Clinical significance of anti-domain 1 β2-glycoprotein I antibodies in antiphospholipid syndrome.
Antiphospholipid syndrome (APS) is characterized by the presence of circulating antiphospholipid antibodies (aPL) in patients with thrombosis and/or pregnancy morbidity. In APS patients anti-domain 1 β2-glycoprotein I (anti-D1 β2GPI) IgG antibodies correlate strongly with thrombosis and to the lesser extent, with pregnancy complications. The aim of this study was to assess clinical utility of the anti-D1 β2GPI antibodies in the diagnosis and risk stratification of antiphospholipid syndrome. ⋯ Anti-D1 IgG antibodies did not add diagnostic power to the standard laboratory aPL tests as assessed by this retrospective study. A true clinical significance of anti-D1 antibodies in thrombotic risk stratification of aPL positive patients will require a properly designed clinical prospective trials.

Review Meta Analysis Comparative StudyComparison of intravenous versus topical tranexamic acid in primary total hip and knee arthroplasty: An updated meta-analysis.
The appropriate route for administering tranexamic acid in primary total hip (THA) and knee arthroplasty (TKA) remains controversial. The purpose of this meta-analysis was to compare the efficacy and safety of topical or intravenous tranexamic acid. ⋯ The available evidence indicates similar transfusion requirements and safety for topical and intravenous tranexamic acid in THA and TKA. However, intravenous injection seems to be associated with a smaller maximum drop in hemoglobin.

ReviewOral contraception and menstrual bleeding during treatment of venous thromboembolism: Expert opinion versus current practice: Combined results of a systematic review, expert panel opinion and an international survey.
The optimal management of oral contraception and menstrual bleeding during treatment of venous thromboembolism (VTE) is largely unknown. We aimed to elicit expert opinion and compare that to current practice as assessed by a world-wide international web-based survey among physicians. ⋯ International experts' opinions on handling of contraceptives and management of anticoagulant-associated abnormal uterine bleeding in female VTE patients are divergent and management in clinical practice is heterogeneous. There is a great need of further studies on these topics.

Predictors of postoperative bleeding in children undergoing cardiopulmonary bypass: A preliminary Italian study.
Several characteristics such as demographics, pre-existing conditions, surgical procedure, perioperative coagulopathy may predispose children undergoing cardiopulmonary bypass (CPB) to bleeding complications. As yet, studies on risk factors for postoperative bleeding have brought mixed results. The purpose of our study was therefore to retrospectively evaluate the parameters able to predict postoperative bleeding in a group of consecutive children undergoing cardiac surgery involving CPB. ⋯ Although preliminary, our study identified younger age, lower postoperative platelet count and higher D-dimer plasma levels as possible risk factors for postoperative bleeding. As for coagulation parameters, our results suggested consumptive coagulopathy might cause a strong predisposition to postoperative bleeding in children. Large-scale prospective studies would provide insight into the early diagnosis and treatment of CPB-related coagulopathies.

Inferior vena cava filters in patients with cancer and venous thromboembolism (VTE) does not improve clinical outcomes: A population-based study.
There are few studies that have determined clinical outcomes following inferior vena cava filter (IVCF) insertion in cancer patients hospitalized for acute deep-vein-thrombosis (DVT) or pulmonary embolism (PE). ⋯ We conclude that in this population-based study, approximately 20% of cancer patients with acute VTE received an IVCF, but only 21% of these had an indication for IVCF use. Overall, IVCF use provided neither a short-term survival benefit nor a reduction in risk of recurrent PE, but IVCF use was associated with a higher risk of recurrent DVT.
