Abstract
Background:Interstitial Lung Disease (ILD) is an extra-articular complication of rheumatoid arthritis (RA) that is associated with increased morbidity and mortality. Conventional disease-modifying drugs (DMARDs) such as methotrexate (MTX) have been implicated in the development and exacerbation of a pre-existing ILD.Objectives:The aim of our study was to check the influence of combined MTX treatment in patients with RA-ILD treated with abatacept (ABA).Methods:National multicentre retrospective registry of 263 patients with RA-ILD treated with ABA. RA was diagnosed according to the ACR classification criteria of 1987 or by the EULAR/ACR criteria of 2010. ILD was diagnosed by high resolution computed tomography (HRCT). In this study we have done a subanalysis of the 46 patients treated with ABA in combination with MTX (ABA+MTX) vs. 217 patients treated with ABA in monotherapy or in combination with other synthetic DMARDs. Efficacy was evaluated according to the following parameters: a) Dyspnoea (MMRC) considering variations ≥ 1; b) Lung function test (LFT) considering variations ≥ 10% in FVC and a variation of DLCO ≥ 10%; c) Imaging test (HRCT) d) DAS28 score e) prednisone dose. Variables were collected at the beginning of the study and at months 3, 6, 12 and then every 12 months until a maximum of 60 months.Results:263 patients with ILD associated with RA were included in the study with mean age 64.64±10 years. RF or CCPA were positive in 235 (89.4%) and 233 (88.6%) cases, respectively, with a mean follow-up of 22.7±19.7 months. Baseline characteristics of both groups are shown in table 1, while data obtained during evolution of this complication are presented in Figure 1.Conclusion:Despite the baseline differences of both groups, the good evolution in the ABA+MTX subgroup suggests that this therapeutic strategy can be a safe combination for patients with RA-ILD.ABA with MTX (n=46)ABA w/t MTX (n=217)PSex (F/M)28/18122/950.625Age (years)65.11±10.216.2±9.80.202RF/CCPA + (%)91.3/91.389.8/90.10.810Smoking or past smoking (%)47.855.10.417Follow-up (months)22.73±18.0022.3±20.850.916DAS28 at baseline4.08±1.514.61±1.470.056DAS28 at last visit3.00±1.463.13±1.310.642Prednisone at baseline, median (IQR) (mg)5 (5-7.5)7.75 (5-15)0.008*Prednisone at the end of study, median (IQR) (mg)5 (1-5)5 (5-7.5)0.032*DLCO at baseline (%)66.85±19.0465.43±18.210.823DLCO at the end of study (%)66.05±20.9565.17±19.720.831FVC at baseline (%)90.06±17.7785.40±21.560.164FVC at the end of study (%)90.58±15,4584.21±21.490.038*Disclosure of Interests:Carlos Fernández-Díaz Speakers bureau: Brystol Meyers Squibb, Santos Castañeda: None declared, Rafael Melero: None declared, J.

