ST. PAUL, Minn. – People taking cholesterol-lowering drugs such as atorvastatin after a stroke may be at an increased risk of hemorrhagic stroke, or bleeding in the brain, a risk not found in patients taking statins who have never had a stroke. But researchers caution the risk must be balanced against the much larger overall benefit of the statin in reducing the total risk of a second stroke and other cardiovascular events when making treatment decisions. The research is published in the December 12, 2007, online issue of Neurology®, the medical journal of the American Academy of Neurology.

For the study, researchers conducted a secondary analysis of the results of the Stroke Prevention with Aggressive Reduction in Cholesterol Levels (SPARCL) clinical trial. The trial enrolled 4,731 people who were within one to six months of having had a stroke or transient ischemic attack, or mini-stroke, and with no history of heart disease. Half of the participants received atorvastatin and half received a placebo. The participants were then followed for an average of four and a half years.

Overall, treatment was associated with a 16-percent reduction in total stroke, the study’s primary endpoint, as well as significant reductions in coronary heart events. However, secondary analysis found that the overall reduction in stroke included an increase in the risk of brain hemorrhage. Of those people randomized to atorvastatin, the study found 2.3 percent experienced a hemorrhagic stroke during the study compared to 1.4 percent of those taking placebo. The study also found there was a 21-percent reduction in ischemic stroke, a more common type of stroke involving a block in the blood supply to the brain, among people taking atorvastatin.

Other factors were also found to increase the risk of brain hemorrhage. For example, those who had experienced a hemorrhagic stroke prior to the study were more than five times as likely to suffer a second stroke of this kind. Men were also nearly twice as likely as women to suffer a hemorrhagic stroke. People with severe high blood pressure at their last doctor’s visit prior to the hemorrhagic stroke had over six times the risk of those with normal blood pressure.

“Although treatment of patients with a stroke or transient ischemic attack was clearly associated with an overall reduction in a second stroke, hemorrhagic stroke was more frequent in people treated with atorvastatin, in those with a prior hemorrhagic stroke, in men and in those with uncontrolled hypertension,” according to study author Larry B. Goldstein, MD, with Duke University Medical Center in Durham, North Carolina, and Fellow of the American Academy of Neurology. “This risk of hemorrhagic stroke also increased with age.”

“Treatment with atorvastatin did not disproportionately increase the frequency of brain hemorrhage associated with these other factors. The risk of hemorrhage in patients who have had a transient ischemic attack or stroke must be balanced against the benefits of cholesterol-lowering drugs in reducing the overall risk of a second stroke, as well as other cardiovascular events,” said Goldstein.

The SPARCL trial was funded by Pfizer, the maker of atorvastatin.

The American Academy of Neurology, an association of more than 20,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson disease, and multiple sclerosis.

FOOD FOR SKINNY KIDS – A STORY WHICH NEEDS TO CIRCULATE FOREVER

by Jeanne Hambleton © 2007
NFA Leader Against Pain – Advocate

Maybe I should mention that you just might need some kleenex tissues before you start this story but please read it anyway, if only in the spirit of Goodwill to All Children. The men are big enough to look after themselves.

As folks in the UK were getting ready this morning to do some Christmas shopping an email arrived on my desktop with a warning, which said,  “This email needs to circulate forever.”

How could I pass up this invitation to inquire within? The email also stated, “This is a real eye opener. A real tear jerker No prerequisites (commitments).  Simply, because everyone should be reminded.“

This was sent to me by a lady from Montevideo, Uruguay called Marta. Where the pictures, shown in the email, were taken, it does not say, but I am sure it conveys a worldwide message, especially within the African continent.

Picture 1. shows European students sat at computers working, with the caption, “Does studying annoy you?”
Picture 2. reveals children, possibly from Africa, without shoes, sat on a bench and drawing their lessons in the dirt with their fingers. The caption says, “ Not them!”

