Abstract
BACKGROUND/OBJECTIVES Engagement in regular physical activity is one of the best strategies for older adults to remain healthy. Unfortunately, only 35% of older adults meet guidelines for muscle strengthening activities. Eliciting participant preferences is one possible way to improve physical activity engagement. However, other sources of participant input to improve uptake and maintenance remain uninvestigated. This study compared preferences to self-efficacy ratings for two strength training programs. METHODS We conducted a national cross-sectional survey of 611 US adults over age 65. We compared two participant evaluations (the preferred program and the program for which they had higher barrier self-efficacy) of two hypothetical strength training programs (45 minutes performed three times per week (traditional) and 5 minutes performed daily (brief)). RESULTS Most participants (68%) preferred the brief strength training program. The difference in self-efficacy ratings was an average of 1.2 (SD = 0.92). One in five participants preferred a strength training program for which they had less self-efficacy; nearly all of these participants (92%) preferred the traditional strength training program but had more self-efficacy for the brief strength training program. CONCLUSION Older adults reported preferring and having more self-efficacy for a brief compared to a traditional strength training program. Differences in self-efficacy ratings between the two strength training programs were large. Preferences were often not congruent with ratings of self-efficacy. SIGNIFICANCE/IMPLICATIONS Preferences for strength training programming may not always reflect the program most likely to be maintained. Future investigations should evaluate differences in behavioral uptake, maintenance, and outcomes from two comparative strength training interventions using preferences and self-efficacy.

Abstract
BACKGROUND AND AIMS Exercise training is recommended for all patients with metabolic dysfunction-associated steatotic liver disease and may reverse liver fibrosis. Whether exercise training improves liver fibrosis without body weight loss remains controversial. We further investigated this relationship using serum biomarkers of liver fibroinflammation in a post hoc analysis of an exercise trial where patients did not lose significant body weight. METHODS In the NASHFit trial, patients with metabolic dysfunction-associated steatohepatitis were randomized to receive either moderate-intensity aerobic exercise training or standard clinical care for 20 weeks. Mediterranean-informed dietary counselling was provided to each group. Change in serum biomarkers was measured and compared between the two groups. RESULTS Exercise training led to improvement in serum biomarkers of liver fibroinflammation, including (1) ≥17 IU/L reduction in alanine aminotransferase (ALT) in 53% of individuals in the exercise training group compared to 13% in the standard clinical care group (p < 0.001; mean reduction 24% vs. 10% respectively) and (2) improvement in CK18 (-61 vs. +71 ng/mL, p = 0.040). ALT improvement ≥17 IU/L was correlated with ≥30% relative reduction in magnetic resonance imaging-measured liver fat and PNPLA3 genotype. CONCLUSION Exercise training improves multiple serum biomarkers of liver fibroinflammation at clinically significant thresholds of response without body weight loss. This study provides further evidence that exercise training should be viewed as a weight-neutral intervention for which response to intervention can be readily monitored with widely available non-invasive biomarkers that can be applied at the population level.

Abstract
Metabolic-associated fatty liver disease (MAFLD) is the most prevalent chronic liver disease worldwide, affecting 25% of people globally and up to 80% of people with obesity. MAFLD is characterised by fat accumulation in the liver (hepatic steatosis) with varying degrees of inflammation and fibrosis. MAFLD is strongly linked with cardiometabolic disease and lifestyle-related cancers, in addition to heightened liver-related morbidity and mortality. This position statement examines evidence for exercise in the management of MAFLD and describes the role of the exercise professional in the context of the multi-disciplinary care team. The purpose of these guidelines is to equip the exercise professional with a broad understanding of the pathophysiological underpinnings of MAFLD, how it is diagnosed and managed in clinical practice, and to provide evidence- and consensus-based recommendations for exercise therapy in MAFLD management. The majority of research evidence indicates that 150-240 min per week of at least moderate-intensity aerobic exercise can reduce hepatic steatosis by ~ 2-4% (absolute reduction), but as little as 135 min/week has been shown to be effective. While emerging evidence shows that high-intensity interval training (HIIT) approaches may provide comparable benefit on hepatic steatosis, there does not appear to be an intensity-dependent benefit, as long as the recommended exercise volume is achieved. This dose of exercise is likely to also reduce central adiposity, increase cardiorespiratory fitness and improve cardiometabolic health, irrespective of weight loss. Resistance training should be considered in addition to, and not instead of, aerobic exercise targets. The information in this statement is relevant and appropriate for people living with the condition historically termed non-alcoholic fatty liver disease (NAFLD), regardless of terminology.

Abstract
INTRODUCTION Physical fitness assessed by the Liver Frailty Index (LFI) and 6-minute walk test (6MWT) informs the prognosis of liver transplant candidates, although there are limited data on its reversibility after prehabilitation. On a home-based exercise trial, we aimed to improve LFI and 6MWT and to investigate trial feasibility and intervention adherence. METHODS Liver transplant candidates with cirrhosis wore a personal activity tracker and used Exercise and Liver FITness app for 14 weeks, including a 2-week technology acclimation run-in. The 12-week intervention consisted of Exercise and Liver FITness app plus personal activity tracker and 15-/30-minute weekly calls with a physical activity coach aiming to complete ≥2 video-training sessions/week, or ≥500 step/d baseline increase for ≥8 weeks. We defined feasibility as ≥66% of subjects engaging in the intervention phase and adherence as ≥50% subjects meeting training end point. RESULTS Thirty-one patients (61 ± 7 years, 71% female, model for end-stage liver disease 17 ± 5, ∼33% frail) consented and 21 (68%) started the intervention. In the 15 subjects who completed the study, LFI improved from 3.84 ± 0.71 to 3.47 ± 0.90 ( P = 0.03) and 6MWT from 318 ± 73 to 358 ± 64 m ( P = 0.005). Attrition reasons included death (n = 4) and surgery (n = 2). There was 57% adherence, better for videos than for walking, although daily steps significantly increased (3,508 vs baseline: 1,260) during best performance week. One adverse event was attributed to the intervention. DISCUSSION Our clinical trial meaningfully improved LFI by 0.4 and 6MWT by 41 m and met feasibility/adherence goals. In-training daily step increase supported physical self-efficacy and intervention uptake, but maintenance remained a challenge despite counseling.

