Abstract
Background and Aim Functional bowel disorders (FBDs), including irritable bowel syndrome (IBS) and others, are conditions without a physically identifiable etiology that, as a result, are difficult to treat. Alternatives to traditional medical interventions are needed because IBS patients require more of physician time and higher healthcare spending. The goal of this study was to determine the efficacy of alternative lifestyle interventions for patients with FBDs seen in an integrative medicine (IM) clinic at an academic medical center. Methods We performed a retrospective chart review to determine whether patients with FBDs had improvement in symptoms following predominantly nutrition-based IM interventions that included recommendations for dietary supplements and elimination diets. We measured symptoms before and after intervention (average time between measurements 8.75 months) using a medical symptoms questionnaire (MSQ) commonly used to quantify symptom change in IM clinics. Results Digestive tract symptoms, as measured by the MSQ, improved significantly in patients (n = 57) with FBDs following IM intervention. The MSQ Digestive Tract subtotal for FBD patients decreased from 10.2 (SD, 5.4) to 7.2 (SD, 5.2) (P < 0.001) after IM intervention. Conclusions Patients in an IM clinic had improved digestive tract symptoms scores following IM intervention. Because nutrition-based interventions were the primary intervention recommended by IM providers, primary care physicians and gastroenterologists may wish to consider referring FBD patients to registered dietitian-nutritionists (RDNs) skilled in implementing elimination diets.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder associated with a wide range of clinical symptoms. Some researchers have used cluster analysis (CA), a group of non-supervised learning methods that identifies homogenous clusters within different entities based on their similarity. OBJECTIVE AND METHODS This literature review aims to identify published articles that apply CA to IBS patients. We searched relevant keywords in PubMed, Embase, Web of Science, and Scopus. We reviewed studies in terms of the selected variables, participants' characteristics, data collection, methodology, number of clusters, clusters' profiles, and results. RESULTS Among the 14 articles focused on the heterogeneity of IBS, eight of them utilized K-means Cluster Analysis (K-means CA), four employed Hierarchical Cluster Analysis, and only two studies utilized Latent Class Analysis. Seven studies focused on clinical symptoms, while four articles examined anocolorectal functions. Two studies were centered around immunological findings, and only one study explored microbial composition. The number of clusters obtained ranged from two to seven, showing variation across the studies. Males exhibited lower symptom severity and fewer psychological findings. The association between symptom severity and rectal perception suggests that altered rectal perception serves as a biological indicator of IBS. Ultra-slow waves observed in IBS patients are linked to increased activity of the anal sphincter, higher anal pressure, dystonia, and dyschezia. CONCLUSION IBS has different subgroups based on different factors. Most IBS patients have low clinical severity, good QoL, high rectal sensitivity, delayed left colon transit time, increased systemic cytokines, and changes in microbial composition, including increased Firmicutes-associated taxa and depleted Bacteroidetes-related taxa. However, the number of clusters is inconsistent across studies due to the methodological heterogeneity. CA, a valuable non-supervised learning method, is sensitive to hyperparameters like the number of clusters and random initialization of cluster centers. The random nature of these parameters leads to diverse outcomes even with the same algorithm. This has implications for future research and practical applications, necessitating further studies to improve our understanding of IBS and develop personalized treatments.

Abstract
Irritable bowel syndrome (IBS) is a complicated gut-brain axis disorder that has typically been classified into subgroups based on the major abnormal stool consistency and frequency. The presence of components other than lower gastrointestinal (GI) symptoms, such as psychological burden, has also been observed in IBS manifestations. The purpose of this research is to redefine IBS subgroups based on upper GI symptoms and psychological factors in addition to lower GI symptoms using an unsupervised machine learning algorithm. The clustering of 988 individuals who met the Rome III criteria for diagnosis of IBS was performed using a mixed-type data clustering algorithm. Nine sub-groups emerged from the proposed clustering: (I) High diarrhea, pain, and psychological burden, (II) High upper GI, moderate lower GI, and psychological burden, (III) High psychological burden and moderate overall GI, (IV) High constipation, moderate upper GI, and high psychological burden, (V) moderate constipation and low psychological burden, (VI) High diarrhea and moderate psychological burden, (VII) moderate diarrhea and low psychological burden, (VIII) Low overall GI, and psychological burden, (IX) Moderate lower GI, and low psychological burden. The proposed procedure led to the discovery of new homogeneous clusters in addition to certain well-known Rome sub-types for IBS.

Abstract
Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder characterized by chronic abdominal pain and altered bowel habits. It can be subclassified in different subtypes according to the main clinical manifestation: constipation, diarrhea, mixed, and unclassified. Over the past decade, the role of gut microbiota in IBS has garnered significant attention in the scientific community. Emerging research spotlights the intricate involvement of microbiota dysbiosis in IBS pathogenesis. Studies have demonstrated reduced microbial diversity and stability and specific microbial alterations for each disease subgroup. Microbiota-targeted treatments, such as antibiotics, probiotics, prebiotics, synbiotics, fecal microbiota transplantation, and even diet, offer exciting prospects for managing IBS. However, definitive conclusions are hindered by the heterogeneity of these studies. Further research should focus on elucidating the mechanisms, developing microbiome-based diagnostics, and enabling personalized therapies tailored to an individual's microbiome profile. This review takes a deep dive into the microscopic world inhabiting our guts, and its implications for IBS. Our aim is to elucidate the complex interplay between gut microbiota and each IBS subtype, exploring novel microbiota-targeted treatments and providing a comprehensive overview of the current state of knowledge.

Abstract
Irritable Bowel Syndrome (IBS) is a functional disorder of the gastrointestinal tract characterized by abdominal pain and altered bowel habits. It has a prevalence of 10 to 25% in the United States and has a high disease burden, as evidenced by reduced quality of life, decreased work productivity and increased healthcare utilization and costs. IBS has been associated with several intra-intestinal and extra-intestinal conditions, including psychiatric comorbidities. Although the pathophysiology of IBS has not been fully elucidated, it involves dysregulation of communication between the brain and gut (brain–gut axis) which is associated with alterations in intestinal motility, gut permeability, visceral hypersensitivity and gut microbiota composition. The purpose of this article is to review the role the gut microbiota plays in the pathophysiology of IBS, understand factors that affect the gut microbiome and explore the microbiome as a target of treatment.

Abstract
Background: Irritable bowel syndrome (IBS) reduces patients' quality of life and causes great burdens due to its unclear pathogenesis and criteria for diagnosis. This study aimed to explore the differences in prevalence and the influencing factors for IBS and its subtypes. Methods: The UK Biobank surveyed 174,771 adult participants who completed the Digestive Health Questionnaire (DHQ) through emails and websites. DHQ included the Rome III criteria, IBS symptom severity score, and Patient Health Questionnaire 12 Somatic Symptom score. The UK Biobank also asked regarding previous IBS diagnosis, diagnosis for post-infectious IBS (PI-IBS), and environmental exposures and associated conditions (including anxiety or depression, based on treatment sought or offered). Pearson's Chi-squared test or Wilcoxon's rank-sum test was used for potential associations. Binary logic regression based on sex stratification was used to examine associations between selected factors and IBS and its subtypes. Results: This study included 31,918 participants who met the Rome III criteria for IBS. The pooled prevalence of IBS in the UK Biobank was 18.3%, with mixed IBS as the predominant subtype (59.0%), followed by diarrhea-predominant IBS (25.1%), constipation-predominant IBS (14.7%), and untyped IBS (1.1%). IBS was significantly associated with somatization (male: OR = 5.326, 95% CI = 4.863-5.832; female: OR = 4.738, 95% CI = 4.498-4.992) and coeliac disease (male: OR = 4.107, 95% CI = 3.132-5.385; female: OR = 3.783, 95% CI = 3.310-4.323). Differences in antibiotics and mental status were presented among subtypes and sex. Furthermore, 1,787 individuals were diagnosed with PI-IBS in the group of patients with IBS. The prevalence of PI-IBS in IBS was 16.6% in the UK Biobank, and it was characterized by diarrhea, fever, bloody diarrhea, and vomiting. Conclusion: Somatization and coeliac disease are primary risk factors for IBS. Distinguishing differential risk factors is critical for the precise diagnosis and treatment of IBS subtypes, particularly sex-specific differences in mental health status. General practitioners should focus on the treatment according to IBS subtypes.

