Diabetes Vacation: Montreal Edition

As we all know, it’s impossible to take a vacation from diabetes (hence the need for some anti-burnout tips). However, certain vacation destinations and activities are better than others, a fact that I have been thinking about a lot over the past two weeks. Why has this been on the top of my mind? Because my husband and I have been doing a home exchange with a couple from Montreal, and I’ve spent our time here splitting my time between enjoying myself and worrying about my blood sugar. (Home exchanges, should you not be aware of the concept, are exactly what they sound like:  you swap homes with strangers. It’s like Air B&B, except free.) 

First of all, any time I go on vacation — or travel at all — I am shocked to realize just how much my diabetes management depends on my being at home. As a freelancer, I tend to think of my schedule as erratic, and I’m constantly struggling with how to balance the many variables that come with being self-employed. But it just takes two days away from home for me to realize just how many routines I actually have, from my low-carb breakfasts to my gym habits to how much I move around during the day.

I’ve learned that certain “dream” vacations are actually nightmares for me. Sipping frosty drinks on the beach? No thanks. Spending a week in the countryside dependent on a car to get around? Good luck adjusting my basals. But on this trip to Canada — while it certainly has come with its challenges — I’ve begun to think that Quebec during the summer is a really great diabetes destination. Here’s why: 

Bike lanes

This was one of the least scenic of Montreal’s bike paths — but you can still see how it’s set off from the main road by a concrete barrier.

1. Bike lanes. My blood sugar is easiest to control when I get regular physical exercise, ideally things that are aerobic but not too strenuous (lest my stress hormones send my blood sugar spiking). When traveling, I usually walk a lot, which is a great help. But here in Montreal, I have a different option: biking! I’d read before we got here that Montreal is considered a biker’s paradise, and I have to agree. Not only is there a citywide bike-sharing program (called Bixi) but there are bike lanes everywhere. EVERYWHERE.

And I’m not talking about painted lines on the road that cars may or may not decide to respect (or that UPS trucks may or may not decide to use as a parking spot). I’m talking about designated bike lanes (and sometimes even paths) that are completely separate from the main road. The apartment we’re staying in is right near the Old Port of Montreal (and the people we’re swapping with lent us their bikes), so the first weekend we were here we biked about 50 kilometers — ALL ON BIKE PATHS!!! — down the Lachine canal, to a beautiful park, and back. Today we went to an architectural salvage place about 10 kilometers from the house, then to the Jean Talon market, and then home — again all on bike lanes. Last night we went out to dinner at a place about 5 kilometers away . . . and guess how we got there? Even better than biking to dinner is biking back afterwards, especially when there is a free fireworks performance going on in front of you as you ride. A post-prandial ride, plus a show? Yes, please. (And there are tons of bike lanes throughout the entire province of Quebec. Check out La Route Verte for a sense of how extensive they are.) 

My idea of heaven.

2. Strawberry season. Strawberries are one of my favorite foods of all time, and we happened to get here just at the beginning of strawberry season. I cannot tell you how excited this makes me. I have been eating at least one pint per day (oh, how I love fruits that are as low in carbohydrates as they are high in deliciousness), and in addition to making me extremely happy, this habit is keeping me from eating other Quebec specialties, like maple syrup, or inch-thick slices of fois gras. My vitamin C levels at the moment are through the roof. 

3. Cheese. Not only is it zero-carb but I went to a fromagerie (that’s French for “store of amazing cheeses”) and saw an ad at the checkout claiming that cheese is good for you because it’s high in a number of vitamins. I love any country that tells me that brie is a health food. 

Cheese: 0% carb. 100% delicious.

0% carb. 100% delicious.

4. Hikes and walks. We’ve been walking a lot in the city itself (I find city vacations to be diabetes-friendly), but we also took a trip up to Charlevoix, which is an area north of Quebec known for its artisanal food producers (think more cheese and produce, plus tasty duck products) and beautiful landscapes. We found a number of great hikes and walks, including one in Tadoussac that was a very easy (though diabetes-friendly) stroll along a pine-scented trail overlooking a fjord that ended at a, wait for it, BELUGA WHALE SANCTUARY. I’ve since decided that anything involving charismatic megafauna is by default good for my blood sugar. 

5. Speaking of blood sugar, my new favorite low-blood sugar treatment: maple sugar candies. I used to love these things when I was a kid (before I had diabetes) — you know, the compressed sugar candies in the shape of a maple leaf that melt in your mouth. Needless to say I do not eat many maple syrup candies these days. But I figured that while I’m in Canada, they might be a good replacement for my Dex4 tablets and my Gu.

These are mostly gifts. Except for the candies. Those are mine.

 6. Lastly, I want to put in a plug for home exchanges themselves as a diabetes-friendly way to travel. I find breakfast to be one of the most challenging parts of traveling with diabetes, but if you’re doing a home exchange you’ve got access to a kitchen and a fridge, which means that you’ll be able to replicate your home habits while traveling. I find this to be enormously helpful in getting the day off to a good start, blood-sugar-wise. And of course, you can also cook your own lunch and dinner, which both saves you money and enables you to resort to frittatas, should the maple syrup candies prove too tempting. 

In short, Montreal (and Quebec) gets a big thumbs up from me. How about you? What are some of your favorite blood-sugar-friendly vacation destinations and activities?

Metformin and Type 1 Diabetes – An Experiment

Metformin is not usually prescribed for Type 1 diabetes, but over the past couple years, inspired in part by Mike’s experience on it (see here, here, here and here), I’ve become interested in trying it. Not only has it been in widespread use as a treatment for Type 2 diabetes since its approval in 1994, but it’s currently being investigated for potential cognitive and anti-cancer benefits as well. As Mike has asked, “Could metformin be the new aspirin?” 

The typical explanation for why metformin is not prescribed to people with Type 1 diabetes is that metformin increases your insulin sensitivity — and given that, by definition, people with Type 1 don’t make any insulin, it won’t help them. But I see two obvious holes in that logic. First, people with Type 1 diabetes do have insulin in their bodies; it’s just administered in a different way (i.e. injected subcutaneously, rather than secreted by the pancreas). And as anyone who’s struggled with the dawn phenomenon knows, people with Type 1 diabetes experience insulin resistance, too.

