(JMIR Publications, 2023-01-19) Alvarez, Sergio Diez; Fellas, Antoni; Santos, Derek; Sculley, Dean; Wynne, Katie; Acharya, Shamasunder; Xavier Girones; Girones, Xavier; Coda, Andrea
Background: Type 2 diabetes has a growing prevalence and confers significant cost burden to the health care system. Raising the urgent need for cost effective and easily accessible solutions. The management of type 2 diabetes requires significant commitment from the patient, caregivers and the treating team to optimise clinical outcomes and prevent complications. Technology and its implications for the management of type 2 diabetes is a nascent area of research. The impact of some of the more recent technological innovations in this space such as continuous glucose monitoring, flash glucose monitoring, web-based applications and smart phone and smart watch based interactive applications have received limited attention in the research literature. Objective: This scoping review aims to explore the literature available in type 2 diabetes, flash glucose monitoring and digital health technology to improve diabetic clinical outcomes and thus inform future research in this area. Methods: A scoping review was undertaken by searching Ovid MEDLINE and CINAHL databases. A second search using all identified keywords and index terms was performed on Ovid MEDLINE (January 1966 to July 2021), EMBASE (January 1980 to July 2021), Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, latest issue), CINAHL (from 1982), IEEE XPlore and ACM Digital Libraries, and Web of Science databases. Results: There were very few studies that have explored the use of mobile health and Flash glucose monitoring in type 2 diabetes. These studies have explored somewhat disparate and limited areas of research, and there is a distinct lack of methodological rigor in this area of research. The 3 studies that met the inclusion criteria have addressed aspects of the proposed research question. Conclusions: This scoping review has highlighted the lack of research in this area, raising the opportunity for further research in this area, focusing on the clinical impact and feasibility of the use of multiple technologies including flash glucose monitoring in the management of patients with type 2 diabetes.
Effect of customised preformed foot orthoses on gait parameters in children with juvenile idiopathic arthritis: A multicentre randomised clinical trial
(Elsevier, 2022-04-22) Fellas, Antoni; Singh-Grewal, Davinder; Chaitow, Jeffrey; Santos, Derek; Clapham, Matthew; Coda, Andrea
Background Children with juvenile idiopathic arthritis (JIA) can experience significant physical impairment of the lower extremity. Prolonged joint disease and symptoms may cause gait alterations such as reduced walking speed and increased plantar pressures in diseased areas of their feet. There is limited robust clinical trials investigating the effect of non-invasive mechanical therapies such as foot orthoses (FOs) on improving gait parameters in children with JIA.
Effect of preformed foot orthoses in reducing pain in children with juvenile idiopathic arthritis: A multicentre randomised clinical trial
(Oxford University Press, 2021-10-14) Fellas, Antoni; Singh-Grewal, Davinder; Chaitow, Jeffrey; Santos, Derek; Clapham, Matthew; Coda, Andrea
Objectives The aim of this study is to investigate the effect of customised preformed foot orthoses on pain, quality of life, swollen and tender lower joints and foot and ankle disability in children with juvenile idiopathic arthritis (JIA). Methods Parallel group design. Children diagnosed with JIA were recruited from the three children’s hospital in NSW, Australia. Participants were randomly assigned to a control group receiving a standard flat innersole (sham) with no corrective modifications. The trial group were prescribed a preformed device that was customised based on biomechanical assessments. Pain was the primary outcome and was followed up to 12-months post intervention. Secondary outcomes include quality of life, foot and ankle disability and swollen and tender joints. A linear mixed model was used to assess the impact of the intervention at each time point. Results 66 participants were recruited. Child reported pain was reduced statistically and clinically significant at 4-weeks and 3 months post intervention in favour of the trial group. Statistically significance was not reached at 6 and 12-month follow-ups. Quality of life and foot and ankle disability were not statistically significant at any follow-up; however, tender midfoot and ankle joints were significantly reduced 6-months post intervention. Conclusion Results of this clinical trial indicate customised preformed foot orthoses can be effective in reducing pain and tender joints in children with JIA exhibiting foot and ankle symptoms. Long-term efficacy of foot orthoses remains unclear. Overall, the trial intervention was safe, inexpensive and well tolerated by paediatric patients.

