Tackling Carbs with Tech

Many people who live with diabetes avidly avoid eating carbohydrates, as historically speaking, it has been notoriously difficult to cover carbohydrates appropriately with exogenous insulins. But with access to better, faster insulins and the uptick in the use of patient-friendly technology, things are changing, and people’s diets (and their feelings of freedom) have expanded more than ever. Here are the best tech-friendly hacks to tackle the carbohydrate conundrum.

MyNetDiary

This popular app has a searchable database with nearly a million food entries for people to access and look up carbohydrate counts on the go. The company also has a separate Diabetes app that allows users to track blood glucose levels, HbA1c results, and insulin doses, to track their progress over time. If you’re looking to lose weight, MyNetDiary can create a diet plan to meet your needs. You never have to feel restricted when eating meals with family or friends, having all your carbohydrate counting needs right at your fingertips.

GreaterGoods Nourish Digital Scale

This food scale is a game changer for those who cook with lots of fresh produce, where carbohydrate counts can vary quite a bit. This scale lets the user view nutrition facts for over 2,000 foods in the scale’s built-in database, and create up to 99 more custom entries. Measure individual ingredients, track full meals, and calculate daily carbohydrate intake much easier with this digital scale.

InPen

This revolutionary device is the only FDA-approved smart pen insulin system that helps prevent users from “stacking” their insulin doses and take the right amount of insulin at the right time. This device works in tandem with a phone app, where users can track insulin on board/active insulin, personalize your doses, sync with continuous glucose monitor (CGM) or glucometer data, and share reports with others. The pen itself is compatible with Humalog, Novolog, and Fiasp, and will even dose in half units. Eating carbohydrates has traditionally been much harder on multiple daily injections, but advancements such as the InPen are making strides to make life much easier for people with diabetes.

Use Alternative Pump Boluses

If you are an insulin pump user, dosing for a high carbohydrate meal can also be difficult, especially if the meal also has a moderate amount of protein and fat (which can delay the absorption of the glucose in the meal). To handle that, try opting for a combination bolus (a.k.a. Combo Bolus or Dual Wave Bolus,  for Animas or Medtronic users, respectively; Omnipod, Tandem t:slim users will use “Extended Bolus”). This is a hybrid delivery mode: a specified portion of the total insulin bolus is delivered upfront, as a normal bolus, while the rest is delivered over a specified period of time as an extended/square wave bolus.

For example, given a 12U dose delivered as a 60/40 combination/square wave bolus over 3 hours: 60% of the total dose (7.2U) will be delivered within seconds of pressing the “deliver” button; the remaining 40% (4.8U) will be delivered equally every few minutes over the next three hours. The result is an initial dose to cover faster-digesting foods, plus an extended amount of insulin action to deal with the slower-digesting foods (which tend to be fattier or have more protein), and to prevent postprandial spikes in blood glucose. Utilizing these settings can be extremely helpful when you’re eating foods like pizza, pasta, Chinese food, Mexican food, or ice cream. Always consult with your diabetes healthcare provider before making any changes to your dosing routine.

Tandem’s Control-IQ Cleared for Ages 6-13: Automated Insulin Delivery for Children!

By Divya Gopisetty, Hanna Gutow, and Albert Cai

In exciting news, Tandem announced expanded clearance for the hybrid closed loop Control-IQ. The system is now available for children ages 6-13

The FDA cleared Tandem’s automated insulin delivery (AID) system, Control-IQ, for children ages 6-13, last week in the US. This system is designed to increase time in range for users and it does – see below for the data!

To date, the only other hybrid closed loop system available for children is Medtronic’s MiniMed 670G, which is approved for children seven years and older. Control-IQ is the first system with automatic correction boluses and no fingerstick calibration (thanks to the Dexcom G6 sensor that it uses).

Control-IQ launched in January of this year for people 14 years and older. Since then, more than 40,000 t:slim X2 pump users have upgraded their pump software to Control-IQ. We saw very positive real-world data presented at ADA this year – in the first 30 days using Control-IQ, users’ time in range increased by 2.4 hours per day, and individuals were in active closed loop 96% of the time.

