Suboptimal bonding impairs hormonal, epigenetic and neuronal development in preterm infants, but these impairments can be reversed

Incarceration Postpartum: Is There a Right to Prison Nurseries?

Rising rates of female incarceration within the United States are incompatible with the lack of federal standards outlining the rights of incarcerated mothers and their children. A robust body of evidence demonstrates that prison nurseries, programmes designed for mothers to keep their infants under their care during detainment or incarceration, provide essential and beneficial care that could not otherwise be achieved within the current carceral infrastructure. These benefits include facilitation of breastfeeding, bonding during a critical period of child development, and decreased recidivism rates for participants. Legal precedent exists to support the rights of the mother to continue to parent their child but remains in stark opposition to current prison infrastructure that could allow them to do so. Existing state policies also have inconsistent mechanisms for determining child eligibility and should move to centre decision-making on a case-by-case basis. This work will demonstrate that a just society, supported by law and ensuring maternal-child welfare supports the establishment of prison nursery programmes as a part of the existing right to healthcare for incarcerated individuals.

Skin-to-skin care (SSC) for term and preterm infants

Skin-to-skin care (SSC) is an important part of parent and infant care during the neonatal period and into infancy. SSC should be initiated immediately after birth and practiced as a standard of care in all settings, as well as in the home. There is strong evidence that SSC has a positive effect on breastfeeding and human milk feeding in both term and preterm infants, as well as on mortality, cardiopulmonary stability, and thermoregulation. SSC reduces pain and infant stress, enhances parent-infant bonding, has neurodevelopmental benefits, and has positive effects on parental mental health. The safety and feasibility of providing SSC has been established in term and preterm infants, and SSC is recommended as best practice for all infants. The benefits of SSC outweigh the risks in most situations, and despite challenges, care providers should implement procedures and accommodations to ensure that SSC occurs as a safe and positive experience for the parent, family, infant, and health care team. This statement includes all families as defined and determined by themselves, and recognizes that health communication, language, and terminology must be individualized to meet specific family needs by the health care team.

Les soins peau-à-peau chez les nourrissons à terme et prématurés

Les soins peau-à-peau (SPP) sont un aspect important des soins au parent et au nourrisson pendant la période néonatale et la première enfance. Ils doivent être entrepris immédiatement après la naissance et faire partie des soins standards dans tous les milieux, y compris à la maison. Selon de solides données probantes, les SPP ont un effet positif sur l'allaitement et l'alimentation par du lait humain, tant chez les nourrissons à terme que prématurés, de même que sur la mortalité, la stabilité cardiorespiratoire et la thermorégulation. Les SPP réduisent la douleur et le stress chez les nourrissons, accroissent l'attachement entre le parent et son nourrisson et ont des effets bénéfiques sur le neurodéveloppement de l'enfant ainsi que sur la santé mentale des parents. Le caractère sécuritaire et la faisabilité des SPP sont établis chez les nourrissons à terme et prématurés, et ces soins sont recommandés dans le cadre d'une pratique exemplaire auprès de tous les nourrissons. Les avantages des SPP sont supérieurs aux risques dans la plupart des situations, et malgré les défis qui y sont associés, les dispensateurs de soins devraient adopter des protocoles et prévoir des adaptations pour s'assurer que les SPP soient une expérience positive et sécuritaire pour le parent, la famille, le nourrisson et l'équipe soignante. Le présent document de principes s'adresse à toutes les familles, telles qu'elles se définissent et se déterminent elles-mêmes, et tiennent compte de l'importance de personnaliser la communication, le langage et la terminologie en matière de santé pour que l'équipe soignante réponde aux besoins particuliers de la famille.

Transferring an extremely premature infant to an extra-uterine life support system: a prospective view on the obstetric procedure

To improve care for extremely premature infants, the development of an extrauterine environment for newborn development is being researched, known as Artificial Placenta and Artificial Womb (APAW) technology. APAW facilitates extended development in a liquid-filled incubator with oxygen and nutrient supply through an oxygenator connected to the umbilical vessels. This setup is intended to provide the optimal environment for further development, allowing further lung maturation by delaying gas exposure to oxygen. This innovative treatment necessitates interventions in obstetric procedures to transfer an infant from the native to an artificial womb, while preventing fetal-to-neonatal transition. In this narrative review we analyze relevant fetal physiology literature, provide an overview of insights from APAW studies, and identify considerations for the obstetric procedure from the native uterus to an APAW system. Lastly, this review provides suggestions to improve sterility, fetal and maternal well-being, and the prevention of neonatal transition.

Conception and Development of the Warmth/Affection Coding System (WACS): A Novel Hybrid Behavioral Observational Tool for Assessing Parent-to-Child Warmth

A vast body of research and theory underscores the importance of parental warmth/affection (hereby 'warmth' and 'warmth/affection' are used interchangeably) as a distinct relational process that is fundamental to core developmental processes including parent-child attachment, socialization, emotion recognition and responsivity, and empathic development. The increasing focus on parental warmth as a viable transdiagnostic and specific treatment target for Callous-Unemotional (CU) traits highlights the critical need for a reliable and valid tool for measuring this construct within clinical contexts. However, existing assessment methods have limitations in their ecological validity, clinical utility, and the comprehensiveness of their coverage of core warmth subcomponents. In response to this clinical and research need, the observational Warmth/Affection Coding System (WACS) was developed to comprehensively measure parent-to-child warmth/affection. This paper chronicles the conception and development of the WACS, which adopts a hybrid approach of utilizing both microsocial and macro-observational coding methods to capture key verbal and non-verbal subcomponents of warmth that are currently underrepresented or poorly captured by existing assessment tools. Recommendations for implementation and future directions are also discussed.

