Results 36 patients were included. Among them, 13 (36 %) had grade 3 PGD. EVLWi was significantly higher in the grade 3 PGD group at ICU admission, day one and at day 2. A cut-off value of 14 ml/kg of EVLWi at admission predicts the progression to grade 3 PGD with a sensitivity of 82% and a specificity of 77% and was significantly associated with the need for rescue therapy for severe hypoxemia...

Background: Lung Ultrasound (LUS) has recently become an important method for diagnostic examination and monitoring of lung disease. Many diseases, such as respiratory distress syndrome (RDS), transient tachypnea the newborn (TTNB), pneumonia were diagnosed by chest X-ray, but can now easily be with LUS. LUS many advantages over X-ray including accuracy, reliability, low cost, radiation free, s...

Pulmonary ultrasound is a non-invasive bedside resource that has showed to be useful for the assessment of patients presenting with respiratory insufficiency as well diagnosis several pleural and other pulmonary pathologies. The score (LUS) semi quantitative scale measures loss aeration cause by many pathologic conditions. Our primary objective was describe factors associated death hospitalizat...

Cultivated flax (Linum usitatissimum L.) is an important plant valuable for industry. Some flax lines can undergo heritable phenotypic and genotypic changes (LIS-1 insertion being the most common) in response to nutrient stress and are called plastic lines. Offspring of plastic lines, which stably inherit the changes, are called genotrophs. MicroRNAs (miRNAs) are involved in a crucial regulator...

Objectives To evaluate the accuracy of a new COVID-19 prognostic score based on lung ultrasound (LUS) and previously validated variables in predicting critical illness. Methods We conducted single-center retrospective cohort development internal validation study Worsening Score (COWS), combination COVID-GRAM (GRAM) LUS. Adult patients admitted to emergency department (ED) were enrolled. Ten ide...

In this work, a novel method is described for the preconcentration of Pb2+, Cd2+ and Zn2+ ions in environmental samples using uniform silanized mesopor (LUS-1) functionalized by ethylenediamine groups as a new extractant. The determination of ions is done by inductively coupled plasma optical emission spectrometry (ICP-OES). The extraction time and efficiency, p...

Mesoporous silica LUS-1 (Laval University Silica) was successfully functionalized by propyl sulfonic acid and was used as a recyclable catalyst for the synthesis of acridine-1,8-diones via a pseudo four component reaction of aromatic aldehydes, dimedone and ammonium acetate (or anilines). The excellent yields, short reaction time, simple work-up procedure, and environmentally friendly condition...

vanadium supported on highly ordered nanoporous silica (vox-lus-1) was synthesized and characterized by xrd, nitrogen adsorption‑desorption isotherms and uv-visible spectrophotometer. direct oxidation of benzene to phenol in liquid phase by h2o2 peroxide were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the ph...

Despite the many advantages of lung ultrasound (LUS) in diagnosis and management patients with dyspnea, its adoption among hospitalists has been slow. We performed semi-structured interviews hospitals from four diverse health systems United States to understand determinants within a range clinical settings. used diffusion innovation theory guide framework analysis data. Of 27 invited, we 22 typ...