Abstract
Background:Although the MDA response and DAPSA remission are treatment objectives proposed by EULAR for a proper management of psoriatic arthritis (PsA), there is no clear consensus on which of the two is the most advisable in clinical practice. Some studies suggest that patients who reach a sustained MDA have less subclinical atherosclerosis, but whether the same applies to DAPSA remission is unknown at present.Objectives:To compare the frequency of subclinical atherosclerosis in patients with PsA that reach the MDA response versus those who achieve DAPSA remission.Methods:One hundred-forty consecutive patients with PsA (CASPAR criteria) treated with biological and non-biological systemic agents were included. SCORE risk charts were used to estimate cardiovascular risk (CVR). The presence of plaques and / or carotid intima-media thickness (cIMT) > 0.9 mm in carotid ultrasound defined subclinical atherosclerosis. These findings were analyzed in patients in MDA and in those in DAPSA remission.Results:According to the SCORE tables, 42.8%, 35.7% and 21.5%, had low, moderate and high-very high CVR, respectively. There was a linear association between cIMT values and the SCORE risk categories (p <0.0005). The best cut-off point to define a high CVR (by SCORE plus carotid plaques) corresponded to a cIMT > 0.63 mm, with an area under the ROC curve of 0.75 (0.66-0.82), sensitivity 85.7%, specificity 56.1% (Figure 1). Ninety-seven of the 140 patients (69.3%) were in MDA situation, while 60 (42.8%) were in DAPSA remission. The average value of the cIMT was 0.64 ± 0.12 mm. One in 4 patient had atheroma plaques, while 19 (13.6%) had a cIMT> 0.9 mm. There were no differences in cIMT values of patients with (0.66 ± 0.12 mm) and without (0.63 ± 0.12 mm) DAPSA remission. An identical percentage (25%) of patients with and without DAPSA remission had carotid atheroma plaques. On the other hand, there were differences between patients with (6.2%) and without (30.2%) MDA in terms of cIMT values > 0.9 mm, p <0.05. 32.6% of non-MDA and 23.7% of MDA patients had carotid plaques, p NS.Conclusion:Patients who achieve an MDA response show less subclinical atherosclerosis than those in DAPSA remission. These findings suggest that the MDA response better discriminates the presence of subclinical atherosclerosis, and therefore, it could be a more complete therapeutic target than DAPSA remission.Disclosure of Interests:None declared

Abstract
Background:Secukinumab is a human monoclonal antibody directed against IL-17A, approved for the treatment of psoriatic arthritis (PsA) and ankylosing spondylitis (AS). The safety profile of secukinumab was favourable in clinical studies, but there is still scarce evidence in clinical practice. Similarly, we currently have less data regarding the real survival of secukinumab compared to other biological therapies such as anti-TNF.Objectives:To analyze the retention rate and safety of secukinumab as well as the causes and factors associated with its survival in patients with ankylosing spondylitis and psoriatic arthritis in real clinical practice.Methods:we conducted a retrospective longitudinal observational multicenter study of all patients with PsA and Spondyloarthritis (SpA) who had received at least one dose of secukinumab. Adverse events and drug retention were considered the main variables. In addition, we collected variables predicting drug retention. We estimated the total adverse event rate, by severity and type of event, and drug retention (mean duration and retention at 6 months, 1 year and 2 years), all with 95% confidence intervals (95% CI). Survival was analyzed using Kaplan-Meier curves and predictive factors using Cox regression, with the Hazard Ratio (HR) as a measure of the association.Results:154 patients were included, 59 with PsA (38%) and 95 with SpA (62%), with a mean age of disease onset of 49 years (SD ± 11), being 55% men. The mean disease duration was 6.5 years (ICR 2-8). The median number of previous biologics was 2 (SD ± 1). Secukinumab was the first line of treatment in 13 patients (8%), the second line in 46 (30%), the third line in 54 (35%) and subsequent lines in 41 (27%). The median survival of secukinumab was 23 months (ICR 5-32), with a 1-year retention rate of 66% and a 2-year retention rate of 43%. The most frequent cause of discontinuation was inefficacy (59%) and the second one was adverse events (AE) (36%). Most patients who discontinued due to AEs (71%) did so during the first 6 months of treatment. Only 2 major cardiovascular events were collected, and 2 cases of Crohn’s disease occurred during the exposure. The factors identified as predictors of survival for secukinumab were: duration of disease (HR 0.96, 95% CI 0.93-0.99 p=0.012), number of previous biologics (HR 1.18, 95% CI 1.04-1.34 p=0.011), male gender (HR 0.63, 95% CI 0.43-0.90 p=0.013), obesity (HR 0.31, 95% CI 0.18-0.54 p=0.000) and depression (HR 2.54, 95% CI 1.64-3.94 p=0.000).Conclusion:In this study of real clinical practice, secukinumab showed a 66% retention rate at one year in a population mostly refractory to biological therapy. The main cause of discontinuation was lack of efficacy. The AAs that led to drug discontinuation occurred mainly in the first 6 months of treatmentAcknowledgments:Raquel Linge, Agnes Díaz and Juan CalatayudDisclosure of Interests:Ignacio Villa-Blanco Consultant of: UCB, Speakers bureau: Novartis, MSD, Lilly, Sara Alonso Castro: None declared, Sabela Fernández: None declared, José Luis Martín-Varillas Grant/research support from: AbbVie, Pfizer, Janssen and Celgene, Speakers bureau: Pfizer and Lilly, Lilian Consuelo Charca Benavente: None declared, Marina Pino Martínez: None declared, Leyre Riancho-Zarrabeitia Grant/research support from: Yes, Speakers bureau: Yes, Isla Morante Bolado: None declared, Montserrat Santos Gómez: None declared, Anahy Brandy-Garcia: None declared, Elena Aurrecoechea: None declared, Loreto Carmona Grant/research support from: Novartis Farmaceutica, SA, Pfizer, S.L.U., Merck Sharp & Dohme España, S.A., Roche Farma, S.A, Sanofi Aventis, AbbVie Spain, S.L.U., and Laboratorios Gebro Pharma, SA (All trhough institution), Rubén Queiró Silva: None declared

