Published: March 2021

The parameters of several populations of immune cells (T cell populations, macrophage subpopulations) in peripheral blood and brain were studied in a clinically significant model of mild traumatic brain injury among rats. The population of resident cells of innate immunity of microglia and brain astrocytes with local tissue damage is involved in the implementation of the inflammatory response, it is also shown that in case of trauma, blood leukocytes can overcome the blood-brain barrier and penetrate the brain parenchyma. The methods of flow cytometry and immunofluorescence were used. An increase in the number of monocytes and neutrophils up to 1 day, after a mild traumatic brain injury (TBI) with a subsequent decrease to the end of the observation period was noticed. It was determined, that the number of CD45+ cells, CD3+T cells decreased at 1 days post-injury (dpi), and rose slightly by 14 dpi, the percentage of CD4+T cells continuously declined from 7 to 14 dpi, while the percentage of CD8+T cells increased from 7 to 14 dpi. With mild traumatic brain injury in animals, a significant (3-10 times) decrease in the number of microvessels with a positive reaction to the presence of SMI 71 on the 8th and 14th day after head injury was observed. Intensive staining of SMI 71 microvessels was sometimes observed with an increase in the area of a positive reaction. Thin positive deposits of the reaction product are observed in the brain of healthy animals around the wall of the microvessel. In the damaged brain, CD45high/CD11b+ positive macrophages of the M1 subpopulation appeared in the brain tissue on the 2nd day after TBI and a significant amount was observed on the 8-14th day. In the corpus callosum and ipsilateral region of the striatum, the content of cells expressing CD16/11b+ reached a maximum 8 days after TBI, which correlated with a decrease in the positive response to the presence of endothelial antigen SMI 71. Thus, in the acute period of mild TBI, the presence of neuroimmunopathological processes is determined in the brain, which can subsequently result to the dysregulation of neuroimmune connections.

Despite the success in prevention and therapy, influenza remains a mass disease with mortality rate up to 0.01—0.2% worldwide.Purpose. Conducting clinical and laboratory analysis of influenza infection cases and evaluating their etiological significance in adult hospitalized patients during 2018—2019 epidemic season. Materials and methods. There were analyzed 569 case histories of patients hospitalized at the Clinical Infectious Diseases Hospital named after S.P. Botkin. Patients were examined by PCR that resulted in verified influenza virus in 260 cases. Nasopharyngeal swabs collected from 36 patients were examined by virological method on MDCK cell culture. 24 influenza virus strains were isolated and identified.Results. The study allowed to identify a viral landscape represented by influenza viruses A and B found in 98.5% and 1.5% cases, respectively. Influenza viruses isolated on cell culture in 50% of cases were identified. Among the influenza viruses isolated on cell culture there were identified serotype A influenza viruses (H1N1) closely related to the pandemic influenza A (H1N1)pdm09. Some isolates (41.7%) belonged to serotype A (H3N2), which were related to strain A/Singapore/16-0019/16. Influenza B virus strain of the Victoria lineage isolated from a hospitalized patient possessed a triple deletion in hemagglutinin gene, which antigenic properties substantially differed from those of the influenza virus strain being included into current influenza vaccines. Upon admission, the condition of most patients was estimated as moderate (males — 48.7%, females — 51.3%). The median patient age was 35 years old, with comorbidities being registered in 50% cases. The clinical picture for 2018—2019 seasonal influenza displayed no distinctive features as compared to previous epidemic seasons. The duration of intoxication and catarrhal syndrome was 4.3±0.13 and 6.9±0.29 days, respectively, with median body temperature ranging within 39.2±0.06°С. All patients received standard pathogenetic therapy. Complications were noted in 86.7% cases such as pneumonia — 11.1%, sinusitis — 6.9%, bronchitis — 56.9%. The bed day length was 5.93±0.29, no lethal outcomes were recorded.Conclusion. It was found that influenza A viruses were dominant in patients observed comprising up to 98.5% cases, whereas influenza viruses B were found in as few as 1.5% patients. The clinical picture was characterized by severe intoxication and catarrhal syndrome, being frequently associated with complications.

