Abstract
Alzheimer's disease (AD) is associated with both extracellular amyloid-β (Aβ) plaques and intracellular tau-containing neurofibrillary tangles (NFT). We characterized the behavioral, metabolic and lipidomic phenotype of the 5xFADxTg30 mouse model which contains overexpression of both Aβ and tau. Our results independently reproduce several phenotypic traits described previously for this model, while providing additional characterization. This model develops many aspects associated with AD including frailty, decreased survival, initiation of aspects of cognitive decline and alterations to specific lipid classes and molecular lipid species in the plasma and brain. Notably, some sex-specific differences exist in this model and motor impairment with aging in this model does compromise the utility of the model for some movement-based behavioral assessments of cognitive function. These findings provide a reference for individuals interested in using this model to understand the pathology associated with elevated Aβ and tau or for testing potential therapeutics for the treatment of AD.

Abstract
A concise review is given on the past two decades' results from laboratory experiments on collisionless magnetic reconnection in direct relation with space measurements, especially by the Magnetospheric Multiscale (MMS) mission. Highlights include spatial structures of electromagnetic fields in ion and electron diffusion regions as a function of upstream symmetry and guide field strength, energy conversion and partitioning from magnetic field to ions and electrons including particle acceleration, electrostatic and electromagnetic kinetic plasma waves with various wavelengths, and plasmoid-mediated multiscale reconnection. Combined with the progress in theoretical, numerical, and observational studies, the physics foundation of fast reconnection in collisionless plasmas has been largely established, at least within the parameter ranges and spatial scales that were studied. Immediate and long-term future opportunities based on multiscale experiments and space missions supported by exascale computation are discussed, including dissipation by kinetic plasma waves, particle heating and acceleration, and multiscale physics across fluid and kinetic scales.

Abstract
Sex is a significant source of heterogeneity in schizophrenia, with more negative symptoms in males and more affective symptoms and internalizing comorbidity in females. In this narrative review, we argue that there are likely sex differences in the pathophysiological mechanisms of schizophrenia-spectrum disorders (SZ) that originate during puberty and relate to the sex-specific impacts of pubertal maturation on brain development. Pubertal maturation might also trigger underlying (genetic or other) vulnerabilities in at-risk individuals, influencing brain development trajectories that contribute to the emergence of SZ. This review is the first to integrate links between pubertal development and neural development with cognitive neuroscience research in SZ to form and evaluate these hypotheses, with a focus on the frontal-striatal and frontal-limbic networks and their hypothesized contribution to negative and mood symptoms respectively. To test these hypotheses, longitudinal research with human adolescents is needed that examines the role of sex and pubertal development using large cohorts or high risk samples. We provide recommendations for such studies, which will integrate the fields of psychiatry, developmental cognitive neuroscience, and developmental endocrinology towards a more nuanced understanding of the role of pubertal factors in the hypothesized sex-specific pathophysiological mechanisms of schizophrenia.

Abstract
Under quasi-radial interplanetary magnetic fields (IMF), foreshock turbulence can have an impact on the magnetosheath and cusps depending on the location of the quasi-parallel shock. We perform three-dimensional simulations of Earth's dayside magnetosphere using the hybrid code HYPERS, and compare northward and southward quasi-radial IMF configurations. We study the magnetic field configuration, fluctuations in the magnetosheath and the plasma in the regions around the northern cusp. Under northward IMF with Earthward B x , there is a time-varying plasma depletion layer immediately outside the northern cusp. In the southward IMF case, the impact of foreshock turbulence and high-speed jets, together with magnetopause reconnection, can lead to strong density enhancements in the cusp.

Abstract
OBJECTIVE To determine the incidence and characteristics of wound healing complications after folded flap palatoplasty (FFP). METHODS Prospective study of 25 dogs that underwent FFP as a component of corrective multilevel surgery for brachycephalic obstructive airway syndrome. Oropharyngeal re-examination was conducted after a minimum of 28 days post-operatively, unless indicated earlier by the onset of clinical signs. RESULTS Wound healing complications occurred in nine dogs (36%). Minor and major wound complications were diagnosed at a median of 36 days (1.5-51 days) post-operatively. Eight dogs had major wound complications, four of which showed no associated clinical signs. Two patterns of major wound complications were observed: incisional dehiscence (ID) with caudal retraction of the soft palate mucosa and development of a full-thickness defect (FTD) in the centre of the soft palate. Revision of the soft palate surgery was performed in five dogs, failing again in one dog with ID. Clinical signs resolved in symptomatic dogs after revision surgery to close FTD. CONCLUSION In this study, wound healing complications were common after FFP and were not associated with significant clinical deterioration. Further research is necessary to determine the value and timing of routine post-operative oropharyngeal examination for assessment of soft palate healing after FFP as well as the indication for and success of approaches to the management of wound healing complications. The two distinct patterns of FFP failure recognised may provide insight into the underlying causes and lead to refinements in folded flap palatoplasty technique.

