Abstract The photoluminescent behavior of Eu-doped Sr3Al2O6 obtained by highly efficient solution combustion synthesis is reported. In order to understand the influence of the fuel on the synthesis, the stoichiometric quantity and an excess of fuel were evaluated. By adjusting the amount of fuel, different luminescence responses were obtained, allowing europium cations incorporation into the Sr3Al2O6 lattice to serve as effective luminescence activators in such a short time during the rapid combustion synthesis process. The higher amount of fuel in the presence of the oxidizing agent produced Sr3Al2O6:Eu particles with higher phosphorescence brightness, owing to the increase of the reduction process from Eu3+ to Eu2+. The synthesized phosphor showed an intense band emission centered at 515 nm and could be excited over a broad spectral range in the UV-visible region. Particles having nanostructured flake-type morphology were obtained, which was considered a micro-nanofunctional candidate for practical applications.

Abstract In this paper, we show the results of the analysis by the SIMS method of mouse fibroblast cells (3T3-F44A2 line) grown on the silicon surface and fixed by using different chemicals. Ion images of the distribution of chemical elements inside cells with a sufficiently high lateral resolution were obtained, allowing us to study, among other things, the internal structure of cells. It was concluded that the standard method of dehydration and fixation of cells with the help of glutaraldehyde allows us to prepare relevant samples for analysis by the SIMS method in ultrahigh vacuum. The use of SIMS looks preferable for the analysis of cellular metabolism, cell differentiation, ischemia and other processes in cells and tissues grown using special medications and (or) reagents with an artificial isotopic composition of stable isotopes.

Abstract Chenopodium quinoa Willd. it is an Andean cereal of great importance for human consumption due to its high nutritional value. In Colombia there is a high phenotypic and genotypic variability within quinoa crops, which has not been studied and has been maintained by the same farmers cycle after production cycle. The objective of this study was to carry out an interpopulation characterization of quinoa cultivated in different producing municipalities of the department of Boyacá, in Colombia, for which 19 morphological descriptors were used, which were evaluated in situ in nine municipalities and analyzed through descriptive statistics, principal component analysis, correlation and conglomerates. In the evaluation of the quantitative traits for all the populations, it was observed that the most variable descriptors were Number of teeth lower leaf (DHI), Lower leaf length (LHI), Width upper leaf (AHI) and Number of teeth upper leaf (DHS). Great segregation between and within individuals of Blanca de Jericó and Piartal was observed for panicle and leaf color and shape, stem color, presence of teeth, and axils on upper and lower leaves. A classification key is proposed that allows in the field to be able to morphologically differentiate the genotypes of Piartal and Blanca de Jericó. This research shows that among the most cultivated genotypes in the department of Boyacá, there is still an important phenotypic diversity given at the inter and intra-individual level, due to the phenological state and the agroclimatological conditions of the different producing regions.

Resumo Chenopodium quinoa Willd. é um cereal andino de grande importância para a alimentação humana por causa do seu alto valor nutricional. Na Colômbia, existe uma alta variabilidade fenotípica e genotípica nos cultivos de quinoa, que não foi estudada e tem sido mantida pelo mesmo produtor ciclo após ciclo de produção. O objetivo deste estudo foi realizar uma caracterização interpopulacional da quinoa cultivada em diferentes municípios produtores do departamento de Boyacá, na Colômbia. Para tanto, foram utilizados 19 descritores morfológicos, avaliados in situ em nove municípios e analisados por meio de estatísticas descritivas, análise de componentes principais, correlação e conglomerados. Na avaliação dos caracteres quantitativos para todas as populações, observou-se que os descritores mais variáveis foram: número de dentes da folha inferior (DHI), comprimento da folha inferior (LHI), largura da folha superior (AHI) e número de dentes da folha superior (DHS). Entre os indivíduos de Blanca de Jericó e Piartal e dentro deles, observou-se grande segregação quanto à cor, formato da panícula e folha, cor do caule, presença de dentes e axilas nas folhas superiores e inferiores. É proposta uma chave de classificação que permite no campo poder diferenciar morfologicamente os genótipos de Piartal e Blanca de Jericó. Esta pesquisa mostra que, entre os genótipos mais cultivados no departamento de Boyacá, ainda existe uma importante diversidade fenotípica em nível inter e intraindividual, em razão do estado fenológico e das condições agroclimatológicas das diferentes regiões produtoras.

