Brain Surgery Can Now Be Conducted Through the Eye Socket

Eyeball Syringe

Surgeons at the University of California, San Diego, School of Medicine and University of Washington Medical Center have determined that transorbital neuroendoscopic surgery (TONES) is a safe and effective option for treating a variety of advanced brain diseases and traumatic injuries. This groundbreaking minimally invasive surgery is performed through the eye socket, thus eliminating the removal of the top of the skull to access the brain. These findings were published in the September issue of Neurosurgery

Right or Left Handed? Transcranial Magnetic Stimulation Can Shift Your Preference

Transcranial Magnetic Stimulation (TMS)

When performing simple tasks like pushing elevator buttons or picking up a cup, the brain actually has a mini-debate as to which hand should do the jobs. Now magnetic stimulation will make sure the brain always chooses the left hand.

Researchers found they could influence the decision about what hand to use in simple tasks using transcranial magnetic stimulation (TMS). The finding could have medical applications in assisting patients who have lost or damaged limbs. It may also suggest the possibility to manipulate other decisions using TMS.

Study Finds Relationships Help You Live Longer

No man is an island, and if he tries to be one, he may die sooner, according to a new BYU analysis.

Researchers have discovered that people with greater social relationships are 50 percent more likely to live longer than their socially reclusive counterparts.

In fact, a lack of friends is as damaging as smoking 15 cigarettes a day or being an alcoholic. It’s also twice as damaging as obesity and more harmful than not exercising, according to the study.

“We’re not in any way trying to downplay the seriousness of these other risk factors, (which) are very important,” said author Julianne Holt-Lunstad, associate professor of psychology at BYU. “Rather, we’re trying to make the point that we need to start taking our social relationships just as seriously as we take these other factors.”

The researchers combed through thousands of studies since 1900 to find 148 that dealt with their research questions. Those studies asked more than 300,000 subjects about relationships and then tracked their health outcomes for an average of 7.5 years.

Stem Cells From Human Blood Can Be Reprogrammed

blood donation

Blood drawn with a simple needle stick can be coaxed into producing stem cells that may have the ability to form any type of tissue in the body, three independent papers report in the July 2 Cell Stem Cell. The new technique will allow scientists to tap a large, readily available source of personalized stem cells.

Because taking blood is safe, fast and efficient compared to current stem cell harvesting methods, some of which include biopsies and pretreatments with drugs, researchers hope that blood-derived stem cells could one day be used to study and treat diseases — though major safety hurdles remain.

The Rise Of ‘Transplant Tourism’ – Should Organ Sales be Legalized?

polycystic kidney

How much is your kidney worth?

In Turkey the prized organ fetches around €2,300, an Indian or Iraqi kidney enriches its former owner by a mere €800, and the World Health Organisation (WHO) estimates the going price on the black market to be about €4,000.

But when you consider that wealthy clients will later pay well over €100,000 for the kidney, this massive profit margin would appear to guarantee a lucrative future for the international trade in human organs if it continues unchecked.

Suspended-animation cold sleep achieved in lab

suspended animation

Dr. Mark Roth’s team at the Fred Hutchinson Cancer Research Center has figured out how to freeze and re-animate worms and yeasts. The trick is that they must be oxygen deprived before freezing. Knowing that there’s been a few well known cases of humans being frozen and revived, they’re hoping they can extend this technique to humans.

The idea here is not so much to place people into deep freeze in order to endure lengthy interstellar voyages, a staple idea in science fiction but unlikely in the near future (humanity is struggling even to assemble a Mars mission right now).

Rather, Roth and his colleagues think that their work might lead to techniques that would let paramedics or doctors “buy time” for severely injured or ill patients by putting them into suspended states like those achieved by Nordby and Uchikoshi. Then, once the underlying problem had been fixed, they could be reanimated.

Disrupting Bacterial Communications Could Compliment Antibiotics

Chatter between bacterial cells may stall healing of skin wounds, and sabotaging that chitchat could offer another way to battle infection, new research suggests.

Making Pseudomonas aeruginosa deaf to the molecular signals that the bacteria use to talk to each other would offer a kind of antibiotic therapy that doesn’t kill bacterial cells but rather strikes at their ability to attack human cells en masse, Jasper Jacobsen of the Statens Serum Institute in Copenhagen said May 24 at a meeting of the American Society for Microbiology.

Mechanism Points to Acupuncture Pain Relief

Acupuncture

Scientists tried the technique on mice that had a pain in the paw, inserting and rotating the needles in the mouse version of one of the most effective acupoints in Chinese medicine. And they found that the tissues around the treated acupoint get flooded with adenosine, a chemical that provides relief by preventing pain signals from reaching the brain.

