Child-report food insecurity assessment measures: a scoping review.

Background: Experiences of household food insecurity are associated with a wide range of deleterious nutritional, developmental, psychological and social consequences for children. Children's distinct experiences of food insecurity, compared to adults, have been identified in diverse economic and cultural contexts. Yet historically, measurement of food insecurity in children has been predominantly reported by adult respondents on behalf of children, potentially underestimating prevalence and neglecting their unique perspectives.

Traumatic Tension Pneumothorax: A Tale of Two Pathologies.

Pneumothorax resulting from injury is a common phenomenon in both civilian and military trauma. A pneumothorax or simple pneumothorax is defined as air in the pleural space. A tension pneumothorax can evolve from a simple pneumothorax if there is a continued air leak from the lung without mechanism for egress.

Fulminant eosinophilic myocarditis and refractory ventricular arrhythmias requiring mechanical circulatory support: a case report.

Background: Fulminant eosinophilic myocarditis (EM) is a rare and often fatal condition that may present atypically and be complicated by ventricular arrhythmias. Treatment involves high-dose corticosteroids to suppress eosinophilia, as well as increasing use of mepolizumab, an anti-interleukin-5 antibody with evidence for long-term efficacy and safety.

Case Summary: A 38-year-old woman presented to the emergency department with neck pain and fatigue, and after extensive investigation was diagnosed with EM secondary to idiopathic hypereosinophilic syndrome.

Study Design: Retrospective cross-sectional study.

Setting, Participants: Cases of suspected myocarditis following the administration of a COVID-19 vaccine in Victoria during 22 February 2021 - 30 September 2022 reported to Surveillance of Adverse Events Following Vaccination In the Community (SAEFVIC), with symptom onset within 14 days of vaccination, and deemed to be confirmed myocarditis according to the Brighton Collaboration Criteria.

Halogen bonding BODIPY-appended pillar[5]arene for the optical sensing of dicarboxylates and a chemical warfare agent simulant.

A pillar[5]arene host, functionalised with halogen bonding (XB) recognition sites and BODIPY fluorophores, demonstrates strong binding and optical sensing of environmentally relevant dicarboxylates and a chemical warfare agent simulant, in organic and competitive aqueous-organic media - enabled by the unprecedented combination of fluorophore-conjugated XB interactions with the hydrophobic pillar[5]arene host cavity.

Intramedullary Total Femur via a Direct Anterior Approach for Complex Revision Total Hip and Knee Arthroplasty.

Total femur replacement is a well-recognized salvage procedure and an alternative to hip disarticulation in patients with massive femoral bone loss. Compared to conventional total femur replacement, intramedullary total femur (IMTF) requires less soft tissue dissection and preserves femoral bone stock and soft-tissue attachments. Despite these advantages, patients can still anticipate compromised functional outcomes and high complication rates following IMTF.

CSANZ and RANZCR Position Statement on Initial Certification and Maintenance of Recognition for Cardiac Magnetic Resonance Imaging (CMRI).

The CSANZ/RANZCR Position Statement on Cardiac Magnetic Resonance Imaging (CMRI) is intended to support and foster the provision of quality, safe CMRI services in Australia and New Zealand. This document specifically pertains to CMRI in adults, as distinct from general vascular MRI or paediatric imaging, and provides certification and recertification requirements.

Early Use of Aspirin for Coronary Allograft Prophylaxis in Heart Transplant Recipients.

Background: Coronary allograft vasculopathy (CAV) remains a significant cause of morbidity and mortality after heart transplantation. The use of aspirin for CAV prophylaxis has recently garnered interest as a possible therapeutic adjunct in this setting.

Methods: This 2-center retrospective cohort study included 372 patients who underwent heart transplantation between January 2009 and March 2018 and were stratified according to the commencement of aspirin during their index transplant admission.

Sharing Data from the Human Tumor Atlas Network through Standards, Infrastructure, and Community Engagement.

The Data Coordinating Center (DCC) of the Human Tumor Atlas Network (HTAN) has played a crucial role in enabling the broad sharing and effective utilization of HTAN data within the scientific community. Data from the first phase of HTAN are now available publicly. We describe the diverse datasets and modalities shared, multiple access routes to HTAN assay data and metadata, data standards, technical infrastructure and governance approaches, as well as our approach to sustained community engagement.

Examining the "revisability" benefit of hip resurfacing arthroplasty.

Background: Hip resurfacing arthroplasty (HRA) is an alternative to total hip arthroplasty (THA) that is typically reserved for young active patients because it preserves bone. However, the benefits of HRA only hold true if conversion THA after failed HRA provides acceptable outcomes.

