Abstract
OBJECTIVE To analyze the characteristics and variables associated with prolonged noninvasive ventilation performed completely in Emergency Departments (NIV-ED) and its influence upon effectiveness. DESIGN A prospective, multicenter, observational multipurpose cohort study was carried out. SETTING VNICAT Registry. SUBJECTS Patients in which NIV-ED was performed in 11 Catalan hospitals in the months of February or March 2015. INTERVENTION No. VARIABLES The study variable was NIV-ED, which as a function of time was defined as prolonged or not prolonged. The efficacy variable was the success of the technique in terms of patient improvement. RESULTS A total of 125 patients were included, with a median NIV-ED duration of 12 h, which was the cut-off point for the comparator groups. In 60 cases (48%) NIV-ED was not prolonged (<12 h), while in 65 cases (52%) ventilation was prolonged (≥12 h). Non-prolonged NIV-ED was associated to the indication of acute heart failure and prolonged ventilation to the presence of diabetes. There were no differences between non-prolonged and prolonged NIV-ED in terms of efficacy, and the success rate in terms of improvement was 68.3% and 76.9%, respectively, with an adjusted odds ratio of 1.49 (95%CI 0.61-3.60). CONCLUSIONS Prolonged NIV-ED is a frequent situation, but few variables associated to it have been studied. The presence of prolonged ventilation did not influence the success rate of NIV.

Abstract
INTRODUCTION The COVID-19 pandemic has led to over 100 million cases worldwide. The UK has had over 4 million cases, 400 000 hospital admissions and 100 000 deaths. Many patients with COVID-19 suffer long-term symptoms, predominantly breathlessness and fatigue whether hospitalised or not. Early data suggest potentially severe long-term consequence of COVID-19 is development of long COVID-19-related interstitial lung disease (LC-ILD). METHODS AND ANALYSIS The UK Interstitial Lung Disease Consortium (UKILD) will undertake longitudinal observational studies of patients with suspected ILD following COVID-19. The primary objective is to determine ILD prevalence at 12 months following infection and whether clinically severe infection correlates with severity of ILD. Secondary objectives will determine the clinical, genetic, epigenetic and biochemical factors that determine the trajectory of recovery or progression of ILD. Data will be obtained through linkage to the Post-Hospitalisation COVID platform study and community studies. Additional substudies will conduct deep phenotyping. The Xenon MRI investigation of Alveolar dysfunction Substudy will conduct longitudinal xenon alveolar gas transfer and proton perfusion MRI. The POST COVID-19 interstitial lung DiseasE substudy will conduct clinically indicated bronchoalveolar lavage with matched whole blood sampling. Assessments include exploratory single cell RNA and lung microbiomics analysis, gene expression and epigenetic assessment. ETHICS AND DISSEMINATION All contributing studies have been granted appropriate ethical approvals. Results from this study will be disseminated through peer-reviewed journals. CONCLUSION This study will ensure the extent and consequences of LC-ILD are established and enable strategies to mitigate progression of LC-ILD.

Abstract
Emphysema is one of the most common pulmonary comorbidities of idiopathic pulmonary fibrosis (IPF), presenting in about one-third of IPF patients [1]. The term combined pulmonary fibrosis and emphysema (CPFE) has been used to describe a potential phenotype characterised by the coexistence of upper lobe-predominant emphysema, lower lobe-predominant fibrosis and relative preservation of lung volumes (forced vital capacity; FVC) in the context of a disproportionately reduced gas transfer (diffusing capacity of the lung for carbon monoxide; DLCO) [1–3]. With regard to patient survival, it remains unclear whether mortality in patients with CPFE reflects the cumulative effects of two disease processes (emphysema and fibrosis), or whether CPFE represents a distinct disease phenotype where outcome is worse than the sum of disease parts (emphysema and fibrosis). In patients with combined pulmonary fibrosis and emphysema, emphysema and fibrosis do not have a synergistic effect that results in worsened survival when compared to IPF patients without emphysemahttps://bit.ly/35EJMo6

