    母体中枢亲神经性药物暴露后新生儿发病率的评估。
    2018年至2021年CND后新生儿的回顾性单中心III级新生儿学队列分析。对照组在产科病房照顾没有CND的母亲所生的新生儿。
    CND新生儿需要更频繁的治疗[OR23(95%CI:7.8-62);RR14(95%CI:5.4-37);p<0.01]。CND后新生儿的Apgar评分较低,LM1[CND8.1;CG8.6;p<0.05];LM5[CND9;CG9.7;p<0.01];LM10[CND9.6;CG9.9;p<0.05]。24h内首发症状占95.35%(平均3.3h)。CND组显示早产明显更频繁[OR3.5;RR3.2;p<0.05],尤其是累积的多种症状[OR9.4;RR6.6;p<0.01],但与母亲多次用药无关(p=0.3)。
    暴露于CND的新生儿产后治疗的风险增加,通常是由于多种症状。应连续监测新生儿至少24小时。
    Evaluation of neonatal morbidity after maternal central neurotropic drug exposure.
    Retrospective single-center level-III neonatology cohort analysis of neonates after CND from 2018 to 2021. Control group of neonates born to mothers without CND cared for at the maternity ward.
    Significantly more frequent therapy need of neonates with CND [OR 23 (95% CI: 7.8-62); RR 14 (95% CI: 5.4-37); p < 0.01]. Neonates after CND had lower Apgar-scores LM 1 [CND 8.1; CG 8.6; p < 0.05]; LM 5 [CND 9; CG 9.7; p < 0.01]; LM 10 [CND 9.6; CG 9.9; p < 0.05]. The first symptom occurred in 95.35% within 24 h (mean: 3.3 h). CND group showed significantly more often preterm delivery [OR 3.5; RR 3.2; p < 0.05], and especially cumulative multiple symptoms [OR 9.4; RR 6.6; p < 0.01] but no correlation to multiple maternal medication use (p = 0.3).
    Neonates exposed to CND are at increased risk for postnatal therapy, often due to multiple symptoms. Neonates should be continuously monitored for at least 24 h.

    背景:极早产儿,定义为28周胎龄之前出生的人,是一个非常脆弱的患者群体,面临不良后果的高风险,如坏死性小肠结肠炎和死亡。坏死性小肠结肠炎是一种炎症性胃肠道疾病,在该队列中发病率很高,对发病率和死亡率有严重影响。先前的随机对照试验表明,补充益生菌后,年龄较大的早产儿坏死性小肠结肠炎的发生率降低。然而,这些试验对极度早产儿的作用不足,迄今为止,该人群补充益生菌的证据不足。
    方法:斯堪的纳维亚极端早产益生菌(PEPS)试验是一个多中心,双盲,在瑞典6个三级新生儿病房和丹麦4个新生儿病房出生的极早产儿(n=1620)中进行了安慰剂对照和基于注册的随机对照试验.登记的婴儿将被分配接受ProPrems®(婴儿双歧杆菌,乳酸双歧杆菌,和嗜热链球菌)在3mL母乳中稀释,或每天在3mL母乳中稀释的安慰剂(0.5g麦芽糊精粉),直至妊娠第34周。主要复合结局是坏死性小肠结肠炎的发生率和/或死亡率。次要结果包括迟发性败血症的发生率,住院时间,使用抗生素,喂养耐受性,增长,足月年龄和出院后3个月校正年龄时的身体成分。
    结论:由于缺乏证据,目前瑞典和丹麦对益生菌补充剂的建议并不包括极度早产儿。然而,这一年轻亚组尤其是出现不良结局的风险最大.该试验旨在研究补充益生菌对坏死性小肠结肠炎的影响,死亡,和其他相关结果,以提供足够的动力,高质量的证据为该人群的益生菌补充指南提供信息。结果可能对瑞典和丹麦以及全世界的临床实践产生影响。
    背景:(Clinicaltrials.gov):NCT05604846。
    BACKGROUND: Extremely preterm infants, defined as those born before 28 weeks\' gestational age, are a very vulnerable patient group at high risk for adverse outcomes, such as necrotizing enterocolitis and death. Necrotizing enterocolitis is an inflammatory gastrointestinal disease with high incidence in this cohort and has severe implications on morbidity and mortality. Previous randomized controlled trials have shown reduced incidence of necrotizing enterocolitis among older preterm infants following probiotic supplementation. However, these trials were underpowered for extremely preterm infants, rendering evidence for probiotic supplementation in this population insufficient to date.
