Abstract
METHODS 18F-FDG brain PET and clinical score were collected in 85 patients with dementia and 125 healthy controls (HC). Patients were assigned to various form of dementia on the basis of clinical evaluation, follow-up and voxels comparison with HC using a two-sample Student's t -test, to determine the regions of brain involved. Radiomic analysis was performed on the whole brain after normalization to an optimized template. After feature selection using the minimum redundancy maximum relevance method and Pearson's correlation coefficients, a Neural Network model was tested to find the accuracy to classify HC and demented patients. Twenty subjects not included in the training were used to test the models. The results were compared with those obtained by conventional CNN model. RESULTS Four radiomic features were selected. The validation and test accuracies were 100% for both models, but the probability scores were higher with radiomics, in particular for HC group ( P = 0.0004). CONCLUSION Radiomic features extracted from standardized PET whole brain images seem to be more accurate than CNN to distinguish patients with and without dementia.

Abstract
The negative symptoms of schizophrenia are responsible for patients' worse quality of life. The association with cognitive deficits impairs clinical and psychopathological conditions. Our small 5-year observational study evaluated the efficacy of clozapine in negative and cognitive symptoms in schizophrenia inpatients. The overall results showed a significant improvement in the mean total scores of the BNSS and PANSS (at baseline (T0) vs five years (T3)). The improvement was also in some negative subscales (PANSS Negative Factor subscale) but not in others and the Epitrack tool. The overall results showed that clozapine is a useful therapeutic tool that does not affect the cognitive decline of these patients.

Abstract
The spillage of oil causes severe and long-lasting impacts on both the environment and human life. It is crucial to carefully reconsider the methods and techniques currently employed to recover spilled oil in order to prevent any possible secondary pollution and save time. Therefore, the techniques used to recover spilled oil should be readily available, highly responsive, cost-effective, environmentally safe, and, last but not least, they should have a high sorption capacity. The use of sorbents obtained from natural materials is considered a suitable approach for dealing with oil spills because of their exceptional physical characteristics that support sustainable environmental protection strategies. This article presents a novel sorbent material, which is a composite siloxane foam filled with bentonite clay, aimed at enhancing the hydrophobic and oleophilic behavior of the material. The thermal treatment of bentonite optimizes its sorption capacity by eliminating water, and increasing the surface area, and, consequently, its interaction with oils. In particular, the maximum sorption capacity is observed in kerosene and naphtha for the bentonite clay thermally treated at 600 °C, showing an uptake at saturation of 496.8% and 520.1%, respectively. Additionally, the reusability of the composite foam is evaluated by squeezing it after reaching its saturation point to determine its sorption capacity and reusability.

Abstract
Despite natural fibers gaining significant attention in recent decades, their limited performance and poor durability under humid environments cannot allow them to fully replace their synthetic counterparts as reinforcement for structural composites. In such a context, this paper aims to investigate how exposure to a humid/dry cycle affects the mechanical response of epoxy laminates reinforced with flax and glass fibers. In particular, the main goal is to assess the performance evolution of a glass-flax hybridized stacking sequence in comparison with the full glass and flax fiber reinforced composites. To this end, the investigated composites were first exposed to salt-fog for 15 or 30 days and then to dry conditions (i.e., 50% R.H. and 23 °C) for up to 21 days. The presence of glass fibers in the stacking sequence significantly stabilizes the mechanical performance of composites during the humid/dry cycle. Indeed, hybridization of inner flax laminae with outer glass ones, acting as a protective shield, hinders the composite degradation due to the humid phase also promoting performance recovery during the dry phase. Hence, this work showed that a tailored hybridization of natural fibers with glass fibers represents a suitable approach to extend the service-life of natural fiber reinforced composites exposed to discontinuous humid conditions, thus allowing their employment in practical indoor and outdoor applications. Finally, a simplified theoretical pseudo-second-order model that aimed to forecast the performance recovery shown by composites was proposed and experimentally validated, highlighting good agreement with the experimental data.

Abstract
In this paper, the tailoring of superhydrophobic surfaces on AA6082 aluminum alloy by chemical etching in an HF/HCl solution, followed by silane self-assembling, was applied for enhanced corrosion protection in the marine field. In particular, different etching times were considered in order to optimize the treatment effect. The results indicate that all the prepared surfaces, after silanization, were characterized by superhydrophobic behavior with a contact angle higher than 150°. The contact and sliding angles strongly depend on the surface morphology at varying etching times. The optimum was observed with an etching time of 20 s, where a microscale coral-like structure coupled with a homogeneous and ordered pixel-like nanostructure was obtained on the aluminum surface showing a Cassie-Baxter superhydrophobic behavior with a water contact angle of 180° and a sliding angle equal to 0°. All superhydrophobic surfaces achieved an enhanced corrosion protection efficiency and impedance modulus up to two orders of magnitude higher than the as-received AA6082 in simulated seawater.

Abstract
In this work, a composite adsorbent coating constituted by high SAPO 34 content and a sulfonated recycled poly (ether ether ketone) was investigated for adsorption heat pump technology. Specifically, the effect of polymer recycling on mechanical and thermal properties, as well as on water vapor adsorption and desorption performance, has been investigated. The degree of sulfonation obtained after 48 h of reaction remained approximately unaltered. The degradation of the polymer due to recycling anticipates the degradation of the C-C bonds of the polymer by about 20 °C without affecting the temperature at which the sulfonic groups degrade. From the mechanical point of view, the coating containing 90% zeolite, due to the use of recycled PEEK, evidenced a worsening of only 11.8% in scratch resistance compared to the virgin one, whereas the adhesive strength exhibited an increase of about 23.2% due to better miscibility of the sulfonated recycled polymer. Adsorption/desorption isobars show an almost similar adsorption capacity of the coating produced with recycled polymer compared to the virgin one, confirming that the water vapor diffusion is not hindered by the polymer matrix during the adsorption/desorption process.

