[PMID: 38972961 DOI: 10.1038/s41390-024-03411-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 06/27/2024] [Accepted: 06/29/2024] [Indexed: 07/09/2024]
Abstract
Neonatal dysglycemia has been a longstanding interest of research in neonatology. Adverse outcomes from hypoglycemia were recognized early but are still being characterized. Premature infants additionally introduced and led the reflection on the importance of neonatal hyperglycemia. Cohorts of infants following neonatal encephalopathy provided further information about the impacts of hypoglycemia and, more recently, highlighted hyperglycemia as a central concern for this population. Innovative studies exposed the challenges of management of neonatal glycemic levels with a "u-shape" relationship between dysglycemia and adverse neurological outcomes. Lately, glycemic lability has been recognized as a key factor in adverse neurodevelopmental outcomes. Research and new technologies, such as MRI and continuous glucose monitoring, offered novel insight into neonatal dysglycemia. Combining clinical, physiological, and epidemiological data allowed the foundation of safe operational definitions, including initiation of treatment, to delineate neonatal hypoglycemia as ≤47 mg/dL, and >150-180 mg/dL for neonatal hyperglycemia. However, questions remain about the appropriate management of neonatal dysglycemia to optimize neurodevelopmental outcomes. Research collaborations and clinical trials with long-term follow-up and advanced use of evolving technologies will be necessary to continue to progress the fascinating world of neonatal dysglycemia and neurodevelopment outcomes. IMPACT STATEMENT: Safe operational definitions guide the initiation of treatment of neonatal hypoglycemia and hyperglycemia. Innovative studies exposed the challenges of neonatal glycemia management with a "u-shaped" relationship between dysglycemia and adverse neurological outcomes. The importance of glycemic lability is also being recognized. However, questions remain about the optimal management of neonatal dysglycemia to optimize neurodevelopmental outcomes. Research collaborations and clinical trials with long-term follow-up and advanced use of evolving technologies will be necessary to progress the fascinating world of neonatal dysglycemia and neurodevelopment outcomes.

Abstract
OBJECTIVE To characterize late preterm antenatal steroids (AS) use and associated neonatal outcomes in a single academic center. STUDY DESIGN Retrospective study of 503 singleton, mother-infant dyads delivered between 34 0/7 and 36 6/7 weeks gestation between January 1, 2016 and December 31, 2020. RESULTS Forty-three percent did not receive AS (No AS) prior to delivery. Among AS treated, 50% were sub-optimal dosing. No AS had higher preterm premature rupture of membranes and maternal diabetes. AS group had lower mean gestational age, birthweight, longer time from admission to delivery and longer NICU stay. There was no difference in neonatal hypoglycemia. CONCLUSIONS Sub-optimal AS dosing in late preterms remains high in our center. AS did not improve neonatal outcomes. Studies are needed to evaluate the impact of AS in diabetics delivering late preterm, to optimize the timing of AS dosing, and evaluate the longer term impact on late preterm infants.

Abstract
Neonatal hypoglycemia (NH) is broadly defined as a low plasma glucose concentration that elicits hypoglycemia-induced impaired brain function. To date, no universally accepted threshold (reference range) for plasma glucose levels in newborns has been published, as data consistently indicate that neurologic responses to hypoglycemia differ at various plasma glucose concentrations. Infants at risk for NH include infants of diabetic mothers, small or large for gestational age, and premature infants. Common manifestations include jitteriness, poor feeding, irritability, and encephalopathy. Neurodevelopmental morbidities associated with NH include cognitive and motor delays, cerebral palsy, vision and hearing impairment, and poor school performance. This article offers a timely discussion of the state of the science of NH and recommendations for neonatal providers focused on early identification and disease prevention.

Abstract
OBJECTIVE In recent years, a series of clinical guidelines on neonatal hypoglycemia have been developed in different countries and regions. This systematic review was aimed at providing evidence for clinical decision-making and providing ideas for future research by comparatively analyzing the contents of various guidelines. METHODS A multilateral approach was used, including comprehensive literature searches and online research. The retrieved studies were screened by two independent reviewers according to our inclusion criteria. The two reviewers independently extracted the descriptive data. Four appraisers assessed the guidelines using the AGREE-II instrument. RESULTS Ten clinical guidelines on neonatal hypoglycemia were included, with a mean score of 45.28%-83.45% in six domains. The guidelines are relatively consistent in their recommendations on clinical symptoms of neonatal hypoglycemia, but different in risk factors, preventive measures, thresholds for clinical management of hypoglycemia, target glucose ranges for its control, and pharmacotherapy. CONCLUSION By summarising the recommendations in the guidelines on neonatal hypoglycemia, we found that blood glucose values were not the only observational indicator, and other indicators (e.g., ketone bodies, lactate) related to glucose metabolism should also be considered for a comprehensive assessment. There is still a lack of consensus on thresholds for the clinical management of hypoglycemia and target glucose ranges for its control, and the recommendations on its pharmacotherapy are rather simple and sketchy. In the future, more high-quality studies are required to further improve the early identification of neonatal hypoglycemia and intervention strategies against it.

Abstract
AIMS In order to mitigate early hypoglycemia in preterm infants, some clinicians have recently explored interventions such as delivery room commencement of dextrose infusions or delivery room administration of buccal dextrose gel. This review aimed to systematically investigate the literature regarding the provision of delivery room (prior to admission) parenteral glucose as a method to reduce the risk of initial hypoglycemia (measured at the time of NICU admission blood testing) in preterm infants. MATERIALS AND METHODS Using PRISMA guidelines a literature search (May 2022) was conducted using PubMed, Embase, Scopus, Cochrane Library, OpenGrey, and Prospero databases. The clinicaltrials.gov database was searched for possible completed/ongoing clinical trials. Studies that included moderate preterm (≤33+6 weeks) or younger birth gestations or very low birth weight (or smaller) infants, and that administered parenteral glucose in the delivery room were included. The literature was appraised via data extraction, narrative synthesis, and critical review of the study data. RESULTS A total of five studies (published 2014-2022) were eligible for inclusion (three before-after "quasi-experimental" studies, one retrospective cohort study, and one case-control study). Most included studies used intravenous dextrose as the intervention. Individual study effects (odds ratios) favored the intervention in all included studies. It was felt that the low number of studies, the variability in study design, and the nonadjustment for confounding co-interventions (co-exposures) precluded a meta-analysis. Quality assessment of the studies revealed a spectrum of bias from low to high risk, however, most studies had moderate to high risk of bias, and their direction of bias favored the intervention. CONCLUSIONS This extensive search and systematic appraisal of the literature indicates that there exists few studies (these are low grade and at moderate to high risk of bias) for the interventions of either intravenous or buccal dextrose given in the delivery room. It is not clear if these interventions impact on rates of early (NICU admission) hypoglycemia in these preterm infants. Obtaining intravenous access in the delivery room is not guaranteed and can be difficult in these small infants. Future research should consider various routes for commencing delivery room glucose in these preterm infants and should take the form of randomized controlled trials.

