Greenbury SF, Angelini ED, Ougham K, Battersby C, Gale C, Uthaya S, Modi Net al., 2021, Birthweight and patterns of postnatal weight gain in very and extremely preterm babies in England and Wales, 2008-19: a cohort study, The Lancet Child & Adolescent Health, ISSN: 2352-4642

BACKGROUND: Intrauterine and postnatal weight are widely regarded as biomarkers of fetal and neonatal wellbeing, but optimal weight gain following preterm birth is unknown. We aimed to describe changes over time in birthweight and postnatal weight gain in very and extremely preterm babies, in relation to major morbidity and healthy survival. METHODS: In this cohort study, we used whole-population data from the UK National Neonatal Research Database for infants below 32 weeks gestation admitted to neonatal units in England and Wales between Jan 1, 2008, and Dec 31, 2019. We used non-linear Gaussian process to estimate monthly trends, and Bayesian multilevel regression to estimate unadjusted and adjusted coefficients. We evaluated birthweight; weight change from birth to 14 days; weight at 36 weeks postmenstrual age; associated Z scores; and longitudinal weights for babies surviving to 36 weeks postmenstrual age with and without major morbidities. We adjusted birthweight for antenatal, perinatal, and demographic variables. We additionally adjusted change in weight at 14 days and weight at 36 weeks postmenstrual age, and their Z scores, for postnatal variables. FINDINGS: The cohort comprised 90 817 infants. Over the 12-year period, mean differences adjusted for antenatal, perinatal, demographic, and postnatal variables were 0 g (95% compatibility interval -7 to 7) for birthweight (-0·01 [-0·05 to 0·03] for change in associated Z score); 39 g (26 to 51) for change in weight from birth to 14 days (0·14 [0·08 to 0·19] for change in associated Z score); and 105 g (81 to 128) for weight at 36 weeks postmenstrual age (0·27 [0·21 to 0·33] for change in associated Z score). Greater weight at 36 weeks postmenstrual age was robust to additional adjustment for enteral nutritional intake. In babies surviving without major morbidity, weight velocity in all gestational age groups stabilised at around 34 weeks post

AIM: This review examined how applicable national and regional clinical practice guidelines and recommendations for managing neonates born to mothers with COVID-19 mothers were to the evolving pandemic. METHODS: A systematic search and review identified 20 guidelines and recommendations that had been published by 25 May 2020. We analysed documents from 17 countries: Australia, Brazil, Canada, China, France, India, Italy, Japan, Saudi Arabia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, the UK and the USA. RESULTS: The documents were based on expert consensus with limited evidence and were of variable, low methodological rigour. Most did not provide recommendations for delivery methods or managing symptomatic infants. None provided recommendations for post-discharge assimilation of potentially-infected infants into the community. The majority encouraged keeping mothers and infants together, subject to infection control measures, but one-third recommended separation. Although breastfeeding or using breastmilk were widely encouraged, two countries specifically prohibited this. CONCLUSION: The guidelines and recommendations for managing infants affected by COVID-19 were of low, variable quality and may be unsustainable. It is important that transmission risks are not increased when new information is incorporated into clinical recommendations. Practice guidelines should emphasise the extent of uncertainty and clearly define gaps in the evidence.

Introduction Preterm babies are among the highest users of parenteral nutrition (PN) of any patient group, but there is wide variation in commencement, duration, and composition of PN and uncertainty around which groups will benefit from early introduction. Recent studies in critically unwell adults and children suggest that harms, specifically increased rates of nosocomial infection, outweigh the benefits of early administration of PN. In this study, we will describe early PN use in neonatal units in England, Wales and Scotland. We will also evaluate if this is associated with differences in important neonatal outcomes in neonates born between 30+0 and 32+6 weeks+days gestation.Methods and analysis We will use routinely collected data from all neonatal units in England, Wales and Scotland, available in the National Neonatal Research Database (NNRD). We will describe clinical practice in relation to any use of PN during the first 7 postnatal days among neonates admitted to neonatal care between 1 January 2012 and 31 December 2017. We will compare outcomes in neonates born between 30+0 and 32+6 weeks+days gestation who did or did not receive PN in the first week after birth using a propensity score-matched approach. The primary outcome will be survival to discharge home. Secondary outcomes will include components of the neonatal core outcome set: outcomes identified as important by former patients, parents, clinicians and researchers.Ethics and dissemination We have obtained UK National Research Ethics Committee approval for this study (Ref: 18/NI/0214). The results of this study will be presented at academic conferences; the UK charity Bliss will aid dissemination to former patients and parents.

