Dispatcher nurses' experiences of handling drones equipped with automated external defibrillators in suspected out-of-hospital cardiac arrest - a qualitative study.

Background: Reducing the time to treatment by means of cardiopulmonary resuscitation (CPR) and defibrillation is essential to increasing survival after cardiac arrest. A novel method of dispatching drones for delivery of automated external defibrillators (AEDs) to the site of a suspected out-of-hospital cardiac arrest (OHCA) has been shown to be feasible, with the potential to shorten response times compared with the emergency medical services. However, little is known of dispatchers' experiences of using this novel methodology.

Ferrocene-Based N-Heterocyclic Silylenes: Monomeric Silanechalcogenones, Silanimines, Silirenes, and Insertion Products with P.

The stable ferrocene-based N-heterocyclic silylenes fc[(N{B})Si] (A; fc=1,1'-ferrocenylene, {B}=(HCNDipp)B, Dipp=2,6-diisopropylphenyl) and fc[(NDipp)Si] (B) are compared in a study focussing on their reactivity towards a range of small to moderately sized molecular substrates, viz. P, S, Se, MesN (Mes=mesityl), RC≡CH, and RC≡CR (R=Ph, SiMe). The Dipp-substituted congener B exhibits a more pronounced ambiphilicity and is sterically less congested than its 1,3,2-diazaborolyl-substituted relative A, in line with the higher reactivity of the former.

Acute safeguarding essentials in modern-day paediatrics-sexual relationships, consent and confidentiality.

As the third case in the acute safeguarding essentials in modern-day paediatrics series, this article focuses on sexual relationships, consent and confidentiality. Using the scenario of a 15-year-old girl presenting to the emergency department with a positive pregnancy test, it begins with a guide to taking a psychosocial history in young people followed by discussion about some of the legality surrounding sexual relationships in adolescents, issues around consent and considerations for confidentiality in this age group.
