Published: July 2021

Предлагаются алгоритм и построенная на его основе программа оценки эффективного кодирования источника сигналов при их преобразованиях в различных метрических пространствах (в частности, для широко используемого в настоящее время аналого-цифрового преобразования непрерывного сигнала в двоичный). Алгоритм оценки учитывает показатели искажений при кодировании двоичным кодом,вероятности появления этих искажений при передаче элементов сообщения и вероятности появления сообщения в канале связи. Помимо самого алгоритма, предложены его программная реализация, созданная с помощью языка программирования 0#,а также усовершенствованный интерфейс на базе MS Excel. В программной реализации имеется графическая среда для пользователя.

This paper proposes an algorithm and a program built on its basis for evaluating the effective coding of a signal source during their transformations in various metric spaces, and, in particular, for the currently widely used analog-to-digital conversion of a continuous signal to a binary signal. The estimation algorithm takes into account the indicators of distortions under binary coding, the probability of occurrence of these distortions when transmitting message elements, and the probability of a message appearing in the communication channel. In addition to the algorithm itself, its software implementation, created using the C# programming language, and an improved interface based on MS Excel are proposed. Software implementation has a graphical user environment.

Afroepistemologías, feminismos negros y afrodescendientes en Latinoamérica y el Caribe:
Authors: Corpas Figueroa Jessica Nathalie
Published: July 2021

Este trabajo da cuenta de lo imperativo que resulta en la actualidad articular epistemes para pensar y analizar los problemas sociales desde las ciencias humanas y sociales, en concreto proponemos valorizar el pensamiento afrodescendiente o afroepistemologías, y los feminismos negros y afrodescendientes. Aquí se sugiere un recorte conceptual que articula dichas epistemes, de cara a vislumbrar los puentes que las conectan desde la producción de estos pensamientos en Latinoamérica y el Caribe, profundizando en las contribuciones de Colombia.

Se prioriza el trabajo intelectual de investigadoras/es afrodescendientes, pues se afirma que existen condiciones estructurales que limitan una mayor circulación/apropiación de estos pensamientos en las ciencias sociales, lo cual constituye injusticia epistémica. Aquí se plasman además mis inquietudes e intereses, como investigadora afrodescendiente en el relevamiento de un fenómeno social que sigue siendo periférico dentro del ámbito académico.
Brexit:
Authors: Kirjner Baricco Tomás
Published: July 2021

Este artículo analiza la reciente alza del nacionalismo británico que se dio en el Reino Unido de la mano de cuatro partidos políticos clave (Britain First, UKIP, Brexit Party y Conservative Party), los cuales impulsaron una demanda euroescéptica que desembocó finalmente en el Brexit. Para esto, el trabajo se divide en dos partes: primero, se resumen los dos argumentos euroescépticos principales: la necesidad de reducir la inmigración poco calificada y la exigencia de una mayor soberanía económica; luego, se describe el rol y desempeño electoral de cada uno de los cuatro partidos mencionados previamente. En la segunda parte, entendiendo que el resultado del referéndum terminó evidenciando y profundizando clivajesnacionalistas al interior del Reino Unido, particularmente en Escocia e Irlanda del Norte, donde el grueso de la ciudadanía votó a favor de permanecer en la Unión Europea, se realiza un repaso histórico de los nacionalismos escocés e irlandés, exhibiendo la incidencia que tuvo el Brexit y la pandemia en éstos. Se concluye que el malestar generado por el Brexit pone potencialmente en juego la futura integridad del Reino Unido.
Micronutrientes, inmunidad y COVID-19: una revisión narrativa
Authors: Restrepo Javier
Published: July 2021

