Nuclear magnetic resonance (NMR)-based plasma fatty acids are objective biomarkers of many diseases. Herein, we aim to explore the associations of NMR-based plasma fatty acids with the risk of hepatocellular carcinoma (HCC) and chronic liver disease (CLD) mortality in 252,398 UK Biobank participants. Here we show plasma levels of n-3 poly-unsaturated fatty acids (PUFA) and n-6 PUFA are negatively associated with the risk of incident HCC [HRQ4vsQ1: 0.48 (95% CI: 0.33-0.69) and 0.48 (95% CI: 0.28-0.81), respectively] and CLD mortality [HRQ4vsQ1: 0.21 (95% CI: 0.13-0.33) and 0.15 (95% CI: 0.08-0.30), respectively], whereas plasma levels of saturated fatty acids are positively associated with these outcomes [HRQ4vsQ1: 3.55 (95% CI: 2.25-5.61) for HCC and 6.34 (95% CI: 3.68-10.92) for CLD mortality]. Furthermore, fibrosis stage significantly modifies the associations between PUFA and CLD mortality. This study contributes to the limited prospective evidence on the associations between plasma-specific fatty acids and end-stage liver outcomes.

Sepsis-Associated Liver Injury (SALI) is an independent risk factor for death from sepsis. The aim of this study was to develop an interpretable machine learning model for early prediction of 28-day mortality in patients with SALI. Data from the Medical Information Mart for Intensive Care (MIMIC-IV, v2.2, MIMIC-III, v1.4) were used in this study. The study cohort from MIMIC-IV was randomized to the training set (0.7) and the internal validation set (0.3), with MIMIC-III (2001 to 2008) as external validation. The features with more than 20% missing values were deleted and the remaining features were multiple interpolated. Lasso-CV that lasso linear model with iterative fitting along a regularization path in which the best model is selected by cross-validation was used to select important features for model development. Eight machine learning models including Random Forest (RF), Logistic Regression, Decision Tree, Extreme Gradient Boost (XGBoost), K Nearest Neighbor, Support Vector Machine, Generalized Linear Models in which the best model is selected by cross-validation (CV_glmnet), and Linear Discriminant Analysis (LDA) were developed. Shapley additive interpretation (SHAP) was used to improve the interpretability of the optimal model. At last, a total of 1043 patients were included, of whom 710 were from MIMIC-IV and 333 from MIMIC-III. Twenty-four clinically relevant parameters were selected for model construction. For the prediction of 28-day mortality of SALI in the internal validation set, the area under the curve (AUC (95% CI)) of RF was 0.79 (95% CI: 0.73-0.86), and which performed the best. Compared with the traditional disease severity scores including Oxford Acute Severity of Illness Score (OASIS), Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score II (SAPS II), Logistic Organ Dysfunction Score (LODS), Systemic Inflammatory Response Syndrome (SIRS), and Acute Physiology Score III (APS III), RF also had the best performance. SHAP analysis found that Urine output, Charlson Comorbidity Index (CCI), minimal Glasgow Coma Scale (GCS_min), blood urea nitrogen (BUN) and admission_age were the five most important features affecting RF model. Therefore, RF has good predictive ability for 28-day mortality prediction in SALI. Urine output, CCI, GCS_min, BUN and age at admission(admission_age) within 24 h after intensive care unit(ICU) admission contribute significantly to model prediction.

