Albania’s Foreign Economic Relations, 1956–1977: Between Moscow and Beijing
Authors: Dzhalilov Teimur A. ,   Institute of World History of the RAS, Moscow
Published: July 2024

This article analyses the economic relations of the People’s Republic of Albania with socialist countries in the late 1950s–1970s, as well as the Soviet Union’s strategy of using the “economic factor” in its relations with Albania. The main sources for the article were documents of the embassies of the USSR in socialist countries, information notes of Soviet economists, reports of special services and analytical materials compiled in the Central Committee of the CPSU. The author concludes that both the Soviet Union and China sought to use economic cooperation with Albania to draw it into the orbit of their international policies. To this end, Moscow and Beijing developed complex strategies of foreign economic relations, which included interstate cooperation and partnership within the framework of international socialist cooperation of the economies of the people’s democracies. The amount of economic aid received by the PRA was significant and allowed the country to enter the stage of industrial development. At the same time, both the Soviet and Chinese partners tried to contain the gigantomania of their ally’s plans by reducing loans to certain obviously unprofitable enterprises. The Albanian elite, however, could not admit the fallacy of its economic policy and therefore attributed its low effectiveness to external enemies. Neither the Soviet Union nor the People’s Republic of China managed to use the “economic factor” to influence the internal politics of the PRA for a long period of time. Skillfully maneuvering between Moscow and Beijing and playing on the contradictions of the two leading powers of the world socialist system, Tirana maintained its socio-economic model, which proved surprisingly stable.
“Ab Hoc Dispersione Nomen Rossicum”: G. S. Bayer’s Etymological Quest in the Context of the Scholarly Tradition
Authors: Sokolov Sergei V. ,   Ural Federal University, Ekaterinburg, Goryaev Sergey O. ,   Ural Federal University, Ekaterinburg, Russia
Published: July 2024

This article examines the ideas on the origin of the name Rus (Russian: русь) formulated by Gottlieb Siegfried Bayer (1694–1738), a professor at the St Petersburg Academy of Sciences. Bayer expressed his observations in an unfinished Latin text published after his death in the journal of the Academy. Using this publication, which has never been translated into Russian, the authors of the article examine Bayer’s critical comments and objections to various versions of the origin of the name Rus. Bayer’s text is a kind of catalogue of hypotheses that existed in the academic world in the first half of the eighteenth century. From the point of view of modern scholarship, all of them can be regarded as naive folk etymologies or legends (for example, the creation of the name Rus from the ancient name of a river, its comparison with the biblical people of Rosch, or the appeal to the legend of the brothers Lech, Czech and Rus, etc.). These versions are subjected to a fair and ironic criticism by Bayer. Based on new research on ideas of ethnic nomination, the authors place the versions in the context of discussions in historical writings of the sixteenth–eighteenth centuries. The results of the analysis of Bayer’s arguments show that he often makes very good use of his knowledge of ancient and modern languages and of the historical context to criticise other people’s versions. The article also examines in detail the etymology to which Bayer himself adheres. According to Bayer, the name of the Russian people comes from the Slavic word рассеяние (“dispersion”). This etymology was proposed in the sixteenth century by the Austrian diplomat Siegmund von Herberstein and supported by some Polish and German scholars. The authors show that Bayer finds additional historical and linguistic arguments for this hypothesis, which, of course, do not withstand the criticism of contemporary scholarship. The article notes the influence of Bayer’s hypothesis on the ideas of G. F. Mьller. The authors suppose that a certain forgetfulness of Bayer’s hypothesis is due to the fact that it contradicts his reputation as a “Normanist”.
Ideological Campaign or a Fatal Accident? The Discussions of 1928–1930 and the Collapse of Historian M. I. Yavorsky’s Career
Authors: Lazarev Yakov A. ,   Institute of Russian History of the RAS, Moscow,   Ural Federal University, Ekaterinburg
Published: July 2024

