Published: January 2025

Objective: to ascertain the prevalence and risk factors for bacterial translocation (BT) in brain-dead donors (BDDs) during organ and tissue retrieval in health care facilities.

Materials and methods. The study included 62 BDDs, featuring 44 males (71%) and 18 females (29%), aged 17 to 64 years. Organ was retrieved in healthcare institutions located in Gomel Oblast in 2019–2022. Bacteriological examination of biopsy material taken from different parts of the intestine, mesenteric lymph nodes (MLNs) and spleen was carried out. The presence of BT was validated when bacterial growth was obtained from homogenized MLNs and(or) spleen by isolating an identical strain from the intestinal lumen. The anthropometric characteristics of BDDs, hematologic, biochemical parameters, and the length of stay in the intensive care unit (ICU) were assessed.

Results. Evidence of bacterial translocation was detected in 22 BDDs (35.5%, 95% CI 24.7–48.0). Growth in MLNs and in spleen biopsies was noted in 21 (95.5%) and 7 (31.8%) patients, respectively. The BDDs were categorized into two groups depending on the presence of BT, and the main characteristics were compared. ROC analysis was used to determine the prognostic significance of the main parameters. Risk factors for BT were serum sodium level >144 mmol/L (AUC = 0.759) at the time of retrieval, weight >89 kg (AUC = 0.756), BMI >27.5 (AUC = 0.709), decreased hemoglobin <126 g/L (AUC = 0.665), and ICU stay >2 days (AUC = 0.656).

Conclusion. Bacterial translocation is found in 35.5% of BDD cases, and it is accompanied by penetration of bacteria and yeast-like fungi into the MLNs and spleen. Bacterial translocation is linked to excess body weight, hypernatremia, prolonged ICU stay, and decreased hemoglobin levels at the time of retrieval. These factors should be taken into account in the medical management of brain-dead donors (organ donor conditioning).

Background. Organ shortage remains an unsolved issue in the field of transplantology. It is particularly severe in such a progressive area as lung transplantation. The creation of extracorporeal systems for rehabilitation of donor organs has been made possible by perfusion techniques; however, the search for the best perfusion and preservation solutions remains important.

Objective: to evaluate the efficacy of the developed solution for preservation and normothermic ex vivo lung perfusion (EVLP), as well as to conduct a comparative analysis with the standard perfusion solution for EVLP.

Materials and methods. Experimental studies on small animal models were conducted. All animals were divided into 2 groups – control and experimental. The study stages consisted of: procurement of donor lungs, static cold storage, EVLP and orthotopic left lung transplantation. In the experimental group, the lungs were preserved using an experimental solution, while in the control group, they were preserved in PERFADEX® Plus (XVIVO, Sweden). Static cold storage lasted for 10 hours. Orthotopic left lung transplantation was performed after EVLP. The follow-up period was 2 hours, after which blood samples and sections of the transplanted lung were taken for morphological examination. Upon completion of the experiment, the animal was removed from the experiment by exsanguination.

Results. Respiratory index at the end of perfusion was statistically significantly higher in the experimental group (434 mmHg) than that of the control group (394 mmHg). Pulmonary vascular resistance (PVR) in both groups had a downward trend, which is a good prognostic sign of the efficacy of perfusion agents. PVR was lower in the experimental group compared to the control group – 36 versus 89 dynes/sec/cm–5.

Conclusion. The developed combined dextran-40-based solution showed its effectiveness as a preservation agent for static cold storage and as a perfusion solution for EVLP.

Published: January 2025

The desire of modern manufacturers to reduce the cost of producing goods leads to an increased search for ways to obtain the raw materials for future products more efficiently. One promising method for obtaining raw materials is electric arc surfacing (WAAM), which is discussed in this paper. The aim of the study was to investigate the effect of electric arc surfacing on the structure and fatigue strength of 30CrMnSi steel. To obtain the samples, two walls were surfaced according to the specified modes: I = 150 A, U = 25 V, Q = 600 J/mm (mode 1) and I = 110 А, U = 17 V, Q = 300 J/mm (mode 2). During the study of the walls microstructure after milling, it was found that when the metal is surfaced according to the mode 1, large accumulations of technological defects such as pores and bad welding form in the material. When the metal is treated according to the mode 2, these macroscopic defects are practically not detected. During optical emission analysis, it was observed that during the surfacing process, alloying elements are consumed and the carbon content decreases most actively. It should be noted that the burnout of elements occurs more actively when the metal is surfaced using the mode 1. This may be due to the higher energy input in this process. A predominant ferrite-sorbite structure was found in the metal surfaced using the mode 1. However, local ferritic colonies were revealed on the surface of the samples due to their height. The microstructure of the samples produced using the mode 2 is mainly composed of ferrite and pearlite. Ferrite is isolated as closed grids along the boun­daries of the austenitic grains, and traces of a Widmanstetten structure can also be seen. Perlite is present both as highly dispersed plates and partially spheroidized colonies. Despite the fact that the structure of the samples produced using the mode 1 is generally considered to be more favo­rable in terms of material properties, the fatigue strength of the samples produced according to the mode 2 exceeds that of the mode 1 by an average of 70 %. This may be due to the stronger influence of technological defects on the metal fatigue resistance than microstructural ones.

