Abstract
Background Functional dyspepsia (FD) refers to the presence of one or more gastrointestinal symptoms including postprandial fullness, epigastric pain, burning, and early satiety without an organic explanation for chronic symptoms. FD causes considerable discomfort in patients and affects their everyday activity and productivity. Because most conventional treatments have limited efficacy, numerous patients seek alternatives such as herbal medicines. In this proposed study, we will conduct a clinical trial of an herbal drug, Banha-sasim-tang (BST). Furthermore, participants will be limited to those classified as having an excess pattern by using an instrument of pattern identification for FD to determine the efficacy of BST in a specific subset of patients. Methods This randomized, blinded, parallel-group clinical trial of BST versus placebo will consist of 4 weeks of oral administration of BST or placebo and a 4-week follow-up period. The Korean version of the symptom-based questionnaire of the Nepean Dyspepsia Index (NDI-K) will be used as the primary outcome measure. Secondary outcome measures will include the quality-of-life (QoL) evaluation from the NDI-K, the FD-related QoL (FD-QoL) scale, assessment of gastric myoelectrical dysrhythmias (GMA), and a Visual Analog Scale (VAS) analysis. Discussion The results of this trial are expected to provide relevant evidence demonstrating that BST can be used as an effective treatment in a specific subset of FD subjects.

Abstract
Functional dyspepsia is one of the most prevalent functional gastrointestinal disorders. Functional dyspepsia comprises three subtypes with presumed different pathophysiology and aetiology: postprandial distress syndrome (PDS), epigastric pain syndrome (EPS) and a subtype with overlapping PDS and EPS features. Functional dyspepsia symptoms can be caused by disturbed gastric motility (for example, inadequate fundic accommodation or delayed gastric emptying), gastric sensation (for example, sensations associated with hypersensitivity to gas and bloating) or gastric and duodenal inflammation. A genetic predisposition is probable but less evident than in other functional gastrointestinal disorders, such as irritable bowel syndrome (IBS). Psychiatric comorbidity and psychopathological state and trait characteristics could also play a part, although they are not specific to functional dyspepsia and are less pronounced than in IBS. Possible differential diagnoses include Helicobacter pylori infection and peptic ulceration. Pharmacological therapy is mostly based on the subtype of functional dyspepsia, such as prokinetic and fundus-relaxing drugs for PDS and acid-suppressive drugs for EPS, whereas centrally active neuromodulators and herbal drugs play a minor part. Psychotherapy is effective only in a small subset of patients, whereas quality of life can be severely affected in nearly all patients. Future therapies might include novel compounds that attempt to treat the underlying gastric and duodenal inflammation.

Abstract
BACKGROUND Functional dyspepsia (FD) is a very common condition affecting more than 10% of the population. While there is no cure, a few drugs have been found to be effective for the relief of symptoms, although most are only effective in a subgroup of patients. We assess and compare the efficacy of a fixed peppermint/caraway-oil-combination (Menthacarin) on symptoms and quality of life (QoL) in patients with FD symptoms consistent with epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS). METHODS In a prospective, double-blind, multicenter trial, 114 outpatients with chronic or recurrent FD were randomized and treated for 4 weeks with the proprietary peppermint- and caraway-oil-preparation Menthacarin or placebo (2×1 capsule/day). Improvement of abdominal pain and discomfort were used as co-primary efficacy measures (scores measured with the validated Nepean Dyspepsia Index). KEY RESULTS After 2 and 4 weeks, active treatment was superior to placebo in alleviating symptoms consistent with PDS and EPS (P all <.001). After 4 weeks of treatment, pain and discomfort scores improved by 7.6±4.8 and 3.6±2.5 points (full analysis set; mean±SD) for Menthacarin and by 3.4±4.3 and 1.3±2.1 points for placebo, respectively. All secondary efficacy measures showed advantages for Menthacarin. CONCLUSIONS & INFERENCES Menthacarin is an effective therapy for the relief of pain and discomfort and improvement of disease-specific QoL in patients with FD and significantly improves symptoms consistent with EPS and PDS.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common functional gastrointestinal disorder. Accumulating evidence suggests the crucial role of central nervous system in the development and maintenance of FD. In particular, periaqueductal gray (PAG) has demonstrated an important role in modulation of pain and emotion, which may be related to FD. However, the study of the PAG in FD is still limited. This study aimed to assess intrinsic connectivity of the PAG in FD patients. METHODS Resting-state functional magnetic imaging (fMRI) data were collected from 66 FD patients and 42 healthy controls (HCs). Functional connectivity analysis was performed to investigate the PAG connectivity pattern differences between the patients and HCs. We then examined the relationships between functional connectivity within the PAG networks and FD symptoms. KEY RESULTS Compared to HCs, patients had increased PAG connectivity with the insula, and decreased PAG connectivity with the orbitofrontal cortex (OFC), dorsolateral prefrontal cortex (dlPFC) and hippocampus/parahippocampus (HIPP/paraHIPP). There were positive correlations between disease duration and PAG connectivity with the putamen and supplementary motor area (SMA), and positive correlations between symptom severity and PAG connectivity with the insula. FD patients with high level of anxiety and depression had altered PAG connectivity with the anterior cingulate cortex (ACC), precuneus, dlPFC and caudate, compared to other patients. CONCLUSIONS & INFERENCES These findings indicate that abnormal intrinsic network of the PAG might be associated with abnormality of pain processing and disruption of emotion processing in FD patients. Our study further complements neuroimaging findings about FD.

The Validity of a New Structured Assessment of Gastrointestinal Symptoms Scale (SAGIS) for Evaluating Symptoms in the Clinical Setting. Dig Dis Sci 2017; 62:1913-1922. [PMID: 28551709 DOI: 10.1007/s10620-017-4599-6] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2016] [Accepted: 04/29/2017] [Indexed: 12/17/2022]
Abstract
BACKGROUND The clinical assessments of patients with gastrointestinal symptoms can be time-consuming, and the symptoms captured during the consultation may be influenced by a variety of patient and non-patient factors. To facilitate standardized symptom assessment in the routine clinical setting, we developed the Structured Assessment of Gastrointestinal Symptom (SAGIS) instrument to precisely characterize symptoms in a routine clinical setting. AIMS We aimed to validate SAGIS including its reliability, construct and discriminant validity, and utility in the clinical setting. METHODS Development of the SAGIS consisted of initial interviews with patients referred for the diagnostic work-up of digestive symptoms and relevant complaints identified. The final instrument consisted of 22 items as well as questions on extra intestinal symptoms and was given to 1120 consecutive patients attending a gastroenterology clinic randomly split into derivation (n = 596) and validation datasets (n = 551). Discriminant validity along with test-retest reliability was assessed. The time taken to perform a clinical assessment with and without the SAGIS was recorded along with doctor satisfaction with this tool. RESULTS Exploratory factor analysis conducted on the derivation sample suggested five symptom constructs labeled as abdominal pain/discomfort (seven items), gastroesophageal reflux disease/regurgitation symptoms (four items), nausea/vomiting (three items), diarrhea/incontinence (five items), and difficult defecation and constipation (2 items). Confirmatory factor analysis conducted on the validation sample supported the initially developed five-factor measurement model ([Formula: see text], p < 0.0001, χ 2/df = 4.6, CFI = 0.90, TLI = 0.88, RMSEA = 0.08). All symptom groups demonstrated differentiation between disease groups. The SAGIS was shown to be reliable over time and resulted in a 38% reduction of the time required for clinical assessment. CONCLUSIONS The SAGIS instrument has excellent psychometric properties and supports the clinical assessment of and symptom-based categorization of patients with a wide spectrum of gastrointestinal symptoms.

Abstract
BACKGROUND In the treatment of functional dyspepsia, the placebo effect has been reported to be high, and the influence of the patient-practitioner relationship may be a major component of this effect. The specific and non-specific effects of acupuncture cannot be easily distinguished, and the patient-practitioner relationship may influence the total therapeutic effect in clinical practice. There have been no studies that investigate the influence of patient-practitioner relationship on acupuncture treatment for patients with functional dyspepsia. METHODS Patients with postprandial distress syndrome, a functional dyspepsia subtype, will be recruited at three hospitals (two in Korea and one in USA) for an international, multi-center, randomized, patient/assessor-blinded, clinical trial. The total anticipated sample size is 88. The participants will be randomly allocated into two groups: an augmented interaction group and a limited interaction group. Acupuncture, with total 12 acupoints, will be performed twice weekly for 4 weeks in both groups. Trained practitioners will provide an "augmented" or "limited" interaction context, as determined by random allocation. The primary outcome measure is the proportion of responders, the proportion of participants who answer "yes" to more than half of the adequate relief questions during the study. Secondary outcome measures include questionnaires for quality of life and symptoms of dyspepsia, and maximum tolerable volume of nutrient drink test. Data will be collected at baseline and following 4 weeks of acupuncture. DISCUSSION This study will evaluate the influence of the patient-practitioner interaction on clinical effects of acupuncture in patients with functional dyspepsia.