This article examines the personality of Matvei Ivanovich Yavorsky, a leading Ukrainian Marxist historian of the 1920s. The article reveals the circumstances that led to the historian’s removal from leading academic positions in the early 1930s. The historiography created an image of Yavorsky as a scholar who suffered under the attacks of Moscow Marxist historians led by M. N. Pokrovsky and his disciple P. O. Gorin. Contrary to popular belief, the author shows that the story of Yavorsky’s downfall was a series of coincidences that led to the transformation of an ideological polemic into a campaign of harassment, followed by his arrest and death. The article explains why the debates of the time were not the cause of Yavorsky’s downfall. Patronage from the Ukrainian party leadership allowed Yavorsky to engage in aggressive polemics with his opponents (primarily Gorin). Discussions within the Ukrainian academic community led to a softening of Yavorsky’s position on conceptual differences (the driving forces of the revolution in Ukraine) rather than a public campaign against him. The author shows that Gorin and Pokrovsky did not have the administrative capacity to start harassing the scholar. The collapse of Yavorsky’s career turned out to be the result of the revealed facts of his biography (service in the Austro-Hungarian army). Yavorsky’s situation did not fit into any of the ideological campaigns of the time and came as a complete surprise to the local party leadership. Attempts to launch a campaign against Yavorsky (“yavorshchina”) were quashed by the Ukrainian SSR leadership, which gave the historian the opportunity to move to Leningrad. There, however, he was caught by the OGPU’s Operation Spring. During the investigation in Ukraine, people who had testified against Yavorsky were implicated in the case. This led to his arrest, imprisonment and death sentence.
“We must study and honour the scholars who... brought Russian scholarship to the forefront”: N. S. Lebedev’s Defence of the Thesis on V. G. Vasilievsky in 1943
Authors: Skvortsov Artyom M. ,   S. I. Vavilov Institute for the History of Science and Technology of the Russian Academy of Sciences (St Petersburg Branch),   St Petersburg State Pediatric Medical University, St Petersburg
Published: July 2024

The focus of this article is N. S. Lebedev’s dissertation (1943) entitled “V. G. Vasilevsky as a Byzantine Scholar”, which was carried out by the evacuated Leningrad branch of the Institute of History of the Academy of Sciences in Tashkent. The author refers to the transcript of the meeting of the Academic Council, Lebedev’s biographical materials kept for his thesis (RAS archive), and his publications. As early as the late 1930s, Lebedev had intended to write a thesis on Byzantium and the Mongols, but the inaccessibility of sources and literature during the Great Patriotic War changed these plans. In the end, a historiographical topic was chosen. Given the scarcity of such studies, a research programme had to be developed. Lebedev did not limit himself to outlining the main conclusions of the central figure of his thesis but sought to analyse the factors of Vasilievsky’s formation as a scholar and the conditions of the emergence of Byzantine studies in Russia. He also assessed the merits and shortcomings of the pre-revolutionary scholar’s work. The opponents who spoke at the debate, namely, V. I. Picheta, S. K. Bogoyavlensky and E. A. Kosminsky, emphasised the importance of the “political moment” of the defence of the thesis and the significance of Vasilievsky for national and world scholarship, paying less attention to the characteristics of Lebedev’s work. The historian’s conclusions indicate a desire to demonstrate the leadership of Vasilievsky and Russian scholarship in the study of Byzantine history. The research thus served an important ideological function, i. e. to demonstrate the achievements of Russian scholars. By updating the pre-revolutionary legacy, the debate serves as a certain marker of the revival of Byzantine studies in Russia, which began in the late 1930s and entered their active phase in 1943.
Genesis and Metamorphoses of the Soviet Ritual Canon of Commemoration of the Dead Participants of the Great Patriotic War (1940s–1960s)
Authors: Popov Aleksei D. ,   V. I. Vernadsky Crimean Federal University, Simferopol,   Tyumen State University,Tyumen
Published: July 2024

This article examines the emergence and subsequent development of ritual and memorial practices related to the commemoration of the dead participants in the Great Patriotic War in the USSR in the 1940s–1960s. The author demonstrates that the military ceremony that developed in 1941–1945 had a significant impact on the development of postwar commemorational rituals conducted by civilians near memorial buildings (guard of honour, pronouncing an oath, mourning salute). Further, the author considers the memorial innovations of the period of 1957–1968, which he calls “axial age,” when a memorial canon which practically did not change throughout the late Soviet period formed and is still relevant; it included the cult of the Unknown Soldier, the cult of Eternal Flame, and Komsomol-pioneer posts No. 1, etc. Their appearance in Soviet realities and subsequent distribution was due to a combination of many internal and external factors, and the coincidence of the efforts of various actors — from the top officials of the state to ideological lower-level workers and teachers. Individual ritual forms could be borrowed from abroad but transformed and adapted to Soviet memorial culture. Reflecting on the popular concept of “inventing traditions” by E. Hobsbawm and based on the examples he analysed, the author shows that the possibilities of inventing rituals “from scratch” are very limited. In fact, there is a process of creative construction, considering the practices, scenarios, material, and symbolic objects already existing in national or foreign memorial culture. There is also the effect of “ritual synergy” when the spread of some rituals creates conditions for the appearance and development of others.