Abstract
Background:Patients with spondyloarthritis (SpA) suffer not only from pain or physical disability, but they are also affected in multiple facets of life due to this condition (disease impact). Recently, the ASAS group has proposed a new way of capturing the impact that SpA have on patients’ lives, based on the principles proposed by the International classification of functioning, disability and health (ICF). The tool obtained (ASAS-health index or ASAS-HI) includes 17 items that cover most ICF domains.Objectives:To analyze the performance of ASAS-HI in real clinical practice, by comparing it with other standard measures of evaluation of SpA. To assess whether ASAS-HI is able to identify disease activity states in these patients.Methods:This cross-sectional study included 111 consecutive patients with SpA (ASAS criteria). The correlation (Spearman’s rho) between ASAS-HI, BASDAI, ASDAS, and BASFI was analyzed. ROC curves were constructed to analyze ASAS-HI values that determined BASDAI remission, ASDAS inactive disease, and ASDAS low activity. A logistic regression was made to determine the ASAS-HI items with greater capability to discriminate the state of remission / inactive disease.Results:Seventy-four men and 37 women were included, mean age of 43.3 ± 10.6 years. The average duration of illness was 7.6 ± 6.8 years. Sixty percent of the series was under biological therapy. HLA-B27 was positive in 79.3%. The average value of ASAS-HI was 5.4 ± 3.8. There were significant correlations between ASDAS and BASDAI (rho: 0.89, p <0.0005), BASDAI and BASFI (rho: 0.86, p <0.0005), BASFI and ASDAS (rho: 0.78, p <0.0005), BASDAI and ASAS-HI (rho: 0.77, p <0.0005), ASDAS and ASAS-HI (rho: 0.70, p <0.0005). The optimal cut-off point of ASAS-HI for BASDAI remission (Table 1) corresponded to a value ≤ 2. As for the value of ASAS-HI to define ASDAS inactive disease (Table 2), this was ≤ 0. For ASDAS low activity, the value was ≤ 6 [area under the ROC curve 0.82 (95% CI: 0.73-0.89), Sen: 89.5%, Spe: 66.1). In the multivariate regression, the two ASAS-HI items associated with BASDAI non-remission were, “I often get frustrated” [OR 9.2 (95% CI: 1.2-69.4), p = 0.032], and “I sleep badly at night” [OR 7.7 (95% CI: 1.4-41.6), p = 0.018). As for ASDAS, the only question of ASAS-HI significantly associated with active disease was “pain sometimes disrupts my normal activities” [OR 8.7 (95% CI: 1.7-45.2), p = 0.010].Conclusion:ASAS-HI correlates well with most outcome measures in SpA. A cut-off point of ASAS-HI ≤ 6 identifies a low disease activity and could be considered a good treatment objective. The evaluation of SpA should include not only conventional measures (BASDAI / ASDAS) but also disease impact measures (ASAS-HI).Table 1.Area under the ROC curve (AUC)0.88395% CI0.809-0.936p-value<0.0001Optimal cut-off point≤2Sensitivity65.71Specificity96.05Table 2.Area under the ROC curve (AUC)0.87395% CI0.797-0.929p-value<0.0001Optimal cut-off point≤0Sensitivity58.82Specificity94.68Disclosure of Interests:None declared

