- INTRODUCTION:Gastrointestinal symptoms in irritable bowel syndrome (IBS) have been correlated with psychological factors using retrospective symptom assessment. However, real-time symptom assessment might reveal the interplay between abdominal and affective symptoms more reliably in a longitudinal perspective. The aim was to evaluate the association between stress and abdominal pain, using the Experience Sampling Method (ESM) as a real-time, repeated measurement method.METHODS:Thirty-seven patients with IBS (26 women; mean age 36.7 years) and 36 healthy controls (HC; 24 women; mean age 31.1 years) completed an electronic ESM during 7 consecutive days. Abdominal pain and stress were scored on an 11-point Numeric Rating Scale at a maximum of 10 random moments each day.RESULTS:Abdominal pain scores were 2.21 points higher in patients with IBS compared with those in HC (P < 0.001), whereas stress levels did not differ significantly (B: 0.250, P = 0.406). In IBS, a 1-point increase in stress was associated with, on average, 0.10 points increase in abdominal pain (P = 0.017). In HC, this was only 0.02 (P = 0.002). Stress levels at t = -1 were not a significant predictor for abdominal pain at t = 0 in both groups, and vice versa.DISCUSSION:Our results demonstrate a positive association between real-time stress and abdominal pain scores and indicate a difference in response to stress and not a difference in experienced stress per se. Furthermore, an in-the-moment rather than a longitudinal association is suggested. This study underlines the importance of considering the individual flow of daily life and supports the use of real-time measurement when interpreting potential influencers of abdominal symptoms in IBS.

- Background and objectiveNational patient registers are valuable in epidemiological studies. To ensure high-quality data for studies of irritable bowel syndrome (IBS), this study aimed to validate the ICD-10 code for IBS in the Swedish National Patient Register.MethodsThe positive predictive values (PPV) for IBS defined by the Rome criteria were calculated based on a review of medical records of randomly selected individuals with a first-ever diagnostic listing of IBS in the Swedish National Patient register in the year 2005 (Rome II criteria) or 2010 (Rome III criteria).Key results340 medical records were reviewed (172 from 2005 and 168 from 2010). The majority of patients were females (74%), and the mean age was 42 years. IBS used in any type of department had a PPV of 76% (95% confidence interval 71-80%), which increased to 80% (76-84%) when we included individuals likely to have IBS but where information about some aspects of the Rome criteria was lacking in the medical record. Two highly specialized gastroenterological departments had the best PPV, 96%, while departments of internal medicine in general had a PPV of 82% (80-95%). The PPV for the IBS subtype was 62% (55-67%). The PPVs were not significantly different comparing the two time periods investigated.Conclusion and inferencesThe validity of a register-based definition of IBS in the Swedish National Patient register is high and can be used to identify patients with IBS in observational research. The data source, i.e., type of hospital and department, influences reliability.

- BackgroundDisorders of Gut-Brain Interaction (DGBI) are highly prevalent worldwide, but their effect on work productivity has not gained much attention. Aims and MethodsWe aimed to compare work productivity and activity impairment (WPAI) in persons with and without DGBI in a large population-based cohort and identify factors independently associated with WPAI in subjects with DGBI. Data were collected from Germany, Israel, Italy, Japan, the Netherlands, Poland, Spain and Sweden via Internet surveys as part of the Rome Foundation Global Epidemiology Study. Apart from the Rome IV diagnostic questionnaire, questionnaires evaluating WPAI related to general health (WPAI:GH), psychological distress (PHQ-4), somatic symptom severity (PHQ-15) and other factors were assessed. ResultsOf the 16,820 subjects, 7111 met the criteria for DGBI according to the Rome IV diagnostic questionnaire. Subjects with DGBI were younger (median (interquartile range) age 43 (31-58) vs. 47 (33-62)) and more often female (59.0% vs. 43.7%) compared to subjects without DGBI. Subjects with DGBI had higher absenteeism, presenteeism (poor work productivity due to illness), overall work impairment and activity impairment (p < 0.001) compared with subjects without. For subjects with DGBI affecting more than one anatomical region, WPAI was incrementally higher for each additional region. There were significant differences in WPAI for subjects with DGBI in different countries. Subjects from Sweden had the highest overall work impairment and from Poland the lowest. Using multiple linear regression, male sex, fatigue, psychological distress, somatic symptom severity and number of anatomical regions were independently associated with overall work impairment (p < 0.05 for all). ConclusionIn the general population, people with DGBI have substantial WPAI compared with those without DGBI. The reasons for these findings should be explored further, but having multiple DGBI, psychological distress, fatigue and somatic symptom severity seem to contribute to this impairment associated with DGBI.

