SUBSURFACE FATIGUE FRACTURE IN THE FAST-SPINNING REDUCTOR GEARWHEEL UNDER CONTACT LOADING
Authors: Nikitin I. S. , Burago N. G. , Nikitin Alexander D. , Stratula B. A.
Published: February 2023

Fatigue fracture in elements of turbo jet engine gear reduction is investigated under high angular rate loading conditions. The in-service fracture surface analysis and numerical simulations were performed for a real aircraft structure. As an example, the driven bevel gear destruction of the main gearbox central drive of the PS-90A engine is analyzed during operation. It is shown that the realized stress level in operation is close to the fatigue limit of the material. Therefore, with minor changes in the stress level of the gear, a significant range of durability can occur in the transition region between high-cycle fatigue (HCF) and very-high-cycle fatigue (VHCF). The numerical simulation is based on a multiregime model of fatigue failure developed by the authors. The application of the proposed model of fatigue failure and the implemented numerical calculation for calculating the damage function enable description of the main stages of the initiation and growth of fatigue quasi-cracks qualitatively and quantitatively during contact interaction in a rapidly rotating gearbox gear.

Published: February 2023

Mushrooms, which have been collected to meet the nutritional needs of the world for many years, have gained medical importance thanks to the bioactive compounds they produce. Thanks to studies carried out to determine mushroom diversity, the number of species identified is increasing year by year. Accordingly, in recent years, studies conducted to determine the biological activities of metabolites produced by fungi have been increasing. The present study was conducted to determine the cytotoxic, antioxidant, antibiofilm and antimicrobial activities of the seven different mushroom species (Craterellus cornucopioides, Hymenopellis radicata, Lepista nuda, Pisolithus arhizus, Ramaria flava, Schizophyllum commune, and Tricholoma ustale) collected from Tokat and Yozgat regions located in northern and central Turkey. Laboratory studies have demonstrated that mushrooms used in this study have different degrees of antibiofilm, antimicrobial, antioxidant and cytotoxic activities. At the end of the study, it is determined that C. cornucopioides and L. nuda species have the highest antimicrobial activity. In addition, mushroom species have biofilm inhibitory effects on indicator microorganisms at varying degrees ranging between 20.7 and 96.3%. As a result of antioxidant activity studies, it was determined that T. ustale has the highest free radical scavenging effect and P. arhizus, which has the highest polyphenol content, has the highest reducing power. Finally, it is determined that, among the mushrooms used in the present study, H. radicata showed higher selectivity on the MDA-MB-231 breast cancer cell line than on the normal cell line tested, while C. cornucopioides showed higher selectivity on the MCF-7 breast cancer cell line.
Data-driven evaluation of abnormal vibration of cables during typhoon In-Fa
Authors: Zhao Hanwei , Ding Youliang , Li Aiqun , Chen Bin
Published: February 2023

The input–output characteristics of cables of a long-span cable-stayed bridge in time and frequency domains were studied during the whole process of typhoon In-Fa landfall based on monitoring data. According to the signal characteristics of the time series of wind speed and direction, a new adaptive extraction method of quasi-steady wind speed and direction was developed, fusing wavelet transform and the certain-length time series averaging method. The central tendency and fluctuation about the wind speed and direction were assessed and the influences of wind and rainfall on cable abnormal vibration were analysed. Using the short-time Fourier transform, the characteristics of the evolution of vibrational energy in the time–frequency domain for abnormal cable vibration during the typhoon were reproduced. Slice analysis of the power spectrum in the frequency domain was performed at typical moments. The results of this work revealed the following. The extremely high-amplitude non-Gaussian section of abnormal cable vibrations in this typhoon event was caused by the simultaneous action of wind and rain. A high wind speed or a wind direction with low fluctuation will more likely excite high-amplitude abnormal cable vibration. Sufficient damping may help cables suppress rain-wind-induced high-amplitude vibration.
Temporary works for dismantling steel cantilever truss bridges in the USA
Authors: Miller Nathan , Zylstra Reuben
Published: February 2023