Published: January 2025

The authors investigated the microstructure and mechanical properties of wear-resistant coatings applied by the method of gas-thermal spraying with heating of the metal to a liquid state and its subsequent spraying with a gas jet. Nowadays, thermal spraying is increasingly an alternative to various methods of surfacing due to the high costs of consumables, the complexity of maintenance and safety during repairs. By this method, it is possible to reliably solve a variety of technological tasks, which include spraying of wear-resistant, antifriction and corrosion-resistant coatings; alitizing by spraying (increasing heat resistance); increasing the size of products; surfacing and soldering; elimination of casting defects; manufacture of molds, etc. The tribotechnical properties of the vibration damper rod of a railway carriage with reinforcing surface layers applied to the working surface by methods of gas-thermal spraying with 40Kh13 steel and galvanic chromium plating were investigated. Structure and thickness of the coatings, microhardness distribution in the coating-substrate zone, as well as the features of the coatings destruction under the same test conditions were studied. The criterion for comparing the coatings’ wear resistance was the operating time of the samples before the beginning of the coating destruction. Wear of the rollers was determined by the change in diameter, and wear of the pads – by the depth and width of the grooves formed on their surface during the experiment. The coating applied to the vibration damper rod by spraying 40Kh13 steel wire has high wear resistance in conditions of boundary friction with grease and can be an alternative to electroplated chrome coating. The high wear resistance of the coating makes it possible to recommend it for restoring the dimensions of worn parts and increasing the durability of new ones, as well as for replacing special anti-friction bearing alloys.

Published: January 2025

Novotroitsk Plant of Chromium Compounds (NPCC) specializes in the processing of chromite and dolomite ores. Operating experience showed that the loss of operability of the ball mill installed in this workshop leads to unplanned downtime due to the failure of drive elements, which account for 11.3 % of the rated operating time of the workshop. To improve the reliability of technological equipment, it was proposed to replace the existing electric drive with a modern geared motor, which transmits rotation to the mill drum through a gear coupling. As a result of the new drive engineering, it was possible to simplify its design and reduce the labor intensity of maintenance and repair. Additional capital expenditures do not exceed RUB 3.4 million and pay off in less than 3 months.

Authors:   Ufa State Petroleum Technological University, Yashin Anton N.
Published: January 2025

Relevance The well mechanized production is the most energy intensive of all technological oil production processes. This is because the number of wells is large, they are dispersed over long distances, many of them work in ineffective modes with significant unproductive losses. Electric drives of the rod of deep pumps work in underloaded mode with a cyclically changing load, which negatively affects both the electric network and the engine itself. To improve the energy characteristics of the electric drives of the sucker-rod pumping units must accurately balance the counterweights, as well as reduce the electrical power of the installed engines, which will increase the load coefficient. An urgent scientific task is to increase the efficiency of the installations of the rod deep pumps by balancing the counterweights-rocking machines, which in turn will reduce the electrical power of the installed engines, which will increase the load coefficient. Aim of research The main aim to investigate the relationship between the forces at the suspension point of the rods and the values of the active power consumed by the electric drive, taking into account the kinematic diagram of the pumping unit, the influence of inertial masses and the dependence of the rotation speed of the drive electric motor on the load. Research methods Theoretical and experimental research methods are used to achieve this goal. Theoretical research is based on theoretical mechanics and the theory of differential equations. The following software products were used in the research: MATLAB R2017b, MATHCAD. Results A model of the sucker-rod pump — rocking machine system has been developed with the possibility of taking into account the impact of changes in the parameters of a balancer balancing counter-load on the output parameters of the sucker-rod pumping units.

