Introduction: Liver cirrhosis is a major but preventable cause of health loss worldwide. The era of «big data» allows us to evaluate this nosology in a new format., Purpose: Evaluation of the registered population of patients with cirrhosis of the liver of cirrhosis of various etiology in Moscow. Moscow., Materials and Methods: Based on the data of the Moscow Department of Healthcare for the drug provision for the period from 2017 to 2019. Тhe population of patients with an established diagnosis of liver (other etiology) was characterized according to ICD-10 code K.74 (K74.0-74.6) according to the International Statistical Classification of Diseases and Related Health Problems of the 10th revision., Results: Over a 4-year period, more than 2 thousand patients with established diagnosis of liver cirrhosis received preferential drug provision in Moscow. The largest part of the population of patients with liver cirrhosis receiving preferential drug provision in Moscow is represented by the patients of age groups 40-59 years old and 60-79 years old, the groups 30-39 years old and 80-99 years old were comparable annually. There was a decrease in the number of patients with liver cirrhosis in the age groups of 30-39 and 18-19 years compared with the base year (2017) by 37% and 57%, respectively. At the same time, in pediatric patients (from the neonatal period to 17 years), there was an intensive increase in patients from 52 to 550% compared to the baseline year (2017).

Ensuring effective epidemiological surveillance of tuberculosis is essential and one of the paramount tasks for any national tuberculosis control program. The article analyzes the organization of the tuberculosis epidemiological monitoring system at the level of the subject, based on the experience of implementing such a system in the city of Moscow in 1996-2020, defines its tasks and principles of its construction. The systems of epidemiological monitoring of tuberculosis, implemented taking into account the developed principles, provide an analysis of the epidemiological situation in the territory, the results of which can be successfully used for making managerial decisions, program-target planning and evaluating the effectiveness of the measures taken.

Mycoplasma genitalium is a widespread sexually transmitted infection (STI) with growing rate of antimicrobials resistance. In our study, 137 vaginal and 131 urethral M. genitalium-positive swabs were sequentially collected through the work of Reference Center for STI during 2019. For prevalence evaluation of macrolide-resistance mutations three commercially available kits were used: AmpliSens® M. genitalium-ML/FQ-Resist-FL (Central Research Institute of Epidemiology, Russia), ResistancePlus® MG (SpeeDx, Australia), and S-DiaMGRes™ (Diagenode, Belgium). Macrolide resistance mutations were detected in 16% (43 of 268) of samples. Diagnostic characteristics were evaluated against Sanger sequencing. For AmpliSens® M. genitalium-ML/FQ-Resist-FL specificity was shown to be 100% (CI 95%, 98.4-100), and sensitivity was 90.7% (CI 95%, 77.9-97.4). ResistancePlus® MG specificity was 100% (CI 95%, 98.3-100), and sensitivity was 92.1% (CI 95%, 78.6-98.3). S-DiaMGRes™ specificity was shown to be 88.6% (CI 95%, 83.9-92.4), and sensitivity was 100% (CI 95%, 84.4-100). Mutations of parC gene region were detected in 14.5% (38 of 268) using AmpliSens® M. genitalium-ML/FQ-Resist-FL with further validation by Sanger sequencing. Of studied samples, 6.3% (17 of 268) contained both antimicrobials of class resistance mutations. Prevalence of macrolide-resistant M. genitalium in Moscow was 21.7% (23 of 106) and of fluoroquinolone-resistant M. genitaliuim was 20.8% (22 of 106). In Moscow region, macrolide-resistant M. genitalium were 12.3% (20 of 162) and 9.9% (16 of 162) of fluoroquinolone-resistant M. genitalium. All three kits can be used both for epidemiological monitoring of M. genitalium presence and mutation prevalence estimation. In Moscow, macrolide- and fluoroquinolone-resistant mutant prevalence increased in 3.9 and 2.7 times in 3 years.

The article presents the experience of the city children's polyclinic No. 133 of the Moscow Department of Health in a difficult epidemiological situation associated with a new infection COVID-19. A description of the stages of the organizational work of a polyclinic in a pandemic is given, including such areas as: a) conducting lectures and webinars for doctors and nurses of a medical organization, introducing recommended methods for diagnosing and treating COVID-19, creating and observing conditions for the personal safety of employees; b) the formation of tools and a database for analytical work; creation of registers of patients and employees of the polyclinic in order to monitor and evaluate the effectiveness of work; characteristics of the structures of age-specific morbidity in children who have undergone a new coronavirus infection and community-acquired pneumonia with substantiated confirmation for them of compulsory dispensary observation and rehabilitation measures; description of the development of routing of healthy and sick children, operational identification and continuous analysis of difficulties in the work of the polyclinic during this period; c) the formation of distance technologies in treatment and prophylactic work with patients, organized group and individual exercise therapy classes, including respiratory rehabilitation gymnastics for children who have undergone a new coronavirus infection; development of an organizational algorithm for the formation of medical and nursing teams for visiting patients with COVID-19 at home and individual teams for visiting patients for patronage. The organization of this treatment and prophylactic work was approved and a confirmation was received from the Ministry of Health of the Russian Federation of the right to replicate the experience gained from the work of the polyclinic in the conditions of COVID-19.

It is known that the oral cavity is an epidemiological hazard due to the high level of viral and bacterial contamination. Despite the narrow specialization and distant connection with the problem of viral pneumonia, dentists, nevertheless, are at risk of contracting the new coronavirus infection COVID-19. To reduce the epidemiological activity the provision of routine dental care was suspended in the vast majority of regions of the Russian Federation including the Moscow region, from the end of March 2020 to June 20, 2020. During the entire period of routine medical care suspended, the Moscow region chief dentist's team was daily monitoring information about applied patients. The suspension of routine medical care has reduced the number of cases of COVID-19 infection contact transmission in medical organizations during the period of the most active increase in the morbidity. In addition, the decrease in the number of patients enabled medical organizations to reduce the number of medical personnel, which contributed to a decrease in the percentage of morbidity among doctors.

About 30% of male infertility is associated with genetic abnormalities. Genetic polymorphisms increase the level of individual susceptibility to adverse environmental factors and affect human reproductive function., Aim: To study associations of glutathione S-transferase GSTP1(Ile/Val) gene polymorphisms (A313G; rs1695) with the risk of pathospermia in men of the Moscow region., Materials and Methods: We examined 138 men in the Moscow region (n=70 - proven pathospermia, n=68 - fertile men). We obtained genomic DNA from blood leukocytes and studied the gene polymorphisms of glutathione-S-transferase GSTP1 (Ile/Val) (A313G; rs1695) in real time., Results: In the analysis of the distribution frequencies of polymorphisms GSTP1 (Ile/Val) (A>G rs1695), we revealed the predominance of the AA genotype in fertile men and the predominance of the GG genotype (homozygous minor allele) in men with pathospermia. However, we found no significant difference in these parameters between the compared groups of patients (p=0.344). For GSTP1 (Ile/Val) polymorphism (A313G, rs1695), significant differences in the distribution of genotype frequencies in the subgroup of men with teratospermia (2=7.00; p=0.03) were revealed. The frequency of allele G in the subgroup of men with teratospermia is statistically significantly different from the frequencies of alleles in the control group: 52% versus 30% (2=10,004; p=0.0015). In subgroups of men with azoospermia and asthenospermia, we did not find significant differences in the distribution of genotypes of GSTP1 polymorphism (rs1695) (p>0.05)., Discussion: Glutathione-S-transferase (GSTP1) is a multifunctional protein that protects sperm cells from the damaging effects of reactive oxygen species and xenobiotics. The Association of GSTP1 polymorphism (Ile/Val) (A313G, rs1695) with teratospermia explains the main stages of the pathogenesis of male infertility in this category of patients., Conclusion: Gene polymorphism GSTP1 (A313G, rs1695) can be considered a genetic marker of susceptibility to pathospermia in men.

