- Abstract
Aims: Colon preparation is vital yet more difficult in elderly patients with severe lower gastrointestinal bleeding (LGIB). The aim of this study is to show the efficacy, safety and outcomes of unprepared polyethylene glycol (PEG)-flush retrograde colon cleansing in the diagnosis and treatment of elderly home care patients with LGIB., Methods: A single-center study was performed between January 2014 and June 2018. Elderly home healthcare patients presenting with hematochezia were enrolled, and an unprepared retrograde bowel cleansing colonoscopy was performed within the first 8 h after admission to the emergency department. PEG solution (2 L) was added to the water jet tank, and jet pump injection was started from the left side of the colon to the right segment of the colon and ended up at the cecum., Results: In total, 33 elderly patients presenting with hematochezia were evaluated. Mean inward and outward procedure times were 17.06 ± 4.92 (8-33 min) and 28.66 ± 6.88 (10-30 min), respectively. Most of the bleeding was localized in the right colon at 22 patients (66.3%). Endoscopic treatment was performed in 87.9% of patients. The average length of stay in hospital was 44.70 ± 42.81 (range 18.00-240.00 h)., Conclusions: Immediate unprepared PEG-flush colonoscopy in elderly home care patients with acute LGIB is a safe and effective method, which detects bleeding sources and provides endoscopic therapy. With this procedure, the time of hospital stay is reduced. This approach may be used for the initial intervention in patients admitted to emergency departments or intensive care unit with severe acute LGIB.

- Abstract
Background: The discrimination of malignant biliary strictures from benign biliary diseases (BBDs) is challenging and complicated. We aimed to investigate whether Resolvin D1 (RvD1) would aid in the discrimination of cholan-giocarcinoma (CCA) from BBDs., Methods: Thirty-one patients with CCA, 27 patients with BBD, and 30 healthy controls were enrolled in this cross-sectional study. The diagnosis of CCA was based on results obtained from abdominal USG, MRCP, abdominal CT, endosonography, and tumor markers, including CEA and CA 19-9. Histopathological evaluation was performed in the majority of patients, and the final diagnosis was based on surgery or biopsy results. RvD1, CEA, and CA 19-9 were analyzed in all patients with CCA and BBD., Results: RvD1 was significantly lower in those with CCA compared to patients with BBD and healthy controls. In addition, CEA and Ca 19-9 levels were significantly higher in the CCA group than the BBD group (p < 0.001). RvD1 concentration, CA 19-9 concentration, and total bilirubin level were found to be correlated with tumor stage (r = -0.702, 0.390, and 0.569, respectively). ROC curve analysis revealed that an RvD1 concentration of < 380 ng/mL (AUC: 0.783, 95% CI: 0673 - 0.893, p < 0.001) and CA 19-9 concentration of > 94.5 U/mL (AUC: 0.94, 95% CI: 0.898 - 0.998, p < 0.001) could be used to discriminate patients with CCA from those with BBD., Conclusions: Resolvin D1 and CA 19-9 levels might be used to effectively discriminate between BBD and CCA. Moreover, both RvD1 and CA 19-9 levels are associated with the stage of CCA, indicating that they may also be used in assessing disease progression.

- Abstract
Background: We hypothesized that nesfatin-1, an anti-inflammatory peptide, could be used as a non-invasive diagnostic tool in the identification of celiac disease (CD) and irritable bowel syndrome presenting predominantly with diarrhea (IBS-D)., Methods: Thirty-five patients with IBS-D who met the Rome III criteria, 28 patients with celiac disease who met the diagnostic criteria of the Marsh-Oberhuber classification, and 30 age- and gender-matched healthy controls were included in this cross-sectional study. All subjects responded to the IBS Severity Scoring System (IBS-SSS) questionnaire that was used to determine pain severity, pain frequency, bloating, dissatisfaction with bowel habits, and life interference., Results: Nesfatin-1 levels were significantly higher in the CD group compared to the IBS-D group and healthy controls. Nesfatin-1 was also higher in the IBS-D group compared to controls. Nesfatin-1 levels were correlated with IBS-SSS (r = 0.884, p < 0.001), severity of abdominal pain and discomfort (r = 0.644, p < 0.001), and C-reactive protein concentrations (r = 0.303, p = 0.004). ROC curve analysis demonstrated that a cutoff value of > 98.1 pg/mL for nesfatin-1 could discriminate subjects with CD from those with IBS-D and also healthy controls with a sensitivity of 82% and a specificity of 80%., Conclusions: The results of this study show that subjects with CD have higher nesfatin-1 levels compared to those with IBS-D or to the healthy controls. Moreover, nesfatin-1 can discriminate subjects with CD from those with IBS-D and also healthy controls, with high sensitivity and specificity. Further studies with histopathological evaluation are required to clearly address the role of nesfatin-1 in the diagnosis of CD.