Mining-induced ground cracks in coal mining areas pose a significant threat to the ecological environment and the safety of individuals and property. To achieve sustainable development in mining environments and resource utilization, it is crucial to elucidate the formation mechanisms, types, development laws, research methods, and prevention strategies associated with ground cracks. In this paper, we classify mining-induced ground cracks based on various research purposes. Relevant research methods are summarized, and we systematically review the research progress on the development law of different mining-induced ground cracks. The unique development patterns of ground cracks in the Aeolian sand area of the western mining region in China are analyzed, highlighting a double cycle. Simultaneously, we explore prevention methods for mining-induced ground cracks. Results indicate that the evolution law and formation mechanism of mining-induced ground cracks are influenced by various geological and mining factors, showing complexity, diversity, and unity. However, research methods have their limitations. Building upon these findings, we propose a monitoring and analysis systems for mining-induced ground cracks to enhance real-time monitoring, data processing, and subsequent analysis. It is recommended to make further efforts in seven aspects. These endeavors aim to better comprehend the intricate behavior of ground cracks in coal mining areas, providing a theoretical reference for land ecological restoration.

В статье представлены результаты исследования, направленного на оценку вклада метакогнитивных навыков, сложившихся в учебной деятельности школьников, в регуляцию их онлайн-поисковой активности, осуществляемой в контексте образовательной деятельности. В исследовании приняли участие 158 обучающихся 10–11 классов общеобразовательных школ Санкт-Петербурга и Ленинградской области в возрасте 16,69±0,68 лет (84 девушки и 74 юноши). Сбор эмпирических данных осуществлялся с помощью опросника «Стратегии поиска информации в интернете» и анкеты самооценки метакогнитивного поведения «Метакогнитивные навыки в структуре учебно-профессиональной деятельности», модифицированных в соответствии с целью исследования. На основании полученных результатов сделан вывод о том, что метакогнитивные навыки связаны с оценкой различных компонентов онлайн-поиска тесными корреляционными взаимосвязями, которые носят преимущественно положительный характер, за исключением параметра «дезориентация», который связан с метакогнитивными навыками амбивалентно (положительно с «метакогнитивным контролем» и отрицательно с «процессуальными навыками» и «метапланированием»). Несмотря на это, значимым предиктором для всех компонентов онлайн-поиска оказалась только переменная «процессуальные навыки», продемонстрировавшая положительные регрессионные коэффициенты для зависимых переменных «оценка информации», «целеполагание», «пробы и ошибки», «выбор главных идей», «контроль» и «решение проблем», а также отрицательный коэффициент для «дезориентации». Помимо этого, значимым положительным предиктором «дезориентации» оказалась переменная «метакогнитивный контроль». Обсуждение результатов сфокусировано на направлениях психолого-педагогической работы по совершенствованию навыков информационного онлайн-поиска как элемента образовательной активности школьников.
Digital Skills’ Role in Intended and Unintended Exposure to Harmful Online Content Among European Adolescents
Authors: Tercova Natalie , Smahel David
Published: January 2025

Digital skills play a crucial role in shaping adolescents’ online experiences, serving both as a shield against harmful content and as a gateway to accessing it. Previous studies on online harmful content have predominantly focused on general exposure, overlooking the distinction between intended and unintended exposure (i.e., whether the adolescent deliberately sought out the content or was unexpectedly exposed to it). Moreover, existing studies did not consider the role of adolescents’ digital skills. This exploratory study aims to newly examine the role of the subtypes of digital skills in the intended and unintended exposure to harmful online content among adolescents from four European countries, as well as the influence of protective and risky factors according to the problem behavior theory. Using multinomial logistic regression, a sample of 3,934 adolescents aged 12 to 17 (M = 14.4, SD = 1.3; 51% boys) from Estonia, Finland, Italy, and Poland was examined. The results show different associations with respect to the type of exposure. For instance, knowledge skills and technical/operational skills were found to be associated with unintentional exposure to harmful online content, but not with intentional exposure. Similarly, the protective role of the family was suggested in intentional exposure but not in unintentional exposure. These findings underscore the importance of raising awareness among educators and parents regarding the dual nature of digital skills. Rather than solely emphasizing their protective potential, we shall acknowledge and address the potential risks associated with certain facets of digital proficiency.

Effectiveness of Peer Conflict Resolution Strategies in an Inclusive Preschool Unit – A Systematic Review
Authors: Zamkowska Anna , Majcher Daria
Published: January 2025

Introduction: The preschool stage is a time when children have many opportunities to develop their social skills and deeper comprehension thereof. The occurrence of peer conflicts is typical during this time, which, when properly resolved, can provide a developmental boost to children’s cognitive and social-emotional competencies. Intentional instruction by the teacher to support peer interactions increases children’s skills in this area. Children with disabilities who have lower social-emotional competencies, and, thus, perform less adeptly in conflict situations, may need special support. This is due to their difficulties in naming and understanding emotions, as well as reading the intentions of peers. The use of effective conflict resolution strategies by teachers can significantly affect the development of peer relationships and the process of integrating these children into the group.