Abstract
INTRODUCTION The COVID-19 pandemic has led to the re-evaluation of some fundamental aspects for the management of emotions and psychological dynamics. Hope and its lack are important factors that have been especially evaluated in caregivers and HCWs. Instead, our study aimed to explore hopelessness among psychiatric rehabilitation center residents with Primary Psychosis. METHODS We recruited 116 inpatients affected by Primary Psychosis (schizophrenia, bipolar disorder, major depression disorder and personality disorder). Hopelessness was sought through the BHS, during the covid-19 pandemic period. They were compared with data from previous studies on HCWs (HealthCare Workers), in the same period, and in the same centre. RESULTS The results obtained in this group of patients showed high total scores on the BHS scale (mean total score: 7.28±SD 3.73). These data are significantly higher than those found in HWs in the same pandemic period (mean total score: 3.74±SD 3.62). Among the different disorders the borderline personality disorder patients have presented the highest score (mean total score: 8.00±SD 3.50). CONCLUSION Understanding resident - and HCWs- level variations in hopelessness may be important for targeting interventions to improve the outcome of residential psychiatric patients.

Abstract
BackgroundAmong immunocompromised patients with immune mediated inflammatory diseases (IMIDs), those undergoing therapy with B cell depleting agents are among the most vulnerable to both severe COVID-19 disease and sub-optimal response to COVID-19 vaccines(1). Numerous studies have documented suppressed humoral, but relatively maintained cell mediated, responses to COVID-19 vaccines in these patients. However, the clinical significance of such immunity in terms of protection from infection and its sequelae are poorly understood. We have analyzed a large cohort of vaccinated IMIDs patients undergoing B cell depleting therapy for the presence of breakthrough infection and assessed their outcomes.Objectives:To define the frequency and outcomes of COVID-19 breakthrough infection in fully or partially vaccinated IMIDs patients receiving B cell depleting therapies.To assess the characteristics and risk factors for severe outcomes and death.MethodsAll pharmacy records from within a large health care system were electronically searched for patients undergoing B cell depleting therapies with approved monoclonal antibodies in 2020. Records with ICD codes for IMIDs but not malignancies were included; patients must also have had at least one documented COVID-19 vaccine. From this cohort all patients with breakthrough COVID-19 disease from time of 1st vaccination through December 15, 2021 were identified; each record was hand-reviewed to extract clinical data including vaccine history, demographics, comorbidities, use of monoclonal antibodies, dose and timing of B cell depleting therapy, and outcomes as assessed by an 8 point NIH ordinal scale. Univariate and multivariable logistic/proportional-odds regression models were used to examine the risk factors for severe outcomes.ResultsA total of 1677 IMIDs patients were identified who received any B cell depleting monoclonal antibody and at least one COVID-19 vaccine in 2021. From this cohort 74 patients (4.4%) experienced a breakthrough COVID-19 infection. Among the breakthrough patients 34 (46%) had a rheumatic disease (RA 11, AAV 15, SLE 2), 34 (46%) had CNS inflammatory disease (MS 32, 2 other), and 6 (8%) had immune hematologic/miscellaneous diseases. Four patients had a previous history of COVID-19 infection. Overall 24 (35%) were hospitalized with 11 patients requiring critical level care (15%) and 6 deaths (8 %). All fatal cases had rheumatic diseases. Monoclonal antibodies were given as outpatient therapy to 21 patients and among these only 1 patient was hospitalized without requiring O2 and none died. In univariate analysis only number of comorbidities had a significant positive effect (p=.001) on severe outcomes (i.e. groups 1-4 vs. groups 5-8: Table 1) while monoclonal antibody therapy was associated with more favorable outcomes (p=.005 group 1-2 vs.3-8, Table 1). There were no associations between the dose, duration or timing of the B cell therapy, concomitant therapies including glucocorticoids, vaccine status (incomplete, complete, boosted) or date of vaccination with severe outcomes.ConclusionIn IMIDs patients treated with B cell depleting therapies breakthrough infections are common with many experiencing severe outcomes. Concomitant comorbidities were associated with risk of severe disease. Monoclonal antibody therapy was used in only 28% but was associated with enhanced clinical outcomes with only 1 in 21 requiring hospitalization and zero mortality. This population of immunocompromised patients remains vulnerable to COVID-19 disease despite vaccination. More aggressive use of outpatient management with monoclonal antibody therapy and other preventive and therapeutic measures are urgently needed.Reference[1]Samuel Bitoun et al Rituximab impairs B-cell response but not T-cell response to COVID-19 vaccine in auto-immune diseases First published: 28 December 2021 Arthritis and Rheumatology https://doi.org/10.1002/art.42058Disclosure of Interestscassandra calabrese Speakers bureau: Sanofi-regeneron, Consultant of: Sanofi-regeneron, Elizabeth Kirchner Consultant of: Janssen, M Elaine Husni Consultant of: Abbvie, BMS, Novartis, Lilly, Pfizer, UCB, Regeneron, Janssen, Brandon Moss Consultant of: Biogen advisory board, Grant/research support from: Genentech/Roche and Novartis as part of investigator-initiated studies, Anthony Fernandez Consultant of: Consulting: AbbVie, Novartis, Mallinckrodt, UCB, BMS, Boehringer Ingelheim, Alexion, Grant/research support from: Research: AbbVie, Novartis, Pfizer, Corbus, Mallinckrodt, Yuxuan Jin: None declared, Leonard Calabrese Speakers bureau: Sanofi, Janssen, AbbVie, ChemoCentryx, GSK, AstraZeneca, Consultant of: Sanofi, Jansen, AbbVie, ChemoCentryx, GSK, AstraZeneca, BMS, Genentech

Abstract
Abstract
The implicit finite difference and fourth order Runge-Kutta method are used both to solve the heat transfer problem in the pultrusion reaction and to calculate the temperature and conversion distributions within a thermoset composite profile. The aim of our work is to study the influence of a rubbery phase added to the epoxy matrix in production conditions. The results have shown that the rubber modified systems have a low exothermic temperature peak value, so that neither the amount of cured resin nor the final product properties are limited.
First of all we will show that the phase transition (gelation and vitrification) zones within the die change as the amount of rubber varies in the resin. The relationship between the position and of these zones and the resin systems will be discussed. We calculate the residual thermal stresses for all the investigated fibre/resin systems, showing a reduction when the rubber amount increases in the epoxy blend.

