USask researchers develop safer dialysis membrane – SaskToday.ca

SASKATOON — USask researchers have developed a better membrane for dialysis machines that could lead to safer treatment, improved quality of life for patients with kidney failure.
Over two million people worldwide depend on dialysis or a kidney transplant, according to the National Kidney Foundation. Globally, the number of individuals facing kidney failure has climbed 35 per cent since 2009 and nearly half (46 per cent) of the new patients are under age 65.
Using the Canadian Light Source (CLS) at the University of Saskatchewan (USask), researchers have developed a better membrane for dialysis machines that could lead to safer treatment and improved quality of life for patients with kidney failure.
A dialysis machine is used to filter toxins, waste products, salts, and excess fluid from a patient’s blood when their kidneys can no longer perform this function well. However, negative reactions between dialysis membranes and the patient’s blood can lead to serious complications like blood clots, heart conditions, anemia, blood poisoning, infections, and more.
Dr. Amira Abdelrasoul, an associate professor with USask’s College of Engineering, is an expert on membranes and is determined to help patients on dialysis. “I lost a close family member due to dialysis,” she said. “I saw all the complications he experienced and how he suffered. So, I put all my efforts, knowledge, and background into this research area because I would like to support patients and avoid anyone having to lose a loved one from this treatment.”
The new dialysis membrane developed by her team is a significant improvement over those used in hospitals today, according to Abdelrasoul. Some of the commercial membranes currently in use contain heparin, a medicine that reduces blood clots; however, they also have an intense negative charge on their surface that causes serious side effects.
In a paper recently published in the journal Membranes, Abdelrasoul and her team describe how their new membrane not only maintains a reduction in blood clotting but also has a neutral surface that is biocompatible and should lead to improved outcomes for patients.
“This will lead to less cell destruction and means that we could regulate inflammation to prevent any tissue damage,” she said. “It has a more stable hydration layer that is ten times better than commercial ones. This is the best we have ever achieved.”
The team used the CLS’s BMIT beamline to analyze and develop their membrane.
“Working at CLS was always an amazing experience for me because with advanced-control imaging we could see human serum proteins inside membrane channels during the flow like never before. Other techniques would only show us the top of the membrane and at the end of the filtration process,” she added.
The BMIT beamline enabled the team to monitor – in real time — the flow in each layer of their membrane.
“It helped us to understand why and how proteins accumulate and block membranes under different conditions,” she shared. “I believe that the quantitative and qualitative data that we achieved at CLS will lead to a real change for dialysis patients, and of course it’ll make the University of Saskatchewan and Canada leaders in dialysis membrane technology.”
Her research group recently filed a provisional patent for one of the top-performing membrane materials they developed, and they are continuing to test and develop their membrane to ensure it is safe for a variety of patients. They are hopeful that their membrane could have long-term benefits for patients on dialysis.
“This achievement could lead to a reduction in physical and psychological symptoms that patients experience and improve their quality of life,” said Abdelrasoul.

