Introduction: Nonalcoholic fatty liver disease (NAFLD) is one of the leading causes of chronic liver disease. The spectrum of NAFLD includes simple steatosis, nonalcoholic steatohepatitis (NASH), advanced fibrosis, and cirrhosis. Our study aimed to calculate visceral fat volume at the L3-L4 vertebral level and its association with hepatic fibrosis assessed by transient elastography.
Methods: All patients above 18 years undergoing computed tomography (CT) abdomen in the Department of Radiodiagnosis of Medical College Thiruvananthapuram during the study period with NAFLD were included. Transient elastography was done. Patients were categorized to advanced fibrosis (>10 kPa) and without advanced fibrosis (<10 kPa). The area under the receiver operating characteristic (AUROC) curve was plotted.
Results: Sixty-four patients comprised 36 males and 28 females. Thirty-one (46%) were having advanced fibrosis (transient elastography>10 kPa) and 34 (54%) patients were without advanced fibrosis. About 0.733 was the AUROC for visceral fat in predicting advanced fibrosis. The cutoff was 167.5cm3 (sensitivity was 77.4% and specificity was 51.5% in predicting advanced fibrosis).
Conclusion: About 0.733 was the AUROC for visceral fat in predicting advanced fibrosis. The cutoff was 167.5cm3 (sensitivity was 77.4% and specificity was 51.5% in predicting advanced fibrosis).

Perivascular cells function as key mediators of mechanical and structural changes in vascular capillaries.

A hallmark of chronic and inflammatory diseases is the formation of a fibrotic and stiff extracellular matrix (ECM), typically associated with abnormal, leaky microvascular capillaries. Mechanisms explaining how the microvasculature responds to ECM alterations remain unknown. Here, we used a microphysiological model of capillaries on a chip mimicking the characteristics of healthy or fibrotic collagen to test the hypothesis that perivascular cells mediate the response of vascular capillaries to mechanical and structural changes in the human ECM.

Background: Clot waveform analysis (CWA) provides a global assessment of hemostasis and may be useful for patients with cirrhosis with complex hemostatic abnormalities. This study aimed to assess the association between prothrombin time (PT-) and activated partial thromboplastin time (aPTT-) based CWA parameters and cirrhosis severity and prospectively evaluate the role of CWA in predicting mortality and acute decompensation (AD) over 1 year.
Methods: This prospective study included adult patients with cirrhosis between June 2021 and December 2023 at Chulalongkorn University Hospital.

Aim: Computed tomography (CT)-derived extracellular volume fraction (ECV) is a non-invasive method to quantify myocardial fibrosis. Evaluating CT-ECV during aortic valve replacement (AVR) planning CT in severe aortic stenosis (AS) may aid prognostic stratification. This meta-analysis evaluated the prognostic significance of CT-ECV in severe AS necessitating AVR.

Introduction: Lumacaftor/ivacaftor (lum/iva) was introduced in the Netherlands in 2017. We investigated 1-year efficacy of lum/iva on lung function and small airway and structural lung disease evaluated by multiple breath nitrogen washout and CT scan. Additionally, we investigated effects of lum/iva on exacerbations, anthropometry, sweat chloride and safety in children with CF in the Netherlands.
