Abstract
Background Complementary and alternative medicine (CAM) use is common in inflammatory bowel disease (IBD) patients and impacts compliance with conventional treatment. Gastroenterologists should understand the motivational factors of CAM use-factors that push patients away from standard therapy or pull towards CAM. Our study describes the motivations behind CAM use for IBD and evaluates differences between Crohn's disease (CD) and ulcerative colitis (UC) patients. Methods Retrospective cohort survey of patients over 18 years old with IBD, evaluated by gastroenterologists at a tertiary care referral centre from January 1 to December 31, 2019. Only patients who reported CAM use were included. Chi-square and independent t-tests were performed and P-value <0.05 was significant. Results Of the 230 completed surveys, 193 reported CAM use (CD: 57.5% vs UC: 42.5%). Demographics, disease duration, and hospitalizations were similar, but CD patients had lower SIBDQ scores (CD: 48.1 vs UC: 53.5, P < 0.001). Both groups were largely influenced by their social network to use CAM (CD: 33% vs UC: 31.3%) and did not feel well informed about CAM (87.4%). CD and UC patients had similar push and pull factors. Push factors included lack of improvement (39%) and side effects (20%) with conventional treatment. Pull factors included the desire for a holistic approach (21%) and to improve mood (35%). UC patients wanted a natural approach to treat their IBD, which nearly reached significance (P = 0.049). Most patients hoped fatigue 62.7%, and diarrhoea 61.7% would improve with CAM, but more CD patients wanted to improve their appetite (P = 0.043). Conclusion Despite differences in QoL, push and pull motivations for CAM use did not differ between CD and UC patients. Most users do not feel well informed of CAM and ongoing dialogue is important for patient-centred care.

Abstract
Background Despite infliximab biosimilars becoming widely used in inflammatory bowel disease (IBD) patients, real-world non-medical switching is sparse. A biosimilar non-medical switch was launched in British Columbia in 2019, the first Canadian province to do so, from Remicade to an approved biosimilar (CT-P13 or SB2). Aims This study aims to obtain real-world evidence evaluating the clinical outcomes of non-medical switching from Remicade to the infliximab biosimilars. Methods This is a retrospective observational study of stable IBD patients from the IBD Centre of BC who underwent the non-medical infliximab switch. The primary outcome is treatment continuation at 12 ± 2 months post-switch. Secondary outcomes include frequency of loss of response, adverse events, and immunogenicity within the first 12 months post-switch. A control group of patients maintained on the originator served as a comparison. Results Patients in the biosimilar switch group (n = 264) and originator group (n = 99), show similar demographics and disease characteristics. There was no difference in infliximab continuation between the biosimilar group (94.9%) and the originator group (90.1%) (P = 0.18). Reasons for discontinuation of infliximab included loss of response (4.04% vs 4.91%), immunogenicity (1.01% vs 0.75%), or adverse effect (1.01% vs 2.3%) in the infliximab originator vs biosimilar switch group, respectively. Similarly, no differences in safety or efficacy were observed between patients switched to CT-P13 or SB2. Conclusions Non-medical biosimilar switch of infliximab demonstrates similar clinical outcomes compared to originator molecule continuation for therapy of IBD. These data support the safety and efficacy of non-medical infliximab switching in IBD patients.

Live Rotavirus Vaccination Appears Low-risk in Infants Born to Mothers With Inflammatory Bowel Disease on Biologics. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00677-3. [PMID: 39089515 DOI: 10.1016/j.cgh.2024.07.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 06/22/2024] [Accepted: 07/03/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND & AIMS Biologic therapies in the context of inflammatory bowel disease and pregnancy lead to improved maternal and fetal outcomes. Placental transfer results in detectable drug concentrations in infants. Rotavirus infection results in diarrheal related hospitalizations; however, the live oral vaccine is not currently recommended in biologic exposed infants. The aim of this study was to assess the effect of maternal biologic therapies on the infant immune system and safety of live rotavirus vaccination in biologic-exposed infants. METHODS Biologic-exposed infants underwent standardized clinical assessments, drug concentration, and immune function testing (complete blood count, differential, immunoglobulin levels, extended B-cell and T-cell subset enumeration, Recent Thymic Emigrants, regulatory T-cell numbers, mitogen stimulation assays, and review of T-cell Receptor Excision Circles in the newborn screen). Rotavirus vaccine-specific adverse effects following immunizations up to 42 days post the last dose of the vaccine series were recorded. RESULTS There were 57 infants born to 52 mothers with inflammatory bowel disease exposed to infliximab (n = 21), adalimumab (n = 19), vedolizumab (n = 10), and ustekinumab (n = 7) in the third trimester for a median of 39 weeks (interquartile range, 38-39 weeks) at delivery. Immunologic assessments validated for age were normal in all infants despite median infliximab concentrations of 6.1 ug/mL (range, 0.4-28.8 ug/mL), adalimumab concentrations of 1.7 ug/mL (range, 0.7-7.9 ug/mL), ustekinumab concentrations of 0.6 ug/mL (range, 0-1.1), and undetectable for vedolizumab at 10.7 weeks (interquartile range, 9.4-12.4) of age. The live oral rotavirus vaccine series was provided to 50 infants with the first dose given at a median of 13 weeks of age. No adverse effects following immunization were reported. CONCLUSION Immune function testing was normal, and administration of live rotavirus vaccination appeared low-risk in biologic-exposed infants irrespective of circulating drug levels.

