Diabetes Update: Medtronic Monitors

April 1, 2005

By David Mendosa


Boulder and the Flatirons

Boulder and the Flatirons

This newsletter keeps you up-to-date with new articles, Web pages, and books that I have written about diabetes.

  • I list and link most of these on my at Diabetes Directory and in the site’s menu.

  • From time to time Diabetes Update may also include links to other Web pages of special interest.

My recent contributions are:

  • Medtronic Monitors
    Medtronic Diabetes is not only the leading insulin pump company. It was also the first to offer a continuous monitor.

    While that monitor left a lot to be desired, the company has been moving steadily ahead on both the monitor and pump fronts. There are so many monitors in development that it gets confusing.

    The best of these monitors doesn’t even have a name yet. The company calls it the next generation Guardian Monitor. It should hit the market in a few years, in time for the current generation of blood glucose testers. The URL is Medtronic Monitors.

Scams:

More and more scammers write or call me so that I will tell you about the stuff they sell. I usually don’t write about them. This month, however, I have a couple of situations that I must bring to your attention.

  1. The first is for a diabetic neuropathy product that I have a lot of unanswered questions about. So I’m not ready yet to name the company. But the CEO of a reputable company does provide guidelines that you can use to do due diligence in making your buying decisions on this and other products:

    • Ask for their clinical data.
    • Ask how they arrived at their protocol.
    • Ask for a copy of their clearance by the Food and Drug Administration (FDA) or read it on the FDA’s website, http://www.fda.gov.
  2. The second is a contribution by an endocrinologist, Dr. William C. (Reddy) Biggs, who has a practice in Amarillo, Texas. Dr. Biggs is a frequent contributor to the most active diabetes newsgroups, misc.health.diabetes and alt.support.diabetes. With his permission here is one of his recent trenchant contributions:

    Every few weeks a spammer offers one of these discount medical cards in this forum. I can understand the potential appeal since diabetes makes purchasing health insurance difficult, if not impossible.

    It has been my experience that my office is often listed as a provider for these cards, even when it isn’t.

    An interesting study was posted on the web about these discount cards: http://www.cmwf.org/usr_doc/808_kofman_discountmedicalcards_ib.pdf

    It unfortunately confirms my impressions. They are often sold by high pressure salesmen, and may not live up to their claims. For four of five cards studied, the number of doctors accepting the card was a fraction of the number of providers listed.

    If you think one of these cards may work for you, be sure to confirm that your doctor’s office actually accepts them before you get pressured into signing up.

Research Notes: Salacia Oblonga

My correspondents stay up-to-date about new drugs and alternative therapies for diabetes. I wasn’t surprised to be asked about something called Salacia oblonga, also known as Celastraceae and Ponkoranti. This plant grows in India and Sri Lanka.

A short article in the January issue of the Journal of the American Dietetic Association entitled “Effects of a medical food containing an herbal alpha-glucosidase inhibitor on postprandial glycemia and insulinemia in healthy adults” triggered all of the interest. You can read the MEDLINE abstract online.

When you evaluate a proposed new treatment, you need to see what peer-reviewed research has been conducted. For that you need to search MEDLINE, the master index of all research reported in peer-reviewed journals since 1965. A search of “Salacia oblonga” turns up no more than10 studies, but only the one in the Journal of the American Dietetic Association was a study of humans. They previously studied its effects on rats.

Salacia oblonga is potentially an alternative treatment for diabetes. So, in addition, to checking out MEDLINE, when you want to check out alternative medicine, the only reliable source in my view is The Natural Pharmacist. You can find it several places online, including Memorial Hospital Jacksonville. But The Natural Pharmacist, which describes all herbs and supplements from Acetyl-L-Carnitine (ALC) to Zinc Sulfate, doesn’t even mention Salacia oblonga.

This one new study is really not enough to go on. Only 39 people were in the study, not enough to generally be considered as statistically significant. And the results seem strange:

Compared with the control, the 1,000-mg S oblonga extract dose reduced the plasma glucose and serum insulin incremental areas under the curve (0 to 120 minutes postprandial) by 23% (P=.32) and 29% (P=.01), respectively. The other doses of S oblonga extract [500 and 700mg] did not impact glycemia or insulinemia.

It is unusual and troublesome for a 1000 mg dose to have a big result and a 700 mg dose to have none. You have to consider this as very preliminary research.

Internet Resources:

The Internet has some great resources to help you evaluate medical treatments:

  • One that I have used, but never mentioned before is ConsumerLab. This thoroughly independent provider of products relating to health, wellness, and nutrition has some free research online and other results that you need to pay for. The URL is http://www.consumerlab.com

  • A complementary site is the Natural Pharmacist. In fact, you can read it on ConsumerLab.com, if you subscribe. However, I have often mentioned that you can also use it free online at Memorial Hospital Jacksonville

  • Another site will definitely cost you, but I use it all the time and can highly recommend it. iHerb.com is the best place I know of anywhere to buy vitamins, minerals, and supplements. It has the best prices, the largest selection, and the fastest shipping. The URL is http://www.iherb.com/

  • Another indispensable site is PubMed. This is a service of the U.S. National Library of Medicine and includes more than 15 million citations for biomedical articles back to the 1950’s. These citations are from MEDLINE and additional life science journals. PubMed includes links to many sites providing full text articles and other related resources. The URL is http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?

