Authors: Yılmaz Başer Hülya , Akgümüş Alkame , Balun Ahmet
Published: May 2024

Purpose: The aim of this study is to assess the detectability of coronary artery stenosis in patients evaluated for acute myocardial infarction (AMI) in the emergency department and undergoing coronary angiography, based on blood parameters examined in the emergency setting.
Materials and Methods: In our single-center prospective observational study, patients diagnosed with AMI in the Emergency Department between September 1 and October 31, 2023, and those who underwent coronary angiography by a single cardiologist were included. The blood parameters applied during routine assessment in the Emergency Department were recorded, and parameters with predictive effects based on the percentages of vessel stenosis after angiography were evaluated.
Results: A total of 64 patients (44 males and 20 females) who met the study criteria were included in our research. Following the evaluation based on the highest percentage of stenosis in any coronary artery after coronary angiography, patients were divided into two groups. Group 1 consisted of 15 patients with mild stenosis (stenosis
Optimizing the functional state of the cardiorespiratory system of female students aged 17-19 with the help of a modified program of distance classes in physical education
Authors: Pavelko O.M.
Published: May 2024

The article deals with the peculiarities of the impact of a modified program of distance training on physical education on the functional state of circulatory systems and external breathing of students of 17-19 years of higher education. The relevance and practical importance of this study is due to the complex modern conditions of life of our country, the inability to conduct full -fledged classes among student youth and the need to maintain the optimal level of physical and functional state of student youth.
The use among female students of the experimental group of the program of remote classes proposed by us contributed to significantly higher rates of improvement in heart rate, all types of blood pressure, Robinson's index, total peripheral resistance of blood vessels, coefficient of efficiency of blood circulation, vital capacity of the lungs (in 2-3 times), breath retention time on inhalation and exhalation (3 and 5 times, respectively), Skibinsky index 5 times, hypoxia index (20 times) and almost 5 times the levels of the functional state of the cardiovascular system and the external system breath. The results of changes in their intragroup distribution by the levels of levels of functional state of circulatory and external respiration, which were reflected in the increase of their representation in functional classes high and above average, were significantly more optimal in the experimental group. Similar changes in the girls of the control group were insignificant. The results testified to the high efficiency of the proposed program of distance classes with the use of fitness and the possibility of its practical use among students of higher education.
Modern material and technical support of the educational and training process in rowing at the stage of basic training
Authors: Redkva Yrii
Published: May 2024

The article examines modern views on the training of rowing athletes, as well as the importance of using modern technical means in the training process. As a result of the literature analysis, it was found that when working with rowers at the stage of basic training, insufficient attention is paid to the operational analysis of information obtained during the training process. The relevance of this study is also due to the fact that the issue of the possibility of using modern technical means and portable devices by rowing athletes has not been covered in the scientific literature.
The purpose of the work was to determine which technical means are used by rowers in the training process and to determine their priority in the opinion of the athletes themselves.
The article describes the results of a questionnaire about the use of material and technical means and equipment in the training process of rowers aged 14-16 at the stage of basic training.
It was found that the priority element of the training process according to the rowers is the material and technical base, namely: a gym, a modern paddle and special sports clothes. At the same time, the vast majority of respondents said they would like to be able to train with modern technical equipment such as wearables and GPS.
Information from portable devices makes it possible to analyze the capabilities and physiological characteristics of athletes. This helps the athlete and coach to receive automatic feedback on how to improve personal results and prevent injuries.
The use of portable devices in combination with modern inventory requires further research. In the future, we plan to develop a training program for rowers 14-16 y.o. with the use of portable devices in the training process.
A Literature Discourse on the Development of Islamisation of Knowledge Models: Strategising New Project Based Implementation Approach to Benefit Human Sciences
Authors: Hossain Dewan Mahboob
Published: May 2024

