DAVID MENDOSA: Diabetes and Cracked Fingertips: Everyone’s Hands Need Help

Tuesday, March 18th, 2008

People with diabetes are like everyone else, only more so. This realization has been slowly growing in my mind as I began to appreciate that while we talk all the time about how those of us with diabetes need regular exercise, good nutrition, and weight control, everyone needs that too.

Even the complications of diabetes are more intense manifestations of what anyone may experience. For example, the problems that we often experience with our skin are similar to what just about everyone experiences, although maybe we experience them more often or more severely.

High blood glucose levels can sure make wound control more difficult. But I know from my own experience that even as I have controlled my blood glucose, my hands can get just as dry and cracked as they ever were. Maybe more so.

Maybe it’s the typical dryness of winter. Maybe it’s the special dryness where I have lived for the past three or four years. Maybe it’s because I’m more active outside now. But it’s certain that my hands need help.

And everyone’s hands need help. My dermatologist, Yan Isabel Zhu, emphasized that to me last month when she checked me for skin cancer, as she does at least once a year.
“We all need to apply a thin layer of hand and skin cream every time we wash our hands,” she told me during a recent check up. “In all seasons and in every part of the country.”

Applying hand and skin cream every time I wash my hands has been a challenge. I’ve been a good boy. I wash my hands regularly — including every time I go to the bathroom or come into my place from outside. That avoids a lot of problems.

But it causes problems too. My hands get awfully dry and cracks often develop.

Apparently these “split fingertips” are an awfully common problem among people with and without diabetes alike. A recent column in the “People’s Pharmacy with Joe and Terry Graedon” brought out a large number of reader suggestions.

I don’t doubt that we have many good ways to prevent or at least minimize these cracks or split fingertips. But we have to remember to follow my dermatologist’s advice to apply the cream every time we wash our hands. And even when we don’t.

As I write this I have a couple of split fingertips that make typing a bit painful and invite infection and inflammation. I have been applying hand cream every time I washed my hands, but I just came back from a backpacking trip where, although I wasn’t washing my hands, I exposed them much more to the elements than usual, and I failed to apply it regularly.

The difficult part of all this for me is which hand and skin cream to use. While we have many to choose from, I’m guessing that it’s best to avoid any of them that contain potentially harmful chemicals called phthalates and parabens.

A surprising number of hand and skin creams, including some formulated especially as “diabetic skin” therapy, contain parabens — under several names, such as methylparaben, propylparaben, ethylparaben, and butylparaben. On the recommendation of my favorite Certified Diabetes Educator, I now avoid all such products.

But we have many alternatives and even vegetable oils, like pure coconut, can help when we have nothing else on hand. Still, skin care products unfortunately are greasy and take too long for inpatient people to work into their skin.

My CDE gave me a free sample of one greasy product that I can tolerate when I need it. After cracks have developed in my fingertips, I can put up with the greasy inconvenience of one such product, Aquaphor Healing Ointment from Eucerin because it works so well for me.

But for everyday use I prefer a different product. Dr. Zhu, my dermatologist, recommends and gave me samples of a skin cream that lacks both the troubling chemicals and the grease. It also mercifully free of any dyes and fragrances.

What she recommends is “Vanicream Moisturizing Skin Cream.” While she told me that Costco has it at the best price, I also found it at my neighborhood pharmacy.
Now I keep a tube of it on every sink in my place to remind me that cream follows water. It’s less confusing that way.
It’s great — when I remember that like everyone else that I need to use it.

DAVID MENDOSA: Setting Slack Standards

Sunday, March 9th, 2008

We live in a culture of low targets,” writes Hana, one of my regular correspondents in England who has diabetes. For example, her nurse told her that that walking for half an hour three times a week was enough exercise to make a difference, and it doesn’t have to be fast walking. “I do a lot more than that,” she says.

I agree with Hana. Like Western culture as a whole, the medical establishments in the U.S., the UK, and probably most of the rest of the Western world set the bar far too low for people with diabetes. In the U.S. the American Diabetes Association sets the standards that count.

Every year the ADA looks at the goals it thinks that those of us with diabetes should reach and summarizes them in Standards of Medical Care in Diabetes.” It is gradually setting higher standards, and not all of the standards that it sets are slack, particularly those for cholesterol and blood pressure control.

