Rationale, development, and design of the Altering Intake, Managing Symptoms (AIMS) dietary intervention for bowel dysfunction in rectal cancer survivors.

PURPOSE: Bowel dysfunction is a common, persistent long-term effect of treatment for rectal cancer survivors. Survivors often use dietary modifications to maintain bowel control. There are few evidence-based interventions to guide survivors on appropriate diet modifications for bowel symptom management. The purpose of this paper is to describe the development and design of the Altering Intake, Managing Symptoms (AIMS) intervention to support bowel dysfunction management in rectal cancer survivors. METHODS: The AIMS intervention is a ten-session, telephone-based diet behavior change intervention delivered by trained health coaches. It uses dietary recall, participant-completed food and symptom diaries, and health coaching guided by motivational interviewing to promote bowel symptom management and improved diet quality. Based on the Chronic Care Self-Management Model (CCM), the AIMS Intervention is designed to improve self-efficacy and self-management of bowel symptoms by coaching survivors to appropriately modify their diets through goal setting, self-monitoring, and problem-solving. The intervention targets survivors with stage I-III rectosigmoid colon/rectum cancer who are 6 months post-treatment, 21 years and older, and English-speaking. CONCLUSIONS: The design and development process described in this paper provides an overview and underscores the potential of the AIMS intervention to positively impact the quality of long-term survivorship for rectal cancer survivors. An ongoing pilot study will inform the design and development of future multi-site Phase II and III randomized trials.

Pediatric Functional Constipation Gastrointestinal Symptom Profile Compared With Healthy Controls.

OBJECTIVES: Patient-reported outcomes are necessary to evaluate the gastrointestinal symptom profile of patients with functional constipation. Study objectives were to compare the gastrointestinal symptom profile of pediatric patients with functional constipation with matched healthy controls with the Pediatric Quality of Life Inventory Gastrointestinal Symptoms and Gastrointestinal Worry Scales and to establish clinical interpretability in functional constipation through identification of minimal important difference (MID) scores. The secondary objective compared the symptom profile of patients with functional constipation with patients with irritable bowel syndrome (IBS). METHODS: Gastrointestinal Symptoms and Worry Scales were completed in a 9-site study by 116 pediatric patients with functional constipation and 188 parents. Gastrointestinal Symptoms Scales measuring stomach pain, stomach discomfort when eating, food and drink limits, trouble swallowing, heartburn and reflux, nausea and vomiting, gas and bloating, constipation, blood in poop, and diarrhea were administered along with Gastrointestinal Worry Scales. A total of 341 families with healthy children and 43 families with patients with IBS completed the scales. RESULTS: A broad profile of gastrointestinal symptoms and worry were reported by patients with functional constipation in comparison with healthy controls (P < 0.001) with large effect sizes (>0.80) across the majority of symptom domains. Patients with IBS manifested a broader symptom profile than functional constipation, with differences for stomach pain, stomach discomfort when eating, and worry about stomachaches, with similar constipation scores. CONCLUSIONS: Pediatric patients with functional constipation report a broad gastrointestinal symptom profile in comparison with healthy controls and only somewhat fewer symptoms than patients with IBS, highlighting the critical need for more efficacious interventions to achieve healthy functioning.

[Relationship Pattern of Mothers with Functional Constipated Infants]. / Beziehungsmuster bei Müttern von Kleinkindern mit funktioneller Obstipation.

Relationship Pattern of Mothers with Functional Constipated Infants The present article investigates whether or not mothers of infants with functional constipation have a specific relationship pattern. This question is addressed by analyzing the data collected at the day care clinic for infant regulation disorders with appropriate methods like the questionnaire for the assessment of adjustment of mothers with children in infancy (EMKK, Engfer u. Codreanu, 1984) described here. The evaluation of data was performed in two ways: first with regard to the clinical study group of mothers with infants (age range from one to five years) suffering from functional constipation, and then compared to a clinical control group of mothers with infants who are coping with regulation disorders (by definition per Papousek, Schieche, Wurmser, 2010). With this comparison differences between the two groups are made visible and clinical interventions can be deduced accordingly. If the groups do not differ in their pattern described by the EMKK, the possible interventions can be adopted from the well-studied area of regulation disorders. The focus on analyzing the data of mothers with functional constipated infants serves as an important starting point for providing the best possible alignment of clinical intervention.

