Authors: Kaya Gökhan , Dizman Didem , Su Küçük Özlem
Published: October 2024

Aims: The systemic and respiratory clinical manifestations of coronavirus disease 2019 (COVID-19) include fever, cough, sneezing, sore throat, rhinitis, dyspnoea, chest pain, malaise, fatigue, anorexia, and headache. Moreover, cutaneous manifestations have been observed in 0.2% to 20.4% of cases. This investigation further explores the dermatological manifestations associated with COVID-19 and reactions induced by its pharmacological treatments. Conducted at a university hospital, the study examined 841 patients and identified skin manifestations in 1.5% of cases. It differentiates between symptoms directly attributed to the viral infection and those arising from treatment, highlighting the need for clinical vigilance and adaptability in managing these manifestations. COVID-19 has been linked to a wide range of clinical symptoms, extending beyond the well-known respiratory effects to include various dermatological manifestations. These manifestations, which range from mild rashes to severe conditions like vasculitis, may complicate diagnosis and management, particularly when similar symptoms are induced by therapeutic drugs used in COVID-19 treatment.
Methods: This cross-sectional study included 841 patients treated in the COVID-19 outpatient and inpatient units of the university hospital between March and May 2020. The assessment involved clinical examinations and telemedicine consultations, focusing on differentiating between viral and drug-induced dermatological reactions.
Results: Dermatological manifestations were observed in 1.5% of the 841 patients. Direct virus-related skin changes were noted in 1% (n=8) of patients, including maculopapular eruptions (50%, n=4) on the face and trunk, trunk-localized urticaria (25%, n=2), and purpuric lesions (12.5%, n=1) on the lower extremities. Drug-induced dermatological reactions were identified in 0.5% (n=5) of patients, featuring conditions such as bullous drug reactions, psoriasiform drug eruptions, hypertrichosis, and urticaria.
Conclusion: These findings highlight the complex interplay between COVID-19 and its treatment, where both the virus and pharmacological agents can trigger significant dermatological reactions. The need for healthcare providers to consider both viral and drug-induced factors in the diagnosis and management of skin manifestations in COVID-19 patients is underscored. Further studies are essential to refine treatment protocols and reduce adverse dermatological outcomes.
Detection of virulence factors of Enterococcus faecalis isolated from the urinary system and evaluation of antibiotic resistance
Authors: Turan Deniz , Gürler Bülent
Published: October 2024

Aims: Enterococci, which are among the leading causes of nosocomial infections, are opportunistic pathogens and cause urinary tract infections most frequently. The frequency of isolation increases especially in patients with urinary system anomalies or urological interventions. Although various virulence factors play a role in the pathogenesis of infections caused by enterococci, cytolysin, hemolysin and enterococcal surface protein (ESP) are among the frequently investigated virulence factors. In this study; It was aimed to investigate the relationship between the presence of virulence factors and antibiotic resistance in Enteroccus faecalis (E. faecalis) strains isolated from urine samples, as well as the effect of urinary catheter use on these factors.
Methods: 100 strains isolated from urine samples sent to İstanbul University İstanbul Faculty of Medicine Medical Microbiology Laboratory and identified as E. faecalis with the VITEK 2 (biomerioux-France) GP identification kit were included in the study. Hemolysin and gelatinase, virulence factors, were determined phenotypically. The presence of the ESP gene was investigated by PCR using ESP11 and ESP12 primers. Antibiotic sensitivities were studied by disk diffusion and gradient strip methods, and the results were evaluated in accordance with CLSI and EUCAST recommendations.
Results: Antibiotic resistance rates were found to be 2%, 31%, 1%, 22%, 37% for ampicillin, norfloxacin, nitrofurantoin, high-level gentamicin (HLG) and high-level streptomycin (HLS), respectively, while no strains resistant to vancomycin, linezolid and tigecycline were detected. When evaluated in terms of virulence factors; It was determined that 82% of the strains produced gelatinase, 67% produced ESP, and 35% produced hemolysin. No virulence factor was detected in eight strains.
Conclusion: In our study, no significant relationship was found between the presence of virulence factors and antibiotic resistance and catheter application. However, since the most detected gelatinase and ESP are virulence factors that have the ability to colonize and form biofilms on abiotic surfaces, it is thought that minimizing catheterization practices may contribute to the prevention of UTIs that may develop with enterococci.

