Sistemas de Información BI: Estado Actual y Herramientas de Software Libre

Actualmente muchas empresas ya sean grandes o pequeñas, se plantean implantar en su organización un sistema de información que les ayude en la toma de decisiones. Una de las tendencias actuales es implantar un sistema de BI (Business Intelligence). Muchas organizaciones implantan este tipo de sistemas sin haber realizado un estudio previo de las necesidades y problemas de la empresa, de los beneficios que se pretenden obtener con la implantación del sistema, de la aceptación y formación de los usuarios, de las herramientas y proveedores de BI,... y así un largo etcétera de situaciones y condiciones que se deberían tener en cuenta para la implantación de esta clase de sistemas en cualquier tipo de organización, ya sea grande o pequeña.En el presente artículo se realiza una síntesis de la amalgama de información existente en los sistemas de BI, se realiza una definición aclaratoria, así como también se expone su estado actual, beneficios, factores de riesgo, pasos para conseguir una implantación exitosa y los componentes y herramientas open source de los sistemas de BI. Primero se exponen las principales herramientas open source existentes en el mercado y se profundiza más especialmente en la Suite open source de BI Pentaho.

Tests for sex-biased dispersal using bi-parentally inherited genetic markers.

Understanding why dispersal is sex-biased in many taxa is still a major concern in evolutionary ecology. Dispersal tends to be male-biased in mammals and female-biased in birds, but counter-examples exist and little is known about sex bias in other taxa. Obtaining accurate measures of dispersal in the field remains a problem. Here we describe and compare several methods for detecting sex-biased dispersal using bi-parentally inherited, codominant genetic markers. If gene flow is restricted among populations, then the genotype of an individual tells something about its origin. Provided that dispersal occurs at the juvenile stage and that sampling is carried out on adults, genotypes sampled from the dispersing sex should on average be less likely (compared to genotypes from the philopatric sex) in the population in which they were sampled. The dispersing sex should be less genetically structured and should present a larger heterozygote deficit. In this study we use computer simulations and a permutation test on four statistics to investigate the conditions under which sex-biased dispersal can be detected. Two tests emerge as fairly powerful. We present results concerning the optimal sampling strategy (varying number of samples, individuals, loci per individual and level of polymorphism) under different amounts of dispersal for each sex. These tests for biases in dispersal are also appropriate for any attribute (e.g. size, colour, status) suspected to influence the probability of dispersal.

Growth, cysts and kinetics of Borrelia garinii (Spirochaetales: Spirochaetacea) in different culture media

The aim of the present paper was to evaluate cyst formation and growth parameters of Borrelia garinii in a range of media differing in formulation and cost. A qualitative assessment of morphology and motility of B. garinii was conducted. All media were prepared aseptically and used in test tubes or Petri dishes. For each medium, the initial spirochete concentration was standardized to 10³ spirochets/mL. The following culture media were suitable to grow B. garinii: Barbour-Stoenner-Kelly, brain heart infusion and PMR. Growth was minimal at six weeks post-inoculation and maximum spirochete density was observed between 9-12 weeks. Often, the cultures developed cysts of different sizes, isolated or in groups, with a spiraled portion of variable sizes, mainly in unfavorable culture media. Brazilian Lyme disease-like illness, also known as Baggio-Yoshinari syndrome (BYS), is a new and interesting emerging tick-borne disease, caused by Borrelia burgdorferi sensu lato spirochetes, only during its cystic forms. It has been assumed that the peculiar clinical and laboratory features of BYS are consequential to the absence of a human sucker Ixodes ricinus complex tick at risk areas in Brazil, supporting the concept that the borrelia phenotypic expression pattern is modified as it is transmitted through the host.

Prevalencia y factores asociados a desnutrición entre pacientes ingresados en un hospital de media-larga estancia

OBJECTIVES To determine the prevalence of hyponutrition at admission at a mid- to long-term stay hospital. To analyze the possible factors associated to hyponutrition; the possible relationship with mortality at one month, and the treatments for hyponutrition performed. MATERIALS AND METHOD Descriptive study from the laboratory data obtained in 140 patients. For diagnosing hyponutrition, a tool based on albumin, total cholesterol, and lymphocytes levels was used. Demographical (age and gender) and clinical data (presence of pressure soars, nasogastric tube, dementia, neoplasm, previous admission to the ICU, and main diagnosis) were gathered at admission as well as the mortality at the first month. The treatments used for hyponutrition were reviewed. RESULTS patients' age was 77.1 years and 63% were females. 17.1% of the patients presented normal nutritional status, 50.7% met the criteria for mild hyponutrition, 26.4% of moderate hyponutrition, and 5.7% of severe hyponutrition. We found no association between hyponutrition and gender, nasogastric tube, soars, dementia or neoplasm, but we did so with age (P = 0.033). We found a relationship between moderate-severe hyponutrition and pressure soars (P = 0.036). We found an association between hyponutrition and mortality at one month (OR = 1.357, 95% CI 1.121 to 1.643; P = 0.02). 35.6% of the patients with moderate-severe hyponutrition received therapy for this condition (28.9% with protein supplements and 6.7% with enteral diet). CONCLUSIONS hyponutrition affects most of the patients admitted to a mid to long-term stay hospitals and is associated with higher mortality. One third of hyponutrition patients receive nutritional therapy.

Bi-ventricular axial micropump: impact on blood cell integrity.

BACKGROUND AND OBJECTIVE: Off-pump coronary artery bypass grafting has stimulated the development of micro-pumps designed to prevent the hemodynamic instability induced by heart luxation for the exposure of target vessels of the posterior wall. Impella (Aachen, Germany) developed micro-pumps with a miniaturized propeller system for both sides of the heart. The aim of this study was to analyze the impact of both pumps working together on blood cell integrity. MATERIALS AND METHODS: Both right and left-sided micro-pumps were implanted in 5 calves (body weight, 72_4 Kg) during 3 h. Blood samples for hematology and hemolysis parameters were drawn hourly. RESULTS: Both pumps performed well with a flow of 3.6 L +/- 0.3 L during the 3 h of the experiment with stable hemodynamic conditions. Mixed venous oxygen saturation was 63.4 +/- 15.2% at baseline and 63.8 +/- 16.3% at the end of the experiment (P = ns). Red cell count, LDH and free plasma hemoglobin were 6.7 +/- 2.1 x 10(12)/L, 1807 +/- 437 IU/L, and 32 +/- 9 mg/L at baseline vs. 6.1 +/- 2.1 x 10(12)/L, 1871 +/- 410 IU/L, and 52 +/- 9 mg/L at the end of the experiment (P = ns for all comparisons). Platelet count exhibited a non-significant drop (872 +/- 126 vs. 715 +/- 22 x 10(9)/L). CONCLUSIONS: This double pump system based on the Archimed screw principle is hematologically well tolerated under conditions of prolonged cardiac assist.
