Tian Y, Inocencio IM, Sehgal A, Wong FY. Impact of Kangaroo mother care on autonomic cardiovascular control in foetal-growth-restricted preterm infants. Pediatr Res 2024:10.1038/s41390-024-03555-z. [PMID: 39242939 DOI: 10.1038/s41390-024-03555-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 08/25/2024] [Accepted: 08/27/2024] [Indexed: 09/09/2024]
Abstract
BACKGROUND Kangaroo mother care (KMC) is WHO-recommended for low-birth-weight infants, yet its impact on autonomic cardiovascular control in preterm foetal growth-restricted (FGR) infants remains unclear. We hypothesised that KMC would promote autonomic cardiovascular control, benefiting preterm FGR infants with reduced baseline autonomic function compared to appropriate for gestational age (AGA) infants. METHODS Autonomic control was assessed via heart rate variability (HRV) in low frequency (LF) and high frequency (HF) bands using spectral analysis. Preterm FGR (n = 22) and AGA (n = 20) infants were assessed for 30-min before and 60-min during KMC. Comparisons were made between FGR and AGA infants; and between infants with baseline HRV below and above median. RESULTS Overall, no significant HRV changes were observed during KMC for FGR or AGA infants compared to baselines. Infants with low baseline HRV LF showed increased HRV during KMC (p = 0.02 and 0.05 for the entire group and FGR group, respectively). This effect was absent in the AGA group regardless of baseline HRV. Infants with high baseline HRV had decreased HRV during KMC. CONCLUSIONS Infants with low baseline HRV, suggesting reduced autonomic control, are more likely to benefit from KMC with increased HRV. Further, this effect is stronger in FGR than AGA infants. IMPACT Kangaroo mother care (KMC) is WHO-recommended for low-birth-weight infants, yet its impact on autonomic cardiovascular control in preterm foetal growth-restricted (FGR) infants is unclear. Preterm infants with low baseline heart rate variability (HRV) are more likely to benefit from KMC and increase their HRV suggesting improved autonomic control. This effect is stronger in preterm FGR infants than those with appropriate growth for age.

Abstract
BACKGROUND Infants in neonatal intensive care units (NICUs) are exposed to frequent stressors that impact their neurodevelopmental outcomes. Parent presence and engagement are considered critical to improving infant outcomes, yet associations between cumulative NICU parent presence, engagement, and infant stress are infrequently examined. PURPOSE To examine associations between NICU infant stress and the amount (hours per week) or frequency (days per week) of parent presence and skin-to-skin care (SSC). METHODS A secondary analysis of a data set representing 78 NICU families was conducted. Infant acuity was measured using Neonatal Medical Index (NMI) scores. Parent presence and SSC data were collected from electronic medical records. Infant stress was measured using resting salivary cortisol levels collected at NICU discharge (median = 33 days of life). RESULTS More cumulative SSC was associated with lower discharge cortisol in NICU infants for SSC measured in hours per week (P = .03) or days per week (P = .05). Cumulative parent presence was not significantly associated with infant cortisol at discharge. Hierarchical regression analyses examining timing of parent presence supported a model including admission cortisol, NMI score, and parent presence during weeks 1 to 4 of life for explaining infant stress at discharge (R2 = 0.44, P = .004). Analyses examining timing of SSC supported a model including admission cortisol, NMI score, and frequency of SSC during week 1 for explaining infant stress at discharge (R2 = 0.21, P = .04). IMPLICATIONS FOR PRACTICE AND RESEARCH Early, frequent SSC to mitigate stress in NICU infants was supported. Results suggested that timing of parent presence impacts NICU infant stress; however, additional study is recommended.

