'A Divided Soul'? the Cold War odyssey of O. John Rogge

In 1948 O. John Rogge, a prominent American liberal, was a contender for the Progressive Party's vice-presidential nomination. He was then a man of the Left: an activist in the international peace movement, a champion of radical causes and a defender of organizations deemed subversive by the Department of Justice. In 1951 he persuaded his\ud client to turn government witness in the Rosenberg espionage trial and was converted into 'Rogge the Rat' by his former allies. In tracing this transformation, this paper will argue that Rogge was neither a typical Cold War apostate nor a typical anti-Stalinist intellectual. Instead, his political trajectory was the outcome of a failed attempt to steer global politics away from Cold War dichotomies. The paper will therefore throw new light\ud both on the movement to find a 'third way' between East and West, and on the phenomenon of non-communist Left activism during the early Cold War

Predicting Kidney Failure, Cardiovascular Disease and Death in Advanced CKD Patients

Introduction: Predicting the timing and occurrence of kidney replacement therapy (KRT), cardiovascular events, and death among patients with advanced chronic kidney disease (CKD) is clinically useful and relevant. We aimed to externally validate a recently developed CKD G4+ risk calculator for these outcomes and to assess its potential clinical impact in guiding vascular access placement. Methods: We included 1517 patients from the European Quality (EQUAL) study, a European multicentre prospective cohort study of nephrology-referred advanced CKD patients aged ≥65 years. Model performance was assessed based on discrimination and calibration. Potential clinical utility for timing of referral for vascular access placement was studied with diagnostic measures and decision curve analysis (DCA). Results: The model showed a good discrimination for KRT and “death after KRT,” with 2-year concordance (C) statistics of 0.74 and 0.76, respectively. Discrimination for cardiovascular events (2-year C-statistic: 0.70) and overall death (2-year C-statistic: 0.61) was poorer. Calibration was fairly accurate. Decision curves illustrated that using the model to guide vascular access referral would generally lead to less unused arteriovenous fistulas (AVFs) than following estimated glomerular filtration rate (eGFR) thresholds. Conclusion: This study shows moderate to good predictive performance of the model in an older cohort of nephrology-referred patients with advanced CKD. Using the model to guide referral for vascular access placement has potential in combating unnecessary vascular surgeries
