Take Two of These…and a Sandwich

“Take medication on an empty stomach.” Patients dread seeing this warning on their pill bottles, knowing that it often means skipped meals and hungry rumbles in the hours before and after taking their medicine. The rationale for the empty stomach is to avoid the unpredictable effects of food on drug metabolism — depending on what you’ve eaten, different amounts of the medication can be absorbed into the bloodstream. But a new clinical trial at the University of Chicago Medicine is testing whether just the right mixture of food and drug could be more convenient for patients while saving a whole lot of money.

Abiraterone (trade named Zytiga), is a drug prescribed to men with castration-resistant prostate cancer. It also is more sensitive to food’s effects than any other marketed drug that is labeled to be taken on an empty stomach. Five times as much of the drug is taken up with a low-fat meal as on an empty stomach, and up to 10 times as much with a high-fat meal. Yet patients are told not to eat for two hours before and for one hour after taking their pills. As a result, taking Zytiga as directed means the amount of the drug absorbed by the body to fight cancer is decreased by 80 to 90 percent.

“This clinical trial is designed to assess the risks and benefits of taking this effective but costly drug with food,” said Russell Szmulewitz, assistant professor of medicine at the University of Chicago Medicine and director of the study. “Taking one pill with a meal, rather than four pills on a empty stomach, is much more convenient for patients, so it may improve compliance. It would also reduce the cost.”

The savings to patients and their insurance companies from taking lower doses of the drug would be significant, since the drug costs $5,000 a month.

“By taking one-fourth of the dose with a low-fat breakfast,” Szmulewitz said, “patients may be able to get the full medical benefit and save about $3,750 per month.”

The convenience would also appeal to patients. Many dislike having to fast for hours before and after taking their medication, which can upset an empty stomach. Since patients with advanced prostate cancer tend to be older, most take multiple medications for additional health issues, fitting each medication into a complicated daily routine. Many patients who take Zytiga wake up during the night, for example, to take the medicine, then go back to sleep, allowing them to eat soon after they wake up.

Texting: A Doctor in Your Pocket?

Posted at 12:38 pm CT on November 21, 2011

textingTexting has grown from technological fad to a primary route of communication popular around the world. With cell phones in the pockets of people of all incomes and ages, the quick, no-frills conversations enabled by texting have made almost everyone more proficient with their thumbs. Due to such impressive ubiquity, people in health care are starting to ask whether text-messaging can be harnessed as a cheap and user-friendly tool for communicating with patients outside of the clinic - particularly hard-to-reach patients in urban and low income areas.

“People are ignoring that unlike every other technology, mobile phones reverse the digital divide,” said Shantanu Nundy, clinical instructor of medicine at the University of Chicago Medical Center. “More low income patients are using phones for text messaging and internet than other groups. So shouldn’t we then be developing technology for this type of population?”

Nundy and Jonathan Dick, a Pritzker graduate now in residency at Columbia University Medical Center, arrived independently at this same idea after separate trips overseas, where they saw clinics in Uganda and India using text messages as part of their operation. With texts, physicians could follow up with patients with chronic diseases, making sure they were taking medications and doing the types of self-examinations necessary to manage diabetes or HIV - tasks that are just as challenging at home as they are abroad. In some areas of Chicago the diabetes rate is as high as 25 percent, and African-American populations have much higher rates of diabetes complications such as blindness and amputation.

“It seemed to me that we had a lot of the same problems on the South Side of Chicago, so why not try it there?,” Dick said.

To test this premise, Nundy and Dick joined efforts with Medical Center faculty Monica Peek and Marshall Chin, who recently received grants from the Alliance to Reduce Disparities in Diabetes and the National Institutes of Health to look for new ways to improve outcomes in South Side neighborhoods. For a pilot study published last month in the Journal of Diabetes, Science, and Technology, the team recruited 18 African-American diabetes patients to try out a new automated text-messaging communication system that they programmed.

The study participants were not your typical teenage texters, instead reflecting an age range (38-72) more commonly afflicted with diabetes.

“If this is going to work, we needed to look at middle aged people and people in their 60s and 70s. I’m less interested in having this as a hip thing for teenagers with diabetes,” said Peek, assistant professor of medicine. “It needs to be able to work in people I see in clinic. A 55-year-old black woman with diabetes, if it works for her, I’m interested.”

Each participant was asked at the beginning of the study what kinds of text message they would like to receive, with candidates including reminders to take diabetes medications, check blood sugar, or conduct self-examinations to detect potential complications. Participants could also customize when they received the message, and how often they came in over the one-month pilot.