Despite Increased Disease Activity, Women who Attended a Dedicated Inflammatory Bowel Disease and Pregnancy Clinic Had Infants With Higher Apgar Scores: A Population-Based Study.

Abstract
BACKGROUND Attendance at a subspecialty pregnancy clinic for women with inflammatory bowel disease (IBD) improves disease-specific pregnancy knowledge. We examined the impact of attendance at a dedicated IBD-pregnancy clinic on IBD and perinatal outcomes. METHODS Using linked administrative databases in Alberta, Canada (2012-2019), we identified 1061 pregnant women with IBD who delivered singleton liveborn infants in-hospital who did (n = 314) and did not attend (n = 747) the clinic. Propensity score weighted multivariable log-binomial and multinomial logistic regression models were used to determine the risk of IBD and perinatal outcomes. RESULTS The median number of clinic visits was 3 (Q1-Q3, 3-5), with 34.7% completing a preconception consultation. A greater proportion of women who attended lived near the clinic, were nulliparous, had a disease flare prior to pregnancy, and were on maintenance IBD medication (P < .05). Women who attended had increased risks of a disease flare during pregnancy (adjusted risk ratio [aRR], 2.02; 95% CI, 1.45-2.82), an IBD-related emergency department visit during pregnancy (aRR, 2.66; 95% CI, 1.92-3.68), and cesarean delivery (aRR, 1.78; 95% CI, 1.23-2.57). Despite this, clinic attendees had a decreased risk of delivering an infant with a low Apgar score at 1 minute (risk ratio [RR], 0.49; 95% CI, 0.32-0.76) and 5 minutes (RR, 0.32; 95% CI, 0.12-0.87). CONCLUSIONS Women who attended a dedicated IBD-pregnancy clinic were more likely to have a disease flare prior to pregnancy, reflecting a more severe disease phenotype, but had similar perinatal outcomes and infants with better Apgar scores at birth. Our study suggests the value of these subspecialty clinics in providing enhanced IBD-specific prenatal care.

High-definition chromoendoscopy results in more significant dysplasia detection than white light endoscopy with random biopsies in ulcerative colitis patients: A single-center retrospective study. Medicine (Baltimore) 2024; 103:e36836. [PMID: 38306575 PMCID: PMC10843359 DOI: 10.1097/md.0000000000036836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 12/12/2023] [Indexed: 02/04/2024] Open
Abstract
The goal of this study was to determine whether high-definition white light endoscopy with random biopsies (HD-WLR) or chromoendoscopy (HDCE) yielded a higher dysplasia detection rate in ulcerative colitis patients. Ulcerative colitis (UC) patients have a 2.4-fold increased future risk of developing colorectal cancer compared to the general population and require careful dysplasia screening modalities. Both HD-WLR and HDCE are regularly used, and recent guidelines do not suggest a preference. UC patients who underwent dysplasia surveillance at our site between January 2019 and 2021 were retrospectively reviewed. We calculated the dysplasia detection rate of both techniques at the first CRC screening colonoscopy. Eighteen dysplastic lesions were detected in total, 3 by HD-WLR and fifteen by HDCE. Dysplasia was detected in 4% (3/75) and 20% (15/75) of UC patients by HD-WLR and HDCE respectively, with significantly fewer biopsies (4.44 ± 4.3 vs 29.1 ± 13.0) required using the former. HD-WLR detected 2 polypoid and one non-polypoid lesion, while HDCE detected eleven polypoid and 4 non-polypoid lesions. No invisible dysplasia or colorectal cancer was detected. Screening was performed at 10.8 ± 4.8 and 9.72 ± 3.05 years following UC diagnosis for HDCE and HD-WLR respectively. Median withdrawal time was 9.0 ± 2.7 minutes (HD-WLR) vs 9.6 + 3.9 minutes (HDCE). HDCE is associated with higher dysplasia detection rates compared to HD-WLR in a UC patient population. Given the former technique is less tedious and costly, our findings complement existing studies that suggest HDCE may be considered over HD-WLR for UC dysplasia surveillance.

