Abstract
BACKGROUND & AIMS Significant variability exists in colonoscopy quality indicators, including adenoma detection rate (ADR). We synthesized evidence from randomized trials in a network meta-analysis on interventions to improve colonoscopy quality. METHODS We included trials from database inceptions to September 25, 2023, of patients undergoing screening-related colonoscopy and presented efficacies of interventions within domains (periprocedural parameters, endoscopist-directed interventions, intraprocedural techniques, endoscopic technologies, distal attachment devices, and additive substances) compared to standard colonoscopy. The primary outcome was ADR. We used a Bayesian random-effects model using Markov-chain Monte Carlo simulation, with 10,000 burn-ins and 100,000 iterations. We calculated odds ratios with 95% credible intervals and present surface under the cumulative ranking (SUCRA) curves. RESULTS We included 124 trials evaluating 37 interventions for the primary outcome. Nine interventions resulted in statistically significant improvements in ADR compared to standard colonoscopy (9-minute withdrawal time, dual observation, water exchange, iScan, linked color imaging, computer-aided detection, Endocuff, Endocuff Vision, and oral methylene blue). Dual observation (SUCRA, 0.84) and water exchange (SUCRA, 0.78) ranked highest among intraprocedural techniques; iScan (SUCRA, 0.95), linked color imaging (SUCRA, 0.85), and computer-aided detection (SUCRA, 0.78) among endoscopic technologies; WingCap (SUCRA, 0.87) and Endocuff (SUCRA, 0.85) among distal attachment devices and oral methylene blue (SUCRA, 0.94) among additive substances. No interventions improved detection of advanced adenomas, and only narrow-band imaging improved detection of serrated lesions (odds ratio, 2.94; 95% credible interval, 1.46-6.25). CONCLUSIONS Several interventions are effective in improving adenoma detection and overall colonoscopy quality, many of which are cost-free. These results can inform endoscopists, unit managers, and endoscopy societies on relative efficacies.

Abstract
Background and study aims The Paris classification characterizes the morphology of superficial gastrointestinal tract neoplasms. This system has been shown to predict the risk of submucosal invasion in certain subtypes of lesions. There is limited data that assesses its agreement amongst endoscopists. We performed a systematic review to summarize the available literature on the interobserver reliability (IOR) of the Paris classification. Methods We conducted a search through December 2020 for studies reporting IOR of the Paris classification. Studies were included if they quantitatively evaluated the IOR of the Paris classification with at least five participating endoscopists. Two authors independently screened studies and abstracted data using an a priori-designed data collection form. Evaluation of study quality and risk of bias was performed using an adapted version of the Guidelines for Reporting Reliability and Agreement Studies. Results Of the 1,541 studies retrieved, 5 were included in the review. All studies were observational cohort studies published between 2014 and 2020. The IOR of the Paris classification was moderate amongst all four studies evaluating colorectal neoplasms (range, κ = 0.42 to κ = 0.54) and substantial in one study that evaluated gastric neoplasms (κw = 0.65). An educational intervention was conducted by three studies with variable methodology and no significant change in IOR. Conclusions IOR of the Paris classification is moderate for superficial colonic neoplasms. Further study is needed to determine the reliability of this system for superficial gastric lesions. Standardized training programs are required to investigate the impact of educational intervention on the Paris classification amongst endoscopists.

Abstract
BACKGROUND : Assessment of competence in endoscopic retrograde cholangiopancreatography (ERCP) is critical for supporting learning and documenting attainment of skill. Validity evidence supporting ERCP observational assessment tools has not been systematically evaluated. METHODS : We conducted a systematic search using electronic databases and hand-searching from inception until August 2021 for studies evaluating observational assessment tools of ERCP performance. We used a unified validity framework to characterize validity evidence from five sources: content, response process, internal structure, relations to other variables, and consequences. Each domain was assigned a score of 0-3 (maximum score 15). We assessed educational utility and methodological quality using the Accreditation Council for Graduate Medical Education framework and the Medical Education Research Quality Instrument, respectively. RESULTS : From 2769 records, we included 17 studies evaluating 7 assessment tools. Five tools were studied for clinical ERCP, one for simulated ERCP, and one for simulated and clinical ERCP. Validity evidence scores ranged from 2 to 12. The Bethesda ERCP Skills Assessment Tool (BESAT), ERCP Direct Observation of Procedural Skills Tool (ERCP DOPS), and The Endoscopic Ultrasound (EUS) and ERCP Skills Assessment Tool (TEESAT) had the strongest validity evidence, with scores of 10, 12, and 11, respectively. Regarding educational utility, most tools were easy to use and interpret, and required minimal additional resources. Overall methodological quality (maximum score 13.5) was strong, with scores ranging from 10 to 12.5. CONCLUSIONS : The BESAT, ERCP DOPS, and TEESAT had strong validity evidence compared with other assessments. Integrating tools into training may help drive learners' development and support competency decision making.

Abstract
PURPOSE Self-assessment of a physician's performance in both procedure and non-procedural activities can be used to identify their deficiencies to allow for appropriate corrective measures. Physicians are inaccurate in their self-assessments, which may compromise opportunities for self- development. To improve this accuracy, video-based interventions of physicians watching their own performance, an experts' performance or both, have been proposed to inform their self-assessment. We conducted a systematic review of the effectiveness of video-based interventions targeting improved self-assessment accuracy among physicians. MATERIALS AND METHODS The authors performed a systematic search of MEDLINE, Embase, EBM reviews, and Scopus databases from inception to August 23, 2022, using combinations of terms for "self-assessment", "video-recording", and "physician". Eligible studies were empirical investigations assessing the effect of video-based interventions on physicians' self-assessment accuracy with a comparison of self-assessment accuracy pre- and post- video intervention. We defined self-assessment accuracy as a "direct comparison between an external evaluator and self-assessment that was quantified using formal statistical analysis". Two reviewers independently screened records, extracted data, assessed risk of bias, and evaluated quality of evidence. A narrative synthesis was conducted, as variable outcomes precluded a meta-analysis. RESULTS A total of 2,376 papers were initially retrieved. Of these, 22 papers were selected for full-text review; a final 9 studies met inclusion criteria for data extraction. Across studies, 240 participants from 5 specialties were represented. Video-based interventions included self-video review (8/9), benchmark video review (3/9), and/or a combination of both types (1/9). Five out of nine studies reported that participants had inaccurate self-assessment at baseline. After the intervention, 5 of 9 studies found a statistically significant improvement in self-assessment accuracy. CONCLUSIONS Overall, current data suggests video-based interventions can improve self-assessment accuracy. Benchmark video review may enable physicians to improve self-assessment accuracy, especially for those with limited experience performing a particular clinical skill. In contrast, self-video review may be able to provide improvement in self-assessment accuracy for more experience physicians. Future research should use standardized methods of comparison for self-assessment accuracy, such as the Bland-Altman analysis, to facilitate meta-analytic summation.

Abstract
Background Credentialing in GI endoscopy is not a universally standardized process. National guidelines may provide a framework for local training, however in certain settings, training committees set minimal competency requirements that must be met before a clinician can be accredited to practice independently. There is a paucity of literature assessing the inter-societal and geographic variability in guidelines and training requirements in endoscopy. Purpose To systematically review the available credentialing guidelines proposed by different GI endoscopy societies and affiliated training committees internationally. Method We conducted a systematic review according to the PRISMA guidelines. A comprehensive literature search was performed for credentialing guidelines for GI endoscopy from inception until January 2022. Two reviewers screened and one reviewer abstracted data using a pre-defined data collection form. Result(s) From the 653 records obtained from our search, 20 credentialing guidelines from 12 different GI societies were ultimately included in the review. These guidelines encompassed the following procedures and outlined the following key-performance indicators; a) Colonoscopy: the recommended minimum number of procedures performed ranged from 150-275 with a minimum cecal intubation and adenoma detection rate of 85-90% and 20-30% respectively; b) EGD: the minimum number of procedures prior to credentialing ranged from 130-1000, the minimum duodenal intubation rate ranged from 95-100%, and the range for minimum number of upper GI bleeds managed was 20-45 (in addition to other procedural KPIs); c) ERCP: the recommended minimum number of procedures prior to credentialing ranged from 100-300 cases with a minimum selective duct cannulation rate of 80-90%. Guidelines for flexible sigmoidoscopy, EUS and capsule endoscopy were also obtained. Image ![]()
Conclusion(s) There is a general concordance amongst the various international GI societies with regards to minimum procedural volume and performance in key procedural tasks prior to credentialing, however the use of validated education assessment tools was lacking in the majority of guidelines. Additional KPI’s need to be explored for less routinely performed procedures such as EUS and capsule endoscopy.

