摘要:

该组织认识到,个人同时暴露于多种不同的环境因素,并采取全面的方法来发现疾病的病因。然而,在试图量化复杂暴露混合物对健康的影响时,出现了挑战。分析的挑战包括处理高维度,研究这些暴露及其相互作用的综合影响,整合因果途径,整合组学层。为了应对这些挑战,ISGlobal Exposome Hub举办了一场数据挑战活动,向来自世界各地和所有专业领域的研究人员开放。分析师有机会在一个常见的部分模拟的麻烦数据集上竞争和应用最先进的方法(基于HELIX项目的真实病例数据),在不同时间点,一般和个人环境产生多个相关暴露变量(P>100),生物分子数据(多组学:DNA甲基化,基因表达,蛋白质,代谢组学)和1301对母子的多种临床表型。大多数方法包括特征选择或特征约简,以处理复杂数据集的高维性。有几种方法使用线性指数模型或响应面方法(包括贝叶斯方法)明确搜索暴露和/或其相互作用的综合效应。其他方法使用多步骤方法在中介分析中处理多组学数据集。在这里,我们讨论了统计模型,并提供了使用的数据和代码,以便分析人员有实施的例子,并可以学习如何使用这些方法。总的来说,麻烦的数据挑战为来自不同学科的研究人员提供了一个独特的机会来创建和共享方法,为麻烦和环境健康领域的开放科学设定了新的标准。

英文摘要:

The exposome recognizes that individuals are exposed simultaneously to a multitude of different environmental factors and takes a holistic approach to the discovery of etiological factors for disease. However, challenges arise when trying to quantify the health effects of complex exposure mixtures. Analytical challenges include dealing with high dimensionality, studying the combined effects of these exposures and their interactions, integrating causal pathways, and integrating omics layers. To tackle these challenges, ISGlobal Exposome Hub held a data challenge event open to researchers from all over the world and from all expertises. Analysts had a chance to compete and apply state-of-the-art methods on a common partially simulated exposome dataset (based on real case data from the HELIX project) with multiple correlated exposure variables (P>100) arising from general and personal environments at different time points, biological molecular data (multi-omics: DNA methylation, gene expression, proteins, metabolomics) and multiple clinical phenotypes in 1301 mother-child pairs. Most of the methods presented included feature selection or feature reduction to deal with the high dimensionality of the exposome dataset. Several approaches explicitly searched for combined effects of exposures and/or their interactions using linear index models or response surface methods, including Bayesian methods. Other methods dealt with the multi-omics dataset in mediation analyses using multiple-step approaches. Here we discuss the statistical models and provide the data and codes used, so that analysts have examples of implementation and can learn how to use these methods. Overall, the exposome data challenge presented a unique opportunity for researchers from different disciplines to create and share methods, setting a new standard for open science in the exposome and environmental health field.