- Background/Objectives The global epidemiology of gastroparesis is unknown. The European UEG and European Society for Neurogastroenterology and motility consensus defines Gastroparesis as a condition characterized by delayed gastric emptying in the absence of mechanical obstruction, with a symptom pattern of nausea and/or vomiting and overlapping postprandial distress syndrome (PDS). Real-world evidence of this gastroparesis-like symptom pattern is a crucial step in understanding the epidemiology of gastroparesis. Methods In the Rome Foundation Global Epidemiology Study, 54,127 respondents from 26 countries completed the Rome IV Diagnostic Questionnaire and variables associated with disorders of gut-brain interaction via Internet. We selected subjects with gastroparesis-like symptoms (GPLS) (nausea and/or vomiting >= 1 day/week and simultaneous PDS). Patients reporting organic gastrointestinal disease, or fulfilling criteria for self-induced vomiting, cyclic vomiting or cannabinoid hyperemesis syndrome were excluded. We determined prevalence, associated comorbidities, quality of life (QoL) (PROMIS Global-10), symptoms of anxiety and depression (PHQ-4), somatic symptoms (PHQ-12), and healthcare utilization. Results The global prevalence of GPLS was 0.9% overall and 1.3% among diabetic individuals. Subjects with GPLS showed frequent overlapping of epigastric pain syndrome and irritable bowel syndrome. Subjects with GPLS had significantly lower body mass index, QoL, more non-gastrointestinal somatic complaints, symptoms of anxiety and depression, higher medication usage and doctor visits in the overall and diabetic population, compared to subjects without these symptoms. Conclusions GPLS are common worldwide and more common in diabetic patients. The symptom complex is associated with multiple aspects of illness and an increased healthcare consumption.

- Irritable bowel syndrome (IBS) is a functional disorder of brain-gut interactions. Differential brain responses to rectal distention between IBS and healthy controls (HCs) have been demonstrated, particularly in the pain matrix and the default mode network. This study aims to compare resting-state functional properties of these networks between IBS patients and HCs using graph analysis in two independent cohorts. We used a weighted graph analysis of the adjacency matrix based on partial correlations between time series in the different regions in each subject to determine subject specific graph measures. These graph measures were normalized by values obtained in equivalent random networks. We did not find any significant differences between IBS patients and controls in global normalized graph measures, hubs, or modularity structure of the pain matrix and the DMN in any of our two independent cohorts. Furthermore, we did not find consistent associations between these global network measures and IBS symptom severity or GI-specific anxiety but we found a significant difference in the relationship between measures of psychological distress (anxiety and/or depressive symptoms) and normalized characteristic path length. The responses of these networks to visceral stimulation rather than their organisation at rest may be primarily disturbed in IBS.

