项目摘要

PROJECT SUMMARY Dr. Hibbs proposes a patient-oriented research and mentorship program focusing on prematurity-associated pulmonary morbidity. She has a strong track-record for POR research and mentorship and availability of future mentees from junior faculty and trainees at Rainbow Babies and Children's Hospital (RBC) and CWRU; she will integrate mentees in the newly proposed project as well as other currently funded local and multi-center studies. Longer term respiratory morbidity and neurodevelopmental delay are major consequences of preterm birth. In the proposed study, we seek to characterize the association between immature respiratory control, manifesting as intermittent hypoxia (IH), and later respiratory and neurodevelopmental morbidity in a cohort of preterm infants less than or equal to 30 weeks' gestation. This proposal is a two-year follow-up study of the Pre-Vent Case Western Reserve (CWRU) site protocol, and represents a unique opportunity to pair longer-term clinically relevant outcomes, as measured by validated questionnaires, with an already-funded study using sophisticated techniques to capture and analyze early life IH events. Our hypotheses are that IH episodes at one week and one month of life are significantly associated with recurrent wheezing, sleep disordered breathing, and neurodevelopmental delay. In prior studies we have demonstrated that apnea almost always precedes desaturation in preterm infants and have documented a novel association between retinopathy of prematurity, and both the duration of IH events and the time interval between IH events. From these data we speculate that it is not only longer and more frequent IH events, but also distinct time interval of at least one minute between IH events, that will be associated with long-term clinical morbidities. We provide additional retrospective data that IH is associated with wheezing disorders, as well as a remarkable track record for both meeting enrollment goals and effective follow-up in prior clinical studies.

项目摘要 Hibbs博士提出了一个以患者为导向的研究和指导计划早产相关的肺部发病率。她有强大的田径记录以及彩虹的初级教师和学员的未来受训者的指导和可用性婴儿和儿童医院（RBC）和CWRU；她将将受训者纳入新的拟议的项目以及其他当前资助的本地和多中心研究。长期呼吸道发病率和神经发育延迟是早产。在拟议的研究中，我们试图表征未成熟之间的关联呼吸控制，表现为间歇性缺氧（IH），后来呼吸道和在不到或等于30周的早产儿中的神经发育发病率妊娠。该提案是对前案例西部储备的两年后续研究（CWRU）站点协议，代表了与长期相关的独特机会通过经过验证的问卷来衡量的结果，并通过一项已资助的研究使用捕获和分析早期生活的精致技术。我们的假设是IH 一周和一个月的生命的发作与经常性显着相关喘息，呼吸失调和神经发育延迟。在先前的研究中，我们有证明呼吸暂停几乎总是先于早产儿的饱和度，并且具有记录了早产视网膜病与IH的持续时间之间的新型关联事件和IH事件之间的时间间隔。从这些数据中，我们推测它不仅是更长，更频繁的IH事件，但也不同的时间间隔至少为一分钟在IH事件之间，这将与长期临床病毒有关。我们提供 IH与喘息疾病相关的其他回顾性数据以及达到入学目标和先前临床的有效随访的杰出记录研究。
