Abstract
BACKGROUND The optimal management of patients taking oral anticoagulants who experience minor head injury (MHI) is unclear. The availability of validated protocols and reliable predictors of prognosis would be of great benefit. We investigated clinical factors as predictors of clinical outcomes and intracranial injury (ICI). METHODS We conducted a single-cohort, prospective, observational study in an ED. Our structured clinical pathway included a first head CT scan, 24 h observation and a second CT scan. The primary outcome was the occurrence of MHI-related death or re-admission to ED at day +30. The secondary outcome was the rate of delayed ICI (dICI), defined as second positive CT scan after a first negative CT scan. We assessed some clinical predictors derived from guidelines and clinical prediction rules as potential risk factors for the outcomes. RESULTS 450 patients with a negative first CT scan who underwent a second CT scan composed our 'study population'. The rate of the primary outcome was 4%. The rate of the secondary outcome was 4.7%. Upon univariate and multivariate analysis no statistically significant predictors for the outcomes were found. CONCLUSIONS Previous retrospective studies showed a lot of negative predictive factors for anticoagulated patients suffering a minor head injury. In our prospective study no clinical factors emerged as predictors of poor clinical outcomes and dICI. So, even if we confirmed a low rate of adverse outcomes, the best management of these patients in ED remains not so clear and future trials are needed.

Abstract
The present study was aimed at investigating DNA damage, micronuclei frequency and meta-nuclear alterations in buccal cells of workers involved in pigment-grade TiO2 production (15 exposed and 20 not-exposed). We also assessed associations of genotoxicity biomarkers with oxidative stress/inflammatory biomarkers in urine and exhaled breath condensate (EBC), as well as possible associations between biomarkers and reported respiratory symptoms. In spite of compliance with TiO2 Occupational Exposure Limits, results showed increased direct/oxidative DNA damage and micronuclei frequency in exposed workers. Genotoxicity parameters were associated with oxidative stress/inflammation biomarkers in urine and EBC, thus confirming that TiO2 exposure can affect the oxidative balance. Workers with higher genotoxic/oxidative stress biomarkers levels reported early respiratory symptoms suggesting that molecular alterations can be predictive of early health dysfunctions. These findings suggest the need to assess early health impairment in health surveillance programs and to address properly safety issues in workplaces where TiO2 is handled.

Abstract
The Sonic Hedgehog (Hh) signal transduction pathway plays a critical role in many developmental processes and, when deregulated, may contribute to several cancers, including basal cell carcinoma, medulloblastoma, colorectal, prostate, and pancreatic cancer. In recent years, several Hh inhibitors have been developed, mainly acting on the Smo receptor. However, drug resistance due to Smo mutations or non-canonical Hh pathway activation highlights the need to identify further mechanisms of Hh pathway modulation. Among these, deacetylation of the Hh transcription factor Gli1 by the histone deacetylase HDAC1 increases Hh activity. On the other end, the KCASH family of oncosuppressors binds HDAC1, leading to its ubiquitination and subsequent proteasomal degradation, leaving Gli1 acetylated and not active. It was recently demonstrated that the potassium channel containing protein KCTD15 is able to interact with KCASH2 protein and stabilize it, enhancing its effect on HDAC1 and Hh pathway. KCTD15 and KCTD1 proteins share a high homology and are clustered in a specific KCTD subfamily. We characterize here KCTD1 role on the Hh pathway. Therefore, we demonstrated KCTD1 interaction with KCASH1 and KCASH2 proteins, and its role in their stabilization by reducing their ubiquitination and proteasome-mediated degradation. Consequently, KCTD1 expression reduces HDAC1 protein levels and Hh/Gli1 activity, inhibiting Hh dependent cell proliferation in Hh tumour cells. Furthermore, analysis of expression data on publicly available databases indicates that KCTD1 expression is reduced in Hh dependent MB samples, compared to normal cerebella, suggesting that KCTD1 may represent a new putative target for therapeutic approaches against Hh-dependent tumour.

Abstract
Asbestos cement materials (ACMs) are widespread in coastal environments as result of illegal dumping activities. This study focuses on the Taranto area (Italy) in the Mar Grande basin within the northern sector of the Ionian Sea. The complex history of dumping building materials containing high amounts of ACM into the coastal zone, and the erosion, transport and deposition in Marechiaro Bay is a serious environmental hazard. An interdisciplinary research methodology defines the temporal dumping succession, and the erosional processes and phases, the diffusion of ACM, the mineralogical characteristics, and existing physical status of the ACM. A multiscale investigation was conducted. Results show that from 1992 to 2000 a significant increment of dumping operations have occurred. The current cliff has been subject to erosion and redeposition phases, developing a new beach composed of these polluted man-made sediments. The findings persuade the local authorities to close the beach requiring remediation interventions.

Abstract
Obesity is the fifth leading cause of death worldwide. In mice and humans with obesity, the adipose organ undergoes remarkable morpho-functional alterations. The comprehension of the adipose organ function and organization is of paramount importance to understand its pathology and formulate future therapeutic strategies. In the present study, we performed anatomical dissections, magnetic resonance imaging, computed axial tomography and histological and immunohistochemical assessments of humans and mouse adipose tissues. We demonstrate that most of the two types of adipose tissues (white, WAT and brown, BAT) form a large unitary structure fulfilling all the requirements necessary to be considered as a true organ in both species. A detailed analysis of the gross anatomy of mouse adipose organs in different pathophysiological conditions (normal, cold, pregnancy, obesity) shows that the organ consists of a unitary structure composed of different tissues: WAT, BAT, and glands (pregnancy). Data from autoptic dissection of 8 cadavers, 2 females and 6 males (Age: 37.5 ± 9.7, BMI: 23 ± 2.7 kg/m2) and from detailed digital dissection of 4 digitalized cadavers, 2 females and 2 males (Age: 39 ± 14.2 years, BMI: 22.8 ± 4.3 kg/m2) confirmed the mixed (WAT and BAT) composition and the unitary structure of the adipose organ also in humans. Considering the remarkable endocrine roles of WAT and BAT, the definition of the endocrine adipose organ would be even more appropriate in mice and humans.

