We compared health services use, surgical rate, and specialist gastroenterologist care in rural and urban inflammatory bowel disease (IBD) patients in Canada.Methods: We used validated algorithms that were applied to population-based health administrative data to identify all people living with the following three Canadian provinces: Alberta, Manitoba, and Ontario (ON). We compared rural residents with urban residents for time to diagnosis, hospitalizations, outpatient visits, emergency department (ED) use, surgical rate, and gastroenterologist care. Multivariable regression compared the outcomes in rural/urban patients, controlling for confounders. Provincial results were meta-analyzed using random-effects models to produce overall estimates.Results: A total of 36,656 urban and 5,223 rural residents with incident IBD were included. Outpatient physician visit rate was similar in rural and urban patients. IBD-specific and IBD-related hospitalization rates were higher in rural patients (incidence rate ratio [IRR] 1.17, 95% CI 1.02–1.34, and IRR 1.27, 95% CI 1.04–1.56, respectively). The rate of ED visits in ON were similarly elevated for rural patients (IRR 1.53, 95% CI 1.42–1.65, and IRR 1.33, 95% CI 1.25–1.40). There were no differences in surgical rates or prediagnosis lag time between rural and urban patients. Rural patients had fewer IBD-specific gastroenterologist visits (IRR 0.79, 95% CI 0.73–0.84) and a smaller proportion of their IBD-specific care was provided by gastroenterologists (28.3% vs 55.2%, P65 years (33.0% vs 59.2%, P

Few studies have examined exercise placement within children-specific programming. This study aimed to investigate the frequency and type of exercise placement in children-specific television broadcasts and to compare placements on the UK and Irish television channels.Methods: Content analysis for five weekdays’ worth of children-specific television broadcasting totaling 82.5 hours on both the UK (British Broadcasting Corporation) and Irish (Radió Teilifís Éireann) television channels was performed. For the purposes of comparing the UK and Irish placements, analysis was restricted to programming broadcast between 6 am and 11.30 am. Exercise placements were coded based on type of activity, activity context, activity motivating factors and outcome, and characters involved.Results: A total of 780 cues were recorded during the total recording period. A wide variety of sports were depicted, but dancing-related cues were most commonly seen (n=163, 23.3%), with the majority of cues being of mild (n=365, 65.9%) or moderate (n=172, 31.0%) intensity. The majority of cues were associated with a positive outcome (n=404, 61.4%), and social motivations were most commonly seen (n=289, 30.3%). The Irish and the UK portrayals were broadly similar.Conclusion: This study highlights the wide variety of sports portrayed and the active effort undertaken by television stations to depict physical exercise and recreation in a positive light.

The recognition of the role of Helicobacter pylori in the pathogenesis of peptic ulcer disease has led to renewed interest in bismuth pharmacology since bismuth compounds have both anti-Helicobacter pylori and ulcer healing properties. The precise chemical structure of current bismuth compounds is not known. This has hindered the development of new and potentially more efficacious formulations. We have created two new compounds, 2-chloro-1,3-dithia-2-bismolane (CDTB) and 1,2-[bis(1,3-dithia-2-bismolane)thio]ethane (BTBT), with known structure. In a rat model of gastric ulceration, BTBT was comparable to, and CDTB was significantly less effective than colloidal bismuth subcitrate in healing cryoprobe-induced ulcers. However, both BTBT and CDTB inhibited H. pylori growth in vitro at concentrations <1/10 that of colloidal bismuth subcitrate. The effects on ulcer healing are not mediated by suppression of acid secretion, pepsin inhibition, or prostaglandin production. Since all treated animals received the same amount of elemental bismuth, it appears that the efficacy of bismuth compounds varies with compound structure and is not simply dependent on the delivery of bismuth ion. Because the structure of the novel compounds is known, our understanding of the relationship of bismuth compound structure and to biologic activity will increase. In the future it may be possible to design other novel bismuth compounds with more potent anti-H. pylori and ulcer healing effects. [ABSTRACT FROM AUTHOR]

Abstract Background Overweight and obesity is a growing problem in Ireland. Many parents are unaware when their child is overweight or obese. Our objectives were to examine parents’ perceptions of a healthy diet and their children’s BMI; and to evaluate the food offered to children in our paediatric in-patient unit. Findings A retrospective questionnaire was distributed to 95 patients and their families admitted over one month. Seventy-eight had BMI values calculated (42 males, 36 females). Twenty-one children (26.9%) were overweight/obese: 14/21 parents (66.7%) thought their child had a normal weight. Sixty percent of children served dinner in the hospital were given fried potatoes. Four had fruit/vegetables. Forty-six parents brought food into hospital, of these 14 brought purchased food. Conclusions This study highlights the problem of child obesity in Ireland and parental underestimation of this problem. The nutritional value of food served to children in hospital needs to be improved and hospital admissions used as opportunities to promote healthy eating habits.

