Abstract
INTRODUCTION In liver cirrhosis, acute variceal bleeding (AVB) is associated with a 1-year mortality rate of up to 40%. Data on early or pre-emptive transjugular intrahepatic portosystemic stent-shunt (TIPSS) in AVB is inconclusive and may not reflect current management strategies. Randomised controlled trial of EArly transjugular intrahepatiC porTosystemic stent-shunt in AVB (REACT-AVB) aims to investigate the clinical and cost-effectiveness of early TIPSS in patients with cirrhosis and AVB after initial bleeding control. METHODS AND ANALYSIS REACT-AVB is a multicentre, randomised controlled, open-label, superiority, two-arm, parallel-group trial with an internal pilot. The two interventions allocated randomly 1:1 are early TIPSS within 4 days of diagnostic endoscopy or secondary prophylaxis with endoscopic therapy in combination with non-selective beta blockers. Patients aged ≥18 years with cirrhosis and Child-Pugh Score 7-13 presenting with AVB with endoscopic haemostasis are eligible for inclusion. The primary outcome is transplant-free survival at 1 year post randomisation. Secondary endpoints include transplant-free survival at 6 weeks, rebleeding, serious adverse events, other complications of cirrhosis, Child-Pugh and Model For End-Stage Liver Disease (MELD) scores at 6 and 12 months, health-related quality of life, use of healthcare resources, cost-effectiveness and use of cross-over therapies. The sample size is 294 patients over a 4-year recruitment period, across 30 hospitals in the UK. ETHICS AND DISSEMINATION Research ethics committee of National Health Service has approved REACT-AVB (reference number: 23/WM/0085). The results will be submitted for publication in a peer-reviewed journal. A lay summary will also be emailed or posted to participants before publication. TRIAL REGISTRATION NUMBER ISRCTN85274829; protocol version 3.0, 1 July 2023.

Abstract
BACKGROUND AND AIMS Gastric varices (GV) are reported in up to 20% of patients with portal hypertension, and bleeding is often more severe and challenging than oesophageal variceal bleeding. There is limited data on prophylaxis of GV bleeding or management in the acute setting, and different techniques are utilised. This study aims to evaluate outcomes following endoscopic ultrasound (EUS) guided placement of coils in combination with thrombin to manage GV. METHODS We retrospectively reviewed all patients treated with combination EUS-guided therapy with coils and thrombin between October 2015 and February 2020. RESULTS 20 patients underwent 33 procedures for GV therapy; 16/20 (80%) were type 1 Isolated GV (IGV1), and the remainder were type 2 Gastroesophageal Varices (GOV2). Median follow-up was 842 days (Interquartile range (IQR) 483-961). 17/20 (85%) had underlying cirrhosis, the most common aetiologies being alcohol-related liver disease and non-alcoholic steatohepatitis (NASH). The median Child-Pugh (CP) score was 6 (IQR 5-7). In 11/20 (55%) cases, the indication was secondary prophylaxis to prevent rebleeding; in 2/20 (10%), the bleeding was acute. Technical success was achieved in 19/20 (95%) of cases. During follow-up, the obliteration of flow within the varices was achieved in 17/20 (85%) cases. The 6-week survival was 100%, and 2 adverse events were reported: cases of rebleeding at day 5 and day 37; both rebleeds were successfully managed endoscopically. CONCLUSIONS EUS-guided GV obliteration combining coil placement with thrombin, in our experience, is technically safe with good medium-term efficacy. A multicenter randomised controlled trial comparing different treatment strategies would be desirable to understand options better.

Abstract
BACKGROUND & AIMS Non-selective β-blockers (NSBBs) and endoscopic variceal-ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated and decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the efficacy of NSBBs vs EVL on survival in patients with high-risk varices without previous bleeding, stratifying risk according to compensated/decompensated stage of cirrhosis. METHODS By systematic review, we identified RCTs comparing NSBBs vs EVL, in monotherapy or combined, for primary bleeding prevention. We performed a competing-risk, time-to-event meta-analysis, using individual patient data (IPD) obtained from principal investigators of RCTs. Analyses were stratified according to previous decompensation of cirrhosis. RESULTS Of 25 RCTs eligible, 14 failed to provide IPD and 11 were included, comprising 1400 patients (656 compensated, 744 decompensated), treated with NSBBs (N = 625), EVL (N = 546) or NSBB+EVL (N = 229). Baseline characteristics were similar between groups. Overall, mortality risk was similar with EVL vs. NSBBs (subdistribution hazard-ratio (sHR) = 1.05, 95% CI = 0.75-1.49) and with EVL + NSBBs vs either monotherapy, with low heterogeneity (I2 = 28.7%). In compensated patients, mortality risk was higher with EVL vs NSBBs (sHR = 1.76, 95% CI = 1.11-2.77) and not significantly lower with NSBBs+EVL vs NSBBs, without heterogeneity (I2 = 0%). In decompensated patients, mortality risk was similar with EVL vs. NSBBs and with NSBBs+EVL vs. either monotherapy. CONCLUSIONS In patients with compensated cirrhosis and high-risk varices on primary prophylaxis, NSBBs significantly improved survival vs EVL, with no additional benefit noted adding EVL to NSBBs. In decompensated patients, survival was similar with both therapies. The study suggests that NSBBs are preferable when advising preventive therapy in compensated patients.

Abstract
Ectopic variceal bleeding is a rare cause of gastrointestinal bleeding that can occur in settings of cirrhotic and non-cirrhotic portal hypertension and is characterised by its development at locations remote from the oesophagus and stomach. Ectopic varices can be difficult to identify and access, and, although a relatively uncommon cause of portal hypertensive bleeding, can represent a difficult diagnostic and therapeutic challenge associated with considerable mortality. Low incidence and variance in variceal anatomy preclude large randomised controlled trials, and clinical practice is based on experience from case reports, case series, and specialist centre expertise. Optimisation of survival outcomes relies on understanding a patient's portal venous anatomy and functional hepatic reserve to guide timely and targeted endoscopic and endovascular interventions to facilitate the rapid control of ectopic variceal bleeding.

