Bhajan Singh, Azadeh Yadollahi, Owen Lyons, Hisham Alshaer, TDouglas Bradley
Prolonged sitting may promote leg fluid retention that redistributes to the neck during sleep and contributes to snoring. This could be attenuated by calf activity while sitting. In 16 healthy non-obese subjects we measured leg fluid volume (LFV) below the knees using bioelectrical impedance while sitting for 4hours, snoring using a portable BresoDx™ device, and Mallampati grade. Using a double cross-over study design, subjects were randomized to one of two arms and crossed-over one week later: control arm - no calf exercise while sitting; intervention arm - calf contraction against a pedal resistance while sitting...

In the last two decades, an enormous expansion of evidence has been produced in upper airway research. When writing the first EPOS document in 2005 only 5 RCT per year were performed in the area of CRS, in 2007 this changed to 25 per year and it became even higher in the recent years. Randomized Controlled Trials (RCTs) are the "gold standard" for evaluating treatment outcomes providing information on treatments "efficacy". To make life easier for clinicians, systematic reviews and meta-analysis further condense the available evidence...

BACKGROUND: Asthma is a complex lung disease resulting from the interplay of genetic and environmental factors. To understand the molecular changes that occur during the development of allergic asthma without genetic and environmental confounders, an experimental model of allergic asthma in mice was used. Our goals were to (1) identify changes at the small molecule level due to allergen exposure, (2) determine perturbed pathways due to disease, and (3) determine whether small molecule changes correlate with lung function...

Lulu Ma, Xuerong Yu
Arthrogryposis multiplex congenita (AMC) is a rare disorder characterized by non-progressive, multiple contractures. In addition to affected extremities, patients may also present microstomia, decreased temporomandibular joint mobility. Although the etiology of AMC is unclear, any factor that decreases fetal movement is responsible for AMC. Thus, accurate diagnosis and classification are crucial to the appropriate treatment of AMC. The development of ultrasound technology has enabled prenatal diagnosis. Very early treatment is favorable, and multidisciplinary treatment is necessary to improve the function of AMC patients...

Adenoids play a key role in both respiratory and ear infection in children. It has also been shown that adenoidectomy improves these symptoms in this population. The main goal of the present study was to evaluate adenoid bacterial colonization and document a possible relation with infectious respiratory disease. A prospective observational study was designed to evaluate the proposed hypothesis in a paediatric population submitted to adenoidectomy by either infectious or non-infectious indications and compare these two cohorts...

Drug-Induced Sedation Endoscopy (DISE) consists of the direct observation of the upper airways during sedative-induced sleep, allowing the identification of the sites of pharyngeal collapse, which is the main pathological event in Obstructive Sleep Apnea (OSA). The Authors have compared Target Controlled Infusion (TCI) sedation endoscopy (TCI-DISE) technique to conventional DISE (CDISE), performed by a manual bolus injection of sedative agent, to recreate accurately and safely snoring and apnea patterns comparable to natural sleep...

The use of high-flow nasal cannula (HFNC) therapy as respiratory support for preterm infants has increased rapidly worldwide. The evidence available for the use of HFNC is as an alternative to nasal continuous positive airway pressure (CPAP) and in particular to prevent postextubation failure. We report a case of tension pneumocephalus in a preterm infant as a complication during HFNC ventilation. Significant neurological impairment was detected and support was eventually withdrawn. Few cases of pneumocephalus as a complication of positive airway pressure have been reported in the neonatal period, and they all have been related to CPAP...

Cystic fibrosis-related diabetes (CFRD) is the most common co-morbidity associated with cystic fibrosis (CF) and correlates with increased rates of lung function decline. Since glucose is a nutrient present in the airways of patients with bacterial airway infections and since insulin controls glucose metabolism, the effect of insulin on CF airway epithelia was investigated to determine the role of insulin receptors and glucose transport in regulating glucose availability in the airway. The response to insulin by human airway epithelial cells was characterized by qPCR, immunoblot, immunofluorescence, and glucose uptake assays...

