Countdown to Medicine X: 3D printing takes shape

Countdown to Medicine X: 3D printing takes shape

3D printed handFrom customizing lab equipment to assisting in surgical planning to developing models of proteins and pathogens, 3D printing is helping to reshape biomedical research and health care. This year, Medicine X (which kicks off one week from today) will explore the transformative force of the technology during a range of panels and demonstrations in the “3D Printing and the Future of Medicine” session.

During the session, attendees will have the opportunity to learn more about health-care related 3-D printing applications at the “3-D Experience Zone,” which will showcase technologies from leading manufacturers. Attendees can learn about surgical applications of 3D printing from 3D Systems; find out how 3D Hubs is creating a global community by connecting owners of 3D printers with those who want to utilize the technology; and see how Occipital’s 3D scanning hardware for the iPad is supporting patient care. Additionally, they can discover how Artec creates a 3D full-body scan in a mere 12 seconds and enjoy chocolate and candy from the ChefJet food printer.

The session will also feature two Saturday-afternoon panels titled “Diverse Distributed & Design-Driven” and “Innovation Implementation,” with the latter exploring:

…some of the challenges and issues to consider in this brave new world. Will the FDA approve printed food, pharmaceuticals, and medical devices? How can 3D printing startups include patients in their design process? What are the public health implications when almost anyone can print biomaterials from the comfort of their own home? And once we ensure public safety, how can we make 3D printing affordable and accessible for all?

Darrell Hurt, PhD, computational biologist and project lead for the National Institutes of Health 3D Print Exchange, is among the panelists, and Monika Wittig, director and co-founder of Live Architecture Network, will moderate the discussions.

“As a designer, I am thrilled that this conference continues to widen the view of valuable cross-disciplinary collaborations. This is decidedly the aspect that I found most profound during my first Medicine X experience,” said Wittig. “My hope is attendees leave this session feeling a heightened awareness of 3D design and production technologies and the many realms of potential engagement in health sectors including prototyping, globally-distributed production and mass-customized design.”

Video game accessory may help multiple sclerosis patients reduce falls, boost brain connections

Wii_balance_boardNintendo’s Wii Balance Board has helped get people off the couch and moving as they play aerobic video games like Super Hula Hoop or Dance Dance Revolution. Now a study published this week in Radiology shows that the video game console’s balance board may help reduce multiple sclerosis (MS) patients’ risk of falls by rewiring their brains.

In a small study, researchers used an MRI technique called diffusion tensor imaging to analyze changes in the brain of MS patients that used the Wii Balance Board while playing video games for 30-40 minutes a day five days a week.

According to a recent Forbes post:

MRI scans in the MS patients in the study demonstrated significant growth of nerve tracts which are integral in movement as well as balance. It turns out that the changes seen on MRI correlated with improvements in balance as measured by an assessment technique called posturography.

These brain changes in MS patients are likely a manifestation of neural plasticity, or the ability of the brain to adapt and form new connections throughout life, said lead author Luca Prosperini, M.D., Ph.D., from Sapienza University in Rome, Italy.

”The most important finding in this study is that a task-oriented and repetitive training aimed at managing a specific symptom is highly effective and induces brain plasticity.”

“More specifically, the improvements promoted by the Wii balance board can reduce the risk of accidental falls in patients with MS, thereby reducing the risk of fall-related comorbidities like trauma and fractures,”

 added Prosperini.

Researchers cautioned that the improvements in balance did not persist after patients stopped playing the video games, suggesting that patients will need to continue their training in order benefit from the intervention.

Biodesign fellows take on night terrors in children

Biodesign fellows take on night terrors in children

baby on bed

Standing in the Clark Center’s grand courtyard, gazing upward at scientists ascending an outdoor staircase and traversing the exterior corridors on the top two floors, one senses that big ideas take shape here. But how?

