Hamilton Health Sciences (HHS) hematologist Dr. Tobias Berg is passionate about translational research, where discoveries in the lab lead to treatments that prolong and save lives. Berg leads a research team dedicated to improving outcomes for people diagnosed with acute myeloid leukemia (AML), a rare type of cancer that starts in the blood-forming cells of the bone marrow.

“We’re very open to collaborating locally, provincially, nationally and internationally.” — Dr. Tobias Berg.

Vital supporters of this leading-edge research include hundreds of HHS blood cancer patients, including many with AML and multiple myeloma, who volunteer to provide cell samples to the HHS McMaster Cancer Research Stem Cell Bank.

AML samples from patients are stored in a special freezer at very low temperatures (-150 °C).

Samples are taken during medical procedures related to their care, such as blood being drawn or bone marrow biopsies.

“Patients undergoing certain procedures as part of their care plan may be asked if they would be willing to have a small part of their sample go towards research,” says Berg. “So no additional procedure is needed in order to collect samples.”

The cell bank currently collects approximately 100 samples per year, from over 50 patients per year. Most patients are keen to donate. “In fact, I’ve rarely experienced anyone saying no,” says Berg. “It’s very important to these patients that they have opportunities to contribute to advancements through research that could prolong future patients’ lives.”

“Dr. Berg is an outstanding researcher and a caring physician whose leadership is improving outcomes for cancer patients.” — Dr. Marc Jeschke, HHS vice president of research and chief scientific officer.

Berg spends half his work week leading research into AML at the Berg Research Lab at the Centre for Discovery in Cancer Research at McMaster University, where he is senior scientist and leads the translational oncology program. This program acts as a bridge between basic scientists and clinicians working to improve the lives of patients affected by cancer. He’s also a scientist with the Escarpment Cancer Research Institute (ECRI), a joint institute of HHS and McMaster University. Based at HHS Juravinski Hospital and Cancer Centre, ECRI’s work focuses on research that has an impact on patient outcomes.

The other half of Berg’s time is spent caring for patients as a hematologist at HHS Juravinski Hospital and Cancer Centre.

Berg started expanding the existing cell bank after arriving in Hamilton from Germany in 2019, as the inaugural Boris Family Chair in Leukemia and Hematopoietic Stem Cell Translational Research at McMaster.

“Dr. Berg is an outstanding researcher and a caring physician whose leadership is improving outcomes for cancer patients,” says Dr. Marc Jeschke, vice president of research and chief scientific officer for HHS. “Dr. Berg has also been instrumental supporting leading-edge research through his commitment to expanding the cell bank.”

Many diseases in one cancer

While AML is a rare cancer, it’s the most common type of acute leukemia in adults. The most effective treatment, which offers a potential cure, is an allogeneic stem cell transplant where the patient receives stem cells from a donor. Even with a transplant, relapse is unfortunately common. Due to certain pre-existing conditions, not all AML patients qualify for a transplant which leads to a less than 30 per cent chance of long-term survival with this disease.

That’s why research into prolonging patients’ lives is so vital.

Improving outcomes

While AML is considered one type of cancer, it’s actually many different diseases because patients have fairly unique combinations of mutations that occur and drive the disease.

“So it’s important to understand, through research, the biology of these subgroups and mutations in order discover the most appropriate treatment for every individual patient,” says Berg, who analyses the metabolism of diseased cells and how they interact with the immune system in order to understand why relapse is so common and find more effective treatments for managing care after a transplant to prevent a reoccurrence.

One starting point is how to deal with minimal residual disease, which refers to a small number of cancer cells often left in the body after cancer treatment, such as a stem cell transplant. Researchers try and determine why these cells can survive treatment, and why they may even continue to grow and mutate after treatment, causing a relapse.

“In order to better treat minimal residual disease, we need to understand how leukemia cells become resistant to treatment,” says Berg.

Where do leukemia cells get their energy?

“We do this by analyzing the metabolism of diseased cells and how they interact with the immune system,” he says. “We look at where leukemia cells derive their energy from and see how our treatments change this process. Since relapse after a transplant often happens when diseased cells become invisible for the immune system, we also try to understand how they get recognized by the immune system. As the donor’s immune system is a key part of the transplant, we study how we can improve the way the immune system can recognize the leukemia cells.”

Berg and his team are initiating a novel approach to understand how genes are regulated on a single-cell level. “We are doing these single cell studies with a new technology we got running with funding from the Marta and Owen Boris Foundation,” says Berg, adding he’s grateful for ongoing support from the foundation, without which none of this research would be possible, as well as funding from other organizations including the Ontario Institute for Cancer Research and the Hamilton Health Sciences Foundation.

Berg recently also received funding from the Leukemia and Lymphoma Society of Canada to explore how healthy cells surrounding cancerous ones contribute to resistance of the diseased cells, and which treatments this could be blocked with. “We are particularly interested in changes in the cancerous cells’ energy production that occur due to this interaction with surrounding cells,” says Berg.

Opportunities for collaboration

While Berg’s team focuses on AML, they are far from siloed in their research. “Working at the Centre for Discovery in Cancer Research allows for collaboration with other researchers focused on other types of cancer and allows us to work together with outstanding researchers in the fields of immunology, stem cell biology and metabolism,” says Berg.

“We share our experiences, research technologies, and collaborate on ways to improve outcomes for patients with a variety of cancers. Our work recently, for example, helped to better understand the effect of a novel experimental approach in prostate and lung cancer. We’re very open to collaborating locally, provincially, nationally and internationally.”

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.”
