2012 science clinical trials fda medicine hypothermia suspended animation tauma surgery cooling

  • The Food and Drug Administration has already approved his technique for human trials, and he has secured funding from the Army to conduct the feasibility phase. Dr. Rhee is currently lobbying for funds to conduct a full trial. If he’s successful human trials could begin as early as next year.
  • What Dr. Rhee hopes to test on humans is a method he worked out for the past couple decades on pigs. Patients would be injected with a cold fluid to induce severe hypothermia. Clinically hypothermia is characterized by the drop of a person’s body temperature from its normal 98.6 degrees Fahrenheit (37 degrees Celcius) to lower than 95 degrees (35 C). Below 95, the heart, nervous system and other organs begin to fail. The strict range is indicative of a metabolic system with strict temperature requirements for proper function (death waits only a few degrees the other way as well). Dr. Rhee’s method involves injecting patients with a cold fluid that would bring the body’s temperature down to 50 degrees Fahrenheit (10 C). Sounds chilling, but when he induced the extreme hypothermia in pigs they came out just fine. Heart function, breathing, and brain function was completely normal.
  • Dr. Rhee is no stranger to high-stakes medicine. The native South Korean was trained at the Uniformed Services University Medical School in Bethesda, Maryland. Following a fellowship in trauma and critical care at the University of Washington’s Harborview Medical Center he served in the US Navy as director of the University of South California’s Navy Trauma Training Center at Los Angeles County. He was then sent to Afghanistan where he was one of the first surgeons at Camp Rhino. Later he started the first surgical unit at Ramadi, Iraq. His cool under fire was on display nationally as he performed surgery on US Representative Gabrielle Giffords after she was shot through the skull in the Tucson shootings this past January. His experience with induced hypothermia came into play the night of the shootings when Dr. Rhee removed part of the congresswoman’s skull. The wound had raised her body temperature and began “cooking the brain.” He used a device to cool Rep. Giffords’ skin.

  • They are currently working on 'smartware', fabrics that treat chronic wounds that result from diabetes and leg ulcers. Their 'senseware' technology, which is motion sensors found inside textiles, can give medical professionals the tools they need to detect the onset of epileptic seizures. The centre's 'bioware' technology is embedded materials and surfaces found in the home and on the body.

Artificial spleen cleans up blood : Nature News & Comment - 0 views

  • A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on 14 September in Nature Medicine1.
  • Blood infections can be very difficult to treat, and can lead to sepsis, an often-fatal immune response. More than 50% of the time, physicians cannot diagnose the cause of an infection that has prompted sepsis, and so they resort to antibiotics that attack a broad range of bacteria2. This approach is not always effective, and can lead to antibiotic resistance in bacteria.
  • To test the device, Ingber and his team infected rats with either E. coli or Staphylococcus aureus and filtered blood from some of the animals through the biospleen. Five hours after infection, 89% of the rats whose blood had been filtered were still alive, compared with only 14% of those that were infected but not treated.

  • the device had removed more than 90% of the bacteria from the rats' blood.
  • The researchers then tested whether the biospleen could handle the volume of blood in an average adult human — about 5 litres. They ran human blood containing a mixture of bacteria and fungi through the biospleen at a rate of 1 litre per hour, and found that the device removed most of the pathogens within five hours.
  • That degree of efficacy is probably enough to control an infection, Ingber says. Once the biospleen has removed most pathogens from the blood, antibiotics and the immune system can fight off remaining traces of infection — such as pathogens lodged in the organs, he says.

      In short, it remove enough pathogens to be an effective human treatment.

    The new EPI Life mobile phone comes complete with mini electrocardiogram. "We think it's a revolution. It has clinical significance," EPI medical chief Dr. Chow U-Jin said at the mobile industry's annual conference in Barcelona. "Anywhere in the world you can use it as a phone but you are also able to transfer an ECG and get a reply," Chow said. "If you get a normal reply it will just be an SMS," he added. "If it's severe, you get a call: 'Sir, an ambulance is on the way'." EPI Life has three hospitals in Singapore, all of which carry the phone users' history. EPI Life costs $700 (516 euros), the price of a top range smartphone, and 2,000 of them have been on the market since 2010.

    BGU software engineering students have developed innovative technology that could enable people to operate a computer without using a keyboard or mouse - only their brainwaves. While there have been previous attempts to develop devices to read brainwaves and operate specific programs, they were cumbersome and not feasible outside of a laboratory setting. The BGU technology features a helmet equipped with 14 EEG connect points that sense brain activity. According to Dr. Rami Puzis, "The technology is designed to assist those who are physically disabled who might otherwise be unable to manipulate a computer mouse or keyboard." The student team, Ori Ossmy, Ofir Tam and Ariel Rozen, developed the prototype application for their bachelor's degree project under supervision at BGU by Prof. Mark Last, Dr. Rami Puzis, Prof. Yuval Elovich and Dr. Lior Rokah. As part of a recent demonstration, a student composed and sent a hands-free e-mail using only thought combined with the adaptive hardware.
