Gender equity in authorship of emergency medicine publications in Australasia.

Objective: To evaluate gender authorship trends in the official journal of the Australasian College for Emergency Medicine (ACEM), Emergency Medicine Australasia (EMA).

Methods: A bibliometric review of author gender in EMA during the 10-year period 2013-2022. The gender of first/last authors were determined by www.

Lateral subvastus approach to total knee arthroplasty: A novel surgical technique and retrospective review of 931 consecutive cases.

Background: The lateral muscle-sparing approach total knee arthroplasty (TKA) has been detailed and indicated selectively for severe valgus deformities. We present the largest, to date, consecutive series of lateral subvastus TKAs and we hypothesize that preoperative alignments would demonstrate no differences in range of motion (ROM), knee society scores (KSS), kneeling ability, patient satisfaction, or complications.

Materials And Methods: This retrospective study examined 931 primary TKAs in 824 patients performed through the lateral subvastus approach with one to two years follow-up.

What effect did the New Zealand COVID-19 lockdown have on computed tomography-head scan utilisation in patients presenting to the emergency department with traumatic head injuries?

Objectives: To explore the unique impact the first COVID-19 national lockdown in New Zealand (NZ) had on the utility of computed tomography (CT)-head scanning in patients presenting to the ED with head injuries.

Methods: Retrospective observational study of CT-head use in head-injured patients presenting to the ED during the 2020 COVID-19 lockdown compared to the corresponding time period in 2019.

Results: During the lockdown period in 2020, the total number of ED presentations reduced by 30.

Deployment of biologging tags on free swimming large whales using uncrewed aerial systems.

Suction-cup-attached biologging tags have led to major advances in our understanding of large whale behaviour. Getting close enough to a whale at sea to safely attach a tag is a major limiting factor when deploying these systems. Here we present an uncrewed aerial system (UAS)-based tagging technique for free-swimming large whales and provide data on efficacy from field testing on blue () and fin () whales.