Aim        To analyze first results of using the Aterostop calculator for a comprehensive evaluation of the risk for cardiovascular diseases (CVD).Material and methods        A cross-sectional study analyzed major and additional risk factors in 460 subjects without apparent disease and in patients with documented CVD of atherosclerotic origin using the application (calculator) Aterostop developed in the National Medical Research Center of Cardiology in Moscow, Russia.Results   45.4% of evaluated persons belonged to the categories of very high and extreme risk. Age and frequencies of smoking, arterial hypertension, and diabetes mellitus (DM) increased with the increase in risk; the growth of DM was exponential. 129 (28%) individuals used lipid-lowering medications at the time of study. Their plasma levels of low-density lipoprotein cholesterol (LDL-C) were significantly lower than in those who did not received this treatment. However, achieving the target level was inversely proportional to the risk: the greatest proportion of individuals who reached the LDL-C target was in the category of low risk and the smallest proportion was in the category of extreme risk (75 % vs. 3.7 %, respectively).Conclusion            The results obtained with the calculator Aterostop were consistent with earlier reports of insufficient effectiveness of primary and secondary prevention of atherosclerotic CVDs, which requires more tight and fruitful cooperation of the physician and the patient.

The article presents the dynamics of disability due to cerebrovascular diseases in 2014-2018 in Moscow. The age gender analysis of the disabled in this category was carried out. It was established that 30% of total population of the disabled due to cerebrovascular diseases accounted for the share of those who were recognized as disabled for the first time in the structure of total population. The most frequently disabled persons are those who are older than able-bodied age. In total structure of the disabled due to cerebrovascular diseases, women predominate.

To preserve the country's population is among one of the most vital tasks over the period of existence of the new Russia and constitutes the subject of national security. The article presents the results of analysis of population mortality rate of the Russian Federation, the Central Federal Okrug and City of Moscow during the first eight months of 2020 towards to concurrent period of 2019. In January-March 2020, the population total mortality rate, retaining prevalent trends of number of preceding years, decreased in the Russian Federation by 3.8%, in the Central Federal Okrug by 3.0% and in City of Moscow by 3.9%. However, since April-May the situation has changed dramatically and, according to the results of January-August, mortality by this time has increased, and its growth made up to 6.5% in the Russian Federation, 7.8% in the Central Federal Okrug and 15.6% in the City of Moscow. In May 2020, the gain of absolute number of the deceased in the Russian Federation by months (towards to concurrent month of 2019) made up to 11.9%, in June to 18.6%, in July to 19.7% and in August to 9.6%. In Moscow, the peak values of this increase were noted in May - 57.2% and in June - 41.6% In the conditions of new coronavirus infection pandemic, the share of COVID-19, as main cause of death (ICD-10 codes U07.1 and U07.2), in the structure of total mortality in April-August consisted 3.2% and in the structure of excess deaths in May-August - 28.6%. The increase of mortality and continued decrease of birth rate resulted in increasing of natural population loss by 1.5 times and more and reached such values as -3.6 in the Russian Federation, -4.9 in the Central Federal Okrug and -1.6 in the City of Moscow (per 1000 of population). The process of depopulation of the Russian nation not only retained, but significantly has become significantly aggravated.

Background: In Russia, cardiovascular disease (CVD) mortality is high and the mortality gap between men and women is large. Conventional risk factors cannot explain these phenomena. Ventricular arrhythmia (VA) is an important contributor to the death toll in community-based populations. The study examines the prevalence and the mortality impacts of VA in men and women and the role of VA in the male mortality excess at older ages., Methods: This is a secondary analysis of data from the Stress, Aging, and Health in Russia (SAHR) study that was fielded in 2007-9 in Moscow (1800 individuals, mean age 68.8 years), with mean mortality follow-up of 7.4 years (416 deaths, 248 CVD deaths). Indicators reflecting the frequency and the complexity of VA were derived from 24-h ambulatory ECG recordings. Other covariates were: socio-demographic characteristics, conventional risk factors, markers of inflammation, reported myocardial infarction, and stroke. The impacts of VA and other variables on CVD and all-cause mortality among men and women were estimated with the proportional hazard models. We assessed the contributions of VAs to the male-female mortality gap using hazard models that do and do not include groups of the predictors. Logistic models were used to assess the associations between VA and other biomarkers., Results: VAs were about twice as prevalent among men as among women. In both sexes, they were significantly associated with CVD and all-cause mortality independently of conventional risk factors. The highest hazard ratios (HRs) for CVD death were found for the runs of ventricular premature complexes (VPCs) HR = 2.45, 95% CI 1.63-3.68 for men and 2.75, 95% CI 1.18-6.40 for women. The mortality impacts of the polymorphic VPCs were significant among men only (HR = 1.50, 95% CI 1.08-2.07). VA indicators can potentially explain 12.3% and 9.1% of the male-female gaps in mortality from CVD and all causes, respectively. VAs were associated with ECG-registered ischemic problems and reported MI, particularly among men., Conclusions: VA indicators predicted mortality in older Muscovites independently of other risk factors, and have the potential to explain a non-trivial share of the excess male mortality. The latter may be related to more severe coronary problems in men compared to women.

Objectives: Due to the maternally-inherited nature of mitochondrial DNA (mtDNA), there is a lack of information regarding fetal mtDNA in the plasma of pregnant women. We aim to explore the presence and topologic forms of circulating fetal and maternal mtDNA molecules in surrogate pregnancies., Methods: Genotypic differences between fetal and surrogate maternal mtDNA were used to identify the fetal and maternal mtDNA molecules in plasma. Plasma samples were obtained from the surrogate pregnant mothers. Using cleavage-end signatures of BfaI restriction enzyme, linear and circular mtDNA molecules in maternal plasma could be differentiated., Results: Fetal-derived mtDNA molecules were mainly linear (median: 88%; range: 80%-96%), whereas approximately half of the maternal-derived mtDNA molecules were circular (median: 51%; range: 42%-60%). The fetal DNA fraction of linear mtDNA was lower (median absolute difference: 9.8%; range: 1.1%-27%) than that of nuclear DNA (median: 20%; range: 9.7%-35%). The fetal-derived linear mtDNA molecules were shorter than the maternal-derived ones., Conclusion: Fetal mtDNA is present in maternal plasma, and consists mainly of linear molecules. Surrogate pregnancies represent a valuable clinical scenario for exploring the biology and potential clinical applications of circulating mtDNA, for example, for pregnancies conceived following mitochondrial replacement therapy., (© 2020 The Authors.

The results of the analysis of primary disability due to thyroid cancer of the adult population of Moscow in the period 2015-2019 are presented. An increase in the number of peaple newly recognized as disabled (PNRD) due to this pathology was revealed. In the age structure of primary disability elderly people was dominated. The predominant gender contingent of the PNRD were women. It was found that the predominant number of PNRD had a moderate impairment (II degree) of the basic functions of the body. At the same time, gender differentiation in the severity of persistent impairment of the body functions among disabled was revealed. In the contingent of disabled men the proportion of persons with severe (III degree) and complete (IV degree) impairment of the function of the blood system and the immune system and with a severe impairment of the function of the endocrine system and metabolism was higher compared to the contingent of disabled women. It was determined that the main types of capacity limitations were self-care, work, moving and communicate limitations (the first degree of difficulties in life areas prevailed (p<0,05). Thyroid cancer, due to the rapid growth of morbidity and disability, is an important public health concern. The study of disability indicators of the population is necessary for the development of rational measures of medical and social rehabilitation of patients suffering from thyroid cancer, and for the implementation of medical and social prevention of disability.

