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.
To explore the effects of corticosteroid therapy on pulmonary fibrosis and potentially pneumothorax in patients with mild PCP (pO2 >70mmHg) combined with the standard of care treatment of antibiotic therapy.
Primary Objective: 1. Evaluate the efficacy of letrozole to increase the duration of progression-free survival (defined as time to earliest occurrence of local or distant recurrence or clinically significant elevation in CA-125) when used as adjuvant treatment after completion of primary surgery and first line platinum containing chemotherapy in patients with optimally debulked (< 1 cm residual disease) stage IIA-IIIC ovarian, fallopian tube, or primary peritoneal cancer. Secondary Objective: 1. Observe the incidence of local and distant recurrences.
The hypothesis is that prelemniscal radiation (RaPRL) deep brain stimulation (DBS) is more effective for axial (head/neck/voice) tremor, and perhaps, appendicular tremor control in essential tremor patients.
Assessment of segmental spine motion has been and continues to be, a difficult clinical problem. Errors of up to 10 degrees for simple measurements of flexion, extension and side bending have been recorded using conventional radiographs (xrays.) These errors are usually associated with the inability to acquire three-dimensional positions and inaccurate reference points. It has, therefore, been extremely difficult to measure small changes in vertebral alignment, which may prove to be an early, clinically significant, indicator of potential problems. Radiostereometric Analysis, or RSA, is an accurate in vivo measurement technique using two simultaneous radiographs. It provides researchers with three dimensional motion analyses to look not only at routine flexion/extension, but also other rotational and translational changes. The measurement accuracy offered by this technique far exceeds the manual techniques currently used. The purpose of this study is to assess the amount of motion in the lumbar spine in patients with the AST Stabilimax BAR. The AST Stabilimax BAR is designed to allow for motion in the spine while providing the necessary stability to the spinal segment. The amount and degree of this motion is currently unknown clinically. By using tantalum bead markers placed in the spine at the time of the surgery, RSA analysis can determine the amount and degree of motion of the implanted construct. Two questions will be examined with this data: 1) what is the amount of sagittal and coronal plane motion that occurs in vivo with the AST Stabilimax BAR system? and 2) will this change over the 2 year time frame for this study?
Ezetimibe is a drug which inhibits the absorption of both dietary and biliary cholesterol in the small intestine. Ezetimibe has been approved for use in humans to lower serum cholesterol. The primary aim of this study is to determine if ezetimibe normalizes resting and residual volume in patients with chronic acalculous cholecystitis.
The purpose of this study is to compare the effects of nebulized formoterol fumarate (Perforomist) to dry-powder inhaler formoterol fumarate (Foradil). Perforomist is a solution that is made into very fine spray (using a nebulizer) that is then breathed in over 10-15 minutes. Foradil is taken in a single quick, deep inhalation.
The study will compare effectiveness of intravenous magnesium sulfate to that of intravenous metoclopramide (Reglan®) for acute headache in pregnant women. We will randomize pregnant women who present to our emergency department with chief complaint of headache to magnesium sulfate 2 grams intravenously or metoclopramide 10 mg intravenously; both groups will receive acetaminophen (Tylenol®) 1 gram orally and normal saline 1 liter intravenously. Headaches are common during pregnancy, related to hormonal changes, altered sleep patterns and psychosocial stressors. Common medications for headache such as non-steroidal antiinflammatories or triptans are typically avoided during pregnancy due to concern for fetal effects. Women, and their physicians, are often uncertain regarding available medication options with justifiable safety profiles during pregnancy.
The goal of this proposal is to test the performance of a novel optical imaging system for real-time quantitative imaging of brain function through multiple hemodynamic measures during neurosurgery. This pilot study encompasses two sub-aims: - Evaluate the ability of laser speckle contrast imaging to image cerebral blood flow (CBF) intraoperatively. We will image the changes in CBF in response to somatosensory stimulation. (5 patients). - Simultaneously image hemoglobin oxygenation, blood volume, blood flow, and cerebral metabolic rate of oxygen (CMRO2) changes during somatosensory stimulation using a combined laser speckle and multi-wavelength reflectance imaging system. (5 patients).
Failure to wean from mechanical ventilation (failure to get the patients off the breathing machine) is associated with prolonged stay in the intensive care unit and increased risk of death. Some patients have difficulty successfully getting off the ventilator and breathing on their own. Usually this difficulty is due to lung problems. But sometimes it is due to heart problems, or heart failure. To improve a patient's chances of successfully getting off the ventilator early, it is helpful to the doctors to know if patient has heart failure and to measure how severe. With the new monitoring system being studied here, doctors may be able to detect and measure heart failure more easily. A new monitor (Vigileo TM) that is connected with a specific cable (Flo-TracTM) to a catheter that is inside the patient's artery (arterial line) has lately been developed. This monitor can estimate the amount of blood that the heart is pumping per minute, known as cardiac output. The heart is supposed to pump blood harder when a patient is being weaned from the breathing machine. With the above mentioned monitor, we hope to detect those patients whose hearts are weak and are not pumping as hard as they should.
Von Willebrand disease is an inherited bleeding disorder that impacts the blood's ability to clot properly. Von Willebrand disease is cause by the lack or not working substance in the blood known as Von Willebrand factor. Current therapy for Von Willebrand disease includes desmopressin acetate (DDAVP) and /or VWF/FVIII concentrates. Patients with severe Von Willebrand disease face a lifetime of weekly treatments and mounting medical bills. Gene therapy could help these patients improve their quality of life by providing the missing factors necessary for the blood's ability to clot properly. The gene transfer options being studied include naked DNA, viral gene transfer vectors encoding Von Willebrand factor transgenes, and ex vivo cell therapy. The latter involves transplantation of the patient's own cells modified with a corrected copy of the defective gene. Human blood outgrowth endothelial cells (BOEC) display all the properties needed for successful ex vivo cell therapy. We plan to obtain blood samples from normal research subjects and patients with Von Willebrand Disease in order to isolate blood outgrowth endothelial cells (BOEC) from peripheral blood, and develop a ex vivo gene therapy for Von Willebrand Disease.