Abstract
Background Polypectomy is an essential skill for endoscopists to acquire. As polyps are encountered ad hoc during colonoscopies, exposure to polypectomy in clinical training may vary. There is a need to deliver a curriculum that standardizes exposure to polypectomy while remaining cost-effective for endoscopy programs worldwide. Purpose To develop low-cost simulated polyps that can be incorporated into endoscopic training programs, and to evaluate their perceived realism and useability for polypectomy training. Method We designed 3D molds based on the Paris classification, a validated rubric for polyp morphology. The polyps are depicted in Figure 1. Using low-cost materials, we created gel-based polyps compatible with physical colonic simulators. Current versions of the polyps were finalized based on visual realism and durability. Expert (performed >1000 procedures) and novice (<25 procedures) endoscopists were invited to perform simulated polypectomies and evaluate the realism of the polyps. Using a 7-point Likert scale (“strongly disagree” to “strongly agree”), we administered a survey adapted from the Direct Observed Polypectomy Skills (DOPyS) checklist to evaluate the polyps on practicality of design and useability for training. Additionally, the simulator’s resemblance to human polypectomy was assessed through a scale with 1 indicating “low resemblance” and 7 indicating “high resemblance”. The ease of identifying morphology was also evaluated, with 1 indicating “difficult” and 7 indicating “easy”. Result(s) The survey was completed by 11 expert endoscopists and 10 novices. The median score submitted by experts on the polyps’ useability in training the technique for mobilization of the polyp was 7 (IQR 6-7). Experts rated the simulator’s practicality in teaching cold snare or electrocautery techniques with a median score of 6 (IQR 6-7). Lastly, the ability of the simulator to develop skills in identifying and treating the residual polyp was assessed by expert endoscopists, giving it a median score of 6 (IQR 6-7). The simulators were tested on similarity to human polypectomy, with the median score of expert groups being 5 (IQR 5-6), and novice groups being 6 (IQR 6-6). Both groups were asked to rate if morphology could be identified using the simulator; the median score of expert groups being 6 (IQR 6-7), and 6.5 for novice endoscopists (IQR 5-7). Image ![]()
Conclusion(s) The development of simulated polyps with differing morphologies using low-cost and common materials with high realism is feasible. These polyps may potentially be integrated into different endoscopic training programs. Please acknowledge all funding agencies by checking the applicable boxes below None Disclosure of Interest A.

Abstract
Background Assessment of competence in endoscopic retrograde cholangiopancreatography (ERCP) is essential to ensure trainees possess the skills needed for independent practice. Traditionally, ERCP training has used the apprenticeship model, whereby novices learn skills under the supervision of an expert. A growing focus on procedural quality, however, has supported the implementation of competency-based medical education models which require documentation of a trainee’s competence for independent practice. Observational assessment tools with strong evidence of validity are critical to this process. Validity evidence supporting ERCP observational assessment tools has not been systematically evaluated. Purpose To conduct a systematic review of ERCP assessment tools and identify tools with strong evidence of validity using a unified validity evidence framework Method We conducted a systematic search using electronic databases and hand-searching from inception until August 2021 for studies evaluating observational assessment tools of ERCP performance. We used a unified validity framework to characterize validity evidence from five sources: content, response process, internal structure, relations to other variables, and consequences. Each domain was assigned a score of 0-3 (maximum score 15). We assessed educational utility and methodological quality using the Accreditation Council for Graduate Medical Education framework and the Medical Education Research Quality Instrument, respectively. Result(s) From 2769 records, we included 17 studies evaluating 7 assessment tools. Five tools were studied for clinical ERCP, one on simulated ERCP, and one on simulated and clinical ERCP. Validity evidence scores ranged from 2-12. The Bethesda ERCP Skills Assessment Tool (BESAT), ERCP Direct Observation of Procedural Skills Tool (ERCP DOPS), and The Endoscopic Ultrasound (EUS) and ERCP Skills Assessment Tool (TEESAT) had the strongest validity evidence with scores of 10, 12, and 11, respectively. Regarding educational utility, most tools were easy to use and interpret, and required minimal additional resources. Overall methodological quality was strong, with scores ranging from 10-12.5 (maximum 13.5). Conclusion(s) The BESAT, ERCP DOPS, and TEESAT have strong validity evidence compared to other assessments. Integrating tools into training may help drive learners’ development and support competency decision-making.

Abstract
Background and study aims Credentialing, the process through which an institution assesses and validates an endoscopist's qualifications to independently perform a procedure, can vary by region and country. Little is known about these inter-societal and geographic differences. We aimed to systematically characterize credentialing recommendations and requirements worldwide. Methods We conducted a systematic review of credentialing practices among gastrointestinal and endoscopy societies worldwide. An electronic search as well as hand-search of World Endoscopy Organization members' websites was performed for credentialing documents. Abstracts were screened in duplicate and independently. Data were collected on procedures included in each document (e. g. colonoscopy, ERCP) and types of credentialing statements (procedural volume, key performance indicators (KPIs), and competency assessments). The primary objective was to qualitatively describe and compare the available credentialing recommendations and requirements from the included studies. Descriptive statistics were used to summarize data when appropriate. Results We screened 653 records and included 20 credentialing documents from 12 societies. Guidelines most commonly included credentialing statements for colonoscopy, esophagogastroduodenoscopy (EGD), and ERCP. For colonoscopy, minimum procedural volumes ranged from 150 to 275 and adenoma detection rate (ADR) from 20 % to 30%. For EGD, minimum procedural volumes ranged from 130 to 1000, and duodenal intubation rate of 95 % to 100%. For ERCP, minimum procedural volumes ranged from 100 to 300 with selective duct cannulation success rate of 80 % to 90 %. Guidelines also reported on flexible sigmoidoscopy, capsule endoscopy, and endoscopic ultrasound. Conclusions While some metrics such as ADR were relatively consistent among societies, there was substantial variation among societies with respect to procedural volume and KPI statements.

Abstract
INTRODUCTION Colonoscopy quality can vary depending on endoscopist-related factors. Quality indicators, such as adenoma detection rate (ADR), have been adopted to reduce variations in care. Several interventions aim to improve ADR, but these fall into several domains that have traditionally been difficult to compare. We will conduct a systematic review and network meta-analysis of randomised controlled trials evaluating the efficacies of interventions to improve colonoscopy quality and report our findings according to clinically relevant interventional domains. METHODS AND ANALYSIS We will search MEDLINE (Ovid), PubMed, EMBASE, CINAHL, Web of Science, Scopus and Evidence-Based Medicine from inception to September 2022. Four reviewers will screen for eligibility and abstract data in parallel, with two accordant entries establishing agreement and with any discrepancies resolved by consensus. The primary outcome will be ADR. Two authors will independently conduct risk of bias assessments. The analyses of the network will be conducted under a Bayesian random-effects model using Markov-chain Monte-Carlo simulation, with 10 000 burn-ins and 100 000 iterations. We will calculate the ORs and corresponding 95% credible intervals of network estimates with a consistency model. We will report the impact of specific interventions within each domain against standard colonoscopy. We will perform a Bayesian random-effects pairwise meta-analysis to assess heterogeneity based on the I2 statistic. We will assess the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework for network meta-analyses. ETHICS AND DISSEMINATION Our study does not require research ethics approval given the lack of patient-specific data being collected. The results will be disseminated at national and international gastroenterology conferences and peer-reviewed journals. PROSPERO REGISTRATION NUMBER CRD42021291814.

Abstract
Introduction
Pericardial effusion (PE) in patients with infective endocarditis (IE) has been shown to be an independent risk factor for severe complications, however no significant association with mortality has been established. Our study aims to study the significance of pericardial effusion in patients with IE.
Methods
We performed a retrospective analysis using the United States National Inpatient Sample (NIS) database to identify all the hospital admissions with IE using ICD 10 codes and divided them into two groups based on the presence of PE. The outcomes of interest were in-hospital mortality, in-hospital complications, need for cardiac surgery, and length of stay (LOS).
Results
A total of 381,300 patients were hospitalized from 2016 to 2019 with IE, of whom 10,370 developed PE. Mean age of patients in the PE group was 51 years and in non-PE group was 61 years with males and Caucasian race being predominant in both groups. PE group had higher rates of in-hospital death (12.7% vs 9%, P≤0.001) and longer in-hospital stay (12 days vs 7 days, P≤0.001) compared to non-PE group. The rates of cardiac surgery were higher in PE group (26.1% vs 8.4%, P≤0.001). The rates of heart failure, heart block, renal failure, cardiogenic shock, and embolic stroke were higher in PE group [Table 1].
Conclusion
Our study shows that presence of PE in patients with IE is a predictor for in-hospital mortality, length of stay, and need for cardiac surgery. Also, these patients are at higher risk for heart failure, heart block, cardiogenic shock and embolic stroke.

