(2-Heremans-schmid glycoprotein (fetuin A) downregulation and its utility in inflammatory bowel disease
(2017)AIM: To investigate the impact of inflammatory bowel disease (IBD) on α2-Heremans-Schmid Glycoprotein (AHSG/fetuin A) and potential associations with disease and patient characteristics. METHODS: AHSG serum levels were ... -
Abdominal Aortic Aneurysm Screening: Do We Need to Shift Toward a Targeted Strategy?
(2018)[No abstract available] -
Acute phase markers for the differentiation of infectious and malignant pleural effusions
(2007)Acute-phase markers, such as C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α), have been studied in inflammatory and malignant disorders. We examined the diagnostic value of these ... -
Anatomical Differences Between Intact and Ruptured Large Abdominal Aortic Aneurysms
(2020)Purpose: To compare different anatomical characteristics between intact and ruptured large abdominal aortic aneurysms (rAAA >80 mm) with the goal of refining the process of estimating rupture risk. Materials and Methods: ... -
Anti-MCV antibodies predict radiographic progression in Greek patients with very early (<3 months duration) rheumatoid arthritis
(2017)This study aimed to assess the diagnostic and prognostic value of anti-mutated citrullinated vimentin (MCV) antibodies in very early rheumatoid arthritis (VERA) and in established rheumatoid arthritis (RA). Seventy-one ... -
Antibody tests in detecting SARS-CoV-2 infection: A meta-analysis
(2020)The emergence of Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 made imperative the need for diagnostic tests that can identify the infection. Although Nucleic Acid Test (NAT) is considered to be the gold standard, ... -
Application of a semi-dependent latent model in the Bayesian estimation of the sensitivity and specificity of two faecal culture methods for diagnosis of paratuberculosis in sub-clinically infected Greek dairy sheep and goats
(2006)In this study, we compared the frequency of isolation of Mycobacterium avium subsp. paratuberculosis (MAP) from faecal samples grown on Herrold's egg-yolk medium (HEYM) or on Lowenstein-Jensen (LJ) medium and estimated the ... -
Application of Bayesian modeling for diagnostic assays of Mycobacterium avium subsp. paratuberculosis in sheep and goats flocks
(2022)Background: This study aimed to screen the sera of goats and sheep from flocks suspected of Mycobacterium avium subsp. paratuberculosis (MAP) infection by a newly standardized Mce-truncated ELISA (Mt-ELISA) kit for the ... -
The association between retinopathy of prematurity and ocular growth
(2019)PURPOSE. The purpose of this study was to prospectively investigate the association between retinopathy of prematurity (ROP) and ocular growth in premature infants during the earliest weeks of life. METHODS. Premature ... -
Association of neutrophil–lymphocyte and platelet–lymphocyte ratio with adverse events in endovascular repair for abdominal aortic aneurysm
(2021)The association of chronic inflammatory markers with the clinical outcome after endovas-cular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) was investigated. We in-cluded 230 patients, treated electively with ... -
Association of serum calprotectin (S100A8/A9) concentrations and idiopathic hyperlipidemia in Miniature Schnauzers
(2019)Background: Idiopathic hyperlipidemia (IH) is a common condition in Miniature Schnauzers (MS). Studies in people have linked IH to low-grade inflammation, which plays an important role in the pathogenesis of IH complications. ... -
Bayesian estimation of sensitivity and specificity of a commercial serum/milk ELISA against the Mycobacterium avium subsp. Paratuberculosis (MAP) antibody response for each lactation stage in Greek dairy sheep
(2016)A total of 854 paired milk and blood samples were collected from ewes of a Greek flock and used to estimate the sensitivity and specificity of a commercial ELISA for detection of Mycobacterium avium subsp. paratuberculosis ... -
Bayesian estimation of sensitivity and specificity of a PCR method to detect Coxiella burnetii in milk and vaginal secretions in sheep and goat samples
(2019)Coxiella burnetii is a gram-negative and polymorphic rod bacterium that causes Q fever, a common zoonotic disease distributed worldwide. Widespread occurrences of the disease outbreaks indicate the importance of coordinated ... -
Bayesian Evaluation of Three Serological Tests for Diagnosis of Brucella infections in Dromedary Camels Using Latent Class Models
(2022)Brucellosis is a zoonotic disease with significant economic and public health impacts. The disease has been found in ruminants, including camels, but clinical diagnosis of camel brucellosis is difficult due to the lack of ... -
Bayesian evaluation of three serological tests for the diagnosis of bovine brucellosis in bangladesh
(2019)We evaluated the performance of three serological tests – an immunoglobulin G indirect enzyme linked immunosorbent assay (iELISA), a Rose Bengal test and a slow agglutination test (SAT) – for the diagnosis of bovine ... -
Bayesian latent class analysis when the reference test is imperfect [Analyse bayésienne à classes latentes dans les situations où le test de référence est imparfait] [Análisis bayesiano de clases latentes cuando la prueba de referencia es imperfecta]
(2021)Latent class analysis (LCA) has allowed epidemiologists to overcome the practical constraints faced by traditional diagnostic test evaluation methods, which require both a gold standard diagnostic test and ample numbers ... -
