RESUMO
BACKGROUND: Evidences of comparison of sex difference in Chinese irritable bowel syndrome (IBS) patients were few. We aim to compare gender difference in the biopsychosocial characteristics of Chinese patients of IBS predominant with diarrhea (IBS-D). METHODS: IBS-D patients meeting Rome III criteria were enrolled. We administered IBS symptom questionnaires, evaluation of psychological status (HAMD and HAMA scales) and IBS quality of life (IBS-QOL), dietary habits, healthcare seeking behaviors, and compared biopsychosocial characteristics between male and female patients. RESULTS: Four hundred and ninety patients were enrolled including 299 males and 191 females. More female patients reported abdominal pain associated with defecation (84.3% vs. 74.9%, P = 0.014) while males reported more abdominal discomfort (39.8% vs. 26.7%, P = 0.003). Females had higher IBS symptom score (9.7 ± 1.7 vs. 9.4 ± 1.4, P = 0.025) and more of females had severe abdominal pain/discomfort (17.8% vs. 12.4%, P = 0.013) while there were no significant differences of other bowel symptoms. Females reported higher incidence of comorbid anxiety state (64.9% vs. 52.8%, P = 0.008) and depression state (35.6% vs. 19.7%, P < 0.001) than males. Female patients also had lower IBS-QOL score (70.2 ± 20.4 vs. 75.1 ± 16.8, P = 0.028) and more frequent consultations, as well as less response for dietary modification than males. CONCLUSIONS: Chinese female patients with IBS-D had more prominent psychosocial disorders compared to male patients and their abdominal symptoms had minor differences.

INTRODUCTION: The therapeutic effect of probiotics for irritable bowel syndrome (IBS) was controversial. This study aims to evaluate the short-term efficacy of Bifidobacterium quadruple viable tablet in patients with diarrhea-predominant IBS and explore factors associated with response to probiotics. METHODS: A randomized, double-blind, placebo-controlled, multicenter trial was performed in 15 hospitals. A total of 290 patients who fulfilled the eligibility criteria were assigned to the probiotics or placebo group randomly with a ratio of 1:1 for a 4-week treatment and a 2-week follow-up. The primary outcome was the response rate. It was regarded as the proportion of patients with composite responses of improvement in both abdominal pain and diarrhea simultaneously. RESULTS: After 4-week continuous administration, the response rates of the probiotics and the placebo were 67.59% and 36.55%, respectively ( P < 0.001). In the probiotics, those with higher abdominal pain scores (2.674 [1.139-6.279]) were more likely to respond, but responders in placebo had lower Hamilton Depression Scale score (0.162 [0.060-0.439]), lower Hamilton Anxiety Scale score (0.335 [0.148-0.755]), and higher degree of bloating (2.718 [1.217-6.074]). Although the diversity of the microbiota was not significantly changed by probiotics, the abundance of bacteria producing short-chain fatty acids (SCFAs), including Butyricimonas ( P = 0.048), Pseudobutyrivibrio ( P = 0.005), Barnesiella ( P = 0.020), and Sutterella ( P = 0.020), and the concentration of SCFAs including butyric acid ( P = 0.010), valeric acid ( P = 0.019), and caproic acid ( P = 0.046) in feces increased. DISCUSSION: A Bifidobacterium quadruple viable tablet had a significant short-term efficacy for the treatment of diarrhea-predominant IBS and was more effective in patients with higher abdominal pain scores. This kind of probiotics could improve the abundance of several bacteria producing SCFAs and the concentration of fecal SCFAs compared with placebos.

