    该病例报告调查了24周龄新生儿先天性巨细胞病毒(CMV)感染及其后遗症的处理,包括严重的宫内生长受限,血小板减少症,和大脑异常,最终进展为脑畸形。诊断挑战包括延迟临床怀疑先天性CMV,直到通过CMVDNA聚合酶链反应递送后才被鉴定出来,并将其症状与新生儿病情的其他潜在原因区分开来。积极的干预措施包括抗生素,更昔洛韦抗病毒治疗,以及插管等支持性措施,CPR,呼吸支持,输血,和凝血功能障碍的管理。尽管做出了这些努力,患者由于进行性灌注不足而恶化,低氧性心肺衰竭,和弥散性血管内凝血病。由于多器官损害的不良预后和程度,根据父母的同意,支持被撤回。该病例强调了管理晚期新生儿CMV感染时遇到的并发症,并强调了多学科和整体方法指导诊断和治疗的重要性。
    This case report investigates the management of a 24-week-old neonate with congenital cytomegalovirus (CMV) infection and its sequelae, including severe intrauterine growth restriction, thrombocytopenia, and brain anomalies, ultimately progressing to lissencephaly. The diagnostic challenges included delayed clinical suspicion of congenital CMV, which was not identified until after delivery through CMV DNA polymerase chain reaction, and differentiating its symptoms from other potential causes of the neonate\'s condition. Aggressive interventions included antibiotics, antiviral therapy with ganciclovir, and supportive measures such as intubation, CPR, respiratory support, blood transfusions, and management of coagulopathy. Despite these efforts, the patient deteriorated due to progressive hypoperfusion, hypoxemic cardiorespiratory failure, and disseminated intravascular coagulopathy. Due to the poor prognosis and extent of multiorgan damage, support was withdrawn per parental consent. This case highlights the complications encountered when managing an advanced-stage neonatal CMV infection and emphasizes the importance of a multidisciplinary and holistic approach to guide diagnosis and treatment.

    背景:呼吸窘迫综合征(RDS)是早产儿中最重要和最常见的疾病之一。
    目的:本研究旨在比较表面活性剂和布地奈德与表面活性剂单独联合治疗对RDS早产儿支气管肺发育不良(BPD)和死亡率的影响。
    方法:对在阿亚图拉穆萨维医院出生的134名RDS早产儿进行了一项结局评估盲随机临床试验,Zanjan,2021年伊朗。使用协变量自适应随机化方法将参与者分为两组(单独的表面活性剂以及表面活性剂和布地奈德的组合)。主要结果是从入院到出院的BPD和死亡率。本研究中的数据使用SPSS软件版本18进行分析。
    结果:两组之间死亡率和BPD的总体比较没有显着差异(p>0.05)。亚组结果显示,与单独使用表面活性剂相比,向30周龄以下的婴儿施用表面活性剂与布地奈德显著减少了死亡人数(5vs.17).肺出血的发生也观察到了类似的积极作用,需要第二剂表面活性剂,氧指数,34周龄以下婴儿的平均血压和平均动脉压(MAP)与超过34周龄的婴儿相比(p<0.05)。
    结论:这些研究结果表明,表面活性剂和布地奈德联合治疗可能是有益的,特别是小于34周胎龄和1500出生体重的早产儿。然而,需要更多样本量和更长随访时间的进一步研究来确认这些结果并评估长期结局.

    BACKGROUND: Respiratory distress syndrome (RDS) is one of the most important and common disorders among premature infants.
    OBJECTIVE: This study aimed to compare the effect of the combination of surfactant and budesonide with surfactant alone on Bronchopulmonary dysplasia (BPD) and mortality rate among premature infants with RDS.
    METHODS: An outcome assessor-blind randomized clinical trial was conducted on 134 premature infants with RDS who were born in Ayatollah Mousavi Hospital, Zanjan, Iran in 2021. The covariate adaptive randomization method was utilized to allocate participants into two groups (surfactant alone and a combination of surfactant and budesonide). The primary outcomes were BPD and Mortality rate from admission to hospital discharge. The data in this study were analyzed using SPSS software version 18.
