ABSTRACT The study aims to analyze convergence and divergence between emotional intelligence and academic performance in the university context, considering that they are two similar categories, but each one with unique characteristics. The prism method has been used, based on the data of scientific documents. It was elaborated based on data collected from Scopus, PubMed and Web of Science, fundamentally considering original articles and literature reviews; for access to relevant documents, advanced search protocols were developed according to the characteristics of each database using Boolean algebra and other arguments. The analysis of 1011 scientific articles, the same ones that after applying inclusion and exclusion criteria were screened and considered for analytical reading of 78 documents. It is concluded that the relationship between the categories is convergent and divergent considering the autonomy of each one. Emotional intelligence, in its relationship with academic performance, is observed not only as a major category, but is also linked to: self-realization, self-concept, adaptability, self-management, motivation, self-esteem, emotion management, anxiety, depression, and resilience. The significant finding is based on the proposal of the concept of academic performance, which leads to the spiritual and cognitive development of the individual.

RESUMEN El estudio tiene como objetivo analizar convergencia y divergencia entre inteligencia emocional y rendimiento académico en el contexto universitario, considerando que se trata de dos categorías símiles, pero con singulares características. Se ha empleado el método prisma en base a la data de documentos científicos, fue elaborada en base a datos recopilados de Scopus, PubMed y Web of Science, considerando fundamentalmente artículos originales y revisiones de literatura; para el acceso a los documentos relevantes se elaboraron protocolos avanzados de búsqueda de acuerdo a las características de cada base de datos usando álgebra booleana y otros argumentos. El análisis de 1011 artículos científicos, los mismos que luego de aplicar criterios de inclusión y exclusión fueron cribados y considerados para la lectura analítica 78 documentos. Se concluye que la relación entre las categorías es convergente y divergente considerando la autonomía de cada una. La inteligencia emocional, en su relación con el rendimiento académico, es observada no solo como categoría mayor, sino que están vinculadas a: auto realización, autoconcepto, adaptabilidad, autogestión, motivación, autoestima, gestión de emociones, ansiedad y depresión, resiliencia. El hallazgo significativo se sustenta en la propuesta del concepto del rendimiento académico, el mismo que conduce al desarrollo espiritual y cognitivo del individuo.

ABSTRACT. This study examined biochemical changes associated with chilling injury (CI) in sweet potato roots stored at low temperatures and reconditioned at ambient temperature. Sweet potato cultivars BRS Amélia and BRS Rubissol were stored at 6 or 13°C for 4 days at ambient temperature (“ambient reconditioning”: 21 ± 2°C). CI on the outer surface of the roots occurred earlier in BRS Amélia than in BRS Rubissol. The CI index on the inner surface of the BRS Amélia was higher when it was stored at 6°C for 40 + 4 days. BRS Amélia showed higher proline content and electrolyte leakage when stored at 6°C. Ascorbate peroxidase was induced by storage at 6°C for 30 + 4 days in BRS Amélia and from 40 + 4 days in BRS Rubissol. The malondialdehyde and phenolic compounds of BRS Rubissol increased during storage at 6°C. CI in both cultivars was associated with increased peroxidase and polyphenol oxidase activities. Storage of sweet potato cultivars at 6°C for 50 + 4 days caused severe damage to the roots. Cultivars BRS Amélia and BRS Rubissol showed similar symptoms of CI and can be characterized as being sensitive to low temperatures.