Abstract
This narrative review explores the management of Inflammatory Bowel Disease (IBD) during pregnancy, emphasizing its unique challenges to maternal and fetal health, particularly within the Canadian Gastroenterology setting. Seven key principles are highlighted: 1) Preconception counselling, aiming for steroid-free remission confirmed by objective markers, should be routine for female IBD patients. 2) Medication safety, with an eye to future pregnancies, should be addressed upon initiation. Methotrexate and small molecules are contraindicated during pregnancy, while most 5-ASA therapies, biologics, and thiopurines can be continued throughout pregnancy and breastfeeding. Steroids, though not without risks, can be utilized if necessary. 3) Routine monitoring during remission should include serum biomarkers and fecal calprotectin each trimester. 4) Routine endoscopy and imaging are not required, but if indicated, lower GI endoscopy, ultrasound, and unenhanced MRI can be used. Computed tomography and gadolinium enhanced MRI should be avoided. 5) Caesarean section is advised for patients with previous ileal pouch surgeries or active perianal disease, but other patients should follow obstetric indications for delivery. 6) Postpartum period may see more active disease, requiring continued monitoring. Breastfeeding is encouraged, and routine childhood vaccinations are advised, but live vaccinations in the first 6 months warrant detailed review. 7) Complex IBD patients may benefit from a multidisciplinary approach with robust communication between gastroenterologists and obstetricians.

Abstract
Background Thiopurines are commonly used to treat inflammatory bowel disease (IBD). Thiopurines are considered safe throughout pregnancy. However, a published study suggested the risk of neonatal anemia was increased if exposed to thiopurines in utero. This prospective cohort study aimed to determine if there is an increased risk of cytopenia among infants born to pregnant people with IBD, exposed or unexposed to thiopurines, compared to infants born to those without IBD. Methods Pregnant IBD patients, with and without thiopurine exposure, and one cohort of control individuals were recruited over a 5-year period. Consenting individuals completed a questionnaire and infants had a complete blood cell count at the newborn heel prick. Anemia was defined as hemoglobin (Hb) < 140g/L. Descriptive statistics were used to characterize the study population. Fisher exact tests were used to examine differences in outcomes between groups, a P-value of < 0.05 was deemed significant. Results Three cohorts were recruited: 19 IBD patients on thiopurines, 50 IBD patients not on thiopurines, and 37 controls (total of 106). Neonatal median Hb was not different with 177g/L (IQR 38g/L) for the IBD thiopurine group, 180.5g/L (IQR 40g/L) for the IBD non-thiopurine group, and 181g/L (IQR 37g/L) for the controls. Nineteen infants (18%) were cytopenic with 12 (11%) anemic, 6 (5.6%) thrombocytopenic, and 1 (0.94%) lymphopenic. Thiopurine exposure was only in one, mildly anemic, infant. Conclusions These findings further support physicians and IBD patients contemplating pregnancy that current guidelines recommending thiopurine adherence do not lead to increased perinatal risk of anemia or cytopenia.

Abstract
Background Gender inequalities persist in medicine, particularly in some speciality fields where fewer women are employed. Although previous research has suggested potential interventions to broadly address gender inequality in medicine, no research has focused on interventions in the field of gastroenterology. The purpose of this research was to engage women in the field of gastroenterology in Canada, to identify interventions with potential to be effective in addressing gender inequality. Methods A World Café was hosted in 2019 to discuss gender inequality and interventions in gastroenterology. Twelve women employed in the field of gastroenterology (i.e. physicians, nurses, research staff, and trainees) were purposively recruited and participated in the event. The discussion rounds were audio-recorded, transcribed, and thematic analyses was conducted using Braun and Clarke's principles. Results Three key themes identifying potential interventions to address gender inequality in gastroenterology were generated: (1) Education; (2) Addressing institutional structures and polices; and 3) Role modelling and mentorship. Participants indicated that interventions should target various stakeholders, including both women and men in gastroenterology, young girls, patients, and administrators. Conclusion Many of the interventions identified by participants correspond with existing research on interventions in general medicine, suggesting that institutional changes can be made for maximum effectiveness. Some novel interventions were also identified, including publicizing instances of gender parity and supporting interventions across the educational and professional lifecourse. Moving forward, institutions must assess their readiness for change and evaluate existing policies, programs, and practices for areas of improvement.