Abstract
Background: Human milk diet, preferably mother's own milk (MOM) over donor milk (DM), is recommended for preterm infants. Expression of MOM in proximity to preterm infants, especially during or immediately after skin-to-skin contact (SSC), is associated with greater milk production. However, the correlation between SSC and MOM production during hospital admission in preterm infants has not yet been studied. Our study investigated the relationship between SSC and MOM production and consumption in preterm infants during the first postnatal month of life. Materials and Methods: This was a prospective cohort study. Mothers and their preterm infants born at <35 weeks by gestational age (GA) and eligible for SSC within the first 5 postnatal days were eligible for the study. Mothers were given a binder to document pumped breast milk volumes and SSC sessions. Pumped breast milk volumes, enteral feeding type and volume, and SSC duration and frequency were collected daily over the first 28 days of life, along with demographic, perinatal, and feeding data from electronic medical records (EMR). Results: Mean birth GA and weight were 30 ± 3 weeks and 1,443 ± 576 g, respectively. SSC duration was inversely correlated with GA and weight. The SSC duration was positively correlated with ingested MOM volume after correcting for birth GA. The SSC duration was predictive of increased volumes of pumped MOM. Conclusion: Our findings suggest that SSC duration is associated with improved MOM production and consumption. SSC can be a useful tool to increase MOM exposure and improve long-term health outcomes in preterm infants.

Abstract
Frameworks of emotional development have tended to focus on how environmental factors shape children's emotion understanding. However, individual experiences of emotion represent a complex interplay between both external environmental inputs and internal somatovisceral signaling. Here, we discuss the importance of afferent signals and coordination between central and peripheral mechanisms in affective response processing. We propose that incorporating somatovisceral theories of emotions into frameworks of emotional development can inform how children understand emotions in themselves and others. We highlight promising directions for future research on emotional development incorporating this perspective, namely afferent cardiac processing and interoception, immune activation, physiological synchrony, and social touch.

Abstract
INTRODUCTION The Newborn Infant Parasympathetic Evaluation (NIPE) index is an instrument that enables continuous, fast and objective assessment of neonatal discomfort. The aim of the study was to analyse changes in NIPE values after performance of blood draws and the factors involved in this variation. MATERIAL AND METHODS We conducted a prospective observational study. We included infants admitted to the neonatal intensive care unit between June and December 2021 who underwent blood draws. We recorded demographic data, aspects related to the procedure, the NIPE index and the heart rate at baseline and 1, 2, 3, 4, 5, 10 and 15 min after the procedure. RESULTS The study included 86 records for 49 patients. In the first 4 min after the procedure, there was a significant decrease in the NIPE index, with a maximum decrease of 22.8% relative to baseline and the nadir at 2.79 min. The decrease in NIPE values was greater in infants born preterm, male, with lower 5-min Apgar scores and following procedures that had been performed previously, after caesarean section or in the morning. There were no differences when the blood draw was obtained during kangaroo care. The correlation between the NIPE index and the heart rate was weak. CONCLUSIONS After a painful procedure, such as a blood draw, the NIPE monitor showed a significant decrease in the first 4 min, which was more pronounced in preterm infants, in repeated procedures or after caesarean delivery. The NIPE index could help identify infants experiencing acute procedural pain, complementing clinical rating scales.

Abstract
Osteopathic manipulative treatment (OMT) has been found to be effective in the context of premature infants. Nonetheless, no studies have investigated the immediate effects of OMT on heart rate variability (HRV). As altered HRV reflects poor or worsening newborn's clinical conditions and neurodevelopment, should OMT improve HRV fluctuations, it could become a relevant intervention for improving the care of preterm newborns. Therefore, this study aimed to evaluate whether OMT could affect HRV. The study was carried out at the Buzzi Hospital in Milan. From the neonatal intensive care unit, ninety-six preterm infants (41 males) were enrolled and were randomly assigned to one of two treatment groups: OMT or Static Touch. The infants were born at 33.5 weeks (±4.3) and had a mean birth weight of 2067 g (±929). The study had as primary outcome the change in the beat-to-beat variance in heart rate measured through root mean square of consecutive RR interval differences (RMSSD); other metrics were used as secondary and exploratory analyses. Despite the lack of statistically significant results regarding the primary outcomeand some study limitations, compared to static touch, OMT seemed to favor a parasympathetic modulation and improved HRV, which could reflect improvement in newborn's clinical conditions and development.

