Delirium detection using EEG: what and how to measure?
Conclusions:In a homogenous population of non-sedated cardiothoracic surgery patients, we observed that relative delta power from an eyes-closed EEG recording with only two electrodes in a frontal-parietal derivation can distinguish post-cardiothoracic surgery patients with delirium from those without. Background: Despite its frequency and impact, delirium is poorly recognized in postoperative- and critically ill patients. EEG (electroencephalography) is highly sensitive to delirium, but as currently used, it is not diagnostic. To develop an EEG-based tool for delirium detection with a limited number of electrodes, we ...

Prolonged Clonal Spreading and Dynamic Changes in Antimicrobial Resistance of Escherichia coli ST68 Among Patients Who Stayed in a Respiratory Care Ward.
Abstract We collected a total of 83 bacteremic isolates of Escherichia coli with reduced susceptibility or resistance to third generation cephalosporins (TGCs) from 2007 to 2009. Isolates were genotyped by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). The PFGE patterns revealed 2 highly correlated clusters (cluster E: 9 isolates; cluster G: 22 isolates) associated with this prolonged clonal spreading. Compared with cluster E isolates, cluster G isolates had a significantly higher rate of harboring aac(6')-Ib-cr (p < 0.05), and most of these were isolated during a later year than ...

Early Postnatal Respiratory Viral Infection Alters Hippocampal Neurogenesis, Cell Fate, and Neuron Morphology in the Neonatal Piglet.
Abstract Respiratory viral infections are common during the neonatal period in humans, but little is known about how early-life infection impacts brain development. The current study used a neonatal piglet model as piglets have a gyrencephalic brain with growth and development similar to human infants. Piglets were inoculated with porcine reproductive and respiratory syndrome virus (PRRSV) to evaluate how chronic neuroinflammation affects hippocampal neurogenesis and neuron morphology. Piglets in the neurogenesis study received one bromodeoxyuridine injection on postnatal day (PD) 7 and then were inoculated with PR...

Assessment of the mode of action for hexavalent chromium-induced lung cancer following inhalation exposures.
Abstract Inhalation of hexavalent chromium [Cr(VI)] is associated with increased lung cancer risk among workers in several industries, most notably chromate production workers exposed to high concentrations of Cr(VI) (≥100μg/m(3)), for which clear exposure-response relationships and respiratory irritation and tissue damage have been reported. Data from this industry are used to assess lung cancer risk associated with environmental and current occupational exposures, occurring at concentrations that are significantly lower (approximately a million-fold). There is considerable uncertainty in the low dose extrapola...

Non cystic fibrosis bronchiectasis: A longitudinal retrospective observational cohort study of Pseudomonas persistence and resistance
The hallmark of non-cystic fibrosis bronchiectasis is recurrent bronchial infection, yet there are significant gaps in our understanding of pathogen persistence, resistance and exacerbation frequencies. Pseudomonas aeruginosa is a key pathogen thought to be a marker of disease severity and progression, yet little is known if the infection risk is seen in those with milder disease or if there is any potential for eradication. These data are important in determining risk stratification and follow up. (Source: Respiratory Medicine CME)

Hypermutation in Burkholderia cepacia complex is mediated by DNA mismatch repair inactivation and is highly prevalent in cystic fibrosis chronic respiratory infection.
In conclusion, in the present study we demonstrate for the first time that, MRS-deficient Bcc species mutators are highly prevalent and positively selected in CF chronic lung infections. Hypermutation therefore, might be playing a key role in increasing bacterial adaptability to the CF-airway environment, facilitating the persistence of chronic lung infections.

Nasal and ocular amyloidosis in a 15-year-old horse
Localized nasal, conjunctival and corneal amyloidosis was diagnosed in a 15-year-old pony with nasal and conjunctival masses and severe dyspnoea. Multiple swellings had been evident in the nostrils for at least two years and had gradually increased in size before presentation due to dyspnoea and exercise intolerance. Surgical debulking of the masses was performed and histological examination revealed large amounts of extracellular, hyaline, eosinophilic, Congo red positive material in the lamina propria of the nasal mucosa. A tentative diagnosis of localized nasal amyloidosis was made. The treatment relieved the clinical s...

Purified deoxynivalenol or feed restriction reduces mortality in rainbow trout, Oncorhynchus mykiss (Walbaum), with experimental bacterial coldwater disease but biologically relevant concentrations of deoxynivalenol do not impair the growth of Flavobacterium psychrophilum
Abstract Diets containing deoxynivalenol (DON) were fed to rainbow trout Oncorhynchus mykiss (Walbaum) for 4 weeks followed by experimental infection (intraperitoneal) with Flavobacterium psychrophilum (4.1 × 106 colony‐forming units [CFU] mL−1). Mortality of rainbow trout fed either 6.4 mg kg−1 DON or trout pair‐fed the control diet was significantly reduced (P < 0.05) in comparison with trout fed the control diet to apparent satiation (<0.1 mg kg−1 DON). In a second experiment, trout were fed one of three experimental diets; a control diet, a diet produced with corn naturally contaminated with ...