Some were purely notifications (i.e. “Please take your medications now.”) while others required a text response (”How many times did you check your feet this week?”). In one early sign that the messages were reaching their targets, participants often texted back whether a response was required or not, sending an “OK” or a “Thank you” message to what they knew was an automated system. The study reports, “Many participants found that they began anticipating the text messages and readying themselves to answer the questions in an affirmative way, such as preparing the insulin syringe ahead of the expected message.” That enthusiasm was reflected in surveys of the patients after the study period ended, where all but one participant said they were very satisfied with the text reminders.

“In the context of a population that typically has very few interactions with the health care system and may have experiences that are negative or bad or fearful, it was very fulfilling for them to have positive reinforcing messages where they really felt cared for by the system in a way they hadn’t in the past,” Peek said.

CSI: ALS

Posted at 1:31 pm CT on October 27, 2011

800px-protein_sod1_pdb_1azv

Finding the cause and the cure for a deadly disease is a little bit like investigating a murder. Clinicians collect clues from their patients, bring them back to the lab, and try to reconstruct the crime and identify the killer. For amyotrophic lateral sclerosis (aka ALS or Lou Gehrig’s Disease), this investigation has lasted over a hundred years - since neurologist Jean-Marie Charcot first described the disease in 1874. But it’s only in the last two decades that ALS researchers have started to find major breaks in the case, revealing genetic clues to the origin of this deadly neurodegenerative disease. At a special ALS gathering at the University of Chicago, Medical Center neurologist Raymond Roos told nearly 200 patients and caregivers that the case may finally be cracked soon.

“I think the field is on fire now,” said Roos, the Marjorie and Robert E. Straus Professor of Neurology. “I think it’s astounding and exciting what’s going on with respect to neurodegenerative diseases and absolutely ALS. We have all these things piling up now and we are continuing [to look]. Should we be optimistic about the future? Yes.”

Wednesday’s gathering, put together by the Greater Chicago Chapter of the ALS Assocation, was a unique two-part event featuring both a symposium for researchers of the disease and a luncheon/health expo for the patients and their families. In one room of historic Ida Noyes Hall, 14 Chicago scientists studying the origins of ALS and developing new treatments for what is currently an incurable disease shared their latest results. Meanwhile, patients and their families learned about medical devices and advocacy opportunities, and shared stories of how they cope with their disorder.

The day’s scientific component demonstrated both why the ALS investigation has taken so long, and why Roos thinks there is cause for optimism. The central mystery of ALS is why it selectively targets the motor neurons of the nervous system, the extremely long cells that deliver instructions from the brain to the muscles of the body. As the motor neurons die off, the patient experiences a progressive paralysis, losing the ability to maintain balance, walk, and eventually, breathe. Figuring out what causes this specific population of neurons to perish will point the way to treatments that slow or even reverse the progression of the disease.

For suspects, scientists have looked to genes. Roughly 10 percent of ALS cases are inherited through generations of families, indicating a genetic cause. While this population might be only a small minority of cases compared to the more common “sporadic” cases, they could be a foothold along the path to understanding both types of ALS.

“Those are very important even though they make up this small group, because they open a window,” Roos said. “If we can identify the gene that’s mutated, we can figure out what the function of that gene is. The hope and assumption and, I think, the reality, is that information will guide us into understanding the non-inherited, sporadic form.”

In 1993, scientists discovered the first ALS-associated gene/suspect, called SOD1. Though mutations of this gene explain only 20 percent of the familial 10 percent, they have been an important clue into exactly what goes wrong inside a motor neuron during the disease’s tragic march. The morning’s sessions zoomed in on these details, describing how a faulty SOD1 can kill off a cell through to the aggregation of cellular proteins, the interruption of the cell’s highway-like transport system (presented by UIC’s Gerardo Morfini and Scott Brady), and the creation of a “toxic channel” (as told by UCMC’s Michael Allen). The damage caused by SOD1 mutants might not even be limited to the motor neurons themselves, as Roos presented research demonstrating its toxic activity in the cells surrounding those neuronal types.

The path from what goes wrong to the creation of new potential therapies for ALS was explained by Richard Silverman, a chemist from Northwestern University. By screening for compounds that prevent the type of protein aggregations observed in the motor neurons of ALS patients, chemists hope to design new drugs that will slow the damage and hopefully, the physical symptoms they produce. Silverman detailed the incremental design of two new compounds in his laboratory that, in animal studies, produce an extension of life that is two to three times longer than seen with the only drug currently approved for use in ALS, riluzole.

