Incidence of liver cancer in young adults according to the Global Burden of Disease database 2019.

BACKGROUND AND AIMS: The worldwide burden of cancer is increasing in younger populations. However, the epidemiology of primary liver cancer remains understudied in young adults compared to other cancer forms. APPROACH AND RESULTS: This study analyzed data from the Global Burden of Disease study between 2010 and 2019 to assess the age-standardized incidence, mortality, and disability-adjusted life years associated with primary liver cancer in the young (15-49 y), stratified by region, nation, sociodemographic index, and sex. The study found a global estimate of 78,299 primary liver cancer cases, 60,602 deaths, and 2.90 million disability-adjusted life years in the young population. The Western Pacific region exhibited the highest burden in 2019, showing the most significant increase compared to other regions between 2010 and 2019. More than half of the countries worldwide have undergone an increase in primary liver cancer incidence rates in young adults. Around 12.51% of deaths due to primary liver cancer occur in young individuals. Throughout the study period, there was a significant decline in primary liver cancer mortality due to most etiologies, except for metabolic dysfunction-associated steatotic liver disease-attributable primary liver cancer (annual percentage change + 0.87%, 95% CI: 0.70%-1.05%) and alcohol-attributable primary liver cancer (annual percentage change + 0.21%, 95% CI: 0.01%-0.42%). The limitations of the Global Burden of Disease database include reliance on the quality of primary data and possible underestimation of alcohol consumption. CONCLUSIONS: Over the past decade, there has been a marked increase in the burden of primary liver cancer, especially that originating from steatotic liver disease. This trend calls for the development of urgent and comprehensive strategies to mitigate this rising burden globally.

The Global Burden of Alcohol-associated Cirrhosis and Cancer in Young and Middle-aged Adults.

Alcohol is a substance that impacts premature mortality and morbidity.1 The liver is invariably subjected to the impact of alcohol, which can result in cirrhosis and cancer. Alcohol also has detrimental effects that extend beyond the liver. While traditionally associated with advanced age, emerging data reported a rising burden of cancers and alcohol-associated liver disease in the young.1-3 Thus, the primary objective was to evaluate the trend of alcohol-associated cirrhosis and cancer in young and middle-aged adults (aged 15-49) utilizing the Global Burden of Disease Study (GBD) 2019.4 We chose the age group less than 50 years old based on the definition of early-onset cancer and the inherent selection of the age group in the GBD database.4-6 The detailed methods are provided in the Supplementary Appendix. Briefly, data were sourced from population-based cancer registries, vital registration systems, or verbal autopsy studies. Verbal autopsy is a well-established approach for monitoring health, providing valuable information on mortality patterns and the reasons behind deaths in areas lacking robust medical death certification processes. The researchers employed the Cause of Death Ensemble model to estimate the burden linked to cancer and cirrhosis associated with alcohol use.

PNPLA3 Genotype and Diabetes Identify Patients With Nonalcoholic Fatty Liver Disease at High Risk of Incident Cirrhosis.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) can progress to cirrhosis and hepatic decompensation, but whether genetic variants influence the rate of progression to cirrhosis or are useful in risk stratification among patients with NAFLD is uncertain. METHODS: We included participants from 2 independent cohorts, they Michigan Genomics Initiative (MGI) and UK Biobank (UKBB), who had NAFLD defined by elevated alanine aminotransferase (ALT) levels in the absence of alternative chronic liver disease. The primary predictors were genetic variants and metabolic comorbidities associated with cirrhosis. We conducted time-to-event analyses using Fine-Gray competing risk models. RESULTS: We included 7893 and 46,880 participants from MGI and UKBB, respectively. In univariable analysis, PNPLA3-rs738409-GG genotype, diabetes, obesity, and ALT of ≥2× upper limit of normal were associated with higher incidence rate of cirrhosis in both MGI and UKBB. PNPLA3-rs738409-GG had additive effects with clinical risk factors including diabetes, obesity, and ALT elevations. Among patients with indeterminate fibrosis-4 (FIB4) scores (1.3-2.67), those with diabetes and PNPLA3-rs738409-GG genotype had an incidence rate of cirrhosis comparable to that of patients with high-risk FIB4 scores (>2.67) and 2.9-4.8 times that of patients with diabetes but CC/CG genotypes. In contrast, FIB4 <1.3 was associated with an incidence rate of cirrhosis significantly lower than that of FIB4 of >2.67, even in the presence of clinical risk factors and high-risk PNPLA3 genotype. CONCLUSIONS: PNPLA3-rs738409 genotype and diabetes identified patients with NAFLD currently considered indeterminate risk (FIB4 1.3-2.67) who had a similar risk of cirrhosis as those considered high-risk (FIB4 >2.67). PNPLA3 genotyping may improve prognostication and allow for prioritization of intensive intervention.

