- Background Clinical data suggest gender differences in gastrointestinal pain, but very little experimental data exist. Esophageal painful thresholds to mechanical, thermal, electric, and chemical stimuli can be measured with the esophageal multimodal pain model. The aim was to measure the effect of gender and mild esophagitis on esophageal pain perception. Methods Thirty-five healthy asymptomatic volunteers [19 men, median age 29 (22-56 years)] underwent upper GI endoscopy, 24 h pH/impedance measurement, and multimodal esophageal pain stimulation before and after sensitization with acid. Stimulus intensities at painful thresholds were recorded. Key Results Men had higher pain thresholds (PT) to mechanical stimulation (mean volume: men 20.9 +/- 10 mL vs women 15.2 +/- 6.8 mL, P = 0.02) and more men tolerated the maximum acid challenge (58% vs 20%, P = 0.03). There were no differences between genders for PT to 1 thermal stimulation [mean stimulation time (men, women): heat; 20 +/- 5 s vs 21 +/- 6 s or cold; 33.3 +/- 20.1 s vs 20.7 +/- 21.4 s, P > 0.2], 2 electrical current (mean current: men 17.6 +/- 9.2 mA vs women 12.9 +/- 3.7 mA, P = 0.11), or 3 acid volume [median volume: men 200 (20; 200) mL vs women 133 (40; 200) mL, P = 0.2]. Fifteen asymptomatic subjects had mild esophagitis (10 men, all Los Angeles A). There were no differences in esophageal PT between subjects with normal endoscopy or mild esophagitis (all P > 0.3). Conclusions & Inferences The effects of gender and mild esophagitis on esophageal multimodal pain perception have been measured in asymptomatic volunteers. The study suggests that gender, not mild esophagitis, tends to influence mechanical and chemical esophageal pain.

- Goals:To evaluate validity, reliability, and responsiveness of the Short Health Scale (SHS) in irritable bowel syndrome (IBS) patients.Background:Subjective health assessment is central when treating patients with IBS. The Short Health Scale is a quick 4-item questionnaire covering most aspects of subjective health that has been validated for inflammatory bowel disease.Study:To test validity, 451 patients with IBS (mean age, 38 y; 81% females) completed the SHS and questionnaires assessing IBS symptom severity (IBS-SSS), gastrointestinal (GI)-specific anxiety (VSI), and quality of life (IBSQOL). To evaluate reliability and responsiveness to changes, the questionnaires were repeated after 2 weeks in 18 patients, and after 12 weeks in 212 patients who had completed a patient-education program.Results:Validity was documented with (1) gradually increasing mean scores for all 4 SHS items with increasing IBS-SSS (Pless than0.0001), and (2) correlations between the 4 SHS items and the corresponding items from the other subjective health assessment tools [item 1 (symptom burden): =0.67, item 2 (daily function): =-0.44 to -0.46, item 3 (disease-related worry): =-0.51 to 0.57, item 4 (general well-being): =-0.34 to -0.46, Pless than0.0001]. Reliability was confirmed (Spearman greater than0.7 and intraclass correlations greater than0.7). Responsiveness was good with responders to the patient-education program (IBS-SSS reduction 50 points) having significant reductions in 3 of the SHS items (Pless than0.05), and borderline change for the fourth SHS item (P=0.06).Conclusions:SHS is a health measure that shows promising evidence of validity, reliability, and responsiveness in IBS patients. It is quickly completed and evaluated, which supports its usefulness in the busy clinical practice.

- The effects of oxytocin in the gastrointestinal tract are unclear. The aim of this study was to examine the effect of infusion of oxytocin on colonic motility and sensitivity in healthy women. Fourteen healthy women were investigated twice. A 6-channel perfusion catheter, with three recording points (2 cm apart) proximally and three recording points distally to a barostat balloon, was inserted to the splenic flexure. An intestinal feeding tube was placed in the mid-duodenum. A 90-min duodenal lipid infusion of 3 kcal min(-1) was administered. Thirty minutes after the start of the lipid infusion, the subject randomly received either 20 or 40 mU min(-1) of oxytocin, or isotonic saline as intravenous infusions for 90 min. Meanwhile, the colonic motility was recorded. During the last 30 min of oxytocin and saline infusion, the visceral sensitivity to balloon distensions was examined. During lipid infusion the number of antegrade contractions per hour was 0.7 +/- 0.3 after saline and 3.9 +/- 1.4 after oxytocin (P = 0.03), indicating more pronounced lumen-occlusive contractile activity after oxytocin administration. Some of these consisted of high-amplitude (> 103 mmHg in amplitude) antegrade contractions. Lipid infusion evoked a decrease of the balloon volume, reflecting increased colonic tone, but there was no difference between saline and oxytocin. Sensory thresholds did not differ significantly between saline and oxytocin. Infusion of oxytocin stimulates antegrade peristaltic contractions in stimulated colon in healthy women. The effects of oxytocin on colonic motor activity deserve to be further explored, especially in patients with colonic peristaltic dysfunction.