But many of us who have lived with diabetes for many years think that in four areas the standards are too lax, and that if we personally don’t choose to set the bar higher we won’t have as many years left.

A1C
No standard is more important than our A1C level, which measures our average blood glucose over the past two to three months. The ADA says that generally its goal for non-pregnant adults in general is less than 7 percent.

Considering that the average A1C level of American adults with diabetes is between 8.5 and 9 percent, as an ADA doctor once told me, it’s the right direction. But is it enough?

that it’s up to 6.2. The Accu-Chek meter company The answer to that question is what is an average level. The large UK Prospective Diabetes Study saidsays that it’s 5.0. Dr. Richard K. Bernstein told me that it’s about 4.5, where he has been able to keep his own level for many years in spite of his type 1 diabetes.

Personally, I have recently been able to get my A1C level down to 4.6 to 5.4 in different tests from different labs recently. I’m pleased, because it’s clear that the closer we bring our levels to normal, the fewer complications we are likely to get.

New studies are coming forth regularly that show the closer our A1C levels are to normal the better. Just this month a study in the top medical journal, Lancet, demonstrated that more than 60 percent of retinopathy cases were among patients with levels below 7.
Then, why set the goal at 7 percent? The ADA says that it’s because of the greater problem with hypoglycemia when we shoot for a normal level. Certainly, if you are taking one of the diabetes medications that can make you go hypo — specifically insulin or one of the sulfonylureas — you need to be careful. Otherwise, we have no reason not to shoot for a normal level.

Exercise
Hana’s nurse in suggesting that all the exercise she needs is 90 minutes a week is indeed stetting a low standard. Even the ADA aims higher. It recommends that those of us who can do it get 150 minutes of moderate-intensity aerobic physical activity a week as well as resistance training three times a week.

But even the U.S. government’s current recommendation for adults to lose weight is 60 to 90 minutes of exercise on most days of the week. That works out to up to 360 minutes of exercise a week.

Dr. Alan Rubin, an endocrinologist in San Francisco and the author of Diabetes for Dummies told me that he personally gets at least 90 minutes of exercise per day and that the only way his patients have been successful in losing weight is getting several hours of exercise every day.

Taking heed, I make sure that I get about 14 or 15 hours of exercise every week. I needed it to lose weight and to maintain that weight loss.

Weight Loss
When I started taking Byetta in February 2006, I weighed 312 pounds. Today I weight 158. That’s almost a 50 weight loss.

The ADA, on the other hand recommends that, “For obese individuals, a modest weight loss of 5 to 10 percent of body weight may be indicated.”

If I had paid attention to the experts, I could have hoped to reduce my weight by 31 pounds and would weigh 281 pounds today. On my 6′ 3″ frame I would still be obese with a BMI of 35.1, instead of having the low normal BMI that I have today of 19.7.

Carbohydrates
Of all of the ADA’s lax standards, nothing disturbs some people with diabetes more than its recommendations that we eat a lot of carbohydrates. It recommends that we get 130 grams of digestible (net) carbohydrates per day. The big beef of most detractors of a low-carb diet is that it’s too difficult for us to follow.

Dr. Bernstein stands at the low-carb end of the spectrum. His recommendation is essentially about 42 grams of carbs per day.

The jury’s still out on this one. But the remarkable new book, Good Calories, Bad Calories, by Gary Taubes, finally persuaded me that a high fat-diet — in other words one that makes a low-carb diet possible — is safe for my heart.

The common complaint about the ADA’s lax standards is organizational inertia. But that’s not fair.

Diabetes can be overwhelming, especially when we get our diagnosis and realize that we have to totally change the way we live. The ADA certainly realizes that if it told us to change our lifestyles this drastically, even more of us would go into denial and essentially say, “Shove it.”

If the ADA had set honest standards, it would be little like telling someone to eat an elephant, my favorite Certified Diabetes Educator tells me. “Initially seems overwhelming and impossible,” she says. “But if you do it one bite at a time, especially by setting smaller more easily attained goals, you’ll get there eventually.”

