Scientists Cast Doubt on TSA Tests of Full-Body Scanners

by Michael Grabell ProPublica, May 16, 2011, 2:11 p.m.
The Transportation Security Administration says its full-body X-ray scanners are safe and that radiation from a scan is equivalent to what's received in about two minutes of flying. The company that makes them says it's safer than eating a banana [1].
But some scientists with expertise in imaging and cancer say the evidence made public to support those claims is unreliable. And in a new letter [2] sent to White House science adviser John Holdren, they question why the TSA won't make the scanners available for independent testing by outside scientists.
The machines, which are designed to reveal objects hidden under clothing, have the potential to close a significant security gap for the TSA because metal detectors can't find explosives or ceramic knives, which can be just as sharp as the box cutters that hijackers used on 9/11.
They are also important for TSA's public relations battle over the alternative, the "enhanced pat-down," which has bred an epidemic of viral videos: A 6-year-old girl [3] is touched from head to toe. A former Miss USA [4] says she was violated. A software programmer warns a screener, "If you touch my junk [5], I'm going to have you arrested."
After the underwear bomber tried to blow up a Northwest Airlines plane on Christmas Day 2009, the TSA ramped up deployment of full-body scanners and plans to have them at nearly every security line by 2014.
There are two types of body scanners [6]. Millimeter wave machines emit a radio frequency similar to cellphones. Backscatters work like a fast-moving X-ray. In the latter, the rays bounce off the skin and create a fuzzy white image [7] of the passenger's body. Because the beam doesn't go through the body, most of its radiation is received by the skin.
The TSA says the backscatter technology has been evaluated by the Food and Drug Administration [8], the National Institute for Standards and Technology [9] and the Johns Hopkins University Applied Physics Laboratory [10]. Survey teams are using radiation-detecting dosimeters to check the machines at airports. The TSA says the results have all confirmed that the scanners don't pose a significant risk to public health.
According to the agency and many radiation experts, the dose is so low, even for children or cancer patients, that someone would have to pass through the machines more than a thousand times before approaching the annual limit set by radiation safety organizations.
But the letter to the White House science adviser, signed by five professors at University of California, San Francisco, and one at Arizona State University, points out several flaws in the tests. Studies published in scientific journals in the last few months have also cast doubt on the radiation dose and the machines' ability to find explosives.
A number of scientists, including some who believe the radiation is trivial, say more testing should be done given the government's plans to put millions of passengers through the machines. And they have been disturbed by the TSA's reluctance to do so.
"There's no real data on these machines, and in fact, the best guess of the dose is much, much higher than certainly what the public thinks," said John Sedat, a professor emeritus in biochemistry and biophysics at UCSF and the primary author of the letter.
The same group stirred controversy last year when it sent a letter to Holdren [11] arguing that while the overall dose to the body may be low, the TSA hadn't quantified the dose to the skin. Last fall, FDA and TSA officials released a study [12] that estimated the dose to the skin to be twice the dose to the body, though still extremely low.
In the most recent letter sent to Holdren on April 28, the professors note that the Johns Hopkins lab didn't test an actual airport machine. Instead, the tests were done on a model built by the manufacturer, Rapiscan [13], and configured to resemble a system previously tested by the TSA.
The researchers' names have been kept secret, and the report on the tests is so "heavily redacted" that "there is no way to repeat any of these measurements," they wrote.
The physics and medical professors also took issue with the device used to measure the radiation. Although the device, known as an ion chamber, is commonly used to test medical equipment, they argue that the detector gets overwhelmed by the amount of radiation the backscatter deposits in a short time and might not provide accurate readings.
Helen Worth, a spokeswoman for the Johns Hopkins lab, referred questions to the TSA.
Part of the trouble is that there is no ideal device for measuring the radiation dose given by backscatter X-rays, said David Brenner, director of the Columbia University Center for Radiological Research. The machines emit a pencil beam that rapidly moves across and up and down the body, he said.
"We are one of the oldest and biggest radiological research centers in the country, and we find this to be a very hard technical problem," said Brenner, who was not involved with the letter.
Another issue is that there is a lot of uncertainty with the model used to estimate cancer risk from radiation exposure to the skin, said Rebecca Smith-Bindman, a UCSF radiologist who also was not involved in the letter.
Smith-Bindman, who has testified before Congress about excessive radiation from medical scans, studied the TSA reports and said she wasn't concerned about the airport X-rays.
The risks are "truly trivial," she wrote in an article [14] for the Archives of Internal Medicine. A passenger would have to undergo 50 airport scans to reach the level of a dental X-ray, 1,000 for a chest X-ray, and 4,000 for a mammogram.
Though imperfect, the available models predict that the backscatters would lead to only six cancers over the course of a lifetime among the approximately 100 million people who fly every year, Smith-Bindman concluded.
"There's really unnecessary fear related to these scans," she said. "What I'm not as comfortable with is that there has not been access to these machines. They are not being tested on the same regulatory basis that we see on medical equipment."
After her article was published, Smith-Bindman was contacted by a TSA public affairs officer. During the conversation, she suggested that she or other outside scientists be allowed to test the machine. The official was shocked by the suggestion and said such access could tip off people who want to avoid detection, Smith-Bindman said.
"It was not appreciating that there's legitimate scientific questions that have to be balanced against the security questions," she said.
The TSA did not respond to ProPublica's questions about why it wouldn't allow outside testing. But at a congressional hearing [15] in March, Robin Kane, assistant administrator for security technology, said doing so would expose a lot of sensitive information the agency wouldn't normally share publicly. The machines had already been tested several times, he said, and if set up securely, the agency would allow more testing.
The available information leaves scientists with little to work with. Peter Rez, the Arizona State physics professor who signed the letter to Holdren, has tried to calculate the radiation by examining the handful of backscatter images that have been released publicly.
The Electronic Privacy Information Center [16], a civil liberties group, sued the Department of Homeland Security, TSA's parent agency, in federal court seeking release of 2,000 backscatter images used in testing. But it has not been successful.
The few images that have been made public do not reveal faces or detailed private features. The TSA says the images Rez used are out of date, but Rez says the current image on TSA's website is unusable.
Using the earlier images, Rez concluded [17] in the Radiation Protection Dosimetry journal that it was highly unlikely the machines could have produced such high-quality images with doses of radiation as low as those described by TSA. He estimated the dose, while still very small, is 45 times higher than the results measured by Johns Hopkins.
Applying Rez's numbers, Brenner wrote a paper [18] for the journal Radiology, estimating that 100 additional cancers would develop for every 1 billion scans.
For Rez, the real danger occurs if the machine stops in the middle of a scan, allowing the beam to focus on a tiny area for several seconds. Given that the backscatter works with a wheel rotating at a high speed, and that the agency plans to use the scanners continuously 365 days a year, mechanical failures are likely, he said.
The TSA says that the scanners have safety systems, such as automatic shutoffs and emergency stop buttons, that will kill the beam in the event of any problem that could result in abnormal radiation. How those fail-safe systems work isn't entirely clear.
When Johns Hopkins researchers visited the Rapiscan facility, the automatic termination appeared to work. But the full results of the shutoff tests are redacted.
What's more, the test system didn't have an emergency stop button.

