MicroRNAs (miRNAs) regulate post-transcriptional gene expression and may be exported from cells via exosomes or in partnership with RNA-binding proteins. MiRNAs in body fluids can act in a hormone-like manner and play important roles in disease initiation and progression. Hence, miRNAs are promising candidates as biomarkers. To identify serum miRNA biomarkers in the equine model of asthma we investigated small RNA derived from the serum of 34 control and 37 asthmatic horses. These samples were used for next generation sequencing, novel miRNA identification and differential miRNA expression analysis...

OBJECTIVE: Incidental pulmonary findings are commonly detected at lung cancer screening chest CT. Though most of these findings are clinically insignificant, it is difficult to prospectively determine which are potentially important to clinical care. The purpose of this review is to discuss the incidental pulmonary findings commonly detected at lung cancer screening chest CT. CONCLUSION: Incidental pulmonary findings most commonly fall into one of three categories: interstitial lung disease, emphysema, and airways disease (both small and large airways)...

BACKGROUND: There has been little investigation regarding air quality and rhinitis in the pathophysiology of upper airway disease. In this study, we assessed the impact of inhalant pollutants (particulate matter 2.5 [PM2.5 ] and black carbon [BC]) on allergic rhinitis and chronic rhinosinusitis (CRS) disease severity. METHODS: CRS patients with nasal polyps (CRSwNP) and without polyps (CRSsNP) were identified. Spatial modeling from pollutant monitoring sites was used to estimate exposures for patients meeting the inclusion criteria (total, n = 125; CRSsNP, n = 67; CRSsNP, n = 58)...

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is used extensively in cardiothoracic surgery both for hemodynamic and respiratory support. It has proven to be a valuable tool to maintain adequate oxygenation during tracheal surgery. Airway lesion may be an indication for veno-venous ECMO both in case of conservative management and in case of surgical repair. Here we report the case of a patient with a iatrogenic tracheal injury, successfully operated with the support of veno-venous extracorporeal oxygenation...

The particles in exhaled breath provide a promising matrix for the monitoring of pathological processes in the airways, and also allow exposure to exogenous compounds to be to assessed. The collection is easy to perform and is non-invasive. The aim of the present study is to assess if an exogenous compound-methadone-is distributed in the lining fluid of small airways, and to compare two methods for collecting methadone in particles in exhaled breath. Exhaled particles were collected from 13 subjects receiving methadone maintenance treatment...

Although, bronchoscopy is a relatively safe procedure, small amount of bleeding in the airway can have serious consequences. Careful consideration of the risks of diagnostic and therapeutic bronchoscopic intervention can help minimize potential complications. With increasing number of patients using antiplatelet and anticoagulation therapies, strategies for minimizing thromboembolic and operative bleeding events need to be included in the risk and benefit analyses. Growing evidence suggests that aspirin is safe and does not increase bleeding during bronchoscopy...

Interstitial lung diseases (ILDs) form one of the most fascinating fields in pulmonary medicine. They also pose one of the greatest challenges for accurate diagnosis and proper treatment. Even within the recommended and warranted multidisciplinary approach, differentiating between one disease and another may lead to frustration, especially when proper lung tissue is not available for adequate pathological review. A surgical lung biopsy (SLB) might render enough tissue for histopathology, but this could come at the expense of high morbidity and even mortality, as in the case of usual interstitial pneumonia (UIP)...

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide, with increasing prevalence, in particular in the elderly. COPD is characterised by abnormal tissue repair resulting in (small) airways disease and emphysema. There is accumulating evidence that ageing hallmarks are prominent features of COPD. These ageing hallmarks have been described in different subsets of COPD patients, in different lung compartments and also in a variety of cell types, and thus might contribute to different COPD phenotypes...

PURPOSE OR REVIEW: Population-based studies have shown a significant heterogeneity in patients with chronic obstructive pulmonary disease (COPD), regarding both the attainment of maximal lung function and the subsequent decline over time. This review will highlight recent advances in the understanding of lung function trajectory in COPD, focusing on factors that influence peak adult lung function, markers of accelerated lung function decline and pharmacologic interventions in early phases of the disease...

BACKGROUND: Smoking is as prevalent in asthmatics as in the general population. Asthmatic smokers benefit less from inhaled corticosteroids (ICS) than non-smoking asthmatics, possibly due to more smoking-induced small airways disease. Thus targeting small airways may be important in treating asthmatic (ex-)smokers. We hypothesized that extrafine particle ICS improve small airways function more than non-extrafine particle ICS in asthmatic (ex-)smokers. METHODS: We performed an open-label, randomized, three-way cross-over study comparing extrafine beclomethasone (HFA-QVAR) to non-extrafine beclomethasone (HFA-Clenil) and fluticasone (HFA-Flixotide) in 22 smokers and 21 ex-smokers with asthma (?5 packyears)...

Importance: Nasal continuous positive airway pressure (NCPAP) as a primary respiratory therapy in meconium aspiration syndrome (MAS) has not been studied extensively. Nasal continuous positive airway pressure, when applied in newborns with MAS, may resolve atelectasis by sufficiently expanding partially obstructed small airways and stabilizing the collapsing terminal airways to enhance oxygen exchange. Objective: To compare NCPAP vs standard care in neonates with moderate to severe respiratory failure due to MAS in reducing the need for invasive ventilation...

The cytokine interleukin (IL)-17C is highly expressed in epithelial tissues and involved in innate immune responses; however, the regulation of IL-17C expression in the airways remains poorly understood. Here, we show that IL-1β strongly induces both IL-17C mRNA and protein expression in primary normal human bronchial epithelial cells. Conversely, IL-13 significantly reduced the IL-1β-induced IL-17C expression. Attenuation of the nuclear factor (NF)-κB-signaling pathway using an NF-κB-subunit p65-specific small-interfering RNA (siRNA), reduced IL-1β-induced IL-17C expression, demonstrating the importance of NF-κB signaling in IL-17C regulation...

Study objectives: Patients with comorbid posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) manifest low adherence to continuous positive airway pressure (CPAP) due to fixed, pressure-induced expiratory pressure intolerance (EPI), a subjective symptom and objective sign aggravated by anxiety sensitivity and somatosensory amplification. As advanced PAP therapy modes (ie, auto-bilevel PAP [ABPAP] or adaptive servo-ventilation [ASV]) may address these side effects, we hypothesized such treatment would be associated with decreased expiratory intolerance and increased adherence in posttraumatic stress patients with co-occurring OSA...

Adult survivors of very preterm birth (≤32 weeks gestational age) without (PRE) and with bronchopulmonary dysplasia (BPD) have obstructive lung disease as evidenced by reduced expiratory airflow at rest and have significant mechanical ventilatory constraints during exercise. Airflow obstruction, under any condition, could be due to several factors including small airways. PRE and/or BPD could have smaller airways than their counterparts born at full-term (CON) due to a greater degree of dysanaptic airway development during the pre- and/or post-natal period...

OBJECTIVES: Lung cancer is the leading cause of cancer related deaths worldwide and mutation activating KRAS is one of the most frequent mutations found in lung adenocarcinoma. Identifying regulators of KRAS may aid in the development of therapies to treat this disease. The mitogen-induced gene 6, MIG-6, is a small adaptor protein modulating signaling in cells to regulate the growth and differentiation in multiple tissues. Here, we investigated the role of Mig-6 in regulating adenocarcinoma progression in the lungs of genetically engineered mice with activation of Kras...
