BACKGROUND The prevalence of chronic kidney disease (CKD) is increasing in the United States, caused in part by older age and increasing prevalences of hypertension and type 2 diabetes. CKD is silent and undetected until advanced stages. The study of populations with earlier stages of kidney disease may improve outcomes of CKD. METHODS The Kidney Early(More)
BACKGROUND Diabetes contributes to increased morbidity and mortality in patients with chronic kidney disease (CKD). We sought to describe CKD awareness and identify factors associated with optimal glycemic control in diabetic and nondiabetic individuals both aware and unaware of CKD. METHODS This cross-sectional analysis compared Kidney Early Evaluation(More)
BACKGROUND Chronic kidney disease (CKD) recently was identified as a public health problem requiring a public health prevention approach. The National Kidney Foundation Kidney Early Evaluation Program (KEEP), initiated in 2000, meets the definition of a public health program, offering surveillance and early detection of CKD. This report aims to detail(More)
BACKGROUND The prevalence and incidence of hypertension are increasing, and they correlate with the chronic kidney disease rate in the United States. Early identification and achievement of blood pressure goals may improve chronic kidney disease outcomes. METHODS In this cross-sectional study, subjects were participants in the Kidney Early Evaluation(More)
BACKGROUND Diabetes mellitus is the leading cause of chronic kidney disease (CKD) and contributes to increased morbidity and mortality in the CKD population. Early diabetes identification through targeted screening programs is important for the development of preventive strategies. METHODS This is a cross-sectional analysis of the National Kidney(More)
BACKGROUND Chronic kidney disease (CKD) is a worldwide public health problem. Systolic blood pressure as an associated feature of CKD has not been fully explored in community volunteer and nationally representative samples of the US population. METHODS This cross-sectional analysis evaluated hypertension and early-stage CKD in participants in the Kidney(More)
Host-plant resistance is the most practical and economical approach to control the rice planthoppers. However, up to date, few rice germplasm accessions that are resistant to the all three kinds of planthoppers (1) brown planthopper (BPH; Nilaparvata lugens Stål), (2) the small brown planthopper (SBPH; Laodelphax striatellus Fallen), and (3) the whitebacked(More)
As a facile method to prepare hydrophilic polymeric microspheres, reflux precipitation polymerization has been widely used for preparation of polymer nanogels. In this article, we synthesized a phthalamide-protected N-aminooxy methyl acrylamide (NAMAm-p) for preparation of alkoxyamine-functionalized polymer composite microspheres via reflux precipitation(More)
By considering a constraint on the energy profile, a new implicit approach is developed to solve nonlinear eigensolution problems. A corresponding minimax method is modified to numerically find eigensolutions in the order of their eigenvalues to a class of semilinear elliptic eigensolution problems from nonlinear optics and other nonlinear(More)
