All Clinical Trials

The goal of this observational study is to learn how the brain's information processing changes during and following administration of serotonergic psychedelics (psilocybin, N,N-Dimethyltryptamine/DMT, Lystergic Acid Diethylamide/LSD, etc.) for people with and without mental illness receiving serotonergic psychedelics through any clinical trial at Yale University. The main questions it aims to answer are: 1. Do serotonergic psychedelics cause the brain to rely on new information more than previously learned information while under the influence? What about 1 day, 5-14 days, and 4-6 weeks after use? 2. Do serotonergic psychedelics cause long-lasting side-effects in how people perceive (see, hear, feel, etc.) the world and how easily people change their beliefs? 3. How does the brain's electrical activity change after using serotonergic psychedelics? How does the balance between excitation and inhibition change while under their effect? 4. Can changes in how the brain uses information predict who will benefit from a psychedelic and who will have side effects from psychedelics? Researchers will compare with people given placebos to see what changes in brain processing are unique to serotonergic psychedelics. Participants will have the opportunity to do some combination of the following: 1. Online computer assessments consisting of games and questionnaires that probe how participants think. 2. Magnetoencephalography (MEG) or electroencephalography (EEG) with eyes closed and with repeated clicks, images, or sensations delivered. 3. A magnetic resonance imaging (MRI) scan. 4. Semi-structured qualitative interviews about their experience after taking a serotonergic psychedelic recorded via Zoom. Read Less

The purpose of this study is to test whether a special memory training program, called CogMed, can help people with early memory problems. The Investigators want to see if this training improves memory and also helps reduce stress. The Investigators also want to see if CogMed results in changes to a blood biomarker called p-Tau 217, which possibly indicate Alzheimer's disease (AD). Read Less

This phase II trial studies how well 68Ga-PSMA PET/MRI or PET/CT works in early detection of liver cancer. 68Gallium-PSMA is a radioactive tracer designed to circulate through the body and attach itself to the prostate- specific membrane antigen (PSMA) protein on liver cancer cells. Magnetic resonance imaging (MRI) is a scan that uses magnetic and radio waves to produce detailed structural information of the organs, tissues, and structures within the body. Positron emission tomography (PET) is an imaging test that helps to measure the information about functions of tissues and organs within the body. A PET scan uses a radioactive drug (tracer) to show this activity. Computed tomography (CT) scan uses X-rays to create images of the bones and internal organs within your body. Combining a PET scan with an MRI or CT scan may help make the images easier to interpret. This trial may help determine if 68Ga- PSMA PET/MRI or PET/CT can improve upon the diagnosis and management of liver cancer in the future. Read Less

Hypothesis: More than 80% of the participants (n=40) will complete the intervention at three month (intervention completion) and the six month follow-up (retention rate as feasibility). More than 70% of the participants will report high overall study satisfaction (acceptability) with the intervention and study. This pre-pilot will inform intervention and procedural refinements for the pilot. Hypothesis: Participants who receive the intervention (n=57) will report more skin cancer-related preventive behaviors (e.g., mean of summed score of sun protection behaviors such as use of sunscreen, etc.) at three month and six month follow-up compared to those in the control condition (n=57, who will receive general information about physical activity and nutrition).

The goal of this clinical trial is to test the effects of dietary composition on the rhythms of food intake, appetite regulation, and rhythms of energy expenditure. Participants will: complete 2 field-based dietary interventions be provided with standard meals record daily food intake in a real-time manner complete 2 inpatient stays be provided with standard meals have frequent blood draws provide urine, saliva, and stool samples Read Less

This study seeks to answer the fundamental questions of which initial, first-line weight loss intervention should be offered to older adults with obesity and multiple chronic conditions and how to address the high non-response rates observed with most conventional strategies. A sequential, multiple assignment, randomized trial (SMART) design will permit the evaluation of treatment combinations that maximize weight loss and will provide data on constructing a future tailored, adaptive intervention. If successful, these findings will identify interventions that could markedly improve health and quality of life of these older adults, reduce long-term disability, and lower healthcare costs Read Less

Primary objective: To determine whether pregnancy increases the risk of recurrent CeAD and delayed stroke in women with prior CeAD based on long-term data. Methods: Multicentric, observational case-control study based on pooled individual patient data from several stroke centers. Primary endpoint: Primary composite outcome measure includes the following outcomes: (i) occurrence of recurrent CeAD, (ii) occurrence of ischemic or hemorrhagic stroke, (iii) death. Read Less

This is a study to confirm the clinical efficacy and safety of sonelokimab compared with placebo in the treatment of adults with active psoriatic arthritis who have had a previous inadequate response or intolerance to anti-tumor necrosis factor (TNF)α therapy. Read Less

The goal of this clinical trial study is to evaluate the impact of a personalized lifestyle intervention on improving healthspan. The primary questions of interest are whether the personalized intervention will result in improvements in muscle function, immune function, and cognitive function in adults aged 50-85 years. Participants will complete baseline assessments, receive an individualized intervention plan for approximately 3 months, and then complete post-intervention assessments. The intervention includes an exercise plan, nutrition recommendations, and general lifestyle goals that will be personalized to each participant. Read Less

This pilot study will include grade IV glioma patients treated with SSRIs during approximately a 17 week study period. Changes in cognition and evaluation of psychosocial factors from baseline to after 17 weeks of treatment with SSRI study drug will be calculated. Read Less

This study plans to learn if creative arts programs that include visual, musical, written, or physical expression can reduce symptoms of burnout syndrome, Post Traumatic Stress Disorder (PTSD), depression, and anxiety in critical care healthcare professionals. This study also explores if creative arts can enhance the connection to the purpose of work, the development of adequate coping skills, while providing time to connect with peers. Read Less
