Necrotizing enterocolitis (NEC) is a leading cause of morbidity and mortality in hospitalized infants. First classified through Bell staging in 1978, a number of additional definitions of NEC have been proposed in the subsequent decades. In this review, we summarize eight current definitions of NEC, and explore similarities and differences in clinical signs and radiographic features included within these definitions, as well as their limitations. We highlight the importance of a global consensus on defining NEC to improve NEC research and outcomes, incorporating input from participants at an international NEC conference. We also highlight the important role of patient-families in helping to redefine NEC.

BACKGROUND: Preterm formula milk (FM) is often prepared in advance, potentially affecting nutritional quality. Long-chain polyunsaturated fatty acids (LCPUFAs), important for brain and immune system function, are prone to lipid peroxidation, which correlates with comorbidities of prematurity. The effects of clinical storage practices on LCPUFA content and lipid peroxidation of preterm FM were investigated. METHODS: UK liquid and powder preterm FM (2017) (from two manufacturers) were subjected to routine storage conditions (liquid: refrigeration ≤10 h; powder: weekly preparation in accordance with the manufacturer's instructions and refrigeration ≤24 h for 4 weeks). LCPUFA content, thiobarbituric acid reactive substances and 4-hydroxy-2-nonenal (HNE) content were analysed. RESULTS: Storage did not significantly decrease LCPUFA content. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition recommended LCPUFA intake, whereas in utero accretion rates could not be achieved with both FM brands (liquid and powder). Lipid peroxidation was evident on opening, with 6× higher levels in powder. No effect of ≤10-h refrigeration on peroxidation was seen in liquid FM. In powder FM, it increased over refrigeration (HNE opening: 6.5-9.7 µg mL-1 versus day 28, 24 h: 16.6-36.5 µg mL-1 ) with a significant interaction between storage time and refrigeration (P = 0.015), with higher HNE at 4 h on days 0, 7, 14 and 21 (all P

ObjectiveTo describe temporal changes in inhaled nitric oxide (iNO) use in English neonatal units between 2010 and 2015.DesignRetrospective analysis using data extracted from the National Neonatal Research Database.SettingAll National Health Service neonatal units in England.PatientsInfants of all gestational ages born 2010–2015 admitted to a neonatal unit and received intensive care.Main outcome measuresProportion of infants who received iNO; age at initiation and duration of iNO use.Results4.9% (6346/129 883) of infants received iNO; 31% (1959/6346) were born 34 weeks of gestation. Between epoch 1 (2010–2011) and epoch 3 (2014–2015), there was (1) an increase in the proportion of infants receiving iNO: 34 weeks (4.5% vs 5.0%), (2) increase in postnatal age at iNO initiation: ConclusionsBetween 2010 and 2015, there was an increase in the use of iNO among infants admitted to English neonatal units. This was most notable among the most premature infants with an almost fourfold increase. Given the cost of iNO therapy, limited evidence of efficacy in preterm infants and potential for harm, we suggest that exposure to iNO should be limited, ideally to infants included in research studies (either observational or randomised placebo-controlled trial) or within a protocolised pathway. Development of consensus guidelines may also help standardise practice.

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.

Background: Donor human milk is increasingly used as alternative to mother’s own milk to feed preterm infants, however, it may provide less long-chain polyunsaturated fatty acid (LCPUFA), and more oxidised lipids, which may be detrimental for preterm infant health and development. Levels have not been reported for donor human milk in the U.K.\ud Methods: Donor human milk (n=19) from two neonatal units, milk from preterm mothers from a neonatal unit (n=10), and term mothers from the community (n=11) were analysed for fatty acid, malondialdehyde, 4-hydroxy-2-nonenal, and hexanal content. Study registration: NCT03573531\ud Results: Donor human milk had significantly lower absolute LCPUFA content compared to term milk (P

Summary Background Women across the world are mistreated during childbirth. We aimed to develop and implement evidence-informed, validated tools to measure mistreatment during childbirth, and report results from a cross-sectional study in four low-income and middle-income countries. Methods We prospectively recruited women aged at least 15 years in twelve health facilities (three per country) in Ghana, Guinea, Myanmar, and Nigeria between Sept 19, 2016, and Jan 18, 2018. Continuous observations of labour and childbirth were done from admission up to 2 h post partum. Surveys were administered by interviewers in the community to women up to 8 weeks post partum. Labour observations were not done in Myanmar. Data were collected on sociodemographics, obstetric history, and experiences of mistreatment. Findings 2016 labour observations and 2672 surveys were done. 838 (41·6%) of 2016 observed women and 945 (35·4%) of 2672 surveyed women experienced physical or verbal abuse, or stigma or discrimination. Physical and verbal abuse peaked 30 min before birth until 15 min after birth (observation). Many women did not consent for episiotomy (observation: 190 [75·1%] of 253; survey: 295 [56·1%] of 526) or caesarean section (observation: 35 [13·4%] of 261; survey: 52 [10·8%] of 483), despite receiving these procedures. 133 (5·0%) of 2672 women or their babies were detained in the facility because they were unable to pay the bill (survey). Younger age (15–19 years) and lack of education were the primary determinants of mistreatment (survey). For example, younger women with no education (odds ratio [OR] 3·6, 95% CI 1·6–8·0) and younger women with some education (OR 1·6, 1·1–2·3) were more likely to experience verbal abuse, compared with older women (≥30 years), adjusting for marital status and parity. Interpretation More than a third of women experienced mistreatment and were particularly vulnerable around the time of birth. Women who were younger and less educated were most at risk, suggesting inequalities in how women are treated during childbirth. Understanding drivers and structural dimensions of mistreatment, including gender and social inequalities, is essential to ensure that interventions adequately account for the broader context.

