Reconstructive valve-sparing procedures on the aortic valve are one of the most dynamically developing directions in the cardiac surgery. Today cardiac surgeons all over the world prefer the aortic valve sparingoperation using autologous tissues instead biological and mechanical prosthetics. The Ross, Yakub, David, Ozaki procedures have proved their effectives, and their indicators of long-term freedom from reoperations are not inferior to classical prosthetics. In this review the authors describe the key points of the native aortic valve reconstruction. Especially, from the surgical point of view the issues of anatomy of the aortic root and the determination of the optimal «patients» for the valve-sparing procedure are discussed. The principles of reconstruction of various variants of valve development, such as uni-, bi-, three-, and quadricuspid valve anatomy, are presented in details. The approaches to aortic valve repair are described step by step, including a description of the aortic root exposure technique, options for correcting prolapse, eliminating fenestration, and annuloplasty. The evaluation of literature data showed that the overall risks of aortic valve repair in isolation or as a component of a combined intervention are nothigher than in patients with biological or mechanical prosthetics. The violation of the orientation of the commissures, the use of a pericardialcatheter, long-term prolapse, as well as expansion of the annulus fibrous are considred as an independent risk factors of significant regurgitation and reoperations in the long term after reconstruction.

Atherosclerosis of lower-extremity arterial disease is a common pathology in diabetes mellitus, contributing to the development of ischemic and neuroischemic forms of diabetic foot syndrome. Early diagnosis of vascular lesions helps to reduce the number of cardiovascular complications, performed amputations and improves the quality of life in these patients.The review presents the current arsenal of modern comprehensive examinations of patients with diabetic foot syndrome, including clinical and functional screening, non-invasive and invasive methods of radiological diagnosis, as well as specific assessment scales and new classifications that allow detailing and systematizing trophic foot changes with the ability to predict the course of the pathological processoccurring at sites. The using of open revascularization methods helps to achieve the healing of diabetic ulcers in a large percentage of cases, but the point is the problems associated with the localization of the lesion, the choice of conduit for bypass surgery and technical aspects significantly limit the possibilities of this treatment method. Recent technological advances in the development of endovascular surgery have expanded the indications for successful revascularization. The article highlights the results of shunting and endovascular methods in the treatment of atherosclerotic process in infrainguinal area in patients with diabetic foot syndrome.
Heat Flow Modeling for Controlled Focusing of Microwave Hyperthermia of Breast Cancer: a Computational Feasibility Study
Authors: Rajput Jaswantsing L. , Nandgaonkar Anil B. , Nalbalwar Sanjay L. , Wagh Abhay E.
Published: August 2021

Heating the tumor tissue with an optimized amount of microwave energy is a promising combinational therapy, called hyperthermia treatment (HT), used with chemotherapy and radiotherapy. This combinational therapy has shown improvement in the survivorship for patients, and life after treatment. In clinical practice, radiation oncologists are still not using HT as a standard therapy because of some side effects like toxicity and hotspots on the surrounding site. To address this issue, optimal focusing of microwave on tumors, with minimal damage of surrounding tissues, is essential to avoid the side effects of HT. Our article briefly discusses on optimal focusing of microwaves on a tumor, computational feasibility study, and analysis of hyperthermia treatment. For the achievement of best outcomes, electrostatic modeling and heat flow modeling of 2D female breast models with tumors have been carried out. The finite element method (FEM) is used to solve the bio-heat equation at the tumor domain, consisting of radiation and convection-based boundary conditions. Obtained simulation results show that the highest focusing of radiation power on and around the tumor inside the breast has been given higher efficiency for hyperthermia. Our 2D modeling simulation results are helpful for improving hyperthermia treatment of breast cancer patients, with minimal damage to cells in the surrounding. Also, the article includes a mathematical analysis of hyperthermia and FEM modeling results concerning temperature distribution, heat flow, electric field intensity, electric flux density, heat flux density, and temperature variations in the breast tumor.

