Dendritic polyglycerols (dPG), particularly dendritic polyglycerol sulfates (dPGS), have been intensively studied due to their intrinsic anti-inflammatory activity. As related to brain pathologies involving neuroinflammation, the current study examined if dPG and dPGS can (i) regulate neuroglial activation, and (ii) normalize the morphology and function of excitatory postsynaptic dendritic spines adversely affected by the neurotoxic 42 amino acid amyloid-β (Aβ42 ) peptide of Alzheimer disease (AD). The exact role of neuroglia, such as microglia and astrocytes, remains controversial especially their positive and negative impact on inflammatory processes in AD...

Brain and spinal cord injury may lead to permanent disability and death because it is still not possible to regenerate neurons over long distances and accurately reconnect them with an appropriate target. Here a procedure is described to rapidly initiate, elongate, and precisely connect new functional neuronal circuits over long distances. The extension rates achieved reach over 1.2 mm/h, 30-60 times faster than the in vivo rates of the fastest growing axons from the peripheral nervous system (0.02 to 0.04 mm/h)28 and 10 times faster than previously reported for the same neuronal type at an earlier stage of development4 ...

INTRODUCTION: Patients with chronic obstructive pulmonary disease often experience exacerbations. These events are important as they are a major cause of morbidity and mortality. Recently, it has been increasingly recognized that patients may experience symptoms suggestive of an exacerbation but do not seek treatment, which are referred to as unreported or untreated exacerbations. Symptom diaries used in clinical trials have the benefit of identifying both treated and untreated exacerbation events...

BACKGROUND: C-reactive protein (CRP) measurement has proven valuable for detecting exacerbations, but its usefulness in predicting etiology remains controversial. Likewise, its potential value as a marker of severity, which is well established in patients with pneumonia, remains unproven in chronic obstructive pulmonary disease (COPD) exacerbations. METHODS: A cohort study of 118 patients with severe COPD and acute infectious exacerbations were included and followed up over 1 year...

We studied activation of hemostatic reactions together with mechanisms of systemic inflammation and genetic factors responsible for thrombogenic risk in 65 patients suffering exacerbation of chronic obstructive pulmonary disease with 2 or 3 positive criteria proposed by N.Anthonisen at al. (1987). The levels of indicators of systemic inflammation, such as C-reactive protein and tumour necrosis factor-alpha, increased concurrently with those of homocysteine, endothelin-1, Willebrand factor plasminogen activator inhibitor type 1, and thrombin-antithrombin complex (marker of thrombinemia)...

OBJECTIVE: We reported association of haplotypes formed by IL-1b (IL1B)-511C/T (rs16944) and a variable number of tandem repeats (rs2234663) in intron 3 of IL-1 receptor antagonist (IL1RN) with rate of lung function decline in smoking-induced COPD. The aim of current study was to further investigate this association. METHODS: We genotyped an additional 19 polymorphisms in IL1 cluster (including IL1A, IL1B and IL1RN) in non-Hispanic whites who had the fastest (n = 268) and the slowest (n = 292) decline of FEV1% predicted in the same study...

BACKGROUND: Acute exacerbations represent a significant burden for patients with moderate-to-severe chronic obstructive pulmonary disease. Each exacerbation episode is frequently associated with a lengthy recovery and impaired quality of life. Prognostic factors for outpatients that may predict poor outcome after treatment with antibiotics recommended in the guidelines, are not fully understood. We aimed to identify pretherapy factors predictive of clinical failure in elderly (≥60 years old) outpatients with acute Anthonisen type 1 exacerbations...

BACKGROUND: In acute exacerbation of chronic obstructive pulmonary disease (AECOPD) antibiotic overprescribing leads to antimicrobial resistance and underprescribing may cause poor patient outcomes. OBJECTIVE: This study aimed to evaluate changes in over- and underprescribing of antibiotics after two interventions to optimize antibiotic prescribing in AECOPD in Spain. METHODS: In 2008 and 2009, general practitioners (GPs) registered patients in a 3-week period before and after interventions...

