Can Vitamin D Positively Impact Sarcopenia Severity Among Older Adults with Hand Osteoarthritis: A Review of the Evidence
Authors: Marks Ray
Published: October 2023

Aim
This review examines the research base concerning hand osteoarthritis and changes in muscle mass and quality known as sarcopenia and the possible use of vitamin-D supplementation for reducing this potentially adverse functionally disabling state.

Methods
Publications detailing a possible link between hand osteoarthritis manifestations and sarcopenia, plus those discussing vitamin D as a possible intervention strategy for minimizing sarcopenia in the older adult were systematically sought and reviewed.

Results
Collectively, data reveal hand osteoarthritis in the older population is common, and is possibly affected by age as well as disease associated muscle mass declines. Vitamin D, a powerful steroid required by the body to foster many life affirming physiological functions may help reduce the degree of any prevailing sarcopenia and thereby some degree of hand osteoarthritis disability.

Conclusions
Older individuals with hand osteoarthritis, as well as healthy older adults at risk for sarcopenia are likely to benefit physically from efforts to clarify the extent of this association and if indicated, to examine and intervene thoughtfully to maximize muscle composition as well as safe vitamin D levels where subnormal. Researchers can make highly notable impacts in multiple spheres in this regard and are encouraged to do so.
BIM Data Structure in the Building Optimization: Methodology for Model Development
Authors:   , Veselka Jakub
Published: October 2023

Building Information Modelling (BIM) is already an integral part of the construction process in the Czech Republic and worldwide. The main barriers to implementation are gradually being removed, and these models are being used in more and more parts of the construction industry. Another way of use is environmental analysis, which is gradually moving from the field of research projects to everyday practice. This dissertation aims to summarize the current environmental issues in the global context of the construction industry, analyze the use of information models for these calculations in different parts of the life cycle, and summarize the potential for optimizing building design. The text divides the construction design process into three main stages: initial, advanced, and detailed construction design. These stages replicate the levels of study, construction permit documentation, and construction shop drawing / manufacturing documentation (SD/MD). The operational, demolition and recycling potential phases are also addressed. The focal point of the thesis is the methodological guidance for developing information models for each of these stages, including the specification of appropriate environmental data and options for optimizing the design of the building at this stage. Several Czech and foreign case studies from the research and commercial sphere complemented the theoretical part for all defined design phases. The remainder of the thesis is devoted to a summary of discussions on the results of the case studies, practice recommendations, and a subjective outlook on future developments in this area.
High-Performance Concrete Mixtures Containing Glass Powder: Optimization of mechanical properties, durability, and environmental impacts for use in construction and design applications
Authors:   , Mariaková Diana
Published: October 2023

This thesis focuses on the use of glass powder from various sources. These are mainly waste glass that comes from shards from municipal waste and old glass from photovoltaic panels due to the end of the service life of these systems from the first generation. Another type of glass investigated is a secondary product of glass production. By-products are created in many branches of industry; the glass industry is a significant producer in this respect. Two types of glass from different glass plants were analyzed. The initial study was already published in 2019 and was among the first in the Czech Republic; therefore, it was desirable to follow up with further research. Since the use of glass powder in concrete, in addition to the possibility, raises many fundamental questions, this research analyzes the materials as such, especially from the chemical, physical and toxic points of view. Repeated experiments were carried out in the thesis, and concrete samples with these materials were subsequently tested. The main point of interest was verifying the potential alkali-silica reaction (ASR), which was assumed due to the use of glass, which can catalyze the reaction. ASR testing took place in two iterations, international and national testing procedures were chosen. The potential ecotoxic threat of glass was viewed similarly significantly. Glass from photovoltaic panels and glass as a secondary production product was slightly hazardous in toxicity tests. However, after encapsulation in concrete, all results were at safe levels below the limit. Due to the subsequent development of tiles and masonry applications, it was necessary to test these potentially undesirable properties thoroughly. Thus the assumption of a positive effect of glass powder on the concrete mixture in terms of ASR and toxicity was confirmed for most mixtures. At the same time, a methodology was proposed for the evaluation of building materials from the point of view of ecotoxicity.