Abstract
Introduction A diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) is an effective way to reduce gut symptoms in people with irritable bowel syndrome (IBS). This diet reduces the intake of fermentable fibres, leading to changes of the gut microbiota and insufficient fermentation in the large bowel, resulting in reduced production of short-chain fatty acids (SCFAs), such as butyrate, which has unfavourable implications for gut health, sleep and mental health. This study will examine the effect of Fibre-fix, a supplement containing a mix of dietary fibres, on the human gut microbiome composition, fermentative capacity, sleep, quality of life (QOL) and mental health of people with IBS who consume a low FODMAP diet (LFD). Methods and analysis A randomised, double-blind, placebo-controlled, study design is proposed to examine whether Fibre-fix added to an existing LFD may help modulate gastrointestinal function, improve markers of sleep, mental health and promote QOL in patients with IBS. Participants will provide stool and blood samples, daily bowel symptoms diaries and 3-day diet records. Additionally, they will complete validated questionnaires relating to FODMAP intake, sleep, mental health and QOL before and after a 3-week intervention. Gut health will be assessed via faecal microbiome composition, faecal pH and SCFA levels. Alteration of sleep will be recorded using an actigraphy device worn by all participants over the whole study. Multivariate analysis will be used to examine the gut microbiome and repeated measures Analysis of variance (ANOVA) will be used for dependent variables from questionnaires related to bowel symptoms, stool type, sleep, mental health and QOL to assess the differences between intervention and control groups after adjustment for confounding variables. Ethics and dissemination Ethics approval was obtained from the Human Research Ethics Committee of Edith Cowan University (2019-00619-YAN). Results will be disseminated in peer-review journal publications, and conference presentations. Participants will be provided with a summary of findings once the study is completed. If Fibre-fix is shown to result in favourable changes in gut microbial composition, SCFA production, sleep and mental well-being without exacerbating symptoms, this will provide additional dietary management options for those with IBS following an LFD. Trial registration number ACTRN12620000032954.

Abstract
Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder affecting 4-5% of the global population. This disorder is associated with gut microbiota, diet, sleep, and mental health. This scoping review therefore aims to map existing research that has administrated fibre-related dietary intervention to IBS individuals and reported outcomes on at least two of the three following themes: gut microbiota, sleep, and mental health. Five digital databases were searched to identify and select papers as per the inclusion and exclusion criteria. Five articles were included in the assessment, where none reported on all three themes or the combination of gut microbiota and sleep. Two studies identified alterations in gut microbiota and mental health with fibre supplementation. The other three studies reported on mental health and sleep outcomes using subjective questionnaires. IBS-related research lacks system biology-type studies targeting gut microbiota, sleep, and mental health in patients undergoing diet intervention. Further IBS research is required to explore how human gut microbiota functions (such as short-chain fatty acids) in sleep and mental health, following the implementation of dietary pattern alteration or component supplementation. Additionally, the application of objective sleep assessments is required in order to detect sleep change with more accuracy and less bias.

Relationships Between Abdominal Pain and Fatigue With Psychological Distress as a Mediator in Women With Irritable Bowel Syndrome. Gastroenterol Nurs 2020; 43:28-39.

Abstract
Women with irritable bowel syndrome often report fatigue, along with abdominal pain and psychological distress (i.e., depression and anxiety). There is little information about the relationships among these symptoms. Using a secondary data analysis (N = 356), we examined the relationship between abdominal pain and fatigue and whether psychological distress mediates the effect of abdominal pain on fatigue in both across women and within woman with irritable bowel syndrome. Data gathered through a 28-day diary were analyzed with linear regressions. The across-women and within-woman relationships among same-day abdominal pain, fatigue, and psychological distress were examined. Within-woman relationships were also examined for directionality among symptoms (i.e., prior-day abdominal pain predicts next-day fatigue and prior-day fatigue predicts next-day abdominal pain). In across-women and within-woman analyses on the same day, abdominal pain and fatigue were positively correlated. In within-woman analyses, abdominal pain predicted next-day fatigue, but fatigue did not predict next-day pain. In across-women and within-woman analyses, psychological distress partially mediated the effects of abdominal pain on fatigue. Symptom management incorporating strategies to decrease both abdominal pain and psychological distress are likely to reduce fatigue. Nursing interventions, such as self-management skills to reduce abdominal pain and psychological distress, may have the added benefit of reducing fatigue in irritable bowel syndrome.

Abstract
In order to foster animal welfare as well as high quality of research, many countries regulate by law that the severity of animal experiments must be evaluated and considered when performing biomedical research. It is well accepted that multiple parameters rather than a single readout parameter should be applied to describe animal distress or suffering. However, since the performance of readout parameters for animal distress is rarely defined and methods for multivariate analysis have only in rare cases been used, it is not known which methodology is most appropriate to define animal distress. This study used receiver operating characteristic curve analysis to quantify the performance of burrowing activity, body weight change and a distress score of mice after induction of liver damage by bile duct ligation or carbon tetrachloride. In addition, Support Vector Machine classification was used to compare the distress of these mouse models. This approach demonstrated that bile duct ligation causes much more distress than carbon tetrachloride-induced liver damage. This study, therefore, provides a prototype how to compare two animal models by considering several readout parameters. In the future these or similar methods for multivariate analysis will be necessary, when assessing and comparing the severity of animal models.

Abstract
Functional gastrointestinal disease is one in which gastrointestinal symptoms persist chronically or recurrently. This disease is challenging because it does not have an organic cause that can be detected in routine laboratory tests. Among them, the symptoms of irritable bowel syndrome (IBS), which is a type of functional gastrointestinal tract disease, include abnormal bowel movements associated with abdominal pain. However, no specific test has been established to definitively diagnose these diseases, including IBS. The traditional Rome IV diagnostic criteria are used to diagnose IBS by assessing subjective symptoms. However, it has been suggested that IBS is difficult to diagnose using the Rome IV criteria among unconscious or cognitively impaired patients. It is recommended that abdominal ultrasonography be used to assess IBS with diarrhea and constipation. Previously, constipation among elderly people who ingested food orally was objectively assessed by ultrasound, and colonic fecal distribution patterns were classified in constipated patients and healthy people. Objective visualization of the large intestine was used to assess constipation. Therefore, fecal retention among adults and elderly individuals was reported using ultrasonography. It was suggested that stool retention could be confirmed by observing the hyperechoic region of the rectum. Strong hyperechoic regions with acoustic shadows in the rectum indicate the presence of hard stools, thus enabling medical workers to identify constipation. In the future, ultrasonography may be useful for diagnosing IBS in unconscious patients or those with cognitive decline.