El objetivo de este trabajo es conocer cómo el estudiante de Diseño se adaptó a las clases virtuales y cuál fue su percepción de su aprendizaje a partir de la nueva realidad producto del COVID-19. Más de la mitad de los estudiantes consideran que desde una perspectiva integral, las clases en línea no permiten alcanzar un aprendizaje como en el espacio presencial, donde se identifica la heterogeneidad de las asignaturas y enseñanza propia del área de diseño. Se sugiere implementar métodos innovadores que permitan mejorar el aprendizaje y la experiencia tanto de los estudiantes como de los docentes en el actual método educativo virtual.
El sobreviviente en documentales sobre juicios por violación a los derechos humanos en Argentina. Una aproximación a la construcción identitaria
Authors: Nicola Mariné
Published: August 2021

El objetivo de este trabajo es hacer un recorrido sobre la imagen del “sobreviviente” que se construye en films documentales que representan los juicios por violación a los derechos humanos durante la última dictadura cívico-militar en Argentina. Desde mediados de la década del ´80 hasta nuestros días podemos constatar desplazamientos en la imagen que se representa en los audiovisuales en torno al sobreviviente. Esto se vincula con procesos colectivos de identificación, donde el “otro” funciona como marco referencial permitiendo a los sujetos legitimarse en la misma oposición, a partir de la diferenciación. En un primer momento, los sobrevivientes tienen nombre pero no rostro, en el Juicio a las Juntas de Comandantes (1985) son testigos de espaldas a la cámara, con una adscripción identitaria asociada a la identidad personal que los muestra como víctima de diferentes torturas y vejámenes, y desprovistos de intereses, compromisos y luchas. Con el transcurso del tiempo se restituye a los detenidos desaparecidos la filiación política, y se los aborda como sujetos enmarcados en luchas ideológicas e interacciones sociales, de esta forma se complejiza la identidad del sujeto, y se lo aborda como un actor social contextualizado. El corpus de audiovisuales documentales que representan los juicios por violación a los derechos humanos durante la última dictadura cívico-militar en Argentina está constituido por: “Señores, ¡de pie!” (1986); “El juicio” (1989); “El juicio que cambió al país” (1995); “ESMA: el día del juicio” (1998); “Juicio a las Juntas. El Nüremberg argentino” (2002); “Los días del juicio” (2010); “Proyecciones de la memoria” (2011). En este artículo se indagará en la construcción de la identidad del sobreviviente, a partir del análisis de estos registros audiovisuales, abordándolo en tanto sujeto colectivo, entendiendo que la reflexión en torno a los sobrevivientes es necesaria, como tarea hacia el pasado pero también, en pos del presente, de los derechos humanos, la justicia y la memoria.
Irse o volver: entre el drama y la comedia. Exiliados económicos en el cine argentino (2001 - 2011)
Authors: Chelotti Verónica
Published: August 2021

El objetivo de este artículo es analizar la representación de los exiliados económicos argentinos en el cine de ficción producido en Argentina entre los años 2001 y 2011. Nos centraremos en el análisis de las estrategias y los recursos que utilizan los filmes para construir los personajes, teniendo como hipótesis que dichas construcciones refuerzan los prejuicios que provienen del mundo real. En segundo lugar proponemos indagar sobre el contexto histórico representado: la crisis económica, política y social argentina del 2001. El corpus fílmico está compuesto por las películas: Lugares comunes (Aristarain, 2002) y Güelcom (Blanco, 2011), ficciones producidas en distintos momentos históricos relevantes para abordar la emigración a España, y el retorno hacia Argentina. El abordaje propuesto entiende al cine como artefacto de memoria, que permite mirar el pasado que se elige recordar, a la vez que da cuenta de lo que se quiere olvidar.
Mujeres históricas en las miradas documentales: ¿en búsqueda de la identidad?
Authors: Trombetta Jimena Cecilia
Published: August 2021

Las representaciones de las mujeres históricas en los audiovisuales se multiplicaron con la cuarta ola feminista y las nuevas tecnologías (que efectivamente brindaron una producción de fácil acceso). Con la finalidad de analizar el modo en que los documentales y serie para televisión problematizaron la creación de una memoria sobre figuras como Eva Perón, Victoria Ocampo y Alicia Moreau, tendremos en cuenta el concepto de identidad propuesto por Hall ([1996] 2003) para analizar desde una mirada feminista Evita, otra mirada (2009) de Manuel Gómez y producción y guion de María Teresa Mazzorotolo; Sello Argentino: Alicia Moreau de Justo (2012) de Andrés La Penna y Victoria Ocampo (2010) de Gabriel Di Meglio en el marco de la serie Bio.Ar (2009).
Los internados del miedo: cuando la realidad supera la ficción
Authors: Gruber Mónica
Published: August 2021