Published: October 2023

This paper presents first stage of supersonic flow modelling in gas circuit breakers without an arc. Flow characterisation focused on shock and flow separation phenomenon. Velocity deceleration caused by shock will play a significant role in determining arc cooling performance and will impact thermal interruption capability. Gas properties such as specific heat ratio, density, and viscosity influenced the flow characteristics including shock location, strength and the flow separation process.
Molecular Dynamic Simulation of the Effect of Initial Surface Temperature on Arc Erosion Due to Ion Bombardment
Authors: Wang Xin , Matharage Shanika Yasantha , Wang Zhongdong
Published: October 2023

This study focuses on the effects of initial surface temperature on arc erosion caused by ion bombardment. The simulation results show that higher surface temperature leads to a greater number of lost Cu atoms and an increased size of the erosion crater. This is due to the ability of the incident ions to have a greater sputtering yield at higher temperatures. Moreover, the Cu atoms tend to agglomerate and form clusters after ion bombardment while leaving the surface.

Published: October 2023

This work integrates experimental and MD simulation approaches to study the role of graphene in G-Cu-W composites. Arcing tests were conducted on G-Cu-W and Cu-W contact samples under a 5kA peak current. Experimental results show that adding graphene leads to a lower surface roughness of the sample following arcing. MD simulation results indicate that the G-Cu-W model exhibits a smoother surface and fewer lost metal atoms than the Cu-W model due to the protective effect of graphene layer.
Optical Investigation of a Spark Gap for DC Protection around Current Zero
Authors: Methling Ralf , Schmausser Sebastian , Kellermann Marco , Ehrhardt Arnd , Gortschakow Sergey , Uhrlandt Dirk , Gonzalez Diego
Published: October 2023

The applied experimental setup consists of a pair of fixed electrodes forming a short gap in air. The electrodes are connected with a thyristor forming a parallel current path. Once the thought flashover ignited arc has burnt a given time in the range of several hundreds of microseconds, the thyristor will be fired causing a commutation of the current in the semiconductor path. Hence, the current through the electrode gap will be reduced. The extinguishment of the arc permits the creation of a current zero in the gap. The focus of the experimental work is set to the analysis of the arc plasma during the DC phase and its distinction in the current extinction phase (current zero). High speed camera observation and optical emission spectroscopy are carried out and combined with the electrical measurements.

Auswege aus der Kunst. Soziale Plastik, Aktivismus und Post Art
Authors: Berg Karen van den
Published: October 2023

Der Beitrag befasst sich mit dem Erbe von Joseph Beuys' Konzept der Sozialen Plastik. Er bestimmt Beuys' Verständnis Sozialer Plastik im Kontrast zu aktuellen Ansätzen Sozial Engagierter Kunst. Hierbei wird gezeigt, dass ein wesentlicher Unterschied zwischen Beuys' Kunstverständnis und heutigen Ansätzen darin besteht, dass Beuys die Institutionen der Kunst erweitern wollte, ohne die individuelle Autorschaft aufgeben zu wollen, während sich sozial engagierte Künstler:innen zumeist auf Augenhöhe in Communities mit nicht-künstlerischen Aktivist:innen organisieren. Dagegen erklärte Beuys Praktiken aus allen möglichen anderen Gesellschaftsfeldern zur Kunst, weil er allein der Kunst die Kraft zutraute, einen grundlegenden gesellschaftlichen Wandel zu bewirken.
Hegemonie und sozialer Wandel
Authors: Lluis Conrad
Published: October 2023

In Zeiten vielschichtiger Krisen stellt der beschleunigte soziale Wandel Spaniens zwischen 2011 und 2016 ein Paradebeispiel für polarisierte Gesellschaften dar. Die Platzbesetzungen der Indignados (der »Empörten«) und die ihnen folgenden Entwicklungen in Zivilgesellschaft und Politik veränderten das Land grundlegend. Mit Diskursanalysen, Interviews, Ethnographien und einer historischen Einbettung rekonstruiert Conrad Lluis in einer umfassenden empirischen Studie die politischen Umbrüche Spaniens. Parallel dazu entfaltet er im Dialog mit der Empirie eine Hegemonietheorie, die Laclau und Mouffe weiterdenkt, und ebnet damit den Weg für eine postfundamentalistische Sozialtheorie.
Observing Conflict Escalation in World Society
Authors: Bösch Richard
Published: October 2023

