项目摘要
DESCRIPTION (provided by applicant): This proposal for a Mentored Patient-Oriented Research Career Development Award (K23) application is divided into didactic, applied clinical and translational research components. The didactic component will provide educational experiences to allow the principal investigator to design, conduct, and analyze patient-oriented research. A detailed instructional plan is described in the application. The clinical and translational research training component will provide the candidate an opportunity to work closely with experienced clinical and basic science investigators. The project will combine 1) in vivo, retrospective assessment of the severity of any postradiation dental lesions as related to factors such as radiation field parameters, the radiation dose to which teeth were exposed, and the use of salivary gland radiation protector drugs; 2) in vitro chemical, mechanical, and morphologic analyses of structure and properties of in vivo irradiated teeth as compared to non-irradiated teeth; 3) the structure/property relationships will be used in finite element modeling of the stress distribution within irradiated teeth under simulated functional loading conditions; 4) developing the infrastructure and acquiring the preliminary data to continue the investigation as a prospective, longitudinal clinical trial for future grant applications in order to correlate the initiation and progression of post-radiation dental lesions to additional clinical factors such as xerostomia and occlusal patterns, as well as radiation dose, field parameters, and the use radiation protector drugs. This project will enable the candidate to obtain research skills in the following areas: 1) retrospective and prospective methodology in the clinical evaluation of patient factors related to therapeutic radiation-induced dental lesions; 2) laboratory evaluation of the associated changes in the structure and properties of teeth exposed to therapeutic radiation; 3) finite element calculation and modeling of stress distribution patterns that develop in these teeth under simulated functional loading. By completing the objectives outlined in the project, Dr. Walker will develop skills necessary to function as an independent clinical researcher and have the opportunity to collaborate with basic scientists to gain insight into how laboratory analyses can be incorporated into patient-based investigations. A key strength of this project is the associated feedback mechanism that relates the clinical problem to both clinical and laboratory data, the integration of scientific principles into clinical practice.
描述(由申请人提供):本指导性患者导向研究职业发展奖(K23)申请提案分为教学、应用临床和转化研究部分。教学部分将提供教育经验,使主要研究者能够设计、进行和分析以患者为导向的研究。申请中描述了详细的教学计划。临床和转化研究培训部分将为候选人提供与经验丰富的临床和基础科学研究人员密切合作的机会。该项目将结合 1) 对任何放射后牙齿病变的严重程度进行体内回顾性评估,这些损害与辐射场参数、牙齿暴露的辐射剂量以及唾液腺辐射保护药物的使用等因素有关; 2) 与未辐照牙齿相比,对体内辐照牙齿的结构和特性进行体外化学、机械和形态学分析; 3) 结构/性能关系将用于在模拟功能负载条件下辐照牙齿内应力分布的有限元建模; 4) 开发基础设施并获取初步数据,以继续作为未来拨款申请的前瞻性、纵向临床试验进行调查,以便将放射后牙科病变的发生和进展与其他临床因素(如口干症和咬合模式)联系起来,以及辐射剂量、场参数和使用辐射防护药物。该项目将使候选人获得以下领域的研究技能:1)对与治疗性放射引起的牙科病变相关的患者因素进行临床评估的回顾性和前瞻性方法; 2) 对暴露于治疗辐射的牙齿结构和特性的相关变化进行实验室评估; 3) 对这些牙齿在模拟功能负载下产生的应力分布模式进行有限元计算和建模。通过完成该项目中概述的目标,沃克博士将培养作为独立临床研究人员所需的技能,并有机会与基础科学家合作,深入了解如何将实验室分析纳入基于患者的研究。该项目的一个关键优势是将临床问题与临床和实验室数据相关联的相关反馈机制,以及将科学原理融入临床实践。