Los periodistas Montse Armengou y Ricard Belis realizaron el documental Los niños perdidos del franquismo (Els nens perduts del franquisme, 2002) para la cadena TV3 de Televisio de Catalunya, España. El material fílmico resumía solo una parte de lo que volcarían luego en un libro homónimo. Finalizada la pesquisa, las denuncias seguían llegando. Las víctimas querían que alguien las escuchase. Tal como señala Belis, no importaba que no existiesen documentos probatorios ya que las denuncias sobraban y había que atenderlas. De ese modo, los realizadores encaminaron sus pasos hacia un ignoto episodio del pasado español. Los internados del miedo tranquilamente podría ser el título de una película de terror, pero no lo es, ya que la realidad, supera la ficción. Los internados del miedo (Els internats de la por, 2015) de Montse Armengou y Ricard Belis recoge el testimonio de las víctimas de vejaciones, privaciones y hasta de experimentos médicos en los internados para niños de la época franquista. Hospitales Psiquiátricos, Preventorios, Casa Cuna e Internados escribieron las páginas más deleznables de la historia española, en las que la tortura, la violación, el trabajo esclavo de menores y la venta de niños, formaron parte. Nos proponemos abordar este material documental para ayudar a restituir la voz y la identidad de las víctimas silenciadas. ¿Puede haber sido la pobreza una de las causas de su situación? ¿Qué sucedió con los hijos de madres solteras? ¿Y aquellos cuyos padres eran reconocidamente antifranquistas? Estas y otras preguntas orientarán nuestra búsqueda. Trataremos de establecer cuáles pudieron ser algunas de las causas que colocaron a estos menores en una situación de mayor vulnerabilidad, convirtiéndolos en blanco fácil de dichas prácticas. No debemos perder de vista que, el Estado, la Iglesia y algunas empresas en flagrante connivencia fueron los ejecutores de un macabro y sistemático programa.
Estratégias de Resistência dos Artefatos Políticos de Zuzu Angel
Authors: Adverse Angélica
Published: August 2021

Nos anos de 1970, a estilista/designer Zuzu Angel engajou-se em defesa da democracia por intermédio de suas criações. Após o assassinato do seu filho Stuart Angel pela ditadura militar brasileira (1964-1985), ela iniciou intervenções críticas com intuito de denunciar a violência do Estado. Para tanto, concebeu coleções representando os conflitos e a tortura utilizada pelo regime militar contra prisioneiros políticos. Em 1971, realizou um desfile narrando por meio de estampas, bordados e textos, testemunhos sobre a história contemporânea brasileira. O vestido intitulado Anjo tornou-se a peça icônica da coleção a partir da qual ela bordou uma narrativa visual denunciando a necropolítica. A partir dessa criação, analisaremos o artefato político, servindo-nos da pesquisa de Winner (1980) a fim de propor uma correspondência com o Design Crítico. Seguindo as noções apresentadas por Dunne e Raby, analisaremos a ação política e o pensamento crítico no design. Nesse aspecto, nos deteremos sobre o sentido de política por autores como Arendt (2002), Benjamin (2012) e Bensaïd (2008). Por fim, apresentaremos a análise de Disalvo (2012) e Mouffe (2000) a respeito do Design Adverso e o sentido do agonismo. A proposta é pensar como os projetos em Design e Moda de Zuzu Angel transfiguraram-se num confronto político, sendo uma resistência à ditadura militar brasileira. Investigaremos como o estilo de moda possibilitou ao seu trabalho em design subverter as orientações sobre a usabilidade e função. Pelo campo conceitual, Zuzu Angel também aproximou-se das intervenções artísticas,performatizando sentimentos como a perda, a dor e o silêncio.
Percepción y recepción desde la mirada del diseñador gráfico. Relaciones dialécticas entre los enfoques perceptualistas y semióticos
Authors: Salguero Rosero José Rafael
Published: August 2021