Resumo Nos últimos anos a utilização de substratos para a produção de frutos e hortícolas em estufa tem vindo a aumentar. Estes materiais apresentam várias vantagens, nomeadamente um uso mais eficiente da água e dos nutrientes e a redução da aplicação de produtos fitofarmacêuticos. No entanto, o destino destes substratos no fim da sua vida útil é um assunto controverso que necessita de aprofundamento científico. Devido ao alto teor de matéria orgânica, a incorporação de substratos orgânicos (OS) em solos agrícolas poderá representar uma mais-valia. Porém, a segurança ambiental desta prática necessita de ser avaliada devido ao risco de acumulação de contaminantes e moléculas bioativas durante os ciclos de produção. Assim, este trabalho teve como objetivo efetuar uma avaliação ecotoxicológica de um OS em fim de vida, proveniente da cultura de tomate, através da realização de ensaios padronizados. Três percentagens deste resíduo foram incorporadas num solo agrícola natural (2.5, 5 e 10%), tendo sido testados os efeitos na germinação de sementes, crescimento de plantas, reprodução de oligoquetas e atividade enzimática dos solos. Os resultados preliminares não revelaram impactos negativos preocupantes para as concentrações testadas. De futuro, são necessários estudos mais abrangentes, nomeadamente para avaliar os possíveis efeitos ecotoxicológicos em matrizes aquáticas.

Abstract In recent years the use of substrates in horticultural protected crops has been increasing. Their use presents several advantages including a more efficient use of water and nutrients and a reduction in the use of phytopharmaceutical products. However, at the end-of-life of these materials, their disposal is still a matter of continuous research and controversial discussion. Due to the high organic matter content of organic substrates (OS), the incorporation of these residues in agricultural fields could be advantageous. However, this practice requires a prior assessment of its environmental safety because of the risk of contamination and accumulation of bioactive molecules during cultivation cycles. The aim of this work was to make an ecotoxicological evaluation of one OS from soilless tomato production using standard protocols. A natural agricultural soil was amended with three increasing percentages of end-of-life OS (2.5, 5 and 10%). Effects of amended soils on seedling emergence and plant growth, earthworm reproduction rate and selected soil enzymatic activity were assessed. The preliminary results did not reveal major detrimental effects derived from the amendment of soil using end-of-life coconut substrate, at least for the percentages tested. In the future, more studies are necessary to evaluate possible impacts in freshwater resources.

ABSTRACT Wildfires are non-controlled large-scale fires of various vegetation types that have long affected the Mediterranean- climate regions, but their increased frequency and severity has led to the degradation of the ecosystems. Particularly in Chile, 147 major wildfires in 2017, were responsible of burning 546 678 ha, which included 28 729 ha of traditional small-scale non irrigated agricultural systems, highlighting the vulnerability of these agricultural soils to wildfires. Soil biological properties are more sensitive to heating than physicochemical properties. Thus, a reduction of microbial communities and associated enzyme activities generally occur in low-intensity fires (< 200 °C). Most significant changes in physicochemical properties of soil occurring in moderately intense fires (250 to 450 °C) are increases of soil pH, nutrient availability, bulk density and soil water repellency, whereas soil aggregate stability and water holding capacity generally decrease. When vegetation cover is completely destroyed by fire, emergency stabilization treatments such as mulching and seeding provide an immediate ground cover to reduce soil erosion and preserve nutrients. Therefore, it is important to define the impacts of wildfire on soil properties of agricultural lands to establish a roadmap to implement an adequate and viable restoration.

Abstrac: Polycrystalline CdTe thin films deposited in large areas present some difficulties, such as non-uniformity over the entire area. It is well known that the ratio between the thickness and grain size of CdTe thin films is approximately one. In contrast, the pin holes in CdTe should be minimized. CdS thin films as window materials must guarantee a uniform transparent film free of pinholes to avoid short-circuit in the photovoltaic device. In this work, CdTe and CdS thin films are reported in areas of 40 cm2 with optimal physical properties for potential application on solar cells. CdTe mini-modules were fabricated using CdTe and CdS layers obtained and characterized under outdoor conditions. The current-voltage measurements were performed under different load and solar irradiance conditions.