Abstract
BACKGROUND The Rome III criteria subdivide functional dyspepsia (FD) in the epigastric pain syndrome (EPS) and the postprandial distress syndrome (PDS) based on the frequency of the symptoms to optimize the diagnostic and therapeutic approach. However, it is unclear to which extent the frequency of the symptoms is related to their severity. Our aim was to explore the frequency and severity of dyspeptic symptoms and their relationship in FD patients. METHODS Functional dyspepsia patients fulfilling the Rome III diagnostic completed a questionnaire that evaluated the frequency and severity of FD symptoms. The concordance between the severity and frequency categories was analyzed by means of spearman correlation and the concordance correlation coefficient (ρc ). KEY RESULTS In the entire patient cohort (n=421), the classification of symptoms severity and frequency showed good concordance for all symptoms. In the EPS subgroup (n=….), the symptom severity and frequency score of epigastric pain showed a poor correlation (r=.28; ρc =0.07). The PDS subgroup (n=…) showed a good correlation for most of the symptoms. Due to its limited occurrence in this group, the correlation of the severity and frequency scores for epigastric pain is of little relevance (r=.79; ρc =0.58). The overlap EPS-PDS group showed good correlation for most of the symptoms, except for epigastric pain (pain r=.24; ρc =0.09). CONCLUSIONS & INFERENCES We conclude that the information given by the assessment of frequency and severity of PDS symptoms is comparable and hence one of the scores sufficiently identifies symptom pattern in PDS patients. In EPS patients, both the symptom frequency and severity should be taken into account as two separate entities.

Abstract
Introduction. Functional dyspepsia (FD), a common upper gastrointestinal disease, is difficult to manage because of the limitations of current conventional treatments. Yukgunja-tang (YGJT) is widely used to treat FD in clinical practice in Korea, Japan, and China. However, YGJT significantly improves few symptoms of FD. In Korean medicine, FD is a well-known functional gastric disease that shows difference in the effect of herbal medicine depending on constitution or type of Korean medicine diagnosis. This study aims to investigate the efficacy of YGJT on FD patients classified by 3-dimensional facial measurement using a 3-dimensional facial shape diagnostic system (3-FSDS). Methods. A placebo-controlled, double-blind, randomized, two-center trial will be performed to evaluate the efficacy of YGJT on FD patients. Eligible subjects will be initially classified as two types by 3-dimensional facial measurement using the 3-FSDS. Ninety-six subjects (48 subjects per each type) will be enrolled. These subjects will be randomly allocated into treatment or control groups in a 2 : 1 ratio. YGJT or placebo will be administered to each group during the 8-week treatment period. The primary outcome is total dyspepsia symptom scale, and the secondary outcomes include single dyspepsia symptom scale, proportion of responders with adequate symptom relief, visual analog scale, Nepean dyspepsia index-Korean version, functional dyspepsia-related quality of life, and spleen qi deficiency questionnaire. Discussion. This is the first randomized controlled trial to assess the efficacy of the YGJT on FD patients classified by 3-dimensional facial measurement. We will compare the treatment effect of the YGJT on FD patients classified as two types using the 3-FSDS. The results of this trial will help the FD patients improve the symptoms and quality of life effectively and provide objective evidence for prescribing the YGJT to FD patients in clinical practice. Trial Registration. This trial is registered with Clinical Research Information Service Identifier: KCT0001920, 15 May, 2016.

Abstract
BACKGROUND Delayed gastric emptying and bile reflux are common concerns in long-term survivors after Whipple surgery. The study was designed to assess modified retro colic retro gastric gastrojejunostomy in reducing macro and microscopic bile reflux and impact on dyspepsia related quality of life in long-term survivors. METHODS Out of 43 patients operated, 23 long-term survivors were included. All underwent gastroscopy and bile reflux was grouped as normal, yellowish bile lakes and presence of greenish bile lakes. Six standard gastric biopsies were taken. Microscopic bile reflux index (BRI) was calculated and a score more than 14 was considered significant. Validated Nepean dyspepsia index-short form (NDI-SF) was used to assess the severity of dyspepsia-related quality of life and compared with age and gender-matched control. RESULTS The median age was 48 (21-70) years. Median survival of the group was 37 months (6-40). Endoscopically, 20/23 (87%) had macroscopic bile reflux (74% yellowish bile lakes, 13% greenish bile lakes). None had stomal ulcers or macroscopic inflammation. Mean bile reflux index score was 9.7 (range 1.77-34). Mean NDI-SF score of Whipple group was 23.1 (SD 8.88). In controls, mean score was 19.9 (SD 8.23), showing no significant difference (p = 0.245). CONCLUSIONS Though there was macroscopic bile reflux, clinical symptoms and microscopic changes were minimal. The modified technique had good long-term results.

Abstract
BACKGROUND A validated patient-reported outcome instrument is lacking for the functional dyspepsia/postprandial distress syndrome. AIM To validate the Leuven Postprandial Distress Scale (LPDS). METHODS The LPDS diary, comprising eight symptoms with verbal descriptors rated for severity (0-4), was derived from focus groups and cognitive debriefing. It was used in a 2-week run-in, 8-week double-blind placebo-controlled trial of itopride 100 mg t.d.s. Results in 60 patients, with concealed treatment allocation, were used to analyse LPDS content validity, consistency, reliability and responsiveness. Patients also filled out Patient Assessment of Gastrointestinal Symptoms (PAGI-SYM), Nepean Dyspepsia Index, overall treatment evaluation and overall symptom severity questionnaires. Construct validity was evaluated by known-group analyses and by correlating LPDS with these additional questionnaires. Minimum Clinically Important Difference was determined from threshold changes in anchor questionnaires. RESULTS Symptom patterns and factor analysis identified three cardinal symptoms of postprandial distress syndrome (early satiation, postprandial fullness, upper abdominal bloating), whose mean intensities generate weekly LPDS scores. Known-groups analysis showed large-effect-size differences in LPDS scores (Cohen's d = 2.16). Strong correlations (r > 0.57) between LPDS scores and relevant anchors at baseline indicate good convergent validity. Internal consistency of LPDS was good (α > 0.85) with high inter-item correlations (0.67-0.76), and test-retest reliability (r = 0.85). Changes in LPDS scores were highly convergent with changes in overall treatment evaluation, overall symptom severity and PAGI-SYM (r > 0.52). minimum clinically important difference analysis generated thresholds of 0.4-0.6. CONCLUSIONS The Leuven Postprandial Distress Scale, which is supported by the European Medicines Agency, is a sensitive and reliable patient-reported outcome instrument to assess symptoms in the functional dyspepsia/postprandial distress syndrome.

Abstract
OBJECTIVES This study was implemented to evaluate the effect of individualized acupuncture treatment (AT) on functional dyspepsia (FD). METHODS A randomized, waitlist-controlled, two-center trial was performed. Seventy-six patients with FD were enrolled in the trial with partially individualized AT in a more realistic clinical setting performed twice a week for 15 minutes a session over 4 weeks. The participants were randomly allocated to a group receiving 8 sessions of AT for 4 weeks or a waitlist control group. After 4 consecutive weeks, the AT group was followed up without AT and the control group received the identical AT. The proportion of responders with adequate symptom relief, Nepean Dyspepsia Index (NDI), FD-related quality of life, Beck Depression Inventory, State-Trait Anxiety Inventory, Acupuncture Belief Scale, and acupuncture credibility test were assessed. RESULTS After the first 4 weeks, the proportion of responders significantly improved (59% in AT group [n = 37] versus 3% in control group [n = 39]; p < 0.001). The difference was no longer significant at 8 weeks, at which point the waitlist control group showed similar improvement after receiving AT (68% in the AT group versus 79% in the control group). Total NDI scores were significantly reduced in the AT group compared with the waitlist group (p = 0.03). Among NDI items, discomfort (p = 0.01), burning (p = 0.02), fullness after eating (p = 0.02), and burping (p = 0.02) were significantly improved in the AT group compared with the control group. No significant differences were observed between groups in other secondary variables. CONCLUSION Individualized AT adequately relieves symptoms in patients with FD, and this effect may persist up to 8 weeks.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a complex condition with multiple factors contributing to its aetiology and pathophysiology. Aetiologically these include genetics, life-time events and environment, and physiologically, changes in motility, central processing, visceral sensitivity, immunity, epithelial permeability and gastrointestinal microflora. Such complexity means there is currently no specific reliable biomarker for IBS, and thus IBS continues to be diagnosed and classified according to symptom based criteria, the Rome Criteria. Carefully phenotyping and characterisation of a 'large' pool of IBS patients across Europe and even the world however, might help identify sub-populations with accuracy and consistency. This will not only aid future research but improve tailoring of treatment and health care of IBS patients. PURPOSE The aim of this position paper is to discuss the requirements necessary to standardize the process of selecting and phenotyping IBS patients and how to organise the collection and storage of patient information/samples in such a large multi-centre pan European/global study. We include information on general demographics, gastrointestinal symptom assessment, psychological factors, quality of life, physiological evaluation, genetic/epigenetic and microbiota analysis, biopsy/blood sampling, together with discussion on the organisational, ethical and language issues associated with implementing such a study. The proposed approach and documents selected to be used in such a study was the result of a thoughtful and thorough four-year dialogue amongst experts associated with the European COST action BM1106 GENIEUR (www.GENIEUR.eu).