Published: October 2024

Aims: The objective of this study was to evaluate the color stability of five nanohybrid composite resins, including locally produced Turkish brands and an international brand, after exposure to staining and brushing simulations over time.
Methods: Five nanohybrid composite resins; Filtek Z550 (FLT), Dolgunn (DLG), RubyComp Nano (CMP), Nova Compo C (NVC), and Parion (PRN) were tested. Specimens underwent staining and brushing simulations designed to replicate clinical oral conditions. The staining process involved immersing the specimens in a coffee solution for 8 hours per day over a 10-day period to simulate short-term staining (t1), and for 12 days to simulate long-term staining equivalent to 1 year (t2). Brushing cycles were used to replicate the mechanical wear caused by daily oral hygiene practices. Color measurements were recorded at baseline (t0), after 10 days of staining (t1), and after 1 year of simulated staining and brushing (t2). Additional analyses were conducted using Energy-dispersive X-ray spectroscopy (EDX) and Scanning Electron Microscopy (SEM) to investigate structural and surface characteristics. Statistical analysis was performed using generalized linear models and two-way robust ANOVA to assess the significance of differences in color stability, with a significance level set at p
Вплив імплантації сферичних та асферичних інтраокулярних лінз на функціональні показники зору
Authors: Kochuhur Iryna
Published: October 2024

катаракта є одним з основних захворювань, що знижує гостроту зору та призводить до сліпоти, викликає значні труднощі та обмеження для пацієнтів у їх повсякденному житті. З кожним роком катаракта молодшає і все більша частина населення страждає на дану хворобу. Нині золотим стандартом хірургії катаракти є факоемульсифікація з імплантацією інтраокулярної лінзи (ІОЛ). Цей сучасний та ефективний метод лікування, вимагає ретельного підходу до вибору інтраокулярних лінз для максимізації результату та задоволення індивідуальних потреб пацієнтів. Важливим є не лише сама гострота зору пацієнта після операції, а саме якість його зору. Метою дослідження є проаналізувати та порівняти вплив імплантації сферичних та асферичних інтраокулярних лінз на функціональні показники зору               (гостроту зору, сферичні аберації та контрастну чутливість) у пацієнтів з віковою катарактою після хірургічного лікування. Дослідження проводилось на кафедрі офтальмології НМУ ім. О.О. Богомольця на базі КНП «Олександрівська клінічна лікарня м. Києва» та Медичного офтальмологічного центру «Зір 100%». Було досліджено 80 пацієнтів (80 очей) від 45 до 75 років з діагнозом вікова катаракта, яким було проведено хірургічне втручання – факоемульсифікація з імплантацією ІОЛ. У пацієнтів були відсутні будь-яка інша  патологія органа зору, важка соматична патологія. Пацієнти були поділені на 2 групи: 1 група – 40 пацієнтів (40 очей), яким була імплантована Alcon AcrySof Single-Piece (SA60AT) – сферична ІОЛ; 2 група – 40 пацієнтів (40 очей), яким була імплантована Johnson & Johnson Tecnis Symfony – асферична ІОЛ. Для прийняття участі у дослідженні всі учасники обов’язково підписували інформовану  згоду. Вимірювання функціональних показників зору               (гострота зору, сферичні аберації та контрастна чутливість) проводилось за 1 день до хірургічного втручання, через 7 днів та 1 місяць після операції. Згідно отриманих результатів, гострота зору у пацієнтів після імплантації асферичної ІОЛ була вища, ніж після імплантації сферичної ІОЛ, але ця різниця не є статистично значимою. Асферична ІОЛ статистично значимо зменшила післяопераційні внутрішні сферичні аберації до 50% порівняно зі сферичною ІОЛ і статистично значимо забезпечила на 10% вищу контрастну чутливість після операції. Таким чином, імплантація асферичної ІОЛ дала вищу контрастну чутливість в післяопераційному періоді, ніж імплантація сферичної ІОЛ. Тому, якість зору у пацієнтів була вища при імплантації асферичної ІОЛ.

