Authors:   Department of Educational and Scientific and Technical Activities of the Ministry of Emergency Situations of Russia, Bondar A.I.
Published: June 2022

Based on the need to improve the quality of tasks assigned to scientific and educational institutions of the Ministry of Emergency Situations of Russia, proposals have been developed for their integration into a model of a corporate university. The problems of the current educational model of personnel training in educational institutions of the Ministry of Emergency Situations of Russia, as well as the importance of innovative approaches in the scientific activities of specialists of the Ministry of Emergency Situations are outlined. On the basis of mathematical modeling, proposals were made to introduce a system of independent awarding of academic degrees, rationalize scientific activities taking into account current global trends, increase sources of funding for scientific institutions of the EMERCOM of Russia through the provision of scientific and technical services on a reimbursable basis. In general, the introduction of these proposals into the system of scientific and educational institutions of the EMERCOM of Russia should improve the quality of training of highly qualified personnel, published scientific publications and works for the competition of academic degrees, and this, in turn, will allow the institutions of the EMERCOM of Russia to fulfill their tasks at higher level.
WEEDINESS AND YIELD OF SUGAR BEET UNDER DIFFERENT METHODS OF CROP CARE
Authors:   Penza State Agrarian University, Zheryakov E.V.
Published: June 2022

In field experiments carried out in the conditions of the forest-steppe of the Middle Volga region, the influence of various methods of caring for crops on the productivity of sugar beet was studied. For the period from 1998 to 2018.weed infestation of sugar beet crops increased from 52.5% to 55.3%, while the number of all root weeds increased from 1.1 to 6.1 pcs/m2, and sow thistles and plume thistles - from 3.20 to 7.05 pcs/m2. It was noted that at the beginning of the growing season, the number of weeds increased sharply (by 2.8 times) from the phase of mass shoots of the crop to the beginning of the closing of leaves in the inter-row spaces, then the rate of emergence of new weeds decreased, and starting from the phase of opening the rows of sugar beet it increased again (by 1, 3 times).Сounting the number of weeds made it possible to establish that the implementation of three chemical treatments leads to an increase in the number of weeds by the time sugar beets are harvested. If in the initial period of sugar beet growth the number of weeds in the variant with three inter-row treatments was more than 90 pcs/m2, in the case of chemical treatments it was more than 60 pcs/m2, then the opposite was observed during the harvesting period. As a result of the research, it was found that the highest yield of root crops was obtained during three herbicidal treatments.
Mitigation as a way of resolving or preventing conflicts in diplomatic speech
Authors:   Russian-­Armenian (Slavonic) university, Tunyan S.
Published: June 2022

During the implementation of communicative attitudes in various types of both personal and institutional discourse, particularly in diplomatic discourse, the most frequent category is mitigation – the category of communicative relaxation, for the implementation of which in every language there are certain means, as it allows you to correctly place accents, to direct the illocutionary force of the statement in the right direction. The article presents the essence and history of this term, its pragmatic component in the diplomatic discourse.
DIALOGUE ABOUT THE SOUL AND THE SPIRITUAL: N.V. GOGOL AND ST. IGNATIUS (BRYANCHANINOV)
Authors:   Lomonosov Moscow state University, Voropaev V. A.
Published: June 2022

The article examines the review of St. Ignatius (Bryanchaninov) about N. V. Gogol’s book «Selected Places from Correspondence with Friends» in the light of the categories of the soul and the spiritual. According to Gogol, literature should perform the same task as the works of spiritual writers – to enlighten the soul, to lead it to perfection. This is, to his mind, the only justification for art; its purpose is to serve as an invisible step to Christianity. In the Christian trichotomy «body – soul – spirit», culture and literature belong to the sphere of the soul. A peculiar result of the correspondence dialogue between two outstanding representatives of Russian culture, classics of Russian literature, can be the words of the New Martyr Archpriest John Rapture that such creators as Gogol, in their meaning in the history of the word, are similar to the holy fathers in Orthodoxy.
The specificity of the psycholinguistic parameters “representability” and “the similarity of the image with the picture” of tuvan words in the linguistic consciousness of tuvan-­russian bilinguals
Authors:   Tuvan State University, Natpit A. A. ,   Siberian Federal University
Published: June 2022

