Dr. Patterson's absence is easy to explain: he's a scientist, not a PR guy and not a CYDY business plan guy. It's always nice to hear from him, sure, but at this point he has nothing to say. Status of the paper? "In review." Status of the trials? "In progress." He won't give details on the paper until it is accepted and won't give any more info on the trials until the data are unblinded. There's no need for him to give tutorials at this point...the trial enrollment is wrapping up in a matter of days, and there's no point in him making an appearance when there will be so much to talk about in the coming weeks. I'd rather have him in the lab working on research than making a bunch of press appearances.
