ABSTRACT: Objective
To determine the effect of prophylactic dextrose gel for prevention of neonatal hypoglycaemia on neurodevelopment and executive function at 2 years' corrected age.Design
Prospective follow-up of a randomised trial.Setting
New Zealand.Patients
Participants from the pre-hypoglycaemia Prevention with Oral Dextrose (pre-hPOD) trial randomised to one of four dose regimes of buccal 40% dextrose gel or equivolume placebo.Main outcome measures
Coprimary outcomes were neurosensory impairment and executive function. Secondary outcomes were components of the primary outcomes, neurology, anthropometry and health measures.Results
We assessed 360 of 401 eligible children (90%) at 2 years' corrected age. There were no differences between dextrose gel dose groups, single or multiple dose groups, or any dextrose and any placebo groups in the risk of neurosensory impairment or low executive function (any dextrose vs any placebo neurosensory impairment: relative risk (RR) 0.77, 95% CI 0.50 to 1.19, p=0.23; low executive function: RR 0.50, 95% CI 0.24 to 1.06, p=0.07). There were also no differences between groups in any secondary outcomes. There was no difference between children who did or did not develop neonatal hypoglycaemia in the risk of neurosensory impairment (RR 1.05, 95% CI 0.68 to 1.64, p=0.81) or low executive function (RR 0.73, 95% CI 0.34 to 1.59, p=0.43).Conclusion
Prophylactic dextrose gel did not alter neurodevelopment or executive function and had no adverse effects to 2 years' corrected age, but this study was underpowered to detect potentially clinically important effects on neurosensory outcomes.

Project description:Newborn infants with risk factors may require intravenous (IV) dextrose for asymptomatic hypoglycemia. Administration of IV dextrose and transfer to the neonatal intensive care unit (NICU) may interfere with parent-infant bonding. To study the effect of implementing dextrose gel supplement with feeds in late preterm/term infants affected by asymptomatic hypoglycemia on reducing IV dextrose therapy. A retrospective study was conducted before and after dextrose gel use: 05/01/2014 to 10/31/2014 and 11/01/2014 to 04/30/2015, respectively. Asymptomatic hypoglycemic (blood glucose level <45 mg/dl) infants in the newborn nursery (NBN) were given a maximum of 3 doses of dextrose gel (200 mg/kg of 40% dextrose) along with feeds. Transfer to the NICU for IV dextrose was considered treatment failure. Dextrose gel with feeds increased the blood glucose level in 184/250 (74%) of asymptomatic hypoglycemic infants compared to 144/248 (58%) with feeds only (p < 0.01). Transfer from the NBN to the NICU for IV dextrose decreased from 35/1,000 to 25/1,000 live births (p < 0.01). Exclusive breastfeeding improved from 19 to 28% (p = 0.03). Use of dextrose gel with feeds reduced the need for IV fluids, avoided separation from the mother and promoted breastfeeding. Neonates who failed dextrose gel therapy were more likely to be large for gestational age, delivered by cesarean section and had lower baseline blood glucose levels.

Project description:BackgroundNeonatal hypoglycaemia is common, affecting up to 15% of newborns, and can cause brain damage. Currently, there are no strategies, beyond early feeding, to prevent neonatal hypoglycaemia. Our aim was to determine a dose of 40% oral dextrose gel that will prevent neonatal hypoglycaemia in newborn babies at risk.Methods and findingsWe conducted a randomised, double-blind, placebo-controlled dose-finding trial of buccal dextrose gel to prevent neonatal hypoglycaemia at two hospitals in New Zealand. Babies at risk of hypoglycaemia (infant of a mother with diabetes, late preterm delivery, small or large birthweight, or other risk factors) but without indication for admission to a neonatal intensive care unit (NICU) were randomly allocated either to one of four treatment groups: 40% dextrose at one of two doses (0.5 ml/kg = 200 mg/kg, or 1 ml/kg = 400 mg/kg), either once at 1 h of age or followed by three additional doses of dextrose (0.5 ml/kg before feeds in the first 12 h); or to one of four corresponding placebo groups. Treatments were administered by massaging gel into the buccal mucosa. The primary outcome was hypoglycaemia (<2.6 mM) in the first 48 h. Secondary outcomes included admission to a NICU, admission for hypoglycaemia, and breastfeeding at discharge and at 6 wk. Prespecified potential dose limitations were tolerance of gel, time taken to administer, messiness, and acceptability to parents. From August 2013 to November 2014, 416 babies were randomised. Compared to babies randomised to placebo, the risk of hypoglycaemia was lowest in babies randomised to a single dose of 200 mg/kg dextrose gel (relative risk [RR] 0.68; 95% confidence interval [CI] 0.47-0.99, p = 0.04) but was not significantly different between dose groups (p = 0.21). Compared to multiple doses, single doses of gel were better tolerated, quicker to administer, and less messy, but these limitations were not different between dextrose and placebo gel groups. Babies who received any dose of dextrose gel were less likely to develop hypoglycaemia than those who received placebo (RR 0.79; 95% CI 0.64-0.98, p = 0.03; number needed to treat = 10, 95% CI 5-115). Rates of NICU admission were similar (RR 0.64; 95% CI 0.33-1.25, p = 0.19), but admission for hypoglycaemia was less common in babies randomised to dextrose gel (RR 0.46; 95% CI 0.21-1.01, p = 0.05). Rates of breastfeeding were similar in both groups. Adverse effects were uncommon and not different between groups. A limitation of this study was that most of the babies in the trial were infants of mothers with diabetes (73%), which may reduce the applicability of the results to babies from other risk groups.ConclusionsThe incidence of neonatal hypoglycaemia can be reduced with a single dose of buccal 40% dextrose gel 200 mg/kg. A large randomised trial (Hypoglycaemia Prevention with Oral Dextrose [hPOD]) is under way to determine the effects on NICU admission and later outcomes.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12613000322730.

