Abstract
During the early years of the COVID-19 pandemic, preclinical and clinical research were sped up and scaled up in both the public and private sectors and in partnerships between them. This resulted in some extraordinary advances, but it also raised a range of issues regarding the ethics, rigour, and integrity of scientific research, academic publication, and public communication. Many of the failures of scientific rigour and integrity that occurred during the pandemic were exacerbated by the rush to generate, disseminate, and implement research findings, which not only created opportunities for unscrupulous actors but also compromised the methodological, peer review, and advisory processes that would usually identify sub-standard research and prevent compromised clinical or policy-level decisions. While it would be tempting to attribute these failures of science and its translation solely to the "unprecedented" circumstances of the COVID-19 pandemic, the reality is that they preceded the pandemic and will continue to arise once it is over. Existing strategies for promoting scientific rigour and integrity need to be made more rigorous, better integrated into research training and institutional cultures, and made more sophisticated. They might also need to be modified or supplemented with other strategies that are fit for purpose not only in public health emergencies but in any research that is sped-up and scaled up to address urgent unmet medical needs.

Abstract
Obsessive-compulsive disorder (OCD) affects 2-3% of the population. One-third of patients are poorly responsive to conventional therapies, and for a subgroup, gamma knife capsulotomy (GKC) is an option. We examined lesion characteristics in patients previously treated with GKC through well-established programs in Providence, RI (Butler Hospital/Rhode Island Hospital/Alpert Medical School of Brown University) and São Paulo, Brazil (University of São Paolo). Lesions were traced on T1 images from 26 patients who had received GKC targeting the ventral half of the anterior limb of the internal capsule (ALIC), and the masks were transformed into MNI space. Voxel-wise lesion-symptom mapping was performed to assess the influence of lesion location on Y-BOCS ratings. General linear models were built to compare the relationship between lesion size/location along different axes of the ALIC and above or below-average change in Y-BOCS ratings. Sixty-nine percent of this sample were full responders (≥35% improvement in OCD). Lesion occurrence anywhere within the targeted region was associated with clinical improvement, but modeling results demonstrated that lesions occurring posteriorly (closer to the anterior commissure) and dorsally (closer to the mid-ALIC) were associated with the greatest Y-BOCS reduction. No association was found between Y-BOCS reduction and overall lesion volume. GKC remains an effective treatment for refractory OCD. Our data suggest that continuing to target the bottom half of the ALIC in the coronal plane is likely to provide the dorsal-ventral height required to achieve optimal outcomes, as it will cover the white matter pathways relevant to change. Further analysis of individual variability will be essential for improving targeting and clinical outcomes, and potentially further reducing the lesion size necessary for beneficial outcomes.

Abstract
Ice streams flowing into Ross Ice Shelf are presently responsible for around 10% of the mass flux from West Antarctica, with the noteworthy exception of Kamb Ice Stream, which stagnated in the late 1800s. The subsequent reduction in ice supply led to grounding-line retreat at the coastal margin where Kamb transitions into the floating Ross Ice Shelf. Grounding-line migration is linked to broader changes in ice-sheet mass balance and sea level, but our understanding of related ice, ocean and seafloor interactions is limited by the difficulty in accessing these remote regions. Here we report in situ observations from an underwater vehicle deployed at Kamb that show how fine-scale variability in ice and ocean structure combine to influence a diversity of ice-ocean interactions. We found a stratified water column within a tenth of a degree of freezing at the ice base and mapped basal crevasses with supercooled water and active marine ice formation. At the seafloor, we interpret parallel ridges as crevasse impressions left as the ice lifted off during grounding-line retreat. These observations from a recently ungrounded sub-shelf environment illuminate both the geomorphological signatures of past grounding-line retreat and the fine-scale sensitivity of ongoing ice-ocean interactions to ice topography.

Abstract
BACKGROUND Primary central nervous system lymphoma (PCNSL) is a rare and distinct entity within diffuse large B-cell lymphoma presenting with variable response rates probably to underlying molecular heterogeneity. PATIENTS AND METHODS To identify and characterize PCNSL heterogeneity and facilitate clinical translation, we carried out a comprehensive multi-omic analysis [whole-exome sequencing, RNA sequencing (RNA-seq), methylation sequencing, and clinical features] in a discovery cohort of 147 fresh-frozen (FF) immunocompetent PCNSLs and a validation cohort of formalin-fixed, paraffin-embedded (FFPE) 93 PCNSLs with RNA-seq and clinico-radiological data. RESULTS Consensus clustering of multi-omic data uncovered concordant classification of four robust, non-overlapping, prognostically significant clusters (CS). The CS1 and CS2 groups presented an immune-cold hypermethylated profile but a distinct clinical behavior. The 'immune-hot' CS4 group, enriched with mutations increasing the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) and nuclear factor-κB activity, had the most favorable clinical outcome, while the heterogeneous-immune CS3 group had the worse prognosis probably due to its association with meningeal infiltration and enriched HIST1H1E mutations. CS1 was characterized by high Polycomb repressive complex 2 activity and CDKN2A/B loss leading to higher proliferation activity. Integrated analysis on proposed targets suggests potential use of immune checkpoint inhibitors/JAK1 inhibitors for CS4, cyclin D-Cdk4,6 plus phosphoinositide 3-kinase (PI3K) inhibitors for CS1, lenalidomide/demethylating drugs for CS2, and enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) inhibitors for CS3. We developed an algorithm to identify the PCNSL subtypes using RNA-seq data from either FFPE or FF tissue. CONCLUSIONS The integration of genome-wide data from multi-omic data revealed four molecular patterns in PCNSL with a distinctive prognostic impact that provides a basis for future clinical stratification and subtype-based targeted interventions.

