OBJECTIVE To analyse whether levels of high-sensitivity cardiac troponin (hs-cTn) below their respective 99th percentile can be used as a single parameter to rule out acute myocardial infarction (AMI) at presentation. DESIGN Prospective, multicentre study. MAIN OUTCOME MEASURES We measured hs-cTn using four different methods (hs-cTnT Roche, hs-cTnI Siemens, hs-cTnI Beckman Coulter and hs-cT...
BACKGROUND AND PURPOSE Extended cardiac monitoring immediately after acute ischemic stroke (AIS) increases paroxysmal atrial fibrillation (PAF) detection, but its reliability for detection or exclusion of longer term paroxysmal PAF is unknown. We evaluated the positive and negative predictive value (PPV and NPV) of AF detection early after AIS, for PAF confirmation 90 days later. METHODS We i...
BACKGROUND & AIMS Serial evaluation of hepatitis B virus (HBV) DNA and aminotransferase values is required for identification of inactive HBV carriers (ICs). Recently, HBV surface antigen quantification (qHBsAg) and liver stiffness measurement (LSM) have been proposed as diagnostic tools in chronic HBV infection. The aim of this study was to evaluate the efficacy of HBV DNA quantification, qHBs...
The paper describes model of a new type for valuation of risky bonds and loans that we call Bayesian Multi-Period (BMP) model. BMP is neither structural model nor reduced form and not a Merton-type model at all. BMP proceeds from concept of a risky bond (loan) value as Net Present Value (NPV) of a cash flow, generated by a bond. For a defaultable bond NPV is random value, and BMP identifies “fa...
Recent progress in information and communication technologies has made it possible to measure heart rate (HR) and normalized pulse volume (NPV), which are important physiological indices, using only a smartphone. This has been achieved with reflection mode photoplethysmography (PPG), by using a smartphone's embedded flash as a light source and the camera as a light sensor. Despite its widesprea...
AIM To evaluate (I) trastuzumab-containing primary systemic therapy (PST) in human epidermal growth factor receptor 2 (Her2) overexpressing breast carcinomas.; (II) compare the patients who achieved and those who did not achieve pathological complete remission (pCR), and (III) analyze the accuracy of different clinical-imaging modalities in tumor response monitoring. METHODS 188 patients who ...
D-Dimer testing is used for exclusion of deep venous thrombosis (DVT). AQT90 FLEX D-Dimer (AQT D-Dimer) is a novel time-resolved fluorescence based point-of-care test for quantification of D-Dimer in whole blood or plasma. Presently we have determined the analytical and clinical performance of AQT D-Dimer and compared it with four routine D-Dimer assays. The within-run CV of AQT D-Dimer was 3.8...
Background screening for cognitive impairment in Emergency Department (ED) requires short, reliable tools. Objective to validate the 4AT and 6-Item Cognitive Impairment Test (6-CIT) for ED dementia and delirium screening. Design diagnostic accuracy study. Setting/subjects attendees aged ≥70 years in a tertiary care hospital's ED. Methods trained researchers assessed participants using t...
INTRODUCTION Data regarding the long-term outcome of catheter ablation in patients with nonpulmonary vein (NPV) ectopy initiating atrial fibrillation (AF) are limited. We aimed to evaluate the long-term result of patients with AF who had NPV triggers and underwent catheter ablation. METHODS AND RESULTS The study included 660 consecutive patients (age 54 ± 11 years old, 477 males) who had unde...
OBJECTIVE Administrative health data are important for health services and outcomes research. We optimised and validated in intensive care unit (ICU) patients an International Classification of Disease (ICD)-coded case definition for sepsis, and compared this with an existing definition. We also assessed the definition's performance in non-ICU (ward) patients. SETTING AND PARTICIPANTS All adu...
