Published: September 2022

Cybersecurity is a vital part of a secure digital world. This paper is about quantitative analysis of the case study of the 8-week virtual internship program in Cyber Security recognized by AICTE and NASSCOM. The program's main objective was to train future professionals to possess good knowledge and skills in cyber security, specifically applying the skills to real-time scenarios. The internship constituted for Cisco Networking Academy institutions’ 2nd & 3rd year engineering students for the academic year 2020-21. Students completed the instructor-led, online self-paced courses: Introduction to Cyber Security (1.5 weeks), Introduction to Packet Tracer (1.5 weeks), and Cyber Security Essentials (2 weeks). Further, the students were invited to attend 5 sessions (1 week) conducted by industry experts to help students become career-ready and understand the career path in the cyber security industry. Furthermore, students worked on a project under the guidance of their instructor to design a secure network for their institution on the Packet Tracer simulation tool (2 weeks). On completion and submission of their project work, students completed the final quiz. Eligible 72 students who completed all the criteria received a virtual internship certificate from AICTE, NASSCOM, and Cisco. Students were evaluated before and after every step of the internship process. It was evident that there is a significantly positive effect of this internship on students’ skill acquisition (98.5%) and comprehension (92.2%) of network topology, (98.2%) of the students acquired a significant level of skills (software initiation skill - 98.7%; configuration skill - 92.3%; redirection skill - 93.1%; simulation skill - 98.7%; and connection skill 95.2- %) and students’ comprehension of network topology and cyber security concept was averagely high (98.8.5 %). The analysis concluded that the cyber security internship activity is a pertinent mechanism for stimulating students’ skills acquisition and comprehension of cyber security concepts, while also recommending that educators should use the Cisco packet tracer to allow students to gain practical and cognitive skills in the areas of computer networks and cyber security

Published: September 2022

It is important to introduce innovative teaching and learning methods to motivate students to develop thinking abilities and to motivate faculty to break monotonous lectures. There are multiple innovative teaching-learning methods, a few to name are crosswords puzzles, flipped classroom, mind map, Think share pair, one-minute paper, etc. This paper discusses the usage and impact of innovative teaching method, technical crossword puzzles. Simple puzzles on some specific topics are made using open source and trial softwares by giving the clues for the down and across. The crossword puzzle is given to a group of two students to solve within a time limit. Even though they need to focus and think a lot to solve a crossword, students also find it very interesting. They feel satisfied and accomplished if they can solve the whole puzzle correctly. From the faculty perspective designing a crossword by creating a set of questions with single-word answers that can be fitted into a crossword puzzle is a tedious task. Creating a puzzle by the faculty and solving the puzzle by a student is equally challenging and satisfying. Crosswords were created for multiple subjects like Systems Programming and OS, Artificial Intelligence, Computer Networking, etc. Feedback from the students is taken orally and in the written form which indicates that such innovative teaching-learning methods increase their focus, thinking ability, and interest in the subject and are fun. The feedback shows that 100% students enjoyed solving the puzzle. 92.7% students agreed that their thinking ability improved, 72.2% students say that they were able to recall the topics to solve the puzzle. 74.1% of students gave feedback that crossword puzzles can be a part of the evaluation system. 98.1% students also agreed that student interaction increased as they solved puzzles in a team.
Reshaping Learning and Teaching: Ensuring Equal Accessibility, Affordability and Multi-Disciplinary approach in Higher Education through Technology
Authors: Kanaiyalal Talsaniya Gauravkumar
Published: September 2022

The government of India crafted and then launched National Education Policy (NEP) on 29 July, 2020 to reform Indian education system that ensures equal access, affordability, quality, and accountability to each citizen. The policy targeted towards emerging demands and requirements for knowledge and skill to empower the citizen. It has many features including a new structure of 5+3+3+4 curricular that emphasises early childhood care, recognising a need for literacy and numeracy, introducing vocational education, technical education and internship in school from 6th grade, setting up a National Assessment centre called “PARAKH” to ensure learning and development, and ensuring education become more equitable and inclusive, especially to the socially and economically disadvantaged groups. There are some issues such as lack of modern infrastructure, low teacher ratio in schools, colleges and universities; fewer efforts to promote the English language from early education, and lack of resources to provide adequate skill and training to students that need to address for efficient implementation of new education policy. This paper attempts to address recent advancement in technology such as Artificial Intelligence (AI), Machine Learning (ML), and Internet of Things (IoT) plays a vital role to break such barriers and help the government at the initial stage to implement new education policy in an efficient and effective manner.

