The Impact of Laparoscopic Versus Open Surgeries on the Incidence of Postoperative Deep Vein Thrombosis...

Deep Vein Thrombosis

Deep vein thrombosis (DVT) is a common complication of surgery, which could result in pulmonary embolism (PE). PE is a serious and potentially life-threatening syndrome. The purpose of this study is to investigate the impact of laparoscopic versus open surgeries on the incidence of postoperative DVT in patients with gastrointestinal malignancy

ADAMTS-13 LEVEL AS PREDICTIVE BIOMARKER FOR DEVELOPMENT OF PORTAL VEIN THROMBOSIS IN LIVER CIRRHOSIS...

Liver Cirrhosis

Patients with cirrhosis of viral etiology (HCV/HBV); Patients with cirrhosis of any other etiology (alcohol, idiopatic, autoimmune). Planned Number of cirrhotic subjects 200 patients Inclusion Criteria Subjects (18 yr old) with liver cirrhosis of any etiology, Exclusion Criteria All patients should not have hepatocellular carcinoma or other malignant tumors, they should not be treated with anticoagulant / antiplatelet agents, not affected by PVT already diagnosed and not suffering from congenital coagulation disorders (haemophilia A / B, von disease Willebrand, another congenital deficiency of coagulation factors) or severe thrombocytopenia (<30,000 Plt / μL). Subject has participated in another clinical study within 30 days prior to study enrollment or is scheduled to participate in another clinical study on cirrhosis Primary Objective To describe the prospective modification of ADAMTS-13 level and other coagulation variables (e.g. FVIII, VWF:Ag/VWF:act) in cirrhotic patients during 18 months from the enrolment and to verify their predictive role as biomarker of development of portal vein thrombosis (PVT) Secondary Objectives To describe prospectively the modification of ADAMTS-13 level as a function of the etiology of cirrhosis Statistical analysis The total duration of the study will be of 12 months. The sample size of 200 subjects will be selected as a feasible number of patients to be recruited in a period of six months. The patients will be consecutively enrolled and followed for 18 months. As a result, in a follow up period of 18 months about 20-25 cases of PVT are expected. Continuous variables will be expressed as means ± standard deviations. In addition to descriptive statistics (location parameters), univariate analysis will be performed on each parameter and development of PVT during the follow up period. In previous observational studies both 1) a reduced PV flow [prospectively] and 2) a reduction of ADAMTS-13 are significantly associated with PVT. These associations will be investigated prospectively and analyzed simultaneously by a multivariate analysis and ROC curve to establish the sensitivity and specificity of these parameters as predictors of PVT development. Analyses will be performed using available data

HemorrhageCerebrovascular Accident3 more

The objective of this study is to evaluate the safety of antiplatelet (APA)therapy continuation in patients undergoing lumbar spine surgery (laminectomy, discectomy and foraminotomy), and to gather evidence-based data regarding postoperative outcomes potentially related to APA management.

Incidence of Complications of Peripheral Venous Access in the Type 2 Diabetic Population

Diabetes MellitusType 25 more

Diabetes Mellitus type 2 (T2DM) is one of the most frequent metabolic diseases worldwide. It is expected that in 2035 around 600 million people will suffer from the disease. A recent systematic review has estimated that the direct annual cost of Diabetes worldwide treatments and care is over $ 827 billion and has been independently associated with nosocomial complications, thrombosis-like infections and prolonged admissions. In addition, it is estimated that up to 90% of patients in acute hospitals require a peripheral venous catheter which are associated at the same time with mechanical, infectious and thrombotic acute complications. Recently the emergence of new medium-sized peripheral devices (Midline®) and new peripheral central venous access catheters (PICC), which are more biocompatible, are opening new clinical possibilities with the aim of improving safety and comfort during treatment time and the reduction of associated complications. With all this, a observational case-control study has been proposed in order to analyze the impact of T2DM disease and its associated complications on the patient requiring peripheral venous access. Furthermore investigators will consider if these new peripheral devices can be a remarkable benefit for these patients. This study will be carried out at the Vall d'Hebron University Hospital in Barcelona, Spain

Safely Ruling Out Deep Vein Thrombosis in Pregnancy With the LEFt Clinical Decision Rule and D-Dimer...

PregnancyDeep Vein Thrombosis

This is prospective cohort study in pregnant women who present with signs and symptoms of possible deep vein thrombosis (DVT). All patients will have the same method of assessment of their DVT symptoms (the LEFt clinical decision rule will be applied and D-dimer test will be done) to determine if a compression ultrasound is required. All patients will be followed for a period of 3 months.

The DARE Warfarin CER Study

Deep Venous ThrombosisPulmonary Embolism

Approximately half a million Americans annually experience venous thromboembolic disease, including deep venous thrombosis (DVT) and pulmonary embolism (PE). Since 2010, four new oral anticoagulants have been approved for marketing in addition to the vitamin K antagonist warfarin. Very limited head-to-head data exists comparing these treatment options, leaving patients, clinicians, and other stakeholders with little guidance for selecting the best strategy that balances recurrence reduction with risk of bleeding. In the DARE Warfarin CER Study, the researchers compare all five currently available oral anticoagulant agents for the extended treatment of DVT and PE, as well as no extended treatment. This study also aims to evaluate whether treatment heterogeneity exists for specific populations, such as older patients or those with renal dysfunction. In a secondary aim, the study will also leverage a database of linked electronic health record-insurance claims to validate diagnosis definitions and account for potential residual confounding by factors unmeasured in claims data. As the patient population includes all Medicare novel anticoagulant users and large numbers of commercially insured and Medicaid patients, the results will likely be transportable to the majority of US patients experiencing a DVT or PE. Pursuant to the objectives of the Patient-Centered Outcomes Research Institute, a study advisory committee consisting of key stakeholders will be actively involved in the study design and dissemination of results.

Long Term Outcomes of Venous Thromboembolism

Post Thrombotic SyndromeChronic Thromboembolic Pulmonary Hypertension1 more

This prospective observational follow-up study is designed to assess the long-term outcomes after Venous thromboembolism (VTE) and to assess the effect of the new oral anticoagulant (NOAC) rivaroxaban on the prevalence of post-thrombotic syndrome (PTS). The study will not be testing any formal hypothesis.
