OTTAWA — A Canadian company is telling the government today that its trials of a potential COVID-19 vaccine on animals completely blocked the virus, but it must conduct human trials to know whether it has found a possible cure for the pandemic.

And a leading health-care expert says the findings are promising even though they haven’t been peer-reviewed.

Providence Therapeutics says it needs federal funding to move forward, but it has not heard back from the Trudeau government since May, the month after submitting a $35-million proposal to conduct first-stage human trials.

Providence has told the government it could deliver five million doses of its new vaccine by mid-2021 for use in Canada if it were able to successfully complete human testing, but it has heard nothing.

Eric Marcusson, the San Francisco-based co-founder of Providence and its chief science officer, says the company has concluded testing on mice that showed its vaccine was able to block the entry of the novel coronavirus into their cells.

Successful tests in animals can provide proof of the concept behind a potential new medicine or vaccine before trials in ever-larger groups of human subjects determine how well the drug works in the body and whether it has harmful side-effects.

Trials in humans are expensive and usually time-consuming.

Mario Ostrowski, the University of Toronto professor of medicine and immunology whose laboratory performed the animal trials, said he supports the results and says they are on par with tests of vaccine candidates from the American pharmaceutical firm Moderna and Germany’s BioNTech.

All three companies use the same new mRNA vaccine technology and last week, Moderna began a 30,000-person human trial after receiving hundreds of millions of dollars from the U.S. government.

The U.S. has also committed to pay Germany’s BioNTech and its American partner Pfizer $1.95 billion to produce 100 million doses if their vaccine candidate proves safe and effective in humans.

The mRNA vaccine technology involves using a key fragment of genetic material instead of working with an inactive sample of live virus.

“We have been testing the prototype vaccine in animal studies,” Ostrowski told The Canadian Press. “When we give the vaccine to mice, it is safe and makes a very strong immune response and very potent antibodies.”

Ostrowski said that the strength of the antibodies found in the mice appeared to neutralize the virus better than other similar vaccine candidates have at the same testing stage.

“Another point is that the Providence vaccine is very similar to the Moderna vaccine in the U.S. and the German (BioNTech) vaccines, both showing excellent results,” added Ostrowski, who practices at St. Michael’s Hospital in Toronto.

Brad Wouters, the executive vice-president of the Toronto-based University Health Network, said he has seen the new Providence data and it looks promising, but it needs to be peer-reviewed.

“The fact that the vaccine has created neutralizing antibodies means that the mouse immune system is reacting to the vaccine and producing antibodies that block the ability of the virus to infect cells,” Wouters said in an emailed response to questions.

“This suggests the results are better than even they were expecting.”

But Wouters added that the Providence data needs a full peer review, and that under normal circumstances he wouldn’t even be commenting publicly on research at this stage unless it were accompanied by a published peer review.

“This is the normal and correct way for this to happen. But as you have seen, COVID-19 is breaking traditions and they (Providence) are certainly not the first to release information from experimental research in advance of publication,” said Wouters, who is also the senior scientist at the Princess Margaret Cancer Centre.

Alberta Sen. Doug Black has urged Ottawa to fund Providence so it can develop a domestic COVID-19 vaccine to lessen the risk Canadians will have wait in line for a foreign-made pandemic cure.

Several health-care professionals have also written to Innovation Minister Navdeep Bains to urge him to make up his mind on the Providence proposal.

The company plans to release the results publicly on Wednesday at the same time it delivers them to several relevant government departments.

“We’re still blocking the virus 100 per cent. Nothing gets in,” Marcusson said in a telephone interview from San Francisco, where he has been living in lockdown since March as the pandemic exploded in California.

“There’s no doubt this vaccine needs to be tested in humans because the results in mice are really that exceptional. This has the chance to be an extremely effective vaccine, but we won’t know for sure until we get into humans,” he said.

Marcusson is a 20-year veteran of the American biotechnology sector and had founded his own consultant business before meeting Providence chief executive Brad Sorenson in 2014. The two founded Providence in 2015 to develop cancer vaccines but it has pivoted to COVID-19. Marcusson said 20 per cent of his work remains outside the company as a consultant.