Abstract
Plasma circulating tumour DNA (ctDNA) has been suggested to be a viable biomarker of response to treatment in patients with high grade serous ovarian carcinoma (HGSOC). TP53 mutations are present in more than 90% of HGSOCs but somatic variants are distributed across all exonic regions of the gene, requiring next generation sequencing (NGS) technologies for mutational analysis. In this study, we compared the suitability of the Accel (Swift) and Oncomine (ThermoFisher) panels for identification of TP53 mutations in ctDNA of HGSOC patients (N = 10). Only 6 patients (60%) were found to have TP53 mutations using the ACCEL panel but the addition of molecular tags in the Oncomine panel improved ctDNA detection with at least one mutation detected in all cases (100%). Orthogonal validation of the 14 somatic variants found by Oncomine, using droplet digital PCR, confirmed 79% (11/14) of the identified mutations. Overall, the Oncomine panel with unique molecular identifiers (UMI) appears more useful for ctDNA analysis in HGSOC.

Abstract
Organizations are increasingly committing to biodiversity protection targets with focus on 'nature-positive' outcomes, yet examples of how to feasibly achieve these targets are needed. Here we propose an approach to achieve nature-positive targets with respect to the embodied biodiversity impacts of an organization's food consumption. We quantify these impacts using a comprehensive database of life-cycle environmental impacts from food, and map exploratory strategies to meet defined targets structured according to a mitigation and conservation hierarchy. By considering the varying needs and values across the organization's internal community, we identify a range of targeted approaches towards mitigating impacts, which balance top-down and bottom-up actions to different degrees. Delivering ambitious nature-positive targets within current constraints will be challenging, particularly given the need to mitigate cumulative impacts. Our results evidence that however committed an organization is to being nature positive in its food provision, this is unachievable in the absence of systems change.

Abstract
BACKGROUND Income and housing are pervasive social determinants of health. Subsidized housing is a prominent affordability mechanism in Canada; however, waitlists are lengthy. Subsidized rents should provide greater access to residual income, which may theoretically improve health outcomes. However, little is known about the health of tenants who wait for and receive subsidized housing. This is especially problematic for New Brunswick, a Canadian province with low population density, whose inhabitants experience income inequality, social exclusion, and challenges with healthcare access. METHODS: This study will use a longitudinal, prospective matched cohort design. All 4,750 households on New Brunswick's subsidized housing wait list will be approached to participate. The survey measures various demographic, social and health indicators at six-month intervals for up to 18 months as they wait for subsidized housing. Those who receive housing will join an intervention group and receive surveys for an additional 18 months post-move date. With consent, participants will have their data linked to a provincial administrative database of medical records. DISCUSSION: Knowledge of housing and health is sparse in Canada. This study will provide stakeholders with a wealth of health information on a population that is historically under-researched and underserved.

Abstract
Infection at the surgical site for dental implants results in failed procedures, patient pain, burdensome economic impact, and the over-prescription of prophylactic antibiotics. Mesoporous silica films as coatings for implants may provide an ideal antimicrobial drug storage and local release vector to the site of infection, however traditional drug loading techniques result in insufficient drug load and short-term release kinetics. In this work, we have applied a method to use a surfactant-antimicrobial drug octenidine dihydrochloride (OCT) as a template for mesostructured silica, to demonstrate silica-OCT composite films. The films are synthesized by evaporation induced self-assembly (EISA) and we explore the effects of synthesis parameters on porous film structure, OCT incorporation, and OCT drug release rates. Drug micelle incorporation into the silica mesostructure was highly dependent on silica precursor pre-reaction to form silica oligomers before film spin-casting. The OCT drug concentration of the synthesis solution dictated the time required for effective incorporation (without phase separation), with total loading in the film of up to 90% by mass. The OCT content in the films was found to directly determine the timescale of drug release, from 2 to 8 h for a single layer film. The total release timescale was increased by the addition of multiple layers of OCT-silica films to nearly 2 weeks. Drug release from films completely inhibited Streptococcus mutans (UA159) growth, while drug-free porous silica films showed no increase in bacterial growth over non-porous control. These OCT-silica films have a significant potential to store and release antimicrobial drugs from dental implant surfaces.

