Teaching Doctors How to Close Life’s Last Door

February 9th, 2012

At age 78, Charles Swanigan could jog three miles at a stretch. One year later, with the prostate cancer he had battled for a decade spread throughout his body, he could hardly move. Just getting out of bed, he tells his doctor and two BU School of Medicine students paying him an autumn house call, wracks him with pain. View the video here.

Swanigan’s cozy Roxbury living room, with its fireplace and hardwood floor, has added a new piece of furniture: the hospital bed where Swanigan spends his days, shriveled arms protruding above the blankets. Eating has become an ordeal; the food will no longer stay down. The retired property manager, a divorced father of four, is cared for by his 20-year-old son. As Eric Hardt, a MED associate professor and a Boston Medical Center geriatrician, tells his students, the patient has endured a radical prostatectomy and “every drug known to man.” Yet Swanigan constantly clutches at new treatments that might prolong his life. “He’s going down fighting,” Hardt says.

Now, Hardt watches in the darkened living room as Lucas Thornblade (MED’12) checks Swanigan’s vitals, including his pulse. Thornblade’s examination roams far beyond questions of blood pressure and weight. “I was going to ask how you’re doing spiritually and emotionally,” he says. “I’m not sitting here worrying,” Swanigan answers. “It’s just, it’s not fun sitting here in bed.”

Hardt asks if any fellow parishioners from Swanigan’s church ever stop by. “A few,” says Swanigan. “I would have thought I’d have more, but…”

“This is kind of hard to talk about,” Hardt says, “but what if something unexpected and terrible happens?” Swanigan says he has a will. “If your heart were to stop beating,” Thornblade says, “some patients would prefer to have CPR and electric shocks given.”

“If that happened,” Swanigan asks, “how much of an extension is it? Just a few weeks, a month or so? I prefer not to be resuscitated and be in a lot of pain, if that’s what’s going to happen.”

“Thank you for sharing that with us,” says Thornblade, who helps Swanigan sign a do-not-resuscitate directive after the patient is assured that it won’t preclude necessary treatment.

“I heard you used to play clarinet. That was my father’s instrument as well,” says Thornblade. “Had a strong, strong desire to be a classical musician,” replies Swanigan, who studied at the Boston Conservatory of Music. “But it’s a tough field unless you want to go into teaching.”

“Any plans for Thanksgiving or the holidays?” the doctor asks.

“No,” says the patient, “nothing.”

Death is a toxic subject for doctors trained to heal, not prep their patients for the morgue. “No one wants a talk about it, because it doesn’t make for a good story,” says Matthew Russell, a MED assistant professor. Russsell (CAS’94, SPH’03) says end-of-life needs weren’t part of the curriculum during his medical training in the 1990s. A 2007 study of 51 oncologists by Duke University’s Center for Palliative Care (palliative medicine tries to relieve pain and suffering) found that even when cancer patients did open up about their sorrows, fears, or anger, the discomfitted docs doused the discussion three-quarters of the time.

That’s changing. MED’s old-fashioned house calls—after 150 years, the oldest such program in the country, Hardt says—are an important part of the palliative and end-of-life training in the school’s four-week geriatrics clerkship. (Clerkships are medical students’ temporary assignments in various hospital specialties.) Lectures instruct students how to be human beings as much as doctors, and that emotional connections with dying patients are as essential to good care as a stethoscope. The students also learn that while death is universal, how we die is tailored by our individual cultural and spiritual heritage.

Hardt, one of 15 docs on BMC’s geriatrics team, says the training grew partly from the observation that there are more people dying within the geriatric group than anywhere else in the hospital, including the intensive care units and oncology. The lesson has taken hold in medical schools nationally, where end-of-life care, including palliative medicine, is a growing trend, says David Longnecker, director of health care affairs for the Association of American Medical Colleges. Longnecker says that BU’s education in these fields is highly regarded.

The move has been fueled partly by reports such as a 2009 article in the Association of American Medical Colleges journal Academic Medicine, in which residents who’d been given bedside training with dying patients reported feeling more competent at end-of-life care.

Ebony Lawson (MED’12), who accompanied Hardt and Thornblade on the house call to Swanigan, says the visit showed her “firsthand how to approach difficult decisions.” She knows that a doctor inevitably deals with death, and she takes that discussion seriously. Still, she says, it’s emotionally difficult to talk about.