[Telemedical support of feto-neonatal care in one region - Part II: Structural requirements and areas of application in neonatology]

Telemedical infrastructure for patient assessment, care and follow-up as well as interdisciplinary exchange can contribute to ensuring patient care that is close to home and meets the highest quality standards, even outside specialised centres. In neonatology, synchronous audio-visual communication across institutions has been used for many years, especially in the Anglo-American countries. Areas of application include extended neonatal primary care and resuscitation, specific diagnostic applications, e.g. ROP screening and echocardiography, as well as parental care, regular telemedical ward rounds and further training of medical staff, especially using simulation training. For the implementation of such telemedical infrastructures, certain organisational, medical-legal and technical requirements for hardware, software and structural and process organisation must be met. The concrete realisation of a telemedical infrastructure currently being implemented for the region of Eastern Saxony is demonstrated here using the example of the Saxony Center for feto/neonatal Health (SCFNH). Within the framework of feto-neonatal competence networks such as the SCFNH, the quality of medical care, patient safety and satisfaction in a region can be increased by means of a comprehensive, well-structured and established telemedical infrastructure.

Paternal postpartum depression, coparenting, and father-infant bonding: Testing two mediated models using structural equation modeling

BACKGROUND

Impaired father-infant bonding is a mental health issue that has been understudied. The current study aimed to examine the extent to which fathers' depression symptoms and coparenting relationship, respectively, are associated with infant bonding, as well as how these two variables mediate in the association with infant bonding.

METHODS

Cross-sectional data from 612 fathers of infants (0-24 months) were used in this study. Path analyses on two competing mediation models were used to examine the direct and indirect associations between fathers' depression symptoms, coparenting relationship, and infant bonding, after controlling for several known covariates.

RESULTS

Whether fathers reported depression symptoms (Model 1) or reported lower levels of coparenting relationships (Model 2), they also reported higher levels of impaired infant bonding, rejection and anger, and anxiety about care after controlling for the covariates. The analysis further found significant indirect associations between father depression symptoms and father-infant bonding via the coparenting relationship (Model 1) as well as significant indirect associations between the coparenting relationship and father-infant bonding via father depression symptoms (Model 2).

LIMITATIONS

The cross-sectional data cannot show causal links. Specific efforts were made to recruit fathers with depression symptoms, and therefore prevalence rates may appear skewed.

CONCLUSIONS

Decreasing depression symptoms and improving coparenting quality can potentially improve father-infant bonding. Fathers' depression symptoms and coparenting quality can be bi-directionally related in the association with father-infant bonding. Early detection and preventive treatments for paternal depression symptoms and coparenting are warranted.

The Role of Oxytocin in Abnormal Brain Development: Effect on Glial Cells and Neuroinflammation

The neonatal period is critical for brain development and determinant for long-term brain trajectory. Yet, this time concurs with a sensitivity and risk for numerous brain injuries following perinatal complications such as preterm birth. Brain injury in premature infants leads to a complex amalgam of primary destructive diseases and secondary maturational and trophic disturbances and, as a consequence, to long-term neurocognitive and behavioral problems. Neuroinflammation is an important common factor in these complications, which contributes to the adverse effects on brain development. Mediating this inflammatory response forms a key therapeutic target in protecting the vulnerable developing brain when complications arise. The neuropeptide oxytocin (OT) plays an important role in the perinatal period, and its importance for lactation and social bonding in early life are well-recognized. Yet, novel functions of OT for the developing brain are increasingly emerging. In particular, OT seems able to modulate glial activity in neuroinflammatory states, but the exact mechanisms underlying this connection are largely unknown. The current review provides an overview of the oxytocinergic system and its early life development across rodent and human. Moreover, we cover the most up-to-date understanding of the role of OT in neonatal brain development and the potential neuroprotective effects it holds when adverse neural events arise in association with neuroinflammation. A detailed assessment of the underlying mechanisms between OT treatment and astrocyte and microglia reactivity is given, as well as a focus on the amygdala, a brain region of crucial importance for socio-emotional behavior, particularly in infants born preterm.

Sensory-based interventions in the NICU: systematic review of effects on preterm brain development

BACKGROUND

Infants born preterm are known to be at risk for abnormal brain development and adverse neurobehavioral outcomes. To improve early neurodevelopment, several non-pharmacological interventions have been developed and implemented in the neonatal intensive care unit (NICU). Sensory-based interventions seem to improve short-term neurodevelopmental outcomes in the inherently stressful NICU environment. However, how this type of intervention affects brain development in the preterm population remains unclear.

METHODS

A systematic review of the literature was conducted for published studies in the past 20 years reporting the effects of early, non-pharmacological, sensory-based interventions on the neonatal brain after preterm birth.

RESULTS

Twelve randomized controlled trials (RCT) reporting short-term effects of auditory, tactile, and multisensory interventions were included after the screening of 1202 articles. Large heterogeneity was identified among studies in relation to both types of intervention and outcomes. Three areas of focus for sensory interventions were identified: auditory-based, tactile-based, and multisensory interventions.

CONCLUSIONS

Diversity in interventions and outcome measures challenges the possibility to perform an integrative synthesis of results and to translate these for evidence-based clinical practice. This review identifies gaps in the literature and methodological challenges for the implementation of RCTs of sensory interventions in the NICU.

IMPACT

This paper represents the first systematic review to investigate the effect of non-pharmacological, sensory-based interventions in the NICU on neonatal brain development. Although reviewed RCTs present evidence on the impact of such interventions on the neonatal brain following preterm birth, it is not yet possible to formulate clear guidelines for clinical practice. This review integrates existing literature on the effect of sensory-based interventions on the brain after preterm birth and identifies methodological challenges for the conduction of high-quality RCTs.

Mother-Infant Dyadic Synchrony in the NICU Context

BACKGROUND

Dyadic synchrony is a co-constructed social process relating to the back and forth interactions between mothers and infants that are strongly associated with neurodevelopment, self-regulation, and attachment. In the neonatal intensive care unit (NICU), this process may become interrupted because of the physiological state of the infant, the emotional state of the mother, and the physical environment of the NICU.

PURPOSE

In applying Feldman's Biobehavioral Model of Synchrony, this empirical review deconstructs the process of dyadic synchrony in the NICU context and provides a conceptual approach to guide both research and clinical practice.