Rebuilding the Doctor-Patient Relationship

Posted at 8:16 am CT on September 23, 2011

bucksbaum-panelMedical students spend the first half of their education learning anatomy and physiology, and the second half applying that knowledge in the hospital. But where in that process do they learn the very important skill of listening and talking to their patients? In the panel discussion that followed yesterday’s announcement of The Bucksbaum Institute for Clinical Excellence, it was clear that even physicians who graduated from medical school decades ago remember exactly when and from whom they learned those important lessons. In some cases, that mentor was sitting just a few feet away, such as when Mark Siegler spoke of his time as a medical student learning from the now 102-year-old Joseph Kirsner.

“The way you learn medicine is by seeing, not by talking. You have to show what good care is about. I learned from studying people like Joe,” Siegler said. “Joe told us that everything was important, [including] science and clinical inquiry, but patients came first, patients were the absolute first priority.”

The Bucksbaum Institute, made possible by a $42 million pledge from The Matthew and Carolyn Bucksbaum Family Foundation, has borrowed that sentiment as its defining principle. Teaching bedside manner may not be as straightforward as teaching biology, but creating a system of mentorship can help experienced physicians pass lessons down to young and aspiring doctors. Perhaps with serendipity, the panel represented that kind of mentorship family tree, with Dr. Siegler seated next to his former trainee Holly Humprey, dean for medical education, and Dr. Humphrey adjacent to current Pritzker 4th-year medical student Rebecca Levine.

[Watch video of yesterday's announcement and panel discussion.]

Each panelist and speaker at the event talked about the doctor-patient relationship as a phenomenon under threat in the modern health care system. Though better tests, treatments, and procedures have saved and extended countless lives, an increased reliance upon technology can interfere with the “old-fashioned” methods of taking a good patient history and answering patients’ questions.

“We were always taught that 90 percent of the diagnosis in medicine was based on what the patient tells you,” said Kenneth Polonsky, dean of the Division of the Biological Sciences and the Pritzker School of Medicine. “There are tendencies on the part of physicians to rely more on technologies than on what the patients tell them, their interactions with patients, and what they learn at the bedside.”

It makes sense then to start with doctors-in-training, and the foundation of the Bucksbaum Institute is the financial support of three to five new medical students a year as Bucksbaum Student Scholars [read more on the Insitute's organization in the FAQ]. Because of the Pritzker School of Medicine’s reputation as a “teacher of teachers,” (30 percent of Pritzker graduates go on to faculty positions at academic medical centers, Humphrey said), the hope is that the emphasis on doctor-patient communication seeded at the University of Chicago will spread around the country.

“This gift allows our medical school to make a very public statement to our students at the time they are applying to medical school and then during their experience in medical school, that the doctor-patient relationship is fundamentally important in the education of a physician,” Humphrey said. “Then, upon graduation, our students populate schools across the country and carry on that Bucksbaum tradition wherever they go.”

A Generous Gift to Improve Patient-Doctor Communication

Posted at 7:54 am CT on September 22, 2011

u-of-c-2In the physician’s office, the communication between doctor and patient can be just as important as any medical exam or test. To set a patient on a healthy path, a doctor must explain diseases and treatments in a manner that is accessible and relevant to each individual. The conversation must also be a two-way street, with the doctor listening to the patient instead of merely lecturing. In the increasingly technical and hurried world of medicine, more and more of that critical interaction is lost to 10-minute appointments and physician switching.

To counter that trend, an exciting new institute was announced at the Medical Center this morning. The Bucksbaum Institute for Clinical Excellence at the University of Chicago will be made possible by a $42 million pledge from The Matthew and Carolyn Bucksbaum Family Foundation. The institute, inspired by the relationship between the Bucksbaums and their long-time physician Mark Siegler, will focus on how to improve doctor-patient interaction and train the next generation of doctors how to be advisers, counselors, and navigators for their patients.

“These generous donors have pinpointed a fundamental aspect of medical practice that deserves greater attention,” said Kenneth S. Polonsky, MD, dean of the Division of the Biological Sciences and the Pritzker School of Medicine at the University of Chicago. “They are giving us the resources to concentrate on training physicians who not only possess extraordinary technical knowledge but can work effectively with patients to reach the best clinical decisions.”

An announcement ceremony this morning will be followed by a panel discussion of the patient-doctor relationship and patient outcomes, with Siegler, dean of medical education Holly Humphrey, and Pritzker medical student Rebecca Levine participating. That event will be webcast live, and coverage will follow here on the blog this afternoon. In the meantime, you can read more about the institute at the New York Times, hear a story about it at WBEZ, and watch the official announcement video below.