Abstract
OBJECTIVES We aimed to develop and validate Kinyarwanda versions of Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) and Short-Form Nepean Dyspepsia Index (SF-NDI) to measure the frequency and severity of dyspepsia and associated quality-of-life impact in Rwanda. SETTING A single, tertiary care centre in Rwanda. PARTICIPANTS 200 consecutive Kinyarwanda-speaking patients referred to endoscopy (100 patients) or medical outpatients (100 patients). INTERVENTIONS Kinyarwanda versions of the SF-LDQ and SF-NDI were developed from English versions by translation, with back translation, crosschecking and pilot testing. Study participants completed these questionnaires at enrolment (time 1), and then completed the surveys again with blinded phone interviewers 3 days later (time 2). 20 randomly selected participants, diagnosed with a peptic ulcer on index endoscopy, completed a third survey by phone at day 30 (time 3), after therapy. PRIMARY OUTCOME MEASURES Internal consistency at time 1 (by Cronbach's α) and test-retest reliability between time 1 and time 2 (Spearman's correlation coefficient) for translated SF-LDQ and SF-NDI; validity versus clinical diagnosis (by receiver operating characteristic (ROC) curve) and responsiveness to treatment for SF-LDQ (by change in mean score). All outcomes were measured as per protocol. RESULTS Cronbach's α of the translated SF-LDQ was 0.93, showing high internal consistency. Spearman's correlation coefficient comparing time 1 and time 2 was 0.978 (p<0.001), demonstrating high reliability. Cronbach's α for the translated SF-NDI was 0.92. A cut-off score of 16 on the SF-LDQ showed a sensitivity of 97% and a specificity of 71% for the diagnosis of dyspepsia, correctly classifying 89% of patients. In the responsiveness analysis, the mean SF-LDQ score was reduced from 20.1 prior to treatment to 13.9 after 30 days of treatment (p=0.003). CONCLUSIONS The Kinyarwanda versions of the SF-LDQ and SF-NDI were valid, reliable and responsive to treatment.

Abstract
BACKGROUND There is increasing evidence in support of the presence of abnormal central changes (compared to healthy controls) in functional dyspepsia (FD) in addition to the peripheral changes in gastrointestinal tract. PURPOSE This systematic review aims to provide an integrative understanding of the abnormal functional brain activity, visceral sensation, dyspeptic symptoms, and psychological changes of FD. Electronic and hand searches were conducted to identify functional neuroimaging studies involving FD patients. Sixteen studies were selected and divided into three categories: 10 resting state studies, three visceral distention studies, and three acupuncture studies. Changes were reported in several brain areas in FD patients including the frontal cortex, somatosensory cortex, insula, anterior cingulate cortex, thalamus, hippocampus, and amygdala. These brain activity changes were associated with visceral hypersensitivity, dyspeptic symptoms, poorer quality of life, anxiety, and depression. The results show that FD is associated with functional abnormalities in sensory and pain modulation, emotion, saliency, and homeostatic processing regions. The diversity of conditions, heterogeneous results, poorly standardized diagnoses of FD, and various comorbidities may be responsible for the variability in the results.

Abstract
BACKGROUND Gastroesophageal reflux disease lowers the quality of life and increases medical costs. Electroacupuncture has been used to ease symptoms and improve gastrointestinal motility in patients with gastroesophageal reflux disease. The main purposes of this study are to evaluate the efficacy and safety of this procedure. METHODS/DESIGN This is a protocol for a randomized, patient-blinded, assessor-blinded, sham-controlled trial. Sixty participants with symptoms of gastroesophageal reflux disease, who have previously undergone standard treatment, will be recruited from August 2015 at Kyung Hee University Korean Medicine Hospital. The participants will be allocated to either the electroacupuncture (n = 30) or the sham electroacupuncture group (n = 30); the allocation will be concealed from both the participants and the assessors. The EA group will undergo penetrating acupuncture at 18 fixed points and two optional points chosen using the pattern identification for gastroesophageal reflux disease. Electrical stimulation will be applied at some of the acupoints. The sham electroacupuncture group will undergo nonpenetrating acupuncture without electrical stimulation at 18 nonspecific points, each of which will be only 2 cm away from the true acupoints used in the electroacupuncture group. In both groups, the procedure will be performed using the Park device. The treatment will last for 6 weeks (with two sessions each week), and the outcome will be evaluated at baseline, 3 weeks, and 6 weeks. The primary outcome will be the proportion of responders with adequate symptom relief, whereas the secondary outcomes will comprise the results of the Nepean dyspepsia index; the Korean gastrointestinal symptom rating scale; the EQ-5D™; levels of gastrin, motilin, and inflammatory cytokines; the perceived stress scale; the qi-stagnation questionnaire; the patient global impression of change; and the spleen qi deficiency questionnaire. DISCUSSION The results of this trial will provide information about the efficacy and safety of electroacupuncture in the treatment of gastroesophageal reflux disease symptoms, as well as evidence regarding the use of electroacupuncture to treat gastroesophageal reflux disease in real clinical practice.

Abstract
BACKGROUND Functional dyspepsia (FD) is a prevalent gastric disorder that is difficult to manage due to lack of satisfactory treatments. Acupuncture has been studied with regard to the rising need for treating FD, but the mechanism verifying its efficacy has not yet been fully revealed. The aim of this study is to explore the efficacy and mechanism of acupuncture for FD compared with a sham group. METHODS/DESIGN We describe a proposal for a randomized, assessor-blind, sham-controlled trial with 70 eligible participants who will be randomly allocated either into an acupuncture or a sham group. Participants in the acupuncture group will receive 10 sessions of real acupuncture treatment and those in the sham group will be treated with identical sessions using a Streitberger needle. Functional magnetic resonance imaging (fMRI) and metabolomics studies will be implemented before and after 4 weeks of treatment to investigate the mechanism of acupuncture. The primary outcome is a proportion of responders with adequate symptom relief and the secondary outcomes include the Nepean Dyspepsia Index - Korean version, Functional Dyspepsia-Related Quality of Life questionnaire, Ways of Coping Questionnaire, Coping Strategies Questionnaire, perception of bodily sensation questionnaire, State-Trait Anxiety Inventory, and the Center for Epidemiological Studies - Depression Scale. The outcomes will be evaluated before and after the treatment. DISCUSSION This is the first large-scale trial evaluating the efficacy and mechanism of acupuncture with fMRI and metabolomic methods. We will compare real acupuncture with the Streitberger sham needle to verify the specific effect of acupuncture. The results of this trial are expected to be relevant evidences affecting policy and decision-makers associated with routine healthcare.

Abstract
OBJECTIVES Measures of health-related quality of life (HRQOL) in chronic esophageal conditions such as gastroesophageal reflux disease, eosinophilic esophagitis, and achalasia are widely used to measure this important patient-reported outcome. We seek to leverage these existing measures to create a hybrid measure of esophageal illness HRQOL (the Northwestern Esophageal Quality of Life-NEQOL), allowing for broad use across diseases while maintaining sensitivity to nuances of a specific condition. METHODS A three-step, mixed-methods process per FDA guidelines for patient-reported outcome (PRO) development was followed: review and consolidation of existing HRQOL measure items into a single questionnaire, reliability and validity analyses (principle components factor analysis, Cronbach alpha, Guttman split-half, inter-item correlation, test-retest correlation, and Pearson's correlation with related constructs) based on responses from a representative sample of esophageal illness patients, and individual structured cognitive interviews with patients for item refinement and reduction. RESULTS An initial 30-item measure was created. Two-hundred twelve patients completed the reliability and validity portion of the study, and 15 completed cognitive interviews. Factor analysis and item-reduction resulted in 11 items being removed from the NEQOL prior to patient interviews. Construct validity was supported by moderate and significant correlations with psychological distress and general HRQOL. Test-retest reliability was excellent. Following patient interviews, an additional 5 items were removed because of floor effects or participant feedback yielding a 14-item, single scale measure of HRQOL. CONCLUSIONS Although more research is warranted, the NEQOL is a reliable and a valid hybrid measure of disease-specific HRQOL across several chronic esophageal conditions.

