Abstract
OBJECTIVES Pulmonary carcinoma is uncommon in cats and reporting of outcomes following medical treatment is limited, especially in presence of metastases. The aim of this study was to describe the outcome of cats affected by metastatic primary pulmonary carcinoma and to evaluate the tolerability of palliative treatment in this patient population. MATERIALS AND METHODS Medical records were searched for cats with a cytological or histopathological diagnosis of primary pulmonary carcinoma and evidence of metastatic disease. Cats were treated with antineoplastic agents, corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs) or received no systemic treatment. Cases in which thoracic CT was not performed, and those lacking definitive diagnosis by cytology or histopathology or receiving curative-intent surgery were excluded. RESULTS Thirty-four cats were identified: 18 were treated with antineoplastic agents and 16 received corticosteroids, NSAIDs or no treatment. Presenting clinical signs included coughing (53%), tachypnoea (26%), gastrointestinal signs (35%) and lethargy (18%). CT scan identified metastases to the lung parenchyma in all cases and additional metastatic lesions in 10 of 34 (59%) cases; pleural effusion was detected in 11 cases (32%). The overall median survival time for all cats was 64 days [range 1-1352 days; 95% confidence interval (CI) 48-164]. Presence of respiratory signs at presentation was the only factor influencing survival in the multivariable analysis. CLINICAL SIGNIFICANCE Medical treatment was well tolerated and appeared to palliate clinical signs in cats with metastatic pulmonary carcinoma, albeit with a modest duration and short overall survival. The role and benefit of chemotherapy/antineoplastic agents versus conventional palliative drugs in this setting remains unclear.

Abstract
Abstract
BACKGROUND
A 10-year retrospective case series was undertaken of all patients who had a tissue diagnosis of a World Health Organisation (WHO) Grade II glioma, i.e. low grade glioma (LGGM), at the Institute of Neurological Sciences (INS) between January 2010 and January 2020 (NB: pre-2016 World Health Organisation classification). The objective was to assess the correlation of World Health Organisation (WHO) Grade II gliomas to seizure symptomology, intracerebral tumour location, histopathological glioma sub-type and molecular markers including isocitrate dehydrogenase-1 (IDH-1) mutation.
MATERIAL AND METHODS
We extracted data regarding clinical, radiological, histological, molecular discriminators and functional outcomes in patients. The pre-operative symptomology was restricted to seizures, headache and focal neurological deficits.
RESULTS
84 patients underwent resection and had a mean age of 42rs (range: 21-77yrs]). Seizures (NB: pre-2017 International League against Epilepsy classification [ILAE]) occurred in 71% and of these 52% were generalised, 37% partial and 11% mixed. 31% had ongoing seizures postoperatively. Headache occurred in 38% (of these 50% had headache and seizures). Focal neurological deficits (FNDs) occurred in 21% (of these 61% had FNDs and seizures). Seizure, as an isolated pre-operative symptom occurred in 48% patients compared to isolated headache in 10% and isolated FNDs in 4%. Anatomically, 58% of lesions were frontal. The seizure spatial frequency was 60% frontal. Histologically, 60% were diffuse astrocytomas and 40% oligodendrogliomas. Furthermore, 71% of oligodendrogliomas and 49% of diffuse astrocytomas had a frontal location. IDH-1 mutation occurred in 80% patients (75% of these had seizures) and of these 66% were frontal.
CONCLUSIONS
Our analysis confirms a correlation between incidence of seizures, frontal lobar location, histopathological subtype and IDH-1 mutations (p = <0.05

Abstract
Introduction Reductions in exacerbation and hospitalisations are the outcomes rated as most important by people with chronic obstructive pulmonary disease (COPD). Most COPD management is currently based on a reactive approach, and delays in recognising treatable opportunities underpin COPD care quality gaps. Innovations that empower COPD self-management, facilitate integrated clinical care and support delivery of evidence-based treatment interventions are urgently required. Methods and analysis The Remote-Management of COPD: Evaluating the Implementation of Digital Innovation to Enable Routine Care trial is a prospective observational cohort hybrid implementation and effectiveness study that will explore the adoption of a digital service model for people with ‘high-risk’ COPD and evaluate the feasibility of this approach versus current standards of care. People with COPD, who have had recent severe exacerbation and/or COPD–obstructive sleep apnoea overlap or chronic hypercapnic respiratory failure requiring home non-invasive ventilation (NIV) or continuous positive airway pressure (CPAP), with internet access will be recruited into the study and enrolled into the digital service. Study endpoints will examine participant utilisation, clinical service impact and clinical outcomes compared with historical and contemporary control patient data. The digital infrastructure will also provide a foundation to explore the feasibility of approaches to predict outcomes and exacerbation in people with COPD through machine learning analysis. Ethics and dissemination Ethical approval for this clinical trial has been obtained from the West of Scotland Research Ethics Service. The trial will commence in September 2019 for a duration of 2 years. Results will be presented at local, national and international meetings, as well as submission for publication to peer-reviewed journals. Trial registration number NCT04240353.