Background: The optimal nutritional regimen for preterm infants, including those that develop necrotising enterocolitis (NEC), is unknown. Objective: The objective here was to evaluate body composition at term in infants following NEC, in comparison with healthy infants. The primary outcome measure was non-adipose tissue mass (non-ATM). Methods: We compared body composition assessed by magnetic resonance imaging at term in infants born <31 weeks of gestational age that participated in NEON, a trial comparing incremental versus immediate delivery of parenteral amino acids on non-ATM, and SMOF versus intralipid on intrahepatocellular lipid content. There were no differences in the primary outcomes. We compared infants that received surgery for NEC (NEC-surgical), infants with medically managed NEC (NEC-medical), and infants without NEC (reference). Results: A total of 133 infants were included (8 NEC-surgical; 15 NEC-medical; 110 reference). In comparison with the reference group, infants in the NEC-surgical and NEC-medical groups were significantly lighter [adjusted mean difference (95% CI) NEC-surgical: –630 g (–1,010, –210), p = 0.003; NEC-medical: –440 g (–760, –110), p = 0.009] and the total adipose tissue volume (ATV) was significantly lower [NEC-surgical: –360 cm3 (–516, –204), p < 0.001; NEC-medical: –127 cm3 (–251, –4); p = 0.043]. There were no significant differences in non-ATM [adjusted mean difference (95% CI) NEC-surgical: –46 g (–281, 189), p = 0.70; NEC-medical: –122 g (–308, 63), p = 0.20]. Conclusion: The lower weight at term in preterm infants following surgically and medically managed NEC, in comparison to preterm infants that did not develop the disease, was secondary to a reduction in ATV. This suggests that the nutritional regimen received was adequate to preserve non-ATM but not to support the normal third-trimester deposition of adipose tissue

Fetal and Neonatal Edition, Vol: 103, Pages: F301-F306, ISSN: 1359-2998

In 2015, the Department of Health in England announced an ambition to reduce 'brain injuries occurring during or soon after birth'. We describe the development of a pragmatic case definition and present annual incidence rates.Retrospective cohort study using data held in the National Neonatal Research Database (NNRD) extracted from neonatal electronic patient records from all National Health Service (NHS) neonatal units in England, Wales and Scotland. In 2010-2011, population coverage in the NNRD was incomplete, hence rate estimates are presented as a range; from 2012, population coverage is complete, and rates (95% CIs) are presented. Rates are per 1000 live births.NHS neonatal units in England.Infants admitted for neonatal care; denominator: live births in England.'Brain injuries occurring at or soon after birth' defined as infants with seizures, hypoxic-ischaemic encephalopathy, stroke, intracranial haemorrhage, central nervous system infection and kernicterus and preterm infants with cystic periventricular leucomalacia.In 2010, the lower estimate of the rate of 'Brain injuries occurring at or soon after birth' in England was 4.53 and the upper estimate was 5.19; in 2015, the rate was 5.14 (4.97, 5.32). For preterm infants, the population incidence in 2015 was 25.88 (24.51, 27.33) and 3.47 (3.33, 3.62) for term infants. Hypoxic-ischaemic encephalopathy was the largest contributor to term brain injury, and intraventricular/periventricular haemorrhage was the largest contributor to preterm brain injury.Annual incidence rates for brain injuries can be estimated from data held in the NNRD; rates for individual conditions are consistent with published rates. Routinely recorded clinical data can be used for national surveillance, offering efficiencies over traditional approaches.

