Filter by:The primary objective is to analyze the safety and efficacy of CD133+ cells, obtained from peripheral blood in the treatment of diabetic patients with critic ischemia in lower limbs. The secondary objectives are: - To determine the safety of the intramuscular administration of CD133+ cells that have been mobilized from peripheral blood. - To determine the CD133+ capacity to increase the re-vascularization at lower limbs in diabetic patients with critic ischemia in the lower limbs. - To evaluate the patient global health condition using the notified results of the SF-36 questionnaires completed by patients
The purpose of this study is to evaluate the use and efficacy of the Encore Linear™ Hip System in a group of 200 patients for whom data has already been collected.
The purpose of this study is to evaluate the use and efficacy of the Encore Foundation Knee System in a group of 200 patients for whom data has already been collected.
The purpose of this study is to compare the survivorship and efficacy of the Encore 3DKnee™ system with that of the Encore MJS™ Knee System in a group of 600 patients for whom data collection is already under way.
The purpose of this pilot study is to conduct research to determine the most effective physical therapy treatment for a condition called shoulder impingement. This condition occurs when tissue in the shoulder is caught between the humerus (arm bone) and the scapula (shoulder blade). This causes pain when one tries to reach overhead or behind the back. Two treatment methods will be used in the study. The first method uses the traditional treatments of hands-on shoulder stretching, shoulder exercise, posture, and education. The second method will use the traditional methods of shoulder treatment in addition to treatment of the cervical spine. It is hypothesized that a group of patients between 40 and 70 years of age with signs and symptoms of shoulder impingement who receive physical therapy to the cervical spine and shoulder will report a higher level of functioning, will report less pain, and will gain more range of motion than a group of patients receiving physical therapy solely to the shoulder.

This 4 arm study in patients with advanced Stage IIIb/IV non-small cell cancer (NSCLC) who failed at least one standard chemotherapy regimen will determine the proportion of patients with progression-free survival at 12 weeks following combination therapy with R1507 and Tarceva or placebo and Tarceva. Patients will be randomized to one of four treatment arms to receive R1507 (9mg/kg iv) or placebo weekly or R1507 (16mg/kg iv) or placebo every 3 weeks. Tarceva (150mg oral daily) will be administered in all treatment arms. Other disease-related endpoints including overall survival, objective response rate, time to response, time to progressive disease and duration of response will also be evaluated. The anticipated time on study treatment is 1-2 years, and the target sample size is <500 individuals.
This non-inferiority study will compare the clinical outcomes of subjects implanted with the Dynesys Spinal System versus the clinical outcomes of subjects implanted with an instrumented posterior lateral spinal fusion.
Background: Delirium and long-term cognitive dysfunction (CD) are important complications of major surgery and intensive care treatment. Delirium is associated with increased mortality and CD has an important impact on mortality, independency, social interactions, and quality of life. Delirium is an important risk factor for the development of long-term CD. Particularly, patients aged 65 or older undergoing cardiac surgery are at a high risk of developing these problems. There are data suggesting that inflammation plays a key role in the development of delirium and possibly CD. It has been shown that n-3 fatty acids modulate the immune response of patients and have beneficial effects in abdominal surgery. Working hypothesis: 1. Administration of n-3 enriched nutrition therapy including will modulate the inflammatory response and improve cognitive function after cardiac surgery. Specific Aims: This project will test the impact of perioperative enteral n-3 fatty acids ProSure, Abbott Nutrition) in elderly patients undergoing elective cardiac surgery. Primary endpoint is CD one week postoperatively. Methods: The investigators will investigate 400 patients aged 65 or older undergoing elective cardiac surgery. Half of these patients will receive supplementary of n-3 fatty acids to modulate the inflammatory response; the other half will receive an isocaloric nutritional supplement without n-3 fatty acids (Ensure Plus, Abbott Nutrition). Otherwise the treatment of the patients will not be influenced by this study. Cognitive function will be assessed preoperatively, 7 days and three months postoperatively. C-reactive protein, IL-6, IL-8, IL-10, S-100B, and neuron specific enolase will be monitored as markers of systemic inflammation and delirium.
This study will test whether transcranial direct current stimulation (TDCS) can be used safely in children with schizophrenia and if it can improve memory and attention span or auditory hallucinations in these children, at least temporarily. TDCS has temporarily improved memory and attention span in healthy adults and a similar method called TMS has relieved auditory hallucinations in adults with schizophrenia. For the TDCS procedure, the child sits in a chair and two soft sponge electrodes are placed on the child s forehead and held in place with a soft wrapping. One sponge electrode is placed on an arm. The electrodes are attached to a stimulator with a wire. Children with schizophrenia who meet the following criteria may be eligible for this study: - Are 10 yrs or older age. - Are participating in NIH protocol 03-M-0035. - Are on a stable medication regimen for at least 6 months. - Have problems with memory and attention span or have auditory hallucinations. Participants are randomly assigned to receive either real or sham TDCS on an inpatient or outpatient basis in 20-minute sessions daily, except weekends, for 10 days. For real TDCS, patients receive stimulation to the front of the brain. For sham stimulation, the children have electrodes placed on the forehead, but no actual stimulation is delivered. In addition to TDCS, patients have the following procedures: - Checks of blood pressure, pulse and breathing rate before, during and right after each stimulation and again 8 hours later. - Electrocardiogram (EKG) and electroencephalogram (EEG) before starting stimulation and after completing the 10 days of TDCS. - Interviews and examinations to check for side effects of TDCS. - Pen-and-paper or computer tests of learning, attention and memory. - At the end of the 10 sessions, children who were in the sham TDCS group are offered the same number of sessions of active TDCS. - Follow-up telephone call 1 month after the end of stimulation to see how the child is doing. - 1- to 2-day outpatient visit 6 months after the stimulation. This visit includes interviews with the parent and the child, rating of the child s psychiatric symptoms, and pen-and-paper or computer tests of thinking, attention and memory.
