Diagnostic Blood Biomarkers for Acute Pulmonary Embolism: A Systematic Review.

(1) Background: The current diagnostic algorithm for acute pulmonary embolism (PE) is associated with the overuse of CT pulmonary angiography (CTPA). An additional highly specific blood test could potentially lower the proportion of patients with suspected PE that require CTPA. The aim was to summarize the literature on the diagnostic performance of biomarkers of patients admitted to an emergency department with suspected acute PE.

Abdominal obesity and the risk of venous thromboembolism among women: a potential role of interleukin-6.

Background: Abdominal obesity increases the risk of venous thromboembolism (VTE). It remains unclear to what extent inflammation contributes to the risk of VTE from abdominal obesity. Our objectives were to investigate the association between abdominal obesity and VTE and the effect of inflammation on this association in a case-control study comprised of women.

Polymorphisms in antithrombin and in tissue factor pathway inhibitor genes are associated with recurrent pregnancy loss.

Recurrent pregnancy loss (RPL) is a multifactorial condition. The effect of antithrombin (SERPINC1), protein C (PROC), thrombomodulin (THBD) and tissue factor pathway inhibitor (TFPI) single nucleotide polymorphisms (SNPs) on the risk of RPL is thus far unknown. Our objective was to determine the association of SNPs in the above mentioned genes with RPL.

Autologous stem cell transplantation improves quality of life in economically challenged, Brazilian multiple myeloma patients.

Objectives: 1) To characterize the impact of multiple myeloma on the quality of life of patients treated in two public institutions in São Paulo State, Brazil, using a generic Short Form 36 Health Survey and a questionnaire specific for oncologic patients (QLQ-C30) upon diagnosis, after the clinical treatment, and at day +100 after autologous stem cell transplantation; 2) to evaluate whether autologous stem cell transplantation can improve the quality of life of our economically challenged population aside from providing a clinical benefit and disease control.

Methods: We evaluated 49 patients with multiple myeloma (a total of 70 interviews) using the two questionnaires. The scores upon diagnosis, post-treatment/pre-autologous stem cell transplantation, and at D+100 were compared using ANOVA (a comparison of the three groups), post hoc tests (two-by-two comparisons of the three groups), and paired t-tests (the same case at two different times).

Performance of Platelin LS and dilute Russell's viper venom for the screening of lupus anticoagulant in patients with venous thromboembolism.

Lupus anticoagulant is associated with thrombosis and pregnancy morbidity, and its detection is of major clinical importance. The nature and concentration of phospholipids strongly influence the sensitivity of activated partial thromboplastin time (aPTT) reagents to lupus anticoagulant. We investigated the ability of Platelin LS, an aPTT reagent, to screen lupus anticoagulant among 94 patients with venous thromboembolism by comparing its performance with the dilute Russell viper venom time (dRVVT).

Cerebral venous thrombosis and hepatitis: case report.

Among the many infective causes of cerebral venous thrombosis (CVT), viral hepatitis is been regarded as a rare associated condition. We report on a 56-years-old man presenting CVT associated with hepatitis B and C coinfections outlining probable pathogenic mechanisms. We suggest that virus B and C serology should be performed in the cases of cerebral venous thrombosis with unknown etiology.