Abstract
In the shipbuilding sector (cruises, ferries, etc.), the design and control constraints applied to improve the fire safety conditions of naval vessels are acquiring important relevance. Research activities have aimed at enhancing the fire resistance of structures and surface coatings to make ships’ working environments safer, trying to combine performance, durability and low costs. In this context, the aim of this paper is to develop and optimize flame-retardant coatings for naval applications. In particular, in an acrylic carrier, Mg(OH)2 and Al(OH)3 fillers were added to exalt the fire resistance capabilities of the coatings. Furthermore, the effect of the particle size of the hydroxides on the coatings’ fire resistance was investigated. The coatings were studied by structural (XRD), thermo-physical (TG) and morphological (SEM) characterization to evaluate their thermal stability and the damage level due to fire exposition. Specifically, fire reaction tests were applied at different fire exposure times (15 s, 30 s) to estimate the fire resistance of the proposed coatings compared to the commercial reference. The results show that the coatings based on aluminum and magnesium hydroxides exhibit favorable fire resistance. Particularly, effective performances were observed for short times of exposure to direct flames. Furthermore, the temperature monitoring of the steel alloy support during the test allowed us to evaluate the degree of insulation of the coating, highlighting a better result for the specimen filled with Mg(OH)2, making this product promising for its optimization in this context.

Abstract
Superhydrophobic surfaces on 6082 aluminum alloy substrates are tailored by low-cost chemical surface treatments coupled to a fluorine-free alkyl-silane coating deposition. In particular, three different surface treatments are investigated: boiling water, HF/HCl, and HNO3/HCl etching. The results show that the micro-nano structure and the wetting behavior are greatly influenced by the applied surface texturing treatment. After silanization, all the textured surfaces exhibit a superhydrophobic behavior. The highest water contact angle (WCA, ≈180°) is obtained by HF/HCl etching. Interestingly, the water sliding angle (WSA) is affected by the anisotropic surface characteristics. Indeed, for the HF/HCl and the HNO3/HCl samples, the WSA in the longitudinal direction is lower than the transversal one, which slightly affects the self-cleaning capacity. The results point out that the superhydrophobic behavior of the aluminum alloys surface can be easily tailored by performing a two-step procedure: (i) roughening treatment and (ii) surface chemical silanization. Considering these promising results, the aim of further studies will be to improve the knowledge and optimize the process parameters in order to tailor a superhydrophobic surface with an effective performance in terms of stability and durability.

Abstract
Background:Busy rheumatologists may assess disease activity and risk for radiographic progression (RP) in RA with informal, qualitative versions of evaluator and/or patient global assessments (EGA and PGA). RA patient care may be improved by having a convenient, objective disease activity measure that predicts risk for RP more accurately than EGA or PGA.Objectives:To compare the abilities of MBDA score, patient global assessment and evaluator global assessment to assess risk for radiographic progression (RP), and to assess the ability of MBDA score to predict RP among patients with concordant or discordant PGA and EGA.Methods:Patients were pooled from two RCTs of patients with recent onset RA treated with conventional and biologic DMARDs (OPERA and SWEFOT, N=386) and from a registry of patients with predominantly established RA and diverse treatments (BRASS, N=380). Pearson correlations were determined between MBDA scores (adjusted for the effects of age, sex and adiposity) (scale 1-100), PGA and EGA (each on a scale of 1-10) at baseline. PGA and EGA were considered discordant when they differed by >2.5. Univariable logistic regression assessed ability to predict RP (change in TSS >5 over 1 year) for MBDA score, PGA and EGA as continuous variables; and for discordance of PGA and EGA as 2-level (concordant vs. discordant) or 3-level (PGA>EGA, concordant, EGA>PGA) categorical variables. Multivariable regression considered the main effect and interaction terms of the MBDA score, as a continuous variable, paired with each other variable, to test the ability of each pair to assess risk of RP. All models included a random effect on cohort. Odds ratios were reported for every 10-unit increase in MBDA score. Frequency of RP was determined in subgroups with MBDA score low (<30), moderate (30-44) or high (>44) for patient groups based on PGA/EGA concordance or discordance.Results:The 766 patients studied were 76% female, 76% positive for RF and/or anti-CCP Ab, with mean age 55 years, DAS28-CRP 4.7, CRP 22 mg/L, CDAI 26, SJC 9.1, PGA 4.4, EGA 3.4, MBDA score 53. No interaction was seen between MBDA score and type of cohort (early vs established RA). PGA and EGA were discordant in 294 of 766 (38%) patients and were weakly to moderately correlated (r=0.38). Among discordant patients, PGA was >EGA in 227 cases and EGA was >PGA in 67 cases. Correlations between MBDA score and PGA or EGA were r=0.41 and r=0.34, respectively. In univariable analyses, MBDA score was a statistically significant predictor of radiographic progression (OR=1.53, p=6.3x10-8) whereas PGA, EGA, 2-level discordance and 3-level discordance were not (p=0.38, 0.47, 0.74, 0.83, respectively). In multivariable analyses, significant interactions were observed between MBDA score and discordance (2-level, p=0.0029; 3-level, p=0.0087). The interaction analysis demonstrated, in PGA/EGA-concordant patients, low risk of radiographic progression when MBDA score was low and elevated risk when it was high (OR=1.33 [1.1, 1.59]). A relationship between MBDA score and RP risk was also demonstrated, with heightened trend, among discordant patients with PGA >EGA (OR=2.04 [1.53, 2.81]) and EGA >PGA (OR=3.43 [1.37, 13.8]) (Figure 1).Conclusion:MBDA score was a significant predictor of radiographic progression, whereas PGA and EGA were not. MBDA score predicted progression whether PGA and EGA were concordant or discordant. These results suggest that MBDA score detects joint-damaging disease activity more accurately than PGA and EGA and it does so whether or not PGA and EGA are in agreement.Disclosure of Interests:Leonard Calabrese Grant/research support from: AbbVie, Bristol-Myers Squibb, Cresecendo, Genentech, Gilead, GlaxoSmithKline, Horizon, Janssen, Novartis, and Sanofi., Michael E.

