Resumo Barragens são umas das principais ameaças para peixes potamódromos Neotropicais, causando bloqueios de rotas migratórias e perdas de áreas de reprodução em um número crescente de sistemas de drenagem. Neste cenário, dados atuais defendem que a manutenção de tributários de fluxo livre em bacias hidrográficas fragmentadas seria uma importante estratégia na conservação de peixes migradores, tanto em situações de panmixia quanto em cenários com diferentes estoques coexistindo, tal como já relatado para Prochilodus lineatus. Este estudo analisou locos microssatélites e haplótipos mitocondriais em amostras de P. lineatus obtidas em diferentes anos ao longo da bacia do rio das Cinzas, no reservatório de Capivara (maior reservatório na calha principal do rio Paranapanema, alto rio Paraná) e no rio Tibagi, todos conectados por trechos livres, visando investigar as contribuições da bacia do rio das Cinzas na dinâmica populacional de peixes migradores na região do reservatório de Capivara. Ambos os marcadores detectaram altos níveis de diversidade genética e indicaram diferentes estoques de P. lineatus ao longo da bacia do rio das Cinzas, sugerindo alguma estruturação genética temporal, bem como a mistura destes estoques na amostra do reservatório de Capivara e de outros pontos, corroborando as relações de estoques neste reservatório e seus tributários.

Abstract Dams are one of the main threats to Neotropical potamodromous fish, causing blockages of migratory routes and loss of breeding areas in an increasing number of drainage systems. In this scenario, current data argue that the maintenance of free-flowing tributaries along fragmented watersheds would be an important strategy to the migratory fish conservation, both in panmixia situations and in scenarios with different coexisting stocks, as already reported for Prochilodus lineatus. This study analyzed microsatellite loci and mitochondrial haplotypes in samples of P. lineatus obtained in different years along the Cinzas River basin, as well as in the Capivara Reservoir (largest Reservoir in the Paranapanema main channel, upper Paraná River) and in the Tibagi River, all connected by free stretches, aiming to investigate the contributions of the Cinzas River basin to the population dynamics of migratory fish in the Capivara reservoir region. Both markers detected high genetic diversity levels and indicated different genetic stocks of P. lineatus along the Cinzas River basin, suggesting some temporal genetic structuring, as well as the mixture of these stocks in the sample from the Capivara reservoir and from other points, corroborating the relationships among stocks in this reservoir and its tributaries. systems scenario freeflowing flowing conservation P largest channel stretches region structuring points

RESUMEN A nivel mundial, la varroasis continúa siendo el principal problema sanitario en los sistemas de producción apícola, causando grandes pérdidas económicas; actualmente en la península de Yucatán se ha reportado la presencia de Varroa, sin embargo, se desconoce cuál de las 4 especies parasitan a las abejas Apis mellifera en el Estado de Campeche. El objetivo de esta investigación fue identificar morfométricamente la especie predominante de Varroa (Parasitiformes: Varroidae) en colonias de abejas en Hopelchén, Campeche; para ello de 5 apiarios se evaluaron 61 colmenas, de cada una se colectaron de 200 a 300 abejas; para el análisis morfométrico, 244 ácaros fueron colocados en ácido láctico al 50% durante 2 horas a 100ºC, y posteriormente se midieron los segmentos en un micrómetro ocular. Los resultados indicaron que el 100% de los ácaros evaluados pertenecen a la especie de Varroa destructor, los conglomerados K medias indicaron diferencias intraespecíficas (P< 0.05) observándose 5 morfotipos de V. destructor, las variables que presentaron mayor variabilidad fueron ancho del escudo anal (P=0.001) y ancho del escudo genital (P=0.001). Se concluye que a pesar de que el 100% de los ácaros pertenecieron a V. destructor estos presentaron diferencias morfométricas intraespecíficas.

ABSTRACT Worldwide, varroasis continues to be the main sanitary problem in beekeeping production systems, causing great economic losses; currently in the Yucatan Peninsula the presence of Varroa has been reported, however, it is unknown which of the 4 species parasitize Apis mellifera bees in Campeche State. The aim of this research was to identify morphometrically the predominant species of Varroa (Parasitiformes: Varroidae) in bee colonies in Hopelchén, Campeche; for this purpose, 61 hives were evaluated from 5 apiaries, 200 to 300 bees were collected from each one; for the morphometric analysis, 244 mites were placed in 50% lactic acid for 2 hours at 100ºC, and then the segments were measured in an ocular micrometer. The results indicated that 100% of the mites evaluated belonged to the Varroa destructor species, the mean K clusters indicated intraspecific differences (P< 0.05), observing 5 morphotypes of V. destructor, the variables that presented greater variability were width of the anal shield (P=0.001) and width of the genital shield (P=0.001). It is concluded that although 100% of the mites belonged to V. destructor, they showed intraspecific morphometric differences.

OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.

Abstract: En | Text: En | PDF: En

Catalysis is an important tool in obtaining a range of derivative products from renewable sources, such as ethanol. Solid-state dealumination using ammonium hexafluorosilicate on the BEA zeolite under the treatment at temperature of 190 °C, 70 mol% dealumination in the presence of humidity and washing with buffer solution at 25 °C generated larger pores. The absence of washing procedure for the same sample resulted in pore blockage. Ethanol dehydration reactions showed conversion of 72% (64% ethylene and 8% diethyl ether) for this sample at 300 °C and high weight hourly space velocity (WHSV, 3247 h-1), whereas, at the same temperature but at a low WHSV (57 h-1), the conversion was 88% (49% ethylene and 39% diethyl ether). Dealuminated BEA zeolite presented better diffusion conditions, higher hydrophobicity and generated larger pores. Impregnation with H3PW12O40, H4SiW12O40 and Nb2O5 explained the selectivity, showing that Lewis acid sites from Nb2O5 favored the diethyl ether production.

Abstract Objective: To evaluate prevalence, clinical manifestations, laboratory abnormalities and treatment in a multicenter cohort study including 847 childhood-onset systemic lupus erythematosus (cSLE) patients with and without diffuse alveolar hemorrhage (DAH), as well as concomitant parameters of severity. Methods: DAH was defined as the presence of at least three respiratory symptoms/signs associated with diffuse interstitial/alveolar infiltrates on chest x-ray or high-resolution computer tomography and sudden drop in hemoglobin levels. Statistical analysis was performed using Bonferroni correction (p < 0.0022). Results: DAH was observed in 19/847 (2.2%) cSLE patients. Cough/dyspnea/tachycardia/hypoxemia occurred in all cSLE patients with DAH. Concomitant parameters of severity observed were: mechanical ventilation in 14/19 (74%), hemoptysis 12/19 (63%), macrophage activation syndrome 2/19 (10%) and death 9/19 (47%). Further analysis of cSLE patients at DAH diagnosis compared to 76 cSLE control patients without DAH with same disease duration [3 (1–151) vs. 4 (1–151) months, p = 0.335], showed higher frequencies of constitutional involvement (74% vs. 10%, p < 0.0001), serositis (63% vs. 6%, p < 0.0001) and sepsis (53% vs. 9%, p < 0.0001) in the DAH group. The median of disease activity score(SLEDAI-2 K) was significantly higher in cSLE patients with DAH [18 (5–40) vs. 6 (0–44), p < 0.0001]. The frequencies of thrombocytopenia (53% vs. 12%, p < 0.0001), intravenous methylprednisolone (95% vs. 16%, p < 0.0001) and intravenous cyclophosphamide (47% vs. 8%, p < 0.0001) were also significantly higher in DAH patients. Conclusions: This was the first study to demonstrate that DAH, although not a disease activity score descriptor, occurred in the context of significant moderate/severe cSLE flare. Importantly, we identified that this condition was associated with serious disease flare complicated by sepsis with high mortality rate.

Abstract We present the characterization of the main properties of a sample of 98 AGN host galaxies, both type-II and type-I, in comparison with those of ≈2700 non-active galaxies observed by the MaNGA survey. We found that AGN hosts are morphologically early-type or early-spirals. AGN hosts are, on average, more massive, more compact, more centrally peaked and more pressure-supported systems. They are located in the intermediate/transition region between star-forming and non-starforming galaxies (i.e., the so-called green valley). We consider that they are in the process of halting/quenching the star formation. The analysis of the radial distributions of different properties shows that the quenching happens from inside-out involving both a decrease of the efficiency of the star formation and a deficit of molecular gas. The data-products of the current analysis are distributed as a Value Added Catalog within the SDSS-DR1411.

