Abstract
OBJECTIVE The aim of this study was to determine which late-preterm (35-36 weeks' gestational age [GA]) and term neonates with early-onset hypoglycemia in the first 72 hours postnatal required a continuous glucose infusion to achieve and successfully maintain euglycemia. STUDY DESIGN This is a retrospective cohort study of late preterm and term neonates born in 2010-2014 and admitted to the Mother-Baby Unit at Parkland Hospital who had laboratory-proven blood glucose concentration < 40 mg/dL (2.2 mmol/L) during the first 72 hours of life. Among the subgroup needing intravenous (IV) glucose infusion, we analyzed which factors predicted a maximum glucose infusion rate (GIR) ≥ 10 mg/kg/min. The entire cohort was randomly divided into a derivation cohort (n = 1,288) and a validation cohort (n = 1,298). RESULTS In multivariate analysis, the need for IV glucose infusion was associated with small size for GA, low initial glucose concentration, early-onset infection, and other perinatal variables in both cohorts. A GIR ≥ 10 mg/kg/min was required in 14% of neonates with blood glucose value < 20 mg/dL during the first 3 hours of observation. The likelihood of a GIR ≥ 10 mg/kg/min was associated with lower initial blood glucose value and lower umbilical arterial pH. CONCLUSION Need for IV glucose infusion was associated with small size for GA, low initial glucose concentration, early-onset infection, and variables associated with perinatal hypoxia-asphyxia. The likelihood of a maximum GIR ≥ 10 mg/kg/min was greater in neonates with lower blood glucose value during the first 3 hours of observation and lower umbilical arterial pH. KEY POINTS · We studied 51,973 neonates ≥ 35 weeks' GA.. · We established a model predicting the need for IV glucose.. · We also predicted the need for a high rate of IV glucose..

Abstract
Hypoglycemia is a common metabolic disorder that occurs in the neonatal period. Early identification of neonates at risk of developing hypoglycemia can optimize therapeutic strategies in neonatal care. This study aims to develop a machine learning model and implement a predictive application to assist clinicians in accurately predicting the risk of neonatal hypoglycemia within four hours after birth. Our retrospective study analyzed data from neonates born ≥35 weeks gestational age and admitted to the well-baby nursery between 1 January 2011 and 31 August 2021. We collected electronic medical records of 2687 neonates from a tertiary medical center in Southern Taiwan. Using 12 clinically relevant features, we evaluated nine machine learning approaches to build the predictive models. We selected the models with the highest area under the receiver operating characteristic curve (AUC) for integration into our hospital information system (HIS). The top three AUC values for the early neonatal hypoglycemia prediction models were 0.739 for Stacking, 0.732 for Random Forest and 0.732 for Voting. Random Forest is considered the best model because it has a relatively high AUC and shows no significant overfitting (accuracy of 0.658, sensitivity of 0.682, specificity of 0.649, F1 score of 0.517 and precision of 0.417). The best model was incorporated in the web-based application integrated into the hospital information system. Shapley Additive Explanation (SHAP) values indicated mode of delivery, gestational age, multiparity, respiratory distress, and birth weight < 2500 gm as the top five predictors of neonatal hypoglycemia. The implementation of our machine learning model provides an effective tool that assists clinicians in accurately identifying at-risk neonates for early neonatal hypoglycemia, thereby allowing timely interventions and treatments.

Abstract
OBJECTIVES Detecting and treating severe hypoglycemia promptly after birth is crucial due to its association with adverse long-term neurodevelopmental outcomes. However, limited data are available on the optimal timing of glucose screening in asymptomatic high-risk neonates prone to hypoglycemia. Risk factors associated with asymptomatic high-risk neonates include late prematurity ≥35 and <37 weeks gestation (LPT), small-for-gestational-age (SGA), large-for-gestational-age (LGA), and infant-of-a-diabetic mother (IDM). This study aims to determine the incidence and the impact of individual risk factors on early hypoglycemia (defined as blood glucose ≤25 mg/dL in the initial hour after birth) in asymptomatic high-risk neonates. METHODS All asymptomatic high-risk neonates ≥35 weeks gestation underwent early blood glucose screening within the first hour after birth (n=1,690). A 2-year retrospective analysis was conducted to assess the incidence of early neonatal hypoglycemia in this cohort and its association with hypoglycemia risk factors. RESULTS Out of the 9,919 births, 1,690 neonates (17 %) had risk factors for neonatal hypoglycemia, prompting screening within the first hour after birth. Incidence rates for blood glucose ≤25 mg/dL and ≤15 mg/dL were 3.1 and 0.89 %, respectively. Of concern, approximately 0.5 % of all asymptomatic at-risk neonates had a blood glucose value of ≤10 mg/dL. LPT and LGA were the risk factors significantly associated with early neonatal hypoglycemia. CONCLUSIONS Asymptomatic high-risk neonates, particularly LPT and LGA neonates, may develop early severe neonatal hypoglycemia identified by blood glucose screening in the first hour of life. Additional investigation is necessary to establish protocols for screening and managing asymptomatic high-risk neonates.

Abstract
BACKGROUND Neonatal hypoglycaemia is the most common metabolic disorder in infants, and may be influenced by maternal glycaemic control. This systematic review evaluated the effect of intrapartum maternal glycaemic control on neonatal hypoglycaemia. METHODS We included randomised controlled trials (RCTs), quasi-RCTs, non-randomised studies of interventions, and cohort or case-control studies that examined interventions affecting intrapartum maternal glycaemic control compared to no or less stringent control. We searched four databases and three trial registries to November 2023. Quality assessments used Cochrane Risk of Bias 1 or the Effective Public Health Practice Project Quality Assessment Tool. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE). Meta-analysis was performed using random-effects models analysed separately for women with or without diabetes. The review was registered prospectively on PROSPERO (CRD42022364876). RESULTS We included 46 studies of women with diabetes and five studies of women without diabetes: one RCT, 32 cohort and 18 case-control studies (11,273 participants). For women with diabetes, the RCT showed little to no difference in the incidence of neonatal hypoglycaemia between tight versus less tight intrapartum glycaemic control groups (76 infants, RR 1.00 (0.45, 2.24), p = 1.00, low certainty evidence). However, 11 cohort studies showed tight intrapartum glycaemic control may reduce neonatal hypoglycaemia (6,152 infants, OR 0.44 (0.31, 0.63), p < 0.00001, I2 = 58%, very low certainty evidence). For women without diabetes, there was insufficient evidence to determine the effect of tight intrapartum glycaemic control on neonatal hypoglycaemia. CONCLUSIONS Very uncertain evidence suggests that tight intrapartum glycaemic control may reduce neonatal hypoglycaemia in infants of women with diabetes. High-quality RCTs are required.

Abstract
Introduction Hypoglycemia is a critical concern in neonatal care, particularly among preterm infants. This study aims to investigate the frequency of hypoglycemia within the first 24 hours of life in preterm neonates, considering factors such as gestational age (GA), birth weight, and gender. Materials and methods A cross-sectional study was conducted from February to August 2021. The sample comprised 186 preterm infants selected through consecutive sampling. Data collection involved demographic information, glucose level monitoring, and symptom assessment. Results Of the 186 preterm neonates, 31.7% (n=59) experienced hypoglycemia within the first 24 hours, with feeding refusal being the predominant symptom. There was a significant difference in hypoglycemia occurrence between infants born before and after 32 weeks of gestation (p<0.05). Males were slightly more affected than females, although not statistically significant. Infants weighing less than 2 kg showed a higher susceptibility to hypoglycemia. Conclusion The early detection and management of hypoglycemia are crucial in preterm neonatal care. Close monitoring, especially in the initial four hours, is essential to prevent complications. Larger studies are warranted to confirm these findings and improve understanding and management strategies for hypoglycemia in preterm neonates, particularly within the first 24 hours of life.

Abstract
OBJECTIVE Antenatal corticosteroid (ACS) administration is standard practice for pregnant individuals delivering in the late preterm period, though no guidelines are in place for those with diabetes. This study aims to characterize the prevalence of neonatal hypoglycemia after ACS administration in pregnant individuals with diabetes delivering in the late preterm period. STUDY DESIGN This is a retrospective, single-center, case-control study of individuals with diabetes who delivered between 340/7 and 366/7 weeks' gestation at a large academic medical center from 2016 to 2021. A total of 169 individuals were included in the analysis; 87 received corticosteroids and 82 did not. The proportion of neonates with hypoglycemia, neonatal intensive care unit (NICU) admission, respiratory distress syndrome, and hyperbilirubinemia were compared between parents who received ACSs versus those who did not. RESULTS The prevalence of neonatal hypoglycemia (40.2 vs. 23.2%, p = 0.027), requiring treatment (40.3 vs. 22.4%, p = 0.041), and hyperbilirubinemia (35.6 vs 18.5%, p = 0.018) was greater for neonates born to individuals with diabetes who received late preterm ACSs compared with those who did not. There was no difference in NICU admission and respiratory distress between the groups. These results remained unchanged after controlling for confounders including gestational age at delivery and birth weight. CONCLUSION This study demonstrates that late preterm corticosteroid administration to pregnant individuals with diabetes increases the risk for neonatal hypoglycemia without changing the rates of respiratory morbidity. KEY POINTS · Late preterm ACS in diabetic patients resulted in higher rates of neonatal hypoglycemia.. · There are no differences in rates of respiratory distress syndrome and transient tachypnea of the newborn between the ACS group and control group.. · There was no noted difference in rate of NICU admission and length of stay between the two groups..