Project description:ObjectiveTo determine the effect of prophylactic dextrose gel on the infant gut microbiome.DesignObservational cohort study nested in a randomised trial.SettingThree maternity hospitals in New Zealand.PatientsInfants at risk of neonatal hypoglycaemia whose parents consented to participation in the hypoglycaemia Prevention in newborns with Oral Dextrose trial (hPOD). Infants were randomised to receive prophylactic dextrose gel or placebo gel, or were not randomised and received no gel (controls). Stool samples were collected on days 1, 7 and 28.Main outcome measuresThe primary outcome was microbiome beta-diversity at 4 weeks. Secondary outcomes were beta-diversity, alpha-diversity, bacterial DNA concentration, microbial community stability and relative abundance of individual bacterial taxa at each time point.ResultsWe analysed 434 stool samples from 165 infants using 16S rRNA gene amplicon sequencing. There were no differences between groups in beta-diversity at 4 weeks (p=0.49). There were also no differences between groups in any other microbiome measures including beta-diversity (p=0.53 at day 7), alpha-diversity (p=0.46 for day 7 and week 4), bacterial DNA concentration (p=0.91), microbial community stability (p=0.52) and microbial relative abundance at genus level. There was no evidence that exposure to any dextrose gel (prophylaxis or treatment) had any effect on the microbiome. Mode of birth, type of milk fed, hospital of birth and ethnicity were all associated with differences in the neonatal microbiome.ConclusionsClinicians and consumers can be reassured that dextrose gel used for prophylaxis or treatment of neonatal hypoglycaemia does not alter the neonatal gut microbiome.Trial registration number12614001263684.

Project description:BackgroundNeonatal hypoglycemia is common and can cause brain injury. Buccal dextrose gel is effective for treatment of neonatal hypoglycemia, and when used for prevention may reduce the incidence of hypoglycemia in babies at risk, but its clinical utility remains uncertain.Methods and findingsWe conducted a multicenter, double-blinded, placebo-controlled randomized trial in 18 New Zealand and Australian maternity hospitals from January 2015 to May 2019. Babies at risk of neonatal hypoglycemia (maternal diabetes, late preterm, or high or low birthweight) without indications for neonatal intensive care unit (NICU) admission were randomized to 0.5 ml/kg buccal 40% dextrose or placebo gel at 1 hour of age. Primary outcome was NICU admission, with power to detect a 4% absolute reduction. Secondary outcomes included hypoglycemia, NICU admission for hypoglycemia, hyperglycemia, breastfeeding at discharge, formula feeding at 6 weeks, and maternal satisfaction. Families and clinical and study staff were unaware of treatment allocation. A total of 2,149 babies were randomized (48.7% girls). NICU admission occurred for 111/1,070 (10.4%) randomized to dextrose gel and 100/1,063 (9.4%) randomized to placebo (adjusted relative risk [aRR] 1.10; 95% CI 0.86, 1.42; p = 0.44). Babies randomized to dextrose gel were less likely to become hypoglycemic (blood glucose < 2.6 mmol/l) (399/1,070, 37%, versus 448/1,063, 42%; aRR 0.88; 95% CI 0.80, 0.98; p = 0.02) although NICU admission for hypoglycemia was similar between groups (65/1,070, 6.1%, versus 48/1,063, 4.5%; aRR 1.35; 95% CI 0.94, 1.94; p = 0.10). There were no differences between groups in breastfeeding at discharge from hospital (aRR 1.00; 95% CI 0.99, 1.02; p = 0.67), receipt of formula before discharge (aRR 0.99; 95% CI 0.92, 1.08; p = 0.90), and formula feeding at 6 weeks (aRR 1.01; 95% CI 0.93, 1.10; p = 0.81), and there was no hyperglycemia. Most mothers (95%) would recommend the study to friends. No adverse effects, including 2 deaths in each group, were attributable to dextrose gel. Limitations of this study included that most participants (81%) were infants of mothers with diabetes, which may limit generalizability, and a less reliable analyzer was used in 16.5% of glucose measurements.ConclusionsIn this placebo-controlled randomized trial, prophylactic dextrose gel 200 mg/kg did not reduce NICU admission in babies at risk of hypoglycemia but did reduce hypoglycemia. Long-term follow-up is needed to determine the clinical utility of this strategy.Trial registrationACTRN 12614001263684.

