UNLABELLED BACKGROUND AND OBJECTVE: Chronic inflammatory diseases have been investigated as a possible source of inflammation in chronic kidney disease patients; however, there is a shortage of information about the prevalence of periodontitis in such individuals. Therefore, the aim of this cross-sectional study was to determine the extent and severity of(More)
This study sought for evidence of previous CMV infection in patients of a general hospital serving the low income population of Rio de Janeiro. An enzyme immunoassay was used to detect anti-CMV antibodies in 713 typical hospital patients classified into eight different groups. Positive tests were found in 87% of pregnant women, 85% of newborns, 61% of(More)
BACKGROUND AND OBJECTIVES The control of hyperphosphatemia is an unmet need in dialysis care. Compared to conventional hemodialysis (cHD), extended hemodialysis (eHD) appears to more easily control blood phosphate levels in chronically dialyzed patients. Here, we sought to compare eKT/V-matched cHD and eHD procedures in order to quantify the contribution of(More)
This work deals with the use of multiple correspondence analysis (MCA) and a weighted Euclidean distance (the tolerance distance) as an exploratory tool in developing predictive logistic models. The method was applied to a living-donor kidney transplant data set with 109 cases and 13 predictors. This approach, followed by backward and forward selection(More)
With the introduction of combined active antiretroviral therapy and the improved survival of HIV-infected patients, degenerative diseases and drug toxicity have emerged as long-term concerns. We studied the prevalence of decreased glomerular filtration rate (GFR) and associated risk factors in a cohort of HIV-infected patients from a middle-income country.(More)
This work introduces a heuristic index (the "tolerance distance") to define the "closeness" of two variable categories in multiple correspondence analysis (MCA). This index is a weighted Euclidean distance where weightings are based on the "importance" of each MCA axis, and variable categories were considered to be associated when their distances were below(More)
BACKGROUND The resistive index (RI) is used to evaluate renal allograft perfusion and dysfunction. Whereas the RI prognostic role for graft function has received considerable attention, less attention was paid to potential determinants of RI. The aim of this study was to present the results of interlobar artery RI, with special attention given to variables(More)