Abstract
PURPOSE To determine incidence, timing and potential risk factors associated with hypoglycemia in the first day of life in very premature infants. METHODS Retrospective cohort study including all infants born before 32 weeks of gestation between 1 July 2017 and 31 December 2020 in the Erasmus MC Sophia Children's Hospital (Rotterdam, the Netherlands). Excluded were those who died within 24 h after birth or with no glucose data available. We collected maternal and neonatal characteristics from patient files, as well as all routine glucose values for the first 24 h. Hypoglycemia was defined as blood glucose value below 2.6 mmol/L. Risk factors were selected using univariable and multivariable logistic regression with stepwise backward elimination. Kaplan-Meier survival analysis was performed to examine time-to-event after birth. RESULTS Of 714 infants included (median gestational age 29.3 weeks, mean weight 1200 g), 137 (19%) had at least one episode of hypoglycemia, with a median time-to-event of 126 min [95%-CI 105-216]. Relevant independent risk factors for hypoglycemia included two maternal (insulin-dependent diabetes [OR 2.8; 95%-CI 1.3-6.1]; antenatal steroid administration [OR 1.7, 95%-CI 1.1-2.7]), and four neonatal factors (no IV-access in delivery room [OR 6.1, 95% CI-3.2-11.7], gestational age in weeks [OR 1.3, 95% CI-1.2-1.5], small-for-gestational-age [OR 2.6, 95%-CI 1.4-4.8], and no respiratory support (versus non-invasive support) [OR 2.3, 95%-CI 1.0-5.3]). CONCLUSION Six risk factors were identified for hypoglycemia in the first 24 h of life in very preterm infants, that can be used for development of prediction models, risk-based screening and updating guidelines.

Abstract
Maternal diabetes mellitus in pregnancy is associated with impairments in memory functions of the offspring in childhood and adolescence but has not been studied in adulthood. The association of perinatal hypoglycemia with memory has not been studied in adulthood either. The combined sequelae of these two risk factors have not been directly compared. We studied general cognitive ability and memory functions in a prospective follow-up of a cohort born in 1971 to 1974. The sample included participants exposed to prenatal hyperglycemia (n = 24), perinatal hypoglycemia (n = 19), or both (n = 7). It also included controls with no early risks (n = 82). We assessed the participants' Intelligence quotient (IQ), working memory, and immediate and delayed recall of both verbal and visual material at the age of 40. We did not find significant differences in IQ or the memory tests between the groups. We did identify an interaction (p = 0.03) of the early risk with the type of digit span task: compared to the controls, the participants exposed to perinatal hypoglycemia had a larger difference between the forward digit span, a measure of attention, and the backward digit span, a measure of working memory processing (p = 0.022). The interaction remained significant when birth weight was controlled for (p = 0.026). Thus, in this small cohort, prenatal hyperglycemia, perinatal hypoglycemia, and their combination appeared relatively benign disorders. The association of these conditions with neurocognitive impairments in adulthood remains unconfirmed. The significance of the working memory difference needs to be verified with a larger sample.

Abstract
IMPORTANCE Neonatal hypoglycemia is associated with increased risk of poor executive and visual-motor function, but implications for later learning are uncertain. OBJECTIVE To test the hypothesis that neonatal hypoglycemia is associated with educational performance at age 9 to 10 years. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of moderate to late preterm and term infants born at risk of hypoglycemia. Blood and masked interstitial sensor glucose concentrations were measured for up to 7 days. Infants with hypoglycemic episodes (blood glucose concentration <47 mg/dL [2.6 mmol/L]) were treated to maintain a blood glucose concentration of at least 47 mg/dL. Six hundred fourteen infants were recruited at Waikato Hospital, Hamilton, New Zealand, in 2006-2010; 480 were assessed at age 9 to 10 years in 2016-2020. EXPOSURES Hypoglycemia was defined as at least 1 hypoglycemic event, representing the sum of nonconcurrent hypoglycemic and interstitial episodes (sensor glucose concentration <47 mg/dL for ≥10 minutes) more than 20 minutes apart. MAIN OUTCOMES AND MEASURES The primary outcome was low educational achievement, defined as performing below or well below the normative curriculum level in standardized tests of reading comprehension or mathematics. There were 47 secondary outcomes related to executive function, visual-motor function, psychosocial adaptation, and general health. RESULTS Of 587 eligible children (230 [48%] female), 480 (82%) were assessed at a mean age of 9.4 (SD, 0.3) years. Children who were and were not exposed to neonatal hypoglycemia did not significantly differ on rates of low educational achievement (138/304 [47%] vs 82/176 [48%], respectively; adjusted risk difference, -2% [95% CI, -11% to 8%]; adjusted relative risk, 0.95 [95% CI, 0.78-1.15]). Children who were exposed to neonatal hypoglycemia, compared with those not exposed, were significantly less likely to be rated by teachers as being below or well below the curriculum level for reading (68/281 [24%] vs 49/157 [31%], respectively; adjusted risk difference, -9% [95% CI, -17% to -1%]; adjusted relative risk, 0.72 [95% CI, 0.53-0.99; P = .04]). Groups were not significantly different for other secondary end points. CONCLUSIONS AND RELEVANCE Among participants at risk of neonatal hypoglycemia who were screened and treated if needed, exposure to neonatal hypoglycemia compared with no such exposure was not significantly associated with lower educational achievement in mid-childhood.

Abstract
BACKGROUND Neonatal hypoglycaemia, a common condition, can be associated with brain injury. It is frequently managed by providing infants with an alternative source of glucose, often given enterally with milk-feeding or intravenously with dextrose solution, which may decrease breastfeeding success. Intravenous dextrose also often requires that mother and baby are cared for in separate environments. Oral dextrose gel is simple and inexpensive, and can be administered directly to the buccal mucosa for rapid correction of hypoglycaemia, in association with continued breastfeeding and maternal care. This is an update of a previous review published in 2016. OBJECTIVES To assess the effectiveness of oral dextrose gel in correcting hypoglycaemia in newborn infants from birth to discharge home and reducing long-term neurodevelopmental impairment. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase from database inception to October 2021. We also searched international clinical trials networks, the reference lists of included trials, and relevant systematic reviews identified in the search. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs comparing oral dextrose gel versus placebo, no treatment, or other therapies for the treatment of neonatal hypoglycaemia in newborn infants from birth to discharge home. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study quality and extracted data; they did not assess publications for which they were study authors. We contacted investigators to obtain additional information. We used fixed-effect models and the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included two studies conducted in high-income countries, involving 312 late preterm and at-risk term infants and comparing oral dextrose gel (40% concentration) to placebo gel. One study was at low risk of bias, and the other (an abstract) was at unclear to high risk of bias. Oral dextrose gel compared with placebo gel probably increases correction of hypoglycaemic events (rate ratio 1.08, 95% confidence interval (CI) 0.98 to 1.20; rate difference 66 more per 1000, 95% CI 17 fewer to 166 more; 1 study; 237 infants; moderate-certainty evidence), and may result in a slight reduction in the risk of major neurological disability at age two years or older, but the evidence is uncertain (risk ratio (RR) 0.46, 95% CI 0.09 to 2.47; risk difference (RD) 24 fewer per 1000, 95% CI 41 fewer to 66 more; 1 study, 185 children; low-certainty evidence). The evidence is very uncertain about the effect of oral dextrose gel compared with placebo gel or no gel on the need for intravenous treatment for hypoglycaemia (RR 0.78, 95% CI 0.46 to 1.32; RD 37 fewer per 1000, 95% CI 91 fewer to 54 more; 2 studies, 312 infants; very low-certainty evidence). Investigators in one study of 237 infants reported no adverse events (e.g. choking or vomiting at the time of administration) in the oral dextrose gel or placebo gel group (low-certainty evidence). Oral dextrose gel compared with placebo gel probably reduces the incidence of separation from the mother for treatment of hypoglycaemia (RR 0.54, 95% CI 0.31 to 0.93; RD 116 fewer per 1000, 95% CI 174 fewer to 18 fewer; 1 study, 237 infants; moderate-certainty evidence), and increases the likelihood of exclusive breastfeeding after discharge (RR 1.10, 95% CI 1.01 to 1.18; RD 87 more per 1000, 95% CI 9 more to 157 more; 1 study, 237 infants; moderate-certainty evidence). AUTHORS' CONCLUSIONS: Oral dextrose gel (specifically 40% dextrose concentration) used to treat hypoglycaemia in newborn infants (specifically at-risk late preterm and term infants) probably increases correction of hypoglycaemic events, and may result in a slight reduction in the risk of major neurological disability at age two years or older. Oral dextrose gel treatment probably reduces the incidence of separation from the mother for treatment and increases the likelihood of exclusive breastfeeding after discharge. No adverse events have been reported. Oral dextrose gel is probably an effective and safe first-line treatment for infants with neonatal hypoglycaemia in high-income settings. More evidence is needed about the effects of oral dextrose gel treatment on later neurological disability and the need for other treatments for hypoglycaemia. Future studies should be conducted in low-and middle-income settings, in extremely and moderately preterm infants, and compare oral dextrose gel with other therapies such as intravenous dextrose. There are two ongoing studies that may alter the conclusions of this review when published.

