Effects of Air Pollution-Related Heavy Metals on the Viability and Inflammatory Responses of Human Airway Epithelial Cells
Various metals produced from human activity are ubiquitously detected in ambient air. The metals may lead to induction and/or exacerbation of respiratory diseases, but the significant metals and factors contributing to such diseases have not been identified. To compare the effects of each metal and different oxidation states of metals on human airway, we examined the viability and production of interleukin (IL)-6 and IL-8 using BEAS-2B cell line, derived from human airway epithelial cells. Airway epithelial cells were exposed to Mn2+, V4+, V5+, Cr3+, Cr6+, Zn2+, Ni2+, and Pb2+ at a concentration of 0.5, 5, 50, or 500 μm...

Comment on ‘Comparative analysis of the isovolume calibration method for non-invasive respiratory
monitoring techniques based on area transduction versus circumference transduction using the
connected cylinders model’ (2011 Physiol. Meas. 32 1265–74)
An analysis introduced by the authors in 2011 examining the robustness of the isovolume method for the calibration of the respiratory inductive plethysmograph based on the connected cylinders particular model of Konno and Mead’s generalized two-compartment model of respiration is extended. It is demonstrated that extending this to a more physically realistic geometrical model, termed the connected prismatic elliptical segments model, does not enhance the earlier analysis, and that the analysis can easily be proven to cover all area-based transduction sensors, irrespective of the actual geometry of the compartments....

Optoelectronic plethysmography to evaluate the effect of posture on breathing kinematics in spinal cord injury: a cross sectional study.
CONCLUSIONS: Optoelectronic plethysmography measurements showed that even if in supine position there is an improvement in respiratory functional parameters, the respiratory kinematics of the chest wall is disadvantaged. CLINICAL REHABILITATION IMPACT: Our study suggest that the use of abdominal binders could reproduce in sitting position the positive effect of supine position on diaphragm, that could work at a more favorable point of its length tension curve.

Sendai virus recombinant vaccine expressing a secreted, unconstrained respiratory syncytial virus fusion protein protects against RSV in cotton rats
The respiratory syncytial virus (RSV) is responsible for as many as 199000 annual deaths worldwide. Currently, there is no standard treatment for RSV disease and no vaccine. Sendai virus (SeV) is an attractive pediatric vaccine candidate because it elicits robust and long-lasting virus-specific B cell and T cell activities in systemic and mucosal tissues. The virus serves as a gene delivery system as well as a Jennerian vaccine against its close cousin, human parainfluenza virus type 1. Here we describe the testing of a recombinant SeV (SeVRSV-Fs) that expresses an unconstrained, secreted RSV-F protein as a vaccine against...

Pulmonary Complications of Cardiopulmonary Bypass
Pulmonary complications after use of extracorporeal circulation are common and range from transient hypoxemia with altered gas exchange to Acute Respiratory Distress Syndrome (ARDS), with variable severity. Similar to other end organ dysfunction after cardiac surgery with extracorporeal circulation, pulmonary complications are attributed to the inflammatory response, ischemia-reperfusion injury and reactive oxygen species liberated as a result of cardiopulmonary bypass. Several factors common in cardiac surgery with extracorporeal circulation may worsen the risk for pulmonary complications including atelectasis, transfusio...

A cluster randomised trial of cloth masks compared with medical masks in healthcare workers
Conclusions This study is the first RCT of cloth masks, and the results caution against the use of cloth masks. This is an important finding to inform occupational health and safety. Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection. Further research is needed to inform the widespread use of cloth masks globally. However, as a precautionary measure, cloth masks should not be recommended for HCWs, particularly in high-risk situations, and guidelines need to be updated.

Failed needle decompression of bilateral spontaneous tension pneumothorax
This case report presents a young male admitted with primary bilateral spontaneous tension pneumothorax and severe respiratory distress. This is an extremely rare condition. The patient was on the verge of hypoxic cardiac arrest and the attempted needle thoracocentesis was unsuccessful. Needle thoracocentesis in the midclavicular line of the second intercostal space is widely used and recommended as first‐line treatment of tension pneumothorax. Reviewing the literature, the procedure is not based on solid evidence. It has high failure rates and potentially serious complications. Alternatives to this approach are perhaps ...

Regulation of B-Cell-Activating Factor Expression on the Basophil Membrane of Allergic Patients
Conclusions: Basophils from allergic and healthy subjects constitutively express membrane BAFF, which is not upregulated by IgE or specific allergens but by TLR-2 ligands (LTA-SA and β-1,3-glucan). Aspergillus fumigatus stimulation was able to upregulate BAFF expression on the basophils of sensitized asthmatic patients, but not via IgE-dependent mechanisms, since results did not differ between the patient and control groups. These findings suggest that basophils may contribute to the polyclonal production of IgE commonly observed in patients with SAFS and ABPA.Int Arch Allergy Immunol 2015;166:208-212 (Source: Internation...

