ABSTRACT

Direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists, mostly warfarin, for the main indications for oral anticoagulation, prevention and treatment of venous thromboembolism, and prevention of embolic stroke in atrial fibrillation. While DOACs offer practical, fixed-dose anticoagulation in many patients, specific restrictions or contraindications may apply. DOACs are not sufficiently effective in high-thrombotic risk conditions such as antiphospholipid syndrome and mechanical heart valves. Patients with cancer-associated thrombosis may benefit from DOACs, but the bleeding risk, particularly in those with gastrointestinal or urogenital tumors, must be carefully weighed. In patients with frailty, excess body weight, and/or moderate-to-severe chronic kidney disease, DOACs must be cautiously administered and may require laboratory monitoring. Reversal agents have been developed and approved for life-threatening bleeding. In addition, the clinical testing of potentially safer anticoagulants such as factor XI(a) inhibitors is important to further optimize anticoagulant therapy in an increasingly elderly and frail population worldwide. Expected final online publication date for the Annual Review of Pharmacology and Toxicology, Volume 64 is January 2024.

Venous thromboembolism prophylaxis practices for patients with sickle cell disease prior to and during the COVID-19 pandemic

Blood Coagul Fibrinolysis. 2023 Sep 21. doi: 10.1097/MBC.0000000000001250. Online ahead of print.

ABSTRACT

Patients with sickle cell disease (SCD) are predisposed to a hypercoagulable state due to alterations in the coagulation system. Despite concern for the development of venous thromboembolism (VTE) in this population, there are no standardized guidelines for routine thromboprophylaxis. The objective of this study was to assess thromboprophylaxis practices of adult and pediatric treaters of SCD before and during the coronavirus disease of 2019 (COVID-19) pandemic. A cross-sectional electronic survey was distributed to pediatric and adult hematology oncology practitioners through seven SCD-specific interest groups between May 29, 2020, and July 13, 2020. Of 93 total responses, 14% (N = 13) reported they only treat patients more than 21 years old; 38.7% (N = 36) only treat patients 0-21 years old and 47.3% (N = 44) reported they treat both. Our study showed that before the COVID-19 pandemic, 96% of adult practitioners would recommend pharmacologic thromboprophylaxis, mechanical thromboprophylaxis or both for hospitalized adults with thromboprophylaxis, but only 76% of pediatric treaters would recommend any thromboprophylaxis in hospitalized children (P < 0.0001), with 24% of pediatric treaters choosing no thromboprophylaxis at all. During the COVID-19 pandemic, pharmacologic thromboprophylaxis specifically was recommended for adults by 94% of treaters and for pediatric patients by 76% of treaters. These findings suggest that despite the lack of evidence-based thromboprophylaxis guidelines in adults and children with thromboprophylaxis, subspecialty treaters routinely provide pharmacologic thromboprophylaxis in their adult patients and will modify their practice in pediatric patients who are considered at a high risk for VTE.

Exercise as Medicine in Cardio-Oncology: Reducing Health Disparities in Hispanic and Latina Breast Cancer Survivors

Curr Oncol Rep. 2023 Sep 16. doi: 10.1007/s11912-023-01446-w. Online ahead of print.

ABSTRACT

PURPOSE OF REVIEW: This review aims to access the current state of the evidence in exercise as medicine for cardio-oncology in Hispanic and Latina breast cancer survivors and to provide our preliminary data on the effects of supervised aerobic and resistance training on cardiovascular disease (CVD) risk in this population.

RECENT FINDINGS: Breast cancer survivors have a higher risk of CVD; particularly Hispanic and Latina breast cancer survivors have a higher burden than their White counterparts. Exercise has been shown to reduce CVD risk in breast cancer survivors; however, evidence in Hispanic and Latina breast cancer survivors is scarce. Our review highlights a clear need for exercise oncology clinical trials in Hispanic and Latina breast cancer survivors targeting CVD risk factors. Moreover, our exploratory results highlight that 16 weeks of aerobic and resistance training may reduce the 10-year risk of developing CVD by 15% in Hispanic and Latina breast cancer survivors.