Abstract
Accurate modeling of the heart electrophysiology to predict arrhythmia susceptibility remains a challenge. Current electrophysiological analyses are hypothesis-driven models drawing conclusions from changes in a small subset of electrophysiological parameters because of the difficulty of handling and understanding large datasets. Thus, we develop a framework to train machine learning classifiers to distinguish between healthy and arrhythmic cardiomyocytes using their calcium cycling properties. By training machine learning classifiers on a generated dataset containing a total of 3,003 healthy derived cardiomyocytes and their various arrhythmic states, the multi-class models achieved >90% accuracy in predicting arrhythmia presence and type. We also demonstrate that a binary classifier trained to distinguish cardiotoxic arrhythmia from healthy electrophysiology could determine the key biological changes associated with that specific arrhythmia. Therefore, machine learning algorithms can be used to characterize underlying arrhythmic patterns in samples to improve in vitro preclinical models and complement current in vivo systems. Calcium reporter enabled analysis of hPSC-derived CM electrophysiology Calcium electrophysiology can be decomposed to train machine learning classifiers Multi-class classifier distinguishes different forms of arrhythmias Binary-class classifiers identify key electrophysiological changes a priori

Abstract
Introduction
Major Depressive Disorder (MDD) is prevalent, often chronic, and requires ongoing monitoring of symptoms to track response to treatment and identify early indicators of relapse. Remote Measurement Technologies (RMT) provide an exciting opportunity to transform the measurement and management of MDD, via data collected from inbuilt smartphone sensors and wearable devices alongside app-based questionnaires and tasks.
Objectives
To describe the amount of data collected during a multimodal longitudinal RMT study, in an MDD population.
Methods
RADAR-MDD is a multi-centre, prospective observational cohort study. People with a history of MDD were provided with a wrist-worn wearable, and several apps designed to: a) collect data from smartphone sensors; and b) deliver questionnaires, speech tasks and cognitive assessments and followed-up for a maximum of 2 years.
Results
A total of 623 individuals with a history of MDD were enrolled in the study with 80% completion rates for primary outcome assessments across all timepoints. 79.8% of people participated for the maximum amount of time available and 20.2% withdrew prematurely. Data availability across all RMT data types varied depending on the source of data and the participant-burden for each data type. We found no evidence of an association between the severity of depression symptoms at baseline and the availability of data. 110 participants had > 50% data available across all data types, and thus able to contribute to multiparametric analyses.
Conclusions
RADAR-MDD is the largest multimodal RMT study in the field of mental health. Here, we have shown that collecting RMT data from a clinical population is feasible.
Disclosure
No significant relationships.

Abstract
OBJECTIVES The aim of this study was to test the feasibility and effectiveness of two models (face-to-face vs online teaching) of clinically integrating evidence-based medicine (EBM) teaching in an undergraduate medical school. DESIGN AND SETTING A pilot study of face-to-face versus online EBM teaching. PARTICIPANTS This study focused on undergraduate medical students who entered the University of Buckingham Medical School MBChB course in 2016 (n=65). Of the 65 students, 45 received face-to-face teaching, while 20 received online teaching. MAIN OUTCOME MEASURES Feasibility was assessed by the ability to deliver the content, students' engagement during teaching and their completion rates in formative assessments-Assessing Competency in EBM (ACE) tool, and educational prescriptions (EPs). Effectiveness of teaching for the two models was compared by evaluating students' performance in the formative assessments and in the summative final professional examination and final year EBM objective structured clinical examination (OSCE). RESULTS We had similar students' engagement and completion rates in formative assessments in both models. Students receiving face-to-face teaching performed better in EPs (mean difference=-2.28, 95% CI: -4.31 to -0.26). There was no significant difference in performances in the ACE tool (mean difference=-1.02, 95% CI: -2.20 to 0.16); the written final professional exams (mean difference=-0.11, 95% CI: -0.65 to 0.44) and the EBM OSCE station (mean difference=-0.81, 95% CI: -2.38 to 0.74). CONCLUSIONS It was feasible to deliver both models of clinically integrated EBM teaching. While students in the face-to-face model scored higher in EPs; there was no significant difference between the two models of teaching as measured by performances in the ACE tool or the summative assessments.

Abstract
In May 2020, the Coalition for Physician Accountability's Work Group on Medical Students in the Class of 2021 Moving Across Institutions for Post Graduate Training (WG) released its final report and recommendations. These recommendations pertain to away rotations, virtual interviews, Electronic Residency Application Service opening for programs and the overall residency timeline, and general communications and attempt to provide clarity and level the playing field during the 2020-2021 residency application cycle. The WG's aims include promoting professional accountability by improving the quality, efficiency, and continuity of the education, training, and assessment of physicians. The authors argue the first 3 WG recommendations may disproportionately impact candidates from historically excluded and underrepresented groups in medicine (HEURGMs) and may affect an institution's ability to ensure equity in the selection of residency applicants and, thus, warrant further consideration. The authors examine these recommendations from a diversity, equity, and inclusion (DEI) perspective. For each of the first 3 WG recommendations, the authors highlight new opportunities created by the recommendations and detail challenges that programs must carefully navigate to ensure equity for all candidates. The authors also recommend solutions to guide programs as they address these challenges, meet new common program requirements, and attempt to promote equity for HEURGMs. Finally, the authors recommend that after the 2020-2021 recruitment cycle, the medical education community evaluate DEI-related outcomes of both the WG's and the authors' recommendations and incorporate the findings into future application cycles.