Abstract
Background and study aims Endoscopists are at high risk of musculoskeletal pain and injuries (MSPI). Recently, ergonomics has emerged as an area of interest to reduce and prevent the incidence of MSPI in endoscopy. The aim of this systematic review was to determine educational interventions using ergonomic strategies that target reduction of endoscopist MSPI from gastrointestinal endoscopy. Methods In December 2020, we conducted a systematic search in MEDLINE, EMBASE, PsycINFO, Web of Science, Scopus, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews for articles published from inception to December 16, 2020. Studies were included if they investigated educational interventions aimed at changing knowledge and/or behaviors related to ergonomics in gastrointestinal endoscopy. After screening and full-text review, we extracted data on study design, participants, type of training, and assessment of primary outcomes. We evaluated study quality with the Medical Education Research Study Quality Instrument (MERSQI). Results Of the initial 575 records identified in the search, five met inclusion criteria for qualitative synthesis. We found that most studies (n = 4/5, 80 %) were single-arm interventional studies that were conducted in simulated and/or clinical settings. The most common types of interventions were didactic sessions and/or videos (n = 4/5, 80%). Two (40 %) studies used both standardized assessment studies and formal statistical analyses. The mean MERSQI score was 9.7. Conclusions There is emerging literature demonstrating the effectiveness of interventions to improve ergonomics in gastrointestinal endoscopy.

Abstract
RATIONALE Since the beginning of the COVID-19 pandemic, many hospitals have reduced in-hospital visitation. In these situations, virtual communication tools have helped maintain interaction between parties. The Frontline Connect program was designed to address communication and patient care challenges by providing data-enabled devices to clinical staff in hospitals. OBJECTIVE This study aimed to identify areas of improvement for the Frontline Connect program by: (a) evaluating communication needs, user experience, and program satisfaction; and (b) identifying potential barriers to device access or use. METHODS We administered pre-implementation needs assessment, post-use, and exit surveys to healthcare staff at a pilot hospital site in Ontario. Recruitment was through email lists and site champions using convenience sampling. We descriptively analysed survey responses and compared the initial need statements to post-implementation use-cases identified by users. RESULTS We received 139 needs assessments, 31 user experience assessments, and 47 exit survey responses. Most device use occurred in the emergency department and intensive care units and was facilitated by social workers, nurses, and physicians to connect patients, families, and care providers. Pre-implementation concerns were related to infection control, data security, and device privacy. In the exit survey, these were replaced by other concerns including Internet connectivity and time-intensiveness. Device utility and ease-of-use were rated 9.7/10 and 9.6/10 respectively in the user experience survey, though overall experience was rated 7.2/10 in the exit survey. Overall, respondents viewed the devices as useful and we agree with participants who suggested increased program promotion and training would likely improve adoption. CONCLUSIONS We found that our virtual technology program for facilitating communication was positively perceived. Survey feedback indicates that a rapid rollout in response to urgent pandemic-related needs was feasible, though program logistics could be improved. The current work supports the need to improve, standardize, and sustain virtual communication programs in hospitals.

Abstract
Abstract
Study question
Can a novel protocol for endometrial preparation- NC/PR-FET, lead to better pregnancy outcomes than artificial cycle (AC)-FET, with similar ease of cycle monitoring and scheduling?
Summary answer
NC/PR-FET protocol gave comparable clinical pregnancy rates (CPR), significantly less early miscarriage rates (MR) and significantly more live birth rates (LBR) compared to AC-FET protocol.
What is known already
AC-FET is the most common protocol for endometrial preparation due to flexibility, easy monitoring, and high pregnancy rates albeit with evidence of higher obstetrical risks e.g., miscarriage, pre-eclampsia versus NC-FET. This risk could be due to suboptimal hormonal administration in AC-FET leading to impaired endometrial maturation, predecidualization, and altered endometrial function. Studies indicate, estradiol may have a stronger negative effect(versus progesterone) on the endometrial transcriptome. Hence, we studied a novel protocol with NC-estrogen (but with progesterone similar to AC-FET), for better endometrial maturation, predecidualization along with simple monitoring and flexible ET scheduling. Previously, a proof-of-concept case-series has been reported.
Study design, size, duration
The prospective comparative study was conducted at a tertiary center (Jan2019-Dec2021) with 126 patients (both autologous [AO] and donor oocytes [DO]):79 (AC-FET) and 47 (NC/PR-FET) with similar ICSI, vitrification, ET protocols. 2 or 3 Grade A cleavage stage embryos were transferred. CPR, implantation rates(IR), early MR (≤13 weeks, miscarriages/clinical pregnancies) and LBR (≥28 weeks, LBs/ETs) were compared. Serum progesterone was studied on day 5 post-ET. Antenatal care and most deliveries were at the same institute.
Participants/materials, setting, methods
Patients were non-smokers with normal hysteroscopy. In AC-FET, oral estradiol (6-8mg) was initiated from day 1-2 (for 10-17 days). In both groups, when endometrium ≥7mm and S.progesterone<1ng/ml, intramuscular progesterone was initiated(daily till day 4 post-ET, then every 3rd day till week 8). ET was scheduled on day 4 of intramuscular progesterone, and concurrently, vaginal progesterone was added (till week 10). Chi-square, t-tests, and multiple regression was used for statistical analysis and 2-tailed P <.05 indicated statistical significance.
Main results and the role of chance
Mean age and BMI were comparable in NC/PR-FET and AC-FET groups: 34.48±4.69 years vs. 33.58 ± 5.62 years (P =.35) and 26.27 ± 3.62 kg/m2 vs. 27.34 ± 4.61kg/m2 (P =.18) respectively. Similarly, the source of oocytes (%AO) and % singletons were also comparable in NC/PR-FET and AC-FET groups: 57.4% vs. 46.8% (P = .25), and 78.1% vs. 75% (P= .75) respectively. There were 3 ectopic pregnancies overall. The CPRs and IRs were comparable: 68.09% (NC/PR-FET) vs. 60.76% (AC-FET) (P=.41) and 32.30% (NC/PR-FET) vs. 28.96% (AC-FET) (P=.45) respectively.
The early MR was significantly more in AC-FET vs. NC/PR-FET: 29.17% vs. 6.25% (P =.012). Consequently, LBRs were significantly more in NC/PR-FET vs. AC-FET: 59.57% vs. 39.24% (P =.028). After adjusting for age, BMI, AO/DO, this difference remained significant (AOR 2.66; 95% CI 1.21-5.81; P =.014)
Mean serum progesterone was comparable in all patients in both groups: 38.50 ± 13.6ng/ml (NC/PR-FET) vs. 40.98 ± 28.64 ng/ml (AC-FET) (P =.57). Serum progesterone levels were also comparable in patients who were pregnant in both groups: 38.51 ± 14.79 (NC/PR-FET) vs. 42.25 ± 32.63 (AC-FET) (P =.53).Also, in the AC-FET group serum progesterone was comparable in patients who aborted,44.23 ± 31.60 vs. those who didn’t, 41.48 ± 33.44 (P =.79).
Limitations, reasons for caution
This was a single center study. Due to limited sample size, we could not control for many potential confounders (e.g., multiple pregnancies). For the same reason, we could not compare obstetrical risks as a study outcome.
Wider implications of the findings
This study shows significantly better pregnancy outcomes with a novel NC/PR-FET protocol vs. AC-FET. This needs to be validated in larger studies. Since suboptimal hormone administration in AC-FET could be causal factor for pre-eclampsia, larger studies can test if the NC/PR-FET protocol can lead to better obstetrical outcomes.