How do conflicts escalate? This is one of the major questions in conflict research. To offer further answers, Richard Bösch follows a tripartite agenda: First, he develops a constructivist methodology for the study of conflict escalation embedded in a Luhmannian systems theoretical world society perspective. Bösch argues that conflicts can be observed as social systems and he looks at the process of conflict escalation by analysing communication. Second, this analysis offers two case studies: the Maidan protests in Ukraine 2013-2014 and Mali's crisis 2010-2012. Third, it gives insights on how systems theoretical research can be beneficial for Peace and Conflict Studies.
Ethische Perspektiven des gesellschaftspolitischen Managements zur Bekämpfung der Corona-Pandemie
Authors: Lehmann Udo
Published: October 2023

Während der Covid-19-Pandemie wurden ab März 2020 weltweit zahlreiche Maßnahmen erlassen, die zeitweise zu drastischen Einschränken praktisch aller Bereiche des privaten und öffentlichen Lebens führten. Dies stellte auch die Durchführung von Forschung und Lehre an Universitäten vor besondere Herausforderungen. Während Vorlesungen und Seminare noch vergleichsweise problemlos und zeitnah in geeignete Online-Formate überführt werden konnten, erforderten nur in Präsenz durchführbare Praxisformate ein deutlich höheres Maß an Vorplanung. Um die Sicherheit von Studierenden und Lehrenden zu gewährleisten, waren die Maßnahmen in folgenden Bereichen dabei sorgfältig hinsichtlich ihrer (teilweise unbeabsichtigten) Konsequenzen abzuwägen: a) Organisatorische Maßnahmen wie die Verkleinerung von Kursen und die Optimierung von Laufwegen, b) Tragen eines Mund-Nase-Schutzes, c) Technische Maßnahmen wie die Installation geeigneter Trennwände. Die Erfahrungen an der Universität des Saarlandes haben gezeigt, dass der Betrieb von chemischen Laboratorien in Forschung und Lehre unter pandemischen Bedingungen durch eine Kombination verschiedener Maßnahmen möglich ist, ohne Beteiligte einem nachweisbar erhöhten Infektionsrisiko auszusetzen oder die im Labor ohnehin geltenden Sicherheitsstandards nennenswert zu kompromittieren.

Die Praxis des Nudging
Authors: Seitz Tim
Published: October 2023

In der Praxis des Nudging wird die Sanftheit der Verhaltensbeeinflussung zum epistemischen Problem: Verhalten soll unbemerkt beeinflusst werden, doch erst durch den Nachweis von Verhaltensänderungen gewinnt das Konzept seine Überzeugungskraft. Tim Seitz untersucht ethnografisch die praktische Herstellung von Nudges. Er rekonstruiert miteinander verwobene Prozesse der Problematisierung, Lösungsentwicklung und Evidenzproduktion und macht deutlich: Nudging muss die Experimentalbedingungen immer erst schaffen, unter denen sich sanft regieren lässt.
Lesen im Zeitalter der Künstlichen Intelligenz
Authors: Rötzer Florian
Published: October 2023

Wir stehen vor einem kulturellen Umbruch der Kulturtechnik Lesen, die mit der Erfindung der Schrift begann und über den Buchdruck in die Digitalisierung mündete: Mit den »Sprachmodellen« der lernenden Künstlichen Intelligenz treten neben die Menschen plötzlich unmenschliche maschinelle Leser, die alle Texte rezipieren und zu neuen Texten verarbeiten können. Sie lesen Texte als binär codierte Informationsströme und verstehen das Geschriebene nicht, sondern lernen eine wahrscheinliche Wortkombinatorik - aus der trotzdem Unerwartetes geschehen kann. Florian Rötzer wagt eine Nachlese und beantwortet die Frage, ob KI die menschlichen Leser*innen verdrängt oder ob die Kulturtechnik des Lesens durch die neuen Einflüsse nur revolutioniert wird.
Hegels Phantasie
Authors: Vassilevski Ekaterina
Published: October 2023

