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.
Does pulling out work for birth control?
<p><strong>Why Withdrawal?</strong></p><p class="font_8">“Pulling out” or withdrawal is a method that people use to prevent pregnancy. It's been around for a long time and lots of people use it. However, we--scientists--STILL don't know very much about how to use it and how effective it really is. Some men have used withdrawal their whole lives without any unwanted pregnancies, whereas others have been less successful…</p><p class="font_8"><span style="font-weight: bold;">We want to know why!</span></p><p><strong>Our Questions:</strong></p><ul class="font_8"><li><p class="font_8">If withdrawal is used correctly, is there sperm released in the pre-ejaculatory fluid ("pre-ejaculatory fluid") that can make a woman pregnant?</p></li><li><p class="font_8">What makes someone more likely to have sperm in their pre-ejaculate?</p></li><li><p class="font_8">What affects whether someone will have sperm in their pre-ejaculate?

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>
Effect of ResQFoam to Slow or Stop Severe Internal Bleeding in Trauma Patients
Trauma is the leading cause of death in people younger than 45 years. Unfortunately, 40-50% of severely injured patients with internal bleeding die, even after reaching the hospital. This clinical study is about whether ResQFoam can help slow or stop severe internal bleeding in the abdomen (belly area) while the patient is being brought in for surgery. ResQFoam is a device that injects a liquid foam into the abdomen. The foam expands and forms a seal around the bleeding wounds, reducing blood loss.
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.

A pilot study of safety and efficacy of spectroscopic diagnosis of pancreatic lesions (Spy Panc)
The objective of this study is to determine if a minimally invasive optical probe can accurately predict a histological diagnosis of dysplastic or malignant tumor cells in solid lesions of the pancreas. If effective, this optical probe would facilitate the detection of malignant and pre-malignant pancreatic lesions. This would lead to more accurate decision-making as to which patients require surgical resection versus patients who should be spared from major surgery.