Abstract
BACKGROUND AND AIM Changes to endoscopy service availability during the COVID-19 pandemic may have affected management of upper gastrointestinal bleeding (UGIB). The aim of this study was to describe the impact of the pandemic on UGIB outcomes in the Toronto area in Canada. METHODS We described all adults admitted to general medicine wards or intensive care units at six hospitals in Toronto and Mississauga, Canada, with UGIB during the first wave of the COVID-19 pandemic (March 1 to June 30, 2020) and compared them with a historical cohort (March 1 to June 30, 2018 and 2019). We compared clinical outcomes (in-hospital mortality, length of stay, 30-day readmission, intensive care utilization, receipt of endoscopy, persistent bleeding, receipt of second endoscopy, and need for angiographic or surgical intervention) using multivariable regression models, controlling for demographics, comorbidities, and severity of clinical presentation. RESULTS There were 82.5 and 215.5 admissions per month for UGIB during the COVID-19 and control periods, respectively. There were no baseline differences between groups for demographic characteristics, comorbidities, or severity of bleeding. Patients in the COVID-19 group did not have significantly different unadjusted (3.9% vs 4.2%, P = 0.983) or adjusted mortality (adjusted odds ratio [OR] = 0.64, 95% confidence interval [CI] = 0.25-1.48, P = 0.322). Patients in COVID-19 group were less likely to receive endoscopy for UGIB in the unadjusted (61.8% vs 71.0%, P = 0.003) and adjusted (adjusted OR = 0.64, 95% CI = 0.49-0.84, P < 0.01) models. There were no differences between groups for other secondary outcomes. CONCLUSIONS While patients admitted for UGIB during the first wave of the pandemic were less likely to receive endoscopy, this had no impact on mortality or any secondary outcomes.

Abstract
Background Recommendations in clinical practice guidelines (CPGs) may be reversed when evidence emerges to show they are futile or unsafe. In this study, we identified and characterized recommendation reversals in gastroenterology CPGs. Methods We searched CPGs published by 20 gastroenterology societies from January 1990 to December 2019. We included guidelines which had at least two iterations of the same topic. We defined reversals as when (a) the more recent iteration of a CPG recommends against a specific practice that was previously recommend in an earlier iteration of a CPG from the same body, and (b) the recommendation in the previous iteration of the CPG is not replaced by a new diagnostic or therapeutic recommendation in the more recent iteration of the CPG. The primary outcome was the number of recommendation reversals. Secondary outcomes included the strength of recommendations and quality of evidence cited for reversals. Results Twenty societies published 1022 CPGs from 1990 to 2019. Our sample for analysis included 129 unique CPGs. There were 11 recommendation reversals from 10 guidelines. New evidence was presented for 10 recommendation reversals. Meta-analyses were cited for two reversals, and randomized controlled trials (RCTs) for seven reversals. Recommendations were stronger after the reversal for three cases, weaker in two cases, and of similar strength in three cases. We were unable to compare recommendation strengths for three reversals. Conclusion Recommendation reversals in gastroenterology CPGs are uncommon but highlight low value or harmful practices.

Abstract
Background Nontechnical skills (NTS), which involve an individual’s cognitive, attitudinal, and social skills that supplement task expertise, are an essential component in the practice of gastrointestinal endoscopy. There is a growing body of literature that highlights the association between these skills and patient outcomes. To date, however, these skills have not been adequately defined within the context of gastrointestinal endoscopy. Aims To define the domain and corresponding characteristics of NTS in GI endoscopy. Methods We conducted a qualitative study at a tertiary-care academic center in Toronto, Ontario. Specifically, we held four focus groups with physician endoscopists, nurses who work in an endoscopy unit, and patients who have had previous endoscopies, in order to ascertain their input on the role of NTS in gastrointestinal endoscopy. The three groups were interviewed independently and there was one focus group of both physicians and nurses that was used for validation of our initial thematic framework. Data from the focus groups was collected using a combination of field notes and discussion transcriptions. Three authors independently generated codes from these data. Using these codes, a thematic network analysis was used to identify emerging themes. The primary outcome of this study was the development of a cohesive thematic network of NTS in endoscopy, including their characteristics and examples. Results The four focus groups included a total of 34 participants, including 15 physician endoscopists, 15 nurses, and 4 patients. Using thematic network analysis, we identified six dimensions of NTS using the first three focus groups: communication; professionalism; teamwork; leadership; decision-making; and situational awareness. Additional topics related to the practice and evaluation of NTS were identified. In particular, there is a degree of subjectivity in the appraisal of NTS due to the nuances among individual practice, aside from egregious errors of NTS (e.g. unprofessional behaviours). The use of video recordings was suggested as a way to capture signs of good NTS, such as appropriate levels of calmness during procedures and attention to patient comfort. Finally, patient involvement can be useful for evaluating communication and professionalism based on patient comprehension and the nature of the therapeutic relationship. Conclusions Our findings provide the first cohesive framework of NTS in gastrointestinal endoscopy that is anchored in real world experiences with relevant stakeholders – physicians, nurses, and patients. Future research should consolidate these findings into an assessment tool for NTS in order to evaluate and provide feedback to endoscopists who are both in training and in practice.

Abstract
Abstract
Background
Clinical Practice Guidelines (CPGs) are integral during a pandemic, offering guidance to clinicians through uncertainty. Existing literature has established that the need for rapid publication of CPGs during previous infectious disease outbreaks resulted in less rigorous guidelines. CPGs were rapidly developed since the onset of the pandemic in December 2019, providing guidance in gastrointestinal (GI) endoscopy, an area where COVID-19 may pose risk of transmission.
Aims
To evaluate the quality of GI endoscopy guidelines developed during the COVID-19 pandemic and to compare these with (a) endoscopy CPGs developed prior to the pandemic; (b) CPGs for other endoscopic topics unrelated to COVID-19; and, (c) non-endoscopic CPGs published during the pandemic.
Methods
We systematically searched Medline, Embase and Scopus for CPGs published by GI societies from January 1, 2018 to December 31, 2020. A grey literature search was conducted. Two authors screened full-texts. In this interim analysis, CPGs were grouped based on publication year: before 2020, or 2020. Endoscopy CPGs published in 2020 were categorized as COVID or non-COVID related. Two authors independently assessed the CPGs using the AGREE II tool, consisting of six domains for evaluating guidelines. A domain score of 60 was set as a threshold to indicate good quality.
Results
There were 70 endoscopy guidelines and 27 CPGs focused on other GI topics. The mean overall scores were 69% (±12%) for endoscopy CPGs published before 2020 (n=28), and 51% (±23%) for CPGs published in 2020 (n=42). For individual AGREE II domains, mean scores for pre-2020 CPGs ranged from 33.11 (±17.39) in Applicability to 81.55 (±10.37) in Clarity of Presentation. For CPGs published during COVID-19, mean domain scores ranged from 34.18 (±10.52) in Applicability to 75.26 (±13.85) in Clarity of Presentation. 21 of 42 CPGs published in 2020 were related to COVID. Mean overall scores were 35% (±20%) for COVID-related CPGs and 67% (±13%) for non-COVID-19 CPGs. For COVID-19 CPGs, scores ranged from 27.88 (±20.31) in Rigour of Development to 69.58 (±10.81) in Scope and Purpose. For non-COVID CPGs, the scores ranged from 37.30 (±8.93) in Applicability to 84.52 (±5.93) in Clarity of Presentation.
Conclusions
The difference in overall scores between COVID-19 endoscopy CPGs and non-COVID endoscopy CPGs may suggest that the urgency to disseminate COVID-19 information decreased CPG quality or completeness of reporting. This interim analysis is limited by the lack of distinction between peer-reviewed CPGs and non-peer reviewed recommendations. Given the importance of CPGs in clinical decision making, it is important to ensure that the rapid development of guidelines does not compromise quality and rigour.

