Atopic Bronchial Asthma

Background. In most industrialized countries, allergic diseases affect up to 20% of the population. This pathology belongs to the most common in children: according to the World Health Organization, more than 15% of the world's child population suffers from it. In recent years, there has been a significant increase in the frequency and more severe course of these diseases, in connection with which they are considered in modern society as a major medical and social problem. Thus, the prevalence of bronchial asthma, according to domestic and foreign authors, ranges from 0.2 to 8.1%. Purpose. In order to clarify the role of the autonomic nervous system in the genesis of the mild course of atopic bronchial asthma in childhood, the features of the interaction of the sympathetic and parasympathetic divisions of the autonomic nervous system in the examined children were clarified. Materials and methods. 126 children aged 10 to 14 years were examined. Atopic bronchial asthma was diagnosed in 91 children. At the same time, 61 of them were diagnosed with an intermittent course, 30 a mild persistent course of the disease. The control group consisted of 35 healthy children also aged 10 to 14 years. Complaints, anamnesis data were studied in all children, an objective and generally accepted laboratory and instrumental examination was carried out. All examined children underwent daily monitoring of the electrocardiogram, according to the results of which, based on the analysis of time and frequency indicators of heart rate variability, a variant of the initial autonomic tone was established. Results. In children with atopic bronchial asthma, both with intermittent and mild persistent course, an absolute or relative dominance of sympathetic influences was revealed against the background of varying degrees of decrease in parasympathetic activity, which was interpreted as a compensatory reaction of the body in response to chronic allergic inflammation.

Abstract   Within the framework of the research into pathological conditions and syndromes associated with undifferentiated connective tissue dysplasia (UCTD), an emphasis needs to be placed on the changes in heart rhythm. In puberty, the severity of neurovegetative disorders caused by the presence of UCTD might increase manifold. The features of heart rate variability (HRV) in pubertal children against the background of UCTD have been studied insufficiently and require more detailed analysis. This study aims to assess heart rate variability and tone of the autonomic nervous system (ANS) in puberty-aged children with UCTD. Two groups of children were examined, with methods including electrocardiography and cardiointervalography. The main group consisted of 36 puberty-aged children with UCTD, the control group consisted of 30 healthy children. ANS tone was assessed based on the HRV. In the control group of children aged 11, the value of variation range (VR) was 0.18±0.4, mode amplitude (MA) 35.2±2.4, stress index (IN) 72.8±4.3, which corresponds to the state of vegetative balance. As the puberty progresses, the state of eutonia is replaced by the activation of the sympathetic division of the ANS, which becomes most pronounced at the age of 13 years. In the control group of children aged 13, the value of VR was 0.08±0.02, MA 61.7±2.1, SI 210.6±8.6, which corresponds to moderate sympathicotonia. By the end of puberty, in healthy children, the severity of sympathetic activation begins to decrease, and at the age of 15 years, vegetative balance is again observed. However, this pattern is violated in children with UCTD. Upon entering puberty, moderate activation of the sympathetic division of the ANS is already observed in children with UCTD. At the age of 11 years in this group, the value of VR is 0.06±0.02, MA 72.4±3.1, SI 211.2±8.6. At the age of 13, pronounced sympathicotonia is observed, which is confirmed by the values of VR - 0.04±0.01, MA 80.2±4.3 and SI 34.3±14.7. By the end of puberty in children with UCTD, in contrast to the control group, the analyzed parameters indicate not an equilibrium of the ANS, but the predominance of parasympathetic activation. The research provides an insight into heart rate variability in puberty-aged children with UCTD. It was established that healthy children enter puberty in a state of equilibrium of the autonomic nervous system, which in the middle of puberty is replaced by moderate sympathicotonia, and then returns to its original values. Children with the presence of UCTD enter puberty with moderately pronounced sympathicotonia, which gradually increases to pronounced values and is replaced by moderate vagotonia.

