Abstract
The pursuit of efficient, profitable, and ecofriendly materials has defined solar cell research from its inception to today. Some materials, such as copper nitride (Cu3N), show great promise for promoting sustainable solar technologies. This study employed reactive radio-frequency magnetron sputtering using a pure nitrogen environment to fabricate quality Cu3N thin films to evaluate how both temperature and gas working pressure affect their solar absorption capabilities. Several characterization techniques, including X-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS), Raman spectroscopy, scanning electron microscopy (SEM), nanoindentation, and photothermal deflection spectroscopy (PDS), were used to determine the main properties of the thin films. The results indicated that, at room temperature, it is possible to obtain a material that is close to stoichiometric Cu3N material (Cu/N ratio ≈ 3) with (100) preferred orientation, which was lost as the substrate temperature increases, demonstrating a clear influence of this parameter on the film structure attributed to nitrogen re-emission at higher temperatures. Raman microscopy confirmed the formation of Cu-N bonds within the 628-637 cm-1 range. In addition, the temperature and the working pressure significantly also influence the film hardness and the grain size, affecting the elastic modulus. Finally, the optical properties revealed suitable properties at lower temperatures, including bandgap values, refractive index, and Urbach energy. These findings underscore the potential of Cu3N thin films in solar energy due to their advantageous properties and resilience against defects. This research paves the way for future advancements in efficient and sustainable solar technologies.

Abstract
This material can be considered to be an interesting eco-friendly choice to be used in the photovoltaic field. In this work, we present the fabrication of Cu3N thin films by reactive radio-frequency (RF) magnetron sputtering at room temperature, using nitrogen as the process gas. Different RF power values ranged from 25 to 200 W and gas pressures of 3.5 and 5 Pa were tested to determine their impact on the film properties. The morphology and structure were exhaustively examined by Atomic Force Microscopy (AFM), Fourier Transform Infrared (FTIR) and Raman Spectroscopies and X-ray Diffraction (XRD), respectively. The AFM micrographs revealed different morphologies depending on the total pressure used, and rougher surfaces when the films were deposited at the lowest pressure; whereas FTIR and Raman spectra exhibited the characteristics bands related to the Cu-N bonds of Cu3N. Such bands became narrower as the RF power increased. XRD patterns showed the (100) plane as the preferred orientation, that changed to (111) with the RF power, revealing a worsening in structural quality. Finally, the band gap energy was estimated from transmission spectra carried out with a Perkin Elmer 1050 spectrophotometer to evaluate the suitability of Cu3N as a light absorber. The values obtained demonstrated the capability of Cu3N for solar energy conversion applications, indicating a better film performance under the sputtering conditions 5.0 Pa and RF power values ranged from 50 to 100 W.

Abstract
Objective To evaluate the rate of thrombosis, bleeding and mortality comparing anticoagulant doses in critically ill COVID-19 patients. Design Retrospective observational and analytical cohort study. Setting COVID-19 patients admitted to the intensive care unit of a tertiary hospital between March and April 2020. Patients 201 critically ill COVID-19 patients were included. Patients were categorized into three groups according to the highest anticoagulant dose received during hospitalization: prophylactic, intermediate and therapeutic. Interventions The incidence of venous thromboembolism (VTE), bleeding and mortality was compared between groups. We performed two logistic multivariable regressions to test the association between VTE and bleeding and the anticoagulant regimen. Main variables of interest VTE, bleeding and mortality. Results 78 patients received prophylactic, 94 intermediate and 29 therapeutic doses. No differences in VTE and mortality were found, while bleeding events were more frequent in the therapeutic (31%) and intermediate (15%) dose group than in the prophylactic group (5%) (p < 0.001 and p < 0.05 respectively). The anticoagulant dose was the strongest determinant for bleeding (odds ratio 2.4, 95% confidence interval 1.26-4.58, p = 0.008) but had no impact on VTE. Conclusions Intermediate and therapeutic doses appear to have a higher risk of bleeding without a decrease of VTE events and mortality in critically ill COVID-19 patients.

