Sex differences in newborn interaction with mother or father during skin-to-skin contact after Caesarean section

Maternal prenatal depressive symptoms and child brain responses to affective touch at two years of age

BACKGROUND

Touch is an essential form of mother-child interaction, instigating better social bonding and emotional stability.

METHODS

We used diffuse optical tomography to explore the relationship between total haemoglobin (HbT) responses to affective touch in the child's brain at two years of age and maternal self-reported prenatal depressive symptoms (EPDS). Affective touch was implemented via slow brushing of the child's right forearm at 3 cm/s and non-affective touch via fast brushing at 30 cm/s and HbT responses were recorded on the left hemisphere.

RESULTS

We discovered a cluster in the postcentral gyrus exhibiting a negative correlation (Pearson's r = -0.84, p = 0.015 corrected for multiple comparisons) between child HbT response to affective touch and EPDS at gestational week 34. Based on region of interest (ROI) analysis, we found negative correlations between child responses to affective touch and maternal prenatal EPDS at gestational week 14 in the precentral gyrus, Rolandic operculum and secondary somatosensory cortex. The responses to non-affective touch did not correlate with EPDS in these regions.

LIMITATIONS

The number of mother-child dyads was 16. However, by utilising high-density optode arrangements, individualised anatomical models, and video and accelerometry to monitor movement, we were able to minimize methodological sources of variability in the data.

CONCLUSIONS

The results show that maternal depressive symptoms during pregnancy may be associated with reduced child responses to affective touch in the temporoparietal cortex. Responses to affective touch may be considered as potential biomarkers for psychosocial development in children. Early identification of and intervention in maternal depression may be important already during early pregnancy.

The effect of early skin-to-skin contact after cesarean section on breastfeeding duration and development of atopic-allergic diseases

INTRODUCTION

Breastfeeding to strengthen the immune system suggests allergy prevention as a possible option. The connection between breastfeeding and the development of atopic-allergic diseases is being discussed. The primary aim of this work was to investigate an association of the first early skin-to-skin contact following cesarean section with the development of atopic diseases within the 1st year of life.

METHODS

The present study was conducted as a bicentric prospective cohort study in central Germany with a 15-month recruitment period. Data collection was by telephone interviews with a follow-up of 12 months. The statistical evaluation procedure was based on a hierarchical test of the association of early skin-to-skin contact between mother and child with the two main outcome measures. The primary outcome is the duration of breastfeeding. The second outcome is the onset of atopic-allergic disease within the 1st year of life.

RESULTS

Mothers breastfed longer if they had skin-to-skin contact within the first 30 minutes postpartum [χ²(df=5) = 19.020, p=0.002], if they breastfed their newborns early immediately after birth (p<0.001), and if the first skin-to-skin contact lasted more than one hour [χ²(df=4) = 19.617, p<0.001]. Regarding atopic-allergic diseases, no significant effects of skin-to-skin contact were found in relation to disease development. Regarding breastfeeding, no significant effects of atopic-allergic diseases could be detected either.

CONCLUSIONS

The results of this study reflect the benefits of skin-to-skin contact in the context of breastfeeding and atopic disease. The current scientific knowledge regarding skin contact and the development of atopic-allergic diseases should be extended and deepened.

Skin-to-Skin Care and Spontaneous Touch by Fathers in Full-Term Infants: A Systematic Review

A series of studies have shown that mothers' early tactile behaviors have positive effects, both on full-term and preterm infants, and on mothers alike. Regarding fathers, research has focused mostly on paternal skin-to-skin care with preterm infants and has overlooked the tactile behavior effects with full-term newborns on infants' outcomes and on fathers themselves. The current systematic review considered the evidence regarding paternal tactile behaviors with full-term infants, including skin-to-skin care (SSC) and spontaneous touch (ST), during parent-infant interactions, and differentiated biophysiological, behavioral and psychological variables both in fathers and in infants. We also compared fathers' and mothers' tactile behaviors for potential differences. The few available studies suggest that paternal touch-SSC and ST-can have positive effects on fathers and infants alike. They also show that, despite some intrinsic differences, paternal touch is as pleasant as maternal touch. However, given the paucity of studies on the topic, we discuss why this field of research should be further explored.

Effectiveness of early essential newborn care on breastfeeding and maternal outcomes: a nonrandomized controlled study

Background

Breastfeeding and maternal health play crucial roles in improving newborn health, which is closely related to the development of families and society. Early essential newborn care, which emphasizes early exclusive breastfeeding and skin-to-skin contact, is recommended by the World Health Organization. This study aimed to explore the association of early essential newborn care with breastfeeding and maternal outcomes.

Methods

A nonrandomized controlled study was carried out from May 2020 to January 2021 in a tertiary hospital in Chengdu city, China. Pregnant women were recruited from the maternity ward before they gave birth. Early essential newborn care was performed for 91 mother-newborn pairs after birth in the intervention group, while routine birth care was performed for 91 mother-newborn pairs in the control group. Data on breastfeeding and maternal outcomes were collected pre-test and post-test and were recorded by trained data collectors and retrieved from hospital case record files.

Results

Compared with the control group, the intervention group had a higher incidence of early breastfeeding initiation, an earlier initiation and longer duration for the first breastfeeding, a higher incidence of successful first breastfeeding, more exclusive breastfeeding at hospital discharge, higher maternal breastfeeding self-efficacy, a shorter duration of the third stage of labour, lower postpartum blood loss, and lower scores of maternal pain and anxiety postpartum; the differences were statistically significant (p < 0.05).

