A heart attack patient can count on CPR and a defibrillator as tried and true methods to help save them. But a new device that looks like a sleeping bag could be the next tool to save cardiac arrest victims. The Shock Sheet, invented by an anesthetist in England, fits over the legs. A pump inflates the shock sheet, squeezing blood that's pooling in the lower extremities and force it back to the heart and brain. The device has only been tested on healthy volunteers, but has shown it can increase blood pressure when inflated.
Glass might seem an unusual source for bone repair, but it's bearing its weight in research. Engineers at the University of Missouri-Rolla are working with biodegradable glass, both crushed and in spherical form. Broken or diseased bones may one day be filled with a caulk-like substance made from crushed glass and a polymer. Other research is focusing on glass spheres filled with radiation that will treat arthritic joints. Researchers say the glass is treated like a natural product in the body, and forms a chemical bond to the bone.
Flumist, the newest kid on the flu vaccine block, is raising red flags for people with primary immune deficiency diseases. The Flumist vaccine contains live virus particles. So, simply sneezing or coughing can transmit the virus and result in serious illness for people with inherited immunity disorders. The Immune Deficiency Foundation urges PI patients and their families not to get any vaccine made with a live virus. Doctors should also be consulted to see if preventive medicine should be taken to avoid infection.
The Lubbock Health Department offers the flu shot for just $5 dollars for kids or $10 for adults, but Flumist is quite a bit more. Reportedly, private clinics charge around $80 for the nasal spray and even at the health department, Flumist will cost you $50.
