El perfil profesional de los formadores de formación continua en España
2011
El objetivo de este trabajo es analizar y describir los perfiles profesionales del formador de formación continua en España. Con este propósito se ha elaborado un cuestionario estructurado que se ha aplicado de forma presencial a una muestra de 606 formadores a nivel nacional. El cuestionario ha proporcionado información sobre aspectos como el estatus socio-laboral del formador, el grado de profesionalización y la importancia de las competencias profesionales de los formadores. La información recabada ha sido analizada mediante métodos multivariantes para determinar los perfiles profesionales dominantes. El análisis cuantitativo incluye el Análisis de Componentes Principales Categóricos (CA…
Early stage diagnosis of programmed cell death (apoptosis) using electroanalysis: Nanomaterial and methods overview
2017
Timely monitoring of apoptosis can effectively assist early diagnosis of related diseases and continuous evaluation of the efficacy of drugs. Therefore, developing advanced methods for apoptosis evaluation has attracted more and more attention. In addition, the increased demand for understanding the early stages of apoptosis is pushing the envelope for solutions in early instance real-time monitoring of death kinetics. In this review, various types of electro-analytical methods for detection of apoptosis were discussed. The emphasis is placed in diagnosis of apoptosis based on cyto-, immune-, geno-, apta-, and peptide based biosensing strategies. In the first part of review, various electro…
On Using the Theory of Regular Functions to Prove the ε-Optimality of the Continuous Pursuit Learning Automaton
2013
Published version of a chapter in the book: Recent Trends in Applied Artificial Intelligence. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-38577-3_27 There are various families of Learning Automata (LA) such as Fixed Structure, Variable Structure, Discretized etc. Informally, if the environment is stationary, their ε-optimality is defined as their ability to converge to the optimal action with an arbitrarily large probability, if the learning parameter is sufficiently small/large. Of these LA families, Estimator Algorithms (EAs) are certainly the fastest, and within this family, the set of Pursuit algorithms have been considered to be the pioneering schemes. The…
Attitudes of dental implantologists in Spain to prescribing antibiotics, analgesics and anti-inflammatories in healthy patients
2019
Background The implantologists frequently prescribe antibiotics, analgesics and anti-inflammatories in dental implant surgery. The aims of this study were to evaluate the attitudes of implantologists in Murcia (Spain) to prescribing antibiotics, analgesics and anti-inflammatories in healthy patients during different implant dentistry procedures, and to see how these are influenced by individual dentist’s academic level, professional experience, and ongoing training (attending courses or reading scientific literature on medication use) Material and Methods This cross-sectional study included a total of 200 implantologists from the Murcia area (Spain), who each completed a two-page questionna…
Helmet continuous positive airway pressure and prone positioning: A proposal for an early management of COVID-19 patients
2020
In late December 2019, clusters of patients with interstitial pneumonia of unknown cause were reported by some local health facilities in Wuhan (China). The Chinese Centre for Disease Control conducted an epidemiologic and etiologic investigation, leading to the identification of a novel coronavirus (SARS-CoV-2).1, 2 On March 11th, the World Health Organization (WHO) declared the novel coronavirus disease (COVID-19) a pandemic. In the area of Wuhan, COVID-19 mainly affected male patients (around 60%), with a median age of about 50 years; 40% of patients developed Acute Respiratory Distress Syndrome (ARDS) 5% requiring intensive care. The mortality rate was around 2%.3, 4 However, Grasselli …
Blood pressure responsiveness to obstructive events during sleep after chronic CPAP
2003
The aim of this study was to investigate whether chronic continuous positive airway pressure (CPAP) affects blood pressure (BP) responsiveness to obstructive events occurring on the first night of CPAP withdrawal in obstructive sleep apnoea (OSA) after chronic treatment. Thirteen male subjects with severe OSA underwent nocturnal polysomnography with beatbybeat BP monitoring before treatment and after 4.9±3.4 months of home CPAP (mean daily use 5.1±1.7 h). Variations in oxyhaemoglobin saturation (Δ S a,O2), systolic (Δ P s), and diastolic (Δ P d) BP within nonrapid eye movement apnoeas and hypopnoeas were measured on a sample of pre and posttreatment events. In addition, a pretreatment s…
Recommendations for the management of patients with obstructive sleep apnoea and hypertension.
2013
This article is aimed at addressing the current state-of-the-art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnoea (OSA) in cardiovascular (in particular hypertensive) patients, as well as for the management of cardiovascular diseases (in particular arterial hypertension) in OSA patients. The present document is the result of work performed by a panel of experts participating in the European Union COST (Cooperation in Scientific and Technological research) Action B26 on OSA, with the endorsement of the European Respiratory Society and the European Society of Hypertension. In particular, these recommendations …
A New Configuration for Helmet Continuous Positive Airway Pressure Allowing Tidal Volume Monitoring
2020
We performed a bench and human study to test the hypothesis that a ventilator can accurately estimate Vt when a helmet is used in CPAP mode in a single limb configuration with an intentional leak port placed at the helmet expiratory port. We have recently demonstrated the effectiveness of this setup in bilevel mode
Sleep, sleep-disordered breathing and metabolic consequences.
2009
Sleep profoundly affects metabolic pathways. In healthy subjects, experimental sleep restriction caused insulin resistance (IR) and increased evening cortisol and sympathetic activation. Increased obesity in subjects reporting short sleep duration leads to speculation that, during recent decades, decreased sleeping time in the general population may have contributed to the increasing prevalence of obesity. Causal inference is difficult due to lack of control for confounders and inconsistent evidence of temporal sequence. In the general population, obstructive sleep apnoea (OSA) is associated with glucose intolerance. OSA severity is also associated with the degree of IR. However, OSA at bas…
Cardiovascular Events in Moderately to Severely Obese Obstructive Sleep Apnea Patients on Positive Airway Pressure Therapy.
2016
<b><i>Background:</i></b> In moderately to severely obese patients with obstructive sleep apnea (OSA), the effects of long-term positive airway pressure (PAP) treatment on cardiovascular risk are poorly defined. <b><i>Purpose:</i></b> To assess the effect of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) on the occurrence of cardiovascular events in obese OSA patients. <b><i>Methods:</i></b> We performed a noninterventional observational study in obese OSA patients recruited between 2007 and 2010 at the Sleep Center, University of Grenoble, treated with CPAP or NIV, and followed for 5.6 year…
