The placental microbiota seems to display an evolutionary pattern during pregnancy and appears to be diversified in the various areas of the placenta (Aagaard et al., 2014; Cao et al., 2014; Pelzer et al., 2017). doi: 10.1136/bmjopen-2017-020031, Herry, C.

Nonetheless, when used correctly, the temperature can also help newborns to correctly develop: indeed, therapeutic hypothermia in newborns with 36 WGA in case of HIE can help reduce brain and injury brain inflammation, thus having positive effects on neurodevelopment (Massaro et al., 2017; Lemyre and Chau, 2018). Physiol. Korean J. Pediatr. Furthermore, ANS alterations in newborns can lead to neurological dysfunctions including cerebral palsy at 2 years of age (Dimitrijevi et al., 2016). Maternal plasma levels of oxytocin during physiological childbirth a systematic review with implications for uterine contractions and central actions of oxytocin. At about 1820 WGA, rapid eye movements (REM) can be detected (Borsani et al., 2019) as well as quiet and active sleeping states (Dereymaeker et al., 2017), although fetal behavioral states do not show particular coherence with ANS tone (Brndle et al., 2015). Fetal Neonatal Ed. Sci. The clinical goal of electronic fetal monitoring is to identify fetuses with increased risk of hypoxic injury so that intervention can avoid adverse outcome without also causing excessive numbers of unnecessary interventions. J. Obstet. Umbilical cord blood gases were: pH 6.88, PCO2 114, PO2 10, bicarbonate 15, base excess (-) 20. Autonomic nervous system impairment occurring in utero due to congenital heart disease, chronic hypoxemia, fetal growth restriction, acidemia, the trial of labor, bacterial, and viral infections or maternal factors can lead to labor complications (even death) and prematurity (Mulkey and du Plessis, 2018). Am. Infant stress reactivity and prenatal alcohol exposure. (1992). Circulation 130, 10031008. During labor, however, the nervous system is highly vulnerable to injuries due to hypoxia, energy deprivation, or oxidative stress (Morton and Brodsky, 2016; Mulkey and du Plessis, 2018; Mulkey et al., 2021).

Neurosci. (2010). During labor, the recommended fetal heart rate assessment interval for auscultation is every A. (2018). Factors that modulate fetal anaerobic reserve are myocardial glycogen stores, placental exchange capacity and chronic hypoxia. Pediatrics 139, S38S49. Breastfeed. Scand. Despite knowing that the CAN coordinates autonomic function and that left and right hemispheres modulate PNS and SNS tone, respectively (Mulkey et al., 2021), we have conflicting results on how the brain precisely controls ANS in newborns. Scand. Eur. 18, 175183. Gynecol. Off. doi: 10.1016/j.neuroscience.2016.07.026, Verspyck, E., and Sentilhes, L. (2008). Cholinergic anti-inflammatory pathway also plays a very important role in preventing and ameliorating NEC cases (Garzoni et al., 2013). 81, 909917. An important factor that is present in several cases of labor is epidural analgesia (Bautista and George, 2020). J. Acad. Exposure to SSRIs during the 3rd trimester is associated with blunted FMs and reactivity to VAS, as well as with reduced fHRV at 36 WGA (Oberlander et al., 2009; Nguyen et al., 2019). With the passing of the weeks, however, sex-specific differences in the sympathovagal balance start to be detected. Many viral infections, such as cytomegalovirus and other TORCH organisms or ZIKV infection, can lead to preterm birth and induce severe neurodevelopmental alterations in the fetus (Silasi et al., 2015; Vohr et al., 2017). Orthop. Obstet. J. Perinatol. Early development of sleep and brain functional connectivity in term-born and preterm infants. Burgio, E. (2015). (2020). Indeed, low cortisol levels could fail in regulating postnatal inflammation, e.g., necrotizing enterocolitis (NEC), which could induce cell death in the vagal brainstem centers (Fritze et al., 2014). 14:561186. doi: 10.3389/fnins.2020.561186, Christian, P., and Stewart, C.

(12), Over that last decade mounting evidence based on recent animal experimentation with very sensitive sensors and finer time resolution, has produced more information about hand chemoreceptors and their role in the production of decelerations. Molecular control of the neural crest and peripheral nervous system development. This stimulation reaches the brainstem, in particular the nucleus of the solitary tractthe main afferent nucleus of the vagus nervebut also other nuclei including the parabrachial ones, and then more cortical structures such as the hypothalamic paraventricular nucleus and the posterior insular cortex. Biol. Obstet. (2011). doi: 10.1016/j.jogc.2017.05.029, Jonas, W., Johansson, L. M., Nissen, E., Ejdebck, M., Ransj-Arvidson, A. Theyve concluded that the chances of fetal hypoxia remain low if repeated decelerations arent present and fetal heart tracing is otherwise normal. Furthermore, labor pain before CS helps prevent respiratory disorders and avoid umbilical cord acidemia, thus protecting the developing ANS (Senturk et al., 2015). Consequently, EFM fails to identify fetuses at risk of brain injury; this is because there is no clear correlation between fetal brain injury and acidemia (Westerhuis et al., 2007; Cahill et al., 2017). doi: 10.1093/pch/pxy028, Liu, H.

Fetal movement, in StatPearls (Treasure Island, FL: StatPearls Publishing). Sensors placed against the fetal cheek measure the reflected light in two specific wavelengths and from this the percentage of fetal oxygen saturation can be estimated. 162, 3541. (2006). Research on the ovine species, reproducing the conditions of human labor, is indeed leading to the discovery and evidence of different algorithms to prevent pathological complications (Frasch et al., 2011; Wang et al., 2014).

As the vagus nerve affects the body metabolism in a pleiotropic manner, such a review could help better understand the networks underlying this effect and how to harness them for improving fetal and neonatal health (Castel et al., 2020).

Short-term outcomes of newborns with perinatal acidemia who are not eligible for systemic hypothermia therapy. Board Fam. In addition, even mild inflammatory states in the mother might affect the placental conversion of maternal tryptophan to serotonin upstream of the fetal brain (Goeden et al., 2016). Lack of detection of a human placenta microbiome in samples from preterm and term deliveries. These changes were suggested to result from the effects of chronic hypoxiawhich ZIKV infection is known to causeon the interactions between the ANS and the cardiac pacemaker cell development which generates intrinsic HRV (Frasch et al., 2020a; Herry et al., 2021).

Moreover, an impairment in vagal balance, particularly a decreased tone, might be implicated in depression, anxiety, post-traumatic stress disorder, and schizophrenia (Thayer and Brosschot, 2005).

A., Cooper, E., Voon, V., Miles, K., and Critchley, H. D. (2013). The hallmark of a negative feedback loop is that it counteracts a change, bringing the value of a parametersuch as temperature or blood sugarback towards it set point. None of these guidelines specify what level of metabolic acidemia or degree of reliability they mean. doi: 10.5435/JAAOS-D-14-00248, Caspers Conway, K. M., Romitti, P. A., Holmes, L., Olney, R.

On the other side, properly covering incubators or using eye masks facilitate a quiet sleep state characterized by a stable respiratory function (Shiroiwa et al., 1986; Venkataraman et al., 2018).

Over the years a number of laboratories have studied the homeostatic regulation of both intrinsic neuronal excitability and synaptic strength ( Turrigiano, 2008 ), and clearly both kinds of mechanisms, separately and together, contribute in times and places to achieving network stability ( Pratt and Aizenman, 2007; Maffei and Fontanini, 2009 ).
