Rapid exome sequencing: revolutionises the management of acutely unwell neonatesDiagnosing acutely unwell infants with a potential genetic diagnosis can be challenging for healthcare professionals. Evidence suggests that up to 13% of critically unwell infants on the neonatal intensive care unit (NICU) have an underlying molecular diagnosis and when identified directly affects treatment decisions in 83%. On 1st October 2019, the National Health Service England (NHSE) launched a nationally commissioned service so that rapid whole-exome sequencing can be offered to critically unwell babies and children with a likely monogenic disorder who are admitted to NICU and paediatric intensive care unit (PICU). We present 7 cases from two neonatal units in the West Midlands (UK), where rapid exome sequencing has revealed a genetic diagnosis. Early genetic diagnosis in this cohort has influenced management in all (100%) cases, and in 57% (4 in 7 cases), it has helped in the decision to reorientate care. In some cases, early diagnosis has reduced the need for invasive and unnecessary investigations and avoided the need for post-mortem investigations. The genetic diagnosis has helped in counselling the families regarding the recurrence risk for future pregnancies. In some cases, this has provided parents with the reassurance of a low recurrence. In others, it has resulted in the offer of prenatal diagnosis or assisted conception technologies. What is Known: • Rapid whole-exome sequencing was commissioned in the UK in October 2019. • It is available for critically unwell babies with a likely monogenic aetiology. What is New: • It helps management planning for rare genetic disorders and future pregnancies counselling. • It can reduce the need for invasive investigations and overall intensive care costs.

Neurodevelopmental outcomes following paracetamol use for treatment of patent ductus arteriosus: a review.Aim: Concerns exist regarding potential adverse neurodevelopmental outcomes associated with paracetamol exposure during pregnancy and early infancy. This review evaluates the evidence for the impact of paracetamol use for patent ductus arteriosus (PDA) treatment on neurodevelopmental outcomes in preterm infants. Methods: A literature search was performed via Medline, Ovid Embase and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. The search details are below: ('Infant, Newborn' [MeSH] OR 'neonate*' [Title/Abstract]) AND ('Paracetamol' [MeSH] OR 'Acetaminophen' [Title/Abstract]) AND ('Ductus Arteriosus, Patent/drug therapy' [MeSH] OR 'patent ductus arteriosus' [Title/Abstract]) AND ('Neurodevelopmental Disorders' [MeSH] OR 'neurodevelopment*' [Title/Abstract] OR 'Child Development' [MeSH] OR 'Developmental Disabilities' [MeSH]). All studies were critically appraised and synthesised. Results: Seven studies reported neurodevelopmental outcomes after paracetamol use for PDA treatment in preterm infants <32 weeks gestation. The studies varied in dosage, route, and duration of paracetamol administration and in the methods used to assess neurodevelopmental outcomes. None of the studies revealed different outcomes between paracetamol-exposed preterm infants and controls. Conclusion: Current low-to-moderate quality evidence suggests no association between paracetamol used for PDA treatment and adverse neurodevelopmental outcomes in preterm infants. Future well-powered studies with standardised neurodevelopmental assessments are warranted to strengthen the current evidence base.

Optimising frontline learning and engagement between consultant-led neonatal teams in the West Midlands: a survey on the utility of an augmented simulation training technique.Background: In England, neonatal care is delivered in operational delivery networks, comprising a combination of the Neonatal Intensive Care (NICU), Local-Neonatal (LNU) or Special-Care Units (SCU), based on their ability to care for babies with different degrees of illness or prematurity. With the development of network care pathways, the most premature and sickest are mostly triaged for delivery in services linked to NICU. This has created anxiety for teams in LNU and SCU. Less exposure to sicker babies has resulted in limited opportunities to maintain expertise for when these babies unexpectedly deliver at their centre and thereafter require transfer for care, to NICU. Simultaneously, LNU and SCU teams develop skills in the care of the less ill and premature baby which would also be of benefit to NICU teams. A need for mutual learning through inter-unit multidirectional collaborative learning and engagement (hereafter also called neonatal networking) between teams of different designations emerged. Here, neonatal networking is defined as collaboration, shared clinical learning and developing an understanding of local systems strengths and challenges between units of different and similar designations. We describe the responses to the development of a clinical and systems focussed platform for this engagement between different teams within our neonatal ODN. Method: An interactive 1-day programme was developed in the West Midlands, focussing on a non-hierarchical, equal partnership between neonatal teams from different unit designations. It utilised simulation around clinical scenarios, with a slant towards consultant engagement. Four groups rotating through four clinical simulation scenarios were developed. Each group participated in a clinical simulation scenario, led by a consultant and supported by nurses and doctors in training together with facilitators, with a further ~two consultants, as observers within the group. All were considered learners. Consultant candidates took turns to be participants and observers in the simulation scenarios so that at the end of the day all had led a scenario. Each simulation-clinical debrief session was lengthened by a further ~ 20 min, during which freestyle discussion with all learners occurred. This was to promote further bonding, through multidirectional sharing, and with a systems focus on understanding the strengths and challenges of practices in different units. A consultant focus was adopted to promote a long-term engagement between units around shared care. There were four time points for this neonatal networking during the course of the day. Qualitative assessment and a Likert scale were used to assess this initiative over 4 years. Results: One hundred fifty-five individuals involved in frontline neonatal care participated. Seventy-seven were consultants, supported by neonatal trainees, staff grade doctors, clinical fellows, advanced neonatal nurse practitioners and nurses in training. All were invited to participate in the survey. The survey response rate was 80.6%. Seventy-nine percent felt that this learning strategy was highly relevant; 96% agreed that for consultants this was appropriate adult learning. Ninety-eight percent agreed that consultant training encompassed more than bedside clinical management, including forging communication links between teams. Thematic responses suggested that this was a highly useful method for multi-directional learning around shared care between neonatal units. Conclusion: Simulation, enhanced with systems focussed debrief, appeared to be an acceptable method of promoting multidirectional learning within neonatal teams of differing designations within the WMNODN.

