New view on the compatibility of hemoglobin function in the erythrocytes.

OBJECTIVE: Aim: To study the process of hemoglobin oxidation and the enzymatic reactions associated with it. PATIENTS AND METHODS: Materials and Methods: Heparinized human blood (15 IU/ml) was obtained from the clinical department. The concentration of oxy- and methemoglobin, auto-oxidation of hemoglobin was determined spectrophotometrically spectrophotometrically. Autooxidation of hemoglobin was recorded spectrophotometrically, and protein concentration was determined by the Lowry method. Monooxygenase activity of hemoglobin was also measured by the method described by Lowry spectrophotometrically. The concentration of O2 and H2O2 in the reaction media was determined on a biomicroanalyzer OR 210/3 (Redelkis). RESULTS: Results: The obtained experimental data allow us to propose a mechanism of "spontaneous autooxidation" of oxyhemoglobin, which can be described by the following equations: Hb2+O2 → Hb3+ + O2 - (1) Hb2+O2 + 2e - + 2H+ →Hb3+ + H2O2 (2) Hb2+O2 + 2e - + 2H+ →Hb2+ + H2O2 (3) Hb2+ + O2 →Hb2+O2 (4) Spectral characteristics of the process of "spontaneous auto-oxidation" indicate the formation of a metform of hemoglobin, the depletion of oxygen by the system was established, at pH 5.6, an increase in the monooxygenase activity of hemoglobin is observed 3-4 times compared to the physiological level. CONCLUSION: Сonclusions: In addition to the main, previously known functions of hemoglobin (gas transport, peroxidase, monooxygenase), it catalyzes a two-electron oxidase reaction in which O2 is reduced to H2O2. This is confirmed by experimental data on the formation of one of the products of "spontaneous autoxidation" of oxyhemoglobin _ deoxyform at pH 5.6 _ 8.9.

ANALYSIS OF THE BLOOD HYPERCOAGULATION RISK IN PATIENTS WITH ISCHEMIC ATHEROTHROMBOTIC STROKE DEPENDING OF THE VDR GENE POLYMORPHISMS.

OBJECTIVE: Aim: of our study was the analysis of the blood hypercoagulation risk in patients with ischemic atherotrombotic stroke depending of the VDR gene polymorphisms. PATIENTS AND METHODS: Materials and Methods: Blood of 170 patients with ischemic atherothrombotic stroke (IATS) and 124 healthy individuals (control group) was used for genotyping. Four polymorphisms (FokI, BsmI, ApaI, TaqI) of gene VDR were examined with PCR-RFLP methodology. Statistical analysis was performed by using SPSS-17.0 program. RESULTS: Results: Among patients with IATS who are carriers of the f/f genotype, FokI polymorphism of VDR gene by high thrombin time and a decrease in the rate of spontaneous fibrinolysis was registered. In individuals with the B/B genotype homozygous for the polymorphic variant, BsmI had significantly lower mean values of prothrombin and thrombin time and increased the rate of spontaneous fibrinolysis. The homozygotes for the A-allele ApaI polymorphism have 2.7 times higher risk of developing blood hypercoagulation than homozygotes for the a-allele was found. CONCLUSION: Conclusions: Biochemical signs of hypercoagulation syndrome among patients with IATS who are carriers of the f/f genotype of the FokI polymorphic variant and among B/B homozygotes of the BsmI polymorphic variant and homozygotes for the A-allele of the AрaI polymorphism of the VDR gene were registered.

The study used a systematic approach, bibliosemantic, comparative and statistical analysis, and logical generalization. The data were processed and statistically analyzed using Google Forms and Microsoft Excel 2010 for Windows. RESULTS: Results: The study showed that 49 respondents (31.8%) are satisfied with the material and technical support at the workplace and working conditions. Almost all doctors (138 people (89.6%)) said that the actual amount of their salary does not correspond (partially or fully) to the workload at the workplace. Only 4.5% of them said that they receive extra payments for the quality of healthcare services, 21.4% of them said that they receive extra payments periodically, and 74.1% said that they do not receive extra payments at all. Despite the high level of workload and dissatisfaction with salaries, the majority of respondents (109 people (70.2%)) would not agree to change their profession to another one, even if the salary was higher. According to doctors, the most important incentives for improving the quality of healthcare services are: moral satisfaction from work and well-coordinated teamwork (76.6% of answers), financial incentives (74.7% of answers), opportunities for professional and career growth (48.7% of answers), respect from patients and society (46.8% of answers), and management recognition (13.6% of answers). CONCLUSION: Conclusions: The study has shown that today, in the context of health care system reform, there is practically no effective motivational component to improve the quality of health care in health care facilities in Sumy: 40.9% of people gave negative answers, 42.2% of people indicated only its partial existence. Regardless of the length of service, for all respondents, one of the most important motivational incentives is not only material but also moral factors and public recognition.

