Abstract
Salmonella is one of the most frequent causes of diarrhea globally. This study used a One Health approach to identify Salmonella species in children admitted with diarrhea and tested samples from the cases' household environment to investigate their genetic similarity using whole genome sequencing. Surveillance of hospitalized diarrhea cases among children under 5 years was conducted in rural and urban Moshi Districts in the Kilimanjaro Region of Tanzania from July 2020 through November 2022. Household visits were conducted for every child case whose parent/caregiver provided consent. Stool samples, water, domestic animal feces, meat, and milk were collected and tested for Salmonella. Isolates were sequenced on the Illumina NextSeq platform. Multilocus Sequence Typing and phylogenetic analyses were performed to map the genetic relatedness of the isolates. Salmonella was isolated from 72 (6.0%) of 1,191 samples. The prevalence of Salmonella in children with diarrhea, domestic animal feces, food, and water was 2.6% (n = 8/306), 4.6% (n = 8/174), 4.2% (n = 16/382), and 17.3% (n = 39/225), respectively. Four (1.3%) of the 306 enrolled children had a Salmonella positive sample taken from their household. The common sequence types (STs) were ST1208, ST309, ST166, and ST473. Salmonella Newport was shared by a case and a raw milk sample taken from the same household. The study revealed a high diversity of Salmonella spp., however, we detected a Salmonella clone of ST1208 isolated at least from all types of samples. These findings contribute to understanding the epidemiology of Salmonella in the region and provide insight into potential control of foodborne diseases through a One Health approach.

Abstract
Tobacco smoking is associated with a substantially increased risk of postoperative complications. The peri-operative period offers a unique opportunity to support patients to stop tobacco smoking, avoid complications and improve long-term health. This systematic review provides an up-to-date summary of the evidence for tobacco cessation interventions in surgical patients. We conducted a systematic search of randomised controlled trials of tobacco cessation interventions in the peri-operative period. Quantitative synthesis of the abstinence outcomes data was by random-effects meta-analysis. The primary outcome of the meta-analysis was abstinence at the time of surgery, and the secondary outcome was abstinence at 12 months. Thirty-eight studies are included in the review (7310 randomised participants) and 26 studies are included in the meta-analysis (5969 randomised participants). Studies were pooled for subgroup analysis in two ways: by the timing of intervention delivery within the peri-operative period and by the intensity of the intervention protocol. We judged the quality of evidence as moderate, reflecting the degree of heterogeneity and the high risk of bias. Overall, peri-operative tobacco cessation interventions increased successful abstinence both at the time of surgery, risk ratio (95%CI) 1.48 (1.20-1.83), number needed to treat 7; and 12 months after surgery, risk ratio (95%CI) 1.62 (1.29-2.03), number needed to treat 9. More work is needed to inform the design and optimal delivery of interventions that are acceptable to patients and that can be incorporated into contemporary elective and urgent surgical pathways. Future trials should use standardised outcome measures.

Abstract
Gender-affirming care for transgender and gender diverse (TGD) individuals is a multidisciplinary endeavor that requires organized efforts of many specialized practitioners. TGD individuals experience many health care barriers, including the scarcity of multidisciplinary teams formed to coordinate and deliver complex care in an efficient and affirming way. The Johns Hopkins Center for Transgender Health was founded in 2017 with the mission of decreasing health disparities and improving the health of the TGD community. The authors present their experience building the center around a service line model in which patients have 1 point of contact, they are tracked throughout the care process, and the multidepartmental practitioners involved in their care are aligned. This model allowed for a patient-centered experience in which all involved disciplines were seamlessly integrated and the patient could navigate easily among them. With the structure and mission in place, the next challenge was to develop an infrastructure for culturally competent care. Through competency training and adjustment of systems-based logistics, measures were put in place to prevent traumatic experiences, such as misgendering, use of culturally inappropriate vocabulary, and use of incorrect names. Partnerships among colleagues in the fields of plastic surgery, urology, gynecology, otolaryngology, anesthesia, psychiatry/mental health, internal medicine, endocrinology, fertility, nursing, social work, speech therapy, and pediatrics/adolescent care were necessary to provide the appropriate breadth of services to care for TGD patients. Since its inception, the center has seen steady and continual growth, with more than 2,800 patients in its first 5 years. By sharing their experience in creating and developing a center of excellence, the authors hope to provide a blueprint for others to expand health care quality and access for TGD individuals.

Abstract
PURPOSE The purpose of this research is to develop a set of continuous glucose monitoring (CGM)-related measure concepts to be tested in a health care system. Existing measures assessing the quality of diabetes care do not include modern approaches to diabetes management, such as CGM. Continuous glucose monitors rival traditional methods of measuring diabetes management by providing real-time, longitudinal data and demonstrating glucose variability over time. The Improving Diabetes Quality Initiative seeks to address this gap in diabetes quality measurement. METHODS A Technical Expert Panel (TEP) was convened to curate a diabetes quality measures portfolio and conceptualize three new CGM-related quality measures within the portfolio. From the additional measure concepts identified in the portfolio, the TEP prioritized three for conceptualization. High-level measure concept specifications were made available during a public comment period. RESULTS The measure concepts prioritized by the TEP included a shared decision-making measure to assess the value of initiating CGM for disease management, a utilization measure to address disparities in access and use of CGM, and a patient-provider review of CGM data to promote routine consideration of these assessments in treatment and ongoing management. Clinical literature, public comments, and TEP feedback informed full measure specifications. CONCLUSIONS The evolution of diabetes technology reflects the need to shift diabetes quality of care. The measure concepts will be tested in a flexible pilot setting to understand the future of diabetes care and communicate the value of CGM to people with diabetes, providers, and payers.

Abstract
Introduction COVID-19 infection has been associated with increase arterial stiffness, endothelialdysfunction, and impairment in coronary and cardiac performance. Inflammation and oxidative stress have beensuggested as possible pathophysiological mechanisms leading to vascular and endothelial deregulation afterCOVID-19 infection. Purpose The objective of our study is to evaluate premature alterations in arterial stiffness, endothelial,coronary, and myocardial function markers four months after SARS-CoV-2 infection. Methods In a case-control prospective study, we included 70 patients 4 months after COVID-19 infection, 70 age- and sex-matched untreated hypertensive patients (positive control) and 70 healthy individuals. We measured (i) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness), (ii) flow-mediated dilatation (FMD), (iii) coronary flow reserve (CFR) by Doppler echocardiography, (iv) pulse wave velocity (PWV) and central systolic blood pressure (cSBP), (v) global left and right ventricular longitudinal strain (GLS), (vi) malondialdehyde (MDA), an oxidative stress marker, thrombomodulin and von Willebrand factor as endothelial biomarkers. Results COVID-19 patients had similar CFR and FMD with hypertensives (2.48±0.41 vs 2.58±0.88, p=0.562, 5.86±2.82% vs 5.80±2.07%, p=0.872 respectively) but lower values than controls (3.42±0.65, p=0.0135, 9.06±2.11%, p=0.002 respectively). Compared to controls, both COVID-19 and hypertensives had greater PBR5–25 (2.07±0.15μm and 2.07±0.26μm p=0.8 vs 1.89±0.17μm, p=0.001), higher PWV, (12.09±2.50 vs 11.92±2.94, p=0.7 vs 10.04±1.80m/sec, p=0.036) increased cSBP (128.43±17.39 vs 135.17±16.83 vs 117.89±18.85) and impaired LV and RV GLS (−19.50±2.56% vs −19.23±2.67%, p=0.864 vs −21.98±1.51%, p=0.020 and −16.99±3.17% vs −18.63±3.20%, p=0.002 vs −20.51±2.28%, p<0.001). MDA and thrombomodulin were higher in COVID-19 patients than both hypertensives and controls (10.67±2.75 vs 1.76±0.30, p=0.003 vs 1.01±0.50nmole/L, p=0.001 and 3716.63±188.36 vs 3114.46±179.18, p=0.017 vs 2590.02±156.51pg/ml, p<0.001). COVID-19 patients displayed similar vWF values with hypertensives but higher compared with healthy controls (4018.03±474.31 vs 3756.65±293.28 vs 2079.33±855.10 ng/ml, p=0.718 and p=0.016 respectively). Conclusions SARS-CoV-2 infection is associated with oxidative stress, endothelial and vascular dysfunction, which are linked to impaired longitudinal myocardial deformation 4 months after COVID-19 infection.