Effectiveness of eHealth and mHealth interventions supporting children and young people living with juvenile idiopathic arthritis: Systematic review and meta-analysis
(2022-02-02) Butler, Sonia; Sculley, Dean; Santos, Derek; Fellas, Antoni; Gironès, Xavier; Singh-Grewal, Davinder; Coda, Andrea
Juvenile idiopathic arthritis (JIA) management aims to promote remission through timely, individualized, well-coordinated interdisciplinary care using a range of pharmacological, physical, psychological, and educational interventions. However, achieving this goal is workforce-intensive. Harnessing the burgeoning eHealth and mobile health (mHealth) interventions could be a resource-efficient way of supplementing JIA management. This systematic review aims to identify the eHealth and mHealth interventions that have been proven to be effective in supporting health outcomes for children and young people (aged 1-18 years) living with JIA. We systematically searched 15 databases (2018-2021). Studies were eligible if they considered children and young people (aged 1-18 years) diagnosed with JIA, an eHealth or mHealth intervention, any comparator, and health outcomes related to the used interventions. Independently, 2 reviewers screened the studies for inclusion and appraised the study quality using the Downs and Black (modified) checklist. Study outcomes were summarized using a narrative, descriptive method and, where possible, combined for a meta-analysis using a random-effects model. Of the 301 studies identified in the search strategy, 15 (5%) fair-to-good-quality studies met the inclusion criteria, which identified 10 interventions for JIA (age 4-18.6 years). Of these 10 interventions, 5 (50%) supported symptom monitoring by capturing real-time data using health applications, electronic diaries, or web-based portals to monitor pain or health-related quality of life (HRQoL). Within individual studies, a preference was demonstrated for real-time pain monitoring over recall pain assessments because of a peak-end effect, improved time efficiency (P=.002), and meeting children's and young people's HRQoL needs (P<.001) during pediatric rheumatology consultations. Furthermore, 20% (2/10) of interventions supported physical activity promotion using a web-based program or a wearable activity tracker. The web-based program exhibited a moderate effect, which increased endurance time, physical activity levels, and moderate to vigorous physical activity (standardized mean difference [SMD] 0.60, SD 0.02-1.18; I =79%; P=.04). The final 30% (3/10) of interventions supported self-management development through web-based programs, or apps, facilitating a small effect, reducing pain intensity (SMD -0.14, 95% CI -0.43 to 0.15; I =53%; P=.33), and increasing disease knowledge and self-efficacy (SMD 0.30, 95% CI 0.03-0.56; I =74%; P=.03). These results were not statistically significant. No effect was seen regarding pain interference, HRQoL, anxiety, depression, pain coping, disease activity, functional ability, or treatment adherence. Evidence that supports the inclusion of eHealth and mHealth interventions in JIA management is increasing. However, this evidence needs to be considered cautiously because of the small sample size, wide CIs, and moderate to high statistical heterogeneity. More rigorous research is needed on the longitudinal effects of real-time monitoring, web-based pediatric rheumatologist-children and young people interactions, the comparison among different self-management programs, and the use of wearable technologies as an objective measurement for monitoring physical activity before any recommendations that inform current practice can be given.
Effectiveness of preformed foot orthoses in reducing lower limb pain, swollen and tender joints and in improving quality of life and gait parameters in children with juvenile idiopathic arthritis: a randomised controlled trial (Protocol)
(BMJ Publishing Group Ltd, 2017-11-30) Fellas, Antoni; Singh-Grewal, Davinder; Chaitow, Jeffrey; Santos, Derek; Coda, Andrea
Background Many children and adolescents with juvenile idiopathic arthritis experience lower limb problems which may lead to physical disabilities significantly impacting on their quality of life and symptoms. Emerging evidence has identified the effective role of podiatry in the management of juvenile idiopathic arthritis, suggesting the clinical benefit of different orthotic therapies. Methods This study will be a parallel-group designed, multicentre, randomised controlled trial, aiming to recruit 66 children and adolescents with juvenile idiopathic arthritis aged between 5 and 18 years. Those recruited will need to be diagnosed according to the International League of Associations for Rheumatology criteria, and present with lower limb joint pain, swelling and/or tenderness. Participants will be recruited from three outpatient hospital clinics in New South Wales, Australia. Participants will be randomly allocated to receive a trial or control intervention. The trial group will be prescribed a customised preformed foot orthoses; instead, the control group will receive a flat 1 mm insole with no corrective modifications. Primary outcome measure recorded will be pain. Secondary outcomes will be quality of life, foot disability, swollen and tender joint count and gait parameters (such as plantar pressures, walking speed, stance and swing time). The allocated foot orthoses will be worn for 12 months, with data collected at baseline, 4 weeks, 3, 6 and 12 months intervals. Group allocation will be concealed and all analyses will be carried out on an intention to treat. Discussion The purpose of this trial is to explore the efficacy of a cost-effective, non-invasive podiatric intervention that will be prescribed at the initial biomechanical consultation. This approach will promote early clinical intervention, which is the gold standard in paediatric rheumatology. Furthermore, this study has the potential to provide new evidence for the effectiveness of a mechanical intervention alone to reduce swollen and tender joints in juvenile idiopathic arthritis.
