    背景:根据世界卫生组织的建议,延迟脐带夹紧在足月新生儿可以有各种好处。Cochrane荟萃分析报告死亡率和早期新生儿发病率没有差异,尽管有限数量的研究调查了长期神经发育结局。我们研究的目的是比较选择性剖宫产后出生的早期和延迟脐带钳夹婴儿的出生后脑组织氧合值。
    方法:在本研究中,共纳入80例择期剖宫产分娩的足月新生儿.婴儿被随机分组为早期(在15s内夹住,n:40)和延迟的电源线夹紧(在第60秒,n:40)组。通过脉搏血氧饱和度测量外周动脉血氧饱和度(SpO2)和心率,而使用近红外光谱仪测量大脑的局部氧饱和度(rSO2)。在出生后第3分钟至第15分钟之间,计算每分钟的组织氧提取分数(FTOE)。(FTOE=脉搏血氧饱和度值-rSO2/脉搏血氧饱和度值)。比较两组的测量值。
    结果:人口统计学特征,SpO2水平(除了产后6,8th,第14分钟有利于DCCp<0.05),心率和脐血血气值组间差异无统计学意义(p>0.05)。在延迟脐带钳夹组中,出生后第3分钟至第15分钟的每分钟rSO2值显着升高,而FTOE值显着降低(p<0.05)。
    结论:我们的研究表明,延迟脐带钳夹(DCC)组的大脑rsO2值显着增加,而FTOE值降低,表明对脑氧合和血流动力学有积极影响。此外,DCC组脑rSO2水平高于第90百分位数的婴儿比例较高。这一比例较高,以及这些参数低于10个百分位数的较低的人,提示DCC可能导致这些婴儿的靶向/最佳脑氧合。因此,我们建议测量脑氧合,除了外周SpO2,对于经历围产期缺氧和接受补充氧气的婴儿。
    BACKGROUND: According to the World Health Organization\'s recommendation, delayed cord clamping in term newborns can have various benefits. Cochrane metaanalyses reported no differences for mortality and early neonatal morbidity although a limited number of studies investigated long-term neurodevelopmental outcomes. The aim of our study is to compare the postnatal cerebral tissue oxygenation values in babies with early versus delayed cord clamping born after elective cesarean section.
    METHODS: In this study, a total of 80 term newborns delivered by elective cesarean section were included. Infants were randomly grouped as early (clamped within 15 s, n:40) and delayed cord clamping (at the 60th second, n:40) groups. Peripheral arterial oxygen saturation (SpO2) and heart rate were measured by pulse oximetry while regional oxygen saturation of the brain (rSO2) was measured with near-infrared spectrometer. Fractional tissue oxygen extraction (FTOE) was calculated for every minute between the 3rd and 15th minute after birth. (FTOE = pulse oximetry value-rSO2/pulse oximetry value). The measurements were compared for both groups.
    RESULTS: The demographical characteristics, SpO2 levels (except postnatal 6th, 8th, and 14th minutes favoring DCC p < 0.05), heart rates and umbilical cord blood gas values were not significantly different between the groups (p > 0.05). rSO2 values were significantly higher while FTOE values were significantly lower for every minute between the 3rd and 15th minutes after birth in the delayed cord clamping group (p < 0.05).
    CONCLUSIONS: Our study revealed a significant increase in cerebral rsO2 values and a decrease in FTOE values in the delayed cord clamping (DCC) group, indicating a positive impact on cerebral oxygenation and hemodynamics. Furthermore, the DCC group exhibited a higher proportion of infants with cerebral rSO2 levels above the 90th percentile. This higher proportion, along with a lower of those with such parameter below the 10th percentile, suggest that DCC may lead to the targeted/optimal cerebral oxygenetaion of these babies. As a result, we recommend measuring cerebral oxygenation, in addition to peripheral SpO2, for infants experiencing perinatal hypoxia and receiving supplemental oxygen.

    背景:坏死性小肠结肠炎(NEC)和颅内出血是新生儿期的严重紧急情况。这两者似乎并不相关。然而,我们的报告提示,足月新生儿脑实质出血可能通过脑-肠轴改变肠功能,使患者面临NEC风险.
    方法:我们介绍一例足月新生儿自发性脑实质出血病例,该病例在第15天发生早期NEC。
    结论:可能认为脑实质出血是NEC出现的危险因素。临床医生应高度谨慎的NEC在经历过实质性出血的婴儿。本文首次讨论足月新生儿实质性出血与NEC的关系。
    BACKGROUND: Necrotizing enterocolitis (NEC) and intracranial hemorrhage are severe emergencies in the neonatal period. The two do not appear to be correlated. However, our report suggests that parenchymal brain hemorrhage in full-term newborns may put patients at risk for NEC by altering intestinal function through the brain-gut axis.
    METHODS: We present a case of spontaneous parenchymal cerebral hemorrhage in a full-term newborn who developed early-stage NEC on Day 15.
    CONCLUSIONS: It is possible to consider brain parenchymal hemorrhage as a risk factor for the appearance of NEC. Clinicians should be highly cautious about NEC in infants who have experienced parenchymal hemorrhage. This article is the first to discuss the relationship between parenchymal hemorrhage and NEC in full-term newborns.

