Synucleinopathies are a group of rare diseases associated with worsening neurological deficits and the abnormal accumulation of the protein α-synuclein in the nervous system. Onset is usually in late adulthood at age 50 or older. Usually, synucleinopathies present clinically with slowness of movement, coordination difficulties or mild cognitive impairment. Development of these features indicates that abnormal alpha-synuclein deposits have destroyed key areas of the brain involved in the control of movement or cognition. Patients with synucleinopathies and signs of CNS-deficits are frequently diagnosed with Parkinson disease (PD), dementia with Lewy bodies (DLB) or multiple system atrophy (MSA). However, accumulation of alpha-synuclein and death of nerve cells can also begin outside the brain in the autonomic nerves. In such cases, syncucleinopathies present first with symptoms of autonomic impairment (unexplained constipation, urinary difficulties, and sexual dysfunction). In rare cases, hypotension on standing (a disorder known as orthostatic hypotension) may be the only clinical finding. This "pre-motor" autonomic stage suggests that the disease process may not yet have spread to the brain. After a variable period of time, but usually within 5-years, most patients with abnormally low blood pressure on standing develop cognitive or motor abnormalities. This stepwise evolution indicates that the disease spreads from the body to the brain. Another indication of this spread is that acting out dreams (i.e., REM sleep behavior disorder, RBD) a problem that occurs when the lower part of the brain is affected, may also be the first noticeable sign of Parkinson disease. The purpose of this study is to document the clinical features and biological markers of patients with synucleinopathies and better understand how these disorders evolve over time. The study will involve following patients diagnosed with a synucleinopathy (PD/DLB and MSA) and those believed to be in the "pre-motor" stage (with isolated autonomic impairment and/or RBD). Through a careful series of follow-up visits to participating Centers, we will focus on finding biological clues that predict which patients will develop motor/cognitive problems and which ones have the resilience to keep the disease at bay preventing spread to the brain. We will also define the natural history of MSA - the most aggressive of the synucleinopathies. Read Less

The purpose of this study is to improve behavior control displayed by persons with traumatic brain injury by assessing effectiveness of treatments for post-TBI irritability and aggression. Read Less

The purpose of this research study is to demonstrate the safety and efficacy of using two CRS Arrays (microelectrodes) for long-term recording of brain motor cortex activity and microstimulation of brain sensory cortex. Read Less

The purpose of this study is to learn about the experience of women with vasculitis who become pregnant. In particular, the study will consist of several online surveys to assess 1. each woman's vasculitis severity and pregnancy-related experiences, and 2. pregnancy outcomes. Read Less

This is a single center, open-label, phase II study of venetoclax (ABT-199) added to ibrutinib or acalabrutinib in patients with high-risk CLL who have received at least 12 months of ibrutinib or acalabrutinib monotherapy. The study will estimate the therapeutic efficacy of venetoclax consolidation in patients who have detectable CLL after receiving ibrutinib or acalabrutinib for at least 12 months and who have high risk CLL.

This pilot trial studies the impact of genetic information on developing liver damage caused by asparaginase in participants with newly diagnosed acute lymphoblastic leukemia. Testing saliva samples may help doctors find certain genetic markers that may predict whether participants will tolerate asparaginase, which is given as part of clinical care for acute lymphoblastic leukemia.

Given the severe consequences of alcohol relapse following liver transplantation for alcoholic hepatitis (AH-LT), it is critical to accurately identify alcohol use and implement alcohol interventions early in the post-transplant period to optimize patient outcomes. The proposed randomized clinical trial will examine the implementation and effects of integrated, person- and computer-delivered alcohol treatment compared to standard care on alcohol use (assessed by self-report and biomarker), mood, quality of life and survival following AH-LT. Predictors of 12-month post-transplant alcohol outcomes will be explored to allow future improved tailoring and targeting of these treatments. Read Less

This research trial studies characterization of T-cell repertoire through next-generation sequencing in patients with acute myeloid leukemia undergoing stem cell transplant. Characterizing T-cell repertoire may help to understand if immune system plays a significant role in high risk patients with acute myeloid leukemia. Read Less

This phase I/II trial studies the side effects and how well cladribine, idarubicin, cytarabine, and quizartinib work in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndrome that is newly diagnosed, has come back (relapsed), or does not respond to treatment (refractory). Drugs used in chemotherapy, such as cladribine, idarubicin, and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving quizartinib with cladribine, idarubicin, and cytarabine may help to control acute myeloid leukemia or high-risk myelodysplastic syndrome. Read Less

This study will examine how various FDA-approved seasonal influenza vaccine types, used in a manner consistent with their approved use, impact the characteristics of influenza specific antibodies in humans, and how these responses differ based on age and prior immunization history. Read Less

This is a randomized, active-controlled, parallel-group, double-blind Phase II trial, of oral restorative microbiota therapy (RMT) or placebo combined with intravenous (IV) durvalumab (MEDI4736) plus chemotherapy in patients with treatment naïve advanced or metastatic adenocarcinoma non-small cell lung cancer (NSCLC) Read Less

LIINC is a study of volunteers who were previously infected with SARS-CoV-2 (also known as novel coronavirus or COVID-19) who have recovered from acute infection. The study is designed to provide a specimen bank of samples with carefully characterized clinical data. LIINC specimens will be used to examine multiple questions involving the virologic, immunologic, and host factors involved in COVID-19, with a focus on understanding variability in the long-term immune response between individuals.
