Objetivou-se analisar as medidas de prevenção à pneumonia associada ventilação mecânica evidenciadas na literatura científica. Trata-se um estudo revisão integrativa. Para a elaboração da questão pesquisa integrativa, utilizou-se estratégia PICO. A presente foi feita mediante busca online nas bases dados Biblioteca Virtual em Saúde (BVS) no período 2015 06/2020. Após leitura criteriosa dos arti...

Currently available noninvasive methods for measuring inspiratory resistance (RI) are difficult to implement or interpret during assisted mechanical ventilation on account of the confounding effect of respiratory efforts (Pmus). We propose a simple method consisting of brief reductions in airway pressure (Paw) in the early part of the inflation phase (pulse). Paw, flow (V), and volume (V) are m...

AIMS The interaction between coronary β(2)-adrenoreceptors and segmental plaque burden is complex and poorly understood in humans. We aimed to validate intracoronary (IC) salbutamol as a novel endothelium-dependent vasodilator utilizing intravascular ultrasound (IVUS), and thus assess relationships between coronary β(2)-adrenoreceptors, regional plaque burden and segmental endothelial function....

BACKGROUND Statins can regress coronary atheroma and lower clinical events. Although pre-clinical studies suggest procalcific effects of statins in vitro, it remains unclear if statins can modulate coronary atheroma calcification in vivo. OBJECTIVES This study compared changes in coronary atheroma volume and calcium indices (CaI) in patients receiving high-intensity statin therapy (HIST), low...

Male, female and immature stages of Bucculatrix mirnae sp. n., from the Azapa Valley, coastal desert of northern Chile, are described and illustrated, under optical and scanning electron microscopy. The immature stages are associated with the shrub Baccharis salicifolia (Ruiz & Pav.) Pers. (Asteraceae). The larva is hypermetamorphic, having five instars and two feeding habits. The first, second...

The photodegradation behavior of a straight asphalt was investigated using a new method “photodegradation test of asphalt binder using pressed thin film samples”. Although the photodegradation caused by outdoor exposure is limited to the near surface, the results confirmed that the degree of degradation during 1 to 2 months is more severe than that by the pressure aging vessel (PAV) test, which...

We present Spitzer Space Telescope photometry of six short-period polars, EF Eri, V347 Pav, VV Pup, V834 Cen, GG Leo, and MR Ser. We have combined the Spitzer Infrared Array Camera (3.6–8.0 μm) data with the 2MASS JHKs photometry to construct the spectral energy distributions of these systems from the nearto mid-IR (1.235–8 μm). We find that five out of the six polars have
