The purpose of this study is to test the performance of the wAID-P across 21 sites in the Parkinson Study Group. Each site will perform imaging, clinical scales, diagnosis, and will upload the data to the web-based software tool. The clinical diagnosis will be blinded to the diagnostic algorithm and the imaging diagnosis will be compared to the movement disorders trained neurologist diagnosis.

Individuals with type 1 diabetes often develop an impaired awareness of hypoglycemia (IAH), meaning they are not fully aware of having low blood glucose levels. This research study is looking to determine what happens in the brain after repeat episodes of hypoglycemia.

This study is evaluating the efficacy of MultiStem (drug) on functional outcome in participants with ischemic stroke.

CP is a progressive fibro-inflammatory disease where EPI develops due to destruction of pancreatic parenchyma or pancreatic duct distortion. EPI results in maldigestion, leading to fat-soluble vitamin deficiencies, weight loss, malnutrition, and impaired quality of life (Qol). Signs and symptoms of EPI include abdominal bloating and cramping, diarrhea, foul-smelling, greasy stools (steatorrhea), and unintentional weight loss. Pancreatic enzyme replacement therapy (PERT) is the mainstay of treatment of EPI. Treatment is aimed at reduction of maldigestion-related symptoms, and prevention of malnutrition and its related morbidity and mortality. CREON® is a PERT that has been FDA approved since 2009 for the treatment of EPI due to cystic fibrosis, CP, pancreatectomy, or other conditions

The purpose of this pilot research study is to test whether a tool called “High-Resolution Manometry” can diagnose laryngeal dystonia (also known as spasmodic dysphonia) and measure how well treatment works. High-Resolution Manometry measures pressures from a small catheter that is passed from your nose into your throat. We believe that pressures in the throat might be different for people with laryngeal dystonia than for people without laryngeal dystonia, or with other types of voice disorders. If we can diagnose laryngeal dystonia shortly after symptoms start, we can get patients the treatment they need sooner.

The purpose of CureGN2 is to gather a group of people with glomerular disease to create a source of information and blood and urine samples, so that researchers can easily and effectively study glomerular disease.

The purpose of this study is to critically assess the current treatment that patients are undergoing by reviewing routine data collected and adding one additional outcome questionnaire solely for research purposes

This is pilot study designed to test the hypothesis that maternal probiotic supplementation is associated with infant gut microbiome variation and improved neurodevelopmental outcomes as measured by ERP performance. The primary aim is to determine if maternal probiotic supplementation during pregnancy and lactation is associated with improved recognition memory performance in infants of diabetic mothers (IDMs). This will involve recruitment and enrollment of pregnant mothers who have been diagnosed with gestational diabetes and randomization to an intervention or control group. Women in the intervention group will receive a standardized probiotic supplement during the third trimester of pregnancy through the first month of lactation. We will compare the IDMs who are exposed to probiotics via maternal supplementation or not with respect to auditory and visual ERPs at 1 and 6 months of age to determine if probiotic supplementation is associated with improved hippocampus function in infancy. The secondary aim is to examine whether maternal probiotic supplementation during pregnancy and lactation is associated with differences in maternal milk and infant fecal microbiome signatures as well as maternal milk and infant serum inflammatory protein levels. Microbial analysis will be performed on infant stool and maternal breast milk samples at one and six months of age. Infant serum and maternal breast milk inflammatory protein levels will be measured at one and six months postpartum.

This is a study of individuals older than 18, undergoing abdominal procedures in which the liver is accessible, and are amenable to liver samples being collected during their surgical procedure, with the option to participate in a specialized scan that can provide information on liver health, stiffness, and fat content. This study is trying to figure out how senescent (aging) cells in the liver are related to an individual's health status and better understand the association between these cells and different metabolic diseases.

This is a double-blind randomized placebo-controlled clinical trial examining choline supplementation in 2-5 year old children with Fetal Alcohol Spectrum Disorders. Outcome measures are neurocognitive tests of memory, attention, and behavior.

