Persistent and symptomatic periodic breathing beyond the neonatal period in full-term infants: A case series.

INTRODUCTION: Periodic breathing (PB) is considered physiological in the neonatal period and usually disappears in the first months of life. There are few data available on persistent PB after the neonatal period. The objective of this study was to characterize infants born at term with persistent PB after the age of 1 month through polysomnography (PSG) performed during symptoms. METHODS: This retrospective case series included infants born at term between 2012 and 2021, without an underlying disease, who presented with symptoms of persistent PB during a PSG. Persistent PB was defined as more than 1 % of total sleep time (TST) of PB after 1 month of life, and PB was defined as a succession of at least three episodes of central apnea lasting more than 3 s and separated by less than 20 s of normal breathing. RESULTS: A total of 10 infants born at term were included. They underwent PSG for brief resolved unexplained events, desaturation, pauses in breathing, cyanosis, and/or signs of respiratory distress. The percentage of TST spent with PB was 18.1 % before 3 months of age (n = 7), and 4.7 % between 3 and 6 months of age (n = 10). During the first PSG, ≥3 % of desaturation events were observed in 77-100 % of the PB episodes. At the first PSG, nine of the 10 infants had an obstructive apnea-hypopnea index of >10/h and five of 10 infants had a central apnea index of >5/h. Gastroesophageal reflux (GER) was suspected in eight infants. All infants showed improvement in the initial symptoms during the first year of life. CONCLUSION: This study presents cases of persistent and symptomatic PB after 1 month of life in infants born at term. The interesting finding was the presence of obstructive sleep apnea syndrome and/or central apnea syndrome in the majority of children, along with GER.

Antibiotic use in infants at risk of early-onset sepsis: results from a unicentric retrospective cohort study.

BACKGROUND: Antibiotic use for early-onset sepsis represents a high percentage of antibiotic consumption in the neonatal setting. Measures to assess infants at risk of early-onset sepsis are needed to optimize antibiotic use. Our primary objective was to assess the impact of a departmental guideline on antibiotic use among term infants with suspected EOS not confirmed, in our neonatal unit. METHODS: Retrospective cohort study, to compare antibiotic use in term infants during a baseline period of January to December 2018, and a postintervention period from October 2019, to September 2020, respectively. The primary outcome was antibiotic use measured by days of therapy, the antibiotic spectrum index, the antibiotic use rate, and the length of therapy. RESULTS: We included 71 infants in the baseline period and 66 infants in the postintervention period. Compared to those in the baseline period, there was a significant reduction in overall antibiotic measures in the postintervention period, (P < 0.001). The total days of therapy/1000 patient-days decreased from 63/1000 patient-days during the baseline period to 25.8/1000 patient-days in the postintervention period, representing a relative reduction of 59%. The antibiotic use rate decreased by more than half of the infants, from 3.2% during the baseline period to 1.3% in the postintervention period. CONCLUSIONS: The use of a departmental guideline to assess infants at risk of early-onset sepsis based on their clinical condition and prompt discontinuation of antibiotics, is a simple and low-cost measure that contributed to an important decrease in antibiotic use.

Preterm Birth Alters the Regional Development and Structural Covariance of Cerebellum at Term-Equivalent Age.

Preterm birth is associated with increased risk for a spectrum of neurodevelopmental disabilities. The cerebellum is implicated in a wide range of cognitive functions extending beyond sensorimotor control and plays an increasingly recognized role in brain development. Morphometric studies based on volume analyses have revealed impaired cerebellar development in preterm infants. However, the structural covariance between the cerebellum and cerebral cortex has not been studied during the neonatal period, and the extent to which structural covariance is affected by preterm birth remains unknown. In this study, using the structural MR images of 52 preterm infants scanned at term-equivalent age and 312 full-term controls from the Developing Human Connectome Project, we compared volumetric growth, local cerebellum shape development and cerebello-cerebral structural covariance between the two groups. We found that although there was no significant difference in the overall volume measurements between preterm and full-term infants, the shape measurements were different. Compared with the control infants, preterm infants had significantly larger thickness in the vermis and lower thickness in the lateral portions of the bilateral cerebral hemispheres. The structural covariance between the cerebellum and frontal and parietal lobes was significantly greater in preterm infants than in full-term controls. The findings in this study suggested that cerebellar development and cerebello-cerebral structural covariance may be affected by premature birth.