Dismantling steel cantilever truss bridges is a complex operation that requires significant engineering to produce safe and effective dismantling sequences. Such sequences often include a variety of temporary works, including temporary truss members, temporary support towers, tension-release devices and temporary attachments for heavy-lift components. This paper provides a review of the design and analysis considerations for developing a dismantling sequence for cantilever steel truss bridges and the design of the required temporary works, with three examples from the USA.
Coupling of hydraulic loading and surcharge pressure during suffusion in sandy gravels
Authors: Deng Z. , Wang G. , Jin W.
Published: February 2023

This study focuses on the coupling effect of the imposed hydraulic gradient and surcharge pressure on fine-particle loss and skeleton deformation during suffusion. A series of suffusion tests were conducted on an internally unstable sandy gravel under four different hydraulic gradients and three surcharge pressures using a large-scale high-pressure erosion apparatus. The total eroded mass, erosion rate and skeleton deformation were comparatively analysed, and the mesoscopic mechanism was discussed preliminarily. The results showed that the hydraulic gradient affected the erosion process not only in terms of the total eroded mass but also the developing pattern and duration of erosion. Surcharge pressure showed an inhibitory effect on fine-particle erosion, whereas a promoting effect on the skeleton deformation. For internally unstable soils, hydraulic gradient and surcharge pressure might have a considerable coupling effect on the fines eroded ratio and its induced strain.

Authors: Martin Renaud-Pierre , Bonnet Amandine , Renaud Jean-Claude , Chlela Robert , Toutlemonde François , Sauvaget Cyrille
Published: February 2023

Delayed ettringite formation (DEF) is strongly affected by moisture. Thus, understanding the effect of this parameter on the related degradations is of prime interest, not only for prevention strategies, but also for re-assessment of affected structures. While alkali–aggregate reactions have been extensively researched, the effect of moisture on DEF still deserves to be studied, especially for exposure conditions representative of field exposure. This paper describes an experimental programme that aims to contribute to this objective. It consists in exposing concrete specimens with different DEF potentials to controlled moisture and water supply conditions, either constant or variable. The test results with these first conditions will help to determine the relationship between moisture and expansion, while test results of variable conditions will be used to benchmark these equations. To ensure exposure conditions are as stable as possible, a specific experimental set-up was developed and is presented in this paper. Moreover, determination of the wetting–drying cycles applied to some specimens is presented and preliminary results are displayed and analysed.

Published: February 2023

It is significant to use recycled waste plastic bags in concrete to solve the issue of the disposal of leftover polyethylene in the environment. This research study incorporated the plastic bags’ polyethylene into concrete and evaluated the mechanical properties of concrete, to reduce cracking to some extent and increase the tensile and flexural strengths and deformation capacity. Six mixtures were used with varying percentages of waste plastic bags (i.e. 0, 0.3, 0.6, 0.9, 1.2 and 1.5%). The sorptivity test was conducted following ASTM C 1585 and the volume of permeable voids (VPV) test was according to the ASTM C 642 requirements. The pull-out strength of the steel rebar in a concrete cylinder was also determined. With waste polyethylene, it was noted that the flexural strength increased, pull-out bond strength declined and initial sorptivity increased. This decline in the VPV was due to the heterogeneity of the mixture, which leads to the low density of the mixture due to waste plastic bags. Experiments proved that substituting plastic bags for fine aggregates in concrete, increases flexural and split tensile strengths while decreasing compressive and pull-out strength.
Aavioghey as y Breear: Language Revitalization and the Manx Verbal System
Authors: McNulty Erin
Published: February 2023

Many minority languages across Europe and elsewhere, including in the Celtic-speaking world, underwent linguistic obsolescence in the nineteenth and twentieth centuries. In some cases, this ultimately progressed to language death. Manx, the autochthonous Goidelic Celtic language of
the Isle of Man, was one such case. In more recent times, the Manx language has seen a revival, which has increased speaker numbers. Manx represents an atypical situation among minority languages, as the present-day speaker community is, with few exceptions, made up of speakers who have had
no direct contact with traditional native speakers. Therefore, the present-day Manx speaker community bears closer resemblance to that of Cornish, as well as those of urban varieties of Irish and Scottish Gaelic, than to speaker communities in traditional Celtic language heartlands. This article
discusses the language use of speakers of Revitalized Manx. It investigates some aspects of linguistic structure in the language use of three groups of speakers who have acquired the language in different contexts: teachers of Manx, speakers who received Manx instruction through the medium
of English, and speakers who have received Manx-immersion education. An analysis of a number of verbal forms reveals differences in these three groups of Manx speakers, which may be correlated with the amount and type of input in Manx these speakers have received. The article discusses these
findings in the wider context of processes influencing the linguistic production of speakers of revitalized minority languages.

