Few studies have been conducted on the relationship between “outside-residing” resilience characteristics and the risk of developing drug use disorder later in life. These characteristics include responsive and caring parenting, household routines involving regular family meals and bedtime routines, social support from peers, participation in organized activities, and religious service attendance.

Many drugs are effective systemically, but slow onset of non-intravenous routes of administration may limit their clinical utility. While anesthesiologists usually have intravenous (IV) access for drug delivery, other healthcare professionals in less controlled situations such as acute crises in the emergency room, critical care settings, or urgent needs in the community, may need non-invasive drug delivery [1].

The purpose of this document is to provide a unique white paper on the use of different anesthetic drugs and the key clinical pearls for ensuring patient safety in humans. This paper is designed to be a convenient guide that can be placed in work rooms for residents and medical school trainees to improve their learning and to provide reminders about drug-drug interactions.

Overcrowding is a growing problem that prevails in the urban areas of both developing and developed countries. It is considered as psycho-social stress that affects the behavior and physiology of individuals and societies [1]. 
Scientific awareness of overcrowding stress systematically started in the 1960s with the early experiments of John B. Calhoun using the so-called “rat utopia” and the theory of “behavioral sink” [2]. Depending on Calhoun’s experiments, connections between the model of rodent colonies and the arising problems of crowded cities were extrapolated [3].

In recent years, stress and stress-coping mechanisms constitute a growing public healthcare issue concerning modern society. Experiencing stress engenders a great complex mechanism named stress response, which consists of a rapid release of catecholamines by the sympathetic nervous system, followed by a slower response in which hormones, mainly glucocorticoids (GCs), are synthesized and released to the bloodstream.
