Dal and NSHA researchers receive $1.1M from Government of Canada to study COVID‑19 – Dal News

Published

 on


Researchers from Dalhousie University and the Nova Scotia Health Authority are leading projects which received a $1.1 million investment from the Canadian Institutes of Health Research (CIHR) and Research Nova Scotia as part of a May 2020 Rapid Research Funding Opportunity.

The funding opportunity is a partnership between the CIHR, the International Development Research Centre (IRDC), the Michael Smith Foundation for Health Research, Alberta Innovates, the Saskatchewan Health Research Foundation, Research Manitoba, the New Brunswick Health Research Foundation, and Research Nova Scotia (RNS). It is supporting clinical trials, observational studies, implementation science and other relevant study designs to scale-up promising existing projects, reorient current research, and initiate new rapid response research to address COVID-19 in the identified research areas that include understanding the safety, efficacy, effectiveness, ethics and implementation of:

  • Vaccines, diagnostics, or therapeutics;
  • Clinical management and health system interventions; and
  • Social, policy, and public health responses and related indirect consequences

The announcement was made Thursday, June 25, 2020 by the Honourable Patty Hajdu, Minister of Health. A total of $109 million was invested in 139 research teams.

“We are very proud to have researchers from Dalhousie University continue to play a key role in the global response to the COVID-19 outbreak,” says Alice Aiken, vice-president research and innovation at Dalhousie. “The evidence they are building through their innovative work will aid in the design of economic and social policies and interventions that will help mitigate the significant impact of this pandemic.”

PUPPY Study – Problems Coordinating and Accessing Primary Care for Attached and Unattached Patients Exacerbated During the COVID-19 Pandemic Year: A Longitudinal Mixed Methods Study with Rapid Reporting and Planning for the Road Ahead

COVID-19 has caused significant changes in primary care. In Canada, many walk-in clinics and family practices have closed. Pharmacies remain open but with restrictions on patient interactions. Other major changes in care (e.g., virtual care, reduced referrals) have been made to respect public health and emergency orders. During these times with significant restrictions, patients can be unclear or unaware of how to get the right care, at the right time, from the right provider.

Understanding the rapid changes in primary care and how to navigate these is challenging for everyone, but more so for people without a regular primary care provider to help guide them. The proposed study builds on existing research with an experienced team. The team will work to understand critical gaps in primary care access and coordination by comparing data from before, during, and after the pandemic. Multiple sources of data will be used such as policy makers, primary care providers, patients, waitlist data, healthcare billings, and prescribing data. The results are critical for strengthening primary care during and beyond the COVID-19 pandemic.

Impact of the COVID-19 pandemic on Canadians living with mental illness, and their children

Deterioration of mental health may be the most serious consequence of the COVID-19 pandemic. Social isolation, reduced activity, lack of opportunities, unemployment and financial uncertainty are known triggers of depressive episodes and suicides. Those living with pre-existing mental illness, and their children, may be among the most vulnerable to the indirect consequences of the pandemic.

The healthy development of children depends on the health of their parents and children of parents with serious forms of mental illness are at increased risk of adverse outcomes. Now, with closed schools and reduced access to external resources, the wellbeing of children may be linked to the mental health of their parents even more tightly than before. This project will examine the exposure, coping and impact of the COVID-19 pandemic in over 1000 adults and children from 300 families, including 200 families where one or both parents are living with mental illness. Their findings will be used to inform public health strategies and mental health service provision and make them sensitive to the needs of families, including those where parents are living with mental illness.

“This funding announcement speaks to the excellence of our Nova Scotian researchers who have worked tirelessly to improve health care in the face of unprecedented challenges,” says Dr. Gail Tomblin Murphy, Vice President, Research, Innovation & Discovery and CNE at NSHA. “I am confident the work of Drs. Marshall and Uher will shape our understanding of COVID-19 as we continue to take a leading role in our national response.”

Dietary change during COVID-19: A population-based study in Atlantic Canada to build evidence for government economic and social policy responses

The CELLAR (COVID-related Eating Limitations and Latent dietary effects in the Atlantic Region) study, led by Dr. Catherine L. Mah, Canada Research Chair in Healthy Populations, will investigate the nutritional consequences of how we eat during the pandemic in Atlantic Canada.

COVID-19 is a looming nutrition problem and policy problem for the Atlantic provinces, where diet-related health risks are among the highest in Canada. The consumer food environment has been transformed by the COVID-19 pandemic. Many families and food system sectors are facing economic precarity of unexpected scale and duration.  

Through CELLAR, the research team will carry out an in-depth analysis of how COVID-19 is affecting Atlantic residents’ diets and nutrition. The results of CELLAR will produce much-needed regional evidence for social and economic policies that support healthy eating for all–during and after the pandemic.

Expression and Purification of COVID19 Virus Spike (S) Protein for Diagnostics and Vaccines

Dr. Richardson’s work focuses on the spike protein (S) of the coronavirus which mediates attachment and entry into the host cell and is the major target of neutralizing antibodies that block infections.  The first goal of this research is to generate large quantities of the S protein is a mammalian expression system that can be easily scaled up for large scale production. The protein generated in this procedure can be used to produce immune diagnostic kits as well as serve as a component of subunit vaccines or booster shots directed against COVID-19.

The second aim describes the generation of recombinant vesicular stomatitis (VSV) viruses that express the Spike (S) protein derived from COVID-19 virus. In the first experiments, VSV genome vector is modified to contain coronavirus S protein in place of its G glycoprotein which normally mediates attachment and entry of the host cell. The S protein changes the tropism of the recombinant virus and provides a new antigen target for the immune system.  VSV is highly attenuated in human cells and is tightly controlled by the host antiviral interferon system. It is also the vaccine vector for the highly effective Ebola virus vaccine. The diagnostic and vaccine reagents developed in this proposal will be distributed and tested by colleagues at the Canadian Center of Vaccinology (Halifax) and VIDO-InterVac Vaccine Cenre in Saskatoon.

The final aim is to use the reagents generated in the proposal to study cell receptors for COVID19 coronavirus and study infections in susceptible cells using model viruses of lower risk and pathogenicity.

Research Nova Scotia is providing support to other regional researchers who are working on a project led by the University of Alberta. Dr. Roy Duncan, Dr. Scott Halperin and Dr. Alyson Kelvin from Dalhousie University will rapidly develop, validate and clinically evaluate a novel DNA vaccine against COVID-19. Clinical trials will be initiated at the Canadian center for Vaccinology in Halifax within 8 weeks of project initiation, with the goal of a commercial release within one year.

“Research Nova Scotia was excited to partner with CIHR, IDRC, and other provincial funders to support regional COVID researchers working across the country,” says Stefan Leslie, CEO of Research Nova Scotia. “It is important that we support our researchers on these large-scale, national projects.”

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