Finding the Muslim View on Medicine

Posted at 2:13 pm CT on August 15, 2011

sultanahmed_kneelMuslims are the fastest-growing religious minority in the United States, with over 7 million Americans declaring themselves as followers of Islam and more than 2,000 mosques nationwide. But in spite of the numbers, little data has been collected about American Muslims’ beliefs about health and disease, or their experience in the U.S. health care system. One reason for this also lies within the demographics, as American Muslims are a particularly diverse minority, containing South Asians, Arabs, and African-Americans, as well as both recent immigrants and long-term, multiple-generation natives. With such a wide variety of members from different ethnic, racial, and socioeconomic backgrounds, how does one pin down the health care experience of American Muslims?

The only way, thought Aasim Padela, was to talk to all of them - or at least representatives from each of the major groups in the American Muslim community. For his recent report, “Meeting the Healthcare Needs of American Muslims,” Padela and his colleagues at the Institute for Social Policy & Understanding went to the rich Muslim community of southeastern Michigan, one of the largest Muslim populations in the United States. Reaching out to multiple mosques and holding focus groups with over a hundred participants, the group looked for common denominators of people who share the Islamic faith, but perhaps little else.

“We looked at American Muslims as a conglomerate and asked what was common,” said Padela, assistant professor of medicine and director of the Initiative on Islam and Medicine at the University of Chicago. “We wanted to talk to each of these three large groups, which we know comprise the majority of American Muslims, and look at what’s similar in terms of health care challenges and beliefs. What we found as similar is something we can attribute to their faith.”

The final product was a fascinating piece of medical anthropology, a snapshot of how American Muslims view their own health or illness, the struggles they face in the U.S. health care system, and their solutions for establishing stronger communication between their faith and their medical caretakers. In an environment where physicians are expected to meet their patients halfway on ways to prevent and cure disease, understanding the perspective of a community that is already large, and growing larger, is an important first step toward improved care.

One primary finding of the report describes the “medical narrative” of American Muslims, their views on where disease comes from and the most effective strategy for fighting it off. Many participants in Padela’s focus groups believed that God takes an active role in health and illness, perceiving conditions from a winter flu to breast cancer as divinely ordained.

“Most participants perceived illness through a religious lens as predestined,” the authors wrote, “a trial from God by which one’s sins are removed, an opportunity for spiritual reward, a reminder to improve one’s health, and sometimes a sign of personal failure to follow Islam’s tenets.”

One might think that treating such a patient would be difficult for a physician, faced with a patient that believes they are being religiously challenged through their illness. But Padela said that a closer understanding of Islam refutes these fatalistic notions, and that most Muslims agree that health issues are best confronted with a combination of spiritual and medical healing.

“God also says to take care of your body, and that means you have to go to people in this world,” said Padela, who conducted the research as a Robert Wood Johnson Foundation Clinical Scholar at the University of Michigan. “Doctors are a part of that, but only a part. Imams play a big role in healing, in the sense that they help you understand disease and illness.”

Linkage 8/12: Physicians of Tomorrow & Molecular Furniture

Posted at 9:17 am CT on August 12, 2011

laurablinkhorn-forwebMedical school isn’t cheap. Today, medical students graduate with an average debt over $155,000, and the need to pay off those mortgage-sized loans drives many a young doctor away from more modestly compensated but sorely needed fields such as primary care and family medicine. To alleviate this financial pressure, many organizations have started scholarships to help with the med school tuition bill, rewarding scholastic achievements and commitments to work in underserved populations. The American Medical Association’s Physicians of Tomorrow program is one such effort, and this week’s announcement of the 2011 recipients [pdf] carried a heavy Pritzker School of Medicine presence.

maggiemoore-forwebTwo of the 18 (11 percent, but who’s counting) fourth-year medical students receiving the $10,000 scholarship were from the University of Chicago’s medical school. Laura Blinkhorn (left) and Maggie Moore (right) are the two very impressive Pritzker students among the recipients, each with very impressive biographies already built in their young careers. Blinkhorn has done work with South Side neighborhoods as part of the Pritzker Summer Service Partnership, works with the Washington Park Free Children’s Clinic, and is planning to spend 3 months of the next year doing a clinical rotation in the African country of Gabon. Moore volunteered at the Maria Shelter Clinic for Women and Children and the South Side “Girls on the Run” program, and somehow finds time to write poetry about her medical experiences. Because of poems such as “Cadaver Memorial” and a collection called “A Third Year’s Life in Lyrics,” Moore was given the Johnson F. Hammond, MD Scholarships supporting medical journalism by the AMA. Congrats!