Abstract
In vitro flow-induced mechanical stimulation of developing bone tissue constructs has been shown to favor mineral deposition in scaffolds seeded with cells directly exposed to the fluid flow. However, the effect of fluid dynamic parameters, such as shear stress (SS), within 3D bioprinted constructs is still unclear. Thus, this study aimed at correlating the SS levels and the mineral deposition in 3D bioprinted constructs, evaluating the possible dampening effect of the hydrogel. Human mesenchymal stem cells (hMSCs) were embedded in 3D bioprinted porous structures made of alginate and gelatin. 3D bioprinted constructs were cultured in an osteogenic medium assessing the influence of different flow rates (0, 0.7 and 7 ml/min) on calcium and collagen deposition through histology, and bone volume (BV) through micro-computed tomography. Uniform distribution of calcium and collagen was observed in all groups. Nevertheless, BV significantly increased in perfused groups as compared to static control, ranging from 0.35±0.28 mm3, 11.90±8.74 mm3 and 25.81±5.02 mm3 at week 3 to 2.28±0.78 mm3, 22.55±2.45 mm3 and 46.05±5.95 mm3 at week 6 in static, 0.7 and 7 ml/min groups, respectively. SS values on construct fibers in the range 10-100 mPa in 7 ml/min samples were twice as high as those in 0.7 ml/min samples showing the same trend of BV. The obtained results suggest that it is necessary to enhance the flow-induced mechanical stimulation of cell-embedding hydrogels to increase the amount of mineral deposited by hMSCs, compared to what is generally reported for the development of in vitro bone constructs. STATEMENT OF SIGNIFICANCE: : Culture of 3D Bioprinted Bone Constructs Requires an Increased Fluid Dynamic Stimulation, In this study, we evaluated for the first time how the hydrogel structure dampens the effect of flow-induced mechanical stimulation during the culture of 3D bioprinted bone tissue constructs. By combining computational and experimental techniques we demonstrated that those shear stress thresholds generally considered for culturing cells seeded on scaffold surface, are no longer applicable when cells are embedded in 3D bioprinted constructs. Significantly, more bone volume was formed in constructs exposed to shear stress values generally considered as detrimental than in constructs exposed shear stress values generally considered as beneficial after 3 weeks and 6 weeks of dynamic culture using a perfusion bioreactor.

Abstract
BackgroundPatients with systemic autoimmune diseases (SADs) are often treated with drugs that interfere with the immune system and previous data showed a reduced seroconversion rate after anti-SARS-CoV2 vaccine in these subjects compared to healthy controls1. Administration of a booster dose of the vaccine could be particularly important in these patients, but data available to date are still scarce.ObjectivesTo evaluate the antibody response to the booster dose of mRNA SARS-CoV2 vaccine in patients with SADs and to compare it to the response after completion of the first vaccination course. Secondly, to find possible correlations between a low antibody titre and patients’ clinical features, with special regard to ongoing immunosuppressive therapies.MethodsConsecutive patients with an established diagnosis of SADs undergoing SARS-CoV2 vaccine were prospectively enrolled from January 2021; among them, we selected the patients who received the third vaccination dose between September and December 2021. Demographic and clinical data were collected at enrolment (sex, age, diagnosis, disease duration, ongoing therapies, previous SARS-CoV2 infection, presence of hypogammaglobulinemia); the last three elements were reassessed at each follow-up visit. Blood samples were collected 4 weeks both after the second (W4a) and the third (W4b) dose of the vaccine; a minority of patients was also tested 12 weeks after the second dose (W12). IgG antibodies to SARS-CoV2 receptor-binding domain (RBD) and neutralizing antibodies inhibiting the interaction between RBD and angiotensin converting enzyme 2 were evaluated. IgG anti-RBD were detected by solid phase assay on plates coated with recombinant RBD, while neutralising antibodies by using the kit SPIA (Spike Protein Inhibition Assay). Cut-off values were defined as the 97.5th percentile of a pre-vaccine healthy population. Statistical analysis was performed using IBM SPSS Statistics 20 and GraphPad Prism statistical packages. P values <0.05 were considered significant.ResultsForty-five patients (95.6% female; mean age ±SD 55.6±14.1 years; mean disease duration 12.9±10.6 years) were enrolled. Diagnosis was in most cases connective tissue disease (31/45, 68.9%), followed by inflammatory arthritis (11/45, 24.4%) and systemic vasculitis (3/45, 6.7%). Two patients (4.4%) had a previous SARS-CoV2 infection and three had hypogammaglobulinemia (6.7%). At the time of the second dose, 18/45 patients were treated with glucocorticoids (GCs) [mean daily 6-methylprednisolone (6MP) dose 3.9 mg (min. 2, max. 14)], 17/45 with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and 12/45 with biologic DMARDs (bDMARDs). At the third dose administration, 19/45 patients were treated with GCs [mean daily 6MP dose 4.1 mg (min. 1.5, max. 10)], 18/45 with csDMARDs and 13/45 with bDMARDs. Anti-RBD IgG were positive in 42/45 patients (93.3%) at W4a, in 16/18 (88.9%) at W12 and in 42/45 (93.3%) at W4b. Neutralizing antibodies were present in 38/45 patients (84.4%) at W4a, in 14/18 (77.8%) at W12 and in 42/45 (93.3%) at W4b. Both anti-RBD IgG titers and neutralizing antibody titers significantly increased after the third dose if compared to W4a (p<0.0001 both) (Figure 1). Interestingly, of the 7 patients who had not developed an adequate neutralizing antibody response after the first vaccination course, 5 mounted an adequate titer after the booster. Two non-responder patients were both on combination therapy (one with low dose of GCs plus mycophenolate mofetil, the other with methotrexate and infliximab).ConclusionOur data suggest that in patients with SADs there is a decline in the antibody titers developed after COVID-19 vaccination, however the booster dose is effective in restoring an adequate antibody titre. These data consolidate the importance of a booster dose of COVID-19 vaccination in patients with SADs to aid in the generation of an immune response.References[1]Jena A et al.