ABSTRACT Fasciolosis and paramphistomosis are a major health problem for the livestock economy worldwide. In Colombia, both distomatosis are reported in cattle, particularly in high Andean tropics, with annual economic losses close to COP 40 billion. The goal of this study was to determine the prevalence of fasciolosis and paramphistomosis in cattle from La Candelaria farm, Caucasia (Colombia), and the presence of intermediate host snails. A descriptive cross-sectional study was carried out with non-probability convenience sampling. Stool samples were collected from the animals and the diagnosis was made using the modified Dennis technique. Digenea prevalence were determined according to sex, weight, age, and race. Freshwater snails were collected in the studied area and were identified by morphology. 400 and 66 fecal samples from 178 bovines of the Zebu (Bos indicus), BON (white-eared white) breeds and the cross between them were analyzed. Fasciola hepatica and Paramphistomidae were diagnosed with a prevalence of 2,2% and 30,9%, respectively. Coinfection was diagnosed in 1,1% of the cattle. Both trematodosis were most frequent in females (p = 0,03). Freshwater molluscs Ampullariidae, Physidae and Planorbidae without digenea larval stages were identified. It was concluded that dual-purpose cattle from La Candelaria farm are exposed to F. hepatica and Paramphistomidae and are probably infected on the farm grounds. Paramphistomidae was more prevalent than F. hepatica, which agrees with other studies in herds from the Colombian high Andean tropics. Paramphistomidae was found in all age groups.

RESUMEN En muchos países la fasciolosis y la paramfistomosis representan un grave problema para la salud del sector pecuario. En Colombia hay registros de ambas distomatosis en bovinos, la mayoría en el trópico alto andino, las cuales generan pérdidas econômicas anuales cercanas a 40 000 000 000 COP. El objetivo de esta investigación fue determinar la prevalencia de fasciolosis y paramfistomosis en vacunos de la hacienda La Candelaria, Caucasia (Colombia), y la presencia de caracoles hospederos intermediarios. Para cumplirlo, se realizó un estudio descriptivo de corte transversal con muestreo no probabilístico por conveniencia. Se recolectaron heces de los animales y se hizo el diagnóstico mediante la técnica modificada de Dennis. Se establecieron las prevalencias de los digeneos de acuerdo con el sexo, peso, edad y raza. Se recolectaron caracoles dulciacuícolas en la zona estudiada y se identificaron por morfologia. Se analizaron 466 muestras fecales de 178 bovinos, de las razas Cebú (Bos indicus), BON (blanco orejinegro) y del cruce entre ellas. Se diagnosticaron F. hepatica y Paramphistomidae con prevalencias del 2,2% y 30,9%, respectivamente. En el 1,1% de los vacunos se diagnosticó coinfección. Ambas trematodosis prevalecieron en las hembras (p = 0,03). Se identificaron moluscos dulciacuícolas Ampullariidae, Physidae y Planorbidae sin estadios larvarios de digeneos. Se concluyó que los bovinos de doble propósito de la hacienda La Candelaria están expuestos a F. hepatica y Paramphistomidae, y, probablemente, se infectan en los predios de la hacienda. Paramphistomidae es más prevalente que F. hepatica, lo cual concuerda con lo descrito en algunos estudios realizados en hatos del trópico alto andino colombiano. Paramphistomidae se encontró en todos los grupos etarios.

Abstract Crisis in coronavirus times requires understanding the effects on society and establishing efficient mechanisms to prevent infections. The disinfection of personal protection equipment by UVC light remains a key opportunity area. Therefore, this letter presents the main drawbacks and challenges on the fabrication of deep ultraviolet LEDs based on III-nitrides, such as the substrate selection, dislocation reduction, the increase of external quantum efficiency, enhancement of the radiative recombination in the active region, the complications to reach high Al content in AlGaN-based UVC LED avoiding the reduction of the p-doping, replacing the p-GaN contact layer by p-AlGaN without hindering the deposition of ohmic contacts. Furthermore, the cubic phase is suggested as a promising candidate for AlGaN UVC-LEDs applications as is discussed in this work.

Abstract Introduction: Zone I extensor tendon lesion accompanies an avulsion fracture of the bone insertion. A common complication of traditional pull-out is the necrosis of the site of the button in the finger pad. Zhang described an alternative way of anchoring the cerclage to the Kirschner Wire (K-wire) to relieve the pressure in the finger pad. He describes the use of wire cerclage, for fracture reduction. The objective of this paper is to perform a comparison between wire and nylon using Zhang pull-out technique. Material and methods: We performed a cohort study comparing Nylon versus Wire in Zhang technique. Comparing cosmetic satisfaction, stiffness, residual pain, and Crawford scale. Results: When comparing the outcomes between both groups, we found no statistical difference in cosmetic satisfaction (p = 0.285), stiffness (p = 0.460), and residual pain (p =1.000), overall complications (p = 1.000), or Crawford scale (p = 1.000). We only found a significant statistical difference in pain when removing the cerclage, being greater in Group B (p = 0.008). Conclusions: We found no significant outcome difference between nylon and wire cerclage. However, at the time of removing it, patients experience less pain.

