Self-Reported Gastrointestinal Symptoms Associated with NSAIDs and Caffeine Consumption in a Jordanian Subpopulation. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1519. [PMID: 39336561 PMCID: PMC11433810 DOI: 10.3390/medicina60091519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2024] [Revised: 09/14/2024] [Accepted: 09/16/2024] [Indexed: 09/30/2024]
Abstract
Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) and caffeine-containing beverages are widely consumed but their impact on gastrointestinal (GI) health requires further investigation. This cross-sectional study investigated the relationship between NSAIDs use, caffeinated drink consumption, and the prevalence of self-reported GI symptoms in a Jordanian subpopulation. Methods: An online survey was administered to 400 Jordanian individuals aged 18-65 years. Data on sociodemographics, NSAIDs use, caffeine consumption, peptic ulcer disease (PUD) history, and GI symptoms were collected. Contingency tables were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between exposures and outcomes. Results: The prevalence of self-reported PUD-related GI symptoms was 6.0%. NSAID users had higher odds of PUD (OR = 2.431) and related GI symptoms, including abdominal pain (OR = 4.688, p < 0.001) and discomfort (OR = 8.068, p < 0.001). Caffeine consumption was associated with self-reported burning stomach pain (OR = 14.104, p < 0.001), fullness (OR = 8.304, p = 0.010), and bloating (OR = 8.304, p = 0.010). Coffee, tea, soft drinks, and energy drinks were associated with increased odds of various GI symptoms (ORs 2.018-12.715, p < 0.05). Conclusions: NSAIDs use and caffeine consumption were independently associated with the increased prevalence of self-reported PUD and related GI symptoms. Despite the lack of adjustment for necessary confounders, our findings highlight the importance of considering the potential GI effects of NSAIDs and caffeine. Public health strategies promoting their safe use may help reduce the burden of GI disorders.

Neurogastroenterol Motil 2024:e14898. [PMID: 39119757 DOI: 10.1111/nmo.14898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 07/17/2024] [Accepted: 07/31/2024] [Indexed: 08/10/2024]
Abstract
BACKGROUND Unsupervised machine learning describes a collection of powerful techniques that seek to identify hidden patterns in unlabeled data. These techniques can be broadly categorized into dimension reduction, which transforms and combines the original set of measurements to simplify data, and cluster analysis, which seeks to group subjects based on some measure of similarity. Unsupervised machine learning can be used to explore alternative subtyping of disorders of gut-brain interaction (DGBI) compared to the existing gastrointestinal symptom-based definitions of Rome IV. PURPOSE This present review aims to familiarize the reader with fundamental concepts of unsupervised machine learning using accessible definitions and provide a critical summary of their application to the evaluation of DGBI subtyping. By considering the overlap between Rome IV clinical definitions and identified clusters, along with clinical and physiological insights, this paper speculates on the possible implications for DGBI. Also considered are algorithmic developments in the unsupervised machine learning community that may help leverage increasingly available omics data to explore biologically informed definitions. Unsupervised machine learning challenges the modern subtyping of DGBI and, with the necessary clinical validation, has the potential to enhance future iterations of the Rome criteria to identify more homogeneous, diagnosable, and treatable patient populations.

Abstract
OBJECTIVE This study examined the impact of State and Trait anxiety and dietary intake on college students' gastrointestinal symptoms during the COVID-19 pandemic. PARTICIPANTS A total of 455 students, aged 18-23, from two residential colleges in the midwestern United States participated in the study during April 2021. METHODS An online questionnaire that included the National Cancer Institute Dietary Screener, State-Trait Inventory for Cognitive and Somatic Anxiety, and an adapted version of the Gastrointestinal Symptoms Questionnaire was used. Stepwise multiple regression analyses and Spearman rho correlation coefficients were used to analyze the data. RESULTS High rates of State-somatic, State-cognitive, and Trait-somatic anxiety were present in our study population. These anxiety subscales and dietary intake predicted 26% and 3.8% of the GI symptoms variance, respectively. CONCLUSION State-anxiety and Trait-somatic anxiety are large factors in predicting GI symptoms compared to dietary intake. College students could seek anxiety-reducing techniques to ease GI symptoms.