The nature and structure of the mental lexicon, as well as the process of speech reproduction, are hot topics in cognitive linguistics and other related disciplines. The results of research by scientists in this field have a significant contribution to the fight against aphasia. In this publication, we will consider the results of an experiment with 58 bilinguals to measure two psycholinguistic parameters of Tuvan words: representability and similarity of an image with a picture. Word representability determines how easily and quickly the respondent can imagine the stimulus word. In case of a speech disorder, the higher the value of this parameter for a word, the higher the probability of its preservation or restoration in the patient’s mental lexicon. The parameter “similarity of the image with the picture” reflects how the picture is equivalent to what the informant imagines when he reads the word. This parameter is important in the selection of stimulus material for speech therapy.
ON THE TRAGIC BEWILDERMENT IN THE WRITINGS OF PUSHKIN AND GOGOL
Authors:   Saint Petersburg State University, Filonov E. A.
Published: June 2022

The article attempts to apply the concept of “tragic bewilderment”, which relates back to the Nevel philosophical school (in particular, to the works of Matvei Kagan), to interpret the patterns of the creative evolution of Alexander Pushkin and Nikolai Gogol. Overcoming tragic bewilderment, Pushkin and Gogol rethink the nature of the relationship between literature and extra-­literary reality: they move away from the idea of the aesthetic autonomy of art and open up new possibilities for literature, associated with its dialogic appeal to the world of the reader.
«Slanderers of Russia» in Pushkin’s and Gogol’s contexts
Authors:   The Herzen State Pedagogical University of Russia, Annenkova E. I.
Published: June 2022

The article examines the poems of Alexander Pushkin, which were a response to the Polish uprising of 1830–1831, as well as to the reception of this historical collision in Western society and journalism. For the first time, Pushkin’s reflections on the relations between Russia and the West are analyzed in comparison with the position of N. V. Gogol, which found expression in his book «Selected Passages from Correspondence with Friends» (1847); some semantic overlaps are found between the works created by writers at the final stage of creativity. For both, the question of the nature of the word and the possible forms of its use by a poet, journalist, and politician is important. It is established that Pushkin perceived the problem «Russia – the West» not only in the historical, but also in the ontological aspect; the vocabulary of the poems «To the Slanderers of Russia» and «Borodino Anniversary» reflected Pushkin’s understanding of the Christian worldview and the poet’s conviction that the West did not understand the peculiarities of the Russian world. An analysis of such chapters of Gogol’s books as «On what a word is», «Fears and horrors of Russia» allows us to talk about the author’s actualization of the Christian context and about the possibility and the possibility of further comparing Gogol’s and Pushkin’s texts in a new way.

“Ordinary” as a set of extraordinary in the artistic sociology of F. M. Dostoevsky
Authors:   Voronezh State Pedagogical University, Savinkov S. V. ,   Voronezh State University
Published: June 2022

The article presents a detailed commentary on the place of the novel “Idiot”, in which the typological characteristics of the community of ordinary people are presented. The impossibility of change and development turns out to be the defining feature of this category, but it is no longer due to the table of ranks. An ordinary person, being a representative of the multitude, dreams not of reaching the cherished step in the official hierarchy, but of knowing by everyone what he initially does not have – originality. Belonging to a multitude of ordinary people, an ordinary person opposes himself to him, thereby declaring his inequality with him and at the same time equality with those geniuses of humanity with whom he cannot have equality by definition.
The Use of Logging Machinery Sets in the Republic of Bashkortostan