At the ATTD conference in February, the trial for Control-IQ in children presented strong results. Results from that trial were used to get this week’s FDA clearance. In that trial, we learned that:

  • Children using Control-IQ spent 67% time in range, compared to 55% for children using a sensor-augmented pump. This is a massive difference that equals nearly three more hours in range each day.
  • Children using Control-IQ reached 80% time in range overnight, compared to 54% in the control group – similarly, this change is even bigger, at over six hours more daily time in range.

Control-IQ still should not be used in children under the age of six, in people who require less than ten units of insulin per day, and in children who weigh less than 55 pounds.

For more information on the system, check out Kerri Sparling’s Test Drive of Control-IQ where her time in range improvement was quite impressive! You can also Katie Bacon’s piece on one family’s takeaways (her own!) from the first month of their teenage daughter using Control-IQ.

Control-IQ: The Good, the Challenges, and Tips

This content originally appeared on diaTribe. Republished with permission.

After a month of her daughter using Control-IQ, Katie Bacon reviews the pros and cons of the algorithm and shares her family’s tips and takeaways

When the email came through in early April that our daughter, Bisi, could now download the software to run Control-IQ on her t:slim insulin pump, the timing seemed perfect. After all, our family was staying at home due to COVID-19, so we had plenty of time together to do the training and figure out the new system and how it worked for Bisi and her blood glucose levels. Plus, from everything I’d read about COVID, keeping blood sugars as stable as possible was more important than ever, and it seemed like Control-IQ could help us with that. (The Control-IQ algorithm uses data from Dexcom’s CGM to lower insulin delivery when a low is predicted and to increase insulin when a high is predicted – learn more about Control-IQ here.)

Bisi has now been on the new system for about a month, and while it hasn’t been a magic bullet and we’re still learning, Control-IQ has improved Bisi’s time in range by about 5% (and we’re hopeful that her time in range will continue to improve). Also, even more importantly, it’s improved her quality of life – and ours, as the parents who watch out for her. When I sat down with Bisi recently to ask her about the change, I got her perspective on the burden she feels diabetes has placed on her ­– and the power of Control-IQ to lighten that load. She told me that before using Control-IQ, at any given time 30-40% of her focus was on diabetes. I was taken aback by this percentage, since Mark (my husband) and I have always tried to take some of the weight for her. As she told me, “It feels demanding, like a lot of pressure, as if someone’s poking my head.” But with Control-IQ, she says, she doesn’t need to worry about much except bolusing insulin at mealtime. She has fewer highs, fewer lows, and she says she feels better physically than she did before. “For as long as I can remember, diabetes has been a main focus of my life, but it really shouldn’t be that way. So it’s been nice not to focus on it as much,” she said.

In terms of what Bisi has experienced over the past few weeks since switching to Control-IQ, I’ve divided my thoughts into the pros and cons of the system as we’ve experienced it; I’ve also included tips drawn from what we’ve learned from Bisi’s endocrinologist and DCES.

Pros of Control-IQ:

  • Graph

    Image source: diaTribe

    We’ve found that Control-IQ works particularly well at night, when Bisi isn’t eating anything or bolusing. While our nights had already improved with Basal-IQ (which did a good job minimizing Bisi’s lows), Control-IQ brings down any highs as well (see the graph on the right). I’d say that when Bisi’s pump only dealt with the lows, we still had to wake up maybe six to eight nights a month, on average – and sometimes multiple times in one night. But in the month since Bisi started on Control-IQ, we’ve only had to wake up three times. This is a big change in our quality of sleep (and quality of life).

  • Control-IQ helps keep blood sugars down during the day. As before, Bisi’s blood sugars are less stable during the day, when her activity is variable and when she’s eating meals and snacks. But now, Control-IQ raises her basal rate when she’s headed high and gives modified boluses (60% of what’s called for) if the highs are sustained. We’ve found that her blood sugar does not rise as steeply, according to her CGM, and also that it often tops out at a lower number than it used to.

Cons of Control-IQ:

  • There were a few instances where Bisi had sustained lows that were more difficult than usual to counteract with carbohydrates. These instances have all been when she’s started exercising with a lot of active insulin on board, due to Control-IQ turning up her basal rate in response to a high. Before using Control-IQ, if Bisi’s blood sugar was high, she (maybe with a reminder from me) would have to make a decision to either turn up her basal or give a correction. If she knew that she was going to get exercise in the near future, she wouldn’t do either of those things. But now they happen automatically, so she’s sometimes stuck with too much active insulin on board. It requires a different kind of thinking and a different kind of planning than before.
  • Both Bisi and I wish there were a little more flexibility in Control-IQ so she could set her own target. Bisi used to set her target at 100 day and night, and would often run at 80 or 90 while she was sleeping. With Control-IQ’s built in Sleep Mode target of 110, Bisi runs a little higher than she is used to, especially at night.

