Comparing Anticoagulation Strategies for Venous Thromboembolism Associated With Active Cancer: A Systematic Review and Meta-Analysis.

Background: Current guidelines recommend several direct oral anticoagulant agents (DOACs) equally for managing cancer-associated venous thromboembolism (VTE). Objectives: The aim of this study was to assess the efficacy and safety of DOACs in patients with active cancer. Methods: Literature searches were conducted in PubMed, Embase, and Cochrane Central in November 2022. Randomized controlled trials investigating anticoagulation strategies (vitamin K antagonists, parenteral anticoagulation [eg, low-molecular weight heparin], and DOACs) for VTE in patients with active cancer were identified for network meta-analysis. The outcomes included recurrent VTE, recurrent pulmonary embolism, recurrent deep venous thrombosis, major bleeding, clinically relevant nonmajor bleeding (CRNMB), and a composite outcome of major bleeding or CRNMB. Pooled HRs and 95% CIs were estimated using either the HR or relative risk provided from each study. Random-effects models were used for all the analyses. Results: Seventeen randomized controlled trials involving 6,623 patients with active cancer were included. No significant differences were found among the DOACs for efficacy outcomes (recurrent VTE, pulmonary embolism, and deep venous thrombosis). In terms of major bleeding, apixaban was similarly safe compared with dabigatran and rivaroxaban but was associated with a decreased risk compared with edoxaban (HR: 0.38; 95% CI: 0.15-0.93). Regarding CRNMB, edoxaban was similarly safe compared with apixaban but was associated with a decreased risk compared with rivaroxaban (HR: 0.31; 95% CI: 0.10-0.91). Compared with parenteral anticoagulation, apixaban was associated with a reduced risk for recurrent VTE (HR: 0.60; 95% CI: 0.38-0.93) without increasing bleeding, edoxaban was associated with an increased risk for major bleeding or CRNMB (HR: 1.35; 95% CI: 1.02-1.79), and rivaroxaban was associated with an increased risk for CRNMB (HR: 3.76; 95% CI: 1.43-9.88). Conclusions: DOACs demonstrate comparable efficacy but exhibit different safety profiles. Apixaban may confer an antithrombotic benefit without an increased risk for bleeding, distinguishing it from other contemporary anticoagulation strategies in patients with active cancer and VTE.

Benefits of an Early Mobility Program for Hospitalized Patients With Cancer.

PURPOSE: Patients with cancer are often hospitalized with complications from cancer and cancer treatment. Many experience a decline in physical functioning, including loss of mobility, which likely contributes to increased length of stay (LOS) and increased readmissions. We aimed to determine whether a mobility program would improve quality of care and decrease health care utilization. METHODS: We implemented a mobility aide program on an oncology unit in a large academic medical center for all patients without bedrest orders between October 1, 2018, and February 28, 2021. The program consisted of nursing evaluation using the Activity Measure for Post-Acute Care (AMPAC), an ordinal scale ranging from bed rest to ambulating ≥ 250 feet, to quantify mobility. Plan of care was determined in a multidisciplinary manner with physical therapy (PT), nursing, and a mobility aide, who is a medical assistant with enhanced rehabilitation training. Patients were then mobilized two times per day 7 days a week. Using descriptive statistics and mixed effects logistic regression, we evaluated the programs impact on LOS, readmissions, and changes in mobility during this time period compared with the 6-month interval before implementation. RESULTS: A total of 1,496 hospitalized patients were identified. The odds of hospital readmission within 30 days of discharge was significantly less for those who received the intervention (OR, 0.53; 95% CI, 0.37 to 0.78; P = .001). The odds ratio (OR) of having a final AMPAC score at or above the median was significantly higher for those who received the intervention (OR, 1.60; 95% CI, 1.04 to 2.45; P < .05). There was no significant difference in LOS. CONCLUSION: Use of this mobility program resulted in a significant decrease in readmissions and maintained or improved patients' mobility. This demonstrates that non-PT professionals can effectively mobilize hospitalized patients with cancer, thereby decreasing the burden on PT and nursing resources. Future work will evaluate the sustainability of the program and evaluate association with health care costs.