    以前的超声心动图研究主要集中在早产儿和早期胎儿到新生儿过渡期,而对生命72小时后右心室(RV)功能参数的变化知之甚少。我们的目的是通过超声心动图定量表征健康足月新生儿在生命的第3天至第7天之间的RV功能的潜在变化。我们在35名足月新生儿中进行了一项前瞻性观察研究,我们在生命的第三天和第七天进行了超声心动图检查。我们评估了RV功能,输出和后负荷,并发现所有组织多普勒速度以及RV纵向应变显着增加,较高的平均RV流出道速度时间积分和较低的心肌性能指数(MPI),而三尖瓣环平面收缩期偏移,RV填充模式,和RV流出道加速时间在第3天和第7天之间没有显著差异。结论:RV收缩期和舒张期心肌速度增加,在生命的第3天和第7天之间,心输出量和纵向变形以及RVMPI下降表明在此期间足月新生儿的RV后负荷和适应性心肌成熟减少。此外,与M型超声心动图和RV充盈的脉冲多普勒分析相比,PW-TDI和2D斑点追踪超声心动图似乎对评估RV功能更敏感。
    Previous echocardiographic studies were mainly focused on preterm infants and early fetal-to-neonatal transition period, whereas little is known about changes in the parameters of the right ventricular (RV) function after 72 h of life. Our aim was to quantitatively characterize potential changes in RV function by echocardiography in healthy term newborns between the third and the seventh day of life. We conducted a prospective observational study in 35 full-term newborns, in whom we performed echocardiographic examinations on the third and the seventh day of life. We assessed RV function, output and afterload and found a significant increase in all tissue Doppler velocities as well as in RV longitudinal strain, a higher mean RV outflow tract velocity time integral and lower myocardial performance index (MPI\'), whereas the tricuspid annular plane systolic excursion, RV filling pattern, and RV outflow tract acceleration time were not significantly different between the third and the seventh day of life. Conclusions: Increased RV systolic and diastolic myocardial velocities, cardiac output and longitudinal deformation and decreased RV MPI\' between the third and the seventh day of life point to a reduction of RV afterload and adaptive myocardial maturation in term newborns during this period. Moreover, PW-TDI and 2D speckle-tracking echocardiography seem to be more sensitive for evaluating RV function in comparison with M-mode echocardiography and pulsed-wave Doppler analysis of RV filling.

    Background: Anterior fontanel is an integral element of an infant craniofacial system. There are six fontanels in the newborn skull, namely anterior, posterior, two mastoid, and two sphenoid fontanels. The anterior fontanel is the largest, prominent, and most important for clinical evaluation. Sex, race, genetics, gestational age, and region are the principal factors that influence anterior fontanel size. There exist inconclusive findings on the size of anterior fontanel in newborns. Therefore, this systematic review and meta-analysis aimed to determine the pooled mean size of anterior fontanel among term newborns and to identify the pooled mean difference of anterior fontanel size between males and females. Methods: PubMed/Medline, Google Scholar, Science Direct, JBI Library, embase, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction format. The heterogeneity across studies was assessed using the Cochrane Q test statistic, I2 test statistic, and p-values. A fixed-effect model and random effect model were used to estimate the pooled mean size of anterior fontanel and the pooled mean difference between male newborns and female newborns, respectively. To deal with heterogeneity, sub-group analysis, meta-regression analysis, and sensitivity analysis were considered. JBI quality appraisal checklist was used to evaluate the quality of studies. Results: In this meta-analysis, 8, 661 newborns were involved in twenty-six studies. Among studies, 13 conducted in Asia, 7 in Africa, 5 in America, and 1 in Europe. The pooled mean size of anterior fontanel was 2.58 cm (95% CI: 2.31, 2.85 cm). The pooled mean size of anterior fontanel for Asia, Africa, America, and Europe region was 2.49, 3.15, 2.35, and 2.01 cm, respectively. A statistically significant mean difference was detected between male and female newborns (D + L pooled MD = 0.15 cm, 95% CI: 0.02, 0.29 cm). Conclusion: The pooled estimate of this review does provide the mean value of the anterior fontanel size in the newborns. There was a statistically significant mean fontanel size difference between male and female newborns. Therefore, male newborns had a significantly larger mean size than female newborns.