Discrepancies between upper GI symptoms described by those who have them and their identification by conventional medical terminology: a survey of sufferers in four countries.

Abstract
OBJECTIVE The objective of this study was to develop a self-administered questionnaire for upper gastrointestinal (GI) symptoms using lay vocabulary uninfluenced by established medical terminology or concepts and to conduct a survey of symptom occurrence among sufferers in four countries. METHODS The questionnaire was designed by integrating information gained from the vocabulary used by 38 upper GI symptom sufferers. There was no medical input to its development. The questionnaire was then used, after appropriate translation, in Brazil, Russia, the UK and the USA. Details of 10 659 symptom episodes were obtained from 2665 individuals. RESULTS Nine symptoms described in lay vocabulary were identified during questionnaire development. Of these, one corresponded to regurgitation, whereas two that were distinguished by survey participants might both be interpreted as heartburn. One chest symptom for which a corresponding medical term was uncertain occurred in ∼30% of the respondents. Five different 'stomach' or abdominal symptoms were identified. The predominant symptom and the pattern of concurrent symptoms often varied from one symptom episode to another. Use of the terms 'heartburn', 'reflux', 'indigestion' and 'burning stomach' to describe symptoms varied between countries. CONCLUSION Some common upper GI symptoms described by those who suffer them have no clear counterpart in conventional medical terminology. Inadequacy of the conventional terminology in this respect deserves attention, first, to characterize it fully, and thereafter to construct enquiry that delivers more precise symptom identification. Our results suggest that improvement may require the use of vocabulary of individuals suffering the symptoms without imposing conformity with established symptom concepts.

Abstract
Background Health-related quality of life (HRQOL) is an important outcome indicator for chronic disease, and particularly in the absence of biological markers for illness, such as with irritable bowel syndrome (IBS). The aims of this study were to develop and evaluate a new IBS-specific HRQOL instrument (IBS-HR-QOL). Methods This methodological study comprised three steps: conceptualization of the IBS-HR-QOL, item extraction and establishment of content validity, and psychometric evaluation of the instrument with 267 IBS patients recruited from four university hospitals. Results The content validity of the developed IBS-HR-QOL was assessed by 11 experts. Exploratory and confirmatory factor analyses yielded four factors. The criterion and convergent validities of the IBS-HR-QOL were demonstrated using the Short Form-36 and the Hospital Anxiety and Depression Scale, respectively. Known-groups validity was demonstrated using a symptom-severity scale. The internal consistency reliability and test-retest reliability were satisfactory, with a Cronbach’s alpha and intraclass correlation coefficient of 0.93 and 0.88, respectively. Conclusions The IBS-HR-QOL comprises a total of 16 items. The IBS-HR-QOL demonstrated good psychometric properties. This instrument is easily comprehensible and short, rendering it feasible for use in clinical practice and research.

Abstract
AIMS To investigate the clinical features, appetite, quality of life (QOL), and their associated psychological factors of functional dyspepsia (FD) patients with weight loss. METHODS For a multicenter study, FD patients were recruited and divided into two groups according to the degree of weight changes during the previous 12 months or less with the onset of dyspepsia symptoms: Group A (≥5%) and Group B (<5%). Patients were evaluated based on the Nepean dyspepsia index (NDI), appetite questionnaire, Hamilton Rating Scale of Anxiety/Depression (HAMA/HAMD). RESULTS The body mass index in Group A was lower than in Group B, while, the frequency of physician visits in Group A was higher than in Group B. There were no differences in the total scores of NDI-symptom checklist or the items of intensity and bothersomeness between them (p > 0.05), but the frequency item for Group A was significantly higher than Group B (p = 0.035). The incidence of anxiety or depression, the proportion of poor or very poor appetite for Group A was higher than those for Group B (p < 0.05). Subscale scores of the NDI-QOL for Group A were significantly lower than those for Group B (p < 0.05). CONCLUSIONS FD patients with weight loss have lower BMI, more frequent physician visits, higher psychological disorders, poorer appetite and QoL.

Brain-Gut Axis Modulation of Acupuncture in Functional Dyspepsia: A Preliminary Resting-State fcMRI Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:860463. [PMID: 26649064 PMCID: PMC4655049 DOI: 10.1155/2015/860463] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2015] [Accepted: 09/20/2015] [Indexed: 12/14/2022]
Abstract
Objective. To explore acupuncture effects on brain functional connectivity in patients with functional dyspepsia (FD). Methods. Eight patients in an acupuncture treatment group and ten healthy adults in the control group participated in the study. Acupuncture effectiveness was evaluated based on changes of the gastrointestinal symptoms, gastric motility measurements, and gastrin levels and comparisons with the control group when appropriate. To investigate functional connectivity changes related to FD and potential modulation after acupuncture, a set of regions of interest (ROIs) were selected according to previous fMRI reports of acupuncture. Results. Patients showed significant improvements of FD signs and symptoms after acupuncture treatments. For all of the ROIs, we identified subportions of the networks showing reduced connectivity in patients with FD. Connectivity between the ROIs and corresponding disease targets showed significant improvement after acupuncture treatment (P < 0.05) in all ROIs except for right medial temporal lobe-hippocampus and right inferior parietal lobule. Conclusion. Functional connectivity of the brain is changed in patients with FD but approximates that in healthy control after acupuncture treatment. The relief of gastrointestinal signs and symptoms by acupuncture is likely due to the normalization of brain-gut axis associated with FD.

Abstract
Background/Aims Weight loss is a recognized alarm symptom for organic gastrointestinal (GI) disease, yet the association between weight change (loss or gain) and specific GI symptoms remains poorly described. We assess the associations between GI symptoms and weight change in a population-based sample of Australian adults. Methods The prevalence of 26 GI symptoms was determined by a postal survey to 5000 residents in western Sydney, Australia (60% response rate). These were classified a priori into 5 symptom groups–abdominal pain, esophageal symptoms, dysmotility symptoms, diarrhea and constipation. Weight change was measured by two items which assessed weight loss and weight gain. Clinically relevant weight change was defined as a loss or gain of 3 or more kilograms in the past 3 months. Results Prevalence estimates for clinically relevant weight loss and gain in the past 3 months were 10.3% and 8.1%, respectively. When the 5 symptom groups were evaluated simultaneously, the dysmotility symptoms of fullness after meals emerged as a predictor of both weight loss (OR, 1.57; 95% CI, 1.32–1.88; P < 0.001) and weight gain (OR, 0.85; 95% CI, 0.72–0.99; P = 0.040), which also included bloating (OR, 1.64; 95% CI 1.46–1.84; P < 0.001). The associations remained significant following adjustment for socio-economic status, body mass index, and eating behaviors. Conclusions Specific dysmotility symptoms are independently predictive of both weight loss and weight gain. Different pathogenic mechanisms may be involved.

Abstract
UNLABELLED Few instruments have been developed and validated for the evaluation of multi-dimensional GI symptoms. The Gastrointestinal Symptoms Severity Index (GISSI), a multi-dimensional, self-report instrument, was designed as a brief measure of the frequency, severity, and bothersomeness of individual GI and pelvic floor/urogynecologic symptoms. AIM To report the psychometric properties of the GISSI subscales, including factorial structure, validity, and internal consistency. METHODS The GISSI included 32 items that assessed upper and lower GI symptoms and seven items related to pelvic floor/urogynecologic symptoms. A total of 934 patients presenting for upper and lower GI complaints completed the questionnaire between January 2013 and December 2013. The sample was randomly split into derivation (n = 466) and validation datasets (n = 468). A non-patient sample of 200 was collected separately. RESULTS Exploratory factor analysis supported a six-factor model for the derivation sample that accounted for 69.3 % of the total variance. The six GI symptom clusters were labeled as constipation/difficult defecation (five items), abdominal pain/discomfort (four items), dyspepsia (four items), diarrhea/anal incontinence (four items), GERD/chest symptoms (four items), and nausea/vomiting (two items). Inclusion of additional items related to female pelvic floor/urogynecologic symptoms resulted in a separate factor. Confirmatory factor analysis of the validation dataset supported the a priori hypothesized six-factor measurement model (Χ (2)(428) = 1462.98; P < 0.001; GFI = .88; RMSEA = .051). CONCLUSION The GISSI demonstrated good to excellent psychometric properties and provided multi-dimensional scaling of prominent GI symptom clusters. Further validation may provide an efficient, valid, and reliable measure of patient-reported clinical outcomes.

