Filter by:Specific cardiovascular diseases, such as stroke and heart attack, have been shown to vary by ethnic group. However, less is known about differences between ethnic groups and a wider range of cardiovascular diseases. This study will examine differences between ethnic groups (White, Black, South Asian and Mixed/Other) and first lifetime presentation of twelve different cardiovascular diseases. This information may help to predict the onset of cardiovascular diseases and inform disease prevention strategies. The hypothesis is that different ethnic groups have differing associations with the range of cardiovascular diseases studied.
The investigators hypothesize that treatment with the iron chelator, Deferoxamine Mesylate, improves the outcome of patients with brain hemorrhage. The purpose of this study is to determine whether treatment with Deferoxamine Mesylate is of sufficient promise to improve outcome before pursuing a larger clinical trial to examine its effectiveness as a treatment for intracerebral hemorrhage.
Introduction: Increased intracranial pressure (ICP) is considered to be the most important intracranial mechanism causing secondary injury in patients admitted after acute traumatic brain injury (TBI) and intracranial haemorrhage (ICB) including subarachnoid haemorrhage (SAH). Currently, ICP can be measured and monitored only using invasive techniques. The two ICP measurement methods available - intraventricular and intraparenchymal - require both a neurosurgical procedure in order to implant the catheter and probes within the brain. The invasiveness of current methods for ICP measurement limits the diagnoses reliability of many neurological conditions in which intracranial hypertension is a treatable adverse event. A reliable, accurate and precise non-invasive method to measure ICP would be of considerable clinical value, enabling ICP measurement without the need of a surgical intervention. Aim: The aim of this study is to validate a novel non-invasive ICP measurement device by comparing its measurement with the "gold standard" invasive ICP-measurement by intracranial probe. The device used in this study has been been developed in the Telematic Science Laboratory at the Kaunas University of Technology, Lithuania. Methods: The non-invasive ICP measurement method will be assessed prospectively using repeatable simultaneous non-invasive and invasive (standard with intracranial probe) ICP measurements on patients presenting with TBI and SAH. The device method is based on two-depth transcranial doppler (TCD) technique for simultaneously measuring flow velocities in the intracranial and extracranial segments of the ophthalmic artery (OA). The intracranial segment of the OA is compressed by ICP and the extracranial segment of the OA is compressed by the pressure Pe externally applied by the device. Two-depth TCD device is used as an accurate indicator of the balance point (Pe = ICP) when the measured parameters of blood flow velocity waveforms in the intracranial and extracranial segments of OA are identical. The device has the same ultrasound transmission parameters as existing TCD devices and meets all patient safety criteria.
Subarachnoid Hemorrhage (SAH) can occur commonly in the setting of trauma or brain aneurysm. SAH accounts for 10% of all the strokes. Aneurysmal SAH accounts for 80 % of cases of non-traumatic cases of SAH, 6-8% of all strokes and 22-25% of all cerebrovascular deaths. Mortality can be 50% in the first few years of aneurysmal SAH rupture, 15% are severely disabled post SAH and only 20-35% having a moderate to good recovery it has gained lot of attention and pre-clinical and clinical trials of various agents have been tried to prevent poor outcome. The United States epidemiology data reveals the fact that 1% to 5% of adults have unruptured brain aneurysm and 30,000 people suffer from aneurysm rupture annually translating to brain aneurysm rupture every 18 minutes. Vasospasm is the most common SAH complication post 24 hours. It is the segmental or diffuse narrowing of the vessels especially the large vessels. Fifty percent of those patients who develop clinical vasospasm, progress to infarction and 15-20% will advance to disabling stroke or die of cerebral ischemia. The present treatment modalities are insufficient to prevent vasospasm. So, we need new treatment modalities to decrease the mortality and morbidity in SAH patients. The investigators hypothesize that Acetazolamide administration can prevent development of vasospasm after aneurysmal SAH.
This study seeks to assess whether populations of women in Latin America outside Quito, Ecuador are at increased risk for developing elevated body temperature above 40.0°C following PPH treatment with 800mcg sublingual misoprostol. The study will be carried out in hospitals representative of different regions of Latin America to explore environmental and genetic hypotheses related to the occurrence of misoprostol-induced fever. Postpartum blood loss, pulse and blood pressure will be systematically measured for all women enrolled to explore new clinical indicators for identifying women who require clinical intervention for excessive bleeding. Blood samples will be collected among women treated with misoprostol to investigate genetic factors responsible for elevated body temperature induced by misoprostol. The investigators hypothesize that rates of high fever (≥40.0°C) following misoprostol treatment (800mcg given sublingually) will be variable across settings. The investigators expect that the side effect profile following 800 mcg misoprostol given sublingually, in particular the rates of any shivering and fever ≥38.0°C, will be comparable to previous results using misoprostol for PPH.
This study is an investigator-initiated and conducted, international collaborative, regionally organised, multicentre, prospective, cluster randomised, crossover, blinded outcome assessment study to compare the effectiveness of the lying flat (0°) head position with the sitting up (=30°) head position, in the first 24 hours of admission to hospital for patients with acute stroke, on the poor outcome of death or disability over the subsequent 90 days.
This study is designed to see if abdominal ultrasound after planned cesarean delivery can identify women with ongoing intra-abdominal bleeding.
The aim of this study is to determine whether lactulose, L-ornithine L-aspartate, and rifaximin are effective in the prevention of the development of hepatic encephalopathy in cirrhotic patients with acute variceal bleeding
Objective: To assess the efficacy of lower uterine compression sutures (involved bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch) as a conservative treatment for the treatment of postpartum hemorrhage in women with placenta previa complete centralis. Method: This prospective study of 50 women with postpartum hemorrhage following removal of placenta previa complete centralis during elective cesarean section. All 50 patients will have lower uterine compression sutures (involving bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch). All patients will be followed postpartum for evaluation of uterine cavity and menstrual cycles
Although endoscopic colonic polypectomy has been an established procedure for two decades, the risk of bleeding is still higher after resecting of pedunculated polyps, because of the presence of a large artery in the stalk. Preventive methods such as endoloop and epinephrine injection have been proposed in the management of postpolypectomy bleeding in large colonic polyps. For prophylactic clip, there was no randomized controlled study assessing the efficacy in the prevention of postpolypectomy bleeding for the large pedunculated polyps. So the investigators designed a randomized controlled trial to confirm the efficacy of application of prophylactic clip in the prevention of postpolypectomy bleeding in large polyps.