Characteristics of intestinal microbiota in preterm infants and the effects of probiotic supplementation on the microbiota.

Objective: In this study, we investigated the characteristics of the intestinal microbiota of preterm infants, and then analyzed the effects of probiotics supplementation on intestinal microbiota in preterm infants. Methods: This study enrolled 64 infants born between 26 and 32 weeks gestational age (GA) and 22 full-term infants. 34 premature infants received oral probiotic supplementation for 28 days. Stool samples were obtained on the first day (D1) and the 28th day (D28) after birth for each infant. Total bacterial DNA was extracted and sequenced using the Illumina MiSeq Sequencing System, specifically targeting the V3-V4 hyper-variable regions of the 16S rDNA gene. The sequencing results were then used to compare and analyze the composition and diversity index of the intestinal microbiota. Results: There was no significant difference in meconium bacterial colonization rate between premature and full-term infants after birth (p > 0.05). At D1, the relative abundance of Bifidobacterium, Bacteroides, and Lactobacillus in the stool of preterm infants was lower than that of full-term infants, and the relative abundance of Acinetobacter was higher than that of full-term infants. The Shannon index and Chao1 index of intestinal microbiota in preterm infants are lower than those in full-term infants (p < 0.05). Supplementation of probiotics can increase the relative abundance of Enterococcus and Enterobacter, and reduce the relative abundance of Escherichia and Clostridium in premature infants. The Chao1 index of intestinal microbiota decreased in preterm infants after probiotic supplementation (p < 0.05). Conclusion: The characteristics of intestinal microbiota in preterm infants differ from those in full-term infants. Probiotic supplementation can reduce the relative abundance of potential pathogenic bacteria and increase the abundance of beneficial microbiota in premature infants.

The Association between Delayed Gut Microbiota Maturity in Pre-Term Infants and the Feeding Intolerance-A Pilot Study.

This study compared gut (fecal) microbiota profiles between pre-term and full-term infants, assuming that pre-term infants without feeding intolerance would have gut microbiota similar to those of full-term infants. A total of 13 pre-term infants (gestational age < 37 weeks, birthweight ≤ 2500 g) and 10 full-term infants were included. The pre-term infants were assigned to the feeding tolerance (FT) group (n = 7) if their daily intake exceeded 100 mL/kg/day at two weeks after birth, or the feeding intolerance (FI) group (n = 6). Microbial DNA from weekly fecal samples was analyzed. The microbiota profiles of the pre-term infants and full-term infants were significantly different (p = 0.0001), as well as the FT and FI groups (p = 0.0009). The full-term group had more diversity, with higher concentrations of facultative anaerobes such as Bifidobacteriaceae and Lactobacteriaceae. The FT group's gut microbiota matured over four weeks, with higher levels of digestion-related bacteria, while the FI group had more pathogens. In the FI group, a significant difference was observed between the first and second weeks, with no significant differences noted between the first week and the third or fourth weeks. The delay in the development of the pre-term infants' gut microbiota may be associated with the FI.

Differences in the amplitude of low-frequency fluctuations of spontaneous brain activity between preterm and term infants.

Objectives: To date, the majority of research on resting-state functional magnetic resonance imaging (rs-fMRI) in the developing brain has primarily centered on adolescents and adults, leaving a gap in understanding variations in spontaneous brain activity at rest in preterm infants. This study aimed to uncover and comprehend the distinctions in spontaneous brain activity between preterm and term infants, with the goal of establishing a foundation for assessing the condition of preterm infants. Methods: In this study, 14 term infants and 15 preterm infants with equivalent gestational age were carefully chosen from the neonatal unit of Anhui Provincial Children's Hospital. The amplitude of low-frequency fluctuations (ALFF) intensity was assessed using resting-state functional magnetic resonance imaging (rs-fMRI) to examine brain activity in both groups. Subsequently, the differences between the term and preterm infants were statistically analyzed using a two-sample t-test. A p-value of <0.05, corrected for the REST Gaussian Random Fields, was deemed to be statistically significant. Results: In comparison to the term infant group, the preterm infant group exhibited a significant increase in the ALFF value in the left precuneus, left frontal superior orbital gyrus, and left calcarine cortex. Conclusion: Significant variances in spontaneous brain activity have been observed in various regions between term infants and preterm infants of equivalent gestational age. These variations could potentially impact the emotional and cognitive development of preterm infants in the long term.

