We assess the epidemiology and risk factors for mortality of bloodstream infection (BSI) in patients with acute leukemia (AL).
Prospectively collected data of a cohort study from July 2004 to ...February 2016. Multivariate analyses were performed.
589 episodes of BSI were documented in 357 AL patients, 55% caused by gram-positive bacteria (coagulase-negative staphylococci 35.7%, Enterococcus spp 10.8%) and 43.5% by gram-negative bacteria (E. coli 21%, PA 12%). We identified 110 (18.7%) multidrug-resistant (MDR) microorganisms, especially MDR-Pseudomonas aeruginosa (7%) and extended-spectrum beta-lactamase producing Enterobacteriaceae (7%). The 30-day mortality was 14.8%. Age (OR 3.1; 95% CI 1.7-5.7); chronic lung disease (4.8; 1.1-21.8); fatal prognosis according to McCabe index (13.9; 6.4-30.3); shock (3.8; 1.9-7.7); pulmonary infection (3.6; 1.3-9.9); and MDR-PA infections with inappropriate treatment (12.8; 4.1-40.5) were related to mortality. MDR-PA BSI was associated to prior antipseudomonal cephalosporin use (9.31; 4.38-19.79); current use of betalactams (2.01; 1.01-4.3); shock (2.63; 1.03-6.7) and pulmonary source of infection (9.6; 3.4-27.21).
MDR organisms were commonly isolated in BSI in AL. Inappropriate empiric antibiotic treatment for MDR-PA is the primary factor related to mortality that can be changed. New treatment strategies to improve the coverage of MDR-PA BSI should be considered in those patients with risk factors for this infection.
In this paper, we present a review of some recent results concerning the thermal corrections to the Casimir energy of massless scalar, electromagnetic, and massless spinor fields in the Einstein and ...closed Friedmann universes with a cosmic string. In the case of a massless scalar field, it is shown that the Casimir energy can be written as a simple sum of two terms; the first one corresponds to the Casimir energy for the massless scalar field in the Einstein and Friedmann universes without a cosmic string, whereas the second one is simply the Casimir energy of the electromagnetic field in these backgrounds, multiplied by a parameter λ=(1/α)−1, where α is a constant that codifies the presence of the cosmic string, and is related to its linear mass density, μ, by the expression α=1−Gμ. The Casimir free energy and the internal energy at a temperature different from zero, as well as the Casimir entropy, are given by similar sums. In the cases of the electromagnetic and massless spinor fields, the Casimir energy, free energy, internal energy, and Casimir entropy are also given by the sum of two terms, similarly to the previous cases, but now with both terms related to the same field. Using the results obtained concerning the mentioned thermodynamic quantities, their behavior at high and low temperatures limits are studied. All these results are particularized to the scenario in which the cosmic string is absent. Some discussions concerning the validity of the Nernst heat theorem are included as well.
Here, we report a patient with ring chromosome 6 r(6), associated with anterior segment dysgenesis (ASD) and other anomalies. The phenotype was due to a 1880 kb microdeletion at 6p25.3 identified by ...whole‐genome array analysis, and was mainly attributable to a FOXC1 haploinsufficiency. Currently 37 patients with r(6) have been reported. We found that facial dysmorphism, ASD, heart anomalies, brain anomalies, and hearing loss are constant features only in severe cases of r(6), mainly related to hemizygosity of FOXC1. Thus, overlaps with other FOXC1 related phenotypes, such as the 6p25 deletion syndrome, Axenfeld‐Rieger syndrome type 3, and ASD type 3. Contrarily, those patients whose r(6) does not disrupt FOXC1, have mild or moderate phenotypes and do not exhibit ASD.
The boom of the evaluation processes of the national educative systems decisively influences the educative agents. Therefore some ground theoretical bases linked to the educative policies have been ...established and presented the results of the research where, through the Delphi method was asked the opinion of a group of experts on the impact of the institutional evaluation policies in the role played by the families. To accomplish that, two rounds of questions were performed. The first, where through an Open Question Opinion Interview, was asked to define the role family and the students play facing the evaluation policies. The second opinion was gathered using an Open Semi-structured Interview to detect the level of agreement or disagreement on a series of categorized phrases after an analysis of contents.
Among the most outstanding results, a participative perspective and of information receptiveness prevailed in relation to the contents of the primary phrases. While the idea of family control as far as their capacity of exigency registered a much lower intensity, letting us perceive that the level of exigency and supervision are in part restricted. It is also possible to emphasize that the greater degree of concurrence among the experts is shown in items that potency a perspective of the families as informants and as privileged receptors of the evaluation results. While there is less degree of agreement as far as to attribute families with more actives roles on putting in practice the evaluation practices.