New Furniture for Molecular Engineering

When you are building a new house, you’re gonna need some furniture. The same thing goes for building a new research institute - before you can fill it with people, you need somewhere for them to sit. The University of Chicago’s Institute for Molecular Engineering, which was born in December and acquired a leader in March, has this week announced four named professorships made possible by anonymous donations. The funded positions give the institute the power to recruit prominent researchers to help realize the institute’s unique vision blending biology, chemistry, and physics.

“The big job in front of us is to bring together people with expertise in broadly applicable areas of enabling technology, such as synthesis of new materials, biological engineering, new ways of doing computing and quantum information science,” said Matthew Tirrell, the founding Pritzker Director of the Institute for Molecular Engineering and senior scientist at Argonne.

Spiritual Benefits at the Bedside

Posted at 10:49 am CT on July 13, 2011

buddhist_prayer_beads201A patient in the hospital receives a long line of visitors, from physicians to nurses to medical students to other staff members. The conversations with most of these personnel tends to be mostly business - answering clinical questions or following instructions, with maybe a little bit of small talk squeezed in between temperature measurements and pill swallowing. Deeper conversations of a religious or spiritual nature may be left to hospital chaplains or religious representatives visiting the patient. But with only about two-thirds of hospitals providing pastoral care - and with tightening hospital budgets potentially threatening to push that number even lower - is it possible to measure the value of these spiritual discussions?

That was the aim of a new study by the research group of Farr Curlin, associate professor of medicine at the University of Chicago Medical Center. In an analysis led by medical student Joshua Williams, the team measured how many of over 3,000 patients in a survey reported having a spiritual or religious discussion while they were in the hospital, who that conversation was with, and most importantly, how it affected the patient’s opinion of their experience in the hospital. Published recently in the Journal of General Internal Medicine, the study found that a little bit of attention to a patient’s spiritual concerns boosted patients’ satisfaction with doctors, confidence and trust in their physicians, their feelings about the teamwork between doctors and nurses, and their rating of the overall care received.

“Our data is the strongest data so far that having these issues addressed, even having them brought up, is something that people experience as very positive,” Curlin said. “What’s interesting is it didn’t matter whether the patient said they wanted it, just having had it was associated with higher rates of satisfaction across four different measures.”

Surprisingly, the source of the spiritual or religious conversation was less important than the content. The benefits were the same whether patients talked with a chaplain, a physician, or even a religious figure from outside the hospital, Curlin said. Furthermore, while most of spiritual discussions were originated by chaplains (61 percent), the patient satisfaction figures suggested the good vibes were contagious, spreading out to improve patients’ feelings about the other members of their health care team.

“It was the whole experience: the physicians, the clinical team that took care of them,” Curlin said. “The care they received at the hospital was rated more highly if someone talked to them about spiritual concerns.”

The effect was not limited to patients with strong religious beliefs, or even those who sought out a patient ear for their spiritual thoughts. Forty-one percent of patients said they wanted to discuss such concerns, but even patients who weren’t seeking spiritual counsel but were approached anyway demonstrated the same positive influence upon their experience in the hospital. Curlin said that a benefit even for non-religious patients indicated that the effects of talking to a chaplain (or a physician, or a friendly custodian) were more about being recognized as a person instead of a patient.

The New Landscape of Hepatitis C

Posted at 8:21 am CT on July 5, 2011

hepcThe hepatitis C virus has always been an unusual disease. Largely symptom-free in its early stages, many people are unaware for many years that they have contracted the virus. But if left untreated, hepatitis C can eventually cause severe liver damage that may necessitate an organ transplant. Until recently, physicians have had only limited success in combating the hepatitis C virus, administering a lengthy combination of two drugs that completely cured less than half of the patients treated.

However, in recent months the forecast for curing hepatitis C patients became much sunnier. The near simultaneous FDA approval of not one, but two new therapies for the virus - called telaprevir and boceprevir - promises to dramatically improve the cure rate for the disease and prevent serious cases of liver cirrhosis and cancer. The two drugs are members of the same protease inhibitor class that has revolutionized HIV treatment, and adding one to the previous two hepatitis C therapies (forming what’s known as “triple therapy”) promises to increase cure rates to as high as 80 percent.

