Relevance. Currently, the national calendar of preventive vaccinations does not provide for revaccination against whooping cough in children over the age of 18 months. At the same time, the epidemiological and economic feasibility of revaccination against whooping cough in children aged 6–7 years, as well as adolescents, has been demonstrated in world practice. Aim. Based on a mathematical model, develop a forecast of pertussis morbidity dynamics and assess the potential socio-economic damage under the current and expanded vaccine prophylaxis algorithms.Methods. Mathematical modeling of the potential effect of revaccination against whooping cough in children aged 6–7 years (scenario 1) and at 6–7 years and 14 years (scenario 2) was carried out within the framework of the national calendar of preventive vaccinations. A simulation dynamic mathematical model is constructed that allows predicting the development of the epidemiological process of whooping cough on the basis of the dynamics of the main indicators of its prevalence in the population that developed in previous years. The model took into account dynamic changes in the preventive effectiveness of vaccinations and the potential level of underestimation of morbidity. The obtained arrays of indicators served as the basis for extrapolating trends in morbidity and mortality until 2034.The calculation of epidemiological benefits was carried out in the metrics of prevented loss of years of life under the two scenarios under consideration in comparison with the current vaccination algorithm. The calculation of the economic effect was carried out on the basis of the obtained indicators of epidemiological benefits in the metrics of the monetary equivalent of the average cost of a year of life, taking into account the projected inflation coefficients until 2034.Results. The projected decrease in the number of years of life lived in a state of illness, in comparison with the current situation, will total 44.5 thousand years for the period 2019–2034 under scenario 1 and 66.7 thousand years under scenario 2. The socio-economic damage from prevented cases of the disease, expressed in the monetary equivalent of the average cost of living, will decrease by 28.6% (scenario 1) or 42.0% (scenario 2).Conclusions. A comparison of the received public benefits with the costs of vaccination shows that the expansion of the NCPP with additional revaccinations against whooping cough (at 6–7 years or at 6–7 and at 14 years) is advisable both in epidemiological and economic aspects.

Relevance. Monitoring the genotypic diversity of the hepatitis C virus as well as its prevalence in the population, including in certain population groups, is an important public health task.Aim. To analyze main epidemiological indices (incidence and prevalence) among people living with HIV and evaluate abundance of chronic hepatitis C among them, reveal molecular-genetic distribution of hepatitis C virus (HCV) isolated from HIV-positive people living in the Far Eastern Federal district (FEFD) of the Russian Federation.Materials and methods: a retrospective epidemiological analysis including estimation of HIV-infection incidence and prevalence as well as percent of HIV-positive people suffering from chronic viral hepatitis C was conducted for nine constituent entities of the FEFD. Molecular genetic analysis included evaluation of 120 samples of serum positive for HCV RNA that was obtained from people diagnosed with HIV-infection. A type-specific commercial PCR test-kit as well as partial sequencing by Sanger of HCV NS5B gene (241 bp and 350 bp) were utilized in order to specify HCV genotypes.Results and discussion: in total 26.26% of people living with HIV were registered for regular medical examination due to chronic hepatitis C in the FEFD in year 2019. Their percentage has grown over a 5-year period. Dominant HCV subtype among surveyed HIV-positive people was subtype 3a followed by HCV subtype 1b. HCV genotype 2 and subtype 1a were detected less frequently and were identified as minor genotypes. Genotype distribution among people aged under 35 years was more significant in comparison with older citizens. Some regional particularities were discovered. For example, HCV genotype 2 was registered more frequently in the Khabarovsk krai compared to mean estimated value of the sampling collection. Subtype 1b was dominant in Republic Sakha (Yakutia).Conclusion: an increase in percent of HIVinfected people suffering from chronic hepatitis C has been noted during a 5-year period. Should be noted that the value varies in different constituent entities ofthe FEFD. Molecular-genetic analysis showed general prevalence of HCV 3a subtype while 1b HCV subtype is dominant in the Russian Federation in patients suffering from HCV-monoinfection as well as in those infected with HIV and HCV.