And second, metformin does more than just affect insulin sensitivity. It also appears to regulate the genes responsible for causing the liver to release glucose into your blood. As you may know, your pancreas and your liver work closely together to maintain a proper level of glucose in the blood. When you’ve got a lot of glucose in your blood, your pancreas secretes insulin to remove it (provided you don’t have Type 1 diabetes!). And when you don’t have sufficient external glucose – like when you’re sleeping — your liver releases some stored glucose so that your blood sugar does not drop too low. To put this a different way, insulin is what keeps a non-diabetic person’s blood glucose from getting too high; the liver (by releasing glucose stores when appropriate, triggered by the hormone glucagon) is what keeps a non-diabetic person’s blood sugar from going too low. 

I feel like I have an extremely overactive liver, which seems to take any excuse it can get to dump additional sugar into my blood stream, whether it’s needed or not. And I also seem to have difficulty absorbing the insulin delivered by my pump. So I was really excited when my doctor allowed me to start trying metformin a couple weeks ago.

When I picked up my first prescription, I decided to ask the pharmacist for some advice — namely, what sort of side effects I should watch out for, given that I’d read stories online about uncontrollable vomiting. But no, she said, in front of the group of people waiting behind me in line. The most frequent side effect is diarrhea.  That’s why they start you on a low dose. 

With that noted (both by me and my fellow shoppers), I went home and took a pill with dinner, and gave myself a bit less insulin than I’d normally take (since metformin increases insulin sensitivity it also comes with an increased risk of hypoglycemia for people taking artificial insulin — i.e. Type 1s; see below). Then I waited to see what would happen.

I’m happy to say that in terms of my pharmacist’s warnings I was lucky: no GI upset. And I’m even happier to say that starting with the very first dose, I began to notice a difference in my post-meal blood sugars. Not only did my blood sugar start to rise more slowly than normal after eating (which itself is fascinating — I’d always thought I absorbed food very quickly, but perhaps what’s really going on is that my liver is dumping glucose into my blood right after I eat), but the post-meal line on my Dexcom was much smoother than normal. 

I can’t remember what I ate for dinner the first two nights, but I can tell you this: my total daily insulin dropped from about 22 to 25 units per day to between 15 and 20. Considering that about 10 of those units are basal, that’s a really big reduction — in the most extreme case, we’re talking 5 units of bolus insulin per day. (Granted, I eat a very low-carb diet, but still.) I felt an eerie sense of ease — as if the metformin were somehow making my diabetes . . . dare I say it . . . simpler, and easier to control. It was an amazing feeling. 

That was about two weeks ago, and I’m now up to a full 1000 mg daily dose (in my case broken into twice daily 500 mg tablets). My past 5 days’ worth of totals (including basal insulin) are: 18.35u, 14.65u, 15.975u, 17u and 21.8u and my blood glucose hasn’t spiked above 200 mg/dl. (Again, I eat an extremely low-carb diet, am on a Dexcom CGM in addition to a pump, and am a wee bit obsessive — but even with all that, this is unusual for me.) When it comes to my own diabetes management, I am a Metformin believer. 

With that said, a major caveat: in addition to whatever it’s doing with my liver, the metformin also definitely increases my insulin sensitivity. I have had more lows these past two weeks than normal (which I figure is to be expected as I learn how to use it), and I have had to drop not just my mealtime boluses, but some of my basals as well. I do not recommend trying any of this without direct supervision or help from your diabetes doctor or endocrinologist, since the risk of hypoglycemia increases for people with Type 1 (it’s not a problem for people who are not on artificial insulin, which is why hypoglycemia is not typically an issue with metformin and non-insulin-taking Type 2s). In other words: this is not medical advice!

But with that said, I’m personally pretty excited. Stay tuned for further updates. And if you’ve had experience yourself with Metformin and Type 1, I’d love to hear about it in the comments section.

DBlog Week: Change the World!

It’s day one of the 5th annual Diabetes Blog week (organized by the amazing Karen Graffeo at Bittersweet Diabetes), and today’s topic is “Change the World.” The assignment? 

“Let’s kick off Diabetes Blog Week by talking about the diabetes causes and issues that really get us fired up. Are you passionate about 504 plans and school safety? Do diabetes misconceptions irk you? Do you fight for CGM coverage for Medicare patients, SDP funding, or test strip accuracy? Do you work hard at creating diabetes connections and bringing support? Whether or not you ‘formally’ advocate for any cause, share the issues that are important to you.”

Um, yes, yes, and yes! I have been sitting at my desk for about 10 minutes now staring at that prompt, wondering where to possibly begin — I find that once I start dipping my toes into anything related to the world of diabetes advocacy, it’s hard (for me at least) to resist being pulled underwater. There’s so much that concerns me, from poorly executed news coverage of diabetes, to CMS’s shortsighted competitive bidding process for diabetes supplies, to the issue of inaccurate blood glucose meters and strips, to Medicare and Medicaid’s refusal to acknowledge continuous glucose monitors as worthwhile (and I’d argue essential) tools in diabetes management. Sometimes working on this type of stuff exhilarates me — for example, the recent decision by Arizona’s legislature to reinstate insulin pump coverage for adult Medicaid recipients was thrilling. But other times it just feels overwhelming, especially when it’s coupled with the constant task of managing my own blood sugar. I feel like diabetes already is a full-time job, and it’s hard to add advocacy on top of my other full-time job (writing) and not feel a bit like I’m drowning. There’s so much to do, and always more to be done. 

With that said, I’ve noticed something personally positive that’s begun to come out of getting more involved in advocacy: a sense of community. I’ve spent the past decade or so as a freelance journalist, and while the autonomy is invaluable, it can also be quite isolating. And when it comes to diabetes, no one in my daily life — save my wonderful husband — really knows much about what it takes to manage your own blood glucose day in and day out. I’ve noticed that whenever I see pump tubing come out of someone’s pocket, or hear the familiar beep of another person’s CGM, I get a little teary — which I take to mean that diabetes often makes me feel much more alone and overwhelmed than I realize. So it’s been wonderful to begin to connect with other people with diabetes through these advocacy efforts — people who understand exactly what it’s like to act as your own pancreas, and who are passionate about the same diabetes-related issues as I am. Not only do I feel hopeful that our collective efforts are making a difference, but I also feel like I’m a part of a community — an inclusive and informal group of people all struggling through the same medical stuff, and fighting for the same type of change.

