Short-Radius Centrifuge at NASA
Filed under: Space Medicine
NASA has a new tool to study the physiologic effects of microgravity:
For the first time, researchers will systematically study how artificial gravity may serve as a countermeasure to prolonged simulated weightlessness."The Vision for Space Exploration includes destinations beyond the moon," said Dr. Jeffrey Davis, director of JSC's Space Life Sciences Directorate. "This artificial gravity research is an important step in determining if spacecraft design options should include artificial gravity. The collaboration between NASA, the National Institutes of Health (NIH), UTMB and Wyle Laboratories demonstrates the synergy of government, academic and industry partnerships," he added.
For the initial study this summer, 32 test subjects will be placed in a six-degree, head-down, bed-rest position for 21 days to simulate the effects of microgravity on the body. Half that group will spin once a day on the centrifuge to determine how much protection it provides from the bed-rest deconditioning. The "treatment" subjects will be positioned supine in the centrifuge and spun up to a force equal to 2.5 times Earth's gravity at their feet for an hour and then go back to bed.
"The studies may help us to develop appropriate prescriptions for using a centrifuge to protect crews and to understand the side effects of artificial gravity on people," said Dr. Bill Paloski, NASA principal scientist in JSC's Human Adaptation and Countermeasures Office and principal investigator for the project. "In the past, we have only been able to examine bits and pieces. We've looked at how artificial gravity might be used as a countermeasure for, say, cardiovascular changes or balance disorders. This will allow us to look at the effect of artificial gravity as a countermeasure for the entire body," he added.
The research will take place in UTMB's NIH-sponsored General Clinical Research Center. The study supports NASA's Artificial Gravity Biomedical Research Project.
"Physicians and scientists from all over the world will travel to UTMB to study the stresses that spaceflight imposes on cardiovascular function, bone density, neurological activity and other physiological systems," said Dr. Adrian Perachio, executive director of strategic research collaborations at UTMB. "This is an excellent example of collaboration among the academic, federal and private sectors in research that will benefit the health of both astronauts and those of us on Earth," he added.
The centrifuge was built to NASA specifications by Wyle Laboratories in El Segundo, Calif. It was delivered to UTMB in August 2004 and will complete design verification testing, validation of operational procedures and verification of science data this spring. The centrifuge has two arms with a radius of 10 feet (3 meters) each. The centrifuge can accommodate one subject on each arm.

Surgisis AFP Fistula Plug
Filed under: Surgery
Cook Inc. has received FDA clearance for its fistula plug. From the press release:
The U.S. Food and Drug Administration has cleared the Surgisis(R) AFP(TM) Fistula Plug as the first and only surgical device for repair of fistulas, Cook Biotech Incorporated announced today.A fistula is an abnormal channel that develops between body organs. The most common fistulas occur from the intestine to an opening in the skin. The presence of a fistula can be painful and seriously impact a patient's quality of life. Unfortunately, current treatments involving either an extensive surgical procedure or use of fibrin glue do not always yield satisfactory results, leaving the patient with a chronic, debilitating problem. More than 125,000 surgeries to repair fistulas are performed each year in the United States.
Surgisis AFP, sold by Cook Incorporated's Surgical Division, is a cone-shaped medical device that has been specifically designed to allow a surgeon to easily place it into a fistula channel. Once in place, Surgisis AFP serves as a bio-scaffold to facilitate well-organized tissue regeneration to close the fistula.
At the annual meeting of the American Society of Colorectal Surgeons in Philadelphia next month, Eric Johnson, M.D., Janette Gaw, M.D., and David Armstrong M.D., will present data from a clinical study that evaluated the efficacy of the Surgisis AFP device versus fibrin glue in closing fistulas. The study found an 87 percent fistula closure rate in the patient group treated with Surgisis AFP, while patients receiving fibrin glue had only a 40 percent fistula closure rate at three months.
"Surgisis AFP is easily placed, is tolerated well by patients and is showing significant improvement over conventional therapies," explained Dr. David Armstrong, Program Director of the Georgia Colon and Rectal Surgical Clinic in Atlanta, Georgia.