    BACKGROUND: Pasteurized donor milk (PDM) is typically prescribed to preterm or low birthweight newborns when their mother\'s own milk is unavailable. In surplus, PDM is prescribed to meet the nutritional needs of healthy newborns in the first few days of life. However, its overuse can undermine efforts to promote and support breastfeeding, waste resources, and reduce the availability of PDM for at-risk newborns. We conducted this study to examine factors associated with the prescription and prolonged use (>48 h) of privately purchased PDM to healthy newborns.
    METHODS: Prospective observational study of 2440 mothers of healthy, term, and normal birthweight newborns born at Da Nang Hospital for Women and Children between April and August 2019. In addition to the descriptive analysis, we performed multiple logistic regressions to examine factors associated with the prescription of PDM (n = 2440) and prolonged PDM use among those who used PDM (n = 566).
    RESULTS: Twenty-three percent (566/2440) of healthy, term, and birthweight ≥2500 g newborns received PDM and were included in the study. The prevalence of PDM use was higher for cesarean births (OR: 2.05; 95% CI: 1.66, 2.55) and among male newborns (OR: 1.33; 95% CI: 1.09, 1.62), but lower for farmers or workers (vs. other jobs; OR: 0.71; 95% CI: 0.54, 0.93), family income <10 million VND (vs. ≥10 million VND; OR: 0.67; 95% CI: 0.55, 0.82), and duration of skin-to-skin ≥90 min (vs. <90 min; OR: 0.54; 95% CI: 0.39, 0.76). Prolonged PDM use (12.4% of 566 newborns who used PDM) was associated with the mother having a higher socioeconomic status job (professional, small trader or homemaker; OR: 4.00; 95% CI: 1.39, 12.5), being a first-time mother (OR: 3.39; 95% CI: 1.92, 6.01) or having a cesarean birth (OR: 2.09; 95% CI: 1.02, 4.28).
    CONCLUSIONS: The prescription and prolonged use of privately purchased PDM was associated with non-medical factors unrelated to the ability to breastfeed effectively. The findings suggest the need for improved breastfeeding communication, counseling and support skills for health staff, development, and application of strict criteria on PDM use for healthy newborns and better routine monitoring of PDM use over time.

    The mature central autonomic network includes connectivity between autonomic nervous system brainstem centers and the cerebral cortex. The study objective was to evaluate the regional connectivity between the cerebral cortex and brainstem autonomic centers in term newborns by measuring coherence between high-density electroencephalography and heart rate variability as measured by electrocardiography.
    Low-risk term newborns with birth gestational age of 39-40 weeks were prospectively enrolled and studied using time-synced electroencephalography and electrocardiography for up to 60 min before discharge from the birth hospital. The ccortical autonomicc nervous system association was analyzed using coherence between electroencephalography-delta power and heart rate variability. Heart rate variability measured the parasympathetic tone (root mean square of successive differences of heart rate) and sympathetic tone (standard deviation of heart rate).
    One hundred and twenty-nine low-risk term infants were included. High coherence delta-root mean square of successive differences was found in central, bitemporal, and occipital brain regions, with less robust coherence delta-standard deviation in the central region and bitemporal areas.
    Our findings describe a topography of ccortical autonomicc connectivity present at term in low-risk newborns, which was more robust to parasympathetic than sympathetic brainstem centers and was independent of newborn state.

    To compare the course of the transcutaneous bilirubin (TcB) values of early-term newborns with those of term newborns in the first month of life and to investigate whether early-term newborns have an increased risk of significant hyperbilirubinemia requiring treatment.
    A prospective, controlled cohort analysis.
    A tertiary level mother-child birth and health care center.
    Four hundred early-term (37 0/7 to 38 6/7 weeks) and 320 term (39 0/7 to 41 6/7 weeks) newborns born during a 27-month period.
    A total of six TcB measurements in a longitudinal manner were made in early-term and term newborns: the first two at 6 and 48 hours after birth and the next four on routine examination days (Days 4, 7, 15, and 30). Demographic characteristics, values of daily TcB measurements, number of newborns with significant hyperbilirubinemia, and risk of jaundice requiring treatment were compared between the two groups.
    All six TcB values were significantly greater in the early-term group than in the term group (p < .001 for each). Early-term newborns had a statistically significant increased risk of jaundice requiring treatment compared to term newborns (risk ratio = 1.91; 95% confidence interval [1.23-2.96]; p = .0046). Results of the repeated-measures analysis of variance and post hoc adjusted multiple comparison analysis showed that TcB levels increased to and peaked at 96 hours after birth and then gradually decreased to baseline (first measurement) levels at 30 days after birth in each group.
    Early-term newborns should not be treated as full-term newborns because they have significantly higher TcB levels. These newborns should be closely monitored for pathologic jaundice because they have increased risk for significant hyperbilirubinemia requiring phototherapy.

