Not that I recall. Some discussed how concerning it is we really don't know--how is one then going to treat the disease if we don't understand it? I believe they said the usual factors leading to IBD are Environment, Antibiotics, Genetics, and maybe others (diet?). One of the speakers is looking into the role of probiotics, which specific ones for specific individuals and what triggers could be involved.
My own thoughts, if you don't mind, are to look at the specific differences developed countries have with those less developed, in general: antibiotic use (even once), diet, and outdoor activity. Antibiotics could destroy the very guys that helped bring balance to our system. Though our lives may be saved because of antibiotics, there have been studies that show autoimmune conditions result from them (one comes to mind: mice developed allergies after exposure to antibiotics and allergens, whereas those that did not receive antibiotics did not develop this condition). Having an improper diet also affects the proliferation of which microbes in our gut survive and our overall health in general. I could go on as to why I believe this to be the most promising to research, but I'll refrain for now. (Maybe there is something to that "fecal matter transplant" idea--so many microbes that we are unaware of their role.) Not getting enough excercise and getting enough Sun may also be a factor for some, because our ancestors likely got much more than us, and there is some link with lack of vitamin D and certain diseases. I don't think there is hard data for this and I'd be inclined to think of it as a secondary factor.
