Abstract
BACKGROUND AND AIMS The American Society for Gastrointestinal Endoscopy (ASGE) AI Task Force along with experts in endoscopy, technology space, regulatory authorities, and other medical subspecialties initiated a consensus process that analyzed the current literature, highlighted potential areas, and outlined the necessary research in artificial intelligence (AI) to allow a clearer understanding of AI as it pertains to endoscopy currently. METHODS A modified Delphi process was used to develop these consensus statements. RESULTS Statement 1: Current advances in AI allow for the development of AI-based algorithms that can be applied to endoscopy to augment endoscopist performance in detection and characterization of endoscopic lesions. Statement 2: Computer vision-based algorithms provide opportunities to redefine quality metrics in endoscopy using AI, which can be standardized and can reduce subjectivity in reporting quality metrics. Natural language processing-based algorithms can help with the data abstraction needed for reporting current quality metrics in GI endoscopy effortlessly. Statement 3: AI technologies can support smart endoscopy suites, which may help optimize workflows in the endoscopy suite, including automated documentation. Statement 4: Using AI and machine learning helps in predictive modeling, diagnosis, and prognostication. High-quality data with multidimensionality are needed for risk prediction, prognostication of specific clinical conditions, and their outcomes when using machine learning methods. Statement 5: Big data and cloud-based tools can help advance clinical research in gastroenterology. Multimodal data are key to understanding the maximal extent of the disease state and unlocking treatment options. Statement 6: Understanding how to evaluate AI algorithms in the gastroenterology literature and clinical trials is important for gastroenterologists, trainees, and researchers, and hence education efforts by GI societies are needed. Statement 7: Several challenges regarding integrating AI solutions into the clinical practice of endoscopy exist, including understanding the role of human-AI interaction. Transparency, interpretability, and explainability of AI algorithms play a key role in their clinical adoption in GI endoscopy. Developing appropriate AI governance, data procurement, and tools needed for the AI lifecycle are critical for the successful implementation of AI into clinical practice. Statement 8: For payment of AI in endoscopy, a thorough evaluation of the potential value proposition for AI systems may help guide purchasing decisions in endoscopy. Reliable cost-effectiveness studies to guide reimbursement are needed. Statement 9: Relevant clinical outcomes and performance metrics for AI in gastroenterology are currently not well defined. To improve the quality and interpretability of research in the field, steps need to be taken to define these evidence standards. Statement 10: A balanced view of AI technologies and active collaboration between the medical technology industry, computer scientists, gastroenterologists, and researchers are critical for the meaningful advancement of AI in gastroenterology. CONCLUSIONS The consensus process led by the ASGE AI Task Force and experts from various disciplines has shed light on the potential of AI in endoscopy and gastroenterology. AI-based algorithms have shown promise in augmenting endoscopist performance, redefining quality metrics, optimizing workflows, and aiding in predictive modeling and diagnosis. However, challenges remain in evaluating AI algorithms, ensuring transparency and interpretability, addressing governance and data procurement, determining payment models, defining relevant clinical outcomes, and fostering collaboration between stakeholders. Addressing these challenges while maintaining a balanced perspective is crucial for the meaningful advancement of AI in gastroenterology.

Abstract
The lower hybrid drift wave (LHDW) has been a candidate for anomalous resistivity and electron heating inside the electron diffusion region of magnetic reconnection. In a laboratory reconnection layer with a finite guide field, quasielectrostatic LHDW (ES-LHDW) propagating along the direction nearly perpendicular to the local magnetic field is excited in the electron diffusion region. ES-LHDW generates large density fluctuations (δn_{e}, about 25% of the mean density) that are correlated with fluctuations in the out-of-plane electric field (δE_{Y}, about twice larger than the mean reconnection electric field). With a small phase difference (∼30°) between two fluctuating quantities, the anomalous resistivity associated with the observed ES-LHDW is twice larger than the classical resistivity and accounts for 20% of the mean reconnection electric field. After we verify the linear relationship between δn_{e} and δE_{Y}, anomalous electron heating by LHDW is estimated by a quasilinear analysis. The estimated electron heating is about 2.6±0.3 MW/m^{3}, which exceeds the classical Ohmic heating of about 2.0±0.2 MW/m^{3}. This LHDW-driven heating is consistent with the observed trend of higher electron temperatures when the wave amplitude is larger. Presented results provide the first direct estimate of anomalous resistivity and electron heating power by LHDW, which demonstrates the importance of wave-particle interactions in magnetic reconnection.