Aim: To compare patient reported outcomes for conversion THA after HRA failure to primary THA.

Halogen bonding aza-BODIPYs for anion sensing and anion binding-modulated singlet oxygen generation.

Two novel aza-BODIPY based anion sensors, decorated with halogen bonding recognition sites, are capable of detecting halide anions at biologically-relevant near-IR wavelengths. With potential application for improving the selectivity of photodynamic therapy agents, unprecedented supramolecular host-guest anion binding-modulated singlet oxygen generation is demonstrated.

Epistasis, core-genome disharmony, and adaptation in recombining bacteria.

Recombination of short DNA fragments via horizontal gene transfer (HGT) can introduce beneficial alleles, create genomic disharmony through negative epistasis, and create adaptive gene combinations through positive epistasis. For non-core (accessory) genes, the negative epistatic cost is likely to be minimal because the incoming genes have not co-evolved with the recipient genome and are frequently observed as tightly linked cassettes with major effects. By contrast, interspecific recombination in the core genome is expected to be rare because disruptive allelic replacement is likely to introduce negative epistasis.

A spatiotemporal proteomic map of human adipogenesis.

White adipocytes function as major energy reservoirs in humans by storing substantial amounts of triglycerides, and their dysfunction is associated with metabolic disorders; however, the mechanisms underlying cellular specialization during adipogenesis remain unknown. Here, we generate a spatiotemporal proteomic atlas of human adipogenesis, which elucidates cellular remodelling as well as the spatial reorganization of metabolic pathways to optimize cells for lipid accumulation and highlights the coordinated regulation of protein localization and abundance during adipocyte formation. We identify compartment-specific regulation of protein levels and localization changes of metabolic enzymes to reprogramme branched-chain amino acids and one-carbon metabolism to provide building blocks and reduction equivalents.

A Halogen Bonding [2]Rotaxane Shuttle for Chloride-Selective Optical Sensing.

The first example of a [2]rotaxane shuttle capable of selective optical sensing of chloride anions over other halides is reported. The rotaxane was synthesised via a chloride ion template-directed cyclisation of an isophthalamide macrocycle around a multi-station axle containing peripheral naphthalene diimide (NDI) stations and a halogen bonding (XB) bis(iodotriazole) based station. Proton NMR studies indicate the macrocycle resides preferentially at the NDI stations in the free rotaxane, where it is stabilised by aromatic donor-acceptor charge transfer interactions between the axle NDI and macrocycle hydroquinone moieties.

No-Reflow Prediction in Acute Coronary Syndrome During Percutaneous Coronary Intervention: The NORPACS Risk Score.

Background: Suboptimal coronary reperfusion (no reflow) is common in acute coronary syndrome percutaneous coronary intervention (PCI) and is associated with poor outcomes. We aimed to develop and externally validate a clinical risk score for angiographic no reflow for use following angiography and before PCI.

Methods: We developed and externally validated a logistic regression model for prediction of no reflow among adult patients undergoing PCI for acute coronary syndrome using data from the Melbourne Interventional Group PCI registry (2005-2020; development cohort) and the British Cardiovascular Interventional Society PCI registry (2006-2020; external validation cohort).

HeartMate 3 implantation with an emphasis on the biventricular configuration.

Objectives: Right ventricular failure following implantation of a durable left ventricular assist device (LVAD) is a major driver of mortality. Reported survival following biventricular (BiVAD) or total artificial heart (TAH) implantation remains substantially inferior to LVAD alone. We report our outcomes with LVAD and BiVAD HeartMate 3 (HM3).

Light-driven nanoscale vectorial currents.

Controlled charge flows are fundamental to many areas of science and technology, serving as carriers of energy and information, as probes of material properties and dynamics and as a means of revealing or even inducing broken symmetries. Emerging methods for light-based current control offer particularly promising routes beyond the speed and adaptability limitations of conventional voltage-driven systems. However, optical generation and manipulation of currents at nanometre spatial scales remains a basic challenge and a crucial step towards scalable optoelectronic systems for microelectronics and information science.

Finasteride delays atherosclerosis progression in mice and is associated with a reduction in plasma cholesterol in men.

Finasteride is commonly prescribed to treat benign prostate hyperplasia and male-pattern baldness in cis men and, more recently, trans individuals. However, the effect of finasteride on cardiovascular disease remains elusive. We evaluated the role of finasteride on atherosclerosis using low-density lipoprotein (LDL) receptor-deficient (Ldlr) mice.
