This retrospective multicenter study compared microorganisms documented by quantitative cultures from bronchoscopic samples in episodes of ventilator-associated pneumonia (VAP) from three different institutions in Barcelona (B), Montevideo (M), and Seville (S). The observations were compared with the findings reported by Trouillet and coworkers (AJRCCM(More)
Dofetilide is currently recommended as second-tier therapy to maintain sinus rhythm in patients with paroxysmal atrial fibrillation (PAF) and normal left ventricular function, yet limited data support this recommendation. We examined the safety and efficacy of dofetilide in this setting through a retrospective chart review. We evaluated patients who had(More)
We have previously reported that dopamine increased active Na+ transport in rat lungs by upregulating the alveolar epithelial Na,K-ATPase. Here we tested whether alveolar epithelial cells produce dopamine and whether increasing endogenous dopamine production by feeding rats a 4% tyrosine diet (TSD) would increase lung liquid clearance. Alveolar Type II(More)
PURPOSE The purpose of this study was to evaluate the efficacy of verteporfin photodynamic therapy on the treatment of polypoidal choroidal vasculopathy. METHODS A prospective, nonrandomized institutional study was conducted involving 42 eyes of 38 patients with newly diagnosed symptomatic polypoidal choroidal vasculopathy treated exclusively with(More)
Two-dimensional images computed from three-dimensional optical coherence tomography (OCT) data are intrinsically aligned with it, allowing to accurately position a retinal OCT scan within the ocular fundus. In this work, we aim to compute an OCT fundus reference image with improved retinal vasculature extension and contrast over traditional approaches.(More)
Lung transplantation is a widely accepted therapeutic option for patients with end-stage lung disease. However, despite the significant medical progress achieved since the first human lung transplant was performed in 1963, perioperative and long-term patient outcomes are still jeopardised by a variety of complications. Infection and rejection are among the(More)