Prototyping, say Andy Rink, MD, and Varun Boriah, MS, who spent the last year as Biodesign fellows. Part of Stanford’s Bio-X community, the Biodesign Program trains researchers, clinicians and engineers to be medical-technology innovators during its year-long fellowship. Fellows learn the Biodesign Process, which could be likened to design thinking for health care. On teams of two or four, the fellows identify a substantial health-care need and generate ideas to solve it using medical-device innovation.

Though most Biodesign projects take root after fellows complete a “clinical immersion” shadowing health-care workers in a hospital to observe problems, Rink found his inspiration when visiting family and waking up to a 3-year-old relative’s screams from recurring night terrors. The problem was not so much that it affected the child – pediatricians may advise that children will likely outgrow the condition – but that it affected the parents, Rink saw.  The parent’s lost sleep and anxiety over their child’s well being had huge effects on their quality of life. (In some cases, these are so severe that Xanax and Valium may be prescribed to the children as a last-ditch effort.) What if a treatment could be found that involved no medication and no parental intervention, offering everyone a solid night’s sleep?

The physician and engineer are working with School of Medicine sleep researchers Christian Guilleminault, MD, professor of psychiatry and behavioral sciences, and Shannon Sullivan, MD, clinical assistant professor of psychiatry and behavioral sciences, on a clinical method to treat night terrors in children. In a first-floor room of the Clark Center, they’re protoyping an under-mattress device that senses how deeply a child is sleeping and is able to prevent the nightly episodes from occurring, creating a healthier sleep cycle for the children.  This relieves the parent’s anxiety, and helps the entire family sleep better.

Faculty and students from more than 40 departments across Stanford’s campus, including the schools of medicine, business, law, engineering and humanities and sciences, play a role in Biodesign, as do experts from outside the university. Fellows work closely with the Institute of Design at Stanford, attending – and then teaching – the school’s d.bootcamp. They also have access to the d.school’s facilities and consult regularly with their faculty. Some of the d.school’s methods – focusing on big problems, encouraging radical collaboration, prototyping early and user-testing before focusing on functionality – guide the trajectory of Biodesign projects.

Physicians who are Biodesign fellows often work outside their specialty, and engineers bring a mix of academic and industry experience to the design table. While faculty mentors may simply provide advice to fellows, Guilleminault and Sullivan have become invested in the course of the research as lead investigators on the study. For their involvement, they were both honored with the Biodesign Specialty Team Mentorship Award.

Fellow Boriah noted that medical-device innovation is moving from products like catheters to systems such as health IT, mobile health and software. A former CEO and co-founder of a wearable patient blood-diagnostics device, he said the Biodesign program has provided valuable “access to clinical reality.” Rink, a surgical resident at Northwestern University, said that as a fellow, he’s been “exposed to a side you don’t see in a hospital.”

The researchers are currently recruiting participants ages 2-12 for their study. Rink and Boriah are also working with the Stanford-supported StartX to see their project into the next stage of development.

Stanford-developed eye implant could work with smartphone to improve glaucoma treatments

Stanford-developed eye implant could work with smartphone to improve glaucoma treatments

eyeGlaucoma, caused by rising fluid pressure in the eyes, is known as the silent thief of sight. Catching the disease in the early stages is critical because if detected too late it leads to blindness. Regular monitoring and controlling of the disease once detected is invaluable.

Now, Stephen Quake, PhD, professor of bioengineering at Stanford, and Yossi Mandel, MD, PhD, an applied physics and ophthalmologist at Bar-Ilan University in Israel, have developed a tiny eye implant that would allow patients to take daily or hourly measurements of eye pressure from home.

A recent Stanford Report article explains how the device works:

It consists of a small tube – one end is open to the fluids that fill the eye; the other end is capped with a small bulb filled with gas. As the [internal optic pressure] increases, intraocular fluid is pushed into the tube; the gas pushes back against this flow.