Cross-cultural factors are important in functional gastrointestinal disorders (FGIDs). In the setting of FGIDs, the aims of this review were to: 1) engender interest in global aspects; 2) gain a clearer understanding of culture, race and ethnicity and their effect on patient care and research; 3) facilitate cross-cultural clinical and research competency; and 4) improve and foster the quality and conduct of cross-cultural, multinational research. Cultural variables are inevitably present in the physician-patient context. Food and diets, which differ among cultural groups, are perceived globally as related to or blamed for symptoms. From an individual perspective, biological aspects, such as genetics, the microbiome, environmental hygiene, cytokines and the nervous system, which are affected by cultural differences, are all relevant. Of equal importance are issues related to gender, symptom reporting and interpretation, and family systems. From the physician's viewpoint, understanding the patient's explanatory model of illness, especially in a cultural context, affects patient care and patient education in a multicultural environment. Differences in the definition and use of Complementary and Alternative Medicine and other issues related to healthcare services for the FGIDs are also a relevant cross-cultural issue. This paper highlights the importance of cross-cultural competence in clinical medicine and research.
RESUMO
BACKGROUND: Patients with irritable bowel syndrome (IBS) have significantly reduced quality of life (QOL). Although intestinal and extraintestinal symptoms, as well as comorbid psychological disorders, may reduce the QOL of IBS patients, the primary determinant of QOL in these patients remains unclear. This study aimed to identify the main factors affecting QOL in patients with IBS with diarrhea (IBS-D). METHODS: Consecutive patients meeting the Rome III Diagnostic Criteria for IBS-D were enrolled in this study. Patients with organic diseases were excluded. The intestinal symptoms, psychological states and QOL of these patients were evaluated using IBS-specific symptom questionnaires, the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA), and the Chinese version of the IBS-QOL instrument. Overall scores for intestinal symptoms were calculated by frequency and degree. RESULTS: This study enrolled 227 IBS-D patients, of mean age 44.68 ± 10.81 years. Their mean overall IBS-QOL score was 71.68 ± 18.54, with the lowest score being for food avoidance (53.71 ± 26.92). Overall IBS-QOL score correlated negatively with overall scores of intestinal symptoms and HAMD and HAMA scores (p < 0.001 each). Overall intestinal symptoms scores correlated negatively with HAMD and HAMA scores (p < 0.001 each). Scores of HAMD, HAMA and structural factors (i.e., anxiety/somatization, cognitive disorder, psychomotor retardation, psychic anxiety, and somatic anxiety) were significantly higher in female than in male patients (p < 0.01). Food avoidance and social reaction scores of female patients were significantly lower than those of male patients (p < 0.05 each). The degree of defecation urgency, frequency of passing mucus and psychomotor retardation were independent factors predicting reduced QOL in IBS-D patients. CONCLUSION: Intestinal symptoms and psychological factors jointly reduce the QOL of IBS-D patients, with gender differences in the impact of both factors on QOL.

OBJECTIVE: To identify the characteristics of esophageal motility abnormalities in patients with gastroesophageal reflux disease (GERD) and its influence on esophageal acid exposure. METHODS: Patients with typical reflux symptoms and diagnosis of reflux esophagitis (RE) or non-erosive reflux disease (NERD), and healthy subject were enrolled in this prospective controlled study. The esophageal manometry and esophageal 26 hours pH monitoring were performed. GERD patients were divided into 3 groups according to their esophageal motility abnormalities: â low lower esophageal sphincter pressure (LESP) group, â¡ ineffective esophageal motivation (IEM) group, ⢠IEM and low LESP group. Esophageal acid exposure was analyzed among different groups. RESULTS: A total of 27 GERD patients (15 RE, 12 NERD) and 10 healthy subjects were enrolled in this study. The esophageal motility abnormalities in GERD patients mainly presented as the decrease of LESP and distal esophageal body pressure. The proportion of 3 kinds of esophageal motility abnormalities has significant difference between RE and NERD patients (P = 0.017). In IEM and low LESP group, all patients suffered from RE, with the total number of acid exposure, the total acid exposure time and the acid exposure time in fasting higher than those in low LESP group [98.0 (63.3, 282.8) times vs 41.0 (25.0, 82.0) times, P = 0.029; 11.7% (4.1%, 30.0%) vs 2.2% (1.4%, 9.6%), P = 0.045; 2.6% (0.9%, 4.9%) vs 0.0 (0.0, 1.2%), P = 0.015]. CONCLUSIONS: Esophageal motility abnormalities in GERD patients are characterized as low LESP and IEM in distal esophagus. The coexistence of low LESP and IEM exacerbates esophageal acid exposure, which might explain the mechanism of esophageal mucosal injury in RE patients.

