Purpose: To investigate the changes in match demands of Australian Football League Women's (AFLW) athletes over the past 3 seasons (2022-2023). It was hypothesized that match demands would increase across all positional groups.

Methods: Forty-two athletes from 1 AFLW club who played at least 1 match across seasons 6 to 8 (2022-2023) were included.

Revision Hip Arthroplasty Through a Gluteal-Sparing Extended Posterior Approach May be Able to Achieve Similar Functional Outcomes to Primary Hip Arthroplasty.

Background: Revision total hip arthroplasty (THA) has been reported to have worse outcomes when compared to primary procedures, which may, in part, be due to the increased exposure required for the procedure. We aimed to investigate the postoperative functional outcomes of 2 groups of primary and revision THA, when revision procedures were performed using a gluteal-sparing extended posterior approach.

Methods: Two groups of 51 primary and 21 revision THAs were prospectively recruited from a single center between 2016 and 2019.

Precursor Identity and Surfactant Concentration Influence Shape of UO Nanoparticles.

A fundamental step toward studying the unique properties of actinide nanomaterials is control over the shape of actinide nanoparticles. Toward this goal, this work demonstrates the effects of precursor identity and surfactant concentration on the shape of uranium dioxide (UO) nanoparticles. UO nanoparticles were synthesized by thermal decomposition of different precursors in the presence of oleylamine and oleic acid as surfactants.

Stepping toward implementation using co-design: development of hospital protocols and resources for using wearable activity trackers in a hospital service.

Introduction: Low levels of patient physical activity during a hospital stay are linked to a variety of poor outcomes. Wearable activity trackers can help to boost patient activity and improve other outcomes during a hospitalisation, but a range of implementation barriers exist. Co-design research methodologies provide opportunities to bridge evidence-practice gaps, such as the implementation of wearable activity trackers to promote patient activity, by developing solutions and strategies in collaboration with key stakeholders.

What outcomes are important to people with foot and ankle disorders in rheumatic and musculoskeletal diseases? An OMERACT qualitative interview study across four continents.

Background: The foot and ankle are frequently affected in rheumatic and musculoskeletal diseases (RMDs), yet there is a lack of high-quality evidence to determine the effectiveness of treatments. Outcomes in research are often inconsistently measured, impeding evidence synthesis. Additionally, clinical decisions are based on research outcomes, but these are not always regarded as important by people with RMDs.

Berkelium-carbon bonding in a tetravalent berkelocene.

Interest in actinide-carbon bonds has persisted since actinide organometallics were first investigated for applications in isotope separation during the Manhattan Project. Transplutonium organometallics are rarely isolated and structurally characterized, likely owing to limited isotope inventories, a scarcity of suitable laboratory infrastructure, and intrinsic difficulties with the anaerobic conditions required. Herein, we report the discovery of an organometallic "berkelocene" complex prepared from 0.

Plasma Microbial Cell-free DNA Sequencing for the Detection of Kingella kingae Pediatric Spinal Infections.

Background: Diagnosis of Kingella kingae skeletal system infections is made challenging by the microbe's fastidious nature. Detection and quantification of circulating microbial cell-free DNA (mcfDNA) in plasma by the Karius Test, a commercial metagenomic sequencing test, may offer promise in diagnosing pediatric spinal infections caused by difficult-to-culture organisms such as K. kingae .

Real-world implementation of pain science education and barriers to use in private practice physiotherapy settings: an Australia-wide cross-sectional survey.

Physiotherapists are critically positioned to integrate education into patient care, including pain science education (PSE) to enhance management and outcomes. Anecdotally, many physiotherapists report difficulty providing PSE in private practice settings. Here, we aimed to explore current PSE use, knowledge, and barriers to implementation.

Synthesis and characterization of isostructural annulated actinocenes.

An isostructural series of four annulated actinocene complexes, M(hdcCOT) (M = Th, U, Np, Pu), is reported. The syntheses proceed through a trivalent starting material when M = U, Np, Pu with subsequent oxidation or, in the case of M = Th, directly from ThCl(DME). X-ray crystallography shows that each actinocene has molecular point symmetry in the solid state, with the metal atoms symmetrically bonded to two 10π-aromatic [8]annulene dianion rings.

Association between clinical and MRI-detected imaging findings for people with midfoot pain, a cross-sectional study.

Background: Midfoot pain is common but poorly understood, with radiographs often indicating no anomalies. This study aimed to describe bone, joint and soft tissue changes and to explore associations between MRI-detected abnormalities and clinical symptoms (pain and disability) in a group of adults with midfoot pain, but who were radiographically negative for osteoarthritis.

