Simple CT scanning procedure can predict effectiveness of ovarian cancer treatment
Technology developed at Western University and Lawson Health Research Institute can provide a new window into whether or not patients are responding to treatment for advanced ovarian cancer. A multi-centre clinical trial has demonstrated that CT Perfusion, which measures blood flow and blood volume to tumours associated with ovarian cancer, can provide an accurate prediction of how well a treatment is working, allowing physicians the opportunity to better plan treatment. Funding for the trial was provided by the US National Cancer Institute through the National Clinical Trials Network including NRG Oncology and ECOG-ACRIN.
“CT perfusion is homing into the change in blood flow to the tumour before and after treatment,” said Ting-Yim Lee, professor at Western University’s Schulich School of Medicine & Dentistry, scientist at Lawson Health Research Institute, and a Medical Physicist at St. Joseph’s Health Care London. “In this particular case we can see that blood flow tends to decrease in those who will survive longer without symptoms, whereas for those whose symptoms will recur within six months, we saw blood flow to the tumour increase after their treatment.”
The study was published in the journal, Clinical Cancer Research. Its authors point out that in 60 to 85 per cent of ovarian cancer patients, relapse will occur after initial treatment. By using CT perfusion to identify which patients are more likely to benefit from a specific therapy enables better patient selection and treatment planning, and also provides a biomarker for future clinical trials assessing new treatment options. The authors also point out that although the trial is promising, further studies are required to corroborate the current findings.
“Using this method we are able to see a change in the blood flow as early as four weeks after treatment. This means we don’t have to wait months to determine whether symptoms will recur, we are able to tell whether the treatment is effective much sooner,” said Lee.
Developed by Lee and his team at Western University’s Robarts Research Institute, CT perfusion uses X-ray dye in combination with existing CT scanners to measure blood flow. The technology is already used globally to assess blood flow to the brain after stroke. This clinical trial for use in ovarian cancer took place across 19 U.S. centres, and also demonstrated that the technology is easily implemented onto any existing CT scanner, and requires minimal training to be successful.
Simple device improves care after kidney transplantation
LONDON, ON – In a published study, a team from Lawson Health Research Institute has found that a simple device can reduce swelling after kidney transplantation. The geko™ device, manufactured by Sky Medical Technology Ltd and distributed in Canada by Trudell Healthcare Solutions Inc., is a muscle pump activator which significantly improves blood flow by stimulating the body’s ‘muscle pumps.’ Patients using the device following kidney transplantation experienced shorter hospital stays and reduced surgical site infections by nearly 60 per cent.
Kidney and simultaneous pancreas-kidney transplantations can significantly reduce mortality and improve the quality of life for patients with end stage renal disease. “After surgery, many of these organ recipients require a longer hospital stay due to delayed kidney function, infection, lack of mobility or edema,” says Dr. Alp Sener, Lawson Scientist and Transplant Surgeon in the Multi-Organ Transplant Program at London Health Sciences Centre (LHSC).
Edema is swelling caused by excess fluid trapped in the body’s tissues which can impact wound healing. The current standard of care for managing lower-limb edema and improving blood flow is thrombo-embolic-deterrent (“TED”) stockings used with compression devices. Sleeves pumped with air squeeze the lower legs to boost circulation. They can be uncomfortable to wear, and the large pump can inhibit early mobility and disrupt sleep after surgery.
In a randomized controlled clinical trial spanning two years, 221 transplant recipients at LHSC either wore the standard TED stocking and pump or the geko™ device for six days after surgery. Dr. Sener’s research team found that wearing the device increased urine output by 27 per cent and lowered weight gain by over a kilogram. With more urine produced and less fluid retention, patients experienced 31 per cent less swelling. The duration of costly hospitalization was shortened by over one day after kidney transplantation compared to the standard of care.
A 60 per cent reduction in wound infection rates was a striking observation. “Transplant patients are at a higher risk of infection due to the immunosuppressant medications needed after surgery,” explains Dr. Sener, who is also the President of the Urologic Society for Transplantation and Renal Surgery, a global organization affiliated with the American Urological Association. “Reducing infection means a much better outcome for the patient and considering that recent data shows wound infections can cost the health care system thousands of dollars per person, it’s a win-win situation.”
