Resumen Introducción. La producción de alimentos regionales con identidad local y cultural se ha convertido en un negocio atractivo para los pequeños productores, porque permite que se comercialicen resaltando los ingredientes locales y el procesamiento tradicional que refleja el know-how de cada región. El queso de pasta hilada es un ejemplo. Objetivo. Identificar las características sensoriales y el nivel de agrado de quesos de pasta hilada costarricense (Palmito). Materiales y métodos. El proyecto se desarrolló en las instalaciones de la Universidad de Costa Rica, durante el 2015. Se utilizaron diecinueve muestras de queso Palmito costarricense. Catorce de ellas fueron fabricadas por productores artesanales y cinco por industriales. Se siguió la metodología de análisis descriptivo cuantitativo genérico (QDA) con diez jueces capacitados, que definieron veintiún atributos. Se realizó un análisis de clústeres (AHC) y análisis de componentes principales (PCA) para relacionar las muestras con sus atributos. La prueba de aceptación se realizó con cien consumidores. Se aplicaron técnicas de AHC del consumidor y mapeo preferencial externo para correlacionar los resultados de agrado con los obtenidos en el QDA. Resultados. Se obtuvieron diferencias significativas (p<0,05) entre muestras en el QDA para todos los atributos. Las muestras se agruparon en tres grupos de acuerdo con la similitud de su atributo. El PCA mostró un grupo, principalmente con quesos tradicionales, agrupados por sabor ácido, salado, firmeza, humedad y apariencia hilada, mientras que otro grupo, correspondiente a quesos almacenados en refrigeración, pasteurizados y sin pasteurizar, tuvieron una mayor intensidad de color amarillo, textura grasienta, suavidad y menor apariencia hilada. Un último grupo, compuesto por una muestra, presentó sabor a lechuga. Conclusión. Se concluyó, a través del mapeo preferencial externo, que a los consumidores les gusta la mayoría de los quesos Palmito industriales, pero prefieren los tradicionales con características como apariencia hilada y sabor cremoso.

Abstract Introduction. The production of regional food with local and cultural identity has become an attractive business for small-scale producers because it allows them to market their products highlighting local ingredients and traditional processing that reflects the know-how of each region. One example is Pasta filata cheese. Objective. To identify sensory characteristics and level of liking for Costa Rican Pasta filata cheeses (Palmito cheese). Materials and methods. The project was carried out at the facilities of the University of Costa Rica, during 2015. Nineteen samples of Costa Rican Palmito cheese were used, with fourteen of them being produced by artisanal producers and five by industrial producers. The methodology of Generic Quantitative Descriptive Analysis (QDA) was followed, with ten trained judges defining twenty-one attributes. Agglomerative Hierarchical Clustering (AHC) and Principal Component Analysis (PCA) were conducted to relate the samples to their attributes. Acceptance testing was performed with one hundred consumers. Consumer AHC and external preference mapping were applied to correlate the results of the liking with those of the QDA. Results. Significant differences (p<0,05) among samples were obtained in the QDA for all attributes. The samples were grouped into three clusters based on similarity attributes. The PCA showed one group, primarily consisting of traditional cheeses, clustered by attributes such as acid and salty flavor, firmness, moisture, and stringy appearance. Another group, corresponding to refrigerated, pasteurized, and unpasteurized cheeses, had a higher intensity of yellow color, greasy texture, softness, and less stringy appearance. A final group, composed of one sample, had a lettuce flavor. Conclusion. Through the external preference mapping, it was concluded that consumers like the majority of industrial Palmito cheeses, but they prefer traditional ones with characteristics such as stringy and creamy flavor.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

Abstract: Polymethylmethacrylate (PMMA) is a well known material in dental prostheses and implants. It has been proven to have a desirable property for dental applications, because of its good aesthetics, biocompatibility, decreased water absorption, transparent and light-weight, and highly durable, among others. The major problem is the microbial adhesion to PMMA when it is in the oral cavity. Despite all these beneficial properties, it is still considered to have certain disadvantages that or drawbacks which could be substantially improved with the addition of different nanoparticles (NPs). In this systematic review, we studied extensively the use of various types of metal NPs (silver - Ag, and copper - Cu) as well as magnesium phosphate - MgP, and compared its effects with the PMMA alone. The research articles showed either a positive or an improved antimicrobial effects compared to conventional PMMA by experimental and non-clinical studies.

