Patients at each shock stage may behave and present differently with a spectrum of shock severity and adverse outcomes. Shock severity, shock aetiology, and several factors should be integrated in management decision-making. Although the contemporary shock stages classification provided a standardized shock severity assessment, individual agents or management strategy has not yet been studied in the context of each shock stage.

Background: The coronavirus pandemic has had a profound impact on organization and delivery of care. The challenges faced by healthcare organizations in dealing with the pandemic have intensified interest in the concept of resilience. While effort has gone into conceptualising resilience, there has been relatively little work on how to evaluate organizational resilience.

This paper presents the first ever direct measurements of total pressure losses across shocks in supersonic flows of organic vapors in non-ideal conditions, so in the thermodynamic region close to the liquid-vapor saturation curve and the critical point where the ideal gas law is not applicable. Experiments were carried out with fluid siloxane MM (hexamethyldisiloxane, C H OSi ), commonly employed in medium-/high-temperature organic Rankine cycles (ORCs), in the (TROVA), a blowdown wind tunnel at the Laboratory of Compressible fluid dynamics for Renewable Energy Applications (CREA lab) of Politecnico di Milano. A total pressure probe was inserted in superheated MM vapor flow at Mach number with total conditions in the range and at varying levels of non-ideality, with a compressibility factor evaluated at total conditions between .

Rationale And Objectives: Post-traumatic stress disorder (PTSD) is characterized by poor adaptation to a traumatic experience and disturbances in fear memory regulation, and currently lacks effective medication. Cannabidiol is a main constituent of Cannabis sativa; it has no psychotomimetic effects and has been implicated in modulating fear learning in mammals. Using a mouse PTSD model, we investigated the effects of CBD on PTSD-like behaviors and the modulation of trauma-related fear memory, a crucial process leading to core symptoms of PTSD.

An isolated superior mesenteric artery (SMA) dissection (ISMAD) is extremely rare among visceral artery dissections. Its diagnosis is made by abdominal contrast CT scan which shows SMA occlusion partially or completely. The ISMAD is classified into 6 types: type I-V has partial occlusion and treated medically using antiplatelets or anticoagulants.
