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.

Study shows number of American teens using sunscreen is declining

7755295064_9c253c9b91_zDespite an increase in cases of melanoma, the most dangerous type of skin cancer, growing percentage of high school students get a failing grade when it comes to using sunscreen. HealthDay reports:

The number of U.S. teens using sunscreen dropped nearly 12 percent in the last decade, a new report shows.

During that same time period, the number of teens using indoor tanning beds barely decreased. Both indoor tanning and failure to use sunscreen increase the risk of skin cancers, including deadly melanomas, the researchers noted.

“Unfortunately, we found a decrease in the overall percentage of teens who reported wearing sunscreen, from 67.7 percent in 2001 to 56.1 percent in 2011,” said lead researcher Corey Basch, an associate professor in the department of public health at William Paterson University in Wayne, N.J.

“Using sun-protective behaviors like applying sunscreen and avoiding intentional exposure to tanning devices will be key [to lowering cancer risk],” she added.

Use of indoor tanning devices by white girls decreased only slightly, from 37 percent in 2009 to 29 percent in 2011, she said.

Study authors say more research is need to understand why teens aren’t following national guidelines regarding sun protection.

Study shows poor sleep habits as a teenager can “stack the deck against you for obesity later in life”

Study shows poor sleep habits as a teenager can "stack the deck against you for obesity later in life"

11386276_c148dfd9bd_zNew research examining the effect of sleeplessness on weight gain in teenagers over time offers strong evidence that inadequate sleep may increase the risk of obesity.

In the study, researchers at Columbia University and the University of North Carolina pored over health information from the the National Longitudinal Study of Adolescent Health on more than 10,000 Americans ages 16 and 21. In addition, details about individuals’ height, weight and sleep habits were collected during home visits in 1995 and 2001.  According to a release, results showed:

Nearly one-fifth of the 16-year-olds reported getting less than six hours of sleep. This group was 20 percent more likely to be obese by age 21, compared to their peers who got more than eight hours of sleep. While lack of physical activity and time spent watching television contributed to obesity, they did not account for the relationship between sleeplessness and obesity.

“Lack of sleep in your teenage years can stack the deck against you for obesity later in life,” says [Columbia researcher Shakira Suglia, ScD]. “Once you’re an obese adult, it is much harder to lose weight and keep it off. And the longer you are obese, the greater your risk for health problems like heart disease, diabetes, and cancer.”

“The message for parents is to make sure their teenagers get more than eight hours a night,” adds Suglia. “A good night’s sleep does more than help them stay alert in school. It helps them grow into healthy adults.”

Regularly practicing hatha yoga may improve brain function for older adults

77878_webPast studies have suggested that practicing yoga can help those suffering from insomnia rest easier and boost the immune system. Now new research shows that regularly participating in hatha yoga, which emphasizes physical postures and breath control, may improve older adults’ cognitive function.

In a study (subscription required) involving more than 100 adults ages 55 to 79, researchers assigned roughly half of the individuals to attend hatha yoga classes three times a week for eight weeks while the others participated in sessions in which they engaged in stretching and toning exercises. The Huffington Post reports:

At the end of eight weeks, the group that did yoga three times a week performed better on cognitive tests than it had before the start of yoga classes.

The group that did stretching and toning displayed no significant change in cognitive performance over time. In addition, researchers say the differences seen between the groups were not the result of age, gender, social status or other similar factors.



Edward McAuley
, PhD, who co-led the study, noted that participants in the yoga group displayed significant improvements in working memory capacity. “They were also able to perform the task at hand quickly and accurately, without getting distracted,” he said in a press release. “These mental functions are relevant to our everyday functioning, as we multitask and plan our day-to-day activities.”

Why memories of mistakes may speed up learning

Why memories of mistakes may speed up learning

mistake_learningRemember when you burnt the crab cakes on one side while testing a new recipe for a dinner party and had to compensate by generously dressing them with a creamy sauce? What about the time you were introduced to a friend’s new girlfriend, whose name was somewhat similar to the last one, and you called her the wrong name? Or that accidental trip down a one-way street while in an unfamiliar city? Chances are you didn’t make these mistakes twice.