Comparing the effects of 5-minute premature infant oral motor intervention with 15-minute Fucile treatment in term infants with feeding difficulties: A multi-arm randomised clinical trial.

PURPOSE: The aim of the present study was to investigate whether term infants with feeding difficulties who received either a 5-minute premature infant oral motor intervention (PIOMI) or a 15-minute Fucile treatment had different outcomes, compared to term infants in a nontreatment group. METHOD: Stable term infants (N = 51) born between 37-41 weeks of gestational age with feeding difficulties were randomly assigned into one of two intervention groups and a control group. One intervention group received PIOMI and the other group received Fucile treatment once a day for seven consecutive days; the control group received usual care only. The volume of milk intake, the amount of weight gain, and the length of hospital stay were compared across all groups. RESULT: Findings indicated that the volume of milk intake and weight gain showed significant improvement in all three groups. However, pairwise comparison revealed that infants in the Fucile group had significantly higher volume of milk intake and weight gain compared to infants in both the control and PIOMI groups. Length of hospital stay was not significantly different amongst all groups. CONCLUSION: The effects of Fucile treatment were more considerable than for usual care or PIOMI. This finding raises the possibility that prolonged exercise may facilitate improvement in feeding skills for term infants with feeding difficulties.

Correlation between total deceleration area in CTG records and cord blood pH in pregnancies with IUGR.

PURPOSE: Fetal cardiotocography is the most common method to assess fetal well-being during labor. Nevertheless, its predictive ability for acidemia is limited, both in low-risk and high-risk pregnancies (Nelson et al. in N Engl J Med 334: 613-9, 1996; Rinciples P et al. in Health and Human Development Workshop Report on Electronic Fetal Monitoring : Update on Definitions. no. 2007, 510-515, 2008), especially in high-risk pregnancies, such as those complicated by growth restriction. In this study we aim examine the association between deceleration and acceleration areas and other measure of fetal heart rate in intrapartum fetal monitoring and neonatal arterial cord blood pH in pregnancies complicated by growth restriction. MATERIALS AND METHODS: A retrospective cohort study of 100 deliveries complicated by growth restriction, delivered during 2018, was conducted. Known major fetal anomalies, non-vertex presentation and elective cesarean deliveries were excluded. Total deceleration and acceleration areas were calculated as the sum of the areas within the deceleration and acceleration, respectively. RESULTS: In deliveries complicated by growth restriction, cord blood pH is significantly associated with total deceleration area (p = 0.05) and correlates with cumulative duration of the decelerations (Spearman's rank -0.363, p < 0.05), and total acceleration area (-0.358, p < 0.05). By comparing the cord blood pH in deliveries with a total deceleration area that was above and below the median total deceleration area, we demonstrated a significant difference between the categories. CONCLUSIONS: Cord blood pH significantly correlates with total deceleration area and other fetal monitoring characteristics in neonates with growth restriction. Future studies using real-time, machine-learning based techniques of fetal heart rate monitoring, may provide population specific threshold values that will support bedside clinical decision making and perhaps achieve better outcomes.

The head circumference to chest circumference ratio provided an easy way to detect foetal growth restriction in term infants.

AIM: The head circumference to chest circumference (HC/CC) ratio has been used to identify low birth weight infants in developed countries. This study was conducted to examine whether the ratio could distinguish asymmetrical foetal growth restriction (FGR). METHODS: This retrospective observational study was conducted with 1955 infants (50.5% male) born at term between 2016 and 2020 at Tokyo Metropolitan Toshima Hospital, Japan. RESULTS: We found that 120 (6.1%) had FGR. Their mean birth weight was 3052.1 ± 367.3 g, and their mean gestational age was 39.1 ± 1.1 weeks. Logistic regression analysis showed that the association between the HC/CC ratio and FGR had a regression coefficient of -20.6 (p < 0.000). The linear regression analysis showed that the association between the HC/CC ratio and the birth weight z-score had a regression coefficient of -8.59 (p < 0.000). The coefficient of correlation was -0.33 (p < 0.001). The receiver operating characteristic curve for detecting FGR showed that the area under the curve was 0.75 and the cut-off value was 0.93, with sensitivity of 75.8% and specificity of 60.8%. CONCLUSION: Our study established the associations between HC/CC ratio and FGR and birth weight z-scores and confirmed that the ratio provided an easy way to detect FGR in term-born infants.

