    背景:这项研究探讨了奥里萨邦农村地区的新生儿护理和婴儿喂养实践,特别关注奥里萨邦的KBK+农村地区(卡拉汉迪-博兰吉尔-科拉普特地区),主要由附表部落和附表种姓个人居住。最近这些地区的健康指标有所改善。在这些地区健康指标改善的背景下,这项研究探讨了当前和不断变化的新生儿护理实践,并试图深入了解人们对导致这些变化的因素的看法。
    方法:这项定性研究于2023年2月至7月在基督教医院进行,奥里萨邦的Bissamcuttack。该方法涉及与母亲和祖母进行重点小组讨论。
    结果:分析显示健康的做法,如纯母乳喂养,直到6个月大,第一次洗澡的适当时机,并促进母亲对轻微疾病的医疗寻求行为。在婴儿的眼睛中使用牛酥油或母乳,灰在脐带上的应用,过去祖母更多地使用草药治疗小病,在母亲中不那么受欢迎。值得注意的是,母亲和祖母都实行了抵御“邪恶之眼”的文化习俗。尽管传统文化习俗对社区的信仰和规范产生了影响,这项研究发现了寻求健康行为的转变,增加对医疗保健提供者和安全医疗保健实践的依赖。该研究确定了认可的社会健康活动家(ASHA)作为农村社区和医疗保健系统之间的桥梁的关键作用。
    结论:这项研究为医疗保健提供者提供了有价值的见解,旨在加强农村地区以社区为中心的安全新生儿护理实践。重点是了解当前和不断变化的当地做法的重要性。这将有助于医疗保健提供者鼓励健康做法,同时通过ASHA和Anganwadi工人等社区工作者消除与新生儿护理相关的有害做法。
    BACKGROUND: This study delves into newborn care and infant-feeding practices in rural Odisha, specifically focusing on the rural KBK + region of Odisha (Kalahandi-Bolangir-Koraput region), inhabited predominantly by Schedule Tribes and Schedule Castes individuals. There has been an improvement in the health indicators in these areas in recent times. In the background of improved health indicators in these areas, this research explores the current and changing newborn care practices and attempts to gain insight into people\'s perceptions of the factors that brought about the changes.
    METHODS: This qualitative study was conducted between February and July 2023 at Christian Hospital, Bissamcuttack in Odisha. The methodology involved focused group discussions with mothers and grandmothers.
    RESULTS: Analysis revealed healthy practices like exclusive breastfeeding till six months of age, appropriate timing of the first bath, and prompt healthcare-seeking behavior for minor illnesses among the mothers. The use of cow ghee or breast milk in a baby\'s eyes, the application of ash on the umbilical cord, and the use of herbal medicines for minor illnesses were practiced more by the grandmothers in the past and were not as popular among the mothers. It is noteworthy that the cultural practices to ward off the \'evil eye\' were practiced by both mothers and grandmothers alike. Despite the influence of traditional cultural practices on the beliefs and norms of the community, the study identified a shift in health-seeking behavior, with increased reliance on healthcare providers and safe healthcare practices. The study identifies the pivotal role of Accredited Social Health Activists (ASHAs) as a bridge between the rural communities and the healthcare system.
    CONCLUSIONS: This research provides valuable insights for healthcare providers aiming to enhance community-centric safe newborn care practices in rural settings. The emphasis is on the importance of understanding the current and changing local practices. This would help the healthcare providers to encourage healthy practices while eliminating the harmful practices related to newborn care through community workers like ASHA and Anganwadi workers.