INTRODUCTION: Patients with intestinal failure (IF) are often dependent on PN for provision of calories and nutrients for survival. Similar to chronic intestinal failure (CIF) patients, those who have AIF are also at risk of IFALD, which is a poorly understood but potentially fatal condition. The local incidence of IFALD amongst AIF patients is not known. OBJECTIVES: The primary objective of this study was to determine the incidence of IFALD in AIF patients on short-term PN. Secondary objectives were to analyse patient and PN risk factors of IFALD, and clinical outcomes of length of stay (LOS) and inpatient mortality. DESIGN: This was a retrospective cross-sectional cohort study of hospitalised adult patients with AIF prescribed with short-term PN. All adult patients aged 21 years and above who received PN for at least 5 consecutive days and had normal liver function tests (LFTs) at the time of PN initiation were included in this study. RESULTS: A total of 171 patients were enrolled in this study, with 77 (45%) having deranged LFTs at the end of PN therapy and categorised under the IFLAD group. The patient cohort was predominantly male (92 [54%]) and had a median age of 68 years (IQR 59-76). Patients with IFALD at the end of PN therapy had higher diabetes prevalence (36% vs 26%, p = 0.2) and were on PN for a longer duration (median [IQR]: 12 [8-17] vs 8 [6-15] days, p = 0.003) than those without IFALD. There were no significant differences in patient and PN characteristics between the IFLAD and non-IFALD group. The multivariable models showed that the IFALD cohort had longer hospital stays (HR 0.90, 95% CI 0.65-1.23) and lower odds of inpatient death (OR 0.75, 95% CI 0.12-4.60), though both findings are not statistically significant (p = 0.5, 0.7). CONCLUSION: In this study, IFALD is a common phenomenon in AIF and the incidence was found to be an estimated 50% amongst patients on short-term PN with similar clinical outcomes between the two groups.

BACKGROUND AND AIMS: The prognostic performance of von Willebrand factor (VWF) may vary across clinical stages of advanced chronic liver disease (ACLD). Therefore, we investigated the evolution of VWF and other biomarkers throughout the full ACLD spectrum and evaluated their stage-specific prognostic utility. METHODS: We retrospectively included Viennese ACLD patients with available information on hepatic venous pressure gradient (HVPG), C-reactive protein (CRP)/VWF levels and outcomes. ACLD stages were defined according to D'Amico et al. We included an external validation cohort from Padua. RESULTS: We observed gradual increases in VWF throughout ACLD stages. In contrast, HVPG levelled off in decompensated ACLD (dACLD), whereas MELD showed only minor changes in the early stages and CRP did not increase until stage 3. VWF was associated with hepatic decompensation/liver-related death in compensated ACLD (cACLD) in a fully adjusted model, while it was not independently predictive of ACLF/liver-related death in dACLD. After backward selection, HVPG/CRP/VWF remained the main predictors of hepatic decompensation/liver-related death in cACLD. Notably, the performance of the non-invasive CRP/VWF-based model was comparable to invasive HVPG-based models (C-index:0.765 ± 0.034 vs. 0.756 ± 0.040). The discriminative ability of the CRP/VWF-based model was confirmed in an external validation cohort using another VWF assay which yielded systematically lower values. CONCLUSION: VWF is the only biomarker that gradually increases across all ACLD stages. It is of particular prognostic value in cACLD, where a CRP/VWF-based model is equivalent to an invasive HVPG-based model. Systematic differences in VWF underline the importance of interlaboratory surveys. Moreover, our findings reinforce the notion that, already in cACLD, inflammation is a key disease-driving mechanism.

BACKGROUND: Patients with liver disease undergoing colectomy have higher rates of complications and mortality. The Albumin-Bilirubin score is a recently developed system, established to predict outcomes after hepatectomy, that accounts for liver dysfunction. METHODS: All patients undergoing colectomy were identified in the 2015-2018 American College of Surgeons National Surgical Quality Improvement Program colectomy-targeted database. Demographics and outcomes were compared between patients with Albumin-Bilirubin Grade 1 vs. 2/3. Multivariable regression was performed for outcomes including colorectal-specific complications. Areas under the receiver operative characteristic curves were calculated to determine accuracy of the Albumin-Bilirubin score. RESULTS: Of 86,273 patients identified, 48% (N = 41,624) were Albumin-Bilirubin Grade 1, 45% (N = 38,370) Grade 2 and 7% (N = 6,279) Grade 3. Patents with Grade 2/3 compared to Grade 1 had significantly increased mortality (7.2% vs. 0.9%, p < 0.001) and serious morbidity (31% vs. 12%, p < 0.001). Colorectal-specific complications including anastomotic leak (3.7% vs. 2.8%, p < 0.001) and prolonged ileus (26% vs. 14%, p < 0.001) were higher in patients with Grade 2/3. Grade 2/3 had increased risk of mortality (odds ratio 3.07, p < 0.001) and serious morbidity (1.78, p < 0.001). Albumin-Bilirubin had excellent accuracy in predicting mortality (area under the curve 0.81, p < 0.001) and serious morbidity (0.70, p < 0.001). CONCLUSION: Albumin-Bilirubin is easily calculated using only serum albumin and total bilirubin values. Grade 2/3 is associated with increased rates of mortality and morbidity following colectomy. Albumin-Bilirubin can be applied to risk-stratify patients prior to colectomy.