Conclusion

The implementation of high-quality early essential newborn care can help mothers initiate early breastfeeding, improve exclusive breastfeeding rates at hospital discharge, enhance breastfeeding self-efficacy, promote the woman’s recovery from labour, and reduce maternal anxiety and pain in the postpartum period. High-quality early essential newborn care is recommended to policymakers and medical professionals to improve breastfeeding and maternal outcomes.

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.

Imaging affective and non-affective touch processing in two-year-old children

Touch is an important component of early parent-child interaction and plays a critical role in the socio-emotional development of children. However, there are limited studies on touch processing amongst children in the age range from one to three years. The present study used frequency-domain diffuse optical tomography (DOT) to investigate the processing of affective and non-affective touch over left frontotemporal brain areas contralateral to the stimulated forearm in two-year-old children. Affective touch was administered by a single stroke with a soft brush over the child's right dorsal forearm at 3 cm/s, while non-affective touch was provided by multiple brush strokes at 30 cm/s. We found that in the insula, the total haemoglobin (HbT) response to slow brushing was significantly greater than the response to fast brushing (slow > fast). Additionally, a region in the postcentral gyrus, Rolandic operculum and superior temporal gyrus exhibited greater response to fast brushing than slow brushing (fast > slow). These findings confirm that an adult-like pattern of haemodynamic responses to affective and non-affective touch can be recorded in two-year-old subjects using DOT. To improve the accuracy of modelling light transport in the two-year-old subjects, we used a published age-appropriate atlas and deformed it to match the exterior shape of each subject's head. We estimated the combined scalp and skull, and grey matter (GM) optical properties by fitting simulated data to calibrated and coupling error corrected phase and amplitude measurements. By utilizing a two-compartment cerebrospinal fluid (CSF) model, the accuracy of estimation of GM optical properties and the localization of activation in the insula was improved. The techniques presented in this paper can be used to study neural development of children at different ages and illustrate that the technology is well-tolerated by most two-year-old children and not excessively sensitive to subject movement. The study points the way towards exciting possibilities in functional imaging of deeper functional areas near sulci in small children.

The Effect of Paternal Skin-to-Skin Care: A Systematic Review and Meta-analysis of Randomized Control Trials

BACKGROUND

Research about skin-to-skin care (SSC) experiences in early period after birth has focused on mothers and infants.

PURPOSE

The purpose of this study was to determine the outcomes of paternal skin-to-skin care (P-SSC) in both fathers and infants.

METHODS

The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed/MEDLINE, Embase, CINAHL, PsycInfo, Airiti Library, and Google Scholar were searched for randomized controlled trials (RCTs) that reported outcomes of P-SSC in both fathers and infants. We calculated pooled mean differences (MDs) and 95% confidence intervals (CIs) using RevMan 5.3 for the meta-analysis [PROSPERO: CRD42018106790].

RESULTS

Seven RCTs including a total of 552 participants were eligible for inclusion. Compared to the maternal skin-to-skin care (M-SSC), fathers in the P-SSC exhibited no significant differences in salivary oxytocin levels (MD: -0.35 pg/mL; 95% CI: -0.75, 0.05), salivary cortisol levels (MD: 0.25 μg/dL; 95% CI: -0.82, 1.33), or anxiety scores (MD: -0.17; 95% CI: -0.57, 0.22) during the period of SSC. Similarly, there were no significant differences in the salivary cortisol levels (MD: -0.11 μg/dL; 95% CI: -0.05, 0.28) among preterm infants between the 2 groups. However, the crying time was less among full-term infants in the P-SSC group compared with infants in the incubator care or cot care groups.

IMPLICATIONS FOR PRACTICE AND RESEARCH

P-SSC had similar effects as M-SSC on stress-related outcomes during and after SSC among fathers and infants in the early stages after birth. We recommend that P-SSC be implemented in the early stages after birth. Further RCTs with a longitudinal design and large samples are needed to better understand the long-term effects of P-SSC on fathers and infants.

Establishing clinical governance model in primary health care: A systematic review

Clinical governance is a systematic approach to enhancing the quality of primary health care and ensuring high clinical standards, responsiveness to performance, and continuous improvement in service quality. The objective of the current study was to investigate the global experiences of clinical governance in primary health care. In the present systematic review, relevant articles from different countries were searched in various databases such as MD PubMed from Medline portal, Emerald Springer link, ProQuest, Cochrane, Scopus, Web of Science, and Consult until April 2019. The searched articles were checked through CASP and PRISMA checklists, and their results were extracted. Of the 17 selected studies, 16 belonged to developed countries, including England (13), Australia, Italy, and New Zealand, and one was from Turkey. The findings were divided into three general categories: (1) principles of effectiveness and risk management, (2) deployment requirements such as structural and organizational needs, resource and communication, and information management, and (3) barriers of clinical governance toward providing primary health care. it is recommended that a suitable framework or model be developed and designed adapted to the local culture and taking into account all effective dimensions for a proper establishment and implementation of clinical governance in primary health care.

Can intravenous oxytocin infusion counteract hyperinflammation in COVID-19 infected patients?

OBJECTIVES

Based on its well-documented anti-inflammatory and restorative properties we propose trials with the natural hormone oxytocin for treatment of hospitalised Covid-19 patients.