Emerging tools to capture self-reported acute and chronic pain outcome in children and adolescents: A literature review
(MDPI, 2022-01-25) Turnbull, Alexandra; Sculley, Dean; Santos, Derek; Maarj, Mohammed; Chapple, Lachlan; Gironès, Xavier; Fellas, Antoni; Coda, Andrea; Torres, Antoni; Ni, Yicheng
The advancement of digital health provides strategic and cost-effective opportunities for the progression of health care in children and adolescents. It is important for clinicians to be aware of the potential of emerging pain outcome measures and employ evidence-based tools capable of reliably tracking acute and chronic pain over time. The main emerging pain outcome measures for children and adolescents were examined. Overall, seven main texts and their corresponding digital health technologies were included in this study. The main findings indicated that the use of emerging digital health is able to reduce recall bias and can improve the real time paediatric data capture of acute and chronic symptoms. This literature review highlights new developments in pain management in children and adolescents and emphasizes the need for further research to be conducted on the use of emerging technologies in pain management. This may include larger scale, multicentre studies to further assess validity and reliability of these tools across various demographics. The privacy and security of mHealth data must also be carefully evaluated when choosing health applications that can be introduced into daily clinical settings.
Foot and ankle pathologies in juvenile idiopathic arthritis: A narrative review
(SpringerNature, 2017-09-01) Fellas, Antoni; Hawke, Fiona; Santos, Derek; Coda, Andrea
Introduction: Foot and ankle pathologies are common in juvenile idiopathic arthritis (JIA) and can cause physical disability and reduce quality of life (1). Early detection and evidence-based treatment of these symptomatic pathologies are an important first step in preventing ongoing pain and long-term disabilities in children with JIA.
Physical examination tool for swollen and tender lower limb joints in juvenile idiopathic arthritis: A pilot diagnostic accuracy study
(MDPI, 2022-04-08) Fellas, Antoni; Singh-Grewal, Davinder; Chaitow, Jeffrey; Warner, Denise; Onikul, Ella; Santos, Derek; Clapham, Matthew; Coda, Andrea
Background: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children, with lower limb involvement highly prevalent. Recent evidence has highlighted the lack of specific lower limb physical examination (PE) tools for clinicians assisting the paediatric rheumatology team in identifying lower extremity disease in patients with JIA. Early clinical detection may lead to more prompt and targeted interventions to reduce lower limb problems in children with JIA. The aim of this pilot study is to provide preliminary data on the diagnostic accuracy of a lower limb PE tool in JIA. Methods: Children with JIA requiring magnetic resonance imaging (MRI) on their lower limb joints per their usual care were eligible. Lower limb joint counts were conducted clinically by a podiatrist and paediatric rheumatologist using the proposed twenty joint per side, PE tool. The PE were compared to MRI assessments completed by two independent paediatric radiologists. Data were analysed using agreement (observed, positive and negative) and Cohen’s kappa with 95% CIs. Results: Fifteen participants were recruited into the study in which 600 lower limb joints were clinically examined. Statistical analysis showed excellent inter-rater reliability between podiatrist and paediatric rheumatologist for both joint swelling and tenderness. Results of the intra-rater reliability of the podiatrist using the PE tool indicated excellent percentage agreements (98.5−100%) and substantial kappa coefficients (0.93−1). The inter-rater reliability between radiological assessments contrasted the PE results, showing low agreement and poor reliability. Comparisons between PE and MRI resulted in poor kappa coefficients and low agreement percentages. The most agreeable joint between MRI and PE was the ankle joint, while the worst performing joint was the sub-talar joint. Conclusion: Results indicate potential clinical reliability; however, the validity and diagnostic accuracy of the proposed PE tool remains unclear due to low kappa coefficients and inconsistent agreements between PE and MRI results. Further research will be required before the tool may be used in a clinical setting.