BEHAVIORAL, SOCIAL, ECONOMIC AND LEGAL DIMENSION OF THE PUBLIC HEALTH SYSTEM OF UKRAINE: DESCRIPTIVE, CANONICAL AND FACTOR ANALYSIS.

OBJECTIVE: The aim is to develop an integrated indicator that characterizes the degree of satisfaction of the population with medical services. PATIENTS AND METHODS: Materials and methods: integrated indicator was formed in terms of three stages for 24 regions of Ukraine and Kyiv. At the first stage, the expediency of using five influential groups of input indicators (behavioral, physical, economic, social and legal orientation) with a total of 59 features using descriptive modeling is substantiated. At the second stage, canonical correlation models were developed for the most correlated complex features, which form an indicator of the population satisfaction degree with the received medical services: physical condition features, social and behavioral orientation qualities. The third stage of factor modeling (using orthogonal transformation methods Varimax, Quartimax and Equimax) allowed identifying the five most influential factors for the formation of an integrated indicator and the development of econometric models for the healthcare state. RESULTS: Results: the necessity to improve the medical service quality and innovation in healthcare reform is confirmed since there were no regions where citizens were fully satisfied with the medical service level. The population of most Ukrainian regions (76% of regions), including Kyiv, is rather dissatisfied with the received medical services. CONCLUSION: Conclusions: the study results provide ample opportunities for healthcare workers, medical professionals, and public authorities to ensure quality and timely adjustment of existing rules and regulations within the Health Care Reform, improving the level of public satisfaction with the received medical services, and the immediate improvement of the nation's health.

Features of the adenoiditis in inflammatory and non-inflammatory diseases of nose and PS were proved. CONCLUSION: Conclusions: 1. PT ultra-microscopy in control group shows great activity of lymphocytes and high energy exchange of cells, with prevailing B-lymphocyte population. 2. The complex of PT ultra structural changes while nose and PS inflammatory diseases shows the activation of immune reaction in competent cells with T-lymphocyte increase in patients older than 25, which witnesses chronic inflammation. 3. In group with nose and PT non-inflammatory diseases, activity of PT B-lymphocytes is unchanged accompanied by the T-lymphocytes growth, which is also characteristic for chronic inflammation.

Antibiotic resistance of the nasopharynx microbiota in patients with inflammatory processes.

OBJECTIVE: The aim: To study the species composition of microorganisms isolated from patients with inflammatory processes of different localization and to monitor the sensitivity of isolated microorganisms to the most commonly used antibiotics. PATIENTS AND METHODS: Materials and methods: During 2017-2019, we examined 517 patients with acute inflammatory processes of the nasopharynx. To establish the etiological structure of pathogens of inflammatory processes, a microbiological study of nasopharyngeal washes was carried out using classical methods of isolation and identification of microorganisms. The sampling of the test material from patients was performed during the first visit to a doctor, before the appointment and implementation of etiopathogenetic therapy. To study the sensitivity of isolated microorganisms to antibacterial drugs, we used the method of paper disks (manufactured by "Pharmaktiv" Ltd. (Kyiv, Ukraine) and Himedia (India). RESULTS: Results and conclusions:The microflora of the mucous membranes of the nose and throat in patients with acute inflammatory processes of the nasopharynx is represented mainly by monoisolates of staphylococci and streptococci. The sensitivity of isolated microorganisms to antibiotics varied between different types of microorganisms and between different antibiotics.Cefazolin showed efficacy against all types of microorganisms. K. pneumonia strains showed the highest antibiotic resistance. Among the gram-positive cocci, 18 strains (4.2%) resistant to all antibiotics were isolated, which can be regarded as the circulation of hospital strains outside the medical institutions.

The impact of an educational institution on development of healthy lifestyle skills for prevention of obesity in adolescents.

