Sleep, autonomic control, and preterm birth —complex interrelationships with important health consequences

Heart rate variability is now well-established as a means to assess autonomic nervous system (ANS) control by analyzing the beat-to-beat variability over time of consecutive heart beats. The R-R intervals are mathematically transformed and depicted as power spectra within different frequency domains. Low frequency reflects both sympathetic and parasympathetic activity, high frequency reflects parasympathetic activity, and total power reflects overall autonomic activity. These analyses have been applied to a wide range of clinical conditions, and investigators have studied maturation of ANS control in preterm and term infants, with some evidence of increased influence of the parasympathetic system early in life (Physiol Meas 2016;37:1436-46).

Abstract Ageing is associated with attenuated autonomic function. Transcutaneous vagal nerve stimulation (tVNS) improved autonomic function in healthy young participants. We therefore investigated the effects of a single session of tVNS (studies 1 and 2) and tVNS administered daily for two weeks (study 3) in volunteers aged ≥ 55 years. tVNS was performed using modified surface electrodes on the tragus and connected to a transcutaneous electrical nerve stimulation (TENS) machine. Study 1: participants (n=14) received a single session of tVNS and sham. Study 2: all participants (n=51) underwent a single session o...

If you're enjoying this, please visit our site for more inspirational articles. For centuries, people have contemplated and argued over the merits and flaws of the human condition. Philosophers and psychologists have theoretically and scientifically dissected elements of the human psyche to get a better understanding of who we are as a species, and why we do what we do. While much focus has been given to negative aspects of personal choices, I thought to put thi...

Abstract Insomnia is the most prevalent sleep disorder, particularly among middle and older aged adults, and is associated with a variety of negative health consequences, including higher risk for cardiovascular disease. Unfortunately, the mechanisms linking insomnia with cardiovascular risk remain largely unknown, thus limiting targeted therapeutic interventions. The hyperarousal hypothesis has attracted the most support, positing that insomnia is a result of multisystem over-activation, including sympathetic hyperactivity, which promotes wakefulness and blocks the occurrence of sleep at the desired time. The res...

Authors: Isobe Y, Nakatsumi Y, Sugiyama Y, Hamaoka T, Murai H, Takamura M, Kaneko S, Takada S, Takamura T Abstract Objective We aimed to identify obstructive sleep apnea syndrome (OSAS) severity indices reflecting the anthropometric and metabolic characteristics of patients with OSAS. Methods A total of 76 patients with OSAS underwent nasal continuous positive airway pressure (nCPAP). We also investigated the effects of nCPAP on OSAS-associated muscle sympathetic nerve activity (MSNA), risk for cardiovascular diseases, and insulin secretion and sensitivity. Results Among the OSAS severity indices, HbA1c was signifi...

Conclusions: For chronic insomnia insomniacs, LLLT appears to shorten the sleep latency, decrease the number of awakening events at night, and improve the sleep efficiency. PMID: 31312225 [PubMed]

We present herein two siblings with DM1, a thin elder brother and an obese younger sister with visceral fat accumulation. Although neither had voluntary symptoms related to respiratory dysfunction, their apnea-hypopnea indices revealed severe SAS and subsequent arterial blood gases studies showed hypercapnia as well as hypoxia, suggesting central nervous system involvement with peripheral respiratory dysfunction. Noninvasive positive pressure ventilation during sleep was started following pulmonary assessment. Respiratory function should be assessed in DM1 patients, even those free of respiratory symptoms, because respirat...

Authors: Tebbani F, Oulamara H, Agli A Abstract OBJECTIVES: Study weight gain in pregnant women according to the recommendations of the American Institute of Medicine (IOM 2009) and identify the associated factors with inadequate weight gain in pregnant women in Constantine (Algeria). MATERIALS AND METHODS: A prospective and longitudinal study of a cohort of 217 pregnant women aged 19 to 43 years was carried out during the entire period of pregnancy at antenatal consultation and monitoring centers in Constantine (Algeria) from December 2013 to July 2016. Their weight was measured in the first, second and third ...

CONCLUSION: Treatment of OSA in patients with systolic HF improves respiratory indices but does not have a favorable effect on sleep quality. While OSA per se was associated with an increase in sympathetic drive, APAP treatment was not associated with a reduction in sympathetic drive. After 6 months of treatment, there was even a trend towards additional increases in sympathetic drive in the APAP group. PMID: 31240541 [PubMed - as supplied by publisher]