Resumen: El polimetilmetacrilato (PMMA) es uno de los materiales más conocidos en la fabricación de prótesis e implantes dentales, con propiedades óptimas para su aplicación odontológica debido a las características favorecedoras como son: buena estética, biocompatibilidad, bajo nivel de absorción en agua, ser transparente, ligero y fuerte. Pese a todas estas beneficiosas propiedades, se considera que posee desventajas que se verían mejoradas con la adición de nanopartículas de distintos materiales. En la presente revisión sistemática, se identifica como problema principal la adhesión microbiana al PMMA cuando este se encuentra en cavidad oral. El objetivo se centró en comparar el uso de las nanopartículas (NPs) de diferentes metales (plata - Ag y cobre - Cu) así como de fosfato de magnesio - MgP, con el PMMA. Dentro de los principales resultados, la mayoría de los artículos mostraron efectos antimicrobianos positivos o mejorados en comparación con el PMMA convencional.

Resumen La gran diversidad de la quinua permite variaciones en el desempeño fisiológico, productivo y composicional. El objetivo de este estudio fue evaluar seis cultivares de quinua a través de las respuestas fisiológicas y nutricionales de sus semillas. Se identificaron diferentes dinámicas en la altura de las plantas y en el número de hojas que se ajustaron a un modelo sigmoidal con R2 mayor a 0,97 y 0,77, respectivamente. La concentración de clorofila varió a través de las fases fenológicas, al igual que el rendimiento cuántico máximo del fotosistema II. Se encontraron diferencias en los granos de quinua entre las coordenadas colorimétricas del CIEL*a*b* y el contenido de proteínas, carbohidratos y grasas. En este sentido, se determinó que los cultivares de quinua manifiestan diferentes comportamientos biológicos asociados a su carácter genético. Además, se reconoció una relación entre cultivares y la composición de semillas. Estos resultados permitirán a los investigadores estudiar la diferencia significativa entre la precocidad expresada por los cultivares Puno, Nariño y Titicaca y aquellos con un ciclo fenológico más largo como el cultivar Soracá.

Abstract The great diversity of quinoa allows variations in physiological, production, and compositional performance. This study aimed to evaluate six quinoa cultivars through the physiological and nutritional responses of their seeds. Different dynamics were identified in the plant height, and the number of leaves was adjusted to sigmoidal models with R2 greater than 0.97 and 0.77, respectively. The chlorophyll concentration varied through the phenological phases, as did the maximum quantum yield of photosystem II. Differences in the quinoa grains were found between CIEL*a*b* colorimetric coordinates and protein, carbohydrate, and fat contents. In this sense, quinoa cultivars manifest different biological behaviors associated with their genetic nature. Besides, a relationship between cultivars and seed composition was recognized. These results will allow researchers to study other significant differences between the precocity expressed by the Puno, Nariño, and Titicaca cultivars and those with a longer phenological cycle such as the Soracá cultivar.

Abstract Background Regional anesthesia has been increasingly used. Despite its low number of complications, they are associated with relevant morbidity. This study aims to evaluate the incidence of complications after neuraxial block and peripheral nerve block. Methods A retrospective cohort study was conducted, and data related to patients submitted to neuraxial block and peripheral nerve block at a tertiary university hospital from January 1, 2011 to December 31, 2017 were analyzed. Results From 10,838 patients referred to Acute Pain Unit, 1093(10.1%) had side effects or complications: 1039 (11.4%) submitted to neuraxial block and 54 (5.2%) to peripheral nerve block. The most common side effects after neuraxial block were sensory (48.5%) or motor deficits (11.8%), nausea or vomiting (17.5%) and pruritus (8.0%); The most common complications: 3 (0.03%) subcutaneous cell tissue hematoma, 3 (0.03%) epidural abscesses and 1 (0.01%) arachnoiditis. 204 of these patients presented sensory or motor deficits at hospital discharge and needed follow-up. Permanent peripheral nerve injury after neuraxial block had an incidence of 7.7:10,000 (0.08%). The most common side effects after peripheral nerve block were sensory deficits (52%) and 21 patients maintained follow-up due to symptoms persistence after hospital discharge. Conclusion Although we found similar incidences of side effects or even lower than those described, major complications after neuraxial block had a higher incidence, particularly epidural abscesses. Despite this, other serious complications, such as spinal hematoma and permanent peripheral nerve injury, are still rare.

