Abdominal Pain and Disturbed Bowel Movements are Frequent among Young People. A Population Based Study in Young Participants of the Woodstock Rock Festival in Poland

Impact of off-hour admission on the MACEs of patients with acute myocardial infarction

BACKGROUND

In China, on more than 100 weekends or holidays, only on-duty cardiologists are available during admissions. This study aimed to analyze the impact of admission time on major adverse cardiovascular events (MACEs) in patients with acute myocardial infarction (AMI).

METHODS

This prospective observational study enrolled patients with AMI between October 2018 and July 2019. The patients were assorted into off-hour (admitted on weekends or national holidays) and on-hour groups. The outcome was MACEs at admission and 1 year after discharge.

RESULTS

A total of 485 patients with AMI were enrolled in this study. The occurrence of MACEs was significantly higher in the off-hour group compared with the on-hour group (P < .05). Multivariate regression analysis showed that age (HR = 1.047, 95% CI: 1.021-1.073), blood glucose level (HR = 1.029, 95% CI: 1.009-1.050), multivessel disease (HR = 1.904, 95% CI: 1.074-3.375), and off-hour hospital admission (HR = 1.849, 95% CI: 1.125-3.039) were all independent risk factors for in-hospital MACEs, while percutaneous coronary intervention (HR = 0.210, 95% CI: 0.147-0.300) and on-hour admission (HR = 0.723, 95% CI: 0.532-0.984) were protective factors for MACEs 1 year after discharge.

CONCLUSION

The "off-hour effect" still existed in patients with AMI, and the risk of MACEs in the hospital and 1 year after discharge was higher for off-hour admission.

Functional abdominal pain disorders in children in southern Anhui Province, China are related to academic stress rather than academic performance

BACKGROUND

Functional abdominal pain disorders (FAPDs) are one of the most common gastrointestinal disorders in children. The aim of this study was to investigate the prevalence of FAPDs in children in southern Anhui Province, China and their association with academic stress.

METHODS

In this cross-sectional survey, we randomly selected children aged 6-17 years from 11 public schools in southern Anhui Province. FAPDs were diagnosed according to the Rome IV criteria, and a custom-designed questionnaire was used to investigate the association between academic stress and FAPDs in children.

RESULTS

A total of 2,344 children aged 6-17 years were enrolled. The mean age was 12.4 ± 3.0 years. Of these children, 335 (14.3%) were diagnosed with FAPDs according to the Rome IV criteria. Among the children with FAPDs, 156 (46.6%) were boys, and 179 (53.4%) were girls. The prevalence was higher in girls than in boys. The most common disorder was irritable bowel syndrome (IBS) (n = 182 (7.8%)). Other types of FAPDs included functional abdominal pain-not otherwise specified (FAPNOS) (n = 70 (3.0%)), functional dyspepsia (FD) (n = 55 (2.3%)), and abdominal migraine (AM) (n = 28 (1.2%)). Academic stress, not meeting parental expectations, poor relationships with parents, and sleep disturbances were independent risk factors for FAPDs in children; academic performance was not associated with the development of FAPDs.

CONCLUSION

There was a high prevalence of FAPDs among children in southern Anhui Province, China, and IBS was the most common subtype of functional abdominal pain. Academic stress, rather than academic performance, was associated with FAPDs in children.

Integrated fecal microbiome-metabolome signatures reflect stress and serotonin metabolism in irritable bowel syndrome

