3D imaging could improve outcomes for breast cancer patients – CTV News London

Published

 on


LONDON, ONT. —
Researchers are investigating digital breast tomosynthesis, a type of 3D imaging, to see if it’s better at detecting breast tissue abnormalities than the 2D mammography regularly used today.

The study is being conducted by Lawson Health Research Institute.

Current practice uses digital 2D mammogram, which uses two x-ray images of the breast, one from top-to-bottom and another from side-to-side at an angle.

This technology is limited by the overlapping breast tissue, which occurs due to the required compression of the breast, and can leave some breast abnormalities hidden.

A tomosynthesis exam is relatively new technology in which the x-ray tube moves in an arc over the compressed breast and captures multiple images from different angles. The images are then reconstructed into a set of 3D images by a computer.

By being able to examine the breast at multiple layers of depth, the radiologist is better able to distinguish normal breast tissue from potential tumours.

This method could be especially useful for women with dense breast tissue.

To determine whether this newer 3D method is more superior than the conventional 2D exam, researchers are conducting a study which will Include approximately 165,000 participants from centres across Canada, the U.S. and Argentina.

Participants will undergo either an annual or biennial screening frequency, depending on their risk factors for breast cancer, for approximately four years.

Then participants will undergo long-term follow-up for at least three more years.

Advocates call for COVID-19 vaccination plan for migrant and undocumented workers – Airdrie Today

Published

 on


TORONTO — Migrant and undocumented workers must have access to the COVID-19 vaccine as part of Canada’s immunization effort, advocates said Wednesday, calling on all levels of government to ensure the workers are guaranteed the shots.

The Migrant Rights Network, along with doctors and labour groups, voiced concerns that thousands of migrant and undocumented workers may not get the vaccine because of their immigration status.

“Concrete action is urgently necessary to ensure life-saving public health measures are accessible to all migrant and undocumented people,” said Syed Hussan, spokesman for the group.

An estimated 1.6 million people in Canada don’t have permanent resident status and many work in essential jobs in health care, construction and agriculture, the group said.

While governments have said the vaccine rollout will be universal, the advocates made specific recommendations to ensure the workers receive the shot.

Granting workers permanent resident status would address the problem, but in the absence of that the group recommended vaccines be provided to the workers free of charge and without a health card required to obtain them.

Advocates also said the shot shouldn’t be mandatory and health-care providers must train people providing the doses to ensure migrant or undocumented workers aren’t turned away.

Dr. Danyaal Raza, chairman of Canadian Doctors for Medicare, said many undocumented workers are afraid to get the shot because they worry about having to provide identification. 

“Many uninsured people with precarious status worry about being reported to the Canadian Border Services Agency to face detention or deportation,” he said. 

“Some, as a result, may avoid receiving the vaccine altogether. We need to be able to assure those affected that their privacy will be respected.”

Pauline Worsfold, a registered nurse with the Canadian Federation of Nurses and chair of the Canadian Health Coalition, said migrant workers cannot be included as an “afterthought” in the country’s vaccine rollout.

If Canada’s goal is to eliminate COVID-19, as many people as possible must be vaccinated, she said.

“They must have access to universal health care immediately, regardless of their immigration status, and it should be private and confidential so that we can eliminate the COVID virus and the variants that are now spreading like wildfire,” she said.

A spokeswoman for the Public Health Agency of Canada said COVID-19 vaccines across the country are being administered for free.

“While they’re available to priority populations first, they’ll be available to everyone in Canada who is recommended to get the vaccine by federal, provincial and territorial public health authorities,” Anna Maddison said in a statement. 

“This applies to everyone in Canada, including those who aren’t citizens.”

Maddison said that each province is in charge of its own plan to administer the vaccine. 

In Ontario – where thousands of migrant workers arrive to work on farms every spring – a spokesman for the  Ministry of Health said the government’s goal is to provide a shot to everyone who is eligible and wants a vaccine.

“When temporary workers get vaccinated depends on where they fall in the priority framework,” David Jenson said in a statement. 

“You do not need an (health) card to receive the vaccine. If you do not have an (health) card, you may bring another form of a government issued-photo ID.”

