With a new probe, smart phones can be used to capture and send ultrasound images.
By Lauren Gravitz
Physicians rely on ultrasound imaging for everything from monitoring fetal and cardiac health to providing guidance when placing catheters and central lines. Most of the time, however, the systems are large and cumbersome--handheld probes attached to wheeled computers the size of filing cabinets. They're also quite pricey: the larger, more versatile systems can cost $25,000 or more. Self-contained pocket-sized systems do exist but cost about $10,000. Nothing available today provides a low-cost, mobile solution that can be used remotely to both gather and transmit images.
The compact ultrasound probe, developed by computer engineers at Washington University, in St. Louis, has the potential to do all of that and more. Prompted by a grant program at Microsoft that called for the design of smart-phone-enabled medical devices, William Richard and David Zar started with an instrument that they developed five years ago: a $2,000 ultrasound probe that can plug into a laptop's USB port. Richard transferred all of the computing power into the probe itself and decreased its power draw to just half a watt; Zar created the necessary software and drivers.
To squeeze such capabilities into the probe, Richard and Zar had to make some concessions. In order to decrease its power requirements, Richard had to also decrease the amount of data that the instrument transmitted. The images themselves are smaller and less detailed than those from a full-size ultrasound. But while it has yet to undergo rigorous testing and comparisons, the researchers believe that its capabilities should be more than sufficient for many medical applications. They point to a number of potential uses: remote medicine for rural communities and developing nations, emergency imaging of patients en route to the hospital, battlefield medicine, and even home use in patients with chronic diseases. "Looking back on this 10 years from now," Richard says, "these are going to be used in places we never would have imagined."
The most obvious and immediate use is providing care for people in underserved communities, both in the United States and abroad. Even in some of the poorest nations, cell-phone networks are fairly ubiquitous and could be used to immediately send images taken by the probe to a trained medic for interpretation.
Gari Clifford, a computational physiologist at the Harvard-MIT Division of Health Sciences and Technology, is interested in incorporating the new ultrasound probe into a remote medicine system that he's developing. By prescreening pregnant women in remote areas for dangerous complications, "we can advise them to go into a more urban and centralized clinic to give birth," he says. "Many rural clinics in developing countries really don't have the expertise or technology to do this kind of screening."
Shadab Mahmud, a program manager at Grameen Healthcare, offers a similar vision. The nonprofit, which is part of the same group of enterprises as the Nobel-winning Grameen Bank, was recently launched to provide sustainable health care in Bangladesh. "In developing countries, about 95 percent of the births occur at home, and that's where most of the deaths occur as well," Mahmud says. "The ultrasound probe is an integral part of a kit that each and every community health worker would have."
A number of groups have already expressed interest in the device. According to Zar, for the same $2,000 that buys the laptop-based probe he helped develop, the manufacturer can build the smart-phone version, and he aims to have open-source software available this summer. (The user must also have a compatible phone; currently, only a few have the necessary capabilities, such as a USB port that can read input and provide power.) Richard is already looking further ahead: his goal now is to create a $199 version that could one day be sold in drugstores for home use.

If you want to lose weight, move closer to your food:
But the study's author, the esteemed Larry Frank, notes that grocery stores are only part of the story.
Frank's research has consistently shown that people who live close to a mix of stores and services tend to walk more. So the lesson here isn't to move closer to a grocery store. Instead, we should be looking to foster mixed-use neighborhoods, where more and more people can do some of their errands on foot, rather than being forced to drive for every trip.

Un post un peu "gag", mais cqfd une fois de plus qu'il est positif à maints points de vue d'habiter un quartier, un morceau de ville où l'on peut se déplacer à pied pour réaliser la polupart de ses achats et/ou partie de ses occupations sociales.

We continue to learn a tremendous amount since launching Google Health in the spring of 2008. We're listening to feedback from users every day about their needs, and one issue we hear regularly is that people want help coordinating their care and the care of loved ones. They want the ability to share their medical records and personal health information with trusted family members, friends, and doctors in their care network. I can relate to this.
For doctors and family members who are not yet online, we've also made it easier to share a hard copy of your information via our new printing feature. The wallet format prints a wallet-sized card that includes a user's medications, and allergies; the PDF format prints a letter-sized copy of a user's profile, including medications, allergies, conditions, and treatments.
Finally, we've launched a new graphing feature that helps patients visualize their medical test information. This is great for, say, someone who has high cholesterol. They can use Google Health to enter their lab results on a monthly basis and see the trend over time.
There is still a lot more work to do on Google Health, and we're excited to keep hearing from you so we can continue to make improvements. For now, we hope this new sharing feature makes coordinating your care, or the care of loved ones, a little easier.
Si ça va pas être amical ça!? Le réseau social médical où l'on pourra se partager nos petits bobos ("moi j'ai une entorse à la cheville et toi aussi, devenons friends!"! Franchement ...

