Effect of Adjuvant Chemotherapy is Responsible for Decreasing Segmental and Total BMD in BC Postmenopausal Women
Authors: Movva Srileela , Konijeti Srinivasa Rao
Published: December 2021

Background: Women with breast cancer are at increased risk for the development of osteoporosis and skeletal fractures, as consequences of aromatase inhibition or chemotherapy-induced ovarian failure. We investigated the effect of adjuvant chemotherapy on biochemical markers of bone formation and resorption as well as on bone mineral density (BMD) of non-metastatic breast cancer (NMBC) postmenopausal Egyptian women. Methods: We followed 100 newly diagnosed women with T1-3 N0-2 M0 breast cancer, who had a mean age (±SD) of 55.06±8.78 year, before and after receiving 6-cycles of CAF chemotherapy treatment protocol. All participant women were subjected to blood biochemical analysis for determining serum levels of: erythrocyte sedimentation rate, calcium, alkaline phosphatase (ALP), bone specific alkaline phosphatase (S.ALP), Osteocalcin, carboxytelopeptide of collagen type I (CTx-I), 25-Hydroxyvitamin D, Parathyroid Hormone (PTH) and tumor marker CA15-3. Segmental and total BMD were also investigated using Dual X-ray Absorptiometry technique. Results: We found ALP, S.ALP, and CTx-I levels were significantly lower (p<0.001), while PTH levels to be significantly higher for all women after chemotherapy as compared to their initial state before chemotherapy. Both segmental and total BMD, and consequently T- and Z-Scores after chemotherapy were significantly (p<0.01) lower than their levels before chemotherapy. We developed prediction mathematical formulae for spine, pelvis and total BMD for all women before and after chemotherapy. Conclusions: Adjuvant chemotherapy is responsible for decreasing both biochemical markers of bone formation and resorption as well as for decreasing segmental and total BMD in NMBC postmenopausal Egyptian women. We believe the mathematical formulae developed on basis of the two individual variables Age and BMI can be useful for assisting the clinician to frequently monitor bone health status of breast cancer patients in similar conditions.

Published: December 2021

Giant cell tumours (GCT) are usually benign, locally aggressive tumours. They tend to occur in long bones and rarely in small bones, with an incidence rate of 1.2 to 2.4% in the bones of the foot. The objective is to present a unique case in the literature of a GCT that only affected the first cuneiform. We present the case of a 35-year-old male patient seen at Hospital General de México (HGM) with seven months history of pain and increased volume in the medial region of the right foot, with X-ray and MRI images consistent with GCT in first cuneiform of the right foot. The excisional biopsy confirmed GCT. The definitive treatment consisted of curettage, cryotherapy with nitrogen and heterologous bone graft placement. Evolution was satisfactory, with no pain, no volume increase, normal gait and radiographic bone graft integration. Follow-up was at six years.

Authors: Azab Azab Elsayed , Algridi Munira Ammar
Published: December 2021

Background: Humans are exposed to aluminum from the mouth, nose and epidermal route inducing toxic effects. Accumulation of aluminum has been associated with a variety of pathologies such as anemia, osteodystrophy, joint diseases, muscular weakness, and Alzheimer’s diseases Fenugreek extracts have been shown to be neutralizing of free radicals and enhancing antioxidant status. Objectives: The present study aimed to evaluate the ameliorative effects of fenugreek seeds against hematotoxicity induced by Aluminum chloride in male rabbits. Materials and Methods: This study included twenty-four adult male rabbits, which were divided into 4 groups, 6 rabbits for each. Group I (control group): Animals were provided with tap water and fed with a normal diet for 30 days. Group II (Fenugreek seeds powder group): Fenugreek seeds powder was given to rabbits in food at a dose of 10 g per kilogram of diet weight/kg of body weight/day for 30 Days. Group III (Aluminum chloride (ALCl3) group): Rabbits were treated orally with 150 mg/kg BW of AlCl3/day for 30 consecutive days. Group IV (Aluminum chloride/fenugreek co-administered group): Fenugreek seeds flour was added at a rate of 10 g per kilogram of diet weight, and rabbits were treated orally with 150 mg/kg BW of AlCl3/day for 30 consecutive days. At the end of the experiment and 24 hours after the last dose, all animals were anesthetized with ether and blood samples were collected by heart puncture. Results: The results of the study showed that the treatment of male rabbits with aluminum chloride resulted in a significant decrease (P<0.01) in RBCs count, hemoglobin concentration, hematocrit value, MCV, MCH, and MCHC as compared to the control group. While there was a significant increase (P<0.01) in WBCs count, lymphocytes, and monocytes percentages and a significant decrease in granulocyte percentage when compared with the control group. Co-administration of fenugreek seeds powder and AlCl3 significantly improved all haematological parameters. Conclusion: The results showed that the administration of rabbits with aluminum chloride caused a hematotoxicity, and co-administration of fenugreek seeds powder with AlCl3 alleviate the hematotoxicity induced by AlCl3. The use of fenugreek seeds powder by humans can be considered beneficial in the alleviation of hematotoxicity. It is recommended that humans exposed to AlCl3 should be advised to take fenugreek seeds powder as a rich source of antioxidants to prevent hematotoxicity induced by AlCl3. Further studies are necessary to elucidate the exact mechanism of the anti-hematotoxic effect of Fenugreek seeds powder and the potential usefulness of fenugreek seeds powder as a protective agent against AlCl3 induced hematotoxicity in clinical trials.