Abstract
Copper nitride, a metastable semiconductor material with high stability at room temperature, is attracting considerable attention as a potential next-generation earth-abundant thin-film solar absorber. Moreover, its non-toxicity makes it an interesting eco-friendly material. In this work, copper nitride films were fabricated using reactive radio frequency (RF) magnetron sputtering at room temperature, 50 W of RF power, and partial nitrogen pressures of 0.8 and 1.0 on glass and silicon substrates. The role of argon in both the microstructure and the optoelectronic properties of the films was investigated with the aim of achieving a low-cost absorber material with suitable properties to replace the conventional silicon in solar cells. The results showed a change in the preferential orientation from (100) to (111) planes when argon was introduced in the sputtering process. Additionally, no structural changes were observed in the films deposited in a pure nitrogen environment. Fourier transform infrared (FTIR) spectroscopy measurements confirmed the presence of Cu-N bonds, regardless of the gas environment used, and XPS indicated that the material was mainly N-rich. Finally, optical properties such as band gap energy and refractive index were assessed to establish the capability of this material as a solar absorber. The direct and indirect band gap energies were evaluated and found to be in the range of 1.70-1.90 eV and 1.05-1.65 eV, respectively, highlighting a slight blue shift when the films were deposited in the mixed gaseous environment as the total pressure increased.

Abstract
INTRODUCTION Disulfiram-induced-encephalopathy is a rare complication that has been well described in adults. Although it usually occurs in acute intoxication with high doses of disulfiram, late onset encephalopathy has also been reported. Some authors propose the inhibition of dopamine beta-hydroxylase mediated by toxic metabolites of disulfiram as the main responsible, but the exact mechanism remains unclear. The aim of this report was to describe the clinical and neuroimaging findings in an unusual case of acute encephalitis due to disulfiram toxicity associated to chronic intranasal consume. CASE REPORT A chronic alcoholic who referred snorted use of a very high dose of disulfiram without simultaneous alcohol intake developed an acute encephalopathy with a rapidly progressive respiratory failure. A characteristic neuroimage finding consisting in extensive bilateral symmetric involvement of both pallidal nuclei was described. Recovery and neurologic improvement were slow. Two months after the intoxication, the patient still had slight intentional tremor and a scheduled magnetic resonance imaging. showed evolution of symmetrical areas of cytotoxic edema to necrosis. CONCLUSION Disulfiram-induced neurotoxicity must be suspect during chronic therapy with disulfiram or after acute ingestion of high doses. Symptoms such as symmetric sensory and motor neuropathy, confusion, catatonia, parkinsonism, ataxia, choreoathetosis, seizures and encephalopathy should make us rule out this disorder. A brain imaging test should be performed in these patients since a characteristic involvement of both nuclei pallidus has been described, but it is not present in all patients.

Abstract
BackgroundOcular and Neurobehçet’s Disease (NBD) are the most severe manifestations of Behcet’s disease (1-4). NBD can be classified as a) primary neural parenchymal lesions, also known as parenchymal NBD (p-NBD) or b) secondary to vascular involvement or non-parenchymal NBD (np-NBD) (4). Response to biologic therapy (BT) in these two refractory subtypes of NBD is unknown.ObjectivesTo assess efficacy and safety of BT in refractory subtypes of NBD.MethodsOpen-label multicenter study of refractory NBD from 21 different referral National Hospitals. NBD diagnosis was based on the International Consensus Recommendation criteria (4). Efficacy was determined by complete or partial response and no-response. Complete, partial or no response was defined according to the resolution of the neurological syndrome (signs and/or symptoms) after the BT onset.ResultsWe studied 41 patients (21 women/20 men; mean age: 40.6±10.8 years). NBD was classified as p-NBD (n= 33, 80.5%) and np-NBD (n=17, 41.5%). There were no significant differences in baseline general features and in neurological clinical response in both subgroups (Table 1 and Figure 1). The first BT used in p-NBD were Infliximab (IFX) (n=15), Adalimumab (ADA) (n=11), Golimumab (GLM) (n=3), Tocilizumab (TCZ) (n=2) and Etanercept (ETN) (n=2) and in np-NBD were IFX (n=9), ADA (n=6), TCZ (n=1) and ETN (n=1).Table 1.Main features of p-NBD and np-NBDTotalp-NBDnp-NBDP p-NBD vs np-NBDAge at biological therapy initiation, years (mean±SD)44±13.941.4±9.639.4±10.60.412Gender, n (m/f) (%)21/20 (48.8/52.2)18/15 (54.5/45.5)5/12 (29.4/70.6)0.091HLAB51 +/ patients tested, n (%)15/31 (57.7)14/25 (58.3)4/10 (40)0.391Oral aphthae, n (%)40 (97.6)32 (97)15 (88.2)0.323Cutaneous involvement, n (%)28 (63.4)23 (69.7)10 (58.8)0.603Ocular involvement, n (%)21 (48.8)15 (45.5)9 (52.9)0.616Vascular involvement, n (%)9 (22)10 (30.3)7 (41.2)0.442Articular involvement, n (%)9 (22)7 (21.2)3 (17.6)0.765Previous conventional Immunosuppressive drugs to BTAzathioprine24 (58.5)20 (60.6)10 (58.8)-Methotrexate16 (39.0)12 (36.4)3 (17.6)-Cyclophosphamide13 (31.7)13 (39.4)5 (29.4)-Cyclosporine A9 (22.0)8 (24.2)3 (17.6)-Mycophenolate Mofetil2 (4.9)2 (6.1)0-Figure 1.Response to biological therapy according to NBD subtypes.After an overall mean follow-up of 57.5±50.9 months BT was switched in 22 patients due to inefficacy (n=16) or Adverse Effects (AE) (n=6) and in 4 cases was definitively discontinued because of complete prolonged remission (n=3) or AE (n=1). AE were observed in 7 (17.1%) patients. Severe AE were observed in 2 cases, one due to demyelinating disease and the other due to pulmonary tuberculosis, both in patients undergoing IFX therapy.

