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.
Epidurally administered Depodur provides equal or superior analgesia as an epidural infusion of fentanyl for the first 48 hours after a cesarean section.
The purpose of this research study is to evaluate a patient education program for chronic wound care. The wound care nurse practitioner (NP) at the Ann Arbor VAMC will use a wound self-management "after-care summary" with approximately half of her patients. This study will examine whether using this patient education tool for self-management of wound care results in improved patient outcomes.
To allow surgeons to obtain clinical experience on the postoperative uncorrected and best distance corrected visual acuities (UCVA and BDCVA) and corneal and refractive cylinder of the AcrySof Toric IOL.
This study is an international, multi-center, randomized, double-blind, placebo-controlled study in subjects with PAH who are currently receiving approved therapy for their PAH (i.e., endothelin receptor antagonist and/or phosphodiesterase-5 inhibitor)or as a monotherapy treatment. Study visits will occur at 4 week intervals for 12 weeks with the key measure of efficacy being the 6-minute walk test. Study procedures include routine blood tests, medical history, physical exams, disease evaluation, and exercise tests. At the end of the first 12-weeks, the patient will be un-blinded. Patients will continue with another 12-Week open label portion with visits occuring at 4-week intervals. Patients who complete all assessments for 24-weeks will also be eligible to enter a 36 month open-label, extension phase study (FREEDOM - EXT).
The purpose of this study is to use magnetic resonance spectroscopy (MRS) and diffusion tensor imaging (DTI) to assess for traumatic brain injury and determine if there is any correlation of these findings to clinical outcome. MR spectroscopy using 2D-CSI (a multi voxel technique) of the corpus callosum, basal ganglia, lobar white matter and brainstem may reveal areas of injury and quantification of the metabolites from these areas may be used to correlate with imaging findings and clinical evaluation. White matter disruption in these areas is commonly seen after TBI, caused by diffuse axonal injury. It has been implicated in the long term outcomes in these patients, but has been difficult to assess by standard radiologic studies. By the use of DTI it may be possible to demonstrate damaged white matter tracts which could be helpful in the evaluation of traumatic brain injury. Most TBI subjects have injuries that involved torque to the brain. This results in a shearing injury to the long white matter tracts, which has been hypothesized to be related to cognitive outcome. Also, to demonstrate that MRS and DTI prove valuable in predicting outcome in patients of moderate brain trauma by conducting progressive studies acutely (within 24 hours) and long term (4-6 weeks). Most patients will most likely be followed clinically for over a year, and, if clinical indicated, farther scanning can be done at a later date. By comparing fraction anisotropy, ADC values, and metabolic ratios by the use of DTI and MRS in the adult and pediatric populations, may help to assess differences in recovery. Lastly, a comparison between the two groups in changes in brain metabolism and/or white matter tract disruption/re-connection after TBI with and/or without links to outcome can be done.
The objective of the study is to compare the visual outcomes of three aspheric monofocal intraocular lenses after cataract surgery - ACRYSOF® IQ, Tecnis® and Akreos® MI60.
Maternal cardiac disease complicates approximately 2 percent of pregnancies and is the leading cause of non-obstetrical maternal death. Evaluating cardiac function and dysfunction is a complex process requiring skilled clinicians and technology such as ECG, long-term monitoring, and echocardiography. A fast, easily obtained blood test for B-type natriuretic peptide (BNP) has been developed that can give evidence for heart muscle stretch and dysfunction among adults with suspected congestive heart failure. Preliminary experience indicates that ventricular dysfunction among OB patients with a history of heart disease can be detected with this serum assay. A prospective cohort design consisting of two groups of pregnant patients; one with a history of cardiac disease and one without, will be followed over the course of the pregnancies and cardiac function will be measured using echocardiography and serum BNP. It is hoped that the blood test for BNP will be a reliable way to help evaluate OB patients with suspected abnormal heart function.
This is a prospective case-control study to evaluate women who are pregnant and take antihypertensive medication for fetal hemodynamics (middle cerebral artery peak systolic flow and umbilical artery Doppler systolic to diastolic ratio) compared to a control group of pregnant women not taking these kinds of medications. The hypothesis is that the investigators expect to observe little to no difference in the comparison between the medication group and the control group.
