Prevention of occupational laryngitis in teachers. Savushina I.V., Pavlenko O.I., Zos'ka Y.V. The number of people in need of phoniatric help is constantly increasing. People with voice problems are of working age. The object of researche: lowering risk of progression of vocal pathology based on a comprehensive system of management of teachers’ occupational risks. Hygienic, epidemiological, sanitary-statistical, in-depth medical examination method and mathematical-statistical methods were applied. Working conditions of teachers are characterized by complex effects of harmful production factors, which can reach 3 degree of 3 class of harmful work by intensity (according to the calculated points 3,63), 2nd degree of 3 class of harmful pressure on vocal apparatus (27,52±3,54 hours), 1 degree of 3 class of harmful by equivalent noise level and unfavorable microclimate. The most widespread pathologies of the vocal apparatus are chronic hypertrophic laryngitis (190,20±22,61) and chronic catarrhal laryngitis (131,00±15,07 cases). Almost 70% of occupational laryngitis cases are in the age group of 46-60 years. The critical length of service influenced by voice load is 10-19 years. The length of service more than 20 years in conditions of voice load increases the etiological percent of occupational pathology causes to 81,8%. Therefore, an age of 45,8±0,5 and older is dangerous for the occupational laryngitis progression and requires a special approach of development and implementation of preventive measures aimed at maintaining of occupational health. Suggested complex of measures increase the healthy life by 7,3 years and reduce the loss of healthy life years determined by the impact of voice activity by 7,1 years.

The study of the strength of dentures with different surface reliefs under the action of static loading. Kolomiets L.V., Orobey V.F., Lymarenko O.M., Ovcharov Y.V., Tsilvik O.V. The paper presents modeling of denture specimens with different surface reliefs under the action of static loading using modern numerical methods finite and boundary elements. Based on the analysis of literature, it is shown that the most effective approaches for calculating the stress-strain state (SSS) of dentures is the finite element method (FEM), which allows you to create 3D models with any complexity of geometry and surface, as well as the boundary element method (BEM), which allows in some cases to obtain more accurate calculation results than finite element method. The algorithm and procedure for exact integration of differential equations of hollow shells according to the algorithm of Kantorovich-Vlasov variational method are presented for the formation of the calculated finite element method ratios. The analytical expressions for the parameters of the hollow shells used for calculations of the state of dentures are given. Finite element method is represented in the work by the universal package SolidWorks. Different stages of solid-state modeling of prototypes of dentures with different surface reliefs are shown in detail. Dental stress-strain state calculations were performed by two methods. The results of the calculations are in good agreement with each other, which proves the reliability of both models developed and the results of the stress-strain state received. It is shown that the smallest values of stresses occur in dentures with a rhombic lattice; they are 5.9% less than prosthesis with a smooth surface, and 18.78% less than in prosthesis with a square lattice. Equivalent displacement of a rhombic lath prosthesis is less by 3.864% than that of a smooth surface prosthesis and 8 52% less than a square lattice prosthesis. Реферат.

У роботі представлено моделювання зразків зубних протезів з різними поверхневими рельєфами при дії статичного навантаження за допомогою сучасних чисельних методів – скінченних та граничних елементів. На підставі проведеного аналізу літературних джерел показано, що найбільш ефективними підходами для розрахунку напружено-деформованого стану (НДС) зубних протезів є метод скінченних елементів (МСЕ), який дозволяє створювати 3D моделі з будь-якою складністю геометрії і поверхні, а також метод граничних елементів (МГЕ), який дозволяє в ряді випадків отримувати більш точні результати розрахунків порівняно з МСЕ.

