An experimental OJ

In a conversation about a recent article about my fully-closed looping a question was posed to me about how my body (and AID system) would react to something like an unannounced fruit juice. My results have to be influenced by my diet to some extent. Fruit juice is something I don’t consume much of. And …

Progressing through Hybrid and “Fully” Closed-looping

I’ve done articles like this in the past, comparing my clinical results over the years. But I’ve just hit what feels like another milestone, so I’m going to re-do it using my current reporting tools. I’m going to show data from four points in time: 2017, when I’d only recently started using an Automated Insulin …

Clinical research news

You may have seen me refer in the past to some of the clinical trials I’ve been involved in. Now it’s time for the next phase of news! The “Baker AAPS” trial In 2019 I started working with the Baker Heart & Diabetes Institute on a clinical trial of the safety and efficacy of the …

Insulin timings (2022)

Different insulins have effect (and get used up) at different speeds, and modelling this is important for accurate calculation of subsequent insulin doses. Some automated insulin delivery (AID) systems try to determine this themselves (e.g. CamAPS has nowhere for us to tell it which insulin we’re using) and some (e.g. Medtronic and Control-IQ) seem to …

Quinquennial looping!

What’s a quinquennial? A 5-year anniversary. Yes, it was a whole 5 years ago I finally set up my “DIY” closed-loop. I’m obviously still using it, although there’ve been lots of changes along the way. Both in terms of improvements in clinical results and in terms of quality of life. What’s changed in the technology? …

May 2022 data snapshot

Last month I mentioned that I had modified the parameters I was using for the insulin activity/IOB modelling in my AID/loop system. Specifically, for Lyumjev and for Humalog I’m now using 9 hours in the exponential IOB model. I showed statistics from two 4-week samples of Lyumjev, and then a 7-day sample using this timing …