Resumen Objetivo: Determinar la circulación de poliovirus en tres municipios considerados como punto transitorio de migrantes en Colombia. Material y método: Se colectaron muestras de aguas residuales (n=36) de municipios fronterizos, seleccionados por mayor tránsito de migrantes regulares como irregulares, en el periodo comprendido entre el 2017-2019. Las muestras fueron concentradas y cultivadas siguiendo el algoritmo de vigilancia ambiental para la circulación de poliovirus de la Organización Mundial de la Salud (OMS). La identificación molecular se realizo mediante reacción en cadena de la polimerasa empleando cebadores específicos de grupo, de serotipo y de cepa vacunal sabin. Resultados y Discusión: Se detectó la presencia de Enterovirus no polio (EVNP) en las muestras ambientales obtenidas y no se hallo circulación de poliovirus deriva dos de la vacuna ni de poliovirus salvaje en los tres municipos evaluados; sin embargo en dos estudios previos publicados por Gonzalez y col con una metodologia similar en el año 2005 y 2015 evaluando las aguas residuales de la ciudad de Armenia-Quindio; se logró identificar la presencia de virus derivado de vacuna, con resultados negativos para la identificación de poliovirus salvaje. Conclusiones: Los hallazgos indican que el sistema de monitoreo de aguas residuales con el fin de determinar la presencia de virus es una herramienta util para realizar vigilancia ambiental.

Abstract Objective: To determine the circulation of poliovirus in three municipalities considered as transitory points for migrants in Colombia. Material and Method: Wastewater samples (n = 36) were collected from border municipalities, selected for greater transit of regular and irregular migrants, in the period between 2017-2019. The samples were concentrated and cultured following the World Health Organization (WHO) environmental surveillance algorithm for poliovirus circulation. Molecular identification was performed by polymerase chain reaction using group-specific, serotype and sabin vaccine strain primers. Results: The presence of non-polio Enterovirus (NPV) was detected in the environmental samples obtained and no circulation of poliovirus derived from the vaccine or wild poliovirus was found in the three evaluated municipalities; However, in two previous studies published by Gonzales et al with a similar methodology in 2005 and 2015 evaluating the wastewater of the city of Armenia-Quindío; It was possible to identify the presence of virus derived from vaccine, with negative results for the identification of wild poliovirus. Conclusions: The findings indicate that the wastewater monitoring system in order to determine the presence of viruses is a useful tool to carry out environmental surveillance.

Resumen Los Objetivos de Desarrollo Sostenible ODS comprometen a 193 países en el mejoramiento de indicadores ambientales, sociales y económicas a través de su desempeño en 169 metas para el 2030 con el fin de lograr el cumplimiento del acuerdo de Paris. Sin embargo, las dinámicas de desarrollo en relación con los ODS cambian a través del tiempo y con ello, los países no identifican las fortalezas y debilidades en las que se visibiliza la realidad de su territorio. Además, los indicadores se han abordado de manera individual debido a que su multidimensionalidad generan resultados divergentes. En este sentido, el objetivo de esta revisión es analizar el estado de evolución de los ODS en América y particularmente en Colombia. Para analizar la dinámica de los ODS en 32 países de América, sistematizamos los datos de los indicadores oficiales de 2010 a 2019 y los indicadores de la División de Estadística de las Naciones Unidas (DENU) teniendo en cuenta variables como el Producto Interno Bruto PIB per cápita, las emisiones de gases de efecto invernadero y las energías renovables. Como se esperaba, los países presentaron diferente fortaleza en el desarrollo de los indicadores relacionados con sinergias y antagonismos de los ODS. En este sentido, se logró encontrar amplia distribución en el avance de los ODS, encontrando a nueve países que lograron cumplir por lo menos en un objetivo la totalidad de las metas, lo que permite visibilizar que cada una de las naciones, ha tomado iniciativas gubernamentales para lograr el desarrollo y la calidad de vida de sus pobladores.

Abstract The Sustainable Development Goals (SDG), commit 193 countries to improving environmental, social and economic indicators through their performance on 169 targets by 2030 in order to achieve compliance with the Paris Agreement. However, development dynamics in relation to the SDGs change over time and with this, countries do not identify the strengths and weaknesses in which the reality of their territory is visible, in addition to the indicators they have been addressed individually because its multidimensionality generates divergent results. In this sense, the objective of this review is to analyze the state of evolution of the SDGs in America and particularly in Colombia. To analyze the SDG dynamics in 32 countries of America, we systematize the official indicator data from 2010 to 2019 and United Nations Statistics Division (UNSD) indicators taking into account variables such as per capita gross domestic product, greenhouse gas emissions and renewable energies. As expected, the countries presented different strength in the development the indicators related to synergies and antagonisms of the SDGs. Also, it was possible to find a wide distribution in the advancement of SDGs, finding nine countries that managed to meet at least one of the goals, which allows make visible that each of the nations has taken government initiatives to achieve development and quality of life its inhabitants.