Published: June 2022

The disintegration of the integrated logging enterprises, as well as of the forestry enterprises and the reduced attention of the authorities to the production of specialized machinery and equipment, the logging production process, have led to a decline in the equipment of the logging enterprises with specialized machinery and the effective organization of their operation. Small, privately owned, poorly equipped with machinery logging companies have emerged. Practically we reverted to the technology of the 1960s. Foreign chainsaws are used for felling, delimbing and crosscutting. The skidding operation practically uses general-purpose tractors of МТЗ-80(82) type with the simplest technological equipment – a set of chokers. Some of the larger companies use foreign harvesters and forwarders. According to our research, forestry farms of the Republic of Bashkortostan are in a similar position. In order to increase the level of equipment and improve the organization of its work at the enterprises of the Republic of Bashkortostan we have considered and proposed for use a number of machinery sets. However, practice shows that it is not enough to acquire and equip the production with modern machinery and equipment. A production process must be set up to ensure the effective operation of these machines. Logging as a complex, multi-operated, discrete process can be carried out using a variety of technologies. The most common technology nowadays is the logging and hauling of assortments, for which various harvesting machines and equipment can be used. For the effective operation, harvesting machines performing individual operations are combined into machinery sets. However, current practice shows that it is not possible to match machines and equipment with the same or slightly different capacities. Therefore, the output of such sets is usually equal to, or even lower than, the output of the operation with the lowest capacity. In order to increase the output of the machinery set to the output of the leading machine (the machine with the highest capacity), it is necessary to calculate the modes of operation of machines for specific operating conditions. There are five sets of logging machines offered. The costs that the use of each of them will require are calculated. On the basis of the obtained data it is concluded that in the conditions of the Republic of Bashkortostan it is most economically feasible to use the following set: chainsaw for felling, choker tractor for skidding, two chainsaws for delimbing and crosscutting, lumber carrier for hauling.
Powdered Paper-Resin Films as Reactive Fillers for Urea-Formaldehyde Resins

Powdered paper-resin films (PRF) composed of melamine-urea-formaldehyde resin and bleached pulp seem to be promising fillers for plywood glues as they increase the viscosity of the glue composition and interact chemically with the components of ureaformaldehyde resins. It is generally accepted that when 4–6 % PRF is mixed with ureaformaldehyde resin, the viscosity of the glue increases by 80–110 %, however the increase in viscosity is followed by an increase in the gelatinization time of the glue by 25–35 %. The reactivity of the films defined by the polycondensation rate of urea- and melamine-ureaformaldehyde oligomers was studied by determining the residual hydroxymethyl groups in the cured adhesive compositions. Our results show that when we add PRF into the resin, the content of unreacted hydroxymethyl groups increases from 1.0 % of a composition without any fillers to 2.5 % of a composition with 10 % of films in it. We found that the content of unreacted hydroxymethyl groups in the cured glue depends on the gelatinization time of the glue composition by 90 %. To speed up the glue curing, we replaced the ammonium chloride with a more effective curing agent МО-4СБ (Russian abbreviation), which helps to reduce the time of gelatinization time by 15 % for a mass fraction of 4–5 %. The content of hydroxymethyl groups in the cured glue with 4 % of PRF and 4–5 % of МО-4СБ was 0.6–0.7 %, which is 30–40 % less than in the resin without fillers. Samples of 3-layer plywood that contain 4 % of filler and 4 % of modifier-curing agent МО-4СБ had a glued seam that was 5 % stronger that of a control plywood sample which consisted of 8 % of kaolin and 1% of ammonium chloride. The increase in strength has reduced the rate of glue consumption by 15 % while meeting the requirements of the State Standard GOST 3916.1–2018 for the physical and mechanical parameters. As a result, using 4 % PRF as a filler for glue made from urea-formaldehyde resin helps to increase the viscosity of the glue on par with other mineral fillers. In addition, it increases the strength and the water resistance of the cured polymer. The growth of the physical and mechanical parameters occurs due to the polycondensation of urea- and melamine-urea-formaldehyde oligomers. However, an acceptable reaction rate requires the use of more effective curing agents than ammonium chloride.