Global prevalence, clinical characteristics, surveillance, treatment allocation, and outcomes of alcohol-associated hepatocellular carcinoma.

BACKGROUND AND AIMS: Although the burden of alcohol-associated hepatocellular carcinoma (HCC) is increasing with rising alcohol consumption, clinical presentation and outcomes of alcohol-associated HCC have not been systematically assessed. We aimed to determine the prevalence, clinical characteristics, surveillance rates, treatment allocation, and outcomes of alcohol-associated HCC. METHODS: Medline and Embase were searched from inception to January 2023. Proportional data were analyzed using a generalized linear mixed model. The odds ratio (OR) or mean difference comparing alcohol-associated HCC and other causes was obtained with pairwise meta-analysis. Survival outcomes were evaluated using a pooled analysis of hazard ratios. RESULTS: Of 4,824 records identified, 55 articles (86,345 patients) were included. Overall, 30.4% (CI: 24.0%-37.7%) of HCC were alcohol-associated, with the highest proportion in Europe and the lowest in the Americas. People with alcohol-associated HCC were more likely male, but similar in age and comorbidities, compared to other causes. 20.8% (CI: 11.4%-34.9%) of people with alcohol-associated HCC underwent surveillance compared to 35.0%, 31.6%, and 21.4% in hepatitis B virus, hepatitis C virus, and metabolic dysfunction-associated HCC, respectively (all P<0.05). Alcohol-associated HCC had a lower likelihood of BCLC stage (0/A) (OR: 0.7, CI: 0.6-0.9; P=0.018) and curative therapy (24.5% vs 33.9%; OR 0.7, CI: 0.5-0.9; P=0.003), and higher mortality (HR: 1.3, CI: 1.1-1.5, P=0.012) when compared to other causes. CONCLUSIONS: Alcohol-associated HCC is associated with lower surveillance rates, more advanced BCLC stage, lower likelihood of receiving curative therapy, and poorer survival. These data call for measures to reduce heavy alcohol consumption and improve strategies for effective HCC surveillance in high-risk individuals.

The Burden of Overweight and Obesity-Associated Gastrointestinal Cancers in Low and Lower-Middle-Income Countries: A Global Burden of Disease 2019 Analysis.

INTRODUCTION: Obesity is associated with cancer, including gastrointestinal (GI). Data from low (LICs) and lower-middle-income countries (MICs) are limited. METHODS: We utilized data from the Global Burden of Disease Study 2019 to determine the mortality from GI cancer risk of high body mass index (BMI) in these countries. RESULTS: Mortality rates of GI cancers from high BMI increased in LICs and lower MICs, while burdens decreased or remained stable in high and middle-income countries. DISCUSSION: The GI cancer-related burden from high BMI increased in LICs and lower MICs, necessitating a concerted effort to tackle the obesity pandemic.

From Shadows to Spotlight: Exploring the Escalating Burden of Alcohol-Associated Liver Disease and Alcohol Use Disorder in Young Women.