The movement of Islamisation of Human Knowledge is no more a new issue among the Muslims. This intellectual movement involves a desecularisation of knowledge in order to show the Muslim Ummah the true path of leading life. A major objective of this article is to identify the problems and prospects in the implementation of Islamisation of Knowledge on human sciences. This article first highlights the proposed methodologies of Islamisation of Knowledge suggested by different prominent Muslim scholars. Then a critical evaluation of all these models is presented. The study concludes that though many scholars suggested many models of Islamisation of Knowledge, implementation of these models is still passing through an early stage with some irregularities to consolidate between Islamic component and human sciences. The article proposes a time bound project based approach for the implementation of Islamisation of Knowledge at educational institutions.

Authors: Ibrahim Mohsin. , Habeeb Ahmed. M.
Published: May 2024

Appropriate revascularization decision and proper conduit selection are the most important factors to maintain adequate coronary flow and the function of the coronary bypass grafts after coronary artery bypass graft (CABG) surgery. Left internal mammary artery (LIMA) is considered to be the gold standard choice graft for bypass surgery, as its patency rates are around 90-95%, ten to fifteen years after CABG. Here, we report a case of a 58-year-old man who underwent CABG six months ago and presented for evaluation and management of worsening angina. Cardiac catheterization revealed total occlusion LIMA and severe stenosis of saphenous vein graft (SVG) in the presence of patent right internal mammary artery (RIMA).

Published: May 2024

Extra-pulmonary manifestations of severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] infection such as cardiovascular complications have been reported and previous case reports have documented evidence of myocardial damage. Currently, very few case reports of the arrhythmias associated with Coronavirus Disease 2019 [COVID-19] exist. In this case series, we demonstrate two cases of critically ill COVID-19 patients with cardiac rhythm abnormalities that might be a direct or indirect consequence of this infection. Each of the patients experienced a variety of cardiac rhythm abnormalities. None of the patients had any record of cardiac rhythm abnormalities prior to admission. The unique point of these cases is the multiple dysrhythmias in the same patients that have not been reported previously. We demonstrated that critically ill COVID-19 patients develop different arrhythmias ranging from sinus tachycardia, bradycardia, atrial fibrillation, supraventricular tachycardia, and non-sustained ventricular tachycardia. Non-sustained monomorphic ventricular tachycardia was the most common arrhythmia in the two cases despite normalization of electrolyte imbalances and avoidance of QTc prolonging agents.

Authors: Mardani Mojdeh , Salahuddin Muhammad , Stupnisky Robert H.
Published: May 2024

Underrepresented minority (URM) university faculty can be identified as those whose representation based on gender, race, and/or ethnicity in particular fields, such as Science, Technology, Engineering, and Math (STEM), are smaller than in the US population. Studies on URM faculty have found discrimination and affiliated stress impact faculty in many aspects of their work, such as performance in research. In the current study, we examined STEM faculty who self-identify as URM, their experiences of workplace discrimination, and how these encounters affect their self-determined motivation to conduct research. Six-hundred and fifty-one faculty from 10 US institutions completed an online survey. Of the participants, 37.5% self-identified as URM, of which 81% were women, 20% non-white, and 6% Hispanic/Latinx ethnicity; notably, the data shows that 24% of women and 56% of non-white faculty did not self-identify as URM. More than 87% of URM reported workplace bias, which correlated with significantly lower autonomy and relatedness with coworkers. URM women reported gender discrimination at work was common and upsetting, which related to greater amotivation. Non-white and Hispanic/Latinx/Spanish URM who reported high success in research also cited more discrimination. URM faculty motivation was fostered by autonomy and competence, and much more by relatedness compared to non-URM faculty. For non-URM, autonomous motivation (enjoyment, value) positively related to research success, whereas for URM faculty a lack of introjected motivation (guilt) was the strongest predictor. Discussion focuses on implications for future studies of faculty motivation and strategies to promote URM faculty research productivity.

