Niesłyszący adolescenci wobec zjawiska samotności – wiodące determinanty ryzykownych zachowań w sieci
Authors: Michalczyk Anna
Published: January 2022

Okres adolescencji jest szczególnym czasem w życiu młodego człowieka. Staje on wówczas przed wieloma ważnymi wyborami na płaszczyźnie zawodowej i osobistej – podejmuje pierwszą pracę zawodową oraz zaczyna tworzyć trwałe relacje. Sposób radzenia sobie z problematycznymi wyborami życiowymi jest w dużej mierze zdeterminowany prawidłowo ukształtowaną osobowością i adekwatną samooceną, które tworzą się w okresie wczesnego dzieciństwa. Czas ten okazuje się być fundamentalny dla rozwoju i przyszłego życia młodego człowieka. Styl więzi, jaką dziecko tworzy bowiem ze swoim opiekunem, może znacząco wpływać na występowanie w przyszłości pewnych deficytów czy trudności. Braki te będą znacząco wpływać na jakość życia młodego człowieka, zaś próby ich kompensowania mogą się zakończyć na różne sposoby. Samotność emocjonalna i poczucie wyobcowania niejednokrotnie prowadzą do ucieczki w wirtualną rzeczywistość, co niesie za sobą ryzyko zachowań związanych z szeroko rozumianym uzależnieniem, w tym również od internetu. Badaniami objęte zostały dwie grupy adolescentów – słyszących i z uszkodzonym słuchem. Ich wyniki wskazały jednoznacznie na fakt poczucia wyobcowania, izolacji i samotności wśród niesłyszącej grupy respondentów.
How IT Investments Help Hospitals Gain and Sustain Reputation in the Media: The Role of Signaling and Framing
Authors: Salge Torsten Oliver , Antons David , Barrett Michael , Kohli Rajiv , Oborn Eivor , Polykarpou Stavros
Published: January 2022

Practice- and Policy-Oriented Abstract

Understanding how IT investments help organizations to build and sustain reputation is of particular relevance for healthcare practitioners and policy makers because patients are often unable to assess the quality of care, relying instead on the reputation of health service providers in the media, such as newspapers. As information intermediaries, journalists detect, aggregate, and translate the weaker signals for quality, such as state-of-the-art IT, that a hospital emanates. Our analysis of 152 hospital organizations in England, complemented by interviews with healthcare journalists, shows that journalists write less negatively about hospitals when healthcare organizations’ IT equipment investments are high. This implies that investments in IT equipment can buffer hospitals from negative press, thereby helping them to gain and maintain a strong reputation in the media. Practitioners and policy makers may incorporate the reputational effect of IT when making investment decisions and further amplify such IT investment through press releases, corporate reports, and media interactions.

Published: January 2022

A cross sectional study on infectious bursal disease was conducted in apparently healthy backyard chicken at Waliso district of Southwestern Shoa, central oromia, Ethiopia from from November, 2018 to October, 2019. A total of 282 chickens were randomly selected to estimate seroprevalence of IBD infection and to identify the likely potential risk factors for the disease. Serum samples collected and serological test conducted in laboratory at National Animal Health Diagnosis and Investigation Center Sebeta, Ethopia. Out of 282 serum samples tested 224 were positive for indirect ELISA technique and the overall seroprevalence of IBDV in the study area was found to be 79.43% at individual level. Educational level of owners, kebeles and flock size significantly affect seroprevalence of IBD in the study area. The effect of difference in managements like source of replacement, frequency of house cleaning, use of disinfectant and isolation practice has a significant effect on IBDV sero-prevalence. A lower seroprevalence of IBDV was reported in good hygienic level of house (26.7%) than poor level of chicken house hygiene (96.4%) with statistically significant difference (P < 0.05). The seroprevalence of IBDV in the present study associated with chicken management, flock size, owner education level and other animal related risk factors for occurrence of the disease. Therefore, awareness on chicken health management, and importance of immunization would help to minimize the prevalence of the disease and play crucial role in the control of the disease. Furthermore, characterizing virus strains circulating in the area in future study is recommended.
Global Public Policy studies
Authors: Porto de Oliveira Osmany
Published: January 2022

Globalisation has helped to intensify the international flow of people, information and policies. Following this process there has been increasing global concern regarding problems in areas such as immigration, health, poverty, among others. Various agents are transnationally engaged in common responses to these issues. The classic definition of public policies is related to actions undertaken by governments to solve the problems within their jurisdictions. However, often problems do not respect national boundaries. Sometimes, policies need to involve other nations. This article discusses the main issues, concepts and challenges in the study of global public policies.