This report by The Canadian Press was first published Feb. 24, 2021.

B.C.'s COVID-19 death count stays low, as vaccination roll-out stays slow – Powell River Peak

Published

 on


Health officials identified two people who died from COVID-19-related causes overnight, after one such death was recorded the day before. While that raises the province’s death toll from the virus to 1,338, the three deaths in two days is the lowest two-day total since November 5 and 6, when there were two COVID-19-related deaths identified. 

This good news is partly because 98% of seniors in care homes have been vaccinated, provincial health officer Bonnie Henry told media yesterday. She called the success of the vaccine in older people “miraculous.”

Nonetheless, B.C.’s roll-out of vaccines continues to be slow, with only 6,521 doses being administered in the past 24 hours. There were 2,809 additional people who got a vaccine dose in the past 24 hours, and 3,712 doses went to people as a second dose. 

In total, 230,875 doses have been given to 168267 people, with 62,608 people getting second doses. Starting in March, if around four million eligible British Columbians remain unvaccinated, the province would have to vaccinate about 19,000 people per day in order for all of them to be vaccinated by the end of September. 

“Just as our health-care system has risen to the challenge of protecting and caring for people who have become ill with this virus, so too are countless others working hard to get people immunized as quickly and safely as possible,” Henry and Health Minister Adrian Dix said in a joint statement. 

“Vaccinating our entire population is a monumental task that must account for the diversity of our geography and our population. We must consider how to safely deliver vaccine to rural and remote communities, how to connect with seniors and elders everywhere, and how to ensure the process to get immunized is as simple as possible. We are pushing hard right now, and we must continue to balance speed with the need for careful thought and planning.”

There were 456 newly identified infections in the past day, down by 103 from yesterday. A total of 78,278 people in B.C. have contracted the virus since officials detected the first case on January 28, 2020.

The vast majority of the 4,668 people actively battling infections have been told to self-isolate, although 237 are in hospital, with 64 of those inflicted seriously enough to be in intensive care units. 

More than 92.2% of those infected in B.C., or 72,219 individuals, are considered to have recovered because they have tested negative for the virus twice. Another 7,924 people are being closely watched by health officials for symptoms because they have had known exposure to at least one identified case.

Here is the breakdown of where the 456 new cases are located:
• 108 in Vancouver Coastal Health (23.6%);
• 259 in Fraser Health (56.7%);
• 35 in Island Health (7.6%);
• 30 in Interior Health (6.5%);
• 20 in Northern Health (4.4%); and
• four people who regularly reside outside Canada.

There were no new healthcare facility outbreaks in the past day, according to Henry.

The outbreak at the seniors’ home Creekside Landing in Vernon has been declared over, Henry and Dix said. 

The number of outbreaks at seniors’ homes has dwindled significantly since January, when there were more than 50 outbreaks for much of the month. 

There are now only 11 outbreaks at those homes, with none of those being in the Vancouver Coastal Health region. 

The five active outbreaks at seniors’ living facilities in Fraser Health are:
• CareLife Fleetwood in Surrey;
• Fleetwood Villa in Surrey;
• George Derby Centre in Burnaby;
• Royal City Manor in New Westminster; and
• Shaughnessy Care Centre in Port Coquitlam.

Two outbreaks at seniors’ homes in Nanaimo – Eden Gardens and Wexford Creek – are the only ones in the Island Health region.

The outbreak at the Acropolis Manor in Prince Rupert is the only active outbreak in Northern Health. 

The three active outbreaks at seniors’ living facilities in Interior Health are at:
• Brocklehurst Gemstone Care Centre in Kamloops;
• Noric House in Vernon; and
• The Florentine in Merritt.

The list of B.C. hospitals with active COVID-19 outbreaks includes:
• Burnaby General Hospital in Burnaby;
• Dawson Creek and District Hospital in Dawson Creek;
• Kelowna General Hospital in Kelowna;
• Mission Memorial Hospital in MIssion;
• St. Paul’s Hospital in Vancouver; and
• Vancouver General Hospital.
