Purpose: The purpose of this study was to examine coregulation between mothers and preterm infants in hypothalamic-pituitary-adrenocortical (HPA) system activity, as indicated by salivary cortisol levels, while mothers held their infants. The research questions were (a) does mother—infant coregulation in HPA activity occur during holding? and (b) if mother— infant coregulation in HPA activity exists during holding, do type of holding, antenatal steroids, sound level, and maternal touch… 
Maternal sensitivity and infant and mother adrenocortical function across challenges
TLDR
It is found that maternal sensitivity was related to infant, but not maternal, cortisol levels and also to infant-mother cortisol attunement, and high cortisol response variability across challenges may simultaneously permit adaptation to threat and protect the infant from overexposure to corticosteroids.
Effect of holding on co-regulation in preterm infants: a randomized controlled trial.
TLDR
Investigating whether kangaroo holding of healthy preterm infants over the first eight weeks of an infant's life facilitates co-regulation of salivary cortisol suggests that holding promoted the expected decline in stress hormone levels.
The Stockholm Neonatal Family-Centered Care Study: effects on salivary cortisol in infants and their mothers.
TLDR
Family-centered care had no effect on salivary cortisol reactivity during diaper change, however, sharing the same environment may increase the concordance between preterm infants' and their mothers' salivARY cortisol levels.
Do infants show a cortisol awakening response?
TLDR
Both group-level and dyadic-level analyses showed that cortisol levels for mother-infant dyads were associated and cortisol levels did not significantly rise or fall following naps.
Increase in Oxytocin From Skin-to-Skin Contact Enhances Development of Parent–Infant Relationship
TLDR
Facilitation of SSC may be an effective intervention to reduce parent and infant stress in the NICU and advance the exploration of OT as a potential moderator for improving responsiveness and synchrony in parent–infant interactions.
The dual nature of hypothalamic-pituitary-adrenal axis regulation in dyads of very preterm infants and their mothers
TLDR
Findings suggest that multiple approaches to account for dyadic HPA axis co-regulation should be used in order to depict the complex pattern of biological rhythms coordination in mother-infant dyads.
Salivary and serum cortisol levels in newborn infants.
TLDR
The measurement of cortisol in saliva reflects serum cortisol levels in normal NBIs and shows a trend towards a spontaneous increase during the first month of life.
Parental oxytocin responses during skin-to-skin contact in pre-term infants.
TLDR
M-SSC and P- SSC activated the oxytocin release and reduced stress and anxiety responses in mothers and fathers of pre-term infants.
Stress Physiology in Infancy and Early Childhood: Cortisol Flexibility, Attunement and Coordination
TLDR
Measures of flexibility, attunement, and coordination in the context of multiple challenges to capture allostasis in environmental and physiological context are recommended.
The effect of a maternal history of childhood abuse on adrenocortical attunement in mothers and their toddlers
TLDR
In the context of a maternal HoA, it seems possible for mother-child-dyads to show less optimal interactional quality but be stronger attuned to each other biologically.

Effects of prenatal betamethasone exposure on regulation of stress physiology in healthy premature infants
TLDR
It is suggested that antenatal corticosteroids suppress infants' HPA response to a stressor typically encountered in a neonatal intensive care situation, as seen in infants born at 33-34 weeks gestation.
Effect of Gestational Age, Postnatal Age, and Illness on Plasma Cortisol Concentrations in Premature Infants
TLDR
It is concluded that plasma cortisol concentrations in the premature infant are significantly correlated with gestational age and to markers of illness.
Adrenocortical function in the very low birth weight infant: improved testing sensitivity and association with neonatal outcome.
TLDR
It is suggested that delayed maturation of adrenal response may result in physiologically inadequate cortisol concentrations in stressed very low birth weight infants and may contribute to the development of chronic lung disease.
Correlation between plasma and salivary cortisol levels in preterm infants.
TLDR
The adrenal response to ACTH can be detected in the saliva of premature newborns during the first week of life, and this response is correlated with plasma and salivary cortisol levels correlated at baseline and 1 hour after ACTH stimulation.
Maturity of the Adrenal Cortex in Very Preterm Infants Is Related to Gestational Age
TLDR
Levels of cortisone were higher in preterms born <30 wk, suggesting a lower activity of 11β-hydroxysteroid dehydrogenase that may be related to maturity as well.
Circulating glucocorticoid bioactivity in the preterm newborn after antenatal betamethasone treatment.
TLDR
Antenatal exposure of preterm fetuses to betamethasone causes a sizeable, but brief, peak of supraphysiological GBA, and approximately 3 d after the last betamETHasone dose, circulating GBA derives from cord cortisol concentration.
Cortisol production rates in preterm infants in relation to growth and illness: a noninvasive prospective study using gas chromatography-mass spectrometry.
TLDR
Severity of illness did not have a significant influence on CPRs in preterm infants, however, the highest CPRs were associated with a significantly higher incidence of cerebral bleeding, suggesting that pre term infants have the ability to regulate cortisol production.
Corticosteroid binding globulin, total serum cortisol, and stress in extremely low-birth-weight infants.
TLDR
It is indicated that CBG levels are lower in ELBW infants than in term infants, but low CBG Levels do not explain the low serum total cortisol levels found in some very sick infants.
The effects of repeat doses of antenatal corticosteroids on maternal adrenal function.
TLDR
Repeated courses of betamethasone lead to barely detectable maternal basal cortisol levels and secondary adrenal insufficiency and that repeated doses of maternal corticosteroids suppress the maternal hypothalamic-pituitary-adrenal axis.
Salivary cortisol in preterm infants: Validation of a simple method for collecting saliva for cortisol determination.
TLDR
The filter paper method is a valid method of saliva collection that is feasible to use with preterm infants and an inverse association was found between postconceptional age and one-minute APGAR scores and infant cortisol levels.