The alternatives that the teaching staff and the families have proposed to improve the quality of the Educative Participation are analyzed in the present investigation. The sample is formed by a ...group of 8 educative experts, a pilot sample of 35 professors and a definitive sample of 695 professors and 1305 parents of 223 educative centers pertaining to 30 municipalities of Tenerife. The design used in this investigation has been qualitative. The answers to the open questions, on alternatives which they think could improve the quality of the participation were submitted under a process of categorization by means of the technique of the content analysis. For both sectors the alternatives to improve the quality of the participation, goes mainly by educative-pedagogic changes. The most relevant alternative is going to differ depending on one sector or the other, although in both the alternative reflects a deficiency in the other sector. For the teaching staff, the improvement alternative covers the lack of family formation while for the parents it fills the vacuity of information that they have coming from the teaching staff. On the other hand, the educative experts insist more on causing the importance that the society should give to the education demanding a high quality public service through the creation of joint platforms for a democratic management. In addition the also demand that the articles should be less academism and that the educative goals should be more adequate to the social reality lived by the students.
Based on the body’s energy field, the inventors of Power Balance® have created a hologram that theoretically runs through frequencies that are in our natural environment. Its creators say that people ...may experience improve balance, strength, flexibility, endurance, concentration, coordination and recovery time, among others. The purpose of this research is to evaluate the effect of Power Balance® hologram on balance, flexibility, strength and speed-coordination in university students. A sample of 105 young volunteers’ physical education students (age 20.91 ± 3.36 years, mass 69.69 ± 11.35 kg, height 171.70 ± 8.07 cm) was used. A between-group experimental design with double-blind control group was used to evaluate the possible effects of the Power Balance ® on the dynamic balance, flexibility, abdominal strength, endurance and speed-coordination measured with the Dynamic Balance Test, Sit and Reach, Sit-ups in 30 seconds and Race 10 x 5 m, respectively. A t of Student for independent and dependent samples was used to assess the potential effects between-group and intra-group, respectively. Power Balance®’s hologram produces no significant effects on the balance, flexibility, strength and speed-coordination among university students
En la presente investigación, se analizan las alternativas que tanto el profesorado como las familias plantean para mejorar la calidad de la Participación Educativa. La muestra la forman un grupo de ...8 expertos educativos, una muestra piloto de 35 profesores y una muestra definitiva de 695 profesores y 1305 padres y madres de 223 centros educativos pertenecientes a 30 municipios de Tenerife. El diseño empleado en esta investigación ha sido cualitativo. Las respuestas a la pregunta, de modalidad abierta, sobre cuáles son las alternativas que creen pudieran mejorar la calidad de la participación se sometieron a un proceso de categorización mediante la técnica del análisis de contenido. Para ambos sectores, las alternativas para mejorar la calidad de la participación pasa, principalmente, por cambios educativos-pedagógicos. La alternativa más importante va a diferir según se trate de un sector o de otro, aunque en ambos dicha alternativa refleja una carencia en el otro sector. Para el profesorado, la alternativa de mejora pasa por cubrir la carencia de formación de las familias mientras que para los padres llenar el vacío de información que tienen por parte del profesorado. Por su parte, los expertos educativos insisten más en propiciar la importancia que la sociedad debe darle a la educación con la defensa de un servicio público de calidad a través de la creación de plataformas conjuntas para la gestión democrática. Además demandan que los currículos sean menos academicistas y que los objetivos educativos se adecuen más a la realidad social que vive el alumnado.
El auge de los procesos de evaluación de los sistemas educativos nacionales influye de manera decisiva en los agentes educativos. Por ello se establecen algunas bases teóricas vinculadas a las ...políticas educativas y se presentan los resultados de una investigación en donde se pide, a través del método Delphi, la opinión de un grupo de expertos sobre el impacto de las políticas de evaluación institucional en el papel de las familias. Para ello se hicieron dos rondas de preguntas. Una primera donde a través de una Entrevista de Opinión con Preguntas de Modalidad Abierta, se les pedía que definieran el papel de las familias y el alumnado ante las políticas de evaluación. Y una segunda opinión utilizando la Entrevista Abierta Semiestructurada para detectar el grado de acuerdo o desacuerdo sobre una serie de frases categorizadas tras un análisis de contenido.Entre los resultados más destacados y en relación al contenido de las frases prima una perspectiva participativa y de receptores de información. En cambio, la idea de control por parte de las familias en cuanto a su capacidad de exigencia de rendición de cuentas es de mucha menor intensidad, pudiendo decir que el nivel de exigencia y supervisión está en parte restringido. También cabe destacar que el mayor grado de acuerdo entre los expertos se muestra en ítems que potencian una perspectiva de las familias como informadores y receptores privilegiados de los resultados de la evaluación. Mientras que existe menor grado de acuerdo cuando a las familias se les atribuye papeles más activos en la puesta en práctica de las políticas de evaluación.