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
CLINICAL RELEVANCE Interpersonal skills are crucial for successful clinician-patient interactions. To prepare future optometrists for clinical practice, pedagogical evaluation is important to support the implementation of new strategies for teaching and evaluating interpersonal skills. BACKGROUND Optometry students largely develop their interpersonal skills through in-person patient interactions. Telehealth is increasing, yet strategies to develop the interpersonal skills of students for teleconsulting have not been explored. This study aimed to assess the feasibility, effectiveness and perceived usefulness of an online, multisource (patients, clinicians and students) evaluation and feedback program for developing interpersonal skills. METHODS Via an online teleconferencing platform, optometry students (n = 40) interacted with a volunteer patient, observed by a teaching clinician. Patients and clinicians evaluated the interpersonal skills of the student in two ways: (1) qualitative written feedback, and (2) quantitative rating (Doctors' Interpersonal Skills Questionnaire). All students received written patient and clinician feedback after the session, but not their quantitative ratings. A subset of students (n = 19) completed two sessions, self-ratings, and were provided with their written feedback and an audiovisual recording from their first interaction before completing the second session. All participants were invited to complete an anonymous survey at program completion. RESULTS Patient and clinician overall interpersonal skills ratings were positively correlated (Spearman's r = 0.35, p = 0.03) and showed moderate agreement (Lin's concordance coefficient = 0.34). Student self-ratings did not match patient ratings (r = 0.01, p = 0.98), whereas there was moderate agreement between clinician and student ratings (Lin's concordance coefficient = 0.30). Ratings improved at the second visit (p = 0.01). Patient ratings were higher than clinicians (p = 0.01) and students (p = 0.03). All participants agreed that the program was feasible, useful and effective at fostering good interpersonal skills. CONCLUSION Multisource feedback about interpersonal skills contributes to improvement in student performance. Patients and clinicians can evaluate and provide useful feedback to optometry students about their interpersonal skills using online methods.

Abstract
There is rapidly increasing uptake of GLP-1 (glucagon-like peptide-1) agonists such as semaglutide worldwide for weight loss and management of non-alcoholic steatohepatitis (NASH). remains a paucity of safety data in the vulnerable NASH cirrhotic population. We report herein the first documented case of liver decompensation and need for liver transplant waitlisting in a patient with NASH-cirrhosis treated with semaglutide. Rapid weight loss led to the development of ascites and hepatic encephalopathy and an increase in the patients Model for Endstage Liver Disease-Na (MELD-Na) score from 11 to 22. Aggressive nutritional supplementation was commenced and the semaglutide was stopped. Over the following months she regained her weight and her liver recompensated and her MELD-Na decreased to 13, allowing her to be delisted from the transplant waitlist. This case serves as a cautionary tale to clinicians using semaglutide in the cirrhotic population and highlights the need for more safety data in this patient group.

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
BACKGROUND Over the last decade, the treatment landscape for moderate-severe psoriasis has rapidly evolved. The Australasian College of Dermatologists sought to review and update previously published treatment goals for moderate-severe psoriasis. METHODS A modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7-9 on a 9-point scale (1 strongly disagree; 9 strongly agree). RESULTS Consensus was achieved on 26/29 statements in round 1 and a further 20 statements in round 2. There was strong agreement to expanding the classification/definition of psoriasis severity by including a choice of metrics, incorporating quality of life measures, and widening the scope of high-impact sites. Consensus was also reached on revised treatment response criteria, which were then incorporated into a new treatment algorithm. There was discordance with the current requirement to undertake a trial with established systemic agents before accessing targeted therapy. CONCLUSION The ability of new targeted treatment options to change the narrative in psoriasis patient care can only be properly realised if challenges to timely and equitable access are addressed. The proposed framework for the assessment, classification and management of moderate-severe psoriasis aligns with international recommendations. Its adoption into Australian clinical practice is hoped to improve treatment outcomes and patients' satisfaction with their care.

