Comparative characteristics of heart rate variability parameters of Yugra pupils

This article presents a comparative analysis of the parameters of HRV students who are indigenous and non-indigenous residents of Yugra. Analysis was carried out carried out by multiple comparisons of three age subgroups and by multivariate analysis with the calculation of inter-cluster distances. The differences in the dynamics of age-related changes of Yugra schoolchildren reveals distinctive trend parameters of heart rate variability between indigenous and non-indigenous representatives of North. In particular, it revealed a higher adaptive capacity in Aboriginal representatives in comparison with the migrant population. The maximum divergence of parameters of the body boys observed in the older age group.

ObjectiveThe aim of this study was to assess age-related changes in cardiac autonomic modulation and heart rate variability (HRV) and their association with spontaneous and pharmacologically induced vulnerability to cardiac arrhythmias, to verify the translational relevance of mouse models for further in-depth evaluation of the link between autonomic changes and increased arrhythmic risk with advancing age.MethodsHeart rate (HR) and time- and frequency-domain indexes of HRV were calculated from Electrocardiogram (ECG) recordings in two groups of conscious mice of different ages (4 and 19 months old) (i) during daily undisturbed conditions, (ii) following peripheral β-adrenergic (atenolol), muscarinic (methylscopolamine), and β-adrenergic + muscarinic blockades, and (iii) following β-adrenergic (isoprenaline) stimulation. Vulnerability to arrhythmias was evaluated during daily undisturbed conditions and following β-adrenergic stimulation.ResultsHRV analysis and HR responses to autonomic blockades revealed that 19-month-old mice had a lower vagal modulation of cardiac function compared with 4-month-old mice. This age-related autonomic effect was not reflected in changes in HR, since intrinsic HR was lower in 19-month-old compared with 4-month-old mice. Both time- and frequency-domain HRV indexes were reduced following muscarinic, but not β-adrenergic blockade in younger mice, and to a lesser extent in older mice, suggesting that HRV is largely modulated by vagal tone in mice. Finally, 19-month-old mice showed a larger vulnerability to both spontaneous and isoprenaline-induced arrhythmias.ConclusionThe present study combines HRV analysis and selective pharmacological autonomic blockades to document an age-related impairment in cardiac vagal modulation in mice which is consistent with the human condition. Given their short life span, mice could be further exploited as an aged model for studying the trajectory of vagal decline with advancing age using HRV measures, and the mechanisms underlying its association with proarrhythmic remodeling of the senescent heart.

The prevalence of osteoarthritis (OA) increases in proportion to age, so in the population of people over 65 years of age. The pathogenesis of OA is based on inflammation of the cartilage tissue of the joint, which leads to damage to the cartilage, activation of signaling pathways and increased levels of cytokines. Aim.To study the literature data on bone and cartilage remodeling with the development of resorptive processes and discuss possible algorithms and recommendations for the management of patients with OA on the background of chondroprotective therapy. Materials and methods.A comprehensive analysis of data presented in open sources, published and available on such resources as PubMed, EMBASE, Cochrane, and Library. Results.According to the available recommendations and the opinion of experts, among the methods of OA therapy, drugs containing pharmaceutical chondroitin sulfate are currently being discussed, which in a number of studies has demonstrated high antiresorptive effectiveness. Conclusion.The use of drugs based on pharmaceutical chondroitin sulfate (Chondroguard) contributes not only to the reduction of pain in OA, but also has a positive effect on the processes of inflammation, including those associated with age-related changes in the body.