    RESULTS: Overall the comparison of mortality rate and BPD between the two groups did not show a significant difference(p > 0.05). The subgroup results showed that administering surfactant with budesonide to infants under 30 weeks of age significantly reduced the number of deaths compared to using surfactant alone (5 vs. 17). Similar positive effects were observed for the occurrence of Pulmonary Hemorrhage, the need for a second dose of surfactant, oxygen index, mean blood pressure and mean arterial pressure (MAP) in infants under 34 weeks of age compared to more than 34 weeks (p < 0.05).
    CONCLUSIONS: These findings suggest that the combination therapy of surfactant and budesonide may be beneficial, particularly in preterm infants with less than 34 weeks gestational age and 1500 birth weight. However, further studies with larger sample sizes and longer follow-up periods are needed to confirm these results and assess long-term outcomes.

    支气管肺发育不良(BPD)是一个复杂的,影响早产新生儿的多因素肺部疾病,可导致长期肺部和非肺部并发症。目前的治疗主要集中在BPD发展后的症状管理,这表明需要创新的方法来预测和确定从有针对性或早期干预措施中获益最大的新生儿。临床信息学,生物医学信息学的一个子领域,正在通过将计算方法与患者数据集成来改善患者预后,从而改变医疗保健。通过利用电子健康记录数据,临床信息学在开发和增强BPD临床治疗方面的应用提供了机会。应用机器学习算法,实施临床决策支持系统。这篇综述强调了临床信息学在识别临床相关BPD表型和开发临床决策支持工具以改善发育或已建立BPD的极度早产新生儿的管理方面的当前障碍和未来潜力。然而,除非我们解决当前的挑战,如数据收集,storage,隐私,和固有的数据偏差。
    Bronchopulmonary dysplasia (BPD) is a complex, multifactorial lung disease affecting preterm neonates that can result in long-term pulmonary and non-pulmonary complications. Current therapies mainly focus on symptom management after the development of BPD, indicating a need for innovative approaches to predict and identify neonates who would benefit most from targeted or earlier interventions. Clinical informatics, a subfield of biomedical informatics, is transforming healthcare by integrating computational methods with patient data to improve patient outcomes. The application of clinical informatics to develop and enhance clinical therapies for BPD presents opportunities by leveraging electronic health record data, applying machine learning algorithms, and implementing clinical decision support systems. This review highlights the current barriers and the future potential of clinical informatics in identifying clinically relevant BPD phenotypes and developing clinical decision support tools to improve the management of extremely preterm neonates developing or with established BPD. However, the full potential of clinical informatics in advancing our understanding of BPD with the goal of improving patient outcomes cannot be achieved unless we address current challenges such as data collection, storage, privacy, and inherent data bias.

