This research study aims to learn more about children and adolescents who have a shiga toxin-producing E. coli (STEC) infection. E. coli is a type of bacteria found in the intestines. Although most types of E. coli are harmless, some produce toxins that can make children sick. This study will assess what type of treatment is best for this infection.

The purpose of this study is to see if taking depemokimab is safe and effective in treating Hypereosinophilic syndrome (HES) in adults (≥18 years) with uncontrolled HES receiving standard of care (SoC) therapy. The study will last approximately 52 weeks and is a placebo-controlled, double blind, multicentre study.

Each year, roughly 600,000 patients served in U.S. trauma centers develop posttraumatic stress disorder or depression after traumatic injury, but few receive mental health follow-up care. The Trauma Resilience and Recovery Program is a sustainable, stepped-care model that has addressed the mental health needs of over 8,000 patients in four Level I-II trauma centers and is being adopted by 8 additional trauma centers in the Carolinas. This study will examine the effectiveness and implementation of TRRP with a diverse sample of 350 patients served at The George Washington University hospital.

This study is for subjects that have been newly diagnosed with diffuse large B cell lymphoma (DLBCL). This study is testing an "investigational" (not yet approved by the Food and Drug Administration (FDA)) combination of the drug zanubrutinib (BRUKINSA™) and a standard chemotherapy treatment called R-CHOP. This study will test the how well the drug combination works and how safe it is. The subject will be given the study drug combination in 21 day cycles. At any given visit, the subject may undergo procedures, such as a physical exam, blood samples, bone marrow biopsies, and imaging scans. The subject may remain in the study for up to approximately 2 years.

This study will compare WATCHMAN FLXTM ("DEVICE") to a category of OAC called non-vitamin K antagonist oral anticoagulation, also known as NOACs ("CONTROL"). NOAC medications include Pradaxa® (dabigatran), Eliquis® (apixaban), Xarelto® (rivaroxaban), or Savaysa® (edoxaban).The study will research the safety and effectiveness of the WATCHMAN FLXTM device compared to treatment with NOAC therapy to determine if it works for patients with your type of atrial fibrillation who require treatment for potential blood clot formation (thrombus) in the LAA.

People who experience a stroke often have problems performing many different tasks during daily life. Most studies investigating stroke recovery and rehabilitation focus only on one type of task. The purpose of this research study is to measure individuals' function in many areas that can be affected by a stroke, such as their balance, mood, memory, reaching, and speech. This study will also track changes that can occur with task performance over time.

The purpose of this study is to examine the relationship between reflexes in the leg and the presence of neuropathic pain. The researchers are recruiting 30 individuals with spinal cord injury (SCI) total, 15 individuals with neuropathic pain due to SCI and 15 individuals without neuropathic pain. For this portion of the study, there are 2 visits. The first visit will examine cutaneous reflexes in the leg. During the second visit, the study team will assess sensation in the leg and administer questionnaires about pain, functioning, and quality of life.

The purpose of the second part of the study is to examine the effect of reflex training in the leg to decrease neuropathic pain. For this, the researchers are recruiting 15 individuals with neuropathic pain due to spinal cord injury to participate in the reflex training procedure. The study involves approximately 50 visits with a total study duration of about 6.5 months (3 months for baseline and training phases followed by 1 month and 3 month follow-up visits).

Sensory stimulation has been shown to enhance rehabilitation outcomes. However, most sensory stimulation devices interfere with natural hand tasks. Thus, a new wearable stimulation device has been developed to deliver imperceptible vibration to wrist skin. This study is to evaluate the community use of the device for patients with neurologic movement disorders. Participation will include wearing the provided device and charging the device every night. The knowledge regarding community use of the device may contribute to improving the device functionality and usability for future users of the device.

This study is for patients who have had surgery for pancreatic neuroendocrine tumor (pNET). This study is being done to find out if giving chemotherapy after surgery is better or worse than the usual approach for patients that have had surgery for pNET.

The purpose of this study is to create a de-identified, public use,
repository of data of Chronic Obstructive Pulmonary Disease (COPD)
patients with by Alpha-1 antitrypsin deficiency (AATD), a rare genetic
condition that can cause COPD and emphysema.