Abstract
BackgroundGrowing evidence from in vitro and clinical studies have highlighted important similarities between severe COVID-19 and rapidly progressive interstitial lung diseases (ILD) occurring in systemic autoimmune disorders. These data supported the use of anti-rheumatic drugs, baricitinib and glucocorticoids, for the treatment of COVID-19 pneumonia.ObjectivesTo compare mortality rate and inflammatory response in critically ill COVID-19 patients treated with either a “rheumatologic approach” based on baricitinib plus pulse steroids (BPS) or with a “conventional approach” (Standard of Care, SoC).MethodsIn this retrospective study, we enrolled patients admitted to the Intensive Care Unit (ICU) with CT-proven SARS-CoV2 pneumonia, from September 2020 to April 2021. Demographic, laboratory, and clinical data were collected at the admission to ICU and after one week of treatment. SoC included dexamethasone 6 to 8 mg daily plus remdesivir (+/- antibiotics and hydroxychloroquine); BPS approach was based on baricitinib 4 mg daily for 10-14 days plus 6-methylprednisolone pulses (250-500 mg) for three consecutive days followed by rapid tapering. The primary endpoint was the intra-ICU mortality rate; the secondary endpoint was the change in inflammatory biomarkers at week 1 after treatment.ResultsWe enrolled a total of 210 consecutive patients with SARS-CoV2 pneumonia (male 61.4%, mean age 66.6 ± 10.9 years); 137/210 (male 59.8%, mean age 66.3 ± 11.9 years) were treated with SoC and 73/210 (male 64.3%, mean age 67.3 ± 8.8 years) with BPS.At admission in ICU, all patients presented lag time from the first symptom of SARS-CoV2 infection ≤ 10 days, laboratory biomarkers’ alterations suggestive of hyper-inflammatory response (CRP 10.8 ± 11.9 mg/dL, ferritin 1238 ± 1005 µg/L, fibrinogen 575 ± 173 mg/dL, LDH 385 ± 152 U/L) and severe respiratory failure, requiring non-invasive or invasive ventilatory support. Lung-CT pattern showed multiple and diffuse areas of ground glass opacities, septal thickening, and/or consolidation.No statistically significant differences were found between SoC and BPS groups in terms of demographic, laboratory, and clinical features at enrolment.59/210 (28.1%) patients died during ICU hospitalization (mean ICU length of stay 14.6 ± 9.6 days). Mortality rate in the BPS group (13/73, 17.8%) resulted significantly lower compared to that in the SoC group (46/137, 33.6%) (p= 0.016). Furthermore, patients in the BPS group had significantly lower levels of CRP (BPS=1.9 ± 2.8 vs SoC 6.1 ± 7.3, p<0.001) and fibrinogen (BPS=335 ± 108 vs SoC 453 ± 172, p<0.001) at one week after the start of treatment.ConclusionOur real-life experience, in an ICU setting, showed that baricitinib and pulse steroids combination was associated with a lower mortality rate paralleled by a prompt reduction of inflammatory biomarkers. These results shed new light on the possible usefulness of baricitinib for the treatment of rapidly progressive ILD in patients with systemic autoimmunity and hyper-inflammation.Disclosure of InterestsNone declared

Abstract
BackgroundSince the COVID-19 vaccination campaign was launched all over Europe, there has been general agreement on how benefits of SARS-CoV2 vaccines outweigh the risks in patients with rare connective tissue diseases (rCTDs). Yet, there is still limited evidence regarding safety and efficacy of such vaccines in these patients, especially in the long-term. For this reason, in the framework of ERN-ReCONNET, an observational long-term study (VACCINATE) was designed in order to explore the long-term outcome of COVID-19 vaccination in rCTDs patients. The consent form was developed thanks to the involvement of the ERN ReCONNET ePAG Advocates (European Patients Advocacy Group).ObjectivesTo evaluate the safety profile of COVID-19 vaccination in rCTDs patients and the potential impact on disease activity. Primary endpoints were the prevalence of adverse events (AEs) and of disease exacerbations post-vaccination. Secondary endpoints were the proportion of serious adverse events (SAEs) and adverse events of special interest for COVID-19 (adapted from https://brightoncollaboration.us/wp-content/uploads/2021/01/SO2_D2.1.2_V1.2_COVID-19_AESI-update-23Dec2020-review_final.pdf)MethodsThe first ad-interim analysis of the VACCINATE study involved 9 ERN-ReCONNET Network centres. Patients over 18 years of age with a known rCTD and who received vaccine against COVID-19 were eligible for recruitment. Demographic data and diagnoses were collected at the time of enrolment, while the appearance of AEs and potential disease exacerbations were monitored after one week from each vaccination dose, and then after 4, 12 and 24 weeks from the second dose. A disease exacerbation was defined as at least one of the following: new manifestations attributable to disease activity, hospitalization, increase in PGA from previous evaluation, addition of corticosteroids or immunosuppressants.ResultsA cohort of 300 patients (261 females, mean age 52, range 18-85) was recruited. Systemic lupus erythematosus (44%) and systemic sclerosis (16%) were the most frequent diagnoses, followed by Sjogren’s syndrome (SS,12%), idiopathic inflammatory myositis (IMM,10%), undifferentiated connective tissue disease (UCTD,8%), mixed connective tissue disease (MCTD,4%), Ehlers-Danlos’s syndrome (EDS,4%), antiphospholipid syndrome (APS,2%). AEs appearing 7 days after the first and second doses were reported in 93 (31%) and 96 (32%) patients respectively, mainly represented by fatigue, injection site reaction, headache, fever and myalgia. Otitis, urticaria, Herpes Simplex-related rash, stomatitis, migraine with aura, vertigo, tinnitus and sleepiness were reported with very low frequency. Less than 2% of patients experienced AEs within 24 weeks from the second dose. No SAEs or AEs of special interest were observed in the study period. There were 25 disease exacerbations (8%), 7 of which severe. The highest number of exacerbations was observed after 4 weeks from the second dose (12 within week 4, 6 within week 12 and 7 within week 24). Disease exacerbation was most frequent in patients with EDS (33%) and MCTD (25%).ConclusionThis preliminary analysis shows that COVID-19 vaccination is safe in rCTDs patients. AEs appear most often early after vaccination and are usually mild. Disease exacerbations are not frequent, but can be potentially severe and tend to occur most frequently within the first month after vaccination. Exacerbations can also occur 3-6 months after vaccination, although a causal relationship with the vaccination remains to be established. Our present data underline the importance of long-term observational studies.Table 1.AEs and disease exacerbations per diseaseDiagnosisPatients enrolled (%) (n=300)EAs after 1st and 2nd dose (%)Exacerbations (%)APS25714EDS45033IIM10527MCTD44225SS12598SLE44698SSC16492UCTD850-AcknowledgementsVACCINATE is a study promoted by the European Reference Network on rare and complex connective tissue diseases, ERN ReCONNET.

Abstract
This study aims to quantify antibiotic consumption for suspected respiratory tract superinfections in COVID-19 patients, while investigating the associated drivers of antibiotic prescribing in light of the current signs of antibiotic overuse. Adult patients with a positive COVID-19 diagnosis admitted to a Belgian 721-bed university hospital were analyzed retrospectively (March 11th-May 4th, 2020), excluding short-term admissions (< 24 h). Antibiotic prescriptions were analyzed and quantified, using Defined Daily Doses (DDD) per admission and per 100 bed days. Possible drivers of antibiotic prescribing were identified by means of mixed effects logistic modelling analysis with backwards selection. Of all included admissions (n = 429), 39% (n = 171) were prescribed antibiotics for (presumed) respiratory tract superinfection (3.6 DDD/admission; 31.5 DDD/100 bed days). Consumption of beta-lactamase inhibitor-penicillin combinations was the highest (2.55 DDD/admission; 23.3 DDD/100 bed days). Four drivers were identified: fever on admission (OR 2.97; 95% CI 1.42-6.22), lower SpO2/FiO2 ratio on admission (OR 0.96; 95% CI 0.92-0.99), underlying pulmonary disease (OR 3.04; 95% CI 1.12-8.27) and longer hospital stay (OR 1.09; 95% CI 1.03-1.16). We present detailed quantitative antibiotic data for presumed respiratory tract superinfections in hospitalized COVID-19 patients. In addition to knowledge on antibiotic consumption, we hope antimicrobial stewardship programs will be able to use the drivers identified in this study to optimize their interventions in COVID-19 wards.

