It is important to establish the benign or malignant nature of the stricture early in order to avoid any unnecessary delay in medical treatment or surgery. Tissue acquisition for histological diagnosis is particularly crucial when the initial diagnostic work up is inconclusive. The diagnostic yield from the conventional endoscopic retrograde cholangiopancreatography (ERCP) with brushing and biopsy is suboptimal. Patients with indeterminate biliary strictures (IDBSs) often require a multi-disciplinary diagnostic approach and additional endoscopic evaluation, including cholangioscopy and endoscopic ultrasound, before a final diagnosis can be reached. In this article, we discuss the recent endoscopic advancements in the diagnosis of biliary stricture with a focus on the roles of cholangioscopy and endoscopic ultrasound (EUS).","PeriodicalId":43586,"journal":{"name":"Gastroenterology Insights","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45640538","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}

Specifically, recent guidelines have highlighted pre-procedural, peri-procedural, and post-procedural practices, which promise to improve patient outcomes and reduce the mortality and interval cancer rates in patients undergoing colonoscopies. Despite the guidelines and advances in modern endoscopy, the procedure remains provider-dependent, which results in differences in outcomes. As a result, incorporating high-quality colonoscopy approaches early in training is key to improving patient outcomes.

Non-alcoholic steatohepatitis (NASH), an advanced form of NAFLD, accompanies the progression of hepatic steatosis, inflammation, cell death, and varying degree of liver fibrosis. Interferons (IFNs) have been shown to play important roles in the pathogenesis of NAFLD and NASH. Their regulating transcriptional factors such as interferon regulatory factors (IRFs) can regulate IFN expression, as well as genes involved in macrophage polarization, which are implicated in the pathogenesis of NAFLD and advanced liver disease. In this review, the roles of IRF-involved signaling pathways in hepatic inflammation, insulin resistance, and immune cell activation are reviewed. IRFs such as IRF1 and IRF4 are also involved in the polarization of macrophages that contribute to critical roles in NAFLD or NASH pathogenesis. In addition, IRFs have been shown to be regulated by treatments including microRNAs, PPAR modulators, anti-inflammatory agents, and TLR agonists or antagonists. Modulating IRF-mediated factors through these treatments in chronic liver disease can ameliorate the progression of NAFLD to NASH. Furthermore, adenoviruses and CRISPR activation plasmids can also be applied to regulate IRF-mediated effects in chronic liver disease. Pre-clinical and clinical trials for evaluating IRF regulators in NAFLD treatment are essential in the future direction.","PeriodicalId":43586,"journal":{"name":"Gastroenterology Insights","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41795854","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}

We aimed to determine the percentage of acute kidney injury in decompensated cirrhosis patients and evaluate the treatment results of acute kidney injury as well as several factors related to the mortality of decompensated cirrhosis patients. Methods: A prospective study was conducted on decompensated cirrhosis patients in Can Tho City, Vietnam, from 2019 to 2020. Decompensated cirrhosis patients were found to have acute kidney injury on admission by a blood creatinine test. They were treated according to ICA 2015 standards, after which they were monitored and evaluated for treatment outcomes during hospitalization. Results: Of 250 decompensated cirrhosis patients, 64 (25.6%) had acute kidney injury and 37.5% died. Several factors were associated with mortality in decompensated cirrhosis patients, such as Child–Pugh C (p = 0.02; OR = 3, 95% CI 1.5–6.3), acute kidney injury (p < 0.0001; OR = 9.5, 95% CI 4.3–21.1), hyponatremia (p = 0.01; OR = 2.5, 95% CI 1.2–5.1), elevated total bilirubin > 51 µmol/L (p = 0.03; OR = 2.2, 95% CI 1.1–4.6), and prothrombin < 70% (p = 0.03; OR = 6.8, 95% CI 1–51.6). Hypoalbuminemia was unrelated to mortality in these patients (p = 0.8; OR = 1.2, 95% CI 0.5–2.7), but gastrointestinal bleeding significantly increased mortality in these patients up to 2.3 times (p = 0.03; OR = 2.3, 95% CI 1.1–4.9). Three independent factors regarding mortality in decompensated cirrhosis patients included acute kidney injury, hepatic encephalopathy, and gastrointestinal bleeding. The rate of acute kidney injury in patients with decompensated cirrhosis was 25.6%; the mortality rate was 37.5%.

Methods: We conducted an observational cross-sectional study, for a period of two months, among 180 resident doctors specializing in gastroenterology, working in university hospitals in Romania. A questionnaire consisting of 29 questions distributed through social media platforms was completed in Google Forms. Statistical analyses were performed using IBM SPSS software v.20. Results: A linear relationship was identified between the number of daily hospitalizations in the gastroenterology department and the rate of SARS-CoV-2 infection among resident physicians. In total, 80% of the participants reported an increase in the levels of stress, anxiety, and depression during the COVID-19 pandemic, and 88.3% stated that they were unsatisfied by online courses. Conclusions: The COVID-19 pandemic has had negative effects on both professional training and levesl of stress, anxiety and depression of resident doctors specializing in gastroenterology.

Dietary approaches, such as fiber enrichment during and after pelvic radiotherapy, have been suggested to prevent or reduce dysfunctions. In the present paper, we aimed to investigate whether a diet rich in fermentable fiber could have a positive effect on radiation-induced intestinal damage, especially focusing on tuft cells and enteric neurons. Male C57BL/6 mice were fed either a purified non-fiber diet or the same purified diet with 5% or 15% oat fiber added, starting two weeks prior to sham-irradiation or irradiation with four fractions of 8 Gray. The animals continued on the diets for 1, 6 or 18 weeks, after which the gross morphology of the colorectum was assessed together with the numbers of enteric neurons, tuft cells and crypt-surface units. The results showed that dietary fiber significantly affected the intestinal morphometrics, both in the short and long-term. The presence of dietary fiber stimulated the re-emergence of crypt-surface unit structures after irradiation. At 18 weeks, the animals fed with the non-fiber diet displayed more myenteric neurons than the animals fed with the dietary fibers, but irradiation resulted in a loss of neurons in the non-fiber fed animals. Irradiation, but not diet, affected the tuft cell numbers, and a significant increase in tuft cells was found 6 and 18 weeks after irradiation. In conclusion, dietary fiber intake has the potential to modify neuronal pathogenesis in the colorectum after irradiation. The long-lasting increase in tuft cells induced by irradiation may reflect an as yet unknown role in the mucosal pathophysiology after pelvic irradiation.","PeriodicalId":43586,"journal":{"name":"Gastroenterology Insights","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2022-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49003566","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}