[Image: From "Change of Heart: Rethinking the Prescriptive Medical Environment" by Marina Nicollier].
To perform a test-run for these propositions, Nicollier has designed a "cardiology research facility adjacent to two major medical institutions in Mexico City."
Then, however, in the 1950s it was discovered that tuberculosis was only treatable through the use of antibiotics, and so architectural modernism – with its wide verandahs and flat roofs – lost its medical justification, so to speak. It became just another style to be mined for a new pastiche of superficial quirks and regional variations.
To wit, Thomas Mann's Magic Mountain.
Je ne serais pas étonné d'apprendre que Marina Nicollier soit passée par un atelier de Philippe Rahm à l'EPFL, à Mendrisio ou à la AA, car le projet ressemble beaucoup à ce que j'ai pu voir en critique dans son atelier. Reste que le projet est intéressant et renvoie dans le fond à des architectures de type sanatorium!

The first health-promoting mobile phone technology in the world
Sleep disorders are very common in modern society. Mild forms are familiar to everyone and up to 10 – 20 per cent of adults suffer from related diseases (organic sleep disorders). Diagnosing sleep disorders often requires extensive and expensive sleep recording at a sleep laboratory. At the moment, there are hardly any good screening methods for detecting sleep disorders.
Research conducted in two Finnish universities, Tampere University of Technology and the University of Helsinki, resulted in the development of a brand-new technology for screening and even diagnosing sleep disorders. The first application of the new technology, a smart alarm clock for mobile phones, HappyWakeUp®, is now available. It is the first health-promoting mobile phone application in the world.
In Tampere University of Technology MSc Väinö Virtanen started to record and analyse snoring two years ago to develop a simple screening method. "Very soon we noticed that a common microphone is very sensitive to any sounds and voices produced by movements in the bed during night-time. Everyone has heard the typical voices, when a mobile phone has accidentally called you from someone's pocket", says sleep specialist Tapani Salmi, MD, PhD.
Based on the new technology, the sleep research group developed the smart alarm clock for mobile phones called HappyWakeUp. The smart alarm clock gives an alarm signal in the morning just before the ultimate alarm time, if the sleeping subject is awake or "almost awake" due to the natural sleep rhythms. During these moments, the body and brain are already awake and waking up is natural and easy "It is rather an arousal clock than an alarm clock", says Salmi.
The alarm time is set normally with the mobile phone. The mobile phone is located beneath the pillow or the bed linen or near the sleeping subject. The appropriate almost-awake moments are detected by using a microphone and statistical analysis of voices. During the last 20 minutes before the ultimate alarm time, the analysis is activated to give a soft alarm signal, if there are movements indicating that the sleeping subject is awake or "almost awake". If the subject is sleeping calmly, no alarm signal is given before the ultimate alarm time.
"The alarm signal during deep sleep is stressful and familiar to everyone, but with the smart alarm clock this is avoided. After a trial period of some days or a week, you start to notice the benefits", promises Salmi. The continuous use of the clock helps the internal clock in your brain learn the proper sleep rhythms. "Pleasant mornings help avoid stress in your body and brain. Elevated stress-levels are associated with several risk factors and even diseases, such as hypertension and problems with the heart and brain. HappyWakeUp is not a medical product or treatment to any disease. "In case of sleep-associated diseases and symptoms you should contact your doctor", says Salmi.
HappyWakeUp® is available for Nokia smart phones based on S60 3rd ed FP1 platform at www.happywakeup.com. A one-week trial period costs €2. A two-month trial period and a permanent license are also available.
The sensitive microphone recording could also be used in monitoring other aspects of sleep. The detection of restless sleep, leg movements associated with the restless legs syndrome and screening for snoring and sleep apnea are possible by employing the same technology. The technology makes it possible to perform several repeated all-night recordings and to diagnose sleep disorders in countries and areas with no previous sleep recording facilities. The new technology is extremely cost-efficient, compared to the use of existing special medical recording devices.
The company Smart Valley Software Ltd. is developing the technology into a commercial product, supported by the Finnish Invention Foundation and the Finnish Funding Agency for Technology and Innovation (Tekes) in patent applications.

Microphone to detect other sleep disturbances
Could every morning be equally pleasant?
Santé, wellness &/or wellbeing & smart phone: une nouvelle "niche business". Mais aussi peut-être une nouvelle manière d'organiser son temps (gestion d'agenda?), basée sur des rythmes biologiques repérables, "monitorables" par le téléphone (on pourrait penser aussi à l'accéléromètre, le gps, év. des capteurs non encore présents dans la téléphone, etc.)?
