There is an urgent public health need to reduce our reliance on opioids for effective long-term pain management, particularly in knee osteoarthritis (KOA). This effectiveness trial will compare recommended treatments to reduce pain and functional limitations in KOA and identify clinical and patient-level factors associated with treatment response. These results will lead to improved patient selection for treatment and inform evidence based guidelines by offering well-tested, effective, non-opioid alternatives.

Osteoarthritis (OA) is a leading cause of disability and chronic pain that reduces physical activity and daily activities. In this clinical research study, the goal is to learn more about geniculate artery (located in the knee) embolization (GAE) treatment to see if it will reduce pain as well as stiffness and difficulty performing daily activities caused by knee OA and if it can be performed safely.

The primary objective for this observational study is to collect general and medical data from children, adolescents, and young adults who had pediatric onset rheumatic disease. This data will be used to evaluate the long-term safety and efficacy of therapeutic agents used to treat these diseases. This information will allow investigators to accurately report and follow changes in current medication use patterns and compare these to proposed standards and current treatment recommendations. The use of a single registry will allow for more analysis of the different therapeutic agents by allowing them to be compared to each other.

This research study aims to learn more about the causes of Systemic Juvenile Idiopathic Arthritis (sJIA) including its complications such as Macrophage Activation Syndrome (MAS) and sJIA associated lung disease and identify new therapeutic targets. The study is asking for biological samples from those diagnosed with sJIA as well as their family members.

We are studying different questionnaires used to measure symptoms and activity limitations that are linked to thumb arthritis. We are also studying ways to measure thumb position sense in persons with thumb arthritis.

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.

The purpose of this study is to develop a cohort of patients with early scleroderma, and to collect data on clinical outcomes, radiological tests, laboratory tests and to obtain biological specimens for testing.We hope to explore medical care and the impact of SSc on patients' daily lives through various questionnaires that will be collected during study participation. By looking at all of the areas mentioned, we hope to find out information about SSc that will help treat future patients, develop new treatments, and work towards a cure.