Objective: This study was aimed to evaluate intensity of infestation and annual distribution of termite community in palm orchards in southern governorates of Iraq (Basra and Maysan) to develop appropriate integrated management programs to control termite (Microcerotermis diversus Selvestry) in palm groves. Methods: A field survey was conducted for a whole year(October 2022- September 2023) to evaluate termite community, also relationship between intensity of termite infestation with some palm varieties was studied, and a correlation was made with some important contents for termite vitality in tissues of the frond bases such as Proteins, carbohydrates, phenols, and lignin were estimated to determine which varieties are more tolerant to termite infestation and the most sensitive. Results: Survey showed that palm varieties Khadrawi and Shakkar most susceptible to invasion, with rates of 52.19 and 48.4 termites/frond base, respectively. As for the Barhi and Al-Maktoum cultivars, they had lowest percentage of termite infestation, with 0 and 10.0 termites/frond base, respectively. Conclusions: Termite (Microcerotermis diversus Selvestry) prefers to invade some palm varieties that have a suitable content of carbohydrates and proteins (Khadrawi and Shakkar), especially in the moderate and cold months of the year. Termite community decrease in hot months of the year; therefore we recommend carrying out integrated termite management operations at the beginning of October and November in palm groves in arid and semi-arid areas similar to the areas of southern Iraq.

Published: May 2024

Study Design: Feasibility study.Purpose: A phantom model was used to evaluate the accuracy of a novel augmented reality (AR) system for cervical screw placement.Overview of Literature: The use of navigation systems is becoming increasingly common in spine procedures. However, numerous factors limit the feasibility of regular and widespread use of navigation tools during spine surgery. AR is a new technology that has already demonstrated utility as a navigation tool during spine surgery. However, advancements in AR technology are needed to increase its adoption by the medical community.Methods: AR technology that uses a fiducial-less registration system was tested in a preclinical cervical spine phantom model study for accuracy during spinal screw placement. A three-dimensional reconstruction of the spine along with trajectory lines was superimposed onto the phantom model using an AR headset. Participants used the AR system to guide screw placement, and post-instrumentation scans were compared for accuracy assessment.Results: Twelve cervical screws were placed under AR guidance. All screws were placed in an acceptable anatomic position. The average distance error for the insertion point was 2.73±0.55 mm, whereas that for the endpoint was 2.71±0.69 mm. The average trajectory angle error for all insertions was 2.69°±0.59°.Conclusions: This feasibility study describes a novel registration approach that superimposes spinal anatomy and trajectories onto the surgeon’s real-world view of the spine. These results demonstrate reasonable accuracy in the preclinical model. The results of this study demonstrate that this technology can assist with accurate screw placement. Further investigation using cadaveric and clinical models is warranted.

Вітаміни мають вирішальне фізіологічне значення в підтримці функціонального стану нервової системи. Ця важливість вітамінів обумовлена їх функціональними значеннями для організму, адже в забезпеченні життєдіяльності організму приймає участь біля 30 вітамінів та вітаміноподібних речовин. У той же час неналежне їх споживання може стати причиною різних побічних реакцій, які особливо можуть виникати при прийомі високих доз деяких вітамінів.

Israel on the Cusp
Authors: Lustick Ian S.
Published: May 2024

Political scientists distinguish between governments and regimes. A government is comprised of incumbents holding positions of authority specified within an institutionalized “regime,” that is, a legal order. Within a well-institutionalized regime, politics consists of legal struggles over what governments and government officials do. But when the issues in contention pertain to what governments are authorized to do, and not about what they should do, competitors may no longer feel bound to follow the rules. Such struggles can threaten the integrity of the regime. This article suggests that the prolonged, if temporarily sidelined, crisis over the overhaul of the Israeli judiciary should be understood less as a threat to democracy than as both a challenge to the Israeli regime's remaining liberal features and as an early skirmish in what will be a long political war over whether and how to emancipate millions of non-citizen Palestinian Arabs living in effectively annexed territories.
“COGNITIVE FRAGMENTATION” AS A CONSEQUENCE OF CLIP THINKING AND ITS IMPACT ON MODERN SOCIETY EVOLUTION
Authors: Mohylnyk A. , Vishnikina L. , Tarasenko K. , Suprunenko S. , Davydenko A.
Published: May 2024