Due to the ubiquitous spread of SARS-CoV-2 coronavirus infection, the demand for anaesthesia and respiratory devices has significantly increased since the beginning of 2020. In particular, artificial ventilation devices, inhalation anaesthesia devices, or oxygen inhalers. The respiratory support devices must include special medical devices designed to heat and increase the moisture content of the respiratory mixture supplied to the patient from the respiratory therapy apparatus. These medical devices are known to as humidifiers. The production of a humidifier for breathing mixtures “TEVLAR” – “UOMZ” according to TU 32.50.21-121-07539541-2018 with accessories was organized jn the territory of Joint Stock Company “Production Association “Urals Optical & Mechanical Plant” named after Mr. E. S. Yalamov”. The electronic measuring instruments unit of the device has been modified within the framework of the project for the modernization of the humidifier of breathing mixtures “TEVLAR” – “UOMZ”. In particular, in order to increase the accuracy of thermal stability of the heating element when heating the breathing mixtures to the target temperature, the software of the electronic measuring instruments unit was modernized by the Medical Devices Design Bureau, namely, the stable PID controller was implemented and tuned. Thus, this article provides an overview of the methods for tuning the PID controller, justifies the choice of PID tuning by the Ziegler-Nichols method and also provides the experimental results to confirm device operation stability.
Redistribution and the Monetary–Fiscal Policy Mix
Authors: Bhattarai Saroj , Lee Jae Won , Yang Choongryul
Published: March 2021

We show that the effectiveness of redistribution policy in stimulating the economy and improving welfare is directly tied to how much inflation it generates, which in turn hinges on monetary-fiscal adjustments that ultimately finance the transfers. We compare two distinct types of monetary-fiscal adjustments: In the monetary regime, the government eventually raises taxes to finance transfers, while in the fiscal regime, inflation rises, effectively imposing inflation taxes on public debt holders. We show analytically in a simple model how the fiscal regime generates larger and more persistent inflation than the monetary regime. In a quantitative application, we use a two-sector, two-agent New Keynesian model, situate the model economy in a COVID-19 recession, and quantify the effects of the transfer components of the Coronavirus Aid, Relief, and Economic Security (CARES) Act. We find that the transfer multipliers are significantly larger under the fiscal regime—which results in a milder contraction—than under the monetary regime, primarily because inflationary pressures of this regime counteract the deflationary forces during the recession. Moreover, redistribution produces a Pareto improvement under the fiscal regime.

The article analyzes the findings on the Neolithic burial discovered at the Udachny-14 burial site in the city of Krasnoyarsk. The skeleton of a child of 9–10 years old was located head to the south-west parallel to the river (upstream). Over the grave there is a hearth in which the red deer calcaneal bone is found. Between the skull and the pelvis bones, two beaver incisors lying parallel to each other, could relate to clothing or to decoration. A piece of ochre was found near the left instep bones. Almost all the bones of the legs of the buried individual were in anatomical order and were elongated along the long burial axis. The corpus bones, shoulder girdle and head were greatly displaced. Such order of the bones suggests that the grave was disturbed a short time after the funeral. Odontologic examination of the remains shows a combination in the dentition structure of the “eastern” and “western” signs with a predominance of the first ones. The greatest odontologic similarity of the buried individual is related to a few Neolithic series from the Northern Angara region, which partially correlates with the archaeological data. Based on the 14C date and the stratigraphic position, the burial is dated to the late Neolithic (the end of the 4th millennium BC). Among the few sites in the region, it finds analogies in the necropolises of “Bor” urotshistshe at the mouth of the Bazaikha river, near the summer children’s camps of the GorONO and in the Gremyachiy Ruchei burial ground. They are characterized by the soil burials, the grave pits located mainly along the river, postmortal manipulations with the dead body, over- or near grave fire, use of jewellery made of teeth and animal bones as accompanying burial objects