    全球融资基金(GFF)于2015年启动,以促进增加的国内外生殖融资,母性,新生,孩子,青少年健康,和营养。在这个连续过程中,一半的死亡是新生儿死亡,死产或孕产妇死亡;然而,这些主题在整个连续体中获得的援助资金最少。
    对孕产妇和新生儿健康(MNH)进行政策内容分析,包括死产,在GFF国家规划文件中,并评估与投资相关的死亡率负担。
    对24份GFF政策文件进行了内容分析,投资案例和项目评估文件(PAD),来自11个非洲国家。我们使用了一种系统的数据提取方法,并应用了一个考虑心态的分析框架,措施,以及用于MNH干预的资金,并提及死亡率结果。我们按国家比较了PAD投资与MNH相关的死亡。
    对于这11个国家,通过PAD分配了18.94亿美元的新资金,包括GFF的3.03亿美元(16%)。所有文件都对MNH有很强的内容,特别关注怀孕和分娩干预措施。投资案例通常包括全面的结果框架,而PAD的技术含量一般较少,指标较少。提到了死亡率结果,尤其是对母亲来说。死胎很少被列为目标。各国对供资描述有不同的方法。PAD分配与负担相称。
    GFF国家计划为解决MNH提供了一个有希望的开端。强调投资和负担之间的联系,明确包括死产,突出高影响力的一揽子计划,在适当的情况下,可能会增加影响。
    主要发现:孕产妇和新生儿保健一揽子计划被大力纳入全球融资基金11个非洲国家的政策文件,特别是关于怀孕和分娩,虽然死产较少,或产后护理,或者小而生病的新生儿护理。增加知识:本研究是全球融资基金投资案例和相关项目评估文件的首次独立内容分析,在文件中揭示了孕产妇和新生儿健康的基本一致内容,以及国家死亡负担与承诺投资之间的总体相关性。全球卫生对政策和行动的影响:全球融资机制已显示出对孕产妇和新生儿健康的有希望的初始投资,尽管也有加强的机会,特别是一些新生儿高影响包裹和计数对死胎的影响。
    UNASSIGNED: The Global Financing Facility (GFF) was launched in 2015 to catalyse increased domestic and external financing for reproductive, maternal, newborn, child, adolescent health, and nutrition. Half of the deaths along this continuum are neonatal deaths, stillbirths or maternal deaths; yet these topics receive the least aid financing across the continuum.
    UNASSIGNED: To conduct a policy content analysis of maternal and newborn health (MNH), including stillbirths, in GFF country planning documents, and assess the mortality burden related to the investment.
    UNASSIGNED: Content analysis was conducted on 24 GFF policy documents, investment cases and project appraisal documents (PADs), from 11 African countries. We used a systematic data extraction approach and applied a framework for analysis considering mindset, measures, and money for MNH interventions and mentions of mortality outcomes. We compared PAD investments to MNH-related deaths by country.
    UNASSIGNED: For these 11 countries, USD$1,894 million of new funds were allocated through the PADs, including USD$303 million (16%) from GFF. All documents had strong content on MNH, with particular focus on pregnancy and childbirth interventions. The investment cases commonly included comprehensive results frameworks, and PADs generally had less technical content and fewer indicators. Mortality outcomes were mentioned, especially for maternal. Stillbirths were rarely included as targets. Countries had differing approaches to funding descriptions. PAD allocations are commensurate with the burden.
    UNASSIGNED: The GFF country plans present a promising start in addressing MNH. Emphasising links between investments and burden, explicitly including stillbirth, and highlighting high-impact packages, as appropriate, could potentially increase impact.
    Main finding: Maternal and newborn health care packages are strongly included in the Global Financing Facility policy documents for 11 African countries, especially regarding pregnancy and childbirth, though less for stillbirth, or postnatal care, or small and sick newborn care.Added knowledge: This study is the first independent content analysis of Global Financing Facility investment cases and related project appraisal documents, revealing mostly consistent content for maternal and newborn health across documents and overall correlation between national mortality burden and investments committed.Global health impact for policy and action: The Global Financing Facility have demonstrated promising initial investments for maternal and newborn health, although there are also missed opportunities for strengthening, especially for some neonatal high-impact packages and counting impact on stillbirths.

