Aim. To study the condition of the autonomic nervous system in groups of adolescents in the period of retention after active orthodontic treatment with non-removable equipment. Methods. Examined were 100 adolescents aged 13-17 years in the period of retention after active orthodontic treatment. The baseline autonomic tone was assessed according to the combined table of sympathetic and parasympathetic reactions (Wayne A., 1981) in the modification of N.A. Belokon’ et al. (1986) for children and adolescents, taken into account were the heart rate, respiratory rate, systolic and diastolic blood pressure. In order to evaluate the adaptation of the organism used was a mathematical analysis of the heart rhythm (cardiointervalography), determined was the mode (Mo), the amplitude of the mode (AMo), and the variational span (ΔX). Results. Revealed were two groups of patients with different variants of the course of retention: favorable course without recurrence (53%) and unfavorable course with recurrences (47%). In the group of patients with recurrences cardiointervalography most frequently showed a asympaticotonic (41.7%) or hypersympaticotonic (58.3%) type of autonomic reactivity. In all patients of the group with recurrences noted was a disturbance of the adaptation processes. The state of adaptation is regarded as unsatisfactory in 72.6% of cases, as the complete adaptation failure - in 27.4%. Conclusion. A recurrence during the period of retention after active orthodontic treatment occurs significantly more frequently in the group of patients with high constraint and overload of the autonomic reactivity, with a mismatch of cardiac rhythm management processes, with a reduction of the adaptive capacity of the organism to the level of complete failure of adaptation; patients who have expressed sympathicotonia, are at risk for destructive periodontal disease and require special attention during the retention period.

Abstract Background A defecation reflex involves sensory information from the colon sent to the central nervous system which results in propulsive motor patterns in the colon through programmed neural activity from the autonomic nervous system. Neurological causes of constipation are recognized but specific neurological pathways that contribute to pathophysiology of the disease is underexplored. Diagnosis and treatment usually do not involve the autonomic nervous system. Aims Our objective was to assess autonomic dysfunction and abnormal defecation reflexes as a possible cause of chronic constipation. Methods Defecation reflexes were assessed by high-resolution colonic manometry through balloon distention, meal intake, and rectal bisacodyl. Specific heart rate variability (HRV) parameters were used to assess general orthostatic autonomic reactivity, and autonomic functioning during high resolution colonic manometry, in 14 patients with chronic refractory constipation considered for surgery. Results All patients had a unique combination of motility, reflex ability and HRV profiles. Patients overall did not generate HAPWs or had lower HAPW amplitude and lower propulsive activity compared to healthy individuals. Half of the 14 patients were tested to have high sympathetic tone based on Baevsky’s stress index prior to HRCM, and 11 of the patients had sympathetic hyper-reactivity and/or low parasympathetic reactivity to at least one type of colonic stimulation during HRCM. Abnormal autonomic tone or autonomic reactivity to colonic stimulation was present in all four patients with absence of the vagosacral defecation reflex. Five of the seven patients with absence of the sacral defecation reflex showed high sympathetic tone or high sympathetic reactivity to stimulation. Only two patients had abnormality in coloanal coordination and this was associated with low parasympathetic reactivity to stimulation in both patients. Conclusions The assumption that colonic resection was needed to remove an inert colon was wrong in most patients, but most patients had some form of reflex abnormality. Sympathetic dominance far outweighed parasympathetic dysfunction. Incorporation of assessments of defecation reflexes and autonomic nervous system activity into diagnosis of chronic refractory constipation provides a comprehensive pathophysiological understanding of specific defective neurological pathways contributing to dysmotility. This forms the basis for our individualized treatment efforts through sacral neuromodulation. Funding Agencies CIHR

