Neonatal hypoglycaemia.

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.

Improving Golden Hour Care Coordination: Using Defined Roles to Improve Nurse Confidence and Care Coordination of Neonates Following Admission.

STUDY AIM: To investigate whether use of admission lanyards improves nurse confidence, care coordination, and infant health outcomes during neonatal emergency admissions. METHODS: Admission lanyards that defined team roles, tasks, and responsibilities were evaluated in a mixed-methods, historically controlled, and nonrandomized intervention study. Methods included (i) 81 pre- and postintervention surveys to explore nurse confidence, (ii) 8 postintervention semistructured interviews to elicit nurse perceptions of care coordination and nurse confidence, and (iii) a quantitative comparison of infant care coordination and health outcomes for 71 infant admissions before and 72 during the intervention. RESULTS: Nurse participants reported that using lanyards during neonatal admissions improved clarity of roles and responsibilities, communication, and task delegation, contributing to better admission flow, team leadership, accountability, and improved nurse confidence. Care coordination outcomes showed significantly improved time to stabilization for intervention infants. Radiographies for line placement were performed 14.4 minutes faster, and infants commenced intravenous nutrition 27.7 minutes faster from time of admission. Infant health outcomes remained similar between groups. CONCLUSION: Admission lanyards were associated with improved nurse confidence and care coordination during neonatal emergency admissions, significantly reducing time to stabilization for infants, shifting outcomes closer to the Golden Hour.

Family presence during resuscitation in paediatric and neonatal cardiac arrest: A systematic review.

CONTEXT: Parent/family presence at pediatric resuscitations has been slow to become consistent practice in hospital settings and has not been universally implemented. A systematic review of the literature on family presence during pediatric and neonatal resuscitation has not been previously conducted. OBJECTIVE: To conduct a systematic review of the published evidence related to family presence during pediatric and neonatal resuscitation. DATA SOURCES: Six major bibliographic databases was undertaken with defined search terms and including literature up to June 14, 2020. STUDY SELECTION: 3200 titles were retrieved in the initial search; 36 ultimately included for review. DATA EXTRACTION: Data was double extracted independently by two reviewers and confirmed with the review team. All eligible studies were either survey or interview-based and as such we turned to narrative systematic review methodology. RESULTS: The authors identified two key sets of findings: first, parents/family members want to be offered the option to be present for their child's resuscitation. Secondly, health care provider attitudes varied widely (ranging from 15% to >85%), however, support for family presence increased with previous experience and level of seniority. LIMITATIONS: English language only; lack of randomized control trials; quality of the publications. CONCLUSIONS: Parents wish to be offered the opportunity to be present but opinions and perspectives on the family presence vary greatly among health care providers. This topic urgently needs high quality, comparative research to measure the actual impact of family presence on patient, family and staff outcomes. PROSPERO REGISTRATION NUMBER: CRD42020140363.

Utility of published skinfold thickness equations for prediction of body composition in very young New Zealand children.

Measurement of body composition is increasingly important in research and clinical settings but is difficult in very young children. Bioelectrical impedance analysis (BIA) and air displacement plethysmography (ADP) are well-established but require specialist equipment so are not always feasible. Our aim was to determine if anthropometry and skinfold thickness measurements can be used as a substitute for BIA or ADP for assessing body composition in very young New Zealand children. We used three multi-ethnic cohorts: 217 children at a mean age of 24·2 months with skinfold and BIA measurements; seventy-nine infants at a mean age of 20·9 weeks and seventy-three infants at a mean age of 16·2 weeks, both with skinfold and ADP measurements. We used Bland-Altman plots to compare fat and fat-free mass calculated using all potentially relevant equations with measurements using BIA or ADP. We also calculated the proportion of children in the same tertile for measured fat or fat-free mass and tertiles (i) calculated using each equation, (ii) each absolute skinfold, and (iii) sum of skinfold thicknesses. We found that even for the best equation for each cohort, the 95 % limits of agreement with standard measures were wide (25-200 % of the mean) and the proportion of children whose standard measures fell in the same tertile as the skinfold estimates was ≤69 %. We conclude that none of the available published skinfold thickness equations provides good prediction of body composition in multi-ethnic cohorts of very young New Zealand children with different birth history and growth patterns.

Relationship between BMI and adiposity among different ethnic groups in 2-year-old New Zealand children.