Abstract
INTRODUCTION Protocols to identify asymptomatic neonatal hypoglycemia (NH) rely on the presence of established risk factors (late preterm gestation, large or small for gestational age, and infant of a diabetic mother) for inclusion. We analyzed the performance of these risk factors in identifying hypoglycemia in modern practice, and additionally evaluated the optimal duration of screening blood glucose measurements. METHODS We analyzed a retrospective cohort of 830 infants with 1 or more known risk factor(s) for NH admitted to the mother-baby unit of a single tertiary-care center from May 2017 to April 2018. Manual chart review was performed for data extraction and confirmation of risk factor(s). Infants were excluded if glucose measurements were obtained for any reason other than screening for asymptomatic NH. RESULTS Of the 830 included infants, 31 (3.7%) ultimately received intravenous dextrose (IVD). Most screened infants (n = 510, 61.4%) did not develop hypoglycemia. None of the established risk factors showed strong association with hypoglycemia. Cesarean delivery was associated with hypoglycemia, although not strongly. All infants who received IVD for feeding-refractory hypoglycemia were identified by the first 2 measurements with nearly all (30/31, 97%) identified at the initial measurement. CONCLUSIONS Currently accepted risk factors are limited in their ability to identify infants who subsequently develop hypoglycemia, and as a result, most screened infants do not develop hypoglycemia. The majority of infants in our cohort who did develop hypoglycemia achieved normoglycemia with feeding-based interventions and did not require IVD. Those that received IVD were more likely to develop hypoglycemia early and to a more severe degree. Together, our data suggest further refinement of protocol duration and risk factors utilized for screening as potential areas of screening protocol optimization.

Abstract
BACKGROUND Neonatal hypoglycemia management in the first 48 hours is guided by the American Academy of Pediatrics (AAP) and Pediatric Endocrine Society (PES) recommendations. Our aim was to determine the incidence of hypoglycemia via point of care test (POCT) on the 2nd day of life (DOL) among healthy, asymptomatic neonates regardless of risk factors. METHODS In this prospective observational study, preprandial point of care glucose concentration was measured on the 2nd DOL in 150 healthy, asymptomatic neonates in the newborn nursery. We used 50 mg/dl (2.8 mmol/L) as the hypoglycemia threshold based on PES recommendations. RESULTS The incidence of hypoglycemia on the second DOL was 10% among asymptomatic neonates (no risk factors = 8% ; late preterm birth (LPT) + small for gestational age (SGA) = 16% ; large for gestational age (LGA) + infant of diabetic mother (IDM) = 6%). SGA + LPT neonates accounted for the majority of the hypoglycemic cases (53.3%) and exhibited a trend towards the lowest glucose concentration (p = 0.09). CONCLUSION The incidence of hypoglycemia on DOL 2 among asymptomatic neonates is high and of unclear significance in the absence of dedicated neurodevelopmental follow-up.

Abstract
BACKGROUND Blood glucose and serum sodium abnormalities in very low birth weight infants may cause increased morbidity and mortality, but data regarding the long-term outcomes are limited. This study aimed to investigate the association between the peak and nadir blood glucose and serum sodium levels and neurodevelopmental outcomes in very low birth weight infants. METHODS A single-center retrospective medical record of 284 infants with birth weight<1500 g born between February 1, 2011 and January 31, 2015 was reviewed. We analyzed the correlation between peak and nadir blood glucose and serum sodium levels during hospitalization and Bayley Scales of Infant and Toddler Development, third edition at 6, 12, and 24 months of corrected age. RESULTS A total of 284 very low birth weight premature infants were eligible, and 223, 208, and 188 patients were assessed at 6, 12, and 24 months of corrected age, respectively. Multiple linear regression analysis with generalized estimating equations showed that the BSID-III cognitive scores were significantly lower in the peak serum sodium group when sodium was ≧150 mmol/L (95% confidence interval -11.681 to -0.822) than when sodium did not exceed 150 mmol/L. CONCLUSION A peak serum sodium of ≧150 mmol/L is associated with poor cognitive outcomes in very low birth weight infants. Further studies are necessary to determine if this association is causal or an expression of disease severity.

Abstract
OBJECTIVE This study aimed to evaluate if early (within the first 3 hours after birth) transient neonatal hypoglycemia (TNH) is associated with poor academic performance in infants at-risk for hypoglycemia. STUDY DESIGN This was a retrospective cohort study of at risk-infants (late preterm infants, small and large for gestational age infants, and infants of diabetic mothers [IDMs]) who were born in 1998 and 1999 at the University of Arkansas for Medical Sciences and had ≥1 recorded glucose concentration. The outcome measure was proficiency on 4th grade literacy and mathematics achievement tests. Three glucose concentration cutoffs for defining hypoglycemia (<35, <40, and <45 mg/dL) were investigated. Logistic regression models were developed to examine the association between early TNH and achievement test proficiency based on perinatal factors. RESULTS Among 726 infants, 472 had one, 233 had two, and 21 had three risk factor(s). Early TNH (glucose concentration <35, <40, and <45 mg/dL) was observed in 6.3, 11.6, and 20.5% of the study cohort, respectively. Irrespective of the cutoff used, the frequency of early TNH (number of patients with early TNH in a risk category divided by the total number of patients in that category) was significantly greater among infants with multiple risk factors. After controlling for perinatal factors, early TNH (cutoffs <35 and <40 mg/dL) was significantly associated with decreased probability of proficiency in literacy but not mathematics. Despite that early TNH was more common in IDMs and infants with three risk factors, the category or number of risk factors did not impact academic proficiency. CONCLUSION Early TNH (<35 and <40 mg/dL) was associated with lower adjusted probability of proficiency on 4th grade literacy achievement tests in at-risk infants. The impact of early TNH on academic performance was similar irrespective of category or number of risk factors. KEY POINTS · Transient hypoglycemia was associated with lower proficiency on 4th grade tests in at-risk infants.. · The category of risk factors among at-risk infants did not impact 4th grade academic proficiency.. · The number of risk factors among at-risk infants did not impact 4th grade academic proficiency..

Abstract
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.

Abstract
Glucose supply and metabolism are essential for growth and normal brain development in both the fetus and newborn. Disorders of glucose availability and metabolism can result in either hypoglycemia or hyperglycemia. The first section of this manuscript will contrast recommendations from the American Academy of Pediatrics and the Pediatric Endocrine Society on the approach to defining neonatal hypoglycemia. Recent studies will be reviewed which add to the controversy. This review aims to discuss the evidence-based guidelines, definitions, pathogenesis, outcomes and management options in this field. The current variations in practices and possibilities of future trials are also addressed.