BackgroundParenteral nutrition is central to the care of very immature infants. Current international recommendations favour higher amino-acid intakes and fish oil-containing lipid emulsions. ObjectiveThe aim of this two-by-two factorial, double-blind multicentre randomised controlled trial was to compare the effect of high (immediate Recommended Daily Intake: Imm-RDI) versus low (incremental introduction: Inc-AA) parenteral amino-acid delivery, commenced within 24 hours of birth, on body composition, and a multi-component lipid emulsion containing 30% soy bean oil, 30% medium chain triglycerides, 25% olive oil and 15% fish oil (SMOF) versus soybean oil based lipid emulsion (SO) on Intra-Hepato-Cellular Lipid (IHCL) content. ResultsWe randomised 168 infants born <31 weeks gestation. We evaluated outcomes at term in 133 infants. There were no significant differences between Imm-RDI and Inc-AA groups for non-adipose mass (adjusted mean difference (95% CI): 1.0g (-108, 111) p=0.98) or between SMOF and SO groups for IHCL (adjusted mean ratio SMOF:SO (95% CI): 1.1 (0.8, 1.6) p=0.58). SMOF does not affect IHCL content. There was a significant interaction (p=0.05) between the two interventions for non-adipose mass. There were no significant interactions between group differences for either primary outcome measure after adjusting for additional confounders. Imm-RDI infants were more likely than Inc-AA infants to have blood urea nitrogen levels greater than 7mmol/l or 10mmol/l respectively (75% vs 49%; p<0.01 and 49% vs 18%; p<0.01). Head circumference at term was smaller in the Imm-RDI group (mean difference (95% CI): -0.8cm (-1.5, -0.1) p= 0.02). There were no significant differences in any pre-specified secondary outcomes including adiposity, liver function tests, incidence of conjugated hyperbilirubinaemia, weight, length, mortality and brain volumes.

BackgroundParenteral nutrition (PN) is central to the care of very immature infants. Early intakes of higher amounts of amino acids and the use of lipid emulsions containing fish oils are recommended by current international recommendations.ObjectiveTo confirm the safety and demonstrate efficacy of the immediate introduction of the recommended daily intake of amino acids (Imm-RDI) and soya bean oil, medium-chain triglycerides, olive oil and fish oil lipid in PN to increase non-adipose (lean) body mass and decrease intrahepatocellular lipid (IHCL) content.DesignMulticentre, double-blind, 2 × 2 factorial and randomised controlled trial (RCT).SettingNeonatal units in London and south-east England, UK.ParticipantsExtremely preterm infants born before 31 weeks of gestation without major congenital or life-threatening abnormalities who could to be randomised to receive PN within 24 hours of birth.InterventionsInfants were randomised within 24 hours of birth to receive PN containing either high [RDI of amino acids (Imm-RDI)] or low [incremental amino acids (Inc-AA) control] levels of amino acids. In addition, infants were randomised to receive either 20% SMOFlipid® (Fresenius Kabi AG, Richmond Hill, ON, Canada) or 20% Intralipid® (Fresenius Kabi AG, Richmond Hill, ON, Canada) (control). This resulted in four groups: (1) Inc-AA/Intralipid, (2) Inc-AA/SMOFlipid, (3) Imm-RDI/Intralipid and (4) Imm-RDI/SMOFlipid. The intervention was continued until infants were receiving 150 ml/kg/day of enteral feeds for 24 hours.Primary outcome measureFor the amino acid intervention, this was non-adipose or lean body mass measured by magnetic resonance imaging. For the lipid composition intervention, this was IHCL content as measured by hepatic magnetic resonance spectroscopy. Primary outcomes were measured at term age equivalent, between 37 and 44 weeks postmenstrual age.ResultsWe randomised 168 infants born before 31 weeks of gestation. We evaluated outc

