This is an observational study that create a patient registry by collecting data, biosamples (blood and stool samples) on patients who have been diagnosed with Clostridiodes difficile (C difficile). The registry will include data about CDI episodes, CDI related symptoms, participant experience. The study will last 42 days and there will be 2-3 visits.

Hematopoietic cell transplantation (HCT) and solid organ transplantation (SOT) recipients are at high risk for respiratory viral infection (RVI). This study aims to establish a comprehensive RVI diagnostic and disease progression predictive model in children undergoing HCT and SOT. Findings will result in the first ever evidence-based pediatric guidelines.

This is a prospective observational cohort study that will create a patient registry by collecting data on patients who receive REBYOTA to prevent recurrence of Clostridioides difficile infection (CDI). The registry will include data about CDI episodes, CDI related symptoms, healthcare resource utilization (i.e., hospitalizations and re-admissions) and this data will be collected up to 6-months after receiving REBYOTA™.

The purpose of this study is to compare the safety and efficacy of the PMX cartridge ( Toramyxin) (in Addition to Standard Medical Care for Patients with Endotoxemic Septic Shock:
Eligible and consented subjects will be randomized to receive either the PMX cartridge (administered twice for 1½ to 2 hours per treatment session approximately 24 hours apart) plus standard medical care or standard medical care alone. For all subjects in whom treatment has been initiated, a follow-up visit (if they are still in the hospital) or a telephone call will be completed at Day 28 (or later) to determine their mortality status. In surviving subjects, a follow-up visit or telephone call to determine their mortality status will also take place at approximately three months (i.e. Day 90) and 12 months after the subject was randomized.

This research study is being done to determine whether it is safe to give a kidney transplant from a donor with hepatitis C to a patient without hepatitis C. This study is looking for participants in need of a kidney transplant who are willing to accept a kidney from a patient with hepatitis C.

Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract. infection (LRTI) among infants and young children, resulting in annual epidemics worldwide. Despite more than 50 years of attempted vaccine development, there are no licensed vaccines. While RSV prevention exists in the form of a specific RSV IgG (palivizumab) requiring 5 once monthly injections, it is licensed only for infants who experience the greatest morbidity and mortality from RSV: preterm infants born ≤ 35 weeks GA, children with chronic lung disease of prematurity, children with hemodynamically significant congenital heart disease. EDP-938 is a novel, orally administered, non-fusion replication inhibitor of respiratory syncytial virus (RSV) that is being developed as a potential treatment for RSV infection.

The Pediatric Intensive Care Influenza Study #2 (PICFLU2) is a multiyear, multicenter prospective observational study in patients aged ≤ 21 years hospitalized in pediatric Intensive Care Units (PICUs) and Stepdown (or intermediate) Care Units (SDUs) in the US designed to evaluate of the immunobiology of influenza virus-related critical illness in young hosts.

This study will repurpose medications that have already been approved for use by the Food and Drug Administration (FDA) for other indications to treat non-hospitalized patients that are at least 30 years old with mild to moderate COVID-19. The effectiveness of reducing COVID-19 symptoms will be evaluated by comparing the medication to a placebo or fake treatment with no therapeutic value. Participation will last about 180-days and all study visits are designed to be performed over the phone or remotely. Participants will be compensated for their time and participation in this research study.