Abstract
BACKGROUND The prevalence of nonalcoholic fatty liver disease (NASH) and cryptogenic cirrhosis (CC) is constantly increasing in adolescents and young adults (AYAs). METHODS In a retrospective UNOS database evaluation, we analyzed postoperative outcomes of AYAs with nonalcoholic NASH/CC undergoing LT between January 1st, 2003 and March 5th, 2021. After exclusions, 85,970 LT recipients, 393 (47.1%) AYAs with NASH/CC and 441 (52.9%) AYAs with other metabolic conditions, were analyzed. RESULTS During the study period, the number of LTs performed for AYAs with NASH/CC increased from 4%-7% but decreased from 6.6%-5.3% compared to LTs performed for NASH/CC in all ages. In comparison to AYAs with other metabolic conditions, AYA LT recipients with NASH/CC had a higher prevalence of metabolic syndrome (MetS) components, including diabetes and increased body mass index (P < .0001 for both). Patient and graft survival in AYAs with NASH/CC were significantly lower in comparison to AYAs transplanted for other metabolic conditions (P < .0001) (Hazard Ratio = 1.93, P < .001). Patient survival in AYAs with NASH/CC was significantly better in comparison to older (40-65-year-old) patients with the same diagnosis (P = .01). CONCLUSIONS Our study found that the overall number of LTs in AYAs with NASH increased significantly, but to a lesser degree compared to the older population with the same diagnosis. Outcomes after LT in AYAs with NASH/CC were worse compared to LT for other metabolic conditions, but significantly better in comparison to older patients. The prevalence of LT for NASH/CC in AYAs is growing. MetS may contribute to worse outcomes in AYAs.

Abstract
BACKGROUND & AIMS Hospitalized patients with cirrhosis frequently undergo multiple procedures. The risk of procedural-related bleeding remains unclear, and management is not standardized. We conducted an international, prospective, multicenter study of hospitalized patients with cirrhosis undergoing nonsurgical procedures to establish the incidence of procedural-related bleeding and to identify bleeding risk factors. METHODS Hospitalized patients were prospectively enrolled and monitored until surgery, transplantation, death, or 28 days from admission. The study enrolled 1187 patients undergoing 3006 nonsurgical procedures from 20 centers. RESULTS A total of 93 procedural-related bleeding events were identified. Bleeding was reported in 6.9% of patient admissions and in 3.0% of the procedures. Major bleeding was reported in 2.3% of patient admissions and in 0.9% of the procedures. Patients with bleeding were more likely to have nonalcoholic steatohepatitis (43.9% vs 30%) and higher body mass index (BMI; 31.2 vs 29.5). Patients with bleeding had a higher Model for End-Stage Liver Disease score at admission (24.5 vs 18.5). A multivariable analysis controlling for center variation found that high-risk procedures (odds ratio [OR], 4.64; 95% confidence interval [CI], 2.44-8.84), Model for End-Stage Liver Disease score (OR, 2.37; 95% CI, 1.46-3.86), and higher BMI (OR, 1.40; 95% CI, 1.10-1.80) independently predicted bleeding. Preprocedure international normalized ratio, platelet level, and antithrombotic use were not predictive of bleeding. Bleeding prophylaxis was used more routinely in patients with bleeding (19.4% vs 7.4%). Patients with bleeding had a significantly higher 28-day risk of death (hazard ratio, 6.91; 95% CI, 4.22-11.31). CONCLUSIONS Procedural-related bleeding occurs rarely in hospitalized patients with cirrhosis. Patients with elevated BMI and decompensated liver disease who undergo high-risk procedures may be at risk to bleed. Bleeding is not associated with conventional hemostasis tests, preprocedure prophylaxis, or recent antithrombotic therapy.

Abstract
ABSTRACT Although physical activity (PA) is crucial in the prevention and clinical management of nonalcoholic fatty liver disease, most individuals with this chronic disease are inactive and do not achieve recommended amounts of PA. There is a robust and consistent body of evidence highlighting the benefit of participating in regular PA, including a reduction in liver fat and improvement in body composition, cardiorespiratory fitness, vascular biology, and health-related quality of life. Importantly, the benefits of regular PA can be seen without clinically significant weight loss. At least 150 min of moderate or 75 min of vigorous intensity PA are recommended weekly for all patients with nonalcoholic fatty liver disease, including those with compensated cirrhosis. If a formal exercise training program is prescribed, aerobic exercise with the addition of resistance training is preferred. In this roundtable document, the benefits of PA are discussed, along with recommendations for 1) PA assessment and screening; 2) how best to advise, counsel, and prescribe regular PA; and 3) when to refer to an exercise specialist.

Abstract
BACKGROUND & AIMS Cardiorespiratory fitness and liver fibrosis are independently associated with poor outcomes in patients with nonalcoholic steatohepatitis (NASH), however, conflicting reports exist about their relationship. We aimed to better characterize the relationship between cardiorespiratory fitness and liver histology in a cross-sectional study of patients with biopsy-proven NASH. METHODS Participants aged 18-75 years completed VO2peak fitness assessment using symptom-limited graded exercise testing. Participants were compared by liver fibrosis stage and NAFLD Activity Score (NAS). Multivariable models were constructed to assess factors related to relative VO2peak, including liver fibrosis and NAS. RESULTS Thirty-five participants with mean age 48 ± 12 years and body mass index 33.5 ± 7.6 kg/m2 were enrolled. Seventy-four percent of participants were female and 49% had diabetes. A dose-dependent relationship was found between relative VO2peak and liver fibrosis. Relative VO2peak was significantly lower in participants with advanced fibrosis (F3 disease- 15.7 ± 5.3 vs. ≤ F2 disease- 20.7 ± 5.9 mL/kg/min, p = 0.027). NAS > 5 was also associated with lower relative VO2peak (22.6 ± 5.7 vs. 16.5 ± 5.1 mL/kg/min, p = 0.012) compared to NAS ≤ 5. With multivariable modeling, advanced fibrosis remained independently predictive of relative VO2peak while NAS trended towards significance. DISCUSSION AND CONCLUSIONS Advanced liver fibrosis is independently associated with cardiorespiratory fitness in patients with NASH. This may explain the incremental increase in mortality as liver fibrosis stage increases. Further research is needed to determine if exercise training can improve cardiorespiratory fitness across multiple stages of liver fibrosis and directly reduce morbidity and mortality in patients with NASH.