Donor human milk (DHM) is the recommended alternative, if maternal milk is unavailable. However, current human milk banking practices may negatively affect the nutritional quality of DHM. This review summarises the effects of these practices on polyunsaturated fatty acids, lipid mediators and antioxidants of human milk. Overall, there is considerable variation in the reported effects, and further research is needed, particularly with lipid mediators and antioxidants. However, to preserve nutritional quality, DHM should be protected from light exposure and storage at 4 °C minimised, to prevent decreases in vitamin C and endocannabinoids and increases in free fatty acids and lipid peroxidation products. Storage at -20 °C prior to pasteurisation should also be minimised, to prevent free fatty increases and total fat and endocannabinoid decreases. Storage ≤-70 °C is preferable wherever possible, although post-pasteurisation storage at -20 °C for three months appears safe for free fatty acids, lipid peroxidation products, and total fat content.

© 2018 IEEE. Despite 60 years of research into necrotising enterocolitis (NEC), our understanding of the disease has not improved enough to achieve better outcomes. Even though NEC has remained the leading cause of death and poor outcomes in preterm infants, there remain vital questions on how to define, differentiate and detect the condition. Numerous international groups have recently highlighted NEC as a research priority and called for broader engagement of the scientific community to move the field forward. The three foremost barriers at present are lack of suitable definition(s), lack of clean datasets and consequently a lack of scope to gain sufficient insights from data. This research paper proposes a new direction of travel to advance neonatal gastro-intestinal monitoring and strengthen our efforts to gain better insights from global databases. An integrated machine learning based model is recommended to produce a comprehensive disease model to manage the complexity of this multi-variate disease. This intelligent disease model would be used in the daily neonatal settings to help aggregate data to support clinical decision making, better capture the complexity of each patient to enrich global datasets to create bigger and better data. This paper reviews current machine learning and CAD technologies in neonatology and suggests an innovative approach for an NEC disease model.

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.

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.

The yardstick is even more stringent for scientific and medical advisers, who …

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% FiO2 and 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 PaO2 and alveolar-arterial oxygen difference (A-aDO2). Hepatic levels of retinol were higher (p

We report severe airway obstruction and distress at birth, in aterm newborn, caused by a congenital epiglottic cyst.Case reportA 3751 g female infant was born at 41 weeks to a 22-year-oldmother following an uneventful pregnancy. Antenatal ultrasoundscans at 18 and 22 weeks were reported normal. There wasevidence of respiratory distress and severe upper airway obstructionimmediately upon delivery. Direct laryngoscopy for intubationrevealed a white cystic mass in the oropharynx, obstructing thevisualization of the pharynx and, therefore, the glottis as well. Thepediatrician managed to move the mass out of the way, intubateorally and stabilize the airway. The infant was transferred to atertiary center for further management. Examination of the oralcavity revealed a white cystic mass filling the oropharynx.Transnasal fibro-optic laryngoscopy revealed the same but theexact site of origin could not be well delineated. Computedtomography (CT) was performed to rule out an intracranialconnection. The infant underwent surgery at 7 h of life.Examination of the oral cavity was undertaken in the operatingroom to try and establish exactly where the cyst attached andwhether it was broad based or on a stalk. This was difficult due tothe size of the cyst (Figure 1). The cyst was decompressed tofacilitate exposure and a revealed a viscous yellowish fluid. It wasestablished that the cyst was attached in a broad-based fashion tothe left lateral aspect of the epiglottis, into the vallecula, along thefree margin and lateral surface of the aryepiglottic fold and ontothe pharyngo-epiglottic fold.The covering of the cyst was then injected with 1% xylocainewith 1 in 200 000 epinephrine and deroofed. The sidewalls andbase of the cyst were dissected off of their respective underlyingstructures with microlaryngeal instruments utilizing high powermagnification of the microscope.The infant received broad-spectrum antibiotic coverage anddexamethasone in the perioperative period. Postoperative periodwas uneventful and the infant was successfully extubated after48 h. There was no evidence of upper airway obstruction or distresspostextubation and the infant was discharged home on day 4 oflife. At follow-up examination, 1 month postexcision, no evidenceof a recurrence was noted.Histological examination showed soft tissue lined by squamousepithelium, consistent with an epiglottic cyst.DiscussionCongenital laryngeal cysts are rare but may be fatal.
