BACKGROUND: Chronic obstructive pulmonary disease (COPD) may cause changes in the shape of the thoracic cage by increasing lung volume and hyperinflation. This study investigated changes in thoracic cage dimensions and related factors in patients with COPD. METHODS: We enrolled 85 patients with COPD (76 males, 9 females; mean age, 70.6±7.1 years) and 30 normal controls. Thoracic cage dimensions were measured using chest computed tomography at levels 3, 6, and 9 of the thoracic spine...

BACKGROUND: Pulmonary hyperinflation in chronic obstructive pulmonary disease (COPD) is associated with reduced biventricular end-diastolic volumes and increased morbidity and mortality. The combination of a long-acting β agonist (LABA) and a muscarinic antagonist (LAMA) is more effective in reducing hyperinflation than LABA-inhaled corticosteroid combination therapy but whether dual bronchodilation improves cardiac function is unknown. METHODS: We did a double-blind, randomised, two-period crossover, placebo-controlled, single-centre study (CLAIM) at the Fraunhofer Institute of Toxicology and Experimental Medicine (Hannover, Germany), a specialty clinic...

OBJECTIVE: to assess the effect of lung hyperinflation (LHI) in patients with chronic obstructive pulmonary disease (COPD) on longterm outcomes of percutaneous coronary intervention (PCI). MATERIALS AND METHODS: Patients with COPD who suffered stable ischemic heart disease and underwent PCI (n=135) were included in a prospective cohort study. LHI was found in 60 patients, while 75 patients had no LHI. Evaluation included comparing the frequency of major adverse cardiac events (MACE) (cardiac death, myocardial infarcпункtion [MI], stroke, repeat revascularization) and Kaplan-Mayer curves between groups of patients with and without LHI...

BACKGROUND AND OBJECTIVE: Lung hyperinflation and reduced bronchodilation to deep inspiration (DI) are features of chronic obstructive pulmonary disease (COPD). Hyperinflation might impair the ability of a DI to stretch airway smooth muscle (ASM), as the bronchi operate at a stiff region of the pressure-volume curve. METHODS: Bronchial segments from pig lungs were mounted in an organ bath and equilibrated at either 5 cm H2 O (control) or 20 cm H2 O (hyperinflated) transmural pressure (Ptm )...

Endoscopic lung volume reduction is a minimally invasive procedure performed to reduce the space occupied by the emphysemas' lobes. This procedure has been demonstrated to be beneficial for patients with advanced chronic obstructive pulmonary disease and severe hyperinflation. The use of endobronchial valves is increasing, as well as the number of reports of adverse events. The most common complications after the procedure are a pneumothorax, bleeding, infections, the need for valve removal, and valve expulsion...

INTRODUCTION: Manual hyperinflation (MH), a maneuver applied in mechanically ventilated patients to facilitate secretion removal, has large variation in its performance. Effectiveness of MH is usually evaluated by its capacity to generate an expiratory flow bias. The aim of this study was to compare the effects of MH-and its resulting flow bias-applied according to clinical practice versus according to expert recommendation on mucus movement in a lung model simulating a mechanically ventilated patient...

Background: Lung hyperinflation and exercise intolerance are hallmarks of chronic obstructive pulmonary disease (COPD). However, their relationship remains uncertain. A combined analysis of two placebo-controlled, randomized studies examined the effects of the long-acting muscarinic antagonist umeclidinium (UMEC) and long-acting β2-agonist vilanterol (VI) separately and in combination on static hyperinflation, exercise endurance time (EET), and their relationship in patients with COPD...

RATIONALE: Vascular Ehlers-Danlos syndrome (vEDS) is a rare autosomal dominant inherited collagen disorder caused by defects or deficiency of pro-alpha 1 chain of type III procollagen encoded by COL3A1. vEDS is characterized not only by soft tissue manifestations including hyperextensibility of skin and joint hypermobility but also by early mortality due to rupture of arteries or vital organs. Although pulmonary complications are not common, vEDS cases complicated by pneumothorax, hemothorax, or intrapulmonary hematoma have been reported...

Lung volume reduction surgery (LVRS) offers improvement in lung function, quality of life and even survival in well selected patients with severe emphysema. Patients with all types of emphysema morphology can profit from LVRS when certain selection criteria are present. Hyperinflation plays a key role in qualifying for the procedure. Candidate selection should be performed at high volume centers with a multidisciplinary emphysema board. Qualified thoracic surgeons together with pulmonologists and radiologists identify the suitable patient considering emphysema morphology with its target areas for resection, lung function parameters and cardiac comorbidities...

Bronchodilator therapy is central to the management of chronic obstructive pulmonary disease and are recommended as the preferred treatment by the Global Obstructive Lung Disease Initiative (GOLD). Long acting anti-muscarinics (LAMA) and long acting β₂ agonists (LABA) are both more effective than regular short-acting drugs but many patients remain symptomatic despite monotherapy with these drugs. Combination therapy with LAMA and LABA increases the therapeutic benefit while minimizing dose-dependent side effects of long-acting bronchodilator therapy...

BACKGROUND: High frequency percussive ventilation (HFPV) combines diffusive (high frequency mini-bursts) and convective ventilation patterns. Benefits include enhanced oxygenation and hemodynamics, and alveolar recruitment, while providing hypothetic lung-protective ventilation. No study has investigated HFPV-induced changes in lung aeration in patients with early acute respiratory distress syndrome (ARDS). METHODS: Eight patients with early non-focal ARDS were enrolled and five swine with early non-focal ARDS were studied in prospective computed tomography (CT) scan and animal studies, in a university-hospital tertiary ICU and an animal laboratory...
