Quality of life in idiopathic pulmonary fibrosis in Latin American countries.

Background: Idiopathic pulmonary fibrosis (IPF) is the most common Interstitial Lung Disease (ILD). It is characterized by dyspnoea and a progressive decline in lung function, which negatively affects life. This study aimed to evaluate Health-Related Quality of Life (HRQoL) in IPF patients in Latin American countries.

Why do avian responses to change in Arctic green-up vary?

Global climate change has altered the timing of seasonal events (i.e., phenology) for a diverse range of biota.

Effects of polycyclic aromatic hydrocarbons on gestational hormone production in a placental cell line: Application of passive dosing to in vitro tests.

Air pollution includes polycyclic aromatic hydrocarbons (PAHs), which have been correlated to endocrine disruptor pathways during early pregnancy. PAHs have been found in the placenta and cord blood, which may affect the hormones involved in placental development. We studied the effects of some airborne PAHs on beta human chorionic gonadotropin (β-hCG) and progesterone production by using a syncytial BeWo cell line as a placental model.

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.

Oversummering juvenile and adult Semipalmated sandpipers in Perú gain enough survival to compensate for foregone breeding opportunity.

Background: Age at maturity and the timing of first breeding are important life history traits. Most small shorebird species mature and breed as 'yearlings', but have lower reproductive success than adults. In some species, yearlings may defer northward migration and remain in non-breeding regions ('oversummering') until they reach 2 years of age.