Abstract
Background: With advances in neonatal care, management of prolonged pain in newborns is a daily concern. In addition to ethical considerations, pain in early life would have long-term effects and consequences. However, its treatment remains inadequate. It was therefore important to develop an experimental model of long-lasting analgesia for neonatal research. Materials and Methods: Experiments were performed in six groups of rats with transdermal fentanyl 0, 3, 12, 50, 100, or 200 μg/kg/h from second postnatal day (P2) until weaning. Assessment of analgesia was carried out at P21, with behavioral scores (ranging from 0 to 3) using a 4% formalin test. Plasma levels of fentanyl were determined by UPLC/TQD at P22. Growth rate was investigated. Results: Fentanyl 100 and 200 μg/kg/h reduced scores of formalin-evoked behavioral pain. They increased time spent in pain score 0 (8 min 55 s and 6 min 34 s versus 23 s in controls) as in low pain scores 1 and 2, and decreased time in the most severe pain score 3 (19 min 56 s and 17 min 39 s versus 44 min 15 s). Fentanylemia increased in a dose-dependent manner from 50 μg/kg/h (2.36 ± 0.64 ng/ml) to 200 μg/kg/h (8.66 ± 1.80 ng/ml). Concerning growth, no difference was observed except weaker growth from P17 to P22 with 200 μg/kg/h. Clinically, we noticed no visible side effect from 3 to 100 μg/kg/h. Concomitantly, 200 μg/kg/h was responsible for ophthalmological side effects with appearance of corneal bilateral clouding in 90% pups. No difference was observed between male and female rats. Conclusion: Altogether, results indicate that transdermal fentanyl 100 μg/kg/h is an efficient therapeutic for long-lasting analgesia in lactating pups. This new model provides a useful tool for protection and welfare, and future opportunity for studying long-term health consequences of sustainable neonatal analgesia.

Abstract
Preterm infants, age-corrected for prematurity, score on average, 10 points lower on IQ tests than full-term infants tested at comparable ages. This review focuses on the potential contribution of the hypothalamus to cognitive neuro-regulatory development in preterm infants through its bidirectional neural connections with the prefrontal cortex and its neuroendocrine activity. It aims to clarify the central role of the hypothalamus in preterm high stress situations and in influencing cognitive development via its connectivity to the cerebral cortex. The review further evaluates epigenomic sensitivity to environmental inputs. Recent results suggest that an optimal range of DNA methylations (via a continuous process of decreasing levels of receptor methylations that are too high, and increasing levels that are too low) appears necessary in order to reach an adaptive level of receptor availability. Several studies have demonstrated amelioration of preterm infants' stress while in the Newborn Intensive Care Unit (NICUs) and following discharge. The authors postulate that feedback mechanisms and correction signals are the basis for a hypothalamic homeostatic modulating function, a "hypothalamic resistance response", which may account for the stress reduction brought about by in- and post-NICU early interventions and their results of promoting self-regulation and cognition.

Abstract
To date, there is no overarching proposition for the ontogenetic-neurobiological basis of self-regulation. This paper suggests that the balanced self-regulatory reaction of the fetus, newborn and infant is based on a complex mechanism starting from early brainstem development and continuing to progressive control of the cortex over the brainstem. It is suggested that this balance occurs through the synchronous reactivity between the sympathetic and parasympathetic systems, both which originate from the brainstem. The paper presents an evidence-based approach in which molecular excitation-inhibition balance, interchanges between excitatory and inhibitory roles of neurotransmitters as well as cardiovascular and white matter development across gestational ages, are shown to create sympathetic-parasympathetic synchrony, including the postnatal development of electroencephalogram waves and vagal tone. These occur in developmental milestones detectable in the same time windows (sensitive periods of development) within a convergent systematic progress. This ontogenetic stepwise process is termed "the self-regulation clock" and suggest that this clock is located in the largest connection between the brainstem and the cortex, the corticospinal tract. This novel evidence-based new theory paves the way towards more accurate hypotheses and complex studies of self-regulation and its biological basis, as well as pointing to time windows for interventions in preterm infants. The paper also describes the developing indirect signaling between the suprachiasmatic nucleus and the corticospinal tract. Finally, the paper proposes novel hypotheses for molecular, structural and functional investigation of the "clock" circuitry, including its associations with other biological clocks. This complex circuitry is suggested to be responsible for the developing self-regulatory functions and their neurobehavioral correlates.

