果冻影院 and the University of Toronto team up to understand chronic pain in children
Doctors at the two partner institutions have joined forces to investigate an under-studied area of research
13 March 2019
*Update 04/03/2020: Dr Moayedi received a $100,000 grant聽from the Canadian Institutes of Health Research, on聽which he is principal investigator and Dr Walker is a collaborator. In addition,聽Dr Moayedi is a co-investigator and Dr Walker is a consultant on a聽$9 million multisite NIH HEAL Grant in pediatric musculoskeletal pain. Other outputs from their research include publication in and posters at the 7th International Congress on聽Neuropathic Pain (May 2019) and IASP World Congress on Pain (2020).
果冻影院 has teamed up with the University of Toronto to investigate chronic pain in children, in a bid to contribute to what academics at the partner institutions say is an under-studied area of research. 聽
Dr Suellen Walker (果冻影院 Great Ormond Street Institute for Child Health) has partnered with Dr Massieh Moayedi (University of Toronto鈥檚 Hospital for SickKids) with support from the 果冻影院-University of Toronto Strategic Partner Funds, to investigate the mechanisms of paediatric chronic pain, which affects a reported 15-20% of children and young people worldwide.
Major world centres
There is a need for research into chronic pain in children as the impact of pain and the types of medical conditions associated with it can differ from adults. 果冻影院 and the University of Toronto are uniquely placed to carry out this research. Great Ormond Street Hospital is one of the largest paediatric hospitals in the UK, while SickKids is the largest paediatric hospital in Canada, and both have a strong commitment to research and close links with related academic institutions.
鈥淭here are relatively few research hospitals in the world focusing on pain in children,鈥� said 果冻影院鈥檚 Dr Walker. 鈥淪o to bring two of the world鈥檚 major centres together is a huge benefit as we have access to clinical populations that are quite unique.鈥�
Dr Moayedi added, 鈥淲hile there has been increasing research that includes neuroimaging to understand chronic pain in adults, there has been much less research in the use of imaging to improve understanding of mechanisms of chronic pain in children. There are about five studies, and these do not encompass a broad range of causes of chronic pain. We tried to do a meta-analysis to inform our study, but at this stage, there just isn鈥檛 the data.鈥�
Complementary specialities
Another advantage of the collaboration is that it pools the researchers鈥� respective areas of expertise in child health. Dr Walker鈥檚 果冻影院 team focuses on neuropathic pain, while Dr Moayedi and the Toronto team focus on non-inflammatory musculoskeletal pain. Part of their collaborative research focus will be on assessing the differences and commonalities between different types of chronic pain.
聽鈥淚 have a clinical background but have had a joint clinical academic role for many years. In our Chronic Pain Clinics, children are seen by a multidisciplinary team that includes a pain clinician, psychologist, physiotherapist, nurse specialist and other health care providers as needed. Our research similarly brings together investigators with different expertise and techniques to more fully assess the pain and its impact.
鈥淢assieh鈥檚 experience with MR imaging and pain matches well with our co-investigator Chris Clark, who is Professor of Imaging and Biophysics at 果冻影院 GOS Institute of Child Health, and has extensive experience using MRI to evaluate changes in the brain throughout development and related to disease in children,鈥� said Dr Walker.
Dr Madeleine Verriotis, Senior Research Associate at 果冻影院 GOS Institute of Child Health, spent a week in Toronto and said: 鈥淚鈥檝e used various techniques previously, including scalp electroencephalography and functional near-infrared spectroscopy, but I鈥檝e not used MR imaging before so I have been learning from Chris鈥� team. In addition to this, looking at different analysis methods with Massieh has been extremely helpful for us to proceed with analysis here.鈥�
Similarly, Dr Moayedi and the team from SickKids are benefitting from Dr Walker鈥檚 expertise in Quantitative Sensory Testing (QST) in a paediatric population.
Early intervention
Explaining the motivation behind their collaboration, the team point out that early intervention is vital. According to Dr Moayedi, 鈥淚f these kids can鈥檛 go to school and participate in usual activities, it can affect their mood, which makes their pain worse, and it becomes a vicious circle.
鈥淪o the whole point is to break this cycle 鈥� where we can intervene, and both improve function in childhood, but also reduce the risk of pain persisting into adulthood. The brain can adapt but the longer pain persists, the harder it can be to reverse that effect.鈥�
Dr Walker agrees. 鈥淭hat鈥檚 been the huge advantage of the collaboration 鈥� being able to apply this specifically to child health. Childhood and adolescence are important times for the maturation of the brain鈥檚 connectivity and function.鈥�
Shifting the culture
The researchers are hoping that their joint work will both propel the science and change the thinking around paediatric pain. 鈥淥ne of the problems with chronic pain is that pain is, by definition, subjective; but imaging and QST and the additional measures that we鈥檙e using (assessing quality of life, mood, etc.) can help us to more clearly identify changes in pain processing and its impact.
鈥淎dult chronic pain has been poorly understood, but since the 1980s and 1990s that culture has started to shift 鈥� imaging studies have been important for demonstrating associated changes in the structure and/or connectivity of regions in the brain,鈥� said Dr Moayedi. 聽
Initially, the researchers were concerned that it would be difficult to find enough children to take part in the research, but they have found children to be keen participants.
Dr Moayedi, who has worked also on pain studies in adults, notes: 鈥淜ids are often a lot more willing than adults are.鈥� The teams at 果冻影院 and Toronto also recognise the need for further education regarding pain for patients and families, as well as for health professionals.
Continuing collaboration
A year on from receiving their 果冻影院-University of Toronto matched funding, the collaboration is going from strength to strength. Joint meetings have allowed the two institutions to share protocols and match their approaches before combining the data 鈥� but they say there is more work to be done.
鈥淚鈥檓 applying for a Canadian Institute of Health Research grant,* which focuses on musculoskeletal pain but brings in Suellen as a Co-Principal Investigator,鈥� said Dr Moayedi. 鈥淭his 果冻影院-UofT fund was a catalyst for us, because it was an opportunity to loop in the pain community at 果冻影院. Had the fund not been there this collaboration wouldn鈥檛 have happened.鈥�
鈥淚t also meant that when an opportunity came up for a joint PhD, we already had a collaboration that would fit with that. Massieh is co-supervisor with Madeleine and Chris Clark for our PhD student who will go to Toronto for six months,鈥� said Dr Walker.