Abstract
BACKGROUND Hypoglycemia is the commonest metabolic abnormality encountered in newborns. Besides, there is a growing body of evidence that links the causes of early neonatal mortality to neonatal hypoglycemia in Tanzania. However exact factors associated with asymptomatic hypoglycemia in preterm newborns are not known. OBJECTIVE To assess factors associated with asymptomatic hypoglycemia among preterm newborns. MATERIALS AND METHODS A cross sectional, analytical hospital- based study was carried out at Dar es salaam public regional referral hospitals. Preterm newborns with asymptomatic hypoglycemia were the target population. Data on demographic and clinical characteristics of preterm newborns and their mothers were collected and analyzed using Epi-Info™ software version 7.4. Main data analysis was done by applying a multivariable binary logistic regression model with neonatal random glycaemia coded in a binary fashion at a cut-off point of 2.6 mmol/L. An α-level of 5% was used as a limit of type I error. RESULTS We recruited and analysed 217 preterm newborns within 6-24 hours post-delivery. Male: Female = 1.1:1 (females n = 105, 48.4%). Median glycemic level was 2.6 (IQR; 2.1-3.9) mmol/L. Median gestational age at delivery was 33 (IQR: 30-35) weeks. Breastfeeding within 1st hour post-delivery was a statistically significant factor against glycemic levels associated with hypoglycemia (OR; 0.123, 95%-CI; 0.052-0.287) in a fitted multivariable logistic regression model. CONCLUSION About half of all preterm newborns studied had glycemic values in a statistical range associated with hypoglycemia. Exclusive breast feeding within 1st hour post-delivery was associated with glycemic levels protective from risk of asymptomatic neonatal hypoglycemia. RECOMMENDATIONS Exclusive breastfeeding practices within 1st hour post-delivery may need to be emphasized to all expectant mothers in order to avoid potential risk of asymptomatic hypoglycemia in preterm newborns.

Abstract
Low blood concentrations of glucose (hypoglycaemia) soon after birth are common because of the delayed metabolic transition from maternal to endogenous neonatal sources of glucose. Because glucose is the main energy source for the brain, severe hypoglycaemia can cause neuroglycopenia (inadequate supply of glucose to the brain) and, if severe, permanent brain injury. Routine screening of infants at risk and treatment when hypoglycaemia is detected are therefore widely recommended. Robust evidence to support most aspects of management is lacking, however, including the appropriate threshold for diagnosis and optimal monitoring. Treatment is usually initially more feeding, with buccal dextrose gel, followed by intravenous dextrose. In infants at risk, developmental outcomes after mild hypoglycaemia seem to be worse than in those who do not develop hypoglycaemia, but the reasons for these observations are uncertain. Here, the current understanding of the pathophysiology of neonatal hypoglycaemia and recent evidence regarding its diagnosis, management, and outcomes are reviewed. Recommendations are made for further research priorities.

Abstract
High rates of academic underachievement at 9-10 years have been identified in children born at risk of neonatal hypoglycaemia. This study investigated the stability of behaviour from early to mid-childhood and how this relates to academic outcomes in children born with at least one risk factor of neonatal hypoglycaemia in Aotearoa, New Zealand. Behaviour data was collected using the Bayley Scales of Infant and Toddler Development, Child Behaviour Checklist 1.5-5, and the Strengths and Difficulties Questionnaire for 466 children (52 % male; 27 % Māori, 60 % New Zealand European, 2 % Pacific, 11 % Other) at multiple timepoints between ages 2 and 10 years. Academic data was collected at 9-10 years using the e-asTTle online learning and assessment tool. Findings revealed a link between early childhood behaviour and academic outcomes could be detected as early as age 2, suggesting that identifying and addressing early behavioural issues in children at risk of neonatal hypoglycaemia could aid in targeted interventions.

Abstract
AIM Improved identification and treatment of infants at risk of hypoglycaemia using evidence-based guidelines. METHODS Design: Prospective, multidisciplinary quality improvement project (QIP). SETTING Tertiary maternity hospital, Dublin (2016-2023). SUBJECTS Infants at risk for neonatal hypoglycaemia. INTERVENTION Plan-Do-Study-Act methodology. A hospital-wide survey and ongoing audit informed our initiatives including staff education, antenatal maternal education and standardisation of equipment. Our guidelines were continually evaluated and updated based on emerging evidence. MAIN OUTCOME MEASURES Neonatal unit (NNU) admissions, adherence to guidelines and use of glucose gel. RESULTS NNU admissions decreased by 70%, from 3% (118/3883) to 0.9% (34/3806 infants). The number requiring an IV glucose bolus reduced from 25% (29/118) to 6% (2/34). Improved antenatal education, antenatal expression of colostrum and early and frequent feeding also contributed to a reduction in glucose gel use of 94% (1009 tubes in 2018-v-62 in 2022). There were no adverse side effects related to hypoglycaemia. CONCLUSION Our QIP resulted in a significant reduction in NNU admissions leading to significant cost reductions and NNU workload. More importantly, this resulted in less maternal-infant separation and potentially less parental anxiety and a more supportive environment for breastfeeding. These low-cost initiatives can be implemented in other tertiary maternity hospitals to improve maternity and newborn care.

Abstract
Executive function plays an important role in promoting learning and social-emotional development in children. Neonatal hypoglycemia associates with executive function difficulties at 4.5 years, but little is known about the development of executive function over time in children born at risk of neonatal hypoglycemia. We aimed to describe the stability of executive function from early to mid-childhood in children born at risk of neonatal hypoglycemia and its association with neonatal hypoglycemia. Participants in a prospective cohort study of infants born at risk for neonatal hypoglycemia were assessed at ages 2, 4.5, and 9-10 years. We assessed executive function with batteries of performance-based and questionnaire-based measures, and classified children into one of four stability groups (persistent typical, intermittent typical, intermittent difficulty, and persistent difficulty) based on dichotomized scores (typical versus low at each age). Multinomial logistic regression was used to determine the associations between neonatal hypoglycemia and executive function stability groups. Three hundred and nine children, of whom 197 (64%) experienced neonatal hypoglycemia were assessed. The majority of children had stable and typical performance-based (63%) and questionnaire-based (68%) executive function across all three ages. Around one-third (30-36%) of children had transient difficulties, and only a few (0.3-1.9%) showed persistent difficulties in executive function at all ages. There was no consistent evidence of an association between neonatal hypoglycemia and the stability of executive function. Neonatal hypoglycemia does not appear to predict a specific pattern of development of executive function in children born at risk.

Abstract
Background Neonatal hypoglycemia has been a cause for concern due to increasingly frequent reports of long-term sequelae, leading to undue concern and inadvertent administration of formula feeds. Though hypoglycemia is usually encountered only in neonates with classical risk factors, hypoglycemia is also rarely seen even in babies with no known risk factors. These babies may present only with sequelae in later childhood. Methods This is a hospital-based observational, prospective study. We included 299 exclusively breastfed neonates who were shifted to mother's side with no congenital malformation or need for neonatal intensive care unit (NICU) admission. The neonates were studied in two groups: " At Risk" and "No Risk." The "At Risk" group included babies with known risk factors like low birth weight, late preterm (34-36 weeks), small for gestational age (birth weight <10th centile), infant of a diabetic mother, or large for gestational age (birth weight >90th centile). Hypoglycemia was the primary outcome measured independent of feeding time for both groups. For the "At Risk" group, monitoring was done at 0, 1, 2, 3, 4, 12, 24 plus 48 h. For the "Not At Risk" group, it was done at 12 and 24 h of life. The factors associated with both groups were studies as the secondary outcome. Results and Conclusion Out of 299 exclusively breastfed neonates, 13% were hypoglycemic. 27.06% were hypoglycemic in the "At Risk" group. In the "At Risk" group, low birth weight and primiparity were significant risk factors. The incidence of hypoglycemia in the "No Risk" group was 1.80%. Breast problems and breastfeeding problems, low education status of mother, young age, and primiparity were significant risk factors in the "No Risk" group.