Abstract
Abstract
Aim
To determine if ketamine sedation is a safe and cost-effective way of treating paediatric patients presenting with minor injuries, requiring plastic surgery procedures, in the emergency department.
Method
A retrospective cohort study was carried out over a 9-month period in children between ages 18 months and 16 years old, presenting to the paediatric emergency department at Chelsea and Westminster Hospital with minor injuries requiring plastic surgery input. The data collected included previously validated co-primary outcome measures of surgical site infection at 7 days and cosmetic appearance summary score at a minimum of 4 months. Parental satisfaction surveys were completed at 4 months to assess perceived quality of treatment. A cost analysis comparison against procedures completed under general anaesthetic was also undertaken.
Results
During the 9-month period of study, 24 minor procedures were performed under ketamine in the paediatric emergency department. There were no serious adverse events recorded. Three cases exceeded the recommended 20-minute maximum procedure duration, but there was no associated adverse outcome. No cases required further procedures under general anaesthesia and there were no cases of surgical site infections at 7 days. Parents reported extremely favourable outcomes using this technique, with an average overall satisfaction score of 9.2 (assessed over a number of parameters, where 10 is complete satisfaction).
Conclusions
Ketamine procedural sedation in the paediatric population is a safe and cost-effective method for the treatment of minor plastic surgery procedures, with low risk for surgical site infection post-operatively, and high parent satisfaction rates

Abstract
PURPOSE Neurocognitive difficulties and early childhood speech/motor delays are well documented amongst older adolescents and young adults considered at risk for psychosis-spectrum diagnoses. We aimed to test associations between unusual or psychotic-like experiences (PLEs), co-occurring distress/emotional symptoms, current cognitive functioning and developmental delays/difficulties in young people (aged 8-18 years) referred to Child and Adolescent Mental Health Services in South London, UK. METHODS Study 1 examined receptive language, verbal learning and caregiver-reported speech and motor delays/difficulties in a sample of 101 clinically-referred children aged 8-14 years, comparing those reporting no PLEs (n = 19), PLEs without distress (n = 16), and PLEs with distress (n = 66). Study 2 tested associations of severity of distressing PLEs with vocabulary, perceptual reasoning, word reading and developmental delays/difficulties in a second sample of 122 adolescents aged 12-18 years with distressing PLEs. RESULTS In Study 1, children with distressing PLEs had lower receptive language and delayed recall and higher rates of developmental delays/difficulties than the no-PLE and non-distressing PLE groups (F values: 2.3-2.8; p values: < 0.005). Receptive language (β = 0.24, p = 0.03) and delayed recall (β = - 0.17, p = 0.02) predicted PLE distress severity. In Study 2, the cognitive-developmental variables did not significantly predict PLE distress severity (β values = 0.01-0.22, p values: > 0.05). CONCLUSION Findings may be consistent with a cognitive-developmental model relating distressing PLEs in youth with difficulties in cognitive functioning. This highlights the potential utility of adjunctive cognitive strategies which target mechanisms associated with PLE distress. These could be included in cognitive-behavioural interventions offered prior to the development of an at-risk mental state in mental health, educational or public health settings.

Abstract
Abstract
Aim
Treatment of skin and soft tissue abscesses forms a substantial part of the emergency general surgery workload. Abscesses account for approximately 2% of presentations to Accident and Emergency, with 0.9% of patients requiring surgical intervention. Incision and drainage is often performed in theatre and may necessitate admission to hospital, impacting bed space and theatre availability. This study aims to identify if the introduction of a clinic-based abscess service could reduce the number of abscess drainages in theatre without compromise to clinical outcomes.
Method
Retrospective data was collected for patients undergoing abscess treatment at Musgrove Park Hospital (Taunton) in September 2019. Subsequently, a Nurse-led abscess drainage pathway was initiated in Emergency Surgery Ambulatory Clinic (ESAC) encompassing initial assessment and drainage at the bedside. Prospective data was then collected for abscesses drained in theatre and ESAC during September 2020 and compared with data from 2019.
Result
22 abscess drainages were performed in September 2019 vs 25 in September 2020. 8 cases were carried out in theatre during September 2020, with the rest being treated in ESAC. Of those who were treated in clinic (n = 17), admission was prevented in 16 patients. Readmission rates were similar between ESAC (16%) and theatre (18.1%).
Conclusions
A clinic-based abscess service is achievable and prevents unnecessary use of theatres and hospital admissions, with comparable re-presentation rates. A nurse led approach also relieves pressure on Doctors during busy surgical on calls. Nonetheless, a larger data set would be needed to consolidate the findings from this study.

Abstract
Introduction The emergence of the coronavirus pandemic and subsequent UK lockdown resulted in a significant reduction in elective vascular surgery to increase critical care capacity. We aimed to ascertain the impact of lockdown on the workload of a busy vascular surgical unit. Method Data on all major vascular procedures performed between March 2020 and June 2020 were collected prospectively. Comparison to the same time period over the last 6 years was performed using a prospectively maintained database. Results 92 major cases were performed, a reduction of 30% compared with cases performed during similar periods (803 cases total, mean 133), with an increased proportion of unplanned & emergency cases(35.9% & 31.5% vs 31.4% & 20.5%). There was a significant reduction in aortic procedures (19 vs mean 36). Despite the reduction in cases there was a similar number of amputations performed (9 vs mean 10). Conclusions The lockdown period resulted in a 30% reduction in cases performed with far fewer aortic procedure performed and a similar number of amputations. These pending cases will need consideration, especially with critical care capacity to ensure they are completed within a timely period. Considerations for capacity are also pertinent given the approach of winter and the possibility of a second wave.

