A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

At least 10 pets, 9 cats and 1 dog have died as a result of eating contaminated pet food, says the United States Food and Drug Administration, or FDA. The contamination caused cats and dogs to both go into kidney failure.

At least 51 brands of cat food and 40 brands of dog food have been recalled. The manufacturer of the food is Menu Foods, which is based in Mississauga, Ontario in Canada. The brands include: Iams, Nutro, and Eukanuba pet foods. Nestle, Purina PetCare Co., Procter & Gamble and Hill’s Pet Nutrition Inc. are voluntarily recalling their pet foods as a precaution. The FDA says that only wet food has been reported to have caused the deaths. The food was sold between December of 2006 and March 3 of 2007. The recall includes pouches and cans of wet food that total over 60 million.

“We are still trying to find out what the true picture is out there of animals. We’re talking about 1 percent of the pet food [supply] and it’s really just impossible to extrapolate at this point,” reported the FDA’s head veterinarian, Stephen F. Sundlof.

The manufacturer is currently performing tests to determine what might have caused the contamination, but so far, the source has not been identified.

“We’re testing and testing, but we can’t identify the problem in the product,” said Sarah Tuite, a spokeswoman for Menu Foods.

Anywhere from 40 to 50 cats and dogs were fed the contaminated food during testing by Menu Foods, and at least seven of those animals died. The species or how many cats or dogs died during testing is not known.

The FDA says that the possible cause of the contamination could be from heavy metals, lead or fungi inside wheat gluten which is used in pet foods as a “filler.”

A complete list of the products recalled can be found here: Menu Foods Recall List. Pet owners are urged to stop using any and all food on that list that may still be in their home. Owners are also asked to seek immediate veterinarian attention if the pets are suspected of eating the food.

The recall could cost over 30 million USD.

A grassroots movement known as Restore the Fourth, dedicated to the protection of the 4th Amendment to the US Constitution, are to hold protests countrywide on July 4. The planned protests come in the wake of information about NSA surveillance leaked last month, notably the PRISM surveillance program and the collection of Verizon phone records. Wikinews interviewed Jett, a national organizer from this recently created movement.

((Wikinews)) First of all, could you explain what Restore the Fourth is all about?

Jett: At its core, RestoreTheFourth is about protecting citizens’ constitutional rights. Specifically, we’re dedicated to bringing awareness and action to the expanding overreach and elimination of the 4th Amendment to the US Constitution.

((WN)) What is your role at Restore the Fourth?

Jett: My job at RestoreTheFourth could be summarized as ‘project coordinator’. Every person who wants to help can help in a tremendous way. I simply make sure that their skills get used in a way that would be most beneficial to the movement: web development, public relations, etc. I also field questions from the press and promote knowledge of our cause.

((WN)) What are your plans for direct action, outreach, etc.?

Jett: Our press release includes a list of ‘demands’ for what we want to see in order to restore our privacy rights, including reform of the PATRIOT Act and increased accountability for public officials. In the very short term, these protests and demonstrations bring awareness to the issue, something that’s really important in enacting reform. In the long term, however, we expect to create a legal organization dedicated to restoring these rights inherent to every American. By partnering with various other organizations that share our moral values, we can further these goals.

On July 4, we will have over 100 protests in all 50 states, showing that the citizens of America are truly serious about protecting their rights.

((WN)) By what means do you hope to achieve such change?

Jett: This movement started only a few weeks ago, and since then we’ve experienced exponential growth and progress. Since the movement is still very young, plans diverge in the long term on what we hope to achieve. Personally, I’d like to see a combination of legislative and litigative action (something like what the ACLU does), and others want to see further plans of action. With organizations such as the BORDC, stopwatching.us and the EFF behind us, I feel that we can achieve all of this and much more.

((WN)) Is the movement US-only or will it extend to other jurisdictions as well? Do you think it would be fair for the US to spy on non-citizens?

Jett: I believe that rights are inherent to all humans, not only United States citizens. In the long term I’d certainly like to see people of all nations protected from the slow elimination of privacy that we’re all experiencing.

((WN)) What do you think about Edward Snowden’s whistleblowing?