    胎儿生长受限(FGR)影响5%-10%的妊娠,并且与死亡率和发病率的增加的风险相关。尽管在多达50%的FGR婴儿中观察到不利的神经发育结果,FGR的诊断并不表明个别婴儿的风险水平,因此这些婴儿不接受常规随访以评估神经发育结局.确定FGR婴儿的神经发育不良结局风险增加将大大有助于早期提供适当的支持和干预措施。从而改善结果。然而,目前检测出生前后脑损伤的方法缺乏检测与FGR相关的更细微改变所需的灵敏度。血液生物标志物具有这种潜力。本系统综述评估了目前关于血液生物标志物的文献,用于识别出生后>12个月的不良神经发育结局风险增加的FGR婴儿。从开始到2024年2月22日搜索了四个数据库。两名审稿人评估了文章是否符合纳入标准。使用诊断准确性研究质量评估2评估纳入的文章的质量。由于确定的荟萃分析文章不足,因此提供了研究结果的摘要。排除重复项,筛选了1,368条记录,只有9篇文章考虑进行全文审查。只有一篇文章符合所有纳入标准。质量评估表明偏倚风险较低。在这项研究中调查了两种血液生物标志物,神经元特异性烯醇化酶和S100B,在2年时证明与神经发育评估呈负相关。四项研究不符合所有纳入标准,但确定了代谢物和细胞因子的有希望的发现,在这里讨论。这些发现支持了进一步研究的需要,并强调了血液生物标志物预测不良后果的潜力。

    Fetal growth restriction (FGR) impacts 5%-10% of pregnancies and is associated with increased risk of mortality and morbidity. Although adverse neurodevelopmental outcomes are observed in up to 50% of FGR infants, a diagnosis of FGR does not indicate the level of risk for an individual infant and these infants are not routinely followed up to assess neurodevelopmental outcomes. Identifying FGR infants at increased risk of adverse neurodevelopmental outcomes would greatly assist in providing appropriate support and interventions earlier, resulting in improved outcomes. However, current methods to detect brain injury around the time of birth lack the sensitivity required to detect the more subtle alterations associated with FGR. Blood biomarkers have this potential. This systematic review assessed the current literature on blood biomarkers for identifying FGR infants at increased risk of adverse neurodevelopmental outcomes at >12 months after birth. Four databases were searched from inception to 22 February 2024. Articles were assessed for meeting the inclusion criteria by two reviewers. The quality of the included article was assessed using Quality Assessment of Diagnostic Accuracy Studies-2. A summary of findings is presented as insufficient articles were identified for meta-analysis. Excluding duplicates, 1,368 records were screened with only 9 articles considered for full text review. Only one article met all the inclusion criteria. Quality assessment indicated low risk of bias. Both blood biomarkers investigated in this study, neuron specific enolase and S100B, demonstrated inverse relationships with neurodevelopmental assessments at 2 years. Four studies did not meet all the inclusion criteria yet identified promising findings for metabolites and cytokines which are discussed here. These findings support the need for further research and highlight the potential for blood biomarkers to predict adverse outcomes.

    输液外渗在新生儿中的发生率增加,这可能导致各种不良后果。本研究旨在探讨不同气质类型对新生儿输液外渗的影响。使用新生儿行为评估量表评分(NBAS)对209例接受输液治疗的4-7天新生儿进行气质类型评估。使用2009年输液护士协会外渗的临床分级标准,以及新生儿的临床数据,例如胎龄和体重,被收集。在接受评估的209名新生儿中,107出现输液外渗,发病率为51.2%。中等气质类型的新生儿更容易发生输液外渗。体重低的新生儿,羊水吸入综合征,或胎粪吸入综合征容易发生输液外渗。体重,气质类型的舒适性,气质类型的兴奋高峰,疾病,一般气质类型,新生儿的NBAS总分是输液外渗的独立危险因素。因此,不同的气质类型会对新生儿外渗产生影响。
    Infusion extravasation has an increased incidence in newborns, which can result in various adverse outcomes. This study aimed to investigate the effects of different types of temperament on infusion extravasation in newborns. A total of 209 newborns aged 4-7 days who were treated with infusion therapy were assessed for temperament type using the neonatal behavioral assessment scale score (NBAS). The 2009 Infusion Nurses Society clinical grading criteria for extravasation were used, and the clinical data of the newborns, such as gestational age and body weight, were collected. Out of 209 newborns assessed, 107 developed infusion extravasations, with an incidence rate of 51.2%. Newborns with intermediate temperament type were more prone to develop infusion extravasation. Newborns with low body weight, amniotic fluid aspiration syndrome, or meconium aspiration syndrome were prone to develop infusion extravasation. Body weight, temperament type of consolability, temperament type of peak of excitement, diseases, general temperament type, and NBAS total scores of the neonates were independent risk factors for infusion extravasation. Thus, different types of temperament can have an impact on neonatal extravasation.