- Background Change in bowel habit as a sole alarm symptom for colorectal cancer is disputed. Objective We investigated the diagnostic value of change in bowel habit for colorectal cancer, particularly as a single symptom and within different age groups. Methods This retrospective cohort study examined colorectal cancer fast track referrals and outcomes across four Swedish hospitals (April 2016-May 2017). Entry criteria constituted one or more of three alarm features: anaemia, visible rectal bleeding, or change in bowel habit for more than 4 weeks in patients over 40 years of age. Patients were grouped as having only change in bowel habit, change in bowel habit plus anaemia/bleeding or anaemia/bleeding only. Results Of 628 patients, 22% were diagnosed with colorectal cancer. There were no cases of colorectal cancer in the only change in bowel habit group under 55 years, while this was 6% for 55-64 years, 8% for 65-74 years and 14% for 75 years and older. Among subjects under 55 years, 2% with anaemia/bleeding had colorectal cancer, this increased to 34% for 55 years and older (P < 0.0001). Change in bowel habit plus anaemia/bleeding gave a colorectal cancer prevalence of 16% in under 55 years and increased to 30% for 55 years and older (P = 0.07). Conclusion Change in bowel habit as the only alarm feature has a low diagnostic yield for colorectal cancer in patients under 55 years.

- Background & Aims: Prolonged colon transit times may increase the contact time between potential carcinogens in the stool and the colonic mucosa. Nonetheless, previous studies have yielded conflicting results connecting chronic constipation with the risk of colorectal cancer (CRC). We examined the association between chronic constipation and later CRC. Methods: In this nationwide case-control study, we identified 41,299 CRC cases by colorectal biopsy in Sweden between July 2007 and December 2016 and matched them to 203,181 age- and sex-matched controls from the general population. We compared odds of earlier chronic constipation (defined as ≥2 laxative prescriptions in the Prescribed Drug Register with ≥6 months between the first and last prescription) between CRC cases and controls using logistic regression. In separate analyses, we compared odds of earlier constipation between CRC cases and sibling comparators, but also examined earlier risk of having an inpatient/outpatient specialty diagnosis of chronic constipation before CRC. Results: Overall, 3943 patients with CRC met our criteria for chronic constipation before CRC. The crude proportion of chronic constipation in CRC patients was 9.5% compared with 8.8% in controls. After multivariable adjustment, there was a modest association between chronic constipation and later CRC (odds ratio [OR], 1.10; 95% CI, 1.06–1.14) that vanished using sibling comparators to control for residual confounding (OR, 1.04; 95% CI, 0.97–1.13). In a sensitivity analysis of 126,650 CRC patients diagnosed from 1989 to 2016, we found no association with earlier chronic constipation diagnosed in inpatient/outpatient specialty clinics (OR, 0.88; 95% CI, 0.75–1.04). Conclusions: In a nationwide case-control study, chronic constipation was not associated with later CRC. © 2021 AGA Institute

- INTRODUCTION: Mortality concern is a frequent driver of care seeking in patients with irritable bowel syndrome (IBS). Data on mortality in IBS are scarce, and population-based studies have been limited in size. We examined mortality in IBS. METHODS: A nationwide, matched, population-based cohort study was conducted in Sweden. We identified 45,524 patients undergoing a colorectal biopsy at any of Sweden’s 28 pathology departments and with a diagnosis of IBS from 2002 to 2016 according to the National Patient Register, a nationwide registry of inpatient and outpatient specialty care. We compared the mortality risk between these individuals with IBS and age- and sex-matched reference individuals (n 5 217,316) from the general population and siblings (n 5 53,228). In separate analyses, we examined the role of mucosal appearance for mortality in IBS. Finally, we examined mortality in 41,427 patients with IBS not undergoing a colorectal biopsy. Cox regression estimated hazard ratios (HRs) for death. RESULTS: During follow-up, there were 3,290 deaths in individuals with IBS (9.4/1,000 person-years) compared with 13,255 deaths in reference individuals (7.9/1,000 person-years), resulting in an HR of 1.10 (95% confidence interval [CI] 5 1.05–1.14). After adjustment for confounders, IBS was not linked to mortality (HR 5 0.96; 95% CI 5 0.92–1.00). The risk estimates were neutral when patients with IBS were compared with their siblings. The underlying mucosal appearance on biopsy had only a marginal impact on mortality, and patients with IBS not undergoing a colorectal biopsy were at no increased risk of death (HR 5 1.02; 95% CI 5 0.99–1.06). DISCUSSION: IBS does not seem to confer an increased risk of death. Copyright © 2020 by The American College of Gastroenterology.