INTRODUCTION: The burden of alcohol-related complications is considerable, particularly alcohol-associated liver disease and alcohol use disorder (AUD). However, there are deficiencies in comprehensive epidemiological research focusing on these issues, especially among young women who display higher susceptibility to such complications compared with their male counterparts. We thus aimed to determine the global burden of these conditions in this vulnerable group. METHODS: Leveraging data from the Global Burden of Disease Study 2019, we analyzed the prevalence, mortality, and disability-adjusted life years of alcohol-associated cirrhosis (AC), liver cancer from alcohol, and AUD in young women. The findings were categorized by region, nation, and sociodemographic index. RESULTS: The highest age-standardized prevalence rates were observed in AUD (895.96 [95% uncertainty interval (UI) 722.6-1,103.58]), followed by AC (65.33 [95% UI 48.37-86.49]) and liver cancer from alcohol (0.13 [95% UI 0.09-0.19]) per 100,000 people. The highest age-standardized mortality rates were observed in AC (0.75 [95% UI 0.55-0.97]), followed by AUD (0.48 [95% UI 0.43-0.53]) and liver cancer from alcohol (0.06 [95% UI 0.04-0.09]). The highest burdens of AC and AUD were observed in Central Europe, whereas the high-income Asia Pacific had the highest burden of liver cancer from alcohol. DISCUSSION: Throughout the past decade, the trend of AUD varied among regions while the impact of alcohol-associated liver disease has increased, requiring urgent public health strategy to mitigate these complications, particularly in female patients in Europe and the Asia-Pacific region.

The incidence of adverse outcome in donors after living donor liver transplantation: A meta-analysis of 60,829 donors.

The scarcity of liver grafts has prompted developments in living donor liver transplantations (LDLT), with previous literature illustrating similar outcomes in recipients compared to deceased donor transplants. However, significant concerns regarding living donor morbidity and mortality have yet to be examined comprehensively. This study aims to provide estimates of the incidence of various outcomes in living liver donors. In this meta-analysis, Medline and Embase were searched from inception to July 2022 for articles assessing the incidence of outcomes in LDLT donors. Complications in the included studies were classified into respective organ systems. Analysis of incidence was conducted using a generalized linear mixed model with Clopper-Pearson intervals. Eighty-seven articles involving 60,829 living liver donors were included. The overall pooled incidence of complications in LDLT donors was 24.7% (CI: 21.6%-28.1%). The incidence of minor complications was 17.3% (CI: 14.7%-20.3%), while the incidence of major complications was lower at 5.5% (CI: 4.5%-6.7%). The overall incidence of donor mortality was 0.06% (CI: 0.0%-0.1%) in 49,027 individuals. Psychological complications (7.6%, CI: 4.9%-11.5%) were the most common among LDLT donors, followed by wound-related (5.2%, CI: 4.4%-6.2%) and respiratory complications (4.9%, CI: 3.8%-6.3%). Conversely, cardiovascular complications had the lowest incidence among the subgroups at 0.8% (CI: 0.4%-1.3%). This study presents the incidence of post-LDLT outcomes in living liver donors, illustrating significant psychological, wound-related, and respiratory complications. While significant advancements in recent decades have contributed towards decreased morbidity in living donors, our findings call for targeted measures and continued efforts to ensure the safety and quality of life of liver donors post-LDLT.

Associations between metabolic hyperferritinaemia, fibrosis-promoting alleles and clinical outcomes in steatotic liver disease.

BACKGROUND & AIMS: Ferritin has been investigated as a biomarker for liver fibrosis and iron in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). However, whether metabolic hyperferritinaemia predicts progression of liver disease remains unknown. In this study, we sought to understand associations between hyperferritinaemia and (1) adverse clinical outcomes and (2) common genetic variants related to iron metabolism and liver fibrosis. METHODS: This was a retrospective analysis of adults with MASLD seen at the University of Michigan Health System, where MASLD was defined by hepatic steatosis on imaging, biopsy or vibration-controlled transient elastography, plus metabolic risk factors in the absence of chronic liver diseases other than hemochromatosis. The primary predictor was serum ferritin level, which was dichotomized based on a cut-off of 300 or 450 mcg/L for women or men. Primary outcomes included (1) incident cirrhosis, liver-related events, congestive heart failure (CHF), and mortality and (2) distribution of common genetic variants associated with hepatic fibrosis and hereditary hemochromatosis. RESULTS: Of 7333 patients with MASLD, 1468 (20%) had elevated ferritin. In multivariate analysis, ferritinaemia was associated with increased mortality (HR 1.68 [1.35-2.09], p < .001) and incident liver-related events (HR 1.92 [1.11-3.32], p = .019). Furthermore, elevated ferritin was associated with carriage of cirrhosis-promoting alleles including PNPLA3-rs738409-G allele (p = .0068) and TM6SF2-rs58542926-T allele (p = 0.0083) but not with common HFE mutations. CONCLUSIONS: In MASLD patients, metabolic hyperferritinaemia was associated with increased mortality and higher incidence of liver-related events, and cirrhosis-promoting alleles but not with iron overload-promoting HFE mutations.