Authors: Sylvia Menezes Ida , Shwetha K. T.
Published: September 2022

Purpose: The purpose of this study was to develop a comprehensive tool to identify key components of leisure, thereby, examining the relationship between the prevalence of leisure (PLA) and psychological wellbeing (PWB); and its overall effect on the quality of life (QOL) of mothers of children with Autism-Spectrum-Disorder (ASD) with the demanding care of the child with autism.
Design/Methodology/Approach: A cross-sectional design with interpretivism and an inductive approach a sample of 140 mothers of children with ASD, in India was used to develop this instrument. Structural equation modeling (SEM), partial least squares structural equation modelling (PL-SEM), and chi-square were used to analyze the scale items. Research data was interpreted by exploratory factor analysis and Confirmative factor analysis. Reliability was explored through split-half and internal consistency estimation using Cronbach's alpha.
Finding/Result: The comprehensive outcome of quality of life (QOL) is measured as the result of engaging in the leisure of individual choice for self-replenishment, social connectedness, and happiness in life despite the demanding care of the child with autism. The overall unidimensional reliability with Cronbach’s alpha value of the scale is 0.656 having reasonably strong reliability. The construct-wise reliability demonstrated between 0.654 and 0.840 showing a high-reliability level. The validity of the instrument was established by face, content, construct, convergent, and discriminant validity tests. Most importantly the measurement model of the LsPQM-12 instrument has shown 0.935 CFI, 0.097 RMSEA, and 0.053 SRMR.
Originality/Value: Leisure-specific quality of life of mothers of children with ASD as an outcome of acknowledgment of prevalence of leisure as well as the absence of leisure made possible by the development of this instrument. Thereby integrating daily leisure of short duration despite the demanding care of the child, towards the psychological wellbeing of the mother was the sequel of this study. Appraisal of time of mother’s leisure schedules in parallel with the child’s therapeutic interventions to raise overall QOL is the objective of the study.

Anharmonic Properties of Oxides Having Face Centered Cubic Crystal Structure of Second Order
Authors: K. S. Kushwaha
Published: September 2022

A theory has been evolved for obtaining anharmonic properties of oxides having face centered cubic crystal symmetry using long-range Coulomb and short-range Born-Mayer potentials starting from the nearest-neighbour distance and hardness parameter. The second order elastic constants are obtained for oxides of Cd, Co, Fe, Nb, Ni, Te, Ti and Zr at elevated temperature. The room temperature data are utilized for obtaining the first order pressure derivatives of second order elastic constants, the second order pressure derivatives of second order elastic constants and partial contractions of these oxides. The results are presented and discussed.
(How) Visual properties affect the perception and description of transitive events
Authors: Schlenter Judith , Penke Martina
Published: September 2022

In a non-verbal aesthetic judgement task and a pre-registered production task, we tested how the orientation of the patient relative to the agent in a visual scene affects the perception and description of the depicted transitive event. Previous research has shown that a visual property like the position of the patient relative to the agent can affect speakers’ verbalization of events. Here, we investigated whether orientation constitutes another factor besides position that affects scene description. While speakers of German displayed an overall preference for scenes in which agent and patient faced each other, these scenes needed more time for sentence planning than the same scenes that showed the patient looking in the same direction and thus away from the agent. Moreover, we elicited more patient-initial sentences for face-to-face scenes than for same-direction scenes. The increase in patient-initial sentences was comparable to the increase in patient-initial sentences for scenes with left-positioned patients as compared to right-positioned patients. Based on our findings, we argue that manipulations of both position and orientation can change the prominence of the patient. The more prominent the patient (facing the agent, being placed to the left of the agent), the more likely speakers are to choose the patient as the sentence-initial subject. Hence, subtle changes of visual properties may affect not only how speakers perceive an event but also how they describe an event. Our findings are of relevance for a range of tasks that use visual materials.

