Comparative Description

The identification of parameters of the cardio-vascular system has not only medical but also social and economic aspects. The work affects the age-related aspects of the state of the cardio-vascular system at different age groups of the female population of Ugra. It was demonstrated the increase in aboriginal and migrant populations of sympathetic activity status autonomous nervous system with age, but a separate component - cardiointervals - operates in different ways in these two groups. The volume of the quasi-attractors for the cardiointervals exponentially decreases in Khanty with age. In the immigrant population an increase in the area of quasi-attractors for parabolic type is observed. The increase with age is a poor prognosis for longevity and the age.

Revealing the regularities of human cardiovascular system’s parameters in the North can significantly affect the ongoing efforts to increase the working age and duration of life of inhabitants of Ugra. The work addresses important aspects of the state of cardiovascular system in different age groups. An increase in activity of the sympathetic autonomic system status with age in aboriginal and alien population, but individual components (cardiointervals) in the two groups behave differently. If quasiattractors demonstrate exponential type of dynamics of their size (area) in Khanty, then the non-indigenous population observed parabolic type of changes of the area of quasiattractors.

The article deals with the problem of early neonatal and infant mortality. It is pointed out that recent advances in emergency and intensive care therapy have provided decline in early neonatal and infant mortality. Hemodynamic disorders are reported to be associated with any severe pathology in patients of all age groups including newborns, significantly influence quality of life of patients having experienced a critical condition. Clinical manifestations of hemodynamic disorders in infants are not considered to be specific; they are critically delayed and are not timely recognized. The article describes peculiarities of the cardio-vascular system of newborns that are responsible for the necessity of thorough hemodynamic profile monitoring in order to provide detection of vital function alterations at the early stages, ensure timely onset of intensive therapy and its qualitative performance. Special attention is paid to current methods of determination of central hemodynamic parameters, which are stated to be divided into invasive and non-invasive. The paper also highlights some peculiarities of evaluation of hemodynamic findings using specific monitoring methods and factors influencing the outcome. The article specifies increased interest towards non-invasive monitoring tools of hemodynamic profile in recent years; their relevance is stated to be doubtless in both pediatric and neonatal practice. The main task of any monitoring procedure is reported to be hemodynamic findings analysis, “trend tracking” in the process of monitoring a patient and intensive therapy performance.

Purpose: to assess the prevalence of corneal diseases using the data on the incidence of visits to outpatient facilities in the city of Baku. Material and methods. The data, presented by outpatient facilities for the year 2017, were statistically analyzed. Results. It was revealed that, for every 100 000 people, there were 266.1±3.4 cases of corneal diseases of which 97.9 ± 2.1 were infectious and 166.9 ± 2.7 were noninfectious diseases. Corneal neoplasms were detected in 1.3 ± 0.2 cases. The ratio of non-infectious and infectious diseases ofthe cornea was ca. 1.7. The lowest prevalence rate of both infectious and non-infectious diseases of the cornea was detected in children aged 0 to 9 years. In older age groups, the change of prevalence of corneal diseases was found to be chaotic. The trends of age-related prevalenceof infectious vs. non-infectious diseases of the cornea were basically similar; the highest rate was detected among patients aged 60–69. Conclusion.According to the appealability data, the prevalence rate of corneal diseases is rather high and age-dependent with a prevailing share of non-infectious corneal pathologies. In male population, this rate is notably lower than in female population.

Pulse wave (PW) is a physiological event, observable and measurable in the arterial system during blood circulation. One of characteristics that can be determined from a PW record is heart rate variability (HRV), an indication of beat-to-beat alterations in the heart rate. HRV is an accurate and reliable reflection of several physiological factors modulating the normal rhythm of the heart. HRV has escalated in use as an important diagnostic tool which indicates the balance between sympathetic and parasympathetic branches of the autonomous nervous system (ANS) and the synchronization between them. HRV patterns are also sensitive to changes in emotional state and can be used to distinguish positive and negative emotions. However, HRV is just one of characteristics that can be extracted from a good quality pulse wave record. Other characteristics of the PW in the time and frequency domains can serve as an indication of the status of a cardio-vascular system. Modern personal health monitoring tools, which use data processing capability of smartphones and personal computers, make daily or even continuous HRV analysis available for users who are affected by sedentary life style, high stress, and fatigue. The practical application of the PW monitoring requires, besides software and electronic, selection of clinically meaningful characteristics of the pulse wave and communicating them to a non-medical user. For this purpose, it is proposed to use, in addition to HRV, to use the characteristics based on duration of the four phases of the pulse wave, and compare them with the baseline level obtained for the same user under non-stressed conditions. Deviations from the baseline are presented to the user. Correlation of these readings with objective parameters of the cardio-vascular system is supported by clinical data.

