  3. GI infections.
  4. Liver, gallbladder and biliary system.
  5. Mouth/oropharynx and GI cancers.
  6. Digestion/absorption and vitamins.
  7. Nutrition.
  8. Metabolism and introduction to diabetes.
  9. Diabetes treatments.
  10. Obesity.

Learning Objectives

Educational Program Objectives are a subset of more broadly defined physician competencies, which represent general domains of performance for which the profession and the public hold physicians accountable.

Upon completing the GIMDO Block, students should be able to:

  • Describe key events in the development of the GI, hepatic, biliary and pancreatic systems and malformations that can occur.
  • Recognize key organs and structures in images from various modalities including selected abnormalities and disease states.
  • Describe the functions of these key organs and/or structures with respect to:
  • Digestion/absorption;
  • Endocrine and/or exocrine functions including digestion;
  • Homeostasis of nutrients, electrolytes, fluid, etc.;
  • The role of the liver in drug metabolism and detoxification of exogenous compounds;
  • Features of the microbiome at various sites as presented in lecture;
  • Relationship to other systems, e.g., circulatory, lymphatic;
  • Control by the nervous system.
  • Outline key biochemical pathways and describe the consequences of genetic mutations in key metabolic enzymes. Recognize which of these defects are tested in newborns in Arizona. Outline the key role of vitamins in metabolic and antioxidant pathways and describe the effects of vitamin deficiencies (or toxicity).
  • List key GI, liver and metabolic disorders and describe their etiology (genetics, lifestyle, etc.), incidence and risk factors (including gender or ethnic discrepancies) and behavioral or societal components, including the following: Lactose intolerance, gastric ulcers, gastroesophageal reflux, hernias, type 1 and type 2 diabetes mellitus, hyperlipidemias, familial hypercholesterolemia, Crohn’s disease, ulcerative colitis, celiac disease, intestinal diverticula, cholecystitis, pancreatitis, cholelithiasis, gastritis (various causes), appendicitis, GI and oral cancers, GI infections, hepatitis, hepatic failure, ascites, malabsorption disorders, hepatocellular cancer, eating disorders and others as deemed appropriate by the faculty.
  • Describe the differential diagnostic process for distinguishing the disorders listed in BLO5 [lactose intolerance, gastric ulcers, gastroesophageal reflux, hernias, type 1 and type 2 diabetes mellitus, hyperlipidemias, familial hypercholesterolemia, Crohn’s disease, ulcerative colitis, celiac disease, intestinal diverticula, cholecystitis, pancreatitis, cholelithiasis, gastritis (various causes), appendicitis, GI and oral cancers, GI infections, hepatitis, hepatic failure, ascites, malabsorption disorders, hepatocellular cancer, eating disorders and others as deemed appropriate by the faculty] and as presented in lecture or CBI and recognize key new advances in diagnostics, such as genomic testing, that provide novel opportunities not only for diagnosis, but also for screening and prevention.
  • Explain the rationale for prevention and therapy for the disorders listed in BLO5  [lactose intolerance, gastric ulcers, gastroesophageal reflux, hernias, type 1 and type 2 diabetes mellitus, hyperlipidemias, familial hypercholesterolemia, Crohn’s disease, ulcerative colitis, celiac disease, intestinal diverticula, cholecystitis, pancreatitis, cholelithiasis, gastritis (various causes), appendicitis, GI and oral cancers, GI infections, hepatitis, hepatic failure, ascites, malabsorption disorders, hepatocellular cancer, eating disorders and others as deemed appropriate by the faculty], including lifestyle and nutrition, and how communication with the patient can facilitate compliance with such therapies.
  • List appropriate drugs and describe in general terms their mode of action (if known) and major side effects or risks (if any): Antibiotics, antivirals, anti-inflammatories, anti-reflux, anti-tumor, weight-loss drugs, anti-diabetics and others as deemed necessary by the faculty in view of above disorders.
  • Recognize the GI/metabolic side effects of drugs commonly used for other disorders, such as: NSAIDs, bone antiresorptive drugs, antihypertensives, etc.
  • Recognize the contributions of diet, genetics and lifestyle to the development of disorders as listed in BLO5, and how communication with the patient can facilitate compliance with such therapies. Explain the role of diet, lifestyle and genetics in the development of obesity and its potential progression to type 2 diabetes, but also the potential for changes in diet and exercise to promote a healthy lifestyle at all stages of the human life cycle.
  • Describe ways in which physicians can practice cultural competency in treating patients from various ethnic or religious backgrounds.
  • Recognize the part played by federal agencies in providing and/or regulating health care and briefly describe the role(s) of each agency as presented in lecture.
  • Discuss how to best prioritize diagnostic procedures and identify potential negative impacts on patients when piecemeal work-up is pursued. Describe how a cost-effective work-up supports the concepts of value-based care.
