Biodesign fellows take on night terrors in children

Biodesign fellows take on night terrors in children

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 researchers address hunger in new book on food security

Stanford researchers address hunger in new book on food security

riceA piece from Stanford’s Freeman Spogli Institute for International Studies notes how experts across campus are working together to address the complex global problem of hunger. A new book, The Evolving Sphere of Food Security (Oxford University Press, August), discusses the problem from numerous perspectives, including medicine, in its 14 chapters. The book’s editor, Rosamond Naylor, PhD, is director of the Center on Food Security and the Environment, which is housed jointly within the FSI and the Woods Institute for the Environment.

From the piece:

“This book grew out of a recognition by Stanford scholars that food security is tied to security of many other kinds,” said Naylor, who is also William Wrigley Senior Fellow at the Freeman Spogli Institute for International Studies and the Stanford Woods Institute for the Environment. “Food security has clear connections with energy, water, health, the environment and national security, and you can’t tackle just one of those pieces.”

Stanford has a long history of fostering cross-disciplinary work on global issues. It is in this spirit that the idea for the book was born, Naylor said. The book weaves together the expertise of authors from the fields of medicine, political science, engineering, law, economics and climate science.

A recurring theme throughout the book – also reflected in its title – is the evolving nature of the food security challenges countries face as they move through stages of economic growth. At low levels of development, countries struggle to meet people’s basic needs. For example, Naylor’s chapter on health, co-authored with Eran Bendavid [MD] (medicine), Jenna Davis [PhD] and Amy Pickering [PhD] (civil and environmental engineering), describes a recent study showing that poor nutrition and rampant disease in rural Kenya is closely tied to contaminated, untreated drinking water. Addressing these essential health and sanitation issues is a key first step toward food security for the poorest countries.

Exercise and relaxation techniques may help ease social anxiety, study finds

Exercise and relaxation techniques may help ease social anxiety, study finds

TrishWardMeditationPicPhysical exercise and relaxation techniques are common forms of stress-relief. Now, a new study has found that both may help people with social anxiety perceive their surroundings as less threatening environments.

Researchers from Queen’s University in the U.K. conducted two experiments measuring anxiety in participants. In both experiments, the participants were shown point-of-light displays describing a human but not indicating which way the stick figure was facing or whether it appeared to be approaching or receding. Facing-the-viewer bias, a possible biological protective mechanism, may lead people to assume the figure is approaching and posing a threat. And, according to the study, people who are more anxious may place their attention on more threatening stimuli, thereby increasing anxiety.

The researchers tested two means of altering participants’ perception of threat when looking at the stick-figure displays. From a release:

“We wanted to examine whether people would perceive their environment as less threatening after engaging in physical exercise or after doing a relaxation technique that is similar to the breathing exercises in yoga (called progressive muscle relaxation),” researcher [Adam Heenan, a PhD candidate,] said in a statement. “We found that people who either walked or jogged on a treadmill for 10 minutes perceived these ambiguous figures as facing towards them (the observer) less often than those who simply stood on the treadmill. The same was true when people performed progressive muscle relaxation.”

“This is a big development because it helps to explain why exercising and relaxation techniques have been successful in treating and mood and anxiety disorders in the past,” Heenan said.

The research was published in PLOS ONE.

"Happy Meal ban": Where are we now?

"Happy Meal ban": Where are we now?

MuppetBabiesA newly released Centers for Disease Control report of a study conducted at Stanford has examined the effects of San Francisco’s 2010 “Happy Meal ban.” The ban prohibited the free distribution of toys with unhealthy meals; the fast-food restaurants McDonald’s and Burger King instead sold the toys for 10 cents. Though neither restaurant complied with the ordinance’s specific calls for changes in nutritional content, improvements have been made.

As reported by SFGate.com:

…over the study’s two-year period, McDonald’s in particular made big changes to its Happy Meals, said [Jennifer Otten, MD,] of the University of Washington School of Public Health — first in California, then nationally.

The fast food giant cut the amount of French fries it serves in Happy Meals in half, replacing them with apples; stopped serving caramel sauce with apples; and began offering nonfat chocolate milk to customers. Otten said those substitutions were “pretty dramatic,” — they reduced the calories in a Happy Meal by 110, and cut the sodium and fat content of the meal as well.

Otten and her colleagues, including senior author Abby King, PhD, concluded in the study, “Although the changes…  did not appear to be directly in response to the ordinance, the transition to a more healthful beverage and default side dish was consistent with the intent of the ordinance. Study results… suggest that public policies may contribute to positive restaurant changes.”