METHODS

We searched for, retrieved, and commented on specific literature regarding multiple functions of oxytocin with a special focus on its modulation of inflammatory, immune, and restorative functions.

RESULTS

Available data gathered in animals and humans support the anti-inflammatory properties of oxytocin. The multiple anti-inflammatory effects of oxytocin have been demonstrated in vitro and in vivo in various animal models and also in humans in response to intravenous infusion of oxytocin. Furthermore, oxytocin has been documented to activate several types of protective and restorative mechanisms and to exert positive effects on the immune system.

CONCLUSIONS

In addition, to being anti-inflammatory, it may be hypothesised, that oxytocin may be less suppressive on adaptive immune systems, as compared with glucocorticoids. Finally, by its restorative effects coupled with its anti-stress and healing properties, oxytocin may shorten the recovery period of the Covid-19 patients.

Newborn infants who received skin-to-skin contact with fathers after Caesarean sections showed stable physiological patterns

Aim

Separating infants and their parents after a Caesarean section is still the routine care worldwide. This study investigated three caregiving models on the wakefulness and physiological parameters of full‐term infants after an elective Caesarean section.

Methods

Newborn infants born in a Chilean public hospital in 2009‐12 were randomised to three groups: cot, fathers' arms or skin‐to‐skin contact with their father. They were assessed at 15‐minute intervals, from 45 to 120 minutes after the Caesarean section. Their physiological parameters were measured, and their wakefulness was assessed using the Neonatal Behavioural Assessment Scale.

Results

We studied 95 infant (53% girls) born at a mean gestational age of 38.9 ± 0.9 weeks. Heart rates were significantly higher in the skin‐to‐skin than cot or fathers' arms groups and showed greater stability over time. Wakefulness was initially higher in the skin‐to‐skin group, but there were no significant differences by the end of the observation. There were no differences between the groups in peripheral oxygen saturation. Skin‐to‐skin contact had no negative impact on the infants.

Conclusion

The skin‐to‐skin group showed some advantages over the cot and fathers' arms groups when it came to establishing stable physiological parameters and wakefulness. This approach should be supported during mother‐infant separation.

The Role of Affectionate Caregiver Touch in Early Neurodevelopment and Parent-Infant Interactional Synchrony

Though rarely included in studies of parent–infant interactions, affectionate touch plays a unique and vital role in infant development. Previous studies in human and rodent models have established that early and consistent affectionate touch from a caregiver confers wide-ranging and holistic benefits for infant psychosocial and neurophysiological development. We begin with an introduction to the neurophysiological pathways for the positive effects of touch. Then, we provide a brief review of how affectionate touch tunes the development of infant somatosensory, autonomic (stress regulation), and immune systems. Affective touch also plays a foundational role in the establishment of social affiliative bonds and early psychosocial behavior. These touch-related bonding effects are known to be mediated primarily by the oxytocin system, but touch also activates mesocorticolimbic dopamine and endogenous opioid systems which aid the development of social cognitive processes such as social learning and reward processing. We conclude by proposing a unique role for affectionate touch as an essential pathway to establishing and maintaining parent-infant interactional synchrony at behavioral and neural levels. The limitations of the current understanding of affectionate touch in infant development point to fruitful avenues for future research.

Are There Epigenetic Oxytocin-Mediated Effects on the Mother and Infant during Physiological Childbirth?

INTRODUCTION

Studies have shown that long-term positive behavioural and physiological changes are induced in connection with vaginal, physiological birth, and skin-to-skin contact after birth in mothers and babies. Some of these effects are consistent with the effect profile of oxytocin. This scoping review explores whether epigenetic changes of the oxytocin gene and of the oxytocin receptor gene (OTR) are involved in these effects.

METHODS

We searched Pubmed, Medline, BioMed Central, Cochrane Library, OVID, and Web of Science for evidence of epigenetic changes in connection with childbirth in humans, with a particular focus on the oxytocin system.

RESULTS

There were no published studies identified that were related to epigenetic changes of oxytocin and its receptor in connection with labour, birth, and skin-to-skin contact after birth in mothers and babies. However, some studies were identified that showed polymorphisms of the oxytocin receptor influenced the progress of labour. We also identified studies in which the level of global methylation was measured in vaginal birth and caesarean section, with conflicting results. Some studies identified differences in the level of methylation of single genes linked to various effects, for example, immune response, metabolism, and inflammation. In some of these cases, the level of methylation was associated with the duration of labour or mode of birth. We also identified some studies that demonstrated long-term effects of mode of birth and of skin-to-skin contact linked to changes in oxytocin function.

CONCLUSION

There were no studies identified that showed epigenetic changes of the oxytocin system in connection with physiological birth. The lack of evidence, so far, regarding epigenetic changes did not exclude future demonstrations of such effects, as there was a definite role of oxytocin in creating long-term effects during the perinatal period. Such studies may not have been performed. Alternatively, the oxytocin linked effects might be indirectly mediated via other receptors and signalling systems. We conclude that there is a significant lack of research examining long-term changes of oxytocin function and long-term oxytocin mediated adaptive effects induced during physiological birth and skin-to-skin contact after birth in mothers and their infants.

