Environmental DNA Reveals Habitat Variables Driving Platypus () Distribution Across an Urbanised Landscape.

Freshwater waterways, and species that depend on them, are threatened by urbanisation and the consequences of the urban stream syndrome. In south-east Queensland, Australia, little is known about the impacts of the urban stream syndrome on the platypus (), meaning that populations cannot be adequately managed by conservation practitioners. The aim of this study was to determine how habitat and environmental variables, related to the urban stream syndrome, influenced platypus distribution across this region.

Prothrombin Complex Concentrate vs Factor VII for Refractory Bleeding in Cardiac Surgery.

Background: Perioperative bleeding remains an important complication of cardiac surgery. Current guidelines support goal-directed use of coagulation factor concentrates in refractory bleeding, but the optimal strategy is unclear. Four-factor prothrombin complex concentrate (4F-PCC) has theoretical advantages over recombinant activated factor VII (rFVIIa) because of expanded mechanistic targets and lower rates of adverse events, but comparative data are limited.

Preparing Surrogates for Decision-Making: Development and Pilot Testing of PREPARE For THEIR Care.

Context: Surrogate decision-makers have expressed the need for better preparation around communication and medical decision-making.

Objectives: This mixed-methods feasibility study aimed to assess the feasibility and usability of an online program to prepare surrogates for their role.

Methods: We developed a 2-part program for surrogates called PREPARE For THEIR Care with a diverse group of Community Advisory Board members and caregivers recruited from the National Patient Advocacy Foundation.

The Prominent Subarachnoid Space in Children: How has a Normal Variant Become Medicolegally Life-Threatening Pathology?

A prominent subarachnoid space (SAS) in infants under 24 months is a very common finding and is a normal variant that can be associated with macrocephaly. This must be differentiated from various pathological conditions that also cause a prominent SAS, including a reduction in brain volume, obstruction to the cerebrospinal fluid (CSF) or malformations of the skull. The inappropriate labelling of normal SAS prominence as enlargement due to pathology and misrepresentation of published literature by some author groups has created confusion medicolegally, contributing to inappropriate conclusions that a normal prominent SAS may cause subdural haemorrhage (SDH) and brain injury.

Tired of being tired: Black college students' experiences of racial battle fatigue from highly publicized anti-Black violence.

The highly publicized murders of Breonna Taylor, George Floyd, and Ahmaud Arbery in 2020 sparked public outrage and widespread discussion around anti-Black violence. While some studies have examined the effects of anti-Black violence exposure on mental health outcomes, there is a paucity of research that explores how these racially charged events contribute to cumulative stress and "weathering" for Black people, particularly. Informed by racial battle fatigue theory, this in-depth qualitative study explored the lived experiences of 30 Black male and female undergraduate college students (aged 18-28) exposed to highly publicized acts of anti-Black violence.