But new therapies bring loads of new questions and considerations for patients. At the University of Chicago Center for Liver Disease, which takes care of hundreds of hepatitis C patients, physicians Donald Jensen and Andrew Aronsohn organized a series of patient education sessions to address how the new therapies change the landscape of the disease. While many patients have been waiting years for the approval of telaprevir and boceprevir, choosing the right time to begin therapy is no simple decision. Because the therapy still takes between 24 and 48 weeks to complete, and must be closely monitored to make sure the protocol is successfully followed by the patient, hepatitis C clinics can only start treating so many patients at a time. In an editorial for the journal Hepatology, Jensen and Aronsohn explained why the University of Chicago has thus chosen to treat the sickest patients first, asking hepatitis C patients in the earlier, less severe stages of the infection to delay their therapy with the new agents.

To further spread information about these decisions, the basics of hepatitis C, and the impact of the new therapies, Jensen and Aronsohn agreed to film a series of videos for ScienceLife. Watch as the two physicians explain how the new therapies work, what patients can expect from the new treatment protocol, and why it is important for patients and their physician to choose the right time to start therapy.

Popular Mechanics typically offers step-by-step guides for changing your oil or building a bookcase. But in a recent feature they seriously upped the instructional ante with an “Extreme How-To” - How to Perform Open Heart Surgery. The expert chosen to guide their readers through this don’t-try-this-at-home process was Medical Center cardiac and thoracic surgeons Jai Raman and Shahab Akhter who helped develop a new technique in heart surgery called the “wrap procedure.” The surgeons do a great job of explaining how the surgery has changed over the years, particularly in the materials used for repairing the heart and sternum after surgery to speed recovery and decrease scarring. “You’ve got to get comfortable putting stitches into a beating heart,” is just some of the sage advice that Raman offers in the piece.

The end of the academic year always brings a bounty of teaching honors, voted on by medical students, residents, and faculty peers. For the 2010-2011 year, more than two dozen awards were handed out by the Pritzker School of Medicine, the Biological Sciences Division, and departments of the Medical Center. For an awards roundup from both sides of campus, visit this article at the University of Chicago News Site.

An Extraordinary Transplant Triple Play

Posted at 8:45 am CT on June 21, 2011

uch_026630-1

By Dianna Douglas

Darryl Williams got winded while running an annual 10K race in Oak Park in 1995. Puzzling, since he was in excellent shape. Over the next five years, he had irregular heartbeats and felt strange sensations in his chest. But none of the treatments his doctors tried made a difference.

Allen Anderson, associate professor of medicine and director of the Advanced Heart Failure Program, met Williams in 2000. The arrhythmia was becoming life-threatening. Anderson diagnosed Williams with sarcoidosis of the heart, an inflammatory disease, and began to treat him with medication.

Williams was determined to get better. He followed his doctor’s orders and took his medications, even when they had toxic side effects. “We were able to control it for 10 years,” Anderson said. “He did his part as well, by taking care of himself.”

But Williams’ sarcoidosis continued to grow. The disease, which affects about 18 people per 100,000 annually, spread to his liver. Soon his ailing heart and liver put serious strain on his kidneys. Anderson decided that his only hope was a new heart, liver and kidney. “He was in heart failure and liver failure. He was critically ill. He was going to die.”

The criteria to be considered for a three-organ transplant are stringent. “We have to be very careful about patient selection,” Anderson said. A heart, liver and kidney transplant is a massive surgery. “We have to pick patients who have a good chance of survival.”

Williams’ case was the subject of many multidisciplinary meetings, with hematologists, surgeons, nutritionists, psychiatrists, social workers, infectious disease specialists. “The fundamental question is: are you going to commit organs to this person?” said John Renz, professor of surgery and director of the Liver Transplant Program. “You have to look at all aspects of a patient. And you have to feel that you are committing that precious resource well.”

After multiple screenings, the team was convinced. At 55 years old, Darryl Williams didn’t have any other health problems that would complicate his recovery. He was always careful to follow his doctors’ instructions, and would likely keep taking his medications after a transplant surgery. And, as important as anything, he had a large family and community of friends to support him through the ordeal.

After three months of waiting in the hospital for the transplants, Williams was rolled into an operating room.

“It’s an extraordinary surgery,” said Valluvan Jeevanandam, professor and chief of cardiac and thoracic surgery. “People don’t do well after any open heart surgery without a good functioning liver,” he said. “The liver has to filter out toxins and promote coagulation. Similarly, a new liver won’t do well without a good heart.”

He compares multi-organ heart transplants to “walking a tight rope without a net under you.”