Abstract
BACKGROUND AND AIMS Beta-blockers have been studied for the prevention of variceal bleeding and, more recently, for the prevention of all-cause decompensation. Some uncertainties regarding the benefit of beta-blockers for the prevention of decompensation remain. Bayesian analyses enhance the interpretation of trials. The purpose of this study was to provide clinically meaningful estimates of both the probability and magnitude of the benefit of beta-blocker treatment across a range of patient types. APPROACH AND RESULTS We undertook a Bayesian reanalysis of PREDESCI incorporating 3 priors (moderate neutral, moderate optimistic, and weak pessimistic). The probability of clinical benefit was assessed considering the prevention of all-cause decompensation. Microsimulation analyses were done to determine the magnitude of the benefit. In the Bayesian analysis, the probability that beta-blockers reduce all-cause decompensation was >0.93 for all priors. The Bayesian posterior hazard ratios (HR) for decompensation ranged from 0.50 (optimistic prior, 95% credible interval 0.27-0.93) to 0.70 (neutral prior, 95% credible interval 0.44-1.12). Exploring the benefit of treatment using microsimulation highlights substantial treatment benefits. For the neutral prior derived posterior HR and a 5% annual incidence of decompensation, at 10 years, an average of 497 decompensation-free years per 1000 patients were gained with treatment. In contrast, at 10 years 1639 years per 1000 patients were gained from the optimistic prior derived posterior HR and a 10% incidence of decompensation. CONCLUSIONS Beta-blocker treatment is associated with a high probability of clinical benefit. This likely translates to a substantial gain in decompensation-free life years at the population level.

Abstract
BACKGROUND AND AIMS Bleeding from parastomal varices causes significant morbidity and mortality. Treatment options are limited, particularly in high-risk patients with significant underlying liver disease and other comorbidities. The use of EUS-guided embolisation coils combined with thrombin injection in gastric varices has been shown to be safe and effective. Our institution has applied the same technique to the treatment of parastomal varices. METHODS A retrospective review was performed of 37 procedures on 24 patients to assess efficacy and safety of EUS-guided injection of thrombin, with or without embolisation coils for treatment of bleeding parastomal varices. All patients had been discussed in a multidisciplinary team meeting, and correction of portal hypertension was deemed to be contraindicated. Rebleeding was defined as stomal bleeding that required hospital admission or transfusion. RESULTS All patients had significant parastomal bleeding at the time of referral. 100% technical success rate was achieved. 70.8% of patients had no further significant bleeding in the follow-up period (median 26.2 months) following one procedure. 1-year rebleed-free survival was 80.8% following first procedure. 7 patients (29.1%) had repeat procedures. There was no significant difference in rebleed-free survival following repeat procedures. Higher age was associated with higher risk of rebleeding. No major procedure-related complications were identified. CONCLUSIONS EUS-guided thrombin injection, with or without embolisation coils, is a safe and effective technique for the treatment of bleeding parastomal varices, particularly for patients for whom correction of portal venous hypertension is contraindicated.

Abstract
The prevalence of cirrhosis has risen significantly over recent decades and is predicted to rise further. Widespread use of non-invasive testing means cirrhosis is increasingly diagnosed at an earlier stage. Despite this, there are significant variations in outcomes in patients with cirrhosis across the UK, and patients in areas with higher levels of deprivation are more likely to die from their liver disease. This three-part best practice guidance aims to address outpatient management of cirrhosis, in order to standardise care and to reduce the risk of progression, decompensation and mortality from liver disease. Part 1 addresses outpatient management of compensated cirrhosis: screening for hepatocellular cancer, varices and osteoporosis, vaccination and lifestyle measures. Part 2 concentrates on outpatient management of decompensated disease including management of ascites, encephalopathy, varices, nutrition as well as liver transplantation and palliative care. In this, the third part of the guidance, we focus on special circumstances encountered in managing people with cirrhosis, namely surgery, pregnancy, travel, managing bleeding risk for invasive procedures and portal vein thrombosis.

Abstract
There are two distinct phases in the natural history of cirrhosis: compensated disease (corresponding to Child Pugh A and early Child Pugh B disease), where the patient may be largely asymptomatic, progressing with increasing portal hypertension and liver dysfunction to decompensated disease (corresponding to Child Pugh late B-C), characterised by the development of overt clinical signs, including jaundice, hepatic encephalopathy (HE), ascites, renal dysfunction and variceal bleeding. The transition from compensated cirrhosis to decompensated cirrhosis (DC) heralds a watershed in the nature and prognosis of the disease. DC is a systemic disease, characterised by multiorgan/system dysfunction, including haemodynamic and immune dysfunction. In this second part of our three-part series on the outpatient management of cirrhosis, we address outpatient management of DC, including management of varices, ascites, HE, nutrition, liver transplantation and palliative care. We also introduce an outpatient DC care bundle. For recommendations on screening for osteoporosis, hepatocellular carcinoma surveillance and vaccination see part one of the guidance. Part 3 of the guidance focusses on special circumstances encountered in patients with cirrhosis, including surgery, pregnancy, travel, management of bleeding risk for invasive procedures and portal vein thrombosis.

Abstract
Modern smart coating systems are increasingly exploiting functional materials which combine multiple features including rheology, electromagnetic properties and nanotechnological capabilities and provide a range of advantages in diverse operations including medical, energy and transport designs (aerospace, marine, automotive). The simulation of the industrial synthesis of these multi-faceted coatings (including stagnation flow deposition processes) requires advanced mathematical models which can address multiple effects simultaneously. Inspired by these requests, this study investigates the interconnected magnetohydrodynamic non-Newtonian movement and thermal transfer in the Hiemenz plane's stagnation flow. Additionally, it explores the application of a transverse static magnetic field to a ternary hybrid nanofluid coating through theoretical and numerical analysis. The base fluid (polymeric) considered is engine-oil (EO) doped with graphene [Formula: see text], gold [Formula: see text] and Cobalt oxide [Formula: see text] nanoparticles. The model includes the integration of non-linear radiation, heat source, convective wall heating, and magnetic induction effects. For non-Newtonian characteristics, the Williamson model is utilized, while the Rosseland diffusion flux model is used for radiative transfer. Additionally, a non-Fourier Cattaneo-Christov heat flux model is utilized to include thermal relaxation effects. The governing partial differential conservation equations for mass, momentum, energy and magnetic induction are rendered into a system of coupled self-similar and non-linear ordinary differential equations (ODEs) with boundary restrictions using appropriate scaling transformations. The dimensionless boundary value problem that arises is solved using the bvp4c built-in function in MATLAB software, which employs the fourth-order Runge-Kutta (RK-4) method. An extensive examination is conducted to evaluate the impact of essential control parameters on the velocity [Formula: see text], induced magnetic field stream function gradient [Formula: see text] and temperature [Formula: see text] is conducted. The relative performance of ternary, hybrid binary and unitary nanofluids for all transport characteristics is evaluated. The inclusion of verification of the MATLAB solutions with prior studies is incorporated. Fluid velocity is observed to be minimized for the ternary [Formula: see text]-[Formula: see text]-[Formula: see text] nanofluid whereas the velocity is maximized for the unitary cobalt oxide [Formula: see text] nanofluid with increasing magnetic parameter ([Formula: see text] Temperatures are elevated with increment in thermal radiation parameter (Rd). Streamlines are strongly modified in local regions with greater viscoelasticity i.e. higher Weissenberg number [Formula: see text]. Dimensionless skin friction is significantly greater for the ternary hybrid [Formula: see text]-[Formula: see text]-[Formula: see text] nanofluid compared with binary hybrid or unitary nanofluid cases.