El pan de maíz amarillo y cúrcuma BM1-C mostró incrementos en la dureza en los días 2 y 3.

Abstract The objective of this research was to characterize the color, texture and sanitary quality of bread added with creole corn and turmeric. Fourteen different breads were made using six types of corn (M1, M2, M3, M4, M5 and M6). The main findings were a) The color of the corn, nixtamalized flours and doughs had a significant difference (p < 0.05) when comparing mean values of Luminosity, a* and b* parameters. Blue and reddish corn M2 (37.01), M3 (44.06) and M6 (41.07) and, yellow and yellow orange M1 (21.26), M4 (15.92) and M5 (26.01) presented the lowest values in L* and highest in b*, respectively. The smallest difference in color ∆E found in the transformation process from corn to flour and dough, was for yellow corn. b) In corn bread, significant differences in variable a* were found when comparing the same type of bread for three consecutive days, in breads BM1, BM5 and BM6, with a decrease of 7.5, 2.6 and 16.9%, with respect to the first day. c) The sanitary quality of wheat bread improves with the addition of nixtamalized corn and turmeric. The blue and red corn (M2, M3 and M6) showed the lowest number of fungal colonies in the breads with corn additives. d) The hardness of the bread made with creole corn and turmeric did not show differences during three consecutive days, benefiting its conservation. The yellow corn and turmeric bread BM1-C showed increases in the hardness on days 2 and 3, and the yellow corn and turmeric bread BM1-C showed increases in the hardness on days 2 and 3.

Abstract Introduction: Neuronal ceroid lipofuscinosis (NCLs) is an autosomal recessive neurodegenerative disorders group. We report the first case in Colombia involving a new genetically confirmed variant of a homozygous CLN6 mutation. Case report: 12-year-old male, history of blood parents and average growth until 5 years of age. At this age began focal crises, progressive regression of neurodevelopment, severe cognitive deficit, and swallowing disorder that led to gastrostomy. Clinical exome + CNVs + mitochondrial DNA genetic study identified variant NM_017882.3 (CLN6): c. 22C>T, p. (Gln8*) in homozygous, deleterious. Late-onset infantile neuronal ceroid lipofuscinosis was diagnosed. Discussion: Mutations in the CLN6 gene are associated with late-onset infantile lipofuscinosis of autosomal recessive inheritance. This variant has not been previously described in the medical literature nor is it listed in the population databases, which indicates that it is extremely rare. The treatment focuses on the control of seizures, sleep disturbances, extrapyramidal symptoms, behavioral disorders, anxiety, and psychosis. Conclusion: To date, this variant of the CLN6 gene has not been reported in the world. There are currently no etiological or disease-specific therapeutic approaches. The use of exome/whole genome sequencing can be very useful for etiological diagnosis and differential diagnosis. An early diagnosis opens the door to future care and treatment.

ABSTRACT This study aimed to determine the consumption of Planococcus citri (Risso, 1813) (Hemiptera: Pseudococcidae) nymphs and the predator:prey ratio required for high predatory efficacy and survival of Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) larvae under different densities of prey, reared in rose bushes. Consumption by first-, second-, and third-instar larvae of C. externa was assessed. The predatory efficiency and survival of the predator were calculated for larvae in the second instar under densities of 20, 40, 80, 120, and 160 nymphs of P. citri and predator:prey ratios of 1:5, 1:10, and 1:20. The assessments were performed after 24 and 48 hours of exposure between species. There was increasing consumption throughout the larval development of C. externa. The predator:prey ratios 1:5 and 1:10 were the most efficient for P. citri population reduction, but the 1:5 ratio led to lower survival of larvae than the 1:10 and 1:20 ratios. There was a positive correlation between C. externa larval density and cannibalism (ρ = 0.45) and a negative correlation between predator density and P. citri population density (ρ = -0.81). Third-instar larvae consume more P. citri nymphs than second-instar larvae. Second-instar larvae of this lacewing released at a 1:20 ratio caused total mortality of mealybug nymphs within 48 hours, regardless the density of P. citri, with high larvae survival of C. externa.