Importance: Approximately 65% of adults in the US consume sugar-sweetened beverages daily. Objective: To study the associations between intake of sugar-sweetened beverages, artificially sweetened beverages, and incidence of liver cancer and chronic liver disease mortality. Design, Setting, and Participants: A prospective cohort with 98 786 postmenopausal women aged 50 to 79 years enrolled in the Women's Health Initiative from 1993 to 1998 at 40 clinical centers in the US and were followed up to March 1, 2020. Exposures: Sugar-sweetened beverage intake was assessed based on a food frequency questionnaire administered at baseline and defined as the sum of regular soft drinks and fruit drinks (not including fruit juice); artificially sweetened beverage intake was measured at 3-year follow-up. Main Outcomes and Measures: The primary outcomes were (1) liver cancer incidence, and (2) mortality due to chronic liver disease, defined as death from nonalcoholic fatty liver disease, liver fibrosis, cirrhosis, alcoholic liver diseases, and chronic hepatitis. Cox proportional hazards regression models were used to estimate multivariable hazard ratios (HRs) and 95% CIs for liver cancer incidence and for chronic liver disease mortality, adjusting for potential confounders including demographics and lifestyle factors. Results: During a median follow-up of 20.9 years, 207 women developed liver cancer and 148 died from chronic liver disease. At baseline, 6.8% of women consumed 1 or more sugar-sweetened beverage servings per day, and 13.1% consumed 1 or more artificially sweetened beverage servings per day at 3-year follow-up. Compared with intake of 3 or fewer servings of sugar-sweetened beverages per month, those who consumed 1 or more servings per day had a significantly higher risk of liver cancer (18.0 vs 10.3 per 100 000 person-years [P value for trend = .02]; adjusted HR, 1.85 [95% CI, 1.16-2.96]; P = .01) and chronic liver disease mortality (17.7 vs 7.1 per 100 000 person-years [P value for trend <.001]; adjusted HR, 1.68 [95% CI, 1.03-2.75]; P = .04). Compared with intake of 3 or fewer artificially sweetened beverages per month, individuals who consumed 1 or more artificially sweetened beverages per day did not have significantly increased incidence of liver cancer (11.8 vs 10.2 per 100 000 person-years [P value for trend = .70]; adjusted HR, 1.17 [95% CI, 0.70-1.94]; P = .55) or chronic liver disease mortality (7.1 vs 5.3 per 100 000 person-years [P value for trend = .32]; adjusted HR, 0.95 [95% CI, 0.49-1.84]; P = .88). Conclusions and Relevance: In postmenopausal women, compared with consuming 3 or fewer servings of sugar-sweetened beverages per month, those who consumed 1 or more sugar-sweetened beverages per day had a higher incidence of liver cancer and death from chronic liver disease. Future studies should confirm these findings and identify the biological pathways of these associations.