Preservation of wooden architecture monuments requires special attention since during their operation for 100 years and more wooden structures are exposed to environmental influences resulting in weakening their bearing capacity. The use of external reinforcement systems for buildings of historical value leads to a loss of architectural look. The proposed method of restoring the bearing capacity of the destructed wooden beams in the support zones is based on modification with a polymer composition. We have considered 3 types of pine beams: destructed, modified in the support zones; wooden, weakened by destruction; “healthy”. Numerical calculation of beams with a length of 6 m and a cross-section of 100×200 mm is performed in the Lira software package. The calculation model of the beams considered was created by adapting the initial data for the working environment of the software package used. The computational model is set as a three-dimensional body obtained by triangulation and “extrusion” of beam projection section. Shear stresses in the supporting zone, as well as vertical movements of the beams have been determined according to the developed method of calculation of wooden beams. The parameters of the modified beam and the reference “healthy” structure were compared. Shear stresses in the strengthened beam are 15–17 % higher than in the “healthy” beam. It was found that the strength of the destructed beam modified on supports increased by 16–18 % compared to the destructed beam. The boundary conditions for the modification of destructed wooden beams in the support zones to restore their bearing capacity have been determined on the basis of the obtained results. If the loss of bearing capacity is more than 35 %, then this method is not recommended due to the expediency of replacing such structures.
Modeling the Forest Stand Growth Dynamics Based on the Thermodynamic Approach

Published: June 2022

The forest ecosystem is a common example of the functioning of open thermodynamic systems. The work analyzes the change in the entropy of an open thermodynamic system where the following processes can be realized: absorption of short-wave solar radiation – differentiation process; total biomass growth process associated with the consumption of resources for respiration and competition. As a result of these processes, the negative entropy flow enters the system, and the positive entropy is produced in the system. As the stand grows, its biomass reaches a maximum, which corresponds to the steady state in the ecosystem. It is shown that, in accordance with the Prigogine’s theorem, the specific entropy production in an open system takes on a minimum positive value. With a further increase in the age of the stand, the steady state of the open thermodynamic system evolves to an equilibrium state, at which a decrease in the plant biomass is observed, and the entropy tends to a maximum value in accordance with the 2nd law of thermodynamics (ecosystem decay). The analysis of the behavior of an open thermodynamic system forms the basis of a new ecological and physiological model of the stand growth dynamics. The model proposed uses the following parameters: the biomass of an individual tree and the number of trees per hectare. In order to model the biomass growth dynamics of an individual tree, the von Bertalanffy equation is used. It contains a dynamic equation describing growth of an individual due to resource uptake and limitation of growth due to resource consumption. The equation that characterizes the dynamics of stand size derives from the condition of reaching the maximum biomass of the stand during the stand’s growth. In general, the stand’s dynamics model has only three independent parameters. They are the onset time of the steady state, the resource consumption rate and the factor linking the area and biomass of the organism. The model verification is presented by calculating the biomass dynamics for full (normal) pine plantations of the first five quality classes (Ib, Ia, I, II, III). The model’s quality is assessed by the dimensionless Nash-Sutcliffe model efficiency coefficient, the value of which is usually greater than 0.95. This corresponds to a description of the data that is close to ideal.

State forest shelterbelts are not only one of the components of the ecological framework of sparsely forested steppe territories, but also represent a unique object of steppe afforestation. Age-related changes and a long-term absence of forestry impact negatively affected the sanitary condition of plantations of the state forest shelterbelts. The research is aimed at assessing the current state of the plantations that form the shelterbelts in different soil and climatic conditions in the steppe zone of the European part of Russia. The plantations of the coastal state forest shelterbelts “Voronezh – Rostov-on-Don”, “Belgorod – Don River” and watershed “Volgograd – Elista – Cherkessk” were the research object. The expediency of using the method of remote sensing of the Earth is due to the significant extent and differences in the state of the research object in different soil and climatic conditions. An analysis of the natural conditions of the research region made it possible to determine the boundaries of 5 forestry regions on the main subtypes of zonal soils: ordinary chernozems, southern chernozems and dark chestnut soils; chestnut soils; light chestnut soils with the presence of solonetz and sometimes solonchak soils; and also on azonal sandy soils. Based on the data of our own field surveys of artificial plantations, the interpretation of space images of state forest shelterbelts was carried out using the learning algorithm and spectral indices in the ENVI 5.2 software package. As a result of interpretation, it was found that the safety of state forest shelterbelts decreases as forest conditions become more severe from ordinary chernozems to light chestnut soils from 92.3 to 36.5 %. Oak forests, ash forests, and elm forests predominate in the species composition on zonal soils, and pine forests predominate on azonal soils. With the deterioration of forest site conditions, the share of oak in plantations decreases, it is replaced by elm, the density of plantations decreases. Forest strips on chernozems, dark chestnut and sandy soils are also the most prosperous in sanitary terms. Plantations growing on chestnut and light chestnut soils are characterized by digression increasing with age or complete decay of the forest environment. The conducted research allows to identify the location of plantations in the stage of degression or decay within the state forest shelterbelts, and to recommend for them the nature and volume of forestry impact for the conservation and restoration of the forest.
Pre-service Teachers’ Perceptions of Teaching English
Authors:   Aoyama Gakuin University, Takagi Akiko
Published: June 2022