    坏死性小肠结肠炎(NEC)和脑室周围白质软化(PVL)是低出生体重(VLBW)早产儿中相对常见的疾病。然而,在当前的文献中,合并NEC和PVL患者的病例报告有限.我们报告了一例早产女性,胎龄为25周零5天,由于NEC而在紧急肠切除术后出现了颅内囊性病变。经颅超声和磁共振成像证实右侧大脑中动脉分布存在囊性PVL。一些观察性研究注意到自发性肠穿孔之间的关联,NEC外科,和囊性PVL的存在。当婴儿对NEC的医疗管理没有反应时,建议剖腹探查术切除坏死或穿孔的肠。然而,与接受药物治疗的婴儿相比,接受手术治疗的婴儿神经发育结局较差.接受手术的早产儿神经发育障碍的发病机制涉及功能失调的脑血管自动调节(CAR),这与导致神经元损伤的脑灌注的有害变化有关。早产儿,比如那些有NEC的人,不能适当调节脑灌注,在剖腹手术中,超过一半的早产儿可能存在CAR受损。受损的CAR导致脑灌注不良,从而增强神经元损伤,例如PVL。此病例还使人们意识到,通过具有成本效益的经颅超声检查,必须遵守NICU危重患者白质损伤的筛查方法。
    Necrotizing enterocolitis (NEC) and periventricular leukomalacia (PVL) are relatively common conditions in premature infants with low birth weight (VLBW). However, in the current literature, there are limited case reports of patients with concomitant NEC and PVL. We report a case of a premature female born at a gestational age of 25 weeks and five days who developed cystic intracranial lesions after emergent bowel resection due to NEC. Transcranial ultrasound and magnetic resonance imaging confirmed the presence of cystic PVL in the right middle cerebral artery distribution. Several observational studies note the association between spontaneous intestinal perforation, surgical NEC, and the presence of cystic PVL. When infants are unresponsive to medical management for NEC, exploratory laparotomy with resection of the necrotic or perforated intestine is indicated. However, infants treated surgically have poorer neurodevelopmental outcomes than those with medical therapy. Pathogenesis of neurodevelopmental impairment in preterm infants undergoing surgery involves dysfunctional cerebrovascular autoregulation (CAR), which is associated with harmful changes in cerebral perfusion that lead to neuronal injury. Ill preterm infants, such as those with NEC, cannot regulate cerebral perfusion appropriately, and impaired CAR may be present in more than half the preterm infants during laparotomy. Impaired CAR leads to poor cerebral perfusion that potentiates neuronal injury, such as PVL. This case also brings awareness to the need for adherence to screening practices for white matter injury in critical NICU patients through cost-effective transcranial ultrasound.

    我们介绍了一例在新生儿重症监护病房常规口服胃(OG)管放置后发生新生儿食管穿孔的病例。这是主要影响早产儿的罕见并发症,并且可能具有显着的发病率和死亡率。此病例显示了食管穿孔的初始影像学表现以及随后的影像学检查以确认诊断。还讨论了新生儿患者这种情况的临床管理。这种情况的独特亮点是与后来的研究相比,最初研究的放射线照相表现有所不同。
    We present a case of neonatal esophageal perforation following routine oral gastric (OG) tube placement in the neonatal intensive care unit. This is a rare complication primarily affecting premature infants and can have significant morbidity and mortality. This case demonstrates the initial radiographic presentation of esophageal perforation and the subsequent imaging to confirm the diagnosis. Clinical management of this condition in the neonatal patient is also discussed. A unique highlight of this case is the difference in radiographic presentation on the initial study as compared to the later study.

    背景:新的证据表明,N末端B型利钠肽原(NT-proBNP)在成人和儿童人群的多种心脏和肺部异常中的临床应用。迄今为止,然而,关于其对早产儿支气管肺发育不良的预测和严重程度的疗效尚无共识。本荟萃分析的目的是确定发生BPD或死于BPD的新生儿中NT-proBNP的差异,并评估该方法的诊断准确性是否有相关信息。
    方法:我们根据PRISMA指南进行了系统的搜索,并研究了Medline(1966-2023),Scopus(2004-2023),Clinicaltrials.gov(2008-2023),EMBASE(1980-2023),Cochrane中央对照试验登记册CENTRAL(1999-2022)和GoogleScholar(2004-2023)以及纳入研究的参考清单。使用QUADAS-2工具评估我们研究中遇到的潜在偏倚风险。最后,共有9项研究符合资格标准,包括1319名新生儿,其中397例发生BPD,922例未受影响的对照.
