Imagine sitting across from your doctor.
He's speaking to you, but you can't hear him clearly. There's a large black smudge where his face should be, so you're unable to really read his lips. What he's saying is important, so you lean in. But you're frustrated as you struggle to understand what's going on.
You're experiencing life through the eyes of a 74-year-old patient named Alfred -- seven minutes in the shoes of an elderly man whose audiovisual impairments are misdiagnosed as cognitive ones -- and a story that students across many disciplines have worked together to create.
A virtual reality experience transforms the user into a 74-year-old named Alfred in order to see his perspective as a medical patient.
"[We're] trying to portray different kinds of medical conditions, sensory changes from the first-person perspective of a patient," said Carrie Shaw, a master's student in biomedical visualization and content creator of the case study titled, "We Are Alfred." The project was the focus of Shaw's research this year. It won first place in the Art/Design/Humanities & Social Sciences Category among graduate student projects at the UIC Research Forum, as well as the Vesalius Trust Scholarship Award.
Their goal was to craft an interactive, experiential product that could be used for curriculum in geriatrics -- the health and care of elderly people -- because of predicted growth in future U.S. aging populations and a disconnect between patients and the students or doctors who treat them.
"[Medical students] are usually in their early 20s and not experiencing those kinds of challenges yet, so we decided to create something that would give them the experience of what it might be like to go through the aging process," Shaw said.
Users experience that with some headphones and the Oculus Rift Development Kit 2, a headset that can immerse them into a 360-degree virtual reality experience. The headset also includes a Leap Motion device that tracks and projects user's hands in the story to make them feel like they're Alfred.
Becoming Alfred helps users empathize with and better understand elderly patients.
"The project is focusing on comfort," said Eric Swirsky, clinical assistant professor of biomedical and health information sciences and a faculty adviser for the project. "It's not curing, it's not curative, it's not even treatment-oriented. It's about comforting and understanding where the patient is so that you can be with him."
The group started with Alfred .5, the first iteration of the project. The prototype had a completely virtual environment. But after tests, trials, discussion and input from expert geriatricians, the second iteration was refocused to include graphic elements, real people and live scenes -- a redesigned interactive cinema on an almost zero-dollar budget.
"[Interactive cinema] is a kind of marriage of directing for film and directing for theater because you're directing a 360-degree space where the user has the freedom to look wherever they want," said the film's director, Ryan Lebar, a student collaborator from the University of North Carolina School of the Arts.
The live-action story includes six scenes: "Happy Birthday Song," "Day Dream," "Wine Spill," "Waiting Room," "Taking the Cognitive Test" and "Follow Up With the Doctor."
UIC engineering students Thomas Leahy and Jakub Borowski used programming techniques and development tools to stitch together footage and add simulations of medical issues such as severe macular degeneration or hearing loss. "There were a lot of different, new technologies that we were trying to integrate together, and I think that was one of the biggest themes of our whole project," said Leahy.
The group did a lot of troubleshooting and used each others' expertise and ideas to solve problems and tackle challenges.
"I think there's just so much strength in diversity," Shaw said. "It speaks to the complexity of life. If you work in one discipline, it's easy to focus in on that one thing, working with yourself, but if you can balance working across a group of people with different ideas and perspectives, what you create winds up looking a little bit more like the things we actually have to deal with in the world."
"They're in the forefront saying, 'Hey this technology is here and we could be doing more with it,'" added Leah Lebowicz, adviser chair for the project and clinical assistant professor for the biomedical visualization program.
"And when we -- people across many disciplines with different expertise -- all get together, we can produce some amazing things. I think that's what made this project so successful."
Other project collaborators included Yoobin Cha, a graduate student in communication; computer science grad students Karen Corda and Abhishek Tripathi; and faculty member Rachel Yudkowsky, associate professor of medical education.

ADHD DRUG CAUSES CARDIAC ARREST 

Use of methylphenidate in children and young people with ADHD is associated with a slightly increased risk of abnormal heart rhythm (arrhythmia) shortly after the start of treatment, suggests research published by The BMJ today.


