Comparing Full and Pre-Term Neonates' Heart Rate Variability in Rest Condition and during Spontaneous Interactions with Their Parents at Home.

BACKGROUND: Preterm neonates show decreased HRV compared to those at full-term. We compared HRV metrics between preterm and full-term neonates in transfer periods from neonate rest state to neonate-parent interaction, and vice versa. METHODS: Short-term recordings of the HRV parameters (time and frequency-domain indices and non-linear measurements) of 28 premature healthy neonates were compared with the metrics of 18 full-term neonates. HRV recordings were performed at home at term-equivalent age and HRV metrics were compared between the following transfer periods: from first rest state of the neonate (TI1) to a period in which the neonate interacted with the first parent (TI2), from TI2 to a second neonate rest state (TI3), and from TI3 to a period of neonate interaction with the second parent (TI4). RESULTS: For the whole HRV recording period, PNN50, NN50 and HF (%) was lower for preterm neonates compared to full-terms. These findings support the reduced parasympathetic activity of preterm compared to full-term neonates. The results of comparisons between transfer period simply a common coactivation of SNS and PNS systems for both full and pre-term neonates. CONCLUSIONS: Spontaneous interaction with the parent may reinforce both full and pre-term neonates' ANS maturation.

Giving Birth in Unpredictable Conditions: Association between Parents' COVID-19 Related Concerns, Family Functioning, Dyadic Coping, Perceived Social Support and Depressive Symptoms.

BACKGROUND: The way postpartum parents' COVID-19-related concerns are associated with the family environment, support resources and depressive symptoms areunder-investigated. METHODS: Two hundred and forty-three new parents (132 mothers, 111 fathers) completed self-report questionnaires within an 8-week period after birth. Parental concerns for COVID-19-related life changes were assessed with the COVID-19 Questionnaire, perceived social support with the Multidimensional Scale of Perceived Social Support, perceived family functioning with the Family Adaptability and Cohesion Evaluation Scales IV Package, dyadic coping behaviors with the Dyadic Coping Inventory and maternal/paternal postnatal depression with the Edinburgh Postnatal Depression Scale. RESULTS: (a) Higher levels of COVID-19-related concerns about daily life were associated with lower levels of family communication, satisfaction and increased depressive symptomatology in both parents, and with lower levels of family functioning in mothers; (b) Maternal health care COVID-19-related concerns were linked with lower levels of family communication, lower perceived social support and with an increase in maternal depressive symptoms; and (c) COVID-19-related concerns about neonate hospitalization were associated with increased maternal depressive symptoms. CONCLUSION: Τhese findings suggest that COVID-19-related concerns had a common negative effect on both postpartum mothers' and fathers' mental health and on certain aspects of family functioning.

COVID-19 Pandemic-Related Restrictions: Factors That May Affect Perinatal Maternal Mental Health and Implications for Infant Development.

This review aims to discuss the factors that may affect maternal mental health and infant development in COVID-19 pandemic condition. Toward this direction, the two objectives of this review are the following: (a) to discuss possible factors that may have affected negatively perinatal mental health through the pandemic-related restrictions; and (b) to present the implications of adversely affected maternal emotional wellbeing on infant development. We conclude that the pandemic may has affected maternal mental health with possible detrimental effects for the infants of the COVID-19 generation. We highlight the need for evidence-based interventions to be integrated within the health system for prenatal and postpartum care in an effort to promote maternal mental health and infant development.

Autonomic Nervous System Maturation and Emotional Coordination in Interactions of Preterm and Full-Term Infants With Their Parents: Protocol for a Multimethod Study.