Abstract
BACKGROUND The aetiology of irritable bowel syndrome (IBS) is multifactorial, including genetic and environmental factors. Previous studies have suggested that low birth weight and family environment during childhood are associated with developing IBS. METHODS A survey was sent to all individuals in a UK twin registry. Questions included IBS diagnosed by the Rome IV criteria and if a doctor had previously diagnosed them with IBS. Subjects were categorized as having IBS by Rome IV criteria, a medical diagnosis of IBS or no IBS. Further questions included subjects' recollections of their parents' responses to illness in both the respondent as a child and in the parents themselves. Information regarding birth weight and gestational age have been collected previously. KEY RESULTS 4258 subjects responded to the questionnaire (51.7%), mean age of 52 (SD 14) years, of whom 98.5% were white and 89.6% female. The mean birth weight was 2.4 (0.6) kg. 5.1% satisfied the Rome IV IBS criteria, the same prevalence as the UK population. However, 14.1% had a previous medical diagnosis of IBS. There was no association found between birth weight and IBS or a medical diagnosis of IBS. On multivariable regression analysis, including parental responses to illness, subjects recalling a parent responding to the parent's bowel symptoms by excusing themselves from household chores were associated with a Rome IV diagnosis of IBS (OR 2.19 (95% CI 1.17-4.10), P = .013). CONCLUSIONS AND INFERENCES There was no association between birth weight and IBS. However, observing their parents excuse themselves from household chores when they had bowel symptoms was associated with IBS in later life.

Abstract
A large amount of interindividual variability exists in symptom experiences of persons with irritable bowel syndrome (IBS). Thus, consideration of multiple symptoms to identify distinct symptom subgroups may be useful in directing personalized health strategies for symptom management. We aimed to identify latent classes (i.e., subgroups) of persons with IBS who share similar patterns of symptoms using symptom-related variables (six groups of daily diary symptoms, cognitive beliefs about IBS, and IBS quality of life [QOL]); and to examine how subgroups differed in patient characteristics. Data were derived from a baseline assessment of men and women enrolled in two cognitively-focused intervention trials (N = 332). Using latent class analysis, four latent classes were identified: Class 1 (low symptoms and good QOL, n = 153), Class 2 (low symptoms and moderate QOL, n = 106), Class 3 (high symptoms with diarrhea and poor QOL, n = 38), and Class 4 (high symptoms with low diarrhea and moderate QOL, n = 35). Diarrhea, being female, less formal education, unemployment, and previous history of major depressive disorder were associated with membership in Class 3. Using these distinct symptom profiles, the next step is to explore underlying mechanisms accounting for symptom burden with the goal of designing tailored interventions to reduce that burden.

Abstract
BACKGROUND Visceral hypersensitivity in irritable bowel syndrome (IBS), measured with rectal balloon distensions, using a barostat, has been suggested to be a phenomenon that is reduced due to habituation at repeated investigations. We investigated the stability of rectal sensitivity in patients with IBS who had undergone a previous rectal barostat study and assessed variations in symptom pattern and severity in relation to rectal sensory function. METHOD Irritable bowel syndrome patients, who had previously been undergone a rectal barostat study, were included. All patients underwent a second study 8-12 years later. Symptoms were characterized by use of questionnaires. KEY RESULTS We included 26 subjects (17 females, median age at the index investigation 44.5 (21-61) years). Pressure and volume sensory thresholds were unchanged at the follow-up compared with the index investigation (P > 0.05 for all). At the index investigation, 8/26 patients had rectal hypersensitivity of which four were reclassified as normosensitive, and sixfrom normo- to hypersensitive, meaning that 10/26 patients were hypersensitive at the follow-up investigation. IBS-QOL had improved significantly in six of nine domains at follow-up (P < 0.05 for all). There were no differences in anxiety, depression, IBS symptom severity, or somatization (P > 0.05) at follow-up. None of these were associated with change in rectal sensitivity at follow-up. CONCLUSIONS AND INFERENCES Rectal hypersensitivity and IBS symptoms remained stable at the group level over 8-12 years in IBS patients, even though individual fluctuations were noted. Our findings contradict previous findings indicating that visceral hypersensitivity is an unstable trait.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a common and potential disabling functional gastrointestinal disorder. Studies have revealed a possible association between IBS and psychological problems, such as anxiety and depression. Existing systematic reviews have addressed only the levels of anxiety or depression in patients with IBS. AIM To investigate systematically the prevalence of anxiety or depression in IBS patients METHODS: A literature search was conducted using the related keywords from the bibliographic databases of Embase, PubMed, Scopus, Web of Science and POPLINE published until 1 January 2019 with no language restriction. Studies reporting the prevalence of anxiety/depressive symptoms/disorders in adult (≥15 years) IBS patients were evaluated. The pooled prevalence, odds ratio (OR) and 95% CI were calculated using stata software. RESULTS A total of 14 926 articles were initially screened, and finally 73 papers were included. The prevalence rates of anxiety symptoms and disorders in IBS patients were 39.1% (95% CI: 32.4-45.8) and 23% (95% CI: 17.2-28.8) respectively. The ORs for anxiety symptoms and disorders in IBS patients compared with healthy subjects were 3.11 (95% CI: 2.43-3.98) and 2.52 (95% CI: 1.99-3.20) respectively. The prevalence estimates of depressive symptoms and disorders in IBS patients were 28.8% (95% CI: 23.6-34) and 23.3% (95% CI: 17.2-29.4) respectively. The ORs for depressive symptoms and disorders in IBS patients compared to healthy subjects were 3.04 (95% CI: 2.37-3.91) and 2.72 (95% CI: 2.45-3.02) respectively. CONCLUSION Patients with IBS have a three-fold increased odds of either anxiety or depression, compared to healthy subjects.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) can be responsible for alteration in quality of life and economic burden. The aim of this study was to evaluate healthcare use related to this disorder in France. METHODS The French health data system was used to select adults covered by the general health scheme (87% of population) through their first IBS hospitalization in 2015. We studied the healthcare refunded during the previous 5 years, 1 year before and after hospitalization. RESULTS Among 43.7 million adults who used refunded healthcare in 2015, 29,509 patients were identified (0.07, 33% males, 67% females, mean age 52 years, 30% admitted through emergency room). During their hospitalization, 33% had upper endoscopy and 64% colonoscopy. Over the five previous years, 3% had at least one hospitalization with an IBS diagnosis, 58% had abdominal ultrasonography, 27% CT scan, 21% upper endoscopy, 13% colonoscopy and 83% a gastroenterologist visit. The year before, these rates were respectively: 0, 36, 16, 6, 4 and 78%. Some of those rates decreased the year after the hospitalization with respectively: 1, 27, 13, 5, 4 and 19%. The year before, 65% had at least one CRP dosage (13% three or more), 58% a TSH dosage (7%) and 8% a test for coeliac diseases (1%) and the year after: 44% (8%), 43% (5%) and 3% (0.3%). At least one refund of a drug used to treat IBS was found for 85% of patients 5 years before, 65% one year before and 51% one year after. CONCLUSION This first study using French health data system for healthcare consumption assessment in IBS points out the repetition of outpatient visits, examinations and in particular radiological examinations, without a strong decrease after hospitalization for IBS and gastroenterologist visit.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterised by abdominal pain and altered bowel movements. Cognitive behavioural therapy (CBT) has been shown to be effective in reducing symptom severity in IBS and enhancing quality of life/functioning. The present study sought to identify how CBT achieves change in these outcomes. METHOD Secondary analysis was conducted on 149 patients with irritable bowel syndrome who had been randomised to cognitive behavioural therapy plus an antispasmodic medication or antispasmodic alone. Single and sequential mediation was modelled using structural equation modelling. Gastrointestinal (GI) related avoidance behaviour, safety behaviour, cognitions and general anxiety were included as mediators. RESULTS GI safety behaviours, cognitions and general anxiety mediated treatment effect on the outcomes of symptom severity and work and social adjustment. Avoidance behaviour was not a significant mediator for either outcome. Sequential mediation models indicated that unhelpful GI related cognitions reduced before anxiety did, and this sequential path (R➔GI related cognitions➔anxiety➔outcome) was significant for both symptom severity (b = -0.22, CI [-0.40 to -0.90], p = .005) and work and social adjustment (b = -0.26, CI [-0.44 to -0.11], p = .003) where 'R' is randomisation. Reduction in GI safety behaviours also preceded reduction in anxiety. This sequence (R ➔GI safety behaviours➔anxiety➔outcome) was significant for both symptom severity (b = -0.11, CI [-0.24 to -0.01], p = .049) and work and social adjustment (b = -0.12, CI [-0.23 to -0.03], p = .03). CONCLUSION Results suggest that it is important for psychological treatments to target IBS specific factors for change.