Abstract
BACKGROUND To describe the number of visits (total and per COVID-19) attended by the Spanish hospital emergency departments (EDs) during the first wave of the pandemic (March-April 2020) compared to the same period in 2019, and to calculate the quantitative changes in healthcare activity and investigate the possible influence of hospital size and COVID-19 seroprevalence. METHOD Cross-sectional study that analyzes the number of visits to Spanish public EDs, reported through a survey of ED chiefs during the study periods. Changes in healthcare activity were described in each autonomous community and com-pared according to hospital size and the provincial impact of the pandemic. RESULTS A total of 187 (66?%) of the 283 Spanish EDs participated in the study. The total number of patients attended de-creased to 49.2?% (<?30?% in the Castilla-La Mancha region), with a 60?% reduction in non-COVID-19 patients (reduction <?50?% in the regions of Asturias and Extremadura). While there were no differences in changes of healthcare activity according to the size of the hospital, there were differences in relation to the provincial impact of the pandemic, with a direct correla-tion related to the decrease in non-COVID-19 activity (the greater the impact, the greater the decrease; R2?=?0.05; p?=?0.002) and an inverse correlation to the overall activity (the greater the impact, the lesser the decrease; R2?=?0.05; p?=?0.002). CONCLUSION There was a very significant decrease in the number of ED visits during the first pandemic wave, although this decrease cannot be explained solely by the local incidence of the pandemic.

Abstract
BACKGROUND This study assessed the contrasting genomic profiles from the primary tumors (PTs), metastatic (MET) sites, and circulating tumor DNA (ctDNA) of patients with prostate cancer (PC). METHODS A total of 1294 PC tissue specimens and 2462 ctDNA specimens underwent hybrid capture-based comprehensive genomic profiling (CGP). Specimens included tissue from PTs; MET biopsies from bone, liver (LIV), lung (LU), brain (BN), lymph node, and soft tissue sites; and ctDNA. RESULTS Differences in alteration frequencies between PT, MET, and ctDNA specimens for selected genes were observed. TMPRSS2:ERG fusion frequencies were similar between PTs and MET sites (35% vs 33%) but varied among MET sites. Genomic alterations (GAs) in AR were lowest in PTs (2%) and highest in MET sites (from 24% in LU to 50% in LIV). BN had the highest genomic alterations/tumor (8) and enrichment for PTEN GAs. The BRCA2 GA frequency varied from 0% in BN to 15% in LIV. ERBB2 amplification was increased in MET sites in comparison with PTs. RB1 GAs were increased in LIV. Biomarkers potentially associated with an anti-PD(L)1 response included CDK12 GAs (16% in LU) and a microsatellite instability-high status (29% in BN). Analyses of ctDNA featured a broad spectrum of GAs similar to those detected across MET sites. CONCLUSIONS CGP of PTs, MET sites, and ctDNA in PC exhibited differences most likely associated with tumor progression, clonal evolution, and exposure to systemic therapies; ctDNA can also capture a broad range of potential therapeutic opportunities for patients with PC.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) and pleuroparenchymal fibroelastosis (PPFE) are known to have poor outcomes but detailed examinations of prognostic significance of an association between these morphologic processes are lacking. METHODS Retrospective observational study of independent derivation and validation cohorts of IPF populations. Upper-lobe PPFE extent was scored visually (vPPFE) as categories of absent, moderate, marked. Computerised upper-zone PPFE extent (cPPFE) was examined continuously and using a threshold of 2·5% pleural surface area. vPPFE and cPPFE were evaluated against 1-year FVC decline (estimated using mixed-effects models) and mortality. Multivariable models were adjusted for age, gender, smoking history, antifibrotic treatment and diffusion capacity for carbon monoxide. FINDINGS PPFE prevalence was 49% (derivation cohort, n = 142) and 72% (validation cohort, n = 145). vPPFE marginally contributed 3-14% to variance in interstitial lung disease (ILD) severity across both cohorts.In multivariable models, marked vPPFE was independently associated with 1-year FVC decline (derivation: regression coefficient 18·3, 95 CI 8·47-28·2%; validation: 7·51, 1·85-13·2%) and mortality (derivation: hazard ratio [HR] 7·70, 95% CI 3·50-16·9; validation: HR 3·01, 1·33-6·81). Similarly, continuous and dichotomised cPPFE were associated with 1-year FVC decline and mortality (cPPFE ≥ 2·5% derivation: HR 5·26, 3·00-9·22; validation: HR 2·06, 1·28-3·31). Individuals with cPPFE ≥ 2·5% or marked vPPFE had the lowest median survival, the cPPFE threshold demonstrated greater discrimination of poor outcomes at two and three years than marked vPPFE. INTERPRETATION PPFE quantification supports distinction of IPF patients with a worse outcome independent of established ILD severity measures. This has the potential to improve prognostic management and elucidate separate pathways of disease progression.

