Christian Medical College: Ida Scudder’s legacy to the Vellore community

Dr Ida Sophia Scudder – the founder of Christian Medical College (CMC), Vellore – breathed her last sixty years ago on this day. But her life and legacy continue to inspire hundreds of thousands across the world. An American by origin, Dr Ida spent her lifetime uplifting the community in Vellore through her medical practice. Her work is never more relevant than now when we are facing a pandemic. In this article, I have attempted to highlight some of the contributions of Dr Ida Scudder,  and others, which continue through CMC, Vellore. 

It would be hard to believe that the town which once greeted medical officers, who tried to vaccinate people to contain the plague, with sticks and stones would later be the first in the country to be polio-free. The person whose life and legacy was mainly influential in bringing this change was a woman physician by name, Ida S. Scudder. Dr Ida Scudder and the professionals at the medical college she founded – Christian Medical College (CMC) – transformed the community in Vellore to what it is today.

CMC, Vellore, is renowned globally for its many achievements in the field of medicine. One of the major contributions of the medical college, through which the legacy of Aunt Ida continues, is its community service. From Dr Ida Scudder’s efforts in containing the plague outbreaks to Dr Paul W Brand’s accomplishments in rehabilitating lepers and Dr T Jacob John’s leadership in eradicating polio and containing HIV/AIDS, CMC’s services to public health have not only impacted Vellore and India but has also influenced the world.

It all began one night at Tindivanam, Tamil Nadu, when 20-year-old Ida Scudder encountered a life-changing incident. Three men – a Brahmin, an upper-caste Hindu, and a Muslim – approached Ida seeking help for their wives who were in labour. Ida explained that she had no medical training, but her father who was a missionary doctor could help them. But none of them would agree. In Ida’s words, the Brahmin drew himself up and said, “Your father come into my caste home and take care of my wife! She had better die than have anything like that happen.” The Muslim also responded with similar words saying, “She had better die than have a man come into the house.” Ida could not sleep that night. She wrote about this incident later, “Within the very touch of my hand were three young girls dying because there was no woman to help them.” She spent the night in anguish, torn between a great life in America and the need to serve the people in India. Ida had come to Tindivanam only to take her ailing mother back to the USA. Until that night, she wanted to enter Wellesley College and “continue in the happy free life of a young woman in America.”

The next day, Ida sent a servant to check what had happened to the three women only to hear that all of them had died the previous night. She shut herself in the room. After much thought and prayer, Ida told her parents that she wanted to go home and study medicine to come back and help such women in India.

In 1895, Ida entered the Women’s Medical College of Philadelphia. It was a time when women were not welcome as qualified surgeons and doctors. Three years later, when Cornell opened its doors for the first time for women students of medicine, Ida transferred there for better opportunities. As Mary Pauline Jeffrey writes in her biographical account of Ida Scudder, some students at Cornell often “did things to make women feel that they were foreign bodies.” Nobody would have imagined then that about 50 years later, Ida would be admitting male students to the Women’s Medical College she founded at Vellore!

On January 1, 1900, Dr Ida Scudder landed in India. She started running a clinic in a 12*8 feet room at her house. Meanwhile, she worked toward realizing the hospital for which she had received a donation of $10,000 while in the USA. In 1902, the 40-bedded Mary Taber Schell Memorial Hospital opened. Her vision was that women should have equal access to quality healthcare as men, regardless of their religious or socio-economic status. In 1909, Dr Ida established a school of nursing and in 1918 she established a medical college for women. The medical college was called Missionary Medical College for Women. In 1945, it was renamed as Christian Medical College and in 1947 CMC opened its doors to male students.

The tiny clinic and the hospital thus grew to be the medical college that would have many firsts to its credit. Dr Ida was deeply connected with the community she lived in – a legacy that the medical college would become renowned for. This was never more relevant to us than now. In 1903, when the plague hit Vellore, as many as 17 people were dying every day. In 1904, the total number of cases in India had reached 1,100,000 before preventive measures showed any sign of success. At that time, along with the municipal commissioner, Dr Ida “sallied forth to grapple with the deadly epidemic. Into the homes of the community in Vellore these two went, enforcing sanitary measures and administering prophylactic inoculations.”

Half a century from then, Dr Paul Brand carried that torch making another mark in the community in Vellore. Realizing his life’s calling at CMC, Dr Paul established the New Life Center at Vellore to rehabilitate lepers and dispel the stigma that prevailed even among medical professionals. Dr Paul also performed the world’s first reconstructive surgery on leprosy patients at CMC, Vellore.

A couple of decades later, Vellore became the first town to eradicate polio. An alumnus of CMC, Dr T. Jacob John led the initiative of making Vellore polio-free and later headed the national efforts in eradicating polio. In his own words in conversation with the journal Current Science, “Globally, Vellore was the centre conducting such basic and problem-solving research on polio from the mid-1960s.” Dr Jacob John headed the virology services at CMC from 1967-1995. During this time, he also played a key role in India’s efforts to contain HIV/AIDS.