Abstract
INTRODUCTION The Research and Clinical Trials Therapeutic Radiographers network is a College of Radiographers Specialist Interest Group. It was established to develop and facilitate a support network for therapeutic radiographers working in roles which involve the delivery of radiotherapy clinical trials. Its establishment highlighted the challenges faced by therapeutic radiographers employed in these roles. Consequently, the authors sought to formally capture the working landscape of this subsection of the radiographic workforce, aiming to ascertain any potential barriers to professional development and the increase of clinical trials activity by 15% mandated by NHS England. METHODS A Qualtrics survey was designed, pilot tested and distributed to the sixty-two radiotherapy departments across England and the devolved nations. Departments were questioned on the size, structure and the scope of practice of their radiotherapy research and clinical trials team members. FINDINGS Thirty-nine complete responses were received, providing a response rate of 62%, with each region of the UK represented in the survey. The findings demonstrated issues related to the number of posts affecting capacity, contract status jeopardising the security and effectiveness of their role and the activities specific to research and clinical trials being 'bolted on' to existing roles. Although advanced practice was being undertaken by around a third of this workforce the findings established several barriers including individual/teams' capacity and a perceived lack of support for therapeutic radiographers to progress in clinical trials roles. CONCLUSION The findings illustrate several important implications which if not addressed may not only hinder UK radiotherapy departments to achieve the national increase of 15% of clinical trial activity over the next three years but also restrict the growth in size and scope of professional practice of the workforce. IMPLICATIONS FOR PRACTICE The research and clinical trials workforce need to adopt a collaborative approach to profile raising and establish a standardised professional scope of practice to support growth and recognition of their role.

Abstract
INTRODUCTION Compassion is a poorly understood concept in diagnostic and therapeutic radiography, but an increase in its focus was recommended in the Francis Report (2013). Much of the healthcare literature including policy and protocol has focussed on benchmarking and individualising compassion. Two separately conducted doctoral research projects, one therapeutic and one diagnostic, aimed to conceptualise compassion in order to understand its meaning and behavioural expression. METHODS A constructivist approach was taken with appropriate ethical approval. Patients and carers, student radiographers and radiographers took part in interviews and focus groups and tweets were harvested from a Twitter journal club discussion between radiographers of the second author's published literature review. Data were transcribed and analysed thematically. FINDINGS Key aspects of communication are fundamental to giving compassionate patient-centred care. These include verbal and non-verbal cues, actively listening and engaging and establishing rapport with the patient. Specific skills associated with these are also identified in these studies. CONCLUSION Keeping the patient as a person at the centre of radiographic practice in the rapidly evolving technical and cultural environment in which it exists requires timely and appropriate behavioural expressions of compassion from radiographers deploying a range of highly specific communication and interpersonal skills. IMPLICATIONS FOR PRACTICE When undertaking reflective practice, radiographers could consider key aspects of how they communicate with patients, including: verbal (in particular the language they use with patients and their tone of voice); non-verbal (especially eye contact and smiling and their body language). They could also usefully explore and develop skills in reading their patients' body language as well as their own in order to pick up subtle or hidden cues that might suggest a patient is suffering emotionally or psychologically. Finally, they could think about the sort of targeted questions they could ask of patients when welcoming them into the x-ray or treatment room that would both facilitate the procedure and leave the patient feeling that their radiographer had taken a genuine interest in them and their situation. These reflections could then be used to possibly modify their existing communications with their patients.

Abstract
PURPOSE Human pluripotent stem cell (hPSC)-derived dopaminergic neuron progenitor cells (DAPCs) are a potential therapy for Parkinson's disease (PD). However, their intracranial administration raises safety concerns including uncontrolled proliferation, migration and inflammation. Here, we apply a bimodal imaging approach to investigate the fate of DAPC transplants in the rat striatum. PROCEDURES DAPCs co-expressing luciferase and ZsGreen or labelled with micron-sized particles of iron oxide (MPIOs) were transplanted in the striatum of RNU rats (n = 6 per group). DAPCs were tracked in vivo using bioluminescence and magnetic resonance (MR) imaging modalities. RESULTS Transgene silencing in differentiating DAPCs accompanied with signal attenuation due to animal growth rendered the bioluminescence undetectable by week 2 post intrastriatal transplantation. However, MR imaging of MPIO-labelled DAPCs showed that transplanted cells remained at the site of injection for over 120 days. Post-mortem histological analysis of DAPC transplants demonstrated that labelling with either luciferase/ZsGreen or MPIOs did not affect the ability of cells to differentiate into mature dopaminergic neurons. Importantly, labelled cells did not elicit increased glial reactivity compared to non-labelled cells. CONCLUSIONS In summary, our findings support the transplantation of hPSC-derived DAPCs as a safe treatment for PD.