Picture 3. is a happy family picture of a father with his daughter enjoying a beef burger roll with the words, “Hate veggies?”
Picture 4. is a picture of a long line of native mothers and starved children, clothed, in rags and waiting in line with a bowl for some food handouts. This caption says, “They starve from hunger!”


By fmsglobalnews

Picture 5. reveals the back view of a jolly obese child having fun, with a caption which reads, “On a diet?”
Picture 6. gives a close-up of a painfully thin starved child with a tape measure around the child’s matchstick thin arm. The caption referring to diet says, “They die from it!” Or the lack of any kind of diet.

Picture 7. shows a baby being cuddled by a parent revealing the lovely cuddly cheeks of a child’s bottom. This reads, “Does your parent’s care tire you?”
Picture 8. shows a sibling cuddling a child with the last bone in the baby’s spine clearly visible as she rests in sister’s arms for comfort. This caption tells us these children have no parents to grow tired of. “They don’t have any!”


By fmsglobalnews

Picture 9. reveals youngsters sat at a games console and states, “Bored with the same game?”
Picture 10. Shows a young unclothed child playing in the dirt with a bit of stick, next to the human skull of someone who had probably died from starvation. The caption reads, “They have no option!”

Picture 11. shows a smart new trainer with a caption which reads, “Someone got you Adidas instead of Nike?”
Picture 12. pictures the feet of a child with half of a plastic bottle cut to make the sole of a pair of sandals. The picture clearly reveals the screw top of the plastic bottle on the footwear, which is tied onto the foot with rag. This caption states, “They only have one brand?” Maybe it is cola?????

Picture 13. is of a sweet little girl in clean pyjamas snuggled up in her cosy bed. This caption reads, “Aren’t you thankful for a bed to sleep in?”
Picture 14. The final contrast picture shows a child laying in the dirt, half covered with a piece of old rag, trying to sleep, with a caption that reads, “They’d wish not to wake up!”


By fmsglobalnews

The closing slide asks, “Are you still complaining? Observe around you and be thankful for all that you have in this transitory lifetime…. We are fortunate to have much more than what we need to be content. Let us try not to feed this endless cycle of consumerism and immortality in which this ‘modern and advanced’ society forgets and ignores the other two thirds of our brothers and sisters. Send this information without any obligation or expectation in receiving good luck. Don’t keep it! Send it and it won’t be in vain. Let us complain less and give more!”

I imagine you feel as I do. I work hard for my dollar and I do not believe in sharing my hard earned cash with large charities who have magnificent offices, managing directors, hundreds of paid staff and devote just a fraction of their donations to their ‘good’ works. You can call me the woman with the long pockets if you like, but I want to know my money is going where it will doing some good and helping those would really need it. How to be confident about that I am not sure? In true Scorpion fashion I hate to be misled or deceived.

Quite how we can help these starving children is the burning question. I have had masses of appeals for all sorts of charities drop on my doormat in recent weeks. At least these ends up in the local hospice waste paper recycling skip and help them a little along with our papers and magazines. I looked on the Internet at our UK BBC Children in Need but could not see children in a similar situation.

SAVE THE CHILDREN
The UK Save the Children organisation has produced a Christmas shopping catalogue, on line, so should you decide to buy Christmas gifts from them you are indirectly donating while shopping, just how much remains to be seen! Perhaps this might be more acceptable – buying and giving at the same time. It is easy to look at this site to see the work they are doing and possibly shop with them. Every Christmas I seem to receive more and more cards printed by charities and sent by to me by friends.

http://www.savethechildrenshop.co.uk/home

However I should mention that if you telephone their UK number – 0844 557 5425 – instead of ordering on line, it could cost you 40p a minute as you give your details and make your mind up. Some of that money will be going to the charity.

Our doctors’ surgery is using this 0844 prefix number and getting a rake off which is a bit vexing considering how much our GPs are reported to be earning – but that is another story.

No – I am not a sales rep for any charity – just a concerned parent. No, this is not a commercial for children’s charities – it is a wake up call.