Breastfeeding promotes early neonatal regulatory T-cell expansion and immune tolerance of non-inherited maternal antigens.Background: Breastfeeding is associated with long-term health benefits, such as a lower incidence of childhood infections, asthma, obesity and autoimmune disorders. However, little is known regarding how the maternal and neonatal immune systems interact after parturition when the neonate receives nutrition from maternal breast milk. Methods: We undertook a comparative analysis of immune repertoire and function at birth and 3 weeks of age in a cohort of 38 term neonates born by caesarean section grouped according to feeding method (breast milk versus formula). We used flow cytometry to study the immune phenotype in neonatal and maternal blood samples and mixed lymphocyte reactions to establish the proliferation response of neonatal versus maternal lymphocytes and vice versa. The microbiome of neonatal stool samples was also investigated using 16S rRNA sequencing. Results: We show that the proportion of regulatory T cells (Tregs) increases in this period and is nearly twofold higher in exclusively breastfed neonates compared with those who received formula milk only. Moreover, breastfed neonates show a specific and Treg-dependent reduction in proliferative T-cell responses to non-inherited maternal antigens (NIMA), associated with a reduction in inflammatory cytokine production. We also observed the enrichment of short chain fatty acid producing taxa (Veillonella and Gemella) in stool samples of exclusively breastfed neonates. Conclusions: These data indicate that exposure of the neonate to maternal cells through breastfeeding acts to drive the maturation of Tregs and 'tolerizes' the neonate towards NIMA.

A case of an infant with hydrops fetalis and hypoxic-ischemic encephalopathy treated with therapeutic hypothermia.Hydrops fetalis (HF) is a serious fetal condition. Infants born with HF are often critically unwell, requiring resuscitation and prolonged intensive care admission. Despite medical advances, morbidity and mortality remain high. Therapeutic hypothermia is the standard of care for term and late preterm infants with moderate-to-severe hypoxic-ischemic encephalopathy (HIE), as it improves neurodevelopmental outcomes in surviving infants. To our knowledge, the use of therapeutic hypothermia has not previously been reported in infants with HF. We report the case of a term infant with undiagnosed HF, who required resuscitation and received 72 hours of therapeutic hypothermia for moderate HIE. We describe the cardiovascular instability encountered during therapeutic hypothermia and how it was successfully managed. She responded well to treatment and was discharged home bottle-feeding, with normal neurology and a normal brain magnetic resonance imaging scan. From this case, therapeutic hypothermia in infants with HF and HIE is feasible and can be beneficial in carefully selected HF infants meeting cooling criteria.

Neonatal BCG: a time for changeThe BCG vaccination programme in the UK is risk based and has usually been given to eligible babies soon after birth. On advice from the Joint Committee on Vaccination and Immunisation, NHS England and Improvement recently revised the timing of this vaccination to 28 days after birth or soon thereafter. In this article, we highlight the change in timing of vaccination, the rationale and barriers to BCG uptake that this change may pose.

Implementing less invasive surfactant administration on a neonatal unit.There is increasing evidence reflected in both UK 2019 NICE and European guidelines suggesting that less invasive surfactant administration (LISA) reduces the need for mechanical ventilation and reduces the combined outcome of death or bronchopulmonary dysplasia, and is now the optimal method for surfactant delivery in spontaneously breathing babies. Despite this, uptake in England has been slow compared with Europe. This quality improvement project outlines the process of implementing LISA in a neonatal intensive care unit over a 2-year period, the barriers and challenges which were encountered, and how they were overcome.