Abstract
Exercise remains a key component of nonalcoholic fatty liver disease (NAFLD) treatment. The mechanisms that underpin improvements in NAFLD remain the focus of much exploration in our attempt to better understand how exercise benefits patients with NAFLD. In this review, we summarize the available scientific literature in terms of mechanistic studies which explore the role of exercise training in modulating fatty acid metabolism, reducing hepatic inflammation, and improving liver fibrosis. This review highlights that beyond simple energy expenditure, the activation of key receptors and pathways may influence the degree of NAFLD-related improvements with some pathways being sensitive to exercise type, intensity, and volume. Importantly, each therapeutic target of exercise training in this review is also the focus of previous or ongoing drug development studies in patients with nonalcoholic steatohepatitis (NASH), and even when a regulatory-agency-approved drug comes to market, exercise will likely remain an integral component in the clinical management of patients with NAFLD and NASH.

Abstract
BACKGROUND AIMS Lifestyle intervention remains the foundation of clinical care for patients with NASH; however, most patients are unsuccessful in enacting sustained behavioral change. There remains a clear unmet need to develop lifestyle intervention programs to support weight loss. Mobile health (mHealth) programs offer promise to address this need, yet their efficacy remains unexplored. APPROACH RESULTS We conducted a 16-week randomized controlled clinical trial involving adults with NASH. Patients were randomly assigned (1:1 ratio) to receive Noom Weight (NW), a mHealth lifestyle intervention program, or standard clinical care. The primary end point was a change in body weight. Secondary end points included feasibility (weekly app engagement), acceptability (>50% approached enrolled), and safety. Of 51 patients approached, 40 (78%) were randomly assigned (20 NW and 20 standard clinical care). NW significantly decreased body weight when compared to standard clinical care (-5.5 kg vs. -0.3 kg, p = 0.008; -5.4% vs. -0.4%, p = 0.004). More NW subjects achieved a clinically significant weight loss of ≥5% body weight (45% vs. 15%, p = 0.038). No adverse events occurred, and the majority (70%) of subjects in the NW arm met the feasibility criteria. CONCLUSIONS This clinical trial demonstrated that NW is not only feasible, acceptable, and safe but also highly efficacious because this mHealth lifestyle intervention program led to significantly greater body weight loss than standard clinical care. Future large-scale studies are required to validate these findings with more representative samples and to determine if mHealth lifestyle intervention programs can lead to sustained, long-term weight loss in patients with NASH.

Abstract
BACKGROUND AND AIMS We present findings from the inaugural American College of Sports Medicine (ACSM) International Multidisciplinary Roundtable, which was convened to evaluate the evidence for physical activity as a means of preventing or modifying the course of NAFLD. APPROACH AND RESULTS A scoping review was conducted to map the scientific literature and identify key concepts, research gaps, and evidence available to inform clinical practice, policymaking, and research. The scientific evidence demonstrated regular physical activity is associated with decreased risk of NAFLD development. Low physical activity is associated with a greater risk for disease progression and extrahepatic cancer. During routine health care visits, all patients with NAFLD should be screened for and counseled about physical activity benefits, including reduction in liver fat and improvement in body composition, fitness, and quality of life. While most physical activity benefits occur without clinically significant weight loss, evidence remains limited regarding the association between physical activity and liver fibrosis. At least 150 min/wk of moderate or 75 min/wk of vigorous-intensity physical activity are recommended for all patients with NAFLD. If a formal exercise training program is prescribed, aerobic exercise with the addition of resistance training is preferred. CONCLUSIONS The panel found consistent and compelling evidence that regular physical activity plays an important role in preventing NAFLD and improving intermediate clinical outcomes. Health care, fitness, and public health professionals are strongly encouraged to disseminate the information in this report. Future research should prioritize determining optimal strategies for promoting physical activity among individuals at risk and in those already diagnosed with NAFLD.

Abstract
Despite decades of bile acid research, diverse biological roles for bile acids have been discovered recently due to developments in understanding the human microbiota. As additional bacterial enzymes are characterized, and the tools used for identifying new bile acids become increasingly more sensitive, the repertoire of bile acids metabolized and/or synthesized by bacteria continues to grow. Additionally, bile acids impact microbiome community structure and function. In this Review, we highlight how the bile acid pool is manipulated by the gut microbiota, how it is dependent on the metabolic capacity of the bacterial community and how external factors, such as antibiotics and diet, shape bile acid composition. It is increasingly important to understand how bile acid signalling networks are affected in distinct organs where the bile acid composition differs, and how these networks impact infectious, metabolic and neoplastic diseases. These advances have enabled the development of therapeutics that target imbalances in microbiota-associated bile acid profiles.

Abstract
BACKGROUND AND AIMS Exercise remains a key component of nonalcoholic fatty liver disease (NAFLD) treatment. However, mechanisms underpinning the improvements in NAFLD seen with exercise are unclear. Exercise improved liver fat and serum biomarkers of liver fibrosis in the NASHFit trial. We investigated exercise's mechanism of benefit by conducting a post hoc analysis of these data to determine the relationship between serum fibroblast growth factor (FGF) 21, which is implicated in NAFLD development, and exercise. METHODS In the 20 wk NASHFit trial, patients with nonalcoholic steatohepatitis (NASH) were randomized to receive moderate-intensity aerobic exercise training or standard clinical care. Mediterranean-informed dietary counseling was provided to each group. Change in serum FGF21 was measured after an overnight fast. RESULTS There was a significant improvement in serum FGF21 with exercise training compared to standard clinical care (p = 0.037) with serum FGF21 reducing by 22% (-243.4 +/-349 ng/mL) with exercise vs. a 34% increase (+88.4 ng/mL +/-350.3 ng/mL) with standard clinical care. There was a large inverse association between change in serum FGF21 and change in cardiorespiratory fitness (VO2peak) (r = -0.62, 95% CI -0.88 to -0.05, p = 0.031), and on multivariable analysis, change in VO2peak remained independently associated with change in FGF21 (β = -44.5, 95% CI -83.8 to -5.11, p = 0.031). CONCLUSIONS Serum FGF21 is markedly decreased in response to aerobic exercise training, offering a novel mechanism to explain the observed reduction in liver fat and improvement in serum biomarkers of liver fibrosis in patients with NASH who do exercise.

