Neurobiology of Suicide

Background There are no good treatments for people considering suicide. Researchers want to study suicide with questions, blood tests, brain imaging, and sleep studies. They hope to better understand suicide, so they can help suicidal people. Objective To understand what happens in the brain when someone has thought about or …

Human Immune Response to Ixodes Scapularis Tick Bites

Background Each year, the number of cases of tick-borne diseases increases. The deer tick (Ixodes scapularis) is the vector of at least 7 pathogens that cause human diseases, including Lyme disease. Researchers want to learn more to help them develop vaccines against ticks in the future. Objective To learn how …

Pulmonary Embolism - Thrombus Removal With Catheter-Directed Therapy

PE-TRACT is an open-label, assessor-blinded, randomized trial, aiming to compare catheter-directed therapy (CDT) and anticoagulation (CDT group) with anticoagulation alone (No-CDT) in 500 patients with submassive PE, proximal pulmonary artery thrombus and right ventricular dilation.

De-escalation of Adjuvant Radiation for Low-Risk HPV Oropharyngeal Cancers

The goal of this clinical trial is to learn whether for intermediate-risk patients who have undergone Transoral Robotic Surgery for HPV/p16(+) oropharyngeal cancer and have minimal smoking history, whether these patients can be treated with a lower-than standard dose, with omission of the primary site in the oropharynx. The main …

Studies of Blood Flow to the Brain During Thought

The purpose of this study is to use brain imaging technology to measure changes in blood flow to areas in the brain as individuals perform intellectual tasks. This study will use functional magnetic resonance imaging (fMRI) to examine blood flow to areas of the brain as participants engage in tasks …

Controls and Healthy Vasculature Initiative

Background Diseases involving blood, blood vessels, and immune systems are leading causes of death in the United States. Researchers studying these diseases need to compare blood samples from both healthy and sick individuals. Blood samples from healthy people are also used to establish what is normal when developing new tests …

Outcomes and Health Care Resource Utilization in Pediatric Congenital Heart Disease Patients Undergoing Non-Cardiac Procedures

The incidence of moderate to severe congenital heart disease (CHD) in the United States is estimated to be 6 per 1000 live-born full term infants. Recent advances in pediatric cardiology, surgery and critical care have significantly improved the survival rates of patients with CHD leading to an increase in prevalence …

Whole Exome and Whole Genome Sequencing for Genotyping of Inherited and Congenital Eye Conditions

Objective: The objective of this study is to identify genetic causes of inherited eye conditions through whole exome or whole genome sequencing. This includes identifying mutations in known genes or novel genes for recognized conditions, as well as identifying mutations in novel genes for previously uncharacterized genetic conditions involving the …

Natural History Evaluation of Charcot Marie Tooth Disease (CMT) Types CMT1B, CMT2A, CMT4A, CMT4C, and Others

This is an observational longitudinal study to determine the natural history and genotype-phenotype correlations of disease causing mutations in Charcot Marie Tooth disease (CMT) type 1B (CMT1B), 2A (CMT2A), 4A (CMT4A), and 4C (CMT4C). The investigators will also be determine the capability of the newly developed CMT Pediatric Scale (CMT …

Genotype -Phenotype Correlation of PKLR Variants With Pyruvate Kinase, 2,3-Diphosphglycerate and Adenosine Triphosphate Activities in Red Blood Cells of People With Sickle Cell Disease

Background Some people with the same disorder on a genetic level have more complications than others. Researchers want to look for a link between the PKLR gene and sickle cell disease (SCD) symptoms. The PKLR gene helps create a protein, called pyruvate kinase that is essential in normal functioning of …