Las opciones terapéuticas en el manejo de coronavirus disease 2019 (COVID-19) son limitadas y el proceso de vacunación para proteger contra el contagio del coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2) está iniciando en el mundo. A todo esto, hay que añadir la existencia de un grupo de personas que presentan mayor vulnerabilidad frente a la enfermedad, como son los adultos mayores y las personas con enfermedades crónicas como la obesidad, la diabetes y la hipertensión arterial. Además, los trastornos en el estado nutricional pueden influir en el curso de la enfermedad. Las vitaminas y los oligoelementos desempeñan un papel crucial en la inmunomodulación, por lo que se han postulado como una opción terapéutica. El objetivo de este artículo es mostrar el papel de los micronutrientes en la inmunidad y, en particular, la evidencia actual sobre los efectos de su suplementación en la prevención y el tratamiento de la infección por SARS-CoV-2. La revisión de la literatura muestra que en la actualidad no existen estudios suficientes sobre los beneficios de la suplementación de micronutrientes en el curso de la COVID-19. Una dieta equilibrada y variada es esencial no solo para minimizar las deficiencias de vitaminas, sino también para evitar un consumo excesivo o suplementación innecesaria. Se requieren de estudios aleatorizados controlado que estudien los efectos de la suplementación con micronutrientes en la función inmunitaria y en los resultados clínicos en diferentes poblaciones. Palabras clave: inmunidad, vitaminas, minerales, obesidad, infecciones por coronavirus, SARS-CoV-2.
Etiquetado nutricional frontal y su impacto en la salud pública. Consideraciones bioéticas
Authors: Sierra Tobón Lina María
Published: July 2021

Introducción: en los últimos años, el etiquetado nutricional frontal se ha recomendado como política de protección del derecho a la salud, con el argumento de que permite orientar al consumidor en la elección de alimentos saludables, incentivar a la industria en la reformulación de productos sanos y facilitar el diseño de políticas públicas de alimentación saludable, siendo uno de los principales motivos de su implementación el aumento en la prevalencia de enfermedades no transmisibles relacionadas con la dieta. Objetivo: revisar el impacto del etiquetado nutricional frontal en la salud pública y proponer algunas consideraciones bioéticas que favorezcan su efectividad. Métodos: se realizó una búsqueda bibliográfica, revisando el impacto de dicha medida sobre la salud pública, seguido de una reflexión bioética en torno al tema. Resultados: si bien es cierto, el etiquetado frontal puede incidir en la elección de alimentos, la decisión sobre la compra y el consumo está influenciada por aspectos propios del individuo y su contexto. Se propone considerar el empoderamiento del consumidor, la corresponsabilidad de la industria alimentaria y la protección del estado como fundamentos bioéticos que, acompañados de la discusión en torno a la esencia de la libertad humana y el condicionamiento de los determinantes sociales de salud, favorecerían su efectividad. Conclusiones: la reflexión bioética en torno a la triada consumidor/industria/ estado permite fundamentar una buena praxis en la implementación del etiquetado nutricional frontal de alimentos como política de salud pública. Palabras clave: etiquetado de alimentos, salud pública, bioética.

Authors: Ulloa Jorge H. , Cifuentes Sebastián , Figueroa Valentín , Van Uden Emelyn , Tafur Susana
Published: July 2021

Introducción: el selenio ha demostrado poseer efectos benéficos sobre la salud humana, entre los que destacan el fortalecimiento del sistema inmune, efectos antiinflamatorios y disminución de la lipoxidación. Además, su deficiencia puede ocasionar enfermedades como la enfermedad de Keshan y de Kashin-Beck, ambas con una mortalidad del 50 %, aproximadamente. El objetivo de este artículo es identificar y sintetizar las funciones y ventajas del consumo de huevo enriquecido con selenio en la salud humana. Métodos: se realizó una revisión bibliográfica tanto en español como en inglés en las bases de datos de Google Scholar y Pubmed. Se emplearon los términos “huevo”, “selenio” y “síndrome metabólico”, y se tomaron en consideración aquellos artículos con textos completos disponibles y con relevancia en cuanto a la relación entre el huevo y el selenio. Resultados: se ha evidenciado que el selenio es esencial en nuestra dieta y presenta numerosos efectos benéficos sobre la salud. Actualmente, las tendencias nutricionales van dirigidas no solo a cubrir las necesidades básicas de selenio, sino también a la prevención y tratamiento de enfermedades en humanos. El huevo es un alimento de fácil acceso, bajo costo y de gran aporte nutricional con baja carga calórica, por lo que su enriquecimiento con selenio podría garantizar una adecuada suplencia en la mayoría de la población colombiana. Conclusión: el enriquecimiento del huevo de gallina con selenio no solo ayudaría a prevenir enfermedades, sino que también representaría una medida de prevención de enfermedades y promoción de la salud. Palabras clave: huevo, selenio, salud, síndrome metabólico.