El presente artículo confronta dos enfoques que un diseñador gráfico debe considerar al momento de trabajar una imagen visual o un objeto de diseño. El enfoque perceptualista que se fundamenta en la percepción sensible, frente al enfoque semiótico, que considera a la imagen como un signo. Analizar y confrontar estos dos enfoques es de interés, para dar respuestas fundamentadas frente a las continuas calificaciones que se escuchan sobre las imágenes visuales u objetos de diseño. Las categorías de feo, bonito, agradable, desagradable, entre otras, constituyen para algunos, escalas de valoración para un producto de diseño. Ante una debilidad cognitiva del proponente, en ocasiones, se consideran como válidas dichas valoraciones y se conceden cambios para las propuestas, lo que provoca que el diseño no cumpla con la función para la cual fue realizado.

Authors: Margadona Laís Akemi , Henriques Fernanda , Pereira de Andrade Ana Beatriz
Published: August 2021

Todavía se ven en el diseño contemporáneo prácticas centradas en procesos manuales, analógicos y, por qué no, nostálgicos. En este escenario, “#savethefilm” es el resultado de una investigación-acción en fotografía analógica en proyectos de diseño. Propone un diálogo interdisciplinario entre metodologías artesanales y digitales desde tres áreas principales: Fotografía, Diseño Gráfico y Diseño Digital. En términos metodológicos, las referencias incluyen el hibridismo en el diseño contemporáneo relacionado con los procesos fotográficos. Se desarrollaron experimentos visuales para validar las posibilidades de intercambio entre plataformas y áreas de conocimiento. La investigación aplicada presenta resultados prácticos híbridos, trasladados a entornos digitales. El objetivo final fue perfilar premisas creativas y proyectuales a producciones visuales que evocan la nostalgia y el coleccionismo.

ОЦЕНКА ВОЗМОЖНОСТИ ИСПОЛЬЗОВАНИЯ МОЛОЧНО-БЕЛОГО КВАРЦА НОВОТРОИЦКОГО МЕСТОРОЖДЕНИЯ ДЛЯ ПОЛУЧЕНИЯ ВЫСОКОЧИСТОГО КВАРЦА (HPQ), ЮЖНЫЙ УРАЛ
Authors: Корекина Мария Александровна
Published: August 2021

Актуальность. В связи с истощением запасов кварцевых месторождений прозрачного и полупрозрачного гранулированного кварца, являющихся традиционными источниками для получения высокочистого кварца (HPQ) для нужд высокотехнологичных отраслей производства, актуальной является оценка возможности использования для этих целей ранее не востребованных месторождений молочно-белого кварца. Цель. На основании изучения микроэлементного состава исходных и глубокообогащенных проб молочно-белого кварца разных генетических типов Новотроицкого месторождения выполнить оценку возможности их использования для получения высокочистого кварца (HPQ). Методы. Оценка перспективности кварцевого сырья дана на основе детального изучения петрографических особенностей и микроэлементного состава молочно-белого кварца методом ICP-OES спектроскопии. Результаты. Молочно-белый кварц месторождения крупно-гигантозернистый, интенсивно деформированный, разбит системой трещин, с резкими контактами с вмещающими чередующимися слюдистыми сланцами и кварцитами. В центральной части крупно-гигантозернистый кварц блокованный и разлистованный. В приконтактовой части кварц более минерализован, рекристаллизован, с содержанием новообразованных зерен в разных генетических типах от 3 до 50 %. Новообразованные зерна локализуются по полосам деформации, не содержат минеральных и флюидных включений и характеризуются высокой степенью чистоты. Во всех генетических типах, за исключением рекристаллизованного кварца с содержанием новообразованных зерен ~ 50 %, установлены высокие концентрации элементов-примесей, суммарно превышающие предельно допустимые для HPQ кварца. Это связано с наличием большого количества флюидных включений и трудностью их выделения из зерен кварца, а также сложностью удаления минеральных сростков с кварцем. Для получения высокочистого кварца пригоден интенсивно рекристаллизованный кварц с суммарным содержанием новообразованных зерен >50 % и элементов-примесей менее 50 ррm
Twitter, internautas vecinos y los intersticios de la polarización política
Authors: Juares Wanda , Ferreyra Silvana
Published: August 2021

