Personalized Goal for Dyspnea and Clinical Response in Advanced Cancer Patients
2018
Abstract Background The clinical response after comprehensive symptom management is difficult to determine in terms of a clinically important difference. Moreover, therapies should try to reach the threshold perceived by the individual patient for the determination of a favorable response to a treatment. Measures The Edmonton Symptom Assessment Score (ESAS) was measured at admission (T0), and seven days after starting palliative care (T7). Patient Global Impression and Goal Response after one week of palliative care and its relation with the Personalized Dyspnea Goal were measured at T7. Intervention Patients admitted to palliative care units underwent a comprehensive symptom assessment by …
Clinical presentation of patients with suspected obstructive sleep apnea and self-reported physician-diagnosed asthma in the ESADA cohort.
2018
Obstructive sleep apnea (OSA) and asthma are often associated and several studies suggest a bidirectional relationship between asthma and OSA. This study analyzed the characteristics of patients with suspected OSA from the European Sleep Apnea Database according to presence/absence of physician-diagnosed asthma. Cross-sectional data in 16,236 patients (29.1% female) referred for suspected OSA were analyzed according to occurrence of physician-diagnosed asthma for anthropometrics, OSA severity and sleepiness. Sleep structure was assessed in patients studied by polysomnography (i.e. 48% of the sample). The prevalence of physician-diagnosed asthma in the entire cohort was 4.8% (7.9% in women, …
Obstructive sleep apnoea in adult patients post-tonsillectomy
2021
Background: The impact of removing the upper airway lymphoid tissue and in particular, tonsillectomy, in adults with OSA has not been demonstrated in large populations. Aims: To compare the severity of OSA and the prevalence of cardiovascular, metabolic and respiratory co-morbidities between patients with OSA who had undergone previous tonsillectomy and those who had not. Methods: The 19,711 participants in this study came from the European sleep apnea database (ESADA) which comprises data from unselected adult patients aged 18–80 years with a history of symptoms suggestive of OSA referred to sleep centers throughout Europe. Results: There were no differences between the two groups in terms…
Sputum metalloproteinase-9/tissue inhibitor of metalloproteinase-1 ratio correlates with airflow obstruction in asthma and chronic bronchitis
1998
Asthma and chronic bronchitis are inflammatory diseases with extracellular matrix (ECM) remodeling and collagen deposition. Collagen homeostasis is controlled by metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). We evaluated MMP and TIMP balance in induced sputum of 10 control, 31 untreated asthmatic, and 16 chronic bronchitic subjects. We first performed zymographic analysis to identify the profile of MMPs. Zymography revealed a similar MMPs profile in all populations studied and that MMP-9 was the major enzyme released. We then measured, using enzyme immunoassay, the concentrations of MMP-9 and of its inhibitor TIMP-1 and evaluated whether airflow limitation m…
Increased Levels of Elastase and α1-Antitrypsin in Sputum of Asthmatic Patients
1998
Asthma and chronic bronchitis are inflammatory diseases associated with remodeling of the extracellular matrix (ECM). Elastin, a major component of the ECM in the airways, has been previously found to be disrupted in asthma and chronic bronchitis. This study was aimed at evaluating whether elastin disruption might be associated with an imbalance between elastase (active and total) and alpha1-proteinase inhibitor (alpha1-PI), the main inhibitor of elastase. We measured elastase and alpha1-PI in induced sputum obtained from 16 control subjects, 10 healthy smokers, 19 asthmatic patients, and 10 chronic bronchitis patients. We also assessed the possible origin of elastase, evaluating its levels…
GINA 2019: a fundamental change in asthma management
2019
GINA no longer recommends treating adults/adolescents with asthma with short-acting bronchodilators alone. Instead, they should receive symptom-driven (in mild asthma) or a daily corticosteroid-containing inhaler, to reduce risk of severe exacerbations.http://bit.ly/310LLzE
Airway cells after swimming outdoors or in the sea in nonasthmatic athletes
2003
BONSIGNORE, M. R., G. MORICI, L. RICCOBONO, M. PROFITA, A. BONANNO, A. PATERNO, R. DI GIORGI, L. CHIMENTI, P. ABATE, F. MIRABELLA, A. M. VIGNOLA, and G. BONSIGNORE. Airway Cells after Swimming Outdoors or in the Sea in Nonasthmatic Athletes. Med. Sci. Sports Exerc., Vol. 35, No. 7, pp. 1146–1152, 2003. Marathon runners and elite swimmers showed increased inflammatory cells in the airways at baseline. Although airway neutrophils increase further after a marathon race, the airway response to swimming is unknown. The aim of this study was to assess the effects of swimming on airway cells. To avoid the concomitant effects of chronic exposure to chlorine, the study was conducted in seven nonasth…
Pleural Mesothelial Cells Express Both BLT2 and PPARα and Mount an Integrated Response to Pleural Leukotriene B4
2008
Abstract Leukotriene B4 (LTB4) plays a crucial role in the recruitment of neutrophils into the pleural space. We identified for the first time the mechanisms by which LTB4 interacts with mesothelial cells and recruits neutrophils in the pleural compartment. Primary pleural mesothelial cells express both the proinflammatory receptor for LTB4 BLT2, and the anti-inflammatory receptor for LTB4, PPARα. Parapneumonic pleural effusions highly increase BLT2 expression and, via BLT2 activation, increase the adhesion between mesothelial cells and neutrophils and the expression of ICAM-1 on mesothelial cells. The block of PPARα further increases both cell adhesion and ICAM-1 expression. BLT2 activatio…
The Treatment of Mild and Moderate Asthma in Adults
2020
BACKGROUND: Asthma is a chronic inflammatory airway disease that usually causes variable airway obstruction. It affects 5–10% of the German population. METHODS: This review is based on relevant publications retrieved by a selective search, as well as on national and international guidelines on the treatment of mild and moderate asthma in adults. RESULTS: The goal of treatment is to attain optimal asthma control with a minimal risk of exacerbations and mortality, loss of pulmonary function, and drug side effects. This can be achieved with a combination of pharmacotherapy and non-drug treatment including patient education, exercise, smoking cessation, and rehabilitation. Pharmacohterapy is ba…
Impact of Bimaxillary Advancement Surgery on the Upper Airway and on Obstructive Sleep Apnea Syndrome: a Meta-Analysis
2018
AbstractUpper airway changes following bimaxillary advancement surgery to treat obstructive sleep apnea syndrome remain controversial. The main objective of this systematic review and meta-analysis was to investigate the effects of bimaxillary advancement surgery on the upper airway (UA) of obstructive sleep apnea syndrome patients through examining changes three-dimensionally in vertical and supine position and through changes in oximetric variables (AHI, RDI, O2 Sat) and in the quality of life measured by the Epworth sleepiness scale (ESS). A thorough search of the PubMed, Scopus, Embase and Cochrane databases and a grey literature search (Opengrey) were conducted. No limit was placed on …
