Canadian Network for Maternal, Newborn and Child Health Conference: Adolescents identified as a priority population

Written by Kaitlin Patterson, PhD Candidate

cesarkateThis week I attended the Canadian Network for Maternal, Newborn and Child Health Conference in Montreal. The focus of the panels and discussions was the 3 Ps: Partnerships, Policy, and Progress. Discussions ranged from how and which policies can support the achievement of the sustainable development goals (in particular those related to maternal and child health, and gender equality), successes and lessons learned in programming and partnerships, and pathways for the future. I was also delighted to run into an IHACC and CCIFS3 collaborator Dr. Cesar Carcamo from the Universidad Peruana Cayetano Heredia. It was really great to connect with him and take a token IHACC pic!

Open Letter Re Muskrat Falls

PDF Copy of Letter

Re: Open Letter on Government of Newfoundland and Labrador’s Decision on Muskrat Falls

As professors and health researchers who have had the great privilege and pleasure of working in the Nunatsiavut region of Labrador for almost a decade, we are writing this open letter to express our perspectives on the recent decisions to not act on scientific evidence to remove organic materials (topsoil, vegetation, and trees) from the Muskrat Falls reservoir and surrounding area.

Under the current development scenario, not only will there be dramatic environmental alterations in an area that is historically and culturally significant to the Indigenous Peoples of Labrador, but research indicates that people in the region will be exposed to methylmercury well above regulatory guidelines from Health Canada and the United States Environmental Protection Agency. The science is clear: without removing organic material from the site to be flooded, methylmercury levels in the Lake Melville ecosystem are anticipated to significantly increase, leading to contamination of important country food sources in the region, and leading to increased methylmercury exposure for Indigenous peoples in the region reliant on these food sources. Methylmercury exposure can have harmful health impacts: scientific literature and medical studies show that long-term dietary exposure to methylmercury is linked to brain development problems in children and can damage the nervous system in adults; and children who are exposed while they are in the womb can have deficits in cognitive thinking, memory, attention, language, fine motor skills, and visual spatial skills.

It is a cultural right of Inuit and Indigenous peoples in the region to continue to rely on the land for sustenance, livelihoods, and food security, as their ancestors have for thousands of years. To disrupt important keystone food sources such as fish and seal, and render them inedible and harmful to human health, causes serious impacts to food sovereignty in the region and impacts cultural continuity, history, and heritage. Furthermore, this is a human rights issue – the right of Indigenous peoples in the region to continue to enjoy harvesting from the land for food security, culture, and wellbeing. As such, there is a human responsibility to respond based on the best available scientific evidence and Indigenous science and oral history. Economic compensation will never fully compensate for the loss of food security and cultural wellbeing that comes from actively engaging in land-based activities – activities that have sustained Indigenous people in Labrador for thousands of years. There will also be continued health and social disruptions, leading to increased healthcare costs for physical and mental health issues, and further needless financial burden on individuals, communities, and the government.

Mitigation is possible. The future of how this development continues can still be altered. There is still the opportunity to #MakeMuskratRight. There is still the opportunity to value human and environmental life and health above pressures of a large crown corporation, funded by tax payers, and follow the precautionary principle to ensure the continued survival – and thriving – of the First Peoples of Labrador who will experience the downstream effects.

As scientists and scholars, we stand in solidarity with the Nunatsiavut Government and their recommendations for the removal of trees, vegetation, and soil before flooding and for more environment-health monitoring and management with Inuit partnership. We also stand in solidarity with Indigenous peoples of Labrador, with Inuit Tapiriit Kanatami, and with all the concerned citizens and organizations who have expressed concern and condemnation for this development, and call for immediate evidence-based action to support human and environmental health, and for stronger, more respectful, and more authentic Nation-to-Nation relationships.

Emily Meets With The Honourable Elizabeth Dowdeswell

Written by Emily Nunez, Undergraduate Thesis Student

emilyIn mid-September, I received an e-mail from Janet Doner, Manager of Community Engagement and Global Citizenship at the University of Guelph, inviting me to be part of a small group of students to have a conversation with the Lieutenant Governor of Ontario, Elizabeth Dowdeswell. Her Honour had specifically requested to meet with a group of students who are engaged in a variety of initiatives on and off-campus, and I was fortunate enough to have been recommended by staff and faculty members.

