The Evolution of Retirement as Systematic Ageism

Questions that people ask, when they hear that mandatory retirement has been repealing include: will people be forced to toil longer to stay financially healthy? Will they change careers later in life to keep their interest in a subject or explore new interests? How will working longer affect their health? How will much older people affect the ambitions and working styles of younger colleagues? Will companies have to change their health and benefit plans to accommodate older people? This chapter discusses implications for both individuals and companies about hiring/retaining workers beyond the mandatory retirement age including differences in power relationships that place older workers who love and want to stay in their job in a compromised position. Issues related to international political economy will be addressed

SPECT myocardial perfusion imaging for the assessment of left ventricular mechanical dyssynchrony

Phase analysis of gated single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is an evolving technique for measuring LV mechanical dyssynchrony. Since its inception in 2005, it has undergone considerable technical development and clinical evaluation. This article reviews the background, the technical and clinical characteristics, and evolving clinical applications of phase analysis of gated SPECT MPI in patients requiring cardiac resynchronization therapy or implantable cardioverter defibrillator therapy and in assessing LV diastolic dyssynchrony
