Healthcare Workers' Acceptance of COVID-19 Vaccination in Russia.

During the COVID-19 pandemic, the problem of the population's adherence to vaccination has become significantly aggravated around the world. This study is aimed at evaluating healthcare workers' (HCWs) acceptance of COVID-19 vaccination in Russia. A cross-sectional multicenter study was carried out by interviewing HCWs in Russia using an electronic questionnaire and snowball sampling.

Cost effectiveness and budget impact of universal varicella vaccination in Russia.

This economic evaluation assesses the cost-effectiveness and budget impact of introducing a two-dose varicella vaccine in the Russian national immunization program. A static Markov model followed a simulated 2019 Russian cohort over its lifetime and compared outcomes and costs of three varicella vaccination strategies: strategy I (doses given at 12 and 15 months of age), strategy II (doses given at 1 year and 6 years of age), and a no vaccination scenario. Inputs on age-dependent clinical pathways, associated costs, and related health outcomes were collected from national sources and published literature.

Estimating global injuries morbidity and mortality: methods and data used in the Global Burden of Disease 2017 study.

Background: While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria.

Methods: In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation.

Global trends of hand and wrist trauma: a systematic analysis of fracture and digit amputation using the Global Burden of Disease 2017 Study.

Background: As global rates of mortality decrease, rates of non-fatal injury have increased, particularly in low Socio-demographic Index (SDI) nations. We hypothesised this global pattern of non-fatal injury would be demonstrated in regard to bony hand and wrist trauma over the 27-year study period.

Methods: The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 was used to estimate prevalence, age-standardised incidence and years lived with disability for hand trauma in 195 countries from 1990 to 2017.

Sample study protocol for adapting and translating the 5C scale to assess the psychological antecedents of vaccination.

Introduction: Published in 2018, the 5C scale is psychometrically validated to assess five psychological antecedents of vaccination (confidence, complacency, constraints, calculation and collective responsibility). The original version offers a validated English and German scale to assess these determinants with a short 5-item scale (1 item per antecedent) and a long 15-item scale (3 items per antecedent). This sample study protocol provides a step-by-step guidance for the process of adapting the 5C scale to another country, language or cultural context.

[PRINCIPLES OF MONITORING OF ADVERSE EVENTS AFTER VACCINATION IN RUSSIAN FEDERATION AND THE WORLD].

Difference in terminology accepted in our and foreign countries for designating disease of post-vaccination period is shown. Analysis ofthe existing regulating documents in Russian Federa- tion regarding registration of adverse events in post-vaccination period and system of registration accepted in many countries of the world and recommended by WHO is presented. In Russian Federation in accordance with the documents ofthe Federal Service of Surveillance for Protection of Consumers Rights and Human Welfare only certain conditions (post-vaccinal complications) are subject to registration.

Safety and immunogenicity of a single dose 23-valent pneumococcal polysaccharide vaccine in Russian subjects.

Unlabelled: Pneumococcal infection is a major cause of pneumonia, bacteremia, and meningitis. Incidence of pneumococcal disease (PD) varies worldwide. The 23-valent pneumococcal polysaccharide vaccine (PPV23) displays an acceptable safety profile and has been demonstrated cost-effective in reducing burden of PD.

[UNIVERSALITY OF CHANGES IN EPIDEMIC PROCESS MANIFESTATIONS OF ANTHROPONOSIS INFECTIONS IN RECENT DECADES].

Aim: Detection of main regularities of anthroponosis infections with various degrees of manageability and factors that determine them in contemporary social-demographic conditions.

Materials And Methods: A comparative retrospective epidemiologic analysis of morbidity of the population with viral hepatitis A, Sonnei and Flexneri shigellae, rotavirus infection, pertussis, diphtheria, varicella, rubella, pneumococcal infection and possible risk factors by 47 European countries and territories of Russian Federation was carried out, the maximum depth of search was 89 years.

Results: Common epidemiologic regularities were shown to be characteristic for anthroponosis infection regardless of the degree of their manageability, that are manifested by the presence of large and small cycles in the multi-year dynamics of morbidity changes of age-related morbidity structure and its pronounced territorial non-uniformity.

The paper gives the definition, goal, and objectives of clinical epidemiology. The latter is shown to be an epidemiology section that makes it possible to elaborate evidence-based standards for diagnosis, treatment, and prevention and to select a respective algorithm of actions for each specific clinical case. Randomized controlled trials are the gold standard for obtaining evidence.

Aim: To study features and risk factors of soft tissue's invasive streptococcal infection in surgical unit's patients: a) emm-types of the most often recovered streptococcus; b) human immune response for streptococcal antigens (streptolysin-O and the group A carbohydrate antigen); c) main patient's conditions that complicate the course of soft tissue's streptococcal infection.

The objective of the present study was to characterize peculiar clinical and laboratory features of trivial tonsillitis for the substantiation of the necessity of prescription of antibacterial therapy. A total of 386 patients presenting with various forms of trivial tonsillitis were available for the determination of anti-streptococcal antibody (ASLO, anti-DN-ase B, ASPH) levels. The results of the measurement were compared based on the Centor scale generally used to estimate the necessity of prescribing antibacterial therapy for the treatment of sore throat.