Abstract: This paper analyzes the political economy factors and actors that may have influenced trade instruments in Peru during the liberalization period of 2001-2015 (which started in 1990 under Fujimori's administration). The evidence supports the hypothesis that Peruvian trade barriers liberalization in period 2000-2015 was led by the "Ministry of Economy and Finance (MEF)", accompanied by traditional and diversified exporters (that consolidated the unilateral trade liberalization) and by import substitution firms that influenced to some degree, and slowed down the rate of liberalization of unilateral trade barriers. In addition, the unilateral trade liberalization was facilitated by the weak role of the formal labor force and liberal-oriented consumer interest groups. JEL Classification: P16, F13

Resumen Este artículo analiza los factores y actores de la economía política que pueden haber influido en los instrumentos comerciales en Perú durante el período de liberalización de 2001-2015 (que comenzó en 1990 bajo la administración de Fujimori). El análisis y las evidencias respaldan la hipótesis de que la liberalización de las barreras comerciales peruanas en el período 2000-2015 fue liderada por el el Ministerio de Economía y Finanzas (MEF), acompañado por exportadores tradicionales y diversificados que consolidaron la liberalización comercial unilateral, y por empresas de sustitución de importaciones que influyeron en cierto grado y redujeron la tasa de velocidad del proceso de liberalización de las barreras comerciales unilaterales. Además, la liberalización unilateral del comercio fue facilitada por el papel débil de la fuerza laboral formal y los grupos de interés del consumidor con orientación liberal.

Resumen Ante una década de bajo nivel de productividad total factorial (PTF) en América Latina, este artículo muestra evidencias del grado de ineficiencia técnica de las empresas del sector productivo peruano. Para ello se estimaron los índices de eficiencia técnica de 116 875 empresas (83 271 formales y 33 604 informales) distribuidas en 25 regiones y diez sectores productivos (agricultura, pecuario, agropecuario, minería, pesca, manufacturas, construcción, comercio, hoteles y restaurantes, y resto de servicios no gubernamentales) obteniendo un índice promedio general de eficiencia para las regiones y sectores de Perú de 37.94 —el producto total de las empresas se multiplicaría por 2.6 sin requerir factores productivos adicionales—. Dicha cifra sugiere que intervenciones del gobierno o empresas que induzcan comportamientos técnicamente eficientes en la producción pueden contribuir a incrementar la PTF de la economía, probablemente, a menor costo y tiempo. Clasificación JEL: D24, L60.

Abstract In a decade of low TFP —factorial total productivity— in Latin America, the paper shows evidence of the low level of TFP due to the degree of technical inefficiency of companies in the Peruvian productive sector case. For this, the technical efficiency indices of 116 875 companies (83 271 formal and 33 604 informal) distributed in 25 regions and ten productive sectors (agriculture, livestock, agriculture, mining, fishing, manufacturing, construction, commerce, hotels and restaurants, and the rest are non-governmental services). The estimates yielded a general average efficiency index for the regions and sectors of Peru of 37.94 —in other words, the total product of the companies would multiply by 2.6 without requiring additional productive factors—. This figure suggests that government or company interventions that induce technically efficient behaviors in production can contribute to increasing the TFP of the economy, probably at lower cost and time. JEL Classification: D24, L60.

ABSTRACT This study aimed to evaluate the effects of mushroom meal supplementation, Pleurotus djamor var. roseus (Pd), on the diet of Nile tilapia (Oreochromis niloticus), on hematological parameters and growth performance for 60 days. Nile tilapia fingerlings (3.23 ± 0.19 g) were fed with three experimental diets based on the mushroom meal in different percentages: diet 0% control (MM0), diet 15% (MM15), diet 20% (MM20) and diet 25% (MM25). Blood samples from the fish of all treatments were collected at the start of the experiment (day 0), 30 and 60 days. The weight and size of the fish were determined every 15 days (0, 15, 30, 45 and 60 days). The results showed a significant dose-dependent increase in the levels of erythrocytes count and leukocytes count. The groups that showed significant differences in the basal value and the final control result were hematocrit, hemoglobin, and lymphocyte. An increase in lymphocytes proportion and a decrease in neutrophils were found, which was related to the immune response of fish fed the diet. The highest levels of leukocytes, lymphocytes, and low neutrophils were presented in the diet with 15 and 20% (P < 0.05). The growth (weight gain and specific growth rate) of fish fed MM15 and MM20 of Pd in the diet was higher than the control group (P > 0.05). Dietary supplementation (15 and 20%) improved hematological and defense blood cells, as well as the growth of tilapia.

