Development and validation of a modified TaqMan based real-time PCR assay targeting the lipl32 gene for detection of pathogenic Leptospira in canine urine samples

Braz. j. microbiol; 49 (3), 2018
Abstract A modified TaqMan real-time polymerase chain reaction targeting a 138 bp fragment within the lipl32 gene was developed to identify exclusively pathogenic Leptospira spp. in dog urine samples. Thirty-five samples from dogs with suspected clinical leptospirosis and 116 samples from apparently heal...

Glutamato deshidrogenasa: Su valor diagnóstico en la diarrea por Clostridioides difficile

Rev. argent. microbiol; 50 (3), 2018
Clostridioides difficile es el principal agente causal de diarreas asociadas al cuidado de la salud. Esta bacteria produce toxinas y una enzima que se encuentra muy conservada en la especie: la glutamato deshidrogenasa (GDH). El diagnóstico rápido y el tratamiento efectivo permiten la pronta mejoría d...

Arch. cardiol. Méx; 88 (3), 2018
Resumen Objetivos: Determinar el rendimiento pronóstico con sensibilidad, especificidad, valor predictivo positivo y valor predictivo negativo del puntaje de riesgo en síncope OESIL para la predicción de eventos graves (mortalidad, intervenciones invasivas cardiovasculares y reingresos) a 6 meses en...

Diagnosing dementia in lower educated older persons: validation of a Brazilian Portuguese version of the Rowland Universal Dementia Assessment Scale (RUDAS)

Rev. bras. psiquiatr; 40 (3), 2018
Objective: To validate the Rowland Universal Dementia Assessment Scale for use in Brazil (RUDAS-BR). Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the RUDAS. A total of 135 subjects over 60 years of age were included: 65 cognitively healthy and 70 with A...

Comparison of five methods of extraction of Staphylococcus aureus DNA for molecular detection by PCR

Abstract INTRODUCTION Molecular techniques for the detection of pathogens have been shown to be effective diagnostic tools with high sensitivity and short turnaround times. METHODS This study compared five Staphylococcus aureus DNA extraction methods for detection by the polymerase chain reaction. R...

Comparison of inflammatory markers between brucella and non-brucella epididymo-orchitis

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Objectives: Brucellosis is a multi-system infectious disease that is associated with inflammation, which causes an increase in acute phase reactants. Hematological inflammatory markers of brucellosis include mean platelet volume (MPV), red cell distribution width (RDW), neutrophil/lymphocyte ra...

Diagnostic accuracy of multiparametric magnetic resonance imaging in detecting extracapsular extension in intermediate and high - risk prostate cancer

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Objectives: To evaluate the diagnostic performance of preoperative multiparametric magnetic resonance imaging (mp-MRI) as a predictor of extracapsular extension (ECE) and unfavorable Gleason score (GS) in patients with intermediate and high-risk prostate cancer (PCa). Materials and Methods: Pa...

Impact of PSA density of transition zone as a potential parameter in reducing the number of unnecessary prostate biopsies in patients with PSA levels between 2. 6 and 10. 0 ng/mL

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Purpose: To assess the accuracy of prostate-specific antigen (PSA) adjusted for the transition zone volume (PSATZ) in predicting prostate cancer by comparing the ability of several PSA parameters in predicting prostate cancer in men with intermediate PSA levels of 2.6 - 10.0 ng/mL and its abili...