Abstract
Abstract
Study question
In men and women undergoing IVF are preconceptual circulating metabolites associated with ongoing pregnancy rates?
Summary answer
Preconceptual serum histidine levels, in both women and men were associated with ongoing pregnancy. Several amino acids and lipoproteins exhibited possible sex-specific associations.
What is known already
Preconceptual maternal health has been associated with pregnancy outcomes after IVF. The extent to which this is because of pre-existing metabolic factors related to infertility and the role of paternal metabolic health is unclear.
Study design, size, duration
Cohort of 398 women and 325 male partners prospectively recruited between 1 April 2017 and 31 March 2019.
Participants/materials, setting, methods
Women and their male partners intending to undergo assisted conception at a University Hospital, had detailed pre-treatment phenotyping including non-fasting serum lipids, lipoprotein subclasses, and low-molecular weight metabolites (including amino acids, glycolysis and inflammatory markers) (155 metabolites) quantified by NMR spectroscopy. Multivariable linear and logistic regression were used to examine the associations of pre-treatment serum metabolic profiles, with ongoing pregnancy at 20 weeks gestation with adjustment for confounders.
Main results and the role of chance
392 women and 322 men proceeded to IVF treatment, with an overall ongoing pregnancy rate of 47.2% (95% CI 0.42, 0.52) per cycle started and a multiple pregnancy rate of 1.1% (95%CI 0.0, 0.04). In both females and males in confounder adjusted analyses histidine was associated with the chance of ongoing pregnancy, with similar magnitudes in each parent (OR 1.28 (95% CI 1.03, 1.60) per one standard deviation (SD) increase for males and OR 1.26 (95% CI 0.99, 1.60) per one SD increase for females). In females Alanine (OR = 1.31 (1.05, 1.64)), Isoleucine (OR = 1.28 (1.02, 1.61)) and Leucine (OR = 1.24 (0.99, 1.55)) had a positive association with ongoing pregnancy, while in males, pyruvate (OR = 1.30 (1.02,1.66)) exhibited a positive association with ongoing pregnancy. In both parents, associations of lipids, lipoproteins sub-particles and fatty acids with pregnancy were closer to the null.
Limitations, reasons for caution
Suggestive parental differences could be due to chance. Patients were relatively homogenous undertaking their first IVF cycle and the results may not be generalisable to other clinical populations.
Wider implications of the findings: This study provides data on a range of metabolic pathways and their association with ongoing pregnancy following IVF. The identification of potentially relevant clinical effect sizes in both men and women warrants further exploration.

Abstract
BACKGROUND Fruit and vegetable consumption in the United Kingdom is currently well below recommended levels, with a significant associated public health burden. The United Kingdom has committed to reducing its carbon emissions to net zero by 2050, and this transition will require shifts towards plant-based diets. OBJECTIVE The aim was to quantify the health effects, environmental footprints, and cost associated with 4 different pathways to meeting the United Kingdom's "5-a-day" recommendation for fruit and vegetable consumption. METHODS Dietary data based on 18,006 food diaries from 4528 individuals participating in the UK National Diet and Nutrition Survey (2012/13-2016/17) constituted the baseline diet. Linear programming was used to model the hypothetical adoption of the 5-a-day (400 g) recommendation, which was assessed according to 4 pathways differing in their prioritization of fruits versus vegetables and UK-produced versus imported varieties. Increases in fruit and vegetable consumption were substituted for consumption of sweet snacks and meat, respectively. Changes in life expectancy were assessed using the IOMLIFET life table model. Greenhouse gas emissions (GHGEs), blue water footprint (WF), and total diet cost were quantified for each 5-a-day diet. RESULTS Achieving the 5-a-day target in the United Kingdom could increase average life expectancy at birth by 7-8 mo and reduce diet-related GHGEs by 6.1 to 12.2 Mt carbon dioxide equivalents/y; blue WFs would change by -0.14 to +0.07 km3/y. Greater reductions in GHGEs were achieved by prioritizing increased vegetable consumption over fruit, whereas the greatest reduction in WF was obtained by prioritizing vegetable varieties produced in the United Kingdom. All consumption pathways increased diet cost (£0.34-£0.46/d). CONCLUSIONS Benefits to both population and environmental health could be expected from consumption pathways that meet the United Kingdom's 5-a-day target for fruit and vegetables. Our analysis identifies cross-sectoral trade-offs and opportunities for national policy to promote fruit and vegetable consumption in the United Kingdom.

Background
Sarcoidosis is a multi-systemic inflammatory disease of unknown etiology. Cardiac Sarcoidosis (CS) has been reported in as much as 25% of patients with systemic involvement. 18Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) has a high diagnostic sensitivity/specificity in the diagnosis of CS.
Purpose
The aim of this review is to summarize evidence on the prognostic role of FDG PET.
Methods
Studies were identified by searching MEDLINE from inception to October 2020. Medical Subject Headings (MeSH) terms for sarcoidosis; cardiac and FDG PET imaging were used. Studies of any design assessing the prognostic role of FDG PET in patients with either suspected or confirmed cardiac sarcoidosis imaging done at baseline were included. Abnormal PET was defined as abnormal metabolism (presence of focal or focal-on-diffuse uptake of FDG) OR abnormal metabolism and a perfusion defect. Studies reporting any outcome measure were included. Pooled risk ratio for the composite outcome of MACE was done.
Results
A total of 6 studies were selected for final inclusion (515 patients, 53.4% women, 19.8% racial minorities.) Studies were institution based, retrospective in design and enrolled consecutive patients. All were observational in nature and published in English. All studies used a qualitative assessment of PET scans (abnormal FDG uptake with or without abnormal perfusion). Two studies assessed quantitative metrics (summed stress score in segments with abnormal FDG uptake, standardized uptake value and cardiac metabolic activity.) All studies reported Major Adverse Cardiovascular Events (MACE) as a composite outcome. After a mean follow up ranging from 1.4 to 4.1 years, there were a total of 105 MACE. All studies included death (either all-cause death or sudden cardiac death) and ventricular arrhythmia (ventricular tachycardia or ventricular fibrillation) as a component of MACE. Four of the six studies adjusted for several characteristics in their analysis. All four studies used Left Ventricular Ejection Fraction (LVEF). However, other adjustment variables were not consistent across studies. Five studies found a positive prognostic association with the primary outcome, two of which assessing right ventricular uptake.
Conclusion
Although available evidence indicates FDG PET can be used in the risk stratification of patients with CS, our findings show further studies are needed to quantify the effect in this patient group.

