Parent-Infant Skin-to-Skin Contact and Stress Regulation: A Systematic Review of the Literature

Effects of kangaroo mother care restrictions during the COVID-19 pandemic on feeding and physiological parameters in preterm neonates: a cohort study

OBJECTIVE

This research investigates the impact of kangaroo mother care restrictions on feeding and physiological parameters in preterm newborns during the COVID-19 pandemic.

METHODS

A retrospective cohort design was used, including 169 preterm neonates born at 30-34 weeks of gestation, recruited from a Neonatal Intensive Care Unit in Denizli, Turkiye. The study compared a kangaroo mother care group (n=78) and a kangaroo mother care-restricted group (n=91). Data analysis was conducted using the chi-square test, Fisher's exact test, and t-test.

RESULTS

The average duration until the initiation of full oral feeding was shorter in the kangaroo mother care group (mean difference=4.58, 95%CI 0.61-8.43, p=0.020). Newborns in the kangaroo mother care-restricted group had a higher likelihood of reverting to gavage feeding (OR 6.59, 95%CI 2.98-14.58, p=0.000), and higher withdrawal rates (OR 3.36, 95%CI 1.59-7.09, p=0.001). Newborns in the kangaroo mother care group experienced significantly lower rates of apnea attacks (OR 3.29, 95%CI 1.52-7.09, p=0.002), tachycardia (OR 4.43, 95%CI 1.54-12.76, p=0.004), and desaturation (OR 3.43, 95%CI 1.70-6.93, p=0.000).

CONCLUSION

This study highlights the positive effects of kangaroo mother care on preterm newborns' feeding and physiological parameters. It is recommended that kangaroo mother care be consistently provided to all newborns, even during exceptional circumstances such as pandemics.

2-Brain Regulation for Improved Neuroprotection during Early Development (2-BRAINED): a translational hyperscanning research project

Introduction

Very preterm (VPT) birth is a major risk condition for child development and parental wellbeing, mainly due to multiple sources of stress (e.g., separation and pain exposure) during the neonatal intensive care unit (NICU) stay. Early video-feedback (VF) interventions proved effective in promoting VOT infants' development and parental wellbeing. Electroencephalography (EEG) hyperscanning allows the assessment of brain-to-brain co-regulation during live interaction between infants and parents, offering promising insights into the mechanisms behind the interactive benefits of early VF interventions.

Goals

This study aimed to compare indices of brain-to-brain co-regulation between dyads of full-term (FT) and VPT infants interacting with their mothers and investigate the effect of an early post-discharge VF intervention on the brain-to-brain co-regulation indices of VPT dyads.

Methods and analysis

VPT and FT dyads will be enrolled at birth, and the former will be randomly allocated to one of two arms: VF intervention or care as usual. Short-term effectiveness will be assessed through ratings of mother-infant interaction videotaped before and after the VF intervention or care as usual. Mothers of VPT and FT infants will report on their mental state, parenting stress and bonding, and infant temperament and sensory profile at 3 and 6 months (corrected age, CA). At 9 months CA, all dyads will participate in a lab-based EEG-hyperscanning paradigm to assess brain-to-brain co-regulation through phase-locking value (PLV) and other explorative indices.

Ethics and dissemination

This study was funded by the Italian Ministry of Health and received approval by the Ethics Committee of Pavia (Italy) and participating hospitals. Research findings will be reported in scientific publications, presented at international conferences, and disseminated to the general public.

Affective Touch in Preterm Infant Development: Neurobiological Mechanisms and Implications for Child-Caregiver Attachment and Neonatal Care

BACKGROUND/OBJECTIVES

Affective touch is crucial in infant development, particularly in regulating emotional, cognitive, and physiological processes. Preterm infants are often deprived of essential tactile stimulation owing to their early exposure to the external environment, which may affect long-term developmental outcomes. This review aimed to examine the neurobiological mechanisms of affective touch and highlight effective interventions, such as skin-to-skin contact (SSC) and kangaroo care (KC), to promote development in preterm infants.

METHODS

This review summarizes recent studies in the literature on affective touch, the role of C-tactile fibers, and the effects of tactile interventions in neonatal care. Studies were selected based on their relevance to the care and development of preterm infants, with a focus on physiological and neurodevelopmental outcomes. Key interventions, including SSC and massage therapy, are discussed in relation to their effectiveness in the neonatal intensive care unit (NICU).

RESULTS

The results suggest that affective touch, mainly through activation of tactile C-fibers, improves caregiver-infant bonding, reduces stress responses, and supports neurodevelopment in preterm infants. Interventions such as SSC and KC have also been shown to improve physiological regulation in these infants, including heart rate, breathing, and temperature control while promoting emotional regulation and cognitive development.

CONCLUSIONS

Affective touch is a key component of early development, particularly in preterm infants admitted to the NICU. Integrating tactile interventions such as SSC and KC into neonatal care practices may significantly improve long-term developmental outcomes. Future research should explore the epigenetic mechanisms underlying affective touch and further refine tactile interventions to optimize neonatal care.

Impact of a music intervention on heart rate variability in very preterm infants

AIM

Infants born very preterm spend their early postnatal life in a neonatal intensive care unit, where irregular and unpredictable sounds replace the structured and familiar intrauterine auditory environment. Music interventions may contribute to alleviate these deleterious effects by reducing stress and providing a form of environmental enrichment.

MATERIAL AND METHODS

This was an ancillary study as part of a blinded randomised controlled clinical trial entitled the effect of music on preterm infant's brain development. It measured the impact of music listening on the autonomic nervous system (ANS), we assessed heart rate variability (HRV) through high-resolution recordings of heart rate monitoring, at three specific postmenstrual ages in premature infants.

RESULTS

From 29 included subjects, 18 were assessed for complete HRV dataset, including nine assigned to the music intervention and nine to the control group. Postmenstrual age appeared to be the main factor influencing HRV from 33 weeks to term equivalent age. Further analyses did not reveal any detectable effect of music intervention on ANS response.

CONCLUSION

This study found that ANS responses were not modified by recorded music intervention in very preterm infants during wakefulness or sleep onset. Further research is warranted to explore other factors influencing ANS development in this population.

Elective extubation during skin-to-skin care in preterm newborns is safe and well-tolerated

AIM

To evaluate the safety and tolerance of elective extubations in preterm newborns (PNB) during skin-to-skin care (SSC) compared to those performed in an incubator.

