For instance, too high oxygenation can easily induce lung injury, thus increasing inflammation and stressing the already immature CAP, whereas too low oxygenation can cause neurodevelopmental impairment and HIE (Rantakari et al., 2021).

It is thus noteworthy that, in the case of prone sleeping position, between the 2nd and 4th months after birth, both blood pressure and cerebral oxygenation seem to decrease, whereas there is a propensity for cortical arousal, maybe to counter the fall in pressure and oxygenation. Birt. One of such responses, able to perform homeokinetic adjustments, is the cholinergic anti-inflammatory pathway (CAP). (2017). Gynecol. doi: 10.1371/journal.pone.0068211, Stone, M. L., Tatum, P.

On the other hand, the ANS activity, as measured through heart rate variability (HRV)a non-invasive biomarker evaluating the variability of the time intervals between successive heartbeatsis affected by the developmental and health conditions of both fetus and infant. As excessive maternal cortisol, sGCs override the placenta mediator system (Sheng et al., 2020) and induce transient HRV modification toward sympathetic suppression (Multon et al., 1997; Senat et al., 1998; Subtil et al., 2003; Mulder et al., 2004; Schneider et al., 2010). Exposure to opioids prenatally could result in programming effects on stress response systems, leading also to long-term consequences (Conradt et al., 2018, 2019). Summary of the finding of the present review regarding ANS development and HRV. Am J Obstet Gynecol. Physiol. Immun. J. Obstet. Maternal acute and chronic inflammation in pregnancy is associated with common neurodevelopmental disorders: a systematic review. Although the induction of the hormone oxytocin has no cardiac repercussions, it can still influence the development of the vagus nerve and the ANS in the last hours of labor. The effect of magnesium sulfate tocolysis on the fetal biophysical profile. Pharmacological blocking agents were added to inhibit the effects of the sympathetic and/or parasympathetic systems.

Hypotension and uterine hypertonia, for instance, can create significant imbalances in the fHRV during epidural analgesia in labor (Lavin, 1982). It is worth noting that, from the 2nd trimester, HRV metrics can successfully estimate fetal autonomic brain age (Hoyer et al., 2012, 2013b, 2015, 2017, 2019). 14:612705. doi: 10.3389/fncel.2020.612705, Bornstein, M.

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. Volume and type of alcohol during early pregnancy and the risk of miscarriage. Although the fetal heart rate is related to fetal brain state, it is also affected by a number of other factors. In particular, we will study what events can interfere with the correct development of these two systems by analyzing the evidence from preclinical and clinical studies in this regard, with the aim of preventing potential complications with long-term consequences. Furthermore, the diminished vagal cardiovascular capacity to respond to hypoxic and hypercapnic states in the fetus, due to the abolishment of the serotonergic neurotransmission to cardiac vagal neurons caused by PNE, has been hypothesized as a likely link to SIDS (Kamendi et al., 2006, 2009). (1986). Nonetheless, the importance of ANS and vagus nerve regulation in fetal and neonatal development is still underrepresented (Sadler, 2012; Moore et al., 2016). Pediatr. J. Physiol. Biol. They do not make assumptions about linear relationships or require independent effects and they can consider trends over time. Frauenh. Sleep in late pregnancy predicts length of labor and type of delivery.

Currently, ANS development is usually assessed during the 3rd trimester, when vagus nerve myelination begins (Mulkey and du Plessis, 2018). Moreover, prophylactic antibiotic use during vaginal or cesarean delivery may indirectly lead to epigenetic changes in the fetus, with possible implications in the immune system and stress response (Tribe et al., 2018), consequently involving vagus nerve development and suggesting, therefore, the utility to consider potential alternative approaches (Ledger and Blaser, 2013).

Therefore, every possible procedure aimed to protect babies from harmful noises or to introduce positive sounds including the human voice, especially maternal voice (even recorded), and songs, can result in important neuroprotective effects (McMahon et al., 2012; Weber and Harrison, 2019). Neonatal Med. (2002). At 46 WGA the primitive diaphragm appears (Hill, 2021d) and, by 7 WGA, the four chambers of the heart have formed, thus connecting the heart to the aorta and the pulmonary trunk.

Is less noise, light and parental/caregiver stress in the neonatal intensive care unit better for neonates? Dis. Meas. As the nervous system of the fetus develops, around 3639 WGA a different fHRV pattern is detectable according to different acoustic stimuli, as for example human speech (Lecanuet et al., 1992; Krueger and Garvan, 2019). Scand. As newborns spend most of their time sleeping, ANS development correlates also with sleep development, with quiet sleep (absence of movements and slow rhythmic breathing) characterized by PNS predominance and active sleep (myoclonic twitching, facial, eye, and head movements, and irregular heart and breath rates) characterized by SNS predominance. Feedback may be negative or positive. Your doctor might ask you to stop pushing efforts, which causes fetal hypoxia to progress rapidly, in the second stage of labor.
