The article presents a verification technique for solving the inverse geometric problem of magnetostatics in a soft magnetic ferromagnet plate. The technique involves solving a number of direct problems, in which the shape of the defect obtained by solving the inverse geometric problem of magnetostatics is used as a first approximation, and then increasing or decreasing the depth of the defect without changing the shape of the boundary surface — comparing the topographies of the magnetic field components obtained during measurements above the plate surface and calculated (as a result of solving the direct problem) at the same points of the components of the magnetic stray field from the reconstructed three-dimensional defect. As a result of applying the technique, the geometric parameters of the defect under study can also be refined. Obtaining the initial conditions for solving the inverse problem and solving direct problems of magnetostatics is carried out using the finite element method in the ELMER program. The technique works with one-sided access to any surface of the plate (a defect-free surface or a surface with a defect).

Published: October 2024

Aims: The aim of this study is to examine the relationship between orthorexia nervosa (ON) and social appearance anxiety (SAA) and to investigate the effects of these variables on healthy lifestyle behaviors (HLB) in young adults aged 18-30 years. Methods: A total of 408 young adult male and female volunteers, with a mean age of 21.7±2.95 years, participated in this study. A structural model was proposed to examine the effects of SAA and ON on HLB. To assess how well the study variables represented the underlying components, we first evaluated a confirmatory measurement model. Subsequently, we analyzed a structural model that allowed for the examination of multiple regression equations involving several dependent variables. Results: SAA had a negative influence on HLB (std β=-0.673; t-value=-8.425), a significant negative relationship between ON, HLB was also promoted (std β=-0.554; t-value=-9.388). It was determined that there is a positive correlation between SAA, ON which is statistically significant (correlation coefficient=0.830; t-value=10.244). Conclusion: It is concluded that the individuals with high social appearance anxiety do not adopt healthy lifestyle behaviors and are more prone to orthorexia nervosa.

While the rate of UC patients has slightly decreased to 98 (61.6%), 401 (58.5%) and 374 (53%) frequency of CD patients has increased to 61 (38.4%), 284 (41.5%) and 331 (47%). Over the course of three decades, there were more UC patients than CD patients, however proportion of UC/CD has been continuously decreased (1.61, 1.41 and 1.13) for three decades respectively.
Conclusion: Our study showed that the frequency of UC and CD has significantly increased during the previous three decades in non-endemic era for IBD. While the frequency of UC patients has slightly decreased, that of CD patients has steadily increased over the past three decades. Although the use of biologics has significantly increased, proportions of the major abdominal surgeries and colectomies has not prominently changed.

одним із найпоширеніших неінфекційних захворювань у світі стає надмірна маса тіла та ожиріння особливо у дітей. Захворюваність на ожиріння постійно зростає і призводить до розвитку ускладнень та супутніх захворювань.  Розлад імунологічного гомеостазу проявляється у дітей з даною патологією зростанням частоти отоларингологічних захворювань, одним з яких є патологія мигдаликів глотки. Мета дослідження: визначити особливості перебігу захворювань глотки у дітей з надмірною вагою тіла та ожирінням до операції на глотковому і піднебінному мигдаликів та в післяопераційному періоді. В дослідженні приймали участь 69 дітей з гіпертрофією мигдаликів глотки, які були розподілені на 3 групи в залежності від індексу маси тіла: з надмірною масою тіла (1-а група), з ожирінням (2-а група) та нормальною масою тіла (3-а група). Всі пацієнти пройшли анкетування за допомогою тесту: Pediatric Throat Disorders Outcome Test (Т-14) перед та після хірургічного лікування (тонзилектомії, тонзилотомії, або аденотонзилотомії) через 3 та 6 місяців. Крім анкетування  пацієнтам було проведено ретельне отоларингологічне обстеження. Передопераційне обстеження показало, що середня кількість балів показників скарг пацієнтів відповідно Т-14, була найменшою  у пацієнтів 3-ой групи, найбільшу кількість балів показало тестування 2-ої групи (p<0,001). Через 6 місяців після операції статистично значущі співвідношення серед груп пацієнтів по середній кількості балів не змінились: кращий в 3-ій групі – 1,60 (p<0,05), найгірший в групі пацієнтів з ожирінням – 14,0 (p<0,05),  в 1-ой групі – 7,38 (p=0,05). В більшості випадків – 88,9% випадків у пацієнтів з ожирінням зберігались скарги на хропіння, в 77,8% випадків - нерегулярне дихання під час сну,  в 44,4% - періодичне дихання через рот, в 27,7% - проблеми з апетитом, в 22,2% - рецидив гіпертрофії піднебінних мигдаликів,  секреторний середній отит  рецидивуючого перебігу в 22,2% випадків також. В 1-ій групі через 6 місяців після операції пацієнти продовжували скаржиться на голосне хропіння в 38,5% випадків, на апное -  26,9%, проблеми з апетитом -  42,3%, короткочасні інфекції горла – 61,5%, рецидив гіпертрофії піднебінних мигдаликів -15,4%. Що стосується результатів лікування пацієнтів з нормальною вагою, то лише в 4,0% випадків спостерігались скарги на періодичне хропіння, біль в горлі та рецидивуючий секреторний середній отит.