Resumen En muchos tejidos vegetales, se ha utilizado el acondicionamiento a baja temperatura (LTC) para inducir respuestas adaptativas poscosecha para superar las consecuencias del daño por frío (CI). Este estudio tuvo como objetivo investigar si el LTC es eficaz para reducir la incidencia de daño por frío (CI) en cultivares de batata. Las raíces de batata BRS Cuia y BRS Rubissol se sometieron a almacenamiento en frío (6 °C o 13 °C) y LTC (10 °C durante 7 días, seguido de un segundo almacenamiento a 6 °C). El LTC aumentó la tolerancia de las raíces de la batata al IC mediante la activación del sistema antioxidante, principalmente en el cv. BRS Rubissol, que se asoció notablemente con un mayor contenido de fenoles solubles totales y prolina, así como una mayor actividad de la fenilalanina amonio liasa. Además, no se observaron lesiones externas ni internas en las raíces de LTC, manteniendo la calidad para el procesamiento, lo que indica que el LTC es eficaz para mitigar el daño por frío en los cultivares brasileños de batata.

Abstract In many plant tissues, low-temperature conditioning (LTC) has been used to induce postharvest adaptive responses to overcome chilling injury (CI) consequences. This study aimed to investigate whether LTC is effective in reducing the incidence of chilling injury (CI) in sweet potato cultivars. Sweet potato roots BRS Cuia and BRS Rubissol were submitted to cold storage (6 °C or 13 °C) and LTC (10 °C for 7 d, followed by second storage at 6 °C). LTC increased the tolerance of sweet potato roots to CI via antioxidant system activation, mainly in cv. BRS Rubissol, which was markedly associated with higher content of both total soluble phenolics and proline, as well as increased activity of phenylalanine ammonium lyase. Moreover, no either external or internal injuries were observed in the LTC roots, maintaining the quality for processing, which indicates that the LTC is effective in mitigating chilling injury in Brazilian sweet potato cultivars.

Abstract New findings of fossil remains of one of the Pilauco dung beetles, Onthophagus pilauco Tello, Verdú, Rossini and Zunino, 2021 (Coleoptera: Scarabaeidae), extinct at the base of the Younger Dryas chronozone at the end of the Pleistocene (~12,800 years before the present) in northern Patagonia, Chile, are described and illustrated. Recent analyses of material from the Pilauco site allowed us to record new fossil remains belonging to O. pilauco, including the clypeal remains with an exceptional cephalic horn, which we assign to male specimens. The new discoveries lead us to revise the previous description provided by descriptors, and to consider that the holotype of O. pilauco as a female specimen. In the light of current knowledge about the genus, the uniqueness of this phenotypic character (i.e., horn in the disc of the clypeus) within the American and Asiatic Onthophagus are discussed. From this, we suggest that the morphological novelties observed in O. pilauco correspond to unique traits among the American Onthophagus, which possibly originated from isolation during the last glaciation in northern Chilean Patagonia.

Resumen Se describen e ilustran nuevos hallazgos de restos fósiles de uno de los escarabajos estercoleros de Pilauco, Onthophagus pilauco Tello, Verdú, Rossini y Zunino, 2021 (Coleoptera: Scarabaeidae), extinto en la base de la cronozona Younger Dryas, al fin del Pleistoceno (~12.800 años antes del presente) en la Patagonia norte de Chile. Análisis recientes de material procedente del sitio Pilauco permitieron registrar nuevos restos fósiles pertenecientes a O. pilauco, incluidos restos de clípeos con un cuerno central excepcional que asignamos a especímenes machos. Los nuevos descubrimientos nos permitieron revisar la descripción propuesta anteriormente por los descriptores y atribuir el sexo hembra al holotipo de O. pilauco. A la luz de los conocimientos actuales sobre el género, se discute la singularidad de este carácter fenotípico (i.e., cuerno del disco del clípeo) dentro de los Onthophagus americanos y la posible relación con grupos de la región asiática. A partir de esto, sugerimos que las novedades morfológicas observadas en O. pilauco, corresponden a rasgos únicos entre los Onthophagus americanos, que posiblemente se originaron a partir del aislamiento durante la última glaciación en la Patagonia norte de Chile.