This biochemical blockade reduced the animals’ discomfort, as did treating them with drugs that boost the amount of adenosine in the tissue. The scientists say the pain relief stems from the body’s natural response to minor tissue injury.

Participatory medicine with Jon Lebkowsky – Technoccult interview

Jon Lebkowsky

Jon Lebkowsky is a social media consultant and cofounder of the Society for Participatory Medicine. He was also the co-founder of FringeWare, Inc. and EFF-Austin, co-edited Extreme Democracy, and is a regular contributor to WorldChanging. You can read his blog here and follow him on Twitter here.

Klint Finley: Let’s start off by defining what “participatory medicine” is.

Jon Lebkowsky: There’s a good definition on Wikipedia:

Participatory Medicine is a model of medical care in which the active role of the patient is emphasized.” It can be patients coming together in communities dedicated to a specific disease or condition, or it can be patients being considered peers within treatment teams that are treating their conditions.

The Internet makes it more possible, in that patients can find much more information about their conditions online, and they can find each other.

You’ve been involved with online communities for many years, how did you get involved with participator medicine?

Through my relationship with Tom Ferguson. Tom was a participatory medicine pioneer. He had edited the health section of the Whole Earth Catalogs, and published a magazine called Medical Self Care. We started talking and hanging out in the early 90s – he found me via EFF-Austin. He could see the potential for the Internet to provide patients access to more and more information, and he had always advocated for patients to be as informed as possible, and to have a role in treatment… and do as much for themselves as possible.

He had a grant from the Robert Wood Johnson Foundation to do a white paper on e-patients (See e-patients.net), and he knew that blogs and social technology would be relevant. He wanted me to join his team of physicians and others because I was involved in the evolution of social technology, what some now call social media.

I started working with the e-patients working group and became a founding member of the Society of Participatory Medicine.

How long this movement had been afoot? I’ve read that things like this were going on as far back as the 80s in places like the WELL.

Yes, there’ve been a lot of patient conversations and communities over the years in various contexts. The WELL has always had an active health conference, and patient communities like ACOR have been around for a while.

Other than there being a lot more people involved now that the Internet has become mainstream, is there any big difference between what’s going on now and what was going on way back when?

In a way, yes. With higher adoption of the Internet, you have so many more patients getting active online. And the tools are evolving so that it’s easier to create contexts for conversation. Also, partly thru Tom’s work and the Society, and other orgs like PatientsLikeMe and the Health 2.0 conference, you have a lot more interest, activity, and potential for innovation. And there’s more information coming online, so patients can theoretically be better informed. There’s also new tools for people to manage their health records online, and track aspects of their health. More hospitals and healthcare professionals are starting to use social media to connect with patients and for community engagement.
We have a whole movement forming around patient demands for access to their complete health records.

Can you give any examples of “success stories” in participatory medicine – anything that really stands out? Like a situation where you could say “Wow, that recovery could never have happened otherwise.”

Dave deBronkart. He had 4th stage terminal cancer, is now in remission. If he hadn’t been an e-patient, he might never have found the treatment that made him so much better.

Here’s what the Wikipedia article about him says:

His kidney was removed laparoscopically and he was treated in a clinical trial of high-dose interleukin-2 (HDIL-2), ending 7/23/07, which was effective in reducing the cancer, although his femur ultimately broke from damage caused by the disease. Visible lesions on follow-up CT scans continued to shrink for a year and have been stable since, and are presumed dead.

He learned of the treatment through his e-patient activiites and research. No one had told him about it. If a healthcare provider can’t offer a treatment, they don’t necessarily know about it or tell you about it.

Is there a downside? Increased “cyberchondria,” or decreased trust in physicians?

Jon L. Part of the power of participatory medicine is in patients collaboratively researching and discussing various treatments. More powerful than a single source of information. There’s a potential down side – a physician has a different context for assessing information, and may make different judgements. But it’s good for patients to be more informed. For the physician, there can be an issue of having to spend more time with patients explaining why something they’ve found online might be inaccurate or inapplicable.

Physicians who believe patients should be empowered can be pretty good about that, though.

And there are physicians who don’t assume they necessarily have the answers, and are very willing to listen to patients who’ve been researching, and consider what they have to say.

The patient has a strong vested interest in outcomes, and will sometimes dig more deeply and thoroughly than the healthcare professional has time to do.

Here’s another downside to consider: some patients may become more knowledgeable about their conditions than their doctors. There’s a tendency for people, and I’m as guilty of it as anyone, to sort of double-down on their position if their expertise is questioned- especially if that expertise is questioned by an amateur. A physician might not want to admit they were wrong about something and their patient, who might not have ever even been to college, was right.

Yes, that’s definitely a concern. The solution is to create a culture where patients can be seen as peers. (Though not all patients will want that… many will.)

Not to be too personal, but have you been an e-patient yourself?

