RESUMEN
Objective: To investigate the impact of parity-customized versus population-based birth weight charts on the identification of neonatal risk for adverse outcomes in small (SGA) or large for gestational age (LGA) infants compared to appropriate for gestational age (AGA) infants. Study design: Observational, retrospective, cohort study based on electronic medical birth records at a single center between 2006 and 2017. Neonates were categorized by birth weight (BW) as SGA, LGA, or AGA, with the 10th and 90th centiles as boundaries for AGA in a standard population-based model adjusted for gestational age and gender only (POP) and a customized model adjusted for gestational age, gender, and parity (CUST). Neonates defined as SGA or LGA by one standard and not overlapping the other, are SGA/LGA CUST/POP ONLY. Analyses used a reference group of BW between the 25th and 75th centile for the population. Results: Overall 132,815 singleton, live, term neonates born to mothers with uncomplicated pregnancies were included. The customized model identified 53% more neonates as SGA-CUST ONLY who had significantly higher rates of morbidity and mortality compared to the reference group (OR = 1.33 95% CI [1.16−1.53]; p < 0.0001). Neonates defined as LGA by the customized model (LGA-CUST) and AGA by the population-based model LGA-CUST ONLY had a significantly higher risk for morbidity compared to the reference (OR = 1.36 95% CI [1.09−1.71]; p = 0.007) or the LGA POP group. Neonatal mortality only occurred in the SGA and AGA groups. Conclusions: The application of a parity-customized only birth weight chart in a population of singleton, term neonates is a simple platform to better identify birth weight related neonatal risk for morbidity and mortality.
RESUMEN
BACKGROUND: Neonatal jaundice occurs in approximately 60% of term newborns. Although risk factors for neonatal jaundice have been studied, all the suggested strategies are based on various newborn tests for bilirubin levels. We aim to stratify neonates into risk groups for clinically significant neonatal jaundice using a combined data analysis approach, without serum bilirubin evaluation. STUDY DESIGN: Term (gestational week 37-42) neonates born in a single medical center, 2005-2018 were identified. Anonymized data were analyzed using machine learning. Thresholds for stratification into risk groups were established. Associations were evaluated statistically using neonates with and without clinically significant neonatal jaundice from the study population. RESULTS: A total of 147,667 consecutive term live neonates were included. The machine learning diagnostic ability to evaluate the risk for neonatal jaundice was 0.748; 95% CI 0.743-0.754 (AUC). The most important factors were (in order of importance) maternal blood type, maternal age, gestational age at delivery, estimated birth weight, parity, CBC at admission, and maternal blood pressure at admission. Neonates were then stratified by risk: 61% (n = 90,140) were classed as low-risk, 39% (n = 57,527) as higher-risk. Prevalence of jaundice was 4.14% in the full cohort, and 1.47% and 8.29% in the low- and high-risk cohorts, respectively; OR 6.06 (CI: 5.7-6.45) for neonatal jaundice in high-risk group. CONCLUSION: A population tailored "first step" screening policy using machine learning model presents potential of neonatal jaundice risk stratification for term neonates. Future development and validation of this computational model are warranted.

OBJECTIVE: The aim of the study is to evaluate the effect of the coronavirus disease 2019 (COVID-19) pandemic national lockdown period on the rate of singleton preterm births in Israel. STUDY DESIGN: This is a population-based cohort study of 3,41,291 singleton infants born in the months of January to July 2017 to 2020. Multivariable logistic regression analyses were used to estimate the influence of period and year on the rates of preterm births during the lockdown period (11th March - 5th May 2020) compared with rates before (January 1st 2020 - March 10th 2020), and after the lockdown (May 6th 2020-June 30th 2020) and to the corresponding periods in 2017to 2019. RESULTS: During the lockdown period the preterm birth rate (primary outcome) decreased by 9.7% from 5.05 to 4.56% in the pre-lockdown period (p = 0.006), an adjusted decrease of -0.52% (95% confidence interval -0.89%; -0.15%), odds ratio 0.898 (95% confidence interval 0.832; 0.970). CONCLUSION: The rate of singleton preterm births declined by 9.7% during the COVID-19 pandemic national lockdown period in Israel. KEY POINTS: · A 10% decline in all preterm deliveries was observed during the COVID-19 pandemic national lock-down period.. · The lock-down might influence environmental changes which contribute to the decrease in preterm deliveries.. · Changes in lifestyle, and societal behavior might contribute to the decrease in preterm deliveries..

BACKGROUND: Many countries have adopted a mandatory routine pulse oximetry screening of newborn infants to identify babies with otherwise asymptomatic critical congenital heart disease (CCHD). OBJECTIVES: To describe the current status of pulse oximetry CCHD screening in Israel, with a special emphasis on the experience of the Shaare Zedek Medical Center. METHODS: We review the difficulties of the Israeli Medical system with adopting the SaO2 screening, and the preliminary results of the screening at the Shaare Zedek Medical Center, both in terms of protocol compliance and CCHD detection. RESULTS: Large scale protocol cannot be implemented in one day, and regular quality assessment programs must take place in order to improve protocol compliance and identify the reasons for protocol failures. CONCLUSIONS: Quality control reviews should be conducted soon after implementation of the screening to allow for prompt diagnosis and quick resolution.