But let’s get back to the actual prompt: what is it that I feel most passionately about? I think that for me, it’s two things. First, helping other people — whether it’s insurers, reporters, CMS, politicians or the general public — understand what it’s actually like to live with Type 1 diabetes, in hopes that it will lead to better coverage for diabetes-related drugs and devices. I want there to be an artificial pancreas — a real closed loop system that alleviates some of the emotional burden of the disease and reduces complications — and I want to do all I can to ensure that all people with diabetes have access to it. I want to encourage people to participate in clinical trials in hopes that somehow, someway, some day, we actually have a cure. Diabetes sucks, and I want to do what I can to make it better.

And second, I want to write about diabetes in a way that puts other people’s subconscious experiences with diabetes into words. Diabetes is isolating. My goal is for people to read my blog, or article, or whatever, and nod their heads because they feel that way, or have experienced that thing, too.  I want to use my writing to find the humor and absurdity in life with this crappy, crappy disease, maybe even make people laugh about it a bit (even though it can also sometimes make you want to cry).  And I want to use my writing to try to help other people with diabetes — not to mention myself — feel a little less alone.

The Problem With Generic Test Strips

In concept, generic blood glucose test strips sound like a great idea. Made by 3rd party manufacturers (i.e. a company other than the one that makes your meter), they often (claim to) work with a variety of different meters, and tend to be much less expensive than their counterparts. Given that big-name test strips can cost $1 to $1.50 a pop, it makes sense that people with diabetes (not to mention insurance companies and government payers) would be eager for a cheaper solution. 

But there’s a problem: those cost savings are only relevant if the generic test strips are accurate. If they’re not accurate, then you may miscalculate your insulin dose. And if you miscalculate your insulin dose, you could die.

(To put it a different way, if a blood glucose test strip doesn’t accurately measure your blood glucose, then it’s not technically a blood glucose test strip. You might as well read tea leaves.) 

Personally, I can’t wrap my head around the fact that there is currently no system in place to ensure that test strips that have been cleared by the FDA for sale continue to meet those accuracy standards after they’re on the market. (But it’s true: there’s not.) 

I also can’t get over the fact that Medicare continues to insist that there have been no negative effects of its recently implemented competitive bidding program for mail-order diabetes supplies — despite evidence (for example, this study from the American Association of Diabetes Educators) clearly indicating that the program is restricting people’s access to blood glucose testing supplies, and pushing them — often against their will — toward problematic generic meters and strips. (Important note: they’re not allowed to do this! Scroll down on this page for more information.)

But in the rare moment when I think to myself, “Hey, Catherine. Maybe it’s not such a big deal!” something always seems to come up to snap me out of my reverie. An example of this happened just yesterday, when I received a safety notice from the FDA about Shasta Technologies’ GenStrip Blood Glucose Test Strips. (The company previously received an FDA warning letter.) If I may quote: 

“During a recent inspection of Shasta Technologies LLC, the FDA found extensive violations of federal regulations intended to assure the quality of products in the manufacturing of GenStrip Test Strips. . . At an inspection earlier this year, and documented in an April 2014 warning letter, the FDA found that Shasta Technologies did not have in place many of the requirements of a quality system. Without assurance of an adequate quality system, the FDA believes that the strips could report incorrect blood glucose levels. . . . To date, the company has been unwilling to voluntarily recall their test strips, resulting in their continued availability. The FDA recommends that use of Shasta Technologies, LLC GenStrip Test Strips be discontinued.

(Emphasis mine.)

Really?

This is not the first instance where third-party generic test strips (or low-cost meters) have been found to be problematic. (See also: this weird language from the FDA for a meter cleared last December.)  Indeed, Mike Hoskins recently did a great feature about the issue, which, given yesterday’s notice, has proved to be disturbingly prophetic. 

The company that now makes the GenStrip test strips issued a response to the FDA’s notice today, essentially claiming that the problems have been solved, those particular strips will be replaced at no charge, and that a new, rebranded version (of the same product) is soon to be launched that presumably will not have accuracy issues. Frankly, I’ll believe it when I see it — and also, as far as I can tell, this is not an actual recall, as might seem to be appropriate given the potentially deadly consequences, but rather an offer for proactive and educated customers to get replacements. 

It’s worth stressing here that the cost of test strips is obviously quite high, and that there is a need for lower-cost solutions. But cost does not — and cannot — trump accuracy. 

If you agree that accuracy is an important issue, and that the makers of 3rd party strips should be held directly accountable for the quality and accuracy of their products, please consider adding a comment to the FDA’s Draft Guidance on Blood Glucose Meters, which is open until an extended deadline of May 7th. 

For more information (and suggested comments), visit StripSafely.com (And here are my previous suggestions for other comments you might want to add, in addition to whatever you want to say about the issue of 3rd party strips.)

You can also learn more about the draft guidance as a whole by watching the FDA’s patient network’s March 31st live-chat on the subject (the first ever of its kind!) in which the FDA’s Courtney Lias and Helene Clayton-Jeter sat down with StripSafely.com creator Bennet Dunlap to have an informal conversation about what the guidance says and what the agency would like feedback from the public about. 

Also, consider leaving a review (referencing or directly quoting from the FDA’s notice) on the Amazon page for the meters and strips in question — it could help save people’s lives. (Here’s one example — but there are many other test strips made by the same company.) People need to know about these quality concerns, and (especially since the company itself is not doing a recall), Amazon is a great way to spread the word.

Again, the deadline for FDA comments is May 7th (and it only takes a few minutes). Goodness knows the 3rd party manufacturers are going to make their opinions known. Shouldn’t we do the same?

Arizona Reinstates Medicaid Insulin Pump Coverage: A Triumph in Patient Advocacy!

Great news: the Arizona State Legislature has approved the restoration of insulin pump coverage for adults in the state’s Medicaid program (known as AHCCCS)! This is partially thanks to an enormous patient-led Twitter campaign over the past few weeks to educate and encourage Arizona state politicians, and I couldn’t be more thrilled.

Sample screenshot of diabetes advocates reaching out to the AZ Senate

Background on why this is such great news: a couple years ago, Arizona stopped covering insulin pumps for adults on Medicaid. This meant that if you were on Medicaid and you either needed or already depended on an insulin pump, the state would stop paying for it as soon as you turned 21. Considering the proven benefits of insulin pumps (see a round-up of studies here — just select “clinical summaries”), this was a really unfortunate — and economically foolish — decision. Insulin pumps are instrumental in helping people with diabetes to avoid long-term complications, and their long-term benefits outweigh the short-term costs. 

