Preparedness of Australasian emergency departments for point-of-care ultrasound in the COVID-19 pandemic.

Introduction: Point-of-care ultrasound (POCUS) has been brought to the limelight again, with a surge in lung ultrasound in suspected COVID-19 patients. This is due to POCUS superiority over chest X-ray, equivalent efficacy to computerised tomography chest for COVID-19 diagnosis and potential minimisation of cross-infection. However, inadequate disinfection practices could make ultrasound machines a vector for disease transmission.

Land snail biogeography and endemism in south-eastern Africa: Implications for the Maputaland-Pondoland-Albany biodiversity hotspot.

Invertebrates in general have long been underrepresented in studies on biodiversity, biogeography and conservation. Boundaries of biodiversity hotspots are often delimited intuitively based on floristic endemism and have seldom been empirically tested using actual species distributions, and especially invertebrates. Here we analyse the zoogeography of terrestrial malacofauna from south-eastern Africa (SEA), proposing the first mollusc-based numerical regionalisation for the area.

A biting commentary: Integrating tooth characters with molecular data doubles known species diversity in a lineage of sea slugs that consume "killer algae".

Predicting biotic resistance to highly invasive strains of "killer algae" (Caulerpa spp.) requires understanding the diversity and feeding preferences of native consumers, including sea slugs in family Oxynoidae. Past studies reported low algal host specificity for Oxynoe (6 spp.

Revision of the dwarf cannibal snails (Nata s.l.) of southern Africa-Nata s.s. and Natella (Mollusca: Gastropoda: Rhytididae), with description of three new species.

This paper represents the second part of our revisionary studies on the rhytidid fauna of southern Africa. The species discussed belong to the taxon Nata s.l.

Prestonellinae-validation of the name as a new subfamily of Bothriembryontidae (Mollusca, Gastropoda, Orthalicoidea).

The affinities of the enigmatic South African land snail genus Prestonella Connolly, 1929 were discussed by Herbert (2007) and Herbert & Mitchell (2009), who showed, on the basis of morphological and molecular data, that the genus is referable to the superfamily Orthalicoidea. Currently, the three described species of Prestonella are the only known African representatives of this diverse superfamily. Earlier, van Bruggen (1978) had recognized that these species formed a distinct group and had placed them in the (new) family Prestonellidae.

An annotated catalogue and bibliography of the taxonomy, synonymy and distribution of the Recent Vetigastropoda of South Africa (Mollusca).

A complete inventory of the known Recent vetigastropod fauna of South Africa is provided. Bibliographic citations to works discussing the taxonomy, synonymy and distribution of the species in a southern African or south-western Indian Ocean context are provided. Additional explanatory notes are given where pertinent.

Deep molecular divergence and exceptional morphological stasis in dwarf cannibal snails Nata sensu lato Watson, 1934 (Rhytididae) of southern Africa.

The genus Nata Watson, 1934 is a southern African endemic belonging to the Gondwanan family of carnivorous snails, Rhytididae. We present a molecular phylogeny of the genus based on two mitochondrial (16S and COI) and two nuclear genes (ITS2 and 28S RNA), and complement this with an appraisal of morphological characters relating to both the shell and soft parts. We identify four reciprocally monophyletic lineages for which valid names are already available, plus two undescribed species restricted to the Albany Thicket Biome.

New genus Arxellia with new species of Solariellidae (Gastropoda: Trochoidea) from New Caledonia, Papua New Guinea, Philippines, Western Australia, Vanuatu and Tonga.

A new genus, Arxellia, is described in the family Solariellidae. Nine species are referred to this taxon, eight of which are new and are described in this paper (Arxellia trochos n. sp.

Prolonged venovenous extracorporeal membrane oxygenation without anticoagulation: a case of Goodpasture syndrome-related pulmonary haemorrhage.

We present a 16-year-old male with severe acute respiratory and renal failure as a result of Goodpasture syndrome, requiring venovenous extracorporeal membrane oxygenation (VV-ECMO) for pulmonary haemorrhage. The patient received no systemic anticoagulation for 25 of 26 ECMO days (20 days consecutively) and suffered no coagulation-related adverse events. The patient had a subtherapeutic anticoagulation profile according to recommended ECMO guidelines during most of this time.

A phylogeny of the cannibal snails of southern Africa, genus Natalina sensu lato (Pulmonata: Rhytididae): assessing concordance between morphology and molecular data.

The genus Natalina Pilsbry, 1893 is a southern African endemic belonging to the Gondwanan family of carnivorous snails, Rhytididae. We present a well-resolved molecular phylogeny of the genus based on the mitochondrial 16S and COI genes and the nuclear ITS2 gene, and assess this in light of Watson's [Watson, H., 1934.