Now findings (subscription required) published today in Science Express may explain how memories of past errors speed learning of subsequent similar tasks. As explained in a release, scientists have known that when performing a task, the brain records small differences between expectation and reality and uses this information to improve next time. For example, if you’re learning how to drive a car the first time you may press down on the accelerator harder than necessary when shifting from the break pedal. Your brain notes this and next time you press down with a lighter touch. The scientific term for this is “prediction errors,” and the process of learning is largely unconscious. What’s surprising about this latest study is “that not only do such errors train the brain to better perform a specific task, but they also teach it how to learn faster from errors, even when those errors are encountered in a completely different task. In this way, the brain can generalize from one task to another by keeping a memory of the errors.”

To arrive at this conclusion, researchers used a  simple set of experiments where volunteers were placed in front of joystick that was hidden under a screen. More from the release:

Volunteers couldn’t see the joystick, but it was represented on the screen as a blue dot. A target was represented by a red dot, and as volunteers moved the joystick toward it, the blue dot could be programmed to move slightly off-kilter from where they pointed it, creating an error. Participants then adjusted their movement to compensate for the off-kilter movement and, after a few more trials, smoothly guided the joystick to its target. In the study, the movement of the blue dot was rotated to the left or the right by larger or smaller amounts until it was a full 30 degrees off from the joystick’s movement. The research team found that volunteers responded more quickly to smaller errors that pushed them consistently in one direction and less to larger errors and those that went in the opposite direction of other feedback.

Daofen Chen, PhD, a program director at the National Institute of Neurological Disorders and Stroke, commented on the significance of the findings saying, “This study represents a significant step toward understanding how we learn a motor skill … The results may improve movement rehabilitation strategies for the many who have suffered strokes and other neuromotor injuries.”

Biosecurity experts discuss Ebola and related public health concerns and policy implications

Biosecurity experts discuss Ebola and related public health concerns and policy implications

ebola_081214

More than 1,800 people in the West African nations of Liberia, Sierra Leone and Guinea have contracted the Ebola virus since March and the death toll has surpassed 1,000, according to the latest figures from the World Health Organization. As the number of cases and death continue to climb many are concerned about what can be done to curtail the outbreak and the likelihood of it spreading to the United States.

In a Q&A recently published by the Center for International Security and Cooperation and The Freeman Spogli Institute for International Studies, Stanford biosecurity experts David Relman, MD, and Megan Palmer jointly answer these questions and others related to the public health concerns and policy implications if the outbreak. On the topic of broader lessons about the dynamics and ecology of emerging infectious diseases that can help prevent or respond to outbreaks now and in the future, they respond:

These latest outbreaks remind us that potential pathogens are circulating, replicating and evolving in the environment all the time, and human action can have an immense impact on the emergence and spread of infectious disease.

We are starting to see common factors that may be contributing to the frequency and severity of outbreaks. Increasing human intrusion into zoonotic disease reservoir habitats and natural ecosystems, increasing imbalance and instability at the human-animal-vector interface, and more human population displacement all are likely to increase the chance of outbreaks like Ebola.

The epicenter of this latest outbreak was Guéckédou, a village near the Guinean Forest Region. The forest there has been routinely exploited, logged, and neglected over the years, leading to an abysmal ecological status quo. This, in combination with the influx of refugees from conflicts in Guinea, Liberia, Sierra Leone, and Cote d’Ivoire, has compounded the ecological issues in the area, potentially facilitating the spread of Ebola. There seems to be a strong relationship between ecological health and the spread of disease, and this latest outbreak is no exception.

While forensic analyses are ongoing, unregulated food and animal trade in general is also a key factor in the spread of infectious diseases across large geographic regions. Some studies suggest that trade of primates, including great apes, and other animals such as bats, may be responsible for transit of this Ebola strain from Central to Western Africa.

Overall, Relman and Palmer remind the public, “It’s important that we not lose sight of more chronic, but less headline-grabbing diseases that will be pervasive, insidious long-standing challenges for Africa and elsewhere.”

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.

Pediatric patients create vibrant mural with help from Hewlett-Packard and DreamWorks Animation

Here’s a feel-good story that will lift your spirits. Over at Lucile Packard Children’s Hospital Stanford, patients are working with volunteers from Hewlett-Packard and DreamWorks Animation to construct a unique piece of artwork designed digitally or drawn by hand. As described in the above video, the DreamWorks team worked with children in the hospital’s onsite school to create imaginary creatures, and next built a background and composited the patients’ art into a large mural. Then, Hewlett-Packard printed the custom designs onto PVC-free wallpaper. The final mural now hangs in Hewlett-Packard’s Palo Alto headquarters.
