Octuplets- An Abdication of Medical & Parental Responsibility

In concept I am a big believer in giving people freedom to live their lives and do what they are going to do with the caveat that the limits are drawn when their actions hurt others. Nadya Suleman and the doctor who helped her have crossed the line.

They have abdicated moral and parental responsibility with little to no regard for the impact of their actions. Their actions are selfish and misguided and it infuriates me that the public is going to be forced to help support the moronic decisions made by all of the parties here.

The LA Times has a number of articles that document the sad state of affairs of a mother who has 14 children, no source of income and owes $50,000 in student loans. Oh and did I mention that she is already receiving money from food stamps and that three of her children are disabled.

This makes me want to tear my hair out. This article outlines a number of serious issues and her complete lack of touch with reality. I believe in social responsibility. I believe that we have an obligation to try and give people a hand up, not a hand out. But apparently she feels otherwise. We’ll get to that in a moment.

“Even before she gave birth to the octuplets Jan. 26, Suleman was receiving $490 in monthly food stamps, and three of her children were receiving federal supplemental security income because they are disabled.

Let’s review because it really does blow me away. She is an unemployed single mother of six children who is receiving almost $500 a month in food stamps and additional money from the federal government for the disabled children goes t o a doctor and undergoes IVF and then delivers eight more children.

Eight more children. Eight more children who will be in the hospital somewhere between seven to twelve weeks. According to the Times that bill will run on the low end at about $500k and could approach more than $800k, provided that there aren’t any complications.

And that doesn’t take into account the team of more than 46 medical professionals who were assembled for the delivery. But none of this matters to Suleman. She engages in some sort of mental masturbation that allows her to try and say that she is not really receiving any sort of assistance.

“I’m not living off any taxpayer money,” she said. “If I am, if it’s food stamps, it’s a temporary resource. And I was so reluctant. I very much so look forward to the day when I am not getting any kind of help with food stamps, which I believe will end when I graduate in about a year or year and a half.”

Oh ok, you’re going to collect somewhere around nine grand in food stamps, not to mention however much you receive for the disabled children. And during that time what sort of activities will you be engaged in. Are we to believe that you are going to work so that you can support your children and so that you might pay into the system. Doesn’t sound like it.

Some people might say that I am being too harsh, but this was elective. She didn’t have to have more children. She had six and don’t forget that some are disabled. Six healthy children are a lot of work, but when some of them are disabled there is more to be done. And now she has increased the load ten fold.

But we shouldn’t worry because in lollipop land everything works out.

Suleman also bristled at suggestions made by some commentators that she was being irresponsible for having so many children with no income or partner to help raise them.”No. I am not being selfish. . . . If I were just sitting down watching TV and not being as determined as I am to succeed and provide a better future for my children, I believe that would be considered to a certain degree selfish,” she said.

Great. She is determined to succeed and by gum that makes all the difference. I believe in having a “can do” attitude and that it makes a difference, but again there are limits. She doesn’t have the financial resources to take care of these children there are legitimate questions about whether she’ll have the time. Fourteen young children, eight of whom are infants. It is just wrong.

But never fear, she has a website that she is using to ask for donations.

And lest we think that I have forgotten about the doctor and clinic let’s shed some light on these mental midgets.

According to records reviewed by the Times

The Beverly Hills doctor whose fertility treatment led to the birth of Nadya Suleman’s octuplets – and her six previous children – has one of the worst success rates of any fertility clinic in the country, according to federal records reviewed by The Times.

In fact, Suleman’s children represent a sizable portion of the pregnancy rate at his clinic over the last several years

The Times used data from 2006. Out of 61 procedures only five resulted in pregnancies and only two of those resulted in births. So we have a mother whose completely out of touch with reality and a doctor who is seemingly inept with everyone but her.

Even better the good doctor has been involved in a number of lawsuits with past employees.

It is a perfect storm of chaos and we’re the lucky people who get to pick up the pieces. Just peachy.

Is That A Camera In Your Eye

Talk about playing Eye Spy. Wired has the story of a man who intends to place a miniature camera in his eyesocket. Don’t worry, he isn’t going to remove a live eye to do this. Apparently he had one removed a number of years ago. You can even see a short video of the surgery he had to extract it.

Click here for the full story or just settle for the excerpt I am going to post.

“When you completely lose an eye it is a difficult thing to let go of,” he says. “The eye has an emotional attachment. It is a window to your soul.”

Spence wore an eye patch for a while, which he says looked cool. But once he started thinking about having a camera in his eye, Spence got in touch with Steve Mann, a professor at the University of Toronto. Mann is one of the experts in the world of wearable computing and cyborgs — organisms that blend natural and artificial systems.

“There are a lot of challenges in this,” says Mann, “from actually building a camera system that works, to sending and receiving images, to getting the correct shape of the camera.”
Even in the age of miniaturization, getting a wireless video camera into a prosthetic eye isn’t easy. The shape of the prosthetic is the biggest limitation: In Spence’s case, it’s 9-mm thick, 30-mm long and 28-mm high.