Introduction

During the SARS-CoV-2 virus pandemic, immunosuppressive agents in treating chronic disease have become a concern, and rheumatic patients are not an exception. The controversies about the deteriorating effects of such medications led this study to evaluate the influence of biologic and conventional disease-modifying antirheumatic drugs (DMARDs) on the incidence of COVID-19 infection in rheumatic patients.

Material and methods

In the present cohort-analytical study, 512 patients with rheumatic diseases were enrolled during the COVID-19 pandemic (2020–2021). The incidence of COVID-19 infection was diagnosed according to the definition of the Iranian Ministry of Health. The frequency of COVID-19 infection in patients treated with biological and conventional DMARDs and glucocorticosteroids were compared.

Results

Among 512 rheumatic patients, 19.9% were definitely infected with COVID-19, and 23.3% of infected patients were hospitalized. Only one patient with vasculitis died during the two outbreaks. Our study showed that adding biologic DMARDs to conventional DMARDs did not increase the risk of COVID-19 infection. However, unlike biologic DMARDs, in conventional DMARDs, methotrexate increased, and hydroxychloroquine decreased COVID-19 infection. Regression analysis showed that prednisolone at a dosage higher than 10 mg/day increased the risk of COVID-19 infection 5-fold; hydroxychloroquine had a protective impact and reduced the risk of infection by 40%.

Conclusions

Biologic DMARDs and the type of selected rheumatic diseases in our study did not influence the susceptibility to COVID-19 infection. Prednisolone raised the coronavirus infection, and hydroxychloroquine played a protective role in the current study. Most of our patients showed good adherence to the health protocols. Further studies after worldwide vaccination are now required to reevaluate the influence of rheumatic diseases and DMARDs on COVID-19 infection.

No Estimation without Inference
Authors: Lohse Keith
Published: September 2022

The International Society of Physiotherapy Journal Editors (ISPJE) recently published an editorial warning that many of their journals would soon prohibit the use of null hypothesis tests and instead require authors to interpret 95% confidence intervals relative to clinically important values. Although I encourage the reporting of confidence intervals and the discussing of uncertainty in the context of a research question, the ISPJE’s proposed ban is illogical and there are several instances of flawed statistical reasoning in the editorial. In brief, the editorial: (1) fails to adequately grapple with the inherent connection between hypothesis testing and estimation, (2) presents several misleading arguments about the perceived flaws of hypothesis tests, and (3) presents an alternative to hypothesis testing that is, in itself, a form of hypothesis test – the minimal effects test – albeit done informally. If the editorials’ arguments are taken at face value, then that will lower the statistical literacy in our field and readers will have a flawed understanding of p-values. Further, if the editorials’ proposed ban is put into practice, I fear that could decrease the scientific integrity of our research as it removes quantitative benchmarks in favor of a more subjective interpretation of confidence intervals. Ultimately, I think that many of the ISPJE’s concerns that led to the editorial are valid, but I think those problems are the result of questionable research practices stemming from poor methodological training for authors, reviewers, and editors. These problems will only be fixed through better and continuing education, not the banning of statistically valid methods.

Science teaching without practical experiencescan make it difficult for students to understand the scientific phenomena studied. In this sense, the choice of didactic resources is animportant task in science education. The objective of this research was to analyze the use of didactic models in science classes in elementary school from the perspective of teachers. To this end, we chose to identify the students’ main difficulties,and the pedagogical practices most used to outline them, as well as to investigate the obstacles faced by teachers to develop and apply didactic models and, finally, evaluate their conceptions about the results achieved with these resources. The methodological approach of this research is quali-quantitative, with exploratory objectives,and its technical procedures characterize field research. The data were produced from the application of an online questionnaire answered by science teachers fromtheelementary school Carmelita Veras de Paulain the municipality of Barroquinha–CE. This research revealed important information about the applicationof didactic models and similar pedagogical practices in the participating school. The teachers pointed out that the diversity of pedagogical practices encourages participation and the search for knowledge, as well as, recognizedthat didactic models increase students’ attention and interest, promote participation,and facilitate understanding of the contents.