Some of the study participants wore pedometers to track their steps, and those using the geko™ device had improved mobility after surgery. The team suspects this may be due to reduced swelling which could improve ease and comfort when moving.
“The study results have been both surprising and exciting. Not only have we cut down wound infection rates but we have also seen a considerable improvement in the new organ’s function following transplantation. Patients report feeling more satisfied with the transplant process and are more mobile,” says Dr. Sener. The geko™ device is now being offered to patients at LHSC in recovery after receiving a new kidney.
Ruben Garcia, 68 years old, recently received a new kidney from his daughter, Ruby, who was a match as a living kidney donor. Following his surgery, Garcia found it difficult to get out of bed due to the pain and swelling, and the function of his new kidney was very low. “My surgeon explained in very simple terms that it was as if my new kidney wasn’t awake yet,” describes Garcia.
Dr. Sener recommended that Garcia use the geko™ device to help stimulate blood flow in a way that is similar to walking. Garcia was soon able to sit up on a chair and by the next day he was walking. “My kidney woke up and starting working again! I could feel the device working and it was comfortable to wear, almost like a massage for my legs. I’m very grateful for the care that I received.”
Dr. Sener adds that “using a muscle pump activator could be a game changer for other procedures like orthopedic implants where wound infection can have disastrous consequences or in surgeries where wound infections are more common such as in cancer and intestinal surgery.”
The geko™ device is non-invasive, self-adhering, battery-powered and recyclable. It generates neuromuscular electro-stimulation and unparalleled systemic blood flow that equates to 60 per cent of that achieved by walking. Pain-free muscle contraction compresses deep veins in the lower legs to create better blood flow in these vessels and return blood to the heart. It is particularly well suited to hospital settings as it portable and requires minimal training. For the indications for the use of the geko™ device, go to www.gekodevices.com.
“The results of the study provide further evidence that the geko™ device is an effective treatment option that can improve outcomes for patients and help them return home sooner, while reducing costs for the health-care system,” says George Baran, Executive Chairman of the Trudell Medical Group and a Director of Sky Medical.

Small box holds big promise in cardiac care
London, Ontario – For a non-descript box it wields a mighty name and even more impressive possibilities for people with heart disease. Called the AngioDefender, the machine – no bigger than a shoebox - holds much promise in the ability to personalize cardiac care, say researchers at Lawson Health Research Institute, the research arm of St. Joseph’s Health Care London.
St. Joseph’s Hospital in London is the only Canadian cardiac rehabilitation centre testing the AngioDefender, a non-invasive tool that can assess the health of blood vessels by using a simple blood pressure cuff. At the recent Canadian Cardiovascular Congress in Toronto, Lawson researchers presented findings of their study, which assessed the feasibility and reliability of the AngioDefender in patients undergoing cardiac rehabilitation.
“Right now everyone basically gets similar treatment in terms of maximizing therapy based on risk factor profiles,” says Dr. Neville Suskin, Lawson scientist and medical director of St. Joseph’s Cardiac Rehabilitation and Secondary Prevention Program. “With this machine, if it does what we hope it will do, it gives us insight into a person’s vascular health so that we can know if the treatment is working and adjust and individualize their care.”
Also key, says Dr. Suskin, is the machine can be used by any medical professional in any doctor’s office.
The AngioDefender system, manufactured by Everist Health, measures the health of the endothelium — the interior lining of blood vessels. Using a blood pressure cuff, the device runs through a series of inflations and deflations to analyze the endothelium’s response to changes in blood flow. When the blood pressure cuff is inflated, blood flow decreases and stops. When the blood pressure cuff deflates, blood flow increases and the main artery in the arm responds by getting bigger (dilating). How well it dilates is a sign of endothelial (vascular) health.
Using a specially designed data analysis algorithm, the AngioDefender system produces each patient’s “flow-mediated dilation” score. When the information is combined with the patient’s other risk factors, it calculates the patient’s vascular age. The whole process takes 15 to 20 minutes.
