Primary sclerosing cholangitis (PSC) is a rare liver disease that damages the liver's bile ducts. Bile ducts are tiny tubes that carry bile from the liver to the small intestine. Bile is a liquid produced by the liver that helps us absorb and use the nutrients in the food we eat. In people with PSC, the bile backs up into the liver and will damage it, causing scarring of the liver. The purposes of this study are to: * Collect medical and other data to learn more about PSC, how it progresses, and identify factors that may cause the disease to progress more quickly. * Ask questions about how PSC symptoms affect your child's life to learn more about its impact on your child's daily functioning * Children with PSC who are seen at one of the participating clinical sites in the Childhood Liver Disease Research Network (ChiLDReN) will be asked to contribute information, DNA, and other specimens. The information and specimens will be available to investigators to carry out approved research aimed at learning more about the possible causes and long-term effects of PSC. Read Less

This study is being conducted to help the investigators better understand how the new FDA approved medication Edaravone (also known as Radicava) works in subsets of patients with ALS. The investigators are also trying to understand if there are specific ALS patients, with different presentations of ALS, who might benefit most from this medication. Also, the investigators are following specific biomarkers to determine the optimal treatment duration in patients with different forms of ALS There is no study medication being offered in this trial. Edaravone is prescribed as part of regular care. In this trial we are collecting blood, urine, and spinal fluid samples in ALS patients who are taking Edaravone and ALS patients who are not taking Edaravone to measure certain markers that could indicate why the drug may be working in a specific type of ALS.

This study is being done to determine if stereotactic body radiotherapy (SBRT) when delivered to all sites of disease in participants with 1-5 metastases will increase the length of time before participants' disease gets worse. Read Less

To establish the safety and effectiveness of the Edwards PASCAL Transcatheter Valve Repair System in patients with degenerative mitral regurgitation (DMR) who have been determined to be at prohibitive risk for mitral valve surgery by the Heart Team, and in patients with functional mitral regurgitation (FMR) on guideline directed medical therapy (GDMT) Read Less

Little is known about the factors that cause biliary atresia nor the factors that influence disease progression. The purpose of this study is to collect the pertinent clinical information, genetic material and body fluid samples to enable investigators to address the following aims: To identify the gene or genes implicated in the etiology of BA; To identify polymorphisms that may be important in disease progression such as HLA polymorphisms; To characterize the natural history of the older, non-transplanted child with BA.

The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: * To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. * To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. * To characterize the Pompe disease population. * To evaluate the long-term effectiveness of alglucosidase alfa.

Biliary atresia, idiopathic neonatal hepatitis, and specific genetic cholestatic conditions are the most common causes of jaundice and hyperbilirubinemia that continue beyond the newborn period. The long term goal of the Childhood Liver Disease Research Network (ChiLDReN) is to establish a database of clinical information and plasma, serum, and tissue samples from cholestatic children to facilitate research and to perform clinical, epidemiological and therapeutic trials in these important pediatric liver diseases.

The goal of this clinical trial is to characterize to understand the effects of a type of cell therapy called Chimeric Antigen Receptor T lymphocyte (CAR T) therapy in adult patients with the autoimmune disease dermatomyositis. This study will utilize a technology that modifies a type of white blood cell called the cytotoxic T lymphocyte-this T cell normally functions in the immune system to kill infected or potentially harmful cells in the body. In CAR T therapy, the patients' white blood cells are harvested and the cytotoxic T cells are isolated and modified such that they are programmed to kill any cell that has a protein structure called "CD19" on its outer surface (membrane). Since the CD19 protein is only present on a type of white blood cell called the B lymphocyte, when these "re-engineered" cytotoxic T lymphocytes are then given back to the patient (by an infusion), these cells will seek out and kill essentially all of the patient's B cells. B cells are an important part of a person's immune system and have many functions, including the production of antibodies. It is thought that, in dermatomyositis and other autoimmune diseases, a tiny subset of these B cells plays a large role in making autoantibodies (antibodies directed against the patient's own tissues) and causing disease. The idea is that the therapy will "wipe out" all/most of the B cells in the patient so that they can make an entirely new set of B cells to recreate a functional immune system without the autoimmune disease. The main questions the study intends to answer are: * Understanding how well patients tolerate undergoing this therapy in terms of side effects; * Getting an early idea if this therapy can help certain aspects of the autoimmune disease, including inflammation in the skin, muscles, and lungs; Read Less

PTSD occurs in up to 17% of post-9/11 US Service Members and is associated with long-term functional impairment, family problems, unemployment, and suicidality. Trauma-focused therapies (TFTs), such as Prolonged Exposure (PE), result in significant relief for many. Yet, TFTs are not equally effective for everyone. An important minority (\~40%) will retain their PTSD diagnoses after treatment, and many discontinue treatment prematurely, especially post-9/11 Service Members. TFTs are also more effective in addressing symptoms than psychosocial functioning. More work is needed to improve the consistency and potency of TFTs. Partnering with significant others may provide a powerful method for helping individuals get more out of their PTSD treatment. Observational research shows that relationship factors can help patients initiate, stay in, and experience greater benefit from PTSD treatment. Veterans that were surveyed experienced greater treatment gains when they shared more about their treatment with loved ones and when loved ones accommodated less for PTSD symptoms. Despite the promise of partner-involved interventions, there is no couples approach to PTSD treatment that has demonstrated superior outcomes to individual-only treatment models (i.e., TFTs). To address this gap, the investigators have completed a series of partner-assisted PTSD treatment studies, leading up the current proposal (Partnered PE, PPE). The investigators found that treatment completion rates were better than routine clinical care, and the treatment led to large improvements in participants' functioning, PTSD symptoms, and romantic functioning. For this proposed study, the primary objective is to conduct a randomized controlled trial (Research Level 3; larger-scale clinical trial) to test the superiority of PPE to standard PE among post 9/11 Veterans. The investigator's primary hypothesis is that PPE will lead to greater improvements in psychosocial functioning than standard PE. Secondary and tertiary aims examine posttreatment clinical outcomes (PTSD, depression) and intimate partner outcomes (relationship functioning, distress, caregiver burden, and psychosocial functioning), as well as examine strategies for PPE implementation. In exploratory aims, the investigators will examine the stability of group differences, treatment completion rates, the role military sexual trauma history, and treatment mechanisms. Read Less
