New policies on skin-to-skin contact warrant an oxytocin-based perspective on perinatal health care.

Background: In 2023, the World Health Organization (WHO) published a Global Position Paper on Kangaroo Mother Care (KMC), which is applicable to all countries worldwide: from the moment of birth, every "small and sick" newborn should remain with mother in immediate and continuous skin-to-skin contact (SSC), receiving all required clinical care in that place. This was prompted by the startling results of a randomized controlled trial published in 2021: in which 1,609 infants receiving immediate SSC were compared with 1,602 controls that were separated from their mothers but otherwise received identical conventional state-of-the-art care. The intervention infants showed a 25% reduction in mortality after 28 days.

Immediate parent-infant skin-to-skin study (IPISTOSS): study protocol of a randomised controlled trial on very preterm infants cared for in skin-to-skin contact immediately after birth and potential physiological, epigenetic, psychological and neurodevelopmental consequences.

Introduction: In Scandinavia, 6% of infants are born preterm, before 37 gestational weeks. Instead of continuing in the in-utero environment, maturation needs to occur in a neonatal unit with support of vital functions, separated from the mother's warmth, nutrition and other benefits. Preterm infants face health and neurodevelopment challenges that may also affect the family and society at large.

Birth practices: Maternal-neonate separation as a source of toxic stress.

Maternal-neonate separation for human newborns has been the standard of care since the last century; low birth weight and preterm infants are still routinely separated from their mothers. With advanced technology, survival is good, but long-term developmental outcomes are very poor for these especially vulnerable newborns. The poor outcomes are similar to those described for adversity in childhood, ascribed to toxic stress.

Historical background to maternal-neonate separation and neonatal care.

Maternal-neonate separation after birth is standard practice in the modern obstetric care. This is however a relatively new phenomenon, and its origins are described. Around 1890, two obstetricians in France expanded on a newly invented egg hatchery as a method of caring for preterm newborns.

Nurturescience versus neuroscience: A case for rethinking perinatal mother-infant behaviors and relationship.

Behavioral and emotional outcomes for babies who experienced maternal separation due to prematurity or birth defects have not improved significantly for the last 20 years. Current theories and treatment paradigms based on neuroscience have not generated explanatory mechanisms that work, or provided testable hypotheses. This article proposes a new field of scientific investigation, "nurturescience" within which new hypotheses can be tested with novel instruments.

Hypothesis on supine sleep, sudden infant death syndrome reduction and association with increasing autism incidence.

Aim: To identify a hypothesis on: Supine sleep, sudden infant death syndrome (SIDS) reduction and association with increasing autism incidence.

Methods: Literature was searched for autism spectrum disorder incidence time trends, with correlation of change-points matching supine sleep campaigns. A mechanistic model expanding the hypothesis was constructed based on further review of epidemiological and other literature on autism.

Newly born low birthweight infants stabilise better in skin-to-skin contact than when separated from their mothers: a randomised controlled trial.

Aim: Routine care of low birthweight (LBW) neonates relies on incubators for stabilisation. An earlier study suggested that skin-to-skin contact achieves better physiological stability in the transition period when compared to incubator care. The aim of this study was to replicate that study with a larger sample.

The neuroscience of birth--and the case for Zero Separation.

Currently, Western maternal and neonatal care are to a large extent based on routine separation of mother and infant. It is argued that there is no scientific rationale for this practice and a body of new knowledge now exists that makes a case for Zero Separation of mother and newborn. For the infant, the promotion of Zero Separation is based on the need for maternal sensory inputs that regulate the physiology of the newborn.

Proposal for mechanisms of protection of supine sleep against sudden infant death syndrome: an integrated mechanism review.

Unlabelled: Supine sleep decreases sudden infant death syndrome (SIDS) incidence, however the mechanisms for this are unclear. The triple risk model for SIDS requires that one or more underlying abnormalities of breathing or autonomic control are present; these are rare, but brainstem defects are found in most SIDS cases. Supine sleep increases sympathetic nervous system tone, and level of state organization, and may therefore act as a stressor.

Neonatal stomach volume and physiology suggest feeding at 1-h intervals.

Unlabelled: There is insufficient evidence on optimal neonatal feeding intervals, with a wide range of practices. The stomach capacity could determine feeding frequency. A literature search was conducted for studies reporting volumes or dimensions of stomach capacity before or after birth.

Should neonates sleep alone?

Background: Maternal-neonate separation (MNS) in mammals is a model for studying the effects of stress on the development and function of physiological systems. In contrast, for humans, MNS is a Western norm and standard medical practice. However, the physiological impact of this is unknown.