Introducción: en diciembre de 2019 surgieron casos de neumonía de etiología desconocida, que más tarde fueron clasificados como coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2). El 11 de marzo se declaró la pandemia por la enfermedad respiratoria coronavirus disease 2019 (COVID-19), por lo que se recurrió a medidas de contención de la transmisión, como el distanciamiento social y confinamiento, medidas con conocidos efectos estresores que pueden influir en la conducta alimentaria. Por ello, el objetivo de esta investigación es identificar la conducta alimentaria a través de la restricción dietética, alimentación emocional e ingesta incontrolada, y explorar los factores asociados con estas conductas en adultos durante el confinamiento por COVID-19 en países hispanohablantes. Método: se realizará un estudio transversal descriptivo, mediante un cuestionario en línea autoaplicado, el cual estará integrado por un cuestionario de conducta alimentaria (Three-Factor Eating Questionnaire-R18), información sociodemográfica y de salud, y características del estilo de vida antes y durante el confinamiento. Se realizará un análisis descriptivo de las variables, análisis bivariante y modelos de regresión lineal multivariantes para explorar los factores asociados con la conducta alimentaria en el distanciamiento social. Discusión: el confinamiento ha modificado la ingesta de alimentos hacia un patrón alimentario no saludable, reducción de la actividad física e incremento del sedentarismo. Sin embargo, no se ha analizado el papel de esta medida de contención en la conducta alimentaria desde la perspectiva de restricción, emociones e ingesta descontrolada, situación que brinda la oportunidad de estudiar este fenómeno en la población hispana e identificar los posibles factores asociados que puedan sentar las bases de intervenciones durante el confinamiento o posterior a este.

Vitamina D, sus posibles efectos en la función inmune y la respuesta ante la COVID-19: una revisión sistemática exploratoria
Authors: Niño Daniel Armando , Mora-Plazas Mercedes , Poveda Elpidia
Published: July 2021

La enfermedad causada por el coronavirus descubierto más recientemente (COVID-19), induce una respuesta inmune innata rápida y bien coordinada, considerada como la primera línea de defensa contra la infección viral. El objetivo de esta revisión es presentar el estado de la literatura en relación con la vitamina D, el sistema inmune y la COVID-19 sobre artículos publicados en los últimos 10 años hasta el mes de septiembre del 2020. Varias hipótesis describen los mecanismos en los que la vitamina D reduce el riesgo de infecciones ocasionadas por distintos microorganismos. También se ha descrito que la deficiencia de este micronutriente altera negativamente la respuesta inmune ante patógenos. El estado de la literatura científica publicada hasta el mes de septiembre del 2020, respecto a la vitamina D y función inmune en la infección por SARS-CoV-2, ratifica la importancia de mantener los niveles apropiados de vitamina D antes, durante y después de la COVID-19. Adecuados niveles de este micronutriente antes de esta enfermedad infecciosa se asocian con menores tasas de contagio; durante la enfermedad predicen mejores resultados en todos los grupos etarios; y después de la enfermedad podrían asociarse con menores tasas de reinfección de virus latentes. Es necesario que, de manera prioritaria, se promuevan recomendaciones básicas para mantener concentraciones normales de vitamina D, las cuales deberán ir enfocadas mínimamente a los siguientes 3 ítems: aumentar la exposición a la luz solar, consumir alimentos fuente de vitamina D y realizar actividad física. Palabras clave: vitamina D, COVID-19, infección, inmunología, suplementación dietética.

CONCEPTUAL ASPECTS AND THE MOST USED PRACTICES IN OBTAINING THE RELIABILITY OF ENTITY VALUE ESTIMATION
Authors: BIRCA Iulita , Rodica TIRLEA Mariana , GANEA Victoria , BUZU Olga
Published: July 2021

Estimating the entity value is topical and of particular interest to managers and business owners, who in turn hope that through the evaluation they will obtain parallel and new possibilities for the business remediation. In this context, managers seek the support of qualified assessors, who will conduct a thorough analysis of the entity’s state at a given date, will apply the most effective evaluation methods. In this paper we proposed to investigate and analyze the theoretical aspects of the entity value estimation (EVE), rendered in the opinion of the well-informed researchers and in the light of the evaluation standards. As a result, we note that the criteria of evaluations have been supplemented with the following criterion: by type of activity of the economic entity. We estimate the evaluation methods in order to identify the most accepted and effective method for this important process to the entity. For the practical aspect of the investigation, we focused on the method of comparison in the market valuation of the enterprise, in order to establish the statistical indicators consisting of the calculation of the median and the arithmetic mean. Based on the calculations made in the practical part, we have found that an economic entity can change its own value, in particular, by the way its values are profitable. In estimating the value of the entity, a decision-making function is attributed to the rests with the assessor, in particular with regard to the methods selected and applied professionally by the entity, in compliance with professional valuation standards and current regulations, as the fair estimation of the entity’s value leads to a secure future and a guaranteed success.
DEVELOPMENT OF REGIONAL LABOUR MARKETS IN CONDITIONS OF DECENTRALIZATION
Authors: Lidiia TKACHENKO
Published: July 2021

