BACKGROUND As several studies have shown an association between periodontal disease and chronic kidney disease (CKD), regular dental care may be an important strategy for reducing the burden of CKD. Access to dental care may be limited in the US public health system. METHODS In this retrospective cohort study of 6,498 adult patients with (n = 2,235) and(More)
BACKGROUND It is unknown whether the selection of healthier patients for arteriovenous fistula (AVF) placement explains higher observed catheter-associated mortality among elderly hemodialysis patients. METHODS From the United States Renal Data System 2005-2007, we used proportional hazard models to examine 117 277 incident hemodialysis patients aged(More)
BACKGROUND Early preparation for renal replacement therapy (RRT) is recommended for patients with advanced chronic kidney disease (CKD), yet many patients initiate RRT urgently and/or are inadequately prepared. METHODS We conducted audio-recorded, qualitative, directed telephone interviews of nephrology health care providers (n = 10, nephrologists,(More)
Whether kidney dysfunction is associated with coronary artery calcium (CAC) in young and middle-aged adults who have a cystatin C–derived estimated glomerular filtration rate (eGFRcys) greater than 60 mL/min/1.73 m 2 is unknown., we examined 1) the association of eGFRcys at years 10 and 15 and detectable CAC over the subsequent 5 years and 2) the(More)
BACKGROUND In December 2000, Medicare eliminated time limitations in immunosuppressant coverage after kidney transplant for beneficiaries age ≥65 and those who were disabled. This change did not apply to younger non-disabled beneficiaries who qualified for Medicare only because of their end-stage renal disease (ESRD). We sought to examine access to(More)
BACKGROUND Illicit drug use is common and known to cause and exacerbate a wide spectrum of kidney disease, often leading to end-stage renal disease (ESRD), but little is known about its prevalence or associated mortality among incident hemodialysis patients. METHODS This study is a retrospective cohort analysis using data obtained from the United States(More)
OBJECTIVE Many societies recommend using estimated glomerular filtration rate (eGFR) rather than serum creatinine (sCr) to determine metformin eligibility. We examined the potential impact of these recommendations on metformin eligibility among U.S. adults. RESEARCH DESIGN AND METHODS Metformin eligibility was assessed among 3,902 adults with diabetes who(More)
BACKGROUND The prevalence in the United States of dietary supplement use that may be harmful to those with chronic kidney disease (CKD) is unknown. We sought to characterize potentially harmful supplement use by individual CKD status. STUDY DESIGN Cross-sectional national survey (National Health and Nutrition Examination Survey, 1999-2008).