Abstract
Introduction COVID-19 patients present impaired subclinical markers of cardiovascular and endothelial function. Subclinical myocardial and vascular dysfunction during COVID-19 disease have been associated with worse outcomes and higher mortality risk. Purpose We investigated the effect of COVID-19 infection on markers of endothelial, vascular and myocardial function at four and twelve months after the infection Methods We recruited 70 patients who were examined in a dedicated post-COVID-19 outpatient clinic during a scheduled follow-up visit at four and twelve months after a confirmed COVID-19 infection and 70 healthy individuals with similar clinical characteristics. At four and twelve months we measured (i) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness), (ii) flow-mediated dilatation (FMD), (iii) coronary flow reserve (CFR) by Doppler echocardiography, (iv) pulse wave velocity (PWV) and central systolic blood pressure (cSBP), (v) global left and right ventricular longitudinal strain (GLS), (vi) myocardial global work index (GWI) global constructive work (GCW), global wasted work (GWW) and the myocardial global work efficiency (GWE) and v) malondialdehyde (MDA), an oxidative stress marker. Results At four months, COVID-19 patients displayed higher values of PBR5–25 compared to control group (p<0.001) which increased at twelve months (p<0.001). FMD, PWV and cSBP values were similar between 4 and 12 months (p>0.05 for all the comparisons) and higher than those in controls (p<0.001, p=0.057, p=0.003 respectively). At four months, COVID-19 patients presented impaired CFR and LVGLS values which were improved at twelve months (p=0.002, p=0.069 respectively), though remained impaired compared to controls (p=0.003 for all the comparisons). At four months, COVID-19 patients had impaired RVGLS values which were significantly improved at twelve months (p=0.001,) and showed no statistically significant difference compared to controls (p>0.05). COVID-19 patients at four months display higher myocardial wasted work and decreased myocardial efficiency compared to controls (p=0.01, p=0.006 respectively). There was a modest improvement in GWW and GWE at twelve months,(p=0.043, p=0.001, respectively); however, these markers remained impaired compared to controls (p>0.05). At four months, MDA was higher in COVID-19 patients compared to control group and significantly decreased at twelve months (p<0.001); however, these values remain higher than in controls (p=0.002) (Table 1). Conclusions SARS-CoV-2 causes endothelial and cardiovascular dysfunction which are partially restored at twelve months after the infection. Funding Acknowledgement Type of funding sources: None.

Abstract
Objectives The primary aim was to analyze differences in diet quality among higher plant protein (HPP) consumers vs higher animal protein consumers (HAP), with a secondary aim to explore intake of sodium, added sugar, saturated fat, whole and refined grains between the HPP group vs the HAP group. Methods Adults consuming either plant-based or animal-based diets were recruited to complete an online cross-sectional study. The Diet History Questionnaire III, a validated food frequency questionnaire, evaluated dietary intake over the past 3 months and calculated the Healthy Eating Index (HEI 2015) total and component scores. Due to 30% of the sample miss-classifying their diet type, participants were reclassified into the HAP and HPP groups using a median split value for total daily plant (29.51 g) and animal protein (28.2 g) to form two mutually exclusive groups. The primary aim was analyzed using an ANCOVA model, controlling for age and race. The secondary aim was analyzed using MANOVA to evaluate differences in consumption of sodium, added sugar, saturated fat, whole and refined grains between the HPP and HAP groups. Results The sample (n = 89) was primarily healthy, adult (29.1 ± 11.5 years) white (85.5%), and female (77.5%). HPP participants consumed on average 58.1 ± 23.2 grams of total protein with 42.7 ± 17.5 grams coming from plant sources while HAP participants consumed on average 77.7 + 36.8 grams of total protein with 53.8 ± 31.5 grams coming from animal sources. There was a significant difference in overall diet quality between the HPP group (78.5 ± 7.6) vs the HAP group (65.7 ± 12.4) after controlling for age and race (p < 0.01). HPP participants had higher (p < 0.01) intake of whole grains (1.7 ± 0.1 oz/day) than HAP consumers (1.0 ± 0.1 oz/day). HPP participants consumed less (p < 0.01) saturated fat (13.9 ± 7.1 g/day) compared to the HAP participants (20.8 ± 10.8g/day). There were no differences between groups for intake of added sugar (p = 0.10), sodium (p = 0.59), or refined grains (p = 0.13). Conclusions In this sample, HPP consumption was associated with higher overall diet quality than HAP, along with more whole grains and lower consumption of saturated fat. Work is needed in more diverse populations. Ultimately such research can inform nutrition education for people with HPP and HAP dietary patterns.

Abstract
BackgroundAAVs are a group of rheumatic diseases with excess morbidity and mortality (~3-fold higher compared to the general population). Long-term studies looking at mortality trends in contemporary patient cohorts are limited.ObjectivesTo investigate the overall long-term survival and all-cause mortality in a contemporary AAV patient cohort.MethodsMulticenter cohort study of patients registered and prospectively followed in the Greek ANCA Registry.ResultsData for 165 patients (989.38 patient-years of follow up) with a diagnosis of AAV (GPA n=95, 58%, MPA n=54, 33%, EGPA n=16, 9%) were analyzed (January 1, 1998 - January 10, 2022). 53% of patients were female, with a mean age of 65 (±16.4) years; the majority (97%) had generalized disease and were ANCA positive (76%). The mean follow-up since diagnosis was 5.9 (±5.1) years. At the end of follow-up, the overall mortality rate was 20% (33/165), whereas the cumulative mortality rates at 5 and 10 years were 24% and 26% respectively. Overall cumulative survival at 5 years was worse in patients with MPA (57%) compared to GPA (81%) and EGPA (92%), (p<0.001). There was no difference in long-term survival among those treated with different induction regimens including cyclophosphamide (CYC, n of deaths=24/83, 28.9%), rituximab (RTX, n=4/40, 10%) or the CYC+RTX combination (n=3/16, 18.7%). Furthermore, there was no difference in survival between relapsing (≥1 relapses) and non-relapsing (n=76) patients (Figure 1). Cumulative survival was worse in patients who initially presented with lung (66% vs. 90% at 5 years, p=0.007), kidney (56% vs. 96% at 5 years, p<0.001) and simultaneous lung and kidney (39% vs. 93% at 5 years, p<0.001) involvement. Among the 33 registered deaths, the most frequent causes were infections (52%), followed by cardiovascular events (24%), disease flares (14%) and malignancies (10%).Figure 1.ConclusionIn a contemporary multi-center AAV cohort, the cumulative mortality rates at 5 and 10 years were 24% and 26% respectively. Overall survival was worse in patients with MPA as well as those with combined lung and kidney involvement at baseline while there were no survival differences according to the initial induction regimen. Infection was the most common cause of death. These findings emphasize the unmet needs for better, less toxic therapies.AcknowledgementsSupported in part by the Greek Rheumatology Society and Professional Association of Rheumatologists (ERE-EPERE) and the Special Account for Research Grants (S.A.R.G.), National and Kapodistrian University of Athens, Athens, Greece (DV #12085, 12086).Disclosure of InterestsNone declared

Abstract
Objective
Sleeve gastrectomy (SG) and Roux-en-Y-gastric bypass (RYGB) are associated with long- term abnormalities, including erosive esophagitis (EE), hiatal hernia (HH), gastritis, Barrett`s esophagus and ulcers. The aim of this study is to assess the prevalence of abnormal endoscopic and histologic findings after SG and RYGB in a large cohort.
Methods
This is a retrospective analysis of 720 consecutive patients who underwent esophagogastroduodenoscopy (EGD) after primary SG or RYGB. Patients were invited for a control EGD after two years of follow-up. EGD was also performed in order to evaluate postoperative symptoms, such as nausea, vomiting or reflux. If revisional surgery was planned, an EGD was included in the prerevisional work up.
Results
304 post-SG patients (64.1% female) and 416 post-RYGB patients (85% female) were included. The mean age at the time of operation was 43.9 years (95% confidence intervals (CI) 42.5–43.3 years) for the post-SG group and 40.5 years (95% CI 39.4–41.6 years) for the post-RYGB group (p<0.001). The mean preoperative body mass index (BMI) was 44.2 kg/m2 (95%CI 43.4–44.9) and 41.1 kg/m2 (95%CI 40.7–41.5) for the post-SG and the post-RYGB group respectively (p<0.001). EE, gastritis and HH were more prevalent after SG than RYGB (38.8% vs 8.9%, 62.5% vs 27.6% and 28% vs 2.6% respectively, p<0.001). RYGB was associated with more postoperative ulcers than SG (14.4% vs 0.7%, p<0.001). The incidence of anastomotic strictures requiring anastomotic dilatation after RYGB was 4.6%. No significant difference was found in the prevalence of Barrett`s esophagus (4.3% post SG vs. 4.1 post RYGB, p=1.000) and Helicobacter pylori (3.3% post SG vs. 1.2% post RYGB, p=0.065) between the two groups.
Conclusion
SG is associated with higher rates of EE, gastritis and HH, while the prevalence of ulcers is higher post RYGB. There is a low risk of anastomotic stricture post RYGB. The incidence of Barrett`s oesophagus is low after both procedures. Routine use of EGD after bariatric surgery should be evaluated.

