Abstract
PURPOSE Aspirin reduces the incidence of various gastrointestinal (GI) malignancies. This meta-analysis assessed the efficacy and safety of regular aspirin use on the incidence of hepatocellular carcinoma (HCC) in patients with chronic liver disease. METHODS Electronic reference databases were searched for studies in patients with chronic liver disease exposed to aspirin. The primary outcome was the incidence of HCC in regular aspirin users compared to non-users. The secondary outcome was the incidence of major GI bleeding events in both groups. The propensity score (PS) and non-PS-adjusted pooled hazard ratio (HR) were calculated using random-effects models. RESULTS Six observational studies with 71,211 subjects were included. The median duration of follow-up ranged from 2.7 to 7.9 years. Four studies included patients with viral hepatitis; five studies used aspirin 100 mg/day. All six studies reported the non-PS-matched HR, and there was a 54% reduction in the incidence of HCC among regular aspirin users [HR (95% CI): 0.46(0.31-0.67), p < 0.001]. Four studies reported on the PS-matched HR; this showed a 46% reduced incidence of HCC in those using aspirin [HR (95% CI): 0.54(0.38-0.79), p < 0.001]. Subgroup analysis on studies restricted to viral hepatitis (n = 4) showed a 28% reduction in HCC incidence in aspirin users [HR (95% CI): 0.72(0.64-0.80), p < 0.001]. Four studies reported the incidence of major GI bleeds, there was no significant difference between the two groups [HR (95% CI: 1.00(0.69-1.45), p = 0.90]. All outcome analysis, except the subgroup analysis, had significant inter-study heterogeneity. CONCLUSION Regular aspirin use in chronic liver disease is associated with reduced incidence of HCC without increasing the risk of major GI bleeding.

Abstract
Background and Aims Artificial Intelligence (AI) is rapidly evolving in gastrointestinal (GI) endoscopy. We undertook a systematic review and meta-analysis to assess the performance of AI at detecting early Barrett's neoplasia. Methods We searched Medline, EMBASE and Cochrane Central Register of controlled trials database from inception to the 28th Jan 2022 to identify studies on the detection of early Barrett's neoplasia using AI. Study quality was assessed using Quality Assessment of Diagnostic Accuracy Studies – 2 (QUADAS-2). A random-effects model was used to calculate pooled sensitivity, specificity, and diagnostics odds ratio (DOR). Forest plots and a summary of the receiving operating characteristics (SROC) curves displayed the outcomes. Heterogeneity was determined by I2, Tau2 statistics and p-value. The funnel plots and Deek's test were used to assess publication bias. Results Twelve studies comprising of 1,361 patients (utilizing 532,328 images on which the various AI models were trained) were used. The SROC was 0.94 (95% CI: 0.92–0.96). Pooled sensitivity, specificity and diagnostic odds ratio were 90.3% (95% CI: 87.1–92.7%), 84.4% (95% CI: 80.2–87.9%) and 48.1 (95% CI: 28.4–81.5), respectively. Subgroup analysis of AI models trained only on white light endoscopy was similar with pooled sensitivity and specificity of 91.2% (95% CI: 85.7–94.7%) and 85.1% (95% CI: 81.6%−88.1%), respectively. Conclusions AI is highly accurate at detecting early Barrett's neoplasia and validated for patients with at least high-grade dysplasia and above. Further well-designed prospective randomized controlled studies of all histopathological subtypes of early Barrett's neoplasia are needed to confirm these findings further.

Abstract
The role of endoscopic procedures, in both diagnostic and therapeutic purposes is continually expanding and evolving rapidly. In this context, endoscopists will encounter patients prescribed on anticoagulant and antiplatelet medications frequently. This poses an increased risk of intraprocedural and delayed gastrointestinal bleeding. Thus, there is now greater importance on optimal pre, peri and post-operative management of anticoagulant and/or antiplatelet therapy to minimise the risk of post-procedural bleeding, without increasing the risk of a thromboembolic event as a consequence of therapy interruption. Currently, there are position statements and guidelines from the major gastroenterology societies. These are available to assist endoscopists with an evidenced-based systematic approach to anticoagulant and/or antiplatelet management in endoscopic procedures, to ensure optimal patient safety. However, since the publication of these guidelines, there is emerging evidence not previously considered in the recommendations that may warrant changes to our current clinical practices. Most notably and divergent from current position statements, is a growing concern regarding the use of heparin bridging therapy during warfarin cessation and its associated risk of increased bleeding, suggestive that this practice should be avoided. In addition, there is emerging evidence that anticoagulant and/or antiplatelet therapy may be safe to be continued in cold snare polypectomy for small polyps (< 10 mm).