The Transportation Security Administration announced Friday that it would retest every full-body X-ray scanner that emits ionizing radiation — 247 machines at 38 airports — after maintenance records on some of the devices showed radiation levels 10 times higher than expected. Complete article

Is there something that tells you this may be too little, too late?  Typical government approach.

21 December 2010 -  NO Proof Scanner Are Safe

If you believe the government, you have little to worry about from the radiation beam flitting over the front and back of your body in airport watchdogs' search for explosives and other hidden implements of terror this holiday season.


The Transportation Security Administration says that when working properly, the backscatter Advance Imaging Technology X-ray scanners emit an infinitesimal, virtually harmless amount of radiation.


The problem is that the TSA offers no proof that anyone is checking to see if the machines are "working properly."  Complete article

17 December - Leading Scientists Say Airport Full Body Scanners Easily Duped

by Fran Golden

Two respected scientists say they have discovered a flaw in airport full body scanners that could potentially allow terrorists to outsmart the machines.

In research published in the Journal of Transportation Security, physicists Leon Kaufman and Joseph W. Carlson of the University of California San Francisco say body scanner machines can easily be duped.


While the purpose of the scanners is to find contraband hidden on the body, some weapons and explosives would not be visible to the devices say the researchers, who are known for their work in creating magnetic resonance imaging (MRI) machines used in hospitals.


That's because the human body and benign objects add "structured noise that interferes with signal averaging," the scientists say.


A "pancake" of explosives with beveled edges, taped to the abdomen, for instance, "would be invisible to this technology, ironically, because of its large volume, since it is easily confused with normal anatomy," the scientists report.


"It is also easy to see that an object such as a wire or a boxcutter blade, taped to the side of the body, or even a small gun in the same location, will be invisible," Kaufman and Carlson write.


Increasing radiation exposure to get a better image from the body scanning technology won't help, the scientists say. "Even if exposure were to be increased significantly, normal anatomy would make a dangerous amount of plastic explosive with tapered edges difficult if not impossible to detect."


In reaching their conclusions, the scientists used simulations (computational algorithms). They refer in their research to some photos of full body scanners not deployed in the U.S., but used at airports elsewhere.


The Transportation Security Administration (TSA) responds to the latest report with the same pat response it has given to other criticism about full body scanners, a spokesman telling AOL Travel News, "While there is no silver bullet, advanced imaging technology is a proven, highly-effective tool that safely detects both metallic and non-metallic items concealed on the body that could be used to threaten the security of airplanes."


The TSA adds that full body scanners are just one of the airport security methods it has in place.


Critics of full body scanners have raised privacy concerns about "naked" images and questioned whether radiation from the machines could potentially pose a cancer risk, among other things.


This week the TSA also took steps to debunk a rumor that airport body scanner images of "Baywatch" star Donna D'Errico -- who has criticized the TSA for singling out attractive celebrities to go through body scans – are in circulation. The TSA says it's impossible for anyone to capture scanner images given safeguards it has in place.

Dr. Blaylock: Body Scanners More Dangerous Than Feds Admit
Wednesday, November 24, 2010 9:58 AM
By Dr. Russell Blaylock. a nationally recognized board-certified neurosurgeon


The growing outrage over the Transportation Security Administrations new policy of backscatter scanning of airline passengers and enhanced pat-downs brings to mind these wise words from President Ronald Reagan: The nine most terrifying words in the English language are: Im from the government and Im here to help you.
So, what is all the concern really about - will these radiation scanners increase your risk of cancer or other diseases? A group of scientists and professors from the University of California at San Francisco voiced their concern to Obama's science and technology adviser John Holdren in a well-stated letter back in April.
The group included experts in radiation biology, biophysics, and imaging, who expressed serious concerns about the dangerously high dose of radiation to the skin.
Radiation increases cancer risk by damaging the DNA and various components within the cells. Much of the damage is caused by high concentrations of free radicals generated by the radiation. Most scientists think that the most damaging radiation types are those that have high penetration, such as gamma-rays, but in fact, some of the most damaging radiation barely penetrates the skin.
One of the main concerns is that most of the energy from the airport scanners is concentrated on the surface of the skin and a few millimeters into the skin. Some very radiation-sensitive tissues are close to the skin - such as the testes, eyes, and circulating blood cells in the skin.
This is why defenders using such analogies as the dose being 1,000-times less than a chest X-ray and far less than what passengers are exposed to in-flight are deceptive. Radiation damage depends on the volume of tissue exposed. Chest X-rays and gamma-radiation from outer space is diffused over the entire body so that the dose to the skin is extremely small. Of note, outer space radiation does increase cancer rates in passengers, pilots, and flight attendants.
We also know that certain groups of people are at a much higher risk than others. These include babies, small children, pregnant women, the elderly, people with impaired immunity (those with HIV infection, cancer patients, people with immune deficiency diseases, and people with abnormal DNA repair mechanism, just to name a few).
As we grow older, our DNA accumulates a considerable amount of unrepaired damage, and under such circumstances even low doses of radiation can trigger the development of skin cancers, including the deadly melanoma. I would also be concerned about exposing the eyes, since this could increase ones risk of developing cataracts.
About 5 percent of the population have undiagnosed abnormal DNA repair mechanism. When exposed to radiation, this can put them at a cancer risk hundreds of times greater than normal people.
It also has been determined that when skin is next to certain metals, such as gold, the radiation dose is magnified 100-fold higher. What if you have a mole next to your gold jewelry? Will the radiation convert it to a melanoma? Deficiencies in certain vitamins can dramatically increase your sensitivity to radiation carcinogenesis, as can certain prescription medications.
As for the assurances we have been given by such organization as the American College of Radiology, we must keep in mind that they assured us that the CT scans were safe and that the radiation was equal to one chest X-ray. Forty years later we learn that the dose is extremely high, it is thought to have caused cancer in a significant number of people, and the dose is actually equal to 1,000 chest X-rays.
Based on these assurances, tens of thousands of children have been exposed to radiation doses from CT scanners, which will ruin the children's lives. I have two friends who were high-ranking Environmental Protection Agency scientists, and they assure me that in government safety agencies, politics most often override the scientists real concerns about such issues.
This government shares House Speaker Nancy Pelosis view when she urged passage of the Obamacare bill sight unseen - Lets just pass the bill, and we will find out what is in it later.
When the real effects of these scanners on health become known, Secretary of Homeland Security Janet Napolitano and the rest of the gang who insist the scanners are safe will be long gone.

(November 26) --  I started covering the issue of the airport x-ray scanner four years or so ago.  Since that time many have hopped on the band wagon to speak out against this intrusive, expensive, and health-risky device.  Most researchers now tell us that it isn't really as effective as Chertoff and his minions wish you to believe.