Transcultural Adaptation

This paper reviews research on young migrants in Germany. Particular attention is given to the question of how Germany’s history of migration, immigration policies, and public attitude toward migrants influence the transcultural adaptation of children and adolescents from different ethnic backgrounds. We combine past research with the results of new empirical studies in order to shed light on migrants’ psychological and sociocultural adaptation. Studies comparing young migrants and their German peers in terms of psychological well-being, life satisfaction, and mental health outcome suggest higher rates of emotional and behavioral problems among migrants of most age groups. With regard to adolescent populations between the ages of 14 and 17 years, however, the existence of differences between migrants and natives appears to be less clear. Research has also yielded inconsistent findings regarding the time trajectory of transcultural adaptation among adolescents. The coincidence of acculturation and age-related change is discussed as a possible source of these inconsistencies. Further, we provide an overview of risk and protective factors such as conflicting role expectations and ethnic discrimination, which may cause heightened vulnerability to adverse adaptation outcomes in some groups. Large-scale studies have repeatedly shown migrants of all age groups to be less successful within the German school system, indicating poor sociocultural adaptation. Possible explanations, such as the idiosyncrasies of the German school system, are presented. Our own studies contribute to the understanding of young migrants’ adaptation process by showing that it is their orientation to German culture, rather than the acculturation strategy of integration, that leads to the most positive psychological and sociocultural outcomes. The paper concludes by discussing implications for future cross-cultural research on young migrants and by suggesting recommendations for multicultural policies.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

Pathological changes in the prostate gland occur commonly with advancing age including inflammation, atrophy, hyperplasia and carcinoma and a change in volume is also evident. Estimation of volume of prostate may be useful in a variety of clinical settings. A cross-sectional descriptive study was designed to see the changes in volume of the prostate with advancing age and done in the Department of Anatomy, Dhaka Medical College, Dhaka from August 2006 to June 2007. The study was performed on 70 post-mortem human prostates collected from the unclaimed dead bodies that were under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age groups; group A (10-20 years), group B (21-40 years) and group C (41-70 years). Volume of the sample was measured by using the ellipsoid formula. The mean ± SD volume of prostate was 7.68 ± 3.64 cm3 in group A, 10.61 ± 3.99 cm3 in group B and 15.40 ± 6.31 cm3 in group C. Mean difference in volume between group A and group C, group B and group C were statistically significant (p<0.001). Statistically significant positive correlation was found between age and volume of prostate (r = + 0.579, p < 0.001). Key Words: Prostate; volume; Bangladeshi. DOI: 10.3329/imcj.v4i2.6501Ibrahim Med.

According to the authors, rationing the age-related EEG parameters in children should be based on personal psychical characteristics. A comparative analysis of personal psychical characteristics and electroencephalographic data was carried out in 300 apparently healthy children aged 3-15 years. According to this principle, two subgroups of conditionally healthy children in each age group were singled out: 1) with an immature attention function and 2) with an increased anxious background that do not reach the pathological level. Registration and analysis of EEG was performed by the Neurokariograf computer complex (MBN, Moscow) using mathematical processing methods.The EEG interpretation was based on the principle of assessing the functional state of a child's brain using a three-component model according to: 1) wakefulness level and its dissociation, 2) severity of signs of the EEG neurotic pattern, 3) directionality of formation of traits of the system-functional brain organization (severity of signs functional hypofrontality).lt was found the presence of EEG signs was indicative of a lower level of wakefulness in children with an immature function of attention in all age groups, compared with the indicators of the average population of group and children with an increased background of anxiety. Children with an increased background of anxiety have a tendency to prevalence and excessive spatial synchronization of the alpha rhythm. ln healthy children, the fact of a decrease in wakefulness and the presence of signs of anxiety in the clinic and in EEG patterns indicates individual personalities and should not be considered as pathology.
