Abstract
Neonatal hypoglycemia is a major source of concern for pediatricians since it has commonly been related to poor neurodevelopmental outcomes. Diagnosis is challenging, considering the different operational thresholds provided by each guideline. Screening of infants at risk plays a crucial role, considering that most hypoglycemic infants show no clinical signs. New opportunities for prevention and treatment are provided by the use of oral dextrose gel. Continuous glucose monitoring systems could be a feasible tool in the next future. Furthermore, there is still limited evidence to underpin the current clinical practice of administering, in case of hypoglycemia, an intravenous "mini-bolus" of 10% dextrose before starting a continuous dextrose infusion. This brief review provides an overview of the latest advances in this field and neurodevelopmental outcomes according to different approaches. Conclusion: To adequately define if a more permissive approach is risk-free for neurodevelopmental outcomes, more research on continuous glucose monitoring and long-term follow-up is still needed. What is Known: • Neonatal hypoglycemia (NH) is a well-known cause of brain injury that could be prevented to avoid neurodevelopmental impairment. • Diagnosis is challenging, considering the different suggested operational thresholds for NH (<36, <40, <45, <47 or <50 mg/dl). What is New: • A 36 mg/dl threshold seems to be not associated with a worse psychomotor development at 18 months of life when compared to the "traditional" threshold (47 mg/dl). • Further studies on long-term neurodevelopmental outcomes are required before suggesting a more permissive management of NH.

Abstract
Background Worldwide, the immigration problem has been increasing due to conflicts. In recent years, Turkey accepted more than 3.8 million refugees from many countries, principally Syria. Aims In this study, we aimed to evaluate the prenatal features and neonatal outcomes of refugees and Turkish controls hospitalized in a tertiary neonatal intensive care unit in Turkey. Materials and methods This retrospective case-control study included comparative data related to populations based on whether they were refugees or not. Their perinatal and neonatal "outcomes" were compared. Results Among the 254 analyzed neonates, 127 were born to refugee mothers, and 127 controls were born to non-refugee Turkish mothers. The refugee rate in our hospitalized neonates was nine, a young mother's age (p=0.010) with a higher rate of adolescent pregnancies at OR 2.78 (95% CI 0.96-8.05) (p=0.032), and consanguineous marriage at OR 0.57 (95% CI 0.32-1.02) (p=0.031) in comparison to non-refugees. The incidence of ABO incompatibility-related hemolytic jaundice (p=0.013) was higher in the refugees. The rate of formula feeding in the first month of life was significantly higher at OR 0.49 (95% CI 0.25-0.92) (p=0.027) in neonates born to refugee mothers. Despite lower perinatal care rates in refugees at OR 7.23 (95%CI 4.12-12.69) (<0.001), preterm morbidities did not differ between refugees and non-refugee preterm infants ≤32 gestational age (p>0.05). Conclusion The importance of breast milk must be strongly encouraged to initiate and promote exclusive breastfeeding for the infants of refugees. Race is still an important risk factor for ABO incompatibility-related hemolytic jaundice. Providing high-quality healthcare is sufficient to prevent worse outcomes in refugee neonates.

Front Pediatr 2023; 11:1072663. [PMID: 37425273 PMCID: PMC10323750 DOI: 10.3389/fped.2023.1072663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 06/02/2023] [Indexed: 07/11/2023] Open
Abstract
Hypoxic-ischemic encephalopathy (HIE) secondary to perinatal asphyxia occurs when the brain does not receive enough oxygen and blood. A surrogate marker for "intact survival" is necessary for the successful management of HIE. The severity of HIE can be classified based on clinical presentation, including the presence of seizures, using a clinical classification scale called Sarnat staging; however, Sarnat staging is subjective, and the score changes over time. Furthermore, seizures are difficult to detect clinically and are associated with a poor prognosis. Therefore, a tool for continuous monitoring on the cot side is necessary, for example, an electroencephalogram (EEG) that noninvasively measures the electrical activity of the brain from the scalp. Then, multimodal brain imaging, when combined with functional near-infrared spectroscopy (fNIRS), can capture the neurovascular coupling (NVC) status. In this study, we first tested the feasibility of a low-cost EEG-fNIRS imaging system to differentiate between normal, hypoxic, and ictal states in a perinatal ovine hypoxia model. Here, the objective was to evaluate a portable cot-side device and perform autoregressive with extra input (ARX) modeling to capture the perinatal ovine brain states during a simulated HIE injury. So, ARX parameters were tested with a linear classifier using a single differential channel EEG, with varying states of tissue oxygenation detected using fNIRS, to label simulated HIE states in the ovine model. Then, we showed the technical feasibility of the low-cost EEG-fNIRS device and ARX modeling with support vector machine classification for a human HIE case series with and without sepsis. The classifier trained with the ovine hypoxia data labeled ten severe HIE human cases (with and without sepsis) as the "hypoxia" group and the four moderate HIE human cases as the "control" group. Furthermore, we showed the feasibility of experimental modal analysis (EMA) based on the ARX model to investigate the NVC dynamics using EEG-fNIRS joint-imaging data that differentiated six severe HIE human cases without sepsis from four severe HIE human cases with sepsis. In conclusion, our study showed the technical feasibility of EEG-fNIRS imaging, ARX modeling of NVC for HIE classification, and EMA that may provide a biomarker of sepsis effects on the NVC in HIE.