Abstract
Background Patient advocacy organizations (PAOs) are not-for-profit organizations that aim to support families and individuals afflicted by illnesses. PAOs play a significant role in guiding health policy, providing education to patients, lobbying, and supporting research. Previous studies have demonstrated that PAOs may receive financial payments from pharmaceutical and medical device manufacturers. This may create a risk of conflict of interest. Aims To assess the prevalence and transparency of financial donations from industry to gastrointestinal patient advocacy groups based in the United States (US). Methods We conducted a cross-sectional study to determine the prevalence of industry donations to PAOs. Data was extracted from the Kaiser Health News (KHN) Database, a database that tracked payments from pharmaceutical companies to PAOs in 2015. After an initial list of 1215 PAOs was obtained from the database, authors extracted the annual revenues, websites and mission statements for each PAO. Authors individually screened each organization’s mission statement and website to determine whether their primary scope of focus included gastroenterology. A final list of 11 PAOs with annual revenues surpassing $500,000 USD was included for descriptive analysis. From this list, the annual reports and websites of each group were reviewed to determine the extent of transparency of PAOs disclosing financial relationships with industry sponsors. The primary outcome of our study was the total amount of funding that each PAO received from pharmaceutical companies. The secondary outcome was the self-reported amount of funding stated on each PAO’s website and annual report. Results From our analysis of 11 PAOs, 9 (81%) organizations received payments from pharmaceutical companies. The median dollar value of donations received was $31,052 USD (IQR=$25 to $302,550). The total dollar value of donations received was $4,059,433 USD. Across the 9 PAOs that received donations, 5 (56%) organizations disclosed a financial relationship with a pharmaceutical company on their website and 2 (22%) disclosed the value of industry donations within a range. No group specified an exact amount of funding received. Conclusions Our results demonstrate that a majority of US based gastrointestinal PAOs receive funding from pharmaceutical companies. Furthermore, our results show that many PAOs that receive industry funding do not disclose this amount on their website or annual reports. Given their role in providing patient centered support, it is important for PAOs to disclose financial relationships with industry so as to not produce a conflict of interest. Funding Agencies None

Abstract
Background Propensity score matching (PSM), a statistical technique that estimates a treatment effect by accounting for predictor covariates, has been used to evaluate biologics for inflammatory bowel disease (IBD). Financial conflicts of interest are prevalent in the marketing of biologic medications. It is unclear whether this burden of conflicts is present among authors of PSM studies comparing IBD biologics and biosimilars. Objective This study was aimed to determine the prevalence of financial conflicts of interest among authors of PSM studies evaluating IBD biologics and biosimilars. Methods We conducted a systematic search for PSM studies comparing biologics and biosimilars in IBD treatment. We identified 21 eligible studies. Two independent authors extracted self-declared conflicts from the disclosures section. Each participating author was searched on the Centers for Medicare & Medicaid Services Open Payments to identify payment amounts and undisclosed conflicts. Primary outcome was the prevalence of author conflicts. Secondary analyses assessed for an association between conflict prevalence and reporting of positive outcomes. Results Among 283 authors, conflicts were present among 41.0% (116 of 283). Twenty-three per cent (27 of 116) of author conflicts involved undisclosed payments. Studies with positive outcomes were significantly more likely to include conflicted authors than neutral studies (relative risk = 2.34, 95% confidence interval: 1.71 to 3.21, P < 0.001). Conclusions Overall, we found a high burden of undisclosed conflicts among authors of PSM studies comparing IBD biologics and biosimilars. Given the importance of PSM studies as a means for biologic comparison and the potential for undue industry influence from these payments, authors should ensure greater transparency with reporting of industry relationships.

Abstract
Background and study aims Colonoscopy completion reduces post-colonoscopy colorectal cancer. As a result, there have been attempts at implementing artificial intelligence to automate the detection of the appendiceal orifice (AO) for quality assurance. However, the utilization of these algorithms has not been demonstrated in suboptimal conditions, including variable bowel preparation. We present an automated computer-assisted method using a deep convolutional neural network to detect the AO irrespective of bowel preparation. Methods A total of 13,222 images (6,663 AO and 1,322 non-AO) were extracted from 35 colonoscopy videos recorded between 2015 and 2018. The images were labelled with Boston Bowel Preparation Scale scores. A total of 11,900 images were used for training/validation and 1,322 for testing. We developed a convolutional neural network (CNN) with a DenseNet architecture pre-trained on ImageNet as a feature extractor on our data and trained a classifier uniquely tailored for identification of AO and non-AO images using binary cross entropy loss. Results The deep convolutional neural network was able to correctly classify the AO and non-AO images with an accuracy of 94 %. The area under the receiver operating curve of this neural network was 0.98. The sensitivity, specificity, positive predictive value, and negative predictive value of the algorithm were 0.96, 0.92, 0.92 and 0.96, respectively. AO detection was > 95 % regardless of BBPS scores, while non-AO detection improved from BBPS 1 score (83.95 %) to BBPS 3 score (98.28 %). Conclusions A deep convolutional neural network was created demonstrating excellent discrimination between AO from non-AO images despite variable bowel preparation. This algorithm will require further testing to ascertain its effectiveness in real-time colonoscopy.

Abstract
Mating has profound physiological and behavioural consequences for female insects. During copulation, female insects typically receive not only sperm, but a complex ejaculate containing hundreds of proteins and other molecules from male reproductive tissues, primarily the reproductive accessory glands. The post-mating phenotypes affected by male accessory gland (MAG) proteins include egg development, attraction to oviposition hosts, mating, attractiveness, sperm storage, feeding and lifespan. In the Mexican fruit fly, Anastrepha ludens, mating increases egg production and the latency to remating. However, previous studies have not found a clear relationship between injection of MAG products and oviposition or remating inhibition in this species. We used RNA-seq to study gene expression in mated, unmated and MAG-injected females to understand the potential mating- and MAG-regulated genes and pathways in A. ludens. Both mating and MAG-injection regulated transcripts and pathways related to egg development. Other transcripts regulated by mating included those with orthologs predicted to be involved in immune response, musculature and chemosensory perception, whereas those regulated by MAG-injection were predicted to be involved in translational control, sugar regulation, diet detoxification and lifespan determination. These results suggest new phenotypes that may be influenced by seminal fluid molecules in A. ludens. Understanding these influences is critical for developing novel tools to manage A. ludens.

Abstract
BACKGROUND Since 2008, the Canadian Institutes of Health Research (CIHR) has mandated that studies it funds either in whole or in part are required to publish their results as open access (OA) within 12 months of publication using either online repositories and/or OA journals. Yet, there is evidence that authors are poorly compliant with this mandate. Specifically, there has been an apparent decrease in OA publication after 2015, which coincides with a change in the OA policy during the same year. One particular policy change that may have contributed to this decline was lifting the requirement that authors deposit their article in an OA repository immediately upon publication. We investigated the proportion of OA compliance of CIHR-funded studies in the period before and after the policy change of 2015 with manual confirmation of both CIHR funding and OA status. METHODS AND FINDINGS We identified CIHR-funded studies published between the years 2014 to 2017 using a comprehensive search in the Web of Science (WoS). We took a stratified random sample from all four years (i.e. 2014 to 2017), with 250 studies from each year. Two authors independently reviewed the final full-text publications retrieved from the journal web page to determine to confirm CIHR funding, as indicated in the acknowledgements or elsewhere in the paper. For each study, we also collected bibliometric data that included citation count and Altmetric attention score Statistical analyses were conducted using two-tailed Fisher's exact test with relative risk (RR). Among the 851 receiving CIHR funding published from 2014 to 2017, the percentage of CIHR-funded studies published as OA significantly decreased from 79.6% in 2014 to 70.3% in 2017 (RR = 0.88, 95% CI: 0.79-0.99, P = 0.028). When considering all four years, there was no significant difference in the percentage of CIHR-funded studies published as OA in both 2014 and 2015 compared to both 2016 and 2017 (RR = 0.97, 95% CI: 0.90-1.05, P = 0.493). Additionally, OA publications had significantly higher citation count (both in year of publication and in total) and higher attention scores (P<0.05). CONCLUSIONS Overall, we found that there was a significant decrease in the proportion of CIHR funded studies published as OA from 2014 compared to 2017, though this difference did not persist when comparing both 2014-2015 to 2016-2017. The primary limitation was the reliance of self-reported data from authors on CIHR funding status. We posit that this decrease may be attributable to CIHR's OA policy change in 2015. Further exploration is warranted to both validate these studies using a larger dataset and, if valid, investigate the effects of potential interventions to improve the OA compliance, such as use of a CIHR publication database, and reinstatement of a policy for authors to immediately submit their findings to OA repositories upon publication.

Abstract
Introduction The United States Food and Drug Administration (FDA) Gastrointestinal Drug Advisory Committee (GIDAC) is involved in gastrointestinal drug application reviews. Characteristics and conflicts of interest (COI) in GIDAC meetings are not well described. This study analyzed FDA GIDAC meetings and characteristics that predict recommendations. Methods In this cross-sectional study, all publicly available GIDAC meetings where proposed medications were voted on were included. Data were collected regarding indications, medication sponsor, primary efficacy studies, and voting member characteristics (e.g. committee membership, COI). Univariate analyses were conducted at per-meeting and per-vote levels to assess for predictors of committee recommendation and individual votes respectively. Results Thirty-four meetings with 476 individual votes from 1998–2018 were included. Twenty-three (68%) proposals were recommended for approval and 25 (74%) received FDA approval. Most proposals involved >1 primary study (n = 27, 79%). At least one voting member had a COI in 24 (71%) of 34 meetings. Twelve (35%) meetings had at least one sponsor COI. Among 476 individual votes, 74 (15.5%) involved a COI, with 33 (6.9%) sponsor COI. COI decreased significantly over time, with fewer COI in 2006–2010, 2011–2015, and 2016–2020 compared to 1996–2000 and 2001–2005 (p<0.01). There were no significant associations between pre-defined predictors, including COI, and committee level recommendations or individual votes (p>0.05 for all univariate analyses). Conclusions The GIDAC reviewed 34 proposals from 1998–2018. The majority were recommended for approval and later approved by the FDA, highlighting the GIDAC’s prominence in the regulatory process. COI are present among GIDAC panelists but decreasing over time and not associated with recommendations.