    结果:从我们的荟萃分析中获得的结果显示,与健康新生儿相比,患有BPD的新生儿出生后NT-proBNP水平明显升高(SMD2.57,95%CI0.41,4.72)。AUC荟萃分析的汇总效果显示,NT-proBNP在检测有严重BPD或死于该疾病的风险的新生儿方面非常准确(AUC-0.16,95%CI-0.23,-0.08)。没有研究报告与诊断BPD的方法的敏感性和/或特异性相关的数据。
    结论:血清NT-proBNP水平代表了一个潜在的未来生物标志物,对于预测BPD并发早产具有很大的诊断有效性。所包括的有限数量的研究以及截止值和测量时机的显著变化仍然限制了NT-proBNP作为BPD的已建立的临床生物标志物的应用。大型前瞻性研究的设计将提供更具代表性的参与者数量,并解决现有文献中的差异。
    BACKGROUND: Emerging evidence suggests the clinical utility of N terminal pro B type natriuretic peptide (NT-proBNP) in multiple cardiac and pulmonary abnormalities both in adult and pediatric populations. To date, however, there is no consensus regarding its efficacy for the prediction and severity of bronchopulmonary dysplasia in premature neonates. The objective of the present meta-analysis was to determine differences in NT-proBNP among neonates that develop BPD or die from BPD and to evaluate if there is relative information on the diagnostic accuracy of the method.
    METHODS: We conducted a systematic search according to the PRISMA guidelines and looked into Medline (1966-2023), Scopus (2004-2023), Clinicaltrials.gov (2008-2023), EMBASE (1980-2023), Cochrane Central Register of Controlled Trials CENTRAL (1999-2022) and Google Scholar (2004-2023) together with the reference lists from included studies. The potential risk of bias encountered in our study was evaluated using the QUADAS -2 tool. Finally, a total of 9 studies met the eligibility criteria, comprising 1319 newborns, from which 397 developed BPD and 922 were unaffected controls.
    RESULTS: The results retrieved from our meta-analysis showed that newborns suffering from BPD had notably elevated NT-proBNP levels after birth when compared with healthy neonates (SMD 2.57, 95% CI 0.41, 4.72). The summary effect of the AUC meta-analysis showed that NT-proBNP was very accurate in detecting neonates at risk of developing severe BPD or dying from the disease (AUC -0.16, 95% CI -0.23, -0.08). No studies reported data relevant to the sensitivity and/or specificity of the method in diagnosing BPD.
    CONCLUSIONS: Serum NT-proBNP levels represent a potential future biomarker with great diagnostic validity for the prediction of BPD complicating preterm deliveries. The limited amount of studies included and the significant variations in cutoff values and timing of measurement still restrict the application of NT-proBNP as an established clinical biomarker for BPD. The design of larger prospective studies will provide a more representative number of participants and will address the discrepancies in existing literature.

    UNASSIGNED:南非的新生儿死亡率低于全球平均水平,但仍比一些欧洲和斯堪的纳维亚国家高出约五倍。早产,和它的并发症,是新生儿死亡的主要原因(35%)。
    未经批准:要检查产妇,CharlotteMaxeke约翰内斯堡学术医院(CMJAH)的极低出生体重(VLBW)婴儿的分娩期和婴儿特征与死亡率的关系。
    UNASSIGNED:这是一项对2017年1月1日至2018年12月31日期间接受CMJAH的VLBW婴儿的回顾性描述性研究。包括所有出生体重在500至≤1,500克之间的婴儿。使用单变量分析描述了这些婴儿的特征和存活。
    未经授权:总生存率为66.5%。提供产前类固醇,产前保健,剖腹产,女性性别,出生时复苏,5分钟Apgar评分超过5分与更好的出院生存率相关。在呼吸道诊断中,82.8%被诊断为RDS,70.8%接受表面活性剂治疗,90.7%在复苏后接受无创呼吸支持。出院时,59.5%的母亲母乳喂养,30.8%的母亲在袋鼠母亲护理中度过了时间。
    UNASSIGNED:VLBW婴儿的三分之二存活率与其他发展中国家相似,但仍低于发达国家。这可以通过更好的产前护理得到改善,产前类固醇的覆盖率,出生后的温度控制,改善感染预防和控制措施,母乳喂养率和袋鼠母亲护理。极低出生体重(ELBW)婴儿的存活率最低。
    UNASSIGNED: The neonatal mortality rate in South Africa is lower than the global average, but still approximately five times higher than some European and Scandinavian countries. Prematurity, and its complications, is the main cause (35%) of neonatal deaths.