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
Neonatal hipoglisemi yenidoğan döneminde sık görülen, yaşamın ilerleyen dönemlerini de etkileyen bir sağlık sorunudur. Hipoglisemi akut ve kronik komplikasyonlara neden olarak yenidoğan bebeğin büyümesi ve gelişmesinde kalıcı ve geri dönüşümsüz nörolojik sorunlara yol açabilmektedir. Hipoglisemiyi saptamak için en duyarlı test halen plazma glukozu ile ölçümü olsa da, yıllardır kullanılan geleneksel glukoz ölçüm yöntemleri ile birlikte son yıllarda noninvaziv glukoz ölçüm yöntemlerindeki gelişmeler ile riskli bebeklerde hipogliseminin tanı ve tedavisinde bu teknolojik ölçüm yöntemleri yaygın kullanılmaya başlamıştır. Glukometre, kan gazı analizatörleri, laboratuvarda enzimatik ölçüm geleneksel ölçüm yöntemleri iken, sürekli glukoz ölçüm sistemleri yeni nesil glukoz ölçümünde yer almaya başlayan yeni bir tekniktir. Hipoglisemi gelişimini engellemek için koruyucu önlemler alırken erken dönemde anne sütü ile emzirme desteği sağlanmalı ve teşvik edilmelidir. Hangi durumların hipoglisemi için risk oluşturduğu, hangi glukoz eşik değerinde tedavi vermek gerektiği ve son kullanılan yeni nesil glukoz ölçüm yöntemlerinin etkileri ve güncel tedaviler bu derlemede tartışılmıştır. Riskli bebeklerde kan şekeri ölçümleri ve klinik bulguların gözlenmesi yanında hipoglisemide ayırıcı tanı yapılarak tedavinin yönetilmesi de prognozda önemli bir yer tutar.

Abstract
OBJECTIVE The aim of this study was to determine the effect of breastfeeding and intensive breast milk nutritional support program (IBNSP) on hospitalization rates for hyperbilirubinemia in normal term newborns. METHODS This study's sample consisted of 68 newborn infants (experimental group: 34; control group: 34) born at a university hospital from October 2020 to April 2021. Five steps of breastfeeding and IBNSP were administered to the experimental group for the first 48 h after birth. This program starts at the postpartum first hour and continues until the 48th hour. It includes face-to-face training, practical support on breastfeeding, and one-to-one demonstration and practice methods. The control group received the standard care recommended by the World Health Organization. Both groups' bilirubin levels were measured 24 and 72 h after birth. Participants in both groups were hospitalized for risky (according to bilirubin values) situations. The groups' bilirubin levels and hospitalization rates for hyperbilirubinemia were compared. RESULTS There was no statistically significant difference between the experimental (5.19 ± 1.27) and the control (5.83 ± 1.52) groups' bilirubin levels at 24 h after birth, (t = -1.881, p = 0.064); however, the control group infants (12.03 ± 3.67 mg/dl) had higher bilirubin levels than the infants in the experimental group 72 h after birth (9.55 ± 2.82 mg/dl) (t = -3.122, p = 0.003). The experimental group's hospitalization rate for hyperbilirubinemia (n: 1, 2.9%) was lower than the control group's rate (n: 8, 23.5%), and this difference was statistically significant (X2 = 6.275, p = 0.014). CONCLUSIONS Breastfeeding and IBNSP effectively prevent hospitalization for hyperbilirubinemia and reduce newborns' bilirubin levels.

Neonatal Problems and Infancy Growth of Term SGA Infants: Does "SGA" Definition Need to Be Re-evaluated? Front Pediatr 2021; 9:660111.

Abstract
Introduction: The exact definition of small-for-gestational-age (SGA) infant is still controversial among clinicians. In this study, we aimed to understand which definition is better in terms of establishing both early postnatal problems and growth. In this way, we compared early neonatal problems and infancy growth of term infants with birth weight (BW) < -2 SDS and with BW between 10th percentile (-1.28 SDS) and -2 SDS. Methods: A single center retrospective cohort study was conducted. Preterm infants, multiple gestations and newborns with any congenital anomalies were excluded from the study. Study group was defined as Group 1 (n = 37), infants BW < -2.00 SDS; Group 2 (n = 129), between -1.28 and -2.00 SDS; and Group 3 (n = 137), randomly selected newborns with optimal-for-gestational-age (BW between -0.67 and +0.67 SDS) as a control group. Results: The incidence of severe hypoglycemia was highest in Group 1 (%10.8) and Group 2 and 3 had similar rates of severe hypoglycemia (0.8 and 0.7%, respectively). The incidence of polycythemia was 5.4% in Group 1 and was significantly higher than Group 3 (0.0%) while it was 2.3% in Group 2. Short stature (length < -2 SDS) ratio at the age of 1 and 2 years were similar in each group. Overweight/obesity ratio at the age of 1 were 9.5, 20.8 and 16.7% in each group, respectively (p = 0.509). Conclusion: This study was planned as a pilot study to determine potential differences in the problems of hypoglycemia, polycythemia, and growth according to the differences in definition. Short term disturbances such as hypoglycemia and polycythemia are found to be higher in infants with a BW SDS below -2. From this point of view, of course, it will not be possible to change the routine applications immediately, however this study will be an initiative for discussions by making long-term studies.