Resistance to cephalosporins in Haemophilus influenzae is usually caused by characteristic alterations in penicillin-binding protein 3 (PBP3), encoded by the ftsI gene. Resistance to extended-spectrum cephalosporins is associated with high-level PBP3-mediated resistance (high-rPBP3), defined by the second stage S385T substitution in addition to a first stage substitution (R517H or N526K). The third stage L389F substitution is present in some high-rPBP3 strains. High-rPBP3 H. influenzae are considered rare outside Japan and Korea...

COPD Exacerbation RiskSESSION TYPE: Original Investigation SlidePRESENTED ON: Wednesday, October 29, 2014 at 02:45 PM - 04:15 PMPURPOSE: Prior data suggested that among Anthonisen criteria only an increase in sputum purulence was a predictor of clinical failure among mild to moderate COPD outpatients who did not receive antibiotics. In addition the use of a point-of-care C-reactive protein (CRP) test (cutoff > 40 mg/L) significantly increased the predictive accuracy of failure. However, limited data are available regarding the translation of these findings among hospitalized acutely exacerbated COPD (AECOPD) patients who did not receive antibiotics...

In the last decade, numerous papers have discussed what has been called the indiscriminate use of intermittent positive pressure breathing therapy (IPPB) for the treatment of obstructive airways disease (Curtis et al., 1968; Loke and Anthonisen, 1974; Cheney et al., 1976; Baker, 1974; Murray, 1974; Barach and Segal, 1975; Sheldon and Gold, 1976; Dolovich et al., 1977). These papers have all failed to show any advantage of positive pressure breathing therapy, either in the acute or chronic stages of obstructive airways disease...

BACKGROUND: Bacteria and viruses are major causes of chronic obstructive pulmonary disease (COPD) exacerbations. Molecular components of these pathogens are recognized by pattern-recognition receptors (PRRs) expressed by various cells in the airway, which leads to initiation of inflammatory processes. Expression levels of PRRs in airway inflammatory cells are expected to affect susceptibility to COPD exacerbation. AIMS: This prospective observational study was conducted to detect any association between exacerbation and PRR expression...

BACKGROUND: Beta-lactam resistance in Haemophilus influenzae due to ftsI mutations causing altered penicillin-binding protein 3 (PBP3) is increasing worldwide. Low-level resistant isolates with the N526K substitution (group II low-rPBP3) predominate in most geographical regions, while high-level resistant isolates with the additional S385T substitution (group III high-rPBP3) are common in Japan and South Korea.Knowledge about the molecular epidemiology of rPBP3 strains is limited. We combined multilocus sequence typing (MLST) and ftsI/PBP3 typing to study the emergence and spread of rPBP3 in nontypeable H...

Abstract Bacterial infection is a major cause of acute exacerbations of chronic obstructive pulmonary disease (AECOPD), which are associated with significantly increased airway and systemic inflammation. However, the relationship among bacteriology, the resolution of inflammation and clinical outcomes is largely unknown. In this study, we recruited consecutive patients hospitalized for AECOPD with purulent sputum. We measured the airway and systemic inflammation levels, the COPD assessment test (CAT) score and adverse outcomes between patients with and without potentially pathogenic microorganisms (PPM)...

In March 2012, a second outbreak of Cryptosporidium parvum affected children following a stay at a holiday farm in Norway; the first outbreak occurred in 2009. We studied a cohort of 145 schoolchildren who had visited the farm, of which 40 (28%) were cases. Cryptosporidium oocysts were detected in faecal samples from humans, goat kids and lambs. Molecular studies revealed C. parvum subtype IIa A19G1R1 in all samples including human samples from the 2009 outbreak. A dose-response relationship was found between the number of optional sessions with animals and illness, increasing from two sessions [risk ratio (RR) 2·7, 95% confidence interval (CI) 0·6-11·5] to six sessions (RR 8·0, 95% CI 1·7-37·7)...
