Coronary artery calcification as an incremental predictive risk: Research perspectives in primary prevention.

Coronary artery calcium (CAC) score is a neglected biomarker that can be derived from non-cardiac chest computed tomography scan and represents a surrogate for atherosclerosis. We created a simulation model using different CAC score values in the MESA coronary artery risk score in a population derived from the Fourier Trial. CAC score could modulate the sample sizes of cardiovascular trials in primary and secondary prevention and offer new primary prevention treatments to high-risk subjects with reasonable numbers needed to treat comparable to secondary prevention trials.

Lactobacilli Cell-Free Supernatants Modulate Inflammation and Oxidative Stress in Human Microglia via NRF2-SOD1 Signaling.

Microglia are macrophage cells residing in the brain, where they exert a key role in neuronal protection. Through the gut-brain axis, metabolites produced by gut commensal microbes can influence brain functions, including microglial activity. The nuclear factor erythroid 2-related factor 2 (NRF2) is a key regulator of the oxidative stress response in microglia, controlling the expression of cytoprotective genes.

Psychobiotic Properties of in Neurodegenerative Diseases.

Neurodegenerative disorders are the main cause of cognitive and physical disabilities, affect millions of people worldwide, and their incidence is on the rise. Emerging evidence pinpoints a disturbance of the communication of the gut-brain axis, and in particular to gut microbial dysbiosis, as one of the contributors to the pathogenesis of these diseases. In fact, dysbiosis has been associated with neuro-inflammatory processes, hyperactivation of the neuronal immune system, impaired cognitive functions, aging, depression, sleeping disorders, and anxiety.