Abstract
BACKGROUND & AIMS Physical activity offers promise to protect against multiple non-hepatic primary cancers. We performed a systematic review to quantify the association between physical activity and hepatocellular carcinoma (HCC) risk. METHODS We searched the Cochrane Library, Embase, Medline and trial registries through December 2020 for studies that measured physical activity levels in adults at risk for HCC. The primary outcome was HCC. Subgroup analysis was performed limiting to vigorous physical activity. Proportions and random-effects odds ratios (OR) with corresponding 95% confidence intervals (CI) were calculated. RESULTS Seven studies met inclusion criteria, comprising 777,662 subjects (median age 55 years; 55% female). Greater amounts of physical activity were associated with less HCC (OR 0.65, 95% CI 0.45-0.95, p = 0.03) compared to lower amounts. Vigorous physical activity was associated with even less HCC (OR 0.62, 95% CI 0.49-0.79, p < 0.01). CONCLUSIONS This meta-analysis demonstrates that greater amounts of physical activity are associated with lower odds of HCC. These results support the use of regular physical activity as an effective way to prevent HCC and provide helpful data to support a for future exercise-based interventional study to better define the optimal exercise prescription for patients at risk for primary liver cancer.

Abstract
OBJECTIVES Chronic liver disease is often associated with testosterone deficiency. However, testosterone replacement does not improve hepatic function or survival with diseased liver. So far, to our knowledge, testosterone replacement therapy after successful livertransplantforfunctional sarcopenia has not been studied. We had 3 goals: (1) define postoperative functional sarcopenia afterlivertransplant with serum testosterone level; (2) examine the role of short-term testosterone replacement therapy with active in-bed exercise of upper and lower extremity joints; and (3) correlate functional sarcopenia with skeletal muscle index and skeletal muscle density in relation to ascites, pleural effusion subtracted body mass index. MATERIALS AND METHODS We evaluated 16 liver transplant recipients who had been receiving posttransplanttestosterone replacementtherapy with functional sarcopenia. Preoperative and postoperative demographics and laboratory and radiological data were retrieved; body mass index, skeletal muscle index, and skeletal muscle density were calculated. For this retrospective study, institutional review board approval was obtained before the electronic database was reviewed and analyzed. RESULTS Mean testosterone level was 28.3 ng/dL (<5% of expected). Twelve patients received 1 dose, and the remaining 4 patients received >1 dose oftestosterone cypionate, 200 mg. Mean hospital stay was 26 days. Seven patients were discharged home, with the remaining patients to a rehabilitation facility or nursing home. One patient died from a cardiac event, and another patient died from recurrent metastatic malignancy. The 1-year and 5-year actuarial patient and graft survival rates were 93.8% and 87.5%, respectively. Overall, 5 patients were sarcopenic by skeletal muscle index, and 6 patients had poor muscle quality by skeletal muscle density. CONCLUSIONS Testosterone deficiency after liver transplant exists with functional sarcopenia. Two- thirds of such recipients have low skeletal muscle index and/or have low skeletal muscle density. Short- term testosterone replacement therapy with in-bed active exercise provides 5-year patient and graft survival of 87.5%.

Abstract
BACKGROUND AND AIMS NASH is a common disease associated with increased rates of thromboembolism (TE). Although exercise training can lessen thrombotic risk in patients with vascular disease, whether similar findings are observed in patients with NASH is open for study. APPROACH AND RESULTS We conducted a 20-week randomized controlled clinical trial involving patients with biopsy-confirmed NASH. Patients were randomly assigned (2:1 ratio) to receive either an exercise training program or standard clinical care. The primary endpoint was change in plasminogen activator inhibitor 1 (PAI-1) level, an established thrombotic biomarker. Twenty-eight patients were randomly assigned (18 exercise training and 10 standard clinical care). PAI-1 level was significantly decreased by exercise training when compared to standard clinical care (-40 ± 100 vs. +70 ± 63 ng/ml; p = 0.02). Exercise training decreased MRI proton density fat fraction (MRI-PDFF; -4.7 ± 5.6 vs. 1.2 ± 2.8% absolute liver fat; p = 0.01); 40% of exercise subjects had a ≥30% relative reduction in MRI-PDFF (histological response threshold) compared to 13% for standard of care (p < 0.01). Exercise training improved fitness (VO2 peak, +3.0 ± 5.6 vs. -1.8 ± 5.1 ml/kg/min; p = 0.05) in comparison to standard clinical care. CONCLUSIONS This clinical trial showed that, independent of weight loss or dietary change, exercise training resulted in a significantly greater decrease in thrombotic risk than standard clinical care in patients with NASH, in parallel with MRI-PDFF reduction and improvement in fitness. Future studies are required to determine whether exercise training can directly impact patient outcomes and lower rates of TE.

Abstract
BACKGROUND Functional status (FS) is dynamic and changes over time. We examined how changes in FS while awaiting liver transplantation influence post-transplant outcomes. METHODS Data on adult liver transplants performed in the United States during the MELD era were obtained through September 2020. Patient and graft survival were compared between groups with no change or improved FS, and those with worsening FS. RESULTS Of the 90,210 transplant recipients included in the analysis, 39,193 (43%) had worsening FS, which was associated with longer waiting-list time (187 vs. 329 days, p < 0.001) and worse patient survival after liver transplant (1858 vs. 1727 days, p < 0.001). A consistent and dose-dependent relationship was observed for each 10-point decrease in Karnofsky Performance Score and post-transplant survival. Multivariable regression analysis confirmed that a decline in FS was associated with worse patient survival (HR 1.15, p < 0.001). Similar findings were observed for graft survival. CONCLUSION A decline in FS on the waiting-list is associated with significantly greater post-liver transplant mortality in recipients. These results should be taken into consideration when allocating organs and determining transplant candidacy. Strategies to optimize FS prior to transplantation should be prioritized as even subtle decreases in FS are associated with inferior post-transplantation outcomes.