- Abstract
Background/aim: This study was designed to identify the effect of pentoxifylline on trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats., Materials and Methods: Forty-two female Wistar rats were randomly divided into 7 groups: group A, TNBS + intraperitoneal (IP) pentoxifylline; group B, TNBS + IP saline; group C, TNBS + intrarectal (IR) pentoxifylline; group D, TNBS + IR saline; group E, IP pentoxifylline + TNBS; group F, IP saline + TNBS; group G, IR saline. Pentoxifylline was given daily for 3 days before or 6 days after the induction of colitis. Rats were killed after 6 days., Results: IP and IR pentoxifylline similarly and significantly reduced damage and histopathological scores. Pentoxifylline attenuated the accumulation of malonyldialdehyde and transforming growth factor β1 and the activities of myeloperoxidase, matrix metalloproteinase-3, and tissue inhibitor of metalloproteinases-1, and it also restored superoxide dismutase activity. The IP route was more effective than the IR route in this regard. Administration of IP pentoxifylline before or after induction did not influence all parameters. Conclusions: Pentoxifylline showed a therapeutic effect in this experimental colitis model. IP administration seemed to be better. This effect may occur as a result of inhibition of oxidative stress and metalloproteinase activity.

- Abstract
Background/aims: The Wnt/ß-catenin pathway plays a prominent role in hepatocellular carcinoma (HCC). The Dickkopf (DKK) proteins (DKK1-4) are known Wnt antagonists; the overexpression of DKK1 has been demonstrated in HCC, and increased DKK3 methylation in the HCC tissue is associated with worse prognosis. Thus, the aim of our study was to demonstrate the diagnostic accuracy of serum DKK1 and DKK3 in HCC in comparison with that of serum alpha-fetoprotein (AFP)., Materials and Methods: We included consecutive 40 HCC patients, 54 cirrhosis patients, and 39 healthy controls. Serum DKK1 and DKK3 levels were measured by an enzyme-linked immunosorbent assay, and serum AFP levels were measured by a chemiluminescence assay., Results: The AFP levels differed in each group and could help differentiate between groups (p < 0.001). The DKK1 levels could help differentiate the HCC group from cirrhosis and control groups (p < 0.001), and the DKK3 levels could help differentiate HCC and cirrhosis groups from the control group (p < 0.001). Combined usage of DKK1 and AFP increased the diagnostic yield, with a sensitivity, specificity, positive predictive value, and negative predictive value of 87.5%, 92.3%, 92.1%, and 87.8%, respectively., Conclusion: Although AFP is superior to DKK1 and DKK3 in the diagnosis of HCC, the combination of DKK1 and AFP showed a better diagnostic yield than AFP alone.

As a hepatotropic virus, hepatitis B virus (HBV) can establish a persistent chronic infection in the liver, termed, chronic hepatitis B (CHB), which causes a series of liver-related complications, including fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). HCC with HBV infection has a significantly increased morbidity and mortality, whereas it could be preventable. The current goal of antiviral therapy for HBV infection is to decrease CHB-related morbidity and mortality, and achieve sustained suppression of virus replication, which is known as a functional or immunological cure. The natural history of chronic HBV infection includes four immune phases: the immune-tolerant phase, immune-active phase, inactive phase, and reactivation phase. However, many CHB patients do not fit into any of these defined phases and are regarded as indeterminate. A large proportion of indeterminate patients are only treated with dynamic monitoring rather than recommended antiviral therapy, mainly due to the lack of definite guidelines. However, many of these patients may gradually have significant liver histopathological changes during disease progression. Recent studies have focused on the prevalence, progression, and carcinogenicity of indeterminate CHB, and more attention has been given to the prevention, detection, and treatment for these patients. Herein, we discuss the latest understanding of the epidemiology, clinical characteristics, and therapeutic strategies of indeterminate CHB, to provide avenues for the management of these patients.