BACKGROUND: There is limited knowledge on the physiological and behavioral pathways that may affect the developmental outcomes of preterm infants and particularly on the link between autonomic nervous system maturation and early social human behavior. Thus, this study attempts to investigate the way heart rate variability (HRV) parameters are related to emotional coordination in interactions of preterm and full-term infants with their parents in the first year of life and the possible correlation with the developmental outcomes of infants at 18 months. OBJECTIVE: The first objective is to investigate the relationship between emotional coordination and HRV in dyadic full-term infant-parent (group 1) and preterm infant-parent (group 2) interactions during the first postpartum year. The second objective is to examine the relationship of emotional coordination and HRV in groups 1 and 2 in the first postpartum year with the developmental outcomes of infants at 18 months. The third objective is to investigate the effect of maternal and paternal postnatal depression on the relation between emotional coordination and HRV in the two groups and on developmental outcomes at 18 months. The fourth objective is to examine the effect of family cohesion and coping on the relation between emotional coordination and HRV in the two groups and on developmental outcomes at 18 months. METHODS: This is an observational, naturalistic, and longitudinal study applying a mixed method design that includes the following: (1) video recordings of mother-infant and father-infant interactions at the hospital, in the neonatal period, and at home at 2, 4, 6, 9, and 12 months of the infants' life; (2) self-report questionnaires of parents on depressive symptoms, family cohesion, and dyadic coping of stress; (3) infants' HRV parameters in the neonatal period and at each of the above age points during and after infant-parent video recordings; and (4) assessment of toddlers' social and cognitive development at 18 months through an observational instrument. RESULTS: The study protocol has been approved by the Research Ethics Committee of the University of Crete (number/date: 170/September 18, 2020). This work is supported by the Special Account for Research Funds of the University of Crete (grant number: 10792-668/08.02.2021). All mothers (with their partners) of full-term and preterm infants who give birth between March 2021 and January 2022 at the General University Hospital of Crete (northern Crete, Greece) will be invited to participate. The researcher will invite the parents of infants to participate in the study 1 to 2 days after birth. Data collection is expected to be completed by March 2023, and the first results will be published by the end of 2023. CONCLUSIONS: Investigating the regulatory role of HRV and social reciprocity in preterm infants may have implications for both medicine and psychology.

Beyond the Words: Comparing Interpersonal Engagement Between Maternal and Paternal Infant-Directed Speech Acts.

The present study investigates the way infants express their emotions in relation to parental feelings between maternal and paternal questions and direct requests. We therefore compared interpersonal engagement accompanying parental questions and direct requests between infant-mother and infant-father interactions. We video-recorded spontaneous communication between 11 infant-mother and 11 infant-father dyads-from the 2nd to the 6th month-in their home. The main results of this study are summarized as follows: (a) there are similarities in the way preverbal infants use their affections in spontaneous interactions with their mothers and fathers to express signs of sensitivity in sharing knowledge through questions and direct requests; and (b) the developmental trajectories of face-to-face emotional coordination in the course of parental questions descend in a similar way for both parents across the age range of this study. Regarding the developmental trajectories of emotional non-coordination, there is evidence of a linear trend in terms of age difference between the parents' gender with fathers showing the steeper slope. The results are discussed in relation to the theory of intersubjectivity.

Comparing spontaneous imitation in grandmother-infant and mother-infant interaction: a three generation familial study.

The aim of this longitudinal and naturalistic study was to compare aspects of imitative exchanges in dyadic grandmother-infant and mother-infant interactions. Sixteen Cretan Greek infants were video-recorded in the course of spontaneous dyadic interactions with maternal grandmothers or with mothers at home from the 2nd to the 10th month of their life (N=48). The present study provides evidence that in interaction between grandmothers and infant grandchildren and between mothers and infants, there is similarity in the frequency, the structure, the direction of imitation, the kind of imitated acts, and the temporal patterns of the components of imitation. Infants' age was found to affect the developmental curve of grandmothers', but not mothers', imitative behavior. In the frame of the theory of innate intersubjectivity, we assume that similarity in these aspects of imitation may be related to invariant fundamental dimensions of Significant Other-infant communication ("kinematics" (temporal patterns), "physiognomics" (forms) and "energetics" (effort)). These similarities may have implications for both grandmothers' and infants' ability to regulate interpersonal challenges within an extended-family interactional context.