Als »Zwischenreich«, »Drittes« oder »Mitte« bezeichnet, kommt der Imagination seit ihren Anfängen in der Antike die Rolle eines Mediums zu. Gleichzeitig bleibt ihr medialer Aspekt durchgehend ambivalent und prekär. Es ist Georg Wilhelm Friedrich Hegel, der die Imagination nicht mehr als subjektives Vermögen versteht, sondern als Kraft der »Entäußerung« und sie somit medial denkt. In einer bislang wenig beachteten Passage aus Hegels dritter Enzyklopädie von 1830 legt Ekaterina Vassilevski nicht nur die implizite Medialität der Imagination frei, sondern auch den in Hegels Denken verborgenen Begriff des Medialen.
Bildung als Welt- und Selbstverhältnis
Authors: Hollunder Korbinian
Published: October 2023

Bildung ist ein Transformationsprozess des Welt- und Selbstverhältnisses eines Subjekts. Das Bildungssubjekt nimmt hier eine zentrale Rolle ein, indem es sich zu seinen erworbenen Überzeugungen über die Welt und der Strukturiertheit seines eigenen Selbst verhält. Korbinian Hollunder macht den Beitrag des Subjekts in diesen transformatorischen Bildungsprozessen in Auseinandersetzung mit Subjekttheorien, Reflexionsmodellen und der Achtsamkeitstheorie transparent - und zeigt darüber hinaus, dass transformatorische Bildungsprozesse dem Bildungssubjekt Möglichkeitsräume eröffnen, sich Selbstbestimmung im eigenen Leben zu erarbeiten.
Ökonomie der Großzügigkeit

Published: October 2023

Lässt sich eine gute Zukunft durch Effizienz, Expansion und elaborierte Technik erreichen? Fred Luks kritisiert eine überzogene Orientierung an ökonomischen Leitbildern und veranschaulicht, wie sie im Gegenteil die Zukunftsfähigkeit westlicher Gesellschaften bedrohen. Stattdessen positioniert er die Großzügigkeit im Raum zwischen Technikeuphorie, Verzichtsmoralismus und Resignation und widmet sich ihren Auswirkungen auf verschiedene Themenfelder: Klima, Welthandel, Tierwohl, Digitalisierung und Selbstoptimierung. Diese Neuordnung des Diskurses zeigt, wie ein friedliches gesellschaftliches Zusammenleben möglich ist - auch über den Tellerrand der Nachhaltigkeit hinaus.
EIGENVALUES AND EIGENFUNCTIONS OF THE LAPLACE OPERATOR IN A SQUARE AND IN A CIRCLE WITH A WENTZEL BOUNDARY CONDITION
Authors:   South Ural State University, Chelyabinsk, Russian Federation, Goncharov N.S.
Published: October 2023

Abstract. Recently, in the mathematical literature, the Wentzel boundary condition has been considered from two points of view. In the first case, let us call it a classical case, this condition is an equation containing a linear combination of the values of the function and its derivatives at the boundary of the domain. Meanwhile, the function itself also satisfies an equation with an elliptic operator given in the domain. In the second, neoclassical case, the Wentzel condition is an equation with the Laplace–Beltrami operator defined on the boundary of the domain, understood as a smooth compact Riemannian manifold without an edge; and the external effect is represented by the normal derivative of the function specified in the domain. The paper considers the properties of the Laplace operator with the Wentzel boundary condition in the neoclassical sense. In particular, eigenvalues and eigenfunctions of the Laplace operator are constructed for a system of Wentzel equations in a circle and in a square.
ON THE IDENTIFICATION OF SOLUTIONS TO RICCATI EQUATION AND THE OTHER POLYNOMIAL SYSTEMS OF DIFFERENTIAL EQUATIONS
Authors:   Moscow, Russian Federation, Zaytsev M.L.
Published: October 2023

The authors previously proposed a general method for finding particular solutions for overdetermined PDE systems, where the number of equations is greater than the number of unknown functions. The essence of the method is to reduce the PDE to systems of PDE of a lower dimension, in particular, to ODEs by overdetermining them by additional constraint equations. Reduction of some PDE systems generates overdetermined systems of polynomial ODEs, which are studied in this paper. A method for transforming polynomial ODE systems to linear ODE systems is proposed. The result is interesting from a theoretical point of view if these systems of polynomial ODEs are with constant coefficients. The solution of such nonlinear systems using our method can be represented as a sum of a very large but finite number of oscillations. The amplitudes of these oscillations depend on the initial data nonlinearly. The Navier–Stokes equations and unified PDE systems obtained by the authors earlier can be transformed to such systems. The Riccati equation is also investigated. New special cases are indicated when it is possible to find its solution. Numerical estimates of the complexity of this method for practical implementation are presented.
TWO-PARAMETER METHOD OF DETERMININING STRESS INTENSITY FACTOR KI OF CRACK-LIKE DEFECTS USING HOLOGRAPHIC INTERFEROMETRY
Authors:   South Ural State University, Chelyabinsk, Russian Federation, Dilman V.L. , Utkin P.B.
Published: October 2023