Physical Examination Tools Used to Identify Swollen and Tender Lower Limb Joints in Juvenile Idiopathic Arthritis: A Scoping Review
(Hindawi Publishing Corporation, 2018-05-15) Fellas, Antoni; Singh-Grewal, Davinder; Santos, Derek; Coda, Andrea
Background. Juvenile idiopathic arthritis (JIA) is the most common form of rheumatic disease in childhood and adolescents, affecting between 16 and 150 per 100,000 young persons below the age of 16. The lower limb is commonly affected in JIA, with joint swelling and tenderness often observed as a result of active synovitis. Objective. The objective of this scoping review is to identify the existence of physical examination (PE) tools to identify and record swollen and tender lower limb joints in children with JIA. Methods. Two reviewers individually screened the eligibility of titles and abstracts retrieved from the following online databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL. Studies that proposed and validated a comprehensive lower limb PE tool were included in this scoping review. Results. After removal of duplicates, 1232 citations were retrieved, in which twelve were identified as potentially eligible. No studies met the set criteria for inclusion. Conclusion. Further research is needed in developing and validating specific PE tools for clinicians such as podiatrists and other allied health professionals involved in the management of pathological lower limb joints in children diagnosed with JIA. These lower limb PE tools may be useful in conjunction with existing disease activity scores to optimise screening of the lower extremity and monitoring the efficacy of targeted interventions.
Prevalence, presentation and treatment of lower limb pathologies in juvenile idiopathic arthritis: A narrative review
(Wiley, 2017-08-02) Fellas, Antoni; Hawke, Fiona; Santos, Derek; Coda, Andrea
Juvenile idiopathic arthritis is a chronic, autoimmune, inflammatory joint disease. It is the most common arthritis in children and adolescents. This paper reviews the presentation and treatment of lower limb pathologies in juvenile idiopathic arthritis from an allied health perspective. Common lower limb pathologies include: synovitis causing swelling, tenderness and pain; persistent inflammation leading to flexion contractures; limb length discrepancies; muscle atrophy; enthesopathies such as plantar fasciitis and Achilles tendonitis; and tenosynovitis. Allied health professionals may use a range of non-invasive therapies, including hydrotherapy, strengthening and stretching exercises, massaging, taping and foot orthoses to manage lower limb pathologies in juvenile idiopathic arthritis. Early detection and treatment of these common and potentially disabling lower limb pathologies are fundamental to achieving gold standard care for children with juvenile idiopathic arthritis. 2017 Paediatrics and Child Health Division (Royal Australasian College of Physicians)
The role of SmartWatch Technology in the provision of care for type 1 or type 2 Diabetes Mellitus or Gestational Diabetes: a systematic review.
(JMIR, 2023-12-03) Alvarez, Sergio; Fellas, Antoni; Wynne, Kate; Santos, Derek; Sculley, Dean; Acharya, Shamasunder; Navathe, Pooshan; Girones, Xavier; Coda, Andrea
Background: The use of Smart technology in the management of all forms of diabetes mellitus has grown significantly in the past ten years. Technologies such as the SmartWatch have been proposed as a method of assisting in the monitoring of blood glucose levels as well as other alert prompts such as medication adherence and daily physical activity targets. These important outcomes reach across all forms of diabetes and have the potential to increase compliance of self-monitoring with the aim of improving long term outcomes such as HbA1c. Objective: This systematic review aims to explore the literature for evidence of SmartWatch technology in type 1,2 and gestational diabetes. Methods: A systematic review was undertaken by searching Ovid MEDLINE and CINAHL databases. A second search using all identified keywords and index terms was performed on Ovid MEDLINE (January 1966 to August 2023), EMBASE (January 1980 to August 2023), Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, latest issue), CINAHL (from 1982), IEEE Xplore, and ACM Digital Libraries, and Web of Science databases. Results: Five studies were included for qualitative synthesis in this review, however, none of these studies were randomised clinical trials and published research is currently focusing on usability and feasibility. Conclusions: This systematic review has highlighted the lack of robust randomised clinical trials that explore the efficacy of SmartWatch technology in the management of patients with type 1, 2 and gestational diabetes.