Autopsy: Its History and Future
Filed under: the good old days...
The New York Times Magazine looks at the history of autopsy, and the social and fiscal constraints that prevent our society from fully using this important medical tool. Some history, taken from the article:
The autopsy's intellectual founder was Giovanni Morgagni, a physician and professor at the University of Padua who wrote one of the most gruesome, humane and riveting early texts of modern medicine, ''The Seats and Causes of Disease Investigated by Anatomy.'' Published in 1761, when Morgagni was 79, the book describes nearly 700 autopsies he performed. His lucid, compassionate accounts demonstrated irrefutably that illness works in traceable, physical ways; medicine, therefore, should be an empirical endeavor aimed at particular physical processes rather than ''humors,'' spirits or other intangibles.Morgagni's perspective was carried into the present era by William Osler, a Canadian who practiced and taught medicine in the United States in the late 1800's. Osler exerted more influence on 20th-century medicine than any other doctor, primarily by creating at Johns Hopkins Medical School the model for medical education still used today, with students seeing patients beginning their third year and training in internships and residencies after graduating. Osler placed the autopsy at the center of this education, performing more than a thousand post-mortems himself and insisting that staff members and students do them regularly. Tracking the necrotic footprints of their own missteps, he believed, would teach them lessons far more memorable than any text could.
Osler's argument was strengthened in the early 1910's by the work of Richard Clarke Cabot, who reviewed the records and autopsies of thousands of patients at Massachusetts General Hospital and found that the autopsies showed clinical diagnoses to be wrong about 40 percent of the time -- the finding replicated many times since. His reports helped solidify the autopsy's central role in medical education and practice. Autopsy rates began to rise. By World War II, they were nearing 50 percent, and autopsies had become standard in medical schools and many hospitals, where weekly mortality and morbidity conferences often focused on what autopsies had revealed about the diagnosis and treatment of patients' illnesses.
That midcentury peak helped drive remarkable medical progress. In 1945, for instance, the chance of survival for a patient with an aortic aneurysm was little better than it was a century earlier. But in the 50's and 60's, surgeons like Michael DeBakey, a pioneering cardiovascular surgeon, learned through trial and error -- the errors offering their lessons only through autopsy -- how to repair and replace first lower sections of the aorta in the abdomen and then, working up toward the heart, the biggest, most pressurized and most vital sections. By 1960, aortic repairs were routine. By 1970, the lessons learned helped make open-heart surgery common as well.
Read the whole article.
If you would like to learn more about the (forensic) autopsy process step by step, you can participate in Dr. Baden's HBO interactive feature.
On this positive vibe we would like to thank you for stopping by. "The good old days" feature means that the working week is over, and a great spring weekend is ahead. Have a nice one!

Adaptive Prosthetics
Filed under: Neurological Surgery
, Orthopedic Surgery
Another promising medgadget spotlighted in MIT's Technology Review is a new generation of prosthetics with sensors. One of the scientists involved is MIT's Hugh Herr:
Some of the latest prosthetic knees on the market already have microprocessors built into them that can be programmed to help the limbs move more naturally. But Herr has taken this idea one step further. He has developed a knee with built-in sensors that can measure how far the knee is bent, as well as the amount of force the user applies to it while walking. This artificial knee--recently commercialized by the Icelandic company Ossur--also contains a computer chip that analyzes the sensor data to create a model of the user's gait, and adapt the movement and resistance of the knee accordingly......Now Herr is working to distribute those sensors beyond the knee joint, using them to detect not just the mechanical forces of the body but also neural signals from the muscles near the joint. This work is part of an emerging discipline called biomechatronics, in which researchers are building robotic prostheses that can communicate with users' nervous systems. In five to seven years, predicts Herr, spinal-cord injury patients will move their limbs again by controlling robotic exoskeletons strapped onto them (or at least they will in research settings).
We've blogged before about the high expectations on these new prostheses. But Herr has a personal stake in making it happen: he's a double-amputee, and looks forward to being among the first test subjects for his prosthetic device.