Abstract
INTRODUCTION Central venous catheter (CVC) placement is commonly performed in children. We aim to develop simple formulas to predict CVC intravascular length to minimise radiation exposure associated with the procedure. METHODS 124 paediatric patients who received tunnelled neck CVCs and subsequent CT thorax at Hong Kong Children's Hospital from January 2020 to July 2022 were reviewed retrospectively. Formula development cohorts were subdivided by insertion sites-9 right external jugular vein (REJV), 41 right internal jugular vein (RIJV), 14 left external jugular vein (LEJV), 10 left internal jugular vein (LIJV). Using measurements from CT by two radiologists, formulas predicting the CVC intravascular length based on height and insertion sites were developed using a linear regression model. These formulas were tested with validation cohorts (10 randomly selected cases in REJV and RIJV groups respectively). Validation cohorts were not available for LEJV and LIJV groups due to small sample sizes. RESULT The goodness-of-fit (R^2) of all formulas are above 0.8. In the validation cohorts, the REJV formula was predictive of intravascular CVC length within 1 cm in 70% of CVC with mean absolute difference of 0.63 cm (SD 0.48 cm), and the RIJV formula was predictive of intravascular CVC length within 1 cm in 80% of CVC with mean absolute difference of 0.67 cm (SD 0.53 cm). CONCLUSION Intravascular CVC length can be estimated using simple formulas based on height and insertion sites. Further prospective validation of the LEJV and LIJV formulas is needed.

Abstract
Background Ulcerative colitis (UC) is an inflammatory bowel disease that results in inflammation of the colonic mucosa, leading to abdominal pain, rectal bleeding, weight loss, and diarrhea. This chronic inflammation results in a 2.4-fold increased future risk of developing colorectal cancer (CRC) in UC patients compared to the general population. Thus, careful dysplasia screening modalities are required to prevent progression to CRC. Currently, both high-definition white light endoscopy with non-targeted biopsies (HD-WLR) and dye-spray chromoendoscopy (HDCE) are regularly used across Canada for dysplasia surveillance given existing research has been inconclusive regarding superiority of one particular method, and that recent guidelines do not suggest a preference. Purpose The primary objective of this study was to determine which surveillance modality yielded a higher dysplasia detection rate in UC patients, both by calculating the total number of dysplastic lesions detected, as well as calculating the number of patients with at least one dysplastic lesion detected using either technique. Method We conducted a single-centre retrospective chart review of 150 UC patients who underwent dysplasia surveillance at our site between January 2019-2021. We calculated the dysplasia detection rate of both techniques at the time of the first CRC screening colonoscopy. Result(s) Eighteen dysplastic lesions were detected in total, three by HD-WLR and fifteen by HDCE. Dysplasia was detected in 4% (3/75) and 14.5% (15/75) of UC patients by HD-WLR and HDCE respectively, with significantly fewer biopsies (4.44 + 4.3 vs 29.1 + 13.0) required. HD-WLR detected two polypoid and one non-polypoid lesion, while HDCE detected eleven polypoid and four non-polypoid lesions. No invisible dysplasia or colorectal cancer was detected. Screening was performed at 10.8 + 4.8 and 9.72 + 3.05 years following UC diagnosis for HDCE and HD-WLR respectively. Median withdrawal time was 9.0 + 2.7 min (HD-WLR) vs 9.6 + 3.9min (HDCE). Image ![]()
Conclusion(s) HDCE resulted in higher dysplasia detection rates compared to HD-WLR in a UC patient population. Given the former technique is less tedious and costly, our findings suggest HDCE should be considered over HD-WLR for UC dysplasia surveillance.

Abstract
Background Inflammatory Bowel Disease (IBD) is a chronic inflammatory condition of the bowel which includes ulcerative colitis (UC), Crohn’s disease (CD) or unspecific IBD (IBDu). Adalimumab (ADA), a humanized monoclonal IgG antibody against tumour necrosis factor-alpha (TNFa), is an effective treatment for IBD. HumiraTM is an anti-TNFa agent that was approved by Health Canada for the treatment of IBD. In May of 2019, the British Columbia government pharmaceutical benefit plan implemented a biosimilar initiative in May 2019, mandating a non-medical switch from HumiraTM to one of the biosimilar drugs. Purpose We aimed to evaluate the real-world experience on the comparative safety and effectiveness of adalimumab biosimilar therapy after a mandatory, non-medical switch. Method We performed a retrospective chart review of all patients with IBD who either remained on HumiraTM or were switched to an adalimumab biosimilar agent, Idacio, at three tertiary care centres. Patients’ demographic data, disease status including CRP and fecal calprotectin before and after switch, and hospital visits or admission after switch were collected. Statistical analysis was performed using ANOVA and t-test. Result(s) Of the 191 patients included in the study, 145 patients underwent the provincial mandated switch from HumiraTM to a biosimilar agent, Idacio® , whereas 46 patients remained on HumiraTM. The median age at IBD diagnosis was 27 years (range 3-76 years), and at biosimilar switch was 43.5 years (15-78 years). Median disease duration prior to biosimilar switch was 13.5 years (range 0-69 years). 55.1% of patients were male, and 12.9% of patients were active smokers. CD was found in 78.9% of patients, and 19.9% of patients had UC. After biosimilar switch, adverse events, such as rash, nausea, or vomiting, were noted in 10 patients in the biosimilar group, and 7 patients required switch back to HumiraTM. All patients in the HumiraTM group stayed on that therapy. One patient stopped the biosimilar agent due to development of a new cancer requiring chemotherapy. None of the patients required IBD-related emergency department visit or hospital admission. Additionally, there was no difference in CRP or fecal calprotectin values measured before and after the biosimilar switch, and when compared to the patients who stayed on HumiraTM (p=0.48, and p=0.142, respectively). Conclusion(s) We conclude that the clinical benefit of HumiraTM was sustained after a non-medical switch to an adalimumab biosimilar. There was no risk of relapse, emergency visit, or hospital admission seen in this study. This is the first Canadian study to establish the safety and efficacy of switch to non-medical switch to an adalimumab biosimilar agent.