First, the article presents a review of the existing literature. Second, it introduces the key agents and agendas of global public policy. The discussion section focuses on the latest challenges and opportunities for research in Global Public Policy studies. Finally, new avenues of research are introduced, such as the dimension of power, the impact of the far-right and the outbreak of the COVID-19 pandemic.

Raman scattering in the incident narrow-linewidth fiber amplifier is
verified to be the dominant factor that induces thermal blooming in
the beam combining system. When the power density of
Raman light reaches only

content in the atmosphere has a
positive relationship with the thermal blooming effect and study the
influence of the humidity on the thermal blooming effect. The
influence of the optical path length on the thermal blooming effect is
also revealed. The result shows that the focusing property of the
far-field beam degrades gradually as the optical path length increases
from 100 to 450 mm. The results are conducive to optimize the beam
quality of spectral beam combining.
High-performance heterogeneous FPGA data-flow architecture for Fourier ptychographic microscopy
Authors: Zhao Hongyang , Hui Wangwei , Ye Qing , Huang Kaicheng , Shi Qiushuai , Tian Jianguo , Zhou Wenyuan
Published: January 2022

Fourier ptychographic microscopy (FPM) is a recently developed computational imaging technique that can achieve both high-resolution and a wide field-of-view via a sequence of low-resolution images. FPM is a complex iterative process, and it is difficult to meet the needs of rapid reconstruction imaging with the conventional FPM deployed on general purpose processors. In this paper, we propose a high-performance heterogeneous field-programmable gate array (FPGA) architecture based on the principle of full pipeline and the data-flow structure for the iterative reconstruction procedure of FPM. By optimizing the architecture network at gate-level logic circuits, the running time of the FPGA-based FPM reconstruction procedure is nearly 20 times faster than conventional methods. Our proposed architecture can be used to develop FPM imaging equipment that meets resource and performance requirements.
El fashion film como acción de la marca. El caso de Europa II en Vogue
Authors: Hernández-Herrera María , Gil-Ruiz Francisco-José , García-Guardia María-Luisa , Ayestarán-Crespo Raquel
Published: January 2022

Este trabajo estudia el fashion film como herramienta de marketing a través del estudio del cortometraje Europa II de Vogue. En primer lugar, la investigación profundiza en la moda, en la marca Vogue, en la propia naturaleza del fashion film como formato publicitario, y en la importancia de las asociaciones de marca. En segundo lugar, se lleva a cabo un estudio exploratorio que identifica las asociaciones de la marca Vogue presentes en Europa II. La metodología empleada parte de un análisis semiótico centrado en extraer aquellas asociaciones (referencias y valores culturales latentes en él) desde la propuesta narrativa de Europa II, identificando así los significados presentes en su narrativa, aquellos que en definitiva hablan de la marca, de cómo quiere ser percibida. Hecho esto, se contrastaron las asociaciones resultantes mediante una entrevista a siete expertos en el ámbito del marketing y/o la comunicación. De entre las principales conclusiones, cabe destacar que Europa II sirve a Vogue para rejuvenecer su target y, por ende, conectar con nuevos públicos. Las asociaciones de marca aportan de este modo un punto de inflexión en cuanto al poder persuasivo de Europa II, conectando el análisis narrativo con el significado de la marca.
El proceso de cocreación de marca a través del eWOM: perfil, actitud y comportamiento de los usuarios
Authors: Carcelén-García Sonia , Diaz-Soloaga Paloma
Published: January 2022

El concepto de cocreación de marca ha sido ampliamente tratado en trabajos académicos durante los últimos 15 años y, aunque todavía no se ha alcanzado un consenso en su definición y alcance, los expertos reconocen la eficacia de esta actividad que relaciona de forma directa las marcas con los distintos stakeholders, en particular con los clientes. Se han realizado importantes aportaciones en la descripción de este fenómeno, y en las motivaciones y perfiles de la cocreación entre los distintos públicos, así como en los beneficios y riesgos de esta práctica. El presente estudio, realizado a través de una encuesta online a una muestra de 1.521 consumidores españoles en noviembre de 2020, profundiza en las actitudes, opiniones y comportamientos hacia la cocreación de marca y descubre que, más allá de otros factores, las variables sociodemográficas siguen siendo determinantes a la hora de desarrollar eWOM, la actividad principal del proceso de cocreación. Las conclusiones permiten identificar aquellos perfiles más dispuestos a recomendar y crear contenidos de marca.

