'IMAX Movie of Body' Allows Stanford Geneticist To Stop Diabetes In Its Tracks 137

sciencehabit writes "Michael Snyder has taken 'know thyself' to the next level. Over a 14-month period, the molecular geneticist analyzed his blood 20 different times to pluck out a wide variety of biochemical data depicting the status of his body's immune system, metabolism, and gene activity. In yesterday's issue of Cell (abstract), Snyder and a team of 40 other researchers present the results of this extraordinarily detailed look at his body, which they call an integrative personal omics profile (iPOP) because it combines cutting-edge scientific fields such as genomics (study of one's DNA), metabolomics (study of metabolism), and proteomics (study of proteins). Instead of seeing a snapshot of the body taken during the typical visit to a doctor's office, iPOP effectively offers an IMAX movie, which in Snyder's case had the added drama of charting his response to two viral infections and the emergence of type 2 diabetes."

    Let me know when they can stop, and reverse, Type 1.

    Type 1 is an autoimmune disease (or at least that's the most widely held belief) where the body's immune system attacks and destroys the insulin producing cells of the pancreas. As a result, the body stops production of insulin and without the administration of external insulin (primarily via injection), you die (quickly).

    To reverse the disease, two things are required. One, the body must be trained to not attack the the insulin producing cells. They've experimented with this for quite a while with anti-rejection drugs and similar things, and have had some moderate success. Once this is done, though, it's necessary to get the body to begin producing insulin again. There's some research that indicates the body may be capable of doing this spontaneously once step one is complete (at least in mice). Otherwise, an external source (transplant from a donor or cloning or stem cells or...) of these insulin producing cells will have to be added to the body.

    Cell is published by Elsevier which has been in the news recently because of a boycott. A search provides http://www.guardian.co.uk/science/2012/feb/02/academics-boycott-publisher-elsevier I support the boycott.

    It goes further than that, medical insurers will be required to spend 85% of revenues collected as premiums on the care of insured members [insuranceheadlines.com]. With a potential profit margin narrowed to 15% of revenue minus operating costs the US medical insurance industry will likely no longer be the darling of the investment community.

    Constant monitoring could be the next big thing in medicine.

    We currently diagnose based on discrete measurements compared with cutoffs - "averages" and numbers which are rounded to easily-remembered values. For example, Type-II diabetes is indicated when glucose is over 200mg/dl 2 hours after an oral glucose test. ...that seems like an awfully contrived number, simply because it's so easy to remember.

    Instead of single point cutoff measurements, maybe we could get better diagnoses if we could see the change in values over time. Perhaps a more accurate diagnosis of diabetes would come from characterizing the slope of several months worth of glucose measurements.

    With the rise of cheap microprocessors, I think there's a lot of opportunity for medical monitoring. Something like a wristwatch which records 10 types of measurements every hour. Of course I don't know how this could be done - perhaps spectroscopic measurements of reflected light through the skin, or terahertz wave reflections.

    I've often wondered if it's possible to make a USB peripheral that records to a TI Chronos wristwatch [electronicsweekly.com] for later display.

    I bet there's lots of interesting features there just waiting to be discovered.

    Type 1 is autoimmune diabetes, Type 2 is "everything else". That can be reduced insulin sensitivity, not producing enough insulin to support your body mass (which is why we equate fat=diabetic), and gestational diabetes where an increase in hormones prevents insulin from entering cells. The sources of the diseases are vastly different, but both result in increased blood sugar.

    The test to determine if you are type 1 or type 2 specifically looks for the immune system antibody (Islet of Langerhan antibody) in your blood stream. The part that is unknown is what 'triggers' a T1 diabetic to start producing this antibody. This most frequently happens when people are young, which gave it the name 'Juvenile Diabetes', but it's largely inaccurate. I was diagnosed at 27.

    Transplant patients routinely get Type 2 as a result of immunosupression. While it's primarily a lifestyle disease, it, like Type 1, can also be an immune disorder.

    From reading into this a bit (hadn't known of it)... post transplanet diabetes doesn't seem to be immune as much as the medications used for immunosuppression screwing up the bodies tolerances/handling.

    The immune system isn't causing it- the side effects of the meds are, basically.

    I'm sorry but carbs in general are not the enemy people make them out to be, nor is eliminating them from your diet a cure for type 2. There also are multiple factors that are linked as possible causes of type 2. In terms of type 2 caused by obesity (I have a family member dealing with this right now), the main goal is to increase exercise, improve diet and reduce weight. This does not require the elimination of carbs as a whole from the diet. Reducing or elimination of foods high in sugar content (especially soda) can greatly help, but there is no need to eliminate carbs sourced from grain. Additionally, there is the whole concept of thermodynamics in which consuming less than you use regardless of source will cause weight loss. Drinking soda is a good way to push your intake above your expenditure without even realizing it.

    1. I'm a type 2 Diabetic.
    2. I stand 6'1", and currently weigh 211 lbs. I have a 32" waist and can (and regularly do) bench press 295. I run 9 miles a week.
    3. Despite this, I still use pills to control my condition. I still have to have quarterly exams. including several hundred dollars in tests each time.
    4. I have better than average response to the meds, see fewer side effects than the average user, and unlike many diabetics, can get by on just a couple of generic drugs that don't cost me much. I have not had to change up to any of the more espensive drugs since I started. Less than a third of the type 2 diabetics under treatment can make that claim. .

    So on behalf of all the type 2's who have cut their weight, exercised, and stopped eating sugary foods but still have a serious medical condition, I'd like to offer a hearty "Fuck you, you ignorant idiot!" (I don't usually stoop to such language, but it's obvious that nothing less could possible get through to somebody like you). Really, you are spitting in the faces of thens or hundreds of thousands of people you never met, who have successfully fought a battle I doubt seriously you could win, and you are revealing you are unfamiliar with both the facts about a serious disease and fundamental human decency. I'm torn between being furious with you and pitying you.

    "eyelet transplantation" (ie, from a healthy donor, into a Type 1 Diabetes sufferer)

    For the sake of helping any searchers not miss a load of references through searching on "eyelets" ....

    These are "islets", not "eyelets", i.e. "Islets of Langerhans" (named for the scientist who first described them), they are little islands of special tissue in the pancreas gland, and they contain the beta-cells that normally make insulin, and in Type-1 diabetes they fail after attack by autoimmune processes. Their transplantation has been both promising and problematic, and as the parent post noted, tissue rejection problems have been met by immunosuppression.
