Patients' reasons for leaving an emergency department without being seen: results from a survey-based cohort study during the COVID-19 pandemic.

ObjectivePatients who do not wait (DNW) to be seen are a problem for emergency department (ED) care. The aim of this study was to identify the rate and reasons of DNW patients during 1month of the COVID-19 pandemic.MethodsAn observational cohort study of DNW patients presenting to Austin Hospital ED was carried out in August 2021.

Kisspeptin fiber and receptor distribution analysis suggests its potential role in central sensorial processing and behavioral state control.

Background: Kisspeptin (KP) signaling in the brain is defined by the anatomical distribution of KP-producing neurons, their fibers, receptors, and connectivity. Technological advances have prompted a re-evaluation of these chemoanatomical aspects, originally studied in the early years after the discovery of KP and its receptor We have previously characterized(1) seven KP neuronal populations in the mouse brain at the mRNA level, including two novel populations, and examined their short-term response to gonadectomy.

Methods: In this study, we mapped KP fiber distribution in rats and mice using immunohistochemistry under intact and short- and long-term post-gonadectomy conditions.

Incidence of cervical spine injury in victims of dismounted blast: a systematic review.

Introduction: Dismounted blast has the potential to cause life-threatening injuries to multiple simultaneous casualties, including injury to the cervical spine (c-spine). Spinal immobilisation can be costly in terms of time and personnel required to apply and sustain it. C-spine 'clearing' tools frequently do not apply to the blast-injured casualty, so clinical judgement must be used to determine those requiring c-spine immobilisation.