While that might seem like plenty of room in an age when digital cameras are squeezed into unimaginably slim and compact phones, it actually isn’t. The average area available inside a prosthetic eye for an imaging sensor is only about 8 square mm, explains Phil Bowen, an ocularist who is working with Spence. Also, a digital camera has many more components than the visible lens and the sensor behind it, including the power supply and image-processing circuitry. Getting a completely self-contained camera module to fit into the tiny hollow of a prosthetic eye is a significant engineering challenge.

That’s where Professors Huang and Rogers’ research could come in handy. Three months ago, the duo published a paper that showed how a new sensor built out of a flexible mesh of wire-connected pixels could replace the traditional flat imaging chip as the light sensor for a camera. The mesh is made from many of the same materials as a standard digital-camera sensor, but it has the ability to conform to convoluted, irregular surfaces — like the back of a synthetic eyeball.
“Our cameras might more naturally integrate with a prosthetic eye, due to their hemispherical shapes,” says Rogers. “One might also argue that they can provide a more human-like perception of the world.”

Then there’s the question of how the prosthetic eyeball (the outer shell for the camera) will be made. The eyeball chassis has to close shut and be watertight.

Traditional prosthetic eyes are single pieces made with polymethyl-methacrylate (PMMA), a flexible polymer that is also used in dentures. To fit a camera in, Bowen redesigned the prosthetic eye into two pieces that could snap shut.

But with a camera inside there’s something new to worry about. The modified prosthetic eye will be heavier than traditional ones and that could affect the eye socket, says Bowen. “The weight might stretch out the lower lid,” he says, potentially disfiguring the face.

The Science of Lines

I thought that this article about the study of queuing was interesting. Especially as it sometimes feels like I spend my life waiting in lines for one thing or another. And in case you are wondering, the answer is that you stand in line, not on line.

If you read the whole article you’ll see that they found that knowing how long you are going to wait reduces anxiety. Duh. I could have predicted that. But it still doesn’t solve the problems you sometimes encounter when stuck behind the man/woman who screams into their cellphone or whose unpleasant scent makes you want to gag.

You may not know it, but the seemingly mundane task of forming a queue at the airport, a fast-food joint or a post-Thanksgiving midnight sale is the subject of careful study by experts in the field of queuing psychology.

The findings may not always reduce wait times, but they can cut frustration and make people feel better, or even happy, about waiting in line, said Richard Larson, who has researched queuing psychology for more than two decades.

“You can change a queuing experience into a very positive experience,” said Larson, director of the Center for Engineering Systems Fundamentals at the Massachusetts Institute of Technology.

To do that, businesses where people often wait in line must realize some basic principles of queuing psychology.

Eliminating empty time, for example, makes waits seem shorter, Larson found in his research.
Visitors lining up for attractions at theme parks see this principle at work with queues that often use clever design and technology to make the line itself entertaining.

“We like to view [queues] as the first scene in the story, whatever the story of that particular attraction is,” said Joe Garlington, creative vice president of interactives at Walt Disney Imagineering, which develops Disney parks and resorts.

The line to one popular attraction at Epcot features cameras and large interactive screens that allow visitors to see themselves and play games, such as trying to burst virtual water balloons to reveal a hidden image, Garlington said.

People waiting in line for a comedy show at Walt Disney World are asked to text message jokes that may be used during the main event.

“It works as our warm-up act essentially for the show, but it also takes time while people are working through that and so it keeps them entertained while they’re waiting,” Garlington said.

“We do study the psychology, try to understand what our guests are thinking and make sure that we’re keeping them happy as they move through the lines.”

Disney employs more than 75 industrial engineers who help the company with queue management at its parks around the world, said Marilyn Waters, director of media relations at Walt Disney Imagineering.

Social justice

Fair play — or the idea of first come, first served — is at the heart of most successful queues. It’s one of the reasons most banks, airlines and fast-food restaurants have switched from several open lines that force customers to choose the line they think is moving fastest, to a single serpentine line, which guarantees first come, first served, Larson said.

Violation of fair play can lead to “queue rage.” Larson himself became interested in queuing psychology after a frustrating experience he calls the “red bike incident.”

The Right Stuff- Astronaut’s Challenge

How much would it take to convince you to spend three months lying in bed. Three months in which the overwhelming majority of your day would be spent lying down. Eating, drinking, sleeping etc.

CNN has the story about one man who did so in the name of science.

“We know that bone loss in space is an extremely significant problem. Astronauts lose about 10 times more bone every month than a postmenopausal woman on Earth loses,” says Dr. Peter Cavanagh, former director of the Cleveland Clinic Center for Space Medicine. Bone loss occurs presumably because astronauts don’t get enough load-bearing exercise in zero gravity. Cavanagh says that their findings may later contribute to new treatments for the millions of Americans
who suffer from osteoporosis.