Objective: To study the features of the formation of gender reassignment`s ideas in schizophrenia spectrum disorders and to differentiate diagnosis of these psychopathological formations with transsexualism., Material and Methods: The study was carried out in the Department of Sexology and Therapy of Sexual Dysfunctions of the Moscow Research Institute of Psychiatry - a branch of the Serbsky National Medical Research Center for Psychiatry and Narcology in the period from October 2018 to May 2020. The study included 100 outpatients referred for gender reassignment. The subjects were divided into two groups. The first group consisted of 58 patients with schizophrenia spectrum disorders (Paranoid schizophrenia, F20.0; Schizotypal disorder, F21; Chronic delusional disorders, F22) with ideas of sex change. The second group included 42 patients with a diagnosis of «Transsexualism» (F64.0). Clinical-psychopathological, pathopsychological and statistical methods were used., Results: Patients with transsexualism are statistically significantly more often adapted in terms of work and family, have experience of life in the desired gender, use hormone therapy and gender-affirmative interventions before undergoing a medical commission on gender reassignment and less often hospitalized in psychiatric hospitals, compared to patients with schizophrenia spectrum disorders ( p <0.05). Patients with schizophrenia are more likely to experience delays and disharmony in psychosexual development. Sex reassignment ideas are more common in schizotypal disorder than in other types of schizophrenia., Conclusion: Ideas of gender reassignment in schizophrenia spectrum disorders, as a rule, are formed on the basis of existing deviations in the early stages of the formation of gender identity. The central place in the psychopathology of schizophrenia spectrum disorders with ideas of gender reassignment is occupied by depersonalization-dysmorphophobic experiences with the following formation of overvalued, delusional or paranoid ideas of sex reassignment.

Objective: To analyze the development of surgical approaches for hepatic echinococcosis., Material and Methods: We have analyzed diagnosis and treatment of 349 patients with liver echinococcosis; 97 patients were treated at the Botkin Clinical Hospital for the period from 2009 to 2019 and 252 patients were treated in surgical hospitals of Moscow city for the period from 2014 to 2019., Results: General and specific postoperative complications, relapses and surgical approaches were assessed. The number of echinococcectomies performed in surgical hospitals of Moscow is 3 times higher compared to the Botkin Hospital. The number of liver resections is comparable in both groups. The number of pericystectomies is more than 2 times higher in the Botkin Hospital. PAIR technique was more common in surgical hospitals of Moscow., Conclusion: Evolution of surgical treatment from open echinococcectomy to anatomical liver resections and subsequent pericystectomy with PAIR technique becomes another round of evolutionary spiral in the development of surgical treatment of liver echinococcosis.

The spinal muscular atrophy is neuromuscular disease caused by mutations in SMN1 gene. The clinical picture of disease is characterized by progressive muscular weakness and atrophy associated with degeneration of spine, and in severe cases by affection of motor neurons of lower bulbar cells. The spinal muscular atrophy progressing course resulting in disability and infant mortality. Actually, specific treatment is at the stage of clinical trials. However, patients are needed in permanent symptomatic arresting of manifestations and pathogenetic treatment preventing development of disease. The article presents calculations of direct medical costs for treatment in pediatric patients (0-17 years old) in Moscow with the main types of spinal muscular atrophy. It is established that the cost of specialized medical care of children with spinal muscular atrophy per single under age patient in Moscow consisted 7,131,185.84 rubles annually, including primary diagnostic, treatment and rehabilitation and medicinal treatment. In total, according to data for 2020 in Moscow, where number of children patients is 144, the cost of specialized medical care of children with spinal muscular atrophy is estimated as 1,024,580,269.16 rubles. At that, data takes into account only direct medical costs for out-patient and in-patient care of children with spinal muscular atrophy, excluding number of exacerbations of disease. Taking into account average numbers of hospitalizations per year because of illness, the cost of in-patient care of single child amounts to 7,844,304.42 rubles annually and 1,127,018,732.08 rubles for all children with spinal muscular atrophy in Moscow (according data of 2020).

Epistaxis or nosebleeds (NB) are the most common emergency pathology that otorhinolaryngologists have to deal with. Purpose of the work: to study the prevalence of patients with NB in the otorhinolaryngological departments of hospitals in Moscow from 2003 to 2019. The reports of the heads of the ENT departments of the city clinical hospitals in Moscow were studied. Inclusion criteria were hospitals working with an adult contingent of patients. An approximation analysis was carried out and trend indicators of the prevalence of NB were studied., Results: 2003 to 2019 the total number of patients treated in ENT hospitals was 563 189 people, 20 623 (3.7%) patients were treated with NB, of which 52 (0.25%) died. The average age of the deceased was 64.7 years, men are 73.7% more prevalent than women. In 96.2% of patients, epistaxis was a complication of the underlying disease, and in 3.8%, it was regarded as a concomitant condition. In 30.8% of the deceased, NB recurred with the background of malignant lesions of the nose and nasopharynx, in 69.2% - posthemorrhagic anemia aggravated diseases of other organs and systems. Over the past 17 years, there has been a tendency for the growth of treated patients with diseases of ENT organs and patients with nosebleeds by 58.5% and 51.1%, respectively. The studied approximation of the relative prevalence and mortality rates in patients with NB showed that for the period from 2003 to 2019. trend values are practically at the same level with the minimum multidirectional linear dynamics - -0.24% and +0.04%, respectively.

Obesity is one of the most important and actual problems of public health, of healthcare, which dramatically expanded through the latest four decades. The aim of the study was the analysis of physical conditions of Moscow preschoolers at the beginning of 21th century as the indicator of nutritional status in «obesogenic» environment of megalopolis. Material and methods . Complex anthropometric study of children attending kinder gardens in Moscow (aged 3-7 years) was held in 2005-2006 (n=759). Literature data on samples of the 1970s were used for comparison. Anthropometric measurements were used to calculate personal values of body mass index (BMI, kg/m 2 ). The more detailed estimation of somatic specificity of children included calculation of average values of standardized differences of each single body dimension of material of 2005-2006 from the values of samples of the 1970s. Results and discussion. The distribution of BMI of Moscow preschoolers at the beginning of 21th century (13.6% were overweight and 7.5% were obese) is quite comparable to the results of other population studies in Russia and around the world. The circumferences, mediated by adipose tissue, and skinfolds of modern Moscow preschoolers showed very significant increase of average standardized levels of dimensions (0.9-1.1 standard deviations as compared to the data of the 1970s). The comparison with the results of the similar study of Moscow school children allows, probably, to speak about the existence of accumulation effect as the mechanism of obesity development in the age aspect. Conclusion . The effect of the significant and valid increase of adiposity in preschoolers, combined with very modest changes of the size and shape of skeletal/muscle system and even its relative weakening was shown based on the results of the survey of Moscow preschoolers, conducted in 2005-2006, in comparison with the series of the 1970s., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)

Purpose of the Study: The purpose is to study the spectrum of bacterial pathogens that cause acute purulent otitis media (APOM) in children of the Moscow region in modern conditions and assess their sensitivity to the main groups of antibiotics., Material and Methods: The study included 1.864 children who underwent examination and received treatment in the otorhinolaryngological department of Morozovskaya Pediatric Municipal Clinical Hospital in the period from 01 July 2018 to 31 June 2020 with a diagnosis of APOM., Results: The study showed that the leading bacterial pathogens of APOM are Streptococcus pneumoniae (28.0%), Staphylococcus aureus (27.2%), Streptococcus pyogenes (22.2%), Haemophilus influenzae (7.8%), and Pseudomonas aeruginosa (6.5%). Attention is drawn to the increase in the level of resistance of S. pneumoniae to oxacillin (11.64%)., Conclusions: The data obtained indicate the feasibility and prospects of vaccination against pneumococcal infection as one of the ways to curb the spread of resistance of S. pneumoniae to antibacterial drugs.

The purpose of the study was to analyze the types and volumes of treatment and prophylactic services provided to the adult population with infectious diseases in the dental office of a multidisciplinary hospital., Materials and Methods: The types and volumes of dental care provided to the adult population with infectious diseases in a multidisciplinary hospital have been analyzed., Results: The study showed that dentists use 49 types of services when treating adults with infectious diseases, which corresponds to 29.88% of the compulsory medical insurance classifier in Moscow. Provided services can be conditionally divided into 4 groups: consultation, diagnostic, preventive and medicinal manipulations. The share of consulting services corresponds to 18.16±0.41% of the total volume of services provided; on average patients made 320.8 visits to the dentist's doctors per year, which corresponds to 2.38 visits for each patient. The proportion of medicinal manipulations, diagnostic and preventive services corresponds to 68.64±0.49%, 7.02±0.27% and 6.17±0.26%, respectively. Services related to the diagnosis and treatment of diseases of the oral mucosa and salivary glands dominate with 69.3%, on average 5.51 services are provided per visit., Conclusion: The compulsory medical insurance program for the city of Moscow should provide services for the diagnosis, treatment and prevention of dental diseases, provided by doctors specializing in «dentistry», for patients with infectious diseases who are undergoing treatment in inpatient conditions.