Disparities among ethnic groups in mortality and outcomes among adults with MASLD: A multicenter study.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the leading cause of chronic liver disease and 10%-20% occurs in lean individuals. There is little data in the literature regarding outcomes in an ethnically-diverse patient populations with MASLD. Thus, we aim to investigate the natural history and ethnic disparities of MASLD patients in a diverse population, and stratified by body mass index categories. METHODS: We conducted a retrospective multicenter study on patients with MASLD at the Banner Health System from 2012 to 2022. Main outcomes included mortality and incidence of cirrhosis, cardiovascular disease, diabetes mellitus (DM), liver-related events (LREs), and cancer. We used competing risk and Cox proportional hazard regression analysis for outcome modelling. RESULTS: A total of 51 452 (cross-sectional cohort) and 37 027 (longitudinal cohort) patients were identified with 9.6% lean. The cohort was 63.33% European ancestry, 27.96% Hispanic ancestry, 3.45% African ancestry, and 2.31% Native American/Alaskan ancestry. Median follow-up was 45.8 months. After adjusting for confounders, compared to European individuals, Hispanic and Native American/Alaskan patients had higher prevalence of cirrhosis and DM, and individuals of Hispanic, African, and Native American/Alaskan ancestry had higher mortality and incidence of LREs and DM. Lean patients had higher mortality and incidence of LREs compared with non-lean patients. CONCLUSION: Native American/Alaskan, Hispanic, and African patients had higher mortality and incidence of LREs and DM compared with European patients. Further studies to explore the underlying disparities and intervention to prevent LREs in lean patients, particularly several ethnic groups, may improve clinical outcomes.

The prevalence and predictors of metabolic dysfunction-associated steatotic liver disease and fibrosis/cirrhosis among adolescents/young adults.

OBJECTIVES: We investigated the current prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and fibrosis/cirrhosis and identified at-risk populations for MASLD and MASLD-related fibrosis among US adolescents and young adults in the United States. METHODS: Utilizing the National Health and Nutrition Examination Survey 2017-2020, the prevalence of MASLD and fibrosis/cirrhosis was assessed via controlled attenuation parameter (CAP) score and liver stiffness measurements by transient elastography in participants aged 12-29 years with at least one cardiometabolic criteria and absence of other chronic liver disease. Multivariable logistic regression was performed to determine predictors of MASLD and MASLD-related fibrosis. RESULTS: The overall prevalence of MASLD was 23.9% (95% confidence interval [CI]: 21.3-26.5 for CAP ≥ 263 dB/m) and 17.3% (95% CI: 14.7-20.0 for ≥285 dB/m), respectively. The prevalence of fibrosis and cirrhosis in MASLD was 11.0% and 3.1%, respectively. When categorized by age, the prevalence of MASLD varied from 16.8% (of which 6.2% [fibrosis], 1.8% [cirrhosis]) in early and middle adolescents (12-17 years), to 25.5% (11.8% [fibrosis], 4.8% [cirrhosis]) in late adolescents and young adults (18-24 years), and to 30.4% (of which 13.2% [fibrosis] and 2.1% [cirrhosis]) in older young adults (25-29 years). The independent predictors for MASLD included male sex, Hispanic, non-Hispanic Asian, body mass index, and low HDL-cholesterol. In contrast, diabetes and body mass index were associated with an increased risk of fibrosis in individuals with MASLD. CONCLUSIONS: The prevalence of MASLD and related fibrosis in adolescents and young adults in the United States has reached a significant level, with a substantial proportion of cirrhosis.

Estimated pulse wave velocity in metabolic dysfunction-associated steatotic liver disease and all-cause/cause-specific mortality.