Project description:Neonatal hypoglycaemia is associated with adverse development, particularly visual-motor and executive function impairment, in childhood. As neonatal hypoglycaemia is common and frequently asymptomatic in at-risk babies-ie, those born preterm, small or large for gestational age, or to mothers with diabetes, it is recommended that these babies are screened for hypoglycaemia in the first 1-2 days after birth with frequent blood glucose measurements. Neonatal hypoglycaemia can be prevented and treated with buccal dextrose gel, and it is also common to treat babies with hypoglycaemia with infant formula and intravenous dextrose. However, it is uncertain if screening, prophylaxis, or treatment improves long-term outcomes of babies at risk of neonatal hypoglycaemia. This narrative review assesses the latest evidence for screening, prophylaxis, and treatment of neonates at risk of hypoglycaemia to improve long-term neurodevelopmental outcomes.

Project description:ImportanceProphylactic oral dextrose gel reduces neonatal hypoglycemia, but later benefits or harms remain unclear.ObjectiveTo assess the effects on later development of prophylactic dextrose gel for infants born at risk of neonatal hypoglycemia.Design, setting, and participantsProspective follow-up of a multicenter randomized clinical trial conducted in 18 Australian and New Zealand hospitals from January 2015 to May 2019. Participants were late preterm or term at-risk infants; those randomized in 9 New Zealand centers (n = 1359) were included and followed up between January 2017 and July 2021.InterventionsInfants were randomized to prophylactic 40% dextrose (n = 681) or placebo (n = 678) gel, 0.5 mL/kg, massaged into the buccal mucosa 1 hour after birth.Main outcomes and measuresThe primary outcome of this follow-up study was neurosensory impairment at 2 years' corrected age. There were 44 secondary outcomes, including cognitive, language, and motor composite Bayley-III scores (mean [SD], 100 [15]; higher scores indicate better performance).ResultsOf eligible infants, 1197 (91%) were assessed (581 females [49%]). Neurosensory impairment was not significantly different between the dextrose and placebo gel groups (20.8% vs 18.7%; unadjusted risk difference [RD], 2.09% [95% CI, -2.43% to 6.60%]; adjusted risk ratio [aRR], 1.13 [95% CI, 0.90 to 1.41]). The risk of cognitive and language delay was not significantly different between the dextrose and placebo groups (cognitive: 7.6% vs 5.3%; RD, 2.32% [95% CI, -0.46% to 5.11%]; aRR, 1.40 [95% CI, 0.91 to 2.17]; language: 17.0% vs 14.7%; RD, 2.35% [95% CI, -1.80% to 6.50%]; aRR, 1.19 [95% CI, 0.92 to 1.54]). However, the dextrose gel group had a significantly higher risk of motor delay (2.5% vs 0.7%; RD, 1.81% [95% CI, 0.40% to 3.23%]; aRR, 3.79 [95% CI, 1.27 to 11.32]) and significantly lower composite scores for cognitive (adjusted mean difference [aMD], -1.30 [95% CI, -2.55 to -0.05]), language (aMD, -2.16 [95% CI, -3.86 to -0.46]), and motor (aMD, -1.40 [95% CI, -2.60 to -0.20]) performance. There were no significant differences between groups in the other 27 secondary outcomes.Conclusions and relevanceAmong late preterm and term infants born at risk of neonatal hypoglycemia, prophylactic oral 40% dextrose gel at 1 hour of age, compared with placebo, resulted in no significant difference in the risk of neurosensory impairment at 2 years' corrected age. However, the study may have been underpowered to detect a small but potentially clinically important increase in risk, and further research including longer-term follow-up is required.Trial registrationanzctr.org.au Identifier: ACTRN12614001263684.