Dressing for Scanners  Daisy Nguyen, Associated Press, November 23, 2010

LOS ANGELES (AP) -- It was no crime of fashion, but Wendy Gigliotti's bulky sweater and ankle-length skirt made her a target of airport screeners.
A female Transportation Security Administration officer at Sacramento International Airport told her, "We can't tell if there's something under your skirt." She was then frisked in a way she said felt more intrusive than a physical exam.
"I felt not only like a criminal, I felt absolutely violated," said Gigliotti.
Gigliotti is among the travelers feeling mortified or even outraged by the more thorough security pat-downs the TSA began using this month as the holiday travel season begins.
Travel experts say the new scrutiny underscores the need for better airport fashion choices that can help people breeze through screenings with their dignity intact.

Man Sues TSA, Claims Pat-Down Violates His Rights

An Arkansas man is taking the Transportation Security Administration to court, claiming new screening searches violate the Constitution.


Robert Dean filed a federal lawsuit in Little Rock this week, even though the city's airport doesn't have the new scanners that have sparked outrage across the country. Dean's suit asks for a federal ban against the machines and full-body searches.


On a recent trip to Chicago, Dean claims that being subjected to a full-body scan and being patted down by TSA personnel harmed his "emotional, psychological and mental well-being," The Associated Press reported.
The security agency said it does not comment on pending litigation, according to the AP.


"Filing for an injunction will stop these types of invasive measures until we can get a ruling on the constitutionality of this," Dean said, according to FOX 16 TV in Arkansas.


The invasive procedures violate the Fourth Amendment protection against unreasonable searches and seizures, Dean says.


"The physical aspects of it weren't that traumatic," he said of his experience in Chicago. "I think it's the thought of somebody sitting behind a screen looking at your naked body doing these examinations," he told KTHV TV in Little Rock.

The body scanners, increasingly found in airports, courthouses and other places where security is high, use an assortment of technologies. These include millimeter wave scanners (shown below) — in which the subject is harmlessly pelted with extremely high frequency radio waves which reflect a picture back to the device — and backscatter X-ray (shown above) — which measures low-powered reflective X-rays to produce clearer body shots, shots that can reveal alarmingly precise anatomical detail. According to CNET, the U.S. Marshals Service admitted this week that it had saved thousands of images that had been recorded from a security checkpoint in a Florida courthouse. The revelation comes at a tense time. Two weeks ago, when Homeland Security Secretary Janet Napolitano said such scanners would appear in every major airport, privacy advocates such as the Electronic Privacy Information Center in Washington D.C. filed a lawsuit to stop the device rollout. The reason? Because the devices were "designed and deployed in a way that allows the images to be routinely stored and recorded," EPIC executive director Marc Rotenberg told CNET, adding that this "is exactly what the Marshals Service is doing." As CNET's Declan McCullagh explains, it's the mystery of the devices' potential that is most unnerving: "This trickle of disclosures about the true capabilities of body scanners — and how they're being used in practice — is probably what alarms privacy advocates more than anything else," he wrote. The TSA maintains that body scanning is "constitutional" and the CNET 7/17/10 New body-scanner software to show only stick figures Boston's Logan International Airport hopes to be the first airport in the country to get new software that should eliminate privacy concerns over full-body scanners at security checkpoints. The software would produce stick-figure images of passengers instead of the more revealing images currently viewed by operators at remote stations. The software would detect suspicious objects on passengers that require further attention - such as possible weapons or explosives - allowing Transportation Security Administration screeners and explosive weapons specialists to hone in on them and determine whether they pose a danger. 6/29/10  Airport body scanners deliver radiation dose 20 times higher than first thought, warns expert: June 29, 2010 Airport body scanners deliver radiation dose 20 times higher than first thought, warns expert 30 Jun 2010 Full body scanners at airports could increase your risk of skin cancer, experts warn. The X-ray machines have been brought in at Manchester, Gatwick and Heathrow.

Germany says full-body airport scanner "nonsense" BERLIN (Reuters) - Germany will not participate in EU proposals for airports to use full-body scanner security checks, which have raised privacy issues, its interior ministry said on Friday. "I can tell you in all clarity that we will not take part in this nonsense," a spokeswoman for the interior ministry told a regular news conference. The executive European Commission proposed last month to add body scanners to a list of security measures that can be used at airports in the 27-country bloc. EU lawmakers criticized the scanners in a resolution on Thursday, saying they were equivalent to "a virtual strip search" and raised serious human rights concerns. The lawmakers called for a detailed study of the technology before it is used. The Commission says a number of EU states including the Netherlands already use body scanners and the EU executive wanted to harmonize conditions in which they can be operated. The scanners do not exist at German airports and have sparked vivid criticism by politicians across the political spectrum.

Garlic Gives You That Sulfur

UPDATE: 20 August, 2010 -  Garlic to lower blood pressure

Garlic was once used to combat the Black Death, but doctors now claim it can tackle a modern-day epidemic of heart disease.
Just 12 weeks' treatment with garlic tablets led to a 'significant' cut in blood pressure, slashing the risk of a heart attack or stroke.
Researchers claim people with hypertension, the medical term for high blood pressure, could control their condition better by adding garlic to conventional medication. Read complete article

My comment to this article is that it is good information except for the misunderstanding that the researchers focus on standardized supplements rather than food based products.  We recommend you consider using the garlic you'll find in the right column, or Immortal Garlic or our specific unique garlic.

Lower levels of 'rotten egg' gas (hydrogen sulfide) in blood linked to obesity, type 2 diabetes and poorer circulation

ScienceDaily (2010-04-28) -- Researchers have for the first time identified a link between blood levels of the gas hydrogen sulfide (a gas more commonly associated with the smell of rotten eggs), obesity and type 2 diabetes. ... > read full article

For several decades I've offered clients a garlic supplement that is known for reducing blood pressure. Now it seems that we need to wait for some new recombinant drug because of another medical study that overlooks the natural and known natural remedies.

Sulfur is one of the most important healing molecules we have known of and used in natural therapies for eons. It is mentioned in this 'special form' in my book, "Blood Pressure Care Naturally".

Oh, for the day when these folks get to recall all of the pharmacopoeia that first came from Mother Nature.

'Fart gas' link to blood pressure
The gas best known for being used in many stink bombs may also control blood pressure, say US researchers.

Small amounts of hydrogen sulphide - a toxic gas generated by bacteria living in the human gut - are responsible for the foul odour of flatulence.

But it seems the gas is also produced by an enzyme in blood vessels where it relaxes them and lowers blood pressure.

The findings in mice may lead to new treatments for high blood pressure, the Science journal reported.

Researchers at Johns Hopkins University, in Maryland, found that the gas is produced in the cells lining blood vessels by an enzyme called CSE.

