Abstract Introduction It is not known whether the restorative nature of sleep mediates the effects of perceived stress on the autonomic nervous system (ANS).This study explored the relationships between stress and autonomic biomarkers, and aimed to assess potential mediation by sleep quality. Methods A secondary data analysis was performed using data from the Midlife in the United States (MIDUS, MIDUS II & Milwaukee). Multiple regression models examined the association between perceived stress using the Perceived Stress Scale (PSS) and two autonomic biomarkers-heart rate variability(HRV) (n=888) and urine catecholamines (n=1,058). The roles of sleep quality (using the Pittsburg Sleep Quality Index (PSQI)) and race/ethnicity were explored in post-hoc analyses. Results No statistically significant relationships were found between PSS and autonomic stress measures. However, perceived stress (b=0.09;p<0.01; 95% CI=0.06,0.13) and the covariate Likert stress scale at baseline (b=0.13;p=<0.04;95% CI=0.005,0.26) were significantly related to PSQI. Post hoc analyses explored racial differences. Baseline stress, PSS, depressive symptoms and PSQI scores were significantly higher in Blacks/African-Americans than Non-Hispanic Whites. Yet, Blacks/African-Americans had lower sympathetic responses (epinephrine means 1.56 vs 2.00;t=-4.82;p<0.01, norepinephrine means, 24.15 vs 27.30;t=3.14;p<0.01) and higher parasympathetic responses (lnHF, natural log of High Frequency HRV means 5.48 vs 4.75; t=6.17;p<0.01), compared to Non-Hispanic Whites. Conclusion Blacks/African-Americans and Non-Hispanic Whites had significant differences in their sleep quality and ANS biomarkers. Sleep quality may play a role in the effect of discrimination on mental and physical health. Different stress sources may lead to variable expression in biomarkers of autonomic tone. Future prospective studies incorporating longitudinal biomarkers and alternative statistical models will help elucidate the relationships among stress, sleep, and the pathways linking these factors to poor health, and effect targeted treatments.

Abstract Background Pectus excavatum (PE) negatively impacts psychological function, but its effect on autonomic nervous system (ANS) function has not been investigated. We evaluated ANS function following postural changes in patients with PE.Methods The participants were 14 healthy men (control group) and 20 men with PE (study group). Psychological function was assessed using the visual analog scale for pain, Brief Symptom Rating Scale-5, and Beck Depression Inventory-II. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). ANS regulation in response to postural change was measured in the supine position and immediately after sitting. All measurements were compared between the control and study groups at baseline and between the study groups before and after Nuss surgery.ResultsAt baseline, upon postural change, symptomatic activity increased in the control group (50.3% to 67.4%, p=0.035) but not in the study group (55.0% to 54.9%, p=0.654); parasympathetic activity decreased in the control group (49.7% to 32.6%, p=0.035) but not in the study group (45.1% to 45.1%, p=0.654); and overall ANS regulation increased in the control group (1.02 to 2.08, p=0.030) but not in the study group (1.22 to 1.22, p=0.322). In response to postural change after Nuss surgery in the study group, sympathetic activity increased (48.7% to 70.2%, p=0.005), parasympathetic activity decreased (51.3% to 29.8%, p=0.005), and overall ANS regulation increased (0.95 to 2.36, p=0.012).Conclusion ANS function in response to postural change is dysregulated in patients with PE, which improved after Nuss surgery.Trial registration: ClinicalTrials.gov, ID: NCT03346876, November 15, 2017, retrospectively registered,https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S0007KGI&selectaction=Edit&uid=U0003JZU&ts=2&cx=cstxeg

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a highly heterogeneous chronic and debilitating condition which effects millions of women and men in the United States. While primarily defined by urinary symptoms and pain perceived to be emanating from the bladder, IC/BPS patients frequently have co-occurring conditions and symptoms, many of which affect diverse body systems related to autonomic nervous system function. The impact on the autonomic system appears to stem from increased sympathetic innervation of the urinary tract, along with increased systemic sympathetic tone and decreased parasympathetic tone. Concurrent with these findings is evidence for destruction of peripheral sympathetic innervation to the sweat glands which may relate to small fiber polyneuropathy. It is unknown to what degree the wider alterations in autonomic function are also related to destruction/alterations in the small fibers carrying autonomic innervation. This potential nexus is an important point of investigation to better understand the unclarified pathophysiology of interstitial cystitis/bladder pain syndrome, the numerous co-occurring symptoms and syndromes, and for the identification of novel targeted therapeutic strategies.

Sleep apnea is highly associated with atrial fibrillation (AF), and both diseases are highly prevalent in the United States. The mechanistic underpinnings that contribute to their association remain uncertain, but numerous possible mechanisms have been proposed, including dysfunction of the cardiac autonomic nervous system (ANS). Studies have reported that apnea induces hyperactivity of the ANS, leading to increases in AF susceptibility. This review compiles the latest evidence on the role of the ANS in sleep-apnea-induced AF.

While the human body maintains homeostasis by altering the balance in the autonomic nervous, endocrine, and immune systems, a prolonged imbalance in these systems can result in physical and mental symptoms, including a decline in sleep quality and work efficiency. Euglenagracilis (Euglena) is a single-celled microalga with the properties of both plants and animals and contains abundant nutrients, such as vitamins, minerals, amino acids, and fatty acids, which have various beneficial health effects. This study evaluated the effects of Euglena intake on the mood states and stress coping under mental workload tasks, and subjective sleep quality. We assigned men and women aged 20 to 64 years to Euglena and placebo intake groups, and measured indices related to the autonomic nervous system, psychological states, and sleep quality together with the application of workload stress before food intake, and 4, 8, and 12 weeks after commencing intake. Euglena intake regulated the autonomic nervous system under a workload and improved psychological parameters and sleep conditions. These results indicate that the consumption of Euglena may regulate the balance of the autonomic nervous system during stress and may have a favorable effect on psychological status and sleep quality.

AbstractThis study explored the effect of long naps on handball-related performance and assessed the role of the cardiac autonomic nervous system in this process. Eleven male collegiate handball players performed a repeated sequential trial consisting of a 20-m consecutive turnaround run, 10-m run with a load, and shooting the ball into a target. Participants were allocated randomly and sequentially to have a short (20 minutes) nap, long (60 minutes) nap, or no nap. The Pittsburgh Sleep Quality Index was used to assess regular sleep quality. Subjective sleepiness before and after napping was measured using the Karolinska Sleepiness Scale. Heart rate variability was recorded to assess cardiac autonomic nervous function during napping. The Pittsburgh Sleep Quality Index score was correlated with shot accuracy only after long naps (ρ=0.636, r=0.048). A negative correlation was observed between the root mean square of successive differences and average load run time (ρ=−0.929, p<0.001). Long napping was associated with a significant benefit on performance in athletes with poor sleep quality, implying a role of the autonomic nervous system in this regard. Our findings indicate the effect of sleep quality on the endurance and resistance of handball players.
