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.

A three-day United Nations (UN) summit, bringing together leaders from 181 countries, has wrapped up with a pledge by all attending countries to address the global food shortage crisis. Key actions cited include doubling the world’s food production by 2030, providing resources for farmers in poor countries and increasing humanitarian aid in times of crisis.

Protests and violent riots have resulted in parts of the world in recent months due to increasing unaffordability, and sometimes unavailability, of food. It is estimated that 862 million people, or just over one eighth of the world’s population, are malnourished.

According to UN Secretary General Ban Ki-moon, up to US$20 billion will be required annually to avert crises in the most hard-hit areas. The UN Food and Agriculture Organization (FAO) has put the figure closer to US$30 billion. Pledges made just at the summit amounted to more than US$5 billion, according to the UN.

Despite the largely positively-received outcome of the summit, held in Rome, Italy, there were some who felt that the proceedings could have gone better. Several non-governmental organisations (NGOs) pointed to the fact that they were not invited to partake in the discussions. Food and hunger policy adviser Magda Kropiwnicka of ActionAid commented on the strength of the final pledge: “There were no quantifiable financial commitments. Apart from the existing UN Food and Agriculture Organisation funds, no money has been given to address the key problem of boosting capacity.”

While most delegates agreed that biofuels have been one of the causes of the food crisis, no actions were agreed upon to address this hot topic. Biofuels have been increasingly in demand in recent years, meaning that many crops that would have previously been used for food are now being used as fuel.

The impact that biofuels has goes further than simply increasing the demand of food crops. As fuel prices increase, so do the costs of fertilisers, farm vehicle use and the transport of foods. All of this adds up to a large increase in the cost of food.

Some UN officials say that biofuel use has caused up to 30% of the global food price inflation of late. The United States estimates that figure to be closer to just 3%. The Globe and Mail newspaper indicates that some estimates go as high as 60%. The only consensus that could be reached on biofuels is that they provide both “challenges and opportunities”, and need to be looked into further for a conclusive analysis on their impact on food production.

Other factors increasing food prices are increased consumption of meat and dairy products in developing nations like China and India. Argentina noted that subsidies granted to farmers from the US, the European Union and other Western countries have also been a major player in the increase.

From September 3 to 8, experts gathered at the 10th International Congress on Obesity in Sydney, Australia, to discuss what they call the worldwide “obesity epidemic”. According to the World Health Organization (WHO), 1 billion people in the world today are overweight, and 300 million of those are obese. “Obesity and overweight pose a major risk for serious diet-related chronic diseases, including type 2 diabetes, cardiovascular disease, hypertension and stroke, and certain forms of cancer“, a WHO fact sheet states. According to AP, experts at the conference “have warned that obesity is a bigger threat than AIDS or bird flu, and will easily overwhelm the world’s health care systems if urgent action is not taken”.

Of particular concern is the large number of overweight children. Dr. Stephan Rossner from Sweden’s Karolinska University Hospital, a leading obesity expert who was present at the conference, has warned that as a result of the increasing number of overweight children, “we will have, within a decade or two, a number of young people who are on kidney dialysis. There will not be organs for everybody”. UK-based International Obesity Task Force has said that junk food manufacturers target children, for example, through Internet advertising, chat rooms, text messages, and “advergames” on websites. Politicians are not doing enough to address the problem of obesity, including childhood obesity, the experts said.

According to Wikipedia, examples of junk food include, but are not limited to: hamburgers, pizza, candy, soda, and salty foods like potato chips and french fries. A well-known piece of junk food is the Big Mac. The US version of just one Big Mac burger contains 48% of calories from fat, 47% US Recommended Dietary Allowance (RDA) of fat, 52% RDA of saturated fat, 26% RDA of cholesterol, 42% RDA of sodium, and little nutritional value. It also has 18% of calories from protein. According to WHO, most people need only about 5% calories from protein. Staples such as rice, corn, baked potatoes, pinto beans, as well as fruits and vegetables such as broccoli, cauliflower, zucchini, oranges, and strawberries, provide more than this required amount of protein without the unhealthy amounts of fats or sodium, without cholesterol, and with plenty of fiber, vitamins, and minerals.

Both WHO and the American Centers for Disease Control and Prevention (CDC) define overweight in adults as a Body Mass Index (BMI) of 25 or above, and obese as a BMI of 30 or above. To combat overweight and obesity, WHO recommends that, among other things, people should be taking the following steps

• eating more fruit and vegetables, as well as nuts and whole grains;
• engaging in daily moderate physical activity for at least 30 minutes;
• cutting the amount of fatty, sugary foods in the diet;
• moving from saturated animal-based fats to unsaturated vegetable-oil based fats.

