Patient and Public Involvement in Inflammatory Bowel Disease Research-A Scoping Review.

Background: Interest in patient and public involvement in research has grown. Medical, health, and social care research has demonstrated several benefits of patient and public engagement, such as empowering user input and reducing attrition rates in clinical trials. To date, no study has reviewed patient engagement in inflammatory bowel disease (IBD).

Interobserver Reliability of the Paris Classification for Superficial Gastrointestinal Tract Neoplasms: A Systematic Review.

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.

Video-based interventions to improve self-assessment accuracy among physicians: A systematic review.

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.

Global trends in training and credentialing guidelines for gastrointestinal endoscopy: a systematic review.

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.

Validity evidence for observational ERCP competency assessment tools: a systematic review.

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.

Preventing Surgery-Induced NK Cell Dysfunction Using Anti-TGF-β Immunotherapeutics.

Natural Killer (NK) cell cytotoxicity and interferon-gamma (IFNγ) production are profoundly suppressed postoperatively. This dysfunction is associated with increased morbidity and cancer recurrence. NK activity depends on the integration of activating and inhibitory signals, which may be modulated by transforming growth factor-beta (TGF-β).

Interventions to improve the quality of screening-related colonoscopy: protocol for a systematic review and network meta-analysis of randomised controlled trials.

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.

Financial Conflicts of Interest in Propensity Score-Matched Studies Evaluating Biologics and Biosimilars for Inflammatory Bowel Disease.

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.

Accuracy of self-assessment in gastrointestinal endoscopy: a systematic review and meta-analysis.

Background: Assessment is necessary to ensure both attainment and maintenance of competency in gastrointestinal (GI) endoscopy, and this can be accomplished through self-assessment. We conducted a systematic review with meta-analysis to evaluate the accuracy of self-assessment among GI endoscopists.

Methods: This was an individual participant data meta-analysis of studies that investigated self-assessment of endoscopic competency.

Educational interventions to improve ergonomics in gastrointestinal endoscopy: a systematic review.

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.

A Translational Randomized Trial of Perioperative Arginine Immunonutrition on Natural Killer Cell Function in Colorectal Cancer Surgery Patients.

Background: Surgery results in severe impairment of natural killer (NK) cell cytotoxicity (NKC) and activity (NKA, cytokine secretion), and a dramatic drop in arginine levels. Postoperative immunosuppression is associated with increased complications and recurrence. Perioperative arginine is reported to reduce postoperative complications.

Recommendation Reversals in Gastroenterology Clinical Practice Guidelines.

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.

Primary biliary cholangitis: perception and expectation of illness.

Unlabelled: An important tool to explore personal experience of symptoms, treatment and clinical outcome is stratification of illness perception in patients affected by PBC.

Aim: To assess the perception of illness in a cohort of Italian patients with PBC.

Methods: Between June and December 2019, a specific questionnaire was administered to a pool of 210 patients from 7 tertiary Italian centers, in order to identify and assess the patient's past history, symptoms and their impact on the quality of life, follow-up, treatment and perceived satisfaction of patients toward the provided care.

Outcomes for upper gastrointestinal bleeding during the first wave of the COVID-19 pandemic in the Toronto area.

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).

The Extra Virgin Olive Oil Polyphenol Oleocanthal Exerts Antifibrotic Effects in the Liver.

Liver fibrosis, which is the outcome of wound-healing response to chronic liver damage, represents an unmet clinical need. This study evaluated the anti-fibrotic and anti-inflammatory effects of the polyphenol oleocanthal (OC) extracted from extra virgin olive oil (EVOO) by an approach. The hepatic cell lines LX2 and HepG2 were used as models.

Do authors of research funded by the Canadian Institutes of Health Research comply with its open access mandate?: A meta-epidemiologic study.

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.

Folic Acid-Targeted Paclitaxel-Polymer Conjugates Exert Selective Cytotoxicity and Modulate Invasiveness of Colon Cancer Cells.

Although selective tumor delivery of anticancer drugs has been sought by exploiting either passive targeting or by ligand-mediated targeting, a selective anticancer therapy remains an unmet medical need. Despite the advances which have been achieved by nanomedicines, nanosystems such as polymer-drug conjugates still miss the goal of clinical efficacy. In this study, we demonstrated that polymer-drug conjugates require a thoroughly chemical design and the right targeting agent/polymer ratio to be selective and effective towards cancer cells.