The purpose of this study was to examine pre-service teachers’ perceptions of teaching English and the reasons behind these perceptions, based on positive and negative learning experiences prior to starting their pre-service teacher education program. The participants were 200 Japanese pre-service teachers in an English teaching methodology course from five cohorts at a private university between 2015 and 2019. These individuals recorded their reflections on their prior learning experiences in the personal statement section of the JACET SIG on English Language Education’s (2014) reflection tool, The Japanese Portfolio for Student Teachers of Languages. The results of a thematic analysis revealed seven categories of learning experience. Moreover, the reasons participants cited for evaluating their experiences as being either positive or negative involved affective, cognitive, and linguistic factors. Teacher educators working in teacher preparation programs would benefit from taking into account the nature of student teachers’ preconceptions about teaching before encouraging reflection on and development of their didactic knowledge. 本研究の目的は、英語科教員養成課程を履修する前の肯定的及び否定的な経験に基づき、教員養成課程の学生の英語教育に対する認識とその背後にある理由について調査することであった。参加者は、2015年から2019年に、私立大学で英語科教育法特論の授業を受講した5グループ200名の学生であった。彼らは、『成長のための省察ツール：言語教師のポートフォリオ』（JACET教育問題研究会,2014）の「自分自身について」のセクションにおいて、学習経験を振り返り記述した。テーマ分析の結果、学習経験について7種類のカテゴリーが明らかになった。また、参加者が経験を肯定的または否定的と評価する理由として，感情的、認知的、言語的要因が挙げられた。教員養成課程に携わる教師教育者が、履修生の教育に対する先入観を考慮した上で、教授法の知識についての省察と向上を促すことは意味があるであろう。
Training modulates memory-driven capture
Authors: Sasin Edyta , Sense Florian , Nieuwenstein Mark , Fougnie Daryl
Published: June 2022

Attention is captured by information matching the contents of working memory. Though many factors modulate the amount of capture, there is surprising resistance to cognitive control. Capture occurs even when participants are instructed either that an item would never be a target or to drop that item from memory. Does the persistence of capture under these conditions reflect a rigidity in capture, or can properly motivated participants learn to completely suppress distractors and/or completely drop items from memory? Surprisingly, no studies have looked at the influence of extensive training of involuntary capture from working memory items. Here, we addressed whether training leads to a reduction or even elimination of memory-driven capture. After memorizing a single object, participants were cued to remember or to forget this object. Subsequently, they were asked to execute a search task. To measure capture, we compared search performances in displays that did and did not contain a distractor matching the earlier memorized object. Participants completed multiple experimental sessions over four days. The results showed that attentional capture by to-be-remembered distractors was reduced, but not eliminated in subsequent sessions compared with the first session. Training did not impact capture by to-be-forgotten objects. The results suggest observable, but limited, cognitive control over memory-driven capture.

