BACKGROUND AND PURPOSE Adherence to medication is often suboptimal after stroke and transient ischemic attack (TIA), which increases the risk of recurrent stroke and death. Complex interventions and motivational interviewing (MI) have been proven effective in other areas of medicine. The objective of this study was to investigate the effectiveness of a(More)
PURPOSE We present a systematic screening for identifying associations between prescribed drugs and cancer risk using the high quality Danish nationwide health registries. METHODS We identified all patients (cases) with incident cancer in Denmark during 2000-2012 (n=278,485) and matched each case to 10 controls. Complete prescription histories since 1995(More)

Treatment of autoimmune myasthenia frequently involves long-term exposure to immunosuppressants, including azathioprine. Use of azathioprine increases the risk of NMSC in organ(More)