Abstract
BackgroundANCA associated vasculitides (AAVs) are rare, serious forms of vasculitides. There are limited data regarding the quality of life in patients with AAVs compared to other chronic inflammatory diseases.ObjectivesThe purpose of this study was to compare the quality of life between patients with AAV and those with a chronic inflammatory arthritis such as rheumatoid arthritis (RA).MethodsMulticenter, cross-sectional study of AAV and RA patients followed in three tertiary referral centers. Data from 1007 healthy controls served as historic controls.1 HRQoL was assessed with the Short Form 36 Health Survey (SF-36) which includes physical and mental component summary scores (PCS and MCS). Disease activity were assessed with the Birmingham Vasculitis Activity Score version 3 (BVAS 3, for AAVs) and the DAS28-ESR (for RA) respectively and organ damage/function with the Vasculitis Damage Index (VDI for AAVs) score and Health Assessment Questionnaire (HAQ for RA) scores, respectively.Results66 patients with AAVs (GPA 62%, MPA 29% and EGPA 9%, females 56%, mean age 63.4 years, generalized disease 74%, mean disease duration 6.2 years, remission 73%) and 71 with RA (females 56%, mean age 63.3 years, remission 72%) were included. Both AAV and RA patients had significantly lower PCS and MCS scores compared to healthy controls (p < 0.05) while RA patients had lower PCS and MCS scores compared to AAV patients (p < 0.05). According to disease activity status, there was no difference in the SF-36 scores between those with active (BVAS > 1) and inactive (BVAS < 1) AAV, except for the energy-fatigue component (55.0 ± 21.8 vs. 67.2 ± 20.7, p= 0.038) whereas patients with active RA (DAS28-ESR > 3.2) had lower scores for all SF36 components compared to those with low disease activity (DAS28-ESR < 3.2). Additionally, active RA patients had lower both PCS and MCS scores compared to active AAV patients (p < 0.05). AAV patients with increased damage scores (VDI > 3) had lower PCS score compared to those with less organ damage (VDI < 3), (33.9 ± 10.1 vs. 49.1 ± 10.2, p < 0.001) while RA patients with increased damage/poor functionality (HAQ ≥ 0.75) had lower both PCS and MCS scores compared to those with less damage (HAQ ≤ 0.63), (35.0 ± 7.2 vs. 48.4 ± 8.6, p < 0.001) and (40.5 ± 8.6 vs. 48.2 ± 7.6, p < 0.001 respectively). Compared to patients with AAV, RA patients with increased damage had lower score for the pain component compared to AAV patients (37.7 ± 28.6 vs. 61.2 ± 29.5, p= 0.024).ConclusionIn general, patients with AAV and RA, demonstrate impaired quality of life compared to healthy controls. In the AAV group, quality of life correlated more with organ damage and less with disease activity whereas in RA patients, quality of life correlated both with disease activity and damage. These data emphasize the need for more efficacious therapies for AAV patients that could prevent chronic organ damage and improve quality of life.References[1]Pappa, E., Kontodimopoulos, N. & Niakas, D.

Abstract
INTRODUCTION Bladder stones (BS) are still endemic in children in developing nations and account for a high volume of paediatric urology workload in these areas. The aim of this systematic review is to comparatively assess the benefits and risks of minimally invasive and open surgical interventions for the treatment of bladder stones in children. METHODS This systematic review was conducted in accordance with Cochrane Guidance. Database searches (January 1970- March 2021) were screened, abstracted, and assessed for risk of bias for comparative randomised controlled trials (RCTs) and non-randomised studies (NRSs) with >10 patients per group. Open cystolithotomy (CL), transurethral cystolithotripsy (TUCL), percutaneous cystolithotripsy (PCCL), extracorporeal shock wave lithotripsy (ESWL) and laparoscopic cystolithotomy (LapCL) were evaluated. RESULTS In total, 3040 abstracts were screened, and 8 studies were included. There were 7 retrospective non-randomised studies (NRS's) and 1 quasi-RCT with 1034 eligible patients (CL: n=637, TUCL: n=196, PCCL: n=138, ESWL: n=63, LapCL n=0). Stone free rate (SFR) was given in 7 studies and measured 100%, 86.6%-100%, and 100% for CL, TUCL and PCCL respectively. CL was associated with a longer duration of inpatient stay than PCCL and TUCL (p<0.05). One NRS showed that SFR was significantly lower after 1 session with outpatient ESWL (47.6%) compared to TUCL (93.5%) and CL (100%) (p<0.01 and p<0.01 respectively). One RCT compared TUCL with laser versus TUCL with pneumatic lithotripsy and found that procedure duration was shorter with laser for stones <1.5cm (n=25, p=0.04). CONCLUSION In conclusion, CL, TUCL and PCCL have comparable SFRs but ESWL is less effective for treating stones in paediatric patients. CL has the longest duration of inpatient stay. Information gathered from this systematic review will enable paediatric urologists to comparatively assess the risks and benefits of all urological modalities when considering surgical intervention for bladder stones.

Aims
SARS-CoV-2 infection may lead to endothelial and vascular dysfunction. We
investigated alterations of arterial stiffness, endothelial coronary and myocardial
function markers four months after COVID-19 infection.
Methods
In a case-control prospective study, we included 100 patients four months after COVID-19 infection, 50 age- and sex-matched healthy individuals. We measured a) pulse wave velocity (PWV), b) flow-mediated dilation (FMD) of brachial artery, c) coronary Flow Reserve (CFR) by Doppler echocardiography d) left ventricular (LV) global longitudinal strain (GLS), e) left ventricular myocardial work index, constructive work, wasted work and work efficiency and e) von-Willenbrand factor and thrombomodulin as endothelial biomarkers.
Results
COVID-19 patients had lower CFR and FMD values than controls (2.39 ± 0.39 vs 3.31 ± 0.59, p = 0.0122, 5.12 ± 2.95% vs 8.12 ± 2.23%, p = 0.006 respectively). Compared to controls, COVID-19 patients had higher PWV (PWVc-f 12.32 ± 2.44 vs 10.11 ± 1.85 m/sec, p = 0.033) and impaired LV GLS (-19.11 ± 2.14% vs -20.41 ± 1.61%, p = 0.001). Compared to controls, COVID-19 patients had higher myocardial work index, and wasted work (2067.7 ± 325.9 mmHg% vs 1929.4 ± 312.7 mmHg%, p = 0.026, 104.6 ± 58.9 mmHg% vs 75.1 ± 52.6 mmHg%, p = 0.008, respectively), while myocardial efficiency was lower (94.8 ± 2.5% vs 96.06 ± 2.3%, p = 0.008). and thrombomodulin were higher in COVID-19 patients than controls (3716.63 ± 188.36 vs 2590.02 ± 156.51pg/ml, p < 0.001). MDA was higher in COVID-19 patients than controls (10.55 ± 2.45 vs 1.01 ± 0.50 nmole/L, p = 0.001). Residual cardiovascular symptoms at 4 months were associated with oxidative stress markers. Myocardial work efficiency was related with PWV (F=-0.309, p = 0.016) and vWillenbrand (F=-0.541, p = 0.037). Myocardial wasted work was related with PWV (F = 0.255, p = 0.047) and vWillenbrand (F = 0.610, p = 0.016).
Conclusions
SARS-CoV-2 may cause vascular dysfunction, followed by a waste of cardiac work, in order to compensate for increased arterial stiffness 4 months after infection.