Abstract
AIM Colorectal cancer (CRC) is the third most deadly and fourth most common cancer worldwide. Early detection, resection, and appropriate surveillance of precursor polyps result in better outcomes. Colonoscopy is a safe, accurate, and effective tool for surveillance and follow-up of premalignant polyps. Recommended surveillance intervals are based on polyp, procedural, and patient-related factors. The United States Multi-Society Task Force (MSTF) on CRC publishes guidelines with periodic updates on surveillance. We sought to evaluate adherence to post-polypectomy surveillance guidelines by academic gastroenterologists at a high-volume center. METHODS One-year retrospective study evaluating compliance with post-polypectomy recommendations after average risk adult screening colonoscopies. Data was collected on number and size of polyps, quality of bowel prep, initial follow-up recommendations, polyp pathology, and follow-up recommendations. Correlation with the 2012 MSTF guidelines was also evaluated. Endoscopist experience was categorized as greater or less than 10 years of practice experience. Binomial regression was used to model the association between the providers' years of experience (<10 vs. >10) and the likelihood of agreement between initial assessment and post-pathology assessment. RESULTS There was a greater than 85% adherence to post-polypectomy surveillance guidelines, independent of endoscopist experience. CONCLUSION There is a high level of adherence to post-polypectomy guidelines by practicing academic gastroenterologists independent of post-fellowship clinical experience.

Abstract
BACKGROUND & AIMS Antiepileptic drugs (AEDs) are a common cause of drug-induced liver injury (DILI). Over the last few decades, several newer AEDs were approved for marketing in the United States, and they are increasingly prescribed for indications other than seizures. Contemporaneous data related to trends and characteristics of AED-related liver injury are sparse. METHODS We report the trends, characteristics, and outcomes of patients with AED-related DILI enrolled into the DILIN Prospective Study between 2004 and 2020. RESULTS Among 1,711 participants with definite, highly likely, or probable DILI, 66 (3.9%) had AED-related DILI (lamotrigine [n = 18], phenytoin [n = 16], carbamazepine [n = 11], valproate [n = 10], gabapentin [n = 4], and others [n = 7]). The frequency of AED-related liver injury significantly decreased during the study period (from 8.5% of cases during 2004-2007 to 2.6% during 2015-2020, p = 0.01). AEDs other than phenytoin were commonly prescribed for non-seizure indications. Compared to non-AEDs, patients with AED-related liver injury were younger (mean age 38.5 vs. 50.1 years-old, p <0.001) and more likely African American (27% vs. 12%, p = 0.008). DRESS was common with liver injury caused by lamotrigine, phenytoin, and carbamazepine, but not valproate or gabapentin. Liver injury severity was moderate to severe in the majority: 5 died, and 3 underwent orthotopic liver transplantation (OLT). No patient with lamotrigine-related DILI, including 13 with hepatocellular jaundice, died or needed OLT, while 3 out of 16 patients (19%) with phenytoin-related DILI either died or required OLT. CONCLUSION The frequency of AED-related liver injury significantly decreased over the last 2 decades in our experience. AED-related liver injury has several distinctive features, including a preponderance in African American patients and those with immunoallergic skin reactions, with outcomes depending on the type of AED involved. LAY SUMMARY Medications used to treat epilepsy may sometimes cause severe liver injury. However, several new medications have been approved over the last 2 decades and they may not be as toxic to the liver as older antiepileptic medications (AEDs). This study shows that overall liver injury due to AEDs is decreasing, likely due to decreasing use of older AEDs. Liver injury due to AEDs appears to be more common in African Americans and is commonly associated with allergic skin reactions.

Abstract
BACKGROUND & AIMS Magnetic resonance imaging proton density fat fraction (MRI-PDFF) offers promise as a non-invasive biomarker of treatment response in early-phase nonalcoholic steatohepatitis (NASH) trials. We performed a systematic review to quantify the association between a ≥ 30% reduction in MRI-PDFF and histologic response in NASH. METHODS We searched the Cochrane Library, Embase, Medline and trial registries through May 2020 for early-phase clinical trials that incorporated MRI-PDFF and examined histologic response following intervention in adults with NASH. Subjects were classified as MRI-PDFF responders (relative decline in liver fat ≥30%) or non-responders (relative decline in liver fat <30%). MRI-PDFF responders versus non-responders were compared. Primary outcome was histologic response defined as a 2-point improvement in NAFLD Activity Score with at least 1-point improvement in lobular inflammation or ballooning. Secondary outcome was NASH resolution. Proportions and random effects odds ratios (OR) with corresponding 95% confidence intervals (CI) were calculated. RESULTS Seven studies met inclusion criteria, comprising 346 subjects (median age 51 years; 59% female; 46% with diabetes). MRI-PDFF responders were significantly more likely to have a histologic response (51% vs 14%, P < .001; OR 6.98, 95% CI 2.38-20.43, P < .001) and NASH resolution (41% vs 7%, P < .001; OR 5.45, 95% CI 1.53-19.46, P = .009) compared to non-responders. CONCLUSIONS This meta-analysis demonstrates that a ≥30% relative decline in MRI-PDFF is associated with higher odds of histologic response and NASH resolution. These results support the use of MRI-PDFF in non-invasive monitoring of treatment response in early-phase NASH clinical trials and provide helpful data for sample-size estimation for histology-based assessment.

Abstract
BACKGROUND Lifestyle changes, including physical activity, are the cornerstones of the treatment of nonalcoholic fatty liver disease (NAFLD). For unclear reasons, most NAFLD patients do not achieve the recommended amount of weekly activity. AIMS Our aim was to measure perceived barriers to physical activity and enablers to exercise intervention. METHODS Consecutive subjects aged 18-70 with NAFLD were prospectively enrolled. An exercise motivation questionnaire was administered to assess current behaviors and perceived barriers. RESULTS Eighty-seven subjects (60% female) were enrolled with mean age 52 years and mean body mass index (BMI) 34.5 kg/m2. Metabolic comorbidities were common: 49% had hyperlipidemia, 42% hypertension, and 40% diabetes. The majority (75%) did not achieve ≥ 150 min/week of physical activity. Ninety-one percent agreed that activity was important in improving NAFLD; 88% desired to be more active. Lack of exercise resources and education from treating provider (47%), physical discomfort during exercise (44%), and time constraints (32%) were the most common barriers. Rates of fitness tracker (34%), gym (33%), exercise program (33%), and personal trainer (17%) use were low. CONCLUSIONS While nearly all subjects with NAFLD identify physical activity to be important and desire to be more active, only a few meet activity recommendations. This discordance is due to a perceived lack of resources and education, physical discomfort, and time constraints. Better understanding of these barriers and behaviors are important to improve morbidity and mortality in NAFLD. Future behavioral research removing the identified barriers is of great importance to global public health and should be prioritized.