Oropouche virus (OROV) is an arbovirus transmitted to humans by mosquitoes, with the Culicoides paraensis mosquito species as its primary vector, causing Oropouche fever. Records of an outbreak in Brazil have so far been restricted to Central-North region of the country. However, an increase in the occurrence of cases of this disease has been observed in the state of Bahia, where the rapid spread of the OROV virus is configured as an outbreak in the South and East macro-regions of great concern for public health. This is a case-based study of acute OROV infection that led to the death of two young women without comorbidities amid an outbreak of the disease. The patient’s biological samples were subjected to routine real-time PCR assays for the diagnosis of Oropouche fever and other pathologies. In addition, serological tests and metagenomics were performed during the laboratory investigation. This study shows the need for an active and efficient surveillance system to control the spread of this virus, as well as the importance of carrying out prospective studies to better clarify the natural history of this disease.
POTENCIAL DO ROMANCE GRÁFICO "PÍLULAS AZUIS" EM DESMISTIFICAR ESTIGMAS SOBRE HIV ATRAVÉS DOS CONTEÚDOS CURRICULARES
Authors: Moraes Vinícius dos Santos , Araujo-Jorge Tania Crominini , Ferreira Roberto Rodrigues
Published: July 2024

Apesar dos avanços em políticas públicas e atendimento à saúde, estima-se que no Brasil mais de 1 milhão de pessoas vivam com o vírus da imunodeficiência humana (HIV). A educação em saúde é um importante processo de profilaxia que pode contribuir na disseminação de informações que atenuam o aumento de casos. Dentre as diferentes estratégias utilizadas nos processos educativos, os produtos imagéticos são fortemente aliados devido ao seu grande potencial de comunicação. O objetivo deste trabalho foi analisar o Romance Gráfico (RG) Pílulas Azuis a fim de identificar seu potencial para abordagem sobre o HIV no ensino de ciências e biologia. Pílulas Azuis é um RG autobiográfico de Frederik Peeters que apresenta seus desafios e angústias ao descobrir que sua namorada Cati e seu filho são soropositivos. Realizamos Análise de Conteúdo na obra demonstrando os elementos imagéticos e textuais que podem possibilitar seu uso no ensino. Após a análise, identificamos 67 trechos com abordagens relacionadas ao tema alvo da pesquisa. Os trechos foram organizados em 5 categorias: “preconceitos e estigmas”, “Cuidado e tratamento”, “Transmissão e reprodução do vírus”, “Impactos emocionais e psicológicos” e “Visão social da Ciência”. Peeters consegue em sua obra trazer o HIV de forma empática e com fácil compreensão, contextualizando ao leitor temas complexos e reprimidos na sociedade. Assim, identificamos que o material apresenta potencial de utilização no ensino, apesar das restrições existentes na BNCC, assim como trazer para o debate questões sociais pertinentes ao cotidiano de pessoas soropositivas, desmistificando estigmas presentes no imaginário coletivo.
Conciencia histórica: interacción entre emociones y cogniciones en un paro estudiantil
Authors: Latapi Escalante Paulina
Published: July 2024

