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
Brewery spent grain (BSG) has previously been exploited in bioremediation. However, detailed knowledge of the associated bacterial community dynamics and changes in relevant metabolites and genes over time is limited. This study investigated the bioremediation of diesel contaminated soil amended with BSG. We observed complete degradation of three total petroleum hydrocarbon (TPH C10-C28) fractions in amended treatments as compared to one fraction in the unamended, natural attenuation treatments. The biodegradation rate constant (k) was higher in amended treatments (0.1021k) than in unamended (0.059k), and bacterial colony forming units increased significantly in amended treatments. The degradation compounds observed fitted into the elucidated diesel degradation pathways and quantitative PCR results showed that the gene copy numbers of all three associated degradation genes, alkB, catA and xylE, were significantly higher in amended treatments. High-throughput sequencing of 16S rRNA gene amplicons showed that amendment with BSG enriched autochthonous hydrocarbon degraders. Also, community shifts of the genera Acinetobacter and Pseudomonas correlated with the abundance of catabolic genes and degradation compounds observed. This study showed that these two genera are present in BSG and thus may be associated with the enhanced biodegradation observed in amended treatments. The results suggest that the combined evaluation of TPH, microbiological, metabolite and genetic analysis provides a useful holistic approach to assessing bioremediation.

Abstract
Nanocrystalline and nanotwinned materials achieve exceptional strengths through small grain sizes. Due to large areas of crystal interfaces, they are highly susceptible to grain growth and creep deformation, even at ambient temperatures. Here, ultrahigh strength nanotwinned copper microstructures have been stabilized against high temperature exposure while largely retaining electrical conductivity. By incorporating less than 1 vol% insoluble tungsten nanoparticles by a novel hybrid deposition method, both the ease of formation and the high temperature stability of nanotwins are dramatically enhanced up to at least 400 °C. By avoiding grain coarsening, improved high temperature creep properties arise as the coherent twin boundaries are poor diffusion paths, while some size-based nanotwin strengthening is retained. Such microstructures hold promise for more robust microchip interconnects and stronger electric motor components.

Abstract
PURPOSE Sonodynamic therapy (SDT) is emerging as a cancer treatment alternative with significant advantages over conventional therapies, including its minimally invasive and site-specific nature, its radical antitumour efficacy with minimal side effects, and its capacity to raise an antitumour immune response. The study explores the efficacy of SDT in combination with nanotechnology against pancreatic ductal adenocarcinoma. METHODS A nanoparticulate formulation (HPNP) based on a cathepsin B-degradable glutamate-tyrosine co-polymer that carries hematoporphyrin was used in this study for the SDT-based treatment of PDAC. Cathepsin B levels in BxPC-3 and PANC-1 cells were correlated to cellular uptake of HPNP. The HPNP efficiency to induce a sonodynamic effect at varying ultrasound parameters, and at different oxygenation and pH conditions, was investigated. The biodistribution, tumour accumulation profile, and antitumour efficacy of HPNP in SDT were examined in immunocompetent mice carrying bilateral ectopic murine pancreatic tumours. The immune response profile of excised tumour tissues was also examined. RESULTS The HPNP formulation significantly improved cellular uptake of hematoporphyrin for both BxPC-3 and PANC-1 cells, while increase of cellular uptake was positively correlated in PANC-1 cells. There was a clear SDT-induced cytotoxicity at the ultrasound conditions tested, and the treatment impaired the capacity of both BxPC-3 and PANC-1 cells to form colonies. The overall acoustic energy and pulse length, rather than the power density, were key in eliciting the effects observed in vitro. The SDT treatment in combination with HPNP resulted in 21% and 27% reduction of the target and off-target tumour volumes, respectively, within 24 h. A single SDT treatment elicited an antitumour effect that was characterized by an SDT-induced decrease in immunosuppressive T cell phenotypes. CONCLUSION SDT has significant potential to serve as a monotherapy or adjunctive treatment for inoperable or borderline resectable PDAC.

