PURPOSE To investigate the diagnostic performance of Doppler echocardiography (DE) in predicting the outcome of weaning from mechanical ventilation in patients without overt cardiac disease. METHODS Fifty critical care noncardiac patients who fulfilled predetermined criteria for weaning underwent DE before and at the end of spontaneous breathing trial(More)
Two colistin-susceptible/colistin-resistant (Col(s)/Col(r)) pairs of Acinetobacter baumannii strains assigned to international clone 2, which is prevalent worldwide, were sequentially recovered from two patients after prolonged colistin administration. Compared with the respective Col(s) isolates (Ab248 and Ab299, both having a colistin MIC of 0.5 μg/ml),(More)
AIM To investigate whether there is a significant relationship between an increased frequency of exacerbations and the rate of forced expiratory volume in 1s (FEV(1)) decline in COPD patients. METHODS-MEASUREMENTS: About 102 COPD patients (44 smokers, 58 ex-smokers) participated in a 3-year prospective study. Exacerbations were identified as worsening of(More)
OBJECTIVES Outbreaks caused by linezolid-resistant (LR) enterococci remain rare. We report the epidemiological and molecular characteristics of the multiclonal dissemination of LR enterococci in the intensive care unit (ICU) of a Greek hospital. METHODS All LR enterococcal isolates recovered from patients hospitalized in the ICU of the University Hospital(More)
BACKGROUND Erlotinib is a Human Epidermal Growth Factor Receptor Type 1/tyrosine kinase (EGFR) inhibitor which is used for non-small-cell lung cancer treatment. Despite that erlotinib is considered to have a favorable safety profile, adverse events such as interstitial lung disease (ILD) were reported in pivotal studies. The authors report the first(More)
Colistin pharmacokinetics were prospectively studied after intravenous administration of colistin methanesulphonate in critically ill patients without central nervous system infection (controls, n = 5) and in patients with external ventricular drain-associated ventriculitis after intravenous administration (EVDViv, n = 3) or combined(More)
INTRODUCTION Two small randomized controlled trials have suggested beneficial effects of antibiotic treatment in patients with ventilator-associated tracheobronchitis (VAT). The primary aim of this study is to determine the impact of appropriate antibiotic treatment on transition from VAT to ventilator-associated pneumonia (VAP) in critically ill patients.(More)
Sepsis is a stressful physical condition, and at the acute phase, overstimulation of the sympathetic nervous system may occur; these events have the potential to induce cardiomyopathy. Takotsubo cardiomyopathy (TTC) is a form of catecholamine-induced cardiomyopathy, which occurs very rarely in sepsis. However, TTC management in critically ill patients with(More)
BACKGROUND T lymphocytes and especially the subpopulations of CD8+ cells are believed to have a key role in COPD pathophysiology, but there are only few data regarding the role of these cells in COPD exacerbation. AIM We aimed to study prospectively changes of CD8+ T-lymphocyte subpopulations in the sputum of COPD patients at the onset of mild(More)
OBJECTIVE To investigate whether the use of pravastatin reduces the frequency of ventilator-associated pneumonia and whether it is related to favorable outcomes in critical care patients. DESIGN Two-center, two-arm, randomized, open-label, controlled trial. SETTING University Hospital and General Hospital of Larissa, Greece. PATIENTS Consecutive(More)