Abstract
BACKGROUND Porto-sinusoidal vascular liver disorder (PSVD) is a rare disease that occasionally requires liver transplantation (LT), despite usually presenting preserved liver function. There remains a paucity of data pertaining to LT in PSVD. The aim was to identify features associated with post-LT outcomes in PSVD. METHODS Retrospective multicentre study of 79 patients who received LT for PSVD. RESULTS Median post-LT follow-up was 37 (range 1-261) mo. Refractory ascites 24 (30%), hepatic encephalopathy 16 (20%), and hepatopulmonary syndrome 13 (16.3%) were the most frequent indications for LT. Hepatocellular carcinoma was the indication in only 2 patients. Twenty-four patients died, 7 due to liver and 17 to non-liver related causes. Post-LT survival was 82.2%, 80.7%, and 68.6% at 1, 2, and 5 y, respectively. Post-LT survival was significantly better in patients without (n = 58) than in those with a persistent severe PSVD-associated condition (n = 21). Pre-LT hyperbilirubinemia levels and creatinine >100 µmol/L were also independently associated with poor survival. Six patients (7.6%) required a second LT. Recurrence of PSVD was confirmed by liver biopsy in only 1 patient and in 3 further patients it was likely. CONCLUSIONS LT in PSVD is associated with an acceptable outcome in the absence of associated severe conditions. However, persistence of a severe associated condition, pre-LT high bilirubin levels, or creatinine >100 µmol/L impact outcome, and these are features that should be considered when evaluating PSVD patients for LT. PSVD recurrence is possible after LT and needs to be explored, at least, in cases of posttransplant portal hypertension.

Abstract
BACKGROUND AND OBJECTIVES Blood-borne pathogens are contagious microorganisms that can cause life-threatening illnesses, and are found in human blood. It is crucial to examine how these viruses spread through blood flow in the blood vessel. Keeping that in view, this study aims to determine how blood viscosity, and diameter of the viruses can affect the virus transmission through the blood flow in the blood vessel. A comparative study of bloodborne viruses (BBVs) such as HIV, Hepatitis B, and C, has been addressed in the present model. A couple stress fluid model is used to represent blood as a carrying medium for virus transmission. The Basset-Boussinesq-Oseen equation is taken into account for the simulation of virus transmission. METHODS An analytical approach to derive the exact solutions under the assumption of long wavelength and low Reynolds number approximations is employed. For the computation of the results, a segment (wavelength) of blood vessels about 120 mm with wave velocities in the range of 49 - 190 mm/sec are considered, where the diameter of BBVs ranges from 40-120 nm. The viscosity of the blood varies from 3.5-5.5 × 10-3Ns/m2 which affect the virion motion having a density range 1.03 - 1. 25 g/m3. RESULTS It shows that the Hepatitis B virus is more harmful than other blood-borne viruses considered in the analysis. Patients with high blood pressure are highly susceptible for transmission of BBVs. CONCLUSIONS The present fluid dynamics approach for virus spread through blood flow can be helpful in understanding the dynamics of virus propagation inside the human circulatory system.

Abstract
As a result of the increasing incidence of cirrhosis in the UK, more patients with chronic liver disease are being considered for elective non-hepatic surgery. A historical reluctance to offer surgery to such patients stems from general perceptions of poor postoperative outcomes. While this is true for those with decompensated cirrhosis, selected patients with compensated early-stage cirrhosis can have good outcomes after careful risk assessment. Well-recognised risks include those of general anaesthesia, bleeding, infections, impaired wound healing, acute kidney injury and cardiovascular compromise. Intra-abdominal or cardiothoracic surgery are particularly high-risk interventions. Clinical assessment supplemented by blood tests, imaging, liver stiffness measurement, endoscopy and assessment of portal pressure (derived from the hepatic venous pressure gradient) can facilitate risk stratification. Traditional prognostic scoring systems including the Child-Turcotte-Pugh and Model for End-stage Liver Disease are helpful but may overestimate surgical risk. Specific prognostic scores like Mayo Risk Score, VOCAL-Penn and ADOPT-LC can add precision to risk assessment. Measures to mitigate risk include careful management of varices, nutritional optimisation and where possible addressing any ongoing aetiological drivers such as alcohol consumption. The role of portal decompression such as transjugular intrahepatic portosystemic shunting can be considered in selected high-risk patients, but further prospective study of this approach is required. It is of paramount importance that patients are discussed in a multidisciplinary forum, and that patients are carefully counselled about potential risks and benefits.