Methods: Community-based participants with midfoot pain underwent an MRI scan of one foot and scored semi-quantitatively using the Foot OsteoArthritis MRI Score (FOAMRIS).

Synthesis, Structure, and Bonding of Actinide-Rhenium Polyhydrides.

The synthesis of actinide tetrarhenate complexes completes a series of iridate, osmate, and rhenate polyhydrides, allowing for structural and bonding comparisons to be made. Computational studies examine the bonding interactions, particularly between metals, in these complexes. Several factors─including metal oxidation state, coordination number, and dispersion effects─affect metal-metal distances and covalency in these actinide tetrametallates.

Reduction of CS to an ethanetetrathiolate by a hydride-bridged uranium-iridium heterobimetallic complex.

We report the synthesis of a heterobimetallic U(III)-Ir species which reacts with CS to form the novel ethanetetrathiolate fragment hydride insertion and C-C coupling. Computational studies suggest the formation of a radical intermediate, which may couple with another equivalent to form the final product.

The Cumulative Impacts of Fatigue during Overload Training Can Be Tracked Using Field-Based Monitoring of Running Stride Interval Correlations.

Integrating running gait coordination assessment into athlete monitoring systems could provide unique insight into training tolerance and fatigue-related gait alterations. This study investigated the impact of an overload training intervention and recovery on running gait coordination assessed by field-based self-testing. Fifteen trained distance runners were recruited to perform 1-week of light training (baseline), 2 weeks of heavy training (high intensity, duration, and frequency) designed to overload participants, and a 10-day light taper to allow recovery and adaptation.

The Counterintuitive Relationship between Orbital Energy, Orbital Overlap, and Bond Covalency in CeF and CeCl.

The 4f orbitals of Ce(IV) have shown appreciably enhanced covalent mixing with ligand orbitals relative to those of Ce(III). Here, X-ray spectroscopy, magnetic susceptibility measurements, and theoretical methods are used to investigate 4f covalency in CeF and CeCl. These techniques show covalent mixing between Ce 4f and F 2p orbitals to be about 25% less than mixing between Ce 4f and Cl 3p orbitals, placing CeF among the most ionic Ce(IV) compounds to-date.

Making the grade? A meta-analysis of academic performance as a predictor of work performance and turnover.

Many organizations assess job applicants' academic performance (AP) when making selection decisions. However, researchers and practitioners recently have suggested that AP is not as relevant to work behavior as it used to be due to factors such as grade inflation and increased differences between academic and work contexts. The present meta-analysis examines whether, and under what conditions, AP is a useful predictor of work behavior.

Formation of uranium disulfide from a uranium thioamidate single-source precursor.

A single-source-precursor approach was developed to synthesize uranium-based materials outside of the typically-studied oxides. This approach allows for shorter reaction times, milder reaction conditions, and control over the chemicals present in synthesis. To this end, the first homoleptic uranium thioamidate complex was synthesized as a precursor for US materials.

Establishing a Consensus-Based Framework for the Use of Wearable Activity Trackers in Health Care: Delphi Study.

Background: Physical activity (PA) plays a crucial role in health care, providing benefits in the prevention and management of many noncommunicable diseases. Wearable activity trackers (WATs) provide an opportunity to monitor and promote PA in various health care settings.

Objective: This study aimed to develop a consensus-based framework for the optimal use of WATs in health care.

Analyzing the Intensities of K-Edge Transitions in X Molecules (X = F, Cl, Br) for Use in Ligand K-Edge X-ray Absorption Spectroscopy.

Ligand K-edge X-ray absorption spectroscopy (XAS) is regularly used to determine the ligand contribution to metal-ligand bonds. For quantitative studies, the pre-edge transition intensities must be referenced to an intensity standard, and pre-edge intensities obtained from different ligand atoms cannot be compared without standardization due to different cross sections at each absorption edge. In this work, the intensities of the 1s → σ* transitions in F, Cl, and Br are analyzed for their use as references for ligand K-edge XAS.

CO cleavage by tantalum/M (M = iridium, osmium) heterobimetallic complexes.

A novel Ta/Os heterobimetallic complex, [Ta(CHBu)(μ-H)OsCp*], 2, is prepared by protonolysis of Ta(CHBu)(CHBu) with Cp*OsH. Treatment of 2 and its iridium analogue [Ta(CHBu)(μ-H)IrCp*], 1, with CO under mild conditions reveal the efficient cleavage of CO, driven by the formation of a tantalum oxo species in conjunction with CO transfer to the osmium or iridium fragments, to form Cp*Ir(CO)H and Cp*Os(CO)H, respectively. This bimetallic reactivity diverges from more classical CO insertion into metal-X (X = metal, hydride, alkyl) bonds.