In the context of sanctions pressure and reduced access to advanced information technologies, the task of digitalizing the economy of the Russian Federation is becoming much more complicated. The task of creating a digital economy based on the transformation of sectors of the traditional economy with a high level of penetration of fundamental information technologies in order to form the processes of creating and consuming digital products is considered as the final one. The digitalization of the economy in the context of sanctions pressure should be carried out on the basis of a systematic analysis of the level of accessibility of information technologies, the degree of readiness of the socio-economic environment, and be essentially a highly accurate process. The task of building an effective digital economy in the face of sanctions pressure and limited access to key IT technologies can be formulated as a search for optimal directions for the development of traditional industries and existing macroeconomic processes based on available fundamental technologies that allow reaching the top level of the digital economy transformation hierarchy. In this regard, it is advisable to talk about the formation of a roadmap for building a digital economy, which makes it possible, under the conditions of sanctions pressure, to implement the most promising of the available segments of the digital economy. A key element of such a mechanism should be end-to-end systemic monitoring of the level of development of the digital economy and digitalization processes. Particular attention should be paid to assessing the economic consequences of digital transformation.
Communicative Psychosemantics of Cognitive-Noetic Development of the Personality
Authors:   Tomsk State University (Tomsk, Russian Federation), Kabrin Valery I.
Published: February 2023

A comprehensive analysis and description was conducted of communicative psychosemantics as a universal basis for constructing a structural-dynamic model of the cognitive-noetic potential for the development of a professional personality in the modern educational process. The study used the main humanities communicative sense-forming processes of qualitative methods: hermeneutics, phenomenology, content analysis and experimental psychosemantics. It was found that the relevance of these methods depends on if they take into account authentic communicative factors. For hermeneutic understanding, these are universal factors of contradictions in the communicative situation due to the doubling of mismatched expectations and ideas among partners: on the one hand, about the subject and their linguistic representations; on the other hand, about each other and how each portrays themself. For phenomenological immersion in directly conscious experiences, this is a communicative moment of meeting with the other, the unknown, which gives rise to an ambivalent stress-transformation. It is they who actualize the intuitive-creative cycle of peak experiences: catharsis - imprinting -ecstasy - insight. Content analysis takes into account specific communicative contexts, but needs psychosemantic contextual markers. We created “Communicative psychosemantics” to integrate all high-quality meaning-oriented research methods based on the sociability of the mental and spiritual life of a person in line with the structural-dynamic model of the cognitive-noetic potential of personality development. The intentional dynamic vector of the model is presented as a cumulative cycle of integration of qualitative psychological modalities: motivation - perception - imagination - emotion. The transcendental structural-level vector of communicative psychosemantics is represented by holarchic levels: value-semantic formations - problematic conceptual target solutions - constructive compositional objectivism -archetypal symbolic expressive incarnations. This structural-dynamic model of communicative psychosemantics is translated into an equivalent model of 16 basic positional strategies of the educational process, focused on the cognitive-noetic development of a person's professional and personal potential.
Unnamed procedural actions in Russian civil proceedings
Authors:   South Ural State University, Alekseev Andrey A.
Published: February 2023