Authors: García-Jiménez Antonio , Suárez-Álvarez Rebeca , Montes-Vozmediano Manuel
Published: January 2022

YouTube es la red social más vista por los menores en la que crean y difunden sus producciones audiovisuales con los riesgos que comporta y a los que se ven expuestos. El objetivo de esta investigación es precisar las situaciones de vulnerabilidad de los vídeos de los y las adolescentes españoles en YouTube, a tenor de su género y edad. Mediante un análisis de contenido de 300 vídeos subidos por youtubers adolescentes españoles de entre 11 y 17 años se estudia la incorporación de comentarios reprobables, vocabulario obsceno, falta de protección de la identidad y presencia de imágenes inapropiadas desde el anuncio del estado de alarma hasta su finalización, a causa de la COVID-19. Los resultados confirman las diferencias de género en relación a las situaciones de vulnerabilidad en esta red social. Las chicas están mucho más expuestas en los vídeos que publican (85% registra protección baja) que los chicos (81% registra protección alta). Los chicos de 16 y 17 años son los que más comentarios obscenos y reprobables utilizan, y chicos y chicas prácticamente no difunden imágenes censurables.
Menores y contenidos digitales. Derechos y obligaciones
Authors: Serrano-Maillo Isabel
Published: January 2022

Cuando hablamos de niños y mensaje publicitario, nos enfrentamos a tres realidades muy distintas: el niño frente al mensaje, el niño como actor publicitario y el niño como creador de contenidos publicitarios. En este artículo abordamos estas tres situaciones desde la perspectiva de los derechos y obligaciones de los menores. Partimos del acercamiento a conceptos básicos como la definición de niño, madurez suficiente, el mejor interés del menor, principios publicitarios, limitaciones a la publicidad por sector, edad o producto. Posteriormente, tratamos de dar respuesta a preguntas como como: ¿Qué se puede y qué no se puede hacer en la publicidad dirigida a los niños? ¿Qué derechos y obligaciones tienen los niños en el entorno publicitario? ¿Vale todo para un influencer? Preguntas que requieren respuesta. En este trabajo se hace referencia a todas las normas que regulan estos temas en nuestro país. Normas jurídicas y de autorregulación que conviven con normas europeas, autonómicas, sectoriales…. Como conclusión principal: hay demasiadas normas para regular una única realidad, lo que dificulta distinguir las conductas lícitas de las ilícitas, sobre todo en el campo de la infancia. Sería deseable -y necesaria- una legislación clara y unívoca que regulara todos los aspectos referidos a la infancia y la publicidad.

Authors: Sánchez-Amboage Eva , Toural-Bran Carlos , Membiela-Pollán Matías , Crespo-Pereira Verónica
Published: January 2022

En una sociedad marcada por la cuestión digital y la pandemia mundial por COVID-19, los museos han experimentado la necesidad de incorporarse a nuevas plataformas sociales, donde se encuentran los públicos más jóvenes. Este contexto ha propiciado una intensificación del uso de estos canales así como una reconfiguración de las estrategias comunicativas en el entorno digital por parte de los museos. El objetivo de esta investigación es analizar cómo el Museo Nacional del Prado usa la plataforma TikTok dentro de su estrategia de marca y estudiar su producción de short video content, formato característico de esta red social. Para ello, se aborda un estudio de caso en el que se desarrollan una entrevista estructurada con personal del área de comunicación y redes sociales del museo así como un análisis de contenido para el que se elabora una ficha ad hoc. Los resultados muestran que la estructura narrativa y el lenguaje utilizado se adecúan siempre al público y a la plataforma desde el rigor y el respeto, usando un registro informal con el objetivo de transmitir conocimiento sin dejar de conectar de forma más eficiente con el patrón de consumo de la red social.

