Necrotising enterocolitis (NEC) is a serious inflammatory bowel disease of prematurity with potentially devastating complications and remains a leading cause of morbidity and mortality among premature infants. In recent years, there has been accumulating data regarding benefits of using bowel ultrasound (BUS) in the diagnosis and management of NEC. Despite this, adoption of robust BUS programmes into clinical practice has been slow. As BUS is a relatively new technique, many barriers to implementation exist, namely lack of education and training for sonographers and radiologists, low case volume and unfamiliarity by clinicians regarding how to use the information provided. The aim of this manuscript is to provide a framework and a roadmap for units to implement BUS in day-to-day practice for NEC diagnosis and management.

Necrotising enterocolitis (NEC) is a leading cause of death and disability in preterm newborns. Early diagnosis through non-invasive investigations is a crucial strategy that can significantly improve outcomes. Hence, this review gives particular attention to the emerging role of abdominal ultrasound (AUS) in the early diagnosis of NEC, its performance against abdominal radiograph and the benefits of AUS use in daily practice. AUS has been used in the diagnosis and management of NEC for a couple of decades. However, its first-line use has been minimal, despite growing evidence demonstrating AUS can be a critical tool in the early diagnosis and management of NEC. In 2018, the NEC group of the International Neonatal Consortium recommended using AUS to detect pneumatosis and/or portal air in preterm NEC as part of the ‘Two out of three’ model. To facilitate widespread adoption, and future improvement in practice and outcomes, collaboration between neonatologists, surgeons and radiologists is needed to generate standard operating procedures and indications for use for AUS. The pace and scale of the benefit generated by use of AUS can be amplified through use of computer-aided detection and artificial intelligence.

The Family Initiative's International Neonatal Fathers Working Group, whose members are the authors of this paper, has reviewed the literature on engaging fathers in neonatal units, with the aim of making recommendations for improving experience of fathers as well as health outcomes in neonatal practice. We believe that supporting the father-baby bond and supporting co-parenting between the mother and the father benefits the health of the baby, for example, through improved weight gain and oxygen saturation and enhanced rates of breastfeeding. We find, however, that despite much interest in engaging with parents as full partners in the care of their baby, engaging fathers remains sub-optimal. Fathers typically describe the opportunity to bond with their babies, particularly skin-to-skin care, in glowing terms of gratitude, happiness and love. These sensations are underpinned by hormonal and neurobiological changes that take place in fathers when they care for their babies, as also happens with mothers. Fathers, however, are subject to different social expectations from mothers and this shapes how they respond to the situation and how neonatal staff treats them. Fathers are more likely to be considered responsible for earning, they are often considered to be less competent at caring than mothers and they are expected to be “the strong one”, providing support to mothers but not expecting it in return. Our review ends with 12 practical recommendations for neonatal teams to focus on: (1) assess the needs of mother and father individually, (2) consider individual needs and wants in family care plans, (3) ensure complete flexibility of access to the neonatal unit for fathers, (4) gear parenting education towards co-parenting, (5) actively promote father-baby bonding, (6) be attentive to fathers hiding their stress, (7) inform fathers directly not just via the mother, (8) facilitate peer-to-peer communication for fathers, (9) differentiate and analyse by gender in service evaluations, (10) train staff to work with fathers and to support co-parenting, (11) develop a father-friendly audit tool for neonatal units, and (12) organise an international consultation to update guidelines for neonatal care, including those of UNICEF.

An anonymous questionnaire study was conducted to explore the attitudes and current practices of neonatal clinical staff to fathers and Family Integrated Care (FICare) in 2 neonatal units (level 2 and level 3).

There is a growing understanding of the role and place of men in maternity care generally and for fathers of babies in neonatal care in particular. This review offers a systematic narrative review on issues affecting fathers, whose babies are admitted to neonatal units. Twenty-seven papers in the review highlighted four key themes: stress & anxiety; information; gender roles and emotions.

Chronic lung disease (CLD) is a major cause of long-term morbidity in extremely LBW infants with respiratory distress syndrome. Parenteral vitamin A administration decreases the risk of CLD. We tested the hypothesis that intratracheal vitamin A administration with surfactant is systemically bioavailable without interfering with the functional properties of exogenous surfactant. Newborn piglets were ventilated with 100% FiO2and sequential saline lavage induced respiratory distress syndrome. During lung injury induction, ventilator changes were allowed, but none were made following treatment allocation. Animals were assigned by chance in a blinded control trial to three groups: I = control; II = surfactant; III = surfactant + vitamin A. Hemodynamics, lung mechanics, and blood gases were measured following instrumentation, pre- and posttreatment for 4 h, at which time the liver was sampled for retinol determination. All parameters improved in animals receiving surfactant. A significant interaction existed between time and group for PaO2and alveolar-arterial oxygen difference (A-aDO2). Hepatic levels of retinol were higher (p < 0.001) in animals receiving retinyl acetate. Intratracheal administration of surfactant + vitamin A did not alter the beneficial effects of surfactant on lung compliance and gas exchange. Intratracheal Vitamin A was associated with rapid hepatic uptake. Further studies are warranted.

To determine whether photo-protecting total parenteral nutrition in preterm infants influences arterial blood pressure differently according to gender. Blood pressure is influenced by complex mechanisms of vasomodulation. Oxidants are mediators and effectors in such reactions. Shielding total parenteral nutrition from light contributes to decrease the generation of peroxides. Girls may be better protected against an oxidant load than boys. We questioned whether shielding total parenteral nutrition may have cardiovascular effects that are influenced by gender.

Failure to protect total parenteral nutrition (TPN) solutions from ambient light induces the generation of peroxides, which contributes to the oxidation of several amino acids. We hypothesized that photo-protection improves the metabolic response to TPN.

Failure to protect total parenteral nutrition (TPN) solutions from ambient light induces the generation of peroxides, which contributes to the oxidation of several amino acids. We hypothesized that photo-protection improves the metabolic response to TPN. To study the effects of photo-protecting TPN on urinary nitrogen and vitamin C excretion and to evaluate in premature infants the influence of sex. Premature infants were randomized to receive from birth light-exposed (LE) or light-protected (LP) TPN. Upon reaching full TPN, parenteral nutrient intakes were correlated with normalized urinary nitrogen and vitamin C concentrations. No differences were observed between LE and LP. However, sex-related differences were observed in nitrogen and vitamin C handling. In boys, 50% of the nitrogen loss was explained by parenteral amino acid intake, whereas in girls, no correlation was found. The inverse correlation observed between intake and urinary excretion only in girls suggests a state of greater vitamin C utilization in girls. These results demonstrate that sex-related differences in nitrogen/protein metabolism reported during enteral nutrition are seen during TPN as well. Sex is an important variable that will need to be taken into account in future studies evaluating the potential clinical effects of photo-protecting TPN.