Abstract
OBJECTIVES Copper filtration removes lower energy X-ray photons, which do not enhance image quality but would otherwise contribute to patient radiation dose. This study explores the use of additional copper filtration for neonatal mobile chest imaging. METHODS A controlled factorial-designed experiment was used to determine the effect of independent variables on image quality and radiation dose. These variables included: copper filtration (0 Cu, 0.1 Cu and 0.2 Cu), exposure factors, source-to-image distance and image receptor position (direct / tray). Image quality was evaluated using absolute visual grading analysis (VGA) and contrast-to-noise ratio (CNR) and entrance surface dose (ESD) was derived using an ionising chamber within the central X-ray beam. RESULTS VGA, CNR and ESD significantly reduced (p < 0.01) when using added copper filtration. For 0.1 Cu, the percentage reduction was much greater for ESD (60%) than for VGA (14%) and CNR (20%), respectively. When compared to the optimal combinations of parameters for incubator imaging using no copper filtration, an increase in kV and mAs when using 0.1-mm Cu resulted in better image quality at the same radiation dose (direct) or, equal image quality at reduced dose (in-tray). The use of 0.1-mm Cu for neonatal chest imaging with a corresponding increase in kV and mAs is therefore recommended. CONCLUSION Using additional copper filtration significantly reduces radiation dose (at increased mAs) without a detrimental effect on image quality. ADVANCES IN KNOWLEDGE This is the first study, using an anthropomorphic phantom, to explore the use of additional Cu for digital radiography neonatal chest imaging and therefore helps inform practice to standardise and optimise this imaging examination.

Abstract
Carers of people with a life-limiting illness report unmet information, practical, and emotional support needs, and are often unaware of services available to help improve preparedness, wellbeing, and reduce strain. CarerHelp is the first e-health toolkit that focuses on the information and support needs of carers of people with a life-limiting illness at the end-of-life, using a pathway approach. This study investigated the usefulness of CarerHelp, from the perspective of health professionals who care for these people. Through a 10-min online survey, health professionals provided feedback about their user experience and perceived usefulness of the website. Their expert opinion was sought to ascertain whether CarerHelp could increase carers' preparedness and confidence to support the person for whom they are caring and thereby improve carers' own psychological wellbeing. Health professionals also evaluated whether CarerHelp adequately raised awareness of support services available. CarerHelp was perceived as a useful resource for increasing preparedness for the caring role, including physical tasks and emotional support. Health professionals reported that CarerHelp would increase carers' knowledge of services, confidence to care and ability for self-care. Health professionals endorsed CarerHelp as a useful information source, guide for support, and would promote CarerHelp to clients and their families.

Abstract
Background/Introduction COVID-19 infection has been associated with increase arterial stiffness, endothelial dysfunction, and impairment in coronary and cardiac performance. Inflammation and oxidative stress have been suggested as possible pathophysiological mechanisms leading to vascular and endothelial deregulation after COVID-19 infection. Purpose The objective of our study is to evaluate premature alterations in arterial stiffness, endothelial, coronary, and myocardial function markers four months after SARS-CoV-2 infection. Methods We conducted a case-control prospective study, including 70 patients four months after COVID-19 infection, 70 age- and sex-matched untreated hypertensive patients (positive control) and 70 healthy individuals. We measured a) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness b) flow-mediated dilation (FMD), c) coronary Flow Reserve (CFR) by Doppler echocardiography d) pulse wave velocity (PWV) and central systolic (SBP) e) global LV longitudinal strain (GLS) by speckle tracking imaging and f) malondialdehyde (MDA) as oxidative stress marker. Results COVID-19 patients had similar CFR and FMD with hypertensives (2.48±0.41 vs 2.58±0.88, p=0.562, 5.86±2.82% vs 5.80±2.07%, p=0.872 respectively), but lower CFR and FMD than controls (3.42±0.65, p=0.0135 9.06±2.11%, p=0.002 respectively) Both COVID-19 and hypertensive group had greater PBR than controls (PBR5–25: 2.07±0.15 μm and 2.07±0.26 μm p=0.8 vs 1.89±0.17 μm, p=0.001). COVID-19 patients and hypertensives had higher PWV and central SBP than controls (PWVcf 12.09±2.50 and 11.92±2.94, p=0.7 vs 10.04±1.80 m/sec, p=0.036). COVID-19 patients and hypertensives had impaired values of GLS compared to controls (−19.50±2.56% and −19.23±2.67%, p=0.864 vs −21.98±1.51%, p=0.020). Increased PBR5–25 was associated with increased SBP central which in turn was related with impaired GLS (p<0.05). MDA was found increased in COVID-19 patients compared to both hypertensives and controls (10.67±2.75 vs 1.76±0.30, p=0.003 vs 1.01±0.50 nmole/L, p=0.001). Conclusions SARS-CoV-2 may cause impaired coronary microcirculatory, endothelial and vascular deregulation which remain four months after initial infection and are associated with reduced cardiac performance. The 10-fold increase of MDA compared to healthy individuals four months after COVID-19 infection indicate oxidative stress as possible pathophysiological mechanism.

Abstract
Abstract
Aim
Non-muscle-invasive bladder cancer (NMIBC) is the most prevalent form of bladder cancer, predominantly affecting the elderly population. The most common treatment for recurrent NMIBC is transurethral resection of the bladder tumour (TURBT), which carries a risk of perioperative morbidity and mortality in this often-co-morbid population. Outpatient laser ablation of low-grade NMIBC recurrences is a minimally invasive treatment option, but long-term efficacy is poorly reported.
Method
We retrospectively reviewed the case notes of all patients treated with Holmium:YAG laser ablation from 2008-2016. Data regarding patient demographics, original histology, dates of procedures, follow-up time, recurrence, progression, and complications were recorded.
Results
A total of 199 procedures were performed on 97 patients (mean age of 83.56), 73 (75.3%) of which originally had low-grade (G1 or G2) tumours. Overall, 55 (56.7%) patients developed tumour recurrence at long-term follow-up (mean 5.36 years), and only 9 (9.3%) patients had tumour progression to a higher stage or grade, but there was no progression to muscle-invasive disease. The median recurrence-free, progression-free and overall survival times were 1.69 years (95% CI 1.20-2.25), 5.70 years (95% CI 4.10-7.60) and 7.60 years (95% CI 4.90-8.70), respectively. No patients required emergency inpatient admission after laser ablation for any associated complications.
Conclusions
Office-based Holmium: YAG laser ablation is an oncologically-safe method of managing recurrent low-grade non-muscle-invasive bladder cancer in the long-term, with no patients progressing to muscle-invasive disease. Furthermore, the procedure is safe, and no significant complications were seen in this elderly and co-morbid population.

Abstract
BACKGROUND CONTEXT Spine patients have a higher rate of depression then the general population which may be caused in part by levels of pain and disability from their spinal disease. PURPOSE Determination whether improvements in health-related quality of life (HRQOL) resulting from successful spine surgery leads to improvements in mental health. STUDY DESIGN/SETTING The Canadian Spine Outcome Research Network prospective surgical outcome registry. OUTCOME MEASURES Change between preoperative and postoperative SF12 Mental Component Score (MCS). Secondary outcomes include European Quality of Life (EuroQoL) Healthstate, SF-12 Physical Component Score (PCS), Oswestry Disability Index (ODI), Patient Health Questionaire-9 (PHQ9), and pain scales. METHODS The Canadian Spine Outcome Research Network registry was queried for all patients receiving surgery for degenerative thoracolumbar spine disease. Exclusion criteria were trauma, tumor, infection, and previous spine surgery. SF12 Mental Component Scores (MCS) were compared between those with and without significant improvement in postoperative disability (ODI) and secondary measures. Multivariate analysis examined factors predictive of MCS improvement. RESULTS Eighteen hospitals contributed 3222 eligible patients. Worse ODI, EuroQoL, PCS, back pain and leg pain correlated with worse MCS at all time points. Overall, patients had an improvement in MCS that occurred within 3 months of surgery and was still present 24 months after surgery. Patients exceeding Minimally Clinically Important Differences in ODI had the greatest improvements in MCS. Major depression prevalence decreased up to 48% following surgery, depending on spine diagnosis. CONCLUSIONS Large scale, real world, registry data suggests that successful surgery for degenerative lumbar disease is associated with reduction in the prevalence of major depression regardless of the specific underlaying diagnosis. Worse baseline MCS was associated with worse baseline HRQOL and improved postoperatively with coincident improvement in disability, emphasizing that mental wellness is not a static state but may improve with well-planned spine surgery.