    METHODS: The Probiotics in Extreme Prematurity in Scandinavia (PEPS) trial is a multicenter, double-blinded, placebo-controlled and registry-based randomized controlled trial conducted among extremely preterm infants (n = 1620) born at six tertiary neonatal units in Sweden and four units in Denmark. Enrolled infants will be allocated to receive either probiotic supplementation with ProPrems® (Bifidobacterium infantis, Bifidobacterium lactis, and Streptococcus thermophilus) diluted in 3 mL breastmilk or placebo (0.5 g maltodextrin powder) diluted in 3 mL breastmilk per day until gestational week 34. The primary composite outcome is incidence of necrotizing enterocolitis and/or mortality. Secondary outcomes include incidence of late-onset sepsis, length of hospitalization, use of antibiotics, feeding tolerance, growth, and body composition at age of full-term and 3 months corrected age after hospital discharge.
    CONCLUSIONS: Current recommendations for probiotic supplementation in Sweden and Denmark do not include extremely preterm infants due to lack of evidence in this population. However, this young subgroup is notably the most at risk for experiencing adverse outcomes. This trial aims to investigate the effects of probiotic supplementation on necrotizing enterocolitis, death, and other relevant outcomes to provide sufficiently powered, high-quality evidence to inform probiotic supplementation guidelines in this population. The results could have implications for clinical practice both in Sweden and Denmark and worldwide.

    背景:围产期窒息是出生时无法维持正常呼吸。世界卫生组织指出,围产期窒息是发展中国家新生儿死亡的第三大原因,每年占新生儿死亡的23%。在全球和国家一级,已经努力降低新生儿死亡率,然而,埃塞俄比亚的窒息死亡率仍然很高(24%)。并且没有足够的研究来显示窒息新生儿的发病率和死亡率预测。建立有效的风险预测模型是改善新生儿窒息结局的重要策略之一。因此,这项研究将有助于通过容易获得的预测因素来筛查住院期间死亡率高的窒息新生儿.本研究旨在确定Felege-Hiwot综合专科医院新生儿重症监护病房的窒息新生儿的发病率并开发有效的死亡率预测模型。BahirDar,埃塞俄比亚。
    方法:回顾性随访研究于2017年9月1日至2021年3月31日在Felege-Hiwot综合专科医院进行。采用简单随机抽样方法选择774例新生儿,738人被审查。因为数据是次要的,它是通过清单收集的。通过表和图描述数据后,采用似然比检验建立p值<0.25的单变量和p值<0.05的多变量逐步回归预测模型。为了提高临床效用,我们建立了简化的风险评分,将窒息新生儿的死亡率高或低.使用曲线下面积评估模型的准确性,和校准图。为了测量所有准确性,使用自举技术评估了内部验证。我们使用各种阈值概率的决策曲线分析评估了模型的临床影响。
    结果:新生儿窒息死亡率为27.2%(95%CI:24.1,30.6)。农村住宅,不良产科史,羊水状态,多胎妊娠,出生体重(<2500克),缺氧缺血性脑病(II期和III期),在最终的风险预测评分中确定了未能吸吮。使用7个预测因子的死亡率曲线下面积为0.78(95%CI0.74至0.82)。在≥7个截止值的情况下,风险预测评分的敏感性和特异性分别为0.64和0.82。
    结论:新生儿窒息死亡率高。风险预测得分具有良好的农村居民点鉴别力,不良产科史,羊水染色,多胎妊娠,出生体重(<2500克),缺氧缺血性脑病(II期和III期),失败了。因此,使用此评分图并改善新生儿和孕产妇服务可降低窒息新生儿的死亡率。
    BACKGROUND: Perinatal asphyxia is failure to maintain normal breathing at birth. World Health Organization indicates that perinatal asphyxia is the third major cause of neonatal mortality in developing countries accounting for 23% of neonatal deaths every year. At global and national level efforts have done to reduce neonatal mortality, however fatalities from asphyxia remains high in Ethiopia (24%). And there are no sufficient studies to show incidence and prediction of mortality among asphyxiated neonates. Developing validated risk prediction model is one of the crucial strategies to improve neonatal outcomes with asphyxia. Therefore, this study will help to screen asphyxiated neonate at high-risk for mortality during admission by easily accessible predictors. This study aimed to determine the incidence and develop validated Mortality Prediction model among asphyxiated neonates admitted to the Neonatal Intensive Care Unit at Felege-Hiwot Comprehensive Specialized Hospital, Bahir Dar, Ethiopia.