The Key Role of Trustworthy Babysitters in Balancing Work and Family Life


|
Are you a busy parent in constant pursuit of the elusive work-life balance? We know firsthand how overwhelming and challenging it can be to juggle professional commitments while still having quality time with your children.
That’s why we’re here to discuss an essential ingredient that unlocks the secret to harmony: trustworthy babysitters.
What Characteristics Parents Should Look for When Choosing a Babysitter?
Parents should look for a few key characteristics when choosing a babysitter. A good babysitter should be patient, responsible, and reliable. They should also be comfortable with children and have prior experience caring for them.
Besides, the babysitter must be able to communicate effectively and follow directions well. The babysitter should be someone the parents can trust to care for their children in their absence.
Strategies for Parents to Establish Reasonable Anticipations
As a parent, finding babysitters you can trust to care for your children is vital. However, it is also important to establish reasonable expectations for your babysitters.
Some tips for establishing reasonable expectations for babysitters include:
- Set clear expectations: Sit down with your babysitter to discuss bedtime routines, dietary preferences, and any necessary medications.
- Allow flexibility: While clarity is vital, also provide room for your babysitter to use their judgment and feel comfortable in their role.
- Trust their expertise: Once expectations are set, trust your babysitter’s judgment as a professional caregiver to avoid undermining their authority and creating discomfort in their role.
Determining a Fair Payment Plan
Determine your babysitting budget, factoring in your income and family size, while researching local rates. Account for the babysitter’s experience and qualifications, giving preference to those recommended by trusted sources.
Engage in open negotiations with your chosen babysitter. This aims to find a mutually agreeable arrangement that accommodates both your budget and their needs.
Tips on Finding Trustworthy and Compassionate Caregivers
When seeking a caregiver for your child, to ensure you find the right fit:
- Seek recommendations from trusted sources such as friends, family, and neighbours who may have suggestions for caregivers in your area.
- Conduct online research to review feedback and check references to gauge candidates’ qualifications and experience.
- Request references and contact details from the caregivers’ previous employers or families they have worked with.
- Trust your instincts and ensure you feel at ease with the caregiver, ensuring they are someone you can entrust with your child’s well-being.
Conclusion
Being able to trust your babysitter means you can have peace of mind knowing your child is safe and cared for.
Spending some time researching online reviews or asking friends and family for recommendations will help you find the perfect fit so you can feel more at ease while juggling work commitments in today’s hectic world.

Alberta COVID hospitalizations up 73% since July: health minister
|
Three weeks after the start of the school year, Alberta’s health minister provided an update on the spread of airborne viruses in the province.
Adriana LaGrange also said more information about flu and next-generation COVID-19 vaccines will soon be released.
“Now that we will be spending more time indoors, we need to make doubly sure we are following proper hygiene protocols like handwashing and staying home when sick,” LaGrange said. “It also means respecting those who choose to wear a mask.”
Global News previously reported that influenza vaccines will be available on Oct. 16 with the new Moderna vaccine formulated to target the XBB.1.5 variant likely to be available at around the same time. On Sept. 12, Health Canada approved the use of the Moderna vaccine.
“More information on immunizations against respiratory viruses including influenza and COVID-19 will be available shortly,” the health minister said.
LaGrange said there have been 28 cases of influenza and five lab-confirmed cases of respiratory syncytial virus (RSV) since Aug. 28.
“This is consistent activity for this time of the year,” the health minister said in a statement.
The end of August or the beginning of September has typically marked the beginning of flu season for provincial health authorities.
LaGrange also provided an update on the ongoing COVID-19 pandemic in the province.
From Aug. 28 to Sept. 8, there were a total 92 new hospitalizations and three ICU admissions, bringing the total to 417 in hospital and seven in ICU, a 73 per cent increase of COVID hospitalizations from the last reported info.
On July 24 – the last update to the province’s COVID data dashboard – there were only 242 in hospital.
“Sadly, five Albertans died during that period due to COVID-19,” LaGrange said.
LaGrange said the reporting dashboard is being refreshed to include RSV, influenza and COVID-19 data, work that was originally expected to be completed on Aug. 30. The latest data on the province’s influenza statistics dashboard is dated July 22.
“This work is currently underway and will be available in the coming weeks,” LaGrange said.
She said data for the dates between July 24 and Aug. 27 will be available when the new dashboard goes online.
Amid more hospitals continent-wide reinstating masking requirements in the face of increased hospitalizations, the health minister made no mention of any such moves for Alberta hospitals. Acute care COVID-19 outbreaks in Alberta jumped from Sept. 5 to 12, with 146 per cent more healthcare workers and 55 per cent more patients testing positive for COVID.
LaGrange stressed the “collective responsibility” to prevent the spread of airborne viruses like COVID and influenza.
“As a mother and grandmother, I understand the anxiety that comes with sending your children back to school. I want to reassure you that Alberta’s government has the health and well-being of all young Albertans top of mind,” the health minister said.