“How many of you have directly cared for a patient who died?”

Russell puts the question to the 10 students in the palliative care lecture he gives for the clerkship. A lone hand shoots up. “There is not a standardized dying patient,” he tells them. “People will have various symptoms to various degrees of intensity. We have to understand why this symptom is happening. The answer can’t be morphine, morphine, morphine in every case.” He warns that rote, inept treatment could accelerate the decline of a patient whose “goal could be making it the next few weeks to their granddaughter’s christening.”

The case studies that Russell cites are thick with medical jargon, but of his three Ms of medical examination, only the first, mechanism, probes a patient’s pathology and treatment. The second, meaning, explores what illness means to the patient herself—for example, asking what worries her about being nauseous. “It sounds weird, people don’t do it, and you don’t hear it all that much,” but mere yes-no questions about symptoms fumble the chance to be of real help, he says. He exhorts the students to remember who their patients are as people. “It’s the spouse of 60 years who’s going to lose a wife, the family who’s going to lose a matriarch. Our bread and butter is a patient and family’s worst day.”

The third M is a stunning word for a medical class—magic—all the more so for the humility it teaches a profession not known for being humble. The dying crave a miracle that will save them, Russell says, but healers must not oversell their powers in hopeless cases. “Remember the lesson of the Wizard of Oz,” he urges.

“There’s no place like home?” ventures a student.

“Oh, sh–,” says Russell with a laugh—he’d forgotten that famous moral of the story. “That’s not it. Another lesson.” He’s referring to the movie’s insight that the man behind the curtain is just a man. “We have to be mindful of our participation in that illusion of Oz,” he says. “Patients will often want us to be the wizard. You owe it to your patients to be true to what you know—which is limited.”

Underscoring the limits of care is the need to understand how a patient perceives them. Russell offers a case study of a 95-year-old demented woman who, near death, has stopped eating. Research confirms that her feeding tube will not prolong her life. Yet how do you suggest to her daughter that she order it removed? Students take a stab at the medical facts of the situation (“Unfortunately, she’s not going to be able to eat on her own,” tries one), but Russell reminds them that their doctor’s ear must hear the voice of the daughter’s heart.

“What is feeding someone? A proxy for something.” Love, suggests a student. Bingo, says Russell. “‘So don’t you ever tell me not to feed my mother, because she fed me every night.’ Food is love. You’re going to have to deal with that love thing. Make them know that what they’re not doing is love. I need to know that what I have done for my loved one matters and has mattered, because I want to know, at the close of their life, I have done everything I could have done. What needs to happen at that moment? An emotion. She needed to hear, ‘You did right.’”

In 2005, with help from an Aetna grant, Hardt developed a curriculum, called Culture, Spirituality, and End of Life Care, that attunes aspiring doctors to help patients of varying races, religions, and nations.

“We don’t have time to talk about all of America’s wondrous versions of racism,” he tells his class, making it clear that a doctor must never “lower the standard of care just because you don’t know the patient’s language.” Among his case studies is a Boston Globe story about a Buddhist family’s battle to keep their father on life support. Although his brain activity had flatlined, and “brain death equals death” in Western medicine, says Hardt, his heart continued beating, and to his family, that meant “the spirit still dwells in the body, so you can’t pull the plug.” Students struggle unsuccessfully with possible resolutions; in reality, Hardt says, the doctors kept life support on.

Nowhere does MED’s emphasis on diversity and humanity spice the curriculum more than in the final project of the clerkship. Outsiders expecting exam books or meticulously wrought case studies would be astounded at the actual projects that fourth year med students presented in November, from the aroma of jambalaya made by Toya George (MED’12) to a version of Jeopardy! with questions about international religions, emceed by Casper Reske-Nielsen (MED’12).

Jambalaya, plus the spirituals she plays on her computer for the class, reflect the comforts taken by people who share her southern heritage, George tells her classmates. Reske-Nielsen’s Jeopardy categories, flashed on the classroom screen, ranged from What’s in Store? (about the afterlife notions of various faith traditions) to Death’s a Drag. Classmates competed to answer clues like, “Famadihana is the practice of this with the dead to help the spirits join their ancestors.” (Answer: What is dancing? Famadihana is a tradition in Madagascar.)

