OBJECTIVES This study was designed to determine the effectiveness of a protocol for rapid intravenous hydration to prevent contrast-induced nephropathy (CIN) in patients undergoing emergency percutaneous coronary intervention (PCI). BACKGROUND Contrast-induced nephropathy frequently complicates PCI, resulting in prolonged hospitalization and increased(More)
BACKGROUND Cardiovascular (CV) events are common in patients with chronic kidney disease (CKD) but inadequately explained by traditional risk factors. Vitamin D deficiency is highly prevalent in CKD and has been proposed to be a non-traditional risk factor, but its relationship with vascular function is unknown. METHODS AND RESULTS The aim of this study(More)
Mouse models of human cancers afford unique opportunities to evaluate novel therapies in preclinical trials. For this purpose, we analyzed three genetically engineered mouse (GEM) models of low-grade glioma resulting from either inactivation of the neurofibromatosis-1 (Nf1) tumor suppressor gene or constitutive activation of KRas in glial cells. Based on(More)
Individuals with neurofibromatosis type 1 (NF1) are prone to develop optic pathway gliomas that can result in significant visual impairment. To explore the cellular basis for the reduced visual function resulting from optic glioma formation, we used a genetically engineered mouse model of Nf1 optic glioma (Nf1+/-(GFAP)CKO mice). We performed multimodal(More)
BACKGROUND Cardiovascular events are frequent and vascular endothelial function is abnormal in patients with chronic kidney disease (CKD). We demonstrated endothelial dysfunction with vitamin D deficiency in CKD patients; however the impact of cholecalciferol supplementation on vascular stiffness and vasomotor function, endothelial and bone biomarkers in(More)
BACKGROUND Cardiovascular morbidity and mortality are high in chronic kidney disease (CKD) patients compared to the general population. Systemic inflammation may contribute to endothelial dysfunction and accelerated atherosclerosis in CKD patients. We assessed the relationship among, endothelial dysfunction, early atherosclerosis and inflammation in(More)
BACKGROUND Human immunodeficiency virus (HIV)-associated nephropathy (HIVAN) is an important cause of end-stage renal disease among African American patients. This study was performed to study the epidemiology of HIVAN in a predominantly black African population and the impact of highly active antiretroviral therapy and other factors on the development of(More)
AIM Cardiovascular complications are common in patients with chronic kidney disease in the general population. The study aims to investigate the prevalence and prognosis of CKD stages 3-5 in the veterans affairs (VA) population, which is sicker with more co-morbid conditions. METHODS In this case-controlled study of 6,432 men the associations of risk(More)
Cardiovascular disease poses the greatest risk of premature death seen among patients with chronic kidney disease (CKD). Up to 50% of mortality risk in the dialysis population is attributable to cardiovascular disease and the largest relative excess mortality is observed in younger patients. In early CKD, occlusive thrombotic coronary disease is common, but(More)
