 DESCRIPTION (provided by applicant): My long-term goal is to become an independent researcher in cardiovascular epidemiology with a focus on the morbidity burden associated with cerebrovascular diseases, particularly stroke. I will use this Mentored Career Development award (K01) to fulfill a series of training objectives which build upon my prior skills, but also expand my expertise in ways which are essential to accomplishing my long-term goal. These include: learning to measure and analyze longitudinal stroke outcomes data; developing skills to assess, characterize, and measure white matter hyperintensity volume (WMHV) and cerebral microbleeds (CMBs) from magnetic resonance imaging (MRI) scans; learning about the design, conduct, and analysis of randomized clinical trials; and acquiring skills in mediation analysis techniques. To achieve my training objectives, I have assembled a comprehensive and complementary mentorship team which has worked together and with me for many years. My training objectives will also allow me to develop the skills needed to establish new datasets within ongoing studies during this award period. These subcohorts are necessary to achieve the research goals of the K01 and will provide preliminary data for future grant applications for independent research funding. I will apply my training to several important research questions during this K01 award. Recently, there has been growing interest in the role that vitamin D as well as omega-3 fatty acids play in the development of cardiovascular disease events. Given the high morbidity burden of stroke, determining the effect of these supplements on stroke outcomes is very important. The NIH sponsored VITamin D and OmegA-3 TriaL (VITAL) is an ongoing randomized, double blind trial testing vitamin D3 and omega-3 fatty acid supplementation in the primary prevention of cancer and cardiovascular disease. I will leverage this ongoing trial and collect additional data on stroke outcomes that would not otherwise be collected by the parent study. In addition, there is growing interest in discovering risk factors fr overall subclinical cerebrovascular disease burden in the brain as measured by WMHV and CMBs. Because WMHV and CMBs are associated with stroke outcomes, understanding risk factors associated with WMHV and CMBs in ischemic stroke patients may identify strategies to reduce the morbidity burden of stroke. I will collect MRI scans performed as part of routine medical care in participants with an ischemic stroke to create a database of WMHV and CMBs in VITAL and the Women's Healthy Study (WHS), a completed trial of the effects of low dose aspirin and vitamin E in the primary prevention of cardiovascular disease and cancer with ongoing observational follow-up. By using data from both VITAL and WHS, I will have the unique opportunity to study how a wide variety of cardiovascular disease risk factors impact WMHV and CMBs in stroke patients. The training, mentorship, research experience, and opportunity to establish new subcohorts provided by this K01 award will allow me to achieve my long-term career goal of becoming an independent research in cardiovascular disease epidemiology.

 描述（由申请人提供）：我的长期目标是成为心血管流行病学的独立研究员，重点关注与脑血管疾病（特别是中风）相关的发病负担。我将利用这一指导职业发展奖（K01）来实现一个目标。一系列的培训目标建立在我之前的技能的基础上，同时也扩展了我对实现我的长期目标至关重要的专业知识，其中包括：学习测量和分析纵向中风结果数据；培养评估的技能；通过磁共振成像 (MRI) 扫描来表征和测量白质高信号体积 (WMHV) 和脑微出血 (CMB)；了解随机临床试验的设计、实施和分析，并掌握中介分析技术的技能。为了实现我的培训目标，我组建了一个全面且互补的指导团队，他们与我一起工作了很多年。我的培训目标也将使我能够在这些子群体中培养在正在进行的研究中建立新数据集所需的技能。是必要的为了实现 K01 的研究目标，并将为未来的独立研究资助申请提供初步数据。最近，人们对维生素 D 的作用越来越感兴趣。鉴于中风的高发病率，确定这些补充剂对中风结果的影响非常重要。 (VITAL) 是一项正在进行的随机、双盲试验，测试维生素 D3 和 omega-3 脂肪酸补充剂在癌症和心血管疾病一级预防中的作用，我将利用这项正在进行的试验并收集有关中风结果的其他数据，而这些数据原本不会收集。此外，人们越来越有兴趣发现通过 WMHV 和 CMB 测量的大脑总体亚临床脑血管疾病负担的危险因素，因为 WMHV 和 CMB 与中风结果相关，因此了解与中风相关的危险因素。缺血性中风患者的 WMHV 和 CMB 可能会确定降低中风发病负担的策略。我将收集作为缺血性中风参与者的常规医疗护理一部分进行的 MRI 扫描，以在 VITAL 和女性健康中创建 WMHV 和 CMB 数据库。研究 (WHS) 是一项针对低剂量阿司匹林和维生素 E 在心血管疾病和癌症一级预防中的效果的完整试验，并使用 VITAL 和 VITAL 的数据进行持续观察性随访。 WHS，我将有独特的机会研究各种心血管疾病危险因素如何影响中风患者的 WMHV 和 CMB。K01 奖项提供的培训、指导、研究经验和建立新小组的机会将使我能够实现我的长期职业目标，成为心血管疾病流行病学的独立研究人员。
