A study performed at Edinburgh University, Scotland has shown that aspirin may do more harm to your health than good.

The research at the university in Scotland was to assess the effects of taking aspirin on a daily basis where no prior or existing medical conditions would merit its prescription. The researchers monitored 3,350 patients aged between 50–75, who were thought to be at risk of heart disease, but did not show any significant symptoms at the start of the study. Over an eight-year time period, 181 of those people taking aspirin had heart attacks or strokes.

More than 3,000 men aged 50–75 were randomly assigned to receive a daily dose of aspirin or a placebo pill and were watched over the eight year time period. There were 34 major bleeds in people taking aspirin, or 2%, in comparison to 1.2% of those who took the placebo. The Aspirin for Asymptomatic Atherosclerosis (AAA) have found that the routine use of aspirin does not prevent vascular disease or conditions and the use of it “could not be supported.”

Peter Weissberg, a professor at the British Heart Foundation, the company which was partly responsible in funding for the trials said, “we know that patients with symptoms of artery disease, such as angina, heart attack or stroke, can reduce their risk of further problems by taking a small dose of aspirin each day. The findings of this study agree with our current advice that people who do not have symptomatic or diagnosed artery or heart disease should not take aspirin, because the risks of bleeding may outweigh the benefits. Because it’s been around for a long time, people think, ‘It must be safe and it can’t do any harm’. They are taking it ‘just in case’ but it’s much more dangerous than some other drugs that people get concerned about, like statins.”

Professor Gerry Fowkes presented the research from the University of Edinburgh at the European Society of Cardiology congress in Barcelona, Spain, which was attended by more than 30,000 heart specialists.

“Our research suggests that aspirin should not be prescribed to the general population, although it does have benefits for people with established heart disease or other conditions,” stated Fowkes.

Cars drove home the big prize last night, from the 34th Annual Annie Awards. The animation industry’s highest honor, ASIFA-Hollywood’s Annies recognise contributions to animation, writing, directing, storyboarding, voice acting, composing, and much more.

As mentioned, Pixar took home the big prize last night, after facing stiff competition from four other Happy Feet, Monster House, Open Season, and Over the Hedge.

But the biggest winner of the night didn’t get a “Best Animated Feature” nod at all. Flushed Away won five feature animation categories including Animated Effects (Scott Cegielski), Character Animation (Gabe Hordos), Production Design (Pierre-Olivier Vincent), Voice Acting (Sir Ian McKellan as Toad), Writing (Dick Clement, Ian La Frenais, Chris Lloyd, Joe Keenan, and Will Davies).

Over The Hedge won awards for Directing (Tim Johnson and Karey Kirkpatrick), Storyboarding (Gary Graham), and Character Design (Nicolas Marlet).

Of little surprise, Randy Newman won an Annie for Cars in the “Music in an Animated Feature Production” category. Newman has won many Oscars for his movie music, and has a nomination this year for the song “Our Town”. Newman didn’t attend the Annies, instead picking up a Grammy for “Best Song Written For Motion Picture, Television Or Other Visual Media”.

DisneyToon Studios’ Bambi II won “Best Home Entertainment Production”, while “Best Animated Short Subject” went to Blue Sky Studios’ No Time For Nuts, which is based on Ice Age.

“Best Animated Video Game” went to Flushed Away The Game, while a United Airlines ad named “Dragon” won a “Best Animated Television Commercial” Annie for DUCK Studios.

The University of Toronto SciNet Consortium went online yesterday with the IBM System x iDataPlex Supercomputer.

U of T’s IBM System x is now the fastest computer outside of the United States, the largest Intel processor based IBM installation internationally and the twelfth most powerful globally. It will be used for a wide variety of operations, such as analysing climate change models, aerospace, astrophysics, genetics, bioinformatics, chemical physics, medical imaging research and other highly calculation-intensive tasks.

The C$50 million dollar supercomputer can perform 300 trillion calculations per second and uses the equivalent amount of energy which would power 4,000 homes. The supercomputer will be cooled by outdoor winter air assisted by a water based cooling system during warmer summer months.

The computer will provide computations for the Large Hadron Collider (LHC) that started preliminary experiments on September 10, 2008 at CERN in Geneva, Switzerland. The LHC will produce cataclysmic collisions that will mimic the conditions that existed shortly after the beginning of time. The IBM System x’s 30,240 Intel 5500 series 2.53 GHz processor cores — arranged in 45 file-like stacks — will examine the results of the particle collisions.

Tuesday, March 29, 2005A team of Australian surgeons yesterday reattached both hands and one foot to 10-year-old Perth boy, Terry Vo, after a brick wall which collapsed during a game of basketball fell on him, severing the limbs. The wall gave way while Terry performed a slam-dunk, during a game at a friend’s birthday party.

