How Doctors Die
If we compile statistics, we can look for the points where nobody has ever meaningfully recovered.
We do. This is where the guidance to stop resuscitation after 15 minutes without a rhythm comes in. Unless you're a child who drowned in cold fresh water, of course, or an adult who apparently died of hypothermia. The problem is that there are so very many different sets of facts, and people are far more resilient than you can imagine. And in the heat of the moment, we tend to opt to fight rather than to let go. Which is actually OK, I think.
For your example, ECMO can only be useful for acute lung failures including injury. It's useless in chronic cases where the lungs simply aren't going to improve.
Well, yes, ECMO is probably a bad example, because it's by definition an acute therapy that can't be continued more than a few days, at least at the current state of the art. Even there it's a bit questionable in the case of chronic disease exacerbated by acute cardiopulmonary collapse from a (presumably) reversible cause. But other therapies, like the simple $10K/day ICU bed, are much harder to argue against, unless you've given specific instructions. It reminds me a little of the old instructions for tuning a carburetor - turn the screw until the engine dies, then back up half a turn. Most of the really futile ICU cases I've seen didn't START as futile cases, but they sure ended that way.
Most other western countries have a bit less tendency to heroic medicine than the U.S.
I'm not actually all that impressed with medicine in "most other Western countries" as a touchstone for our own. Every country has its own social norms and conventions, all of which fold over into health care. We tend to value privacy, autonomy, personal space, personal choice, and hope for recovery more than most, and it costs us a lot of money.
How Doctors Die
I think the problem is that we don't know in advance when the "last days of life" are for anyone. Or at least we don't know if prospectively, and knowing it after the fact is kind of pointless in terms of limiting costs.
If there are treatments that are virtually never helpful, we need to stop using them. There aren't many interventions that actually fit that description, though, and even the most invasive of them - ECMO, for example (basically continuous heart-lung bypass) - have their place in restoring people to health in the right circumstances. Eventually the circumstances are such that death is inevitable, but recognizing that point is not something we know how to do with certainty. Even when we're pretty sure, communicating our own conviction is very hard. And where there is no certainty, there is the great likelihood of erring on the side of treatment.
Hospice care, which tends to be very inexpensive compared to attempts at cure, is helping because it gives people a viable alternative path. Most physicians with whom I deal (a very large number, as it turns out) are big fans of hospice care. Not because it's cheap, but because it helps make the case for avoiding further torture. It's not a bad way to reduce costs, though, and that's not irrelevant.
How Doctors Die
I'm a board-certified physician (among other things). There is no way that I would allow my colleagues to inflict the kind of death on me that they are forced to inflict on so many. Part of this is certainly that I know full well that we all exit this mortal coil toes-up, and there's no getting around it. Part of this is the personal reluctance to experience the diminished autonomy, indignity, pain,and hopelessness that comes with fanatically-treated terminal illness.
But a big part of it, I think, is just that I know that there are so, so many things that are worse than simply dying. Dying in agony, for one. Dying after having bankrupted my wife or my children. Dying after being reduced to a stinking thing in a bed long enough that only those who loved me most even want to be near me, and that only because they feel they must. Physicians see these things all the time, and we see the road that leads to them. We're not (that) stupid, and we would rather exit early on that road, not at its terminus.
As long as I have the capacity for joy I will strive to remain alive to experience that joy. When the capacity - or the joy - is gone for good, I have given quite strict instructions not only to my family but to some other clear-headed and insistent people who will do their best to ensure that I too will be gone without further "heroic" intervention.
The only problem that I have with the article is that it pretends that everyone should make the same decisions. Everyone has their own decisions to make, and without my knowledge and experience I might not make the same ones. I think as physicians we owe it to the people for whom we care to educate as well as we can and help them to understand why we might personally decide one way or another. But I will never tell them how they "ought" to decide - it's really their choice. Taking that choice away from a person leads too easily to very real outcomes that are much nastier than simply a life that ends later than it ought.
Judge orders IP logs released to Sony from PS3...
Not that I was all that fond of Sony anyway. Trying to rootkit my machine from a CD a few years ago didn't impress me, and the prices they charge have always been a little silly. With this action, Sony has now officially asked their lawyers to burn down decades of customer relationships. "Sony" and "Don't buy this" are now synonymous.
As far as two years of IP logs, good luck with getting anything useful out of that one. Then again, that wasn't the point. It was just another intimidation tactic to keep people from spreading the private keys. A little late, I think.
Startup Tests Drugs Aimed at Autism
The article is pretty good, actually, in that it doesn't try very hard to claim that they're curing the world of its ills. There's a little in there, but mostly it deals with Fragile X.
Randi Hagerman (the researcher quoted extensively in the article) is one of the leading lights in Fragile X research. She and her husband, Paul, described the gene, developed the RFLP that we now use to diagnose the illness, and did much of the fundamental work to explain the genetic-expression behavior of the gene. It is not a simple inheritance model, and the expression of the gene is quite confusing. She's a superstar.
As far as the broader issue of autism (and even more confusingly, autism spectrum), Fragile X has always seemed to me to be a blind alley. People with Fragile X (I've worked in that community as a physician) have a very specific affect and behavior pattern that doesn't look a lot like the behavior of people with autism (a community I know all too well as a physician and a parent of an autistic young man). Most of the early research in autism was tainted by the inclusion of Fragile X patients, and most of the combined research is just confusing.