Prevalence and co-occurrence of upper and lower functional gastrointestinal symptoms in patients eligible for bariatric surgery.

BACKGROUND: Obesity is considered as a risk factor for many functional digestive disorders. The aim of the present study was to evaluate the prevalence and the association of functional digestive symptoms affecting the upper and the lower digestive tract in patients eligible for bariatric surgery. METHODS: Before surgery, 120 consecutive patients with normal upper endoscopy (7.5% males, mean BMI 44 ± 6 m/kg(2)) have filled a standard questionnaire in order to evaluate the presence of depressive symptoms and functional digestive disorders according to the Rome criteria. The major symptoms (esophageal, gastroduodenal, anorectal, and abdominal pain) were coded as dichotomous variables. Data analysis was performed using multivariate logistic regression with a backwards selection procedure adjusted only for the variables that were significant in univariate analysis (p < 0.05). RESULTS: Functional symptoms were present in 89% of the subjects (2.5 functional digestive symptoms/subject). Depression symptoms were found in 43% of the patients. Esophageal symptoms were independent predictors for the presence of gastric, bowel, and anorectal symptoms. Functional abdominal pain and bowel symptoms were present, respectively, in 19% and 84% of the patients. Approximately half of the patients have specific functional bowel disorders (28.6% constipation, 18% irritable bowel syndrome, 18% diarrhea, 1% bloating) and 35.7% have non-specific bowel disorders. Anorectal symptoms were found in 40% of the patients: difficult defecation in 32% and fecal incontinence in 9.8% of the patients. Depression was an independent predictor for anorectal symptoms. CONCLUSIONS: This study shows the high prevalence of functional bowel symptoms in patients complaining of morbid obesity.

Psychosocial factors, psychiatric illness and functional gastrointestinal disorders: a historical perspective.

A new classification of functional gastrointestinal disorders (FGID) became available recently, based on consensus in expert committees ('Rome III process'). It is widely accepted that these frequent disorders, although their pathophysiology remains incompletely understood, result from a complex reciprocal interaction between biological, psychological and social factors that can be predisposing, precipitating and/or perpetuating. Comorbidity with psychiatric disorders, especially mood and anxiety disorders, is high. Modern epidemiologic, psychophysiological and functional neuroimaging studies have partially elucidated the mechanisms underlying the relation between cognitive-affective processes on the one hand and GI function and symptom reporting on the other. The aim of this article is to provide a noncomprehensive historical review of the literature on FGID up to the mid-20th century, with special emphasis on the role of psychosocial factors and psychiatric comorbidity. We can conclude from this review that a lot of the knowledge that became available recently through modern research methodology can also be found in the historical psychosomatic and neuroscience literature, though obviously less empirically grounded. This provides further support for an integrative, multidisciplinary biopsychosocial approach to FGID.

Rectal irrigation for patients with functional bowel disorders.

Functional bowel disorders encompass a number of symptoms including abdominal, pelvic and/or anal pain, bloating, nausea, disturbed bowel function, faecal urgency or incontinence, straining to evacuate bowels, incomplete emptying and constipation. This article examines the causes and effects of functional bowel problems on patients' quality of life. It provides an overview of the treatment options and clinical management of these conditions, focusing on biofeedback and rectal irrigation. The author reports results from a small scale audit at her hospital and concludes that rectal irrigation is a valuable treatment option for patients with functional bowel disorders.

Cognitive factors affect treatment response to medical and psychological treatments in functional bowel disorders.