The article formulates the content of the concept of "unnamed procedural action", as well as the conditions and limits of its application in modern civil proceedings in Russia. The complexity of understanding this phenomenon is due to the presence of a logical contradiction, which manifests itself in the following. On the one hand, the legislator considers permissible only those procedural actions, the list and order of which are legally fixed. On the other hand, the rapid development of public relations increasingly requires participants in the civil process to go beyond the prescriptions existing in the law. This state of affairs suggests that all procedural actions can be divided into two main groups. The first of them is the named procedural actions (procedural actions and the procedure for their commission are provided for in the law). The second is unnamed procedural actions (procedural actions and (or) the procedure for their commission are not provided for by law). We believe that unnamed procedural actions should be considered through the prism of such categories as "legal conduct", "judicial discretion" and "unnamed legal action", the latter of which has been studied in sufficient detail in the theory of civil law. Unnamed legal actions are also present in the theory of criminal procedure, but here they are usually referred to as "other procedural actions". In the theory of civil procedure, there is no mention of the term "unnamed procedural actions" or its analogues. There are no specified categories in the legislation. The conducted research allowed us to draw the following conclusions. All actions committed in the civil process, including those not named, can be considered as part of legal behavior, which is characterized by: 1) Normativity; 2) State control; 3) The presence of legal consequences. In relation to unnamed procedural actions, these signs, especially normativity, receive a slightly different, often broader, content. Nevertheless, if a number of conditions are met, the existence and possibility of their commission in modern civil proceedings is beyond doubt. Thus, we believe that an unnamed procedural action can be defined as a legally fixed or legally determined active behavior of participants in civil proceedings, implemented within the framework of initiated civil proceedings, entailing legal consequences and aimed at timely and correct consideration and resolution of a civil case. The author declares no conflicts of interests.

The establishment and development of an effective probation system in the Russian Federation provides for the assignment to penal inspectorates of appropriate powers: assistance in matters of employment, housing, psychological and legal support to persons - primarily those released from serving the sentence and those serving non-custodial sentences. With regard to criminal procedural activity, it is possible to single out norms, enshrined in criminal and criminal procedural legislation, that can be called harbingers of conciliation procedures in the Russian criminal process. These are norms providing for: the possibility of reconciliation between the victim and the accused; exemption from criminal liability; termination of the criminal case due to reconciliation with the victim; and norms applied in criminal proceedings against minors and providing for release in connection with the application of coercive measures of educational influence. A number of norms of the Criminal Procedure Code of the Russian Federation directly provide for the need to explain to the parties the right to reconciliation. The author sees some of the characteristics inherent in conciliation procedures in the fast-track forms of investigation: recognition by the suspect of their guilt, the nature and extent of the harm caused by the crime, agreement with the legal wording of the act; consent of the victim to the use of fast-track investigation procedures. The author stresses that, in criminal proceedings and for the purposes of criminal proceedings, the probation service cannot use mediation technologies: this is interference in a different area. It seems that attempts to “introduce” the probation service directly into crimes investigation or litigation are groundless and inappropriate. At the same time, researchers of this issue note the positive effect of using mediation technologies in working with convicts in penal activities. Mediators assist penal inspectors in working with juvenile offenders and their families. Their job is to advise on resolving conflicts and interpersonal problems, help build relationships with relatives, and teach socially beneficial interaction skills.
Specificity of causal connection in criminal complicity
Authors:   Kuzbass Institute of the Federal Penitentiary Service of Russia, Shesler Aleksandr V.
Published: February 2023

The article discusses causality in criminal complicity characterised by causal connection between the common deed and common criminal result of accomplices as well as its objective-subjective and natural character. The author argues with those who believe that criminal complicity manifests two types of relations between the actions of accomplices and their common criminal result: causal or conditioning. The author criticizes the idea that causal connections in criminal complicity is exclusively objective by nature and links the act with inevitable consequences. According to the author, such a connection as a manifestation of social determination is objective-subjective, and the consequences of the common deed of accomplices are not only inevitable, but also possible.
On the substitution of compulsory and corrective labour with penal labour due to malicious evasion
Authors:   Tomsk State University, Isakov Vladislav S.
Published: February 2023