A Motion Estimation based Algorithm for Encoding Time Reduction in HEVC
Authors: Sairam S. Karthik , Muralidhar P.
Published: January 2022

High Efficiency Video Coding (HEVC) is a video compression standard that offers 50% more efficiency at the expense of high encoding time contrasted with the H.264 Advanced Video Coding (AVC) standard. The encoding time must be reduced to satisfy the needs of real-time applications. This paper has proposed the Multi- Level Resolution Vertical Subsampling (MLRVS) algorithm to reduce the encoding time. The vertical subsampling minimizes the number of Sum of Absolute Difference (SAD) computations during the motion estimation process. The complexity reduction algorithm is also used for fast coding the coefficients of the quantised block using a flag decision. Two distinct search patterns are suggested: New Cross Diamond Diamond (NCDD) and New Cross Diamond Hexagonal (NCDH) search patterns, which reduce the time needed to locate the motion vectors. In this paper, the MLRVS algorithm with NCDD and MLRVS algorithm with NCDH search patterns are simulated separately and analyzed. The results show that the encoding time of the encoder is decreased by 55% with MLRVS algorithm using NCDD search pattern and 56% with MLRVS using NCDH search pattern compared to HM16.5 with Test Zone (TZ) search algorithm. These results are achieved with a slight increase in bit rate and negligible deterioration in output video quality.
High Speed Machining for Enhancing the AZ91 Magnesium Alloy Surface Characteristics Influence and Optimisation of Machining Parameters
Authors: Marakini Vikas , Pai Srinivasa P , Bhat Uday K , Singh Dinesh Thakur , Achar Bhaskar P
Published: January 2022

In this study, optimum machining parameters are evaluated for enhancing the surface roughness and hardness of AZ91 alloy using Taguchi design of experiments with Grey Relational Analysis. Dry face milling is performed using cutting conditions determined using Taguchi L9 design and Grey Relational Analysis has been used for the optimization of multiple objectives. Taguchi’s signal-to-noise ratio analysis is also performed individually for both characteristics and grey relational grade to identify the most influential machining parameter affecting them. Further, Analysis of Variance is carried to see the contribution of factors on both surface roughness and hardness. Finally, the predicted trends obtained from the signal-to-noise ratio are validated using confirmation experiments. The study showed the effectiveness of Taguchi design combined with Grey Relational Analysis for the multi-objective problems such as surface characteristics studies.
Modelling and Optimisation of UHF band EW Based WTA Problem within the Scope of Threat Assessment
Authors: Acarlar Barlas Merve , Gozde Haluk , Ozden Semih
Published: January 2022

The classical weapon target allocation (WTA) problem has been evaluated within the scope of electronic warfare (EW) threat assessment with an electromagnetic effect-based jammer- tactical radio engagement approach. As different from the literature, optimum allocation of non-directional jammers operating at different operating UHF frequencies under constraints to RF emitters is aimed in this study. The values of the targets are modelled using an original threat assessment algorithm developed that takes into account operating frequencies, jamming distance, and weather conditions. The computed jammer-target effect matrix has been solved under different scenarios according to the efficiency and cost constraints. It is seen at the end of the simulations that the allocation results for EW applications largely depend on the effect ratio used. The better results are taken in the case of under 0.5 effect ratio. Finally, jammer-radio allocation problem specified at the suggested model is solved successfully and effectively.
Generic Methodology for Formal Verification of UML Models
Authors: Kochaleema K.H. , Kumar G. Santhosh
Published: January 2022

This paper discusses a Unified Modelling Language (UML) based formal verification methodology for early error detection in the model-based software development cycle. Our approach proposes a UML-based formal verification process utilising functional and behavioural modelling artifacts of UML. It reinforces these artifacts with formal model transition and property verification. The main contribution is a UML to Labelled Transition System (LTS) Translator application that automatically converts UML Statecharts to formal models. Property specifications are derived from system requirements and corresponding Computational Tree Logic (CTL)/Linear Temporal Logic (LTL) model checking procedure verifies property entailment in LTS. With its ability to verify CTL and LTL specifications, the methodology becomes generic for verifying all types of embedded system behaviours. The steep learning curve associated with formal methods is avoided through the automatic formal model generation and thus reduces the reluctance of using formal methods in software development projects. A case study of an embedded controller used in military applications validates the methodology. It establishes how the methodology finds its use in verifying the correctness and consistency of UML models before implementation.
«Система социологии» Питирима Сорокина и системно-коммуникативный подход
Authors: Антоновский Александр Юрьевич , Бараш Раиса Эдуардовна
Published: January 2022

В статье реконструируется ряд идей русско-американского социолога и философа Питирима Сорокина, сформулированных в российский период его творчества. Авторы анализируют программу автономизации социологии как трансдисциплинарной науки и показывают, что Сорокину удалось сформулировать фундаментальные положения системно-коммуникативного подхода в социальной теории, зафиксировать важнейшие предпосылки кристаллизации современного коммуникативно дифференцированного общества. Используя достижения современного ему естествознания, психологии, философии, лингвистики, эволюционной теории, Сорокин описал позитивную программу системно-коммуникативного подхода к исследованию общества, которая фактически реализовалась и тем самым верифицировалась лишь десятилетия спустя в рамках коммуникативной теории Никласа Лумана. Эта программа включала в себя анализ «минимального проявления» общества, которое получило название «взаимодействие». Это понятие мы отожествляем с современным понятием «коммуникации».