Aim: To compare dental and psychological status in athletes of Olympic teams and the population of Moscow., Materials and Methods: In order to study the features of the dental rehabilitation of Olympic athletes, a comparative study of the dental and psychological status of 132 athletes was carried out when they were included in the Olympic teams and 104 residents of Moscow of the same age. Clinical x-ray examination was supplemented by «Hamburg testing» of the masticatory apparatus and psychological examination using common questionnaires and scales., Results: The study revealed a difference in the status of dental status, the results of the "Hamburg Testing" and psychological examination between athletes of the Olympic reserve and the population of Moscow of the same age. Athletes showed a lower quality of previous treatment of caries and its complications, insufficient oral hygiene, more frequent detection of chronic periodontitis, diseases of the oral mucosa, secondary deformations of the dentition, pathological phenomena of the temporomandibular joint, masticatory apparatus dysfunction according to the results of the "Hamburg Testing". Athletes also established psychological status features: higher rates of reactive and personal anxiety, the presence of depressive manifestations, lower quality of sleep and quality of life., Conclusion: The revealed patterns can provoke muscle hyper-tone and muscular-articular dysfunction of the maxillofacial region, which must be taken into account during the dental rehabilitation of athletes of Olympic teams.

Objective: To study the prevalence of somatic diseases in patients with mental disorders based on the results of medical examination in Moscow mental health clinics in 2018., Material and Methods: A retrospective analysis of the results of the clinical examinations of 6492 outpatients, which accounted for 79.5% of patients who underwent medical examination in this time period., Results: Comorbid somatic diseases were found in 4883 (75%) patients. Hypertension and non-insulin-dependent diabetes mellitus were most frequent with the prevalence higher than in the general population of the Russian Federation. Patients with diagnosed schizophrenia, along with hypertension and diabetes mellitus, have found to be at increased risk of diseases of the endocrine system and metabolic disorders. The incidence of the mentioned diseases is not higher than that reported in literature., Conclusion: The higher prevalence of socially relevant diseases (hypertension, diabetes mellitus) among patients with mental disorders demands the development of strategies for prevention, early detection and treatment of these diseases in psychiatric patients.

Aim: In a retrospective study, we evaluated factors associated with the early development of septic shock in patients with severe COVID-19., Materials and Methods: We collected medical records of the intensive care unit patients submitted by the local COVID-19 hospitals across Russia to the Federal Center for the Critical Care at the Sechenov First Moscow State Medical University (Sechenov University). Septic shock in crticially ill patients requiring mechanical ventilation was defined as a need in vasopressors to maintain blood pressure., Results: We studied 1078 patients with severe COVID-19 who were admitted to the intensive care units for respiratory support. There were 611 males and 467 females. The mean age was 61.013.7 years. Five hundred twenty five medical records (48.7%) were received from the Moscow hospitals, 159 (14.7%) from the Moscow region, and 394 (36.5%) from the hospitals located in 58 regions of the Russian Federation. In 613 (56.9%) patients, diagnosis of SARS-CoV-2 infection was confirmed by PCR, and in the other cases it was established on the basis of the clinical picture and the results of the chest CT scan. Septic shock developed in 214 (19.9%) of 1078 patients. In the logistic regression model, the risk of septic shock in patients older than 50 years was higher than in patients of a younger age (OR 2.34; 95% CI 1.533.67; p0.0001). In patients with more severe SARS-CoV-2 infection, there was an increase in the prevalence of cardiovascular diseases, including coronary heart disease and atrial fibrillation, type 2 diabetes and malignant tumors. The risk of septic shock in patients with three or more concomitant diseases was higher than in patients without any concomitant chronic diseases (OR 1.76; 95% CI 1.762.70)., Conclusion: The risk of septic shock in patients with acute respiratory distress syndrome induced by SARS-CoV-2 is higher in patients older than 50 years with concomitant diseases, although a severe course of the disease is also possible in younger patients without any concomitant disorders.

Aim: To present the results of work of National Medical Research Center of Treatment and Rehabilitation, reassigned for COVID-19 patients treatment during pandemic. Run-up methodology, procedures and working process organization are detailed., Materials and Methods: 354 COVID-19 patients were treated from 13.04.2020 to 10.06.2020 [age 59 (470) years, 56% women, body mass index 28.5 (24.932.2) kg/m2]. Patients were admitted at 8 (611) day of sickness. In-hospital stay was 16 (1420) days., Results: NEWS scale at the day of admittance was 2 (14); 2 (13) in patients discharged alive and 6 (47) in died patients, p=0.0001. So prognostic accuracy of NEWS scale was confirmed as very well (area under ROC-curve = 0.819). 69 patients (19.5%) were treated at intensive care department for 7 (413) days. 13 patients died, 11 of them had COVID-19 as direct or indirect cause of death. Total in-hospital mortality was 3.67%, in-hospital mortality of COVID-19 patients 3.1%. 17 healthcare workers (HCW), contacted with COVID-19 patients were infected (2.67%). 4 HCW, who had no direct contact with patients were also infected and 7 HCW were infected before the first patient was admitted. No one of them died., Conclusion: Complex tasks of healthcare organization during COVID-19 pandemic can be solved quickly with acceptable quality, characterized by low levels of patients; mortality and HCW infection.

Background: The prevalence of T2DM is steadily increasing not only among the elderly, but also at a young age. T2DM is preceded by a long period of significant metabolic changes with the development of insulin resistance and в-cell dysfunction. To reduce the prevalence of complications, treatment is needed which affects several pathophysiological mechanisms underlying the disease. Monotherapy with metformin at the onset of T2DM is often insufficient. The VERIFY study demonstrated the advantage of early administration of a combination of vildagliptin and metformin in relation to the glycemic durability compared to the sequential intensification of metformin with vildagliptin in patients with type 2 diabetes., Aims: To assess the current situation in terms of the incidence of T2DM complications and the structure of the prescribing glucose lowering drugs based on the data from the Diabetes Register (DR) of the Moscow Region. To demonstrate the advantages of early combination therapy in patients with newly diagnosed T2DM using clinical cases., Materials and Methods: The data from the DR of the Moscow region, which is part of the National Diabetes Register of the Russian Federation, were used for the analysis. The data of 6,096 patients with T2DM who died in 2019 were evaluated for building the structure of the causes of death of patients with T2DM. The pattern of glucose-lowering therapy was analyzed based on data of 226,327 patients with T2DM (for 2020), as well as separately of 14,379 patients with newly diagnosed T2DM in 2019. Clinical cases are described based on the data of two patients with T2DM, available in the DR database and outpatient records., Results: In patients with young onset T2DM (&lt;40 years), the prevalence of severe complications is higher than in the general population of patients with T2DM: blindness is in 5.9 times, end-stage chronic renal failure in 2.9 times, lower limb amputations in 6.4 times more. When prescribing glucose lowering drugs, monotherapy is prevalent, mostly metformin. In double combination, metformin is used in 96.22% of cases. In the structure of glucose lowering drugs, with newly diagnosed T2DM, combination therapy is used less frequently than in patients with T2DM in general. Of the drugs of the IDP-4 group, vildagliptin is most often prescribed - 46.25% (including of a fixed combination with metformin - 12.22%). Clinical cases reflect a rapid clinical outcome: a decrease in HbA1c to the target in 6 months, the absence of hypoglycemia or other side effects, and positive weight dynamics., Conclusions: A fairly large propotion of patients with T2DM are on monotherapy with glucouse lowering drugs. Early prescription of the combination of metformin plus vildagliptin provides a longer maintenance of glycemic control without increasing the risk of hypoglycemia and weight gain for patients with newly diagnosed T2DM.