METHODS

First, we examine the theoretical and empirical literature to explicate the primary structural and biophysiological components of synchrony and relate these constructs to the extant research on premature infants. Next, we synthesize the maternal, infant, and contextual factors that facilitate or inhibit the ontogenesis of dyadic synchrony in the NICU. The final section highlights the state of the science in dyadic synchrony in the NICU including gaps and recommendations for future research.

FINDINGS

An empirical review synthesis presents a visual conceptual framework to illustrate multiple processes that depict maternal, infant, and contextual influences of mother-infant synchrony in the NICU.

IMPLICATIONS FOR PRACTICE/RESEARCH

Despite the challenges posed to mother-infant relationships in the NICU, high-quality mother-infant interactions are possible, dyadic synchrony can emerge, and premature infants can develop secure attachments. Clinicians and researchers can apply this conceptual framework of mother-infant dyadic synchrony in the NICU to promote evidence-based research and clinical practice.

Neurobehavioral Phenotype and Dysexecutive Syndrome of Preterm Children: Comorbidity or Trigger? An Update

Premature birth is a worldwide public health priority. One in ten children is born before 37 weeks of gestational age and, in developed countries, survival rates without major neonatal morbidity are increasing. Although severe sequelae associated with these births have decreased, their neurobehavioral difficulties, often associated in multiple fields, remain stable but still widespread. These neurobehavioral difficulties hamper the normal development of academic achievements and societal integration and intensify the children's needs for rehabilitation during their preschool and academic years. Severe sequelae increase when gestational age decreases. This is even truer if the socio-cultural background is impeded by low income, education and language skills as compared with defined averages. However, moderate and/or minor neurocognitive and/or behavioral difficulties are almost identical for a moderate or a late preterm birth. Obtaining a better clinical description of neurobehavioral characteristics of those pretermly born, once they reach preschool age, is essential to detect behavioral issues as well as early specific cognitive difficulties (working memory, planning, inhibition, language expression and reception, attention and fine motor skills, etc.). Such information would provide a better understanding of the executive functions' role in brain connectivity, neurodevelopment and neuroanatomical correlation with premature encephalopathy.

Association of a Family Integrated Care Model With Paternal Mental Health Outcomes During Neonatal Hospitalization

IMPORTANCE

During newborn hospitalization in the neonatal unit, fathers often feel anxious and excluded from their child's caregiving and decision-making. Few studies and interventions have focused on fathers' mental health and their participation in neonatal care.

OBJECTIVE

To study the association of a family integrated care (FICare) model (in single family rooms with complete couplet-care for the mother-newborn dyad) vs standard neonatal care (SNC) in open bay units with separate maternity care with mental health outcomes in fathers at hospital discharge of their preterm newborn and to study whether parent participation was a mediator of the association of the FICare model on outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This prospective, multicenter cohort study was conducted from May 2017 to January 2020 as part of the fAMily Integrated Care in the Neonatal Ward Study, at level-2 neonatal units in the Netherlands (1 using the FICare model and 2 control sites using SNC). Participants included fathers of preterm newborns admitted to participating units. Data analysis was performed from January to April 2021.

EXPOSURE

FICare model in single family rooms with complete couplet-care for the mother-newborn dyad during maternity and/or neonatal care.

MAIN OUTCOMES AND MEASURES

Paternal mental health was measured using the Parental Stress Scale: NICU, Hospital Anxiety and Depression Scale, Post-partum Bonding Questionnaire, Perceived (Maternal) Parenting Self-efficacy Scale, and satisfaction with care (EMpowerment of PArents in THe Intensive Care-Neonatology). Parent participation (CO-PARTNER tool) was assessed as a potential mediator of the association of the FICare model with outcomes with mediation analyses (prespecified).

RESULTS

Of 309 families included in the fAMily Integrated Care in the Neonatal Ward Study, 263 fathers (85%) agreed to participate; 126 fathers were enrolled in FICare and 137 were enrolled in SNC. In FICare, 89 fathers (71%; mean [SD] age, 35.1 [4.8] years) responded to questionnaires and were analyzed. In SNC, 93 fathers (68%; mean [SD] age, 36.4 [5.5] years) responded to questionnaires and were analyzed. Fathers in FICare experienced less stress (adjusted β, -10.02; 95% CI, -15.91 to -4.13; P = .001) and had higher participation scores (adjusted odds ratio, 3.424; 95% CI, 0.860 to 5.988; P = .009) compared with those in SNC. Participation mediated the beneficial association of the FICare model with fathers' depressive symptoms (indirect effect, -0.051; 95% CI, -0.133 to -0.003) and bonding with their newborns (indirect effect, -0.082; 95% CI, -0.177 to -0.015).

CONCLUSIONS AND RELEVANCE

These findings suggest that the FICare model is associated with decreased paternal stress at discharge and enables fathers to be present and participate more than SNC, thus improving paternal mental health. Supporting fathers to actively participate in all aspects of newborn care should be encouraged regardless of architectural design of the neonatal unit.

The Impact of Prepartum Depression and Birth Experience on Postpartum Mother-Infant Bonding: A Longitudinal Path Analysis

INTRODUCTION

Negative effects of impaired postpartum mother-infant-bonding on mental health of mothers, their newborn children and subsequent child development are well documented. Previous research demonstrated an association between a negative birth experience and postpartum mental health affecting postpartum mother-infant bonding. This study investigates the extent to which prepartum depression and birth experience influence the postpartum mental health of mothers and their bonding toward their newborns, and whether these influences differ according to parity and self-reported prior mental health problems.

METHOD

Three hundred and fifty-four women (18-43 years; M = 30.13, SD = 5.10) filled in the Edinburgh Postnatal Depression Scale (EPDS), the Maternal-Fetal Attachment Scale (MFAS), Salmon's Item List (SIL) assessing the birth experience, and the Postpartum Bonding Questionnaire (PBQ) at pre- and postpartum; they were also asked about birth complications and parity status.