BACKGROUND AND AIM: Several reports show a significant association between metabolic dysfunction-associated steatotic liver disease (MASLD) and arterial stiffness (estimated pulse wave velocity [ePWV]) as a surrogate marker of vascular age. We investigate whether ePWV as arterial stiffness in MASLD is associated with all-cause/cause-specific mortality. METHODS: This cohort study was based on the third National Health and Nutrition Examination Survey (NHANES, 1988-1994) and NHANES 2007-2014 and linked mortality datasets through 2019. Cox regression models assessed the association between ePWV categorized by quartile and all-cause/cause-specific mortality among individuals with MASLD. RESULTS: During the follow-up of a median of 26.3 years (interquartile range: 19.9-27.9), higher levels of ePWV among individuals with MASLD were associated with increased all-cause mortality, which remained significant after adjusting for demographic, lifestyle, clinical, and metabolic risk factors. Furthermore, higher ePWV in MASLD was associated with higher cardiovascular mortality. There was a 44% (hazard ratio: 1.44, 95% confidence interval: 1.32-1.58) increase in all-cause mortality and a 53% (hazard ratio: 1.53, 95% confidence interval: 1.32-1.77) increase in cardiovascular mortality for every 1 m/s increase in ePWV in MASLD. However, there was no significant association between ePWV and cancer-related mortality. Sensitivity analyses using the NHANES 2007-2014 dataset showed results identical to the original analysis. CONCLUSION: Higher ePWV in MASLD was associated with a higher risk of all-cause and cardiovascular mortality beyond traditional cardiovascular risk factors. Screening for ePWV in individuals with MASLD may be an effective and beneficial approach to reducing all-cause and cardiovascular mortality.

Global epidemiology of early-onset upper gastrointestinal cancer: trend from the Global Burden of Disease Study 2019.

BACKGROUND AND AIM: In recent years, there has been a growing incidence of gastrointestinal cancer in young individuals. Despite its significant morbidity and mortality, research on upper gastrointestinal (UGI) cancer in young populations has been relatively limited. Therefore, studies on the epidemiological changes of this cancer are needed. METHODS: Using data from the Global Burden of Disease Study 2019, we examined the incidence, death, and disability-adjusted life years (DALYs) from UGI cancers in the young, namely, early-onset esophageal cancer (EOEC) and early-onset gastric cancer (EOGC). These results were stratified by sex, geographical region, country, and sociodemographic index. RESULTS: There was a total of 185 140 cases, 120 289 deaths, and 5.70 million DALYs attributable to early-onset UGI cancers globally. From 2010 to 2019, the global incidence, death, and DALYs rates of early-onset UGI cancers decreased. In contrast, the incidence rates increased in both EOEC (+1.15%) and EOGC (+0.21%) in the Eastern Mediterranean region. CONCLUSIONS: Over the past decade, the burden of UGI cancer in the young has decreased. However, it has increased in the Eastern Mediterranean region. Further research to elucidate the attributable risk factors in this population is warranted.

Proton Pump Inhibitors Increases Longitudinal Risk of Mortality, Decompensation, and Infection in Cirrhosis: A Meta-Analysis.

BACKGROUND/AIMS: Proton pump inhibitors (PPIs) are frequently prescribed to cirrhotic patients, but there is limited longitudinal evidence regarding their effects. This study aimed to assess the impact of PPIs on adverse events in cirrhotic patients. METHODS: A comprehensive search was conducted using the Medline and Embase databases to identify relevant articles. Pooled hazard ratios (HRs) using DerSimonian and Laird random-effects model were calculated to evaluate the risk of adverse events such as long-term mortality, hepatic decompensation, hepatic encephalopathy (HE), spontaneous bacterial peritonitis (SBP), and overall infection in cirrhotic patients with PPI use. RESULTS: The analysis included 28 studies with 260,854 cirrhotic patients. The prevalence of PPI use among cirrhotic patients was 55.93%. The use of PPIs was not significantly associated with short-term mortality in cirrhotic patients. However, long-term mortality (HR 1.321, 95% CI 1.103-1.581, P = 0.002), decompensation (HR 1.646, 95% CI 1.477-1.835, P < 0.001), HE (HR 1.968, 95% CI 1.372-2.822, P < 0.001), SBP (HR 1.751, 95% CI 1.649-1.859, P < 0.001), and infection (HR 1.370, 95% CI 1.148-1.634, P < 0.001) were significantly associated with PPI use. Sensitivity analysis with prospective studies yielded similar results. CONCLUSION: PPIs should be reserved for appropriate indications at lowest effective dose for cirrhotic patients due to the potential harm.

