Pediatric Obstructive Sleep Apnea and Surgical Timing – A Hypothesis Translational Model

This project will be recapitulating pediatric obstructive sleep apnea (OSA) using a preclinical murine model to understand the neurocognitive sequelae of the disease. The project team is using a top-down approach involving neurobehavior, synaptic staining and quantification, and piezoelectric field placement to help drill down which area of the brain to focus on in understanding deficits in humans. By using a preclinical model, the team hopes to be able to provide better answers for OSA in children with neurocognitive disorders.

Pilot Study of Locus Coeruleus Neuroimaging with Sleep and Alzheimer’s Disease Biomarkers

In this project, the team is applying non-invasive ultra-high field 7T MRI to identify the locus coeruleus (LC) in cognitively normal elderly. This brain structure contributes to the sleep/wake cycle, memory processing and is also susceptible to early Alzheimer’s Disease (AD) pathology. The aim of this work is to assess the feasibility of this novel neuroimaging technique in older individuals with known sleep fragmentation/obstructive sleep apnea measures as well as AD biomarkers such as cerebrospinal fluid total-tau and amyloid beta 42.

Sleep Apnea and Influence of Obesity across the Atrial Fibrillation Trajectory

Despite experimental and our epidemiologic data implicating sleep disordered breathing (SDB) as a clinically novel atrial fibrillation (AF) trigger, the interplay of SDB and obesity across the AF continuum remains a critical knowledge gap. The project proposes to identify SDB, obesity and metabolic determinants across AF subtypes by examining paroxysmal, persistent and longstanding persistent AF groups and matched controls with collection of innovative, state-of-the art cardiac imaging of visceral adiposity and proteomics profiles.

Sleep-related Attention Bias in Older Adults: Impact of Insomnia Symptoms and Sex

Increased attention to sleep-related stimuli, or “sleep-related attentional bias” is common in insomnia. However, sleep and sex-specific mechanisms underlying this phenomenon are poorly understood. In this study, the project team will compare visual vs. auditory related attentional bias, evaluate the contributions of self-reported, actigraphic and polysomnographic sleep to these biases, and examine differences between men and women. Findings may identify sex-specific targets for behavioral insomnia intervention such as cognitive behavioral therapy or stimulus desensitization.

Imaging the Living Human Retina to Measure Circadian Sensitivity

Circadian clocks in the retina oscillate independently and modulate entraining signals to the central circadian pacemaker. The phase and amplitude relations between the retinal and central pacemaker have not been defined in humans, while breakdowns of these relations may underlie circadian disease. The principal investigator will evaluate this hypothesis by probing and imaging how living human photoreceptors vary in sensitivity across 24-h timescales, in participants who are healthy, who have sleep phase disorders, or shiftwork disorder.

A Closer Look at the Effect of Oral Appliance Therapy on Blood Pressure in Sleep Apnea

The proposed research investigates the effect of oral appliance therapy on blood pressure in OSA. Past studies on this topic show modest-to-no effect. The project team believes the source of this inconsistency is imprecise characterization of the physiological consequences of OSA, such as hypoxia or sympathetic surges. The proposed research applies two advanced metrics to identify OSA patients at risk for cardiovascular disease and investigate the effect of oral appliances on blood pressure in this group.

Association between the Sleep Apnea Specific Hypoxic Burden (SASHB) with Incident Neurocognitive Impairment

OSA is a common condition associated with neurocognitive impairment. This study aims to determine if the sleep apnea-specific hypoxic burden can identify individuals with OSA that have an increased risk of prevalent and incident neurocognitive impairment in two community-based cohorts, available on the National Sleep Research Resource. The expected results will provide additional information for clinicians who attend patients with OSA by incorporating this measure in the precision-medicine approach.

Multivariate Data-driven Approach in Identifying Sleep Profiles of Chronic Insomnia
Sponsored by Eisai, Inc.

Chronic insomnia has a high degree of heterogeneity, making it difficult to identify a single robust biomarker. This project proposes to use a multidimensional approach in defining chronic insomnia profiles by extracting sleep profiles characterized by a combination of subjective (sleep diaries, questionnaires) and objective (polysomnography) sleep measures using a data-driven approach from datasets of individuals with insomnia. It might explain insomnia in a holistic manner but also lead to personalized therapeutic approach for chronic insomnia.

Piloting an Adaptation of Cognitive Behavioral Therapy for Insomnia for Shift Workers (CBTI-Shift)

Insomnia is common among shift workers. However, the gold standard treatment (cognitive-behavioral therapy for insomnia, CBTI) has rarely been tested among shift workers and is not optimized for their unique schedules and challenges. This study will pilot test the feasibility and acceptability of CBTI-Shift, which adapts and personalizes CBTI for shift workers. The long-term objective of this research is to improve the sleep, health and wellbeing of shift workers using an evidence-based treatment of insomnia.