Resumen Presentamos la caracterización de las propiedades de 98 galaxias que albergan AGN, tanto de Tipo-I como de Tipo-II, en comparación con ≈2700 galaxias no activas extraídas del mapeado MaNGA. Las galaxias con AGN son de tipo temprano y espirales tempranas. Las galaxias con AGN son, en promedio, más masivas, compactas y concentradas en las partes centrales que las no activas, además de estar más soportadas por presión. Las galaxias con AGN se encuentran en la zona de transición entra las galaxias con formación estelar y las que no forman estrellas (valle verde), estando en el proceso de inhibir/detener su formación estelar. Las distribuciones radiales de diferentes propiedades muestran que esta inhibición ocurre desde dentro hacia fuera, debido a un decremento tanto de la eficiencia de la formación estelar como del gas molecular. Los productos de este análisis están disponibles como un Catálogo de Valor Añadido incluido en el SDSS-DR1411.

RESUMO Objetivou-se utilizar a metodologia de resposta simultânea aplicada a um delineamento experimental para determinar a melhor combinação de tempo e das condições de armazenamento para a conservação de grãos de café. Frutos de Coffea arabica L. foram colhidos no estádio de maturação cereja, processados por via úmida ou por via seca e secados até atingir 11% de teor de água. Parte dos grãos foi beneficiada e parte não foi beneficiada antes de ser armazenada em duas condições de ambiente: em ar refrigerado a 10 ºC e umidade relativa de 50% e em 25 ºC sem controle da umidade relativa do ar. Nos períodos de 3, 6 e 12 meses, foram retiradas amostras para avaliação da qualidade. Os dados foram submetidos à técnica de otimização de resposta simultânea para cada processamento e beneficiamento separadamente, em delineamento inteiramente casualizado e esquema fatorial 2 x 3 (duas condições de armazenamento e três períodos de armazenamento). Conclui-se que a utilização da metodologia de resposta simultânea é viável para ser aplicada para determinação das condições ideais de armazenamento em condição refrigerada.

ABSTRACT The objective of the study was to use methodology of simultaneous optimization of multiple responses applied to an experimental design to determine the best combination of storage period and conditions for preservation of coffee beans. Coffea arabica L. fruits were harvested in the ripe stage of maturation, processed using wet and dry methods, and dried to 11% (wet basis) moisture content. Part of the beans was hulled, while the other part was hulled only after the beans were stored under two different environmental conditions: cooled air at 10 ºC with 50% relative humidity; and at 25 ºC without controlling the relative humidity. Samples were taken at 3, 6, and 12 months intervals in order to evaluate quality. The data were submitted to the simultaneous optimization of responses for each processing and hulling condition separately, in a completely randomized design and 2 x 3 factorial scheme (two storage conditions and three storage periods). In conclusion, the use of the simultaneous optimization of responses is viable to be applied for determining the ideal storage conditions in a refrigerated condition.

O objetivo do presente estudo foi avaliar a contagem de células somáticas, a prevalência e a etiologia da mastite bubalina nas estações seca e chuvosa em um rebanho de bubalinos do município de Analândia, estado de São Paulo, Brasil. Adicionalmente, verificou-se o perfil de sensibilidade antimicrobiana dos micro-organismos isolados nas amostras de leite das búfalas. Foram avaliadas 1.042 amostras de leite de búfalas da raça Murrah pertencentes a uma propriedade rural localizada no município de Analândia-SP, obtidas no período de maio de 2011 e novembro de 2012. Após o exame físico da glândula mamária, foram realizados o teste da caneca de fundo escuro e o California Mastits Test (CMT); em seguida, foram colhidas, de forma asséptica, amostras de 50mL de leite de cada quarto mamário, para a contagem de células somáticas (CCS) em aparelho automático e exame microbiológico. Também, foi avaliado o perfil de sensibilidade antimicrobiana a ampicilina, cefoperazona, ceftiofur, enrofloxacina, gentamicina, neomicina, oxacilina, penicilina e sulfametoxazol/trimetoprim, pelo método de difusão em disco. A temperatura média e o índice pluviométrico mensais foram obtidos no Centro Integrado de Informações Agrometeorológicas (CIIAGRO) do Instituto Agronômico de Campinas (IAC). Notou-se que as amostras de leite com resultado positivo no exame microbiológico apresentaram CCS média de 137.720 células/mL, no período seco, e 190.309 células/mL, no período chuvoso. Embora tenha se constatado maior índice de isolamentos de micro-organismos nas amostras de leite obtidas no período chuvoso (69/600) do que no período seco (50/442), a frequência de isolamentos não foi influenciada significativamente pela estação do ano. Os principais gêneros de micro-organismos isolados durante o período seco foram Staphylococcus coagulase negativa (38,4%), Streptococcus agalactiae (28,8%) e Bacillus spp. (7,56%), e no período chuvoso Corynebacterium sp. (23,5%), Streptococcusspp. (32,3%) e Streptococcus agalactiae (9,24%). Verificou-se resistência a três ou mais antimicrobianos em 30,1% dos micro-organismos isolados.

