534534635 Supervision Is Coming?Medgadget tipster Tom Brander alerts us to an article at Wired, about a company called PixelOptics of Roanoke, Virginia, that has just won a $3.5 million Pentagon grant to realize its “supervision” technology. The company is trying at first to develop its technology for electro-active spectacles that correct for presbyopia. Wired explains:

At the heart of PixelOptics’ technology are tiny, electronically-controlled pixels embedded within a traditional eyeglass lens. Technicians scan the eyeball with an aberrometer — a device that measures aberrations that can impede vision — and then the pixels are programmed to correct the irregularities.
Traditional glasses correct lower-order aberrations like nearsightedness, farsightedness and astigmatisms. PixelOptics’ lenses handle higher-order aberrations that are much more difficult to detect and correct.
Thanks to technologies created for astronomical telescopes and spy satellites, aberrometers can map a person’s eye with extreme accuracy. Lasers bounce off the back of the eyeball, and structures in the eye scatter the resulting beam of light.
Software reads the scattered beam and creates a map of the patient’s eye, including tiny abnormalities such as bumps, growths and valleys. The pixelated eyeglass lens is then tuned to refract light in a way that corrects for those high-level aberrations.

According to the company, its future lenses “… may have the ability to dynamically change to ones environment and thus can adjust for aberration changes caused by the environment or working conditions (for example lighting, altitude, convergence / divergence, tear blink). Individuals of numerous occupations, sports and hobbies can benefit from better vision.”

23232351652 Impella Recover Devices Approved in Germany for Reimbursement
Impella Recover line of cardiac support devices, manufactured by Impella CardioSystems GmbH, has received the highest approval level for reimbursement by the German governmental authority for healthcare (InEK). We have covered the technology in 2004. Since then the company has introduced a number of devices for a variety of supports: biventricular, left ventricular, right ventricular, the support via the femoral artery, the general peripheral support, and others.
This is how the system for LV support works:

The pump is inserted directly into the heart via the ascending aorta and is advanced through the aortic valve and into the left ventricle. It can remain implanted supporting the heart for up to 7 days.
Thus positioned, the pump draws blood from the left ventricle and delivers it into the ascending aorta. The pump is capable of supporting the human heart by delivering a total of up to 5 liters of blood per minute. The system is generally implanted after the thorax has already been opened for heart surgery.

The cool technology:

Development of the Recover® System was based upon Impella’s platform technology. An electric motor with a diameter of only 6.4 mm assures pump delivery rates of 5 to 6 liters per minute. Recover® is thus the world’s smallest and, above all, the only truly minimally invasive, mechanical cardiovascular support system. After all, the smaller the system to be implanted, the less invasive the surgery is for the patient. And the Impella system is so small that it can be inserted into the heart via the groin without opening the thorax and can be removed in the same way.
The micro-axial pumps keep damage to the blood to a minimum as well, the extent of which is greatly dependent upon the size of synthetic surface areas. The use of hemodilution medications can thus be significantly reduced as well (heparin). Due to the fact that a fully implantable system with micro-axial pumps is utilized (i.e. only one cable with a diameter of 3 mm (9F) exits the patient), the danger of infection is also extremely minimal. The system consists of the fully implantable Recover® LD & Recover® RD pumps, an impella®mobile console for controlling the system and the impella®purger for rinsing the pumps. The system is used all over Europe for providing temporary cardiovascular support.

Newsflash– being an obstetrician doesn’t mean living in a hosptial 24/7.. (well just not as much)
Obstetrician1 Ob/Gyn   powered by GE!
GE Healthcare announced today an exclusive agreement with MP4 Solutions (MP4) to deliver the Centricity Perinatal Solution in conjunction with AirStrip OB(R), a state-of-the-art technology that allows obstetricians to use their PDAs (personal digital assistants) or Smart Phones to remotely access fetal heart tracings, maternal contraction patterns, and other critical, virtual real-time data from labor & delivery units. This breakthrough technology will be showcased next week at the 2006 Healthcare Information and Management Systems Society (HIMSS) Annual Conference & Exhibition in San Diego.

The MobileCME on-the-go learning system is a free service that enables medical professionals to earn CME credits on their mobile device, wherever they are, whenever they have time. It takes online CME (which is now 14 percent of all CME) a step further and brings it to handheld devices. Since its introduction in early 2005, Epocrates has more than 120 courses across multiple specialties available and has issued more than 175,000 certificates for physicians through its partners. The CME content is created by providers such as Johns Hopkins University School of Medicine and University of Virginia Health System.

