Background/Objectives: To date, nearly 300 lentiviral-based gene therapy clinical trials have been conducted, with eight therapies receiving regulatory approval for commercialization. These advances, along with the increased number of advanced-phase clinical trials, have prompted contract development and manufacturing organizations (CDMOs) to develop innovative strategies to address the growing demand for large-scale batches of lentiviral vectors (LVVs). Consequently, manufacturers have focused on optimizing processes under good manufacturing practices (GMPs) to improve cost-efficiency, increase process robustness, and ensure regulatory compliance. Nowadays, the LVV production process mainly relies on the transient transfection of four plasmids encoding for the lentiviral helper genes and the transgene. While this method is efficient at small scales and has also proven to be scalable, the industry is exploring alternative processes due to the high cost of GMP reagents, and the batch-to-batch variability predominantly attributed to the transfection step. Methods: Here, we report the development and implementation of a reliable and clinical-grade envisioned platform based on the generation of stable producer cell lines (SCLs) from an initial well-characterized lentiviral packaging cell line (PCL). Results: This platform enables the production of VSV-G-pseudotyped LVVs through a fully transfection-free manufacturing process. Our data demonstrate that the developed platform will facilitate successful technological transfer to large-scale LVV production for clinical application. Conclusions: With this simple and robust stable cell line generation strategy, we address key concerns associated with the costs and reproducibility of current manufacturing processes.

LOW density lipoprotein receptors ,PRODUCTION losses ,GENE therapy ,GENETIC transduction ,MANUFACTURING processes - Abstract
Transduction of producer cells during lentiviral vector (LVV) production causes the loss of 70–90% of viable particles. This process is called retro-transduction and it is a consequence of the interaction between the LVV envelope protein, VSV-G, and the LDL receptor located on the producer cell membrane, allowing lentiviral vector transduction. Avoiding retro-transduction in LVV manufacturing is crucial to improve net production and, therefore, the efficiency of the production process. Here, we describe a method for quantifying the transduction of producer cells and three different strategies that, focused on the interaction between VSV-G and the LDLR, aim to reduce retro-transduction.

- Abstract
Si bien es costoso trasladar las operaciones fuera de China, muchas empresas están considerando hacerlo porque hacer negocios allí se está volviendo más costoso debido al aumento de los costos laborales y la amenaza constante del robo de propiedad intelectual. Otros factores que impulsan la salida de empresas de China incluyen la pandemia del coronavirus, la volatilidad del mercado, el conflicto en Ucrania, la interrupción de las cadenas de suministro globales y los temores de una guerra comercial entre China y EE. UU., el mayor importador del mundo. Debido a esto, algunas empresas estadounidenses se han reubicado o tienen la intención de reubicar sus operaciones de abastecimiento y producción fuera de China, utilizando el modelo de producción de proximidad llamado nearshoring. Por estas razones, el objetivo de este documento es determinar, a través de un estudio de análisis de caso, si es factible que las empresas estadounidenses que se especializan en la industria textil y de confecciones adopten procesos empresariales con un enfoque de regionalización, es decir, que puedan trasladar las empresas desde China a América Latina, específicamente en países como Brasil, Colombia, México o El Salvador. La metodología de esta tesis se basa en un enfoque de métodos mixtos. La metodología cualitativa incluye entrevistas no estructuradas a expertos del sector manufacturero y la cuantitativa incluye la recolección y análisis documental estadístico de los vínculos comerciales entre los países estudiados y EE.UU., las ventajas y desventajas en caso de que se consideren un destino de nearshoring, así como el estado actual de las industrias textiles y de confección en cada uno de ellos., Although moving operations out of China is expensive, many businesses are considering it because doing business there is becoming more expensive due to rising labor costs and the ongoing threat of intellectual property theft. Other factors driving business out of China include coronavirus pandemic, market volatility, the conflict in Ukraine, the disruption of global supply chains, and fears of a trade war between China and the US, the world's largest importer. Due to this, US businesses have relocated or intend to relocate their sourcing and production operations outside China, utilizing the nearshoring production model. Therefore, the objective of this document is to determine, through a case analysis study, if it is feasible for US companies that specialize in the textile and apparel industry to adopt business processes with a regionalization approach, that is, which can relocate companies from China to Latin America, specifically in countries such as Brazil, Colombia, Mexico or El Salvador. The methodology of this thesis is based on a mixed methods approach. The qualitative methodology includes unstructured interviews with experts from the manufacturing sector and the quantitative methodology includes the collection and statistical documentary analysis of the commercial links between the countries studied and the US, the advantages, and disadvantages in case they are considered a nearshoring destination, as well as the current state of the textile and clothing industries in each of them.