Abstract
Importance Neonatal hypoglycemia is common, occurring in up to 50% of infants at risk for hypoglycemia (infant of diabetic mother [IDM], small for gestational age [SGA], large for gestational age [LGA], and preterm) and is associated with long-term neurodevelopmental impairment. Guidelines recommend screening infants at risk of hypoglycemia. The proportion of infants who require screening for neonatal hypoglycemia is unknown. Objective To determine the proportion of infants eligible for neonatal hypoglycemia screening using criteria from the highest-scoring critically appraised clinical guideline. Design, Setting, and Participants This systematic review of the literature was conducted to identify clinical practice guidelines for neonatal hypoglycemia and took place at a tertiary maternity hospital in Auckland, New Zealand. Eligible guidelines were critically appraised using the Appraisal of Guidelines for Research and Evaluation II tool. Using screening criteria extracted from the highest-scoring guideline, the proportion of infants eligible for neonatal hypoglycemia screening was determined in a retrospective observational cohort study of infants born January 1, 2004, to December 31, 2018. Data were analyzed by logistic regression. Infant participants were included if gestational age was 35 weeks or more, birth weight was 2000 g or more, and they were not admitted to a neonatal intensive care unit less than 1 hour after birth. The data were analyzed from November 2022 through February 2023. A total of 101 372 infants met the inclusion criteria. Exposure Risk factors for neonatal hypoglycemia. Main Outcome Proportion of infants eligible for neonatal hypoglycemia screening. Results The study team screened 2366 abstracts and 18 guidelines met inclusion criteria for appraisal. There was variability in the assessed quality of guidelines and a lack of consensus between screening criteria. The highest-scoring guideline defined screening criteria as: IDM, preterm (less than 37 weeks' gestation), SGA (less than 10th percentile), birth weight of less than 2500 g or more than 4500 g, LGA (more than 90th percentile), or gestational age more than 42 weeks. A total of 101 372 infants met criteria for inclusion in the cohort study; median (IQR) gestational age was 39 (38-40) weeks and 51% were male. The overall proportion of infants eligible for screening was 26.3%. There was an increase in the proportion of eligible infants from 25.6% to 28.5% over 15 years, which was not statistically significant after adjustment for maternal age, body mass index, ethnicity, and multiple pregnancy (odds ratio, 0.99; 95% CI, 0.93-1.03; change in proportion per year). Conclusion A systematic review found that practice guidelines providing recommendations for clinical care of neonatal hypoglycemia were of variable quality with is a lack of consensus regarding definitions for infants at risk for hypoglycemia. In the cohort study, one-quarter of infants were eligible for hypoglycemia screening. Further research is required to identify which infants may benefit from neonatal hypoglycemia screening.

Abstract
OBJECTIVE To determine cerebral glucose concentration and its relationship with glucose infusion rate (GIR) and blood glucose concentration in neonatal encephalopathy during therapeutic hypothermia (TH). METHODS This was an observational study in which cerebral glucose during TH was quantified by magnetic resonance (MR) spectroscopy and compared with mean blood glucose at the time of scan. Clinical data (gestational age, birth weight, GIR, sedative use) that could affect glucose use were collected. The severity and pattern of brain injury on MR imaging were scored by a neuroradiologist. Student t test, Pearson correlation, repeated measures ANOVA, and multiple regression analysis were performed. RESULTS Three-hundred-sixty blood glucose values and 402 MR spectra from 54 infants (30 female infants; mean gestational age 38.6 ± 1.9 weeks) were analyzed. In total, 41 infants had normal-mild and 13 had moderate-severe injury. Median GIR and blood glucose during TH were 6.0 mg/kg/min (IQR 5-7) and 90 mg/dL (IQR 80-102), respectively. GIR did not correlate with blood or cerebral glucose. Cerebral glucose was significantly greater during than after TH (65.9 ± 22.9 vs 60.0 ± 25.2 mg/dL, P < .01), and there was a significant correlation between blood glucose and cerebral glucose during TH (basal ganglia: r = 0.42, thalamus: r = 0.42, cortical gray matter: r = 0.39, white matter: r = 0.39, all P < .01). There was no significant difference in cerebral glucose concentration in relation to injury severity or pattern. CONCLUSIONS During TH, cerebral glucose concentration is partly dependent on blood glucose concentration. Further studies to understand brain glucose use and optimal glucose concentrations during hypothermic neuroprotection are needed.

Abstract
AIM To examine the relationship between neonatal hypoglycaemia and specific areas of executive function and behaviour in mid-childhood. METHOD Participants in a prospective cohort study of infants born late preterm or at term at risk of neonatal hypoglycaemia were assessed at 9 to 10 years. We assessed executive function using performance-based (Cambridge Neuropsychological Tests Automated Battery) and questionnaire-based (Behavior Rating Inventory of Executive Function) measures and behaviour problems with the Strengths and Difficulties Questionnaire. Data are reported as adjusted odds ratio (aOR) with 95% confidence intervals, and standardized regression coefficients. RESULTS We assessed 480 (230 females, 250 males; mean age 9 years 5 months [SD 4 months, range 8 years 8 months-11 years 0 months]) of 587 eligible children (82%). There were no differences in performance-based executive function between children who did and did not experience neonatal hypoglycaemia (blood glucose <2.6 mmoL/L). However, children who experienced hypoglycaemia, especially if severe or recurrent, were at greater risk of parent-reported metacognition difficulties (aOR 2.37-3.71), parent-reported peer (aOR 1.62-1.89) and teacher-reported conduct (aOR 2.14 for severe hypoglycaemia) problems. Both performance- and questionnaire-based executive functions were associated with behaviour problems. INTERPRETATION Neonatal hypoglycaemia may be associated with difficulties in specific aspects of parent-reported executive functions and behaviour problems in mid-childhood.

Abstract
Hypoglycemia is due to defects in the metabolic systems involved in the transition from the fed to the fasting state or in the hormone control of these systems. In children, hypoglycemia is considered a metabolic-endocrine emergency, because it may lead to brain injury, permanent neurological sequelae and, in rare cases, death. Symptoms are nonspecific, particularly in infants and young children. Diagnosis is based on laboratory investigations during a hypoglycemic event, but it may also require biochemical tests between episodes, dynamic endocrine tests and molecular genetics. This narrative review presents the age-related definitions of hypoglycemia, its pathophysiology and main causes, and discusses the current diagnostic and modern therapeutic approaches.

Abstract
Hypoglycemia represents one of the most frequent metabolic disturbances of the neonate, associated with increased morbidity and mortality, especially if left untreated or diagnosed after the establishment of brain damage. The aim of this study was to review and compare the recommendations from the most recently published influential guidelines on the diagnosis, screening, prevention and management of this common neonatal complication. Therefore, a descriptive review of the guidelines from the American Academy of Pediatrics (AAP), the British Association of Perinatal Medicine (BAPM), the European Foundation for the Care of the Newborn Infants (EFCNI), the Queensland Clinical Guidelines-Australia (AUS), the Canadian Pediatric Society (CPS) and the Pediatric Endocrine Society (PES) on neonatal hypoglycemia was carried out. There is a consensus among the reviewed guidelines on the risk factors, the clinical signs and symptoms of NH, and the main preventive strategies. Additionally, the importance of early recognition of at-risk infants, timely identification of NH and prompt initiation of treatment in optimizing the outcomes of hypoglycemic neonates are universally highlighted. All medical societies, except PES, recommend screening for NH in asymptomatic high-risk and symptomatic newborn infants, but they do not provide consistent screening approaches. Moreover, the reviewed guidelines point out that the diagnosis of NH should be confirmed by laboratory methods of BGL measurement, although treatment should not be delayed until the results become available. The definition of NH lacks uniformity and it is generally agreed that a single BG value cannot accurately define this clinical entity. Therefore, all medical societies support the use of operational thresholds for the management of NH, although discrepancies exist regarding the recommended cut-off values, the optimal treatment and surveillance strategies of both symptomatic and asymptomatic hypoglycemic neonates as well as the treatment targets. Over the past several decades, ΝH has remained an issue of keen debate as it is a preventable cause of brain injury and neurodevelopmental impairment; however, there is no clear definition or consistent treatment policies. Thus, the establishment of specific diagnostic criteria and uniform protocols for the management of this common biochemical disorder is of paramount importance as it will hopefully allow for the early identification of infants at risk, the establishment of efficient preventive measures, the optimal treatment in the first hours of a neonate's life and, subsequently, the improvement of neonatal outcomes.

Abstract
Neonatal hypoglycemia affects up to 15% of all newborns. Despite the high prevalence there is no uniform definition of neonatal hypoglycemia, and existing guidelines differ significantly in terms of when and whom to screen for hypoglycemia, and where to set interventional thresholds and treatment goals. In this review, we discuss the difficulties to define hypoglycemia in neonates. Existing knowledge on different strategies to approach this problem will be reviewed with a focus on long-term neurodevelopmental outcome studies and results of interventional trials. Furthermore, we compare existing guidelines on the screening and management of neonatal hypoglycemia. We summarize that evidence-based knowledge about whom to screen, how to screen, and how to manage neonatal hypoglycemia is limited - particularly regarding operational thresholds (single values at which to intervene) and treatment goals (what blood glucose to aim for) to reliably prevent neurodevelopmental sequelae. These research gaps need to be addressed in future studies, systematically comparing different management strategies to progressively optimize the balance between prevention of neurodevelopmental sequelae and the burden of diagnostic or therapeutic procedures. Unfortunately, such studies are exceptionally challenging because they require large numbers of participants to be followed for years, as mild but relevant neurological consequences may not become apparent until mid-childhood or even later. Until there is clear, reproducible evidence on what blood glucose levels may be tolerated without negative impact, the operational threshold needs to include some safety margin to prevent potential long-term neurocognitive impairment from outweighing the short-term burden of hypoglycemia prevention during neonatal period.

Abstract
Over 25 years ago, the World Health Organization (WHO) acknowledged the importance of effective prevention, detection and treatment of neonatal hypoglycaemia, and declared it to be a global priority. Neonatal hypoglycaemia is common, linked to poor neurosensory outcomes and, if untreated, can cause seizures and death. Neonatal mortality in low and lower-middle income countries constitutes an estimated 89% of overall neonatal deaths. Factors contributing to high mortality rates include malnutrition, infectious diseases, poor maternal wellbeing and resource constraints on both equipment and staff, leading to delayed diagnosis and treatment. The incidence of neonatal hypoglycaemia in low and lower-middle income countries remains unclear, as data are not collected.Data from high-resource settings shows that half of all at-risk babies will develop hypoglycaemia, using accepted clinical thresholds for treatment. Most at-risk babies are screened and treated, with treatment aiming to increase blood glucose concentration and, therefore, available cerebral fuel. The introduction of buccal dextrose gel as a first-line treatment for neonatal hypoglycaemia has changed the care of millions of babies and families in high-resource settings. Dextrose gel has now also been shown to prevent neonatal hypoglycaemia.In low and lower-middle income countries, there are considerable barriers to resources which prevent access to reliable blood glucose screening, diagnosis, and treatment, leading to inequitable health outcomes when compared with developed countries. Babies born in low-resource settings do not have access to basic health care and are more likely to suffer from unrecognised neonatal hypoglycaemia, which contributes to the burden of neurosensory delay and death.