Father Committed to Early Parenting from the First Father-child Contact Experienced at Birth

Objective: To know how the phenomenon of active paternal upbringing is shown from the father-child contact experience during birth. Method: Analysis of secondary information from a qualitative study of a phenomenological nature. Transcripts of interviews and focus groups of all the fathers who participated in a father-child contact protocol for a doctoral thesis. Results: The study revealed the global structure of the phenomenon, whose central axis corresponds to “father who advances towards the integral connection with his child and is committed with parenting”, and its three comprehensive categories: expectations of being a father and actor in parenting; the experience of being a father at birth time; and the everyday of the upbringing. Conclusion: Prenatal preparation and skin-to-skin contact during birth mobilize the father towards commitment and involvement with the upbringing of his child from the beginning.

Synthesizing Views to Understand Sex Differences in Response to Early Life Adversity

Sex as a biological variable (SABV) is critical for understanding the broad range of physiological, neurobiological, and behavioral consequences of early life adversity(ELA). The study of the interaction of SABV and ELA ties into several current debates, including the importance of taking into account SABV in research, differing strategies employed by males and females in response to adversity, and the possible evolutionary and developmental mechanisms of altered development in response to adversity. This review highlights the importance of studying both sexes, of understanding sex differences (and similarities) in response to ELA, and provides a context for the debate surrounding whether the response to ELA may be an adaptive process.

Effects of Paternal Skin-to-Skin Contact in Newborns and Fathers After Cesarean Delivery

The objective of this study was to investigate the effects of paternal skin-to-skin contact (SSC) on newborns and fathers after cesarean delivery. In total, 108 neonates born via elective cesarean delivery and their fathers were recruited into this study. The neonates were randomly divided into 2 groups (n = 54 each). Newborns in the treatment group received SSC from their fathers shortly after cesarean delivery, whereas those from the control group received only routine care. The neonates' physical condition, breastfeeding rate, and the paternal psychological outcomes were compared between the 2 groups. The newborns in the treatment group had a more stable heart rate and forehead temperature, less duration of crying, and started feeding behavior earlier. The duration of breastfeeding after SSC in the treatment group was longer as well, with statistical significance, than the control group (P < .05). In addition, fathers in the treatment group had lower scores of anxiety and depression and better role attainment than those in the control group, with statistical significance (P < .05). The paternal SSC after cesarean delivery was beneficial for newborns by stabilizing newborns' physical conditions and increasing the breastfeeding rate. Meanwhile, it could significantly reduce anxiety and depression of fathers and facilitate their role attainment.

Effect of Kangaroo Mother Care on Successful Breastfeeding: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

BACKGROUND & AIMS

Evaluating the effect of Kangaroo Mother Care (KMC) on breastfeeding success shows conflicting results. Regarding the importance of breastfeeding and uncertainties about its effect, this study intended to conduct a systematic review and meta-analysis of randomised controlled trials on the effect of KMC on success of breastfeeding.

METHODS

In this systematic review and meta-analysis study, required data were collected by searching the following keywords: breastfeeding, Breast-Feeding, "skin-to-skin", "Kangaroo Mother Care", randomized clinical trial. The following databases were searched: Google Scholar, PubMed, EMBASE, Scopus, and Cochrane Central Register of Controlled Trials. Two authors independently extracted the data. To estimate the Breast-Feeding outcome variables, CMA2 software was used. The risk of bias of studies was assessed with the criteria developed in the Cochrane Handbook.

RESULTS

Twenty articles were included. In the KMC and CNC groups, 1,432 and 1,410 neonates were examined. Breastfeeding success rate was higher in the KMC group within different time slots, however this difference was not statistically significant (RR=1.11(95CI, 0.93-1.34) and RR=1.13(95%CI, 0.92-1.34) based on the time slot and birth weight, respectively). The inter-groups differences in the mean scores of Infant Breast-Feeding Assessment Tool (IBFAT) were statistically significant (P<0.05). Breastfeeding was initiated very sooner in the KMC group, suggesting a statistically significant inter-groups difference -0.72(95%CI, from -0.92 to -0.53) (P<0.05). Majority of the studies had a high risk of bias.

CONCLUSION

Findings indicated a superiority of KMC over CNC in terms of breastfeeding success. Assessment of the complications and costs of KMC implementation is recommended.

Early skin-to-skin contact between healthy late preterm infants and their parents: an observational cohort study

Background

Skin-to-skin contact (SSC) is an important factor to consider in the care of late preterm infants (born between 34 0/7 and 36 6/7 completed weeks of gestation). The literature suggests that SSC between preterm infants and their mothers facilitates breastfeeding. However, more studies are needed to explore potential dose-response effects between SSC and breastfeeding as well as studies that explicitly investigate SSC by fathers among late preterm infants. The aim was to investigate the duration of healthy late preterm infants’ SSC with the mother and father, respectively, during the first 48 h after birth and the associations with breastfeeding (exclusive/partial at discharged), clinical and demographic variables.

Methods

This was an observational cohort study in which parents to healthy late preterm infants, born between 34 5/7 and 36 6/7 completed weeks of gestation, recorded duration of SSC provided by mother and father, respectively. Demographic and clinical variables were retrieved from the medical records and were used as predictors. Multiple linear regression analysis was used to assess the association between the predictors and the outcome, SSC (hours), separately for mothers and fathers.