As you can see in my previous blog post on the subject, there’s been a lot of back and forth going on — first the House included insulin pumps in its proposed budget, then the Senate stripped it out, then the House rejected the Senate’s budget, then they went to reconciliation, then the New York Times published its unfortunately timed piece that made it seem like insulin pumps were superfluous gadgets . . . and then yesterday, against pretty substantial odds, I got news that the legislature had included insulin pump coverage in its final budget. (And then I got all teary thinking about how amazing it is that our efforts on Twitter might have played some role in helping other people with diabetes get access to pumps.) 

Interestingly, none of the other so-called “optional” health-related amendments included in previous versions of the budget (including dental, podiatric, chiropractic and broader orthotics coverage) survived — which implies that the patient advocate Twitter campaign really made a difference in demonstrating the importance of insulin pumps.

Some important (and exciting) details: 

-there is no spending cap on the benefit

-this is not a one-year fix — the benefit will remain in place unless a deliberate action is taken to remove it. Considering that the total cost to the state is an estimated $105,000 per year (less than the cost of 6 hypoglycemia-related hospital admissions, according to the American Journal of Managed Care) I am hopeful that this will not happen.

Governor Brewer is expected to sign the budget by Friday. Technically the state fiscal year starts July 1, but its Medicaid program operates on the federal schedule (which starts October 1) — unclear how that’ll affect the start date for coverage. But sit tight: it’s coming! 

I want to extend a huge thank you to the legislatures who helped make this happen, including AZ Representative Heather Carter and Senator Dr. Kelli Ward (who are two of the people I know were the most supportive — though I’m sure there were others and I thank them as well). 

If you would like to express your appreciation on this issue, consider sending a Tweet to: 

@azhousegop @azsenategop @heathercarteraz @kelliwardaz

As well as: @andy_tobin @frankpratt @jeffdial @dgoodale @EthanforHouse @votemccomish @adamdriggs @bob_worsley @senstevepierce

And thank YOU, the diabetes community, for helping spread the word about this issue. When you combine the success in Arizona with last week’s first-ever patient/FDA live chat AND the number of insulin pump-related comments on the Medicare docket on competitive bidding (78 out of 179 are about insulin pumps!), it’s clear that patient advocates can make — and are making — a difference.

On the right is Bennet Dunlap, father of two children with Type 1 diabetes, and creator of StripSafely.com, a patient-led grassroots effort to bring awareness to the issue of glucose meter and test strip accuracy. In the middle is Courtney Lias, PhD, the Director of the FDA’s Division of Chemistry and Toxicology Devices – the division that regulates the blood glucose meters that people with diabetes rely on each day. On the left is Dr. Helene Clayton-Jeter from the FDA’s Office of Health and Constituent Affairs, which organized and coordinated the event, in collaboration with Dunlap and the FDA’s Office of External Affairs, as part of its Patient Network program.

FDA and Patient Live Chat: The Recap

As I mentioned earlier, today marks a huge day in the diabetes community’s collaboration with the FDA, the government agency in charge of regulating America’s drugs and medical devices: Courtney Lias, the director of the division at the FDA that regulates blood glucose meters, insulin pumps, continuous blood glucose meters and other diabetes-related technologies just did a live-chat with the inimitable Bennet Dunlap, creator of Stripsafely.com and tireless patient advocate. The moderator was Helene Clayton-Jeter, one of the masterminds at the FDA’s Office of Health and Constituent Affairs, which is responsible for the FDA’s Patient Network website — a cool resource which houses the agency’s diabetes web page, among many other things.

The subject? How people with diabetes can work with FDA to ensure that we all have access to safe, high quality blood glucose meters and supplies. 

From left to right: Clayton-Jeter, Lias, and Dunlap.

 

 

 

 

 

 

 

 

 

 

 

 

Here’s a quick recap:

First, if you missed the live-chat and want to see it, it will be available soon from the FDA’s patient network site for diabetes – which is also where you should go to sign up for updates on how the FDA is collaborating with patients about diabetes-related issues. As noted, it’s definitely worth checking out. 

Second, if you think this chat was a good idea (spoiler alert: I think it was an AWESOME idea), please please let the FDA know. (They like affirmation, too!) You can do so by sending a tweet to @FDADeviceInfo (and perhaps use the hashtag #DOCasksFDA). Also please comment on this post. This was a really innovative and unusual thing for them to do, and it’d be nice for them to hear our feedback. (Over 500 people signed up to watch/participate in the chat, which hopefully will also send a positive message!)

A bit more info: I have written about the FDA’s proposed draft guidance for meters and test strips before, so please check out that story (or visit StripSafely or see Mike Hoskins’ summary of the issue) if you want the background. In short, a “draft guidance” document is basically the FDA’s thoughts on what factors it will consider before deciding whether or not a particular meter (or other diabetes technology) will be cleared for sale. The last (and, incidentally, first!) guidance on the subject was published way back in 2003 — and was developed with very little direct patient input. So it’s now our chance to make our voices heard. 

The deadline for commenting has been extended to May 7th. So please, PLEASE submit your comments to the FDA’s draft guidance! You can find out how to do so (and read some suggestions of what to say) here. 

In addition to those suggestions, I also suggest that you consider requesting that the FDA do something about the accuracy of meters currently on the market. At the moment, the draft guidance is written in such a way that today’s meters would be grandfathered in, regardless of whether they have accuracy issues. During the call, Lias made it clear that if the patient community wants the FDA to incorporate more proactive language — that is, take affirmative action on today’s meters, rather than simply let them “sunset” out, we need to say so. 

I also anticipate that the FDA might get a lot of push-back about its proposed requirement for accuracy information to be published on the front of the box. This is a HUGE deal for people with diabetes, since it would a. make clear that not all meters are equally accurate, and b. provide an incentive for manufacturers to prioritize accuracy when developing new meters. It may also be possible to leverage this information to influence which meters are (and are not) covered by insurance payers. If you agree, PLEASE make this clear in your comments to the FDA. Consider including something like “I applaud FDA for its proposed front-of-box labeling requirements for blood glucose meters. This will allow customers to make educated decisions, and motivate manufacturers to improve the accuracy of their products. This is an essential part of the proposed draft guidance and should be included in the final version.”