Background and aims: Emergency endoscopic hemostasis for colonic diverticular bleeding is effective in preventing serious consequences. However, the low identification rate of the bleeding source makes the procedure burdensome for both patients and providers. We aimed to establish an efficient and safe emergency endoscopy system. Methods: We prospectively evaluated the usefulness of a scoring system (Jichi Medical University diverticular hemorrhage score: JD score) based on our experiences with past cases. The JD score was determined using four criteria: CT evidence of contrast agent extravasation, 3 points; oral anticoagulant (any type) use, 2 points; C-reactive protein ≥1 mg/dL, 1 point; and comorbidity index ≥3, 1 point. Based on the JD score, patients with acute diverticular bleeding who underwent emergency or elective endoscopy were grouped into JD ≥3 or JD <3 groups, respectively. The primary and secondary endpoints were the bleeding source identification rate and clinical outcomes. Results: The JD ≥3 and JD <3 groups included 35 and 47 patients, respectively. The rate of bleeding source identification, followed by the hemostatic procedure, was significantly higher in the JD ≥3 group than in the JD <3 group (77% vs. 23%, p <0.001), with a higher JD score associated with a higher bleeding source identification rate. No significant difference was observed between the groups in terms of clinical outcomes, except for a higher incidence of rebleeding at one-month post-discharge and a higher number of patients requiring interventional radiology in the JD ≥3 group than in the JD <3 group. Subgroup analysis showed that successful identification of the bleeding source and hemostasis contributed to a shorter hospital stay. Conclusion: We established a safe and efficient endoscopic scoring system for treating colonic diverticular bleeding. The higher the JD score, the higher the bleeding source identification, leading to a successful hemostatic procedure. Elective endoscopy was possible in the JD <3 group when vital signs were stable.

INFLAMMATION ,CARCINOGENESIS ,CAFFEINE - Abstract
Caffeine (1,3,7-trimethylxanthine, also abbreviated to CAF) is a natural chemical with stimulant effects and is commonly included in many drinks and foods, including coffee, tea, cola, energy drinks, cocoa, chocolates, and so on. Our group previously reported that oral administration of CAF efficiently suppressed the development of intestinal inflammation in a dextran sulfate sodium (DSS)-induced murine acute colitis model by suppressing the expression of chitinase 3-like 1, one of the mammalian chitinases without enzymatic activity. Chitinases are hydrolytic enzymes that break down chitin, a polymer of N-acetylglucosamine, and chitinase-like proteins have no enzymatic activity with preserving chitin-binding ability. CAF binds a cleft of the chitinase active site and plays a role as a pan-chitinase inhibitor. Although CAF showed an anti-inflammatory effect in the above model, oral administration of low-dose CAF with 10% sucrose showed potentially neoplastic effects in colonic epithelial cells in a DSS-induced murine chronic colitis model. In this review, we would like to discuss the pros and cons of coffee/CAF in colonic inflammation and neoplasia with an example of pathological finding. [ABSTRACT FROM AUTHOR]

