Active clinical trials for "Hemorrhage"

Endometrial thickness has been used as an indicator of risk for endometrial hyperplasia and carcinoma in asymptomatic perimenopausal women. However, there is no cutoff value in perimenopausal women and the same thickness does not express the same endometrial volume in different endometrium because uterine lengths may be different and endometrial irregularities may exist. Many studies assessed endometrial volume measured by three-dimensional (3D) TVS as a predictor of malignancy in women with postmenopausal bleeding. To our knowledge there is no study assess endometrial volume measured by two dimension TVS in prediction of endometrial pathology, however it is cheap and available than 3D TVS.

The American College of Obstetrics and Gynecology, American Academy of Pediatrics and the World Health Organization have recently published recommendations related to placental transfusions in preterm infants. This project will review outcomes of preterm infants following a quality improvement implementation process in several delivery centers in Indiana. Centers involved in this project are also part of the Indiana Vermont Oxford Network (IRB#1003-84). Data is recorded for that network and the investigators site will be reviewing that data every 3 months from infants who have completed the Vermont Oxford Network collection. This project will specifically look at the incidence of intraventricular hemorrhage, necrotizing entercolitis, periventricular leukomalacia, sepsis and death following the implementation of the ACOG recommendations.

The aim of the study is to evaluate the uterine artery doppler just before labour in term low risk pregnancies. And to investigate with this measurement if investigators could foreseen the amount of postpartum hemorrhage looking at decreased in the hematocrit values.

The purpose of this investigator-initiated study is to compare the use of pupilometer and ultrasound assessment of optic nerve sheath diameter in predicting the ICP and to see if there is a value that could be used to indicate elevated ICP with either modality as these numbers are inconsistent throughout the literature. Patients that have either an external ventricular drain (EVD) or bolt placed will be enrolled in the study. After the EVD and bolt are placed the patient will undergo pupilometer examination (standard of care) followed by ultrasound assessment of the optic nerve sheath diameter (ONSD). The three values will be recorded. The same patient may have multiple readings performed if there is a change in ICP either spontaneously or due to intervention.

As bleeding is a major risk in bariatric surgeries, we aimed our study to find any predictors to such bleeding within the surgery or 30 days after surgery. The study is a retrospective study collecting patients data, surgeons data, and hospitals data in order to find if any of the factors influencing patients, surgeons or hospitals, has to do with bleeding in these surgeries and if it does impact bleeding in what way. The goal is finding a predictor that it's neutralizing may prevent bleeding in bariatric surgeries.

Spontaneous intracerebral bleeding also known as spontaneous intracerebral hemorrhage (sICH) constitute 10-15 % of all apoplexies. The Prognosis is considerably worse than it is for the larger population of patients suffering from cerebral thrombosis. Development of brain edema seemingly contributes to the disadvantageous prognosis. However, the mechanisms behind is only understood fragmentarily. By using multimodal neuro monitoring, the investigators seek to investigate electrophysiological and metabolic processes, which seem to accompany the formation of edema and clinical deterioration in patients suffering from sICH.

Background: About 5% of patients with acute coronary syndrome (ACS) have had previously ischemic stroke (IS) or transitory ischemic attack (TIA). This is a high-risk population, with a high incidence of ischemic events, and also of bleeding events. While the high ischemic risk in this population is attributed to a higher prevalence of cardiovascular risk factors, their predisposition to bleeding events is not well understood. Hypothesis: The increased bleeding risk in ACS patients with history of cerebrovascular event may be justified by a low platelet activity. Methods: Unicentric, prospective, case-control study, which included approximately 100 post-ACS patients with history of IS/TIA previously to the acute coronary event (Case Group) and 100 patients without IS/TIA (Control group). The groups were matched for gender, age, and ACS type and year of occurrence. All patients were taking aspirin, and the main exclusion criteria were use of dual antiplatelet therapy, previous hemorrhagic stroke, severe renal dysfunction, thrombocytopenia or coagulopathy. Main analysis: Platelet aggregation was evaluated by 6 methods: VerifyNow Aspirin®, VerifyNow P2Y12®, PFA 100®, thrombelastography (ReoRox®), light transmission aggregometry with ADP (LTA ADP) and epinephrine (LTA EPI) as agonists. Additional analysis: genetic, HDL transport and inflammatory evaliation

To compare two competing newly designed 3D sequences for black blood carotid plaque imaging techniques with the industry standard 2D sequnce for black blood.

The main aim of the study is to describes the outcomes of patients with Upper Gastrointestinal Bleed (UGIB) in a real-life setting. Additionally analyse assessed predictors of outcome, including the impact of hemostatic endoscopic and pharmacologic therapies.

The aim of the study is to evaluate if there is an association between platelet inhibition and surgery-related bleeding in patients undergoing non-cardiac surgery during dual antiplatelet therapy.