Background and Aims: Since the onset of the Coronavirus disease 2019 (COVID-19) pandemic, there has been a significant opportunity to leverage virtual platforms for communication and dissemination of knowledge. An online survey was conducted to examine the viewpoints of World Gastroenterology Organization (WGO) leaders concerning the necessity, primary priority areas, and implementation strategies for a virtual global gastroenterology educational program., Methods: We conducted a survey of leaders of WGO member societies to assess their opinions on creating opportunities for global education using virtual platforms, identifying practical implementation steps and priority educational areas., Results: Responses were obtained from 57/117 (48.7%) contacted leaders with 56/57 (98.2%) identifying such a need. Five mutually exclusive priority educational topics were proposed in the survey: clinical gastroenterology, endoscopy, nutritional support, research methodology, and professional development. Overall, most participants prioritized clinical gastroenterology (45/57; 78.9%) and endoscopy/hand skills (27/57; 47.3%) as educational topics to be addressed by the virtual global gastroenterology educational program. A majority of WGO member society leaders surveyed favored monthly teaching activities (33/57; 57.8%), ideally carried out between 1500-2100 local time (31/57; 54.3%), ideally with no administrative fees (47/57; 82.4%)., Conclusions: This truly global survey of WGO member societies achieved a good response rate and provides important insights into the need for and scope of future virtual education programs under the aegis of the WGO.

The environment is changing rapidly under pressure from 3 related drivers: climate change, pollution, and biodiversity loss. These environmental changes are affecting digestive health and disease in multiple ways. Heat extremes can cause intestinal and hepatic dysfunction. Access to adequate amounts of food of high nutritional content and to clean water is under threat. Extreme weather is associated with flooding and enteric infections and affects the delivery of care through infrastructure loss. Air, water, and soil pollution from chemicals and plastics are emerging as risk factors for a variety of intestinal diseases including eosinophilic esophagitis, metabolic dysfunction associated fatty liver disease, digestive tract cancers, inflammatory bowel disease, and functional bowel disease. Migration of populations to cities and between countries poses a special challenge to the delivery of digestive care. The response to the threat of environmental change is well underway in the global digestive health community, especially with regard to understanding and reducing the environmental impact of endoscopy. Individuals, and peer societies, are becoming more engaged, and have an important role to play in meeting the challenge., (© 2024 The Authors.)

Background and study aims Adequacy of endoscope disinfection in resource-limited settings is unknown. Adenosine triphosphate (ATP) testing is useful for evaluation of endoscope reprocessing, and ATP <200 relative light units (RLUs) after manual endoscope cleaning has been associated with adequacy of endoscope disinfection. Methods Consecutive endoscopes undergoing reprocessing at five World Gastroenterology Organisation (WGO) training centers underwent ATP testing before and after an on-site educational intervention designed to optimize reprocessing practices. Results A total of 343 reprocessing cycles of 65 endoscopes were studied. Mean endoscope age was 5.3 years (range 1-13 years). Educational interventions, based on direct observation of endoscope reprocessing practices at each site, included refinements in pre-cleaning, manual cleaning, high-level disinfection, and endoscope drying and storage. The percentage of reprocessing cycles with post-manual cleaning ATP ≧200 decreased from 21.4% prior to educational intervention to 14.8% post-intervention ( P =0.11). In multivariable logistic modelling, gastroscopes were significantly less likely (odds ratio [OR] 0.04, 95% confidence interval [CI] 0.01-0.19; P <0.001) than colonoscopes to achieve post-manual cleaning ATP < 200. No other factor (educational intervention, study site, endoscope age) was significantly associated with improved outcomes. Endoscope ID was not significantly associated with ATP values, and sites that performed manual versus automated HLD did not have significantly different likelihood of post-manual cleaning ATP <200 (OR 1.18, 95% CI 0.56-2.50; P =0.67). Conclusions In resource-limited settings, approximately 20% of endoscope reprocessing cycles may result in inadequate disinfection. This was not significantly improved by a comprehensive educational intervention. Alternative approaches to endoscope reprocessing are needed., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest., (The Author(s).

Global warming and climate change are important worldwide issues which are a major human health threat. Climate change can affect the gastrointestinal (GI) system in many ways. Increased rainfall events and flooding may be associated with increased GI infections and hepatitis. Climate change could cause changes in gut microbiota, which may impact the pattern of GI diseases. The stress of access to essential needs such as clean water and food, the effects of forced migration, and natural disasters could increase brain-gut axis disorders. The association between air pollution and GI disorders is another challenging issue. There is a lot to do personally and professionally as gastroenterologists regarding climate change., Competing Interests: Competing Interests The authors declare no conflict of interest related to this work., (© 2023 Middle East Journal of Digestive Diseases.)