Modified Mayo score versus Mayo score for evaluation of treatment efficacy in patients with ulcerative colitis: data from the tofacitinib OCTAVE program. Therap Adv Gastroenterol 2022; 15:17562848221136331. [PMID: 36506749 PMCID: PMC9726836 DOI: 10.1177/17562848221136331] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Accepted: 10/13/2022] [Indexed: 12/12/2022] Open
Abstract
Objectives The subjectivity of the Physician Global Assessment (PGA) is a limitation of the Mayo score in assessing severity of ulcerative colitis (UC). We compared treatment efficacy using endpoint definitions based on modified Mayo (mMayo) score, versus those based on Mayo score, using data from the tofacitinib OCTAVE program. Design This post hoc analysis included data from two 8-week induction studies (OCTAVE Induction 1 and 2) and a 52-week maintenance study (OCTAVE Sustain). Methods Remission and clinical response [with nonresponder imputation (NRI)] were assessed using mMayo (without PGA) and Mayo scores, and further stratified by prior tumor necrosis factor inhibitor (TNFi) failure status. Results At week 8 of OCTAVE Induction 1 and 2, remission rates with placebo and tofacitinib 10 mg twice daily (BID), respectively, were 7.7% and 24.8% (mMayo) and 6.0% and 17.6% (Mayo). At week 52 of OCTAVE Sustain, remission rates with placebo, tofacitinib 5 and 10 mg BID, respectively, were 12.1%, 35.9%, and 42.1% (mMayo) and 11.1%, 34.3%, and 40.6% (Mayo). A statistically significant (p < 0.05) treatment effect of tofacitinib versus placebo was observed for remission and clinical response at all time points, regardless of scoring definition or prior TNFi failure status. Conclusions A significant effect of tofacitinib versus placebo was demonstrated across efficacy endpoints using mMayo score, consistent with previously reported data using Mayo score. Treatment effect sizes were generally similar regardless of scoring definition. This observation may help contextualize tofacitinib therapy outcomes with those of new UC therapies and support the use of Mayo score-based endpoints in UC clinical trials.

Abstract
BACKGROUND Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The induction dose is 10 mg twice daily (b.d.), whilst for maintenance therapy, the lowest effective dose should be used. AIM To examine published evidence on the two tofacitinib dosing strategies used in UC treatment, including expert interpretation of the data and how they could inform clinical practice. METHODS The use of tofacitinib 5 or 10 mg b.d. was assessed using data from the tofacitinib UC clinical programme in the context of different clinical scenarios. We include experts' opinions on the clinical implications of dose adjustment to inform the benefit/risk of using tofacitinib 5 or 10 mg b.d., based on clinical scenarios and real-world data. RESULTS Factors to consider when adjusting the tofacitinib dose include disease severity, comorbidities and previous biological exposure. The endoscopic subscore can determine whether a patient is a good candidate for dose reduction. Following disease relapse, the response can be recaptured in a substantial number of patients with a dose increase. Furthermore, data are now published showing real-world use of tofacitinib and, so far, these are consistent with data from the clinical trials. CONCLUSION Clinicians must consider the benefit/risk balance of tofacitinib 10 versus 5 mg b.d. in terms of dose-related side effects, as well as the safety implications of undertreating active disease. All patients should be closely monitored for disease relapse following dose reduction or interruption for early recapture of response.

Abstract
Although significant progress relating to professional equality among men and women in medicine has been made over the past few decades, evidence derived from the medical literature suggests that inequity persists with respect to income, attainment of leadership positions, and professional advancement. These inequities have been observed to be more pronounced in gastroenterology. Literature relating to gender-specific barriers to professional equity in gastroenterology is limited. This qualitative study explored perceived barriers to professional equality among women in gastroenterology in Canada through focus groups using a World Café Approach. Several perceived barriers to professional equality were identified. Identification of barriers to professional equality is an important first step to creating meaningful interventions that address the root causes of gender-related inequity in gastroenterology.