The increasing spread of Aedes (Stegomyia) albopictus (Skuse, 1894)—commonly known as the Asian tiger mosquito and potential vector of various arboviruses —along the Spanish Mediterranean coast and the intense traffic between this area and the Community of Madrid had increased the risk of its arrival in the latter region. Thus, in 2016 the Community of Madrid’s Health Department set up a program for the entomological surveillance and environmental health control of vectors that transmit arboviruses (dengue, chikungunya and zika).The aim of this paper is to analyze the information obtained in the course of this program from 2016 till 2020. Entomological surveillance was designed along the big axes formed by the radial highways that link Madrid with the Mediterranean coast. This active surveillance consisted in installing lethal ovitraps and looking for larvae hatcheries. This was complemented with passive, citizen-based surveillance via channels such as Mosquito Alert. In the summer of 2017, eggs resembling those of Ae. albopictus were found in a trap installed at a gas station on the N-III Highway. In 2018, two persons respectively submitted photos of adult mosquitoes they had seen in two municipalities of the Community of Madrid—Velilla de San Antonio and Rivas- Vaciamadrid, which were later confirmed to belong to this species by the Entomology Laboratory of the Complutense University of Madrid’s Biological Sciences Faculty. Subsequent entomological surveillance in these two municipalities showed that the Asian tiger mosquito had already settled in the former but not in latter. However, a second reintroduction apparently occurred in 2020, the presence of this species being confirmed in Rivas-Vaciamadrid. La creciente implantación de Aedes (Stegomyia) albopictus (Skuse, 1894), vector potencial de varias arbovirosis, comúnmente conocido como mosquito tigre, en el litoral mediterráneo y el gran tráfico existente entre esos lugares y la Comunidad de Madrid, aumentaba el riesgo de su llegada a la región. Por ello, esta Comunidad estableció, en el año 2016, el Programa de Vigilancia Entomológica y Control Sanitario-Ambiental de Vectores Transmisores de Arbovirus (dengue, chikungunya y zika). El objetivo de este manuscrito es analizar la información obtenida desde su puesta en marcha en 2016 hasta 2020. La vigilancia entomológica se diseñó en torno a los grandes ejes de las carreteras que comunican Madrid con el Mediterráneo. Esta vigilancia activa se realiza mediante la colocación de trampas de oviposición, de adultos y la prospección de criaderos larvarios. Se complementa mediante vigilancia pasiva con dispositivos como Mosquito Alert. En verano del 2017 se detectó la presencia de huevos compatibles con Ae. albopictus en una trampa ubicada en una gasolinera de la Nacional III. En el 2018, dos ciudadanos remitieron sendas fotos de mosquitos adultos encontrados en dos municipios de la Comunidad de Madrid, Velilla de San Antonio y Rivas-Vaciamadrid, que fueron confirmados por el laboratorio de entomología de la Facultad de Ciencias Biológicas (Universidad Complutense de Madrid), como Ae. albopictus. El seguimiento entomológico posterior en estos dos municipios refleja el establecimiento del mosquito tigre en el primer municipio que no se confirmó en Rivas en 2018, pero sí en 2020 cuando aparentemente se produjo una segunda reintroducción. A crescente implantação de Aedes (Stegomyia) albopictus (Skuse, 1894), vetor potencial de vários arbovírus e comummente conhecido como mosquito tigre, no litoral mediterrâneo, e o grande tráfego existente entre estes lugares e a Comunidade de Madrid, aumentou o risco da sua chegada à região. Por essa razão, a Comunidade de Madrid estabeleceu, no ano de 2016, o Programa de Vigilância Entomológica e Controlo Sanitário-Ambiental de Vetores Transmissores de Arbovírus (dengue, chikungunya e zika). O objetivo desde artigo é analisar a informação obtida desde o início no ano de 2016 até ao ano de 2020. A vigilância entomológica foi desenhada em torno dos eixos principais das estradas radiais que ligam Madrid ao Mediterrâneo. Esta vigilância ativa realiza- se mediante a colocação de armadilhas de oviposição, de adultos e a prospeção de criadouros de larvas. É complementada com dispositivos como o Mosquito Alert. No verão de 2017 detetou-se a presença de ovos compatíveis com Ae. albopictus numa armadilha localizada num posto de combustível na Nacional III. No ano de 2018, dois cidadãos enviaram fotografias de mosquitos adultos encontrados em dois municípios da Comunidade de Madrid, Velilla de San Antonio y Rivas-Vaciamadrid, que foram confirmados em laboratório de entomologia da Faculdade de Ciências Biológicas da Universidade Complutense de Madrid, como Ae. albopictus. A monitorização entomológica subsequente nesses dois municípios reflete o estabelecimento do mosquito tigre no primeiro município, o que não foi confirmado em Rivas em 2018, mas sim em 2020, quando uma segunda reintrodução aparentemente ocorreu.

Nefropatía ,Biomarcadores ,Hiperglucemia ,Insuficiencia - Abstract
La nefropatía diabética es una complicación crónica de la diabetes mellitus, de gran prevalencia a nivel mundial y nacional, caracterizada por la disminución de la filtración glomerular y es producto de mecanismos fisiopatológicos que generan cambios a nivel micro y macroscópicos a nivel renal, causando daños irreparables en etapas avanzada. El objetivo de la presente revisión es describir los factores de riesgo de nefropatía diabética en adultos, en base a literatura actualizada, referente a medicina basada en la evidencia. Se realizó una revisión bibliográfica, utilizando la base de datos Pubmed, Scielo, Google Académico, Elsevier, Medigraphic. Los resultados de esta investigación, demostraron que los principales factores de riesgo son hiperglucemia e hipertensión arterial, mal controlada, evolucionando a insuficiencia renal crónica, con morbilidad y mortalidad importante, por lo que su diagnóstico temprano es de vital importancia para evitar su aparición. Los biomarcadores más usados para su detección son la creatinina sérica, microalbuminuria y la tasa de filtración glomerular.

