Impact of extrafine formulations of inhaled corticosteroids/long-acting beta-2 agonist combinations on patient-related outcomes in asthma and COPD
2014
Nicola Scichilone,1 Alida Benfante,1 Luca Morandi,2 Federico Bellini,2 Alberto Papi21Biomedical Department of Internal and Specialist Medicine, Section of Pulmonology, University of Palermo, Italy; 2Respiratory Medicine, Department of Medical Sciences, University of Ferrara, Ferrara, ItalyAbstract: Asthma and chronic obstructive pulmonary disease (COPD) are among the most common chronic diseases worldwide, characterized by a condition of variable degree of airway obstruction and chronic airway inflammation. A large body of evidence has demonstrated the importance of small airways as a pharmacological target in these clinical conditions. Despite a deeper understanding of the pathophysiologic…
Obstruction theory in action accessible categories
2013
Abstract We show that, in semi-abelian action accessible categories (such as the categories of groups, Lie algebras, rings, associative algebras and Poisson algebras), the obstruction to the existence of extensions is classified by the second cohomology group in the sense of Bourn. Moreover, we describe explicitly the obstruction to the existence of extensions in the case of Leibniz algebras, comparing Bourn cohomology with Loday–Pirashvili cohomology of Leibniz algebras.

In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differ…
Interruption of CD28-mediated costimulation during allergen challenge protects mice from allergic airway disease
2012
Background Allergic asthma is a T H 2-promoted hyperreactivity with an immediate, IgE, and mast cell–dependent response followed by eosinophil-dominated inflammation and airway obstruction. Objective Because costimulation by CD28 is essential for T H 2 but not T H 1 responses, we investigated the effect of selective interference with this pathway in mice using the models of ovalbumin and house dust mite–induced airway inflammation. Methods To study the role of CD28 in the effector phase of allergic airway inflammation, we developed an inducibly CD28-deleting mouse strain or alternatively used a CD28 ligand-binding site–specific mouse anti-mouse mAb blocking CD28 engagement. Results We show …
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…
Role of octreotide, scopolamine butylbromide, and hydration in symptom control of patients with inoperable bowel obstruction and nasogastric tubes: A…
2000
Bowel obstruction may be an inoperable complication in patients with end-stage cancer. Scopolamine butylbromide (SB) and octreotide (OCT) have been successfully used with the aim of reducing gastrointestinal (GI) secretions to avoid placement of a nasogastric tube (NGT); however, there have been no comparative studies concerning the efficacy of these drugs. Furthermore, there is little information about the role played by parenteral hydration in symptom control of these patients. In a prospective trial that involved all 17 inoperable bowel-obstructed patients presenting to our services with a decompressive NGT, patients were randomized to OCT 0.3 mg/day or SB 60 mg/day for 3 days through a …
Usage of BODE index to estimate the results of rehabilitation of patients with chronic obstructive lung disease
2008
Abstract: BODE index is the prognostic indicator in chronic obstructive lung disease, in which beyond bronchial obstruction the body mass index, dyspnea and competence exercise are taken into consideration. The indicator consists of few elements: B – BMI, O – obturation, D – dyspnea, E – exercise, taking into consideration various constitutional aspects of disease. The purpose of the paper was usage of BODE index in estimation of results of rehabilitation of patients with Chronic Obstructive Lung Disease. 60 in- hospital patients with chronic obstructive lung disease were examined, in Specialized Hospital MSWiA (Ministry of Interior and Administration) in Glucholazy. The pa-tients, who were…
Spirometric criteria to diagnose airway obstruction in the elderly: fixed ratio vs. lower limit of normal.
2015
COPD is the most common chronic lung disease. It becomes more prevalent with increasing age but remains under-diagnosed in the elderly. A heated debate concerns the most suitable way to diagnose airway obstruction in this age group. Most COPD guidelines recommend to use a FEV1/FVC of 0.70 as threshold to define an obstructive ventilatory defect. While the use of a 0.70 ratio may be simple, it may result in under-diagnosis of airflow obstruction in young people and over-diagnosis in the elderly due to an age-related decline in pulmonary volumes, especially in FEV1. This might lead to unnecessary use of medications and increased risk of adverse effects. A proposed strategy for reducing the mi…
Hsp60 and Hsp10 down-regulation predicts bronchial epithelial carcinogenesis in smokers with chronic obstructive pulmonary disease.
2006
BACKGROUND. The relation between smoking, chronic obstructive pulmonary disease (COPD), and lung cancer (LC) is an open field of investigation. A higher frequency of adenocarcinoma has been reported in patients with COPD. Heat shock proteins (Hsps) are implicated in tumoral cell growth and differentiation. The aim of the present study was to investigate the expression of Hsp60 and Hsp10 in bronchial biopsies from smokers with COPD and in 10 lung cancer patients and to evaluate the association between Hsps expression and carcinogenetic steps of LC. METHODS. An immunohistochemical study was performed for Hsp60 and Hsp10 in bronchial biopsies from 35 COPD (postbronchodilator forced expiratory …
