    对儿科死亡率的日益关注要求在临床环境中加强准备,特别是在重症监护病房(ICU)内。由于与呼吸相关的入院占儿科疾病的很大一部分,在这些病例中,迫切需要预测ICU死亡率.这项研究基于1188名患者的数据,使用机器学习技术和研究不同类别平衡方法来预测儿科ICU死亡率,解决了这一必要性。本研究采用可公开访问的“儿科重症监护数据库”进行培训,验证,并测试用于预测儿科患者死亡率的机器学习模型。使用三种机器学习特征选择技术对特征进行排名,即随机森林,额外的树木,和XGBoost,导致从总共105个特征中选择16个关键特征。使用十种机器学习模型和集成技术来进行准确的死亡率预测。为了解决数据集中固有的类不平衡,我们应用了一种独特的数据分区技术来增强模型与数据分布的一致性。CatBoost机器学习模型的曲线下面积(AUC)为72.22%,而叠加集合模型对死亡率预测的AUC为60.59%。拟议的细分技术,另一方面,提供了性能指标的显著改进,AUC为85.2%,准确率为89.32%。这些发现强调了机器学习在提高儿科死亡率预测和告知改善ICU准备的策略方面的潜力。
    The growing concern of pediatric mortality demands heightened preparedness in clinical settings, especially within intensive care units (ICUs). As respiratory-related admissions account for a substantial portion of pediatric illnesses, there is a pressing need to predict ICU mortality in these cases. This study based on data from 1188 patients, addresses this imperative using machine learning techniques and investigating different class balancing methods for pediatric ICU mortality prediction. This study employs the publicly accessible \"Paediatric Intensive Care database\" to train, validate, and test a machine learning model for predicting pediatric patient mortality. Features were ranked using three machine learning feature selection techniques, namely Random Forest, Extra Trees, and XGBoost, resulting in the selection of 16 critical features from a total of 105 features. Ten machine learning models and ensemble techniques are used to make accurate mortality predictions. To tackle the inherent class imbalance in the dataset, we applied a unique data partitioning technique to enhance the model\'s alignment with the data distribution. The CatBoost machine learning model achieved an area under the curve (AUC) of 72.22%, while the stacking ensemble model yielded an AUC of 60.59% for mortality prediction. The proposed subdivision technique, on the other hand, provides a significant improvement in performance metrics, with an AUC of 85.2% and an accuracy of 89.32%. These findings emphasize the potential of machine learning in enhancing pediatric mortality prediction and inform strategies for improved ICU readiness.

    粘多糖是罕见的溶酶体贮积症,糖胺聚糖在组织中积累,导致多器官功能障碍.I型粘多糖贮积病是由缺乏α-L-艾杜糖醛酸酶引起的常染色体隐性遗传病,导致皮肤素和硫酸乙酰肝素的积累。早期诊断对于早期治疗和改善预后至关重要。我们报告了一例具有经典临床特征的女性儿童,该儿童被早期诊断,可以进行造血干细胞移植并减缓疾病进展。她出生时出现白线和脐疝和腹股沟疝。从生命的头几个月开始,她反复呼吸道感染。九个月时,注意到电机延迟,在20个月时,颅骨融合症通过手术矫正。粗糙的面部特征,胸腰椎后凸畸形,肝肿大促使尿糖胺聚糖研究在22个月时进行,显示水平升高。干血斑检测中的Alfa-L-艾杜糖苷酶活性较低,与粘多糖贮积症I型相容的基因IDUA的分子检测,进行遗传咨询,揭示了致病变异c.120G>A(p。Trp402Ter)和c.1598C>G(p。Pro533Arg)中的复合杂合度。26个月时,她的发育商是她这个年龄的平均水平。她在29个月时开始酶替代疗法,并在33个月时接受造血干细胞移植,软化了粗糙的特征,减少呼吸道感染,和改善肝肿大。然而,五岁时,她的发育商数为76(平均值=100,标准偏差=15)。通过早期的诊断和治疗,这种智力障碍可能已经得到预防。
    Mucopolysaccharidoses are rare lysosomal storage disorders in which glycosaminoglycans accumulate in tissues, causing multiorgan dysfunction. Mucopolysaccharidosis type I is an autosomal recessive disease caused by a deficiency of the enzyme alpha-L-iduronidase, resulting in the accumulation of dermatan and heparan sulfate. Early diagnosis is crucial for early treatment and improved outcomes. We report the case of a female child with classic clinical features who was diagnosed early which allowed hematopoietic stem cell transplantation and slowed disease progression. She presented at birth with linea alba and umbilical and inguinal hernias. Since the first months of life, she had recurrent respiratory infections. At nine months, a motor delay was noticed, and at 20 months, craniosynostosis was corrected with surgery. Coarse facial features, thoracolumbar kyphosis, and hepatomegaly prompted a urinary glycosaminoglycan study at 22 months, which showed elevated levels. Alfa-L-iduronidase activity in dried blood spot testing was low, compatible with mucopolysaccharidosis type I. Molecular testing of gene IDUA, performed for genetic counseling, revealed the pathogenic variants c.1205G>A (p.Trp402Ter) and c.1598C>G (p.Pro533Arg) in compound heterozygosity. At 26 months, her development quotient was average for her age. She started enzyme replacement therapy at 29 months and underwent hematopoietic stem cell transplantation at 33 months, which softened the coarse features, reduced respiratory infections, and improved hepatomegaly. However, at age five, her development quotient was 76 (mean = 100, standard deviation = 15). This intellectual impairment might have been prevented with an earlier diagnosis and treatment.