Abstract
In March 2016, the Australian government offered unrestricted access to direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) to the entire population. This included prescription by any medical practitioner in consultation with specialists until sufficient experience was attained. We sought to determine the outcomes and experience over the first twelve months for the entire state of South Australia. We performed a prospective, observational study following outcomes of all treatments associated with the state's four main tertiary centres. A total of 1909 subjects initiating DAA therapy were included, representing an estimated 90% of all treatments in the state. Overall, SVR12 was 80.4% in all subjects intended for treatment and 95.7% in those completing treatment and follow-up. 14.2% were lost to follow-up (LTFU) and did not complete SVR12 testing. LTFU was independently associated with community treatment via remote consultation (OR 1.50, 95% CI 1.04-2.18, P = .03), prison-based treatment (OR 2.02, 95% CI 1.08-3.79, P = .03) and younger age (OR 0.98, 95% CI 0.97-0.99, P = .05). Of the 1534 subjects completing treatment and follow-up, decreased likelihood of SVR12 was associated with genotype 2 (OR 0.23, 95% CI 0.07-0.74, P = .01) and genotype 3 (OR 0.23, 95% CI 0.12-0.43, P ≤ .01). A significant decrease in treatment initiation was observed over the twelve-month period in conjunction with a shift from hospital to community-based treatment. Our findings support the high responses observed in clinical trials; however, a significant gap exists in SVR12 in our real-world cohort due to LTFU. A declining treatment initiation rate and shift to community-based treatment highlight the need to explore additional strategies to identify, treat and follow-up remaining patients in order to achieve elimination targets.

Abstract
BACKGROUND Vascular disease is a common cause of death in patients with chronic hepatitis C (CHC) infection; however, the association between CHC and atherosclerosis is unclear. AIMS To determine whether patients with CHC have increased subclinical vascular disease and whether genotype or antiviral treatment modifies this risk. METHODS Fifty CHC patients and 22 age-matched and sex-matched healthy controls underwent clinical and biochemical assessment for vascular risk factors. In addition, vascular risk was assessed by measuring arterial stiffness (aortic augmentation index and carotid-femoral pulse wave velocity (PWV)), endothelial dysfunction (brachial artery flow-mediated dilatation (FMD) and dilatation post-glycerol trinitrate administration) and carotid intima-media thickness (CIMT). Assessment was repeated in subset of CHC patients (n = 12) undergoing antiviral treatment 18 months after initiation of treatment. RESULTS Baseline vascular risk factors and measures of arterial stiffness, endothelial dysfunction and CIMT were not different between cases and controls (P > 0.2 for all). Genotype 1 CHC patients had greater endothelial dysfunction with lower FMD (8.2 ± 3.5% vs 10.9 ± 5.2%, P = 0.03) and higher right CIMT (0.6 ± 0.1 mm vs 0.5 ± 0.07 mm, P = 0.04) compared with non-genotype 1. Patients who achieved sustained virological response (7/12) showed significant improvement in insulin resistance (homeostasis model of assessment of insulin resistance 2.3 ± 1.2 vs 1.8 ± 0.8, P = 0.02) and arterial stiffness (PWV 7.4 ± 1.1 m/s vs 6.5 ± 0.6 m/s, P = 0.04). CONCLUSIONS Subclinical vascular disease is not greater in CHC subjects compared with controls. However, among CHC subjects, genotype 1 infection is associated with greater endothelial dysfunction and increased carotid-intima medial thickness compared with non-genotype 1 infection. Successful viral eradication may improve insulin resistance and arterial stiffness.

Abstract
BACKGROUND Hepatic osteodystrophy (HO) is a major complication of cirrhosis. However, the prevalence of HO in a general cirrhotic patient population is not well defined as previous studies were in single aetiology or pre-liver transplant patients. AIMS The aims of this study were to investigate the prevalence of HO and vitamin D deficiency in patients with cirrhosis of mixed aetiology and disease severity and to determine the risk factors for HO. METHODS This is a single-centre cross-sectional study of all patients newly diagnosed with cirrhosis between September 2009 and December 2012. All patients underwent bone mineral density assessment using dual energy X-ray absorptiometry within 3 months of diagnosis. Demographic and biochemical factors, severity of underlying liver disease, previous fragility fractures, smoking status and alcohol use were collected on diagnosis. Logistic regression analysis was used to assess risk factors for HO. RESULTS Among the 406 patients (67% males), the median (range) age was 56 years (21-85) and most (84%) were Childs-Pugh A or B with a median (range) model for end-stage liver disease score of 11 (5-40). Alcohol (41%) was the most common underlying aetiology. The prevalence of HO and vitamin D deficiency (≤50 nmol/L) was 56% and 54%, respectively, and previous fragility fractures had occurred in 3%. Increasing age (odds ratio (95% confidence interval): 1.49 per 10 years (1.02-2.18), P = 0.04), excessive alcohol intake (2.34 (1.03-5.32), P = 0.04) and lower body mass index (0.92 per kg/m2 (0.87-0.98), P = 0.009) were independent risk factors for HO. CONCLUSION There is a high prevalence of HO and vitamin D deficiency in patients with cirrhosis at presentation irrespective of disease severity or underlying aetiology.
