There was executed the comparative study of functional indices of the cardiovascular system in adolescent boys aged of 13-16 years, residing in the city of Magadan (n=424) and Moscow (n=437). The recording of functional indices of hemodynamics in adolescents was made by the same method of the volumetric compression oscillometry method with the use of hardware-software complex “Globus” for the noninvasive study of central hemodynamics (“Globus”, Belgorod). There were revealed regional features of the dynamics of the development of the function of the cardiovascular system in adolescents residing under different climatic geographical and ecological conditions. There were established statistically reliable differences in hemodynamic indices during the age period of 13-15 years: Moscow schoolchildren have higher values of the blood pressure, cardiac output, stroke volume and left ventricular stroke power comparing with Magadan counterparts. In Magadan adolescents there was revealed the tendency towards higher values of heart rate. The analysis of the distribution of hemodynamics indices according to the type of self-regulation of blood-circulation shows 63.7% of schoolchildren of Magadan and Moscow to have cardiotype, 26.9% and 41.2% of adolescents are characterized by cardiovascular type, and vascular type is a common feature in 9.4% and 14.4% of examined adolescents.

Vegetative status and adaptive capabilities peculiarities of aged 19 to 21 girls depending on their blood circulation self-regulation type were studied in this work. The study was conducted at the Biology Faculty of Zaporizhzhia National University, Zaporizhzhia. Such primary indices as heart rate and blood pressure were studied in all test individuals. Based on the obtained data, the blood circulation self-regulation type in each subject was determined separately, which allowed to form three groups (individuals with cardiovascular, vascular and mixed blood circulation self-regulation types). The assessment scheme included cardiovascular system indices calculation such as average dynamic arterial pressure, specific peripheral resistance, cardiac output, cardiac index, stroke volume, external myocardial function, myocardial stress index, myocardial efficiency criterion, autonomic regulation index (vegetative Kerdo’s index) and adaptive potential. The results were processed by variation statistics methods, and the obtained data were subjected to correlation analysis. Deviations from the reference values were revealed in systemic hemodynamics ave­rage group parameters analysis in female students with different blood circulation regulation types. It was recorded that the average dynamic pressure exceeded the normal upper limit by 2.5 % and 6.2 %, respectively, in persons with mixed and vascular regulation type. Specific peripheral resistance indices obtained from data analysis in girls with different blood circulation self-regulation types revealed that this index did not exceed the normal in the groups with mixed and vascular type, in contrast to the group with the cardiac type. The specific peripheral resistance was lower by 5.2 % than the lower limit of the reference value for this index in the latter group. Statistically significant differences were identified in cardiac output, cardiac index and stroke volume parameters in girls with different self-regulation circulatory types. Specific trends were identified in the average group and individual myocardial function indices in girls depending on the self-regulation type. Statistical significance was found between myocardial stress indices in girls with different self-regulation types. Both the average group and individual vegetative Kerdo’s index indices fluctuated within eytony in the mixed type persons group. The mean group autonomic index values in girls with vascular type indicated pronounced vagotonia. We found that the largest percentage of all respondents had satisfactory adaptation. The largest number of girls with satisfactory adaptation had a vascular self-regulation type (83.33 %) and a mixed type (81.82 %), a smaller percentage of girls from these groups (16.68 % and 18.18 %, respectively) had adaptation mechanisms functional stress. In the group with the cardiac type, almost half (46.15 %) had adaptation mechanisms functional stress, and the rest (53.85 %) had satisfactory adaptation. Thus, the differences in cardiovascular system indices, the autonomic nervous system sympathetic and parasympathetic parts influences ratio on the cardiovascular system were determined, as well as the adaptive potential in 19-21 years old girls can be attributed to blood circulation compensatory-adaptive reactions.