Abstract
Background:Interstitial Lung Disease (ILD) is a severe extraarticular manifestation of rheumatoid arthritis (RA). In this line, several radiological patterns of RA-ILD have been described: i) usual interstitial pneumonia (UIP), ii) nonspecific interstitial pneumonia (NSIP), iii) obliterating bronchiolitis, iv) organized pneumonia and mixed patterns. Abatacept (ABA) could be an effective and safe option for patients with RA-ILD, although the response in the different radiological patterns is not well defined.Objectives:Our aim was to assess the response to ABA in different radiological patterns of ILD.Methods:Observational retrospective multicenter study of RA-ILD treated with ABA. ILD was diagnosed by HRCT and classified by radiological patterns in 3 different subgroups of RA-ILD: a) UIP, b) NSIP and c) “other”. ABA was used sc. or iv. at standard dose. We assessed: a) Dyspnoea (MMRC scale; significant variation ≥1); b) Respiratory function tests (significant changes ≥10% in FVC and DLCO); c) HRCT imaging; d) DAS28 e)prednisone dose.Variables were collected at months 0, 3, 6, 12 months and subsequently every 12 months until a maximum of 60 months.Results:We included 263 patients: 106 UIP, 84 NSIP and 73 others (150 women / 113 men), mean age 64.64±10 years. Total patients positive for RF or CCPA were 235 (89.4%) and 233 (88.6%), respectively. In 26 out of 263 patients, the development of ILD was closely related to the administration of sDMARDs (MTX n = 11 and LFN n = 1) or bDMARDs (ETN n = 5, ADA n = 4, CZP n = 2 and IFX n = 3). Patient characteristics are shown in table 1. Figure 1 shows the evolution of the cases with available data after a mean follow-up of 22.7±19.7 months. Mean DLCO and FVC remained stable in the 3 groups without statistically significant changes, and all the groups showed a statistically significant reduction in DAS28 and prednisone dose.Conclusion:ABA could be a good choice of treatment in patients with RA-ILD independently of the radiological pattern of ILD.Disclosure of Interests:Carlos Fernández-Díaz Speakers bureau: Brystol Meyers Squibb, Santos Castañeda: None declared, Rafael Melero: None declared, J.

Abstract
Background:Interstitial Lung Disease (ILD) is a severe complication of Rheumatoid Arthritis (RA). Several conventional disease-modifying anti-rheumatic drugs (cDMARDs) and biologic (b) DMARDs may induce or impaired ILD-RA. Abatacept (ABA) may be useful in ILD-RA (1).Objectives:To assess the efficacy and safety of ABA in a large series of ILD-RA for a long-term follow-up.Methods:Multicenter open-level study of ILD-RA treated with at least 1 dose of ABA. ILD was diagnosed by high-resolution computed tomography (HRTC). We study these outcomes: a) 1-point change Modied Medical Research Council (MMRC); b) forced vital capacity (FVC) and/or DLCO improvement or decline ≥10%; c) change in HRCT, d) change in DAS28. e) Prednisone dose. Values were collected at 0, 3, 6, 12 and then every 12 months.Results:We studied 263 patients (150 women/113 men) (mean age;64.6±10 years), with ILD-RA. At ABA-onset they were smokers or exsmoker (53.8%), positive APCC (88.6%), median [IQR] duration of ILD of 12 [3-41.25] months, mean DLCO (65.7±18.3) and FVC (85.9±21.8).The ILD-pattern were usual interstitial pneumonia (UIP) (40.3%), non-specific interstitial pneumonia (NSIP) (31.9%) and others (27.8%).ABA was prescribed at standard subcutaneous (125 mg/w) in 196 (74.5%) or intravenously (10 mg/kg/4 w) in 67 (25.5%); in monotherapy (n=111) or combined with cDMARDs (n=152); especially leflunomide (n=55), MTX (n=46), or antimarials (n=21).After a mean follow-up of 22.7±19.7 months most outcomes remain stable (Figure). Moreover, DAS28 improved from 4.5±1.5 to 3.1±1.3; prednisone dose reduced from a median 7.5 [5-10] to 5 mg [5-7.5] and retention rate was 76.4%. The main adverse effects were serious infections (n=28), neoplasia (n=3), serious infusion reaction (n=1) and myocardial infarction (n=1).Conclusion:ABA seems effective and relatively safe in ILD-RA.References:[1]Fernández-Díaz C et al.

