Environmental chemical hazards are a highly contentious topic in modern life. Nearly every nation on earth has faced its own environmental crises, and also shares perspectives on the possibility of global catastrophes. Of the many global concerns we face, the environmental issue is unique in many ways. The greatest of these is the fundamental scientific nature of the issue, and the extent to which our opinions are formed based on high-level scientific inquiry and assessment. The two key fields of study on this issue, environmental epidemiology and exposure assessment, are still given separate names because of their separate historical roots and scientific traditions, but are seen increasingly as inseparable aspects of the same basic investigation. In this book, Thomas J. Smith and David Kriebel assert that important advances in the quantification of environmental risks can only come through a true synthesis of the two fields. They have built a common biologic model of exposure, physiologic response, and disease, a synthesis of the various existing models which serves to both simplify and improve the application of environmental epidemiology and exposure assessment to current and future environmental chemical risks.When exposure assessor and epidemiologist agree from the start on the model for their study, the conceptual framework for the study they design and the analyses they carry out are much more likely to yield useful exposure-risk information. An explicit biologic model of the apparent processes linking exposure to disease should form the basis for any study seeking to quantify risk from environmental chemicals.

National expenditures for medical care in the months and days preceding death are enormous. But we do not know whether that money is buying good quality care or optimizing the quality of life of those dying, or whether the situation is getting better or worse over time. The information that exists a /describing deatha at a national level a " though some of it is very informative a " is fragmentary. This report recommends ways to fill the information gaps by better use of existing nationally-representative data, and through some new measures, in particular, a new, ongoing National Mortality Followback Survey. The aim is to allow us to benchmark where we are today as a society, and what goals we can set to minimize pain and suffering and maximize the quality of life of all of us who will die in the years to come.

In this issue of Interventional Cardiology Clinics, guest editor Dr. Thomas Smith brings his considerable expertise to the topic of Multi-Modality Interventional Imaging. Top experts in the field discuss key topics such as tricuspid valve TEER guidance with transesophageal echocardiography and ICE; 4D ICE: the next frontier in structural imaging guidance; multiplanar reconstruction: advanced 3D TEE techniques to guide complex structural procedures; CT procedure planning for transcatheter mitral valve replacement; use of CT for LAAO procedure planning and post-procedure assessment; and more.

Understanding the conditions under which variability in performance may arise, and the processes related to its emergence, gives us insight into the development of techniques for improving the quality of performance.This book introduces a comprehensive framework for understanding human performance variability in terms of how human control of behavior is closely tied to design factors in the performance environment. Empirical evidence, as well as practical examples and application areas, introduced in support of this framework. The book provides suggestions on how individuals, groups, and organizations can significantly reduce variability in human performance that often leads to systems failures.
