This study is for patients who have been diagnosed with relapsed or refractory CD22+ B-Acute Lymphoblastic Leukemia (B-ALL). The overall goal of this study is to find out what effect, good and/or bad, the drug inotuzumab ozogamicin has on children and young adults with relapsed or refractory B-ALL. Participants can expect to be on this study for up 2 months and followed for up to 5 years.

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.

The purpose of this research study is to evaluate Parent Child Interaction Therapy (PCIT) delivered via telehealth for young children with autism spectrum disorder (ASD) and disruptive behavior problems. Participants will go through a screening to determine eligibility. Eligible families who choose to participate will complete 3 in-person visits at MUSC and may receive 10 telehealth therapy sessions, at no cost. Families will be compensated for their time.

The purpose of this research study is to evaluate Parent Child Interaction Therapy (PCIT) delivered via tele-health for young children with a developmental diagnosis (ex. suspected or diagnosed autism, ADHD, global developmental delay, etc.) and disruptive behavior problems. Participants will go through a screening to determine eligibility. Once screening is complete, participants will complete a pre-therapy assessment in clinic, followed by 10 telehealth sessions one time per week, at no cost. Participants will then be asked to complete an in-person post-therapy assessment and follow-up questionnaires will be re-administered 3 months following the completion of therapy. Families will be compensated for their time.

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.

This study is for patients that have been diagnosed with leukemia. This study is called a screening study and we are doing this study to find better ways to diagnose and treat leukemia in children, adolescents and young adults. Bone marrow, blood, and medical information about participant's cancer and treatment will be collected. Participants can expect to be on this study for 5 years.

This study includes a longitudinal mixed methods study of 360 YYA with diabetes in SC, CO, and WA conducted with SFS 1 participants. SFS 2 will have two parts: (1) an intense, longitudinal study consisting of two 14-day assessment periods spaced 9 months apart which will include CGM, EMA, accelerometry, and surveys in all participants (the EMA study); and (2) a concurrent events qualitative study with a subset of participants (30 T1D, 15 T2D) who will complete 13 one-on-one, semi-structured interviews throughout the 9-month assessment period (the qualitative study).

The purpose of this study is to find out whether a web-based intervention using a mobile app is helpful for teens and young adults with sickle cell disease (SCD) in learning how to care for and manage their symptoms. 272 teens and adults with SCD will be enrolled in this study which is being conducted at the Medical University of South Carolina in Charleston SC., East Carolina University in Greenville NC., University of Miami in Miami FL., and the University of Alabama in Birmingham AL.

Early intervention for infants and toddlers with or at an elevated likelihood for autism spectrum disorder can promote developmental skills and improve lifelong outcomes. Yet, many children with ASD are not diagnosed until after age 3. In order to improve early detection of ASD, we are investigating very early predictors of social communication challenges in infants as young as 1 week to 4 months of age.

This research study examines how the development of attention and motor skills in the first year of life is associated with the emergence of social and communication skills in three groups of infants: infants who are first born or who have a sibling with no developmental delays, infants who have an older sibling diagnosed with autism spectrum disorder, and infants who were born preterm.

This study is for patients with acute leukemia or myelodysplastic syndrome (MDS). This study is being done to help understand whether a haplo related donor or a MUD HCT for people with acute leukemia or MDS is better or if there is no difference at all.
