Published: April 2022

Los médicos residentes enfrentan cambios en el estilo de vida, adquisición de hábitos alimenticios inadecuados, influencia de modas, publicidad y necesidad de pertenecer a un grupo social, por lo cual se encuentran en riesgo de padecer sobrepeso y obesidad. Nuestro objetivo fue determinar el estado nutricional, los patrones de alimentación y la realización de actividad física de los médicos residentes del Hospital General de Luque del año 2019. Se realizó un estudio descriptivo, observacional de corte transversal en el que se evaluaron variables sociodemográficas, antropométricas, estado nutricional, patrón alimentario y actividad física. Se incluyó un total de 58 médicos residentes de los cuales 66% fueron del sexo femenino, y la edad promedio fue de 28,12 años. Según el IMC, la mayoría presentó sobrepeso (34,5%). En cuanto a los patrones de alimentación, la mayoría no cumplía con las recomendaciones de las Guías Alimentarias del Paraguay de consumir 3 frutas por día ni de evitar alimentos ricos en grasas, sodio y altos en calorías como lo son las comidas rápidas. Se observó que 49% no realizaba actividad física. Los médicos residentes del Hospital General de Luque presentaron en su mayoría exceso de peso, tenían un patrón alimentario inadecuado y no realizaban actividad física.

Authors: Pandharpurkar Apoorva , P. Deepak , V. Manjula B. S.
Published: April 2022

Background: India has the third highest number of people living with human immunodeficiency virus (PLHIV) population in the world. Health care personnel (HCP) are major risk group for acquiring HIV infection by accidental occupational exposure. Knowledge on post-exposure prophylaxis (PEP) holds the key to prevent new HIV infections and also helps in reduction of anxiety among HCP in case of accidental exposure. This study was designed to assess the awareness of PEP and to compare the levels of knowledge among various cadres of HCP.Methods: A cross sectional study was conducted on awareness of PEP among the health care personnel of sample size 360 in a tertiary care centre in urban South India. Universal sampling was done and data was collected for a period of three months. Analysis was done using the Epi info 7.2.Results: Knowledge of PEP among HCP was found to be 63.57%. Knowledge of PEP among groups of faculties, post graduate (PG) students, interns, nurses and lab technicians was found to be 73.5%, 70.9%, 62.8%, 56.9% and 42.2% respectively. There was poor knowledge among the most vulnerable groups i.e. nurses and lab technicians who handle the blood samples of number of PLHIV on a given day. There was a felt need among the faculty, PGs and interns for a refresher training every year on advances in HIV prophylaxis and treatment.Conclusions: This study has brought to light the lacunae in awareness of PEP for HIV among HCP. As India has a high prevalence of HIV, and occupational exposure is pretty much inevitable, there is a pressing need to plug the gaps in awareness of PEP.

Authors: Nunes Andréa Silveira Netto , Brandli Luciana Londero
Published: April 2022

No contexto urbano atual, é importante compreender os benefícios que espaços públicos integradores, como as Infraestruturas Verdes podem trazer às cidades e aos usuários dela. A cidade de Passo Fundo possui diferentes espaços públicos e três grandes parques na cidade, porém eles encontram-se ou em área nobre ou no centro da cidade, já o Parque Linear do Sétimo céu encontra-se em um bairro comum da cidade, rodeado por outros diversos bairros, o que o torna um objeto de estudo em evidência para análise neste trabalho. O objetivo deste estudo é verificar o impacto social da construção do Parque Linear do Sétimo Céu na cidade de Passo Fundo na época que o mesmo estava sendo construído. Para que isso seja alcançado, foi feita uma avaliação de um estudo de caso, realizado através de entrevistas de opinião de moradores da cidade sobre a construção do Parque Linear modelo de infraestrutura verde da região, localizado na Avenida Rui Barbosa, no Bairro Petrópolis, em Passo Fundo. Nesse sentido, foi feito um mapeamento das redondezas do bairro onde o Parque Linear do Sétimo Céu estava sendo construído dentro do contexto urbano, avaliando também aspectos como a renda mensal por família, gênero e faixa etária. Baseado na teoria, foi feita uma relação da aceitação dos cidadãos passo-fundenses que residiam em um dos três bairros do estudo para com a construção do Parque Linear do Sétimo Céu, com a renda, gênero e faixa etária. Os resultados demonstraram uma importante reflexão de como o modelo de urbanismo com Infraestrutura Verde pode ser positivo para os cidadãos que compõem uma cidade, estando eles, por sua vez, sujeitos a interação constante com outros elementos e infraestruturas que também regem o espaço urbano como um todo. A conclusão com este estudo de caso que o modelo de urbanização Verde que o Parque Linear representa nos modelos de urbanismo atual é que ele contribui para a diminuição da segregação social do espaço urbano na cidade, atendendo a diferentes segmentos da sociedade passo-fundense e aumentando a interação e troca de culturas e assim contribuindo para a integração social.