Aim      To study changes in markers for myocardial direct injury and dysfunction and endothelial dysfunction (ED) indexes in patients with indolent lymphoma during the antitumor treatment.Material and methods  Current antitumor therapy for lymphoma is often associated with cardio- and vasculotoxicity, studying of which is a relevant scientific direction. Markers for myocardial direct injury and dysfunction and ED indexes were studied in patients with indolent lymphomas receiving polychemotherapy (PCT). The study included 77 patients with newly diagnosed indolent type lymphoma. The main group (n=52): mean age, 63.4±2.8 years, 15 (28.8 %) men who had received one course of PCT. The comparison group (n=25): mean age, 61.8±3.7 years, 8 (32 %) men who had not received PCT. Troponin I (TnI), high-sensitivity troponin I (hs-сTnI), heart-type fatty acid binding protein (h-FAВР), and N-terminal pro-B-type natriuretic peptide (NT-prоBNP) were measured in patients of both groups. ED was evaluated by measuring the level of vascular cell adhesion molecule (VCAM) and by assessing the structure and function condition of small blood vessels using photoplethysmography. In both groups, the study parameters were determined at the start of the study (T1) and following the PCT course in the main group; if the PCT schedule included anthracycline antibiotics, the second point (T2) was assessed at 6 h following the drug administration.Results In both groups, the level of NT-proBNP was increased. This increase was significantly more pronounced in the comparison group (49.896±23.228 vs 20.877±8.534 pmol/l, respectively, p=0.011) whereas a tendency to its increase was observed after the PCT course. Before the start of the treatment, laboratory and instrumental signs of ED were noticed: the level of VCAM was 4951±1297 and 3225±757 ng/ml in the comparison group and the main group, respectively (р=0.246); reflection index was &lt;1.8 in 23 (44.2%) patients of the main group and in 16 (64%) patients of the comparison group (р=0.098). During the PTC course, the endothelial function significantly improved; the level of VCAM decreased by 748 ng/ml (p=0.016), which was associated with significant decreases in erythrocyte sedimentation rate by 2.71 mm/h (р=0.027) and lactate dehydrogenase level by 62.38 U/l (р=0.026). Statistically significant decreases in other inflammatory markers (alpha-2-globulin, fibrinogen, C-reactive protein, neutrophil count) were not observed.Conclusion      The level of NT-proBNP showed the highest sensitivity in assessing the cardiotoxic effect of PCT. The dynamics of VCAM level suggested a possible role of the disease itself in the development of ED in this patient group.

To estimate the prevalence and factors associated with HIV and five other STIs among outdoor female sex workers (OSFW) and indoor FSW (IFSW)., Methods: Cross-sectional survey using respondent-driven sampling methodology. Participants answered a bio-behavioural questionnaire and were tested for Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Trichomonas vaginalis (TV), syphilis (lifetime contact) and Mycoplasma genitalium (MG). Weighted HIV and other STIs prevalence and 95% CIs were calculated. Weighted multivariate logistic regression was performed to identify factors associated with having at least one STI (including HIV)., Results: Between October 2017 and July 2018, 385 FSW participants were recruited, among whom 206 (53.5%) were IFSW and 179 (46.5%) were OFSW. The mean age was 31.4 years. Weighted HIV prevalence was 3.1% (95% CI 1.5 to 7.0). Weighted prevalence of other STIs was: 4.1% (95% CI 2.2 to 8.0) for NG, 8.8% (95% CI 5.9 to 13.0) for CT, 12.7% (95% CI 8.6 to 18.0) for TV, 13.9% (95% CI 9.9 to 19.0) for syphilis (lifetime contact) and 14.9% (95% CI 10.5 to 21.0) for MG. STI prevalence was significantly higher among OFSW for CT, TV and MG (p<0.001). In total, 43.2% of the participants had at least one HIV/STI. Factors associated with having HIV/STI were being an OFSW (OR 3.29; 95% CI 1.72 to 6.27); being registered in another Russian region (2.61 (95% CI 1.05 to 6.48)); having never been tested for HIV (2.51 (95% CI 0.98 to 6.41)) and having a low level of knowledge regarding HIV transmission (4.88 (95% CI 0.96 to 24.78))., Conclusion: Prevalence of HIV and STIs was high among FSW in Moscow. OFSW were more vulnerable to STIs. There is an urgent need to tailor programmes for sexual and reproductive health for FSW in Russia., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Introduction: Measles remains an urgent problem in Russian healthcare. Despite the ongoing vaccination, there is an increase in the incidence of measles. Prevention of measles is particularly important in high-risk groups, as well as among healthcare professionals to prevent hospital-acquired outbreaks of infection. The duration of post-vaccination immunity during the elimination of measles has not been sufficiently studied, so often people who  have had measles in childhood or have 1-2 vaccinations against the disease lose their protective antibodies with age in the absence of natural boosterization.Goals and objectives. To study the intensity of specific immunity to measles in employees of the maternity unit., Material and Methods: The study involved 271 employees of the maternity unit aged 21 to 93 years (262 serum samples). The level of IgG antibodies (Ab) to the measles virus in the blood serum was studied by ELISA using a standard set of reagents for the quantitative determination of IgG by «VECTOR-BEST». The result was  considered negative if the concentration of IgG to the measles virus in tested sample was ≤ 0.18 IU/ml and  positive - if &gt; 0.18 IU/ml. Results. The number of seronegatives ranged from 0% to 30.8% in female employees with its maximum at age of 31-35 years. The lowest proportion of seronegative and the highest proportion of seropositive women were observed among the elderly, &gt; 60 years., Discussion: There is a marked tendency for an increase of the proportion of persons with average Ab levels with age and a decrease of the proportion of persons with low Ab levels. The percentage of seronegative women among employees exceeded the recommended level, which makes it possible for an nosocomial outbreak when an infection is introduced., Conclusion: The authors recommend that serological testing for the intensity of the immune response against measles should be included in the standard of the pre-vaccination screening for adults.

Introduction: The novel SARS-CoV-2 coronavirus, which emerged at the end of 2019 and caused a worldwide pandemic, triggered numerous questions about the epidemiology of the novel COVID-19 disease and  about wellknown coronavirus infections, which used to be given little attention due to their mild symptoms., The Purpose: The routine screening-based multiyear retrospective observational study of prevalence and circulation patterns of epidemic-prone human coronaviruses in Moscow., Material and Methods: The real-time polymerase chain reaction was used to detect RNA of human coronaviruses (HCoVs) in nasal and throat swabs from 16,511 patients with an acute respiratory infection (ARI), aged 1 month to 95 years (children accounted for 58.3%) from January 2016 to March 2020, and swabs from 505 relatively healthy children in 2008, 2010 and 2011. Results. HCoVs were yearly found in 2.6-6.1% of the examined patients; the detection frequency was statistically higher in adults than in children, regardless of sex. At the height of the disease incidence in December 2019, HCoVs were detected in 13.7% of the examined, demonstrating a two-fold increase as compared to the multi-year average for that month. The statistical frequency of HCoV detection in ARI pediatric patients under 6 years was significantly higher than in their healthy peers (3.7 vs 0.7%, p = 0.008)., Conclusion: HCoVs circulate annually, demonstrating a winter-spring seasonal activity pattern in the Moscow Region and reaching peak levels in December. Over the years of observation, the HCoV epidemic activity reached maximum levels in December 2019-February 2020 and decreased in March to the multi-year average. Amid a growing number of SARS-CoV-2 cases imported to Moscow in March 2020, the HCoV detection frequency dropped sharply, which can be explained by the competition between different coronaviruses and by the specificity of HCoV detection with the diagnostic test kit used in this study.