RESULTS

Primipara reported significantly more birth complications (p = 0.048), with path analysis confirming this result (p < 0.001). Birth complications were associated with a more negative rating of the overall birth experience (p < 0.001). Mothers with self-reported prior mental health problems had higher prepartum depression scores (p < 0.001) but did not differ in other variables from mothers without prior self-reported mental health problems. Differences in depression scores between mothers with self-reported prior mental health problems and those without vanished at postpartum assessment (p > 0.05). Path-analysis highlighted the key role of postpartum depression, which was the only significant predictor of postpartum impairment in maternal-child bonding (p < 0.001). Birth experience and prepartum depression scores exerted an indirect effect on postpartum maternal-child bonding, mediated by postpartum depression.

DISCUSSION

The present study demonstrates the relevance of prepartum mental health of expectant mothers, especially of those who self-report prior mental health problems. The results support that reducing mental health problems of pregnant mothers might contribute to a more positive birth experience and potentially reduce postpartum depressive symptoms. As postpartum depression is associated with impaired parent-child bonding, such targeted interventions could promote child development. Group differences between primiparous and multiparous mothers suggest that the birth experience may be an influential factor for postpartum mental health.

Family integrated care: very preterm neurodevelopmental outcomes at 18 months

OBJECTIVE

To examine whether the family integrated care (FICare) programme, a multifaceted approach which enables parents to be engaged as primary caregivers in the neonatal intensive care unit, impacts infant neurodevelopment and growth at 18 months' corrected age.

DESIGN/METHODS

Prospective cohort study of infants born <29 weeks' gestational age (GA) who participated in the FICare cluster randomised control trial (cRCT) and were assessed in the Canadian Neonatal Follow-Up Network (CNFUN). The primary outcome measure, Cognitive or Language composite score <85 on the Bayley-III, was compared between FICare exposed and routine care children using logistic regression, adjusted for potential confounders and employing generalised estimation equations to account for clustering of infants within sites.

RESULTS

Of 756 infants <29 weeks' GA in the FICare cRCT, 505 were enrolled in CNFUN and 455 were assessed (238 FICare, 217 control). Compared with controls, FICare infants had significantly higher incidence of intraventricular haemorrhage (IVH) (19.5% vs 11.7%, p=0.024) and higher proportion of employed mothers (76.6% vs 73.6%, p=0.043). There was no significant difference in the odds of the primary outcome (adjusted OR: 0.92 (0.59 to 1.42) FiCare vs Control) on multivariable analyses adjusted for GA, IVH and maternal employment. However, Bayley-III Motor scores (adjusted difference in mean (95% CI) 3.87 (1.22 to 6.53) and body mass index 0.67 (0.36 to 0.99) were higher in the FICare group.

CONCLUSIONS

Very preterm infants exposed to FICare had no significant difference in incidence of cognitive or language delay but had better motor development.

TRIAL REGISTRATION NUMBER

Participants in this cohort study were previously enrolled in a registered trial: NCT01852695.

Early discharge and hospital-assisted home care is associated with better neurodevelopmental outcome in preterm infants

AIMS

To compare hospital-assisted neonatal home care and standard hospital care for preterm newborns on neurodevelopment at 2 years corrected age, as well as duration of hospitalization, breastmilk rates, and readmissions before 1 year.

METHODS

This observational study enrolled 415 inborn neonates <34^{+ 6} weeks that received home care (2008 to 2015) in the French University Hospital of Toulouse and 3186 neonates from the national cohort of infants discharged in 2011 that received standard hospital neonatal care (EPIPAGE 2). Neurodevelopment at 2 years was assessed with the Ages and Stages Questionnaire-3 (ASQ-3).

RESULTS

At two years corrected age, infants in home care had 61% less risk of overall low ASQ ≤220 (OR = 0.4 [0.3-0.5], p < 0.001) and 31-80% less risk of low scores in four out of five domains compared to standard care. Home care was associated with shorter hospital stays (- 9 days; p < 0.001), higher breastmilk rates at final discharge (OR = 3.6 [2.8-4.6], p < 0.001 for singletons and OR = 2.3 [1.6-3.1], p < 0.001 for multiples), and more breastmilk feeding for at least six months (OR = 1.8 [1.3-2.3], p < 0.001 for singletons, OR = 3.6 [2.1-6.3], p < 0.001 for multiples). Readmissions also occurred less frequently with home care than with standard care, except for twins (OR = 0.7 [0.6-0.8], p < 0.001).

CONCLUSION

Hospital-assisted neonatal home care for preterm infants was associated with better neurodevelopment at 2 years corrected age, shorter duration of hospitalization, and higher rates of breastmilk feeding at 6 months.

Maternal speech decreases pain scores and increases oxytocin levels in preterm infants during painful procedures

Preterm infants undergo early separation from parents and are exposed to frequent painful clinical procedures, with resultant short- and long-term effects on their neurodevelopment. We aimed to establish whether the mother's voice could provide an effective and safe analgesia for preterm infants and whether endogenous oxytocin (OXT) could be linked to pain modulation. Twenty preterm infants were exposed to three conditions-mother's live voice (speaking or singing) and standard care-in random order during a painful procedure. OXT levels (pg/mL) in saliva and plasma cortisol levels were quantified, and the Premature Infant Pain Profile (PIPP) was blindly coded by trained psychologists. During the mother's live voice, PIPP scores significantly decreased, with a concomitant increase in OXT levels over baseline. The effect on pain perception was marginally significant for singing. No effects on cortisol levels were found. The mother's live voice modulated preterm infants' pain indicators. Endogenous OXT released during vocal contact is a promising protective mechanism during early painful interventions in at-risk populations.

