This study will examine the effects of Epidiolex among adults who drink alcohol heavily but who are not seeking treatment for their alcohol use. Epidiolex is an FDA-approved formulation of cannabidiol, the primary non-psychoactive constituent of cannabis. Participants in the study will be randomly assigned to take Epidiolex or placebo for 8 days. There are 3 study visits, including a day-long visit in the laboratory.
This purpose of this research study is to collect feedback from participants about a web-based program for opioid misuse and opioid use disorder. Participants will be asked to review web-based content and take part in focus groups (group discussions) and individual interviews to provide feedback on the content. The study team is looking for pregnant women or women who have been pregnant in the past 2 years who misuse opioids or have opioid use disorder, as well as obstetric providers who treat pregnant women with opioid misuse and opioid use disorder to participate.
Transcranial magnetic stimulation (TMS), a non-invasive form of brain stimulation, produces lasting changes in the brain to treat depression and other brain disorders. Emphasis on clinical indications and efficacy has far outpaced a mechanistic understanding of how these changes are produced. In this study, we propose use of the pharmacologic agents d-cycloserine, demonstrated to be safe for human use, to probe in the molecular mechanism of long-term potentiation, the cellular basis of learning and memory. We will measure whether this agent can respectively strengthen the potentiation produced by TMS by looking at the amplitude of motor response (called motor evoked potential or MEP) of the thumb (through electromyography, or EMG).
A better understanding of its mechanism of action promises to optimize our ability to use TMS, and potentially improve duration and degree of response.
The purpose of this study is to better understand the different ways that female Veterans are affected by their experience with military sexual trauma (MST) and to look at the role of several factors that cause some people, but not others, to develop posttraumatic stress disorder (PTSD) or PTSD symptoms. This study is being conducted at the Charleston VA Medical Center, Tuscaloosa VA Medical Center and Atlanta VA Healthcare System. It will involve approximately 150 female Veterans who have experienced MST.
This study will examine the efficacy of intranasal oxytocin versus placebo in combination with Alcohol Behavioral Couples Therapy (ABCT) to reduce alcohol use disorder severity. We will also use observational coding and neuroimaging to examine behavioral and neural mechanisms underlying treatment outcomes.
Candidates for this study may or may not report disturbances in odor perception as their primary reason for seeking treatment at MUSC. This study is designed to collect long term, observational data from patients who are being treated with routine clinical care in health clinics at MUSC. Data from clinical questionnaires will be de-identified and stored in a database.
The purpose of this study is to determine if the medication lofexidine, taken together with buprenorphine or methadone, is more effective at reducing opioid craving, use and stress response than buprenorphine or methadone alone, and to see if this effect is different for men and women. Participants are randomly assigned to add either lofexidine or placebo to their buprenorphine or methadone treatment for five weeks. They return at the end of five weeks to participate in an opioid imagery task and stress task. Throughout the study, participants complete "CREMA" sessions (Cue Reactivity Ecologic Momentary Assessment) using an iPhone app three times a day. These sessions include looking at stressful and neutral pictures and rating stress and craving.
The purpose of the study is to determine if the hormone progesterone affects marijuana users' stress response and marijuana use. Participation lasts approximately three weeks. During the first week, participants are randomly assigned to take either progesterone or placebo and remain abstinent from marijuana. They return at the end of the week to participate in a stress task. Throughout the three weeks, participants complete "CREMA" sessions (Cue Reactivity Ecologic Momentary Assessment) three times a day. These sessions include looking at stressful and neutral pictures and rating stress and craving.
Chronic pain is a serious public health problem with estimates as high as nearly half of the adult population experiencing some form of pain that lasts for more than 6 months. This issue negatively impacts quality of life, is financially burdensome, and has contributed to the opioid crisis in the United States. Therefore, a non-pharmacologic, non-invasive approach for alleviating chronic pain like prefrontal repetitive transcranial magnetic stimulation (rTMS) is an appealing avenue for research into chronic pain management. While rTMS has already been approved for use in treating depression, it has shown promise in treating chronic pain as well. However, there is a debate about which coil designs are most effective and which regions of the brain respond best to rTMS therapy. This study will examine the use of two novel coil designs the H1 coil which is designed to increase activity of the dorsolateral prefrontal cortex and the H7 coil which is designed to decrease activity of the medial prefrontal cortex. To evaluate the efficacy of the two treatment strategies, patients will undergo thermal pain testing before and after the rTMS interventions. The relative efficacy of these two treatment strategies will be useful for establishing rTMS as an effective strategy for chronic pain management and determining the direction for future rTMS research.
The purpose of this study is to develop transcranial magnetic stimulation (TMS) as a novel, non-pharmacologic approach to decreasing pain in individuals with chronic pain. This study will test whether rTMS over the prefrontal cortex can produce a reduction in your perception of pain, your desire to use opiates, and your brain's response to opiate cues. The results of this study will be used to design and develop a large clinical trial of rTMS as an innovative, new treatment option for chronic lower back pain in individuals that may have used chronic opiates.
