Efficacy of albumin use in decompensated cirrhosis and real-world adoption in Australia.

The current treatment approach to patients with liver cirrhosis relies on the individual management of complications. Consequently, there is an unmet need for an overall therapeutic strategy for primary and secondary prevention of complications. The clinical potential of long-term albumin infusions supported by recent clinical trials has expanded its indications and holds promise to transform the management and secondary prevention of cirrhosis-related complications.

Biomarkers to predict and diagnose pulmonary complications in children post haematopoietic stem cell transplant.

Objectives: Haematopoietic cell transplant (HCT) is a cellular therapy for a group of high-risk children with cancer, immunodeficiency and metabolic disorders. Whilst curative for a child's underlying condition, HCT has significant risks associated, including lung injury. These complications are associated with increased post HCT mortality and require improved methods of risk stratification, diagnosis and treatment.

Objectives: Haematopoietic stem cell transplant (HCT) is a cellular therapy that, whilst curative for a child's underlying disease, carries significant risk of mortality, including because of pulmonary complications. The aims of this study were to describe the burden of pulmonary complications post-HCT in a cohort of Australian children and identify risk factors for the development of these complications.

Methods: Patients were identified from the HCT databases at two paediatric transplant centres in Australia.

Integrated MXene and metal oxide electrocatalysts for the oxygen evolution reaction: synthesis, mechanisms, and advances.

Electrochemical water splitting is a promising approach to produce H through renewable electricity, but its energy efficiency is severely constrained by the kinetically slow anodic oxygen evolution reaction (OER), which uses about 90% of the electricity in the water-splitting process due to its multistep proton (H)-coupled electron (e) transfer process, high overpotential (), and low energy efficiency. Therefore, the quest for efficient, sustainable, and cost-effective electrocatalysts for hydrogen production through water electrolysis has intensified, highlighting the potential of two-dimensional (2D) MXenes. MXenes have emerged as a promising class of materials characterized by excellent stability, hydrophilicity, and conductivity.

Structural and kinetic insights into the stereospecific oxidation of -2,3-dihydroxypropanesulfonate by DHPS-3-dehydrogenase from .

2,3-Dihydroxypropanesulfonate (DHPS) and sulfolactate (SL) are environmentally important organosulfur compounds that play key roles as metabolic currencies in the sulfur cycle. Despite their prevalence, the pathways governing DHPS and SL production remain poorly understood. Here, we study DHPS-3-dehydrogenase from (HpsN), a bacterium capable of utilizing DHPS as a sole carbon source.

Validating older adult patient's Medical Treatment Decision Maker's (MTDM). A retrospective observational study with follow-up phone interview transcript.

A Medical Treatment Decision Maker (MTDM), also referred to as surrogate decision maker, by law, is to be appointed to make medical treatment decisions on behalf of a person who cannot make such decisions for themselves. In the Emergency Department (ED) and acute healthcare services, the clinicians' (nurses and doctors) ability to contact MTDMs is essential for patient care, particularly in time-critical situations. Our primary objective was to review the verification process and assess the accuracy of MTDM contact numbers in the Health Information System (HIS) to assess compliance with legislation.

Incidence and Predictors of Stroke in Australian Adults With Congenital Heart Disease (2000-2017).

Background: Adults with congenital heart disease (CHD) are at increased risk of stroke but high-quality population level data on stroke incidence in these patients are scant.

Methods And Results: A retrospective whole-population Western Australian cohort of adult patients with CHD aged 18 to 64 years was created and followed from January 2000 to December 2017 using linked hospital data. Stroke incidence rates within the adult cohort with CHD were calculated and compared with the general population via direct standardization.

Selective sodium halide over potassium halide binding and extraction by a heteroditopic halogen bonding [2]catenane.

The synthesis and ion-pair binding properties of a heteroditopic [2]catenane receptor exhibiting highly potent and selective recognition of sodium halide salts are described. The receptor design consists of a bidentate halogen bonding donor motif for anion binding, as well as a di(ethylene glycol)-derived cation binding pocket which dramatically enhances metal cation affinity over previously reported homo[2]catenane analogues. H NMR cation, anion and ion-pair binding studies reveal significant positive cooperativity between the cation and anion binding events in which cation pre-complexation to the catenane subsequently 'switches-on' anion binding.

Triplet dynamics reveal loss pathways in multi-resonance thermally activated delayed fluorescence emitters.

Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials are of interest for light-emitting applications due to their narrow emission bandwidths and high photoluminescence quantum yields. Whilst there have been numerous examples of multi-resonance molecules exhibiting efficient TADF, the photophysics and mechanism of TADF in multi-resonance emitters have not been investigated to the same extent as the more conventional spatially separated donor-acceptor TADF materials, limiting the development of MR-TADF devices. Here we study the photophysics of a multi-resonance TADF material, OQAO(mes), using transient absorption spectroscopy to spectrally resolve the triplet population(s).

Describing endosymbiont-host interactions within the parasitism-mutualism continuum.

Endosymbionts are widespread in arthropods, living in host cells with effects that extend from parasitic to mutualistic. Newly acquired endosymbionts tend to be parasitic, but vertical transmission favors coevolution toward mutualism, with hosts sometimes developing dependency. Endosymbionts negatively affecting host fitness may still spread by impacting host reproductive traits, referred to as reproductive "manipulation," although costs for hosts are often assumed rather than demonstrated.

A perspective-driven and technical evaluation of machine learning in bioreactor scale-up: A case-study for potential model developments.

Evolution in coeliac disease diagnosis and management.

The traditional gut-centric view of coeliac disease is evolving as immune and genetic insights underscore the central importance of a systemic, T cell immune response to gluten in disease pathogenesis. As the field increasingly recognize the limitations of small intestinal histology as the diagnostic standard, data supporting the accuracy of an immune (serologic) diagnosis of coeliac disease - well demonstrated in children - are growing for adults. Novel biomarkers such as interleukin-2 that identify the gluten-specific T cell demonstrate high sensitivity and specificity for coeliac disease and offer the potential for a diagnostic approach that avoids the need for gluten challenge.

Critical review of single-cell mechanotyping approaches for biomedical applications.

Accurate mechanical measurements of cells has the potential to improve diagnostics, therapeutics and advance understanding of disease mechanisms, where high-resolution mechanical information can be measured by deforming individual cells. Here we evaluate recently developed techniques for measuring cell-scale stiffness properties; while many such techniques have been developed, much of the work examining single-cell stiffness is impacted by difficulties in standardization and comparability, giving rise to large variations in reported mechanical moduli. We highlight the role of underlying mechanical theories driving this variability, and note opportunities to develop novel mechanotyping devices and theoretical models that facilitate convenient and accurate mechanical characterisation.