Thoughts and Tips for using Control-IQ:

  • We have found that being consistent about pre-meal bolusing is even more important with Control-IQ than it was before. If Bisi waits too long to bolus, her blood sugar goes too high, she gets more basal and an extra 60% bolus from Control-IQ, and then her blood sugar goes too low later on.
  • While it might seem like Control-IQ could enable people to be a little freer in what they eat, so far it has emphasized the benefits of eating low carb as the best way to avoid food-related spikes and insulin-related dips. No matter how good an algorithm is, it’s always going to be reactive rather than proactive, and we’ve found that the smaller the inputs in terms of number of carbs eaten, the more smoothly Control-IQ works. (I think this is partly why it tends to work better for Bisi at night, when she’s not eating anything, than during the day.)
  • Bisi’s endocrinologist validated our sense that exercise-related lows can be steeper with Control-IQ, since you tend to have more active insulin on board. Because you can’t do a temporary basal rate with Control-IQ, she suggested that we set up an alternate program with basal rates cut by 50%. If Bisi knows she’s going to exercise, she can turn on this alternate program 90 minutes to 2 hours before. Or, if she’s eating beforehand, she can put in fewer carbs/give less insulin. Either way, the trick is remembering.
  • During Bisi’s most recent appointment, her endocrinologist pointed us to a feature of Bisi’s Tandem reports that’s helpful to look at as a way to adjust settings. She told us to focus on the difference in the Logbook section between the Basal Total Delivered and the Basal Profile Setting, as a way to tell whether her basal rate at any given time should be raised or lowered; the closer the settings are to the amount of insulin that’s being delivered, the more smoothly the Control-IQ algorithm will work. She also suggested that we “Marie Kondo” (streamline and declutter) Bisi’s basal rates, which had proliferated over time, to help us see more easily where adjustments need to be made.
  • We realized that if Bisi has a random high blood sugar, particularly at night, we should assume that something has gone wrong with her pump site. Before Control-IQ, pump site failure was only one of several reasons – including the dawn phenomenon and the meal she’d eaten the night before – that her blood sugar might have gone high. This realization has helped us reduce that middle of the night detective work, when your brain is at its foggiest. If Bisi has a persistent high, the problem is most likely the pump site, not the algorithm.
  • One adjustment that Bisi has struggled with is remembering to turn off her insulin when she takes off her pump to shower or play sports. (The Control-IQ algorithm is thrown off when the system doesn’t have an accurate sense of how much insulin you have on board.) This is a work in progress for us.

Even though we still feel like we have more work to do in terms of getting the best out of the new algorithm, Control-IQ has improved Bisi’s life in important ways. As Bisi’s endocrinologist told us, “It’s not perfect, and you need to think more about active insulin than you did before. But the goal with this is to have diabetes interrupt your life less than it did before.” For Bisi, the important aim of staying in range now requires less mental effort. As she said recently when looking at her CGM graph after 24 hours of Control-IQ: “This is pure gold.”

A D-Mom’s Changed Perspective Using Basal IQ

Technology continues to make managing our diabetes easier. Continuous glucose monitors, apps for carb counting and insulin pumps have all alleviated some of the stress of managing our condition. Tandem Diabetes created Basal IQ technology, which allows us to spend less time worrying about going low and let our devices do the work. For a person living with diabetes, this means less stress and more sleep.

Basal IQ technology helps reduce the frequency and duration of lows by predicting glucose levels and suspending insulin if the blood sugar level is thought to go below 80 mg/dL or the Dexcom reading goes below 70 mg/dL. Insulin delivery will start automatically once the blood glucose starts to rise again.

Basal IQ is different than the newly released Control IQ, in that Control IQ can adjust insulin delivery, including the delivery of automatic correction boluses as needed, therefore helping patients avoid episodes of hyperglycemia. Using either one of these systems also means fewer fingerpricks, as you will no longer have to get manually take your blood glucose reading.