Authors: Lazar Yehor , Mazur Anastasya , Myronova Olena , Romanenko Hanna
Published: October 2024

останнім часом дедалі ширше в діагностичну практику впроваджується радіонуклідна сцинтиграфія шлунково-кишкового тракту, яка дозволяє окрім якісних отримувати і кількісні параметри при різній його патології. В розвинених країнах динамічна езофагогастросцинтиграфія вважається «золотим стандартом» для виявлення функціональних порушень верхніх відділів травного тракту, які неможливо отримати іншими променевими методами. Незначне променеве навантаження порівняно з рентгенологічними методами  і неінвазивність дозволяє проводити це дослідження пацієнтам з будь-якою патологією верхніх відділів шлунково-кишкового тракту. Однак, на сьогоднішній день радіонуклідне дослідження верхніх його відділів є малодоступним методом в Україні, що пов'язано з дефіцитом спеціальної апаратури, радіофармпрепаратів та відповідних фахівців, здатних правильно інтерпретувати отримані результати. Враховуючи клінічні прояви та скарги пацієнтки К., 25 років, в радіологічному відділенні київської міської клінічної лікарні №18, яке розташоване на базі кафедри радіології та радіаційної медицини НМУ імені О.О. Богомольця була виконана динамічна езофагогастросцинтиграфія. Попередні інструментальні чи променеві методи дослідження пацієнтка не проходила. За результатами дослідження були виявлені зміни на сцинтиграфічному зображенні органу, а саме: відхилення стравоходу ліворуч на межі верхньої і середньої третини, звуження його в цій ділянці, затримка радіофармпрепарату в верхній частині. Спостерігались і кількісні зміни при комп’ютерній обробці результатів: збільшення езофагеального транзитного часу майже в 3 рази, зменшення кліренсу стравоходу і швидкості проходження препарату по ньому. З боку шлунку спостерігалась затримка надходження радіофармпрепарату до нього, а також із нього в кишківник. Враховуючи отримані результати для визначення причини вказаних змін, пацієнтку було направлено на дообстеження: фіброезофагоскопію, в результаті якої виявлена компресійна деформація середньої третини стравоходу, гастропатія еритематозна та дискінезія дванадцятипалої кишки; мультиспіральну комп’ютерну томографію органів грудної порожнини з контрастуванням ультравістом, в результаті якої було виявлене об’ємне утворення заднього середостіння, деструкція Th3, збільшення розмірів внутрішньогрудних лімфатичних вузлів; лабораторне дослідження крові, при якому встановлені нейтрофілія, еозинофілія, лімфоцитопенія, тромбоцитопенія, нормоцитарна анемія, підвищення активності ЛДГ і лужної фосфатази, підвищення ШОЕ, гіпергаммаглобулінемія та зниження рівня альбуміну; трепанобіопсія кісткового мозку з виявленням лімфоїдних клітин. В результаті дообстеження пацієнтці був встановлений діагноз класичної форми лімфоми Ходжкіна - лімфогрануломатоз ІІ стадії.