Abstract
Purpose The life-saving role of oxygen therapy in African children with severe pneumonia is not yet established. Methods The open-label fractional-factorial COAST trial randomised eligible Ugandan and Kenyan children aged > 28 days with severe pneumonia and severe hypoxaemia stratum (SpO2 < 80%) to high-flow nasal therapy (HFNT) or low-flow oxygen (LFO: standard care) and hypoxaemia stratum (SpO2 80–91%) to HFNT or LFO (liberal strategies) or permissive hypoxaemia (ratio 1:1:2). Children with cyanotic heart disease, chronic lung disease or > 3 h receipt of oxygen were excluded. The primary endpoint was 48 h mortality; secondary endpoints included mortality or neurocognitive sequelae at 28 days. Results The trial was stopped early after enrolling 1852/4200 children, including 388 in the severe hypoxaemia stratum (median 7 months; median SpO2 75%) randomised to HFNT (n = 194) or LFO (n = 194) and 1454 in the hypoxaemia stratum (median 9 months; median SpO2 88%) randomised to HFNT (n = 363) vs LFO (n = 364) vs permissive hypoxaemia (n = 727). Per-protocol 15% of patients in the permissive hypoxaemia group received oxygen (when SpO2 < 80%). In the severe hypoxaemia stratum, 48-h mortality was 9.3% for HFNT vs. 13.4% for LFO groups. In the hypoxaemia stratum, 48-h mortality was 1.1% for HFNT vs. 2.5% LFO and 1.4% for permissive hypoxaemia. In the hypoxaemia stratum, adjusted odds ratio for 48-h mortality in liberal vs permissive comparison was 1.16 (0.49–2.74; p = 0.73); HFNT vs LFO comparison was 0.60 (0.33–1.06; p = 0.08). Strata-specific 28 day mortality rates were, respectively: 18.6, 23.4 and 3.3, 4.1, 3.9%. Neurocognitive sequelae were rare. Conclusions Respiratory support with HFNT showing potential benefit should prompt further trials.

Abstract
Abstract
Introduction: Adrenal Venous Sampling (AVS) is the most reliable means of identifying surgically curable subtypes of primary aldosteronism (PA). Cortisol levels are used to determine cannulation success and lateralization. However, cortisol has a variable secretion pattern and long-half life, and can be co-secreted by adrenal adenomas, leading to misinterpretation of results. Plasma metanephrines (MN) are a possible alternative analyte. MN levels are unaffected by stress, have a short half-life of 3–6 minutes and are released continuously by the adrenals, resulting in very high concentration gradients between the adrenal veins (AV) and peripheral veins (PV), thus providing a sensitive means to determine cannulation success. Premise:The objective of this study was to see if MN can be used in lieu of cortisol in AVS. A secondary end-point was to see if the data was particularly useful in patients who are known co-secretors of cortisol. Methods: Data from AVS carried out without cosyntropin stimulation, from October 2018 to March 2020, were analysed retrospectively. Of these, 51 had additional samples drawn for MN at the time of the procedure and were recruited. Six patients were identified as having autonomous cortisol secretion as they failed an overnight dexamethasone suppression test (ONDST). The data was analysed using cortisol and MN separately and then compared with regards to their selectivity and lateralization index. Data was also analysed to see if known co-secretors had an elevated cortisol/MN ratio of more than 2 on the affected side as described in previous papers. Results: When compared to cannulation and lateralization outcomes using cortisol, similar results were obtained using, a MN AV/PV ratio of more than 12 to indicate successful cannulation and an aldosterone/MN ratios of greater than 5 to confirm lateralization. Contralateral suppression to less than 0.5 for aldosterone/MN below the PV was seen in unilateral disease. With regards to the six co-secretors, all had elevated cortisol/MN ratios of more than 2 on the affected side. Three had concordant results but the other three had discrepant results, with MN analysis suggesting unilateral disease and cortisol measurements suggesting bilateral disease. Two had undergone surgery with biopsy confirming unilateral disease that correlated with MN analysis. The third is under medical management. Conclusion: This is the first study evaluating the use of MN to determine lateralisation of aldosterone production in PA. Further studies are needed, but using MN may be a more reliable alternative to cortisol in the analysis of AVS before definitive surgery in particular in patients with cortisol co-secretion.

Abstract
Reduction in unwanted facial and body hair is an important goal in the process of sex reassignment. Laser treatment is a popular, well-established safe and effective method of reducing unwanted hair growth. In the UK a limited number of laser treatment and electrolysis sessions are publically funded for people undergoing sex reassignment. To date, published evidence on efficacy and adverse effects (AEs) has focused on treatment of women and men not undergoing sex reassignment. In the current study, data were collected prospectively from 2015 to 2020 at a UK regional laser centre. Patients were included if they were transgender women aged > 16 years old and seeking laser treatment for unwanted hair at any body site. The study demonstrated significant reductions in hair growth and significant patient satisfaction, with no AEs. Laser treatment is a safe and effective method of managing unwanted hair growth in the transgender transfeminine population.

Abstract
OBJECTIVE The knee adduction moment (KAM) can inform treatment of medial knee osteoarthritis; however, measuring the KAM requires an expensive gait analysis laboratory. We evaluated the feasibility of predicting the peak KAM during natural and modified walking patterns using the positions of anatomical landmarks that could be identified from video analysis. METHOD Using inverse dynamics, we calculated the KAM for 86 individuals (64 with knee osteoarthritis, 22 without) walking naturally and with foot progression angle modifications. We trained a neural network to predict the peak KAM using the 3-dimensional positions of 13 anatomical landmarks measured with motion capture (3D neural network). We also trained models to predict the peak KAM using 2-dimensional subsets of the dataset to simulate 2-dimensional video analysis (frontal and sagittal plane neural networks). Model performance was evaluated on a held-out, 8-person test set that included steps from all trials. RESULTS The 3D neural network predicted the peak KAM for all test steps with r2( Murray et al., 2012) 2 = 0.78. This model predicted individuals' average peak KAM during natural walking with r2( Murray et al., 2012) 2 = 0.86 and classified which 15° foot progression angle modifications reduced the peak KAM with accuracy = 0.85. The frontal plane neural network predicted peak KAM with similar accuracy (r2( Murray et al., 2012) 2 = 0.85) to the 3D neural network, but the sagittal plane neural network did not (r2( Murray et al., 2012) 2 = 0.14). CONCLUSION Using the positions of anatomical landmarks from motion capture, a neural network accurately predicted the peak KAM during natural and modified walking. This study demonstrates the feasibility of measuring the peak KAM using positions obtainable from 2D video analysis.

The aim of this study was to evaluate the diagnostic accuracy of six LN characteristics on CT in detecting melanoma-positive ilioinguinal LN metastases, and to determine whether inguinal LN characteristics can predict pelvic LN involvement. Methods This was a single-centre retrospective study of patients with melanoma LN metastases at a tertiary cancer centre between 2008 and 2016. Patients who had preoperative contrast-enhanced CT assessment and ilioinguinal LN dissection were included. CT scans containing significant artefacts obscuring the pelvis were excluded. CT scans were reanalysed for six LN characteristics (extracapsular spread (ECS), minimum axis (MA), absence of fatty hilum (FH), asymmetrical cortical nodule (CAN), abnormal contrast enhancement (ACE) and rounded morphology (RM)) and compared with postoperative histopathological findings. Results A total of 90 patients were included. Median age was 58 (range 23–85) years. Eighty-eight patients (98 per cent) had pathology-positive inguinal disease and, of these, 45 (51 per cent) had concurrent pelvic disease. The most common CT characteristics found in pathology-positive inguinal LNs were MA greater than 10 mm (97 per cent), ACE (80 per cent), ECS (38 per cent) and absence of RM (38 per cent). In multivariable analysis, inguinal LN characteristics on CT indicative of pelvic disease were RM (odds ratio (OR) 3.3, 95 per cent c.i. 1.2 to 8.7) and ECS (OR 4.2, 1.6 to 11.3). Cloquet’s node is known to be a poor predictor of pelvic spread. Pelvic LN disease was present in 50 per cent patients, but only 7 per cent had a pathology-positive Cloquet’s node. Conclusion Additional CT radiological characteristics, especially ECS and RM, may improve diagnostic accuracy and aid clinical decisions regarding the need for inguinal or ilioinguinal dissection.

