Tattoo To Monitor Diabetes 202
infonography notes that the "BBC is reporting about using tattoos to monitor the state of a diabetics' health. While TV's the Invisible Man series had this, this is actually real. Designed by Gerard Cote, of Texas A&M University they are made of polyethylene glycol beads that are coated with fluorescent molecules. Likely this will start to change the attitudes of parents who have been resisting the urging of their kids to get Tattoos."

My sister-in-law has passed out from low blood sugar several times in the last year. Before each episode, she said something akin to "Fuck off!".
Nowadays, when she says "Fuck off!" we force her to sit down and measure her blood sugar.
Of course, sometimes she has perfectly normal blood sugar, and has a perfectly legitimate reason to say "Fuck off!", and us saying "Are you feeling ok? Perhaps you should stick this sharp needle in your finger and experience some pain, just to alieve our fears" just makes her angrier...
But still, she completely passed out on me twice now, and each time we either had to force sugar into her convulsing, drooling mouth or stick a big needle into her quaking leg to counteract the effects of the insulin. It's scary...

You're in a high-risk group. Experience and simple economics have taught HMO's and doctors that monitoring high-risk patients more closely than low-risk patients pays off in the long run. Whether it "benefits" you is beside the point. If we wanted we could say that you are benefitted by being monitored more closely because of your higher risk factors, but from your perspective it might be preferable to go without monitoring and show up in the doctor's office only when you realize that something has gone wrong. But from the HMO and doctor's point of view, that is not a very cost-effective way of handling you.

And vCJD, worrying though it is (especially to people like me, who live and ate meat in the UK in the early 80s), is at least reasonably difficult to contract; we're not talking an ebola or influenza style pandemic here.

It sounds like there's a lot of details left to be worked out, but if something like this could serve as a continuous blood glucose diagnostic, I'm so there. Having been an insulin dependent diabetic for the last 13 years or so, a continuous blood glucose monitor has really been the most important missing piece to the whole puzzle.
Sampling my blood sugar once or twice a day is far too infrequent to get a sense of how my blood sugar rises and falls over time. Having a monitor that could record my blood sugar levels even every five minutes would be fantastic. Make it able to sample every five seconds and hook it up to an insulin pump, and you've got as close to a cybernetic cure as one could hope for.
Being an insulin-dependent diabetic is like driving a manual transmission car.. very workable, but you have to do a lot more work, and you have to know what the engine and gears are doing. If it's still too early for a cure, having a really good tachometer would be the next best thing.

Not pretty.
However, some massive new work is being done with encapsulating various forms of bio-active chemicals (the bleached ink molecules are enough to spawn an itch reaction) within various types of polymer chains. Some pretty interesting stuff is being done with encapuslating approaches...a really elegant breast cancer treatment works as follows: Take a potent anti-cancer agent (poison, to be blunt) and attach it to a non-toxic, heat-sensitive polymer, such that the combination of the two remains non-toxic.
Inject the combo into the bloodstream.
Take the patient, and dip her breasts in water hot enough to separate the polymer from the toxin. Now watch as two things happen:
1) Only the breasts reach critical temperature, so only they might be exposed to the chemo, and
2) The blood vessels in the breast will expand, and those sections with the most blood vessels will receive the highest dosage of the chemo. Those sections are usually tumors.
From what I can tell, it's pretty tricky to design the polymer that is stable at 98.6F and unstable at 105F -- any hotter, and you're doing damage with the heat alone! Creating arbitrarily stable non-toxics is comparitively much easier. That's what it sounds like they're doing here -- they're taking a molecule with a useful function (fluorescence), attaching it to something that prevents it from reaching toxicity, and linking the expression of fluorescence to the level of insulin surrounding the molecule.
It is likely a useful side effect of this will be generically functional fluorescent ink, replete with quite a bit more than the 20 pages of paperwork you're used to.

Now if we could combine continuous monitoring with an insulin delivery device, in such a way that the monitor controls the delivery, that would be pure heaven.
Imagine, insert an insulin and mabe a glucose cartridge every week or so, the monitor tells the device to deliver insulin when it detects a rise in glucose, and tells the device to deliver glucose when the glucose levels drop to hypoglycemic levels.
You could do anything you want, safe in the knowledge that your diabetes management device would keep your levels within not only safe, but healthy levels.
No more worrying if your late with dinner, or early with dinner - the glucose and insulin doses will even it out, want to go for a run, just go - the glucose will make up the shortfall if needed, want to veg out on the couch, by all means - the device wil just supply a little more insulin to cover your lazyness. It'd be like having a superislet (islet's are the cells that produce insulin for you non-diabetics).
I think the delivery is the easy bit, you could just strap a small device with a needle to your arm or something. The monitoring is the difficult bit, from what I know of the current continuous monitors they are neither accurate or infact particularly continuous.

The relative benefits of various types of exercise would be more readily apparent, and immediate feedback would encourage more healthy lifestyles.
There is already ample evidence that one of the major keys to a long and healthy life is the reduction of the amount of insulin your body needs (others include wearing seat belts, avoiding violent crime, getting ample sleep, avoiding environmental poisons, not taking gratuitous risks, not smoking, etc.).
One can only hope that some better way of doing this can be found. Since current bg monitoring is done by IR absorption/transmission, I would think that a small IR reflector could be implanted, perhaps just under an artery or vein in the arm near the skin's surface. Then a monitor could use this to directly read bg (perhaps with occasional calibration with other methods) using a short IR burst.
Other things I'd like to be able to measure (inexpensively) in real time: Insulin level, HD/LD/TG, ghrelin (and its recently-discovered agonist, which doesn't have a popular name yet), white cell count, seritonin, and DHEAS.