Jon L. Yes, but not with anything life-threatening, at least no so far. I have psoriasis and have researched it online, and was on a psoriasis email list for a while. I left it. My general sense was that the list was dominated by people who had strong feelings about what would or wouldn’t work – e.g. would vehemently oppose other patients who felt there was a potential to see results through changes in nutrition. I had a feeling they were being defensive – didn’t want to change their eating habits. So not all communities will be functional, or will work for all members.

I also had a problem with arrhythmia that seems to have been treated effectively by cardioversion and a round of drugs. I researched the drugs and decided I felt they were too toxic to continue, so I stopped after a year and a half. The cardio would have preferred I continued at least another six months.

Do you have any recommendations for potential e-patients for finding resources and communities, or places to avoid?

I would counsel proceeding with caution until you’ve felt your way into it, and got a good sense of the online landscape for your condition. It’s so easy to be misled, to get the wrong info. There are some communities that are well-established, and are the best places to go for specific conditions – like ACOR for cancer.

Also in researching your condition, remember that you’re not a physician or health researcher, so you don’t have the same context for assessing the information you find. Don’t assume your physician is wrong if you find contradictory information online.

You can get a sense of the landscape by reading e-patients.net and Journal of Participatory Medicine (the latter is the journal that the Society for Participatory Medicine started). There are also a lot of bloggers and tweeters in the e-patient space. Here’s a blogger on patient advocacy: Every Patient’s Advocate

Ed Bennett has resources for healthcare professionals.

Is there anything of note in the recent health care overhaul regarding participatory medicine?

It’s more of an insurance overhaul than a healthcare overhaul. I don’t think it has a lot of impact on what we’re talking about.

One thing specifically mentioned on the Society for Participatory Medicine’s web site is a need to address the digital divide’s impact on participatory medicine. Do you know of anything being done, or do have any ideas for solutions?

I don’t think there’s a specific project to address digital divide in this context. In fact, the community network / digital divide efforts in general seem to lack steam. Part of that is because Internet adoption is so high, it seemed that the issue was resolving as we had more and more ways for people to get online, and more incentives for them to do so. However I know there’s a significant number of adults who don’t have the kind of access they should, especially considering that so infrastructure for services is moving online.

State and smaller governments, for instance, are moving services online for the efficiency.

It’s not just a matter of access either, there’s also a matter of online literacy.

And when we get to the point where all healthcare data for everyone is available digitally, not just as an electronic health record but as a personal health record, only those who have the right degree of digital literacy will be able to have that as a factor in managing their health. To me the digital divide is more about knowing how to use computers than actually owning the hardware, so I’m with you 100%.

Bruce Sterling, in the State of the World conversation you moderated, suggested the possibility that individuals, informed by various web based instructional materials, could start doing amateur medical operations. It was clear that what he was talking about wasn’t what you were talking about in terms of participatory medicine at the time, but have you thought anymore about that scenario?

I think it’s pretty unlikely – he was seeing that as the ad absurdum where participatory medicine could go, but I think that’s a real misunderstanding (and I don’t think he seriously believed it would go there). That’s really not what “participatory medicine” and “empowered patient” is about… when we talk about being better informed and being part of the conversation about your own health, it doesn’t follow that anyone would necessarily want to be an amateur surgeon.

Maybe not in the global North, but I can imagine it happening elsewhere, where access to professional health care is worse. Or even here in the States if economic conditions worsen.

You have a point there, but it’s not really what participatory medicine is about.

I could imagine someone learning how to do just one or two particular procedures really well and just doing doing those.

We are near a point where only the elite can afford adequate care. Yes, very possible.

Right, so the “participatory” in participatory medicine means more participating in the decisions, not doing surgeries.

Right… participating in the knowledge, and in the decisions.

Well, I think that about wraps it up. Do you have any closing thoughts?

My focus has always been on the Internet and its impact on culture, so participatory medicine is just one of a set of related interests. I’m still thinking about what’s really happening and how what’s happening in various sectors relate – participatory medicine to the changes in journalism and in politics, for instance.

A Healthy Lifestyle May Not Affect Your Longevity

Centenarians

SCIENTISTS have discovered the “Methuselah” genes whose lucky carriers have a much improved chance of living to 100 even if they indulge in an unhealthy lifestyle.

The genes appear to protect people against the effects of smoking and bad diet and can also delay the onset of age-related illnesses such as cancer and heart disease by up to three decades.

No single gene is a guaranteed fountain of youth. Instead, the secret of longevity probably lies in having the right “suite” of genes, according to new studies of centenarians and their families. Such combinations are extremely rare — only one person in 10,000 reaches the age of 100.

Found: genes that let you live to 100

Also, an active social life beyond one’s own family contributes to one’s longevity, happiness, and intelligence in later life.