Abstract
OBJECTIVE In the antenatal late preterm steroids (ALPS) trial betamethasone significantly decreased short-term neonatal respiratory morbidity but increased the risk of neonatal hypoglycemia, diagnosed only categorically (<40 mg/dL). We sought to better characterize the nature, duration, and treatment for hypoglycemia. STUDY DESIGN Secondary analysis of infants from ALPS, a multicenter trial randomizing women at risk for late preterm delivery to betamethasone or placebo. This study was a reabstraction of all available charts from the parent trial, all of which were requested. Unreviewed charts included those lost to follow-up or from sites not participating in the reabstraction. Duration of hypoglycemia (<40 mg/dL), lowest value and treatment, if any, were assessed by group. Measures of association and regression models were used where appropriate. RESULTS Of 2,831 randomized, 2,609 (92.2%) were included. There were 387 (29.3%) and 223 (17.3%) with hypoglycemia in the betamethasone and placebo groups, respectively (relative risk [RR]: 1.69, 95% confidence interval [CI]: 1.46-1.96). Hypoglycemia generally occurred in the first 24 hours in both groups: 374/385 (97.1%) in the betamethasone group and 214/222 (96.4%) in the placebo group (p = 0.63). Of 387 neonates with hypoglycemia in the betamethasone group, 132 (34.1%) received treatment, while 73/223 (32.7%) received treatment in placebo group (p = 0.73). The lowest recorded blood sugar was similar between groups. Most hypoglycemia resolved by 24 hours in both (93.0 vs. 89.3% in the betamethasone and placebo groups, respectively, p = 0.18). Among infants with hypoglycemia in the first 24 hours, the time to resolution was shorter in the betamethasone group (2.80 [interquartile range: 2.03-7.03) vs. 3.74 (interquartile range: 2.15-15.08) hours; p = 0.002]. Persistence for >72 hours was rare and similar in both groups, nine (2.4%, betamethasone) and four (1.9%, placebo, p = 0.18). CONCLUSION In this cohort, hypoglycemia was transient and most received no treatment, with a quicker resolution in the betamethasone group. Prolonged hypoglycemia was uncommon irrespective of steroid exposure. KEY POINTS · Hypoglycemia was transient and approximately two-thirds received no treatment.. · Neonates in the ALPS trial who received betamethasone had a shorter time to resolution than those with hypoglycemia in the placebo group.. · Prolonged hypoglycemia occurred in approximately 2 out of 100 late preterm newborns, irrespective of antenatal steroid exposure..

Abstract
BACKGROUND Neonatal hypoglycemia is one of the most common causes of admission to neonatal intensive care unit requiring intravenous dextrose therapy. Administration of IV dextrose and transfer to the NICU may interfere with parent-infant bonding, breastfeeding, and has financial implications. OBJECTIVE Retrospective study to evaluate the effect of dextrose gel supplementation for asymptomatic hypoglycemia in reducing NICU admissions and intravenous dextrose therapy. METHOD A retrospective study conducted for eight months each before and after introduction of dextrose gel in the management of asymptomatic neonatal hypoglycemia. Asymptomatic hypoglycemic infants were given only feeds in pre dextrose gel period and dextrose gel along with feeds in the dextrose gel period. Rates of admission to NICU and the need of IV dextrose therapy were evaluated. RESULTS High risk characteristics (Prematurity, Large for Gestational Age, small for Gestational Age, Infants of diabetic mother etc.) were equally distributed among both the cohorts. Primary outcome results showed significant reduction in NICU admissions from 396/1801(22%) to 329/1783 (18.5%) (odds ratio, 95% CI 1.24(1.05-1.46, p 0.008). There was significant reduction in IV dextrose therapy requirement from 277/1405 (15.4%) to 182/1454 (10.2%) (odds ratio, 95% CI 1.59(1.31- 1.95, p < 0.001).Babies discharged on predominant breast feeding showed significant improvement from 237/396(59.8%) in the pre dextrose gel period to 240/329 (72.9%) (odds ratio, 95% CI 0.82(0.73-0.90, p < 0.001) in dextrose gel period. CONCLUSIONS Dextrose gel supplementation with feeds reduced NICU admissions, the need for parenteral dextrose therapy, avoided maternal separation and promoted breastfeeding.

Abstract
Background Neonates at risk of hypoglycemia are often roomed in with mothers, but there is paucity of literature on the occurrence of hypoglycemia in these exclusively breastfed high-risk neonates. The primary objective was to estimate the incidence of hypoglycaemia in high-risk neonates on exclusive breastfeeding. The secondary objectives were to study the time of presentation, symptoms of hypoglycaemia, and the various maternal and neonatal risk factors. Methods This prospective observational study was carried out in a tertiary care teaching hospital of eastern India between January 2017 and June 2018. All neonates roomed in with mothers with high-risk factors such as low birth weight, preterm, small for gestational age, large for gestational age and infants of diabetic mothers were included. All included neonates were exclusive breastfed and underwent blood glucose monitoring at 2, 6, 12, 24, 48 and 72 h of life using glucometer strips and also whenever clinical features suggested hypoglycaemia. Hypoglycemia was defined as the blood glucose level ≤46 mg/dL. Results Of a total of 250 neonates studied, 52 (20.8%) developed hypoglycaemia in first 72 h. Hypoglycaemia was detected in most at 2 h with the second peak at 48 h of age. Only 8 (3.2%) neonates had symptomatic hypoglycaemia with jitteriness being the commonest symptom, followed by lethargy and poor feeding. Conclusion There is a need to closely monitor the blood glucose levels for at least first 48 h in high-risk neonates roomed in with mothers on exclusive breastfeeding.

Abstract
OBJECTIVES To assess in newborns with neonatal encephalopathy (NE), presumptively related to a peripartum hypoxic-ischemic event, the frequency of dysglycemia and its association with neonatal adverse outcomes. STUDY DESIGN We conducted a secondary analysis of LyTONEPAL (Long-Term Outcome of Neonatal hypoxic EncePhALopathy in the era of neuroprotective treatment with hypothermia), a population-based cohort study including 545 patients with moderate-to-severe NE. Newborns were categorized by the glycemia values assessed by routine clinical care during the first 3 days of life: normoglycemic (all glycemia measurements ranged from 2.2 to 8.3 mmol/L), hyperglycemic (at least 1 measurement >8.3 mmol/L), hypoglycemic (at least 1 measurement <2.2 mmol/L), or with glycemic lability (measurements included at least 1 episode of hypoglycemia and 1 episode of hyperglycemia). The primary adverse outcome was a composite outcome defined by death and/or brain lesions on magnetic resonance imaging, regardless of severity or location. RESULTS In total, 199 newborns were categorized as normoglycemic (36.5%), 74 hypoglycemic (13.6%), 213 hyperglycemic (39.1%), and 59 (10.8%) with glycemic lability, based on the 2593 glycemia measurements collected. The primary adverse outcome was observed in 77 (45.8%) normoglycemic newborns, 37 (59.7%) with hypoglycemia, 137 (67.5%) with hyperglycemia, and 40 (70.2%) with glycemic lability (P < .01). With the normoglycemic group as the reference, the aORs and 95% 95% CIs for the adverse outcome were significantly greater for the group with hyperglycemia (aOR 1.81; 95% CI 1.06-3.11). CONCLUSIONS Dysglycemia affects nearly two-thirds of newborns with NE and is independently associated with a greater risk of mortality and/or brain lesions on magnetic resonance imaging.

Front Pediatr 2023; 11:1071206.

Abstract
For the past 70 years, controversy about hypoglycemia in newborn infants has focused on a numerical "definition of neonatal hypoglycemia", without regard to its mechanism. This ignores the purpose of screening newborns for hypoglycemia, which is to identify those with pathological forms of hypoglycemia and to prevent hypoglycemic brain injury. Recent clinical and basic research indicates that the three major forms of neonatal hypoglycemia are caused by hyperinsulinism (recognizing also that other rare hormonal or metabolic conditions may also present during this time frame). These include transitional hypoglycemia, which affects all normal newborns in the first few days after birth; perinatal stress-induced hypoglycemia in high-risk newborns, which afflicts ∼1 in 1,200 newborns; and genetic forms of congenital hyperinsulinism which afflict ∼1 in 10,000-40,000 newborns. (1) Transitional hyperinsulinism in normal newborns reflects persistence of the low glucose threshold for insulin secretion during fetal life into the first few postnatal days. Recent data indicate that the underlying mechanism is decreased trafficking of ATP-sensitive potassium channels to the beta-cell plasma membrane, likely a result of the hypoxemic state of fetal life. (2) Perinatal stress-induced hyperinsulinism in high-risk infants appears to reflect an exaggeration of this normal low fetal glucose threshold for insulin release due to more severe and prolonged exposure to perinatal hypoxemia. (3) Genetic hyperinsulinism, in contrast, reflects permanent genetic defects in various steps controlling beta-cell insulin release, such as inactivating mutations of the K ATP-channel genes. The purpose of this report is to review our current knowledge of these three major forms of neonatal hyperinsulinism as a foundation for the diagnosis and management of hypoglycemia in newborn infants. This includes selection of appropriate interventions based on underlying disease mechanism; combined monitoring of both plasma glucose and ketone levels to improve screening for infants with persistent forms of hypoglycemia; and ultimately to ensure that infants at risk of persistent hyperinsulinemic hypoglycemia are recognized prior to discharge from the nursery.