  • The U.S. government also has an authoritative site about food. The USDA National Nutrient Database must answer at least one question a week for me. The URL is http://www.nal.usda.gov/fnic/foodcomp/search/

  • If you are looking for a doctor, the best place to start is AMA Physician Select. This site, managed by the American Medical Association, provides basic professional information on virtually every licensed physician in the United States and its possessions, including more than 690,000 doctors of medicine (MD) and doctors of osteopathy or osteopathic medicine (DO). The URL is http://dbapps.ama-assn.org/aps/amahg.htm

  • Part of the American Diabetes Association’s huge website is “for health professionals and scientists.” That label doesn’t stop me, so I don’t see why it should stop you. The best part is the Clinical Practice Recommendations that appear in Diabetes Care every January. The URL is http://care.diabetesjournals.org/content/vol28/suppl_1/
Diabetes Television:

I have never been able to write about diabetes television before, because it didn’t exist until last month. The new show is called dLifeTV, and you can see this half-hour program weekly on the CNBC cable channel in your area on Sunday evenings.

I missed the premiere, because I had taped the wrong time. Some day I will master my VCR! [Just four days after sending out this newsletter a subscriber, William Beckerman, kindly sent me the DVD he had made for himself of the first episode. I don”t know how he did it, but the DVD was perfect, doing justice to an important program.] I saw all of the second program and was impressed by the frank coverage of a sensitive topic.

There are good people behind this program. Howard Steinberg, who has lived with type 1 diabetes for more than 36 years, started it. Even more familiar to most of us is Managing Editor Paula Ford-Martin, who for several years was the About.com diabetes guide.

Even the ads are worth watching. Most of them are about diabetes products.

Book Review:

    Johns Hopkins White Papers: Diabetes

    Johns Hopkins White Papers: Diabetes

  • Johns Hopkins White Papers: Diabetes
    This is a surprisingly good little book. Written by two professors of medicine at Johns Hopkins University School of Medicine in Baltimore, this “white paper” on diabetes clearly and authoritatively tells it like the current state of diabetes treatment is.

    It’s good (I mean the book is good, not necessarily the treatment of diabetes), but I am not saying to buy it. Most people with diabetes would be better advised to buy Gretchen Becker’s The First Year — Type 2 Diabetes or Dr. Alan L. Rubin’s Diabetes for Dummies. But this “white paper” is an excellent summary of the state of the endocrinological art.

    I was most impressed with this book’s review of recent journal articles that suggest that many more people with type 2 diabetes would be well advised to start using insulin earlier than they do. So many people have unwarranted concerns about insulin!

    The other part of this book that I was especially happy to see was a list of the top 10 hospitals for endocrinology. It is reprinted from an article in U.S. News & World Report on July 12, 2004, which I haven’t seen. The rankings are admittedly somewhat subjective, and are probably included because Johns Hopkins Hospital ranks so high.

    First is no surprise, the Mayo Clinic. Second, is Massachusetts General Hospital, which did surprise me. Then, came Johns Hopkins Hospital, which I know from my own experience back in 1976. I was in attendance to witness an abortion there in a previous life as a family planning officer for the U.S. Agency for International Development. Fourth, is the University of California, San Francisco, Medical Center, which probably was responsible for saving my wife’s life when she was there for a month in May 1998 for a complication of diabetes, blood clots. The other six are all around the country, but unfortunately there aren’t any in the top 10 near our new home in Colorado.

    This book is a part of the Johns Hopkins Health After 50 series. It’s 61 numbered pages (and a few unnumbered ones) published this year by Medletter Associates for $24.95. ISBN: 1-933087-05-6. The linked website is http://hopkinsafter50.com/html/silos/diabetes/index.php.

  • Excerpts “Fun with Diabetes” in the Style of Dr. Seuss

    Lancets! Test strips! Testing now!
    I can, you can, we know how.

    Look! See!
    Blood drops, one and two and three.
    Why won’t this meter beep for me?

    Numbers now. Number’s high!
    182 - my, oh my!

    Out with the insulin, out with the needle.
    Out with the afternoon snack-n-feedle.

    Up, up, up and down the stairs —
    Now I’m taking stairs in pairs.

    Down with the glucose readings!
    Down, down, down!
    I’ll have the best numbers in any town.

    Funny, now I cannot think —
    Think what I thunk and my heart begins to sink.

    Oops! Up with the sugar level — up, up, up!
    Glucose tablets, Gummi Drops, and sweetened juice in a big, BIG cup.

    But, see!
    High again, that’s where I am.
    Above 150, gosh darn damn.

    And on it goes throughout the day.
    Look, what fun! Come on and play.

    But like it? No, no, no, I say!
    I do not like the vials, the rules,
    the thinking, worrying all day…

    I do not like it one little bit.
    Still, I'm glad to LIVE with it.