Dr Ida Scudder’s legacy continues through the work of CMC. The medical college has produced some of the best doctors, surgeons and scientists in the country, who have been recognized for their work.  Of special note in the context of public health, epidemiology and community medicine are experts like Dr Gagandeep Kang, Dr T. Jacob John, Dr Jayaprakash Muliyil and others.

At this time, when the country is faced with an epidemic, Dr Ida Scudder’s legacy serves as a reminder of what empathy, compassion and boldness can help one achieve. It is her legacy that we need now – of providing quality and compassionate healthcare for all sections of society.

The Nobel winners, 2019: Physician-scientists who discovered how cells adapt to changing oxygen levels

The Nobel Prize in Physiology or Medicine, 2019 was awarded to Gregg L. Semenza, William G. Kaelin Jr. and Peter J. Ratcliffe and for their work on how cells sense and adapt to oxygen availability. Their research elucidated the genetic mechanisms through which cells respond to changes in oxygen levels. The findings have implications in treating many diseases, including cancer, anaemia, heart attacks and strokes. These scientists had also shared the Albert Lasker Basic Medical Research Award in 2016.

If Semenza, Kaelin and Ratcliffe had one thing in common, besides their area of research, it is that they chose to publish houses of brick rather than mansions of straw. It sure took a while for the world to notice them, but it did.

About the papers that earned him the Lasker, Kaelin wrote, “Most would be considered quaint, preliminary and barely publishable today.” These papers would get him the Nobel Prize three years later.

Semenza and Kaelin woke up to the call from the Nobel media that day. While Semenza’s first reaction was to hug his wife, Kaelin told Adam Smith – the Chief Scientific Officer of Nobel media – how he missed his late wife on that occasion. Ratcliffe, on the other hand, was working on a grant when Smith called him. “I was writing and will continue to write an EU Synergy grant for collaborative work with friends and colleagues in Finland, and also my good friend and colleague Christopher Schofield, so of course the EU’s on our minds at the moment, and we’re writing a Synergy grant. And despite this good news, I guess I’ll continue doing that and meet the deadline,” Ratcliffe said.

What made these scientists embark on their journey in research is worth knowing. In an interview with The Journal of Clinical Investigation (JCI) in 2016, Semenza said that it was his high school biology teacher, Rose Nelson, who inspired him to pursue biology. “I had her as a freshman for biology and then as a senior for AP biology when it was genetics within biology that I got really excited about. With her help, I was able to enrol in an NSF-sponsored summer program at the Boyce Thompson Institute for plant research. It was really my first exposure to research and experiments,” he said. His interest in genetics and his meeting with a family friend’s child, who had Down syndrome, motivated him to pursue MD-PhD to study genetics and to care for those with genetic disorders.

It wasn’t easy for him at this stage either. Being the first graduate student of the lab with a very ambitious project in hand, he had reached the stage where he felt it wasn’t working out. He then switched to another lab at Children’s Hospital of Philadelphia in the second year, where he studied β-thalassemia.

“I was tasked with studying an unusual family, where one of the alleles was a silent carrier,” Semenza told JCI. “Normally, you can tell from looking at the blood cells whether someone is a carrier. In this case, it was the father who was an obligate carrier, as he had two affected children, but you couldn’t tell he was a carrier. It was suggested that the mutation was in some way different; this was going to be my project. The idea was that you take the blood, isolate the DNA, make a library, pull out the β-globin gene, and sequence it. I did all that and at the end of one year, I got the sequence, and the mutation was the exact same mutation as the previous study, which meant that somehow the clone had become contaminated, and the whole thing had been for nothing. So now I was going to have to start over the third time. I went back, started over again; things went smoothly because technically I’d already done it, and we went through the project and got an answer.”

He then moved to Johns Hopkins for his post-doctoral education, where he worked with Haig Kazazian and Stylianos Antonarakis – leaders in finding the molecular basis of β-thalassemia. He started working on this gene called Erythropoietin (EPO), which Chuck Shoemaker from Genetics Institute in Cambridge had asked Kazazian and Antonarakis to consider. Semenza tried to identify the DNA sequences in the gene responsible for its expression in different tissues. They put different fragments of human DNA spanning the EPO gene into mice and checked if and where the gene was expressed.

This was the turning point for Semenza. He figured that the gene was regulated by oxygen. Now, he had to understand where these DNA sequences regulated by oxygen were located. On investigating further, he realized that this sequence was in the DNA sequence that came after the gene (3’ flanking sequence). This was unusual as such regulating regions usually lie before the gene (5’ flanking sequence). But the data said that it was the 3’ flanking sequence. So, they took this sequence and put them in a plasmid which had a reporter. They then put this plasmid inside human cells grown in the dish and deprived them of oxygen. At low oxygen levels, the EPO gene would be expressed because of the sequence present in the plasmid. They then made smaller fragments of that sequence and repeated the process until they got down to 33 base pairs. On mutating individual nucleotides in this region, they found that the EPO gene expression was stopped.