Abstract
BACKGROUND Recent studies indicate that gut microbiota disorders potentially contribute to the pathogenesis of irritable bowel syndrome (IBS), which can be partly reflected by fecal short-chain fatty acids (SCFAs) generated from gut microbiota. Previous studies on SCFA alterations in patients with IBS have yielded conflicting results. No prior systematic review has been conducted on the alterations in fecal SCFAs in IBS patients. AIMS We performed a meta-analysis to explore and clarify alterations in fecal SCFAs in IBS patients. METHODS Case-control studies, randomized controlled trials (RCTs), and self-controlled studies were identified through electronic database searches. The standardized mean difference (SMD) with 95% confidence interval (CI) in fecal SCFA levels between different groups was calculated. RESULTS The proportion of fecal propionate in patients with IBS was significantly higher than in healthy controls (HCs) (SMD = 0.44, 95% CI = 0.12, 0.76). A subgroup analysis showed that the concentration of fecal propionate (SMD = -0.91, 95% CI = -1.41, -0.41) and butyrate (SMD = -0.53, 95% CI = -1.01, -0.04) in patients with constipation-predominant IBS (IBS-C) was significantly lower than that in HCs, and the concentration of fecal butyrate in patients with diarrhea-predominant IBS (IBS-D) was higher than that in HCs (SMD = 0.34, 95% CI = 0.00, 0.67). Finally, we found that restricted diets correlated with fecal butyrate reduction in IBS (SMD = -0.26, 95% CI = -0.51, -0.01). CONCLUSIONS In terms of fecal SCFAs, there were differences between patients with IBS and HCs. In IBS-C patients, propionate and butyrate were reduced, whereas butyrate was increased in IBS-D patients in comparison to HCs. Propionate and butyrate could be used as biomarkers for IBS diagnosis.

Abstract
BACKGROUND Data-driven population segmentation analysis utilizes data analytics to divide a heterogeneous population into parsimonious and relatively homogenous groups with similar healthcare characteristics. It is a promising patient-centric analysis that enables effective integrated healthcare interventions specific for each segment. Although widely applied, there is no systematic review on the clinical application of data-driven population segmentation analysis. METHODS We carried out a systematic literature search using PubMed, Embase and Web of Science following PRISMA criteria. We included English peer-reviewed articles that applied data-driven population segmentation analysis on empirical health data. We summarized the clinical settings in which segmentation analysis was applied, compared and contrasted strengths, limitations, and practical considerations of different segmentation methods, and assessed the segmentation outcome of all included studies. The studies were assessed by two independent reviewers. RESULTS We retrieved 14,514 articles and included 216 articles. Data-driven population segmentation analysis was widely used in different clinical contexts. 163 studies examined the general population while 53 focused on specific population with certain diseases or conditions, including psychological, oncological, respiratory, cardiovascular, and gastrointestinal conditions. Variables used for segmentation in the studies are heterogeneous. Most studies (n = 170) utilized secondary data in community settings (n = 185). The most common segmentation method was latent class/profile/transition/growth analysis (n = 96) followed by K-means cluster analysis (n = 60) and hierarchical analysis (n = 50), each having its advantages, disadvantages, and practical considerations. We also identified key criteria to evaluate a segmentation framework: internal validity, external validity, identifiability/interpretability, substantiality, stability, actionability/accessibility, and parsimony. CONCLUSIONS Data-driven population segmentation has been widely applied and holds great potential in managing population health. The evaluations of segmentation outcome require the interplay of data analytics and subject matter expertise. The optimal framework for segmentation requires further research.

Int J Biol Sci 2018; 14:1504-1512. [PMID: 30263003 PMCID: PMC6158731 DOI: 10.7150/ijbs.25001] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Accepted: 05/13/2018] [Indexed: 12/15/2022] Open
Abstract
Depression is common in patients with irritable bowel syndrome (IBS), but the reported prevalence across different studies is inconsistent. This meta-analysis systematically examined the presence and severity of depressive symptoms in patients with IBS. Two investigators independently performed a literature search. The pooled depressive symptom severity was calculated using a random effects model. Subgroup, sensitivity and meta-regression analyses were conducted to examine the moderating factors of the development of depressive symptoms. Twenty four studies (n=2,837) comparing depressive symptoms between IBS patients (n=1,775) and healthy controls (n=1,062) were identified; 14 (58.3%) studies were rated as high quality. Compared to healthy controls, IBS patients had more frequent (OR=9.21, 95%CI: 4.56-18.57, P<0.001; I2=76%) and more severe depressive symptoms (n=1,480, SMD=2.02, 95%CI: 1.56-2.48, P<0.001; I2=94%). Subgroup analyses revealed that patients with all IBS subtypes had more severe depressive symptoms than controls. In addition, versions of the Hamilton Depression Rating Scale (HAM-D) and IBS diagnostic criteria were significantly associated with depressive symptom severity. Meta-regression analyses revealed that female gender, younger age and small sample size were significantly associated with more severe depressive symptoms. In conclusion, meta-analytic data showed that IBS patients had more frequent and severe depressive symptoms than healthy controls. Adequate screening and treatment for depression should be developed and implemented in this patient population.

Abstract
Lapatinib and capecitabine have been widely used in the therapy of breast cancer. However, long-term use of lapatinib and capecitabine often causes the most common side effect diarrhea, which limit the medicine use. Fructus mume (F. mume) has been proved to be effective to treat chronic diarrhea with few side effects. The compounds from F. mume were extracted by using an ethanol method. Extracts of F. mume (EFM) were analyzed by HPLC. We investigated the protective effects of EFM on the diarrhea caused by lapatinib and capecitabine. From March 1st, 2016 to June 1st, 2017, 208 breast cancer patients with diarrhea caused by lapatinib and capecitabine were recruited. The patients were evenly assigned into two groups: EG group (the patients took 100 mg EFM daily) and CG group (the patients took placebo daily). The effects of EFM on diarrhea and gastrointestinal symptoms were measured by a semiquantitative method seven-point Likert scale. Overall quality of life was measured by SF-36 questionnaire and Hospital Anxiety and Depression Scale (HADS). The HPLC analysis showed that there were three components in EFM, including citric acid, 5-hydroxymethylfurfural (5-HMF), and chlorogenic acid. Breast cancer types were observed by using Hematoxylin and eosin (H&E) stain. The breast cancer can be divided into leaflet, gland and fibroblast types. Patient age, skin metastases, treatment, and grade 1 diarrhea were significant risk factors associated with for grade 2 diarrhea. EFM reduced diarrhea and gastrointestinal symptoms by reducing the average scores of the diarrhea symptom and seven-point Likert scale, and improved life quality of patients significantly by improving SF-36 scores and reducing HADS scores when compared to that in the CG group after 6-week therapy and further 4-week follow-up (P < 0.05). EFM may be a potential choice for the diarrhea therapy in breast cancer patients.