Abstract
BACKGROUND AND PURPOSE Uveal melanoma is the most common primary malignant intraocular tumour in the adult population, with a survival rate of 50% despite advances in treatment and knowledge of this disease. The presence of extraocular extension (EE) worsens the prognosis of these patients, so its proper identification can ensure its management and early intervention. Ophthalmological ultrasound is the technique of choice for the diagnosis and follow-up of these patients, both of the anterior EE using ultrasonic biomicroscopy (UBM), and the posterior EE using A and B ultrasound. The aim of this study is to describe the ultrasound characteristics of the BMU and the A and B ultrasound. MATERIAL AND METHODS A descriptive and retrospective study is carried out on patients diagnosed with uveal melanoma (UM) and EE from 2003 to 2019. The ultrasound characteristics of the local disease and the follow-up after treatment were recorded completely and at each visit. In the case of anterior EE, photographs of the anterior segment and UBM were taken, while those involving the posterior segment were explored under A and B mode ultrasound. All enucleated eyes were sent for anatomopathological study. RESULTS Ten patients with an average age of 72.3 years were included. The largest proportion of them were medium-sized tumours, followed by large and small ones. The most frequent morphology of the primary tumour was cupuliform. All the EE presented lower internal reflectivity compared to the primary tumour. No trans-scleral connection bridges were found between the primary tumour and the EE in the ultrasound studies. 50% of patients underwent primary enucleation at the time of diagnosis of intraocular MU due to the presence of the EE, and the remaining 50% presented the EE after initial treatment of the primary tumour with I125 brachytherapy. Sixty percent of the patients presented with posterior EE, and were therefore diagnosed with ultrasound A and B. The most frequent histopathological pattern with 87.5% of patients was the epithelioid pattern. DISCUSSION Ultrasound scanning in patients with MU is mandatory for diagnosis and follow-up of EE. BMU and A and B ultrasound are the test of choice for anterior and posterior EE, respectively. EE have particular ultrasound characteristics such as low internal reflectivity, regularity of their contour and their location usually adjacent to the base of the primary intraocular tumor.