Background: The University of Limerick Cancer network (ULCaN) was established in 2019 with funding from the Health Research Institute at the University of Limerick in order to build a network between individuals in academia, primary and secondary care and the general public so that cancer services can be coordinated and more effective. The aim of this paper is to outline our experience of engaging with stakeholders to identify gaps in the cancer journey locally., Methods: Four focus group discussions were conducted with patients; their carers; members of the public; and healthcare providers with 2 main aims: 1) to investigate gaps in cancer services; 2) to identify knowledge, attitudes and opportunities available to promote cancer research. The focus groups were audio recorded, transcribed and thematically analysed., Results: 15 themes within the topics of cancer care, palliation, communication, clinical trials, diet and exercise and public and patient involvement in research and advocacy were identified. These include directing people to reliable information and navigating misinformation and stigma linked with cancer, promoting awareness of clinical trials and palliative care services and improving communication when multiple healthcare providers are involved., Conclusion: The need to make more coherent, efficient and integrated cancer research amongst local stakeholders was evident. Embedding patients and members of the public into ULCaN is an important deliverable for collaborative research., Competing Interests: Declaration of Competing Interest The authors are involved in cancer research., (Copyright © 2021.

Climate change has been described as the greatest public health threat of the 21st century. It has significant implications for digestive health. A multinational team with representation from all continents, excluding Antarctica and covering 18 countries, has formulated a commentary which outlines both the implications for digestive health and ways in which this challenge can be faced., (Copyright © 2021 by Wolters Kluwer, the American Gastroenterological Association, the British Society of Gastroenterology and BMJ Publishing Group, the World Gastroenterology Association.)

Objectives: We estimated and compared the travel related carbon emissions of the annual meeting of the Canadian Association of Gastroenterology between the two most common geographical locations of the meeting., Methods: We modelled the car, train and flight travel journey of each registrant to two annual meetings. One was held in Toronto, close to where the majority of Gastroenterogists live, the other in Banff in the west of the country. We used validated carbon emission outputs per kilometer of travel., Results: The average per capita distance travelled to the Toronto meeting was 2845 km, resulting in 0.540 tonnes (t) of CO 2 equivalent (CO 2 e) emitted per person. When the meeting was held in Banff emissions were 41% higher than those in Toronto with an average distance travelled of 3949 km and 0.760t of CO 2 e emitted per person. Almost all of the travel related carbon emissions for both meetings were generated by flying., Conclusions: Even when held close to the largest population centre, there is a large environmental impact from travel to annual meetings. Importantly, choice of meeting location has a very big impact on difference in carbon emissions. Societies need to consider the site of meetings and reduce the number of in-person attendees if they wish to reduce their carbon footprint. Hybrid models participants should be considered. Our analysis also suggests, other medical societies who wish to model their annual meetings can use a simplified model, using flying distance only, to estimate travel-related emissions., (© The Author(s) 2021.

Performance of endoscopic procedures is associated with a risk of infection from COVID-19. This risk can be reduced by the use of personal protective equipment (PPE). However, shortage of PPE has emerged as an important issue in managing the pandemic in both traditionally high and low-resource areas. A group of clinicians and researchers from thirteen countries representing low, middle, and high-income areas has developed recommendations for optimal utilization of PPE before, during, and after gastrointestinal endoscopy with particular reference to low-resource situations. We determined that there is limited flexibility with regard to the utilization of PPE between ideal and low-resource settings. Some compromises are possible, especially with regard to PPE use, during endoscopic procedures. We have, therefore, also stressed the need to prevent transmission of COVID-19 by measures other than PPE and to conserve PPE by reduction of patient volume, limiting procedures to urgent or emergent, and reducing the number of staff and trainees involved in procedures. This guidance aims to optimize utilization of PPE and protection of health care providers.

Background: It is necessary for health planners, educators and physician and patient organizations to be aware of trends in gastroenterologist (GI) numbers in order to ensure that patients have timely access to care., Methods: The number of GIs in practice and the number of trainees in the specialty was determined for 2018 using three national databases compared with previous years., Results: In 2018, there were 787 GIs in Canada, which equated to 2.1 GIs per 100,000 population. There are marked differences between provinces with numbers ranging from 1.1 to 2.9 per 100,000. There are 53 GIs specializing in pediatric GI care. Forty-six per cent of practitioners under the age of 35 years are female. Seventy-two residents are training in adult GI and six in pediatrics. Approximately 75% of fellows in adult and pediatric GI are training on temporary visas. The number of adult GIs is decreasing despite increasing national population growth and service demand. The numbers of trainees in both adult and pediatric GI are lower than in 2010. If these trends continue, wait times for GI care, which are already poor, will likely increase further., Conclusions: Continued monitoring of human resource numbers, patient access to care and validation of current data is required.The purpose of this report is to present the number of gastroenterologists (GIs), both in practice and in training, in Canada for 2018. We also wished to examine the 2018 numbers by province and gender, compare the 2018 numbers with those of previous years and describe the practice settings and organization., (© The Author(s) 2020.

