INTRODUCTION Patients with cancer have a 7- to 10-fold increased risk of developing venous thromboembolism. Circulating microvesicles could be a useful predictive biomarker for venous thromboembolism in cancer. Validated and standardised techniques that could be used to determine the complete microvesicle phenotype are required. OBJECTIVES These were(More)
Patients with hematological malignancies have a 28-fold increased risk of venous thromboembolism (VTE). Among patients with acute myelogenous leukemia (AML), the 2-year cumulative incidence of VTE is 5.2%. Several studies suggest that microvesicles (MVs) harboring TF may play a role in VTE and disseminated intravascular coagulation (DIC) in acute(More)
Patients with cancer have a seven-fold to 10-fold increased risk of developing venous thromboembolism (VTE). Circulating microvesicles could be a predictive biomarker for VTE in cancer. Thrombin generation assay (TGA) is a useful technique to detect procoagulant activity of microvesicles. However, TGA suffers from a lack of sensitivity due to the presence(More)
INTRODUCTION Extracellular vesicles (EVs) are shed from cells and carry markers of the parent cells. Vesicles derived from cancer cells reach the bloodstream and locally influence important physiological processes. It has been previously shown that procoagulant vesicles are circulating in patients' fluids. These EVs are therefore considered as promising(More)
Extracellular vesicles (EVs) generated during tumourigenesis are thought to play a major role in the hypercoagulant state observed in cancer patients. They exhibit negatively charged phospholipids and tissue factor (TF) that promote coagulation cascade activation. In addition, they contain surface proteins and cytoplasmic molecules, both originating from(More)
BACKGROUND The positive effect of leukocyte- and platelet-rich fibrin (L-PRF) on osteogenesis has been widely described in vitro. However, clinical and preclinical studies are very little and controversial in demonstrating a significant beneficial effect of L-PRF in bone regeneration. PURPOSE The goal of the present study was to compare the potential(More)
Haemostatic complication is common for patients with hematologic malignancies. Recent studies suggest that the procoagulant activity (PCA) of extracellular vesicles (EV) may play a major role in venous thromboembolism and disseminated intravascular coagulation (DIC) in acute leukaemia. To study the impact of EVs from leukaemic patients on thrombin(More)
OBJECTIVES To assess the use of PRF prepared using an optimised protocol in middle ear surgery as a substitute for conventional packing products of animal origin such as collagen derived from porcine skin. METHODOLOGY A retrospective study of 108 patients in whom optimised PRF was used exclusively to pack the external auditory canal or middle ear. The(More)
BACKGROUND Thrombotic effects are possible complications of red blood cell transfusion. The generation and accumulation of procoagulant red blood cell extracellular vesicles during storage may play an important role in these thrombotic effects. The objective of this study was to assess the value of a simple phospholipid-dependent clot-based assay(More)
