BACKGROUND: Although there have been studies regarding the role of nebulized colistin as adjunctive therapy of ventilator-associated pneumonia (VAP) caused by carbapenem-resistant Acinetobacter baumannii (CRAB), a paucity of information on the efficacy of nebulized colistin as monotherapy is available. METHODS: We retrospectively reviewed 219 patients with VAP caused by CRAB treated with either intravenous (n=93) or nebulized colistin (n=126), from March 2010 to November 2015...

BACKGROUND AND PURPOSE: Neuroinflammation is initiated by a variety of stimuli including infections, sepsis, neurodegenerative diseases or traumatic brain injury and if not adequately controlled can lead to various degrees of neuronal damage and behavioural impairment. A critical event in the initial steps of inflammation is neutrophil extravasation. Semicarbazide sensitive amine oxidase (SSAO, also known as vascular adhesion protein 1 or VAP-1) regulates neutrophil adhesion and extravasation...

OBJECTIVE: Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of IBD. This clinical association is linked pathologically to the recruitment of mucosal T cells to the liver, via vascular adhesion protein (VAP)-1-dependent enzyme activity. Our aim was to examine the expression, function and enzymatic activation of the ectoenzyme VAP-1 in patients with PSC. DESIGN: We examined VAP-1 expression in patients with PSC, correlated levels with clinical characteristics and determined the functional consequences of enzyme activation by specific enzyme substrates on hepatic endothelium...

Seminal plasma removal is routine in goat sperm cryopreservation protocols. The classical washing procedure designed to accomplish this usually leaves the pellet resulting from use of this procedure contaminated with dead sperm, debris, and cells other than sperm. This contamination negatively affects viability of sperm after cryopreservation. The present research was conducted to compare the effect on chilled and frozen-thawed goat sperm of the classical washing method to that of a selective washing method involving density gradient centrifugation (DGC)...

Ventilator-associated pneumonia (VAP) is a frequent complication of severe burn injury. Comparing the current ventilator-associated event-possible VAP definition to the pre-2013 VAP definition, we identified considerably fewer VAP cases in our burn ICU. The new definition does not capture many VAP cases that would have been reported using the pre-2013 definition. Infect Control Hosp Epidemiol 2017;1-3.

Tuberculosis is kind of common chronic infectious disease, of which the pathogenic bacterium is mainly Mycobacterium tuberculosis (MTB). One who is suffering severe tuberculosis may be ended with cardio-pulmonary function damage or cardio-pulmonary failure. This disease is of higher risks of complications or even high death rate, which is seriously challenging people's health and life. When a tuberculosis patient is accompanied with respiratory failure, which means the disease has developed into the late stage, on this occasion the optimal treatment program is to use mechanical ventilation to improve the respiratory failure condition...

Amongst the recognized classes of naturally occurring antimicrobials, human host defense peptides are an important group with an advantage (given their source) that they should be readily translatable to medicinal products. It is also plausible that truncated versions will display some of the biological activities of the parent peptide, with the benefit that they are less costly to synthesize using solid-phase chemistry. The host defense peptide, LL-37, and two truncated mimetics, KE-18 and KR-12, were tested for their inhibitory effects and antibiofilm properties against Candida albicans, Staphylococcus aureus, and Escherichia coli, microorganisms commonly implicated in biofilm-related infections such as ventilator-associated pneumonia (VAP)...

Background: The effects of weather variability on seasonal influenza among different age groups remain unclear. Objectives: The comparative study aims to explore the differences in the associations between weather variability and seasonal influenza, and growth rates of seasonal influenza epidemics among different age groups in Queensland, Australia. Methods: Three Bayesian spatiotemporal conditional autoregressive models were fitted at postal area level to quantify the relationships between seasonal influenza and monthly minimum temperature (MIT), monthly vapour pressure (VAP), school calendar pattern and Index of Relative Socio-Economic Advantage and Disadvantage for three age groups (<15, 15-64 and 65+ years)...

The use of vancomycin minimum inhibitory concentration (MIC) as an outcome predictor in patients with methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia has become an important topic for debate in the last few years. Given these previous results, we decided to investigate whether MICs to vancomycin or daptomycin had any effect on the evolution of patients with ventilator-associated pneumonia (VAP) due to MSSA. An observational, retrospective, multicenter study was conducted among patients with MSSA VAP...

StAR-related lipid transfer domain-3 (STARD3) is a sterol-binding protein that creates endoplasmic reticulum (ER)-endosome contact sites. How this protein, at the crossroad between sterol uptake and synthesis pathways, impacts the intracellular distribution of this lipid was ill-defined. Here, by using in situ cholesterol labeling and quantification, we demonstrated that STARD3 induces cholesterol accumulation in endosomes at the expense of the plasma membrane. STARD3-mediated cholesterol routing depends both on its lipid transfer activity and its ability to create ER-endosome contacts...

Clinical features and investigations lack predictive value when diagnosing pneumonia, especially when patients are ventilated and when patients develop ventilator associated pneumonia (VAP). New tools to aid diagnosis are important to improve outcomes. This pilot study examines the potential for metabolic profiling to aid the diagnosis in critical care. In this prospective observational study ventilated patients with brain injuries or pneumonia were recruited in the intensive care unit and serum samples were collected soon after the start of ventilation...

The conjugative virulence plasmid is a key component of the Rhodococcus equi accessory genome essential for pathogenesis. There are three host-associated virulence plasmid types: the equine pVAPA and porcine pVAPB circular variants and the linear pVAPN associated with bovine (ruminant) isolates. We recently characterized the R. equi pangenome (Anastasi et al. 2016, GBE 8:3140-3148) and we report here the comparative analysis of the virulence plasmid genomes. Plasmids within each host-associated type were highly similar despite their diverse origins...
