Active clinical trials for "Hemorrhage"

This study will begin to define these critical determinants for patients undergoing procedures in the hybrid interventional cardiology/cardiac surgery suite. In future studies, the data obtained from this study will be used to prospectively stratify patients in terms of bleeding verses thrombotic risk to design studies to optimize anticoagulation and anti-platelet therapies in the hybrid setting.

The aim of the study is to evaluate the cortical excitability in the severe brain injured patients. We hypothesize that: There is a continuous decrease in intracortical inhibition from healthy subjects to awake patients with severe brain injury, and to patients with impaired consciousness. Decreased intracortical inhibition correlate with the degree of impairment assessed with the clinical scores in patients with severe brain injury.

The purpose of this study is to assess whether adherence to NVUGIB guidelines is improved with implementation of a national, tailored multifaceted intervention. Outcomes include adherence rates to two key endoscopic and pharmacological therapy guidelines together (primary), or adherence to these individually as well as to other recommendations (secondary). Patient outcomes and economic data are also assessed (tertiary).

The Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) trial is a multicenter clinical trial conducted to assess the effects of long-term antiviral drug therapy on the progression of liver disease in patients who have advanced chronic hepatitis C and have not responded to prior therapies. Chronic hepatitis C is a long-lasting viral infection affecting the liver that may lead to permanent liver damage and cirrhosis (replacement of healthy liver cells by scar tissue). If left untreated, a proportion of patients with chronic hepatitis C will be at risk for complications of liver disease. The drug therapy in the HALT-C trial was designed to clear the hepatitis C virus from the patient s system in order to prevent or mitigate these potential complications. The purpose of this research is to determine if patients with chronic hepatitis C who experienced clearance of hepatitis C virus (known as a sustained virologic response, or SVR) during the HALT-C trial have developed any complications of their liver disease. This study will include 180 subjects who participated in the initial phase of the HALT-C trial and experienced an SVR. The participants will visit the National Institutes of Health for an in-person study visit. During the visit, patients will have blood drawn for lab tests to monitor the progress of their liver disease, and may be asked to undergo an ultrasound examination of the liver to detect any abnormalities that may be attributed to liver cancer. Patients will also answer questions about their medical history particularly any outcomes or events related to their hepatitis C that have occurred since the HALT-C trial and may be asked to sign a release of information to allow researchers to obtain medical records from other clinics or physicians where they have received treatment. ...

The goal of this observational study is to develop and validate a predictive score of 1-year outcomes in subarachnoid hemorrhage (SAH) patients receiving aneurism coiling. Using our database filled up prospectively, the investigators plan to collect clinical, biological and radiological admission characteristics of coiled SAH cases and their 1-year Rankin outcome score during 5 years (2003-2007). The investigators plan to confirm our score in a validation cohort (from 2008 to 2009).

The hypothesis of this study is that the antifibrinolytic drugs aprotinin and tranexamic acid equally influence bleeding tendency and transfusion requirement in patients undergoing first time cardiac procedures with a low risk of increased postoperative bleeding.Only patients undergoing first time CABG or first time aortic valve replacement are included in this study.

Pupose: Takotsubo cardiomyopathy is a rare and not well-known complication of the subarachnoid hemorrhage. This form of heart failure, called as "broke heart" or "apical ballooning syndrome", was first described by Japanese authors at the beginning of 1990's. 1.5-2.2% of acute coronary syndrome is Takotsubo cardiomyopathy. Its predisposing factors, hypothetical parthenogenesis, diagnostic criteria and therapeutic methods are already known from the literature. The study intends to include all patients over 18 years of age who were admitted to our clinic within 48 hours after the bleeding regardless of gender, neurological status or age. Data to be registered within 24 hours after admittance: Instruments: Intracranial blood flow characteristics:TCCD - using Transcranial Color Doppler; systolic, diastolic and mean blood flow velocity, Systolic / Diastolic ratio, pulsatility index ECG abnormalities: Corrected QT Interval (QTc), T wave, ST segment, arrhythmia Echocardiography (Ejection fraction%, exact location and degree of cardiac wall motion abnormalities) - documented with video recording Hypothesis: The risk of Takotsubo cardiomyopathy (TS) is increased if SAH is associated with more severe state, a greater degree of bleeding, intraventricular and/ or intracerebral hemorrhage. The definitive care of patients is postponed due to the appearance of TS, which could affect the final outcome.

HeadSense (HS)-1000 device, a proprietary non-invasive brain monitor, is expected to safely and accurately monitor physiological signs of the brain with minimal discomfort to patients, providing information about normal or abnormal brain-related conditions and providing decision-making support for physicians. The investigators hypothesize that the HS-1000 is capable of detecting vasospasm using the raw acoustic data derived from the noninvasive procedure.

This study is aimed at identifying the efficacy of Tachosil® for prevention of hemorrhage in patients with cervical intraepithelial neoplasia or cervical cancer after undergoing a loop electrosurgical excisional procedure (LEEP). Primary endpoint: Bleeding period within two weeks after surgery Frequency of additional treatment due to bleeding within two weeks after surgery Secondary endpoint: Amount of bleeding within two weeks after surgery Infection frequency at external genitals, vagina and cervix within two weeks after surgery Change in life quality after surgery