Abstract
Background:The safety and efficacy of the oral Janus kinase inhibitor upadacitinib (UPA) has been evaluated across a spectrum of patients with rheumatoid arthritis (RA) in the phase 3 SELECT clinical program.1–6Objectives:To describe the long-term integrated safety profile of UPA relative to active comparators (cutoff date: June 30, 2020) in patients with RA treated in the SELECT clinical program.Methods:This analysis included updated data from 6 randomized controlled UPA RA trials.1–6 Treatment-emergent adverse events (TEAEs; onset after first dose and ≤30 days after last dose of study drug or ≤70 days for adalimumab [ADA]) including AEs of special interest were summarized as follows: pooled UPA 15 mg once daily (QD; UPA15, 6 trials); pooled UPA 30 mg QD (UPA30, 4 trials); methotrexate (MTX, 1 trial), and ADA (1 trial). TEAEs were reported as exposure-adjusted adverse event rates (EAERs; events/100 patient-years [E/100 PY]), which included both incident and recurrent events.Results:4413 patients (UPA15, n=3209; UPA30, n=1204) received ≥1 dose of UPA, providing 10,115.4 PY of exposure. EAERs for AEs, serious AEs (SAEs), and AEs leading to discontinuation were similar for UPA15, MTX, and ADA; rates for UPA30 were numerically higher than UPA15 (Table 1). The most common AEs were upper respiratory tract infection, nasopharyngitis, and urinary tract infection for both UPA doses, and for UPA30 only, increased creatine phosphokinase (CPK). Pneumonia was the most common SAE for both UPA15 and UPA30. Serious infection rates were similar for UPA15, MTX, and ADA but higher for UPA30 (Figure 1). Rates of herpes zoster (HZ) were higher for both UPA groups (dose-dependent) vs MTX and ADA. Most HZ cases with UPA were non-serious (94%) and involved a single dermatome (74%). CPK elevations, which were mostly asymptomatic, were more common for both UPA groups (dose-dependent) vs MTX and ADA. EAERs of adjudicated gastrointestinal perforations were <0.1 and 0.2 E/100 PY for UPA15 and UPA30, respectively. Rates of non-melanoma skin cancer (due in part to more recurrent events with UPA30), anemia, and neutropenia were higher with UPA30 vs other treatment groups. Events of anemia and neutropenia were generally mild/moderate and treatment discontinuation due to these events was uncommon (<0.4%). Rates of other AEs of special interest, including major adverse cardiovascular and venous thromboembolic events, were broadly similar across treatment groups. The rate of deaths in UPA-treated patients with RA was not higher than expected for the general population (standardized mortality ratio [95% confidence interval (CI)]: UPA15, 0.43 [0.29, 0.63]; UPA30, 0.68 [0.40, 1.08]).Table 1.TEAEs in patients treated with UPA, MTX, and ADAUPA 15 mg QDUPA 30 mg QDADA 40 mg EOWMTXn32091204579314ExposureTotal, PY7023.83091.61051.8637.4Mean (SD), weeks114 (64)134 (66)95 (70)106 (67)Median (range), weeks136 (0, 232)160 (0, 231)118 (2, 231)144 (1, 221)E/100 PY (95% CI)Any AE230.7 (227.2, 234.3)283.6 (277.7, 289.6)216.6 (207.8, 225.7)227.8 (216.2, 239.8)Any SAE13.0 (12.2, 13.9)18.8 (17.3, 20.4)13.3 (11.2, 15.7)10.4 (8.0, 13.2)Any AE leading to discontinuation of study drug5.6 (5.0, 6.1)8.5 (7.5, 9.6)6.8 (5.3, 8.5)6.3 (4.5, 8.5)Deathsa0.4 (0.3, 0.6)0.6 (0.3, 0.9)0.9 (0.4, 1.6)0.5 (0.1, 1.4)aBoth treatment and non-treatment-emergent deathsEOW, every other weekConclusion:The updated safety profile of UPA with up to 4.5 years of exposure in patients with RA was comparable to previous analyses,7 with no new safety signals reported.