Results

The mean (standard deviation [SD]) time per day spent with SSC with mothers (n = 64) and fathers (n = 64), was 14.7 (5.6) and 4.4 (3.3) hours during the first day (24 h) after birth and 9.2 (7.1) and 3.1 (3.3) hours during the second day (24 h), respectively. Regarding SSC with mothers, no variable was significantly associated with SSC during the first day, while the mean (95% confidence interval [CI]) time of SSC during the second day was 6.9 (1.4–12.4) hours shorter for each additional kg of birthweight (p = 0.014). Concerning SSC with fathers, the mean (95% CI) time of SSC during the first day was 2.1 (0.4–3.7) hours longer for infants born at night (p = 0.015), 1.7 (0.1–3.2) hours longer for boys (p = 0.033), 3.2 (1.2–5.2) hours longer for infants born by caesarean section (p = 0.003), and 1.6 (0.1–3.1) hours longer for infants exclusively breastfed at discharge (p = 0.040). During the second day, the mean (95% CI) time of SSC with fathers was 3.0 (0.6–5.4) hours shorter for each additional kg of birthweight (p = 0.014), 2.0 (0.5–3.6) hours longer for infants born during night-time (p = 0.011), 2.9 (1.4–4.4) hours longer if the mother was primipara (p < 0.001), and 1.9 (0.3–3.5) hours shorter if supplementary artificial milk feeds were given. None of the other predictors, i.e., mother’s age, gestational age, or induction of labor were significantly associated with infants’ SSC with mothers or fathers during any of the first two days after birth.

Conclusion

Future studies are warranted that investigate duration of SSC between late preterm infants and their parents separately and the associations with breastfeeding and other variables of clinical importance.

Skin-to-Skin Contact in Cesarean Birth and Duration of Breastfeeding: A Cohort Study

Early skin-to-skin contact (SSC) after birth is a physiological practice that is internationally recommended and has well-documented importance for the baby and for the mother. This study aims to examine SSC with a cohort of mothers or fathers in the operating room after a Cesarean section (C-section) and its relationship with duration of breastfeeding. From January 1, 2012, to December 31, 2012, at the Castelli Hospital in Verbania, Italy, a Baby Friendly designated hospital, 252 consecutive women who had a C-section were enrolled in the study and followed for 6 months. The sample was later divided into three groups depending on the real outcomes in the operating room: SSC with the mother (57.5%), SSC with the father (17.5%), and no SSC (25%). Our study showed a statistical association between skin-to-skin contact with the mother and the exclusive breastfeeding rates on discharge. This effect is maintained and statistically significant at three and six months, as compared to the groups that had paternal SSC or no SSC. After a C-section, skin-to-skin contact with the mother can be an important practice for support, promotion, and duration of breastfeeding.

Risk factors for exclusive breastfeeding lasting less than two months-Identifying women in need of targeted breastfeeding support

BACKGROUND

Breastfeeding rates in Sweden are declining, and it is important to identify women at risk for early cessation of exclusive breastfeeding.

OBJECTIVE

The aim of this study was to investigate factors associated with exclusive breastfeeding lasting less than two months postpartum.

METHODS

A population-based longitudinal study was conducted at Uppsala University Hospital, Sweden. Six hundred and seventy-nine women were included in this sub-study. Questionnaires were sent at five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration as well as several other background variables. The main outcome measure was exclusive breastfeeding lasting less than two months postpartum. Multivariable logistic regression analysis was used in order to calculate adjusted Odds Ratios (AOR) and 95% Confidence Intervals (95% CI).

RESULTS

Seventy-seven percent of the women reported exclusive breastfeeding at two months postpartum. The following variables in the multivariate regression analysis were independently associated with exclusive breastfeeding lasting less than two months postpartum: being a first time mother (AOR 2.15, 95% CI 1.32-3.49), reporting emotional distress during pregnancy (AOR 2.21, 95% CI 1.35-3.62) and giving birth by cesarean section (AOR 2.63, 95% CI 1.34-5.17).

CONCLUSIONS

Factors associated with shorter exclusive breastfeeding duration were determined. Identification of women experiencing emotional distress during pregnancy, as well as scrutiny of caregiving routines on cesarean section need to be addressed, in order to give individual targeted breastfeeding support and promote longer breastfeeding duration.

Early skin-to-skin contact after cesarean section: A randomized clinical pilot study

Objective

Early bonding by skin-to-skin contact (SSC) has been demonstrated to be beneficial for mothers and newborns following vaginal delivery. The aim of this study was to investigate the impact of intraoperative bonding (early SSC) after cesarean section on neonatal adaptation, maternal pain and stress response.

Study design

This prospective, randomized-controlled pilot study was performed at a single academic tertiary hospital (Department of Obstetrics and Gynecology, Medical University of Graz, Austria) between September 2013 and January 2014. Women were randomly assigned to intraoperative (“early”) SCC (n = 17) versus postoperative (“late”) SCC (n = 18). Main variables investigated were neonatal transition (Apgar score, arterial oxygen saturation, heart rate and temperature), maternal pain perception and both maternal and neonatal stress response by measuring the stress biomarkers salivary free cortisol and salivary alpha amylase.

Results

There was no evidence for differences in parameters reflecting neonatal transition or stress response between the ‘Early SSC Group’ and the ‘Late SSC Group’. Maternal salivary cortisol and alpha-amylase levels as well as maternal wellbeing and pain did not differ between the groups. However, the rise of maternal salivary alpha-amylase directly after delivery was higher in the ‘Early SSC Group’ compared to the ‘Late SSC Group’ (p = 0.004).