When the Criminal Code of the Russian Federation included penal labour as a form of punishment, the legislative framework governing the appointment and execution of this criminal punishment was updated. This brought about an objective need to study the procedure of substituting other punishments, not related to the isolation of the convict from society, with penal labour. Based on legal acts and research, the author raises the question whether it is admissible to substitute compulsory and corrective labour with penal labour according to Part 3 of Art. 49 and Part 4 of Art. 50 of the Criminal Code of the Russian Federation, respectively, if the malicious evasion from serving the previous sentence concerns the convict's violation of labour discipline. Some researchers believe that when substituting the unserved part of compulsory or corrective labour with a more severe criminal punishment, the court should not take into account the nature of malicious evasion. However, certain types of violations of the procedure and conditions for serving compulsory and corrective labour under Art. 30 and Art. 46 of the Penal Code of the Russian Federation testify to the inability of the convict to carry out labour activities, which is an integral attribute of penal labour. Therefore, the court needs to consider substituting the unserved part of compulsory or corrective labour with confinement, which will spare the necessity of returning to this issue when the convict is found to be maliciously evading compulsory labour. Currently, there is no uniform judicial practice on the problem under study. The failure to fulfill or improper fulfillment of the labour duties by the convict may be a reason for substituting compulsory or corrective labour with both penal labour and imprisonment, since the court is not required to justify the choice of punishment in the form of penal labour or confinement when a case under Part 3 of Art. 49 and Part 4 of Art. 50 of the Criminal Code of the Russian Federation is being considered. The author proposes to amend Decree No. 21 of the Plenum of the Supreme Court of the Russian Federation of December 20, 2011, “On the application by courts of legislation on the execution of sentences”, according to which the systematic violation of labour discipline by the convict while serving compulsory or corrective labour becomes the basis for the substitution of the unserved part of the punishment with penal labour. The proposed changes not only comply with the norms of international law, but also make it possible to exclude the use of penal labour in relation to convicts avoid labour activity.

Published: February 2023

In response to the significant public health threat caused by coronavirus disease (COVID-19), real-time surveillance, containment, and mitigation measures were implemented in the Federation of Bosnia and Herzegovina (FBiH). Our objective was to describe the surveillance methodology, response measures, and epidemiology of COVID-19 cases in FBiH from March 2020 to March 2022. The surveillance system implemented across FBiH enabled health authorities and the population to monitor the development of the epidemiological situation, the daily number of reported cases, as well as basic epidemiological characteristics and geographic distribution of cases. As of 31 March 2022, 249,495 cases of COVID-19, and a total of 8,845 deaths were recorded in FBiH. Upkeeping of real-time surveillance, maintaining non-pharmaceutical interventions, and speeding up the vaccination roll-out were paramount for controlling COVID-19 in FBiH.
Electrodermal activity and heart rate variability for detection of peripheral abnormalities in type 2 diabetes: A review
Authors: Žnidarič Matej , Škrinjar Dominik , Kapel Alen
Published: February 2023

Modern medicine exhibits an upward trend towards non-invasive methods for early detection of disease and long-term monitoring of patients’ health. Diabetes mellitus and its complications are a promising area for implementation of new medical diagnostic devices. One of the most serious complications of diabetes is diabetic foot ulcer. The main causes responsible for diabetic foot ulcer are ischemia caused by peripheral artery disease and diabetic neuropathy caused by polyol pathway-induced oxidative stress. Autonomic neuropathy impairs function of sweat glands, which can be measured by electrodermal activity. On the other hand, autonomic neuropathy leads to changes in heart rate variability, which is used to assess autonomic regulation of the sinoatrial node. Both methods are enough sensitive to detect pathological changes caused by autonomic neuropathy and are promising screening methods for early diagnosis of diabetic neuropathy, which could prevent the onset of diabetic ulcer.

An Economic Evaluation of the European Union’s 2030 Climate Policy Plan
Authors:   People&Global Business Association, Sadler Thomas R.
Published: February 2023

Purpose: The purpose of the study is to evaluate the European Union’s “Fit for 55” plan, announced in 2021, which intends to meet a 2030 goal of reducing carbon emissions by 55 percent from 1990 levels.
Design/methodology/approach: An analytical model is used to assess the impact of the EU environmental policies, including the carbon border tax, emissions trading system, energy efficiency, and emission standards.
Findings: The study finds that the environmental policies achieve different policy criteria, including cost minimization, equalization of marginal abatement cost, minimization of general equilibrium cost, political feasibility, and minimization of inequitable impacts across income groups. But no single policy instrument is necessarily superior to the others. The paper finds that a revenue-neutral carbon border tax and an emissions trading system with auctioned permits satisfy the most evaluation criteria.
Research limitations/implications: For the purpose of simplification, the model ignores dynamic extensions. That is, the adjustments of businesses to policy measures and the effects on emissions are beyond the scope of this analysis.
Originality/value: The study develops a model that evaluates the European Union’s environmental policies in a unifying perspective, assessing the tradeoffs of policy design.
La determinación existencial del conocimiento artístico: elementos para su sistematización y análisis reflexivo.