Published: June 2022

Background: Bone mineral density (BMD) testing is indicated for women aged 65 years, but screening strategies for osteoporosis are controversial. Currently, there is no study focusing on the BMD testing interval in Asian populations. The current study aimed to evaluate the estimated time interval for screening osteoporosis.Methods: We conducted a study of 6,385 subjects aged 50 years and older who underwent dual-energy X-ray absorptiometry screening more than twice at Samsung Medical Center as participants in a routine health checkup. Subjects were divided based on baseline T-score into mild osteopenia (T-score, <–1.0 to >–1.5), moderate osteopenia (T-score, ≤–1.5 to >–2.0), and severe osteopenia (T-score, ≤–2.0 to >–2.5). Information about personal medical and social history was collected by a structured questionnaire.Results: The adjusted estimated BMD testing interval for 10% of the subjects to develop osteoporosis was 13.2 years in mild osteopenia, 5.0 years in moderate osteopenia, and 1.5 years in severe osteopenia.Conclusion: Our study provides extended information about BMD screening intervals in Asian female population. Baseline T-score was important for predicting BMD screening interval, and repeat BMD testing within 5 years might not be necessary in mild osteopenia subjects.

Methods: Cross-sectional study design was employed, there were 228 children with disabilities aged 1 to 15 years old in Quang Xuong district, Thanh Hoa province. Regarding types of disability: Children with mobility difficulties made up the highest percentage (50.0%), followed by children with learning difficulties (17.1%) and difficulties in listening and speaking (14.0%). The levels of disability were mild (6.6%), severe (73.2%), and especially severe (20.2%). The most common cause of disability was congenital (91.2%). The percentage of children with a disability for 5 years was 71.0%. Among children with disabilities, 50% fall within the category of mobility difficulties. Most children had severe or especially severe disabilities. Most of these disabilities were congenital. It is crucial to develop programs for early detection and early treatment of children with disabilities in the community as well as to promote rehabilitation programs at home. It is essential to provide education for mothers about health during pregnancy in order to ensure adequate nutrition for mothers and children, periodical antenatal check-ups, and the prevention of infection and injury which will all help reduce congenital disabilities.

ESTIMATING THE REAL SHOCK TO THE ECONOMY FROM COVID-19: THE EXAMPLE OF ELECTRICITY USE IN CHINA
Authors: Liu Lu , Huang Junbing , Li Hong
Published: June 2022

Quantifying the shock to the economy from the COVID-19 pandemic is difficult. Although this shock is easily linked to financial markets as a sort of monetary shock, few studies have been done on its effect on the real economy. This study takes a particular economic perspective, focusing on electricity uses in various sectors of the economy. We propose a novel method for comparing electricity use in 2019Q1 and 2020Q1, based on which we derive the degree of the real shock to some important economic sectors from COVID-19. In our theoretical framework, demand for energy and its influencing factors are related to the total scale of the economy, i.e., the gross domestic product. Using suitable empirical methods, we obtain certain marginal effects and then calculate the corresponding ratio as the real shock from COVID-19. The ratio between these marginal effects reveals the need for a balance between stocks and the corresponding differences in the economy. In our cases, the electricity use in various economic sectors plays a role in both stocks and the differences. We find that, although manufacturing and consumption are affected, the services are more vulnerable to the shock from the COVID-19 pandemic. Our findings offer implications for policymakers.

Objective: In the process of PET/CT scanning, patients go through a general evaluation while their medical history is being taken, but it is often overlooked that these patients should be evaluated not only biologically but also bio psychosocially. Psychiatric symptom profiles and help-seeking behaviours of cancer patients were examined in this study.
Methods: Cancer patients presented to nuclear medicine clinic filled out sociodemographic data form, psychiatric admission evaluation form, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Symptom Checklist-90 (SCL-90) form for psychiatric symptom screening.
Results: In this study 27.8% of the patients had a Beck Depression score ≥18 and were in the risk group for depression, 31.7% of the patients experienced moderate or severe anxiety symptoms. Beck Depression Total and Beck Anxiety Total values were found significantly higher in women than in men. Only 10,2% of the cancer patients reported that they sought psychiatric help in the last 6 months. Among the patients who were risky for depression according to BDI only 25%  had been receiving psychiatric help and in among the patients who were risky for anxiety according to BAI only %26.9 had been receiving psychiatric help
Conclusion: Nuclear Medicine physicians' interest in psychiatric symptoms and help-seeking behaviors of cancer patients referred to Nuclear Medicine Clinics is very important in terms of psycho-oncology.

