Gastric bypass surgery performed by remote control

Sunday, August 21, 2005

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.

San Fernando, Chile — Ten students from the Liceo María Luisa Bombal of Rancagua, O’Higgins Region were detained by the local police yesterday. Following their release, the students told the media they were required to remove their clothes at the police station.

The students, seven men and three women, took control of the building of the school early yesterday morning in response to the long delay in re-construction of the liceo, following the earthquake of 2010. At around 08:00 local time (1200 UTC), Leonardo Fuentes, general secretary of the Municipal Educational Corporation of Rancagua, authorized the police to clear out the students.

Student leader Jennifer Olivares told Diario VI Región the police “stripped off [their] clothes” ^{((es))Spanish language: ?Al llegar a la comisaría nos desnudaron.} upon their arrival at the police station, Comisaría de Rancagua, something which Lieutenant Colonel of Carabineros Iván Guajardo did not deny. However, police stated the students will be charged by the public prosecutor with robbing food from the school. “It’s a bit illogical that they stripped off our clothes, with the knowledge that there were minors and without [us] being delinquents, but students who took the school peacefully” ^{((es))Spanish language: ?Es un poco ilógico que nos desnuden habiendo menores de edad y no siendo delincuentes, sino estudiantes que estábamos en una toma que había sido pacífica}, said Olivares. Ignacio Muñoz, former leader of the occupation of the Liceo María Luisa Bombal, told El Rancahuaso “the Mayor [Eduardo Soto] promised to begin the reconstruction works last summer, and it’s August already and they don’t even begin to take the debris outside” ^{((es))Spanish language: ?El alcalde se comprometió a comenzar los trabajos de reconstrucción durante el verano de este año, y ya estamos en agosto y aún no comienzan ni moviendo los escombros del interior}. Education Regional Secretary (Seremi de Educación) Pedro Larraín said the government “does not share” ^{((es))Spanish language: ?No compartimos las tomas} such actions, “because they harm education” ^{((es))Spanish language: ?porque perjudican a la educación}.

The Region of Libertador General Bernardo O’Higgins was one of the first in 2012 to resuscitate the previous year’s student protests, more specifically at the Liceo Industrial de San Fernando, which was taken control by the students in late July, and which as of yesterday was still taken. The students of the Liceo Industrial were particularly affected, after the president of the school’s centro de alumnos Guillermo Horta Farías was stabbed outside the educational establishment on July 31; his fellow schoolmates subsequently organized a march in his honour in Rancagua, on August 8. As of August 11, eight high schools have been taken control of by students, in response to the government’s failure to satisfy the secondary and university students’ requests.

What would you tell your grandchildren about 2007 if they asked you about it in, let’s say, 20 year’s time? If the answer to a quiz question was 2007, what would the question be? The year that you first signed on to Facebook? The year Britney Spears and Amy Winehouse fell apart? The year author Kurt Vonnegut or mime Marcel Marceau died, both at 84?

Let’s take a look at some of the international stories of 2007. Links to the original Wikinews articles are in bold.

Officials say that progress is being made in a deal to bail out three United States carmakers. The U.S. government will be holding weekend talks on the plan after two days of Congressional hearings.

Dana Perino, the White House press secretary, stated that discussions with both parties had been “constructive”.

Executives from the three companies – General Motors, Ford, and Chrysler – have pleaded before two Congressional committees, asking for $34 billion in order to stop collapse.

“I’m convinced that by Sunday we will have an agreement that people can understand on this bill,” said Barney Frank, a representative from the state of Massachusetts.

The people of Ghana, a country often shown of as an example of a good democracy in Africa, will vote for a new president and parliament.

The current president, John Kufuor, will resign after serving the maximum of two terms in office. The elections are expected to be close.

The three main contenders for the presidency are: the Nana Akufo Addo from New Patriotic Party, who was the foreign minister under the current president, John Atta Mills running for the National Democratic Congress, and the Convention People’s Party’s candidate, one Paa Kwesi Nduom.

The Archbishop of York, Dr John Sentamu, said that Zimbabwe’s president Robert Mugabe must be forced out of office and face trial for his crimes against humanity.

