Rate of severe exacerbations, healthcare resource utilisation and clinical outcomes in patients with COPD in low-income and middle-income countries: results from the EXACOS International Study.

Introduction: The cerbations of hronic obstructive lung disease (COPD) and their utcome (EXACOS) International Study aimed to quantify the rate of severe exacerbations and examine healthcare resource utilisation (HCRU) and clinical outcomes in patients with COPD from low-income and middle-income countries.

Methods: EXACOS International was an observational, cross-sectional study with retrospective data collection from medical records for a period of up to 5 years. Data were collected from 12 countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Guatemala, Hong Kong, Mexico, Panama, Russia and Taiwan.

Immunogenicity, Reactogenicity, and Safety of AS01E-adjuvanted RSV Prefusion F Protein-based Candidate Vaccine (RSVPreF3 OA) When Co-administered With a Seasonal Quadrivalent Influenza Vaccine in Older Adults: Results of a Phase 3, Open-Label, Randomized Controlled Trial.

Background: Co-administration of vaccines against respiratory syncytial virus (RSV) and influenza can be considered given their overlapping seasonality, and may increase vaccine uptake and compliance. In this phase 3, open-label, randomized study, we evaluated the immunogenicity, reactogenicity, and safety of the AS01E-adjuvanted RSV prefusion F protein-based candidate vaccine (RSVPreF3 OA) when co-administered with a seasonal quadrivalent influenza vaccine (FLU-QIV) in older adults.

Methods: Participants aged ≥60 years (randomized 1:1) received either RSVPreF3 OA and FLU-QIV simultaneously on day 1 (Co-Ad group) or FLU-QIV on day 1 followed by RSVPreF3 OA on day 31 (sequential administration [SA] group).

Latin American Registry of Idiopathic Pulmonary Fibrosis (REFIPI): Clinical Characteristics, Evolution and Treatment.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible and frequently fatal disease. Currently there are national and multinational registries in Europe, United States, Australia and China to better understand the magnitude of the problem and the characteristics of the IPF patients. However, there are no national or regional registries in Latin America, so the objective of this study was to carry out a Latin American registry that would allow the identification of IPF patients in our region.