    UNASSIGNED: To review the maternal, delivery period and infant characteristics in relation to mortality in very low birth weight (VLBW) infants at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH).
    UNASSIGNED: This was a retrospective descriptive study of VLBW infants admitted to CMJAH between 1 January 2017 and 31 December 2018. All infants with a birth weight between 500 to ≤ 1,500 grams were included. The characteristics and survival of these infants were described using univariate analysis.
    UNASSIGNED: Overall survival was 66.5%. Provision of antenatal steroids, antenatal care, Cesarean section, female sex, resuscitation at birth, and 5-min Apgar score more than five was related with better survival to discharge. Among respiratory diagnoses, 82.8% were diagnosed with RDS, 70.8% received surfactant therapy and 90.7% received non-invasive respiratory support after resuscitation. At discharge, 59.5% of the mothers were breastfeeding and 30.8% spent time in kangaroo mother care.
    UNASSIGNED: The two-thirds survival rate of VLBW infants is similar to those in other developing countries but still remains lower than developed countries. This may be improved with better antenatal care attendance, coverage of antenatal steroids, temperature control after birth, improving infection prevention and control practices, breastfeeding rates and kangaroo mother care. The survival rate was lowest amongst extremely low birth weight (ELBW) infants.

    UNASSIGNED:有证据表明,在待命期间出生早产新生儿时,发病率和死亡率的风险更高。这项研究旨在评估这种情况在其他结果决定因素中的影响,特别是新生儿特征和护理组织。
    UNASSIGNED:观察性研究包括2007年至2020年在法国三级围产期中心出生<30周的所有婴儿。随叫随到时间对应于工作日下午6:30至上午8:30,周末,和公众假期。主要终点是无严重发病率的生存率,包括3-4级脑室内出血(IVH),囊性脑室周围白质软化,坏死性小肠结肠炎,重度支气管肺发育不良(BPD),和严重的早产儿视网膜病变.入院与结果之间的关系是通过调整后的优势比(aOR)对在通话期间出生的倾向进行评估的,并表示与工作日。二次分析在极早产新生儿(<27周妊娠)进行,在早期死亡(7天内)的情况下,之前(2007-2013年,占队列的51.5%)与在(2014-2020年,队列的48.5%)实施了一个致力于分娩室新生儿护理的儿科医生-护士团队之后.
    未经评估:总共1,064名婴儿[27.9(26.3;28.9)周,包括947(760;1,147)g]:待命期间为668(63%),工作日为396(37%)。对于平日出生的婴儿,无严重发病率的生存率为54.5%,死亡率为19.2%.在通话期间,这些比率分别为57.3%[aOR1.08(0.84-1.40)]和18.4%[aOR0.93(0.67-1.29)]。在极度早产儿中观察到无严重发病率[aOR1.42(0.87-2.34)]或死亡率[aOR0.76(0.47-1.22)]的生存率相当。平日的早期死亡率为6.4%,而不是在通话期间为8.2%[aOR1.44(0.84-2.48)]。专门小组的实施与死亡率[aOR0.57(0.38,0.85)]和3-4级IVH[aOR0.48(0.30,0.75)]下降有关,严重BPD的发生率增加[aOR2.16(1.37,3.41)],对于在待命期间出生的婴儿。
    未经评估:在此队列中,大多数早产新生儿的出生发生在待命期间。一个致力于分娩室新生儿护理的团队可能会对在这种情况下出生的婴儿的结局产生有利影响。
    UNASSIGNED: The evidence that risks of morbidity and mortality are higher when very premature newborns are born during the on-call period is inconsistent. This study aimed to assess the impact of this situation among other determinants of outcomes, particularly newborn characteristics and care organization.