β-hemoglobinopathies, including β-thalassemia and sickle cell disease (SCD), are autosomal recessive inherited disorders caused by various mutations in the β-globin gene. The most effective curative therapy involves allogenic hematopoietic stem cell transplantation (HSCT) from an immunologically-matched donor. However, this approach presents some limitations in terms of finding a suitable donor and transplantation related risks, such as a graft-versus-host disease (GvHD). In this thesis, we strongly emphasized that autologous HSCT in combination with gene therapy tools will develop novel treatments for β-hemoglobinopathies. A promising technique for gene editing has emerged in recent years based on the use of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) -associated RNA-guided endonuclease Cas9 (CRISPR/Cas9) technology. This revolutionary tool enables to perform gene disruption, gene correction, and gene addition in a specific locus of interest with high reliability and efficiency. Through this technology, in our first study, we demonstrated that targeting KLF1 and BCL11A, which control the expression of γ-globin, as well as the promoter region of HBG1 and HBG2 (HBG1/2), resulted in upregulation of γ-globin gene expression and fetal hemoglobin (HbF). Furthermore, after a deep comparison between the three gene editing strategies, we confirmed that BCL11A approach, which is currently in clinical phase, is the safest gene therapy treatment for β-hemoglobinopathies. Nevertheless, HBG1/2 strategy also holds potential for clinical translation. Alternatively, since β-globin gene correction is also a feasible gene therapy approach, in our second study, we attained successfully gene addition in HSPCs by inserting a NheI-tag at the common aberrant splicing mutation point, HBB IVS1-110 by means of Cas9 mRNA and ssODN electroporation. In the last project, we thoroughly compared three lentiviral transgenes encoding for IGF2BP1, shRNA BCL11A, and ꝩ-globin to reactivate HbF production in HSPCs. Also, we assessed whether baboon envelope proteins (BaEV and BaEV-RLess) have a beneficial advantage over the regularly used vesicular-stomatitis-virus-G envelope protein (VSV-G). Our results showed 4 that all treatments using VSV-G envelope proteins resulted in therapeutic levels of HbF. In addition, baboon envelopes, especially BaEV-RLess, achieved decent levels of HbF with less viral particles, which might ameliorate the symptoms of the disease. Finally, even though IGF2BP1 and BCL11A approaches induced higher HbF levels than ꝩ-globin strategy, their role in gene regulation might cause undesired iatrogenic effects. Therefore, we considered ꝩ-globin the best lentiviral gene therapy strategy for the treatment of β-hemoglobinopathies. During this thesis we evidenced that both gene therapy tools, lentiviral gene transfer and genome editing, provide a successful platform for gene treatment of blood disorders. In addition to the current clinical trial approaches, we strongly believe that resurgence of HbF is the most straight forward strategy together with β-globin gene correction. However, due to the low occurrence of gene correction events in HSPCs, further investigation is required.

- Abstract
The increasing spread of Aedes (Stegomyia) albopictus (Skuse, 1894)—commonly known as the Asian tiger mosquito and potential vector of various arboviruses —along the Spanish Mediterranean coast and the intense traffic between this area and the Community of Madrid had increased the risk of its arrival in the latter region. Thus, in 2016 the Community of Madrid’s Health Department set up a program for the entomological surveillance and environmental health control of vectors that transmit arboviruses (dengue, chikungunya and zika).The aim of this paper is to analyze the information obtained in the course of this program from 2016 till 2020. Entomological surveillance was designed along the big axes formed by the radial highways that link Madrid with the Mediterranean coast. This active surveillance consisted in installing lethal ovitraps and looking for larvae hatcheries. This was complemented with passive, citizen-based surveillance via channels such as Mosquito Alert. In the summer of 2017, eggs resembling those of Ae. albopictus were found in a trap installed at a gas station on the N-III Highway. In 2018, two persons respectively submitted photos of adult mosquitoes they had seen in two municipalities of the Community of Madrid—Velilla de San Antonio and Rivas- Vaciamadrid, which were later confirmed to belong to this species by the Entomology Laboratory of the Complutense University of Madrid’s Biological Sciences Faculty. Subsequent entomological surveillance in these two municipalities showed that the Asian tiger mosquito had already settled in the former but not in latter. However, a second reintroduction apparently occurred in 2020, the presence of this species being confirmed in Rivas-Vaciamadrid., La creciente implantación de Aedes (Stegomyia) albopictus (Skuse, 1894), vector potencial de varias arbovirosis, comúnmente conocido como mosquito tigre, en el litoral mediterráneo y el gran tráfico existente entre esos lugares y la Comunidad de Madrid, aumentaba el riesgo de su llegada a la región. Por ello, esta Comunidad estableció, en el año 2016, el Programa de Vigilancia Entomológica y Control Sanitario-Ambiental de Vectores Transmisores de Arbovirus (dengue, chikungunya y zika). El objetivo de este manuscrito es analizar la información obtenida desde su puesta en marcha en 2016 hasta 2020. La vigilancia entomológica se diseñó en torno a los grandes ejes de las carreteras que comunican Madrid con el Mediterráneo. Esta vigilancia activa se realiza mediante la colocación de trampas de oviposición, de adultos y la prospección de criaderos larvarios. Se complementa mediante vigilancia pasiva con dispositivos como Mosquito Alert. En verano del 2017 se detectó la presencia de huevos compatibles con Ae. albopictus en una trampa ubicada en una gasolinera de la Nacional III. En el 2018, dos ciudadanos remitieron sendas fotos de mosquitos adultos encontrados en dos municipios de la Comunidad de Madrid, Velilla de San Antonio y Rivas-Vaciamadrid, que fueron confirmados por el laboratorio de entomología de la Facultad de Ciencias Biológicas (Universidad Complutense de Madrid), como Ae. albopictus.