ABSTRACT High incidence of sprouts and loss of quality of sweet potato is one of the negative aspects that compromises the commercialization most, and the methods of sprout control are still very limited. The appearance of sprouts promotes the wilting of sweet potato roots, reducing their commercialization period. The main objectives of this study were to evaluate sprout control and physiological and biochemical changes, in addition to the impact on the quality of postharvest chips in sweet potato roots cultivar BRS Cuia treated with methyl jasmonate (MeJa) and nonanoic acid (NA). Roots were fogged with 10 μmol·L–1 MeJa or 5 μmol·L–1 NA applied at first sprout initiation and control. Physiological and biochemical alterations such as fresh weight loss assessment, sprouting incidence and sprout length, total soluble sugars, reducing sugars, nonreducing sugars, enzymatic peroxidase and polyphenol oxidase, chips quality after frying were then assessed. Besides that, to determine the influence of treatments and storage periods, multivariate analysis was also performed using the main components. The MeJa reduced the incidence of sprouting and maintained the root quality during storage at room temperature. Notably, such events led to an increased both shelf life and potential of commercialization. Moreover, MeJa-treated chips displayed lighter color appearance after frying than control and NA-treated roots. Roots fogged with NA did not suppress the growth of sprouts, which consequently triggered a higher browning intensity in fried sweet potato chips.

ABSTRACT Objective: to explore and understand patients’ needs, expectations and quality evaluation when searching for health information on the internet. Design: qualitative research with focus groups. Location: Professor Jesús Marín Primary Care Centre, Molina de Segura. Region of Murcia. Participants: three focus groups. N = 17 participants, 11 women and 6 men, aged between 24 and 55, who had recently used the internet to search for health information. Method: non-probabilistic convenience sampling of patients from a Primary Care Centre. Recording and subsequent transcription of group discussions. Text analysis by means of segmentation, categorization and speech interpretation. Researchers’ triangulation analysis. Results: when patients use the internet as a source of health-related information, accessibility, immediacy and thoroughness are highly valued, as well as the autonomy and the power it provides them in their interactions with the health system. Online searches are simple, short, very specific and, most often, limited to the results displayed on the first screen. Amongst the criteria used when selecting some web pages over the others, there their comprehensibility, design and absence of advertising are notable. In order to assess the reliability of the information, patients’ strategies rely on both contrasting different sources and their intuition. Conclusions: the internet not only fulfils the need for information, but also for emotional support, placing patients on an equal footing with professionals. The criteria and strategies used to evaluate the quality and reliability of the information found do not coincide with those defined by professionals. Overall, the experience of online searching for health information is perceived as very positive.