METHODS

Retrospective observational study including 142 extubations in 93 PNB with gestational age (GA) <32 weeks and/or birth weight (BW) <1500 g performed during the first 2 months of life. Safety, tolerance and extubation success at 72 h were assessed.

RESULTS

The median GA was 25.4 weeks in the SSC group versus 26.6 weeks in the incubator group (p = 0.002). The median BW was 700 grams and 880 grams, respectively (p = 0.001). In total, 60 extubations (42.3%) were performed during SSC in 42 PNB and 82 in incubator in 69 PNB. No incidents related to extubation during SSC were recorded. The extubation success rate was 80% in SSC versus 79.3% in incubator (p = 0.915). Most failures occurred between 3 and 24 h after extubation. There were no observed differences in heart rate or FiO2 variations between the groups, nor in the need to escalate respiratory support at 24 h after extubation (SSC 15% vs. incubator 12.2%, p = 0.628).

CONCLUSION

Extubation during SSC is a feasible, safe and well-tolerated practice, while allowing PNB to experience the benefits from SSC.

Evaluation of the psychometric properties of the Turkish version of the Skin-to-Skin Contact Scale for nurses

RATIONALE

Skin-to-skin contact is the practice with the highest level of evidence that increases the growth, development, and healing rate of the newborn. Neonatal nurses are also the best practitioners of skin-to-skin contact.

AIMS

This study examined the psychometric properties of the Turkish version of the Skin-to-Skin Contact Scale for nurses.

METHODS

This descriptive, correlational, and cross-sectional study was carried out with 226 neonatal and pediatric nurses between July 2022 and July 2023. The data were collected using an online questionnaire, including a descriptive information form and a skin-to-skin contact scale for nurses. Data were analyzed by explanatory and confirmatory factor analysis, Cronbach's alpha, and item-total score analysis.

RESULTS

It was determined that the scale consisted of 20 items and four sub-dimensions and that those four sub-dimensions explained 53.01% of the total variance. All factor loads were higher than 0.30 in the explanatory and confirmatory factor analyses. All the fit indices were higher than 0.80, and the Root Mean Square Error of Approximation (RMSEA) was less than 0.080 in the confirmatory factor analysis. Cronbach's alpha was determined to be 0.89 for the total scale and greater than 0.70 for all sub-dimensions.

CONCLUSIONS

The Skin-to-Skin Contact Scale for nurses was determined to be a valid and reliable measurement tool for Turkish nurses. It is recommended that the scale be used regularly in clinics to determine nurses' attitudes towards skin-to-skin contact.

Infant emotion regulation in the context of stress: Effects of heart rate variability and temperament

Stressful events are inherently emotional. As a result, the ability to regulate emotions is critical in responding effectively to stressors. Differential abilities in the management of stress appear very early in life, compelling a need to better understand factors that may shape the capacity for emotion regulation (ER). Variations in both biologic and behavioural characteristics are thought to influence individual differences in ER development. We sought to determine the differential contributions of temperament and heart rate variability (HRV; an indicator of autonomic nervous system function) to infant resting state emotionality and emotional reactivity in response to a stressor at 6 months of age. Participants included 108 mother-infant dyads. Mothers completed a measure of infant temperament at 6 months postnatal. Mother and infant also participated in a standardized stressor (the Repeated Still Face Paradigm) at that time. Electrocardiographic data were acquired from the infant during a baseline resting state and throughout the stressor. Fast Fourier Transformation was used to analyse the high frequency (HF) domain of HRV, a measure of parasympathetic nervous system activity. Infant ER was measured via standardized coding of emotional distress behaviours from video-records at baseline and throughout the stressor. Severity of mothers' depressive symptoms was included as a covariate in analyses. Results of linear regression indicate that neither temperament nor HRV were associated significantly with an infant's emotional resting state, although a small effect size was found for the relationship between infant negative affectivity and greater emotional distress (β = 0.23, p = 0.08) prior to the stressor. Higher HF-HRV (suggesting parasympathetic dominance) was related to greater emotional distress in response to the stressor (β = 0.34, p = 0.009). This greater emotional reactivity may reflect a more robust capacity to mount an emotional response to the stressor when infants encounter it from a bedrock of parasympathetic activation. Findings may inform eventual markers for assessment of ER in infancy and areas for intervention to enhance infant management of emotions, especially during stressful events.

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.

Impact of Parent Presence and Engagement on Stress in NICU Infants

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.

Randomized Controlled Trial on the Effect of the Neonatal Nurse Navigator Program on Maternal Stress and Neonatal Cortisol Levels

OBJECTIVE

To assess the effect of the Neonatal Nurse Navigator Program (NNNP) compared to usual care on maternal stress and neonatal salivary cortisol level (SCL) in the NICU.

DESIGN

Randomized control trial.

SETTING

NICU in a tertiary health care hospital in Manipal, Udupi District, Karnataka, India.

PARTICIPANTS

Neonates between 34 and 36 weeks gestation and their mothers (N = 120 dyads).

METHODS

We used block randomization to assign dyads to the intervention or control group. We measured maternal stress using the Parental Stress Scale: Neonatal Intensive Care Unit, and we estimated neonatal stress by measuring SCLs within 24 hours of NICU admission and before discharge from the unit. We conducted a descriptive analysis on participant characteristics and reported maternal stress levels using means and standard deviations. We used the analysis of covariance change score test to determine the difference in maternal and neonatal stress levels between the intervention and control groups.

RESULTS

The NNNP group exhibited significantly lower maternal stress scores before discharge than the control group, and we observed reductions across all three subscales of the Parental Stress Scale: Neonatal Intensive Care Unit. Mean neonatal salivary cortisol levels were significantly lower in the interventional group than in the control group, F(1.117) = 24.03, 95% confidence interval [7.9, 18.6], p < .001.

CONCLUSION

Use of the NNNP reduced maternal stress SCLs in high-risk neonates by actively engaging mothers in the care of their neonates in the NICU. We recommend adoption of the NNNP model as a standard care policy in NICUs throughout India.

Increasing the Resilience of Mothers With Preterm Infant: The Effect of Kangaroo Mother Care

Objective

Having a preterm infant is a stressful experience for parents, especially for mothers. This study was conducted to identify the effect of kangaroo mother care on the resilience of mothers with preterm infant hospitalized in Neonatal Intensive Care Unit.

