Cerebral Synchronization Between Mothers and Their Newborns During Breastfeeding and Related Oxytocin Response, According to Different Reciprocal Positioning of the Dyad, and Possible Related Benefit for Postpartum Depressive Symptoms
Different reciprocal positions of mother and newborn during breastfeeding may be adopted. Other than the one derived from UNICEF guidelines, or standard position, an approach called biological nurturing has been recently proposed. It aims to promote the activation of neonatal primitive reflexes, breast problems reduction (e.g. cracked or sore nipple) and, overall, spontaneity and naturalness of mother-newborn dyad behaviour during feeding.
The study of newborn cortical activation by functional near-infrared spectroscopy (fNIRS), a safe and minimally invasive functional neuroimaging technique based on haemoglobin absorption of near-infrared light, showed that baby's cortex exhibit a wide activation associated with breastfeeding. Moreover, preliminary and not yet published data, collected by fNIRS hyperscanning (e.g. the simultaneous detection of brain functional activation from two individuals living the same experience) in the Nursery of our Institute, evidenced that mother-newborn dyads adopting a biological nurturing approach to breastfeeding show a neural synchronization between their frontal cortex during such experience. Basing on this new evidence, it is now worth to understand if a biological nurturing approach to breastfeeding may promote such neural synchronization, even when postpartum depressive symptoms are present. Accordingly, biological nurturing may result to be protective for the neural basis of mother-newborn relationship, also in case of a postnatal affective suffering and helping to prevent its potential long term consequences on maternal wellbeing and infant neurodevelopment as well. Moreover, since oxytocin is a neuropeptide with widespread influence on parental function, including lactation and nurturing maternal behaviour physiology, if a biological nurturing approach to breastfeeding may promote the oxytocin level in the mother and/or in the newborn is worth to understand as well, taking into account again possible relations with postpartum depression symptoms. the aim of this study is to evaluate, by fNIRS hyperscanning, if the frontal cerebral cortex functional synchronization of mother-newborn dyads, who adopt a reciprocal positioning according to the biological nurturing approach during breastfeeding, differs from that of mother-newborn dyads adopting the standard position, taking into account the intensity of mother's postpartum depressive symptoms.
2 Year Follow up of COSGOD III (COSGOD III-FU)- Ancillary Retrospective Observational Study to COSGOD III Trial
The COSGOD III trial performed follow up until term age or discharge from the neonatal intensive care unit, whatever came first. The first neonate was randomised in September 2017 and the last in October 2021. A prospective follow up of the included neonates until an age of two years was not feasible in the COSGOD III trial since funding for long-term follow-up was not available.
However, data on long-term outcome of the included neonates into COSGOD III trial are of high interest. In many centres, who participated in the COSGOD III trial neonates are assessed routinely for long term outcome in outpatient clinics with Bayleys III/IV test or PARCA-R (Parent Report of Children's Abilities) questionnaire.
Aim of the present study is therefore to analyse in neonates, who were included into the COSGOD III trial, in a retrospective observational study routinely performed long-term survival and neurodevelopmental outcome assessment at a corrected age of 2 years (18-30 months).
Activation of the Spinal Muscular Atrophy Neonatal Screening Program and Integration With Cystic Fibrosis Screening. Feasibility Study
Spinal muscular atrophy (SMA) is a group of disorders caused by the degeneration of the motor neuron cells of the anterior horn of the spinal cord and, in some subtypes, of the bulbar motor neurons. Almost all cases are genetically determined. Most SMAs are autosomal recessive diseases, caused by homozygous deletions of the survival motor neuron (SMN) gene located on the long arm of chromosome 5. The estimated incidence of recessive childhood and juvenile SMA linked to deletion of the SMN gene is 1 in 6000 to 10000 live births, with a carrier frequency of 1 in 35 in the general population, making it a major genetic cause of infant mortality. Up to 95-97% of all childhood cases are due to homozygous deletions of the survival motor neuron 1 (SMN1) gene, or telomeric SMN, located on chromosome 5q11.2-13.3. The remaining 3-5% of cases are due to small mutations in SMN1 (rather than complete deletions).
Until a few years ago, the prognosis of type 1 SMA was poor. In the absence of therapies, the only measures were supportive (ventilation, nutrition) and the prospect, especially in the early forms, was to accompany them towards an early end of life. There are currently three treatment options available: nusinersen, risdiplam, and gene therapy with onasemnogene abeparvovec. The three options were found to be equally effective in reducing the symptoms of the disease, making it possible to reach or safeguard fundamental stages in a child's neuromotor development, starting from the ability to remain seated. At this moment, gene therapy is probably the preferred choice. To date, in Italy, there are approximately 100 patients undergoing gene therapy.
To ensure maximum benefit for affected patients, it is essential that the therapy is administered as soon as possible. Literature shows how the administration of gene therapy in pre-symptomatic subjects made it possible to achieve a better neurological outcome compared to symptomatic patients. From this perspective, the inclusion of spinal muscular atrophy in neonatal screening is of fundamental relevance.