Resumen Introducción: la infección por VIH-1 induce una respuesta inflamatoria crónica exacerbada que desencadena alteraciones metabólicas y cardiovasculares; sin embargo, algunos individuos "controladores" no presentan los marcadores de progresión típicos. Dado que las pruebas que evalúan el riesgo cardiovascular carecen de precisión en pacientes con VIH-1, el estudio de parámetros inflamatorios en individuos con diferente progresión podría aportar a la definición de predictores de enfermedad cardiovascular en esta población. El objetivo es explorar diferencias y correlaciones en biomarcadores metabólicos e inflamatorios asociados con riesgo cardiovascular, comparando individuos controladores y progresores con y sin terapia antiviral. Materiales y métodos: estudio analítico transversal con 63 individuos infectados por VIH-1, clasificados en controladores y progresores (con terapia antiviral y sin esta), y controles sanos. Se midió el grosor de la íntima media carotidea (CIMT), puntajes de riesgo cardiovascular y cuantificación de perfil lipídico, glucemia en ayunas, PCR ultrasensible, dímero D, sCD14, sCD163, IL-6 e IL-18. Se realizó comparación por Anova o Kruskal-Wallis y correlación por coeficiente de Spearman. Resultados: no hubo diferencias significativas en índices de Framingham, DAD o CIMT, pero los individuos controladores presentaron menores valores de triglicéridos, comparados con los progresores. No se observaron diferencias en PCR ultrasensible, IL-6, IL-18, y sCD163, entre los grupos estudiados. La mediana del HDL fue mayor en los progresores con terapia antiviral y el CIMT en los controladores se correlacionó negativamente con sCD14. Conclusión: los individuos controladores presentan un perfil cardiovascular diferente a los individuos progresores, de acuerdo con los biomarcadores metabólicos e inmunológicos evaluados.

Abstract Introduction: HIV infection induces an exacerbated chronic inflammatory response, which triggers metabolic disorders and cardiovascular diseases; however, there are individuals, known as HIV controllers, who do not have typical progression markers. As cardiovascular risk tests are not accurate on HIV-1 infected patients, the study of metabolic and inflammatory parameters in individuals with different patterns of progression could contribute to the definition of predictors of cardiovascular disease in this population. The aim of this study was to compare HIV controllers and HIV progressors (with and without antiretroviral therapy) as well as with healthy controls in order to explore differences and correlations in metabolic and inflammatory biomarkers associated with cardiovascular risk. Materials and methods: This was a cross-sectional analytical study which included 63 individuals infected with HIV-1 classified as HIV controllers or progressors (with or without antiretroviral therapy), and a healthy control group. The following parameters were determined: carotid intima-media thickness (CIMT); cardiovascular risk scores; lipid profile, fasting glucose, high-sensitivity CRP, D-dimer, sCD14, sCD163, IL-6, and IL-18. Data were compared with Anova or Kruskal-Wallis, and correlations were evaluated by the Spearman coefficient. Results: While there were no significant differences in Framingham, DAD or CIMT values, HIV controllers exhibited lower triglycerides levels when compared with HIV progressors. No differences were observed in markers, such as high-sensitivity CRP, IL-6, IL-18, and sCD163, among the groups. The median HDL value was higher in HIV progressors on antiretroviral therapy, and CIMT in HIV controllers was negatively correlated with sCD14. Conclusion: HIV controllers have a different cardiovascular profile than HIV progressors according to their values in metabolic and immunological biomarkers.

Resumo Introdução: a infecção pelo HIV-1 induz resposta inflamatória crônica exacerbada, que desencadeia alterações metabólicas e doenças cardiovasculares; no entanto, existem indivíduos, chamados controladores, que não possuem os marcadores de progressão típicos. Tendo em vista que os testes que avaliam o risco cardiovascular carecem de precisão em pacientes com HIV-1, o estudo de parâmetros metabólicos e inflamatórios em indivíduos com diferentes padrões de progressão pode contribuir para a definição de preditores de doença cardiovascular nessa população. O objetivo é explorar diferenças e correlações em biomarcadores metabólicos e inflamatórios associados ao risco cardiovascular, comparando indivíduos controladores e progressores submetidos ou não à terapia antiviral. Materiais e métodos: Estudo analítico transversal que incluiu 63 indivíduos infectados pelo HIV-1, classificados como controladores e progressores (com e sem terapia antiviral), além de grupos controle saudáveis.

