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.
Depression is a wide spread illness. Depression contributes most significantly to national health care costs. While the number and types of treatments used for depression have expanded over the years, even with an increased range of options, the response rate, defined as the number of subjects who have a 50% reduction in depressive symptoms, is estimated to be around 65%. This randomized clinical trial will examine the frequency of treatment with ketamine in patients with treatment-resistant depression TRD without psychosis. It will compare two modes of the ketamine treatment; every other day ketamine, versus two active and four placebo treatments over the period of 12 days.
The purpose of this study is to determine whether a protein called TREM-1 can be used to differentiate viral and bacterial pneumonias in children who are on ventilator support. We propose that the level of TREM-1 will be significantly elevated in the lung fluid of children with bacterial pneumonia and viral with co-existing bacterial pneumonia than in children with pure viral pneumonia.
Subjects with newly diagnosed brain tumors who undergo surgical resection and whose pathology in the operating room shows a high grade glioma will be eligible. During a screening visit, the study will be discussed, inform consent discussed and signed, a medical history will be taken and a physical examination and laboratory tests will be performed. If these tests are all within acceptable ranges, the subject will be considered for inclusion on this treatment protocol. If the results of any tests are extremely different from normal expected values, she/he may not be able to participate. Prior to surgery, the subject will have a contrast enhanced MRI and MRS. The neurosurgeon will attempt to remove the majority of the tumor in the operating room and will send a portion of the specimen removed to the pathologist immediately. This is called a "frozen section". If the pathologist believes that the tumor is a high-grade malignant brain tumor, then the surgeon will place up to 8 dime-sized chemotherapy wafers in the tumor cavity of the brain. The remainder of the tumor specimen will be given to the pathologist to review more closely in the laboratory. If the frozen section does not show that the tumor is a high-grade malignant brain tumor, the subject will not receive the Gliadel wafers and will be removed from the study. The surgeon will then discuss with the subject the appropriate treatment options for the disease he or she has. During recovery in the hospital, another contrast enhanced MRI will be performed within the first 72 hours after surgery. This is a standard of care for patients who are not involved on this protocol as well. The subject will have another contrast enhanced MRI and MRS performed at the 21st Day after his or her surgery. After Day 21, He or she may begin other forms of treatment. The last contrast enhanced MRI and MRS assessment will be performed 12 weeks after the surgery and the implantation of the Gliadel wafers. Further MRI and MRS may be performed subsequently at the discretion of the doctor. Throughout the course of treatment, clinical data will be collected.
Test hypothesis that milk can raise blood sugars as well as orange juice or glucose tablets without raising blood sugars too much the way that orange juice or glucose tablets sometimes do.
Assess the effect of nepicastat in the treatment of in Post Traumatic Stress Disorder (PTSD) in conflict or combat zone experienced veterans, in comparison to placebo.
The purpose of this study is to determine how many patients with Parkinson's disease have compulsive behaviors, and what types of behaviors they have. This study will also determine if acamprosate can be used to treat compulsive behaviors in Parkinson's disease patients.
The EverOn™ system developed by EarlySense, Ltd., the sponsor of this study, is intended to assist hospitals to better address and improve recognition and response to changes in a patient's condition. The system, monitors the patient while in bed consists of a contact-free sensor that is placed under the bed mattress and identifies respiratory and heart rates, degree of patient's movement or agitation while in bed as well as patient's actual exit out of the bed. The EverOn system does not require a physical contact with the patient, eliminating the need for any direct contact electrodes, leads, cuffs or nasal cannulae.
The long-term goal of this study is to learn if Zoledronic Acid can prevent or reduce pain in sickle cell disease. The goal of this study is to learn about the safety of Zoledronic Acid in persons with sickle cell disease who experience chronic pain requiring medical treatment or use of narcotics.
The purpose of this study is to compare the features that the pathologist sees, when examining a lung tumor under the microscope, to the way that the tumor appears on the computed tomography (CT) scan. Features of the tumor may include abnormal blood vessels and areas in which tumor cells are dying. The samples that are taken during the needle biopsy contain information from one small part of the tumor. The investigators believe that they can show where in the tumor the samples came from, based on the CT scans during the biopsy procedure. If the investigators can accurately determine where in the tumor their samples came from, they can compare the features of that part of the tumor, as seen on the CT images, to the features of that part of the tumor as seen under the microscope. This research study also will give the investigators an idea of how much the biopsy samples are distorted in the process of preparing them for examination under the microscope.
The purpose of this study is to analyze the gene expression patterns associated with various microenvironmental stresses in tumors to understand their roles in tumor progression and treatment responses. To achieve this goal, we will perform gene expression analysis of the tumor samples collected from an IRB-approved study (IRB #: 4516-05-2R2) International Phase III Study of Chemoradiotherapy versus Chemoradiotherapy Plus Hyperthermia for Locally Advanced Cervical Cancer directed by Dr. Mark Dewhirst. We will correlate the gene expression signatures of different microenvironmental stresses with the measured physiological parameters to understand their role in tumor progression, treatment response and clinical outcomes.