    METHODS: Retrospective follow-up study was conducted at Felege-Hiwot Comprehensive Specialized Hospital from September 1, 2017, to March 31, 2021. Simple random sampling was used to select 774 neonates, and 738 were reviewed. Since was data Secondary, it was collected by checklist. After the description of the data by table and graph, Univariable with p-value < 0.25, and stepwise multivariable analysis with p-value < 0.05 were done to develop final reduced prediction model by likelihood ratio test. To improve clinical utility, we developed a simplified risk score to classify asphyxiated neonates at high or low-risk of mortality. The accuracy of the model was evaluated using area under curve, and calibration plot. To measures all accuracy internal validation using bootstrapping technique were assessed. We evaluated the clinical impact of the model using a decision curve analysis across various threshold probabilities.
    RESULTS: Incidence of neonatal mortality with asphyxia was 27.2% (95% CI: 24.1, 30.6). Rural residence, bad obstetric history, amniotic fluid status, multiple pregnancy, birth weight (< 2500 g), hypoxic-ischemic encephalopathy (stage II and III), and failure to suck were identified in the final risk prediction score. The area under the curve for mortality using 7 predictors was 0.78 (95% CI 0.74 to 0.82). With ≥ 7 cutoffs the sensitivity and specificity of risk prediction score were 0.64 and 0.82 respectively.
    CONCLUSIONS: Incidence of neonatal mortality with asphyxia was high. The risk prediction score had good discrimination power built by rural residence, bad obstetric history, stained amniotic fluid, multiple pregnancy, birth weight (< 2500 g), hypoxic-ischemic encephalopathy (stage II and III), and failure to suck. Thus, using this score chart and improve neonatal and maternal service reduce mortality among asphyxiated neonates.

    新生儿死亡率(NMR)定义为每1,000名活产婴儿在生命的前28天死亡的概率。在妊娠结束时没有危险因素的新生儿死亡可能是分娩期间和生病新生儿护理质量欠佳的指标。因此,这项研究的目的是确定在产前期间未发现风险的新生儿死亡发生的相关因素。
    2017年至2021年进行了一项横断面研究。招募的孕妇是那些有生命的人,term,在开始分娩时没有检测到胎儿异常的单次宫内妊娠。通过在片剂中的kobo工具中定制的开放式数据试剂盒(ODK)形式收集数据。使用STATA统计软件进行数据分析。对与新生儿死亡率相关的因素进行了多因素logistic回归分析,如果p<0.05,则认为有意义。
    在4401名注册母亲中,新生儿死亡人数为361人(8.2%)。产前无危险因素新生儿死亡的相关因素为低Apgar评分[AOR=4.38:95CI(2.33-7.72)],男性[AOR=2.25:95CI(1.12-3.81)],胎龄大于40周[AOR=4.79:(2.50-7.61)]和辅助阴道分娩[AOR=2.55:95CI(1.12-4.96)].
    新生儿死亡人数的增加与新生儿的性别有关,阿普加得分低,成熟后和辅助阴道分娩。应进行基于医院的研究,以解决可预防的新生儿死亡,在出生前没有检测到危险因素。
    UNASSIGNED: neonatal mortality rate (NMR) is defined as the probability of dying during the first 28 days of life expressed per 1,000 live births. The death of neonates without risk factors at the end of pregnancy could be an indicator of sub-optimal quality care during labor and care of sick neonates. Therefore, this study aimed to determine the factors associated with neonatal deaths happening without detected risks during prenatal period.
