Introduction: We sought to investigate if the availability of cerebral fuels soon after birth in healthy term babies was associated with developmental progress at 3 years of age.

Methods: Healthy term babies had plasma glucose, lactate, and beta-hydroxybutyrate concentrations measured over the first 5 days. At 3 years, parents completed Ages and Stages (ASQ-3) questionnaires between December 2018 and August 2022.

Objective: The Glucose in Well Babies (GLOW) Study showed that there are two phases of low glucose concentrations in healthy newborn infants: an initial phase in which plasma concentrations of ketones are low; and a second phase in which low glucose concentrations are accompanied by elevated concentrations of ketones. The implications of these two phases for the brain differ depending on whether ketones are available as alternative substrate for brain metabolism. The purpose of this study was to estimate the duration of these two phases of neonatal low glucose concentrations in 66 healthy breastfed newborns from the GLOW Study during the first 5 days of life.

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.

Background: The World Health Organization recommends breastfeeding be commenced as soon as possible after birth. Amongst other benefits, early feeding is expected to support the metabolic transition after birth, but effects on blood glucose concentrations are controversial. We sought to describe the changes in interstitial glucose concentrations after feedings over the first five postnatal days.

Article Synopsis
  • Neonatal hypoglycemia, which occurs when a newborn's blood sugar drops too low, may lead to concerns about Executive and visual-motor skills later in life, specifically regarding educational outcomes.
  • A study involving 614 infants at risk of hypoglycemia showed that those who experienced hypoglycemic episodes were evaluated at 9-10 years old to determine their academic performance.
  • Results indicated that there was no significant difference in educational achievement between children who experienced neonatal hypoglycemia and those who did not, suggesting that the impact of early hypoglycemia on later learning might not be as pronounced as previously thought.

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.

Empathy is positively related to healthcare workers and patients' wellbeing. There is, however, limited research on the effects of empathy education delivered in acute clinical settings and its impact on healthcare consumers. This research tests the feasibility and the potential efficacy outcomes of an immersive education programme developed by the research team in collaboration with clinical partners and a multidisciplinary advisory group.

Neonatal hypoglycaemia is associated with adverse development, particularly visual-motor and executive function impairment, in childhood. As neonatal hypoglycaemia is common and frequently asymptomatic in at-risk babies-ie, those born preterm, small or large for gestational age, or to mothers with diabetes, it is recommended that these babies are screened for hypoglycaemia in the first 1-2 days after birth with frequent blood glucose measurements. Neonatal hypoglycaemia can be prevented and treated with buccal dextrose gel, and it is also common to treat babies with hypoglycaemia with infant formula and intravenous dextrose.

Objectives: To determine postnatal changes in plasma and interstitial glucose concentrations of healthy infants receiving current recommended care and to compare the incidence of low concentrations with recommended thresholds for treatment of at-risk infants.

Study Design: A prospective masked observational study in Hamilton, New Zealand. Healthy, term, appropriately grown singletons had continuous glucose monitoring and repeated heel-prick plasma glucose measurements (4 in the first 24 hours then twice daily using the glucose oxidase method) from birth to 120 hours.

Objective: There is a paucity of data about normal blood metabolite concentrations in healthy babies, in part because of a reluctance to undertake non-therapeutic invasive testing in newborns. The Glucose in Well Babies study (GLOW) sought to describe blood glucose, lactate and beta-hydroxybutyrate concentrations in healthy term babies over the first 5 postnatal days. We also sought to understand both parents' experience of participation in this invasive non-therapeutic study.

Higher and unstable glucose concentrations in the first 48 hours in neonates at risk of hypoglycaemia have been associated with neurosensory impairment. It is unclear what defines and contributes to instability. This was a prospective study of term and late preterm babies (N = 139) born at risk of neonatal hypoglycaemia who had interstitial glucose (IG) monitoring and ≥1 hypoglycaemic episode <48 hours after birth (blood glucose concentration <2.

Background: Feeding is often used for the initial treatment of hypoglycaemia, but it is not known if pre-feed alertness and observed quality of breastfeeding are related to the subsequent change in blood glucose concentration.

Objective: We sought to determine if assessment of pre-feed alertness and the observed quality of the breastfeed were related to the subsequent change in blood glucose concentration in hypoglycaemic babies.

Methods: Babies were ≥35 weeks, ≤48 h old, identified as being at-risk for hypoglycaemia (infants of diabetic mothers, small [< 2,500 g or < 10th centile] or large [birthweight > 4,500 g or > 90th centile] birthweight) and hypoglycaemic (< 2.

Objective: Babies may use alternative cerebral fuels including ketones when blood glucose concentrations are low, but laboratory ketone measurements are slow and expensive. Point-of-care measurement of ketone concentrations, if sufficiently accurate, may provide useful information for clinical care.

Patients And Design: Eligible babies were 35-42 weeks' gestation, ≤10 days old and admitted to the newborn intensive care unit.

Continuous glucose monitoring (CGM) is well established in the management of diabetes mellitus, but its role in neonatal glycaemic control is less clear. CGM has provided important insights about neonatal glucose metabolism, and there is increasing interest in its clinical use, particularly in preterm neonates and in those in whom glucose control is difficult. Neonatal glucose instability, including hypoglycaemia and hyperglycaemia, has been associated with poorer neurodevelopment, and CGM offers the possibility of adjusting treatment in real time to account for individual metabolic requirements while reducing the number of blood tests required, potentially improving long-term outcomes.