The American Save the Children website also appears to have a programme for under privileged children in developing countries, who are suffering from hunger and poverty. It seems you can also purchase festive gifts from them indirectly helping the cause.

http://www.savethechildren.org/

What you decide to do is between you and your conscience. I would however like to leave you with these thoughts.

These pictures and words certainly do bring you down to earth especially when you consider the wastage by governments the world over.  I am just sorry I could not reproduce the pictures but I am sure you know the kind of scenes I mean – you must have seen them on TV from time to time. Send me your email address with the request for these pictures if you would like them forwarding.

Just consider the money all of the worldwide governments squander… it is time someone added the total figure and gave us some home truths.

These starving children, if they live, may be our next generation – our future leaders. Do you think if they survive they could be future terrorists? I am sure they will have a grudge against the world – surely they will feel the world owes them a living. This is all very sad and really makes you think. Whatever happened to the innocence of childhood?  

Just imagine what we spend on consumerism not to mention what we will spend on our own children this Christmas 2007. I wonder what our children would think if we put these pictures under the Christmas tree on Dec.25 instead of a new bike, a new game toy and all the other things children of our modern world expect to receive from their parents aka Father Christmas?

What would it be like if children all over the world went without just one toy from their festive gifts in aid of the starving and poverty stricken children. It would take a lot of organizing to gather in that money and it is a huge task but it could be done – all it needs is a good website supported by reliable well known people…. even if it took until Easter to collect the money – the children would still be starving.

Where are you Bob Geldorf? Can you help us with this? Does someone know his email address? My mind is boggling at the power of the people…… How about Skinny Kids for a campaign title – that rather sums it up!

Just a thought – maybe if that £5 we would be spending on a nonsense stocking gift for someone who has everything, was replaced with a warm note telling them Christmas is for children – starving children in particular – and they would be receiving his gift money with a tax gift aid. Sorry but this has been sent to starving “Skinny Kids” who have nothing.

I would hope we would get a really warm hug for this initiative. This friend really did not need an air freshener toy for his car or a key ring. If we did not get a big hug that receiver is a Christmas Meanie…. Take it from me. We will cross him off our Christmas list in future – so there.

Sorry to be a party pooper – but someone has to do it.  I will make up for it and send you some happier stories in the near future.

Take care. Jeanne.

Scientists propose explanation for out-of-body experiences

This release is available in French, Spanish and Japanese.

Using virtual reality goggles to mix up the sensory signals reaching the brain, scientists have induced out-of-body-like experiences in healthy people, suggesting a scientific explanation for a phenomenon often thought to be a figment of the imagination.

The sight of their bodies located somewhere else — thanks to the goggles — plus the feel of their real bodies being touched simultaneously made volunteers sense that they had moved outside of their physical bodies, according to a pair of studies in the 24 August 2007 issue of the journal Science, published by AAAS, the nonprofit science society.

A disconnect between the brain circuits that process both these types of sensory information may thus be responsible for some out-of-body experiences, the researchers say.

Out-of-body experiences, which generally involve the feeling of disembodiment and seeing one’s own body from a location outside the body, can occur in part through drug use, epileptic seizures and other types of brain disturbances.

By projecting a person’s awareness into a virtual body, the techniques used in these studies may be useful for training people to do delicate “teleoperating” tasks, such as performing surgeries remotely. The findings may also remove some of the stigma that patients with neurological disorders may feel about having these experiences, which are frequently attributed to an active imagination or some sort of paranormal phenomenon.

The studies also help solve the age-old question of how we perceive our own bodies.

“I’m interested in why we feel that our selves are inside our bodies — why we have an ‘in-body experience,’ if you like. This has been discussed for centuries in philosophy, but it’s hard to tackle experimentally,” said Science Brevium author Henrik Ehrsson of University College London, in London, and the Karolinska Institute in Stockholm.

Both Ehrsson and another research team, led by Olaf Blanke of the Ecole Polytechique Fédérale de Lausanne (EPFL) and the University Hospital in Geneva, Switzerland, used video cameras and virtual reality goggles to show volunteers images of their own bodies from the perspective of someone behind them. The researchers also touched the volunteers’ bodies, both physically and virtually.