OBJECTIVE: To investigate the co-morbid state of mental disorder in patients with functional dyspepsia (FD) in a tertiary general hospital in China and explore the risk factors of the co-morbidity of FD and major depressive disorder (MDD). METHODS: This study was designed as a bilateral evaluation and structural psychiatric interview. Patients with FD and newly diagnosed outpatients with MDD in gastrointestinal and psychological departments were enrolled. FD was defined by Rome III criteria. The questionnaires including symptoms of FGIDs Roma III, the composite international diagnostic interview (CIDI 3.0) Chinese version, the Hamilton depression/anxiety rating scale (HAMD/HAMA), Montgomery-Asberg depression scale (MADRS) were involved in this study. All patients were administered by well trained physicians and investigators in face to face interview. RESULTS: A total of 69 patients have completed the valid questionnaires and interview, among whom 42 met FD criteria (FD group) and 27 with FD co-morbid MDD (co-morbid group). Male to female ratios were 17:25 and 10:17, the mean age (42.1 ± 13.3) and (43.1 ± 15.3) years respectively. The life-long co-morbidity of FD and MDD was 39.1% (27/69), while 31.9% (22/69) patients with FD were accompanied with other mental disorders rather than MDD. Patients in FD co-morbid MDD group had significantly more severe depression than those in FD group with HAMD-17 score 21.6±8.0 and 14.5 ± 7.6, HAMA score 21.2 ± 9.0 and 14.9 ± 7.5 respectively (all P<0.01). Logistic regression analysis showed that high score of MADRS and complication with functional anorectal disorder may be the risk factors of FD co-morbid MDD [OR(95% CI) 1.12(1.06-1.19) and 7.07(1.12-44.53)]. CONCLUSIONS: The co-morbidity rate of FD with MDD in our hospital is high. In addition to MDD, other mental disorders also need to be paid attention in FD patients. FD co-morbid MDD patients suffered more severe depression and anxiety. The high score of MADRS and complication with functional anorectal disorder seem to be the risk factors of co-morbidity of FD and MDD.

OBJECTIVE: To explore the characteristics of esophageal motility in patients with non-erosive disease (NERD) and reflux esophagitis (RE). METHODS: For this single-blind retrospective study, adult patients with typical reflux symptoms underwent esophageal manometry from January 2008 to December 2011. Their course of disease, age, gender, esophageal manometry, hiatal function and 24 h pH monitoring were analyzed by univariate and binary Logistic regression analyses. RESULTS: A total of 244 adult patients (RE = 85, NERD = 159) were enrolled into this study. Age and course of disease were significantly higher in RE group than those in NERD group ((50.7 ± 1.2) vs (46.5 ± 0.9) yrs,(4.8 ± 0.5) vs (3.4 ± 0.3) yrs, both P < 0.05) while no difference existed in gender (P > 0.05).Lower esophageal sphincter (LES) length, LES pressure, peristaltic contraction amplitude of distal esophageal body and rate of effective peristaltic contraction of distal esophageal body were significantly lower in RE group than those in NERD group ((1.91 ± 0.06) vs (2.19 ± 0.04) cm,(6.98 ± 0.31) vs (8.54 ± 0.31)mmHg,(56.76 ± 3.21) vs (75.57 ± 3.47) mmHg, 54.1% (46/85) vs 76.1% (121/159), all P < 0.05) . However, there was no inter-group difference in LES relaxation rate and upper esophageal sphincter (UES) function (both P > 0.05). Rate of hiatal hernia (HH) and hiatal flabby (HF) in RE group significantly increased versus NERD group (23.5% (20/85) vs 1.9% (3/159), 24.7% (21/85) vs 11.3% (18/159), both P < 0.05) . Positive rate of 24 h esophageal pH monitoring, reflux number and percent of reflux were significantly higher in RE group than those in NERD group (59.1% (26/44) vs 32.5% (38/117), 71.0 (13.5, 119.0) vs 25.0 (8.0, 56.0), 5.0% (0.4%, 10.9%) vs 1.1% (0.2%, 5.0%), all P < 0.05) . Binary Logistic regression analysis showed that LES length, rate of effective peristaltic contraction of distal esophageal body and HH were risk factors for RE (OR = 2.781,0.037, 21.722, 95%CI:1.057-7.313, 0.009-0.152, 5.433-86.845). CONCLUSIONS: Impaired anti-reflux barrier at esophagogastric junction and impaired clearance of esophageal body are important causative factors for RE. And abnormal anatomy in esophagogastric junction should raise alerts.