    BACKGROUND: Sepsis is associated with about 20% of deaths worldwide. It often presents with non-specific initial symptoms, making its emergency treatment an interdisciplinary and cross-sectoral challenge. Three in four sepsis survivors suffers from new cognitive, psychological, or physical sequelae for which specific treatment concepts are scarce. The AVENIR project aims to improve the understanding of patient pathways, and subjective care experiences and needs along the entire healthcare pathway before, with and after sepsis. Based on this, concrete recommendations for the organization of care and patient information materials will be developed with close patient participation.
    METHODS: Mixed-methods study including (1) analysis of anonymized nationwide health claims data from Germany, (2) linkage of health claims data with patient care reports (PCR) of emergency medical services from study regions in two federal states within Germany, and (3) qualitative exploration of the patient, relative, and care provider perspective on sepsis care. In (1), we analyze inpatient and outpatient health care utilization until 30 days pre-sepsis; clinical sepsis care including intra- and inter-hospital transfers; and rehabilitation, inpatient and outpatient aftercare of sepsis survivors as well as costs for health care utilization until 24 months post-sepsis. We attempt to identify survivor classes with similar health care utilization by Latent Class Analyses. In (2), PCR are linked with health claims data to establish a comprehensive database outlining care pathways for sepsis patients from pre-hospital to follow-up. We investigate e.g., whether correct initial assessment is associated with acute (e.g., same-day lethality) and long-term (e.g., new need for care, long-term mortality) outcomes of patients. We compare the performance of sepsis-specific screening tools such as qSOFA, NEWS-2 or PRESEP in the pre-clinical setting. In (3), semi-structured interviews as well as synchronous and asynchronous online focus groups are conducted and analyzed using qualitative content analyses techniques.
    CONCLUSIONS: The results of the AVENIR study will contribute to a deeper understanding of sepsis care pathways in Germany. They may serve as a base for improvements and innovations in sepsis care, that in the long-term can contribute to reduce the personal, medical, and societal burden of sepsis and its sepsis sequelae.
    BACKGROUND: Registered at German Clinical Trial Register (ID: DRKS00031302, date of registration: 5th May 2023).

    非动脉炎性缺血性视神经病变(NAION)很少发生在突然血管受损的情况下,尤其是在有“磁盘风险”外观的患者中。贫血和低血压被认为是休克诱导的NAION的主要诱因。对这种现象的早期识别可以防止进一步的视力丧失并导致部分视力恢复。我们在这里介绍了一名56岁的患者,该患者发展为NAION,其特征是在感染性休克的情况下因低血压而导致双眼视盘水肿和左眼视力丧失。他接受了积极的血压管理(停止了所有的抗高血压药,水合作用,和midrodrine),可稳定右眼的视力,并可能防止左眼的进一步视力丧失。
    Non-arteritic ischemic optic neuropathy (NAION) can rarely occur in the setting of sudden vascular compromise, especially in patients with a \"disk-at-risk\" appearance. Anemia and hypotension are believed to be the main precipitators of shock-induced NAION. Early recognition of this phenomenon can prevent further visual loss and result in partial visual recovery. We here present a 56-year-old patient who developed NAION characterized by optic disc edema in both eyes and visual loss in the left eye secondary to hypotension in the setting of septic shock. He received aggressive blood pressure management (stopping all his anti-hypertensives, hydration, and midrodrine) which resulted in stabilization of vision in the right eye and likely prevented further visual loss in the left eye.