(Не)доступная городская среда: реакции пользователей YouTube на условия передвижения людей с инвалидностью
Authors: Коржук Софья Владимировна
Published: January 2022

Статья посвящена рассмотрению условий для передвижения людей с инвалидностью в городской среде как социальной проблемы. Использован конструкционистский подход к социальным проблемам, в рамках которого социальные проблемы рассматриваются не как объективные дисфункциональные условия, а как деятельность индивидов или групп, обосновывающих проблематичный статус условий и требующих их исправления. В фокусе исследования — реакции пользователей YouTube на вопросы доступности городского пространства для людей с инвалидностью, выражаемые посредством комментариев к выпускам YouTube-программы «На колесах». Осуществлен качественно-количественный анализ 7 472 сообщений зрителей. Подавляющее большинство зрителей идентифицировали доступность городской среды как социальную проблему, демонстрировали яркие эмоциональные реакции на условия передвижения людей с инвалидностью. Доминирующие риторические стратегии обоснования проблематичности условия в комментариях — риторика бедствия, риторика опасности и риторика наделения правом, согласно методологии П. Ибарры и Дж. Китсьюза. В рамках риторики наделения правом подчеркивается значимость формирования доступной среды для всех людей, включая людей с инвалидностью, отсутствие доступной среды определяется как форма дискриминации маломобильных граждан. Риторика бедствия связывает проблемы доступности с качествами государственной власти России. Риторика опасности рассматривает физические барьеры к передвижению в качестве угрозы здоровью и безопасности людей. При этом пользователи дополняют список тех, кому нужна доступная среда и для кого несовершенства физической среды могут нести опасность. В этот список зрители включают в первую очередь маломобильных граждан, затем велосипедистов, людей, использующих самокаты и т.д., людей с чемоданами или иным грузом, а в итоге приходят к выводу, что доступная среда нужна всем жителям города. Стратегий депроблематизации условия в изучаемых записях меньшинство, в большей их части проблема доступной среды признается, но ставится под сомнение реализуемость идеи «доступной среды для всех».

Is Network Structure Important for Protest Mobilization? Findings from Agent-Based Modeling
Authors: Petrov Alexander P. Ch. , Akhremenko Andrei S. , Zheglov Sergey A. , Kruchinskaia Ekaterina V.
Published: January 2022

In recent decades, the focus of civic engagement research has shifted towards studying social environments’ effects on individuals’ decisions on whether to participate in a given activity or not. Online communication has been increasingly influencing the scale of social environments as well as the features of both online and offline interpersonal communications. Surely, then, individuals’ decisions concerning protest mobilization are bound to be affected by network properties. Using a series of ABM models with different network structures, we try to identify the structural factors of networks that can influence individuals who are deciding whether to join a protest. The established research in this field traditionally points to two structural factors: network topology and homophily. To our knowledge, however, the literature has not considered two above-mentioned structural factors in combination. In other words, their joint influence on protest mobilization has not been tested. To fill this research gap, we combine several network topologies with enabled/disabled homophily and examine how the combination influences protest turnout and survival. Numerical experiments show that homophily is positively associated with the survival of the protest, but negatively with its size for any network topology. Since we infer this conclusion from a theory-based computational model, we also propose how empirical testing can be conducted.

Hodnocení vzdělávacího přínosu škol pomocí přidané hodnoty: srovnání čtyř evropských zemí
Authors: Potužníková Eva
Published: January 2022