Background: Although intestinal fibrosis is a consequence of recurrent inflammation in Inflammatory bowel disease (IBD), alleviating inflammation alone does not prevent the progression of fibrosis, suggesting that the development of direct anti-fibrotic agents is necessary. This study aimed to evaluate the anti-fibrotic properties of combination treatment with pentoxifylline (PTX) and vitamin E (Vit-E) on human primary intestinal myofibroblasts (HIMFs) and the therapeutic potential of the combination therapy in murine models of IBD. Methods: HIMFs were pretreated with PTX, Vit-E, or both, and incubated with TGF-β1. We performed Western blot, qPCR, collagen staining, and immunofluorescence to estimate the anti-fibrotic effects of PTX and Vit-E. The cytotoxicity of these was investigated through MTT assay. To induce murine models of IBD for in vivo study, C57BL/6 mice were treated with repeated cycles of dextran sulfate sodium (DSS), developing chronic colitis. We examined whether the combined PTX and Vit-E treatment would effectively ameliorate colonic fibrosis in vivo. Results: We found that the co-treatment with PTX and Vit-E suppressed TGF-β1-induced expression of fibrogenic markers, with decreased expression of pERK, pSmad2, and pJNK, more than either treatment alone in HIMFs. Neither PTX nor Vit-E showed any significant cytotoxicity in given concentrations. Consistently with the in vitro results, the co-administration with PTX and Vit-E effectively attenuated colonic fibrosis with recovery from thickening and shortening of colon in murine models of IBD. Conclusions: These findings demonstrated that the combination of PTX and Vit-E exhibits significant anti-fibrotic effects in both HIMFs and in vivo IBD models, providing a promising therapy for IBD.

Objective. We previously described that different concentration Nucleobindin-2 (NUCB2)/Nesfatin-1 gradients differently regulated visceral hypersensitivity in irritable bowel syndrome. Therefore, this study is aimed at evaluating the effect of NUCB2/Nesfatin-1 on model rats with chronic visceral hyperalgesia. Methods. Neonatal and mature Sprague-Dawley rats were randomly divided into the healthy control and chronic visceral hyperalgesia model groups. The model was built by combining maternal separation with the acetic acid enema. The models were identified by the distension volume threshold to reach abdominal withdraw reflex AWR score = 3 , histological staining, and myeloperoxidase (MPO) detection. The visceral sensitivity to chronic visceral hyperalgesia was then evaluated. Result. Rats in the model group responded more strongly to pulling stimulation than healthy controls; the distension volume threshold causing AWR3 response in model rats was lower than the control group before NUCB2/Nesfatin-1 intervention. After intervention, the distension volume threshold was significantly lower in the NUCB2/Nesfatin-1 central intervention group than in the NUCB2/Nesfatin-1 peripheral intervention group, and the peak value of external oblique muscle electrical activity was significantly higher. Additionally, compared with the male intervention group, in the female intervention group, the volume threshold was significantly lower and the peak value was higher. Conclusion. NUCB2/Nesfatin-1 could regulate visceral sensitivity in chronic visceral hyperalgesia model rats; its regulatory effect correlated with the type of NUCB2/Nesfatin-1 intervention approaches (central or peripheral) and sex (male or female).

Cholangiocarcinoma is an uncommon and highly aggressive biliary tract malignancy with few manifestations until late disease stages. Diagnosis is currently achieved through a combination of clinical, biochemical, radiological and histological techniques. A number of reported cancer biomarkers have the potential to be incorporated into diagnostic pathways, but all lack sufficient sensitivity and specificity limiting their possible use in screening and early diagnosis. The limitations of standard serum markers such as CA19-9, CA125 and CEA have driven researchers to identify multiple novel biomarkers, yet their clinical translation has been slow with a general requirement for further validation in larger patient cohorts. We review recent advances in the diagnostic pathway for suspected CCA as well as emerging diagnostic biomarkers for early detection, with a particular focus on non-invasive approaches.

