Very interesting. Thanks for sharing. I am still not sold on the whole artificial pancreas thing - I think it offers some promise for improved treatment definitely, but I don't think it's going to be the "cure" so many people hope for.
My biggest concern about this study is that the range of what was considered a "normal" BG was 70-180 mg/dL. If you stay in the 170s for several hours, that's not good. I also have concerns about the accuracy of the CGMs. They are still not terribly accurate and I would be worried that my CGM would signal that I'm low and shut off my pump when I'm really in range, and then I'd end up really high (if not in DKA).
I guess I question some of these efforts when there are still so many other issues, like inaccurate home meters and T1s who aren't able to afford the current standard of care (pumps, for example). Are we just creating another mode of treatment that will be out of reach for even more people?