A arquitetura pode ser entendida como um processo contínuo de adaptação de usos e/ou indivíduos, tais adaptações requerem comumente ampliações, estas quando não previstas e/ou consideradas podem inviabilizar o uso dos espaços. É o caso do novo coronavírus, SARS-CoV-2, que tem o potencial de tornar os sistemas de ventilação natural em ambientes hospitalares inadequados, não apenas para os trabalhadores, mas também para as pessoas que transitam por esses ambientes, mesmo por um período limitado. Neste estudo, realizou-se modelagem 3D paramétricas para a análise da possível circulação do vírus SARS-CoV-2 no sistema de ventilação natural de um hospital construído para tratamento de pacientes infectados na pandemia de COVID-19. Realizou-se a modelagem da edificação em BIM, gerando modelos 3D do ambiente hospitalar utilizando o software Revit e posteriormente para fins de simulação, o software Autodesk CFD 2021. A avaliação considerou análises dimensionais de 0°, 45°, 90° e 180°. Foi considerada a análise dos padrões de ventilação natural nas superfícies interna e externa e a distribuição das janelas em relação à dinâmica de deslocamento do vírus SARS-CoV-2 pelo ar. Nestas simulações a velocidade do vento atingiu velocidades de até 2,1 m/s ao entrar no prédio pelas janelas abertas, quando em tato com o mobiliário o valor altera para 0,78 m/s. Este artigo proporciona insights sobre a possibilidade de contaminação por SARS-CoV-2 em ambientes hospitalares internos.

Актуальность исследования обусловлена, с одной стороны, снижением эффективности разработки месторождений углеводородного сырья традиционными методами, а с другой стороны, климатической повесткой, императивом которой является сокращение углеродного следа в процессе добычи. Мировой опыт показывает растущую востребованность газовых методов повышения нефтеотдачи, которые наиболее соответствуют достижению баланса между нефтеизвлечением и углеродным следом. Целью исследования является обоснование возможности применения газовых методов увеличения нефтеотдачи пласта для основных разрабатываемых залежей углеводородного сырья пластов Як-III-VII, Нх-I, Нх-III-IV. Объект: Ванкорское нефтегазоконденсатное месторождение, расположенное в Красноярском крае и входящее в состав Ванкорского кластера. Метод: расчет минимального давления смесимости по методикам, применяемым в российской и зарубежной практике. Результаты. С учетом особенностей процесса вытеснения нефти газовым агентом и основных факторов, влияющих на данный процесс и выбор газового агента (термобарические условия, геолого-физические характеристики пластов, физико-химический состав пластовых флюидов), были проведены расчеты минимального давления смесимости (Minimum Miscibility Pressure, MMP), при котором газ может полностью раствориться в пластовой нефти в результате многоконтактного процесса смешивания при пластовой температуре. Были обоснованы виды смешиваемости газа с пластовым флюидом для выбранных продуктивных пластов Ванкорского нефтегазоконденсатного месторождения, а также обоснована наибольшая эффективность углекислого газа в качестве газового агента для повышения нефтеотдачи по сравнению с азотом и углеводородным газом с концевых ступеней сепарации. Однако в силу современных инфраструктурных, производственных, макроэкономических условий деятельности добывающего предприятия данный проект не рентабелен.