    腺病毒肺炎常见于小儿上呼吸道感染,相对容易发展为重症病例,死亡率高,后遗症多。至于发病机制,腺病毒可以直接损伤靶细胞,并在不同程度上激活免疫反应。早期临床识别取决于患者的症状和实验室检查,包括2岁以下的人,伴有全身毒性症状的呼吸困难,CT图像中的肺不张或肺气肿,白细胞减少,C反应蛋白(CRP)和降钙素原(PCT)显著升高,表明严重病例的可能性。直到现在,目前尚无针对腺病毒肺炎的特效药,所以在临床实践中,目前的治疗包括抗病毒药物,呼吸支持和支气管镜检查,免疫调节治疗,血液净化。此外,感染后闭塞性细支气管炎(PIBO),噬血细胞综合征,死亡应该小心。与PIBO发展相关的独立危险因素是有创机械通气,静脉注射类固醇,发烧的持续时间,和男性性别。同时,低氧血症,高碳酸血症,有创机械通气,低血清白蛋白水平与死亡有关。其中,病毒载量和血清学鉴定不仅是腺病毒肺炎的“金标准”,但也与严重程度和预后有关。这里,我们讨论了发病机制的进展,早期识别,治疗,以及重症小儿腺病毒肺炎不良结局的危险因素。
    Adenovirus pneumonia is common in pediatric upper respiratory tract infection, which is comparatively easy to develop into severe cases and has a high mortality rate with many influential sequelae. As for pathogenesis, adenoviruses can directly damage target cells and activate the immune response to varying degrees. Early clinical recognition depends on patients\' symptoms and laboratory tests, including those under 2 years old, dyspnea with systemic toxic symptoms, atelectasis or emphysema in CT image, decreased leukocytes, and significantly increased C-reaction protein (CRP) and procalcitonin (PCT), indicating the possibility of severe cases. Until now, there is no specific drug for adenovirus pneumonia, so in clinical practice, current treatment comprises antiviral drugs, respiratory support and bronchoscopy, immunomodulatory therapy, and blood purification. Additionally, post-infectious bronchiolitis obliterans (PIBO), hemophagocytic syndrome, and death should be carefully noted. Independent risk factors associated with the development of PIBO are invasive mechanical ventilation, intravenous steroid use, duration of fever, and male gender. Meanwhile, hypoxemia, hypercapnia, invasive mechanical ventilation, and low serum albumin levels are related to death. Among these, viral load and serological identification are not only \"gold standard\" for adenovirus pneumonia, but are also related to the severity and prognosis. Here, we discuss the progress of pathogenesis, early recognition, therapy, and risk factors for poor outcomes regarding severe pediatric adenovirus pneumonia.

    一名儿童性虐待的幸存者认为,医生错过了注意到她痛苦的机会,十四岁,她患有一种无法解释的疾病,持续了一年。原因,她写道,被医生解释为心理上的,但没有人进一步质疑。为什么???...如果成年人不听[,]那我们就没有人可以求助了。“几十年来,社区卫生从业人员被认为是保护儿童免受虐待的重要群体,但是幸存者的证词和机构的统计数据表明,他们很少收到口头披露或认识到性虐待的身体或行为警告迹象。我们对1980年代的描述表明,迅速提高了专业意识,随后是十年后期的强烈反对,这阻碍了从业者对他们的担忧采取行动。本文使用贸易和专业期刊,培训材料,教科书,和新的口述历史,以考虑为什么社区的医生和护士一直在努力注意和回应性虐待的孩子。它将争辩说,社区卫生从业人员在工作场所遇到的儿童性虐待的概念模型鼓励对虐待的怀疑采取机械和程序上的反应。在一个高度性别化和有争议的工作场所,从业者对幸存者的感受,不虐待的家庭成员,应该理解,肇事者在培训或实践中很少被辩论。从事性虐待的从业者的情感成本,以及他们对自反性空间和支撑结构的需求,被忽略。
    A survivor of child sexual abuse felt that doctors missed opportunities to notice her distress when, at fourteen, she had an unexplained illness that lasted for a year. The cause, she wrote, was \"explained by Doctors as psychological, but nobody questioned further. WHY??? … If adults don\'t listen[,] then we have no one to turn to.\" For decades, community health practitioners have been identified as an important group in protecting children from maltreatment, but survivor testimony and agency statistics demonstrate that they rarely receive verbal disclosures or recognize the physical or behavioural warning signs of sexual abuse. The accounts we have of the 1980s tell of swiftly heightening professional awareness, followed by a visceral backlash in the latter part of the decade that discouraged practitioners from acting on their concerns. This article uses trade and professional journals, training materials, textbooks, and new oral histories to consider why community-based doctors and nurses have struggled to notice and respond to the sexually abused child. It will argue that the conceptual model of child sexual abuse that community health practitioners encountered in the workplace encouraged a mechanical and procedural response to suspicions of abuse. In a highly gendered and contested workplace, practitioners\' feelings about how survivors, non-abusing family members, and perpetrators should be understood were rarely debated in training or in practice. The emotional cost to the practitioners of engagement with sexual abuse, and their need for spaces of reflexivity and structures of support, were ignored.

