Soldiers to Use Virtual Reality

Canadian soldiers returning from the war in Afghanistan will soon be using virtual reality to help recover from the survivable wounds of war. It should only be a matter of time before others are able to access this advanced technology too.

People learning to use an artificial limb or recovering from a stroke will be able to walk, drive or even swim through a variety of virtual environments without leaving the safety of the hospital — almost like on the holodeck of the fictional Starship Enterprise.

“With [post-traumatic stress disorder], the therapy is often on reintroduction of the scenarios that caused it in the first place,” he said.

“With this, you can virtually create the scenario that caused it in the first place — whether it’s on the battlefield, a car accident — and gently re-introduce the individual. That’s what allows a person to get back into their real life without the fear of constant flashbacks.

Maybe in the future soldiers can use virtual reality to fight their wars in.

Smoking Bans Decrease Hospitalization

Toronto phased in a ban on smoking starting in 1999 and ending in 2004 and the results are in: banning smoking was (and still is) a good thing.

“It confirms that public policy can make a difference,” said Dr. Alisa Naiman, lead author of the study published Monday in the Canadian Medical Association Journal.

The Institute for Clinical Evaluative Sciences study was the first to look at the effect of anti-smoking legislation on a wide range of smoking-related conditions. It examined three cardiovascular ailments — heart attacks, strokes and angina — and three respiratory ones — asthma, pneumonia and chronic bronchitis and emphysema. Previous studies have focused solely on heart attacks.

Naiman said researchers were surprised by the findings’ consistency — the fact that hospital visits plummeted in much the same way for both cardiovascular and respiratory conditions.

Hospitalization for cardiovascular conditions dropped 39 per cent, including a 17.4 per cent decrease in heart attacks, while hospital visits for respiratory conditions fell by 33 per cent.

Why Finnish Schools Always Finish First

Education is a very important part of any good society and a good equational system makes for a better world. In Finland, they have found a way to have a relaxing, effective, and the world’s best educational environment. The BBC has an article with some videos (which I can’t embed here) on the awesomeness of Finnish schools.

The Finnish philosophy with education is that everyone has something to contribute and those who struggle in certain subjects should not be left behind.

A tactic used in virtually every lesson is the provision of an additional teacher who helps those who struggle in a particular subject. But the pupils are all kept in the same classroom, regardless of their ability in that particular subject.

$3 Wound Healing Device Saving Lives in Haiti

A student at MIT has created a device that helps people heal after severe wounds that costs a fraction of what commercial options cost. The device is a portable version of the negative-pressure devices that accelerates wound healing and reduces the frequency that bandages need to be changed. Commercially available devices cost about $100 and require a lot more energy than the MIT designed $3 device.

Negative-pressure devices, which act like a vacuum over the bandaged wound, have become a central part of wound therapy in the United States over the last decade. They speed healing up to threefold, depending on the type of wound, and in some cases eliminate the need for plastic surgery or skin grafts. A number of commercial versions are available in the U.S. and are used to treat burns and chronic wounds such as bed sores or diabetic foot ulcers. While scientists don’t exactly know why this treatment accelerates the healing process, it likely helps by removing some of the fluid and bacteria that accumulates at the injury site and by increasing blood flow to the wound. The pressure itself may also help healing by bringing together the edges of the wound and delivering mechanical pressure, which has been shown to spur cell growth, says Dennis Orgill, a surgeon at Brigham and Women’s who was not involved in the project.

Existing devices are often heavy, about five to 10 pounds, and require an energy source to create the vacuum, making them difficult to apply in disaster settings. Texas-based KCI, the leading maker of negative-pressure machines, has a portable version that’s battery powered, but it costs approximately $100 per day to rent. A number of companies are working on even more portable versions, say Orgill.

Vancouver Safe Injection Site Survives

Vancouver’s Insite is the first safe injection site in North America. The project has been shown to reduce public drug use, needle sharing, littering, and increase addiction treatment. The Canadian government has been trying to shut it down recently, but in January, Insite won a court battle that recognized them as providing an “essential medical service.”

The B.C. Court of Appeal has dismissed a federal government appeal, which means InSite, the Vancouver supervised safe-injection site that was the first of its kind in Canada, will remain open.

The federal government is expected to appeal Friday’s split 2-1 ruling to the Supreme Court of Canada.

Vancouver Mayor Gregor Robertson reacted by saying he strongly supports the ruling and the continued operation of InSite to improve the lives of drug addicts.

“With this second consecutive decision in favour of InSite, I hope the federal government will drop its legal efforts so that we can go back to focusing on InSite for what it is — a harm reduction facility that saves lives and improves health outcomes for those living with addictions,” the mayor said in a statement.