Introduction. In connection with the widespread introduction of osteopathy into practical medicine, new facts confi rming its effectiveness are appearing. These facts need theoretical justifi cation. The biodynamic approach is the least studied and scientifi cally proven approach in osteopathy. There are only a few works describing the benefi cial effects of this type of treatment on the autonomic nervous system based on an assessment of heart rate variability. One of the most sensitive indicators of changes in the state of the body is the electrical activity of the skin (EAS), which is widely used in modern polygraphic devices.Goal of research — to investigate the EAS in the physician and in the patient during the session of craniosacral biodynamics (CSB).Materials and methods. The study involved 32 patients who were randomly divided into 2 groups — control group (10 patients) and main group (22 patients). In the control group there were 8 women and 2 men aged from 20 to 65 years (mean age 42±20 years). In the main group, 16 women and 6 men aged from 18 to 68 years (mean age 40±16 years) were examined. Two professional certifi ed computerized polygraphs «Chris» were used, simultaneously recording the EAS values of the doctor and the patient. In the main group, the background indicators were recorded at the fi rst stage (10 minutes), then the procedure of the CSB, which lasted 20 minutes, was recordered. The control group was used only for registration of EAS. At the same time, patients were in the same conditions as in the main group.Results. During the CSB, the state of both the doctor (p<0,001) and the patient (p<0,001) has changed signifi cantly. At the same time, the tendency of changes in individual indicators of EAS in patients during treatment was logical. The altered state of the physician practically did not depend on its original level (p>0,05). However, there was a high relationship between the states of the doctor during contact and non-contact treatment (correlation coeffi cient 0,80, p<0,001). The patient′s initial condition had a moderate, statistically signifi cant relationship with his condition during the treatment (p<0,001). Since the beginning of the craniosacral biodynamics, the patient′s condition has hardly changed. At the same time, the contactless impact on the patient′s body was comparable with the contact effect (correlation coeffi cient 0,97, p<0,001). There was no signifi cant relationship between the states of the physician and the patient before the beginning of the treatment (correlation coeffi cient 0,18, p>0,05). However, in the process of craniosacral biodynamics, a statistically signifi cant relationship was formed between them with a correlation coeffi cient for non-contact exposure equal to 0,49 (p<0,01) and for contact exposure — 0,34 (p<0,05). Biodynamic treatment statistically signifi cantly improved the state of the autonomic nervous system.Conclusion. The study of the electrical activity of the skin in craniosacral biodynamics is a highly informative method, which allows to verify and quantify the changes occurring in the patient and in the physician during the treatment.

The rapid increase in the number of overweight and obese individuals poses a significant threat to the health of the world's population of all ages. Obesity is able to induce a condition of chronic low-intensity inflammation underlying the number of diseases, and, in particular, the diseases of the cardiovascular system. The aim of the study was to determine the relationship between the response of the cardiovascular system and the state of autonomic nervous system to graduated physical exercises in young adults with normal body weight and overweight. Anthropometric measurements of 84 individuals of both sexes aged 18-25 years were carried out. According to the body mass index (BMI), the following groups were defined: control group of 22 individuals (BMI 18,50-24,99 kg/m2), group with overweight individuals (n=20) of both sexes (BMI 25,00-29,99 kg/m2). The condition of the cardio-vascular system was evaluated by heart rate, systolic and diastolic blood pressure; the status of autonomic nervous system was assessed by the Kerdo index. Indicators were evaluated before and immediately after the graduated exercise test. Data obtained were processed statistically. According to the results of the study, the normotоnic type by its response to the physical exercise was found out in both study groups, but the overweight individuals of both sexes demonstrated the cardiovascular indicators were significantly higher compared to the control group. Having finished the physical exercise tests, overweight men and women showed marked sympathicotonia (≥ + 31). The Kerdo᾿s index in 29,65% of male and in 19,01% of female individuals was higher than in the individuals with normal body mass (p <0.05). It can be concluded that the dominance of sympathetic influences is characteristic for overweight individuals after physical activity. Correlation between anthropometric, cardiovascular and Kerdo᾿s index immediately following the physical exertion in overweight individuals indicate impaired autonomic nervous system balance restoration.

