In the last three decades, the prevalence of obesity has doubled with over 600 million obese adults worldwide. The gastrointestinal complications of obesity are well publicized; however, the role of the gastrointestinal tract in the development and treatment of obesity is often understated. From the pathophysiologic role of gut hormones and the microbiota, to the purposeful, anatomic derangement of the gastrointestinal tract that is utilized as a treatment for obesity, it is imperative that gastroenterologists understand the full scope of obesity in relation to the gastrointestinal system. Studies suggest that in the U.S. obesity is underrecognized and undertreated by health care providers. Given its complex sociology, pathophysiology, and treatment, obesity, like many other diseases, requires a multidisciplinary approach. Therefore, gastroenterologists must be equipped with the relevant knowledge of obesity that will empower them to properly manage their patients.

The goal of this issue of Gastroenterology Clinics is to present GI diseases which affect women uniquely, such as pelvic floor problems and pregnancy related disorders, or which require a more considered approach such as functional bowel disease or autoimmune processes. It will also address the position of women and female gastroenterologists in the health system as a whole. This issue is published at an exciting, transitional time in the future of gastroenterology, as we adjust approaches for the assessment of disease in a large portion of our patient population, and as we address the challenges in practicing medicine based on the uniqueness of specific populations.

In this issue of Gastroenterology Clinics, guest editor Dr. Laurie Keefer brings her considerable expertise to the topic of Psychogastroenterology. This burgeoning, multidisciplinary field applies psychological science and practice to gastrointestinal health and illness, providing a patient-centered understanding of GI conditions with roots in the biopsychosocial model of illness. In this unique issue, top experts in psychogastroenterology present reviews on key topics across the spectrum of digestive disorders. - Contains 14 practice-oriented topics including stress, resilience, and the brain-gut axis; the future of brain-gut psychotherapies; psychological considerations in the management of food intolerances; working with trauma in the GI setting; addressing disparities in psychogastroenterology care; and more. - Provides in-depth clinical reviews on psychogastroenterology, offering actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

In this issue of Gastroenterology Clinics, guest editor Dr. John A. Martin brings his considerable expertise to the topic of Advances in Endoscopy. Endoscopy has forever changed the fundamental nature of the clinical gastroenterologist's practice, from one that was originally predominantly clinic-based, to one that, today, is largely driven by endoscopy. In this issue, top experts explore and celebrate the now numerous facets of diagnostic and therapeutic endoscopy that markedly benefit patients today and continually advance to empower the gastrointestinal endoscopist more and more, year by year. - Contains 14 relevant, practice-oriented topics including pediatric endoscopy; ERCP: biliary and pancreatic endoscopy; endoscopic ultrasound; advanced esophageal endoscopy; artificial intelligence in endoscopy; and more. - Provides in-depth clinical reviews on endoscopy, offering actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

Gastrointestinal (GI) cancers account for nearly 150,000 deaths each year, in the United States alone. Encouragingly, environmental risk factors, premalignant conditions, and high-risk familial kindreds are well described for many GI cancers. In this comprehensive volume on GI Neoplasia, all luminal cancers will be discussed, along with pancreas cancer, gastrointestinal stromal tumors (GISTs), carcinoid tumors, and neuroendocrine tumors. Hepatobiliary cancers are not addressed, as these tumors could form the basis of a separate volume. Articles are organized to address several key topics for each cancer type, such as: public health burden, molecular pathways, risk and protective factors, early detection, clinical evaluation, management, and survivorship.

Dr. Quigley has created a must-have reference on the gut microbiome for the practicing gastroenterologist. A leader in the field of human physiology and digestive disorders, he has laid out the basics on this increasingly important topic, devoting articles to the organization and biology of the human gut microbiome as well as its diagnostic potential. Top international authors have presented articles that discuss the intersection of the gut microbiome and diet and the gut-brain axis. Clinical implications of the gut microbiome are discussed with disease states like IBD, GI cancer, and liver diseases. Finally, the issue ends with the cutting-edge clinical innovation of fecal microbial transplantation. This issue bridges the gap between science and clinical practice and should be an important reference to practicing gastroenterologists.