OBJECTIVE: To evaluate the effects of neoadjuvant chemoradiotherapy on anorectal function in patients with mid and low rectal cancer. METHODS: A total of 22 patients with mid and low rectal cancer were enrolled into this study from October 2012 to November 2013. There were 14 males and 8 females with a mean age of (59 ± 10) years. We collected the defecation-related symptoms with questionnaire interview and evaluated the anorectal function with three-dimensional high-resolution manometry before neoadjuvant chemoradiotherapy and at 6 weeks after radiotherapy. RESULTS: The defecation-related symptoms (including increase in stool frequency, change in stool form, hematochezia and urgency, etc.) improved significantly after neoadjuvant chemoradiotherapy (n = 21). Among those with lower rectal cancer (n = 8), the length of high-pressure zone in manometry increased significantly after neoadjuvant chemoradiotherapy ((3.84 ± 0.61) vs (2.96 ± 0.80) cm, P = 0.003). However, there was no significant change for other parameters in anorectal function (all P > 0.05). CONCLUSIONS: In patients with mid and low rectal cancer, neoadjuvant chemoradiotherapy may improve the defecation symptoms and enhance anal sphincter high-pressure zone for lower rectal cancer. And it is probably due to its tumor-downsizing effect.

BACKGROUND: This SRMA reviewed and assessed the changes in the severity of disorders of gut-brain interaction (DGBI) symptoms during the COVID-19 pandemic, and evaluated factors associated with symptom severity changes. METHODS: Electronic databases were searched until February 2024, for articles reporting on changes in symptom severity in DGBI patients during the COVID-19 pandemic. The proportion of DGBI patients who reported a change in their symptom severity were pooled using a random-effects model, and subgroup analyses were conducted to assess the effect of socio-cultural modifiers on symptom severity in DGBI. KEY RESULTS: Twelve studies including 3610 DGBI patients found that 31.4% (95% CI, 15.9-52.5) of DGBI patients experienced symptom deterioration, while 24.3% (95% CI, 10.2-47.5) experienced improvement. Countries with high gross domestic product (GDP) had a 43.5% (95% CI, 16.3-75.2) likelihood of symptom deterioration, compared to 9.2% (95% CI, 1.4-42.2) in lower GDP countries. Similarly, countries with low COVID fatality rates had a 60.1% (95% CI, 19.7-90.3) likelihood of symptom deterioration, compared to 18.3% (95% CI, 7.8-36.9) in higher fatality rate countries. Countries with lenient COVID policies had a 58.4% (95% CI, 14.1-92.3) likelihood of symptom deterioration, compared to 19% (95% CI, 8.2-38.1) in countries with stricter policies. Patients in high vaccine hesitancy countries had a 51.4% (95% CI, 19.5-82.2) likelihood of symptom deterioration, compared to 10.6% (95% CI, 2.7-33.4) in low vaccine hesitancy countries. CONCLUSIONS & INFERENCES: This meta-analysis reveals that a significantly higher proportion of DGBI patients experienced deterioration of symptoms during the COVID-19 pandemic. Various sociocultural, economic and environmental factors potentially modify the effects of the COVID-19 pandemic on DGBI.
RESUMO
BACKGROUND: Disorders of gut-brain interaction (DGBI) are characterized by debilitating symptoms not explained by structural or biochemical abnormalities. While functional conditions present with complex, likely heterogeneous pathophysiology, we aimed to investigate if proxy measures of sociocultural and environmental factors are associated with the prevalence of various DGBI in populations across the world. METHODS: We performed an ecological study utilizing peer-reviewed published datasets reporting for 26 countries prevalence rates of DGBI (Rome Foundation Global Epidemiology Study, RFGES), with six independent variables: Helicobacter pylori prevalence and household size as proxy measures for orofecal infections, gross domestic product per capita (GDP), and median age as a proxy measures for socioeconomic development, density of fast food outlets (FFO) per 100,000 population as proxy measure for processed food exposure, and suicide mortality rate per 100,000 people, and world happiness scores were used as a proxy for psychological stress. The data were retrieved from publicly accessible datasets (United Nations, CIA World Factbook, World Bank, World Happiness Report, commercial/financial reports of a global FFO chain). We used linear regression to assess variables in univariate and multivariate analysis and report standardized ß coefficients with 95% confidence intervals (CI). KEY RESULTS: The regression model revealed that the overall prevalence of DGBI was inversely associated with both GDP per capita (ß = -0.57, 95% CI: -0.92, -0.22, p = 0.002) and happiness scores (ß = -0.433 95% CI: 0.821, -0.065, p = 0.023), while being positively associated with H. pylori prevalence (ß = 0.40, 95% CI: 0.008, 0.81, p = 0.046). The prevalence of functional constipation (FC) was also inversely associated with GDP per capita (ß = -0.50, 95% CI: -0.86, -0.13, p = 0.01) and happiness scores (ß = -0.497, 95% CI: -0.863, -0.132, p = 0.01), while being positively associated with H. pylori prevalence (ß = 0.53, 95% CI: 0.16, 0.91, p = 0.007). The Multivariate model analysis revealed that combining the factors of H. pylori prevalence, suicide rate, household size and happiness scores showed statistically significant association with FC (p = 0.039). Household size (ß = -0.43, 95% CI: -0.82, 0.038, p = 0.033) and suicide rates (ß = 0.55, 95% CI: 0.19, 0.90, p = 0.004) were statistically significantly associated with functional diarrhea. Irritable bowel syndrome (IBS) was associated with GDP per capita (ß = -0.40, 95% CI: -0.79, -0.014, p = 0.043) and happiness scores (ß = -0.390, 95% CI: -0.778, -0.003, p = 0.049). CONCLUSIONS & INFERENCES: Utilizing publicly available data, the prevalence of DGBI across diverse countries is linked to various socio-cultural and environmental factors. Collectively, the data suggests that the prevalence of DGBI is increased in less prosperous regions of the world.

