This study is being conducted to learn more about how the brain's learning systems work in teenagers who use cannabis (marijuana). Our goal is to see if these brain systems can predict how well a teen might do in a treatment program for marijuana use called contingency management. Contingency management is a type of treatment that uses rewards to encourage avoiding marijuana. We need your help to find markers in the brain that predict cannabis use disorder symptoms and treatment success.You and your child may be eligible if…You are 18 years or olderYour child is 14-17 years oldYour child uses cannabis (marijuana)Your child can have an MRI brain scan (for example, they don’t have metal in their body)

This pivotal investigation is a prospective, multicenter, non-randomized, single-arm study to evaluate the safety and effectiveness of the ASG device for the treatment of de novo Type A aortic dissections in patients considered to be high-risk for open surgical repair.THIS STUDY IS ENROLLING BY INVITATION ONLY   - Patients considered to be at high-risk of open surgical repair for aortic dissection will be identified at each site by the Aortic Treatment Team and contacted about study participation. 

The purpose of this study is to assess the body composition and growth measurements at time of NICU discharge of preterm infants who experienced acute kidney injury during their hospitalization, and to compare this with matched controls who did not experience acute kidney injury.THIS STUDY IS ENROLLING BY INVITATION ONLY - All patients admitted to the Riley Hospital Maternity Tower NICU from the date of IRB approval will be screened for eligibility. Outborn infants will be included if admitted within the first week of life. On a weekly basis, research staff will review the census at Riley Hospital Maternity Tower NICU to identify patients nearing discharge (~3-4 weeks prior to discharge). Cases and controls will be determined based on protocol criteria. If the infant is determined to meet eligibility criteria for either group, the parent(s)/caregiver(s) will be approached for consent by research staff or one of the investigators approximately 2 weeks prior to anticipated discharge. The study will be discussed, and participation will be offered.