Conclusions

This study did not reveal significant risks for the newborn in terms of neonatal transition when early SSC is applied in the operating room. Maternal condition and stress marker levels did not differ either, although the rise of maternal salivary alpha-amylase directly after delivery was higher in the ‘Early SSC Group’ compared to the ‘Late SSC Group’, which may indicate a stressor sign due to intensive activation of the sympathetic-adreno-medullary-system. This needs to be further evaluated in a larger prospective randomized trial.

Early skin-to-skin contact for mothers and their healthy newborn infants

BACKGROUND

Mother-infant separation post birth is common. In standard hospital care, newborn infants are held wrapped or dressed in their mother's arms, placed in open cribs or under radiant warmers. Skin-to-skin contact (SSC) begins ideally at birth and should last continually until the end of the first breastfeeding. SSC involves placing the dried, naked baby prone on the mother's bare chest, often covered with a warm blanket. According to mammalian neuroscience, the intimate contact inherent in this place (habitat) evokes neuro-behaviors ensuring fulfillment of basic biological needs. This time frame immediately post birth may represent a 'sensitive period' for programming future physiology and behavior.

OBJECTIVES

To assess the effects of immediate or early SSC for healthy newborn infants compared to standard contact on establishment and maintenance of breastfeeding and infant physiology.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (17 December 2015), made personal contact with trialists, consulted the bibliography on kangaroo mother care (KMC) maintained by Dr Susan Ludington, and reviewed reference lists of retrieved studies.

SELECTION CRITERIA

Randomized controlled trials that compared immediate or early SSC with usual hospital care.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Quality of the evidence was assessed using the GRADE approach.

MAIN RESULTS

We included 46 trials with 3850 women and their infants; 38 trials with 3472 women and infants contributed data to our analyses. Trials took place in 21 countries, and most recruited small samples (just 12 trials randomized more than 100 women). Eight trials included women who had SSC after cesarean birth. All infants recruited to trials were healthy, and the majority were full term. Six trials studied late preterm infants (greater than 35 weeks' gestation). No included trial met all criteria for good quality with respect to methodology and reporting; no trial was successfully blinded, and all analyses were imprecise due to small sample size. Many analyses had statistical heterogeneity due to considerable differences between SSC and standard care control groups. Results for womenSSC women were more likely than women with standard contact to be breastfeeding at one to four months post birth, though there was some uncertainty in this estimate due to risks of bias in included trials (average risk ratio (RR) 1.24, 95% confidence interval (CI) 1.07 to 1.43; participants = 887; studies = 14; I² = 41%; GRADE: moderate quality). SSC women also breast fed their infants longer, though data were limited (mean difference (MD) 64 days, 95% CI 37.96 to 89.50; participants = 264; studies = six; GRADE:low quality); this result was from a sensitivity analysis excluding one trial contributing all of the heterogeneity in the primary analysis. SSC women were probably more likely to exclusively breast feed from hospital discharge to one month post birth and from six weeks to six months post birth, though both analyses had substantial heterogeneity (from discharge average RR 1.30, 95% CI 1.12 to 1.49; participants = 711; studies = six; I² = 44%; GRADE: moderate quality; from six weeks average RR 1.50, 95% CI 1.18 to 1.90; participants = 640; studies = seven; I² = 62%; GRADE: moderate quality).Women in the SCC group had higher mean scores for breastfeeding effectiveness, with moderate heterogeneity (IBFAT (Infant Breastfeeding Assessment Tool) score MD 2.28, 95% CI 1.41 to 3.15; participants = 384; studies = four; I² = 41%). SSC infants were more likely to breast feed successfully during their first feed, with high heterogeneity (average RR 1.32, 95% CI 1.04 to 1.67; participants = 575; studies = five; I² = 85%). Results for infantsSSC infants had higher SCRIP (stability of the cardio-respiratory system) scores overall, suggesting better stabilization on three physiological parameters. However, there were few infants, and the clinical significance of the test was unclear because trialists reported averages of multiple time points (standardized mean difference (SMD) 1.24, 95% CI 0.76 to 1.72; participants = 81; studies = two; GRADE low quality). SSC infants had higher blood glucose levels (MD 10.49, 95% CI 8.39 to 12.59; participants = 144; studies = three; GRADE: low quality), but similar temperature to infants in standard care (MD 0.30 degree Celcius (°C) 95% CI 0.13 °C to 0.47 °C; participants = 558; studies = six; I² = 88%; GRADE: low quality). Women and infants after cesarean birthWomen practicing SSC after cesarean birth were probably more likely to breast feed one to four months post birth and to breast feed successfully (IBFAT score), but analyses were based on just two trials and few women. Evidence was insufficient to determine whether SSC could improve breastfeeding at other times after cesarean. Single trials contributed to infant respiratory rate, maternal pain and maternal state anxiety with no power to detect group differences. SubgroupsWe found no differences for any outcome when we compared times of initiation (immediate less than 10 minutes post birth versus early 10 minutes or more post birth) or lengths of contact time (60 minutes or less contact versus more than 60 minutes contact).

AUTHORS' CONCLUSIONS

Evidence supports the use of SSC to promote breastfeeding. Studies with larger sample sizes are necessary to confirm physiological benefit for infants during transition to extra-uterine life and to establish possible dose-response effects and optimal initiation time. Methodological quality of trials remains problematic, and small trials reporting different outcomes with different scales and limited data limit our confidence in the benefits of SSC for infants. Our review included only healthy infants, which limits the range of physiological parameters observed and makes their interpretation difficult.