Abstract
Absolute or relative hyperglucagonaemia is a characteristic of both Type 1 and Type 2 diabetes, resulting in fasting hyperglycaemia due in part to increased hepatic glucose production and lack of postprandial suppression of circulating glucagon concentrations. Consequently, therapeutics that target glucagon secretion or biological action may be effective antidiabetic agents. In this regard, specific glucagon receptor (GCGR) antagonists have been developed that exhibit impressive glucose-lowering actions, but unfortunately may cause off-target adverse effects in humans. Further to this, several currently approved antidiabetic agents, including GLP-1 mimetics, DPP-4 inhibitors, metformin, sulphonylureas and pramlintide likely exert part of their glucose homeostatic actions through direct or indirect inhibition of GCGR signalling. In addition to agents that inhibit the release of glucagon, compounds that enhance the transdifferentiation of glucagon secreting alpha-cells towards an insulin positive beta-cell phenotype could also help curb excess glucagon secretion in diabetes. Use of alpha-cell toxins represents another possible strategy to address hyperglucagonaemia in diabetes. In that respect, research from the 1920 s with diguanides such as synthalin A demonstrated effective glucose-lowering with alpha-cell ablation in both animal models and humans with diabetes. However, further clinical use of synthalin A was curtailed due its adverse effects and the increased availability of insulin. Overall, these observations with therapeutics that directly target alpha-cells, or GCGR signaling, highlight a largely untapped potential for diabetes therapy that merits further detailed consideration.

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
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
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
Abstract
Background
The emergence of immune checkpoint inhibitors (ICI’s) in the past decade has proven transformative in the area of immuno-oncology. The PD-1 / PD-L1 axis has been particularly well studied and monoclonal antibodies developed to block either the receptor (anti PD-1) or its associated ligand (anti PD-L1) can generate potent anti-tumour immunity in certain tumour models. However, many “immune cold” tumours remain unresponsive to ICI’s. Sonodynamic therapy (SDT) is a targeted anti-cancer treatment that uses ultrasound to activate a sensitiser with the resulting generation of reactive oxygen species (ROS) causing direct cell death. SDT has also been shown to stimulate the adaptive immune system in a pre-clinical cancer model. We investigate the ability of combining ICI and microbubble mediated SDT at controlling tumour growth in a bilateral pancreatic cancer model.
Methods
Preparation of O2MB-RB are shown below (scheme 1). Cytotoxicity of SDT and immunotherapy in-vivo are illustrated below (Figure 1). Figure 1 highlights that T110299 cells were subcutaneously implanted in the right and left dorsum of C57 mice. Group 1 received an IP injection of anti-mouse PD-L1 antibody (10mg/kg). After 2 hours, mice in this group received an IV injection of O2MB-RB suspension while receiving ultrasound applied to the right-hand-side (target) tumour. Group 2 received the same as Group 1 but no anti PD-L1 antibody; Group 3 received anti-PD-L1 antibody alone and Group 4 remained untreated. Flow cytometry analysis were carried out to investigate tumour infiltrating CD4+ and CD8+ T-lymphocytes.
Results
The results demonstrated a significant 287% decrease in tumour volume when compared to untreated animals 11 days following the initial treatment with SDT, which reduced further to 369% when SDT was combined with anti-PD-L1 ICI treatment. Analysis of residual tumour tissues remaining after treatment revealed increased levels of infiltrating CD4+ and CD8+ T-lymphocytes (respectively 4.65 and 3.16-fold more) in the off-target tumours of animals where the target tumour was treated with SDT and anti-PD-L1, when compared to untreated tumours. These results suggest that SDT treatment elicits an adaptive immune response that is potentiated by the anti-PD-L1 ICI in this particular model of pancreatic cancer.
Conclusions
In conclusion, microbubble mediated SDT treatment of a target tumour in a bilateral tumour model of pancreatic cancer, enables growth control at both the target and off-target tumours which is further enhanced when combined with anti-PD-L1 ICI treatment. Combining SDT with anti-PD-L1 ICI treatment, which is also well tolerated, could provide an attractive treatment option for pancreatic cancer, particularly for patients with advanced disease who may not be physically capable of undertaking a toxic chemotherapy regimen.

