Sensitivity, specificity and comparison of three commercially available immunological tests in the diagnosis of Cryptosporidium species in animals

Braz. j. microbiol; 49 (1), 2018
ABSTRACT The study was conducted to compare the specificity of immunological diagnostic methods used for the diagnosis of Cryptosporidium species capable of causing life-threatening infection in both immunosuppressed and immunocompetent patients. For the detection of Cryptosporidium species in 79 animals...

Yersinia pestis detection by loop-mediated isothermal amplification combined with magnetic bead capture of DNA

Braz. j. microbiol; 49 (1), 2018
ABSTRACT We developed a loop-mediated isothermal amplification (LAMP) assay for the detection of Y. pestis by targeting the 3a sequence on chromosome. All 11 species of the genus Yersinia were used to evaluate the specificity of LAMP and PCR, demonstrating that the primers had a high level of specificity...

Rev. méd. Chile; 146 (3), 2018
Background: The Woman Abuse Screening Tool (WAST) is a screening tool for domestic violence used in Unites States. Aim: To carry out the cultural adaptation of the WAST instrument for early detection of domestic violence in primary health care. Material and Methods: Qualitative techniques for cultural ...

Bioimpedância: nova abordagem para detecção não invasiva da fibrose hepática - estudo piloto

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Fibrosis are common structural hepatic change in patients with chronic hepatitis. Liver biopsy is the gold standard for determining the extent of liver fibrosis. Considering the technical difficulties and cost, improvements in non-invasive screening tools are greatly needed. Bioimpe...

Potential application of rLc36 protein for diagnosis of canine visceral leishmaniasis

Mem. Inst. Oswaldo Cruz; 113 (3), 2018
Visceral leishmaniasis (VL) is fatal if left untreated. Infected dogs are important reservoirs of the disease, and thus specific identification of infected animals is very important. Several diagnostic tests have been developed for canine VL (CVL); however, these tests show varied specificity and sensiti...

Natriuretic Peptide and Clinical Evaluation in the Diagnosis of Heart Failure Hemodynamic Profile: Comparison with Tissue Doppler Echocardiography

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Physical examination and B-type natriuretic peptide (BNP) have been used to estimate hemodynamics and tailor therapy of acute decompensated heart failure (ADHF) patients. However, correlation between these parameters and left ventricular filling pressures is controversial. Objectiv...

Utilização dos níveis de amilase no dreno abdominal para diagnóstico de fístulas anastomóticas após o bypass gástrico em Y de Roux

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Although the incidence of leaks after Roux-en-Y gastric bypass (RYGB) significantly decreased over time, their detection still remains challenging. OBJECTIVE: This study aimed to determine the usefulness of drain amylase levels to detect leaks after RYGB. METHODS: This is a pop...

Detection of toxigenic Clostridioides --#1;Clostridium--#3; difficile: Usefulness of two commercially available enzyme immunoassays and a PCR assay on stool samples and stool isolates

Rev. argent. microbiol; 50 (1), 2018
The best laboratory diagnostic approach to detect Clostridioides --#1;Clostridium--#3; difficile infection (CDI) is a subject of ongoing debate. With the aim of evaluating four laboratory diagnostic methods, 250 unformed stools from patients with suspected CDI submitted to nine medical center laboratorie...

Reliability of Thyroid Imaging Reporting and Data System (TI-RADS), and ultrasonographic classification of the American Thyroid Association (ATA) in differentiating benign from malignant thyroid nodules

ABSTRACT Objective Ultrasonography (US) is the best diagnostic tool for initial assessment of thyroid nodule. Recently, data reporting systems for thyroid lesions, such as the Thyroid Imaging Reporting and Data System (TI-RADS) and American Thyroid Association (ATA), which stratifies the risk for malign...

Diagnostic utility of DREAM gene mRNA levels in thyroid tumours

ABSTRACT Objective The transcriptional repressor DREAM is involved in thyroid-specific gene expression, thyroid enlargement and nodular development, but its clinical utility is still uncertain. In this study we aimed to investigate whether DREAM mRNA levels differ in different thyroid tumors and how thi...