Materials and methods

In this randomized controlled trial study, 60 mothers with preterm infant hospitalized in Neonatal Intensive Care Unit were randomly selected and allocated to intervention and control groups (30 per group), in Fatemiyeh Hospital, Hamadan, Iran. Data collection tool included demographic information and Conner & Davidson Resilience Questionnaire (CD-RISC), which were completed by mothers before and after the intervention. Kangaroo Mother Care (KMC) as an intervention was run in at least one hour daily for a week in the intervention group. The mother-infant pairs in the control group only received conventional method of care (CMC).

Results

There was a significant increase in the total resilience score of the mothers in the KMC group (from 58.87±14.71 to 69.67±14.50) after intervention (P<0.001); however, resilience score decreased significantly in the mothers of CMC group (from 57.77±13.33 to 51.63±12.20).

Conclusion

Kangaroo mother care could increase the resilience of mothers of preterm infants. Therefore using this approach as a complementary, effective, Low-cost, non-invasive care is recommended to maintain and promote the health of mothers with preterm infant.

Maternal singing sustains preterm hospitalized newborns' autonomic nervous system maturation: an RCT

BACKGROUND

Premature birth is known to affect the newborn's autonomic nervous system (ANS) maturation, with potential short and long-term impact on their neurobehavioral development. The purpose of the study was to investigate the effects of maternal directed singing and speaking on the preterm infants' autonomic nervous system (ANS) maturation as measured by the heart rate variability (HRV) parameters.

METHODS

In this multi-center randomized clinical trial, 30 stable preterm infants (m = 29,6 weeks of gestational age), without any abnormalities were randomized into an intervention (16) or a control group (14). HRV was measured weekly, for a total of 80 recordings during hospitalization, as well as before and after each session of singing or speaking.

RESULTS

The intervention group showed a significant increase of the percentage value of HRV power in the high frequency range when compared to the control group (p = 0.044). More specifically, the maternal singing significantly increased the high frequency power and decreased the low/high frequency power ratio (p = 0.037).

CONCLUSIONS

The preterm infant's vagal activity significantly increased in the intervention group, potentially enhancing their ANS maturation. The effect is specifically evidenced in the singing condition.

IMPACT

Maternal singing affects the autonomic nervous system maturation of preterm hospitalized newborns in the NICU. No previous studies investigated how early vocal parental intervention can affect preterm infants developement, throught their autonomic nervous system maturation. Early Vocal Contact as an early intervention involving parents has a positive impact on preterm infant's development and it can be easily implemented in the care of preterm infants.

Daily skin-to-skin contact alters microbiota development in healthy full-term infants

The gut microbiota is vital for human body development and function. Its development in early life is influenced by various environmental factors. In this randomized controlled trial, the gut microbiota was obtained as a secondary outcome measure in a study on the effects of one hour of daily skin-to-skin contact (SSC) for five weeks in healthy full-term infants. Specifically, we studied the effects on alpha/beta diversity, volatility, microbiota maturation, and bacterial and gut-brain-axis-related functional abundances in microbiota assessed thrice in the first year. Pregnant Dutch women (n = 116) were randomly assigned to the SSC or care-as-usual groups. The SSC group participants engaged in one hour of daily SSC from birth to five weeks of age. Stool samples were collected at two, five, and 52 weeks and the V4 region was sequenced. We observed significant differences in the microbiota composition, bacterial abundances, and predicted functional pathways between the groups. The SSC group exhibited lower microbiota volatility during early infancy. Microbiota maturation was slower in the SSC group during the first year and our results suggested that breastfeeding duration may have partially mediated this relation. Our findings provide evidence that postpartum SSC may influence microbiota development. Replication is necessary to validate and generalize these results. Future studies should include direct stress measurements and extend microbiota sampling beyond the first year to investigate stress as a mechanism and research SSC's impact on long-term microbiota maturation trajectories.

Improving the Treatment of Neonatal Sepsis in Resource-Limited Settings: Gaps and Recommendations

Neonatal sepsis causes significant global morbidity and mortality, with the highest burden in resource-limited settings where 99% of neonatal deaths occur. There are multiple challenges to achieving successful treatment of neonates in this setting. Firstly, reliable and low-cost strategies for risk identification are urgently needed to facilitate treatment as early as possible. Improved laboratory capacity to allow identification of causative organisms would support antimicrobial stewardship. Antibiotic treatment is still hampered by availability, but also increasingly by antimicrobial resistance - making surveillance of organisms and judicious antibiotic use a priority. Finally, supportive care is key in the management of the neonate with sepsis and has been underrecognized as a priority in resource-limited settings. This includes fluid balance and nutritional support in the acute phase, and follow-up care in order to mitigate complications and optimise long-term outcomes. There is much more work to be done in identifying the holistic needs of neonates and their families to provide effective family-integrated interventions and complete the package of neonatal sepsis management in resource-limited settings.

Parents' comfort and staffs' working-environment when infants are sitting skin-to-skin: a randomised controlled trial comparing a recliner and a hospital bed

Skin-to-skin contact between parents and preterm infants is recommended because it has proven to be valuable for the infants' development and healing. However, it can be difficult to comply with this guideline and still ensure a good working environment for the staff.This randomised controlled trial compared a new recliner developed in collaboration with parents and staff with a hospital bed for use in neonatal and maternity care using parents' rating of own comfort/discomfort, self-reliance, and felt security, and the chair's/bed's functionality at two different days (Q1 and Q2) of hospitalisation. The physical work-environment was evaluated through a questionnaire to the staff.Ninety-seven parents and 53 health professionals participated. Parents had significantly lower discomfort, in the recliner at Q1 compared to the hospital bed. The staff had to twist and/or bend their back significantly less often when working at the recliner as compared to the hospital bed. Practitioner summary: Due to poor working environment, a participatory design project developed a new recliner that improved the possibility of infants having skin-to-skin contact with their parents. The recliner provided a better working-environment for the staff while focussing on improving comfort and self-reliance of the parents, as compared to a hospital bed.

Cohort profile: the U-BIRTH study on peripartum depression and child development in Sweden

PURPOSE

The current U-BIRTH cohort (Uppsala Birth Cohort) extends our previous cohort Biology, Affect, Stress, Imaging and Cognition (BASIC), assessing the development of children up to 11 years after birth. The U-BIRTH study aims to (1) assess the impact of exposure to peripartum mental illness on the children's development taking into account biological and environmental factors during intrauterine life and childhood; (2) identify early predictors of child neurodevelopmental and psychological problems using biophysiological, psychosocial and environmental variables available during pregnancy and early post partum.

