Background: Stroke is the third leading cause of cardiovascular mortality in dialysis patients. The objective of this study was to assess the extent of stroke in chronic hemodialysis patients.
Methods: Historical cohort of patients enrolled in two hemodialysis (HD) centers from January 1, 2010 to December 31, 2011, including 191 patients (mean age 52 years, 68% men). Incidence curves and survival time analysis between the first day of HD and the end of the study were described by the Kaplan-Meier method. Independent stroke predictors were identified by multiple logistic regression analysis. P < 0.05 defined the level of statistical significance.
Results: 12 incident stroke were recorded during the study period, with 1622.1 person-months (PM), a stroke incidence rate of 7.4 cases per 1000 PM (95% CI = 7.35-7.44) at the point date. The incidence of stroke at 6 months, 12 months and 24 months was 9.8%, 11.9% and 13%, respectively. Only the absence of arterial hypertension (RR = 5.7, 95% CI: 1.52-21.42) emerged as an independent determinant of stroke.
Conclusion: The high incidence of stroke in Kinshasa HD centers is partially explained by reverse epidemiology. Efforts must be made to understand this phenomenon in order to reduce its impact.

Introduction: A significant portion of posterior urethral valve patients continue to progress to end stage renal disease despite improvements in medical care. Socioeconomic status has been connected to various healthcare outcomes but has not been evaluated in relation to longitudinal outcomes of posterior urethral valves.
Objective: To evaluate the effect of socioeconomic status on the progression to renal failure among patients with posterior urethral valves.

Background: The net benefit of oral anticoagulation in patients with end-stage renal disease on hemodialysis (HD) is uncertain. In recent years, left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation; however, there is scant evidence of LAAC in patients on HD.
Objectives: This study aimed to assess the feasibility and safety of LAAC in patients on HD.

Background: Insulin resistance often occurs in patients with chronic kidney disease (CKD) owing to mineral and bone metabolism disorders. Fibroblast growth factor (FGF)-23 and soluble klotho (s-KL) play crucial roles in linking CKD with mineral and bone metabolism.
Objective: This study aimed to examine the relationship between insulin resistance and FGF-23 and s-KL in patients with non-diabetic pre-dialysis patients with CKD.

Despite the relevance of kidney transplantation, the supply of organs and the process for inclusion in its waiting list still represent obstacles. This study aimed to analyze the performance of dialysis centers in referring patients for pre-kidney transplant evaluation and inclusion in the waiting list of incident dialysis patients from 2015 to 2019 in the state of Minas Gerais, Brazil. This retrospective cohort study sampled 23,297 records of patients who underwent dialysis therapy in public or philanthropic institutions or who had their treatment funded by the Brazilian Unified National Health System in private clinics.
