“Background and objectivePrevious
studies have demonstrated that positive blood culture could contribute to poorer outcomes in patients with pneumonia. However, the impact of positive blood culture on the outcomes of patients with sepsis-induced acute respiratory distress syndrome (ARDS) has not been evaluated.
MethodsAn observational study that prospectively screened 4861 patients admitted to medical or surgical intensive care units (ICUs) of a tertiary referral centre was performed.
ResultsAmong 4861 admitted patients, 146 diagnosed with sepsis-induced ARDS were enrolled (mean age: 66.1 years). Lower PaO2/FiO(2), decreased respiratory Selleck MLN4924 system compliance, and higher lung injury scores (LIS) on the day of ARDS diagnosis were associated with positive blood cultures (n=68) rather than negative blood cultures (n=78). There was no relationship between positive blood culture and in-hospital
mortality. Kaplan-Meier estimates also revealed that positive blood culture was not associated with 60-day mortality but with an increased length of stay in the hospital and in the ICU (P=0.007 and P=0.016, respectively). Using multivariate logistic regression, higher LIS was independently associated with positive blood culture. In addition, chronic pulmonary disease, lower platelet count, higher LIS, and the development of shock on the diagnosis of ARDS, were independent risk factors for in-hospital mortality.
ConclusionsThis study suggests that the Nutlin-3 presence of positive blood culture is not associated with increased mortality; however, the mean durations of hospital and ICU stays in patients with sepsis-induced ARDS are increased.”
“The present study characterized
viral nervous necrosis in sea cage-reared adult spotted coralgroupers (Plectropomus GSK1904529A in vivo maculatus). Histopathological study showed extensive vacuolation and neuronal necrosis of the olfactory bulb and the optic lobe of the forebrain and the inner and outer nuclear layer of retina. Mild necrosis was observed in the spinal cord. Homogeneous intranuclear inclusion bodies were noted in the hyperplastic and hypertrophic glandular epithelial cells of the swim bladder suggesting viral etiology. Etiological diagnosis of VNN was confirmed by RT-PCR, immunohistochemistry and in situ hybridization. The immunohistochemistry and in situ hybridization gave strongly positive staining in the same area of the infected cells of the brain, spinal cord and retina correlating with histopathological changes. No positive reaction was detectable in the affected gas glandular epithelium and other organs, confirming the consistent neurotropism of this nodavirus. Nodavirus was mainly detected in the olfactory bulb of the brain. The result suggests nasal transmission was the major route of infection. (C) 2009 Elsevier Ltd.
