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 goal of this research is to use Helium-3 MRI to see the changes in airflow of the lungs at different times of an attack. These three stages are immediately after the attack, 1 month later and 4-6 months later.
This research proposal has two main objectives. The first is to increase understanding of the underlying physiological interactions that occur between the cardiovascular, pulmonary, and ANS during transition between positive pressure mechanical ventilation (MV) and spontaneous breathing. The second is to determine if heart rate variability, (HRV) a reflection of autonomic nervous system (ANS) activity, and autonomic information flow (AIF), a set of nonlinear measures derived from HRV, both measured in the intensive care unit (ICU) can predict patient outcomes including successful weaning and in-hospital recovery time after an episode of cardiopulmonary compromise requiring MV. Hypothesis 1. Transitions between mechanically supported ventilation and spontaneous breathing will disturb cardiovascular synchrony, altering the relationship of HRV, AIF, respiratory rate, and blood pressure; Hypothesis 2. More normal HRV and AIF values, measured during baseline MV and sedation awakening (a period immediately prior to SBT when sedative medications are discontinued) will be associated with easier weaning, and shorter intensive care unit (ICU) and hospital lengths of stay; more abnormal measurements will be associated with longer lengths of stay; Hypothesis 3. AIF is a more sensitive predictor of successful weaning from MV than HRV.
Currently, large oral doses of phosphate and 1,25(OH)2D (calcitriol) are the standard treatment of patients with familial hypophosphatemic rickets (XLH). While this therapy is effective in healing the rickets, it is often limited by development of complications due to the high dose of medications required to achieve cure. Among them are the development of calcifications in the kidneys and secondary hyperparathyroidism (HPT) which in some patients may cause complications like high blood calcium level, high blood pressure and damage to the kidney. A drug to treat secondary hyperparathyroidism was just developed. In a short term study we found that it might help the treatment of XLH, by allowing the use of lower doses of the both phosphate and calcitriol. In the present study we will learn if indeed the addition of this new medicine (Cinacalcet) to the long-term treatment will allow the use of lower doses of both phosphate and calcitriol and consequently lower the risk of complications.
This is a clinical trial for women with newly diagnosed ovarian cancer. The purpose of this study is to determine if the addition of a drug called azacitidine (Vidaza®)when added to carboplatin and paclitaxel will change the genetic material of the tumor so that the chemotherapy drugs work better. The study will also determine what the maximum tolerated dose of azacitidine that may be safely used in combination with carboplatin and paclitaxel.
This is a study to evaluate the cause of chronic sinus disease. Oral steroids have long been used in the treatment of inflammatory conditions including chronic sinusitis, asthma, and arthritis. However, it is not well known exactly which patients will benefit from steroids when used in the treatment of chronic sinusitis. For some doctors, it is common practice to use these medications prior to planned sinus surgery, to lessen the inflammation and possibly help the healing process. Other doctors feel oral steroids may not be helpful in this way, and there is no conclusive data as to whether this practice has a long term benefit.
Surgeons are the individuals who will operate on a patient if it is determined to be necessary after they present with abdominal pain. For that reason, the investigators want to study if giving a medicine (morphine) to children presenting to the ED with abdominal pain will alleviate pain without changing the patient's physical exam and the subsequent surgeon's decision. The investigators also will record any side effects of morphine, any associated surgical complications, and to identify the ultimate diagnosis.
The purpose of this study is to collect information in order to identify people who have asthma and who may be good candidates to participate in one of the future asthma studies to be conducted at The Ohio State University Asthma Clinical Research Center.
The purpose of this study is to determine if there is an effect on the eye pressure from extreme weight loss by bariatric procedures. The hypothesis is that excess fat in the orbit of the eye compresses on the outflow system, which causes an elevated eye pressure. This can have many consequences, including the risk for glaucoma. We hope to establish if there is an effect between eye pressure and weight.
The purpose of this study is to find out what effects, good and/or bad; rituximab, ifosfamide, carboplatin and etoposide (RICE) followed by gallium nitrate, rituximab and dexamethasone (GARD) have on diffuse large B cell lymphoma. This research is being done to try to find a more effective treatment for this type of cancer. We want to know whether treatment with rituximab, ifosfamide, carboplatin and etoposide (RICE) then followed by gallium nitrate, rituximab and dexamethasone (GARD) will improve survival. Rituximab, ifosfamide, carboplatin and etoposide (RICE) are part of the usual treatment for diffuse large B-cell lymphoma. Gallium nitrate, rituximab and dexamethasone (GARD) in lymphoma is experimental.
Sirolimus can be safely switched as early as 90 days after liver transplantation with excellent tolerability and amelioration of the calcineurin inhibitor toxicity that initiated the switch.