Authors: Mijangos Pulido Víctor Manuel , De Anda Sánchez José
Published: December 2021

En México son muchos los ejemplos de plantas de tratamiento de aguas residuales municipales (PTARM) aban¬donadas o que se encuentran trabajando en condiciones precarias, debido principalmente a los elevados consumos de energía y a los altos costos de mantenimiento y operación (MyO). El objetivo de este trabajo de investigación es el de desarrollar una metodología para la evaluación de 26 PTARM dentro del estado de Jalisco en México fuera de operación o en condiciones de abandono, con la finalidad de seleccionar una de éstas para su recuperación y reconversión tecnológica a un sistema pasivo de tratamiento y con costos reducidos de MyO. El método desarrollado consta de 20 reactivos que evalúan diferentes criterios utilizando escalas de Likert. A cada reactivo le son asignados pesos ponderados de acuerdo con un orden de importancia. La evaluación favoreció aquellas PTARM que requieren un menor presupuesto para su intervención y utilizan sistemas pasivos de tratamiento. Se encontró que el método desarrollado es replicable y adaptable a otras regiones con una problemática similar, y abre la posibilidad, en ciertos casos, de recuperar paulatinamente la infraestructura existente. A través de este proceso se identificó y se logró la recuperación de una PTARM con una reducida inversión de recursos públicos.

New serial concatenation schemes based on the multithreshold decoders and di- vergent principle for the convolutional self-orthogonal codes under Gaussian channels are proposed. Using both binary and symbolic decoders on the second decoding stage of the convolutional codes are considered. Simulation results are indicated the higher performance characteristics of the proposed cascade schemes on majority decoders in comparison with clas- sical schemes based on the Viterbi algorithm and Reed-Solomon codes. A moderate increase in decoding delay during concatenation is revealed. It is determined by the absence of the need to use traditional two-dimensional concatenated structures.
A MODIFIED METHOD OF SOLVING THE PRESSURE–RATE DECONVOLUTION PROBLEM FOR IDENTIFICATION OF WELLBORE–RESERVOIR SYSTEM
Authors:   N.N. Krasovskii Institute of Mathematics and Mechanics (IMM UB RAS), Ural Federal University, Vasin Vladimir , Toussaint Fabrice ,   Jurtuna Energy Ltd
Published: December 2021

In the paper, the method suggested in [5] for solving the pressure–rate deconvo- lution problem was modified with implementation for the synthetic (quasi-real) oil and gas data. Modification of the method is based on using the additional a priori information on the function v(t) = tg(t) in the logarithmic scale. On the initial time interval, the function is concave and its final interval is monotone. Here, g(t) is the solution of the basis equation (1). To take into account these properties in the Tikhonov algorithm, the penalty function method is used. It allowed one to increase the precision of the numerical solution and to improve quality of identification of the wellbore–reservoir system. Numerical experiments are provided.