Mapping the Field in Stress, Anxiety, and Postpartum Depression in Mothers of Preterm Infants in Neonatal Intensive Care

Objective: The main aim of this study was to describe and conduct a bibliometric analysis of the state of research on stress, anxiety, and postpartum depression in mothers of preterm infants in the Neonatal Intensive Care Unit. Background: Women affected by premature births are particularly exposed to mental health difficulties in the postpartum period. The desire to comprehend and the growing interest in research on stress, anxiety, and postpartum depression in mothers of preterm infants in neonatal intensive care have led to a substantial rise in the number of documents in this field over the last years. Thus, it makes it vital to regularly review the state of knowledge on this phenomenon in order to identify progress and constraints, to stimulate reflection, and to encourage progress in future research. Method: This study examined 366 articles published in the Scopus database (1976–2020). Keyword analysis was also used to identify hot research trends to be developed in future studies. This study complies with the PRISMA-Scr guidelines for quality improvement research in the EQUATOR network. Results: Our results reveal that research in this field is in a period of high production and allows this flourishing body of work to be organized into different periods, highlighting the most important themes. In such a way, our research enriches the lively field by presenting a comprehensive understanding of the field. Discussion: The key contribution of this study is the development of a conceptual map of research on stress, anxiety, and postpartum depression in mothers of preterm infants in neonatal intensive care units.

Potential Psychological and Biological Mechanisms Underlying the Effectiveness of Neonatal Music Therapy during Kangaroo Mother Care for Preterm Infants and Their Parents

Neonatal music therapy (MT) has become more accessible worldwide. Previous research suggests multiple benefits of MT for preterm infants and their caregivers; however, far too little attention has been paid to understanding the mechanisms of change in previous Neonatal Intensive Care Unit (NICU)-MT research so far. This perspective article describes potential mechanisms of MT interventions exposed during kangaroo mother care on the preterm infant's response (behavioral and physiological outcomes) and the mother-infant relationship. The paper focuses on the hypothalamic-pituitary-adrenal axis' role in stabilization of behavioral state, the autonomic nervous system's role in stabilization of physiologic state, as well as co-regulation as a potential mechanism for the developing of the parent-infant relationship. Mechanisms play a pivotal role in understanding variables related to the therapy course and well as in generating new knowledge regarding treatment susceptibility and optimizing resources. Understanding of the mechanisms of how interventions may lead to specific outcomes plays an important role in addressing the issue of improvement of currently available approaches of MT used in the NICU.

Defining Attachment and Bonding: Overlaps, Differences and Implications for Music Therapy Clinical Practice and Research in the Neonatal Intensive Care Unit (NICU)

Preterm birth and the subsequent hospitalization in the Neonatal Intensive Care Unit (NICU) is a challenging life event for parents and babies. Stress, anxiety, and depressive symptoms, limitations in holding or touching the baby, and medical complications during the NICU stay can negatively affect parental mental health. This can threaten the developing parent-infant relationship and might adversely impact child development. Music therapy in the NICU is an internationally growing field of clinical practice and research and is increasingly applied to promote relationship building between parents and babies. The two most commonly used concepts describing the early parent-infant relationship are 'attachment' and 'bonding'. While frequently used interchangeably in the literature, they are actually not the same and describe distinctive processes of the early relationship formation. Thus, it is important to discuss the overlaps and differences between attachment and bonding and the implications for music therapy clinical practice and research. Whereas providing examples and possible scenarios for music therapists working on either bonding or attachment, the distinction between both concepts is relevant for many health care professionals concerned with early parenting interventions in the NICU. This will hopefully lead to a more precise use of theory, and ultimately, to a more informed clinical practice and research.

Kangaroo father care: A pilot feasibility study of physiologic, biologic, and psychosocial measures to capture the effects of father-infant and mother-infant skin-to-skin contact in the Neonatal Intensive Care Unit

Robust literature supports the positive effects of kangaroo mother care (KMC) on infant physiologic stability and parent-infant bonding in the Neonatal Intensive Care Unit (NICU). Comparatively little is known about kangaroo father care (KFC) in the NICU, and KFC implementation has been limited. Our pilot feasibility study objective was to examine KFC effects on premature infants and fathers as compared to KMC. Parents of preterm NICU infants independently completed a 90-min Kangaroo Care (KC) session on consecutive days. Infant heart rate variability (HRV) and apnea/periodicity measures were compared (pre-KC to KC; KFC to KMC). Additionally, we assessed the feasibility of administering three psychosocial questionnaires to fathers and mothers in the NICU and after discharge. Ten preterm infants completed 20 KC sessions (33^4/7 -37^4/7  weeks post-menstrual age). Results demonstrated similar infant physiologic responses between KMC and KFC, including significant differences in measures of HRV (p < .05) between KC and non-KC periods. Eighty-eight percentage of questionnaires administered were completed, supporting the utilization of these instruments in future research of this population. If confirmed, these preliminary results identify an opportunity to objectively assess KFC effects, supporting the development of empirically based KFC programs benefitting NICU families.

Creative Music Therapy and Neurodevelopmental Outcomes in Pre-term Infants at 2 Years: A Randomized Controlled Pilot Trial

Impaired neurodevelopment is increasingly recognized as a major health issue in children born prematurely. Creative music therapy (CMT) intends to prevent and or reduce neurobehavioral deficits in pre-term infants using musical stimulation and socio-emotional co-regulation. We conducted a randomized, clinical pilot CMT trial to test feasibility and to examine long-term neurodevelopmental outcomes in pre-term infants (NCT02434224: https://clinicaltrials.gov/ct2/show/NCT02434224). Eighty-two pre-term infants were randomized either to CMT or standard care. A specially trained music therapist provided family-integrating CMT via infant-directed singing during hospitalization. Fifty-six infants underwent follow-up at 2 years of corrected age. No significant beneficial nor adverse effects of CMT were identified in routine clinical neurodevelopmental measures (Bayley-III Scales of Infant and Toddler Development and the standardized neurological examination). Longer term follow-up (5 years) and larger future studies are recommended to elucidate possible long-term effects of music in relation to more sensitive outcomes including executive function, detailed language processing and social-emotional development.