The decentralization reform in Ukraine began in 2014 and is aimed at implementing the provisions of the European Charter of Local Self-Government, which provides for the redistribution of powers, resources and responsibilities on the basis of subsidiarity. Currently, local governments are endowed with powers and instruments of influence on enterprises located on their territory, but employment and labour market policies remains the prerogative of the central government. For a comparative analysis of the development of regional labour markets in the context of decentralization, labour force survey indicators are more appropriate, since they reflect the actual policy results from the perspective of households. For the 2015–2019 period in most regions of Ukraine, there was an increase in the level of employment and a decrease in the level of unemployment; at the same time, the gender gap in employment has increased in 16 of 25 regions; the sectoral structure of employment continues to stagnate. Some regions have significantly increased the coverage of public works, but this may indicate not the activity of territorial communities, but the lack of stable employment opportunities. Local self-government bodies should play a key role in the formation and implementation of local employment and the labour market policies, their interaction with the state employment service requiring a corresponding transformation.

SPF ICE: A Novel Approach to Model the Amount And Effectiveness of Silica to Preserve Glaciers Using Reinforcement Learning
Authors: Prabu Aadhav
Published: July 2021

Glaciers cover nearly 10 percent of the earth’s surface but are melting at an inexorable rate. According to the Pacific Standard magazine, the Arctic Sea ice has lost 80 percent of its volume since 1979. Antarctica’s ’Doomsday Glacier’ is melting faster and could raise global sea levels by two feet. As three-quarters of the earth’s fresh water is stored in glaciers, its melting depletes freshwater resources for millions of people. Glaciers also play a huge role in the climate crisis. Silica microspheres are promising materials to prevent glacier melting as it reflects most of the sun’s radiation. When spread in layers over the glacier, it can slow the rate of melt and aid in new ice formation. However, it is necessary to determine the ideal amount of silica to achieve the desired result with minimum environmental impact. This paper introduces a novel method SPF ICE to determine the optimal amount of silica based on glacier’s properties using reinforcement learning agents and a custom OpenAI Gym environment. The environment simulates a real-world model of a glacial setting using specific data, such as the glacier’s mass balance, temperature, and average accumulation and ablation. After testing the agents, the proposed solution reduced glacial melting by an average of 60.40% using the optimal amount of silica. The results indicate SPF ICE is a promising and cost-effective solution to curb glacier melting.
EffMoP: Efficient Motion Planning Based on Heuristic-Guided Motion Primitives Pruning and Path Optimization With Sparse-Banded Structure
Authors: Wen Jian , Zhang Xuebo , Gao Haiming , Yuan Jing , Fang Yongchun
Published: July 2021

To solve the autonomous navigation problem in complex environments, an efficient motion planning approach called EffMoP is presented in this paper. Considering the challenges from large-scale, partially unknown complex environments, a three-layer motion planning framework is elaborately designed, including global path planning, local path optimization, and time-optimal velocity planning. Compared with existing approaches, the novelty of this work is twofold: 1) a novel heuristic-guided pruning strategy of motion primitives is proposed and fully integrated into the state lattice-based global path planner to further improve the computational efficiency of graph search, and 2) a new soft-constrained local path optimization approach is proposed, wherein the sparse-banded system structure of the underlying optimization problem is fully exploited to efficiently solve the problem. We validate the safety, smoothness, flexibility, and efficiency of EffMoP in various complex simulation scenarios and challenging real-world tasks.

