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.

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.

In this study, quantitative characterization of plaque using coronary computed tomographic angiography (CTA) will be used to determine if women who were treated with intensive medical therapy have a greater reduction in the amount and type of cholesterol plaque compared to women receiving usual care and if this results in beneficial changes in clinical symptoms. The study will provide an understanding of how intensive medical therapy works in providing clinical benefit in women with nonobstructive plaque.

Currently, there are 3.5 million breast cancer survivors in the United States and this number is expected to increase dramatically. The proposed research will examine whether a novel exercise intervention for breast cancer patients who are undergoing chemotherapy protects against cardiovascular dysfunction. Findings may have implications for cardiovascular disease prevention in this population.
