BACKGROUND: Optimal prophylactic strategies in pregnant women with a history of venous thromboembolism (VTE) are unknown. PATIENTS AND METHODS: We conducted a retrospective cohort study of consecutive pregnant patients with a previous VTE history. Patients were followed until 6 weeks postpartum. Patients with a previous unprovoked event (including antepartum VTE) received antenatal prophylaxis, mostly with low dose low molecular weight heparin (LMWH). All patients received prophylaxis for six weeks after delivery...

BACKGROUND & AIMS: A simultaneous decline in pro- and anticoagulant drivers in patients with liver diseases results in a 'rebalanced' hemostatic system, even in acutely ill patients. Nevertheless, both bleeding and thrombotic events are common. Here, we explored efficacy of pro- and antihemostatic strategies in compensated and acutely ill cirrhotics which may be unpredictable given the profound hemostatic changes. METHODS: We tested the effects in vitro of the addition of clinically relevant doses of commonly used pro- and antihemostatic strategies in plasma from healthy individuals (n=30) and patients with compensated (n=18) and acutely decompensated cirrhosis (n=18), and acute-on-chronic liver failure (n=10)...

BACKGROUND AND PURPOSE: Cerebral venous thrombosis (CVT) is a rare but life-threatening disease. Timely and proper treatments are the keys in saving patients' life and preventing from permanent neurological deficits. We performed this network meta-analysis to evaluate the role of anticoagulation in CVT, especially for the patients accompanied with hemorrhagic stroke. METHODS: PubMed, Embase, Web of Science, Cochrane Database, and Chinese Biomedical (CBM) databases were searched comprehensively to select eligible articles (up to 30 June 2017)...

Purpose Venous thromboembolism (VTE) is common in patients with cancer. Long-term daily subcutaneous low molecular weight heparin has been standard treatment for such patients. The purpose of this study was to assess if an oral factor Xa inhibitor, rivaroxaban, would offer an alternative treatment for VTE in patients with cancer. Patient and Methods In this multicenter, randomized, open-label, pilot trial in the United Kingdom, patients with active cancer who had symptomatic pulmonary embolism (PE), incidental PE, or symptomatic lower-extremity proximal deep vein thrombosis (DVT) were recruited...

Esophageal cancer is one of the most prevalent types of cancer globally. With current treatment options, the survival is poor, and there are ongoing efforts to find new and more efficient therapeutic approaches. There are several reports on the anti-tumoral effects of low-molecular-weight heparins (LMWH). We have assessed the possible survival benefits and underlying mechanisms of LMWHs in malignancies with a focus on esophageal cancer. We conclude that the effects of LMWHs on survival of cancer patients is probably due to a combination of direct anti-tumoral, anti-angiogenic, and immunomodulatory effects and indirect effects on the coagulation system...

Deep venous thrombosis is one of the common complications after major surgery in the Department of Orthopedics. The selective knee replacement of the lower extremities is more likely to cause the occurrence of DVT. The most commonly used anticoagulants in the Department of Orthopedics now include low molecular weight heparin (LMWH), Rivaroxaban, ordinary heparin, aspirin and warfarin. At present, the clinical application of low molecular weight heparin is the most, and the effect is the most accurate. This study compared the efficacy and safety of three commonly used anticoagulants such as aspirin, LMWH and Rivaroxaban in preventing VTE after hip and knee arthroplasty, so as to provide a theoretical basis for selecting suitable anticoagulant drugs in clinic...

Cancer patients may experience nonvalvular atrial fibrillation (AF) as a manifestation of cardiotoxicity. AF may be a direct effect of a neoplasm or, more often, appear as a postsurgical complication, especially after thoracic surgery. AF may also develop as a consequence of anticancer therapy (chemotherapy or radiotherapy), a condition probably underestimated. Cancer patients with AF require a multidisciplinary approach involving oncologists/hematologists, cardiologists, and coagulation experts. An echocardiogram should be performed to detect possible abnormalities of left ventricular systolic and diastolic function, as well as left atrial dilation and the existence of valvular heart disease, to determine pretest probability of sinus rhythm restoration, and identify the best treatment...

Background: Venous thromboembolism (VTE) is a major complication after lower-limb arthroplasty that increases costs and reduces patient's quality of life. Using anticoagulants for 10-35 days following arthroplasty is the standard prophylaxis, but its cost-effectiveness after accounting for bleeding complications remains unproven. Methods: A comprehensive, clinical model of VTE was created using the incidences, clinical effects (including bleeding), and costs of VTE and prophylaxis from randomized controlled trials, meta-analyses, and large observational studies...

RATIONALE: Acute pulmonary embolism (APE) as a life-threatening illness may present with a wide range of manifestations. APE was diagnosed using computed tomographic pulmonary angiography (CTPA); however, transthoracic echocardiography (TTE) can reveal hemodynamic status. Early thrombolysis is the most effective therapy for the treatment of massive pulmonary embolism. PATIENTS CONCERNS: Herein, we report a case of high-risk APE with a wide range of manifestations, including chest pain, dyspnea, low-blood pressure, and syncope...

Adhesion of acute promyelocytic leukemia (APL) cells to endothelial cells (EC) is among the mechanisms of the APL-associated coagulopathy, responsible for early hemorrhagic deaths in affected patients. We compared the effects of dalteparin and enoxaparin, two low-molecular-weight heparins (LMWH), and unfractionated heparin (UFH), on APL NB4 adhesion to micro- (HMEC-1) and macro-vascular EC (HUVEC), in resting and interleukin-1β (IL-1β)-stimulated conditions. The heparin effect on EC adhesion molecule (ICAM-1, VCAM-1, E-selectin) expression was also assessed...

OBJECTIVE: This study sought to determine whether there is practice variation in the treatment and prevention of acute venous thromboembolism (VTE) in pregnant patients, potentially to prioritize future studies. BACKGROUND: The risk of VTE during pregnancy is five-fold that of the non-pregnant state. Guidance is often lacking for the treatment and prophylaxis of VTE because there are few RCTs. METHODS: The study used a cross-sectional study design using a self-administered electronic questionnaire consisting of 11 case scenarios that were sent to hematologists, maternal-fetal medicine specialists, obstetricians and gynaecologists, and internal medicine specialists across Canada...

Venous thromboembolism (VTE) occurs in 10-20%% of patients with cancer and is associated with significant mortality and morbidity in these patients. The current standard of care recommended by international guidelines is to use low-molecular-weight heparin (LMWH) for 6months for the management of cancer-associated thrombosis (CAT), which is based on evidence from randomized controlled trials demonstrating that LMWH significantly reduced the risk of recurrent VTE compared with vitamin K antagonists. However, patients with CAT have a high risk of VTE recurrence of up to 20% despite receiving anticoagulation...
