Depression is associated with poor control of symptoms in asthma and rhinitis: A population-based study
2019
Abstract Background Although many studies have highlighted the link between asthma/rhinitis and depression, it is still unclear which characteristics of these diseases are associated with the risk of depression. We aimed to explore the relationship between depression and asthma or rhinitis in a representative sample of the Italian general population. Methods The data were collected in GEIRD, an Italian multicenter, population-based, multicase-control study. 2227 participants (age 21–86 years, female 50%) underwent standardized interviews, skin prick and lung function tests, and were divided into cases of current asthma (n = 528), rhinitis without asthma (n = 972), and controls (n = 727). Tw…
Gender Differences in Health‐Related Quality of Life Among Patients with Asthma
2004
This study has a twofold objective: 1) to explore to what extent suffering from asthma affects the HRQL of men and women differently at several stages of disease severity and 2) to analyze whether the informed poorer HRQL of asthmatic women is related to their higher scores on instruments measuring emotionally disordered symptoms. One hundred fifty-one outpatient asthmatics (84 women and 67 men) completed the Spanish versions of the Asthma Quality of Life questionnaire (AQL), as well as anxiety and depression inventories. A full history, physical examination, and pulmonary function test were performed on all subjects. Patients were classified into one of four asthma severity categories foll…
Quantitative analysis of emphysema in 3D using MDCT: Influence of different reconstruction algorithms
2008
Abstract Purpose The aim of the study was to compare the influence of different reconstruction algorithms on quantitative emphysema analysis in patients with severe emphysema. Material and methods Twenty-five patients suffering from severe emphysema were included in the study. All patients underwent inspiratory MDCT (Aquilion-16, slice thickness 1/0.8 mm). The raw data were reconstructed using six different algorithms: bone kernel with beam hardening correction (BHC), soft tissue kernel with BHC; standard soft tissue kernel, smooth soft tissue kernel (internal reference standard), standard lung kernel, and high-convolution kernel. The only difference between image data sets was the algorith…
Pulmonary emphysema in cystic fibrosis detected by densitometry on chest multidetector computed tomography.
2013
BackgroundHistopathological studies on lung specimens from patients with cystic fibrosis (CF) and recent results from a mouse model indicate that emphysema may contribute to CF lung disease. However, little is known about the relevance of emphysema in patients with CF. In the present study, we used computationally generated density masks based on multidetector computed tomography (MDCT) of the chest for non-invasive characterization and quantification of emphysema in CF.MethodsVolumetric MDCT scans were acquired in parallel to pulmonary function testing in 41 patients with CF (median age 20.1 years; range 7-66 years) and 21 non-CF controls (median age 30.4 years; range 4-68 years), and subj…
Differences of airway dimensions between patients with and without bronchiolitis obliterans syndrome after lung transplantation-Computer-assisted qua…
2016
Abstract Background The aim of our retrospective study was to determine whether a dedicated software for assessment of airway morphology can detect differences in airway dimensions between patients with and without bronchiolitis obliterans syndrome (BOS), regarded as the clinical correlate of chronic lung allograft rejection. Methods 12 patients with and 14 patients without diagnosis of BOS were enrolled in the study. Evaluation of bronchial wall area percentage (WA%) and bronchial wall thickness (WT) in all follow-up CT scans was performed using a semiautomatic airway assessment tool. We assessed temporal changes (ΔWA%, ΔWT) and compared these morphological parameters with forced expirator…
Parathyroid Hormone as a Novel Biomarker for Chronic Obstructive Pulmonary Disease: Korean National Health and Nutrition Examination Survey
2015
Objective To understand and predict chronic obstructive pulmonary disease (COPD), a biomarker that reflects disease severity is needed. Research Design and Methods Data from 10269 adults aged over 40 years of age were retrieved from the Korea National Health and Nutrition Examination Survey (KNHANES), and 1302 patients met the criteria for COPD. The association between values of vitamin D and parathyroid hormone (PTH), and COPD severity including lung function and quality of life, were analyzed. Results In COPD patients, lung function was inversely related to PTH values (P = 0.02 for FVC [% predicted]; P < 0.001 for FEV1 [% predicted]); however, the association of lung function with vitamin…
Pulmonary embolism location is associated with the co-existence of the deep venous thrombosis.
2019
Multiple studies have shown that in approximately half of individuals with pulmonary embolism (PE), the deep venous thrombosis (DVT) is not evident at the moment of PE diagnosis. The underlying factors and the origin of PE in these patients are not completely understood: missed DVT, embolization of DVT in its entirety, or de-novo PE being possible explanations. The aim of this study was to evaluate the differences in PE patient with or without co-existing DVT. Sixty-three consecutive PE patients were included. Whole leg bilateral Doppler compression ultrasound was performed to all patients. The PE location and extension, C-reactive protein, platelet count, hemostatic markers FV, FVIII, FXII…
Kyphoscoliosis ventilatory insufficiency: noninvasive management outcomes.
2000
Objective: To determine the effects on symptoms, pulmonary function, sleep, and other clinical variables of treating kyphoscoliosis-associated chronic alveolar hypoventilation with nocturnal nasal ventilation. Design: Sixteen patients with kyphoscoliosis were treated with nocturnal nasal ventilation delivered by volume-cycled (seven patients) and pressure-cycled (nine patients) ventilators. Dyspnea, morning headaches, fatigue, hypersomnolence, and perceived sleep quality were assessed. Results: All pretreatment symptoms improved significantly with nasal ventilation. Likewise, Pao 2 (mm Hg), Pao 2 /Fio 2 , Paco 2 (mm Hg), pH, and forced vital capacity (in milliliters and as a percentage of p…
Asthma, allergies and respiratory symptoms in different activity groups of swimmers exercising in swimming halls
2021
Abstract Background Respiratory symptoms are common in competitive swimmers. However, among these and in swimmers at other activity levels the swimming distance, the total spent time in swimming halls and their medical background varies. Our objectives were, first, to assess their medical histories and the associations with respiratory symptoms among swimmers in different activity groups and then second, to study the pulmonary function findings and related medications in competitive swimmers who exercise in swimming hall environments the most. Methods First, 1118 participants consisting of 133 competitive-, 734 fitness- and 251 occasional swimmers answered questionnaires concerning their me…
Successful treatment of a patient with ARDS after pneumonectomy using high-frequency oscillatory ventilation.
1999
High frequency oscillatory ventilation (HFOV) was used in a patient who developed the acute respiratory distress syndrome 5 days following a right pneumonectomy for bronchogenic carcinoma. When conventional pressure-controlled ventilation failed to maintain adequate oxygenation, HFOV dramatically improved oxygenation within the first few hours of therapy. Pulmonary function and gas exchange recovered during a 10-day period of HFOV. No negative side effects were observed. Early use of HFOV may be a beneficial ventilation strategy for adults with acute pulmonary failure, even in the postoperative period after lung resection.