Black and several health experts say the government must move forward with a made-in-Canada vaccine because there have been troubling signs that a vaccine produced abroad likely wouldn’t be available to Canadians until much later.

Canada has already funded a the partnership between China’s CanSino Biologics and Dalhousie University in Nova Scotia but China has held up shipments of the vaccine that it was supposed to send to Dalhousie researchers by the end of May to start human trials.

“They’ve already been burned a couple of times with masks not getting across the border from the U.S. and a vaccine that they helped fund not getting into the country because it was held up at customs in China,” said Marcusson.

“So, this is a vaccine that can be made in Canada for Canadians,” he added. “It would be nice if that wasn’t important, but it is important, and they need to realize this and fund a Canadian solution to this problem.”

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Pediatric group says doctors should regularly screen kids for reading difficulties

Published

 on

 

The Canadian Paediatric Society says doctors should regularly screen children for reading difficulties and dyslexia, calling low literacy a “serious public health concern” that can increase the risk of other problems including anxiety, low self-esteem and behavioural issues, with lifelong consequences.

New guidance issued Wednesday says family doctors, nurses, pediatricians and other medical professionals who care for school-aged kids are in a unique position to help struggling readers access educational and specialty supports, noting that identifying problems early couldhelp kids sooner — when it’s more effective — as well as reveal other possible learning or developmental issues.

The 10 recommendations include regular screening for kids aged four to seven, especially if they belong to groups at higher risk of low literacy, including newcomers to Canada, racialized Canadians and Indigenous Peoples. The society says this can be done in a two-to-three-minute office-based assessment.

Other tips encourage doctors to look for conditions often seen among poor readers such as attention-deficit hyperactivity disorder; to advocate for early literacy training for pediatric and family medicine residents; to liaise with schools on behalf of families seeking help; and to push provincial and territorial education ministries to integrate evidence-based phonics instruction into curriculums, starting in kindergarten.

Dr. Scott McLeod, one of the authors and chair of the society’s mental health and developmental disabilities committee, said a key goal is to catch kids who may be falling through the cracks and to better connect families to resources, including quicker targeted help from schools.

“Collaboration in this area is so key because we need to move away from the silos of: everything educational must exist within the educational portfolio,” McLeod said in an interview from Calgary, where he is a developmental pediatrician at Alberta Children’s Hospital.

“Reading, yes, it’s education, but it’s also health because we know that literacy impacts health. So I think that a statement like this opens the window to say: Yes, parents can come to their health-care provider to get advice, get recommendations, hopefully start a collaboration with school teachers.”

McLeod noted that pediatricians already look for signs of low literacy in young children by way of a commonly used tool known as the Rourke Baby Record, which offers a checklist of key topics, such as nutrition and developmental benchmarks, to cover in a well-child appointment.

But he said questions about reading could be “a standing item” in checkups and he hoped the society’s statement to medical professionals who care for children “enhances their confidence in being a strong advocate for the child” while spurring partnerships with others involved in a child’s life such as teachers and psychologists.

The guidance said pediatricians also play a key role in detecting and monitoring conditions that often coexist with difficulty reading such as attention-deficit hyperactivity disorder, but McLeod noted that getting such specific diagnoses typically involves a referral to a specialist, during which time a child continues to struggle.

He also acknowledged that some schools can be slow to act without a specific diagnosis from a specialist, and even then a child may end up on a wait list for school interventions.

“Evidence-based reading instruction shouldn’t have to wait for some of that access to specialized assessments to occur,” he said.

“My hope is that (by) having an existing statement or document written by the Canadian Paediatric Society … we’re able to skip a few steps or have some of the early interventions present,” he said.

McLeod added that obtaining specific assessments from medical specialists is “definitely beneficial and advantageous” to know where a child is at, “but having that sort of clear, thorough assessment shouldn’t be a barrier to intervention starting.”

McLeod said the society was partly spurred to act by 2022’s “Right to Read Inquiry Report” from the Ontario Human Rights Commission, which made 157 recommendations to address inequities related to reading instruction in that province.

He called the new guidelines “a big reminder” to pediatric providers, family doctors, school teachers and psychologists of the importance of literacy.

“Early identification of reading difficulty can truly change the trajectory of a child’s life.”
