CHLA Research Study on Cerebrovascular Impact of Acquired Anemia
Anemia is a condition where the body is not making enough red blood cells to transport oxygen. The objective of this study is to learn how anemia may affect the oxygen delivery to the brain as measured by magnetic resonance imaging (MRI). By studying this, we hope to better identify people who may benefit from correction of their anemia.
Healthy Fetal and Placental Development
A newborn is truly a miracle! In the mother's womb, many factors work together to ensure healthy development for the baby. Scientists and doctors at USC/Children's Hospital Los Angeles are trying to understand how a baby's development in the womb impacts its health across its life. This helps us provide better therapies and treatments for babies with birth defects so that they can lead healthy lives. <br>
Cognition as a moderator of motor learning post-stroke
The goal of this study is to understand how an individual’s cognitive function and brain structure may influence their ability to learn a new walking pattern. We hope to learn how people can best learn a new walking pattern when parts of the brain are damaged and cognitive function may be impaired.
Healthy Minds Volunteer Database
The Healthy Minds Volunteers (http://healthyminds.usc.edu) help research labs at the University of Southern California. These labs are working towards a greater understanding of how aging can affect physical, mental and emotional health. The goal is to learn how we can maintain healthy minds and bodies across our lifespan.
VNS Therapy for Treatment-Resistant Depression
The purpose of this study is to track active VNS Therapy treatment in subjects with Treatment-Resistant Depression (TRD) and to better understand the reduction in the severity of baseline TRD symptoms. Data will be collected on your responses to study treatments, quality of life, productivity, and your use of healthcare services. Your participation in this study will consist of evaluations by the study doctor (or his/her designee), who will review your past and current medical and psychiatric history, and several questionnaires which you will complete during several follow-up visits over time.

Diagnostic Fetal Imaging on a Novel MRI Scanner
We are seeking pregnant adults to participate in a study evaluating a novel, quieter MRI scanner. We hope to develop better ways for doctors to screen pregnancies for possible fetal problems and to make MRI of unborn babies more comfortable and even safer. Images will be collected at 3-6 fold lower magnetic field strength (0.55 Tesla) than a standard MRI. Participation in this study will involve being imaged on a lower field strength MRI scanner located in the Michelson Building at the USC University Park Campus. Participants will be compensated for their time.
A Placebo-controlled Study of a Targeted Immune Therapy Drug in Subjects with Moderate to Severe Ulcerative Colitis (UC)
The primary objective of this study is to study the effectiveness of a novel targeted immune therapy (biologic) called LY3074828 in treating moderate to severe ulcerative colitis. This study will take place over 120 weeks and all study visits and procedures will be provided at no cost to you. During the initial part of this study, patients will either receive LY3074828, or placebo ("dummy" treatment). Patients who receive placebo initially will have the opportunity to receive the study drug LY3074828 later in the study.
Long-Term Registry of Patients with Urea Cycle Disorders (UCDs)
The main goal of medical management of Urea Cycle Disorder (UCD) patients is to prevent chronic or acute hypperammonemic states leading to central nervous damage- which requires a restriction in dietary protein intake and using nitrogen scavenging agents if diet alone does not help the patients.The objective of this study is to characterize the demographic of the patient population diagnosed with UCD. Another objective is to track growth and neuro-cognitive outcomes for patients with UCDs. Patient participation includes the collection of retrospective and baseline data including ammonia and glutamine levels. Age appropriate questionaires will be given for completion by subject or parent. . Data will be collected on all individuals who are enrolled. The patient population are patients with an established or suspected diagnosis of UCD. The patient or legally acceptable representative must also sign and release an informed consent/HIPPA Authorization and medical records.The study procedures are for each study personnel to be trained for all documentation, baseline visits and enrollment for patients, and retrospective data for ammonia values obtained from the patient will be entered in the registry. The outcome variables will be the control of blood ammonia levels and the frequency of the serious adverse events (SAEs). Blood ammonium levels, and the frequency of hyperammonemic crisis will be observed during this study.The statistical analysis plan (SAP) will show details of all analysis and presentation of study data. Data will be shown to patients who attend the baseline visit, and analysis will be based on all the patients who are enrolled. Post baseline values or change from the baseline outcome variables will be summarized by UCD medication with statistics and graphical presentations.