PARTICIPANTS

All mothers participating in the previous BASIC cohort are invited, and mother-child dyads recruited in the U-BIRTH study are consecutively invited to questionnaire assessments and biological sampling when the child is 18 months, 6 years and 11 years old. Data collection at 18 months (n=2882) has been completed. Consent for participation has been obtained from 1946 families of children having reached age 6 and from 698 families of children having reached age 11 years.

FINDINGS TO DATE

Based on the complete data from pregnancy to 18 months post partum, peripartum mental health was significantly associated with the development of attentional control and gaze-following behaviours, which are critical to cognitive and social learning later in life. Moreover, infants of depressed mothers had an elevated risk of difficult temperament and behavioural problems compared with infants of non-depressed mothers. Analyses of biological samples showed that peripartum depression and anxiety were related to DNA methylation differences in infants. However, there were no methylation differences in relation to infants' behavioural problems at 18 months of age.

FUTURE PLANS

Given that the data collection at 18 months is complete, analyses are now being undertaken. Currently, assessments for children reaching 6 and 11 years are ongoing.

Implementing Guidelines for NICU Parent Presence: Effects on Parent and Infant Stress

BACKGROUND

Relationships between parents and infants are essential for mitigating stressors encountered in neonatal intensive care units (NICUs) and are supported by parent presence and engagement.

PURPOSE

The purpose of this study was to compare NICU parent and infant outcomes pre- and postimplementation of an intervention aimed at increasing parent presence and engagement in the NICU. This family-centered care intervention consisted of communicating specific guidelines for parent presence.

METHODS

Data related to parent presence, skin-to-skin care, and breastfeeding; parental stress; infant outcomes including weight gain, length of stay, feeding status at discharge, and stress; and unit-level outcomes were collected from a convenience sample of 40 NICU families recruited preimplementation and compared with data for 38 NICU families recruited postimplementation of specific guidelines for parent presence. To establish comparability of groups, infants were assigned scores using the Neonatal Medical Index.

RESULTS

Parent presence, engagement in skin-to-skin care, and breastfeeding rates were not significantly different between groups. Stress-related outcomes were significantly decreased in NICU mothers, fathers, and infants, and infant feeding outcomes were improved in the postintervention group.

CONCLUSIONS

Specific guidelines for parent presence may represent an invitation for parents to engage with their NICU infants and may positively impact parent and infant stress.

Effects of Maternal Stress on Breast Milk Production and the Microbiota of Very Premature Infants

Perinatal stress experienced by mothers of very premature newborns may influence the mother's milk and the infant's intestinal microbiota. This prospective study of mothers of very preterm infants fed with mother's own milk (MOM) was carried out in a tertiary hospital over a 2-year period. The assessment of maternal stress in 45 mothers of 52 very preterm newborns using the parental stress scale (PSS:NICU) revealed an inverse relationship between stress and MOM production in the first days of life (p = 0.012). The greatest contributor to stress was the one related to the establishment of a mother-child bond. Maternal stress was lower in mothers in whom the kangaroo method was established early (p = 0.011) and in those with a higher educational level (p = 0.032). Levels of fecal calprotectin (FC) decreased with the passage of days and were directly correlated with birthweight (p = 0.044). FC levels 7 days post-delivery were lower in newborns that received postnatal antibiotics (p = 0.027). High levels of maternal stress resulted in progressive decreases and increases in the proportions of Firmicutes and Proteobacteria species, respectively, over 15 days post-delivery, both in MOM and in fecal samples from premature newborns. These findings underscore the importance of recognizing and appropriately managing maternal stress in neonatal units, given its marked influence on both the microbiota of maternal milk and the intestinal microbiota of premature newborns.

Implementation of Kangaroo Care in a Pediatric Cardiac Intensive Care Unit

With supporting the best neurodevelopmental outcomes possible, the doctor of nursing practice project was constructed. An educational program was created for nursing staff discussing the importance of kangaroo care and how to safely facilitate it in the intensive care setting. Following the education completion, kangaroo care was implemented. Data were collected exploring barriers to implementation, discharge on maternal breast milk, and parental feedback.

The effects and process of the intervention "Individual Shantala Infant Massage" in preventive child healthcare to improve parent-child interaction: study protocol for a quasi-experimental study

BACKGROUND

Individual Shantala Infant Massage is an intervention that is offered by several Dutch Preventive Child Healthcare (PCH) organizations as optional preventive support, in addition to basic care as offered to all children. It targets vulnerable families and aims to enhance sensitive parenting and to reduce (effects of) parental stress. The intervention is carried out by a certified nurse. It consists of three structured home visits. Parents learn to massage their infant and receive parenting support. This study aims to investigate the effectiveness and the process of the intervention. The main hypothesis is that Individual Shantala Infant Massage leads to increased parental sensitive responsiveness, lower perceived and physiological parental stress, and improved child growth and development in the intervention group, compared to a control group where this intervention is not offered by PCH. Secondary research questions address effects on parenting confidence and parental concerns regarding the infant, the influence of background characteristics and the intervention process.

METHODS

The study is a quasi-experimental non-randomized trial. The aim is to include 150 infant-parent dyads in both the intervention and the control group. This takes into account possible attrition and missing data as 105 dyads with complete data per group are sufficient for analysis. All participants complete questionnaires at T0 (pre-test, child age between six-sixteen weeks), T1 (post-intervention, or ± four weeks after T0), and T2 (follow-up at five months). At T2, a hair tuft is cut from the parents' head to measure hair cortisol levels. Data on infant growth and development is obtained from PCH files. In the intervention group, additional data is collected to evaluate the intervention process: parents complete an evaluation questionnaire at T1, nurses keep semi-structured logbooks of intervention sessions and interviews are conducted with parents and professionals.

DISCUSSION

Study results can contribute to the evidence base of infant massage as applied in Dutch PCH, and can inform parents, PCH practitioners, policy makers and researchers both inside and outside the Netherlands on feasibility and effectiveness of the infant massage intervention as applied in this format and setting.