Las redes sociales muestran que el espacio público virtual puede deconstruirse en una multiplicidad de esferas. Para algunas lecturas, esa fragmentación fomenta la polarización y reproduce las llamadas “cámaras de eco”. Desde otras ópticas, la superposición de públicos es lo que habilita la circulación de los mensajes. Siguiendo esta última línea, el artículo propone un análisis de los internautas que siguieron por Twitter a los candidatos a Intendente en el Partido de General Pueyrredón (Argentina) durante la campaña electoral de 2019. A partir de allí, nos proponemos abrir algunas líneas de reflexión acerca del debate sobre las limitaciones o las capacidades democráticas del espacio público virtual. Nuestra hipótesis es que existe un espacio público virtual local poblado por un tipo de usuarios –al que denominamos internautas vecinos– que puede pensarse como una suerte de intersticio subnacional en el marco de la polarización política reinante a nivel país. Para el seguimiento y análisis de los internautas se utilizó el lenguaje R. En primer lugar, reconstruimos el corpus de “seguidores” mediante la elaboración de una base de datos que nos permite identificar cercanías y distancias entre ellos en el mapa político. En segundo término, visualizamos y analizamos las palabras más frecuentes en las biografías de los seguidores de los candidatos para identificar manifestaciones que trasciendan las comunidades políticas o ideológicas.

Published: August 2021

This study covers 3 main problems, namely (1) the definition of verbs in Arabic and English (2) what are the similarities and differences between them (3) how to predict problems regarding verbs in Arabic. This study uses a qualitative study of literature. All data in this study were generated through the documentation method and to analyze the data researcher using a descriptive approach by comparing verbs in Arabic and English. And the results of this study indicate that verbs in Arabic and English are every word that indicates something that happened at a certain time. But between the two have similarities and differences. The similarities between the two are in the aspects of definition, sign, and division. The differences include division and marks. Verbs in Arabic are divided into 3, while in English are divided into 4. Verbs in Arabic and English also have different characteristics. The prediction of the problem about verbs in Arabic when teaching them to students is that verbs which have differences will be difficult for students to understand, while verbs that have similarities will be easily understood by students.

Published: August 2021

The subject of the article is proposed proprietary M toxicity indicator, which is based on the assumption that CO2 emissions are a measure of the correctness of the combustion process. For this purpose, gaseous exhaust compounds such as hydrocarbons, nitrogen oxides, carbon monoxide and carbon dioxide were measured and analyzed. The test object was a motorcycle, equipped with an gasoline engine with a displacement of 0.7 dm3 and a maximum power of 55 kW. The tests were carried out using the PEMS (Portable Emissions Measurement System) AxionR/S+. The exhaust emissions measurement was done in line with the WMTC (World Motorcycles Test Cycle) certification test, dedicated to vehicles in this category. The test consists of three parts, each of them lasts 600 seconds and has a different maximum speed value. The test was performed on a single-roller chassis dynamometer, designed for testing two-wheeled vehicles. The toxicity indicators and rotation speed results were presented as a function of time.

Published: August 2021

This paper explores the employees' readiness in the manufacturing sector for the fourth industrial revolution (4IR) vis a vis the 10 critical skill-sets identified by the World Economic Forum (WEF). We took a critical review of relevant theories and highlighted pragmatic solutions. Data collection for this study was obtained through a questionnaire among the employees of a brewing production plant in Nigeria. Using the 5-point Likert scale, 231 copies of the questionnaire were administered to workers on site. The study results are reported using a sample t-test to represent the values of Mean (M), Standard Deviation (SD), and Cronbach Alpha to test for the instrument's internal consistency. The analysis results revealed that most skillsets that require continuous career and employability in the 4IR are seen as low among the sampled organization employees, with an average mean score of less than 3.41. Interestingly, service orientation and people management skills are ranked the highest readily available skill among the workers. Many studies look at graduate work readiness, while attention to current employees' context is just beginning to gain traction.