Research Aim: The purpose of this article is to analyse the effectiveness of peer conflict resolution strategies in an inclusive preschool unit.

Research Method: A systematic review of scientific articles from Web of Science, Scopus, EBSCO, and Google Scholar for the years 2000–2024 was conducted using the PRISMA scheme. Nine full-text articles meeting all inclusion and exclusion criteria were analysed.

Results: The results indicate that the most effective programmes were those that developed the social skills of children with disabilities. Only two articles reported the effect size, in one study the effect was large while in the other, small, with the result being inconclusive.

Conclusions: The review indicates the need for further in-depth research, meeting high methodological standards, in this area, with a particular focus on the effectiveness of peer conflict resolution strategies implemented in preschool inclusion units.
Significance of thermoregulatory homeostasis in sustaining human physiological equilibrium
Authors: Dubey Shivam
Published: January 2025

Physiological control is based on homeostasis, which is the outcome of intricate interactions and competition between several negative and positive feedback systems. The dynamic process of thermoregulatory homeostasis may modify internal circumstances to withstand shocks from the outside world. Homeostatic management of the internal environment is responsible for the organism's health and vitality; knowledge of this idea is essential to a comprehension of normal physiology. In contrast, sickness is caused by disruption of homeostatic mechanisms, and effective therapy must try to re-establish these homeostatic conditions, working with rather than against nature.

The problems related to the treatment of surface runoff polluted by suspended solids are evaluated. The peculiarities of morphology and composition of suspended solids particles contained in surface runoff are considered. The design and the principle of operation of the developed experimental testing bench for tests to determine the efficiency of retention of solid particles by different filtering materials and life-size FOPS® filters are presented. It is shown that narrow particle size distribution fractions of natural zeolite can be used to evaluate both the retention of suspended solids by filter materials (or FOPS® filters) and the porous structure of fiber filter materials.

The soil-ecological condition of the sites after reclamation was analyzed and an attempt was made to demonstrate that it is possible to use NDVI vegetation index values as an additional tool for its assessment. It was found that in the areas where organ-accumulative embryozems dominate in the soil cover structure (more than 85 %) their soil-ecological condition is characterized as satisfactory (from 22 to 29 %). It was revealed that NDVI vegetation index for the reclamation sites (average value from three images for 2024) above 0.3 indicates the soil-ecological condition after reclamation of disturbed lands as satisfactory. It is concluded that the application of NDVI index as an indicator of soil-ecological condition of reclamation sites is possible, but for more accurate information it is necessary to create a database of long-term studies based on instrumental methods in the field.

Background: Delirium is a common challenge in pediatric open heart surgery intensive care units (OH-ICU). It is believed that emergence of delirium can lead to extended hospitalization periods. Therefore, we decided to investigate the association between delirium and its inciting factors in OH-ICU.
Methods: This was a cross-sectional study on 92 pediatric patients admitted to OH-ICU of “Children’s Medical Center” in Tehran, Iran, for more than 48 hours. To screen for delirium, the Cornell Assessment of Pediatric Delirium (CAPD ≥ 9) was utilized. Demographics, length of stay, development of complications, delirium, and factors associated with delirium were recorded.
Results: We observed 34 (37%) cases of delirium in patients in OH-ICU. We had 51% male patients and 49% female ones, with a median age of 8 (0.2-144) months.
11.5 hours (2-405) and they stayed in the hospital for a median of 4 days (2-31). The most common cardiac abnormality was ventricular septal defect (18%), associated with tetralogy of Fallot (TOF) (10%). Most of the patients (71%) experienced no adverse events during their stay; however, among those who did, vomiting and post-operation chorea were the most prevalent. Among the patients in our study, age [adjusted odds ratio (AOR) = 0.91], weight (AOR = 1.34), and sex (AOR = 0.31 for boys vs. girls) were significantly associated with delirium.
Conclusion: We observed delirium in 37% of the patients. Development of delirium in patients admitted to pediatric intensive care unit (PICU) was associated with younger age, female sex, and higher weight.

