Brazilian Journal of Infectious Diseases , 2007, DOI: 10.1590/S1413-86702007000400016
Abstract: chromobacterium violaceum is found in tropical and subtropical regions; it is the only chromobacterium species pathogenic for humans. due to its rare presentation, physicians often ignore the importance of this pathogen. we report a fulminant fatal case of bacteremia in a 38-year-old colombian man. the clinical manifestations were fever, thoracic pain, respiratory failure and death. his condition, from the beginning of clinical diagnosis, went into continuous deterioration, till his death, within a few days after the symptoms began. two hemocultures isolated c. violaceum. we conclude that doctors should consider this differential diagnosis in patients with systemic inflammatory response syndrome, with continuous deterioration.

Abstract: before sprouting, potato tubers pass through a period of dormancy which has an specific time for each variety. when the conditions are suitable for tuberset, stolon elongation stops and swelling starts between two last nodes of each stolon. many factors are involved in this process, but an important and coordinated action between hormones is proposed. cytokinins levels in both s. tuberosum l. varieties ica-única and tuquerre?a and s. phureja juz. et buk. var. criolla colombia were quantified during different stages of tuber development: 00 - potato tuber in stage of dormancy; 03 - tubers in break dormancy with buds between 2 to 3 mm of length; and 40 - initiation of tuber formation; swelling and duplicating initial diameter. cytokinins were extracted by thin layer chromatography, detection and quantification were carried out by cotyledon radish weight (raphanus sativus) bioessay. in the species s. tuberosum l. var. tuquerre?a (late variety) the cytokinins were absent and, in the early variety ica-única were statistically higher in the stage 03, when initiate the filled of the tuber. finally, in the early species s. phureja juz. et buk. variety criolla colombia, cytokinins were significant in the stage 00 and 03, with an evident increase in the last one. our results indicate a strong relationship between cytokinins and tuber break dormancy: cytokinins were present in early varieties and absent in the late one.

Abstract: Background: The survival of patients with multiple myeloma varies. Frequently we don’t identify the patients that could be cured with advanced therapies, nor even recognize those, in which we expect a long survival with the classic treatment measures. That’s why it is necessary the study of prognosis factors to achieve an optimum stratification and to individualize the pattern to follow. Objectives: To determine the 3 years survival of the patients with multiple mieloma and the factors that influence it. Methods: A descriptive study of a series of cases of 50 patients with multiple mieloma. The socio-demographic characteristics were studied, as well as the clinic-humoral state, type of treatment and response to it, the over life curves were calculated by the estimates of Kaplan-Meier. A uni-varied analysis was made for which the patients were stratified in groups, that were compared through the long-rank method. A trust interval of 95% was accepted. Results:The total 3 years survival was of 37%. The 58% of the cases used the combination of Melfalan with Prednisona as initial therapeutic scheme. The 47,1% of the treated patients had a positive response to the chemotherapy. There were no alarming differences in response percentage and in survival among those who received Melfalan-prednisona and those who were treated with schemes that combined both drugs. The functional capacity reduction, the association to renal insufficiency, and not having response to treatment were the factors associated to an early mortality. Conclusions: The identification by means of this study of the factors related with the illness, would allow us to stratify the sick persons and to individualize its cares to improve the survival. Fundamento: La supervivencia de los pacientes con mieloma múltiple varía. Frecuentemente no identificamos a los enfermos que pudieran curarse con el uso de terapias de avanzada, ni reconocemos a aquellos, en que esperamos una larga supervivencia con las medidas clásicas de tratamiento, por ello es necesario el estudio de factores pronósticos para lograr una estratificación óptima e individualizar la conducta a seguir. Objetivo: Determinar la supervivencia a los 3 a os de los enfermos con mieloma múltiple y los factores que influyen en ella. Métodos: Estudio descriptivo de serie de casos sobre 50 pacientes con mieloma múltiple. Se estudiaron las características socio-demográficas, estado clínico-humoral, tipo de tratamiento y respuesta a este. Las curvas de sobrevida se calcularon por el estimado de Kaplan-Meier. Se realizó un análisis univariado para el

Cabrero García,Julio;
Revista Espa?ola de Salud Pública , 2007, DOI: 10.1590/S1135-57272007000200007
Abstract: background: the measurement and meaning of disability depend on the indicators used. in this study the indicators of dependency and severe residual disability are examined on two levels: in each of the 14 selected activities of daily living (adl) and also as a summary score of the activities count. methods: the data are extracted of the disability, impairment and health survey (ine, 1999). the sample is composed of 8.779 entries corresponding to people over 65 years old with disability in some of the 14 selected adl. tables of proportions and contingency have been elaborated, statistics of association and agreement has been calculated and the dimensionality of the aggregated measures had been analyzed through the full information factor analysis. results: the main discrepancies between the indicators are concentrated on the mobility activities (kappa coefficients ranged between 0,50 to 0,75 for mobility activities and between 0,73 to 0,87 for domestic activities and self-care). severe residual disability (indicator selected by the national institute of statistics) compared to dependency more inability includes more mobility disabled people and excludes more disabled people in domestic activities and self-care. dependency more inability is the indicator with the highest validity as a summary measure of disability (two eigenvalues: 8,37 and 1,91, the first factor accounted for 56,3% of the variance, the saturations of the first factor ranged between 0,58 to 0,87). conclusions: dependency more inability is more valid than severe residual disability as main indicator of disability.

El nuevo modelo aeroportuario europeo: más competencia, mejor regulación
Julio García Cobos
Universia Business Review , 2005,
Abstract: Las líneas aéreas europeas comienzan a padecer las distorsiones provocadas por la creciente competencia entre aeropuertos. En Espa a estas distorsiones se ven acentuadas por la gestión en red, que magnifica la tradicional débil relación entre quién genera los costes aeroportuarios y quién los paga. En este contexto, proponemos un modelo de gestión más descentralizado para los aeropuertos espa oles que (i) acerque las tarifas de cada aeropuerto a sus propios costes y (ii) facilite el desarrollo de estrategias competitivas diferenciadas entre aeropuertos.