BACKGROUND: Functional dyspepsia-epigastric pain syndrome (FD-EPS) is characterized pathophysiologically by visceral hypersensitivity, but the effect of the temperature stimulation on gastric function has been seldom studied. AIM: The purpose of this study was to investigate the effects of liquid nutrients at different temperatures on the gastric accommodation, sensitivity, and gastric-wall compliance of healthy subjects (HS) and FD-EPS patients. METHODS: Ten FD-EPS patients (Roma III criteria) and ten HS were recruited into the study. Intragastric pressure (IGP) and gastric perfusion were measured and compared following the administration of liquid nutrients at 37 °C on day 1 and at 8 °C on day 2. RESULTS: Seven patients developed abdominal discomfort or abdominal pain after being given cold liquid nutrient. The administration of liquid nutrient at 8 °C resulted in an increase of IGP in HS (P=0.044), a significant decrease in gastric perfusion (P<0.0001), a marked increase in IGP (P=0.015), and a dramatic reduction in gastric wall compliance (P=0.012) in patients compared to the effects of liquid nutrient at 37 °C. In addition, IGP in patients was lower than that in HS at 37 °C liquid nutrient (P=0.036), and the gastric perfusion volume in patients at maximal satiety was also significantly reduced at 8 °C liquid nutrient compared with HS (P=0.017). CONCLUSIONS: Cold stimulation can increase the IGP in HS and FD-EPS patients, elevate the visceral sensitivity and reduce the gastric volume of FD-EPS patients. FD-EPS patients who are sensitive to cold may develop epigastric discomfort or pain.