Authors:   Penza State University, Smirnov Yu. G. , Martynova V. Yu. , Moskaleva M. A. , Tikhonravov A. V. ,   Lomonosov Moscow State University
Published: December 2021

A modified method of separation of variables is proposed for solving the direct problem of diffraction of electromagnetic wave by multilayer dielectric gratings (MDG). To apply this method, it is necessary to solve a one-dimensional eigenvalue problem for a 2nd- order differential equation on a segment with piecewise constant coefficients. The accuracy of the method is verified by comparison with the results obtained by the commercially available RCWA method. It is demonstrated that the method can be applied not only to commonly used MDG elements with one line in a grating period but also to potentially promising MDG elements with several different lines in a grating period.

The reverse engineering problem of determining the layer thicknesses of deposited optical coatings from on-line monochromatic measurements is considered. To solve this inverse problem, non-local algorithms are proposed that use all the data accumulated during the deposition process. For the proposed algorithms, the accuracy of solving the inverse problem is compared in the presence of random and systematic errors. It is shown that in the case when the measured data contains only random errors, the best accuracy is provided by the algorithm based on minimizing the discrepancy functional. In the case of systematic errors, the advantage of one the algorithms based on minimizing the variance functionals is demonstrated. Key words: inverse problems, reverse engineering, optical coatings, thin films.
Ultrasonic Evaluation of Porosity in Out-of-Autoclave Carbon Fiber–Reinforced Polymer Composite Material
Authors: Samaratunga Dulip , Severino Joseph , Kenderian Shant
Published: December 2021

Ultrasonic longitudinal wave propagation is studied in out-of-autoclave (OoA) carbon fiber–reinforced polymer composite material with varying levels of porosity contents. A combination of cure pressures and a solvent is used to produce specimens with void contents in the range of 0% to 22%. Ultrasonic measurements are made in through-transmission mode, and the data is processed to study various aspects of wave interaction with porosity in OoA specimens. The specimens with a wide range of void contents have enabled the study of broader trends of ultrasonic center frequency, wave velocity, and attenuation with respect to porosity. Results show ultrasonic center frequency and wave velocity are decreased linearly as the void content increases. The relationship of ultrasonic wave attenuation can be approximated by a logarithmic relationship when considering the full range of void content studied. Strength measurements of specimens with varying void contents are made using the flatwise tensile (FWT) test. It is observed that the strength rapidly decreases with increasing porosity. Correlations made between FWT strength, ultrasonic wave velocity, and attenuation are best described by logarithmic relationships. The data shows a potential for inferring strength knockdowns due to the presence of porosity based on ultrasonic measurements.

Lisbon’s presidency came at a difficult time in the EU’s history, marked by a great number of internal and external risks and challenges. The Portuguese diplomacy, in cooperation with the EU’s governing bodies, has invested substantial efforts to solve political and economic problems arising from the coronavirus pandemic and to prepare the EU member states for a post-COVID era. However, these attempts to overcome “the European fatigue” have not been entirely successful.
“Some deputies hesitated until the last moment.” On the road to Ukrainian independence
Authors: KRUTIKOV Anton
Published: December 2021

The reluctant alliance between Ukrainian nationalists and the Communist Party and economic nomenklatura in August 1991 was one of the key factors in the declaration of Ukrainian independence. The Ukrainian political class preserved its monolithic character, which was reflected in the decorative and mostly formal changes that took place in the country after 1991. Instead of a profound transformation of the political system and structure of the political power, Ukrainian society received essentially the same set of institutions, political practices and actors. Personal interests of Ukrainian elites, guided by the instinct for self-preservation, played a decisive role.

Published: December 2021

One of many possible ways of preventing Early Childhood Caries (ECC) is by removing tooth debris. Fluoride tooth paste usage by children under 3 years old must follow recommended quantity, because of its possibility of being ingested which then might cause fluorosis. Lysozyme as an active element in a toothpaste is able to mediate bacterial aggregation and inhibit bacterial adhesion and also activate bacterial autolysin by destructing bacterial cell wall. This study aimed to compared  Streptococcus mutans antimicrobial activity of non-fluoride lysozyme toothpaste of various concentration such as 0.025, 0.05, 0.1, and 0.2 %. This was an experimental research with post test only design. The tested tooth paste was lysozyme-contained with 0.025, 0.05, 0.1 and 0.2% concentrations. Children tooth paste containing fluoride, enzyme tooth paste and 0.2% chlorhexidine became the positive control. Test of S. mutans antibacterial activity used 3 methods: disc diffusion, well, and microtiter plate method. Analytical test used Anova one way with Bonferoni post hoc and p<0.05 significant level. The results showed that all concentrations of lysozyme tooth paste had inhibitory effect on the growth of S. mutans (p<0.05). The highest mean of  S. mutans antibacterial activity in lysozyme tooth paste were on 0.1 and 0.2% concentrations. Conclusion stated that 0.1% concentration of lysozyme tooth paste can be used as an alternative tooth paste for children under 3 years old