Abstract
BACKGROUND & AIMS Antidepressants are frequently prescribed to treat functional dyspepsia (FD), a common disorder characterized by upper abdominal symptoms, including discomfort or postprandial fullness. However, there is little evidence of the efficacy of these drugs in patients with FD. We performed a randomized, double-blind, placebo-controlled trial to evaluate the effects of antidepressant therapy on symptoms, gastric emptying (GE), and meal-induced satiety in patients with FD. METHODS We performed a study at 8 North American sites of patients who met the Rome II criteria for FD and did not have depression or use antidepressants. Patients (n = 292; 44 ± 15 years old, 75% were female, 70% with dysmotility-like FD, and 30% with ulcer-like FD) were randomly assigned to groups given placebo, 50 mg amitriptyline, or 10 mg escitalopram for 10 weeks. The primary end point was adequate relief of FD symptoms for ≥5 weeks of the last 10 weeks (of 12). Secondary end points included GE time, maximum tolerated volume in Nutrient Drink Test, and FD-related quality of life. RESULTS An adequate relief response was reported by 39 subjects given placebo (40%), 51 given amitriptyline (53%), and 37 given escitalopram (38%) (P = .05, after treatment, adjusted for baseline balancing factors including all subjects). Subjects with ulcer-like FD given amitriptyline were >3-fold more likely to report adequate relief than those given placebo (odds ratio = 3.1; 95% confidence interval: 1.1-9.0). Neither amitriptyline nor escitalopram appeared to affect GE or meal-induced satiety after the 10-week period in any group. Subjects with delayed GE were less likely to report adequate relief than subjects with normal GE (odds ratio = 0.4; 95% confidence interval: 0.2-0.8). Both antidepressants improved overall quality of life. CONCLUSIONS Amitriptyline, but not escitalopram, appears to benefit some patients with FD, particularly those with ulcer-like (painful) FD. Patients with delayed GE do not respond to these drugs. ClinicalTrials.gov ID: NCT00248651.

Abstract
In order to investigate the therapeutic potential of acupuncture on patients with functional dyspepsia (FD), patients were randomized to receive acupuncture at classic acupoints with manipulations (treatment group) versus acupuncture at nonacupoints without manipulation (control group) once every other day, three times a week, for one month and were followed up for three months. The primary outcomes included dyspeptic symptoms, quality of life, and mental status. The secondary outcomes included the fasting serum gastrin concentration, and frequency and propagation velocity of gastric slow waves. Sixty patients with FD were included, among whom, four dropped out. After one month's treatment, patients with FD showed significant improvements in primary (in both groups) and secondary (in the eight patients of the treatment group) outcomes as compared with baseline (P = 0.0078 to <0.0001); treatment group has better outcomes in all primary outcome measures (P < 0.0001 except for SDS (P = 0.0005)). Improvements on dyspeptic symptoms persist during follow-up (better in the treatment group). Acupuncture with manual manipulation had better effects on improving dyspeptic symptoms, mental status, and quality of life in patients with FD. These effects may be related to the increased frequency and propagation speed of gastric slow waves and serum gastrin secretion.

Abstract
OBJECTIVES The use of acupuncture treatment (AT) for functional dyspepsia is increasing, particularly in Asia. However, the efficacy of AT and its side effects have not been assessed. We performed a systematic review and meta-analysis of studies related to the effectiveness of AT for functional dyspepsia. DESIGN This study is a systemic review and meta-analysis. Seven electronic databases, including those in the English and Chinese languages, were systematically searched for randomized controlled trials of AT for functional dyspepsia through November 2012. There were no language restrictions. SETTING Randomized controlled trials (RCT) AT compared with placebo control or a comparative intervention were considered. The methodological qualities of the studies were evaluated using the risk of bias (ROB). Subgroups were analyzed according to the kinds of controls. MAIN OUTCOME MEASURES The primary outcomes were symptom scores. These included visual analogue scale (VAS) and Nepean Dyspepsia Index (NDI). Secondary outcomes were the total effective rate and adverse effects. RESULTS Twenty studies, including 1423 individual cases, were systematically reviewed. The risk of bias was high. Compared to sham AT, AT was associated with a significant positive effect in patients with functional dyspepsia (2.66, 95% CI 1.85-3.82). AT also improved symptoms for functional dyspepsia (1.18, 95% CI 1.01-2.60) compared to GI tract regulators on total effective rate. In addition, two articles produced a scale in favor of AT compared to medication (0.54, 95% CI 0.18-0.90). Two RCTs reported minimal AT-related adverse events. CONCLUSIONS The evidence suggests that AT is effective for functional dyspepsia. However, well-planned, long-term studies are necessary to evaluate the efficacy of AT for functional dyspepsia.

Abstract
Background/Aims Therapies of functional dyspepsia (FD) are limited. DA-9701 is a novel prokinetic agent formulated with Pharbitis semen and Corydalis Tuber. We aimed to assess the efficacy of DA-9701 compared with itopride in FD patients. Methods Patients with FD randomly received either itopride 50 mg or DA-9701 30 mg t.i.d after a 2-week baseline period. After 4 weeks of treatment, 2 primary efficacy endpoints were analyzed: the change from baseline in composite score of the 8 dyspeptic symptoms and the overall treatment effect. Impact on patients’ quality of life was assessed using the Nepean Dyspepsia Index (NDI) questionnaire. Results We randomly assigned 464 patients with 455 having outcome data. The difference of the composite score change of the 8 symptoms between the 2 groups was 0.62, indicating that DA-9701 was not inferior to itopride. The overall treatment effect response rate was not different between the groups. When responder was defined as ≥ 5 of the 7 Likert scale, responder rates were 37% of DA-9701 and 36% of itopride group. Patients receiving DA-9701 experienced similar mean percentage of days with adequate relief during the 4-week treatment period compared with those receiving itopride (56.8% vs 59.1%). Both drugs increased the NDI score of 5 domains without any difference in change of the NDI score between the groups. The safety profile of both drugs was comparable. Conclusions DA-9701 significantly improves symptoms in patients with FD. DA-9701 showed non-inferior efficacy to itopride with comparable safety.

Abstract
BACKGROUND Previous studies summarized altered brain functional patterns in functional dyspepsia (FD) patients, but how the brain structural patterns are related to FD remains largely unclear. The objective of this study was to determine the brain structural characteristics in FD patients. METHODS Optimized voxel-based morphometry and tract-based spatial statistics were employed to investigate the changes in gray matter (GM) and white matter (WM) respectively in 34 FD patients with postprandial distress syndrome and 33 healthy controls based on T1-weighted and diffusion-weighted imaging. The Pearson's correlation evaluated the link among GM alterations, WM abnormalities, and clinical variables in FD patients. The optimal brain structural parameters for identifying FD were explored using the receiver operating characteristic curve. KEY RESULTS Compared to controls, FD patients exhibited a decrease in GM density (GMD) in the right posterior insula/temporal superior cortex (marked as pINS), right inferior frontal cortex (IFC), and left middle cingulate cortex, and an increase in fractional anisotropy (FA) in the posterior limb of the internal capsule, posterior thalamic radiation, and external capsule (EC). Interestingly, the GMD in the pINS was significantly associated with GMD in the IFC and FA in the EC. Moreover, the EC adjacent to the pINS provided the best performance for distinguishing FD patients from controls. CONCLUSIONS & INFERENCES Our results showed pINS-related structural abnormalities in FD patients, indicating that GM and WM parameters were not affected independently. These findings would lay the foundation for probing an efficient target in the brain for treating FD.

Abstract
Objective. Functional dyspepsia (FD) is a frequent clinical finding in western world. The aim of this study is to compare the efficacy of a ginger and artichoke supplementation versus placebo in the treatment of FD. Methods. A prospective multicentre, double blind, randomized, placebo controlled, parallel-group comparison of the supplement and placebo over a period of 4 weeks was performed. Two capsules/day were supplied (before lunch and dinner) to 126 FD patients (supplementation/placebo: 65/61). Results. After 14 days of treatment, only supplementation group (SG) showed a significant amelioration (SG: α S = +1.195 MCA score units (u), P = 0.017; placebo: α P = +0.347 u, P = 0.513). The intercept (α) resulted to be significantly higher in SG than in placebo (α S - α P = +0.848 u, P < 0.001). At the end of the study, the advantage of SG versus placebo persists without variation (β S - β P = +0.077 u, P = 0.542). In SG, a significant advantage is observed for nausea (β S - β P = -0.398 u, P < 0.001), epigastric fullness (β S - β P = -0.241, P < 0.001), epigastric pain (β S - β P = -0.173 u, P = 0.002), and bloating (β S - β P = -0.167 u, P = 0.017). Conclusions. The association between ginger and artichoke leaf extracts appears safe and efficacious in the treatment of FD and could represent a promising treatment for this disease.

