This study aimed to evaluate the content that is available on COPD-related Facebook Groups, as well as the communication (self-disclosures, social support) and engagement (agreement, emotional reaction) strategies used by members to facilitate these resources. Two researchers independently searched the “Groups” category using the terms “COPD”, “emphysema”, and “chronic bronchitis”. Twenty-six closed (n = 23) and public (n = 3) COPD Facebook Groups were identified with 87,082 total members. The vast majority of Group members belonged to closed (...

AbstractObjectivesThe aim of this study was to assess the effect of hybrid iterative reconstruction and post processing on emphysema quantification in low-dose CT scans of COPD patients using pulmonary function tests (PFT) as a reference.MethodsCT scans of 23 COPD patients diagnosed with GOLD I or higher were reconstructed with iDose4 level 1 to 7 in IntelliSpace Portal (ISP) 6 and 7. ISP7 was used with and without specific denoising filter for COPD. The extent of emphysema was measured as percentage of lung voxels with attenuation

Smoke-measuring smart shirts, breath sound analyzing algorithms, and smart inhalers pave the way of pulmonology and respiratory care into the future. As the number of patients suffering from asthma, COPD, or lung cancer due to rising air pollution and steady smoker-levels will unfortunately not decrease any time soon, we looked around what technology can do to help both patients and caregivers. The results are breathtaking. Attacks of breathlessness are too common The diseases which pulmonologists and respiratory care specialists attempt to fight are among the most common conditions in the modern world – and t...

COPD and obstructive sleep apnoea (OSA) are highly prevalent and different clinical COPD phenotypes that influence the likelihood of comorbid OSA. The increased lung volumes and low body mass index (BMI) associated with the predominant emphysema phenotype protects against OSA whereas the peripheral oedema and higher BMI often associated with the predominant chronic bronchitis phenotype promote OSA. The diagnosis of OSA in COPD patients requires clinical awareness and screening questionnaires which may help identify patients for overnight study. Management of OSA-COPD overlap patients differs from COPD alone and the surviva...

CONCLUSIONS: Mice model induced by passive smoking is the classic animal model of emphysema. Pathomorphological indicators are the most important parameters for evaluating the establishment of the animal model of emphysema. PMID: 31567388 [PubMed - as supplied by publisher]

Ozone exposure causes irritation, airway hyperreactivity (AHR), inflammation of the airways, and destruction of alveoli (emphysema), the gas exchange area of the lung in human and mice. This review focuses on the acute disruption of the respiratory epithelial barrier in mice. A single high dose ozone exposure (1 ppm for 1 h) causes first a break of the bronchiolar epithelium within 2 h with leak of serum proteins in the broncho-alveolar space, disruption of epithelial tight junctions and cell death, which is followed at 6 h by ROS activation, AHR, myeloid cell recruitment, and remodeling. High ROS levels activate a novel P...

Authors: Radovanovic D, Contoli M, Marco FD, Sotgiu G, Pelaia G, Braido F, Corsico AG, Micheletto C, Rogliani P, Scichilone N, Saderi L, Santus P, Solidoro P Abstract Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease. The severity grading systems proposed by the Global initiative for Chronic Obstructive Lung Disease (GOLD) have changed over time. The aim of the study was to evaluate if the different GOLD classifications can capture the complexity of the disease by investigating the distribution of lung function and clinical parameters across the GOLD classification systems. This was an observa...

This is especially important for COPD patients, but also for a variety of other disorders of the respiratory system. At the workshop "Luftschlösser", held once more at Wiesbaden, Germany in February 2019 the many and important interactions of the lungs and the heart as well as the therapeutic implications were discussed. Based on pathophysiology, the psycho-social consequences of dyspnea, t...
