Background: Childhood obesity has seen an important rise in recent decades, both the pediatric and adult populations. Excess weight can cause various health complications, such as metabolic syndrome (MetS), a cluster of medical conditions linked to adverse cardiometabolic outcomes. Although MetS may be attributed mainly adults, early life factors, birth characteristics feeding practices, influence its development obese children. Aim: This study aims investigate relationships between metrics,...

Background: Changing the term/concept of non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction associated (MAFLD) may broaden pathological definition that can include chronic renal involvement, and, possibly, changes kidney disease's (CKD's) epidemiological association with disease, because CKD is disorders and almost all patients present some form an atherogenic dyslipidemia. Our study explores relationship between MAFLD using Transient Elastography (TE) a Controlled Attenuated...
