Multicenter Study Comparative StudyThree-month mortality rate and clinical predictors in patients with venous thromboembolism and cancer. Findings from the RIETE registry.
Patients with venous thromboembolism (VTE), and particularly those with cancer, are at increased risk of recurrences, major bleeding, and short- / medium-term mortality. Data from 35,539 patients (6,075 of these with cancer), presenting with symptomatic VTE in the previous three months and enrolled in the worldwide RIETE registry, were evaluated to assess overall and pulmonary embolism (PE)-related mortality, and their potential predictors, with particular focus on patients with cancer. Overall 3-month mortality in the total RIETE population was 7.9%, and death was considered PE-related in 1.4%. ⋯ According to the findings of our very large, real-world registry, in the three months following an acute episode VTE remains a substantial cause of mortality. Cancer patients are at particular high risk of VTE-related death. Clinical factors predicting a fatal PE identified in this study (cancer, immobility, comorbidities, increasing age, PE at presentation), could be considered for risk stratification scheme for secondary prophylaxis in daily practice.

Renal failure as a risk factor for venous thromboembolism in critically Ill patients: a cohort study.
The relationship between kidney function and venous thromboembolism (VTE) in critically ill patients is not well studied. The main objective of this study was to evaluate this relationship in patients admitted to a medical-surgical intensive care unit (ICU). ⋯ Neither AKI nor ESRD was an independent risk factors for critically ill patients.

Effect of warfarin on intracranial hemorrhage incidence and fatal outcomes.
Avoiding intracranial hemorrhage (ICH) during warfarin therapy is critical but little is known about factors that affect warfarin-related ICH outcomes. We aimed to define the impact of warfarin on ICH incidence rates and to identify baseline clinical characteristics of patients who experienced ICH and factors associated with fatal ICH. ⋯ Although warfarin use increases the rate of incident ICH, other factors impact the risk of fatal ICH, even among anticoagulated patients.

There is now compelling evidence that use of oral contraceptives and postmenopausal hormonal therapies containing various estrogens is associated with a weak, but clinically relevant risk of both arterial and venous thrombosis. The increased risk is related to type and dose of both estrogen and combined progestagen and mode of delivery. Treatment induces mainly subtle changes in individual components of the coagulation and fibrinolytic systems, but the overall effect is the induction of a prothrombotic phenotype. This brief review summarizes some of the mechanisms responsible the prothrombotic effects of such treatment.

The occurrence of venous thromboembolism in cancer patients following major surgery.
Venous thromboembolism (VTE), encompassing deep vein thrombosis (DVT) and pulmonary embolism (PE), is common in cancer patients and surgery is an important risk factor. ⋯ A significant proportion of VTE episodes among surgical patients with cancer are diagnosed after discharge from hospital. This suggests that surgical patients with cancer are at risk for VTE beyond the immediate postoperative period.