1: ESGE recommends that the initial assessment of patients presenting with acute lower gastrointestinal bleeding should include: a history of co-morbidities and medications that promote bleeding; hemodynamic parameters; physical examination (including digital rectal examination); and laboratory markers. A risk score can be used to aid, but should not replace, clinician judgment.Strong recommendation, low quality evidence. 2 : ESGE recommends that, in patients presenting with a self-limited bleed and no adverse clinical features, an Oakland score of ≤ 8 points can be used to guide the clinician decision to discharge the patient for outpatient investigation.Strong recommendation, moderate quality evidence. 3 : ESGE recommends, in hemodynamically stable patients with acute lower gastrointestinal bleeding and no history of cardiovascular disease, a restrictive red blood cell transfusion strategy, with a hemoglobin threshold of ≤ 7 g/dL prompting red blood cell transfusion. A post-transfusion target hemoglobin concentration of 7-9 g/dL is desirable.Strong recommendation, low quality evidence. 4 : ESGE recommends, in hemodynamically stable patients with acute lower gastrointestinal bleeding and a history of acute or chronic cardiovascular disease, a more liberal red blood cell transfusion strategy, with a hemoglobin threshold of ≤ 8 g/dL prompting red blood cell transfusion. A post-transfusion target hemoglobin concentration of ≥ 10 g/dL is desirable.Strong recommendation, low quality evidence. 5: ESGE recommends that, in patients with major acute lower gastrointestinal bleeding, colonoscopy should be performed sometime during their hospital stay because there is no high quality evidence that early colonoscopy influences patient outcomes.Strong recommendation, low quality of evidence. 6 : ESGE recommends that patients with hemodynamic instability and suspected ongoing bleeding undergo computed tomography angiography before endoscopic or radiologic treatment to locate the site of bleeding.Strong recommendation, low quality evidence. 7 : ESGE recommends withholding vitamin K antagonists in patients with major lower gastrointestinal bleeding and correcting their coagulopathy according to the severity of bleeding and their thrombotic risk. In patients with hemodynamic instability, we recommend administering intravenous vitamin K and four-factor prothrombin complex concentrate (PCC), or fresh frozen plasma if PCC is not available.Strong recommendation, low quality evidence. 8 : ESGE recommends temporarily withholding direct oral anticoagulants at presentation in patients with major lower gastrointestinal bleeding.Strong recommendation, low quality evidence. 9: ESGE does not recommend withholding aspirin in patients taking low dose aspirin for secondary cardiovascular prevention. If withheld, low dose aspirin should be resumed, preferably within 5 days or even earlier if hemostasis is achieved or there is no further evidence of bleeding.Strong recommendation, moderate quality evidence. 10: ESGE does not recommend routinely discontinuing dual antiplatelet therapy (low dose aspirin and a P2Y12 receptor antagonist) before cardiology consultation. Continuation of the aspirin is recommended, whereas the P2Y12 receptor antagonist can be continued or temporarily interrupted according to the severity of bleeding and the ischemic risk. If interrupted, the P2Y12 receptor antagonist should be restarted within 5 days, if still indicated.Strong recommendation, low quality evidence. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) accounts for 90% of cases of liver cancer and is one of the most common and lethal malignancies among all cancers. Current screening practices in high‐risk populations using ultrasound and serological α‐fetoprotein (AFP) have significantly reduced HCC mortality. However, considering the highly operative‐dependent nature of ultrasound and dissatisfactory diagnostic performance of AFP, there is an unfulfilled need for a biomarker that can be used in HCC‐related at‐risk population screening. Here, sera from 322 patients, including 105 cases of chronic hepatitis (CH), 116 of liver cirrhosis (LC), and 101 of HCC, were collected. Two biomarkers, osteopontin (OPN) and dickkopf WNT signaling pathway inhibitor 1 (DKK1), were evaluated and compared with AFP alone and in combination. In our data, the serum OPN level increased significantly in HCC even in tumors of less than 2 cm. The area under the curve (AUC) reached 0.851, much higher than AFP and DKK1, with 79.21% sensitivity and 79.64% specificity at optimal cutoff in all of the samples. In AFP‐negative samples, serum OPN also performed well with an AUC of 0.838. The combination of AFP and OPN improved diagnosis performance significantly when compared with AFP alone. However, the DKK1 level showed an increase in HCC only compared with the LC group. The AUC does not improve significantly when added into the binary logistic model. We conclude that OPN, but not DKK1, is a promising biomarker for HCC diagnosis. Research Highlights: Serological OPN shows higher value in diagnosing hepatocellular carcinoma comparing with AFP and DKK1, with AUC at 0.851 in all of the 322 patients.In AFP negative samples, serum OPN also performs well with an AUC of 0.838.In tumor smaller than 2cm, OPN shows a significant increase, suggests its high clinical value in HCC screening and diagnosis.