Factors associated with skin-to-skin contact less than 180 min/day in newborns weighing up to 1,800 g: multicenter study

This article aims to evaluate the factors associated with a skin-to-skin contact time <180 min/day in newborns weighing up to 1,800 g during neonatal hospitalization. Prospective observational cohort study conducted in neonatal units of reference for the Kangaroo Method in Brazil. Data from 405 dyads (mother/child) were analyzed from May 2018 to March 2020. Maternal and neonatal explanatory variables were collected from medical records and interviews. Skin-to-skin contact was recorded in forms posted at the bedside, filled out by parents and staff. The outcome variable was the mean time of skin-to-skin contact < 180 min/day. Hierarchical modeling was performed by Poisson regression with robust variance. The variables associated with the outcome were "without easy access to the hospital", "without previous knowledge of the kangaroo method" and "having had morbidities during pregnancy". Mothers without easy access to the hospital and who are unaware of the kangaroo method should be priority targets for health policies to develop strategies that promote greater exposure to skin-to-skin contact during the hospitalization period of their children.

Improved respiratory parameters with skin-to-skin contact in premature infants with bronchopulmonary dysplasia on NIV-NAVA

AIM

To determine if skin-to-skin contact (SSC) improved respiratory parameters in premature infants with evolving or established bronchopulmonary dysplasia (BPD) on non-invasive neutrally adjusted ventilator assist (NIV-NAVA).

METHODS

Premature infants (<32 weeks gestational age) with BPD on NIV-NAVA were studied. Continuous readings from the Edi catheter (modified nasogastric feeding tube inserted for NAVA ventilation) were compared: pre-SSC (baby in incubator) and end-SSC (just before end of SSC).

RESULTS

Sixty-five episodes of SSC were recorded in 12 premature infants with median gestational age at birth of 24.4 (23.1-27.0) weeks and birth weight of 642 (530-960) grams. Peak Edi (uV) in end-SSC 11.5 (2.7-38.7) was significantly lower compared to pre-SSC 15.8 (4.0-36.6), p < 0.001. P mean (cmH₂ O) was significantly lower in end-SSC 9.7 (7.3-15.4) compared to pre-SSC 10.3 (7.5-15.5), p = 0.008. Respiratory rate (breaths/min) was significantly lower in end-SSC 52.9 (31.1-78.1) compared to pre-SSC 53.4 (35.1-74.1), p = 0.031. There was no significant difference in inspired oxygen requirement or time on back-up mode in end-SSC 40.0 (22.1-56.1) and 5.9 (0.0-56.0) compared to pre-SSC 39.0 (26.0-56.1) and 5.1 (0.0-29.3), p = 0.556 and p = 0.853 respectively.

CONCLUSION

SSC improved respiratory parameters in premature infants with evolving or established BPD on NIV-NAVA.

Instruments to measure interaction of mothers and newborns: A systematic review

Interactions between newborns and their parents/primary caregivers are characterized by asymmetric and dependent relationships. This systematic review mapped, identified, and described the psychometric parameters, categories, and items of instruments used to assess mother-newborn interaction. Seven electronic databases were accessed in this study. Furthermore, this research included neonatal interaction studies describing instruments' items, domains, and psychometric properties while excluding studies that focused on maternal interactions and lacked items for assessing newborns. Additionally, studies validated with older infants that did not have a newborn in the sample were used for test validation, which is a criterion used to decrease the risk of bias. Fourteen observational instruments from 1047 identified citations were included that addressed interactions using varying techniques, constructs, and settings. Particularly, we focused on observational settings that assessed interactions with communication-based constructs in the context of proximity or distance as influenced by physical, behavioral, or procedural barriers. These tools are also used to predict risk behaviors in a psychological context, mitigate feeding difficulties, and conduct neurobehavioral assessments of mother-newborn interactions. The elicited imitation was also an observational setting. This study found that the most described properties in the included citations were inter-rater reliability followed by criterion validity. However, only two instruments reported content, construct, and criterion validity, as well as a description of an internal consistency assessment and inter-rater reliability. Finally, the synthesis of the instruments reported in this study can guide clinicians and researchers in selecting the most appropriate one for their own application.

Prevalence of essential newborn care in home and facility births in the Peruvian Amazon: analysis of census data from programme evaluation in three remote districts of the Loreto region

Background

Essential newborn care (ENC) covers optimal breastfeeding, thermal care, and hygienic cord care. These practices are fundamental to save newborn lives. Despite neonatal mortality remaining high in some parts of Peru, no comprehensive data on ENC is available. We sought to estimate the prevalence of ENC and assess differences between facility and home births in the remote Peruvian Amazon.

Methods

We used baseline data from a household census of rural communities of three districts in Loreto region, collected as part of the evaluation of a maternal-neonatal health (MNH) programme. Women between 15 and 49 years with a live birth in the last 12 months were invited to complete a questionnaire about MNH-related care and ENC. Prevalence of ENC was calculated for all births and disaggregated by place of birth. Adjusted prevalence differences (PD) were post-estimated from logistic regression models on the effect of place of birth on ENC.

Findings

All 79 rural communities with a population of 14,474 were censused. Among 324 (>99%) women interviewed, 70% gave birth at home, most (93%) without skilled birth assistance. Among all births, prevalence was lowest for immediate skin-to-skin contact (24%), colostrum feeding (47%), and early breastfeeding (64%). ENC was consistently lower in home compared to facility births. After adjusting for confounders, largest PD were found for immediate skin-to-skin contact (50% [95% CI: 38-62]), colostrum feeding (26% [16-36]), and clean cord care (23% [14-32]). ENC prevalence in facilities ranged between 58 and 93%; delayed bathing was lower compared to home births (-19% [-31 to -7]).

Interpretation

Low prevalence of ENC practices among home births in a setting with high neonatal mortality and difficult access to quality care in facilities suggests potential for a community-based intervention to promote ENC practices at home, along with promotion of healthcare seeking and simultaneous strengthening of routine facility care.

Efficacy of kangaroo mother care combined with neonatal phototherapy in newborns with non-pathological jaundice: A meta-analysis

Background

The kangaroo-mother care method (KMC) is a skin-to-skin contact-centered care approach with numerous benefits for neonates, but its impact on the treatment of jaundiced neonates is unknown. This study aimed to investigate the efficacy of KMC combined with neonatal phototherapy (NNPT) in treating neonates with non-pathological jaundice.

Methods

Relevant articles were searched in PubMed, Embase, Web of Science, and Cochrane Library databases from database establishment to April 2022. The outcomes included, without limitation, serum bilirubin levels, and duration of phototherapy.