A new method has been developed for finding the stress intensity coefficient and the nominal stress σox for a plate with a crack-like (elliptical) defect. As an experimental basis, the patterns of bands of absolute path difference obtained on the basis of the method of holographic interferometry are taken. Using Favre ratios and approximate decomposition of stress components for the plane case, the stress intensity coefficient and the nominal stress σox are determined. The difference of the proposed method is in a more accurate representation of the stress tensor in the vicinity of the vertex of a crack like defect. Such representation allows one to take the geometry of the defect into account. The values of the correction function calculated by the proposed method in the formula for theoretical determining of the intensity factor have been higher than those obtained by previously used methods. This indicates a possible underestimation of the magnitude of the intensity factor when using the previously proposed methods. In addition to using more precise formulas for the stress tensor, the approach implies considering the nominal stress and the intensity factor as independent parameters. Full consideration of the crack geometry and loading features is very difficult from a mathematical point of view; however, this property of the method allows partially compensating for the simplifications of the stress tensor analytic expressions. Also, this method makes it possible to determine the main stresses and the intensity of stresses in the vicinity of the vertex of the defect. The obtained formulas agree well with experimental results.
What is missing to understand sustainability?
Authors: Thomas Rosalba
Published: October 2023

Despite the enormous global problems linked not only to the ecological sphere, but also to the environmental, political, economic, social and cultural dimensions, humanity continues to consider that the discourse of sustainability has a close and unique relationship with nature. It is not like this. This text aims to make a deeper reflection on the historical context, interests and power relations that derive from considering sustainability as an alternative development model. More than a neutral discourse, sustainability must always land in a specific historical and spatial context, which allows it to adapt, and then perhaps become more operational and functional. The hypothesis places the media as simplistic and, at times partial interlocutors; but definitely not neutral, which prevents the individual from understanding the complex dynamics of the planet and the possible solutions to current problems. It is not only the fact that the media define what sustainability is, it is also important to reflect on how and why they do it.

Published: October 2023

The best practices of a university waste management considering innovation, impact, and future direction of sustainable universities involve a comprehensive approach that considers not only the environmental impact of waste but also the social and economic dimensions of sustainability. This is especially true for higher education institutions that are meant to educate most future business and social leaders of a country or a region, as is the case at Corvinus University of Budapest. The first step in waste management is to minimize the amount of waste generated. Corvinus achieve this by promoting a culture of sustainability on campus and encouraging students, faculty, and staff to adopt eco-friendly habits, such as using reusable bags, bottles, and containers, and minimizing the use of single-use items and encouraging the use of digital documents instead of paper. After reducing waste generation, the next step is to reuse and recycle as much as possible.Corvinus set up recycling stations that accept a wide range of materials, such as plastics, paper, and electronics. Additionally, Corvinus works with local organizations to donate gently used items, such as furniture and IT, instead of sending them to landfills.Corvinus track their waste generation and disposal to identify areas for improvement and evaluate the effectiveness of their waste management programs. By regularly monitoring and reporting on their waste management practices, Corvinus set goals for improvement and demonstrate their commitment to sustainability.Corvinus collaborate with industry, government, and community groups to find new and innovative solutions for waste management. This include partnering with local waste management organizations to develop sustainable waste management practices, as well as working with local businesses to reduce waste generation. Overall, a successful waste management program at a sustainable university requires a multifaceted approach that incorporates education, outreach, partnerships, technology, and monitoring. By implementing these best practices, universities can reduce their environmental impact, engage students, and staff in sustainable practices, and demonstrate their commitment to creating a more sustainable future.