    刚出生的女性,荷斯坦体重约38.5公斤的小牛发展严重,由位于小牛皱胃内的大初乳凝乳引起的持续性绞痛。基于10%的体重,出生后约30分钟,小牛被喂食4升(L)的初乳,第一次喂食后6小时再喂食2升的初乳。第一次和第二次喂食都使用食道管喂食器输送初乳。第二次初乳喂养后不久出现绞痛。受影响的小牛对农场支持性药物治疗无反应,并在绞痛发作后约22小时被穿透性的圈养螺栓人道安乐死。在当前的乳制品行业中通常观察到这种农场初乳喂养方案。这种情况表明,在相对较短的时间窗口内喂食大量初乳的小牛可能会发展成一个大的,皱胃内结实的初乳凝乳,引起腹胀,绞痛,偶尔死亡。迫切需要前瞻性分析研究,以确定最佳免疫球蛋白质量(g/L)和在最有利的时间范围内对第一次和第二次初乳饲喂新生小牛的初乳的理想体积。应制定指南,尽量减少对小腿健康和福祉产生不利影响的并发症,同时确保被动免疫的成功转移。
    A newborn female, Holstein calf weighing approximately 38.5 kg developed severe, persistent colic caused by a large colostrum curd located within the calf\'s abomasum. Based upon 10% body weight, the calf had been fed 4 liters (L) of first-milking colostrum approximately 30 min after birth and an additional 2 L of first-milking colostrum 6 h after the first feeding. Both the first and second feedings used an esophageal tube feeder to deliver the colostrum. Colic developed shortly after the second colostrum feeding. The affected calf did not respond to on-farm supportive medical therapy and was humanely euthanized by a penetrating captive bolt approximately 22 h after the onset of colic. This on-farm colostrum feeding protocol is routinely observed in the current dairy industry. This case demonstrates calves that are fed large volumes of colostrum during a relatively short window of time may develop a large, firm colostrum curd within the abomasum that causes abdominal distension, colic, and occasional death. There is an urgent need for prospective analytical studies that determine the optimal immunoglobulin mass (g/L) and the ideal volume of colostrum fed to newborn calves for both the first and second colostrum feedings within the most beneficial time frame. Guidelines should be developed that minimize complications that adversely affect calf health and well-being while ensuring the successful transfer of passive immunity.

    OBJECTIVE: Split abdominal wall muscle flap (SAWMF) is a technique to repair large defects in congenital diaphragmatic hernia (CDH). A possible objection to this intervention could be any associated abdominal muscle weakness. Our aim is to analyze the evolution of this abdominal muscle wall weakness.
    METHODS: Retrospective review of CDH repair by SAWMF (internal oblique muscle and transverse) from 2004 to 2023 focusing on the evolution of muscle wall weakness.
    RESULTS: Eighteen neonates of 148 CDH patients (12,1%) were repaired using SAWMF. Mean gestational age and birth weight were 35.7 ± 3.5 weeks and 2587 ± 816 g. Mean lung-to-head ratio was 1.49 ± 0.28 and 78% liver-up. Seven patients (38%) were prenatally treated by tracheal occlusion. Ninety-four percent of the flaps were used for primary repair and one to repair a recurrence. One patient (5.6%) experienced recurrence. Abdominal muscle wall weakness was present in the form of a bulge. Resolution of weakness at 1, 2 and 3 years was 67%, 89% and 94%, respectively. No patient required treatment for weakness or died.
    CONCLUSIONS: Abdominal muscular weakness after a split abdominal wall muscle flap repair is not a limitation for its realization since it is asymptomatic and presents a prompt spontaneous resolution.
    METHODS: IV.