Application of Machine-Learning to Assess Heterogeneity of Continuous Positive Airway Pressure (CPAP) Effect on Major Adverse Cardiovascular Events in the ISAACC Trial (Impact of Sleep Apnea in the Evolution of Acute Coronary Syndrome)

Obstructive Sleep Apnea (OSA) is associated with incident cardiovascular (CV) disease, however the impact of OSA treatment on CVD events is indeterminate. Furthermore, there is a growing body of evidence suggesting OSA may be cardioprotective. Earlier studies did not discover significant effects of CPAP treatment on CV events, probably because of heterogeneity of CPAP effect in patients with varying baseline clinical characteristics resulting in the masking of treatment effects. We therefore propose a subtyping approach using machine learning to identify subgroups of patients in the ISAACC trial that may benefit or are perhaps harmed from CPAP therapy.

Adapting CBT-I for and with Adolescents

Insomnia is common in adolescents, yet most insomnia treatments have been developed for adults. We propose to adapt an efficacious adult treatment (Cognitive Behavioral Therapy for Insomnia; CBT-I) for adolescents. To develop this adapted protocol (Cognitive Behavioral Therapy for Insomnia in Teens; CBT-IT), we will conduct virtual groups with key stakeholders, including adolescents, parents and providers. We will then conduct a randomized controlled trial of CBT-IT to assess its efficacy in treating insomnia in adolescents.

Testing the Efficacy of Telehealth Brief Behavioral Treatment for Insomnia for Socioeconomically Disadvantaged Adults

Despite the prevalence of insomnia among socioeconomically disadvantaged adults, few insomnia interventions have targeted this group. We will conduct a randomized trial of 64 socioeconomically disadvantaged adults with insomnia to determine the efficacy of an adapted tele-Brief Behavioral of Insomnia (BBTI). We hypothesize that compared to patients randomized to an attention-control, those randomized to BBTI will have greater improvements in insomnia symptoms at three months. This project will advance insomnia treatments for socioeconomically disadvantaged adults.

A Randomized Controlled Trial Comparing Home-Based Intensive Sleep Retraining to Online CBT-I and The Combination for the Treatment of Chronic Insomnia Disorder

This randomized controlled trial will compare the efficacy of two remote therapeutics, namely THIM (administers Intensive Sleep Retraining) and SHUT-I (online CBT-I program), against a control condition for treating Chronic Insomnia Disorder. The study will also evaluate the combination of remote therapies (THIM followed by SHUT-I) to determine whether this novel approach leads to greater benefits than either treatment alone. The trial will inform clinical decision-making about choice of therapy and build a case for health insurance-funded remote therapy options for insomnia.

Innovations in wearable technology for correcting circadian misalignment in shift work disorder

Shift workers are critical to essential all 24-hour operations; however, many never adapt to the inverted sleep-wake schedule, leading to circadian misalignment and shift work disorder (SWD). One critical barrier to treating SWD has been a lack of clinically feasible approaches to quantifying circadian misalignment. To address this, we will test the use of Apple Watch in conjunction with a consumer-oriented mobile application (SHIFT) to assess and correct for circadian misalignment in night shift workers.

SLEEP-E: Sleep Education for Eating Disorder Treatment Providers

Although insomnia is common in eating disorders (EDs), many providers are not trained to treat these symptoms. The first phase of this project is to characterize ED treatment providers’ behavioral sleep medicine training and use of evidence-based treatments. The second phase is to develop and test a free web-based training for ED treatment providers on insomnia assessment and treatment. Following grant completion, our team will make the SLEEP-E training publicly available.

Global Adaptation: Designing Sleep for Shift Work Students

Cross-cultural fluency and adaptive thinking are critical for thriving in a global university and workforce. But, with travel restrictions, students are too tired to reach their potential because the international courses and immersion they seek happen during the middle of their night. Therefore, we will deliver “shift work education” workshops grounded in powerful, evidence-based strategies for night shift workers to help students effectively adapt their sleep and elevate their performance in any global context.

CHI PAP: CommunityHealth Initiative for Patient-Centered Apnea Protocols

Low-resource individuals are at increased risk for sleep disorders, including sleep disordered breathing, but have traditionally been excluded from standard-of-care evaluation and treatment due to lack of infrastructure for the provision of testing, CPAP devices, and supplies to uninsured populations. CHI-PAP entails a 4-phase care process model for bridging these types of gaps in sleep health among low-resource patients receiving care at CommunityHealth, a well-established free clinic on Chicago’s Near-West Side.

Sleep Apnea Disaster Preparedness Campaign

During February 2021, exceptionally cold weather caused millions of people in Texas to lose electrical power for several days. Through video interviews, ASAA proposes to document the still-fresh, first-hand stories of people in the Rio Grande Valley who were not able to use their therapy during the Texas power outage. ASAA will conduct video interviews with six residents of the RGV to develop a powerful bilingual (English and Spanish) multi-media public awareness campaign around disaster preparedness for sleep apnea patients. Such guidance will assist patients to plan ahead for disasters, mitigating negative health impacts and possibly saving lives.