Abstract
BACKGROUND Neonatal heart rate variability (HRV) is widely used as a research tool. However, HRV calculation methods are highly variable making it difficult for comparisons between studies. OBJECTIVES To describe the different types of investigations where neonatal HRV was used, study characteristics, and types of analyses performed. ELIGIBILITY CRITERIA Human neonates ≤1 month of corrected age. SOURCES OF EVIDENCE A protocol and search strategy of the literature was developed in collaboration with the McGill University Health Center's librarians and articles were obtained from searches in the Biosis, Cochrane, Embase, Medline and Web of Science databases published between 1 January 2000 and 1 July 2020. CHARTING METHODS A single reviewer screened for eligibility and data were extracted from the included articles. Information collected included the study characteristics and population, type of HRV analysis used (time domain, frequency domain, non-linear, heart rate characteristics (HRC) parameters) and clinical applications (physiological and pathological conditions, responses to various stimuli and outcome prediction). RESULTS Of the 286 articles included, 171 (60%) were small single centre studies (sample size <50) performed on term infants (n=136). There were 138 different types of investigations reported: physiological investigations (n=162), responses to various stimuli (n=136), pathological conditions (n=109) and outcome predictor (n=30). Frequency domain analyses were used in 210 articles (73%), followed by time domain (n=139), non-linear methods (n=74) or HRC analyses (n=25). Additionally, over 60 different measures of HRV were reported; in the frequency domain analyses alone there were 29 different ranges used for the low frequency band and 46 for the high frequency band. CONCLUSIONS Neonatal HRV has been used in diverse types of investigations with significant lack of consistency in analysis methods applied. Specific guidelines for HRV analyses in neonates are needed to allow for comparisons between studies.

Effects of Live Music Therapy on Autonomic Stability in Preterm Infants: A Cluster-Randomized Controlled Trial. CHILDREN 2021; 8:children8111077. [PMID: 34828790 PMCID: PMC8618386 DOI: 10.3390/children8111077] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 11/13/2021] [Accepted: 11/17/2021] [Indexed: 11/16/2022]
Abstract
Unbuffered stress levels may negatively influence preterm-infants’ autonomic nervous system (ANS) maturation, thus affecting neurobehavior and psycho-emotional development. Music therapy (MT) is an evidence-based treatment modality in neonatal care. When coupled with skin-to-skin care (SSC), it may reduce stress responses in both preterm infants and their parents and enhance family-centered care. Accordingly, we aimed to compare the effects of combined MT and SSC and SSC alone on ANS stabilization in preterm infants. In a single-center, cluster-randomized trial design, ten two-month time-clusters were randomized to either combined MT and SSC or SSC alone. Families of preterm infants were offered two sessions of the allocated condition in the NICU, and a three-month follow up session at home. The primary outcome variable was stabilization of the ANS, defined by change in the high frequency (HF) power of heart rate variability (HRV) during the second session. Secondary outcomes included other HRV measures, parent–infant attachment, and parental anxiety at each session. Sixty-eight families were included. MT combined with SSC improved infants’ ANS stability, as indicated by a greater increase in HF power during MT compared to SSC alone (mean difference 5.19 m2/Hz, SE = 1.27, p < 0.001) (95% confidence interval 0.87 to 2.05). Most secondary outcomes were not significantly different between the study groups. MT contributes to preterm-infants’ autonomic stability, thus laying an important foundation for neuro-behavioral and psycho-emotional development. Studies evaluating longer-term effects of MT on preterm infants’ development are warranted.