Published: September 2022

The Escola Família Agrícola Santa Ângela (EFASA) has a differentiable target audience, the student who lives in the countryside, and, because of this, it has a different perspective about the teaching form on curricular components of science to this public. Inthis context, the work aimed to describe the realization of the science fair at the EFASA school, to investigate the impact of the science fair, and its contributions to the teaching-learning process through the activities developed in this fair. The questionnaire online was applied through WhatsApp. After we elucidated and obtained the students' signatures in Informed Assent Termand Informed Consent Term only of their respective legal Guardians, students answered the questions. The data were arranged in graphs and tables. The students' responses were decisive for verifying that science fair can contribute positively to an experience of sciences acquiring knowledge, and it also was as a practical activity characterized. The results showed that the studentshave acted in a joined and organized way to pass on, produce and obtain knowledge during the science fair. Thus, the science fair could be a pedagogical strategy of teaching in science because it would provide practical, contextualized, and interdisciplinary learning among academic subjects of natural science, geography, and mathematics.

Authors: Sousa Sobrinho Aysllan
Published: September 2022

This work aimed to analyze the contextualization of physics teaching in high school based on theBNCC and point out suggestions for the application of the pedagogical assumptions set out in the document. For that, the bibliographical research on the BNCC is used as methodological aspects, defining as an action proposal a class on the physical properties of ceramic materials for high school students for the development of students regarding the document's guidelines. The results of the pedagogical action indicate that the contextualization of the contents gives meaning to the subjects studied, as students can perceive the relevance of applying knowledge to technological advancement, as they were able to assess the harms and benefits of the use of ceramic materials, through critical reflection on materials, as well as building the ability to argue and analyze proposals for intervention, considering ethical and environmental aspects historically linked to the scientific-technological development of materials, having as a point of interest the knowledge of physical properties. Thus, the approach suggested here didactically reflects the pedagogical assumptions of contextualization of teaching, according to the BNCC, for the development of essential skills and abilities for students.KEYWORDS: Ceramics.Physical properties.BNCC.Physics teaching.

An investigation into the criteria for project success within Transnet
Authors:   , Pillay Renee
Published: September 2022

Project Management is the wave of the future. This discipline and its evolution continues to be one of the principal means by which operational and strategic changes are managed in the enterprise. The importance of Project Management for organisational success will expand, rather than wane, in years to come. Projects, particularly large scale complex ones with multiple stakeholders, are failing at alarming rates despite a wide spectrum of efforts to solve the problem. The lack of meaningful results and outcomes is due, in part, to the fact that organizations tend to operate on a set of unproven assumptions concerning project objectives, business requirements, user expectations, motivations, agendas, schedules, costs and time frames. The management dilemma is that Transnet has committed R 65 billion to projects in the hope of developing its core businesses to that of world-class standards as a logistics service provider in South Africa. Transnet’s capital project division, Protekon, is responsible for managing the projects committed to this R 65bn capital expenditure. Transnet’s perception of Protekon’s failure to successfully deliver projects could result in appointments of external consultancies such as Hatch McDougal and Guba (HMG – an engineering consultant firm). Whereas, previously, Protekon was the monopoly service provider of engineering and project management skills within Transnet, Transnet’s sub-divisions appear to be utilizing outside consultancies more frequently. The reason for procuring engineering and consultancy services external to Transnet, among others, is the perception that Protekon is performing poorly in delivering successful projects. The outsourcing of work, fuelled by the negative perception of Protekon’s performance, directly impacts on the profitability of Protekon in the short to medium term. The objective of this dissertation was firstly to investigate the effect of Protekon’s involvement in Transnet’s project success; and secondly, to recommend strategies to improve the rate of project success, that could be applied within Transnet and Protekon.

