American Journal of Gastroenterology Author Podcasts

Robin C. Spiller, MD, FRCP, co-author of new research on the effect of FODMAPs such as fructose and fructans on irritable bowel syndrome (IBS) symptoms published in January 2014 issue of AJG, talks with AJG co-Editor Dr. William D. Chey about the dietary substances included in the FODMAP classification, the MRI imaging techniques used to measure FODMAP impact on colonic distention and gas production in this study, and how clinicians might consider FODMAPs along with gluten and lactose when recommending dietary interventions for IBS patients.

David A. Johnson, MD, FACG, co-author of new research on the emerging impact of online patient evaluation websites (PEWs) published in the Red Section of the November issue of AJG, talks with AJG co-Editor William D. Chey, MD, FACG, about the rating metrics used by these websites, the characteristics of typical users, and the potential ways in which physicians can interact with these sites to improve doctor-patient communication and manage their online reputation.

Scott Tenner, MD, MPH, FACG, co-author of the American College of Gastroenterology's new Clinical Guideline on the Management of Acute Pancreatitis, published in the September issue of AJG, talks with co-Editor Dr. William Chey about the increasing prevalence of acute pancreatitis; the appropriateness of CT, MR, ERCP, and genetic testing in diagnosis of the disease; and the role of antibiotics, re-feeding, surgical debridement, and lactated ringer's solution versus normal saline in the management of acute pancreatitis.

Michael F. Vaezi, MD, FACG, John E. Pandolfino, MD, and Marcelo F. Vela, MD, co-authors of the American College of Gastroenterology's new Clinical Guideline on the Diagnosis and Management of Achalasia published in the August issue of AJG, talk with co-Editor Dr. Paul Moayyedi about the incidence, prevalence, and diagnosis of this disorder; the best treatment options-including myotomy, pneumatic dilatation, and botulinum toxin-according to achalasia subtype and patient age, gender, and preference; as well as the long-term outlook and risks for achalasia patients after successful therapy.

Michael F. Vaezi, MD, FACG, and David O. Francis, MD, co-authors of new research on the high costs of caring for patients with extraesophageal reflux symptoms published in the June issue of AJG, talk with AJG co-Editor Dr. Paul Moayyedi about the prevalence of various extraesophageal reflux symptoms, the costs of treating these symptoms, the impact of tertiary care centers in both patient improvement and health care costs, and whether the best treatment for extraesophageal reflux is perhaps no treatment at all.

David A. Katzka, MD, FACG, co-author of the American College of Gastroenterology's new Clinical Guideline on the Diagnosis and Management of Esophageal Eosinophilia and Eosinophilic Esophagitis (EoE), talks with AJG Co-editor Dr. Paul Moayyedi about the key components of the guidelines, including the epidemiology of the disease, the difficulty of diagnosis for EoE, the role of diet and pharmacological therapy for treatment of EoE, and the urgent need for more research into this disease.

Philip O. Katz, MD, FACG and Lauren B. Gerson, MD, MSc, FACG, two authors of the American College of Gastroenterology’s new Practice Guidelines for the Diagnosis and Management of Gastroesophageal Reflux Disease (GERD), talk with AJG Co-editor Paul Moayyedi, MD, FACG, about the key components of the guidelines, including the prevalence of GERD, the recommendations for the approach to diagnosis and management, and the potential adverse events associated with PPI therapy.

The American Journal of Gastroenterology (AJG) Co-Editor Paul Moayyedi, MD, FACG, talks with Henry P. Parkman, MD, FACG, of Temple University, one of the lead authors of a new clinical guideline for the management of gastroparesis. Published in the January issue of AJG, the guideline addresses the definition, diagnosis, differential diagnosis, and treatment of gastroparesis, including nutritional supplementation, glycemic control, pharmacological, endoscopic, device, and surgical therapy. Dr. Parkman provides insight on the guideline’s key recommendations, including the scientifically-based evidence behind them.

AJG Journal co-editor Dr. Paul Moayyedi talks with William D. Chey, MD, FACG and Satish Rao, MD, PhD, FACG about to two randomized controlled trials on linaclotide in irritable bowel syndrome (IBS) published in the December issue of The American Journal of Gastroenterology. The phase 3 trials report that this new therapy significantly reduces constipation and abdominal pain associated with some kinds of IBS.

Findings from a new meta-analysis focusing on non-referral studies suggest that 5-Aminosalicylic Acid offers little, if any, protection against colorectal cancer in Inflammatory Bowel Disease. In a conversation with AJG Co-Editor Dr. Paul Moayyedi, co-investigators Geoffrey C. Nguyen, MD, PhD, FRCPC and Charles N. Bernstein, MD explain why their findings conflict with previous clinic-based population studies and why 5-ASA should not be prescribed to IBD patients solely for their putative effects against CRC.

Findings from a new meta-analysis portray a cautionary tale on the use of PPI therapy in patients at significant risk of C. difficile infection. In conversation with AJG Co-Editor, Dr. William D. Chey, MD, Dr. Yoon K. Loke discusses his latest research findings that suggest concurrent use of antibiotics with PPIs increases the risk of CDI; and a lower risk of CDI with use of H2RAs.

Professor Peter Gibson reviews the quality of the evidence on diets high or low in poorly absorbed short-chain carbohydrates, known as FODMAPs (Fermentable Oligo-, Di- and Mono-saccharides and Polyols) and their impact on functional gastrointestinal symptoms. In a discussion with Co-Editor Dr. Bill Chey, Professor Gibson provides insights on implementing dietary approaches in the office and discusses the challenges of recognizing patients with non-celiac gluten sensitivity.

A conversation with Loren A. Laine, MD, FACG hosted by Dr. Chey on ACG's new practice guideline, "Management of Patients with Ulcer Bleeding."