Abstract
Background and Aim Obtaining endoscopic biopsies from the ampulla of Vater is important for the diagnosis of lesions that are suspicious for neoplasia. The clinical safety profile is not well defined in the literature. Our aim was to evaluate the procedure-related readmission rate and complications from ampullary biopsy in patients undergoing duodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP). Methods A retrospective data analysis was performed on adult patients at Austin Hospital who underwent ampullary biopsies between 1 January 2010 and 1 March 12022. Medical records were identified using pathology databases. The electronic health record was reviewed for baseline characteristics including demographics, date, indication for ampullary biopsy, procedure type (duodenoscopy or ERCP), and procedural associated interventions during ERCP. Readmissions to the Austin Emergency Department within 30 days following the biopsy were identified, and complications were noted. Results A total of 506 records were reviewed and 246 episodes of ampullary biopsy met the inclusion criteria. The procedure-related readmission rate for all episodes was 6.1%, which included pain (3.3%), pancreatitis (2.0%), cholangitis (1.6%), and bleeding (0.8%). Ampullary biopsies with ERCP had a procedure-related readmission rate of 8.4%, whereas ampullary biopsies without ERCP had a rate of 2.2%. Increased readmissions and complications were associated with male sex (P = 0.01 and P = 0.05, respectively). There was no association between the number of biopsies taken and complications. Conclusion Performing an ampullary biopsy without an associated ERCP carries a low rate of clinical complications and procedure-related readmissions. The combination of ERCP and ampullary biopsy increases the risk four-fold.

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
Background and Aim During COVID-19, restrictions to elective endoscopy were introduced worldwide. A reduction in procedures may impact trainees' endoscopy learning. This study aims to assess Australian advanced gastroenterology and general surgery trainees' self-perceived efficacy and knowledge in endoscopy during the pandemic. Methods All Australian gastroenterology and general surgery trainees in their last 2 years of accredited training were invited to participate through email (2020-2021 and 2021-2022 training cycles). The primary outcome was to assess trainees' self-efficacy and knowledge regarding gastrointestinal endoscopy. Secondary outcomes included subgroup analysis between gastroenterology and general surgery trainees. Self-perceived efficacy was assessed with Likert-scale questions on 20 endoscopy procedures and knowledge was assessed through 21 endoscopy-related multiple choice questions. Results Eighty-one trainees responded to a self-efficacy questionnaire and 77 responded to the knowledge questionnaire. Over 90% of the trainees were confident or extremely confident in diagnostic endoscopy, but only half demonstrated similar efficacy for therapeutic endoscopy. The efficacy for basic endoscopy procedures was higher for gastroenterology trainees (64.0% vs 51.1%, P < 0.001). Last-year trainee achievement of conjoint committee requirements for upper gastrointestinal endoscopy was achieved in 95.8% of gastroenterology trainees versus 22.2% of surgical trainees (P < 0.001). The median score on the knowledge questionnaire was also higher for the gastroenterology subset (90.5% vs 71.4%, P < 0.001). Conclusion During COVID-19, endoscopy trainees' self-efficacy in endoscopic diagnostic procedures was achieved for most trainees. The differences in self-perceived efficacy and knowledge between gastroenterology and surgical trainees may be reflective of the different opportunities for learning between the two groups.

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
The intrinsic temporal nature of magnetic reconnection at the magnetopause has been an active area of research. Both temporally steady and intermittent reconnection have been reported. We examine the steadiness of reconnection using space-ground conjunctions under quasi-steady solar wind driving. The spacecraft suggests that reconnection is first inactive, and then activates. The radar further suggests that after activation, reconnection proceeds continuously but unsteadily. The reconnection electric field shows variations at frequencies below 10 mHz with peaks at 3 and 5 mHz. The variation amplitudes are ∼10-30 mV/m in the ionosphere, and 0.3-0.8 mV/m at the equatorial magnetopause. Such amplitudes represent 30%-60% of the peak reconnection electric field. The unsteadiness of reconnection can be plausibly explained by the fluctuating magnetic field in the turbulent magnetosheath. A comparison with a previous global hybrid simulation suggests that it is the foreshock waves that drive the magnetosheath fluctuations, and hence modulate the reconnection.