Abstract
OBJECTIVE To investigate the success rate of intramuscular (IM) glucagon in preventing need for IV glucose and describe its glycemic effect. METHODS Retrospective study of 158 consecutive term neonates with feeding-resistant hypoglycemia treated with glucagon. RESULTS After glucagon, blood glucose (BG) increased in all but 1 infant by 25.9 ± 17.1, 42.1 ± 21.1, and 39.2 ± 28.3 mg/dL (1.4 ± 0.9, 2.3 ± 1.2, 2.2 ± 1.6 mmol/L) at 30, 60 and 120 mins respectively. In multivariable logistic regression, glucagon success was dependent upon gender (increased male risk) (P = 0.021), meeting American Academy of Pediatrics (AAP) criteria for immediate IV glucose (P = 0.004), birth weight, (P = 0.018) and delta glucose concentration at 60 min (P = 0.013). After IM glucagon, 24 out of 49 infants that met AAP criteria for immediate IV glucose (49%) ended up not requiring any additional intervention. CONCLUSIONS Glucagon increases BG nearly universally in hypoglycemic infants and allowed reducing the number of infants that needed immediate IV glucose infusion therapy by ≈half.

Abstract
BACKGROUND Neonatal 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. METHODS We 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. RESULTS The 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. CONCLUSIONS Even 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.

Abstract
Neonatal hypoglycaemia is a common metabolic disorder presenting in the first days of life and one potentially preventable cause of brain injury. However, a universal approach to diagnosis and management is still lacking. The rapid decrease in blood glucose (BG) after birth triggers homeostatic mechanisms. Most episodes of hypoglycaemia are asymptomatic, and symptoms, when they occur, are nonspecific. Therefore, neonatologists are presented with the challenge of identifying infants at risk who might benefit from a rapid and effective therapy while sparing others unnecessary sampling and overtreatment. There is much controversy regarding the definition of hypoglycaemia, and one level does not fit all infants since postnatal age and clinical situations trigger different accepted thresholds for therapy. The concentration and duration of BG which cause neurological damage are unclear. Recognizing which newborn infants are at risk of hypoglycaemia and establishing protocols for treatment are essential to avoid possible deleterious effects on neurodevelopment. Early breastfeeding may reduce the risk of hypoglycaemia, but in some cases, the amount of breast milk available immediately after birth is insufficient or non-existent. In these situations, other therapeutic alternatives such as oral dextrose gel may lower the risk for NICU admissions. Current guidelines continue to be based on expert opinion and weak evidence. However, malpractice litigation related to neurodevelopmental disorders is frequent in children who suffered hypoglycaemia in the neonatal period even if they had other important factors contributing to the poor outcome. This review is aimed to help the practicing paediatricians and neonatologists to comprehend neonatal hypoglycaemia from physiology to therapy, hoping it will result in a rational decision-making process in an area not sufficiently supported by evidence.

Abstract
OBJECTIVE To evaluate the long-term costs and impact on quality of life of using prophylactic dextrose gel in patients at increased risk of developing neonatal hypoglycemia. STUDY DESIGN A cost-utility analysis was performed from the perspective of the health system, using a decision tree to model the long-term clinical outcomes of neonatal hypoglycemia, including cerebral palsy, epilepsy, vision disturbances, and learning disabilities, in patients at increased risk of neonatal hypoglycemia who received prophylactic dextrose gel vs standard care. Model parameters including likelihoods of hypoglycemia and admission to a neonatal intensive care unit, were based on the pre-Hypoglycemia Prevention with Oral Dextrose Study. Estimations of the likelihood of long-term condition(s), and their costs, were based on review of published literature. RESULTS Patients who received prophylactic dextrose gel incurred costs to the health system of around US $14 000 over an 18-year time horizon, accruing 11.25 quality-adjusted life-years, whereas those who did not receive prophylactic treatment incurred cost of around $16 000 and experienced a utility of 11.10 quality-adjusted life-years. CONCLUSIONS A prophylactic strategy of using dextrose gel in infants at increased risk of neonatal hypoglycemia is likely to be cost effective compared with standard care, to reduce the direct costs to the health system over an 18-year time horizon, and improve quality of life.

Abstract
BACKGROUND & AIMS In the absence of methodologically sound randomized controlled trials (RCTs), current recommendations for timing and amount of enteral nutrition (EN) in critically ill children are based on observational studies. These studies have associated achievement of a higher EN intake in critically ill children with improved outcome. Inherent to the observational design of these underlying studies, thorough insight in possible confounding factors to correct for is essential. We evaluated the associations between EN intake and 1) patient and daily clinical characteristics and 2) clinical outcomes adjusted for these patient and clinical characteristics during the first week of critical illness with a multivariable mixed model. METHODS This secondary analysis of the multicentre PEPaNIC RCT investigated a subgroup of critically ill children with daily prospectively recorded gastrointestinal symptoms and EN intake during the first week with multivariable analyses using two-part mixed effect models, including multiple testing corrections using Holm's method. These models combined a mixed-effects logistic regression for the dichotomous outcome EN versus no EN, and a linear mixed-effects model for the patients who received any EN intake. EN intake per patient was expressed as mean daily EN as % of predicted resting energy expenditure (% of EN/REE). Model 1 included 40 fixed effect baseline patient characteristics, and daily parameters of illness severity, feeding, medication and gastrointestinal symptoms. Model 2 included these patient and daily variables as well as clinical outcomes. RESULTS Complete data were available for 690 children. EN was provided in 503 (73%) patients with a start after a median of 2 (IQR 2-3) days and a median % of EN/REE of 38.8 (IQR 14.1-79.5) over the first week. Multivariable mixed model analyses including all patients showed that admission after gastrointestinal surgery (-49%EN/REE; p = 0.002), gastric feeding (-31% EN/REE; p < 0.001), treatment with inotropic agents (-22%EN/REE; p = 0.026) and large gastric residual volume (-64%EN/REE; p < 0.001) were independently associated with a low mean EN intake. In univariable analysis, low mean EN intake was associated with new acquired infections, hypoglycaemia, duration of PICU and hospital stay and duration of mechanical ventilation. However, after adjustment for confounders, these associations were no longer present, except for low EN and hypoglycaemia (-39%EN/REE; p = 0.018). CONCLUSIONS Several patient and clinical characteristics during the first week of critical illness were associated with EN intake. No independent associations were found between EN intake and clinical outcomes such as mortality, new acquired infection and duration of stay. These data emphasize the necessity of adequate multivariable adjustment in nutritional support research and the need for future RCTs investigating optimal EN intake.

Abstract
OBJECTIVES Within cost-effectiveness models, prevalence figures can inform transition probabilities. The methodological quality of studies can inform the choice of prevalence figures but no single obvious candidate tool exists for assessing quality of the observational epidemiological studies for selecting prevalence estimates. We aimed to compare different tools to assess the risk of bias of studies reporting prevalence, and develop and compare possible numerical scoring systems using these tools to set a threshold for inclusion of reports of prevalence in an economic analysis of neonatal hypoglycaemia. DESIGN Assessments of bias using two tools (Joanna Briggs Institute (JBI) Checklist for Prevalence Studies and a modified version of Risk Of Bias In Non-randomised Studies-of Interventions (ROBINS-I)) were compared for 18 studies relevant to a single setting (neonatal hypoglycaemia). Inclusions of studies for use in a decision analysis model were considered based on summary scores derived from these tools. RESULTS Both tools were considered easy to use and produced dispersed scores for each of the 40 study-outcome combinations. The modified ROBINS-I scores were more skewed than the JBI scores, particularly at higher thresholds. The studies selected for inclusion are generally the same using either tool; if 50% was used as the cut-off threshold using the Applicable Score both tools would yield the same results. However, the JBI tool is shorter and may be easier to interpret and apply to studies that do not involve a control group, while the modified ROBINS-I tool assesses more methodological detail in studies that include a control group. CONCLUSION Both tools performed well for systematically assessing studies that report on outcome prevalence and provided similar discrimination between studies for risk of bias. This convergent validity supports use of both tools for the purpose of assessing risk of bias and selecting studies that report prevalence for inclusion in economic analyses.