Abstract
Background:Neuro-Behçet’s disease (NBD) is a severe complication of Behcet’s disease (BD). Despite well-established therapies with glucocorticoids and conventional immunosuppressants (cIS), a significant proportion of patients are refractory.Objectives:To assess efficacy and safety of biologic therapy (BT) in NBD refractory to glucocorticoids and at least one cIS.Methods:Open-label multicenter study of refractory NBD from 23 different referral Spanish Hospitals. Main outcome was neurological response. Secondarily, analytical efficacy was measured by Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP) and Hemoglobin (Hb) at baseline, 6 months, 1 year and 2 years.Results:We studied 42 patients (21 women/ 21 men; mean age 40.4±10.8 years). HLA B51 was positive in 15 out of 37 (40.5%) patients tested. Non-neurological manifestations were oral ulcers (n=41, 97.6%), genital ulcers (n=31, 73.8%), skin lesions (n=28, 66.7%), arthralgia (n=27, 64.3%), uveitis (n=21, 50.0%), arthritis (n=9, 21.4%), venous thrombosis (n=9, 21.4%) and arterial thrombosis (n=4, 9.5%). The underlying neurologic manifestation were parenchymal (n=34, 81.0 %) and non-parenchymal (n=17, 40.5%) involvement (Table 1). The first BT used was infliximab (n=20), adalimumab (n=13), golimumab (n=3), tocilizumab (n=3) and etanercept (n=2).After 58.2±51.4 months since initiation of BT, neurological response was complete (n=27; 64.3%), or partial (n=11, 26.1%) (Figure 1). Only 4 (9.5%) patients did not respond. After 6 months of BT, ESR improved from.31.5±25.6 to 15.3±11.9 mm/h (p=0.005), CRP from 1.4 [0.2-12.8] to 0.3[0.1-3] mg/dL (p= 0.002) and Hb from 13.1±1.6 to 13.8±1.3 g/dL (p=0.005).Figure 1.Neurological clinical response to biological therapy.Primary failure was observed in 16 (38.1%) patients due to inefficacy (n=11, 68.8%) or adverse effects (n=5, 31.3%). Similarly, causes of secondary failure (n=6, 14.3%) were inefficacy (n=5, 83.3%) and adverse effects (n=1, 16.7%). No serious adverse effects were observed.Conclusion:BT, especially monoclonal anti-TNF drugs, seems to be effective and safe in refractory NBD.Table 1.Neurologic manifestation of 42 patients with refractory neurobehçet's disease treated with biologic therapy.Parenchymal subtype, n (%)34 (81.0)-Hemiparesis8 (19.1)-Polineuropathy8 (19.1)-Encephalopathy6 (14.3)-Cognitive impairments4 (9.5)-Optic neuropathy4 (9.5)-Ophtalmoparesis4 (9.5)-Other cranial nerve involvement3 (7.1)-Hemihypoesthesia3 (7.1)-Cerebellar dysphasia1 (2.4)-Cerebellar involvement1 (2.4)-Non-steroidal psicosis1 (2.4)Non-parenchymal subtype, n (%)17 (40.5)-Aseptic meningitis12(28.6)-Thrombosis4 (9.5)-Intracranial hypertension1 (2.4)Disclosure of Interests:Alba Herrero-Morant: None declared, José Luis Martín-Varillas Grant/research support from: AbbVie, Pfizer, Lilly, Janssen, and Celgene, Santos Castañeda: None declared, Iñigo González-Mazón: None declared, Olga Maiz: None declared, Ana Blanco Speakers bureau: AbbVie, Julio Sánchez: None declared, Norberto Ortego: None declared, Enrique Raya Speakers bureau: MSD, Grant/research support from: AbbVie, Alejandro Olive: None declared, Anahy Brandy-Garcia: None declared, Águeda Prior-Español: None declared, Clara Moriano: None declared, Elvira Diez Alvarez: None declared, Rafael Melero: None declared, Jenaro Graña: None declared, Álvaro Seijas-López: None declared, ANA URRUTICOECHEA-ARANA: None declared, Angel Ramos Calvo: None declared, Concepción Delgado Beltrán: None declared, Marta Loredo Martínez: None declared, Eva Salgado-Pérez: None declared, Francisca Sivera: None declared, Ignacio Torre-Salaberri: None declared, J.

Abstract
Background:Although the evidence that testifies to a higher prevalence of cardiometabolic risk factors in psoriatic disease is robust, there are not too many studies that have analyzed which disease traits are associated with these risk factors both in psoriasis and psoriatic arthritis1.Objectives:We aimed to analyze the frequency and disease-associated features of hyperlipidemia in psoriatic disease.Methods:Cross-sectional observational study that included 290 patients with psoriatic arthritis (mean age 54 ± 12 years, 54.8 % male, psoriasis average duration 21 ± 10 years) and 310 with psoriasis alone (mean age 53 ± 11.5 years, 52.9% male, psoriasis average duration 22 ± 11 years). We first analyzed the frequency of this comorbidity and then the factors associated with it using conditional logistic regression. The significant factors in this first model were introduced in a multivariate model using a backward stepwise approach.Results:Main disease features are depicted in Table 1. A total of 124 patients had hyperlipidemia (20.7%). Among arthritis patients, 82/290 (28.3%) had hyperlipidemia, compared with 42/310 (13.5%) of those with psoriasis alone (OR 2.5, 95%CI: 1.7–3.3, p < 0.001). Hyperlipidemia was independently associated with age [OR 1.07, 95%CI: 1.04–1.11, p < 0.001] and systemic therapy [OR 0.4, 95%CI: 0.17–0.89, p = 0.026].Conclusion:Hyperlipidemia is common in psoriatic disease, but much more among arthritis patients. This comorbid factor seems to go in parallel with increasing age. There is an inverse association between systemic treatment and hyperlipidemia that should be endorsed with well-designed longitudinal studies.References:[1]Puig L.