Abstract
Objectives: This study compared the physical, mental, and social health levels among Organization for Economic Co-operation and Development countries. Methods: We sampled from 34 Organization for Economic Co-operation and Development member countries and divided physical, mental, and social health into three domains based on World Health Organization health definitions. Results: A multivariate hierarchical cluster analysis was conducted to group countries that were similar in terms of health. Regarding physical health, Japan, South Korea, Sweden, Switzerland, and ten more countries reported favorable health conditions. For mental health, Australia, Canada and eight more countries revealed favorable conditions. Finally, in terms of social health, Austria, Finland, Iceland, and seven more countries reported favorable conditions. Sweden and Switzerland reported the best health conditions aggregated across all three domains. Conversely, Estonia, Hungary, and Turkey reported comparatively poorer health across all three domains when compared with other Organization for Economic Co-operation and Development countries. Conclusions: We suggested that mental health policy should be further strengthened in cases of Korea and Japan. In case of the Eastern Bloc countries, health policies should be established focusing on health equity for effective improvement of indicators.

Alexithymia and anesthetic bladder capacity in interstitial cystitis/bladder pain syndrome. J Psychosom Res 2017; 100:15-21.

Abstract
OBJECTIVE In contrast to the inconsistent results of organic causes, it has been found that psychological risk factors are reliably related to functional somatic syndromes (FSSs), including interstitial cystitis/bladder pain syndrome (IC/BPS). Compared to patients with acute cystitis, a subgroup of IC/BPS patients with a history of childhood relational trauma reported intensified unregulated affective states (i.e., anxiety and depression) and trauma-related psychopathology (i.e., dissociation). Nevertheless, it remains unknown whether psychosocial risk factors can be separated from bladder-centric factors. This study aimed to verify whether psychosocial factors such as alexithymia, which is a key psychological factor of FSSs, are less likely to be linked to a low bladder capacity in patients with IC/BPS. METHODS Ninety-four female IC/BPS patients were recruited from the outpatient departments of urology, obstetrics, and gynecology. Anxiety, depression, dissociation, childhood relational trauma, and alexithymia were assessed using standardized scales, and anesthetic bladder capacity was examined by cystoscopic hydrodistention. RESULTS Positive correlations were found between anesthetic bladder capacity and the psychosocial variables, including alexithymia. An increased bladder capacity was associated with anxiety, dissociation, and childhood relational trauma, and a combination of high cognitive and low affective alexithymia mediated the correlations between bladder capacity and the psychosocial variables. CONCLUSIONS Psychosocial variables that are associated with an aversive childhood relational environment and affect dysregulation may constitute a pathogenic trajectory that differs from bladder-centric defects such as a lower bladder capacity. The findings of this study support the notion that IC/BPS in some patients may be due to an FSS.

Abstract
BACKGROUND AND OBJECTIVES The majority of patients with irritable bowel syndrome (IBS) are diagnosed and treated in primary care. The aim of this study was to investigate the implementation of the Rome criteria in daily primary care clinical practice and adherence of general practitioners (GPs) to recommended diagnostic approaches for IBS. PATIENTS AND METHODS A survey consisting of 18 questions was distributed across 11 European countries and was used to assess GPs' diagnostic approach of IBS, the use of Rome criteria in daily practice and GPs' perspective on the aetiology of the disorder. RESULTS Overall, 185 GPs completed the survey. In daily clinical practice, 32% of GPs reported that they usually make a positive diagnosis on the basis of symptoms only, whereas 36% of GPs reported regular use of the Rome criteria to diagnose IBS. Furthermore, 62% of the responders reported that they applied additional diagnostics, such as blood tests, 31% found it necessary to perform endoscopy to make a positive diagnosis of IBS and 29% referred patients with IBS to a specialist. Psychological factors were the most frequently selected potential aetiological factor of IBS (88% of GPs). Overall, 52% of GPs reported systematically including questions on psychological symptoms in the assessment of history of IBS. CONCLUSION Only about one-third of GPs regularly used the Rome criteria to diagnose IBS. In daily primary care practice, IBS largely remains a diagnosis of exclusion. This has implications in terms of GPs' specialty training and questions the applicability of IBS guidelines in daily care, which advocate an early, positive, symptom-based diagnosis.

Abstract
OBJECTIVE The individual occurrence of depression or insomnia is a risk factor for irritable bowel syndrome (IBS), but few researchers have evaluated the association between comorbid depression and insomnia and IBS. The aim of the present study is to explore the relationship between IBS and the coexistence of depression and insomnia in a Korean population-based cohort study. METHODS A total of 3429 individuals who were enrolled in the Korean Genome and Epidemiology Study were analysed. Of the participants, 10.9% (n=374) were diagnosed with IBS based on the Rome II criteria. Regarding depressive symptoms, subjects were sub-divided into three groups based on the Beck Depression Inventory (BDI) score. Insomnia was defined as a positive response to at least one of three questions on sleep states. RESULTS The odds ratio (OR) of IBS increased proportionally as depressive symptoms worsened (OR: 1.64; 95% CI: 1.21-2.23 in middle tertile and OR: 2.61; 95% CI: 1.92-3.55 in highest tertile). Subjects with insomnia showed a higher OR of IBS than those without insomnia (OR: 1.81; 95% CI: 1.44-2.27). In the joint analysis of BDI and insomnia, the odds for IBS were significantly higher in all BDI tertiles with insomnia than in the corresponding BDI tertiles without insomnia. There was no significant interaction effect of BDI tertile and insomnia on IBS. CONCLUSION The presence of both depression and insomnia is significantly associated with IBS compared to each individual occurrence. Further prospective investigations are needed to explore possible causality between comorbid depression and insomnia and IBS.

Abstract
Background: Psychiatric disorders are common in irritable bowel syndrome (IBS). We conducted this study to investigate the relationship of IBS and their subtypes with some of psychological factors. Materials and Methods: A cross-sectional study was performed among 4763 staff of Isfahan University of Medical Sciences in 2011. Modified ROME III questionnaire and Talley Bowel Disease Questionnaire were used to evaluate IBS symptoms. Hospital Anxiety and Depression Scale and 12-item General Health Questionnaire were utilized to assess anxiety, depression and psychological distress. Logistic regression analysis was used to determine the association of psychological states and IBS in the total subject and both genders. Results: About, 4763 participants with mean age 36/58 ± 8/09 were included the 2106 males and 2657 females. Three thousand and seven hundred and seventy-six (81.2%) and 2650 (57.2%) participants were married and graduated respectively. Subtype analysis of IBS and its relationship with anxiety, depression and distress comparing the two genders can be observed that: IBS and clinically-significant IBS have higher anxiety, depression symptoms, and distress than the subject without IBS (P < 0.001). Women with IBS, have higher scores than men (P < 0.001). Compared to other subtypes, mixed IBS subtype has a higher anxiety, depression, and distress score. Conclusion: A high prevalence of anxiety, depression symptoms and distress in our subjects emphasize the importance of the psychological evaluation of the patients with IBS, in order to better management of the patients and may also help to reduce the burden of health care costs.