The article discusses results of complex cross-sectional and anthropometric medical check up in the M. V. Lomonosov Moscow State University in 2002-2003 and 2013. The sampling covered 494 students aged 18-23 years. The check up included basic anthropometric measurements and cardiovascular parameters. The pulse pressure and Bayevsky adaptation potential were calculated. Results. The secular trend in body mass increasing was established. So, decade variations was +3.3 kg in young men (p=0.021) and +1.8 kg in girls (p=0.098). The cardiovascular system parameters degraded over ten years: occurrence of bradycardia and tachycardia increased significantly for both genders. In most observed participants in 2002-2003 the sufficient adaptation according Bayevsky was established (75.1% in young men and 71.6% in girls). Over ten years, this proportion decreased to 44.1% in young men (p=0.0000) and to 51.7% in girls (p=0.034). The percentage of adaptation failure cases increased. Conclusions. The analysis of decade dynamics demonstrated deterioration of physical development and somatic health parameters of modern youth. The established trends should be considered in planning health improving programs targeted to early prevention of cardiovascular diseases and development of adaptive capabilities of modern youth.

There is currently an increase in the number of heat waves occurring worldwide. Moscow experienced the effects of an extreme heat wave in 2010, which resulted in more than 10,000 extra deaths and significant economic damage. This study conducted a comprehensive assessment of the social risks existing during the occurrence of heat waves and allowed us to identify the spatial heterogeneity of the city in terms of thermal risk and the consequences for public health. Using a detailed simulation of the meteorological regime based on the COSMO-CLM regional climate model and the physiologically equivalent temperature (PET), a spatial assessment of thermal stress in the summer of 2010 was carried out. Based on statistical data, the components of social risk (vulnerabilities and adaptive capacity of the population) were calculated and mapped. We also performed an analysis of their changes in 2010-2017. A significant differentiation of the territory of Moscow has been revealed in terms of the thermal stress and vulnerability of the population to heat waves. The spatial pattern of thermal stress agrees quite well with the excess deaths observed during the period from July to August 2010. The identified negative trend of increasing vulnerability of the population has grown in most districts of Moscow. The adaptive capacity has been reduced in most of Moscow. The growth of adaptive capacity mainly affects the most prosperous areas of the city., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Accuracy of statistical registration of mortality in Russia, especially in times of crisis, is a pressing and relevant issue; this problem was challenging Moscow in the 2000s: until recently, the capital was a complete outsider in terms of accuracy of statistical registration of mortality. The purpose of the study was to identify peculiar features of evolution and the structure of mortality from an event of undetermined intent among Moscow working-age population in the 2000s against the background of the processes taking place in Russia. The article analyzes mortality from an event of undetermined intent among Moscow population of young and old working age in the 2000s, as well as its nosological aspects in 2011-2018, when certain events of undetermined intent were separated as individual nosological units. A sharp decline in indicators in 1999-2000 and their growth in 2015-2017 have been identified. It is shown that these shifts were due to all leading events of undetermined intent (falls/jumps from a high place, hanging/strangulation/suffocation, medicament, alcohol and drug poisoning as well as specified and unspecified events). As a result, the structure of mortality after 2015 has significantly changed due to a sharp increase in the significance of alcohol, medicament and especially drug poisoning. It should be emphasized that in the 2010s the significance of latent suicide in all age and gender groups of Moscow working-age population is significantly higher than in Russia.

Prevention of strokes and the fight against their consequences require not only the work of the healthcare system, but also the self-preserving behavior of the population, which is largely motivated by competence in this sphere. The study of public awareness on this issue and the development of recommendations on information policy were the main objectives of the study. In October-December 2019 two surveys were conducted in Moscow, the sample of each was 800 people. The study found an increase between the waves in the number of those who think they know the signs of a stroke (up to 65%). Despite the mainly correct answers, this self-evaluation is not always backed-up by real knowledge: e.g. a stroke was sometimes confused with an ischemic heart disease, a heart attack and epilepsy. Less competency is demonstrated by men and people with primary/secondary education, younger respondents. 94% of the respondents will call an ambulance when they see signs of a stroke, 16% will begin to provide assistance on their own, and in general their actions will be correct, although there are a number of misconceptions. Among the main risk factors of a stroke the respondents consider bad habits. The population receives information about signs of a stroke mainly from relatives/friends (25%) and on the Internet (22%). The study found necessity for the right information about strokes. There is a need for some greater presentation of peer-reviewed information materials in the information field.

The purpose of the study is to determine the relationship between risk factors for the development of chronic non-communicable diseases and first-time preliminary diagnoses during the medical examination of the adult population of Eastern and South - Eastern administrative districts of Moscow. Determine the risk factors that cause the most significant effect for the development of diseases of the endocrine system and eating disorders and metabolic disorders. The analysis of the medical examination data with a comprehensive assessment of the data from industry statistical reports, including the report form N 131, approved by the order of the Ministry of Health of the Russian Federation. It was found out that the risk factors identified during the medical examinations cause the development of chronic non-communicable diseases and the dynamics of indicators for the identified risk factors for obesity and established preliminary diagnoses of obesity from endocrine system diseases, eating disorders and metabolic disorders are equally directed. These percentages of preliminary diagnoses established during the medical examinations can be used for rapid assessment of the quality of the medical examinations and the adoption of cross-sectoral connections and measures aimed at preventing the development of this pathology at the regional level, with a broader implementation of preventive measures to improve public health, including monitoring and measures to reduce the impact of risk factors associated with insufficient physical activity, poor nutrition through the involvement of agencies, responsible for maintaining urban planning and transport policies and requirements for the urban environment, as well as the availability of medical care.

Objectives: The use of psychoactive prescription medication is increasing in the general population. This is a cause for concern, particularly among the elderly, where physiological changes related to senescence increase the risk for adverse effects. While previous studies regarding psychoactive substance use have generally been population based, we sought to determine the frequency of such use among acutely hospitalised patients., Setting: Two emergency departments (EDs), one in Oslo and one in Moscow, admitting patients to Departments of Internal Medicine., Participants: 5583 patients aged ≥18 years participated, distributed evenly between genders and study locations. Patients unable to give informed consent were excluded. The study sites did not admit patients with surgical conditions and/or injuries., Primary and Secondary Outcomes: The presence of psychoactive substances was determined through blood analysis using liquid chromatography-mass spectrometry. Secondary outcomes comprised demographic data (including age, gender, employment and marital status), degree of psychological distress, concurrent alcohol use, and self-reported alcohol, psychoactive drug and illicit substance use., Results: 32.3% in Oslo and 12% in Moscow were positive for one or more psychoactive medicinal drugs (benzodiazepines, z-hypnotics, opioids or barbiturates). In Oslo, medicinal drug use was associated with being aged 61 to 70 years (OR 2.40, 95% CI 1.61 to 3.58) compared with 18 to 40 years, and psychological distress (OR 2.61, 95% CI 2.06 to 3.30). In Moscow, psychoactive medicinal drug use was also associated with psychological distress (OR 1.68, 95% CI 1.18 to 2.39), and was less common among patients aged 41 to 60 years (OR 0.62, 95% CI 0.43 to 0.88) than among patients aged 18 to 40 years., Conclusion: A significant proportion of admitted patients used one or more psychoactive medicinal drugs, in particular benzodiazepines (Oslo and Moscow) and opiates (Oslo). We suggest formalised screening for inappropriate prescription drug use and increased adherence to clinical prescription guidelines., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

The purpose of the study is to analyze patterns demonstrated by the COVID-19 epidemic process in a megacity during the increase, stabilization and reduction in the incidence, and to evaluate the effectiveness of the epidemic prevention measures., Materials and Methods: The comprehensive study incorporating epidemiological, molecular genetic and  statistical research methods was conducted to analyze the spread of SARS-CoV-2 in Moscow during the COVID- 19 pandemic., Results and Discussion: It was found that the exponential growth in COVID-19 cases was prevented due to the most stringent control and restrictive measures deployed in Moscow to break the chains of SARS-CoV-2 transmission and due to people who were very disciplined in complying with the self-isolation rules. The  analysis of the dynamics in detection of new COVID-19 cases showed that in a megacity, the impact of social distancing and self-isolation would become apparent only after 3.5 incubation periods, where the maximum length of the period is 14 days. It was discovered that the detection frequency of SARS-CoV-2 RNA in relatively healthy population and its dynamics are important monitoring parameters, especially during the increase and stabilization in the COVID-19 incidence, and are instrumental in predicting the development of the epidemic situation within a range of 1-2 incubation periods (14-28 days). In Moscow, the case fatality rate was 1.73% over the observation period (6/3/2020-23/6/2020)., Conclusion: The epidemiological analysis of the COVID-19 situation in Moscow showed certain patterns of the SARS-CoV-2 spread and helped evaluate the effectiveness of the epidemic prevention measures aimed at  breaking the routes of transmission of the pathogen.

