This study will examine genetic factors that contribute to the different ways people feel after consuming cannabis. People that use cannabis at least 4 days per week will participate in a study involving 1 in-person visit followed by a 5-day remote assessment period. The in-person visit will determine if an individual is eligible for study participation and their blood will be drawn to assess genetics. During the remote assessment period, participants will complete multiple short surveys per day describing their feelings and their recent cannabis use.

An international research registry called the CorEvitas International Adolescent Alopecia Areata (AA) Registry (the "CorEvitas Registry"). This observational registry studies adolescent patients with AA between 12-17 years of age under the care of a dermatology provider diagnosed with moderate to severe alopecia areata.

This is a 16-week-long treatment study for people with Alcohol Use Disorder who want to stop or cut down their drinking. The purpose of this study is to determine whether an investigational medication, TMP-301, affects craving for alcohol and/or alcohol drinking while taking the study drug. Participants will be randomly assigned to TMP-301or a matched placebo

The TEAM-HF trial aims to find out whether measuring pressure in the heart and lungs using an implantable device called a CardioMEMS can help identify heart failure patients who are getting worse and may benefit from earlier treatment with a heart pump called an LVAD. It also seeks to determine if patients with advanced heart failure, who are not on IV medications for their heart failure but still have high pressures in their heart and lungs can improve with LVAD therapy.

This is an international, multicenter, study that will not prescribe elafibranor. It is designed primarily to collect data and assess real-world effectiveness of treatment with elafibranor 80mg/day on adult patients with PBC, and to describe the safety of this treatment and its impact on their quality of life, over a period of 24 months.

We are testing a 2D system designed to help people with Parkinson's disease practice their speech. In this study, participants will speak with a virtual character, called an embodied conversational agent, using a laptop. Our goal is to see if this technology is helpful and easy to use for people with Parkinson's disease to use. This research will help us learn whether using virtual characters at home could support long-term speech improvements.

The purpose of this study is to learn more about late-onset epilepsy of unknown etiology (LOEU), which is defined as an onset of seizure activity in late life (age 60 or above) without a clear neurological cause. That is, many older adults will experience seizures due to neurological conditions such as stroke, brain injury, tumor, or infection. However, other individuals will also develop seizures with no identified cause.

Participation entails a single study visit lasting 2-3 hours including a fasting blood draw, completion of standardized cognitive testing, and several questionnaires. The goals of the study include to examine blood markers that can help us to better understand the condition including dementia risk, and how these markers may impact the clinical presentation of the condition. No interventions/treatments are included with this study.

This study aims to evaluate the safety and tolerability of ARQ-151 cream 0.05% in infants with mild to moderate eczema after daily application for four weeks. ARQ-151 contains the active ingredient roflumilast, which reduces the activity of the enzyme PDE-4 involved in inflammation. Since eczema is an inflammatory skin disease, ARQ-151 could potentially help treat this condition.

Eligible participants (ages 18+ whom have daily cigarette use) will attend an in-person assessment (though some aspects of the study, including consent, can be completed remotely). Participants will submit a breath sample for assessment of expired carbon monoxide. Approximately 5-7 days after completion of the in-person assessment, participants will meet with research staff. A medical clinician will meet with the participant to present a smoking cessation treatment recommendation along with resources. Participants will also complete surveys to assess their treatment preferences, motivation, and self-efficacy following receipt of the recommendation.

This is a research study to help see if a new interview for posttraumatic stress disorder (PTSD), called the Revised Clinician-Administered PTSD Scale for DSM-5, or the CAPS-5-R for short, is accurate and reliable for veterans. By doing this study, we hope to learn if the CAPS-5-R can be used in VA to diagnose PTSD. Participation will all be done remotely. Joining this study will involve (1) completing some questionnaire measures and (2) completing an interview remotely by videoconference over 2 days at most.

Participants must be Veterans, aged 18 or older in the Ralph H. Johnson VA Health Care System who have experienced trauma or at least one PTSD symptom.