The main aim of the paper was to establish the effect of operating cash flow on stock return of firms listed in NSE. The study was informed by Free Cash Flow (FCF) theory. Census survey was adapted to review financial statements for 29 listed non-financial firms at NSE that had consistent data for all the study variables. Secondary data was extracted for 12 years from 2007-2019 with the aid of a data collection sheet. Explanatory research design which is panel in nature was followed by this study. Both descriptive and inferential statistics were used in data analysis. Panel data regression was used to make inferences and test research hypothesis. Fixed and Random effects methods were used to analyze the balanced panel data using STATA statistical package and Hausman test established that Random effect model was the most ideal method to analyze data in this study. The findings indicated that operating cash flow positively and significantly influenced the stock returns for firms listed at NSE. The study concludes that operating cash flow information affects stock returns. Therefore, the study advocates for firms to increase their levels of operating cash flows through prudent utilization of cash resources since it enhances the stock returns.

Published: August 2021

Language affects society because linguistic forms treat men and women discriminatively as a reflection of the strong influence of language on the culture or habits of the speaking community. This study aimed to describe the representation of gender in speech and language politeness of senior high school and vocational school students in Samarinda City and Kutai Kertanegara Regency. The method used in this research was descriptive qualitative. The results of this study showed first, for the speech form by female students towards female teachers, they dominantly used the following forms: positive speech, expressive speech, and assertive speech. Second, for the speech form of female students towards male teachers, they preferred the form: expressive speech and assertive speech. Third, for the speech form of male students towards female teachers, they used the following forms: positive speech, commissive speech, and assertive speech. Fourth, the speech form of male students towards male teachers was expressive. Fifth, gender representation in student’s language politeness showed that female students were more likely to comply and male students were more likely to deviate from the principles of linguistic politeness. This study concludes female students followed the principle of language politeness towards female teachers. Male students expressed more deviations towards male teachers.
O VIDENTE AMÓS E A POLÍTICA: NEOASSÍRIOS E ARAMITAS NO QUADRO POLÍTICO DOS PROTESTOS EM ISRAEL NORTE NO SÉCULO VIII A.E.C.
Authors: Santos João Batista Ribeiro
Published: August 2021

A questão da origem camponesa de Amós tem situado o debate acerca da sua atuação em torno das explorações econômicas pelas elites governantes, deixando pouco abordadas no seu livro as disputas de autoridades institucionais do antigo Israel. No contexto histórico interno, encontram-se a abertura das fronteiras e a fluidez das identidades resultantes das relações diplomáticas israelitas iniciadas no século IX no período da dinastia omrida. Por um lado, isso levou ao desenvolvimento econômico em Samaria, a capital; por outro, resultou no empobrecimento de grupos sociais produtivos do setor rural, por causa da alta tributação da terra e da produção. No contexto regional, o início do processo de provincialização no sul do Levante Operado pelo império neoassírio somou-se aos conflitos de fronteiras entre Israel Norte (“Reino do Norte”) e Aram-Damasco, o que refletiu na economia e agravou a crise política israelita. Em perspectiva, o corpus profético projeta uma visão de mundo política: as decisões do rei devem contemplar os benefícios aos pequenos produtores e comerciantes excluídos das grandes rotas comerciais. Metodologicamente, realizaremos uma operação historiográfica comparativa, porque analisaremos fontes bíblicas e extra-bíblicas contemporâneas às representações literárias proféticas do Livro de Amós. Nossa pesquisa pretende concluir que a atuação de Amós e o que ele representa historicamente se encontram vinculados inicialmente a essa conjuntura político-econômica internacional.

Simulations of Nearest Teammate-Based Soccer Match-Plays with Different Formations
Authors: Scotognella Francesco
Published: August 2021

Formation in soccer is among the most important tactical choices for a successful match.Herein, the simulations of 420000 match-plays have been performed varying the formation, the number of opponents that are actively pressing the team, the speed of the opponents in attempting a pass interception. Dribbling has been neglected. The match-play ends either with a successful series of passes from a central back to the line of the strikers or with the opponents that steal the ball. In this work, I demonstrate that 3-4-3 formation, which is among the most employed formations, relates to the highest probability of success.