Hyaluronic acid capacitation induces intracellular signals modulated by membrane-associated adenylate cyclase and tyrosine kinase involved in bovine in vitro fertilization.

Abstract
Heparin is the most commonly used in vitro capacitation inducer in the bovine. However, hyaluronic acid (HA) has been recently used for capacitation induction as well as for other reproductive biotechnologies, such as sperm selection and in vitro fertilization (IVF). Our aim was to induce sperm capacitation with heparin or HA in order to study mAC and TK intracellular signals and their relation with cleavage and blastocyst rates after IVF as well as with the oxidative status of the potential bovine embryos. 2,5-dideoxyadenosine and genistein were used as mAC and TK inhibitors, respectively. Sperm capacitation was analyzed using CTC technique, sperm plasma membrane and acrosome integrity were determined using trypan blue stain and differential interference contrast, and mitochondrial activity was evaluated using fluorochrome JC-1. Cleavage rate was analyzed 48h and blastocyst production 7-8 days after IVF, while cytosolic oxidative activity was determined using RedoxSensor Red CC-1 fluorochrome 7h after IVF. When mAC and TK inhibitors were added to sperm samples, only capacitation decreased significantly both in HA and heparin treated samples (P < 0.05), but plasma membrane and acrosome integrity percentages were not affected in any of these groups (P > 0.05). Sperm mitochondrial membrane potential only decreased in heparin treated samples in the presence of both inhibitors (P < 0.05). Oocytes activated with HA sperm treated samples with the addition of 2,5-dideoxyadenosine and genistein presented a lower cytosolic oxidative status than those activated with sperm treated with HA alone (P < 0.05). On the other hand, oocytes activated with heparin treated sperm samples presented a lower cytosolic oxidative status only in the presence of 2,5-dideoxyadenosine (P < 0.05). Therefore, mAC and TK present a differential participation in heparin and HA sperm induced capacitation and mitochondrial function as well as in IVF.

Abstract
INTRODUCTION AND OBJECTIVE Eosinophilic esophagitis is a chronic, immune-mediated disease described in case series and publications worldwide. Over the past twenty years, the authors of different studies have attempted to evaluate its incidence and prevalence. The objetive of the present study was to estimate the prevalence of eosinophilic esophagitis in a group of children seen at 36 pediatric gastroenterology centers in ten Latin American countries. MATERIALS AND METHODS A multicenter, observational, and cross-sectional study was conducted that estimated the period prevalence of eosinophilic esophagitis in children seen at outpatient consultation and that underwent diagnostic upper gastrointestinal endoscopy for any indication at 36 centers in 10 Latin American countries, within a 3-month time frame. RESULTS Between April and June 2016, 108 cases of eosinophilic esophagitis were evaluated. Likewise, an average of 29,253 outpatient consultations and 4,152 diagnostic upper gastrointestinal endoscopies were carried out at the 36 participating centers. The period prevalence of eosinophilic esophagitis in the population studied (n=29,253) was 3.69 cases×1,000 (95% CI: 3.04 to 4.44), and among the children that underwent routine upper gastrointestinal endoscopy (n=4,152), it was 26x1,000 (95% CI: 22.6 to 29.4). CONCLUSIONS The general period prevalence of eosinophilic esophagitis in a group of children evaluated at 36 Latin American pediatric gastroenterology centers was 3.69×1,000, and in the children that underwent endoscopy, it was 26×1,000. There was important prevalence variability between the participating countries and centers. The present analysis is the first study conducted on the prevalence of pediatric eosinophilic esophagitis in Latin America.