Abstract
OBJECTIVE To develop and validate a set of static and animated gastroduodenal symptom pictograms for children. STUDY DESIGN There were 3 study phases: 1: cocreation using experience design methods to develop pediatric gastroduodenal symptom pictograms (static and animated); 2: an online survey to assess acceptability, as well as face and content validity; and 3: a preference study. Phases 2 and 3 compared the novel pediatric pictograms with existing pictograms used with adult patients. RESULTS Eight children aged 6-15 years (5 female) participated in phase 1, and 69 children in phase 2 (median age 13 years: IQR 9-15); an additional 49 participants were included in phase 3 (median age 15: IQR 12-17). Face and content validity were higher for the pediatric static and animated pictogram sets compared with pre-existing adult pictograms (78% vs 78% vs 61%). Participants with worse gastric symptoms had superior comprehension of the pediatric pictograms (χ2 [8, N = 118] P < .001). All participants preferred the pediatric static pictogram set was over both the animated and adult sets (χ2 [2, N = 118] P < .001). CONCLUSIONS The cocreation phase resulted in the symptom concept confirmation and design of 10 acceptable static and animated gastroduodenal pictograms with high face and content validity when evaluated with children aged 6-18. Validity was superior when children reported more problematic symptoms. Therefore, these pictograms could be used in clinical and research practice to enable standardized symptom reporting for children with gastroduodenal disorders.

Abstract
BACKGROUND Evidence on the effects of bovine colostrum (BC) supplementation on gastrointestinal (GI) diseases is conflicting. OBJECTIVES This systematic review summarized the findings of clinical trials (CTs) on the effects of BC supplementation on GI diseases. METHODS A systematic search was conducted in online databases, including PubMed, ISI Web of Science, and Scopus, until March 2021 and updated until December 2023. CTs investigated BC's effect on any measurable symptomatic change in terms of GI health as the primary outcome variable or as one of the outcomes in any population eligible for this systematic review. RESULTS Out of 6881 records, 22 CTs (uncontrolled = 4, cross-over = 1, and parallel = 17) with 1427 patients were enrolled in the systematic review. Diarrhea, the most frequently evaluated symptom (20 interventional arms), was decreased in frequency with BC supplementation in 15 of these arms. However, most studies reported no change in its duration. BC supplementation consistently reduced stool frequency across all seven studies. Abdominal pain relief was noted in four interventional arms but showed no improvement in five others. Assessment of other GI symptoms was limited, yielding inconclusive results. CONCLUSIONS There is limited evidence on the effects of BC on GI diseases, with mixed findings. More well-designed controlled clinical trials are required to explore its effects.

Abstract
BACKGROUND Women experience more severe gastrointestinal (GI) symptoms compared to men. The onset of puberty and the menstrual cycle may influence these differences. Additionally, health anxiety is an important construct that has been shown to play a role in increased symptomatology across many medical conditions. Using standardized clinical measures often employed to assess disorders of gut-brain interaction (DGBI) we aimed to identify differences of GI functioning across menstrual cycle phases and to evaluate the role of health anxiety in this relationship. METHODS Six hundred three participants completed a survey including functional GI assessment scales (PROMIS-GI®), an abdominal pain scale and map, and a health anxiety measure. They were grouped by menstrual cycle phases (Menses, Follicular, Early-Luteal, and Premenstrual) based on self-reported start date of most recent period. Multivariate analyses of covariance were conducted to identify differences between menstrual cycle phase and scores on the symptom scales. Heath anxiety was included as a covariate in all analyses. RESULTS No significant differences were found between menstrual cycle group and PROMIS-GI scores. Higher GI-symptom and pain levels were found as health anxiety increased. Pain in the hypogastric region of the abdomen was significantly higher during the Menses phase when compared to Early-Luteal and Premenstrual phases. A subset of participants with DGBI diagnoses demonstrated significantly higher GI-symptom severity on several PROMIS-GI scales when compared to matched controls who did not have those diagnoses. In addition, participants with DGBI diagnoses reported significantly greater pain across multiple abdominal regions than their non-diagnosed counterparts. CONCLUSIONS GI symptom levels as measured by the PROMIS-GI scales in otherwise healthy women were not dependent on menstrual cycle phase. Yet, the PROMIS-GI scales were sensitive to symptom differences in women with DGBI diagnoses. Overall, this study demonstrated that the PROMIS-GI measures are unlikely to be affected by gynecological functioning in healthy young women. We argue that the abdominal pain map is an essential addition to classification and diagnosis.

