The Michigan Cancer and Research on the Environment Study, or MI-CARES, is largely motivated by Michigan’s history of toxic environmental exposures and environmental injustice, said Sara Snyder, the project director.

Researchers are recruiting 100,000 ethnically diverse, cancer-free Michiganders ages 25 to 44. It’s a statewide survey, but they’ll focus enrollment on what they’ve identified as six major environmental injustice hotspots: the Detroit metropolitan area, Saginaw, Lansing, Kalamazoo, Grand Rapids and Flint, Snyder said.

Environmental injustice refers to people who belong to groups that are discriminated against and are disproportionately exposed to contaminants and other health hazards.

June 1 marked the soft launch to test the website used to recruit candidates. People enroll every day, but the study’s full launch was earlier this fall.

A first in Michigan

“Nothing like this has been done in the state of Michigan before, which is almost shocking if you know about the levels of environmental injustice that have taken place,” said Lilah Khoja, a doctoral student at the University of Michigan on the MI-CARES team.

“There isn’t a community in Michigan that hasn’t been impacted in some way by environmental injustice,” she said.

It dates back decades: the PBB contamination of dairy products in the 1970s, the Flint water crisis, industrial pollution in Detroit and now PFAS, or per- and polyfluoroalkyl substances, nicknamed “forever chemicals” because they don’t break down in the environment, Snyder said.

The project, funded by the National Cancer Institute and the University of Michigan, will track participants through annual questionnaires for at least six years, Snyder said.

 

They’ll be asked about employment and residential histories, race, ethnicity, major health and life events and overall lifestyle to gauge participant health and previous exposures to industrial chemicals or other contaminants, Snyder said.

 

Beyond cancer, the surveys might also shed light on how exposures to chemicals in the environment cause heart disease, asthma or even Alzheimer’s disease, said Dana Dolinoy, the principal investigator of biomarker evaluations for MI-CARES.

Compiling the data needed for change

Such surveys have a proven track record. For instance, cancer rates are significantly higher in Flint compared to the rest of Genesee County and the state after lead contaminated the city’s water supply.

“My cousin, my aunt, my friend have all died of cancer,” said Arthur Woodson, a Flint resident and community activist. “People are dying in high numbers here of cancer.”

Such anecdotal reports can be reinforced by hard data produced by health studies from the Genesee County Health Department proving elevated cancer levels in the area.

A study recently published in JAMA Network Open found that 1 in 5 Flint residents have presumptive major depression and another 1 in 4 have presumptive post-traumatic stress disorder (PTSD).

“They fixed the water, but they didn’t fix the people,” Woodson said.

Providing people with the data they need

A large goal of MI-CARES is to give people access to data that will help them advocate for a cleaner environment and a healthier life, Khoja said.

“You can’t advocate for change if you don’t have the numbers to show that this is why it needs to change,” she said.

Cancer-centric studies like this one, whether linking it to smoking, a lack of physical activity or poor diet, played a role in a 29% drop in cancer death rates between 1991 and 2017, according to the American Cancer Society.

 

MI-CARES’ data will help improve Michiganders’ health while informing policy to reduce environmental injustices and harmful exposures, Snyder said.

 

Researchers looked at what was going on in the state and narrowed the study’s focus to the most prominent of the 80,000 chemicals in the environment: exposure to metals, like lead, chemicals in personal care products, air pollution and PFAS, Dolinoy said.

Addressing the issues

Michigan has the highest known PFAS levels of any state.

To measure some contaminants like lead, participants from the six environmental injustice hotspots will send in blood and saliva. These measurements, called intermediate biomarkers, show if a past environmental exposure changed the epigenome – the instruction book telling genes how to behave – to make them more susceptible to cancer and other diseases, Dolinoy said.

The study focuses on a younger population so that researchers might recognize any diseases before they manifest, Dolinoy said.

 

“This gives us time to intervene and treat individuals, because when the disease is already on board, it’s really hard to reverse it,” she said.

There’s evidence, though, that relatively easier things like changes in lifestyle and diet might reverse changes to that epigenetic instruction book, especially early in life, Dolinoy said.

Building a better tomorrow

The hope is to inspire policy intervention with MI-CARES findings, forcing industry and other institutions responsible for poisoning the environment to change. That is a challenge that the health survey hopes to meet.

“It’s very difficult to translate some of this science in a way that will directly change the economics of a company,” Dolinoy said. “But studies like MI-CARES can provide a weight of evidence that shows our environment can negatively contribute to disease status.”

New software enhances the study of animal ecology

“The underlying motivation of our work and research is always inquisitiveness and wonder at animal ecology,” said Stacy DeRuiter, professor of mathematics and statistics at Calvin College. “We can learn so much about creation by exploring.”

 

DeRuiter has for years studied marine animals, using bio-logging technology.

 

Recognizing a need

 

“Bio-logging studies, where data on animal movements are collected using small, animal-borne devices that either store or transmit sensor data, are growing rapidly in numbers and in scope,” said DeRuiter.

 

As the technology advances, there are more opportunities to track longer and more frequent data sets of animal behavior. Instead of tracking the animal once every few seconds, researchers are now receiving feedback multiple times a second. However, this means there is much more data to account for and sort through, explained DeRuiter.

 

“While these tags offer exciting opportunities to observe animal behavior in unprecedented detail, there is a desperate need for freely available, easy-to-use, flexible tools to facilitate proper analysis and interpretation of the resulting data,” DeRuiter said.