As IOP fluctuates, the meniscus – the barrier between the fluid and the gas – moves back and forth in the tube. Patients could use a custom smartphone app or a wearable technology, such as Google Glass, to snap a photo of the instrument at any time, providing a critical wealth of data that could steer treatment. For instance, in one previous study, researchers found that 24-hour IOP monitoring resulted in a change in treatment in up to 80 percent of patients.

“For me, the charm of this is the simplicity of the device. Glaucoma is a substantial issue in human health. It’s critical to catch things before they go off the rails, because once you go off, you can go blind. If patients could monitor themselves frequently, you might see an improvement in treatments,” Quake added.

Countdown to Medicine X: Specially designed apps to enhance attendees’ conference experience

Countdown to Medicine X: Specially designed apps to enhance attendees’ conference experience

Figure 3 - BlanketLast year’s Stanford Medicine X conference explored ways in which technology could be used to augment the attendees’ experiences. During breaks between sessions, organizers used specially developed software to transform television screens set up in the lobby outside the main auditorium into interactive spaces where participants could exchange ideas. On one screen, attendees used their mobile phones to text their reflections on previous sessions or respond to prompts such as: “What’s your dream for health care?” The texts appeared as yellow sticky notes on a virtual corkboard. Another screen served as a digital journal where participants could text comments about what they learned and have them displayed to a wider audience. As people walked up to the screen to read the contextually relevant content, they naturally started conversations. In an effort to bridge the divide between the people who were physically present at the conference and those who were watching the live-stream from other locations, an additional screen broadcast tweets from around the world in real time.

This year, conference organizers have developed three iPhone apps for Medicine X based on Apple iBeacon, a Bluetooth-powered location system. “When we heard about the iBeacon technology, it was clear that it would fit really well into a conference setting as well as being useful for allowing people to interact with the large-screen displays,” said Michael Fischer, a PhD student in computer science in the MobiSocial Lab at Stanford, who helped develop the app. “We brainstormed all the possible ways that the iBeacon technology could help people participate in the conference and came up with some ideas that we are excited to test out at the upcoming conference.”

In anticipation of this year’s conference, I reached out to Fischer to learn more about how the apps will further enhance attendees’ experience at Medicine X. Below he explains how they will facilitate networking among participants, allow them to provide feedback or rate speakers and serve as a sort of “flight-attendant call button.”

Can you briefly explain how the apps work?

One app allows us to extend the Wellness Room, so that people can request items without having to go to the room and miss part of a session. The Wellness Room provides special amenities, such as warm blankets or a place to rest, to assist patients in managing their conditions during the conference. The room was designed to help patients physically attend the conference who might have otherwise not been able to. For example, a previous ePatient attendee had a medical condition called cryoglobulinemia, which causes proteins known as cryoglobulins to thicken if the ambient temperature drops too low. If this were to occur, it could lead to kidney failure and would be life threatening. So it’s crucial for this patient to keep warm. Using the iBeacon technology we were able to develop a system that allows people to use an iPhone to request a blanket or other item be delivered to their seat. There will be iBeacons on all the tables in the room so that the phone will automatically know where you are sitting. All the requests will be forwarded to a volunteer who will bring the item directly to the table.

Another app will be used during the breaks to help people get to know each other. The application works by displaying short bios on a nearby TV screen. In this way, the screen acts as a type of watering hole that people can gather around. When new people approach, their bios will be added to the screen. When a person leaves the proximity of the screen, the bio will be removed. We’ll have multiple screens set up around the conference. Our hope is that people can find a group that they might not yet be familiar with. The service is opt-in and people can switch to and from stealth mode at any time. Conference-goers will also have the option to forgo this app altogether.

Lastly, we have developed a feature that will be used at check-in. We want to create an experience that will surprise and delight people from the moment they step into the conference. There is a tradition at Stanford during freshman year that when you first come to your dorm, the dorm staff yells out your name. It is pretty big surprise and makes you feel part of the community instantly. We wanted to replicate that experience as best we could for the conference.