Abstract
Abstract
Introduction
Cauda Equina Syndrome(CES) is a potentially disabling condition caused by compression of the thecal sac in the lumbar spine. Traditional teaching suggests red flags include back pain, sciatica, saddle anaesthesia and bladder disturbance. Current guidelines from the British Association of Spinal Surgeons recommend prompt investigation with MRI should these symptoms be present.
Method
A retrospective electronic case note review was undertaken from a one-year period to identify patients referred to the on call orthopaedic team with suspected CES and were investigated with MRI. Notes were reviewed for the presence of each clinical characteristic and correlated with MRI findings.
Results
334 referrals underwent urgent MRI with 25 scans showing CES. Poor statistical association was observed with unilateral leg pain (sensitivity 0.28, specificity 0.48), back pain (sensitivity 0.92, specificity 0.13) and bladder dysfunction (sensitivity 0.72, specificity 0.36). Much closer statistical association was seen with bilateral leg pain (sensitivity 0.6, specificity 0.7, OR 5.03, 95% CI 2.16-11.68, p0.0002), leg weakness (sensitivity 0.68, specificity of 0.72, OR 5.35, 95% CI 2.23-12.85, p0.0002), leg sensory deficit (sensitivity 0.72, specificity 0.60, OR 3.79, 95% CI 1.54-9.36, p0.004) and altered perianal sensation (sensitivity 0.6, specificity 0.67, OR 3.03, 95% CI 1.31-6.99, p 0.009)
Conclusions
The diagnostic accuracy for some conventional red flag characteristics in CES is low. In our series back pain, unilateral sciatica and bladder disturbance showed low predictive value while bilateral sciatica, saddle anesthesia and lower limb sensorimotor deficits showed closer association and therefore should be closely evaluated for when reviewing such patients.

Abstract
Background Research has indicated a lack of disease-specific reproductive knowledge among patients with Inflammatory Bowel Disease (IBD) and this has been associated with increased “voluntary childlessness”. Furthermore, a lack of knowledge may contribute to inappropriate medication changes during or after pregnancy. Decision aids have been shown to support decision making in pregnancy as well as in multiple other chronic diseases. A published decision aid for pregnancy in IBD has not been identified, despite the benefit of pre-conception counselling and patient desire for a decision support tool. This study aimed to develop and test the feasibility of a decision aid encompassing reproductive decisions in the setting of IBD. Methods The International Patient Decision Aid Standards were implemented in the development of the Pregnancy in IBD Decision Aid (PIDA). A multi-disciplinary steering committee was formed. Patient and clinician focus groups were conducted to explore themes of importance in the reproductive decision-making processes in IBD. A PIDA prototype was designed; patient interviews were conducted to obtain further insight into patient perspectives and to test the prototype for feasibility. Results Issues considered of importance to patients and clinicians encountering decisions regarding pregnancy in the setting of IBD included fertility, conception timing, inheritance, medications, infant health, impact of surgery, contraception, nutrition and breastfeeding. Emphasis was placed on the provision of preconception counselling early in the disease course. Decisions relating to conception and medications were chosen as the current focus of PIDA, however content inclusion was broad to support use across preconception, pregnancy and post-partum phases. Favourable and constructive user feedback was received. Conclusions The novel development of a decision aid for use in pregnancy and IBD was supported by initial user testing.

Abstract
BACKGROUND Air pollution has been associated with an increase in cardiovascular diseases incidence. To evaluate whether air pollution can accelerate atherogenic processes, we assessed the effects of air pollution on important surrogate markers of atherosclerosis [brachial flow-mediated dilation (FMD) and carotid intima-media thickness (IMT)]. METHODS A total of 1656 Han Chinese (mean age 46.0 + 11.2 years; male 47%) in Hong Kong, Macau, Pun Yu, Yu County and the 3-Gorges Territories (Yangtze River) were studied between 1996 and 2007 [Chinese Atherosclerosis in the Aged and Young Project (the CATHAY Study)]. Cardiovascular risk profiles were evaluated. Particulate matter with an aerodynamic diameter <2.5 µm (PM2.5) parameters were computed from satellite sensors. Brachial FMD and carotid IMT were measured by ultrasound. RESULTS Health parameters [age, gender, body mass index, waist : hip ratio (WHR) and glucose)] were similar in lowest and highest PM2.5 exposure tertiles, systolic and diastolic blood pressures and triglycerides were higher (P < 0.001) and low-density cholesterol (LDL-C) was lower in the top PM2.5 tertile (P < 0.001). Brachial FMD [7.84 ± 1.77, 95% confidence interval (CI) 7.59-8.10%, vs 8.50 ± 2.52, 95% CI 8.23-8.77%, P < 0.0001) was significantly lower and carotid IMT (0.68 ± 0.13 mm, 95% CI 0.67-0.69 mm vs 0.63 mm ± 0.15 mm 95% CI 0.62-0.64 mm; P < 0.0001) was significantly thicker in the top PM2.5 tertile compared with the lowest tertile. On multiple regression, FMD was inversely related to PM2.5 (beta = 0.134, P = 0.015) independent of gender, age and blood pressure (model R2 = 0.156, F-value = 7.6, P < 0.0001). Carotid IMT was significantly correlated with PM2.5 exposure (beta = 0.381, P < 0.0001) independent of age, location, gender, WHR, blood pressure and LDL-C (model R2 = 0.408, F-value = 51.4, P-value <0.0001). CONCLUSIONS Air pollution is strongly associated with markers of early atherosclerosis, suggesting a potential target for preventive intervention.