Abstract
Increasing recognition of the heterogeneous nature of endometrial cancer, the excellent prognosis of low-risk cases and improvements in risk stratification offer opportunities for innovative, personalised follow-up strategies. This review article outlines the evidence base for alternative follow-up strategies in the different risk categories of endometrial cancer, cancer survivorship programmes and considers future directions in endometrial cancer follow-up, including emerging new techniques, such as the liquid biopsy, and opportunities for combining molecular and clinicopathological features to personalise endometrial cancer follow-up.

Abstract
Abstract
Background
Hip fractures have a mortality rate of 20% in the year following the fracture. Therefore, patients presenting with hip fractures should be assessed and prescribed anti-resorptive bone protective therapy (ABPT) to reduce the risk of further fractures. In our institution, this decision is undertaken by a specialist only. Purpose: The objective of this study is to compare the proportion of patients commenced on ABPT by surgical interns following the introduction of a Clinical Decision Support System (CDSS) in January 2020 to support appropriate ABPT prescribing amongst non-specialists.
Methods
The study compares the orthogeriatric patient cohort before and after CDSS introduction within the same time period (Jan 1st to June 30th) in 2019 and 2020. Data were extracted from the Irish Hip Fracture Database and statistically analyzed using SPSS. The Mann–Whitney two-tailed test was employed to calculate statistical significance.
Results
In 2019, 31% (55/178) of patients admitted during the study period (n = 178) did not receive orthogeriatric specialist input and only 27% (15/55) of these had ABPT prescribed during their admission. In 2020, 17% (32/185) of patients admitted during the study period (n = 185) did not receive specialist input; however, 44% (14/32) of these were commenced on ABPT. Overall, more patients were prescribed ABPT in 2020 (78%;146/185), as compared to 55% (98/178) in 2019 (z-score 6.57069; p-value <0.01). The number of patients awaiting specialist outpatient appointments before being prescribed ABPT also dropped from 40% (71/178) in 2019 to 13% (24/185) in 2020 (p-value <0.01).
Conclusion
This study highlighted the significance of a CDSS to improve inpatient ABPT prescribing by non-specialists and to reduce outpatient specialist appointments. This could have a major impact on the long-term reduction of mortality rates amongst orthogeriatric patients and the reduction of future healthcare costs.

Abstract
AIMS Target delineation uncertainty is arguably the largest source of geometric uncertainty in radiotherapy. Several factors can affect it, including the imaging modality used for delineation. It is accounted for by applying safety margins to the target to produce a planning target volume (PTV), to which treatments are designed. To determine the margin, the delineation uncertainty is measured as the delineation error, and then a margin recipe used. However, there is no published evidence of such analysis for recurrent gynaecological cancers (RGC). The aims of this study were first to quantify the delineation uncertainty for RGC gross tumour volumes (GTVs) and to calculate the associated PTV margins and then to quantify the difference in GTV, delineation uncertainty and PTV margin, between a computed tomography-magnetic resonance imaging (CT-MRI) and MRI workflow. MATERIALS AND METHODS Seven clinicians delineated the GTV for 20 RGC tumours on co-registered CT and MRI datasets (CT-MRI) and on MRI alone. The delineation error, the standard deviation of distances from each clinician's outline to a reference, was measured and the required PTV margin determined. Differences between using CT-MRI and MRI alone were assessed. RESULTS The overall delineation error and the resulting margin were 3.1 mm and 8.5 mm, respectively, for CT-MRI, reducing to 2.5 mm and 7.1 mm, respectively, for MRI alone. Delineation errors and therefore the theoretical margins, varied widely between patients. MRI tumour volumes were on average 15% smaller than CT-MRI tumour volumes. DISCUSSION This study is the first to quantify delineation error for RGC tumours and to calculate the corresponding PTV margin. The determined margins were larger than those reported in the literature for similar patients, bringing into question both current margins and margin calculation methods. The wide variation in delineation error between these patients suggests that applying a single population-based margin may result in PTVs that are suboptimal for many. Finally, the reduced tumour volumes and safety margins suggest that patients with RGC may benefit from an MRI-only treatment workflow.

Abstract
Microplastic (MP) particles are pollutants of global concern and are ubiquitously distributed in the ocean by physical and biological processes. It has been shown that zooplankton can ingest MP yet the interaction between ciliates and MP is still poorly understood. The discrimination and preferential uptake of MP rather than algal prey by ciliates was assessed in this study. The ciliate Sterkiella sp. was fed a diet that consisted of only Isochrysis galbana or a mixture of the same algae and similarly sized polyethylene beads in a 1:3 ratio. Significant, preferential MP grazing was observed in the Plastic-Algae treatment, which is the first reported evidence of proto-zooplankton preferentially ingesting MP over algal food. The mixed treatment contained fecal pellets with embedded MP. Preferential uptake of MP suggests that Sterkiella sp. is capable of ingesting and then "repackaging" MP that would otherwise be too small for larger taxa. This process would thus offer a mechanism for the reintroduction of MP into different compartments of the marine food web. As a consequence, it is necessary to account for small-sized MP (<5 μm) particles, that may have additional and yet unknown, impacts on marine food webs.