In recent decades, the shift in priority in the treatment of patients with pulmonary granulomatosis in the direction of etiotropic therapy and reduced attention to the state of the macroorganism led to a decrease in the effectiveness of treatment. In modern conditions, when carrying out complex therapy for patients with tuberculosis and sarcoidosis, insufficient attention is paid to the state and dynamics of adaptation, resistance, homeostasis and reactivity of the organism. At the same time, the dynamics of these processes in patients is insignificant, the homeostatic balance of the organism is not restored, and the reactivity of the organism remains at the pathological level, with the predominance of paradoxical, hyporeactive and areactive types. This is due to the continuing influence on the regulatory centers of the vegetative system of not diagnosed, latent, ongoing tuberculosis intoxication. Undetected specific intoxication causes in patients activation of the sympathetic department, suppression of parasympathetic and development of dysfunction of the autonomic nervous system. Its dysfunction leads to a decrease in vascular supply of the organism, a high tension of anabolic processes, and a further change in the functional activity of both parts of this system when pathology develops. In addition, the emergence of vegetative dysfunction leads to a high consumption of plastic materials, energy resources, a decrease in the functional reserves of the body, a decrease and depletion of the body’s defense systems, its anti-inflammatory potential and the reactivity of the organism as a whole. These changes lead to an extension of the main course of treatment and the formation of expressed residual tubercular and sarcoidosis in the respiratory organs. To restore these disorders, it is necessary to carry out complex therapy with the inclusion of a personified appointment of activators of protective systems under the control of monitoring their effectiveness.

Introduction. To assess the characteristics of the body’s adaptation of skilled athletes to strenuous exercise, it is most important to define how the manifestation of physical performance of athletes depend on the autonomic regulation of physiological functions of the body. Aim is to study the dependence of the autonomic regulation of heart rate on the manifestation of physical performance of qualified athletes and the reaction of the cardiorespiratory system under conditions of physical activity of different nature. Materials and methods. Determination of physical performance of qualified athletes and the reaction of the cardiorespiratory system (CRS) to test physical activity (ergospirometric complex "Oxycon Pro", treadmill LE-200 C), mathematical analysis of heart rhythm variability, mathematical and statistical methods. Results. The predominance in the regulation of heart rate activity of the parasympathetic division of the autonomic nervous system helps athletes achieve a higher level of physical performance both in terms of physical activity with a predominance of aerobic processes in energy supply and in terms of maximum realization of aerobic capacity. Increased activity of the parasympathetic division of the autonomic nervous system is combined with a reduced level of VE, which indicates the efficiency of the reaction of cattle under physical conditions, mainly aerobic (low and medium power). With increasing intensity of physical activity (starting from the threshold of aerobic metabolism), the increased level of activity of the parasympathetic division of the autonomic nervous system will increase the level of pulmonary ventilation, which characterizes the most effective response of CRS Conclusions. The higher level of activity of the parasympathetic division of the autonomic emergency in the regulation of heart rate contributed to the formation of a more economical pattern of respiratory response due to higher VT and lower fT, which under intense physical work allowed to achieve higher levels of VE and aerobic potential of the athlete. With increasing activity of the sympathetic channel of heart rate regulation, there was a decrease in the efficiency of the respiratory response. Thus, the required operating level VE was formed due to the smaller value of VT at a high level

Annotation. The aim – to find out the features of autonomic support and exercise tolerance of the cardiovascular system in children with chronic non-infectious diseases, in the future will be able to improve the results of diagnosis and rehabilitation of patients, as well as differentially regulate the mode of the exercise regime for patients. The study included 58 children aged 10-17 years, with cardiac and endocrine pathology: group 1 – 23 children with endocrine pathology (type 1 diabetes mellitus), group 2 – 23 children with cardiac pathology (AH stages I-II). The study included clinical examinations, anthropometry, a questionnaire of physical activity by MAOFA, ECG, ultrasound examination of the heart and Rufier's test were performed. Assessment of the state of the autonomic nervous system was carried out using the Kerdo index and COT. Statistical analysis was performed using s/n program SPSS 17 4a 180844250981. It was found that there is a tendency to outstrip the normative values and increased body weight indicators in the examined children with chronic pathology of the endocrine and cardiovascular systems. According to the Rufier test, it was found that in the group of children with diabetes mellitus, 69.5±9.6% of the examined had low results. Among children with hypertension, 30.7±10.4% of the test indicators were regarded as weak, and in 26.9±5.8% – unsatisfactory. The results of Rufier's test were significantly lower in children with endocrine pathology, both in comparison with the group of children with cardiac pathology (p<0.05) and with the control group (p≤0.001). In 70.0±15.3% of cases, weak and unsatisfactory indicators of the Ruffier test were observed against the background of hyperdiastolic autonomic support. In physically nonactive adolescents, asympathicotonic and hyperdiastolic types of COT were observed. Thus, almost 70% of children with diabetes mellitus and 57% of children with arterial hypertension have reduced exercise tolerance. This is associated with hyperdiastolic autonomic support. Physical activity has a positive effect on the state of the autonomic nervous system in children with arterial hypertension and diabetes mellitus.