Glucose variability increases during minimally invasive procedures in very preterm infants. Eur J Pediatr 2023; 182:89-94. [PMID: 36201017 PMCID: PMC9829573 DOI: 10.1007/s00431-022-04641-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 09/23/2022] [Accepted: 09/28/2022] [Indexed: 01/21/2023]
Abstract
UNLABELLED The objective of this study is to assess the effect of neonatal procedures on glucose variability in very preterm infants. Preterm infants (≤ 32 weeks gestation and/or birthweight ≤ 1500 g) were started on continuous glucose monitoring (CGM) on day 2 of birth and monitored for 5 days. Minimally invasive (heel stick, venipunctures) and non-invasive (nappy change, parental presence) procedures were recorded. CGM data were analyzed 30 min before and after each procedure. The primary outcome was the coefficient of glucose variation (CV = SD/mean) before and after the procedure; SD and median glucose were also evaluated. We analyzed 496 procedures in 22 neonates (GA 30.5 weeks [29-31]; birthweight 1300 g [950-1476]). Median glucose did not change before and after each procedure, while CV and SD increased after heel prick (p = 0.017 and 0.030), venipuncture (p = 0.010 and 0.030), and nappy change (p < 0.001 and < 0.001), in the absence of a difference during parental presence. CONCLUSIONS Non-invasive and minimally invasive procedures increase glucose variability in the absence of changes of mean glucose. WHAT IS KNOWN • Minimally invasive procedures - including nappy change - may increase neonatal stress in preterm infants. WHAT IS NEW • Continuous glucose monitoring provides a quantitative measure of neonatal stress during neonatal care procedures demonstrating an increase of glucose variability.

Abstract
BACKGROUND Hypoglycemia is a significant problem for all neonates and requires minimally invasive and reliable monitoring. The primary objective of this study was to verify the safety and accuracy of the continuous glucose monitoring (CGM) of full-term neonates using Freestyle Libre, a flash glucose monitoring (FGM) device. METHODS The study was conducted on 20 neonates. Shortly after birth, we placed the FGM sensor on the outside of the neonates' thighs. We scanned the CGM values at 60, 120, 180, and 360 min after birth and simultaneously obtained blood glucose values with plantar capillaries by heel puncture. The neonates wore the sensors for up to 6 h and then they were removed. RESULTS Of the 75 data points to be measured, 65 points (86.7%) were obtained by scan. There was no change in the sensor attachment site in 12 of 18 completed cases in this study but we observed slight induration in four cases (22.2%) and slight redness in one case (5.5%) at the sensor puncture site. A moderate correlation was observed between the CGM and blood glucose values. The CGM values tended to be low at 120, 180, and 360 min after birth, and tended to be high only at 60 min after birth. CONCLUSIONS The CGM device was safe to wear on the neonate and the CGM data correlated well with blood glucose levels. There was dissociation between CGM data and blood glucose levels in the acute period soon after birth when the blood glucose levels changed rapidly.

Abstract
Background and objective Neonatal hypoglycemia (NH) is one of the most common causes of admission to the neonatal intensive care unit (NICU). Persistent NH despite adequate feeding and intravenous dextrose may often require medications to maintain normal blood glucose levels (BGL). Several medications are used in the management of persistent NH, such as glucagon, diazoxide, and octreotide. In this study, we aimed to determine the factors that predict the need for medications to treat persistent NH. Methods This was a retrospective cohort study conducted at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. Infants admitted to the NICU between 2015 and 2019 with hypoglycemia (capillary blood glucose <2.6 mmol/l) were eligible to be included in the study. A prespecified dataset was collected from electronic patient records, including birth weight (BW), APGAR scores, gestational age, BGL, maternal risk factors such as diabetes mellitus (DM), hypertension, or antenatal use of medications, and the NICU management during admission. Data analysis was performed using SPSS Statistics for Windows, version 27.0 (IBM Corp., Armonk, NY). Results A total of 89 neonates were admitted due to NH during the study period. Of them, 10 (11.2%) patients had received medication (diazoxide). Use of medication for persistent NH was significantly associated with maternal gestational diabetes/diabetes mellitus (GDM/DM) status (p=0.041), higher BW (p=0.001), and large for gestational age [LGA (defined as BW >90th percentile)] (p=0.014), severe hypoglycemia (mean glucose level of 1-1.5 mmol/l) at two hours of life and at admission, and elevated maximum glucose infusion rate (GIR). GIR for the medication-requiring cohort was 12.95 mg/kg/min and that for the non-medication-requiring cohort was 6.77 mg/kg/min (p<0.001). Conclusion Based on our findings, the need for using certain medications to treat persistent NH, such as diazoxide in neonates admitted with NH, can be predicted by factors such as maternal GDM/DM status, BW >90th percentile, very low BGL at two hours of age and on admission, and elevated GIR. Elevated maximum GIR was a leading indicator for using medications in the treatment of NH.

Risk of hypoglycemia by anthropometric measurements in neonates of mothers with diabetes. Eur J Pediatr 2022; 181:3483-3490.

Abstract
Macrosomia in neonates of diabetic women is a risk factor for neonatal hypoglycemia, with an over-risk for asymmetric macrosomia. This study aimed to study the association between anthropometric measurements and hypoglycemia in neonates of mothers treated for gestational diabetes. This is a secondary analysis of the INDAO trial study conducted between May 2012 and November 2016 in 13 French tertiary care university hospitals in 890 pregnant women with gestational diabetes treated with either insulin or glyburide. Neonatal anthropometric measurements were birthweight and weight-length ratio (WLR, defined as birth weight/length). Neonatal hypoglycemia was defined as capillary blood glucose below 36 mg/dL (2 mmol/L) or below 45 mg/dL (2.5 mmol/L) associated with clinical signs after 2 h of life. Their relationships were modeled with logistic regressions using fractional polynomials. Extreme categories of birthweight or WLR adjusted for gestational age at birth and sex were defined as Z-score < -1.28 or > 1.28. These categories were compared to Z-score between -1.28 and 1.28 by estimating odds ratios and confidence intervals for neonatal hypoglycemia. Neonatal hypoglycemia occurred in 9.1% of cases. The relationship between birthweight and WLR Z-scores and neonatal risk of hypoglycemia adjusted for maternal treatment was a U-shaped curve. Adjusted odds ratios for the risk of hypoglycemia were 9.6 (95% CI 3.5, 26.8) and 2.3 (95% CI 1.1, 4.9) for WLR Z-score below -1.28 and above 1.28, respectively, compared with WLR Z-score between -1.28 and 1.28. Conclusion: Birthweight Z-score was associated with the risk of neonatal hypoglycemia in neonates from mothers treated for gestational diabetes. The risk of neonatal hypoglycemia was increased for both extreme birthweight Z-scores, regardless of maternal treatment. Small for gestational age neonates of diabetic mothers require special attention for the risk of neonatal hypoglycemia. What is Known: • Macrosomia in neonates of diabetic women is a risk factor for neonatal hypoglycemia, with an over-risk for asymmetric macrosomia. Few retrospective studies have assessed the risk for neonatal hypoglycemia among small for gestational age neonates born to diabetic mothers. What is New: • The risk of neonatal hypoglycemia among neonates of diabetic mothers increased for both low and high weight-length ratio, regardless of maternal medicinal treatment, gestational age at birth, and sex of the newborn.

Abstract
Background The practice of therapeutic hypothermia (TH) is widely used for neonatal hypoxic-ischemic encephalopathy (HIE) despite its corresponding feeding strategies are still controversial. This randomized controlled trial (RCT) demonstrated to evaluate the effect of early vs. delayed enteral nutrition on the incidence of feeding intolerance (FI) and other association during TH. Methods This single center, parallel-group, and no-blinded RCT was processed in a level III, and academic neonatal intensive care unit. Infants who were diagnosed with HIE and undertaken TH from September 2020 to August 2021 were enrolled. Participants were randomized to receive enteral nutrition either during TH/rewarming (early enteral nutrition, EEN) or after TH (delayed enteral nutrition, DEN) according to a recommend enteral feeding protocol. All data were analyzed using SPSS 26.0 software with a p-value< 0.05 was considered statistically significant. Results Ninety-two infants were enrolled after randomization, but 12 (13.04%) cases including 3 (3.26%) deaths were excluded from eventually analyzed, who did not initiate or discontinue the intervention. 80 cases (42 and 38 in the EEN and DEN group, respectively) who completed the interventions were eventually analyzed. Besides initial time of enteral feeds, two groups had processed the same feeding method. Total 23 (25.0%) cases developed FI, and no difference of morbidity was found between two groups (23.4% vs 26.7%, p = 0.595; Log Rank, p = 0.803). There was no case died or developed late-onset bloodstream and no difference of the incidence of hypoglycemia or weight gain was found (p > 0.05). The percentage of infants who had not reaching the goal of full enteral feeding volume between the two groups was similar (21.43% vs 23.68%, p = 0.809). The average time of parenteral nutrition, reaching full enteral feeds and hospital stay were shorter in the EEN group compared with the DEN group with significant differences (8.81 ± 1.67 vs 10.61 ± 2.06 days, p < 0.001; 9.91 ± 1.88 vs 12.24 ± 2.50 days, p < 0.001; 12.55 ± 4.57 vs 16.47 ± 5.27 days, p = 0.001 respectively). Conclusions Compared with delayed enteral nutrition, introduction of early enteral nutrition according to a recommend feeding strategy for neonatal HIE undergoing TH may be feasible and safe.FI is frequent in this high-risk group of infants which should not be ignored during feeding process.