Results

This meta-analysis included five studies (4 randomized controlled trials and 1 observational study) involving four hundred eighty-two neonates with non-pathological jaundice. The results showed that the group receiving KMC combined with NNPT had lower serum bilirubin at 72 h after intervention [weighted mean difference (WMD) = −1.51, p = 0.03], shorter duration of phototherapy [standard mean difference (SMD) = −1.45, p &lt; 0.001] and shorter duration of hospitalization (SMD = −1.32, p = 0.002) compared to NNPT group. There was no difference in peak bilirubin in both groups of neonates (WMD = −0.12, p = 0.62).

Conclusions

KMC combined with NNPT helped to treat non-pathological jaundice in newborns compared to NNPT alone.

Effects of daily full-term infant skin-to-skin contact on behavior and cognition at age three - secondary outcomes of a randomized controlled trial

BACKGROUND

Daily skin-to-skin contact (SSC) during early infancy fosters the long-term development of children born preterm. This is the first randomized controlled trial assessing the potential beneficial effects of daily SSC on executive functioning and socio-emotional behavior of children born full-term. Whether children of mothers who experienced prenatal stress and anxiety benefitted more from SSC was also explored.

METHODS

Pregnant women (N = 116) were randomly assigned to a SSC or care-as-usual (CAU) condition. Women in the SSC condition were instructed to perform one hour of SSC daily from birth until postnatal week five. Prenatal stress was measured with questionnaires on general and pregnancy-specific stress and anxiety completed by the mothers in gestational week 37. At child age three, mothers filled in questionnaires on children's executive functioning, and externalizing and internalizing behavior. Analyses were performed in an intention-to-treat (ITT), per-protocol, and dose-response approach. Netherlands Trial Register: NL5591.

RESULTS

In the ITT approach, fewer internalizing (95% CI = 0.11-1.00, U = 2148.50, r = .24, p = .001) and externalizing (95% CI = 0.04-2.62, t = 2.04, d = 0.38, p = .04) problems were reported in the SSC condition compared to the CAU condition. Multivariate analyses of variance did not show group differences on executive functioning. Additional analyses of covariance showed no moderations by maternal prenatal stress.

CONCLUSIONS

Current findings indicate that early daily SSC in full-term infants may foster children's behavioral development. Future replications, including behavioral observations of child behavior to complement maternal reports, are warranted.

Effect of the Kangaroo Mother Method after Preterm Delivery on Maternal Stress and Anxiety in the Context of the COVID-19 Pandemic-A Cohort Study

BACKGROUND

The kangaroo mother method (KMM) may benefit infants and mothers in many ways. However, few studies focused on its efficacy on maternal anxiety and stress, especially in the context of the COVID-19 pandemic.

OBJECTIVE

To examine the effect of the kangaroo mother method (KMM) on postnatal stress and anxiety in mothers of preterm infants in neonatal intensive care, in the context of the COVID-19 pandemic.

METHODS

A cohort study of two groups of 56 mother-infant dyads recruited from a neonatal intensive care unit was conducted. Two groups were compared in terms of the mean duration of KMM during the twelve days of the study: the intervention group (mean duration of more than ninety minutes per day) and the control group (less than ninety minutes). Maternal stress was measured using the Parental Stressor: Neonatal Intensive Care Unit (PSS: NICU) scale and STAI E/R questionnaire before and after intervention (KMM). Demographic and other maternal covariates were extracted from medical records. Daily NICU records were used to track the frequency and duration of KMM sessions.

RESULTS

Mothers of the intervention group scored lower on the PSS: NICU and STAI E/R, although no statistically significant differences were found (p > 0.05).

CONCLUSIONS

Contrary to research based on biological and physiological parameters in newborns or performed before the COVID-19 pandemic, the differences found in applying subjective scales in mothers in the context of the COVID-19 pandemic were not significant. Therefore, mothers' perception of physical contact with their preterm infants may not have been as positive due to their fear of transmitting COVID.

Effects of skin-to-skin contact on full-term infants' stress reactivity and quality of mother-infant interactions

Skin-to-skin contact (SSC) between mothers and their infants has beneficial effects in both preterm and full-term infants. Underlying mechanisms are largely unknown. This randomized controlled trial assessed whether daily SSC in full-term mother-infant dyads: (1) decreases infants' cortisol and behavioral reactivity to a mild naturalistic stressor, and (2) facilitates interaction quality between infants and mothers (i.e., improved maternal caregiving behavior and mother-infant adrenocortical synchrony). Pregnant Dutch women (N = 116) were recruited and randomly allocated to an SSC or care-as-usual condition. The SSC condition performed 1 h of SSC daily, from birth until postnatal week 5. In week 5, mothers bathed the infant (known mild stressor). Infant and maternal cortisol was sampled at baseline, 25 and 40 min after bathing, and infant and maternal behavior was rated. Results did not indicate effects of SSC on infant behavioral and cortisol reactivity to the bathing session. Similarly, no effect of SSC was found on maternal caregiving behavior and mother-infant adrenocortical synchrony. In conclusion, the findings provide no evidence that daily mother-infant SSC is associated with full-term infants' behavioral and adrenocortical stress reactivity or mother-infant interaction quality. Future studies should replicate these findings and unveil other potential mechanisms underlying beneficial effects of SSC.

Maintaining normal temperature immediately after birth in late preterm and term infants: A systematic review and meta-analysis

AIM

Prevention of hypothermia after birth is a global problem in late preterm and term neonates. The aim of this systematic review and meta-analysis was to evaluate delivery room strategies to maintain normothermia and improve survival in late preterm and term neonates (≥34 weeks' gestation).

METHODS

Medline, Embase, CINAHL, CENTRAL and international clinical trial registries were searched. Randomized controlled trials (RCTs), quasi-RCTs and observational studies were eligible for inclusion. Risk of bias for each study and GRADE certainty of evidence for each outcome were assessed.

RESULTS

25 RCTs and 10 non-RCTs were included. Room temperature of 23 °C compared to 20 °C improved normothermia [Risk Ratio (RR), 95% Confidence Interval (CI): 1.26, 1.11-1.42)] and body temperature [Mean Difference (MD), 95% CI: 0.30 °C, 0.23-0.37 °C), and decreased moderate hypothermia (RR, 95% CI: 0.26, 0.16-0.42). Skin to skin care (SSC) compared to no SSC increased body temperature (MD, 95% CI: 0.32, 0.10-0.52), reduced hypoglycemia (RR, 95% CI: 0.16, 0.05-0.53) and hospital admission (RR, 95% CI: 0.34, 0.14-0.83). Though plastic bag or wrap (PBW) alone or when combined with SSC compared to SSC alone improved temperatures, the risk-benefit balance is uncertain. Clinical benefit or harm could not be excluded for the primary outcome of survival for any of the interventions. Certainty of evidence was low to very low for all outcomes.