Abstract
Social support impacts recovery after stroke. Patient centered navigation programs provide social support and have shown benefit with other patient populations. The purpose of this study is to determine if there is a difference in outcomes for stroke survivors and caregivers who receive navigation services post-discharge. The study used a multi-center quasi-experimental before-after design to examine the impact of a telephone-based stroke navigation. Selected recruitment sites were nine facilities without navigation programs. Facilities provided information to survivors and caregivers about Stroke Recovery Navigator (SRN) prior to discharge and made referrals to the program. Participants were randomized into control and intervention groups using a computer-generated coin flip. Navigators completed telephone assessments within a week of referral. Navigators received the following trainings: Patient Navigation Fundamentals, motivational interviewing, and mental health first aid. The Reintegration to Normal Living (RNLI) scale was completed by all survivors and the Zarit Caregiver Burden scale was completed by all caregivers. The control group completed the initial and final assessments using these tools. In addition to these assessments, the intervention group received an individualized navigation plan and weekly contact by the SRN. The study randomized 301 individuals (82 caregivers, 219 survivors), with completion rate of 32%. Caregiver demographic characteristics and baseline caregiver burden scores were not statistically significant. Caregiver burden in the intervention group were lower compared to the control group, but not statistically significant (p=0.25). Demographic characteristics for survivors were similar between groups. RNLI score for survivors was slightly higher for the intervention group (p<0.10). To achieve statistical significance additional participants were needed.
In conclusion differences in quality of life for survivors and caregivers were not statistically significant between the groups. Additional information on the benefits of an SRN program is needed to support its implementation. However, important lessons were learned to improve such program and its design.

Abstract
Abstract
Background
The impact of catheter ablation (CA) for atrial fibrillation (AF) in patients with heart failure with preserved ejection fraction (HFpEF) is unknown.
Objectives
To determine whether CA for AF reverses adverse haemodynamic changes associated with HFpEF.
Methods
Consecutive consenting patients with EF ≥50% scheduled for index CA underwent baseline exercise right heart catheterisation (exRHC), cardiac output (CO) measurement, cardiac MRI, echocardiogram, QOL questionnaires and BNP testing. HFpEF was defined by resting pulmonary capillary wedge pressure (PCWP) ≥15mmHg or peak exercise PCWP ≥25 mmHg during exRHC. Patients with HFpEF were offered follow-up exRHC ≥6 months post-CA.
Results
Of 252 patients scheduled for CA between April 2017 and Sept 2019, 131 (51.9%) qualified for inclusion, 65 (49.6%) consented to exRHC and 11 (16.9%) were excluded due to a subsequent decrease in EF (10) and uncontrolled hypertension (1). Fifty-four underwent exRHC, with 35 (65%) meeting criteria for HFpEF. Of them 26 (74.3%) who underwent CA, 20 (77%) had a follow up exRHC at 12±6 months follow-up, showing an overall decrease in peak exercise PCWP from 30.3±4.2 to 26.8±4.7 mmHg (p<0.05). Patients without arrhythmia recurrence showed significant improvements in peak exercise PCWP (29.2±3.7 to 22.9±2.0 mmHg (p<0.01). Their cardiac output increased from 10.3±3.0 to 12.1±4.0 mmHg p=0.1), and BNP decreased from (94.6±101.6 to 38.0±34.0 mmHg (p=0.06),whereas those with arrhythmia recurrence did not. Overall, 9 patients (45.0%) no longer met criteria for HFpEF.
Conclusion
There is a high prevalence of HFpEF in people referred for AF ablation. Successful CA for AF reverses the adverse haemodynamic changes associated with HFpEF
Changes in PCWP following AF ablation

Abstract
Domestic contribution to total fruit and vegetable supply in the UK decreased from 42% in 1987 to 22% in 2013. The impact of this changing pattern of UK fruit and vegetable imports, from countries with different vulnerabilities to projected climate change, on the resilience of the UK food system is currently unknown. Here, we used the UN FAO bilateral trade database over a period of 27 years to estimate changes in fruit and vegetable supply in the UK, and the NDGAIN climate vulnerability categories to assess the climate vulnerability of countries supplying fruit and vegetables to the UK. The diversity of fruit and vegetable supply has increased from 21 crops, comprising the top 80% of all fruit and vegetables supplied to the UK in 1987, to 34 crops in 2013. The contribution of tropical fruits has rapidly increased while that of more traditional vegetables, such as cabbages and carrots, has declined. The proportion of fruit and vegetables supplied to the UK market from climate vulnerable countries increased from 20% in 1987 to 32% in 2013. Sensitivity analyses - using climatic and freshwater availability indicators - supported these findings. Increased reliance on fruit and vegetable imports from climate vulnerable countries could negatively affect the availability, price and consumption of fruit and vegetables in the UK, affecting dietary intake and health particularly of older people and low-income households. Inter-sectoral actions across agriculture, health, environment, and trade are critical in both the UK and countries that export to the UK to increase the resilience of the food system, and support population health.

Abstract
BACKGROUND AND PURPOSE There are only few data and lack of consensus regarding antiplatelet management for carotid stent placement in the setting of endovascular stroke treatment. We aimed to develop a consensus-based algorithm for antiplatelet management in acute ischemic stroke patients undergoing endovascular treatment and simultaneous emergent carotid stent placement. MATERIALS AND METHODS We performed a literature search and a modified Delphi approach used Web-based questionnaires that were sent in several iterations to an international multidisciplinary panel of 19 neurointerventionalists from 7 countries. The first round included open-ended questions and formed the basis for subsequent rounds, in which closed-ended questions were used. Participants continuously received feedback on the results from previous rounds. Consensus was defined as agreement of ≥70% for binary questions and agreement of ≥50% for questions with >2 answer options. The results of the Delphi process were then summarized in a draft manuscript that was circulated among the panel members for feedback. RESULTS A total of 5 Delphi rounds were performed. Panel members preferred a single intravenous aspirin bolus or, in jurisdictions in which intravenous aspirin is not available, a glycoprotein IIb/IIIa receptor inhibitor as intraprocedural antiplatelet regimen and a combination therapy of oral aspirin and a P2Y12 inhibitor in the postprocedural period. There was no consensus on the role of platelet function testing in the postprocedural period. CONCLUSIONS More and better data on antiplatelet management for carotid stent placement in the setting of endovascular treatment are urgently needed. Panel members preferred intravenous aspirin or, alternatively, a glycoprotein IIb/IIIa receptor inhibitor as an intraprocedural antiplatelet agent, followed by a dual oral regimen of aspirin and a P2Y12 inhibitor in the postprocedural period.