OBJECTIVE: To investigate the success rate of intramuscular (IM) glucagon in preventing need for IV glucose and describe its glycemic effect. METHODS: Retrospective study of 158 consecutive term neonates with feeding-resistant hypoglycemia treated with glucagon. RESULTS: After glucagon, blood glucose (BG) increased in all but 1 infant by 25.9 ± 17.1, 42.1 ± 21.1, and 39.2 ± 28.3 mg/dL (1.4 ± 0.9, 2.3 ± 1.2, 2.2 ± 1.6 mmol/L) at 30, 60 and 120 mins respectively. In multivariable logistic regression, glucagon success was dependent upon gender (increased male risk) (P = 0.021), meeting American Academy of Pediatrics (AAP) criteria for immediate IV glucose (P = 0.004), birth weight, (P = 0.018) and delta glucose concentration at 60 min (P = 0.013). After IM glucagon, 24 out of 49 infants that met AAP criteria for immediate IV glucose (49%) ended up not requiring any additional intervention. CONCLUSIONS: Glucagon increases BG nearly universally in hypoglycemic infants and allowed reducing the number of infants that needed immediate IV glucose infusion therapy by ≈half.

OBJECTIVE: We tested whether mothers of neonates with Down syndrome (DS) prefer to get the diagnosis after delivery in a one-step approach or in a two-step one (information about suggestive findings, followed by additional explicit meeting). METHODS: Mothers were asked whether (1) they had been informed in one or two steps; (2) they would have preferred the other approach. RESULTS: Of 45 women who completed the questionnaires, 18 (40%) had been informed in a one step and 27 (60%) in two steps. Thirteen of the 18 mothers (72.2%) informed in one step were satisfied with the manner they had been informed, while 19 (70.4%) in the two-step group expressed satisfaction. CONCLUSION: Mothers were generally satisfied with the method chosen with them. We speculate that an adaptive, supportive, empathic, caring and honest approach, taking into consideration family cultural and religious backgrounds may be able to optimize the delivery of such news.

BACKGROUND: Despite a gradual reduction in the workload during residency, 24-hour calls are still an integral part of most training programs. While sleep deprivation increases the risk propensity, the impact on medical risk taking has not been studied. OBJECTIVE: This study aimed to assess the clinical decision making and psychomotor performance of pediatric residents following a limited nap time during a 24-hour call. METHODS: A neurocognitive battery (IntegNeuro) and a medical decision questionnaire were completed by 44 pediatric residents at 2 time points: after a 24-hour call and following 3 nights with no calls (sleep ≥5 hours). To monitor sleep, residents wore actigraphs and completed sleep logs. RESULTS: Nap time during the shift was <1 hour in 14 cases (32%), 1 to 2 hours in 16 cases (35%), and 2 to 3 hours in 14 cases (32%). Residents who napped less than 1 hour chose the riskier medical option in 50% of cases compared with 36% when answering the same questionnaire after 3 nights with no calls (P = 0.002). This effect was not found in residents who napped 1 to 2 hours (no change in risk taking) or 2 to 3 hours (4% decreased risk taking) (difference between groups, P = 0.001). Risk-taking tendency inversely correlated with sustained attention scores (Pearson = -0.433, P = 0.003). Sustained attention was the neurocognitive domain most affected by sleep deprivation (effect size = 0.29, P = 0.025). CONCLUSIONS: This study suggests that residents napping less than an hour during a night shift are prone to riskier clinical decisions. Hence, enabling residents to nap at least 1 hour during shifts is recommended.

BACKGROUND: Due to decreased hospital stay, follow-up of unresolved medical problems of babies with uncomplicated postpartum course is relegated to outpatient clinics. OBJECTIVE: To identify factors in discharge letters that influence parent compliance. METHODS: Telephone contact with parents three months after discharge queried compliance with routine and special instructions as written in discharge letters. Statistical analyses compared responses of compliant versus less compliant parents. P<0.05 was considered to be statistically significant. The present study was approved by the Institutional Ethical Review Board Committee. RESULTS: Of the 2000 discharge letters, 319 (16%) included special instructions. Parents of 252 infants (79%) who received discharge letters containing 332 special instructions were interviewed by telephone. Compliance was greater for noninvasive instructions (86%) relative to others (57.8%) (P<0.001). Initiation of follow-up visits was correlated with parity (P<0.001) and maternal age (P<0.001). CONCLUSION: Discharge letters should be read and discussed with parents before infants are discharged, and the relevance of specific medical instructions should be emphasized.