Abstract
BACKGROUND Published reports on tocilizumab in COVID-19 pneumonitis show conflicting results due to weak designs or heterogeneity in critical methodological issues. METHODS This open-label trial, structured according to Simon's optimal design, aims to identify factors predicting which patients could benefit from anti-IL6 strategies and to enhance the design of unequivocal and reliable future randomized trials. A total of 46 patients with COVID-19 pneumonia needing of oxygen therapy to maintain SO2 > 93% and with recent worsening of lung function received a single infusion of tocilizumab. Clinical and biological markers were measured to test their predictive values. Primary end point was early and sustained clinical response. RESULTS Twenty-one patients fulfilled pre-defined response criteria. Lower levels of IL-6 at 24 h after tocilizumab infusion (P = 0.049) and higher baseline values of PaO2/FiO2 (P = 0.008) predicted a favourable response. CONCLUSIONS Objective clinical response rate overcame the pre-defined threshold of 30%. Efficacy of tocilizumab to improve respiratory function in patients selected according to our inclusion criteria warrants investigations in randomized trials.

Abstract
Plant pathogenic fungi colonizing living plant tissue secrete a cocktail of effector proteins to suppress plant immunity and reprogramme host cells. Although many of these effectors function inside host cells, delivery systems used by pathogenic bacteria to translocate effectors into host cells have not been detected in fungi. Here, we show that five unrelated effectors and two membrane proteins from Ustilago maydis, a biotrophic fungus causing smut disease in corn, form a stable protein complex. All seven genes appear co-regulated and are only expressed during colonization. Single mutants arrest in the epidermal layer, fail to suppress host defence responses and fail to induce non-host resistance, two reactions that likely depend on translocated effectors. The complex is anchored in the fungal membrane, protrudes into host cells and likely contacts channel-forming plant plasma membrane proteins. Constitutive expression of all seven complex members resulted in a surface-exposed form in cultured U. maydis cells. As orthologues of the complex-forming proteins are conserved in smut fungi, the complex may become an interesting fungicide target.

Abstract
Results Road tunnel construction workers revealed higher frequencies of cells with genotoxic damage (i.e., MN and NBUD). MN and NBUD resulted to be Poisson distributed and counts of these genotoxicity biomarkers were then analysed by Poisson regression. The frequency ratio (FR) for MN was 1.31 (95% CI: 0.84-2.04), with an increase in the exposed subjects; this finding, though indicating a higher genotoxic risk in the exposed subjects, did not reach statistical significance. On the other hand, the FR for NBUD was 3.49 (95% CI: 1.86-6.56), with a statistically significant increased risk of chromosomal damage. Even the frequencies of binucleated cells (a marker of cell proliferation) and pyknotic cells (a cell death biomarker) were significantly higher in tunnel workers. Introduction Tunnel construction workers are exposed to complex mixtures of toxic agents, some of which are known to be genotoxic. The aim of this study was to evaluate the genotoxic risk in this occupational setting by comparing tunnel workers with a control group for frequencies of nuclear aberrations in oral exfoliated cells. Methods To evaluate the genotoxic effects of tunnel air pollutants, we conducted a cross-sectional, molecular epidemiological study (35 tunnel workers and 35 healthy controls) using the buccal micronucleus cytome assay. A questionnaire was administered to obtain information about demographic variables, lifestyle, dietary habits, anthropometric data, and occupational history. Buccal mucosa cells were collected by scraping the buccal mucosa with a small-headed toothbrush. Coded slides were examined blind by trained scorers for micronuclei (MN), nuclear buds (NBUD), and other nuclear abnormalities. Conclusions Our observations provide further knowledge and understanding of the occupational hazards of tunnel workers and confirm the complexity of effects (cytotoxic and genotoxic) probably induced by fumes and dust produced in underground operations.

Abstract
Abstract
Aim
According to the World Health Organization (WHO), 40 million children aged < 5 and 131 million of children aged 5-9 are overweight or obese. Growing evidence is focusing on the association between number of hours spent watching television (TV) and children's food behaviour. Our aim was to assess the amount of TV food marketing targeted to Italian children, and to qualitatively analyse the ads.
Methods
The 5 most viewed TV channels were selected and recorded for 20 days (non-consecutive, both week and week-end days) and analysed through the WHO's tool to asses food -beverage multimedia marketing targeted to children. The analysed exposure variables were: type of product, viewing time, channel's target and broadcasting company (for all types of ads), duration of each food ad, type of programme, and target of the advertised product (only for food and beverage). Power of persuasion variables were assessed only for food marketing. Lastly, for each food product showed, the food category and if it was a core vs non-core product was assessed. Differences between groups were assessed using the chi-square test and t-test.
Results
During 320 hours of broadcasting TV, a total of 9,069 ads were identified, (51.7 hours). Food products were the second most frequently advertised (19.4%). On average, 5.4 food ads were displayed during non-peak viewing time/hour (6 during peak). The time slot of 3 pm had the highest rate of food ads (23.8%). Channels targeted to the general public had a higher rate of food ads compared to channels targeted to children (p = 0.000). Private channels transmitted a higher number of food ads compared to public channels (p = 0.000). Humour was the most frequently persuasive technique used in food ads and in ads targeted to whole population (14.3%).
Conclusions
Children usually watch TV programs that have a high rate of food ads, mainly promoting unhealthy products with captivating techniques. Legislators should advocate for a healthier food marketing.
Key messages
Children are exposed to a high amount of TV food commercials daily. Food marketing should be strictly regulated in accordance with the WHO Nutrient Profile model.