The volunteers in Ehrsson’s study viewed images recorded by the cameras through their headsets. In Blanke and colleagues’ study, the video was converted into holograph-like computer simulations.

Ehrsson had the volunteers watch a plastic rod moving toward a location just below the cameras while their real chests were simultaneously touched in the corresponding spot. Questionnaire responses afterwards indicated that the volunteers felt they were located back where the cameras were placed, watching a dummy or a body that belonged to someone else.

“This experiment suggests that the first-person visual perspective is critically important for the in-body experience. In other words, we feel that our self is located where the eyes are,” Ehrsson said.

Ehrsson also had the volunteers watch a hammer swing down to a point below the camera, as though it were going to “hurt” an unseen portion of the virtual body. Measurements of skin conductance, which reflects emotional responses such as fear, indicated that the volunteers sensed their “selves” had left their physical bodies and moved to the virtual bodies.

Blanke’s team used a similar setup to create out-of-body-like experiences (which they cautioned lacked some aspects of full-blown out-of-body experiences).

After the virtual reality exercise, a researcher would blindfold the volunteers and guide them backward. When the volunteers were asked to return to their original position, they tended to drift toward where they had seen their virtual bodies standing.

Both studies conclude that “multisensory conflict” is a key mechanism underlying out-of-body experiences.

“Brain dysfunctions that interfere with interpreting sensory signals may be responsible for some clinical cases of out-of-body experiences,” Ehrsson said. “Though, whether all out-of-body experiences arise from the same causes is still an open question.”

Bodily self-consciousness may also involve a cognitive dimension – the ability to distinguish between one’s own body and other objects – in addition to sensory signals, Blanke and his coauthors propose.

Supporting this idea, Blanke’s team reports that when the volunteers viewed a human-sized block instead of an image of a human body, they successfully returned to their original standing place, indicating that no out-of-body-like illusion had occurred.

“Full-body consciousness seems to require not just the ‘bottom up’ process of correlating sensory information but also the ‘top down’ knowledge about human bodies,” Blanke said.

Some of the out-of-body experiences that have previously eluded scientific explanation may be related to distorted “full-body perception,” according to Blanke. Virtual reality systems may provide further answers.

“We have decades of intense research on visual perception, but not very much yet on body perception. But that may change, now virtual reality offers a way to manipulate full body perception more systematically and probe out-of-body experiences and bodily self consciousness in a new way,” Blanke said.

Quantum light beams good for fast technology

Australian and French scientists have made another breakthrough in the technology that will drive next generation computers and teleportation.

The researchers have successfully superposed light beams, which produces a state that appears to be both on and off at once.

Light beams that are simultaneously on and off are vital for the next-generation super computers which should be faster than current computers based on bits, that are either on or off.

Previously, only smaller light particles had been superposed and the group has also proved a quantum physics theory known as Schrödinger’s cat.

This theory, named after an Austrian physicist Erwin Schrödinger, proposed that a large object such as a cat could be simultaneously alive and dead.

Researchers from The University of Queensland and University of Paris South have published the latest breakthrough in the international journal NATURE.

UQ Centre for Quantum Computer Technology researcher Dr Hyunseok Jeong devised the scheme to generate and superpose the beams which was tested and proved by his French collaborators.

Dr Jeong said his group used special lasers, crystals, photon detectors, half-mirrors and other optical devices to generate and measure the superposition of light beams.

“It has been known to be extremely hard to generate Schrödinger cat states, particularly with traveling light,” Dr Jeong said.

“Even though one could generate such Schrodinger cat states, it would be extremely hard to observe them because in a very short time, they would be reduced to either alive or dead states.”

He said his group’s research findings would help speed up the development of quantum information technologies such as quantum computers, quantum cryptography and quantum teleportation.

“Using Schrödinger cat states, quantum teleportation may be performed with nearly 100 percent success probability.”
