Despite the fact that the incidence of gastric cancer is declining in the Western world, it remains a significant problem with respect to accurate diagnosis and treatment since it has a high mortality rate. In June 1989 an International Conference was held at the University of Rome "La Sapienza" entitled "New Trends in Gastric Cancer: Background and videosurgery." During this meeting background information on the aetiopathogenesis of gastric cancer was presented together with talks and video presentations on the latest advances in the treatment of gastric carcinoma, both from the European and Japanese experience. Because of the poor prognosis of gastric carcinoma there is increasing pressure for early detection. Some of the problems in the early detection of gastric carcinoma are discussed together with methods of surveillance of high-risk subjects. It is generally accepted that the surgical approach to gastric carcinoma should take into account the site and extent of the lesion and there are chapters on new methods for pre and intraoperative staging of the disease which allow a more logical approach to surgery. A comparison between Japanese and Western rule and results was attempted and reasons for the differences were investigated. Since the field is still evolving not all aspects could be covered, and those angles not approached in this book will be addressed in a second International Conference to be held in Rome in June 1990.

Medical nutrition therapy plays a central role in the management of diseases including reducing disease risk, slowing disease progression, and monitoring nutritional status. Though a nutrition care process has been implemented in some countries, many do not have a national standard for nutrition and dietetic practices for different diseases including the scope of gastrointestinal disorders. Moreover, there is no guidance to dietetic practice by most of the governing bodies of the world. Cases on Medical Nutrition Therapy for Gastrointestinal Disorders presents real-world case studies on nutrition assessment, diagnosis, intervention, monitoring, and evaluation standards and practices. Moreover, the cases provide critical updates on the use of medical nutrition therapy for gastrointestinal disorders that include but are not limited to Celiac Disease, Crohn's Disease, Irritable Bowel Syndrome, constipation, and bowel obstructions and discusses strategies for the prevention and management of these disorders. Registered dietitians, dietetic interns, nutritionists, healthcare professionals, researchers, academicians, and students will benefit from the scenarios presented within this book.

The obesity epidemic has generated immense interest in recent years due to the wide-ranging and significant adverse health and economic consequences that surround the problem. Much attention has been focused on behaviors that lead to obesity, in particular to over consumption of energy-dense food and to sedentary lifestyle. However, obesity is an extremely complex condition with poorly defined pathogenesis. Thanks to greatly enhanced research in the area, the discovery of pathways in the brain and peripheral organs that mediate energy homeostasis has provided a framework for understanding the biological basis of obesity. Metabolic Basis of Obesity adds an important new dimension to the growing literature on obesity by offering a comprehensive review of specifically how metabolic imbalance culminates in obesity. Developed by a team of expert authors, this important title discusses the principles of energy balance, genetics of body weight regulation, hormones and adipokines, and metabolic pathways in the brain, liver, muscle and fat, to name just several of the areas covered. The book also examines the connection between obesity and diabetes, cardiovascular disease and other complications. Current and future diagnostic and treatment strategies are also reviewed. Comprehensive and timely, Metabolic Basis of Obesity is an essential reference for understanding the burgeoning problem of obesity.

By 1977 it was clear that the thermophilic campylobacters were a major cause of acute bacterial enteritis. In response to that observation an international workshop was convened in Reading, England, and attracted over 130 participants. Many of these individuals resolutely returned for the eighth in the series of biennial international workshops, this time held in Win chester, England, in July 1995. All were surprised at the continued, and even expanding, re search effort in this narrow microbiological field. Such a lasting interest is undoubtedly a reflection of a consistent rise in the incidence of infection, the growing number of closely re lated organisms and disease associations, and an ever-increasing awareness by the public and government agencies of public health and food safety issues. The second workshop in Brussels in 1983 was a forum that demonstrated the growing awareness in the campylobacter community of the existence of campylobacter-like organisms and provided the platform for presentations describing the association of these organisms, now classified in the genus Helicobacter. with gastroduodenal disease. The clinical aspects of the research into helicobacters is now thoroughly covered in several other meetings, and the remit of the international workshop has been expanded to provide a forum for the presentation of the basic microbiological research carried out on these bacteria. In a continuation of this ap proach the remit of the workshop has been further extended to other related organisms, reflect ing that there are many other campylobacter-like organisms still to identify and characterize."

An important milestone in medicine has been the recent completion of the Human Genome Project. The identification of 30,000 genes and their regulatory proteins provides the framework for understanding the metabolic basis of disease. This advance has also laid the foundation for a broad range of genomic tools that have opened the way for targeted genetic testing in a number of medical disorders. This book is designed to be the first major text to discuss genomics-based advances in disease susceptibility, diagnosis, prognostication, and prediction of treatment outcomes in various areas of medicine. After building a strong underpinning in the basic concepts of genomics, the authors of this book, all leaders in the field, proceed to discuss a wide range of clinical areas and the applications now afforded by genomic analysis.