Mice with deletion of Cyp2c70 have a human-like bile acid composition, display age- and sex-dependent signs of hepatobiliary disease and can be used as a model to study interactions between bile acids and the gut microbiota in cholestatic liver disease. In the present study, we rederived Cyp2c70-/- mice as germ-free (GF) and colonized them with a human or a mouse microbiota to investigate whether the presence of a microbiota can be protective in cholangiopathic liver disease associated with Cyp2c70-deficiency. GF Cyp2c70-/- mice showed reduced neonatal survival, liver fibrosis, and distinct cholangiocyte proliferation. Colonization of germ-free breeding pairs with a human or a mouse microbiota normalized neonatal survival of the offspring, and particularly colonization with mouse microbiota from a conventionally raised mouse improved the liver phenotype at 6-10 weeks of age. The improved liver phenotype in conventionalized (CD) Cyp2c70-/- mice was associated with increased levels of tauro-ursodeoxycholic acid (TUDCA) and UDCA, resulting in a more hydrophilic bile acid profile compared with GF and humanized Cyp2c70-/- mice. The hydrophobicity index of biliary bile acids of CD Cyp2c70-/- mice was associated with changes in gut microbiota, liver weight, liver transaminases, and liver fibrosis. Hence, our results indicate that neonatal survival of Cyp2c70-/- mice seems to depend on the establishment of a gut microbiota at birth, and the improved liver phenotype in CD Cyp2c70-/- mice may be mediated by a larger proportion of TUDCA/UDCA in the circulating bile acid pool and/or by the presence of specific bacteria.

INTRODUCTION: Deaths of despair (i.e., suicide, drug/alcohol overdose, and chronic liver disease and cirrhosis) have been increasing over the past 2 decades. However, no large-scale studies have examined geographic patterns of deaths of despair in the U.S. This ecologic study identifies geographic and temporal patterns of individual and co-occurring clusters of deaths of despair. METHODS: All individuals aged ≥10 years who died in the U.S. between 2000 and 2019 and resided within the 48 contiguous states and Washington, District of Columbia were included (N=2,171,105). Causes of death were limited to deaths of despair, namely suicide, drug/alcohol overdose, and chronic liver disease and cirrhosis. Univariate and multivariate space-time scan statistics were used to identify individual and co-occurring clusters with excess risk of deaths of despair. County-level RRs account for heterogeneity within each cluster. Analyses were conducted from late 2021 to early 2022. RESULTS: Six suicide clusters, four overdose clusters, nine liver disease clusters, and three co-occurring clusters of all three types of deaths were identified. A large portion of the western U.S., southeastern U.S., and Appalachia/rust belt were contained within the co-occurring clusters. The co-occurring clusters had average county RRs ranging from 1.17 (p<0.001) in the southeastern U.S. to 4.90 (p<0.001) in the western U.S. CONCLUSIONS: Findings support identifying and targeting risk factors common to all types of deaths of despair when planning public health interventions. Resources and policies that address all deaths of despair simultaneously may be beneficial for the areas contained within the co-occurring high-risk clusters.

BACKGROUND: To investigate whether liver stiffness (LS) can predict adverse cardiac events in Chinese patients with heart failure (HF). METHODS: A total of 53 hospitalized patients with HF were enrolled, and LS and tricuspid annual plane systolic excursion (TAPSE) were determined with Fibroscan® and echocardiography before discharge. They were divided into two groups: high LS group (LS > 6.9 Kpa, n = 23) and low LS group (LS ≤ 6.9 Kpa, n = 30). Patients were followed up for 24 months at an interval of 3 months. The endpoint of follow-up was death or rehospitalization for HF. RESULTS: All patients were followed up for 24 months or until the endpoint. Patients in the high LS group had lower platelet count (P = 0.014), lower creatine clear rate (P = 0.014), higher level of B-type natriuretic peptide at discharge (P = 0.012), and lower TAPSE (P < 0.001) than those in the low LS group. During 24 months of follow-up, 3 (5.7%) deaths and 21 (39.6%) hospitalizations for HF were observed. Patients in the high LS group had a higher rate of death/rehospitalization than those in the low LS group (Hazard ratio 4.81; 95% confidence interval 1.69-13.7, P = 0.003) after adjustment for age, sex, platelet count, creatine clear rate, and B-type natriuretic peptide level. Moreover, TAPSE ≤ 16 could predict adverse cardiac events with an HR of 6.63 (95% confidence interval 1.69-13.7, P = 0.004) after adjustment for age, sex, platelet count, creatine clear rate, and B-type natriuretic peptide level. CONCLUSION: LS and TAPSE could be used to predict worse outcomes in patients with HF.