Abstract
Background:Upadacitinib (UPA) is an oral JAK inhibitor approved for the treatment of rheumatoid arthritis (RA). The background rate of herpes zoster (HZ) in patients (pts) with RA is around 0.98/100 person years (PY)1. Pts with RA receiving JAK inhibitors have been reported to have an increased risk of HZ.Objectives:To evaluate the incidence and risk factors for HZ in pts with RA receiving UPA relative to active comparators in the Phase 3 clinical trial program.Methods:The incidence rate of HZ was determined in pts receiving UPA (as monotherapy [mono] or combination therapy) in five randomized Phase 3 trials (SELECT-EARLY, SELECT-MONOTHERAPY, SELECT-NEXT, SELECT-COMPARE, and SELECT-BEYOND), of which 4 evaluated both the UPA 15 and 30 mg once-daily (QD) doses and 1 trial (SELECT-COMPARE) evaluated only the 15 mg QD dose. Incidence of HZ was also determined in pts receiving adalimumab (ADA) + methotrexate (MTX) in SELECT-COMPARE and MTX mono in SELECT-EARLY. Risk factors for HZ were assessed using univariate and multivariate Cox regression models. Data cut-off was 30 June 2019.Results:Overall, 2629 pts who received UPA 15 mg QD (4565.8 patient-years [PY]), 1204 pts who received UPA 30 mg QD (2309.7 PY), 579 pts who received ADA + MTX (768.6 PY), and 314 pts who received MTX mono (456.0 PY) were analyzed. Fewer than 5% of pts across the treatment groups reported prior HZ vaccination. HZ (n/100 PY [95% CI]) occurred in 142 pts (3.1 [2.6–3.7]) with UPA 15 mg, 126 pts (5.5 [4.5–6.5]) with UPA 30 mg, 8 pts (1.0 [0.4–2.1]) with ADA + MTX, and 5 pts (1.1 [0.4–2.6]) with MTX mono. Most of the HZ cases (~71%) with UPA (Table) and all cases with ADA + MTX and MTX mono involved a single dermatome. Ophthalmic involvement was seen in 6 (4.2%) and 3 (2.4%) cases in the UPA 15 and 30 mg groups, respectively, and unilateral involvement with multiple dermatomes was seen in 26 (18.3%) and 23 (18.3%) cases. There was a single case of HZ meningitis reported in a Japanese pt on UPA 30 mg. In multivariate analyses, prior history of HZ and Asian region were associated with an increased risk of HZ in both the UPA groups (p≤0.01;Figure). In addition, pts ≥65 years old had increased risk of HZ in the 15 mg group.Conclusion:HZ events in pts with RA receiving UPA were more common in the 30 mg vs 15 mg group, and in both UPA groups compared with the ADA + MTX and MTX groups.References:[1]Smitten AL, et al.

Abstract
Background:The safety and efficacy of upadacitinib (UPA), an oral JAK inhibitor, was evaluated in the phase 3 SELECT clinical program, which included 5 randomized, double-blind, controlled trials across a spectrum of rheumatoid arthritis (RA) patients (pts)1-5.Objectives:To describe the long-term integrated safety profile of UPA relative to active comparators in pts with RA treated in the SELECT program up to a cut-off date of 30 June 2019.Methods:Treatment-emergent adverse events (TEAEs: AE onset ≥first dose and ≤30 days after last dose) were summarized for the following: methotrexate (MTX, 1 trial, mean exposure 76 wks); adalimumab (ADA, 1 trial, mean exposure 69 wks); pooled UPA 15 mg (5 trials, mean exposure 90 wks); pooled UPA 30 mg (4 trials, mean exposure 100 wks). TEAEs are reported as exposure-adjusted event rates (EAERs; events/100 patient years [E/100PYs]).Results:3833 pts received ≥1 dose of UPA 15 mg [n=2629, 4565.8 PYs] or 30 mg [n=1204, 2309.7 PYs] QD, with no option to switch doses. More than half of pts received UPA for ≥96 wks (median: UPA 15, 101.9 wks; UPA 30: 111.7 wks). The EAERs of overall SAEs and AEs leading to discontinuation on UPA 15 mg were comparable to MTX and ADA; rates on UPA 30 mg were numerically higher than UPA 15 mg (Table). The most common AEs (≥5 E/100 PYs) reported with UPA 15 mg were upper respiratory tract infection (URTI), nasopharyngitis, urinary tract infection (UTI), bronchitis, increased CPK, and increased ALT. For UPA 30 mg, the most common AEs reported were URTI, UTI, increased CPK, nasopharyngitis, bacterial bronchitis, and herpes zoster (HZ). Overall rates of serious infections and opportunistic infections were comparable between UPA 15 mg, MTX, and ADA groups but were higher on UPA 30 mg (Figure). Rates of HZ were higher in both UPA groups (30 mg higher than 15 mg) vs MTX and ADA. The majority of HZ cases were non-serious (96%) and involved a single dermatome (74%). Rates of VTE were comparable across treatment groups (0.3-0.5/100 PYs), as were rates of adjudicated MACE and malignancies (excluding NMSC). Rates of NMSC in UPA 15 mg and ADA were similar, with numerically higher rates on UPA 30 mg. SMR analysis demonstrated that the number of deaths in pts with RA exposed to UPA was not higher than what would be expected for the general population.Conclusion:Through long-term follow-up, the integrated safety profile of UPA remained consistent with previous analyses, with no new signals identified.References:[1]Burmester,et al.Lancet2018;391:2503-12.[2]Genovese,et al.Lancet2018;391:2513-24.[3]Smolen,et al.Lancet2019;393:2303-11.[4]Fleischmann,et al.Arthritis Rheumatol2019;71:1788-1800.[5]van Vollenhoven,et al.Arthritis Rheumatol2018;70(Suppl 10).Table.Overall TEAEs for UPA and Active Comparators (E/100 PYs [95% CI])MTXn=314(456.0 PYs)ADA 40 mg eown=579(768.6 PYs)UPA 15 mg QDn=2629(4565.8 PYs)UPA 30 mg QDn=1204(2309.7 PYs)Any AE271.7 (256.8, 287.3)242.3 (231.4, 253.5)247.7 (243.2, 252.3)310.6 (303.5, 317.9)Any SAE12.7 (9.7, 16.4)14.6 (12.0, 17.5)12.9 (11.9, 14.0)19.8 (18.0, 21.7)Any AE leading to discontinuation7.7 (5.3, 10.7)8.2 (6.3, 10.5)6.3 (5.6, 7.1)10.0 (8.8, 11.4)Deathsa0.4 (0.1, 1.6)0.8 (0.3, 1.7)0.4 (0.2, 0.6)0.7 (0.4, 1.1)aDeaths included non-treatment emergent deaths: ADA, 1; UPA 15 mg, 3; UPA 30 mg, 3.Disclosure of Interests:Stanley B.