BACKGROUND: Immune factors were involved in the pathophysiology of irritable bowel syndrome (IBS). The aim of the study was to test anti-neuronal antibodies in sera of IBS patients and demonstrate their correlations with IBS profiles and psychological disorders. METHODS: Patients with IBS met Rome III criteria and excluded organic diseases were enrolled. Controls included healthy subjects (HS), slow transit functional constipation, autoimmune diseases, and so on. Indirect immunofluorescence with monkey cerebellum and small intestine as substrates was used to detect anti-neuronal antibodies including anti-cerebral neuronal antibodies (ACNA) and anti-enteric neuronal antibodies (AENA). RESULTS: A total of 293 IBS patients, 100 HS and 153 disease controls were included in this study. The ACNA positive rate of IBS patients was significantly higher than HS (14% vs. 6%, p = 0.033). The positive rate of ACNA was significantly lower than AENA (14.0% vs. 76.8%, p = 0.028) in IBS patients. The prevalence of headache and sleeping disorder were higher in ACNA-positive IBS patients than ACNA-negative IBS patients (61% vs. 42.9%, p = 0.03; 75.6% vs. 57.1%, p = 0.03, respectively). Among IBS patients, ACNA and AENA were both negative in 21.8% patients, ACNA negative and AENA positive in 64.2% patients, and ACNA and AENA were both positive in 12.6% patients. There were no significant differences of intestinal symptoms among the three groups, while the prevalence of headache (64.9% vs. 37.5% and 44.7%, p = 0.03) and sleeping disorder (78.4% vs. 50.0% and 59.6%, p = 0.02) were higher in patients with both ACNA and AENA positive than patients with both ACNA and AENA negative, patients with ACNA negative and AENA positive. There were no significant differences of the prevalence of depression and anxiety, HAMD, and HAMA scores among the three groups. CONCLUSIONS AND INFERENCES: Anti-neuronal antibodies in sera of IBS patients were mainly targeted to enteric neurons and in a small part to cerebral neurons. ACNA were closely related to headache and sleeping disorder but unrelated to intestinal symptoms, depression, or anxiety of IBS patients.

BACKGROUND: In Asia, the proportion of patients with irritable bowel syndrome (IBS) with abdominal discomfort alone is significantly higher than that in western countries. The purposes of this study are to understand the cognition of abdominal pain and abdominal discomfort in Chinese patients with IBS and to compare the clinical characteristics of patients with abdominal pain alone and with abdominal discomfort alone. METHODS: Patients with IBS with diarrhea (IBS-D) who met the Rome III diagnostic criteria and had episodes of at least one day/week were consecutively enrolled. The cognition of abdominal pain and abdominal discomfort were investigated through face-to-face unstructured interview. Patients were divided into a pain group and a discomfort group according to the cognition interviews, then the characteristics and severity of symptoms (IBS symptom severity scale, IBS-SSS), IBS quality of life (IBS-QOL) and psychological state were compared between groups. RESULTS: A total of 88 patients with IBS-D were enrolled. Most of the patients with self-reported abdominal pain described their pain as spasm/cramping; patients with self-reported abdominal discomfort had as many as 24 different descriptions of discomfort. Most patients having abdominal pain and discomfort could accurately distinguish the two symptoms. The degree of abdominal pain in the pain group was higher than abdominal discomfort in the discomfort group (P = 0.002). There was no significant difference in IBS-SSS, extra-intestinal pain, IBS-QOL, and psychological state between the two groups. CONCLUSIONS: For Chinese patients with IBS-D, abdominal pain and abdominal discomfort are two different symptoms, but they have similar clinical features.

RESUMO
The occurrence of gastroesophageal reflux disease (GERD) and symptom onset are closely associated with diet. We aimed to compare the dietary and lifestyle triggers between non-erosive reflux disease (NERD) and reflux esophagitis (RE) in Chinese patients and to provide evidence for development of practical dietary modifications for GERD. A multicenter cross-sectional survey was conducted. A total of 396 GERD patients with typical gastroesophageal reflux symptoms who received upper endoscopy in the previous month were enrolled, including 203 cases of NERD patients and 193 cases of RE patients. All participants completed questionnaires including demographic data, reflux symptoms, previous management, dietary and lifestyle habits, triggers of reflux symptoms, psychological status, and quality of life. There were no significant differences in GERD symptom scores between NERD and RE. RE patients had a higher male proportion and smoking/drinking and overeating rates than NERD patients. In the NERD group, more patients reported that fruits, dairy products, yogurt, bean products, cold food, and carbonated beverages sometimes and often induced reflux symptoms and had more triggers compared to RE patients. The number of triggers was positively correlated to GERD symptom score and GERD-HRQL score in both NERD and RE patients. However, 74.0% of GERD patients still often consumed the triggering foods, even those foods that sometimes and often induced their reflux symptoms, which might be related to the reflux relapse after PPI withdrawal considering NERD and RE patients had similar GERD symptom severity. There were some differences in terms of dietary habits, dietary and lifestyle triggers, and related quality of life between NERD and RE, and these results may provide evidence of different approaches toward the dietary modification of NERD and RE patients.

