Procalcitonin is not sufficiently reliable to be the sole marker of neonatal sepsis of nosocomial origin
No full textBackground: It has recently been suggested that serum procalcitonin (PCT) is of value in the diagnosis of neonatal sepsis, with varying results. The aim of this prospective multicenter study was to assess the usefulness of PCT as a marker of neonatal sepsis of nosocomial origin. Methods: One hundred infants aged between 4 and 28 days of life admitted to the Neonatology Services of 13 acute-care teaching hospitals in Spain over 1-year with clinical suspicion of neonatal sepsis of nosocomial origin were included in the study. Serum PCT concentrations were determined by a specific immunoluminometric assay. The reliability of PCT for the diagnosis of nosocomial neonatal sepsis at the time of suspicion of infection and at 12–24 h and 36–48 h after the onset of symptoms was calculated by receiver-operating characteristics (ROC) curves. The Youden's index (sensitivity + specificity - 1) was used for determination of optimal cutoff values of the diagnostic tests in the different postnatal periods. Sensitivity, specificity, and the likelihood ratio of a positive and negative result with the 95% confidence interval (CI) were calculated. Results: The diagnosis of nosocomial sepsis was confirmed in 61 neonates. Serum PCT concentrations were significantly higher at initial suspicion and at 12–24 h and 36–48 h after the onset of symptoms in neonates with confirmed sepsis than in neonates with clinically suspected but not confirmed sepsis. Optimal PCT thresholds according to ROC curves were 0.59 ng/mL at the time of suspicion of sepsis (sensitivity 81.4%, specificity 80.6%); 1.34 ng/mL within 12–24 h of birth (sensitivity 73.7%, specificity 80.6%), and 0.69 ng/mL within 36–48 h of birth (sensitivity 86.5%, specificity 72.7%). Conclusion: Serum PCT concentrations showed a moderate diagnostic reliability for the detection of nosocomial neonatal sepsis from the time of suspicion of infection. PCT is not sufficiently reliable to be the sole marker of sepsis, but would be useful as part of a full sepsis evaluation.López Sastre, J.B., Pérez Solís, D., Roqués Serradilla, V., Fernández Colomer, B., Coto Cotallo, G.D., Krauel Vidal, X., Narbona López, E., García del Río, M., Sánchez Luna, M., Belaustegui Cueto, A., Moro Serrano, M., Urbón Artero, A., Álvaro Iglesias, E., Cotero Lavin, A., Martínez Vilalta, E., Jimenez Cobos, B
Vernacular and Fertile. The Pantano Masseria di Puglia, Italia
No full text[EN] The Metropolis has attracted the attention of most architects by making them forget about rural spaces. The recent health crisis seems to have restored sensitivity to the rural environment as well as to life in contact with nature, reopening the field of reflection to global challenges such as migrations or climate and demographic changes whose effects are more evident in the countryside than in the cities. In this context, the possibility arises of analysing and interpreting the Masseria del Pantano as a model of popular architecture that could serve as a typological, urban or architectural example for the development of environmentally responsible architecture. The research method chosen for the elaboration of the work has included several phases. Firstly, an approach to the subject with the reading of the main bibliographic texts, a second stage a specific bibliography has been prepared and once this information has been contrasted. We visit the site to collect data that allows us to analyze and interpret the building. The cataloguing of peasant vernacular architecture, almost always anonymous, could perhaps be reused as design material. The beauty that productive landscapes offer us, due to their intelligence, their timelessness, their sensitivity to the land and their link, even today, with mother nature, must be the basis for the future, so that they can nourish us in a respectful way. The conclusions aim to understand the logic used by anonymous peasants in adapting their homes to the landscape. The intention of this work is not only to recognize the value of what exists, but also to find strategies capable of influencing the construction of contemporary housing.Cotallo, F.;Munafò, M.