After introducing a probability distribution, determining the sum of n independent and identically distributed random variables is one of the interesting topics for authors. This paper presents the probability density functions for the sum of n independent and identically distributed random variables such as Shanker, Akash, Ishita, Pranav, Rani, and Ram Awadh. In order to determine all aforementioned distributions, the problem-solving methods are applied which is based on the change-of-variables technique.
Acupressure and Dementia - A Review of Current Evidence
Authors: Ooi Soo Liang , Drew Gillian , Pak Sok Cheon
Published: August 2021

Introduction: Dementia is a cognitive decline with patients often exhibit behavioural and psychological symptoms, severely affecting the quality of life and placing a heavy burden on caregivers. Acupressure has reported benefits for dementia. This study aims to critically review the available evidence for its use as a non-pharmacological therapy. Methods: Systematic search of major research databases for human clinical trials using acupressure as an intervention for dementia patients was conducted. Results were synthesised for the effects of acupressure on various outcome measures of interest for dementia.Results: Twelve clinical trials (N=973), including eight randomised control studies, were included in this review. The study sample was predominantly institutionalised residents with moderate to severe dementia. Baihui (GV20), Shenmen (HT7), Fengchi (GB20), Neiguan (PC6), Sanyinjiao (SP6), and Yingtang (EX-HN3) were the most used acupoints for intervention. Acupressure techniques employed in these clinical trials vary greatly with no standardised approach. This review finds inconsistent evidence in the effectiveness of acupressure in reducing agitation and behavioural disturbances. However, the treatment appears to improve their ease of care and reduce physical stress. Affixing acupressure devices on selected acupoints can also potentially improve psychiatric pain, anxiety, and depression. Long-term (6 months) treatment can potentially improve the cognitive function, activities of daily living, and quality of life of patients with mild to moderate dementia. The effect of acupressure on sleep disturbances remains unclear. Conclusion: More high-quality research on acupressure is needed to fill the gaps in knowledge and inform better care for dementia patients in the future.

A clinical and immunological analysis of the use of antiviral agent Inosine Pranobex (IP) as postoperative drug therapy in patients with cervical intraepithelial neoplasia (CIN) associated with human papillomavirus (HPV) is performed. It is known that IP has a high anti-relapse activity adapted to the mechanisms of HPV elimination (through the sequence of oncoproteins E5, E6 and E7, a decrease in the synthesis of interferons (IFNs) occurs and resistance of HPV-infected cells to IFN is formed). In this work, a number of statements justifying the priority of IP in the treatment of patients with CIN associated with HPV is covered, namely that IP induces trained immunity, differentiation of the Th1 subset of CD4+ T cells and proliferation of CD8+ T cells. Conclusion. Inosine Pranobex should be considered as the medication of choice for postoperative monotherapy in patients with HPV-associated CIN. Inosine Pranobex is characterized by mechanisms of action in both virus-infected cells and through the activation of innate and adaptive immune cells.

Vaginal embryonal rhabdomyosarcoma is a relatively rare tumor, which is more commonly diagnosed in children under three years of age and is rarely associated with organ-sparing treatment. Neoadjuvant chemotherapy followed by radiotherapy or surgery can be currently used as local tumor control. A clinical case of vaginal embryonal rhabdomyosarcoma in a 5-year-old girl is presented. Considering the tumor response to polychemotherapy, high dose rate intracavitary radiation therapy (brachytherapy) was chosen as the method of local control. Brachytherapy reduces the need for surgery and radiation of large regions in children and enables young patients to realize their reproductive function in the future. Key words: brachytherapy, management strategies, embryonal rhabdomyosarcoma