Abstract
Mutagenic compounds are a potent source of human disease. By inducing genetic instability, they can accelerate the evolution of human cancers or lead to the development of genetically inherited diseases. Here, we show that in addition to genetic mutations, mutagens are also a powerful source of transcription errors. These errors arise in dividing and nondividing cells alike, affect every class of transcripts inside cells, and, in certain cases, greatly exceed the number of mutations that arise in the genome. In addition, we reveal the kinetics of transcription errors in response to mutagen exposure and find that DNA repair is required to mitigate transcriptional mutagenesis after exposure. Together, these observations have far-reaching consequences for our understanding of mutagenesis in human aging and disease, and suggest that the impact of DNA damage on human physiology has been greatly underestimated.

Abstract
A 49-year old male with a past medical history of myocardial infarction and compartment syndromes requiring fasciotomies presented on five occasions with hypovolemic shock. We describe his admissions and presumptive diagnoses which required large volumes of intravenous fluids, admission to intensive care for vasopressors and renal replacement therapy. The presentations were always precipitated by a prodrome of fatigue and pre-syncopal episodes. On his last admission, a diagnosis of Idiopathic systemic capillary leak syndrome (ISCLS), also known as Clarkson's Disease, was reached. He is currently receiving high dose intravenous immunoglobulins on a monthly basis.

Abstract
Children with ASD and an IQ-matched control group of typically developing (TD) children completed an elicited-production task which encouraged the production of reversible passive sentences (e.g., "Bob was hit by Wendy"). Although the two groups showed similar levels of correct production, the ASD group produced a significantly greater number of "reversal" errors (e.g., "Wendy was hit by Bob", when, in fact Wendy hit Bob) than the TD group (who, when they did not produce correct passives, instead generally produced semantically appropriate actives; e.g., "Wendy hit Bob"). These findings suggest that the more formal elements of syntax are spared relative to more semantic/pragmatic/narrative aspects (e.g., manipulating thematic roles) in at least high-functioning children with ASD.

Abstract
BACKGROUND/INTRODUCTION The coronavirus disease 2019 (COVID-19) pandemic has affected all aspects of inpatient hospital medicine with patients admitted from level 1 (general medical wards) to level 3 (intensive care). Often, there are subtle physiological differences in these cohorts of patients. In particular, in intensive care, patients tend to be younger and have increased disease severity. Data, to date, has combined outcomes from medical and intensive care cohorts, or looked exclusively at intensive care. We looked solely at the level 1 (medical) cohort to identify their clinical characteristics and predictors of outcome. PATIENTS AND METHODS This was a retrospective study of adult patients admitted to a central London teaching hospital with a diagnosis of COVID-19 from 23rd March to 7th April 2020 identified from the hospital electronic database. Any patients who required level 2 or 3 care were excluded. RESULTS A total of 229 patients were included for analysis. Increased age and frailty scores were associated with increased 30-day mortality. Reduced renal function and elevated troponin blood levels are also associated with poor outcome. Baseline observations showed that increased oxygen requirement was predictive for mortality. A trend of increased mortality with lower diastolic blood pressure was noted. Lymphopenia was not shown to be related to mortality. CONCLUSION Urea and creatinine are the best predictors of mortality in the level 1 cohort. Unlike previous intensive care data, lymphopenia is not predictive of mortality. We suggest that these factors be considered when prognosticating and for resource allocation for the treatment and escalation of care for patients with COVID-19 infection.

Abstract
Many studies have implicated the basal forebrain (BF) as a potent regulator of sensory encoding even at the earliest stages of or cortical processing. The source of this regulation involves the well-documented corticopetal cholinergic projections from BF to primary cortical areas. However, the BF also projects to subcortical structures, including the thalamic reticular nucleus (TRN), which has abundant reciprocal connections with sensory thalamus. Here we present naturalistic auditory stimuli to the anesthetized rat while making simultaneous single-unit recordings from the ventral medial geniculate nucleus (MGN) and primary auditory cortex (A1) during electrical stimulation of the BF. Like primary visual cortex, we find that BF stimulation increases the trial-to-trial reliability of A1 neurons, and we relate these results to change in the response properties of MGN neurons. We discuss several lines of evidence that implicate the BF to thalamus pathway in the manifestation of BF-induced changes to cortical sensory processing and support our conclusions with supplementary TRN recordings, as well as studies in awake animals showing a strong relationship between endogenous BF activity and A1 reliability. Our findings suggest that the BF subcortical projections that modulate MGN play an important role in auditory processing.

Abstract
Background:Targets of therapy and quality of care are receiving increased attention in the management of SLE, as outlined in the 2019 update of the EULAR recommendations for SLE treatment.Objectives:To assess compliance with quality indicators and attainment of treatment targets, according to recent EULAR recommendations, in the SLE cohort of “Attikon” Rheumatology Unit.Methods:100 consecutive SLE patients followed for at least one year were. A 30 item Quality Indicator Set (QIS) was developed, according to the 2019 EULAR recommendations for SLE, to include laboratory tests for diagnosis and monitoring, evaluation of disease activity and damage using validated indices, use of patient-reported outcomes, counselling for women’s health and reproduction issues, attainment of targets of therapy [remission or low disease activity state (LLDAS) with low-dose glucocorticoids (GC, ≤7.5mg/day prednizone) and hydroxychloroquine (HCQ dose≤5mg/kg/day)], prevention of disease flares and prevention and management of co-morbidities. Chart review and patient interview was performed to assess the degree of compliance with each item of the QIS and achievement of treatment targets.Results:Disease activity was monitored by means of validated indices in 31% and antiphospholipid antibody testing during the first 6 months from diagnosis was performed in 58.8% of patients. Sustained remission (defined as remission of a sustained period of 12 months) or LLDAS was achieved by only 3% and 22% respectively; in contrast, other targets of therapy, such as ≤1 minor flares during last year, were achieved by 85% (43% had complete absence of flares), with 90.2% of patients receiving low-dose GC and 81.8% corrected HCQ dose. Fertility and pregnancy counselling were offered in 40% (12/30 eligible women) and 63.3% (19/30) of patients, respectively, while 65.4% had a Pap Test and only 3 of 32 eligible patients had received the HPV vaccine. Annual lipid status was assessed in 43% and counselling for smoking cessation in 44.6%. Flu vaccination was performed in 77%, while pneumococcal (including both of the pneumococcal vaccines) and herpes-zoster vaccination, were given in 32.7% and 2% (1/44 eligible patients) respectively.Conclusion:Our real-life data suggest low vaccination rates (excluding flu) and suboptimal management of cardiovascular risk factors in lupus patients. While the majority of patients received the suggested doses of GC and HCQ, only one quarter of patients achieved remission or LLDAS. There is an unmet need for new therapies in SLE to improve therapy targets.References:[1]Arora S, Sequeira W, Yazdany J, Jolly M, “Does Systemic Lupus Erythematosus Care Provided in a Lupus Clinic Result in Higher Quality of Care Than That Provided in a General Rheumatology Clinic?”, Arthritis Care Res. 2018 Dec;70(12):1771-1777. doi: 10.1002/acr.23569.