Published: June 2022

BACKGROUND: Antimicrobial resistance is one of the world’s problems. It occurs due to misuse of antimicrobials in dealing with infectious diseases, making antimicrobial drugs less effective in treating infectious diseases. Antimicrobial sensitivity pattern is useful for directing clinicians in empirical therapy and preventing antimicrobial abuse so that resistance to antimicrobial drugs does not occur.

AIM: This research is conducted to identify the microorganism spectrum and its sensitivity pattern at the intensive care unit (ICU) of a secondary care teaching hospital in Tangerang, Indonesia.

METHODS: This study is a cross-sectional observational retrospective study done in the ICU of secondary care teaching hospital in Tangerang, Indonesia from January 2019to June 2020. This study used 1,341 isolated extracted from the ICU of a secondary care teaching hospital in the Tangerang database. All the samples would be analyzed using Microsoft Excel 2013 and Statistical Package for the Social Science 25 (SPSS 25) using ANOVA analysis.

RESULTS: From 1,341 isolates, the most common microorganism found was Klebsiella pneumoniae 221(16%) and the most common specimen is sputum 905 (67,48%). Gram-negative bacteria had the highest sensitivity to amikacin 62% and imipenem 59%. Gram-positive bacteria had the highest sensitivity to tigecycline 98% and doxycycline 95%. While Candida spp. had the highest sensitivity to micafungin (96%) and voriconazole (97%).

CONCLUSIONS: This study showed that the sensitivity of antimicrobials was no longer effective in treating infection. Therefore, the government and doctors must play an important role in socializing the correct way of using antimicrobial.

Authors: Abdel-Salam Lubna O. , El Hanbuli Hala , Abdelhafez Dalia Nabil
Published: June 2022

Background: Pancreatic ductal adenocarcinoma (PDAC) is world-widely considered as one of the most malignant tumors. Programmed cell death protein 1 (PD-1), via its ligands PDL1 and PDL2 plays a critical role in cancer immunoediting. The ligands are expressed in many solid tumors and there is an emerging hope of using anti-PDL in cancer immunotherapy.
 
Material and methods:
This study included 40 patients with PDAC who underwent pancreaticoduodenectomy. PDL1 and PDL2 pancreatic expression were evaluated in these patients using immunohistochemical staining and correlated their expression levels with each patient’s reported clinicopathological features.
 
Results:
There were significant relations between high tumoral PDL1 expression and the PDAC tumor histologic grade (p= 0.021) and the tumor status (T) (p= 0.022), while the stromal expression of PDL1 showed non-significant relation with any of the studied features. There were significant relations between high tumoral PDL2 expression and tumor stage (p=0.012), while the stromal expression of PDL2 showed significant relation with tumor status, lymph node status, tumor stage and the presence lympho-vascular invasion with P value equal 0.001, 0.009, 0.009, 0.045 respectively.
Conclusion:
This study showed that in PDAC patients high tumoral PDL1 and PDL2 expression was associated with some important prognostic factors, while only stromal PDL2 expression was significantly associated with most of the studied prognostic features emphasizing a role of both markers in the prognosis of this neoplasm.
Angiotensin-converting Enzyme Insertion/Deletion Polymorphism (rs4646994) and Susceptibility to Acute Lymphoblastic Leukemia: A Case–control Study
Authors: Abdulaziz Al Romisa Ahmed , Ali Elshazali Widaa
Published: June 2022

BACKGROUND: Angiotensin-converting enzyme (ACE) stimulates the proliferation of bone marrow hematopoietic progenitors and thought to be involved in pathological neoplastic hematopoiesis and leukemogenesis.

AIM: This study aimed to investigate the association between ACE gene I/D polymorphism and the risk of acute lymphoblastic leukemia (ALL).

MATERIALS AND METHODS: A total of 96 subjects were recruited for the study, 48 patients with ALL, and 48 apparently healthy volunteers as a control group. Genomic DNA was extracted from peripheral leukocytes and ACE I/D polymorphism was analysed using allele-specific polymerase chain reaction.