Abstract
BACKGROUND Medical students often struggle to understand the relevance of Evidence Based Medicine (EBM) to their clinical practice, yet it is a competence that all students must develop prior to graduation. Objective structured clinical examinations (OSCEs) are a valued assessment tool to assess critical components of EBM competency, particularly different levels of mastery as they progress through the course. This study developed and evaluated EBM based OSCE stations with an aim to establish a spiral approach for EBM OSCE stations for undergraduate medical students. METHODS OSCE stations were developed with increasingly complex EBM tasks. OSCE stations were classified according to the classification rubric for EBP assessment tools (CREATE) framework and mapped against the recently published core competencies for evidence-based practice (EBP). Performance data evaluation was undertaken using Classical Test Theory analysing mean scores, pass rates, and station item total correlation (ITC) using SPSS. RESULTS Six EBM based OSCE stations assessing various stages of EBM were created for use in high stakes summative OSCEs for different year groups across the undergraduate medical degree. All OSCE stations, except for one, had excellent correlation coefficients and hence a high reliability, ranging from 0.21-0.49. The domain mean score ranged from 13.33 to 16.83 out of 20. High reliability was demonstrated for the each of the summative OSCE circuits (Cronbach's alpha = 0.67-0.85). In the CREATE framework these stations assessed knowledge, skills, and behaviour of medical students in asking, searching, appraising, and integrating evidence in practice. The OSCE stations were useful in assessing six core evidence-based practice competencies, which are meant to be practiced with exercises. A spiral model of OSCEs of increasing complexity was proposed to assess EBM competency as students progressed through the MBChB course. CONCLUSIONS The use of the OSCEs is a feasible method of authentically assessing leaner EBM performance and behaviour in a high stakes assessment setting. Use of valid and reliable EBM-based OSCE stations provide evidence for continued development of a hierarchy of assessing scaffolded learning and mastery of EBM competency. Further work is needed to assess their predictive validity.

Abstract
Purpose: We present the clinico-radiological findings of neuroendocrine tumour metastases to the orbit.Methods: This was a multicentre, retrospective study of patients with neuroendocrine tumour metastases to the orbit. Data was collected from medical records across five different sites within Australia and the United Kingdom.Results: Nine patients (eleven lesions) were identified. The most common presenting complaint was diplopia (5/9, 56%). Disease occurred bilaterally in two patients. Seven patients (78%) had extraocular muscle involvement. The lateral recti (4/9, 44%) and superior recti (2/9, 22%) were the most commonly affected. Ocular presentation preceded primary tumour diagnosis in three patients (33%). On orbital imaging, metastases were most commonly reported as well circumscribed, ovoid or round, heterogeneous, contrast-enhancing masses. Features of intralesional haemorrhage and bony invasion are uncommonly reported.Conclusions: Neuroendocrine tumour metastasis to the orbit is uncommon. Metastases have a propensity for the extraocular muscles, commonly presenting as heterogeneous, well circumscribed, contrast-enhancing lesions on neuroimaging. New ocular symptoms, a history of neuroendocrine tumours, and these radiological findings, should lead to high clinical suspicion of metastatic disease. Atypical findings warrant biopsy to exclude other causes of orbital lesions.

Abstract
Objective: Matters of sexuality and sexual health are common in the practice of child and adolescent psychiatry (CAP), yet clinicians can feel ill-equipped to address them with confidence. To address this gap in training and practice, we developed, implemented, and evaluated an educational module enhanced by videotaped depictions of expert clinicians interacting with professional actors performing as standardized patients (SPs). Methods: We developed an educational resource highlighting common issues of sexual health relevant to CAP practice, including sexual development, psychotropic-related side effects, and sexuality in children with autism. We wrote original scripts, based on which two clinicians interacted with three SPs. Digital recordings were edited to yield 5 clips with a cumulative running time of 20 min. The clips were interspersed during a 90-min session comprising didactic and interactive components. Due to the COVID-19 pandemic, we used synchronous videoconferencing, which allowed content dissemination to several training programs across the country. Results: We recruited 125 learners from 16 CAP training programs through the American Academy of CAP's Alliance for Learning and Innovation (AALI). Routine inquiry into adolescent patients' sexual function was uncommon, reported by only 28% of participants, with "awkward" and "uncomfortable" the most common terms mentioned in reference to the clinical task. The didactic intervention led to measurable improvements after 2 weeks in skills and knowledge (p = 0.004) and in attitudes (p < 0.001). The three items with the greatest improvement were: (a) availability of developmentally tailored resources; (b) comfort in addressing sexual development with underage patients; and (c) with parents or guardians of neuroatypical or developmentally disabled patients (p < 0.001 for each). Conclusions: A sexual health curriculum enriched by video-based examples can lead to measurable improvement in outcomes pertinent to the clinical practice of CAP. These educational materials are available for distribution, use and adaptation by local instructors. Our study also provides proof-of-principle for the use of multisite educational initiatives in CAP through synchronized videoconferencing.