    UNASSIGNED: a cross-sectional study was conducted from 2017 to 2021.The recruited pregnant women were those who had a live, term, single-intrauterine pregnancy without detectable fetal abnormality at the time of starting labor. The data were collected through open data kit (ODK) forms that were customized in kobo tool in the tablets. The data analysis was performed using STATA statistical software. The factors associated with neonatal mortality were analyzed in a multiple logistic regression and considered significant if p < 0.05.
    UNASSIGNED: among the 4401 enrolled mothers, neonatal deaths were 361 (8.2%). The factors associated with death of neonates without risk factors during prenatal period were low Apgar score [AOR = 4.38: 95%CI (2.33-7.72)], male sex [AOR=2.25: 95%CI (1.12-3.81)], gestational age above 40 weeks [AOR=4.79: (2.50-7.61)] and assisted vaginal delivery [AOR = 2.55: 95%CI (1.12-4.96)].
    UNASSIGNED: the increased number of neonatal deaths are associated with sex of neonates, low Apgar score, post maturity and assisted vaginal delivery. The hospital-based studies should be done to address the preventable neonatal deaths with no detected risk factors before birth.

    背景:孕早期营养状况可能与不良分娩结局相关,如小于胎龄儿(SGA)和低出生体重(LBW)。BMI(身体质量指数)和MUAC(中上臂围)易于使用的评估,并且如果在孕早期获得,则表明孕前营养状况。这项研究主要在基于社区的巴基斯坦妇女队列中使用BMI和MUAC与SGA评估产妇营养状况的关联。它还旨在确定MUAC和BMI在预测SGA中的预测能力。其次,我们评估了孕妇营养与大于胎龄(LGA)和LBW之间的关系.
    方法:这项研究是对IbrahimHyderi和RehriGoth正在进行的妊娠队列“妊娠风险婴儿监测和测量联盟(PRISMA)”的二次分析,卡拉奇.在2021年1月至2022年8月之间招募的PRISMA参与者被纳入,因为他们的胎龄<14周,通过超声确认。MUAC和BMI测量是可用的,出生体重在72小时内被捕获。使用多变量逻辑回归来确定孕妇营养状况与SGA之间的关联。PRISMA研究获得了阿加汗大学伦理审查委员会的批准(2021-5920-15,518)。
    结果:在分析中包括的926名女性中,26.6%(n=247)的MUAC较低(<23cm),而18.4%(n=171)的体重不足(BMI<18.5kg/m2)。近三分之一的低MUAC和体重不足的妇女分娩了SGA婴儿(分别为34.4%和35.1%)。体重过重的女性和MUAC低的女性与SGA(体重过重:OR1.49,95%CI1.1,2.4;低MUAC-OR1.64,95%CI1.2,2.3)以及LBW(体重过轻:OR-1.63,95%CI1.1,2.4;低MUAC-OR-1.63,95%CI1.2,2.3)具有统计学意义。ROC曲线显示MUAC和BMI对SGA具有适度的可预测性(AUC<0.7)。
    结论:BMI和MUAC显示的产妇营养状况与不良妊娠结局密切相关,包括SGA,LGA和LBW。尽管MUAC和BMI被广泛用于确定产妇的营养状况,他们对新生儿大小的预测能力较差。需要进一步的研究来确定其他工具或工具的组合,以更好地预测资源有限的环境和计划干预措施中的不良出生结局。
    BACKGROUND: Early pregnancy nutritional status can be associated with adverse birth outcomes such as small-for-gestational age (SGA) and low birth weight (LBW). BMI (Body Mass Index) and MUAC (Mid-upper arm circumference) are easy to use assessments and are indicative of the pre-pregnancy nutritional status if obtained in the first trimester. This study primarily assesses the association of maternal nutritional status using BMI and MUAC with SGA in a community-based cohort of Pakistani women. It also aims to determine the predictive ability of MUAC and BMI in predicting SGA. Secondarily, we assessed the association between maternal nutrition and large for gestational age (LGA) and LBW.
    METHODS: This study is a secondary analysis of an ongoing pregnancy cohort \"Pregnancy Risk Infant Surveillance and Measurement Alliance (PRISMA)\"in Ibrahim Hyderi and Rehri Goth, Karachi. PRISMA participants who were enrolled between January 2021 to August 2022 were included given they had a gestational age < 14 weeks confirmed via ultrasound, MUAC and BMI measurements were available and birth weight was captured within 72 hours. Multivariable logistic regression was used to determine an association between maternal nutritional status and SGA. The PRISMA study was approved by the Aga Khan University Ethics Review Committee (2021-5920-15,518).