There are other pressures, too. After leaving the deceased donor, the heart is only good for about five hours. A liver can be transplanted for 18 hours, and a kidney can sometimes be good for up to 48 hours. So, the heart goes in first.

“From a technical point of view, all three surgeries have to be perfect,” Jeevanandam said. “The challenging thing is sewing in all three organs in an environment hostile to any transplant procedure.”

The heart transplant was over in about four hours, but the heart was struggling. “We had to maintain his heart until he could get his liver,” Jeevanandam said. The surgeons used inotropes to stimulate the heart and a balloon pump to keep oxygen flowing.

Then Renz and the liver transplant team took over. read more

3Teaching with Treadmills

Inside the Biological Sciences Learning Center on the Medical Center campus is a laboratory that looks more like a gymnasium. Six state-of-the-art treadmills and six futuristic exercise bikes sit around the room, each connected to a computer alongside modified oxygen masks and suction cup sensors. Instead of dissecting frogs or mixing chemicals, students show up to lab sections in shorts and running shoes, prepared to sweat for science. In Mark Osadjan’s “Metabolism and Exercise” course, part of a two-quarter Exercise and Nutrition sequence, there’s no sitting on the sidelines.

Since joining the University of Chicago as a senior lecturer in 2003, Osadjan has designed courses that teach undergraduates about biology by connecting with what most college students care about: keeping fit, and sex. As part of the UChicago core curriculum, every undergraduate must fulfill a biology requirement, even if their interests lie in political science, music theory, or philosophy. With his “Metabolism and Exercise” and “The Biology of Gender” courses, Osadjan has met these science-shy students halfway, filtering instruction on evolution, physiology, and genetics through their own personal hobbies and interests. The efforts have been such a success that Osadjan’s courses fill up soon after registration is opened.

Today, Osadjan was announced as one of this year’s recipients of the Quantrell Award for Excellence in Undergraduate Teaching, an esteemed UChicago honor that goes back to 1938. Last week I met with Mark to talk about his award and his career path, from a graduate student studying Antarctic fish to an instructor of graduate-level science to his current position, teaching predominantly undergraduate non-biology majors.

“It’s always a trick to figure out how to teach with enough enthusiasm, such that it spills over to the students,” Osadjan said. “It’s our challenge not only to teach these students a certain number of facts, but to show them why those facts are important, relevant, and worth thinking about throughout life.”

Most college students spend their summers traveling the country or working an internship, but 20-year-old Rachel Garneau had other plans: donating a kidney. On Tuesday morning, Garneau came to the Medical Center and made the rare gift of an altruistic kidney donation, triggering a kidney swap chain that helped patients in need of the organ in New York and Madison. Neil Steinberg at the Chicago Sun-Times followed the story before and during the surgery, and got some great play-by-play commentary from Yolanda Becker, professor of surgery and director of the kidney and pancreas program.  For instance: “‘The pancreas is the bitch of the abdomen,” she confided.’”

Are clinical trials handicapped by their own success? A new analysis from Anup Malani and Tomas Philipson of the University of Chicago Law School finds that trial enrollment for a given disease plummets when a treatment is found to be effective, using AIDS clinical trials after the approval of anti-retroviral therapy to illustrate the point. Richard Schilsky, professor and section chief of hematology/oncology at the Medical Center, agreed with the findings at Nature News: “There are so many options that patients are not flocking to get into clinical trials like they used to.”

Small Screen, Big Quality Improvement

Posted at 9:37 am CT on April 19, 2011

bmi-chartThe benefits of measuring body mass index (BMI) are clear: a physician who knows a patient’s BMI is more likely to counsel her on lifestyle changes, and people are more likely to try diet and exercise on a doctor’s advice. But in the often-rushed environment of the clinic, even the quick calculations required to know a patient’s BMI can get lost in the shuffle.

Internal medicine residents at the Medical Center noticed that almost none of their patients had a BMI recorded on their charts, but many of their patients seemed overweight and obese.

“They initially wanted to improve obesity rates in patients,” said Vineet Arora, MD, who participates in teaching a quality improvement curriculum to residents and is senior author of a study. “But we needed something feasible. Recording and calculating most patients’ BMI was something they could change.”

Their quality improvement initiative and a study about it, published online in March in the American Journal of Medical Quality, grew out of the quality improvement education that all residents now receive at the University of Chicago.