Likewise, if you believe that the FDA should have a system to ensure that meters and strips continue to meet accuracy standards even after they’ve been cleared for sale (i.e. that there should be a post-market surveillance program), please indicate that, too! (“I believe that there should be a post-market surveillance program to ensure that meters and strips continue to meet the accuracy standards on which their FDA clearance was based.”) The FDA is trying to work with the patient community on this issue, and the more we can emphasize this issue and support the FDA in its attempts, the better.

And also: please be sure to praise the parts of the draft guidance that you like. This is not just a request from the FDA for praise; it’s essential in order to make sure that the stuff we like doesn’t get stripped out. As Lias said during the chat, “First and foremost if you agree with something in guidance document please include it. If someone else disagrees we’ll only hear their side.”

Lastly, be sure to add your personal story! It may seem strange to do so, given the formal tone that many comments can take, but the FDA really, really wants to know how the drugs and devices it regulates affect the lives of patients. So if there’s anything you wish the FDA knew about how you use your blood glucose meter, or which features are most important, or what you wish the draft guidance had said, speak up! Just as there are no stupid questions, there are also no stupid comments. Make it personal.

In the interest of brevity, I’ll end this (so you can go comment on the draft guidance — it takes two minutes!). If you have additional questions on this issue, leave them in a comment to this post and I’ll try to answer them.

In closing, I’ll leave you with these comments from the FDA’s Courtney Lias:

“It’s really been great to hear how engaged the patient community is on this issue. We [at FDA] want to get a good sense of what you want so we can try to get devices out there for you that meet your needs better than the ones you’re getting now. . . . We want patients to tell us what they want and what they need.” 

The ball is in our court. Submit your comments NOW. And let’s extend a huge thank you to StripSafely.com’s Bennet Dunlap and the FDA’s Courtney Lias and Helene Clayton-Jeter for putting together such a revolutionary and inspirational event. It’s great to be working together.

Diabetes and the FDA: A First-Ever Live Chat

Ain’t no party like an FDA party.

I’m being serious. This Monday, March 31st, the FDA’s Courtney Lias and StripSafely.com‘s Bennet Dunlap will be hosting a live chat about blood glucose meters – and you’re invited.

Lias is the director of the division of toxicology and medical devices at the Food and Drug Administration (that’s the FDA department that oversees blood glucose meters, pumps, CGMs and other diabetes technologies). As I’ve mentioned before, I’ve heard Lias speak and have been extremely impressed by her desire to engage with the patient community — she seems truly committed to listening to and connecting with the people who depend on the technologies that her department oversees. If you ask me, that’s pretty darn cool.

And Bennet, should you not already know him, is one of the masterminds behind StripSafely.com. Father of two kids with Type 1, personally at risk of developing Type 2 himself, he writes the blog YourDiabetesMayVary and is a tireless advocate for people with diabetes. Spend five minutes with him and you’ll walk away not just with a StripSafely lapel pin, but with a newfound belief in the power and importance of patient engagement. (Bennet was one of the instigators behind last week’s push to encourage Arizona’s house of representatives to reinstate insulin pump coverage for adult Medicaid recipients — an effort that, thanks to the participation of people like you, appears to have been successful!)

Bennet, too, is pretty darn cool. And he’s really, really involved in the really, really important effort to figure out a way to ensure the accuracy of blood glucose meters and test strips. This is a big issue at the moment, not just because of the issues with test strip coverage caused by Medicare’s recently rolled out (and disastrous) competitive bidding program for diabetes mail order supplies, but because of ongoing accuracy issues with meters, and the lack of a post-market surveillance program.

So here’s why I’m excited: on Monday, March 31st between 1:30 and 2:30 Eastern time, Dr. Lias and Bennet are joining together to host a ground-breaking live online chat about glucose monitors and test strips! You can read more about the chat — and sign up for it — here. To quote from the FDA’s announcement: 

  • “Do you want to learn more about the role of the FDA in the regulation of medical devices, such as glucose monitors and test strips, used in the management of diabetes?
  • Do you want to learn what the FDA is doing to increase the accuracy of blood glucose monitors and test strips?

    When you participate in this friendly online chat, you will:

    • Enjoy an informal, open discussion with a fellow patient advocate, CDRH subject-matter-expert and others in the diabetes community.
    • Learn more about the role of the CDRH, specifically the Office of In Vitro Diagnostics and its work to ensure the safety and effectiveness of medical devices used in the management of diabetes.
    • Get your questions answered about the newest FDA draft guidances, which are proposing new recommendations intended to improve the accuracy and safe use of blood glucose monitoring test systems, giving healthcare providers and people with diabetes better tools to manage blood glucose levels.

    Whether you want to just listen to the interview, ask relevant questions about the medical device regulatory process or just speak your mind on the newest draft guidance document…. you should join in the conversation.”

Translation: this is your chance to communicate with (and ask questions directly to) the FDA about its approach toward the medical technologies and devices that we rely on each day. (Note: this is not about diabetes drugs, just devices.) It’s the first event of its kind, and I encourage everyone who can to sign up  – and bring some questions!
 
Also, if you haven’t done so already, tomorrow’s chat is a great opportunity to figure out what you’d like to say in your comments about the FDA’s new draft guidance for blood glucose meters — a document which outlines the FDA’s new proposed standards that products would have to meet before being cleared for sale. The period for public comment closes April 7 and it is very important for us in the patient community to submit our thoughts and suggestions, so that they can be considered by the FDA when it drafts its official guidance documents. I’ve explained this in more detail and listed some of my own draft comments — which you can feel free to crib from — in my previous run-down of the FDA’s draft guidance; you can also learn more at StripSafely.com. According to Bennet, there are already at least 318 comments on the draft guidance comments — let’s see if we can reach 500! (Many of those 318 are likely from test strip manufacturers, so it’s especially important for us to add patient voices to the mix.)
 
In short: Monday marks the first-ever patient/FDA live chat on diabetes, and will give you a chance to ask your own questions about how the government regulates blood glucose meters and other diabetes devices, and have your suggestions heard. It’s free, it’s from 1:30-2:30 eastern, and it’s going to be great.

UPDATE: Please Help Arizona’s Legislature Protect Poor People With Diabetes

Update (Monday 3/31): Urgent action required AGAIN — please help!

My celebrations may have been too early — whereas the @AZHouseGOP made the wise decision to reinstate insulin pump coverage for adult Medicaid recipients in Arizona, their colleagues in the Senate (@AZsenateGOP) appear to be on the verge of stripping it back out. 