To gain insight into the complex microbiome-gut-brain axis in irritable bowel syndrome (IBS), several modalities of biological and clinical data must be combined. We aimed to identify profiles of fecal microbiota and metabolites associated with IBS and to delineate specific phenotypes of IBS that represent potential pathophysiological mechanisms. Fecal metabolites were measured using proton nuclear magnetic resonance (¹H-NMR) spectroscopy and gut microbiome using shotgun metagenomic sequencing (MGS) in a combined dataset of 142 IBS patients and 120 healthy controls (HCs) with extensive clinical, biological and phenotype information. Data were analyzed using support vector classification and regression and kernel t-SNE. Microbiome and metabolome profiles could distinguish IBS and HC with an area-under-the-receiver-operator-curve of 77.3% and 79.5%, respectively, but this could be improved by combining microbiota and metabolites to 83.6%. No significant differences in predictive ability of the microbiome-metabolome data were observed between the three classical, stool pattern-based, IBS subtypes. However, unsupervised clustering showed distinct subsets of IBS patients based on fecal microbiome-metabolome data. These clusters could be related plasma levels of serotonin and its metabolite 5-hydroxyindoleacetate, effects of psychological stress on gastrointestinal (GI) symptoms, onset of IBS after stressful events, medical history of previous abdominal surgery, dietary caloric intake and IBS symptom duration. Furthermore, pathways in metabolic reaction networks were integrated with microbiota data, that reflect the host-microbiome interactions in IBS. The identified microbiome-metabolome signatures for IBS, associated with altered serotonin metabolism and unfavorable stress response related to GI symptoms, support the microbiota-gut-brain link in the pathogenesis of IBS.

Irritable Bowel Syndrome Prevalence among Participants of Woodstock Rock Festival in Poland Based on Rome IV Criteria Questionnaire

BACKGROUND

Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder (FGID), in which etiology and pathogenesis are not fully explored. There is an ongoing need for more population studies adhering to new ROME IV criteria. In the current study, which follows our previous investigation among participants of the Woodstock Rock Festival in Poland, we aimed to evaluate the prevalence of IBS and its relation to age, gender, education, and IBS type.

METHODS

Rome IV criteria questionnaire was used to assess abdominal complaints of 386 participants of the Woodstock Rock festival 2018.

RESULTS

Analyzed data revealed that Rome IV criteria were met by 42 participants (11.41%), 11 men and 31 women (p = 0.0028), with following types of IBS: IBS-M (mixed form) 55%, IBS-D (with diarrhea) 33%, IBS-U (unclassified) 10%, IBS-C (with constipation) 2%. No statistically significant correlation between IBS prevalence and age, gender, or education (p > 0.05) was found.

CONCLUSIONS

The prevalence of IBS among major rock festival participants in Poland was high. Women met the criteria more often than men, which is consistent with global epidemiology for many years. Among participants of the Woodstock Rock Festival, the most frequent subtype was IBS-M, the rarest-IBS-C. There is a need of conducting cohort studies in bigger groups in our population.

Abdominal Pain in Young Adults

Aim. A study of abdominal pain incidence in young adults in relation to dietary habits and psychological profile for advancement of health-promoting technologies.

Materials and methods. An anonymous quiz survey covered 3,634 students enrolled at Omsk State Medical University in higher and secondary vocational education programmes via online use of the GSRS and WHO CINDI programme questionnaires to assess eating patterns and dietary preferences, as well as a brief multifactor personality inventory scale. Respondents with abdominal pain were divided into subcohorts by pain severity according to GSRS scores (mild, moderate or severe pain).

Results. Abdominal pain was reported by 2,300 (63.29%) respondents, of whom 1,243 (54.0%) rated symptoms as mild, 996 (43.3%) and 61 (2.7%) — as moderate to severe. Abdominal pain complaints were more frequent in women (2I = 33.96, p <0.001), but gender had no effect on pain intensity. Pain associated with abdominal bloating and distention (57.65%), gastroesophageal reflux symptoms (38.75%), constipation (30.54%) or diarrhoea (28.4%). The presence and severity of abdominal pain was distinctive of individuals spending the most of average monthly income on food purchase and those actively consuming tea, coffee, added sugar, extra salt in cooked food, while having low intake of fruit and vegetables. A typical personality in severe abdominal pain is hypothymic depressive, hypochondriac in moderate and psychasthenic in mild pain.

Conclusion. Abdominal pain is common among medical students predominating in females, associates with the eating pattern, dietary habits and psychological profile.

