Vitamin D receptor activation is associated with improved survival in patients with chronic kidney disease, but the mechanism of this benefit is unclear. To better understand the effects of vitamin D on endothelial function, blood pressure, albuminuria, and inflammation in patients with chronic kidney disease (2 patients stage 2, remaining stage 3), we(More)
Blood pressure (BP) recordings often differ between arms, but the extent to which these differences are reproducible and whether the differences have prognostic importance is unknown. We enrolled 421 consecutive patients from a medicine and a renal clinic at a veterans' hospital. Three BP recordings were obtained in each arm using an oscillometric device in(More)
BACKGROUND Death and dialysis are competing outcomes in patients with chronic kidney disease (CKD). The factors associated with end-stage renal disease (ESRD) versus death in this population are unknown. The purpose of our study was to evaluate the competing risk of ESRD versus mortality and to evaluate the risk factors associated with these two outcomes.(More)
BACKGROUND AND OBJECTIVES The diagnosis of hypertension among hemodialysis patients by predialysis or postdialysis blood pressure (BP) recordings is imprecise and biased and has poor test-retest reliability. The use of intradialytic BP measurements to diagnose hypertension is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A diagnostic-test study(More)
BACKGROUND Although the optimum hemoglobin (H) concentration for patients with septic shock (SS) has not been specifically investigated, current guidelines suggest that H of 7 - 9 g/dL, compared with 10 - 12 g/dL, was not associated with increased mortality in critically ill adults. This contrasts with early goal-directed resuscitation protocols that use a(More)