Abstract
Magnetic reconnection has been observed in the transition region of quasi-parallel shocks. In this work, the particle-in-cell method is used to simulate three-dimensional reconnection in a quasi-parallel shock. The shock transition region is turbulent, leading to the formation of reconnecting current sheets with various orientations. Two reconnection sites with weak and strong guide fields are studied, and it is shown that reconnection is fast and transient. Reconnection sites are characterized using diagnostics including electron flows and magnetic flux transport. In contrast to two-dimensional simulations, weak guide field reconnection is realized. Furthermore, the current sheets in these events form in a direction almost perpendicular to those found in two-dimensional simulations, where the reconnection geometry is constrained.

Abstract
Improving wastewater treatment processes is becoming increasingly important, due to more stringent effluent quality requirements, the need to reduce energy consumption and chemical dosing. This can be achieved by applying artificial intelligence. Machine learning is implemented in two domains: (1) predictive control and (2) advanced analytics. This is currently being piloted at the integrated validation plant of PUB, Singapore's National Water Agency. (1) Primarily, predictive control is applied for optimised nutrient removal. This is obtained by application of a self-learning feedforward algorithm, which uses load prediction and machine learning, fine-tuned with feedback on ammonium effluent. Operational results with predictive control show that the load prediction has an accuracy of ≈88%. It is also shown that an up to ≈15% reduction of aeration amount is achieved compared to conventional control. It is proven that this load prediction-based control leads to stable operation and meeting effluent quality requirements as an autopilot system. (2) Additionally, advanced analytics are being developed for operational support. This is obtained by application of quantile regression neural network modelling for anomaly detection. Preliminary results illustrate the ability to autodetect process and instrument anomalies. These can be used as early warnings to deliver data-driven operational support to process operators.

Abstract
Abstract
Background
The Australian National Bowel Cancer Screening Program (NBSCP) is a free population-based screening program which aims to identify precancerous lesions and early colorectal cancer (CRC) using an immunochemical faecal occult blood test in average risk Australians. Formally commencing in 2006, NBCSP participation rate in eligible 50-74-year-old people was 42% in 2018. The barriers and facilitators of participation in the NBCSP have been explored for the general, at-risk population but not in a population of CRC patients. This is the first study to assess a population of CRC patients, post diagnosis, who would have been eligible for CRC screening to determine the barriers and facilitators to screening.
Methods
A cross sectional study nested within a cohort study. Data from CRC patients who participated in the 45 and Up Study; the largest cohort study in Australia and southern hemisphere, were analysed to compare those who had and had not participated in CRC screening. Logistic regression analyses were conducted using RStudio (version 3.5.2, Boston, Massachusetts, USA.). Multiple Imputation (MI), was used to handle missing values assumed to be missing at random.
Results
A total of 339 CRC patients were included. Patients who were female, overweight (≥25kg/m2), consumed less than the recommended five servings of vegetables per day, consumed less than or equal to fourteen standard drinks per week (compared to non-drinkers) or did not meet physical activity guidelines were significantly less likely to have participated in screening.
Conclusions
Our study has taken a unique approach to identifying a high-risk group by exploring factors to screening participation in CRC patients. CRC patients with less healthy lifestyles were less likely to participate in screening. In contrast to previous studies, female patients were less likely to participate in screening than males were. This was an unexpected finding and should be replicated.
Key messages
Not surprising that those with less healthy lifestyle practices also reflected less than ideal screening practices. Surprising that female patients participated less in screening than males. Future interventions to improve CRC screening participation rates should consider specialised messaging for average-risk females who are overweight not meeting dietary or physical activity guidelines.

Abstract
We report measurements of lower-hybrid drift waves driving electron heating and vortical flows in an electron-scale reconnection layer under a guide field. Electrons accelerated by the electrostatic potential of the waves exhibit perpendicular and nongyrotropic heating. The vortical flows generate magnetic field perturbations comparable to the guide field magnitude. The measurements reveal a new regime of electron-wave interaction and how this interaction modifies the electron dynamics in the reconnection layer.

Abstract
Aided by fully kinetic simulations, spacecraft observations of magnetic reconnection in Earth's magnetotail are analyzed. The structure of the electron diffusion region is in quantitative agreement with the numerical model. Of special interest, the spacecraft data reveal how reconnection is mediated by off-diagonal stress in the electron pressure tensor breaking the frozen-in law of the electron fluid.