Abstract
OBJECTIVE To compare the measurement of antimicrobial consumption by defined daily dose (DDD) versus by days of therapy (DOT). DESIGN Retrospective analysis of clinical and administrative data from patients admitted to a polyvalent ICU. SETTING ICU at a University Hospital in Spain. PATIENTS All patients admitted to the ICU. INTERVENTIONS None. MAIN VARIABLES OF INTEREST For the DDD method, the World Health Organization (WHO)-assigned DDD was determined for the all the prescribed antimicrobials. For the DOT method, one DOT represented the administration of a single agent on a given day regardless of the number of doses administered. To express aggregate use, total DDDs and total DOTs were normalized to 100 patient-days. RESULTS During the study period, 2393 adult patients were admitted to the ICU. Total median antimicrobial drugs measured by DDDs was 535.3 (IQR 319.8-845.5) vs. 344.0 (IQR 117.2-544.5) when measured by DOTs, p<0.001. When antimicrobial consumption was normalized to 100 patient-days, median antimicrobial consumption was also higher when measured by DDDs [2.98/100 patient-days (IQR 1.76-5.25) vs. 1.89/100 patient-days (IQR 0.64-3.0) when measured by DOTs, p<0.001]. CONCLUSIONS For most antibacterial and antifungal drugs used in critically ill patients, estimates of aggregate antibiotic use by DDDs per 100 patient-days and DOTs per 100 patient-days are discordant because the administered dose is dissimilar from the WHO-assigned DDD. DOT methods should be recommended to avoid the overestimation that occurs with DDDs in adult critically ill patients.

Abstract
Social hierarchies are crucial for a group's survival and can influence the way an individual behaves and relates to a given social context. The study of social rank has been classically based on ethological and observational paradigms, but it recently has taken advantage of the use of other approaches, such as the tube test that measures territorial dominance without the display of in situ aggression and is executable in group-living animals. However, little is known about how previous basal individual differences affect the development of dominance hierarchy measured in the tube test. We have analyzed in male mice body weight, locomotion, anxiety, and serum corticosterone both before and after the tube test, as well as adult hippocampal neurogenesis and transcriptome in the prefrontal cortex after the hierarchy had been established. We found differential gene expression between dominants and subordinates but no association between the other parameters and social status, neither pre- nor posttest. Our findings reveal that social rank in mice is stable along time and is not related to basal differences in stress, mood, or physical features. Lastly, real-time quantitative PCR analysis confirmed differential expression of vomeronasal and olfactory receptors in the cerebral cortex between dominant and subordinate individuals, suggesting that differential brain gene expression in the medial prefrontal cortex could potentially be used as a biomarker of social dominance.-Pallé, A., Zorzo, C., Luskey, V. E., McGreevy, K. R., Fernández, S., Trejo, J. L. Social dominance differentially alters gene expression in the medial prefrontal cortex without affecting adult hippocampal neurogenesis or stress and anxiety-like behavior.

Abstract
INTRODUCTION A surgical intervention is a stress situation for every human being. Parents of children who undergo scheduled surgeries have some degree of anxiety about them. OBJECTIVE To identify the main paternal concerns regarding surgery. Assess the influence of working in health (nurses, auxiliary staff and doctors) to underestimate, magnify or mislead the real concerns. MATERIAL AND METHOD A comparative cross-sectional study was conducted between two populations divided by their relationship with the hospital setting that completed a questionnaire with 35 items. 138 questionnaires were collected and analyzed. RESULTS Differences are observed regarding the perception we have, as hospital staff, of the levels, relationships and types of concerns that we believe parents present before their child's surgery regarding the true perceptions that these parents present. CONCLUSION The present study shows that, although the hospital staff has experience in the management of pediatric patients and their family environment, the habituation to the hospital environment can generate small distortions in terms of the levels and groupings of the different concerns present before the hospital surgery of a child, having to take it into account to offer the best care work.