Creative Music Therapy with Premature Infants and Their Parents: A Mixed-Method Pilot Study on Parents' Anxiety, Stress and Depressive Symptoms and Parent-Infant Attachment

Premature birth is stressful for infants and parents and can adversely affect the parent–infant dyad. This mixed-methods pilot study evaluates whether creative music therapy (CMT) can alleviate anxiety, stress, and depressive symptoms in parents and support the bonding process with their infant. Sixteen parent couples were included. Ten couples were randomly allocated to the music therapy group (MTG) and six to the control group (CG). All couples completed psychological questionnaires measuring anxiety and depressive symptoms as well as an implicit measure of parent–infant attachment at two weeks postpartum (T1), at approximate neonatal intensive care unit (NICU) hospitalization halftime (T2), and two weeks after the infant had been discharged (T3). At T1 and T2, the parents additionally completed a questionnaire assessing the degree of stress they experienced at the NICU. Qualitative data were collected through a semi-structured, problem-centered interview with MTG parents at T3. The results of the quantitative analyses revealed reductions in anxiety levels from T1 to T2 (p = 0.002) as well as decreases in depressive symptoms from T2 to T3 (p = 0.022). No such changes were apparent in the CG. In fact, parental stress increased from T1 to T2 (p = 0.016). Significant increases in attachment across time were also observed within the MTG, but not in the CG. The qualitative inquiry confirmed that CMT can support the parent–infant relationship. Being in musical interaction evoked feelings of joy and relaxation in the parents and encouraged them to interact more profoundly with their infant. The results call for a more extensive powered follow-up study to further investigate CMT’s potential for parental well-being and parent–infant bonding.

Affective touch experiences across the lifespan: Development of the Tactile Biography questionnaire and the mediating role of attachment style

The sense of touch develops early in life and becomes a determinant aspect of our personal narratives, providing crucial information about the world around us and playing a prominent role in affective and social interactions. In this study we aimed to explore whether individual differences in touch experiences across the lifespan are related to adult attachment styles and to perceived touch deprivation. For this we first developed an instrument, namely the Tactile Biography, to quantify individual differences in affective touch experiences throughout life. Secondly, we performed a set of regressions models and a mediation analysis to investigate the role of attachment in relation to both the tactile history and perceived touch deprivation. We found that experiences of affective touch during childhood and adolescence seem to be closely associated with adult attachment styles and adult social touch experiences. Avoidant attachment appears to serve as a mediator in the relationship between earlier (childhood/adolescent) and later (adult) affective touch experiences, as well as between earlier affective touch experiences and perceived touch deprivation. These findings offer further support to existing literature, providing novel insights for the fields of social affective touch and attachment research.

Impact of Skin-to-Skin Parent-Infant Care on Preterm Circulatory Physiology

OBJECTIVES

To ascertain the impact of skin-to-skin care between parents and infants on cardiac function and cerebral blood flow in preterm infants.

STUDY DESIGN

We undertook a prospective study of 40 self-ventilating preterm infants at a quaternary center and assessed cardiac performance and cerebral blood flow. Assessments were carried out two hours before skin-to-skin care and then 60 minutes after skin-to-skin care (with the infant still on parent and turned supine).

RESULTS

Infants were 30.5 ± 0.6 weeks' gestational age and 1378 ± 133 g birthweight. Axillary temperature noted a nonsignificant increase during skin-to-skin care from 36.7 ± 0.07°C to 36.9 ± 0.07°C (P = .07). Cardiac contractility (right ventricular fractional area change [26.5% ± 0.3% vs 27.8% ± 0.4; P < .001] and tricuspid annular plane systolic excursion [0.73 ± 0.03 cm vs 0.77 ± 0.03 cm; P = .02]) increased significantly, coincident with decreased measures of pulmonary vascular resistance. An increase in systemic cardiac output was associated with increased cerebral blood flow and reduced middle cerebral artery resistive index (0.81 ± 0.02 vs 0.74 ± 0.02; P = .0001).

CONCLUSIONS

We documented a significant circulatory beneficial adaptation to a common neonatal practice. These findings align with previously documented physiologic benefits in cardiorespiratory stability and cardiac rhythm in preterm infants, and may be mediated through modulation of the autonomic nervous system.

Family Integrated Care for Preterm Infants

Parent-infant separation is a major source of stress for parents of hospitalized preterm infants and has negative consequences for infant health and development. Family Integrated Care (FICare) uses a strengths-based approach, based on family-centered care principles to promote parental empowerment, learning, shared decision making, and positive parent-infant caregiving experiences. Outcomes of FICare include increased self-efficacy upon discharge and improved parent-infant relationships and infant developmental outcomes. In this article, the authors describe the FICare model and emerging evidence regarding outcomes of FICare for infants and families and discuss challenges and opportunities in implementing and maintaining high-quality FICare.

Interactive sequences between fathers and preterm infants in the neonatal intensive care unit

AIMS

The first purpose of the study was to examine fathers' spontaneous communicative behavior with their preterm infants in the neonatal intensive care unit, and how father's and infant's behaviors affected each other. The second purpose was to examine any possible association between the fathers' and/or infants' characteristics and the quality of fathers' behaviors with their infants.

STUDY DESIGN/SUBJECTS/OUTCOME MEASURES

Father-preterm infant dyads (n=20) were assessed at 34-36 weeks postmenstrual age, during a spontaneous face-to-face communication with the infant placed in a heated cot in the NICU, and coded according to the Parent-Preterm Infant Coding System.

RESULTS

The presence of the father's Affiliative Behavior increased the occurrences of infant Gazing at the parent's face. In turn, infant gazing increased the occurrence of paternal Affiliative Behavior. The likelihood of infant's Gazing at the father's face was also significantly elicited by infrequent occurrences of paternal Affectionate Talk, co-occurring with Gazing at infant with Positive Facial Affect (but no Touch). With regard to the predictors of quality in father-infant interactions, we found a significant positive correlation between fathers' level of depressive symptomatology and fathers' Affiliative Behavior.