Abstract
Objectives In some patients the immune response triggered by SARS-CoV-2 is unbalanced, presenting an acute respiratory distress syndrome which in many cases requires intensive care unit (ICU) admission. The limitation of ICU beds has been one of the major burdens in the management around the world; therefore, clinical strategies to avoid ICU admission are needed. We aimed to describe the influence of tocilizumab on the need of transfer to ICU or death in non-critically ill patients. Material and methods A retrospective study of 171 patients with SARS-CoV-2 infection that did not qualify as requiring transfer to ICU during the first 24h after admission to a conventional ward, were included. The criteria to receive tocilizumab was radiological impairment, oxygen demand or an increasing of inflammatory parameters, however, the ultimate decision was left to the attending physician judgement. The primary outcome was the need of ICU admission or death whichever came first. Results A total of 77 patients received tocilizumab and 94 did not. The tocilizumab group had less ICU admissions (10.3% vs. 27.6%, P=0.005) and need of invasive ventilation (0 vs 13.8%, P=0.001). In the multivariable analysis, tocilizumab remained as a protective variable (OR: 0.03, CI 95%: 0.007-0.1, P=0.0001) of ICU admission or death. Conclusions Tocilizumab in early stages of the inflammatory flare could reduce an important number of ICU admissions and mechanical ventilation. The mortality rate of 10.3% among patients receiving tocilizumab appears to be lower than other reports. This is a non-randomized study and the results should be interpreted with caution.

Abstract
Neonatal calf diarrhoea is one of the challenges faced by intensive farming, and probiotics are considered a promising approach to improve calves' health. The objective of this study was to evaluate the effect of potential probiotic lactobacilli on new-born dairy calves' growth, diarrhoea incidence, faecal score, cytokine expression in blood cells, immunoglobulin A (IgA) levels in plasma and faeces, and pathogen abundance in faeces. Two in vivo assays were conducted at the same farm in two annual calving seasons. Treated calves received one daily dose of the selected lactobacilli (Lactobacillus reuteri TP1.3B or Lactobacillus johnsonii TP1.6) for 10 consecutive days. A faecal score was recorded daily, average daily gain (ADG) was calculated, and blood and faeces samples were collected. Pathogen abundance was analysed by absolute qPCR in faeces using primers directed at Salmonella enterica, rotavirus, coronavirus, Cryptosporidium parvum and three Escherichia coli virulence genes (eae, clpG and Stx1). The faecal score was positively affected by the administration of both lactobacilli strains, and diarrhoea incidence was significantly lower in treated calves. No differences were found regarding ADG, cytokine expression, IgA levels and pathogen abundance. Our findings showed that oral administration of these strains could improve gastrointestinal health, but results could vary depending on the calving season, which may be related to pathogen seasonality and other environmental effects.

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.

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
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
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
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.

