There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to obtain observational data allowing for the preliminary assessment of the utility of a noninvasive physiologic monitor for monitoring of patients with congestive heart failure.
This study will create a patient data registry to collect and analyze information on technology usage and outcomes among patients receiving a broad range of relatively new radiation treatments that have become standards of care in our practice. Review of this information will serve as a basis for development of better patient management plans, to inform decisions about acquisition of new technologies, to provide information about quality in our care delivery, and to create a database that will securely warehouse ongoing information about what treatments the patients we serve need most and the challenges they face in the treatment process. The information gathered is likely to not only improve our services at the University of Maryland and its community sites but to advance medical science and enhance the quality of care for cancer patients.
The investigators hypothesis is that a 22 gauge needle can yield core tissue, obviating the need to use the 19 gauge needle for core tissue procurement.
Patients will be randomized (like the flip of a coin) to receive Exparel and a nerve block, standard of care for this procedure, or Exparel alone for pain management after surgery. They will also be asked to complete questionnaires before surgery, during their stay at the hospital after surgery, then at 3 months, 6 months and 12 months after surgery to assess pain and/or function levels, as well as the amount of pain medicine patients have used after surgery. Patients' leg strength will be measured immediately after surgery and again at 3, 6 and 12 months after surgery.
This is a research study to assess whether an oral medication can benefit some patients being treated for peripheral pulmonary stenosis (PPS), which is narrowing of the blood vessels that send blood to the lungs (pulmonary arteries). In the cardiac catheterization laboratory, the investigators treat PPS by dilating the narrowed segments of pulmonary arteries using balloon catheters. Sometimes the investigators also place stents which are mesh tubes that help keep the narrowed vessel open. Some stents suffer from in-growth of tissue into the stents which causes recurrent obstructions inside the stent (i.e. making the opening inside the mesh tube narrow again), so called in-stent stenosis (ISS). The purpose of this study is to use a medication that is approved for use in children (for a different purpose) to decrease the amount of cell ingrowth inside the stents (i.e. decrease the problematic in-stent stenosis). The medication is called rapamycin, also known as sirolimus (trade name Rapamune). It has antiproliferative properties which means that it slows down cell division which the investigators believe cause the recurrent narrowing inside stents. Rapamycin is a medicine that can be taken by mouth as a liquid or pill or via a feeding tube. There will still be a need for interventions in the catheterization laboratory but the investigators hope that by taking this medicine some children would need fewer catheterizations in the future. Our early experiences with a few patients who have been treated with rapamycin due to in-stent stenosis in the pulmonary arteries suggest that it may be helpful. In this study, patients and families who are interested in possibly trying this new approach will be randomized to sirolimus or no sirolimus. The investigators will compare the developement of ISS over time between these groups, in a hope to learn whether oral sirolimus reduces ISS development.
This study is designed to evaluate if Vasculera, a marketed medical food product, will improve the rate and extent of healing of diabetic ulcers.
Analyis of the Glutathione Cycle in Children with Rett Syndrome
The purpose of this study is to reduce, by using the ultrasound guided technique, the minor surgical procedures that might be required to deliver fluids into the blood of critically ill patients simply because the patients' veins cannot be located through the manual technique.
This study aims to look if use of goggle balloon can help to complete colonoscopy in patients with very redundant colons.
The purpose of this study is to learn if an experimental treatment can help thinking ability, and memory in Veterans with mild or moderate traumatic brain injury (mTBI), and post-traumatic stress disorder (PTSD). The experimental treatment is called transcranial, light-emitting diode (LEDs) therapy,and uses groups of LEDs mounted inside a helmet. The helmet is worn on the head, and the LEDs shine painless light on the sides, middle and front of the head through the scalp. The participants receive a series of LED treatments which take place as outpatient visits at the VA Boston Healthcare System, Jamaica Plain Campus. The LEDs contain near-infrared diodes. The FDA considers the LED device used here, to be a non-significant risk device. The LEDs do not produce heat.