Abstract
BACKGROUND AND PURPOSE There is a paucity of data regarding antiplatelet management strategies in the setting of stent-assisted coiling/flow diversion for ruptured intracranial aneurysms. This study aimed to identify current challenges in antiplatelet management during stent-assisted coiling/flow diversion for ruptured intracranial aneurysms and to outline possible antiplatelet management strategies. MATERIALS AND METHODS The modified DELPHI approach with an on-line questionnaire was sent in several iterations to an international, multidisciplinary panel of 15 neurointerventionalists. The first round consisted of open-ended questions, followed by closed-ended questions in the subsequent rounds. Responses were analyzed in an anonymous fashion and summarized in the final manuscript draft. The statement received endorsement from the World Federation of Interventional and Therapeutic Neuroradiology, the Japanese Society for Neuroendovascular Therapy, and the Chinese Neurosurgical Society. RESULTS Data were collected from December 9, 2019, to March 13, 2020. Panel members achieved consensus that platelet function testing may not be necessary and that antiplatelet management for stent-assisted coiling and flow diversion of ruptured intracranial aneurysms can follow the same principles. Preprocedural placement of a ventricular drain was thought to be beneficial in cases with a high risk of hydrocephalus. A periprocedural dual, intravenous, antiplatelet regimen with aspirin and a glycoprotein IIb/IIIa inhibitor was preferred as a standard approach. The panel agreed that intravenous medication can be converted to oral aspirin and an oral P2Y12 inhibitor within 24 hours after the procedure. CONCLUSIONS More and better data on antiplatelet management of patients with ruptured intracranial aneurysms undergoing stent-assisted coiling or flow diversion are urgently needed. Panel members in this DELPHI consensus study preferred a periprocedural dual-antiplatelet regimen with aspirin and a glycoprotein IIb/IIIa inhibitor.

Abstract
BACKGROUND Digital interventions targeting common mental disorders (CMDs) or symptoms of CMDs are growing rapidly and gaining popularity, probably in response to the increased prevalence of CMDs and better awareness of early help-seeking and self-care. However, no previous systematic reviews that focus on these novel interventions were found. OBJECTIVE This systematic review aims to scope entirely web-based interventions that provided screening and signposting for treatment, including self-management strategies, for people with CMDs or subthreshold symptoms. In addition, a meta-analysis was conducted to evaluate the effectiveness of these interventions for mental well-being and mental health outcomes. METHODS Ten electronic databases including MEDLINE, PsycINFO, and EMBASE were searched from January 1, 1999, to early April 2020. We included randomized controlled trials (RCTs) that evaluated a digital intervention (1) targeting adults with symptoms of CMDs, (2) providing both screening and signposting to other resources including self-care, and (3) delivered entirely through the internet. Intervention characteristics including target population, platform used, key design features, and outcome measure results were extracted and compared. Trial outcome results were included in a meta-analysis on the effectiveness of users' well-being and mental health outcomes. We also rated the meta-analysis results with the Grading of Recommendations, Assessment, Development, and Evaluations approach to establish the quality of the evidence. RESULTS The electronic searches yielded 21 papers describing 16 discrete digital interventions. These interventions were investigated in 19 unique trials including 1 (5%) health economic study. Most studies were conducted in Australia and North America. The targeted populations varied from the general population to allied health professionals. All interventions offered algorithm-driven screening with measures to assess symptom levels and to assign treatment options including automatic web-based psychoeducation, self-care strategies, and signposting to existing services. A meta-analysis of usable trial data showed that digital interventions improved well-being (3 randomized controlled trials [RCTs]; n=1307; standardized mean difference [SMD] 0.40; 95% CI 0.29 to 0.51; I2=28%; fixed effect), symptoms of mental illness (6 RCTs; n=992; SMD -0.29; 95% CI -0.49 to -0.09; I2=51%; random effects), and work and social functioning (3 RCTs; n=795; SMD -0.16; 95% CI -0.30 to -0.02; I2=0%; fixed effect) compared with waitlist or attention control. However, some follow-up data failed to show any sustained effects beyond the post intervention time point. Data on mechanisms of change and cost-effectiveness were also lacking, precluding further analysis. CONCLUSIONS Digital mental health interventions to assess and signpost people experiencing symptoms of CMDs appear to be acceptable to a sufficient number of people and appear to have enough evidence for effectiveness to warrant further study. We recommend that future studies incorporate economic analysis and process evaluation to assess the mechanisms of action and cost-effectiveness to aid scaling of the implementation.