Published: December 2021

Este artigo descreve os resultados parciais de uma pesquisa de mestrado, cujo objetivo foi verificar se existe correlação entre os traços de personalidade e o comportamento financeiro das pessoas. A pesquisa buscou responder à seguinte questão-problema: Quais os traços de personalidade que podem estar relacionados ao perfil financeiro de adultos de uma cidade do estado do Rio de Janeiro? Para identificar os traços de personalidade e o perfil financeiro dos 72 participantes, aplicou-se, por meio de uma pesquisa Survey, dois questionários: um com o propósito de diagnosticar se o participante apresenta perfil financeiro Endividado, Equilibrado Financeiramente ou Investidor, e o da teoria Big Five, que é o modelo mais pesquisado e apresenta os traços de personalidade em cinco grandes fatores gerais (conscienciosidade, abertura a novas experiências, extroversão, afabilidade e neuroticismo). Os dados foram analisados através do software Survio, sob a técnica de Análise de Conteúdos. Os sujeitos da pesquisa revelaram um perfil financeiro equilibrado com traços de personalidade Conscienciosidade. Entende-se que ao identificarem seu perfil de personalidade as pessoas poderão compreender melhor as suas emoções, seus pontos fortes e fracos, e passarão a fazer escolhas financeiras mais seguras e equilibradas. A identificação do perfil de personalidade pode representar também um avanço significativo no desenho de programas de Educação Financeira visto que durante muito tempo considerou-se que as habilidades numéricas tinham efeito sobre o comportamento financeiro das pessoas, porém estudos identificaram que não basta ter domínio da matemática, haja visto que habilidades não cognitivas como autocontrole, conscienciosidade e otimismo têm impacto significativo nesse tipo de comportamento.

Authors: Bramasta Bima , Nuryananda Praja
Published: December 2021

The Papua issue is a criticism directed at the Indonesian government which is often raised by Pacific countries in the United Nations session, especially by the countries of Fiji, Vanuatu and also the Solomon Islands regarding their views on Papua which is part of Indonesia. Feeling a little swayed by the criticism, the Indonesian government then responded by providing foreign aid which had a motive in it, namely to reduce criticism regarding the Papua issue. Foreign aid carried out by the Indonesian government is implemented in the Triangular South-South Technical Cooperation (KSSY), where this SSTC itself will be a milestone in the strategy to reduce criticism from Fiji, Vanuatu and Solomon Islands regarding the Papua issue. The research method used in this journal is a qualitative-descriptive research method, where this method will assist the author in describing the results of this journal by better describing the mechanism and course of a foreign aid process implemented in SSTC to reduce the issue of Papua. The data to be used comes from in-depth interviews with resource persons, as well as from academic journal literature, the media, and official government data which includes books and official annual reports from the government. The results of the research obtained will explain the results of the foreign aid process that was able to reduce the Papua issue raised by Fiji, Vanuatu and Solomon Islands.

Environmental issues have become a fairly important topic of discussion in the last few decades. These environmental issues have attracted a lot of attention from local to global levels. REDD + contains measures designed to reduce greenhouse gas emissions due to deforestation and forest degradation in the presence of financial incentives. In environmental diplomacy between Indonesia and Norway, the REDD + scheme aims to reduce pollution levels according to targets and within a certain time period. In analyzing Norway's environmental policy and its involvement in global environmental cooperation, market-based environmental policy instruments can be used. In market-based environmental policy instruments there is a carbon trading mechanism to evaluate the REDD + mechanism in 2015-2020. REDD + implementation in Indonesia is carried out with the existence of a carbon market that uses a cap and trade mechanism, which results in the form of carbon credits that can be disbursed into financial incentives. The funds can be used to reduce deforestation and forest degradation, as well as for the conversion of peatlands in Indonesia.