The earth's atmosphere has warmed by about 1°C compared with preindustrial temperature. This is producing changes in the earth's climate and weather which have implications for gastrointestinal health and disease. Climate change will exacerbate current challenges with regard to provision of adequate nutrition and access to clean water. An increase in high rainfall events, flooding and droughts will be associated with an increase in enteric infections and hepatitis. Changes in habitat may result in altered distribution of gastrointestinal illness such as Vibrio cholera. Climate change will force migration between countries, and within countries, and will drive relocation from rural to urban areas, further straining sanitation and clean water provision. The infrastructure required to the delivery of gastrointestinal care is vulnerable to extreme weather events which will become more frequent. The Gastroenterology community needs to join the debate on climate change by organizing, educating, advocating, and supporting our political leaders as they face the enormous challenges posed by global warming.

Pathology is the study of disease and is an important component in medical education. However, with medical curriculum reform, its role and contribution to medical courses is under potential threat. We surveyed the status of pathology in all six Irish medical schools. Information was received from five direct undergraduate and four graduate entry programmes. Pathology was recognisable as a core subject in all but one of the medical schools, was generally taught in years two or three, and the greatest contact hours were for histopathology (44-102 hours). Lectures were the most common teaching modality, and all used single best or extended matching answer multiple-choice questions as part of assessments. Currently, pathology is very visible in Irish medical education but needs to remain relevant with the move to theme and case-based teaching. There is heavy reliance on lectures and on non-academic/full-time hospital staff to deliver teaching, which may not be sustainable., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Objective: To review and summarize the recently developed Canadian Association of Gastroenterology screening recommendations for patients with a family history of colorectal cancer (CRC) or adenoma from a family medicine perspective., Quality of Evidence: A systematic review and meta-analysis was performed to synthesize knowledge regarding family history and CRC. The Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE were searched with the following MeSH terms: colorectal cancers or neoplasms, screen or screening or surveillance, and family or family history. Known hereditary syndromes were excluded. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to establish certainty in reviewed evidence. Most recommendations are conditional recommendations with very low-quality evidence., Main Message: Individuals who have 1 first-degree relative (FDR) with CRC or an advanced adenoma diagnosed at any age are recommended to undergo colonoscopy every 5 to 10 years starting at age 40 to 50 years or 10 years younger than the age at diagnosis of the FDR, although fecal immunochemical testing at an interval of every 1 to 2 years can be used. Individuals with FDRs with non-advanced adenomas or a history of CRC in second-degree relatives should be screened according to average-risk guidelines. Lifestyle modification can statistically significantly decrease risk of CRC and should be considered in all patients., Conclusion: These guidelines acknowledge the many factors that can increase an individual's risk of developing CRC and allow for judgment to be employed depending on the clinical scenario. Lifestyle advice already given to patients for weight, blood pressure, and heart disease management will reduce the risk of CRC if implemented, and this combined with more targeted screening for higher-risk individuals will hopefully be successful in decreasing CRC mortality in Canada., (Copyright© the College of Family Physicians of Canada.)

Background & Aims: Inflammatory bowel diseases (IBDs) exist worldwide, with high prevalence in North America. IBD is complex and costly, and its increasing prevalence places a greater stress on health care systems. We aimed to determine the past current, and future prevalences of IBD in Canada., Methods: We performed a retrospective cohort study using population-based health administrative data from Alberta (2002-2015), British Columbia (1997-2014), Manitoba (1990-2013), Nova Scotia (1996-2009), Ontario (1999-2014), Quebec (2001-2008), and Saskatchewan (1998-2016). Autoregressive integrated moving average regression was applied, and prevalence, with 95% prediction intervals (PIs), was forecasted to 2030. Average annual percentage change, with 95% confidence intervals, was assessed with log binomial regression., Results: In 2018, the prevalence of IBD in Canada was estimated at 725 per 100,000 (95% PI 716-735) and annual average percent change was estimated at 2.86% (95% confidence interval 2.80%-2.92%). The prevalence in 2030 was forecasted to be 981 per 100,000 (95% PI 963-999): 159 per 100,000 (95% PI 133-185) in children, 1118 per 100,000 (95% PI 1069-1168) in adults, and 1370 per 100,000 (95% PI 1312-1429) in the elderly. In 2018, 267,983 Canadians (95% PI 264,579-271,387) were estimated to be living with IBD, which was forecasted to increase to 402,853 (95% PI 395,466-410,240) by 2030., Conclusion: Forecasting prevalence will allow health policy makers to develop policy that is necessary to address the challenges faced by health systems in providing high-quality and cost-effective care., (Copyright © 2019 AGA Institute.