Abstract
INTRODUCTION This study aimed to review the literature to establish whether there is a best treatment for low-risk ankle fractures in children. MATERIALS AND METHODS A systematic review and meta-analysis of trials was undertaken, which compared interventions for 'low-risk' ankle fractures in children. A meta-analysis was performed using a random effects model. RESULTS Four trials were identified reporting outcomes from 256 patients. All trials reported results using a device that permitted ankle motion compared with more rigid immobilisation. Overall risk of bias was low for three trials and high for one trial. Two trials assessed time to return to normal function. Patients treated in a splint or with a bandage recovering 6-7.5 days sooner than those treated with rigid immobilisation. One trial demonstrated that children returned to school sooner if treated in a bandage rather than in a cast. Two trials found a higher Activity Scale for Kids performance score at four weeks for children treated with splint compared with rigid immobilisation. There was no clear advantage to any device in patient satisfaction, quality of life or total costs. DISCUSSION There is no clear best treatment for these injuries. Studies had significant limitations and outcomes were heterogeneous, limiting meta-analysis. CONCLUSION There is a need for a definitive trial to establish the best treatment for ankle fractures and a core outcome set to ensure study findings are consistent and can be analysed in future meta-analyses.

Abstract
OBJECTIVES To describe the spectrum of movement disorders and cerebrospinal fluid (CSF) neurotransmitter profiles in paediatric patients with POLG disease. METHODS We identified children with genetically confirmed POLG disease, in whom CSF neurotransmitter analysis had been undertaken. Clinical data were collected retrospectively. CSF neurotransmitter levels were compared to both standardised age-related reference ranges and to non-POLG patients presenting with status epilepticus. RESULTS Forty-one patients with POLG disease were identified. Almost 50% of the patients had documented evidence of a movement disorder, including non-epileptic myoclonus, choreoathetosis and ataxia. CSF neurotransmitter analysis was undertaken in 15 cases and abnormalities were seen in the majority (87%) of cases tested. In many patients, distinctive patterns were evident, including raised neopterin, homovanillic acid and 5-hydroxyindoleacetic acid levels. CONCLUSIONS Children with POLG mutations can manifest with a wide spectrum of abnormal movements, which are often prominent features of the clinical syndrome. Underlying pathophysiology is probably multifactorial, and aberrant monoamine metabolism is likely to play a role.

Abstract
Zoledronic acid (zoledronate) is a bisphosphonate used predominantly as a second-line treatment for post-menopausal osteoporosis. Its administration is associated with an acute phase reaction. Here, we present two cases of anterior uveitis following initial administration of zoledronate. In the first case, an 80-year-old lady presented with right eye pain and decreased visual acuity 24-hours post-infusion. Uveitis was diagnosed and sub-conjunctival injection of corticosteroids was required. In the second case, a 78-year-old lady presented with right eye pain, vomiting and decreased acuity 24-hours after infusion. She was treated with topical steroids and required cataract surgery to normalise visual acuity. Patients prescribed zoledronate should be warned of the risk of ocular side effects and asked to report promptly for treatment if they develop a red, painful eye or blurred vision.

Abstract
We performed a prospective clinical audit in hospitalised patients with suspected pulmonary tuberculosis (PTB) with the objective of evaluating the accuracy and clinical utility of Xpert® MTB/RIF in induced sputum in an intermediate-burden setting. Of 450 patients audited, 61 (13.6%) were diagnosed with PTB based on positive culture. The sensitivity, specificity and positive and negative predictive values for Xpert in smear-negative cases for induced sputum were respectively 75%, 99.5%, 94.7% and 97.0%. Xpert in induced sputum may facilitate diagnostic yield and expedite treatment in up to a quarter of PTB patients.

Abstract
A much larger sample (N = 2369) was used to evaluate a previously reported distribution of the A, AB and B blood group phenotypes in rhesus and cynomolgus macaques from six different regional populations. These samples, acquired from 15 different breeding and research facilities in the United States, were analyzed using a real-time quantitative polymerase chain reaction (qPCR) assay that targets single nucleotide polymorphisms (SNPs) responsible for the macaque A, B and AB phenotypes. The frequency distributions of blood group phenotypes of the two species differ significantly from each other and significant regional differentiation within the geographic ranges of each species was also observed. The B blood group phenotype was prevalent in rhesus macaques, especially those from India, while the frequencies of the A, B and AB phenotypes varied significantly among cynomolgus macaques from different geographic regions. The Mauritian cynomolgus macaques, despite having originated in Indonesia, showed significant (P ≪ .01) divergence from the Indonesian animals at the ABO blood group locus. Most Mauritian animals belonged to the B blood group while the Indonesian animals were mostly A. The close similarity in blood group frequency distributions between the Chinese rhesus and Indochinese cynomolgus macaques demonstrates that the introgression between these two species extends beyond the zone of intergradation in Indochina. This study underscores the importance of ABO blood group phenotyping of the domestic supply of macaques and their biospecimens.