Interventions for women who have a caesarean birth to increase uptake and duration of breastfeeding: A systematic review

Rates of breastfeeding uptake are lower after a caesarean birth than vaginal birth, despite caesarean rates increasing globally over the past 30 years, and many high-income countries reporting overall caesarean rates of above 25%. A number of factors are likely to be associated with women's infant feeding decisions following a caesarean birth such as limited postoperative mobility, postoperative pain, and ongoing management of medical complications that may have triggered the need for a caesarean birth. The aim of this systematic review was to evaluate evidence of interventions on the initiation and duration of any and exclusive breastfeeding among women who had a planned or unplanned caesarean birth. Seven studies, presenting quantitative and qualitative evidence, published in the English language from January 1994 to February 2016 were included. A limited number of interventions were identified relevant to women who had had a caesarean birth. These included immediate or early skin-to-skin contact, parent education, the provision of sidecar bassinets when rooming-in, and use of breast pumps. Only one study, an intervention that included parent education and targeted breastfeeding support, increased initiation and continuation of breastfeeding, but due to methodological limitations, findings should be considered with caution. There is a need to better understand the impact of caesarean birth on maternal physiological, psychological, and physical recovery, the physiology of lactation and breastfeeding and infant feeding behaviors if effective interventions are to be implemented.

Skin-to-skin contact by fathers and the impact on infant and paternal outcomes: an integrative review

OBJECTIVE

to summarise research evidence on the impact of father-infant skin-to-skin contact on infant and paternal outcomes.

DESIGN

an integrative literature review.

DATA SOURCES

PubMed, ScienceDirect, PsycINFO, and Cumulative Index to Nursing & Allied Health.

REVIEW METHODS

studies included were: (1) published in English between January 1995 to September 2015; (2) primary researches; and (3) focused on fathers providing skin-to-skin contact with their infants and its impact on infant and paternal outcomes. The Joanna Briggs Institute's Critical Appraisal Checklists were used to appraise the scientific rigour of the studies.

FINDINGS

twelve studies (10 quantitative and two qualitative) were included in this review. Father-infant skin-to-skin contact had positive impacts on infants' outcomes, including temperature and pain, bio-physiological markers, behavioural response, as well as paternal outcomes, which include parental role attainment, paternal interaction behaviour, and paternal stress and anxiety.

CONCLUSIONS

a father's involvement in providing skin-to-skin contact seems to be feasible and beneficial to both infants and fathers. However, there has been a scarcity of literature that exclusively examines fathers' involvement and perceptions related to skin-to-skin contact in the postpartum period. Future research should examine skin-to-skin contact by fathers and its associated benefits, as well as fathers' perceptions on father-infant SSC among varied populations.

IMPLICATIONS FOR PRACTICE

a father's involvement in providing skin-to-skin contact should be promoted during the postnatal period. Father-infant skin-to-skin contact is a valuable alternative, especially during the unavailability of mothers due to special circumstances, including medical emergencies and caesarean section.

Educational Intervention for an Evidence-Based Nursing Practice of Skin-to-Skin Contact at Birth

This article presents the development and evaluation of an educational intervention aiming at an evidence-based practice of skin-to-skin contact at birth among nurses of a maternity care unit. Based on the Iowa Model of Evidence-Based Practice to Promote Quality Care, four educational sessions were developed according to an active-learning pedagogy. Even if the nurses' practice did not fully meet the recommendations for skin-to-skin contact, a pre- and postintervention evaluation showed some positive results, such as a longer duration of skin-to-skin contact immediately after birth, delivery of some routine care directly on mothers' chest, and improved parent education. The educational intervention seems to have enacted some evidence-based nursing practice changes regarding skin-to-skin contact at birth.

Implementing Family-Centered Cesarean Birth

Cesarean birth is recognized as a physical and psychological stressor for many women. Maternity practices during cesarean birth should meet women's needs, while maintaining safety, to optimize the experience. Family-centered cesarean birth is a package of interventions that encourages a woman to participate in choosing interventions that would be helpful when undergoing a planned or unplanned cesarean birth. Included in family-centered cesarean birth is implementation of skin-to-skin care in the operating room for neonates who appear term and healthy. The process of attempting to implement family-centered cesarean birth at one academic center is presented, including steps for implementation, benefits, challenges, and areas for continued improvement and research. This article is part of a special series of articles that address midwifery innovations in clinical practice, education, interprofessional collaboration, health policy, and global health.

Self-soothing behaviors with particular reference to oxytocin release induced by non-noxious sensory stimulation

Oxytocin, a hypothalamic nonapeptide, is linked to increased levels of social interaction, well-being and anti-stress effects. The effects of oxytocin that is released by sensory stimulation during different kinds of interactive behaviors are often underestimated or even forgotten. In fact, many of the positive effects caused during interaction, such a wellbeing, stress reduction and even health promotion, are indeed linked to oxytocin released in response to activation of various types of sensory nerves. Oxytocin is released in response to activation of sensory nerves during labor, breastfeeding and sexual activity. In addition oxytocin is released in response to low intensity stimulation of the skin, e.g., in response to touch, stroking, warm temperature, etc. Consequently oxytocin is not only released during interaction between mothers and infants, but also during positive interaction between adults or between humans and animals. Finally oxytocin is also released in response to suckling and food intake. Oxytocin released in the brain in response to sensory stimulation as a consequence of these types of interactive behaviors, contributes to every day wellbeing and ability to handle stress. Food intake or sex may be used or even abused to achieve oxytocin-linked wellbeing and stress relief to compensate for lack of good relationships or when the levels of anxiety are high. The present review article will summarize the role played by oxytocin released by sensory (in particular somatosensory) stimulation, during various kinds of interactive behaviors. Also the fact that the anti-stress effects of oxytocin are particularly strong when oxytocin is released in response to “low intensity” stimulation of the skin will be highlighted.

