Abstract: Se llevaron a cabo dos experimentos de campo durante 2009, en la Estación Experimental de Pastos y Forrajes Sancti Spiritus, Cuba (2 1o 53' 00" latitud norte, 79° 21' 25" longitud oeste y 40 msnm), para determinar la respuesta de diferentes variedades de cereales a la biofertilización con Bradyrhizobium sp. La preparación de los inóculos y la inoculación de las semillas, se efectuaron según metodologías prestablecidas para este campo de estudio. El dise o experimental fue a través de parcelas divididas y 4 réplicas por tratamiento. Al control fertilizado se le aplicó nitrógeno (150 kg N ha-1) y se evaluaron diferentes variables agronómicas. Se aplicó análisis de varianza bifactorial; las diferencias entre medias se determinaron por la dócima de comparación de Duncan y t-student. En el experimento con Triticum se concluye que los tratamientos con mejores respuestas, fueron Triticale-inoculado y a IRM37-inoculado y que Triticum secale superó en peso seco raíz y en longitud del tallo a T. aestivum, lo que hace a esta primera especie promisoria para condiciones de sequía. En el experimento con Zea mays se concluye que aunque en peso seco aéreo los mejores tratamientos correspondieron a la fertilización química, en peso seco de la mazorca el tratamiento Canilla-inoculado, presentó valores estadísticamente iguales al de los tratamientos fertilizados, por lo que se considera positiva la respuesta de esta variedad a la biofertilización. No obstante, no se descarta la influencia de las bacterias rizosféricas autóctonas en algunas de las variables estudiadas. Two field experiments were performed in 2009 at the Experimental Station of Pastures and Forages Sancti Spiritus, Cuba (21° 53' 00" north, 79° 21' 25" west longitude and 40 m) to determine the response of different varieties of cereals to bio-fertilization with Bradyrhizobium sp. The preparations of inocula and seed inoculation were made according to preset methodologies for this field of study. The experimental design was through split-plots and 4 replicates per treatment. The fertilized control was applied with nitrogen (15 0 kg N ha-1) and agronomic variables were evaluated. We applied two-factor analysis of variance; the differences betweenmeans were determined by Duncan and t-student comparison. In the experiment with Triticum, we concluded that, the treatment with the best responses was Triticale- inoculated and IRM37-inoculated and that, Triticum secale exceeded on root dry weight and stem length compared with T. aestivum, which makes this first promising species for drought conditions. In the experim

Abstract: potato, the most important agricultural product in the colombian andean economy, has in the guatemalan potato moth (tecia solanivora povolny) its principal pest, the management of which is based on intensive use of pesticides. a potential alternative to these chemical agents is the application of plant products. under controlled conditions, the current research study tested the effect of essential oils from o. basilicum, o. majorana, m. piperita, o. vulgare, p. cablin, r. officinalis, s. officinalis and t. vulgaris, on eggs, larvae and adults of t. solanivora, as applied directly on the soil and to the tubers. the treatments had no significant effect on larval development or adult longevity. under both application modes, the patchouli and thyme oils at a 0.25% dose determined significant egg viability reductions. under increased soil moisture and oil volume application the o. basilicum, o. majorana, m. piperita and r. officinalis treatments had a significant ovicidal action too. these results reveal the potential of these essential oils for the control of t. solanivora.

Abstract: background: what is striking when studying the frequency of nosocomial infection (ni) is the variability of the study data. different frequency indicators and infection criteria are used for estimates and these make it difficult to compare works. the aim of this work is to estimate the frequency of hospital infection by using different indicators to compare the results. methods: a market study was carried out including patients admitted to four surgical units over the period of one year. the following indicators were used: proportion of patients infected, cumulative number of cases of infection and density of number of cases. the infections were detected through active search and included those acquired in intensive care units and those diagnosed after patients had been discharged from hospital. results: a total of 14.5% of the patients suffered ni and 5% of the infections were diagnosed after discharge from hospital. in 38.5% of the cases of infection a microbiological study was not requested. the general surgery unit had the highest figures for the three indicators. nevertheless, the magnitude of the differences between services was modified in line with the indicator used. conclusions: the real percentage of patients with ni is higher than the values given by the usual monitoring systems. given the trend witnessed over recent years whereby the length of hospital stays is being reduced and early discharge programmes promoted with the aim of increasing efficiency, densities for the number of cases should be estimated and these should include the ni cases diagnosed after hospital discharge in order to make valid comparisons between different institutions and periods of time.

Revista Colombiana de Psiquiatría , 2006,
Abstract: El término introspección carece de una definición universal, pero en la práctica clínica con personas con trastornos psicóticos se refiere a un estado mental que se infiere a partir de la respuesta verbal y conductual de un paciente a su enfermedad. En este artículo se revisa la evolución histórica del concepto, algunos modelos teóricos explicativos y las variables clínicas que se han relacionado con la introspección, como son la gravedad de las manifestaciones clínicas, la edad de inicio, el pronóstico, la adherencia al tratamiento, el nivel de inteligencia y las alteraciones neuropsicológicas. The term insight lacks a universal definition, but in clinical practice with patients with psychotic disorders, it refers to a mental state inferred from the verbal and behavioral response of a patient to his or her illness. This article reviews the historical development of the concept, some explanatory theoretical models, and the clinical variables which have been related to insight, such as: severity of clinical manifestations, age of onset, prognostic, adherence to treatment, level of intelligence, and neuropsychological alterations.

Revista Espa?ola de Salud Pública , 1997,
Abstract: FUNDAMENTO: Al estudiar la frecuencia de infección nosocomial (IN), llama la atención la variabilidad de los datos de los estudios. En las estimaciones se utilizan diferentes indicadores de frecuencia y criterios de infección que dificultan la comparabilidad de los trabajos. El objetivo de esta investigación fue estimar la frecuencia de infección hospitalaria, utilizando diferentes indicadores para comparar los resultados. MéTODOS: Se realizó un estudio prospectivo incluyendo los pacientes ingresados en cuatro servicios quirúrgicos durante un a o. Se utilizaron los siguientes indicadores: proporción de pacientes infectados, incidencia acumulada de infección y densidad de incidencia. Las infecciones se detectaron mediante búsqueda activa y se incluyeron las adquiridas en las UCIs y las diagnosticadas tras el alta hospitalaria. RESULTADOS: El 14,5% de los pacientes padecieron IN y el 5% de las infecciones fueron diagnosticadas tras el alta. En el 38,5% de las infecciones no se solicitó estudio microbiológico. El servicio de cirugía general fue el que presentó las cifras más elevadas en los tres indicadores, no obstante las diferencias entre servicios se modificaron en función del indicador utilizado. CONCLUSIONES: El porcentaje real de pacientes con IN es superior a los valores aportados por los sistemas habituales de vigilancia epidemiológica. Dada la tendencia observada en los últimos a os, a reducir la duración de las estancias y potenciar programas de alta precoz, con el fin de incrementar la eficiencia, deberían estimarse densidades de incidencia e incluir las IN diagnosticadas tras el alta para realizar comparaciones válidas entre diferentes centros y períodos de tiempo.