Mining Twitter to identify cases of foodborne illness

During this year’s Big Data in Biomedicine conference at Stanford, Taha Kass-Hout, MD, chief health informatics officer for the U.S. Food and Drug Administration, talked about the potential of social media to monitor food safety saying, “You are what you eat, and in this world, you are what you tweet.” Taking this concept into a real-world setting, officials at the Chicago Department of Public Health developed an algorithm to mine Chicago-based tweets for sentiments of food illnesses and, as a result, were able to investigate incidents of food poisoning that would have otherwise gone unnoticed. According to a recent article in Popular Science:

… in a recent project, the city of Chicago sought food poisoning cases by setting an algorithm to mine Chicago-area tweets for complaints. The Chicago Department of Public Health’s Twitter bot, plus a new online complaint form, helped the department identify 133 restaurants for inspections over a 10-month period. Twenty-one of those restaurants failed inspection and 33 passed with “critical or serious” violations. Not a bad haul.

Chicago is now working with the health departments of Boston and New York to see if its system could work in those cities, according to a report city researchers published with the U.S. Centers for Disease Control and Prevention. Plus, Twitter isn’t the only social media platform cities are looking to mine for public health violations. In May, New York City’s department of health reported on using an algorithm to spot Yelp reviews that point to food poisoning cases. New York’s Yelp project led the city to discover three restaurants that had multiple violations. All the Yelp cases the city inspected had otherwise gone unreported, New York officials wrote in their own CDC report.

The Chicago bot was pretty simple, as Twitter-reading computer programs go. It searched for tweets geo-located to Chicago and its surrounding suburbs that mentioned “food poisoning.” Human staff then read the tweets to determine if they were relevant. (Sounds fun.) Staff marked tweets as relevant or not relevant, to give the algorithm data to better learn what tweets to pull in the future. Then staff members responded to relevant tweets themselves.

A Stanford physician shares his experiences creating evidence-based medical apps

iPad_080814A piece published earlier this week on iMedicalApps spotlights the work of Steven Lin, MD, a clinical instructor in family medicine at Stanford who is the co-creator of two evidence-based medical apps. The first app he helped develop was Ilithyia, a point-of-care clinic prenatal app, and the second is L’Allegro, which helps physicians select the appropriate antidepressant for patients. From the piece:

Dr. Lin first thought about creating an app as an intern when he noted the large gap between what he had learned in medical school and what was happening in practice. He had knowledge but it was often difficult translating that knowledge into point of care practice. He first concentrated on prenatal visits as he wanted to find the evidence base for current practice and make that available to himself as well as his fellow interns.

He started with researching guidelines, community standard of care, and even insurance allowances for visits and labs. He then took this information and made a framework of sorts. Each visit had allotted information- labs, guidance, findings, etc, and this framework became the basis for how he organized his app.

Lin and partner, a programmer who was finishing his final year of high school when they started working together, plan to “work with the Society for Teachers in Family Medicine and plans to create a mobile version of their study cases” for third app.

Countdown to Medicine X: How to engage with the “no smartphone” patient

Countdown to Medicine X: How to engage with the "no smartphone" patient

When I saw the full agenda of the upcoming Stanford Medicine X conference, the name of one of the panels – “The ‘No Smartphone’ Patient” -  jumped out at me. The conference is focused on the ways new technology intersects with health care, and it’s heavily attended by researchers, health-care innovators, and patients who strike me as likely to never leave the house without their smartphone or tablet. The topic seemed a curious thing for the organizers to offer.

Once I read the full description of the Sept. 5 talk, though, it made complete sense. Part of Medicine X’s aim has always been to empower patients to be proactive in their care and to contribute to the discussion on how technology can be used to improve human health. So if a significant chunk of the population is low-income and/or has limited access to health-enhancing technologies, it would be prudent for stakeholders to determine how to improve that access and how, exactly, to give those so-called “no smartphone” patients a voice.

