Abstract:
Relevance. Temporomandibular joint dysfunction is one of the most widely spread and common disease nowadays. It includes disorders on different levels of whole body and multi symptom as clinical manifestation. There is still less of evidence in ethiopathology of Temporomandibular dysfunction(TMD).Objective. The research aimed to find new etiological factors impacting the formation of TMJ, recorded growth and developmental disorders of the facial skull in the experimental group. Materials and methods. The sample group consisted of 59 patients. The experimental group included 38 patients with lateral joint displacement; the control group included 21 patients. Subjects were examined with functional probes, occlusion diagnosis with articulation paper Baush 200,100,8 microns, cephalometryc analysis by Grummons, computed tomography of temporomandibular joint, licensed software application Planmeca Romexis Viewer, statistical analyses with program IBM SPSS Statistic Base v.22.Results. 91.6% of patients with dentofacial deformities of the maxilla (ddm) also have TMJ with lateral displacement of the articular heads of the mandible. Patients without maxillary dentofacial deformities experience lateral displacement of the articular heads with a frequency of 8.7% and probable risk of 10.5 (95% CI 2.79-39.8). Patients in 1group (63,16%) experiences asymmetric inclination of the angles of the right and left upper jaw and occlusal plane around tooth number 6 and 7, 79.94% of patients in the experimental group recorded a displacement of the mandible

Abstract:
The obtained results created a theoretical basis for optimizing the tactics of pregnancy management in such patients by applying a pathogenetically sound set of treatment and prevention measures. The proposed complex includes assessment of risk factors, additional examinations, monitoring of the condition of the pregnant woman and fetus, treatment measures to prevent placental insufficiency and reduce the negative effects of hyperimmune response (aspirin, dipyridamole, progestogens, intravenous immunoglobulin, vitamin D).To test the effectiveness of the proposed set of treatment and prevention measures, 80 pregnant women were selected after influenza, transmitted in early pregnancy, with a high risk of placental dysfunction. Patients were randomly divided into 2 groups: 40 women whose pregnancies were performed according to optimized tactics (main group) and 40 women (comparison group) whose pregnancies were managed according to the clinical protocols of the Ministry of Health.Testing the effectiveness of the proposed set of measures showed its positive effect on hormonal function of the placenta (normalization of progesterone and estradiol levels), immune status (reduction of NK-cytotoxicity, balance of cytokine profile), elimination of vitamin D deficiency and reduction of procoagulation potential of the hemostasis system.Creating favorable conditions for the development of gestation has reduced the incidence of placental insufficiency by almost 2 times to 35.0% vs. 62.5%. Against the background of the recommended tactics of pregnancy after influenza, the frequency of complications of pregnancy, disorders of the fetus and newborn has decreased significantly.

Abstract:
The purpose of the study: to evaluate the effectiveness of the proposed set of preventive measures for pregnant women after ART with a high risk of preeclampsia. Material and methods. To test the effectiveness of the proposed set of prophylactic measures, 60 pregnant women after ART were selected, which were randomly divided into 2 groups: 30 women who received the recommended complex (main group) and 30 women (comparison group), whose preeclampsia was prevented by order of the Ministry of Health. № 417 "Guidelines for the provision of outpatient obstetric and gynecological care." Results. The use of the recommended measures improves lipid metabolism (significant reduction of triglycerides and low density cholesterol), eliminates vitamin D deficiency, balances the cytokine profile (reduction of proinflammatory focus), reduces the prothrombotic potential of the hemostasis system (reduction of D-dimer and background marker damage). Improving the general condition and the use of psychotherapy can reduce the manifestations of vegetative-vascular dystonia, anxiety and improve quality of life. Such changes provide a more favorable background for the development of gestation. The incidence of preeclampsia decreased by 43.8% (from 26.7 to 15.0%), and mainly due to early preeclampsia, the incidence of which decreased by 78%, no cases of severe preeclampsia were reported. The frequency of placental insufficiency, fetal distress and growth retardation is reduced. The frequency of birth of children in a state of asphyxia is reduced by 2 times (up to 20.0 vs. 46.7%), severe asphyxia is not observed. Significantly lower and the frequency of violations of the period of neonatal adaptation (30.0 vs. 53.3%). Conclusions. The use of treatment and prophylactic complex to prevent preeclampsia in pregnant women after ART can improve a woman's homeostasis, balance vegetative-vascular regulation, reduce the incidence of preeclampsia by 43.8% (from 26.7 to 15.0%) and other complications of pregnancy and childbirth, improve perinatal outcomes. Proven medical, social and economic efficiency of the developed complex allows to recommend it for implementation in medical practice.