The final projects’ nonscientific flavor, Hardt says, is a deliberate antidote to the emotionless professionalism that doctors typically adopt when confronting death and the bereaved: “‘Get tough, I’m sorry for your loss, suck it up.’ And we want to combat that and say, you know, these are people. And even though you have a specialized job, you’re still people too. You don’t have to block that out to become a good surgeon or good internist.”

It’s a lesson that stayed with Lucas Thornblade long after his visit to Swanigan’s home. “Learning about palliative care is the process of choosing which elements of medical care are appropriate for a person with a disease that may be terminal,” he says. And with the geriatrics clerkship, “for the first time, we’re caring for patients who may have more emotional and physical needs outside of the hospital than the patients that we’re used to caring for.”

Charles Swanigan died at home the evening after Thanksgiving with his family at his bedside.

GSDM Students Discover One-of-a-Kind Learning Experience in Guatemala

January 31st, 2012

 

Three fourth-year dental students: Melissa Lowry, Dee Gulis and Lucinda Barry recently returned from a trip to Poptun, Guatemala with LIGA International. The trip took place Jan.12-23. While in Guatemala the students, along with alum Kevin Acone DMD ‘07, and trip organizer Dr. Fred Kalinoff, spent five days treating patients of various ages in the Dental Clinic at the Poptun Hospital.GSDM guatemala2

Ordinarily there is one local dentist who sees patients at the Poptun Hospital in the mornings, but his schedule is a bit unpredictable. So when the GSDM volunteers arrived at the Poptun Hospital the local residents turned out in force for a chance to be treated.

“We worked five days at the hospital, working from eight to 10 hours per day. We rotated patients between the three of us and performed a combination of extractions and restorations. We had to work with limited instruments and supplies and it was difficult treating at times because people had such a great need and there was not enough time to fix everything,” said Lowry.

The students estimated that they treated between 150 and 200 patients. They performed most of the treatment, but Drs. Acone and Kalinoff were always on hand to oversee and assist if necessary. Many of the patients presented with cases the students had never seen before.

Dr. Kalinoff explained one such case, “Every year we see a couple of very unusual cases, and this year was no exception. We were asked by the emergency room staff to see a patient with an abscessed tooth. We agreed and a few minutes later a wheelchair arrived with a lady of about 40 who looked more dead than alive.” Dr. Kalinoff continued, “She had a draining abscess from the angle of her right mandible that had created a hole about three centimeters by two centimeters with copious amounts of drainage. The right side of her face was swollen from above the ear down into her neck and the swelling was rock hard. She had a fever of about 102, with considerable lassitude, and was verbally unresponsive. Our main concern was that the swelling in her neck would soon cause her to suffocate.”

For this patient Dr. Acone cleaned the wound and then worked with the Emergency Room staff to arrange for IV antibiotic treatment, which the patient was kept on for the entire five days that the group worked at the hospital. Dr. Kalinoff said, “By the time we left 90% of the swelling was gone and there was talk of sending her down to Guatemala City to eventually close the wound.”

Needless to say, this trip was a learning experience for the students. Lowry said, “It was great having the freedom to operate as a dentist but the accessibility of help if it was needed. We saw so many different cases that we haven’t seen before.”

Added Gulis, “Dr. Acone was amazing to work with and a great person to lead a trip like this.”

Also on the trip were Dr. Kalinoff’s wife, Tricia, and Barry’s husband, Dan, who the group affectionately nicknamed “Dycal Dan”. Dycal Dan acted as dental assistant, photographer, and took care of the instruments. Barry said the trip exceeded both of their expectations and the others agreed. They all hope to get involved with this trip again and to be able to play a role in expanding the outreach efforts so that the residents of Poptun see a marked improvement in their overall oral health.

“I cannot say enough about these students. Dee, Melissa, and Lucida were all tremendously hard and willing workers. They showed very good knowledge of their chosen field and will be leaders in the dental industry in the future,” said Dr. Kalinoff.

NEIDL Goes Public: BU Biosafety Labs Offer Tours to Press, Politicians

January 27th, 2012

John R. Murphy and Ronald Corley may be the most highly educated tour guides in Boston.