Abstract
In this study, we measured the performance of medical students and anaesthetists using a new tracker needle during simulated sciatic nerve block on soft embalmed cadavers. The tracker needle incorporates a piezo element near its tip that generates an electrical signal in response to insonation. A circle, superimposed on the ultrasound image surrounding the needle tip, changes size and colour according to the position of the piezo element within the ultrasound beam. Our primary objective was to compare sciatic block performance with the tracker switched on and off. Our secondary objectives were to record psychometrics, procedure efficiency, participant self-regulation and focused attention using eye-tracking technology. Our primary outcome measures were the number of steps successfully performed and the number of errors committed during each block. Videos were scored by trained experts using validated checklists. Sequential tracker activation and deactivation was randomised equally within subjects. With needle activation, steps improved in 10 (25%) subjects and errors reduced in six (15%) subjects. The most important steps were: needle tip identification before injection, OR (95%CI) 2.12 (1.61-2.80; p < 0.001); and needle tip identification before advance of the needle, 1.80 (1.36-2.39; p < 0.001). The most important errors were: failure to identify the needle tip before injection, 2.40 (1.78-3.24; p < 0.001); and failure to quickly regain needle tip position when tip visibility was lost, 2.03 (1.5-2.75; p < 0.001). In conclusion, needle-tracking technology improved performance in a quarter of subjects.

Abstract
In this work we report on the implementation of methods for data processing signals from microelectrode arrays (MEA) and the application of these methods for signals originated from two types of MEAs to detect putative neurons and sort them into subpopulations. We recorded electrical signals from firing neurons using titanium nitride (TiN) and boron doped diamond (BDD) MEAs. In previous research, we have shown that these methods have the capacity to detect neurons using commercially-available TiN-MEAs. We have managed to cultivate and record hippocampal neurons for the first time using a newly developed custom-made multichannel BDD-MEA with 20 recording sites. We have analysed the signals with the algorithms developed and employed them to inspect firing bursts and enable spike sorting. We did not observe any significant difference between BDD- and TiN-MEAs over the parameters, which estimated spike shape variability per each detected neuron. This result supports the hypothesis that we have detected real neurons, rather than noise, in the BDD-MEA signal. BDD materials with suitable mechanical, electrical and biocompatibility properties have a large potential in novel therapies for treatments of neural pathologies, such as deep brain stimulation in Parkinson's disease.

Abstract
Introduction
Obstructive sleep apnea (OSA) presents in 2-5 % of youth and has been consistently linked to sleepiness, cognitive deficits, behavior difficulties, and cardiovascular morbidity. PAP effectively treats OSA, however, nonadherence is the most common cause of PAP treatment failure in children. Few adherence interventions have been empirically studied for youth with OSA. The STARS (Steps Towards Achieving Restful Sleep) Clinic is a behavioral program to optimize child tolerance to PAP therapy through a parent class, and in vivo practice. The goal of the study was to examine parent knowledge and self-efficacy following participation in STARS, and associations with subsequent PAP adherence.
Methods
A retrospective chart review was conducted for patients in the STARS program. Items queried included patient demographics, diagnostic and treatment characteristics, pre- and post- STARS responses to a parent self-efficacy and knowledge questionnaire, and polysomnography and PAP adherence data. Paired-samples t-tests examined changes in parent self-efficacy and knowledge pre- to post STARS, and regression analyses examined associations between self-efficacy and knowledge with demographics, treatment-related characteristics, and PAP adherence.
Results
130 patients completed the STARS program from October 2016 to February 2019. Participants were 8.3 years old ±6.3, 63% male, 57% white, 33% Hispanic, with severe OSA (OAHI =22 ±33). Most participants (87%) had at least one medical comorbidity (e.g, Down Syndrome, 41%). Both parent knowledge and self-efficacy increased significantly from pre- to post- STARS. Approximately 60% of patients were adherent following STARS (defined as ≥4 h use and ≥70% of days used). Higher post- knowledge, but not efficacy score, was significantly associated with better PAP adherence.
Conclusion
Parent knowledge and self-efficacy for PAP improved following the STARS program, and greater knowledge was associated with better adherence. Future research evaluating the efficacy and effectiveness of the STARS program is needed but preliminary evidence suggests it may be a promising model for improving youth PAP adherence.

Abstract
UNLABELLED Gaining full benefits from osteoporosis medications requires long-term treatment. Investigating the real-world persistence of women receiving osteoporosis medications in the UK, we found that most patients stop treatment within a year. To prevent osteoporotic fragility fractures, long-term treatment persistence must be improved. INTRODUCTION Persistence with osteoporosis therapies has historically been poor. To treat this chronic and progressive disease, it is essential that patients receive the full benefit of these medications. We estimated persistence and compliance with osteoporosis therapies in a large sample of postmenopausal women in the UK. METHODS Data were obtained from the Clinical Practice Research Datalink for all women aged 50 years and over or women with early menopause, who received at least one prescription in primary care for any licensed osteoporosis therapy between January 1, 2010 and December 31, 2015. Persistence and compliance at 24 months (primary objective) and at 5 years (exploratory objective) were estimated in three patient cohorts: "All Patients," "Naïve Patients," and "Drug-Specific." RESULTS The All Patients cohort included 72,256 women. Persistence with any therapy was 56.1%, 43.6%, 36.4%, and 31.0% at 6, 12, 18, and 24 months, respectively, and 23.2% and 13.1% at 3 years and 5 years, respectively. Patients were generally more persistent and compliant if evaluated from their first exposure to osteoporosis therapy (Naïve Patients cohort). In the drug-specific analysis, 64% of patients receiving denosumab (administered subcutaneously every 6 months) were persistent at 24 months compared with 28% and 23% of those taking oral bisphosphonates and intravenous bisphosphonates, respectively. CONCLUSIONS Only about one in three patients who received osteoporosis therapy continued to be on treatment after 2 years. There is a need to improve persistence with osteoporosis therapy, especially for high-risk patients.