Abstract
Background Most patients with nonalcoholic fatty liver disease (NAFLD) are physically inactive despite the well-known benefits of physical activity. Telehealth offers promise as a novel way to deliver an exercise training program and increase physical activity. However, the feasibility, safety, and efficacy of telehealth-based exercise programs is unknown in patients with NAFLD. Objective The aim of this study was to determine the feasibility of a directly supervised exercise training program delivered exclusively with telehealth to patients with nonalcoholic steatohepatitis (NASH), the progressive form of NAFLD. Methods In response to COVID-19 research restrictions, we adapted an existing clinical trial and delivered 20 weeks of moderate-intensity aerobic training 5 days a week under real-time direct supervision using an audio–visual telehealth platform. Aerobic training was completed by walking outdoors or using a home treadmill. Fitness activity trackers with heart rate monitors ensured exercise was completed at the prescribed intensity with real-time feedback from an exercise physiologist. Results Three female patients with biopsy-proven NASH were enrolled with a mean age of 52 (SD 14) years. The mean body mass index was 31.9 (SD 5.1) kg/m2. All patients had metabolic syndrome. All patients completed over 80% of exercise sessions (mean 84% [SD 3%]) and no adverse events occurred. Body weight (mean –5.1% [SD 3.7%]), body fat (mean –4.4% [SD 2.3%]), and waist circumference (mean –1.3 in. [SD 1.6 in.]) all improved with exercise. The mean relative reduction in magnetic resonance imaging-proton density fat fraction (MRI-PDFF) was 35.1% (SD 8.8%). Mean reductions in hemoglobin A1c and Homeostatic Model Assessment for Insulin Resistance were also observed (–0.5% [SD 0.2%] and –4.0 [SD 1.2], respectively). The mean peak oxygen consumption (VO2peak) improved by 9.9 (SD 6.6) mL/kg/min. Conclusions This proof-of-concept study found that supervised exercise training delivered via telehealth is feasible and safe in patients with NASH. Telehealth-based exercise training also appears to be highly efficacious in patients with NASH, but this will need to be confirmed by future large-scale trials.

Abstract
Non-alcoholic fatty liver disease (NAFLD) currently affects more than 25% of the world population and is rising. NAFLD can progress to non-alcoholic steatohepatitis that is associated with hepatic inflammation and fibrosis and can result in cirrhosis with subsequent liver failure. Non-alcoholic steatohepatitis (NASH) has now emerged as one of the leading etiologies for a liver transplant among adults in the United States. Given the rising incidence of liver transplants in patients with NASH-related cirrhosis, it is essential for anesthesiologists to be familiar with this condition as well as with NASH-related comorbidities and perioperative complications. Not only is NASH linked to metabolic syndrome, but it also is independently associated with cardiovascular disease, renal and thyroid dysfunction, obstructive sleep apnea (OSA), and a hypercoagulable state. The association with these conditions can affect the perioperative outcome of these patients, particularly because of increased mortality from major adverse cardiovascular events and sepsis. In order to decrease the perioperative morbidity and mortality of patients with NASH undergoing a liver transplant, a multidisciplinary approach to their perioperative management is essential, along with careful preoperative evaluation and aggressive intraoperative and postoperative monitoring. The focus of this review article is to provide a comprehensive overview of challenges associated with liver transplants in patients with NASH and to provide suggestions for appropriate patient selection and perioperative management.

Abstract
INTRODUCTION Inflammatory bowel disease (IBD) patients are at greater risk of developing colorectal cancer (CRC). Detection of precursor dysplasia is important for cancer prevention. Recent guidelines recommend dye chromoendoscopy (DCE) as the preferred method for dysplasia detection. Universal adoption of DCE is time-consuming and may limit endoscopy access. The benefit of universal application of the guidelines is unclear. We compared high-definition white-light colonoscopy (HD-WLC) with DCE for dysplasia detection in IBD patients. METHODS We conducted a retrospective case-control study of adult IBD patients undergoing dysplasia surveillance between September 1, 2015, and February 1, 2020. DCE cases were matched to HD-WLC in a 1:1 ratio for gender, IBD diagnosis, and age. DCE patients were considered high risk for colorectal cancer by the referring provider. RESULTS A total of 187 subjects were enrolled. Majority were males, were Caucasian, and had longstanding IBD (primarily ulcerative colitis). Baseline characteristics were similar between the two groups, except for history of surgery, duration of IBD, and history of dysplasia. There was no significant difference in dysplasia detection between DCE and HD-WLC (10.2% vs 6.7%, p = 0.39). More polyps were detected in the DCE arm compared with the HD-WLC group (1.35 vs 0.80, p = 0.018), but adenoma detection rate was not statistically different between the two groups (10.2% vs 9.0%, p = 0.31). Mean withdrawal time was longer in the DCE group (24.6 min vs 15.4, p < 0.001). CONCLUSIONS There were no differences in dysplasia detection using DCE compared with HD-WLC, although withdrawal times were longer with DCE.

Abstract
Nonalcoholic fatty liver disease is the leading cause of liver disease worldwide. It has expansive extrahepatic morbidity and mortality including increased rates of both cardiovascular disease and venous thromboembolism. Derangements in primary, secondary and tertiary hemostasis are found in nonalcoholic fatty liver disease independent of those ascribed to end-stage liver disease. The abnormalities across all stages of hemostasis explain the increased rates of clinically relevant thrombotic events, including pulmonary embolism, deep vein thrombosis and portal vein thrombosis, which on an epidemiologic basis appears to be independent of obesity and other traditional venous thromboembolic risk factors. However, given the complex interaction between obesity, body composition and nonalcoholic fatty liver disease and the potential for exercise to benefit all three, more research is needed to further define the role of each in contributing to the prohemostatic state of nonalcoholic fatty liver disease in order to improve patient oriented outcomes.