Abstract
Early detection and diagnosis of coronary artery disease could reduce the risk of developing a heart attack. The coronary arteries are optimally visualised using computed tomography coronary angiography (CTCA) imaging. These images are reviewed by specialist radiologists who evaluate the coronary arteries for potential narrowing. A lack of radiologists in the UK is a constraint to timely diagnosis of coronary artery disease, particularly in the acute accident and emergency department setting. The development of automated methods by which coronary artery narrowing can be identified rapidly and accurately are therefore timely. Such complex computer based tools also need to be sufficiently computationally efficient that they can run on servers typically found in hospital settings, where graphical processing units for example are unavailable. We propose a fully automatic two-dimensional Unet model to segment the aorta and coronary arteries on CTCA images. Two models are trained to segment two regions of interest, (1) the aorta and the coronary arteries or (2) the coronary arteries alone. Our method achieves 91.20% and 88.80% dice similarity coefficient accuracy on regions of interest 1 and 2 respectively. Compared with a semi-automatic segmentation method, our model performs better when segmenting the coronary arteries alone. The performance of the proposed method is comparable to existing published two-dimensional or three-dimensional deep learning models. Importantly, the algorithmic and graphical processing unit memory efficiencies are maintained such that the model can be deployed without requiring graphical processing units, and therefore can be used in a hospital setting.

Abstract
Simple Summary Clinically advanced pheochromocytomas and paragangliomas are a rare form of endocrine malignancy which can occur in familial and sporadic clinical settings and feature a variety of genomic alterations. Comprehensive genomic profiling (CGP) was performed to characterize the genomic alterations (GA) in clinically advanced disease to enable the search for potential therapy targets. Although the GA/tumor is relatively low for clinically advanced disease, CGP can reveal important potential targets for therapy in the metastatic setting including RET, NF1 and FGFR1. Based on this data, further study of CGP as a method of developing precision therapies for clinically advanced disease appears warranted. Abstract Patients with clinically advanced paragangliomas (CA-Para) and pheochromocytomas (CA-Pheo) have limited surgical or systemic treatments. We used comprehensive genomic profiling (CGP) to compare genomic alterations (GA) in CA-Para and CA-Pheo to identify potential therapeutic targets. Eighty-three CA-Para and 45 CA-Pheo underwent hybrid-capture-based CGP using a targeted panel of 324 genes. Tumor mutational burden (TMB) and microsatellite instability (MSI) were determined. The GA/tumor frequencies were low for both tumor types (1.9 GA/tumor for CA-Para, 2.3 GA/tumor for CA-Pheo). The most frequent potentially targetable GA in CA-Para were in FGFR1 (7%, primarily amplifications), NF1, PTEN, NF2, and CDK4 (all 2%) and for CA-Pheo in RET (9%, primarily fusions), NF1 (11%) and FGFR1 (7%). Germline mutations in known cancer predisposition genes were predicted in 13 (30%) of CA-Pheo and 38 (45%) of CA-Para cases, predominantly involving SDHA/B genes. Both CA-Para and CA-Para had low median TMB, low PD-L1 expression levels and none had MSI high status. While similar GA frequency is seen in both CA-Para and CA-Para, germline GA were seen more frequently in CA-Para. Low PD-L1 expression levels and no MSI high status argue against strong potential for novel immune checkpoint inhibitors. However, several important potential therapeutic targets in both CA-Para and CA-Para are identified using CGP.

Abstract
BACKGROUND Carcinoma of the urethra (UrthCa) is an uncommon Genitourinary (GU) malignancy that can progress to advanced metastatic disease. METHODS One hundred twenty-seven metastatic UrthCa underwent hybrid capture-based comprehensive genomic profiling to evaluate all classes of genomic alterations (GA). Tumor mutational burden was determined on up to 1.1 Mbp of sequenced DNA, and microsatellite instability was determined on 114 loci. PD-L1 expression was determined by IHC (Dako 22C3). RESULTS Forty-nine (39%) urothelial (UrthUC), 31 (24%) squamous (UrthSCC), 24 (19%) adenocarcinomas NOS (UrthAC), and 12 (9%) clear cell (UrthCC) were evaluated. UrthUC and UrthSCC are more common in men; UrthAC and UrthCC are more common in women. Ages were similar in all 4 groups. GA in PIK3CA were the most frequent potentially targetable GA; mTOR pathway GA in PTEN were also identified. GA in other potentially targetable genes were also identified including ERBB2 (6% in UrthUC, 3% in UrthSCC, and 12% in UrthAC), FGFR1-3 (3% in UrthSCC), BRAF (3% in UrthAC), PTCH1 (8% in UrthCC), and MET (8% in UrthCC). Possibly reflecting their higher GA/tumor status, potential for immunotherapy benefit associated with higher tumor mutational burden and PD-L1 staining levels were seen in UrthUC and UrthSCC compared to UrthAC and UrthCC. Microsatellite instability high status was absent throughout. CONCLUSIONS Comprehensive genomic profiling reveals GA that may be predictive of both targeted and immunotherapy benefit in patients with advanced UrthCa and that could potentially be used in future adjuvant, neoadjuvant, and metastatic disease trials.