Though the absolute risk is likely to be low, the researchers say the benefits of methylphenidate "should be carefully weighed against the potential cardiovascular risks of these drugs in children and adolescents."
Methylphenidate is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD), and narcolepsy. It is sold under various trade names, Ritalin being one of the most commonly known.
The cardiac safety of stimulants, which are known to slightly raise blood pressure and accelerate the heart rate, has been hotly debated, but the evidence is conflicting.
So a team of researchers based in Australia, Canada and South Korea set out to measure the cardiac safety of methylphenidate in children and young people with ADHD.
Using the South Korea National Health Insurance Database, they extracted data on 1,224 cHildren and 
cardiac events from a population of 114,647 children and young people aged 17.

Cardiac events included heart rhythm problems (arrhythmias), high blood pressure heart attacks (myocardial infarction), ischemic stroke, and heart failure.

Cases of arrhythmia were statistically significantly more likely to have occurred during the first two months of use compared with periods of non-use, and risk was highest in the first three days of use.
The risk was more pronounced in children with existing congenital heart disease

significant risk of myocardial infarction was observed, though risk increased after the first week of treatment and remained raised for the first two months of continuous treatment.
No increased risk was observed for hypertension, ischemic stroke, or heart failure.
The authors point out that this is an observational study so no firm conclusions can be drawn about cause and effect -- and that their findings should be interpreted with caution. However, the results prompt them to suggest that methylphenidate use might "trigger" the occurrence of arrhythmia in individual patients.
"Methylphenidate exposure in children and young people with diagnosis of ADHD is associated with arrhythmia and potentially with myocardial infarction in specific time periods of use," they write. "With the increased use of drugs for ADHD globally, the benefits of methylphenidate should be carefully weighed against the potential cardiovascular risks of these drugs in children and adolescents."
In a linked editorial, John Jackson, a research fellow at Harvard School of Public Health in Boston, says it is difficult to describe the absolute risk in this type of study, but in the average child, the risk of serious cardiovascular events is extremely small (3 per 100,000 per year) and any absolute increase associated with methylphenidate is also likely to be small.
And he points out that regulatory labeling and treatment guidelines for stimulants recommend caution using these drugs in children with personal or familial history of cardiovascular disease and call for routine monitoring of blood pressure.
"This study underscores the need to consider the severity of ADHD symptoms and the option of non-stimulants for children with high cardiovascular risk and to closely monitor patients for whom stimulants are critical for their wellbeing and development," he concludes.

Genetic risk for type 1 diabetes driven by faulty cell recycling


FULL STORY


Researcher Scott Soleimanpour, M.D., who lives with type 1 diabetes, publishes findings about faulty cell recycling that disrupts the ability of beta cells to regulate blood sugar.

Researchers, tackling a modern challenge of diabetes research, have identified a gene believed to disrupt the ability of beta cells to produce insulin resulting in type 1 diabetes.
The loss of beta cell function may be driven by a defect in Clec16a, a gene responsible for getting rid of old mitochondria, the powerhouses of cells, and making room for fresh ones. Healthy mitochondria are crucial to allowing beta cells to produce insulin and control blood sugar levels.
Little has been known about the ways in which many diabetes genes work, but a study published in the journal Cell sheds light on a genetic risk component of type 1 diabetes and a new approach for keeping beta cells strong.
"Preserving beta cells is the top priority in diabetes care," says lead author Scott Soleimanpour, M.D., investigator at the University of Michigan's Brehm Diabetes Research Center. "This new pathway will allow us to focus therapies on preserving healthy mitochondria within the beta cell to treat or prevent both type 1 and type 2 diabetes."
Soleimanpour, an endocrinologist who treats patients at the University of Michigan Health System, has lived with type 1 diabetes for 30 years.
He's made a career of studying diabetes, including a fellowship at Perelman School of Medicine at the University of Pennsylvania where his laboratory work to understand Clec16a began.
Type 1 diabetes is the unpreventable form of diabetes that usually strikes children and young adults. It's less common than type 2 diabetes which is associated with older age and obesity.
Diabetes is diagnosed when the body has an abnormally high level of glucose, or blood sugar. It's believed that in type 1 diabetes, the body's immune system destroys the pancreatic beta cells responsible for making insulin, a hormone the body needs to convert food into energy.
But that model may be changing after studying Clec16a mutations in both animal and human beta cells.
"Scientists are starting to appreciate the importance of beta cells in understanding why type 1 diabetes occurs," says Soleimanpour, a U-M assistant professor of medicine. "Rather than innocent bystanders to a malfunctioning immune system, our research shows beta cells are central players in the disease itself."
