Performance of 18F fluoro-2-désoxy-D-glucose positron emission tomography/computed tomography for the diagnosis of venous thromboembolism.
Thrombosis and inflammation are intimately linked. Inflammatory component of venous thromboembolism (VTE) may allow the use of FDG positron emission tomography / computed tomography (FDG PET/CT) in the detection of thrombotic process. Published studies remain limited and contradictory. We aimed at evaluating the performance of FDG PET/CT in the detection of VTE in a population of patients enrolled in a prospective study evaluating FDG PET/CT for cancer screening in etiological assessment of idiopathic VTE. ⋯ FDG PET/CT is not accurate enough for the diagnosis of VTE.

CHA2DS2-VASc and HAS-BLED scores and activated partial thromboplastin time for prediction of high plasma concentration of dabigatran at trough.
Although dabigatran, an oral direct thrombin inhibitor, does not require routine monitoring, high plasma concentration of dabigatran (PDC) at trough level is shown to be a high risk for bleeding in patients with nonvalvular atrial fibrillation (NVAF). As dabigatran prolongs the activated partial thromboplastin time (APTT), we examined relationships of PDC at trough with APTT and clinical features to identify patients at high risk for major bleeding during dabigatran treatment. ⋯ This study provides an important clinical implication for identifying patients at high risk for major bleeding during dabigatran treatment in clinical practice.

Review Meta AnalysisHow safe is acetaminophen use in patients treated with vitamin K antagonists? A systematic review and meta-analysis.
Acetaminophen is a commonly prescribed and over-the-count used drug, and is considered to be the preferred treatment choice for anticoagulated patients requiring analgesic drug therapy. However, observational data have suggested that this drug combination may increase the International Normalized Ratio (INR) values and bleeding events in patients taking Vitamin K antagonists (VKAs). Still, the clinical impact of this putative effect remains unknown. Therefore, we performed a systematic review of randomized controlled trials (RCTs) to estimate the impact of concomitant use of acetaminophen and VKA in the INR measurements ⋯ Acetaminophen is associated with a statistically significant and possible clinically relevant increase in the INR, with a dose dependent relationship. Patients treated concomitantly with VKA and acetaminophen should be monitored more regularly for possible VKA dosage adjustment.

ReviewA systematic review of prothrombin complex concentrate dosing strategies to reverse vitamin K antagonist therapy.
Management of patients with a major bleed while on vitamin K antagonist (VKA) is a common clinical challenge. Prothrombin Complex Concentrates (PCC) provide a rapid reversal of VKA induced coagulopathy. However, a well-defined PCC dosing strategy, especially in emergency setting, is still lacking. ⋯ We found no evidence that one dosing strategy is superior. Future studies should be designed to investigate if body weight and INR are relevant for PCC dosing. In these, we need uniform outcome definitions.

Randomized Controlled TrialMild induced hypothermia: effects on sepsis-related coagulopathy--results from a randomized controlled trial.
Coagulopathy associates with poor outcome in sepsis. Mild induced hypothermia has been proposed as treatment in sepsis but it is not known whether this intervention worsens functional coagulopathy. ⋯ Interim analysis data from an ongoing randomized controlled trial; The Cooling And Surviving Septic shock (CASS) study. Patients suffering severe sepsis/septic shock are allocated to either mild induced hypothermia (cooling to 32-34°C for 24hours) or control (uncontrolled temperature).