Cílem práce je na základě porovnání situace ve čtyřech evropských vzdělávacích systémech (Anglie, Francie, Norsko, Polsko) poukázat na možnosti, ale i rizika spojená s evaluací škol na základě přidané hodnoty.
Metody. Přístupy jednotlivých zemí jsou porovnány podle předem určeného souboru kritérií. Zdrojem dat je technická dokumentace o modelech přidané hodnoty, webové portály pro zveřejňování výsledků a texty o vývoji modelů a využívání dat o přidané hodnotě.
Výsledky. Preferovaným zdrojem dat pro výpočet přidané hodnoty jsou standardizované testy či zkoušky. Dostupnost dat ovlivňuje volbu vzdělávacího stupně, hodnocených vzdělávacích oblastí (předmětů) i zařazení kontextových proměnných. Při zveřejňování přidané hodnoty země brání otevřenému srovnávání škol, netvoří žebříčky a přiznávají statistickou nejistotu spojenou s měřením. Informace o přidané hodnotě slouží jako zpětná vazba školám.
Závěry. Indikátory přidané hodnoty jsou spravedlivým ukazatelem vzdělávacího přínosu škol, s jejich zaváděním jsou však spojena rizika jako vynechání důležitých proměnných kvůli nedostupnosti dat, nedostatek odborných kapacit pro implementaci a rozvoj metody a malá využitelnost pro zlepšování kvality vzdělávání.
Intervence české vzdělávací politiky ve vztahu k výzkumně doloženým poznatkům a doporučením: případ požadavků na kvalifikaci učitele
Authors: Spilková Vladimíra , Reimannová Irena
Published: January 2022

Cílem studie je analýza přístupu české vzdělávací politiky ke kvalifikačním požadavkům na vstup do učitelské profese v souvislosti s aktuálně projednávanou novelou zákona č. 563/2004 Sb., o pedagogických pracovnících, a zejména jejím kontroverzním § 9a odst. 1, který otevírá učitelskou profesi vysokoškolsky vzdělaným odborníkům bez pedagogické kvalifikace. Na případu legislativního procesu v daném tématu je dokumentován a analyzován přístup české vzdělávací politiky k profesi učitele v kontextu vztahů vrcholné decizní sféry k výzkumným zjištěním, mezinárodním trendům a strategiím relevantním pro kvalitu učitelů v 21. století.
Zkoumání uvedeného případu vzdělávací politiky je založeno na metodologii desk research. Klíčové zdroje dat představují dokumenty: legislativní (různé verze novely – sněmovní a senátní tisk novely, pozměňovací návrhy, stenozápisy z jednání obou komor Parlamentu ČR), dokumenty odborné a strategické (na národní i evropské úrovni), MŠMT, stanoviska důležitých aktérů a tiskové zprávy (profesní asociace, odborníci, neziskové organizace, příspěvky na sociálních sítích), mailová komunikace jedné z autorek příspěvku s poslanci a senátory.
V diskusi výsledků jsou kriticky reflektovány obsah a způsob zdůvodňování devalvace kvalifikačních požadavků na učitele ze strany politiků. Je zhodnocena relevance a korektnost hlavních důvodů prezentovaných předkladatelem novely – MŠMT a dalšími klíčovými aktéry legislativního procesu. Dále míra využití relevantních výzkumných dat a doporučení v procesu tvorby návrhu a politického rozhodování v otázce zákonných požadavků na kvalifikaci učitele.

Traditionally, Viola serpens has been used in the treatment of several human disorders including liver diseases without any scientific evidence. As the current therapies are not very effective and face challenges of unwanted effects and patient compliance, therefore more effective and safe agents are highly needed. The current study aimed to evaluate the hepatoprotective potential of the crude extract and subsequent fractions of the whole plant in the in-vivo model using various hematological and histopathological parameters followed by an HPLC study for the identification of phenolic compounds. Rabbits (1000-1200 g) were used in the study. Paracetamol (2g) was used to induce hepatotoxicity in experimental rabbits. The plant extract was used in two doses (150 and 300 mg/kg body weights) for eight days. The hematological parameters AST, ALT and ALP values were determined along with the histopathology of the liver. Phenolic compounds were identified by high-performance liquid chromatography (HPLC) Agilent-1260 infinity from their retention time, UV spectra and available standards while quantification was done taking the percent peak area. The doses 150 and 300 mg/kg body weight seemed to be more effective. The hematological values and the histopathological slides show the hepatoprotective effect of the plant. Regeneration indicated the presence of nuclei, nuclear cleaning, prominent nucleoli, RBC’s, central veins and plates of hepatocytes. The HPLC studies revealed the presence of a number of phenicol compounds. The crude extract and the subsequent fractions of the plant possess strong hepatoprotective activity, providing a scientific rationale for its uses in the treatment of liver toxicities.

