    The Effect of Salsalate Therapy on Endothelial Function in a Broad Range of Subjects
    (Blackwell Publishing Ltd, 2014) Nohria, Anju; Kinlay, Scott; Buck, J. Stewart; Redline, Whitney; Copeland‐Halperin, Robert; Kim, Sora; Beckman, Joshua A.
    Background: Inflammation is fundamental to the development of atherosclerosis. We examined the effect of anti‐inflammatory doses of salicylate on endothelium‐dependent vasodilation, a biomarker of cardiovascular risk, in a broad range of subjects. Methods and Results: We performed a randomized, double‐blind, placebo‐controlled crossover trial evaluating the effects of 4 weeks of high‐dose salsalate (disalicylate) therapy on endothelium‐dependent flow‐mediated and endothelium‐independent vasodilation. Fifty‐eight subjects, including 17 with metabolic syndrome, 13 with atherosclerosis, and 28 healthy controls, were studied. Among all subjects, endothelium‐dependent flow‐mediated vasodilation decreased after salsalate compared with placebo therapy (P=0.01), whereas nitroglycerin‐mediated, endothelium‐independent vasodilation was unchanged (P=0.97). Endothelium‐dependent flow‐mediated vasodilation after salsalate therapy was impaired compared with placebo therapy in subjects with therapeutic salicylate levels (n=31, P<0.02) but not in subjects with subtherapeutic levels (P>0.2). Conclusions: Salsalate therapy, particularly when therapeutic salicylate levels are achieved, impairs endothelium‐dependent vasodilation in a broad range of subjects. These data raise concern about the possible deleterious effects of anti‐inflammatory doses of salsalate on cardiovascular risk. Clinical Trial Registration URL: www.clinicaltrials.gov.

    Advanced nodal stage predicts venous thromboembolism in patients with locally advanced non-small cell lung cancer
    (Elsevier BV, 2016) Li, Richard Jay; Hermann, Gretchen; Baldini, Elizabeth; Chen, Aileen; Jackman, David M; Kozono, David; Nguyen, Paul; Nohria, Anju; Powell, Graham; Mak, Raymond
    Objectives: Patients with non-small cell lung cancer (NSCLC) are known to be at high risk for venous thromboembolism (VTE), but previous studies have not specifically analyzed locally advanced disease. We performed a retrospective VTE risk analysis in a cohort of locally advanced NSCLC treated with definitive intent including radiation therapy. Materials and Methods: The cohort consisted of 629 patients with stage II-III NSCLC treated at a single institution from January 2003 to December 2012. All patients received treatment with curative intent, including radiation therapy. Fine and Gray’s competing-risks regression model, accounting for death and distant metastasis as competing risks, was used to identify significant predictors of VTE risk, and cumulative incidence estimates were generated using the competing-risks model. Results and Conclusion: At a median follow-up of 31 months, 127 patients developed a VTE, with 80% of events occurring in the first year after treatment initiation. 1-year and 3-year overall cumulative incidence estimates were 13.5% and 15.4%, respectively. On univariate analysis, stage IIIB and N3 nodal disease were associated with increased VTE risk. In the final multivariable model, N3 nodal disease was associated with increased VTE risk (Hazard ratio 1.64; 95% CI 1.06-2.54; p=0.027). In conclusion, patients with locally advanced NSCLC are at high risk for VTE, especially in the first year after treatment initiation, with a 1-year cumulative incidence of 13.5%. N3 nodal staging was associated with significantly higher VTE risk compared to N0-N2 staging.