We know hydrogen sulphide is not good for us at high levels but it seems that at the lower levels in the body it is essential
Professor Amrita Ahluwalia

In mice engineered to be deficient in this enzyme, levels of hydrogen sulphide were almost depleted compared with levels in normal mice.

The CSE-deficient mice also had blood pressure measurements about 20% higher than the normal mice, comparable to serious hypertension in humans.

When the engineered mice were given a drug which relaxes normal blood vessels - methacholine - there was no difference, indicating the gas is responsible for the relaxation.

Treatments

Another gas, nitric oxide, is already known to be involved in control of blood pressure.

Researcher Dr Solomon Snyder said: "Now we know hydrogen sulphide's role in regulating blood pressure, it may be possible to design drug therapies that enhance its formation as an alternative to the current methods of treatment for hypertension."

Professor Amrita Ahluwalia, an expert in vascular pharmacology at Barts and The London Medical School, said: "This study shows that smelly hydrogen sulphide is also likely to have a role in regulating blood pressure and it will be a bit of an impetus for scientists to develop more specific tools to work out what's going on.

"We know hydrogen sulphide is not good for us at high levels but it seems that at the lower levels in the body it is essential."

Dr Allan MacDonald, a reader in pharmacology at Glasgow Caledonian University, said: "Treatments based on hydrogen sulphide could become important in a variety of cardiovascular diseases," he said.

Green Living: Making Your Own Non-Toxic Cleaners

Back in 1991 I started teaching a series of classes under the broad heading of "Green Living". The classes came as the result of the naturally oriented column I was writing at that time and some local presentations in and around the Puget Sound region.

Probably one of my most popular classes from that time is one where I talk about all the ingredients in mass market cleaners and why they are not health promoting.

During this program I teach how to clean just about anything you can imagine with a select few ingredients, bought cheaply at the supermarket or in bulk if you know where to access these in your local area.

Of course now the big producers of mass market cleaners are flooding the market with their brands hoping you'll keep up their $10 billion market share. While these products aren't totally toxic, under the guise of green they still include some known irritants and toxins.

Generally most people aren't as interested as I am in reading the chemical index, a standard resource for the cleaning products and HABA crowd. You can find this in the library and you'd really be amazed and what you find. You can also look up things under MSDS (material safety data sheet) system.

The problem is that while single items may be "approved" the mixtures resulting from adding two or more ingredients together are not required to be tested for health or environmental risks.

Back at that time we prepared one of our Healthy Handouts© on the topic of making your own cleaning products. This might be something you'd like to purchase as it seems that you can save - on the average - over $400 a year doing some very simple things along these lines.

Long before you heard the mainstream push to promote CFL bulbs we warned of the mervury/hazardous waste risk that seemed to be ignored by most venues.

At the same time we've warned against CFL bulbs we've educated for the switch to LED light blubs or PAR halogen types.

Now it seems that E and Daily Green have taken our heed. Mind you we have written tro them in the past about LED, while they still were promoting CFL and not paying such close attention to the hazards.

Yes LED are more costly initially the cost should come down once more people start buying them. However, over the long term, LED blubs are much more cost effective.

As we say, we are usally well ahead of the curve on health news and its impact on you, as well as often copied but never duplicated.

Want Energy Efficient, Mercury-Free LED Light Bulbs for Your Home?
Recent Technology Lights the Way to a Greener Future

Dear EarthTalk: What's the story with LED light bulbs that are reputed to be even more energy-efficient than compact fluorescents?--

Perhaps the ultimate "alternative to the alternative," the LED (light-emitting diode) light bulb may well dethrone the compact fluorescent (CFL) as king of the green lighting choices. But it has a way to go yet in terms of both affordability and brightness.

LEDs have been used widely for decades in other applications -- forming the numbers on digital clocks, lighting up watches and cell phones and, when used in clusters, illuminating traffic lights and forming the images on large outdoor television screens. Until recently LED lighting has been impractical to use for most other everyday applications because it is built around costly semiconductor technology. But the price of semiconductor materials has dropped in recent years, opening the door for some exciting changes in energy-efficient, green friendly lighting options.

According to HowStuffWorks.com, LED bulbs are lit solely by the movement of electrons. Unlike incandescents, they have no filament that will burn out; and unlike CFLs, they contain no mercury or other toxic substances. Proponents say LEDs can last some 60 times longer than incandescents and 10 times longer than CFLs. And unlike incandescents, which generate a lot of waste heat, LEDs don't get especially hot and use a much higher percentage of electricity for directly generating light.

But as with early CFLs, LED bulbs are not known for their brightness. According to a January 2008 article in Science Daily, "Because of their structure and material, much of the light in standard LEDs becomes trapped, reducing the brightness of the light and making them unsuitable as the main lighting source in the home." LED makers get around this problem in some applications by clustering many small LED bulbs together in a single casing to concentrate the light emitted. But such LED "bulbs" still don't generate light much brighter than a 35-watt incandescent.

If LEDs are going to replace incandescents and CFLs, manufacturers will have to make them brighter. EarthLED is lighting the way with its EvoLux and ZetaLux bulbs, which use multiple LEDs in a single casing to generate light. The EvoLux delivers light equal to that of a 100-watt incandescent, the company says. But the $80/bulb price tag may be tough to swallow. The ZetaLux, which retails for $49.99, delivers light equivalent to a 50- or 60-watt incandescent, will last 50,000 hours and costs only $2/yearly to run.

Other bulb makers are working on similar designs for high-powered LED bulbs, hoping that an increase in availability will help spur demand, which will in turn lower prices across the board. Until then, consumers can find LED bulbs suitable for secondary and mood lighting purposes in many hardware and big box stores. C. Crane's 1.3-watt LED bulb, for example, generates as much light as a 15-watt incandescent bulb. Check your local hardware store for other options, as well as online vendors such as Best Home LED Lighting, Bulbster, SuperBrightLEDs.com and We Love LEDs.

Beware, genetically engineered and newer biological drugs

There is a rather well publicized issue surrounding multiple myeloma and the possibility of symptomatic treatment from a drug in this class that is approved for MS and Crohn's Disease. One of the serious side effects of the drug is that it can cause multiple myeloma and a very severe bacterial invasion of brain tissue that can be fatal. The drug is listed on the FDA's drug advisory information pages. These are reasons why the drug is so tightly controlled. Another may be that the effects of the drug really isn't known because no long term studies are completed before FDA approval and marketing.

Humira and other arthritis drugs have been worrisome for years, the risk of cancer has been raised, yet they are still plentifully prescribed.

Some forms of arthritis are well known to be associated with food allergy but this concept is absent or fleeting over (knee-jerk) consideration for promoting the drug.

Some cases of Chrohn's may be helped with more nutritional and natural approaches to revitlize the gut lining and function. Now this is a novel idea in MSM but its one I've seen work time and time again.

MS and multiply myeloma can be helped with more natural approaches too.

There just needs to be a better approach to health care.