Janus: An FPGA-Based System for High-Performance Scientific Computing
No full text© 2009, IEEE. Artículo firmado por 23 autores. We thank M. Lena and S. Sialino for their outstanding support during the commissioning of the first JANUS system.This paper describes JANUS, a modular massively parallel and reconfigurable FPGA-based computing system. Each JANUS module has a computational core and a host. The computational core is a 4x4 array of FPGA-based processing elements with nearest-neighbor data links. Processors are also directly connected to an I/O node attached to the JANUS host, a conventional PC. JANUS is tailored for, but not limited to, the requirements of a class of hard scientific applications characterized by regular code structure, unconventional data manipulation instructions and not too large data-base size. We discuss the architecture of this configurable machine, and focus on its use on Monte Carlo simulations of statistical mechanics. On this class of application JANUS achieves impressive performances: in some cases one JANUS processing element outperfoms high-end PCs by a factor ≈1000. We also discuss the role of JANUS on other classes of scientific applications.Depto. de Física TeóricaFac. de Ciencias FísicasTRUEpu
Spin-glass transition of the three-dimensional heisenberg spin glass
No full text© 2006 American Physical Society. Alonso for discussions, and BIFI (U. Z.) and Marenostrum (Barcelona Supercomputing Center) for computing time. We were partly supported by BSCH—UCM, by DGA– Spain (M. C.-A and S. P.-G.), and by MEC (Spain) through Contracts No. BFM2003-08532 and No. FIS2004-05073.It is shown, by means of Monte Carlo simulation and finite size scaling analysis, that the Heisenberg spin glass undergoes a finite-temperature phase transition in three dimensions. There is a single critical temperature, at which both a spin glass and a chiral glass ordering develop. The Monte Carlo algorithm, adapted from lattice gauge theory simulations, makes it possible to thermalize lattices of size L 32, larger than in any previous spin-glass simulation in three dimensions. High accuracy is reached thanks to the use of the Marenostrum supercomputer. The large range of system sizes studied allows us to consider scaling corrections.BSCH-UCM, SpainDGA– Spain (M.

An educational proposal in 4th grade based on collaboration-opposition games under the cooperative learning model to promote group cohesion
No full textEl aprendizaje cooperativo es un modelo pedagógico que puede servir como herramienta educativa no sólo para
favorecer el proceso de enseñanza-aprendizaje del alumnado sino su cohesión dentro de un grupo-clase. Objetivos: El objetivo
principal de la investigación fue conocer los niveles de cohesión de un grupo de 4º curso de Educación Primaria y crear una
propuesta educativa basada en juegos de colaboración-oposición bajo el modelo de aprendizaje cooperativo para fomentar la
cohesión social y la cohesión tarea del grupo. Métodos: La muestra del estudio estuvo compuesta por un total de 24 alumnos
(8 chicas y 16 chicos) del colegio “José Luis Cotallo” de 4º de Educación Primaria con unas edades comprendidas entre 9 y 11
años. Para conocer los niveles de cohesión se utilizó el cuestionario The Youth Sport Environment Questionnaire-YSEQ
adaptado por Leo et al. (2023). Resultados y discusión: Los resultados del trabajo expusieron unos valores medios de
cohesión social (M=7.16) y tarea (M=7.86) positivos, aunque podrían mejorarse. Una vez obtenidos los resultados de los
niveles de cohesión, se propuso un programa de intervención basado en juegos de colaboración-oposición. Dicha propuesta de
intervención constaba de seis clases. Los juegos se caracterizaban por la realización de actividades motrices mientras se
desarrollaba la cooperación de los niños/as y realizando actividades que implicaban cognitivamente al alumnado y con un
fondo didáctico para el fomento de la transmisión de valores. Conclusiones: Mediante esta propuesta de programa de
intervención se pretendía proponer el uso del aprendizaje cooperativo como herramienta docente en la educación primaria para
paliar posibles niveles anómalos de las relaciones sociales entre el alumnado, fomentando la cohesión grupal.
Palabras clave: Aprendizaje cooperativo; juegos de colaboración-oposición; educación primaria; educación físicaCooperative learning is a pedagogical model that can serve as an educational tool not only to favour the
teaching-learning process of students but also their cohesion within a group-class.. Aim: The main objective of the research
was to find out the levels of cohesion of a group of 4th grade of Primary Education and to create an educational proposal
based on collaborative-opposition games under the model of cooperative learning to promote social cohesion and group task
cohesion. Methods: The Youth Sport Environment Questionnaire-YSEQ adapted by Leo et al. (2023) was used to determine
the levels of cohesion. Results & discussion: The results of the work showed positive mean values of social cohesion
(M=7.16) and task (M=7.86), although they could be improved. Once the results of the cohesion levels were obtained, an
intervention programme based on collaboration-opposition games was proposed. This intervention proposal consisted of six
classes. The games were characterised by the carrying out of motor activities while developing the children's cooperation and
carrying out activities that cognitively involved the pupils and with a didactic background to promote the transmission of
values. Conclusions: This intervention programmer proposal aims to propose the use of cooperative learning as a teaching
tool in primary education to alleviate possible anomalous levels of social relations among pupils, promoting group cohesion.