Public Access to Public-Funded Research
Filed under: Society
Well, it's about time! From the editorial at the New England Journal of Medicine:
A new era for online public access to the biomedical literature is about to begin. As of May 2, the National Institutes of Health (NIH) has asked the investigators it funds to submit voluntarily to PubMed Central (www.pubmedcentral.nih.gov) an electronic copy of any scientific report, on acceptance for publication, and to specify when the article should become public. According to the NIH, "Posting for public accessibility through [PubMed Central] is requested and strongly encouraged as soon as possible (and within twelve months of the publisher's official date of final publication)."Currently, about a third of the reports of recent NIH-funded research are publicly available in electronic form after a 12-month delay -- but from a variety of repositories and in various formats, according to Dr. David Lipman, the director of the National Center for Biotechnology Information at the National Library of Medicine, where PubMed Central was developed and is operated. Thus, the centralized archive may become a leading electronic database of biomedical literature. Articles are available without charge to the user, and registration is not required. The NIH funds 212,000 researchers worldwide, and 5000 scientists are direct employees of the institutes. Each year, these researchers publish 60,000 to 65,000 articles, accounting for about 10 percent of the articles in the nearly 5000 journals indexed by PubMed. According to the NIH, "As the electronic article increasingly becomes the authoritative and most useful document for researchers, and as scientists are actually computing on the contents of these documents -- the text itself as well as the associated data -- the impermanence of the publishers' Web sites presents a substantial risk. Creating such an archive is a historical and necessary NIH responsibility."
The NIH was spurred to develop its public-access policy by congressional pressure mounted as part of the budget process and by groups, such as the Public Library of Science, advocating "open access" to the biomedical literature. According to Dr. Elias Zerhouni, director of the NIH, the goal is to make "a change in the landscape of how scientific information is made available to the public while preserving the viability of the peer-review process."
The NIH's initial proposal would have required that scientific reports supported by the institutes be made available at PubMed Central no later than six months after they appeared in a journal. Subsequently, the agency reviewed more than 6000 comments and revised the policy "to provide flexibility to ensure maximum participation," Zerhouni said in February. The NIH, which has an annual budget of about $28 billion, estimates that the annual incremental costs of the public-access policy will be $2 million to $4 million. In addition to improving public access and creating a stable electronic archive of publications from NIH-funded research, the NIH plans to use the database to improve the management of its research investment, to monitor scientific productivity, and to help set research priorities.
As we have said earlier, this is good news for the public and for science. Scientific research is meant to be analyzed and discussed before its worth is determined. Unobstructed free access to research studies will improve the scientific review process, and indeed will improve science itself. Viva free science!

Low Cost AIDS Monitoring
Filed under: Diagnostics
Guava Technologies is partnering with several charitable organizations to bring low-cost HIV diagnostics and monitoring to 'resource-limited nations':
"Until now, the cost of commercially available CD4 diagnostic testing for patient monitoring has remained very high, and access to affordable, accurate testing methods - especially in areas outside of major urban centers - very low," said Jeff Harvey, vice president of customer solutions at Guava Technologies. "Multi-site clinical studies suggest that CD4 T cell enumeration conducted on the Guava EasyCD4TM represents a good, significantly lower cost alternative to approved "gold-standard" flow cytometry methods. The Guava assays offer comparable accuracy and reproducibility to flow cytometry-based tests, but are much simpler and up to 20 times more affordable to use. Moreover, the Guava EasyCD4TM system offers the ability to provide a more comprehensive testing system, capable of running additional assays on its easy-to-use, benchtop instrument."...Testing requires only 10 microliters of whole blood per patient, making the method suitable for use in pediatric as well as adult patients. The Guava EasyCD4 assay also requires far less reagent per sample than other testing methods, dramatically lowering the overall costs of performing the assay. Moreover, the Guava EasyCD4 assay does not require nearly the amount of dedicated laboratory infrastructure. The system also does not require large amounts of buffered water as sheath fluid that are required by conventional flow cytometers. The elimination of the use of sheath fluid also results in less bio-hazardous waste and significantly further reduces the running costs of using the system. Daily maintenance is minimal - just a fast and easy 5 minute clean and shutdown procedure performed at the end of each day.
Their system of microcapillary cytometry sounds a lot cheaper and simpler than good old flow cytometry. And I suppose the clinical questions this device will answer -- are CD4 counts below 200? responding to therapy? -- don't need quite the accuracy that flow cytometry provides.