. The association of coronary artery calcium score with glomerular filtration rate and the influence of sex, age, blood pressure, and cholesterol. Bosdriesz J.R., Semenov V.V., Kuryata O.V. Chronic kidney disease puts an individual at a higher risk of all-cause and cardiovascular death. Coronary artery calcium score reflects the accumulation of calcium in the walls of the coronary arteries and a higher coronary artery calcium score is associated with lower survival rates. It is unclear if control of conventional risk factors is enough to reduce cardiovascular risk in patients with chronic kidney disease. The aim of this study was to investigate if the association between estimated glomerular filtration rate and coronary artery calcium score in the Ukrainian population differs by sex, age, blood pressure, and total cholesterol. This cross-sectional study was conducted on a sample of patients who underwent measurement of coronary artery calcium score at Dnipropetrovsk Mechnikov Regional Hospital, Dnipro, Ukraine. Inclusion criteria: age >40 years old, available data about coronary artery calcium score and estimated glomerular filtration rate. Exclusion criteria: the presence of known cardiovascular disease, diagnosis of diabetes mellitus, estimated glomerular filtration rate <30 ml/min and extreme coronary artery calcification (coronary artery calcium score >1500 Agatston units). 137 patients (54 males and 83 females), median age 59.0 [54.0;67.0] years were enrolled in the study. In the patients with lower eGFR there was non-significantly higher coronary artery calcium score (p=0.07). In males with eGFR ≥ 90 ml/min, 60-89 ml/min, and 30-59 ml/min coronary artery calcium score didn’t differ significantly, while in females a lower estimated glomerular filtration rate was associated with a higher coronary artery calcium score. A lower estimated glomerular filtration rate was significantly associated with a higher coronary artery calcium score in the patients with systolic blood pressure ≥ 140 mmHg (p=0.04), but not in patients with diastolic blood pressure ≥ 90 mmHg. In the patients with total cholesterol <5.0 mmol/l and ≥ 5.0 mmol/l coronary artery calcium score tended to be higher in the patients with lower estimated glomerular filtration rate. A lower estimated glomerular filtration rate in our study was associated with a higher coronary artery calcium score in females, patients aged ≥ 55 years old and in patients with systolic blood pressure ≥ 140 mmHg.

. Substantiation of the ethiopathogenic choice of substitution therapy medications for the dry eye syndrome. The purpose of the study is to substantiate the personalized selection of substitution therapy medications with the consideration of the pathogenesis of dry eye syndrome development in each patient. In order to achieve the set goal, we conducted a content-analysis of the information from nomenclature on active ingredient as well as on the mechanisms of action of substitution therapy medications provided in the prescribing information and labeling of the medications. After that, we performed a pathogenetic ranging of substitution therapy medications depending on the way they influence a certain aspect of disorder of the tear film renewal process in dry eye syndrome. The information received in the course of the conducted research makes it possible for an ophthalmologist – basing on information on the disorder in the quantitative and qualitative correlation between the tear film layers received with the help of modern diagnostic tools to prescribe targeted dry eye syndrome treatment taking into account the necessary point of application of the substitution therapy medications, considering their composition and action mechanism of the active ingredients which they contain.

ANRIL (Antisense Non-coding RNA in the INK4 Locus, also known as CDKN2B-AS1) – 3.8-kb long non-coding RNA transcribed from the antisense strand of INK4b-ARF-INK4a gene cluster. It is known that ANRIL overexpression is associated with development of oncological pathologies of different localization. In addition, there are a number of studies devoted to role of ANRIL genetic polymorphism in emergence and progression of tumors, including tumors of genitourinary system. The aim of the study was to check the possible association between ANRIL gene polymorphism rs4977574 and kidney cancer development in representatives of Ukrainian population. Whole venous blood of 101 patients with clear cell renal cell carcinoma (CCRCC) (42 women and 59 men) and 100 patients without oncology history (34 women and 66 men) was used in the study. DNA from blood white cells was extracted using GeneJET Whole Blood Genomic DNA Purification Mini Kit (Thermo Fisher Scientific, USA). Genotyping of rs4977574 ANRIL gene polymorphic locus was performed using real-time polymerase chain reaction (real-time PCR) method in the presence of TaqMan assay C_31720978_30. The mathematical data were processed using the SPSS software package (version 17.0). P values <0.05 were considered as statistically significant. It was found that difference in rs4977574-genotype distribution between patients with CCRCC and control persons was absent in general group (P=0.216). At the same time, the statistical analysis stratified by gender showed that both in female and male subjects rs4977574-genotypes frequency also did not differ significantly between comparison groups (P=0.526 and P=0.160, respectively). However, after adjusting for age, body mass index, and smoking habits statistically significant association between rs4977574 ANRIL gene polymorphism and risk of kidney cancer development was detected in male subjects under superdominant inheritance model (P=0.049). It was revealed that heterozygotes (AG-genotype) have 2.17-fold higher risk of CCRCC development (95% CI=1.005-4.695) compared to patients with AA- and GG-genotypes. In summary, this is the first report about ANRIL gene polymorphisms association with kidney cancer. Obtained results revealed that rs4977574 is related to kidney cancer risk only in Ukrainian men. Male individuals with AG-genotype have higher risk of CCRCC development compared to AA- and GG-genotypes carriers.