The aim of this study was to evaluate somatic cell count (SCC), prevalence and etiology of mastitis in a dairy buffalo herd from Analândia, São Paulo State, Brazil, in the dry and rainy seasons. Additionally, antimicrobial susceptibility profile of microorganisms isolated from milk samples was also evaluated. 1,042 milk samples from female Murrah buffaloes in a dairy farm located in Analândia, São Paulo State, Brazil, collected between May 2011 and November 2012 were analyzed. After the mammary gland physical examination, strip cup test and California Mastitis Test (CMT) were performed. Afterwards, 50mL of milk samples from each mammary quarter were collected aseptically for SCC in automatic equipment and microbiological examination. The antimicrobial sensitivity profile to ampicillin, cefoperazone, ceftiofur, enrofloxacin, gentamicin, neomycin, oxacillin, penicillin, and sulfamethoxazole/trimethoprim was evaluated by disk diffusion method. The monthly average temperature and pluviometric index were obtained from "Centro Integrado de Informações Agrometeorológicas" (CIIAGRO) of "Instituto Agronômico de Campinas" (IAC). Milk samples with positive results in the microbiological test showed average SCC of 137,720 cells/mL in the dry period and 190,309 cells/mL in the rainy period. Although a higher number of isolated microorganisms was observed in buffalo milk samples during the rainy period (69/600) compared to the dry period (50/442), the season had no significant effect on the frequency of isolation of microorganisms. The main genera of microorganisms isolated were coagulase-negative Staphylococcus (38.4%), Streptococcus agalactiae(28.8%), and Bacillus spp. (7.56%) during the dry season and Corynebacterium sp. (23.5%), Streptococcus spp. (32.3%), and Streptococcus agalactiae (9.24%) during the rainy period. Multidrug resistance was observed in 30.1% of the isolated microorganisms.

Neste trabalho objetivou-se verificar a influência do uso de tela de polipropileno com 80% de retenção luminosa nas respostas fisiológicas de ovinos da raça Santa Inês submetidos a pastejo; para isto, um experimento foi montado em Petrolina, PE, no período de junho a novembro de 2010 e adotados dois tratamentos (com sombreamento e sem sombreamento) com 20 animais em cada um. Aferiu-se a temperatura retal, a temperatura da superfície cutânea e a frequência respiratória, às 7 h e 15 h, duas vezes por semana. Foram medidos dados meteorológicos visando à determinação do índice de temperatura de globo negro e umidade, a cada 2 h, por 24 h durante todo o experimento. Verificou-se, após análise dos dados, que os ovinos do tratamento com sombreamento sofreram redução em todas as variáveis fisiológicas avaliadas, quando comparados com os do tratamento sem sombreamento. A utilização do sombreamento é justificada, em especial no período da tarde visto que todas as variáveis sofrem maior alteração.

In order to verify the influence of the use of polypropylene fabric with light retention 80 in physiological responses of Santa Inês sheep under grazing, an experiment was conducted in Petrolina, PE, between June to November of 2010. Two treatments (with and without shading) were adopted with 20 animals in each. Rectal temperature, skin surface temperature and respiratory rate at 7:00 am and 3:00 pm twice a week were measured. Meteorological data were recorded for the determinations of the temperature index of black globe and humidity, every 2:00 hours during 24 hours, throughout the experiment. It was verified after analysis of the data that sheep under shade treatment had suffered reductions in all physiological variables evaluated, when compared with the treatment without shade. The use of shading is justified, in particular in the afternoon, since all variables showed greater change.

Com o objetivo de observar os efeitos do sombreamento propiciado pela tela de polipropileno sobre o comportamento de ovinos da raça Santa Inês em diferentes épocas do ano, montou-se um experimento em Petrolina, PE, no período de junho a novembro de 2010. Utilizaram-se 40 animais distribuídos em igual quantidade em dois tratamentos (Sombreado e Não sombreado) com oferta de pastagem (Tiffton 85) irrigada. Foram feitas aferições dos dados meteorológicos em todas as épocas, com a montagem de termômetros de globo negro e psicrômetros nas duas áreas e de uma mini-estação meteorológica na área sombreada. Nessas épocas foram realizados ensaios de comportamento tendo-se feito observações visuais pelo método da varredura instantânea em intervalos de 10 min no período diurno, verificando-se o percentual de animais quanto à alimentação, ruminação e ócio, a partir da metodologia proposta por Johnson & Combs (1991) adaptada para o tempo de 12h. O sombreamento não influenciou no número de animais em referência às atividades avaliadas nos diferentes tratamentos. A procura por sombra foi intensa nos períodos mais quentes do dia para a atividade de ócio.

