In the current study, we will recruit individuals using addictive drugs (cocaine, cannabis, opioids, or methamphetamine) and non-drug use control individuals. The study participants will fill out questionnaires, consent, and donate samples (urine, saliva, nasal swab, and blood). These samples will be used to study the causes of unhealthy conditions during drug uses. Our goal is to prevent or treat the drug-associated unhealthy conditions (i.e., anxiety, memory impairment).

This study examines how parents and adolescents communicate about alcohol and marijuana during mid-to-late adolescence, a period marked by rising substance use risk. Although many parents want to reduce harm, they often receive unclear guidance, and what parents intend to convey may not align with what adolescents perceive. Building on prior work showing that alcohol-specific communication is multidimensional and meaningfully linked to youth drinking outcomes, this study surveys parent–adolescent dyads (ages 15–18) to assess the content, frequency, and perception of substance-related conversations. The study also extends prior research by directly comparing parent and youth reports to identify alignment and discrepancies in communication. In addition, it addresses a major gap by characterizing marijuana-specific parental communication, which remains understudied despite increasing adolescent use. Finally, the study tests whether parents' trauma histories, particularly trauma involving substance use, shape how and what parents communicate to their children about alcohol and marijuana.

This study aims to better understand the experiences and perspectives of people with opioid use disorder (OUD) who have recently been hospitalized for a medical condition. Participants will complete a brief, confidential survey about their views on medications for opioid use disorder (MOUD), including barriers to starting treatment, factors that support treatment decisions, and what information they find most helpful. Individuals who meet eligibility criteria will be invited to participate. The information collected will help identify what patients need and prefer when making decisions about MOUD during a hospital stay. Findings from this study will guide the design of a future intervention that reflects patient identified needs and priorities.

LiveWell mBC is a group-based skills training program for women with metastatic breast cancer (mBC). The program teaches skills from dialectical behavioral therapy, an evidence-based psychotherapy, that have been adapted specifically to help women live as well as possible, with metastatic breast cancer. LiveWell mBC involves meeting with a small group of women with mBC plus two skills trainers 9 times total via telemedicine. Meetings include orientation plus 8 sessions learning and practicing skills including mindfulness, emotion regulation, distress tolerance and interpersonal effectiveness and they last 90 minutes each. We are interested in seeing whether the program can help women to balance their emotions and better manage distress (e.g., anxiety, sadness) and symptoms (e.g., fatigue, breathlessness, pain) that can be common when living with mBC.

Participants will be randomly assigned to one of two groups. They will have a 2 in 3 chance of being assigned to LiveWell mBC (experimental group) and a 1 in 3 chance of being assigned to Usual Care (control group). Women in the usual care group will continue to receive their standard oncology care. Participants in both groups will complete questionnaires four times total. Participants may be invited to participate in an exit interview about their experience. Participants will be compensated for completing questionnaires and the interview. For most people, participation will last approximately 4 months.

This research study aims to better understand how the brain and body change during physical or occupational therapy after a neurologic injury or condition. Adults who are already receiving outpatient neurorehabilitation will be invited to participate while they complete their regular therapy sessions. During therapy, participants will wear a lightweight cap that measures brain activity and will be video recorded so researchers can analyze movement patterns using computer software. These recordings do not change therapy activities and are for research purposes only. The study does not involve new treatments, medications, or procedures beyond standard care. Information collected may help researchers understand why recovery differs between individuals and improve future rehabilitation approaches.

We are recruiting healthy volunteers, age 18-65, for a 4-visit study designed to test whether brief non-invasive brain stimulation, called transcranial focused ultrasound (tFUS), changes how adults process pictures and odors. In addition to 3 tFUS sessions, the study procedures also include one 30-minute magnetic resonance imaging (MRI) session and four 1-hour encephalography (EEG) sessions during which we will measure brain structure and function. Each of the 4 visits last about 2-3 hours and should occur over a 2-4-week time period. Compensation is available to those that qualify.

This study will examine sex differences in the effects of cannabis in people that regularly use it. Men and women that use cannabis at least 4 days a week will participate in a study involving 1-3 in-person visits. The first visit will be used to determine eligibility for the study and will include a blood draw for genetic testing. Most participants will only complete the first visit. Participants that are eligible for the second part of the study will complete two additional visits. These two visits will last 7 hours each and take place at least two days apart. Visits include administration of either THC, the chemical responsible for many of the psychoactive effects of cannabis, or a placebo; completion of questionnaires; repeated blood draws; and a 1-hour brain scan.

The purpose of this study is to measure the efficacy and safety of KP-001 compared to placebo in patients with common venous malformations (VM), common lymphatic malformations (LM), or KTS/CLOVES syndrome. This phase 3, double-blind, randomized, placebo-controlled, parallel-group study will take place at multiple sites across North America. Vascular malformations like VM, LM, and KTS/CLOVES syndrome are serious, rare diseases with significant unmet medical needs. The study includes a 24-week double-blind treatment period with either KP-001 or placebo, followed by an open-label phase where all patients receive KP-001 up to Week 52. Patients weighing 40 kg or more will receive 100 mg of KP-001 once daily after breakfast, while those weighing less than 40 kg will receive a reduced dose based on their body weight.

This research study is being conducted at the Medical University of South Carolina (MUSC). The purpose of this study is to better understand injury to the small nerves that run between the ribs following rib fractures, and to learn what normal sensation and muscle appearance of the abdominal wall (muscles of the stomach area) look like in healthy adults. This information will help doctors better recognize and diagnose nerve injuries in patients who have had trauma, surgery, or other conditions affecting the abdominal wall.

Researchers will use simple sensory testing of the skin of the abdomen and ultrasound imaging to measure abdominal muscle structure. The sensory testing, called two-point discrimination, measures how well participants can tell the difference between two nearby points touching the skin using a small measuring tool that lightly touches the skin of the abdomen. Ultrasound imaging uses sound waves to create images of the inside of the body and will be used to measure the thickness and appearance of the abdominal muscles. This study includes two groups of participants: healthy volunteers and individuals with rib fractures.

Healthy volunteers will complete a single study visit lasting about 45 minutes, during which participants will undergo sensory testing, ultrasound imaging, and a short questionnaire. Participants with rib fractures will complete research procedures during their scheduled clinical follow-up visits, which include a baseline visit and three follow-up visits over approximately 12 weeks; research activities, including ultrasound imaging, will add about 30 minutes to each visit.

This will be a retrospective chart and imaging review of the patients who have undergone this procedure since its inception. From the patient charts, we will collect demographic and surgical information. From their imaging, we will collect pre- and postoperative radiographic measures to assess whether adequate distalization has been achieved. Patients that have received this surgery and are willing to provide patient reported outcomes will be contacted and asked about post-operative pain, functionality, and satisfaction.