Abstract
OBJECTIVE The aims of the study were to define the heterogeneity of vulvodynia by determining data-driven subgroups within the vulvodynia diagnosis using exploratory cluster analysis and to characterize the subgroups identified. MATERIALS AND METHODS Included were participants in the longitudinal population-based study of vulvodynia in southeast Michigan who screened positive for vulvodynia at least once during the study. A cluster analysis using variables reflecting vulvar pain characteristics and comorbid pain conditions was conducted. Variables reflecting best separation of clusters were used to assign participants to subgroup categories. Demographic, psychiatric, general health, and other vulvar pain characteristics were summarized for each subgroup, followed by multinomial regression and pairwise comparisons of subgroups on these factors. RESULTS Of 441 women screening positive for vulvodynia during the course of the study, 393 were eligible on the basis of data requirements. Cluster analysis suggested that best subgroup separation was based on the following 2 variables: (1) presence or absence of spontaneous vulvar pain and (2) presence or absence of other comorbid pain conditions. Subgroups did not differ by age or ethnicity. The subgroup having spontaneous pain and other comorbid conditions demonstrated greatest morbidity in general health measures, psychiatric disorders, and other vulvar pain measures. Primary versus secondary vulvodynia did not vary between subgroups and did not assist in subgroup separation in the cluster analysis. DISCUSSION Subgroups based on exploratory cluster analysis demonstrated that presence of spontaneous pain and the presence of comorbid pain conditions resulted in best separation of groups. Presence of both spontaneous pain and other comorbid pain conditions identified the group with greatest morbidity.

Abstract
The review focuses on those personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness), constructs (alexithymia and distressed - Type D personality) and emotional patterns (negative and positive) that are of particular concern in health psychology, with the aim to highlight their potential role on the pathogenesis, onset, symptom clusters, clinical course, and outcome of irritable bowel syndrome (IBS). Personality traits and emotional patterns play key roles in affecting autonomic, immune, inflammatory, and endocrine functions, thus contributing not only to IBS clinical expression and symptomatic burden, but also to disease physiopathology. In this sense, psychological treatments should address those personality traits and emotional features that are constitutive of, and integral to IBS. The biopsychosocial model of illness applied to IBS acknowledges the interaction between biological, psychological, environmental, and social factors in relation to pain and functional disability. A holistic approach to IBS should take into account the heterogeneous nature of the disorder, and differentiate treatments for different types of IBS, also considering the marked individual differences in prevalent personality traits and emotional patterns. Beyond medications, and lifestyle/dietary interventions, psychological and educational treatments may provide the optimal chance of addressing clinical symptoms, comorbid conditions, and quality of life in IBS patients.

Abstract
Functional gastrointestinal disorders have been related with different psychological conditions. On the contrary, the role of psychological factors within gastrointestinal motor disorders remains unclear. The objective of this study was to explore the differences and congruence with clinical performance of the psychological profile and subjective functionality among patients diagnosed with functional gastrointestinal disorders and gastrointestinal motor disorders. Using a double-blind design, 56 inpatients from a Gastroenterology Department were included in the study. No major differences were detected between the two groups. However, clinical performance was coherent with subjective physical functioning only among patients diagnosed with gastrointestinal motor disorders. These results may provide useful information for gastroenterologists dealing with patients' complaints not consistent with their clinical profile.

Abstract
Type 2 diabetes is growing worldwide due to population growth, increased rates of obesity, unhealthy diet, and physical inactivity. Risk assessment methods can effectively evaluate the risk of diabetes, and a healthy lifestyle can significantly reduce risk or prevent complications of type 2 diabetes. However, risk assessment alone has not significantly improved poor adherence to recommended medical interventions and lifestyle changes. This paper focuses on the challenge of nonadherence and posits that improving adherence requires tailoring interventions that explicitly consider the social determinants of health.

Abstract
Irritable bowel syndrome (IBS) is regarded as a multifactorial disease in which alterations in the brain-gut axis signaling play a major role. The biopsychosocial model applied to the understanding of IBS pathophysiology assumes that psychosocial factors, interacting with peripheral/central neuroendocrine and immune changes, may induce symptoms of IBS, modulate symptom severity, influence illness experience and quality of life, and affect outcome. The present review focuses on the role of negative affects, including depression, anxiety, and anger, on pathogenesis and clinical expression of IBS. The potential role of the autonomic nervous system, stress-hormone system, and immune system in the pathophysiology of both negative affects and IBS are taken into account. Psychiatric comorbidity and subclinical variations in levels of depression, anxiety, and anger are further discussed in relation to the main pathophysiological and symptomatic correlates of IBS, such as sensorimotor functions, gut microbiota, inflammation/immunity, and symptom reporting.

Our aim was to investigate similarities and differences among nonpainful CC, painful CC, and CC in patients with IBS according to prevalence, individual symptoms, associated factors, and impact on health-related quality of life and use of medical resources. METHODS We conducted a telephone survey of a random sample of the Spanish population (N=1500). Bowel symptoms were recorded using the Rome III questionnaire, health-related quality of life using the short form-12 (SF-12) and quality of live in constipation-20 (CVE-20) questionnaires, and self-reported constipation, lifestyle habits, and consultation behavior using an ad hoc questionnaire. RESULTS The overall prevalence of CC was 19.2%, with prevalence by subgroups being 13.9% for nonpainful CC, 2.0% for painful CC, and 3.3% for CC in patients with IBS. CC was more prevalent among women at a ratio of 2.7:1. Subjects with painful CC and CC in patients with IBS were younger, reported more constipation, and had more symptoms than subjects with nonpainful CC. Age and physical activity were significantly associated with CC. Symptoms associated with consultation were abdominal pain and digitation. Nonpainful CC patients were more satisfied with laxative use than were the other subgroups. Subjects with CC showed a significant impairment in the physical and mental component of the SF-12 questionnaire. CONCLUSIONS CC appears to be a spectrum; most patients do not have abdominal pain/discomfort but others (with otherwise quite similar characteristics) are patients with IBS or are out of any established diagnosis.

Abstract
Stress can lead to the manifestation of functional gastrointestinal disorders, the most prominent being irritable bowel disorder. The present study investigated the impact zingerone in ameliorating chronic water stress induced irritable bowel disorder, brain gut axis dysfunction and dysregulation of the intestinal barrier due to oxidative stress. Rats were randomly allocated to groups and subjected to chronic water stress for a period of 21 days for 1h and the fecal pellet output was measured. At the end of chronic stress, behavioral assessment for anxiety like behavior was recorded and plasma corticosterone levels were measured 60min after water stress. The colonic transit was determined, levels of oxidative and antioxidant biomarkers were measured in the colon homogenate. Myeloperoxidase activity was determined as an indirect index of neutrophil infiltration. Chronic water stress increased the rate of colonic transit, fecal output, induced behavioral changes, and decreased antioxidant levels. An increase in lipid peroxide levels, catalase and corticosterone was observed. Mast cell infiltration was evident in the stressed group. Zingerone significantly reduced colonic transit, fecal output, neutrophil infiltration, and lipid peroxide formation. The levels of catalase were not altered; however, a marginal increase in the levels of glutathione peroxidase was observed. Zingerone significantly enhanced the levels of superoxide dismutase, glutathione and decreased the levels of corticosterone. Zingerone produced marked improvement in stress induced irritable bowel disorder which could be attributed to the powerful antioxidant nature, direct effect on the intestinal smooth muscle and adaptogenic nature.

