The study describes a framework for the development and validation of an Artificial Intelligence (AI) model, leveraging SHG/TPE microscopy along with insights from an expert hepatopathologist, to precisely annotate fibrous septa and nodules in liver biopsies in MASH cirrhosis. A total of 25 liver biopsies from the Belapectin trial (NCT04365868) were randomly selected for training, and an additional 10 for validation. Each biopsy underwent three sections: Smooth Muscle Actin (SMA) and Sirius Red (SR) staining for septa and nodule annotation by pathologists and an unstained section for SHG/TPE imaging and AI annotation using qSepta and qNodule algorithms. Re-training of qSepta and qNodule algorithms was executed based on pathologist annotations. Sensitivity and positive predictive value (PPV) were employed to evaluate concordance with pathologist annotations, both pre- and post-training and during validation. Post-re-training by pathologist annotations, the AI demonstrated improved sensitivity for qSepta annotations, achieving 91% post-training (versus 84% pre-training). Sensitivity for qSepta in the validation cohort also improved to 91%. Additionally, PPV significantly improved from 69% pre-training to 85% post-training and reached 94% during validation. For qNodule annotations, sensitivity increased from 82% post-training to 90% in the validation cohort, while the PPV was consistent at 95% across both training and validation cohorts.This study outlines a strategic framework for developing and validating an AI model tailored for precise histopathological assessment of MASH cirrhosis, using pathologist training and annotations. The outcomes emphasise the crucial role of disease-specific customisation of AI models, based on expert pathologist training, in improving accuracy and applicability in clinical trials, marking a step forward in understanding and addressing the histopathological evaluation of MASH cirrhosis.</p>","PeriodicalId":93331,"journal":{"name":"Liver cancer international","volume":"5 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/lci2.70007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142860569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each person was followed up until death, outcome event, or 31st January 2023. Study outcome was incidence of acute liver injury (ALI) within first 28 days since COVID-19 diagnosis. Severity of ALI and comparison of ALI risk stratified by the presence of CHB infection and HS were also analysed. Incidence rate ratios (IRRs) were estimated by Poisson regression models.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Of 52 259 COVID-19 patients with CHB infection in the cohort, 15 391 people with HS + CHB + COVID-19 and 15 391 people with CHB + COVID-19 were included after matching.

Age-standardised incidence rates (ASIRs), mortality rates (ASMRs) and disability-adjusted life years (DALYs) were extracted for each year from 1990 to 2019. Data were subdivided into males and females. Mortality-to-incidence ratios (MIRs) were calculated. All Indices were reported per 100 000 population, and trends were described using Joinpoint regression.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>ASIRs increased in 17/19 countries in females and 18/19 countries in males between 1990 and 2019. ASMRs increased in all countries except Italy (for both sexes) and Sweden (for females). MIR decreased in all countries except Denmark in males (+8.0) and females (+1.2). Ireland saw the greatest decline in MIR among females (−15.0%) and the United Kingdom for males (−16.4%).