Актуальность. Балансовые запасы энергетических углей Восточной Сибири уникальны по объемам, возможностям освоения и использования. Цель: оценка доступных ресурсов энергетических углей региона при выделении ресурсов низкокачественных и местных углей и перспектив и возможностей их использования для нужд энергетики. Объекты: месторождения угля, балансовые запасы, местные угли, тенденции поставок и перспективы использования углей, проекты сооружения объектов энергетики на угле. Методы: методы системного анализа: классификация, структурирование и реструктурирование, анализ, формализация и конкретизация. Результаты. Выполнена оценка ресурсов энергетических углей Восточной Сибири. Анализ тенденций потребления энергетических углей региона показал незначительный рост поставок на электростанции при относительно стабильных поставках прочим потребителям. Рассчитан потенциально возможный уровень доступных в перспективе ресурсов углей для нужд энергетики, составляющий около 400 млн т/год. В перспективе наиболее востребованным направлением использования углей останется энергетика. При анализе балансовых запасов энергетических углей выделена категория местных, особенностью которых является их удаленность от населенных пунктов и транспортных коммуникаций. Оценка перспективы вовлечения местных углей в хозяйственный оборот показала возможность их использования только в котельных и мелких ТЭС при минимальной конкуренции с другими видами топлива. Возможный коридор поставок восточносибирского угля определяется вариантом развития экономики. Минимальные уровни поставок соответствуют незначительному их росту, а максимальные – росту более чем в два раза за счет ввода в эксплуатацию ТЭС для экспорта электроэнергии. Расчётные объемы потребления углей экспортными ТЭС могут составить от 35 до 50 млн т. Потенциальные возможности добычи энергетических углей региона значительно превышают их востребованность. Результаты анализа ресурсов энергетического угля Восточной Сибири показывают их надежность на длительную перспективу как источника топлива для объектов энергетики.

The Value of Self-Care: “Health Enthusiasts” and Healthificated Consumption
Authors: Berdysheva Elena
Published: April 2022

From a common sense perspective health is an absolute value. However, even in European societies, with their well-developed institutional infrastructure of preventive healthcare, individuals need to be encouraged, or even forced, for practicing self-care. The Russian state is also interested to promote a healthy lifestyle and self-preservation behavior among the population. Nevertheless, sociological data demonstrate that Russians are more inclined to use their health than to save and increase it for the future. Sociologists give mainly structural explanations for health investments unattractiveness, while the individuals' recognition of the value of health remains outside their attention. This paper examines the deficits of an individual’s intrinsic motivation to invest in one’s health within a valuation framework, emphasising the constructed and fluid nature of the social worth of self-care in market societies. The Russian case exemplifies the local meanings behind the value of health investments in terms of gaining return from health as a capital, consumer good and personal value. An abductive analysis of 26 in-depth interviews with Russians who enjoy health investments (‘health enthusiasts’) reconstructs mindsets that make investing in one’s health attractive. Streamlined by the valuation framework, the study reveals three levels of self-care value: physical (body taming for self-maximisation); positional (the ability to achieve new health indicators through science-based self-management as a new precursor of social status); and transcendent (projecting the desired self in terms of authentic self-expression and autonomous sustainability). Empirics signify the involvement of ‘health enthusiasts’ into consumption of market products that have been marketized as “good for health”. These commodities praise the value of health, legitimize individual interest to it, ritualize health care practices and contribute to a more self-focused, autonomous, and resilient entrepreneurial self. “Health enthusiasts” begin experiencing health as an asset, an investment into vitality and personal productivity. They discover own human potential and practice self-care as a path of “returning to oneself”. The results of the study demonstrate that market driven cultivation of self-care value may produce a utilitarian approach to self among Russians. This approach increases the subjective value of self and supports preventive self-care that is in demand in Russia. At the same time, market driven individual obsession with health may increase social competition and disintegration.