Published: January 2025

Background: Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune inflammatory disease predominantly affecting the central nervous system (CNS). Headaches, although common in patients with multiple sclerosis (MS), have been less studied in NMOSD. This study aimed to investigate the prevalence, characteristics, and associated symptoms of headaches in patients with NMOSD.
Methods: This cross-sectional study included 120 patients with NMOSD recruited from MS clinics in Isfahan City, Iran, between 2023 and 2024. Patients were assessed for headache prevalence and characteristics. An expert neurologist conducted examinations to exclude secondary causes of headaches and classified headache types according to the International Classification of Headache Disorders (ICHD-3).
Results: Eighteen patients (15%) reported headaches, all of whom were women. The average age of these patients was 41.27 ± 11.33 years, and the average onset age of NMOSD was 34.60 ± 12.12 years. Of the 18 patients, 14 were diagnosed with migraine and 4 with tension headaches. Patients with migraine reported more severe pain (severity score: 6.00 ± 1.42) than those with tension headaches (4.20 ± 1.35). Headache onset was equally likely to occur before or after an NMOSD diagnosis. photophobia, phonophobia, and nausea in patients with migraine, with a substantial impact on occupational disability reported by 57% of migraine sufferers and 50% of tension headache sufferers.
Conclusion: Headaches, particularly migraines, are prevalent in patients with NMOSD and significantly impact their quality of life (QOL) and occupational functioning. These findings emphasize the need for clinicians to recognize headache patterns in NMOSD for accurate diagnosis and effective management. Further longitudinal studies are warranted to explore causal mechanisms and develop targeted interventions.

Background: Multiple sclerosis (MS) is one of the most common progressive neurological disorders affecting young adults. This study aimed to perform a meta-analysis on the effect of interferon beta (IFN-β) on the quality of life (QOL) of patients with MS.
Methods: Using valid keywords and searching through databases like Medlib, ScienceDirect, PubMed, etc., 10 articles published between 1999 and 2020 were collected. The inclusion criteria were developed based on clinical guidelines, focusing on studies involving adults with MS treated with IFN-β, with outcomes measuring QOL. The exclusion criteria included studies not in English, those involving pediatric populations, or those lacking a control group. In the reviewed studies, 14 scales of QOL were measured at the beginning and the end of treatment with IFN-β. Stata software. Publication bias was not significant. Heterogeneity was evaluated using the Q test and the I2 index. In heterogeneous studies, subgroup analysis and meta-regression were used for meta-analysis. The random-effect model was used for analyses with I2 of more than 50%.
Results: A total number of 1320 people with an average age of 32.40 ± 8.77 years were included in this study. On average, there was a slight decline in energy and satisfaction with sexual function scales (SSF), while a slight improvement was seen in the other 12 scales, following the treatment with IFN-β. However, no significant changes were observed in any of the QOL scales following treatment, except for health distress (HD) (P < 0.001), role limitation due to physical problems (RLPP) (P < 0.001), and role limitation due to emotional problems (RLEP) (P = 0.037), all of which showed a slight but natable improvement. The physical and mental components, showed significant increases of 0.189 [95% Confidence interval (CI): 0.083, 0.295, I2 = 0%] and 0.221 (95% CI 0.119, 0.324, I2 = 0%) in the scores after using IFN-β, respectively.
Conclusion: This study's results showed that treatment with IFN-β does not negatively affect the QOL of patients with MS. Moreover, this treatment can slightly improve most QOL scales associated with the disability observed in MS.

Background: Early diagnosis of atherosclerosis, particularly in its subclinical phase, is crucial for reducing mortality and morbidity associated with cardiovascular diseases. This study aims to investigate the relationship between oxidative stress markers and coronary artery calcification (CAC), enhancing our understanding of the pathophysiology of CAC.
Methods: In October 2022, we conducted a systematic search of the Web of Science, Scopus, PubMed, and Embase databases without language or time restrictions, screening a total of 557 records. We excluded studies involving animals, in vitro experiments, reviews, case reports, clinical trials, editorials, and clinical guidelines. Eligible human observational studies (cohort and cross-sectional) that examined the link between CAC and oxidative stress markers were included. The Newcastle-Ottawa Scale was employed to assess the quality of the included studies.
Results: Our systematic review encompassed 40 studies, all of which included both male and female participants, predominantly using cross-sectional designs. Participants included individuals at low, intermediate, or high risk of coronary artery disease, patients with type 2 diabetes, those with existing cardiovascular disease, and asymptomatic individuals. The studies investigated various oxidative stress markers, including serum uric acid and 8-isoprostane, both of which showed strong correlations with CAC incidence and severity.
Conclusion: Oxidative stress markers may positively correlate with CAC scores, indicating a potential avenue for identifying individuals at heightened risk. This review underscores the need for further studies to facilitate early diagnosis of cardiovascular complications and the establishment of novel pharmacological targets.