Published: October 2024

prevalence of cardiac rhythm and conduction disorders is increasing and associated with the growing amount of people of older age groups. The extended use of traditional electrocardiography (ECG) recorders is currently limited due to duration of the investigation, possible skin irritation and withdrawal of consent by the patients.  The aim:  evaluation of the frequency of arrythmia incidents in adult patients of different ages by assessing the patch monitoring results, and the impact of the monitoring duration on the possibility of diagnosis. Materials and methods: study included 1123 patients aged from 18 to 99 (599 women and 524 men), data about whom was collected in 2021-2022. ECG was recorded by the «Mawi Heart patch» – a single-use dual-channel device for continuous ECG recording for up to2 7 days. Results: the average ECG monitoring time was 81,03±18,5 hours or 3,37±0,7 days. The majority of the participants (74,35%) received the continuous 3-day ECG monitoring. Most rhythm disorders were recorded in the first 24 hours, but over the next 2 days, atrial fibrillation (AF) was detected in 7,66%, more often in men (48 participants, p=0,048) and with some differences in age groups. Starting above 50 years of age, the frequency of AF diagnosing on the first monitoring days is decreased and it is significantly statistically lower (61,11%, p<0,05). Three-day ECG monitoring is associated with a higher chance of detecting AF (OR=2,03; 1,53-3,02, p=0,031) regardless of gender, while the 5-day monitoring wasn’t as effective. The prolonging of the monitoring time increased the number of diagnosed supraventricular tachycardia (SVT) cases by 5,53% in men and 8,35% in women. The 3 days of monitoring are associated with a higher chance of SVT detection (OR = 4,18; 3,32–4,95, p=0,009). There is a direct correlation between SVT detection and the older age groups (r=0,53, p<0,05). SVT detection is higher in patients of 71-80 years old (OR = 2,71; 2,35–3,75, p=0,0041), and of 81-99 years (OR = 2,92; 2,56–3,49, p=0,0039). Conclusion: The frequency of arrhythmia detection, in patients referred to long-term patch monitoring, is high both for AF and SVT. The sex and age patterns for the prevalence of the described arrhythmias were statistically confirmed. The use of long-term ECG patch monitoring increases the chance of arrhythmia detection, primarily for older patients.

Behavioral copying is a key process in group actions, but it is challenging for individuals with Autism Spectrum Disorder (ASD). We investigated behavioral contagion, or instinctual replication of behaviors, in Krushinky-Molodkina (KM) rats (n=16), a new rodent model for ASD, compared to control Wistar rats (n=15). A randomly chosen healthy Wistar male (“demonstrator rat”) was introduced to the homecage of experimental rats (“observers”) 10-14 days before the experiments to become a member of the group. For the implementation of the behavioral contagion experiment, we used the IntelliCage system, where rats can live in a group of 5-6 rats and their water visits can be fully controlled. During the experiment, the demonstrator was taken out of IntelliCage for 24 hours of water deprivation and then placed back. As a result, a drinking behavior of the water-deprived demonstrator rat prompted activated behaviors in the whole group. Unlike the Wistar controls, KM observers showed fewer visits to the drinking bottles, particularly lacking inspection visits. The control group, in contrast, exhibited a dynamic, cascade-like visiting of the water corners. The proportion of activated observers in KM rats was significantly lower, as compared to Wistar ones, and they did not mimic other observer rats. KM rats, therefore, displayed an attenuated pattern of behavioral contagion, highlighting social deficits in this ASD model. This study suggests that measuring group dynamics of behavioral contagion in an automated, non-invasive setup offers valuable insights into social behavior in rodents, particularly for studying social deficits in ASD models.

People often use external tools to offload cognitive demands in remembering future intentions. While previous research has identified the causal role of metacognition in cognitive offloading, the neural mechanisms underlying this metacognitive control process remain unclear. To address this gap, we conducted a study with 34 participants using diffusion tensor imaging (DTI) to investigate how connections between brain regions support metacognition-driven cognitive offloading. Behaviorally, we confirmed that under-confidence in using internal memory to execute delayed intentions predicts a bias towards using external reminders. At the brain level we found that the fractional anisotropy (FA) of the fornix, a memory-related white matter tract connected to the hippocampus, positively correlated with the bias in setting up reminders. Additionally, the FA of the left uncinate fasciculus, which links the hippocampus to the prefrontal cortex and is involved in memory error monitoring, negatively correlated with deviations from optimal reminder use. Furthermore, the FA of the superior longitudinal fasciculus, a tract involved in metacognitive monitoring, moderated how confidence influenced the use of reminders. Taken together, our findings reveal a temporal-frontal neural circuit underlying metacognition-driven cognitive offloading, and provide new insights into the interaction between metacognitive monitoring and control.
Islam and Terrorism in the Middle East
Authors: Bílková Veronika
Published: October 2024

