CONOCIMIENTO INCORPORADO Y VÍNCULOS INTERSECTORIALES. APROXIMACIONES MEDIANTE EL ANÁLISIS INPUT-OTPUT

Esta tesis doctoral tiene por objetivo el estudio de la actividad innovadora de los sectores económicos desde la perspectiva de los vínculos tecno-productivos que se establecen entre ellos. Dentro de este objetivo general, cobra una destacada importancia el territorio en el cual se encuentran estos sectores, siendo España y la Comunidad Valenciana los casos analizados. Ante estos objetivos, se plantean las siguientes preguntas que guían la investigación: a) ¿Qué rol desempeñan los servicios empresariales intensivos en conocimiento en la generación y difusión de innovación en el sistema económico? ¿Qué contribución cuantitativa realizan tales sectores al sistema de creación y generación de conocimiento? b) ¿Cuáles son los patrones de innovación de sectores menos intensivos en conocimiento, clasificados típicamente como tradicionales, pero con gran arraigo e influencia territorial (en particular el sector agroalimentario)? ¿A qué fuentes recurren con mayor intensidad cuando el territorio presenta también bajas intensidades tecnológicas o baja capacidad de absorción (la Comunidad Valenciana)? c) ¿Qué patrones de innovación se corresponden con distintas capacidades sectoriales para crear nuevas empresas? O en otras palabras, ¿el patrón de generación/absorción de conocimiento de cada sector afecta a su capacidad para crear nuevas empresas? Para dar respuesta a estas preguntas se ha utilizado el enfoque del "embodied knowledge". Esta aproximación permite mensurar el conocimiento "incorporado" en los productos y servicios que cada sector utiliza como inputs en sus procesos productivos y que indirectamente contribuyen a su propia intensidad o esfuerzo tecnológico y de innovación. La metodología implementada puede sintetizarse en la idea de que el mayor o menor grado de esfuerzo innovador en un sector no solo estará determinado por su propio gasto en actividades innovadoras, sino también por el gasto que sus proveedores realizan en estas actividades.Alba, MF.

Innovation and sectoral linkages in the agri-food system in the Valencian Community

This paper aims to analyze the innovative effort of the agri-food system (AFS) in the Valencian Autonomous Community (VC), Spain, estimating the intensity of innovation in each subsector of the AFS. The analysis distinguishes between the direct and indirect (or induced) innovation intensities incorporated by the acquisition of inputs from other subsectors produced in the VC or in the rest of Spain. The methodology employed is based on the input-output framework combined with data of technological innovation in enterprises. This methodology provides the novelty of been applied to a region the VC and not to a country as it is usually done. The results show that the weight of intersectoral flows in the total innovation effort of the AFS is significant with marked differences between primary and food industry. In most activities, embodied knowledge in inputs purchased from Spain is greater than embodied knowledge of inputs produced inside the region.Authors would like to thank the Ministry of Science and innovation for its support for this paper (Project AGRINNOVA; reference: AGL2009-13303-C02-02).García Alvarez-Coque, JM.; Alba ., MF.; López-García Usach, T.

Impact of the sensory experience on consumers’ preference toward the origin of honey: a case study in Mar del Plata, Argentina

This study analysed consumers' expected preference toward local honey with different colour and texture. We analysed the impact of the sensory experience on consumers' expectation and their willingness to pay for the honey products. We carried out two Non-Hypothetical Discrete Choice Experiments (DCE) by creating a real shopping scenario before and after the hedonic sensory test for a sample of 145 consumers from Mar del Plata, Argentina. Data used in this analysis were obtained from questionnaires completed in a controlled environment and estimated using the random parameters Logit model (MIXL). Results showed both high preference and acceptance for local honey with solid texture and light colour and also revealed a high rejection for dark honeys. Consumers also declared their willingness to pay a premium for their most preferred honey type if it is produced from local place. The sensory experience has had impact on expectation. Consumers were not willing to compromise their perceived quality and their eating experience with other descriptors of the honey product.Este estudio analizó la preferencia esperada de los consumidores hacia la miel local con diferentes colores y texturas. Analizamos el impacto de la experiencia sensorial en las expectativas de los consumidores y su disposición a pagar por los productos de miel. Se llevaron a cabo dos Experimentos de Elección Discreta No Hipotética (DCE), creando un escenario real de compra antes y después de la prueba sensorial hedónica para una muestra de 145 consumidores de Mar del Plata, Argentina. Los datos utilizados en este análisis se obtuvieron a partir de cuestionarios completados en un entorno controlado y estimados utilizando el modelo Logit de parámetros aleatorios (MIXL). Los resultados mostraron alta preferencia y aceptación por la miel local con textura sólida y color claro y también revelaron un alto rechazo por las mieles oscuras. Los consumidores también declararon su disposición a pagar una prima por su tipo de miel preferido si se produce en un lugar local. La experiencia sensorial ha tenido un impacto en las expectativas. Los consumidores no estaban dispuestos a comprometer su calidad percibida y su experiencia alimentaria con otros descriptores del producto de miel.Centro de Investigación en Ciencias Políticas, Económicas y SocialesFil: Kallas, Zein.