Abstract
Oncogenic fusions involving neurotrophic receptor tyrosine kinase (NTRK) genes are being increasingly identified in a range of mesenchymal tumours unrelated to infantile fibrosarcoma or cellular congenital mesoblastic nephroma, where the canonical ETV6-NTRK3 fusion was first described more than two decades ago. Recognition of these NTRK-rearranged tumours poses a diagnostic challenge to surgical pathologists due to their non-specific clinical and pathological features. However, their recognition is of heightened importance, particularly in locally advanced and metastatic sarcomas, due to the recent availability of selective and highly effective targeted therapy. Herein, we present an Australian multi-institutional series of six of these rare NTRK-rearranged mesenchymal neoplasms to share the local experience and diagnostic challenges as well as to highlight key morphological patterns and immunoprofiles that provide the most helpful clues in routine practice. We also propose a diagnostic algorithm for the detection of these fusions, drawing attention to the limitations of ancillary studies including immunohistochemistry against tropomyosin receptor kinase (TRK) protein, fluorescence in situ hybridisation (FISH) and next generation sequencing.

Abstract
The outcome of 110 patients with paediatric onset mucopolysaccharidosis II (MPS II) since the commercial introduction of enzyme replacement therapy (ERT) in England in 2007 is reported. Median length of follow up was 10 years 3 months (range = 1 y 2 m to 18 years 6 month). 78 patients were treated with ERT, 18 had no ERT or disease modifying treatment 7 had haematopoietic stem cell transplant, 4 experimental intrathecal therapy and 3 were lost to follow up. There is clear evidence of improved survival (median age of death of ERT treated (n = 16) = 15.13 years (range = 9.53 to 20.58 y), and untreated (n = 17) = 11.43 y (0.5 to 19.13 y) p = .0005). Early introduction of ERT improved respiratory outcome at 16 years, the median FVC (% predicted) of those in whom ERT initiated <8 years = 69% (range = 34-86%) and 48% (25-108) (p = .045) in those started >8 years. However, ERT appears to have minimal impact on hearing, carpal tunnel syndrome or progression of cardiac valvular disease. Cardiac valvular disease occurred in 18/46 (40%), with progression occurring most frequently in the aortic valve 13/46 (28%). The lack of requirement for neurosurgical intervention in the first 8 years of life suggests that targeted imaging based on clinical symptomology would be safe in this age group after baseline assessments. There is also emerging evidence that the neurological phenotype is more nuanced than the previously recognized dichotomy of severe and attenuated phenotypes in patients presenting in early childhood.

Abstract
Primary ovarian mucinous tumors can be difficult to distinguish from metastatic gastrointestinal neoplasms by histology alone. The expected immunoprofile of a suspected metastatic lower gastrointestinal tumor is CK7-/CK20+/CDX2+/PAX8-. This study assesses the addition of a novel marker SATB2, to improve the diagnostic algorithm. A test cohort included 155 ovarian mucinous tumors (105 carcinomas and 50 borderline tumors) and 230 primary lower gastrointestinal neoplasms (123 colorectal adenocarcinomas and 107 appendiceal neoplasms). All cases were assessed for SATB2, PAX8 CK7, CK20, and CDX2 expression on tissue microarrays. Expression was scored in a 3-tier system as absent, focal (1-50% of tumor cells) and diffuse ( >50% of tumor cells) and then categorized into either absent/present or nondiffuse/diffuse. SATB2 and PAX8 expression was further evaluated in ovarian tumors from an international cohort of 2876 patients (expansion cohort, including 159 mucinous carcinomas and 46 borderline mucinous tumors). The highest accuracy of an individual marker in distinguishing lower gastrointestinal from ovarian mucinous tumors was CK7 (91.7%, nondiffuse/diffuse cut-off) followed by SATB2 (88.8%, present/absent cut-off). The most effective combination was CK7 and SATB2 with accuracy of 95.3% using the 3-tier interpretation, absent/focal/diffuse. This combination outperformed the standard clinical set of CK7, CK20 and CDX2 (87.5%). Re-evaluation of outlier cases confirmed ovarian origin for all but one case. The accuracy of SATB2 was confirmed in the expansion cohort (91.5%). SATB2 expression was also detected in 15% of ovarian endometrioid carcinoma but less than 5% of other ovarian histotypes. A simple two marker combination of CK7 and SATB2 can distinguish lower gastrointestinal from ovarian primary mucinous tumors with greater than 95% accuracy. PAX8 and CDX2 have value as second-line markers. The utility of CK20 in this setting is low and this warrants replacement of this marker with SATB2 in clinical practice.

Abstract
OBJECTIVE To compare the germline BRCA1 and BRCA2 mutation (gBRCA) status in women with high-grade serous tubo-ovarian and primary peritoneal carcinoma with and without serous tubal intra-epithelial carcinomas (serous tubal intra-epithelial carcinoma-positive vs serous tubal intra-epithelial carcinoma-negative). MATERIALS AND METHODS A retrospective study was performed of patients in Western Australia diagnosed with high-grade serous tubo-ovarian and primary peritoneal carcinoma and referred for genetic counseling and gBRCA testing from July 1, 2014 to June 30, 2017. Histopathology reports were reviewed to ascertain whether serous tubal intra-epithelial carcinoma was present. Personal or family gBRCA status, family history, age at diagnosis, mode of treatment (neoadjuvant chemotherapy vs primary surgery), and stage were also recorded. RESULTS A total of 269 women with high-grade serous tubo-ovarian and primary peritoneal carcinoma were referred for genetic counseling and testing. 114 patients were excluded because the serous tubal intra-epithelial carcinoma status was not assessable or because patients did not attend for genetic assessment. 155 patients (55 serous tubal intra-epithelial carcinoma-positive and 100 serous tubal intra-epithelial carcinoma-negative) underwent genetic testing. gBRCA mutations were found in 27.8% of serous tubal intra-epithelial carcinoma-positive patients compared with 14.0% of serous tubal intra-epithelial carcinoma-negative patients (p=0.094). Of those found to have a gBRCA mutation, 89.7% reported a positive personal or family history of BRCA-related cancers. CONCLUSIONS The gBRCA mutation detection rate in serous tubal intra-epithelial carcinoma-positive patients was nearly double that of serous tubal intra-epithelial carcinoma-negative patients. Factors such as a positive family history of BRCA-related cancers were seen at a higher proportion in the mutation positive women.

