Study reveals living in wildfire-prone areas may cause health concerns
The first-of-its-kind study found higher rates of lung cancer and brain tumours in people exposed to wildfires across Canada, including in B.C.
The study, published in The Lancet Planetary Health, shows that people living within 50 kilometres of wildfires over the past 10 years had a 10 per cent higher incidence of brain tumours and 4.9 per cent higher incidence of lung cancer, compared to people living farther away.
Scott Weichenthal, associate professor in the department of epidemiology, biostatistics, and occupational health at McGill University, said wildfires tend to happen in the same locations each year, which means long-term exposure.
The authors note that the research is important because projections indicate there will be greater fire activity fuelled by climate change in the future.
That has been borne out in B.C. with three of the most extreme fire seasons taking place within the past five years.
In the 2021 fire season, more than 520 building were burned, mostly people’s homes, and 32,000 people had to evacuate. Two people were killed in a wildfire that destroyed the Village of Lytton in the B.C. Interior. In 2017, another extreme wildfire season, 65,000 people had to evacuate their homes.
A Postmedia investigative series published in the past week that examines what’s needed to prepare for forecast more extreme wildfires and floods, found the costs of wildfires are significantly underestimated because tabulations do not include damages to health and the environment.
Wildfires are increasingly recognized as a global health problem, stressed researchers.
“Many of the pollutants emitted by wildfires are known human carcinogens, suggesting that exposure could increase cancer risk in humans,” says Jill Korsiak, a PhD student in Weichenthal’s lab who led the analysis.
In addition to impacts on air quality, wildfires also pollute aquatic, soil, and indoor environments. While some pollutants return to normal concentrations shortly after the fire has stopped burning, other chemicals might persist in the environment for long periods of time, including heavy metals and hydrocarbons.
The study could have implications for governments’ efforts to lessen wildfire emissions and for individuals’ efforts to limit exposure, for example, by using indoor air filters, said Weichenthal.
Because of the first-of-its-kind study’s limitations, the researchers said further work is needed to refine the data used in estimating the chronic health effects of wildfires, replicating the study in different geographical locations and populations and further examining the effects of wildfire pollutants in soil, water and house dust.

Health-care announcements expected with two weeks to go in N.B. election race
New Brunswick‘s Liberal and Green parties are set to make announcements about health care on the campaign trail today as the provincial election race enters its second half.
Liberal leader Susan Holt is scheduled to hold her announcement this morning in Saint John, N.B., followed by lunch at the city’s market.
A spokesperson with the Progressive Conservative party shared few details about the event scheduled for leader Blaine Higgs in Fredericton this morning.
Green Party Leader David Coon will hold a news conference this morning about “local health-care decision-making” alongside deputy leader Megan Mitton in her Sackville, N.B. riding.
On Saturday, Coon said he was proud to put forward a gender-balanced slate among the party’s 46 candidates.
While the Liberals and Progressive Conservatives are running with full slates, the Greens are three candidates short and will not have full representation when the province’s residents go to the polls on Oct. 21.

Alberta Health Services’ snag leads to potential delay of patient referrals
EDMONTON – The Health Quality Council of Alberta is investigating how some medical referrals weren’t properly processed, potentially affecting 14,000 patients over the last five years across the province.
The referrals were made to specialists outside of Alberta Health Services, such as physiotherapists and dietitians.
The health authority’s CEO, Athana Mentzelopoulos, says it does an average 100,000 referrals per year, but in some cases it can’t confirm if patients received referral services.
She says the problem was flagged in late September, and a preliminary estimate suggests 31 patients may have experienced a potential negative outcome due to the delays.
The provincial government requested the investigation, and the quality council is to find out how the snag occurred and how it can be prevented in the future.
The health authority says it has begun notifying patients who may have been affected by the disruption, and the cases could date back to 2019.

