Clinical Trials

This phase II trial studies how well xisomab 3G3 works in preventing catheter-associated blood clots (thrombosis) in patients with cancer receiving chemotherapy. Many patients with cancer develop blood clots from their catheters and can have pain, swelling, and other symptoms.

The goal of this clinical trial is to compare the effectiveness of unseparated whole blood (referred to as Low-Titer Group O Whole Blood) and the separate components of whole blood (including red cells, plasma, platelets, and cryoprecipitate) in critically injured patients who require large-volume blood transfusions.

This study will test two different platelet transfusion strategies, based on two different platelet counts thresholds.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

This study aims to see if a blood test can predict rejection and take the place of biopsies. The test shows how much donor DNA is in a recipient s blood. Adults 18 years and older who are on the lung or heart transplant waitlist are eligible.

The purpose of this study is to evaluate the feasibility and preliminary efficacy of the Promoting Resilience in Stress Management (PRISM) intervention in patients with adult congenital heart disease.

Participants from this study will be recruited mainly from Emory Healthcare-associated hospitals, the Emory Heart Disease Center for Prevention, and Emory Healthcare outpatient cardiology clinics. Participants will have physical exams, blood tests, stress tests, exercise tests, surveys, questionnaires, and images taken of their hearts and blood vessels. They will be asked to take home devices to monitor their autonomic function, sleep and to track their mood, stress level, and symptoms for one week. Data and specimens will be saved for future research.

Cardiopulmonary bypass during cardiac surgery provides blood flow to the body during surgery but has adverse effects on different organs. Blood flow during cardiopulmonary bypass may be pulsatile or non-pulsatile, which may impact normal organ function after surgery. The study will collect data on the type of cardiopulmonary bypass used during surgery and organ function to determine if there is an association between the type of bypass and organ function.

This study will identify and test the physiological effects of several sedentary behavior interruption strategies and explore the feasibility (i.e., likelihood of an individual performing the requested activities) of those strategies to inform the development of public policy surrounding sedentary behavior interruption. Long-term, the findings of this study will inform a large clinical trial that can test whether sedentary behavior reduction can decrease cardiovascular disease risk.

The researchers propose that exercise and weight loss interventions (bariatric surgery) will restore adipose tissue homeostasis, reduce GSL-loaded adiposomes, and subsequently alleviate vascular risk in OB-T2D patients. The investigators will test the hypotheses by pursuing the following aims: aim 1: Investigate the role of GSL-rich adiposomes in the pathogenesis of endothelial dysfunction in OB-T2D adults; aim 2: Test the effectiveness of exercise training in reducing adiposome-mediated effects on vascular function; and aim 3: Examine changes in adiposome/caveolae axis following metabolic surgery and their association with vascular function.