Intrigued by the topic and wanting a preview of the discussion, I reached out to panelist Veenu Aulakh, executive director of the Center for Care Innovation (CCI), which develops patient-engagement innovations and provides support to the state’s safety-net providers (community health centers, public hospitals, and public health clinics). After noting that almost one-third of California’s population is considered underserved and vulnerable, Aulakh talked with me about what’s been done for underserved populations in recent years, how she believes the digital divide among various populations is shrinking, and what those attending “The ‘No Smartphone’ Patient” panel can expect to learn.

At Medicine X, you’ll be discussing some of the cultural, social, and economic barriers that prevent certain patients from fully engaging with health-enhancing technologies. Can you provide a hint of what those things might be?

There are a number of barriers for patients to fully engage with health-enhancing technologies. The solutions that are created today are often not built for low-literacy, non-English speaking patients. Having solutions in Spanish and written at less than a 4th grade reading level are critical for getting solutions adopted. In addition, many of these technologies are often introduced to patients via their health-care providers, and the solutions are not created at a price point that either safety net health systems or patients can afford. Also, the solutions need to be more reflective of the realities of patients lives – folks are extremely busy and don’t have a lot of time to hand-enter data or engage with technologies that don’t provide immediate value. If we’re going to get patients (and their providers) to use effective technologies, we need to make sure that they can see immediate benefits if they are to use these technologies regularly. Lastly, the smartphone penetration rate in low-income populations still isn’t at a level where it would be useful for most safety net providers to broadly offer smartphone solutions to their patients. As this changes, the adoption rate of health apps and similar technologies may rise as well.

Do you foresee a time when patients who currently face such barriers can become part of the e-patient movement?

I think there are already many vulnerable and underserved people who would consider themselves part of the e-patient movement. Health centers are now beginning to e-mail with patients, inviting them to participate in texting programs and starting to roll out other e-offerings. However, for more patients to join the e-patient movement, we need to reduce the barriers. As more patients move to smartphones, I believe we’ll see a shrinking of the digital divide. According to Pew Research Center, as of January 2014, 47 percent of low-income people had smartphones. As this number continues to increase, this will help low-income patients be active e-patients (assuming language, literacy and cost issues are addressed).

CCI works to bring various health-enhancing technologies to California’s low-income patients. What are some of the patient-engagement techniques you’ve seen delivered in recent years?

We’ve seen everything from building strong patient and family advisory groups who give input to clinics on how to better design care systems that are truly patient-centered, to launching efforts to hear from the patients about their needs through surveys, focus groups and ethnographic research. Many clinics are also starting to implement texting programs to follow up with patients between visits with appointment reminders, or send education reminders for patients with chronic diseases. They’re also starting to use remote monitoring devices like home blood pressure and blood glucose monitoring. The funding environment (and the limited resources of both clinics and patients) have hampered wide-spread adoption of these types of solutions, but clinics definitely see the value in engaging patients – with both high- and low-tech solutions.

How have your group and other safety-net providers involved patients in developing these techniques?

Many health centers have developed patient and family advisory groups to provide feedback to design these programs. Other clinics are beginning to use the principles of design thinking to better understand the needs of their patients and going beyond the traditional patient experience surveys to hear the real voice of their patients. However, much more work needs to be done to make this the standard of care.

NPR highlights Google’s Baseline Study and what it might teach us about human health

NPR highlights Google's Baseline Study and what it might teach us about human health

Late last month, my colleague reported on Stanford partnering with Google [x] and Duke on a research study to better understand the human body. On the most recent edition of NPR’s Science Friday, project collaborator Sanjiv Sam Gambhir, MD, PhD, professor of radiology at Stanford, discussed the project and joined Jason Moore, MD, professor of genetics at Dartmouth College, in a segment called “Will big data answer big questions on health?”

According to Gambhir, what makes the new project unique is the focus on understanding the baseline of healthy human beings. Will it ultimately yield meaningful data about what makes us healthy? Listen here for the researchers’ thoughts.
