3 Clinical Trials for Various Conditions
Opioid use disorder (OUD) is a chronic relapsing disorder and is well-known for its high-risk rate of overdoses and death. In OUD, sleep and circadian disruptions are highly prevalent, interfere with opioid maintenance treatment outcomes and increase the risk of relapse. So far, commonly used pharmacological sleep treatments fail to improve sleep or decrease illicit drug use in OUD. Thus, there is an urgent need to fill this research gap. Previous work showed that OUD patients who were receiving opioid agonist treatment (MOUD+) exhibited greater irregularity of sleep-wake cycle. In OUD patients, sleep-wake irregularity was associated with years of heroin use and low light exposure. Bright light therapy (BLT) is a very promising circadian/sleep intervention for several sleep, psychiatric and neurological disorders. BLT improved circadian, sleep outcomes and negative mood. In a pilot study, BLT improved objective and subjective sleep in patients with alcohol use disorder. Here investigators proposed an intervention study for MOUD+ patients to determine effects of BLT as an adjunct treatment on sleep and circadian outcomes including endogenous circadian rhythm, rest-activity rhythm and sleep neurophysiology (Primary objectives); and to determine effects of BLT on brain function and on clinical outcomes including negative affect, craving and illicit drug use and whether changes in sleep and circadian rhythm mediate the BLT effect on brain recovery and clinical outcomes (Secondary objectives). Fifty MOUD+ will be assigned either to bright light or to dim light group for 2 weeks. The groups will be matched for age, sex, race and OUD medication (Methadone vs Buprenorphine). The study will run throughout the year such that it occurs during all seasons. Light exposure will be measured with light sensor for additional control. All MOUD+ participants will have a daily 30-min light exposure (bright or dim blue light) in the morning after their habitual wake-up time and will be asked to avoid evening light before bed. Dim light melatonin onset, accelerometer, sleep EEG and questionnaires will be used to measure objective and subjective sleep and circadian outcomes. For brain function, cue-reactivity task will be used to assess brain activation during drug craving. Resting state functional connectivity and brain state dynamics will be assessed by rsfMRI. Mood, opiate craving and illicit drug use will be assessed. All measures will be repeated before and after the treatment. Investigators expect that BLT would normalize sleep and circadian outcomes, attenuate impairments in brain functions and result in better clinical outcomes. If successful, light therapy will provide add-on benefits to opioid agonist therapy and facilitate OUD recovery process.
The purpose of this study is to determine if medication designed to improve memory will help patients with Multiple Sclerosis (MS) who are experiencing memory problems using fMRI to track brain activity.
We are looking for volunteers who suffer from acute migraine (\<14 episodes per month) to participate in a 2-visit brain imaging research study. The goal of the study is to observe the effect of acute administration of Treximet during a migraine episode on the pain pathways of the migraine brain. Visit 1 will consist of 1 hour, where participants will be signing the informed consent form, completing questionnaires, meeting with the study physician, and having QST (sensory testing to determine individual pain thresholds to a heat stimulus) performed. Visit 2 will occur during a migraine episode. Volunteers will be asked to contact the study team at the first onset of a migraine. Upon arrival at Visit 2, individuals will be given an IV for blood draws. Once these the IV is in place, subjects will enter the MRI and be asked to stay very still. Scanning will occur for about 20 minutes, and then subjects will be given a Treximet tablet to combat their migraine. More scanning will follow Treximet administration. Some scans will have no stimulation, and others will apply a heat stimulus that subjects will rate using a pain scale. Seven 5-mL blood samples will be drawn throughout the duration of the MRI session. Both Visit 1 and Visit 2 will be compensated.