Abstract
INTRODUCTION Breast cancer is the most common cancer in women worldwide, for which the survival rate is increasing over time. Growing evidence are showing that the effect of lifestyle could have the same weight of the effect of the usual clinical-pathological risk factors on survival rate. The DianaWeb study responds to the pressing request of patients diagnosed with breast cancer to know the most advanced point of scientific research on the prevention of recurrences, to have a virtual space to meet, where to receive advice and practical information for the daily management the lifestyle change. DianaWeb is a community-based participatory research, dedicated to breast cancer patients, aimed to monitor lifestyle, provide them tips to encourage sustainable lifestyle changes, and to analyze clinical outcomes. In order to achieve these aims, DianaWeb uses a specific interactive website (http://www.dianaweb.org/). METHODS The web architecture has been designed essential and light, with a rigorous implantation that brings the figure of the woman to the center. In order to humanized the project the acronym used to identify the study was Diana (Diet and Androgens), a classical female name, who was illustrated as a female avatar, aimed to symbolize all women. The graphical interface was developed using seven pastel tones colors, which become a fundamental elements of the layout, such as frame, navigation menu, and separation interspaces. RESULTS The project started in 2015, and in 4 days the web site was visited by more than 1000 people. A total of 2823 persons enrolled in the study, but 2182 did not send the full documentations, 61 persons abandoned the study, 641 timely answered to the questionnaires. CONCLUSIONS The high number of participants' interaction within the web page, confirmed the high usability of the web page and the great interest of patients. Prevention of breast cancer recurrences with low cost technologies, easily available to everybody, is a priority for both public health and public finances.

Abstract
Abstract
Background
Trastuzumab (TZ) has a primary role in the therapy of HER-2 positive breast cancer but has potential negative effect on left ventricular (LV) function that define cardiotoxicity (CT). Decrease in LV longitudinal strain (GLS) and in left atrial (LA) function observed by peak atrial longitudinal strain (PALS), besides LA remodeling, has already been described as predictors of TZ-related CT. However these parameters haven’t been observed together and regardless of CT.
Purpose
to describe overall atrial and ventricular morpho-functional variations during TZ therapy.
Methods
HER-2 positive metastasis-free breast cancer patientsreferring to our Echo-lab were prospectively recruited. Trans-thoracic echocardiography was performed before starting TZ and every 3 up to 12 months. LV volumes and ejection fraction (LVEF), indexed LA volume (LAVI), LA deformation parameters, and multiple diastolic parameters were collected. 2D-Speckle tracking analysis was performed at baseline and at each examination using Philips’ QLAB software.
Results
Eligible patients were 64. 53 of these (82,8%) had a complete follow-up at 12 months and were included in the analysis. 42 patients (79,3%) were treated with both TZ and anthracyclines. During follow-up CT occurred in 7 patients (10,9%). Mean baseline parameters were: age 54 ± 13 years,LVEF 63,3 ±3,2%, GLS -21,2 ± 2,1%, LAVI 24,4 ±6,9 ml/mq, peak atrial contraction strain (PACS) 22,9 ±6,5%, PALS 51,1 ± 11,5%. Deformation analysis was feasible in 95% of patients. None of the echocardiographic parameters regarding diastolic function and LV volumes showed significant variations.
Analyzing overall populations data during the 1 year of follow-up, we reported a decrease trend of GLS (p for time <0.0001) with an early drop during the first 6 months of TZ therapy with a subsequent "plateau" phase, and a reductionof LVEFover time (p for time <0.0001) with a continuous gradual decreasefor the whole follow-up (but still within the normal value span). On top LA functional parameters showed a decreasing trend: PALS (p for time <0.0001) and PACS (p for time <0.0001) showed both decrease trend since the first months of therapy, lasting for the entire follow-up. Also we reported a notable LAVI dilation during the first 6 months of TZ therapy (p for time <0.0001) followed by a plateau phase, and combining LAVI and PALS (LAVI/PALS) we noted an increase trend (p for time <0.0001). These data are showed in Figure I.
Conclusions
Our results suggest that deformation analysis is useful to study LV and LA functional remodeling during TZ therapy. Actual recommendations for the identification of CT are based upon a joint evaluation of LVEF and GLS, but our study show significant variations of other morpho-functional parameters regardless of CT. These changes could be used as indicators of subclinical damage involving the entire heart and the analysis of different deformation indexes could improve the early detection of CT.

Abstract
Abstract
Background
Children are at high risk of suffering health consequences of air pollution and childhood exposure can increase the risk of developing chronic diseases in adulthood. The MAPEC_LIFE project, funded by EU Life+ Programme (LIFE12 ENV/IT/000614), aimed to evaluate the association between air pollution exposure and biomarkers of early effect in children and to propose guidance for implementing environmental policies.
Methods
The study was carried out on 6-8-year-old children. Micronucleus (MN) frequency was investigated in buccal cells of children and its association with air pollution exposure was assessed applying multiple Poisson regression mixed models, including socio-demographic and lifestyle factors as confounders. We also dichotomize air pollutants concentration according to the EU Ambient Air Quality Directives and WHO Air Quality Guidelines in all Poisson regression models to assess their risk predictive capacity.
Results
The project involved 1149 children providing buccal cells in winter and spring. 2139 biological samples were included in the analysis (1093 collected in winter, 1046 in spring). The analysis of the association between MN frequency and air quality parameters found positive associations for PM10, PM2.5, benzene, SO2 and ozone. Considering EU Directives, an association was found between MN frequency and PM10 exposure higher than the annual limit value, with an increase of the risk of 17.9% (95%CIs: 0.6-38.1%). Considering WHO Guidelines, the exposures to levels of PM10, benzene and BaP higher than the annual limits were associated with MN frequency, with a risk increase of 22.5%, 27.8% and 59.8% (95%CIs: 3.9-44.3%, 3.8-57.3%, 21.0-111.1%), respectively.
Conclusions
The analyses conducted showed an association between MN frequency in buccal cells of children and levels of some air pollutants, even at concentration below EU and WHO thresholds, which hence seemed to be insufficient for protecting children from this type of damage.
Key messages
Air pollution exposure induced chromosomal damage in buccal cells of children, even at concentration below the law limits. Early biological damage detected might be predictive of the occurrence of future harmful effects in humans, at a population level.

Abstract
Wastewater reuse provides valuable solutions to solve the societal challenges of decreasing availability and limiting access to secure water resources. The present study quantifies the environmental performance of nectarine orchards irrigation using treated municipal wastewater (TMW) and surface water using a unique dataset based on field experimental data. Climate change, toxicity (for human and freshwater), eutrophication (marine and freshwater) and acidification impacts were analysed using the impact assessment method suggested by the International Reference Life Cycle Data System (ILCD). The water footprint associated to the life cycles of each system has been estimated using the Available WAter REmaining (AWARE) method. Monte Carlo simulation was used to assess data uncertainty. The irrigation of nectarine orchards using TMW performs better than the irrigation using surface water for eutrophication impact categories. Compared with surface water resources, the potential impacts of TMW reuse in agriculture on climate change and toxicity are affected by the wastewater treatment phase (WWT). Only eutrophication and acidification burdens are generated by in-field substitution of surface water with TMW. Considering human and ecosystem water demand, the irrigation with TMW increases water consumption of 19.12 m3 per kg of nectarine produced. Whereas, it shows a positive contribution to water stress (-0.19 m3) if only human water demand is considered. This study provides important results that allow for a better understanding of the potential environmental consequences of TMW reuse in agriculture. It suggests that embracing the type of WWTs, the replacement of fertilizers, the effects on water scarcity and ecosystem quality might be useful to redefine water reuse regulations and increase public acceptance for the reuse of TMW in agriculture. Moreover, this study reveals the need for developing consensus and standardized guidance for life cycle analysis of water reuse applications.