Part II: The clinical application of nonpharmacologic care for NAS/NOWS. Neurotoxicol Teratol 2021; 88:107032.

Abstract
There has been increasing emphasis on the importance of the development of self-regulatory capacities of the individual as the cornerstone of development. The caregivers' abilities to manage their own attention, emotions, physiology and behaviors influence the development of the child's self-regulatory and interactive capacities, and thereby their overall development. Newborns prenatally exposed to psychoactive substances and/or to other prenatal stressors such as maternal poor nutrition, increased maternal stress, trauma, difficult and/or impoverished environments, in tandem with genetic predispositions, can result in alterations to their neurodevelopment that predispose them to self-regulatory problems that can be expressed at any stage of life. The care of infants with Neonatal Abstinence Syndrome (NAS)/Neonatal Opioid Withdrawal Syndrome (NOWS) and their mother/caregiver is a window of opportunity to assess the regulatory and co-regulatory capacities of both, and to provide holistic interventions with the goal of empowering the mother/caregiver in their own self-knowledge/self-regulation capacities and their crucial role in promoting the healthy development of their children. Non-pharmacologic care for the infant with NAS/NOWS is the first line of treatment and of paramount importance. Yet, current approaches are based on a limited scope of infant functioning, and the scoring systems in current use do not result in individualized and specific non-pharmacologic care of the infant, which can result in excessive or insufficient medication and a lack of caregiver appreciation for the infant's strengths, difficulties and early development. The interventions described here are based on the infant's signs of dysregulation in four neurobehavioral subsystems that can be dysregulated by NAS/NOWS, the infant's adaptive or maladaptive responses to return to a regulated functioning, and the co-regulatory behaviors of the infant and the mother/caregiver. In Part I of this two-part series on re-conceptualizing non-pharmacologic care for NAS/NOWS we laid the foundation for a new treatment approach, one grounded in developmental theory and evidence-based observations of infant and interpersonal neurobiology. Here, in Part II, we outline actionable, individually tailored evaluations and approaches to non-pharmacologic NAS/NOWS treatment based on strategies to support the regulatory capacities and development of 4 key domains: 1) autonomic; 2) motor/tone; 3) sleep/awake state control; and 4) sensory modulation subsystems.

Abstract
Pain assessment in newborns and infants is challenging for clinicians. Although behavioral and behavioral-physiological scales are validated pain assessment instruments, their use in this age group has significant limitations. In this review, we summarize the methods currently available for assessing pain in neonates and infants. It is possible that these pain detection methods are also useful for assessing the quality of anesthesia and analgosedation in these populations. Further research should be aimed at confirming the usefulness of these tools in infants and identifying additional pain assessment options for clinical practice.

Abstract
BACKGROUND Early skin-to-skin care (SSC) has been shown to improve outcomes after preterm birth, including improved clinical stability and establishment of breastfeeding. Recent evidence suggests the most unstable infants get the most benefit, yet these infants are not consistently offered opportunities for SSC because of safety concerns and discomfort of the care team. PURPOSE To identify barriers and implement a multidimensional approach to increase SSC within the first 72 hours of life among infants born less than 28 weeks' gestation and less than 1,000 g in a Level IV university-based regional intensive care nursery. METHODS Using Institute of Healthcare Improvement quality improvement methodology, a multidisciplinary team identified barriers to SSC and developed targeted interventions, including a unit-specific protocol; widespread parent, staff, and provider education; and an infant readiness checklist. The primary outcome was the rate of SSC within 72 hours. The balancing measure was the rate of severe intraventricular hemorrhage (IVH). Data were collected from monthly chart review and analyzed with statistical process control charts. The aim was to increase SSC within 72 hours of birth from 7 percent to greater than 80 percent within 12 months for infants born less than 28 weeks' gestation or less than 1,000 g. RESULTS Between June 2017 and December 2019, there were 52 extremely preterm infants included in the project (15 preintervention and 37 postintervention). The rate of SSC within the first 72 hours increased from 7 to 84 percent. There has been no increase in any or severe IVH during the project period despite the increased rate of SSC. IMPLICATIONS FOR PRACTICE Implementation of multidimensional, multidisciplinary interventions for reducing barriers to early SSC in extremely preterm infants resulted in rapid adoption of SSC in the first 72 hours of life without increasing severe IVH in this high-risk population.

