Infective endocarditis (IE) is a important heart disease with high morbidity and mortality. Current guidelines suggest antibiotic prohylaxis (AP) to individuals having risk of IE. These include patients background IE, biological or mechanical prosthetic valve, surgically constructed systemic pulmonary conduit shunt. The restriction AP due concerns about increased comprehension regarding daily i...

Image encryption algorithm based on a two-dimensional Chebyshev-Logistic-Infinite Collapse Map (2D-CLICM) is proposed. A new chaotic map designed, and numerical studies show that 2D-CLICM has larger region, better randomness more complex behavior. An image (CLICM-IE) developed the 2D-CLICM. The randomly generated key used to generate random sequences security greatly improved. To obtain lower c...

Abstract This article proposes a new approach to estimate the informal economy (IE) by using Structural Equation Modeling (SEM). Using Monte Carlo Simulation and empirical analysis of Italian IE as an example, we provide general conclusions on reliability limitations SEM IE. Practical guidelines how apply this method way deal with most problematic issues are provided. We conclude that may be ef...

Most of the information stored in digital form is hidden in natural language texts. Extracting and storing it in a formal representation (e.g. in form of relations in databases) allows efficient querying, easy administration and further automatic processing of the extracted data. The area of information extraction (IE) comprises techniques, algorithms and methods performing two important tasks:...

BACKGROUND Data on early determinants of outcome in infective endocarditis (IE) are limited. We evaluated the prognostic significance of early clinical characteristics in a large, prospective cohort of patients with IE. METHODS AND RESULTS Two hundred sixty-seven consecutive patients with definite or possible IE by modified Duke criteria and echocardiography performed within 7 days of present...

Eleven of 138 patients with infective endocarditis (IE) who underwent cardiac valve replacement for IE during a 12 1/2-year period had active IE. Eight of the 11 (all with aortic IE) had positive blood cultures within 48 hours preoperatively; six of the eight had positive Gram stains and cultures of the excised cardiac tissue. All 11 patients had Class IV cardiac functional disability (New York...
