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)
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 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)
BACKGROUND AND OBJECTIVES The present study aimed to evaluate the prognostic impact of predialysis dysnatremia in patients with acute kidney injury requiring renal replacement therapy (RRT). DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS A secondary analysis of a prospective multicenter cohort study was performed. Serum sodium (Na) concentrations were(More)
A growing fraction of the clinical duties of Nephrologists is undertaken inside intensive care units. While assessing patients with acute renal failure in the context of circulatory collapse, which are also edematous and/or with impaired gas exchanges, the Nephrologist must decide between two opposing therapies: 1) remove volume with the aid of dialysis or(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)
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)
