    Patterns of International Normalized Ratio Values Among New Warfarin Patients With Nonvalvular Atrial Fibrillation
    (2016) Schein, Jeffrey R; Wang, Li; Nelson, Winnie W.; Damaraju, Chandrasekharrao, V; Milentijevic, Dejan; Başer, Onur
    Limited information exists regarding the relationship between international normalized ratio (INR) control/stability and the discontinuation of warfarin therapy among patients with nonvalvular atrial fibrillation (NVAF). This study evaluated the association between INR stabilization and warfarin discontinuation and assessed INR patterns before and after INR stabilization among patients (18 years) with NVAF who newly initiated warfarin (Veterans Health Administration datasets; October 1, 2007 through September 30, 2012). Achievement of INR stabilization (3 consecutive in-range therapeutic INR measurements 7 days apart) was examined from warfarin initiation through the end of warfarin exposure. Proportion of time in therapeutic range during warfarin exposure was calculated (Rosendaal method) and categorized as at least 60% or less than 60%. Among 34346 patients, 49.4% achieved INR stabilization (mean time to stabilization, 98 days). Approximately 40% of INR values were out-of-range, even after achieving stabilization. During 30 days following an INR 4.0 or higher, patients had more INR testing than the overall mean (2.51 vs. 1.67 tests). Warfarin discontinuation was 4.2 times more likely among patients without INR stabilization versus those with INR stabilization (P<0.00001). Patients with poor INR control (time in therapeutic range <60%) were 1.76 times more likely to discontinue warfarin within 1 year (P<0.0001). INR stabilization is a better predictor of warfarin discontinuation than poor INR control. Improved approaches are necessary to maintain appropriate anticoagulation levels among patients with NVAF.

    Populism and Income Inequality: Is Income Inequality in Türkiye a Political Choice?
    (Istanbul Univ, 2024) Asfuroğlu, Dila
    The argument that national inequalities are political and thereby driven by political decisions implies that income distribution is not merely an economic phenomenon but also a political one. Hence, this study explores the impact of populist governance on income inequality in T & uuml;rkiye. In doing so, this study addresses whether income inequality in T & uuml;rkiye is a political choice, drawing on economic, social, and political data over the years 20082022. According to the results of the quantitative analysis, the share of income for the working class has fallen, the income gap between the lowest and highest deciles of the working class has narrowed, and the potential for fiscal interventions to reduce income inequality is not realised. In return, the income inequality that existed in 2008 has persisted at the same magnitude over the years. In other words, even if income inequality is not an explicit political choice, the populist governance in T & uuml;rkiye between 2008 and 2022 has chosen not to contribute to the solution to this prevailing inequality.