“The ability for a health professional to obtain a measure of vascular health in such a straightforward manner is very novel” says Dr. Suskin, whose team has found that the machine is feasible to use in a busy cardiac rehabilitation practice setting. “It doesn’t take long, patients tolerate it, and they are also very keen to know their vascular health as determined by this machine.”
If successful, the device may become part of the standard screening to assess early-stage cardiovascular disease and atherosclerosis, and an innovative way to monitor the effectiveness of treatment.

Smart Homes for community living
A first-of-its-kind research study by Lawson Health Research Institute is moving into the community and evaluating the use of smart technologies in the home for people with severe mental illness.
After prototyping this approach within a hospital setting through St. Joseph’s Health Care London, the research team will be outfitting eight affordable housing units at Canadian Mental Health Association Middlesex and London and Middlesex Community Housing with smart home technology.
In-hospital prototype for using smart technologies in the home
The Smart Home Community Model
“This solution is for people who are having difficulty managing their everyday life and need a high level of care to maintain community living,” says Dr. Cheryl Forchuk, Assistant Scientific Director at Lawson and project lead for the Smart Home Community Model. “Technology and applications are being embedded in the lived environment and then tested to ensure they are safe, secure and appropriate for use in health care.”
Dr. Cheryl Forchuk announcing this phase of the project, from within one of the apartment buildings.
Study participants will select from a wide range of tools that will best meet their individual needs. Devices such as smartphones and touch-screen monitors connect with applications to provide video-conferencing, questionnaires, and prompts and reminders based on the person’s care plan.
As an example, participants have regular access to mood scales with questions about how they are feeling. These are used extensively in mental health care settings to help address issues and start conversations with clients. The care team receives notification of the answers, giving regular insight into how the person is doing and if they need additional follow-up.
Depending on their needs, participants have access to automated medication dispensers and smart health monitoring devices, such as weigh scales, blood pressure monitors, glucometers, and tracking monitors for heart rate, activity and sleep.
This patient population often faces health challenges on multiple fronts, with higher rates of diabetes and cardiac issues. They can struggle keeping balance when it comes to activity, weight and sleep. Fluctuations in any of these can be early indicators that a crisis is looming.
“By integrating and testing these smart tools for health care, we are not simply looking at the technology but how it can be used as a tool for communication,” says Dr. Forchuk. “We see smart technology supporting more seamless communication between health care providers and the client – all from their own homes. This helps them better manage their care and overall wellbeing, flag issues earlier on and avoid trips to the clinic when appropriate.”
Paula's Perspective
Paula Rawlinson is chair of the family council and sits on the patient council for St. Joseph’s Parkwood Institute Mental Health Care. She personally has lived experience with mental health and as also acted as a caregiver for a family member.
“Both myself and my family member could have benefitted from these tools, very much so,” says Paula. “When I was really suffering, I isolated myself from people a lot. Even when I lived in a group home because I needed a higher level of care. Having some sort of helpful device right there, encouraging me to keep up with things and connecting me to someone I trusted, would have made a huge difference. Especially after the first discharge.”
She adds that for someone who is really struggling, this could be a life-saving strategy that makes a vital difference.
For her family member, Paula sees many uses for these tools and knows that they would actually use them. “I’ve been able to see the tools and they are even simpler than using email. It makes them accessible to a lot of people in the community who would make good use of them to improve their situation.”
Results and Impact
Some of the tools as part of this project have previously been tested formally as part of a research study and shown positive results.
The health team has access to the data to more easily stay in touch with the person. They can work together to track trends and pinpoint triggers, creating more personalized and effective strategies. With less focus on the daily aspects of care, providers reported that in-person meetings offered more meaningful and important discussions.
“All of the data is also viewable by the client who continues to work with a health care provider,” explains Dr. Forchuk. Clients can reach out sooner and get support more quickly. Potential issues and crisis are addressed earlier on, and in previous studies they reduced psychiatric readmissions, emergency room visits and arrests. Clients reported more satisfaction with their care and feeling better overall.