Abstract
Abstract
Background
Inflammatory bowel disease (IBD) in patients with primary sclerosing cholangitis (PSC) is characterized by pancolitis with rectal sparing and is associated with an increased risk of colorectal and biliary malignancies. Currently, pharmacologic management of IBD in the setting of PSC is the same as in IBD alone.
Aims
To assess patterns in medical therapy, and incidence of adverse outcomes in patients with concomitant IBD and PSC.
Methods
A retrospective review was conducted on all PSC-IBD patients followed between January 2010 and June 2018. The Endoscopic Mayo Score was used to grade IBD severity in PSC-ulcerative colitis (UC).
Results
69 patients were identified, 44 (63.8%) were male. The mean ages of IBD and PSC diagnosis were 28.6 (SD 14.9) and 37.0 (SD 18.9) years, respectively. The median length of follow up was 12 (range 2–49) years. 52 (75.4%) patients had UC, and 17 (24.6%) had Crohn’s disease (CD). 28 (87.5%) PSC-UC patients had pancolitis, and 4 (12.5 %) had proctitis. Among those with pancolitis, 8 (28.6%) had relative rectal sparing. 4 (14.3%) patients had more severe inflammation proximally, whereas only 1 (3.6%) had more severe distal inflammation. 23 (82.1%) patients had the same degree of inflammation throughout. 14 (93.3%) PSC-CD patients had colitis/ileocolitis and 1 (6.7%) had ileitis. Among those with PSC-UC, 16 (50.0%), 12 (37.5%), and 4 (12.5%) patients had grade 1, 2, and 3 disease, respectively. 62 (89.9%) PSC-IBD patients were treated with aminosalicylates, and 26 (37.7%) with biologics at some point in their IBD course. 26 (37.7%) were treated with aminosalicylates alone. 4 (5.8%) did not require any IBD therapy. Cholangiocarcinoma, colorectal cancer, and gallbladder cancer developed in 8 (11.6%), 1 (1.4%), and 1 (1.4%) PSC-IBD patients, respectively. 16 (23.2%) patients required partial or total colectomy. Indication for surgery was inflammation or stenosis, dysplasia, and neoplasia in 13 (81.3%), 2 (12.5%), and 1 (6.3%) patients, respectively.
Conclusions
The majority of this cohort had UC with mild disease activity. Pancolitis was common, with frequent rectal sparing and more severe right-sided inflammation. Despite the predominance of low-grade colitis, a large portion of patients required treatment with biologics. The incidence of adverse outcomes underscores the need for strict adherence to recommended surveillance practices. Low grade endoscopic activity, typical of the quiescent IBD course in PSC-IBD, may mask low grade histologic inflammation, which in turn may contribute to the increased risk of colonic neoplasia. Further studies are needed to determine the best management strategy for IBD in patients with PSC.

Abstract
Background Pregnant women with inflammatory bowel disease (IBD) are more likely than the general pregnant population to experience adverse maternofetal outcomes, especially if the disease is active at the time of conception and during pregnancy. Elevated stress is often seen in patients with chronic diseases and could account for these outcomes. Salivary cortisol and alpha‐amylase (sAA) are novel biomarkers of stress, reflecting the hypothalamic‐pituitary‐adrenal (HPA) axis and sympathetic nervous system, respectively. Our aim in this pilot study was to assess stress differences between pregnant women with inactive IBD and matched controls using psychometric questionnaires and salivary biomarker measures. Methods Thirteen pregnant women with quiescent IBD (6 Crohn's disease, 7 ulcerative colitis) were matched (1:3) to 39 expectant mothers without IBD by parity and gestational age. Participants completed several psychometric questionnaires assessing stress, and salivary cortisol and sAA were collected as objective biomarkers of stress during pregnancy. Results Pregnant women with quiescent IBD did not demonstrate significant differences on any psychometric measures of stress or salivary biomarker measures when compared with controls (all P > 0.05). Pregnant women with quiescent IBD demonstrated similar cortisol and sAA awakening responses (both P > 0.05) and total levels of cortisol and sAA production (both P > 0.05) when compared with controls. Conclusions Pregnant women with well‐controlled IBD do not experience demonstrable differences in psychological stress or dysregulation of salivary stress biomarkers when compared with non‐IBD controls. The effect of chronic disease may be evaluated in future studies by including a comparative group of pregnant women with active IBD.