With the goal of observing the effects of shade provided by polypropylene screen on the behaviour of Santa Inês sheep, in different times of year, an experiment was set up in Petrolina, PE, in the period from June to November 2010. Forty animals divided into equal quantity in two treatments (shaded and non-shaded) were used with supply of irrigated pastures (Tiffton 85). Measurements of meteorological data were made at all times, with the assembly of black globe thermometers and psychrometers in the two areas, and a mini-weather station, at the shaded area. Under these conditions a trials was carried out on behavior of animals, being made visual observations by the method of instantaneous scan at intervals of 10 min during the daytime period, checking the percentage of animals under food, rumination and leisure using the methodology proposed by Johnson & Combs (1991), adapted for a period of 12 h. The shading did not influence the number of animals under the activities evaluated in different treatments. The search for shade was intense in the hottest periods of the day for leisure activity.

Introduction: The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for evidence-based strategic policies. Objective: To determine the characteristics of papers published in nutrition journals. Method: Descriptive study design. We reviewed 330 original papers published between January-June 2007. From: American Journal of Clinical Nutrition (AJCN), Journal of Nutrition, European Journal Nutrition, European Journal of Clinical Nutrition and Public Health Nutrition. We classified them according to the subjects studied; risk factors, study design and country of origin. Results: Almost half the papers studied healthy people (53.3%). The most frequent illness was obesity (13.9%). Food consumption is the most frequent risk factor (63.3%). Social factors appear exclusively only in 3.6% of the papers. Clinical trials were the most common analytical design (31.8%), mainly in the AJCN (45.6%). Cross-sectional studies were the most frequent type of observational design (37.9%). Ten countries produced over half of the papers (51.3%). The US publishes the highest number of papers (20.6%), whilst developing countries make only scarce contributions to scientific literature on nutrition. Conclusions: Most of the papers had inferential power. They generally studied both healthy and sick subjects, coinciding with the aims of international scientific policies. However, the topics covered reflect a clear bias, prioritizing problems pertaining to developed countries. Social determinants of health should also be considered, along with behavioral and biological risk factors.

Introducción: El crecimiento de la producción científica nutricional indica relevancia para la comunidad científica. Las características y calidad de los estudios determinan si sus lectores pueden obtener conclusiones válidas, y su utilidad en la orientación de estrategias políticas basadas en la evidencia. Objetivo: Determinar las características de las publicaciones en revistas de nutrición. Método: Estudio descriptivo. Se revisaron 330 artículos originales publicados entre enero-junio de 2007 en las revistas: American-Journal of Clinical-Nutrition (AJCN), Journal of Nutrition, European-Journal Nutrition, European-Journal of Clinical-Nutrition y Public-Health-Nutrition. Los artículos se clasificaron según los temas estudiados, factores de riesgo, diseño del estudio y país de origen. Resultados: Las personas saludables representan la mitad (53,3%) de la población estudiada. La obesidad fue la enfermedad más frecuente (13,9%). El consumo de alimentos fue el factor de riesgo más frecuente (63,3%). Un 3,6% de artículos consideraron factores sociales. Los ensayos-clínicos fueron los estudios analíticos más comunes (31,8%), principalmente en AJCN (45,6%). Los estudios-transversales más frecuentes fueron observacionales (37,9%). Diez países producen más de la mitad de los artículos (51,3%). Los EEUU publican el mayor número de artículos (20,6%); siendo escasa la contribución de los países en desarrollo. Conclusiones: La mayoría de los artículos presentan poder inferencial. La población estudiada se distribuye entre sana y enferma, coincidiendo con los objetivos de las políticas científicas internacionales. Sin embargo, los temas tratados reflejan un sesgo, dando prioridad a los problemas relativos a países desarrollados. Deberían considerarse determinantes sociales de la salud, junto con factores de riesgo de comportamiento y biológicos.