Abstract
The use of native microorganisms with probiotic capacity is an alternative tool for the treatment and prevention of several diseases that affect animals, such as neonatal calf diarrhoea. The selection of probiotic strains within a collection is based on different in vitro and in vivo assays, which predict their potential. The aim of this study was to characterise a group of native Lactobacillus spp. strains isolated from faeces of healthy calves using an in vitro approach and to assess their ability to colonise the gastrointestinal tract (GIT) of calves. Native Lactobacillus spp. strains were evaluated on their capacity to survive low pH conditions and bile salts presence, biofilm formation and adhesion to both mucus and Caco-2 cells. Based on the in vitro characterisation, four strains (Lactobacillus johnsonii TP1.1, Lactobacillus reuteri TP1.3B, L. johnsonii TP1.6 and Lactobacillus amylovorus TP8.7) were selected to evaluate their capacity to colonise and persist in the GIT of calves. The assessment of enteric persistence involved an in vivo assay with oral administration of probiotics and quantification in faeces of the administered bacterial species with real-time quantitative PCR (qPCR). The study was conducted using 15 calves (1-month-old) which were divided into five groups of three animals, four of which were treated with four different selected strains and one was the control group. Strains TP1.3B and TP1.6 managed to persist in treated animals until ten days after the end of the administration period, indicating that they could be promising candidates for the design of probiotics for calves.

Abstract
BACKGROUND Clinical complications associated with atherosclerotic plaques arise from luminal obstruction due to plaque growth or destabilization leading to rupture. We previously demonstrated that overexpression of insulin receptor isoform A (IRA) and insulin-like growth factor-I receptor (IGF-IR) confers a proliferative and migratory advantage to vascular smooth muscle cells (VSMCs) promoting plaque growth in early stages of atherosclerosis. However, the role of insulin receptor (IR) isoforms, IGF-IR or insulin-like growth factor-II receptor (IGF-IIR) in VSMCs apoptosis during advanced atherosclerosis remains unclear. METHODS We evaluated IR isoforms expression in human carotid atherosclerotic plaques by consecutive immunoprecipitations of insulin receptor isoform B (IRB) and IRA. Western blot analysis was performed to measure IGF-IR, IGF-IIR, and α-smooth muscle actin (α-SMA) expression in human plaques. The expression of those proteins, as well as the presence of apoptotic cells, was analyzed by immunohistochemistry in experimental atherosclerosis using BATIRKO; ApoE-/- mice, a model showing more aggravated vascular damage than ApoE-/- mice. Finally, apoptosis of VSMCs bearing IR (IRLoxP+/+ VSMCs), or not (IR-/- VSMCs), expressing IRA (IRA VSMCs) or expressing IRB (IRB VSMCs), was assessed by Western blot against cleaved caspase 3. RESULTS We observed a significant decrease of IRA/IRB ratio in human complicated plaques as compared to non-complicated regions. Moreover, complicated plaques showed a reduced IGF-IR expression, an increased IGF-IIR expression, and lower levels of α-SMA indicating a loss of VSMCs. In experimental atherosclerosis, we found a significant decrease of IRA with an increased IRB expression in aorta from 24-week-old BATIRKO; ApoE-/- mice. Furthermore, atherosclerotic plaques from BATIRKO; ApoE-/- mice had less VSMCs content and higher number of apoptotic cells. In vitro experiments showed that IGF-IR inhibition by picropodophyllin induced apoptosis in VSMCs. Apoptosis induced by thapsigargin was lower in IR-/- VSMCs expressing higher IGF-IR levels as compared to IRLoxP+/+ VSMCs. Finally, IRB VSMCs are more prone to thapsigargin-induced apoptosis than IRA or IRLoxP+/+ VSMCs. CONCLUSIONS In advanced human atherosclerosis, a reduction of IRA/IRB ratio, decreased IGF-IR expression, or increased IGF-IIR may contribute to VSMCs apoptosis, promoting plaque instability and increasing the risk of plaque rupture and its clinical consequences.