European and national identity in the perceptions of modern Russian youth: the case of St. Petersburg
Authors: Viktorova Elena , Petrenko Daria , Vlasova Natalia , Shishkina Eugenia
Published: April 2022

The article deals with the problem of the formation of the identity of the modern Russian student youth in St. Petersburg. The study is relevant due to the insufficient formation of modern Russian identity and its value bases, as well as the need to study the influence of European values on the worldview of the modern Russian youth in the context of globalisation. The purpose of the study was to identify the level of European identity among the Russian youth, as well as the attitude of the youth of St. Petersburg to Russian and European identities, to the problems of European integration, mutual influence of the cultures. The young generation born in the new Russia after the collapse of the Soviet Union was formed under the influence of the emerging new Russian identity, as well as the European identity, Western values and the processes of globalisation. Students of St. Petersburg, historically the most European city in Russia, were selected as the target group of the study.

The method of in-depth interviews was used as the main research tool. The results of the study showed the great importance for young Russians of the concept of "European identity", as well as European values ​​and the European way of life, that confirms the assumption preceding the study about the significance of European influence on the worldview of modern youth in the context of globalisation. The attitude of the surveyed youth towards Russian identity is less positive, being consistent with the researchers' statements about the lack of clarity regarding the concept of "Russian identity" and its basic values. The limitation of the study is that the sample included only students from St. Petersburg, and therefore its results are difficult to extrapolate to other regions of Russia, due to the special position of the city. The results of the study are preliminary in nature, allowing to identify the most significant trends in the formation of identity among today's youth, that will serve as the basis for further research.

The analysis of the study data showed that the European project of identity formation is more attractive to the surveyed youth than the Russian project of identity formation.

A descriptive research design was employed in this study. The respondents of the study were the 123 severely wasted and 400 wasted learners from Kinder to Grade VI of Malaban Elementary School, School Year 2018-2019. Based on the results of the study after the GPP utilization through SBFP, the nutritional status of the learners in terms of BMI showed improvement from severely wasted to wasted, and from waste to normal, some were from severely wasted to normal, together with their height and weight. Likewise, an improvement was also observed in the academic performance of the learners. Consequently, the GPP utilization through SBFP has positive implications on the nutritional status as indicated in the BMI, height, weight and academic performance of the learners. Hence, the researcher recommended that GPP needs to continue for it helps the schools in achieving the goals of the government in promoting and maintaining health and wellness among Filipino learners, for malnutrition is one of the biggest problems encountered by our country that affects the academic performance of the learners.
Método triplo para estimativa anual de luz natural (EALN) usando radiosidade
Authors: Claro Anderson
Published: April 2022

Além do conforto visual humano e estética, a luz natural tem importante papel no consumo de energia elétrica, por permitir substituir o uso de luz artificial ao longo dos dias. Hoje existe a Simulação Dinâmica usando Arquivos Climáticos digitais, que descrevem característica típica anual da disponibilidade de radiação e luz, em muitas localidades do planeta. Esta simulação usa o conceito de Daylight Coefficient (DLC), que associa à determinadas porções do céu a quantidade de luz que chega a pontos dos planos de ambientes, permitindo estimar disponibilidade diária/horária de luz natural durante um ano típico. Propõe-se aqui o Coeficiente de Radiosidade (CR), relacionando Iluminância inicial, de uma porção de plano, num ambiente com Iluminância parcial que, após várias inter-reflexões, chegam a outras porções de planos do ambiente, partindo daquela porção inicial. Apresenta-se o conceito de Estimativa Anual de Luz Natural – EALN, que propõe uma abordagem tríplice baseada na Radiosidade e usando o Coeficiente de Radiosidade, o Daylight Coefficient numa versão desenvolvida para Radiosidade e também o novo Conceito de Radiosidade Plena (RP), este usando ciclos integrais de Radiosidade no método clássico, de acordo com uma análise do ambiente que determina qual dos três métodos é mais rápido para a circunstância do projeto. Os três métodos conduzem aos mesmos valores de EALN, como é demonstrado, otimizando o tempo de estudos, além de outras vantagens. Modelos simulados pelos três métodos em diferentes graus de resolução mostram a consistência e confiabilidade da abordagem, como se demonstra nos resultados obtidos.