In 2018, the world of global waste trade received a major shick that has an impact to both waste exporting countries and waste importing countries, and that was the closure of waste imports by China, which was the largest recipient country at that time through National Sword Policy. Exporting countries were forced to duvert  their waste to the recipient countries that have not implemented new policies related to the imported waste such as Indonesia. As a result, Indonesia received a significant increase imported waste and cause a negative impact on various sectors, one of which was the environment sector. This then triggered some parties who have concerns regarding environmental issue such as ECOTON to resolve this issue by pressing the government to make new policies to stop imported waste that continues to degrade the environment.the author use a qualitative-descriptive method so that the authors can explain in detail and systematically the role of ECOTON in foreign policy making by using the theory of the direct role of NGOs in foreign policy making as the basis.

This paper discusses the implementation of Indonesian parliamentary diplomacy when Indonesia became the leader of the ASEAN Inter-Parliamentary Assembly (AIPA) (2011-2012). In the same period, Indonesia also assumed the chairmanship of the Association of South East Asian Nations (ASEAN). Developed from the concept of multi-track diplomacy and total diplomacy, the authors highlight how the House of Representatives of Republic Indonesia (DPR-RI) plays a role in a track 1½ diplomacy. The authors argue that DPR-RI's active participation is essential to oversee national compliance on international legal norms and rules through the case of AIPA.

The acceleration and deceleration rates vary from one vehicle type to another. The same vehicle type also exhibits variations in acceleration and deceleration rates due to vast variation in their dynamic and physical characteristics, ratio between weight and power, driver behaviour during acceleration and deceleration manoeuvres. Accurate estimation of acceleration and deceleration rates is very important for proper signal design to ensure minimum control delay for vehicles, which are passing through the intersection. The present study measures acceleration and deceleration rates for four vehicle categories: Two-wheeler, Three-wheeler, Car, and Light Commercial Vehicle (LCV), by using Open Street Map (OSM) tracker mobile application. The acceleration and deceleration rates were measured at 24 signalized intersection approaches in Hyderabad and Warangal cities. The study also developed acceleration and deceleration models for each vehicle type and the developed models were validated based on field data. The results showed that the predicted acceleration and deceleration models showed close relation with those measured in the field. The developed models are useful in predicting average acceleration and deceleration rate for different vehicle types under mixed and poor lane disciplined traffic conditions.

Published: December 2021

Introducción: El hallazgo de hematoma intramural intestinal resulta rara, debido a múltiples factores, iniciando por su su baja incidencia,1 de cada 2500 pacientes en tratamiento con warfarina. Su aparición se asocia en un 90% a traumatismos abdominales, existiendo pocos casos reportados en relación a  sobredosis de anticoagulantes. Es causa altamente infrecuente de dolor abdominal agudo, pero se convierte en un diagnóstico diferencial a tomar en cuenta en paciente con antecedentes de anticoagulación.  En casos espontáneos su localización es más frecuente en el yeyuno (71.6%) seguido del duodeno (29.8%). Objetivo: Reportar este raro hallazgo radiológico. Metodología: En el presente artículo detallamos el raro hallazgo radiológico mediante tomografía computarizada de un hematoma intramural en intestino delgado específicamente en segunda y tercera porción del duodeno relacionado a anticoagulación; a partir del relato de un caso clínico reportado. Conclusión: El reporte de hallazgos radiológicos de entidades raras como lo es el hematoma intramural duodenal no traumático es importante y nutritivo en cuanto a evidencia científica, ampliando el abanico de opciones en pacientes con dolor abdominal no especificado con sospecha de sobredosis de anticoagulación
Вплив міжнародних договорів і практики Європейського суду з прав людини на розвиток криміналістики в Україні
Authors: ЧОРНОУС ЮЛІЯ
Published: December 2021