Abstract
Abstract
Background
Given a significant proportion of women with inflammatory bowel disease (IBD) are of child-bearing age, the development of a pregnancy IBD decision aid would benefit patients and clinicians. Lack of IBD-specific reproductive knowledge has been associated with increased “voluntary childlessness” and may contribute to inappropriate medication changes during or after pregnancy. Decision aids support decision making in pregnancy in general, as well as in multiple other chronic diseases. However existing literature has not identified such a resource for women with IBD.
Aims
To develop a decision aid to improve decision making regarding preconception and pregnancy in IBD among women with IBD.
Methods
We followed the International Patient Decision Aids Standards (IPDAS). A steering committee of Canadian and Australian health care professionals with an interest in IBD management in pregnancy, in addition to patient representatives, was established. Themes chosen for discussion included inheritance, fertility, nutrition, medications, mode of delivery, breastfeeding, infant health. Initial patient and clinician focus groups were conducted and responses recorded with written/audio mediums. We developed an electronic PIDA draft that incorporates individualised information (type of IBD, pre-conception or pregnant, surgical history, medications) in personalized decision making. Further patient focus groups and interviews were conducted to obtain user opinion of the PIDA draft.
Results
In July 2017, patient and clinician focus groups were conducted at a Canadian site. Three patients (pre-conception) attended the focus group. Patient concerns - impact of disease and surgery on fertility and preterm delivery; impact of drug therapies on the fetus/ infant; impact of active disease on maternal and fetal/infant health. The clinician focus group included 3 IBD specialists, 2 IBD fellows, 2 IBD nurses, an obstetrician and a neonatal intensivist. Clinician concerns - absence of pre-conception counselling and lack of patient understanding about the impact of disease activity and IBD medication use in pregnancy. Additional patient feedback obtained through interviews (n=15) at two Canadian sites since March 2019 regarding the current electronic PIDA was positive, with comments about content, personalization, readability and unbiased presentation. Suggestions were made for inclusion of additional content such as impact of IBD on sexual function, laboratory changes during pregnancy, and timing of medications post-partum.
Conclusions
The pre and post PIDA design patient and clinician focus groups and interviews affirmed the role for PIDA. Main decisions considered necessary to address included ideal timing of conception pending disease activity, management of medications, and delivery methods. Ongoing user feedback will be obtained at Australian and Canadian sites during planned alpha testing.

Abstract
Background We assessed whether the presence and severity of common cancer symptoms are associated with the health utility score (hus) generated from the EQ-5D (EuroQol Research Foundation, Rotterdam, Netherlands) in patients with cancer and evaluated whether it is possible pragmatically to integrate routine hus and symptom evaluation in our cancer population. Methods Adult outpatients at Princess Margaret Cancer Centre with any cancer were surveyed cross-sectionally using the Edmonton Symptom Assessment System (esas) and the EQ-5D-3L, and results were compared using Spearman correlation coefficients and regression analyses. Results Of 764 patients analyzed, 27% had incurable disease. We observed mild-to-moderate correlations between each esas symptom score and the hus (Spearman coefficients: -0.204 to -0.416; p < 0.0001 for each comparison), with the strongest associations being those for pain (R = -0.416), tiredness (R = -0.387), and depression (R =-0.354). Multivariable analyses identified pain and depression as highly associated (both p < 0.0001) and tiredness as associated (p = 0.03) with the hus. The ability of the esas to predict the hus was low, at 0.25. However, by mapping esas pain, anxiety, and depression scores to the corresponding EQ-5D questions, we could derive the hus using partial esas data, with Spearman correlations of 0.83-0.91 in comparisons with direct EQ-5D measurement of the hus. Conclusions The hus derived from the EQ-5D-3L is associated with all major cancer symptoms as captured by the esas. The esas scores alone could not predict EQ-5D scores with high accuracy. However, esas-derived questions assessing the same domains as the EQ-5D-3L questions could be mapped to their corresponding EQ-5D questions to generate the hus, with high correlation to the directly measured hus. That finding suggests a potential approach to integrating routine symptom and hus evaluations after confirmatory studies.

Abstract
Increasing uptake of biologic therapy has contributed to declining surgical rates for inflammatory bowel disease (IBD). However, a significant number of patients on biologic therapy will go on to require surgery. The literature is conflicted with regard to the preoperative management of biologic therapy before urgent or elective IBD surgery. This article reviews the available data on postoperative complications following preoperative treatment with anti-tumor necrosis factor alpha therapy, anti-integrin therapy, and anti-interleukin therapy.
