Recombinant Human Soluble Thrombomodulin in Sepsis-Induced Coagulopathy: An Updated Systematic Review and Meta-Analysis.
Clinical effectiveness of recombinant human soluble thrombomodulin (rhTM) in sepsis or sepsis-induced coagulopathy remains a matter of dispute. Recently, the Sepsis Coagulopathy Asahi Recombinant LEThrombomodulin (SCARLET) trial, the latest multinational multi-centre phase III randomized controlled trial, was completed. ⋯ Even in this updated review including the latest SCARLET trial, we currently cannot make any declarative judgments about the beneficial effects of rhTM in sepsis-induced coagulopathy, although some favourable effects were suggested.

Review Meta Analysis
Prothrombin complex concentrates versus fresh frozen plasma for warfarin reversal. A systematic review and meta-analysis.
Urgent reversal of warfarin is required for patients who experience major bleeding or require urgent surgery. Treatment options include the combination of vitamin K and coagulation factor replacement with either prothrombin complex concentrate (PCC) or fresh frozen plasma (FFP). However, the optimal reversal strategy is unclear based on clinically relevant outcomes. ⋯ Patients receiving PCC had a lower risk of post-transfusion volume overload compared to FFP (OR 0.27, 95 % CI; 0.13-0.58). There was no statistically significant difference in the risk of thromboembolism following administration of PCC or FFP (OR 0.91, 95 % CI; 0.44-1.89). In conclusion, as compared to FFP, the use of PCC for warfarin reversal was associated with a significant reduction in all-cause mortality, more rapid INR reduction, and less volume overload without an increased risk of thromboembolic events.

Review Meta Analysis
LMWH in the prevention of preeclampsia and fetal growth restriction in women without thrombophilia. A systematic review and meta-analysis.
Placental mediated pregnancy complications such as preeclampsia and fetal growth restriction (FGR) are common, serious, and associated with increased morbidity and mortality. We conducted a systematic review and meta-analysis to determine the effect of treatment with low-molecular-weight heparins (LMWHs) for secondary prevention of these complications in non thrombophilic women. We searched the electronic databases PubMed, Scopus, and Cochrane Library for randomised controlled trials addressing this question. ⋯ From the data available for analysis it appears that the use of Dalteparin is associated with a risk reduction for preeclampsia (p=0.002) and FGR (p<0.001); while Enoxaparin is associated with risk reduction for preeclampsia (p=0.013) but not for FGR (p=0.3). In spite of the small number of studies addressing the research question, and the high variability among them, our meta-analysis found a modest beneficial effect of LMWH for secondary prevention of preeclampsia and FGR. Further studies are needed to address these questions before a definite conclusion can be reached.