Composición de la intensidad innovadora de la industria agroalimentaria: fuentes internas y externas

[EN] This paper explores the contribution of different sources of innovation to the total innovation intensity of the food system. The methodology used combines the input-output framework and the Survey on Technological Innovation in Firms data. The paper calculates the embodied innovation intensity contained in the inputs purchased by the agri food system in a region distinguishing the inputs by its origin. This approach has been applied to the Valencian food system that shows a lower intensity of innovation than the Spanish food s ystem and some impact in the generation of knowledge in the region. The innovation intensity estimated for the food industry is 6 times larger than the innovation intensity of the primary sector and the interior technological multiplier is 61% of the total technological multiplier.[ES] Este trabajo investiga la contribución de distintas fuentes a la intensidad de innovación total de la industria agroalimentaria mediante una aproximación que combina el marco input-output con datos de la Encuesta de Innovación Tecnológica en Empresas. El artículo estima los flujos de innovación incorporada en los insumos que adquiere este sistema, con especial atención a los que recibe del exterior. El enfoque se ha aplicado al caso del sistema agroalimentario valenciano que muestra una intensidad de innovación menor que la media española y cierto impacto como inductor de conocimiento en la región. La industria alimentaria presenta un esfuerzo innovador 6 veces mayor al del sector primario y un considerable esfuerzo tecnológico sobre la economía regional, siendo su multiplicador tecnológico interior el 61 por ciento del multiplicador tecnológico total.Los autores agradecen el apoyo financiero del ministerio de economía y competitividad (proyecto formas de organizacion de la innovacion en el sistema agroalimentario referencia: agl2012-39793-c03-02).López-García Usach, T.; García Alvarez-Coque, JM.; Alba, MF.

IL-10-Dependent and -Independent Mechanisms Are Involved in the Cardiac Pathology Modulation Mediated by Fenofibrate in an Experimental Model of Chagas Heart Disease

IL-10 is an anti-inflammatory cytokine that plays a significant role in the modulation of the immune response in many pathological conditions, including infectious diseases. Infection with Trypanosoma cruzi (T. cruzi), the etiological agent of Chagas disease, results in an ongoing inflammatory response that may cause heart dysfunction, ultimately leading to heart failure. Given its infectious and inflammatory nature, in this work we analyzed whether the lack of IL-10 hinders the anti-inflammatory effects of fenofibrate, a PPARα ligand, in a murine model of Chagas heart disease (CHD) using IL-10 knockout (IL-10 KO) mice. Our results show fenofibrate was able to restore the abnormal cardiac function displayed by T. cruzi-infected mice lacking IL-10. Treatment with fenofibrate reduced creatine kinase (CK) levels in sera of IL-10 KO mice infected with T. cruzi. Moreover, although fenofibrate could not modulate the inflammatory infiltrates developing in the heart, it was able to reduce the increased collagen deposition in infected IL-10 KO mice. Regarding pro-inflammatory mediators, the most significant finding was the increase in serum IL-17. These were reduced in IL-10 KO mice upon fenofibrate treatment. In agreement with this, the expression of RORγt was reduced. Infection of IL-10 KO mice increased the expression of YmI, FIZZ and Mannose Receptor (tissue healing markers) that remained unchanged upon treatment with fenofibrate. In conclusion, our work emphasizes the role of anti-inflammatory mechanisms to ameliorate heart function in CHD and shows, for the first time, that fenofibrate attains this through IL-10-dependent and -independent mechanisms.Fil: Rada, Maria Jimena.