Abstract
Abstract
Background
Pancreatic cancer remains a significant therapeutic challenge and its poor prognosis has remained relatively unchanged for the past 40 years. Pancreatic tumours are highly desmoplastic and impenetrable lesions in which both gas and mass transfer is severely compromised. This leads to the development of hypoxia within the tumour and this compromises therapeutic approaches that rely on cytotoxic reactive oxygen species, e.g. photodynamic therapy, sonodynamic therapy and radiotherapy. Hypoxia also results in a relatively low pH within the tumour microenvironment. Here we describe a pH sensitive nanoparticle that can generate oxygen in the tumour and enhance ROS generating therapeutic approaches.
Methods
CaO2 NPs were generated by exposing to low frequency ultrasound and subsequently coated using a polymethacrylate polymer that becomes soluble at pH 6.4. For some studies, the sonosensitiser, Rose Bengal was attached to the particles. Oxygen generation in tumours (BxPC3) was demonstrated by inserting a dissolved oxygen probe into tumours following IV administration of particles. Particles were also employed together with photodynamic therapy (PDT) and sonodynamic therapy (SDT) using human xenograft and syngeneic pancreatic tumour models. In some cases, tumour tissues were recovered and analysed for tumour infiltrating immune cells using flow cytometry.
Results
Conclusions
Coating CaO2 nanoparticles with a pH sensitive polymer provides in situ oxygen generation in tumours. Transient provision of oxygen enhances therapies that depend on the generation of cytotoxic reactive oxygen species. When used with SDT, and using a bilateral syngeneic pancreatic tumour model, a powerful abscopal effect was observed and this was shown to be immune-mediated. The above data suggest that the particles may be exploited to enhance other therapies that depend on the generation of ROS, e.g. radiotherapy, and further suggest that the approach can be used to treat either local or disseminated forms of pancreatic cancer.

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
The emergence of immune checkpoint inhibitors (ICI's) in the past decade has proven transformative in the area of immuno-oncology. The PD-1/PD-L1 axis has been particularly well studied and monoclonal antibodies developed to block either the receptor (anti PD-1) or its associated ligand (anti PD-L1) can generate potent anti-tumour immunity in certain tumour models. However, many "immune cold" tumours remain unresponsive to ICI's and strategies to stimulate the adaptive immune system and make these tumours more susceptible to ICI treatment are currently under investigation. Sonodynamic therapy (SDT) is a targeted anti-cancer treatment that uses ultrasound to activate a sensitiser with the resulting generation of reactive oxygen species (ROS) causing direct cell death by apoptosis and necrosis. SDT has also been shown to stimulate the adaptive immune system in a pre-clinical model of colorectal cancer. In this manuscript, we investigate the ability of microbubble mediated SDT to control tumour growth in a bilateral tumour mouse model of pancreatic cancer by treating the target tumour with SDT and observing the effects at the off-target untreated tumour. The results demonstrated a significant 287% decrease in tumour volume when compared to untreated animals 11 days following the initial treatment with SDT, which reduced further to 369% when SDT was combined with anti-PD-L1 ICI treatment. Analysis of residual tumour tissues remaining after treatment revealed increased levels of infiltrating CD4+ and CD8+ T-lymphocytes (respectively 4.65 and 3.16-fold more) in the off-target tumours of animals where the target tumour was treated with SDT and anti-PD-L1, when compared to untreated tumours. These results suggest that SDT treatment elicits an adaptive immune response that is potentiated by the anti-PD-L1 ICI in this particular model of pancreatic cancer.