Background. Heart disease is the leading cause of death in developed countries. Approximately half of these fatalities are due to sudden cardiac death. Electrocardiogram recording from the body surface allows stratification of patients according to the risk of cardiac arrest without the use of invasive methods. Arrhythmias, particularly ventricular extrasystole, can affect the sinus rhythm pattern. The change in sinus rhythm that occurs after an extrasystole is defined as heart rate turbulence. This phenomenon is not pathological, but some variants are associated with a risk of fatal arrhythmias. Aim. To analyze the indices and clinical significance of cardiac rhythm turbulence according to Holter monitoring in patients with various cardiological abnormalities at the hospital profile department. Material and methods. The study included 54 patients who were routinely treated in a cardiac hospital. Cardiac rhythm turbulence indices were obtained by Holter monitoring. Patients in severe and moderately severe clinical condition were not included in the study. Concomitant and past somatic diseases affecting the state of heart and cardiovascular system were considered. Results and discussion. Deviations in heart rhythm turbulence indices can be detected both in life- threatening arrhythmias and in benign extrasystoles. They are associated with the influence of the autonomic nervous system, but probably have different mechanisms. Deviations of heart rhythm turbulence indices were associated with left ventricular myocardial hypertrophy of concentric remodeling type and with an increased number of low-risk ventricular extrasystoles. To identify patients with arrhythmias of different risk, various threshold values of cardiac rhythm turbulence indices can be used. Conclusion. Factors likely to affect the indices of cardiac rhythm turbulence such as left ventricular myocardial remodeling and hypertrophy were revealed, as well as changes in autonomic nervous system regulatory function, including those associated with the constitutional features of the patient.

Heart rate variability (HRV) is highly influenced by the Autonomic Nervous System (ANS). Several illnesses have been associated with changes in the ANS, thus altering the pattern of HRV. However, the variability of the heart rhythm is originated within the Sinus Atrial Node (SAN) which has its own variability. Still, although both oscillators produce HRV, the influence of the SAN on HRV has not yet been exhaustively studied. On the other hand, the complications of diabetes mellitus (DM), for instance, nephropathy, retinopathy, and neuropathy, increase cardiovascular morbidity and mortality. Traditionally, these complications are diagnosed only when the patient is already suffering from the negative symptoms these complications implicate. Consequently, it is of paramount importance to develop new techniques for early diagnosis prior to any deterioration on healthy patients. HRV has been proved to be a valuable, noninvasive clinical evidence for evaluating diseases and even for describing aging and behavior. In this study, several ECGs were recorded and their RR and PP intervals were analyzed to detect the interpotential interval (ii) of the SAN. Additionally, HRV reduction was quantified to identify alterations in the nervous system within the nodal tissue via measuring the SD1/SD2 ratio in a Poincaré plot. With 15 years of DM development, the data showed an age-dependent increase in HRV due to the axon retraction of ANS neurons from its effectors. In addition, these alterations modify the heart rhythm-producing fatal arrhythmias. Therefore, it is possible to avoid the consequences of DM identifying alterations in SAN previous to its symptomatic appearance. This could be used as an early diagnosis indicator.