Project description:BackgroundThere is a scarcity of information regarding the most important outcomes for research in neonatal units in low-resource settings. Identification of important outcomes by different stakeholder groups would inform the development of a core outcome set (COS) for use in neonatal research.ObjectiveTo determine the perceptions and opinions of parents of newborn babies regarding what outcomes were most important to them in order to contribute towards development of a COS for neonatal research in sub-Saharan Africa.MethodsSemistructured interviews were undertaken with parents, mostly mothers, of babies admitted to one neonatal unit in North central and one in Southwest Nigeria. Participants were purposively sampled to include parents of babies with common neonatal problems such as prematurity.ResultsWe conducted 31 interviews. The most frequently raised outcomes were breast feeding, good health outcomes for their baby, education, growth and financial cost. Parents placed more emphasis on quality of life and functional status than health complications.ConclusionsThe opinions of parents need to be considered in developing a COS for neonatal research in low-resource settings. Further research should assess the opinions of families in other low-resource settings and also engage a broader range of stakeholders.

Project description:BackgroundNeonatal hypoglycaemia is a common but treatable metabolic disorder that affects newborn infants and which, if not identified and treated adequately, may result in neurological sequelae that persist for the lifetime of the patient. The long-term financial and quality-of-life burden of neonatal hypoglycaemia has not been previously examined.MethodsWe assessed the postnatal hospital and long-term costs associated with neonatal hypoglycaemia over 80 year and 18 year time horizons, using a health-system perspective and assessing impact on quality of life using quality-adjusted life year (QALYs). A decision analytic model was used to represent key outcomes in the presence and absence of neonatal hypoglycaemia.ResultsThe chance of developing one of the outcomes of neonatal hypoglycaemia in our model (cerebral palsy, learning disabilities, seizures, vision disorders) was 24.03% in subjects who experienced neonatal hypoglycaemia and 3.56% in those who do did not. Over an 80 year time horizon a subject who experienced neonatal hypoglycaemia had a combined hospital and post-discharge cost of NZ$72,000 due to the outcomes modelled, which is NZ$66,000 greater than a subject without neonatal hypoglycaemia. The net monetary benefit lost due to neonatal hypoglycaemia, using a value per QALY of NZ$43,000, is NZ$180,000 over an 80 year time horizon.ConclusionsEven under the most conservative of estimates, neonatal hypoglycaemia contributes a significant financial burden to the health system both during childhood and over a lifetime. The combination of direct costs and loss of quality of life due to neonatal hypoglycaemia means that this condition warrants further research to focus on prevention and effective treatment.

Project description:Patent ductus arteriosus (PDA) is common among extremely preterm infants. In selected cases, surgical PDA ligation may be required. The timing for PDA ligation may depend upon a variety of factors, with potential clinical implications. We aimed to investigate the impact of different surgical PDA managements on ligation timing and neonatal outcomes. Inborn infants < 32 weeks of gestation and < 1500 g admitted at two tertiary Neonatal Intensive Care Units that underwent PDA ligation between 2007 and 2018 were enrolled in this retrospective cohort study and split into the following groups based on their surgical management: on-site bedside PDA ligation (ONS) vs. referral to an off-site pediatric cardiac surgery (OFS). Neonatal characteristics, surgical timing, and clinical outcomes of the enrolled infants were compared between the groups. Multivariate analysis was performed to evaluate the impact of PDA ligation timing on significantly different outcomes. Seventy-eight neonates (ONS, n = 39; OFS, n = 39) were included. Infants in the ONS group underwent PDA ligation significantly earlier than those in the OFS group (median age 12 vs. 36 days, p < 0.001) with no increase in postoperative mortality and complications. The multivariate analysis revealed a significant association between PDA ligation timing, late-onset sepsis prevalence (OR 1.045, 0.032), and oxygen need at discharge (OR 1.037, p = 0.025).Conclusions: Compared with off-site surgery, on-site bedside ligation allows an earlier surgical closure of PDA, with no apparent increase in mortality or complications. Earlier PDA ligation may contribute to reduced rates of late-onset sepsis and post-discharge home oxygen therapy, with possible cost-benefit implications. What is known: • Ineffective or contraindicated pharmacological closure of a hemodynamically significant PDA may require a surgical ligation. • Available literature comparing the effect of early vs. late PDA ligation on the main neonatal morbidities has yield contrasting results. What is new: • The availability of a cardiac surgery service performing bedside PDA ligation allows an earlier intervention compared to patient referral to an off-site center, with no difference in postoperative mortality and complications compared to off-site surgery. • Earlier PDA ligation was associated with a lower prevalence of late-onset sepsis and of oxygen need at discharge, with possible cost-benefit implications.