Published: March 2021

BACKGROUND: Currently, brucellosis continues to pose a serious problem for public health and agriculture in Russia. In 2019, the number of Russian cases of bovine brucellosis increased by 14%, and the number of first-time identified poor points for small cattle brucellosis increased by 52%. Epizootics of the disease are registered mainly in North Caucasus and Southern Federal districts, and the maximum number of newly detected brucellosis in humans is recorded in the Republic of Dagestan (RD).
AIMS: This study aimed to present the characteristics of brucellosis incidence in the RD in 2019 and optimization of preventive measures.
MATERIALS AND METHODS: The study used state information on the incidence of brucellosis, mechanisms, ways, factors of pathogen transmission, and epidemic control activities of the infection in 2019 in the RD, provided by the S.M. Magomedov Republican Center of Infectious Diseases, Prevention and Fight Against AIDS and the Office of the Federal Service for Veterinary and Phytosanitary Surveillance of the RD. Statistical and epidemiological research methods were applied.
RESULTS: In 2019, 163 new cases of brucellosis were registered in the RD, which was 52 (+47%) cases more than those in the same period in 2018, and the number of new cases of chronic brucellosis significantly increased (p 0.05). Individuals aged 41 years were more likely to get sick, patients were predominantly men (n = 135, 82.8%), rural residents accounted for 84.2%, and 56.1% were owners of personal livestock. Brucellosis was registered in 40 territories of the RD. The incidence rate was six times higher in rural areas than in urban areas. In humans, the source of infection was sheep and goats in 58.8% and cattle in 41.2% of cases. The main factor in the persistently high incidence of brucellosis in the RD was unsatisfactory examination and specific prevention among cattle, goats, and sheep.
CONCLUSIONS: Thus, the epizootological and epidemiological situation of brucellosis in the RD should be considered unstable at present. With respect to the future of the brucellosis situation in the RD, the incidence of brucellosis in animals and humans will depend on the completeness of the implementation of plans for disease prevention.

Published: March 2021

Most of the studies on models with retrials are devoted to the research of the number of applications in the system or in the source of repeated calls using asymptotic and numerical approaches or simulation. Although one of the main characteristics that determines the quality of the communication system is the number of applications served by the system per unit of time. Information on the characteristics of the output processes is of great practical interest, since the output process of one system may be incoming to another. The results of the study of the outgoing flows of queuing networks are widely used in the modeling of computer systems, in the design of data transmission networks and in the analysis of complex multi-stage production processes. In this paper, we have considered a single server system with redial, the input of which receives a stationary Poisson process. The service time in considered system is a random value with an arbitrary distribution function B(x). If the customer enters the system and finds the server busy, it instantly joins the orbit and carries out a random delay there during an exponentially distributed time. The object of study is the output process of this system. The output is characterized by the probability distribution of the number of customers that have completed service for time t. We have provided the study using asymptotic analysis method under low rate of retrials limit condition. We have shown in the paper that the output of retrial queue M|GI|1 is an asymptotical renewal process. Moreover, the lengths of the intervals in output process are the sum of an exponential random value with the parameter lambda + kappa and a random variable with the distribution function B(x). The results of a numerical experiment show that the probability distributions of the number of served customers in the system are practically the same for significantly different distribution laws B(x) of service time if the service times have the same first two moments.

In this paper, we consider a single server retrial queue MMPP|M|1 with two way communication and multiple types of outgoing calls. Calls received by the system occupy the device for operating, if it is free, or are sent to orbit, where they make a random delay before the next attempt to occupy the device. The duration of the delay has an exponential distribution. The main issue of this model is an existence of various types of outgoing calls in the system. The intensity of outgoing calls is different for different types of outgoing calls. The operating time of the outgoing calls also differs depending on the type and is exponential random variable, the parameters of which in the general case do not coincide. The device generates calls from the outside only when it does not operate the calls received from the flow. We use asymptotic analysis methods under two limit conditions: high rate of outgoing calls and low rate of serving outgoing calls. The aim of the current research is to derive an asymptotic stationary probability distribution of the number of incoming calls in the system that arrived from the flow, without taking into account the outgoing call if it is operated on the device. In this paper, we obtain asymptotic characteristic function under aforementioned limit conditions. In the limiting condition of high intensity of outgoing calls, the asymptotic characteristic function of the number of incoming calls in a system with repeated calls and multiple types of outgoing calls is a characteristic function of a Gaussian random variable. The type of the asymptotic characteristic function of the number of incoming calls in the system under study in the limiting condition of long-term operation of the outgoing calls is uniquely determined.