CONCLUSIONS

Room temperature of 23 °C and SSC soon after birth may prevent hypothermia in late preterm and term neonates. Though PBW may be an effective adjunct intervention, the risk-benefit balance needs further investigation.

Skin-to-skin contact to support preterm infants and reduce NICU-related stress

OBJECTIVE

Hospitalization in the neonatal intensive care unit (NICU) with numerous painful medical interventions, being separated from parents, leads to the high risk of chronic stress for preterm infants. Today, many NICUs use more appropriate developmental care and pain management, but the early and long-term outcomes of stress in these vulnerable infants require searching for more stress-reducing interventions in neonatal care. The objective of the study was to investigate how skin-to-skin contact (SSC) can influence the biologic stress levels in preterm infants in the NICU by assessing cortisol and oxytocin levels.

PARTICIPANTS AND METHODS

The study included 71 preterm infants with gestational age less than 34 + 0/7 weeks who were recruited from level III NICU. The overall design was a baseline-response design. Saliva and urine were collected before (baseline) and after skin-to-skin contact to measure salivary cortisol and urinary oxytocin by enzyme immunoassay method.

RESULTS

The infants' baseline hormonal status was represented by the following indicators: the level of salivary cortisol was 0.402 [0.227; 1,271] μg/dl, urinary oxytocin 48.88 [32.97; 88.11] pg/ml. There was a decrease in salivary cortisol levels to 0.157 [0.088; 0.351] μg/dl compared to baseline (p ˂ 0.001) with a simultaneous increase of the urinary oxytocin level -73.59 [45.18; 108.8] pg/ml (p = 0.028) in response to SSC.

CONCLUSION

Preterm infants in the NICU experience significant stress, characterized by hormonal imbalance: an increased level of the stress hormone cortisol and a decreased level of the anti-stress hormone oxytocin. Skin-to-skin contact helps to ameliorate the hormonal stress in preterm infants by activating the oxytocin release with simultaneous reduction of cortisol secretion.

Benefits of Kangaroo Mother Care on the Physiological Stress Parameters of Preterm Infants and Mothers in Neonatal Intensive Care

It is well documented that the stress of separation of mother and baby can lead to short-term physiological instability as well as neurological, sociological or psychological consequences that may last a lifetime. Objective: The goal was to estimate the effect of kangaroo mother care (KMC) on physiological and biochemical parameters of preterm infant stress and maternal stress in neonatal intensive care. Methods: The investigation involved 112 preterm infants. Two groups were compared according to the mean duration of KMC during 12 days of study: the KMC group (mean duration more than 90 min daily) and the control group (less than 90 min). Results: Kangaroo mother care for more than 90 min on average per day in preterm infants is associated 12 days after the intervention with lower mean cortisol levels (p = 0.02), greater weight gain and less need for parenteral nutrition in preterm infants, as well as less postpartum depression (p = 0.02) and lower cortisol levels (p = 0.002) in the mothers of preterm infants. Conclusions: This study suggests that KMC can be used to improve the stress of preterm infants and their mothers, and that the greater weight gain observed in these preterm infants could contribute to a shorter average hospital stay and lower healthcare expenditure.

Relationship Between Maternal COVID-19 Infection and In-Hospital Exclusive Breastfeeding for Term Newborns

Objective

To evaluate the relationship between maternal COVID-19 infection and the odds of in-hospital exclusive breastfeeding for term newborns.

Design

Retrospective descriptive quantitative.

Setting

A large, urban hospital with more than 6,000 births annually.

Sample

Term newborns born between March 1, 2020, and March 31, 2021 (N = 6,151).

Methods

We retrospectively extracted data from electronic health records to evaluate the relationship of maternal COVID-19 infection with the odds of in-hospital exclusive breastfeeding using univariate analysis and logistic regression models. The covariates included insurance type, race/ethnicity, glucose gel administration, length of stay, newborn gestational age, newborn birth weight, and maternal COVID-19 infection.

Results

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding (p = .138) after adjustment for covariates in the logistic regression model. However, when newborns who received pasteurized donor human milk supplementation were excluded from the logistic regression model, maternal COVID-19 infection significantly decreased the odds of in-hospital exclusive breastfeeding (p = .043).

Conclusion

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding when newborns received donor human milk supplementation. Access to donor human milk for supplementation for term newborns may protect the odds of in-hospital exclusive breastfeeding.

Oxytocin, the panacea for long-COVID? a review

Objectives

In this hypothesis paper we explore the underlying mechanisms for long-COVID and how the oxytocinergic neurones could be infected by SARS-CoV-2 leading to a reduction in plasma oxytocin (OXT). Furthermore, we aim to review the relevance of OXT and hypothalamic function in recovery from long-COVID symptoms and pathology, through exploring the pro-health effects of the OXT neuropeptide.

Methods

A review of published literature was surveyed using Google Scholar and PubMed.

Results

Numerous experimental data can be shown to correlate with OXT and long-COVID symptoms and conditions, thus providing strong circumstantial evidence to support our hypothesis. It is postulated that the reduction in plasma OXT due to acute and post-viral damage to the hypothalamus and oxytocinergic neurones contributes to the variable multi-system, remitting and relapsing nature of long-COVID. The intranasal route of OXT application was determined to be most appropriate and clinically relevant for the restoration of oxytocinergic function post COVID-19 infection.

Conclusions

We believe it is imperative to further investigate whether OXT alleviates the prolonged suffering of patients with long-COVID. Succinctly, OXT may be the much-needed post-pandemic panacea.

Ten Years of Neonatal Intensive Care Adaption to the Infants' Needs: Implementation of a Family-Centered Care Model with Single-Family Rooms in Norway

Ten years ago, the Neonatal intensive care unit in Drammen, Norway, implemented Single-Family Rooms (SFR), replacing the traditional open bay (OB) unit. Welcoming parents to stay together with their infant 24 h per day, seven days per week, was both challenging and inspiring. The aim of this paper is to describe the implementation of SFR and how they have contributed to a cultural change among the interprofessional staff. Parents want to participate in infant care, but to do so, they need information and supervision from nurses, as well as emotional support. Although SFR protect infants and provide private accommodation for parents, nurses may feel isolated and lack peer support. Our paper describes how we managed to systematically reorganize the nurse's workflow by using a Plan-Do-Study-Act (PDSA) cycle approach. Significant milestones are identified, and the implementation processes are displayed. The continuous parental presence has changed the way we perceive the family as a care recipient and how we involve the parents in daily care. We provide visions for the future with further developments of care adapted to infants' needs by providing neonatal intensive care with parents as equal partners.