Abstract
Background Recurrent hypoglycemia (RH) is well known to impair awareness of hypoglycemia and increase the risk of severe hypoglycemia; the underlying mechanism requires further understanding. We aimed to investigate the metabolic characteristic profile for RH in type 2 diabetes mellitus (T2DM) patients and explore the potential metabolic mechanism and prevention strategies. Methods We screened 553 community-based T2DM patients. T2DM with RH (DH group, n=40) and T2DM without hypoglycemia (DC group, n=40) were assigned in the case-control study, matched by propensity score matching. Non-targeted, global metabolite profiling was conducted using ultra-high performance liquid chromatography-mass spectrometry. Principal component analysis and supervised projections to latent structures-discriminant analysis were constructed to evaluate the potential biomarkers. Metabolites with a fold change of >2.0 or <0.5, a t-test q-value <0.05, and variable importance in projection value of >1 were identified as significantly differential metabolites. MetaboAnalyst was performed to analyze the related metabolic pathways. Results We identified 12 significantly distinct metabolites as potential biomarkers of RH, which were enriched in five pathways; the caffeine metabolic pathway was the most dominant related one. Caffeine and its main downstream metabolites (theophylline and paraxanthine, all q <0.05) were significantly lower during RH. The combination of these metabolites can serve as a reliable predictor biomarker for RH (area under the curve = 0.88). Regarding lipid metabolism, triglyceride was upregulated (P=0.003) and the O-Acylcarnitine was downregulated (q < 0.001). Besides, RH was accompanied by lower phenylalanine (q=0.003) and higher cortisone (q=0.005) levels. Conclusions RH in T2DM is accompanied by caffeine, lipolysis, phenylalanine, and cortisone metabolism abnormalities. Caffeine might be a reliable candidate biomarker and potential prevention strategy for RH, but further validation studies are needed. Clinical Trial Registry Chi CTR 1900026361, 2019-10-3.

Abstract
Hypoglycemia results from an imbalance between glucose entering the blood compartment and glucose demand, caused by a defect in the mechanisms regulating postprandial glucose homeostasis. Hypoglycemia represents one of the most common metabolic emergencies in childhood, potentially leading to serious neurologic sequelae, including death. Therefore, appropriate investigation of its specific etiology is paramount to provide adequate diagnosis, specific therapy and prevent its recurrence. In the absence of critical samples for biochemical studies, etiological assessment of children with hypoglycemia may include dynamic methods, such as in vivo functional tests, and continuous glucose monitoring. By providing detailed information on actual glucose fluxes in vivo, proof-of-concept studies have illustrated the potential (clinical) application of dynamic stable isotope techniques to define biochemical and clinical phenotypes of inherited metabolic diseases associated with hypoglycemia. According to the textbooks, individuals with glycogen storage disease type I (GSD I) display the most severe hypoglycemia/fasting intolerance. In this review, three dynamic methods are discussed which may be considered during both diagnostic work-up and monitoring of children with hypoglycemia: 1) functional in vivo tests; 2) in vivo metabolic profiling by continuous glucose monitoring (CGM); 3) stable isotope techniques. Future applications and benefits of dynamic methods in children with hypoglycemia are also discussed.

Abstract
CONTEXT Although it is well-acknowledged that gestational diabetes mellitus (GDM) is associated with the increased risks of adverse pregnancy outcomes, the optimal strategy for screening and diagnosis of GDM is still a matter of debate. OBJECTIVE This study was conducted to demonstrate the noninferiority of less strict GDM screening criteria compared with the strict International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria with respect to maternal and neonatal outcomes. METHODS A cluster randomized noninferiority field trial was conducted on 35 528 pregnant women; they were scheduled to have 2 phases of GDM screening based on 5 different prespecified protocols including fasting plasma glucose in the first trimester with threshold of 5.1 mmol/L (92 mg/dL) (protocols A, D) or 5.6 mmol/L (100 mg/dL) (protocols B, C, E) and either a 1-step (GDM is defined if one of the plasma glucose values is exceeded [protocol A and C] or 2 or more exceeded values are needed [protocol B]) or 2-step approach (protocols D, E) in the second trimester. Guidelines for treatment of GDM were consistent with all protocols. Primary outcomes of the study were the prevalence of macrosomia and primary cesarean section (CS). The null hypothesis that less strict protocols are inferior to protocol A (IADPSG) was tested with a noninferiority margin effect (odds ratio) of 1.7. RESULTS The percentages of pregnant women diagnosed with GDM and assigned to protocols A, B, C, D, and E were 21.9%, 10.5%, 12.1%, 19.4%, and 8.1%, respectively. Intention-to-treat analyses satisfying the noninferiority of the less strict protocols of B, C, D, and E compared with protocol A. However, noninferiority was not shown for primary CS comparing protocol E with A. The odds ratios (95% CI) for macrosomia and CS were: B (1.01 [0.95-1.08]; 0.85 [0.56-1.28], C (1.03 [0.73-1.47]; 1.16 [0.88-1.51]), D (0.89 [0.68-1.17]; 0.94 [0.61-1.44]), and E (1.05 [0.65-1.69]; 1.33 [0.82-2.00]) vs A. There were no statistically significant differences in the adjusted odds of adverse pregnancy outcomes in the 2-step compared with the 1-step screening approaches, considering multiplicity adjustment. CONCLUSIONS The IADPSG GDM definition significantly increased the prevalence of GDM diagnosis. However, the less strict approaches were not inferior to other criteria in terms of adverse maternal and neonatal outcomes.

Abstract
OBJECTIVES To evaluate, using video documentation, the sensitivity, specificity, and interobserver reliability of visualizable signs of neonatal hypoglycemia at different glucose concentrations in neonates. STUDY DESIGN In a prospective cohort study of 145 neonates with and without risk factors for hypoglycemia, 430 videos were recorded before blood glucose measurements and analyzed by 10 blinded investigators of different professions. The primary outcome measures were sensitivity and specificity for clinical detection of hypoglycemia. RESULTS The overall sensitivity to detect low blood glucose (<55 mg/dL [<3.1 mmol/L]) based on signs was 30%, and the specificity was 82%. Significantly more investigators suspected hypoglycemia while viewing videos of infants with blood glucose levels of 46-54 mg/dL (2.6-3.0 mmol/L) and 30-45 mg/dL (1.7-2.5 mmol/L) compared with ≥55 mg/dL (≥3.1 mmol/L) (29 ± 3% and 31 ± 4% vs 18 ± 1%; P = .001; P = .007). After 48 hours of life, significantly more investigators suspected hypoglycemia in videos of infants with blood glucose levels of ≤45 mg/dL (≤2.5 mmol/L) compared with blood glucose levels of >45 mg/dL (>2.5 mmol/L) (28.9 ± 8.1% vs 10.9 ± 1.8%; P = .007). For blood glucose levels 30-45 mg/dL (1.7-2.5 mmol/L), sensitivity varied widely between investigators, ranging from 5% to 62%. Three hypoglycemic episodes <30 mg/dL (<1.7 mmol/L) were only partially recognized. CONCLUSIONS Clinical observation of signs is neither sensitive nor specific to detect neonatal hypoglycemia, and there are large interobserver differences. Thus, guidelines on neonatal hypoglycemia should reconsider whether distinguishing between asymptomatic and symptomatic hypoglycemia provides useful information for the management of neonatal hypoglycemia, because it may pose a risk for systematic under-recognition and undertreatment, leading to an increased risk for neurodevelopmental impairment.

Abstract
We developed a microfluidic device for the rapid analysis of biomarkers in small volumes of whole blood. This device includes an onboard plasma separation module connected to a downstream bioanalysis module in which plasma mixes with reagents and the results of a colorimetric assay are recorded. Actuation of onboard microvalves within a bioanalysis module creates active mixing conditions that allowed us to achieve solution homogeneity within 5 min. To demonstrate utility, we carried out glucose detection in our device. With 5 μL of whole blood as an input, our microfluidic device enabled a time-to-answer of 10 min with a limit of detection of 0.21 ± 0.04 mM for glucose. This device has immediate applications for rapid and sensitive monitoring of hypoglycemia at the point of care (POC). Furthermore, our automated microfluidic device represents a platform technology that may be used to detect other biomarkers in whole blood.