Approach to a patient with "double refractory" chronic lymphocytic leukemia: "Double, double toil and trouble" (Shakespeare).

As patients continue to live longer with chronic lymphocytic leukemia, it has become evident that there is an unmet treatment need for patients who have progressed on multiple lines of therapy. In this article, we attempt to define the "double refractory" patient as resistant to both Bruton's tyrosine kinase inhibitors (BTKi) and venetoclax for which prognosis is poor and there remains no standard of care. We further examine the mechanism of resistance to these targeted agents and discuss the current landscape for managing this patient population. Finally, we explore data supporting promising new agents, including non-covalent BTKi, chimeric antigen receptor T cells, and additional classes of agents currently in development.

The effect of post mastectomy radiation therapy on survival in breast cancer patients with N1mic disease.

BACKGROUND: The role of post mastectomy radiation therapy (PMRT) in patients with N1mic breast cancer has not been well defined. A retrospective analysis was performed using the SEER database to evaluate the impact of PMRT on survival in patients with N1mic breast cancer. MATERIALS AND METHODS: Women with T1-T2, N1mic, M0 breast cancer who had undergone mastectomy were analyzed. Descriptive statistics were calculated for all variables. Univariate analysis to assess for differences in survival with respect to covariates was performed using the log rank test while multivariate analysis was performed with Cox proportional hazards regression. Sub-cohort analysis with propensity score matching was used to assess differences in survival among patients undergoing PMRT vs no PMRT. Comparisons were considered statistically significant at P < 0.05. RESULTS: Among 5878 patients, 1202 (20%) underwent PMRT. On univariate analysis, PMRT was a significant predictor of CSS, but not OS. There was no difference in either OS or CSS between the PMRT vs no PMRT groups on multivariate Cox regression analysis and after propensity score matching. CONCLUSIONS: Among patients with T1-T2, N1mic, M0 breast IDC from the SEER database, there was no difference in either OS or CSS among patients who underwent PMRT vs no PMRT. These results suggest that PMRT does not impact survival among breast cancer patients with N1mic disease. However, additional prospective studies with longer follow up are necessary for further evaluation.

Impact of food allergy on food insecurity and health literacy in a tertiary care pediatric allergy population.

BACKGROUND: Food insecurity (FI), limited availability of or access to nutritional foods, is linked to poor child/caregiver health. We examined FI in food-allergic and non-food-allergic children to determine whether dietary limitations associated with food allergy increases risk of FI. METHODS: Food-allergic and non-food-allergic children (1-17 years) were recruited from Arkansas Children's Hospital allergy/asthma clinics. The USDA Food Security Survey, the Newest Vital Sign Health Literacy (HL) questionnaire, and the Food Allergy Impact Scale QOL survey were administered. Logistic regression and analysis of covariance models were utilized for data analysis. RESULTS: Subjects (n = 650) included 325 food-allergic and 325 non-food-allergic children. Overall rate of FI was 21.5% (food allergic 22.2% and non-food allergic 20.9%) with no significant difference in the prevalence of FI between groups (OR = 1.30; 95% CI 0.86-1.96; P = 0.21). FI was increased in households of children with both milk and egg allergy when compared to those without food allergy and those with single food allergy (OR = 2.5; 95% CI 1.4-4.6; P = 0.003). Mean HL rates were higher in the food-secure vs food-insecure groups (mean diff = 0.31; 95% CI 0.03-0.59; P = 0.03). Among food-allergic children, QOL was better in the food-secure vs food-insecure group (mean diff = 0.61; 95% CI 0.002-1.23; P = 0.049). CONCLUSION: Food allergy to milk and egg was associated with increased risk of household FI. Food-insecure participants had lower HL than their food-secure counterparts. Further work is needed to define risks associated with FI among food-allergic children to improve screening and management strategies.
