Serum IL-6 is increased in patients with acute kidney injury (AKI) and is associated with prolonged mechanical ventilation and increased mortality. Inhibition of IL-6 in mice with AKI reduces lung injury associated with a reduction in the chemokine CXCL1 and lung neutrophils. Whether circulating IL-6 or locally produced lung IL-6 mediates lung injury after AKI is unknown. We hypothesized that c...
To study the mechanisms responsible for ischemia-reperfusion lung injury, we developed an anesthetized rabbit model in which the effects of lung deflation, lung inflation, alveolar gas composition, hypothermia, and neutrophils on reperfusion pulmonary edema could be studied. Rabbits were anesthetized and ventilated, and the left pulmonary hilum was clamped for either 2 or 4 h. Next, the left lu...
Analysis of risk factors of acute kidney injury in perioperative patients after lung transplantation
Background: This study sought to examine the factors influencing acute kidney injury (AKI) in perioperative period after lung transplantation (LT).
Lung epithelial and endothelial cell death accompanied by inflammation contributes to hyperoxia-induced acute lung injury (ALI). Impaired resolution of ALI can promote and/or perpetuate lung pathogenesis, including fibrosis. Previously, we have shown that the transcription factor Nrf2 induces cytoprotective gene expression and confers protection against hyperoxic lung injury, and that Nrf2-medi...
Acute kidney injury (AKI) contributes greatly to morbidity and mortality in critically ill adults and children. Patients with AKI who subsequently develop lung injury are known to suffer worse outcomes compared with patients with lung injury alone. Isolated experimental kidney ischemia alters distal lung water balance and capillary permeability, but the effects of such an aberration on subseque...
OBJECTIVES To determine the incidence, risk factors, and outcome of transfusion-related acute lung injury in a cohort of critically ill patients. DESIGN In a retrospective cohort study, patients with transfusion-related acute lung injury were identified using the consensus criteria of acute lung injury within 6 hrs after transfusion. Inclusion criterion was a length of intensive care unit adm...
purpose: since explosive blasts continue to cause casualties in both civil and military environments, there is a need for an understanding of the mechanisms of blast trauma at the human organ level, plus a more detailed predictive methodology. the primary goal of this research was to develop a finite element model capable of predicting primary blast injury to the lung so as to assist in the dev...
Lung injury especially acute respiratory distress syndrome (ARDS) can be triggered by diverse stimuli, including fatty acids and microbes. ARDS affects thousands of people worldwide each year, presenting high mortality rate and having an economic impact. One of the hallmarks of lung injury is edema formation with alveoli flooding. Animal models are used to study lung injury. Oleic acid-induced ...
Objective(s): Increasing cytokines and reactive oxygen species (ROS) during ischemia reperfusion (I-R) leads to the lung damage. Adalimumab (Ada) is a potent tumor necrosis factor-alpha (TNF-α) inhibitor agent. We aimed to evaluate whether Ada would prevent the lung tissue from damage development over the I-R process. Materials and Methods:Twenty seven Wistar albino male rats were divided into...
OBJECTIVE Transfusion-related acute lung injury is the leading cause of transfusion-related mortality. A prospective study using electronic surveillance was conducted at two academic medical centers in the United States with the objective to define the clinical course and outcomes in transfusion-related acute lung injury cases. DESIGN Prospective case study with controls. SETTING University...