Abstract
INTRODUCTION Patients with liver disease and portal hypertension frequently require surgery carrying high morbidity and mortality. Accurately estimating surgical risk remains challenging despite improved medical and surgical management. AREAS COVERED This review aims to outline a comprehensive approach to preoperative assessment, appraise methods used to predict surgical risk, and provide an up-to-date overview of outcomes for patients with cirrhosis undergoing non-hepatic surgery. EXPERT OPINION Robust preoperative, individually tailored, and precise risk assessment can reduce peri- and postoperative complications in patients with cirrhosis. Established prognostic scores aid stratification, providing an estimation of postoperative mortality, albeit with limitations. VOCAL-Penn Risk Score may provide greater precision than established liver severity scores. Amelioration of portal hypertension in advance of surgery may be considered, with prospective data demonstrating hepatic venous pressure gradient as a promising surrogate marker of postoperative outcomes. Morbidity and mortality vary between types of surgery with further studies required in patients with more advanced liver disease. Patient-specific considerations and practicing precision medicine may allow for improved postoperative outcomes.

Abstract
BACKGROUND Pre-emptive transjugular intrahepatic portosystemic shunt (pTIPSS) should be considered within 72 hours following acute oesophageal variceal bleeding. However, recent studies highlight the difficulty in providing pTIPSS within this narrow timeframe. Delaying pTIPSS beyond 72 hours has not been studied. AIM To determine if the time taken to perform pTIPSS alters patient outcome. METHOD Patients referred to 4 UK tertiary centres for pTIPSS between 01 January 2010 and 31 December 2018 were included. Time from endoscopy to pTIPSS was recorded and pre-defined clinically relevant outcomes were observed relative to two groups: early pTIPSS (<72 h) and late pTIPSS (72 h-28 days). The primary outcome was transplant-free survival at 1-year. Follow-up was until 31 December 2020. RESULTS A total of 83 patients received early pTIPSS and 88 received late pTIPSS. Baseline characteristics were similar with no requirement for propensity score-matched analysis. There was no difference between early and late pTIPSS groups for patient outcomes; 1-year transplant-free survival rate (69.9% vs 71.6%, p = 0.73, HR 0.91, 95% CI 0.52-1.58), long-term survival (p = 0.52, HR 1.132, 95% CI 0.77-1.65), variceal rebleeding (4.82% vs 11.36%, p = 0.09, HR 0.411, 95% CI 0.14-1.17), hepatic encephalopathy (43.93% vs 34.61%, p = 0.26) and new or worsening ascites (16.6% vs 13.46%, p = 0.79). Death due to liver failure was significantly more prevalent in those undergoing early pTIPSS compared to late pTIPSS (44% vs 16%, p = 0.046, HR 2.79, 95%CI 1.02-8.32). CONCLUSION Placement of pTIPSS within 72 hours offered similar short- and long-term survival benefits compared to pTIPSS placed between 72 hours and 28 days. Early pTIPSS may be associated with an increased risk of liver failure-related mortality. Further large, randomised studies are required to evaluate these findings.

Abstract
BACKGROUND Refractory ascites has a 1-year survival rate of 50%. In selected patients, treatment options include liver transplantation (LT) or transjugular intrahepatic portosystemic stent shunt (TIPSS).
AIM To assess the outcomes of patients who underwent a TIPSS compared to large volume paracentesis (LVP).
METHODS Retrospective study of patients who underwent a covered TIPSS or LVP for refractory or recurrent ascites over 7 years. Primary outcome was transplant-free survival (TFS). Further analysis was done with propensity score matching (PSM).
RESULTS There were 150 patients [TIPSS group (n = 75), LVP group (n = 75)]. Seven patients in the TIPSS group underwent LT vs 22 patients in the LVP group. Overall median follow up, 20 (0.47-179.53) mo. In the whole cohort, there was no difference in TFS [hazard ratio (HR): 0.80, 95% confidence interval (CI): 0.54-1.21]; but lower de novo hepatic encephalopathy with LVP (HR: 95%CI: 0.20-0.96). These findings were confirmed following PSM analysis. On multivariate analysis albumin and hepatocellular carcinoma at baseline were associated with TFS.
CONCLUSION Covered TIPSS results in similar TFS compared to LVP in cirrhotic patients with advanced liver failure. Liver transplant assessment should be considered in all potential candidates for TIPSS. Further controlled studies are recommended to select appropriate patients for TIPSS.

Abstract
BACKGROUND & AIMS Whether non-selective β-blockers can prevent decompensation of cirrhosis warrants clarification. Carvedilol might be particularly effective since its intrinsic vasodilatory activity may ameliorate hepatic vascular resistance, a major mechanism of portal hypertension in early cirrhosis. We assessed whether carvedilol may prevent decompensation and improve survival in patients with compensated cirrhosis and clinically significant portal hypertension (CSPH). METHODS By systematic review we identified randomized-controlled trials (RCTs) comparing carvedilol vs. control therapy (no-active treatment or endoscopic variceal ligation [EVL]) in patients with cirrhosis and CSPH without previous bleeding. We performed a competing-risk time-to-event meta-analysis using individual patient data (IPD) obtained from principal investigators of RCTs. Only compensated patients were included. Primary outcomes were prevention of decompensation (liver transplantation and death were competing events) and death (liver transplantation was a competing event). Models were adjusted using propensity scores for baseline covariates with the inverse probability of treatment weighting (IPTW) approach. RESULTS Among 125 full-text studies evaluated, 4 RCTs were eligible. The 4 provided IPD and were included, comprising 352 patients with compensated cirrhosis, 181 treated with carvedilol and 171 controls (79 received EVL and 92 placebo). Baseline characteristics were similar between groups. Standardized differences were <10% by IPTW. The risk of developing decompensation of cirrhosis was lower with carvedilol than in controls (subdistribution hazard ratio [SHR] 0.506; 95% CI 0.289-0.887; p = 0.017; I2 = 0.0%, Q-statistic-p = 0.880), mainly due to a reduced risk of ascites (SHR 0.491; 95% CI 0.247-0.974; p = 0.042; I2 = 0.0%, Q-statistic-p = 0.384). The risk of death was also lower with carvedilol (SHR 0.417; 95% CI 0.194-0.896; p = 0.025; I2 = 0.0%, Q-statistic-p = 0.989). CONCLUSIONS Long-term carvedilol therapy reduced decompensation of cirrhosis and significantly improved survival in compensated patients with CSPH. This suggests that screening patients with compensated cirrhosis for CSPH to enable the prompt initiation of carvedilol could improve outcomes. PROSPERO REGISTRATION NUMBER CRD42019144786. LAY SUMMARY The transition from compensated cirrhosis to decompensated cirrhosis is associated with markedly reduced life expectancy. Therefore, preventing decompensation in patients with compensated cirrhosis would be associated with greatly improved patient outcomes. There has been controversy regarding the use of non-selective β-blockers (portal pressure-lowering medications) in patients with cirrhosis and elevated portal blood pressure (portal hypertension). Herein, using a competing-risk meta-analysis to optimize sample size and properly investigate cirrhosis as a multistate disease and outcomes as time-dependent events, we show that carvedilol (a non-selective β-blocker) is associated with a reduced risk of decompensating events and improved survival in patients with cirrhosis and portal hypertension.

