Consistently, hepatic expression of genes crucial for de novo lipogenesis was markedly suppressed only in male, but not female, Hdac9 KO mice. However, Hdac9 deletion had a minimal effect on hepatic inflammation and fibrosis. In WAT, Hdac9 KO showed less adipocyte hypertrophy, inflammation, and fibrosis in male mice compared with WT. In addition, indirect calorimetry demonstrated that male Hdac9 KO mice had significantly higher metabolic rates, respiratory exchange ratios, and energy expenditure without altering physical activities than WT, which was not observed in female mice.Conclusions: Our findings indicate that global deletion of Hdac9 prevented the development of obesity, hepatic steatosis, and WAT inflammation and fibrosis in male mice with diet-induced obesity and MASH, suggesting that a sex-dependent role of HDAC9 may exist in the pathways mentioned above.","PeriodicalId":15877,"journal":{"name":"Journal of Gastroenterology and Hepatology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142895178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, TL signatures (TLSs) were constructed based on different source domains, including whole slide images (TLS-WSIs) and natural images (TLS-ImageNet). Clinical model and non-TLS based on CT images were constructed simultaneously. Second, TL radiomic model (TLRM) was constructed by combining optimal TLS and clinical factors. Finally, the performance of the models was evaluated by ROC analysis. The clinical utility of the models was assessed using integrated discriminant improvement (IDI) and decision curve analysis (DCA).Results: TLS-WSI significantly outperformed TLS-ImageNet, non-TLS, and clinical models (p < 0.05). The AUC value of TLS-WSI in training cohort was 0.9459 (95CI%: 0.9054, 0.9863) and ranged from 0.8050 (95CI%: 0.7130, 0.8969) to 0.8984 (95CI%: 0.8420, 0.9547) in validation cohorts.

This study aims to validate and compare previous prediction models for HCC outcomes in 488 LDLT recipients.Methods: For 488 patients who underwent LDLT for HCC, pretransplant imaging studies assessed by modified RECSIT criteria, tumor markers such as alpha feto-protein (AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA II), and explant pathology were recruited. C-index of models for the HCC outcomes was compared, followed by further investigation for the predictive performances of the best model.Results: We found MoRAL (11√PIVKA-II + 2√AFP) demonstrated a higher C-index for HCC recurrence than other models that included radiologically viable tumor number and/or size (MoRAL: 0.709, Milan: 0.537, UCSF: 0.575, Up-to-7: 0.572, French AFP: 0.634, Pre-MORAL: 0.637, HALT-HCC: 0.626, Metroticket2.0: 0.629) and also had the highest C-index for HCC-specific deaths (0.706).

However, studies on the prognostic factors in very elderly patients are limited. Therefore, we aimed to explore the prognostic factors affecting overall survival (OS) in patients aged ≥ 80 with superficial ESCC who underwent ESD.Methods: This study included 155 patients aged ≥ 80 who underwent ESD for superficial ESCC. Clinicopathological findings and long-term outcomes were examined. The prognostic nutritional index (PNI) and geriatric nutritional index (GNRI) were used to assess pre-treatment nutritional status.Results: Twenty-nine patients (18.7%) were aged ≥ 85. Thirty-five (22.6%) and 61 (39.4%) patients had a GNRI < 92 and PNI < 45, respectively. Metastatic relapse was observed in five cases, four (80%) of which resulted in death due to the primary disease. The median OS of all patients was 86 months. Although factors specifically associated with disease-specific survival were not identified, GNRI, PNI, comorbidity, and physical status were associated with OS. In multivariate analysis, age ≥ 85 years (p = 0.03), GNRI (p < 0.01), and PNI (p < 0.01) remained factors associated with OS. Patients aged ≥ 85 with either GNRI ≥ 92 or PNI ≥ 45 had a median OS of 106 months, whereas those aged ≥ 85 with GNRI < 92 had a median OS of 12 months.Conclusions: GNRI and PNI are important indicators for assessing the suitability of ESD in elderly patients aged ≥ 80. These indices can help predict OS and guide clinical decision-making for this patient population.","PeriodicalId":15877,"journal":{"name":"Journal of Gastroenterology and Hepatology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142895194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food insecurity, a crucial social determinant of health, remains unclearly associated with CC and CD. We aim to explore the association between food insecurity and CC and CD, and its impact on all-cause mortality among participants with abnormal bowel health.Methods: We used data from National Health and Nutrition Survey 2005-2010. We assessed food insecurity using the Household Food Security Survey Module, and bowel health, including CD and CC, was evaluated using fecal characteristics and bowel movement frequency from the Bowel Health Questionnaire. Finally, 13 199 participants were included.Results: A total of 15.26% (2014) participants experienced food insecurity. Multivariate analysis revealed that food insecurity was associated with a higher proportion of CD (odds ratio [OR]: 1.24, 95% confidence interval [CI]: 1.02-1.52, p = 0.03), especially in women. CC did not exhibit a significant association with food insecurity (OR: 1.10, CI: 0.86-1.40, p = 0.41).

Patients with 49 uncommon-type gastric cancer types were excluded. The risk of metastasis for pT1a cancers with lymphatic involvement was quantified by comparing lymph node metastasis and/or metastatic recurrence in patient groups who underwent additional surgery post-ESD or did not undergo surgery but were followed up for > 3 years.Results: Among the 6748 pT1a cancers treated by ESD, 41 lesions (0.6%) had histologically confirmed lymphatic involvement.