Authors: Nykonenko A. O. , Havrylenko B. S.
Published: January 2022

Pelvic congestion syndrome is a relatively recent, but actual and separate nosological form. Pelvic varicocele is a form of varicose disease, which is increasingly regarded as the main cause of chronic pelvic pain in women with various clinical manifestations. A woman with chronic pelvic pain is a difficult patient with combative behavior, who contacts with physicians in various specialties. There are many causes of chronic pelvic pain, but pelvic congestion syndrome has a special place. In recent years, in addition to widespread use of diagnostic radiology, the relevance of this pathology is beyond any doubt.
The aim of the study was to summarize and present literature data on the etiology, pathogenesis, clinical manifestations, diagnosis and treatment of pelvic congestion syndrome by analyzing the literature data.
Materials and methods. A non-systematic review was conducted using PubMed, Web of Science, Google and Google Scholar databases. The review included free full-text articles published between 1974 and 2021 using key words: pelvic congestion syndrome, pelvic varices, pelvic venous disorders, pelvic varicocele, pelvic venous stasis, chronic pelvic pain, gonadal veins, ovarian veins, vena ovarica, Nutcracker syndrome, May–Thurner syndrome.
Conclusions. Pelvic congestion syndrome is still a rarely diagnosed pathology in patients with chronic pelvic pain. Detailed medical history, physical examination as well as maintaining diagnostic algorithm would allow the disease to be diagnosed correctly and timely. The choice of method for surgical intervention is a key point in the treatment of patients with pelvic congestion syndrome, but today there are no criteria for the choice of one, so the problem is far from being resolved and requires further study and research.

Today, the important problem is the creation of new decamethoxine and thiotriazoline based drugs for the treatment of stomatitis.
The aim of the work is to develop a method for quantitative determination of decamethoxine and thiotriazoline in the model mixture (1:25) by spectrophotometry.
Materials and methods. Series 6 model mixtures were made at the ratio of decamethoxine and thiotriazoline 1:25. We used certified substances: thiotriazoline series GTT 3460911 (manufacturer: State Enterprise Chemical Reagents Plant, Kharkiv), decamethoxine series № 010915 (manufacturer: LLC “PHARMCHIM”). Optizen POP spectrophotometer, polyvinyl alcohol, hydrochloric acid, and eosin were used.
Results. A method for quantitative determination of decamethoxine and thiotriazoline in MS was developed. It was established that the content of active substances in MS is thiotriazoline from 0.5021 to 0.5096, decamethoxine from 0.0207 to 0.0211.
Conclusions. A method for quantitative determination of decamethoxine and thiotriazoline in MS has been developed. The method of quantitative determination of decamethoxine and thiotriazoline in MS is reproducible.

Authors: Kuzmina H. P. , Lazarenko O. M.
Published: January 2022

The aim. To analyze the frequency of atherosclerotic lesions of the carotid arteries and association with the lipid metabolism and inflammatory markers in hypertensive patients with gout.
Materials and methods. 122 patients with hypertension aged 30 to 65 years were examined (mean age (56.0 (47.0; 62.0)), inclu­ding 104 men (85.2 %) and 18 women (14.8 %). Group 1 included 72 hypertensive patients with gout; group 2 – 50 hypertensive patients without gout; group 3 – 20 gout patients without hypertension. Serum levels of high sensitivity C-reactive protein were detected by enzyme-linked immunosorbent assay. Serum ferritin levels were measured using electrochemiluminescent detection. The patients underwent carotid artery ultrasound according to standard methods.
Results. The duration of gout exacerbation and the pain intensity evaluated with the visual analog scale (VAS) (P < 0.01) were significantly higher in group 1, than those in group 3 (P < 0.01). Serum ferritin levels were 2.6 (P < 0.01) times higher in group 1 than those in group 2. In patients with gout, the levels of ferritin were significantly 2.1 times higher, than in group 2 (P < 0.01). The levels of hsСRP in patients of group 1 were 3.1 times higher than those in group 2 (P < 0.01). The proportion of patients with intima-media complex (IMC) thickness ≥0.9 mm was higher in group 1 than in groups 2 (χ2 = 4.58, P < 0.05) and 3 (χ2 = 24.96, P < 0.01). In the structure of plaques, isoechoic were significantly more often seen among group 1 patients as compared to group 3 (χ2 = 6.56, P < 0.01), and hyperechoic – as compared to group 2 (χ2 = 4.63, P < 0.05). Hypoechoic plaques were detected in groups 1 and 2 with similar frequency (P > 0.05). This type of plaque was associated with a high risk of cerebrovascular events. In the patients with arterial hypertension and gout, a significant moderate positive correlation was found between the IMC thickness and the serum uric acid level (rs = 0.46, P < 0.01), hsCRP (rs = 0.33, P < 0.01), age (rs = 0.33; P < 0.01), duration of gout (rs = 0.27, P < 0.05) and VAS (rs = 0.39, P < 0.01); the level of hsCRP was correlated with the presence of atherosclerotic plaques (τ = +0.64, P < 0.05).
Conclusions. The combination of hypertension with gout in patients was associated with a high incidence of IMC thickness ≥0.9 mm and atherosclerotic plaques, more severe disorders of purine and lipid metabolism, increased inflammatory markers (ferritin and hsCRP), that should be considered not only in the aspect of chronic inflammation, but also as a part of the disease.