    UNASSIGNED: Observational study including all infants born < 30 weeks\' gestation in a French tertiary perinatal center between 2007 and 2020. On-call period corresponded to weekdays between 6:30 p.m. and 8:30 a.m., weekends, and public holidays. The primary endpoint was survival without severe morbidity, including grade 3-4 intraventricular hemorrhage (IVH), cystic periventricular leukomalacia, necrotizing enterocolitis, severe bronchopulmonary dysplasia (BPD), and severe retinopathy of prematurity. The relationship between admission and outcome was assessed by an adjusted odds ratio (aOR) on the propensity of being born during on-call period and expressed vs. weekday. Secondary analyses were carried out in extremely preterm newborns (<27 weeks\' gestation), in cases of early death (within 7 days), and before (2007-2013, 51.5% of the cohort) vs. after (2014-2020, 48.5% of the cohort) the implementation of a pediatrician-nurse team dedicated to newborn care in the delivery room.
    UNASSIGNED: A total of 1,064 infants [27.9 (26.3; 28.9) weeks, 947 (760; 1,147) g] were included: 668 during the on-call period (63%) and 396 (37%) on weekdays. For infants born on weekdays, survival without severe morbidity was 54.5% and mortality 19.2%. During on-call, these rates were 57.3% [aOR 1.08 (0.84-1.40)] and 18.4% [aOR 0.93 (0.67-1.29)]. Comparable rates of survival without severe morbidity [aOR 1.42 (0.87-2.34)] or mortality [aOR 0.76 (0.47-1.22)] were observed in extremely preterm infants. The early death rate was 6.4% on weekdays vs. 8.2% during on-call [aOR 1.44 (0.84-2.48)]. Implementation of the dedicated team was associated with decreased rates of mortality [aOR 0.57 (0.38, 0.85)] and grade 3-4 IVH [aOR 0.48 (0.30, 0.75)], and an increased rate of severe BPD [aOR 2.16 (1.37, 3.41)], for infants born during on-call.
    UNASSIGNED: In this cohort, most births of very premature neonates occurred during the on-call period. A team dedicated to newborn care in the delivery room may have a favorable effect on the outcome of infants born in this situation.

    由黑色酵母样真菌皮肤Exophiala引起的全身性感染很少见,但与高死亡率相关,尤其是在免疫功能低下的患者中。我们报告了第一例早产极低出生体重(ELBW)的新生儿,尽管使用脂质体两性霉素(AMB)和氟康唑进行了抗真菌治疗,但该新生儿仍死亡。我们还对所有由E.dermatitidis引起的真菌血症病例进行了系统评价,目的是更好地了解风险因素。治疗策略和结果。
    一个男性,ELBW早产儿,在他出生后不久,出现了心动过缓,呼吸暂停,最终坏死性小肠结肠炎伴肠穿孔,需要手术干预。同时,他也有多种发生血流感染的危险因素,比如插管,机械通气,中心静脉导管(CVC),肠外营养,经验性和长期使用抗生素。他的血培养呈阳性,在氟康唑预防性治疗和抗生素经验性治疗期间,首先是朱氏不动杆菌,然后是肺炎克雷伯菌和柏林大肠杆菌。尽管用广谱抗生素治疗,脂质体AMB和氟康唑,新生儿死了。文献综述确定了另外12例E.dermatitidis血流感染,主要是血液系统恶性肿瘤和实体器官移植受者(61%),尽管CVC去除和抗真菌治疗,总死亡率为38%。
    由于E.dermatitidis感染的罕见,对这种酵母的特性知之甚少,鉴定方法和最佳治疗方法。通过常见的生化测试进行鉴定是有问题的,需要分子鉴定。尽管进行了适当的抗真菌治疗,但新生儿真菌血症的解决仍然很困难,尤其是在具有多种严重危险因素的情况下,例如目前的危险因素。治疗性干预可包括CVC去除和使用唑(药敏试验后伊曲康唑或氟康唑)或AMB单一疗法治疗至少3周,但不包括棘白菌素或AMB加唑联合疗法。
    Systemic infections caused by the black yeast-like fungus Exophiala dermatitidis are rare, but are associated with high mortality especially in immunocompromised patients. We report the first case of E. dermatitidis fungemia in a premature extremely low birth weight (ELBW) neonate who succumbed despite antifungal therapy with liposomal amphotericin (AMB) and fluconazole. A systematic review of all fungemia cases due to E. dermatitidis was also conducted aiming for a better understanding of the risk factors, treatment strategies and outcomes.