In today’s information-saturated world, individuals are inundated with verbal and visual messages, leading to the development of what is termed “clip thinking” as an adaptive response. This phenomenon, characterized by constant interaction with superficial and nonsensical texts, alongside continuous internet browsing, has profound implications beyond mere cognition.
Clip thinking, a systemic issue, extends its influence beyond cognitive processes. Its roots lie in the transmission of information through modern gadgets, the ubiquity of the internet, and the prevalence of clip culture. Modern youth, constrained by the small screens of digital devices and the constant scrolling of text, are increasingly averse to engaging with complex material, resulting in decreased information retention and comprehension.
This shift in information consumption habits has concerning implications for higher education. Many students rely heavily on electronic aids, neglecting memorization and overlooking the importance of understanding complex texts. Consequently, the prevalence of fragmented thinking among students leads to deficiencies in conceptual and critical thinking skills. Instead of engaging deeply with subject matter, students often resort to generalized concepts, overlooking causal connections.
Carriers of clip thinking become vulnerable to any manipulations by the mass media, as the mosaic nature of their consciousness is capable perceive only what is happening right now and information provided through information and telecommunication gadgets without subjecting it to critical analysis. Hence, university lecturers face significant challenges as they endeavor to navigate the need for innovative teaching methodologies in light of the fragmented thinking prevalent among modern students.
The searching for innovative teaching technologies should not solely aim at altering the thinking patterns of students with clip-like cognitive tendencies. Rather, the primary objective of modern educational technologies should be to foster the mental skills necessary for information analysis and synthesis, as well as the identification of similarities and differences, generalizations, and classifications within the information landscape. Hence, this topic retains its profound relevance in contemporary education.

Introduction: In the first part of our review, we highlighted the significant role of the intestinal microbiome for the human body. Its functions can be broadly categorized into three main groups: protective, metabolic, and immune system stimulation. The effectiveness of these functions depends on changes in the specific composition of the human microbiome, influenced by environmental conditions, living conditions, human nutrition, climate, genetics, and other factors.
The objective of this work is to provide guidance for doctors, higher education students, and medical interns in understanding the modern intricacies of microbial metabolism in the human gastrointestinal tract. This understanding will enable them to make informed decisions regarding the prescription of microbiome indicators for patients, as well as their subsequent interpretation and correction.
Materials and methods. Materials and Methods: We reviewed 61 international literature sources from databases such as PubMed, Scopus, and Google Scholar. The search was conducted electronically, and only English-language studies were included.
Results. For an objective assessment of the numerous data obtained by using the latest diagnostic methods, scientists have proposed indicators that for convenience are considered in the form of known ratios: Firmicutes / Bacteroidetes, Prevotella / Bacteroides, Fusobacterium nucleatum / Faecalibacterium prausnitzi. The ratio between Firmicutes/Bacteroidetes is the percentage value of the first (Firmicutes) divided by the percentage value of the second (Bacteroidetes) can range from infinity to zero. This ratio usually ranges from 0.1 to 10. The Prevotella/Bacteroides ratio varies widely and depends on gastronomic preferences, metabolic features, and concomitant pathologies. In turn, significant fluctuations in Prevotella /Bacteroides have signs of dysbiosis, which directly correlates with numerous human pathologies. A shift in the ratio of Fusobacterium nucleatum / Faecalibacterium prausnitzii towards the former, according to scientific studies, can be considered one of the screening indicators of early colorectal cancer.
Conclusion. When using ratios and markers to evaluate the homeostasis of the gut microbiota and make a diagnosis, it is important to consider not only the intricate relationship between the microflora and the human body, but also the nuances of metabolism within the microbial community. Both aspects are currently undergoing study with revolutionary methods and modern systems, which will ultimately contribute to a deeper understanding of these processes.
SLEEP QUALITY AND AVOIDANCE BEHAVIOR IN COMBATANTS WITH POST-TRAUMATIC STRESS DISORDER
Authors: Boiko D.I. , Mats O.V. , Shkidchenko O.I.
Published: May 2024