Abstract
OBJECTIVES To determine the proportion of well-appearing newborns screened for hypoglycemia, yield of specific screening criteria, and impact of screening on breastfeeding. STUDY DESIGN The retrospective study of well-appearing at-risk infants born ≥36 weeks' gestation with blood glucose (BG) measurements obtained ≤72 h of age. RESULTS Of 10,533 eligible well newborns, 48.7% were screened for hypoglycemia. Among tested infants, BG < 50 mg/dL occurred in 43% and 4.6% required intensive care for hypoglycemia. BG < 50 mg/dL was associated with lower rates of exclusive breastfeeding (22% vs 65%, p < 0.001). Infants screened due to late-preterm birth were most frequently identified as hypoglycemic. The fewest abnormal values occurred among appropriate weight, late-term infants of nondiabetic mothers. CONCLUSION Hypoglycemia risk criteria result in screening a large proportion of otherwise well newborns and negatively impact rates of exclusive breastfeeding. The risks and benefits of hypoglycemia screening recommendations should be urgently addressed.

Abstract
There are compelling preclinical data that common general anesthetics cause increased neuroapoptosis in juvenile animals. Retrospective studies demonstrate that young children exposed to anesthesia have school difficulties, which could be caused by anesthetic neurotoxicity, perioperative hemodynamic and homeostatic instability, underlying morbidity, or the neuroinflammatory effects of surgical trauma. Unnecessary procedures should be avoided. Baseline measures of blood pressure are important in determining perioperative blood pressure goals. Inadvertent hypocapnia or moderate hypercapnia and hyperoxia or hypoxia should be avoided. Pediatric patients should be maintained in a normothermic, euglycemic state with neutral positioning. Improving outcomes of infants and children requires the collaboration of anesthesiologists, surgeons, pediatricians and neonatologists.

Abstract
Infants who undergo surgical procedures in the first few months of life are at a higher risk of death or subsequent neurodevelopmental abnormalities. Although the pathogenesis of these outcomes is multifactorial, an understanding of the nature and pathogenesis of brain injury in these infants may assist the anesthesiologist in consideration of their day-to-day practice to minimize such risks. This review will summarize the main types of brain injury in preterm and term infants and their key pathways. In addition, the review will address key potential pathogenic pathways that may be modifiable including intraoperative hypotension, hypocapnia, hyperoxia or hypoxia, hypoglycemia, and hyperthermia. Each of these conditions may increase the risk of perioperative neurological injury, but their long-term ramifications are unclear.

Abstract
BACKGROUND Worldwide, many newborns who are preterm, small or large for gestational age, or born to mothers with diabetes are screened for hypoglycemia, with a goal of preventing brain injury. However, there is no consensus on a treatment threshold that is safe but also avoids overtreatment. METHODS In a multicenter, randomized, noninferiority trial involving 689 otherwise healthy newborns born at 35 weeks of gestation or later and identified as being at risk for hypoglycemia, we compared two threshold values for treatment of asymptomatic moderate hypoglycemia. We sought to determine whether a management strategy that used a lower threshold (treatment administered at a glucose concentration of <36 mg per deciliter [2.0 mmol per liter]) would be noninferior to a traditional threshold (treatment at a glucose concentration of <47 mg per deciliter [2.6 mmol per liter]) with respect to psychomotor development at 18 months, assessed with the Bayley Scales of Infant and Toddler Development, third edition, Dutch version (Bayley-III-NL; scores range from 50 to 150 [mean {±SD}, 100±15]), with higher scores indicating more advanced development and 7.5 points (one half the SD) representing a clinically important difference). The lower threshold would be considered noninferior if scores were less than 7.5 points lower than scores in the traditional-threshold group. RESULTS Bayley-III-NL scores were assessed in 287 of the 348 children (82.5%) in the lower-threshold group and in 295 of the 341 children (86.5%) in the traditional-threshold group. Cognitive and motor outcome scores were similar in the two groups (mean scores [±SE], 102.9±0.7 [cognitive] and 104.6±0.7 [motor] in the lower-threshold group and 102.2±0.7 [cognitive] and 104.9±0.7 [motor] in the traditional-threshold group). The prespecified inferiority limit was not crossed. The mean glucose concentration was 57±0.4 mg per deciliter (3.2±0.02 mmol per liter) in the lower-threshold group and 61±0.5 mg per deciliter (3.4±0.03 mmol per liter) in the traditional-threshold group. Fewer and less severe hypoglycemic episodes occurred in the traditional-threshold group, but that group had more invasive diagnostic and treatment interventions. Serious adverse events in the lower-threshold group included convulsions (during normoglycemia) in one newborn and one death. CONCLUSIONS In otherwise healthy newborns with asymptomatic moderate hypoglycemia, a lower glucose treatment threshold (36 mg per deciliter) was noninferior to a traditional threshold (47 mg per deciliter) with regard to psychomotor development at 18 months.

Risk Factor Assessment and the Incidence of Neonatal Hypoglycemia in the Postnatal Period. MEDICAL BULLETIN OF SISLI ETFAL HOSPITAL 2019; 53:389-394. [PMID: 32377114 PMCID: PMC7192288 DOI: 10.14744/semb.2019.08634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Accepted: 04/01/2019] [Indexed: 11/20/2022]
Abstract
Objectives The aim of this study was to evaluate risk factors used for the assessment of neonatal hypoglycemia and to examine the follow-up outcomes observed in the first 48 hours of postnatal life. Methods The records of infants born between 2015 and 2017 (3 years) at Şişli Hamidiye Etfal Training and Research Hospital who had a blood glucose level test performed within the first 24 hours after birth and who had follow-up results for 48 hours were included in the study. Data of gestational age; birth weight; gender; antenatal, natal and postnatal characteristics; blood glucose measurement method and time during the first 48 hours postpartum; glucose values and follow-up; nutritional status; and the need for hospitalization due to a low blood glucose value were recorded. Groups were created based on data of a diabetic mother, small for gestational age (SGA), large for gestational age (LGA), late preterm birth (34-36+6/7 gestational weeks), fetal distress, and feeding intolerance. Blood glucose measurement values and reasons for hypoglycemia and assessment were compared in subgroups. Results The data of 9480 infants were reviewed and included in the study. It was determined that blood levels were checked in 28.7% (n=2720). The mean birth weight and gestational age of the infants was 3143±804 g and 37.7±2.5 weeks, respectively. In the study group, 54.7% were male, and 57.5% were delivered via cesarean section. The most frequent factors prompting blood glucose measurement were LGA status (25.9%), prematurity (18%), transient tachypnea (17.3%), and SGA status (11.6%). Results revealed that the blood glucose values of 2009 (73.9%) infants were within normal limits, and there was no further monitoring of blood glucose level during the first 48 hours. In 711 (26.1%), a low blood glucose level finding led to follow-up assessment. The incidence of hospitalization with a preliminary diagnosis of hypoglycemia was 2.5% (n=67). Subgroup analysis indicated that at the first hour, the mean blood glucose value of the patients with multiple factors that were risks for hypoglycemia suggesting further evaluation was lower than those with transient tachypnea and fetal distress (p<0.001), and the mean blood glucose value of premature and LGA neonates were significantly lower than the infants of diabetic mothers at the sixth hour (p<0.001). Conclusion In the postnatal period, the rate of monitoring blood glucose levels in newborn babies was found to be 28.7% and the most commonly predicted risk factor was LGA babies. The frequency of postpartum hospitalization due to hypoglycemia was found to be 2.5%, and blood sugar levels were lower in the first hour in groups with multiple causes.

