项目摘要
ABSTRACT
The proposed training grant is designed to advance the academic career of Dr. Vaishnavi Kundel, MD, by
building upon her strong background in clinical sleep medicine to engage in patient-oriented research, and
develop expertise in exploring the role of sleep in cardiometabolic disease risk. Through this proposal, she will
obtain multidisciplinary training to investigate chronic sleep deprivation and sleep irregularity as potentially
modifiable risk factors for atherosclerosis and visceral adiposity measured using multi-modality imaging - hybrid
18fluorodeoxyglucose (FDG) PET/MRI. Research plan: The proposed research builds on Dr. Kundel's pilot
studies funded by the AASM. The aims are to determine whether habitual short sleep duration and sleep
irregularity are associated with increased vascular inflammation and visceral adiposity (which is strongly linked
to increased CVD risk), independent of OSA (often a confounder in these associations). We will utilize multi-day
actigraphy to collect objective sleep metrics, and PET/MRI to measure vascular inflammation and visceral
adipose tissue (VAT) metabolic activity (a novel marker of adipose tissue inflammation) in the recruited patients.
With successful completion of the proposed training and research, we hope to underscore the role of chronic
sleep deprivation and sleep irregularity in cardiometabolic risk, establishing an index of imaging biomarkers for
future research. Moreover, the results will provide direction for future (R01) proposals - laying the groundwork
for developing multidisciplinary collaborations to elucidate mechanisms by which sleep modulates inflammation,
with a long-term goal of identifying biomarkers of early cardiovascular risk in this subset of patients, and
designing sleep extension studies. Career Development: Dr. Kundel's training plan features an outstanding
research environment at the Icahn School of Medicine at Mount Sinai along with nationally renowned mentors
and advisors with complimentary expertise. Her primary mentoring team comprises of (a) Dr. Neomi Shah, MD,
MPH, MS (expert in obstructive sleep apnea [OSA] and cardiovascular (CV) diseases, and application of
advanced cardiovascular imaging in OSA) (b) Dr. Indu Ayappa, PhD, (recipient of a mentored K-24 award, with
expertise in OSA, sleep physiology, and use of actigraphy for objective sleep assessments) (c) Drs. Zahi Fayad
and Philip Robson, PhD (experts in use of multimodality imaging for assessment of atherosclerosis and organ
system biology). Her training features a combination of carefully designed coursework and practical experiences
in 1) actigraphy for comprehensive assessments of objective sleep metrics 2) multi-modality cardiometabolic
imaging 3) clinical study design and patient-oriented research 4) training in biomarker science for future
proposals. Together, her mentors and advisors have a successful track record of mentoring junior faculty in
career development awards, with extensive collaborations and grant portfolios to provide a solid foundation for
Dr. Kundel's present proposal, and ultimate success in developing into an independent investigator.
摘要
拟议的培训补助金旨在通过以下方式促进Vaishnavi Kundel博士的学术生涯:
建立在她在临床睡眠医学的强大背景,从事以病人为导向的研究,
在探索睡眠在心脏代谢疾病风险中的作用方面发展专业知识。通过这一提议,她将
获得多学科培训,以调查慢性睡眠剥夺和睡眠不规律,
使用多模态成像测量动脉粥样硬化和内脏肥胖的可改变风险因素-混合
18氟脱氧葡萄糖(FDG)PET/MRI。研究计划:拟议的研究建立在Kundel博士的试点基础上。
由AASM资助的研究。目的是确定是否习惯性短睡眠时间和睡眠
不规则性与血管炎症和内脏肥胖增加有关(这与
增加CVD风险),独立于OSA(通常是这些关联的混杂因素)。我们将利用多天
活动记录仪收集客观的睡眠指标,PET/MRI测量血管炎症和内脏
脂肪组织(VAT)代谢活性(脂肪组织炎症的新标志物)。
随着拟议的培训和研究的成功完成,我们希望强调慢性病的作用。
睡眠剥夺和睡眠不规律在心脏代谢风险中的作用,
未来的研究。此外,研究结果将为未来的(R01)提案提供方向-奠定基础
为了发展多学科合作来阐明睡眠调节炎症的机制,
其长期目标是确定该患者亚组中早期心血管风险的生物标志物,以及
设计睡眠延长研究。职业发展:Kundel博士的培训计划具有出色的
沿着有全国知名的导师,
和具有互补专业知识的顾问。她的主要指导团队包括:(a)Neomi Shah博士,医学博士,
MPH,MS(阻塞性睡眠呼吸暂停[OSA]和心血管(CV)疾病专家,以及
(B)Indu Ayappa博士(K-24指导奖获得者,
(c)Zahi Fayad博士
和Philip Robson博士(使用多模态成像评估动脉粥样硬化和器官损伤的专家)
系统生物学)。她的培训结合了精心设计的课程和实践经验
在1)用于客观睡眠指标的综合评估的体动记录2)多模态心脏代谢
成像3)临床研究设计和以患者为导向的研究4)未来生物标志物科学的培训
提案总之,她的导师和顾问有一个成功的指导初级教师的记录,
职业发展奖,与广泛的合作和赠款组合,提供坚实的基础,
博士昆德尔目前的建议,并最终成功地发展成为一个独立的调查员。