Age- and sex-based BMI cut-offs are used to define overweight and obesity, but the relationship between BMI and body composition has not been very well studied in children or compared between children of different ethnic groups. Body size and composition in childhood are also influenced by size at birth. Our aim was to compare body size and composition at 2 years in children with different ethnicity and size at birth. We prospectively followed a multi-ethnic cohort of 300 children born with risk factors for neonatal hypoglycaemia (infants of diabetics, large or small at birth or late preterm) to 2 years corrected age. Complete data on weight, height and head circumference and body composition using bioelectrical impedance 24±1 months corrected age were available in 209 children. At birth, compared with European children, Chinese, Indian and other ethnicity children were lighter, and Indian children had smaller head circumferences, but birth lengths were similar in all ethnic groups. At 2 years, Pacific children were heavier and had higher BMI z scores, and Indian children had smaller head circumferences and lower BMI z scores than those from other ethnic groups. However, fat mass and fat-free mass indices were similar in all groups. At median BMI, fat mass:fat-free mass ratio was 23 % lower in Pacific than in Indian children (0·22 v. 0·27, P=0·03). BMI is not a good indicator of adiposity in this multi-ethnic cohort of 2-year-old New Zealand children.

Neonatal Cardiovascular Function after Antenatal Sildenafil for Severe, Early-Onset Intrauterine Growth Restriction: A Substudy of the STRIDER-NZAus Randomized Placebo-Controlled Trial.

We evaluated the effect of antenatal sildenafil on neonatal cardiovascular function in a subgroup of 27 infants of mothers participating in the STRIDER-NZAus randomized controlled trial. In this small study, we found no association between antenatal sildenafil and neonatal cardiac dysfunction including no pulmonary hypertension in exposed or unexposed infants.

Community-based screening to detect school readiness problems in very preterm children.

AIM: Very preterm (VPT) children (≤32 weeks) have school readiness difficulties across multiple domains, but routine follow-up is often limited. We assessed the performance of VPT children on the Before School Check (B4SC), a community-based screening programme of school readiness at 4 years of age. METHODS: VPT children discharged from Wellington and Auckland Neonatal Intensive Care Units (2005-2009) were compared to a national control cohort born during the same period. Outcome measures included Parental Evaluation of Developmental Status (PEDS), parent and teacher versions of the Strengths and Difficulties Questionnaire (SDQ-P and SDQ-T) and vision and hearing screening, and were related to perinatal and demographic characteristics obtained from the Australia and New Zealand Neonatal Network database. RESULTS: Of 1105 VPT children, 920 were matched to the B4SC database, of whom 814 (88%) had one or more B4SC screening outcomes recorded. Compared with controls, VPT children were more likely to have abnormal PEDS (odds ratio (OR) = 1.79, 1.53-2.10), SDQ-P (OR = 1.82, 1.49-2.23), SDQ-T (OR = 1.51, 1.10-2.06), vision (OR = 2.00, 1.54-2.60) and hearing (OR = 1.95, 1.65-2.31) screen outcomes. While VPT children with an abnormal screen were more likely to be referred for further assessment, only 34%, 22%, 94% and 51% with abnormal PEDS, SDQ or vision and hearing screen, respectively, had evidence of appropriate referral. School readiness difficulties were significantly associated with birthweight z-score ≤ -1, vaginal delivery, significant cranial ultrasound abnormalities, younger maternal age, higher deprivation neighbourhood and ventilation ≥72 h. CONCLUSION: Community-based screening may be useful for identifying VPT children with school readiness difficulties, but low referral rates may limit the effectiveness of such programmes.

Understanding the associations and significance of fetal movements in overweight or obese pregnant women: a systematic review.

INTRODUCTION: Presentation with decreased fetal movement (DFM) is associated with fetal growth restriction and stillbirth. Some studies report that DFM is frequent among overweight or obese mothers. We aimed to determine the significance and associations of fetal movements in women of increased body size. MATERIAL AND METHODS: This systematic review was conducted in accordance with the PRISMA statement and the protocol was registered with PROSPERO (CRD42016046352). Major databases were explored from inception to September 2017, using a predefined search strategy. We restricted inclusion to studies published in English and considered studies of any design that compared fetal movements in women of increased and normal body size. Two authors independently extracted data and assessed quality. RESULTS: We included 23 publications from 19 observational studies; data were extracted from 10 studies. Increased maternal body size was not associated with altered perception of fetal movement (four studies, 95 women, very low-quality evidence), but was associated with increased presentation for DFM (two cohort studies, 20 588 women, OR 1.56, 95% CI 1.27-1.92: three case-control studies, 3445 women, OR 1.32, 95% CI 1.12-1.54; low-quality evidence). Among women with DFM, increased maternal body size was associated with increased risk of stillbirth and fetal growth restriction (one study, 2168 women, very low-quality evidence). CONCLUSIONS: This systematic review identified limited evidence that women with increased body size are more likely to present with DFM but do not have impaired perception of fetal movements. In women with DFM, increased body size is associated with worse pregnancy outcome, including stillbirth.