Abstract Dam B1 was approximately 85 m high and 700 m long along the crown when it suddenly failed in 25th of January, after 41 years of operations and deposition of tailings at the Paraopeba mining complex (Côrrego de Feijão), in Minas Gerais, Brazil. More than 250 people died and vast economic, social and environmental damages resulted from the collapse. Given the need to geotechnically characterise the tailings within the dam for a credible computational model of the failure, an extensive sampling and laboratory testing campaign took place. The geotechnical laboratory of the Civil Engineering Department at the Faculty of Engineering of the University of Porto (Portugal) was invited by CIMNE, under a contract with VALE, with MPF agreement, to conduct this program. This paper will present a description of the sampling campaigns in the remaining post-mortem dam/reservoir tailings were the failure instability mechanics developed and the experimental program undertaken to test the tailings in advanced laboratory tests. The results that embrace evaluations of the physical, hydraulic and mechanical properties, deduced from integral samples selectively collected and prepared as described, which allowed to define the geotechnical parameters necessary for the referred analyses are here resumed.

Abstract Introduction: colorectal cancer (CRC) has an important impact on morbidity and mortality globally, and nitroxidative stress, inflammation, and nutritional status are linked with its progression. Aim: to analyze the association of inflammatory, anthropometric, functional, and oxidative markers with tumor stage in newly-diagnosed CRC patients at a public reference center in Maceió, Alagoas, Brazil. Methods: patient-generated subjective global assessment was applied, and weight, height, arm circumference, triceps skinfold (TSF), arm muscle circumference, and handgrip strength were obtained. A fasting blood sample was collected, centrifuged, and the serum was stored at -80 °C until the analysis. Malonaldehyde levels were quantified by HPLC (high-performance liquid chromatography) and cytokines, namely tumor necrosis factor-alpha, and interleukins IL-6, IL-8, and IL-17 were analyzed by ELISA. Patients were grouped according to cancer stage into group 1 (stage 0-III) and group 2 (stage IV). A binary logistic regression analysis was performed, adjusted for sex and age, to assess the relationships between the variables studied and cancer stage. Significance was considered when p < 0.05. Results: twenty-eight CRC patients were included, twenty (71.4 %) from group 1 and eight (28.6 %) from group 2. The binary logistic regression revealed that lower TSF adequacy (OR = 0.929; CI 95 % = 0.870-0.993; p = 0.029) and higher IL-6 levels (OR = 1.001; CI 95 % = 1.000-1.002; p = 0.012) increased the chance of patients having tumor stage IV. Conclusion: These data support that IL-6 and TSF may help in cancer stage assessment in clinical practice. Modulation of inflammation by IL-6 levels may be a target in CRC treatment.

Resumen Introducción: el cáncer colorrectal (CCR) tiene un impacto importante en la morbilidad y mortalidad a nivel mundial, y el estrés nitroxidativo, la inflamación y el estado nutricional están relacionados con su progresión. Objetivos: analizar la asociación de los marcadores inflamatorios, antropométricos, funcionales y oxidativos con el estadio tumoral de pacientes con CCR recién diagnosticados en un centro público de referencia de Maceió, Alagoas, Brasil. Métodos: se aplicó la valoración global subjetiva generada por el paciente y se obtuvieron el peso, la altura, la circunferencia del brazo, el pliegue cutáneo del tríceps (PCT), la circunferencia del músculo del brazo y la fuerza de prensión. Se tomó una muestra de sangre en ayunas, se centrifugó y el suero se almacenó a -80 °C hasta el momento del análisis. Los niveles de malonaldehído se cuantificaron por CLAR (cromatografía líquida de alta resolución) y las citocinas, representadas por el factor de necrosis tumoral alfa y las interleucinas IL-6, IL-8 e IL-17, se analizaron mediante ELISA. Los pacientes se agruparon según el estadio del cáncer en grupo 1 (estadio 0-III) y grupo 2 (estadio IV). Se realizó una regresión logística binaria, ajustada por sexo y edad, para evaluar las relaciones entre las variables estudiadas y el estadio del cáncer. Se consideró la significancia cuando p < 0,05. Resultados: se incluyeron veintiocho pacientes con CCR, de los cuales veinte (71,4 %) eran del grupo 1 y ocho (28,6 %) del grupo 2. La regresión logística binaria reveló que una menor adecuación de PCT (OR = 0,929; IC 95 % = 0,870-0,993; p = 0,029) y los niveles más altos de IL-6 (OR = 1,001; IC 95 % = 1,000-1,002; p = 0,012) aumentaban la probabilidad de que los pacientes tuvieran un tumor en estadio IV. Conclusiones: estos datos señalan que la IL-6 y el PCT pueden ayudar en la evaluación del estadio del cáncer en la práctica clínica. La modulación de la inflamación por los niveles de IL-6 podría ser una diana en el tratamiento del CCR.

