Thromboelastography identifies hypercoagulablilty and predicts thromboembolic complications in patients with prostate cancer.
Cancer patients are at higher risk for thromboembolism compared to the normal population. This may be related to tumour burden and/or enhanced by systemic therapy. While there is ample evidence regarding venous thromboembolism, systematic studies investigating arterial thrombotic events are scarce. ⋯ Seven of the 22 hypercoagulable patients (31.8%) developed one or more thromboembolic events over 12months follow up period. The data in this pilot study show that PCa patients are hypercoagulable, particularly those with advanced disease on ADT and that this hypercoagulability can be identified by TEG. While this needs to be verified in a larger study, the data indicate TEG may aid in thrombosis risk stratification and determining the subsequent need for anticoagulant prophylaxis in PCa patients.

Comparative StudyIncidence of thrombosis in children with tunneled central venous access devices versus peripherally inserted central catheters (PICCs).
The recent proliferation of deep vein thrombosis in children has been attributed to the increased use of central venous catheters, specifically tunneled lines and peripherally inserted central catheters. A formal comparison of the incidence rate for deep vein thrombosis between tunneled lines and peripherally inserted central catheters has not been undertaken. ⋯ Despite the relative ease and simplicity of use of peripherally inserted central catheters leading to a substantial rise in their use, this study demonstrates that such lines pose a substantial risk for venous thrombosis and no difference in incidence was detected between such lines and tunneled lines.

Surfactant impairs coagulation in-vitro: a risk factor for pulmonary hemorrhage?
Pulmonary hemorrhage (PHEM) complicates the hospital course of 3-5% of preterm infants with respiratory distress syndrome (RDS), and bears a high mortality rate. Impaired thrombin generation and poor clot formation in premature neonates affect PHEM severity. ⋯ The presence of surfactant impairs coagulation in-vitro. The risk of PHEM may therefore be greater in extremely premature infants. Future studies are required to assess the clinical significance and relevance of our preliminary findings.