OBJECTIVE: To explore the symptomatic features and psychosocial factors in patients with belching disorders. METHODS: At Peking Union Medical College Hospital Outpatient Clinic from September 2010 to January 2011, 21 consecutive patients with repetitive belching were profiled by symptom questionnaires, including general demographics, spectrum of symptoms, disease course, predisposing factors, previous treatment, psychosocial factors, mental status and personality traits, etc. Pearson's correlation analysis and exact probability were used. RESULTS: Among them, 20 patients fulfilled the Rome III criteria of belching disorders. There were 5 males and 15 females with an age range of (49 ± 10) years. Among them, the belching patterns were daily (n = 18), meal-related (n = 16), spontaneous (n = 15), controllable (n = 16) and symptomatic overlapping (n = 17). The most common symptoms were functional dyspepsia (FD) (n = 13) and gastroesophageal reflux disease (GERD) (n = 11). Sixteen patients experienced mental stimulation/negative events and 13 patients were related to family tension, work stress and overwork. There were 12 patients with anxiety and/or depression and 8 with neurotic personality. The number of overlapping symptoms was related to anxiety states (r = 0.47, t = 2.14, P < 0.05). But the severity of belching was unrelated to with or without depression and anxiety state (P = 0.096). CONCLUSIONS: There are a variety of clinical manifestations in patients with belching disorders. Belching disorders is often related to emotional change and environmental stress and accompanied by abnormal mental and personality characteristics. Belching may be an abnormal behavior reaction to gastrointestinal discomfort symptoms. The psychological and social factors probably play an important role in the pathogenesis of belching disorders.

OBJECTIVE: To survey the emotional and sleeping status of patients with chronic constipation (CC) and analyze the relationship between psychological status and constipated symptoms. METHODS: From January 2009 to April 2010, 5 centers and 25 stratified hospitals were selected as the representatives of different regions of mainland China. The CC questionnaires including constipated symptoms, emotional and sleeping status, previous treatments and self-reported impact of constipation on health status, etc. Questionnaires were completed by well-trained physicians or investigators during face-to-face interviews. CC was diagnosed in accordance with the Rome III criteria. RESULTS: A total of 909 valid questionnaires analyzed. There were 258 males and 651 females with a mean age of (49 ± 19) years. 41.5% (377 cases) reported "tense feelings" and 38.3% (348 cases) "felt downcast" over the past 3 months. The patients feeling tense and(or) downcast "frequently" and "most of time" were around 11.3% (103 cases) and 9.4% (85 cases). And 43.8% (398 cases) patients reported sleeping disorders over the past 3 months. Regional differences existed in the comorbidities of psychological and sleeping disorders in CC patients, especially in those from tertiary hospitals. And it was the highest in Beijing area for tense feelings and downcast. The sleeping disorders were the most common in the patients from secondary hospitals, of which 66.1% (37/56) and 65.0% (39/60) were from Wuhan and Xi'an respectively. They were higher than Beijing and Guangzhou (39.7% (23/58), 29.0% (9/31), all P = 0.001). The patients from rural primary clinics suffered more sleeping disorders than those from urban primary cares (P = 0.026). About 35.0% (318 cases) and 28.4% (258 cases) patients reported their constipation was related with emotional and sleeping disorders. The comorbidities of psychological and sleeping disorders were more common in severe constipated patients than mild and moderate counterparts and resulted in more hospital visits (both P = 0.000). CONCLUSIONS: The CC patients often have the comorbidities of psychological and sleeping disorders with regional differences. The patients from the hospitals at various levels may present different spectrums of comorbidities of psychological and sleeping disorders. And the severity of CC influences the moods, sleeps and hospital visits.