Physiologically Based Pharmacokinetic Modeling in Neonates: Current Status and Future Perspectives.

Rational drug use in special populations is a clinical problem that doctors and pharma-cists must consider seriously. Neonates are the most physiologically immature and vulnerable to drug dosing. There is a pronounced difference in the anatomical and physiological profiles be-tween neonates and older people, affecting the absorption, distribution, metabolism, and excretion of drugs in vivo, ultimately leading to changes in drug concentration. Thus, dose adjustments in neonates are necessary to achieve adequate therapeutic concentrations and avoid drug toxicity. Over the past few decades, modeling and simulation techniques, especially physiologically based pharmacokinetic (PBPK) modeling, have been increasingly used in pediatric drug development and clinical therapy. This rigorously designed and verified model can effectively compensate for the deficiencies of clinical trials in neonates, provide a valuable reference for clinical research design, and even replace some clinical trials to predict drug plasma concentrations in newborns. This review introduces previous findings regarding age-dependent physiological changes and pathological factors affecting neonatal pharmacokinetics, along with their research means. The application of PBPK modeling in neonatal pharmacokinetic studies of various medications is also reviewed. Based on this, we propose future perspectives on neonatal PBPK modeling and hope for its broader application.

Does closed-loop automated oxygen control reduce the duration of supplementary oxygen treatment and the amount of time spent in hyperoxia? A randomised controlled trial in ventilated infants born at or near term.

BACKGROUND: Ventilated infants frequently require supplemental oxygen, but its use should be monitored carefully due to associated complications. The achievement of oxygen saturation (SpO2) targets can be challenging as neonates experience frequent fluctuations of their oxygen levels that further increase the risk of complications. Closed-loop automated oxygen control systems (CLAC) improve achievement of oxygen saturation targets, reduce hyperoxaemic episodes and facilitate weaning of the inspired oxygen concentration in ventilated infants born at or near term. This study investigates whether CLAC compared with manual oxygen control reduces the time spent in hyperoxia and the overall duration of supplemental oxygen treatment in ventilated infants born at or above 34 weeks gestation. METHODS: This randomised controlled trial performed at a single tertiary neonatal unit is recruiting 40 infants born at or above 34 weeks of gestation and within 24 h of initiation of mechanical ventilation. Infants are randomised to CLAC or manual oxygen control from recruitment till successful extubation. The primary outcome is the percentage of time spent in hyperoxia (SpO2 > 96%). The secondary outcomes are the overall duration of supplementary oxygen treatment, the percentage of time spent with an oxygen requirement above thirty per cent, the number of days on mechanical ventilation and the length of neonatal unit stay. The study is performed following informed parental consent and was approved by the West Midlands-Edgbaston Research Ethics Committee (Protocol version 1.2, 10/11/2022). DISCUSSION: This trial will investigate the effect of CLAC on the overall duration of oxygen therapy and the time spent in hyperoxia. These are important clinical outcomes as hyperoxic injury is related to oxidative stress that can adversely affect multiple organ systems. TRIAL REGISTRATION: ClinicalTrials.Gov NCT05657795.

Association of Maternal Gestational Vitamin D Supplementation with Respiratory Health of Young Children.

This study aimed to evaluate the association between maternal gestational Vitamin D3 supplementation and early respiratory health in offspring. This was a population-based record-linkage study which used data from the French National Health Database System. Maternal Vitamin D3 supplementation consisted of a single high oral dose of cholecalciferol, (100,000 IU) from the seventh month of pregnancy, according to national guidelines. In total, 125,756 term-born singleton children were included, of which 37% had respiratory illness defined as hospital admission due to respiratory causes or inhalation treatment up to 24 months of age. Infants prenatally exposed to maternal Vitamin D3 supplementation (n = 54,596) were more likely to have a longer gestational age (GA) at birth (GA 36-38 weeks, 22% vs. 20%, p < 0.001 in exposed vs. non-exposed infants, respectively). After adjusting for the main risk factors (maternal age, socioeconomic level, mode of delivery, obstetrical and neonatal pathology, birth weight appropriateness, sex, and birth season), the risk of RD was found to be 3% lower than their counterparts (aOR [IC 95%], 0.97 [0.95-0.99], p = 0.01). In conclusion, this study provides evidence for the association between maternal gestational Vitamin D3 supplementation and improved early respiratory outcomes in young children.

