The Sponsor of this research study is trying to develop a new experimental diagnostic blood test that may help detect colorectal cancer and other diseases. A diagnostic test identifies a specific disease or condition. Experimental means the test has not received approval by the United States Food and Drug Administration (FDA) for sale.
The main goal of this research study is to collect health information and blood samples from people who are going to have a standard-of-care screening colonoscopy. The blood samples along with other health information from patients who take part in the study may help the Sponsor develop new diagnostic tests that may help detect cancer or other diseases in other patients in the future.
This study will collect prospective data on clinical indications, outcomes, and adverse events related to Prostatic Artery Embolization (PAE) at the Medical University of South Carolina. Patients undergoing surgical treatment for benign prostatic obstruction causing LUTS will also be allowed to enroll in this registry for the purposes of comparison. Patients will be followed at 1, 3, and 12 months post-procedure, for a period of up to 5 years. Patients will remain enrolled in the registry for a period of 5 years.
This study will examine the behaviors and brains of adults between the ages of 60 and 80. Our goal is to better understand changes associated with the aging process. This includes potential changes in behavior/cognition as well as potential biomarkers for these changes (i.e. biological data like DNA, brain scans or brain activity that are related to these changes). Participants in the study will complete a number of tests that measure their cognitive, language, and sensory abilities. We will collect information about their brains using magnetic resonance imaging (MRI) and electroencephalography (EEG) and we will collect information about their genes using DNA extracted from blood samples. We will examine and compare the relationship between brain and behavior at 2 time points for the same 200 individuals. All data collected in this study will be stored in the Aging Brain Cohort repository study.
Hand disability after stroke has a profound negative impact on functional ability and independence. Hand therapy may be augmented with sensory stimulation for better outcomes. We have developed a novel sensory stimulation - unfelt vibration applied via a wristwatch. In this study, we will determine if combining this stimulation with hand task practice is superior to hand task practice alone.
The objective is to determine if continuous use of TheraBracelet in the home has a clinically meaningful effect in chronic stroke survivors. The study design is a double-blinded randomized controlled trial. We will enroll 40 chronic stroke survivors with moderate hand impairment. Subjects will be randomly assigned to the treatment or control group (n=20 per group). All subjects will wear the TheraBracelet device on the paretic wrist for 8 hours/day every day during their normal daily activity for 1 month. The device will deliver vibration (treatment) or no vibration (control). Double-blinding is possible because the treatment vibration is imperceptible (i.e., subthreshold). Measures of neural plasticity, the amount of the paretic arm use in daily living, clinical hand function, biomechanical grip control, and self-reported abilities for activities of daily living will be assessed at baseline, once a week during the month of wearing the device, and for 3-month follow-up, allowing determination of the efficacy and persistence.
Candidates for this study may or may not report disturbances in odor perception as their primary reason for seeking treatment at MUSC. This study is designed to collect long term, observational data from patients who are being treated with routine clinical care in health clinics at MUSC. Data from clinical questionnaires will be de-identified and stored in a database.
The purpose of the study is to generate a bio bank of specimens for research. We will tissue that would otherwise be discarded from clinical or surgical procedure and information from medical records. We will also collect discarded blood, urines and sputum. Collecting samples will help to better understanding the mechanisms of cardiovascular diseases, identify biomarkers for early diagnosis and to predict safety and efficacy of new therapies.
Traumatic Brain Injury is a risk factor for Alzheimer's Disease and other dementias. This study will use neuroimaging in Veterans and civilians with a history of TBI or without TBI to understand whether some of the brain changes that occur in Alzheimer's Disease are present in people with a history of TBI. The study is recruiting male and female military Veterans or civilians with or without TBI between the ages of 30 and 65.
The purpose of this study is to use neuroimaging to understand how networks in the brain change over time. Although the single most significant risk factor for developing Alzheimer's disease (AD) is age, the neurobiological processes underlying the transition from normal aging to AD are not well understood. Our group of researchers has developed ways to use MRI to detect small changes in certain parts of the brain. We will use neuroimaging to understand how the connections in the brain change over time in healthy aging. The goal is to discover which brain changes are present in healthy aging so that future studies can assess the risk for developing Alzheimer's Disease.
Participants will have two study visits (about 2 years apart) where they will undergo tests to assess mental function, fill out questionnaires, and undergo a blood draw, brain MRI and PET scan. At the second visit, participants will not repeat the blood draw and a PET scan.
Participants are required to have a Co-Participant accompany them for the first portion of each visit. This individual must be a reliable informant that has contact with the participant at least once per week.
Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.