Many people have used the term “charity shop” without having a clear understanding of it, even although there are numerous articles and a previous research survey about charity shops in the UK, Canada and Australia. It seems that no research has been done in South Africa on this particular topic. Also, the confusion that surrounds consumer perceptions of charity shops highlights the need for marketers to conduct more research on this particular area. The following study was conducted within the South African marketplace, specifically in four Durban areas, using quantitative research methods. The main objective of the research was to determine consumer perceptions of charity shops in the Durban area and the factors influencing these perceptions.

Introducción: Rhynchophorus palmarum L. es la plaga más devastadora en plantaciones de Cocos nucifera en México. Objetivo: Estimar el costo-beneficio de captura de R. palmarum mediante trampeo en dos genotipos de coco y determinar la correlación de captura con los factores ambientales. Materiales y métodos: Los insectos de R. palmarum se capturaron en los genotipos ‘Alto Pacífico ecotipo 2’ (AP) y ‘Enano-Verde de Brasil’ (EVB) durante un año. Se utilizaron cinco tipos de trampas (TC = tipo cubeta, TBB = tipo bote de basura, TG = tipo galón, CSAT = Colegio Superior de Agricultura Tropical, TB = tipo botella). La captura se contabilizó semanalmente y se determinó el costo-beneficio de trampeo. Las capturas se analizaron con distribución cuasi-Poisson, análisis de devianza y diferencia mínima significativa. La correlación de captura con las variables climáticas se determinó mediante coeficiente de Spearman.Resultados y discusión: En AP se capturaron 3414 insectos. La TBB y CSAT fueron las más efectivas (P < 0.014) con 40.3 % y 32.7 % del total de adultos, respectivamente; además tuvieron el mejor costo[1]beneficio, 4.3 MXN y 5.5 MXN por insecto respectivamente. En EVB se capturaron 3.56 veces más insectos (4799) que en AP con relación 29.6:6.4, utilizando TG. En ambas huertas, las correlaciones de las variables climáticas con la captura fueron débiles (menores de 50 %); la humedad relativa fue la de mayor correlación, pero negativa.Conclusiones: La efectividad de las trampas y su costo-beneficio permitirá a los productores determinar cuál trampa utilizar para el control mecánico y etológico (feromona de agregación) de R. palmarum

Artikkeli tarkastelee siirtolaistyövoiman sosiaalista tai yhteiskunnallista uusintamista jälkineuvostoliittolaisen poliittisen talouden kontekstissa. Venäjä on ollut vuosia yksi merkittävimmistä siirtolaisia vastaanottavista valtioista maailmassa. Keski-Aasian valtioiden taloudet ovat puolestaan huomattavan riippuvaisia Venäjällä työskentelevien siirtolaisten rahalähetyksistä. Ennen Venäjän hyökkäystä Ukrainaan helmikuussa 2022 Venäjän suurkaupunkien ja Keski-Aasian välillä kulki yksi maailman vilkkaimmista siirtolaisväylistä. Artikkeli tuo esiin, millaiset yhteiskunnallisen uusintamisen, huolenpidon ja hoivan käytännöt ovat pitäneet yllä tätä liikettä ja näin uusintaneet myös globaalisti ja alueellisesti eriytynyttä työvoimareserviä. Tutkimusaineisto koostuu Pietarissa ja Moskovassa työskentelevien keskiaasialaistaustaisten siirtotyöläisten päiväkirjamerkinnöistä. Analyysi osoittaa, kuinka vaurautta tuotetaan Venäjän suurkaupungeissa rodullistamalla, luokkaistamalla, sukupuolittamalla ja riistämällä siirtolaisten työtä. Samalla siirtolaisuuteen liitetty lupaus paremmasta elämästä muuttuu jälkineuvostoliittolaiseksi julmaksi optimismiksi.