Objectives : To estimate the incidence of amyotrophic lateral sclerosis (ALS) in Moscow by investigating multiple sources of cases. Incidence rates from previous Russian studies ranged from 0.3 to 0.7 per 100,000/year. Methods : A retrospective study of the incidence of ALS was performed in the South district of Moscow (population, 1,760,000, 2015). Several data sources were investigated. The medical records of the calendar year 2015 were examined by an ALS expert who accepted only patients with definite or probable ALS according to the revised El Escorial criteria. Crude and standardized incidence rates were calculated, the latter adjusted to the Russian and the European population. Results : Twenty-two patients were found, accounting for a crude incidence of 1.25/100,000/year (95% CI 0.78-1.89) and a standardized incidence of 1.22 (Russia) and 1.28 (Europe). The sample included 11 men and 11 women aged 36-73 years (mean 56). Five patients (23%) had bulbar onset ALS. The mean diagnostic delay was 12.8 ± 9.2 months (8.5 ± 4.8 in men and 17.2 ± 10.6 in women) ( p  = 0.02). Family history of ALS was present in two cases. Conclusion : The incidence of ALS in the Russian Federation is higher than previously reported but lower than in other countries. Poor diagnostic ascertainment, particularly in women, and the shorter life expectancy of the Russian population are possible explanations.

Background: Between 1999 and 2008 Russia experienced a flare-up of transmission of vivax malaria following its massive importation with more than 500 autochthonous cases in European Russia, the Moscow region being the most affected. The outbreak waned soon after a decrease in importation in mid-2000s and strengthening the control measures. Compared with other post-eradication epidemics in Europe this one was unprecedented by its extension and duration., Methods: The aim of this study is to identify geographical determinants of transmission. The degree of favourability of climate for vivax malaria was assessed by measuring the sum of effective temperatures and duration of season of effective infectivity using data from 22 weather stations. For geospatial analysis, the locations of each of 405 autochthonous cases detected in Moscow region have been ascertained. A MaxEnt method was used for modelling the territorial differentiation of Moscow region according to the suitability of infection re-emergence based on the statistically valid relationships between the distribution of autochthonous cases and environmental and climatic factors., Results: In 1999-2004, in the beginning of the outbreak, meteorological conditions were extremely favourable for malaria in 1999, 2001 and 2002, especially within the borders of the city of Moscow and its immediate surroundings. The greatest number of cases occurred at the northwestern periphery of the city and in the adjoining rural areas. A significant role was played by rural construction activities attracting migrant labour, vegetation density and landscape division. A cut-off altitude of 200 m was observed, though the factor of altitude did not play a significant role at lower altitudes. Most likely, the urban heat island additionally amplified malaria re-introduction., Conclusion: The malariogenic potential in relation to vivax malaria was high in Moscow region, albeit heterogeneous. It is in Moscow that the most favourable conditions exist for vivax malaria re-introduction in the case of a renewed importation. This recent event of large-scale re-introduction of vivax malaria in a temperate area can serve as a case study for further research.

Dipylidium caninum is a parasite that commonly infects dogs and cats worldwide. The large population of wild and stray dogs and cats may potentially transmit D. caninum to humans via their flea and lice. Humans are an accidental host, and dipylidiasis is more commonly seen in infants and children. There is scant information about human dipylidiasis in Russia. We report nine cases of dipylidiasis - eight in children and one in an adult. The patients were asymptomatic, except for excreting active proglottids in their faeces, which was the most common complaint. The clinical significance of asymptomatic dipylidiasis is not understood, except mothers were anxious because of the continuous appearance of active worms in the faeces of their children. The patients were successfully treated with praziquantel (15 mg/kg). Preventing dipylidiasis in pets and humans requires the control of fleas and lice, avoiding the outdoor defecation of definitive hosts, deworming pets, preventing children from playing with stray animals and spread of information about dipylidiasis among pet owners. Dogs and cats in many places in Russia breed freely, defecate outdoors in any area, and are not subjected to deworming and insect control. These circumstances favour the fact that, although this zoonosis is rare, it is a re-emerging disease and might reach important levels in Russia.

Background: A number of factors can lead to differences in infectious disease morbidity in children versus adults after a trip abroad. We aimed to investigate the epidemiological and etiological features of infectious diseases in children after international travel., Methods: we analyzed the medical records of 2135 patients (416 children) who were hospitalized during the period 2009-2017 after return from international travel., Results: Hospitalized children were under the age of 1 year in 8.7% of cases, 1-3 years - 39.4%, 4-6 years - 17.3%, 7-11 years - 16.8%, 12-17 years - 17.8%. Children were hospitalized after visiting the following main destinations: Turkey (15%), Egypt (12%), Central Asia microregion [11%] and Thailand (9%). Hospitalizations among children occurred mainly in summer (38.0%; CI 33.3-42.4). In adults there were no significant seasonal differences. Children were more likely to have acute diarrhea (18.3 vs 11.1%), acute respiratory tract infections (51.2 vs 41.2%) and enterovirus infections (8.2 vs 3.1%). Among the non-endemic infections for Russia, 8 children were diagnosed with dengue fever, 1 with typhoid, 1 with malaria, and 1 with wild-poliovirus excretion., Conclusion: children were mainly hospitalized during summer. Among hospitalized children, almost half was under 3 years old. In children acute respiratory infection and intestinal infections predominated, while in adults, vector-borne diseases were more frequently observed., (Copyright © 2019 Elsevier Ltd.

The aim of this study was to assess which Mycoplasma pneumoniae genotypes were present in Moscow during the years 2015-2018 and whether the proportion between detected genotypes changed over time. We were also interested in the presence of macrolide resistance (MR)Mycoplasma pneumoniae. We performed multilocus variable-number tandem-repeat (VNTR) analysis (MLVA), SNP typing, and mutation typing in the 23S rRNA gene from 117 M. pneumoniae clinical isolates. Our analysis suggests two major MLVA types: 4572 and 3562. In 2017-2018, MLVA type 4572 gradually became predominant. In general, the SNP type range is the same as described earlier for European countries. The analysis of MR mutations showed that 7% of the isolates had an A2063G mutation in the 23S rRNA gene with no isolates carrying an A2064G mutation. In 2017-2018, MLVA type 4572 (SNP type 1) begins to spread in Moscow, which was widespread globally, especially in Asian countries. SNP typing of our sample showed higher discriminatory power than MLVA typing.

Objectives: To find residential areas with high incidence rate of tuberculosis in Moscow using spatio-temporal analysis of incidence data., Methods: We analyzed the spatial patterns of residence locations of smear or culture positive patients with pulmonary tuberculosis in Moscow. To identify clusters with high local incidence rates, the neighborhoods of detected cases were studied. We assessed the spatial and temporal stability of clusters., Results: For 19033 cases diagnosed with smear or culture positive pulmonary tuberculosis among residents of Moscow in 2000-2015 we identified 18 small-scale clusters of increased incidence rate responsible for 3% of all registered cases identified on a territory inhabited by only 1% of the population. Locations of clusters were sufficiently stable in space throughout the whole period. The local incidence rate inside clusters was significantly (3-4 times) higher than the city average during the whole observation period. The presence of clusters was associated with the incidence rate in the surrounding area. Socio-demographic characteristics of patients in clusters were not significantly different from the average characteristics of patients in the city., Conclusions: The detected small-scale clusters of increased incidence may be used to target active case finding for tuberculosis. The causes and mechanisms of cluster formation and stability need further study., (Copyright © 2019 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Objective: To analyze the influence of surgical sanation of patients with destructive tuberculosis on the prevalence of tuberculosis and mortality., Material and Methods: The strategy of treatment for new cases of destructive pulmonary tuberculosis was developed in the Perelman Department of Phthisiopulmonology and Thoracic Surgery of the Sechenov First Moscow State Medical University. This strategy was applied in the tuberculosis surgical department of the Tambov Regional Dispensary in 2013-2017. A register of patients with pulmonary destruction and bacterial excretion was developed and personal treatment plans were applied. Patients were divided into 3 groups depending on the treatment mode. The main group A consisted of patients who underwent surgical treatment. Surgery was not performed due to failure or discontinuation of treatment in the comparison group B. Group C included patients without indications or with contraindications for surgical treatment., Results: Treatment efficacy considering destruction cavities closure and abacillation was 97.2% in group A, 41.4% in group B and 39.8% in group C. Surgical approach for patients with destructive tuberculosis reduced the number of patients in the register by 3.3 times (from 516 to 158) within 4 years. A significant reduction of the bacillary core allows breaking the infection chain, that affects the main epidemiological indicators. Reduced incidence of tuberculosis is observed in short-term period, but even greater impact of this factor should be expected in long-term follow-up., Conclusion: Surgical approach in complex treatment of destructive pulmonary tuberculosis is valuable to improve efficacy of management of these patients and reduce mortality rate.

