αKlotho and fibroblast growth factor-23 (FGF23) were discovered independently about 20 years ago. Since their initial description, a series of exciting discoveries have revealed the important role of endocrine and paracrine FGF23 and αKlotho signaling not only for the physiological regulation of mineral and bone homeostasis, but also for the pathophysiology of diseases such as chronic kidney disease, left ventricular hypertrophy, myocardial infarction, hypertension, and disorders characterized by impaired bone mineralization. The 11 articles compiled in this Research Topic consist of three Original Research articles and 8 Reviews or Mini Reviews, and are an excellent source of information about the state of the art in the FGF23/αKlotho field, covering almost all aspects of FGF23/αKlotho biology.

Fibroblast growth factors (FGFs) have been recognized primarily as autocrine/paracrine factors that regulate embryonic development and organogenesis. However, recent studies have revealed that some FGFs function as endocrine factors and regulate various metabolic processes in adulthood. Such FGFs, collectively called endocrine FGFs, are comprised of three members (FGF15/19, FGF21, and FGF23: FGF15 is the mouse ortholog of human FGF19). These endocrine FGFs share a common structural feature that enables the endocrine mode of action at the expense of the affinity to FGF receptors. To restore the affinity to FGF receptors in their target organs, the endocrine FGFs have designated the Klotho family of transmembrane proteins as obligate co-receptors. By expressing Klothos in a tissue-specific manner, this unique co-receptor system also enables the endocrine FGFs to specify their target organs among many tissues that express FGF receptors.

We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year.

Nutrition in the Prevention and Treatment of Abdominal Obesity focuses on the important roles that exercise, dietary changes, and foods play in promoting as well as reducing visceral fat. Nutritionists, dieticians, and healthcare providers seeking to address the abdominal obesity epidemic will use this comprehensive resource as a tool in their long-term goal of preventing chronic diseases, especially heart, vascular, and diabetic diseases. Experts from a broad range of disciplines are involved in dealing with the consequences of excessive abdominal fat: cardiology, diabetes research, studies of lipids, endocrinology and metabolism, nutrition, obesity, and exercise physiology. They have contributed chapters that define a range of dietary approaches to reducing risk and associated chronic diseases. They begin by defining visceral obesity and its major outcomes; they also discuss the importance and the challenges of dietary approaches to reduce abdominal obesity, as compared to clinical approaches, with major costs and risks. - Offers detailed, well-documented reviews outlining the various dietary approaches to visceral obesity with their benefits and failures - Includes chapters on types of foods, exercise, and supplements in reducing obesity and its chronic clinical companions, especially diabetes and cardiovascular disease - Helps nutritionists, dieticians, and healthcare providers approach patients in making decision about nutritional therapies and clinical treatments for abdominal obesity, from an evidence-based perspective

Hypoparathyroidism, a condition in which insufficient parathyroid hormone (PTH) is produced to maintain normocalcemia is associated with a variety of acute and chronic symptoms and complications due to hypocalcemia. Replacement therapy utilizing PTH has long been awaited, and this book is new and very timely as it coincides with the publication of results on the role of the PTH molecule in the pharmacological management of this disorder. This advance is sparking renewed interest in hypoparathyroidism, which is attributable to neck surgery in most cases and to inherited disorders in a minority. Hypoparathyroidism has been written by acknowledged experts in the field and provides essential, up-to-date information on the pathology, diagnosis, and treatment of the condition. It opens by addressing in detail the anatomy and physiology of the parathyroids and describing the epidemiology and clinical presentation of hypoparathyroidism. The full range of hypoparathyroid disorders are then discussed, including the various genetic forms, postoperative hypoparathyroidism, and other forms of acquired hypoparathyroidism. Individual chapters focus on refractory disease, the impact of the condition on bone, and the management of acute hypocalcemia. Both conventional treatment for hypoparathyroidism and the novel replacement therapy with PTH peptides are then thoroughly examined. Pseudohypoparathyroidism is also extensively discussed, with information on the various forms, differential diagnosis, and genetic testing. This book will be of interest to all endocrinologists, and also to surgeons and internal medicine physicians.

Phosphorus is an essential nutrient that occurs in almost all foods and is important for many normal physiological functions. In a typical Western diet, it is not harmful, but does adversely affect tissues in the body when consumed in excess or deficiency. This book provides a comprehensive review of various aspects of phosphorus in relation to human nutritional needs. Sections cover phosphorus nutrition and dietary issues; health risks associated with excess phosphorus intake that exceeds requirements; phosphorus intake in populations at risk; regulatory challenges and policy approaches; and environmental impacts of phosphates in the modern food supply. This book challenges the long held ideas that high dietary phosphorus intake beyond nutritional requirements is safe and the natural supply of phosphorus critical to agricultural and human food production is endless. Controversy surrounds the claim that largely unrestricted use of phosphorus in all aspects of food production from farm to fork increases dietary phosphorus intake and irretrievable environmental loss, both of which harm human and environmental health. The book editors have joined together experts in basic, medical, environmental, nutritional, and food science to explore the validity of these claims of harm from high intakes and the unchecked use of phosphorus in the global food supply. Despite the essential need for adequate phosphorus over all stages of plant, animal and human life, the growing evidence points to a worldwide increase in dietary phosphorus intake far beyond nutrient requirements, significant association with chronic disease risk even when renal function is not compromised, and the increase in environmental loss with crop run-off, animal husbandry, and unretrieved phosphorus from human waste. This current evidence alludes to a depleted, unsustainable natural supply of phosphorus, hazardous environmental pollution of lakes and waterways, and significant increases in the risk of kidney, skeletal, and other serious illnesses in humans in the future if action is not taken now.