Abstract
BACKGROUND AND AIMS Carvedilol reduces rates of variceal bleeding and rebleeding by lowering portal pressure. However, an associated pleiotropic survival benefit has been proposed. We aimed to assess long-term survival in a cohort of patients previously randomised to receive either carvedilol or endoscopic band ligation (EBL) following oesophageal variceal bleeding (OVB). METHODS The index study randomised 64 cirrhotic patients with OVB between 2006 and 2011 to receive either carvedilol or EBL. Follow-up was undertaken to April 2020 by review of electronic patient records. The primary outcome was survival. Other outcomes including variceal rebleeding and liver decompensation events were compared. RESULTS 26 out of 33 participants received carvedilol in the follow-up period and 28 out of 31 attended regular EBL sessions. The median number of follow-up days for all patients recruited was 1459 (SE = 281.74). On the intention to treat analysis, there was a trend towards improved survival in the carvedilol group (p = 0.09). On per-protocol analysis, carvedilol use was associated with improved long-term survival (p = 0.005, HR 3.083, 95% CI 1.397-6.809), fewer liver-related deaths (0% vs 22.57%, p = 0.013, OR ∞, 95%CI 1.565-∞) and fewer admissions with decompensated liver disease (12% vs 64.29%, p = 0.0002, OR 13.2, 95% CI 3.026-47.23) compared to the EBL group. There was no statistically significant difference in variceal rebleeding rates. CONCLUSION Following OVB in cirrhotic patients, carvedilol use is associated with survival benefit, fewer liver-related deaths and fewer hospital admissions with decompensated liver disease. Further studies are needed to validate this finding.

Abstract
OBJECTIVE The aim of the study was to show the effect that two naturally occurring compounds, a cyclodextrin and hydroxytyrosol, can have on the entry of SARS-CoV-2 into human cells. MATERIALS AND METHODS The PubMed database was searched to retrieve studies published from 2000 to 2020, satisfying the inclusion criteria. The search keywords were: SARS-CoV, SARS-CoV-2, coronavirus, lipid raft, endocytosis, hydroxytyrosol, cyclodextrin. Modeling of alpha-cyclodextrin and hydroxytyrosol were done using UCSF Chimera 1.14. RESULTS The search results indicated that cyclodextrins can reduce the efficiency of viral endocytosis and that hydroxytyrosol has antiviral properties. Bioinformatic docking studies showed that alpha-cyclodextrin and hydroxytyrosol, alone or in combination, interact with the viral spike protein and its host cell receptor ACE2, thereby potentially influencing the endocytosis process. CONCLUSIONS Hydroxytyrosol and alpha-cyclodextrin can be useful against the spread of SARS-CoV-2.

Abstract
Variceal bleeding is a serious complication of cirrhosis and portal hypertension. Despite the improvement in management of acute variceal bleed (AVB), it still carries significant mortality. Portal pressure is the main driver of variceal bleeding and also a main predictor of decompensation. Reduction in portal pressure has been the mainstay of management of variceal bleeding. Transjugular intrahepatic porto-systemic stent shunt (TIPSS) is a very effective modality in reducing the portal hypertension and thereby, controlling portal hypertensive bleeding. However, its use in refractory bleeding (rescue/salvage TIPSS) is still associated with high mortality. “Early” use of TIPSS as a “pre-emptive strategy” in patients with AVB at high risk of failure of treatment has shown to be superior to standard treatment in several studies. While patients with Child C cirrhosis (up to 13 points) clearly benefit from early-TIPSS strategy, it’s role in less severe liver disease (Child B) and more severe disease (Child C > 13 points) remains less clear. Moreover, standard of care has improved in the last decade leading to improved 1-year survival in high-risk patients with AVB as compared to earlier “early” TIPSS studies. Lastly in the real world, only a minority of patients with AVB fulfil the stringent criteria for early TIPSS. Therefore, there is unmet need to explore role of early TIPSS in management of AVB in well-designed prospective studies. In this review, we have appraised the role of early TIPSS, patient selection and discussed future directions in the management of patients with AVB.

Abstract
Objectives Transjugular intrahepatic portosystemic stent shunt (TIPSS) is clinically effective in variceal bleeding and refractory ascites; however, the cost-effectiveness of TIPSS has yet to be evaluated in the UK. This study aimed to establish the cost-effectiveness of (i) pre-emptive TIPSS versus endoscopic band ligation (EBL) in populations with variceal bleeding and (ii) TIPSS versus large volume paracentesis (LVP) in refractory ascites. Methods A cost-utility analysis was conducted with the perspective including healthcare costs and quality-adjusted life years (QALYs). A Markov model was constructed with a 2-year time horizon, health states for mortality and survival and probabilities for the development of variceal bleeding, ascites and hepatic encephalopathy. A survival analysis was conducted to extrapolate 12-month to 24-month mortality for the refractory ascites indication. Uncertainty was analysed in deterministic and probabilistic sensitivity analyses. Results TIPSS was cost-effective (dominant) and cost saving for both indications. For variceal bleeding, pre-emptive TIPSS resulted in 0.209 additional QALYs, and saved £600 per patient compared with EBL. TIPSS had a very high probability of being cost-effective (95%) but was not cost saving in scenario analyses driven by rates of variceal rebleeding. For refractory ascites, TIPSS resulted in 0.526 additional QALYs and saved £17 983 per patient and had a 100% probability of being cost-effective and cost saving when compared with LVP. Conclusions TIPSS is a cost-effective intervention for variceal bleeding and refractory ascites. TIPSS is highly cost-saving for refractory ascites. Robust randomised trial data are required to confirm whether pre-emptive TIPSS is cost saving for variceal bleeding.