Early maternal separation: a rodent model of depression and a prevailing human condition

The early life of most mammals is spent in close contact with the mother, and for the neonate, early maternal separation is a traumatic event that, depending on various conditions, may shape its behavioral and neurochemical phenotype in adulthood. Studies on rodents demonstrated that a very brief separation followed by increased maternal care may positively affect the development of the offspring but that prolonged separation causes significant amounts of stress. The consequences of this stress (particularly the hyperreactivity of the HPA (hypothalamic-pituitary-adrenal) axis are expressed in adulthood and persist for life. Maternal separation in rodents, particularly rats, was used as a model for various psychotic conditions, especially depression. The most popular separation procedure of a 3-h daily separation from the second to the 12th postpartum day yields a depression model of high construct and predictive validity. The results of studies on maternal separation in rats and monkeys prompt a discussion of the consequences of traditional procedures in the maternity wards of developed countries where attention is focused on the hygiene of the neonates and not on their psychological needs. This alternate focus results in a drastic limitation of mother-infant contact and prolonged periods of separation. It is tempting to speculate that differences in the course and severity of various mental disorders, which are usually less prevalent in underdeveloped countries than in developed countries (as noted by Kraepelin), may be related to different modes of infant care. Only recently has so-called kangaroo mother care (establishing mother-infant skin-to-skin contact immediately after birth) become popular in developed countries. In addition to its instant benefits for the neonates, this procedure may also be beneficial for the mental health of the offspring in adulthood.

Immediate or early skin-to-skin contact after a Caesarean section: a review of the literature

The World Health Organization and the United Nations International Children's Emergency Fund recommends that mothers and newborns have skin-to-skin contact immediately after a vaginal birth, and as soon as the mother is alert and responsive after a Caesarean section. Skin-to-skin contact can be defined as placing a naked infant onto the bare chest of the mother. Caesarean birth is known to reduce initiation of breastfeeding, increase the length of time before the first breastfeed, reduce the incidence of exclusive breastfeeding, significantly delay the onset of lactation and increase the likelihood of supplementation. The aim of this review is to evaluate evidence on the facilitation of immediate (within minutes) or early (within 1 h) skin-to-skin contact following Caesarean section for healthy mothers and their healthy term newborns, and identify facilitators, barriers and associated maternal and newborn outcomes. A range of electronic databases were searched for papers reporting research findings published in English between January 2003 and October 2013. Seven papers met the criteria. This review has provided some evidence that with appropriate collaboration skin-to-skin contact during Caesarean surgery can be implemented. Further evidence was provided, albeit limited, that immediate or early skin-to-skin contact after a Caesarean section may increase breastfeeding initiation, decrease time to the first breastfeed, reduce formula supplementation in hospital, increase bonding and maternal satisfaction, maintain the temperature of newborns and reduce newborn stress.

Medically complex pregnancies and early breastfeeding behaviors: a retrospective analysis

BACKGROUND

Breastfeeding is beneficial for women and infants, and medical contraindications are rare. Prenatal and labor-related complications may hinder breastfeeding, but supportive hospital practices may encourage women who intend to breastfeed. We measured the relationship between having a complex pregnancy (entering pregnancy with hypertension, diabetes, or obesity) and early infant feeding, accounting for breastfeeding intentions and supportive hospital practices.

METHODS

We performed a retrospective analysis of data from a nationally-representative survey of women who gave birth in 2011-2012 in a US hospital (N = 2400). We used logistic regression to examine the relationship between pregnancy complexity and breastfeeding. Self-reported prepregnancy diabetes or hypertension, gestational diabetes, or obesity indicated a complex pregnancy. The outcome was feeding status 1 week postpartum; any breastfeeding was evaluated among women intending to breastfeed (N = 1990), and exclusive breastfeeding among women who intended to exclusively breastfeed (N = 1418). We also tested whether breastfeeding intentions or supportive hospital practices mediated the relationship between pregnancy complexity and infant feeding status.

RESULTS

More than 33% of women had a complex pregnancy; these women had 30% lower odds of intending to breastfeed (AOR = 0.71; 95% CI, 0.52-0.98). Rates of intention to exclusively breastfeed were similar for women with and without complex pregnancies. Women who intended to breastfeed had similar rates of any breastfeeding 1 week postpartum regardless of pregnancy complexity, but complexity was associated with >30% lower odds of exclusive breastfeeding 1 week among women who intended to exclusively breastfeed (AOR = 0.68; 95% CI, 0.47-0.98). Supportive hospital practices were strongly associated with higher odds of any or exclusive breastfeeding 1 week postpartum (AOR = 4.03; 95% CI, 1.81-8.94; and AOR = 2.68; 95% CI, 1.70-4.23, respectively).

CONCLUSIONS

Improving clinical and hospital support for women with complex pregnancies may increase breastfeeding rates and the benefits of breastfeeding for women and infants.