Each MobileCME course consists of an educational article followed by a brief five-to-ten question post-test. After successfully completing the post-test, the physician can submit the activity for CME credit from the accredited provider. When users synchronize their handheld devices to the Internet, the results of completed CME programs are sent to Epocrates. After receiving the results, an accredited CME provides e-mail certificates to the users verifying the credits earned. New CME courses are routinely added and can be easily downloaded to users mobile devices and completed at leisure. The mobile functionality of the program enables doctors to start CME courses on their own time and complete the course work at their own pace, with no need to be connected to any system. It’s a great way to keep current with new developments, as well as meet your CME responsibilities (and a way to sleep late and skip Grand Rounds.. shh…)

 Bottoms Up, Down Under
What did mom always say?

1. Always wear clean underwear
2. Take your vitamins

Now you can do both at the same time! Medgadget tipster Sherwin S. informs us about Aussie Bum Essence, the new underwear that secretes vitamins into your skin:

The company says it has created a fabric that can hold liquid vitamins, and when the body heats up, those vitamins can be absorbed by the skin. They can even withstand 15 washings.
Recchia: “These babies are comfortable. When I first put them on it was sorta like Vicks Vaporub … it was cooling and gentle.
But can your skivvies really provide you with the same benefits as eating fruits and veggies or taking supplements?
Julie Upton, Nutritionist: “It’s very funny to say you have a vitamin laced pair of underwear. Is it going to do anything? No, probably not. But it’s probably not going to hurt you either.”
Universal Gear in Chelsea still plans to sell the Aussie Bum underwear because they understand the bottom line.
“It’s not just about having clean underwear, it’s about having fun underwear,” a store clerk said.

So often the source of emissions, it’s quite a shock to view this area of the body as a source of intake and nutrition.
But before you get your panties in a bunch, a quick scan of the literature reveals that some latex-allergy sufferers also manifest skin reactions to acerola (Barbados Cherry, the additive to Aussie Bum’s new garments).
We definitely do not want to see genital anaphylaxis in the emergency department (indeed, the edict about wearing clean underwear was supposed to prevent embarassment in the event of an accident, not cause it.)

uti test New Biosensor Technology Used to Rapidly Diagnose Urinary Tract Infections
A press release from UCLA is reporting that in a partnership between the university, GenFluidics, a Monterey Park, CA based company, and the VA of the Greater Los Angeles Area, researchers used a new biosensor to correctly identify infection causing bacteria species in 98 percent of samples. A big advantage of the new method: it takes 45 minutes to get results, rather than two days.

Individual sensors on GeneFluidics’ 16-sensor chips were coated with UCLA-designed species-specific genetic probes. Clinical urine samples were directly applied to the chips and the electrochemical signal subsequently measured by GeneFluidics’ multi-channel reader instrument. The urinary tract infection pathogens were identified by examining which signals on the sensor chip were elevated. The entire experiment from sample collection to result read-out took only 45 minutes.
The potential for rapid bacterial detection was discovered in the laboratory of Dr. Edward McCabe, chair of pediatrics at the Mattel Children’s Hospital at UCLA and an adviser to GeneFluidics. McCabe’s group demonstrated that probes could bind to species-specific bacterial sequences within minutes, rather than hours. These exciting results were translated to the biosensor protocol, leading to the development of the biosensor for rapid identification of bacteria in urine from patients with urinary tract infections.
“Results were impressive for this initial 78-sample clinical study,” said Dr. Bernard Churchill, chief of pediatric urology at the Clark-Morrison Children’s Urological Center at UCLA and principal investigator. “By coupling UCLA’s robust probes with GeneFluidics’ ultra sensitive biosensor system, we were able to identify urinary tract infection pathogens in a time frame that would enable physicians to make dramatically superior clinical decisions.”
Ongoing work at UCLA and the VA Medical Center is focused on developing even better detection methods to bring the urinary tract infection biosensor chip from “bench to bedside.” At GeneFluidics, engineers are integrating the biosensors into microfluidic cartridges and building a new instrument for faster and completely automated experimentation. The team anticipates the rapid test could become available in the next two to three years.
