People with mild cognitive impairment (MCI) are at increased risk of dementia, including Alzheimer's disease. Cognitive training may be a useful treatment strategy in MCI. The COGIT-2 study, which is funded by the National Institutes of Health, will compare the effects on cognition and function and brain MRI changes of high dose crosswords (4 puzzles…
This research is being done to better understand rejection in transplant recipients with HIV who receive kidneys from donors with HIV compared to donors without HIV. If you have any questions regarding this study, please contact the Transplant Clinical Research Center (TCRC).
The purpose of this study is to understand how liver disease affects thinking and memory, both before and after transplant. Participants will take a cognitive test, which will be a series of tasks and questions similar to a video game, at home on their own computers, tablets, or phones. This will take approximately 45 minutes, and participants will do this…
Early Age-Related Hearing Loss Investigation (EARHLI) is a study to obtain information on how a hearing aid-based intervention can prevent cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD). Age-related hearing loss (ARHL) is the third most common chronic condition in older adults. The…
A complication that can occur after liver transplant (LT) is rejection, in which the patient's immune system damages the transplanted liver. This complication can be prevented with immunosuppressant medications, which are routinely used after LT. The main purpose of this study is to determine if bacteria in the intestine (gut microbiome) may affect the…
The purpose of this observational research study is to identify things that contribute to outcomes in patients with alcohol-associated liver disease who are being considered for liver transplant and who have less than 6 months of sobriety. We will look at many things including images of the liver and heart, blood tests, urine tests, stool tests and liver…
We are looking for participants for a study on the role of immune response in Parkinsons disease (PD) and Alzheimer's disease (AD). We are inviting people WITH PD, WITH AD, WITH amnestic Mild Cognitive Impairment or WITHOUT PD or AD to come and participate. We will be doing several questionnaires, a motor exam, and a short cognitive assessment, in…
The main purpose of this study is to deeply characterize cognitive function in liver transplant recipients, differentiate among different causes of cognitive impairment, and identify contributors to cognitive impairment. Participants will receive a comprehensive neurological exam, cognitive assessment, neuropsychological testing, MRI of the brain, and blood…
The purpose of this study is to evaluate the safety of siplizumab when used as induction immunosuppression in patients with primary sclerosing cholangitis or autoimmune hepatitis undergoing liver transplantation. Induction immunosuppression drugs are very potent anti-rejection drugs that are given immediately after transplantation to prevent rejection.…
The purpose of this study is to learn more about the effects of functional status (also known as "frailty") using a physical test in patients with liver disease on their health outcomes. We are enrolling patients prior to liver transplantation, and will continue to assess their functional status post transplant. If you have any questions regarding…
The purpose of this study is to determine how inflammation is related to changes in the brain that occur during the progression of Alzheimer's disease. If you are eligible for this study, we will ask you to complete 3-4 study visits over the course of about 5 months. Participation includes memory testing, a blood draw, MRI, PET scans, and a lumbar…
The goal of this study is to focus on the genetic influences on Alzheimer's disease (AD) risk. We are looking for families and/or individuals (affected or unaffected) of any ethnic background with a family history of Alzheimer's disease and willing to participate.
The purpose of this sponsor initiated multi center registry is to collect additional data on the performance of the FDA Approved OCS Liver System and post transplant clinical outcomes for patients who are transplanted with an OCS Liver perfused donor liver in the real world setting. If you have any questions regarding this study, please contact the…
This study aims to find genes that cause Alzheimer's Disease in African Americans and Hispanics/Latinos. Participants are eligible if African American or Hispanic/Latino and 60 years of age or older. Study participation would entail completing a memory assessment, having their blood drawn, and a brief physical exam with a questionnaire. Compensation of…