    严重的新生儿低钠血症代表了严重的电解质失衡,具有潜在的严重的神经系统结局,一种在社区中很少记录的疾病,足月新生儿。这份报告强调了一个23天大的独特案例,以前很健康,足月男性新生儿出现严重低钠血症,导致癫痫发作,强调迅速承认和干预的紧迫性。新生儿出现呕吐等症状,呻吟,发冷,固定的凝视,和四肢震颤。入院时的关键发现包括体温过低,低血压,心动过速,并伴有明显的体重减轻。临床表现以脱水为标志,嗜睡,虚弱的哭泣,一个固定的目光,不规则呼吸,和粗糙的肺音,然而腹部扩张,高渗肢体运动,并观察到反复发作。立即干预包括建立IV准入,复温,机械通气,癫痫发作管理,体积膨胀,多巴胺用于循环支持,并开始使用经验性抗生素。诊断评估显示钠离子浓度为105.9mmol/L,而振幅整合脑电图(aEEG)检测到明显的癫痫发作活动,其特征是缺乏睡眠-觉醒节律,在较低和较高的振幅边缘明显升高,以及下降到5μV以下的下限电压的持续下降,呈现尖锐或锯齿状波形。管理策略需要使用高渗盐水和碳酸氢钠快速电解质正常化,抗惊厥治疗,和全面的支持性护理,持续的aEEG监测,直到癫痫发作停止。值得注意的是,第三天,新生儿的病情已经稳定,入院后10天健康出院。在16个月的随访中,患儿未出现神经系统不良结局,且生长发育良好.我们对病因进行了广泛的审查,临床表现,aEEG监测,重度新生儿低钠血症诱发癫痫的特点,治疗方法,严重低钠血症引发的癫痫发作的预后旨在加深对这种复杂疾病的认识并加强临床处理。它强调了早期检测的重要性,准确诊断,和定制治疗方案,以改善受影响新生儿的预后。此外,这篇综述强调了aEEG监测在管理癫痫发作风险升高的新生儿中不可或缺的作用.然而,快速使用高渗盐水纠正重度低钠血症诱发的癫痫发作的安全性和有效性,需要通过医学研究进行进一步研究.
    Severe neonatal hyponatremia represents a critical electrolyte imbalance with potentially severe neurological outcomes, a condition rarely documented in community-acquired, full-term newborns. This report underscores a unique case of a 23-day-old, previously healthy, full-term male neonate experiencing severe hyponatremia that precipitated seizures, underscoring the urgency of prompt recognition and intervention. The neonate presented with symptoms including vomiting, groaning, chills, fixed staring, and limb tremors. Critical findings upon admission encompassed hypothermia, hypotension, tachycardia, and tachypnea accompanied by significant weight loss. The clinical presentation was marked by dehydration, lethargy, weak crying, a fixed gaze, irregular breathing, and coarse lung sounds, yet a distended abdomen, hypertonic limb movements, and recurrent seizures were observed. Immediate interventions included establishing IV access, rewarming, mechanical ventilation, seizure management, volume expansion, dopamine for circulatory support, and initiation of empirical antibiotics. Diagnostic evaluations revealed a sodium ion concentration of 105.9 mmol/L, while amplitude-integrated electroencephalography (aEEG) detected pronounced seizure activity characterized by a lack of sleep-wake rhythmicity, noticeable elevation in both the lower and upper amplitude margins, and a sustained decrease in the lower margin voltage dropping below 5 μV, presenting as sharp or serrated waveforms. The management strategy entailed rapid electrolyte normalization using hypertonic saline and sodium bicarbonate, anticonvulsant therapy, and comprehensive supportive care, with continuous aEEG monitoring until the cessation of seizures. Remarkably, by the third day, the neonate\'s condition had stabilized, allowing for discharge in good health 10 days post-admission. At a 16-month follow-up, the child exhibited no adverse neurological outcomes and demonstrated favorable growth and development. Our extensive review on the etiology, clinical manifestations, aEEG monitoring, characteristics of seizures induced by severe neonatal hyponatremia, treatment approaches, and the prognosis for seizures triggered by severe hyponatremia aims to deepen the understanding and enhance clinical management of this complex condition. It stresses the importance of early detection, accurate diagnosis, and customized treatment protocols to improve outcomes for affected neonates. Additionally, this review accentuates the indispensable role of aEEG monitoring in managing neonates at elevated risk for seizures. Yet, the safety and efficacy of swiftly administering hypertonic saline for correcting severe hyponatremia-induced seizures necessitate further investigation through medical research.