Published: February 2023

Este artículo toma como base el modo sociológico de analizar el conocimiento científico, orientándolo al estudio de la determinación existencial del saber artístico, esto es, del agenciamiento social de su producción, distribución y consumo. Nuestro propósito es evidenciar que la razón artística es producto de sujetos colectivos, empíricos e históricamente situados. Se presenta así un proceso ordenado de abstracción y aproximación al complejo terreno de las tribus y los territorios disciplinares del conocimiento artístico y su investigación, lo que posibilita una visión más profunda y reflexiva de la realidad social de su constitución.

La perspectiva la marca una aproximación sistémica a las formas institucionales de poder que actúan en la constitución socio-histórica del conocimiento artístico y que desarrollan mecanismos de dominación en el presente. Una cartografía crítica en la que situarnos, para así trazar un conocimiento de segundo orden, siempre ligado a la capacidad de pensar nuestro pensar sobre el arte y la realidad práctica desde la que se construye y se sitúa: subjetiva, epistemológica y socialmente. Nuestra meta es apelar al papel reflexivo que la subjetividad debe desempeñar en la construcción dinámica y situada del saber artístico desde una identidad pedagógica como la investigadora.
Selfies and Speeches of a President at War: Volodymyr Zelensky’s Strategy of Spectacularization on Instagram
Authors: Plazas-Olmedo Maite , López-Rabadán Pablo
Published: February 2023

The spectacularization of politics is not the exclusive patrimony of the media in their news coverage. Leaders from all over the world have successfully incorporated this “communicative style” into their own strategies, a style that finds a suitable space in visual social networks such as Instagram, in dynamic formats such as video, and in crisis contexts. This article analyzes the “spectacularization” of Ukrainian President Volodymyr Zelensky’s through Instagram. The methodological proposal is based on the study of the 5W in relation to the digital image and investigates the leading role, the staging, the space, and the technical resources of the videos. Thus, a content analysis is applied to a sample of 143 videos published by the president on his official profile in February–March 2022, when the conflict between Russia and Ukraine began, and in September–October 2022. We observed that Zelensky uses video in an intense and “spectacular” way: He exploits his figure in a professional style, strategically combines careful staging with amateurism, and uses resources such as subtitles to internationalize his discourse.
Assessment of HLA-DRB1 alleles frequencies in patients with pemphigus in Russian population
Authors: Olisova Olga Yu. , Shimanovskiy Nikolai L. , Dukhanin Alexander S. , Teplyuk Natalia P. , Lepekhova Anfisa A.
Published: February 2023

BACKGROUND: Pemphigus vulgaris is known to be associated with genetics, immunological and hormonal factors which cause acantholysis resulting in intraepidermal blistering. Moreover, Human class II leukocyte antigen (HLA) alleles are known to be the best-established predisposing factor for its development. Class II HLA alleles vary among racial/ethnic backgrounds.
AIM: we investigated an association between HLA class II DRB1 alleles and pemphigus vulgaris among the Russian population.
MATERIALS AND METHODS: A total of 70 patients with confirmed diagnosis of pemphigus vulgaris were genotyped for HLA class II alleles. HLA class II frequencies were compared with healthy volunteers (n=92). The statistical significance of differences between patients and controls was evaluated using Fishers exact test. A single blood sample for HLA typing was obtained from all the subjects. The strength of association between HLA alleles and pemphigus vulgaris was estimated by odds ratio (OR) and 95% confidence intervals (CIs) p 0.01 was considered to be statistically significant. P-values were corrected for multiple comparisons according to the BenjaminiHochberg method.
RESULTS: We observed that DRB1*4 and DRB1*14 allelic groups were associated with pemphigus vulgaris (41.4% vs 8.7%; OR 2.33 vs 0.34; p=0.000001 and 27.1% vs 6.5%; OR 1.98 vs 0.41; p=0.0004 respectively), while HLA-DRB1*11 and HLA-DRB*15 were negatively associated with pemphigus vulgaris (4.3% vs 21.7%; OR 0.33 vs 1.62; p=0.001 and 5.7% vs 19.6%; OR 0.44 vs 1.5 respectively).
CONCLUSIONS: Our findings suggest, that HLA DRB1*4 and DRB1*14 alleles are genetic markers for pemphigus vulgaris susceptibility, whereas DRB1*11 and HLA-DRB*15 groups appear protective in Russian population.
Urticarial vasculitis in patients with chronic hepatitis C virus as an interdisciplinary problem
Authors: Teplyakova Kseniya S.
Published: February 2023