Background: Optimal feeding regimens for infants ≤ 1000 g have not been established and are a global healthcare concern.Aims and objectives: A controlled trial to establish the safety and efficacy of high vs low volume initiation and rapid vs slow advancement of milk feeds in a resource-limited setting was undertaken.Methods: Infants ≤ 1000 g birthweight were randomised to one of four arms, either low (4 ml/kg/day) or high (24 ml/kg/day) initiation and either slow (24 ml/kg/day) or rapid (36 ml/kg/day) advancement of exclusive feeds of human milk (mother’s or donor) until a weight of 1200 g was reached. After this point, formula was used to supplement insufficient mother’s milk. The primary outcome was time to reach 1500 g.Results: infants were recruited (51: low/slow; 47: low/rapid; 52: high/slow; 50: high/rapid). Infants on rapid advancement regimens reached 1500 g most rapidly (hazard ratio 1.48, 95% CI 1.05–2.09, P=0.03). The rapid advancement groups also regained birthweight more rapidly (hazard ratio 1.77, 95% CI 1.26–2.50, P=0.001). There was no apparent effect of high vs low initiation volumes but there was some evidence of interaction between interventions. There were no significant differences in other secondary outcomes, including necrotising enterocolitis, feed intolerance and late-onset sepsis.Conclusions: In this small pilot study, higher initiation feed volumes and larger daily increments appeared to be well tolerated and resulted in more rapid early weight gain. These data provide justification for a larger study in resource-limited settings to address mortality, necrotising enterocolitis and other important outcomes.

Background: The effect of mode of infant feeding on adiposity deposition is not fully understood.Objective: The objective was to test the hypothesis that differences in total and regional adipose tissue content and intrahepatocellular lipid (IHCL) arise in early infancy between breast- and formula-fed infants and to describe longitudinal changes.Design: This prospective longitudinal cohort study was performed in 2 hospitals in the United Kingdom. Healthy, full-term, appropriate weight-for-gestational age infants were recruited; adipose tissue volume and distribution were directly quantified by using whole-body magnetic resonance imaging; IHCL was assessed by in vivo proton magnetic resonance spectroscopy. Measurements were performed after birth (median age: 13 d) and at 6–12 wk of age. Method of infant feeding was recorded prospectively by using maternally completed feeding diaries. Breastfed was defined as >80% of feeds consisting of breast milk at both points; formula-fed was defined as >80% of feeds consisting of formula milk at both points.Results: Longitudinal results were obtained from 70 infants (36 breastfed, 9 mixed-fed, and 25 formula-fed). No differences were found in total or regional adipose tissue or IHCL between breastfed and formula-fed infants. In pooled analyses including all feeding groups, IHCL and total adipose tissue approximately doubled between birth and 6–12 wk: IHCL after birth (median: 0.949; IQR: 0.521–1.711) and at 6–12 wk (1.828; 1.376–2.697; P < 0.001) and total adipose tissue after birth (0.749 L; 0.620–0.928 L) and at 6–12 wk (1.547 L; 1.332–1.790 L; P < 0.001). Increasing adiposity was characterized by greater relative increases in subcutaneous than in internal adipose tissue depots.Conclusions: No differences were detectable in adipose tissue or IHCL accretion between breastfed and formula-fed infants up to 2 mo. The substantial increase in IHCL seen over this period in bo

Other imaging techniques to quantify internal-abdominal adiposity (IA-AT) and subcutaneous-abdominal adiposity (SCA-AT) are frequently impractical in infants. The aim of this study was twofold: (a) to validate ultrasound (US) visceral and subcutaneous-abdominal depths in assessing IA-AT and SCA-AT from MRI as the reference method in infants and (b) to analyze the association between US abdominal adiposity and anthropometric measures at ages 3 months and 12 months. Twenty-two infants underwent MRI and US measures of abdominal adiposity. Abdominal US parameters and anthropometric variables were assessed in the Cambridge Baby Growth Study (CBGS), n = 487 infants (23 girls) at age 3 months and n = 495 infants (237 girls) at 12 months. US visceral and subcutaneous-abdominal depths correlated with MRI quantified IA-AT (r = 0.48, P < 0.05) and SCA-AT (r = 0.71, P < 0.001) volumes, respectively. In CBGS, mean US-visceral depths increased by ~20 % between ages 3 and 12 months (P < 0.0001) and at both ages were lower in infants breast-fed at 3 months than in other infants. US-visceral depths at both 3 and 12 months were inversely related to skinfold thickness at birth (P = 0.03 and P = 0.009 at 3 and 12 months, resp.; adjusted for current skinfold thickness). In contrast, US-subcutaneous-abdominal depth at 3 months was positively related to skinfold thickness at birth (P = 0.004). US measures can rank infants with higher or lower IA-AT and SCA-AT. Contrasting patterns of association with visceral and subcutaneous-abdominal adiposities indicate that they may be differentially regulated in infancy.