External validity of clinical trials with diverse trastuzumab-based chemotherapy regimens in advanced gastroesophageal adenocarcinoma: data from the AGAMENON-SEOM registry

Background: Trastuzumab combined with cisplatin and fluoropyrimidines, either capecitabine or 5-fluorouracile (XP/FP), is the standard first-line treatment for advanced, HER2-positive, gastric cancer patients based on the ToGA trial. Despite the lack of phase III trials, many clinicians administer trastuzumab with alternative regimens. One meta-analysis suggests that substituting cisplatin for oxaliplatin might lead to greater efficacy and less toxicity. Methods: 594 patients with HER2-positive gastroesophageal adenocarcinoma were recruited from the AGAMENON-SEOM registry. The objective was to evaluate the external validity of clinical trials with chemotherapy and trastuzumab. Results: The regimens used in at least 5% of the patients were XP (27%), oxaliplatin and capecitabine (CAPOX) (26%), oxaliplatin and 5-fluorouracil (FOLFOX) (14%), FP (14%), triplet with anthracycline/docetaxel (7%), and carboplatin-FU (5%). Median exposure to trastuzumab was longer with FOLFOX (11.4 months, 95% CI, 9.1-21.0) versus ToGA regimens (7.5, 6.4-8.5), p < 0.001. Patients with HER2-IHC 3+ cancers had higher response rates than those with IHC 2+/FISH+, odds-ratio 1.97 (95% CI, 1.25-3.09). The results achieved with CAPOX-trastuzumab were comparable to those attained with ToGA regimens. FOLFOX-trastuzumab was superior to ToGA schemes in terms of overall survival (OS), with a greater magnitude of effect in IHC 2+/FISH+ tumors (HR 0.47, 0.24-0.92) compared with IHC 3+ (HR 0.69, 0.49-0.96), and in diffuse (HR 0.37, 0.20-0.69) versus intestinal-type tumors (HR 0.76, 0.54-1.06). Conclusion: We have updated the external validity of clinical trials with trastuzumab in first-line treatment of gastric cancer. Our data confirm the comparable outcomes of ToGA regimens and CAPOX-trastuzumab in clinical practice and point toward a possible benefit of FOLFOX-trastuzumab, contingent on the subtypes typically less sensitive to trastuzumab, to be confirmed in clinical trials

Risk Factors for COVID-19 in Inflammatory Bowel Disease: A National, ENEIDA-Based Case–Control Study (COVID-19-EII)

(1) Scant information is available concerning the characteristics that may favour the acquisition of COVID-19 in patients with inflammatory bowel disease (IBD). Therefore, the aim of this study was to assess these differences between infected and noninfected patients with IBD. (2) This nationwide case-control study evaluated patients with inflammatory bowel disease with COVID-19 (cases) and without COVID-19 (controls) during the period March-July 2020 included in the ENEIDA of GETECCU. (3) A total of 496 cases and 964 controls from 73 Spanish centres were included. No differences were found in the basal characteristics between cases and controls. Cases had higher comorbidity Charlson scores (24% vs. 19%; p = 0.02) and occupational risk (28% vs. 10.5%; p < 0.0001) more frequently than did controls. Lockdown was the only protective measure against COVID-19 (50% vs. 70%; p < 0.0001). No differences were found in the use of systemic steroids, immunosuppressants or biologics between cases and controls. Cases were more often treated with 5-aminosalicylates (42% vs. 34%; p = 0.003). Having a moderate Charlson score (OR: 2.7; 95%CI: 1.3-5.9), occupational risk (OR: 2.9; 95%CI: 1.8-4.4) and the use of 5-aminosalicylates (OR: 1.7; 95%CI: 1.2-2.5) were factors for COVID-19. The strict lockdown was the only protective factor (OR: 0.1; 95%CI: 0.09-0.2). (4) Comorbidities and occupational exposure are the most relevant factors for COVID-19 in patients with IBD. The risk of COVID-19 seems not to be increased by immunosuppressants or biologics, with a potential effect of 5-aminosalicylates, which should be investigated further and interpreted with caution

Nirmatrelvir/ritonavir in COVID-19 patients with haematological malignancies: a report from the EPICOVIDEHA registry

