Active clinical trials for "Hemorrhage"

The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.

The primary objective of this multicenter study is to validate the AVICH score in terms of patient outcome prediction in AVM patients with associated ICH. Secondary objectives are the impact of pretreatment of the AVICH score. Patients outcome is measured using the modified Rankin Scale (mRS) and are grouped in favorable (mRS score, 0-2) and unfavourable (mRS score, 3-6) outcome at last follow-up (LFU). The following parameters, which are part of the AVICH score, will be compared between the 2 groups: ICH score including age, Glasgow Coma Scale (GCS) score, haemorrhage volume, presence of intraventricular hemorrhage (IVH), and localization of the ICH. Spetzler-Martin grade including AVM size, eloquent location, and venous drainage, as well as the Lawton-Young grade, including age, presence of ruptured AVM, and the nidus structure. In addition pre-/postruptured treatment modalities, including embolization, radiotherapy, surgery or no treatment will be analysed. Outcome (mRS) at 3 months, at 1 year, and at LFU will be compared. Multicentre validation study Key inclusion criteria: All patients with ICH associated AVMs and a modified Rankin Scale <2 (so 0-1) before hemorrhage Pretreatment (embolization, radiosurgery, surgery) before ICH is not an exclusion criteria. Key exclusion criteria: incomplete data set AVM Patients with only subarachnoid hemorrhage (SAH) or IVH and no ICH

It seems reasonable to assume that patients who present significant bleeding symptoms may have different quality of platelets than those without bleeding. This question was addressed in a study that examined platelet function in adult ITP patients, which try to determine whether this correlated with bleeding risk. Previous reports have suggested that measuring platelet function may help define patients at highest risk of bleeding. In addition, Middelburg and colleagues corrected platelet function for quartile of platelet count, using <32×10^9/L as the lowest cohort and >132×10^9/L as the top quartile. They demonstrated that increased platelet reactivity (as measured by flow cytometry) was associated with decreased risk of bleeding but particularly for those patients with the lowest platelet counts. Further studies in a larger cohort are needed to confirm this correlation. Our study aimed at standardizing a prediction model to evaluate the bleeding risk of adult ITP patients with the use of platelet function tests.

The aim of this cross-sectional study is to evaluate the hidden blood loss in patients who undergo laparoendoscopic single-site radical hysterectomy with pelvic lymphadenectomy and identity its risk factors.

A population-based registry in Catalonia of patients with acute spontaneous Intracerebral Hemorrhage, to investigate whether type of center and time from onset to admission is associated with functional outcome and mortality.

The investigators are planning that can these markers be used a predictive marker at SAH and for this aim we will study both patiens' blood sample and their CT image.

Postpartum hemorrhage (PPH) remains one of the leading causes of maternal mortality and morbidity worldwide, including in France, where it accounts for approximately 20% of maternal mortality. Although numerous studies have examined immediate PPH, very few have explored secondary (also called late) PPH. Moreover, there are no guidelines in France for the management of secondary PPH. Its frequency appears to vary from 0.2% to 3.0% of deliveries. It is, however, difficult to estimate because only severe secondary PPH will lead to hospitalization and the rare publications concern single-center studies. The cause of these secondary hemorrhages is often unknown, due to the lack of routine uterine aspiration. Nonetheless, this aspiration is not always medically justified. The principal objective of this study is thus to establish the incidence of severe late PPH in the general population.

The hypothesis is that the mortality of patients with non-varicose upper gastrointestinal bleeding after performing early gastroscopy who are admitted on weekends and night hours is higher than those admitted on weekdays or during daytime hours.

The incidence of Rosenthal basilar vein (BVR) variants (deep venous drainage variants) was relatively increased in patients with AN-SAH compared with patients with aneurysms. However, the inclusion criteria for AN-SAH patients in these studies were different. Some studies have investigated both PAN-SAH and NPAN-SAH, while some studies have only investigated PAN-SAH patients. However, we believe that NPAN-SAH may be the bleeding caused by non-BVR variation. Although previous studies did not find any association between NPAN-SAH and BVR variants, the results in their study were different, which may be due to the limited number of cases.

The purpose of this study is to observe the relationship between the changes of circulating exosomes and the development and outcome of the disease in patients with intracerebral hemorrhage, and to search for early serum markers and potential intervention targets for disease monitoring in patients with intracerebral hemorrhage