Complete coding regions of the prototypes enterovirus B93 and C95: Phylogenetic analyses of the P1 and P3 regions of EV‐B and EV‐C strains
Complete coding regions were sequenced for two new enterovirus genomes: EV‐B93 previously identified by VP1 sequencing, derived from a child with acute flaccid paralysis in the Democratic Republic of Congo; and EV‐C95 from a French soldier with acute gastroenteritis in Djibouti. The EV‐B93 P1 had more than 30% nucleotide divergence from other EV‐B types, with highest similarity to E‐15 and EV‐B80. The P1 nucleotide sequence of EV‐C95 was most similar, 71%, to CV‐A21. Complete coding regions for the new enteroviruses were compared with those of 135 EV‐B and 176 EV‐C strains representing all types availab...

Sequential infusion of donor‐derived dendritic cells with donor lymphocyte infusion for relapsed hematologic cancers after allogeneic hematopoietic stem cell transplantation
Donor lymphocyte infusion (DLI) is often given to induce a graft‐versus‐leukemia (GVL) effect after allogeneic hematopoietic stem cell transplantation (HSCT). However, efficacy of DLI is limited in most hematologic cancers. As antigen presenting cells, dendritic cells (DC) bolster immune responses. We conducted a Phase I trial testing the coinfusion of DC followed by DLI. DC were generated by culturing peripheral blood mononuclear cells from HLA matched‐related donors in GM‐CSF and IL‐4 for 7 days, followed by TNF‐α for 3 days. DC were administered intravenously on 3 dose levels (5 × 106; 1 × 107; 5 × 107 c...

Evidence for multiple sensory circuits in the brain arising from the respiratory system: an anterograde viral tract tracing study in rodents.
Abstract Complex sensations accompany the activation of sensory neurons within the respiratory system, yet little is known about the organization of sensory pathways in the brain that mediate these sensations. In the present study, we employ anterograde viral neuroanatomical tract tracing with isogenic self-reporting recombinants of HSV-1 strain H129 to map the higher brain regions in receipt of vagal sensory neurons arising from the trachea versus the lungs, and single-cell PCR to characterize the phenotype of sensory neurons arising from these two divisions of the respiratory tree. The results suggest that the up...

The Role of Stepdown Beds in Hospital Care.
Abstract Stepdown beds provide an intermediate level of care for patients with requirements somewhere between that of the general ward and the intensive care unit. Models of care include incorporation of step-down beds into intensive care units, stand-alone units, or incorporation of beds into standard wards. Stepdown beds may be used to provide a higher level of care for patients deteriorating on a ward ("step-up"), a lower level of care for patients transitioning out of intensive care ("step-down") or a lateral transfer of care from a recovery room for post-operative patients. These units are one possible strateg...

IL-17 in Severe Asthma: Where Do We Stand?
Abstract Asthma is a major chronic disease ranging from mild to severe refractory disease and is classified into various clinical phenotypes. Severe asthma is difficult to treat and frequently requires high doses of systemic steroids. In some cases, severe asthma even responds poorly to steroids. Several studies have suggested a central role of IL-17 (also called IL-17A) in severe asthma. Indeed, high levels of IL-17 are found in induced sputum and bronchial biopsies obtained from severe asthmatics. The recent identification of a steroid-insensitive pathogenic TH17 pathway is therefore of major interest. In additio...

Physiological responses of a rodent to helox reveal constancy of evaporative water loss under perturbing environmental conditions.
We present here evidence, based on the first measurements of evaporative water loss for a small mammal in helox, that mammals may have a previously unappreciated ability to maintain acute constancy of total evaporative water loss under perturbing environmental conditions. Thermoregulatory responses of ash-grey mice (Pseudomys albocinereus) to helox were as expected, with changes in metabolic rate, conductance and respiratory ventilation consistent with maintaining constancy of body temperature under conditions of enhanced heat loss. However, evaporative water loss did not increase in helox. This is despite our confirmation...

Abstract Milk fat globule membrane (MFGM) comprises carbohydrates, membrane-specific proteins, glycoproteins, phospholipids, and sphingolipids. We evaluated the effects of MFGM consumption over a 12-week period on endurance capacity and energy metabolism in BALB/c mice. Long-term MFGM intake combined with regular exercise improved endurance capacity, as evidenced by swimming time until fatigue, in a dose-dependent manner. The effect of dietary MFGM plus exercise was accompanied by higher oxygen consumption and lower respiratory quotient, as determined by indirect calorimetry. MFGM intake combined with exercise incr...
