Description

Vitamin D, a steroid hormone, has mainly been known for its effects on bone and osteoporosis. The current therapeutic practices expand into such markets as cancer research, pediatrics, nephrology, dermatology, immunology, and genetics. This 3e includes over 100 chapters covering everything from chemistry and metabolism to mechanisms of action, diagnosis and management, new analogs, and emerging therapies. This complete reference works is a must-have resource for anyone working in endocrinology, osteology, bone biology, or cancer research.

Readership

Bone specialists, endocrinologists, basic scientists and researchers interested in vitamin D and osteoporosis prevention.

David Feldman

David Feldman, MD, is Emeritus Professor of Medicine (Active) at Stanford University School of Medicine where he has been on the faculty since 1974. He has been a full professor since 1984 and was chief of the Endocrinology Division for 10 years. His laboratory studies the role of steroid hormone receptors, particularly the vitamin D receptor, and its mechanism of action. His current major research focus is hormone-dependent cancer including breast cancer and prostate cancer and the pathways by which vitamin D inhibits cancer growth. Professor Feldman is actively involved in both basic science approaches to the anti-cancer actions of vitamin D as well as to clinical trials studying the use of vitamin D in breast and prostate cancer. Professor Feldman was recently honored with an award for a Career of Outstanding Contributions to Vitamin D Research. He has authored over 290 medical research articles, reviews, editorials, and book chapters. In addition to being a co-editor of all four editions of OSTEOPOROSIS, he is the editor-in-chief of Vitamin D, just published in its third edition.

Quotes and reviews

"In this brief review, it is impossible to cover all the nuances of vitamin D addressed in this book. Interested readers may want to peruse the book chapters to assess relevance to their personal interests. I regard this impressive text as a ‘‘must have’’ in the medical libraries of most hospitals. Clinicians and researchers with an interest in vitamin D may want their own personal copy for ready reference. I highly recommend it and congratulate the authors and editors in providing a much needed reference text on arguably one of the more important nutrients to our species."--American Journal of Human Biology

"In this remarkable compendium, the editors provide a fresh and comprehensive review of a multifaceted and sometimes controversial vitamin D. This third edition is not just an update, but a greatly expanded work organized to authoritatively cover the evidence for new roles of vitamin D in cardiovascular health, immunity, psychiatric disorders, and much more. In more than 100 chapters, experts span the history of vitamin D, update its molecular mechanism and chemistry, provide specifics of clinical use in disorders of the skeleton, and review progress in an array of diseases including diabetes, inflammatory bowel disease, multiple sclerosis, and psoriasis. In this edition one finds new information for a broad audience including internal medicine, nutrition, orthopedics, basic scientists, and teachers. How does one define optimal vitamin D status? How does vitamin D affect innate immunity? What are the epigenetic modifications of the vitamin D receptor that contribute to its function? Are there other natural ligands for the vitamin D receptor? These are a part of the new increased scope of Vitamin D, Third Edition. If you are interested in vitamin D, you should have this book."

—Mark S. Nanes, MD, PhD, Professor of Medicine, Emory University, Atlanta, GA, USA

"The Third Edition of the classic text Vitamin D is a superb summary of an important and topical issue. Its contributors are truly experts in the field and they have managed to comprehensively describe the biochemistry, pharmacology and effects of vitamin D as well as to eloquently weave in the relevant biology of bone, muscle, immunology and other relevant tissues. The 105 readable chapters offer a complete and well balanced mix of basic and clinical topics that provides an opportunity to understand the full breadth of vitamin D action. Each section represents an excellent summary of up-to-date information and, as a whole, this text offers an outstanding resource that will appeal to a broad spectrum of readers – from students to established clinicians and investigators."

—Eric Orwoll, MD, Department of Medicine, Division of Endocrinology, Diabetes, and Clinical Nutrition, Oregon Health and Science University, Portland, OR, USA

"The Third Edition of Vitamin D is well written, comprehensive and balanced. Several of the new chapters, such as Epigenetic Modifications and Wnt/ß-Catenin Signaling, have strayed away from the "traditional" vitamin D but the authors have put these topics very clearly into perspective in ways that will be valuable to those studying vitamin D action. The overall list of authors for this book is a virtual '"who's who" of vitamin D research, and the coverage of the topic is appropriately broad, including those matters in nutrition and epidemiology that have been the subject of much interest in recent years."