RESUMEN Objetivo: explorar y comprender necesidades, expectativas y valoración de la calidad desde el punto de vista de los pacientes cuando buscan información sobre salud en internet. Diseño: Investigación cualitativa con grupos focales. Emplazamiento: Centro de Salud Profesor Jesús Marín, Molina de Segura. Región de Murcia. Participantes: Tres grupos focales. Número = 17 participantes, 11 mujeres y 6 hombres, de entre 24 y 55 años, que habían usado recientemente internet para buscar información sobre salud. Método: muestreo de conveniencia con cuotas por edad y sexo. Grabación y transcripción de las discusiones grupales. Análisis de texto mediante segmentación, categorización e interpretación de los discursos. Triangulación por varios investigadores. Resultados: cuando los pacientes usan internet como fuente de información, valoran la accesibilidad, inmediatez y exhaustividad, así como la autonomía y el poder que les proporciona en su relación con el sistema sanitario. Los procesos de búsqueda son sencillos, breves, muy específicos y habitualmente se limitan a los resultados de la primera pantalla. Entre los criterios para seleccionar unas páginas web frente a otras, destacan su comprensibilidad, diseño y ausencia de publicidad. Para valorar la fiabilidad de la información, los pacientes utilizan como estrategias el contraste entre diversas fuentes y la intuición. Conclusiones: internet satisface necesidades no solo de información, sino de apoyo emocional y sitúa a los pacientes en un plano de igualdad con los profesionales. Para valorar la calidad y fiabilidad de la información encontrada, se utilizan criterios y estrategias que no coinciden con los que definen los profesionales. Globalmente, la experiencia de buscar en internet información sanitaria se percibe como muy positiva.

ABSTRACT Introduction: Although multiple clinical evidence is being generated about COVID-19, it is also critical to address the strategies and actions that people have adopted to face stressful situations during the mandatory quarantine due to the pandemic. Objective: To determine the factors associated with psychological coping to COVID-19 in the general population. Method: Analytical cross-sectional study. Participants were recruited through an online survey during the COVID-19 pandemic period. The level of passive and active coping was evaluated, using the coping scale against extreme risks. Additionally, using the mean of the passive and active coping scores, the association with sociodemographic variables, group membership, compliance with social isolation and the report of knowing someone diagnosed with COVID-19 was evaluated. Prevalence ratios (PR) were estimated using generalized linear models. Results: Of 463 participants, the majority was Peruvian (67,4 %), fully complying with social isolation measures (78,4 %). The mean active and passive coping scores were 54,1 and 30,3, respectively. 57,2 % and 54 % of the participants presented a level of active and passive coping above the mean, respectively. The factors associated with a high level of active coping were a high educational level (RP = 1,23) and complete compliance with social isolation measures (RP = 1,35). Conclusion: Having a high educational level and compliance with social isolation were positively associated with a high level of active coping.

RESUMEN Introducción: Aunque se está generando múltiple evidencia clínica sobre la COVID-19, también es crítico abordar sobre las estrategias y acciones que han adoptado las personas para enfrentar situaciones estresantes durante la cuarentena obligatoria debido a la pandemia. Objetivo: Determinar los factores asociados al afrontamiento psicológico frente a la COVID-19 en la población general. Métodos: Estudio transversal analítico. Se reclutaron los participantes a través de una encuesta en línea, durante el periodo de pandemia por la COVID-19. Se evaluó el nivel de afrontamiento pasivo y activo, utilizando la escala de afrontamiento frente a riesgos extremos. Adicionalmente, se utilizó la media de los puntajes de afrontamiento pasivo y activo, se evaluó la asociación con variables sociodemográficas, pertenencia a grupos, cumplimiento de aislamiento social y reporte de conocer alguien diagnosticado con la COVID-19. Se estimaron razones de prevalencia (RP) con el uso de modelos lineales generalizados. Resultados: De 463 participantes, la mayoría era peruano (67,4 %), cumplía totalmente las medidas de aislamiento social (78,4 %). La media de puntuación de afrontamiento activo y pasivo fue de 54,1 y 30,3, respectivamente. El 57,2 % y 54 % de los participantes presentó nivel de afrontamiento activo y pasivo superior a la media, respectivamente. Los factores asociados a alto nivel de afrontamiento activo fueron alto nivel educativo (RP = 1,23) y cumplir completamente las medidas de aislamiento social (RP = 1,35). Conclusión: Tener alto nivel educativo y el cumplimiento del aislamiento social estuvieron asociados positivamente a alto nivel de afrontamiento activo.