O presente trabalho foi realizado com objectivo de estimar o vigor híbrido na população residente no município do Cazenga em indivíduos entre os dezoito e vinte e três anos re a escolha do local foi devido a uma observação directa da população existente naquela região, usamos especificamente a administração municipal como centro da recolha de dados, visto que por ela há grande frequência de indivíduos provenientes das diferentes regiões do município em questão. A recolha de dados efectuou-se utilizando as informações do bilhete de identidade de cada indivíduo e em muitos casos usamos uma fita métrica para a estimativa de estatura daqueles indivíduos que durante a recolha de dados não encontravam-se identificados. Notou-se maior dificuldade na recolha de dados dos progenitores juntamente com os respectivos descendentes e vice-versa, em muitas ocasiões tivemos que dirigir-nos a residência de ambos para a complementação dos dados. A amostra total foi de 696 indivíduos, destes 462 eram progenitores sendo 231 para o género feminino e o mesmo número para o género masculino, e os restantes 231eram híbridos. Usou-se parâmetros estatísticos para estimar o vigor híbrido como a média, variância, coeficiente de variação, desvio padrão, e a curva de distribuição normal. Utilizamos também testes genéticos como a diversidade genética de Nei, e o Teste de equilíbrio de Hardy e Weinberg e Herdabilidade. Verificou-se que do período de 1960 -2018 os homens no município do Cazenga cresceram em média 3,4 centímetros passando de 169, 5 centímetros para 172,8 centímetros, enquanto as mulheres cresceram em média 1,3 cm passando de 166 centímetros para 167,9 centímetros.

ANGINA PECTORIS WITHOUT OBSTRUCTIVE CORONARY LESION (PART 2). DIAGNOSIC METHODS IN CLINICAL PRACTICE
Authors:   Scientific and Practical Centre “Cardiology”, S. Solovey
Published: September 2022

Coronary vasomotor disorders are a common cause of angina pectoris without obstructive lesion of the coronary arteries (CA). Over the past decade, various non-invasive and invasive diagnostic methods have made it possible to comprehensively assess coronary vasomotor function and determine the endotypes of epicardial and microvascular dysfunction, which is important for stratification of cardiovascular risk and individualization of patient treatment. The basis for the diagnosis of the complex interaction of vasodilation and vasoconstriction of various parts of the coronary bed is a comprehensive intracoronary functional testing, which is recommended if the angina symptoms are persisting against the background of angiographically unchanged or moderately stenosed, blood flow non-limiting coronary arteries. The established parameters characterizing adequate vasodilation are coronary blood flow reserve and microvascular resistance. Increased vasoconstriction potential is diagnosed by intracoronary provocation test with acetylcholine, which allows verification of epicardial and/or microvascular vasospasm. The article discusses standardized criteria, non-invasive imaging methods and modern invasive examination algorithms used in the diagnosis of microvascular and vasospastic angina.

The study comprised 422 patients after aortic valve replacement with mechanical bicuspid valve prostheses of 19, 21, and 23 mm. The valves used were «Planiks-E», MedIng-2, Carbomedics, ATS Medtronic, St. Jude Medical. Hospital and long-term results are analyzed directly depending on the type-size of the AMHV used. There was a significant decrease in the peak and average transvalvular gradient on the all aortic valves (p < 0.0015), as well as an increase in the effective orifice area (EOA) of the aortic valve. EOA of the prosthesis “Planiks E” was not significantly different from that of its foreign equivalents. The EOA of St.Jude Medical prostheses was significantly larger compared to the Sorin Carbomedics prostheses (p > 0.005). The peak and mean gradients were different significantly (p = 0.007 and p < 0.05). The highest maximum systolic gradient was observed with Sorin Carbomedics prostheses. The phenomenon of prosthesis-patient mismatch of moderate degree in the early postoperative period was observed in 30.3% of patients, and in 4.1% it was severe. For “Planiks-E” prostheses, severe PPM was observed in 3.2% of patients. “Planiks-E” and ATS Medtronic prostheses were less common related to moderate PPM, in 27.80% and 28.60% correspondently. Overall hospital mortality was 3.4%. The risk of developing moderate PPN was 1.66 (95% CI 1.087 – 2.539, p = 0.19). The follow-up period mediana was 3.4 (2.12÷5.93) years. There were no significant differences in survival between patients without or with different PPM degrees (log-rank test, p = 0.539). Among “Planiks-E” the five-year survival rate was 87%.The PPN phenomenon did not significantly affect long-term survival. The heart valve prosthesis “Planiks-E” is comparable in its hemodynamic parameters to similar imported prostheses, the risk of moderate PPN being significantly lower.