- OBJECTIVES: Improvement of gastric accommodation has been proposed as a potential explanation for the positive effect of gastric electrical stimulation (GES) on nausea/vomiting. A drinking test has been suggested as a noninvasive measure of gastric accommodation capacity. METHODS: Eight patients with therapy refractory nausea and vomiting and nonapproved diagnosis for GES (chronic intestinal pseudo-obstruction (CIP, n=1), functional dyspepsia (FD, n=3), postsurgical gastroparesis (PSGP, n=4) underwent temporary percutaneous GES for 10-14 days, randomized to stimulation ON or OFF, respectively. 19 patients [CIP (n=1), diabetic gastroparesis (n=5), FD (n=5), idiopathic gastroparesis (n=4), PSGP (n=4)] received permanent GES (Enterra, Medtronic) (follow-up at baseline, 6 and 12 months). At the end of each stimulation period a slow caloric satiety drinking test was performed (Nutridrink 1.5 kcal/ml, 15 ml/min). RESULTS: Healthy volunteers had higher drinking capacity compared to patients at baseline (1630+/-496 kcal vs. 887+/-412; P<0.001) and less composite symptom score (128+/-51 vs. 235+/-83; P<0.001). With temporary percutaneous GES, there was no significant change in drinking capacity during stimulation ON versus OFF (746+/-383 vs. 734+/-427 kcal) and symptom severity at the drinking test was unchanged. For patients having permanent GES there was no significant difference at 6 months (876+/-277 kcal) versus baseline, and no difference between symptomatic responders and nonresponders in change in drinking capacity (P=0.7). CONCLUSION: GES had no effect on proximal gastric function as evaluated by the slow caloric satiety drinking test. This seems to be the case for patients with approved as well as nonapproved indications for GES, and irrespective of the symptomatic response.

- Irritable bowel syndrome is a common and often chronic functional bowel disorder that can cause severe disruption of daily functioning in those affected, with subsequent high healthcare utilization and work absenteeism. Nurses represent an underutilized group in the current management of irritable bowel syndrome. The aim of this study was to systematically develop a person-centered support intervention in irritable bowel syndrome and evaluate this in a pilot study. The development followed the revised framework for complex interventions from the Medical Research Council and involved literature reviews and multiprofessional expert groups. The intervention was then tested in a pilot study including 17 patients and evaluated through validated questionnaires measuring irritable bowel syndrome symptom severity, gastrointestinal-specific anxiety, and self-efficacy as well as through interviews. There was a significant improvement in irritable bowel syndrome symptom severity between baseline and follow-up, but not for self-efficacy or gastrointestinal-specific anxiety. The patients' perceptions of participating in the intervention were positive and induced a learning process; they were able to form a supportive relationship with the nurse and their ability to self-manage improved. The promising results from this small pilot study in terms of feasibility, potential efficacy, and the patients' positive feedback make this intervention a suitable candidate for a larger controlled trial.

- Background: Differences regarding symptoms, coping abilities, and quality of life (QOL) between men and women with irritable bowel syndrome (IBS) have been reported but data are sparse and sometimes conflicting. The aim of present study was to investigate gender differences in gastrointestinal, extra-intestinal, and psychological symptoms, and sense of coherence (SOC) and QOL in a large group of patients diagnosed with IBS. Methods: We analyzed questionnaire data from 557 patients (152 men) diagnosed with IBS consecutively included in studies at an outpatient clinic for functional bowel disorders between 2002 and 2010. Following questionnaires were included: IBS severity scoring system (IBS-SSS), Hospital Anxiety and Depression Scale (HAD), IBSQOL Scale, Visceral Sensitivity Index (VSI), SOC Scale, Bristol Stool Form Scale (BSFS), and Patient Health Questionnaire (PHQ-15). Key Results: Women had harder stools (FDR-adjusted p-value: q = 0.033), more severe bloating (q = 0.020), higher symptom severity (q = 0.042), higher total somatic symptom burden (q = 0.035), lower SOC (q = 0.042), and lower QOL. Women rated more general anxiety (q = 0.017) and gastrointestinal-specific anxiety (q = 0.042), but there were no group differences in depression, pain, stool frequency, impact on daily life, dissatisfaction with bowel habit, or extra-colonic symptoms. The differences found were small (effect sizes: r < 0.3). Conclusions & Inferences: In this study, we demonstrated more similarities than differences between men and women with IBS. The largest difference were seen for QOL which might reflect certain structural stressors to which women in general are more exposed than men. © 2015 John Wiley & Sons Ltd.

- BACKGROUND & AIMS: There are few data from longitudinal studies of the gastrointestinal and psychologic features of irritable bowel syndrome (IBS). We studied within-person correlations among features of IBS, along with progression of gastrointestinal (GI) symptoms and quality of life, and factors associated with changes over time. METHODS: We performed a longitudinal study of 276 patients with IBS in Sweden (70% female; ages, 19-76 years) who completed questionnaires, each year for 5 years, about their GI symptom severity, quality of life, GI-specific anxiety, general anxiety, depression, and coping resources. We performed within-person correlation analyses, latent class growth analysis, and random-intercept cross-lagged panel analysis. RESULTS: Within-person correlations with GI symptom severity were strongest for quality of life (r = -0.56) and GI-specific anxiety (r = 0.47). Progression of GI symptom severity was defined based on 3 classes; the class with the highest mean levels of GI, depression, and (GI-specific) anxiety symptoms at baseline did not improve over the 5-year period, contrary to the other classes. GI-specific anxiety was associated with an increase in GI symptom severity and decrease in quality of life 1 year later (P < .05) but other features of IBS were not. CONCLUSIONS: In a 5-year study of patients with IBS in Sweden, we found 3 classes of GI symptom development. We found levels of GI-specific anxiety to associate with GI symptom severity and quality of life 1 year later. Clinicians should be aware of GI-specific anxiety in patients with IBS, to identify patients at risk for lack of long-term symptom improvement with standard medical treatment.