Abstract
Sonodynamic therapy (SDT) is an emerging stimulus-responsive approach for the targeted treatment of solid tumours. However, its ability to generate stimulus-responsive cytotoxic reactive oxygen species (ROS), is compromised by tumour hypoxia. Here we describe a robust means of preparing a pH-sensitive polymethacrylate-coated CaO2 nanoparticle that is capable of transiently alleviating tumour hypoxia. Systemic administration of particles to animals bearing human xenograft BxPC3 pancreatic tumours increases oxygen partial pressures (PO2) to 20-50 mmHg for over 40 min. RT-qPCR analysis of expression of selected tumour marker genes in treated animals suggests that the transient production of oxygen is sufficient to elicit effects at a molecular genetic level. Using particles labelled with the near infra-red (nIR) fluorescent dye, indocyanine green, selective uptake of particles by tumours was observed. Systemic administration of particles containing Rose Bengal (RB) at concentrations of 0.1 mg/mg of particles are capable of eliciting nanoparticle-induced, SDT-mediated antitumour effects using the BxPC3 human pancreatic tumour model in immuno-compromised mice. Additionally, a potent abscopal effect was observed in off-target tumours in a syngeneic murine bilateral tumour model for pancreatic cancer and an increase in tumour cytotoxic T cells (CD8+) and a decrease in immunosuppressive tumour regulatory T cells [Treg (CD4+, FoxP3+)] was observed in both target and off-target tumours in SDT treated animals. We suggest that this approach offers significant potential in the treatment of both focal and disseminated (metastatic) pancreatic cancer.

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
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
Background Diagnosis of lymph node (LN) metastasis in melanoma with non-invasive methods is challenging. 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
This paper presents downstream cost-benefit analysis for electronic waste (e-waste) recycling workers in Pakistan, a country that both generates large quantities of e-waste domestically and imports a significant amount from developed countries. Financial cost-benefit elements - reduction in productive capacity, lost wages, medical expenses, wages (and meals) and non-financial cost-benefit elements - opportunity cost, cost of illiteracy and value of life have been quantified. Primary data collected on site was analyzed using quantitative and qualitative methods. The estimated total net economic cost to recycling workers is between Rs.34,069 and Rs.85,478 (US$ 203-5101) per month or an average of Rs.50,363 (US$ 300) per worker. This main finding suggests that cost exceeds by 2.6-4.7 times the estimated economic benefits derived by these workers. Related qualitative data suggests government and owners of recycling businesses are largely blind to many of the less visible costs of this industry, while recycling workers and their families appear trapped in a vicious cycle of poverty. Understanding that what can be measured can be managed and improved, a systematic assessment of informal recycling based on identified impact factors may help mitigate and ideally also motivate a shift towards formal processing that would reduce the downstream negative impacts, both visible and hidden.

Abstract
The major unmet need and crucial challenge hampering the exciting potential of RNAi therapeutics in ophthalmology is to find an effective, safe and non-invasive means of delivering siRNA to the cornea. Although all tissues of the eye are accessible by injection, topical application is preferable for the frequent treatment regimen that would be necessary for siRNA-induced gene silencing. However, the ocular surface is one of the more complex biological barriers for drug delivery due to the combined effect of short contact time, tear dilution and poor corneal cell penetration. Using nanotechnology to overcome the challenges, we developed a unique silicon-based delivery platform for ocular delivery of siRNA. This biocompatible hybrid of porous silicon nanoparticles and lipids has demonstrated an ability to bind nucleic acid and deliver functional siRNA to corneal cells both in vitro and in vivo. Potent transfection of human corneal epithelial cells with siRNA-ProSilic® formulation was followed by a successful downregulation of reporter protein expression. Moreover, siRNA complexed with this silicon-based hybrid and applied in vivo topically to mice eyes penetrated across all cornea layers and resulted in a significant reduction of the targeted protein expression in corneal epithelium. In terms of siRNA loading capacity, system versatility, and potency of action, ProSilic provides unique attributes as a biodegradable delivery platform for therapeutic oligonucleotides.

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.