Aim. To analyze long-term results of the use of minimally invasive epicardial video-assisted radiofrequency ablation (RFA) of the pulmonary veins (PV) in patients with various forms of isolated atrial fibrillation (AF). Materials and methods. Since February 2011 to December 2014, 22 patients (male/female – 21/1) with paroxysmal / persistent / long-standing persistent idiopathic form of AF were operated on the basis of the Republican Scientific and Practical Center “Cardiology”, 7 (31.8%) / 9 (41%) / 6 (27.2%) cases respectively. Mean age was 48.33 ± 9.37 (31–66) years old. The average duration of the history of AF before the operation was 58.6 ± 32.5 months. RFA was performed through a bilateral mini-thoracotomy approach using video endoscopy with the application of bipolar irrigated Gemini X ablative clamp electrodes. All patients underwent bilateral antral RFA isolation of the PVs. In 100% of patients it was possible to achieve a conduction block from the PV collectors. Results. During the hospital period, there were not no lethal cases, conversions to sternotomy, and neurological complications. The long-term period was studied in 100% of patients, the average follow-up period was 7.4+0.5 years. The final rhythm was assessed using Holter monitoring in 3, 6, and 12 months after surgery, then annually. In 6 (28%) cases in patients with initial non-paroxysmal AF, endocardial RFA of the isthmus of the right atrium or PV orifices was performed at different times after surgery due to the presence of atrial flutter (4/19%) or AF (2/9.5%). Implantation of the pacemaker was required in 2 cases (9.0%). The ef fectiveness of bipolar antral RFA isolation of the PV using the Gemini X device, depending on the initial form of AF in the long-term period: paroxysmal – 100%, persistent – 66.7%, long-term persistent – 33.3%. Conclusion. Epicardial minimally invasive bipolar antral PV isolation is a highly effective treatment for paroxysmal AF. In non-paroxysmal forms of AF, it is necessary to expand isolation of arrhythmogenic zones in the atria.

Background. Reperfusion injury occurs after revascularization of the coronary artery in patients with myocardial infarction (MI) significantly contributing to the development of chronic heart failure. This article describes the results of studying the effectiveness of one of the promising cardioprotection strategies aimed at limiting reperfusion injury. Materials and methods. Patients with acute anterior MI with ST elevation (STEMI) (n = 87) were included in an open-label prospective randomized controlled trial. Intervention group (IG) patients underwent primary percutaneous coronary intervention (PPCI) and remote ischemic preconditioning in combination with delayed postconditioning (RIPerPostC) (n = 43). Control group patients (CG) underwent only standard PPCI (n = 44). Event-free survival was estimated by Kaplan-Meier curves. Results. A comparative analysis of the frequency of the composite endpoint (re-hospitalizations for the underlying disease, repeated MI and death from cardiac causes) by the 36th month of follow-up had shown that the proportion of patients who reached the endpoint was significantly higher in the CG: 45.5% vs 20.9% in the IG (p = 0.015). According to the results of the log-rank test, there are statistically significant differences in the event-free survival of the analyzed groups (LR = 1.99, p = 0.047). The Kaplan-Meier curves of the CG and IG during the first 12 months after AMI did not differ visually in height and slope, which indicated the absence of intergroup differences in the cumulative functions of event-free survival during the indicated observation period. After 12 months, there was a discrepancy between the Kaplan-Meier curves due to the fact that the survival rate continued to decrease rapidly only in the CG. According to the survival function, in 25% of CG patients, adverse events occurred within the first 13 months after AMI. Taking into account censored observations, the cumulative proportion of patients without major clinical events 36 months after AMI in the IG was 74% versus 38% in the CG. Conclusion. In patients with STEMI the DIPerPostC method in combination with PPCI has a positive effect on patient survival over 36 months in comparison with isolated PPCI. The highest number of adverse events occurred during the period from 12 to 36 months of observation in the CG.