Carlee Attends “Water Innovations for Health Arctic Homes”

Written by Carlee Wright, MSc Candidate

Anchorage, Alaska | Sept 18-21, 2016

September has been a non-stop month full of school-related travel, and I am very fortunate to have recently returned from the Water Innovations for Healthy Arctic Homes (WIHAH) conference in Anchorage, Alaska ( The Arctic Council Sustainable Development Working Group has endorsed a project titled “Improving Health through Safe and Affordable Access to Household Running Water and Sewer in Arctic and Sub-Arctic communities”, with the WIHAH conference comprising one of its objectives.

This conference was a vital opportunity for community members, professionals, and researchers from the United States, Canada, and Greenland to come together and discuss all aspects of drinking water in northern communities. Despite being developed nations with high overall service rates for household water and sewerage, many people living in rural and remote areas experience lower service rates, and face issues with accessing clean water in adequate quantities. Over 3000 homes in rural Alaska do not have any piped water, and instead rely on honey buckets and hauling drinking water home from central watering points in the community. Collection and storage of drinking water in containers also occurs in Rigolet, Nunatsiavut (The community with which I have worked), and so I was very interested in attending presentations and sharing my own research with such a diverse audience.

Over the 4-day program I was able to meet Alaska natives, economists, microbiologists, engineers, health researchers, and many others who were passionate about improving access to safe water in northern communities. Hearing about the realities of living without running water in some communities, and the immense resources required to provide water and sanitation services was overwhelming at times; however, it was also inspiring to hear success stories and learn about innovations and progress being made. For example, the Alaska water and sewage challenge ( is a competition to develop affordable and sustainable water and waste systems that can be implemented in rural Alaskan villages (and hopefully other communities in the future). The challenge is down to three finalists, who unveiled their prototypes at the conference; I was even able to see a functioning prototype at the University of Alaska Anchorage campus!

Finally, a trip to Alaska cannot be complete without some outdoor fun, and so my trip concluded with a day cruise through Prince William Sound. It was a misty day (which happened to make everything look even more astonishing under the low-lying clouds), and although I have yet to see a moose on my two trips to Alaska, I was lucky enough to see bald eagles, belugas, otters, and orcas while out on the water. Getting so close to glaciers and appreciating their size and natural beauty is also something that I am not likely to forget any time soon!

This conference was an amazing opportunity to reconnect, make new acquaintances, learn, and think critically about water management and the future of water and sanitation in northern communities. For this I am incredibly grateful, and in the future I hope that I can continue to take part in more collaborative and transdisciplinary events such as WIHAH.

When in Rome, learn about epi!

Written by Julia Bryson

At the tail end of the summer I had the exciting opportunity to attend the annual congress of the International Society on Environmental Epidemiology (ISEE) in Rome, Italy. The title of the conference, “Old and new risks: challenges for environmental epidemiology,” set the tone for what was to be a productive meeting of researchers, experts, policy-makers, public health professionals, and students coming together to discuss the identification and mitigation of environmental hazards to health, from past to future.

Upon arriving, I was quick to notice that the proportion of students amongst the attendees was quite low. Needless to say, as an undergraduate student in a crowd of seasoned experts and renowned researchers, I felt decidedly ‘out of my league’. However, I came to realize that everyone was there to learn, and while I had more of that to do than others, my participation and abilities were not to be discounted by my relative lack of experience. With this in mind, I tackled the three packed days ahead.

Over the weekend, I was happy to discover that the conference featured several parallel sessions and posters on the impacts of climate change on human health; these provided me with valuable information and perspective as I pursue my systematic review investigating the influences of climate change on the neglected tropical diseases in East Africa. Many of these researchers have faced the same barriers that I am dealing with, including the dearth of research in populations of low socioeconomic status and the sometimes lacking quality of data collected in unstable, resource-poor populations where conditions are hard to control. It was encouraging to see others working through these obstacles and forming important conclusions that may help to shape policy for future.

It came as a surprise to me, but the discussions around policy and ethics in environmental epidemiology were perhaps most engaging and valuable to me as a new student in the field. These talks ranged in topic from the role of the epidemiologist in the justice system, to the ethics of data sharing and communication with the public. Provocative questions were posed that I had never considered, such as ‘How do we reconcile the definition of “significant” in the field of research (often set at a level of 5% or 1% probability that results are due to chance), with that of the legal system, where a 51%-49% split or ‘more probable than not’ is the accepted standard?’ and, ‘How do we balance the demands of policy-makers and the public for results now with the reality that epidemiological studies often take years to complete?’ These questions forced me to think critically about the issues at hand and they exposed me to new philosophies and challenges within epidemiology. It was also reassuring that for these questions everyone in the room was having trouble coming to a solution! Some fascinating debates resulted.