“When we have more people successfully achieving community living and managing their care with fewer outpatient visits and other service utilization, we can open up capacity in the system and deliver quality care at a lower cost.”
The team anticipates that participants will experience greater levels of independence and autonomy in maintaining housing and self-care for mental health and chronic illnesses.
Paul points out that one of the key outcomes is to avoid re-admission. “One of the main, recurring struggles is loneliness. With tools to keep people in more regular contact with their care team and assistance with their everyday life, they can shift more to having a fun life. You can build up those crucial relationships with family and friends – and those people feel less burnout as caregivers. It adds a lot of support and resiliency.”
Dr. Forchuk adds that “our approach is to care for the whole person – mind, body and soul. It goes beyond managing the mental illness and is about supporting people in managing their life.”
The team already has four people enrolled in the study. In addition to people living alone, they will have participants with roommates and families to test the strategy under various real-life situations. The initial study will take place over one year.
This phase of project has received generous funding from the Canada Mortgage and Housing Corporation. The Canadian Institutes for Health Research contributed to the initial pilot phase.
Smart technology in the home effective for supporting mental health care, study finds
A research team from Lawson Health Research Institute has announced promising results from a one-of-a-kind demonstration study that evaluated the use of smart technologies in the home for people with severe mental illness.
“Our Smart Homes solution is for people who are having difficulty managing their everyday life and need a high level of care to maintain community living,” says Dr. Cheryl Forchuk, Assistant Scientific Director at Lawson and project lead for Smart Home Community Model Phase.
“We have strong initial evidence showing that technology and applications embedded in the lived environment are safe, secure and appropriate for use in health care.”
After prototyping this approach within a hospital setting through St. Joseph’s Health Care London, the research team outfitted affordable housing units at Canadian Mental Health Association (CMHA) Elgin-Middlesex and London and Middlesex Community Housing (LMCH) with smart home technology.
The team presented the full study results during a virtual event.
There were 13 participants as part of this project phase who had different living situations such as individual apartments, group homes or family homes. Anxiety, mood and psychotic disorders were the most common mental health diagnoses, with many also suffering from chronic pain that make the activities of daily life difficult.
Each study participant selected from a wide range of tools that would best meet their individual needs, with all but one participant selecting more than one tool. Devices such as smartphones and touch-screen monitors connect with applications to provide video-conferencing, questionnaires, and prompts and reminders based on the person’s care plan. They also had access to automated medication dispensers and smart health monitoring devices for tracking heart rate, activity and sleep.
“All of the data is viewable by both the client and health care provider, allowing for more seamless care and identification of issues earlier on,” adds Dr. Forchuk.
The study found that visits to a health or social service provider and the emergency department decreased, as did home visits from a provider. Telephone appointments increased and communication between the client and provider were enhanced. Almost 80 per cent of the participants felt that the technologies improved their health care overall.
Higher levels of community integration and a greater sense of independence were also reported, including a better ability to remain connected with friends and family during the pandemic. When medication dispensers were used, no medication doses were missed. Participants felt they were better able to track their own health and more motivated to lead healthier lives.
“The compliment of smart technology in our Supportive Independent Living Program has proven to improve the quality of life of participants by reducing use of emergency services and fostering learning opportunities for independent living skills to create a good quality of life,” says Nedrita Shemshedini, Manager of Supportive Independent Living at CMHA Elgin-Middlesex. “In a large-scale rollout, this model could improve wellbeing and empower persons to better manage their care.”
The research team hopes this work will help inform the integration of smart technology more fully into mental health care delivery. Laura Pearson, Executive Director at Ontario Peer Development Initiative, urges that “there is a need for key policies to be addressed and changed in order to support funding and access for technology at a system level for the purpose of mental health care.”
The community model phase of the Smart Homes project was generously funded by the Canada Mortgage and Housing Corporation (CMHC).

“More and more, smart technologies like phone applications or virtual care are being used for mental health care. A smart home solution like the one we have tested could be considered a higher dose of technology, offered to clients with higher needs. The right dose for one may not work for another – the technological solutions used should vary depending on the individual,” explains Dr. Forchuk.
