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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
