Filter by:Chronic obstructive pulmonary disease and periodontitis are chronic inflammatory diseases. The study aims to determine if the genetic polymorphism of SERPINA1 gene in patients with COPD serve as a risk factor for developing periodontitis.
The purpose of this study is to assess whether administration of a bolus dose of MgSO4 (magnesium sulfate) plus standard therapy is superior to standard therapy alone for the management of Acute Exacerbations of Chronic Pulmonary Obstructive Disease (AECOPD) in the emergency department. The investigators hypothesize that MgSO4 causes faster recovery of the bronchospasm, and a reduction of the dead space, translating to the following clinical outcomes : less hospitalisation, lower length of stay (LOS), better composite outcome of hospitalisation + LOS + readmission for AECOPD.
Decreased exercise capacity and quality of life, increased dyspnea and fatigue perception and hypoxemia during exercise is seen in patients with interstitial lung disease. Impaired ventilatory response, increased lung compliance, ventilation-perfusion mismatching and inadequate peripheral circulation causes decreased exercise capacity. Another important factor that induce decreased exercise capacity is peripheral muscle weakness. In literature, there is no study investigated effects of neuromuscular electrical stimulation on functional exercise capacity, respiratory and peripheral muscle strength, pulmonary functions, physical activity level, dyspnea and fatigue perception in patients with interstitial lung disease.
Lung protection should start in the delivery room where, from the first breaths, the preterm infant can be helped to clear the lung fluid and to recruit alveolar spaces and establish the functional residual capacity (FRC). Sustained lung inflation (SLI) applied at birth in the delivery room has been demonstrated to lead to clearance of lung fluid and achievement of a precocious functional residual capacity (FRC) both in animal and human studies. SLI associated to an adequate positive end expiratory pressure (PEEP) may help the efficacy of the respiratory effort in lung of preterm infants at risk for respiratory distress syndrome (RDS) and reduce need of mechanical ventilation (MV). Further studies are required to evaluate the clinical utility of this maneuver. The ability to monitor what happens to the lungs while applying different recruitment maneuvers in preterm infants would allow the definition of a procedure that allows optimal assistance to improve the FRC. One promising approach is provided by the forced oscillation technique (FOT). During forced oscillations, a small amplitude sinusoidal pressure stimulus is applied to the airway opening and the mechanical response of the respiratory system is studied by means of the total respiratory input impedance (Zin). Zin is a complex number that can be expressed as real part, called resistance (Rrs), and imaginary part, called reactance (Xrs). Particularly, it has been recently shown that Xrs measured at 5 Hz is very sensible to changes in the mechanics of lung periphery and provides accurate information about lung volume recruitment and derecruitment. The main purpose of this work is to apply FOT to the assessment of lung function in newborns submitted to SLI at birth. The investigators hypothesized that the application in the delivery room of the SLI in the preterm infant is effective in achieving a greater FRC and therefore a greater value of Xrs compared to a control group not treated with the SLI.
Chronic Obstructive Pulmonary Disease (COPD) is a respiratory disease starting point characterized by multiple systemic effects as cognitive dysfunction. This one seems to have an impact in activity daily living, considered mainly as a cognitive-motor dual task situations. Yet to date, no study has specifically focused in the cognitive-motor performance in patients with COPD or on the effects during a rehabilitation program. The main objective of this work was to evaluate the impact of cognitive dysfunction in COPD, comparing performance between COPD patients and healthy subjects in a single and dual task cognitive-motor situation. The secondary objective was to assess the impact of a rehabilitation program on these performances.
The inhaled Iloprost, approved for pulmonary hypertension, caused increase in oxygenation, and increase exercise tolerance in ARDS or chronic obstructive pulmonary disease. Inhaled iloprost has been researched in animal study, but not yet in human during one-lung ventilation. The investigators will enroll patients who diagnosed moderate to severe chronic obstructive pulmonary disease, preoperative pulse oximetry (SpO2) of below 95% at room air or PaO2 /FiO2 ratio< 150 mmHg after initiating one-lung ventilation. The primary outcome is pulmonary oxygenation expressed by PaO2 /FiO2 ratio. And secondary outcome is assessment of cardiac function including Tei-index during nebulizing iloprost. The investigators hypothesized inhaled iloprost will improve oxygenation and decrease the FiO2 in chronic obstructive pulmonary disease during one-lung ventilation.
The differential diagnosis of asthma and COPD is sometimes difficult. Recently, an overlap syndrome has been defined based on the concurrence of asthma and COPD characteristics. These characteristics are based on expert opinions and have never been investigated nor validated prospectively. The investigators assume that the management strategy, the symptom burden and disease progression will differ between asthma, COPD and ACOS. Therefore, the study wants to establish baseline criteria for an appropriate disease definition and evaluate the potential impact on treatment and symptom control.
The purpose of this study is to demonstrate that the efficacy of the combination product QVA149 is similar to the efficacy of the combination product umeclidinium/vilanterol on a pre-specified endpoint of FEV1 AUC0-24h while maintaining an acceptable safety profile.

The primary objective of this research project is to describe the characteristics, diagnosis, management, and outcomes of patients with Interstitial Lung Disease (ILD) who received care at the Veteran's Administration Veterans Integrated Service Network (VISN) 6 Mid-Atlantic Health Care Network (VISN6) (includes North Carolina, Virginia and West Virginia) for up to 5 years.