Safety a problem for new generation drugs, tooBy LINDSEY TANNER, AP Medical Writer

He said the results simply show that doctors and patients should be aware that the drugs have many potential side effects that may not be listed on the label.

CHICAGO – Nearly a fourth of widely used new-generation biological drugs for several common diseases produce serious side effects that lead to safety warnings soon after they go on the market, the first major study of its kind found.

Included in the report released Tuesday were the arthritis drugs Humira and Remicade, cancer drugs Rituxan and Erbitux, and the heart failure drug Natrecor. All wound up being flagged for safety.

That might surprise some doctors who may have thought that these new treatments might be safer than traditional chemical-based medicines.

Researchers found that most of the warnings came within five years after these biologicals won government approval in the United States and Europe between 1995 and 2007.

Many traditional medicines wind up with safety warnings too after they go on the market. But experts said there were no similar studies of older medicines that made it possible to compare safety issues between the two groups of drugs.

The new study, by Dutch researchers, is the first comprehensive examination of these newer medicines, a driving part of the biotech revolution.

The drugs are known as biologicals because they're made from living material and they typically affect the body's disease-fighting immune system. Many relieve severe symptoms by suppressing that system.
It's that same mechanism that can result in side effects often not seen with traditional chemical-based medicines, said Dr. Charles Bennett, a Northwestern University drug safety expert. These can include brain and fungal infections and cancer.

Many are genetically engineered and Bennett said that because they typically resemble naturally occurring proteins, many doctors have assumed they were safer than traditional chemical-based medicines. But he said the study shows that's not necessarily true.

"They have an important role," Bennett said. "They're really the next generation of pharmaceuticals."

He said the results simply show that doctors and patients should be aware that the drugs have many potential side effects that may not be listed on the label.

Among the drugs under examination are Genentech Inc.'s psoriasis drug Raptiva, which just last week the Food and Drug Administration warned may contribute to a life-threatening brain illness and infections; and Exubera, an inhaled insulin product, linked with lung cancer risks. Exubera was approved by the FDA in 2006 but Pfizer Inc. stopped selling it last year.

The study appears in Wednesday's Journal of the American Medical Association.

It involved 136 biologics approved in the United States and 105 in the European Union between January 1995 and June 2007. A total of 41, or nearly 24 percent, got safety warnings issued through June 2008.

The results are a concern, and they underscore the need for closer scrutiny of drugs after their approval, said lead author Thijs Giezen of the University of Utrecht.

But he said the study also is reassuring because most problems showed up relatively soon after the drugs became available, which minimized the potential for widespread harm.

"If most issues are discovered within the first few years, then the system is working," Giezen said.

Bennett says it's unreasonable to think that the studied drugs' safety issues should have been discovered before they were marketed. That's because drug approval is based on relatively small studies with patients who generally are healthier than those in the general population. It often takes real-world experience for side effects to appear, he said.

Many biological drugs have advantages over conventional medicine, but the study shows their risks need to also be considered, said Thomas Moore of the Institute for Safe Medication Practices.

For example, non-steroid arthritis medicines including ibuprofen can reduce pain by decreasing inflammation, but they can cause stomach bleeding.

Biologic rheumatoid arthritis medicines Remicade, Enbrel and Humira are designed to ease painful joints by keeping the body's immune system from attacking itself, the underlying problem in the disease. But they are much more expensive and have been linked with higher risks for potentially fatal infections. Also, the FDA is investigating possible cancer risks.

"My message to patients is that these biological products often can treat very difficult to treat diseases but may have very substantial risks and that you need to take extra care to educate yourself as to what those risks might be," Moore said.

And in another report on this timely topic -

Reports of serious drug reactions hit recordBy RICARDO ALONSO-ZALDIVAR, Associated Press Writer

WASHINGTON – The number of serious drug reactions and deaths reported to the government shot up in the first three months of this year to set a new record, a health industry watchdog group said Wednesday.

The Food and Drug Administration received nearly 21,000 reports of serious drug reactions, including more than 4,800 deaths, said an analysis of federal data by the Institute for Safe Medication Practices.

Two drugs accounted for a large share of the latest reports. One was the blood thinner heparin. Most of the drug's problems were prompted by tainted heparin imported from China. The other was Chantix, a new kind of anti-smoking drug from Pfizer.

Chantix, which had the most reports of any medication, works directly in a smoker's brain to ease withdrawal symptoms. It also blocks the pleasurable effects of nicotine if the patient is tempted to light up again. Earlier this year, the FDA warned that Chantix may be linked to psychiatric problems, including suicidal behavior and vivid dreams. Pfizer said Wednesday it stands by Chantix, and that the volume of reports might be linked to publicity about the side effects.

"The FDA is aware of the increasing number of reports, and we take them seriously," said spokesman Christopher DiFrancesco. But officials are not sure whether reports are up because problems are getting worse, or simply due to greater awareness about drug safety issues.

The watchdog group that prepared the analysis has served hospitals and pharmacists for years as a clearinghouse for information on medication errors. Known as ISMP, the organization is now trying to reach consumers with regular reports on drug safety trends.

"We believe that one of the most important tools to promote is to monitor trends on a regular basis," said Thomas J. Moore, a senior scientist with ISMP. "Knowing which drugs are causing injuries and how many people are being hurt is the raw material we need to fashion sound measures to promote patient safety."

The FDA defines serious drug reactions as ones that cause hospitalization, require medical intervention, or place a life in jeopardy. The agency's monitoring system relies on voluntary reports from doctors and is only believed to capture a fraction of overall problems.

The 20,745 cases reported from January through March was 38 percent higher than the average for the previous four calendar quarters, and the highest for any quarter, the report said.

The number of deaths, 4,824, was a nearly threefold increase from the last calendar quarter of 2007. The FDA said heparin was largely to blame.

Previous ISMP research has shown that reports of serious drug safety problems had increased markedly since the late 1990s.

The FDA case reports provide a signal of possible problems with a drug, but a cause-and-effect connection can only be established through painstaking investigation. If the FDA were a police agency, the reports would indicate "probable cause," but not necessarily "guilt beyond a reasonable doubt."

The ISMP study found that heparin accounted for 779 reports of serious problems, including 102 deaths. The FDA, using data that covers a longer time period, has reported 238 deaths possibly linked to heparin.

Heparin "illustrates an example of a significant drug safety problem that was promptly and effectively resolved by the drug manufacturers and the FDA once the issue was detected and understood," the report said.

Not so with Chantix, it concluded.

The FDA should forcefully warn patients taking Chantix that they may have blackouts that could lead to accidents, the report said. Current warnings say patients may be too impaired to drive or operate heavy machinery, but such language is standard for many medications. The government has banned the drug for pilots.

The report found 15 cases of Chantix patients who appeared to have been involved in traffic accidents, and 52 additional cases involving blackouts or loss of consciousness. The FDA said it taking a second look at the Chantix warnings.

The agency received 1,001 reports of serious injuries linked to Chantix, more than for the 10 best-selling brand name drugs combined.