ABSTRACT Thraustochytrids are unicellular protists belonging to the Labyrinthulomycetes class, which are characterized by the presence of a high lipid content that could replace conventional fatty acids. They show a wide geographic distribution, however their diversity in the Antarctic Region is rather scarce. The analysis based on the complete sequence of 18S rRNA gene showed that strain 34-2 belongs to the species Thraustochytrium kinnei, with 99% identity. The total lipid profile shows a wide range of saturated fatty acids with abundance of palmitic acid (16:0), showing a range of 16.1-19.7%. On the other hand, long-chain polyunsaturated fatty acids, mainly docosahexaenoic acid and eicosapentaenoic acid are present in a range of 24-48% and 6.1-9.3%, respectively. All factors analyzed in cells (biomass, carbon consumption and lipid content) changed with variations of culture temperature (10 °C and 25 °C). The growth in glucose at a temperature of 10 °C presented the most favorable conditions to produce omega-3fatty acid. This research provides the identification and characterization of a Thraustochytrids strain, with a total lipid content that presents potential applications in the production of nutritional supplements and as well biofuels.

Este estudo comparou o desempenho em provas de fluência verbal semântica, fonêmica e de ação, em 31 pacientes com doença de Parkinson (DP), sem demência, e 61 controlos saudáveis. As funções executivas e comportamentais foram igualmente avaliadas. O tempo de evolução foi de 9,8 anos (DP = 6,13). Não foram encontradas diferenças de idade (U = 899,5, p = 0,616), género (X2= 0,00, p = 1,00) ou literacia (U = 956, p = 0,96) entre os dois grupos. Diferenças significativas foram encontradas na prova de fluência verbal de ação (U = 406,5, p < 0,01) que não se verificaram nas restantes provas. O nível educacional foi a única variável biográfica que influenciou o desempenho das tarefas, independentemente do tempo de evolução da doença. Os resultados sugerem uma correlação entre os mecanismos patológicos da DP e um déficit específico para a evocação de verbos e que a prova de fluência de ação providencia uma informação importante que não é detectada pelos restantes testes executivos.

We compared the performance of 31 non-demented Parkinson´s disease (PD) patients to 61 healthy controls in an action verbal fluency task. Semantic and phonemic fluencies, cognitive impairment and behavioural dysfunction were also assessed. The mean disease duration of PD was 9.8 years (standard deviation (SD) = 6.13). There were no age (U = 899.5, p = 0.616), gender(chi-square = 0.00, p = 1.00) or literacy (U = 956, p = 0.96) differences between the two groups. A significant difference was observed between the two groups in the action verbal fluency task (U = 406.5, p < 0.01) that was not found in the other fluency tasks. The education level was the only biographical variable that influenced the action (verb) fluency outcomes, irrespective of disease duration. Our findings suggest a correlation between the disease mechanisms in PD and a specific verb deficit, support the validity of the action (verb) fluency as an executive function measure and suggest that this task provides unique information not captured with traditional executive function tasks.

This paper is a partial account of the results obtained from a project about preferential trade arrangements (PTAs) impact on exports and imports value and the rate of economic growth in 31 Latin American and Caribbean countries during the period 1962-2005. It reports the results of PTAs' impact on trade flows of three countries Mexico, Chile and Brazil. In contrast to previous methods and results found in the literature, impact estimations are carried out by country, incorporating four types of PTAs (unilateral, generalized system of preferences, regional and multilateral arrangements) implemented in each country for the 1962-2005 period. In addition to binary variables associated with the set of PTAs, the estimations, which are based upon the gravity equation, include variables representing: i) competitive and comparative advantages (or differences in the level of economic development); i) trade barriers; iii) the relative prices of tradable goods; and iv) cultural and geographic features of trading countries.

