Active clinical trials for "Ischemia"

Type of Study: Pilot Study monocenter Study Duration: 18 months Subject Participation Duration: The patients are enrolled for the time of the blood withdrawl. Follow up visit will be after 12 months from the enrollement. Objectives: The project will have two major objectives: A)To validate the prognostic value of vascular progenitor cells, identified by flow cytometric analysis of antigenic phenotype, in a cohort of 109 patients with type-2 diabetes complicated by ischemic foot ulcers. Events are: cardiovascular mortality, major amputation, post-angioplasty restenosis , and development of new atherosclerotic plaques in treated limb B)To determine the mechanisms responsible for vascular progenitor cell dysfunction in the perspective of new therapies for the cure of the diabetic foot.

The present study is to determine the ability of urinary total adiponectin and its isoforms excretion in the prediction of contrast induced nephropathy (CIN) in the patients undergoing PCI.

The aim of the work is to; elucidate how the presence of carotid stenosis influence the pattern of stroke and also how it interact with other risk factors for stroke. Also identify predictors of intracranial stenosis and outcome in patients with carotid stenosis with or without intracranial stenosis.

In the current study the investigators intend to evaluate the mode of anesthesia on ischemia modified albumin and outcome in patients with traumatic brain injury undergoing emergency craniotomy

The primary aim of the current research project is to answer the question, whether plasma trimethylamine N-oxide (TMAO) level may be used as a marker of ischemic changes in the brain. TMAO is associated with endothelial dysfunction, inflammation and oxidative stress. The hypothesis is that circulating TMAO level may predict leukoaraiosis (LA) and/or stroke. Secondary, the investigators would like to examine whether plasma TMAO concentration is related to cognitive impairment and determine whether choline consumption is associated with an incidence of LA severity and dementia.

To evaluate ocular blood perfusion status and the possibility of craniocerebral vascular lesions of patients with ocular ischemia syndrome (OIS) using arterial spin labeling (ASL) magnetic resonance imaging technique. To evaluate the specificity, sensitivity and accuracy of arterial spin labeling (ASL) magnetic resonance imaging technique in OIS diagnosis, compared with the traditional routine examination method.

Aim of the study is assessment the prevalence of the low ankle-brachial index (ABI) defined less than or equal 0.9 in patients with acute cerebral ischemic event (stroke or transient ischemic attack) and determinate the correlation between ABI and internal carotid artery stenosis (ICAS) in the acute cerebral ischemic patients. The low ABI is a strong marker of generalized atherosclerosis. LEAD is a strong independent predictor for stroke.

Aim of the study is to evaluate the usefulness of interleukin 33 in the blood plasma in patients with the acute ischemic stroke of the brain in relation to mode of treatment (thrombolysis, thrombectomy, no treatment), risk factors in correlation with other inflammatory state markers (hsCRP, morphology with smear ). Blood is collected on the first and seventh days of stroke. The purpose is to clarify utility of IL 33 as a biomarker of acute stroke.

The femoro-popliteal arterial segment is one of the most frequent locations for atherosclerosis. Its management is mainly endovascular (standard and coated-balloon angioplasty, stenting). However, the structural features of the atherosclerotic disease in regards to patient's risk factors and past medical and surgical histories are not well studied. Furthermore, the histological analysis of the femoro-popliteal arterial segment is rare in the literature, and made difficult mostly because of the length of this segment. There is a clinical need for better understanding of atherosclerotic lesions in this location, with as further goal, a better management of this disease.

Perinatal asphyxia is common cause of acquired neonatal brain injury in neonates associated with hypoxic-ischemic encephalopathy, leading to long-term neurologic complication or death. In 2000, the neonatal mortality rate in Egypt was found to be 25 per 1000 live birth. In this survey, hypoxic ischemic encephalopathy accounts for 18% of neonatal mortality and is the second most common cause of neonatal death.