The prevalence of obesity is increasing in the industrialized world, so that the World Health Organization considers obesity as a “pandemia” in rich populations. The autonomic nervous system plays a crucial role in the control of energy balance and body weight. This review summarizes our own data and perspectives, emphasizing the influence exerted by autonomic nervous system on energy expenditure and food intake, which are able to determine the body weight. Activation of the sympathetic discharge causes an increase in energy expenditure and a decrease in food intake, while reduction of food intake and body weight loss determines a reduction of the sympathetic activity. On the other hand, pathophysiological mechanisms of the obesity involve alterations of the sympathetic nervous system in accordance with the “Mona Lisa Hypothesis,” an acronym for “most obesities known are low in sympathetic activity.” Furthermore, the parasympathetic influences on the energy expenditure are analyzed in this review, showing that an increase in parasympathetic activity can induce a paradoxical enhancement of energy consumption.

Background: The search for autonomic correlates of emotional processing has been a matter of interest for the scientific community with the goal of identifying the physiological basis of emotion. Despite an extensive state-of-the-art exploring the correlates of emotion, there is no absolute consensus regarding how the body processes an affective state.Objectives: In this work, we aimed to aggregate the literature of psychophysiological studies in the context of emotional induction. Methods: For this purpose, we conducted a systematic review of the literature and a meta-analytic investigation, comparing different measures from the electrodermal, cardiovascular, respiratory and facial systems across emotional categories/dimensions. Two-hundred and ninety-one studies met the inclusion criteria and were quantitatively pooled in random-effects meta-analytic modelling. Results: Heart rate and skin conductance level were the most reported psychophysiological measures. Overall, there was a negligible differentiation between emotional categories with respect to the pooled estimates. Of note, considerable amount of between-studies’ heterogeneity was found in the meta-analytic aggregation. Self-reported ratings of emotional arousal were found to be associated with specific autonomic-nervous system (ANS) indices, particularly with the variation of the skin conductance level. Conclusions: Despite this clear association, there is still a considerable amount of unexplained variability that raises the need for more fine-grained analysis to be implemented in future research in this field.

AbstractIntroduction It is known that physical exercise is beneficial and precipitates adjustments to the autonomic nervous system. However, the effect of exercise on cardiac autonomic modulation in children, despite its importance, is poorly investigated.Objective To bring together current information about the effects of exercise on heart rate variability in healthy and obese children.Methods The literature update was performed through a search for articles in the following databases; PubMed, PEDro, SciELO and Lilacs, using the descriptors “exercise” and “child” in conjunction with the descriptors “autonomic nervous system”, “sympathetic nervous system”, “parasympathetic nervous system” and also with no descriptor, but the key word of this study, “heart rate variability”, from January 2005 to December 2012.Results After removal of items that did not fit the subject of the study, a total of 9 articles were selected, 5 with healthy and 4 with obese children.Conclusion The findings suggest that exercise can act in the normalization of existing alterations in the autonomic nervous system of obese children, as well as serve as a preventative factor in healthy children, enabling healthy development of the autonomic nervous system until the child reaches adulthood.