Abstract
Epidemiological studies report strong association between mood disorders and tobacco addiction. This high comorbidity requires adequate treatment but the underlying mechanisms are unknown. We demonstrate that nicotine exposure, independent of drug withdrawal effects, increases stress sensitivity, a major risk factor in mood disorders. Nicotine and stress concur to induce long-lasting cellular adaptations within the dopamine (DA) system. This interplay is underpinned by marked remodeling of nicotinic systems, causing increased ventral tegmental area (VTA) DA neurons' activity and stress-related behaviors, such as social aversion. Blocking β2 or α7 nicotinic acetylcholine receptors (nAChRs) prevents, respectively, the development and the expression of social stress-induced neuroadaptations; conversely, facilitating α7 nAChRs activation specifically in the VTA promotes stress-induced cellular and behavioral maladaptations. Our work unravels a complex nicotine-stress bidirectional interplay and identifies α7 nAChRs as a promising therapeutic target for stress-related psychiatric disorders.

Abstract
To cause disease in maize, the biotrophic fungus Ustilago maydis secretes a large arsenal of effector proteins. Here, we functionally characterize the repetitive effector Rsp3 (repetitive secreted protein 3), which shows length polymorphisms in field isolates and is highly expressed during biotrophic stages. Rsp3 is required for virulence and anthocyanin accumulation. During biotrophic growth, Rsp3 decorates the hyphal surface and interacts with at least two secreted maize DUF26-domain family proteins (designated AFP1 and AFP2). AFP1 binds mannose and displays antifungal activity against the rsp3 mutant but not against a strain constitutively expressing rsp3. Maize plants silenced for AFP1 and AFP2 partially rescue the virulence defect of rsp3 mutants, suggesting that blocking the antifungal activity of AFP1 and AFP2 by the Rsp3 effector is an important virulence function. Rsp3 orthologs are present in all sequenced smut fungi, and the ortholog from Sporisorium reilianum can complement the rsp3 mutant of U. maydis, suggesting a novel widespread fungal protection mechanism. The fungus Ustilago maydis secretes many effector proteins to cause disease in maize. Here, Ma et al. show that the repetitive effector Rsp3 is required for virulence by inhibiting the antifungal activity of two mannose-binding proteins that are secreted by the plant cells.

Abstract
To define the prevalence of non-A, non-B hepatitis, antibodies to HCV were detected in 193 patients on renal replacement therapy (52 transplant and 141 hemodialysis patients) and in 50 staff members of a Nephrology Department. Unequivocal seroconversion was documented in 5 transplant (9.6%) and in 26 dialysis patients (18.4%). In the dialysis population, the prevalence of anti-HCV antibodies was evaluated in patients grouped according to the number of blood transfusions and to the different sections of dialytic treatment. The most striking findings were the marked differences in the prevalence of anti-HCV antibodies among patients treated in different sections (from 0% to 70%), and the presence of a significant increase in alanine-amino-transferase (ALT) concentrations in 14 anti-HCV negative patients. The results suggest that the diffusion of non-A, non-B hepatitis is mainly transfusion-related, with the possibility of significant environmental diffusion related to the violation of infection-control measures. The current immunoassay is probably unable to detect the actual frequency of the infection.

Abstract
Muscle fibrosis represents the end stage consequence of different diseases, among which muscular dystrophies, leading to severe impairment of muscle functions. Muscle fibrosis involves the production of several growth factors, cytokines and proteolytic enzymes and is strictly associated to inflammatory processes. Moreover, fibrosis causes profound changes in tissue properties, including increased stiffness and density, lower pH and oxygenation. Up to now, there is no therapeutic approach able to counteract the fibrotic process and treatments directed against muscle pathologies are severely impaired by the harsh conditions of the fibrotic environment. The design of new therapeutics thus need innovative tools mimicking the obstacles posed by the fibrotic environment to their delivery. This review will critically discuss the role of in vivo and 3D in vitro models in this context and the characteristics that an ideal model should possess to help the translation from bench to bedside of new candidate anti-fibrotic agents.

Abstract
BACKGROUND In Crohn's disease (CD) patients, stress is believed to influence symptoms generation. Stress may act via central nervous system pathways to affect visceral sensitivity and motility thus exacerbating gastrointestinal symptoms. The neural substrate underpinning these mechanisms needs to be investigated in CD. We conducted an explorative functional magnetic resonance imaging (fMRI) study in order to investigate potential differences in the brain stress response in CD patients compared to controls. METHODS 17 CD patients and 17 healthy controls underwent a fMRI scan while performing a stressful task consisting in a Stroop color-word interference task designed to induce mental stress in the fMRI environment. KEY RESULTS Compared to controls, in CD patients the stress task elicited greater blood oxygen level dependent (BOLD) signals in the midcingulate cortex (MCC). CONCLUSIONS & INFERENCES The MCC integrate "high" emotional processes with afferent sensory information ascending from the gut. In light of these integrative functions, the stress-evoked MCC hyperactivity in CD patients might represent a plausible neural substrate for the association between stress and symptomatic disease. The MCC dysfunction might be involved in mechanisms of central disinhibition of nociceptive inputs leading to amplify the visceral sensitivity. Finally, the stress-evoked MCC hyperactivity might affect the regulation of intestinal motility resulting in exacerbation of disease symptoms and the autonomic and neuroendocrine regulation of inflammation resulting in enhanced inflammatory activity.

Abstract
AIMS The study is a part of the "Active surveillance of adverse events following HPV vaccination" project conducted in order to actively register all common adverse events in girls 9-26 years after anti-HPV vaccination. METHODS It is a multicenter cohort study which included 12 Regions and 87 local health authorities, coordinated by the National Centre for Epidemiology, Surveillance and Health Promotion (CNESPS) ISS. We included all adolescents, 12 years old, actively contacted for HPV vaccination, as well as all women aged 9-26 years who recived, in the period under review, the same vaccination at the local health authorities in Spoleto. RESULT Out of 147 girls enrolled in the program, only 102 have reported the diary filled after the first vaccine dose, 62 and 88 respectively after the second and third dose. The filled diaries shown that adverse events, if any, have occurred almost exclusively during the first 5 days of vaccination, with a strong prevalence of local reactions (erythema, pain and swelling at the injection site) followed by headache and muscles pain. CONCLUSION Even though the results show a high number of reported adverse events, mainly due to the detection method (active surveillance), they are mild or moderate in almost all the cases. This is in line with that seen in previous trials.