Abstract
AIM: To explore the incidence and psychological and behavioral characteristics of refractory functional dyspepsia (RFD) in China.
METHODS: The subjects of this study were 1341 new outpatients with functional dyspepsia (FD) who were diagnosed according to the Rome III criteria at four hospitals in Guangdong Province between June and September 2012, and 100 healthy volunteers. All subjects completed questionnaires and scales administered.
RESULTS: Three-hundred and twenty-seven of the 1341 patients with FD had RFD (24.4%). Patients with RFD had a longer disease duration and a more severe form of the disease than patients with non-refractory FD (NRFD). The prevalence of depression and anxiety symptoms was higher in patients with RFD than in patients with NRFD. The prevalence of unhealthy eating behaviors, lack of physical activity, and sleeping disorders was higher in patients with RFD than in patients with NRFD. Patients with RFD sought medical advice on more occasions and spent more money on treatment than patients with NRFD. Finally, patients with RFD had poorer quality of life than patients with NRFD.
CONCLUSION: RFD is not rare in clinical practice and should get attention by patients and doctors because of its long duration, severe symptoms, and associations with abnormal psychology and poor quality of life.

Complicated and uncomplicated peptic ulcer disease: altered symptom response to a nutrient challenge linked to gastric motor dysfunction. Digestion 2015; 89:239-46. [PMID: 24903331 DOI: 10.1159/000360635] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2013] [Accepted: 02/16/2014] [Indexed: 02/04/2023]
Abstract
BACKGROUND Bleeding peptic ulcer (BPU) frequently occurs in the absence of preceding dyspeptic symptoms. We have observed that patients with BPU had a diminished symptom response to nutrient challenge test compared to uncomplicated peptic ulcer disease (uPUD). We postulated that more symptoms are manifest in patients with uPUD than BPU because there are greater derangements in gastric motor function. AIM To assess gastric emptying in patients with BPU, uPUD and healthy controls (HC). METHODS We studied 17 patients with BPU, 10 with uPUD, and 15 HC. After an 8-hour fast, subjects ingested 200 ml of an enteral feeding solution, containing 5 MBq (99m)Tc-rhenium sulphide colloid, every 5 min up to a cumulative volume of 800 ml. Gastric emptying was measured by scintigraphy for the total, proximal and distal stomach. RESULTS Patients with uPUD had significantly higher gastric retention in the proximal and total stomach at 100 min than HC and BPU, while BPU had similar percent retention to HC. Patients with uPUD had significantly higher cumulative symptom response to the nutrient challenge than did HC and BPU, while BPU had similar symptom responses to HC. CONCLUSIONS Patients with uPUD have significantly delayed gastric emptying compared to HC and BPU. Data suggest that in addition to alterations of visceral sensory function, altered gastric motor function occurs during a nutrient challenge in uPUD but not BPU. Gastric motor function may contribute to the manifestation of dyspeptic symptoms in PUD.

Abstract
Background/Aims Increasing evidence shows involvement of psychological disorders in functional dyspepsia (FD), but how psychological factors exert their influences upon FD remains largely unclear. The purpose of the present study was to explore the brain-based correlations of psychological factors and FD. Methods Based on Fluorine-18-deoxyglucose positron emission tomography-computed tomography, the altered cerebral glycometabolism was investigated in 40 FD patients compared with 20 healthy controls during resting state using statistical parametric mapping software. Results FD patients exhibited increased glucose metabolism in multiple regions relative to controls (P < 0.001, family-wise error corrected). After controlling for the dyspeptic symptoms, increased aberrations persisted within the insula, anterior cingulate cortex (ACC), middle cingulate cortex (MCC) and middle frontal cortex (midFC), which was related to anxiety and depression score. Interestingly, FD patients without anxiety/depression symptoms also showed increased glycometabolism within the insula, ACC, MCC and midFC. Moreover, FD patients with anxiety/depression symptoms exhibited more significant hypermetabolism within the above 4 sites compared with patients without anxiety/depression symptoms. Conclusions Our results suggested that the altered cerebral glycometabolism may be in a vicious cycle of psychological vulnerabilities and increased gastrointestinal symptoms.

Increased nutrient sensitivity and plasma concentrations of enteral hormones during duodenal nutrient infusion in functional dyspepsia. Am J Gastroenterol 2014; 109:1910-20; quiz 1909, 1921. [PMID: 25403365 PMCID: PMC4365900 DOI: 10.1038/ajg.2014.330] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2014] [Accepted: 08/01/2014] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Functional dyspepsia is predominantly attributed to gastric sensorimotor dysfunctions. The contribution of intestinal chemosensitivity to symptoms is not understood. We evaluated symptoms and plasma hormones during enteral nutrient infusion and the association with impaired glucose tolerance and quality-of-life (QOL) scores in patients with functional dyspepsia vs. healthy controls. METHODS Enteral hormonal responses and symptoms were measured during isocaloric and isovolumic dextrose and lipid infusions into the duodenum in 30 patients with functional dyspepsia (n=27) or nausea and vomiting (n=3) and 35 healthy controls. Infusions were administered in randomized order over 120 min each, with a 120-min washout. Cholecystokinin, glucose-dependent insulinotropic peptide, glucagon-like peptide 1 (GLP1), and peptide YY were measured during infusions. RESULTS Moderate or more severe symptoms during lipid (4 controls vs. 14 patients) and dextrose (1 control vs. 12 patients) infusions were more prevalent in patients than controls (P≤0.01), associated with higher dyspepsia symptom score (P=0.01), worse QOL (P=0.01), and greater plasma hormone concentrations (e.g., GLP1 during lipid infusion). Moderate or more severe symptoms during enteral infusion explained 18%, and depression score explained 21%, of interpatient variation in QOL. Eight patients had impaired glucose tolerance, associated with greater plasma GLP1 and peptide YY concentrations during dextrose and lipid infusions, respectively. CONCLUSIONS Increased sensitivity to enteral dextrose and lipid infusions was associated with greater plasma enteral hormone concentrations, more severe daily symptoms, and worse QOL in functional dyspepsia. These observations are consistent with the hypothesis that enteral hormones mediate increased intestinal sensitivity to nutrients in functional dyspepsia.

Abstract
BACKGROUND/AIMS DA-9701 (Motilitone) is a new prokinetic agent formulated with Corydalis Tuber and Pharbitis Seed. We assessed the efficacy of DA-9701 in symptomatic patients with minimal change esophagitis. METHODS Patients with minimal change esophagitis presenting with reflux or dyspeptic symptoms were randomly assigned to receive either DA-9701 30 mg or placebo t.i.d. (means 3 times a day). After 4 weeks of treatment, the primary efficacy end point determined by changes of the Nepean dyspepsia index questionnaire-Korean version (NDI-K) symptom scores, was analyzed. RESULTS Forty-two and 39 patients were assigned to the treatment and control groups, respectively. After 4 weeks, NDI-K symptom scores were reduced from 35.4 to 13.5 (P < 0.001) and from 43.0 to 27.7 (P < 0.001) in the treatment and the control groups, respectively. However, changes in the symptom scores did not differ between the 2 groups (P = 0.741). Although the quality of life scores were significantly improved after 4 weeks in both groups, changes in the quality of life score between the baseline value and that at 4 weeks did not differ between the 2 groups. The reflux symptom score was significantly improved in the treatment group compared to the placebo group in patients aged 65 years or older (P = 0.035). CONCLUSIONS Although NDI-K symptom scores and quality of life scores were improved after 4 weeks of treatment compared with baseline values in patients with minimal change esophagitis, DA-9701 did not improve the symptom scores or quality of life scores compared with the placebo.

Abstract
PURPOSE This study conducted a systematic review of the methodological quality of the psychometric evaluation process and the quality of measurement properties of rheumatoid arthritis (RA)-specific health-related quality-of-life (HRQOL) questionnaires with the purpose of obtaining the best evidence to help in the selection of the most appropriate instrument for measuring HRQOL in RA patients. METHODS A systematic literature search was performed to identify RA-specific HRQOL questionnaires in databases. The methodological quality of the studies was assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments checklist. The quality of the measurement properties was assessed using quality criteria. The evidence regarding the measurement properties was pooled using best-evidence synthesis, with considerations of the number and methodological quality of the studies, and the consistency of their findings in terms of the quality of the measurement properties. RESULTS The search identified 37 studies describing 9 instruments. Best-evidence synthesis suggested that the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire had the strongest positive evidence, especially with respect to reliability, measurement error, and content validity, and moderate positive evidence with respect to hypothesis testing and responsiveness. CONCLUSIONS The current evidence suggests that the best-validated instrument among the RA-specific HRQOL measures is the RAQoL questionnaire in terms of both methodological quality in the process of psychometric evaluation and the quality of the measurement properties. However, there is limited evidence regarding internal consistency and structural validity of the RAQoL. Further efforts are warranted to establish the psychometric quality of this questionnaire.

