Pre-Infection Nutritional Status, Oxidative Stress, and One-Year-Long COVID Persistence in Patients Undergoing Hemodialysis: A Prospective Cohort Study.

Background: Nutritional status's role in long COVID is evident in the general population, yet unexplored in patients undergoing hemodialysis (HD), posing a research gap. We hypothesized that pre-infection undernutrition in HD patients might impact long COVID persistence by accelerating oxidative stress. The present study aimed to investigate the association between pre-infection nutritional status, oxidative stress, and one-year-long COVID persistence in HD patients.

Current therapeutic options for the treatment of secondary hyperparathyroidism in end-stage renal disease patients treated with hemodialysis: a 12-month comparative study.

Aim: The aim of the study was to investigate the effect of a new calcimimetic, Etelcalcetide, on secondary hyperparathyroidism and its effects in end-stage renal disease (ESRD) patients treated with hemodialysis (HD) compared with hemodialysis (HD) patients not treated with calcimimetics.

Materials And Methods: The cohort study included 203 ESRD patients with secondary hyperparathyroidism (SHPT) who received HD treatment. Total number patients were randomly to two groups.