Burden of Treatments for Respiratory Complications in Extremely Premature Infants: Interviews with Caregivers.

Introduction: Extremely premature (EP) infants (<28 weeks gestational age) with respiratory conditions after discharge from the neonatal intensive care unit (NICU) impose a significant burden on caregivers. This study explored caregiver burden post-NICU discharge and perceptions of meaningful change in infant chronic respiratory morbidity. Methods: Adult primary caregivers of EP infants 3-14 months corrected age were recruited through patient advocacy organizations or hospital centers in the USA, Northern Ireland, Germany, and Japan and interviewed by phone. Interviews explored caregiver experiences with infants with respiratory conditions, associated treatment burden, and meaningful change in infant respiratory morbidity as measured by treatment use. Qualitative analysis of interview data was performed using MAXQDA software. Sociodemographic data were summarized using descriptive statistics. Results: Forty-five caregivers (95.6% female) of EP infants were interviewed. Respiratory morbidities post-NICU discharge included coughing (78%), breathing difficulties (76%), wheezing (58%), and bronchopulmonary dysplasia/chronic lung disease of prematurity (56%). Respiratory medications were required by 87% of infants, 80% used home respiratory technology support (e.g., supplemental oxygen), 38% were re-hospitalized, and 33% had emergency department visits. Caregivers considered visits to the emergency department to be the most burdensome treatment requirement they experienced, and reduction in the number of emergency department visits was considered the most meaningful change in treatment use. Conclusion: These findings underscore the significant burden faced by caregivers of EP infants with respiratory morbidities. Development of treatments for respiratory complications should take into consideration the concerns and preferences of caregivers in order to provide a meaningful benefit.

Reliability and Repeatability of a Postural Control Test for Preterm Infants.

BACKGROUND: the current study aims to evaluate the reliability and repeatability of a new PT based on Center of Pressure (CoP) movement analysis in a repeated measures design. METHODS: the examination consisted of two parts: (1) the videotaping of General Movements (GMs) and GMs assessment (GMA) and (2) Posturometric Tests (PT) in supine and prone positions. PTs were performed twice (by two investigators) in the supine and prone positions using a force plate. Based on the GMA results, infants were stratified into two groups: (1) infants with normal FMs (indicating normal future motor outcomes) (n = 18) and (2) infants with abnormal FMs (indicating later neurological dysfunction) (n = 19). RESULTS: the comparative analysis between the groups of infants with normal FMs and abnormal FMs in PT in supine showed significant differences for all parameters that described spontaneous CoP displacement. The reliability analysis determined that all ICCs of the outcomes presented at least a moderate level of reliability. The ICCs were higher for outcomes of PT performed in the supine position than in the prone position. The ICCs were higher for outcomes of PT performed in infants with abnormal vs. normal FMs. CONCLUSIONS: although the current study yielded promising results, further longitudinal research in preterm infants should identify whether altered postural control parameters prognose future motor outcomes.

A cost-minimisation analysis comparing alternative telemedicine screening approaches for retinopathy of prematurity.

INTRODUCTION: Screening for retinopathy of prematurity (ROP) is an important procedure in the prevention of blindness in high-risk preterm infants. In the regionalised healthcare system of Queensland (Australia), outside of the major centres, some preterm infants are cared for in special care nurseries (SCNs). When necessary, infants in these nurseries who are at risk of ROP are transferred to a tertiary hospital for screening by paediatric ophthalmologists. The transport of preterm infants for eye examinations adds risk and incurs significant costs to the health system. Using a cost-minimisation approach, we aimed to compare the costs of the current ROP screening practice with two alternative telemedicine approaches. METHODS: We constructed a decision analytic model to estimate costs from a health service perspective with a five-year analysis horizon; activity data from a tertiary ROP screening service were used to inform the models. The three models assessed were: (a) a digital retinal photography (DRP)-equipped travelling nurse, (b) equipping SCNs with DRP, and providing training to local nurses, and (c) current practice of infant transfer. In all cases, the tertiary centre provides specialist ophthalmologic review. RESULTS: Of the three models, we estimated the most expensive option to be equipping SCNs with DRP and providing training to local nurses (AUD$4114/infant). We found that the current practice of transferring infants was the second most expensive (AUD$1021/infant). The most economical model was the specialist nurse travelling to each SCN with a portable DRP (AUD$363/infant). A sensitivity analysis, which assessed uncertainty and variability around the cost estimates, found that the ranking for the expected costs of the alternative models of care did not change. DISCUSSION: This is the first economic and cost-minimisation analysis in Australia to compare the costs of the current screening programme with two alternative telemedicine approaches for screening ROP. Telemedicine programmes that facilitate non-physician screening may improve the cost efficiency of the health system while maintaining the health outcomes for children, and reducing the risk associated with infant transport.