Aim. To study early and long-term clinical outcomes in patients with unstable angina (UA) and coronary artery stenting based on the results of a seven-year follow-up. Materials and Methods. The study included 165 patients with UA and coronary artery stenting. The average age of patients was 59.04±10.34 years; the number of male patients was 129 (78.2%). The risk by the GRACE scale was 96.9±17.46 points. The average number of affected coronary arteries was 2.23±1.07 per person, the average number of implanted stents was 2.10±1.45 per person, the average length of the stented area was 43.12±25.6 mm. Everolimus- or sirolimus-eluting stents were used. All patients were assessed for troponin I, myeloperoxidase, and C-reactive protein; platelet, plasma, and vascular hemostasis were evaluated. The patients underwent echocardiography, coronary angiography. The follow-up period was 7±1.6 years. Results. During a 7-year follow-up period, with endovascular treatment strategy and double antithrombotic therapy with clopidogrel 75 mg and acetylsalicylic acid 75 mg repeated UA developed in 91 (55.2%) pts and myocardial infarction was registered in 21 (12.7%) pts. Cardiovascular mortality was 7.3%. Independent stent thrombosis risk predictors included AUC ADR test ≥ 77.5 U, troponin I ≥ 0.90 ng/ml, total length of the stented area ≥ 60 mm. Independent predictors of the development of restenosis/neoatherosclerosis included: more than 4 implanted stents per patient (RR 1.440; 95% CI 1.233-1.681), the total length of the stented area ≥ 60 mm (RR 1.532; 95% CI 1.245-1.884), homocysteine ≥ 14 µmol/l (RR 1.479; 95% CI 1.168-1.876), myeloperoxidase ≥ 300 pmol/l (RR 1.351; 95% CI 1.102-1.656), with risk factors including a history of coronary heart disease for more than 5 years (RR 13.011; 95% CI 4.226-40.050), diabetes mellitus (RR 1.367; 95% CI 1.136-1.647). Conclusion. The number of early and long-term coronary events in patients with unstable angina and coronary artery stenting was estimated. Predictors of stent thrombosis, restenosis and the formation of new atherosclerotic plaques outside the stenting zone were identified.

The aim of the study was to assess the cardiovascular status of large-forgestational-age (LGA) and small-for-gestational-age (SGA) full-term newborns. A survey of 192 newborns was carried out on the basis of the Republican Scientific and Practical Center “Mother and Child”. Group 1 (Gr1) consisted of 54 large-for-gestational-age newborns, group 2 (Gr2) – 43 small-for-gestational-age newborns, group 3 (Gr3) – 95 newborns with physical development corresponding to gestational age (appropriate for gestational age). Echocardiographic parameters were compared between study groups, as corrected to body surface area. Morphometric assessment of heart structures in the course of Echo-CG in Gr1 patients showed a statistically significant thickening of the heart walls with predominant localization in the posterior wall of the left ventricle (LV) and interventricular septum (IVS). Significant differences were found in all derivatives of echocardiographic indicators in the examined groups of newborns. In Gr2, signs of diastolic myocardial dysfunction were revealed reflecting an impairment of the age-related evolution of myocardial relaxation processes. The intragroup analyses of LGA and SGA neonates (subgrouped according to the birth weight percentile) revealed no statistically significant differences in the direct and derived echocardiographic parameters analyzed. The frequency of detection of open foramen ovale (PFO), IVS thickness of 5.0 mm and more in LGA newborns had greater as compared with the group of conditionally healthy infants (р = 0.038, р = 0.001). Fetal communications in SGA newborns occurred significantly more often (PFO – р = 0.031, patent ductus arteriosus – р = 0.026) than in newborns with normal weight. LGA and SGA newborns are characterized by the specific cardiovascular status. The revealed changes make it possible to assign infants with large and small birth weight to the risk group for the development of cardiovascular pathology, which requires dynamic observation as well as therapeutic and prophylactic measures.
