Clinical Trials

Are you a healthy adult? In this clinical trial, researchers are trying to improve the quality of heart CT scans by using new methods to create the images. Researchers will take normal CT images of the heart and compare those images to super high-resolution images made with a super-computer. Healthy adults aged 18 years or older may be able to participate. The study is taking place at the NIH Clinical Center in Bethesda, Maryland.

Are you at least 18 years old and scheduled for a CT of the chest, abdomen, and pelvis? In this study, researchers want to learn if new CT imaging methods with less radiation make images that are similar to traditional ways. If you are at least 18 and your doctor has said you need a CT scan of the chest, abdomen, or pelvis, you may be able to participate. This study is taking place at the National Institutes of Health Clinical Center in Bethesda, Maryland.

DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 24-27 6/7 weeks gestation undergoing extubation from mechanical ventilation, whether (I) Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) (C) compared with Non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), will reduce the incidence of (O) extubation failure within (T) 5 days (120 hours) of extubation.

The goal of the study is to look at the relationship between how individuals with Sarcoidosis take the sarcoidosis medicines and how it affects the disease, to evaluate any factors that may make individuals not want to take the medicines, and to develop and refine ways to help support individuals with Sarcoidosis especially when it comes to the medicines. The overall hypothesis is higher medication adherence will be associated with better clinical outcomes in sarcoidosis. The investigators will enroll 150 patients with biopsy proven pulmonary sarcoidosis for at least one year who are on any oral treatment regimen for at least six months into a 12-month longitudinal study.

Are you a woman with coronary microvascular dysfunction? In this clinical trial, researchers are studying coronary microvascular dysfunction, which occurs when there are problems in the small blood vessels in the heart. It frequently causes chest pain and is more common in women. The researchers want to learn how daily life and mental stress affect the heart. You may be able to participate if you are at least 45 years old, have gone through menopause, and are willing to undergo tests to measure your stress level. The study is taking place at locations in Atlanta, Georgia.

The purpose of this study is to determine the occurrence of scarring of the heart (cardiac fibrosis) and inflammation in those with perinatally acquired Human Immunodeficiency Virus (HIV) infection compared to people not infected with HIV. The information learned from this research may help the investigator to better understand the link between cardiac fibrosis and cardiac dysfunction and inflammation in those with perinatally acquired HIV infection compared to the uninfected.

Are you an adult who gets little exercise and sits a lot every day? If you sit for more than 8 hours a day and exercise less than 90 minutes per week, this study may interest you. Researchers want to see if walking or standing breaks during long sitting periods can make your heart healthier. To take part in this study, you must be 36 to 55 years old. You also should be able to walk four blocks and go up two flights of stairs. The study is taking place in Chapel Hill, North Carolina.

The primary purpose of this study is to investigate whether a voice-based platform is better for delivering an electronic health intervention to older adults than a text/typing-based platform. We have an evidence-based electronic health intervention (Elder Tree, ET) that has been shown to improve quality of life, physical and socio-emotional health outcomes for older adults with multiple chronic conditions when delivered via a text/typing-based system. The current project would test whether such patients would benefit even more if ET were delivered via a voice-based system (vs. the text-based system) because they would use it more consistently. ET is an existing intervention providing tools, motivation, and support on a computer platform to help older adults manage their health.

The objective of this study is to investigate the mechanisms of respiratory functional and respiratory motor responses to the scES as an important step toward the long-term goal of developing effective evidence-based rehabilitation strategies for patients with SCI. The central hypothesis is that scES raises the excitability of motor networks for respiration resulting in amplified use-dependent neural plasticity in response to the respiratory training. The rationale for the proposed study is to justify the development of a new direction in respiratory rehabilitation by using respiratory training in combination with electrical spinal cord stimulation.

The purpose of this study is to see if adding a drug called Regadenoson to the EVLP circulation reservoir during perfusion of marginal donor lungs will help increase the likelihood that the donor lungs will become usable for transplantation.