Background: Nirmatrelvir/ritonavir treatment decreases the hospitalisation rate in immunocompetent patients with COVID-19, but data on efficacy in patients with haematological malignancy are scarce. Here, we describe the outcome of nirmatrelvir/ritonavir treatment in a large cohort of the latter patients. Methods: This is a retrospective cohort study from the multicentre EPICOVIDEHA registry (NCT04733729) on patients with haematological malignancy, who were diagnosed with COVID-19 between January and September 2022. Patients receiving nirmatrelvir/ritonavir were compared to those who did not. A logistic regression was run to determine factors associated with nirmatrelvir/ritonavir administration in our sample. Mortality between treatment groups was assessed with Kaplan-Meier survival plots after matching all the patients with a propensity score. Additionally, a Cox regression was modelled to detect factors associated with mortality in patients receiving nirmatrelvir/ritonavir. Findings: A total of 1859 patients were analysed, 117 (6%) were treated with nirmatrelvir/ritonavir, 1742 (94%) were treated otherwise. Of 117 patients receiving nirmatrelvir/ritonavir, 80% had received ≥1 anti-SARS-CoV-2 vaccine dose before COVID-19 onset, 13% of which received a 2nd vaccine booster. 5% were admitted to ICU. Nirmatrelvir/ritonavir treatment was associated with the presence of extrapulmonary symptoms at COVID-19 onset, for example anosmia, fever, rhinitis, or sinusitis (aOR 2.509, 95%CI 1.448-4.347) and 2nd vaccine booster (aOR 3.624, 95%CI 1.619-8.109). Chronic pulmonary disease (aOR 0.261, 95%CI 0.093-0.732) and obesity (aOR 0.105, 95%CI 0.014-0.776) were not associated with nirmatrelvir/ritonavir use. After propensity score matching, day-30 mortality rate in patients treated with nirmatrelvir/ritonavir was 2%, significantly lower than in patients with SARS-CoV-2 directed treatment other than nirmatrelvir/ritonavir (11%, p&nbsp;=&nbsp;0.036). No factor was observed explaining the mortality difference in patients after nirmatrelvir/ritonavir administration. Interpretation: Haematological malignancy patients were more likely to receive nirmatrelvir/ritonavir when reporting extrapulmonary symptoms or 2nd vaccine booster at COVID-19 onset, as opposed to chronic pulmonary disease and obesity. The mortality rate in patients treated with nirmatrelvir/ritonavir was lower than in patients with targeted drugs other than nirmatrelvir/ritonavir. Funding: EPICOVIDEHA has received funds from Optics COMMIT (COVID-19 Unmet Medical Needs and Associated Research Extension) COVID-19 RFP program by GILEAD Science, United States (Project 2020-8223)

Age, Successive Waves, Immunization, and Mortality in Elderly COVID-19 Haematological Patients: EPICOVIDEHA Findings

Introduction: elderly patients with haematologic malignancies face the highest risk of severe COVID-19 outcomes. The infection impact in different age groups remains unstudied in detail. Methods: We analysed elderly patients (age groups: 65-70, 71-75, 76-80 and &gt;80 years old) with hematologic malignancies included in the EPICOVIDEHA registry between January 2020 and July 2022. Univariable and multivariable Cox regression models were conducted to identify factors influencing death in COVID-19 patients with haematological malignancy. results: the study included data from 3,603 elderly patients (aged 65 or older) with haematological malignancy, with a majority being male (58.1%) and a significant proportion having comorbidities. The patients were divided into four age groups, and the analysis assessed COVID-19 outcomes, vaccination status, and other variables in relation to age and pandemic waves.tThe 90-day survival rate for patients with COVID-19 was 71.2%, with significant differences between groups. The pandemic waves had varying impacts, with the first wave affecting patients over 80 years old, the second being more severe in 65-70, and the third being the least severe in all age groups. factors contributing to 90-day mortality included age, comorbidities, lymphopenia, active malignancy, acute leukaemia, less than three vaccine doses, severe COVID-19, and using only corticosteroids as treatment. Conclusions: These data underscore the heterogeneity of elderly haematological patients, highlight the different impact of COVID waves and the pivotal importance of vaccination, and may help in planning future healthcare efforts

First Latin American clinical practice guidelines for the treatment of systemic lupus erythematosus: Latin American Group for the Study of Lupus (GLADEL, Grupo Latino Americano de Estudio del Lupus)-Pan-American League of Associations of Rheumatology (PANLAR)

Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents a significant challenge for both diagnosis and treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice guidelines for Latin American patients with lupus. Two independent teams (rheumatologists with experience in lupus management and methodologists) had an initial meeting in Panama City, Panama, in April 2016. They selected a list of questions for the clinical problems most commonly seen in Latin American patients with SLE. These were addressed with the best available evidence and summarised in a standardised format following the Grading of Recommendations Assessment, Development and Evaluation approach. All preliminary findings were discussed in a second face-to-face meeting in Washington, DC, in November 2016. As a result, nine organ/system sections are presented with the main findings; an 'overarching' treatment approach was added. Special emphasis was made on regional implementation issues. Best pharmacologic options were examined for musculoskeletal, mucocutaneous, kidney, cardiac, pulmonary, neuropsychiatric, haematological manifestations and the antiphospholipid syndrome. The roles of main therapeutic options (ie, glucocorticoids, antimalarials, immunosuppressant agents, therapeutic plasma exchange, belimumab, rituximab, abatacept, low-dose aspirin and anticoagulants) were summarised in each section. In all cases, benefits and harms, certainty of the evidence, values and preferences, feasibility, acceptability and equity issues were considered to produce a recommendation with special focus on ethnic and socioeconomic aspects. Guidelines for Latin American patients with lupus have been developed and could be used in similar settings.Fil: Pons Estel, Bernardo A..