Abstract
INTRODUCTION Nonalcoholic fatty liver disease (NAFLD) is the leading cause of liver disease worldwide. Nonalcoholic steatohepatitis (NASH), is a more severe type of NAFLD. Exercise improves NASH, by reversing steatosis, and may arrest fibrosis. However, the mechanisms underlying these interactions are unknown. AMP-activated protein kinase (AMPK) is a fuel-sensing enzyme that is activated by energy stress. Mammalian target of rapamycin in complex 1 (mTORC1) is a nutrient sensor that regulates protein synthesis. In NASH, AMPK activity is low and mTORC1 is high. In healthy persons, exercise activates AMPK and suppresses mTORC1. We examined the effects of exercise on hepatic ribosomal protein S6 phosphorylation, a downstream target of AMPK and mTORC1 in patients with NASH. METHODS Three subjects with biopsy-proven NASH underwent a structured, 20-week aerobic exercise intervention, five-days a week for 30-min at a moderate intensity (40-55% of VO2max). Immunofluorescence staining for rpS6 phosphorylation in hepatic tissue was quantified by ImageJ software. RESULTS Following 20-weeks of aerobic exercise, rpS6 levels were significantly attenuated (3.9 ± 1.9 pre-exercise vs. 1.4 +/0.4 post-exercise, p = 0.04). CONCLUSIONS These findings suggest exercise modulates the AMPK/mTORC1 pathway in patients with NASH and may guide the design of future studies into the mechanism of how exercise improves NASH and possibly reverses fibrosis.

Abstract
Purpose of review Nonalcoholic fatty liver disease (NAFLD) is a leading cause of global liver disease. Because current pharmacologic treatments are ineffective, lifestyle change centered on exercise remains the most effective NAFLD treatment. The aim of this systematic review is to summarize and evaluate the current evidence supporting the use of exercise training as a medical treatment for adult patients with NAFLD. Recent findings At least 150 minutes each week of moderate intensity exercise of any type can improve NAFLD, both with and without modest weight loss. Exercise training reduces hepatic steatosis and liver inflammation, favorably changes body composition, improves vascular endothelial function, increases cardiorespiratory fitness and can lead to histologic response. To date, exercise-based NAFLD trials are limited by small sample size and significant heterogeneity. Summary While several key questions remain unanswered, exercise training will always be an important part of the medical management of patients with NAFLD.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease worldwide affecting upwards of one third the global population. For reasons not fully understood, individuals with NAFLD and its more severe variant, nonalcoholic steatohepatitis (NASH), are at increased risk for venous thromboembolism which significantly increases morbidity and mortality. Lifestyle changes centering around exercise training are the mainstay of treatment for NAFLD/NASH. While exercise training can lessen venous thromboembolic risk in healthy persons and those with cardiovascular disease, whether or not this benefit is seen in patients with NAFLD/NASH remains unknown. In order to better understand how exercise training impacts thrombosis risk in NAFLD, we present the design of a thirty-two week randomized controlled clinical trial of 42 sedentary subjects age 18-69 with biopsy proven NASH. The main aim is to determine the impact of an aerobic exercise training program on the abnormal hemostatic system unique to NAFLD/NASH. The main outcome is change in plasminogen activator inhibitor one level, an established marker for venous thromboembolism. Secondary outcomes include body composition, cardiorespiratory fitness, control of comorbid metabolic conditions (e.g., obesity, hypertension, hyperlipidemia, diabetes), dietary composition, health related quality of life, liver enzymes and histology, NAFLD/NASH disease activity (e.g., biomarkers, clinical decision aids), microbiome, other markers of hemostasis, and PNPLA3 gene expression. The study represents the first clinical trial of an exercise training program to reduce elevated clotting risk in subjects with NAFLD/NASH.

Abstract
INTRODUCTION AND AIM Hemostatic disorders in chronic liver disease and cirrhosis show continued expansion of research efforts. However, clinical decision making is often practiced on an individual patient level as consensus guidelines are lacking. We aimed to better assess individual day-to-day clinical practice through gauging clinicians' responses to common clinical scenarios. MATERIALS AND METHODS A series of ten clinical scenarios (seven procedural coagulation and three thrombosis management) were posed to conference attendees utilizing real-time polling software (Poll Everywhere). Responses were binomial and were submitted as "Agree" or "Disagree." Results were displayed real time following a standardized response period and an open-forum discussion ensued between conference faculty and attendees following response submission. RESULTS Twenty conference attendees participated in the clinical scenario plenary session. In general, agreement rates were high. All but one of the ten clinical scenarios had ≥ 70% agreement. Agreement was based both on procedural risk, with greatest agreement seen for low-risk procedures (80-93%), and on peri-procedural coagulation parameters of platelet count and fibrinogen level where > 50,000μ/L and 120 mg/dL were the most agreed upon thresholds, respectively. 75-95% agreement was reached when surveying the need for anticoagulation for mesenteric vein thrombosis in liver transplant candidates; slightly less (71%) agreement was found when deciding to proceed with anticoagulation in non-liver transplant candidates with mesenteric vein thrombosis. CONCLUSIONS While large-scale, methodologically rigorous randomized controlled trials are lacking to guide clinical decision making in patients with coagulation disorders and chronic liver disease, consensus expert opinion regarding mitigating peri-procedural bleeding risk and treatment of thrombosis appears consistent and strong.

Abstract
Chronic hepatitis C virus (HCV) is a risk factor for type 2 diabetes. In the era of interferon-based HCV therapy, type 2 diabetes was associated with decreased likelihood of sustained virologic response (SVR). Preliminary studies suggest that type 2 diabetes may not reduce the efficacy of regimens involving direct-acting antiviral (DAA) medications. We aimed to determine whether preexisting type 2 diabetes is associated with a reduced rate of SVR achieved 12 weeks after treatment of HCV with DAA-based regimens.