Urticarial vasculitis is a skin disease characterized by recurrent urticarial lesions and histological features of leukocytoclastic vasculitis. Urticarial vasculitis is known to occur in the association with various infectious diseases, including chronic hepatitis C virus. However, the clinical features of urticarial vasculitis associated with hepatitis C virus have not been systematically characterized, which complicates the management of these patients.
This review presents an analysis of published clinical, histological and laboratory findings in patients with urticarial vasculitis in the association with chronic hepatitis C virus, which can be helpful for early diagnosis and optimization of the patient management.
We performed a Pubmed search to identify clinical cases from 1971 to 2022 using the keywords "urticarial vasculitis", "hepatitis C virus infection". According to the inclusion/exclusion criteria, 13 clinical cases of urticarial vasculitis associated with hepatitis C virus were included in the analysis.
Clinical manifestations were urticarial rashes (n=13), associated with residual hyperpigmentation in 8 patients, tenderness/burning ― in 7 patients, and a lesion duration (24 hours) ― in five patients. Arthralgias were described in 3 patients.
On histological examination, there were fibrinoid necrosis (n=2); leukocytoclasia (n=4); erythrocyte extravasation (n=1); dermis edema (n=2); perivascular infiltrate consisting of neutrophils (n=5), eosinophils (n=4), lymphocytes (n=3), and histiocytes (n=2). Hypocomplementemia was reported in eight patients. The laboratory work revealed cryoglobulinemia (n=9) and positive rheumatoid factor (n=6), which were the characteristic findings in the association of these diseases.
The association of urticarial vasculitis and chronic hepatitis C virus is an important interdisciplinary problem that requires an interaction of dermatologists, allergists, hepatologists, rheumatologists and infectious disease doctors. Histological examination is indicated to differentiate between urticaria and urticarial vasculitis in patients with atypical urticarial lesions. Early detection of chronic hepatitis C virus is necessary for the timely administration of antiviral therapy. The urticarial vasculitis treatment should be selected taking into account their efficacy and the risk of hepatotoxicity.
Difficulties in diagnosing ALK-negative anaplastic large cell lymphoma manifesting from a skin lesion

Anaplastic large cell lymphoma is a rare form of non-Hodgkin's lymphoma that requires an early diagnosis and urgent therapy due to aggressive tumor process. Clinically, most non-Hodgkin's lymphoma present with lymphoadenopathy and В-symptoms (such as weakness, drowsiness, fatigue, subfebrile fever, profuse night sweats). However, anaplastic large cell lymphoma may present with nonspecific skin lesions with minimal or no B-symptoms. The skin lesions are heterogeneous, which may also delay verification of the diagnosis.
We present a case of widespread anaplastic large cell lymphoma skin lesions mimicking a case of erysipelas, which progressed rapidly from a single rash on the wrist to an extensive lesion of the right breast within 1 month. Prior to verification of the diagnosis, the patient was treated for erysipelas, pyoderma, and herpes zoster with no response to therapy. Immunohistochemical examination of a skin biopsy confirmed the diagnosis of ALK-negative anaplastic large cell lymphoma. At the time of publication, the patient had completed 1 course of the CHOEP regimen, and 6 cycles of the program were planned.
Our case demonstrates the necessity of a broad differential diagnosis of rashes torpid to the current therapy.