Abstract
Background Psychiatric disorders are common in irritable bowel syndrome (IBS) patients. The prevalence of psychiatric disorders in IBS patients varies in different cultures. We conducted this study to determine the prevalence of psychiatric disorders Methods In a cross-sectional study, 256 IBS patients were selected (using the criteria of Rome III) and evaluated for psychiatric disorders. In the first phase, subjects were screened using the General Health Questionnaire 28 (GHQ28). In the second phase, those who had scores ≥ 23 were assessed through semi-structured psychiatric interviews. Results Thirty out of 256 subjects had no significant psychiatric symptoms after performing GHQ28. In further psychiatric evaluation of the remaining subjects (226) who suffered from some degree of a psychiatric problem, 36 were diagnosed without Anxiety/Depressive disorder. Thus 66 subjects (25.8%) were known as a group without any significant psychiatric problem. A total of 190 subjects (74.2%) with anxiety-depressive problems were diagnosed; 89 were suffering from pure anxiety disorders, 41 were suffering from depressive disorders and 60 had co-morbid anxiety-depressive disorders. When comparing anxiety-depressive patients (n = 190) with normal subjects (n = 66), gender (P = 0.016), occupation (P = 0.002) and intensity of IBS (P < 0.001) showed statistically significant differences. Conclusion The high prevalence of anxiety-depressive disorders in this study indicates the necessity of psychiatric assessment, early diagnosis and treatment of the patients with IBS. It may improve management of the patients suffering from IBS.

Abstract
Functional gastrointestinal disorder (FGID) is one of the commonest digestive diseases worldwide and leads to significant morbidity and burden on healthcare resource. The putative bio-psycho-social pathophysiological model for FGID underscores the importance of psychological distress in the pathogenesis of FGID. Concomitant psychological disorders, notably anxiety and depressive disorders, are strongly associated with FGID and these psychological co-morbidities correlate with severity of FGID symptoms. Early life adversity such as sexual and physical abuse is more commonly reported in patients with FGID. There is mounting evidence showing that psychological disorders are commonly associated with abnormal central processing of visceral noxious stimuli. The possible causal link between psychological disorders and FGID involves functional abnormalities in various components of the brain-gut axis, which include hypothalamic-pituitary-adrenal system, sympathetic and parasympathetic nervous system, serotonergic and endocannabinoid systems. Moreover, recent studies have also shown that psychological distress may alter the systemic and gut immunity, which is increasingly recognized as a pathophysiologic feature of FGID. Psychotropic agent, in particular antidepressant, and psychological intervention such as cognitive behavioral therapy and meditation have been reported to be effective for alleviation of gastrointestinal symptoms and quality of life in FGID patients. Further studies are needed to evaluate the impact of early detection and management of co-morbid psychological disorders on the long-term clinical outcome and disease course of FGID.

Abstract
OBJECTIVE Gastric sensitivity testing relies on subjective reporting and may therefore be influenced by psychosocial factors and somatization. Furthermore, psychological processes may affect gastric motor function (accommodation to a meal emptying) through efferent brain-gut pathways. This study sought to determine the association of abuse history, psychiatric comorbidity, and somatization with gastric sensorimotor function. METHODS In 201 patients with functional dyspepsia, gastric sensitivity and accommodation were studied with a barostat. Gastric emptying of solids was studied using a breath test. Sexual and physical abuse history, psychiatric comorbidity (depression and panic disorder), and somatization were assessed using validated questionnaires. Multiple linear regression models were used to identify patient characteristics independently associated with gastric sensitivity and emptying. RESULTS Age (p = .02), sexual abuse history (p < .001), physical abuse history (p = .004), and somatization (p < .001) were independently associated with gastric discomfort threshold (R(2) = 0.30); a significant depression-by-sexual abuse interaction effect was also found (p = .003). None of the factors studied were associated with gastric accommodation to a meal. Physical abuse history (p = .003) and somatization (p = .048) were independently associated with gastric emptying (R(2) = 0.19). CONCLUSIONS These results demonstrate the complex relationship among abuse history, psychiatric comorbidity, somatization, and gastric sensorimotor (dys)function. Although the psychobiological mechanisms underlying these relationships remain to be determined, the autonomic nervous, stress hormone, and immune systems may be involved.

Abstract
GOALS AND BACKGROUND Patients with irritable bowel syndrome (IBS) have significantly impaired quality of life (QoL). We investigated the presence of dysfunctional cognitions, anxiety, and depression symptoms and their impact on daily symptoms and QoL in a large IBS cohort. STUDY A total of 268 IBS patients (Rome II criteria, age 18 to 65 y) were included. Patients completed a 2-week daily symptom diary. The Short Form-36 was used to score QoL. The 31-items Cognitive Scale for Functional Bowel Disorders (CSFBD) and the Hospital Anxiety and Depression Scale (HADS) were used to analyze the psychological factors. RESULTS Possible anxiety and depression disorders were present in 30% and 22% of IBS patients, respectively. Patients with anxiety and depression had significantly higher mean symptom scores, impaired QoL, and higher CSFBD scores (P<0.01). Physical and mental QoL were both affected by depression (HADS-D) and dysfunctional cognitions (P<0.01). Only physical QoL, not mental QoL, was affected by referral type (hospital setting vs. community based; P<0.01). Only mental QoL was affected by anxiety (HADS-A) (P<0.01). Dysfunctional cognitions independently of anxiety and depression influenced QoL and IBS symptoms. CONCLUSIONS In this IBS cohort, dysfunctional cognitions independently influence physical and mental QoL and symptom severity. Presence of possible anxiety and depression disorders resulted in higher symptoms, lower QoL, and higher CSFBD scores. The results point toward an important role of psychological factors, especially dysfunctional cognitions on QoL and symptom scores in IBS patients.

Abstract
BACKGROUND Anxiety, depression and nongastrointestinal symptoms are often prominent in irritable bowel syndrome (IBS), but their relative value in patient management has not been quantitatively assessed. We modified the Patient Health Questionnaire 15 (PHQ-15) by excluding three gastrointestinal items to create the PHQ-12 Somatic Symptom (PHQ-12 SS) scale. AIMS To compare the value of the PHQ-12 SS scale with the Hospital Anxiety and Depression (HAD) scale in predicting symptoms and patient behaviour in IBS and diverticular disease. METHODS We compared 151 healthy volunteers (HV), 319 IBS patients and 296 patients with diverticular disease (DD), 113 asymptomatic [ASYMPDD] and 173 symptomatic DD (SYMPDD). RESULTS Patient Health Questionnaire 12 SS scores for IBS and SYMPDD were significantly higher than HV. Receiver-operator curves showed a PHQ-12 SS >6, gave a sensitivity for IBS of 66.4% with a specificity of 94.7% and a positive likelihood ratio (PLR) = 13.2, significantly better than that associated with an HAD anxiety score >7, PLR = 3.0 and depression score >7 PLR = 6.5. PHQ-12 SS correlated strongly with IBS severity scale and GP visits in both IBS and DD. CONCLUSION The PHQ-12 SS scale is a useful clinical tool which correlates with patient behaviour in both IBS and symptomatic DD.

