    e article examines the effect of providing the necessary physical, mechanical and operational characteristics of the road pavement material from cement concrete intended for highways. Studies carried out in this area have shown that the technical, economic and operational characteristics of such coatings are largely due to the rational choice of the material composition. In the author's proposed work, a study was made of the effect of durability under compression (fck.cube) and on bending (fctk) and abrasion (G). Changes in these characteristics are achieved by introducing into the cement concrete plasticizer (Dynamon Easy 11), filler (microsilica) and polypropylene fiber (MAPEFIBRE NS 12/ NS 18). The obtained researches made it possible to draw a conclusion that, with rational selection, the composition significantly increases the physico-mechanical and operational characteristics of the material of the pavement from cement concrete

    The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). AIMS: The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). METHODS AND RESULTS: Prospective cohort of 3116 adult patients (2470 from Europe, 646 from non-ESC countries), admitted to 156 hospitals in 40 countries between January 2016 and March 2018 with a diagnosis of IE based on ESC 2015 diagnostic criteria. Clinical, biological, microbiological, and imaging [echocardiography, computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)] data were collected. Infective endocarditis was native (NVE) in 1764 (56.6%) patients, prosthetic (PVIE) in 939 (30.1%), and device-related (CDRIE) in 308 (9.9%). Infective endocarditis was community-acquired in 2046 (65.66%) patients. Microorganisms involved were staphylococci in 1085 (44.1%) patients, oral streptococci in 304 (12.3%), enterococci in 390 (15.8%), and Streptococcus gallolyticus in 162 (6.6%). 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in 518 (16.6%) patients and presented with cardiac uptake (major criterion) in 222 (42.9%) patients, with a better sensitivity in PVIE (66.8%) than in NVE (28.0%) and CDRIE (16.3%). Embolic events occurred in 20.6% of patients, and were significantly associated with tricuspid or pulmonary IE, presence of a vegetation and Staphylococcus aureus IE. According to ESC guidelines, cardiac surgery was indicated in 2160 (69.3%) patients, but finally performed in only 1596 (73.9%) of them. In-hospital death occurred in 532 (17.1%) patients and was more frequent in PVIE. Independent predictors of mortality were Charlson index, creatinine > 2\u2009mg/dL, congestive heart failure, vegetation length > 10 mm, cerebral complications, abscess, and failure to undertake surgery when indicated. CONCLUSION: Infective endocarditis is still a life-threatening disease with frequent lethal outcome despite profound changes in its clinical, microbiological, imaging, and therapeutic profiles
