; theta in the eyes-closed condition in all regions; beta in the parieto-occipital regions in both eye conditions; the delta/theta ratio in both eye conditions in frontoparietal regions; and the theta/beta ratio in all regions in the eyes-closed condition.

Effectiveness of renal-specific oral nutritional supplements compared with diet counseling in malnourished hemodialysis patients.

Background: Malnutrition is highly prevalent and a consequence of inflammation and related comorbidities among patients on maintenance hemodialysis. Oral nutritional supplementation (ONS) is recommended for malnourished patients with kidney failure. The study aimed to evaluate renal-specific oral nutrition (ONCE dialyze) supplement on nutritional status in patients on hemodialysis.

Efficacy of High vs. Conventional Ergocalciferol Dose for Increasing 25-Hydroxyvitamin D and Suppressing Parathyroid Hormone Levels in Stage III-IV CKD with Vitamin D Deficiency/Insufficiency: A Randomized Controlled Trial.

Background: Vitamin D deficiency/insufficiency is common in chronic kidney disease (CKD) patients and it contributes to secondary hyperparathyroidism, which occurs early in CKD. It is not clear whether the Kidney Disease Outcomes Quality Initiative (K/DOQI) recommended doses of ergocalciferol are adequate for correction of vitamin D insufficiency and hyperparathyroidism.

Objective: To evaluate the parathyroid hormone (PTH)-lowering effect, safety, and tolerability of high-dose ergocalciferol compared with conventional-dose ergocalciferol in CKD subjects.
