Pulmonary function testing in HTLV-I and HTLV-II infected humans: a cohort study

BMC Pulmonary Medicine, 2003
Background HTLV-I infection has been linked to lung pathology and HTLV-II has been associated with an increased incidence of pneumonia and acute bronchitis. However it is unknown whether HTLV-I or -II infection alters pulmonary function.

Acute effects of combined exercise and oscillatory positive expiratory pressure therapy on sputum properties and lung diffusing capacity in cystic fibrosis: a randomized, controlled, crossover trial

BMC Pulmonary Medicine, 2018
Background Regular airway clearance by chest physiotherapy and/or exercise is critical to lung health in cystic fibrosis (CF). Combination of cycling exercise and chest physiotherapy using the Flutter® device on sputum properties has not yet been ...

Lung volumes identify an at-risk group in persons with prolonged secondhand tobacco smoke exposure but without overt airflow obstruction. [PDF]

, 2018
IntroductionExposure to secondhand smoke (SHS) is associated with occult obstructive lung disease as evident by abnormal airflow indices representing small airway disease despite having preserved spirometry (normal forced expiratory volume in 1 s-to ...

New Spirometry Indices for Detecting Mild Airflow Obstruction. [PDF]

, 2018
The diagnosis of chronic obstructive pulmonary disease (COPD) relies on demonstration of airflow obstruction. Traditional spirometric indices miss a number of subjects with respiratory symptoms or structural lung disease on imaging.

Relationship between diffusion capacity and small airway abnormality in COPDGene. [PDF]

, 2019
Impaired single breath carbon monoxide diffusing capacity (DLCO) is associated with emphysema. Small airways disease (SAD) may be a precursor lesion to emphysema, but the relationship between SAD and DLCO is undescribed. We hypothesized that in mild COPD,

Recommendations for the use of endoscopic lung volume reduction in South Africa: Role in the treatment of emphysema [PDF]

, 2015
Emphysema is a very common cause of morbidity and mortality in South Africa (SA). Therapeutic options in severe emphysema are limited. Endoscopic lung volume reduction (ELVR) is increasingly being used internationally for the treatment of advanced ...

The effect of aging and cardiorespiratory fitness on the lung diffusing capacity response to exercise in healthy humans [PDF]

, 2017
Aging is associated with deterioration in the structure and function of the pulmonary circulation. We characterized the lung diffusing capacity for carbon monoxide (DLCO), alveolar-capillary membrane conductance (Dm(CO)), and pulmonary-capillary blood ...

Modeling of Red Blood Cells in Capillary Flow Using Fluid–Structure Interaction and Gas Diffusion

Cells, 2022
Red blood cell (RBC) distribution, RBC shape, and flow rate have all been shown to have an effect on the pulmonary diffusing capacity. Through this study, a gas diffusion model and the immersed finite element method were used to simulate the gas ...

Impact of Respiratory Developmental Stage on Sensitivity to Late Effects of Radiation in Pediatric Cancer Survivors

Advances in Radiation Oncology, 2020
Purpose: Pulmonary dysfunction is a prevalent and potentially debilitating late effect of pediatric cancer treatment. We postulated that age, as a surrogate for respiratory developmental status, might be associated with vulnerability to pulmonary injury.