Abstract
Background:Upadacitinib (UPA) is a selective and reversible Janus kinase (JAK) inhibitor with an approved dose of 15 mg once daily (QD) for the treatment of rheumatoid arthritis (RA). Patients (pts) receiving JAK inhibitors have been reported to be at increased risk of developing serious infection events (SIE) and opportunistic infections (OI).Objectives:To evaluate the incidence of SIEs and OIs in pts with RA receiving UPA and active comparators in the Phase 3 SELECT clinical trial program.Methods:The exposure-adjusted event rate (EAER) per 100 patient-years (E/100 PY) of SIEs and OIs was determined in pts receiving UPA in five randomized Phase 3 trials (SELECT-EARLY, SELECT-MONOTHERAPY, SELECT-NEXT, SELECT-COMPARE, and SELECT-BEYOND), of which four evaluated both UPA 15 mg and 30 mg QD doses and one (SELECT-COMPARE) evaluated only UPA 15 mg QD. Incidences of SIEs and OIs were also determined in pts receiving adalimumab (ADA) + methotrexate (MTX) in SELECT-COMPARE and MTX monotherapy in SELECT-EARLY. Data were analyzed descriptively, with no statistical comparisons between groups or doses. Risk factors for SIEs were determined using a univariate Cox regression model. The data cut-off was June 30, 2019.Results:Overall, 2629 pts who received UPA 15 mg, 1204 pts who received UPA 30 mg, 579 pts who received ADA + MTX, and 314 pts who received MTX monotherapy were included in this analysis. The EAERs (E/100 PYs [95% CI]) of SIEs were 3.2 (2.7–3.7) in the UPA 15 mg group, 5.7 (4.8–6.8) in the UPA 30 mg group, 3.9 (2.6–5.6) in pts receiving ADA + MTX, and 3.1 (1.7–5.2) in pts receiving MTX monotherapy. Pneumonia was the most common SIE, with EAERs (E/100 PYs [95% CI]) of 0.7 (0.5–1.0), 1.3 (0.9–1.9), 0.7 (0.2–1.5), and 0.7 (0.1–1.9) in the UPA 15 mg, UPA 30 mg, ADA + MTX, and MTX monotherapy groups, respectively. Rates of OIs (including oral candidiasis and disseminated herpes zoster [HZ]) (E/100 PYs [95% CI]) were 0.7 (0.5–1.0), 1.3 (0.9–1.9), 0.4 (0.1–1.1), and 0 (0–0) in the UPA 15 mg, UPA 30 mg, ADA + MTX, and MTX monotherapy groups, respectively. Oral candidiasis was the most frequent OI with EAERs (E/100 PYs [95% CI]) of 0.4 (0.2–0.6) in the UPA 15 mg group, 0.6 (0.3–1.0) in the UPA 30 mg group, 0.4 (0.1–1.1) in the ADA + MTX group, and 0 (0–0) in the MTX monotherapy group. Serious adverse events of HZ were only reported in the UPA groups (0.2 E/100 PYs [95% CI: 0.1–0.3] and 0.6 E/100 PYs [95% CI: 0.4–1.1] in the UPA 15 mg and 30 mg groups, respectively). Overall, there were 3 (4 coded events), 3, 1, and 0 pts who had active tuberculosis events in the UPA 15 mg, UPA 30 mg, ADA + MTX, and MTX monotherapy groups, respectively. Risk factors for SIEs are shown in the Figure. For both UPA doses, age ≥75 years and smoking were noted to have hazard ratios >1.Conclusion:The incidence rate of SIEs and OIs was higher in the UPA 30 mg group than the UPA 15 mg group. SIEs observed with UPA 15 mg were similar to that seen with ADA although the rates of HZ were higher on UPA. Pts with RA who are ≥75 years old and/or smokers may be at higher risk than other pts with RA for SIEs while receiving UPA.Figure.Univariate analysis of SIE risk factorsDisclosure of Interests:Kevin Winthrop Grant/research support from: Bristol-Myers Squibb, Consultant of: AbbVie, Bristol-Myers Squibb, Eli Lilly, Galapagos, Gilead, GSK, Pfizer Inc, Roche, UCB, Leonard Calabrese Consultant of: AbbVie, GSK, Bristol-Myers Squibb, Genentech, Janssen, Novartis, Sanofi, Horizon, Crescendo, and Gilead, Speakers bureau: Sanofi, Horizon, Crescendo, Novartis, Genentech, Janssen, and AbbVie, Filip van den Bosch Consultant of: AbbVie, Celgene Corporation, Eli Lilly, Galapagos, Janssen, Novartis, Pfizer, and UCB, Speakers bureau: AbbVie, Celgene Corporation, Eli Lilly, Galapagos, Janssen, Novartis, Pfizer, and UCB, Kunihiro Yamaoka Speakers bureau: AbbVie GK, Astellas Pharma Inc., Bristol-Myers Squibb, Chugai Pharmaceutical Co.