    RESULTS: Of 926 women included in the analysis, 26.6% (n = 247) had a low MUAC (< 23 cm) while 18.4% (n = 171) were underweight (BMI < 18.5 kg/m2). Nearly one third of low MUAC and underweight women delivered SGA infants (34.4 and 35.1% respectively). Underweight women and women with low MUAC had a statistically significant association with SGA (Underweight: OR 1.49, 95% CI 1.1,2.4; Low MUAC-OR 1.64, 95% CI 1.2,2.3) as well as LBW (Underweight: OR-1.63, 95% CI 1.1,2.4; Low MUAC-OR-1.63, 95% CI 1.2,2.3). ROC curves showed that MUAC and BMI had modest predictability for SGA (AUC < 0.7).
    CONCLUSIONS: Maternal nutritional status as indicated by BMI and MUAC are strongly associated with adverse pregnancy outcomes including SGA, LGA and LBW. Although MUAC and BMI are widely used to determine maternal nutritional status, they have poor predictive ability for newborn size. Further research is needed to identify other tools or a combination of tools to better predict adverse birth outcomes in resource-limited settings and plan interventions.

    新生儿脑病(NE)是受影响婴儿终身残疾和神经系统并发症的主要原因。在该人群中识别新的诊断生物标志物可能有助于预测MRI损伤,并将NE新生儿与低脐带pH值或健康新生儿区分开来,并可能帮助临床医生做出实时决策。比较NE新生儿的microRNA(miRNA)谱,健康的控制,和低脐带pH的新生儿。此外,将miRNA浓度与NE新生儿的脑损伤严重程度进行比较。这是对来自佛罗里达大学健康盖恩斯维尔大学生物储存库和数据注册表中的选定样品的miRNA谱的回顾性分析。FireflymiRNA分析用于筛选NE新生儿(n=36)中总共65个神经miRNA靶标,低脐带pH(n=18)和健康对照(n=37)。多元统计技术,包括主成分分析和正交偏最小二乘判别分析,和miRNA富集分析和注释用于鉴定miRNA标记及其病理生物学相关性。鉴定了一组10个高度有影响力的miRNAs,与健康对照组相比,NE组显著上调。其中,miR-323a-3p和mir-30e-5p显示表达水平的最高倍数变化。此外,miR-34c-5p,miR-491-5p,和miR-346在NE组中显著高于低脐带pH组。此外,如通过MRI测量的,鉴定了可以区分NE组中的无/轻度和中度/重度损伤的若干miRNA。MiRNAs代表了改善NE管理的有前途的诊断和预后工具。
    Neonatal Encephalopathy (NE) is a major cause of lifelong disability and neurological complications in affected infants. Identifying novel diagnostic biomarkers in this population may assist in predicting MRI injury and differentiate neonates with NE from those with low-cord pH or healthy neonates and may help clinicians make real-time decisions. To compare the microRNA (miRNA) profiles between neonates with NE, healthy controls, and neonates with low cord pH. Moreover, miRNA concentrations were compared to brain injury severity in neonates with NE. This is a retrospective analysis of miRNA profiles from select samples in the biorepository and data registry at the University of Florida Health Gainesville. The Firefly miRNA assay was used to screen a total of 65 neurological miRNA targets in neonates with NE (n = 36), low cord pH (n = 18) and healthy controls (n = 37). Multivariate statistical techniques, including principal component analysis and orthogonal partial least squares discriminant analysis, and miRNA Enrichment Analysis and Annotation were used to identify miRNA markers and their pathobiological relevance. A set of 10 highly influential miRNAs were identified, which were significantly upregulated in the NE group compared to healthy controls. Of these, miR-323a-3p and mir-30e-5p displayed the highest fold change in expression levels. Moreover, miR-34c-5p, miR-491-5p, and miR-346 were significantly higher in the NE group compared to the low cord pH group. Furthermore, several miRNAs were identified that can differentiate between no/mild and moderate/severe injury in the NE group as measured by MRI. MiRNAs represent promising diagnostic and prognostic tools for improving the management of NE.