BACKGROUND: Postoperative pulmonary complications are a common cause of postoperative morbidity in patients undergoing hepatectomy. This study aimed to identify risk factors, define severity, and evaluate the impact of postoperative pulmonary complications on postoperative morbidity after hepatectomy. METHOD: We used a prospective database in identifying all hepatectomies from 2013 to 2018. The database was then augmented using extensive review of medical records. The Strasburg system was used in categorizing resections per complexity: major hepatic resection and minor hepatic resection, whereas the Clavien-Dindo system was used in defining postoperative pulmonary complications per severity. Potential confounders were controlled for on multiple regression models. RESULTS: A total of 702 cases were identified: major hepatic resection 413 (60%) and minor hepatic resection 289 (40%). Patients demonstrated comparable characteristics, but the postoperative pulmonary complications group was more likely to have chronic obstructive pulmonary disease (10% vs 5%; P = .02). Severe postoperative pulmonary complications among major hepatectomy was observed in 38 patients (13%). Predictors for severe postoperative pulmonary complications requiring intervention included postoperative liver failure (odds ratio = 2.8; P = .002) and biliary fistula (odds ratio = 3.5; P = .001). In addition, the occurrence of severe postoperative pulmonary complications markedly hindered recovery, increasing length of stay by 4.4-fold and readmission rates by 3-fold (P < .001). On multivariable analysis, postoperative pulmonary complications significantly increase postoperative length of stay (8 vs 5 days; P < .001) and readmission (odds ratio = 3.2; P = .001). Mortality was similar (1% vs 4%; P = .066). CONCLUSION: Postoperative pulmonary complications are a major cause of delayed recovery and worse outcomes after hepatectomy. Further, postoperative liver failure and biliary fistula can predict the occurrence of severe postoperative pulmonary complications among major hepatic resection and the associated need for readmission with these complications.

OBJECTIVE: Liver stiffness measurement (LSM) is a tool used to screen for significant fibrosis and portal hypertension. The aim of this retrospective multicentre study was to develop an easy tool using LSM for clinical outcomes in advanced chronic liver disease (ACLD) patients. DESIGN: This international multicentre cohort study included a derivation ACLD patient cohort with valid two-dimensional shear wave elastography (2D-SWE) results. Clinical and laboratory parameters at baseline and during follow-up were recorded. LSM by transient elastography (TE) was also recorded if available. The primary outcome was overall mortality. The secondary outcome was the development of first/further decompensation. RESULTS: After screening 2148 patients (16 centres), 1827 patients (55 years, 62.4% men) were included in the 2D-SWE cohort, with median liver SWE (L-SWE) 11.8 kPa and a model for end stage liver disease (MELD) score of 8. Combination of MELD score and L-SWE predict independently of mortality (AUC 0.8). L-SWE cut-off at ≥20 kPa combined with MELD ≥10 could stratify the risk of mortality and first/further decompensation in ACLD patients. The 2-year mortality and decompensation rates were 36.9% and 61.8%, respectively, in the 305 (18.3%) high-risk patients (with L-SWE ≥20 kPa and MELD ≥10), while in the 944 (56.6%) low-risk patients, these were 1.1% and 3.5%, respectively. Importantly, this M10LS20 algorithm was validated by TE-based LSM and in an additional cohort of 119 patients with valid point shear SWE-LSM. CONCLUSION: The M10LS20 algorithm allows risk stratification of patients with ACLD. Patients with L-SWE ≥20 kPa and MELD ≥10 should be followed closely and receive intensified care, while patients with low risk may be managed at longer intervals.

