Our study aimed to elucidate the relationships among intestinal microhemodynamics, genetic background, sex, and microbial composition.MethodsTo dissect the microhemodynamic landscape of the BALB/c, C57BL/6J, and KM mouse strains, laser Doppler flowmetry paired with wavelet transform analysis was utilized to determine the amplitude of characteristic oscillatory patterns. Microbial consortia were profiled using 16S rRNA gene sequencing. To augment our investigation, a broad-spectrum antibiotic regimen was administered to these strains to evaluate the impact of gut microbiota depletion on intestinal microhemodynamics. Immunohistochemical analyses were used to quantify platelet endothelial cell adhesion molecule-1 (PECAM-1), estrogen receptor α (ESR1), and estrogen receptor β (ESR2) expression.ResultsOur findings revealed strain-dependent and sex-related disparities in microhemodynamic profiles and characteristic oscillatory behaviors. Significant differences in the gut microbiota contingent upon sex and genetic lineage were observed, with correlational analyses indicating an influence of the microbiota on microhemodynamic parameters. Following antibiotic treatment, distinct changes in blood perfusion levels and velocities were observed, including a reduction in female C57BL/6J mice and a general decrease in perfusion velocity. Enhanced erythrocyte aggregation and modulated endothelial function post-antibiotic treatment indicated that a systemic response to microbiota depletion impacted cardiac amplitude. Immunohistochemical data revealed strain-specific and sex-specific PECAM-1 and ESR1 expression patterns that aligned with observed intestinal microhemodynamic changes.ConclusionsThis study highlights the influence of both genetic and sex-specific factors on intestinal microhemodynamics and the gut microbiota in mice. These findings also emphasize a substantial correlation between intestinal microhemodynamics and the compositional dynamics of the gut bacterial community.","PeriodicalId":54275,"journal":{"name":"Gastroenterology Report","volume":"201 1","pages":"goae087"},"PeriodicalIF":3.6,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the present study was to investigate the frequency rate of HH among patients who underwent esophagogastroduodenoscopy (EGD) according to their age, gender, and procedural indication. Methods A multicenter, retrospective study including all EGDs was conducted across seven endoscopy departments between 2016 and 2021. Demographic information, procedural indications, and findings from the initial EGD were collected. Results Of the 162,608 EGDs examined, 96,369 (59.3%) involved female patients. HH was identified in 39,619 (24.4%) of all EGDs performed, comprising small HH in 31,562 (79.6%) and large HH in 3,547 (9.0%). The frequency of HH was 16.5% in the age group of ≤50 years and 37.3% in those aged ≥81 years. HH was diagnosed in 38.7% (11,370) of patients with heartburn/reflux symptoms, 31.5% of those with dysphagia, 28.5% of those with positive fecal occult blood tests, and 24.3% of those who would undergo bariatric surgery. Age (odds ratio 1.030), female gender (odds ratio 1.309), reflux symptoms (odds ratio 2.314), and dysphagia (odds ratio 1.470) were identified as predictors for HH. Conclusions Risk factors for HH diagnosed by EGD in symptomatic patients were shown to be advanced age, female gender, and the presence of heartburn or dysphagia.","PeriodicalId":54275,"journal":{"name":"Gastroenterology Report","volume":"13 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classically, endoscopic ultrasound (EUS) was used to assess the portal venous system and collaterals, considering size and hemodynamic parameters, which correlate with portal hypertension (PH) and related complications. Furthermore, therapeutic EUS guides treatment interventions, such as embolization of the gastric varices through coil placement and tissue adhesive injection, yielding encouraging clinical results. Recently, the direct measurement of portal pressure, emerging as an alternative to hepatic venous pressure gradient, has shown promise, and further research in this area is anticipated. In this review, we aimed to provide a detailed description of various possibilities for diagnosing vascular anatomy and hemodynamics in PH and actual knowledge on the EUS usefulness for PH vessel-related complications.

However, there is little direct evidence regarding its application in gastric cancer surgery. We aimed to evaluate the gastric residual volume, safety, and effectiveness of drinking 250 mL of 5% glucose solution 2-3 hours before elective gastric cancer surgery.MethodsWe conducted an investigator-initiated, multicenter, randomized-controlled, parallel group, and equivalence trial. Eighty-eight patients with gastric adenocarcinoma were randomized into study or control group. Patients in the control group followed the traditional routine of 6-8 hours preoperative fasting, while those in the study group drank 250 mL of 5% glucose solution 2-3 hours before surgery. Immediately following tracheal intubation, gastric contents were aspirated through gastroscopy. The primary outcome was preoperative gastric residual volume.ResultsEighty-three patients were eventually analysed in the study (42 in the study group and 41 in the control group). Two groups were comparable at baseline characteristics. There were no statistical differences in residual gastric fluid volumes (35.86 ± 27.13 vs 27.70 ± 20.37 mL, P = 0.135) and pH values (2.81 ± 1.99 vs 2.66 ± 1.68, P = 0.708) between the two groups. Preoperative discomfort was significantly more decreased in the study group than in the control group (thirst score: 1.49 ± 1.23 vs 4.14 ± 2.07, P < 0.001; hunger score: 1.66 ± 1.18 vs 3.00 ± 2.32, P = 0.007). There was no statistical difference in the incidence of postoperative complications (19.05% vs 17.07%, P = 0.815).ConclusionsDrinking 250 mL of 5% glucose solution 2-3 hours before surgery in elective gastric cancer patients shows benefits in lowering thirst and hunger scores without increasing gastric residual volume and perioperative complications.","PeriodicalId":54275,"journal":{"name":"Gastroenterology Report","volume":"63 1","pages":"goae077"},"PeriodicalIF":3.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Murine studies have indicated that several oral microbes exacerbate intestinal inflammation.
