Associations between Intensive care unit acquired weakness with post-extubation dysphagia and other clinical outcomes-a cohort study in critically ill respiratory patients.

Background: Intensive care unit-acquired weakness (ICU-AW) is a complication characterized by decreased muscle mass and impairments in strength and physical function and is associated with poor quality of life and worse clinical outcomes. The primary objective of this study is to analyze the prevalence of ICU-AW, and secondary objectives were to assess risk factors and analyze the associations with clinical outcomes.

Methods: This is a prospective cohort study of patients on mechanical ventilation (MV).

Looking Inside of the Intestinal Permeability Regulation by Protein-Derivatives from Bovine Milk.

The prime function of the epithelium is to regulate the intestinal permeability; the latter is a quantitative parameter that refers to the measurement of the rate of passage of solutes through the epithelial monolayer. Function of epithelial monolayer depends on the expression of protein complexes known as tight junction proteins; whose function and expression can be disrupted under conditions of inflammation including irritable bowel disease (IBD), intestinal infections, and high-fat diets, among others. This manuscript is focused to outline the effects of bovine milk protein derivatives on the intestinal permeability addressed mostly in animal models in which the intestinal barrier is disrupted.

Lipocalin-2 as a fundamental protein in type 2 diabetes and periodontitis in mice.

Background: Lipocalin-2 (LCN-2) is an osteokine that suppresses appetite, stimulates insulin secretion, regulates bone remodeling, and is induced by proinflammatory cytokines. The aim of this work was to investigate the participation of LCN-2 in periodontitis associated with type 2 diabetes (T2D) by evaluating alveolar bone loss, glycemic control, inflammation, and femur fragility.

Methods: A murine model of periodontitis with T2D and elevated LCN-2 concentration was used.

Moderate Aerobic Exercise Induces Homeostatic IgA Generation in Senile Mice.

A T-cell-independent (TI) pathway activated by microbiota results in the generation of low-affinity homeostatic IgA with a critical role in intestinal homeostasis. Moderate aerobic exercise (MAE) provides a beneficial impact on intestinal immunity, but the action of MAE on TI-IgA generation under senescence conditions is unknown. This study aimed to determine the effects of long-term MAE on TI-IgA production in young (3 month old) BALB/c mice exercised until adulthood (6 months) or aging (24 months).