More specifically: the Senate president wants to strip out all the health-related amendments added by the House — including the part about insulin pumps. The full Senate may make its decision within the next day or two — if not later today (Monday 3/31) — so time is once again of the essence. (They’re not targeting insulin pump coverage directly, so we can still be positive and constructive; they’re just trying to take out what they consider to be “optional” services included by the house. Because living with diabetes is like, totally optional. ) 
 
Ugh. 
 
Anyway, apparently our efforts with the house generated thousands (yes, thousands!) of tweets to the legislators vocalizing our support — and presumably really made a difference. 
 
So can we try it with the Senate, too? I’m going to send these tweets: 
 
@AZSenateGOP Pls keep #insulinpump coverage in budget. AZ lives at stake @votemccomish @kelliwardaz @adamdriggs @bob_worsley @senstevepierce
 
And: 
 
 
Can you retweet and/or write your own? And encourage your followers to do the same?
 
Steve Pierce, fwiw, is a big supporter of pump coverage.
 
Also, we need to reach Senate President Andy Biggs (abiggs@azleg.gov) and Appropriations Chair Don Shooter (dshooter@azleg.gov), neither of whom appear to have Twitter handles. Please consider sending them an email! I’m going to say, “As a person living with diabetes, I know personally how important access to an insulin pump is in preventing devastating — and expensive — complications from diabetes. Providing insulin pump coverage to Arizona’s adult Medicaid recipients would cost about $105,000 per year, roughly the price of six total emergency room visits. At the moment AZ is the only state besides Alabama not to provide this coverage. Will you join your house colleagues in making the wise decision to reinstate insulin pump coverage for Arizona’s poorest citizens? Your constituents’ lives are at stake.”
 
Oh, and the relevant journalists (should you want to tweet them as well): 
@JimSmall @TomSprattPHX @JeremyDuda @MuckRack @HankDeanLight @Dennis_Welch 
 
I was so happy, and now am so frustrated. UUUGHH!!!
 
****
 

Update (Friday, 3/28): On Friday, March 28, the Arizona House passed a budget that restored insulin pump coverage for adult Medicaid recipients. (See the last line of this article.) This is huge news — apparently the legislators received over 200 social media messages about this issue — and I’m confident that our collective efforts made a difference. Thank you to everyone who tweeted and/or contacted Arizona’s politicians to ask for their support. If you have a moment (even if you didn’t participate the first time), would you consider tweeting a thank you to the politicians whose Twitter handles are listed below? There are still some hurdles to go before this becomes an official part of the budget, and we need to continue our encouragements (and express our gratitude). Thank you all — I’m so excited!

******

I was just alerted to an urgent matter that needs immediate help from the diabetes community. We need to tweet, email and call legislators and journalists in the state of Arizona to encourage the forward-thinking members of the Arizona House of Representatives to pass an amendment providing insulin pump coverage for insulin-dependent Medicaid recipients. 

 

This is urgent because the House is currently – as in, right this very second – considering amendments to its budget.

 

 As we all know, insulin pumps (see below for definition) are crucial tools in managing diabetes, which is a complicated, life-long, and potentially deadly disease that can lead to very expensive consequences.  The House is currently considering an amendment that would provide this life-preserving coverage for poor people with diabetes, a population whose needs are so rarely listened to – and who are the least well equipped to advocate for themselves. We need to encourage the Arizona House to do the right thing and support an amendment for insulin pump coverage.

 

Background:

 

For the past four years, Arizona – in an attempt to close a budget gap – has not been covering insulin pumps for adults on Medicaid (the federal healthcare program for the poor). This means that once you turn 21 – no matter how long you’ve been on an insulin pump, or how important it is to your diabetes management – your insulin pump and its supplies will no longer be covered, and you will be forced back to multiple daily injections. The supposed reason was cost-savings, but consider this: there are only an estimated 200 adult Medicaid recipients in Arizona on insulin pumps. According the Arizona Legislative Budget Office and Medicaid, the cost to the state of Arizona to continue providing these 200 adults with insulin pumps and supplies is an estimated $105,000 per year. (Meanwhile, the Arizona state budget recently passed by the Senate included $1 million in Medicaid coverage for chiropractic services – the only such amendment it allowed through.)

 

People with diabetes know that if you consider the cost of poorly managed diabetes, this is an extremely unwise economic decision: uncontrolled high blood glucose can lead to complications including blindness, amputations, stroke, and kidney failure (among others!). And severe low blood sugar – hypoglycemia – can land you in the emergency room within hours, if not minutes.

 

Exactly how unwise is this decision? Well, according to a 2011 study published in The American Journal of Managed Care (that looked at more than a half a million people with Type 2 diabetes), a low blood sugar that resulted in someone getting admitted to the hospital cost an average of $17,564. If you do the math, this means that if six (6) diabetic Medicaid recipients in the state of Arizona were to be admitted to the hospital because of a low blood sugar in a single year, the cost would exceed a year’s worth of insulin pumps and supplies for every adult Medicaid recipient in Arizona currently on an insulin pump.

 

 

Let me rephrase this:

 

-Arizona could either spend $105,000 per year to provide insulin pumps to all of its affected Medicaid recipients, or

-Arizona could cover the cost for SIX of those recipients to be admitted to the hospital because of low blood sugar, a possibility that is greatly increased in people who do not have the tools necessary to properly manage their diabetes

 

Which would you choose?

 

As noted, the Arizona House is currently considering an amendment to the budget that would reinstate coverage for insulin pumps for qualified Medicaid recipients. We need to help encourage them to make this happen.

 

Regardless of whether you live in Arizona, please consider tweeting this post – or simply “@AZHouseGOP – please support #Medicaid insulin pump coverage!”– to the people below. If you’re up for it, an email would be great, too. And DO IT NOW! It’s Wednesday morning at the moment, and this may be decided in a matter of a day or two. Also, if you know anyone who lives in Arizona who cares about such things, please pass this along.

Additional background info on what insulin pumps are and why they’re important:

 

-Insulin pumps are beeper-sized devices that deliver insulin, which people with diabetes depend on in order to stay alive. They allow much better and more nuanced glucose control than multiple daily injections, and are an important – and cost-effective — component of diabetes management for many people with the disease. Here’s a photo of what they look like (for more information on why pump therapy is important, please ask in the comment section – anyone on a pump would be more than happy to tell you!):

 

 

 

-Arizona and Alabama are the only two states that don’t provide insulin pump coverage to people on Medicaid.