Basal IQ technology has given many people living with diabetes, and those who love them, a little more rest and some peace of mind. A pivotal study showed the use of Basal-IQ Technology on the t:slim X2 Insulin Pump demonstrated a 31% relative reduction in time spent below 70 mg/dL when compared with a CGM-enabled pump without Basal-IQ Technology. Important to note, the less amount of time spent at lower glucose levels did not mean more time spent at higher glucose levels. Maintaining your target range has become a lot easier thanks to Basal IQ technology.

One woman, Allison Hoffman, who helps manage her 10-year-old daughter, Becca’s diabetes, raved about the changes to her overall well-being since switching over to Basal IQ technology after relying on Omnipod for the past few years.

Here is her story:

For 7 years my mornings were absolute hell. While I would see others sleeping in, meditating, going to the gym, etc, I was a slave to Becca’s whackadoodle blood sugar swings, which would often start around 5:00 AM. My body learned to wake up at this time, and that I doubt I’ll ever be able to change.

My mornings would include me running up and down the stairs entering the bedroom, praying I wouldn’t wake her and deny her the right to sleep in, suspending insulin (audible beep I couldn’t silence), sticking glucose tabs in her mouth, often with the pay-off of a horrible blood sugar spike. I would start 95% of my days this way.

And the frustration! No adjustments to her settings were right. If I reduced her insulin she’d go high; .35 too low, .4 too high. I would wake up at 3:00 am to set a temp basal to get the amount she needed that Omnipod didn’t have as a preset-still wouldn’t work. Nothing I did was right.

Since starting on t:slim pump with basal IQ, I finally have my mornings back. It allows more fine-tuned insulin delivery and suspends when it predicts her to go low. As long as her sensor is good, and her insulin settings aren’t way off (I will always need to determine her insulin needs, it isn’t automatic), I can have a pretty peaceful morning now.

I can watch the news, or another show, or read, and my coffee doesn’t go cold. I can sit with my dog on my lap and not have to jump up every ten minutes to go deal with diabetes. I can breathe. And Becca can sleep peacefully.

I’ve made four seesaw activities for my students this morning and she’s still sleeping.

7 years of hell. I finally have my mornings back.

If you are living with type 1 diabetes and are considering a pump, you may want to look into t:slim X2 pump along with the Dexcom G6 so you can make use of the new Basal IQ or Control IQ technology. Their slogan is “live more and worry less” and I am so glad this seems to be the case for so many.

Have you tried out this technology? How has your experience been?

Co-Managing His Daughter’s Type 1 Diabetes During COVID-19

Chris is a devoted father and husband and takes care of his daughter Maggie who lives with type 1 diabetes. Chris is very active in the diabetes online community. You can follow Chris’s journey with his daughter Maggie @t1ddad on Instagram.

Chris, thank you so much for taking the time to talk to me. The COVID-19 pandemic has left us all in fear, especially for those who are elderly or have pre-existing conditions. Knowing that you fit this demographic, or have someone you love who does, adds an extra layer to this challenging time. I am sure you are anxious about your daughter, Maggie, who is living with type 1 diabetes. I see you are very active within the diabetes online community and doing your part to advocate, educate, and support others dealing with this disease. I thought it would be helpful for our readers to hear the perspective of such a dedicated dad!

At what age was Maggie diagnosed, and how old is she now? 

Maggie was diagnosed when she was 3.5 and is now almost 11.

How did your family and daughter initially handle the diagnosis?

It came as quite a shock for us. I have a first cousin that has type 1 diabetes, but I didn’t know what that meant as he lived further away, and I didn’t even see what that meant for him. Maggie was constantly drinking and urinating, and we noticed that she seemed to be losing weight. We reached out to our doctor, and he was very quick to test, then admit her to the hospital with DKA, which we are extremely grateful for his quick response. Within a month after diagnosis, we also found out we were pregnant with our youngest son as well, so there was so much going on at the same time that we had to take in and figure out as well.

Before this pandemic started, how were things going? How was Maggie’s management? Does she use any technology? Are you still very involved?

In July 2019, we came up to the 5th year of her being on an insulin pump. We had already been using the Dexcom G4 system to monitor and track her blood sugars remotely and, after doing some research, decided to upgrade to the Tandem t:slim X2 pump and upgrade to Dexcom G5. In January, we upgraded to the G6 along with the release of Tandem’s Basal IQ update. I’m so glad that these upgrades and updates all happened, so we had time to get used to them and see their benefits before all this came about.