OBJECTIVES: For clinical trials in functional bowel disorders (FBD), the definition of a responder, one who meets the predefined criteria for a clinical response, is needed. Factors that determine clinical response aside from treatment itself are unknown. The aim of this study was to determine what baseline and post-treatment factors affect treatment response. METHODS: Females (n=397) with FBD entering a 12-week, four-arm, randomized NIH treatment trial (desipramine (DES), CBT, pill placebo, and education) were studied at baseline and after treatment. Demographic, clinical, psychosocial, and physiological variables were considered in the analysis. A responder was defined as a patient obtaining a score>3.5 on an averaged eight-item, five-point satisfaction-with-treatment questionnaire. Baseline and post-treatment logistic regressions were performed for each treatment condition to predict the responder outcome variable. RESULTS: Similar cognitive features predisposed participants to treatment response across the treatment conditions: sense of control over the condition, positive relationship with therapist or study coordinator, confidence in treatment, improvement in maladaptive cognitions, and quality of life during treatment. Demographic and clinical variables studied were not predictive. Some treatment-specific effects predicting responder status were noted, including a reduction in stool frequency with DES treatment and lack of abuse history in the placebo group. CONCLUSIONS: For medication, psychological, and placebo treatment in FBD, satisfaction with treatment depends on cognitive factors of confidence in treatments, perceived control over illness and symptoms, and reduction in negative cognitions related to symptom experience. Addressing these issues among patients with FBD may enhance treatment response to a variety of treatments.

Recent insights on central processing and psychological processes in functional gastrointestinal disorders.

There is increasing evidence for a key role of psychological processes and their central nervous system substrates in functional gastrointestinal disorders, although the exact nature of the relationship remains only partially understood. However, progress in this key area of psychosomatic medicine is rapidly being made. In this review article, we will give an overview of recent advances in understanding the complex mechanisms by which psychological processes and functional gastrointestinal disorder symptoms reciprocally influence each other. Various lines of evidence from different branches of biomedical and psychological science will be discussed, particularly epidemiology, patho- and psychophysiology and functional brain imaging, focusing on the most recent and novel findings. We will conclude this paper with a paragraph on new insights into treatment.

Functional nonretentive fecal incontinence in children: a frustrating and long-lasting clinical entity.

Fecal incontinence is defined as the passage of stools in an inappropriate place at least once per month, for a minimum period of 2 months. This frustrating symptom is a source of considerable distress and embarrassment for the child and the family. According to the Rome III criteria fecal incontinence can be subdivided into constipation-associated fecal incontinence and functional nonretentive fecal incontinence. This short review mainly addresses functional nonretentive fecal incontinence in children. Definition, prevalence, pathophysiology, and recent updates on treatment and long-term follow-up of fecal incontinence are discussed.

Determinants of symptoms in functional dyspepsia: gastric sensorimotor function, psychosocial factors or somatisation?

BACKGROUND: Gastric sensorimotor dysfunction, psychosocial factors and somatisation are all implicated in symptom generation in functional dyspepsia (FD). AIM: To determine the relative contribution of each of these factors to overall dyspeptic symptom severity and weight loss in FD. METHODS: In 201 consecutive tertiary care patients with FD (mean age 40.1 (SD 12.6) years), gastric sensorimotor function was studied using barostat (sensitivity, compliance and accommodation). Psychosocial factors (depression and anxiety disorders, positive and negative affect, perceived stress, alexithymia and history of abuse), somatisation and co-morbid irritable bowel syndrome (IBS) and chronic fatigue symptoms were assessed using self-report questionnaires. Variables were correlated with dyspepsia symptom severity (DSS) and weight loss. Hierarchical multiple linear regression was used to identify determinants of DSS and weight loss. RESULTS: Multiple linear regression identified the following determinants of DSS: gastric sensitivity (beta = 0.77, p = 0.25), depression (beta = 0.12, p = 0.06) and somatisation (beta = 0.48, p<0.0001) (controlling for age and occupation, R(2) = 0.29, p<0.0001). The effect of depression on DSS is partially mediated by somatisation. Gastric sensitivity (beta = 2.87, p = 0.08), history of childhood sexual abuse (beta = 9.37, p = 0.0006), depression (beta = 0.19, p = 0.24) and somatisation (beta = 0.67, p = 0.01) are independent determinants of weight loss (controlling for gender and occupation, R(2) = 0.42, p<0.0001). The effect of depression on weight loss is fully mediated by somatisation. CONCLUSION: Symptom severity and weight loss in FD are determined by psychosocial factors (depression, abuse history) and somatisation, and only to a lesser extent by gastric sensorimotor function. The importance of psychosocial factors and somatisation compared to gastric sensorimotor function is most pronounced in hypersensitive patients.

