The main objective of our study was to assess patient safety culture in Romanian anesthesia and intensive care departments (AICDs), to pinpoint the areas that may need improvement, and to examine the correlation between the prevalence of adverse event reporting, as well as the level of self-reported patient safety culture.

The Yin and Yang dualistic features of autophagy in thermal burn wound healing.

Burn healing should be regarded as a dynamic process consisting of two main, interrelated phases: (a) the inflammatory phase when neutrophils and monocytes infiltrate the injury site, through localized vasodilation and fluid extravasation, and (b) the proliferative-remodeling phase, which represents a key event in wound healing. In the skin, both canonical autophagy (induced by starvation, oxidative stress, and environmental aggressions) and non-canonical or selective autophagy have evolved to play a discrete, but, essential, "housekeeping" role, for homeostasis, immune tolerance, and survival. Experimental data supporting the pro-survival roles of autophagy, highlighting its Yang, luminous and positive feature of this complex but insufficient explored molecular pathway, have been reported.

Targeting PI3K/AKT/mTOR Signaling Pathway in Pancreatic Cancer: From Molecular to Clinical Aspects.
