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.

The long-term objective of this proposed R24 program is to enhance our understanding of how circadian rhythm disruption contributes to vulnerability to alcohol-induced organ damage, and to explore the underlying mechanisms (e.g. microbiota) that could lead to the identification of novel therapeutic targets. This knowledge aims to inform the development of innovative strategies to prevent and to treat alcohol-related pathologies.

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.

The purpose of the study is to evaluate the safety and how well the medication sotatercept works versus placebo in treating Heart Failure with a Preserved Ejection Fraction. The study will also look at information obtained from the tests performed as part of the study to see if subjects have improvement in symptoms of heart failure. Participation in this study will last approximately 26 months. During the study period subjects will be asked to attend regular study visits with the research coordinator. These visits will include such activities as blood tests, questionnaires, physical evaluation by a study doctor, a right heart catheterization with exercise, echocardiogram, and 6 minute hall walks. There will be 35 visits as part of participation in this clinical trial.

Participants will be randomized to either the treatment group (and receive the medication) or the control group (and not receive the medication). Subjects will have a 2:1 chance of receiving the study medication during their participation in the trial. The treatment assignment is determined by randomization, where a computer selects at random which treatment group you will be in (like drawing straws). Neither the subject, nor the blinded personnel will know which group subjects are in. Neither the subject nor the study doctor will decide what group subjects are assigned. Participants from the placebo group in CADENCE who enter HARMONIZE at Visit 9a will be randomized 1:1 to one of the active treatment groups. Participants from an active treatment group in CADENCE entering HARMONIZE after Visit 9a will be allocated to continue in the same treatment group (ie, sotatercept dose level) as in CADENCE.

The proposed research will qualitatively examine adolescent perspectives on adapting Written Exposure Therapy (WET), an evidence-based treatment for posttraumatic stress disorder (PTSD) among adults, for use with adolescents. The present study will take the first step in adapting WET for adolescents by conducting interviews with adolescents with PTSD. Interview questions will focus on identifying perceptions of WET and recommendations for adapting WET for the needs of adolescents. A brief survey will also be conducted. Participation in the interview and survey will involve a one-time study visit that lasts up to 60 minutes and can be conducted in person or virtually. Adolescent participants need be accompanied by a caregiver either in person or virtually.

An international research registry called the CorEvitas International Adolescent Atopic Dermatitis (AD) 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 atopic dermatitis.

This study is for patients that have been diagnosed with ovarian cancer who are taking bevacizumab. This study is testing two investigational drugs called nelfinavir and hydroxychloroquine. "Investigational" means it has not been approved by the United States Food and Drug Administration (FDA) for the treatment of cancer. The primary purpose of this study is to see if these two medications in combination with bevacizumab are safe and effective in ovarian cancer. These drugs will be given by mouth. Participants in this study can expect to be in this study for 6 months for data collection, but may continue on the study medications longer if seeing benefit.

The primary objective of this proposal is to conduct surveys and qualitative interviews to get feedback from (1) stakeholders and (2) people with lived experience of opioid use and a related medical hospitalization, on the barriers and facilitators of new potential strategy of treatment. The potential proposed intervention we will ask questions about is the direct mailing medications for opioid use disorder (OUD) in an attempt to overcome many of the barriers that interfere with treatment retention (i.e. transportation). Qualitative interviews will be used to get feedback on the feasibility, appropriateness, and acceptability of mailing maintenance medications for OUD after a hospital discharge. In a future study, this feedback will be used to develop a protocol to test this method.

The purpose of this study is to compare the usual treatment alone to the usual treatment plus nivolumab. This study seeks to find if this approach is better or worse than standard of care for colon cancer. Treatment and follow up for this study may be up to 3 years. The procedures include CT or MRI scans and chemotherapy. Risks include diarrhea, nausea, vomiting, hair loss, anemia, sores in mouth, and muscle weakness. You may or may not receive a direct benefit from participating in this trial, however, information learned from the trial may help other people in the future.

The objective of the study is to evaluate the safety and efficacy of the BrioVAD System by demonstrating non-inferiority to the HeartMate 3™ (HM3) LVAS (Abbott) when used for the treatment of advanced, refractory, left ventricular heart failure.
