This book examines the evolution of American universities during the years following World War II. Emphasizing the importance of change at the campus level, the book combines a general consideration of national trends with a close study of eight diverse universities in Massachusetts. The eight are Harvard, M.I.T., Tufts, Brandeis, Boston University, Boston College, Northeastern and the University of Massachusetts. Broad analytic chapters examine major developments like expansion, the rise of graduate education and research, the professionalization of the faculty, and the decline of general education. These chapters also review criticisms of academia that arose in the late 1960s and the fate of various reform proposals during the 1970s. Additional chapters focus on the eight campuses to illustrate the forces that drove different kinds of institutions--research universities, college-centered universities, urban private universities and public universities--in responding to the circumstances of the postwar years.

AbstractThe recent decades have ushered in considerable advancements in the diagnosis and treatment of systemic light chain (AL) amyloidosis. As disease outcomes improve, AL amyloidosis-unrelated factors may impact mortality. In this study, we evaluated survival trends and primary causes of death among 2337 individuals with AL amyloidosis referred to the Boston University Amyloidosis Center. Outcomes were analyzed according to date of diagnosis: 1980-1989 (era 1), 1990-1999 (era 2), 2000-2009 (era 3), and 2010-2019 (era 4). Overall survival increased steadily with median values of 1.4, 2.6, 3.3, and 4.6 years for eras 1–4, respectively (P < 0.001). Six-month mortality decreased over time from 23% to 13%. Wide gaps in survival persisted amid patient subgroups; those with age at diagnosis ≥70 years had marginal improvements over time. Most deaths were attributable to disease-related factors, with cardiac failure (32%) and sudden unexpected death (23%) being the leading causes. AL amyloidosis-unrelated mortality increased across eras (from 3% to 16% of deaths) and with longer-term survival (29% of deaths occurring >10 years after diagnosis). Under changing standards of care, survival improved and early mortality declined over the last 40 years. These findings support a more optimistic outlook for patients with AL amyloidosis.