OBJECTIVE: The aim: To determine that nature of perception of an educational institution has on degree of risk as to development of bad habits in eating and daily routine. PATIENTS AND METHODS: Materials and methods: We have conducted surveys among 1015 students of educational institutions, residing in a large industrial center through special questionnaire was developed by SI «ICAHC NAMS¼. According to answer to the question about their attitude towards school, schoolchildren have been divided into 6 groups. RESULTS: Results: Studying the health-shaping behavior of children has shown the greatest regularity of engagement in sports activities among students of the 1st group. Schoolchildren of the 4th group were characterized by the risk of development of obesity, due to the highest (among the other groups) level of consumption of chips, crackers, street food, sparkling water, against insufficient acquirement of key sources of protein and vitamins. The same groups also differed in self-esteem of their own health and perception of school environment. CONCLUSION: Conclusions: The most safe group as to development of obesity and other diseases has been the 1st group, students of which attended an educational institution with pleasure and had a high level of physical activity and had certain eating habits. Children of the 4th group with indifferent attitude towards any occupation should be included into the risk group. Outstanding remains the issue in-depth study of prevalence of healthy lifestyle skills and bad habits among various gender groups of adolescents.

Method of forensic assessment of risk factors of treatment failure outcomes as an element of quality management of medical care.

OBJECTIVE: The aim: The aim of this research was to study causes of the development of adverse outcomes in isolated femоral diaphyseal fractures. PATIENTS AND METHODS: Materials and methods: A retrospective analysis of the protocols of clinical and radiological examination of 21 patients was performed. Based on the initial expert assessment, these patients have not been established the severity of injuries due to the development of complications in the postoperative period. CONCLUSION: Conclusions: Patient-dependent, implant-dependent, and surgery-dependent causes that caused a violation of the stability of osteosynthesis (95.2%) were identified. This led to a secondary displacement of bone fragments (71.4%), delayed fracture consolidation (61.9%), the formation of pseudarthrosis (38.1%), the development of post-traumatic osteomyelitis (14,3), migration of screws from the osseous plate (47.6%), and the development of post-traumatic contracture of the knee joint (81.0%).

Morphogenesis of maxillary sinuses in infants, during early and first childhood.

OBJECTIVE: The aim: To study the peculiarities of the structure and to see the development of maxillary sinuses in infants, during the early and first childhood periods of human ontogenesis. PATIENTS AND METHODS: Materials and methods: The study of the peculiarities of the development and formation of the maxillary sinuses' wall was carried out on 50 species of the upper jaws, turtles and sections of the head of the human corpses during different periods of ontogenesis (in infants, during early and first childhood) with the help of histological examination, preparation, CT scan, radiography and morphometry. RESULTS: Results and conclussions: In infants and during the early and first childhood periods of human ontogenesis in the MS there are changes in both quantitative and qualitative nature. In infants (10 days - 1 year), maxillary sinuse is located more lateral to the basis of the lower nasal concha. In this period, it begins to form its lower wall, which in the form of a narrow strip invaginates into the alveolar process. The growth of the sinus is due to the protrusion of the external wall in the direction of the zygomatic bone. The wall of the maxillary sinuse is covered with mucosa (respiratory mucous membrane), which is lined by pseudostratified columnar ciliated epithelium, which is located on the basement membrane. X-ray examination of maxillary sinuse in infants shows that it is a pear-shaped in the anterior projection. Clearly the following walls of the sinuses are visible: the upper, the lower, one, which is arched-shaped, the front and the median, which in lower part are crossed as arch to each other. Investigation of biological specimens of the maxillofacial area of the early childhood period (1-3 years) showed that maxillary sinuses in all specimens are determined more laterally to the basis of the lower nasal concha. Its vertical dimension is 7.5-8.0 mm, transverse - 5.7-6.0 mm, anterior-posterior - 13.9-14.5 mm. X-ray examination of maxillary sinuse in early childhood in the front projection shows that it has an oval shape. There are the following walls of the sinus: upper, lower, front and middle. The study of biological specimens of the facial area in the period of the first childhood (4-7 years) has been established that the configuration of maxillary sinuse is changing. All walls are determined, but the upper wall is rather short, and the front wall is narrow. The median wall has the most prominent development. On X-rays in the anterior projection, a slight extension of the maxillary sinuse is noted laterally. Therefore, one should thoroughly study the peculiarities of the development and structure of the walls of the maxillary sinuses in order to prevent the development of complications and to achieve the treatment of inflammatory diseases of the MS in an optimal term.