початок широкомасштабного вторгнення в Україну у 2022 році зробив очне відвідування навчальних закладів небезпечним і не завжди можливим, що спонукало повернення до дистанційної форми, запровадженої у 2020 році під час початку пандемії COVID-19. Але у воєнний час заняття часто доводиться переривати для переходу в укриття, а зв’язок може бути нестійким. Все це спонукає до пошуку нових методів дистанційного навчання. Лікарям-слухачам, які знаходилися на циклі серцево-легеневої та церебральної реанімації, був запропонований формат текстової рольової гри у чаті месенджера Telegram. Концептуально цей формат не відрізняється від очних симуляційних сценаріїв: викладач дає слухачам сценарій та залежно від їх дій описує реакції пацієнта. Відмінністю є те, що без доступу до манекена та без можливості відпрацювання у реальному часі лікарі-слухачі описували свої дії у текстовому вигляді. У кожному сценарії брали участь три слухачі: один у ролі «лікаря» (лідер команди), двоє – у ролі «медсестер». Роль «лікаря» передбачала лікарські маніпуляції, організацію роботи команди та делегацію завдань «медсестрам», діагностику та призначення лікування. Роль «медсестри» передбачала виконання призначень лікаря та повідомлення про можливі проблеми. Решта групи спостерігала за відпрацюванням сценарію. При допущенні грубих помилок у протоколі викладач зупиняв сценарій та пропонував усій групі поміркувати та обсудити, чи все виконано вірно. У слухачів був час звіритися з конспектом лекції та клінічними протоколами. Шляхом дискусії слухачі самі обирали вірний варіант, після чого сценарій продовжувався. Лікарі-слухачі виявили високу мотивацію та зацікавленість до заняття у такому форматі. При поверненні до аудиторії слухачі, які брали участь у рольовій грі, показали значно кращий результат, ніж ті, які лише читали матеріали з теми та/або прослухали лекцію. Корекції потребували лише практичні навички на манекені. Наш перший досвід використання такого формату показав, що за відсутності можливості проведення симуляційного заняття аудиторно текстова рольова гра є більш ефективною формою навчання, ніж традиційне опитування.
Anatomical and phytochemical study of Ocimum basilicum L. leaves of two popular varieties in Ukraine

оne of the important sources of flavonoid phytonutrients is basil (Ocimum basilicum L.). Vegetative and generative organs of which have essential oils, in particular 1,8-cineole, estragole and eugenol, ascorbic acid, a rich pigment complex, as well as polyphenolic compounds with antioxidant effects. Basil realizes its antioxidant potential through anthocyanins in varieties with purple leaves and flavonoids in varieties with green leaves. The level of their accumulation, as well as other biologically active substances, depends on the variety to which the plant belongs, the degree and spectrum of illumination, soil moisture, and mineral nutrition (Priss OP, et al., 2019; Joshi RK, 2014; Trichopoulou, et al., 2000). That is why our attention was drawn to two of the most popular basil varieties in Ukraine: "Dolly" with green leaves and "Rosie" with purple leaves. Our research was focused on morphological, anatomical and phytochemical studies of O. basilicum leaves of the above-mentioned raw materials. To realize this goal, microscopy was performed using State Pharmacopoeia of Ukraine methods. Groups of biologically active substances were determined by standard qualitative reactions and the procedure was carried out using extracts or by applying directly to the sections. It was found that O. basilicum chanterelles of "Dolly" and "Rosie" varieties have a number of common and distinctive features. Both varieties of O. basilicum are characterized by the presence of dorsoventral, amphistomatic leaves, diacytic stomatal apparatus and biserial glands. The leaves differ in color, shape of the leaf blade margin, outlines of the upper epidermal cells, presence of idioblast cells with anthocyanins in the "Rosie" variety, and values of stomatal indices. The stomatal index is 27.5±2.3% for the  "Dolly" variety and 25.4±2.5% for the "Rosie" variety. It was found that the leaves of O. basilicum varieties "Dolly" and "Rosie" contain such biologically active substances as anthocyanins, flavonoids, essential oil, triterpene saponins, especially expressed in the variety "Rosie" and tannins. The research results can be used in the development of a monograph on the raw materials of this species.