Visceral organs of vertebrates show left-right (L-R) asymmetry with regard to their position and morphology. Cilia play essential role in generating L-R asymmetry. A number of genes required for L-R asymmetry have now been identified in vertebrates, including human, many of which contribute to the formation and motility of cilia. In the mouse embryo, breaking of L-R symmetry occurs in the ventral node, where two types of cilia (motile and immotile) are present. Motile cilia are located at the central region of the node, and generate a leftward fluid flow...

Stable suspensions of metal oxide nanoparticles (Me-NPs) obtained by laser ablation of 99.99% pure copper, zinc or lead under a layer of deionized water were used separately, in three binary combinations and a triple combination in two independent experiments on rats. In one of the experiments the rats were instilled with Me-NPs intratracheally (i.t.) (for performing a broncho-alveolar lavage in 24hrs to estimate the cytological and biochemical indices of the response of the lower airways), while in the other, Me-NPs were repeatedly injected intraperitoneally (i...

AZD5423 is a novel, inhaled, selective glucocorticoid receptor modulator (SGRM), which in an allergen challenge model in asthmatics improved lung function and airway hyper-reactivity. In the current trial, AZD5423 was for the first time tested in patients with chronic obstructive pulmonary disease (COPD). In this double-blind, randomised and parallel group study, we examined airway and systemic effects of two doses of AZD5423, inhaled via Turbuhaler for 12 weeks, in 353 symptomatic COPD patients (average pre-bronchodilator forced expiratory volume in one second (FEV1) at screening was 50-52% of predicted normal)...

Surgery patients in Japan undergo routine spirometry testing prior to general anesthesia. The use of a flow sensor during general anesthesia has recently become common. However, it is not certain whether the information derived from flow-volume curves is being adequately used for mechanical ventilation management during general anesthesia. So far, there have been no attempts to calculate airway resistance using flow-volume curves. Therefore, we performed a prospective, observational study to investigate the relationship between pre-anesthetic and intra-anesthetic airway resistance in patients scheduled for surgery under general anesthesia...

This special article presents potentially important trends and issues affecting the field of obstetric anesthesia drawn from publications in 2015. Both maternal mortality and morbidity in the United States have increased in recent years because, in part, of the changing demographics of the childbearing population. Pregnant women are older and have more pre-existing conditions and complex medical histories. Cardiovascular and noncardiovascular medical diseases now account for half of maternal deaths in the United States...

PURPOSE OF REVIEW: Current imaging techniques (X-ray, computed tomography scan, ultrasound) have limitations in the identification and quantification of pulmonary diseases, in particular, on highly detailed level. The purpose of this review is to provide an overview of the current knowledge of innovative light- and laser-based imaging techniques that might fill this gap. RECENT FINDINGS: Optical coherence tomography (OCT) and confocal laser endomicroscopy (CLE) are high-resolution imaging techniques, which, combined with bronchoscopy, provide 'near histology' detailed imaging of the airway wall, lung parenchyma, mediastinal lymph nodes, and pulmonary vasculature...

PURPOSE OF REVIEW: Exacerbations of bronchiectasis have a major impact on quality of life, healthcare costs, and long-term risk of complications. Preventing exacerbations is one of the major goals of treatment. Bronchiectasis is increasingly recognized and the impact of bronchiectasis exacerbations on daily clinical practice is also increasing. RECENT FINDINGS: Preventing bronchiectasis exacerbations are dependent on appropriate risk assessment, identifying the patients at highest risk to rationally target preventive therapies...

BACKGROUND: Mild asthmatics who smoke cigarettes may develop unstable disease and neutrophilic infiltration of the airways, features more usually associated with severe asthmatic disease. The mechanisms giving rise to this response remain unclear. OBJECTIVE: To address the hypothesis that smoking increases bronchial mucosal production of IL-17A which acts on bronchial epithelial cells directly and in concert with other environmental stimuli to induce the production of IL-6 and neutrophil chemotaxins...
