RESUMO

COVID-19 is caused by an airborne virus, SARS-CoV-2. The upper respiratory tract (URT) is, therefore, the first system to endure the attack. Inhabited by an assemblage of microbial communities, a healthy URT wards off the invasion. However, once invaded, it becomes destabilised, which could be crucial to the establishment and progression of the infection. We examined 696 URT samples collected from 285 COVID-19 patients at three time-points throughout their hospital stay and 100 URT samples from 100 healthy controls. We used 16S ribosomal RNA sequencing to evaluate the abundance of various bacterial taxa, α-diversity, and ß-diversity of the URT microbiome. Ordinary least squares regression was used to establish associations between the variables, with age, sex, and antibiotics as covariates. The URT microbiome in the COVID-19 patients was distinctively different from that of healthy controls. In COVID-19 patients, the abundance of 16 genera was significantly reduced. A total of 47 genera were specific to patients, whereas only 2 were unique to controls. The URT samples collected at admission differed more from the control than from the samples collected at later stages of treatment. The following four genera originally depleted in the patients grew significantly by the end of treatment: Fusobacterium, Haemophilus, Neisseria, and Stenotrophomonas. Our findings strongly suggest that SARS-CoV-2 caused significant changes in the URT microbiome, including the emergence of numerous atypical taxa. These findings may indicate increased instability of the URT microbiome in COVID-19 patients. In the course of the treatment, the microbial composition of the URT of COVID-19 patients tended toward that of controls. These microbial changes may be interpreted as markers of recovery.

RESUMO

The review article provides information about the features of the Varicella-zoster virus (VZV), about the clinical manifestations of CNS damage in acute and chronic VZV infection in children and adults, about the mechanisms of interaction of the pathogen with the immune system during the development of the disease. The question of whether to consider neurological disorders in VZV infection as a complication or manifestation of the disease caused by a defective virus or the presence of subclinical immunodeficiency is discussed, which is confirmed by modern scientific studies. The critical mechanisms of immune defense against VZV, which are the main reason for the penetration of the virus into the CNS and the development of neurological disorders, as well as the relationship between VZV genotypes, the presence of mutations in the gE gene and the nature of the course, the identification of rare variants of the POLR3A, POLR3C, POLR3E and POLR3F genes associated with violation of IFNs induction, and the development of severe VZV infection, in which vasculopathy also occurs, which is the basis for the use of vascular drugs of complex action, such as Cytoflavin, the effectiveness of which has been proven by the authors. A special place is given to the analysis of intrathecal immunopathogenesis, which is likely to be associated with the presence and severity of neurological manifestations, their relapses. The issue of the causes of the development of a severe course of the disease in patients vaccinated against chickenpox, as well as the issue of resistance to specific antiviral drugs, probably associated with the presence of mutations responsible for the resistance of the virus to therapy, is discussed.

RESUMO

Economic evaluation of workers' health disorders risk could include cost equivalent not of health itself, but a prevented risk for worker's health. The authors evaluated a potential underproduced output during disablement period and changes of tax proceeds (except gross domestic product losses). This approach was tested in evaluating risk for.health of workers engaged into underground mining on potassium salts extraction enterprise. Mathematic models of unfavorable effects development enabled to follow dynamics of these effects and forecast possible development of diseases in the studied workers group.

RESUMO

The article deals with the study of dynamics of population mortality in the Russian Federation as a result of acute intoxications in 2001-2010. In the Russian Federation, during the examined period, population mortality due to casual acute alcoholic intoxications decreased up to 2.1 times. The most rapid race of mortality decrease occurred in the Central Federal Okrug and the slowest race was established in the Siberian Okrug. The highest population mortality rate as a result of alcoholic intoxications is in the Siberian Okrug and the lowest ones--in the South Okrug. The analysis of mortality rates as a result of chemical intoxications and their dynamics will allow to assess the toxicological situation and to determine the strategic directions of preventive activities in the area of chemical security on the regional level.

RESUMO

The basic results of the study of the general disease incidence and the pathological affectedness of the inmates of children's homes of Omsk oblast during 2000-2005. The respiratory diseases, the diseases of digestive system, the ophthalmic and accessory apparatus diseases, the infectious and parasitogenic diseases, the diseases of nervous system predominate in the structure of morbidity of the children-orphans. According the medical examination data, the percent of the healthy children does not exceed 9% and the percent of the children with chronic diseases makes up to more than 40%. The assessment of the subjective status of the school-age orphans revealed the discrepancy of their appraisal of state of health, physical activity and emotional conditions which is caused by the social immaturity and the fatigue.

RESUMO

Complex impact of various factors on development of chronic diseases among adolescents aged of 15-17 years and dwelling in districts of Omskaya oblast is analyzed. It is noted that out of twelve factors four of them are of educational pedagogic category. Besides, one of these (the twelfth) takes second rank place emphasizing that making necessary hygienic conditions of education is of highly significance for maintenance of adolescent health. The most pronounced effect on development of chronic pathology among adolescents is produced by habitation conditions, timeliness and quality of applied health-improving medical activities during childhood. All educational pedagogic and some other factors can be controlled setting up thereby reserve for decreasing adolescent morbidity.

RESUMO

The morbidity structure was analyzed in children vaccinated against epidemic parotitis in 1993-2002. Eight children (4 with serous meningitis and 4 with lesions of the salivary glands) underwent virologic and immunologic examinations. The molecular typing of the SH-gene fragment of the parotitis virus showed the process in 7 cases to be provoked by the vaccination strain. Presumedly, progressing vaccine-associated meningitis inhibits antibody formation. The total incidence of vaccine-associated meningitis was shown, according to Saint Petersburg data, to be not high, which testifies to a low reactogenicity of the Russian vaccine strain.

RESUMO

Human health changes occurring in the presence of active migratory processes were analyzed in a rural area of the Orenburg region in 1995 to 2000. There were increases in morbidity and mortality rates. The rates of deaths caused by accidents, injuries and intoxication were noted to rise in the structure of mortality in the able-bodied population. The total mortality rate in the adult population in the area exceeds the average one of Russia. There is an evident tendency for an increase in the incidence of some most important non-epidemic diseases in the population. This all provides evidence for that its necessary to work out a system of preventive measures and, first of all, among socially disadapted strata of society.

RESUMO

Four levels (types) of immune response, differing by expression of cytokines (TNF-alpha, IL-1 beta, IL-4, and gamma-IFN) and immunoglobulins IgG2, IgG3, IgG4, and IgE) and by expression and time course of specific cell-mediated and humoral immune response, were detected in children with different clinical forms of mumps. Types 1 and 3 immune response are predominantly cell-mediated, while types 2 and 4 predominantly humoral during the acute phase of the disease. The cytokine and antigen-specific profiles of each type of immune response correlate with the severity of clinical course of mumps.

RESUMO

The author presents the data of medical social study of disability caused by chronic nonspecific diseases of the lungs (CNDL) in Omsk and the Omsk region and analyzes the level, structure, and time course of primary disability in relation to sex, age, place of residence, and disability group. Working loss caused by CNDL in cities and in the country is evaluated. Factors promoting the formation of disability in CNDL are evaluated. One of important factors is the quality of check-ups of patients. The majority of risk factors can be controlled, which creates a certain reserve for decreasing disability in CNDL.
