Peripheral artery disease (PAD) due to leg artery blockages can result in painful leg muscles, skin ulcers and infection due to poor blood flow. In severe forms, the only treatment may be amputation. Adult stem cells injected into affected legs may cause new blood vessel formation and improve blood flow. The purpose of this study is to determine the feasibility and safety of injecting adult stem cells into the leg muscles of patients with severe PAD, in an attempt to improve blood flow.
To evaluate the accuracy of ischemic preconditioning (IPC) as a protective maneuver against ischemia/reperfusion lesion in patients undergoing major liver resection with intermittent portal triad Clamping (IPTC). Summary Background Data: For sake of safety and to avoid excessive blood loss during parenchymal transection, vascular inflow occlusion is an effective trick but may cause ischemic damage to the remnant liver and can lead to liver failure in case of chronic liver disease. IPTC has been proven to be superior to continuous hepatic pedicle clamping as it preserve liver remnant from severe ischemia/reperfusion lesion, so does IPC. Yet, if IPC is beneficial if liver resection is performed under IPTC has never been demonstrated in a randomised controlled trial (RCT). The investigators designed a RCT to assess the impact of IPC in patient undergoing major liver resection with intermittent vascular inflow occlusion.
Cardiac stress testing with functional nuclear imaging is an invaluable technique in the diagnostic and prognostic evaluation of patients with known or suspected ischemic heart disease. Selection of the appropriate type of nuclear stress test: exercise stress Myocardial Perfusion Imaging (MPI) versus pharmacologic stress MPI is crucial for not only diagnostic accuracy and prognostic evaluation, but also for sound clinical decisions and resource utilization. The Duke Activity Status Index (DASI) is a 12-item questionnaire that utilized self-reported physical work capacity to estimate peak metabolic equivalents (METs) and has been shown to be a valid measurement of functional capacity. The investigators hypothesized that the DASI may be the screening tool that evaluates functional capacity and guides selection of the optimal stress MPI study.
Pneumonia is a frequent complication of acute stroke and is associated with increased mortality and long-term impairment in the affected subjects. In previous studies, a number of clinical (e.g., dysphagia, severe neurological impairment, mechanical ventilation), radiological (e.g., large infarctions in the territory of middle cerebral artery, insular infarction) and biochemical (e.g., increased serum levels of C-reactive protein, decreased levels of CD4+ T-lymphocytes) findings have been reported as risk factors of stroke-related chest infection. The present study (PRECAST) aims to identify a small set out of these previously described risk factors that can predict stroke-related pneumonia with high sensitivity and specificity.
The clinical investigation is a prospective, international, multi-centre, randomized (1:1) trial with follow up investigations at 1, 3, 6 and 12 months. Patients will be randomized either to treatment with stenting with the Astron Pulsar SE (4 or 5 mm diameter) stent or to PTA with optional bailout stenting in case of PTA failure. The primary objective of this study is to show clinical improvement in the outcome of patients with symptomatic critical limb ischemia or severe intermittent claudication (Rutherford 3, 4, 5) treated with the Astron Pulsar SE (4 or 5 mm diameter) in comparison with PTA or optional bailout stenting in case of PTA failure.
The aim of the study is to investigate treatment with Leukostim (Filgrastim; granulocyte-colony stimulating factor; G-CSF) for acute ischemic stroke.
In this study, patients were divided into 3 group with 35 cases including: 1.oxygen 2.enalapril 3.control. In the beginning of the study, best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and optical coherence tomography (OCT) were measured. Patients in the oxygen group were given oxygen 10 lit/min 1 hour twice a day at the first month, once a day at the second month and every other day at the third month. In the enalapril group, patients were given enalapril 5 mg every night and placebo was given for the patients in third group. At the end of first month the patients' vision was checked again and at the the end of the third month the first physical examinations were performed. In the first group, arterial blood gas (ABG) was taken before and after oxygen therapy as well.
The primary goal of this trial is to determine if individuals with acute ischemic stroke treated with a medium dose of IV rt-PA plus IV eptifibatide started within 3 hours of symptom onset are more likely to have a better outcome than individuals treated with standard IV rt-PA alone.
The purpose of this trial is to determine if intravenous administration of the metal ion trapping agent DP-b99 up to 9 hours following acute ischemic stroke onset, and then for 3 additional days (4 consecutive days in total) is effective in improving long term outcome. Patients will be followed up for 3 months after the stroke.