Prevalence and risk factors for abdominal bloating and visible distention: a population-based study.

BACKGROUND: Abdominal bloating and visible distention are common yet poorly understood symptoms. Epidemiological data distinguishing visible distention from bloating are not available. We aimed to evaluate the prevalence and potential risk factors for abdominal bloating and visible distention separately in a representative US population, and their association with other functional gastrointestinal disorders (FGIDs). METHODS: The validated Talley Bowel Disease Questionnaire was mailed to a cohort selected at random from the population of Olmsted County, Minnesota. The complete medical records of responders were abstracted; 2259 subjects (53% females; mean age 62 years) provided bloating and distention data. RESULTS: The age and sex-adjusted (US White 2000) overall prevalence per 100 for bloating was 19.0 [95% confidence interval (CI), 16.9 to 21.2] vs 8.9 (95% CI, 7.2 to 10.6) for visible distention. Significantly increased odds for bloating alone and separately for distention (vs neither) were detected in females, and in those with higher overall Somatic Symptom Checklist (SSC) scores and higher scores of each individual SSC item. Further, females [odds ratio (OR), 1.5; 95% CI, 1.0 to 2.1], higher SSC score (OR, 1.4; 95% CI, 1.1 to 1.8), constipation-predominant irritable bowel syndrome (OR, 2.3; 95% CI, 1.3 to 4.1), dyspepsia (OR, 1.9; 95% CI, 1.1 to 3.2), and gastro-intestinal symptom complex overlap (OR, 1.7; 95% CI, 1.1 to 2.7) significantly increased odds for distention over bloating alone. CONCLUSIONS: Bloating and distention are common and have similar risk factors; somatisation probably plays a role.

Rectal irrigation in the management of functional bowel disorders: a review.

Faecal incontinence and constipation are examples of functional bowel disorders that can lead to distressing psychological and physical symptoms which seriously impact upon quality of life. Rectal irrigation has been introduced as a treatment option for such patients. This article critically reviews and evaluates the current evidence on the effectiveness of rectal irrigation as a management option for functional bowel disorders. The review was conducted using BIOSIS, AHMED, CINAHL, MEDLINE, and Web of Knowledge. From 1051 articles identified through the literacy search, only nine were specifically concerned with the evaluation of rectal irrigation as a treatment option for functional bowel disorders. The results of the literature review do indicate that rectal irrigation could be a successful treatment option for some people, however, variations between studies and methodological limitations mean evidence of the effectiveness of rectal irrigation is lacking.

Characterization of health related quality of life (HRQOL) for patients with functional bowel disorder (FBD) and its response to treatment.

