Berlin Diabetes and Technology Meetup

Hello All,
Summer is almost here!

After a brief hiatus we are planning to start a new series of Diabetes and Tech Meetups at the brand new creative workspace ‘5pace’ ( in Berlin, Kreuzberg, at Paul-Linke-Ufer 42.


As before, these meetups will bring together the Berlin design and technology community to meet and discuss apps, hardware, analytics and related topics in the diabetes and other parallel health spaces.

The event is planned for Wednesday June 28th.

Speakers for this meetup include:

-Berlin startup who are working in predictive analytics for diabetes
-Diabetes Lab pilot-Kevin Röhl will be presenting on the outcomes of an experimental 3-month project that brought T1’s and Roche designers together to innovate and ideate on new diabetes products.
-And of course lots of networking around diabetes, health and technology.


please sign up early, and watch your mailbox for announcements soon!

ATTD Paris 2017 reflections

ATTD Paris 2017 reflections

Smart Insulin pumps

AP no bolus

AP no bolus

Just got back from ATTD in Paris, and am still coming to terms with several days of immersion in the current state of diabetes technology.  The biggest takeaway is that the “Artificial Pancreas,” or the “Closed Loop system,”  or the “Hybrid Closed Loop system,”  or perhaps the “Smart Insulin Pump,” well whatever you want to call it, it is here.  Of course Medtronic has struck first, with an insulin pump that automatically adjusts Basal insulin rates, which is especially useful for night  management.  Everyone was showing slides demonstrating that their version was performing quite well.  Of course most of these systems still require the user to manually input meals so as to get extra insulin.  Though even this is being improved. There were examples of fully automated systems, while still far from perfect were offering reasonably good control.

Psycho-social aspects of diabetes management

ATTD is mostly about technology, and was glad to see some appreciation that the users of these systems should be considered. There is at times a tendency for technologists to see the human as the host of the algorithm, so luckily a few presenters addressed human factors. The diabetes illness Identity dimensions was particularly intriguing. The presenter A. Libermann noted that MDI users tended to see diabetes as more enriching and on the left side of the graphic, while pump users tended to be more on the right hand side and more engulfed by diabetes.  This would be an intriguing study, as many of my tech crazy friends are still using MDI.  Although on the bus to the airport I got a very convincing talk from a user of the Loop system with uses a Riley link to connect a Medtronic pump and a Dexcom CGM to provide impressive control.  Think it might be time for me to start working on one of those!

helping PWDDecision Support systems

There were quite a few presentations on digital decision support systems, although I unfortunately missed the Medtronic sugar IQ presentation. Sounds exciting, will post slides when I get them.

This slide shows a Venn diagram for a HCP oriented systemIMG_2751.

This Poster from the PEPPER project at Oxford-Brookes shows their work on a case based reasoning approach for diabetes management advice.  They will be starting trials soon, so I eagerly await the results.



The slide titled replaying data showed another approach, feeding back acquired glucose results to make predictions for future results. And there was also an insulin dosing adjuster which appeared to work as well as a diabetes expert. Take that for what you will.IMG_2793IMG_2795

Of course such shows are never complete without a few highly dubious claims.  My favorite was for another non-invasive CGM. haven’t fact checked this, but just have to same I am skeptical.

First ‘Artificial Pancreas’ Approved! And why autonomy matters more than ever.



Today I saw in Google news, in my LinkedIn feed, and all over the net that Medtronic just got the first artificial pancreas (AP), well of course more properly a closed loop system, approved by the FDA. This is of course great news! A virtual cure for diabetes (at least if you are willing to constantly monitor and change sensors, calibrate the device, keep the insulin chamber filled etc.)! It has been a long time coming, and will no doubt help many attain better diabetes management, avoiding serious short and long-term complications. This could be fantastic for young children, the elderly, and those who struggle to maintain glycemic control. That being said, in a broader sense I have my concerns. Not because it is a bad idea, but because of the larger context of lifestyle related illness, financial profit, and the role of technology in our lives.

Health as a person with diabetes is much more than getting the right amount of insulin. It is about having a healthy lifestyle, the same as for every living creature on the planet. People all over the world are suffering from lifestyle-associated illnesses related to stress, poor diet and insufficient exercise. Pharmaceuticals are not the solution to all these problems, even when intelligently delivered, and I doubt they ever will be. I have concerns that systems like the AP, especially for those who have lifestyle related illnesses like T2 diabetes could detract from the urgent need to have more walkable cities, healthier foods, more active jobs, and a more sustainable society in general.

Putting the whole world on insulin not to mention anti-depressants, opiates, activity suppressants, etc. do nothing to address the root problems. Study after study has shown lifestyle interventions to outperform medications in treating T2 diabetes and aspects of chronic depression. While the Medtronic AP is being marketed initially to the T1 community, the big money is in T2, and that strategy is already being pushed. We are talking an over $6k device, thousands of dollars a year of sensors and cannulas, and thousands of dollars a year of ever more expensive insulin. Not to mention what Glucagon will cost, when the dual hormone AP gets approved. I fear a society of people slaving away at machines, so they can pay for their complex mixes of injected hormones, antibiotics, and mood enhancers. Some might argue we are already there.

I am not against tech, and  as a person with T1 diabetes, I depend on it every day. However, as we develop technologies that integrate deeper into our body processes, there is much to consider. E. M. Forster over a hundred years ago wrote “The Machine Stops.” This dystopian short story proposed a world where inhabitants communicated through video and text messages instead of personal contact, and had all their physical needs met through a smart environment. In time they came to worship the machine as a god, and perished in mass when it stopped functioning.

So is the AP a great leap forward? For some people this device will be life changing. Who knows, in time I might be using one myself. But we must be careful to consider the implication of what we are doing, and to not fix our problems by creating even greater problems. Those of use who seek to design such systems have the responsibility to consider how to preserve user autonomy as we ask users to turn over daily decision making to computational devices.

So onward with technology, and thanks to Medtronic for bringing the first AP onto the market, but we must not become so enamored by what we can do, that we lose sight of where we want to go.

Empowerment and Self-Management of Diabetes

Martha M. Funnell, MS, RN, CDE, and Robert M. Anderson, EdD

Just came across this great article from 2004,

From a patient perspective, this should be mandatory reading for every doctor working in diabetes.

Amazing how many don’t understand the lessons in the writing.