Abstract
INTRODUCTION AND OBJECTIVES Liver transplantation candidates are among the most comorbid patients awaiting lifesaving intervention. Health related quality of life (HRQOL) measured by instruments that incorporate dynamic computerized adaptive testing, could improve their assessment. We aimed to determine the feasibility of administration of the Patient-Reported Outcomes Measurement Information System (PROMIS-CAT) in liver transplant candidates. MATERIALS AND METHODS Liver transplantation candidates were prospectively enrolled following a review of their available medical history. Subjects were given a tablet computer (iPad) to access the pre-loaded PROMIS CAT. RESULTS 109 candidates with mean age 55.6±8.6 years were enrolled in this pilot study. Mean MELD-Na score was 16.3±6.3; 92.6% had decompensated liver disease. Leading etiologies of cirrhosis included hepatitis C (34.8%), nonalcoholic steatohepatitis (25.7%) and alcohol (21.1%). Subjects with MELD-Na score>20 had the most significant impairment in HRQOL (anxiety/fear+5.9±2.7, p=0.0289, depression+5.1±2.5, p=0.0428, fatigue+4.3±2.6, p=0.0973) and physical impairment (-7.8±2.5, p=0.0022). Stage of cirrhosis and decompensated liver disease were predictive of impaired HRQOL but Child-Pugh Turcotte score was not. Hepatic encephalopathy was the strongest independent predictor of impaired HRQOL, with significant impairment across all domains of health. CONCLUSIONS Liver transplant candidates have significantly impaired HRQOL across multiple domains of health as measured by PROMIS-CAT. HRQOL impairment parallels disease severity. Future study is needed to determine how best HRQOL could be systematically included in liver transplantation listing policy, especially in those candidates with hepatic encephalopathy.

Abstract
Portal vein thrombosis (PVT) is associated with inferior pretransplantation and posttransplantation outcomes. We aimed to create a predictive model to risk stratify transplant candidates for PVT. Data on adult transplants in the United States during the Model for End-Stage Liver Disease (MELD) era through September 2016 were reviewed. We constructed and validated a scoring system composed of routine, readily available clinical information to predict the development of incident PVT at 12 months from transplantation listing. A total of 66,568 liver transplant candidates were dichotomized into 2 groups to construct (n = 34,751) and validate (n = 31,817) a scoring system. In general, the derivation and validation cohorts were clinically similar. Although nonalcoholic steatohepatitis was a significant predictor of incident PVT (hazard ratio, 1.29; 95% confidence interval, 1.08-1.54; P < 0.001), age, MELD score, and moderate-to-severe ascites were also associated with increased risk. African American race was associated with decreased risk. A scoring system (PVT risk index [RI]) of these 5 variables had an area under the curve of 0.71 and 0.70 in both derivation and validation cohorts, respectively. By applying the low cutoff score of 2.6, incident PVT could be accurately excluded (negative predictive value 94%). Using the high cutoff score of 4.6 (positive predictive value 85%), PVT could be diagnosed with high accuracy. The PVT-RI predicts which candidates awaiting lifesaving liver transplantation will and will not develop future PVT. Although this scoring system will require prospective validation, it provides a powerful new tool for the clinician when risk stratifying cirrhosis patients prior to liver transplantation for future PVT development.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is common in cirrhosis. PVT is associated with high morbidity and mortality. Individual reports suggest that PVT occurs more frequently in patients with cirrhosis and inherited thrombophilia. The relationship between cirrhosis, PVT development, and inherited thrombophilia was explored in this study. The aim of the study was to determine whether cirrhotic patients with nontumoral PVT have an increased rate of inherited thrombophilia. METHODS Studies were identified by searching electronic databases up to October 2017 with English language and human subject restrictions. Two independent reviewers screened citations and extracted data. Magnitude of effect was calculated to obtain aggregate estimates of effect size and 95% confidence intervals (CIs). Between-study variability and heterogeneity were assessed. RESULTS Of 2893 citations identified, 9 studies composed of 1929 subjects with cirrhosis were included. The overall prevalence of PVT was 6.5% (n = 125). Both prothrombin G20210A mutation (odds ratio [OR], 2.43; 95% CI, 1.07-5.53; P = 0.03) and factor V Leiden (FVL) (OR, 1.98; 95% CI, 1.06-3.68; P = 0.03) were significantly associated with PVT risk. Methyltetrahydrofolate reductase C677T mutation was not associated with increased PVT risk. No heterogeneity or publication bias was observed. One important study with opposite findings could not be included due to lack of primary data. CONCLUSIONS FVL and PTG20210A mutation were associated with increased PVT risk in patients with cirrhosis. This finding reframes the role of inherited thrombophilia in PVT development in patients with cirrhosis. Future prospective studies investigating screening for inherited thrombophilia in all cirrhosis patients with PVT seem warranted.

Abstract
BACKGROUND This retrospective UNOS database evaluation analyzes the prevalence of preoperative portal vein thromboses (PVT), and postoperative thromboses leading to graft failure in pediatric patients undergoing liver transplantation (LT). METHODS The evaluation was performed in three age groups: I (0-5), II (6-11), III (12-18) years old. Factors predictive of pre- and postoperative thromboses were analyzed. RESULTS Between 2000 and 2015, 8982 pediatric LT were performed in the US. Of those, 390 patients had preoperative PVT (4.3%), and 396 (4.4%) had postoperative thromboses. The prevalence of both types of thromboses was less in Group III than in the other two groups (3.20% vs 4.65%, p = 0.007 and 1.73% vs. 5.13%, p < 0.001, respectively). The prevalence of postoperative thromboses was significantly higher in Group I than in the other two groups (5.49% vs. 2.51%, p < 0.001). Preoperative PVT was independently associated with postoperative thromboses (OR = 1.7, p = 0.02). Children less than 5 years of age were more likely to develop postoperative thromboses leading to graft failure (OR = 2.9, p < 0.001). CONCLUSION Younger children undergoing LT are prone to pre-and postoperative thrombotic complications. Preoperative PVT at the time of transplantation was independently associated with postoperative thromboses. Perioperative antithrombotic therapy should be considered in pediatric patients undergoing LT.

Abstract
Non-tumoral portal vein thrombosis (PVT) remains a highly relevant topic in the field of hepatology and liver transplantation with much surrounding controversy. Although multiple studies have shown that PVT is associated with adverse outcomes with increased morbidity and mortality rates, others have not reported the same clinical impact of PVT, arguing rather that incident PVT reflects worsening portal hypertension and the natural history of the disease. Despite this uncertainly, PVT is a dilemma facing the clinician on a daily basis often requiring a multidisciplinary team-based approach between hepatologists, transplant surgeons, interventional radiologists and hematologists. In this review, the authors provide a summary of the evidence supporting best clinical practices in the management of non-tumoral PVT in patients with cirrhosis.