Abstract
Benefits of skin-to-skin contact (SSC) are documented but often delayed in the extremely preterm population due to medical complexity and staff misconceptions about safety. This quality improvement initiative was designed to increase SSC utilization among infants born before 29 weeks' gestation regardless of respiratory support by addressing nursing barriers inhibiting SSC. A pre-/postsurvey evaluated comfort level performing and perceived barriers to SSC utilization. Implementation consisted of an updated unit-specific SSC protocol and tailored education specific to identified barriers. Evaluation included SSC rates and maternal human milk usage in the first 30 days of life. In total, 81 patients (22-28 weeks, 370-1410 g) were included. SSC rates ranged from 3.3% to 17.7% at baseline and increased to 33.2% to 39.1% postintervention. Maternal human milk utilization increased above target (≥75%) postintervention for days 7 and 14, but declined towards baseline on days 21 and 30. A statistically significant increase was observed in nursing comfort level when performing SSC for intubated infants as well as infants with a peripherally inserted central catheter or umbilical venous catheter. SSC rates increased with infants younger than 29 weeks requiring intubation and central line management, possibly as a result of greater nursing comfort surrounding with SSC.

Abstract
Several studies have focused on neonatal maternal separation (MS) to investigate behavioural and neuroendocrine reactions to lack of contact, but only a few have focused on early separation in the first days or weeks after birth. This literature review investigates the vital importance of contact and touch by exploring how skin-to-skin contact (SSC) regulates stress in the mother-infant relationship. Various databases such as PubMed, Scopus, and ScienceDirect were searched for literature published between 2015 and 2020. From 1141 articles, 22 were declared eligible. The reviewed articles showed how SSC regulates child stress by biological indicators such as the autonomic nervous system (ANS), heart rate variability (HRV), cortisol, and oxytocin. This research concludes the importance of SSC for stress regulation, especially during the COVID-19 pandemic. With no research to date indicating a possible risk of neonatal COVID-19 transmission following SSC, SSC should continue to be practiced for all women, as recommended by the WHO.

Abstract
PURPOSE The Newborn Infant Parasympathetic Evaluation (NIPE) is a heart rate variability-based technology for assessing pain and comfort in neonates and infants under 2-years-old. This review aims to investigate the clinical utility of the NIPE. METHODS Two investigators screened Pubmed/Medline and Google Scholar for relevant studies, independently. One investigator extracted data, which were reviewed by a second investigator. RESULTS The NIPE was used during/after painful stimuli (6 studies), in the context of general anaesthesia (2 studies), and for comfort assessment (6 studies). A) Evaluation of procedural pain/distress: 2 studies reported that the mean-NIPE could be used for reliable monitoring of prolonged pain, and one study reported the association between instant-NIPE and pain after a stimulus but the instant-NIPE represents the NIPE average over 3 min. Two studies found no correlation between the NIPE and comfort behavior/pain scales, but they mainly differed in patients' gestational age and evaluation methodology. B) There are only 2 studies for the evaluation of nociception during surgery under general anaesthesia with contradictory results. C) Studies assessing neonates' comfort reported increased NIPE scores during skin-to-skin contact and during facilitated tucking associated with a human voice. No effect on NIPE scores of facilitated tucking during echocardiography was reported in preterm infants. One study reported significantly different NIPE scores with 2 surfactant therapy protocols. Overall, study populations were small and heterogeneous. CONCLUSION The results regarding NIPE's performances differ between studies. Given the limited number of studies and the heterogeneous outcomes, more studies are required to confirm the NIPE usefulness in the different clinical settings.