Abstract
Hypoglycemia is one of the most important and most common metabolic problems of the newborn because it poses a risk of neurological injury, if it is prolonged and recurs. Therefore, newborns who carry a risk of hypoglycemia should be fed immediately after delivery and the blood glucose level should be measured with intervals of 2-3 hours from the 30th minute after feeding. The threshold value for hypoglycemia is 40 mg/dL for the first 24 hours in symptomatic babies. In asymptomatic babies, this value is considered 25 mg/dL for 0-4 hours, 35 mg/dl for 4-24 hours, 50 mg/dL after 24 hours and 60 mg/dL after 48 hours. Screening should be performed with bed-side test sticks. When values near the limit value are obtained, confirmation with laboratory method should be done and treatment should be initiated, if necessary. The level targeted with treatment is considered 50 mg/dL in the postnatal first 48 hours before feeding, 60 mg/dL after 48 hours in babies with high risk and above 70 mg/dL in babies with permanent hypoglycemia. In cases in which the blood glucose level is below the threshold value and can not be increased by feeding, a glucose infusion of 6-8 mg/kg/min should be initiated. If symptoms accompany, a mini bolus of 10% dextrose (2 ml/kg/min) should accompany. Incements (2 mg/kg/min) should be performed, if the target level can not be achieved and decrements (2 ml/kg/ min) should be performed, if nutrition and stabilization is provided. The infusion should be discontinued, if the infusion rate decreases to 3-5 mg/ kg/min. If necessary, blood samples should be obtained during hypoglycemia in terms of differential diagnosis and the investigation should be performed following a 6-hour fasting period in babies fed enterally and at any time when the plasma glucose is <50 mg/dL in babies receiving parenteral infusion. The hypoglycemic babies in the risk group whose infusions have been terminated can be discharged, if the plasma glucose level is found to be at the target level for two times before feeding and babies with permanent, severe or resistant hypoglycemia can be discharged, if the plasma glucose level is >60 mg/dL following a 6-hour fast.

Abstract
OBJECTIVE To determine the association between potential neonatal risk factors and the quality of general movements (GMs) in preterm infants. STUDY DESIGN Prospective cohort study in 67 preterm infants. From video recordings made on Days 8 and 15, we scored the GMs as normal/abnormal and detailed aspects using the general movement optimality score (GMOS). Risk factors included respiratory insufficiency requiring mechanical ventilation, patent ductus arteriosus (PDA), and abnormal blood glucose levels. We used multiple regression analyses. RESULT On Day 8 after birth, the presence of a PDA remained in the multivariable model, explaining 17.1% of the variance in GMOS (beta, -0.414). On Day 15, duration of mechanical ventilation and frequency of hypoglycemic episodes explained 38.8% of the variance (betas, -0.382 and -0.466, respectively). CONCLUSION In preterm infants, PDA, duration of mechanical ventilation, and frequency of hypoglycemic episodes were associated with poorer neurological functioning during the first 2 weeks after birth.

Abstract
To determine whether moderate neonatal hypoglycemia in otherwise healthy infants is associated with adverse neurodevelopmental outcome in pre-school children. Population-based cohort study with prospectively collected register data from Sweden. All singletons born July 1st 2008 through December 31st 2012 (n = 101,060) in the region were included. Infants with congenital malformations, infants treated in neonatal intensive care unit, infants with inborn errors of metabolism and infants to mothers with diabetes were excluded. Infants were followed-up until 2014, at 2–6 years of age. Exposure was neonatal moderate hypoglycemia. Main outcomes were a compiled neurological or neurodevelopmental outcome; any developmental delay; motor developmental delay; and cognitive developmental delay. In adjusted regression analyses, the odds ratio (OR) of any neurological or neurodevelopmental outcome was 1.48 (95% confidence interval: 1.17–1.88) in hypoglycemic compared to normoglycemic infants. The adjusted risk of any developmental delay was more than doubled (OR 2.53 [1.71–3.73]), the adjusted risk of motor developmental delay was almost doubled (OR: 1.91 [1.06–3.44]) and the adjusted risk of cognitive developmental delay was almost tripled (OR 2.85 [1.70–4.76]). Infants with early neonatal hypoglycemia (< 6 h) had a double risk (OR 1.94 [1.30–2.89]) of any neurological or neurodevelopmental outcome and a tripled risk of cognitive developmental delay (OR 3.17 [1.35–7.43]), compared to normoglycemic infants. In the first population-based study on this topic, we show that moderate neonatal hypoglycemia is associated with increased risks of impaired neurodevelopment. Current treatment routines for uncomplicated hypoglycemia should be followed.

Early versus late parenteral nutrition in critically ill, term neonates: a preplanned secondary subgroup analysis of the PEPaNIC multicentre, randomised controlled trial. THE LANCET CHILD & ADOLESCENT HEALTH 2018; 2:505-515. [PMID: 30169323 DOI: 10.1016/s2352-4642(18)30131-7] [Citation(s) in RCA: 50] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 01/29/2018] [Revised: 04/05/2018] [Accepted: 04/06/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Previous randomised studies showed that withholding parenteral nutrition for 1 week of critical illness was superior to early initiation (<24-48 h) of parenteral nutrition in children and adults. However, neonates are considered more susceptible to macronutrient deficits. We investigated the effect of withholding parenteral nutrition for 1 week in critically ill, term neonates. METHODS We previously did a randomised, controlled study (PEPaNIC) of children aged up to 17 years admitted to paediatric intensive-care units (ICUs) in three hospitals in Belgium, Canada, and the Netherlands randomly assigned (1:1) to either standard care of parenteral nutrition initiated early within 24 h of admission to an ICU or late parenteral nutrition (where supplemental parenteral nutrition was withheld for 1 week after admission to the ICU). In this preplanned, secondary subanalysis of PEPaNIC, we looked at data from critically ill, term neonate participants (gestational age ≥37 weeks) aged up to 28 days (studied in overlapping age groups of ≤4 weeks, ≤1 week, and <1 day-ie, age at admission). In both the early parenteral nutrition and late parenteral nutrition groups, enteral nutrition was initiated as soon as possible and increased according to local protocols. Outcome assessors and investigators not directly involved in the paediatric ICU were not informed of treatment allocation. The primary endpoints were incidence of new infections and duration of paediatric ICU dependency (quantified as the number of days in the paediatric ICU and likelihood of earlier live discharge from the ICU), analysed based on intention to treat. Multivariable analyses were adjusted for the following risk factors: centre, Paediatric Logistic Organ Dysfunction score, Paediatric Index of Mortality 2 score, diagnosis group, and weight-for-age Z scores on admission. Secondary safety outcomes were mortality (at 90 days, during the intervention, in the paediatric ICU, and in the hospital) and hypoglycaemic incidents during the intervention. All patients in the respective groups were included in the safety analysis. FINDINGS Between June 18, 2012, and July 27, 2015, we included 209 participants in this substudy, 145 of whom were aged up to and including 1 week and 45 aged younger than 1 day. In neonates aged up to and including 4 weeks, late parenteral nutrition increased the likelihood of earlier live discharge from the paediatric ICU compared with early parenteral nutrition (adjusted hazard ratio [HR] 1·61, 95% CI 1·19-2·20; p=0·0021) but did not affect the risk of infection. The risk of infection in neonates aged up to and including 1 week and younger than 1 day was lower with late parenteral nutrition than with early parenteral nutrition (adjusted odds ratios [OR] 0·36, 95% CI 0·15-0·83, p=0·017; and 0·10, 0·01-0·64, p=0·015, respectively). For neonates aged up to and including 1 week, the likelihood of an earlier live discharge from the ICU was higher with late parenteral nutrition (adjusted HR 1·69, 95% CI 1·16-2·46; p=0·0063). For neonates younger than 1 day, adjusted HR was 1·95 (95% CI 0·93-4·12; p=0·078). Mortality at all studied timepoints was similar between the groups for all ages; however, in neonates aged up to and including 4 weeks and aged up to and including 1 week, the risk of hypoglycaemia was higher with late parenteral nutrition (23% vs 14%; adjusted OR 3·05, 95% CI 1·27-7·35, p=0·013; and 24% vs 14%; 3·57, 1·23-10·45, p=0·019, respectively. INTERPRETATION In critically ill, term neonates, withholding parenteral nutrition for 1 week was clinically superior to standard care of initiating parenteral nutrition within 24 h for short-term outcomes. However, withholding parenteral nutrition for 1 week significantly increased the risk of developing hypoglycaemia, which necessitates long-term follow-up of these children before late parenteral nutrition can be confidently recommended for this vulnerable patient group.

