To compare the diagnostic performance of lung ultrasound and bedside chest radiography (CXR) for the detection of various pathologic abnormalities in unselected critically ill patients, using thoracic computed tomography (CT) as a gold standard. Forty-two mechanically ventilated patients scheduled for CT were prospectively studied with a modified lung(More)
It is not known if proportional assist ventilation with load-adjustable gain factors (PAV+) may be used as a mode of support in critically ill patients. The aim of this study was to examine the effectiveness of sustained use of PAV+ in critically ill patients and compare it with pressure support ventilation (PS). Randomized study in the intensive care unit(More)
BACKGROUND AND OBJECTIVES Acute kidney injury (AKI) is a frequent complication in critically ill patients and sepsis is the most common contributing factor. We aimed to determine the risk factors associated with AKI development in patients with septic shock. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Observational cohort study consisted of consecutive(More)
STUDY OBJECTIVE Idiopathic pulmonary fibrosis (IPF) is a chronic, usually fatal lung disease of unknown etiology. A common feature is the presence of microscopic areas of epithelial cell dropout. Increased apoptosis of these cells could elucidate the speculative pathogenesis of the disease. Therefore, the aim of our study was to examine the expression of(More)
Although mechanical ventilation (MV) is a life-saving intervention for patients with acute respiratory distress syndrome (ARDS), it can aggravate or cause lung injury, known as ventilator-induced lung injury (VILI). The biophysical characteristics of heterogeneously injured ARDS lungs increase the parenchymal stress associated with breathing, which is(More)
Idiopathic pulmonary fibrosis (IPF) is a deadly disease, largely unresponsive to treatment with corticosteroids and immunosuppressives. The aim of this randomized, prospective, open-label study was to characterize the molecular effects of IFN-gamma-1b and colchicine, on biomarkers expression associated with fibrosis (TGF-beta, CTGF) and(More)
During pressure support ventilation (PS), an abrupt increase in ventilator pressure above the pre-set level is considered to signify expiratory muscle activity. However, relaxation of inspiratory muscles may also cause the same phenomenon, and this hypothesis has not been explored. The aim of this study is to examine the cause of this increase in ventilator(More)
BACKGROUND Pulmonary hypertension (PH) is characterized by pulmonary arterial remodeling that results in increased pulmonary vascular resistance, right ventricular (RV) failure, and premature death. Down-regulation of sarcoplasmic reticulum Ca(2+)-ATPase 2a (SERCA2a) in the pulmonary vasculature leads to perturbations in calcium ion (Ca(2+)) homeostasis and(More)
Background. Acute kidney injury (AKI) is a frequent complication of critically ill patients. The impact of different risk factors associated with this entity in the ICU setting is unknown. Objectives. The purpose of this research was to assess the risk factors associated with the development of AKI in critically ill patients by meta-analyses of(More)
To examine patient–ventilator asynchrony and sleep quality in non-sedated critically ill patients ventilated with proportional assist ventilation with load adjustable gain factors (PAV+) and pressure support (PSV). This was a randomized crossover physiological study conducted in an adult ICU at a tertiary hospital. Patients who exhibited patient–ventilator(More)