Without doubt, I came away from ISEE will many ‘big ideas’ about this field of research. I learned that in epidemiology, there is always the need for more research as populations and exposures change. I learned the importance of understanding how to convey risks transparently and with context when your ultimate audience is the public. I learned how significant community health policy partnerships are to ensuring that research is able to facilitate positive change, which often happens outside of the lab through the courts or government. My attendance also helped to highlight areas for growth, particularly my understanding of different epidemiological methodologies and analytical models. A stronger foundation in these areas will help me to improve my comprehension and appreciation of others’ work, and better understand how I can strengthen my own research.

In the end, it sometimes seems like I left this conference with more questions than I arrived with. But in many ways, that was one of my aspirations! I attended ISEE 2016 to expose myself to different areas in epidemiology, to challenge myself with new concepts, and to be inspired as I move forward with my research. I am happy to say that my attendance accomplished these goals and more. I have no doubt that what I have learned as a result of this experience, and what it has encouraged me to learn about in the future, will be of great value. And with that – Ciao, Roma, e grazie mille per tutti!

People, Animals, Water, and Sustenance (PAWS) project: Update from Iqaluit

Written by Anna Manore, MSc Candidate

It’s a beautiful, sunny, summer day in Iqaluit, Nunavut, and a dozen rambunctious sled dogs are happily barking and jumping around. Three researchers from the University of Guelph are moving among the dogs, stooping and scooping to collect the stool of these rambunctious animals.

This isn’t just a community service – the three researchers are collecting dog stool in order to detect infectious diseases that could pose a danger to humans. Danielle Julien, Stephanie Masina, and Anna Manore are three graduate students whose work on the PAWS (People, Animals, Water, and Sustenance) project aims to shed some light on potential sources of enteric illness in Iqaluit. Cryptosporidium and Giardia are the two pathogens of interest, and the PAWS project is investigating dogs, surface water, and clams as potential sources for these two potentially harmful protozoans.

“PAWS is a great example of taking a systems approach to health and social issues,” says project manager Anna Bunce, from McGill University. “This is important because it gives us an holistic understanding of a number of issues and how they fit together to create the contemporary context of Iqaluit.”

EcoHealth and OneHealth approaches are being used to guide this project forward, which, in the words of Danielle Julien, offers “an incredible opportunity to work together with fellow researchers from various disciplines within our department [Department of Population Medicine] to accomplish an understanding of health in the North”

“This project couldn’t be done without our wonderful collaborators from the Nunavut Research Institute, Jamal Shirley and Jean Allen,” says Stephanie Masina. Jamal, Jean, and Stephanie have been sampling surface water since the beginning of June, at sites where local residents gather drinking water.

Anna Manore’s project, which will be looking at clams, is gearing up for sample collection to begin in the Fall. “It’s been so helpful being in Iqaluit, being able to meet people and ask questions, and to get feedback on what might or might not work in terms of sampling. Of course, helping out with the dog sampling is a big plus!”

The PAWS team hopes that their work, as a whole, will provide new understanding of the sources of enteric illness in Iqaluit, and inform potential future public health interventions.


Collaborative Arctic Summer School in Epidemiology (CASE): Alaska 2016

Written by Vivienne Steele, Anna Manore, and Carlee Wright –  MSc Candidates

It is night time here at Land’s End, on the Homer Spit – yet it is still light out. The Homer spit is about 5 hours from Anchorage; it juts out into the bay for 7km and is full of tourist shops and restaurants selling fresh-caught fish and chips. Land’s End is located (surprise!) at the end of the spit, with many boats coming and going from the harbour at all hours of the day for fishing trips. The sea surrounds the hotel, with mountains all along the horizon and a volcano in the distance, too. What a place!

Anna, Carlee, LJ and Viv spent the weekend in Anchorage prior to the beginning of CASE’s 2016 Arctic Epidemiology course. Based on recommendations from locals, Anna, Carlee and Viv went for a day’s hike to Flattop Mountain. We took our time making it up to the clouded summit, seeing great views of Anchorage, the ocean, and mountains all around. The last 30 minutes of the hike were tough, requiring ‘crawling’ up by selecting the best rock-stepping options and grabbing other rocks to pull oneself up. Great views at the top. Another highlight was a walk past the Ulu museum, where the river in town hosts many salmon passing through. Always cool to see people fly-fishing and catching the big ones!

On Sunday we met with the Russian participants and headed to Land’s end via shuttle, arriving in time to enjoy a welcome dinner with the Alaskan hosts and several of the Amercian students. This was a great opportunity for us to make introductions and enjoy a casual evening together.