Relevance. The geographical spread of HIV infection among the population of various administrative territories is very heterogeneous. The Tyumen region, due to its vast territory and the significant remoteness of some areas from the regional center, is of particular interest in the framework of considering the territorial features of the spread of HIV.Aims. To consider peculiarities of the spread of hiv infection among urban and rural residents of the Tyumen region in 1993–2019.Materials & Methods. Statistical data of the «Center for the Prevention and Control of AIDS» in the period from 1993 to 2019, annual form No. 61 «Information on the contingents of HIV patients» for 2006–2019, materials of the state report «On the sanitary and epidemiological situation in the Tyumen region» for 2013–2019. Methods of epidemiological observation were used in the work: analytical and descriptive-evaluative with the use of methods of retrospective and operational analysis and statistical methods.Results and Discussions. A specific feature of the spread of HIV infection among urban and rural residents is the tendency to exceed the regional incidence rate in a number of territories. Analysis of epidemiological data for the period under review showed that all territories of the region are involved in the epidemiological process of HIV infection, and in a number of territories the prevalence rate exceeds the average Russian level. HIV prevalence as of December 31, 2019 was 728.2 per 100 thousand people in Russia. In 17 administrative territories of the Tyumen region the infection rate is higher than the national average level and is per 100 thousand population in the city of Tobolsk – 1903.3, in the districts of Uvat – 1486.2, Tobolsk – 1440.5, Nizhnetavda – 1354.9, Tyumen – 1344.1, Yalutorovsk – 1327.6), in the city. Tyumen – 1249.3, in the districts: Vagay – 1195.2, Zavodoukovsky – 1119.2, in Ishim – 951.8, in the districts: Yarkovsky – 889.6, Vikulovsky – 881.3, Yurginsky – 846.9, Ishimsky district – 842.1, Aromashevsky – 851.6, Isetovsky – 754.4, Uporovsky district – 734.7.Conclusions. The HIV epidemic in the Tyumen region is determined by its economic and geographic location and by the presence of exceptional epidemiologically significant prerequisites for the intensive spread of HIV, in particular, by the routes through which large quantities of drugs are illegally transported (drug trafficking from the northeast).

Backgrounds — Students who graduated from high school and went to university have to consider and make a decision about their choice of university major, an extremely important decision to each of them, which can greatly influence their studying road, future occupation and even whole life. Purpose — The purpose of the research is to find out the main factors influencing NAU students’ choice of major. In addition, this research also aims to determine how Personal Factors, Family Factors and Profession Factors influence NAU students’ choice of major respectively. Methodology — We based on the previous research and narrowed three main factors including Personal Factor, Family Factor and Profession Factor as the main variables, then we conducted a questionnaire survey among all NAU students of different majors and grades, finally we analyzed the data that we collected and drew some conclusions. Results — We find that students have some knowledge of their major before they entering the university rather than knowing nothing, the Profession Factor is the top factor which is the biggest influence on the students’ choice of major, however, though some minor factors which belong to the Profession Factor have an important place, the dominant factor is still the Gaokao Score which belongs to the Personal Factor. As for those students who have changed their major, they more tend to choose Auditing, Accounting and Finance because of the professional advantages, only a few students are still dissatisfied with their chosen.

Be a Good Listener — Exploration of Education Transformation Strategies for Left-behind Children
Authors: Bao Caixia 
Published: November 2021

The education of left-behind children is an important issue in the development of education at present. The emergence of left-behind children is caused by economic transformation and social development. Rural people have always be willing to change their living conditions and improve their living standards, so the parents of rural children have to leave their hometown and come to the city to find a better chance to make a living, but some rural parents are still engaged in the rural orchards, small workshops and other self-employed business. Whether migrant workers or start a small business, or stay in the countryside to operate small business, child's education is bound to be affected to some extent, as a result, the vast majority of the seventy percent of the rural parents wish their children to be looked after by old people, and the parents are not at home for a long time, so they can't take care of the children in learning and life. As a compulsory education worker, we should understand the characteristics of left-behind children and carry out an analysis and research on the education of left-behind children.
