Developing a Protocol for Observational Comparative Effectiveness Research: A User's Guide


Book Description

This User’s Guide is a resource for investigators and stakeholders who develop and review observational comparative effectiveness research protocols. It explains how to (1) identify key considerations and best practices for research design; (2) build a protocol based on these standards and best practices; and (3) judge the adequacy and completeness of a protocol. Eleven chapters cover all aspects of research design, including: developing study objectives, defining and refining study questions, addressing the heterogeneity of treatment effect, characterizing exposure, selecting a comparator, defining and measuring outcomes, and identifying optimal data sources. Checklists of guidance and key considerations for protocols are provided at the end of each chapter. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews. More more information, please consult the Agency website: www.effectivehealthcare.ahrq.gov)







Multiple Exposures


Book Description

"Catherine Caufield has written an important book on an important topic: the history behind the safety standards limiting the effects of high energy radiation on human beings. . . . Provides an immense amount of information in a very readable form."—W. Alan Runciman, Prometheus "From fallout and radon to radioactive smoke detectors and dental X-rays, Caufield traces the proliferation of the uses of radiation in medicine, industry and the military, and in generating energy. An intelligent, non-alarmist history."—Publishers Weekly




Anatomic Exposures in Vascular Surgery


Book Description

Revised, updated, and expanded for its Third Edition, Anatomic Exposures in Vascular Surgery, is an indispensable guide for the vascular surgeon planning an operation. This classic anatomic reference contains over 550 drawings by a renowned surgeon and illustrator depicting the complex anatomy of the vasculature and surrounding structures, and demonstrating the ideal exposure techniques. The original illustrations will be presented in full color to fully convey three-dimensional concepts of anatomic relationships of the blood vessels and their surrounding structures, which will help to guide surgical decision-making in vascular surgery. Concise legends and text describe the anatomy in relation to the surgical approach. The book is organized by body region, and chapters are divided into anatomic overview and surgical approach sections, which allows the book to be used for extensive study or quick review, depending on the needs of the reader. New sections to this edition include forearm compartment syndrome, forearm fasciotomy, and vascular exposure of the lumbar spine. New concepts regarding surgical approaches to the blood vessels are updated in each chapter along with up-to-date references.




Holographic Imaging


Book Description

The only all-inclusive treatment of holography—from fundamental principles to the most advanced concepts While several existing texts cover different aspects of the field of holography, none provides a complete, up-to-date, and accessible view of its popular, scientific, and engineering aspects. Now, from an author team that includes one of the world's pioneers in the field, Holographic Imaging fills this need with a single, comprehensive text that covers the subject from traditional holography to the cutting-edge development of the world's most advanced three-dimensional holographic images, holographic printing, and holographic video. Written in an engaging and easy-to-follow style, Holographic Imaging promotes a hands-on approach to making holograms and provides readers with a working understanding of how and why they work. Following a brief introduction to the fundamentals of light and diffraction, coverage includes: the diffraction efficiency of gratings, "platonic" holography, a ray-tracing analysis of holography, holographic lenses and in-line "Gabor" holography, off-axis "Leith & Upatnieks" holography, non-laser illumination of holograms, phase conjunction and real image projection, full-aperture transfer holography, white-light transmission "rainbow" holography, practical issues in rainbow holography, in-line "Denisyuk" reflection holography, off-axis reflection holography, edge-lit holography, computational display holography, holographic printing, and holographic television. Helpful diagrams and equations that summarize the mathematical and physical principles for each technique discussed make this an approachable resource for readers from a variety of backgrounds, including undergraduate and postgraduate students with an interest in optics, optoelectronics, and information display, as well as researchers, scientists, engineers, and technology-savvy artists.