Abstract
There is a growing awareness that supplementation with probiotic bacteria can impart beneficial effects during gastrointestinal disease, but less is known about the impact of probiotics on healthy subjects. Here, we report the outcomes of a post hoc analysis of recorded daily gastrointestinal events and bowel habits completed by healthy adults participating in a placebo-controlled, single-centre, randomised, double-blind, quadruple-arm probiotic tolerability study. Extensive screening ensured the healthy status of subjects entering the study and during a 2-week pre-intervention run-in period, a burden of gastrointestinal events (stomach pains, indigestion, acid reflux, stomach tightening, nausea and vomiting, stomach rumbling, bloating, belching and flatulence) was identified suggesting GI discomfort within the population. In the subsequent 12-week intervention period with 3 distinct probiotic formulations and a matched-placebo, reductions in the incidence rates of bloating, borborygmus, stomach pains, slow faecal transit and incomplete defecations were observed in the probiotic groups compared to the placebo. These results highlighted differing responses among the probiotic formulations tested and indicated potential anti-constipation effects. Product specific modulations in circulating interleukin-6 levels and in the composition of the gut microbiota were also detected. Together, these data suggest a role for probiotic supplementation to exert beneficial effects on the gastrointestinal functioning of healthy subjects and highlight the need for further longer-term studies in healthy populations to gain a greater understanding of the impact of probiotics.

Abstract
This study evaluated the association between dietary patterns, Gas-Related Symptoms (GRS) and their impact on quality of life (QoL) in a representative sample (n=936) of the French adult population. During the 2018-2019 "Comportements et Consommations Alimentaires en France" (CCAF) survey (Behaviors and Food Consumption in France), online evaluation of GRS in adult participants was performed using the validated Intestinal Gas Questionnaire (IGQ), which captures the perception of GRS and their impact on QoL via 6 symptom dimensions scores (range 0-100; 100=worse) and a global score (mean of the sum of the 6 symptom dimensions scores). Socio-demographics, lifestyle parameters and dietary habits (7-day e-food diary) were also collected online. Quality of diet was determined using the NRF9.3 score (range 0-900; 900=best). Univariate and multivariate linear regression models were applied to identify factors associated with IGQ global score. K-means was used to identify clusters of subjects based on their dietary records. Data from 936 adults who completed both the IGQ and the food diary showed a mean (SD) IGQ global score of 11.9 (11.2). Younger age and female gender were associated with a higher IGQ global score. Only 7% of subjects reported no symptom at all and nearly 30% of study participants reported a high impact of GRS on their QoL. Two dietary clusters were identified: cluster1, characterized by a higher consumption of fruits and vegetables, lower sugars intake and higher NRF9.3 score and cluster 2, characterized by higher intake of sugars, lower intake in dietary fibers and lower NRF9.3 score. The IGQ global score was lower in cluster1 and higher in cluster2 vs. the total sample average (p<0.001). Prevalence of GRS in the French adult population is high and is associated with impaired QoL and dietary patterns. A change in food habits towards healthier patterns could help reducing the burden of GRS.

Abstract
Background Few health-related quality of life (QOL) questionnaires are designed specifically for healthy populations and are specific to gastrointestinal (GI) symptoms even though healthy individuals may frequently experience gas, bloating, constipation, diarrhea, and abdominal pain. The purpose of this study was to develop and validate a tool that could assess the impact of GI symptoms on digestion-associated QOL in otherwise healthy individuals. Methods After a review of current literature and with input from experienced GI researchers, a 24-item questionnaire was created. The questionnaire was reduced to 9 items with input from focus groups comprised of healthy adults experiencing GI-related symptoms and through variability analysis. The Digestion-associated QOL Questionnaire (DQLQ) was designed to be sensitive to the physical and mental well-being changes that may occur due to GI symptoms. The DQLQ was assessed for internal consistency reliability (Cronbach’s alpha; McDonald’s omega), test–retest reliability (intraclass correlation coefficient, ICC), and construct validity (Pearson correlations) in a study with healthy, academically stressed, undergraduate students. Convergent validity was evaluated by correlating the DQLQ with gastrointestinal symptom rating scale (GSRS) scores. Divergent validity was assessed by correlating DQLQ scores with stress scores, and bowel satisfaction scores. Results A total of 594 students (age 18–30 years) completed the DQLQ. Internal consistency reliability was favorable (n = 594; α = 0.84, ω = 0.84). A high level of agreement and correlation between DQLQ scores was found with the test–retest reliability analysis (n = 273; ICC = 0.89). The questionnaire was shown to have good convergent validity through correlation with the GSRS (n = 594; r = 0.54). Divergent validity was also shown to be appropriate by correlating DQLQ scores with stress (n = 592; r = 0.13, p < 0.005), and bowel satisfaction (n = 592; r = 0.18, p < 0.001) scores. Conclusion The DQLQ is a reliable and valid questionnaire for assessing digestion-associated QOL in healthy individuals.