Abstract
Background The most common fatal complication of liver cirrhosis is haemorrhaging caused by variceal rupture. The prevention of the first variceal bleed is, therefore, an important clinical goal. Little is known about patients’ experience of treatments geared towards this, or of their perceptions of treatments prior to being exposed to them. Aims To explore the factors impacting patient preference for, and actual experience of carvedilol and variceal band ligation. Methods Semistructured interviews were conducted with 30 patients from across the UK at baseline, prior to random allocation to either carvedilol or variceal band ligation. Twenty patients were interviewed a second time at 6-month follow-up. Five patients who declined the trial were also interviewed. Data were analysed using thematic analysis. Results There was no clear preference for either treatment pathway at baseline. Key factors reported by patients to influence their treatment preference included: negative experiences with key treatment processes; how long-term or short-term treatment was perceived to be; treatment misconceptions; concerns around polypharmacy and worries around treatment adherence. Patient treatment experience was influenced by their perceptions of treatment effectiveness; clinical surveillance; clinician interaction and communication, or lack thereof. Carvedilol-specific experience was also influenced by the manifestation of side effects and patient dosage routine. Variceal band ligation-specific experience was positively influenced by the use of sedation, and negatively influenced by the procedure recovery period. Conclusions These data do not support a view that the patient experience of beta-blockade for prevention of variceal bleeds is likely to be superior to variceal band ligation.

Abstract
BACKGROUND Primary prophylaxis of variceal haemorrhage with non-selective beta blockers (NSBB) or variceal band ligation (VBL) is now standard of care in patients with cirrhosis with portal hypertension. NSBB, and particularly carvedilol, may be associated with improved survival. AIM To assess mortality in a cohort of patients previously randomised to either carvedilol or VBL. METHODS We retrospectively analysed 152 patients recruited to a multi-centre randomised controlled trial between 7 April 2000 and 24 June 2006 designed to assess the efficacy of VBL versus carvedilol in preventing first variceal bleed. We used electronic records to undertake long-term follow-up (up to 20 years) with the primary outcome of all-cause mortality and secondary end points of liver-related mortality and decompensation events (ascites, encephalopathy, variceal bleeding). RESULTS We included 152 patients in analysis with baseline characteristics well matched between the carvedilol (n = 77) and VBL (n = 75) groups. In the intention-to-treat analysis, carvedilol offered a significant survival advantage with median survival of 7.8 years compared to 4.2 years in the VBL group (P = 0.03). This survival benefit was maintained in per-protocol analysis when patients who crossed between treatment arms were excluded (P = 0.02). Transplant-free survival, liver-related mortality and decompensation events were similar in both groups. CONCLUSION These data suggest that carvedilol offers a significant survival benefit for patients with cirrhosis and portal hypertension. The difference in all-cause and liver-related mortality suggests that this survival benefit may not be entirely liver-related. Prospective, studies are required to confirm these important findings.

Abstract
These guidelines on transjugular intrahepatic portosystemic stent-shunt (TIPSS) in the management of portal hypertension have been commissioned by the Clinical Services and Standards Committee (CSSC) of the British Society of Gastroenterology (BSG) under the auspices of the Liver Section of the BSG. The guidelines are new and have been produced in collaboration with the British Society of Interventional Radiology (BSIR) and British Association of the Study of the Liver (BASL). The guidelines development group comprises elected members of the BSG Liver Section, representation from BASL, a nursing representative and two patient representatives. The quality of evidence and grading of recommendations was appraised using the GRADE system. These guidelines are aimed at healthcare professionals considering referring a patient for a TIPSS. They comprise the following subheadings: indications; patient selection; procedural details; complications; and research agenda. They are not designed to address: the management of the underlying liver disease; the role of TIPSS in children; or complex technical and procedural aspects of TIPSS.

Abstract
The study of heat and electroosmotic characteristics in the flow of a third-order fluid regulated by peristaltic pumping is examined by using governing equations, i.e., the continuity equation, momentum equation, energy equation, and concentration equation. The wavelength is considered long compared to its height and a low Reynolds number is assumed. The velocity slip condition is employed. Analytical solutions are performed through the perturbation technique. The expressions for the dimensionless velocity components, temperature, concentration, and heat transfer rate are obtained. Pumping features were computed numerically for discussion of results. Trapping and heat transfer coefficient distributions were also studied graphically. The findings of the present study can be applied to design biomicrofluidic devices like tumor-on-a-chip and organ-on-a-chip.

Abstract
Survival rates for patients following liver transplantation exceed 90% at 12 months and approach 70% at 10 years. Part 1 of this guideline has dealt with all aspects of liver transplantation up to the point of placement on the waiting list. Part 2 explains the organ allocation process, organ donation and organ type and how this influences the choice of recipient. After organ allocation, the transplant surgery and the critical early post-operative period are, of necessity, confined to the liver transplant unit. However, patients will eventually return to their referring secondary care centre with a requirement for ongoing supervision. Part 2 of this guideline concerns three key areas of post liver transplantation care for the non-transplant specialist: (1) overseeing immunosuppression, including interactions and adherence; (2) the transplanted organ and how to initiate investigation of organ dysfunction; and (3) careful oversight of other organ systems, including optimising renal function, cardiovascular health and the psychosocial impact. The crucial significance of this holistic approach becomes more obvious as time passes from the transplant, when patients should expect the responsibility for managing the increasing number of non-liver consequences to lie with primary and secondary care.

Abstract
Liver transplantation is a highly successful treatment for all types of liver failure, some non-liver failure indications and liver cancer. Most referrals come from secondary care. This first part of a two-part guideline outlines who to refer, and how that referral should be made, including patient details and additional issues such as those relevant to alcohol and drug misuse. The process of liver transplant assessment involves the confirmation of the diagnosis and non-reversibility, an evaluation of comorbidities and exclusion of contraindications. Finally, those making it onto the waiting list require monitoring and optimising. Underpinning this process is a need for good communication between patient, their carers, secondary care and the liver transplant service, synchronised by the transplant coordinator. Managing expectation and balancing the uncertainty of organ availability against the inevitable progression of underlying liver disease requires sensitivity and honesty from all healthcare providers and the assessment of palliative care needs is an integral part of this process.