Abstract
In bio-imaging by electron microscopy, damage of the sample and limited contrast are the two main hurdles for reaching high image quality. We extend a new preparation method based on nanofabrication and super-hydrophobicity to the imaging and structural studies of nucleic acids, nucleic acid-protein complexes (DNA/Rad51 repair protein complex) and neuronal ion channels (gap-junction, K+ and GABAA channels) as paradigms of biological significance and increasing complexity. The preparation method is based on the liquid phase and is compatible with physiological conditions. Only in the very last stage, samples are dried for TEM analysis. Conventional TEM and high-resolution TEM (HRTEM) were used to achieve a resolution of 3.3 and 1.5 Å, respectively. The EM dataset quality allows the determination of relevant structural and metrological information on the DNA structure, DNA-protein interactions and ion channels, allowing the identification of specific macromolecules and their structure.

Abstract
This case series demonstrates a potential new role for the use of intravenous (IV) acetaminophen. The authors reviewed two cases, whereby patients that developed intrapartum fever leading to fetal tachycardia were effectively treated with IV acetaminophen, leading to rapid reduction of maternal temperature and resolution of fetal tachycardia. Both patients had an uncomplicated vaginal delivery of healthy neonates. Intravenous acetaminophen, with its increased bioavailability and more rapid onset of action, may have benefit in the intrapartum setting by reducing adverse neonatal and maternal outcomes associated with febrile morbidity.

Abstract
BACKGROUND Pollen-food syndrome (PFS) is heterogeneous with regard to triggers, severity, natural history, comorbidities, and response to treatment. Our study aimed to classify different endotypes of PFS based on IgE sensitization to panallergens. METHODS We examined 1271 Italian children (age 4-18 years) with seasonal allergic rhinoconjunctivitis (SAR). Foods triggering PFS were acquired by questionnaire. Skin prick tests were performed with commercial pollen extracts. IgE to panallergens Phl p 12 (profilin), Bet v 1 (PR-10), and Pru p 3 (nsLTP) were tested by ImmunoCAP FEIA. An unsupervised hierarchical agglomerative clustering method was applied within PFS population. RESULTS PFS was observed in 300/1271 children (24%). Cluster analysis identified five PFS endotypes linked to panallergen IgE sensitization: (i) cosensitization to ≥2 panallergens ('multi-panallergen PFS'); (ii-iv) sensitization to either profilin, or nsLTP, or PR-10 ('mono-panallergen PFS'); (v) no sensitization to panallergens ('no-panallergen PFS'). These endotypes showed peculiar characteristics: (i) 'multi-panallergen PFS': severe disease with frequent allergic comorbidities and multiple offending foods; (ii) 'profilin PFS': oral allergy syndrome (OAS) triggered by Cucurbitaceae; (iii) 'LTP PFS': living in Southern Italy, OAS triggered by hazelnut and peanut; (iv) 'PR-10 PFS': OAS triggered by Rosaceae; and (v) 'no-panallergen PFS': mild disease and OAS triggered by kiwifruit. CONCLUSIONS In a Mediterranean country characterized by multiple pollen exposures, PFS is a complex and frequent complication of childhood SAR, with five distinct endotypes marked by peculiar profiles of IgE sensitization to panallergens. Prospective studies in cohorts of patients with PFS are now required to test whether this novel classification may be useful for diagnostic and therapeutic purposes in the clinical practice.

Abstract
Large bone defects still represent a major burden in orthopedics, requiring bone-graft implantation to promote the bone repair. Along with autografts that currently represent the gold standard for complicated fracture repair, the bone tissue engineering offers a promising alternative strategy combining bone-graft substitutes with osteoprogenitor cells able to support the bone tissue ingrowth within the implant. Hence, the optimization of cell loading and distribution within osteoconductive scaffolds is mandatory to support a successful bone formation within the scaffold pores. With this purpose, we engineered constructs by seeding and culturing autologous, osteodifferentiated bone marrow mesenchymal stem cells within hydroxyapatite (HA)-based grafts by means of a perfusion bioreactor to enhance the in vivo implant-bone osseointegration in an ovine model. Specifically, we compared the engineered constructs in two different anatomical bone sites, tibia, and femur, compared with cell-free or static cell-loaded scaffolds. After 2 and 4 months, the bone formation and the scaffold osseointegration were assessed by micro-CT and histological analyses. The results demonstrated the capability of the acellular HA-based grafts to determine an implant-bone osseointegration similar to that of statically or dynamically cultured grafts. Our study demonstrated that the tibia is characterized by a lower bone repair capability compared to femur, in which the contribution of transplanted cells is not crucial to enhance the bone-implant osseointegration. Indeed, only in tibia, the dynamic cell-loaded implants performed slightly better than the cell-free or static cell-loaded grafts, indicating that this is a valid approach to sustain the bone deposition and osseointegration in disadvantaged anatomical sites.

Abstract
Tendon ruptures and/or large losses remain to be a great clinical challenge and often require full replacement of the damaged tissue. The use of auto- and allografts or engineered scaffolds is an established approach to restore severe tendon injuries. However, these grafts are commonly related to scarce biocompatibility, site morbidity, chronic inflammation and poor biomechanical properties. Recently, the decellularisation techniques of allo- or xenografts using specific detergents have been studied and have been found to generate biocompatible substitutes that resemble the native tissue. This study aims to identify a novel decellularisation protocol for large equine tendons that would produce an extracellular matrix scaffold suitable for the regeneration of injured tendons in humans. Specifically, equine tendons were treated either with tri (n-butyl) phosphate alone, or associated to multiple concentrations of peracetic acid (1, 3 and 5 %), which has never before been tested in vitro.Samples were then analysed by histology and with biochemical, biomechanical, and cytotoxicity tests. The best decellularisation protocol, resulting from these examinations, was selected and the chosen scaffold was re-seeded with murine fibroblasts. Resulting grafts were tested for cell viability, histologic analysis, DNA and collagen content. The results identified 1 % tri (n-butyl) phosphate combined with 3 % peracetic acid as the most suitable decellularised matrix in terms of biochemical and biomechanical properties. Moreover, the non-cytotoxic nature of the decellularised matrix allowed for good fibroblast reseeding, thus demonstrating a biocompatible matrix that will be suitable for tendon tissue engineering and hopefully as substitutes in severe tendon damages.