Abstract
BACKGROUND We aimed to explore the existing use of pain assessment tools and guidelines, and develop understanding of the practical considerations required to facilitate their use within the nursing home, hospital and community settings. METHODS A self-administered web-based survey was conducted with nurses, health and social care workers with an interest in the assessment of pain in older adults with cognitive impairment. The survey was distributed to participants in Austria, Belgium, Denmark, Germany, The Netherlands, Switzerland and United Kingdom. RESULTS Only a minority of staff reported use of (inter-)national or local standards or specific pain assessment tools in daily practice. A range of tools were reported as being used, which varied across country. While participants generally reported that these pain assessment tools were easy/very easy to use, many participants reported that they were difficult to interpret. Assessment is generally performed whilst providing nursing care. This was highlighted in 70-80% of all participating countries. While many of these tools rely on facial expression of pain, facial expressions were considered to be the least useful in comparison to other items. Furthermore findings showed that nurses employed in long-term care settings did not feel that they were educated enough in pain assessment and management. CONCLUSION Our findings suggest that pain education is required across all countries surveyed. This should include a focus on guidelines and standards for assessment and subsequent management of pain. Findings suggest that clinical staff find interpreting facial expressions in relation to pain more difficult.

Abstract
The development of the law of consent has led to much discussion within the dental literature as to how these changes might impact practice. The move from a practitioner-focused standard of consent to a patient-focused standard has altered the nature of the framework required to support a patient's decision-making to avoid an allegation or finding of a negligent consent process. Contrastingly, there has been little in the way of exploration as to how the law of battery (in civil matters) and assault (in criminal cases), where consent is entirely absent, might apply to dentistry and the practice of the profession. This article considers the law of consent, using several key examples from dentistry, as well as providing an update of recent case law of relevance to dental practice.

Abstract
BACKGROUND/OBJECTIVES The iron-binding affinity of vaginal lactoferrin (Lf) reduces iron available to genital pathogens. We describe host reproductive, nutritional, infection and iron biomarker profiles affecting vaginal Lf concentration in young nulliparous and primigravid women in Burkina Faso. SUBJECTS/METHODS Vaginal eluates from women who had participated in a randomized, controlled periconceptional iron supplementation trial were used to measure Lf using a competitive double-sandwich ELISA. For this analysis samples from both trial arms were combined and pregnant and non-pregnant cohorts compared. Following randomization Lf was measured after 18 months (end assessment) for women remaining non-pregnant, and at two antenatal visits for those becoming pregnant. Associations between log Lf levels and demographic, anthropometric, infection and iron biomarker variables were assessed using linear mixed models. RESULTS Lf samples were available for 712 non-pregnant women at end assessment and for 303 women seen at an antenatal visit. Lf concentrations of pregnant women were comparable to those of non-pregnant, sexually active women. Lf concentration increased with mid-upper-arm circumference, (P = 0.047), body mass index (P = 0.018), Trichomonas vaginalis (P < 0.001) infection, bacterial vaginosis (P < 0.001), serum C-reactive protein (P = 0.048) and microbiota community state types III/IV. Adjusted Lf concentration was positively associated with serum hepcidin (P = 0.047), serum ferritin (P = 0.018) and total body iron stores (P = 0.042). There was evidence that some women maintained persistently high or low Lf concentrations from before, and through, pregnancy. CONCLUSION Lf concentrations increased with genital infection, higher BMI, MUAC, body iron stores and hepcidin, suggesting nutritional and iron status influence homeostatic mechanisms controlling vaginal Lf responses.

Abstract
In traditional medical practice, the diagnostic interview is focused on symptom collection, diagnosis, and treatment. The psychiatric interview is based on the medical model, but mental health clinicians lack the tests found in general medicine. Rapport is the most essential tool for the psychiatrist to uncover symptoms and develop a diagnosis and treatment plan. This article brings a scientific lens to the psychiatric interview. Under this microscope the value of eliciting the patient's well-being at the outset of the interview becomes clear. Using positive psychology, an evidenced-based rationale for the positive assessment is outlined and methodology and practice of the assessment reviewed.