Abstract
Congenital extrahepatic portosystemic shunt (CEPS) or Abernethy malformation is a rare condition in which splanchnic venous blood bypasses the liver draining directly into systemic circulation through a congenital shunt. Patients may develop hepatic encephalopathy (HE), pulmonary hypertension (PaHT), or liver tumors, among other complications. However, the actual incidence of such complications is unknown, mainly because of the lack of a protocolized approach to these patients. This study characterizes the clinical manifestations and outcome of a large cohort of CEPS patients with the aim of proposing a guide for their management. This is an observational, multicenter, international study. Sixty-six patients were included; median age at the end of follow-up was 30 years. Nineteen patients (28%) presented HE. Ten-, 20-, and 30-year HE incidence rates were 13%, 24%, and 28%, respectively. No clinical factors predicted HE. Twenty-five patients had benign nodular lesions. Ten patients developed adenomas (median age, 18 years), and another 8 developed HCC (median age, 39 years). Of 10 patients with dyspnea, PaHT was diagnosed in 8 and hepatopulmonary syndrome in 2. Pulmonary complications were only screened for in 19 asymptomatic patients, and PaHT was identified in 2. Six patients underwent liver transplantation for hepatocellular carcinoma or adenoma. Shunt closure was performed in 15 patients with improvement/stability/cure of CEPS manifestations. Conclusion: CEPS patients may develop severe complications. Screening for asymptomatic complications and close surveillance is needed. Shunt closure should be considered both as a therapeutic and prophylactic approach.

Abstract
Acute upper gastrointestinal bleed (AUGIB) is one of the most common medical emergencies in the UK, with roughly one presentation every 6 min. Despite advances in therapeutics and endoscopy provision, mortality following AUGIB over the last two decades has remained high, with over 9,000 deaths annually in the UK; consequently, several national bodies have published UK-relevant guidelines. Despite this, the 2015 UK National Confidential Enquiry into Patient Outcome and Death in AUGIB highlighted variations in practice, raised concerns regarding suboptimal patient care and released a series of recommendations. This review paper incorporates the latest available evidence and UK-relevant guidelines to summarise the optimal pre-endoscopic, endoscopic, and post-endoscopic approach to and management of non-variceal and variceal AUGIB that will be of practical value to both general physicians and gastroenterologists.

Abstract
Introduction Liver cirrhosis is the fifth largest cause of adult deaths, and a major complication, variceal bleeding is associated with a 1-year mortality of 40%. There is uncertainty on the first-line therapy for prevention of variceal bleeding owing to a lack of adequately powered trials comparing non-selective beta blockers, in particular carvedilol, with variceal band ligation. Methods and analysis CALIBRE is a multicentre, pragmatic, randomised controlled, open-label trial with an internal pilot. The two interventions are carvedilol 12.5 mg od or variceal band ligation (VBL). Patients with liver cirrhosis and medium to large oesophageal varices that have never bled are eligible for inclusion. The primary outcome is any variceal bleeding within 1 year of randomisation. Secondary endpoints include time to variceal bleed, mortality, transplant-free survival, adverse events, complications of cirrhosis, health-related quality of life, use of healthcare resources, patient preference and use of alternative or crossover therapies. The sample size is 2630 patients over a 4-year recruitment period, across 66 hospitals in the UK. Ethics and dissemination The study has been approved by a National Health Service (NHS) Research Ethics Committee (REC) (reference number 18/NE/0296). The results of this trial will be submitted for publication in a peer reviewed journal. Participants will be informed via a link to a preview of the publication. A lay summary will also be provided via email or posted to participants prior to publication (ISRCTN reference number: 73887615).

Abstract
BACKGROUND Budd-Chiari syndrome (BCS) is a rare but fatal disease caused by obstruction in the hepatic venous outflow tract. AIM To provide an update of the pathophysiology, aetiology, diagnosis, management and follow-up of BCS. METHODS Analysis of recent literature by using Medline, PubMed and EMBASE databases. RESULTS Primary BCS is usually caused by thrombosis and is further classified into "classical BCS" type where obstruction occurs within the hepatic vein and "hepatic vena cava BCS" which involves thrombosis of the intra/suprahepatic portion of the inferior vena cava (IVC). BCS patients often have a combination of prothrombotic risk factors. Aetiology and presentation differ between Western and certain Asian countries. Myeloproliferative neoplasms are present in 35%-50% of European patients and are usually associated with the JAK2-V617F mutation. Clinical presentation is diverse and BCS should be excluded in any patient with acute or chronic liver disease. Non-invasive imaging (Doppler ultrasound, computed tomography, or magnetic resonance imaging) usually provides the diagnosis. Liver biopsy should be obtained if small vessel BCS is suspected. Stepwise management strategy includes anticoagulation, treatment of identified prothrombotic risk factors, percutaneous revascularisation and transjugular intrahepatic portosystemic stent shunt to re-establish hepatic venous drainage, and liver transplantation in unresponsive patients. This strategy provides a 5-year survival rate of nearly 90%. Long-term outcome is influenced by any underlying haematological condition and development of hepatocellular carcinoma. CONCLUSIONS With the advent of newer treatment strategies and improved understanding of BCS, outcomes in this rare disease have improved over the last three decades. An underlying haematological disorder can be the major determinant of outcome.