Abstract
We have recently characterized the central components of the three MAP kinase cascades present in Cryphonectria parasitica : the MEK genes cpkk1, cpkk2 and cpkk3. When we attempted to infect through anastomosis the three knock out strains with Cryphonectria hypovirus 1 (CHV1), only the deletion strain of Cpkk2, the yeast Ste7 homologue, involved in mating and filamentous growth, could not be infected. We then proceeded to attempt virus infection through transformation of Δcpkk2 protoplasts using an infectious cDNA clone able to establish virus infection through transformation. In this case, a very limited number of strains could be recovered as stable transformants compared to the efficiency of control transformations with plasmid carrying only the antibiotic marker. Furthermore, transformants carrying actively replicating virus could be isolated only if the selection marker Geneticin was used during the very initial selection process, and not maintained throughout the growth of the colonies. Moreover, Δcpkk2 isolates that maintained the virus lost Geneticin resistance. We therefore unveiled a specific negative interaction among virus infection, presence of Geneticin in the growth media, and lack of Cpkk2 MEK in the fungal host.

Abstract
AIM To evaluate the causes of Early Childhood Caries. STUDY DESIGN A statistical comparison of two groups of patients, aged between 3 and 6, and their parents, in the 3-year period 2013-2015 was performed. Two groups of patients were selected: 40 children with early childhood caries (ECC group) and 40 children with no decay (controls). Parents were asked to fill out a questionnaire on food habits, oral hygiene habits, fluoride prophylaxis and family history of caries. A dental visit of children and parents was performed (collection of dmft and DMFT index). The saliva features of the two groups of children (concentration of Streptococcus mutans, pH of the oral cavity and buffer capability of stimulated saliva) were examined by means of salivary tests. The distribution of the population was analysed and parametric and non-parametric tests for continuous and non-continuous variables, were used when appropriate. The statistical significance was set at p > 0.005. RESULTS AND STATISTICS The average age, gender and BMI index of children of the two groups was similar. The difference between the two groups is statistically significant for pH (p=0.000) and buffer capability (p=0.001). The DMFT index in the group of mothers of ECC children is higher compared to the mothers of controls (p=0.004). The comparison among the means, for the parameters connected to the consumption of fruit juice, tea, soft drinks, candies, use of pacifier dipped in sugar or honey and the length (in months) of consumption of candies show statistically significant differences (p>0.05). The pH is higher in those children (24) who never consumed fruit juice, tea, soft drinks before the information received (p<0.05). CONCLUSIONS Children developing Early Childhood Caries have a diet characterised by high free sugars intake. Diet and, in particular, the consumption of drinks containing free sugars is the most important factor in determining the onset of ECC, being able to affect the oral environment and, in particular, saliva. There is a relationship between maternal and child's oral health, with a DMFT higher in mothers of ECC subjects than in controls' mothers.

Abstract
Quantitative gene expression analysis is widely used to evaluate the expression of specific tissue markers. To obtain reliable data it is essential to select stable housekeeping genes whose expression is not influenced by the anatomical origin of cells or by the culture conditions. No studies have evaluated housekeeping gene stability in intervertebral disc (IVD) cells and only few studies using cartilaginous endplate (CEP) and articular cartilage (AC) cells are present in the literature. We analysed the stability of four candidate housekeeping genes (GAPDH, TBP, YWHAZ and RPL13A) in human cells isolated from nucleus pulposus (NP) and annulus fibrosus (AF), CEP and AC. Cell isolation, expansion, cryoconservation, and differentiation in 3D pellets were tested. GeNorm, NormFinder, BestKeeper tools and the comparative ΔCt method were used to evaluate housekeeping gene stability. In each cell population, TBP alone or combined with YWHAZ was identified as the best normaliser in both monolayer and 3D pellets. GAPDH was the best performer only for AC cells in monolayer. In most culture conditions considering groups of two or more cell types, TBP was the most stable and YWHAZ was the second choice. GAPDH was the best performer only in 3D pellets with factors for AC and AF combined with CEP cells. RPL13A was the most stable only for AF with CEP cells at isolation. Our findings will be useful to properly design the experimental set-up of studies involving IVD, CEP or AC cells in different culture conditions, in order to obtain accurate and high quality data from quantitative gene expression analysis.

Abstract
X-ray fluorescence probe for detection of foreign material inclusions on the inner surface of superconducting cavities has been developed and tested. The setup detects trace element content such as a few micrograms of impurities responsible for thermal breakdown phenomena limiting the cavity performance. The setup has been customized for the geometry of 1.3 GHz TESLA-type niobium cavities and focuses on the surface of equator area at around 103 mm from the centre axis of the cavities with around 20 mm detection spot. More precise localization of inclusions can be reconstructed by means of angular or lateral displacement of the cavity. Preliminary tests confirmed a very low detection limit for elements laying in the high efficiency spectrum zone (from 5 to 10 keV), and a high angular resolution allowing an accurate localization of defects within the equator surface.

Abstract
OBJECTIVE Synovitis with an increased presence of macrophages is observed in osteoarthritis (OA) and rheumatoid arthritis (RA). Given the important role of macrophages in arthritis, we investigated the influence of OA and RA synovial fluid (SF) on primary human monocytes (Mo), their lineage precursors. METHOD Adherent monocytes without any stimulation (Mo(-)) or stimulated with IFN-γ and TNF-α (Mo(IFN-γ/TNF-α)) or IL-4 (Mo(IL-4)) were exposed to SF from 6 donors without any known joint disease (SF-Ctrl), 10 OA donors (SF-OA), and 10 RA donors (SF-RA). The transcriptional expression of IL6, IL1B, TNFA, IL10, CCL18, CD206, and IL1RA was analyzed. RESULTS Mo(-) exposed to SF-RA had a lower expression of IL10 and a higher expression of IL1RA than when exposed to SF-Ctrl. Mo(IL-4) exposed to SF-RA had a lower expression of IL10 and CCL18 than when exposed to SF-Ctrl and Mo(IFN-γ/TNF-α) were not affected by SF-RA. Mo exposed to SF-OA also expressed less IL10, but only upon stimulation with IL-4, and expressed more IL1RA than when exposed to SF-Ctrl in any condition. CONCLUSION A lower expression of IL10 may be regarded as a response to less inflammatory conditions since IL10 expression is higher in response to IFN-γ/TNF-α stimulation, probably as a feedback mechanism. Therefore, the lower expression of IL10 and the higher expression of IL1RA in Mo exposed to arthritic than to non-arthritic SF suggest that arthritic SF is mainly reducing the inflammatory responses in Mo. This may mimic the response of monocytes/macrophages recruited to the joint, where feedback mechanisms counteract pro-inflammatory processes.
