The SARS-CoV-2 pandemic has manifested in children with a wide spectrum of clinical presentations ranging from asymptomatic infection to devastating acute respiratory symptoms, appendicitis (often with rupture), and Multisystem Inflammatory Syndrome in Children (MIS-C), a serious inflammatory condition presenting several weeks after exposure to or infection with the virus. These presentations overlap in their clinical severity while maintaining distinct clinical profiles. Public health and clinical approaches will benefit from an improved understanding of the spectrum of illness associated with SARS CoV-2 and from the capacity to integrate data to achieve two goals: (i) to identify the clinical, social, and biological variables that predict severe COVID-19 and MIS-C, and (ii) to target those populations and individuals at greatest risk for harm from the virus. We propose the COVID-19 Network of Networks Expanding Clinical and Translational approaches to Predict Severe Illness in Children (CONNECT to Predict SIck Children) comprising eight partners providing access to data on >15 million children. Our network will systematically integrate social, epidemiological, genetic, immunological, and computational approaches to identify both population- and individual-level risk factors for severe illness. Our underlying hypothesis is that a combination of multidimensional data – clinical, sociodemographic, epidemiologic, and biological -- can be integrated to predict which children are at greatest risk to have severe consequences from SARS-CoV-2 infection. To test our hypothesis, we will develop CONNECT to Predict SIck Children, a network of networks that leverages inpatient, outpatient, community, and epidemiological data resources to support the analysis of large data using machine learning and model-based analyses. For the R61 phase, we will develop and refine predictive models using data from our network of networks (Aim 1). We will also recruit participants previously diagnosed with either COVID-19 or MIS-C (along with appropriate controls who have had mild or asymptomatic infections with SARS-CoV2), who will provide survey data (including social determinants) and saliva and blood samples to identify persisting biological factors associated with severe disease (Aim 2). We will iteratively assess our models using a knowledge management framework that considers the marginal value of data for improving models' predictive capacity over time. In the R33 phase, we will validate and further refine predictive models incorporating data from additional participants recruited throughout our network of networks, including newly infected children with severe COVID-19 or MIS-C identified through real-time surveillance (Aim 3). We seek to develop predictive models for children and adolescents that are useful, sensitive to community and environmental contexts, and informed by the REASSURED framework specified by the RFA. The models and biomarkers developed through our nationwide network of networks will produce generalizable knowledge that will improve our ability to predict which children are at greatest risk for severe complications of SARS-CoV- 2 infection. This knowledge will facilitate interventions to prevent and treat severe pediatric illness.

SARS-CoV-2 大流行已在儿童中出现，其临床表现多种多样，包括： 从无症状感染到毁灭性的急性呼吸道症状、阑尾炎（通常伴有破裂）和 儿童多系统炎症综合征 (MIS-C)，一种严重的炎症性疾病，可导致多种症状 接触或感染病毒几周后，这些表现的临床严重程度有所重叠。 保持独特的临床特征将受益于改进的公共卫生和临床方法。 了解与 SARS CoV-2 相关的疾病谱以及整合数据的能力 实现两个目标：(i) 确定预测重症 COVID-19 的临床、社会和生物变量 MIS-C，以及 (ii) 针对受病毒伤害风险最大的人群和个人。 COVID-19 网络网络扩展预测严重疾病的临床和转化方法 儿童（CONNECT to Predict SIck Children）由八个合作伙伴组成，提供 >15 岁以上的数据访问 我们的网络将系统地整合社会、流行病学、遗传、免疫学和 确定人群和个人层面的严重疾病风险因素的计算方法。 基本假设是多维数据的组合——临床、社会人口学、流行病学、 和生物学——可以综合起来预测哪些儿童最有可能遭受严重后果 为了检验我们的假设，我们将开发 CONNECT 来预测生病的儿童，这是一个 利用住院患者、门诊患者、社区和流行病学数据资源来 支持使用机器学习和基于模型的分析来分析大数据。对于 R61 阶段，我们。 将使用我们网络中的数据开发和完善预测模型（目标 1）。 之前被诊断患有 COVID-19 或 MIS-C 的参与者（以及曾经患有过类似疾病的适当对照） SARS-CoV2 轻度或无症状感染者），谁将提供调查数据（包括社会决定因素） 唾液和血液样本，以确定与严重疾病相关的持续生物因素（目标 2）。 将使用考虑边际价值的知识管理框架迭代评估我们的模型 随着时间的推移，我们将验证并进一步完善模型的预测能力。 预测模型结合了我们在整个网络中招募的其他参与者的数据， 包括通过实时监测发现的患有严重 COVID-19 或 MIS-C 的新感染儿童（Aim 3) 我们寻求为儿童和青少年开发有用且对社区敏感的预测模型。 和环境背景，并由 RFA 指定的 REASSURED 框架提供信息。 通过我们全国网络开发的生物标志物将产生普遍的知识 这将提高我们预测哪些儿童最有可能罹患 SARS-CoV 严重并发症的能力 2 感染。这些知识将有助于预防和治疗严重儿科疾病的干预措施。