The oscillatory motion in nonlinear nanolattices having different interatomic potential energy functions is investigated. Potential energies such as the classical Morse, Biswas – Hamann and modified Lennard – Jones potentials are considered as interaction potentials between atoms in one-dimensional nanolattices. Noteworthy phenomena are obtained with a nonlinear chain, for each of the potential functions considered. The generalized governing system of equations for the interaction potentials are formulated using the well-known Euler – Lagrange equation with Rayleigh’s modification. Linearized damping terms are introduced into the nonlinear chain. The nanochain has statistical attachments of $40$ atoms, which are perturbed to analyze the resulting nonlinearities in the nanolattices. The range of initial points for the initial value problem (presented as second-order ordinary differential equations) largely varies, depending on the interaction potential. The nanolattices are broken at some initial point(s), with one atom falling off the slender chain or more than one atom falling off. The broken nanochain is characterized by an amplitude of vibration growing to infinity. In general, it is observed that the nonlinear effects in the interaction potentials cause growing amplitudes of vibration, accompanied by disruptions of the nanolattice or by the translation of chaotic motion into regular motion (after the introduction of linear damping). This study provides a computationally efficient approach for understanding atomic interactions in long nanostructural components from a theoretical perspective.
The Elliptic Integral Machine: A Collision-based Model of Computation
Authors:   Universidade Federal do Pampa, Melnik I. A. C.
Published: April 2022

In this work we will show how any elliptic integral can be computed by analyzing the asymptotic behavior of idealized mechanical models. Specifically, our results reveal how a set of circular billiard systems computes the canonical set of three elliptic integrals defined by Legendre. We will treat these Newtonian systems as a particular application of the billiard-ball model, a ballistic computer idealized by Eduard Fredkin and Tommaso Toffoli. Initially, we showed how to define the initial conditions in order to encode the computation of a set of integral functions. We then combined our first conclusions with results established in the 18th and 19th centuries mostly by Euler, Lagrange, Legendre and Gauss in developing the theory of integral functions. In this way, we derived collision-based methods to compute elementary functions, integrals functions and mathematical constants. In particular, from the Legendre identity for elliptic integrals, we were able to define a new collision-based method to compute the number $\pi$, while an identity demonstrated by Gauss revealed a new method to compute the arithmetic-geometric mean. In order to explore the computational potential of the model, we admitted a hypothetical device that measures the total number of collisions between the balls and the boundary. There is even the possibility that the methods we are about to describe could one day be experimentally applied using optical phenomena, as recent studies indicate that it is possible to implement collision-based computation with solitons.