Initially, we evaluate and show the weaknesses of two popular schemes, Gope et al.'s and Feng Zhu et al.'s schemes; based on our investigation, their schemes fail to achieve several security features and cannot withstand various attacks. Later, we propose a new scheme to resolve the problem their schemes and provide the solution for the RFID security problem generically. Analyzes informal and formal are used to ensure that our proposal fulfills security properties and withstands various attacks.
Massimo Quaini e la geografia di avanguardia: dal Marxismo e geografia all’Anarchismo e geografia
Authors: de Marcos Valeria
Published: July 2021

Trying to understand the world to transform it, Massimo Quaini has introduced new methodological research approaches, giving shape to a geography focused on the real problems of his time. His most translated book, Marxism and geography (1974), has influenced on generations of geographers around the world. However, Quaini went further and, in his scientific life, approached the reading of Elisée Reclus and his anarchist geography. This article highlights the contributions of the most rebellious Italian geographer of his time, Professor Massimo Quaini.
Massimo Quaini: geografia storica, fonti, conoscenze territoriali e loro uso politico e socio-culturale

Published: July 2021

Quaini's commitment is aimed – with the development of the Gambian concept – towards the construction of a critical and operational historical geography (usable for the aware and sustainable management, institutional planning and socio-cultural use of territories), through innovative theoretical-methodological reflections and concrete case studies: with a focus on the landscape-territorial historicity and the heritage of regions and places, and openness to interdisciplinarity and local knowledge, integrating – with exemplary critical contextualization – the written and graphic documentary sources with those of the terrain.
Il ruolo dell’utopia, del mito e dell’immaginario nella concezione della geografia di Massimo Quaini
Authors: Surdich Francesco
Published: July 2021

Myth, utopia and the imaginary have represented fundamental categories of geographical thought, as Massimo Quaini highlighted in several of his contributions, which underlined their influence and importance for the history of geography in the construction and development of geographical concepts. The weight and role of these categories of interpretation of geographical reality were particularly important at the time of the great geographical discoveries in the process of opening the European horizon to new worlds, a complex process in which the geographical imaginary represented a stimulus and a push, as it happened for the genesis and development of the Colombian conceptual universe.
Massimo Quaini, la passione per la cartografia storica con uno sguardo rivolto al futuro
Authors: Poli Daniela
Published: July 2021

The essay traces back the scientific dialogue between the author and Massimo Quaini about the contemporary usefulness of the geographer-cartographer figure, perfected during the period of the great absolute monarchies. In this path, which ranges among memories, literature, poetry, the story of the elaboration of the Charter celebrating the historical-morphological identity of the Levanto territory drawn up during the elaboration of the Levanto PUC finds space. In the text, Quaini’s fundamental contribution emerges in highlighting the historical cartographer as a mediator of knowledge, an aspect that is necessary today to recover in order to create an urban planning account capable of putting at the centre of the project the place, in its various expressive forms, and the settled community.
Massimo Quaini, bricoleur. Su un libro che avrebbe potuto essere e non fu
Authors: Tanca Marcello
Published: July 2021

This article contains the text of an e-mail I received from Massimo Quaini in 2017. Through this mail he was answering to my invitation to participate in the fourth edition of “Dialoghi tra geografia e filosofia”, a ‘dialogic’ seminar I have been organizing since 2014 to enhance the discussion between geographers and philosophers. Due to his illness, unluckily he was unable to attend the conference but he wrote me an e-mail in which he invited me to write a book together, four-handed. This e-mail is one of the last documents ever written by Quaini: here we have many of his landscape ideas, as well as many thoughts on the identity and the future of geography, and much more. For this reason I thought making this mail public could be the best way to honour his memory.
Sulla geograficità della ecologia storica: contributi di Massimo Quaini
Authors: Cevasco Roberta , Moreno Diego
Published: July 2021

The paper identifies the main contributions of Massimo Quaini to the problems of historical ecology in its South-European developments and to the definition of geographic-historical microanalysis within geography. It is on this ground that the work of the naturalists/ecologists has most dialogued with his geographical epistemology, starting from the dissatisfaction with the macro-categories of the global scale, the decontextualization of geographic facts and the problems of the “second biologization of the environment”, and drawing new perspectives for geographical action starting from the interpretation of rural and historical-environmental heritage.

