this study was aimed to evaluate the efficacy of dipstick tests (leukocyte esterase and nitrite) in diagnosis of spontaneous bacterial peritonitis (sbp) in cirrhotic patients. forty six children with ascites hospitalized between 2009 and 2010 in children medical center were enrolled in this study. reagent strip assays for leukocyte esterase and nitrite were performed on ascetic fluid and the re...
Background Objective: To evaluate the utility of specific cut-off values for C- reactive protein (CRP) and immature-to-total neutrophil ratio (I/T) as screening tests for meningitis in culture negative early onset sepsis (EOS). Materials and Methods Retrospective chart review of 97 newborns with culture negative sepsis who had lumbar puncture performed as part of the sepsis evaluation in a l...

this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
Background: Considering the prevalence of brucellosis in Iran, it is necessary to choose a specific and sensitive laboratory method to diagnose it in a rapid and timely manner. The aim of this study was to assess the accuracy of indirect enzyme-linked immunosorbent assay (ELISA) for detecting brucellosis in humans in order to have an appropriate alternative to conventional tests such as Wright,...
Background: Disease prevalence is rarely explicitly considered in the early stages of the development of novel prognostic tests. Rather, researchers use the area under the receiver operating characteristic (AUROC) as the key metric to gauge and report predictive performance ability. Because this statistic does not account for disease prevalence, proposed tests may not appropriately address clin...