Murphy, a School of Medicine professor of medicine and microbiology, researches the ways that bacterial protein toxins get into cells. Corley, a MED professor and chair of microbiology, investigates immune responses to viruses. But much of their time recently has been spent leading visitors through the many chambers of the National Emerging Infectious Diseases Laboratories (NEIDL), where Murphy is the interim director and Corley an associate director. In recent weeks, the researchers have given tours for hundreds of police, firefighters, and EMTs as well as politicians and press, including the Boston Globe, which produced a video of the facility.

The tours have become increasingly popular since NEIDL, where researchers hope to develop diagnostic tests, vaccines, and new drugs for some of the world’s most infectious or deadly diseases, was given clearance by the Massachusetts Executive Office of Energy and Environmental Affairs in December to conduct research at Biosafety Level 2, with work beginning as early as February.

The lab was not granted permission to conduct more sensitive Biosafety Level 3 or Biosafety Level 4 research. Corley estimates that BSL-3 clearance could come within six months after the state reviews an environmental safety report being prepared by the National Institutes of Health. The opening for BSL-4 research is harder to predict. Regulators and the courts must rule on that first, pushing the date to at least October 2013, state officials say.

The state’s approval marks modest and hard-won progress for the nearly $200 million labs, which have sat unused on the Medical Campus pending legal challenges and regulatory review since being completed in September 2008.

The most recent tour by Murphy and Corley was arranged for BU Today and the Daily Free Press, with the intention, says Murphy, of getting the facts about NEIDL’s safety and security measures out to the community.

NEIDL interim director John R. Murphy in front of high tech air filtration systems atop the Biosafety Level 4 facility.

For starters, the 193,000-square-foot facility is surrounded by an eight-foot security fence. The grounds and building are under nonstop watch. All who enter must pass an iris scan, a metal detector, an X-ray machine, and an explosion detection device. And that’s just in the guardhouse.

Inside the main building guards again check visitors’ identification, issue them badges, and hand them over to their hosts. In fact, from here on, every entry point to any floor or lab requires an iris scan and a security card.

Murphy leads visitors first to the Biosafety Level 2 laboratories, where researchers will work on generally non-life-threatening diseases like meningitis, tuberculosis, Dengue fever, and measles. He approaches a wall-mounted iris-scanning device. Unlike in a Dan Brown novel, where a character uses an extracted eyeball to outsmart security, says Murphy, “the eyeball has to be live,” and—obviously—attached to a human being. He then swipes his card to open the lab suite’s door and a ticker clicks as each person passes. This is to ensure, Corley says, that no one “piggybacks” through the door. If the count does not match the number of iris scans performed, security is alerted immediately.

The BSL-2 labs look like standard chemistry course fare. Benches fill half of the room. A neighboring, self-enclosed tissue culture room is equipped with a biosafety cabinet and hood, where researchers sit to perform all sensitive experiments. Test tubes are opened only under these hoods, where high-efficiency small particulate filters capture any escaping pathogens. Researchers, who must wear lab coats, gloves, and protective eye and face gear, are trained to never bring an unsealed container outside of the hood. Cameras are strategically placed to record some, but not all, procedures.

On another floor, there are five Biosafety Level 3 suites, where researchers will work on viruses like West Nile, SARS (severe acute respiratory syndrome), and HIV, pathogens that are being investigated in 11 other labs in and around Boston.

Before stepping inside, Corley points to a magnehelic gauge above the door. The device measures airflow and ensures air (and any pathogens it may carry) is always directed inward and not toward the hallway.

In the lab’s antechamber, a Tyvek beekeeper-like bonnet and a high-tech face mask hang on a wall. Researchers don this equipment, gloves, and booties before passing through another vacuum-sealed door, which opens only when the first door has been locked. The setup is similar to BSL-2 tissue culture rooms, except that every ceiling light and vent, equipped with more high-efficiency filters, is hermetically sealed, and every action is recorded by video cameras.

On the facilities floor, gleaming air filtration systems stand in seemingly endless rows. Murphy addresses visitors from a perch atop what he describes as a completely different building—Biosafety Level 4 area. “It literally is a building within a building,” he says, adding that BSL-4’s ceiling, walls, and foundation are made of “the most heavily rebarred concrete you can imagine.” The Level 4 lab also sits on independent horizontal beams that in case of an earthquake allow the building to vibrate independently of its neighbor.

NEIDL has backup generators and steam sources that would keep the facility fully functional for three days if there is a power outage, long enough to destroy or decontaminate any existing pathogens.