Background:Identifying fibrosing interstitial lung disease (ILD) at the earliest opportunity remains one of the most urgent challenges for the effective management of this potentially rapidly progressive and burdensome condition, which is frequently associated with several connective tissue diseases (CTDs). However, knowledge on how to identify early hallmarks and predictors of fibrosing ILD, as well as knowing which steps to take next is frequently lacking in clinical practice.Objectives:This study was conducted to determine whether online independent medical education could improve rheumatologists’ and pulmonologists’ knowledge and competence in identifying and managing progressive fibrosing ILDs earlier in the disease course.Methods:Rheumatologists and pulmonologists participated in five ~10-min presentations about the early identification of fibrosing ILD in patients with or without CTDs and completed all pre- and post-questions.1 The effects of the education on knowledge and competence were assessed using a 3-question, repeated pairs, pre-assessment/post-assessment study design. For all questions combined, the chi-square test assessed differences from pre- to post-assessment. P values <.05 are statistically significant. The activity launched on October 9, 2020, and data were collected through December 18, 2020.Results:Overall significant improvements were seen after participation for both rheumatologists (average correct response rate of 28% at pre-assessment vs 74% at post-assessment; P<.001, representing a 165% relative percentage change [RPC]; N=39), and pulmonologists (average correct response rate of 39% at pre-assessment vs 67% at post-assessment; P<.001, representing a 72% RPC; N=102). Specifically, significant improvements were observed in clinicians’ knowledge of predictors of fibrosing ILD in patients with CTD, as well as competence in selecting the right HRCT parameters to assess prognosis and select a treatment approach to reduce the risk of disease progression (Figure 1).Figure 1.After participating in the activity, 59% of rheumatologists and 50% of pulmonologists had measurable improved confidence related to identifying early disease progression in patients with progressive fibrosing ILDs.Given the very low rates of correct responses at baseline regarding predictors of fibrosing ILD and assessing prognosis, it will be important to continue to reinforce these learnings in ongoing educational programs.Conclusion:This study demonstrates the success of segmented online education in improving rheumatologists’ and pulmonologists’ knowledge and competence in evaluating risk and prognosis of fibrosing ILD and managing patients with CTD-ILDs. This could lead to earlier changes in therapeutic approach for those with signs of progression and result in improved overall outcomes for these patients.References:[1]Kolb M, Maher T, Smith V, Jacob J, Rimekasten G.

Abstract
INTRODUCTION The popularity of day-case arthroplasty has been fuelled by focus on its cost effectiveness for the healthcare system. Safety concerns still remain. The aim of this review was to compare readmission rates after total joint arthroplasty for patients undergoing day-case surgery and for inpatients. METHODS A comprehensive online search of databases was performed for all published articles in the English language evaluating readmission rates after total hip arthroplasty (THA) and total knee arthroplasty (TKA). Seventeen studies were deemed eligible and included in the meta-analysis. RESULTS All studies included in the meta-analysis described readmission rates following THA/TKA. The readmission rate for day-case patients was 1.9% (n=124) whereas for inpatients, it was 2.0% (n=12,399). Compared with inpatient arthroplasty, day-case arthroplasty was associated with lower total readmission rates (odds ratio [OR]: 0.77, 95% confidence interval [CI]: 0.63-0.94, p=0.01). Furthermore, day-case surgery conferred a decrease in readmission rates for both THA (1.3% vs 7.0%) and TKA (2.7% vs 4.3%). Moreover, day-case THA and TKA were both associated with a decreased chance of readmission (OR: 0.27, 95% CI: 0.17-0.42, p<0.00001; and OR: 0.55, 95% CI: 0.42-0.72, p<0.00001 respectively). CONCLUSIONS This review emphasises that with a thoughtful, designated protocol and with careful patient selection, day-case arthroplasty is a safe and effective option.