Abstract
BACKGROUND Increasing evidence shows central abnormalities in functional dyspepsia (FD) patients, but whether the symptom severity is directly reflected in altered brain patterns remains unclear. The purpose of this study was to explore how FD affected the resting functional brain patterns for different degrees of symptom severity. METHODS Functional magnetic resonance imaging was carried out in 40 FD patients and 20 healthy controls. The resting-state brain changes in regional homogeneity (ReHo) and seed correlation analysis were investigated in patients relative to controls. To what degree the brain changes reflected the severity of the disease was assessed by a pattern classification technique. KEY RESULTS Altered ReHo values (p < 0.05, FDR corrected) were discovered in multiple brain areas in FD patients, and only the anterior cingulate cortex (ACC) and thalamus exhibited significant correlation with the severity of dyspepsia symptoms. Compared with controls, the neural signal changes of the thalamus were not found in the less severe FD patient group but in the relatively more severe group, while the ACC showed aberrations in both groups. Seed-based correlation analysis revealed ACC- and thalamus-related functional connectivity differences between FD patients and controls at a voxel-wise level, and the altered thalamic circuits provided the best performance in distinguishing FD patients with different levels of symptom severity. CONCLUSIONS & INFERENCES Our results indicated that the functional abnormalities of the ACC and thalamus may occur at different clinical courses in FD. This may help us better understand the progression of FD.

Abstract
Background Functional dyspepsia (FD) is a common health problem currently without any optimal treatments. Acupuncture has been traditionally sought as a treatment for FD. The aim of this study is to investigate whether acupuncture treatment helps improve symptoms of FD. Methods/design A two-center, randomized, waitlist-controlled trial will be carried out to evaluate whether acupuncture treatment improves FD symptoms. Seventy six participants aged 18 to 75 years with FD as diagnosed by Rome III criteria will be recruited from August 2013 to January 2014 at two Korean Medicine hospitals. They will be randomly allocated either into eight sessions of partially individualized acupuncture treatment over 4 weeks or a waitlist group. The acupuncture group will then be followed-up for 3 weeks with six telephone visits and a final visit will be paid at 8 weeks. The waitlist group will receive the identical acupuncture treatment after a 4-week waiting period. The primary outcome is the proportion of responders with adequate symptom relief and the secondary outcomes include Nepean dyspepsia index, EQ-5D, FD-related quality of life, Beck’s depression inventory, state-trait anxiety inventory questionnaire, and level of ghrelin hormone. The protocol was approved by the participating centers’ Institutional Review Boards. Discussion Results of this trial will help clarify not only whether the acupuncture treatment is beneficial for symptom improvement in FD patients but also to elucidate the related mechanisms of how acupuncture might work.

Abstract
OBJECTIVES Because gastrointestinal (GI) illnesses can cause physical, emotional, and social distress, patient-reported outcomes (PROs) are used to guide clinical decision making, conduct research, and seek drug approval. It is important to develop a mechanism for identifying, categorizing, and evaluating the over 100 GI PROs that exist. Here we describe a new, National Institutes of Health (NIH)-supported, online PRO clearinghouse-the GI-PRO database. METHODS Using a protocol developed by the NIH Patient-Reported Outcome Measurement Information System (PROMIS(®)), we performed a systematic review to identify English-language GI PROs. We abstracted PRO items and developed an online searchable item database. We categorized symptoms into content "bins" to evaluate a framework for GI symptom reporting. Finally, we assigned a score for the methodological quality of each PRO represented in the published literature (0-20 range; higher indicates better). RESULTS We reviewed 15,697 titles (κ>0.6 for title and abstract selection), from which we identified 126 PROs. Review of the PROs revealed eight GI symptom "bins": (i) abdominal pain, (ii) bloat/gas, (iii) diarrhea, (iv) constipation, (v) bowel incontinence/soilage, (vi) heartburn/reflux, (vii) swallowing, and (viii) nausea/vomiting. In addition to these symptoms, the PROs covered four psychosocial domains: (i) behaviors, (ii) cognitions, (iii) emotions, and (iv) psychosocial impact. The quality scores were generally low (mean 8.88 ± 4.19; 0 (min)-20 (max). In addition, 51% did not include patient input in developing the PRO, and 41% provided no information on score interpretation. CONCLUSIONS GI PROs cover a wide range of biopsychosocial symptoms. Although plentiful, GI PROs are limited by low methodological quality. Our online PRO library (www.researchcore.org/gipro/) can help in selecting PROs for clinical and research purposes.

Abstract
BACKGROUND Few useful patient-reported outcomes scales for functional dyspepsia exist in China. AIMS The purpose of this work was to translate and cross-culturally adapt the Functional Digestive Disorders Quality of Life Questionnaire (FDDQL) from the English version to Chinese (in Mandarin). METHODS The following steps were performed: forward translations, synthesis of the translations, backward translations, pre-testing and field testing of FDDQL. Reliability, validity, responsiveness, confirmatory factor analysis, item response theory and differential item functioning of the scale were analyzed. RESULTS A total of 300 functional dyspepsia patients and 100 healthy people were included. The total Cronbach's alpha was 0.932, and split-half reliability coefficient was 0.823 with all test-retest coefficients greater than 0.9 except Coping With Disease domain. In construct validity analysis, every item correlated higher with its own domain than others. The comparative fit index of FDDQL was 0.902 and root mean square error of approximation was 0.076. Functional dyspepsia patients and healthy people had significant differences in all domains. After treatment, all domains had significant improvements except diet. Item response theory analysis showed the Person separation index of 0.920 and the threshold estimator of items was normally distributed with a mean of 0 and standard deviation of 1.27. The residuals of each item were between -2.5 and 2.5, without statistical significance. Differential item functioning analysis found that items had neither uniform nor non-uniform differential item functioning in different genders and age groups. CONCLUSIONS The Chinese version of FDDQL has good psychometric properties and is suitable for measuring the health status of Chinese patients with functional dyspepsia.

Abstract
Numerous questionnaires with a wide variety of characteristics have been developed for the assessment of gastroesophageal reflux disease (GERD). Four well-defined dimensions are noticeable in these GERD questionnaires, which are symptoms, response to treatment, diagnosis, and burden on the quality of life of GERD patients. The aim of this review is to develop a complete overview of all available questionnaires, categorized per dimension of the assessment of GERD. A systematic search of the literature up to January 2013 using the Pubmed database and the Embase database, and search of references and conference abstract books were conducted. A total number of 65 questionnaires were extracted and evaluated. Thirty-nine questionnaires were found applicable for the assessment of GERD symptoms, three of which are generic gastrointestinal questionnaires. For the assessment of response to treatment, 14 questionnaires were considered applicable. Seven questionnaires with diagnostic purposes were found. In the assessment of quality of life in GERD patients, 18 questionnaires were found and evaluated. Twenty questionnaires were found to be used for more than one assessment dimension, and eight questionnaires were found for GERD assessment in infants and/or children. A wide variety of GERD questionnaires is available, of which the majority is used for assessment of GERD symptoms. Questionnaires differ in aspects such as design, validation and translations. Also, numerous multidimensional questionnaires are available, of which the Reflux Disease Questionnaire is widely applicable. We provided an overview of GERD questionnaires to aid investigators and clinicians in their search for the most appropriate questionnaire for their specific purposes.

Relationships between Pathological Patterns and Quality of Life: Pathway Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:453096. [PMID: 24288560 PMCID: PMC3830807 DOI: 10.1155/2013/453096] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/27/2013] [Revised: 09/06/2013] [Accepted: 09/07/2013] [Indexed: 11/18/2022]
Abstract
Purpose. The purpose of our study was to examine the relationships between pathological patterns and self-rated quality of life (QoL). Methods. A total of 426 Korean subjects participated in this study (male : female = 154 : 272). The subjects were asked to complete Yin Deficiency (YD), Qi Deficiency (QD), Food Stagnation (FS), Blood Stasis (BS), Phlegm, and Seven Emotions Impairment (SEI) pattern Questionnaires and the General Health Questionnaire (GHQ). We formed a pathway model consisting of pathological patterns and QoL questionnaire scores and examined which pathological patterns resulted in decreased QoL using path analysis. Results. Our pathway model had satisfactory fitness levels (GFI = 0.975, NFI = 0.984, and CFI = 0.984) and showed that Phlegm and SEI patterns directly resulted in decreased QoL, whereas QD, YD, FD, and BS indirectly resulted in decreased QoL. The pathway model suggested that the severity or stage of decreased QoL may be estimated by pathological patterns: QD and YD patterns are associated with the early stage; FS and BS patterns are associated with the middle stage; Phlegm and SEI are associated with the later stage of decreased QoL. Conclusion. Our results suggest that pathological patterns directly or indirectly affect decreases in QoL.