Resumo As vantagens da telemedicina incluem observação, diagnóstico, tratamento e monitorização do utente à distância. Devido à pandemia por COVID-19, o recurso à teleconsulta aumentou, pretendendo evitar deslocações desnecessárias e contágios. Com este trabalho, procurou-se avaliar a evidência existente sobre teleconsulta em outcomes de saúde na população seguida nos Cuidados de Saúde Primários e/ou que os procura para resolução de doença aguda, através de uma pesquisa sistemática nas bases de dados de medicina baseada na evidência de estudos que analisem a teleconsulta nos Cuidados de Saúde Primários. Foram incluídas duas revisões sistemáticas. A primeira demonstrou que as consultas telefónicas são uma opção apropriada em determinadas situações, reduzindo a carga de trabalho na prática clínica. A segunda revelou que as intervenções de telemedicina são eficazes e custo-efetivas. Tendo em consideração o limitado número de estudos sobre o tema e o facto de apresentarem limitações, atribuiu-se uma força de recomendação SORT B.

Abstract The rewards of telemedicine include the possibility of patient observation, diagnosis, treatment and monitoring at a distance. Due to the COVID-19 pandemic, the use of teleconsultation increased, aiming at avoiding unnecessary travelling and disease spreading. This work aimed at evaluating the existing evidence regarding teleconsultation and its health outcomes in the Primary Care population, including in the acute setting, through a systematic research in evidence-based medicine databases of studies evaluating teleconsultation in Primary Care. Two systematic reviews were included. The first one showed that telephonic consultations are an appropriate alternative in some settings, reducing workload in clinical practice. The second one revealed that telemedicine is both an effective and cost-effective intervention. Considering the limited number of studies on this subject and their limitations, a B-level SORT strength of recommendation was attributed.

RESUMEN Uno de los temas que poco se ha profundizado es la evaluación del clima organizacional en empresas del sector agropecuario bajo análisis de estadísticas multivariadas, es así que el propósito del presente estudio es construir y validar un instrumento para medir el clima organizacional de las empresas tecnificadas de ganadería de leche, bajo un enfoque mixto, con un alcance exploratorio de tipo tecnológico psicométrico, desarrollando un análisis de variables categóricas. La muestra de estudio fueron 45 fincas, las cuales, se analizaron bajo 9 dimensiones, soportadas en 97 ítems, bajo la escala Likert, donde el alfa de Cronbach obtenido fue de 0.9044395, lo que evidencia que los datos son confiables y que existe consistencia interna entre las preguntas del cuestionario. El análisis de resultados, se hizo mediante técnicas multivariadas de correspondencia simple para cada una de las dimensiones establecidas, permitiendo analizar la problemática desde un enfoque psicosocial. La dimensión de mayor preocupación fue la de Contexto social, que evidenció problemas relacionados con la escasa oportunidad de interacción social, pocos espacios de recreación y esparcimiento familiar; la dimensión mejor evaluada fue la de liderazgo y participación, demostrando una muy buena relación con el jefe. En general, se pude decir que el mayor porcentaje de agrupamiento de las respuestas está alrededor de la opción siempre, correspondiente a la calificación ideal para cada ítem, representado en el 57,32%, lo que indica un comportamiento cercano a lo óptimo, en determinadas variables analizadas.