    A male, ELBW premature neonate, soon after his birth, developed bradycardia, apnoea and ultimately necrotizing enterocolitis with intestinal perforation requiring surgical intervention. Meanwhile, he had also multiple risk factors for developing bloodstream infection, such as intubation, mechanical ventilation, central venous catheter (CVC), parenteral nutrition, empirical and prolonged antibiotic use. His blood cultures were positive, firstly for Acinetobacter junii and then for Klebsiella pneumoniae together with E. dermatitidis while on fluconazole prophylaxis and antibiotic empiric therapy. Despite the treatment with broad spectrum antibiotics, liposomal AMB and fluconazole, the newborn succumbed. A literature review identified another 12 E. dermatitidis bloodstream infections, mainly in patients with hematologic malignancies and solid organ transplant recipients (61%), with overall mortality 38% despite CVC removal and antifungal therapy.
    Due to the rarity of E. dermatitidis infections, little is known about the characteristics of this yeast, the identification methods and the optimal therapy. Identification by common biochemical tests was problematic requiring molecular identification. Resolution of neonatal fungemia is difficult despite proper antifungal therapy especially in cases with multiple and severe risk factors like the present one. Therapeutic intervention may include CVC removal and treatment for at least 3 weeks with an azole (itraconazole or fluconazole after susceptibility testing) or AMB monotherapy but not echinocandins or AMB plus azole combination therapy.

    背景:实时剪切波弹性成像(SWE)对于定量评估组织和器官的硬度是非侵入性且可靠的。直到现在,很少有研究应用SWE评估早产儿的脑组织。这项研究试图比较新生儿的平均脑组织弹性模量(Emean)值的差异,并探讨影响这些差异的因素。
    方法:总共,以2019年12月至2021年2月收治的159名新生儿为研究对象,根据出生时间分为两组。早产儿,足月新生儿,和新生儿肺炎的新生儿被纳入这项研究。在159名新生儿中,76例早产,83例足月。SWE用于定量评估双侧室旁白质的Emean,丘脑,和脉络膜,分析两组新生儿体重指数(BMI)与Emeans的关系。
    结果:室旁白质的Emeans,丘脑,早产儿脉络膜低于足月新生儿(P<0.001)。早产儿和足月新生儿的BMI与双侧室旁白质呈正相关,丘脑,和脉络膜Emean.
    结论:SWE可用于定量评估新生儿的脑组织硬度,并作为新生儿脑部相关疾病的参考。
    BACKGROUND: Real-time shear wave elastography (SWE) is non-invasive and reliable for quantitatively evaluate stiffness of tissues and organs. Until now, little researches have applied SWE to evaluate brain tissue of premature neonates. This study sought to compare differences in the average brain tissue elasticity modulus (Emean) values of neonates, and explore the factors affecting these differences.
    METHODS: In total, 159 neonates admitted from December 2019 to February 2021 were taken as the study subjects and divided into 2 groups based on their time of birth. Premature neonates, full-term neonates, and neonates with neonatal pneumonia were included in this study. Of the 159 neonates, 76 were premature and 83 were full-term. SWE was used to quantitatively evaluate the Emean of bilateral paraventricular white matter, thalamus, and choroid, and to analyze the relationship between body mass index (BMI) and Emeans in both groups of neonates.
    RESULTS: The Emeans of the paraventricular white matter, thalamus, and choroid of the premature neonates were lower than those of the full-term neonates (P<0.001). The BMI of the premature and full-term neonates was positively correlated to the bilateral paraventricular white matter, thalamus, and choroid Emean.
    CONCLUSIONS: SWE can be used to quantitatively evaluate the brain tissue stiffness of neonates, and as a reference for neonatal brain-related diseases.