 

-In fact, every major health plan in Arizona (and elsewhere in the country) provides coverage for insulin pumps for qualified patients. We in the diabetes community do not believe that Arizona’s poor diabetics – who are disproportionally affected by diabetic complications to begin with – should not have access to the same important treatment option.

 

-Right now, Arizona covers pumps for qualified Medicaid recipients under 21 years old. But when they turn 21, they must go back on multiple daily injections. This would be the equivalent of spending your first 21 years with access to a cell phone, and then being forced to go back to only communicating via US mail. Do you think that might have a negative impact on your daily life? How about if mistakes caused by the postal service could actually kill you?

 

Many thanks for taking the time to read this and take action. And if you’re a legislator in Arizona, thank you for considering the needs of Arizona’s Medicaid recipients with diabetes. This is a really important issue and we appreciate your support.

Why Medicare’s Attitude Toward Diabetes Could Kill Senior Citizens

I, like many people who care about people with diabetes, have a real bee in my bonnet about Medicare’s attitude toward diabetes — particularly in reference to its newly implemented national mail-order program for diabetic supplies. So much so that I actually just said “bee in my bonnet,” which I believe is the very first time in my life that I have ever used that expression. 

Why, you might ask, is my bonnet so bee-filled? Because the reduced access to high quality blood glucose meters is putting seniors’ lives at risk. Yeah, that’s right: if you love anyone who’s got diabetes and is over 65, the unintended consequences of this program could kill them. Here’s the issue in a nutshell: 

1. On July 1, 2013, Medicare implemented a mail order program for diabetes testing supplies nationwide. Translation: If you’re on Medicare and you want to get your diabetes test strips by mail, then you must use a Medicare-approved supplier for those test strips. (Important note: if you don’t mind going to the pharmacy, you can get your strips from a Medicare-contracted pharmacy — but it may end up costing you more, and is also obviously less convenient.)

2. Medicare only gave contracts to about 2 dozen suppliers (not all of which are available in all geographic areas, so your choice of where to get your test strips is limited). Perhaps even more importantly, it reduced the reimbursement rate for diabetic test strips by about 72 percent. This was meant, obviously, to reduce costs. But this rate was so low that it can’t pay for strips from some of the big test strip makers — like Abbott, Roche and Accu-chek. As a result, suppliers are switching many Medicare recipients — often against their will — to generic meters and strips instead. (Really important note: They’re not allowed to do this! If you’re on Medicare, you have the right to stay on the meter prescribed by your healthcare professional. For more details, scroll down a bit on this page.)

3. Blood glucose meters are not interchangeable. This is partly because different people — particularly seniors — have different needs (for example, you might need a meter with large type, or a meter that speaks to you in case you have poor eyesight and can’t see the number, or a meter that is particularly large or small, etc), and partly because . . . 

4. . . . Diabetes test strips and blood glucose meters are not all equally accurate. This might come as a surprise to many people — I for one had previously assumed that a meter is a meter is a meter — but there are many meters on the market that do not consistently give accurate results, and generic meters, particularly those produced overseas, are particularly problematic. (Read my article, Why You Should Worry About the Accuracy of Your Blood Glucose Strips, for more information — as well as my post, Why You Should Be Depressed About the Government’s Attitude Toward Diabetes.) Guess which meters the Medicare-approved suppliers are pushing on seniors? The cheapest ones possible — i.e. the very generic meters that are the most likely to be inaccurate. What’s more, there is also no program in place to make sure that meters and strips that get cleared by the FDA continue to maintain the same levels of accuracy once they’re on the market. (For more on this issue, check out StripSafely.com.) 

The dangers posed by inaccurate meters and strips should be obvious: if you use a meter to dose insulin, and if your meter is wrong, then you can take too much insulin — and you could die. Senior citizens need access to accurate blood glucose meters. (As do ALL people with diabetes!)  This is not a push for a particular brand or company — if we can get accurate meters for less money, that is great. But cost reduction should not threaten the lives of the very people it’s meant to help. 

I’m going to write an article about the American Association of Diabetes Educators’ recent investigation of the competitive bidding program for diabetic testing supplies (spoiler alert: suppliers are not providing what they promised). But for now, I bring the subject up because Manny Hernandez of the Diabetes Hands Foundation/TuDiabetes just tweeted an article that I very much hope the powers that be at the Centers for Medicare and Medicaid Services (CMS) pay attention to: an article from US News and World Report titled “Elderly Diabetic Patients on Insulin Most Vulnerable to Low-Blood-Sugar Trouble.” If I may quote: 

“A new look at diabetes patients in the United States who use insulin and wind up in the emergency room with low blood sugar shows the dangerous scenario is more than twice as likely to happen to those over 80 years old.

“Not only that, elderly diabetes patients are five times more likely to be hospitalized than younger patients as a result of the low-blood-sugar episode, the study found.

“‘Managing insulin can be a complex endeavor,’ said study author Dr. Andrew Geller, a medical officer at the U.S. Centers for Disease Control and Prevention. ‘We knew it would cause a lot of emergency-department visits for adverse events, but we didn’t expect the full severity of these events. Almost two-thirds involved things like passing out and seizures.’”

Geller and his colleagues “were able to estimate that just less than 98,000 emergency-room visits occur in the United States each year due to insulin-related low blood sugar,” and that “almost 30 percent of those emergency-room visits resulted in hospitalization.”

Putting aside the obvious health risks posed by severe hypoglycemia, I’d note that 98,000 emergency room visits per year likely cost the government (and health insurers) a hell of a lot more than the price of an adequate supply of accurate blood glucose meters and strips. 

Judging from comments I heard from CMS at the Diabetes Technology Society’s meeting in September,  however, I anticipate that CMS would interpret the findings of this study quite differently — namely, they’ll see it as evidence not that blood glucose meters need to be accurate, but that fewer seniors should be on insulin.

