Viral Load in Blood and Lymph Tissues in People Living With HIV
Recruiting
This is a study to determine the effect of the human immunodeficiency virus (HIV) on lymphoid tissues (e.g., lymph nodes) as compared to peripheral white blood cells. We have shown in previous studies that the lymph node is a major site of accumulation of HIV in the body, as well as being a site where much of the viral replication occurs which leads to the destruction of the body's immune system. To better understand the role of the lymph node in HIV infection and destruction of one s immunity,... Read More

Studies of Brain Function and Course of Illness in Pediatric Bipolar Disorder
Recruiting
This study seeks to learn more about the symptoms of severe mood dysregulation in children and adolescents ages 7-17. Children and adolescents with severe mood dysregulation (SMD) display chronic anger, sadness, or irritability, as well as hyperarousal (such as insomnia, distractibility, hyperactivity) and extreme responses to frustration (such as frequent, severe temper tantrums). Researchers will describe the moods and behaviors of children with these symptoms and use specialized testing and b... Read More

MRS Measurement of Glutamate and GABA Metabolism in Brain
Recruiting
This study will use magnetic resonance spectroscopy (MRS) to measure in the brain the transfer of \[13\]C as it is naturally metabolized from glucose to specific chemical transmitters. From this method, we can measure the rate of production of an important excitatory neurotransmitter (glutamate) as well as an inhibitory neurotransmitter (GABA)....

Cognitive Task Development and Implementation for Functional MRI Studies
Recruiting
Background: * Drugs of abuse have effects on mood, behavior, thinking, and decision making that may encourage people to continue using them and make it difficult for them to stop. Researchers who study these effects are interested in developing new tests to evaluate how drugs and drug use affect different areas of the brain. * Magnetic resonance imaging (MRI) scans allow researchers to study brain activity and changes to brain function. When specific psychological tests are performed during fun... Read More

Pathogenesis and Genetics of Microphthalmia, Anophthalmia and Uveal Coloboma (MAC)
Recruiting
Background: - Uveal coloboma is a condition where the eye does not form normally. It occurs early in the fetus s development during pregnancy. It can lead to different kinds of eye problems, including blindness. Uveal coloboma is part of a spectrum of developmental eye conditions that include anophthalmia and microphthalmia, typically referred to as "MAC". Several genes have been linked to MAC, but the cause of most causes are hard to find. Researchers want to study the genes of people who have... Read More

Care of the Prostate Cancer Patient and Prospective Procurement of Prostate Cancer Tissue
Recruiting
Background: Prostate cancer is the most common noncutaneous cancer among men in the U.S. Researchers want to study blood, tissue, and fluid samples of people with prostate cancer. This will help them understand any changes in cells and genes. These changes might lead to the development and progression of prostate cancer. Researchers think the study could lead to new treatments. Objective: To understand the changes in cells and genes that lead to the development and progression of prostate can... Read More

Evaluation of Dosing Procedures of Chemotherapy Treatment (Carboplatin) With the Contrast Agent Iohexol
Recruiting
This trial studies how well iohexol works in helping doctors calculate the dose of carboplatin given to patients with cancer. Drugs used in chemotherapy, such as carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Understanding how to best calculate the dose of carboplatin given to patients with cancer may help doctors learn how to improve the use of carboplatin in the future.

Increasing Gait Automaticity in Older Adults by Exploiting Locomotor Adaptation
Recruiting
The investigators will test the following: 1) the extent of locomotor adaptation improvement in individuals aged 65 years and older; 2) the association between initial walking automaticity (i.e. less PFC activity while walking with a cognitive load) and prefrontal-subcortical function (measured via neuropsychological testing); and 3) whether improvements in locomotor adaptability result in improvements in the Functional Gait Assessment (FGA), a clinically relevant indicator of dynamic balance an...

Longitudinal Early Advance Care Planning Discussions and Documentation (LEADD) Program: An Exploratory Study in Adolescents and Young Adults (AYAs) Receiving Hematopoietic Stem Cell Transplant
Recruiting
Background: For adolescent and young adults (AYAs) with certain life-threatening illnesses, hematopoietic stem cell transplant (HSCT) provides the best chance for cure and survival. HSCT is a life-saving therapy, but this treatment also comes with significant risks. Given these risks, it is imperative that patients and their families have the opportunity to share their values, priorities, and goals through advance care planning (ACP) to ensure that the care they receive through the transplant p...

Collaborative Care for Polysubstance Use in Primary Care Settings (Co-Care)
Recruiting
The purpose of this trial is to test the efficacy of a collaborative care intervention to address opioid- and/or stimulant-involved polysubstance use in adult primary care patients with moderate to severe substance use disorders (SUD). The primary aims are to reduce days of opioid use (illicit or nonmedical opioid use), days of illicit stimulant use (cocaine, methamphetamine), and days of heavy alcohol use.

Testing the Addition of Anti-Cancer Drug, Cetuximab, to Standard of Care Treatment (Pembrolizumab) for Returning or Spreading Head and Neck Cancer After Previous Treatment
Recruiting
This phase III trial compares the effect of adding cetuximab to pembrolizumab versus pembrolizumab alone in treating patients with head and neck squamous cell carcinoma (HNSCC) that has come back after a period of improvement (recurrent) and/or that has spread from where it first started (primary site) to other places in the body (metastatic). Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This... Read More
