The overall objective of the study is to determine the best dose of Vitamin D supplementation in children who have asthma and are overweight or obese to achieve a normal vitamin D level.

This study is for patients with recurrent/progressive medulloblastoma, which is a type of childhood brain tumor. Participants in this study will receive intravenous (IV, into the veins) bevacizumab and intrathecal (into the spinal fluid) or intraventricular (into the fluid surrounding the brain) etoposide and cytarabine in combination with five oral (taken by mouth) chemotherapy drugs as a possible treatment for recurrent/progressive medulloblastoma. Total study duration is about 1 year and depending on how well a participant tolerates the medications and the response of the disease, the patient may continue the treatment after the first year.

Alzheimer's disease and Epilepsy may affect over 80% of individuals that have Down syndrome by the age of 60. Biomarkers found in the blood can enhance our understanding of the earliest changes linked to disease and may enhance clinical detection and healthy aging for individuals with Down syndrome.

The purpose of this study is to discover early neurobiological processes underlying the transition from healthy aging to disease. Our research team has developed technology that allows detection of small changes in the brain that get transferred to the blood.

We are recruiting individuals that either have or do not have Down syndrome for this biomarker study. Participants should be between the ages of 6 months and 85 years old and may include mothers and siblings of a child with Down syndrome. Infants and children will require consent form a parental or legal guardian.

Each participant will provide a blood sample for research purposes. We will also gather some basic health information about senses, habits, exercise level and smoking/vaping exposures.

The largest published COVID-19 pediatric series to date included only 13 patients considered to be critically ill and only described the Chinese outbreak. There are essentially no data outside of this and nothing to begin to understand the prevalence of severe/critical pediatric COVID-19, the risk factors associated with this illness, outcomes from COVID-19, and factors (patient or treatment) that may be associated with an improved or worsened outcome. This study will identify all children admitted to an inpatient unit with a diagnosis of COVID-19. Clinical data will be collected through medical record review to describe in detail the demographics and clinical characteristics, including clinical course and treatment, of infected children who require hospitalization.

Babies that are born extremely prematurely are at higher risk of developing chronic (long term) lung disease (CLD) and other complications (problems). The purpose of this study is to test the safety and effectiveness of an investigational drug called mecasermin rinfabate (rhIGF-1/rhIGTBP-3) or SHP607. The researchers want to find out if SHP607 can help reduce the risk of chronic lung disease in babies born prematurely and if it can help reduce the risk of other complications.

Pediatric traumatic injury (PTI) – defined as unintentional injury requiring hospitalization and, often, extended periods of physical and emotional recovery – is experienced by 300,000 children in the U.S. annually. Roughly 20-40% of children and caregivers develop posttraumatic stress disorder (PTSD) and/or depression following PTI, yet most U.S. trauma centers fail to provide even basic mental health screening post-injury. It is critical to advance our knowledge of available mental health services in trauma centers for this frequently overlooked population to accelerate their physical and emotional recovery. In this project, trauma center providers across the U.S. will complete a survey and a qualitative interview to assess their current protocols and resources available to screen and treat children and families' mental health in the aftermath of PTI, as well as their opinions regarding feasibility of implementing protocols to better address the emotional health recovery within this population.

Youth with one or more chronic diseases are at increased risk of further complications, disease, or even early death as they enter their adult years. Recent increases in both asthma and obesity among youth have led to high health care utilization, increased health-related complications, and expanded risks of subsequent cardiovascular disease burden. The research team will develop educational content in core areas (e.g., fatigue, physical activity) for Managing AsThma AnD Obesity Related Symptoms (MATADORS), an mHealth technology-enhanced nurse-guided intervention. Youth with asthma and obesity and their primary caregivers will participate in interviews to explore their perspectives on barriers, facilitators, needs, and preferences toward adopting health behaviors, medication adherence, disease awareness, symptom self-management behaviors, and utilization of a mobile smartphone platform. Additional details on content availability, delivery approaches, system needs, and functionality will be explored through semi-structured interview questions. Health care providers (physicians, nurses, nurse practitioners, dietitians, and respiratory and exercise therapists) will be invited to participate in interviews to seek their input on patient-caregiver needs, priority clinical focal areas, recommendations for symptom self-management, and preferences for intervention delivery. Interview findings will be used to inform intervention and app design. Providing youth with strategies to enhance symptom self-management may result in decreased symptom prevalence, improved quality of life, and long-term reduction of cardiovascular morbidity and mortality as they move into adulthood.

The aim of this multi-site study is to evaluate the effectiveness of mHealth intervention strategies for improving anti-epileptic drug adherence in caregivers of young children with epilepsy. A 2-month baseline period will be followed by two stages. In Stage 1 (3-months), caregivers will received either 1) a mHealth education module and automated digital reminders or 2) the mHealth education module, automated digital reminders, and individualized adherence feedback based. In Stage 2 (2-months), caregivers will either receive 1) continued individualized adherence feedback or 2) individualized adherence feedback and a mHealth problem-solving module. The primary outcome is electronically-monitored adherence. Secondary outcomes include seizure severity/frequency, quality of life and healthcare utilization.

This is a clinical research trial that will evaluate whether an investigational drug called dupilumab (given by injection) is safe and effective in children with severe atopic dermatitis.

Early intervention for infants and toddlers with or at-risk 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 6 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.