Published: January 2022

The aim is to evaluate the effect of metabolic activity of intestinal microflora on laboratory manifestations of carbohydrate malabsorption syndrome in early-aged children with rotavirus infection by studying the main intestinal metabolites – short-chain fatty acids in faeces.
Materials and methods. 60 breastfed children with rotavirus infection aged 1–24 months were examined. The total amount of carbohydrates in faecal samples was determined using Benedict’s test, and the detection of short-chain fatty acids in faeces was carried out using liquid chromatography in the dynamics of the disease – on the 3rd, 5th and 10th day.
Results. It was established, that the amount of reducing sugars in faeces decreased with the increasing concentration of intestinal microflora metabolites during the entire period of rotavirus infection. In patients with ≤0.5 % level of carbohydrates in faeces, the total content of short-chain fatty acids was the highest and exceeded by 2.0, 1.8 and 1.7 times the indicators of children with Benedict’s test values >0.5 % on the 3rd, 5th and 10th days of the disease, respectively (p < 0.05). A decrease in the metabolic activity of the intestinal microbiota in the above category of children occurred mainly due to a deficiency in the production of acetic and propionic acids (P < 0.05). In the acute period of the disease, an imbalance in the intestinal microbiota infrastructure was noted towards a deficiency of obligate anaerobes that was expressed in a decrease in the anaerobic index (P < 0.05). The severity of these disorders influenced the severity of carbohydrate malabsorption: with an increase in the level of undigested sugars in faeces >0.5 %, the anaerobic index values were 3 and 5 times lower than at a carbohydrate level ≤0.5 % on the 3rd and 5th days of the disease, respectively (P < 0.05).
Conclusions. It has been found that early-aged children with rotavirus infection have structural and functional disorders of the intestinal microflora, which influence the severity of carbohydrate malabsorption syndrome. The lower the saccharolytic activity of intestinal bacteria, the more pronounced the manifestations of this syndrome during the entire period of the disease.
Use of tocilizumab in the combination treatment of a COVID-19 patient with concomitant rheumatoid arthritis (a case report)
Authors: Vizir V. A. , Sadomov A. S. , Demidenko O. V.
Published: January 2022

The aim is to familiarize practitioners with the clinical case of tocilizumab use in the combination treatment of the coronavirus disease (COVID-19) patient with concomitant rheumatoid arthritis.
Materials and methods. The clinical case shows our own follow-up of COVID-19 clinical course in the patient with concomitant rheumatoid arthritis during combination treatment with the use of a recombinant humanized anti-interleukin-6 receptor monoclonal antibody tocilizumab.
Results. The patient with a severe COVID-19 course, whose examination and treatment results are given in the article, was comorbid for rheumatoid arthritis. The cytokine storm development at the hospital stage was confirmed by an increase in markers of systemic inflammation: C-reactive protein, D-dimer, fibrinogen, an almost 50-fold increase in serum interleukin-6 level, as well as absolute and relative lymphocytopenia. Despite the anti-inflammatory therapy administered with systemic corticosteroids, the patient’s condition progressively worsened. After assessing the indications and contraindications, it was decided to use the interleukin-6 receptor inhibitor tocilizumab, followed by rapid clinical, laboratory and X-ray positive response to the treatment. The understanding of tocilizumab use in patients with COVID-19 at the current stage was formed based on the comparative analysis of our own clinical case data and the results of relevant clinical trials, world recommendations and guidelines.
Conclusions. The use of recombinant humanized anti-interleukin-6 receptor monoclonal antibody tocilizumab in the combination treatment of severe COVID-19 with concomitant rheumatoid arthritis is pathogenetically based and decreases the main clinical and laboratory signs of cytokine storm, respiratory failure, improves chest x-ray findings and reduces the length of hospital stay. Further large randomized placebo-controlled trials including the population of patients with various comorbid conditions are needed to clarify conclusively the place and role of anti-cytokine drugs in the treatment of COVID-19 patients.
