  • Potential electrochemical reactions provoked by prolonged electrical stimulation and neuromodulation: in vitro porcine model
    Jonathan Jenkin Tsui, Jeremy Hopkin Tsui
    Regional Anesthesia and Pain Medicine, 2025
    Recent neuromodulation studies used repurposed low-frequency (1–5 Hz) monophasic nerve localization stimulators of 200 µs up to 1 mA[1][1] or specialized high-frequency (100 Hz) biphasic chronic pain stimulators of 200 µs up to 30 mA[2][2] for acute pain management. Reactive particles (H+

  • The impact of relocation of chronic pain service from hospital setting to community centre on patient experience: a single-centre audit
    Jonathan Jenkin Tsui, Veronica Davey, Lesley Colvin
    British Journal of Pain, 2018
    Background and aims: The Lothian Chronic Pain Service relocated from a university teaching hospital (Western General Hospital (WGH)) to a community centre (Leith Community Treatment Centre (LCTC)) in 2015. Transportation and geographical location were noted by staff to be potential challenges that could negatively impact on the patient experience. The objective of this study is to evaluate how relocating pain clinic from an urban-based hospital to a peripheral community centre on patient experience. Methods: An assessment and audit of the impact of the relocation on the Patient-Reported Experience Measure (PREM) of pain services was conducted. Using a nationally developed questionnaire, the patient-reported experience from LCTC was prospectively collected in 2016 and was compared to historical data obtained from WGH in 2014 by National Health Service (NHS) Scotland. All patients attending Lothian Chronic Pain Service clinics were deemed eligible for the audit. Patient demographics were compared between the two data sets. The impact of patient deprivation on patient experience was investigated using the Scottish Index of Multiple Deprivation (SIMD16). Results: Data from 111 patients from LCTC were compared to 206 patients from WGH. Percentage of patients rating care as ‘excellent’ was found to be significantly greater at LCTC than WGH (0.0049). However, overall patient rating of care from LCTC was not significantly different from WGH data and ratings were higher at LCTC. No correlation was found between patient deprivation and PREM. Conclusion: There is no clear evidence that PREM was negatively affected by the move from a university teaching hospital to a community setting. As this only reported experiences of patients who attended the service, further studies may be warranted to investigate the impact of patient nonattendance.
  • Is top-down therapy a more effective alternative to conventional step-up therapy for crohn’s disease?
    Jonathan Jenkin Tsui
    Annals of Gastroenterology, 2018
    The management of Crohn's disease involves immunosuppressive protocols in a step-up approach that progresses through a therapeutic pyramid with several tiers of medication. Medications at the top are considered more potent but present greater risk. A new top-down approach to therapy inverts this procedure, using top-tier drugs for initial treatment. A critical appraisal of the current literature relating to top-down therapy was performed to evaluate its merit. A literature search was conducted on PubMed, Ovid, and PubMed Central to identify studies of the efficacy of top-down therapy. Papers were appraised critically using the Scottish Intercollegiate Guidelines Network score to evaluate current evidence for the use of top-down therapy. Nineteen studies were identified, including six randomized controlled trials, thirteen cohort studies, and two cost-benefit studies. Early combined therapy involving both biologics and immunomodulators was found to be effective at improving patient outcomes; however, early biologics alone were not shown to have a clear benefit over step-up therapy. Likewise, the early use of immunomodulators alone showed inconsistent results with respect to efficacy in terms of both remission and surgical outcomes. Evidence for application in pediatric populations was also inconclusive. The cost-benefit analyses found that top-down therapy merits investigation, as it proved to be economical given current data. Top-down therapy has the potential of being a viable alternative to step-up therapy, but further studies are needed to determine the most appropriate patients to receive this treatment.
  • The Frequency of Clinic Visits Was Not Associated with Medication Adherence or Outcome in Children with Inflammatory Bowel Diseases

    Canadian Journal of Gastroenterology and Hepatology, 2018
    Background. Medication nonadherence is a challenge in pediatric patients with inflammatory bowel diseases (IBD). Poor adherence can result in disease flare-ups, disease complicationstherapy escalation, and the need for corticosteroids. The aim was to determine if clinic visit frequency was associated with treatment adherence. Methods. A retrospective chart review of patients attending the Edmonton Pediatric IBD Clinic (EPIC) at the Stollery Children’s Hospital from January 2012 to December 2013 was completed. Correlations were made between frequency of clinic visit, percentage of prescriptions filled, percentage of requisitioned blood work completed, rural or urban residence, and steroid-free remission status of patients for the 6 months after the chart review. Results. 127 patients were reviewed with 82 patients diagnosed with Crohn’s disease (CD) and 46 with ulcerative colitis (UC) which included one IBD-Unclassified. Mean age at diagnosis is 9.17 years and median duration of follow-up is 3.2 years. Almost all patients on infliximab infusions received them “within window.” Immunomodulator median adherence rate was 88%. 5-ASA adherence was 82%. A median of 67% of patients had blood work completed as requested. Clinic visit frequency was not associated with adherence to blood work or to medications. Duration of disease was the only independent factor found to be associated with a reduction in blood work and immunomodulator adherence (“OR 0.86 and 95% CI: 0.74–0.99” and “OR 0.82 and 95% CI: 0.71–0.97”) per year, respectively. Patients who remained corticosteroid-free in the 6 months after the 2 years’ adherence review had an overall median medication adherence rate of 86% compared to only 53% for those who relapsed and required corticosteroids (p=0.01). Conclusion. Clinic visit frequency was not associated with patient adherence to medications or blood work. However, disease duration was found to be associated with medication adherence. Adherent patients were more likely to remain in steroid-free remission.
