The purpose of this study to learn more about Limb Girdle Muscular Dystrophy by measuring how muscles change over a twelve-month period. Our clinical evaluator will test muscle strength and participants will be asked to complete a series of questionnaires to find out how Limb Girdle impacts daily activities. This information will help plan future studies and drug development for people with LGMD.

REM sleep behavior disorder may predict the eventual symptom development of Parkinson’s disease, dementia with Lewy bodies, or multiple system atrophy. This occurs over years to decades and the sleep disorder may hide other typical symptoms and result in a delay in diagnosis. We are studying the changes in the brain over two years. We will do high field MRI’s (7T) and other tests of neurological function of people who have REM sleep disorder and people who don’t have this disorder (matched for age and sex).

The goal of this proposal is to develop fully automated, high performance, motion-corrected MRS sequences for the brain and spinal cord, that are also easy to share (no additional external hardware needed) with other institutions and easy to use.

This study is being sponsored by the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC). We want to learn more about improving the treatment and outcomes for patients who have a diagnosis of a single ventricle, such as Hypoplastic Left Heart Syndrome (HLHS) or similar heart defects.

This phase I/II trial evaluates the highest safe dose, side effects, and possible benefits of tegavivint in treating children, adolescents, and young adults with recurrent or refractory solid tumors, including lymphomas and desmoid tumors.

This is a study enrolling patients receiving care for early psychosis across the United States. Participants will be randomly assigned to one of two groups. The first group will use two mobile apps, computerized brain training and a motivational smart phone app, for a period of 12 weeks. The other group will participate in their regular clinical care. There will be 4 study timepoints: intake, post-training, 6-month follow up, and 12-month follow up. There is also an optional interview about experiences of loneliness.

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.

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).

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.

Risk for suicidal behavior in young people may include particular types of brain functions. The goal of this research is to learn more about the biology of the brain as it relates to suicidal thoughts and behaviors.

The purpose of this study is to examine a new, experimental treatment for adolescents at risk for suicide attempts called neurofeedback training. In neurofeedback training, you are trying to control your brain function on purpose. In this study, your child will see their brain activity (displayed like a thermometer). He/she will recall positive memories to try to change the levels of their brain activity shown on the visual thermometer inside a scanner.

This study is being conducted to determine when is the best time to do surgery is and when to start rehabilitation after surgery for the treatment of a multiple ligament knee injury. The study will randomize (i.e. a coin toss) when you have surgery and when you begin rehabilitation (early or delayed surgery and early or delayed rehabilitation). The type of surgery is decided between you and your surgeon. Rehabilitation is tailored to the type of surgery you have. You will fill out some questionnaires and have your knee examined at your normal postsurgery appointments with your surgeon.

The effect of enzyme replacement therapy on how well your kidneys are responding to enzyme replacement therapy (ERT) is not clear from blood and urine tests alone, but may be more clear in comparisons of kidney biopsies performed before and some time after ERT has been initiated, and this is what we are focusing our study efforts on. The purpose of this study is to obtain your permission to allow us to study the kidney biopsy tissues (collected for medical reasons) after the regular routine studies have been completed. Through our special research measurements and additional study, we hope to be able to see and measure very specific changes in the kidney tissues from Fabry patients taking ERT. We also hope that through these studies of what happens within the kidney before and after starting ERT, we are able to reveal valuable information about the importance of factors like your age that you started ERT, the amount or dosage of ERT, and any differences seen between males and females.

This research study is for participants who have an inherited neuromuscular disorder or neurogenetic disorder, or family members who are unaffected by such disorders

This is a multi-center, prospective, observational cohort registry study looking at kids and their relatives with Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT).

The objective is to conduct a longitudinal investigation of the natural history, complications, and therapeutic outcomes in people with acute and cutaneous porphyria.

The purpose of this research project is to develop a registry and database of families with neurodevelopmental disorders.

The Syner-G regimen research study seeks to evaluate the use of a combination of a medication called miglustat and a ketogenic diet for treatment of the gangliosidoses to learn if this combination will provide improved clinical outcomes compared to what we currently know about the natural course of the disease.

This is a research study documenting the natural history of disease in patients with GM1 or GM2 gangliosidosis. The information collected will be a way to evaluate disease progression and create a disease stage and severity index. Our goal is to use the data collected to measure the effectiveness of any treatments that are developed in the future.

The purpose of this study is to determine how different bladder management methods affect the quality of life for young people with spina bifida. We hope to find out if certain bladder management methods are associated with a better quality of life. This information could help doctors make better treatment decisions and counsel young people living with spina bifida.