    背景:引起新生儿败血症的细菌对常用抗生素的耐药性增加。抗菌素耐药性是一个重大的全球健康问题。多药耐药生物体(MDROs)的传播与较高的发病率和死亡率有关。本研究旨在确定新生儿重症监护病房(NICU)发生MDRO新生儿败血症的危险因素。dr.拉梅兰海军中心医院,2020-2022年。
    方法:对113例符合条件的新生儿进行了横断面研究。选择血液培养细菌生长阳性并诊断为败血症的患者作为研究样品。采用单因素和多因素分析和多因素多因素多因素多因素回归分析新生儿发生多药耐药菌败血症的相关危险因素。<0.05的p值被认为是显著的。
    结果:多重耐药菌是新生儿败血症的主要病因(91/113,80.5%)。发生MDRO新生儿败血症的重要危险因素是较低的出生体重(OR:1.607,95%CI:1.003-2.576,p值:0.049),胎膜早破病史(ProM)≥18(OR:3.333,95%CI:2.047-5.428,p值<0.001),羊水粪染(OR:2.37,95%CI:1.512-3.717,p值<0.001),住院时间更长(OR:5.067,95%CI:2.912-8.815,p值<0.001),较低的Apgar评分(OR:2.25,95%CI:1.442-3.512,p值<0.001),以及呼吸支持设备的使用,例如有创通气(OR:2.687,95%CI:1.514-4.771,p值<0.001),和无创通气(OR:2,95%CI:1.097-3.645,p值:0.024)。
    结论:我们的研究确定了多药耐药菌新生儿败血症的各种危险因素,并强调需要改进感染控制实践,以减少现有的耐药脓毒症负担。低出生体重,母亲有超过18小时的胎膜早破病史,羊水胎粪污染,住院时间更长,阿普加分数很低,呼吸机的使用是耐药新生儿败血症发生的危险因素。
    BACKGROUND: Bacterial organisms causing neonatal sepsis have developed increased resistance to commonly used antibiotics. Antimicrobial resistance is a major global health problem. The spread of Multidrug-Resistant Organisms (MDROs) is associated with higher morbidity and mortality rates. This study aimed to determine the risk factors for developing MDRO neonatal sepsis in the Neonatal Intensive Care Unit (NICU), dr. Ramelan Navy Central Hospital, in 2020-2022.
    METHODS: A cross-sectional study was performed on 113 eligible neonates. Patients whose blood cultures were positive for bacterial growth and diagnosed with sepsis were selected as the study sample. Univariate and multivariate analysis with multiple logistic regression were performed to find the associated risk factors for developing multidrug-resistant organism neonatal sepsis. A p-value of < 0.05 was considered significant.
    RESULTS: Multidrug-resistant organisms were the predominant aetiology of neonatal sepsis (91/113, 80.5%). The significant risk factors for developing MDRO neonatal sepsis were lower birth weight (OR: 1.607, 95% CI: 1.003 - 2.576, p-value: 0.049), history of premature rupture of the membrane (ProM) ≥ 18 (OR: 3.333, 95% CI: 2.047 - 5.428, p-value < 0.001), meconium-stained amniotic fluid (OR: 2.37, 95% CI: 1.512 - 3.717, p-value < 0.001), longer hospital stays (OR: 5.067, 95% CI: 2.912 - 8.815, p-value < 0.001), lower Apgar scores (OR: 2.25, 95% CI: 1.442 - 3.512, p-value < 0.001), and the use of respiratory support devices, such as invasive ventilation (OR: 2.687, 95% CI: 1.514 - 4.771, p-value < 0.001), and non-invasive ventilation (OR: 2, 95% CI: 1.097 - 3.645, p-value: 0.024).
    CONCLUSIONS: Our study determined various risk factors for multidrug-resistance organism neonatal sepsis and underscored the need to improve infection control practices to reduce the existing burden of drug-resistant sepsis. Low-birth-weight, a maternal history of premature rupture of the membrane lasting more than 18 hours, meconium-stained amniotic fluid, longer hospital stays, a low Apgar score, and the use of ventilators were the risk factors for developing drug-resistant neonatal sepsis.