Abstract
The present study aimed to elucidate the differences in depression, anxiety, anger, and quality of life in a sample of non-psychiatric IBS patients, starting from the hypothesis that IBS subtypes may have different symptomatic expressions of negative emotions with different outcomes on quality of life measures. Forty-two constipation-predominant IBS (C-IBS) subjects and 44 diarrhea-predominant IBS (D-IBS) subjects, after an examination by a gastroenterologist and a total colonoscopy, underwent a clinical interview and psychometric examination for the assessment of depression, anxiety, anger and quality of life. IBS subtypes showed different symptomatic profiles in depression, anxiety and anger, with C-IBS patients more psychologically distressed than D-IBS subjects. Affective and emotional symptoms should be considered as specific and integral to the syndrome, and recognizing the differences between IBS subtypes may have relevant implications for treatment options and clinical outcome.

Abstract
Functional gastrointestinal disorders (FGID) are common, but despite their relevance in public health care, the etiology of FGID remains essentially unknown. Stress has been suggested as a pathophysiological factor in FGID. The aims of the present study were (a) to determine the prevalence of FGID in a sample of apparently healthy students, and (b) to determine the association of stress and FGID. The prevalence rates of 21 different FGID were assessed using an internet-based design. Subjective experience of chronic stress, individual coping strategies, and dispositional stress reactivity were measured. A total of 668 subjects provided complete data sets (66% women). About 64.2% reported at least one FGID. Symptoms of FGID were significantly predicted by increased levels of perceived chronic stress, dispositional stress reactivity, and use of maladaptive coping strategies. FGID are common in apparently healthy young individuals. The importance of stress-related factors in individuals suffering from FGID indicates that stress-reducing interventions may be beneficial in these patients.

Abstract
Symptoms consistent with the irritable bowel syndrome are remarkably frequent around the world. Irritable bowel syndrome prevalence ranges from 2.1% to 22%, depending on criteria used. Women are more frequently affected than men, but the reasons remain obscure; irritable bowel syndrome occurs in all age groups but there appears to be a modest decline in prevalence with advancing age again for unknown reasons. The incidence of irritable bowel syndrome per year has been estimated at approximately 1.5% in community subjects; annually only 0.2% of population will be diagnosed with irritable bowel syndrome. The natural history of irritable bowel syndrome is characterized by symptomatic flare ups and by a high rate of transition to other functional gastrointestinal diseases over the long term. Well recognized risk factors for irritable bowel syndrome include psychological distress and gastroenteritis. However, the association of psychological distress in some cases may reflect confounding factors and might be explained at least in part by cytokine production. Familial aggregation of irritable bowel syndrome occurs, and while the environment is key, twin studies generally support a genetic component in irritable bowel syndrome explaining up to 20% of the variability. Prior surgery may increase risk of irritable bowel syndrome. Early childhood trauma may be important; a low birth weight, nasogastric suction at birth, childhood abuse, and low socioeconomic status may carry an increased risk of suffering with irritable bowel syndrome as an adult. The role of diet remains uncertain but under-studied.

Abstract
Reported prevalence rates of irritable bowel syndrome (IBS) are between 8% to 20% in the US general population with an average medical expenditure of US$1.35 billion direct and US$205 million indirect costs. Current pathophysiologic theories are based on abnormalities of both the brain and gut, thus setting a new stage for current and future therapeutic approaches. There are numerous treatment options in IBS acting centrally and peripherally by influencing motility and visceral sensitivity. Clinical evidence is variable; however, newer emerging treatments are being evaluated using better-designed clinical trials. Accurate assessment of IBS drug efficacy is still hampered by heterogeneity of the IBS population. Novel methods such as pharmacogenomics or brain imaging may be helpful in the future to better understand and characterize IBS patient subtypes, and this in turn will lead to more specific and efficient therapeutic options. Patient subpopulation measurement of side effects is also a clinical challenge and further understanding could improve treatment efficacy enhancing the patient compliance.

Abstract
The predictive roles of symptom combination traditionally evaluated in traditional Chinese medicine (TCM) in the treatment of rheumatoid arthritis (RA) were explored. Three hundred and ninety six patients were randomly divided into 197 subjects receiving Western medicine therapy (WM) and 199 subjects receiving TCM therapy (TCM). A complete physical examination and 18 clinical manifestations typically assessed in TCM were recorded before the randomization. The ACR responses were used for efficacy evaluation. ACR20 and 50 responses with WM treatment were higher than in the TCM group. The 18 symptoms in RA could be clustered into 4 symptom combinations with factor analysis, which represent joint symptoms, cold pattern, deficiency pattern and hot pattern in TCM respectively. TCM would be more effective in patients with weak-symptom combination 3 (deficiency pattern in TCM), and WM would be more effective in patients with symptom combination 2 (cold pattern in TCM). Symptom combinations judged with TCM may have influence on the efficacy of therapy in the treatment of RA.

Abstract
OBJECTIVES We used cluster analysis to subdivide a population of injection drug users and identify previously unknown behavioral heterogeneity within that population. METHODS We applied cluster analysis techniques to data collected in a cross-sectional survey of injection drug users in Winnipeg, Manitoba. The clustering variables we used were based on receptive syringe sharing, ethnicity, and types of drugs injected. RESULTS Seven clusters were identified for both male and female injection drug users. Some relationships previously revealed in our study setting, such as the known relationship between Talwin (pentazocine) and Ritalin (methylphenidate) use, injection in hotels, and hepatitis C virus prevalence, were confirmed through our cluster analysis approach. Also, relationships between drug use and infection risk not previously observed in our study setting were identified, an example being a cluster of female crystal methamphetamine users who exhibited high-risk behaviors but an absence or low prevalence of blood-borne pathogens. CONCLUSIONS Cluster analysis was useful in both confirming relationships previously identified and identifying new ones relevant to public health research and interventions.

Abstract
BACKGROUND & AIMS Visceral hypersensitivity is a hallmark of irritable bowel syndrome (IBS), but the relationship with clinical symptoms and psychological factors has not been fully established. We aimed to (1) evaluate these variables in a large cohort of IBS patients, recruited from both hospital and general practice, and in healthy controls and (2) assess which of these factors predicts the occurrence of visceral hypersensitivity in IBS. METHODS Rectal compliance and perception (intensity, perception thresholds; visual analogue scale, 0-100 mm) were assessed by a rectal barostat study (ramp distention) in 101 IBS patients and 40 healthy volunteers. IBS symptom severity was scored by using a 14-day 5-item diary. Anxiety, depression, somatization, vigilance, pain coping, dysfunctional cognitions, psychoneuroticism, and quality of life were assessed with psychometric questionnaires. RESULTS Rectal compliance was significantly reduced in IBS patients compared with controls (P < .01), as were thresholds for pain (27 +/- 15 vs 35 +/- 8 mm Hg; P < .01) and urge (P < .05). Levels of anxiety, depression, neuroticism, somatization, and dysfunctional cognitions were significantly increased in IBS patients versus controls, whereas pain coping and quality of life were significantly worse. Hypersensitivity to rectal distention occurred in 33% of patients and was associated with increased symptom severity (P = .016), but not with demographic characteristics or psychological disturbances. CONCLUSIONS Hypersensitivity to balloon distention occurs in 33% of IBS patients and is predicted by symptom severity but not by psychological or demographic characteristics.
