Management style in the internal affairs bodies as one of the factors in the formation of the socio-psychological climate of the service team

The article considers the problems of choosing the optimal management style of service teams and improving management personnel in the internal affairs bodies of the Russian Federation. The aim of the research is to study the relationship between the management style and the socio-psychological climate in the team as the basis for the effectiveness of the operational and service activities of the Internal Affairs Bodies. The authors have summarized current scientific and practical research in the field of management style. The classical typology of management styles by K. Levin has been analyzed, which made it possible to develop the most effective leadership style in the internal affairs bodies, ensuring the achievement of the necessary results in the management of collectives. The theoretical material is supplemented with empirical data obtained in the course of annual studies of the socio-psychological climate in the teams of the territorial bodies of the Ministry of Internal Affairs of Russia. Opinion polls of police officers have showed that the highest degree of satisfaction with the service is experienced by those of them who work under the leadership of a democrat leader, focused not only on the performance, but also on creating favorable conditions for the activities of the entire team. The direct dependence of the socio-psychological climate on the management style chosen by the leader has been proved. It has been concluded that it is necessary to implement the mechanisms of the formation of an effective management style existing in the Ministry of Internal Affairs of Russia. For current leaders, it is advisable to envisage an in-depth study of the problem in the classroom for service training, for future leaders - as part of an additional professional program for professional retraining of employees of the Ministry of Internal Affairs of Russia included in the personnel reserve

Prevalence of occult hepatitis B infection among blood donors in Saint Petersburg

The aim of this study was to assess the prevalence of occult hepatitis B infection among blood donors in St. Petersburg, as well as to characterize the identified virus isolates. The study material was represented by 2800 blood plasma samples collected in 2019 from blood donors living in St. Petersburg. The ELISA study for HBV marker rate consisted of HBsAg, anti-HBs IgG, anti-HBcore IgG. HBV DNA was analyzed by nested PCR with real-time hybridization-fluorescence detection on three targets allowing to determine virus DNA at low viral load, including HBsAg-negative chronic hepatitis B. Hepatitis B serological markers were detected in 69.43% of those surveyed, HBsAg was found in 0.43% of individuals, and all of which donated blood first time. A significant excess of the anti-HBcore IgG antibodies occurrence among primary donors (15.1%) compared with repeated/regular donors (7.48%) was shown. The prevalence of virus DNA in the group was 3.14%, including 2.71% of cases in HBsAg-negative CHB. Based on phylogenetic analysis of 88 isolates, HBV subgenotypes were determined in the following order: D1 and D2, 40.91% each, D3 and A2, 9.09% each. While determining the serological subtype in detected isolates, the serotype ayw3 (52.27%) vs ayw2 (46.59%) and adw2 (10.23%) prevailed. Drug resistance mutations, including compensatory ones, were detected in six examined patients (6.82%). In all genotype D isolates, multiple amino acid substitutions were identified in the RT, SHB, MHB, LHB, and Core regions; mutations in the preCore region were detected in 21.59% samples. In the MHR of the HBV genotype D genome, twenty-six positions were identified in which amino acid substitutions occurred, and all isolates showed modifications at positions 113, 114, 131, 134, 159, 161, 168, in 76 — at position 122, in 68 — at position 127, in 36 — at position 118, in 24 — at position 128. In HBV A2 isolates, mutations T113S, S143T, Y161F were identified. Nine isolates in the preCore region showed a polymorphism including a stop codon W28*W; in five isolates the W28S substitution was shown in the same position, and the W28*S variant was found in one more sample. The high incidence of HBsAg-negative CHB cases among blood donors, as well as the predominance of HBV isolates that simultaneously carry mutations resulting in diagnostic failure of HBsAg tests and prophylactic failure of immunoglobulin or vaccines and virus reactivation, mutations that contribute to disease progression obviously pose a threat to health and require to be further examined
