Hyponatremia is more common in the elderly. A number of studies suggest that even mild chronic hyponatremia is a serious danger, increasing the risks of developing geriatric syndromes, falls, low bone density, fractures, cognitive impairment, and death of all causes. Although the mechanism for the development of such complications is currently not completely clear. Questions remain about the need and methods for correcting this condition, although there is some evidence that the correction of hyponatremia improves cognitive functions, postural balance, minimizing the risk of falls and fractures. These issues are addressed in this review of the literature.Currently one of the most important problems facing biobanking specialists is the standardization of biobanks operation. Close attention is paid to this issue by international biobanking organizations, such as ISBER and BBMRI-ERIC, which develop regulatory documentation in this area. The article provides examples of standardization tools - implementation of the ISO 9001 quality standard and ISBER Best Practices. General information about the development, scope, and structure of the ISO 20387 standard is provided. The standard does not provide ready-made solutions and does not contain specific requirements for storage temperature or biosamples processing in biobanks, allowing each biobank to adapt its own management system to existing conditions and needs. The standard contains requirements for both the organization of the biobanking and the supporting processes - personnel competence; requirements for biological safety; infrastructure management, including equipment used by the biobank, environmental parametehe national and international level, based on the application of common quality standards in the work.The relevance of the study of the general principles and patterns of legal regulation of access storage processes and data protection of genome sequencing in foreign countries is determined by the need to develop a general concept of legal regulation of this type of activity in Russia. The purpose of this study is to develop the system-forming principles and patterns of access storage and data protection of genome sequencing in Russia. To achieve this goal, tasks were set and solved to identify and study the general principles and patterns of legal regulation of access storage processes and data protection of genome sequencing in foreign countries. The international documents regulating the features of regulation of access storage processes and data protection of genome-wide sequencing, the doctrinal sources of Great Britain, the USA, France, Israel, and Japan are studied. Methods used general philosophical, general scientific, private scientific, special (structural-legal, comparative-legal, formal-legal).

Plasma samples were used from 196 patients residing in the Northwestern Federal District. Serological HBV markers were found in 79.6% of cases. However, HBsAg was detected in 5.6% of patients. Anti-HBcore IgG antibodies are found in 62.24% of cases, anti-HBe IgG antibodies in 27.55%, anti-HBs IgG antibodies in 52.55% of cases. Using a commercial kit with a 100 IU / ml sensitivity, HBV DNA was detected in 4.6% of patients, that is, 81.8% of HBsAg-positive individuals. Using the method developed by us, HBV DNA was found in 18.36% of HIV-infected individuals, including 12.75% of cases was HBsAg-negative (latent) disease form. In the examined group, HBV of genotype D prevailed (91.7%), genotype A was detected in 8.3% of cases. The distribution of subgenotypes is presented in the following ratios D2 - 55.6%, D1 - 22.2%, D3 - 13.9%, A2 - 8.3%. Mutations were dhe virus in patients with HBV can help predict the clinical course and disease progression, and ART complications. To reduce the HIV HBV co-infection burden and to appointer anti-HBV therapy, it is necessary to introduce detection the occult HBV to modify the algorithm for CHB laboratory diagnosis.The aim of the work was to develop an accelerated genodiagnosis method based on mPCR-RT for the detection DNA of B. pertussis, B. parapertussis, B. holmesii.

The study used 104 strains of microorganisms, of which 50 strains of B. pertussis, 37 - B. parapertussis, 17 - heterologous species of microorganisms. Assessment of analytical specificity was carried out using DNA strains of various microorganisms with a concentration at least 109 GE / ml. To check the analytical sensitivity we studied a series of serial dilutions of bacterial cultures of the control strains B. pertussis № 143, B. parapertussis № 38b, B. holmesii DSM 13416 with a concentration of 5x109 - 5 μm/ml.

Insertion sequences were chosen as diagnostic targets for B. parapertussis - a specific fragment IS1001, for B. holmesii - a specific fragment hlIS1001, for B.pertussis - a fragment IS481. To develop a genodiagnosis method specific primers were designed and combined into a single multi-primer mixture, the composition of the reaction mixture and the amplification conditions were selected. The analytical sensitivity of the developed method for detecting pertussis and pertussis-like pathogens was 5×101 GE / ml. Verification of the developed methodology of gene diagnostics showed 100% analytical specificity.

An accelerated genodiagnosis method based on mPCR-RT has been developed, it allows you to identify DNA of B. pertussis, B. parapertussis, B. holmesii, which expands the possibilities of examining patients with suspected pertussis and pertussis-like diseases in order to increase laboratory confirmation of the diagnosis.

Analyze the spectrum of the leading causative agents of osteomyelitis, their antibiotic sensitivity, and also the adhesive activity of the identified bacterial associations. A microbiological analysis of 2197 smears of adult patients with various etiological forms of osteomyelitis who were treated in the departments of the purulent center of the FSBI «NMRCTO» of the RF Ministry of Health in 2019. The spectrum of pathogenic microflora, sensitivity to standard antibacterial drugs used in the clinic was studied. this website The biofilm-forming ability of associations of microorganisms was investigated. According to the conducted microbiological monitoring for 2019, the microflora spectrum for osteomyelitis is diverse, the main pathogens are S. aureus, S.
