Trends in the surgical management of proximal humerus fractures over the last 20 years from Australian registry databases.

Background: Proximal humerus fractures (PHF) are common with approximately 30% requiring surgical intervention. This ranges from open reduction internal fixation (ORIF) to shoulder arthroplasty (including hemiarthroplasty, total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA)). The aim of this study was to assess trends in operative interventions for PHF in an Australian population.

A comparative analysis of a central metaphyseal humeral fixation stemless shoulder arthroplasty to an anatomic shoulder arthroplasty in a national registry cohort.

Background: This study aimed to determine the revision outcome between a centrally fixed stemless anatomic design and other total anatomic shoulder replacements using data from a large national arthroplasty registry.

Methods: The study period was from December 2011 to December 2022 and included three cohorts; primary Affinis stemless anatomic (AFS), all other primary total stemless anatomic (sTSA) and primary total stemmed anatomic shoulder arthroplasty (aTSA). The endpoint was all-cause revision using cumulative percent revision (CPR).

PFOA, PFOS and PFHxS toxicokinetic considerations for the development of an in vivo approach for assessing PFAS relative bioavailability in soil.

A Sprague-Dawley rat model was utilized to elucidate perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS) and perfluorohexanesulfonic acid (PFHxS) toxicokinetics with a goal of developing an in vivo approach for quantifying PFAS relative bioavailability in impacted soil. Following single dose administration (gavage) of ∼ 0.2-2000 µg kg BW of PFOA, PFOS or PFHxS, differences in PFAS blood, organ and excreta concentrations were observed over 120 h although linear dose responses were determined for area under the blood plasma time curves (AUC; PFOA, PFHxS), liver accumulation (LA: PFOS) and urinary excretion (UE; PFOA, PFHxS).

Predicting Type 2 Diabetes and Testosterone Effects in high-risk Australian men: Development and external validation of a 2 year risk model.

Objective: We have shown that men aged 50 years+ at high risk of type 2 diabetes treated with testosterone together with a lifestyle program reduced the risk of type 2 diabetes at two years by 40% compared to a lifestyle program alone. To develop a personalized approach to treatment, we aimed to explore a prognostic model for incident type 2 diabetes at two years and investigate biomarkers predictive of the testosterone effect.

Design: Model development in 783 men with impaired glucose tolerance but not type 2 diabetes from T4DM; a multicenter, 2-year trial of Testosterone vs placebo.

Outcomes of Debridement, Antibiotics, and Implant Retention in the Management of Infected Total Knee Arthroplasty: Analysis of 5,178 Cases from the National Australian Registry.

Introduction: Periprosthetic joint infection (PJI) is a devastating and severe complication of total knee arthroplasty (TKA). The Australian Joint Registry reports an increasing number of debridement, antibiotics, and implant retention (DAIR) procedures, underscoring the need to comprehend outcomes for informed treatment decisions. This study aimed to determine outcome of DAIR procedures, evaluate time since primary TKA, and identify patient-related factors associated with DAIR failure.

Asciminib add-on to imatinib demonstrates sustained high rates of ongoing therapy and deep molecular responses with prolonged follow-up in the ASC4MORE study.

Background: Up to 65% of patients with chronic myeloid leukemia (CML) who are treated with imatinib do not achieve sustained deep molecular response, which is required to attempt treatment-free remission. Asciminib is the only approved BCR::ABL1 inhibitor that Specifically Targets the ABL Myristoyl Pocket. This unique mechanism of action allows asciminib to be combined with adenosine triphosphate-competitive tyrosine kinase inhibitors to prevent resistance and enhance efficacy.

A systematic review of qualitative studies examining barriers and facilitators to orthopaedic surgeon engagement with patient-reported outcome measures data.

Background: Orthopaedic surgeon engagement with patient-reported outcome measures (PROMs) data has not been comprehensively evaluated, despite increasing uptake of orthopaedic PROMs programmes globally. The aim of this review was to systematically identify, appraise and synthesise qualitative evidence on barriers and facilitators to orthopaedic surgeons' engagement with PROMs data and their use of these data to support clinical practice.

Methods: Six databases (MEDLINE, EMBASE, COCHRANE CENTRAL, PSYCINFO, CINAHL and EMCARE) were searched from January 2000-March 2024 to identify potentially eligible qualitative studies.

Astrocytes contribute to toll-like receptor 2-mediated neurodegeneration and alpha-synuclein pathology in a human midbrain Parkinson's model.

Background: Parkinson's disease (PD) is characterised by degeneration of ventral midbrain dopaminergic (DA) neurons and abnormal deposition of α-synuclein (α-syn) in neurons. Activation of the innate immune pathogen recognition receptor toll-like receptor 2 (TLR2) is associated with exacerbation of α-syn pathology. TLR2 is increased on neurons in the PD brain, and its activation results in the accumulation and propagation of α-syn through autophagy inhibition in neurons.

Disinhibition across secondary motor cortical regions during motor sequence learning: A TMS-EEG study.

Secondary motor cortical regions, such as the supplementary motor area (SMA) are involved in planning and learning motor sequences, however the neurophysiological mechanisms across these secondary cortical networks remain poorly understood. In primary motor cortex, changes in excitatory and inhibitory neurotransmission (E:I balance) accompany motor sequence learning. In particular, there is an early reduction in inhibition (i.

Australian parents' attitudes, perceptions and supply of alcohol to adolescents: a national cross-sectional survey.

Parental supply of alcohol to adolescents is associated with increased risk of subsequent adolescent alcohol use and harms, so identifying factors associated with parents' decision-making is critical. This study examined how parental supply is associated with attitudes toward adolescent alcohol use, perceived norms of parental supply, perceived behavioural control and perceived acceptable age to drink alcohol. A total of 1197 Australian parents with children aged 12-17 years completed an online cross-sectional survey assessing their parental supply behaviours, attitudes and perceptions in April 2022.

Early Patient-Reported Outcome Measures Following Computer Navigated Total Hip Arthroplasty: A Study from the Australian Orthopaedic Association National Joint Replacement Registry.

Background: Total hip arthroplasty (THA) is a well-established treatment for symptomatic hip osteoarthritis (OA). The use of computer navigation in THA aims to achieve the reconstruction of the joint more consistently and precisely. The aim of this study was to contrast patient-reported outcome measures (PROMs) for THA procedures with and without commercially available navigation technologies.

The impact of fibre and prebiotic interventions on outcomes in cancer and haematopoietic stem cell transplantation: A systematic review.

Background & Aims: Cancer therapy is associated with a range of toxicities that severely impact patient well-being and a range of clinical outcomes. Dietary fibre/prebiotics characteristically improve the gastrointestinal microenvironment, which consequently elicits beneficial downstream effects that could be relevant to the prevention and management of treatment-related toxicities. Despite the compelling theoretical scientific rationale there has been limited effort to synthesise the available evidence to conclude such scientific underpinning to the clinical use of fibre/prebiotics in cancer patients.

Novel loci and biomedical consequences of iron homoeostasis variation.

Iron homoeostasis is tightly regulated, with hepcidin and soluble transferrin receptor (sTfR) playing significant roles. However, the genetic determinants of these traits and the biomedical consequences of iron homoeostasis variation are unclear. In a meta-analysis of 12 cohorts involving 91,675 participants, we found 43 genomic loci associated with either hepcidin or sTfR concentration, of which 15 previously unreported.