Don’t fall for fake dentists offering veneers and other dental work on social media
WASHINGTON (AP) — If you have stained or chipped teeth, you might be considering veneers, customized teeth coverings that can restore a photogenic smile without more extensive dental work.
But dentists warn that these pricey cosmetic enhancements are at the center of a worrisome online trend: unlicensed practitioners without proper training or supervision offering low-cost veneers.
These self-described “veneer techs” often promote themselves on Instagram and TikTok, promising a full set of veneers for less than half of what dentists typically charge. Some also market their own training courses and certifications for people looking to get into the business.
It’s misleading, health professionals warn — and illegal. All states require dental work, including veneers, to be performed under the supervision of a licensed dentist.
On Thursday, Georgia law enforcement officials arrested Brandon Diller, who promoted himself to 158,000 Instagram followers as “Atlanta’s top veneer specialist and trainer.” Diller practiced dentistry without a license and sold “training and certificates, which were worthless” and “provided no legitimate or legal credentials,” according to an arrest warrant from Fulton County’s District Attorney’s office.
Here’s what to know about veneers and how to avoid bogus providers and services:
What are dental veneers?
Veneers are thin, custom-made dental coverings used to hide minor imperfections or to fill in gaps between teeth. Unlike crowns or more invasive dental implants, veneers are almost always considered cosmetic dentistry and generally aren’t covered by insurance.
Dentists usually charge between $1,000 and $2,000 per tooth for veneers, with higher prices for those made from porcelain compared with lower-grade materials.
Placing veneers involves stripping some of the natural enamel from the tooth and bonding the new covering into place. Because of that process, getting veneers is considered an irreversible procedure, according to the American Dental Association. They are not permanent, and can be expected to last between 5 to 15 years before they degrade and need to be replaced.
In recent months the ADA has been stepping up warnings about the risks of veneer procedures done by unlicensed individuals.
“Quality control is lost without the involvement of a licensed dentist,” said Dr. Ada Cooper, a New York-based dentist and ADA spokesperson. “We undergo years of education and training and need to be licensed by various regulatory bodies before we can practice.”
What are the risks of getting veneers from someone who isn’t licensed?
Improper veneer procedures can cause a range of health problems, including severe pain, nerve damage and tooth loss.
Patients need to be anesthetized before the enamel is removed from their teeth.
“It could be incredibly painful if they’re not anesthetized correctly,” said Dr. Zach Truman, who runs an orthodontics practice in Las Vegas. “You can also go too deep into the tooth and penetrate what’s called the pulp chamber, which contains blood vessels and nerves.”
One of the biggest problems Truman sees with unregulated veneer work is that customers aren’t getting screened for existing dental problems, such as gum disease and cavities.
“If you put a veneer on a tooth that has an active cavity, you’re just going to seal it in there and eventually it’s going to progress to tooth loss,” Truman said.
Dental veneers aren’t the only option for improving the appearance of teeth. Over-the-counter whitening kits can help with minor stains and discoloration. And dentists can sometimes use composite materials to reshape chipped or uneven teeth. But Truman says those fillings are prone to crack and won’t last as long as veneers.
How can I spot bogus veneer providers online?
One clue: Many individuals performing unlicensed dental work promote themselves on social media as “veneer technicians.”
Instead of working out of a dental office they often perform treatments at beauty salons, hotel rooms or private homes. Some advertise multi-city tours and encourage clients to message them to book an appointment in advance.
Much of the appeal of the services is in their pricing, with some offering a full set of veneers for a flat fee of $4,000 or $5,000. That’s less than half of what patients can generally expect to pay at a dental office.
Performing dental work without an appropriate license is illegal, the ADA notes.
Dentists and hygienists are licensed by state governments, who also define the work dental assistants can perform. But in all cases, veneers and other dental procedures must be supervised by a licensed dentist.
Earlier this year, Illinois law enforcement officials arrested a woman running a business called the Veneer Experts after she posted videos of herself fitting braces, veneers and other dental products without a license. She was previously arrested in Nevada on similar allegations of practicing dentistry without a license.
What are the best ways to find legitimate dental providers?
The ADA maintains a website detailing the training and licensing requirements for dentists across the U.S. Most states also maintain websites where you can lookup and verify licensure information and find any past disciplinary actions for dentists and other health professionals.
“It’s really critical to understand that dentistry is a regulated health care profession that requires formal educations and licensure,” Cooper said.