MedGem® Metabolism Measurer
Filed under: Medicine
The Daily Mail reports that "a breath test that works out exactly how many calories you should eat has been launched in the UK."
The technology, developed by HealtheTech, works by measuring the Resting Metabolic Rate or RMR, which is the number of calories the body burns to maintain essential functions such as heart rate, brain activity and breathing.RMR can represent up to 75 per cent of the total metabolism in someone who leads a sedentary lifestyle, and is therefore an important factor in how efficiently calories will be burned off.
The machine, which has four sensors, works by measuring the difference between the amount of oxygen inhaled and exhaled.
The sensors take into account surrounding air conditions--the pressure, humidity, temperature and oxygen levels--and from that it calculates how much oxygen is used with each breath.
According to the manufacturer the device has the following features:
The MedGem measurement is easy to administer and provides accurate results in 10 minutes or less. MedGem is important for monitoring your patient's condition and resulting changes in VO2 and resting metabolic rate. Accurate VO2 and RMR is critical to nutrition assessment for successful weight management, improved medical outcomes, improved diabetic control, and overall health and wellness.Accuracy: MedGem has been clinically validated against the "gold standard" Douglas Bag technique to demonstrate accurate measurement of VO2 and determination of RMR.
Portability: Weighing less than 5 ounces, MedGem can go with you wherever you go.
Affordability: With bundled purchase options available, you can choose the right per measurement cost for your facility.
Simplicity: Plug it in, begin self calibration (30 seconds or less), and the MedGem is ready to complete a measurement in 10 minutes or less.
Sterility: No complex cleaning or sterilization procedures required, MedGem comes with single-use breathing attachments for easy preparation and clean-up.
MedGem® is an FDA-approved device.

Magnetic-Resonance Force Microscopy
Filed under: Nanomedicine
In MIT's Technology Review report about ten emerging technologies to watch for, we read about magnetic-resonance force microscopy:
In nanotechnology and molecular biology, researchers are often severely limited by the inability to observe atoms and molecules in three dimensions. Proteins, for instance, fold into complex patterns that are largely invisible to the biologists trying to work out their functions of the biomolecules.So researchers are working to develop a tool that could provide a 3-D view of the nanoworld. The technology--called magnetic-resonance force microscopy (MRFM)--is a hybrid of magnetic-resonance imaging (MRI) and atomic force microscopy (AFM), which is widely used in nanotech. Physicists at the IBM Almaden Research Center in San Jose, CA, led by Daniel Rugar, recently used MRFM to detect the faint magnetic signal--the "spin"--of a single electron. While that accomplishment is still far from the goal of a 3-D snapshot of an atom or molecule, it is a critical step in proving that MRFM could perform atomic-scale imaging.
IBM Almaden Research Center describes how MRFM works:
The magnetic resonance force microscope (MRFM) uses an ultrathin silicon cantilever (yellow) with a nanometer size magnetic tip (blue) to detect the magnetic signal from an individual electron buried below the surface of the sample. Because the electron has a quantum mechanical property called "spin," it acts like a tiny bar magnet and can either attract or repel the magnetic tip. The interaction between the spin and the tip is localized to the bowl-shaped region in the sample called the "resonant slice," which moves as the cantilever vibrates. With the aid of a high-frequency magnetic field generated by a coil (right, background), the orientation of the electron (green arrow) flips as the resonant slice passes through. The magnetic force between the electron and magnetic tip alternates between attraction and repulsion every time the electron flips its orientation, causing the cantilever frequency to change slightly. A laser beam (left) is used to measure precisely the variations in cantilever vibration frequency.