On Monday, we settled into the classroom for official introductions with the students and faculty, and met up with the Norwegians, as well as Lindsay and Jen Jones who had arrived late from Whitehorse! The morning was full of engaging talks: birth registries in Norway and Georgia, how to compare health data globally (including some weaknesses of WHO data!), the role of contaminants in birth cohort studies, as well as stories of Salmonella enteriditis and Hanta virus outbreaks from a member of the CDC. Anna and Carlee gave their presentations in the afternoon, and got great questions and advice from those in attendance! The day’s food highlights included clam chowder and salmon pâté, as well as a dinner of elk meatloaf and seafood tortellini alfredo. It is special to see “nightfall” from our hotel room – the sun appears to go down, but it never really gets dark!

On Tuesday, the organizers asked if anyone had seen the otter giving birth on the beach that morning – apparently otters move from water to shore while in labour. Over lunch break, we were able to check out the golden eagle perched right outside of the classroom window, who is apparently caring for its newborns. We had some great sessions including a talk about drinking water and rural sanitation, how to pass your PhD, and more student presentations (including Jen Jones). In the afternoon we headed out- halibut fishing time! It took 2 hours to boat to the fishing site, and during that time we enjoyed views of endless mountains, the volcano in the distance, sea otters, eagles, and all-around great weather! We all dropped our lines and were reeling in halibut within 5 minutes. Most of us caught 2 and stopped, but some of us kept going until a dozen or so had been caught and released. Finally, we all packed it in while the deck hands got to work filleting the fish – did you know that the halibut’s cheek is its tastiest part? Next, the captain took us to Gull Island, which houses approximately 20,000 birds in high nesting season, with some years lacking even an inch for birds to nest, as each is taken by other birds. We saw pelagic cormorants, sea gulls, black-legged kittiwakes, murrs, puffins, immature bald eagles and a golden eagle. During the day, we also saw many otters, humpback whales, and a harbour seal! A late evening walk along the ocean brought us more sea otters, some kelp, and the desire to run out into the very chilly water. We settled into the hot tub immediately after.

Wednesday was spent in the classroom, with student presentations from Lindsay and Viv, as well as an interactive lecture on spatial analysis given by Dr. Philippe Amstislavki. Dr. Andy Gilman also facilitated a great session in the afternoon; students were divided into groups of community members, scientists, and public health officials in an interesting role-playing scenario to demonstrate challenges and opportunities in risk communication. In the evening, we went into town to enjoy the fish that we had caught the day before – much halibut for all – fried, baked and roasted – delish!

By Thursday, many of us were feeling the effects of a long week, but there was still much to do and see! After talks on breastfeeding and occupational health in Alaska (where we learned about aviation safety and some of the truths behind the TV series “The Deadliest Catch”), LJ presented her proposed PhD work on sense of place and birth experiences in Pond Inlet. After lunch, we heard a great talk on leadership from Dr. Linda Chamberlain, who used inspiring anecdotes and metaphors about her dog-mushing team before giving us all an afternoon tour of her Husky Homestead! We visited the dogs and learned a lot about the history of dog sledding and the Iditarod, with many sleds, harnesses, fur coats, fur mittens and photos around for us to admire.

On Friday, the course was wrapped-up with talks on obesity in Alaska and tips on acing academic presentations, as well as each person sharing a word that they felt reflected their CASE experience (see word map). After the return drive to Anchorage, many of us met for dinner at the famous Moose’s Tooth Pub & Pizzeria. Overhead, planes (large and small) took off and landed constantly. Although it was past 10pm, it was still very bright out, and we made it back to the hostel in time for a good night’s rest.

On our last day in Anchorage, we had a big breakfast to fuel a 25-mile bike ride along the coastal trail, which was fantastic! Anna took charge of the map and guided us along the trail, which detoured past the international airport and the Spenard Lake floatplane base (the largest in the world!). There were hundreds of planes parked in the water, and constant air traffic overhead. We lay on the grass to watch 747s take off above us, and didn’t have to wait long! Although Carlee had hoped to see a moose, and many Alaskans say they see them often along the trail, we weren’t so lucky. We returned our bike rentals by mid afternoon and headed back to the hostel to pack up and take a taxi to the airport. Although we have enjoyed the land of the midnight sun, we are all secretly looking forward to falling asleep under a dark starry sky back home in Guelph. Thank you to all of the organizers of CASE 2016 for a rewarding, engaging, and unforgettable experience in Homer!
