How can the virus be suppressed while reducing the progression of liver disease?

Host: Mark DeLegge, MD Guest: William J. Sandborn, MD The current treatment paradigm for Crohn's disease is a pyramid approach, where patients are given the safest medications before pursuing more aggressive strategies. New evidence suggests that Crohn's disease should be treated with the most effective medications first, such as anti-TNF therapies. But is a top-down strategy safe enough for most patients? Dr. William Sandborn, professor of medicine and gastrointestinal research at Mayo Clinic College of Medicine, describes the results of new Crohn's disease trials and research. Is using steroids to treat Crohn's disease an idea of the past, or are steroids still effective for certain patients? Dr. Mark DeLegge hosts.

Guest: Prateek Sharma, MD Host: Mark DeLegge, MD Esophageal cancer survival rates greatly decline when the cancer has reached its late stages, so detecting neoplasia in a Barrett's esophagus patient early is a crucial tool in cancer management. What are some emerging endoscopic techniques that can be used for a Barrett's esophageal patient? Dr. Prateek Sharma, professor of medicine in the division of gastroenterology and hepatology at the University of Kansas School of Medicine, discusses the best ways to manage esophageal cancer and Barrett's esophagus patients with host Dr. Mark DeLegge.

Guest: Brennan Spiegel, MD, MSHS Host: Jay Goldstein, MD In its 1948 charter constitution, the World Health Organization defined health as "a state of complete physical, mental and social well-being." Today, to measure this totality of well-being, we measure quality of life. Host Dr. Jay Goldstein discusses how quality of life measurements can be incorporated into everyday practice, with Dr. Brennan Spiegel, assistant professor of medicine in the division of digestive diseases at the David Geffen School of Medicine at UCLA. How is health-related quality of life measured objectively in clinical trials? To what degree do quality of life endpoints trump physiological endpoints?
