This project aims to identify and evaluate internal barriers that inhibit engagement with pharmacological treatment for opioid use disorder (OUD). Participants, consisting of adults diagnosed with OUD, will complete a series of surveys that will take approximately 30 minutes. In conducting this study, investigators intend to identify barriers that could be improved by future interventions.
This study will examine sex differences in how the brain processes reward in people that regularly use cannabis. Men and women that use cannabis at least 4 days a week will participate in a study involving 3 in-person visits. The first visit will be used to determine eligibility for the study. The other 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; and a 1.5-hour brain scan.
The goal of the current project is to gather preliminary data from adults across the United States using an online survey study regarding alternative cannabinoid use, motivations, and experiences. We will also conduct interviews with some participants to gather more open-ended responses regarding the targets of interest in order to inform future work about alternative cannabinoids.
Ritlecitinib has been approved for treating severe alopecia areata (AA) in adults and adolescents aged 12 and older in the US, EU, and other countries, based on a positive benefit/risk assessment. However, there are no approved treatments for AA in children aged 6 to under 12. Study B7981027 is being conducted to evaluate the efficacy and safety of ritlecitinib in this younger group. This study is part of the EU Pediatric Investigation Plan (PIP) and fulfills a post-marketing requirement in the US.
The purpose of this research study is to assess if the study drug SION-719 is safe and well-tolerated in people with cystic fibrosis who are already taking Trikafta, understand the effect of SION-719 on the body by measuring chloride levels, and to learn how the body absorbs, distributes, and gets rid of the study drug in people with cystic fibrosis. This study is a placebo controlled cross-over study with two study treatment periods, and participants will take part in both study treatment periods. Participants will be assigned either study drug or placebo. Participants will remain on standard dose of physician-prescribed Trikafta throughout the study. This study will be approximately 16 weeks, or 112 days long.
This study is enrolling two different groups of individuals. The first group are those individuals referred for right heart catheterization (RHC), which is a procedure performed to check heart pressure taken inside the heart. The second group of individuals are those who have tricuspid regurgitation (TR) (blood that leaks due to improper valve closure) and are undergoing tricuspid valve intervention to correct the regurgitation. The RHC group will be referred to as the control group and the tricuspid intervention group will be the treatment group in this study. This study involves collecting existing medical records on both groups, as well as an arterial (from an artery) blood sample and venous (from a vein) blood sample from the vein that carries blood away from the liver. The control group will not involve any additional procedures or follow up. The TR population will perform a 6 minute hall walk test before their tricuspid valve intervention and again during the six month post procedure follow up. The TR group will also have repeat arterial and venous blood collection at the six month follow up. The TR group will have data collected for up to two years post tricuspid valve intervention.
This study is for adult men with previously untreated prostate cancer. The purpose of this study is to evaluate the safety and effectiveness of the combination of two emerging treatment techniques (hypofractionated radiotherapy with microboost technique). Participation will include standard of care visits along with questionnaires and blood draws completed for research purposes. There is optional banking of blood and prostate biopsy tissue which will not require extra biopsies. Participation in this study is anticipated to last approximately 6 weeks with follow up every three months for two years then twice yearly for years 3-5.
This study is recruiting non-metastatic breast cancer survivors who were diagnosed between ages 18 and 51 and are currently 6 months to 5 years post-treatment. Eligible participants must have a score of 5–14 on the PHQ-8 depression screening tool. This study is testing a digital mindfulness meditation-based program. "Investigational" means it has not been approved by the United States Food and Drug Administration (FDA). Participants will be randomly assigned (like drawing one number out of three at random) to one of three groups: (1) live online mindfulness classes over Zoom, (2) a specially designed mindfulness app, or (3) guided audio meditations. The primary purpose of this study is to determine if different ways of delivering digital mindfulness training can improve mental health and well-being in younger breast cancer survivors. The program is delivered either by live online sessions, through a mobile app, or by listening to guided meditation recordings. Participants can expect to be in this study for about 9 months, including a 6-week training program and questionnaires before, during, and after training. Participants will be enrolled for a duration of 9 months, and a total of 15 patients will be recruited locally over the course of 36 months.
We wish to examine human liver to determine whether and to what extent paxillin is expressed (using immunohistochemistry). Existing liver specimens will be identified by ICD-10 search to identify patients with MASLD who have undergone liver biopsy within the last 5 years.
This cross-sectional study aims to examine the impact of visual cues on listeners' perception of speaker age. Eligible speaking participants include adult males and females between the ages of 18–90 years old without voice or hearing disorders. Eligibility will be determined by research coordinators via patient demographic forms and validated voice and hearing assessments. Speaking participants will have two audio recordings taken: (1) sustained vowel sound and (2) reading of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), a standardized tool employed to evaluate the perceptual characteristics of voice quality across a wide age range. To develop the materials for the listening participants, CAPE-V audio recordings obtained from the speaking participants will be systematically paired with race and age-matched photographs obtained from a publicly available database. The finalized materials will encompass three experimental conditions: (1) audio only, (2) audio presented with a standardized photograph of an individual matched to the speaker's gender and age, and (3) audio presented with a standardized photograph of an individual matched for gender but differing in age. Naïve listening participants, blinded to the experimental conditions, will then be presented with these materials in a randomized order and asked to estimate the perceived ages of the speakers. Additionally, basic acoustic analyses of each sustained vowel sound recording (e.g., jitter, shimmer) will be conducted by a trained professional using the speech analysis software PRAAT.