Abstract
Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth-sized indents. Both the interplanetary magnetic field (IMF) and solar wind are constant in our simulation, and hence, all dynamics are generated by foreshock instabilities. The IMF in the simulation is mostly Sun-Earth aligned with a weak northward and zero dawn-dusk component, such that subsolar magnetopause reconnection is not expected without foreshock turbulence modifying the magnetosheath fields. We show a reconnection example to illustrate that the turbulence can create large magnetic shear angles across the magnetopause to induce local bursty reconnection. Magnetopause reconnection and indents developed from the impact of foreshock turbulence can potentially contribute to dayside loss of planetary plasmas.

Abstract
Background and study aims Detecting colorectal neoplasia is the goal of high-quality screening and surveillance colonoscopy, as reflected by high adenoma detection rate (ADR) and adenomas per colonoscopy (APC). The aim of our study was to evaluate the performance of a novel artificial intelligence (AI)-aided polyp detection device, Skout, with the primary endpoints of ADR and APC in routine colonoscopy. Patients and methods We compared ADR and APC in a cohort of outpatients undergoing routine high-resolution colonoscopy with and without the use of a real-time, AI-aided polyp detection device. Patients undergoing colonoscopy with Skout were enrolled in a single-arm, unblinded, prospective trial and the results were compared with a historical cohort. All resected polyps were examined histologically. Results Eighty-three patients undergoing screening and surveillance colonoscopy at an outpatient endoscopy center were enrolled and outcomes compared with 283 historical control patients. Overall, ADR with and without Skout was 54.2 % and 40.6 % respectively ( P = 0.028) and 53.6 % and 30.8 %, respectively, in screening exams ( P = 0.024). Overall, APC rate with and without Skout was 1.46 and 1.01, respectively, ( P = 0.104) and 1.18 and 0.50, respectively, in screening exams ( P = 0.002). Overall, true histology rate (THR) with and without Skout was 73.8 % and 78.4 %, respectively, ( P = 0.463) and 75.0 % and 71.0 %, respectively, in screening exams ( P = 0.731). Conclusion We have demonstrated that our novel AI-aided polyp detection device increased the ADR in a cohort of patients undergoing screening and surveillance colonoscopy without a significant concomitant increase in hyperplastic polyp resection. AI-aided colonoscopy has the potential for improving the outcomes of patients undergoing colonoscopy.

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
BACKGROUND AND AIM Risk stratification is recommended in all patients with acute variceal bleeding (AVB). It remains unclear whether liver disease severity or upper gastrointestinal bleeding (UGIB) scoring algorithms offer superior predictive ability. We aimed to validate the AIMS65 score as a predictor of mortality in AVB, and to compare AIMS65 with established UGIB and liver disease severity risk stratification scores. METHODS International Classification of Diseases, Tenth Revision codes identified patients presenting with AVB to three tertiary centers over a 48-month period. Patients were risk-stratified using AIMS65, Rockall, pre-endoscopy Rockall, Child-Pugh, Model for End-stage Liver Disease (MELD) and United Kingdom MELD (UKELD) scores. Primary outcomes were inpatient and 6-week mortality and inpatient rebleeding. RESULTS Two hundred and twenty-three patients were included. Inpatient and 6-week mortality were 13.9% and 15.5% respectively. Prediction of inpatient mortality by AIMS65 (area under the receiver-operating characteristic curve [AUROC: 0.84]) was equivalent to UGIB (Rockall: 0.79, pre-Rockall: 0.78) and liver risk scores (MELD: 0.81, UKELD: 0.79, Child-Pugh: 0.78). AIMS65 score ≥3 best defined high- and low-risk groups for inpatient mortality (mortality 37.7% vs 4.9%). AIMS65 (AUROC: 0.62) was equivalent to UGIB risk scores (pre-Rockall: 0.64, Rockall: 0.70) in predicting inpatient rebleeding and superior to liver risk scores (MELD: 0.56, UKELD: 0.57, Child-Pugh: 0.60). CONCLUSIONS AIMS65 is equivalent to established UGIB and liver disease severity risk stratification scores in predicting mortality, and superior to liver scores in predicting rebleeding.

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.