CONCLUSION

Our results show the of bidirectional sequential patterns of communication between fathers and preterm infants at 35 weeks postmenstrual age, and provide important information about the quality and modalities of paternal communication and their influence on infant behavioral states. From a clinical perspective, these results suggest that father-specific interventions designed to improve and sustain fathers' positive engagement with infants in the NICU should be pursued.

Multimodal Neurological Enhancement Intervention for Self-regulation in Premature Infants

BACKGROUND

The neonatal intensive care unit is often a noisy, overstimulating environment that disrupts infants' regulation of physiological and behavioral states and interrupts caregiver bonding; however, infants benefit from early intervention, including the use of multimodal neurological enhancement (MMNE) intervention to provide appropriate neurodevelopmental stimulation. No one has investigated whether it assists infants in self-regulation.

PURPOSE

The purpose of this retrospective longitudinal analysis was to examine the effect of a music therapy intervention, MMNE, on self-regulation of premature infants as measured by changes in heart rate (HR).

METHODS

A convenience sample of 60 premature infants received 486 MMNE sessions provided by a board-certified music therapist (MT-BC). Documentation, taken during routine clinical services, involved recording infant's HRs from the standard monitor for 3 minutes at baseline, during, and after a 20-minute MMNE intervention.

RESULTS

Infants' mean HRs were decreased during and post-MMNE sessions compared with baseline (P < .004 and P < .001, respectively). Furthermore, infants with a baseline HR above 170 had significant decreases both during and after the MMNE session (P < .001 for both time periods).

IMPLICATIONS FOR PRACTICE

Results of this study support the existing body of evidence showing the benefits of MMNE with premature infants. Based on our results, MMNE may help infants develop and demonstrate self-regulation as indicated by maintained HRs during and after the intervention as well as a lowered HR for infants who had high HRs prior to MMNE.

IMPLICATIONS FOR RESEARCH

Further research needs to be done regarding how infants process MMNE and its potential to aid sensory processing.

The evolution of family-centered care: From supporting parent-delivered interventions to a model of family integrated care

There is increasing recognition that parents play a critical role in promoting the health outcomes of low birthweight and preterm infants. Despite a large body of literature on interventions and models to support family engagement in infant care, parent involvement in the delivery of care for such infants is still restricted in many neonatal intensive care units (NICUs). In this article, we propose a taxonomy for classifying parent-focused NICU interventions and parent-partnered care models to aid researchers, clinical teams, and health systems to evaluate existing and future approaches to care. The proposed framework has three levels: interventions to support parents, parent-delivered interventions, and multidimensional models of NICU care that explicitly incorporate parents and partners in the care of their preterm or low birthweight infant. We briefly review the available evidence for interventions at each level and highlight the strong level of research evidence to support the parent-delivered intervention of skin-to-skin contact (also known as the Kangaroo Care position) and for the Kangaroo mother care and family integrated care models of NICU care. We suggest directions for future research and model implementation to improve and scale-up parent partnership in the care of NICU infants.

Pain, Parental Involvement, and Oxytocin in the Neonatal Intensive Care Unit

Preterm infants (PTI) typically experience many painful and stressful procedures or events during their first weeks of life in a neonatal intensive care unit, and these can profoundly impact subsequent brain development and function. Several protective interventions during this sensitive period stimulate the oxytocin system, reduce pain and stress, and improve brain development. This review provides an overview of the environmental risk factors experienced by PTI during hospitalization, with a focus on the effects of pain, and early maternal separation. We also describe the long-term adverse effects of the simultaneous experiences of pain and maternal separation, and the potential beneficial effects of maternal vocalizations, parental contact, and several related processes, which appear to be mediated by the oxytocin system.

Parent perspectives of neonatal tele-homecare: A qualitative study

INTRODUCTION

Neonatal homecare for preterm infants is a method of supporting families and monitoring infant growth in the home setting. Telehealth may be used to deliver specialist neonatal care remotely, using online communication methods. This study explored parental experiences with neonatal tele-homecare (NTH).

METHODS

Semi-structured interviews were conducted with 49 parents whose preterm infants had received NTH from a neonatal intensive care unit (NICU) in Denmark. Interview transcripts were analysed using Malterud's systematic text condensation.

RESULTS

Parents experienced NTH as a personalised method for linking to specialist staff in the NICU. NTH promoted the parent's role as the primary care provider, further strengthening the parent-infant relationship.

DISCUSSION

From the perspective of parents with preterm infants requiring specialist care, NTH is a useful method of supporting families in the home. Telehealth provides effective communication links with NICU specialists and encourages family-centred care.

Viewpoints of Parents and Nurses on How to Design Products to Enhance Parent-Infant Bonding at Neonatal Intensive Care Units: A Qualitative Study Based on Existing Designs

AIM

To investigate how product design can be used to improve parent-infant bonding in a neonatal intensive care unit.

BACKGROUND

Impaired parent-infant bonding is an inevitable consequence of premature birth, which negatively influences development. Products, systems, or services that support the bonding process might counter these negative influences.

METHOD

The first step was to trace existing products by performing a literature search in PubMed, the university library, and Google. The identified existing designs were then used in semistructured interviews with nurses and parents to get insights into their desires and recommendations for product design to enhance bonding. Interviews contained open questions and a multiple-choice questionnaire based on the literature search.

RESULTS

In total, 17 existing design types were used in interviews with 11 parents and 23 nurses. All nurses explicitly stated that practicality was the first criterion designs aimed at enhancing bonding definitely had to meet. All parents indicated that they would like to use a design to enhance bonding if that would contribute to their child's health and development. For both parents and nurses, the most valuable way to enhance bonding seemed to be products to improve Kangaroo care; however, their specific desires varied substantially. Therefore, seven recurring themes were defined, resulting in nine general recommendations and six opportunities intended to enhance parent-infant bonding.

CONCLUSION

This study provides design recommendations and opportunities based on parents' and nurses' expert opinions. Designing to enhance bonding is considered valuable; however, designs should match the stakeholders' desires and conditions.

