Multicenter Study Observational StudyLow drug levels and thrombotic complications in high-risk atrial fibrillation patients treated with direct oral anticoagulants.
Essentials Direct oral anticoagulants (DOACs) do not require laboratory monitoring currently. DOAC specific measurements were performed at trough in patients with atrial fibrillation. Patients who developed thromboembolic events showed lower DOAC plasma levels. This study supports the concept of measuring DOAC levels at steady state.

Comparative StudyAge-adjusted D-dimer cut-off leads to more efficient diagnosis of venous thromboembolism in the emergency department: a comparison of four assays.
Essentials Age-adjusted D-dimer cut-offs decrease the false positives in the elderly. Four D-dimer assays were compared in venous thromboembolism outpatients in an emergency ward. Age-adjusted cut-off resulted in improved specificity with maintained sensitivity for all assays. There was a substantial decrease in false positive results, especially in the older population.

Risk of early-onset breast cancer among women exposed to thoracic computed tomography in pregnancy or early postpartum.
Essentials Tests for pulmonary embolism expose women to low-dose radiation. 5859 pregnancies had a thoracic computed tomography (T-CT) vs. 1.3 million who did not. The adjusted hazard ratio for breast cancer was 1.17 (95% confidence interval 0.80-1.70). The long-term risk of breast cancer among women who had a T-CT remains unknown.

Variation of renal function over time is associated with major bleeding in patients treated with direct oral anticoagulants for atrial fibrillation.
Essential In patients on treatment with direct anticoagulants (DOACs) variation of renal function is common. The effect of variations of renal function over time on major bleeding is not well defined. Variation of renal function over time is an independent predictor of major bleeding. Identifying conditions associated with variation of renal function may increase safety of DOACs.