Abstract
The most frequent presentation of esophageal cancer is adenocarcinoma and squamous cell carcinoma. In recent years, the latter has decreased its incidence increasing the adenocarcinoma. Currently, another type of tumor with a much lower incidence has been described, which has a neuroendocrine component along with another exocrine glandular component and has been classified since 2010 as mixed adenoneuroendocrine carcinoma (MANEC). We present the case of a 68-year-old male with a history of dyspepsia and epigastric pain who after performing a gastroscopy, was diagnosed with a malignant neoplasm of the esophagus. The patient underwent a total esophagectomy with reconstruction by tubular gastroplasty with cervical anastomosis. The final result of the piece after immunohistochemistry revealed that the tumor was composed of one component of adenocarcinoma in 60% together with another component compatible with neuroendocrine in 40%. With these findings and according to the World Health Organization classification of 2010 was diagnosed as esophageal MANEC. MANECs are rare tumors, described in other locations of the digestive tract, the esophagus being an infrequent location. Its preoperative diagnosis is difficult, and it is not until the final analysis of the complete piece by means of specific immunohistochemical techniques when its diagnosis can be established. Its treatment is fundamentally surgical, whereas the adjuvant therapeutic schemes with chemotherapy are not well defined at present because of their low incidence.

Abstract
It is unknown how the lack of insulin receptor (IR)/insulinlike growth factor I receptor (IGFIR) in a tissue-specific manner affects brown fat development and mitochondrial integrity and function, as well as its effect on the redistribution of the adipose organ and the metabolic status. To address this important issue, we developed IR/IGFIR double-knockout (DKO) in a brown adipose tissue-specific manner. Lack of those receptors caused severe brown fat atrophy, enhanced beige cell clusters in inguinal fat; loss of mitochondrial mass; mitochondrial damage related to cristae disruption; and the loss of proteins involved in autophagosome formation, mitophagy, mitochondrial quality control, and dynamics and thermogenesis. More important, DKO mice showed an impaired thermogenesis upon cold exposure, based on a failure in the mitochondrial fission mechanisms and a much lower uncoupling protein 1 transcription rate and content. As a result, DKO mice under normal conditions showed an obesity susceptibility, revealed by increased body fat mass and insulin resistance. Upon consumption of a high-fat diet, DKO mice displayed frank obesity, as shown by increased body weight, increased adiposity, insulin resistance, hyperinsulinemia, and hypertriglyceridemia, all consistent with a metabolic syndrome. Collectively, our data suggest a cause-and-effect relationship between failure in brown fat thermogenesis and increased adiposity and obesity.

Abstract
A reactor cell for in situ studies of individual catalyst nanoparticles or surfaces by nano-focused (coherent) x-ray diffraction has been developed. Catalytic reactions can be studied in flow mode in a pressure range of 10-2-103 mbar and temperatures up to 900 °C. This instrument bridges the pressure and materials gap at the same time within one experimental setup. It allows us to probe in situ the structure (e.g., shape, size, strain, faceting, composition, and defects) of individual nanoparticles using a nano-focused x-ray beam. Here, the setup was used to observe strain and facet evolution of individual model Pt catalysts during in situ experiments. It can be used for heating other (non-catalytically active) nanoparticles (e.g., nanowires) in inert or reactive gas atmospheres or vacuum as well.

Abstract
BACKGROUND There has been an increase in the prevalence of hypersensitivity to Anisakis simplex. There are fish parasites other than Anisakis simplex whose allergenicity has not yet been studied. OBJECTIVE To assess IgE hypersensitivity caused by fish parasite allergens in patients with gastro-allergic symptoms after consumption of fish, shellfish or cephalopods, compared with healthy subjects, pollen allergic individuals and children with digestive symptoms after eating marine food. METHODS We carried out in vivo tests (skin prick) and in vitro tests (specific IgE determination, Western blot) and component resolved diagnostics (CRD) using microarray analysis in all patients. RESULTS CRD better detected sensitisation to allergens from marine parasites than skin prick tests and determination of specific IgE by CAP. Sensitisation to Gymnorhynchus gigas was detected in 26% of patients measured by skin prick tests and 36% measured by IgE. CONCLUSIONS The prevalence of hypersensitivity to marine parasite allergens other than Anisakis simplex should be studied, and the most appropriate technique for this is CRD.