- Abstract
Acute lower gastrointestinal bleeding (LGIB) is a common reason for hospitalization in the United States and is associated with significant utilization of hospital resources, as well as considerable morbidity and mortality. These revised guidelines implement the Grading of Recommendations, Assessment, Development, and Evaluation methodology to propose recommendations for the use of risk stratification tools, thresholds for red blood cell transfusion, reversal agents for patients on anticoagulants, diagnostic testing including colonoscopy and computed tomography angiography (CTA), endoscopic therapeutic options, and management of antithrombotic medications after hospital discharge. Important changes since the previous iteration of this guideline include recommendations for the use of risk stratification tools to identify patients with LGIB at low risk of a hospital-based intervention, the role for reversal agents in patients with life-threatening LGIB on vitamin K antagonists and direct oral anticoagulants, the increasing role for CTA in patients with severe LGIB, and the management of patients who have a positive CTA. We recommend that most patients requiring inpatient colonoscopy undergo a nonurgent colonoscopy because performing an urgent colonoscopy within 24 hours of presentation has not been shown to improve important clinical outcomes such as rebleeding. Finally, we provide updated recommendations regarding resumption of antiplatelet and anticoagulant medications after cessation of LGIB., (Copyright © 2022 by The American College of Gastroenterology.)

Background: Hepatocellular carcinoma (HCC) is a highly fatal tumor which represents a major health problem worldwide. Due to asymptomatic nature of HCC, most patients present with the progressive stage of disease, so, unfortunately, there are no effective therapies. Existing techniques for HCC surveillance and diagnosis lack the required accuracy. Therefore, searching for new diagnostic and/or therapeutic tools could improve patient survival. This study aimed to estimate the diagnostic role of Dickkopf-1 (DKK1) and amphiregulin (AREG) and to find out their correlation with different clinicopathological parameters in HCC patients. Materials and Methods: Serum levels of DKK1 and AREG in 55 HCC patients, 20 cirrhotic patients, and 15 healthy subjects as control group were measured using the ELISA technique. Results: Both of DKK1 and AREG showed a significant increase in the HCC group compared to cirrhotic and healthy groups. DKK1 at a cutoff point of 8.92 ng/ml showed that the area under the curve (AUC) was 0.826 with 87.3% sensitivity and 82.9% specificity. DKK1 showed a significant correlation with tumor size, liver dysfunction, and poor performance status in HCC patients. AREG at a cutoff point of 8.74 pg/ml showed a sensitivity of 74.5% but low specificity (47.1%). AREG showed a significant correlation with portal vein thrombosis and tumor metastasis in HCC patients. Conclusion: Serum DKK1 could be a diagnostic biomarker for HCC. Both of DKK1 and AREG may play significant roles in tumor progression and may offer promising therapeutic targets in HCC patients.

Intestinal inflammation is the collective term for immune system-mediated diseases of unknown, multifactorial etiology, with often complex interactions between genetic and environmental factors. To mechanistically investigate the effect of treatment with compounds possessing immunomodulating properties in the context of intestinal inflammation, we developed an immunocompetent in vitro triculture intestinal model consisting of a differentiated intestinal epithelial layer (Caco-2/HT29-MTX) and immunocompetent cells (differentiated THP-1). The triculture mimicked a healthy intestine with stable barrier integrity. Lipopolysaccharide treatment triggered a controlled and reversible inflammatory state, resulting in significant impairment of barrier integrity and release of pro-inflammatory cytokines and chemokines, which are known hallmarks of intestinal inflammation. Treatment with known anti-inflammatory reference compounds (TPCA-1 and budenoside) prevented the induction of an inflammatory state; the decreasing triculture responses to this treatment measured by cytokine release, transepithelial electric resistance (TEER), and epithelial layer permeability proved the suitability of the intestinal model for anti-inflammatory drug screening. Finally, selected tobacco alkaloids (nicotine and anatabine (R / S and S forms)) were tested in the in vitro triculture for their potential anti-inflammatory properties. Indeed, naturally occurring alkaloids, such as tobacco-derived alkaloids, have shown substantial anti-inflammatory effects in several in vitro and in vivo models of inflammation, gaining increasing interest. Similar to the anti-inflammatory reference compounds, one of the tobacco alkaloids under investigation partially prevented the decrease in the TEER and increase in permeability and reduced the release of pro-inflammatory cytokines and chemokines. Taken together, these data confirm that our in vitro model is suitable for screening potential anti-inflammatory compounds in the context of intestinal inflammation. [ABSTRACT FROM AUTHOR]