Finally, the group arrives at the floor housing seven Biosafety Level 4 labs, where researchers will study pathogens like the Ebola, Marburg, and Hendra viruses. Early on, Corley emphasizes that while these viruses are deadly, they are not all highly contagious. Most are transmitted through blood or mucus, not through the air.

BSL-4, Murphy says, is like “a submarine in a bank vault,” with 12-inch-thick walls to prevent leakage and to withstand regular formaldehyde and peroxide cleansing baths.

Researchers wear these baby blue space suits, filled with a constant stream of filtered air, while working in BSL-4 labs.

Here, visitors pass through an anteroom similar to the BSL-3 labs, then enter a room where baby blue space suits (at $2,600 apiece) hang from a wall. Researchers step inside and connect to a tube that feeds filtered air inside the suit, which “blows up like the Michelin blimp,” Corley says. They wear three pairs of gloves, one sealed with duct tape to the suit’s cuffs, and green garden boots.

Once dressed, researchers step through a double-doored shower chamber before arriving in the lab. More cameras are mounted on the ceiling alongside computer screens used for internal communication. Fire sprinklers, heat sensors, and an emergency lighting system aid workers in the case of a fire. NEIDL staff is currently working on a wireless communication system for BSL-4 researchers.

Before leaving the lab, suited personnel must pass through a seven-minute chemical shower, after which they remove their suits, place scrubs in a bag, and shower (again) thoroughly. Suiting up and dressing down takes a full hour, Corley says, so bathroom and lunch breaks are scheduled carefully around lab time. And no one reaches BSL-4 without having successfully practiced this drill at least five times at NEIDL’s in-house training facility.

All scrubs, trash, and liquid waste is disinfected or decontaminated by researchers before being dumped. “Housekeeping doesn’t come in,” Corley jokes, and nothing goes out unless it is clean.

“All biosafety is really about keeping the worker safe,” he says. And a safe worker means a safe community.

Corley and Murphy acknowledge that accidents have happened at Boston biosafety labs, including a 2007 evacuation of a BU BSL-3 lab where scientists were working on the virus that causes rabbit fever. But they are convinced that a well-trained staff and an engrained culture of safety can prevent such accidents.

The Medical Campus, they say, is an excellent location for NEIDL, despite its surrounding population. It offers a hub for power and steam sources for sterilizing scrubs and equipment and has well-trained first responders. And a medical campus is a great place to train the next generation of researchers.

“You’re not going to recruit the best minds out in the middle of nowhere,” Murphy says.

And Corley, for one, is confident that when it comes to recruiting expertise, NEIDL will be a very big draw: “We expect to outcompete every facility,” he says. “We expect to get the very best people.”

PCE in Drinking Water Linked to Increased Risk of Mental Illness

January 25th, 2012

Early childhood exposure to water contaminated with the solvent tetrachloroethylene (PCE) increases the risks of bipolar disorder and post-traumatic stress disorder, a new study by BU School of Public Health researchers has found.

The study, published in the journal Environmental Health, found that while there was no association between PCE exposure and the incidence of depression, people with prenatal and early-childhood exposure had almost twice the risk of bipolar disorder compared to an unexposed group. The risk of PTSD (post-traumatic stress disorder) was raised by 50 percent. Those with the highest exposures reported the highest rates of the two mental illnesses.

PCE, a solvent used in dry-cleaning and other industries, is a neurotoxin known to cause mood changes, anxiety, and depressive disorders in people who work with it. To date, the long-term effects on children exposed to PCE have been less clear.

From 1968 until the early 1980s, water companies in Massachusetts installed vinyl-lined water pipes that were subsequently found to be leaching PCE into the drinking water supply. Researchers from BUSPH have been studying the effects of that exposure on both children and adults who were living on Cape Cod. The new study focused on prenatal and early-childhood exposure in eight towns: Barnstable, Bourne, Falmouth, Mashpee, Sandwich, Brewster, Chatham, and Provincetown.

Ann Aschengrau

Ann Aschengrau, professor of epidemiology at BUSPH and the study’s lead author, said that while it is impossible to calculate the exact amount of PCE people were exposed to, “levels of PCE were recorded as high as 1,550 times the currently recommended safe limit.