Cool Heads Needed
Filed under: Neurology
Australia's ABC reports about a new neurophysiology research tool:
The temperature of your inner ear provides a new way of understanding whether you're using your left or right brain, says an Australian researcher.Nicolas Cherbuin, a PhD student from the Australian National University in Canberra, used sensitive infrared probes to measure minute fluctuations in the temperature of inner ear membranes.
He says the temperature inside the left ear goes down when the left side of the brain is activated and the temperature of the right ear goes down when the right side of the brain is activated.
If one side is activated more than the other, the blood flow on that side is greater.
But because blood flowing to the brain is cooler than blood already in the brain, and because blood to the brain is shared by the ear, ear temperature drops, Cherbuin says.
"Because the blood in the carotid is actually cooler than in the brain, which is encased ... the blood flow from the carotid cools the brain but also the ear membrane," he says.
"Therefore what we find is that as activity in the brain increases the temperature in the ear decreases."

BROOM: A Contamination Area Management System
Filed under: Public Health
A new system from Sandia National Lab is designed to save lives following a bioterror attack:
Sandia National Laboratories researchers have developed a software-based tool called BROOM - short for Building Restoration Operations Optimization Model - to assist in the gathering of samples following a release of biological warfare agents in a public facility.BROOM is intended to help officials of airports, transportation centers, and high-traffic public buildings during planning for a possible reoccupation and return to service and assist cleanup personnel in restoration operations.
A major piece of the BROOM tool is a hand-held electronic device that assists HazMat crews in collecting and managing the many thousands of samples that are collected to characterize contamination in a facility and to verify that the facility is clean following decontamination.
Sandia researcher Mark Tucker says the main objective of the BROOM project is to develop methods to minimize the economic impact of a release of biological agent by conducting restoration operations more rapidly than can be done now.
"The current process in collecting samples is very cumbersome," says Tucker. "BROOM helps streamline the process." HazMat responders can gather samples only during short periods of time due to the heavy gear they must wear, and for safety reasons. To make it easy for the responders to carry the software tool, the researchers assembled a handheld device that incorporates the BROOM software, a barcode scanner, and a wireless laser range finder to accurately identify where the sample was taken.
The device's scanner reads barcodes placed on vials where the samples are stored. Sample barcodes provide a way to monitor the transfer of samples from the field to the lab. They also help automate the process of merging field data with laboratory results. In addition to barcodes, data specific to each sample are recorded in the handheld device.
Information such as the sample type, surface type, surface orientation, surface area, and surface texture are recorded for each sample. The sample collector records himself as the person who acquired the data and may also write additional information about the sample in a notes field.

The Jennifer Convertibles of Waiting Rooms
Filed under: etc.
We've never sat in a chair at a hospital that would ever be considered comfortable, but David Ferrarotto just won the 2005 Australian Design Award-Dyson Student Award's Silver for his concept design of the Gabrielle – Emergency Hospital Bed. It is a chair that turns into a hospital bed.
From Gizmag:
'Gabrielle - Emergency Hospital Bed' is a seat for hospital waiting rooms that folds down into a fully functional hospital bed during emergencies and disasters, when wards are full."Basically, the concept developed from a situation that arose when my grandfather was in hospital and my mum went in to stay the night with him but had to sit up in a visitors chair because of a shortage of beds. I thought, that if they had chairs, they should be able to convert them into beds and it went from there", David told Gizmag.
While the concept isn't all that new (OB delivery rooms have had "convertible chairs" for a long time), this is the first one that is designed for waiting rooms, emergency situations, comfort (go memory foam!!) and easy repair.