Free, one-minute HIV testing...while you shop for clothes?

outoftheclosetPerhaps you’re familiar with cafe-laundromats or sushi restaurants with tap dancing. But did you ever visit a second-hand clothing and furniture store to take care of your health-care needs? An audio segment and post on the KERA News (Dallas) blog features a local Out of the Closet shop with a free HIV testing site, and soon a community pharmacy, inside their thrift store – making it the 22nd branch of the U.S. chain to have both.

Bret Camp, the Texas regional director of the AIDS Healthcare Foundation, which operates the thrift stores, said in the post, “Our pharmacy will have everything from blood pressure meds to diabetes supplies…How many places can you go and look at jeans while you’re waiting for your medication?”

More from the post:

It’s an innovative idea, says [Douglas Owens, MD,] a professor of medicine at Stanford University who also serves on the U.S. Preventive Services Task Force.

A number of organizations, including the CDC and U.S. Preventive Services Task Force recommended universal HIV testing. Of course testing is only the first step, Owens says.

“When people get an adequate treatment for HIV, the drugs reduce their infectivity and so treatment for HIV not only benefits the person who has HIV; it also provides a very important public health benefit that reduces transmission,” Owens explains in the audio segment.

Stanford med student discusses his documentary on LGBT vets' health

Stanford med student discusses his documentary on LGBT vets' health

doublelifeWhen Stanford anesthesiologist Audrey Shafer, MD, welcomed attendees to a screening of “The Camouflage Closet” on campus recently, she noted the artistic accomplishments and service work of the film’s director, Michael Nedelman. (And also mentioned he was “a Stanford medical student in his spare time.”) Nedelman, who will be entering his third year here, conducted a project with nine LGBT veterans, all patients at the Veterans Affairs Palo Alto Health Care System, exploring their experiences of trauma and recovery.

Nedelman and his collaborators engaged in a community-based participatory method of film-making, allowing participants to tell their stories through art as a path toward empowerment. The participants were provided with cameras to document their stories; they also had a say in the editing process. And while the project was neither officially sanctioned research nor therapy, many of the participants found the process therapeutic. Christine Stout-Holmes said this in the film about sharing her story:

It’s healing. It makes me feel like, “Hey, I don’t have to be agoraphobic.” “Hey, I don’t have to isolate.”

Of course, I feel fists beating me on my back, but I know that that’s not now. And I know that what I’m doing now is going to benefit clinicians, and vets, and hopefully artists, and young girls to know that every story is important.

Since the film’s premiere last June, it has screened at the National Queer Arts Festival, the 31st annual Gay and Lesbian Medical Association conference, and at universities, film festivals and VA hospitals across the U.S. and in Mexico.

Below, Nedelman answers questions about his work.

You have a BA in film studies from Yale. How did you decide to attend med school, and have your interests in art and medicine always intersected?

It took me a while to understand exactly how my interests in art and medicine intersected, but it turned out they had a common ancestor in my love of story.

A few years out of college, I was working at Mount Sinai in New York City on both clinical research and documentary film studies. Whether or not there was a camera in the room, I loved hearing people’s stories, and turning those stories into something meaningful. But in a medical context, I also saw the opportunity to get involved in these stories – to reach past the lens and make a tangible difference.

Combining the two wasn’t really a new concept, though. My first major work in college was a photography project addressing preventable blindness in South India. As with “The Camouflage Closet,” I loaned out cameras to rural vision clinic patients who were able to document their restored sight through images that were important to them. But I had no idea that hyphenating doctor-filmmaker was even an option until I discovered, and later met with, filmmakers like Maren Grainger-Monsen, MD, and Gretchen Berland, MD. Something clicked when I figured out that patient care and digital media could go hand-in-hand.

What are some of the issues faced by this population that you’re most interested in exploring through storytelling?

Some of the issues I found most compelling are not just the unique challenges faced by some individuals (e.g. witch hunts of the pre-DADT – “Don’t Ask, Don’t Tell” – era, increased rates of military sexual trauma, barriers to accessing care), but also the creativity and strength that come from their recovery narratives. Alongside some of the heavier moments in the film, there’s some humor, too. I think I personally learned a lot from the veterans’ resilience, and how their pride – for being LGBT, and for being veterans – factors into their personal growth.

What do you hope viewers will take away from your film?

I hope viewers will come out of the film with a desire to learn more about the unique challenges, types of trauma, and sources of resilience among a previously silenced community. I think there’s a lot to identify with in the film, whether or not you identify as LGBT or a veteran, and there’s a lot to be said for turning empathy into action. This is partly why we also created an accompanying educational resource that summarizes previous research, evidence-based suggestions for culturally relevant care, and resources for clinicians and veterans.

The veterans were excited that clinicians and providers would see and learn from their work. But at the end of the day, I wonder if some of them might have answered this question a little differently. Something we often heard among the vets was, “Even if just one other veteran out there sees this and knows they aren’t alone, we’ve accomplished what we came here to do.”

