Circulating miRNAs as Biomarkers of Subclinical Atherosclerosis Associated with Severe Obesity before and after Bariatric Surgery.

Introduction: Severe obesity results in high cardiovascular risk (CVR), increasing morbidity, and mortality. New and improved methods are needed to detect cardiovascular diseases rapidly in severe obesity. microRNAs (miRNAs) has shown promise as diagnostic tools.

The response to fasting and refeeding reveals functional regulation of lipoprotein lipase proteoforms.

Lipoprotein lipase (LPL) is responsible for the intravascular catabolism of triglyceride-rich lipoproteins and plays a central role in whole-body energy balance and lipid homeostasis. As such, LPL is subject to tissue-specific regulation in different physiological conditions, but the mechanisms of this regulation remain incompletely characterized. Previous work revealed that LPL comprises a set of proteoforms with different isoelectric points, but their regulation and functional significance have not been studied thus far.

Irisin as a Novel Biomarker of Subclinical Atherosclerosis in Severe Obesity.

Severe obesity (SO) can accelerate atherosclerosis and the onset of acute cardiovascular events. The diagnosis of atherosclerosis in the context of a high body mass index (BMI) can be challenging, making the identification of biomarkers clinically relevant. We aimed to assess the usefulness of irisin as a biomarker for subclinical atherosclerosis in participants with SO.

Apo AIV and Citrulline Plasma Concentrations in Short Bowel Syndrome Patients: The Influence of Short Bowel Anatomy.

Introduction: Parenteral nutrition (PN) dependence in short bowel syndrome (SBS) patients is linked to the functionality of the remnant small bowel (RSB). Patients may wean off PN following a period of intestinal adaptation that restores this functionality. Currently, plasma citrulline is the standard biomarker for monitoring intestinal functionality and adaptation.
