Assessing Stable Characteristics of Endocrine Function Among Boys and Girls with Prenatal Alcohol Exposure as a Novel Clinical Tool

受产前酒精暴露(PAE)影响的个体可能会出现复杂的认知、 行为、身体和精神健康问题，称为胎儿酒精谱系障碍(FASD)。的 尤其重要的是，高达90%的FASD患者可能会在一生中经历心理健康问题 当然了。PAE的动物模型表明，神经内分泌功能的改变是 心理健康问题增加的神经生物学机制；因此，改善或正常化内分泌 功能可能为改善结果提供一种新的方法。K01建议的主要目的是 加快应聘者的学习机会，通过以下方式解决知识的翻译差距 检测PAE患者内分泌活动的个体差异及其对 对心理健康问题的易感性。为此，候选人的独特和独立的目标 利用NIH资助的2个独立研究项目：1)550名青少年(33%的PAE；33%的非PAE 酗酒的母亲；33%不喝酒的母亲；50%的女孩；9-12岁)来自青少年的大脑 美国的认知发展(ABCD)研究，以及2)160名青少年(所有青少年中50%的PAE 怀孕三个月；50%无PAE；50%女孩；9-12岁)，作为产前酒精小岛屿发展中国家和死产的一部分 (通过)南非的出生队列。K01建议：a)利用资助的神经成像和产前检查 ABCD/PASS中的物质暴露数据；B)利用资助的ABCD关于荷尔蒙、青春期和精神的数据 C)收集有关荷尔蒙、青春期和心理健康的新通行证数据。评估大脑的方法， 心理健康和青春期将在ABCD和PASS队列之间协调，但将有明显的 不同的实验设计，每一种都有其独特的优点和局限性。这些对比鲜明的队列 设计和人口为加快学习机会提供了难得的机会 提高我们识别最重要的方差成分以了解个体的能力 青少年PAE患者内分泌功能的差异。组别将在年龄、性别、种族和社会地位方面进行匹配 在他们各自的队列中。ABCD队列的初步发现将为独立通过的测试提供信息 样本，为解释不同社会、种族和文化的研究结果的概括性提供了力量 环境。候选人的培训将利用多样化指导团队的丰富专业知识 为了整合内分泌功能的中枢/外周测量，通过连接神经成像领域， 神经内分泌学、唾液生物科学和生物统计学，以更好地了解 内分泌功能。该培训计划利用了CHLA的中心位置，并包括教学课程 以及USC(潜在状态特征建模课程)、UCI(唾液生物科学课程)的一对一指导 加州大学洛杉矶分校(UCLA，MPlus)该培训计划将通过学习如何整合两种技术来培养新的神经成像专业知识 成像模式，以及建立唾液生物科学、生物统计学和心理健康方面的专门知识。

Individuals affected by prenatal alcohol exposure (PAE) can present with a complex profile of cognitive, behavioral, physical, and mental health problems, referred to as fetal alcohol spectrum disorder (FASD). Of particular relevance, up to 90% of individuals with FASD may experience mental health problems over the life course. Animal models of PAE demonstrate that alterations in neuroendocrine function serve as a fundamental neurobiological mechanism for increased mental health problems; thus, improving or normalizing endocrine function may provide a novel approach for improving outcomes. The primary aim of the K01 proposal is to accelerate the candidate's learning opportunities to addresses this translational gap in knowledge through examination of individual differences in endocrine activity in humans with PAE, and their implications for susceptibility for mental health problems. Towards this end, the candidate's unique and independent aims capitalize on 2 independent NIH-funded research programs: 1) 550 adolescents (33% PAE; 33% non-PAE with drinking moms; 33% non-PAE with non-drinking moms; 50% girls; aged 9-12 years) from the Adolescent Brain Cognitive Development (ABCD) study in the United States, and 2) 160 adolescents (50% PAE across all trimesters; 50% non-PAE; 50% girls; aged 9-12 years) as part of the Prenatal Alcohol SIDS and Stillbirth (PASS) birth cohort in South Africa. The K01 proposes to: A) utilize funded neuroimaging and prenatal substance exposure data in ABCD/PASS; B) utilize funded ABCD data on hormones, puberty and mental health; and C) collect new PASS data on hormones, puberty and mental health. Methods for assessing brain, mental health, and puberty will be harmonized between ABCD and PASS cohorts, yet there will be distinctly different experimental designs, each with their unique strengths and limitations. These contrasting cohort designs and populations provide a rare opportunity for acceleration of learning opportunities as well as advancement of our ability to identify the most important components of variance for understanding individual differences in endocrine function in adolescents with PAE. Groups will be matched on age, sex, race and SES within their respective cohorts. Initial findings from the ABCD cohort will inform tests in the independent PASS sample, providing strength for interpreting generalizability of findings across diverse social, racial and cultural environments. The candidate's training will take advantage of the rich expertise of the diverse mentoring team to integrate central/peripheral measures of endocrine function, by bridging the fields of neuroimaging, neuroendocrinology, salivary biosciences and biostatistics to better understand individual differences in endocrine function. The training plan capitalizes on the central location of CHLA, and includes didactic courses and one-on-one mentoring at USC (latent state trait modeling course), UCI (salivary bioscience course), and UCLA (MPlus). The training plan will foster new neuroimaging expertise through learning how to integrate two imaging modalities, as well as building expertise in salivary biosciences, biostatistics and mental health.