Abstract: Background: Of the many side effects suffered by cancer patients, those related to cognitive performance have become increasingly prominent in clinical practice. We know that chemotherapy generates a series of side effects, such as nausea and vomiting, alopecia, and so on, which can be counteracted by complementary medication. However, in the case of post-chemotherapy cognitive impairment, or chemo brain, these cannot be controlled with drug therapies. However, before any intervention can be considered, it is necessary to know exactly what cognitive impairment is being triggered. For this reason, we decided to study the cognitive status of breast cancer patients. Methods: analytical, prospective, three-measure longitudinal, intrasubject unifactorial, non-probabilistic and accidental assignment study. The sample came from the Medical Oncology Department at Hospital de Salamanca, in Spain. Cognitive function (Trail Making Test and Stroop Test) was established as the primary variable; the presence of sleep disorders (Insomnia Severity Index, ISI) and anaemia (haemoglobin levels in blood) were analysed as secondary variables, in addition to sociodemographic variables (age, stage, type of carcinoma, radiotherapy, menopause, social support network, marital status, years of schooling and employment status). Results: We recruited 151 individuals according to the selection criteria. We can confirm that factors including anaemia, menopause, patient support network and marital status, years of schooling, and employment status did affect the cognitive performance of the patients in active chemotherapy treatment in the study. In contrast, sleep disorders, age, radiotherapy treatment, stage of disease, and type of carcinoma did not affect the cognitive performance of the cancer patients. Conclusions: Chemotherapy does impact the cognitive performance of breast cancer patients.

The electronic structural evolution of LLM-105 crystal and the (101) plane of LLM-105 crystal under different pressures is investigated by the density functional theory (DFT) calculations and the surface properties of seven low-Miller-index planes of LLM-105 crystal were investigated in this study. The result demonstrates that the surface energy of (101) plane of LLM-105 is much smaller when compared with other low-Miller-index planes of LLM-105.In order to further investigate the stability of crystal structure and (101) plane of LLM-105 under different pressures, a series of pressures ranged from 0 GPa to 55 GPa were applied during the DFT calculation, and the result shows that the electronic structures of LLM-105 crystal and the (101) plane changed with the increase of external pressure and the evolution process of (101) plane is different from that of LLM-105 crystal structure.

Published: April 2022

The gasification of sugarcane cutting waste (RAC) is a process that occurs in a gasifier where the transformation of this raw material into a solid-state and a gasifying agent with a moderate calorific value occurs, thanks to the application of heat. Under restricted oxygen levels, we can say that several styles of air gasifiers, water vapor, oxygen, and hydrogen have a performance that can be analyzed and categorized by their performance to avoid damage to the environment. The objective of this article is based on the mathematical development of gasification of cane cutting waste; it was carried out as a transformation of the primary fuel into a stream of gases whose main components are CO2 and H2, which can be separated relatively easily by their concentrations, and available pressures and in some cases in their temperatures; which helped to identify the second-order reaction in the transformation and improvement of the process; applying to the optimization of development in the capture of carbon dioxide, contributing to the reduction of greenhouse gases.

Objective. To study the effectiveness of gray-scale ultrasound imaging (according to O-RADS) and contrast-enhanced ultrasound (CEUS) in the diagnosis of ovarian tumors. Patients and methods. A total of 100 patients with ovarian neoplasms were observed, in whom the diagnosis was confirmed by morphological examination. Patients were divided into two groups: group 1 (n = 67) met the O-RADS 2-3 criteria (low risk of malignancy), and group 2 (n = 33) met the O-RADS 4-5 criteria (intermediate and high risk of malignancy). Results. The mean age of patients was 32.7 ± 6.72 years. Sensitivity (Se) of O-RADS was 84.8% (95% CI: 80-88%), specificity (Sp) of O-RADS was 88.1% (95% CI: 85-91%). Sensitivity of CEUS was 90.9% (95% CI: 85-95%), specificity of CEUS was 92.5% (95% CI: 89-97%). In ROC analysis of sensitivity and specificity of CEUS, AUC = 0.895; in analysis of sensitivity and specificity of O-RADS, AUC = 0.744 (p ≤ 0.005). Conclusion. Given its high sensitivity and specificity, the O-RADS stratification system should be used in the interpretation of ultrasound imaging of any ovarian neoplasm. The CEUS can be used as an alternative to other, significantly more expensive contrast-enhanced imaging techniques, such as CT or MRI, in the differential diagnosis of “complicated” ovarian tumors.