El estado de la cuestión sobre movimientos estudiantiles mexicanos recientes reportó la ausencia de estudios que conjugaran la perspectiva historiográfica con la educativa. Objetivo: analizar un paro estudiantil en relación con la conciencia histórica y las cogniciones-emociones. Metodología: etnografía educativa, según el enfoque de Rockwell (memoria interpretativa), complementada con la Teoría Fundamentada en la vertiente de Charmaz (subjetivación). Se analizaron narrativas orales (8), escritas (19), y visuales (23), del estudiantado parista de la Facultad de Filosofía de la Universidad Autónoma de Querétaro (UAQ), México. Resultados: las cogniciones preponderantes identificadas fueron: concebirse como sujetos históricos en el devenir de las luchas estudiantiles y con identidades individuales y colectivas transformadas por el paro. Las emociones y sentimientos preponderantes fueron: miedo, inseguridad, decepción, sentido de hermandad e incertidumbre, que fungieron como engranajes de los pensamientos y como motores de las acciones. Conclusiones: la conciencia histórica se desarrolló fuera de las aulas, la concepción del tiempo fue comparativa, desde el presente se miró al pasado y se reparó en un futuro posible, lo cual transformó las identidades individuales y colectivas. De lo anterior, deriva la necesidad de realizar investigaciones sobre emocionalidad en la enseñanza de la historia como orientadora de acciones.

Un Indicator values for food shelf life prediction: A review
Authors: Espinoza Tellez Teofilo Macario , Quevedo-León Roberto , Diaz-Carrasco Oscar
Published: July 2024

The short time that people have to cook their own food has led industries to satisfy the need for ready-to-eat products. This has motivated a progressive increase in studies that can determine the time at which the product can be safely consumed (shelf life). There are several methods for determining the shelf life of products; but regardless of the method used, the key is to know the minimum and/or maximum values of the indicators that define their deterioration. These values of spoilage indicators can change according to the compositional conditions of the food or the conditions under which it is stored during its shelf life. This review provides values for indicators used in tests for the determination of food shelf life, according to their nature, and environmental conditions, as way to be used by researchers as a reference in their predictions. The results of this research show scientific evidence through published articles about indicator values, their changes, referring to food shelf life kinetics. These values can be used for the prediction of food shelf life, for comparison purposes with their respective studies. It will be of importance for consumers, who will be able to use these values as a reference in the storage of these products. Shelf life indicator values for foods not considered in this work should be evaluated or experimented with in future work.

Published: July 2024

Evaluation of coronary artery blood flow using transesophageal echocardiography is a very useful noninvasive and rapid test, although there are some problems such as technical differences between examiners and angle dependency of blood flow evaluation. In coronary artery bypass surgery, it is useful to determine the degree of preoperative coronary artery stenosis and to evaluate grafts, and in Bentall surgery, it is useful to confirm that no medically induced coronary artery stenosis caused by coronary artery reconstruction has occurred. Further studies will be conducted to improve the accuracy and usefulness of this method.

Published: July 2024

LaFeO3 (LFO) material has been widely used as a gas sensor construction material. Although LFO has been widely applied to gas sensors, the selectivity and sensitivity as well as the working temperature of gas sensors are still not optimal. In this study, the LFO was Co-doped and coated with single layer rGO to analyze its sensitivity and selectivity based on adsorption energy using Density Functional Theory (DFT). Based on this research, it was found that the presence of Co doping and rGO coating could increase the adsorption energy on the LFO. The addition of the rGO layer to the LFO increased the adsorption energy by 23.58% from -2.38 eV for Co-doped LFO to -2.93 eV when rGO was added. This shows the potential of adding rGO layers to LFO materials for sensor materials.

Published: July 2024

Tropical weather prevails in the Pangkalpinang city region, complemented with a changeable rainy season that experiences monthly variations. This phenomena results in a considerable amount of precipitation in the city of Pangkalpinang, making the area known for its extreme rainfall. Using multiple linear regression approaches to anticipate monthly precipitation is the aim of this work. Rainfall (RR), air temperature (T), air humidity (RH), and air pressure are all part of the dataset that was collected over an 11-year period (2011–2021). The information was obtained from the meteorological station in Depati Amir Pangkalpinang. This study uses the multiple linear regression method. The rainfall forecast results are compared to the observed actual rainfall amounts. Based on air temperature and air humidity as predictors, the results show that the estimation of cumulative monthly precipitation in the Pangkalpinang city region for the year 2021 produced an average root mean square error (RSME) value of 112.6 mm/month. Furthermore, the T-test analysis produced a 0.9 result. With air temperature, humidity, and pressure as predictors, the total monthly rainfall for 2021 was predicted with an average root mean square error (RMSE) value of 107.9 mm/month. A T-test was also performed, and the result was 0.4. The results of this study show that the monthly rainfall forecast model for the city of Pangkalpinang that includes factors related to temperature, humidity, and pressure produces better results than the model that only includes these variables. November and December are the months with the greatest variations.
A study on the quantitative recrystallization of cold deformed copper affected by tin-lead solder

