    Send us a textIn this episode of CLOT Conversations, we sit down with Dr. Marc Carrier to explore a groundbreaking study published in the New England Journal of Medicine on reduced-dose apixaban for cancer-associated venous thromboembolism (VTE). Dr. Carrier breaks down the study's findings, which suggest that a lower dose of apixaban after six months of treatment is just as effective in preventing clot recurrence — and significantly safer in terms of bleeding risk. Tune in for expert insights on how this data could shift clinical practice and improve outcomes for patients living with cancer.Reference:Mahé I, Carrier M, Mayeur D, Chidiac J, Vicaut E, Falvo N, Sanchez O, Grange C, Monreal M, López-Núñez JJ, Otero-Candelera R.

    This podcast episode features Dr. Barbara Gunka and Dr. Siraj Mithoowani discussing their research on how bariatric surgery affects direct oral anticoagulants (DOACs).Bariatric surgery is increasingly used to fight obesity-related health problems. However, these patients often need DOACs to prevent blood clots due to surgery and obesity.The concern is that bariatric surgery might change how the body absorbs DOACs. This could make the medications less effective. There's limited data on long-term DOAC use after bariatric surgery.Dr. Gunka and Dr. Mithoowani's study investigated DOAC levels in patients after bariatric surgery. They looked at patients who received any type of bariatric surgery, took a DOAC for any reason, and had their DOAC levels measured afterwards.Tune in to hear the full discussion about the study's findings and their implications for DOAC use after bariatric surgery.Reference:Gunka, B., Mackenzie, D., Hughes, T., Sardo, L., Bayadinova, J., Siegal, D.

    In Season 2, Episode 2 of CLOT Conversations from Thrombosis Canada, Dr. Tzu-Fei Wang, an associate professor and hematologist, discusses a recent study titled "The prevalence of relevant drug-drug interactions and associated clinical outcomes in patients with cancer-associated thrombosis on concurrent anticoagulation and anticancer or supportive care therapies." The study aimed to investigate drug-drug interactions (DDIs) between anticoagulants and other medications in cancer patients and their impact on clinical outcomes.High Risk of DDIs: The study found that approximately 41% of cancer patients on anticoagulation therapy had relevant drug-drug interactions, particularly with antidepressants and certain other medications.Overall, the study highlights the importance of assessing and managing drug-drug interactions in cancer patients receiving anticoagulation therapy, while also suggesting that not all DDIs necessarily lead to adverse clinical outcomes. Collaborative efforts and larger data sets are needed to better understand and address this complex issue.Reference: Wang TF, Hill M, Mallick R, Chaudry H, Unachukwu U, Delluc A, Carrier M.