'Dr. Google, I have a stomach ache' - seasonal variations in abdominal pain: a 4-year retrospective data analysis from Google Ads keywords planner

BACKGROUND

Internet traffic may reflect the prevalence of real-world ailments. The aim of this study was to analyse queries associated with abdominal pain and to investigate seasonal frequency and trends of searches in Poland.

METHODS

We analysed mean search volume from March 2015 to February 2019 of keywords associated with 'abdominal pain' in the Polish language generated from the Google Ads Planner. Keywords were categorised by location, feature or type of pain, concurrent symptoms, frequency and patient groups, etc. We compared differences in search volumes across seasons and years.

RESULTS

Overall, 24,673,430 queries were associated with abdominal pain in the period analysed. The number of searches associated with abdominal pain in winter increased by ~30% compared with queries searched in summer. There were significantly more searches related to abdominal pain located in the epigastric, umbilical, hypogastrium, left lumbar, left iliac and right iliac regions combined with vomiting or fever, and acute or burning sensation in cold months. We did not observe any specific patterns of pain in the right lumbar or left hypochondrium region, co-presence of flatulence, acute, cramping or persistent/chronic or strong abdominal pain.

CONCLUSION

Internet queries associated with abdominal pain and related factors have increased in the past 4 years and present a seasonal pattern. Google Ads may be a valuable tool to assess the prevalence of complaints in under-researched regions. The observed trends in queries related to abdominal pain merely reflect the scale of the problem. The reported pattern should be verified in epidemiological studies.

Analysis of Answers to Queries among Anonymous Users with Gastroenterological Problems on an Internet Forum

Internet forums are an attractive source of health-related information. We aimed to investigate threads in the gastroenterological section of a popular Polish medical forum for anonymous users. We characterised the following aspects in threads: the main problem of the original poster, declared ailments and rationale of the responses (rational, neutral, harmful or not related to the problem of the original poster). We analysed over 2717 forum threads initiated in the years 2010–2018. Users mostly asked for diagnosis of the problem [1814 (66.8%)], treatment [1056 (38.9%)] and diagnostic interpretation [308 (11.3%)]. The most commonly declared symptoms were abdominal pain [1046 (38.5%)], diarrhea [454 (16.7%)] and bloating [354 (13.0%)]. Alarm symptoms were mentioned in 309 (11.4%) threads. From the total 3550 responses, 1257 (35.4%) were assessed as rational, 693 (19.5%) as neutral, 157 (4.4%) as harmful and 1440 (40.6%) as not related to the user’s problem. The original poster’s declaration of blood in stool, dyspepsia, pain in the abdominal right lower quadrant, weight loss or inflammatory bowel disease was positively related to obtaining at least one potentially harmful response. Advice from anonymous users on Internet forums may be irrational and disregards alarm symptoms, which can delay the diagnosis of life-threatening diseases.

Are probiotics useful in the treatment of chronic idiopathic constipation in adults? A review of existing systematic reviews, meta-analyses, and recommendations

Chronic idiopathic constipation (CIC) has emerged as common problem for contemporary gastroenterology and is one of the most frequent complaints in primary care. Chronic idiopathic constipation significantly affects patients' quality of life and has an impact on global health and economy. Functional gastrointestinal disorders and bowel disorders, according to Rome IV criteria, result from inappropriate gut-brain interactions. The pathophysiology is complex and poorly understood, with evidence accumulating that gut microbiota can be implicated in the development and function of the enteric nervous system. Gut bacteria modulate gut barrier function, short chain fatty acid synthesis, and bile acid metabolism, factors which play roles in the gut peristalsis regulation. The high prevalence of CIC, with poor treatment outcomes, warrants searches for new forms of therapy, including probiotic therapies. Probiotics are often recommended by medical practitioners, but evidence-based utility in adults with CIC is uncertain. Recommendations/guidelines are often based on results from individual studies, rather than meta-analyses or umbrella reviews. Additionally, meta-analyses often indicate a group of probiotics rather than individual strains, and they create difficulty for physicians in making therapeutic choices. More CIC patient randomised clinical studies utilising well-defined strains, or combinations, are necessary.