Chantix "continued to provide a striking signal of safety issues that require investigation and action," the report said. The authors acknowledged Pfizer's concern that publicity may be driving up the number of reports, but concluded there's enough evidence to warrant stronger FDA action.

Pfizer said the total sum of its Chantix data, including results from clinical trials, show the drug's benefits clearly outweigh its risks.

"We stand by the efficacy and safety profile of Chantix," the company said in a statement. "There are few things that provide greater health benefits than quitting smoking. Pfizer is committed to reducing the prevalence of smoking globally. As part of that mission, we want to increase peoples' understanding of the dangers of smoking and the benefits of quitting."

But then again we've mentioned Chantix in several other posts herein.
And if you've queries regarding more natural ways to approach stopping smoking, contact us.

Its the Potassium

Have you eaten your kale today?

I haven't yet but I'll be having a pear-kale-kiwi-lime smoothie later in my day with a scoop of Leaflady's Great Green Powder Blend added in (order from us, it is organic too!).

Potassium is one of the key nutrients for heart health, although it needs to be in balance with other vitamins and minerals.

Vegetables are the real powerhouse for minerals and vitamins along with protein when it comes to boosting your intake of these health promoting nutrients.

Fruit is good but more in moderation because of the sugar content, especially bananas. Fruit is great for fiber and it promotes cleansing. Its also best to keep from mixing fruit with vegetables, especially as found in a lot of green powder products.

Another one of my favorite things is kale salad with avocado, nori seaweed, raisins, lime juice and hemp seed oil.

Greens, greens, they're good for your heart: study
by Karin Zeitvogel

WASHINGTON (AFP) – Diets worldwide that are rich in fried and salty foods increase heart attack risk, while eating lots of fruit, leafy greens and other vegetables reduces that risk, a groundbreaking study showed.

The study, called INTERHEART, looked at 16,000 heart attack patients and controls between 1999 and 2003 in countries on every continent, marking a shift from previous studies which have focussed on the developed world.

The patients and controls filled in a "dietary risk score" questionnaire based on 19 food groups, which contained healthy and unhealthy items and were tweaked to include dietary preferences of each country taking part in the study.

The researchers found that people who eat a diet high in fried foods, salty snacks, eggs and meat -- the "Western Diet" -- had a 35 percent greater risk of having a heart attack than people who consumed little or no fried foods or meat, regardless of where they live.

People who ate a "Prudent Diet" -- high in leafy green vegetables, other raw and cooked vegetables, and fruits -- had a 30 percent lower risk of heart attack than those who ate little or no fruit and veg, the study showed.

The third dietary pattern, called the "Oriental Diet" because it contained foods such as tofu and soy sauce which are typically consumed in Asian societies, was found to have little impact on heart attack risk.

Although some items in the Oriental diet might have protective properties such as vitamins and anti-oxidants, others such as soy sauce have a high salt content which would negate the benefits, the study said.

The study was groundbreaking in its scope and because previous research had focussed mainly on developed countries, according to Salim Yusuf, a senior author of the study.

"We had focussed research on the West because heart disease was mainly predominant in western countries 25-30 years ago," Yusuf, who is a professor of medicine at McMaster University in Canada, told AFP.

"But heart disease is now increasingly striking people in developing countries. Eighty percent of heart disease today is in low- to middle-income countries" partly because more people around the world are eating western diets, he said.

"This study indicates that the same relationships that are observed in western countries exist in different regions of the world," said Yusuf, who is also head of the Population Health Research Institute at Hamilton Health Sciences in Ontario.

Patients who had been admitted to coronary care units in 262 centers around the world, and at least one control subject per patient, took part in the study.

The INTERHEART results were published Monday in Circulation, the journal of the American Heart Association.

The main countries in the study were Argentina, Brazil, Chile and Colombia in South America; Canada and the United States in North America; Sweden in western Europe; Croatia, Poland and Russia for eastern Europe; and Dubai, Egypt, Iran, Kuwait and Qatar for the Middle East.

In sub-Saharan Africa, the main countries were Cameroon, Kenya, Mozambique, South Africa and Zimbabwe; while nearly all the South Asian countries -- India, Pakistan, Bangladesh, Nepal and Sri Lanka -- took part, as did Southeast Asian countries including the Philippines and Singapore, Yusuf told AFP.

Food Allergy on the Rise

The increase in food allergy is good to make note of because of several factors.

One of course is the ever increasing level of environmental toxicity in air, water and food.

Food coloring, additives and flavorings also are known to contribute to this health concern. Over processed foods (including cereals and dairy) and the increased use of highly allergenic or GMO soy in formula, pesticide use and other GMO foods must be considered.

One issue that for the most part that is overlooked is the effect of the myriad of vaccines forced on children from birth to the teen years, on GI problems and allergy.

Over and over again I am amazed at just how the gut issues in infants and small children become more prevalent, how troubling acid antagonist drugs are thrown at them (leading to many more serious problems over time), and how the use of simple remedies like real food, enzymes and probiotics are ignored.

Even children's prescription drugs include many colorings, flavorings and artificial sweeteners - all known to impact developing gastrointestinal and immune systems.

I wonder when common sense will return to health care and mainstream medicine.

Food allergies increasing in US kids, study says By MIKE STOBBE, AP Medical Writer

ATLANTA – Food allergies in American children seem to be on the rise, now affecting about 3 million kids, according to the first federal study of the problem.

But experts said that might be because parents are more aware and quicker to have their kids checked out by a doctor.

About 1 in 26 children had food allergies last year, the Centers for Disease Control and Prevention reported Wednesday. That's up from 1 in 29 kids in 1997.

The 18 percent increase is significant enough to be considered more than a statistical blip, said Amy Branum of the CDC, the study's lead author.

Nobody knows for sure what's driving the increase. A doubling in peanut allergies — noted in earlier studies — is one factor, some experts said. Also, children seems to be taking longer to outgrow milk and egg allergies than they did in decades past.

But also figuring into the equation are parents and doctors who are more likely to consider food as the trigger for symptoms like vomiting, skin rashes and breathing problems.

"A couple of decades ago, it was not uncommon to have kids sick all the time and we just said 'They have a weak stomach' or 'They're sickly,'" said Anne Munoz-Furlong, chief executive of the Food Allergy & Anaphylaxis Network, a Virginia-based advocacy organization.

Parents today are quicker to take their kids to specialists to check out the possibility of food allergies, said Munoz-Furlong, who founded the nonprofit in 1991.

The CDC results came from an in-person, door-to-door survey in 2007 of the households of 9,500 U.S. children under age 18.

When asked if a child in the house had any kind of food allergy in the previous 12 months, about 4 percent said yes. The parents were not asked if a doctor had made the diagnosis, and no medical records were checked. Some parents may not know the difference between immune system-based food allergies and digestive disorders like lactose intolerance, so it's possible the study's findings are a bit off, Branum said.