Objective Determining the relationship between mammography neoplasm reports and histopathological diagnosis of neoplasms. Methods A descriptive cross-sectional study was carried out. Patients were included who were attending the state cancerology centre (Centro Estatal de Cancerología) in Colima, Mexico. Inclusion parameters were: females having mammography and BIRADS score of 1 or over; females having biopsy and histopathology diagnosis; females of all ages, all clinic stages having a complete clinic record. Frequency, percentages, means and standard deviations were applied for descriptive statistics. Student's t-test, the Chi square test, OR and 95 %CI were applied for inferential statistics. Differences were considered to be significant when p<0.05. Results No relationship between a BIRADS score classified as being benign (BIRADS I-II-III) or malign (BIRADS IV-V) was found with histopathological results (benign or malign) (p=0.0666). Significant relationships by category were found in a separate analysis: category IV (OR=0.024, 95 %CI=0.005-0.11, p=0.0007) and category V (OR=40.5, 95 %CI=9.03-181.3, p=0.0002). Conclusions I, III and V BIRADS scores had a relationship with histopathological diagnosis, while category II and IV BIRADS scores had no relationship. However, only categories 4 and5 were statistically significant.

Objetivo Determinar la relación entre los hallazgos de tumores mediante mamografía y el diagnóstico histopatológico de los mismos. Métodos Se realizó un estudio transversal descriptivo. Participaron pacientes del Centro Estatal de Cancerología de la ciudad de Colima, México. Los criterios de inclusión fueron: mujeres con mamografía y calificación BIRADS; mujeres con biopsia y diagnóstico histopatológico; mujeres de todas las edades, todos los estadios clínicos y con expediente clínico completo. Para la estadística descriptiva se utilizaron las frecuencias, porcentajes, promedios y desviación estándar. Para la estadística inferencial se utilizaron las pruebas de t de Student, de chi cuadrada y el cálculo del OR e IC (95 %). Las diferencias se consideran significativas cuando p<0,05. Resultados Al relacionar las categorías del BIRADS, dependiendo de la probabilidad de benignidad (BIRADS I-II-III) o malignidad (BIRADS IV-V) con los resultados histopatológicos (benigno o maligno), no se encontró relación (p=0,0666). En un análisis individual por categoría, las relaciones significativas fueron: categoría IV (OR=0,024, IC=0,005-0,11, p=0,0007) y categoría V (OR=40,5, IC=9,03-181,3, p=0,0002). Conclusiones La clasificación BIRADS I, III y V tuvo relación con el diagnóstico histopatológico, mientras que en el II y IV no hubo esta relación. Sin embargo, los únicos resultados estadísticamente significativos se obtuvieron en las categorías IV y V.

Abstract The introduction of Odocoileus virginianus texanus in areas outside of its natural distribution has caused crossbreeding among subspecies that could affect native germplasm. To manage these populations correctly, genetic variability among O. v. texanus, O. v. veraecrusis, O. v. carminis and O. v. miquihuanensis was determined in northeastern México using the Base Escision Sequence Scanning technique (BESS-T) to analyze the mitochondrial region (D-loop) in 106 DNA samples. Twenty-four haplotypes were found: 17 in O. v. texanus (four shared with the other subspecies), three haplotypes in O. v. veraecrusis, two in O. v. carminis and two in O. v. miquihuanensis. O. v. texanus inter- and intra-population variability was evaluated according to its geographic origin. It was concluded that the genetic diversity in the State of Tamaulipas (0.89) was higher than in the States of Coahuila (0.82) and Nuevo León (0.56).

Resumen La introducción de Odocoileus virginianus texanus en áreas fuera de su distribución, ha causado el entrecruzamiento de subespecies que podría afectar el germoplasma nativo. Para manejar adecuadamente estas poblaciones se determinó la variabilidad genética entre O. v. texanus, O. v. veraecrucis, O. v. carminis y O. v. miquihuanensis en el noreste mexicano, utilizando la técnica Base Escision Sequence Scanning (BESS-T) para analizar la región mitocondrial (D-loop) en 106 muestras de ADN. Se encontraron 24 haplotipos: 17 en O. v. texanus (cuatro compartidos con las demás subespecies), tres haplotipos en O. v. veraecrucis, dos en O. v. carminis y dos en O. v. miquihuanensis. En O. v. texanus se evaluó la variabilidad intere intra-poblacional según su origen geográfico. Se concluye que la diversidad genética en el Estado de Tamaulipas fue mayor (0.89) que en los Estados de Coahuila (0.82) y Nuevo León (0.56).
