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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