However, the study's results mirror older national estimates that were extrapolated from smaller, more intensive studies, said Dr. Hugh Sampson, a food allergy researcher at the Mount Sinai School of medicine.

"This tells us those earlier extrapolations were fairly close," Sampson said.

The CDC study did not give a breakdown of which foods were to blame for the allergies. Other research suggests that about 1 in 40 Americans will have a milk allergy at some point in their lives, and 1 in 50 percent will be allergic to eggs. Most people outgrow these allergies in childhood.

About 1 in 50 are allergic to shellfish and nearly 1 in 100 react to peanuts, allergies that generally persist for a lifetime, according to Sampson.

Some people have more than one food allergy, he said, explaining why the overall food allergy prevalence is about 4 percent.

Children with food allergies also were more likely to have asthma, eczema and respiratory problems than kids without food allergies, the CDC study found, confirming previous research.

The study also found that the number of children hospitalized for food allergies was up. The number of hospital discharges jumped from about 2,600 a year in the late 1990s to more than 9,500 annually in recent years, the CDC results showed.

Also, Hispanic children had lower rates of food allergies than white or black children — the first such racial/ethnic breakdown in a national study.

The reason for that last finding may not be genetics, said Munoz-Furlong. She is Hispanic and said people in her own family have been unwilling to consider food allergies as the reason for children's illnesses. "It's a question of awareness," she said.

Milk Thistle

Outside of this BLOG I write a regular column that appears in several print media venues and sometimes seems to end up on the net.

I notice in review of my web site stats that often people are looking for information about liver health and gall bladder health.

While the two are very closely related, they also have different functions and sometimes what is good for one may or may not be good for the other.

This month my article was about milk thistle. To my surprise, as I was perusing articles on the Rense website, I cam across a headline that interested me.

I clicked on the link only to find the article I had just written for the specific print publication at the other end of the link.

Of course I was surprised. I also wonder who it might be in Latah County, Idaho that listens to or reads Rense.

If you aren't familiar with Idaho or Latah County, you might want to ask me off line. I lived there for a while and I have to say that life in a "Red state"is certainly more like being in a third world country. It is isolated, closed-minded, and so strange to any one who has lived elsewhere that I dubbed it "The Idaho Way". Happily there are a few folks who do understand what I mean.

Anyway, politics aside, if you'd like to read the article, Milk Thistle - A Great Friend For Your Liver, please see it here.

If it disappears and you'd like to read it, we'll be adding it to the articles on leaflady.org in the future.

I was also surprised when I received a complement from someone who writes on similar topics for another web site that has had a history of using my work for resources without giving proper credit.

He appreciated the information and told me he learned new information. I was happy he learned something, but as a health care colleague's wife often says, "Gayle forgets more than most people will ever know."

Over fifty years of a love for natural healing might give me a slight edge.

Using your mind to heal

The release of this recent repeat of older studies is very worthwhile to see reported in mainstream media.

Years ago when I worked in neuro-icu from time to time and subsequently throughout my career as a health professional I have always maintained that neurons can be regenerated. It is the basis for the effectiveness of the therapy for stroke victims to regain use of effected limbs in association with restraining the unaffected limb for short period twice daily ( you are hearing me cringe when I think of all the after effects of CVAs and head injury that are preventable with proper care).

The mind is indeed a powerful tool in healing. Many of us on the avant garde edge of health care have always believed this and integrated the teachings into our care for patients and clients. There is no reason why specific healing techniques cannot be taught to patients to encourage them to rely more on the body's inherent ability to heal. It is also an effective tool that already has been shown to assist the injured with sexual issues.

Many more applications are there, waiting for the door to open.

Perhaps this report will encourage others still relying on Newtonian thinking to burst out of the chains.

Mind power moves paralysed limbs By Michelle Roberts, Health reporter, BBC News

Scientists have shown it is possible to harness brain signals and redirect them to make paralysed limbs move.

The technology bypasses injuries that stop nerve signals travelling from the brain to the muscles, offering hope for people with spinal damage.

So far the US team from the University of Washington have only tested their "brain-machine interfaces" in monkeys.

The hope is to develop implantable circuits for humans without the need for robotic limbs, Nature reports.

Wired up

Spinal cord injuries impair the nerve pathways between the brain and the limbs but spare both the limb muscles and the part of the brain that controls movement - the motor cortex.

Similar techniques could be applied to stimulate the lower limb muscles during walking
Lead researcher Dr Chet Moritz

Recent studies have shown that quadriplegic patients - people who have paralysis in all four limbs - can consciously control the activity of nerve cells or neurons in the motor cortex that command hand movements, even after several years of paralysis.

Using a gadget called a brain-machine interface, Dr Chet Moritz and colleagues re-routed motor cortex control signals from the brains of temporarily paralysed monkeys directly to their arm muscles.

The gadget, which is the size of a mobile phone, interprets the brain signals and converts them into electrical impulses that can then stimulate muscle to contract.

By wiring up artificial pathways for the signals to pass down, muscles that lacked natural stimulation after paralysis with a local anaesthetic regained a flow of electrical signals from the brain.

Life-changing

The monkeys were then able to tense the muscles in the paralysed arm, a first step towards producing more complicated goal-directed movements, such as grasping a cup or pushing buttons, say the researchers.

Lead researcher Dr Chet Moritz said: "This could be scaled to include more muscles or stimulate sites in the spinal cord that could activate muscles in a coordinated action.

"Similar techniques could be applied to stimulate the lower limb muscles during walking."

The scientists found the monkeys could learn to use virtually any motor cortex nerve cell to control muscle stimulation - it did not have to be one that would normally controlled arm movement. And their control over the muscles improved with practice.

The researchers say they need to do trials in humans, meaning a treatment could be decades away.

Dr Mark Bacon, head of research at the UK charity Spinal Research, said: "This is clearly a step in the right direction and proves the principle that artificially transducing the will to move generated in the brain with relevant motor activity can be achieved.

"However, these results have been produced in experimental models where there is no injury per se."

He said injury-induced changes to the nerve circuits might hinder the technology's application in real life.

Also, brain-machine interfaces communicate in only one direction - in this case from the brain to the muscle.

"Sensory feedback, so important for fine control of movements and dexterity, is still some way away," he said.

Pfizer hedging its bets? UPDATE

Today Pfizer agrees to pay out $894 million to settle lawsuits over Celebrex and Bextra. Other NSAIDS still show a link to heart disease but this is one of the most readily preventable health conditions we know of and other posts on this blog give you some of that data. For pain and inflammation there are many excellent natural remedies as well as one of the natural products I use from time to time that has been tested at Dana Farber.

$894 million deal ends pain of Pfizer's lawsuitsBy Linda A. Johnson, Ap Business Writer
17 October, 2008
TRENTON, N.J. – Drug giant Pfizer Inc. has reached an $894 million deal to end most of the lawsuits over its two prescription pain relievers, the popular Celebrex and a similar drug, Bextra, no longer on the market.