Physiologic aging leads to attrition of telomeres and replicative senescence. An acceleration of this process has been hypothesized in the progression of chronic liver disease. We sought to examine the association of telomere length (TL) with liver disease and its impact on mortality risk. A cohort of 7,072 adults with leukocyte TL measurements from the National Health and Nutrition Examination Survey 1999-2002 with mortality follow-up through 2015 was analyzed. Liver disease was defined by aminotransferase levels and classified into etiology-based and advanced fibrosis categories. Multivariable-adjusted linear regression models estimated effect sizes, with 95% confidence intervals (CIs), of the presence of liver disease on TL. Cox regression models evaluated associations between TL and all-cause mortality risk using adjusted hazard ratios (HRs). The cohort was representative of the US population with mean age 46.1 years and mean TL 5.79 kilobase pairs. No overall association between TL and liver disease was found; however, there was a significant negative association of TL and advanced liver fibrosis in individuals aged 65 and above. The liver disease cohort (HR 1.22, 95% CI 0.99-1.51) and those with metabolic syndrome (HR 1.26, 95% CI 0.96-1.67) had increased mortality risk with shorter TL. The relationship between TL and all-cause mortality was stronger in women (HR 1.51, 95% CI 1.02-2.23) and in non-Hispanic Whites (HR 1.37, 95% CI 1.02-1.84). Conclusion: Shortened leukocyte TL is independently associated with advanced liver disease at older ages, and with a higher risk of all-cause mortality in those with liver disease. These associations reaffirm the need to better understand the role of telomeres in the progression of liver disease.

Coronavirus disease 2019 (COVID-19) has hampered health care delivery globally. We evaluated the feasibility, outcomes, and safety of telehepatology in delivering quality care amid the pandemic. A telemedicine setup using smartphones by hepatologists was organized at our tertiary-care center after pilot testing. Consecutive patients availing telehepatology services were recruited between March and July 2020. An adapted model for assessment of telemedicine was used after validity and reliability testing, to evaluate services 7-21 days after index teleconsultation. Of the 1,419 registrations, 1,281 (90.3%) consultations were completed. From 245 randomly surveyed patients, 210 (85.7%) responded (age [years, interquartile range]: 46 [35-56]; 32.3% females). Seventy percent of patients belonged to the middle or lower socio-economic class, whereas 61% were from rural areas. Modes of teleconsultation were audio (54.3%) or hybrid video call (45.7%). Teleconsultation alone was deemed suitable in 88.6% of patients. Diagnosis and compliance rates were 94% and 82.4%, respectively. Patients' convenience rate, satisfaction rate, improvement rate, success rate, and net promoter scores were 99.0%, 85.2%, 49.5%, 46.2% and 70, respectively. Physical and mental quality of life improved in 67.1% and 82.8% of patients, respectively, following index teleconsultation. Person-hours and money spent by patients were significantly lower with teleconsultation (P < 0.001); however, person-hours spent by hospital per teleconsultation were higher than in physical outpatient services (P < 0.001). Dissatisfied patients were more likely to have lower diagnosis rate, unsuitability for teleconsultation, noncompliance, poorer understanding, and uncomfortable conversation during teleconsultation. Connectivity issues (22.9%) were the most common barrier. Three patients, all of whom were advised emergency care during teleconsultation, succumbed to their illness. Conclusion: Telehepatology is a feasible and reasonably effective tool for rendering health care services using smartphones during the COVID-19 pandemic. Systematic implementation, possible integration into routine health care delivery, and formal cost-effectiveness of telehepatology services need further exploration.

AIMS: This study seeks to evaluate the association between pre-transplant portal vein thrombosis (PVT) and overall survival, graft failure, waitlist mortality, and post-operative PVT after liver transplantation. METHODS: A conventional pairwise meta-analysis between patients with and without pre-transplant PVT was conducted using hazard ratios or odds ratios where appropriate. RESULTS: Prevalence of preoperative PVT was 11.6% (CI 9.70-13.7%). Pre-operative PVT was associated with increased overall mortality (HR 1.45, 95% CI 1.27-1.65) and graft loss (HR 1.58, 95% CI 1.34-1.85). In particular, grade 3 (HR 1.59, 95% CI 1.00-2.51) and 4 (HR 2.24, 95% CI 1.45-3.45) PVT significantly increased mortality, but not grade 1 or 2 PVT. Patients with PVT receiving living donor (HR 1.54, 95% CI 1.24-1.91) and deceased donor (HR 1.52, 95% CI 1.21-1.92) liver transplantation had increased mortality, with no significant difference between transplant types (P = .13). Furthermore, pre-transplant PVT was associated with higher occurrence of post-transplant PVT (OR 5.06, 95% CI 3.89-6.57). Waitlist mortality was not significantly increased in patients with pre-transplant PVT. CONCLUSION: Graft failure, mortality, and post-operative PVT are more common in pre-transplant PVT patients, especially in grade 3 or 4 PVT. Prophylactic anticoagulation can be considered to reduce re-thrombosis and improve survival.