Introduction. Post-traumatic stress disorder (PTSD) is often characterized by various symptoms that result in behavioral changes in patients, among which sleep disturbances and avoidant behavior are commonly observed. However, despite evidence indicating a complex bilateral relationship between emotions and sleep, only few studies have explored the associations between sleep disturbances and avoidant behavior in the context of PTSD.
The aim of the study is to assess the severity of avoidant behaviour and insomnia in combatants with posttraumatic stress disorder.
Materials and methods. We conducted a clinical study of 45 combatants who were divided into 2 groups: group 1 (n=24) included combatants with PTSD; group 2 (n=21) consisted of combatants without PTSD. The Pittsburgh Sleep Quality Questionnaire was used to analyse sleep quality, namely subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, sleep medication use, and daily dysfunction. Avoidance behavior was measured using a multidimensional experience avoidance questionnaire.
Results. We found that group 1 demonstrated worse subjective sleep quality (p=0.002), longer sleep latency (p<0.001), lower sleep efficiency (p=0.019) and more severe sleep disturbances (p<0.001). There were no statistically significant differences between the groups in terms of sleep duration, severity of sleeping pills use, and daily dysfunction. The overall severity of sleep quality disorders was higher in group 1 compared to group 2 (p<0.001). Avoidance behavior (p=0.007) and repression and denial (p<0.001) were more pronounced in group 1 compared to group 2. At the same time, group 1 had lower stress endurance (p<0.001). The overall level of experiental avoidance in group 1 was higher than in group 2 (p<0.001). Numerous associations between sleep quality characteristics and experiental avoidance were found as well.
Conclusions. The study has revealed that combatants with PTSD have more pronounced manifestations of behavioural avoidance, repression and denial, as well as a lower level of stress endurance. At the same time, combatants with PTSD demonstrate a deterioration in the subjective quality of sleep, a decrease in its effectiveness and an increase in the severity of its disturbances. It has been found that avoidance behavior in combatants has numerous connections with the characteristics of sleep quality that may be suggested as a potential factor for improving psychotherapeutic interventions.
CHANGES IN CIRCADIAN CHARACTERISTICS OF PATIENTS WITH PARKINSON DISEASE AFTER CORRECTION OF POOR SLEEP QUALITY USING MELATONIN: AN OPEN-LABEL CONTROLLED RANDOMISED TRIAL
Authors: Shkodina A.D.
Published: May 2024