Jett: I think that too much attention is being given to his personality instead of what he fought for. He’s being treated as a ‘martyr’ of sorts. It seems to distract from what he truly believed in — transparency for the government and inherent privacy for all Americans.

((WN)) What do you think about his future, given the legal grey zone in which he currently is?

Jett: Hard to say. He may be captured by any number of agencies, or he may live a free man. Whatever happens, he has the eyes of millions of people on him, all of whom will yell very loudly if anything occurs.

((WN)) Thank you very much for your time.

Jett: Thanks for the opportunity.

In findings published on Wednesday in Science Advances, researchers from the Georgia Institute of Technology (GT) and University of South Carolina Beaufort, both in the United States, reported warming seas appear to decrease the efficacy of the chemical compounds that corals release into the water to defend themselves from bacteria and encroaching seaweed, but these losses may be mitigated if there are large numbers of hungry fish around.

The research was led by Mark Hay, a marine ecologist and Regents Professor at GT, who said “There is a lot of argument now about whether local management can help in the face of global stresses — whether what a Fijian village does matters when people in London and Los Angeles burn fossil fuels to drive to work”. Hay added, “Our work indicates that local management provides a degree of insurance against global stresses, but there are likely higher temperatures that render the insurance ineffective.”

The researchers examined three types of coral in reefs off the coast of Fiji, Acropora millepora, Porites cylindrica, and Pocillopora damicornis. Some of these reefs were in areas where fishing was prohibited and some were not. The researchers found when fish were plentiful, they would eat algae and seaweed off the corals, which appeared to leave them more resistant to the bacterium Vibrio coralliilyticus, a bacterium associated with bleaching.

The researchers suggested the algae, like warming temperatures, might render the corals’ chemical defenses less effective, and the fish were protecting the coral by removing the algae. They reported, “Macroalgae are suggested to disrupt coral microbiomes via transfer of allelochemicals or microbes or release of dissolved organic carbon that affects microbial growth”.

P. cyclindrica and P. damicornis are known to be function under conditions that damage other corals and A. millepora is not.

Each reef-building coral unit is a collection of polyps living in symbiotic partnership with zooxanthellae algae. The polyp, a cnidarian as are jellyfish, provides stinging protection and secretes a calcium shell, and the algae performs photosynthesis, produces oxygen and gives the coral its color. Changing ocean environments have led to a phenomenon called coral bleaching when warmer waters cause the cnidarian to expel the algae from its body, which turns the coral reefs white. This does not kill the cnidarian partner but does leave it badly weakened and vulnerable to disease.

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.

The 1999 and 2000 year model Honda Civic SiR tops the list of Canada’s most stolen cars.

Consumer popularity also assures the cars will be popular with thieves. Its the second year in a row the Honda SiR has topped the list.

Rick Dubin Vice President of Investigations for the Insurance Bureau of Canada said “The Civics are easy targets.”

Dubin said that once stolen, the cars are most often sold to “chop shops” where thieves completely dismantle the vehicles. The automobile’s individual parts are worth more than the entire car.

The sheer numbers of the cars and their lack of theft deterrent systems make them thieves’ preferred choices.

1999 and 2000 Honda Civics do not come with an electronic immobilizer, however all Hondas from 2001 and onward are equipped with an immobilizer. Immobilizers will be mandatory on all new cars sold beginning September 2007. The devices enable an engine computer to recognize an electronic code in the key. If the code in the key and the engine don’t match exactly, the vehicle can’t be started.

In third place was the 2004 Subaru Impreza, while the 1999 Acura Integra came in fourth, with the 1994 Honda Civic rounding out the top five.

In sixth place, the 1998 Acura Integra, and the 1993 Dodge Shadow completed seventh.

When asked why early model vehicles are selected, he said that, “auto thieves continue to find it easier to steal older vehicles lacking an IBC-approved immobilizer. We’ve seen this trend developing for several years, and these results confirm it.”

Another Honda automobile, the 1996 year model Civic filled eighth place, with the 2000 German Audi TT Quattro in ninth.

The American 1996 Chevrolet/GMC Blazer rounded out the top ten.

None of the above cars had an electronic immobilizer.
