Avian Flu outbreaks 'concerning,' say U of G experts – GuelphToday

The following article was provided by University of Guelph news services.

The discovery of a “highly pathogenic subtype” of avian influenza across the globe and in Canada is worrisome, say University of Guelph experts.

They’re concerned that an uncontrolled spread of the new subtype lays the groundwork for a potential human flu pandemic. 

Shayan Sharif is an immunologist in the Department of Pathobiology in the Ontario Veterinary College, who specializes in the immune systems of chickens, including their responses to the avian influenza virus – also called the avian flu. He is also the associate dean of research and graduate studies.  

As a data scientist in the School of Computer Science in the College of Engineering and Physical Sciences, Rozita Dara studies applied artificial intelligence, data governance and information privacy with a focus on disease modelling and digital agriculture.  

Because the flu subtype is currently spreading in both wild and domestic bird populations, there are concerns that the viruses will mutate or exchange genetic material. That’s something over which researchers have “very little control” and that could prolong the risk, said Sharif.  

“Beyond that point, there isn’t evidence of the subtype spreading to humans, but if we have massive circulation of highly pathogenic viruses in our flocks, the chances for gaining such ability by the virus will enhance significantly,” he said.  

“In that case, we might run into yet another pandemic.” 

Previous human influenza pandemics have had links to viruses originating from avian species, he noted.  

Although the cause of the current outbreak is uncertain, he posits climate change may have impacted “the habitat for migratory birds and as a result caused novel viruses to emerge. 

“This is the reason the WHO (World Health Organization) and other health or veterinary organizations are monitoring things very carefully.” 

The Canadian Food Inspection Agency (CFIA) has implemented strict biosecurity measures for the infected Canadian farms, their neighbours and regions.  

The full response, though, depends on the scale of the outbreak. If the responses continue to be timely, the impact will be minimal, but if not, then other measures will be put in place. Some of the current and future measures will include culling and testing birds and limiting movements between farms, said Sharif.  

But there may be a more effective and efficient way to monitor and control the outbreaks. 

With Sharif and other colleagues, Dara is using social media and open data sources such as the geographical distribution of migratory bird species to build a surveillance system for the early detection of avian influenza.  

That tool, said Dara, would not replace the existing practices but would help to “make more informed decisions in a shorter amount of time.  

“Time plays a key role in avian influenza management. Ad hoc collection, aggregation, and analysis of outbreak data is time consuming, and may result in delay in implementing control measures. Surveillance systems can enable near-real time access and processing of outbreak data.”  

Using artificial intelligence to analyze historical tweets and past avian flu outbreak information enables outbreak prediction in a region.  

“These systems can help health authorities and emergency responders to assess risk and mitigate disease emergencies more quickly. They can enhance the speed of reactions as they can bypass the formal information channels,” said Dara. 

That way, she added, emergency responders can decide about control strategies, such as whether farmers need to monitor animal health conditions (through testing) or limit movements among farms.  

“As organizations and individuals use social media more actively, the feasibility of building surveillance tools for real-time and early detection of disease outbreaks will improve,” she said.

Health-care announcements expected with two weeks to go in N.B. election race

Published

 on

 

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

Published

 on

 

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

Published

 on

 

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.