Abstract
Background:Immune Checkpoint inhibitors (ICI) have revolutionized cancer therapy by achieving remarkable survival benefits however, at the cost of a myriad of immune-related adverse events (irAEs)[1]. Rheumatic irAE can develop in 5-10% of patients although the true incidence is unknown given the lack of prospective studies [2]. Symptoms are heterogenous and probably underreported with few data available about their management and outcome [3].Objectives:To describe the clinical, biological, and radiological features of the largest cohort of rheumatic irAEs from ICI along with their therapeutic management, outcome and follow-up in real-world practice.Methods:A referral process for emergent rheumatic irAEs was initiated in February 2016 between the oncology and rheumatology departments at the Cleveland Clinic Foundation. All patients were evaluated by authors CC and/or LHC. Patients’ characteristics were retrospectively collected from medical charts after IRB approval.Results:70 patients referred for one or more rheumatic irAEs between February 2016 and January 2020 were included. 66% were male, median age was 60.8 years. Among them, 24 (34%) had pre-existing rheumatic complaints. Melanoma was the most frequent malignancy (56%). ICI therapy included anti-CTLA4 (40%), anti-PD1/L1 (79%), and dual therapy ipilimumab/nivolumab (41%). Rheumatic irAE occurred in a median 4 months after ICI initiation, with phenotypes including inflammatory arthritis (32 patients), sicca-like symptoms (12), polymyalgia rheumatica-like (7), and myositis (2). Oral, intravenous or intraarticular glucocorticoids (GC) were administered to 54 patients (77%). Of these 54 patients, 22 (41%) required long term GC, 19 had bone density scan and 15 received pneumocystis (PJP) prophylaxis. One PJP case, 1 osteoporotic fracture and 2 avascular necrosis cases were reported. 16 patients received conventional DMARDS (23%) and 9 received biologics (13%). ICI therapy was held for rheumatic irAE in 31% of cases and for another systemic irAE in 29%. Median follow-up was 13.6 months, at end of follow-up 51 patients were still on treatment for rheumatic irAE and 41% of them were still symptomatic despite ongoing treatment.Conclusion:Rheumatic irAEs are heterogeneous and often chronic requiring prolonged immunomodulatory therapy. Prospective studies are required to define optimal management of rheumatic irAEs that maintain long-term oncologic outcomes.References:[1]Suarez-Almazor ME, Kim ST, Abdel-Wahab N, Diab A.

Abstract
Over the last decades, natural fiber-reinforced polymer composites (NFRPs) gained great attention in several engineering fields thanks to the reduction of the environmental impact and the end-of-life cost disposal. Unfortunately, the use of NFRPs is limited, mainly due to their weak resistance against humid environments. Since limited literature is available about the evolution of the dynamic mechanical response of NFRPs under aggressive environments, this paper aims to investigate the damping properties of flax, jute and flax/jute epoxy composites exposed to salt-fog up to 60 days. Furthermore, sodium bicarbonate fiber treatment was performed to improve the composites’ durability. The effectiveness of treatment was evidenced for full flax-reinforced composites, whereas no beneficial effect was found for jute composites. Moreover, treated hybrid laminates having outer laminae reinforced with flax showed better damping behavior than their hybrid counterparts during the whole aging campaign.

Abstract
Dental implant biomaterials are expected to be in contact with living tissues, therefore their toxicity and osseointegration ability must be carefully assessed. In the current study, the wettability, cytotoxicity, and genotoxicity of different alumina-zirconia-titania composites were evaluated. The surface wettability determines the biological event cascade in the bioceramic/human living tissues interface. The measured water contact angle indicated that the wettability strongly depends on the ceramic composition. Notwithstanding the contact angle variability, the ceramic surfaces are hydrophilic. The cytotoxicity of human gingival fibroblast cells with materials, evaluated by an (3-(4,5 methylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) test, revealed an absence of any cytotoxic effect. A relationship was found between the cell viability and the wettability. It was subsequently deduced that the cell viability increases when the wettability increases. This effect is more pronounced when the titania content is higher. Finally, a comet test was applied as complementary biocompatibility test to detect any changes in fibroblast cell DNA. The results showed that the DNA damage is intimately related to the TiO2 content. Genotoxicity was mainly attributed to ceramic composites containing 10 wt.% TiO2. Our research revealed that the newly developed high performance alumina-zirconia-titania ceramic composites contain less than 10 wt.% TiO2, and display promising surface properties, making them suitable for dental implantology applications.

Abstract
To meet the increasing demands for effective cleanup technologies to deal with the oil spill accidents that significantly affect the ecological and environmental systems, promising composite materials based on carbon nanotubes containing silicone foams were investigated. Pump oil, kerosene, and virgin naphtha had been used to assess, during sorption tests, foams behavior. Test results highlighted the advantage of the hydrophobic and oleophilic behavior of carbon nanotubes, and their high mechanical strength for oil spill recovery application was studied. In order to better relate the property-structure relationship for this class of materials, the role and influence of functionalized nanotubes on thermo-physical and morphological characteristics of the foams had been evaluated. The results showed how the pristine nanotubes fillers, despite functionalized ones, led to optimal composite foam performances with high hydrophobic (62 mg g−1) and oleophilic (6830 mg g−1 in kerosene oil) characteristics. The evidenced high oil selectivity was a relevant key point in order to consider the suitable material for oil spill recovery applications. Eventually, the proposed configuration exhibited the best thermo-physical performances and high reusability, leading to the optimal cost-benefits option.

Abstract
The aim of the present paper is to study the mechanical performance evolution of pinned hybrid glass-flax composite laminates under environment aging conditions. Hybrid glass-flax fibers/epoxy pinned laminates were exposed to salt-spray fog environmental conditions up to 60 days. With the purpose of assessing the relationship between mechanical performances and failure mechanisms at increasing aging time, single lap joints at varying joint geometry (i.e., hole diameter D and hole distance E from free edge) were characterized after 0 days (i.e., unaged samples), 30 days, and 60 days of salt-fog exposition. Based on this approach, the property-structure relationship of the composite laminates was assessed on these critical environmental conditions. In particular, a reduction of failure strength for long-aging-time-aged samples was observed in the range 20-30% compared to unaged one. Due to the natural fiber degradation in a salt-fog environment, premature catastrophic fractures mode due to shear-out and net-tension were found, related to reduced joint fracture strength. This behavior identifies that this type of joint requires a careful design in order to guarantee an effective mechanical stability of the composite hybrid joint under long-term operating conditions in an aggressive environment.