Published: October 2023

Universities play an essential role in achieving Indonesia's 2060 carbon-neutral target. Emissions in the campus are mainly sourced from its electrical energy, transportation, and water use, along with other wastes. Electrical energy from solar is renewable energy, free from pollutants and noise pollution. This paper examines the sustainable energy performance of solar energy at the Universitas Islam Negeri Raden Fatah Palembang (UINRFP) and its development efforts. From August 2022 to March 2023, a solar power plant (SPP) operation with a capacity of 7.74 kWp has generated 6,281.5 kWh of electricity (28.55 kWh/day). Using a radiation factor of 0.8 and an equivalent sun hour of 4.61 (3-5 hours/day), the rooftop capacity of all buildings on Jakabaring Campus is 2,000 kWp, the potential of SPP electricity of UINRFP will exceed 39.3% compared to the 2022 electricity demand. If the capacity is, half the electricity generated from renewable energy meets 70% of the demand. Gradually UINRFP continues to develop its energy sources towards sustainable energy. The development of other research-scale renewable energy with hybrid solar energy and wind power for the aesthetic lighting function on the rectorate building has the potential to generate 290 kWh/year. In addition, micro-hydro energy sources from campus canals (water volume ±9,400 m3) and biomass are potential renewable energy sources at UINRFP for a sustainable campus in the future and contributing to reducing the impact of climate change.

Authors: Prozorovskyi D. V.
Published: October 2023

Aim. To trace developmental origins of surgical treatment of hammertoe deformity and determine the most commonly used methods of its correction based on the published literature analysis.
Material and methods. Publications from Google search, electronic databases PubMed, Google Scholar, archives of specialized journals and other relevant sources of scientific and medical information were analyzed.
Results. The article covers the developmental origins of surgical treatment of hammertoe deformity both in the historical aspect and at the current level. Attention is paid to soft tissue procedures including tendons, metatarsophalangeal joint capsule, and plantar plate. An overview of operative interventions on the bone apparatus, phalanges and metatarsal bones and the combination of these surgeries is also presented in the article. The disadvantages of the existing surgical treatments, their advantages and the ways for forthcoming research concerning the improvement of surgical care in the treatment of hammertoe deformity are identified.
Conclusions. The choice of a particular method of surgical correction between the phalangeal or metatarsal level, the feasibility of combining these interventions with restoring the integrity of the plantar plate and tendon reconstruction, remains debatable. Further study on these issues is a crucial task today for choosing the optimal method of hammertoe deformity correction.
A case of severe COVID-19 and influenza co-infection
Authors: Riabokon O. V. , Furyk O. O. , Kalashnyk K. V.
Published: October 2023

Aim. To analyze a case of severe COVID-19 and influenza co-infection in a 48-year-old female patient.
Materials and methods. The clinical course, specifics of diagnosis and therapy of the 48-year-old patient S., who was treated for severe co-infection of COVID-19 and influenza at Municipal non-profit Enterprise “Regional Infectious Clinical Hospital” Zaporizhzhіa Regional Council from 29.01.2023 to 17.02.2023, were analyzed. The diagnosis of COVID-19 was confirmed by the detection of SARS-CoV-2 Ag in nasopharyngeal swabs by the immunochromatographic method, and the diagnosis of influenza – by the influenza A viral RNA detection by the polymerase chain reaction method. Current regulatory documents were used when examining and treating the patient.
Results. It has been recognized that the unvaccinated 48-year-old female patient was at a risk group due to comorbid pathology (stage 2 hypertension, type 2 diabetes mellitus, grade 2 obesity) developed a severe course of COVID-19 and influenza type A co-infection. The course of co-infection was complicated by severe acute respiratory distress syndrome already on the 6th day of the disease. The diagnosis of COVID-19 was confirmed by a rapid SARS-CoV-2 antigen test. Treatment for COVID-19 was started immediately with the use of remdesivir, dexamethasone, and anticoagulants. However, despite the patient was given the treatment, his condition worsened due to the rapid progression of acute respiratory failure. The presence of clear clinical and laboratory signs of “cytokine storm” required the use of tocilizumab on the 7th day of the disease. Oseltamivir was commenced after receiving laboratory confirmation of influenza A by the PCR method on the 8th day of the disease. A complete etiologic interpretation of the diagnosis made it possible to prescribe a combination antiviral treatment which coupled with the timely additional initiation of tocilizumab, allowed obtaining certain positive dynamics after only five days of treatment with further improvement of the patient’s condition.
Conclusions. Our clinical observation has demonstrated the severe course of COVID-19 and influenza co-infection in the unvaccinated high-risk 48-year-old female patient due to the presence of comorbid pathology. The complete etiologic interpretation of the co-infection has made it possible to prescribe the combination antiviral treatment, which coupled with the additional correction of the immunotropic treatment has enabled to obtain the positive dynamics after only 5 days with further improvement of the patient’s condition