Abstract
OBJECTIVE Dystonia is a complex movement disorder. Research progress has been difficult, particularly in developing widely effective therapies. This is a review of the current state of knowledge, research gaps, and proposed research priorities. METHODS The NIH convened leaders in the field for a 2-day workshop. The participants addressed the natural history of the disease, the underlying etiology, the pathophysiology, relevant research technologies, research resources, and therapeutic approaches and attempted to prioritize dystonia research recommendations. RESULTS The heterogeneity of dystonia poses challenges to research and therapy development. Much can be learned from specific genetic subtypes, and the disorder can be conceptualized along clinical, etiology, and pathophysiology axes. Advances in research technology and pooled resources can accelerate progress. Although etiologically based therapies would be optimal, a focus on circuit abnormalities can provide a convergent common target for symptomatic therapies across dystonia subtypes. The discussions have been integrated into a comprehensive review of all aspects of dystonia. CONCLUSION Overall research priorities include the generation and integration of high-quality phenotypic and genotypic data, reproducing key features in cellular and animal models, both of basic cellular mechanisms and phenotypes, leveraging new research technologies, and targeting circuit-level dysfunction with therapeutic interventions. Collaboration is necessary both for collection of large data sets and integration of different research methods.

Abstract
Cases from the ongoing outbreak of atypical pneumonia caused by the 2019 novel coronavirus (2019-nCoV) exported from mainland China can lead to self-sustained outbreaks in other populations. Internationally imported cases are currently being reported in several different locations. Early detection of imported cases is critical for containment of the virus. Based on air travel volume estimates from Wuhan to international destinations and using a generalized linear regression model we identify locations which may potentially have undetected internationally imported cases.

Abstract
Abstract
Background
The European Working Group on Sarcopenia in Older People 2 (EWGSOP2) guidelines have recently been published to aid diagnosis of sarcopenia in the clinical setting and to allow for better comparison between research studies. The guidelines recommend several different tests for diagnosing sarcopenia. We hypothesised that the prevalence of sarcopenia might vary depending on which tests are used.
Methods
We used data from Wave 3 of the Lothian Birth Cohort 1936 study, a longitudinal ageing study of healthy, community dwelling older adults (n= 697, 52% men, mean age 76y), to assess the prevalence of sarcopenia using the suggested cut-offs in the EWGSOP2 guidelines. Probable sarcopenia was defined as low muscle strength (measured by handgrip strength and 5x chair stand test), confirmed sarcopenia was defined as low muscle strength + low lean mass (measured by bioimpedance analysis), and severe sarcopenia was defined as confirmed sarcopenia + low muscle performance (measured by gait speed and short physical performance battery score). SPSS version 24.0 was used for statistical analysis.
Results
The maximum prevalence of probable sarcopenia was 24.2% in men and 24.8% in women, of confirmed sarcopenia was 7.4% in men and 11.0% in women, and of severe sarcopenia was 4.6% in men and 5.9% in women, when either of the cut-offs for muscle strength +/- muscle performance were met. When using only one measure of muscle strength +/- performance, rates of probable sarcopenia ranged from 7.7% to 21.1% in men and 5.9% to 21.3% in women; rates of confirmed sarcopenia ranged from 3.9% to 5.3% in men and 5.1% to 9% in women; and rates of severe sarcopenia ranged from 1.4% to 3.9% in men and from 2.0% to 5.1% in women.
Conclusions
In a UK-based longitudinal ageing study we found that the prevalence of probable, confirmed and severe sarcopenia varied widely using the EWGSOP2 guidelines depending on which identifying tests were used. We found that the cut-off points suggested for some of the measures in the guidelines are not comparable and may lead to differing groups being identified as sarcopenic between different trials. We suggest modification of the cut-offs to adjust for this.

Abstract
Background Full contact team sports, such as rugby union, have high incidences of injury. Injury surveillance studies underpin player welfare programmes in rugby union. Objective To determine the incidence, severity, nature and causes of injuries sustained during the Rugby World Cup 2019. Methods A prospective, whole population study following the definitions and procedures recommended in the consensus statement for epidemiologic studies in rugby union. Output measures included players' age (years), stature (cm), body mass (kg), playing position, and group-level incidence (injuries/1000 player-hours), severity (days-absence), injury burden (days absence/1000 player-hours), location (%), type (%) and inciting event (%) of injuries. Results Overall incidences of injury were 79.4 match injuries/1000 player-match-hours (95% CI: 67.4 to 93.6) and 1.5 training injuries/1000 player-training-hours (95% CI: 1.0 to 2.3). The overall mean severity of injury was 28.9 (95% CI: 20.0 to 37.8) days absence during matches and 14.8 (95% CI: 4.1 to 25.5) days absence during training. The most common locations and types of match injuries were head/face (22.4%), posterior thigh (12.6%), ligament sprain (21.7%) and muscle strain (20.3%); the ankle (24.0%), posterior thigh (16.0%), muscle strain (44.0%) and ligament sprain (16.0%) were the most common locations and types of injuries during training. Tackling (28.7%), collisions (16.9%) and running (16.9%) were responsible for most match injuries and non-contact (36.0%) and contact (32.0%) rugby skills activities for training injuries. Conclusion The incidence, severity, nature and inciting events associated with match and training injuries at Rugby World Cup 2019 were similar to those reported for Rugby World Cups 2007, 2011 and 2015.
