BACKGROUND AND OBJECTIVE Pepsinogen levels in plasma are increased by inflammation in the gastric mucosa, including inflammation resulting from Helicobacter pylori infection. A decrease in pepsinogen II level has been suggested as a reliable marker to confirm the successful eradication of infection. The aim of our study was to evaluate the potential role of(More)
OBJECTIVE We have compared the performance of two faecal immunochemical tests (FIT) in an average-risk population. MATERIALS AND METHODS Altogether, 10 000 individuals aged 50-74 were selected randomly from the population of Latvia in 2011 and assigned randomly either to OC-Sensor or to FOB Gold single-time testing. Positivity of the test, frequency of(More)
This paper studies the techniques of performance enhancement for decision tree classifiers (DTC) that are based on data structure analysis. To improve the performance of DTC, two methods are used – class decomposition that uses the structure of class density and taxonomy based DTC design that uses interactions between attribute values. The paper shows(More)
INTRODUCTION Population-based eradication of Helicobacter pylori has been suggested to be cost-effective and is recommended by international guidelines. However, the potential adverse effects of widespread antibiotic use that this would entail have not been sufficiently studied. An alternative way to decrease gastric cancer mortality is by non-invasive(More)
Enterprise applications are used for managing operational data and are aimed at improving business efficiency. Many enterprise applications have been developed over the past three decades and are often referred to as legacy systems. Usually they are monolith, inflexible, poorly documented and hard to maintain. These issues can be addressed by improving(More)
BACKGROUND Circulating levels of pepsinogens have been used in high gastric cancer-risk Asian and European populations to triage endoscopic evaluation for more severe pathology. There are different analytic methods with uncertain correlations. We therefore compared diagnostic performance of three commonly used pepsinogen assays to detect histologically(More)
