Relevance of liver fibrosis amongst diabetic patients with metabolic-dysfunction associated steatotic liver disease(MAsLD)and knowledge gaps Insulin resistance is paramount in the crosstalk between intrahepatic and extrahepatic pathophysiological mechanisms leading to MAsLD(1),hence gaining special relevance in patients diagnosed with type 2 diabetes(T2D).MAsLD is the term that was recently endorsed by an international multidisciplinary consensus panel to replace non-alcoholic fatty liver disease[as non-alcoholic steatohepatitis(NAsH)was replaced by metabolic dysfunction-associated steatohepatitis(MAsH)](2).

We used a distance-sampling survey method and multivariate statistics to obtain a unique estimate of bird species density and seasonal variation in shade-coffee plantations. Our aim was to determine which cultivation practices among plantations contribute most to bird abundance. We conducted avian species counts at 200 points distributed across 10 shade-coffee plantations bordering the lower slopes of the Mombacho Volcano Natural Reserve, in western Nicaragua. We measured vegetation structure (coffee plants and overstory). We used principal components analysis (PCA) among 14 habitat variables to derive a single phyto-geoclimate summary measure (PGsM). We also used PCA to derive an avian abundance summary measure (AAsM) from three bird survey variables, which proved to be a good predictor of bird density. We found higher bird species densities (AAsM) in organic and traditional polyculture shade coffee plantations whose structurally complex and diverse overstory could be verified by PGsM. However, this finding was true only for birds that were habitat specialists. Our results provide further evidence for promoting organic coffee cultivation practices that maintain a structurally diverse overstory and help retain avian species richness and abundance in coffee plantations.
