Meta Analysis Comparative StudyOral direct factor Xa inhibitor versus enoxaparin for thromboprophylaxis after hip or knee arthroplasty: Systemic review, traditional meta-analysis, dose-response meta-analysis and network meta-analysis.
To analyze the efficacy and safety of direct factor Xa inhibitors for thromboprophylaxis after total hip or knee replacement. To delineate the dose response effect of direct factor Xa inhibitors. To compare the efficacy between any two direct factor Xa inhibitors. ⋯ Direct oral factor Xa inhibitors are more effective to prevent venous thromboembolism after total hip or knee replacement. Their anticoagulant effect was not necessarily compromised with a higher bleeding risk. Rivaroxaban, apixaban and edoxaban showed a better anticoagulant effect, as compared with enoxaparin. Rivaroxaban had a higher bleeding rate, while apixaban and edoxaban did not show significantly higher bleeding risks.

Role of blood transfusion product type and amount in deep vein thrombosis after cardiac surgery.
Postoperative deep vein thrombosis (DVT) is associated with significant morbidity. Even with maximal thromboprophylaxis, postoperative DVT is present in 10% of cardiac surgery patients, and is linked to receiving transfusion. We hypothesized that the incidence of DVT varies with the transfused blood product type, and increases with transfusion dose. ⋯ RBC transfusion is associated with increased risk of DVT after cardiac surgery in a dose-dependent fashion that is exacerbated when accompanied with FFP. Postoperative screening diagnostic DVS are warranted in this transfused, high risk for DVT population to facilitate timely therapeutic intervention.

Activated prothrombin complex concentrate (FEIBA®) for the treatment and prevention of bleeding in patients with acquired haemophilia: A sequential study.
Despite anti-haemorrhagic therapy with proper doses of activated prothrombin complex concentrate (aPCC, Feiba®), patients with acquired haemophilia A (AHA) have a considerable risk of recurrent bleeding complications. Evidence in support of the benefit-to-risk ratio of prevention strategies with the use of lower doses of aPCC following the end of the initial treatment period is scarce and inconclusive. We report our experience in the management of 18 consecutive patients with AHA admitted to two Haemophilia centres in Italy. ⋯ We observed six relapses of bleeding in patients in whom aPCC was confined to the treatment of the qualifying bleeding episode, and none in patients to whom lower doses were administered until the pre-specified decrease in the titre of FVIII inhibitor was achieved. No patients experienced thrombotic complications during the study period. Prolonging the treatment with lower doses of aPCC beyond the initial phase in patients with AHA in whom the titre of FVIII inhibitor is still high is likely to safely prevent further bleeding complications.