Abstract
BACKGROUND While providing various benefits, concerns about the potential risks of kangaroo mother care, or skin-to-skin contact (SSC), between mother and her preterm infant hinder its widespread implementation in some resource- rich countries. In neonates, salivary chromogranin A (s-CgA) is elevated upon exposure to stress, whereas the perfusion index (PI) is associated with hemodynamics and peripheral perfusion. Here, we investigated the effects of SSC on s-CgA and the PI in preterm infants. METHODS Twelve infants were enrolled in the study. Factors associated with baseline s-CgA were analyzed. Baseline s-CgA and the level after SSC were compared. Secreted IgA in the saliva was compared as the control. The PI before, throughout, and after SSC were compared. RESULTS Baseline s-CgA was significantly lower in infants who were supplemented with baby formula milk in addition to breast milk before SSC (n = 2) compared with those fed with their mother's breast milk alone (n = 10, P = 0.03). SSC significantly decreased s-CgA in babies who were fed breast milk only before SSC (n = 10, P = 0.01) but not in those supplemented with formula milk before SSC (n = 2). Secreted IgA in saliva was not affected by SSC. The PI was significantly elevated during SSC (P = .01). CONCLUSION Our data indicate that SSC can reduce s-CgA levels when combined with mother's breast milk and increase the PI in preterm infants, thereby providing additional evidence of the benefit of SSC.

Abstract
Neonatal intensive care units (NICUs) greatly expand the use of technology. There is a need to accurately diagnose discomfort, pain, and complications, such as sepsis, mainly before they occur. While specific treatments are possible, they are often time-consuming, invasive, or painful, with detrimental effects for the development of the infant. In the last 40 years, heart rate variability (HRV) has emerged as a non-invasive measurement to monitor newborns and infants, but it still is underused. Hence, the present paper aims to review the utility of HRV in neonatology and the instruments available to assess it, showing how HRV could be an innovative tool in the years to come. When continuously monitored, HRV could help assess the baby’s overall wellbeing and neurological development to detect stress-/pain-related behaviors or pathological conditions, such as respiratory distress syndrome and hyperbilirubinemia, to address when to perform procedures to reduce the baby’s stress/pain and interventions, such as therapeutic hypothermia, and to avoid severe complications, such as sepsis and necrotizing enterocolitis, thus reducing mortality. Based on literature and previous experiences, the first step to efficiently introduce HRV in the NICUs could consist in a monitoring system that uses photoplethysmography, which is low-cost and non-invasive, and displays one or a few metrics with good clinical utility. However, to fully harness HRV clinical potential and to greatly improve neonatal care, the monitoring systems will have to rely on modern bioinformatics (machine learning and artificial intelligence algorithms), which could easily integrate infant’s HRV metrics, vital signs, and especially past history, thus elaborating models capable to efficiently monitor and predict the infant’s clinical conditions. For this reason, hospitals and institutions will have to establish tight collaborations between the obstetric, neonatal, and pediatric departments: this way, healthcare would truly improve in every stage of the perinatal period (from conception to the first years of life), since information about patients’ health would flow freely among different professionals, and high-quality research could be performed integrating the data recorded in those departments.

