ConclusionBy applying [11C]DASB and PET/CT, semiquantitative measures of SERT availability are demonstrated in the lung vasculature of patients with COPD and/or PH. COPD patients who developed PH show increased pulmonary [11C]DASB uptake compared to COPD patients without PH indicating an implication of pulmonary SERT in the development of PH in COPD patients.

Authors: D'Anna SE, Maniscalco M, Cappello F, Carone M, Motta A, Balbi B, Ricciardolo FM, Caramori G, Di Stefano A Abstract In COPD patients, bacterial and viral infections play a relevant role in worsening lung function and, therefore, favor disease progression. The inflammatory response to lung infections may become a specific indication of the bacterial and viral infections. We here review data on the bacterial-viral infections and related airways and lung parenchyma inflammation in stable and exacerbated COPD, focusing our attention on the prevalent molecular pathways in these different clinical conditions. The...

CONCLUSIONS: Disadvantages by individual and neighborhood-level SES each partly explain disparities in respiratory outcomes between black individuals and whites. Strategies to narrow the gap in SES disadvantages may help to reduce race-related health disparities in COPD; however, further work is needed to identify additional risk factors contributing to persistent disparities.

Abstract S100 calcium-binding protein A9 (S100A9), is elevated in plasma and bronchoalveolar lavage fluid (BALF) of COPD patients and aging enhances S100A9 expression in several tissues. Currently, the direct impact of S100A9-mediated signaling on lung function and within the aging lung is unknown. Here, we observed that elevated S100A9 levels in human BALF correlated with age. Elevated lung levels of S100A9 were higher in older mice compared to young animals and coincided with pulmonary function changes. Both acute and chronic exposure to cigarette smoke enhanced S100A9 levels in age-matched mice. To examine the ...

Abstract COPD is an inflammatory lung disease, which is often exacerbated with microbial infections resulting in worsening of respiratory symptoms. Gallic acid (GA), a naturally occurring phenolic compound is known to possess anti-oxidant/anti-inflammatory activity. We have recently reported that GA protects against the elastase (ET) induced lung inflammation and emphysema and the present work was designed to investigate the beneficial effects of Gallic acid against ET + Lipopolysachharide (LPS) induced COPD exacerbation like condition in mice model. Our data showed that i.t. administration of LPS at...

CONCLUSION: Probable ACO is associated with WTC exposures. Further study of ACO is needed to understand the development of this and other environmentally or occupationally-related airway diseases, and how to prevent these in disasters like 9/11. PMID: 32930623 [PubMed - as supplied by publisher]

Lung cancer is a frequent comorbidity of chronic obstructive pulmonary disease (COPD). However, the local risk of developing lung cancer related to regional emphysema distribution and clinical outcome has not ...

Abstract Computed tomography (CT) is a valuable tool in the workup of patients under investigation for pulmonary hypertension (PH) and may be the first test to suggest the diagnosis. CT parenchymal lung changes can help to differentiate the aetiology of PH. CT can demonstrate interstitial lung disease, emphysema associated with chronic obstructive pulmonary disease, features of left heart failure (including interstitial oedema), and changes secondary to miscellaneous conditions such as sarcoidosis. CT also demonstrates parenchymal changes secondary to chronic thromboembolic disease and venous diseases such as pulm...
