A Decision Tree to Assess Short-Term Mortality After an Emergency Department Visit for an Exacerbation of COPD: a Cohort Study
(Biomed Central, 2015-12-22)Background: Creating an easy-to-use instrument to identify predictors of short-term (30/60-day) mortality after an exacerbation of chronic obstructive pulmonary disease (eCOPD) could help clinicians choose specific measures ... -
Accurate Determination of the Q Quality Factor in Magnetoelastic Resonant Platforms for Advanced Biological Detection
(MDPI, 2018-03)The main parameters of magnetoelastic resonators in the detection of chemical (i.e., salts, gases, etc.) or biological (i.e., bacteria, phages, etc.) agents are the sensitivity S (or external agent change magnitude per Hz ... -
Analysis of latent tuberculosis and mycobacterium avium infection data using mixture models
(BioMed Central, 2006-09-28)Background: Estimation of the frequency of latent tuberculosis infection (LTBI) is difficult in areas with low tuberculosis infection rates and high exposure to non-tuberculous mycobacteria (NTM), including BCG vaccination. ... -
Chronic Obstructive Pulmonary Disease Subtypes. Transitions over Time
(Public Library Science, 2016-09-09)Background Although subtypes of chronic obstructive pulmonary disease are recognized, it is unknown what happens to these subtypes over time. Our objectives were to assess the stability of cluster-based subtypes in ... -
Development of appropriateness explicit criteria for cataract extraction by phacoemulsification
(BioMed Central, 2006-03)Background: Consensus development techniques were used in the late 1980s to create explicit criteria for the appropriateness of cataract extraction. We developed a new appropriateness of indications tool for cataract ... -
Global Self-Regulation of the Cellular Metabolic Structure
(Public Library of Science, 2010-03-02)Background: Different studies have shown that cellular enzymatic activities are able to self-organize spontaneously, forming a metabolic core of reactive processes that remain active under different growth conditions while ... -
Goal-Oriented p-Adaptivity using Unconventional Error Representations for a 1D Steady State Convection-Diffusion Problem
(Elsevier, 2017)This work proposes the use of an alternative error representation for Goal-Oriented Adaptivity (GOA) in context of steady state convection dominated diffusion problems. It introduces an arbitrary operator for the computation ... -
ICCS 2017 Workshop on Agent-Based Simulations, Adaptive Algorithms and Solvers
(Elsevier, 2017)This workshop seeks to integrate results from different domains of computer science, computational science, and mathematics. We welcome simulation papers, either hard simulations using finite element or finite difference ... -
Implicacion de los profesionales de atencion primaria en el programa de deteccion precoz de cancer colorrectal del Pais Vasco
(Ministerio de Sanidad, Consumo y Bienestar Social, 2021-01-26)OBJETIVO: El Gobierno Vasco (Espana) aprobo en 2008 un programa de deteccion del cancer colorrectal de base poblacional en Atencion Primaria. Se ha logrado una cobertura del 100% con una tasa de participacion media del ... -
On a formula of Thompson and McEnteggert for the adjugate matrix
(Elsevier, 2022)For an eigenvalue lambda(0) of a Hermitian matrix A, the formula of Thompson and McEnteggert gives an explicit expression of the adjugate of lambda I-0 - A, Adj(lambda I-0 - A), in terms of eigenvectors of Afor lambda(0) ... -
Predictive factors over time of health-related quality of life in COPD patients
(BMC, 2020-06-05)BACKGROUND: Health-related quality of life (HRQoL) should be seen as a tool that provides an overall view of the general clinical condition of a COPD patient. The aims of this study were to identify variables associated ... -
Subtypes of Patients Experiencing Exacerbations of COPD and Associations with Outcomes
(Public Library Science, 2014-06-03)Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could ... -
Symmetrical Motifs in Young Children’s Drawings: A Study on Their Representations of Plant Life
(MDPI, 2018-12-29)Young children love drawing; this is without question. Besides that, drawings are also of interest to scholars and educators, since they seem to provide food for thought regarding children's conceptual development during ... -
The IRYSS-COPD appropriateness study: objectives, methodology, and description of the prospective cohort
(BioMed Central, 2011-11)Background: Patients with chronic obstructive pulmonary disease (COPD) often experience exacerbations of the disease that require hospitalization. Current guidelines offer little guidance for identifying patients whose ... -
The nucleus does not significantly affect the migratory trajectories of amoeba in two-dimensional environments
(Springer Nature, 2019-11-08)For a wide range of cells, from bacteria to mammals, locomotion movements are a crucial systemic behavior for cellular life. Despite its importance in a plethora of fundamental physiological processes and human pathologies, ... -
The Number of Catalytic Elements Is Crucial for the Emergence of Metabolic Cores
(Public Library of Science, 2009-10-19)Background: Different studies show evidence that several unicellular organisms display a cellular metabolic structure characterized by a set of enzymes which are always in an active state (metabolic core), while the rest ... -
Use of generalised additive models to categorise continuous variables in clinical prediction
(BioMed Central, 2013-06-26)Background: In medical practice many, essentially continuous, clinical parameters tend to be categorised by physicians for ease of decision-making. Indeed, categorisation is a common practice both in medical research and ... -
What mechanism of niche segregation allows the coexistence of sympatric sibling rhinolophid bats?
(Biomed Central, 2012)Introduction: Our purpose was to assess how pairs of sibling horseshoe bats coexists when their morphology and echolocation are almost identical. We collected data on echolocation, wing morphology, diet, and habitat use ...