Introduction. Recent studies are increasing the amount of evidence suggesting that the circadian system is disrupted in Parkinson's disease that can lead to poor sleep. Currently, international guidelines for managing non-motor symptoms of Parkinson's disease do not have recommendations with proven efficacy, but only methods with potential benefit. Two of the most widely available methods for correcting poor sleep quality in patients with Parkinson's disease in Ukraine are sleep hygiene training, also known as somnoeducation, and melatonin administration.
The aim of the study is to compare the state of circadian characteristics before and after the correction of poor sleep quality in patients with Parkinson's disease in the context of sleep hygiene and an integrated approach with the implementation of chronotherapy using melatonin.
Materials and methods. We conducted a clinical trial at the Centre for Patients with Parkinson's Disease and Other Neurodegenerative Diseases, which included 34 patients with poor sleep quality who were randomised into 2 groups: group 1a (n = 17) consisted of patients with Parkinson's disease who followed sleep hygiene rules and received chronotherapy; group 1b (n = 17) involved patients with Parkinson's disease who followed sleep hygiene rules but did not take any medications to improve sleep. Circadian characteristics were analysed using the Munich Chronotype Questionnaire.
Results. Our study has found that the correction of poor sleep quality by introducing sleep hygiene into the treatment process of patients with Parkinson's disease demonstrates a shift in the time of sleep onset and mid-sleep to earlier, accompanied by a shift in chronotypes towards earlier, as well as an increase in sleep duration against a decrease in the time spent in bed, which led to an increase in the average actual sleep efficiency. At the same time, melatonin supplementation helps to reduce sleep latency in Parkinson's disease.
Conclusions. Adherence to sleep hygiene recommendations contributes to changes in circadian characteristics and improves sleep efficiency in patients with Parkinson's disease, regardless of melatonin administration. Additional use of melatonin to correct the quality of sleep for 1 month is accompanied by a reduction in the sleep latency period.

Published: May 2024

Introduction: The study focuses on the importance of maintaining oral hygiene, especially in wearers of fixed dental bridge. The impact of inadequate oral hygiene care on the development of dental diseases and the necessity for developing effective methods for its assessment are examined.
Research objective: The aim of this study is to refine the fluorescent diagnostic method in orthopedic dentistry and to develop an index for assessing the hygienic status of natural teeth and fixed dental prostheses through an in vivo experiment. This method is intended to improve the diagnosis of oral conditions in wearers of fixed prostheses, ultimately enhancing the quality of their orthopedic treatment.
Materials and methods: The study is based on the application of fluorescent diagnostics using Rhodamine B dye, which, when exposed to ultraviolet light, allows for the detection of dental deposits. The technique involves treating the surfaces of teeth and prostheses with a special solution that enhances the visibility of dental plaque under ultraviolet illumination.
Research results: The experimental results demonstrated the high efficiency of the fluorescent method in detecting dental deposits both on the enamel of natural teeth and on the ceramic surface of fixed dentures. The digital analysis method allows for obtaining specific graphical indicators of the biofilm area, enhancing the relevance of an individual approach.
Conclusions: Conclusions: The experimental study confirmed the high efficiency of the refined fluorescent method for assessing the hygienic status of the oral cavity, applicable to both natural teeth and fixed orthopedic constructions. This technique enables accurate assessment of hygiene status, facilitating effective prevention of dental diseases and optimization of treatment procedures.

OSTEOGENESIS AND BONE RESORPTION IN PATIENTS WITH POSTOPERATIVE MANDIBULAR BONE DEFECTS DURING INFLAMMATORY PROCESSES
Authors: Khattu V.V.
Published: May 2024

Tooth extraction has long been the most common surgical procedure. Preserving the height of the alveolar ridge after extraction is crucial for further replacement of the missing tooth, including through dental implantation. This study aimed to assess the effect of cryopreserved placenta and quercetin on bone formation and osteoresorption markers in oral fluid. Ninety patients who underwent lower tooth extraction due to inflammation participated in the research. They were divided into three clinical groups of 30 each: the first group received cryopreserved placenta after extraction, the second group received combined therapy of cryopreserved placenta and quercetin, and the third (control) group underwent standard tooth extraction. Osteocalcin and matrix metalloproteinase-8 levels in the oral fluid were measured on days 1, 10, 20, 30, 90, and 180 after extraction for all groups.
Antagonism between "osteocalcin" and "matrix metalloproteinase-8" was observed in the oral fluid during reparative osteogenesis. However, statistically significant changes in this marker were noted earlier in the observation period and were more pronounced, possibly due to local changes predominating. This suggests activation of bone tissue resorption processes in the early stages of the study and osteogenesis in the later stages of observation. The least dynamic changes in the studied indicators were observed when cryopreserved placenta was used in combination with quercetin treatment.