Ian Narev, the CEO of the Commonwealth Bank of Australia, this morning “unreservedly” apologised to clients who lost money in a scandal involving the bank’s financial planning services arm.

Last week, a Senate enquiry found financial advisers from the Commonwealth Bank had made high-risk investments of clients’ money without the clients’ permission, resulting in hundreds of millions of dollars lost. The Senate enquiry called for a Royal Commission into the bank, and the Australian Securities and Investments Commission (ASIC).

Mr Narev stated the bank’s performance in providing financial advice was “unacceptable”, and the bank was launching a scheme to compensate clients who lost money due to the planners’ actions.

In a statement Mr Narev said, “Poor advice provided by some of our advisers between 2003 and 2012 caused financial loss and distress and I am truly sorry for that. […] There have been changes in management, structure and culture. We have also invested in new systems, implemented new processes, enhanced adviser supervision and improved training.”

An investigation by Fairfax Media instigated the Senate inquiry into the Commonwealth Bank’s financial planning division and ASIC.

Whistleblower Jeff Morris, who reported the misconduct of the bank to ASIC six years ago, said in an article for The Sydney Morning Herald that neither the bank nor ASIC should be in control of the compensation program.

Alex Tew, a student in England, has almost reached his target of one million dollars on his website: Million Dollar Homepage. He came up with the idea after jotting down ideas before he went to bed on how to become a millionaire before he went to university. Then he came up with the million-dollar idea: selling pixels at USD $1 each on a web page. Alex currently believes he can make his goal by the end of 31st December, 2005.

Advertising companies especially appreciate the website, as they wish to “make Internet history” on the Million Dollar Homepage. In fact as of writing, he has already made USD $999,000. The student says advertisers get to keep their ads for a period of five years from purchase and he says he will use the money he has made to guarantee it. Alex has said he has already got numerous job offers from companies aiming to secure his money making talent.

Tew is undergoing a business management course at Nottingham and needed GBP £7000 a year to complete his studies. He is understandably overwhelmed by the success he has achieved: “It’s just nuts. I’m in a state of disbelief. It’s like Monopoly money but then I look at my bank account and there’s a lot of cash in it.” The British National Union of Students claim that 90% of students are in debt. However, what only worries him is how he’s going to spend his money. He has already spent some of his money on a car for himself, as he thinks of what to do with his new fortune.

His website’s method is simple; his website is made up of one page divided into 10,000 boxes, each 100 pixels in size. Companies can buy one or more boxes for USD $100 each and cover it with a logo, which, when clicked on, transports web users to the customers’ own site.The figures add up with the site now carrying over 240 advertisements and has 30,000 hits a day. Even the actor Jack Black, star of “School of Rock” and “Shallow Hal“, is using the site to advertise his band Tenacious D.

An Orizont oil platform in the Persian Gulf, owned by the Grup Servicii Petroliere (GSP) of Romania, has allegedly been boarded by Iranian troops after being fired at by a helicopter. Romanian officials have not “heard anything” from the workers on the platform “since then [the attack].”, according to a company statement. The Iranian news agency IRNA claims that the personnel who boarded the platform were not “troops” but “police”.

“We were called by one of our employees at 9.15 a.m. local time (0615 GMT), who told us a military helicopter opened fire against the Orizont rig, and by 9.45 Iranian troops got on board. Since then, we haven’t heard anything from them,” said Radu Petrescu, a spokesman for Servicii Petroliere.

According to a representative of GSP, Lulu Tabanesku, “Iranian [troops] used machine guns” and Iran is “in control of the rig. We cannot contact the rig.” There were at least 26 workers on the 13,000-ton platform when it came under fire. There is no word on whether there are any casualties.

The Foreign Minister of Romania is scheduled to have a meeting to discuss the attack with Iranian officials on Wednesday, but so far Iran has yet to release an official statement regarding the attack. Romanian president Traian B?sescu was unable to reach Iran’s president Mahmoud Ahmadinejad on Tuesday, the day of the rig’s seizure. August 22 is an Iranian National holiday.

The Romanian company GSP operates the Orizant and Fortuna rigs that are both subjects of a legal dispute with the Oriental Oil Company who rents the oil rights to Petro Iran Development Company (PEDCO), a broker for the National Iranian Oil Company. According to PEDCO, an Iranian court ruling in the contract dispute between the two companies found that both rigs should remain in Iranian waters. GSP moved the Fortuna rig on August 15, claiming the contract was cancelled illegally, Iran accused the Romanians of “hijacking” the platform.