What this interpretation would miss is that these are two separate issues. We in the diabetes community are not talking about whether a senior citizen should or should not be on insulin. That is a choice that should be left to the person and his or her doctor. What the diabetes community is saying is that a blood glucose meter is only a blood glucose meter if it is accurate. If it is not accurate, then it cannot be used to dose insulin or “make therapy adjustments,” if I may quote CMS itself. And if a meter cannot be used to “make therapy adjustments,” then it cannot be considered to be Durable Medical Equipment (DME) and therefore cannot legally be covered by Medicare

If you think this issue is important and would like your voice heard, here’s some good news: the FDA is accepting (and encouraging) comments from the public on its new draft guidance for blood glucose meters. (FDA is not responsible for competitive bidding — in fact, the FDA appears to have quite an enlightened view toward diabetes devices — but since CMS often looks to FDA guidance to make decisions, it’s important for us to make our concerns and suggestions known to the FDA.) Check out the sample comments the StripSafely team and I put together — complete with easy-to-follow instructions and links — here. (Pay particular attention to the suggested comments about “durable medical equipment,” since that is the part most likely to impact CMS and the coverage issues brought up in this post.) 

I also recommend that you consider sending a letter in support of calling a Congressional hearing to ensure that the meters provided under Medicare’s competitive  bidding program live up to the accuracy standards of the FDA. We’ve put together a sample letter — again, with instructions — here. It’s really easy, and could make an enormous difference.

Lastly, if you or your loved ones experience any sort of adverse effect of Medicare’s policy toward diabetic testing equipment — whether it’s a problem with the meter or test strips themselves, or a problem getting access to them to begin with — I strongly encourage you to complain directly to CMS. You can do so via this link. Heck, I recommend filing a complaint regardless, pointing out the issues raised here and on StripSafely.com. And while you’re at it, why not contact the Inspector General of Health and Human Services, the government agency responsible for investigating Medicare Fraud. Point out that if Medicare is reimbursing suppliers for testing equipment that can’t be used to make therapy adjustments — and that therefore cannot be considered to be Durable Medical Equipment — then those suppliers are defrauding the government by receiving reimbursements for equipment that should not technically have been covered. (More on this line of thought later.) 

If you tweet this article, or anything about it, please use @medicaregov and @OIGatHHS (the inspector general) so that they are aware of our concerns. And if you can throw in a little @stripsafely as well, that would be superb. 

Thank you for reading this. If we work together, we may be able to save people’s lives.

Minimed 530G with Enlite Trial, Threshold Suspend

Last week I started a trial of Medtronic’s latest insulin pump and continuous glucose monitoring system, the Minimed 530G with Enlite. (See my previous post here.) I thought I’d devote today’s post to what’s arguably the most exciting part of the new system: threshold suspend. 

As those of you who have been keeping up with the work toward developing a closed-loop insulin delivery system (the so-called Artificial Pancreas) know, threshold suspend is the first step in the long journey toward that goal. (You, like me, may also have been irritated by the marketing that surrounded the 530G and used the word “artificial pancreas,” since it was picked up and oversimplified by the news media to suggest that this system actually is an artificial pancreas, which it is most definitely not.) 

Threshold suspend, which has been available on Medtronic’s Veo pump/CGM system in Europe since 2009, means that if your blood glucose reaches a certain predetermined level (anywhere from 60-90 mg/dL), your insulin pump will alarm, warning you of a potentially dangerous low. If you respond to the warning, nothing will happen.  Minimed 530G with Enlite Trial, Threshold SuspendBut if you do not respond to that warning, the pump will shut off basal insulin delivery for two hours. (Then it will go on for four hours, then off for another two, etc, till someone clears the alarm.) The idea is simple: if you’ve got a low blood sugar and are not responding, the last thing you need is more insulin. 

When I set up my 530G system last week, I was hoping not to have to experience the benefits of Threshold Suspend firsthand. I’m lucky enough to never have passed out or been sent to the hospital as a result of a low blood sugar, and thanks to my CGM, usually am able to stave off bad nighttime lows. So I was surprised when I found myself roused from sleep my first night on the system by two-tone alarm of my pump going off, and the message on its screen that said Threshold Suspend. A quick scan of my body confirmed what it was suggesting: my heart was racing, and I felt shaky. My blood sugar was indeed low. And whereas I’m normally able to correct for a low with two glucose tablets (even that sometimes sends me too high), that night I took five glucose tablets and never had a spike above 130 mg/dL. In other words, I’m glad that it went off. 

With that said, I’ve also found some things about the Threshold Suspend function to be unsatisfying/annoying. First, it isn’t predictive, meaning that it will only shut off once you’ve already reached your predetermined target (the next generation will hopefully have this capability). But second, there are some aspects of Threshold Suspend that I worry will limit its use. For example, you can only set your limit from 60 mg/dL to 90 mg/dL (kind of odd, since you can set other aspects of the pump as low as 40 mg/dL). I have mine set at 60 mg/dL, as low as it’ll go, but I don’t think it’s low enough: I often touch 60 mg/dL over the course of the day, and I don’t consider those lows to be emergency situations, since I’m alert and easily able to correct it. I would like to have the option to set it lower.

Second, I would like to be able to create two targets for Threshold Suspend: one for the nighttime, and one for the day (and a temporary snooze function). I say this because, as mentioned, a low of 60 mg/dL when I’m alert and awake is not an emergency situation. But the pump’s Threshold Suspend function INSISTS that it’s an emergency. The alarm does not start with a vibration — it goes straight into full on alarm mode. This means that if you are in a situation where you don’t want to risk having a siren emanate from your body — say a meeting or interview or yoga class — then your only option is to turn off Threshold Suspend. That might be fine for the moment, but it puts you at risk of forgetting to turn it back on for the times you really do need it, particularly before you go to sleep. And if the sensor is giving you an inaccurate reading — which is quite possible on any CGM system — then it’s even worse: you can have your pump start to go bat-sh*t crazy on you when you aren’t even low. 

All this brings up a point that I predict I will be reiterating throughout this trial: I wish that there had been more patient input in the design of the 530G, particularly when it comes to alarms. I do not know what type of trials were done before the system was submitted to FDA for approval, but I cannot imagine following a real person with tightly controlled diabetes around for three days and not concluding that the current limits for Threshold Suspend are too high, and that you should be able to set different limits for different times of day (and that the nighttime alarm should be louder — by the time I woke up, insulin delivery had already been suspended). As it is now, I really do worry that the annoyance of having a siren go off every time my blood glucose hits 60 mg/dL is eventually going to make me either turn it off (and forget to turn it back on), or turn it off entirely. And that would defeat the main added benefit of this particular pump.

With that said, I think that the Threshold Suspend feature of the 530G system is a great advance in diabetes care. I also think that integrated pump and CGM systems — especially those that can ward off potential dangerous lows — are essential for people with diabetes, and I believe that insurance companies and payers like Medicare should cover them. That’s probably the most important message of all.
