The prevalence of asthma increased worldwide until the 1990s, but since then there has been no clear temporal pattern. The present study aimed to assess time trends in the prevalence of current asthma, asthma-like symptoms and allergic rhinitis in Italian adults from 1990 to 2010. The same screening questionnaire was administered by mail or phone to random(More)
The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines underline that the presence of chronic cough and sputum production before airflow obstruction offers a unique opportunity to identify subjects at risk of chronic obstructive pulmonary disease for an early intervention. Current epidemiological data on these subjects are scant.(More)
In the early 1990s a multicentre survey on asthma was performed on the young adult population (European Community Respiratory Health Survey - ECRHS). This study is to be repeated in order to estimate changes in the prevalence of asthma-like symptoms during the last decade and to assess the social and economic costs of the disease and their variations among(More)
The role of genetic and environmental factors, as well as their interaction, in the natural history of asthma, allergic rhinitis and chronic obstructive pulmonary disease (COPD) is largely unknown. This is mainly due to the lack of large-scale analytical epidemiological/genetic studies aimed at investigating these 3 respiratory conditions simultaneously.(More)
The magnitude of a random telegraph signal (RTS) in nanoscale floating-gate devices has been experimentally investigated as a function of carrier concentration. Discrete current switching, which is caused by a single trap, has been found to be almost one order of magnitude higher with respect to what was predicted by the classical theory of carrier number(More)
This paper introduces a protograph-based method for designing q-ary LDPC codes for use with modulations larger than QPSK. Simulations focus on a GF(16), 16-QAM example. The proposed construction method achieves the maximum gain when the average column weight is chosen so that the linear minimum distance growth property is satisfied. In this region, the(More)
Spectral unmixing is an important technique for exploiting hyperspectral data. The presence of nonlinear mixing effects poses an important problem when attempting to provide accurate estimates of the abundance fractions of pure spectral components (endmembers) in a scene. This problem complicates the development of algorithms that can address all types of(More)
BACKGROUND Variations in the prevalence of respiratory symptoms according to geo-climatic factors could provide important clues to the knowledge of the aetiology of asthma. METHODS Geo-climatic variations in the prevalence of current asthma, allergic rhinitis and chronic cough, and phlegm were assessed on a random sample of 18 873 subjects (response rate(More)
BACKGROUND Few data are available on the asthma burden in the general population. We evaluated the level and the factors associated with the asthma burden in Europe. METHODS In 1999-2002, 1152 adult asthmatics were identified in the European Community Respiratory Health Survey (ECRHS)-II and the socio-economic burden (reduced activity days and hospital(More)
We assessed the infectiousness of human immunodeficiency virus (HIV)-seropositive and HIV-seronegative individuals with pulmonary tuberculosis (TB) in a prospective cohort study. We enrolled, evaluated, and followed 104 close contacts of HIV-seropositive pulmonary TB patients and 256 close contacts of HIV-seronegative pulmonary TB patients using a(More)
