项目摘要

DESCRIPTION (provided by applicant): This application for a K23 Mentored Patient-Oriented Research Career Development Award details a 5-year plan for training and research activities that will provide the skills and experience I need to achieve success as an independent investigator studying the roles of nutrition in fetal alcohol spectrum disorder (FASD). I am currently in my final academic year of a research fellowship in the Scholars in Clinical Science Program at Harvard Medical School and a clinical fellowship in Pediatric Emergency Medicine at Children's Hospital Boston, where I will begin a faculty position at the start of the proposed funding period. This K23 award will provide me with the support necessary to accomplish the following goals: (1) to assess the nutritional status of heavy drinking pregnant; (2) to examine the impact of maternal nutritional status on fetal alcohol-related growth restriction; (3) to gain expertise in nutritional physiology and alcohol-related teratology that will prepare me to conduct studies examining the roles of pre- and postnatal nutrition in FASD; and finally (4) to gain expertise in planning and executing pediatric patient-oriented research, and thereby develop an independent research career. To achieve these goals, I have assembled a mentoring team comprised of a primary mentor, Christopher Duggan, MD, Director of Clinical Research in the Division of Gastroenterology and Nutrition at Children's Hospital Boston, who conducts research in the fields of pediatric nutrition, gastroenterology, and global child health; and co-mentor Sandra Jacobson, PhD, Professor of Psychiatry and Behavioral Neurosciences at Wayne State University School of Medicine, who has expertise in examining the developmental effects of in utero exposure to neurotoxic agents, most notably alcohol and polychlorinated biphenyls (PCBs). Although it has been widely postulated that maternal nutritional status may interact with prenatal alcohol exposure in FASD, to our knowledge, there have been no published studies in humans examining the nutritional status of heavy drinking pregnant woman or the impact of their nutritional status on the teratogenesis of alcohol. The studies proposed here are designed to test the hypotheses that the nutritional status of heavy drinking pregnant women is poorer than that of women who abstain and that poor maternal nutritional status exacerbates alcohol-related prenatal growth restriction. I will use the resources available to me at Children's Hospital Boston, Harvard Medical School, the Harvard School of Public Health and the University of Cape Town to add these studies to a previously planned, NIH-funded prospective cohort study of heavy drinking pregnant women and abstainers/light-drinkers, focusing on 3 nutritional domains: 1) energy intake and gestational weight gain; 2) iron status; 3) methyl donor status (folate, vitamin B12, choline). These research activities in combination with structured coursework and didactics will give me the training, skills, and hands-on experience needed to develop into an independent investigator with an ongoing research program examining the potential roles of pre- and postnatal nutrition in FASD.

描述（由申请人提供）：K23指导的以患者为导向的研究职业发展奖的申请详细介绍了培训和研究活动的5年计划，这些活动将提供我作为一名独立研究者成功学习营养在胎儿酒精谱系障碍（FASD）中的作用所需的技能和经验。我目前在哈佛医学院临床科学项目学者研究奖学金和波士顿儿童医院儿科急诊医学临床奖学金的最后一个学年，在拟议的资助期开始时，我将开始教职。这个K23奖将为我提供必要的支持，以实现以下目标：（1）评估重度饮酒孕妇的营养状况;（2）检查母亲营养状况对胎儿酒精相关生长受限的影响;（3）获得营养生理学和酒精相关畸形学方面的专业知识，这将使我做好准备，进行研究，检查前和产后营养FASD;和最后（4）获得规划和执行儿科患者为导向的研究的专业知识，从而发展一个独立的研究生涯。为了实现这些目标，我组建了一个指导团队，由主要导师Christopher Duggan博士组成，他是波士顿儿童医院胃肠病学和营养部临床研究主任，负责儿科营养、胃肠病学和全球儿童健康领域的研究;和共同导师桑德拉·雅各布森博士，韦恩州立大学医学院精神病学和行为神经科学教授，他在检查子宫内暴露于神经毒性剂，特别是酒精和多氯联苯（PCB）对发育的影响方面具有专业知识。尽管人们普遍认为母亲的营养状况可能与FASD的产前酒精暴露相互作用，但据我们所知，目前还没有发表的研究，研究了大量饮酒孕妇的营养状况或其营养状况对酒精致畸作用的影响。这里提出的研究旨在验证这样的假设：大量饮酒的孕妇的营养状况比戒酒的孕妇更差，而且产妇营养状况不佳会加剧与酒精相关的产前生长限制。我将利用波士顿儿童医院、哈佛医学院、哈佛公共卫生学院和开普敦大学提供的资源，将这些研究添加到先前计划的、NIH资助的大量饮酒孕妇和戒酒者/轻度饮酒者的前瞻性队列研究中，重点关注3个营养领域：1）能量摄入和妊娠期体重增加; 2）铁状况; 3）甲基供体状态（叶酸、维生素B12、胆碱）。这些研究活动与结构化的课程和教学法相结合，将为我提供发展成为一名独立调查员所需的培训，技能和实践经验，该调查员正在进行研究计划，研究产前和产后营养在FASD中的潜在作用。
