In this cross-sectional, observational study, the association between lethargy and vagal tone was analyzed in thirteen low-risk preterm infants. Infants underwent behavioral assessment and vagal tone measurement indexed by high-frequency heart-rate variability (HF-HRV). A lower vagal tone cluster was associated with greater lethargy (p = .05), reduced handling (p = .003), excitability (p = .006), higher skin stress indicators (p = .13), and central nervous system stress indicators (p = .10) than cluster with a higher vagal tone cluster. A lower vagal tone could indicate autonomic nervous system dysregulation or immaturity, leading to neurobehavioral challenges, such as lethargy and further neurodevelopmental difficulties. ©The authors ©Informa UK Limited ©Developmental Neuropsychology.

Background The Polyvagal theory argues that behavioral modulation is a fundamental neurodevelopmental process that depends on autonomic regulation. Objective The present study aimed to assess sleep architecture in newborns with fetal growth restriction (FGR) using polysomnography as an indicator of Polyvagal theory. Methods We studied polysomnography recordings from 68 preterm infants, 34 with FGR and 34 born with appropriate growth for gestational age (AGA), who were matched according to the corrected age for prematurity (CA). Total sleep time, arousals, the percentage of quiet sleep, active sleep, indeterminate sleep, and heart rate were compared between the groups. Linear multiple regression analyses were used to evaluate polysomnography data for the FGR and AGA groups.

Background: Fetal growth restriction (FGR) may be related to ethnicity. Additionally, ethnic groups experience adverse socioeconomic circumstances that increase FGR risk. However, the dearth of evidence of the interaction between socioeconomic factors and FGR highlights the need for additional research. Objective: To analyze the association between socioeconomic factors and FGR in Maya and non-Maya populations in Yucatan, Mexico. Methods: A total of 21,320 singleton births in 2017 in Yucatan were analyzed. The student’s t-test and the chi-square test were used to compare the means and proportions of maternal and perinatal variables between the FGR group and the birthweight appropriate for gestational age (AGA) group. Path analysis was performed to identify the direct and indirect effects of socioeconomic factors on FGR and mediators between predictors and FGR. © The Journal of Maternal-Fetal & Neonatal Medicine

Reconceptualizing the newborn: from “feed-sleep-clean” to behavioral state, stress, and self-regulation surveillance as the foundation of neurodevelopment
(Publicidad Permanyer, SLU, 2026)
Aldrete Cortez, Vania Rocío
;
Rendón-Macías, Mario Enrique
Dear Editor: Clinical routines often portray a newborn as someone who “feeds, sleeps, and is cleaned”; the medical add-on is “and is not ill.” This minimalist lens has long guided discharge and follow-up; however, it misses the display of an organized behavioral repertoire in neonates-states, transitions, and stress/self-regulation signals-that support later cognitive and socio-emotional development. Synactive theory frames early life as a dynamic interplay of autonomic, motor, state, attentional/interactive, and self-regulatory subsystems; according to this view, autonomic and motor organization, together with the behavioral state system, are foundational, while self-regulation integrates across these and other domains to organize subsequent development. When we treat infants as behaviorally competent beings, we change what we do: bedside care naturally incorporates state surveillance, reading of stress and self-regulation signals, and caregiver-infant synchrony as early markers of neurodevelopmental health. Contemporary neurobiological work has supported this integrated view by showing how wakeful, autonomic, and affective arousal are intertwined dimensions of a common regulatory system. © The authors © Boletín Médico del Hospital Infantil de México © Publicidad Permanyer.

Background The aim of this study was to analyze whether late-onset fetal growth restriction (FGR) alters regulatory capability in infants, and whether this can be detected using both the neonatal behavior assessment scale (NBAS) and brainstem auditory-evoked potentials (BAEP). Methods The diagnosis of FGR was made on Doppler examination in the third trimester of pregnancy. NBAS and BAEP measurement were performed at 1 month of corrected postnatal age.

Dear Editor Recently we read the papers by Neu et al. and Mörelius et al. [1], [2]. Their research documented cortisol co-regulation between mothers and infants during skin to skin care (SSC). Even though both studies' results exhibited lower cortisol levels, in one study with marginal differences [1] and in the other, with significant differences [2] between a group of premature infants SSC treated, as compared to the standard care (SC) group, only Mörelius et al. found cortisol co-regulation at four months of age, as an index of neuro-endrocrine effect of SSC [2]. ©Early Human Development

Habituation Alteration in Infants with Periventricular Echogenicity as an Indicator of Neurocognitive Impairment
(2021)

Habituation difficulties may suggest neurocognitive impairment. Periventricular echogenicity (PVE) potentially causes subtle damage that poses neuropsychological risk. Habituation was evaluated through heart rate and behavioral states in infants at 36–37 weeks of corrected age between control and PVE groups. PVE infants showed early alertness and abrupt changes in behavioral states. However, the comparison group could better regulate their states. Heart rate was significantly high and remained unchanged in the PVE group but decreased in the control group. Alterations during the habituation paradigm in PVE infants could be early indicators of neuropsychological risk impairment. Scope of early habituation assessment is discussed. © 2021 Taylor & Francis Group, LLC.

Congenital viral infections are believed to damage the developing neonatal brain. However, whether neonates exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show manifestations of such damage remains unclear. For neurodevelopment evaluation, general movement assessments have been shown to be effective in identifying early indicators of neurological dysfunction, including the absence of fidgety movements. This study compared the early motor repertoire by general movement assessment at three to five months of age in neonates who were or were not prenatally exposed to SARS-CoV-2 to determine whether infants prenatally exposed to SARS-CoV-2 are at risk of developing neurological disorders. Fifty-six infants, including 28 in the exposed group of mothers without vaccination who had no need for intensive care and likely had SARS-CoV-2 infection close to the time of pregnancy resolution and 28 infants in the nonexposed group, were videotaped to compare their detailed early motor repertoires, in which a motor optimality score-revised (MOS-R) was calculated using Prechtl’s method by using the chi-square or Mann–Whitney U tests. In the exposed group, 3 (11%) infants showed the absence of fidgety movements with a total MOS-R<14 points, and 3 (11%) other infants showed abnormal fidgety movements. Between groups, atypical body symmetry (p = 0.009) and MOS-R values were significantly lower (Z = -3.08, p = 0.002), with a large size effect (Cohen’s d = 0.97). The consequences of this new virus go beyond the health of the pregnant mother, and these consequences in some of the infants in the exposed group are likely not transitory because of the absence of fidgety movements between 3–5 months; thus, these babies are at increased risk of developing a serious neurological disorder.

Pregnant women have been considered a high-risk group for SARS-CoV-2 infection; the impact of the disease on the health of a mother and her child is still being studied. The emotional impact of the pandemic on pregnant women has been extensively studied. Emotional distress is proposed as a perspective to explain the emotional manifestations in women during this stage as something common rather than pathological. The objective of this study was to explore the emotional experience of women who tested positive for SARS-CoV-2 towards the end of their pregnancy, during the first and second waves of COVID-19 in Mexico. A qualitative study was carried out: 18 pregnant women with COVID-19 were interviewed. A thematic analysis of the data was performed, resulting in 3 main themes and 14 subthemes. The COVID-19-infected mothers-to-be experienced mild to moderate emotional distress. It was more intense for those with comorbidities. This distress was aggravated during obstetrical complications and comorbidities, as well as during COVID-19 and postpartum. The emotional distress was appeased by both the perception of medical care and social support. The emotional distress of pregnant women with COVID-19 requires emotional support to reduce its impact.