This contribution discusses the legacy of Massimo Quaini’s research in the field of postclassical rchaeology and, in particular, in the study of landscape and environment. Its active participation in the archaeological theoretical debate is highlighted through the analysis of his bibliography and experiences from the 70’s until his last works with the Territorialist Society and the Laboratory of Environmental Archaeology and History (LASA) of the University of Genoa.
Massimo Quaini e il viaggio: il ruolo della verticalità
Authors: Greppi Claudio
Published: July 2021

In the issue of Geotema dedicated to travel (“Travel as source of geographical knowledge”), in 1997, Massimo Quaini’s article topic was “The geographical invention of verticality: for the history of the ‘discovery’ of mountains”. It concerns a fundamental segment of the history of geographical knowledge, between eighteenth and nineteenth centuries, involving both the Old and New World: Saussure in the Alps and Humboldt in the Andes. He had already worked on this same topic in other occasions, investigating institutions like CAI in Italy, and mountain’s role in the ‘official’ geography. Such lectures mark a path that, I think, finds a theoretical output in 2006 Parma conference, dedicated to the “end of the travel”, where Quaini spoke about “Between Eighteenth and Nineteenth Century: the travel and the new paradigm of geography”: a rich and problematic lecture, opening to further researches. But perhaps before this point of arrival, the new paradigm, I would suggest to think on an idea offered by the Geotema article, where we read: “so, if we want to fully speak of discovering the mountains it will be necessary that the culture of the outside travellers meet that of the mountaineers”. Actually, in Quaini's last lecture I take into consideration, the one at Forte di Bard in September 2006, his attention shifts definitely on the figures of alpine travellers, who may encounter knowledge acquired from local culture.
Il filo da riannodare: Massimo Quaini, una letteratura per la geografia e una geografia per la letteratura
Authors: Gabellieri Nicola
Published: July 2021

With regard to the relationship between literary works and geographical studies, Massimo Quaini’s interest consolidated into a heuristic imprint whose originality has not yet been adequately enlightened. Through the analysis of his essays, the paper identifies some clues of his thought: methodologically, the need for a critical approach of ‘archeology of knowledge and sources’ to the writer’s profile; teleologically, the identification of the geographical factors inside the works as a tool for territorial enhancement; epistemologically, the use of literary topoi and metaphors as an interpretive key – together with the geographical-historical analysis – of the historical and current territorial dynamics.
Comparison of endocervical swabs to cultured isolates for the detection of antimicrobial resistance determinants in Neisseria gonorrhoeae

Background: The global emergence of antimicrobial resistance (AMR) in Neisseria gonorrhoeae to various antibiotics is a public health concern. To date, there have been no published South African studies that have compared the primary swab to the cultured isolates for the detection of N. gonorrhoeae AMR determinants. This study provides data on such a comparison. Methods: Paired endocervical swabs were collected from 307 pregnant women. The first swab was stored in an Amies charcoal transport media for culture assessment and the second swab was used for the molecular detection of resistant determinants. Specific targets (genes/plasmids/mutations) associated with resistance to penicillin, tetracycline, ciprofloxacin, spectinomycin, cefixime, azithromycin and ceftriaxone were detected from both the cultured isolates and the endocervical swabs. Results: Of the 307 samples tested in this study, only six samples tested positive for culture. A total of 24 samples tested positive for N. gonorrhoeae with the quantitative polymerase chain reaction (qPCR) assay. The six samples which tested positive for culture fell within the qPCR positives group. Since this study was designed to directly compare the culture swabs to the endocervical swabs for the detection of AMR determinants, the current analysis included only the six culture samples and six paired endocervical swab samples (n = 6). All six isolates were resistant to tetracycline and penicillin G while five of the six isolates were resistant to ciprofloxacin. All isolates were susceptible to the remaining antimicrobials. There was a 100% correlation between the cultured isolates and endocervical swabs for detecting the specific AMR determinants, conferring resistance to tetracycline, penicillin G and ciprofloxacin. Conclusion: Based on the findings of this study, tracking emerging patterns of resistance from the molecular level using only the endocervical swabs may serve as an attractive future research direction.

In the beginning of the COVID-19 pandemic in March 2020, by the decree of the Mayor of Moscow, the provision of dental services to the population was temporarily suspended, with the exception of diseases and conditions requiring emergency or urgent dental care. A Headquarters was established to coordinate the provision of emergency and urgent dental care for COVID-19 patients and for those who was in isolation during lockdown. The Moscow Healthcare Department has been organized an activity of mobile medical and nursing teams (MNT) to provide emergency medical care in the "dentistry" profle. All MNTs were equipped with portable dental equipment. The MNTs has been working for free within the framework of compulsory medical insurance. For the period from March 26 to June 16 – 2020, medical care was provided to 1501 patients, of which 294 with a confrmed diagnosis of COVID-19, including 57 children. The measures taken were of a temporary nature and were aimed at preserving the health of Moscow residents and preventing the further spread of the new coronavirus infection COVID-19 in Moscow.
