This review will focus on the role of cysteine as a coin that mediates the metabolic crosstalk between microbiota and cancer. The key points enclose the way cysteine can be made available by the microbiota, by degradation of more complex compounds or by de novo synthesis, in order to contribute to the enrichment of the colonic microenvironment as well to the increase of cysteine systemic bioavailability. In addition, the main metabolic pathways in cancer that rely on cysteine as a source of energy and biomass will be pointed out and how the interspecific relationship with the microbiota and its dynamics related to aging may be relevant points to explore, contributing to a better understanding of cancer biology.","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49313330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods This was a retrospective study based on real-world data, which were collected from the Ningbo First Hospital in China from December 2019 to October 2020. Outpatients included were classified into the digestive and the non-digestive physician groups according to the referring physician. The primary outcome was adequate bowel preparation measured by the Boston Bowel Preparation Scale (BBPS), namely, a BBPS score of 2 or higher in any colonic segment and a total score ≥ 6. Secondary outcomes included the total mean BBPS scores and possible risk factors associated with poor bowel preparation. Results There were 671 outpatients included, with 392 in the digestive physician group and 279 in the non-digestive physician group. Adequate bowel preparation was 84.2% in the digestive physician group and 71.0% in the non-digestive physician group (odds ratio [OR]: 1.50, p < 0.001), and the latter had lower total mean BBPS scores (6.12 ± 1.33 vs. 6.66 ± 1.29, p < 0.001). The non-digestive physician was an independent risk factor according to the multivariate logistic regression analysis (OR: 0.45, p < 0.001).

Nevertheless, there is no data available on the magnitude of occult hepatitis among blood donors in Ethiopia. Therefore, this study aimed to estimate the magnitude of OBI among blood donors in Ethiopia. Objectives The aim of this study is to determine the magnitude of OBI and associated risk factors among blood donors at the National Blood Bank, Addis Ababa, Ethiopia. Methods A total of 973 HBsAg-negative plasma samples were tested for anti-HBc antibody using an ELISA and viral DNA using automated ABBOTT real-time PCR. Along with plasma samples, demographic data were retrieved from the database with respect to donors. Both descriptive and inferential statistics were employed for the analysis of data by SPSS 20. p-values less than 0.05 were considered as statistically significant. Results Of the total of 973 study participants, 445 (45.7%) were female with a mean age of 26.5 years. A total of 144 (14.8%) blood samples were anti-HBc antibody reactive. Four (0.41% of all samples, and 2.8% of anti-HBc-positive samples) samples were confirmed to have OBI by DNA detection. The mean viral load among the confirmed OBI samples was 31 IU/ml with ±12 SD, suggesting true occult hepatitis BV infections. Age was found to be a risk factor for anti-core positivity and was statically significant at p = 0.0001. Conclusion About four out of 1,000 blood donors screened negative with HBsAg had occult HBV infection. This shows that there could be a risk of HBV transmission through blood transfusion in Ethiopia. Therefore, there is a need for further investigation and action to revise the existing blood screening strategy by including anti-HBc and HBV nucleic acid testing.","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48438894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective This exploratory analysis of the palliative arm of the SORAMIC trial (ClinicalTrials.gov NCT01126645) evaluated the prognostic potential of basal and dynamic changes in systemic levels of interleukin 6 (IL-6), interleukin 8 (IL-8), systemic vascular endothelial growth factor (VEGF), and lipopolysaccharide (LPS). Methods We evaluated the correlations between overall survival (OS) and concentrations of IL-6, IL-8, VEGF, and LPS at follow-up approximately 7-9 weeks after treatment initialization (FU) compared to baseline (BL) in 90 patients treated either with 90Yttrium (90Y) microspheres combined with sorafenib (n = 44) or with sorafenib (n = 46) alone. Results Changes in IL-6 concentration during treatment showed correlations with the outcome. An increase in IL-6 concentration of less than 16.8 pg/mL over baseline readings was associated with better survival [median OS 16.3 months compared with 8.9 months (p = 0.0354)]. Correlations with survival were not observed for VEGF or LPS concentrations at baseline, at FU, or changes between these time points.