Abstract
Catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare inheritable fatal arrhythmogenic disorder, is difficult to diagnose and is a challenge to manage. A 21-years-old man presented with recurrent exertional syncope and complex multifocal ventricular ectopy. CPVT was diagnosed based on the clinical criteria, despite the absence of some classical findings. The patient underwent cardiac sympathetic denervation (CSD) after lifestyle modification and pharmacological management were ineffective. CSD proved to be effective. The patient did not have any exertional symptoms or recurrence of syncope at follow-up period of 1 year. The present case report adds to the growing evidence in favour of CSD for CPVT.

Abstract
Abstract
Background
Ghost-authorship involves the exclusion of individuals who have made substantial contributions to the article from the author byline. Previous studies have found that ghost-authorship is highly prevalent in industry-sponsored clinical trials. Its prevalence, however, has yet to be investigated in trials of biologics in the management of inflammatory bowel disease (IBD).
Aims
To determine the prevalence of ghost-authorship in IBD biologic industry-sponsored clinical randomized controlled trials (RCTs).
Methods
Biologic medications indicated for ulcerative colitis (UC) or for Crohn’s disease (CD) were identified using the Food and Drug Agency (FDA) database. We identified the clinical trials on clinicaltrials.gov corresponding to the data presented at the time of FDA approval. Specifically, we included the first publication for each trial to report study results for our analysis. Two authors independently identified the presence of ghost-authorship, which we defined as the exclusion on the author byline of the included RCT publication of any individuals who assisted in the writing of the trial manuscript and/or performed the data analyses.
Results
We identified a total of 28 relevant RCTs on biologic medications (10 for UC and 18 for CD), which were matched to 20 publications. We found ghost-authorship in 70% of publications (n=14); 40% (n=8) involved manuscript and protocol writing assistance from sponsor staff; 35% (n=7) involved medical writers from external companies; 15% (n=3) involved both sponsor staff and medical writers assisting in manuscript writing; and 20% (n=4) involved individuals performing data analysis or interpretation.
Conclusions
We found that ghost-authorship in industry-sponsored IBD biologic clinical trials has a moderately high prevalence, with the most common being manuscript or protocol writing assistance. A lack of transparency regarding sponsor-affiliated and/or external contributors may negatively affect the trust placed in medical research. One limitation is that data was only extracted from publications. Further evidence on ghost-authorship may be found in study protocols and registrations, which will be investigated in the future.

Abstract
Abstract
Background
Outcome switching is a well-described form of inconsistent reporting in randomized clinical trials (RCTs), wherein pre-specified primary and/or secondary outcomes are changed between trial registration and the publication of results without explanation. This is of particular concern, as the selective publication of results that are favorable will insert bias into the trial’s results and may cast doubt on the veracity of its findings. While it has been investigated in other disciplines, the prevalence of outcome switching has yet to be described among RCTs for inflammatory bowel disease (IBD).
Aims
To determine the prevalence of correctly reported pre-specified primary and secondary outcomes in published phase 3 interventional RCTs for IBD.
Methods
We identified all phase 3 interventional trials for IBD with published results using clinicaltrials.gov. We included all results with an associated publication that detailed the results of the trial. We excluded registrations if: only an abstract of the results was available; trial results were only published as a pooled analysis; multiple trial segments were reported collectively; or a publication of the results could not be identified through clinicaltrials.gov or a custom search.
Two reviewers extracted all pre-specified primary and secondary outcomes for each trial using the clinical trial registration page that was dated before the commencement of the trial. These outcomes were compared to the outcomes reported in the corresponding journal articles. Any discrepancies were noted, and additional outcomes were extracted.
Results
We identified a total of 88 phase 3 interventional RCTs for IBD, of which 57 were matched to independent publications of their results. All trials pre-specified a primary outcome, and 50 (87.7%) pre-specified secondary outcomes. 10 (17.5%) of trials did not report some or all primary outcomes, and 19 (33.3%) trials had a change or alteration to the primary outcome. Of the trials that pre-specified secondary outcomes, 16 (28.1%) did not report all pre-specified secondary outcomes. 49 (86.0%) trials added 6 (IQR: 2–8) unspecified secondary outcomes on average.
Conclusions
Many phase 3 interventional RCTs in IBD either did not report some or all primary outcomes, or altered the primary outcome. Trials routinely reported additional outcomes that were not pre-specified and failed to note that they were added post hoc. Based on these results, we recommend improvements in the reporting of pre-specified outcomes and higher fidelity in order to maintain confidence in trial results.

Abstract
Abstract
Background
Editorial self-publication refers to the practice wherein editors publish research in journals to which they serve as editorial board members. The International Committee of Medical Journal Editors (ICMJE) has detailed recommendations against the practice of self-publication. There is evidence to suggest that editorial board membership may influence the decision to publish academic papers, which may contribute to publication bias. Despite this, there have been few attempts to characterize this practice in gastroenterology journals.
Aims
To determine the prevalence of original gastroenterology research articles published by editorial board members in their own journal.
Methods
We conducted a cross-sectional study to determine the prevalence of editorial board members publishing within their own journals. A list of the top 25 highest impact factor gastroenterology journals was created through InCites Journal reports. Journals were screened to determine eligibility based on whether their primary focus included gastroenterology research and whether archives with the names and affiliations of editorial board members were available. 10 journals were selected based on these criteria. For each journal, we extracted all original research articles published in 2019 using Web of Science (Clarivate Analytics ©). Articles classified as editorial material, meeting abstracts, reviews, and clinical practice guidelines were excluded. We cross-referenced the affiliations of all authors found in each publication with affiliations of editors disclosed on the journal website. For each editorial board member, we determined the number of publications within their own journal.
Results
We identified 844 editorial board members in the 10 journals included. Overall, 337 (39.9%) of the editors had a publication in their own journal, of which, 152 (18.0%) had more than one publication. Across all journals, the median number of editors with self-publication is 27 (IQR=20.3–49.8). The median number of editors with more than one self-publication is 16 (IQR=10.0–25.3). In total, 507 (60.1%) of all editors had no publications within their respective journals.
Conclusions
Despite recommendations against this practice, our results show a high number of research publications authored by editorial board members. These results demonstrate a potential risk for publication bias. However, this study was limited by the inability to investigate beyond the prevalence of self-publication. Furthermore, the explicit implications of our results remain unclear. Further research is required to evaluate factors such as disclosures and the review process associated with increased rates of self-publication as well as its impact on publication bias.

Abstract
Background
The United States Food and Drug Administration (FDA) Gastrointestinal Drug Advisory Committee (GIDAC) is involved in gastrointestinal drug application reviews. Characteristics and conflicts of interest (COI) in GIDAC meetings are not well described.
Aims
To analyze FDA GIDAC meetings and characteristics that predict recommendations.
Methods
This was a cross-sectional study of all publicly available GIDAC meetings where proposed medications were voted on from 1998–2018. Data were collected on individual meetings and individual voting members at meetings. Predefined predictor variables included type of medication, medication sponsor, primary efficacy studies, and voting member characteristics (e.g. committee membership, COI). Univariate analyses were conducted at per-meeting and per-vote levels to assess for predictors of committee recommendation and individual votes respectively.
Results
Thirty-four meetings with 476 individual votes from 1998–2018 were included. Twenty-three (68%) proposals were recommended for approval and 25 (74%) received FDA approval. Most proposals involved >1 primary study (n=27, 79%). At least one voting member had a COI in 24 (71%) of 34 meetings. Twelve (35%) meetings had at least one sponsor COI. Among 476 individual votes, 74 (15.5%) involved a COI, with 33 (6.9%) sponsor COI. COI decreased significantly over time, with more COI in 1996–2000 and 2001–2005 compared to 2006–2010, 2011–2015, and 2016–2020 (p<0.01). There were no significant associations between pre-defined predictors, including COI, and committee level recommendations or individual votes (p>0.05 for all univariate analyses).
Conclusions
The GIDAC reviewed 34 proposals from 1998–2018. The majority were recommended for approval and later approved by the FDA, highlighting the GIDAC’s prominence in the regulatory process. COI are present among GIDAC panelists but decreasing over time and not associated with recommendations.