I provide the primary care for her diabetes as my wife’s health is very poor right now as well, and I’m still quite involved in the overall monitoring and management of her day-to-day care. She can calculate most carbohydrates and give herself insulin for meals, but adjustments, corrections, etc. are all done by me. She has always been afraid of needles as well, so I also still do all the insulin pump, and CGM site changes too.

Once you heard COVID-19 was picking up speed in your area, what was the first thing you did to prepare? 

So it’s interesting. The timing of everything seemed almost perfect. I was due to refill her insulin prescription right at the beginning of March, and the doctor gave us a prescription for 3 months at a time to reduce filing fees. So before all the panic started to build, and before pharmacies began to limit the amount of insulin they would dispense, I was able to get her normal supply, which I am very grateful for. I also ordered an extra box of infusion sets and reservoirs right around the same time, but I don’t have as long of a supply for that, so I will have to watch carefully and order that a little further ahead to allow for extra time to deliver.

How is your daughter handling what is going on in the world? How did you go about explaining the severity without completely scaring her?

We have been fairly open to all our kids within reason. We try to be clear what’s going on, and there was some talk in school before it was temporarily shut down as well. Once we got word that schools were shut down (right as we were getting ready to start March break here), we had a family meeting and were clear that everyone needed to pitch in and help out so that I can keep working as much as I can to provide for the family and that everyone would need to respect each other’s space since we wouldn’t be able to get away from each other in quite the same way. We try to keep some structure while being flexible and understanding of the situation.

Photo credit: Chris

How has the stress of this affected Maggie’s blood sugars? How about her overall management?

I’m really not sure if stress has affected her blood sugars or not. I know she is not nearly as active currently as she was at school, so we are finding her blood sugars are a bit higher on average, so I’ve made some adjustments to her bolus ratios and basal rates to compensate. It’s finally getting warm enough here that we should be able to have the kids play in the backyard more, so I’m hoping that will help.

One thing we have is time. Do you plan on using this time to tackle anything diabetes-related? For example, some are using the opportunity to do basal testing. Other’s are hoping their kids get more involved with their management, etc. Or are you just taking the time to let Maggie relax and be as stress-free as possible?

The one advantage I have to her being home is having a little more control to monitor and correct compared to when she is at school. So, I’m not letting her blood sugars get quite as high before making adjustments or corrections as she would have at school. Otherwise, I have a lot on my plate, so I haven’t had the time to let her take on any more responsibility for additional things quite yet.

Photo credit: Chris

If there is one piece of advice you would offer to other parents who are going through the same thing, what would you tell them?

I think that maintaining some structure, even if it’s not school work-related is very important to keep things more ‘normal’ for my kids, and for managing diabetes as well. Keeping bedtime at around the same time, meals at fixed times etc. helps to keep the day flowing instead of it just being one long day lying on the couch with one Netflix show after another. Kids feel our stress, so hiding what’s going on isn’t going to help, but allowing them to feel free to express what they are feeling as well so we can all get through this together is very important!

If there is one positive to come out of this crisis, what would it be? I think we could all use a silver lining!

Connection & finding opportunities to love. I know for me personally, my skills, talents, and experience give me tremendous advantages and flexibility to help people. Especially small businesses and nonprofits understand that now, more than ever, they need to get clear on their message and communicate it to their clients, prospects, and those they serve. I have no clue when or if they will be able to pay me, but I continue to do what I can to help.

I have also found that myself, as well as my family, have taken the opportunity to reach out with an email, text or Facebook message, or video chat with many of our friends and family, probably more frequently then we might have even done previously in person because those relationships are so important. I hope that when we come out on the other side of this crisis, we can continue to make relationships an important part of our lives and continue to serve those around us.

Thank you so much for taking the time to talk to me. I hope you and your family continue to remain safe and healthy!

Automated Insulin Delivery: Six Universal Observations and Understandings

This content originally appeared on diaTribe. Republished with permission.

By Laurel Messer

Six universal facts about automated insulin delivery systems, and the things you should keep in mind about this revolutionary technology

Automated insulin delivery (AID) systems are moving towards the forefront of diabetes management. AID systems combine continuous glucose monitors (CGM) with smart algorithms to automatically adjust insulin delivery.