Physicians more likely to become organ donors, Canadian study finds

Physicians more likely to become organ donors, Canadian study finds

When receiving advice from a physician, one might wonder what the doctor would choose for him- or herself. Recently we discussed here a study on doctors’ preferences for their own end-of-life care. Now, a study published in the Journal of the American Medical Association has reported on physicians’ views and behavior surrounding their own organ donation.

As a news@JAMA piece reports on the Canadian study, physicians are nearly 50 percent more likely than non-physicians to register as an organ donor. More from the piece:

Despite waiting lists for organs in many countries, the percentage of individuals registered in national organ donation registries in most countries is below 40%. The United States fares a bit better than average, with 48% of adults registered as organ donors.

Concerns about organ donation have led to lower-than-average rates of registration in Ontario, Canada, where only about 25% of adults have registered. Currently, there are more than 1500 people on transplant waiting lists in Ontario.

Study author Alvin Ho-ting Li, BHSc, a PhD candidate at Western University in Ontario, Canada, discusses the study’s purpose and findings further in a Q&A section of the piece.

Where is the love? A discussion of nutrition, health and repairing our relationship with food

Where is the love? A discussion of nutrition, health and repairing our relationship with food

Maya Adam, MD, a lecturer on child health and nutrition in Stanford’s Program in Human Biology, associates food with love. “Through food, we learn about where we come from, who we are, and in many ways who we want to be,” she said in a recent TEDxStanford talk. But, as in human relationships involving love, our encounters with food may involve fighting – and even tragedy and betrayal, she noted. She pointed to an antacid commercial’s presentation of a “food fight” between foods we consume to taste but that cause us indigestion and larger health problems over time.

Early in her medical training, Adam said, she learned that “pain is a protective sensation; it helps us to avoid things that could cause damage to our bodies.” Ignoring pain or masking it with antacids, as the ad suggests, sends the message that “we should medicate that sensation away and continue consuming the foods that are hurting us.” What’s more, she said, a cultural “war on food” is depleting our time, energy and joy around eating, all in the midst of an obesity epidemic.

In her talk, Adam, who teaches a massive open online course called “Child Nutrition and Cooking,” recommends examining our modern-day relationship with food, which has grown distant. Regaining a healthy relationship involves learning where food comes from and what’s inside it, and taking care to prepare and cook real food for yourself and loved ones, she said: “May the foods you eat be worthy of you, and may they be made with love.”

Internships expose local high-schoolers to STEM careers and academic life

Internships expose local high-schoolers to STEM careers and academic life

beakersIt’s summertime: Do you know where your teenagers are? A piece in the Palo Alto Weekly discusses some of the choice science internships available to local high-school students at Stanford and other universities in the region. Shadowing scientists in the lab and even contributing to research, the young interns learn real-world applications for subjects they learn in school. They also gain work experience and exposure to academic careers in STEM fields. And a high-profile internship couldn’t hurt to include on college applications.

From the piece:

Coordinators often have to sift through hundreds of applications from students applying from all over the country and internationally. One of the most sought after is the Stanford Institutes of Medicine Summer Research Program, which alone received about 1,400 applications this year to fill about 70 to 75 openings. Decisions are based on academic grounds to help narrow down the number of prospective candidates — a tough task in a pool of extremely well-educated candidates.

But coordinators also recognize the need to provide opportunities for students who don’t have the chance to join accelerated science programs and express that oftentimes the most important quality of an applicant is a passion for science.

The article notes that internships gained through family and friend connections can be unevenly distributed, and  how programs like Stanford’s Raising Interest in Science and Engineering (RISE) Summer Internship Program have made the experiences more accessible. More from the piece:

“Typically those are kids with very educated parents who speak fluent English and who are comfortable poking around Stanford a little bit … or have a network and know somebody who works in a lab here. The RISE students typically just don’t have family members that can help them in that way,” [Kate Storm] says. “I think it’s important to serve all students, not just the privileged gifted students who are going to thrive and do well no matter what because they’ve got the backing of their school and parents and siblings.”

These types of opportunities are important to start curbing the racial disparities that exist in STEM occupations. Roughly 70 percent of the people in STEM occupations were Caucasian, 14 percent Asian, 6.5 percent Hispanic and 6.4 percent African American, according to an American Community Survey Report from the U.S. Census Bureau in 2011. Since 2008, Storm says about 80 percent of RISE graduates have gone on to major in math, engineering or science in college.

Researchers are also passionate about increasing the number of girls in labs since women are also largely underrepresented in STEM fields. The same 2011 U.S. Census Bureau report stated that roughly 25.8 percent of those in STEM occupations are women, compared to 45.7 percent of all jobs.
