The association between supportive social ties and autonomic nervous system function—differences between family ties and friendship ties in a cohort of older adults

AbstractSupportive family and friendship ties can serve different functions and thus might show different associations with an individual’s health. Particularly, older adults might show varying health benefits of different types of supportive ties depending on their marital and retirement status. Our aim is to analyze relationships between different types of supportive social ties and autonomic nervous system (ANS) function, a physiological indicator of health that can help to establish the biological plausibility of the association—measured by heart rate variability (HRV). We present cross-sectional linear regression analyses of a German cohort of community-dwelling older adults (2008–2010; n = 1,548; mean age = 68.7 years). Our findings indicate that supportive friendship ties show significant positive associations (i.e., higher HRV) in individuals that are either not married or above retirement age. Supportive family ties show significant positive associations in individuals below retirement age. Significant results vanish or are reduced after accounting for behavioral/physical and psychological/cognitive indicators. We conclude that programs supporting the development or maintenance of friendship ties might be especially beneficial in unmarried older adults and adults above retirement age.

The objective: was to evaluate the effectiveness of various anesthesia options for laparoscopic hysterectomy, including low-opioid (LOA) and opioid-free anesthesia (OFA) by studying the dynamics of heart rate variability (HRV) indicators.Materials and methods. 102 patients were randomly assigned to 3 groups: 37 patients who received standard opioid anesthesia (control group), 33 women who received the LOA group, and 32 patients who received OFA.Results. Laparoscopic hysterectomy is accompanied by tension of the autonomic nervous system, especially its sympathetic link, which is manifested by an increase in the index of vago-sympathetic interaction at the traumatic stage of the operation. These changes were most significant in patients who received standard and opioid-free anesthesia, which indirectly indicates insufficient stress protection of these types of intraoperative anesthesia.Conclusions. The use of low-opioid anesthesia is accompanied by a greater stabilization of HRV indices, which indicates its sufficient autonomic protection during laparoscopic hysterectomy than standard and opioid-free anesthesia.

Abstract Background: Arterial hypertension has a direct association with endothelial dysfunction and major cardiovascular events. There is evidence showing the benefits of aerobic exercise on flow-mediated dilation (FMD) in hypertensive individuals but little is known about the effect of autonomic nervous system (ANS) activation on FMD of the brachial artery in response to different types of exercise in this specific population. This study aims to examine the effects of ANS activation on FMD of the brachial artery in response to exercise in hypertensive individuals following a session of different types of exercise including aerobic exercise (AE), resistance exercise (RE) or combined exercise (CE). Methods: Thirty-nine hypertensive volunteers aged 35 to 55 years will be randomly assigned to two exercise sessions: AE (40 minutes on a cycle ergometer at 60% of HR reserve); RE (4 lower limb sets with 12 repetitions at 60% 1-RM for 40 minutes) or CE (RE for 20 minutes + AE for 20 minutes). Each exercise group will be randomized to receive either an α1-adrenergic blocker (doxazosin 0.05 mg/kg-1) or placebo. Ultrasound measurement of FMD is performed 10 minutes before and 10, 40 and 70 minutes after exercise. ANS activation is monitored using a Finometer and measurements are taken during 10 minutes before each FMD assessment. Arterial stiffness is assessed by pulse wave velocity (PWV) analysis using a Complior device. Discussion: We expect to demonstrate the effect of ANS activation on FMD of the brachial artery in hypertensive individuals in response to different types of exercise. This study may give some insight on how to improve exercise prescription for hypertension management. Trial registration: www.clinicaltrials.gov (ID: NCT04371757).

The Status

The article presents the characteristics of the status of autonomic nervous system and adaptation in babies with the different types of intrauterine growth restriction (IUGR). In infants the presence of symmetrical IUGR in comparison to asymmetrical IUGR is related to higher frequency of first- and second-degree cerebral ishaemia at birth and autonomic dysfunction starting from the second six months of life. Thus, babies with symmetrical IUGR display: lower sympathetic nervous system activity and depletion of adaptation reserves at the age of two-three days; higher sympathetic activity and strain on adaptation, high frequency of asympathicotonic responsiveness of the autonomic nervous system at the age of one month; higher sympathetic activity and higher frequency of adaptation strain with the prevalence of adaptation failure at the age of three months; lower sympathetic activity and higher frequency of asympathicotonic autonomic responsiveness at the age of six months; higher sympathetic activity and strain on compensatory reserves, higher frequency of asympathicotonic autonomic responsiveness and adaptation dysfunction with the prevalence of unsatisfactory adaptation at the age of 12 months. The proven facts should lead neonatologists and pediatricians to specifically monitor infants having had intrauterine growth restriction in their past medical history, especially those who have suffered from symmetrical intrauterine growth restriction, and to take preventive measures against autonomic dysfunction in the first six months of life of such infants and curative measures starting with non-pharmacologic ones or with a sparing use of drugs in the second six months of life. At the same time, infants having had asymmetrical intrauterine growth restriction demand special attention during the neonatal period and at the age of twelve months.

Background The origin of syncope, a transient loss of consciousness due to cerebral hypoperfusion, remains unclear. Recent studies suggest that a hypersensitive autonomic nervous system might be involved in the pathophysiology of vasovagal syncope (VVS). Purpose Here we test the hypothesis that patients with VVS have a hyper-reactive autonomic nervous system by investigating the peripheral haemodynamic responses during a standing (AS) test in a group of young VVS patients vs a control group. Methods A prospective sample of consecutive patients from a National Falls and Syncope Unit was recruited, and a convenience sample of young healthy community dwelling adults was recruited from a local university (16-30 years). Participants performed a 3 minute AS with continuous measurement of beat-to-beat blood pressure (BP), heart rate (HR), and cerebral oxygenation measured with near infrared spectroscopy. Baseline, steady-state and other time domain features were obtained for systolic BP (SBP) (i.e. nadir, overshoot, overshoot-to-nadir, overshoot-to-nadir recovery rate) and for HR (i.e. peak, trough, peak-to-trough, peak-to-trough recovery rate). Multiple linear regression was used to compare these features between patients and controls while correcting for covariates (p < 0.05 significant). Results Forty patients and 17 controls were included, the former group being younger ((20(5.5) vs 23(1) years, p = 0.003). During steady-state standing SBP was higher as compared to controls (β: 6.853, CI: (0.713 12.993), p = 0.029). Patient data trended toward lower steady-state HR (β: -5.262, CI:(-11.201 0.677), p = 0.081), together with a larger peak-to-trough difference (β: 7.212, CI:(1.329 -15.754), p = 0.096). Conclusion These results tend to support the hypothesis and previous literature suggesting the presence of autonomic hyper-reactivity in patients with syncope, presenting as an exaggerated peripheral circulatory response to standing. Understanding the pathophysiology of VVS can help us improve its assessment and develop better treatment pathways for these patients. Abstract Figure.