This trial is an open label, randomized, stratified 2-arm Australian-led multicenter phase 3 clinical trial undertaken in two stages. Participants (age >= 11 years and <= 45 years) with intermediate and poor-risk metastatic germ cell tumors will be randomized into either a “standard BEP” group or “accelerated BEP” group. Participants will be assigned to the two treatment arms in a 1:1 ratio and evaluated weekly, and then for 5 years after completing the study to assess the long-term effects of the chemotherapy. Bleomycin, Etoposide, Cisplatin (BEP) administered 3-weekly x 4 remains standard 1st line chemotherapy for intermediate- and poor-risk metastatic germ cell tumours (GCTs). BEP is accelerated by cycling Cisplatin and etoposide 2-weekly instead of 3-weekly. The aim of this study is to determine if accelerated BEP is superior to standard BEP as first-line chemotherapy for intermediate and poor risk metastatic GCTs.

We are doing the RARE study to learn more about Cystic Fibrosis (CF). CF is caused by mutations in a gene that produces a protein called the cystic fibrosis transmembrane conductance regulator (CFTR). In people with CF, the CFTR does not function correctly. Medications are being developed to help the CFTR function better, but those medications mostly benefit people with common CFTR mutations. There are more than 1,900 mutations of the CF gene. Some of these mutations are rare and found only in a few people. The goal of this research study is to collect specimens (blood, nasal cells, rectal cells) from people with rare CFTR mutations. Another purpose of this study is to create induced pluripotent stem cells or iPS cells. “Pluripotent” stem cells are cells that can be changed into almost any cell type of the body (such as lung or intestine). They can be kept alive and stored indefinitely. There are different kinds of pluripotent stem cells. Inducted pluripotent stem cells can be created from many different kinds of specimens (such as blood, nasal cells, rectal cells). This is different from embryonic stem cells, which can only be derived from embryos. The specimens collected during this study and iPS cells created from them will be stored for use in future research to learn more about CF and study the effect of new medications. This could identify new medications that may help people with rare CFTR mutations.

The goal of the proposed project is to investigate whether brain abnormalities are present in children to young adults after the recovery from coronavirus disease 2019 (COVID-19).

To collect additional real-world safety and effectiveness data for the OCS™ Lung System and to expand the long-term clinical evidence supporting the use of OCS™Lung System in lung transplantation.

This study is enrolling participants who have been diagnosed with juvenile spondyloarthritis, are taking a tumor necrosis factor inhibitor (TNFi) and have reached a clinically inactive disease state for a minimum of six months. Researchers want to know if children who have maintained inactive disease for at least 6 months can maintain quiet disease without taking their medication as frequently or stop the TNFi therapy. Quiet disease means that disease related symptoms are not active or being experienced in the patient. Researchers also want to know the safest method to bring patients off medication. If a flare does occur during therapy reduction, researchers want to find out whether they can predict when a flare is most likely to happen, and how quickly an inactive disease state can be recaptured.

This study will evaluate if there is a relationship between bone health, fertility, and metabolism to help develop future treatments for SCI. Both men with and without SCI will be participating in this trial to better understand how bone health, fertility, and metabolism are impacted by an injury to the spinal cord.

This phase II trial studies how well combination chemotherapy works in treating patients (≤ 30 years old) with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed).This trial may help doctors find out what effects, good and/or bad, regimen UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT)and regimen ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).

The purpose of the current study is to test the effects of two forms of cognitive training: visual perception training or visual cognitive control training in individuals with early psychosis.

This research is being done to help us better understand the different DNA repair disorders. We will collect data and samples that we will use to develop new therapies and medicine to help treat the disease. We expect that participants will be in this research study for 3 years. Visits will occur every six months and alternate between in-person and remote. Remote visits should be expected to last 1-2 hours, and in-person visits should be expected to last 3-4 hours.

