Objective. To study the etiology of community-acquired pneumonia (CAP) in adult hospitalized patients after the COVID-19 pandemic. Materials and Methods. The prospective multicenter study included patients 18 years and older with confirmed diagnosis of CAP admitted to 6 hospitals in different regions of Russia from July to November 2023. Etiology was confirmed by respiratory samples (sputum, tracheal aspirate) culture, blood culture (severe cases), and urinary antigen tests (Legionella pneumophila serogroup 1, Streptococcus pneumoniae).

Objective. To study the real practice of management of patients with COPD exacerbations on the example of a single hospital. Materials and Methods. During the retrospective descriptive study the data of medical records of 219 patients with COPD were processed, the profile of the studied patients with distribution by phenotypes and determination of the Charlson comorbidity index was compiled and analyzed. StatPlus 7.0 program was used for statistical analysis.

Objective. To assess the etiology of infections, microbial associations and antimicrobial resistance in a burn intensive care unit. Materials and Methods. A microbiological study of 1322 biological samples from 195 patients with extensive burns included 479 blood samples, 82 respiratory samples, 326 urine samples, and 435 wound samples. Antimicrobial susceptibility testing was performed, and coefficients of constancy and associativity (CA), as well as the Jaccard coefficient were calculated. Results. The etiology of infections was represented by: Pseudomonas aeruginosa – 23%, Acinetobacter baumannii – 19.

Objective. To review a literature published over the past 5 years and our own data on the etiology of lower respiratory tract infections (LRTI), antimicrobial resistance and its relationships between sepsis and choice of appropriate antibiotic therapy. Materials and Methods. National Nosocomial Infections Surveillance (NNIS) criteria were used to diagnose LRTI. A review of the articles regarding LRTI from the Russian and international English language journals published over 6 years was performed.

Objective. To investigate the mortality rate, comorbidity prevalence, and etiology of community-acquired pneumonia (CAP) in elderly patient population. Materials and Methods. Hospitalized elderly patients with CAP were distributed into the following age groups: 65–74 years (group I), 75–84 years (group II) and 85–94 years (group III). The patients’ medical records were used for determining comorbidities and mortality rate. In order to determine etiology of CAP, sputum or BAL samples were collected.

Objective. To investigate etiology of infective endocarditis in Russian Federation. Materials and Methods. Multicenter prospective (September 2011 to December 2013) and retrospective (January 2006 – September 2011) studies to investigate etiology of infective endocarditis (IE) were performed at medical institutions in 10 Russian cities. Patients with definite or possible diagnosis of IE who have at least 1 blood culture collected were enrolled in the study. Results. A total of 401 patients with IE were included in the analysis: 161 (40.

Objective. To reveal the level of knowledge of medical specialists on the diagnostics and treatment of infective endocarditis (IE). Materials and Methods. Multicenter interviewing of the medical specialists about IE etiology, diagnostics and treatment was conducted during 2012–2013 in 15 cities of different regions of Russia. Results. Overall 530 medical specialists were interviewed. On the question concerning the choice of echocardiographic study only 59,4% of respondents have marked transesophageal route.