Concurrent development of primary brain tumors and multiple sclerosis is quite rare. Only a few dozens of such comorbidity have been reported. Nevertheless, given the fact that such pathologies are characterized by similar clinical picture and neuroimaging findings, issues about diagnosis and differential diagnosis of such conditions often arise, which makes the problem relevant. A literature review was conducted using PubMed, by selecting articles on concurrent multiple sclerosis and brain tumors, particularly glial origin tumors, over the past 20 years (1989 to 2019). The search was performed in English, Russian, and Ukrainian using the following key words and terms: comorbidity, concomitance, multiple sclerosis, brain tumor, glioma, astrocytoma, glioblastoma. The analysis included all articles on etiology, pathogenesis, clinical picture, diagnosis, differential diagnosis, neuroimaging, and pathomorphological assessment. After identifying all the articles that met the inclusion criteria and removing duplicate data, 35 literature sources on concurrent primary brain tumors and multiple sclerosis were selected. The conclusion on whether concurrent primary brain tumors and multiple sclerosis develop randomly or have common pathophysiological mechanisms is still under discussion. Potential causes of pathogenesis of both diseases include viral infection, chronic inflammation, neoplastic transformation, and involvement of neurotropic growth factors. The likelihood that two processes, demyelinating and neoplastic, can develop in parallel will never be underestimated. In such cases, strong clinical suspicion arises due to atypical clinical picture characterized by aggressive and rapidly growing neurological symptoms such as aphasia, spastic hemiparesis, epileptic seizures, or signs of intracranial hypertension. In MRI diagnosis, pathological findings such as single lesion of more than 2 cm; mass effect, edema, signal amplification in the form of ring-shaped shadow are the reasons for a more thorough examination and applying additional diagnostic methods: CT, MR spectroscopy, PET, CSF tests to determine oligoclonal antibodies and other markers content, cerebral biopsy. According to the literature, cases of concurrent primary brain tumors and multiple sclerosis are rare though described. Atypical clinical signs, neuroimaging data, and cerebral biopsy which is currently considered as the only method for making accurate diagnosis are helpful in the diagnostic process.

Disorder of the relationship between biotic and abiotic elements against the background of anthropogenic stress on the human body affects the course of bone remodeling. It is bone tissue in the human body that has the greatest cumulative properties with respect to many xenobiotics, lead in particular. The accumulation of lead in the bone leads to the replacement of calcium ions by ions of the abiotic element and causes further changes in the bone structure: inhibition of growth processes, decreased density, the development of osteopenia and osteoporosis. In the article, a comparative hygienic analysis of bone mineral density levels (according to T-score) in industrial (n=68) and control (n=70) areas was conducted. The T-score, calculated at the LI-LIV level obtained by the method of dual-energy X-ray absorptiometry was used and was evaluated according to the recommendations of the WHO. The formation of a homogeneous sample of persons for the study was conducted according to the place of residence, age, sex, absence of diseases and regular intake of drugs leading to a decrease in bone mass. Summarizing the results, it should be noted that the population of Dniprо city has a more negative and significant decrease in the bone mineral density (according to the T-score) compared to the same values of the control areas – 2.15-4.6 times and Ukraine's – 1.39-4.21 times. According to WHO recommendations, T-score indices for residents of industrial territory indicate to the presence of osteopenia, while among residents of the control area, the norm for this indicator is noted. Consequently, there is an effect of man-made including lead, pollution of the environment on the level of bone mineral density in the industrial city this contributes to the development of osteoporotic changes in the population.