Introduction: Available data suggest that there is an association between endometriosis and a group of disorders including autonomic nervous system irregularities. A deeper understanding of relationship between endometriosis and autonomic nervous system is needed as it may lead to novel discoveries on the causes or consequences of endometriosis. In this study, we analyzed the prevalence of migraine in patients with endometriosis. Methods: In this cross-sectional study, medical records of women were reviewed through January 2013 to December 2017. Women with laparoscopically proven endometriosis (n = 185) were compared with those without endometriosis (n = 168). The 3-item screening questions (ID Migraine™) test was used to screen migraine. Data were analyzed using SPSS v25 (IBM Corporation). The χ2 test was used for analyzing the nominal parameters and group comparisons. Pearson χ2 was used to study the association between endometriosis and migraine. Results: The mean age was 31.86 ± 4.49 years of the endometriosis group and 28.95 ± 5.11 years of the controls (p = 0.408). The two pre-screening questions of ID Migraine test were answered positively by 86 patients of the endometriosis group (75.4%) and by 53 patients of the control group (54.6%) (p = 0.001). Of these patients, 51 (44.7% of endometriosis group) and 26 (26.8% of control group) were diagnosed as having migraine using 3-item Migraine questionnaire (p = 0.007). Conclusion: This study showed that the prevalence of migraine was significantly higher in patients with endometriosis. Because there is a strong correlation, patients with endometriosis should be screened for headache and migraine to increase the benefits of care.

The main role in maintaining the functioning of the body, its growth, and development belongs to protein. It is involved in the formation of the muscular skeleton and is s part of enzymes, neurotransmitters, hormones. The effect of the autonomic nervous system on total protein metabolism has not been sufficiently studied. It is known that the autonomic nervous system is a structure that is responsible for the homeostasis and stability of the whole organism. It participates in the regulation of the heart, endocrine and external secretion glands, gastrointestinal tract, excretory organs, and more. In our studies, it was found that in chickens of Cobb 500 strain with different tones of the autonomic nervous system during the growing period from the 35th to the 60th day, different contents of total protein, albumin, and globulins were observed and different body weights were recorded. Vagotonic chickens showed the lowest protein metabolism at the age of 35 and 45 days (P ˂ 0.05–0.001) compared with sympathicotonics and normotonics, which tended to increase between 35 and 60 days of rearing compared with other groups of birds, where the studied protein fractions on the contrary decreased. Correlations between total protein, albumin, and bird body weight had a high linear relationship in all groups of chickens (P ˂ 0.05–0.001) and a negative relationship between the 45th and 60th days of rearing in sympathicotonics and normotonics. In birds with a predominance of parasympathetic tone of the autonomic nervous system, this correlation maintained its direction with high reliability (P ˂ 0.05) between body weight and total protein on the 60th day of rearing.

Neurodegenerative Process

Case example: Mrs. H. feels lightheaded intermittently during the day. This happens exclusively when she is up and about. Sometimes she notes graying of vision with these episodes. The feeling is not spinning (i.e., not vertigo). She has fainted twice when standing in line at the grocery store. If she sits, she feels much better. It is worse in the morning but may recur any time of the day. She feels fine while lying in bed at night. Older adults often worry about high blood pressure (BP), yet the opposite problem, low BP, is common among those with DLB or PDD. This is because the Lewy neurodegenerative process impairs the autonomic nervous system. The specific condition that may afflict those with DLB or PDD is orthostatic hypotension. The term orthostatic implies the upright position (i.e., standing); hypotension translates into low BP. Thus, the low BP occurring in these Lewy disorders develops in the upright position; conversely, it is normal or even high when lying down. When standing or walking, the BP may drop so low that fainting occurs. Among people with orthostatic hypotension, the BP is normal when sitting, although in severe cases, even the sitting BP is low. Whereas most people with DLB or PDD do not experience symptoms of orthostatic hypotension, it is sufficiently frequent to deserve attention. It often goes undiagnosed, even when fainting occurs. Unrecognized orthostatic hypotension may limit activities and impair the person’s quality of life. The first half of this chapter provides further background, with focus on BP measurement and recognition of orthostatic hypotension. The last half addresses treatment. The normal autonomic nervous system senses the position of our body with respect to the pull of gravity. It is able to reflexively counter gravity’s downward pull on the blood volume when standing (gravity tends to draw blood toward our feet when standing). An important mechanism for countering gravity’s pull is the constriction of blood vessel diameter in the lower half of the body. These vessels reflexively constrict during standing, in effect forcing blood up to the brain. The autonomic nervous system mediates these and other reflexive changes to stabilize BP.