Relevance. Characteristics of eruption of secondary teeth is of diagnostic and prognostic interest, is the basis for implementation of targeted therapeutic and preventive measures among children. No research has ever been carried out in Uzbekistan to study an age and gender regional features of secondary teeth eruption. The aim is to determine the timing and symmetry of secondary teeth eruption in children of the city of Tashkent of the Republic of Uzbekistan and comparative assessment with the children of different cities of Russia.Materials and methods. 3,834 children between 3 and 17 years were conducted dental examination. A comparative analysis was made of the initial, intermediate and final periods of eruption of secondary teeth for children of Uzbekistan (Tashkent city) and Russia (Saratov, Izhevsk and Sergach).Results. In Tashkent children of both gender, in most cases, lower teeth were erupted before than their antagonists. In girls, teeth were erupted earlier than their male counterparts. At the initial stage of eruption, asymmetry was more pronounced in boys than in girls, while in the middle and final stages it was more pronounced in the opposite direction. Observed asymmetry of antimere’s teeth were indicated left-handed permanent dentition in boys and right-handed in girls. Children of Tashkent city were observed permanent dentition in one group of teeth 1-16 months earlier, and in others – 1-24 months later than their peers in Russian cities. Revealed differences were more pronounced among boys than among girls. Children in Tashkent differed more from their peers in Sergach and less from those in Izhevsk. Conclusions. Regional peculiarities of permanent dentition in children of Tashkent city and revealed expressed differences with indicators of Russian children are the basis for development of separate age and  gender normative assessment permanent dentition tables for children of Uzbekistan.

Dilated cardiomyopathy is the most common type of the heart failure which can be characterized by impaired ventricular contractility. Mechanical circulatory support devices were introduced into practice for the heart failure patients to bridge the time between the decision to transplant and the actual transplantation which is not sufficient due to the state of donor organ supply. In this study, the hemodynamic response of a cardiovascular system that includes a dilated cardiomyopathic heart under support of a newly developed continuous flow left ventricular assist device—Heart Turcica Axial—was evaluated employing computer simulations. For the evaluation, a numerical model which describes the pressure-flow rate relations of Heart Turcica Axial, a cardiovascular system model describing the healthy and pathological hemodynamics, and a baroreflex model regulating the heart rate were used. Heart Turcica Axial was operated between 8000 rpm and 11000 rpm speeds with 1000 rpm increments for assessing the pump performance and response of the cardiovascular system. The results also give an insight about the range of the possible operating speeds of Heart Turcica Axial in a clinical application. Based on the findings, operating speed of Heart Turcica Axial should be between 10000 rpm and 11000 rpm.

This study analyzes the salt / sodium in food, in public policies and health. In this way, it proposes to provide subsidies around the concepts of the importance of the city in the construction of healthy food. The purpose of this review is to discuss the constraints, reflecting on them through theoretical assumptions about the promotion of citizenship and the pasteurization of taste / flavors. Food in society raises the integration of actions, actors and various social spaces, such as: State, schools, associations, businessmen in order to excel, consistent and efficient, by an educating city. In the context of the state of Espírito Santo, for two years, the law 10.369/2015 banned salt shakers at bars and restaurants in Espírito Santo for two years. In this way, research shows that excessive sodium intake (which raises blood pressure and affects the cardiovascular system) brings several complications that can last for many years or even a lifetime.Redução e Consumo de Sódio: Trama entre Cidade, Alimentação e CidadaniaEste estudo analisar o sal/sódio na alimentação, nas políticas públicas e saúde. Desse modo, propõe fornecer subsídios em torno dos conceitos da importância da cidade na construção da alimentação saudável. O objetivo desta revisão é discutir os condicionantes, refletindo sobre eles por meio de pressuposições teóricas sobre a promoção de cidadania e da pasteurização de gosto/sabores. A alimentação na sociedade suscita integração das ações, dos atores e dos diversos espaços sociais, como: Estado, escolas, associações, empresários de modo a primar, consistente e eficiente, por uma cidade educadora. No contexto capixaba, vigou por dois anos a lei 10.369/2015 que proibia saleiros em mesas de bares e restaurantes do Espírito Santo sendo essa uma marco. Desta forma, a pesquisa demonstra que a ingestão excessiva de sódio (que eleva a pressão arterial e afeta o sistema cardiovascular) traz diversas complicações que podem perdurar por muitos anos ou até mesmo a vida toda.