ABSTRACT One of the topics that have not been studied in depth is the evaluation of the organizational climate in companies of the agricultural sector under multivariate statistical analysis. Thus, the purpose of this study is to construct and validate an instrument to measure the organizational climate of technified dairy cattle raising companies, under a mixed approach, with an exploratory scope of psychometric technological type, developing an analysis of categorical variables. The study sample consisted of 45 farms, which were analyzed under 9 dimensions supported by 97 items under the Likert scale, where the Cronbach's alpha obtained was 0.9044395, which shows that the data are reliable and that there is internal consistency among the questions of the questionnaire. The analysis of the results was carried out using multivariate techniques of simple correspondence for each of the established dimensions, allowing the analysis of the problem from a psychosocial approach. The dimension of greatest concern was the social context. This showed problems related to the scarce opportunity for social interaction, few spaces for recreation, and family recreation; the best-evaluated dimension was that of Leadership and participation, showing a very good relationship with the boss. In general, it can be said that the highest percentage of the grouping of responses is around option always, that correspond to the ideal qualification for each item, represented in 57.32%, which indicates a behavior close to the ideal in certain variables analyzed.

RESUMO: O objetivo desta pesquisa foi estimar a prevalência da leishmaniose visceral canina (LVC) e identificar as diferenças nos fatores relacionados à sua ocorrência nas zonas urbana e rural do município de Santa Luzia, localizado no semiárido paraibano. Nos anos de 2015 e 2016, coletaram-se 779 amostras de sangue de cães. A prevalência foi determinada através de três técnicas sorológicas, Kit ELISA-S7®, teste rápido DPP® e Kit EIE-LVC®, considerando positivas as amostras que reagiram em, pelo menos, dois ensaios. Os fatores relacionados foram determinados por meio das análises estatísticas uni e multivariada das respostas dos tutores ao questionário epidemiológico. A prevalência de anticorpos anti-Leishmania infantum encontrada no município estudado foi de 15,00% (117/779), sendo maior na zona urbana (15,20%) do que na rural (13,60%). O bairro que apresentou maior prevalência foi o Frei Damião com 26,40% (33/125), sendo considerado um hotspot (OR 1,245; p=0,007). Outros fatores relacionados encontrados foram a criação semidomiciliar (OR 1,798; p=0,025), na zorna urbana, e cão de caça (OR 18,505; p=0,016), contato com bovinos (OR 17,298; p=0,022) e ambiente onde o cão é criado (OR 4,802; p=0,024), na zona rural. Verifica-se a elevada prevalência da leishmaniose visceral canina e a sua ampla distribuição no município de Santa Luzia. Diferenças epidemiológicas entre as zonas urbana e rural puderam ser observadas, demonstrando a necessidade de medidas de controle mais adequadas para cada localidade e comprovando o processo de urbanização.

ABSTRACT: The objective of this study was to estimate the prevalence of canine visceral leishmaniasis (CVL) and to identify the differences in associated factors to its occurrence in urban area and countrysides in the municipality of Santa Luzia located in the semi-arid region of Paraíba. In the years 2015 and 2016, 779 blood samples from dogs were collected. The prevalence was determined by three serological techniques, ELISA-S7® Kit, DPP® Rapid Test and EIE-LVC® Kit, considering positive the samples that reacted in at least two assays. Associated factors were determined by univariate and multivariate analyzes of the guardians’ responses to the epidemiological questionnaire. The prevalence of anti-Leishmania infantum antibodies in the studied municipality was 15.00% (117/779), being higher in the urban area (15.20%) than in the countryside (13.60%). The neighborhood with the highest prevalence was Frei Damião with 26.40% (33/125), being considered a hotspot (OR 1.245, p=0.007). Other associated factors were the semi-domiciliary breeding (OR 1.798, p=0.025), in the urban area, and hunting dog (OR 18.505, p=0.016), contact with cattle (OR 17.298, p=0.022) and environment where the dog is raised (OR 4.802, p=0.024) in the countryside. In the municipality of Santa Luzia, the prevalence of canine visceral leishmaniasis is high and the disease is widely distributed. Epidemiological differences between urban area and the countryside could be observed demonstrating the need for more adequate control measures for each locality and proving the urbanization process.

Abstract The improvement of superior wheat cultivars depends on the identification of promising segregating populations to derive superior lines. A lattice model (8×8) involving 56 F2 populations and eight parents was conducted in the 2020 cropping season, and grain yield per plant was evaluated for every F2 population, with further analysis of the population potential by Jinks and Pooni method via REML/BLUP. A total of 5,410 F2 plants were evaluated in this study. The results showed that the use of genetic variance associated with the individual genotypic value (BLUP) was superior compared with the use of variance and traditional phenotypic values. The F2 populations, CD 1303/BRS 254, CD 1303/Tbio Duque, CD 1303/Tbio Ponteiro, BRS 264/Tbio Aton, Tbio Ponteiro/Tbio Aton, and Tbio Sossego/CD 1303 had the highest likelihood of deriving superior lines.
