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.

Short and Medium-Term Clinical and Radiographic Outcomes Following Arthroscopic Partial Wrist Arthrodeses - A Systematic Review.

Partial wrist arthrodesis (PWA) is a salvage procedure used in advanced wrist arthritis and has traditionally been performed via an open dorsal approach. In recent years, surgeons have moved towards arthroscopic fusions to minimise soft tissue damage and preserve vascular supply, increase union rates and hasten recovery. The purpose of this study is to synthesise the current literature on the outcomes of arthroscopic PWA.

Vascularized Bone Reconstruction for Recalcitrant Clavicular Nonunion: A Systematic Review of the Literature.

Purpose: Clavicular nonunion is an uncommon complication with a significant impact on quality of life and can be difficult to manage. In recalcitrant cases, or situations unfavorable for take of nonvascularized grafts, vascularized osseous reconstruction may be utilized. Several donor sites for such flaps have been described, with each associated with unique benefits and drawbacks.

Lumbar intervertebral disc replacement in Australia: An epidemiological study.

Introduction: Favorable short- and long-term outcomes have been reported for lumbar intervertebral total disc replacement (L-TDR). However, there is little evidence regarding the uptake of L-TDR in practice. The objective of this study was to analyze Australian-based population trends in L-TDR over the past 5 years.

Targeted Muscle Reinnervation Compared to Standard Peripheral Nerve Management Following Amputation: A Systematic Review and Meta-Analysis.

Background: Chronic pain remains a significant challenge for individuals following limb amputation, with incidence of painful neuromas, phantom limb pain (PLP), and residual limb pain (RLP). Targeted muscle reinnervation (TMR) is a surgical technique designed to restore motor control information lost during amputation by redirecting residual nerves to new muscle targets. This systematic review and meta-analysis aims to compare patient-reported and functional outcomes following amputation with either TMR or standard neurological treatment (SNT).

Increased Susceptibility of Cardiac Tissue to PM-Induced Toxicity in Uremic Cardiomyopathic Rats Is Linked to Elevated Levels of Mitochondrial Dysfunction.

Patients with chronic kidney disease (CKD) frequently develop uremic cardiomyopathy, characterized by mitochondrial dysfunction as one of its pathologically significant mediators. Given that PM specifically targets cardiac mitochondria, exacerbating toxicity, this study addresses the potential alterations in the severity of PM toxicity in the context of CKD conditions. Female Wistar rats were exposed to PM at a concentration of 250 μg/m daily for 3 h for 21 days after which an adenine-induced CKD model was developed.

Vascular supply of the radial nerve and its terminal branches: an anatomical study.

Purpose: The aim of this cadaveric study was to further describe the vascular supply of the radial, posterior interosseous and superficial radial nerves.

Methods: 11 cadaveric upper limbs, injected with colored latex, were dissected. Vascular afferents to the radial nerve, superficial radial nerve (SRN) and posterior interosseous nerve (PIN) were described and located.

Cascading spatial drought network: A complex networks approach to track propagation of meteorological droughts to agricultural droughts.

Meteorological droughts often propagate to agricultural (and other) droughts, both spatially and temporally. The present study proposes a novel complex networks-based cascading spatial drought network to examine the spatial propagation of meteorological droughts in a region to agricultural droughts in other regions. This is done through: (1) establishing stable homogeneous drought communities; (2) investigating inter-community drought propagation; (3) locating drought sources; and (4) evaluating drought connections within major crop belts.

Comparative evaluation of single and multiple exposure to PM in respirable air on cardiac physiology, structure and function in a Wistar rat model.

Many studies have shown the negative relationship between long term exposure to PM and cardiac dysfunction. Recently, studies have shown that even a single exposure of PM from air sample in permissible range can induce very mild cardiac pathological changes. In the present study, we revisited the toxic effect of PM on rat heart by adopting single and multiple exposure durations.

Arthroscopic Lunate Excision for Stage 3 Kienbock's Disease.

 The ideal treatment of stage 3 Kienbock's disease is uncertain, with current open procedures conferring the risk of carpal instability, ulnar translocation, and stiffness. We present our technique of arthroscopic lunate excision, and discuss our short- to medium-term results.  Via standard wrist arthroscopic portals, the lunate is excised using a combination of shavers, burrs, and rongeurs.

Data-driven drug treatment: enhancing clinical decision-making with SalpPSO-optimized GraphSAGE.

Safe drug recommendation systems play a crucial role in minimizing adverse drug reactions and enhancing patient safety. In this research, we propose an innovative approach to develop a safety drug recommendation system by integrating the Salp Swarm Optimization-based Particle Swarm Optimization (SalpPSO) with the GraphSAGE algorithm. The goal is to optimize the hyper parameters of GraphSAGE, enabling more accurate drug-drug interaction prediction and personalized drug recommendations.

The use of ultrasound to predict flexor tendinopathy after anterior locking plating of the distal radius.

This study compares ultrasound to clinical and radiographic measurements for assessing tendon pathology associated with distal radial anterior locking plates. A total of 46 patients undergoing removal of a distal radial plate had a preoperative clinical examination, radiographs and ultrasound evaluation to detect evidence of tendon irritation. Gross changes to the tendon were assessed during plate removal.

Rising rates of anterior cruciate ligament reconstruction in Australian adults: An analysis of Australian Medicare Benefits Schedule database.

Purpose: Anterior cruciate ligament (ACL) reconstruction is an evolving field, though there remains sparse epidemiological data on the treatment of ACL ruptures. The objective of this study is to analyse the trends in the rate of ACL reconstruction (ACLR) in adult patients over the past two decades in the Australian population.

Methods: The incidence of ACLR between 2001 and 2020 in patients 15 years and over was analysed using the Australian Medicare Benefits Schedule (MBS) database.

Streamflow Prediction Using Complex Networks.

The reliable prediction of streamflow is crucial for various water resources, environmental, and ecosystem applications. The current study employs a complex networks-based approach for the prediction of streamflow. The approach consists of three major steps: (1) the formation of a network using streamflow time series; (2) the calculation of the clustering coefficient (CC) as a network measure; and (3) the use of a clustering coefficient-based nearest neighbor search procedure for streamflow prediction.