 

Developing accessible and efficient software

 

“We thought it would be worthwhile to spend a year making better software that would be more accessible, as well as creating documentation and a workshop to make it easier for people to use in general,” she said.

 

Throughout summer 2017, DeRuiter led a collaborative project developing software tools for analysis of data from animal-borne movement-sensors. Her team included two students, who developed tools and delivered a workshop at the University of St. Andrews in Scotland, introducing researchers to the tools and providing hands-on practice.

 

Before DeRuiter made the proposal for the project she received more than 30 letters from other researchers, who would benefit from her work, in support of the idea.

 

“It was amazing having the support of the community that really wanted this to happen but either did not have the time or funding to make it possible,” she said.

 

Gaining meaningful experience and connections

 

This project allowed students to develop some meaningful connections with influential researchers, explained DeRuiter.

 

“That is part of the reason I wanted them to come to Scotland and the University of St. Andrews,” she said. “They had done such great work and software development, and I wanted them to see the workshop play out.”

 

“The thing I enjoyed most was participating in the international workshop at the end of the summer,” said David Sweeny, a student researcher. “It was amazing to see how many different kinds of research topics from around the world are using the software functions that we have developed and translated.”

 

Sweeny said he is interested in this research because it gives him an insight into the lives of magnificent marine creatures during the times and in places that he otherwise would not be able to observe were it not for tags.

 

“This research provides so many ways to learn how we can best protect these animals,” he said. “Given that I care a lot about protecting the environment, this work is really important to me.”

 

Opening the door to future research

 

“One of the most important things that the Reformed tradition tells us about being Christian is that we don’t do it alone; we do it in community. Science, for example, proceeds by the careful work of many, many hands,” said DeRuiter. “The goals of the project were to democratize this kind of research and level the playing field for those who don’t have the same mentorship, training, or funding to buy software.”

 

This software will help DeRuiter track whale and dolphin behavior as well as open the door for other researchers to non-intrusively explore other animal habits.

 

“The availability of this software will only enhance the efficiency and effectiveness of current and future work being done around the world,” said Sweeny. “It will allow for increased collaboration between scientists which will have many different kinds of benefits in the future.”

Symposium creates community for those affected by rare disease

One in ten people is affected by a rare disease in some way, explained Rachael Baker, professor of chemistry and biochemistry at Calvin College. “Because there are 7,000 different rare diseases, everyone is probably going to know someone, a friend or family member with a rare disease at some point,” she said. “We want to raise awareness about what that looks like.”

Rare diseases and real stories

On March 3, 2018, Calvin and the Rare Disease Research Group will hold the first Rare Disease Symposium. This event will provide individuals the opportunity to learn about current research efforts in rare diseases that affect members of the local community. It will also allow local patients and their families to talk about living with rare diseases. February 28 is Rare Disease Day. Across the country on that day, people gather to recognize rare diseases.

 

“We wanted to have our symposium as close to rare disease day as possible,” said Baker.

 

“In West Michigan currently there does not seem to be any sort of rare disease community,” said Amy Wilstermann, biology professor. “There are families in the area that are affected by rare disease, people doing research on rare disease, medical professionals that are treating patients, and we have a lot of our students that are headed into medical professions. The goal of the Rare Disease Symposium is to bring all of these people together so that they can talk to one another and build some support networks and connect people to resources that they might not even be aware of.”

A community for those affected by rare disease

“Rare diseases are very important for just understanding health and the human body, but we didn’t want our students to only think of them in that context,” said Baker. “We wanted them to have a bigger vision for who is affected in this community and understand how can we speak to and minister to those people as we research.”

 

“Being sick is not a unique experience, but having a rare disease is,” said Baker. “When you have a rare disease, you’ve probably never heard of it before, you probably don’t know anyone else who has had it before, your doctor has probably never even diagnosed it before.” In the case of one of the symposiums’ speakers, their child is the only person in the world who has this specific disease. Things like ‘How will the disease progress as my child ages?’ is an open question for many families.

 

“Because of those factors, it can take a long time to get a diagnosis, and once you get a diagnosis, it can feel very isolating,” said Baker. “But, there are some very common emotions and experiences that are shared by many families that are diagnosed with rare diseases even if they don’t have the same rare disease. We think it is important to help them gather together and meet each other.”

A space to connect and learn

“Studying rare diseases is really important to me, because as a Christian I place a lot of importance on being a steward of all God’s people, especially the ones who are in the minority,” said Kalina Reese, a biochemistry and music double major, assisting in the symposium’s planning. “This experience has made me seriously consider the availability of disability research and the importance of making public areas accessible to those with diseases and disabilities.”

 

“I think the symposium fits into Calvin’s mission in a lot of ways,” said Wilstermann. “We are thinking about acting justly and living wholeheartedly.” In the rare disease community, because there are so many rare diseases that so few people have, there is not a big emphasis on research, she explained.

 

“I think one of the ways we feel that we are living out the mission is seeking out some of those areas of God’s kingdom that are neglected and devoting time to them.”

 

“We are hoping a lot of students attend the Rare Disease Symposium,” said Wilstermann. “Many will be working with people who are affected by rare disease at some point, and I would hope that they get a greater sense of the prevalence of rare diseases and understand the challenges, but also the resilience of some of these families at the event.”

 

“If someone comes in from the community who has a rare disease or is caring for someone that does, I hope they walk away from the symposium seeing Calvin as a new resource,” said Baker. “We are hoping the symposium will be the beginning of new relationships with a lot of community members affected by rare disease.”

 

The Rare Disease Symposium is free and open to the public. Attendees are encouraged to register for the event online.