Kidney replacement therapy in neonates: utilization trends and outcomes.

BACKGROUND: We aimed to assess prevalence and clinical characteristics of newborns receiving kidney replacement therapy (KRT). METHODS: We used the National Inpatient Sample (NIS) dataset for the years 2000-2017. Newborns treated with peritoneal dialysis (PD), hemodialysis (HD), and continuous KRT (CKRT) were included. Trend analysis using the Cochran-Armitage test was used to assess prevalence over the years. RESULTS: A total of 64,532,552 hospitalized newborns were included. Among the 4281 infants treated with KRT, 2501 (58.4%) were treated with PD, 997 (23.3%) had HD, and 783 (18.3%) used CKRT. Associated diagnoses included congenital kidney anomalies (37.4% vs. 15% vs. 9.5%), urinary tract anomalies (35% vs. 12.5% vs. 6.3%), and congenital heart disease (68% vs. 25.7% vs. 72.3%). Median length of stay was longest in PD patients (39 days vs. 18 days vs. 26 days), respectively. However, cost of hospitalization was greatest in CKRT patients (US $490,916 vs. US $218,514 vs. US $621,554), respectively. In the entire cohort, 54,424 newborns had acute kidney injury (AKI); of them 16,999 (31%) died. KRT was used in 2,688 (4.9%) of infants with AKI. Over the study period, trends for utilization of PD (from 0.042 to 0.06%) and CKRT (from 0.03 to 0.21%) increased whereas the hemodialysis trend decreased (from 0.021 to 0.013%). CONCLUSIONS: Congenital heart disease (CHD) and congenital anomalies of the kidneys and urinary tract (CAKUT) are the major diagnoses in newborns receiving KRT. Utilization of PD was greater than HD and CKRT. Trends of PD and CKRT utilization increased over time. Less than 5% of infants diagnosed with AKI received KRT.

The Architecture of Early Childhood Sleep Over the First Two Years.

INTRODUCTION: The architecture and function of sleep during infancy and early childhood has not been fully described in the scientific literature. The impact of early sleep disruption on cognitive and physical development is also under-studied. The aim of this review was to investigate early childhood sleep development over the first two years and its association with neurodevelopment. METHODS: This review was conducted according to the 2009 PRISMA guidelines. Four databases (OVID Medline, Pubmed, CINAHL, and Web of Science) were searched according to predefined search terms. RESULTS: Ninety-three studies with approximately 90,000 subjects from demographically diverse backgrounds were included in this review. Sleep is the predominant state at birth. There is an increase in NREM and a decrease in REM sleep during the first two years. Changes in sleep architecture occur in tandem with development. There are more studies exploring sleep and early infancy compared to mid and late infancy and early childhood. DISCUSSION: Sleep is critical for memory, learning, and socio-emotional development. Future longitudinal studies in infants and young children should focus on sleep architecture at each month of life to establish the emergence of key characteristics, especially from 7-24 months of age, during periods of rapid neurodevelopmental progress.

Identification of risk factors in pre-term infants with abnormal general movements.