Abstract
BACKGROUND Cardiac dysfunction is frequently observed in patients with cirrhosis. There remains a paucity of data from routine clinical practice regarding the role of echocardiography in the pre-assessment of transjugular intrahepatic portosystemic stent-shunt. AIM Our study aimed to investigate if echocardiography parameters predict outcomes after transjugular intrahepatic portosystemic stent-shunt insertion in cirrhosis. METHODS Patients who underwent echocardiography and transjugular intrahepatic portosystemic stent-shunt insertion at the liver unit (Birmingham, UK) between 1999 and 2016 were included. All echocardiography measures (including left ventricle ejection fraction; early maximal ventricular filling/late filling velocity ratio, diastolic dysfunction as per British Society of Echocardiography guidelines) were independently reviewed by a cardiologist. Predictors of 30-day and overall transplant free-survival were assessed. RESULTS One Hundred and Seventeen patients with cirrhosis (median age 56 years; 54% alcohol; Child-Pugh B/C 71/14.5%; Model For End-Stage Liver Disease 12) underwent transjugular intrahepatic portosystemic stent-shunt for ascites (n = 78) and variceal haemorrhage (n = 39). Thirty-day and overall transplant-free survival was 90% (n = 105) and 31% (n = 36), respectively, over a median 663 (IQR 385-2368) days follow-up. Model for End-Stage Liver Disease (P < 0.001) and Child-Pugh Score (P = 0.002) significantly predicted 30-day and overall transplant-free survival. Model for End-Stage Liver Disease ≥15 implied three-fold risk of death. Six per cent (n = 7) of patients pre-transjugular intrahepatic portosystemic stent-shunt had a history of ischaemic heart disease and 34% (n = 40) had 1 or more cardiovascular disease risk factors. Fifty per cent (n = 59) had an abnormal echocardiogram and 33% (n = 39) had grade 1-3 diastolic dysfunction. On univariate analysis none of the echocardiography measures pre-intervention were related to 30-day or overall transplant-free survival post-transjugular intrahepatic portosystemic stent-shunt. CONCLUSIONS Ventricular, in particular diastolic dysfunction in patients with cirrhosis does not predict survival after transjugular intrahepatic portosystemic stent-shunt insertion. Model for End-Stage Liver Disease and Child-Pugh scores remain the best predictors of survival. Further prospective study is required to clarify the role of routine echocardiography prior to transjugular intrahepatic portosystemic stent-shunt insertion.

Abstract
BACKGROUND & AIMS A total of 15% of patients with idiopathic non-cirrhotic portal hypertension (INCPH) are women of childbearing age. We aimed to determine maternal and fetal outcome of pregnancies occurring in women with INCPH. METHODS We retrospectively analyzed the charts of women with INCPH followed in the centers of the VALDIG network, having had ≥1 pregnancy during the follow-up of their liver disease. Data are represented as median (interquartile range). RESULTS A total of 24 pregnancies occurred in 16 women within 24 (5-66) months after INCPH diagnosis. Four women had associated partial portal vein thrombosis before pregnancy. At conception, 2 out of the 16 women had detectable ascites and others were asymptomatic. Out of these 24 pregnancies, there were four miscarriages, one ectopic pregnancy, and one medical termination of pregnancy at 20 weeks of gestation. Out of the 18 other pregnancies reaching 20 weeks of gestation (in 14 patients), there were nine preterm and nine term deliveries. All infants were healthy at delivery, but one died at day 1 of unknown cause and one at day 22 of infectious meningitis; both were preterm. Concerning mothers, two had worsening of ascites, two had variceal bleeding despite non-selective betablockers during pregnancy and one developed a main portal vein thrombosis in early postpartum. Genital bleeding occurred in three patients, including two receiving anticoagulation. All 16 women were alive and asymptomatic after a median follow-up of 27 (9-93) months after last delivery. CONCLUSION The overall outcome of women with INCPH who become pregnant is favorable despite a significant incidence of complications related to portal hypertension. Fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation. LAY SUMMARY About 15% of patients with idiopathic non-cirrhotic portal hypertension are women of childbearing age, who can become pregnant. As available reports on pregnancy in these women are scarce and heterogeneous, it is unclear whether or not pregnancy should be contraindicated in this setting. We provide detailed data showing that, regardless of the associated conditions, the overall outcome of women with idiopathic non-cirrhotic portal hypertension becoming pregnant is good despite a significant incidence of complications related to portal hypertension, and that fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation.

Abstract
BACKGROUND AND AIM Acute variceal bleeding (AVB) is life-threatening. We aimed to systematically review the current evidence regarding the efficacy and safety of terlipressin for AVB in liver cirrhosis. METHODS We searched the PubMed, EMBASE, and Cochrane Library databases. The reference list was also hand-searched. Using a random-effect model, we combined the data obtained according to the different time points when the events developed. Odds ratio (OR) and weighted mean difference (WMD) were calculated. Quality of evidence was evaluated by the GRADE methodology. RESULTS Thirty randomized controlled trials with 3344 patients were included. Compared with no vasoactive drug, terlipressin significantly improved the control of bleeding within 48 hours (OR = 2.94, P = .0008) and decreased the in-hospital mortality (OR = 0.31, P = .008). Compared with somatostatin, terlipressin had a significantly higher risk of complications (OR = 2.44, P = .04). Compared with octreotide, terlipressin had a significantly inferior control of bleeding within 24 hours (OR = 0.37, P = .007). Compared with vasopressin, terlipressin had a significantly lower risk of complications (OR = 0.15, P = .02). Compared with terlipressin combined with endoscopic variceal ligation, terlipressin alone had significantly higher 5-day treatment failure (OR = 14.46, P = .01) and transfusion requirements within 49 to 120 hours (WMD = 1.20, P = .002). No outcome was significantly different between terlipressin and sclerotherapy. Compared with balloon tamponade, terlipressin significantly decreased the 30-day rebleeding (OR = 0.05, P = .001) and transfusion requirements (WMD = -2.70, P = .02). Quality of evidence was very low to moderate. CONCLUSION Our findings were in accordance with the current recommendations regarding terlipressin for the treatment of AVB in cirrhosis. However, due to low quality of evidence, further studies are recommended.

Abstract
Budd-Chiari syndrome (BCS) is a rare but fatal disease caused by the obstruction in hepatic venous outflow tract (usually by thrombosis) and is further classified into two subtypes depending on the level of obstruction. Patients with BCS often have a combination of prothrombotic risk factors. Clinical presentation is diverse. Stepwise management strategy has been suggested with excellent 5-year survival rate. It includes anticoagulation, treatment of identified prothrombotic risk factor, percutaneous recanalization, and transjugular intrahepatic portosystemic shunt (TIPS) to reestablish hepatic venous outflow and liver transplantation in unresponsive patients. Owing to the rarity of BCS, there are no randomized controlled trials (RCTs) precisely identifying the timing for TIPS. TIPS should be considered in patients with refractory ascites, variceal bleed, and fulminant liver failure. Liver replacement is indicated in patients with progressive liver failure and in those in whom TIPS is not technically possible. The long-term outcome is usually influenced by the underlying hematologic condition and the development of hepatocellular carcinoma. This review focuses on the timing and the long-term efficacy of TIPS in patients with BCS.