Neda Laiteerapong, MD, was an internal medicine resident at the University of Chicago Medical Center when she decided that measuring BMI was vital to improving patient care. “We couldn’t even identify who was obese in our clinic. If you don’t identify it, you’re not going to treat it on a patient-by-patient basis,” she said.

Laiteerapong and nine of her fellow residents looked at the triage of patients in the clinic, and decided that they could easily make a few small changes to the vital signs that nurses record when a patient is checked in. “Most clinics weigh people, but they don’t measure height,” Laiteerapong said, noting that the combination of height and weight is usually only measured in children. She also said that asking a patient his height isn’t an accurate way to calculate BMI, since people often overestimate how tall they are.

The residents added rulers in the clinics, height and weight charts in the patient rooms, and a slot on the patient intake form for BMI. The nurses took the measurements, and the residents were responsible for calculating BMI. Within a month, the number of patients with a recorded BMI jumped from 4% to 80%.

Julie Oyler, MD, assistant professor of medicine and associate program director for the internal medicine residency, implemented the quality improvement curriculum for residents in 2006. “I would consider this a successful project,” she said. “Instead of complaining about poor practices in a clinic, the residents are getting experience changing and fixing the clinics.”

Crowdsourcing the War on Cancer

Posted at 8:58 am CT on March 28, 2011

yellow-strongReading The Emperor of All Maladies, Siddhartha Mukherjee’s “biography of cancer” from last year, one is struck by both the long and short history of cancer. Descriptions of breast cancer can be found as long ago as an Egyptian papyrus dated to 2500 BC and ancient Greek histories, and tumors have been found in thousand-year-old mummified remains from Peru. But the idea of cancer as a treatable disease is barely a hundred years old, and as recently as the 1940’s, clinicians could do little more than help patients die from the disease as comfortably as possible. Despite these deep historical roots, Mukherjee chooses to start his book in 1947, with Sidney Farber’s first experiments on chemotherapy for children with leukemia.

From there, the pace of the “war on cancer” (though not known by that phrase until 1971’s National Cancer Act) accelerates rapidly, as chemotherapy, radiation and surgical protocols were improved through scientific inquiry. Progress in understanding and treating cancer no doubt seemed incremental as it was happening, and even today some still question its overall success. But Mukherjee’s skillful portrayal presents an astonishing difference in the experience of cancer patients only 50 years apart - from being hidden in out-of-the way wards because of the hopelessness of their condition, to the ultra-modern cancer centers of today offering targeted treatments that offer the promise of a cure, if not yet a certainty.

But stumbling blocks still exist in the scientific progress against cancer. One place where reinforcements are desperately needed is at the level of clinical cancer trials, where the true benefits of laboratory discoveries are put to the test in a human population. While there is no shortage of ideas for new cancer therapies, clinical trials have struggled due to insufficient accrual of patients. Though 25,000 to 30,000 patients are enrolled in cancer trials each year, they only represent 3 to 5 percent of all U.S. adult cancer patients,  Richard Schilsky, professor of medicine and chief of hematology/oncology, wrote in a commentary for Science Translational Medicine last week.

“Despite various attempts to remedy the accrual problem, such as awareness campaigns, establishment of clinical trial registries, and the development of search engines to match patients to trials, annual enrollment on cooperative group clinical trials has remained essentially unchanged throughout the past decade,” he writes. As a result, “up to 40% of cooperative group phase III trials have failed to complete accrual and closed without achieving study endpoints, wasting the contribution of those patients willing to enroll in the trial.”

There are plenty of barriers against getting cancer patients into appropriate trials, Schilsky says. Many are institutional - physicians outside of the academic world may not have dedicated research staffs than can help coordinate patients, deal with regulations and insurance issues, and fill out the extensive paperwork. To circumvent these issues, some doctors would rather write off-label prescriptions for drugs being tested in a clinical trial, getting the potential benefits of the drug without the logistical commitments. On the other side, patients may not be aware of the trials available to them, or may misunderstand the purpose of a clinical trial.

The new era of molecular medicine could raise some of these obstacles even higher or knock them down, Schilsky writes. In 2001, the drug Gleevec ushered in the age of smarter drugs that directly interfere with the cause of the disease, rather than general features of tumor growth. Testing these types of drugs requires new types of trials, with more biospecimens (blood, tumor tissue, DNA) collected from patients and tighter rules about who is eligible for the experiments. Classifying broad cancers into more specific subtypes may eventually improve treatment effectiveness, but in the short term could make testing those treatments even more difficult.

“The challenge is that many patients may need to be screened if the biomarker used for patient selection is of low prevalence in the tumor type under study,” Schilsky writes.
