Autophagy in pulmonary macrophages mediates lung inflammatory injury via NLRP3 inflammasome activation during mechanical ventilation
The inflammatory response is a primary mechanism in the pathogenesis of ventilator-induced lung injury. Autophagy is an essential, homeostatic process by which cells break down their own components. We explored the role of autophagy in the mechanisms of mechanical ventilation-induced lung inflammatory injury. Mice were subjected to low (7 ml/kg) or high (28 ml/kg) tidal volume ventilation for 2 h. Bone marrow-derived macrophages transfected with a scrambled or autophagy-related protein 5 small interfering RNA were administered to alveolar macrophage-depleted mice via a jugular venous cannula 30 min before the start of the ...

EGFR activation suppresses respiratory virus-induced IRF1-dependent CXCL10 production
Airway epithelial cells are the primary cell type involved in respiratory viral infection. Upon infection, airway epithelium plays a critical role in host defense against viral infection by contributing to innate and adaptive immune responses. Influenza A virus, rhinovirus, and respiratory syncytial virus (RSV) represent a broad range of human viral pathogens that cause viral pneumonia and induce exacerbations of asthma and chronic obstructive pulmonary disease. These respiratory viruses induce airway epithelial production of IL-8, which involves epidermal growth factor receptor (EGFR) activation. EGFR activation involves ...

Arginase II is a target of miR-17-5p and regulates miR-17-5p expression in human pulmonary artery smooth muscle cells
Vascular remodeling and smooth muscle cell proliferation are hallmark pathogenic features of pulmonary artery hypertension. MicroRNAs, endogenously expressed small noncoding RNAs, regulate gene expression at the posttranscriptional level. It has previously been shown that miR-17 overexpression in cultured human pulmonary artery smooth muscle cell (hPASMC) resulted in increased viable cell number. Previously, we have found that arginase II promotes hypoxia-induced proliferation in hPASMC. Therefore, we hypothesized that miR-17 would be upregulated by hypoxia in hPASMC and would result in greater arginase II expression. We f...

Mitochondrial respiration and microRNA expression in right and left atrium of patients with atrial fibrillation
This study aims to investigate mitochondrial function and miR expression in the right (RA) and left atria (LA) of patients with AF and sinus rhythm (SR). Myocardial tissue from the RA and LA appendages was investigated in 37 patients with AF (n = 21) or SR (n = 16) undergoing coronary artery bypass surgery and/or heart valve surgery. Mitochondrial respiration was measured in situ after tissue permeabilization by saponin. MiR expression was assessed by miR array and real-time quantitative reverse-transcription polymerase chain reaction. Maximal mitochondrial respiratory rate was increased in both RA and LA tissue of patient...

Animal Models of Allergic Airways Disease: Where Are We and Where to Next?
Abstract In a complex inflammatory airways disease such as asthma, abnormalities in a plethora of molecular and cellular pathways ultimately culminate in characteristic impairments in respiratory function. The ability to study disease pathophysiology in the setting of a functioning immune and respiratory system therefore makes mouse models an invaluable tool in translational research. Despite the vast understanding of inflammatory airways diseases gained from mouse models to date, concern over the validity of mouse models continues to grow. Therefore the aim of this review is two‐fold; firstly, to evaluate mouse models o...

Recruitment and plasticity in diaphragm, intercostal, and abdominal muscles in unanesthetized rats
Although rats are a frequent model for studies of plasticity in respiratory motor control, the relative capacity of rat accessory respiratory muscles to express plasticity is not well known, particularly in unanesthetized animals. Here, we characterized external intercostal (T2, T4, T5, T6, T7, T8, T9 EIC) and abdominal muscle (external oblique and rectus abdominis) electromyogram (EMG) activity in unanesthetized rats via radiotelemetry during normoxia (Nx: 21% O2) and following acute intermittent hypoxia (AIH: 10 x 5-min, 10.5% O2; 5-min intervals). Diaphragm and T2–T5 EIC EMG activity, and ventilation were also ass...

Does manual therapy provide additional benefit to breathing retraining in the management of dysfunctional breathing? A randomised controlled trial.
Conclusion: Breathing retraining is currently the mainstay of treatment for patients with DB. The results of this study suggest MT provides no additional benefit in this patient group. Implications for Rehabilitation Dysfunctional breathing (DB) is associated with significant patient morbidity but often goes unrecognised, leading to prolonged investigation and significant use of health care resources. Breathing retraining remains the primary management of this condition. However, physiotherapists are also using manual therapy (MT) as an adjunctive treatment for patients with DB. However, the results of this study suggest t...

Plasticity of fimbrial genotype and serotype within populations of Bordetella pertussis: analysis by paired flow cytometry and genome sequencing.
Abstract The fimbriae of Bordetella pertussis are required for colonisation of the human respiratory tract. Two serologically distinct fimbrial subunits, Fim2 and Fim3, having been considered important vaccine components for many years, are included in the Sanofi Pasteur 5-component acellular pertussis vaccine, and the World Health Organisation recommends the inclusion of strains expressing both fimbrial serotypes in whole cell pertussis vaccines. Each of the fimbrial major subunit genes, fim2, fim3, and also fimX, has a promoter poly(C) tract upstream of its -10 box. Such monotonic DNA elements are susceptible to ...

Endotracheal intubation in the pediatric emergency department.
CONCLUSION: Intubation of children in the ED is a low-frequency, high-risk procedure. The incidence of adverse events, particularly desaturation and hypotension, is high. The incidence of difficult laryngoscopy is low. First pass success rate without desaturation or hypotension is low. Strategies to avoid desaturation and hypotension in the peri-intubation setting should be prioritized. PMID: 25039321 [PubMed - as supplied by publisher] (Source: Paediatric Anaesthesia)

Hypersensitivity Reactions to Nonsteroidal Anti-Inflammatory Drugs
Nonsteroidal anti-inflammatory drugs (NSAIDs) are the drugs most commonly involved in hypersensitivity drug reactions. Such reactions can be due to the release of inflammatory mediators in the absence of specific immunologic recognition, or immunoglobulin E (IgE)- or T-cell–selective responses. The former include upper and lower airway symptoms in patients with chronic underlying respiratory disease, the exacerbation of chronic spontaneous urticaria, and the induction of cutaneous symptoms. The latter include selective responses to a single NSAID with good tolerance to strong cyclooxygenase-1 inhibitors, with a putative ...

Barriers to the provision of smoking cessation assistance: a qualitative study among Romanian family physicians.
Conclusions:Many of the barriers described by the Romanian FPs reflected universally recognised challenges to the provision of smoking cessation advice. The context of a relatively hierarchical health-care system and limitations of time and resources exacerbated many of the problems and created new barriers that will need to be addressed if Romania is to achieve the aims of its National Programme Against Tobacco Consumption.