Sex and Race-Ethnic Disparities in Metabolic Dysfunction-Associated Steatotic Liver Disease: An Analysis of 40,166 Individuals.

BACKGROUND: To overcome the limitations of the term "non-alcoholic fatty liver disease" (NAFLD), the term metabolic-associated steatotic liver disease (MASLD) was introduced. While epidemiologic studies have been conducted on MASLD, there is limited evidence on its associated sex and ethnic variations. AIMS: This study assesses the differences across sex and race-ethnicity on the prevalence, associated risk factors and adverse outcomes in individuals with MASLD. METHODS: Data retrieved from the National Health and Nutrition Examination Survey between 1999 to 2018 was analyzed. Prevalence, clinical characteristics, and outcomes were evaluated according to sex and race-ethnicity. Adverse outcomes and mortality events were analyzed using multivariate analyses. RESULTS: Of 40,166 individuals included, 37.63% had MASLD. There was a significant increase in MASLD prevalence from 1999 to 2018 among Mexican Americans (Annual Percentage Change [APC] + 1.889%, p < 0.001), other Hispanics (APC + 1.661%, p = 0.013), NH Whites (APC + 1.084%, p = 0.018), NH Blacks (APC + 1.108%, p = 0.007), and females (APC + 0.879%, p = 0.030), but not males. Females with MASLD were at lower risk of all-cause (HR: 0.766, 95%CI 0.711 to 0.825, p < 0.001), cardiovascular disease-related (CVD) (SHR: 0.802, 95% CI 0.698 to 0.922, p = 0.002) and cancer-related mortality (SHR: 0.760, 95% CI 0.662 to 0.873, p < 0.001). Significantly, NH Blacks have the highest risk of all-cause and CVD-related mortality followed by NH Whites then Mexican Americans. CONCLUSION: There has been an increase in prevalence in most race-ethnicities over time. While the change in definition shows no significant differences in previous associations found in NAFLD, the increased mortality in NH Whites relative to Mexican Americans remains to be explored.

Global prevalence of non-alcoholic fatty liver disease in type 2 diabetes mellitus: an updated systematic review and meta-analysis.

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease, with type 2 diabetes mellitus (T2DM) as a major predictor. Insulin resistance and chronic inflammation are key pathways in the pathogenesis of T2DM leading to NAFLD and vice versa, with the synergistic effect of NAFLD and T2DM increasing morbidity and mortality risks. This meta-analysis aims to quantify the prevalence of NAFLD and the prevalence of clinically significant and advanced fibrosis in people with T2DM. METHODS: MEDLINE and Embase databases were searched from inception until 13 February 2023. The primary outcomes were the prevalence of NAFLD, non-alcoholic steatohepatitis (NASH) and fibrosis in people with T2DM. A generalised linear mixed model with Clopper-Pearson intervals was used for the analysis of proportions with sensitivity analysis conducted to explore heterogeneity between studies. RESULTS: 156 studies met the inclusion criteria, and a pooled analysis of 1 832 125 patients determined that the prevalence rates of NAFLD and NASH in T2DM were 65.04% (95% CI 61.79% to 68.15%, I2=99.90%) and 31.55% (95% CI 17.12% to 50.70%, I2=97.70%), respectively. 35.54% (95% CI 19.56% to 55.56%, I2=100.00%) of individuals with T2DM with NAFLD had clinically significant fibrosis (F2-F4), while 14.95% (95% CI 11.03% to 19.95%, I2=99.00%) had advanced fibrosis (F3-F4). CONCLUSION: This study determined a high prevalence of NAFLD, NASH and fibrosis in people with T2DM. Increased efforts are required to prevent T2DM to combat the rising burden of NAFLD. PROSPERO REGISTRATION NUMBER: CRD42022360251.

Ethnic disparities in waitlist outcomes of patients with nonalcoholic steatohepatitis listed for liver transplantation in the US.