- Abstract
In Chagas disease (ChD) caused by Trypanosoma cruzi, new biomarkers to predict chronic cardiac pathology are urgently needed. Previous studies in chagasic patients with mild symptomatology showed that antibodies against the immunodominant R3 epitope of sCha, a fragment of the human basic helix-loop-helix transcription factor like 5, correlated with cardiac pathology. To validate sCha as a biomarker and to understand the origin of anti-sCha antibodies, we conducted a multicenter study with several cohorts of chagasic patients with severe cardiac symptomatology. We found that levels of antibodies against sCha discriminated the high risk of sudden death, indicating they could be useful for ChD prognosis. We investigated the origin of the antibodies and performed an alanine scan of the R3 epitope. We identified a minimal epitope MRQLD, and a BLAST search retrieved several T. cruzi antigens. Five of the hits had known or putative functions, of which phosphonopyruvate decarboxylase showed the highest cross-reactivity with sCha, confirming the role of molecular mimicry in the development of anti-sCha antibodies. Altogether, we demonstrate that the development of antibodies against sCha, which originated by molecular mimicry with T. cruzi antigens, could discriminate electrocardiographic alterations associated with a high risk of sudden death.

RESUMEN Fundamentos: La leishmaniasis en una enfermedad zoonótica muy extendida a nivel mundial y es endémica en algunas regiones de España. Desde 2009 un brote de leishmaniasis ha afectado a algunos municipios del sur de Madrid con características e implicaciones especiales en cuanto a epidemiología, reservorio e intervención medioambiental. Se ha observado un aumento de casos en las zonas rurales adyacentes con características ambientales similares. El objetivo de este trabajo fue estudiar y analizar la evolución de los casos de leishmaniasis declarados en una zona rural colindante y compararlos con el brote comunitario. Métodos: Se utilizó la información de los casos declarados a la Red de Vigilancia Epidemiológica de la Comunidad de Madrid en la zona de estudio desde 2001-2017 y se compararon las tasas de incidencia con las del área del brote. Se realizó un análisis espacial de los casos y de los conglomerados para cuatro unidades espaciales. Se realizó análisis de conglomerados según la técnica de Kulldorff y análisis de puntos calientes según Gi* de Getis-Ord. Se relacionó la información disponible de lepóridos y vectores con la ubicación de los casos. Resultados: Los casos observados en el área de estudio superaron a los esperados tras al inicio del brote (índice epidémico 7,8 en 2013) mostrándose una relación gráfica entre las tasas de incidencia. Existió una auto-correlación espacial cuando se analizaron el número de casos por secciones censales y por cuadrículas (índice de Moran de 0,208; z= 9,336). En el análisis de puntos calientes se pudo apreciar una mayor incidencia en el área de estudio en el periodo posterior al brote, en particular en la Zona Básica de Salud de Griñón. Se constató una relación espacial entre casos y zonas de mayor presencia de lepóridos y vectores. Conclusión: La distribución de casos de leishmaniasis en el periodo y área de estudio sugiere que puede existir una asociación entre el brote comunitario y el aumento de casos de los últimos años en el área de estudio, específicamente en la zona rural, por lo que sería necesario reforzar la vigilancia y aplicar medidas de control ambiental en caso necesario, lo cual puede contribuir a limitar la extensión del brote. ABSTRACT Background: Leishmaniasis is a zoonotic disease, widely spread all over the world, and an endemic disease in some Spanish regions. Within the Autonomous Region of Madrid, some south populations were affected by an outbreak from 2009. This outbreak had special features and implications related to epidemiology, reservoir and environment intervention. An increased rate in rural areas bordering the outbreak area was detected by epidemiological surveillance. This