El presente artículo describe parte de los resultados del proyecto acerca de los impactos ex post de los arreglos preferenciales comerciales (APCs) implementados por 31 países de América Latina y el Caribe en los flujos comerciales y el crecimiento económico en el periodo 1962-2005. El trabajo presenta las estimaciones de los impactos de los APCs en el valor de las exportaciones e importaciones en tres países: Brasil, Chile y México. En contraste con la literatura previa, las estimaciones se realizan por país e incorporan simultáneamente los cuatros tipos de arreglos preferenciales (unilaterales, regionales, multilaterales y los del sistema generalizado de preferencias,) que dicho país implementó (o se benefició) en el periodo considerado. En adición a las variables binarias que representan los APCs, las estimaciones, basadas en la ecuación de gravedad, incorporan variables que representan: i) las ventajas comparativas y competitivas (o diferencias en el nivel de desarrollo económico); ii) las barreras al comercio; iii) los precios relativos delos bienes transados; y iv) las características culturales y geográficas de los países que comercian.

Objective: An open, randomized clinical trial was performed in order to determine the efficacy of local application of granulate Sugar (GS) vs. 10% yodopovidone (YP) solution in wound infection prevention in patients with secondary peritonitis due to acute appendicitis (SPAA). Methods:: Between 1991 to 1996 a total of 135 patients with SPAA were surgically treated in the Hospital Nacional Cayetano Heredia. Patients were assigned randomly to receive GS o YP in the surgical wound. Results: Groups were comparable in the baseline for gender, age, disease severity, time duration of surgical procedures. The rate of wound infection up to Post-operatory day 5 was 39.39 % (26 / 66) for YP group vs. 28.99% (20/69) (p = 0.20) for CS group. Wound delayed closure (WDC) after Post-operatory day 5 was performed in 89 patients. Incidence of Wound infection in patients after WDC was 40% (16/40) for YP group vs 20.41 % (10/49) for GS Group (p =0.04, OR: 2.6 CI95%= 0.92 a 7.42). Wound infection rate at the end of follow up was 63.64% (42/66) for YP group vs 43.48 % (30 / 69 ) for GS (p= 0.02, OR: 2.28 , IC95% = 1.08 - 4.83). ( Rev Med Hered 2003; 14:74-80 ).

Objetivo: Se realizó un estudio clínico, de asignación aleatoria, abierto (no ciego) para comparar la eficacia, en la disminución del Riesgo de Infección, de la aplicación de Azúcar de caña granulado (ACG) vs solución de yodopovidona al 10% (YP), de Herida operatoria en pacientes con Peritonitis Generalizada por Apendicitis Aguda (PGAA). Métodos: Entre 1991 y 1996 se incluyeron a estudio 135 sujetos con diagnóstico de PGAA, intervenidos quirúrgicamente en el Hospital Nacional Cayetano Heredia. Los pacientes fueron asignados aleatoriamente a recibir (ACG) o (YP) en la Herida Operatoria. Resultados: Ambos grupos fueron estadísticamente comparables en sus características basales como género, edad, promedio de volumen de exudado purulento libre en cavidad peritoneal aspirado, volumen de solución salina al 0.9% usado para el lavado de cavidad peritoneal y en el tiempo operatorio. La frecuencia de infección de herida al 5to día del Post-operatorio para el grupo YP fue de 39.39 % (26 / 66) y el grupo ACG de 28.99% (20/69) (p = 0.20). Se realizó Cierre primario retardo luego del 5to día de Post-operatorio en 89 pacientes, en estos se observó infección de herida en 40% (16/40) para el Grupo YP vs 20.41 % (10/49) para el Grupo ACG (p =0.04, OR: 2.6 IC95%= 0.92 a 7.42). El total de infección de Herida al final del seguimiento fue de 63.64% (42/66) para el grupo YP vs 43.48 % (30 / 69 pacientes ) para el Grupo ACG. (p= 0.02, OR: 2.28 , IC95% = 1.08 - 4.83). ( Rev Med Hered 2003; 14:74-80 ).