The serum of 1006 children aged 0-18 years and elderly people aged 60 to 90 years and older for the presence of specific class G immunoglobulins to the Epstein-Barr virus was studied using enzyme immunoassay. The dependence of seropositivity of children on their age and seropositivity of more than 98% of all surveyed elderly people is shown., Competing Interests: The authors declare no conflict of interest.

The aim of work is to study dynamics of frequency of alcohol intoxications incidence revealed at forensic examination of corpses in Moscow. Frequency of intoxications incidence was determined as index making a share part of cases where ethyl alcohol was found in blood of corpses, comparing to total number of forensic autopsies. For every calendar year of the five-year period from 2014 till 2018 the comparative analysis of frequency of incidence of alcohol intoxications at concrete types of death was carried out. We defined the trend and the rate of changes of alcohol intoxications frequency. During the period from 2014 to 2017 we discovered the strong tendency to reduction of number of alcohol intoxications at violent death. In 2018 the rate of reduction decreased.

Objective: The article presents an analysis of pre-hospital diagnosis of stroke in children., Material and Methods: Pediatric Stroke Center of Morozov Children's City Clinical Hospital (Center) for the period from October 2018 to December 2019, 502 cases of hospitalization of children by the First aid Station to the Center with directing diagnoses of ischemic stroke (IS), haemorrhagic stroke (HS), transient ischemic attack (TIA), vertebrobasilar syndrome (VBS) were analysed., Results and Conclusion: TIA was the most prevalent diagnosis made by the First aid station, with the lowest rate of confirmation after further examination in the hospital (7.8%). The higher rates of confirmation were observed for VBS (31.5%), IS (11.2%) and HI (9.1%). The so-called «masks of stroke» were diagnosed in 84.3% cases of hospitalizations that was in line with earlier studies, which reported 50 to 93%. Based on the data on the frequency of symptoms, their combinations and specificity, a screening scale for pre-hospital diagnosis of stroke in children was suggested.

Vitamin D deficiency is widespread in patients with cystic fibrosis (CF). From 2016 to 2018, prophylactic doses of vitamin D were prescribed for the patients of the Russian cystic fibrosis Center in accordance with the National cystic fibrosis consensus and they were informed about the role of vitamin D deficiency. The aim of the study was to conduct a comparative analysis of the frequency of deficiency and insufficiency of vitamin D in children with CF of different ages in Moscow region in 2016 and 2018. Material and methods . The study involved 115 patients with CF at the age of 0-18 in 2016 and 211 children of the same age in 2018. All children underwent determination of 25(OH)D in blood serum by ELISA. Results and discussion . The frequency of vitamin D deficiency and insufficiency [25(OH)D level <30 ng/ml] in CF patients in 2016 was 64.3%, and in 2018 - 48.7%. Among children of 0-3 years normal serum 25(OH)D levels (>30 ng/ml) were registered in 62.5% in 2016 and in 62.2% in 2018, in children of 4-11 years - 28.8% in 2016 and 58.1% in 2018, among adolescents (11-18 years) - 11.8 and 30.2%, respectively. Conclusion . Comparative analysis showed a positive dynamics in reducing the proportion of CF patients with vitamin D deficiency and insufficiency against the background of continuous use of prophylactic doses of cholecalciferol and educational work for the period from 2016 to 2018. However, in a significant proportion of patients (48.7%), vitamin D level did not reach the norm in 2018 that requires the correction of preventive doses and increase in patient compliance., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)

The article presents the results of analysis of indices of total morbidity of population of the Central Federal Okrug (CFD) of the Russian Federation in 2010-2017. The significant differences in indices of total morbidity between the CFD subjects in certain ICD-10 classes were established. The indices of total morbidity of population during study period (8 years) in the Central Federal District factually didn't altered, while dynamics of indices in other subjects was characterized by multidirectionality. The gap in levels of total morbidity of population in the subjects was significant: from 115,123.6 per 100,000 of population in the Kursk Oblast to 194,404.1 per 100,000 of population in the Orel Oblast. The significant difference in rates of increase/ decrease of indices is noted. Thus, in Moscow decrease rate made up to 10%, while in the Orel Oblast morbidity increased up to 13.1%. Besides, in 2017, the Orel Region took a leadership in rate of increasing of total morbidity in such classes of diseases as infectious and parasitic diseases (39.3%), diseases of blood and blood-forming organs (49.1%), diseases of endocrine system (59,1%), diseases of nervous system (26.8%), diseases of respiratory system (28.2%), diseases of musculoskeletal system (16%), malformations (56%). It is very likely that this trend developed under influence of demographic situation in the subject due to significant increasing of percentage of people older than able-bodied age. The city of Moscow occupies leading position in decreasing of rate of prevalence of diseases and last but one place in level of total morbidity being inferior only to the Kursk Oblast. Thus, in Moscow was noted the most significant decreasing of morbidity in classes of infectious and parasitic diseases (26%) and diseases of digestive system (20.6%). The diseases of blood and blood-forming organs (235.2 per 100,000 population) and mental disorders (2353.5 per 100,000 population) were registered the less. The main contribution into trends of increasing or decreasing of indices is made by persons aged 18 years and older (74.1%).

The statistics of causes of death is the informational basis for identifying public health problems. That is why the accurately accounting for mortality from diabetes mellitus, which is a global medical and social problem for society, is important. The study was carried out to analyze the correctness of coding death causes of diabetes mellitus and the frequency of alleged death., Materials and Methods: The Moscow deceased population database of July 2018 - July 2019 was analyzed. Using the decision tables on codes linkages from ICD-10, incorrect codes for underline cause were established for 342 death cases from diabetes mellitus. Among 43044 cases of cardiovascular death the cases of presumed death from diabetes were detected. The analysis was carried out in the Microsoft Access 2007 software., The Results: In 18.4% of cases, the cause of death from diabetes was encoded incorrectly. If a modification of the underline death cause is assumed due to the mention of certain diseases in any line of the Death Certificate, cases of coding for death from diabetes with wrong fourth character are more often detected when mentioning kidney diseases. If modification of the underline cause is provided for cases when information in the Death Certificate indicates that diabetes has caused the development of some diseases then the largest number of cases with incorrect coding was detected when mentioning circulatory diseases. Only in one medical organization the frequency of incorrect coding is 3.4%, in the rest it varies from 15.4% to 52.2%. Among all death causes, diabetes was only 0.41%. If to add cases of presumptive death from diabetes mellitus, then the proportion of diabetes in the structure of death causes will almost triple and reach up to 1.2%., Conclusions: The quality of diagnosis and coding of death causes from diabetes has not improved in recent years. To increase it, it is advisable to organize and establish the institution of coders. It is advisable to indicate the presence of diabetes mellitus in the Death Certificate without fail and use the information from the diabetes register. It is proposed to encode the death cause from diabetes mellitus with multiple complications use line D in the Death Certificate to indicate damage to various organs and systems if it is necessary.