Objective. To study the efficacy and safety of the use of vitamin and mineral complex (VMC) “Miteravel Plus” and women’s compliance during the preconception period and pregnancy. Patients and methods. A prospective study (n = 1793) was conducted to assess the safety and tolerability of VMC “Miteravel Plus”, containing vitamins, micronutrients, and polyunsaturated fatty acids, as well as compliance among pregnant women and women planning pregnancy. The duration of VMC administration was at the discretion of pregnant women and their attending physician. A three-stage questionnaire was carried out during the study: before the beginning of VMC intake, one month after the end of VMC intake, and within 1 month after delivery. Results. 12.77% of pregnant women took the medication for more than a month; 14.05% of patients – for 2 months; 73.17% of patients – for 3 months or more. During the third stage of questionnaire, 72.58% (n = 1281) of women didn’t have anemia; 94.14% (n = 1688) of pregnant women underwent emergency delivery; 99.67% (n = 1787) of women were satisfied with the tolerability of “Miteravel Plus”. Conclusion. By means of micronutrient correction during the preconception period and pregnancy, it is possible to significantly reduce the risk of giving birth to children with various diseases and minimize the likelihood of complications during pregnancy and the postpartum period in women.

Objective. To examine the characteristics of pregnancy and to assess the efficacy of intranasal recombinant interferon (IFN) alpha-2b in pregnant women with COVID-19 and in newborns with perinatal exposure. Patients and methods. We examined 200 pregnant women hospitalized with a novel coronavirus infection between May 2020 and January 2021, and 125 neonates born from these pregnant women. Maternal age ranged from 19 to 37 years. The number of first births was 37 (18.5%). All pregnant women were divided into 3 groups by gestational age: Group 1 included 27 (13.5%) pregnant women who had coronavirus infection in the first trimester of pregnancy, Group 2 included 48 (24%) pregnant women who had coronavirus infection in the second trimester, and the Group 3 included 125 (62.5%) pregnant women who had coronavirus infection in the third trimester. Results. The frequency of obstetric complications after novel coronavirus infection increases with gestational age (from 7.4% in the first trimester to 28% in the third trimester). Pregnant women in the second trimester have an increased risk of developing severe forms of novel coronavirus infection and pneumonia (up to 70.8%). The use of recombinant interferon (IFN) alpha-2b in newborns with perinatal exposure to COVID-19 has a preventive effect. Among neonates from COVID-positive mothers who received intranasal recombinant IFN alpha-2b for the prevention only 7.7% of children developed COVID-19, whereas in the group of neonates who did not receive this preventive medicine 20% of children contracted the disease. Conclusion. The use of intranasal recombinant IFN-based medicine (Grippferon®, nasal drops) in pregnant women with COVID-19 for the treatment and in newborns with perinatal exposure to novel coronavirus infection for the prophylactics has a statistically significant positive effect.

Objective. To evaluate the efficacy of Intraovarian autoplasmotherapy (platelet-rich plasma/PRP) in the activation of ovarian function in patients with diminished ovarian reserve and “poor” response in the in vitro fertilization (IVF) cycles, as well as its influence on the quality of life. Patients and methods. A total of 120 patients with diminished ovarian reserve and a history of IVF cycle failure who refused to use donor oocytes were included in the study. All patients underwent intraovarian PRP therapy based on the proprietary technology. The quality of life, the ovarian function, and the results of the embryo stage in the IVF cycle were monitored for 6 months. Results. The conducted study demonstrates a positive effect of intraovarian PRP therapy on the functional state of the ovaries and on the results of the embryo stage in IVF in the cohort of patients with diminished ovarian reserve and “poor” response in previous unsuccessful IVF cycles. The findings also indicate changes in the quality of life, an improvement in sexual function, and positive dynamics in the emotional state. Conclusion. Intraovarian PRP therapy allows patients with infertility and diminished ovarian reserve to avoid using donor oocytes and to obtain their own genetic material. This technology has a positive effect on the quality of life, having a certain anti-age effect in all groups of examined women, the duration of which has yet to be clarified.
