NCT04058132
The study includes people who have recently had a traumatic brain injury (TBI) and healthy controls who have not had a TBI and is designed to measure brain blood flow serially after a TBI. Studies have shown that small blood vessels in the brain may be injured during a TBI. The goal is to learn about brain blood vessel function from as early as the first week to 6 months after a TBI . The study uses Near Infrared Spectroscopy (NIRS) which uses small lights that detect oxygen levels in the blood, measuring blood flow in the brain. This is compared with magnetic resonance imaging (MRI). When blood flow increases in the brain in response to a stimulus, this is called cerebral vascular reactivity (CVR). The study aims to learn about CVR using a few minutes of special breathing similar to breath holding while in an MRI (magnetic resonance imaging), and CVR measures after one dose of a common drug called sildenafil (generic Viagra) 50 mg taken once during CVR measurements at each of up to 4 visits. The investigators will measure CVR at different times during a 6-month period in participants who have had a TBI to see how CVR measures and blood vessels function during the first 6 months after a brain injury.
NCT01793519
Background: * Rheumatoid arthritis (RA) is often treated with drugs known as tumor necrosis factor (TNF) inhibitors, that can help decrease joint pain and swelling and can even result in RA remission. However, TNF inhibitors may increase risk of serious infections or some types of cancer. * It is not clear if people whose RA has been in remission for a long time need to stay on the TNF inhibitor to remain in remission. If they can stop taking the TNF inhibitor without having their symptoms come back, they will be spared the side effects of these medicines. Some studies have shown that people can stay in remission after stopping a TNF inhibitor, but other studies have not confirmed it. Researchers want to see if people with RA in remission on a TNF inhibitor can stay in remission without this medicine. Also there may be a clinical, imaging (MRI, ultrasound), laboratory profile that will help to determine which patients remain in remission after stopping these drugs. Objectives: * To see whether RA remission can continue after discontinuing use of a TNF inhibitor. * To determine if clinical, imaging and immunological measurements can predict which participants will flare and which will remain in remission after discontinuing TNF inhibitor. Eligibility: -Individuals at least 18 years of age who have RA that is being controlled with TNF inhibitors. We plan to randomize 291 patients. Design: * The study has seven visits over about 2 years. Six visits occur in the first year of the study, about 12 weeks apart. The final study visit is 1 year after the end of the treatment phase. * At the first visit, participants will be screened with a physical exam and medical history. They will complete a questionnaire about their RA symptoms. A blood sample will be collected. They will continue to take their RA medicines during this time. * The second visit will repeat tests from the first visit. These tests will confirm that the RA is in remission. Imaging studies will be performed on the hands, wrists, feet, and their connected joints. After this visit, participants will stop taking their TNF inhibitors and will start to have injections of a study drug. This drug will be either the participant's original TNF inhibitor or a placebo. * There will be follow-up visits at weeks 12, 24, and 36. Participants will have a medical history and joint exam. They will also provide blood samples and answer questions about their RA symptoms. * At the sixth visit (week 48), participants will repeat the tests and imaging studies from the second visit. They will stop taking the study injections. * Continued RA treatment after this visit will be decided by the participant and his or her rheumatologist. Participants may take any recommended medicine, including the TNF inhibitor they had been taking before the study. They will also receive a questionnaire to complete at home and mail back before the final study visit. * At the final visit (week 100), participants will repeat the tests and imaging studies from the second and sixth visits.

NCT03396822
Multiple Sclerosis (MS) is an autoimmune disorder of the central nervous system. In MS, inflammation is known to attack areas of the brain, spinal cord, and optic nerves; resulting in disability. Current MRI technology provides an adequate view of the impact of MS on the "white matter" of the brain, which contains many of the connections between neurons. Quantification of lesions in the white matter due to MS are a standard part of clinical trials and clinical care in MS. However, it has long been known that MS not only can affect the white matter, but also the "gray matter," which contains the majority of the nerve cells in the brain and can cause inflammation in the meninges (the protective tissue that surrounds the brain and spinal cord). Autopsy studies have shown that the inflammation seen in the meninges is driven by a B-cells, a subset of white blood cells and that meningeal inflammation may be responsible for damage to the gray matter of the brain. Ocrelizumab is a new treatment for multiple sclerosis. This medication works by targeting and destroying circulating B-cells. It is thought that this may reduce the level of meningeal inflammation in patients with multiple sclerosis. By reducing meningeal inflammation, this medication may result in less damage to the gray matter and subsequently less disability in MS patients. In this study, the investigators will evaluate the use of a method on 7 tesla (7T) MRI to identify inflammation in the meninges as a potential predictor of response to ocrelizumab treatment for multiple sclerosis. Further, the investigators will evaluate if this MRI technique can be used to monitor the long-term effect of the medication on meningeal inflammation and the development of damage to the gray matter of the brain.
NCT03291847
The purpose of this mechanistic study is to evaluate the effects that maternal buprenorphine-naloxone maintenance have on the neurobehavioral development of the fetus and infant. To accomplish this, the investigators will study a sample of 120 opioid dependent pregnant women that will receive buprenorphine-naloxone as part of substance abuse treatment at a comprehensive care treatment facility for pregnant and parenting women with substance use disorders. Fetal neurobehavior and maternal physiology will be assessed, via an established maternal-fetal data acquisition system, at 4 points during gestation: 24, 28, 32 and 36 weeks. Infant birth parameters and Neonatal Abstinence Syndrome (NAS) spectrum display will be evaluated at birth, and infant neurodevelopment will be assessed during the first month of life.

NCT00319579
Kidney transplantation, a 'miracle' of modern medicine, is the preferred treatment option for End Stage Renal Disease compared to dialysis, patients who receive kidneys have a 70% reduction in risk of death, a dramatically improved quality of life and cost the health care system considerably less. As a result there are over 3000 Canadians, and 57,000 Americans on the waiting list for a kidney. To meet the shortage in cadaveric kidneys, rates of living kidney donation have nearly doubled over the last 10 years, and will continue to rise with growing demand. Yet despite its advantages for the recipient, living kidney donation remains a complex ethical, moral and medical issue. The premise for accepting living donors is that the "minimal" risk of short and long-term medical harm realized by the donor is outweighed by the definite advantages to the recipient and potential psychosocial benefits of the altruistic gift to the donor. The only benefit for the living donor is psychological - donors experience increased self-esteem, feelings of well-being and improved health related quality of life with their altruistic act of assuming medical risk to help another. The short-term consequences of living donation are well established. On the other hand the long-term implications of living kidney donation are far less certain. This study will look at the long term implications of living kidney donation.
