Filter by:Stroke (CVA) is the leading cause of death and the leading cause of disability in developed countries as in developing countries (WHO, 2000). In the aftermath of a stroke, patients keep a permanent disability in 75% of cases and only one quarter of them is able to resume work. The post stroke sequelae are sensory-motor and cognitive. According to literature data, 75-83% of patients who survive a stroke learn to walk only 25 to 45% recover use of their upper limb in activities of daily living (Friedman, 1990). The existence of a phase called "plateau" in motor recovery after stroke has been suggested (Colautti, 2001). This would occur beyond the 4 th month and would correspond to a phase where the rehabilitation techniques used in the subacute phase are deemed less effective. Recently, Page (2004) speculated that this plateau phase is rather the consequence of adaptation to the type of patient follow-up training and not that of a limit to the possibilities of recovery. In an observational study on the recovery of upper limb conducted over a period of 4 years, Broeks (2004) showed a possible recovery beyond 16 weeks post stroke. The results of studies on different techniques for rehabilitation of chronic stroke patients tend to confirm the hypothesis of page. Therefore, varying the training parameters (type, intensity, frequency) could improve the functional capabilities of these patients, even at a distance of stroke. Strength training is part of the management of hemiparetic patients. The results of several studies show an improvement in muscle strength and functional ability to walk after a building program isokinetic lower limb (Sharp, 1997). The objective of our project is to evaluate the effectiveness of a building program of isokinetic muscle on the paretic limb motor recovery in hemiparetic patients over 6 months of a stroke.
This study is to evaluate the efficacy of a 2-week course of tolvaptan in improving serum sodium and the excretion of extracellular fluid in liver cirrhotic patients with ascites and hyponatremia
The purpose of this study is to evaluate the hypothesis that advanced hemodynamic monitoring results in an earlier detection of circulatory failure in newborn infants
The purpose of this study is to find out the highest safe dose and examine the side effects and effectiveness of eltrombopag olamine in patients with acute myeloid leukemia (AML) treated with chemotherapy that have not responded to previous therapy or have suffered a relapse
This is a study whose main objective is to evaluate prospectively the proportion of patients with severe xerostomia one year after treatment with tomotherapy for head and neck cancer.
The aim of this study is to increase, by DHA-induced chemosensitization, the activity of anticancer chemotherapy in patients with a metastatic advanced breast cancer, by a nutritional approach with marin-derived PolyUnsaturated Fatty Acids (PUFA).
Background: - Some people with human immunodeficiency virus (HIV) develop problems with thinking and concentration when the virus affects the brain. This is known as mild neurocognitive disorder (MND). Research has shown that some HIV medications do not get through the blood brain barrier very well. P-glycoprotein (P-gp) is a brain protein that is part of the blood brain barrier. Differences in the activity of P-gp may help explain why some people with HIV develop MND. It is also possible that MND is partly due to inflammation in the brain. Researchers want to study P-gp and its effect on MND and HIV infection. Objectives: - To study P-gp and brain inflammation related to HIV infection. Eligibility: - Individuals between 18 and 60 years of age who have HIV and either do or do not have MND. - Healthy volunteers between 18 and 60 years of age. Design: - Participants will be screened with a medical history and physical exam. Blood and urine samples will be collected. - Participants will have one outpatient visit and one 3-day inpatient stay. - At the outpatient visit, participants will provide blood samples and have a lumbar puncture (spinal tap). The spinal tap will collect cerebrospinal fluid for study. - At the inpatient visit, participants will have two positron emission tomography (PET) scans of the brain. These scans will study brain activity and possible inflammation. One scan will involve a study drug called tariquidar, which blocks the activity of P-gp. A second lumbar puncture will be done before the first PET scan. Blood and urine samples will be collected daily.
The objective of this study is to prospectively evaluate the response of recombinant antithrombin (rAT) (ATRYN) in patients who are heparin resistant and are scheduled to undergo cardiac surgery.
The investigators would like to propose a pilot study evaluating the efficacy of etoposide combined with immunosuppressive agents for adult secondary hemophagocytic lymphohistiocytosis (HLH), in order to prove out whether the modification of previous HLH-94 or HLH-2004 protocol for childhood patients can improve the outcome and decrease the toxicities. The results of this pilot study will be a base of a more-improved phase-2 protocol.
The investigators hypothesize that transesophageal echocardiography is a valid method to obtain renal doppler hemodynamics2, 4. The goal of this study is to determine if there is a correlation between abnormal TEE resistive index measurements, intraoperative events and post-operative creatinine changes