Introduction: This study aimed to investigate the relationship between prenatal, perinatal, and postnatal risk factors for neurodevelopmental impairment (NDI) with the outcomes of General Movement (GM) Assessment (GMA) in pre-term infants at 3-5 months of age. We sought to identify the risk factors associated with the predictors of psychomotor development in pre-term newborns, such as normal fidgety movements (FMs), absent FMs, or abnormal FMs, assessed during the fidgety period of motor development. Methods: The SYNAGIS program (prophylactic of Respiratory Syncytial Virus Infection) was used to identify risk factors for the development of neuromotor deficits in 164 pre-term infants who were at high risk of developing these deficits. Based on the GMA, all participants were divided into three groups of infants who presented: (1) normal FMs; (2) absent FMs; and (3) abnormal FMs. Results: The results of the current study suggest that abnormal GMs not only indicate commonly known factors like birth asphyxia (BA), respiratory distress syndrome (RDS), periventricular leukomalacia (PVL), intraventricular hemorrhage (IVH) grades 3-4, but also predict the development of motor impairments. In the present study, several specific risk factors including bronchopulmonary dysplasia (BPD), infertility treatments, maternal acute viral/bacterial infections during pregnancy, and elevated bilirubin levels were identified as attributes of an atypical fidgety movement pattern. Conclusions: Additional clinical data, such as risk factors for NDI associated with early predictors of psychomotor development in pre-term newborns, i.e., absent or abnormal FMs, may be helpful in predicting neurological outcomes in pre-term infants with developmental concerns in the 1st month of life.

Predicting resolution of hypoglycemia with and without dextrose infusion in newborn infant of gestational diabetic mothers.

Introduction: Neonatal hypoglycemia (NH) may lead to significant neurological impairment if left untreated. Infants of gestational diabetic mothers (IGDM) are at increased risk of early NH and need to be screened. However, it is challenging to predict management with or without intravenous dextrose once hypoglycemia is identified. We evaluated the association between hypoglycemia risk scores at 1-hour of life and the need for intravenous dextrose for hypoglycemia resolution in IGDM. Methods: This was a retrospective cohort study of IGDM born at a gestational age ≥35 weeks from January 2015 to December 2017. NH was the disease of interest. The outcomes were the association of hypoglycemia risk score (HRS) with and without intravenous dextrose for hypoglycemia resolution. Each infant's hypoglycemia risk score (HRS) was calculated using data extracted from the maternal and neonatal electronic medical records. Resolution of hypoglycemia with and without intravenous dextrose was compared between the low HRS (0-1) group and the high HRS (2-5) group. Results: Sixty-five infants were included in the study with a mean gestational age of 38.2 ± 1 weeks for low HRS and 38.0 ± 2 weeks for high HRS. While more children with high HRS were delivered by cesarean section (p = 0.04), hypoglycemia resolved more frequently without intravenous dextrose in infants with low HRS (p = 0.03). Conclusion: IGDM is at increased risk of NH. The resolution of hypoglycemia without dextrose infusion is frequently associated with low HRS at 1-hour of life. Early identification using HRS of IGDM whose hypoglycemia will resolve with or without intravenous dextrose may help clinicians triage newborns to either stay in the nursery or transfer for more invasive care.

Interventions to Improve Breastfeeding Outcomes in Late Preterm and Early Term Infants.

Background: Late preterm infants (LPIs; born at 340/7 to 366/7 gestational weeks) and early term infants (ETIs; 370/7 to 386/7 gestational weeks) are at higher risk of morbidity and mortality compared with more mature infants. Breastfeeding can reduce these risks, but feeding difficulties are common among these infants and breastfeeding rates are low. We conducted a systematic review to identify the interventions available to improve any breastfeeding, exclusive breastfeeding, or breast milk yield. Methods: A literature search was performed up to February 23, 2022, using MEDLINE, CINAHL, Embase, and Google Scholar, and nine articles were included. Only one article was a randomized controlled trial, and only one included ETIs. The remaining articles were quasi-experimental and included only LPIs. Outcomes included breastfeeding duration, breastfeeding exclusivity, and/or breast milk production (volume) before 6 months actual age. Results: Professional support significantly improved exclusive breastfeeding rates. A breastfeeding education program delivered at the hospital with weekly telephone follow-up postdischarge significantly increased breastfeeding rates. Neither cup feeding nor early discharge (with in-home lactation support) improved breastfeeding rates, whereas rooming-in (versus direct admission to the neonatal intensive care unit) worsened exclusive breastfeeding rates. Discussion: This is the first systematic review to identify interventions available for both LPIs and ETIs. Overall, there are limited studies that investigate interventions promoting breastfeeding in these populations. However, breastfeeding support delivered by health care professionals seems to improve breastfeeding rates. The main limitations are the lack of randomization, blinding, and adjustment for confounding variables. Experimental studies with robust methodological design are needed.