The preparations of polyhydric alcohols, namely sorbitol-based ones, and their combination with adjuvant therapy, namely L-arginine are sufficiently promising for treatment of purulent-septic complications. The systemic nature of their action makes it appropriate to carry out studies of specific effect on the circulatory system, since their wide homeostatic and pharmacodynamic spectrum is beyond doubt for other systems and organs within the “efficiency-safety” algorithm.The objective of the research was to study the effect of combined use of sorbilact and L-arginine on the cardiovascular system of patients with endogenous intoxication syndrome during the period of developing early secondary autoaggression.Materials and methods. The study included 117 patients who were divided into the following groups: Group I consisted of 31 patients with systemic inflammatory response syndrome; Group II included 27 patients with endogenous intoxication syndrome treated according to 2016 Surviving Sepsis Campaign; Group ІІI comprised 29 patients with endogenous intoxication syndrome who received sorbilact in addition to standard therapy; Group IV included 30 patients with systemic inflammatory response syndrome who received standard therapy as well as sorbilact and L-arginine.Results. Co-administration of sorbilact and L-arginine was accompanied by an increase in stroke volume and cardiac output, activation of left ventricular minute work alongside with a moderate decrease in mean arterial pressure and systemic vascular resistance.Conclusions. The application of sorbilact and L-arginine in patients with endogenous intoxication syndrome provides hemodynamic stability.

The cardiovascular system was analyzed in patients with symptomatic (n = 31) and mild primary hyperparathyroidism (n = 34) whose mean age was 54.6 years; 95% females). In the patients with symptomatic primary hyperparathyroidism, the PQ interval was longer and the QT interval was significantly shorter than those in patients with mild hyperparathyroidism. Left ventricular hypertrophy was noted in 45.2% of patients with symptomatic and in 15.2% of those with mild hyperparathyroidism (p = 0.013). Left ventricular diastolic dysfunction was also more common in the group of symptomatic hyperparathyroidism. There was a statistically significant correlation between the levels of parathyroid hormone, total and ionized calcium and the duration of QT interval and the determinants of diastolic function and left ventricular hypertrophy. The revealed cardiovascular disorders in patients with primary hyperparathyroidism are presumed to depend on the increase rate of parathyroid hormone and total and ionized calcium.

Aim. To study cardiac micropotentials registered by the hardware and software complex with nanosensors in patients with myocardial infarction for the early detection of life-threatening conditions.Materials and Methods. The pilot study included 29 patients with acute myocardial infarction who had life-threatening complications such as heart rhythm disorders, the development of acute left ventricular failure, or clinical death prehospitally or at admission to the coronary care unit. The diagnosis of myocardial infarction was established and treatment was carried out according to the national guidelines for the management of patients with myocardial infarction, including the methods of myocardial revascularization.Results. During hospitalization, eight patients developed cardiogenic shock and died. 21 patients survived and were included in the comparison group. At admission, all patients underwent high-resolution electrocardiography using the originally developed hardware and software complex with nanosensors. The micropotentials on the ST segment of the electrocardiogram were recorded for 30 s in three leads on-line. The numbers of micropotentials in the studied groups were analyzed. The analysis of the number of micropotentials within certain ranges of amplitude and duration registered on high-resolution electrocardiogram showed a decrease of the micropotential number in group of patients who died from cardiogenic shock compared with the group of survived patients.Conclusions. The results of this pilot study of cardiac micropotentials are preliminary and require further accumulation of data as well as a search for new criteria for diagnostics, prognosis, and evaluation of the treatment efficacy in patients with myocardial infarction.
