Comment Review
The interaction of bile acids and gut inflammation influences the pathogenesis of inflammatory bowel disease.
Bile acids (BA) are amphipathic molecules originating from cholesterol in the liver and from microbiota-driven biotransformation in the colon. In the gut, BA play a key role in fat digestion and absorption and act as potent signaling molecules on the nuclear farnesoid X receptor (FXR) and membrane-associated G protein-coupled BA receptor-1 (GPBAR-1). BA are, therefore, involved in the maintenance of gut barrier integrity, gene expression, metabolic homeostasis, and microbiota profile and function. ⋯ These factors contribute to impaired repair capacity of the mucosal barrier, due to chronic inflammation. A better understanding of BA-dependent mechanisms paves the way to innovative therapeutic tools by administering hydrophilic BA and FXR agonists and manipulating gut microbiota with probiotics and prebiotics. We discuss the translational value of pathophysiological and therapeutic evidence linking BA homeostasis to gut inflammation in IBD.

Observational Study
Albumin as a prognostic marker of 30-day mortality in septic patients admitted to the emergency department.
Assessing the evolutive risk of septic patients in the emergency department (ED) is very complex. Predictive tools are available, but at an early stage, none of them can detect the tissue microvascular alterations underlying the septic process. Hypoalbuminemia is present in critically ill patients in the ICU, and some early indications also suggest its early role in septic patients. ⋯ Serum albumin concentration measured during initial ED assessment can be a useful prognostic marker of 30-day mortality in septic patients.