The Tandem Control-IQ system was recently cleared by the FDA, and the Insulet Horizon and Medtronic Advanced Hybrid Closed Loop systems are beginning pivotal trials. These are encouraging developments. As more systems move through the pipeline and eventually into the commercial market, important patterns are emerging in user expectations and user experience. As a diabetes nurse, certified diabetes educator and research investigator, I, along with my team at the Barbara Davis Center, have worked with nearly every AID system in the pipeline, and other systems that will never make it to market. Here are six insights we have gleaned, which seem to be universal (thus far) to all AID systems:

1. You can always beat an AID system with compulsive diabetes management

Many people with diabetes compulsively attend to diabetes care in order to achieve ultra-tight glucose ranges – and are the first to ask about automated systems. What ends up happening is that these “super-users” are invariably frustrated that the system is not yielding the same results that they were able to achieve with their own calculations and management. An important point is that many automated systems are excellent at reducing mental burden for taking care of diabetes, excellent at reducing hypoglycemia, and adequate at improving glucose levels. Humans can beat automated systems if they attend to diabetes care near-constantly. The individuals who will likely be satisfied with AID are those who are comfortable with an A1C in the 7s or above, but they want to reduce the mental load of adjusting settings and micromanaging high glucose levels. The most important question to ask is, “Why do I want to start using an automated system?” If it is to achieve near-perfect glucose levels, the system will likely disappoint. If it is to reduce the burden of “thinking like a pancreas” all the time, it may be a good option. AID will excel at the marathon of diabetes care but may disappoint in the hour-to-hour sprint.

2. Systems work best when you let them work

Using both research and commercial systems, we have seen all the ways to “trick” AID systems—entering phantom carbohydrates, changing set points, performing manual corrections, overriding recommended doses. More often than not, these behaviors lead to glucose instability – reactionary highs and lows from the system destabilizing. All systems will perform best if they are used according to user instructions. This is difficult for the individual who would prefer to micro-adjust settings or desire control over all insulin delivery. Most systems work best when users learn to trust them.

3. Give the system a chance – 2-4 weeks before deciding long term potential

It may benefit us to think about AID like a new significant relationship – it can take some time to “settle.” I mean this both on an interaction level (learning how to respond to alerts, when to intervene, when to let it ride) and on an algorithm level (allowing the system to adjust internal algorithm parameters based on usage). In addition, programmable user settings may need some adjustment in the first few weeks of use, so working with diabetes educators can be helpful for initial set-up and early follow-up.

4. Bolusing is still king

If I could go back in time, I would caution device manufacturers against any whisper of not needing to bolus with AID systems. Bolusing is the singular most important action a person with diabetes can do to optimize insulin delivery on current and near-future automated systems. This will be true until insulin action time gets exponentially faster or artificial intelligence gets better at predicting human behavior, neither of which is on the immediate horizon. In order for people with diabetes to see the best performance on any system (automated or manual), they need to bolus before carbohydrates are consumed. Specific to AID, the timing of the bolus (prior to carb intake) is especially important, as the system will automatically increase insulin delivery after an initial rise of glucose levels, so a late bolus (e.g., after the meal) could lead to insulin stacking and hypoglycemia.

5. Rethinking low treatments

Low glucose levels (hypoglycemia) still happen when using automated systems. What is different with AID is that the system has been trying to prevent the low by reducing/suspending insulin, possibly hours before the low occurs. This means that an individual may need to consume significantly fewer carbs to bring glucose levels back into range – perhaps 5-10 grams of carb at first, reassessing 15-20 minutes later. This can be difficult when wanting to eat everything in sight; however, it can reduce the chance of rebounding into the 200s after over-treating.

6. Infusion sets are still infusion sets

While AID algorithms are revolutionary, the infusion set is not. It is the same plastic or steel cannula that occludes, kinks, or inflames. This hardware limits automated systems and can very quickly lead to hyperglycemia or diabetic ketoacidosis (DKA). It is important for people using AID to recognize signs of infusion set failure – persistent hyperglycemia, boluses that do not bring glucose levels down, ketones, vomiting, etc. Knowing how to treat ketones (via syringe injection of insulin and set change) can prevent a hospital admission or worse.

I love that the diabetes community learns from its members and experiences. Check out our Barbara Davis Center PANTHER (Practical Advanced THERapies for diabetes) website for our team’s latest insights on automated insulin delivery, and tools for people with diabetes, clinicians, and engineers.
