Article Abstract

Unlabelled: Nonalcoholic fatty liver disease (NAFLD) is a leading cause of hepatocellular carcinoma (HCC) in the United States. Prior data suggest that NAFLD-HCC patients are less likely to receive liver transplantation (LT) and have worse overall survival; however, the reason for this discrepancy is unknown.

Methods: We conducted a retrospective study of 631 HCC patients listed for LT at a large academic center from 2004 to 2013. Waitlist dropout and LT were analyzed using competing risk regression.

Results: Compared with other-HCC patients (n = 589), NAFLD-HCC patients (n = 42, 6.7%) were older (65 versus 58,  < 0.001) with more women (50.0 versus 23.6%,  < 0.001), Hispanic ethnicity (40.5 versus 17.7%,  = 0.001), obesity (69.0 versus 29.9%,  < 0.001), diabetes mellitus (59.5 versus 27.8%,  < 0.01), insulin-dependence (23.8 versus 10.2%,  = 0.007), hyperlipidemia (40.5 versus 10.5,  < 0.001), and statin use (33.3 versus 5.3%,  < 0.001). Cumulative incidence of waitlist dropout at 2 y was 17.4% (95% confidence intervals, 7.7-30.4) for NAFLD HCC and 25.4% (95% confidence intervals, 21.9-29.0) for other HCC ( = 0.28). No difference in waitlist dropout or receipt of LT between NAFLD HCC and other HCC was found on regression analysis. Similarly, NAFLD and obesity, obesity alone, diabetes mellitus, insulin-dependence, hyperlipidemia, and statin use were not associated with waitlist outcomes. Finally, we observed no statistically significant difference in 5-y survival from HCC diagnosis between NAFLD HCC and other HCC (78.5% versus 66.9%,  = 0.9).

Conclusions: In our single-center cohort, we observed no difference in waitlist outcomes or survival in NAFLD HCC, although conclusions are limited by the small number of NAFLD-HCC patients. Notably, the inclusion of patients with obesity in the NAFLD-HCC group and stratification by individual metabolic factors also showed no difference in waitlist outcomes.

This study explores how human antigen R (HuR) stabilizes fibroblast growth factor 19 (FGF19) mRNA, inhibiting Kupffer cell (KC) activation to reduce inflammation and fibrosis in non-alcoholic fatty liver disease (NAFLD). An animal model of NAFLD was established in mice by administering a high-fat diet (HFD). In vitro study utilized a lipopolysaccharide-induced immortalized mouse KC model.

Increasing evidence indicates a potential link between macrophage colony-stimulating factor 1 (CSF1) and macrophage migration inhibitory factor (MIF) with nonalcoholic fatty liver disease (NAFLD). However, the causal relationships remain unclear. This study aims to clarify the causal associations between CSF1, MIF, and NAFLD using Mendelian randomization (MR) analysis.

This study aimed to analyze the amino acid composition and characterize the sequences of collagen peptides from Skipjack tuna bones (TBCPs) by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and further investigate the function and mechanism of action of TBCPs in nonalcoholic fatty liver disease (NAFLD). The results showed that TBCPs contain 16 types of amino acids, among which glycine is the most abundant, and hydrophobic amino acids account for 40.75 %.

Background: Our study aimed to develop a predictive model for the risk of obstructive sleep apnea (OSA) in bariatric surgery candidates for utilization during the preoperative evaluation.

Methods: Relevant clinical data were retrospectively collected for 453 patients who met the inclusion criteria and did not meet the exclusion criteria; the patients were randomized into training and test cohorts. Univariate analysis was performed on the training set.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global health concern, particularly among individuals with obesity. While metabolic and behavioral risk factors have been well described, the role of psychosocial determinants, such as weight stigma, remains underexplored.

Objectives: To assess the association between sociodemographic variables, healthy lifestyle behaviors, and internalized weight stigma with MASLD risk in a large cohort of obese workers across Spain.