“We suspected that there was a very important factor, which was binding to that sequence and was responsible for turning on the gene. And so, we tried to find the protein that was the key factor for turning on the EPO gene,” Semenza told JCI.

At this point, he was a young faculty with a post-doctoral fellow, Guang Wang. Semenza and Wang started looking for a protein that would bind to this DNA sequence (Hypoxia Responsive Element). The challenge was to figure out the conditions that allowed binding. They were also hoping to find something that would be present in the nucleus of cells with low oxygen (hypoxic) but absent in those with normal oxygen levels (normoxic). “Guang would do several of these experiments a day and had this stack of blots with negative results on his desk. I was thumbing through them one day, and I came across this one gel where there seemed to be a faint band in the hypoxic lane. I got all excited and said, ‘Did you see this? Did you see this?’ After optimizing the assay in a very short period of time, he generated really strong definitive results of a binding activity that we called hypoxia-inducible factor 1,” Semenza said.

For Ratcliffe, the start was serendipitous. In his Lasker acceptance speech, Ratcliffe reflects on an incident from his days at the Lancaster Royal Grammar School for the boys. “I was a terrible schoolboy chemist and following the career of some distant relative, I was keen to study industrial chemistry. One day the ethereal but formidable headmaster appeared in the chemistry laboratory, summoned me to one side, and said, ‘Ratcliffe, I think you should study medicine.’ I said ‘Yes, Sir’ decisively. Without further thought, the university application papers were changed accordingly,” he said. “To this day, I don’t really know whether he felt I would be a good doctor or a bad chemist. But the moment sticks with me as a reminder of the importance of serendipity in a scientific career, at least in mine,” he added.

He trained in Medicine as a Kidney specialist and started his research career fascinated by the extraordinary sensitivity with which the kidneys regulate the hormone Erythropoietin (EPO) to regulate red blood cell production. “I felt that the problem was interesting, conceivably attractable and there was a new opportunity for study with the cloning of the erythropoietin gene. But some people felt, with the emerging success of recombinant Erythropoietin, that understanding how the hormone was regulated was a niche area unlikely to be of very general importance. They advised me accordingly to study something else,” he said.

In the telephone interview with Nobel Media, Kaelin shared what drew him to science. “You know, I’m a big believer of curiosity-driven, hypothesis-driven research,” he said. “I know that’s complementary to other ways of generating knowledge but I think in the end what drew me to science and what draws a lot of scientists to science is that we like interesting puzzles, like clinical features of patients who had mutations in the VHL gene, were a curious constellation of findings but one way to unify them was there was some abnormality in the way the tumours they were developing were sensing and responding to oxygen, and we thought if we could understand that we could understand more globally how cells and tissues sense and respond to changes in oxygen.”

Little did these physician-scientists know while addressing their research problems, that they were reaching for the Nobel with their findings. But that’s the beauty of Science. Think about these Nobel laureates. As someone who made a serendipitous entry into medicine later pursuing an area of research, which many thought had no scope beyond the niche area of kidney research, Ratcliffe won the Nobel Prize for the findings that have immense physiological importance. Sharing the award with him are Semenza, who struggled in the early days of PhD and found his way through, and Kaelin, whose pre-medical school mentor remarked on his college transcript, “Mr. Kaelin appears to be a bright young man, whose future lies outside of the laboratory.” Their life and work are a testament to the fact that houses of brick stand the test of time.

The little joys of life

Escalator   kids wonder

One city that will stay close to my heart for a lifetime is the city of Chennai. It has given me memories and experiences some of which I will cherish for a very long time. Although I went to Chennai with the intent of being trained to be researcher, the city taught me many more things. From financial management to disaster management, Chennai gave me some extra coaching.

What I am about to tell you is a small incident that I witnessed in Chennai. It is something that we might just shrug off, but somehow it stayed in my heart.

On one of the extended weekends, I was heading home from Chennai. As I got off the suburban train and made my way to the central railway station, I saw a little boy and his excitement about life. As I followed the crowd that waited to get on the escalator, I heard him shout in excitement “Look Dad, the stairs are moving! We don’t have to climb them, they’ll do it for us!” He kept repeating it as he stood on the escalator, amazed at the way it worked.

I stood behind the kid and wondered about the little joys that we have in life. Remember the day you stepped in an elevator for the first time? Or used a smartphone or a social network? Didn’t we all have that excitement in us? Over time, with progressive acquaintance, we tend to lose that sense of wonder. We get bored of it. The same things that once filled us with excitement turns out to be regular and unexciting. That is why it is important that we absorb things slowly in life. That will help us sustain the sense of wonder. When such exciting things come our way, let us relish it, for these are the little joys of life – the spice in our savory!