NASH is the fastest-growing cause of liver cirrhosis and is the leading indication for liver transplantation (LT). However, significant racial and ethnic disparities in waitlist outcomes and LT allocation may unfairly disadvantage minorities. Our aim was to characterize racial and ethnic disparities in waitlist mortality and transplantation probability among patients with NASH. This is a retrospective analysis of the United Network for Organ Sharing registry data of LT candidates from January 1, 2000 to December 31, 2021. Outcomes analysis was performed using competing risk analysis with the Fine and Gray model. The multivariable adjustment was conducted, and mixed-effect regression was used to compare the model for end-stage liver disease scores at listing and removal. Of 18,562 patients with NASH cirrhosis, there were 14,834 non-Hispanic Whites, 349 African Americans, 2798 Hispanics, 312 Asians, and 269 of other races/ethnicities; African American (effect size: 2.307, 95% CI: 1.561-3.053, and p < 0.001) and Hispanic (effect size: 0.332, 95% CI: 0.028-0.637, p = 0.032) patients were found to have a significantly higher model for end-stage liver disease scores at the time of listing than non-Hispanic Whites. African Americans had a higher probability of receiving LT relative to non-Hispanic Whites (subdistribution HR: 1.211, 95% CI: 1.051-1.396, and p = 0.008). However, Hispanic race/ethnicity was associated with a lower transplantation probability (subdistribution HR: 0.793, 95% CI: 0.747-0.842, and p < 0.001) and increased waitlist mortality (subdistribution HR: 1.173, CI: 1.052-1.308, and p = 0.004) compared with non-Hispanic Whites. There are significant racial and ethnic disparities in waitlist outcomes of patients with NASH in the US. Hispanic patients are less likely to receive LT and more likely to die while on the waitlist compared with non-Hispanic Whites despite being listed with a lower model for end-stage liver disease scores.

Rising incidence and impact of early-onset colorectal cancer in the Asia-Pacific with higher mortality in females from Southeast Asia: a global burden analysis from 2010 to 2019.

BACKGROUND AND AIM: Early-onset colorectal cancer (CRC) is a growing global health concern, especially in the Asia-Pacific region. However, comprehensive research on this topic from the region is lacking. Our study aims to investigate trends in early-onset CRC in Asia over 10 years, filling this research gap. METHODS: This study utilized data from the Global Burden of Disease Study 2019 to assess temporal trends in early-onset CRC in the Asia-Pacific. The analysis included estimating annual frequencies and age-standardized rates (ASRs) of early-onset CRC incidence, death, and disability-adjusted life-years (DALYs) by gender. RESULTS: The incidence of early-onset CRC significantly increased in both regions with higher increase and in the Western Pacific region. Notable increases were observed among males in the Western Pacific and females in Southeast Asia (SEA). Mortality rates remained stable in the Western Pacific but increased by 10.6% in SEA, especially among females. DALYs due to CRC also increased significantly in SEA, with a greater rise among females. The Western Pacific had the highest CRC incidence, and in SEA, the mortality rate was higher in females than males. CONCLUSIONS: Our study reveals a substantial increase in early-onset CRC in the Asia-Pacific underscoring the urgency for effective interventions. Thus, a comprehensive approach comprising controlled risk reduction, health promotion to heightened disease awareness, and implementation of effective screening strategies should be executed timely to mitigate the burden of early-onset CRC.

Fibrosis-4 Index Score Predicts Concomitant Coronary Artery Diseases Across the Spectrum of Fatty Liver Disease.