A comparação foi feita por Anova ou teste de Kruskal-Wallis e a correlação pelo coeficiente de Spearman. Resultados. Embora não tenha havido diferenças significativas nos índices de Framingham, DAD ou CIMT, os indivíduos controladores apresentaram valores de triglicerídeos mais baixos, em comparação com os progressores. Não foram observadas diferenças em marcadores como PCR ultrassensível, IL-6, IL-18 e sCD163, entre os grupos estudados. O HDL médio foi maior em indivíduos progressores em terapia antiviral, e o CIMT em indivíduos controladores foi negativamente correlacionado com o sCD14. Conclusão: os indivíduos controladores apresentam um perfil cardiovascular diferente dos indivíduos progressores, de acordo com os biomarcadores metabólicos e imunológicos avaliados.

Introduction: Postimplantation syndrome is a common disorder, produced in the immediate postoperative period after endovascular treatment of aortic disease, characterized by anorexia, thoracic or low back pain, leukocytosis, fever and elevation of C-reactive protein, occasionally associated with decreased platelet count or coagulation disorders. Aim: To assess postimplantation syndrome after endovascular aortic repair. Material and Methods: This is an observational, and descriptive study; we analyze the presence of postimplantation syndrome, in 112 successive endovascular repairs of the thoracic and abdominal aorta, over a period of 10 years (2009 to 2019), in the Hospital Dr. Eduardo Pereira in Valparaíso, Chile. Results: 112 endovascular repairs were performed, 81 cases (72.32%) corresponding to EVAR and 31 cases (27.68%) to TEVAR, incidence of post-implantation syndrome was 17.85%. Associated risk factors were age ≤ 75 years, use of polyester stent grafts, aortic covered ≥ 20 cm, surgical time ≥ 180 min, (p < 0.05). As a consequence, in this group of patients, there were associated with greater readmission rates, hospital stay rates and cardiovascular morbidity (p < 0.05). Discussion: The post-implantation syndrome leads to an increase in cardiovascuar morbidy hospital stay rates and a slower postoperative recovery, with the corresponding associated risks and costs, therefore it could be considered a complication of endovascular aortic repair. Conclusion: The inflammatory response after endovascular repair of the aorta, may be intense in some patients, the group of patients who develop this syndrome deserve close monitoring, with emphasis during the first month after surgery.

Resumen Introducción: El síndrome postimplantación es un trastorno frecuente, producido en el posoperatorio inmediato posterior al tratamiento endovascular de la enfermedad aórtica, caracterizado por la presencia de anorexia, dolor lumbar, leucocitosis, fiebre y elevación de la proteína C reactiva, asociado ocasionalmente a disminución del recuento de plaquetas o alteración de la coagulación. Objetivos: Determinar la incidencia y morbilidad asociada al síndrome postimplantación, posterior a la reparación endovascular de la patología aórtica. Material y Métodos: Estudio observacional y descriptivo, donde se analiza la presencia del síndrome post implantación en pacientes sometidos a Reparación endovascular torácica aórtica (TEVAR) y Reparación endovascular de aneurisma (EVAR), durante un período de 10 años (2009 al 2019), en el Hospital Dr. Eduardo Pereira de Valparaíso, Chile. Resultados: Se incluyeron 112 reparaciones endovasculares, 72,32% correspondientes a EVAR y 27,68% a TEVAR, incidencia del síndrome post implantación (17,85%), factores de riesgo asociados: edad ≤ 75 años, uso de endoprótesis compuesta por poliester, recubrimiento aórtico ≥ 20cm y tiempo quirúrgico >180 min; (p < 0,05), evidenciando en este grupo de pacientes mayor readmisión, estancia hospitalaria y morbilidad cardiovascular (p < 0,05). Discusión: El síndrome post implantación conduce a una recuperación posoperatoria más exigente, aumentando la morbilidad cardiovascular, readmisión y estancia hospitalaria, con los correspondientes riesgos y costos asociados, en consecuencia podría considerarse una complicación de la reparación aórtica endovascular. Conclusión: La respuesta inflamatoria puede ser intensa posterior a la reparación endovascular de la aorta, el grupo de pacientes que desarrolla este síndrome, amerita una estrecha vigilancia, con énfasis durante el primer mes de post operatorio.
