Authoritative new text from the experts in GI populationstudies This book covers both key methodological issues and the mostimportant information in the field, disease by disease. It focuseson population-based information and studies looking at principlesand approaches to diagnosis and treatment of diseases. GI Epidemiology brings together world authorities inmultiple disciplines for the very first time, to create one clearand comprehensive source. The bulk of the chapters are divided intotwo parts, covering methodological issues and the epidemiology ofspecific GI diseases. Each chapter begins with a list of keypoints, followed by a review written in a clear and simplestyle. The methodologic chapters cover evidence-based medicine,meta-analysis, systematic reviews, genetic and molecularepidemiology, clinical trials, questionnaire design, and healtheconomics. The disease-specific chapters note the current gaps inknowledge and suggest areas for further study. GI Epidemiology serves as both a useful refresher and areliable reference on the methods and techniques used inepidemiological studies for consultants and researchers ingastroenterology. It is also an invaluable tool for fellows/trainees ingastroenterology, candidates for recertification in the combineddisciplines of gastroenterology, pediatric gastroenterology andcolorectal surgery, and anyone completing MPH training.

Identifying how, why and in whom gastrointestinal disease occurs, and what can be done to prevent it, is of key importance for the modern-day gastroenterologist and researcher. Brought to you by the world’s leading gastroenterologists, the second edition of GI Epidemiology: Diseases and Clinical Methodology is the only book that combines detailed analysis of the epidemiology of GI disease with a study of the methodology of clinical research. With a much greater clinical focus on the diagnostic and management approach for each disease than before, all existing chapters are fully updated with the very latest in statistical and clinical data. In addition, the revised edition contains several significant improvements, notably: • Five extra disease epidemiology chapters: Upper GI Bleeding; Hepatitis B and C; Common Tropical GI Diseases; Nutritional Epidemiology and GI Cancers; and Obesity among Adults • More illustrations, including maps of each disease • A more international focus with the inclusion of two experienced European editors • MCQs, summary checklists and key points throughout • Ten extra online-only chapters on methodological issues related to GI epidemiology such as Patient reported GI Epidemiology: Diseases and Clinical Methodology, 2nd Edition is the perfect reference tool for gastroenterologists involved in both patient management and clinical research, and also for epidemiologists involved specifically in GI disease data and more general epidemiological studies.

Leading experts in the fields of gastroenterology, surgery, and radiology comprehensively review the pathophysiology, diagnosis, management, and treatment of acute bleeding disorders of the GI tract. The authors break down acute bleeding into upper and lower GI tract sources and provide a differential diagnosis for each disease, evidence-based algorithms for clinical practice, treatment modalities for its management, and standards of care. The authors outline the many dilemmas faced by physicians in their approach to their patients, such as localization of the bleeding source (upper vs lower), the need and timing for emergency endoscopy, and the timing for radiologic intervention and/or surgery.

The COVID-19 pandemic has had a significant impact on the epidemiology and etiology of respiratory tract and gastrointestinal infections. The implementation of control measures such as social distancing and hand hygiene was associated with a decrease in the incidence of some respiratory and gastrointestinal infections caused by other viruses and bacteria. Epidemiological data suggest that the incidence of respiratory tract infections other than SARS-CoV-2 infection has decreased during the COVID-19 pandemic, possibly due to the adoption of several non-pharmaceutical interventions in public areas. Currently, there is very little research on the interaction between SARS-CoV-2 and other infectious pathogens in terms of microbiome and virome. As a matter of fact, changes in the epidemiology of respiratory and gastrointestinal infections may be due to other causes than SARS-CoV-2-specific control measures. It is still unclear whether these changes might result from direct interaction between SARS-CoV-2 and the microbiome and/or virome. Continuous and ongoing efforts to understand the impact of the COVID-19 pandemic on infectious diseases are critical in advancing scientific discovery for prevention and treatment strategies for future pandemics. Through this research theme, we aim to explore scientific gaps related to our understanding of the changes in epidemiology and pathogenic agents responsible for respiratory tract and gastrointestinal infections during the COVID-19 pandemic.

As aging trends in the United States and Europe in particular are strongly suggestive of increasingly older society, it would be prudent for health care providers to better prepare for such changes. By including physiology, disease, nutrition, pharmacology, pathology, radiology and other relevant associated topics, Geriatric Gastroenterology fills the void in the literature for a volume devoted specifically to gastrointestinal illness in the elderly. This unique volume includes provision of training for current and future generations of physicians to deal with the health problems of older adults. It will also serve as a comprehensive guide to practicing physicians for ease of reference. Relevant to the geriatric age group, the volume covers epidemiology, physiology of aging, gastrointestinal physiology, pharmacology, radiology, pathology, motility disorders, luminal disorders, hepato-biliary disease, systemic manifestations, neoplastic disorders, gastrointestinal bleeding, cancer and medication related interactions and adverse events, all extremely common in older adults; these are often hard to evaluate and judge, especially considering the complex aging physiology. All have become important components of modern medicine. Special emphasis is be given to nutrition and related disorders. Capsule endoscopy and its utility in the geriatric population is also covered. Presented in simple, easy to read style, the volume includes numerous tables, figures and key points enabling ease of understanding. Chapters on imaging and pathology are profusely illustrated. All chapters are written by specialists and include up to date scientific information. Geriatric Gastroenterology is of great utility to residents in internal medicine, fellows in gastroenterology and geriatric medicine as well as gastroenterologists, geriatricians and practicing physicians including primary care physicians caring for older adults.

Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.
