BACKGROUND This study evaluates the effect of hemodilution by various common resuscitation fluids, and the efficacy of activated recombinant factor VII (rFVIIa) on coagulation parameters in human blood in vitro. METHODS Samples from normal healthy volunteers (n = 9) were hemodiluted from 0% to 90% with normal saline, or 0%, 40%, 60%, and 80% with 5% albumin, Hespan, Hextend, normal saline, or...
BACKGROUND Few data exist regarding frequency and predictors of bleeding complications associated with anticoagulant therapy using dabigatran in Japanese patients with atrial fibrillation (AF). METHODS AND RESULTS We retrospectively studied 184 patients with AF who were administered dabigatran from April 2011 to August 2012 in our institution. Twenty-eight patients (15%) developed some type o...
Surgical revascularization of the heart (CABG - coronary artery bypass grafting) is one way of treating coronary heart disease. Bleeding is one of the serious and frequent complications of heart surgery and can result in increased mortality and morbidity. Hemostasis disorder may be secondary consequences of surgical bleeding, preoperative anticoagulant therapy, and the use of cardiopulmonary by...
Page 5, line 14: The authors outline the taking of blood at various time intervals "after argatroban or lepirudin infusion". It is unclear to the reader if this refers to commencement or cessation. In reply: We added the word “initiation” to the sentence, which now reads as: “Before as well as 12, 24, 48 and 72 hours after initiation of argatroban or lepirudin infusion, blood was analysed...” P...
The coagulation cascade and inflammatory process are known to be associated with the pathophysiology of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We retrospectively investigated laboratory values indicating coagulopathy obtained within 24 hr from diagnosis of ALI/ARDS in 79 children who received mechanical ventilation between 2008 and 2009 and their final outcomes....
Rodent ovariectomy is an experimental method to eliminate the main source of sexual steroids. This work explored for the first time the ovariectomy temporal changes induced in the hemostatic coagulation markers: prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen concentration (FIB) along with uterine weight on adult female CD1 mice and Wistar...
The similarity to materials corrosion is invoked to develop a model for phage-infected bacterial lysis based on the statistics of extremes. The importance of cell size, envelope thickness and lysozyme eclipse time on the final probability distribution of lysis is considered. Experiments are suggested to test the model.
This paper proposes a MEMS-based sensor array enabling multiple clot-time tests for plasma in one disposable microfluidic cartridge. The versatile LoC (Lab-on-Chip) platform technology is demonstrated here for real-time coagulation tests (activated Partial Thromboplastin Time (aPTT) and Prothrombin Time (PT)). The system has a reader unit and a disposable cartridge. The reader has no electrical...
BACKGROUND Laboratory tests to assess novel oral anticoagulants (NOACs) are under evaluation. Routine monitoring is unnecessary, but under special circumstances bioactivity assessment becomes crucial. We analyzed the effects of NOACs on coagulation tests and the availability of specific assays at different laboratories. METHODS Plasma samples spiked with dabigatran (Dabi; 120 and 300 μg/L) or...
BACKGROUND A substantial fraction of all American healthcare expenditures are potentially wasted, and practices that are not evidence-based could contribute to such waste. We sought to characterize whether Prothrombin Time (PT) and activated Partial Thromboplastin Time (aPTT) tests of preoperative patients are used in a way unsupported by evidence and potentially wasteful. METHODS AND FINDING...