In this paper, a mathematical model of complex oscillations of a flexible micropolar cylindrical mesh structure is constructed. Equations are written in displacements. Geometric nonlinearity is taken into account according to the Theodore von Karman model. A non-classical continual model of a panel based on a Cosserat medium with constrained particle rotation (pseudocontinuum) is considered. It is assumed that the fields of displacements and rotations are not independent. An additional independent material parameter of length associated with a symmetric tensor by a rotation gradient is introduced into consideration. The equations of motion of a panel element, the boundary and initial conditions are obtained from the Ostrogradsky – Hamilton variational principle based on the Kirchhoff – Love’s kinematic hypotheses. It is assumed that the cylindrical panel consists of n families of edges of the same material, each of which is characterized by an inclination angle relative to the positive direction of the axis directed along the length of the panel and the distance between adjacent edges. The material is isotropic, elastic and obeys Hooke’s law. To homogenize the rib system over the panel surface, the G. I. Pshenichnov continuous model is used. The dissipative mechanical system is considered. The differential problem in partial derivatives is reduced to an ordinary differential problem with respect to spatial coordinates by the Bubnov – Galerkin method in higher approximations. The Cauchy problem is solved by the Runge – Kutta method of the 4th order of accuracy. Using the establishment method, a study of grid geometry influence and taking account of micropolar theory on the behavior of a grid plate consisting of two families of mutually perpendicular edges was conducted.
Repeated alternating loading of a elastoplastic three-layer plate in a temperature field

Published: March 2021

Axisymmetric deformation of a three-layer circular plate under repeated alternating loading from the plastic region by a local load is considered. To describe kinematics of asymmetrical on the thickness of the plate pack is adopted the hypothesis of a broken line. In a thin elastic-plastic load-bearing layers are used the hypothesis of Kirchhoff. A non-linearly elastic relatively thick filler is incompressible in thickness. It is taken to be a hypothesis of Tymoshenko regarding the straightness and the incompressibility of the deformed normals with linear approximation of the displacements through the thickness layer. The work of the filler in the tangential direction is taken into account. The physical relations of stress-strain relations correspond to the theory of small elastic-plastic deformations. The effect of heat flow is taken into account. The temperature field in the plate was calculated by the formula obtained by averaging the thermophysical parameters over the thickness of the package. The system of differential equations of equilibrium under loading of the plate from the natural state is obtained by the Lagrange variational method. Boundary conditions on the plate contour are formulated. The solution of the corresponding boundary value problem is reduced to finding the three desired functions: deflection, shear and radial displacement of the shear surface of the filler. A non-uniform system of ordinary nonlinear differential equations is written for these functions. Its analytical iterative solution is obtained in Bessel functions by the method of elastic solutions of Ilyushin. In case of repeated alternating loading of the plate, the solution of the boundary value problem is constructed using the theory of variable loading of Moskvitin. In this case, the hypothesis of similarity of plasticity functions at each loading step is used. Their analytical form is taken independent of the point of unloading. However, the material constants included in the approximation formulas will be different. The cyclic hardening of the material of the bearing layers is taken into account. The parametric analysis of the obtained solutions under different boundary conditions in the case of a local load distributed in a circle is carried out. The influence of temperature and nonlinearity of layer materials on the displacements in the plate is numerically investigated.

Introduction: Being infected with COVID-19 is associated with direct and indirect effects on the cardiopulmonary system and electrocardiography can aid in management of patients through rapid and early identification of these adversities.
Objective: The present study was designed aiming to evaluate electrocardiographic changes and their correlation with the outcome of COVID-19 patients.
Methods: This Prospective cohort study was carried out on COVID-19 cases admitted to the emergency department of an educational hospital, during late February and March 2020. Electrocardiographic characteristics of patients and their association with in-hospital mortality were investigated.
Results: One hundred and nineteen cases with the mean age of 60.52±13.45 (range: 29-89) years were studied (65.5% male). Dysrhythmia was detected in 22 (18.4%) cases. T-wave inversion (28.6%), pulmonale P-wave (19.3%), left axis deviation (19.3%), and ST-segment depression (16.8%) were among the most frequently detected electrocardiographic abnormalities, respectively. Twelve (10.1%) cases died. There was a significant correlation between in-hospital mortality and history of diabetes mellitus (p=0.007), quick SOFA score > 2 (p<0.0001), premature ventricular contraction (PVC) (p=0.003), left axis deviation (LAD) (p=0.039), pulmonale P-wave (p<0.001), biphasic P-wave (p<0.001), inverted T-wave (p=0.002), ST-depression (p=0.027), and atrioventricular (AV) node block (p=0.002). Multivariate cox regression showed that history of diabetes mellitus, and presence of PVC and pulmonale P-wave were independent prognostic factors of mortality.
Conclusions: Based on the findings of the present study, 18.4% of COVID-19 patients had presented with some kind of dysrhythmia and in addition to history of diabetes, presence of PVC and pulmonale P-wave were among the independent prognostic factors of mortality in COVID-19 patients.

