Singapore - Biomedical Research Will Become Asian Research


Singapore — A plate of worms; a blood-pressure cuff sitting on a table near a housing project; an endoscope used to peer into the stomach.

All are emblematic of the wide variety of Asian research I got a glimpse of in four days of interviews here.
Why do so many scholars think that the 21st century will be the Asian century? The answer isn’t just that many Asian universities are racing to be research powerhouses. Depending on the country, there’s as much stumbling as there is running.

A different answer is that the focus of biomedical research, by virtue of population alone, will have to shift to Asia. About 4.1-billion of the planet’s roughly seven-billion people live in Asia. Demographic shifts in the Asian population will shape research: China’s one-child policy and family-planning programs promoted in many other Asian countries, for instance, have led to a larger proportion of the Asian population being elderly, with fewer young people to take care of them.

The blood-pressure cuff and the plate of worms are symbols of aging research. I saw a blood-pressure cuff on a table in an open-air pavilion near a government-housing project in Singapore, where researchers were trying to help the elderly manage their own health care. As for the worms, some National University of Singapore scientists are using a popular research model, C. elegans, to find out why some worms age well and others don’t. The worms, unlike humans, are genetically identical, so differences cannot be blamed on genes. Graduate students gaze through microscopes at plates of worms to find the ones that are aging well.

Gastric cancer may not seem, at first glance, to be an exciting research topic. But consider this: Early detection could mean the difference between just having the stomach lining removed through a small incision rather than major surgery to take the whole stomach out. Older Chinese men are disproportionately affected by gastric cancer. “It’s very much an Asian disease,” says Wei Peng Yong, a senior consultant at the National University Cancer Institute in Singapore.

The researcher who can come up with a good test that finds those in the early stages of the disease could spare millions of people the risks of major surgery, and the subsequent effects of having to live without a stomach.

Once in Hong Kong, a university administrator drove me past three tall apartment buildings clustered next to each other. He told me more than 900,000 people lived there. That’s when it clicked for me: One highly contagious, lethal virus on an elevator button and a lot of people could die. In addition, scientists understand that as Asian urban areas expand out into rural, agricultural ones, more infectious agents could make the jump from animals to humans. Emerging infectious diseases have been an early focus of Asian research.

In Singapore, I met a few researchers working on infectious diseases. One was Vernonika Von Messling, a German-trained veterinarian who has spent time at the Mayo Clinic and a research institute at the University of Quebec, and who is interested in respiratory viruses, including those that cause the flu. For her, one of Singapore’s attractions is the ease of working with pigtail macaques, a monkey from Southeast Asia that, were she working in North America, would need to be imported and quarantined.

Focusing on bacteria and viruses alone is never enough, though. Ultimately, how health care is organized drives the delivery of medical treatment, and studying that delivery often falls to social scientists.

Sometimes Asian countries have shied away from supporting social scientists, for fear that their research would be critical of governments. That is changing.
Eric A. Finkelstein, a health economist, says that when he moved to the Duke-NUS Graduate Medical School in Singapore from the Research Triangle Institute, in North Carolina, he was the second health economist in the country. He is interested in the “economic causes and consequences of health behaviors.”

He originally thought his job change would be a step down, but he wanted to try living in Asia. After two and a half years here, he doesn’t feel that he made a bad move: In 2012 alone, he has 15 papers published or forthcoming. Despite just a short time abroad, Mr. Finkelstein feels that he has been instantly labeled “global” and that his career has gained cachet.

Singaporean health care is organized differently than in the United States, and those differences can shed light on consumer choice, Mr. Finkelstein has found. Singaporeans with health-savings accounts that contain both their own money and employers’ contributions seem to have less interest in spending that money on expensive late-stage cancer treatments, for instance, and as a result, utilization of those treatments is lower in Singapore.

Across Asia, researchers like Dr. Von Messling and Mr. Finkelstein are building informal, “bottom up” coalitions of researchers on many topics so they can share everything from tissue samples to ideas. Western researchers not involved in the region risk being on the outside of those networks, looking in.