Materials and methods. The study involved 93 patients with MAFLD in combination with T2DM, who were examined and allocated to two groups. Group 1 consisted of 48 patients with non-alcoholic steatohepatitis (NASH) in combination with T2DM without small intestinal bacterial overgrowth (SIBO) syndrome. Group 2 comprised 45 patients with NASH in combination with T2DM and SIBO. The control group consisted of 25 apparently healthy persons. The ELISA method was used for quantitative determination of serum zonulin.
Results. When comparing parameters of liver functional activity and ultrasonographic findings of liver steatosis and fibrosis, a significant increase in the activity of ALT and AST was revealed in Group 1 – 67.22 ± 2.25 U/l and 52.97 ± 1.04 U/l (p < 0.001) and in Group 2 – 69.20 ± 1.52 U/l and 54.82 ± 1.10 U/l (p < 0.001) compared to those in the control group – 18.00 ± 1.01 U/l and 18.96 ± 0.82 U/l (p < 0.001) respectively, as well as an increase in the ultrasound attenuation coefficient (UAC) in patients of Groups 1 and 2 amounting to 2.94 ± 0.03 dB/cm and 2.92 ± 0.04 dB/cm, respectively, and also the liver stiffness (LS) in Group 1 – 8.06 ± 0.07 kPa and in Group 2 – 8.00 ± 0.06 kPa compared to those in the control group (p < 0.001).
When measuring the level of serum zonulin, a significant increase was revealed in patients of Group 1 – 61.69 ± 1.04 ng/ml and Group 2 – 89.39 ± 1.30 ng/ml compared to that in the control group – 16.76 ± 1.47 ng/ml (p < 0.001). Analyzing correlation coefficients in patients of Groups 1 and 2, a positive linear moderate association was found between the serum zonulin concentration and the activity of ALT, AST and UAC and LS.
Conclusions. The study resultsobtained have demonstrated the great diagnostic value of serum zonulin as a biomarker of intestinal permeability in NASH patients in combination with T2DM, and with or without SIBO.

Sinusoidal obstruction syndrome (SOS), previously known as hepatic veno-occlusive disease, is manifested by obliterating inflammation of the terminal hepatic veins, characterized by hepatomegaly, right upper quadrant pain, jaundice and ascites, and most often occurs in patients after hematopoietic stem cell transplantation and usually in those who received platinum-based drugs. Cases of SOS development in patients after transplantation of solid organs (lungs, pancreas, liver) are also reported in the world literature. These incidents are rare, and isolated and poorly studied after living-related liver lobe transplantation. The diagnosis is based on clinical signs, imaging techniques (according to ultrasound and radiological methods of examination), histological assessment of liver biopsy. Tacrolimus has been reported to be a causative agent that potentially plays a role in the pathophysiological mechanism of SOS.
Aim. To study the relationship between the use of prolonged-release tacrolimus and the development of SOS in patients after living-related liver transplantation.
Clinical case. In this article, we present a case of SOS after living-related liver transplantation which was associated with a toxic effect of prolonged-release tacrolimus (“Envarsus”). In a 55-year-old man, after living-related liver transplantation, high blood concentrations of tacrolimus associated with uncontrolled drug intake were detected. When performing a number of laboratory and instrumental methods of examination due to a massive ascites manifestation, the diagnosis of SOS was made. The study was carried out in accordance with the principles of the Helsinki Declaration. The informed consent was obtained from the patient for conducting the studies.
Conclusions. By ruling out other possible contributing factors, including an acute rejection crisis, it was concluded that prolonged-release tacrolimus (“Envarsus”) was the cause of SOS.
Pelvic veins ultrasound changes after surgical correction in patients with pelvic congestion syndrome
Authors: Havrylenko B. S. , Nykonenko A. O.
Published: October 2023