Some of the most crucial aspects linking Islam and terrorism in the Middle East are the focus of this essay. First, the ambiguity of the Sharia, the Islamic code of religious law, towards terrorism is discussed, a source of wide-ranging interpretations. Different ways of how terrorism has made its way throughout the history of the Muslim world are explored. Two examples are used to prove that terrorism has actually never traditionally been central to the spread of Islam, nor has it served any other Islam-related purpose. An analysis of the Islamic extremist groups of the Assassins and Kharijites reveals that it has always been minority factions that have used the weapon of terrorism to force their views onto the majority population. It is argued that two streams of thought lie behind modern terrorism by Muslims in the Middle East: nationalism and Islamism. The author shows that the first ideology was potent until the late 1970s, then to be overshadowed by the powerful concept of Islamism in the last twenty-five years of the 20th century. The author dismisses the claim that these two streams of thought and the violence they incite are Islam-specific. Instead, she makes the case that they can be linked to the major global ideologies of the time, i.e. the fight for national liberation and attempts by the South to counter the hegemony of the North. The final part of the essay explores the ways in which Muslim countries in the Middle East tackle terrorism. The author lists key universal and regional legal documents, adding a detailed analysis of the regional treaties by the Arab League (1998) and the Organisation of Islamic Conference (1999). Typical attitudes in Middle Eastern Muslim countries-such as the distinction made between terrorism and the struggle for national liberation, the role of the Palestinian cause, an effort to eliminate deeper motives for terrorist behaviour or the concern for uprooting 'state-sponsored terrorism'-are highlighted.

In modern gear mechanics, transmission mechanisms play a crucial role in converting the rotational motion of a driving shaft into the rotational motion of another shaft with varying angular speeds and torque. To achieve optimal designs for the next generation of transmission mechanisms, it is essential to develop mathematical models of their dynamic behavior, conduct computer simulations of the meshing geometry of key components, and visualize the operation of the mechanism. Despite the widespread use of involute gearing in mechanical transmissions, there is ongoing research into new types of gearing that offer advantages over traditional systems. The main challenges facing the industry include increasing the gear ratio in a single stage, enhancing load capacity, and improving efficiency compared to standard gear transmissions. This paper presents the results of mathematical and computer modeling, along with a comparative analysis of the eccentric-cycloid (EC) engagement with the involute gear transmission. Through analytical calculations, the energy-force parameters of the EC gearbox were determined, equivalent stresses and static deflections of transmission shafts were obtained. The paper includes the results of static analysis of elements of the new EC transmission, as well as an algorithm for computer modeling of contact stresses occurring in the engagement. Conclusively, by comparing contact stresses in traditional involute gear transmission, calculated using various analytical methods, with those in EC engagement determined through computer simulation, the advantages of the new transmission type and its potential application in mining equipment transmission mechanisms are highlighted.

Modular construction is a new method that uses standardized blocks to construct buildings quickly and efficiently. This approach can significantly reduce construction time and costs, as well as improve the accuracy and quality of work. One of the key aspects of modular construction is careful design and material selection to ensure that structures are durable and safe. The study presents an experimental evaluation of the strength of the floor slab of a volumetric block. The research methodology includes the creation of laboratory conditions to recreate real operational situations, as well as the application of modern methods of measurement and data analysis. The results obtained allow conclusions to be drawn on the strength characteristics of the floor slab, which showed that the experimental failure load exceeded the control failure load by 11%. The vertical deflections of the slab before failure did not exceed 8 mm, which characterizes the floor slab as having high stiffness. The information obtained is an important basis for designing and constructing buildings where volume block is used. The work significantly contributes to the efficiency of construction processes and provides more reliable structural performance, which is critically important in the field of construction industry and engineering solutions.
