AIMS To estimate the prevalence of malnutrition in chronic obstructive pulmonary disease (COPD) patients hospitalized for exacerbation and to evaluate its clinical and prognostic influence on the exacerbation. SUBJECTS/METHODS The subjects were 78 consecutive patients with moderate-to-severe COPD who were admitted to hospital with a diagnosis of exacerbation. Nutritional status was assessed b...

INTRODUCTION Early pulmonary rehabilitation is recommended after a severe exacerbation of chronic obstructive pulmonary disease (COPD). However, this is difficult to implement, particularly for exercise training. High-flow nasal therapy (HFNT) may reduce the work of breathing and dyspnoea and may improve exercise tolerance. METHODS AND ANALYSIS This is a single-centre, prospective, controlled...

BACKGROUND This meta-analysis evaluated the effect of noninvasive, positive pressure ventilation on severe, stable chronic obstructive pulmonary disease (COPD). METHODS PUBMED, CNKI, Wanfang, EMBASE and the Cochrane trials databases were searched. Randomized controlled trials of patients with severe, stable COPD and receiving noninvasive positive pressure ventilation, compared with sham venti...

Razzaq et al, 2005 reported that the Assistment system was causing students to learn at the computer but we were not sure if that was simply due to students getting practice or more due to the "intelligent tutoring" that we created and force students to do if they get an item wrong. Our survey indicated that some students found being forced to do scaffolding sometimes frustrating. We were not s...

Since the implementation of the first HVDC thyristor valve at Eel River (Canada) in the early 1970’s, HVDC transmission has experienced tremendous growth. As power systems grow and become more integrated, interconnections to neighboring ac systems are becoming increasingly necessary to enhance stability, security of supply, flexibility and for other economic benefits. Primarily for stability re...

THE TECHNIQUE OF DETERMINATION OF STRUCTURAL PARAMETERS FROM FORCED VIBRATION TESTING Wai Fan Tsang This thesis details the results of an investigation into a technique for determination of "useful" structural parameters from forced vibration testing. The implementation of this technique to full scale civil engineering structures was achieved by several developments in the experimental and comp...

Sleep quality has been validated as an indicator well-being predictor delayed risk. At this article demonstrate interaction between psychological hardness risk insomnia in group students Herzen University period ...

In the Set Coincidence Game G(V, W), two players alternately choose elements not previously chosen from a finite, nonempty set V, and W is a given family of nonempty subsets of V (the ‘winning sets’). The winner is that player who first adds an element to the set of ‘chosen’ elements 5, so that S E W. This game is closely related to and generalizes Ringeisen’s Isolation Game on graphs. We devel...

This paper examines whether the forced resignation of managers of Dutch football teams leads to an improvement in the results. We find by analysing 12 years of football in the highest Dutch league that forced resignations are preceded by declines in team performance and followed by improvements in performance. However, the improvement in performance after appointing a new manager does not excee...

Hybrid laminates, such as fiber metal are increasingly used in engineering applications due to their outstanding damage tolerance and weight-specific performance. Prone vibrations, laminates have recently been complemented by viscoelastic elastomer layers order achieve a desired level of damping following the principles constrained layer damping. This paper presents an analytical modeling appro...