Pelvic congestion syndrome is a form of varicose disease, which is considered to be one of the main causes of chronic pelvic pain in women, which is associated with a violation of pelvic veins hemodynamics.
Pelvic venous disorders are invisible to clinicians due to the lack of pathognomonic symptoms and manual disease criteria, but it has significant consequences.
Today, one of the main diagnostic methods of pelvic venous disorders is a transvaginal US of pelvic veins, including gonadal veins (ovarian veins in women). Thanks to this non-invasive and simple diagnostic method that does not require specific preparation and has no contraindications, we have significant opportunities in diagnosis, as well as in the further evaluation of the postoperative results of surgical correction of pelvic congestion syndrome.
The aim of the study was to analyze changes of pelvic veins in patients with pelvic congestion syndrome before and after surgical intervention using the transvaginal US method.
Materials and methods. The study included 35 patients which underwent surgical treatment using open surgery and endovascular procedure between April 2019 and February 2022 with pelvic congestion syndrome. All patients underwent transvaginal ultrasound of the pelvic veins before surgery. A control examination was performed after surgical treatment in 4–6 months. The examination was performed on an expert-class ultrasound system “Toshiba Aplio 500” using all international standards for transvaginal examination of pelvic veins to evaluate the changes of illiac, paraovarian, parametrial and ovarian veins from the left side and from the right side in patients with pelvic venous disorders.
Conclusions. Transvaginal ultrasound of the pelvic veins can be considered one of the key diagnostic methods, with the help of which it is possible to investigate and evaluate hemodynamic disorders in the veins of the pelvis and pelvic organs in real time. Also, this method can be considered optimal for the control examination of patients who underwent surgical correction of pelvic congestion syndrome.
Ear to the ground. Searching for ourselves in each other
Authors: Stok Witold
Published: October 2023

An acclaimed Polish cinematographer and documentary film director describes his meeting with Sergey Paradjanov in the 1970s in Kiev. Stok found himself there in connection with the shooting of Piotr Studziński’s documentary film about one of Ukraine’s mathematicians. Despite the difficulties created by the Soviet totalitarian state to isolate Paradjanov, Stok managed to reach the director and also to watch his documentary film about the frescoes in Kiev at a special secret club screening. In his essay – a memoir – the author describes the differences between life in the Soviet Union and in more liberal Communist-ruled Poland. He characterizes Paradjanov’s artistic profile and his fate in the Soviet Union.
Filmmaking as Cultural Aggression
Authors: Shevchuk Yuri
Published: October 2023

The article discusses cinematic depopulation, the strategy of appropriation of the colonized by the colonizer widely used in the Soviet and post-Soviet cinema made in Ukraine and Russia and, until now, never analyzed in academic literature. The cinematic depopulation is a mode of filmic representation whereby a given ethnoscape (Ukraine) is cleansed of its national community (Ukrainians) and instead is populated by the colonizer (Russians) as if it were an integral part of his historical territory. As a form of cultural imperialism, this strategy has, until quite recently, been widely used in both Soviet and post-Soviet Russian and Ukrainian filmmaking to promote the idea of Ukraine conceivable outside of and without the Ukrainian language, culture, and other attributes of Ukrainian identity.
Religion, Female Sexuality and Magic in (Post)Modern Film
Authors: Vinczeová Barbora
Published: October 2023

The paper strives to investigate the relationship of female sexuality, magic and religion in film based on the comparison of two selected films. The three themes have been often seen as intertwined especially by religion, which has built an image of a female witch in alliance with the devil, or evil forces. The research aims to answer the question whether postmodern cinema embraces the combination of the aforementioned themes often associated, historically, with the notion of witchcraft practised especially by female witches. The scope of the research is limited to two films; however, the possibility to expand the research in the future and include newer films exists. Comparative methods and analysis are used throughout the paper. The paper is structured according to the analysed themes found in both films – Carrie (dir. Kimberly Peirce, 2013) and Thelma (dir. Joachim Trier, 2017). The author claims that these themes are similar and rooted in the same perception of the female monstrosity in both films, with different outcomes of this combination. The authors suggest that this is due to feminist tendencies becoming more prominent in every artform. However, this claim needs investigating from the feminist studies’ point of view.
