Stem Cell Therapies Banned by Health Canada

Indiscriminate bans could lead to patients being left with no options for their pain.

In May 2019, over three dozen clinics across British Columbia, Alberta, Ontario, and Quebec were ordered by Health Canada to cease and desist offering unapproved stem cell therapies. While this may seem like a reasonable regulation to prevent untested medical treatments being used on unsuspecting patients, many clinics, like Toronto PRP and Stem Cell, say that this ban is too broad and denies patients access to well-documented successful treatments.

The above video by the DISC Spine Institute – Dallas explains what adult stem cells are and how they can be harnessed for stem cell therapies.

Adult stem cell therapies have been shown in multiple studies to be effective for joint, ligament, and tendon injuries, such as osteoarthritis. Additionally, many patients who have undergone these “unapproved” stem cell therapies have noticed greater range of motion, less pain, and more functional abilities. With the new regulations, all similar treatments, except for certain blood cancers, such as leukemia and lymphoma, would only be available to a select few patients through clinical trials.

This ban does not come without good cause, however. Many private clinics have been advertising stem cell therapies as the ultimate panacea, offering it as a treatment for autism, multiple sclerosis (MS), ALS, and even hair-loss, when there have been no studies to prove their effectiveness in these conditions. Additionally, the nature of these therapies, while leading to long-term improvements, could also lead to long-term threats for those seeking these treatments. Health Canada states that many risks, such as infection by bacteria and viruses, patient cross-contamination, and even tumour formation, have been observed in unapproved stem cell therapies.

There is also a more sinister aspect to these unproven medications. Due to the thousands of dollars each stem cell therapy costs, there is a high risk of financial exploitation. Many private clinics who are capitalizing on the clout of a cure-all miracle drug are using stem cells for absolutely untested treatments, and gaining up to $15 000 per treatment. These sorts of advertisements depend upon the desperation of the sick and disabled and their families to make their living, and most doctors agree it has to stop.

At the end of the day, many believe that Health Canada had to do something about the unregulated use of stem cell therapies across Canada. However, there is also worry that those desperate enough to pay the high fees for these treatments would be willing to go to less safe clinics outside of Canada to undergo these treatments anyways. By slowly implementing restrictions, instead of this broad ban, Health Canada could have avoided this issue, as well as prevented the denial of viable treatments to patients in need.

Bringing Back the Dinosaurs

In November of 2018, Chinese CRISPR researcher He Jiankui sparked international outrage after announcing his experiment to create genetically modified twins using CRISPR. Despite what this event may seem to say about Chinese research ethics, China actually has strict regulations put in place to prevent incidents like these from occurring. They are also at the forefront of CRISPR research, using the genome editing tool in the agricultural industry to efficiently feed their massive population with restricted resources and space. The technology used in the twin experiment is also nothing new and mysterious. CRISPR is a well researched natural defense tool discovered back in 1993.

CRISPR, which stands for “clustered regularly interspaced short palindromic repeats”, uses a guide RNA to guide a separate piece of DNA to a specific target in the genome of a cell, where the Cas9 enzyme cuts the current DNA in place. The cell’s natural DNA repair machinery then heals the cut area with the DNA bound to the guide RNA, implementing the DNA into the genome. While there are other methods to edit the genome, CRISPR is relatively cheap, safe, and specific to it’s target.

The cause for concern should not be how little we know about this tool, but instead for how well we know it’s potential. The same tool that helps China grow better crops can also bring back the woolly mammoth or dinosaurs back from extinction. By extracting DNA from bones and other remains of extinct animals, Many species have had their genomes partially sequenced. These genomes can be cut and pasted into living animal cells, to bring about a new hybrid species with traits like the extinct species. Theoretically with a completely mapped genome, the extinct species can be brought completely back to life.

While it seems like a good idea to bring back certain extinct species, we should consider the effect it will have on our current ecological systems. These species were adapted to live in an environment from their time, but we now have different ecological ranges. We should also consider the factors that led to the extinction of that species. What measures will be put in place to prevent their extinction this time around, and what effect will the revival have on current species biodiversity?

Social Media! How Harmful can It possibly be?

It’s being preached about everywhere, having an online presence is directly associated with plummeting mental health… Right? As seen on platforms such as Instagram they have completely removed the ability to view the number of likes on another user’s post in efforts to stifle the issue. A similar matter is explored in the article written by Scientific American, concerning a study conducted by Jensen et al. ,on a group of young teenagers to determine if being in front of a screen has harmful effects on their mental health. To summarize, the study found no correlation with the duration of screen time and negative mental health. Furthermore, there was no negative effect if there was less time spent on screen either. However, the study did find that teenagers who exchanged more messages online were more likely to feel more connected to their friends, and generally happier. This study lacks expansion on what the teens are doing online as there are varieties of different outlets on screen. Ranging from video games, the browsing videos, to different social media platforms.

This then prods the question, if screen time is not the factor that is making teens more anxious and depressed, then what is? I feel that perhaps this study was not in depth enough because it did not measure what the teens were doing specifically. Perhaps if the study was conducted with different control group and there was a comparison between different control groups on varied media platforms, there would be a correlation found. 

A different look at this issue is presented by Bailey Parnell, who stresses that social media does having long lasting implications on society. She expands that over 70% of Canadians use social media. Canadian voter turnout is not even near 70%. Further more, users are on their phones for an average of 2hours per day. We typically are not even eating for that long in a day. She justifies that anything that we do this frequently most definitely has an impact on our lives. In addition, she states that social media allows for constant comparison towards someone else’s highlights. Which can have detrimental effects on one’s own well being.

From these two sources, comes two opposite results. With my own experience with social media, my support stands behind Bailey’s. Social media usage is becoming more of an epidemic. With the users becoming younger every year, this subject should not be glazed lightly over. The initial study done was too simplistic, and further research should be conducted to truly evaluate the exact impacts of social media influence on our lives.

Welcome to SCIE 300 Blogging!

Welcome to the SCIE 300 course blog!

Here are few things to note before you start posting. First of all, you should read the blogging resources page under the Create menu. This will help a lot if you’re new to using WordPress; you’ll find video tutorials about writing posts on this blog, adding media to your posts, tagging, and categorizing. You’ll also find a link to the grading rubric for your blog posts.

Next, check out the blogging guidelines. Here you’ll find the answer to the question: “What are we supposed to blog about?” You can also check out one of last term’s blogs for some additional inspiration.

There are a few important things to keep in mind when blogging. Please do not assume that just because something is online, it is OK for you to use it. For example, unless it is explicitly stated, an image on the internet can not just be copied, saved, and used in your own post without permission to do so. We’ve provided you with a lot more detail about properly using online content, but if you have questions, let us know.

This blog also contains a lot of resources for you. For example, also under the Create menu, there is a list of suggested software to use for your projects. We’ve also collected some writing and presentation resources. Basic audio/visual equipment can be borrowed from SCIE300. Contact the course coordinator for more info.

Under the Explore menu, you’ll find some sample podcasts and videos, links that may be of interest or assistance, a list of groups and associations related to communicating science, as well as a list of local museums and science centres. The Explore menu also contains a library resources page, which you should definitely have a look at. Finally, there is a bookshelf that lists relevant books that are on reserve for you in Woodward Library.

Let us know if you have any questions about the blog or would like to see any other resources made available. Or, if you find something that you think would be useful to the rest of the class, tell us, and we can add it to the resources. Better yet — write a post about it!

Happy blogging!