But those of us who have lived with the disease for several years know well that we feel better and can expect to live longer, healthier lives when we set our own standards much higher. For us, getting to these goals eventually means getting there now.

DAVID MENDOSA: The Simple GlucoMON

Sunday, March 9th, 2008

All of us can use a little help in managing the complexities of our diabetes. The very young and the very old sometimes need a lot.

Do you need to make sure that your child or parent has his or her blood glucose under control? Short of hovering over them all the time, you can ask them to send their test results to you or their doctor.

Unless you have a GlucoMON, that wouldn’t be easy. But with the GlucoMON it is unbelievably simple.

I know how simple it is, because I finally got my hands on one after writing about it for years.

The GlucoMON has just become commercially available. In the meantime the company, Dallas-based Diabetech, focused its efforts on perfecting its behind-the-scenes software inside of carefully controlled clinical trials while also making sure they took the steps to comply with various Food and Drug Administration regulations. Their commercialization efforts also took time, as they recently upgraded their technology to run on the GSM/GPRS wireless networks, which run most of the world’s cell phones. This new device and their commercial offering are classified in the same category as Microsoft’s Health Vault platform and a forthcoming offer from Google.

The amazing thing to me is the fact that the software is indeed behind the scenes. I hate testing software, mostly because it takes so much time to install and then to learn. And then there are always bugs. And then you have to keep it updated.

But the GlucoMON software isn’t even on your computer. It works in a similar way to Google’s “cloud computing” applications like Gmail and Google Docs that I completely rely on nowadays.

GlucoMON even does Google one better. To use it you don’t need an Internet connection. Or even a computer. Or a phone line. And soon you won’t even need electricity for it.

Currently, the device relies on electricity from a standard electrical outlet for its power. But Diabetech is a finalizing an optional mobility kit that includes a car charger and a battery pack.

The GlucoMON is an automated, long-range wireless blood glucose data monitoring and transmittal system. “Think of us as a wireless phone company that just does diabetes,” Diabetech founder and CEO Kevin McMahon told me years ago. The key, he said, is not just that it is wireless, but especially that it is automatic. “It requires no training. There are no buttons to push or computers or Palm Pilots to attach.”

While the name GlucoMON obviously stands for glucose monitoring, it actually isn’t one. Currently it works with LifeScan’s OneTouch Ultra. Kevin tells me that his company is working out licensing deals with the other major meter manufacturers.

“The data are transferred over our network and are stored in the secure patient record in our GlucoDYNAMIX server software,” Kevin says. “The data include the patient profile, patient-specific rules, alerts, reminders, reports, and education.”

Since the GlucoMON is hardware, I dreaded the setup even more than if it were software. In the event I couldn’t have been more surprised.

I plugged it in to an electrical outlet, set up the little antenna on my desk, checked my blood glucose with the Ultra, and then plugged the Ultra into the GlucoMON. It must have taken at least 60 seconds.

By that time the service had sent me an email confirming the result. Normally, of course, that message would have gone to the parent of the young child or the child of the aged parent.

The GlucoMON has to be especially attractive to parents who have children with diabetes in school. Typically, a family will find a place at school that is convenient and which usually coincides with where the child checks his or her blood glucose before lunch, which generally is the most critical time during the school day because of insulin dosing then. Or the child may carry it in his or her backpack and just plug it in when need. Then, he or she might bring it home on weekends to support sleepovers or trips to Grandma’s. It weighs less than 7 ounces.

The GlucoMON can support shared users too, Kevin tells me. “I don’t know any other device that can support this model.”

The company offers discounts for second users of a shared GlucoMON in the same family. Another option is its school plan where three or more family can use a shared GlucoMON.

For my purposes, even more impressive is the automatic log sheet that the system generates and sends out daily. I have seen and used lots of different log sheets and in fact link some of them on my website. But none of them hold a candle to the GlucoMON’s report, which is not only automatic but also logs blood glucose results in hourly time-slots, highlights highs and lows, and makes trend analysis simple.

DAVID MENDOSA: “Fitness and Fatness” by David Mendosa

Monday, February 4th, 2008

We all know that diabetes is a risk factor for heart disease, and we do our best not to collect any more of these factors. Of course, it’s better not to take any other risks with our hearts. But what’s worse, to be fat or to be unfit?

