Incidence and risk factors for venous thromboembolism in patients with acute spinal cord injury: A retrospective study.
The true incidence of venous thromboembolism (VTE) in patients with acute spinal cord injury (SCI) is unclear. There are limited data on the risk factors associated with VTE in patients with an acute SCI. ⋯ Symptomatic VTE is a frequent complication in patients with acute SCI. Age and presence of other sites of injuries along with SCI were independent risk factors for symptomatic VTE.

Early thrombin formation capacity in trauma patients and association with venous thromboembolism.
Incidence of venous thromboembolism (VTE) in adult trauma patients is high despite mechanical and pharmacologic prophylaxis. We hypothesized that thrombin formation capacity as measured by calibrated automated thrombogram (CAT) is increased early in hospitalization and is associated with the development of VTE.

Antithrombin supplementation and risk of bleeding in patients with sepsis-associated disseminated intravascular coagulation.
Although antithrombin is commonly used for the treatment of sepsis-associated disseminated intravascular coagulation (DIC) in Japan, the factors influencing the incidence of bleeding complications have not been sufficiently studied. The purpose of this survey was to identify the factors that predict clinically relevant bleeding in patients receiving antithrombin for DIC. ⋯ A higher dose of antithrombin or the concomitant use of other anticoagulants were not associated with bleeding events. On the other hand, sustained DIC lasting more than one week was associated with an increased risk of bleeding in patients with sepsis-associated DIC.

LetterEvaluation of US prescription patterns: Are treatment guidelines for cancer-associated venous thromboembolism being followed?
Venous thromboembolism (VTE) is a common complication of cancer. Clinical practice guidelines recommend low-molecular-weight heparin (LMWH) for treatment of cancer-associated VTE, but it is unclear how frequently these are followed. This study assessed anticoagulation treatment patterns for VTE in newly diagnosed cancer patients in the United States. ⋯ Warfarin was the most utilized anticoagulant for cancer-associated VTE despite guideline recommendations for LMWH. More patients remained on oral versus injectable agents, which may be related to self-injection burden and costs.

Correlative analysis of nanoparticle tracking, flow cytometric and functional measurements for circulating microvesicles in normal subjects.
Circulating microvesicles (MV) can be analysed using a number of different techniques. The aim of this study was to evaluate the correlation between functional procoagulant based assays including thrombin generation, factor Xa activation test (XaCT), and phosphatidylserine factor Xa-activity by ELISA with optical MV enumeration by flow cytometry and nanoparticle tracking analysis. ⋯ Thrombin generation and flow cytometry for phosphatidylserine or tissue factor expressing MV correlate well as markers for procoagulant activity. A combination of optical or non-optical enumeration as well as functional methods may be required for a complete profiling of circulating MV.