RESULTS: In both study groups, the ACE D/D polymorphic genotype was the most frequent (52.1% and 54.2%, respectively), followed by the ID genotype (47.9% and 45.8% respectively), while the II genotype was completely absent in both study groups. The distribution of the polymorphic genotypes among the study groups was not significantly different (p = 0. 0.398). The frequency of the D allele was 0.76 in the patients and 0.77 in the control group, while the frequency of I allele was 0.24 in the patients and 0.23 in the control group. No deviation from Hardy–Weinberg equilibrium was observed (χ2 = 4.24, df = 1, p = 0.12).

CONCLUSION: ACE I/D polymorphism is not associated with susceptibility to ALL among the Sudanese population.

Published: June 2022

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) spectrum ranges from simple hepatic steatosis to non-alcoholic steatohepatitis. Considering the restrictions of liver biopsy, various serological biomarkers have recently emerged for non-invasive diagnosis of NAFLD.

AIM: This study aimed to evaluate the association between serum neuregulin 4 (Nrg4) and NAFLD and the use of serum Nrg4 as a noninvasive marker for diagnosis of NAFLD.

METHODS: Sixty-three Egyptian NAFLD patients and 63 controls were enrolled and subjected to detailed history taking, thorough clinical examination including anthropometric measures (body mass index [BMI] and waist circumference). Laboratory investigations included complete blood count, lipid profile (total cholesterol, low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein-cholesterol [HDL-C], triglycerides), serum albumin, transaminases, bilirubin levels, hepatitis markers (anti-HCV antibodies and hepatitis B surface antigen), anti-nuclear antibodies and anti-smooth muscle antibody. Measurement of serum Nrg4 by ELISA and non-invasive NAFLD scores such as NAFLD fibrosis score and FIB4 score were applied to all patients.

RESULTS: There was a statistically significant difference between cases and controls regarding the BMI, waist circumference, hemoglobin level, total leukocytic count, total cholesterol, LDL-C, HDL-C, and serum triglycerides levels. Nrg4 was significantly decreased in NAFLD patients as compared to controls. Moreover, Nrg4, total cholesterol, and LDL-C levels were statistically significant independent predictors of NAFLD. No significant differences were observed between Nrg4 level and the variable stages of hepatic fibrosis by NAFLD fibrosis score.

CONCLUSION: Decreased serum Nrg4 level is frequent in NAFLD patients and is an independent predictor of NAFLD, suggesting that Nrg4 might have a potential role in prevention and treatment of NAFLD.

Published: June 2022

BACKGROUND: Acute heart failure is a life-threatening medical condition. Thus, effective therapy is very important for this case. Utilization of standard therapy and adjunctive isosorbide dinitrate (ISDN) pump play an important role in reducing mortality, length of hospitalization, and national early warning score – NEWS 2. However, the research on the utilization of the ISDN pump as adjunctive therapy is still limited.
AIM: This study aimed to analyze the association between utilization of standard therapy and adjunctive ISDN pump with clinical outcomes (mortality, length of hospitalization, and NEWS 2) in patients with acute heart failure.
METHODS: This was a cohort retrospective observational study. The purposive sampling technique was utilized to select the acute heart failure patients in UNS Sukoharjo Hospital. All the data were obtained from medical records. Logistic regression was used to analyze the data.
RESULTS: A total of 94 patients were included as the samples. There was a significant association between the utilization of standard therapy (OR=7.9; CI 95%= 3.1–20.4; p < 0.001) or ISDN pump (OR=0.3; CI 95%= 0.1–0.7; p < 0.001) with the length of hospitalization. However, there was no significant association between the utilization of standard therapy (OR=1.1; CI 95%= 0.2–6.6; p = 0.9) and ISDN pump (OR=0.2; CI 95%= 0.02–1.6; p = 0.1) with NEWS 2 on patients with acute heart failure.
CONCLUSION: There was a significant association between the utilization of standard therapy and ISDN pump with the length of hospitalization.