The objective was to analyze experimental animal models of osteonecrosis (ON) using the femoral head, show advantages and disadvantages, capacity to translate the findings for adult and pediatric orthopaedics, potential model modifications for orthopaedic and rheumatology research. Material and methods The original literature search was conducted on key resources including PubMed, Web of Science, Cochrane Library, E-library, and the Springer databank. Literature searches included Russian, English, and Italian studies. The research covered studies of 1980 to 2021 and included important landmarks of laboratory experiments with animal models. Results and discussion Although there was no ON model with ideal conditions found for it, the choice of a model could be based on the researcher’s goal reproducing ON as a type of “osteochondropathy” to explore the results applicable to pediatric orthopaedics or classical ON in adults. Animals with long-term open growth plates, intensive blood circulation in the bone and rapid regeneration being characteristic of juvenile models of rats, rabbits and pigs could be appropriate for the experiment. Dogs, sheep, pigs and emus, in particular, were practical for reproducing ON in adults. Non-traumatic models of ON in adults were reversible and consistent with early stages of the condition. Conclusion The need for ON simulation increased due to progressing orthobiological techniques (PRP‑therapy, BMCs technologies, etc.) in the treatment of ON. Application of orthobiological treatment resulted in heterogeneous, scattered outcomes being statistically unreliable and necessitating the search for optimal animal models and assessment of treatment methods for ON in modern orthopaedics.

Introduction The low detection rate of osteoporosis and the lack of treatment in the elderly can contribute to a higher rate of low-energy fractures, poor results of surgical treatment and mortality. The purpose of the work was to evaluate the frequency of detection and treatment of osteoporosis before the fracture and during specialized trauma and orthopaedic care provided for a low-energy fracture of the proximal femur in the elderly. Material and methods A retrospective analysis of 209 medical histories of individuals aged 60 years and older who received treatment for a low-energy fracture of the proximal femur in 2 randomly selected trauma departments and a telephone survey of the patients performed at 3-8 months were produced. Availability of the diagnosed osteoporosis and the treatment before and during fracture repair were identified. Results The diagnosed osteoporosis was established in 5.2 % prior to fracture occurrence and in 16.7 % after the fracture occurrence. In both cases, the condition was treated with colcalciferol, calcium and pathogenetic therapy used in some cases. Discussion Diagnosis and treatment of osteoporosis in the elderly remained low before a lowenergy fracture of the proximal femur and during trauma and orthopaedic treatment. Conclusion The initiation and treatment of osteoporosis during the trauma and orthopaedic management of a low-energy fracture should be considered as a component of the high-quality specialized care.

There is a paucity of Russian medical literature reporting lumbosacral transitional vertebrae in children and adolescents. Many important aspects of the condition including two nosologies of sacralization of the L5 vertebrae and lumbalization of the S1 vertebrae have been under-explored. The objective was to establish overall frequency and frequency of certain types of lumbosacral transitional vertebrae in children and adolescents who sustained a lumbar injury and to investigate clinical manifestations of the pathology. Material and methods A comprehensive examination of 312children aged 7 to 18 years who suffered a lumbar injury was performed. Lumbosacral transitional vertebrae was radiologically diagnosed in 19 (6.09 %) subjects. Grading system of A.E. Castellvi et al. (1984) was used to classify the pathology. Results From 19 patients with lumbosacral transitional vertebrae, sacralization of the L5 vertebrae was detected in 16 (84.21 %) individuals. Lumbalization of the S1 vertebrae was diagnosed in 3 (15.79 %) children. Type II (n = 13) and subtype "b" (n = 10) were most common. No types III and IV of the disease were seen. No clinical symptoms indicating the likelihood of having lumbosacral transitional vertebrae were observed in the patients prior to the lumbar injury. Conclusion The frequency of occurrence of lumbosacral transitional vertebrae and its structure were reviewed in children and adolescents. The patients demonstrated no clinical manifestations of the condition before the children sustained lumbar injuries. Various aspects of transitional lumbar vertebrae in children and adolescents require further study.