Roderick Jones is doing his part to help further the field of skeletal health by staying in bed — for 84 days straight.

The 40-year-old chemist was in between jobs when he saw a curious ad on the Internet. He recalls reading, “Do you have projects you’d like to complete. Would you like a small vacation while you’re actually helping the NASA space program?” Rod had always been a science fiction fanatic. A chemist by trade, he was in between jobs and trying to save for a family move from Ohio to Georgia. After several interviews, physiological and psychological tests, it was determined that Rod had the right stuff.

For three months straight, Rod lay not only in a horizontal position, but with his body tilted 6 degrees towards his head. Most of his days were filled with watching television, surfing the Web and writing in a log he called the, “Bedpan Chronicles” named for what he deemed to be one of the toughest parts of the assignment. He ate, slept, read, typed, talked on the phone, and drank — all
while lying down.His compensation for being bed bound for 12 weeks? $12,000 for the entire
project. Rod is the twelfth study subject, and NASA is halfway through the project. Cavanagh points out how difficult enrollment has been, “So far, for every 300 applicants, only one person has the right stuff.”

Researchers claim that lying at a 6-degree angle is the best way to simulate zero gravity, here, on Earth. This simulation doesn’t come cheap. NASA estimates that placing one subject in bed for a period of three months or so costs about a quarter of a million dollars.”

Medical Technology- The future is now

In my travels throughout the web I often search for interesting gadgets and inventions that will change our lives. A while back I stumbled onto MedGadget. It is an interesting site that discusses technological advances in medicine.

Here are a couple of things that caught my eye:
MIT Technology Review is reporting on new metal and polymer microgrippers that can be chemically activated to grab or cut tissue deep within the body without requiring any incisions. The scientists that developed the device envision swallowing a bunch of these and then guiding the particles using magnets to specific spots in the body for microsurgeries or doing biopsies.

From MIT Tech Review:

A gripper based on the current design could respond autonomously to chemical cues in the body. For example, it might react to the biochemicals released by infected tissue by closing around the tissue, so that pieces can be removed for analysis.
Gracias [David Gracias, biomolecular and chemical-engineering professor at JHU] and his colleagues presented the microgripper at the American Chemical Society meeting earlier this month. To demonstrate the device, they used it to grasp and maneuver tiny beads and clumps of cells in a petri dish. They have also used the device in the laboratory to perform an in vitro biopsy on a cow’s bladder. “This is the first micromachine that has been shown convincingly to do very useful things,” Gracias says. “And it does not require electric power for operation.”

The open gripper is 500 micrometers (0.05 centimeters) in diameter, and it is made of a film of copper and chromium covered with polymer. As long as the polymer stays rigid, the gripper remains open. But introducing a chemical trigger or lowering the temperature causes the polymer to soften, actuating the gripper’s fingers so that they curl inward to form a ball that is 190 micrometers wide. Another chemical signal can be used to reopen the gripper. All of the chemicals used as triggers in experiments are harmless to the body.

And the ReWalk Exoskeleton which helps paralyzed people walk again. It is made by an Israeli company called Argo Medical Technologies. I think this is just very cool.

ReWalkâ„¢, the first commercially viable upright walking assistance tool, enables wheelchair users with lower-limb disabilities to stand, walk, and even climb stairs. For potentially millions of wheelchair users.

Painful News Or News About Pain

Live Science is one of my regular reads. They usually have several articles that I find to be of interest. Here is an excerpt from an article about pain.

3. Migraines and sex go together

It may not eliminate the phrase “Not tonight, honey …” but a 2006 study found that migraine sufferers had levels of sexual desire 20 percent higher than those suffering from tension headaches. The finding suggests sexual desire and migraines might be influenced by the same brain chemical, and getting a better handle on the link could lead to better treatments, at least for the pain portion of the equation.

4. Women feel more pain

Any man who has watched a woman having a baby without using drugs would swear that women can tolerate anything. But the truth is, guys, it hurts more than you can imagine. Women have more nerve receptors than men. As an example, women have 34 nerve fibers per square centimeter of facial skin, while men average just 17. And in a 2005 study, women were found to report more pain throughout their lifetimes and, compared to men, they feel pain in more areas of their body and for longer durations.

5. Some animals don’t feel our pain

Animal research could offer clues to eventually relieve human suffering. Take the naked mole rat, a hairless and nearly blind subterranean creature. A study this year found it feels neither the pain of acid nor the sting of chili peppers. If researchers can figure out why, they might be on the road to new sorts of painkilling therapies for humans. In 2006, scientists found a pathway for the transmission of chronic pain in rats that they hope will translate into better understanding of human chronic pain. Lobsters feel no pain, even when boiled, scientists said in a 2005 report that is just one more salvo in a long-running debate.