Abstract:
Разнообразные исследования последних десятилетий показали, что мелкие пылевые частицы могут представлять серьезную опасностью для здоровья, способствуя развитию респираторных и сердечно-cосудистых заболеваний. Выявлены потенциальные связи между вероятностью возникновения таких заболеваний, как хроническая обструктивная болезнь легких (ХОБЛ), астма, рак легких, с концентрацией пыли в воздухе. Есть корреляционные данные, свидетельствующие о том, что при увеличении ПДК пыли в воздухе всего лишь на 50 мкг / м3, приводит к увеличению смертности на 1-8 %. Твердые пылевые частицы оказывают существенное влияние на жизнь растений и животных. Многие промышленные, экспериментальные и медицинские процессы могут быть безопасно осуществлены только при определённых значениях концентрации пылевых частиц в воздухе: например, пыль, состоящая из твердых частиц размером менее 850 мкм, находящихся во взвешенном или осевшем состоянии в газовой среде, способна к самостоятельному горению и взрыву в воздухе. Такая пыль классифицируется как горючая пыль и, при определенных концентрациях, может стать причиной несчастных случаев на производствах, связанных со взрывами пылевоздушных смесей. Создание автоматизированной системы, способной контролировать запылённость воздуха в различных производственных помещениях является актуальной задачей. Данная работа посвящена созданию подобной системы, объединяющей в себя необходимое количество датчиков пыли, связанных между собой в беспроводную сеть, позволяющую управлять процессом измерения и фиксированием результатов измерения каждого конкретного датчика.

Abstract:
The increase in the cost of energy and the appearance of gases of various qualities led to the fact that calculations in the gas industry began to be made by measuring thermal energy. To this day, in Georgia, the calculation of the amount of natural gas when paying for the used gas is in cubic meters. As for the study of processes and parameters in the Georgian gas sector, it turned out that these processes are clearly stochastic. Therefore, the purpose of the work is to develop criteria for the interchangeability of natural gas, in particular, a diagram of the interaction between the Wobbe index in total proportions of propane and nitrogen equivalent for the Georgian gas market, based on stochastic processes. Thus, for the first time, an original methodology for plotting the Wobbe Index (calorific value) of interchangeable natural gases supplied to Georgia was developed.

Abstract:
The need to develop a system of rehabilitation programs for various stages of medical care providing to children with type 1 diabetes mellitus (DM) is due to a significant increase in the number of children with diabetes mellitus (DM) in recent times, a severe course of the disease, insufficient effectiveness of treatment and the absence of out-of-hospital rehabilitation of children's patients. Further development of rehabilitation programs for children and adolescents with Type 1 diabetes, basic awareness of the patient and his family regarding the disease and treatment methods is required. Despite the fact that a significant number of scientific studies are devoted to the problems of DM, there are difficulties in introducing an existing innovative product due to its isolation, diversity, organizational and other barriers in the process of transfer to real clinical practice.