the treatment of COVID-19 remains a challenging issue worldwide due to the huge economic losses to society as a result of the disease's widespread prevalence, peculiarities of its course and complications of its development. The purpose of the work was comparative analysis of the effectiveness of new treatment regimens for outpatients with mild COVID-19. 64 medical charts of outpatient diseases with a mild course of COVID-19 were studied. Depending on the treatment regimen used, all patients were divided into two groups that received inhaled ACEs or antiviral therapy with the combination drug nortrelvir/ritonavir. The efficacy of each pharmacotherapeutic alternative would be determined on the basis of retrospective data for the timeframe of normalisation of clinical and laboratory parameters. A rule was established that the set of all clinical and laboratory parameters in the normal range is considered as a clinical endpoint. It was found that the use of ACC treats the disease until the rapid disappearance of clinical symptoms, especially in the first treatment, which works on its rapid therapeutic effect in the initial stages. Nirmatrelvir/ritonavir has also been shown to be effective in reducing symptoms, but its effect is incremental, reaching full relief slightly later than in ACC. Modeling of the dynamics of reaching the clinical point of elimination of all clinical symptoms indicates a pharmacoeconomic advantage of the use of ACC over nirmatrelvir/ritonavir, if the additional costs of treatment do not exceed the cost of three days of treatment.

Authors: Temirova Olena , Marchuk Daria
Published: October 2024

the management of diarrhea represents a prevalent issue within the realm of healthcare. Rifaximin is recommended to treat traveler's diarrhea and irritable bowel syndrome. At the same time, it is important to rationally use an antimicrobial drug to prevent the development of antimicrobial resistance. Aim: to evaluate the role of pharmaceutical care in using rifaximin to treat diarrhea, based on a questionnaire. A questionnaire survey was done among 55 pharmacy professionals and 42 pharmacy visitors regarding the dispensing and use of rifaximin for diarrhea treatment. The survey of pharmacy visitors revealed that rifaximin was used for the treatment of small intestinal bacterial overgrowth syndrome (32 cases), traveler's diarrhea (7 cases), and irritable bowel syndrome with diarrhea (3 cases). Patients did not undergo stool culture before rifaximin prescription, which could have prevented antimicrobial resistance and ruled out other causes of diarrhea. It was found that 14% of respondents reported improvement the next day, while 83.3% reported improvement within three days. Pharmacists can educate visitors about the importance of completing the treatment course. Five percent of respondents reported nausea as an adverse reaction. Pharmacists dispensed rifaximin for the treatment of diarrhea in adults almost three times more often than in children. The tablet form of the drug was used in 94.5% of cases, while the oral suspension was used in 5.5% of cases. The majority of pharmacy visitors (89.0%) received rifaximin with a doctor's prescription, and 10.9% without a prescription, which emphasizes the importance of pharmaceutical care to prevent irrational use of the drug. The results of the study show that 92.7% of pharmacists provide recommendations on the safety of rifaximin use, and 78.2% recommend abstaining from alcohol during treatment. Only 21.8% of pharmacists warn about the possible staining of urine, which can cause concern for patients. The majority of pharmacists (89.1%) systematically ask women about possible pregnancy, which indicates their awareness of safe pharmacotherapy. Pharmacists also clarify the simultaneous use of rifaximin with other drugs: 32.7% ask about taking oral contraceptives, 7.3% –  antiarrhythmic drugs, and 3.6% – warfarin. mailto:https://meshb.nlm.nih.gov/record/ui?ui=D002648Pharmacists can enhance the effectiveness of rifaximin treatment by preventing its uncontrolled use, emphasizing the importance of completing the treatment course and informing about possible adverse reactions. When providing pharmaceutical care to visitors taking rifaximin, pharmacists should educate them about potential changes in urine color. Additionally, pharmaceutical workers advise women taking oral contraceptives to use additional contraceptive methods while taking rifaximin.
