NCT00552955
This study will examine the effect of fasting on lymphangioleiomyomas abdominal tumors formed from enlarged lymph nodes containing lymphatic fluid. Previous studies have determined that these tumors increase in size in the evening, but this result could stem from the fact that previous study participants were tested after eating lunch. The purpose of the study is to help researchers understand the factors that produce changes in size of lymphangioleiomyomas, as well as to improve the ability of medical professionals to diagnose lymphangioleiomyomas and avoid confusing these tumors with other malignant tumors. Volunteers must be women who are at least 18 years of age and who have been diagnosed with lymphangioleiomyomas in the abdominal or pelvic areas. Candidates who have had lung or kidney transplants or who have type 1 diabetes will be excluded. Candidates will be screened with a physical examination and medical history. During the study, participants will be admitted to a National Institutes of Health clinical center for three days to undergo a number of tests. Tests will include routine blood and urine tests, and electrocardiogram, research blood testing, and abdominal and pelvic ultrasounds....

NCT01983293
The purpose of this study is to analyze the effect of left ventricular lead pacing location in the non-left bundle branch block (non-LBBB) heart failure patient population. The left ventricular lead pacing location will be guided by either the pacing site with the largest amount of dyssynchrony as measured by the LV electrical delay (QLV) or the physician's standard of care implant approach.