The boy was today awake and smiling, still in some pain but in good spirits and expected to make a full recovery, according to plastic surgeon, Mr Robert Love.

“What we have is parts that are very much alive so the reattached limbs are certainly pink, well perfused and are indeed moving,” Mr Love told reporters today.

“The fact that he is moving his fingers, and of course when he wakes up he will move both fingers and toes, is not a surprise,” Mr Love had said yesterday.

“The question is more the sensory return that he will get in the hand itself and the fine movements he will have in the fingers and the toes, and that will come with time, hopefully. We will assess that over the next 18 months to two years.

“I’m sure that he’ll enjoy a game of basketball in the future.”

The weight and force of the collapse, and the sharp brick edges, resulted in the three limbs being cut through about 7cm above the wrists and ankle.

Terry’s father Tan said of his only child, the injuries were terrible, “I was scared to look at him, a horrible thing.”

The hands and foot were placed in an ice-filled Esky and rushed to hospital with the boy, where three teams of medical experts were assembled, and he was given a blood transfusion after experiencing massive blood loss. Eight hours of complex micro-surgery on Saturday night were followed by a further two hours of skin grafts yesterday.

“What he will lose because it was such a large zone of traumatised skin and muscle and so on, he will lose some of the skin so he’ll certainly require lots of further surgery regardless of whether the skin survives,” said Mr Love said today.

The boy was kept unconscious under anaesthetic between the two procedures. In an interview yesterday, Mr Love explained why:

“He could have actually been woken up the next day. Because we were intending to take him back to theatre for a second look, to look at the traumatised skin flaps, to close more of his wounds and to do split skin grafting, it was felt the best thing to do would be to keep him stable and to keep him anaesthetised.”

Professor Wayne Morrison, director of the respected Bernard O’Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne’s St Vincent’s Hospital, said he believed the operation to be a world first.

Several mainstream news outlets have misstated and overstated a possible link between cellular phone use and decreased fertility in men. A single experiment, which has not yet been published in any peer reviewed journal or replicated by other scientists, observed an average decrease in sperm motility and an increase in free radicals among laboratory sperm samples that were exposed to radiation similar to the radiation produced by cellular phone use.

Dr. Ashok Agarwal of the Cleveland Clinic estimates the overall health impact of cellular phones as “very safe” and reassured a Cable News Network reporter that the research was too premature to advise lifestyle changes for the public. “Our study has not provided proof that you should stop putting cell phones in your pocket. There are many things that need to be proven before we get to that stage.” He noted that his own cell phone was in his trouser pocket while he was giving the interview. Dr. Agarwal is the lead researcher for the study and Director of the Center for Reproductive Medicine at the Cleveland Clinic.

Cell phone industry spokesman Joe Farren agreed with Dr. Agarwal’s assessment about the devices’ overall safety: “The weight of the published scientific evidence, in addition to the opinion of global health organizations, shows that there is no link between wireless usage and adverse health effects.”

The controlled experiment used sperm samples from thirty-two donors: twenty-three healthy men and nine men who had fertility problems. Sperm were then exposed to radiation for one hour at 850 megahertz, the most common frequency for cell phones in the United States. Dr. Agarwal’s study raises a possible concern that cell phones kept on belts or trouser pockets and used in conjunction with wireless bluetooth earpieces “could cause harmful effects due to the proximity of the phones and the exposure that they are causing to the gonads.” He also noted that follow-up research is needed to determine whether the body’s skin and other tissue affords protection from the potential damage.

Several news sources ran misleading reports that overstated the risk.

The Los Angeles Times asserted a fallacious causal relationship that Dr. Agarwhal had not drawn and ignored his opinions that cellular phones are safe and no change in phone use is necessary. Instead, the piece opened by ordering men to stop keeping cell phones in their pockets:

“Attention male cellphone users of reproductive age: Take that phone out of your pocket. Information published today suggests that the radio-frequency energy released by cellphones decreases sperm quality in men.”

Ciol News ran a similar account:

“Beware men! Do you have the habit of keeping your mobile phone in the pockets of your trousers while talking on hand-free? Or do clip the mobile to your belt while talking? If so you are doing that at the cost of your fertility, warns a recent study.”

Mobile Magazine went a step further, also alluding to previous media exaggerations about cellular phone dangers:

“Oh no! It seems that mobile phones are getting even more problematic than ever. After getting linked to everything from migraines to cancer, it seems that the radiation from cell phones is now being connected to stupid sperm. Yes, I’m talking about the little swimmers that lead into a conversation about the birds and the bees.”

Mobile Magazine also ended in a misleading manner with “I wonder if it’s healthier to put your phone in your shirt pocket instead,” failing to mention that Dr. Agarwal had addressed that concern and had called it an unnecessary precaution.

Not all news sources overplayed the findings. CNN and United Press International ran balanced reports that did not suggest dangers or precautions beyond the lead researcher’s conclusions.