Abstract
Background:Despite the increased incidence of influenza infection in rheumatoid arthritis (RA) patients, vaccination coverage has been shown to be suboptimal. Prospective data regarding the current rate and predictors of influenza vaccination adherence in RA patients are limited.Objectives:To calculate the current rate and predictors of influenza vaccination in a real-life, prospective, longitudinal RA cohort.Methods:Data regarding demographics, disease characteristics, treatments and co-morbidities from a multi-center, longitudinal cohort of Greek RA patients were collected at baseline and ~ 3 years later. Disease and patient characteristics were compared between patients with at least one influenza vaccine administration and non-vaccinated ones, during the 3 year follow-up period.Results:From a cohort of 1,569 RA patients, 1,406 with available vaccination data at baseline and 3 years later (mean interval: 2.9 years) were included; (women: 80.4%, mean age: 61.8 years, mean disease duration: 9.7 years, RF and/or anti-CCP positive: 50.4%, mean DAS-28 = 3.33, mean HAQ: 0.44, bDMARD use: 44.8%). At baseline, 54.2% of patients reported influenza vaccination in the past (31.8% during the previous season), while during the 3 year follow-up period, 81% had ≥1 influenza vaccinations (p=<0.001). Patients who received ≥1 influenza vaccine were older (63.5 vs. 54.7 years, p<0.001), were more likely to be seropositive (59.2% vs. 45.2%, p<0.001), had higher HAQ (0.46 vs. 0.36, p=0.02) and BMI (27.7 vs. 26.9, p=0.02) at baseline, more likely to be treated with bDMARDs (46.8% vs. 36.4%, p<0.001) and more likely to have chronic lung disease (9.7% vs. 5.3%, p=0.02), dyslipidemia (36.4% vs. 24.2%, p<0.001), hypertension (46.1% vs. 29.2%, p<0.001) and to report vaccination against influenza the previous season before baseline evaluation (34.9% vs. 18.2%, p<0.001). By multivariate analysis, history of influenza vaccination during the last season before baseline (OR=1.87, CI: 1.27-2.74, p=0.001), bDMARD treatment (OR=1.51, CI: 1.07-2.13, p=0.018) and age (OR=1.05, CI: 1.04-1.06, p<0.001) were independent predictors of influenza vaccination.Conclusion:In this ongoing, longitudinal, prospective, real-life RA cohort study, a significant increase in the influenza vaccination coverage was noted (from 53% to 81%). Influenza vaccination was independently associated with recent history of influenza vaccination, older age, and bDMARD treatment.Acknowledgments:Supported by grants from the Greek Rheumatology Society and Professional Association of Rheumatologists.Disclosure of Interests:Konstantinos Thomas: None declared, Argyro Lazarini: None declared, Evripidis Kaltsonoudis: None declared, Alexandros Drosos: None declared, ARGYRO REPA: None declared, Prodromos Sidiropoulos: None declared, Kalliopi Fragkiadaki: None declared, Maria Tektonidou Grant/research support from: AbbVie, MSD, Novartis and Pfizer, Consultant of: AbbVie, MSD, Novartis and Pfizer, Petros Sfikakis Grant/research support from: Grant/research support from Abvie, Novartis, MSD, Actelion, Amgen, Pfizer, Janssen Pharmaceutical, UCB, Panagiota Tsatsani: None declared, Sousana Gazi: None declared, Pelagia Katsimbri: None declared, Dimitrios Boumpas: None declared, Evangelia Argyriou: None declared, Kyriaki Boki: None declared, Gerasimos Evangelatos: None declared, Alexios Iliopoulos: None declared, Konstantina Karagianni: None declared, Lazaros Sakkas: None declared, Konstantinos Melissaropoulos: None declared, Panagiotis Georgiou: None declared, Eleftheria Grika: None declared, PANAYIOTIS VLACHOYIANNOPOULOS: None declared, Theodoros Dimitroulas: None declared, Alexandros Garyfallos Grant/research support from: MSD, Aenorasis SA, Speakers bureau: MSD, Novartis, gsk, Constantinos Georganas: None declared, Periklis Vounotrypidis: None declared, Konstantinos Ntelis: None declared, Maria Areti: None declared, George D Kitas: None declared, Dimitrios Vassilopoulos: None declared

Abstract
Background:Previous studies have shown that withdrawing tumour necrosis factor inhibitors (TNFi) in patients (pts) with axial spondyloarthritis (axSpA) who have achieved sustained remission often leads to relapse.1However, none have formally tested TNFi dose reduction strategies in a broad axSpA population or evaluated whether relapse following TNFi dose reduction and withdrawal is associated with a specific demographic subgroup.Objectives:C-OPTIMISE evaluated the percentage of pts without flare after TNFi dose continuation, reduction or withdrawal in adults with early axSpA treated with the Fc-free, PEGylated TNFi certolizumab pegol (CZP). Here, we analyse whether responses to reduced maintenance dose were comparable in pts stratified by axSpA subpopulation, gender and age.Methods:C-OPTIMISE (NCT02505542) was a multicentre, two-part phase 3b study in adults with early (<5 years’ symptom duration) active axSpA (stratified for radiographic [r]- and non-radiographic [nr]- axSpA). Pts received CZP 200 mg every 2 weeks (wks) (Q2W; 400 mg loading dose at Wks 0, 2 and 4) during the open-label induction period. At Wk 48, pts in sustained remission (Ankylosing Spondylitis Disease Activity Score [ASDAS] <1.3 at Wk 32 or 36 [if ASDAS <1.3 at Wk 32, it must be <2.1 at Wk 36, or vice versa] and at Wk 48) were randomised to double-blind full maintenance dose (CZP 200 mg Q2W); reduced maintenance dose (CZP 200 mg every 4 wks [Q4W]) or placebo (PBO) for a further 48 wks (maintenance period). The primary endpoint was the percentage of pts not experiencing a flare (ASDAS ≥2.1 at two consecutive visits or ASDAS >3.5 at any timepoint) during Wks 48–96. Analyses were conducted on subgroups according to axSpA subpopulation, gender and age ≤/> the median age of the randomised set (32 years).Results:During the 48-wk induction period, 43.9% of patients (323/736) achieved sustained remission and 313 pts entered the 48-wk maintenance period (r/nr-axSpA: 168/145 pts; males/females: 247/66 pts; age ≤32/>32: 165/148 pts). During the maintenance period, responses in r- and nr-axSpA pts were comparable across all three randomised arms. 83.9% r-axSpA and 83.3% nr-axSpA pts receiving the full CZP maintenance dose did not experience a flare, and in the reduced maintenance dose arm 82.1% r-axSpA and 75.5% nr-axSpA pts did not experience a flare. In the PBO group this was reduced to 17.9% and 22.9%, respectively. Similar responses were seen in pts stratified by gender or age, with substantially higher percentages of pts randomised to CZP full or reduced maintenance dose remaining free of flares compared to PBO in all subgroups (Figure).Conclusion:The results of C-OPTIMISE indicate that a reduced maintenance dose is suitable for pts with axSpA who achieve sustained remission following 1 year of CZP treatment, regardless of axSpA subpopulation, gender or age. Complete treatment withdrawal is not recommended due to the high risk of flare.References:[1]Landewe R. Lancet 2018;392:134–44.Acknowledgments:This study was funded by UCB Pharma.