The world's biggest drugmaker said Friday it has agreements in principle to end more than 90 percent of personal injury lawsuits brought by people claiming the pills caused heart attacks, strokes or other harm.

The settlement includes roughly 7,000 personal injury cases, mainly plaintiffs who took since-withdrawn Bextra, said plaintiff attorney Perry Weitz. He represents nearly 2,000 claimants, about 10 percent of them relatives of people who died.

"It gives Pfizer closure and the claimants their money sooner, rather than later or never at all," Weitz said.

Pfizer hopes to finalize claims covered by the settlement, which now includes up to 92 percent of plaintiffs, by year's end. It also hopes to include many of the remaining claimants in the settlement and will fight any remaining personal injury suits with court motions or at trial, General Counsel Amy Schulman told The Associated Press.

"I don't think either side has an interest in protracting this," Schulman said in an interview.

Weitz said plaintiff lawyers will "have issues" with Pfizer "if their claimants aren't paid before the end of the year."

In early trading, Pfizer shares were down 47 cents, or 2.8 percent, at $16.50.

Schulman said the deal comes after two important court rulings — one by a New York state judge overseeing many of the state-level personal injury cases and the other by a federal judge in San Francisco coordinating pretrial steps in federal lawsuits over the drugs.

"We teed up some pretrial motions for a court ruling on whether there was significantly reliable evidence that would allow an expert to testify as to whether there was an increased risk of heart attack and stroke at the most common dose," 200 milligrams, Schulman said. Both judges ruled that was not the case, she said.

The proposed deal also would end suits by insurers and patients seeking to recover what they spent on Bextra and Celebrex, as well as claims by 33 states and the District of Columbia that Pfizer improperly promoted Bextra.

Out of the total settlement, $745 million will go to settle personal injury cases, $60 million will cover settlements with attorneys general in the 33 states and the District of Columbia, and $89 million will cover consumer fraud class action cases over reimbursement for money spent on the two drugs. Two additional states, Louisiana and Mississippi, still have pending cases regarding Pfizer's promotion of the drugs.

New York-based Pfizer withdrew Bextra from the market in 2005, a year after Merck & Co. withdrew its Vioxx, a similar drug.

The Vioxx withdrawal, which triggered an avalanche of lawsuits against Merck, also raised concerns about the safety of other medicines in the same class, called Cox-2 inhibitors. They were heavily touted by their makers as superior to traditional nonsteroidal anti-inflammatory drugs, or NSAIDs, such as ibuprofen, because they block an enzyme involved in promoting inflammation but — unlike NSAIDs — don't block an enzyme that protects the stomach from bleeding and other side effects.

Other NSAIDs, such as ibuprofen and naproxen, have also been linked to increased heart risks.

Celebrex is the only Cox-2 inhibitor that the Food and Drug Administration has allowed to remain on the U.S. market.

Attorney Christopher Seeger, a member of the plaintiffs steering committee, said he'll "have no problem recommending" the settlement to the roughly 400 clients he represents.

"We're very satisfied with the deal," Seeger said.

Schulman said the company's negotiations with opposing lawyers had been under way for some time but picked up in the late summer.

"Litigation can be distracting, and putting these matters behind us helps our shareholders and, most importantly, patients and doctors," Schulman said.

Weitz noted that it took four or five years to get through trials for less than 20 cases in the massive Vioxx litigation, because the court system can only handle a limited number of cases at a time.

Pfizer will take a pretax charge of $894 million to its third-quarter earnings, which it is scheduled to report on Tuesday.

Merck, based in Whitehouse Station, N.J., has begun paying a $4.85 billion settlement to end about 50,000 lawsuits brought by people claiming Vioxx cause heart attacks, ischemic strokes or death. It still faces other litigation over the former blockbuster arthritis treatment.

Pfizer to Drop Development of Certain Drugs

October 3, 2008 (New York, NY) — Pfizer is getting out of the cholesterol-lowering game to focus on what it perceives to be more lucrative diseases, according to an internal memo obtained by Forbes [1]. And for the most part, the chosen "disease areas" don't include the heart.

In the memo, Martin Mackay, president of Pfizer Global Research & Development (R&D), informed his staff that the company plans to "exit" the fields of atherosclerosis/hyperlipidemia, heart failure, obesity, and peripheral arterial disease.

Instead, the company, whose cholesterol-lowering drug atorvastatin (Lipitor) is the world's top-selling drug, says it is turning its attention and R&D dollars to cancer, diabetes, Alzheimer's, pain remedies, and mental health as its "higher-priority areas."

The news comes in the wake of the flop of Pfizer's hoped-for new flagship, torcetrapib, a CETP inhibitor that was widely predicted to be the company's next blockbuster drug. While CV drugs have been the major moneymakers for Pfizer in recent years, those days are drawing to a close. In addition to Lipitor, which will lose patent protection in 2011, Pfizer's other major player in the CV drug arena is Norvasc (amlodipine), which came off patent in 2007.

Among the lower-priority "disease areas" where the company says it will continue working are thrombosis and transplant, the memo notes.

Contacted by heartwire, a handful of leaders for some of the major Pfizer-sponsored trials in cardiovascular disease over the past decade declined to comment on the company's announcement or speculate on what it might mean to the field of CV drug development--with one exception. Dr John Kastelein (Academic Medical Center, Amsterdam, the Netherlands), who was an investigator in the Pfizer-sponsored ASAP, TNT, and IDEAL trials, called Pfizer "a real powerhouse" in the CV drug arena.

"I kind of knew this was coming, but when you see it in print, it still hits hard," he told heartwire. "I think this is very, very significant both for the company itself and for the whole field of CV drug development. Pfizer had truly excellent people in the development arm of their company for CV and metabolic drugs, and they've contributed to this whole notion that you need more robust LDL lowering and that that's better than mild LDL lowering, which has become one of the axioms of CV prevention. And if they're stepping out now, that not only signifies their own problems, but it also signifies the problems in CV drug development, and how incredibly difficult and costly it has become to bring new drugs forward. And that's not good for patients."

Kastelein predicts that drug companies, having "lost faith" somewhat in HDL-raising therapies, will need to look more closely at anti-inflammatory drugs in the setting of coronary artery disease. "But there, the problem is, if you have no biomarkers whatsoever to do even dose-finding studies, you need to move from relatively small phase 2 trials to incredibly large, hard-outcome studies, which is taking quite a risk," he said. And that, at least for Pfizer, is too much risk.

"Everyone, not just Pfizer, is realizing that the days of the really big blockbuster drugs are over. And what is going to replace that are drugs in a class that are 10 times or 100 times more difficult to develop, so the risks are much higher. And these days, after Avandia and ezetimibe, everything is about safety. This means the FDA is forced, by public and colleague pressure, to demand even larger databases before drugs are going to market, which is of course making it more expensive. It's a cycle that's very hard to break."

Calls to Pfizer were not returned before this story was published.