BACKGROUND: The Rome IV criteria eliminated abdominal discomfort for irritable bowel syndrome (IBS), which was previously included in Rome III. There are questions as to whether IBS patients with abdominal discomfort (seen in Rome III but not Rome IV) are different from those with abdominal pain (Rome IV). AIM: To compare bowel symptoms and psychosocial features in IBS patients diagnosed with Rome III criteria with abdominal discomfort, abdominal pain, and pain & discomfort. METHODS: We studied IBS patients meeting Rome III criteria. We administered the IBS symptom questionnaire, psychological status, and IBS quality of life. Patients were classified according to the predominant abdominal symptom associated with defecation into an only pain group, only discomfort group, and pain & discomfort group. We compared bowel symptoms, extraintestinal symptoms, IBS quality of life, psychological status and healthcare-seeking behaviors, and efficacy among the three groups. Finally, we tested risk factors for symptom reporting in IBS patients. RESULTS: Of the 367 Rome III IBS patients enrolled, 33.8% (124 cases) failed to meet Rome IV criteria for an IBS diagnosis. There were no meaningful differences between the pain group (n = 233) and the discomfort group (n = 83) for the following: (1) Frequency of defecatory abdominal pain or discomfort; (2) Bowel habits; (3) Coexisting extragastrointestinal pain; (4) Comorbid anxiety and depression; and (5) IBS quality of life scores except more patients in the discomfort group reported mild symptom than the pain group (22.9% vs 9.0%). There is a significant tendency for patients to report their defecatory and non-defecatory abdominal symptom as pain alone, or discomfort alone, or pain & discomfort (all P < 0.001). CONCLUSION: IBS patients with abdominal discomfort have similar bowel symptoms and psychosocial features to those with abdominal pain. IBS symptoms manifesting abdominal pain or discomfort may primarily be due to different sensation and reporting experience.

Immune activation and several autoantibodies might be involved in the pathophysiology of irritable bowel syndrome (IBS). We aimed to identify serum biomarkers for IBS by HuProt™ microarray. IBS patients met Rome III criteria were enrolled. Control groups included healthy controls (HCs) and disease controls (DCs). In stage I, we profiled sera from IBS and control groups with HuProt™ microarrays. Based on significant different proteins in stage I, IBS focused microarrays were constructed and validated in a larger cohort in stage II, then decision tree models were generated to establish a combination of biomarkers. In stage III, 4 purified proteins were verified by ELISA. Finally, we analyzed the correlation of autoantibodies with symptoms. In stage I, we identified 47 significant different proteins including 8 autoantibodies of IgG, 2 of IgA between IBS and HCs; 13 autoantibodies of IgG, 13 of IgA between IBS and DCs. In stage II, we found the positive rates of 14 IgG and IgA autoantibodies in IBS were significantly higher than HCs. Five autoantibodies of IgG and 7 IgA were comprehensively involved in differentiating IBS and HCs with the sensitivity and specificity to diagnose IBS as 40%-46.7% and 79.4%-86.3%. The median optical density value of ELAVL4 (IgG) and PIGP (IgA) were significantly higher in IBS than HCs. Parts of autoantibodies above were related to IBS symptoms. We found a combination of autoantibodies to differentiate IBS with HCs, but no specific autoantibodies could serve as serum biomarkers for IBS.
RESUMO
BACKGROUND: The quality of life in patients who develop low anterior resection syndrome (LARS) after surgery for mid-low rectal cancer is seriously impaired. The underlying pathophysiological mechanism of LARS has not been fully investigated. AIM: To assess anorectal function of mid-low rectal cancer patients developing LARS perioperatively. METHODS: Patients diagnosed with mid-low rectal cancer were included. The LARS score was used to evaluate defecation symptoms 3 and 6 mo after anterior resection or a stoma reversal procedure. Anorectal functions were assessed by three-dimensional high resolution anorectal manometry preoperatively and 3-6 mo after surgery. RESULTS: The study population consisted of 24 patients. The total LARS score was decreased at 6 mo compared with 3 mo after surgery (P < 0.05), but 58.3% (14/24) lasted as major LARS at 6 mo after surgery. The length of the high-pressure zone of the anal sphincter was significantly shorter, the mean resting pressure and maximal squeeze pressure of the anus were significantly lower than those before surgery in all patients (P < 0.05), especially in the neoadjuvant therapy group after surgery (n = 18). The focal pressure defects of the anal canal were detected in 70.8% of patients, and those patients had higher LARS scores at 3 mo postoperatively than those without focal pressure defects (P < 0.05). Spastic peristaltic contractions from the new rectum to anus were detected in 45.8% of patients, which were associated with a higher LARS score at 3 mo postoperatively (P < 0.05). CONCLUSION: The LARS score decreases over time after surgery in the majority of patients with mid-low rectal cancer. Anorectal dysfunctions, especially focal pressure defects of the anal canal and spastic peristaltic contractions from the new rectum to anus postoperatively, might be the major pathophysiological mechanisms of LARS.
