NCT01755221
The purpose of this research study is to better understand whether information obtained from a pH probe can help physicians predict whether a patient will respond to the medication that is prescribed for laryngopharyngeal reflux (LPR). The current treatment given to individuals who are diagnosed with LPR is a course of proton pump inhibitor (PPI) medication. Subjects who agree to participate in this study will have a small flexible tube (about the width of a piece of cooked spaghetti) placed in their throat. This tube measures the pH in the throat over a period of 24 hours and helps physicians study the relationship between pH level, LPR symptoms, and the effectiveness of PPI therapy. This study may help physicians find out if certain symptoms or characteristics can help them predict if the PPI medication will be effective for each patient. After probe removal, subjects will receive compensation. They will return to the clinic at their regularly scheduled follow-up visit with the physician, 8 to 12 weeks after starting the PPI medication. At that time, subjects can choose to participate in an optional probe placement.
NCT05811468
This study will compare the performance of Gene Expression Profile (GEP)/ Donor derived cell free deoxyribonucleic acid (dd-cfDNA) tests, to the following tests: Molecular Microscope (MMDx) and histopathology (study of changes in tissues caused by disease) in their ability to diagnose (exactly identify) various types of injury within the transplanted kidney.
NCT02224677
This study is a multi-center, longitudinal cohort study of 125 infants with craniofacial microsomia (CFM) and 100 infants without craniofacial anomalies. Participants will undergo a series of evaluations between 0-3 years of age to comprehensively evaluate the developmental status of infants and toddlers with CFM. This research design will also explore specific pathways by which CFM may lead to certain outcomes. Specifically, the study explores (1) the longitudinal relations between facial asymmetry and emotion-related facial movements and socialization; and (2) associations among ear malformations, hearing and speech deficits and cognitive outcomes. Results of this research will ultimately lead to future investigations that assess new interventions and corresponding changes in current standards of care for children with CFM.
