I’ve been looking to try an CGM to see how all those factors affect my blood sugar. Is Dexcom Stelo the best available OTC? How do you like the analytics in the app?

I didn't look at the competition. I knew the Dexcom brand because my friends have had good experiences with the G series, so the Stelo was an easy impulse purchase. I'm neither diabetic nor prediabetic, so I'm not a good representative of those audiences. For someone glucose-curious like me, the Stelo is just right. The app provides a slightly laggy real-time graph of measurements (collected every 5 minutes and repor…

Thank you! You just convinced me to get one.

How does that indicate that they didn't address the accuracy of their technology, as the GGP claims? > The existing alternatives do have access to the bloodstream. So? Who says otherwise? People don't want invasive tests that have direct contact with their bloodstream.

If you're type 1 diabetic, accuracy is paramount, especially in a closed loop insulin pump setup. Even with access to the bloodstream, existing CGMs leave plenty of room for improvement that would directly improve quality of life a lot more than the annoyance of applying the sensor under the skin.

Not having to pay $50-100/mo for CGM patches would also be nice.

Oh there will be a subscription, don’t worry about that.

It's a university research, not in-company. The tech is published.

Who says that's not addressed by this technology?

> directly improve quality of life a lot more than the annoyance of applying the sensor under the skin

How annoying is it? They don't cut a hole and insert it. How can you say how much it would improve the quality of life?

I don't see where all these assumptions about this technology come from.

I have probably seen "viable" overinterpreted 100s of times by now. Perhaps we need to re-interpret the 'V' in "MVP" as "VC-investable" or perhaps replace it with 'I' to be I)nvestible which gets you a more pronounceable "MIP" (and maybe, just maybe highlights uncertainty since all investment carries risk)? Happens to also abbreviate "Multum In Parvo" (Latin for "many/much in little") which is not even that far off f…

Indeed, and for different audiences, you need to be ready to present your MIP with different levels of detail. I propose we call this new process... MIP mapping. :p https://en.wikipedia.org/wiki/Mipmap

Indeed, producing (or “rendering”) a low quality MIP is easiest. :p

What I miss in the paper is any accuracy figure for glucose sensing. If this is an alternative to needles, how would the measurements compare? That is the first question one should ask. I fear we can assume that, although the approach might be novel, it can't replace needles for accurate measurement. But maybe I am overlooking the performance comparison.

Seems like it's nowhere near usable for glucose sensing

Well, I can agree that now the date on the article is 10/29/2024. When I posted this comment, it was dated 2014. I do see that internet archive has copies of the site that have the 2024 date but not from yesterday. Maybe a dead cmos battery or other time sync error changed the date temporarily yesterday. I don't have any other explanation, but I do respectfully withdraw my former opinion about the article.

A simple typo?

For me the worst part of current CGMs isn't the needle or the very thin piece of plastic it leaves behind with the probe. Rather, it's the effect on the skin under the patch and the residual adhesive. So from that perspective a watch would be cool. Indeed though, advancements in (affordable) closed loop tech matter more than where the CGM is worn.

Can you say more about the plastic left behind? Polyurethane coating on the cannula?

I mean the probe itself, which appears to be wire encased in plastic. When I said "left behind" I just meant that the probe is placed below the skin as intended, not that anything remains after the sensor is removed. This is the part that would be considered "invasive."

Why would I as a nondiabetic buy it? Out of general curiosity for my blood sugar levels?

I believe GP assumes the reader of their comment to understand that one of the types of diabetes is acquired during ones lifetime, by over-consumption of certain types of nutrition. Preventing non-hereditary diabetes could be much cheaper from a societal perspective.

There is a whole spectrum from trying to reach ultimate form to trying not to die and everyone in between.

I measure my heart rate one time for fun. It was insanely high at rest. I felt perfect, full of energy but it was completely obvious i needed to introduce rest days. I conviscated the heart rate monitor and everything was back to normal 3 days later.