In the first phase of the study, participants will be asked to complete two sets of appointments six months apart. During both sets of appointments, participants will be asked to complete interviews and questionnaires about their life experiences and mental health, and they will have an EEG and fMRI while completing computerized tasks. The second phase of the study is optional. In this phase, participants will test one of two forms of computerized cognitive training, or brain games. They will be asked to complete 10 hours of training over a 3-6 week period. After the training period is over, they will have two sets of follow up visits, one right after the training period and one five months later. At these appointments, participants will complete the same activities done in the first phase of this study, including the interviews, questionnaires, and imaging (fMRI and EEG) combined with computerized tasks. We are recruiting two groups of participants for this study. One group will include individuals who experience hallucinations, delusions, paranoia, or a psychosis disorder (i.e., schizophrenia), and the other group will be individuals who do not have a diagnosis or family history of schizophrenia, bipolar disorder, or autism spectrum disorder.

We are trying to learn more about how the brain controls movement and how this affects function after stroke. We expect differences in the side of brain damage to result in distinct movements of each arm. We will collect information with standard clinical exams and movements during tasks completed on the Kinereach virtual reality system. We will compare results between people who have and have not had a stroke.

We are continuing to study the SARS-CoV-2 coronavirus and the evolving new variants. We are looking at drugs that have Food and Drug Administration (FDA) approval for other uses. The goal is to determine if these drugs can make participants who get the coronavirus feel better faster and reduce death and hospitalizations.

The purpose of this study is to measure levels of blood and brain chemicals related to oxidative stress and inflammation in healthy volunteers and individuals with Type 1 Gaucher disease (GD1) to see if these levels are altered by GD1. We will also examine if there is a change in these blood and brain chemicals after participants begin taking oral N-acetylcysteine (NAC), which is available both as a prescription medication and a natural product that has antioxidant and anti-inflammatory effects.

The researchers aim to prove that Qigong practice can result in reduced or relieved neuropathic pain, improved mood, life satisfaction, self-efficacy, enjoyment to move, and community integration; and decreased fear of movement, use of medication or health care services for adults with spinal cord injury.

Freezing of gait is a common problem in people with Parkinson's disease. Episodes of freezing can be overcome when a sensory cue is provided. This study will further develop and study the efficacy of a wireless shoe insole that can monitor walking and provide a cue (acoustic or vibrotactile) when a freezing event is detected. The experiment is designed to further test the ability of the device and algorithm to reliably detect freezing and release the episode with an external cue. This study has the potential to develop a tool that can help reduce the incidence and severity of freezing events in people with Parkinson's disease.

The purpose of this study is to determine what clinical, electrocardiogram, and cardiac magnetic resonance imaging factors identify patients at risk for developing rapid irregular heartbeats requiring therapy by implantable defibrillator. We expect that participation will last for up to 4 years. The procedures will include wearing a heart monitor (Holter) for 24 hours, obtaining a blood sample for markers of heart disease, and having a cardiac magnetic resonance examination with contrast – a substance given intravenously to make the images better, prior to defibrillator implant. After the initial visit, participation will not require any additional visits since information about the clinical course will be acquired from medical records.

This is a registry study. The Cardiac Sarcoidosis Consortium (CSC) is an international, multicenter partnership among physicians and allied professionals at major medical centers with the unifying purpose to learn more about cardiac sarcoidosis through collaborative research.

The objective of the study is to define quality of life in patients with upper airway stenosis after bypassing the stenosis with either tracheotomy or t-tube stenting. Participants complete surveys over 2 years to collect quality of life information.

Prospective study investigating brain activity associated with markers of suicidal behavior (SB) in adolescents.

Severe aortic valve stenosis can include stiffening and hardening of the heart valve leaflets (tissue that opens and closes in the heart valve) so that the valve cannot work properly. If left untreated, excessive strain put on the heart muscle will eventually cause it to fail or lead to other serious complications. This study is a research project to assess a way of replacing aortic valves without the need for open-heart surgery and without surgically opening the heart to remove the narrowed valve. The device under study is called the ACURATE Transfemoral Aortic Valve System. The study will compare the safety and effectiveness of the ACURATE Valve, along with other commercially available TAVR devices.