Abstract
Infants admitted to neonatal intensive care units (NICU) require carefully designed risk-adjusted management encompassing a broad spectrum of neonatal subgroups. Key components of an optimal neuroprotective healing NICU environment are presented to support consistent quality of care delivery across NICU settings and levels of care. This article presents a perspective on the role of neonatal therapists-occupational therapists, physical therapists, and speech-language pathologists-in the provision of elemental risk-adjusted neuroprotective care services. In alignment with professional organization competency recommendations from these disciplines, a broad overview of neonatal therapy services is described. Recognizing the staffing budget as one of the more difficult challenges hospital department leaders face, the authors present a formula-based approach to address staff allocations for neonatal therapists working in NICU settings. The article has been reviewed and endorsed by the National Association of Neonatal Therapists, National Association of Neonatal Nurses, and the National Perinatal Association.

Abstract
BACKGROUND Infants in the neonatal intensive care unit (NICU) are exposed to many stressors. There is growing evidence that chronic stress early in life has long-term neurodevelopmental implications. Skin-to-skin care (SSC) is an intervention used to reduce stress in the NICU. CLINICAL QUESTION In premature infants in the NICU, what is the available evidence that SSC improves short-term physiologic stress outcomes compared with incubator care? SEARCH STRATEGY PubMed and CINAHL were searched for terms related to SSC, stress, physiology, and premature infants. Of 1280 unique articles, 19 were identified that reported on research studies comparing SSC with incubator care in the NICU and reported stress-related physiologic outcome measures. RESULTS Although there have been some mixed findings, the research supports that SSC improves short-term cardiorespiratory stress outcomes compared with incubator care. The evidence is clearer for studies reporting stress hormone outcomes, with strong evidence that SSC reduces cortisol and increases oxytocin levels in preterm infants. IMPLICATIONS FOR PRACTICE AND RESEARCH SSC is safe and has stress-reducing benefits. SSC should be considered an essential component to providing optimal care in the NICU. More research is needed to determine the timing of initiation, duration, and frequency of SSC to optimize the stress-reducing benefits. Future research should include the most fragile infants, who are most likely to benefit from SSC, utilize power analyses to ensure adequate sample sizes, and use sophisticated data collection and analysis techniques to more accurately evaluate the effect of SSC on infants in the NICU.

Cardiac interaction between mother and infant: enhancement of heart rate variability. Sci Rep 2019; 9:20019. [PMID: 31882635 PMCID: PMC6934483 DOI: 10.1038/s41598-019-56204-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Accepted: 12/09/2019] [Indexed: 02/05/2023] Open
Abstract
The vagal activity of infants is represented by heart rate variability (HRV) and associated with both growth and socioemotional development. The enhancement of an infant's vagal tone activity might be beneficial for development. This study explored whether HRV in infants aged 3-8 months can be enhanced by influencing HRV in mothers (40 dyads). The power of the low frequency (LF) component of maternal HRV was facilitated using slow-paced breathing. We investigated whether the change in maternal HRV affected the LF component in infants held by their mothers. In older infants (N = 14, 6-8 months) the LF power showed an increase during maternal paced breathing, whereas a delayed increase occurred after termination of maternal paced breathing in younger infants (N = 16, 3-5 months). These results show that the effects of maternal cardiac activity on the infant's HRV are age-dependent. This age-dependent reactivity of the infant's HRV could be due to the development of the inner model in infants which regulates physiological functions, including cardiac activity. This finding might help develop efficient methods for enhancing vagal nerve activity in infants.

Abstract
Worldwide, more than 400,000 infants are born each year with complex congenital heart disease (CCHD) requiring surgical intervention within the first months of life. Although improvements in perioperative care have resulted in increased rates of survival, more than half of infants with CCHD have neurodevelopmental impairments affecting subsequent educational achievements, job opportunities, and mental health. Brain maturity and impaired outcomes in infants with CCHD are similar to those of prematurely born infants. Developmentally supportive care, including foundational application of kangaroo care (KC), improves neurodevelopment in premature infants. Provision of developmentally supportive care with KC during the early hospitalization of infants with CCHD has the potential to similarly improve neurodevelopment. The purposes of the article are to describe common congenital heart defects, describe developmentally supportive care with an emphasis on KC, and to offer specific recommendations for KC and research in infants with CCHD.