BACKGROUND AND AIMS: Assessing health related quality of life (HRQOL) is becoming more important in research and clinical care. However, little information is available on the performance of HRQOL questionnaires for the functional bowel disorders (FBD). The aims of this study were to (a) understand the performance of the Sickness Impact Profile (SIP) and IBS-QOL for the functional bowel disorders at baseline and after treatment, (b) determine which HRQOL subscales best improve with treatment, (c) determine clinically meaningful improvement, and (d) determine the predictors of HRQOL at baseline and in response to treatment. METHODS: Women with moderate to severe FBD were evaluated using both medical (desipramine vs placebo) and psychological (cognitive-behavioral therapy vs education) treatments. Clinical and psychosocial questionnaires along with the SIP and IBS-QOL were given at baseline and after 12-wk treatment. RESULTS: (a) Patients with FBD experience functional limitations in social interactions, home management, and recreational activities, respond emotionally to the pain, feel helpless, out of control, depressed, and irritable, and perceive restrictions in lifestyle relating to toilet accessibility, and eating; (b) HRQOL is not different among the FBD diagnoses or IBS subgroups; (c) the IBS-QOL is more responsive to treatment than the SIP; (d) meaningful clinical improvement is 2.8 points for SIP and 14 for IBS-QOL; and (e) improvement is demonstrated primarily in psychosocial rather than physical domains. In addition, we found that expectation of benefit is greater for taking a pill over a psychological intervention, and the predictive effects of abuse history and pain on outcome is mediated by psychosocial factors. CONCLUSIONS: The data support the value of the IBS-QOL over the SIP, and provide new information on the profile of impairment in FBD, and the ways in which medical and psychological treatments produce improvement in HRQOL.

Irritable bowel syndrome and the Rome III criteria: for better or for worse?

The paper by Sperber et al. in this issue is an early evaluation of the Rome III criteria against the Rome II criteria for irritable bowel syndrome that throws up several important observations. A three to four-fold increase was observed in irritable bowel syndrome prevalence with the Rome III criteria. Individuals with the Rome II criteria had more doctor visits, perception of stress and a negative global feeling. There could be a shift of individuals between irritable bowel syndrome and other functional bowel disorder diagnostic groups such as functional constipation and functional bloating. In this review, it is suggested that rigid application of the symptom frequency and duration requirements of the older Rome criteria could have introduced a selection bias for patients with greater psychological disturbance, and that this could have impacted negatively on our perception and management of irritable bowel syndrome. The findings of Sperber et al. suggest that the new Rome III criteria may enable us to pay more attention to the average irritable bowel syndrome patient we see in our clinics as opposed to the chronically severe patient. It is proposed that improved management of our average patient may translate into better outcomes in terms of reduction in specialist referral, unnecessary surgery and potentially harmful alternative treatments.

Functional bowel disorders in rotating shift nurses may be related to sleep disturbances.

OBJECTIVES: To compare the frequency and severity of bowel disturbances between rotating shift and regular day nurses and to determine whether functional bowel disorders (FBD) were related to sleep disturbances. METHODS: Sixty regular day and 58 rotating shift nurses answered three standardized questionnaires: the Gastrointestinal Symptom Questionnaire; the Hospital Anxiety and Depression Scale; and the Irritable Bowel Syndrome Symptoms Evaluation Questionnaire, which included the Sleep Questionnaire, on the frequency and severity of gastrointestinal symptoms, sleep disturbances and psychological distress. Responses to these questions were numerically rated and the sums of individual symptom scores under the respective categories were computed and analysed using statistical tests, as appropriate. RESULTS: Although 22 out of 58 rotating shift nurses (38%) had FBD, only 12 out of 60 regular day nurses (20%) had it (P=0.04). The mean FBD symptom score (P<0.002), sleep disturbance score (P<0.0001) and anxiety score (P<0.002) were all significantly higher among the rotating shift nurses. FBD symptom scores were positively correlated with the sleep disturbance (P=0.0001), anxiety (P=0.0001), depression (P=0.0001), well-being (P=0.0001), fatigue (P=0.0001), and somatic pain scores (P=0.0001). Sleep disturbance (P=0.04), decreased well-being (P=0.04), anxiety (P=0.02), and somatic pain (P=0.03) were independent predictors of FBD symptoms. CONCLUSION: FBD were more common and severe among rotating shift nurses. The FBD symptom score was positively and independently correlated with the sleep disturbance score, suggesting that poor sleep might be associated with increased FBD symptoms in rotating shift nurses.