Abstract
BACKGROUND Although there is a wide breadth of literature on glucose homeostasis in infants, standardization of perioperative hypoglycemia diagnosis and management is lacking. AIMS Survey of academic pediatric anesthesiology departments across the USA to evaluate institutional policies regarding the perioperative use of glucose containing solutions in infants less than 6 months of age. METHODS A questionnaire was sent to 20 United States university affiliated academic pediatric anesthesiology departments. RESULTS The responses suggest that, in the centers surveyed, glucose administration in infants is largely practitioner dependent. Two respondents (10%) claim to have a departmental policy regarding glucose administration in infants less than 6 months of age. In premature infants, 75% of respondents administer glucose. When administering glucose, 75% of physicians surveyed replete infants at their maintenance intravenous fluid rate. There was discrepancy among practitioners regarding initiation of hypoglycemia treatment, 35% treat infants at a blood glucose level of 70 mg/dl, 30% at BG 60 mg/dl, 25% at 50 mg/dl, and 10% are unsure. DISCUSSION This survey highlights the lack of consensus, at least among pediatric anesthesiologists working in US academic centers, regarding blood glucose management in infants less than 6 months of age. There is a need to define the indications for using glucose containing solutions in infants during the perioperative period, their ideal content, the appropriate thresholds for hypo- and hyperglycemia as well as the optimal point-of care glucose monitoring intervals.

Abstract
BACKGROUND Labor represents a period of significant physical activity. Inefficient energy supply may delay labor process and even lead to cesarean delivery. Herein we investigated whether ingestion of a carbohydrate-rich beverage could reduce cesarean delivery in laboring women with epidural analgesia. METHODS This multicenter randomized trial was conducted in obstetrician-led maternity units of nine tertiary hospitals in China. Primigravidae with single term cephalic pregnancy who were preparing for vaginal birth under epidural analgesia were randomized to intake a carbohydrate-rich beverage or commercially available low-carbohydrate beverages during labor. The primary outcome was the rate of cesarean delivery. Secondary outcomes included maternal feeling of hunger, assessed with an 11-point scale where 0 indicated no hunger and 10 the most severe hunger, and maternal and neonatal blood glucose after childbirth. RESULTS Between 17 January 2018 and 20 July 2018, 2008 women were enrolled and randomized, 1953 were included in the intention-to-treat analysis. The rate of cesarean delivery did not differ between the two groups (11.3% [111/982] with carbohydrate-rich beverage vs. 10.9% [106/971] with low-carbohydrate beverages; relative risk 1.04, 95% CI 0.81 to 1.33; p = 0.79). Women in the carbohydrate-rich beverage group had lower subjective hunger score (median 3 [interquartile range 2 to 5] vs. 4 [2 to 6]; median difference - 1; 95% CI - 1 to 0; p < 0.01); their neonates had less hypoglycemia (1.0% [10/968] vs. 2.3% [22/956]; relative risk 0.45; 95% CI 0.21 to 0.94; p = 0.03) when compared with those in the low-carbohydrate beverage group. They also had higher rates of maternal hyperglycemia (6.9% [67/965] vs. 1.9% [18/953]; p < 0.01) and neonatal hyperglycemia (9.2% [89/968] vs. 5.8% [55/956]; p < 0.01), but none required special treatment. CONCLUSIONS For laboring primigravidae with epidural analgesia, ingestion of a carbohydrate-rich beverage compared with low-carbohydrate beverages did not reduce cesarean delivery, but relieved maternal hunger and reduced neonatal hypoglycemia at the expense of increased hyperglycemia of both mothers and neonates. Optimal rate of carbohydrate supplementation remains to be determined. TRIAL REGISTRATION www.chictr.org.cn ; identifier: ChiCTR-IOR-17011994 ; registered on 14 July 2017.

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.

Associations between neonatal hypoglycaemia and brain volumes, cortical thickness and white matter microstructure in mid-childhood: An MRI study. Neuroimage Clin 2022; 33:102943. [PMID: 35063925 PMCID: PMC8856905 DOI: 10.1016/j.nicl.2022.102943] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 01/11/2022] [Accepted: 01/13/2022] [Indexed: 11/11/2022]
Abstract
Neonatal hypoglycaemia is associated with damage to the brain in the acute phase. In mid-childhood, neonatal hypoglycaemia is associated with smaller brain regions. Deep grey matter regions such as the caudate and thalamus are implicated. Children with neonatal hypoglycemia had smaller occipital lobe cortical thickness. Grey matter may be especially vulnerable to long-term effects of neonatal hypoglycemia.
Neonatal hypoglycaemia is a common metabolic disorder that may cause brain damage, most visible in parieto-occipital regions on MRI in the acute phase. However, the long term effects of neonatal hypoglycaemia on the brain are not well understood. We investigated the association between neonatal hypoglycaemia and brain volumes, cortical thickness and white matter microstructure at 9–10 years. Children born at risk of neonatal hypoglycaemia at ≥ 36 weeks’ gestation who took part in a prospective cohort study underwent brain MRI at 9–10 years. Neonatal hypoglycaemia was defined as at least one hypoglycaemic episode (at least one consecutive blood glucose concentration < 2.6 mmol/L) or interstitial episode (at least 10 min of interstitial glucose concentrations < 2.6 mmol/L). Brain volumes and cortical thickness were computed using Freesurfer. White matter microstructure was assessed using tract-based spatial statistics. Children who had (n = 75) and had not (n = 26) experienced neonatal hypoglycaemia had similar combined parietal and occipital lobe volumes and no differences in white matter microstructure at nine years of age. However, those who had experienced neonatal hypoglycaemia had smaller caudate volumes (mean difference: −557 mm3, 95% confidence interval (CI), −933 to −182, p = 0.004) and smaller thalamus (−0.03%, 95%CI, −0.06 to 0.00; p = 0.05) and subcortical grey matter (−0.10%, 95%CI −0.20 to 0.00, p = 0.05) volumes as percentage of total brain volume, and thinner occipital lobe cortex (−0.05 mm, 95%CI −0.10 to 0.00, p = 0.05) than those who had not. The finding of smaller caudate volumes after neonatal hypoglycaemia was consistent across analyses of pre-specified severity groups, clinically detected hypoglycaemic episodes, and severity and frequency of hypoglycaemic events. Neonatal hypoglycaemia is associated with smaller deep grey matter brain regions and thinner occipital lobe cortex but not altered white matter microstructure in mid-childhood.

Abstract
Our lack of basic knowledge about the basic mechanisms of transitional hypoglycemia and other forms of hypoglycemia in newborns underlies the ongoing controversies over standards for managing these conditions. To address this deficiency, the authors evaluated regulation of insulin secretion in fetal, newborn, and adult rats. The results demonstrate that transitional hypoglycemia in normal neonates and persistent hypoglycemia in high-risk infants both reflect altered beta-cell insulin regulation. These findings provide a new foundation for improving detection and management and preventing hypoglycemic brain injury in normal neonates and, especially, in infants with persistent hypoglycemia and genetic forms of congenital hyperinsulinism.

Abstract
Congenital hyperinsulinism comprises a group of diseases characterized by a persistent hyperinsulinemic hypoglycemia, due to mutation in the genes involved in the regulation of insulin secretion. The severity and the duration of hypoglycemic episodes, primarily in the neonatal period, can lead to neurological impairment. Detecting blood sugar is relatively simple but, unfortunately, symptoms associated with hypoglycemia may be non-specific. Research in this field has led to novel insight in diagnosis, monitoring and treatment, leading to a better neurological outcome. Given the increased availability of continuous glucose monitoring systems that allow glucose level recognition in a minimally invasive way, monitoring the glycemic trend becomes easier and there are more possibilities of a better follow-up of patients. We aim to provide an overview of new available technologies and new discoveries and their potential impact on clinical practice, convinced that only with a better awareness of the disease and available tools we can have a better impact on CHI diagnosis, prevention and clinical sequelae.

Abstract
BACKGROUND Severe neonatal hypoglycemia may cause irreversible neurological sequelae. Although blood glucose (BG) screening in term neonates without risk factors for hypoglycemia (non-risk neonates) is not recommended in the current guidelines, severe hypoglycemia can occur in such neonates. To evaluate the necessity of BG screening in non-risk neonates, it is important to determine the accurate incidence of severe hypoglycemia in those neonates. METHODS We conducted a 10 year survey of all normal-weight term neonates diagnosed with severe neonatal hypoglycemia who were treated at secondary- and tertiary-level neonatal centers in Toyama Prefecture, Japan, between January 2011 and December 2020. RESULTS During the study period, 11 cases of severe neonatal hypoglycemia (six of which occurred in non-risk neonates) were identified. The overall incidence of severe hypoglycemia was 1 in 5,827 normal-weight term births, and the incidence in non-risk neonates was 1 in 10 682 normal-weight term births. All of the cases in non-risk neonates were diagnosed as hyperinsulinemic hypoglycemia. CONCLUSIONS This is the first population-based study to have identified the actual incidence of severe pathological neonatal hypoglycemia in non-risk neonates. The incidence was not low compared with those of the newborn screening disorders, justifying the necessity of BG screening even in non-risk neonates.