“The time has come for Robert Mugabe to answer for his crimes against humanity, against his countrymen and women and for justice to be done. The winds of change that once brought hope to Zimbabwe and its neighbours have become a hurricane of destruction, with the outbreak of cholera, destitution, starvation and systemic abuse of power by the state,” said Sentamu.

Sentamu that the power-sharing deal that was signed by Mugabe and the Zimbabwean opposition in September was “now dead”.

Dr Sentamu’s statement comes after a severe cholera outbreak spread in Zimbabwe, and saw 12,545 cases reported and 565 people dead.

A car bomb was used in an attack on the Indian embassy in central Kabul, Afghanistan on Monday morning. The bombing killed 41, and injured at least 141. It is the deadliest attack in Kabul since 2001, when Afghanistan’s Taliban government was ousted by American armed forces.

The attack happened at the gates of the embassy, located in central Kabul, near many other government buildings including the office of the Interior Ministry of Afghanistan. A security office and part of a wall were destroyed, and the blast was large enough to spread debris to surrounding buildings. Ali Hassan Fahimi, whose office is nearby, said shrapnel landed in his office. “It was so strong… our staff were shocked,” he commented.

Many of the victims were Afghans who were lining up for visas to travel to India. Of the casualties, most were civilians. The dead include embassy workers, a defense attache, a senior counselor, two security guards, an Afghan employee and six police officers.

The foreign ministry of Afghanistan said that they “condemn today’s terrorist attack on the embassy of the friendly and brother country of India.” An Afghan government spokesman, Zamari Bashari, suggested that the attack was retaliation for India’s support for reconstruction in Afghanistan. India called the bombing a “cowardly terrorist attack” and said that they would send a delegation to investigate.

Foreign entities voiced similar sentiments. The United Nations envoy Kai Eide said, “I condemn it in the strongest possible terms. In no culture, no country, and no religion is there any excuse or justification for such acts. The total disregard for innocent lives is staggering and those behind this must be held responsible.” The European Union condemned the attack as a “terrorist attack targeting innocent civilians” and the United States said it was a “needless act of violence”. The foreign minister of Pakistan, Shah Mahmood Qureshi, denounced the attack, saying, “Pakistan condemns terrorism in all its forms and manifestations as this menace negates the very essence of human values.”

At the Saskatchewan Association of Rural Municipalities (SARM) conference, a resolution was passed that encourages the Government of Saskatchewan, Canada to place a moratorium on specialty livestock farms raising wild boar. All wild boars that have escaped to roam wild should be killed, according to the resolution.

Agriculture Minister Bob Bjornerud endorses a ban on wild boar farming. The wild boar population is expanding exponentially. There are over 2,000 feral Sus scrofa swine roaming the prairies. Two litters of approximately 12 piglets are sired by each wild boar sow every year. The Saskatchewan Wildlife Federation (SWF) likewise passed a similar resolution at their 79th annual convention to urge the Saskatchewan Government to declare the wild boar as a nuisance species which can be killed on sight.

3% of farmed “wild” boars escape. Cells of wild boars are ravenous creatures killing and eating everything in their path. Horses, cows, and other livestock run from wild boars, breaking through fences in the process.

Ostriches, emus, llamas, alpacas, reindeer, wild boar, and fallow deer were amongst the animals introduced to farms in Saskatchewan during the agricultural diversification program in the late 1970s. Production of wild boars was promoted throughout the 1980s.

According to the Saskatchewan Agriculture and Food 2001 statistics, there were 150 wild boar producers raising approximately 15,000 and 20,000 head. Of these there were about 2,700 sows. On the 2006 Census of Agriculture, 401 farms reported 4,926 boars.

The boar’s red meat is an export commodity to Europe and Asia. The live breeding stock are also sold to trophy hunt ranches. Full blooded wild boar and hybrid crosses are raised.

The mascots of the 2010 Winter Olympics in Vancouver, British Columbia were just announced. Based on mythological characters, they are Miga, Quatchi and Sumi.

Miga, a sea bear who lives in the ocean with her family pod near Tofino, and Quatchi, a young sasquatch, represent the Olympics, while Sumi represents the Paralympics that follow afterward.

