Characterization of 2 Different Prothrombin Complex Concentrates by Different Hemostatic Assays in an In Vitro Hemodilution Model.
Viscoelastically guided coagulation factor concentrate-based algorithms for the treatment of trauma-induced coagulopathy include the administration of prothrombin complex concentrates (PCCs). However, the exact role of PCC preparations in this context is a matter of debate. Particularly, the ideal diagnostic trigger for their administration and potential differences between heparin-containing and heparin-free preparations remain unclear. We investigated the hypothesis that 2 different PCCs might have distinct influences on in vitro blood coagulation. ⋯ Both PCC preparations (ie, irrespective of heparin content) induced significant elevation of thrombin generation, which was not depicted by conventional coagulation tests or VHA. Our in vitro results suggest that diagnostic assays routinely used to guide PCC administration might not adequately reflect thrombin generation in bleeding patients.

Context Analysis of Continued Citation of Retracted Manuscripts Published in Anesthesiology Journals.
The continued citation of retracted publications from the medical literature is a well-known and persistent problem. We describe the contexts of ongoing citations to manuscripts that have been retracted from a selection of anesthesiology journals. We also examine how bibliographic databases and publisher websites document the retracted status of these manuscripts. ⋯ The frequency of citation of the 15 most cited retracted publications declined in a similar pattern during the 10 years after retraction. Citation of manuscripts retracted from anesthesiology journals remains a common occurrence. Technological innovations and application of standards for handling retracted publications, as suggested by coalitions of researchers across the spectrum of scientific investigation, may serve to reduce the persistence of this error.
