BACKGROUND Serum potassium levels affect insulin secretion by pancreatic β-cells, and hypokalemia associated with diuretic use has been associated with dysglycemia. We hypothesized that adults with lower serum potassium levels and lower dietary potassium intake are at higher risk for incident diabetes mellitus (DM), independent of diuretic use. METHODS We(More)

BACKGROUND Several observational studies have evaluated the effect of a single exposure window with blood pressure (BP) medications on outcomes in incident dialysis patients, but whether BP medication prescription patterns remain stable or a single exposure window design is adequate to evaluate effect on outcomes is unclear. METHODS We described patterns(More)
BACKGROUND Abnormalities in mineral homeostasis are ubiquitous in patients on dialysis, and influenced by race. In this study, we determine the race-specific relationship between mineral parameters and mortality in patients initiating hemodialysis. METHODS We measured the levels of fibroblast growth factor 23 (FGF23) and 25-hydroxyvitamin D (25 D) in 184(More)
Thiazides, recommended as first-line antihypertensive therapy, are associated with an increased risk of diabetes. Thiazides also lower serum potassium. To determine whether thiazide-induced diabetes is mediated by changes in potassium, we analyzed data from 3790 nondiabetic participants in the Systolic Hypertension in Elderly Program, a randomized clinical(More)
AIMS/HYPOTHESIS High-dose supplements of thiamine prevent the development of microalbuminuria in experimental diabetes. The aim of this pilot study was to assess whether oral supplements of thiamine could reverse microalbuminuria in patients with type 2 diabetes. METHODS Type 2 diabetic patients (21 male, 19 female) with microalbuminuria were recruited at(More)
BACKGROUND Cystatin C level predicts mortality more strongly than serum creatinine level. It is unknown whether this advantage extends to other outcomes, such as kidney failure, or whether other novel renal filtration markers share this advantage in predicting outcomes. STUDY DESIGN Observational cohort study. SETTING & PARTICIPANTS 9,988 participants(More)
Studies of dialysis initiation timing have not accounted for predialysis clinical factors that could impact postdialysis outcomes. We examined the association of predialysis health with timing of dialysis initiation in older adult patients in the United States and contrasted morbidity and mortality outcomes among patients with early [estimated GFR (eGFR)≥10(More)
Conventional allogeneic stem cell transplantation (SCT) for myelodysplastic syndrome (MDS) is associated with excessive procedure-related mortality. The outcome following volunteer-unrelated donor (VUD) or sibling allogeneic SCT was therefore evaluated in 23 MDS patients conditioned with reduced-intensity regimens (fludarabine/busulphan/Campath-1H) because(More)
BACKGROUND Residual kidney function (RKF) is associated with improved survival in peritoneal dialysis patients, but its role in hemodialysis patients is less well known. Urine output may provide an estimate of RKF. The aim of our study is to determine the association of urine output with mortality, quality of life (QOL), and inflammation in incident(More)
BACKGROUND The Chronic Kidney Disease Epidemiology Collaboration equation for estimation of glomerular filtration rate (eGFR(CKD-EPI)) improves GFR estimation compared with the Modification of Diet in Renal Disease Study equation (eGFR(MDRD)) but its association with mortality in a nationally representative population sample in the US has not been studied.(More)
