Active clinical trials for "Thrombosis"

Oral antithrombotic medications (OAM) are used for the prevention and treatment of thrombotic disorders. Among hemorrhagic complications of OAMs, intracranial hemorrhage (ICH) may have particularly devastating consequences with high morbidity, disability and mortality rates. The efficacy and safety profiles of OAMs are generally assessed in randomized controlled trials (RCT), but included patients are often highly selected and may not be representative of users in everyday clinical practice in terms of follow-up routines, age, gender, drug compliance, and polypharmacy. Moreover, it is often unclear whether or not traumatic ICHs are registered and reported in RCTs. Drifts in indications and treatment criteria may also be seen in everyday practice and drug discontinuation due to precautionary concerns including compliance, fall risk and comorbidity may be forgotten. Collectively, these factors may lead to other and potentially higher traumatic ICH rates in general clinical use than reported in RCTs. The incidence rates of traumatic ICH in patients on OAMs in the general population remain unknown. In this nationwide registry based pharmacoepidemiological study we will investigate the incidence and case fatality of traumatic ICH in users of OAMs in Norway from 2008 through 2014.

This is a multicenter randomized clinical trial (RCT) comparing two modes of antibiotic delivery: Control: Intravenous Antibiotic Delivery (IVAD) Treatment: IVAD + TAAD The Food & Drug Administration (FDA) has approved our Investigational New Drug (IND) application to conduct this RCT. An IND application was necessary because subcutaneous injection of antibiotics in general, and cefazolin and metronidazole in particular are considered to be "off-label". In addition, the tumescent formulation of cefazolin (1gm) and metronidazole (500mg/100ml) in a dilute solution of lidocaine (1gm), epinephrine (1mg) in 100ml and sodium bicarbonate (10mEq/10ml) added a 1000ml bag of 0.9% sodium chloride (total volume 1210ml) is also considered "off-label." This trial will also prospectively study the HK Surgical SubQKath, an over-the-needle subcutaneous catheter specifically designed to deliver relatively large volumes of a relatively dilute TAAD solution. The TAAD trial will document the safety and efficacy of the HK SubQKath

the investigators hypothesize that some of these polymorphisms contribute to VTE risk in women using COC, and that their screening could to help assess individual risk of VTE before COC prescription. In order to test this hypothesis the investigators propose to build a predictive score for VTE in women using COC based on clinical and biological factors. To this end the investigators have a large case study (including 766 patients) recruited at the "Centre d'Exploration des Pathologies Hémorragiques et Thrombotiques" (CEHT) of the laboratory of Hematology (La Timone Hospital, Marseille) between 2003 and 2013. The cases had a personal history of documented VTE while using COC (PILGRIM study). A great number of clinical and biological relevant phenotypes in the field of VTE have already been collected (including 14 polymorphisms selected on the basis of their biological plausibility and the existence association studies).To our knowledge it is the largest study specifically conducted in order to assess genetic factors associated with VTE in women using COC. These 766 cases will be compared to 766 controls from the general population (cohort Nutrinet-Santé). Then, the predictive values of the score will be assessed in an independent multicentric validation study that the investigators will set up in the field of this project. Our study should allow a better understanding of the genetic and environmental factors involved in VTE related to COC use. Besides, this project aims to respond to a major public health issue giving an effective tool for the decision of prescribing COC.

The main objective is to reduce the incidence of venous thromboembolism (VTE) in orthopedic postoperative patients based on the potential benefit of using rivaroxaban as a monotherapy. It is around efficacy and safety evaluation of using rivaroxaban as a monotherapy prophylactic agent in patients undergoing orthopedic surgeries taking into the account the reliable selection of patients most benefit. Answering questions about additional cost benefit from the perceptive of the cost-effective analysis on extrapolating the results emerged to our university teaching hospital setting are going to be evaluating as well.

To assess the efficacy of Taurolock-hep500™ as anticoagulant and antimicrobial catheter lock solution in comparison to unfractionated heparin as alock solution to improve performance of hemodialysis catheters and quality of hemodialysis .

A preliminary clinical usability study to assess design, comfort, wearability, and acceptance of Recovery Force's Deep vein thrombosis (DVT) cuff

The purpose of this study is to examine the impact of cranioplasty on cerebral hemodynamic and blood flow as prognostic factor in patients receiving decompressive craniectomy for Head injuries, Subarachnoid haemorrhage, intra-cerebral haemorrhage, cerebral dural sinus thrombosis, malignant middle cerebral artery stroke.

Venous thromboembolism (VTE) remains a major cause of maternal morbidity and mortality in developed countries. Objective diagnosis of pulmonary embolism (PE) and/or deep vein thrombosis (DVT) in pregnancy is crucial. Failure to identify PE or/or DVT will place the mother's life at risk, and unnecessary treatment will not only expose her to anticoagulants but will also label her as having had VTE. Thus, this diagnosis has serious implications for the management of her present pregnancy, and for other aspects of her life ranging from contraception to thromboprophylaxis in future pregnancies and hormone replacement therapy in later life. It is therefore critical that all women with symptoms or signs that suggest venous thromboembolism have appropriate investigation and diagnosis based on objective diagnostic tests. The current diagnostic approach in suspected PE is based on sequential diagnostic tests: 1) assessment of clinical probability, 2) fibrin D-dimer measurement, 3) compression ultrasonography of lower limb veins and 4) multi-slice computed tomography (MSCT). However, physicians are reluctant to perform MSCT in pregnant women because of potential adverse effect of radiation exposure to the fetus. For this reason, ventilation/perfusion or perfusion-only lung scan has been the cornerstone of PE diagnosis in pregnant women. Indeed, perfusion lung scan was assumed to be associated with less radiation than computed tomography (CT). However, this technique is now widely abandoned in the usual diagnostic strategy of PE for the following reasons: it is not widely available; its interpretation may be difficult and the test may be inconclusive in the presence of other chest abnormalities. Moreover, recent data convincingly show that the radiation exposure associated with single-slice or multi-slice CT exposes the fetus to less radiation than perfusion lung scan. However, the use of CT has never been adequately validated in pregnant women with clinically suspected PE. The investigators, therefore, plan to set up a prospective management study in which pregnant women with suspected PE will undergo a sequential diagnostic strategy based on 1) assessment of clinical probability 2) D-dimer measurement 3) compression ultrasonography, and 4) MSCT. Nowadays, the overestimated fear of radiation exposure for the fetus leads to an irrational attitude and inadequate investigations in pregnant women with suspected PE, even though both European [3, 4] and North-American guidelines [5] suggest that only objective testing may accurately rule out the disease. The proposed study should lead to an increased awareness of the risks and benefits of appropriate imaging in pregnant women suspected of PE and should result in a more rational management of this under-studied patient group.

Investigate, through a randomized, open, parallel and comparative, non-inferiority of heparin sodium produced by laboratory Hipolabor compared to heparin manufactured by APP in patients on hemodialysis due to renal failure, through the control of hemostasis, verified by formation of clot (fibrin) in the hemodialysis system and pharmacodynamic parameters (TTPA and Anti-Xa) during the use of heparin

The objective of the GRAVITAS trial is to determine whether tailored anti-platelet therapy using the Accumetrics VerifyNow P2Y12 assay reduces major adverse cardiovascular events after drug-eluting stent implantation.
