Active clinical trials for "Hemorrhage"

The rationale of this study in UGIB patients is to assess whether the prediction of mortality and morbidity using AIMS65 score improves when used in combination with RDW in the emergency department setting.

This is a retrospective observational study to investigate the clinical, analytical and neuroimaging data generated during routine clinical management of intracerebral hemorrhage. The study will review the data from about 500 patients attended during the last ten years in the Neurology Department of Hospital Parc Taulí de Sabadell. The aim is to measure the size of the lesion in neuroimage (TC and MRI), the edema, the alterations in diffusion weighted images and to correlate this data with clinical parameters and analytical measurements. With this approach investigators plan to investigate the incidence of hematoma growth, the role of perilesional edema and diffusion changes, and the relation between neuroimaging findings and clinical outcome. The study also try to establish significant correlations between clinical and analytical data, the clinical outcome and and the magnitude of changes in neuroimaging.

A retrospective, observational single centre study of electronic medical records of discharged patients who were admitted to from 1 January 2015 to 31 December 2018. Period of data collection was from 5 August 2019 to 15 September 2019.

This is a prospective observational study among women at high-risk of postpartum hemorrhage, in their third trimester who are admitted to Labor &Delivery in spontaneous labor, for induction of labor, or for scheduled cesarean section.

Collection of relevant data form patients who were treated in the Ghent University Hospital in the context of a placental remnant lager than 4 cm, performing statistical analyzes on the collected data, reviewing the literature on the subject and formulation of a recommendation for treatment of these large placental remnants.

The prevalence and clinical implications of prolonged cerebral vasospasm in patients with subarachnoid hemorrhage are unknown.

In this study we aim to determine the incidence of fatal spontaneous subarachnoid haemorrhage outside hospital. Also, we aim to investigate these patient´s pattern of contact to the health care system immediately before their death and to describe the circumstances under which they died.

DELPhI software developed for the analysis of EEG recordings in response to magnetic stimulation in relation to clinical data.

The purpose of this study is to estimate the proportion of Ventricular Assist Device (VAD) patients with abnormal gastrointestinal bleeding as assessed by HemoQuant fecal occult blood test. Also, in patients with gastrointestinal bleeding present, to summarize the extent of gastrointestinal bleeding; to examine the behavior of HemoQuant fecal occult blood test over time by estimating the proportion of VAD patients with a positive test prior to implantation; at one week, one month, three months, six months and one year post implantation, and after explantation of the VAD and to evaluate whether presence of any abnormal fecal HemoQuant test is predictive of a future major bleeding event.

Since the introduction of vitrectomy in 1971, this procedure has become the third most frequently performed ophthalmic surgery. Approximately 225,000 vitrectomies are performed annually in the United States and indications continue to expand. Known long-term complications of vitrectomy are relatively few and include retinal detachment and cataract formation. Although much has been written in the literature concerning acute rises in intraocular pressure (IOP) in the immediate postoperative period, there is surprisingly little information on long term IOP outcomes after vitrectomy. A recent report by Chang given at the LXII (62) Edward Jackson Memorial Lecture hypothesized a causal relationship between vitrectomy and open-angle glaucoma (OAG) via oxidative stress exacerbated by removal of the crystalline lens. A second report by Luk and colleagues reported similar conclusions in a modified cohort. Both studies, were retrospective in nature and did not perform baseline evaluations to exclude pre-existing glaucoma. Furthermore neither study accounted for natural history. Finally, our analysis has not reproduced similar results. The primary purpose of this study is to analyze the full spectrum of optic nerve and macular changes between vitrectomized study eyes and their non-vitrectomized fellow eyes to control for natural history. Baseline evaluations will include examination by fellowship trained retina and glaucoma specialists, fundus photography, autofluorescence, optical coherence tomography (macula and optic nerve) and automated visual field testing. At 3 month then annually for 5 years after vitrectomy surgery, the cohort will undergo similar evaluation.