It has been observed that the fractional recrystallization characteristics of commercially pure copper is affected by the presence of individual or both the constituent elements of the Sn-Pb solder alloy. In order to design the experiment, commercially pure Cu, binary copper alloys (Cu-Sn and Cu-Pb) and ternary copper alloy, Cu-Sn-Pb are investigated. Cast alloys are homogenized, solution treated, and then quenched to complete the thermal treatment. In order to recrystallize, alloys are cold rolled to a 75% thickness and then annealed at 700°K isothermally for varying durations, up to 3600 seconds. In this experiment, the fractional recrystallization of annealed samples is evaluated as the normalized difference in microhardness recorded at various time steps. Additionally, in an attempt to verify the experimental results, the well-known Johnson-Mehl-Avrami-Kolmogorov equation is also used to predict the associated recrystallization behavior. From the study, it can be inferred that the presence of Sn-Pb solder-alloy elements have a positive impact on the recrystallization behavior of pure copper due to the solid solution strengthening, in which the effect of tin is greater than that of lead. Quantitative analysis indicates that recrystallization of pure Cu, Cu-Sn, Cu-Pb, and Cu-Sn-Pb alloys attains 99.4%, 95.4%, 98.4%, and 89.5%, respectively. Sn forms intermetallic with Cu but Pb does not. Additionally, Sn forms different intermetallic with impurities and has a BCC crystal structure dissimilar to the FCC of Cu and Pb. As a result, the formation of GP zones and the intermetallic phases during annealing show greater differences in the recrystallization behavior between the two approaches. By combination, microstructural studies of the cold-rolled alloys reveal the elongated grains of the second phases, and the alloys almost completely re-crystallized after 1800 seconds of annealing at 700°K.

El presente artículo se deriva de una investigación teórica. En él se pretende describir el estatuto del deseo en la adicción a las drogas a través de las nociones de objeto, cuerpo y tiempo. Se toma distancia de la idea de la adicción como autoflagelo y se entiende mejor como una forma de resguardarse del dolor en un narcisismo absoluto, lo que se traduce en una desubjetivación por efecto de la “operación del phármakon”.
Dibujo político nepalí (1940-1970). Trazos de ironía contra el sistema Panchayat
Authors: De la Rubia Gómez-Moran Andrea
Published: July 2024

A través de la representación visual de los iconos nacionales de la montaña, el Rey y el Patrimonio Cultural de Katmandú, el arte contemporáneo nepalí se define como una herramienta que contribuye a romantizar la idea internacional del país como un mágico Shangri-La. Este artículo analiza la idea del dibujo contemporáneo a través del concepto de nepalidad como estrategia nacional promovida en los tiempos del régimen Panchayat (1962-1990). En un proceso que hibrida el realismo occidental con la cultura local, la intención del régimen era la de unificar su esencia multicultural de Nepal en torno a una sola cultura construida en torno al mismo. La Vanguardia nepalí utilizaba por tanto la nepalidad de forma casi forzada en sus obras, siendo la ironía el único medio a través del cual los artistas encontraban un resquicio para expresarse en contra de esta dictadura.

Published: July 2024

Umbilical cord blood has evolved from being considered a mere cellular/tissue waste product after childbirth to a valuable biological material with a wide regenerative potential. Today, hematopoietic cord blood stem cells are used in the same way as bone marrow and mobilised peripheral blood as part of the standard medical treatment for haemoblastoses and hereditary blood diseases. There is an increasing amount of experimental data showing possibility of umbilical cord blood cell fractions using for treatment of non-hematological diseases and, in particular, diseases of the central nervous system. One of the key challenges in cell therapy for central nervous system diseases is the choice of cellular material for neurotransplantation. This is particularly relevant for ischemic and traumatic injuries, as well as neurodegenerative diseases. Stem or mature somatic cells prepared for neurotransplantation should have predictable and reproducible characteristics thataccording therapeutic purposes, exactly: trophic and/or neuroprotective action to increase neurons viability in damaged area; axon growth stimulation and myelination; cell matrix restoration or predictable differentiation direction to replace amount of lost brain or spinal cord cells. The fact that umbilical cord blood contains not only hematopoietic, but also various non-hematopoietic stem cells with a wide regenerative potential has become the basis for active use of these cells for neurotransplantation. The proposed review provides historical information about umbilical cord blood introduction into practical medicine, its cellular composition and clinical applications of stem cells various types for children central nervous system diseases treatment, such as ischemic encephalopathy, stroke, cerebral hemorrhage, cerebral palsy, autism, and in adults — for stroke treatment, spinal cord injury and neurodegenerative diseases.
Psychology and psychopathology of overvalue hobby schoolshooing ideas. The case of Katerina and Yakov
Authors: Mendelevich Vladimir D. , Safina Roza S. , Koroleva Polina V. , Serebryakov Dmitriy F.
Published: July 2024