I hope that the drug proves useful in Fragile X, although pharmacotherapy for these kinds of disorders has frustrated us over and over again. These are simply very hard diseases to affect very much. At the least, though, it'll be another step toward understanding a serious disease. And I'll continue to wait and watch for anything that will help in autism, but I REALLY don't expect much from this specific drug.
The Best Medications For Your Genes
The FDA has had a table of valid genetic biomarkers for medications for several years now. While many of these are cancer drugs looking at specific metatabolic or receptor issues, our old friend warfarin (a "blood thinner" with a narrow therapeutic index, a reputation for causing a lot of trouble and a genomic profile that accounts for about half of the known variation in the drug) and the pain drug codeine are on that list as well. There's even a research website devoted to genetic calculation of warfarin dosing.
Carbamazepine (Tegretol) can cause a rare life-threatening reaction called Stevens-Johnson Syndrome (Toxic Epidermal Necrolysis), but it's mostly limited to individuals with a specific Human Leukocyte Antigen (HLA-B*1502). Again, known for quite a while and a part of the basic biology of the drug.
It's a fairly well-written article, but it's kind of breathless about stuff that I was really excited about back in the '90's when my medical school teachers were really excited about it too. The best news is that the FDA has really stepped up in the past few years to make this actionable data that a practicing clinician can use.
Alzheimer's Disease Possibly Linked To Sleep Deprivation
Okay, so let's give credit - this is a legitimate researcher doing interesting (if highly preliminary) work. From his bio, accessible from TFA, you find that:
We have been assessing CSF and plasma samples from human subjects at the Washington University ADRC and have found that decreased CSF [alpha-beta] and increased tau are harbingers of cognitive decline in cognitively normal elderly.
Which suggests that the increase in CSF beta protein seen in sleep deprivation might actually be a harbinger of protection from Alzheimer Disease (AD). Or not, and it's not possible to know right now. Your speculation is just as valid as mine.
The problem is that we don't know if the protein causes the neuronal damage in AD or is a side effect of the damage, like a clot or a scar. Dr. Holzman's research bio makes that clear, and it also makes it clear that the damage, whatever it is, starts decades before the protein levels become abnormal. So if you want to avoid sleep deprivation, that's cool, and the fact that most people reading this site are hopelessly sleep deprived most of the time is probably cool too. Either way, our other lifestyle issues will likely collect us long before our brains start to rot.
On the plus side, we now know how to make mice demented. It's not much, but it's something.
HIV/AIDS Vaccine To Begin Phase I Human Trials
Amen. The vaccine has showed animal immunogenicity, which is not a bad thing, but since the animals in question don't get AIDS from HIV, their immune systems don't react the same way that human ones do. Which means you need to proceed to human testing, and that takes a long time.
Phase I trials are important, and announcing them is not a bad thing. And nobody particularly expects cures in the HIV-positive population, although circulating HIV may be interesting (if the virus can cause a practical immune response in subjects with HIV but who have fairly normal T4 counts and you can show reduced circulating viral load, you have an interesting data point for efficacy).
My biggest problem with this kind of press release is that they don't include the details. I'd be interested in knowing why this vaccine is likely to work better than the last two hundred that have been tried, what the actual animal studies showed, and so on. Oh well. I'm not going to be waiting up this weekend to hear more. It will be a couple of years before we know whether this one works.
HIV/AIDS Vaccine To Begin Phase I Human Trials
Unfortunately (OK, it's not unfortunate at all, actually), option #1 isn't just taboo, it's impossible in any human society. Even if we had a completely accurate test (which we certainly do NOT have), and even if you could somehow prevent all positive contacts from continuing their infectious behavior (and I'm not sure anything short of summary execution would be reliable), you'd still have leakers, avoiders, corruption, and resistance. Not even North Korea has managed to avoid HIV, although they're close, at least by report. Largely, I suspect, because summary execution is a routine thing for them.
Option #2 is science fiction for now. The genetic resistance to HIV is conferred by the lack of a particular cell-surface receptor, so you'd have to find a way to effectively eliminate that piece of genetic material from every genome in the body. And since T cells are quite long-lived, you'd have to mess with a lot of quiescent DNA to do it. Maybe some day, but not soon.
Which leaves vaccination. I'm in agreement with your skepticism on this one, not because it's impossible but because HIV, due to its unique targeting system, has been very intractable. You do have to target relatively stable regions of its proteins or its DNA, but this isn't unique to HIV, and we've solved it with polyvalent vaccines elsewhere (think Menactra, or the recent HPV vaccine, or even the flu shot). HIV is a pretty wimpy virus from a spread perspective, so a good polyvalent vaccine would seem possible. The problem is practical immunogenicity, and that's the issue that has torpedoed previous vaccines.
Resisting the PGP Whole Disk Encryption Craze
Fine, as long as you work my hours. I work in a job where I may be setting up at 0500 for a multi-person network-heavy presentation scheduled to go at 0630, and I have zero time for argument. I've had great support and lousy support, and yes, I bring my own network hardware in case the local admin doesn't have what I need.
That said, I almost never have a problem, because good network admins do indeed work with me, and lousy ones either (a) aren't there to complain, or (b) trust me far more than they should. Oh, and I ask (and explain and discuss and compromise) long before any equipment sees power. It's only polite.
I've never (ten years or so) had a local hardware issue extend into the host network. It seems to be fairly hard to do that if you're not an idiot (and if your own equipment is truly solid, which mine is).
