    Metabolomics in COPD Acute Respiratory Failure Requiring Noninvasive Positive Pressure Ventilation.
    Can Respir J 2017 17;2017:9480346. Epub 2017 Dec 17.
    Critical Care and Acute Care Surgery Division, Department of Surgery, University of Minnesota, Minneapolis, MN, USA.
    We aimed to investigate whether metabolomic analysis can discriminate acute respiratory failure due to COPD exacerbation from respiratory failure due to heart failure and pneumonia. Since COPD exacerbation is often overdiagnosed, we focused on those COPD exacerbations that were severe enough to require noninvasive mechanical ventilation. We enrolled stable COPD subjects and patients with acute respiratory failure requiring noninvasive mechanical ventilation due to COPD, heart failure, and pneumonia. Read More

    The Role of Serotonin Transporter in Human Lung Development and in Neonatal Lung Disorders.
    Can Respir J 2017 20;2017:9064046. Epub 2017 Feb 20.
    Department of Pathology and Laboratory Medicine, Children's Hospital Colorado, University School of Medicine of Colorado, 13123 East 16th Avenue, P.O. Box 120, Aurora, CO 80045, USA.
    Failure of the vascular pulmonary remodeling at birth often manifests as pulmonary hypertension (PHT) and is associated with a variety of neonatal lung disorders including a uniformly fatal developmental disorder known as alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV). Serum serotonin regulation has been linked to pulmonary vascular function and disease, and serotonin transporter (SERT) is thought to be one of the key regulators in these processes. We sought to find evidence of a role that SERT plays in the neonatal respiratory adaptation process and in the pathomechanism of ACD/MPV. Read More

    Pulmonary Hypertension Associated with Idiopathic Pulmonary Fibrosis: Current and Future Perspectives.
    Can Respir J 2017 13;2017:1430350. Epub 2017 Feb 13.
    Department of Biochemistry and Molecular Biology, University of Texas Medical School at Houston, Houston, TX 77030, USA.
    Pulmonary hypertension (PH) is commonly present in patients with chronic lung diseases such as Chronic Obstructive Pulmonary Disease (COPD) or Idiopathic Pulmonary Fibrosis (IPF) where it is classified as Group III PH by the World Health Organization (WHO). PH has been identified to be present in as much as 40% of patients with COPD or IPF and it is considered as one of the principal predictors of mortality in patients with COPD or IPF. However, despite the prevalence and fatal consequences of PH in the setting of chronic lung diseases, there are limited therapies available for patients with Group III PH, with lung transplantation remaining as the most viable option.

    Division of Thoracic and Foregut Surgery, Swedish Medical Center and Cancer Institute, 1101 Madison Street, Suite 900, Seattle, WA 98104, USA.
    Octogenarians are at increased risk for complications after lung resection. With alternatives such as radiation, understanding the risks of surgery and associated survival are valuable. Data grading the severity of complications and long-term survival in this population is lacking. Read More

    Comparison of Comfort and Effectiveness of Total Face Mask and Oronasal Mask in Noninvasive Positive Pressure Ventilation in Patients with Acute Respiratory Failure: A Clinical Trial.

    Tracheal Diseases Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
    . There is a growing controversy about the use of oronasal masks (ONM) or total facemask (TFM) in noninvasive positive pressure ventilation (NPPV), so we designed a trial to compare the uses of these two masks in terms of effectiveness and comfort.. Read More

    Comparison of the Fractional Exhaled Nitric Oxide Levels in Adolescents at Three Schools Located Three Different Distances from a Large Steel Mill.
    Can Respir J 2017 6;2017:6231309. Epub 2017 Feb 6.
    Department of Pulmonology, Karabük University, Karabük, Turkey.
    Exposure to ambient metals and air pollutants in urban environments has been associated with impaired lung health and inflammation in the lungs. Fractional exhaled nitric oxide (FeNO) is a reliable marker of airway inflammation. In this study, we aimed to compare the FeNO levels of three schools that have different distances from iron and steel industry zone for assessing the effects of heavy metals and air pollution on their respiratory health.

    Aerobic exercise performed after hospital discharge for exacerbated COPD patients is already recommended to improve respiratory and skeletal muscle strength, increase tolerance to activity, and reduce the sensation of dyspnea. Previous studies have shown that anaerobic activity can clinically benefit patients hospitalized with exacerbated COPD. However, there is little information on the feasibility and safety of aerobic physical activity performed by patients with exacerbated COPD during hospitalization. Read More
