Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will examine sleep disordered breathing and sleep quality in participants (ages 12-18) diagnosed with sickle cell disease of any genotype. We will utilize remote peripheral arterial tonometry (PAT) and questionnaires to evaluate difficulties with sleep. PAT assessments will occur remotely in the homes of participants.

Neurocognitive, behavioral, and neuroimaging evaluations will occur on the same day as a routine clinic visit.

Primary Objective:

Evaluate the relationship between nocturnal oxyhemoglobin saturation (SpO2) and neurocognitive functioning (working memory and verbal comprehension) in children (ages 12-18) diagnosed with sickle cell disease controlling for age, genotype, and social vulnerability.

Secondary Objective:

Assess differences in white matter integrity, silent cerebral infarcts, neuroinflammation, and functional connectivity among children (ages 12-18) diagnosed with sickle cell disease with and without sleep disordered breathing after controlling for age.

Assess differences in self- and caregiver-reported mood and pain severity among children (ages 12-18) diagnosed with sickle cell disease with and without sleep disordered breathing after controlling for age.

Exploratory Objectives:

Explore the relationship between nocturnal oxyhemoglobin saturation (SpO2) and neurocognitive functioning (attention, processing speed, verbal memory, visual memory, motor dexterity) in children (ages 12-18) diagnosed with sickle cell disease controlling for age, genotype, and social vulnerability.

Assess the feasibility of an ultraportable ring oximeter (BodimetricsCircul+ Ring) in children (ages 12-18) diagnosed with sickle cell disease.

Assess the concordance between the Circul+Ring with the WatchPAT in children (ages 12-18) diagnosed with sickle cell disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Interested participants will be consented in-person or virtually. Consented participants will be mailed the equipment (WatchPAT and Circul+ Ring) to conduct the remote assessment. Additional questionnaires will also be sent via mail or email for the participant to complete prior to collecting data on sleep behaviors. After receiving the questionnaires and equipment, a virtual session will be conducted with the participant to provide education on how to use the equipment and complete the included questionnaires. Participants will wear the WatchPAT and Circul+ Ring overnight for three days and data will be captured remotely. After wearing the devices for three consecutive nights, the participant will attend a research visit within approximately the next two weeks where they will complete performance based neurocognitive assessments, behavioral rating forms, and neuroimaging.