Neurobiology of Parental Regulation of the Infant and Its Disruption by Trauma Within Attachment

The complex process of regulating physiological functions and homeostasis during external and internal disruptions develops slowly in altricial species, with parental care functioning as a co-regulator of infant physiological and emotional homeostasis. Here, we review our current understanding of the infant's use of parental behaviors for neurobehavioral regulation and its disruption with harsh parental care. Taking a cross-species view, we briefly review the human developmental literature that highlights the importance of the caregiver in scaffolding the child's physiological and emotional regulation, especially under threat and stress. We then use emerging corresponding animal literature within the phylogenetically preserved attachment system to help define neural systems supporting caregiver regulation and its supporting causal mechanism to provide translational bridges to inform causation and mechanisms impossible to define in children. Next, we briefly review animal research highlighting the impact of specific sensory stimuli imbedded in parental care as important for infant physiological and emotion regulation. We then highlight the importance of parental sensory stimuli gaining hedonic value to go beyond simple sensory stimuli to further impact neurobehavioral regulation, with poor quality of care compromising the infant's ability to use these cues for regulation. Clinically, parental regulation of the infant is correlated with later-life neurobehavioral outcome and quality of life. We suggest an understanding of this parental regulation of the infant's immediate neurobehavioral functioning within the context of attachment quality, that may provide insights into the complex processes during early life, initiating the pathway to pathology.

Long-Lasting Analgesia With Transdermal Fentanyl: A New Approach in Rat Neonatal Research

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.

Effects of Kangaroo Mother Care in the NICU on the Physiological Stress Parameters of Premature Infants: A Meta-Analysis of RCTs

OBJECTIVE

The aim of this study was to analyze the randomised controlled trials that explored the effect of kangaroo mother care on physiological stress parameters of premature infants.

METHODS

Two independent researchers performed a systematic review of indexed studies in PubMed, Embase, CINAHL, Cochrane and Scopus. We included data from randomized controlled trials measuring the effects of kangaroo care compared to standard incubator care on physiological stress outcomes, defined as oxygen saturation, body temperature, heart rate and respiratory rate. The PRISMA model was used to conduct data extraction. We performed a narrative synthesis of all studies and a meta-analysis when data were available from multiple studies that compared the same physiological parameters with the kangaroo method as an intervention and controls and used the same outcome measures.

RESULTS

Twelve studies were eligible for inclusion in this meta-analysis. According to statistical analysis, the mean respiratory rate of preterm infants receiving KMC was lower than that of infants receiving standard incubator care (MD, -3.50; 95% CI, -5.17 to -1.83; p < 0.00001). Infants who received kangaroo mother care had a higher mean heart rate, oxygen saturation and temperature, although these results were not statistically significant.

CONCLUSIONS

Current evidence suggests that kangaroo care in the neonatal intensive care unit setting is a safe method that may have a significant effect on some of the physiological parameters of stress in preterm infants. However, due to clinical heterogeneity, further studies are needed to assess the effects of physiological stress in the neonatal intensive care unit on the development of preterm infants.

Birth Experience, Postpartum PTSD and Depression before and during the Pandemic of COVID-19 in Russia

The aim of the study is to investigate the changes in the maternal healthcare system during the pandemic and their associations with maternal mental health in Russia. A sample of Russian women who gave birth during the first year of the COVID-19 pandemic (n = 1645) and matched controls, i.e., women who gave birth before the COVID-19 pandemic (n = 611), completed an anonymous Internet survey about recent childbirth. They were assessed for childbirth-related posttraumatic stress disorder (PTSD) and postpartum depression (PPD). Clinically relevant symptoms of PPD and PTSD were high before the pandemic and showed no significant change during the pandemic (p = 0.48 and p = 0.64, respectively). We found a notable increase in the frequency of obstetric violence (p = 0.015) during the pandemic, which, in turn, has a strong correlation with birth-related PTSD and PPD. The problem of ethical communication with patients among maternal healthcare professionals is acute in Russia, and it has been exacerbated by the pandemic. Family and doula support during labor can be a potential protective factor against obstetric violence.

Aging-Associated Differences in Epitranscriptomic m6A Regulation in Response to Acute Cardiac Ischemia/Reperfusion Injury in Female Mice

Elderly patients are more susceptible to ischemic injury. N6-methyladenosine (m6A) modification is the most abundant reversible epitranscriptomic modification in mammalian RNA and plays a vital role in many biological processes. However, it is unclear whether age difference impacts m6A RNA methylation in hearts and their response to acute myocardial ischemia/reperfusion (I/R) injury. In this study, we measured the global level of m6A RNA methylation as well as the expression of m6A RNA "writers" (methylation enzymes) and "erasers" (demethylation enzymes) in the hearts of young and elderly female mice undergone sham surgery or acute MI/R injury. We found that m6A RNA level and associate modifier gene expression was similar in intact young and old female hearts. However, young hearts show a significant reduction in m6A RNA while elderly hearts showed only a slight reduction in m6A RNA in response to acute I/R injury. To explore the mechanism of differential level of m6A RNA modification, we use qRT-PCR and Western blotting to compare the mRNA and protein expression of major m6A-related "writers" (Mettl3, Mettl14, and WTAP) and 'erasers" (ALKBH5 and FTO). Mettl3 mRNA and protein expression were significantly reduced in both young and elderly hearts. However, the levels of FTO's mRNA and protein were only significantly reduced in ischemic elderly hearts, and age-related downregulation of FTO may offset the effect of reduced Mettl3 on reduced m6A RNA level in the hearts of aging mice hearts with acute I/R injury, indicating aging-related differences in epitranscriptomic m6A regulation in hearts in response to acute I/R injury. To further investigate specific I/R related targets of Mettl3, we overexpressed Mettl3 in cardiomyocyte line (HL1) using lentiviral vector, and the m6A enrichment of Bcl2, Bax and PTEN were quantified with m6A RIP-qPCR, we found that m6A modification of PTEN mRNA decreased after in vitro hypoxia/reperfusion injury (iH/R) while Mettl3 augments m6A levels of both Bax and PTEN after iH/R, indicating that Bax and PTEN are target genes of Mettl3 under iH/R stress.