    目的:探讨超高频腹部超声(UHFUS)扫描早产儿和足月儿的临床可行性。
    方法:前瞻性,19例健康足月新生儿接受了常规超声(CUS)检查(东芝,Aplioi700,线性探头14L5)和UHFUS(VisualsonicsVevoMD,线性探头UHF48和UHF70)根据标准化方案。进行壁厚测量;胃,小肠,结肠和腹膜.5名早产儿,有或没有可疑的坏死性小肠结肠炎(NEC),也用UHF48检查。其中,只有一个人后来被诊断为NEC。
    结果:在厚度测量中发现了CUS和UHFUS(UHF48)之间的差异;对于腹膜0.25与0.13mm(p<0.001),健康足月婴儿的小肠0.76对0.64mm(p=0.039)和结肠0.7对0.47mm(p<0.001)。从46到71MHz的频率增益显示腹膜测量值从0.13到0.09mm的平均减少(p<0.001)。一名患有NEC的早产儿的腹膜和胃肠壁厚度分别增加了五倍和两倍。与健康的早产儿相比。
    结论:UHFUS在临床上是可行的,有希望的方法,有可能改善婴儿的胃肠道诊断。与CUS相比,UHFUS的腹膜厚度和胃肠壁厚度较低,暗示CUS高估了。
    OBJECTIVE: To investigate the clinical feasibility of ultra-high-frequency abdominal ultrasound (UHFUS) scans of preterm and term infants.
    METHODS: Prospectively, 19 healthy term newborn infants were examined with conventional ultrasound (CUS) (Toshiba, Aplio i700, linear probe 14L5) and UHFUS (Visualsonics VevoMD, linear probes UHF48 and UHF70) according to a standardised protocol. Measurements of wall thickness were performed for; stomach, small intestine, colon and peritoneum. Five preterm infants, with or without suspected necrotising enterocolitis (NEC), were also examined with UHF48. Of these, only one was later diagnosed with NEC.
    RESULTS: Differences between CUS and UHFUS (UHF48) were found in measurements of thickness; for peritoneum 0.25 versus 0.13 mm (p < 0.001), small intestine 0.76 versus 0.64 mm (p = 0.039) and colon 0.7 versus 0.47 mm (p < 0.001) in healthy term infants. Gaining frequency from 46 to 71 MHz showed a mean reduction in measurements of peritoneum from 0.13 to 0.09 mm (p < 0.001). One preterm infant with NEC showed a fivefold and twofold increase in peritoneal and gastrointestinal wall thickness respectively, compared to healthy preterm infants.
    CONCLUSIONS: UHFUS was a clinically feasible, promising method with potential to improve gastrointestinal diagnostics in infants. Lower peritoneum thickness and gastrointestinal wall thickness were demonstrated with UHFUS compared to CUS, suggesting an overestimation by CUS.

    肝母细胞瘤(HB)是一种罕见的肝脏肿瘤,其先天性对应物(CHB)甚至更不频繁。CHB具有临床上具有挑战性的管理和普遍感知的较差结果。本研究旨在回顾CHB的文献,以更好地定义演示文稿,诊断,可用的治疗和管理选择。结果分析表明,很大一部分死亡率与肿瘤的恶性性质无关。确定了影响总体结局的关键因素:在产前(22%)和围产期(32%)阶段与“质量效应”相关的死亡率。以及肿瘤死亡率,包括肿瘤和/或治疗相关因素(46%)。总的来说,出生后,CHB本身似乎并不意味着更糟糕的肿瘤预后,应该像年龄较大的孩子一样管理,如果患者足够稳定,可以进行适当的分期和治疗。更深入的知识和更好的结果将来自于一个大的,同质,可能允许全球协议的数据收集,专注于CHB的全面管理。
    Hepatoblastoma (HB) is a rare liver tumour, and its congenital counterpart (CHB) is even less frequent. CHB has a clinically challenging management and a generally perceived worse outcome. This study aims to review the literature on CHB to better define presentation, diagnosis, available treatments and management options. The analysis of outcomes suggests that a significant portion of mortality is unrelated to the malignant nature of the tumour. Key factors influencing overall outcomes were identified: mortality linked to the \'mass effect\' during both the prenatal (22%) and perinatal (32%) stages, as well as \'oncological\' mortality encompassing tumour and/or treatment-related factors (46%). Overall, after birth, CHB does not seem to confer a worse oncological prognosis per se, and should be managed similarly to older children, if patients are stable enough to undergo proper staging and treatment. A deeper knowledge and better outcomes would come from a large, homogeneous, collection of data possibly allowing a global protocol, focusing on a comprehensive management of CHB.