BACKGROUND: 25% of US adults have nonalcoholic fatty liver disease (NAFLD). The independent association between hepatic fibrosis and cardiovascular disease remains controversial. Metabolic dysfunction-associated fatty liver disease (MAFLD) precisely characterizes hepatic steatosis. AIM: We aimed to determine if degree of hepatic fibrosis, with differing metabolic risk factors, is associated with presence of coronary artery disease (CAD). METHODS: Retrospective review of patients with hepatic steatosis at a single center from January 2016-October 2020 was performed. MAFLD diagnosis was based on presence of fatty liver disease and metabolic factors. Descriptive statistics and stepwise multivariable logistic regression were performed. RESULTS: 5288 patients with hepatic steatosis were included. 2821 patients with steatosis and metabolic risks were classified as NAFLD-MAFLD. 1245 patients with steatosis without metabolic risks were classified as non-MAFLD NAFLD. 812 patients with metabolic risks and other liver disease and were classified as non-NAFLD MAFLD. On Multivariate analysis, Fib-4 ≥ 2.67 was an independent risk factor for CAD in the overall fatty liver disease and NAFLD-MAFLD groups. Fib-4 as a continuous variable showed linear association with CAD risk in the overall fatty liver disease, Non-MAFLD NAFLD and NAFLD-MAFLD groups, at Fib-4 values below 2.67. CONCLUSION: Fib-4 ≥ 2.67 is independently predicts concomitant CAD in patients with hepatic steatosis. Fib-4, at levels below 2.67, is significantly associated with concomitant CAD in the all fatty liver disease, Non-MAFLD NAFLD, and NAFLD-MAFLD groups. Emphasizing clinical phenotypes and Fib-4 levels may help target those with an increased risk for CAD.

Outcomes following liver transplantation from HCV-seropositive donors to HCV-seronegative recipients.

BACKGROUND & AIMS: Grafts from HCV-seropositive donors can now be considered for liver transplantation (LT) owing to the advent of direct-acting antivirals (DAAs). We report on our multicenter experience of transplanting liver grafts from HCV-seropositive donors into HCV-seronegative recipients. METHODS: This is a prospective multicenter observational study evaluating outcomes in adult HCV-seronegative LT recipients who received grafts from HCV-seropositive donors in 3 US centers. RESULTS: From 01/18 to 09/19, 34 HCV-seronegative LT recipients received grafts from HCV-seropositive donors (20 HCV-viremic and 14 non-viremic). Seven grafts were from cardiac-dead donors. The median MELD-Na score at allocation was 20. Six recipients underwent simultaneous liver-kidney transplant and 4 repeat LT. No recipient of an HCV-non-viremic graft developed HCV viremia. All 20 patients who received HCV-viremic grafts had HCV viremia confirmed within 3 days after LT. DAA treatment was started at a median of 27.5 days after LT. Median pre-treatment viral load was 723,000 IU/ml. All (20/20) patients completed treatment and achieved SVR12. Treatment was well tolerated with minimal adverse events. One patient developed HCV-related acute membranous nephropathy that resulted in end-stage kidney disease, despite achieving viral clearance. This patient died due to presumed infectious complications. A recipient of an HCV-non-viremic graft died with acute myocardial infarction 610 days post LT. CONCLUSIONS: Transplantation of liver grafts from HCV-seropositive donors into HCV-seronegative recipients resulted in excellent short-term outcomes. Antiviral therapy was effective and well tolerated. Careful ongoing assessment and prompt initiation of antiviral therapy are recommended. Longer term follow-up in carefully conducted clinical trials is still required to confirm these results. LAY SUMMARY: This study shows that livers from donors exposed to HCV expand the donor pool and can be used safely in patients who are seronegative for hepatitis C infection. Treatment, initiated early post transplantation, is effective and resulted in cure in all patients.

PNPLA3 Gene Polymorphism and Liver- and Extrahepatic Cancer-Related Mortality in the United States.

The palatin-like phospholipase domain-containing 3 (PNPLA3) rs738409 G allele is associated with nonalcoholic fatty liver disease (NAFLD), hepatocellular carcinoma,1 and all-cause or cardiovascular mortality in the general population.2 One recent Italian study reported an association between PNPLA3 polymorphism and liver-related events and mortality in biopsy-confirmed NAFLD.3 Regarding extrahepatic cancer-related mortality, one study showed that only women carrying the G allele without hepatic steatosis had a 60% lower risk for cancer-related mortality.4 However, owing to insufficient follow-up and selected populations, the results from these studies cannot generalize about the association between PNPLA3 polymorphism and liver- and extrahepatic cancer-related mortality at a population level. Thus, we investigated the association between PNPLA3 polymorphism and liver- and extrahepatic cancer-related mortality based on the presence of NAFLD in the U.S. general population.