R. Fuller 1.1 DEVELOPMENT OF COMMERCIAL PREPARATIONS The history of the probiotic effect has been well documented many times previously (see e.g. Bibel, 1982; Fuller, 1992). The consumption of fermented milks dates from pre-biblical times but the probiotic concept was born at the end of the last century with the work of Metchnikoff at the Pasteur Institute in Paris. In the century that has elapsed since Metchnikoff's work, the probiotic concept has been accepted by scientists and consumers throughout the world. Attempts to refine the practice from the use of traditional soured milks to preparations containing specific micro organisms have occupied the thoughts and endeavours of scientists in many different countries. But, in spite of the large amount of effort expended in attempting to explain and define the effect, it has to be admitted that little is known of the way in which probiotics operate. There are likely to be several different mechanisms because it seems highly improbable that a mode of action that explains resistance to microbial infection will also hold true for improved milk production or alleviation of lactose malabsorption."

In the past 15 years much evidence has accumulated which indicates the paramount importance of sensory nerves in reg ulating functions of the gastrointestinal tract. In parallel, the attention of researchers in this field has been increas ingly attracted to the role played by neuropeptides in the normal and diseased gut. Basic research on the peculiar properties of capsaicin, the pungent ingredient from plants of the genus Capsicum, has allowed the gap between these two areas of research to be bridged. Sincethen, the study of gut afferents and neuropeptides has become more and more interconnected and recognized as a major avenue to understand ing the pathophysiology of various human diseases. It is widely recognized that a certain subset of primary afferents synthesize, store and release neuropeptides (such as tachykin nins and calcitonin gene-related peptide) from their central and peripheral endings, the latter being widely distributed in the alimentary canal and related organs (liver, pancreas). The First International Meeting on Sensory Nerves and Neuropeptides in Gastroenterology, held in Florence from December 4-5, 1989, sponsored and organized by Fondazione Internazionale Menarini, aimed to focus the current status of research in this field. The contributions presented at the meeting and in this book delineate a suggestive scenario in which sensory nerves of the gut, and the multiple messages they carry through the release of neuropeptides, are to be considered as a major target for the development of new drugs potentially useful in a number of diseases of the gastro intestinal tract."

Nearly 30 years ago, a number of scientists working on the Enteric Nervous System (ENS) gathered at Flinders University, in Adelaide, Australia to discuss the advances and future of their research. It was a friendly and stimulating meeting, attended by most of the major players, in what was to become the discipline of 'Neurogastroenterology'. In 2014, the main Australasian Neuroscience Society meeting was held in Adelaide, Australia, providing the perfect opportunity to recreate a follow-up ENS meeting. As such, the 'ENS II 2014 meeting' aimed to identify how far the field of enteric neuroscience had developed, where the future was heading, and what technological advances had been made to address current and future unresolved questions. 30 speakers from around the world were invited to give talks and revisit the original expectations, the advances made since, and the future directions of ENS research. These discussions included three generations of investigators from 7 different countries. This publication represents the majority of proceedings from the 'The Enteric Nervous System II 2014' conference, which was held on February 1st - 2nd 2014 at the National Wine Centre of Australia, Adelaide. This meeting was an Official satellite meeting of the 34th Annual Meeting of Australasian Neuroscience Society, which was also held in Adelaide. The 20 contributions contained within this submission are from international researchers in the field of the ENS, who reviewed the advances made since the first meeting in the early 1980s and summarizes the present and future perspectives of neuro-gastroenterology. Some colleagues could not attend but did send greetings and their messages are included in these proceedings.

The majority of the obese population still does not take advantage of the available surgical possibilities. Clinical research should be oriented towards less invasive procedures that could be accepted by the mainstream.

This book opens with an introduction to the main purpose and tasks of the GIANA challenge, as well as a summary and an analysis of the results and performance obtained by the 20 participating teams. The early and accurate diagnosis of gastrointestinal diseases is critical for increasing the chances of patient survival, and efficient screening is vital for locating precursor lesions. Video colonoscopy and wireless capsule endoscopy (WCE) are the gold-standard tools for colon and intestinal tract screening, respectively. Yet these tools still present some drawbacks, such as lesion miss rate, lack of in vivo diagnosis capabilities, and perforation risk. To mitigate these, computer-aided detection/diagnosis systems can play a key role in assisting clinicians in the different stages of the exploration. This book presents the latest, state-of-the-art approaches in this field, and also tackles the clinical considerations required to efficiently deploy these systems in the exploration room. The coverage draws upon results from the Gastrointestinal Image Analysis (GIANA) Challenge, part of the EndoVis satellite events of the conferences MICCAI 2017 and 2018. Each method proposed to address the different subtasks of the challenges is detailed in a separate chapter, offering a deep insight into this topic of interest for public health. This book appeals to researchers, practitioners, and lecturers spanning both the computer vision and gastroenterology communities.

Inflammation in gastrointestinal mucosa can remodel the topography of the overlying epithelium. If such inflammation is chronic, it has fundamental clinical consequences, the principal of which is premalignant metaplasia throughout the alimentary tract. Furthermore, mucosal inflammation, even if subtle, is the single most common pathway for GI cancer. This book discusses all aspects of the relation between inflammation and GI cancer, from the basic science through to the translational science which is helping in the optimization of clinical management strategies. Among the topics considered are the impact of inherited syndromes; the roles of acid reflux, H. pylori, inflammatory bowel disease, and primary sclerosing cholangitis; screening strategies; targeted drug therapies; genetics; and the use of endoscopic methods. The authors are the best in their field, and this book is designed for the enthusiastic student as well as the professional in GI science and medicine.