Abstract
OBJECTIVE To explore the long-term effectiveness of rufinamide in managing Lennox-Gastaut Syndrome (LGS), other epileptic encephalopathies, and intractable focal epilepsies in adults and children in routine clinical practice. METHODS A multicentre, retrospective chart review of patients prescribed adjunctive rufinamide at seven Spanish epilepsy centres, with assessments at six and 12 months. RESULTS We evaluated data from 58 patients (40 male, age range 7-57 years), 25 of whom were diagnosed with LGS, 12 with other epileptic encephalopathies and 21 of whom were diagnosed with focal epilepsies, mainly frontal lobe. The mean daily rufinamide dose was 32.0 mg/kg (range 12.5-66.7 mg/kg) in children and 24.7 mg/kg (range 5.0-47.0 mg/kg) in adults, and the most commonly used concomitant antiepileptic drugs were levetiracetam and valproate. Rufinamide was discontinued in 25 patients (43.1%) during the 1-year follow-up, and the most common reason was lack of effectiveness (n = 12, 20.7% of total). The frequency of generalized tonic-clonic seizures was significantly reduced from baseline at 6 and 12 months (P = 0.001), both in patients with generalized epilepsies and in patients with focal epilepsies. Significant seizure frequency reduction from baseline was observed at 12 months (P = 0.01) for tonic/atonic seizures and at 6 months (P = 0.001) for focal seizures. Side effects were reported in 21 patients (36.2%): nausea, vomiting and weight loss were most frequent. CONCLUSIONS Rufinamide was well tolerated and was effective in reducing frequency of generalized tonic-clonic, tonic/atonic and focal seizures in both children and adults with severe refractory epilepsies, primarily LGS.

Expression of insulin receptor (IR) A and B isoforms, IGF-IR, and IR/IGF-IR hybrid receptors in vascular smooth muscle cells and their role in cell migration in atherosclerosis.

Abstract
Background Abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) is a major contributor to the development of atherosclerotic process. In a previous work, we demonstrated that the insulin receptor isoform A (IRA) and its association with the insulin-like growth factor-I receptor (IGF-IR) confer a proliferative advantage to VSMCs. However, the role of IR and IGF-IR in VSMC migration remains poorly understood. Methods Wound healing assays were performed in VSMCs bearing IR (IRLoxP+/+ VSMCs), or not (IR−/− VSMCs), expressing IRA (IRA VSMCs) or expressing IRB (IRB VSMCs). To study the role of IR isoforms and IGF-IR in experimental atherosclerosis, we used ApoE−/− mice at 8, 12, 18 and 24 weeks of age. Finally, we analyzed the mRNA expression of total IR, IRB isoform, IGF-IR and IGFs by qRT-PCR in the medial layer of human aortas. Results IGF-I strongly induced migration of the four cell lines through IGF-IR. In contrast, insulin and IGF-II only caused a significant increase of IRA VSMC migration which might be favored by the formation of IRA/IGF-IR receptors. Additionally, a specific IGF-IR inhibitor, picropodophyllin, completely abolished insulin- and IGF-II-induced migration in IRB, but not in IRA VSMCs. A significant increase of IRA and IGF-IR, and VSMC migration were observed in fibrous plaques from 24-week-old ApoE−/− mice. Finally, we observed a marked increase of IGF-IR, IGF-I and IGF-II in media from fatty streaks as compared with both healthy aortas and fibrolipidic lesions, favoring the ability of medial VSMCs to migrate into the intima. Conclusions Our data suggest that overexpression of IGF-IR or IRA isoform, as homodimers or as part of IRA/IGF-IR hybrid receptors, confers a stronger migratory capability to VSMCs as might occur in early stages of atherosclerotic process.

Abstract
BACKGROUND We describe the characteristics of an HIV-1 strain with six viral reverse transcriptase mutations (D67N, T69N/D, V118I, V179D, T215S and K219Q), which we have called the Malaga strain. This strain was detected in treatment-naive patients from southern Spain. METHODS The study was undertaken at the Virgen de la Victoria Hospital, Malaga, a reference centre for the study of HIV-1 genotype resistance in Andalusia (the 'Costa del Sol'), Spain. Genotypic resistance testing was done in an automated sequencer. Phylogenetic analysis was performed using a 630 bp region of the reverse transcriptase with the mutations mentioned. RESULTS Between 2007 and 2014, we detected the Malaga strain in 30 treatment-naive patients. All were MSM, seen at five hospitals on the Costa del Sol. In all cases, the HIV-1 was subtype B with viral tropism R5. Phylogenetic analysis based on the reverse transcriptase sequence showed consistent grouping (with a bootstrap value of the common node of 100%) of the isolates that shared the mutation pattern mentioned. This strain has not been detected elsewhere or in previously treated patients. All of the patients treated with first-line combination ART responded. CONCLUSIONS We report a cluster of an HIV-1 strain with multiple resistance mutations that was transmitted over a period of >8 years, affecting 30 naive patients from the same geographical area. The strain was susceptible to first-line combination ART.