area has the same environment characteristics. The objective of this study was to research and analyze the evolution of leishmaniasis cases declared in a rural area and their comparison with the cases of the outbreak area. Methods: The cases declared to Epidemiology Surveillance Network have been used. Kulldorff´s tools were used for the cluster analysis. A hot spot analysis (Getis-Ord Gi*) was made. Leporidae and vector information of the area was related to the location of cases. Results: The number of observed cases exceeded the number of expected cases in this area (epidemic index 7.8 in 2013), after the outbreak. This showed a relation between both incidence rates. It seemed to be spatial correlation when the number of cases was analyzed by census sections and grids (Moran´s I 0,208; z= 9,336). Using the hot-spot analysis, a higher incidence of the study area could be observed, and within Health Basic Area of Griñón after the outbreak years. A spatial relation between cases and a greater presence of vectors and leporidae was found. Conclusion: The distribution of leishmaniasis cases, in the period and study area suggests a link between the community outbreak and the increase of cases in the study area last years, overall in the rural area. It would be useful to strengthen surveillance and it should apply effective measures used in the bordering area if they were necessary. These measures can help to control the spread of the outbreak.

- Abstract
Los valores de referencia de hemoglobina de la Organización Mundial de la Salud (OMS) subestiman la prevalencia de la anemia nutricional por carencia de hierro en las poblaciones andinas. Tal es la conclusión de la investigación que hemos realizado para evaluar el estado de algunos indicadores hematológicos, entre ellos hemoglobina, en 126 habitantes de la zona andina ecuatoriana, de ambos sexos, aparentemente en buen estado de salud y pertenencientes a diferentes grupos etarios. 30 pre—escolares, 50 escolares y 46 adultos jóvenes participaron en el estudio. En el primer día de la investigación se encontró que, de acuerdo a los valores de referencia de la OMS corregidos para la altura de Quito, 85 individuos debían ser considerados no—anémicos, vale decir “normales” . Al cabo de un período de suplementación con hierro, se halló que 27 de los 85 sujetos, esto es un 32 por ciento, habían incrementado su valor de hemoglobina al menos en lg/dl. En consecuencia se trataba de individuos verdaderamente anémicos y por ende deficientes en hierro, quienes, de no mediar la prueba de suplementación, se hubiesen mantenido en la categoría de “normales” , subestimándose la_prevalencia en el porcentaje indicado.

Cultural intelligence (CI) has often been linked to performance at the individual, team, and firm levels as a key factor in international business success. Using a new measure of CI, the business cultural intelligence quotient (BCIQ), our study provides empirical evidence on several key antecedents of CI using data on business professionals across five diverse countries (Austria, Colombia, Greece, Spain, and the United States). The findings suggest that the most important factors leading to cultural intelligence, in order of importance, are the number of countries that business practitioners have lived in for more than six months, their level of education, and the number of languages spoken. We find that cultural intelligence varies across countries, suggesting that some countries have a higher propensity for cross‐cultural business interactions. By teasing out the common antecedents of BCIQ among professionals, our findings may help with screening and training professionals for international assignments. Future research may examine the environmental (country‐specific) factors associated with a higher propensity for cultural intelligence (such as immigration, cultural diversity, languages spoken, and international trade) to explain the effect of country of origin on cultural intelligence in the professional community. © 2016 Wiley Periodicals, Inc.