coal miners. The problem of diagnosis in the early and preclinical stages of diseases is important in the prevention of occupational diseases and their complications, because this is the key to the timely initiation of treatment, the implementation of preventive measures. Chronic lumbosacral radiculopathy (CLSR) or low back pain (LBP) is one of the most common diseases in the structure of occupational pathology in Ukraine, which usually develops in those of working professions associated with physical activity, forced work posture, effect of high levels of general vibration, etc. The highest levels of occupational morbidity are recorded in the coal industry, which accounts for about 80% of occupational pathology in Ukraine. Above 1600 cases of CLRS are diagnosed annually in the country. A risk factor for the development of the CLSR is osteoporosis, which arises due to the impairment of quantitative and qualitative characteristics of bone tissue and is characterized by a decrease in its strength, an impairment of microarchitecture with a further increase in risk of fractures. One of the modern methods of assessing condition of bone tissue is determination of the content of macro- and trace elements (MaE and ME) in the biological environments of patients. Ca, Al, Mg, B, P are the most important in the formation and development of bone and connective tissue. To date, studies of bone tissue status in patients with CLSR of professional etiology have not been conducted (small in numbers). Goal – to determine the role of essential elements Ca, Al, Mg, B, P in serum and urine in the formation of occupational CLSR in miners. The research was conducted in 20 miners with CLRS (slaughterer, mining worker of a clearing face (MWCF), drifter) of coal mining industry of Donbass and Lviv-Volyn basins. The results were analyzed in two groups: І group consisted of patients with 10-15 years of work experience (n=10), II group with 16-32 years of work experience (n=10). The control group included 22 patients without pathology of the musculoskeletal system and connective tissue. The inductively coupled plasma atomic emission spectroscopy method (ICPAE) was used to determine the MaE and ME concentrations. The study revealed that the average serum aluminum (Al) concentration in miners with occupational CLSR (115.07 μ mol/l) exceeded control group level (3.3 μ mol/l) by almost 30 times (p<0.05). Serum boron (B) concentration in both age groups (25.90 μ Mol/l and 19.43 μ Mol/l, respectively) were lower than in the control (62.90 μ Mol/l), (p<0.05). The average serum calcium (Ca) concentration in patients with occupational CLSR (2.82 mmol/l) was 1.3 times higher than the same indicator in the control group (2.16 mmol/l), with a significant difference between the two age groups (p<0.05). It was revealed that the average level of phosphorus (P) in the urine of patients with occupational CLSR (19.0 mmol/l) significantly exceeded its content in patients of control group (11.96

Nowadays, there are a number of respiratory illnesses that directly affect children. Exhaled nitric oxide measurement (FeNO) is one of the modern methods of investigation used for diagnosing and controlling allergic eosinophilic airway inflammation. It is a simple, painless and time-saving method for the patient. Because of its non-invasiveness and simplicity, it is a valuable diagnostic method, especially in younger children. Measurement of FeNO is a recognized biomarker and an accurate quantitative indicator in the detection, assessment and monitoring of airway inflammation, including asthma. However, only a few studies assess the relationship between FeNO and level of air pollution. The aim of our study is to determine the relationship between FeNO in third-grade students of primary schools and the level of air pollution in Ruzomberok. 146 children aged 8-10 years were included in the research. This is the first stage of a wider research project involving FeNO measurements in children at different times of the year. The goal of the research is to determine the concentration of FeNO in the studied group of children in the autumn when air pollution is lower than in second stage which is observed in winter. The study showed elevated values of FeNO>20 ppb in 11% of the tested children and correct values <20 ppb in 89% of them. Level of average air pollution in survey days for PM10 ranged from 23 to 40 μg/m3 and for NO2 – from 28 to 44 μg/m3. The study shows that the significant majority of children have normal levels of nitric oxide in the exhaled air when air pollution is low. Analysis of the second phase of FeNO measurements in winter, when air pollution was higher, will allow to compare the results and assess the correlation between the FeNO value and air pollution.