    UNASSIGNED: To assess accuracy of early diagnosis, appropriateness and timeliness of response, and clinical outcomes of older general medical inpatients with hospital-acquired sepsis.
    UNASSIGNED: Hospital abstracts of inpatient encounters from seven digital Queensland public hospitals between July 2018 and September 2020 were screened retrospectively for diagnoses of hospital-acquired sepsis. Electronic medical records were retrieved and cases meeting selection criteria and classified as confirmed or probable sepsis using pre-specified criteria were included. Investigations and treatments following the first digitally generated alert of clinical deterioration were compared with a best practice sepsis care bundle. Outcome measures comprised 30-day all-cause mortality after deterioration, and unplanned readmissions at 14 days after discharge.
    UNASSIGNED: Of the 169 screened care episodes, 59 comprised probable or confirmed cases of sepsis treated by general medicine teams at the time of initial deterioration. Of these, 43 (72.9%) had no mention of sepsis in the differential diagnosis on first medical review, and only 38 (64%) were managed as having sepsis. Each care bundle component of blood cultures, serum lactate, and intravenous fluid resuscitation and antibiotics was only delivered in approximately 30% of cases, and antibiotic administration was delayed more than an hour in 28 of 38 (73.7%) cases.
    UNASSIGNED: Early recognition of sepsis and timely implementation of care bundles are challenging in older general medical patients. Education programs in sepsis care standards targeting nurses and junior medical staff, closer patient monitoring, and post-discharge follow-up may improve patient outcomes.

    数字技术有可能支持精神病诊断,特别是,在不久的将来,自闭症谱系障碍的鉴别诊断,使临床决策更加客观,可靠和循证,同时减少临床资源。认知时症状的多模态自动化测量,行为,和神经元水平与人工智能应用相结合,为个性化预测和治疗策略提供了有希望的进步。此外,这些新技术可以实现对纵向症状发展的系统和连续评估,超出了通常的临床实践范围。早期认识到恶化并简化,以及详细的,进展控制将成为可能。最终,数字辅助诊断将促进早期识别。尽管如此,数字技术不能也不应该取代考虑自闭症谱系障碍个体纵向和横截面表现的综合复杂性的临床决策。然而,它们可以通过客观化决策过程来帮助临床医生,并为临床环境中的资源提供可喜的救济。
    Digital technologies have the potential to support psychiatric diagnostics and, in particular, differential diagnostics of autism spectrum disorder in the near future, making clinical decisions more objective, reliable and evidence-based while reducing clinical resources. Multimodal automatized measurement of symptoms at cognitive, behavioral, and neuronal levels combined with artificial intelligence applications offer promising strides toward personalized prognostics and treatment strategies. In addition, these new technologies could enable systematic and continuous assessment of longitudinal symptom development, beyond the usual scope of clinical practice. Early recognition of exacerbation and simplified, as well as detailed, progression control would become possible. Ultimately, digitally assisted diagnostics will advance early recognition. Nonetheless, digital technologies cannot and should not substitute clinical decision making that takes the comprehensive complexity of individual longitudinal and cross-section presentation of autism spectrum disorder into account. Yet, they might aid the clinician by objectifying decision processes and provide a welcome relief to resources in the clinical setting.

    Perioperative critical events will affect the quality of medical services and threaten the safety of patients. Using scientific methods to evaluate the perioperative risk of critical illness is of great significance for improving the quality of medical services and ensuring the safety of patients.
    At present, the traditional scoring system is mainly used to predict the score of critical illness, which is mainly dependent on the judgment of doctors. The result is affected by doctors\' knowledge and experience, and the accuracy is difficult to guarantee and has a serious lag. Besides, the statistical prediction method based on pure data type do not make use of the patient\'s diagnostic text information and cannot identify comprehensive risk factor. Therefore, this paper combines the text features extracted by deep neural network with the pure numerical type features extracted by XGBOOST to propose a deep neural decision gradient boosting model. Supervised learning was used to train the risk prediction model to analyze the occurrence of critical illness during the perioperative period for early warning.
    We evaluated the proposed methods based on the real data of critical illness patients in one hospital from 2014 to 2018. The results showed that the critical disease risk prediction model based on multiple modes had faster convergence rate and better performance than the risk prediction model based on text data and pure data type.
    Based on the machine learning method and multi-modal data of patients, this paper built a prediction model for critical adverse events in patients, so that the risk of critical events can be predicted for any patient directly based on the preoperative and intraoperative characteristic data. At present, this work only classifies and predicts the occurrence of critical illness during or after operation based on the preoperative examination data of patients, but does not discuss the specific time when the patient was critical illness, which is also the direction of our future work.