Huge Respiratory Epithelial Adenomatoid Hamartoma Originating from the Inferior Nasal Turbinate: A Case Report
We report a case of a 22-year-old male patient with 7-year history of nasal obstruction and headache resulting from a huge left-sided nasal lesion. Computed tomography, magnetic resonance and biopsy were performed to make a provisional diagnosis of REAH originating from the left-sided inferior turbinate. The definitive diagnosis of REAH was made by histopathological examination of the removed mass. We also discuss the origin and differential diagnosis of these rare lesions.

Accuracy of CO 2 monitoring via nasal cannulas and oral bite blocks during sedation for esophagogastroduodenoscopy
Abstract Esophagogastroduodenoscopy procedures are typically performed under conscious sedation. Drug-induced respiratory depression is a major cause of serious adverse effects during sedation. Capnographic monitoring of respiratory activity improves patient safety during procedural sedation. This bench study compares the performance of the nasal cannulas and oral bite blocks used to monitor exhaled CO2 during sedation. We used a spontaneously breathing mechanical lung to evaluated four CO2 sampling nasal cannulas and three CO2 sampling bite blocks. We placed pneumatic resistors in the mouth of the manikin to ...

Muscle imaging data in late-onset Pompe disease reveal a correlation between the pre-existing degree of lipomatous muscle alterations and the efficacy of long-term enzyme replacement therapy
Conclusions The results demonstrate that fatty muscle degeneration can occur before clinical manifestation of muscle weakness and suggest that mildly affected muscles may respond better to ERT treatment than severely involved muscles. If these findings can be validated by further studies, it should be discussed if muscle alterations detected by muscle MRI may be an objective sign of disease manifestation justifying an early start of ERT in clinically asymptomatic patients in order to improve the long-term outcome.

Association between respiratory infections in early life and later asthma is independent of virus type
Lower respiratory tract infections in the first years of life are associated with later asthma, and this observation has led to a focus on the potential causal role of specific respiratory viruses, such as rhinoviruses and respiratory syncytial virus, in asthma development. However, many respiratory viruses and bacteria trigger similar respiratory symptoms and it is possible that the important risk factors for asthma are the underlying susceptibility to infection and the exaggerated reaction to such triggers rather than the particular triggering agent.

The Plant Derivative Compound A Inhibits the Production of Corticosteroid-resistant Chemokines by Airway Smooth Muscle Cells.
Abstract Preclinical models of human conditions including asthma showed the therapeutic potential of compound A (CpdA), a dissociated glucocorticoid (GC) receptor (GRα) ligand. Whether CpdA inhibits GC resistance, a central feature of severe asthma, has not been addressed. We investigated whether CpdA modulates cytokine-induced GC resistance in human airway smooth muscle (ASM) cells. Healthy and asthmatic ASM cells were treated with TNFα/IFNγ for 24 hr in the presence or absence of CpdA. ELISA and qPCR assays were used to assess the effect of CpdA on chemokine expression. Activation of GRα by CpdA was assessed ...

Sensitization Can Influence Mechanisms of Organophosphorus Pesticide-Induced Airway Hyperreactivity.
Abstract We previously demonstrated that antigen sensitization increases vulnerability to airway hyperreactivity induced by the organophosphorus pesticide (OP) parathion. Sensitization also changes the mechanism of parathion-induced airway hyperreactivity to one that is dependent on interleukin-5 (IL5). To determine whether this effect can be generalized to other OPs, and to other classes of pesticides, we measured airway responsiveness to vagal stimulation or intravenous acetylcholine in non-sensitized and ovalbumin-sensitized guinea pigs 24 h after a single subcutaneous injection of the OPs diazinon or chlorpyrif...

The Whitening of Brown Fat and Its Implications for Weight Management in Obesity
Abstract Systemic inflammation resulting from dysfunction of white adipose tissue (WAT) accelerates the pathologies of diabetes and cardiovascular diseases. In contrast to WAT, brown adipose tissue (BAT) is abundant in mitochondria that produce heat by uncoupling respiratory chain process of ATP synthesis. Besides BAT’s role in thermogenesis, accumulating evidence has shown that it is involved in regulating systemic metabolism. Studies have analyzed the “browning” processes of WAT as a means to combat obesity, whereas few studies have focused on the impact and molecular mechanisms that contribute to obesity-...