Published: March 2021

Introduction: Limb swelling is among the frequent complaints of patients referring to the emergency room (ER).
Objective: We decided to take a step towards facilitating the diagnostic process of patients who refer to ER with such complaint, and find out whether emergency medicine physicians (EMPs) can play an effective role in this regard.
Methods: This was a diagnostic accuracy study in which all patients who referred to the ER with a complaint of unilateral leg swelling were studied. The patients underwent bedside sonography by the researchers, who were emergency medicine physicians (EMPs), and also underwent a second sonography by the in-charge radiologist using the same device and probe. The accuracy of the diagnoses made by researchers was evaluated using the radiologists’ opinion as the gold standard.
Results: In this study, the data of 52 patients were analyzed. In general, the agreement rate between the EMPs and radiologists was 0.863, which indicates a proper agreement. Based on the findings, Kappa agreement for the four differential diagnoses ranged from 0.639 to 0.919 and the AUC was between 0.750 and 0.976.
Conclusions: In this study, the overall agreement between the EMPs and radiologists was appropriate.

Published: March 2021

Background: Dislocation of total hip arthroplasty (THA) needs prompt intervention and reduction either closed or open. It is unusual to left THA dislocated. Hence in this study, the outcomes of neglected prosthesis after THA were determined.
Methods: In this case series study, 15 neglected cases of total hips which had been left unreduced for long time (more than 3 months) were assessed. Cause of postponing reduction, femoral side and acetabular side defects, approach and type of revised prosthesis, Harris hip score (HHS), and other complications were studied.
Results: The results in this study demonstrated that financial issues were the cause of delayed attempt for treatment in 5 cases and the other 10 cases had delay for treatment, because they searched for a specialist to accept performing an operating on them. There were some acetabular side and femoral side defects. By Paprosky classification, in femoral side, there were 6 defects: four type 2, one type 3A, and one 3B. In acetabular side, there were 10 defects (three type 1, one type 2a, three type 2b, one type 3a, and two type 3b). In one developmental dysplasia of the hip (DDH) case, previous osteotomy site was revised (distal segment rotated and then refixed)
Conclusion: Totally, according to the obtained results, it may be concluded that outcomes were relatively good in neglected prosthesis cases after THA. However, recognition of high-risk cases and reduction of delay time may improve the outcomes.

The modern world is experiencing unprecedented pressure from the COVID-19 coronavirus pandemic on the economy and social systems of most countries of the world. Despite the fact that on the eve of the pandemic of humanity on the level of interstate relations and supranational entities was adapted to the global space with the metabolic processes in the fields of culture, production, Finance, technology and service, sudden and prolonged the suspension of domestic, cross border and transcontinental movement of goods and movement of people has led to a sharp disparity in the structure of most national economies and highlighted the vulnerabilities of the current model of civilization. Tourism, which became the engine of economic development in many countries and territories in the twenty-first century, practically became a symbol of economic shipwreck during the pandemic, since, as a multiplier for the industries and areas of activity associated with it, it started a chain reaction of bankruptcies, curtailment of large, medium and small businesses, and stopping air services on domestic and international routes. The social function of tourism, which, as it turned out, to a certain extent was able to mitigate social contradictions in society, offering quite democratic conditions for travel due to the high competition in the field of hospitality in the domestic and international markets, was also more pronounced in the crisis conditions. It is obvious that the restart of tourism in the shortest possible time after the lifting of restrictions will be perceived by the population as the most obvious evidence of the restoration of socio-economic stability of society.

After the advent of the Internet, travel planning has become not only relevant, but also a visual process. Potential tourists book hotels, studying their interior in advance; familiarize themselves with places of recreation and infrastructure of the receiving destination, without leaving the house.; comparing prices; study the feedback of visitors. The modern tourism business is forced to increasingly use information and communication tools in competition for the client. In the scientific literature, the concepts of “virtual tourism” and “virtual tour” are increasingly appearing, and the authors of the articles justify their advantages. Based on a study of publications, it was revealed that Russian economists consider virtual tourism as a new type of tourism, foreign authors use the concepts of “virtual tour” and “virtual reality” more. The development of information technologies takes tourism and recreation organizations to a new level of development. The purpose of the article is to determine the essence of virtual tourism: this is a new type of tourism, innovations in tourism in the context of digitalization or another worldview. This study, conducted by us, will allow us to revise the approach to the traditional definition of “tourism,” which is legally entrenched in Russian practice.
