Multicenter StudyClinical features and short term outcomes of patients with acute pulmonary embolism. The Italian Pulmonary Embolism Registry (IPER).
Registries are essential to obtain information on the whole spectrum of patients with pulmonary embolism (PE). The aim of the Italian Pulmonary Embolism Registry (IPER) is to report on demographics, clinical features, management, and outcomes of patients diagnosed with PE in everyday clinical practice. ⋯ Patients with PE have a considerable risk of death during the hospital stay, PE being the most common cause of early mortality.

Treatment responses for disseminated intravascular coagulation in 25 children treated with recombinant thrombomodulin: a single institution experience.
Recombinant thrombomodulin (rTM), which degrades factors Va and VIIIa by activating protein C, has been developed as a new drug for treating disseminated intravascular coagulation (DIC). ⋯ The efficacy of rTM cannot be assessed from the present dataset, due to several limitations such as the small heterogenous patient cohort, and the lack of age- and disease-matched controls. Nevertheless, this case-series remains important in terms of enabling further prospective control studies to evaluate the efficacy of rTM in children.

Validation of the Caprini risk assessment model in Chinese hospitalized patients with venous thromboembolism.
Venous thromboembolism (VTE) occurs frequently in at-risk hospitalized patients, and prophylaxis of VTE is significantly underused. We sought to preliminarily assess the validity of Caprini risk assessment model, a famous individual VTE risk assessment model, in Chinese hospitalized patients with VTE. ⋯ Our study preliminarily suggests that the Caprini risk assessment model is a practical and effective tool to assess the risk of VTE among unselected Chinese inpatients and may also be useful in predicting the risk of VTE recurrence. However, future studies with control group and prospective validation of the model in Chinese inpatients are needed.

Clinical TrialThe effect of total hip/knee replacement surgery and prophylactic dabigatran on thrombin generation and coagulation parameters.
Total hip/knee replacement surgery (THR/TKR respectively) is associated with an increased risk of venous thromboembolism. Dabigatran is recommended as a thromboprophylactic agent post orthopaedic surgery. The aim of this study was to assess the post-operative (Day-1 and Day-2) effect of prophylactic Dabigatran on: the thrombin generation (TG) assay; prothrombin fragment 1.2 (F1.2); thrombin-antithrombin complexes (TAT); D-dimer (D-D); and other coagulation parameters. METHODS AND SAMPLES: Nineteen patients (12 THR, 7 TKR) who received 110 mg dabigatran 4 hours post-operatively, then 220 mg the following day, were recruited. Blood was collected: pre-operatively (Pre-); peri-operatively (Peri-); 19 hours after 110 mg dabigatran (Day-1); and 17 hours after 220 mg dabigatran (Day-2). The TG assay was measured using the Calibrated Automated Thrombogram and a low concentration of tissue factor. Other coagulation parameters measured included activated partial thromboplastin time (APTT), thrombin-time (TT), ecarin-clotting time (ECT) and Hemoclot tests. ⋯ The effect of dabigatran on the TG assay, showed a spurious increase in ETP and Peak-thrombin due to its interference with the TG assay. Dabigatran reduced TAT, but not F1.2, suggesting that thrombin was still being generated after surgery, but was blocked by Dabigatran.