I didn’t know the answer until I read this study in December’s issue of Medicine & Science in Sports & Exercise, which is the official journal of the American College of Sports Medicine. Nine professors and who knows how many members of the Look Ahead Research group somehow got together to write, “Fitness, Fatness, and Cardiovascular Risk Factors in Type 2 Diabetes: Look AHEAD study.”

One of the study’s authors, Steven Blair of the University of South Carolina, was kind enough to send me the full-text of the article. You can read the abstract online.

This huge study included 5,145 people with type 2 diabetes, all of whom were either overweight or obese. The average age of the people in the study was 59. Not surprisingly, the heaviest people in the study were also the least fit.

The researchers used both the body mass index (BMI) and waist size to determine how fat the people in the study were. Then, the researchers graded the cardiovascular fitness — not muscle strength — of the participants after they worked out on treadmills.
Now, after carefully studying the report, I understand why I didn’t know whether it was better to be fit or to be thin. The answer, it turns out, depends on which risk factors we consider.

Being fit means that you will have a lower A1C and a couple of other less widely known risk factors (the ankle-brachial index, which shows the severity of peripheral arterial disease or PAD, and the Framingham risk score, which measures your risk of having a heart attack in the next 10 years) than when you have a lower BMI.

On the other hand, a lower BMI was associated with a lower systolic blood pressure.

The conclusion seems inescapable to me. We have to be both fit and unfat if we are to avoid the most common severe complications of diabetes.

DAVID MENDOSA: “Curing Diabetes”

Monday, February 4th, 2008

“I was watching some doctors on TV recently where a couple of overweight people with diabetes had three months to see whether they could reduce their weight through good nutrition and exercise,” Gita in Australia emailed me this week. “These people achieved their goals and in describing the results, the doctors made the comment that, ‘They didn’t have diabetes any more.’”

Gita had thought that there is no cure for diabetes. So she searched the Internet and found other doctors who claim that they can reverse it.

Since Gita was still appropriately skeptical, she wrote me. I replied:

If a doctor thoroughly examined me today, he would find absolutely no evidence that I have diabetes (normal A1C, normal weight, normal cholesterol, normal blood pressure, no complications, no diabetes drugs). While it doesn’t look like I have diabetes, I act like I do, so it won’t return. I absolutely must adhere to the best principles of diabetes management to minimize the chances of recurrence.

There is no cure.

The most that I will claim for myself and for anyone who has his or her diabetes absolutely under control is that it is in remission. The word “reversing” is not precise enough for me.

If I had type 1 diabetes, all my efforts would not have put my diabetes into remission. That’s because, based on current understanding, type 1s have lost all their beta cells in their pancreas and nothing can replace them short of a transplant, which would require them to take dangerous immunosuppressive drugs for the rest of their lives.
But I have type 2 diabetes, which is by far more common than type 1. There are two problems with type 2, which is why I call it a “two-hit disease.”

Generally, the first problem that develops is insulin resistance in the cells of our bodies. So the pancreas must secrete more and more insulin in an attempt to get the insulin to transport glucose into the cells where we need it. Then, even before diabetes develops, these people — who we say have pre-diabetes or the metabolic syndrome — start to burn out their beta cells. They lose some of the beta cells in their pancreas, although not all of them (or essentially all of them) as type 1s do.

It is the insulin resistance that is reversible.

But we have absolutely no evidence in living people that any of the things that I did to put my diabetes into remission or those doctors did with the overweight people on the TV show that you saw will help to regenerate those dead beta cells. So people like me have to be extremely careful in our weight management and exercise lifestyle since we are essentially running on a gas tank that is nearly running out.

That said, there is some test tube evidence that we might be able to regenerate beta cells now or in the near future. This beta cell neogenesis might possibly be a huge side effect of taking the drug Byetta (and possibly some other drugs including insulin and Symlin), which I took for two years. It also looks like it might be occurring when tested in animals, but humans are a bit different from them.

This problem is the Heisenberg principle — that you can’t measure something without changing it. Most likely, the only way that we have to measure beta cell neogenesis is probably through an autopsy. For some personal reason, no one has volunteered.