Abstract
Background Upper gastrointestinal (GI) endoscopic procedures are aerosol-generating, increasing the risk of healthcare workers (HCW) contracting Coronavirus disease 2019 (COVID-19). Aims To present a polycarbonate box (EndoBox) designed for use in upper GI endoscopy and evaluate its impact on the contamination of endoscopy staff during simulated procedures. Methods Simulated gastroscopies were performed using an upper body simulator placed in left lateral decubitus (LLD) and supine positions. The endoscopist and assistant wore personal protective equipment. Droplet exposure was measured using fluorescent abiotic surrogate particles. Two blinded observers independently viewed images from each scenario to qualitatively evaluate contamination levels. The primary outcome was the level of HCW contamination by droplets generated from a simulated cough with and without the EndoBox on the upper body simulator. The endoscopist’s ergonomic behaviour was also assessed using the Rapid Upper Limb Assessment (RULA) tool. Results Without the EndoBox, there was a higher level of contamination on the endoscopist when the upper body simulator is in the LLD position. A higher level of contamination was observed on the assistant when the simulator is in supine position. With the EndoBox, the contamination levels on the endoscopy staff were lower in both LLD and supine scenarios. The endoscopist’s ergonomics were rated 2 to 3 on the RULA tool when using the EndoBox. Conclusions The EndoBox reduces macroscopic droplet contamination during simulated gastroscopy. The endoscopist’s risk of musculoskeletal injury remained in the low risk categories as assessed by the RULA tool. Another advantage of the EndoBox design is the arch extending from the bottom that allows for removal of the box without withdrawing the endoscope. This enables rapid access to the patient’s airway if they experience respiratory distress. This study was limited by an inability to assess microscopic contamination and contamination at the level of the port or buttons when suction is applied. Within these limitations, the EndoBox may be a useful adjunct to traditional personal protective equipment. Funding Agencies SMHA AFP COVID-Related Innovation Funds

Abstract
Abstract
Background
Inflammatory Bowel Disease (IBD) studies have commonly relied on real-world evidence to evaluate different therapies. An emerging idea has been the use of propensity score matching as a statistical method to account for baseline characteristics in IBD patients. In retrospective studies, propensity score matching of patients helps reduce treatment assignment bias and mimic the effects of randomization. Recently, propensity-score matching has become an important tool in IBD studies comparing biologic therapeutics. Biologic medications are among the highest-grossing drugs worldwide, and their pharmaceutical producers make considerable payments to physicians to market them. In spite of this, there is a lack of evidence examining the role of undue industry influence among propensity-score matched comparative studies evaluating biologic therapeutics for IBD.
Aims
Given the documented association between IBD biologics and FCOI, we hypothesize a high burden of FCOI in propensity-score matched studies. The aim of this study was to evaluate the prevalence of disclosed & undisclosed financial conflicts of Interest (FCOI) in propensity-score matched comparison studies evaluating biologics for IBD.
Methods
We developed & ran a librarian-reviewed systematic search on EMBASE, MEDLINE, and Cochrane Library databases for all propensity-score matched retrospective studies comparing biologics for the treatment of IBD. Full-text retrieval & screening was performed on all studies in duplicate. 16 articles were identified. Industry payments to authors were only considered FCOI if they were made by a company producing a biologic that was included in the comparison study. Disclosed FCOI were identified by authors’ interests disclosures in full-texts. Any undisclosed FCOI among US authors were identified using the Centre for Medicare and Medicaid Services (CMS) Open Payments Database, which collects industry payments to physicians.
Results
Based on a preliminary analysis of 16 studies, there was at least one author with a relevant FCOI in 14 (88%) of the 16 studies. 14 studies (88%) had at least one disclosed FCOI, while 6 studies (37.5%) had at least one undisclosed FCOI. Among studies with disclosed FCOI, a mean of 40.2% (SD = 23.4%) of authors/study reported FCOI. Among studies with undisclosed FCOI, a mean of 18.8% (SD = 7.0%) of authors/study reported FCOI. The total dollar value of FCOIs was $1,974,328.3. The median conflict dollar value was $5,576.6 (IQR: $321.6 to $36,394.9).
Conclusions
We found a high burden of undisclosed FCOI (37.5%) among authors of propensity-score matched studies evaluating IBD biologics. Given the potential for undue industry influence stemming from such payments, authors should ensure better transparency with industry relationships.

Abstract
Abstract
Background
Clinical practice guidelines are evidence-based resources designed to inform clinical decision making. Often, superior evidence will support the inclusion of novel procedures and practices to replace older recommendations. Recommendation reversals occur when (a) superior quality evidence emerges to suggest the harm or non-beneficence of prior recommendations, and (b) that recommendation is not supplanted by a newer one.
Aims
The primary objective of this study was to describe the content, frequency and rationale for recommendation reversals in CPGs published by gastroenterological societies.
Methods
For this meta-epidemiologic study, we considered two criteria to define a recommendation reversal: (a) the more recent CPG makes a recommendation that contradicts a previously accepted practice; and (b) the prior recommendation is not replaced by any novel intervention. We searched CPGs published by 20 major GI societies from 1991- 2019. Guidelines were included if had at least two iterations with the same title and used a valid evidence rating system (such as GRADE). Explicit recommendations which reported definite levels of evidence and strength of recommendation were extracted.
Results
We identified 1022 clinical guidelines from GI societies over 28 years. 292 CPGs were included for data synthesis. 5985 explicit statements were extracted. 12 reversals were confirmed and are summarized in the Table. Six reversals (50.0%) occurred due to studies reporting non-beneficence and 3 (25.0%) occrred due to studies reporting harm. Three recommendations (25.0%) were reversed due to new clinical trials; 3 (25.0%) due to systematic reviews or meta-analyses; and 2 to conform with CPGs of other societies (16.7%).
Conclusions
We describe recommendation reversals made in gastroenterology CPGs, and the reasons thereof. Investigation of recommendation reversals allows for the identification of low-value medical practices. This reinforces the need for GI CPG committees to (1) iteratively review guidelines to re-evaluate recommendations made on low-quality evidence and; (2) refrain from making recommendations when evidence for the same is weak.

Background
The effect of right ventricular (RV) pacing on left ventricular (LV) function has been extensively evaluated, and so has the effect of the RV pacing lead on tricuspid valve function. However, the effects on RV function per se have not been evaluated systematically.
Purpose
We aimed to assess the RV dimensions and RV function six months after dual chamber pacemaker implantation
performed for atrioventricular (AV) block by detailed echocardiography, including three-dimensional (3D) echocardiography.
Method
All adult patients undergoing dual chamber pacemaker from January 2018 to March 2019 for symptomatic AV block with a structurally normal heart were included in the study. They underwent pre-procedure detailed echocardiography specifically directed at measuring RV dimensions and function [including 3D RV ejection fraction (EF)] and a repeat detailed echocardiogram at six-month follow-up, by the same echocardiographer. The echocardiographic parameters at baseline and after six-month follow-up were compared.
Results
All patients had more than 75% ventricular pacing in these six months. At six-month follow-up, there was no significant change in LVEF, while there was a mild decrease in RVEF as outlined in the Table 1. While there was some overlap between RVEF range of values at baseline and after six months, 23 (38.3%) patients showed a drop in RVEF by >5%.
Conclusion
Our study shows a change in several RV function parameters in a majority of patients six months after
pacemaker implantation for AV block.

Abstract
BACKGROUND The quality of case reports, which are often the first reported evidence for a disease, may be negatively affected by a rush to publication early in a pandemic. We aimed to determine the completeness of reporting (COR) for case reports published on coronavirus disease 2019 (COVID-19). METHODS We conducted a systematic search of the PubMed database for all single-patient case reports of confirmed COVID-19 published from Jan. 1 to Apr. 24, 2020. All included case reports were assessed for adherence to the CARE (Case Report) 31-item checklist, which was used to create a composite COR score. The primary outcome was the mean COR score assessed by 2 independent raters. Secondary outcomes included whether there was a change in overall COR score with certain publication factors (e.g., publication date) and whether there was a linear relation between COR and citation count and between COR scores and social media attention. RESULTS Our search identified 196 studies that were published in 114 unique journals. We found that the overall mean COR score was 54.4%. No one case report included all of the 31 CARE checklist items. There was no significant correlation between COR with either citation count or social media attention. INTERPRETATION We found that the overall COR for case reports on COVID-19 was poor. We suggest that journals adopt common case-reporting standards to improve reporting quality.