Abstract
OBJECTIVE To evaluate the efficacy of a strict glycaemic control protocol using a continuous glucose monitoring (CGM) in infants at high risk of dysglycaemia with the aim of reducing the number of dysglycaemic episodes. DESIGN Randomised controlled trial. SETTING Neonatal intensive care unit, Fondazione Policlinico Universitario Agostino Gemelli, IRCCS, Rome. PATIENTS All infants <1500 g fed on parental nutrition (PN) since birth were eligible. A total of 63 infants were eligible and 48 were randomised. INTERVENTION All participants wore a CGM sensor and were randomised in two arms with alarms set at different cut-off values (2.61-10 mmol/L (47-180 mg/dL) vs 3.44-7.78 mmol/L (62-140 mg/dL)), representing the operative threshold requiring modulation of glucose infusion rate according to an innovative protocol. MAIN OUTCOME MEASURES The primary outcome was the number of severe dysglycaemic episodes (<2.61 mmol/L (47 mg/dL) or >10 mmol/L (180 mg/dL)) in the intervention group versus the control group, during the monitoring time. RESULTS We enrolled 47 infants, with similar characteristics between the two arms. The number of dysglycaemic episodes and of infants with at least one episode of dysglycaemia was significantly lower in the intervention group (strict group): respectively, 1 (IQR 0-2) vs 3 (IQR 1-7); (p=0.005) and 12 (52%) vs 20 (83%); p=0.047. Infants managed using the strict protocol had a higher probability of having normal glycaemic values: relative risk 2.87 (95% CI 1.1 to 7.3). They spent more time in euglycaemia: 100% (IQR 97-100) vs 98% (IQR 94-99), p=0.036. The number needed to treat to avoid dysglycaemia episodes is 3.2 (95% CI 1.8 to 16.6). CONCLUSION We provide evidence that CGM, combined with a protocol for adjusting glucose infusion, can effectively reduce the episodes of dysglycaemia and increase the percentage of time spent in euglycaemia in very low birthweight infants receiving PN in the first week of life.

Abstract
Background There is a lack of clarity of what constitutes the starting point of a clinical pathway for infants at-risk of hypoglycaemia. Glucose-centric pathways (GCP) identify low glucose in the first 2 hours of life that may not represent clinical hypoglycaemia and can lead to inappropriate glucose management with infusions and medications. Objective To study the impact of a feed-centric pathway (FCP) on the number of admissions for hypoglycaemia to level 2 special care nursery (SCN) and the need for parenteral glucose/medications, compared to GCP. Methods This project was conducted over 2 years, before and after switching from a GCP to FCP in our institution. FCP involves skin-to-skin care, early breast feeding, checking glucose at 2 hours and use of buccal glucose. The primary outcome was the number of SCN admissions for hypoglycaemia. Secondary outcomes include the number of infants needing intravenous glucose, medications and length of SCN stay. Results Of 23 786 live births, 4438 newborns were screened. We screened more infants at-risk for hypoglycaemia using the FCP (GCP:1462/11969, 12.2% vs FCP:2976/11817, 25.1%) but significantly reduced SCN admissions (GCP:246/1462, 16.8% vs FCP:102/2976, 3.4%; p<0.0001). Fewer but proportionally more FCP newborns required intravenous glucose (GCP: 136/246, 55% vs FCP: 88/102, 86%; p=0.000). Compared with GCP, FCP reduced the total duration of stay in SCN by 104 days per annum, reducing the cost of care. However, the mean length of SCN stay for FCP was higher (GCP:2.43 days vs FCP:3.49 days; p=0.001). There were no readmissions for neonatal hypoglycaemia to our institution. Conclusion The use of FCP safely reduced SCN admissions, averted avoidable escalation of care and helped identify infants who genuinely required intravenous glucose and SCN care, allowing more efficient utilisation of healthcare resources.

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.

Management of asymptomatic hypoglycemia with 40% oral dextrose gel in near term at-risk infants to reduce intensive care need and promote breastfeeding. Ital J Pediatr 2021; 47:201. [PMID: 34627324 PMCID: PMC8500822 DOI: 10.1186/s13052-021-01149-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Accepted: 09/13/2021] [Indexed: 11/23/2022] Open
Abstract
Background Neonatal hypoglycemia is a common disorder especially in at-risk infants and it can be associated with poor long-term neurological outcomes. Several therapeutic interventions are suggested, from the implementation of breastfeeding to the glucose intravenous administration. Oral dextrose gel massaged into the infant’s inner cheek is a recent treatment option of asymptomatic hypoglycemia, after which oral feeding is encouraged. This approach seems to reduce the admission of infants to neonatal intensive care unit (NICU) so favouring maternal bonding and breastfeeding success at discharge. Methods In our ward, we prospectively compared a group of near-term neonates, (Gr2, n = 308) at risk for hypoglycemia, treated with an innovative protocol based on the addition of 40% oral dextrose gel (Destrogel, Orsana®,Italy) administered by massaging gums and cheek with historical matching newborns (Gr1, n = 389) treated with a formerly used protocol, as control group. The primary outcome was occurrence of NICU admission and the requirement of intravenous glucose administration; while discharge with full breastfeeding was the secondary outcome. Results In Gr1, 39/389 (10%) infants presented with asymptomatic hypoglycemia, 19/39 were transferred to the NICU, and 14/39 required intravenous glucose treatment. In Gr2, among the 30/308 infants with asymptomatic hypoglycemia managed according to the new protocol, 3/30 were transferred to the NICU and received intravenous glucose infusion. The mean duration of hospitalization respectively was 6.43 (± 6.36) and 3.73 ± 1.53 days (p < 0.001). At discharge, 7.7% of the infants in Gr1 and 30% of the infants in Gr2 were exclusively breastfed (p = 0.02). Considering Gr1 vs Gr2, the number of patients that were transferred to NICU was 19 (48.7%) vs 3 (10%) (p = 0.001) and the number of infants that needed intravenous glucose infusion was 14 (35.9%) vs 3 (10%) (p = 0.01), respectively. Conclusions In our population of near term infants, the introduction of 40% oral dextrose gel to the protocol, helped in the safe management of asymptomatic hypoglycemia and, at the same time, implemented breastfeeding.

Abstract
Insufficient milk intake in breastfed neonates is common, frequently missed, and causes preventable hospitalizations for jaundice/hyperbilirubinemia, hypernatremia/dehydration, and hypoglycemia - accounting for most U.S. neonatal readmissions. These and other consequences of neonatal starvation and deprivation may substantially contribute to fully preventable morbidity and mortality in previously healthy neonates worldwide. Previous advanced civilizations recognized this problem of breastfeeding insufficiencies and had an infrastructure to solve it: Wetnursing, shared nursing, and prelacteal feeding traditions used to be well-organized and widespread. Modern societies accidentally destroyed that infrastructure. Then, modern reformers missing a few generations of direct knowledge transmission about safe breastfeeding invented a new, historically anomalous conception of breastfeeding defined in terms of exclusivity. As that new intervention has become increasingly widespread, so too have researchers widely reported associated possible harms of the longer neonatal starvation/deprivation and later infant under-nutrition periods that it creates when breastfeeding is insufficient. Early insufficient nutrition/hydration has possible long-term effects including neurodevelopmental consequences such as attention deficit hyperactivity disorder, autism, cerebral palsy, cognitive and developmental delay, epilepsy, hearing impairment, kernicterus, language disorder, mood disorders, lower IQ, and specific learning disorder. Current early infant feeding guidelines conflict with the available evidence. Recent reform efforts have tended to focus on using more technology and measurement to harm fewer neonates instead of proposing the indicated paradigm shift in early infant feeding to prevent more harm. The scientific evidence is already sufficient to mandate application of the precautionary principle to feed neonates early, adequate, and often milk before mothers' milk comes in and whenever signs of hunger persist, mitigating possible risks including death or disability. In most contexts, the formula is the best supplementary milk for infants at risk from breastfeeding insufficiencies. National-level reviews of scientific evidence, health policy, and research methods and ethics are needed to initiate the early infant feeding paradigm shift that the data already support. Policy experiments and related legislative initiatives might also contribute to the shift, as insurers might decline or be required by law to decline reimbursing hospitals for costs of this type of preventable hospitalization, which otherwise generates profit.

Abstract
Adequate nutrition and glycemic homeostasis are increasingly recognized as potentially neuroprotective for the developing brain. In the context of hypoxia-ischemia, evidence is scarce regarding optimal nutritional support and administration route, as well as the short- and long-term consequences of such interventions. In this review, we summarize current knowledge on disturbances of brain metabolism of glucose and substrates by hypoxia-ischemia, and compound effects of these mechanisms on brain injury characterized by specific patterns on EEG and MRI. Risks and benefits of nutrition delivery via parenteral or enteral routes are examined. Nutrition could mitigate adverse neurodevelopmental outcomes, and the impact of nutritional strategies and specific nutritional interventions are reviewed. Limited literature highlights the need for further studies to understand the changes in energy metabolism during and after hypoxic-ischemic injury, to optimize nutritional regimens and glucose management, and to inform the neuroprotective role of nutrition.

Abstract
This review provides an update on neonatal hypoglycemia in the term infant, including discussion of glucose metabolism, definitions of hypoglycemia, identification of infants commonly at risk, and the screening, treatment, and potential neurologic outcomes of postnatal hypoglycemia. Neonatal hypoglycemia is a common metabolic condition that continues to plague clinicians because there is no clear relationship between low glucose concentrations or their duration that determines adverse neurologic outcomes. However, severely low, prolonged, recurrent low glucose concentrations in infants who also have marked symptoms such as seizures, flaccid hypotonia with apnea, and coma clearly are associated with permanent brain damage. Early identification of at-risk infants, early and continued breastfeeding augmented with oral dextrose gel, monitoring prefeed glucose concentrations, treating symptomatic infants who have very low and recurrent low glucose concentrations, and identifying and aggressively managing infants with persistent hyperinsulinemia and metabolic defects may help prevent neuronal injury.

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..
