- ItemAcute bronchodilator responsiveness in subjects with and without airflow obstruction in five Latin American cities: The PLATINO study(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010) Montes de Oca, Maria; Perez Padilla, Rogelio; Talamo, Carlos; Halbert, Ronald J.; Moreno, Dolores; Victorina Lopez, Maria; Muino, Adriana; Jose Roberto, B. Jardim; Valdivia, Gonzalo; Pertuze, Julio; Ana Maria, B. Menezes; PLATINO TeamBackground: Acute bronchodilator responsiveness is an area of discussion in COPD. No information exists regarding this aspect of the disease from an unselected COPD population. We assessed acute bronchodilator responsiveness and factors influencing it in subjects with and without airway obstruction in an epidemiologic sample.
- ItemChronic bronchitis phenotype in subjects with and without COPD: The PLATINO study(EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2012) Montes de Oca, Maria; Halbert, Ronald J.; Victorina Lopez, Maria; Perez Padilla, Rogelio; Talamo, Carlos; Moreno, Dolores; Muino, Adriana; Jardim, Jose Roberto; Valdivia, Gonzalo; Pertuze, Julio; Menezes, Ana Maria B.
- ItemChronic obstructive pulmonary disease and body mass index in five Latin America cities: The PLATINO study(W B SAUNDERS CO LTD, 2008) de Oca, Maria Montes; Talamo, Carlos; Perez Padilla, Rogelio; Jardim, Jose Roberto B.; Muino, Adriana; Lopez, Maria Victorina; Valdivia, Gonzalo; Pertuze, Julio; Moreno, Dolores; Halbert, Ronald J.; Menezes, Ana Maria B.; Platino TeamBackground: The body mass index (BMI) is a prognostic factor for chronic obstructive pulmonary disease (COPD). Despite its importance, little information is available regarding BMI alteration in COPD from a population-based study. We examined characteristics by BMI categories in the total and COPD populations in five Latin-American cities, and explored the factors influencing BMI in COPD.
- ItemFrequency of Self-Reported COPD Exacerbation and Airflow Obstruction in Five Latin American Cities The Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar (PLATINO) Study(ELSEVIER SCIENCE BV, 2009) Montes de Oca, Maria; Talamo, Carlos; Halbert, Ronald J.; Perez Padilla, Rogelio; Victorina Lopez, Maria; Muino, Adriana; Jardim, Jose Roberto B.; Valdivia, Gonzalo; Pertuze, Julio; Moreno, Dolores; Menezes, Ana Maria B.Background: Recurrent exacerbations are common in COPD patients. Limited information exists regarding exacerbation frequency in COPD patients from epidemiologic studies. We examined the frequency of self-reported exacerbations and the factors influencing exacerbation frequency among COPD patients in a population-based study conducted in Latin America.
- ItemHealth status perception and airflow obstruction in five Latin American cities: The PLATINO study(W B SAUNDERS CO LTD, 2009) Montes de Oca, Maria; Talamo, Carlos; Halbert, Ronald J.; Perez Padilla, Rogelio; Victorina Lopez, Maria; Muino, Adriana; Jardim, Jose Roberto B.; Valdivia, Gonzalo; Pertuze, Julio; Moreno, Dolores; Menezes, Ana Maria B.; PLATINO TeamBackground: COPD is a highly prevalent disease but underdiagnosed, undertreated and possibly under-recognized by patients. Limited information exists regarding patients' perception of COPD severity. We compared patients' general, health status perception, degree of breathlessness and physical activity limitation with the severity of their respiratory condition measured by airway obstruction, in a population-based sample.
- ItemThe chronic bronchitis phenotype in subjects with and without COPD: the PLATINO study(EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2012) Montes de Oca, Maria; Halbert, Ronald J.; Victorina Lopez, Maria; Perez Padilla, Rogelio; Talamo, Carlos; Moreno, Dolores; Muino, Adrianna; Jardim, Jose Roberto B.; Valdivia, Gonzalo; Pertuze, Julio; Menezes, Ana Maria B.Little information exists regarding the epidemiology of the chronic bronchitis phenotype in unselected chronic obstructive pulmonary disease (COPD) populations. We examined the prevalence of the chronic bronchitis phenotype in COPD and non-COPD subjects from the PLATINO study, and investigated how it is associated with important outcomes.
- ItemUse of respiratory medication in five Latin American cities: The PLATINO study(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2008) de Oca, Maria Montes; Talamo, Carlos; Perez Padilla, Rogelio; Lopez, Maria Victorina; Muino, Adriana; Jardim, Jose Roberto B.; Valdivia, Gonzalo; Pertuze, Julio; Moreno, Dolores; Halbert, Ronald J.; Menezes, Ana Maria B.; PLATINO TeamBackground: There is scanty information regarding respiratory medication prescription pattern in Latin America. We examined the use of bronchodilators and corticosteroids in a population-based study conducted in five Latin American cities.