The article is devoted to the analysis of the phenomenon of extremely valuable passion for the ideas of school shooting (mass shootings in educational institutions). The case of 16-year-old Katerina and her 18-year-old friend Yakov, who were referred to psychiatrists after discovering preparations to commit a crime and activity in searching for information on the Internet about school shooting, is described. Since childhood, Katerina has been under the care of psychiatrists for mental, intellectual and speech development delays. She has been on disability since the age of 18 and has a history of playing games simulating murder and violence. The article examines the psychopathological and psychological factors that contributed to the formation of an extremely valuable passion for the ideas of school shooting among the surveyed. The article highlights the lack of seriousness and lack of concern displayed by Katerina and Yakov towards the issue of school shootings. Their tendency to joke about this topic and express sympathy for the perpetrators is also highlighted. The emphasis is placed on the careless, frivolous attitude of Katerina and Yakov to the problem of mass murders in schools, their tendency to joke about these topics and show sympathy for the killers. It is concluded that “understanding” the feelings of school shooters, the infantile desire to make something “cool” out of any life event, create a meme, laugh at something that is not customary to laugh at (“ethical inversion”) should be recognized as fertile ground for the formation extremely valuable passion for the ideas of school shooting, without the destruction of which it is impossible to cope with future tragedies in educational institutions.
Characteristics of depression treatment in men with testosterone deficiency
Authors: Osadshiy Yuriy Yu. , Soldatkina Svetlana V.
Published: July 2024

BACKGROUND: Treatment of depression in men with testosterone deficiency is particularly challenging because of the overlap between the symptoms of depression itself and those associated with testosterone deficiency, which requires the development of additional diagnostic and therapeutic approaches.
AIM: To enhance the effectiveness of comprehensive treatment of depression in men with testosterone deficiency.
MATERIALS AND METHODS: The study involved 140 male participants (aged 18–65 years) diagnosed with depressive episodes and recurrent depressive disorder according to the International Classification of Diseases, 10th revision. Patients were divided into the main group (testosterone levels below 12.1 nmol/l) and the control group (normal testosterone levels). The main group (n=90) was further divided into three therapeutic subgroups of 30 patients each: receiving sertraline monotherapy, testosterone monotherapy, and combined sertraline and testosterone treatment. The control group included men with depression and normal testosterone levels (n=50), who received sertraline only.
RESULTS: Depression in men in the context of testosterone deficiency has distinct clinical features, both phenomenologically and syndromally. The severity of the depressive syndrome in men with testosterone deficiency is lower (17.0 [16.0; 18.75] points on the HDRS scale) than in patients with normal testosterone levels (19.0 [18.0; 22.0] points on the HDRS scale), and the depressive episode tends to occur later in life (47.0 [42.0; 55.0] years) compared to those with normal levels of testosterone (29.5 [24.25; 40.0] years) and is less likely to be recurrent than in those with normal testosterone levels (29.5 [24.25; 40.0] years). The study of the efficacy and safety of depression therapy in the context of testosterone deficiency shows that a combined approach to the treatment of depression in men with testosterone deficiency has both advantages (considering the specifics of patients by normalizing testosterone levels and erectile function) and disadvantages (relatively higher risk of adverse events) compared to sertraline monotherapy.
CONCLUSION: The identified characteristics of the course and treatment of depression in the context of reduced testosterone levels allowed for the development of a more effective therapeutic and diagnostic algorithm.