INTRODUCTION: Prevalence of chronic hepatitis C (CHC) is higher in patients born between 1955-1975. The aim was to perform an economic evaluation of an age-based electronic health record (EHR) alert in primary care to detect patients with undiagnosed CHC and its treatment in comparison with non-use of the alert system, in Valencian Community, Spain. MATERIALS AND METHODS: Decision trees and Markov model were used to evaluate the diagnosis and progression of the disease, respectively. CHC was diagnosed by serology and viral load in seropositive subjects. Epidemiological data and diagnostic costs were extracted from public sources of the Valencian Community. Probabilities, utilities and costs of model states were obtained from the literature. The impact on mortality and hepatic complications avoided by the implementation of the alert were estimated, and efficiency was measured as an incremental cost-utility ratio (ICUR) based on quality-adjusted life years (QALYs) and the costs of both alternatives. RESULTS: The EHR alert detected 269,548 patients, of whom 1,331 had CHC (vs. 23 patients with non-alert). Over the patients' lifetime, the alert would prevent 93% of decompensated cirrhosis cases, 87% of hepatocellular carcinomas, 90% of liver transplants, and 89% of liver related deaths compared to non-use of the alert system. In addition, it would obtain an additional 3.3 QALY per patient, with an incremental cost of €10,880 and an ICUR of €3,321. CONCLUSIONS: The implementation of an age-based EHR alert in primary care to detect patients with CHC reduces hepatic complications and mortality and is an efficient strategy.

The relationship between dietary factors and liver disease remains poorly understood. This study evaluated the associations of whole grain and dietary fiber intake with liver cancer risk and chronic liver disease mortality. The National Institutes of Health-American Association of Retired Persons Diet and Health Study cohort recruited 485, 717 retired U.S. participants in 1995-1996. Follow-up through 2011 identified 940 incident liver cancer cases and 993 deaths from chronic liver disease. Compared with the lowest, the highest quintile of whole grain intake was associated with lower liver cancer risk (Hazard ratio [HR]Q5 vs. Q1 = 0.78, 95% confidence interval [CI]: 0.63-0.96) and chronic liver disease mortality (HRQ5 vs. Q1 = 0.44, 95% CI: 0.35-0.55) in multivariable Cox models. Dietary fiber was also associated with lower liver cancer risk (HRQ5 vs. Q1 = 0.69, 95% CI: 0.53-0.90) and chronic liver disease mortality (HRQ5 vs. Q1 = 0.37, 95% CI: 0.29-0.48). Fiber from vegetables, beans and grains showed potential protective effect. Here, we show that higher intake of whole grain and dietary fiber are associated with lower risk of liver cancer and liver disease mortality.

INTRODUCTION AND OBJECTIVES: In many studies, varying degrees of liver damage have been reported in more than half of the COVID-19 patients. The aim of this study is to determine the effect of liver biochemical parameters abnormality on mortality in critical COVID-19 patients who have been followed in the ICU since the beginning of the pandemic process. MATERIALS AND METHODS: In this study 533 critical patients who admitted to the ICU due to COVID-19 were included. The patients were divided into three groups according to their ALT, AST, and total bilirubin levels at their admission to the ICU. Group 1 was formed of patients with normal liver biochemical parameters values; Group 2 was formed of patients with liver biochemical parameters abnormality; Group 3 was formed of patients with liver injury. RESULTS: 353 (66.2%) of all patients died. Neutrophil, aPTT, CRP, LDH, CK, ALT, AST, bilirubin, procalcitonin and ferritin values in Group 2 and Group 3 were found to be statistically significantly higher than Group 1. It was detected that the days of stay in ICU of the patients in Group 1 was statistically significantly longer than others group. It was found that the patients in Groups 2 and 3 had higher total, 7-day, and 28-day mortality rates than expected. CONCLUSIONS: The study showed that liver disfunction was associated with higher mortality and shorter ICU occupation time.