Abstract
BACKGROUND AND OBJECTIVE Neonatal hypoglycemia is a common problem, often requiring management in the NICU. Nonpharmacologic interventions, including early breastfeeding and skin-to-skin care (SSC), may prevent hypoglycemia and the need to escalate care. Our objective was to maintain mother-infant dyads in the mother-infant unit by decreasing hypoglycemia resulting in NICU transfer. METHODS Inborn infants ≥35 weeks' gestation with at least 1 risk factor for hypoglycemia were included. Using quality-improvement methodology, a bundle for at-risk infants was implemented, which included a protocol change focusing on early SSC, early feeding, and obtaining a blood glucose measurement in asymptomatic infants at 90 minutes. The primary outcome was the overall transfer rate of at-risk infants to the NICU. Secondary outcomes were related to protocol adherence. Balancing measures, including the rate of symptomatic hypoglycemia and sepsis evaluations, were monitored. Statistical process control charts using standard interpretation rules were used to monitor for improvement in key aims. RESULTS For infants at risk for hypoglycemia, the NICU transfer rate decreased from 17% to 3% overall. Documented early feeding and SSC in at-risk newborns increased. The percent of at-risk infants transferred to the NICU who did not require intravenous dextrose decreased from 5% at baseline to 0.7% after intervention. There were no adverse outcomes observed in the period before or after the intervention. CONCLUSIONS The implementation of a quality-improvement intervention promoting SSC and early feeding in at-risk infants was associated with a decreased rate of transfer to the NICU for hypoglycemia.

Abstract
Glucose, like oxygen, is of fundamental importance for any living being and it is the major energy source for the fetus and the neonate during gestation. The placenta ensures a steady supply of glucose to the fetus, while birth marks a sudden change in substrate delivery and a major change in metabolism. Hypoglycemia is one of the most common pathologies encountered in the neonatal intensive care unit and affects a wide range of neonates. Preterm, small for gestational age (GA) and intra-uterine growth restricted neonates are especially vulnerable due to their lack of metabolic reserves and associated co-morbidities. Nearly 30-60% of these high-risk infants are hypoglycemic and require immediate intervention. Preterm neonates are uniquely predisposed to developing hypoglycemia and its associated complications due to their limited glycogen and fat stores, inability to generate new glucose using gluconeogenesis pathways, have higher metabolic demands due to a relatively larger brain size, and are unable to mount a counter-regulatory response to hypoglycemia. In this review we will discuss the epidemiology; pathophysiology; clinical presentation; management and neurodevelopmental outcomes in affected infants and summarize evidence to develop a rational and scientific approach to this common problem.

Abstract
Nutrition of newborn infants, particularly of those born preterm, has advanced substantially in recent years. Extremely preterm infants have high nutrient demands that are challenging to meet, such that growth faltering is common. Inadequate growth is associated with poor neurodevelopmental outcomes, and although improved early growth is associated with better cognitive outcomes, there might be a trade-off in terms of worse metabolic outcomes, although the contribution of early nutrition to these associations is not established. New developments include recommendations to increase protein supply, improve formulations of parenteral lipids, and provide mineral supplements while encouraging human milk feeding. However, high quality evidence of the risks and benefits of these developments is lacking. Clinical trials are also needed to assess the effect on preterm infants of experiencing the smell and taste of milk, to determine whether boys and girls should be fed differently, and to test effects of insulin and IGF-1 supplements on growth and developmental outcomes. Moderate-to-late preterm infants have neonatal nutritional challenges that are similar to those infants born at earlier gestations, but even less high quality evidence exists upon which to base clinical decisions. The focus of research in nutrition of infants born at term is largely directed at new formula products that will improve cognitive and metabolic outcomes. Providing the most effective nutrition to preterm infants should be prioritised as an important focus of neonatal care research to improve long-term metabolic and developmental outcomes.

Abstract
Lower blood glucose values are common in the healthy neonate immediately after birth as compared to older infants, children, and adults. These transiently lower glucose values improve and reach normal ranges within hours after birth. Such transitional hypoglycemia is common in the healthy newborn. A minority of neonates experience a more prolonged and severe hypoglycemia, usually associated with specific risk factors and possibly a congenital hypoglycemia syndrome. Despite the lack of a specific blood glucose value that defines hypoglycemia, concern for substantial neurologic morbidity in the neonatal population has led to the generation of guidelines by both the American Academy of Pediatrics (AAP) and the Pediatric Endocrine Society (PES). Similarities between the 2 guidelines include recognition that the transitional form of neonatal hypoglycemia likely resolves within 48 hours after birth and that hypoglycemia that persists beyond that duration may be pathologic. One major difference between the 2 sets of guidelines is the goal blood glucose value in the neonate. This article reviews transitional and pathologic hypoglycemia in the neonate and presents a framework for understanding the nuances of the AAP and PES guidelines for neonatal hypoglycemia.

Abstract
A consistent definition for neonatal hypoglycemia in the first 48 h of life continues to elude us. Enhanced understanding of metabolic disturbances and genetic disorders that underlie alterations in postnatal glucose homeostasis has added useful information to understanding transitional hypoglycemia. This growth in knowledge still has not led to what we need to know: "How low is too low and for how long?" This article reviews the current state of understanding of neonatal hypoglycemia and how different approaches reach different "expert" opinions.

Abstract
Neonatal hypoglycaemia is common, and screening and treatment of babies considered at risk is widespread, despite there being little reliable evidence upon which to base management decisions. Although there is now evidence about which babies are at greatest risk, the threshold for diagnosis, best approach to treatment and later outcomes all remain uncertain. Recent studies suggest that treatment with dextrose gel is safe and effective and may help support breast feeding. Thresholds for intervention require a wide margin of safety in light of information that babies with glycaemic instability and with low glucose concentrations may be associated with a higher risk of later higher order cognitive and learning problems. Randomised trials are urgently needed to inform optimal thresholds for intervention and appropriate treatment strategies.