BACKGROUND: Chronic pain syndrome is a highly prevalent condition that negatively affects the ability to work and quality of life, as well as worsening the prognosis of the disease and increasing the risk of early death. One of the most important scientific and practical medical tasks is the identification of risk factors for the transition of acute pain to chronic pain, which in the future will allow to develop mechanisms for preventing the development of chronic pain. It has been established that various psychological and psychopathological factors, in particular, personality traits and mental disorders, psychotraumatic events, make a significant contribution to the perpetuation of pain, but these data require clarification.
AIM: To determine the contribution of stressful events, personality profile and comorbid psychiatric disorders to the formation of chronic pain syndromes.
MATERIALS AND METHODS: The study included 105 patients aged 18 to 70 years with unexplained somatic or neurological pain syndrome that existed for more than 6 months and served as a reason for hospitalization. All patients underwent clinical-anamnestic and psychometric examination, statistical processing of the results was performed using SPSS Statistics v22.
RESULTS: In the course of the study, 4 groups of patients with psychiatric disorders comorbid with chronic pain were formed: 1 — chronic pain within the framework of prolonged reaction to stress\exhaustion disorder, 42 observations (12 men, 30 women); 2 — chronic pain within the framework of prolonged masked depressive episodes, 41 observations (6 men, 35 women); 3 — chronic pain as part of hypochondriacal spectrum disorders (limited hypochondria), 15 observations (8 men, 7 women); 4 — chronic pain as part of constitutional anomalies with a tendency to experience pain (pain prone personality), 7 observations (5 men, 2 women).
CONCLUSION: A significant association of chronic pain syndromes with stressful events has been established.
Rigidity of foot deformity in congenital clubfoot: foot stiffness index
Authors: Vlasov Maksim V.
Published: July 2024

BACKGROUND: A unified system for assessing the severity of congenital clubfoot in newborns and young children worldwide remains to be established. “Rigidity” of foot deformity refers to the degree of “resistance” of foot tissues during manual correction of elements of the deformity and is often used in subjective severity of foot deformity assessment. However, there is no objective quantitative assessment for the degree of foot rigidity.
AIM: The study aimed to introduce a novel clinical sign — ”rigidity of foot deformation”, which enables objective assessment of the severity of foot deformity in congenital clubfoot.
MATERIALS AND METHODS: Before applying the first plaster cast, a clinical dynamometric examination was performed on 350 feet of 229 children, followed by a mathematical calculation of the foot rigidity index. Statistical analysis was performed using the nonparametric Mann–Whitney U-test and Spearman’s rank correlation coefficient. Differences were considered significant at p 0.05.
RESULTS: Significant differences were found in all clinical and dynamometric parameters between congenital clubfoot of I–II, III, and IV degrees (p ≤ 0.05). Generally, the higher the degree of deformity, the more effort required to eliminate it, the smaller angle of simultaneous correction, and the higher index of foot rigidity. The results of Spearman’s correlation analysis of clinical dynamometric examination indicators in children with congenital clubfoot of I–II degree may indicate the mobile nature of the foot deformity; III degree, a rigid version of the deformity; and IV degree, an extremely rigid degree of deformity.
CONCLUSIONS: Rigidity of the foot deformity is a crucial clinical sign that characterizes the severity of the foot deformity, which has a quantitative characteristic — the rigidity index. Initial data on foot rigidity enables objective assessment of the severity of the deformity and selecting an individual approach to its elimination when applying staged plaster casts using the Ponseti method.

Published: July 2024

The development of instruments designed to assess student self-concept is crucial. This understanding of self-concept is based on the premise that it is a dynamic and ever-evolving construct. The concept of self-concept is initially conceived as a unidimensional structure but subsequently evolves into a multidimensional construct. The present study assesses the validity and reliability of the newly developed self-concept instrument. In Indonesia, there is a paucity of research that employs the Rasch Model to examine self-concept instruments, particularly in the context of the junior high school population. The objective of this study was to analyze the self-concept instrument using the Rasch Model with a sample of 113 students at the junior high school level. The research methodology employed is quantitative, with a cross-sectional design. The sampling technique employed was simple random sampling. The findings of the study indicate that the instrument effectively assesses the intended dimensions of self-concept. The reliability of the self-concept instrument is deemed to be of a high category, while the reliability of the self-concept item is considered to be of an excellent standard.
