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 evaluate the effect of Pylera when given twice a day. Pylera approved treatment schedule is 3 pills taken 4 times daily, in addition to omeprazole given twice daily. In this trial, subjects with confirmed Helicobacter Pylori infection will receive Pylera treatment and omeprazole twice daily.
This research is being done to find out the best way to give narcotics for pain relief in adults with sickle cell disease and painful crisis. This study is a comparison of two ways of giving narcotics. The first way is what occurs now in the Emergency Acute Care Unit (EACU) where patients are given a single intravenous (iv) dose of a narcotic which is repeated by the nurse as needed to control the pain. The second way is to provide a single iv dose of narcotic and then allow the patient to push a button and receive one or more additional doses of narcotic when he/she thinks it is needed. Our hypothesis is that PCA will be a more effective way of controlling pain.
A 12-week, multicenter, randomized, double-blind, placebo-controlled phase IV study. Approximately 200 subjects will be enrolled, half will receive active drug (donepezil hydrochloride) and half will receive matching placebo at approximately 50 research sites within the US, the European Union, South Africa and Australia. Eligible subjects will reside at home, in an assisted living facility, or nursing homes age and will be 50 years or older, with a diagnosis of Alzheimer's disease in the severe stage. All subjects must start with 5mg a day (one 5 mg tablet of donepezil HCL or matching placebo). Dose will be increased to 10 mg a day (two tablets of 5 mg donepezil HCL or matching placebo) after 4 weeks. Dose may be decreased based on side effects. The primary efficacy measure will be the Cornell Scale for Depression in Dementia (CSDD). Secondary measures will include Functional Assessment Staging (FAST), Mini-Mental State Examination (MMSE), NPI-10 (Neuropsychiatric Inventory), DEMQOL Proxy ( Quality of Life). Blood levels of cytokines and safety will also be assessed.
Using phase contrast MR Angiography with NOVA® Software, this study intends to identify,evaluate and map intracranial aneurysm development as well as develope a predicator for future morphological changes of aneurysms and possible risk of future rupture.
The restoration of normal blood flow following a period of ischemia may result in ischemia / reperfusion injury (I/RI), which is characterized by inflammation and oxidative damage to tissues. Varying degrees of I/RI occur upon reperfusion of a donor heart after cold storage. Medications containing antibodies against immune cells have been used for many years as powerful immunosuppressants. These medications, called polyclonal antibody preparations, are generally only used immediately following transplantation and/or to treat rejection. At our institution, one such antibody preparation (Thymoglobulin) is used in most pediatric heart transplant recipients for 3-5 days immediately after transplantation. Because standard immunosuppressive medications (called calcineurin inhibitors) are toxic to the kidneys, the use of Thymoglobulin allows us to delay the initiation of calcineurin inhibitors until the kidneys of completely recovered from the shock of the transplant surgery. We hypothesize that Thymoglobulin may be beneficial in reducing the damage caused by I/RI. Thus, the present study seeks to evaluate the effectiveness of an intra-operative dose of Thymoglobulin (in addition to the standard doses post-operatively) at reducing the effects of I/RI. The study will be a double-bind placebo-controlled trial involving 20 subjects. Biologic markers for I/RI will be assessed at periodic intervals for six months post-transplantation. Subjects receiving intra-operative doses of Thymoglobulin will be compared to the controls in order to assess the effectiveness of intra-operative Thymoglobulin in ameliorating the effects of I/RI.
Joint National Committee 7 (JNC-7) defines resistant hypertension as a persistent elevation of blood pressure (BP) above goal - ≥ 140/90 mm Hg for the general hypertensive population or ≥ 130/80 mm Hg for persons with diabetes mellitus or chronic kidney disease - for at least three months despite treatment with three or more optimally dosed antihypertensive agents, including a diuretic. The exact prevalence of resistant hypertension is uncertain but may include 5-20% of hypertensive persons in primary care settings and 15-35% of the older, higher cardiovascular risk hypertensive patients incorporated into recent clinical trials of antihypertensive therapy. Observational studies demonstrate that patients with resistant hypertension experience a higher rate of cardiovascular and renal target organ damage such as left ventricular hypertrophy, microalbuminuria, and renal insufficiency and more cardiovascular disease (CVD) events than patients whose hypertension is well-controlled. Additionally, resistant hypertension patients may be subjected to the considerable expense of multiple office visits, diagnostic testing for secondary causes of hypertension, and referral to hypertension specialists. Because multiple factors can contribute to resistant hypertension, an explicit, sequential approach to evaluation and management is essential to optimize blood pressure, reduce cardiorenal morbidity and mortality, and avoid unnecessary expense. A number of observational studies have suggested the potential efficacy of both spironolactone and amiloride when added to a 3 drug antihypertensive regimen, but to date no randomized study has directly compared the two agents. The goal of this study is to determine whether spironolactone or amiloride is the more effective fourth agent to add to a three drug regimen in patients with resistant hypertension.
This study compares the fill of bone graft sites in the knee. It is hypothesized that harvest sites, voids, and defects caused by trauma that are treated with the OsseoFit™ Porous Tissue Matrix™ device will achieve a better fill grade than those treated with the conventional method.
The purpose of this study is to evaluate the safety and efficacy of Hydrophilic Acrylic Intraocular Lens after cataract surgery
The purpose of this study is to determine if the HemCon Dental Dressing is effective in stopping bleeding during dental surgeries in patients taking anticoagulant medications.