However, the method of CRC screening varies among countries. Primary colonoscopy screening is the most effective screening option from an individual point of view, but it is costly and population-wide participation rates are relatively low. Repeated screening with a fecal immunochemical test (FIT) is a non-invasive and inexpensive way to select individuals at high risk for CRC for colonoscopy. Despite its widespread use and mostly high participation rates, FIT is not perfect. Its sensitivity for advanced neoplasia (AN) is low. Besides, the false positivity rate of FIT is relatively high. This leads to unnecessary colonoscopies, anxiety, and risks among FIT-positives. New strategies need to be developed to improve CRC screening. In the past years, much research has been undertaken on risk-based screening or risk models. These include tests consisting of multiple risk factors and/or biomarkers that either assess the risk of disease at a single point in time (cross-sectional risk models) or predict the risk of developing CRC in the future (longitudinal risk models). We provide an overview of the developments on risk models for CRC screening and discuss some of the obstacles that need to be overcome to enable widespread implementation in existing CRC screening programs.","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44584148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the risk of lymph node metastases is only 1-2% when excluding risk factors for metastases other than depth of submucosal invasion. The number of elderly patients with significant comorbidities is increasing with societal aging in Japan. Therefore, local endoscopic resection of T1b colorectal cancers needs more consideration in the future. We previously showed that the pocket-creation method (PCM) for endoscopic submucosal dissection (ESD) is useful regardless of the morphology, including large sessile tumors with submucosal fibrosis, or location of the colorectal tumor. However, some T1b colorectal cancers have pathologically positive margins even when using the PCM. We retrospectively investigated the causes of failure to achieve negative vertical margins. Methods We retrospectively analyzed 953 colorectal tumors in 886 patients resected with the PCM. Finally, 65 pathological T1b colorectal cancers after en bloc resection were included in this study. ESD specimens and recorded procedure videos of T1b cancer resections with pathologically positive vertical margins were reviewed. Results The 65 cancers were divided into positive vertical margin (VM+ group) and negative vertical margin (VM- group) groups with 10 [10/65 (15%)] and 55 [55/65 (85%)] patients in each group, respectively. There was a significant difference in the rate of submucosal fibrosis (P=0.012) and dissection speed (P=0.044). There were no significant differences between the two groups in other regards. When verifying 8/10 available videos in the VM+ group, endoscopic technical factors led to positive vertical margins in five patients, and essential pathological factors of ESD led to positive vertical margins in the other three. Six of these eight patients underwent additional surgical resection. No residual tumor was identified in six T1b cancers. None of these six resected specimens contained lymph node metastases on pathological examination. Conclusion The PCM resulted in a high rate of negative-vertical-margin resections. The PCM resulted in complete resection of T1b cancers when examining additional surgical specimens. ESD using the PCM is a viable option for the endoscopic treatment of T1b colorectal cancers.","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44686866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the evolution of myocardial contractility assessed by speckle tracking echocardiography (STE) after transjugular intrahepatic portosystemic shunt (TIPS) placement and its prognostic value in outcome. Methods In this study, 206 (126 males) patients with liver cirrhosis receiving TIPS were included. In all study patients, conventional transthoracic echocardiography (TTE) was performed before and in the first weeks after TIPS placement to assess left and right ventricular volume, planar and functional parameters. Also, LV-GLS was measured by STE to assess left ventricular contractility as surrogate for myocardial dysfunction. Hemodynamic and clinical parameters were assessed before TIPS and during follow-up. Results As expected, most conventional parameters of TTE showed a significant change after TIPS placement. However, neither the absolute values, nor the changes of conventional cardiac parameters of TTE before and after TIPS insertion were associated with survival. By contrast, an increase in contractility of more than 20% using STE after TIPS was an independent predictor of mortality. Conclusion These results demonstrate that an increase of left ventricular contractility of more than 20% after TIPS insertion is an independent predictor of survival and this may identify patients at risk and in need of closer follow-up care.","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41558629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taenia asiatica, Taenia saginata, and Taenia solium are the most common pathogens causing human taeniasis. Among the three species of tapeworms, T. saginata and T. asiatica share high similarity in their genomes and have been reported to be capable of hybridization with each other. Here, we reported a case of an 18-year-old male patient hospitalized in Yunnan Province, China, in 2019. Due to long-lasting abdominal distension and white tapeworm segments in the feces, the patient was diagnosed with taeniasis. He was treated with traditional Chinese medicine, and a tapeworm approximately 2.7 m long was expelled. The morphology of the eggs and gravid proglottids of the tapeworm was observed. Interestingly, the tapeworm was identified as a hybrid between T. saginata and T. asiatica according to molecular and phylogenetic analyses. This case is the first documented case of human taeniasis caused by a T. saginata and T. asiatica hybrid in Yunnan Province. Molecular evidence suggests that the hybrid of T. saginata and T. asiatica may have caused widespread infection in rural areas of Western China, and further investigation and research on these parasites in Western China are needed.