Abstract
Background:Comorbidities in rheumatic diseases (RDs) have been associated with increased morbidity and mortality. Evidence on prevalence of comorbidities in antiphospholipid syndrome (APS) and its difference from high comorbidity burden RDs is limited.Objectives:To compare the prevalence of common comorbidities between APS [primary (PAPS) and Systemic lupus erythematosus (SLE)-APS] and Rheumatoid arthritis (RA) patients.Methods:326 APS patients from the Greek registry (237 women, mean age 48.7±13.4 years, 161 PAPS) were matched 1:2 for age and sex with 652 RA patients from Greek RA Registry. Prevalence of cardiovascular (CV) risk factors, stroke, coronary artery disease (CAD), osteoporosis, diabetes mellitus (DM), Chronic obstructive pulmonary disease (COPD), depression and neoplasms were compared between APS and RA using logistic regression analysis.Results:Regarding CV burden, hyperlipidemia and obesity (ΒMI≥30) were comparable while hypertension, smoking, CAD and stroke were more prevalent in APS compared to RA patients (Table 1). Osteoporosis and depression were more frequent in APS while DM, COPD and neoplasms were comparable between two groups. Comparison of APS subgroups to 1:2 matched RA patients revealed that smoking and stroke were more prevalent in PAPS and SLE-APS vs RA. Hypertension, CAD and osteoporosis were more prevalent only in SLE-APS vs. RA while DM was less prevalent in PAPS vs. RA patients.Table 1.Comparison of comorbidities between Antiphospholipid syndrome (APS) vs. matched Rheumatoid Arthritis (RA) patients and between primary APS (PAPS) or Systemic Lupus Erythematosus-APS (SLE-APS) vs matched RA patientsAPSRAOR*PAPSRAORSLE-APSRAORn (%)326652161322165330Hypertension97 (29.8)136 (21)1.61 (1.19-2.18)40 (25)75 (23.3)1.09 (0.70-1.69)57 (34.6)61 (18.5)2.33 (1.52-3.56)Smoking175 (53.7)264 (40.5)1.70 (1.30-2.22)87 (54)142 (44)1.49 (1.02-2.18)88 (53.3)122 (37)1.95 (1.33-2.85)Hyperlipidemia79 (24.2)135 (20.7)1.23 (0.89-1.68)40 (24.8)62 (19.3)1.39 (0.88-2.18)39 (23.6)73 (22)1.09 (0.70-1.70)Obesity48 (20.5)105 (19.5)1.06 (0.73-1.56)20 (17)51 (19)0.86 (0.49-1.52)28 (24)54 (19.7)1.28 (0.76-2.15)Stroke±66 (20.3)9 (1.4)13.8 (6.5-29.1)36 (22.4)4 (1.2)19.9 (6.6-59.9)30 (18.2)5 (1.5)7.8 (2.7-22.6)Coronary disease±16 (4.9)13 (2)3.14 (1.17-8.45)2 (1.2)7 (2.2)0.46 (0.04-4.77)14 (8.5)6 (1.8)10.9 (2.7-44.3)Osteoporosis×66 (20.3)92 (14)1.45 (1.01-2.06)19 (11.8)42 (13)0.96 (0.54-1.73)47 (28.5)50 (15)1.91 (1.20-3.05)Diabetes×18 (5.5)58 (9)0.58 (0.33-1.01)5 (3)29 (9)0.34 (0.13-0.89)13 (8)29 (9)0.88 (0.44-1.79)COPD≠11 (3.4)14 (2.2)1.26 (0.56-2.84)3 (1.9)6 (2)0.96 (0.23-4.0)8 (5)8 (2.4)1.28 (0.44-3.72)Depression#53 (16.3)66 (10)1.70 (1.15-2.53)23 (14)30 (9.3)1.69 (0.93-3.05)30 (18.2)36 (10.9)1.65 (0.96-2.84)Neoplasms˅14 (4.3)27 (4.1)1.05 (0.54-2.06)5 (3)12 (3.7)0.84 (0.28-2.52)9 (5.5)15 (4.6)1.31 (0.55-3.1)*OR: Odds ratio, crude or adjusted for: ± age, sex, smoking, hypertension, hyperlipidemia, BMI, corticosteroid (Cs) duration × Cs duration ≠ smoking, Cs duration #sex, disease duration, Cs duration ˅ age, disease durationConclusion:Comorbidity burden in APS (PAPS and SLE-APS) is comparable or even higher to that in RA, entailing a high level of diligence for CV risk prevention, awareness for depression and corticosteroid exposure minimization.Disclosure of Interests:Stylianos Panopoulos: None declared, Konstantinos Thomas: None declared, Georgios Georgiopoulos: None declared, Dimitrios Boumpas Grant/research support from: Unrestricted grant support from various pharmaceutical companies, Christina Katsiari: None declared, George Bertsias Grant/research support from: GSK, Consultant of: Novartis, Alexandros Drosos: None declared, Kyriaki Boki: None declared, Theodoros Dimitroulas: None declared, Alexandros Garyfallos Grant/research support from: MSD, Aenorasis SA, Speakers bureau: MSD, Novartis, gsk, Charalambos Papagoras: None declared, PELAGIA KATSIMPRI: None declared, Apostolos Tziortziotis: None declared, Christina Adamichou: None declared, Evripidis Kaltsonoudis: None declared, Evangelia Argyriou: None declared, GEORGIOS VOSVOTEKAS Grant/research support from: MSD, Janssen, Consultant of: MSD, Novartis, Roche, UCB pharma, Bristol-Myers Squibb, AbbVie, Speakers bureau: UCB pharma, Menarini, Bristol-Myers Squibb, MSD, Petros Sfikakis Grant/research support from: Grant/research support from Abvie, Novartis, MSD, Actelion, Amgen, Pfizer, Janssen Pharmaceutical, UCB, Dimitrios Vassilopoulos: None declared, Maria Tektonidou Grant/research support from: AbbVie, MSD, Novartis and Pfizer, Consultant of: AbbVie, MSD, Novartis and Pfizer

Abstract
Background:Interstitial pneumonia with autoimmune features (IPAF)1describes a group of patients with interstitial lung disease and autoimmune features who do not meet the classification criteria for a specific connective tissue disease. Limited data regarding IPAF are available so far.Objectives:To identify the epidemiological and clinical characteristics of patients with IPAF and to observe disease progression, response to treatment and frequency of infections in 1-year follow-up period.Methods:Thirty-nine patients from ‘Attikon’ University Hospital of Athens fulfilling the IPAF criteria were enrolled. Clinical and laboratory findings, comorbidities, medications, pulmonary outcomes assessed with repeated pulmonary function tests (PFTs) and chest HRCT and complications in a 1-year follow-up period were documented for each patient. Univariate models were performed in order to identify determinants of infection and clinically significant difference in PFTs (defined as change of ≥ 10% in FVC and/or ≥ 15% in DLCO).Results:The mean age at the time of IPAF diagnosis was 63.2 (±11) years and 62% of the patients were female. The most common clinical features included in the IPAF criteria were arthritis (82%) and Raynaud’s phenomenon (26%). A morbilliform and/or polymorphic rash of the face, neck and extremities (not included in the IPAF criteria) was noted in 54% of patients. ANA (59%) and anti–Ro (21%) were the most common auto-antibodies. Non-specific Interstitial Pneumonia (NSIP) was the most prevalent radiological pattern (61.5%) as shown in table 1. Treatment comprised corticosteroids and immunosuppressants including hydroxychloroquine, methotrexate, azathioprine, mycophenolate and cyclophosphamide. PFTs following treatment at 6 and 12 months from baseline showed a trend of improvement (Table 2, p> 0.05). At 1 year from baseline, 20.5% of patients showed a clinically significant deterioration while 25% had a clinically significant improvement. Infections were observed in 23.1% of patients during the first semester and in 12.8% during the second semester of the follow-up period. All were respiratory tract infections and two patients (5.1%) required hospitalization. All infections occurred in patients with non-UIP pattern (p=0.02) which might be attributed to higher doses of corticosteroids used in these patients (mean initial prednisolone dose = 27 (±18) mg/d in patients with non-UIP pattern versus 17 (±16) mg/d in patients with UIP pattern, p=0.4).Table 1.Prevalence of HRCT patterns in 39 patients.Radiological patternNo (%)NSIP24 (61,5%)OP2 (5,1%)NSIP with OP overlap2 (5,1%)LIP1 (2,6%)UIP7 (18%)NSIP and UIP3 (7,7%)NSIP: Non-specific Interstitial Pneumonia, OP: Organizing Pneumonia, LIP: Lymphocytic Interstitial Pneumonia, UIP: Usual Interstitial Pneumonia.Table 2.PFTs at baseline, 6 and 12 months.PFTs (% of predicted value ± SD)Baseline6 months12 monthsP valueFVC79% (±19%)82% (±18%)84% (±17%)nsDLCO49% (±16%)52% (±17%)53% (±17%)nsConclusion:Rash is a common feature in IPAF and may be considered for inclusion into IPAF criteria. A trend of improvement in PFTs and a significant risk of respiratory tract infections mainly in the first semester of treatment and in patients with non-UIP radiological pattern were observed. Larger prospective studies are warranted in order to elucidate IPAF’s prognosis and to identify effective management approaches.References:[1]Fischer A, et al.

Abstract
BACKGROUND European data indicate that systemic sclerosis (SSc)-related death rates are increasing, thus raising concerns about SSc's optimal management. Herein, we describe current treatment modalities and drug survival in a real-life SSc cohort. METHODS Details on immunosuppressive/antiproliferative (methotrexate, mycophenolate, cyclophosphamide, azathioprine, rituximab, tocilizumab) and vasoactive agent [(endothelin receptor antagonists (ERAs), sildenafil, iloprost, and calcium channel blockers (CCB)] administration during the disease course (11.8 ± 8.4 years, mean + SD) of 497 consecutive patients examined between 2016 and 2018 were retrospectively recorded. Drug survival was assessed by Kaplan-Meier analysis. RESULTS Methotrexate was the most frequently administered immunosuppressive/antiproliferative agent (53% of patients), followed by cyclophosphamide (26%), mycophenolate (12%), and azathioprine (11%). Regarding vasoactive agents, CCB had been ever administered in 68%, ERAs in 38%, iloprost in 7%, and sildenafil in 7% of patients; 23% of patients with pulmonary fibrosis had never received immunosuppressive/antiproliferative agents, 33% of those with digital ulcers had never received ERAs, iloprost, or sildenafil, whereas 19% of all patients had never received either immunosuppressive/antiproliferative or other than CCB vasoactive agents. Survival rates of methotrexate, cyclophosphamide, and mycophenolate differed significantly, being 84/75%, 59/43%, and 74/63% at 12/24 months, respectively, with inefficacy being the most frequent discontinuation cause. Conversely, CCB, ERAs, and sildenafil had high and comparable retention rates of 97/91%, 88/86%, and 80/80%, respectively. CONCLUSIONS Existing therapeutic limitations indicate that more evidence-based treatment is warranted for successful management of SSc. Vasculopathy seems to be managed more rigorously, but the low retention rates of immunosuppressive/antiproliferative drugs suggest that effective and targeted disease-modifying agents are warranted.