    Electroencephalography (EEG) is the reference tool for the analysis of brain function, reflecting normal and pathological neuronal network activity. During the neonatal period, EEG patterns evolve weekly, according to gestational age. The first analytical criteria for the various maturational stages and standardized neonatal EEG terminology were published by a group of French neurophysiologists training in Paris (France) in 1999. These criteria, defined from analog EEG, were completed in 2010 with digital EEG analysis. Since then, this work has continued, aided by the technical progress in EEG acquisition, the improvement of knowledge on the maturating processes of neuronal networks, and the evolution of critical care. In this review, we present an exhaustive and didactic overview of EEG characteristics from extremely premature to full-term infants. This update is based on the scientific literature, enhanced by the study of normal EEGs of extremely premature infants by our group of neurophysiologists. For educational purposes, particular attention has been paid to illustrations using new digital tools.

    目的:进行这项研究以评估母乳和配方奶的气味对减轻足跟刺血采样过程中新生儿急性疼痛的影响。方法:将84例新生儿随机分为两组(配方乳组和母乳组),共42例婴儿搜索。新生儿以前感受到的疼痛,during,并使用新生儿婴儿疼痛量表评估脚跟点刺采血后;用脉搏血氧计测量他们的心率和血氧饱和度。在采样之前和之后从新生儿身上采集唾液样本,测量了他们的唾液皮质醇水平。采样期间,新生儿的哭声持续时间用计时器记录。结果:母乳组新生儿的痛阈和心率明显低于配方乳组(p<0.001)。与母乳组相比,配方乳组的唾液皮质醇增加,这些婴儿的氧饱和度水平下降更明显(p<0.05)。结论:母乳的气味可能有助于减轻足跟刺血过程中新生儿的疼痛。
    Purpose: This study was carried out to assess the effect of the odor of breast milk and formula milk on reducing the acute pain of newborn infants during the heel-prick blood sampling. Methods: Eighty-four newborn were randomly assigned into two groups (formula milk group and breast milk group) with 42 infant searches. The pain that the newborn felt before, during, and after heel-prick blood sampling was assessed using Neonatal Infant Pain Scale; their heart rate and blood oxygen saturation were measured with a pulse oximeter. Saliva samples were taken from newborns before and after sampling, and their salivary cortisol level was measured. During sampling, the crying duration of newborn was recorded with a chronometer. Results: The pain threshold and heart rates of the newborn in the breast milk group were significantly lower than those in the formula milk group (p < 0.001). Salivary cortisol in the formula milk group increased and oxygen saturation levels in these infants decreased significantly more as compared to the breast milk group (p < 0.05). Conclusions: The odor of breast milk may be helpful in reducing the pain of newborn during heel-prick blood sampling.

    BACKGROUND: Transient tachypnea of the newborn(TTNB) is the most common respiratory morbidity in late preterm and term babies and is pathophysiologically related to delayed lung fluid clearance after birth. Mimicking low physiological fluid intake in the initial period of life may accelerate the recovery from TTNB. In a randomized controlled trial, we compared the roles of restricted versus standard fluid management in babies with TTNB requiring respiratory support.
    METHODS: This parallel group,non-blinded, stratified randomized controlled trial was conducted in a level III neonatal unit of eastern India. Late preterm and term babies with TTNB requiring continuous positive airway pressure (CPAP) were randomly allocated to standard and restricted fluid arms for the first 72 hours (hrs). Primary outcome was CPAP duration.
    RESULTS: In total, 100 babies were enrolled in this study with 50 babies in each arm. CPAP duration was significantly less in the restricted arm (48[42, 54] hrs vs 54[48,72] hrs, p = 0.002). However, no difference was observed in the incidence of CPAP failure between the two arms. In the subgroup analysis, the benefit of reduced CPAP duration persisted in late preterm but not in term infants. However, the effect was not significant in the late preterm babies exposed to antenatal steroid.
    CONCLUSIONS: This trial demonstrated the safety and effectiveness of restrictive fluid strategy in reducing CPAP duration in late preterm and term babies with TTNB. Late preterm babies, especially those not exposed to antenatal steroid were the most benefitted by this strategy.