Features of Heart Rate Variability Capture Regulatory Changes During Kangaroo Care in Preterm Infants

OBJECTIVE

To determine whether heart rate variability (HRV) can serve as a surrogate measure to track regulatory changes during kangaroo care, a period of parental coregulation distinct from regulation within the incubator.

STUDY DESIGN

Nurses annotated the starting and ending times of kangaroo care for 3 months. The pre-kangaroo care, during-kangaroo care, and post-kangaroo care data were retrieved in infants with at least 10 accurately annotated kangaroo care sessions. Eight HRV features (5 in the time domain and 3 in the frequency domain) were used to visually and statistically compare the pre-kangaroo care and during-kangaroo care periods. Two of these features, capturing the percentage of heart rate decelerations and the extent of heart rate decelerations, were newly developed for preterm infants.

RESULTS

A total of 191 kangaroo care sessions were investigated in 11 preterm infants. Despite clinically irrelevant changes in vital signs, 6 of the 8 HRV features (SD of normal-to-normal intervals, root mean square of the SD, percentage of consecutive normal-to-normal intervals that differ by >50 ms, SD of heart rate decelerations, high-frequency power, and low-frequency/high-frequency ratio) showed a visible and statistically significant difference (P <.01) between stable periods of kangaroo care and pre-kangaroo care. HRV was reduced during kangaroo care owing to a decrease in the extent of transient heart rate decelerations.

CONCLUSION

HRV-based features may be clinically useful for capturing the dynamic changes in autonomic regulation in response to kangaroo care and other changes in environment and state.

'There were more wires than him': the potential for wireless patient monitoring in neonatal intensive care

BACKGROUND

The neonatal intensive care unit (NICU) can be one of the most stressful hospital environments. Alongside providing intensive clinical care, it is important that parents have the opportunity for regular physical contact with their babies because the neonatal period is critical for parent-child bonding. At present, monitoring technology in the NICU requires multiple wired sensors to track each baby's vital signs. This study describes the experiences that parents and nurses have with the current monitoring methods, and reports on their responses to the concept of a wireless monitoring system.

METHODS

Semistructured interviews were conducted with six parents, each of whom had babies on the unit, and seven nurses who cared for those babies. The interviews initially focused on the participants' experiences of the current wired system and then on their responses to the concept of a wireless system. The transcripts were analysed using a general inductive approach to identify relevant themes.

RESULTS

Participants reported on physical and psychological barriers to parental care, the ways in which the current system obstructed the efficient delivery of clinical care and the perceived benefits and risks of a wireless system. The parents and nurses identified that the wires impeded baby-parent bonding; physically and psychologically. While a wireless system was viewed as potentially enabling greater interaction, staff and parents highlighted potential concerns, including the size, weight and battery life of any new device.

CONCLUSIONS

The many wires required to safely monitor babies within the NICU creates a negative environment for parents at a critical developmental period, in terms of physical and psychological interactions. Nurses also experience challenges with the existing system, which could negatively impact the clinical care delivery. Developing a wireless system could overcome these barriers, but there remain challenges in designing a device suitable for this unique environment.

Quality of attachment in infants less than 1500g or less than 32weeks. Related factors

BACKGROUND

Prematurity carries a high risk of mortality and sequelae, altering the bonding process and leading to repercussions in terms of attachment.

OBJECTIVE

To assess the type of attachment in children under 32weeks' gestational age (GA) or below 1500g, in hospitals where development-centred care has been implemented and to study the association between various types of attachment and certain neonatal and family characteristics.

METHOD

Children <1500g or <32weeks GA who were born or admitted before 48h of life to one of two hospitals in Madrid between January and December 2012 were candidates for the study. The type of attachment was assessed through the strange situation procedure (SSP). Attachment was classified according to three types: secure (B), avoidant (A), or resistant/ambivalent (C). Insecure attachment was considered to be A+C. Children were assessed at a corrected age of 2years using the Bayley III Scales and SSP. Data on the characteristics of the parents and children were collected.

RESULTS

A total of 59% (117/199) of the children <1500g or <32weeks GA born in 2012 in the two study hospitals were able to be evaluated. Secure attachment was found in 64% (75/117), avoidant attachment in 12.8% (15/117), and resistant/ambivalent in 23.1% (27/117). The children with secure attachment had a score of 107.6±16 in the cognitive area of the Bayley's Scale versus 98.8±18.8 in those with insecure attachment (p 0.007). Frequency of secure attachment at ≤26weeks GA was 23% (3/13) versus 69% (72/104) in children >26weeks GA (p 0.003).

CONCLUSIONS

Nearly two-thirds of the children studied presented secure attachment, which was associated with better cognitive development. The frequency of secure attachment is lower in the children born more preterm.

Pilot study demonstrates that salivary oxytocin can be measured unobtrusively in preterm infants

Aim

This study assessed the feasibility and obtrusiveness of measuring salivary oxytocin in preterm infants receiving Kangaroo care, because this is a period of maximal bonding or co‐regulation. We also analysed possible influential determinants, including maternal oxytocin.

Methods

The saliva of preterm infants and their mothers was collected prior to, and during, Kangaroo care using cotton swabs and pooled into vials until sufficient volumes were obtained to measure oxytocin levels using a radioimmunoassay. The obtrusiveness of the infants’ collections was measured with a Likert scale.

Results

Saliva was collected unobtrusively prior to, and during, 30 Kangaroo care sessions in 21 preterm infants. This resulted in three vials with sufficient volumes of before‐Kangaroo care saliva and three with during‐Kangaroo care saliva. Oxytocin was detectable in all six vials. The Kangaroo care duration and the intensity of the mother–infant interaction before and during Kangaroo care seemed to be the most important determinants, and these should preferably be standardised in any future trials.

Conclusion

Oxytocin was measured unobtrusively in the pooled saliva of preterm infants both before and during Kangaroo care and could therefore be investigated as a biomarker in future studies.
