This Mentored Patient-Oriented Research Career Development Award proposes a program of tailored mentorship, focused research, didactics and coursework to provide the candidate with the training in sleep medicine and perinatal neuroendocrine functioning necessary for independence as an investigator. Candidate. The candidate's background and foundation in clinical research make her well-poised for this award. She completed her Ph.D. in clinical psychology at the University of Alabama, where she received training rooted in the scientist-practitioner model. An emerging interest in sleep and mood led her to pursue a postdoctoral fellowship at the University of Michigan, where she began to develop a niche in behavioral sleep medicine and perinatal mental health. She was recently appointed to the faculty of the Department of Psychiatry at the University of Michigan. Her goal is to receive additional training in sleep medicine and perinatal neuroendocrinology. The candidate has identified two key training objectives necessary to achieve full independence as a researcher: (1) experience in sleep physiology (including assessment and treatment of sleep-disordered breathing in pregnancy) and (2) neuroendocrinology in pregnancy. Environment. The proposed project will take place within the University of Michigan Department of Psychiatry and the Sleep Disorders Center. Both departments have an extensive history of close collaboration with the Department of Obstetrics and Gynecology. The fifth largest research university in the United States, the University of Michigan provides extensive resources and a rich research environment. The candidate will have access to the large, accredited Sleep Laboratory within the Sleep Disorders Center, the well-established perinatal recruitment infrastructure within the Women's Mental Health and Infants Program (in collaboration with the Department of Obstetrics), and resources provided by the CTSA-funded Michigan Institute for Clinical and Health Research. The proposed primary mentor, Ronald Chervin, M.D., M.S., is a well-funded, highly productive expert in sleep-disordered breathing who has more than 20 years of experience in sleep medicine and a long history of mentoring K awardees and junior faculty. Two carefully selected co-mentors, physiologist Louise O'Brien, Ph.D., M.S., and psychiatrist Juan Lopez, M.D., will provide focused training in perinatal sleep and neuroendocrinology, respectively. The proposal is also bolstered by a tailored consultant team. Research. The goal of this application is to understand the contribution of sleep-disordered breathing (SDB) to one of the most common and debilitating adverse pregnancy outcomes, perinatal depression. It is our hypothesis that positive airway pressure (PAP) treatment of SDB in pregnant women with comorbid depression will result in significant reductions in depressive symptoms and improved neuroendocrine functioning. This proposal will leverage our unique expertise with PAP for SDB in pregnancy and adverse pregnancy outcomes, including perinatal depression. The rationale is that a better understanding of the role of SDB and the impact of PAP treatment on perinatal depression will allow for development of targeted and critically-timed interventions which may have long-term benefits for both women and their offspring. We plan to test our hypothesis by randomly assigning 50 women with SDB to receive either positive airway pressure treatment (PAP group) or treatment as usual in obstetrics (non-PAP group). The following specific aims will be tested:
AIM 1 : Determine the impact of PAP treatment on prenatal depressive symptoms in pregnant women with SDB and depression.
AIM 2 : Identify the contribution of PAP treatment on the HPA axis in pregnant women with SDB and depression. An exploratory aim is to assess associations between PAP treatment and adverse pregnancy and neonatal outcomes in women with depression and SDB. With respect to expected outcomes, the proposed work will demonstrate that SDB during pregnancy plays a role in perinatal depression, and that treatment of SDB during pregnancy will ameliorate depressive symptoms and HPA axis functioning, and improve pregnancy and neonatal outcomes. Such findings are expected to have an important positive impact, because they will further our understanding of the role of SDB in adverse pregnancy outcomes and reduce the burden of the most common and debilitating adverse outcomes experienced by pregnant women. This will have long term health benefits for both women and their offspring. Summary. The proposed K23 will provide key additional training for a promising early investigator to become a clinical researcher in perinatal sleep medicine. The project will also address important, testable questions about the relationships between a common sleep disorder and the debilitating adverse pregnancy outcome of perinatal depression, a major public health concern.
A major public health concern, perinatal depression affects nearly 800,000 women annually and is one of the most common and debilitating adverse pregnancy outcomes. Sleep-disordered breathing is a known contributor to depressive symptoms in non-pregnant adults. This project seeks to understand the impact of sleep-disordered breathing and its treatment on perinatal depression to address the critical need for rapid- acting, accessible, non-pharmacological treatments for this population.
