PURPOSE: The optimal timing of spirometry during hospitalization for acute pulmonary exacerbation (PEx) in patients with cystic fibrosis (CF) is unclear. We retrospectively evaluated whether measuring spirometry earlier during hospitalization was associated with a shorter length of stay (LOS). METHODS: In this retrospective study, we analyzed data from the electronic medical record of CF patients 6 years of age and older admitted to a single center for acute PEx requiring IV antibiotic therapy between 2009 and 2016...

Introduction: Epigenome wide association studies have shown a consistent association between smoking exposure and hypomethylation in the aryl hydrocarbon receptor repressor(AHRR) gene(cg05575921). We tested the hypothesis that AHRR hypomethylation is associated with low lung function, steeper lung function decline, and respiratory symptoms in the general population.Methods:AHRR methylation extent was measured in 9113 individuals from the 1991-1994 examination of the Copenhagen City Heart Study, using bisulfite treated leucocyte DNA...

BACKGROUND: Exposure to noxious gases and particles contained in both tobacco smoking (TS) and biomass smoke (BS) are well recognized environmental risk factors for chronic obstructive pulmonary disease (COPD). COPD is characterized by an abnormal inflammatory response, both in the pulmonary and systemic compartments. The differential effects of TS, BS or their combined exposure have not been well characterized yet. This study sought to compare the lung function characteristics and systemic inflammatory response in COPD patients exposed to TS, BS or their combination...

AIMS: The effect of extravascular lung water (EVLW) and relationship to functional status as a result of acute decompensated heart failure (ADHF) are not well understood. We sought to quantify changes in clinical variables, EVLW, airway anatomy, spirometry, and diffusing capacity for carbon monoxide before and after treatment for ADHF. METHODS AND RESULTS: Fifteen patients were recruited within 24 h of hospital admission. Spirometry, diffusing capacity for carbon monoxide, and surrogates of EVLW by computed tomography were measured and were then repeated within 24 h of discharge...

OBJECTIVE: We retrospectively investigated the possibility that the 6-min walk test (6MWT) could predict surgical outcomes in lung cancer patients with decreased predicted postoperative (ppo) lung function. METHODS: Patients were enrolled based on their preoperative spirometry: <60% of the ppo forced expiratory volume in 1 s (FEV1.0) or < 60% of the ppo lung carbon monoxide diffusion capacity (DLco). Morbidity, oxygen inhalation required > 10 days, home oxygen therapy (HOT) requirement, unexpected readmission within 90 days, and 90-day mortality were included as surgical outcomes...

Background: The impact of airway obstruction of nonsmoking women caused by their husband's smoking is unclear, despite the association between environmental tobacco smoke (ETS) exposure at home and obstructive pulmonary diseases among nonsmoking women. The aim of this study was to provide evidence that ETS exposure from the husband at home has a more significant influence on the airway obstruction of nonsmoking women than other housemates. Participants and methods: Nonsmoking women aged 40 years or older were recruited from the health checkup during May 2015-December 2016, Japan...

BACKGROUND: Flavonoids exert anti-inflammatory properties and modulate oxidative stress in vitro, suggesting a protective effect on lung function, but epidemiological studies examining this association are scarce. METHODS: A stratified random sample was drawn from the GA²LEN screening survey, in which 55,000 adults aged 15 to 75 answered a questionnaire on respiratory symptoms. Post-bronchodilator spirometry was obtained from 2850 subjects. Forced vital capacity (FVC), the ratio between the forced exhaled volume in 1 second (FEV₁) and FVC (FEV₁/FVC), FVC below lower limit of normal (FVC < LLN), and FEV₁/FVC < LLN were calculated...

Bariatric surgery improves glycemic control in obese patients with diabetes type 2. Dual antiplatelet therapy can be maintained beyond 12 months after a myocardial infarction. Levothyroxine is not beneficial among patients ≥ 65 years that have subclinical hypothyroidism. Prophylactic anticoagulation in lower limb immobilisation should be reserved only for patients with a high risk of thromboembolism. A diagnosis of asthma should be initially confirmed by a spirometry if clinically suspected. A proton pump inhibitor is indicated for patients ≥ 65 years that are treated with aspirin...

BACKGROUND: Epidemiological evidence suggests the existence of a direct link between allergic rhinitis (AR) and asthma. Several studies also support the presence of small-airway dysfunction (SAD) in non-asthmatic children with AR. However, it remains unknown whether SAD can predict the progression of AR to asthma. Our objective was to explore the existence of SAD in non-asthmatic children with AR and to assessed its ability to predict the development of asthma. METHODS: Seventy-three 6-year-old children with intermittent moderate-severe AR but without asthma symptoms/medication within the last two years, underwent spirometry and measurement of respiratory resistance (Rrs) and reactance (Xrs) before and after bronchodilation (BD) (300mcg salbutamol)...

BACKGROUND: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 classification separates the spirometric 1-4 staging from the ABCD groups defined by symptoms and exacerbations. Little is known about how this new classification predicts mortality in patients with chronic obstructive pulmonary disease (COPD). We aimed to establish the predictive ability of the GOLD 2017 classification, compared with earlier classifications, for all-cause and respiratory mortality, both when using its main ABCD groups and when further subdividing according to spirometric 1-4 staging...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a non-specific inflammation, which involves the airways, lung parenchyma and pulmonary vessels. The inflammation causes the activation of inflammatory cells and the release of various inflammatory mediators such as interleukin-1 beta, interleukin-6 and tumor necrosis factor alpha (TNF-a). The present study was designed to assess the serum cytokines [Interleukin-1β (IL-1β), Interleukin-6 (IL-6), Tumor necrosis factor-α (TNF-α)] levels in chronic obstructive pulmonary disease (COPD) patients and they were correlated with severity of disease by spirometric measurements...

BACKGROUND: The prevalence of chronic obstructive pulmonary disease (COPD) in smokers enrolled as "healthy" controls in studies is 10-50%. The COPD status of ideal smoker populations for lung cancer case-control studies should be checked via spirometry; however, this is often not feasible, because no medical indications exist for asymptomatic smokers to undergo spirometry prior to study enrollment. Therefore, there is an unmet need for robust, cost effective assays for identifying undiagnosed lung disease among asymptomatic smokers...

Alongside imaging techniques, pulmonary function testing helps in the diagnosis of underlying disorders such as asthma and chronic obstructive pulmonary disease (COPD) or fibrosing lung disease. However, disease severity grading is also important, as well as disease follow-up under therapy. The value of spirometry as a first-line diagnostic test, whole-body plethysmography in advanced diagnostics, the measurement of transfer factor, as well as blood gas analysis are outlined. The importance of spiroergometry, echocardiography, and right-heart catheterization, particularly in the functional assessment of pulmonary vascular disorders, is described...