Objective. To study the effectiveness of the use of Acilact Duo for relieving the symptoms of atrophic vaginitis against the background of antiestrogen therapy. Patients and methods. The study included patients of reproductive age (n = 21) who were treated with goserelin (10.8 mg once every 3 months) in combination with tamoxifen (20 mg per day) for previously diagnosed breast cancer (luminal A type). Inclusion criteria were: age 28–45 years, complaints of vaginal dryness and micro-cuts, dyspareunia, breast cancer in anamnesis. Microscopic and bacteriological examination of the vaginal discharge was carried out. Patients filled out an individual questionnaire on the symptoms of atrophic vaginitis and dynamics of psycho-emotional state according to the Spielberger–Khanin scale. Results. The most common patients’ complaints were: dryness (up to 6.1 points) and the presence of vaginal micro-cuts (1.5 points), dyspareunia (1.3 points). After the course of treatment with Acilact Duo, the severity of symptoms decreased by 1.5 times. The assessment of psychological status demonstrated a low subjective evaluation of health and quality of life (36.7 ± 1.4 points). Twelve days after treatment, a mean anxiety score improved and amounted to 30.9 ± 0.6 points (р < 0.05). The intensity of vaginal microbial colonization in atrophic vaginitis is low and characterized by the absence of lactoflora and the predominance of enterobacteriaceae, atopobium vaginae, staphylococci, streptococci and peptostreptococci. After local therapy with Acilact Duo, there was an increase in colonization by lactobacilli (by 5.1 times, р < 0.05), a decrease in the level of colonization by streptococci (by 1.7 times, р < 0.05), staphylococci (by 2 times, р < 0.05), peptostreptococci (by 4.3 times, р < 0.05) and enterobacteriaceae (by 4 times, р < 0.05). Conclusion. A short 10-day course of treatment with Acilact Duo for patients with atrophic vaginitis can significantly reduce the severity of symptoms and improve the quality of life of women of reproductive age.

Objective. To study the results of electromyostimulation using an electrical device Tonis in patients with minimal signs of postpartum pelvic floor trauma. Patients and methods. The study included 24 women aged 20–32 years (27.4 (24.4; 29.1)) who were observed 6–12 months after delivery of their first child through vaginal childbirth in a cephalic presentation and whose examination revealed minimal signs of pelvic floor trauma or dysfunction. The electromyostimulation trainer Tonis was used 20 minutes daily (postpartum rehabilitation program) for 3 months. Results. After 3 months of training, in all patients, previously minimal complaints ceased. The POP-Q measurements significantly improved almost in all patients: the uterus was in a higher position, the topography of both the anterior and posterior vaginal walls improved, and the genital hiatus narrowed. Conclusion. Transperineal ultrasound showed a statistically significant improvement in the height of the central tendon of the perineum and in the muscle mass, the number of patients with muscle diastasis decreased, urethral hypermobility also decreased.

Objective. To identify risk factors for acute respiratory viral infections (ARVI) (influenza and novel coronavirus infection (NCI) COVID-19) in pregnant women and evaluate the effectiveness of pharmacological prevention. Patients and methods. During the first phase, 152 individual medical records of pregnant women were retrospectively studied: 102 women (the first main group) with acute respiratory viral infections and 50 pregnant women who had no acute respiratory viral infections (the control group). The second phase was a prospective comparative study: the second main group (n = 100) – pregnant women who received recombinant interferon α-2b (IFN-α2b) with vitamins E and C as preventive treatment; the comparison group (n = 100) – without preventive treatment. Results. Risk factors for the incidence of ARVI included anemia (χ2 = 0.003), obesity (χ2 = 0.026), cardiovascular diseases (χ2 = 0.060), diabetes mellitus (χ2 = 0.050), frequent ARVI in medical history (χ2 = 0.028), nicotine intoxication (χ2 = 0.008), urinary tract infections (χ2 < 0.001). The second phase: 10% of pregnant women who received preventive treatment had mild forms of influenza and NCI; 2% of women had a moderate form. In the second main group, 33% of pregnant women were sick (OR = 2.852, 95% CI = 1.354–6.005, χ2 = 0.005): 26% of women had a mild form, 6% of women had a moderate form and 1% of women had a severe form. In the second main group, threatened miscarriage (χ2 < 0.001), preterm birth (χ2 < 0.001), gestational pyelonephritis (χ2 = 0.006), placental insufficiency (χ2 < 0.001), pre-eclampsia (χ2 = 0.006), congenital anomalies of the fetus (χ2 = 0.017) and intrauterine infection (χ2 < 0.001) were more frequent. Conclusions. Among risk factors for ARVI during pregnancy were anemia, obesity, diabetes mellitus, and nicotine intoxication. Preventive treatment with recombinant IFNα-2b with vitamins E and C reduced the incidence of acute respiratory viral infections in pregnant women by 2.8 times and improved perinatal outcomes by 4.7 times.