Abstract
Background We have shown that the differentiation of human-induced pluripotent stem cells (hiPSCs) into endothelial cells (ECs) is more efficient when performed with a 3-dimensional (3D) scaffold of biomaterial than in monolayers. The current study aims to further increase hiPSC-EC differentiation efficiency by deciphering the signaling pathways in 3D scaffolds. Methods and results We modified our 3D protocol by using U-46619 to upregulate both p38 mitogen-activated protein kinase (p38MAPK) and extracellular signal-regulated kinase 1/2 (ERK1/2) signaling, which increased the differentiation efficiency (as measured by CD31 expression) to as high as 89% in two established hiPSC lines. The differentiated cells expressed arteriovenous, but not lymphatic, markers; formed tubular structures and EC lumen in vitro; had significantly shorter population-doubling times than monolayer-differentiated hiPSC-ECs; and restored perfusion and vascularity in a murine hind limb ischemia model. The differentiation efficiency was also > 85% in three hiPSC lines that had been derived from patients with diseases or disease symptoms that have been linked to endothelial dysfunction. Conclusions These observations demonstrate that activating both p38MAPK and ERK1/2 signaling pathways with U-46619 improves the efficiency of arteriovenous hiPSC-EC differentiation and produces cells with greater proliferative capacity.

Abstract
PURPOSE To develop entrustable professional activities (EPAs) for psychiatry and to demonstrate an innovative, validity-enhancing methodology that may be relevant to other specialties. METHOD A national task force employed a three-stage process from May 2014 to February 2017 to develop EPAs for psychiatry. In stage 1, the task force used an iterative consensus-driven process to construct proposed EPAs. Each included a title, full description, and relevant competencies. In stage 2, the task force interviewed four nonpsychiatric experts in EPAs and further revised the EPAs. In stage 3, the task force performed a Delphi study of national experts in psychiatric education and assessment. All survey participants completed a brief training program on EPAs. Quantitative and qualitative analysis led to further modifications. Essentialness was measured on a five-point scale. EPAs were included if the content validity index was at least 0.8 and the lower end of the asymmetric confidence interval was not lower than 4.0. RESULTS Stages 1 and 2 yielded 24 and 14 EPAs, respectively. In stage 3, 31 of the 39 invited experts participated in both rounds of the Delphi study. Round 1 reduced the proposed EPAs to 13. Ten EPAs met the inclusion criteria in Round 2. CONCLUSIONS The final EPAs provide a strong foundation for competency-based assessment in psychiatry. Methodological features such as critique by nonpsychiatry experts, a national Delphi study with frame-of-reference training, and stringent inclusion criteria strengthen the content validity of the findings and may serve as a model for future efforts in other specialties.

Abstract
Traumatic intrusion is a luxation type of injury where the tooth is displaced along the axis of the tooth, into the alveolus. This injury is regarded as serious because of the tissue damage that it causes. The traumatic movement is associated with severe damage to the periodontal ligament, pulpal tissue, root and alveolar socket. Despite its severity, the rare occurrence of this injury in permanent teeth has resulted in limited studies of immature and mature permanent incisors. The purpose of this paper is to review this luxation injury of permanent immature incisors, and to describe its diagnosis, treatment and management. In particular, we describe the repositioning strategies used in cases of intrusion injury. These include (i) monitoring spontaneous re-eruption, (ii) active orthodontic repositioning and (iii) surgical repositioning. Firstly, monitoring spontaneous re-eruption is observing and waiting for the intruded tooth to return to its original position. This process is not a normal developmental eruption and the outcome is not always predictable, nor is the time needed for this to happen. Secondly, active orthodontic repositioning is used to describe the process of rapidly moving the intruded tooth to its original position with the aid of an orthodontic appliance. Active orthodontic repositioning is often misunderstood as normal orthodontic movement. Orthodontic movement allows for periodontal ligament remodelling, using light intermittent forces. In contrast the active orthodontic repositioning used to move intruded incisors is rapid, and the primary aim is to achieve correct tooth position as rapidly as possible. Thirdly, surgical repositioning uses surgical intervention to bring the tooth back to its original position. A case of an intruded immature permanent incisor is presented, with a particular emphasis on these critical decisions on repositioning and showing the use of the three modalities of treatment in sequence, in order to achieve an outcome.

Abstract
Quality improvement (QI) is a way through which health care delivery can be made safer and more effective. Various models of quality improvement methods exist in health care today. These models can help guide and manage the process of introducing changes into clinical practice. The aim of this project was to implement the use of a delirium assessment tool into three adult critical care units within the same hospital using a QI approach. The objective was to improve the identification and management of delirium. Using the Model for Improvement framework, a multidisciplinary working group was established. A delirium assessment tool was introduced via a series of educational initiatives. New local guidelines regarding the use of delirium assessment and management for the multidisciplinary team were also produced. Audit data were collected at 6 weeks and 5 months post-implementation to evaluate compliance with the use of the tool across three critical care units within a single hospital in London. At 6 weeks, in 134 assessment points out of a possible 202, the tool was deemed to be used appropriately, meaning that 60% of patients received timely assessment; 18% of patients were identified as delirious in audit one. Five months later, only 95 assessment points out of a possible 199 were being appropriately assessed (47%); however, a greater number (32%) were identified as delirious. This project emphasizes the complexity of changing practice in a large busy critical care centre. Despite an initial increase in delirium assessment, this was not sustained over time. The use of a QI model highlights the continuous process of embedding changes into clinical practice and the need to use a QI method that can address the challenging nature of modern health care. QI models guide changes in practice. Consideration should be given to the type of QI model used.