A sea bear is a First Nations creature, part killer whale, part Kermode spirit bear. While illustrated as being taller than the other characters, the mascot costume of Quatchi is the same height as the other two characters.

The third mascot, Sumi, an animal-guardian spirit, is a Thunderbird that wears the hat of an orca. Sumi will be the mascot of the Paralympics.

In 2004, the Times Colonist suggested a marmot might be a good mascot, except for their winter hibernation. The organizers still chose one, named Mukmuk, as their “virtual only” counterpart.

After the Olympic logo design was leaked the day before the 2005 announcement, organizers were extremely tight lipped until today’s news conference at a Surrey school. They apparently didn’t do any development on the characters on internet-enabled computers, to ensure the images or information wouldn’t slip out.

The characters were designed by the Vancouver and Los Angeles-based Meomi Design. Their characters have been used as part of iGoogle, a customizable homepage option from Google, as well as Electronic Arts, Girls Inc., Time Out Magazine, Cyworld, Nick Jr., Bang-on Clothing, and CBC4Kids.

The Vancouver organizers have a CDN$46-million merchandising program; previous Olympics have made as much as $100 million from mascot-related products.

René Fasel, Chairman of the International Olympic Committee’s (IOC) Coordination Commission commented that “The IOC welcomes these imaginative new additions to the Olympic Family as they take their place on the world stage today – a symbol of the Games and of Canada. We know that when Olympians, Paralympians and visitors from around the globe arrive in British Columbia at Games time, they will fall under the spell of these captivating characters.”

The characters first appearance will be at a Bay store in the Lower Mainland; HBC is a major sponsor of the Games. They will then make their way to schools, take a break through the Christmas season, and fly to Ottawa for the Winterlude festival.

Twenty-four thousand delegates from over 132 countries are expected to attend the 16th International AIDS Conference in Toronto this week

Delegates include scientists, politicians, health care workers, government and non-governmental officials, people with AIDS and celebrities. In attendance will be Bill and Melinda Gates, Bill Clinton, Richard Gere, Olympia Dukakis and Sandra Oh.

The theme of the conference is “Time to Deliver” and is meant to focus attention on the need to meet past promises to increase funding for treatment, care and prevention. The conference began on August 13th and is scheduled to end on August 18th.

There is growing frustration with the failure of developed countries to provide drugs to combat the AIDS crisis in the developing world, particularly Africa.

“What the Western world has to do is deliver on its promises, which it never does. It always betrays the people of Africa,” Stephen Lewis, the UN secretary general’s special envoy for HIV-AIDS in Africa, told CBC News.

In the week leading up to the conference, Microsoft founder and philanthropist Bill Gates announced a donation of US$500 million spread over five years to the Global Fund to Fight AIDS, Tuberculosis and Malaria. Gates and former US President Bill Clinton will be sharing the podium during this week’s conference.

International AIDS conferences have usually been attended by world leaders, particularly the leader of the host country. Canadian Prime Minister Stephen Harper has been criticized for snubbing the conference by sending his health minister, Tony Clement, to attend in his place. The prime minister, who is touring Canada’s far north this week, officially declined his invitation to attend three weeks ago.

“It’s a dreadful mistake in political judgment, and it’s not excusable,” said Lewis, who was Canada’s Ambassador to the United Nations in the 1980s. “It’s a lost opportunity to tell the world how Canada feels about this pandemic.

“The Arctic sovereignty issue will still be there on August 18 (when the AIDS conference ends),” said Lewis. “Forty million people worldwide carry this virus, and most will die preventable deaths. What greater scourge is there than that?”

This is the second major international event Canada has hosted which Harper has snubbed. Last month, he did not appear in Montreal for the 2006 World Outgames, a celebration of elite gay, lesbian, and transgendered athletes.

The AIDS conference is expected to be the largest in history and will be ten times the size of the first which was held in Atlanta in 1985. It has become a biennial event and is convened by the International AIDS Society (IAS), an independent association of HIV professionals, with more than 7,000 members from 153 countries.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.