Abstract
BACKGROUND AND OBJECTIVES Neonatal hypoglycemia has been associated with abnormalities on brain imaging and a spectrum of developmental delays, although historical and recent studies show conflicting results. We compared the cognitive, academic, and behavioral outcomes of preterm infants with neonatal hypoglycemia with those of normoglycemic controls at 3 to 18 years of age. METHODS A secondary analysis of data from the Infant Health and Development Program, a national, multisite, randomized controlled longitudinal intervention study of long-term health and developmental outcomes in preterm infants. Of the 985 infants enrolled in the Infant Health and Development Program, 745 infants had glucose levels recorded. Infants were stratified into 4 groups by glucose level. By using standardized cognitive, academic, and behavioral assessments performed at 3, 8, and 18 years of age, we compared groups after adjusting for intervention status, birth weight, gestational age, sex, severity of neonatal course, race, maternal education, and maternal preconception weight. RESULTS No significant differences were observed in cognitive or academic skills between the control and effected groups at any age. Participants with more severe neonatal hypoglycemia reported fewer problem behaviors at age 18 than those without hypoglycemia. CONCLUSIONS No significant differences in intellectual or academic achievement were found between preterm infants with and without hypoglycemia. A statistical difference was found in behavior at age 18, with hypoglycemic children showing fewer problematic behaviors than normoglycemic children. This difference was not clinically meaningful. Using extended outcomes, our results are consistent with previous studies that found no significant neurodevelopmental outcomes associated with neonatal hypoglycemia in preterm-born children.

Abstract
BACKGROUND Neonatal hypoglycaemia, a common condition, can be associated with brain injury. It is frequently managed by providing infants with an alternative source of glucose, given enterally with formula or intravenously with dextrose solution. This often requires that mother and baby are cared for in separate environments and may inhibit breast feeding. Dextrose gel is simple and inexpensive and can be administered directly to the buccal mucosa for rapid correction of hypoglycaemia, in association with continued breast feeding and maternal care. OBJECTIVES To assess the effectiveness of dextrose gel in correcting hypoglycaemia and in reducing long-term neurodevelopmental impairment. SEARCH METHODS We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Web of Science from inception of the database to February 2016. We also searched international clinical trials networks and handsearched proceedings of specific scientific meetings. SELECTION CRITERIA Randomised and quasi-randomised studies comparing dextrose gel versus placebo, no treatment or other therapies for treatment of neonatal hypoglycaemia. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data and did not assess publications for which they themselves were study authors. MAIN RESULTS We included two trials involving 312 infants. No data were available for correction of hypoglycaemia for each hypoglycaemic event. We found no evidence of a difference between dextrose gel and placebo gel for major neurosensory disability at two-year follow-up (risk ratio (RR) 6.27, 95% confidence interval (CI) 0.77 to 51.03; one trial, n = 184; quality of evidence very low). Dextrose gel compared with placebo gel or no gel did not alter the need for intravenous treatment for hypoglycaemia (typical RR 0.78, 95% CI 0.46 to 1.32; two trials, 312 infants; quality of evidence very low). Infants treated with dextrose gel were less likely to be separated from their mothers for treatment of hypoglycaemia (RR 0.54, 95% CI 0.31 to 0.93; one trial, 237 infants; quality of evidence moderate) and were more likely to be exclusively breast fed after discharge (RR 1.10, 95% CI 1.01 to 1.18; one trial, 237 infants; quality of evidence moderate). Estimated rise in blood glucose concentration following dextrose gel was 0.4 mmol/L (95% CI -0.14 to 0.94; one trial, 75 infants). Investigators in one trial reported no adverse outcomes (n = 237 infants). AUTHORS' CONCLUSIONS Treatment of infants with neonatal hypoglycaemia with 40% dextrose gel reduces the incidence of mother-infant separation for treatment and increases the likelihood of full breast feeding after discharge compared with placebo gel. No evidence suggests occurrence of adverse effects during the neonatal period or at two years' corrected age. Oral dextrose gel should be considered first-line treatment for infants with neonatal hypoglycaemia.

Abstract
PURPOSE OF REVIEW The screening and management for neonatal hypoglycemia remains a confusing and contentious problem in neonatology. The purpose of this article is to contrast recent recommendations from the American Academy of Pediatrics and the Pediatric Endocrine Society. RECENT FINDINGS Using different methodologies, the organizations have significant differences on whom to screen and what levels of glucose should be used for management. The identification of the first 48 h as a transitional hyperinsulinemic state is a new important concept. The neuroendocrine approach is contrasted with a neurodevelopmental strategy to find levels that exceed those associated with neuroglycopenia. SUMMARY The questions remain the same when it comes to screening and management of neonatal low-glucose levels. Recent outcome studies with differing results continue to add to the controversy as to what to do at the bedside. It is uncertain if universal screening of glucose levels in the first hours should be applied to all newborn infants. Persistent hypoglycemic syndromes must be identified prior to discharge.

Abstract
BACKGROUND Recent trials have questioned the benefit of early parenteral nutrition in adults. The effect of early parenteral nutrition on clinical outcomes in critically ill children is unclear. METHODS We conducted a multicenter, randomized, controlled trial involving 1440 critically ill children to investigate whether withholding parenteral nutrition for 1 week (i.e., providing late parenteral nutrition) in the pediatric intensive care unit (ICU) is clinically superior to providing early parenteral nutrition. Fluid loading was similar in the two groups. The two primary end points were new infection acquired during the ICU stay and the adjusted duration of ICU dependency, as assessed by the number of days in the ICU and as time to discharge alive from ICU. For the 723 patients receiving early parenteral nutrition, parenteral nutrition was initiated within 24 hours after ICU admission, whereas for the 717 patients receiving late parenteral nutrition, parenteral nutrition was not provided until the morning of the 8th day in the ICU. In both groups, enteral nutrition was attempted early and intravenous micronutrients were provided. RESULTS Although mortality was similar in the two groups, the percentage of patients with a new infection was 10.7% in the group receiving late parenteral nutrition, as compared with 18.5% in the group receiving early parenteral nutrition (adjusted odds ratio, 0.48; 95% confidence interval [CI], 0.35 to 0.66). The mean (±SE) duration of ICU stay was 6.5±0.4 days in the group receiving late parenteral nutrition, as compared with 9.2±0.8 days in the group receiving early parenteral nutrition; there was also a higher likelihood of an earlier live discharge from the ICU at any time in the late-parenteral-nutrition group (adjusted hazard ratio, 1.23; 95% CI, 1.11 to 1.37). Late parenteral nutrition was associated with a shorter duration of mechanical ventilatory support than was early parenteral nutrition (P=0.001), as well as a smaller proportion of patients receiving renal-replacement therapy (P=0.04) and a shorter duration of hospital stay (P=0.001). Late parenteral nutrition was also associated with lower plasma levels of γ-glutamyltransferase and alkaline phosphatase than was early parenteral nutrition (P=0.001 and P=0.04, respectively), as well as higher levels of bilirubin (P=0.004) and C-reactive protein (P=0.006). CONCLUSIONS In critically ill children, withholding parenteral nutrition for 1 week in the ICU was clinically superior to providing early parenteral nutrition.

Abstract
PURPOSE OF REVIEW This article describes the current best available evidence on optimal nutrition in the paediatric intensive care based on different levels of outcome, which can be divided in surrogate and hard clinical outcome parameters. RECENT FINDINGS Undernutrition is associated with increased morbidity and mortality, whereas in specific cohorts of critically ill children, such as those with burn injury, obesity is associated with more complications, longer length of stay, and decreased likelihood of survival. There is a relation with adequacy of delivery of enteral nutrition and the amount of protein on length of hospital stay, neurological status, and mortality. Studies relating organ function, other than skin healing after thermal injury, with the nutritional status are scarce. There is also a scarcity of data concerning long-term follow-up and health economics. SUMMARY Until now, there are no randomized controlled trials which have investigated a causal relation between different feeding regimens on the nutritional status and short and long-term outcome. As a result current optimal nutritional strategies are based on small trials with surrogate outcome parameters. Prospective randomized studies are needed with nutritional and/or metabolic interventions to come to an optimal feeding strategy for critically ill children.
