Active clinical trials for "Hemorrhage"

The overall aim of this project is to prospectively determine whether MRI can improve the conventional neuroradiological evaluation (CT with or without cerebral angiography) of patients with a spontaneous ICH or IVH. The study design will also allow us to identify the added benefit of specific MR sequences and repeat MRI in the chronic stage, thereby allowing us to prospectively determine their value in a consecutive series of patients. This information should have a major impact on the management of these patients by providing data on the diagnostic yield of routine MRI in patients presenting with a wide variety of causes for ICH or IVH. These data will help guide the diagnostic evaluation and the management of brain hemorrhage patients in the future.

The purpose of this study is to determine the safety and efficacy of a continuous combined oral contraceptive pill (CCOCP) regimen. The investigators hypothesize that there will be a decrease in the number of vaginal bleeding days in the continuous regimen compared to a traditional 21/7 regimen. In addition, the investigators hypothesize that there will be increased endometrial and ovarian suppression in the CCOCP regimen.

This study will define the limits of subretinal hemorrhage parameters that are consistent with a good visual outcome with aggressive anti-VEGF treatment in patients with neovascular age-related macular degeneration (NVAMD).

This study is a single center prospective randomized control trial comparing the utility of performing capsule endoscopy compared to conservative management with oral iron therapy as the initial course of action in patients with non-severe obscure occult or obscure overt gastrointestinal (GI) bleeding. The investigators hypothesize that outcomes in patients with non-severe obscure GI bleeding who receive conservative therapy with oral iron will not differ to those on oral iron who undergo capsule endoscopy.

Several recent clinical trials have documented that early aggressive resuscitation approached guided by defined hemodynamic variables using thoughtful protocols may improve outcome. The concept underscored by this newer trial was that appropriate resuscitation prevents subsequent tissue injury even if overt shock is present, if the resuscitation is carried out early enough.

Glioma patients with history of venous thromboembolism (VTE) treated on low molecular weight heparin (LMWH) and who decided with their physician to convert to Apixaban (oral drug) will be enrolled into our study and will collect data regarding recurrent VTE and Intracranial hemorrhage and the incidence of these events.

The purpose of this research study is to evaluate the ability of medicines called tamoxifen or estradiol to prevent annoying vaginal bleeding for arm implant users.

The primary purpose of this study is to assess the accuracy of the newly released Masimo SpHb Butterfly Sensor with RevK version and compare the results to a blood hemoglobin level analyzed in the UCSF Clinical Laboratories. A secondary purpose is to assess the blood hemoglobin using the Masimo Pronto-7 hand-held device immediately prior to surgery.

The purpose of this retrospective study is to test the hypothesis that uncontrolled tachycardia serves as a risk factor for adverse cardiovascular events and poor outcome after Subarachnoid Hemorrhage (SAH).

Aspirin is very common in older patients. Therefore many of the investigators patients have aspirin. The aim of the study is to proof that Transurethral Surgery of the bladder or the prostate can be performed with aspirin.