Abstract:
Introduction. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by various manifestations and clinical course, many aspects of the etiology and pathogenesis of which remain unclear. Recently, the interest of researchers in studying the role of cytomegalovirus (CMV) and Epstein - Barr virus (EBV) has been growing in the occurrence and course of a number of human diseases due to their ability to affect almost all organs and systems of the body, causing the formation of latent, active or chronic infection, which can often cause temporary disability, disability or even death, however, for the patients with SLE, despite the possibility of approaching the difficult problem of diagnosis and treatment of this disease, this issue is given insufficient attention, as evidenced by isolated studies.The aim of the study. Detect cytomegalovirus and Epstein - Barr infection in patients with systemic lupus erythematosus and its dependence on gender and age of patients. Materials and methods of research. The study involved 120 patients (15 men (12.50%) and 105 women (87.50%) aged 18 to 69 years with SLE, who were in the rheumatology department of the Communal Non-Commercial Enterprise of the Lviv Regional Council "Lviv Regional Clinical Hospital" in 2014-2019. To diagnose CMV and EBV infection by enzyme-linked immunosorbent assay, antibodies of IgM and IgG to viruses were detected in blood serum, and viruses were detected by polymerase chain reaction. According to the results of virus detection, formed groups of the patients, namely: patients with active CMV infection, active EBV, active CMV and EBV, without active CMV and EBV. All patients with SLE included in the study were subsequently stratified by age according to the classification of the World Health Organization (2015), according to which the following age limits were determined: young age, middle-aged, elderly, senile. Statistical analysis was performed on a personal computer in MS Excel and Statistica 6.0 using descriptive statistics. The frequency of cases of active CMV and EBV infection was calculated mathematically by the binomial coefficient of I. Newton. Research results and their discussion. We found in the vast majority of patients with SLE (117 patients, 97.50%) increase in the titer of specific antibodies to CMV. Only in 3 patients (2.50%) the titer of antibodies to this virus was within normal limits. Analyzing the frequency of EBV infection in patients with SLE, we recorded an increase in the titer of specific antibodies to the virus in 119 patients (99.17%). Among the examined patients with SLE in all (100.00%) found an increase in the titer of antibodies to CMV and / or EBV, of which 97.50% - infected with CMV and 97.17% - infected with EBV. The active phase of CMV and / or EBV infection was detected in 54.17%, of which 23.33% - active CMV infection, 17.50% - active EBV infection and 12.50% - a combination of active CMV and EBV infection simultaneously, which indicates a high frequency of CMV and EBV infection in patients with SLE and reflects the urgency of the problem of diagnosing herpesvirus infection in them. We found that activeCMV, EBV infections and their combinations are present only in women (64 patients, which is 60.96% of the total number of women with SLE), of which 28 patients (26.67%) there was only active CMV infection, in 21 patients (20.00%) - only active EBV infection and in 15 patients (14.29%) – combination of active CMV and EBV infection. 41 women (39.05%) and all (100.00%) men were not found to have active CMV and EBV infection, which indicates that men at the time of the survey were significantly more likely to have this infection in the integration phase. The most frequently active EBV infection was detected in patients with SLE of young age (17 cases, 24.64%), and in middle-aged patients 3 cases (6.52%) were recorded, which indicates a significant (p

Abstract:
Enterocolitis disorders caused by Clostridioides difficile infection still remain a serious health problem in the world. In many countries CDI is officially considered a nosocomial infection that causes considerable economic losses, including diagnostic and treatment costs. According to the existing data, C. difficile is the main agent causing antibiotic – associated diarrhea and the main etiologic factor of the pseudomembranous colitis (PMC) that often develops in case of complete destruction of the intestinal flora due to the use of antibiotics or chemotherapeutic agents. There is no official registration of CDI in Ukraine, therefore the official incidence and lethality rates are absent. At this time, the problems of development and improvement of selective nutrient mediums and quick, affordable bacteriological methods of C. difficile isolation are especially relevant.The comparative study of the efficacy of the known commercial nutrient mediums for isolation of toxin-producing strains of C. difficile was carried out and composition of a new, original selective nutrient medium was proposed. Unlike existing analogs, the proposed nutrient medium is suitable for the simultaneous isolation of the agent from the clinical material and detection of toxin-producing properties due to its high growth properties, optimal transparency and density.