Abstract
This work investigates the application of novel sorption materials to heat-powered desalination systems. Two ionic liquids 1-ethyl-3-methylimidazolium acetate (Emim-Ac) and 1-ethyl-3-methylimidazolium methanesulfonate (Emim-Oms) were impregnated in two silica supports, namely, Syloid AL-1FP and Syloid 72FP. Emim-Ac and Emim-Oms composite sorbents have been compared on morphology, water vapor sorption equilibrium, and heat of sorption. Fourier-transform infrared spectroscopy shows that the ionic liquid partly self-organizes on the silica surface. When used in a sorption desalination process powered by low grade heat at 60 °C, these composites have exceptionally high theoretical working capacities ranging from 1 to 1.7 gwater gsorbent-1. Experimental tests on a lab scale desalinator show that Emim-Ac/Syloid 72FP in real operating conditions can produce 25 kgwater kgsorbent-1 day-1. To date, this yield is 2.5 times higher than the best achieved with silica gel.

Abstract
The present paper deals with the investigation of quasi-static and dynamic mechanical response of epoxy-based composites reinforced with flax and/or jute plain weave fabrics. In order to evaluate the influence of the stacking sequence, two monolithic laminates reinforced with flax or jute fibers and two hybrid flax/jute laminates were manufactured through the vacuum infusion technique. Furthermore, an eco-friendly and cost-effective surface treatment based on fiber soaking in a sodium bicarbonate solution was employed to improve the fiber-matrix adhesion. The mechanical characterization (by means of quasi-static flexural, dynamic mechanical thermal analysis and Charpy impact tests) allowed to evidence that the sodium bicarbonate treatment leads to noticeable improvement of the mechanical performances of flax reinforced composites, whereas jute composites experience a slight decrease of their mechanical properties. Overall, the hybridization allows to achieve intermediate mechanical properties among those of monolithic composites. Furthermore, the coupled action of hybridization and surface treatment does not lead to a beneficial and reliable effect on the mechanical response of the resulting composites.

Abstract
Aims and Background In stage I oral squamous cell carcinoma, clinical examination and imaging techniques are unable to identify 60-90% of patients at risk of micrometastasis, while the sentinel node biopsy technique allows to avoid the morbidity of elective neck dissection in patients not actually affected by micrometastases. Materials and methods Forty-one T1-T2N0 patients underwent lymphoscintigraphy after peritumoral injection of human albumin labeled with 99Tc. Focal areas of radiotracer uptake were marked on the skin preoperatively. The sentinel lymph node (SLN) was identified by the combined use of blue dye and gamma probe and subsequently removed. Complete neck dissection was then performed in all patients and the histological findings were compared with those of SLN biopsy. Results The SLN was identified in 95% of the patients; in four cases (10%) two SLNs were isolated. In 18% of our patients the SLNs were located outside the expected drainage area. When the histology of the negative SLNs was compared with the pathological status of the neck dissection specimens no false negatives were found. Five SLNs in four patients contained micrometastases and were the only positive lymph nodes. Conclusion SLN biopsy can be a valuable staging technique in T1 and T2 oral cancer with uninvolved neck in patients whose lymphatic drainage of the neck has not been altered by previous surgery or radiotherapy. It provides reliable detection of micrometastasis, indicating which level(s) should be removed ipsilaterally or contralaterally, and allows the surgeon to accurately plan neck dissection, taking into consideration the pattern of lymphatic drainage of each individual patient. In this way unnecessary neck dissection and its morphofunctional sequelae can be avoided in a considerable number of patients.

Abstract
IntroductionPatients with serious psychiatric illness (SMI) have a reduced quality of life and life expectancy than the general population. Metabolic syndrome (MS) is a clinical aspect determining who should be considered to reduce the risk of serious and chronic organic factors, even more significant in the elderly.ObjectivesTo evaluate metabolic screening of elderly patients with severe mental illness (SMI).AimsTo evaluate the importance of routine screening of metabolic parameters in elderly guests of residential facilities with or without SMI; metabolic screening at baseline and after two of hospitalization.MethodsElderly inpatients (44 Tot) with Severe Mental Illness (SMI: bipolar disorder: 34%; schizophrenia: 46%; other: 20%) vs elderly inpatients (78 Tot). Data collected at baseline: psychiatric diagnosis; any previous diagnosis of hypertension, diabetes, dyslipidemia; ECG. At baseline and for two years were administered following scale: BPRS; PANSS; Qli; MMSE, ADL.ResultsAfter two years metabolic screening has recorded at least one of the new interactions between the five factors of MS (ATP III) in 50% of patients with: one (34%); two (21%); three (11%); four (3%) new altered parameters. In MS inpatients, 53% of new metabolic alterations were recorded in 53% (MS inpatients) vs 23% without MS after two years.ConclusionsOur results showed a higher frequency of MS in patients with SMI than comparison subjects. Haloperidol was the antipsychotic medication that caused minor impact on the development of metabolic disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
A 53-year-old patient underwent a positron emission tomography/computed tomography with 2-fluoro-2-deoxy-d-glucose ((18)F-FDG PET/CT) in the suspicious of gastric tumor recurrence (mediastinal and abdominal lymph nodes). PET/CT identified only an area of (18)F-FDGuptake in the twelfth thoracic vertebrae. Unexpectedly, a bone scintigraphy revealed many "hot" spots changing the diagnosis (single metastasis versus plurimetastatic disease) and impacting on patient's management.