“While the water companies flushed the pipes to address this problem,” she added, “people are still being exposed to PCE in the dry cleaning and textile industries, and from consumer products, and so the potential for an increased risk of illness remains real.”

While the study examined the association between PCE exposure and schizophrenia, the authors said the number of schizophrenia cases was too small to draw reliable conclusions. In addition, they noted that the study relied on self-reports of mental illness, with subjects asked if a health care provider had ever diagnosed them with a mental disorder.

The new study comes on the heels of another BUSPH study that found children exposed to PCE-contaminated drinking water before birth and in early childhood were more likely to use illegal drugs later in life. That study, also published in Environmental Health, found that people with high exposure levels during gestation and early childhood had a 1.5- to 1.6-fold increase in the risk of using two or more illegal drugs as teenagers or adults. Specific drugs for which increases were observed included cocaine, hallucinogens, club drugs, and Ritalin without a prescription.

Besides Aschengrau, the team of BUSPH researchers on the new study includes: Janice M. Weinberg, Patricia A. Janulewicz, Megan E. Romano, Lisa G. Gallagher, Michael R. Winter, Brett R. Martin, Veronica M. Vieira, Thomas F. Webster, Roberta F. White and David M. Ozonoff.

The research was funded by the National Institute of Environmental Health Sciences Superfund Research Program.

The ADA Foundation—dentistry’s premier philanthropic and charitable organization—provides scholarships annually of up to $2,500 for pre-doctoral students entering into their second year of study. To be eligible, students must meet criteria for high GPA and rank in class, as well as demonstrate interest in professional activities and promise as future leaders in organized dentistry.

“This year only 50 scholarships were made available nationally, and the Dental School is both proud and honored that these three outstanding individuals are members of the GSDM community,” said Dr. Leone.

“Congratulations to Cassandra, Thomas, and Kenia,” added Dean Jeffrey W. Hutter. “They are all exemplary students and are truly deserving of this recognition by the American Dental Association Foundation.”

 

BU Study Finds New Genetic Loci Associated with Menopause Onset

January 24th, 2012

An international team of researchers from the Boston University Schools of Public Health and Medicine and other institutions has uncovered 13 genetic loci, linked to immune function and DNA repair, that are factors in the age of onset of menopause.

Menopause — the cessation of reproductive function of the ovaries — is a major hormonal change that affects most women when they are in their early 50s. Most prior studies of the age of onset of menopause have focused on genes from the estrogen-production pathway or vascular components.

In the new study, published online Jan. 22 in Nature Genetics, a research team led by Kathryn Lunetta, professor of biostatistics at the BU School of Public Health, and Joanne Murabito, associate professor of medicine at the BU School of Medicine, identified 13 novel loci associated with menopause onset, while confirming four previously established loci. Most of the 17 loci are associated with genes related to DNA damage repair or auto-immune disease; others are linked to hormonal regulation.

“Our findings demonstrate the role of genes which regulate DNA repair and immune function, as well as genes affecting neuroendocrine pathways of ovarian function in regulating age at menopause, indicating the process of aging is involved in both somatic and germ line aging” the authors said.

Lunetta said the new findings “bring us closer to understanding the genetic basis for the timing of menopause. They may also provide clues to the genetic basis of early onset or premature menopause and reduced fertility.

“We hope that as a better understanding of the biologic effects of these menopause-related variants are uncovered, we will gain new insights into the connections between menopause and cardiovascular disease, breast cancer, osteoporosis, and other traits related to aging, and that this will provide avenues for prevention and treatment of these conditions,” she said.

According to Murabito, director of the research clinic at the Framingham Heart Study, “It will be important to determine if a genetic variant that directly influences age at menopause also increases risk for later life health conditions, such as breast cancer.”

The authors said they expected further research to identify “a substantial number of additional common variants” that impact age of menopause, and that many of them will be located in genes identified in their study. The study examined more than 50,000 women of European descent who had experienced menopause between the ages of 40 and 60.

The research team noted that a large-scale study of menopause onset in African-American women is underway, which will help to determine whether the genetic variations that affect menopause onset in African-American women are similar or substantially different for women of primarily European descent.

Besides Lunetta and Murabito, senior authors on the study include: Anna Murray, a senior lecturer in genetics at the Peninsula Medical School in Exeter (UK); and Jenny A. Visser, a scientist at Erasmus Medical Center in Rotterdam (Netherlands).