Розвиток правової системи нашої держави спрямований на інтеграцію до світового та європейського співтовариства. Нині криміналістика активно розвивається, залучаючи інноваційні засоби, методи і прийоми до вирішення поставлених завдань. Міжнародні договори, згода на обов’язковість яких надана Верховною Радою України, практика Європейського суду з прав людини (ЄСПЛ) входять до системи кримінального процесуального законодавства Україні і є новим джерелом розвитку науки криміналістики.
Мета статті полягає у висвітленні особливостей впливу інтеграційних процесів розвитку правоохоронної системи держави на предмет науки криміналістики, і безпосередньо – впливу міжнародних договорів та практики ЄСПЛ на розвиток криміналістики в Україні.
За результатами дослідження встановлено, що міжнародні договори та практика ЄСПЛ визначають формування теоретико-методологічних, правових, праксеологічних засад науки криміналістики. Однією із форм виразу такого впливу є розроб лення та практична реалізація криміналістичних засобів, методів і прийомів розслідування кримінальних правопорушень, формування практичного “інструментарію” науки криміналістики з урахуванням міжнародного та європейського досвіду. Тлумачення міжнародних договорів України та практики ЄСПЛ дали змогу виокремити такі напрями впливу вказаних джерел на розвиток науки криміналістики, розроблення та практичну реалізацію криміналістичних засобів, методів і прийо мів: забезпечення захисту прав і свобод людини; розслідування кримінальних правопорушень із врахуванням кращого міжнародного та європейського досвіду; підвищення ефективності реалізації заходів міжнародного співробітництва під час кримінального провадження; забезпечення ефективного розслідування та судового розгляду справ про міжнародні злочини.
Підсумовано, що формування теоретико-методологічного підґрунтя криміналістики з урахуванням положень міжнародних договорів та практики ЄСПЛ є важливим для здійснення таких наукових криміналістичних досліджень, визначає зміст практичної правозастосовної діяльності, створює передумови для розроблення ефективних криміналістичних рекомендацій для практичних працівниківправоохо ронних органів. Дотримання положень міжнародних договорів та практики ЄСПЛ визначає допустимість криміналістичних засобів, методів і прийомів, є джерелом їх розвитку й удосконалення.
Громадянство та вакцинний націоналізм у дії (ревіталізація свободи пересування в Європейському Союзі)
Authors: СОФІНСЬКА ІРИНА
Published: December 2021

Пандемія COVID-19 несподівано змінила світопорядок: від глобального та масштабного обмеження (сегментування) прав і свобод людини до посилення дискримінації, сегрегації, нетерпимості і цензури думок та висловлювань, вакцинного націоналізму. Загальмувавши міграцію та призупинивши свободу пересування осіб, відбулося “зіткнення” захисту універсальних прав людини і національної безпеки, етики, моралі та консюмеризму. Конституційні та світоглядні цінності, народовладдя (демократія), правовладдя (верховенство права) потребують суттєвого переосмислення під впливом поширення COVID-19 у Європі та світі. Вакцинний націоналізм проявляється не лише у масштабному резервуванні вакцини урядом конкретної держави для власних потреб, а й у вибірковості й ексклюзивності її розповсюдження, використання для вакцинації населення (інколи винятково власних громадян, не враховуючи вразливі верстви населення, які є рези дентами цієї держави). Вакцинний націоналізм не передбачає згуртованість і коопе рацію з метою подолання пандемії COVID-19, а навпаки, диверсифікацію із глобального на локальний рівень. Необхідне повне перезавантаження світоглядного ядра конституційних цінностей у контексті тріади взаємовідносин “особа – держава – суспіль ство”. Запровадження сертифіката COVID-19 в Європейському Сою зі (ЄС) покликане ревіталізувати свободу пересування осіб, відновити бізнес та економіку держав – членів ЄС, зменшити безробіття, а також запобігти дискримінації та сегрегеції людей, сегментуванню прав людини. Мета статті – обґрунтувати запровадження сертифіката COVID-19 у ЄС як результат подолання вакцинного націоналізму за допомогою солідарності та кооперації, а також компромісу між органами влади ЄС і національними урядами держав – членів ЄС заради дотримання конституційних цінностей, забезпечення національної безпеки, гарантування прав людини та відновлення свободи пересування осіб. Гарантування універсальних прав людини, громадянство та вакцинна паспортизація (серти фікація), вакцинний націоналізм – це частина спектру тем, які викликають інтерес учених із різних держав світу (серед них варто виокремити К. Бенуа, Є. Джанкіч, Дж. МакБрайда, Л. Пікколі, Д. Рюдін, П. Спіро, С. Рейнзі, Дж. Торпі). В Україні дослідження таких питань є фрагментарними та спорадичними. Актуальності додають нещодавні рішення Європейського суд з прав людини у справі Feilazoo v. Malta (2021) і комунікації з урядами держав у справах Spînu v. Romania (no. 29443/20), Magdić v. Croatia (no. 17578/20) у контексті запровадження компетентними органами держави під час поширення COVID-19 суттєвих обмежень прав людини.