A traditional herbal formula, Hyangsa-Pyeongwi san (HPS), improves quality of life (QoL) of the patient with functional dyspepsia (FD): randomized double-blinded controlled trial. JOURNAL OF ETHNOPHARMACOLOGY 2013; 151:279-286. [PMID: 24239600 DOI: 10.1016/j.jep.2013.10.033] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2013] [Revised: 09/24/2013] [Accepted: 10/17/2013] [Indexed: 06/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hyangaa-Pyeongwi san is the most well known description in Traditional Chinese Medicine for treating functional gastrointestinal disorders. Functional dyspepsia (FD) is a main concern of intimidating quality of life (QoL) in recent days. Although many medicines have been developed to improve FD symptoms as well as QoL, there are no potential drugs and treatments for FD. The aim of this study is to investigate the effects of Hyangaa-Pyeongwi san (HPS) on QoL of patients with FD. METHODS This study was designed as a randomized, double blinded, placebo controlled, and parallel group trial. Participants received either placebo or HPS (9.68g of HPS at once, three times daily) for 4-weeks, and the efficacy evaluations were performed by assessing the Nepean Dyspepsia Index (NDI) and functional dyspepsia-quality of life (FD-QoL) at 0-, 4- and 8-weeks. RESULTS Total of 170 patients participated and were randomly allocated into placebo or HPS groups. Total symptom score of NDI decreased after 4-weeks trial in both groups (p>0.05). HPS significantly improved QoL scores, especially in the area of 'interference and eat/drink' in NDI (p=0.0031) as well as 'liveliness status', 'role-functioning status', and total score in FD-QoL (p=0.026 for liveliness status and p=0.035 for role-functioning status). This significant improvement of FD-QoL had lasted for 4-weeks. CONCLUSION HPS treatment is markedly effective in improving QoL in patients with FD. Moreover, we observed that this improvement had lasted for 4 weeks after finishing the trial through the follow-up study.

Abstract
Objective. This study was conducted for development and validation of the Sasang Digestive Function Inventory (SDFI) with type-specific digestive function-related symptoms for identification of Sasang type and pathological pattern. Methods and Materials. We selected questionnaire items for pathophysiological symptoms using internal consistency analysis and examined construct validity using 193 healthy participants. Test-retest reliability with a four-week interval as well as convergent validity was examined using the Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), Dutch Eating Behavior Questionnaire (DEBQ), and Body Mass Index (BMI). Results. The 21-item SDFI showed satisfactory internal consistency (Cronbach's alpha = 0.743) and test-retest reliability (r = 0.886, P < 0.001). Three extracted subscales, SDFI-Digestion, SDFI-Appetite, and SDFI-Eating pattern, explained 56.02% of the total variance. The SDFI showed significant (P < 0.001) correlation with total symptom score of NDIK, FDRQOL-Eating status, DEBQ-External Eating scale, and BMI. The SDFI score of the Tae-Eum (50.62 ± 8.05) type was significantly (P < 0.001) larger than that of the So-Eum (43.11 ± 11.26) type. Conclusion. Current results demonstrated the reliability and validity of the SDFI and its subscales, which can be utilized as an objective instrument for diagnosis of Sasang types and assessment of the type-specific digestive function.

Abstract
BACKGROUND Previous imaging studies on functional dyspepsia (FD) have focused on abnormal brain functions during special tasks, while few studies concentrated on the resting-state abnormalities of FD patients, which might be potentially valuable to provide us with direct information about the neural basis of FD. The main purpose of the current study was thereby to characterize the distinct patterns of resting-state function between FD patients and healthy controls (HCs). METHODOLOGY/PRINCIPAL FINDINGS Thirty FD patients and thirty HCs were enrolled and experienced 5-mintue resting-state scanning. Based on the support vector machine (SVM), we applied multivariate pattern analysis (MVPA) to investigate the differences of resting-state function mapped by regional homogeneity (ReHo). A classifier was designed by using the principal component analysis and the linear SVM. Permutation test was then employed to identify the significant contribution to the final discrimination. The results displayed that the mean classifier accuracy was 86.67%, and highly discriminative brain regions mainly included the prefrontal cortex (PFC), orbitofrontal cortex (OFC), supplementary motor area (SMA), temporal pole (TP), insula, anterior/middle cingulate cortex (ACC/MCC), thalamus, hippocampus (HIPP)/parahippocamus (ParaHIPP) and cerebellum. Correlation analysis revealed significant correlations between ReHo values in certain regions of interest (ROI) and the FD symptom severity and/or duration, including the positive correlations between the dmPFC, pACC and the symptom severity; whereas, the positive correlations between the MCC, OFC, insula, TP and FD duration. CONCLUSIONS These findings indicated that significantly distinct patterns existed between FD patients and HCs during the resting-state, which could expand our understanding of the neural basis of FD. Meanwhile, our results possibly showed potential feasibility of functional magnetic resonance imaging diagnostic assay for FD.

Abstract
Recent neuroimaging studies have shown local brain aberrations in functional dyspepsia (FD) patients, yet little attention has been paid to the whole-brain resting-state functional network abnormalities. The purpose of this study was to investigate whether FD disrupts the patterns of whole-brain networks and the abnormal functional connectivity could reflect the severity of the disease. The dysfunctional interactions between brain regions at rest were investigated in FD patients as compared with 40 age- and gender- matched healthy controls. Multivariate pattern analysis was used to evaluate the discriminative power of our results for classifying patients from controls. In our findings, the abnormal brain functional connections were mainly situated within or across the limbic/paralimbic system, the prefrontal cortex, the tempo-parietal areas and the visual cortex. About 96% of the subjects among the original dataset were correctly classified by a leave one-out cross-validation approach, and 88% accuracy was also validated in a replication dataset. The classification features were significantly associated with the patients' dyspepsia symptoms, the self-rating depression scale and self-rating anxiety scale, but it was not correlated with duration of FD patients (p>0.05). Our results may indicate the effectiveness of the altered brain functional connections reflecting the disease pathophysiology underling FD. These dysfunctional connections may be the epiphenomena or causative agents of FD, which may be affected by clinical severity and its related emotional dimension of the disease rather than the clinical course.

Abstract
Patient-generated reports, also known as Patient-Reported Outcomes (PROs), capture the patients' illness experience in a structured format and may help bridge the gap between patients and providers. PROs measure any aspect of patient-reported health (e.g., physical, emotional or social symptoms) and can help to direct care and improve clinical outcomes. When clinicians systematically collect patient-reported data in the right place at the right time, PRO measurement can effectively aid in detection and management of conditions, improve satisfaction with care and enhance the patient-provider relationship. This review article summarizes the latest approaches to PRO measuring for clinical trials and clinical practice, with a focus on use of PROs in gastroenterology.

Abstract
OBJECTIVES Recent neuroimaging studies have identified brain microstructural changes in patients with functional gastrointestinal disorders, especially in irritable bowel syndrome. However, whether the microstructure is changed in patients with postprandial distress syndrome (PDS) remains elusive. Therefore, the present study was aimed to examine the white-matter (WM) microstructural changes in patients with PDS. METHODS Diffusion tensor imaging (DTI) was performed on 36 PDS patients recruited according to the Rome III criteria and 36 healthy controls. Tract-based spatial statistics were adopted to examine the between-group differences in DTI measures including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity, and radial diffusivity (RD). The correlations between DTI measures and clinical variables were evaluated using a non-parametric permutation-based test. Multiple comparisons were corrected using the threshold-free cluster enhancement method. RESULTS The patient group showed increased FA along with reduced MD and RD in multiple WM tracts, including the corona radiata, internal capsule, posterior thalamic radiation, corpus callosum, external capsule, sagittal stratum, and superior longitudinal fasciculus (P<0.05, corrected). The inclusion of anxiety and depression as covariates abolished the between-group difference in these tracts with the exception of the corona radiata. The DTI measures were not found to be correlated with the severity of symptoms or the duration of disease (P>0.05, corrected). CONCLUSIONS Our findings have provided preliminary evidence of WM microstructural changes in patients with PDS. Part of the changes could be accounted for by a higher level of psychosocial distress in the patient group.