Abstract
Abstract
Background
Limited data exist on the optimal revascularization strategy for patients with left main coronary artery disease (LMCAD) and chronic kidney disease (CKD). We conducted a meta-analysis to compare the outcomes of coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) in this population.
Methods
Multiple electronic databases were queried for studies comparing CABG and PCI in CKD patients undergoing LMCAD (>50% diameter stenosis) revascularization. CKD was defined as estimated glomerular filtration rate of <60 ml/min/1.73 m2. The primary outcome was long-term major adverse cardiac and cerebrovascular events (MACCE), which was a composite of cardiovascular death, myocardial infarction (MI), stroke and repeat revascularization. Secondary outcomes included all-cause mortality, MI, stroke and repeat revascularization. Odds ratios (OR) and 95% confidence intervals (CI) were calculated. The analysis was performed using the DerSimonian and Laird random effect model.
Results
Six studies (4 observational, 2 randomized controlled trials) met inclusion criteria with a total of 2051 patients (CABG: 977, PCI: 1074). Patients undergoing CABG had a higher incidence of multi-vessel disease (74.7% vs 65.7%, p=0.01). At a mean follow-up of 3.4±1.1 years, MACCE was significantly lower in the CABG group (OR = 0.70, 95% CI 0.57–0.87; p=0.001) (Figure 1). The odds of MI or repeat revascularization were lower with CABG, whereas the odds of stroke were higher; no statistically-significant difference was seen in all-cause mortality.
Conclusion
This meta-analysis shows that CABG is associated with lower rates of MACCE and MI but with a higher rate of stroke compared to PCI in LMCAD patients with CKD.

Abstract
BACKGROUND AND AIMS Payments from pharmaceutical and medical device manufacturers to authors of clinical practice guidelines (CPGs) may influence practice recommendations. It is therefore important to evaluate the completeness of financial conflict of interest (FCOI) declarations among CPG authors. METHODS We performed a cross-sectional analysis of industry payments to authors of endoscopy guidelines published by 5 GI societies between 2014 and 2017. For each author we identified payments using the disclosure section of CPGs and the Centers for Medicare & Medicaid Services Open Payments (CMS-OP) database. We calculated the prevalence, monetary value, and type of declared and undeclared payments among authors. Payments were assessed for the calendar year of and before publication. RESULTS Thirty-seven CPGs were included in the analysis comprising 569 author entries (91 unique individuals; 66.43% men, 92.6% physicians, 66.4% academically affiliated). Four hundred fifty-one episodes (79%) involved FCOIs, 451 (79%) had undisclosed FCOIs in the CMS-OP, and 445 (77%) had FCOIs relevant to a CPG recommendation. The median undisclosed payment value was $4807.26 (interquartile range, $334.84-$20,579.75). Male authors (odds ratio, 2.23; 95% confidence interval, 1.47-3.39) and academically affiliated authors (odds ratio, 8.87; 95% confidence interval, 5.57-14.13) were significantly more likely to have undeclared payments (P < .001). No CPGs met all National Academy of Medicine criteria. CONCLUSIONS Recognizing concerns about the accuracy of the CMS-OP, there are substantial discrepancies between industry-reported payments and author self-disclosure. Additionally, there is a high prevalence of undisclosed payments by pharmaceutical and medical device manufacturers to these authors. Given the potential impact of these discrepancies and undisclosed payments on CPGs, more accurate reporting and alternative strategies for managing FCOI are needed.

Abstract
Background: Xanthogranulomatous pyelonephritis (XGP) is a rare chronic bacterial inflammation of the renal parenchyma and is often a diagnostic dilemma.Case Presentation: We present a challenging case of a patient with XGP. Initially thought to have had renal cell cancer she was treated accordingly with a partial nephrectomy. However, on the final pathology, she was found to have XGP and required further antibiotic therapy and referral to the infectious disease service.Discussion: Management of XGP and diagnostic pitfalls are discussed.Conclusion: XGP is a diagnostic and therapeutic dilemma. Partial Nephrectomy may be appropriate in management of XGP in select cases.

Abstract
Abstract
Background
Cardiovascular mortality is higher in developing countries. Part of that is suboptimal testing. Cardiac magnetic resonance (CMR) is the gold standard for measuring structure, function of the heart and adds incremental value by imaging scarring and to assess iron level. Despite the existence of MRI units, CMR is identified as a complex test, with poor training and availability in developing countries.
Purpose
To assess the potential impact of a faster CMR protocol at a multicentre level in developing countries; implementing it with an education program, for the assessment cardiomyopathies.
Methods
An international partnership. A rapid CMR protocol for the evaluation of cardiac volumes, function and tissue characterization (Cardiac Iron T2* and LGE for scar) Figure 1a. We deployed the protocol as a multicentre study: Argentina, Peru, India and South Africa accompanied by a program of education. Pre-scan clinical information, scanning data: complications, image quality and post-scan follow-up of participants for the assessment on impact, between 3 to 24 months.
Results
510 scans (4 countries, 6 cities, 12 centres) were performed with the rapid CMR protocol. Contrast studies in 378 (74%). There were no scan-related complications. Quality of the studies was maintained in a high level as an average of 89%. 97% of studies responded referral's question. All patients with contrast CMR scan have had at least one 2D echocardiogram before CMR. Average scan duration was 21±6 mins for contrast studies and 12±3 for non-contrast T2* protocol. The most common underlying diagnoses were non-ischaemic cardiomyopathy in 73% of participants (including cardiac iron level assessment in 26%, HCM in 17%, DCM in 15%), 27% for ischaemic cardiomyopathy and 15% for other pathologies. 4 of the 12 participant centres started to incorporate CMR for the first time. Findings impacted management in 60% of patients, including new diagnosis in 21% of participants. See table 1, figure 1b. For just cardiac iron assessment: 1/3 of participants had iron deposited in the heart with 14% of patients in severe levels.
Conclusions
CMR can be delivered faster and easier. When this abbreviated protocol is enabled with education, it can be implemented in developing countries with existing technology. This protocol shows high quality exam, with an important impact on patient's management.

Abstract
AIM To establish the correlation between clinical grading of papilloedema and diffusion abnormalities of optic nerve head (ONH) on diffusion-weighted imaging (DWI). MATERIALS AND METHODS Brain magnetic resonance imaging (MRI), including readout segmented echo planar imaging-based DWI, was performed in 32 patients with papilloedema and the same number of age- and sex-matched controls. Clinical grading of papilloedema was done according to the modified Frisén scale. Two neuroradiologists independently evaluated the MRI for ONH hyperintensity and apparent diffusion coefficient (ADC) value of ONH. The comparison between papilloedema clinical grade and qualitative grade of ONH hyperintensity and its presence between cases and control groups were done using the Chi-square test and Fisher's exact test, respectively. The comparison between mean ADC value of ONH among different grades and between cases and controls were done using analysis of variance (ANOVA)-F-test and Student's t-test, respectively. Receiver operating characteristic (ROC) analysis was done to calculate a cut-off ADC value between the case and control groups. RESULTS Significant correlation between ONH hyperintensity and mean ADC value of ONH with clinical grades of papilloedema and between cases and control groups were found. ONH hyperintensity was found to be a highly sensitive (87.5% for both) and specific (specificity 97.1% and 98.6% for two observers) sign of papilloedema. A mean cut-off ONH ADC value was found to have high sensitivity (96.83%) and specificity (95.31%) to distinguish between the cases and controls. CONCLUSIONS Diffusion parameters of ONH have significant correlation with clinical grading of papilloedema and can serve as a surrogate marker for intracranial pressure.

Abstract
AbstractEpilepsy is the commonest serious neurological problem faced by obstetricians and gynaecologists. Epidemiological studies estimate epilepsy to complicate 0.3–0.7% of all pregnancies.1 2 The importance of epilepsy in pregnancy lies in the fact that many women with epilepsy (WWE) have to go through their pregnancy while taking antiepileptic (AED) drugs. Both the seizures and AEDs can have harmful effects on the mother as well the foetus. Thus, during pregnancy, the clinician faces dual challenge of controlling seizures as well as preventing teratogenicity of AEDs.1 In this review we discuss the possible impact of seizures as well as AEDs on mother as well as the child. We try to answer some of the commonest questions which are relevant to successful management of pregnancy and ensuring birth of a healthy baby.