    METHODS: Cases were identified from a prospective multicenter study including patients aged 0-3 months with Group B Streptococcal (GBS) or Escherichia coli culture positive sepsis/meningitis. CSF CXCL10, MDC, IL-6, IL-8, IL-10, TNF- α, MIF, IL-1RA, CXCL13, IL-1β, CRP and procalcitonin concentrations were measured with Luminex technology.
    RESULTS: In 61/373 patients (17%) residual CSF from the lumbar puncture was available, of whom 16 (26%) had definitive meningitis, 15 (25%) probable meningitis and 30 (49%) had sepsis. All biomarkers were detectable in CSF and showed significantly higher concentrations in definitive meningitis versus sepsis patients and six biomarkers in probable meningitis versus sepsis patients. Discrimination between definitive meningitis and sepsis was excellent for IL-1RA (area under the receiver operating characteristic curve [AUC] 0.93), TNF-α (AUC 0.92), CXCL10 (AUC 0.90), IL-1β (AUC 0.92), IL-6 (AUC 0.94), IL-10 (AUC 0.93) and a combination of IL-1RA, TNF-α, CXCL-10 and CSF leukocyte count (AUC 0.95). CSF leukocyte count remained the predictor with the highest diagnostic accuracy (AUC 0.96).
    CONCLUSIONS: CSF inflammatory markers can be used to differentiate between neonatal sepsis and meningitis.

  • 文章类型: Journal Article
    目的:研究患者适应症或授精方案的异质性对早期抢救ICSI(rICSI)治疗后单胎新生儿结局的影响。
    方法:进行回顾性研究。使用倾向得分匹配和多变量逻辑回归来校正混杂因素和偏差。
    结果:总共9095例IVF患者,2063例ICSI患者,本研究纳入了642例早期rICSI患者。与未匹配和匹配的IVF组相比,早期rICSI患者的胎龄小(SGA)增加,新生儿结局无差异,风险比(RR)为1.31(95%CI:1.05,1.64)和1.49(95%CI:1.05,2.12)。进一步的分析表明,与不匹配和匹配的IVF患者相比,部分受精失败(PFF)周期的SGA显着增加,RRs分别为1.56(95%CI:1.08,2.27)和1.78(95%CI:1.22,2.59)。在PFF患者中,通过IVF的受精率与出生体重z评分之间呈正相关。
    结论:完全受精失败(TFF)患者的早期rICSI在新生儿结局方面似乎是安全的。然而,当将rICSI的适应症扩展到PFF患者时,后代的SGA增加了,表明对长期健康的潜在影响。由于其他治疗选择,例如仅使用IVF来源的胚胎仍然存在于这些患者中,需要进一步的研究来确认这些患者的最佳决策.
    OBJECTIVE: To investigate the impact of heterogeneity in patient indications or insemination protocols on neonatal outcomes of singletons following early rescue ICSI (rICSI) treatments.
    METHODS: A retrospective study was conducted. Propensity score matching and multivariable logistic regression were used to adjust for confounders and biases.
    RESULTS: A total of 9095 IVF patients, 2063 ICSI patients, and 642 early rICSI patients were included in the study. No differences were detected in neonatal outcomes except small for gestational age (SGA) which increased in early rICSI patients compared with both unmatched and matched IVF groups with the risk ratio (RR) of 1.31 (95% CI: 1.05, 1.64) and 1.49 (95% CI: 1.05, 2.12). Further analysis showed that SGA increased significantly in partial fertilization failure (PFF) cycles with RRs of 1.56 (95% CI: 1.08, 2.27) and 1.78 (95% CI: 1.22, 2.59) compared with both unmatched and matched IVF patients but not in TFF patients. A positive association between fertilization rate via IVF and birth weight z-score was revealed in the PFF patients.
    CONCLUSIONS: Early rICSI in patients with total fertilization failure (TFF) appeared to be safe in terms of neonatal outcomes. However, when expanding the indications of rICSI to PFF patients, the SGA in the offspring increased, suggesting a potential effect on long-term health. Since other treatment options, such as using only the IVF-origin embryos still exist for these patients, further studies were needed to confirm the optimal decision for these patients.