Abstract
INTRODUCTION The presence of anaemia leads to a worse prognosis in patients with heart failure (HF). There are few data on the impact of anaemia on mortality in patients with acute heart failure (AHF), and the studies available are mainly retrospective, and include hospitalised patients. OBJECTIVE Evaluate the role of anaemia on 30-day and 1-year mortality in patients with AHF attended in hospital emergency departments (HEDs). METHODS We performed a multicentre, observational study of prospective cohorts of patients with AHF. The study variables were: Anaemia (haemoglobin < 12g/dL in women and <13g/dL in men), mortality at 30 days and at 1 year, risk factors, comorbidity, functional impairment, basal functional grade for dyspnoea, chronic and acute treatment, clinical and analytical data of the episode, and patient destination. STATISTICAL ANALYSIS Bivariate analysis and survival analyses using Cox regression. RESULTS A total of 13 454 patients were included, 7662 (56.9%) of whom had anaemia. Those with anaemia were older, had more comorbidity, a worse functional status and New York Heart Association class, greater renal function impairment, and more hyponatraemia. The mortality was higher in patients with anaemia at 30 days and 1 year: 7.5% vs 10.7% (P < .001) and 21.2% vs 31.4% (P < .001), respectively. The crude and adjusted hazard ratios of anaemia for 30-day mortality were: 1.46 (confidence interval [CI] 95% 1.30-1.64); P < .001 and 1.20 (CI 95% 1.05-1.38); P = .009, respectively, and 1.57 (CI 95% 1.47-1.68) and 1.30 (CI 95% 1.20-1.40) for mortality at 1 year. The weight of anaemia on mortality was different in each follow-up period. CONCLUSIONS Anaemia is an independent predictor of mortality at 30 days and 1 year in patients with AHF attended in HEDs. It is important to study the aetiology of AHF since adequate treatment would reduce mortality.

Abstract
Large numbers of people are being discharged from hospital following COVID-19 without assessment of recovery. In 384 patients (mean age 59.9 years; 62% male) followed a median 54 days post discharge, 53% reported persistent breathlessness, 34% cough and 69% fatigue. 14.6% had depression. In those discharged with elevated biomarkers, 30.1% and 9.5% had persistently elevated d-dimer and C reactive protein, respectively. 38% of chest radiographs remained abnormal with 9% deteriorating. Systematic follow-up after hospitalisation with COVID-19 identifies the trajectory of physical and psychological symptom burden, recovery of blood biomarkers and imaging which could be used to inform the need for rehabilitation and/or further investigation.

Abstract
Human organs are complex, three-dimensional and multiscale systems. Spatially mapping the human body down through its hierarchy, from entire organs to their individual functional units and specialised cells, is a major obstacle to fully understanding health and disease. To meet this challenge, we developed hierarchical phase-contrast tomography (HiP-CT), an X-ray phase propagation technique utilising the European Synchrotron Radiation Facility's Extremely Brilliant Source: the world's first high-energy 4 th generation X-ray source. HiP-CT enabled three-dimensional and non-destructive imaging at near-micron resolution in soft tissues at one hundred thousand times the voxel size whilst maintaining the organ's structure. We applied HiP-CT to image five intact human parenchymal organs: brain, lung, heart, kidney and spleen. These were hierarchically assessed with HiP-CT, providing a structural overview of the whole organ alongside detail of the organ's individual functional units and cells. The potential applications of HiP-CT were demonstrated through quantification and morphometry of glomeruli in an intact human kidney, and identification of regional changes to the architecture of the air-tissue interface and alveolar morphology in the lung of a deceased COVID-19 patient. Overall, we show that HiP-CT is a powerful tool which can provide a comprehensive picture of structural information for whole intact human organs, encompassing precise details on functional units and their constituent cells to better understand human health and disease.

Abstract
As the coronavirus pandemic evolves, the focus of radiology departments has begun to change. The acute phase of imaging a new disease entity whilst rationalising radiology services in the face of lockdown has passed. Radiologists are now becoming familiar with the complications of COVID-19, particularly the lung parenchymal and pulmonary vascular sequelae and are considering the impact follow-up imaging may have on departments already struggling with a backlog of suspended imaging in the face of reduced capacity. This review from the British Society of Thoracic Imaging explores both the thoracic and extra-thoracic complications of COVID-19, recognising the importance of a holistic approach to patient follow-up. The British Thoracic Society guidelines for respiratory follow-up of COVID-19 will be discussed, together with newly developed reporting templates, which aim to provide consistency for clinicians as well as an opportunity for longer-term data collection.
