Prenatal exposure to cooking gas and respiratory health in infants is modified by tobacco smoke exposure and diet in the INMA birth cohort study

2013

Background: Studies that have evaluated the association between exposure to gas appliances emissions at home with respiratory health in children obtained heterogeneous and limited results. The aim of this study is to analyze the association between the use of gas cooking at home during pregnancy and respiratory problems in children during their first year of life. Methods: In the years 2003 through 2008 pregnant women were enrolled in 4 Spanish areas and visited in different age-points following a common protocol. Outcomes studied (from a questionnaire) were any episode of lower respiratory tract infection (LRTI), wheezing, persistent cough, chestiness and otitis. The association between ex…

Influence of Walking as Physiological Training to Improve Respiratory Parameters in the Elderly Population.

2022

Walking as physiological training is reported to be an effective activity in order to beneficially influence and slow the onset of aging in healthy elderly people. However, insufficient evidence exists on how walking influences lung function in seniors. In our study, we aim to evaluate the effect of different types of walking on lung function in healthy seniors. The PubMed, Web of Science, Scopus and EBSCO Essentials databases were searched, while the methodological quality was assessed by the RoB2 tool. A total of seven studies (RCTs) published between 2002–2022 that met the eligibility criteria were analysed in this review. All participants were older adults without any specific associate…

Lung Fibrosis and Fibrosis in the Lungs: Is It All about Myofibroblasts?

2022

In the lungs, fibrosis is a growing clinical problem that results in shortness of breath and can end up in respiratory failure. Even though the main fibrotic disease affecting the lung is idiopathic pulmonary fibrosis (IPF), which affects the interstitial space, there are many fibrotic events that have high and dangerous consequences for the lungs. Asthma, chronic obstructive pulmonary disease (COPD), excessive allergies, clearance of infection or COVID-19, all are frequent diseases that show lung fibrosis. In this review, we describe the different kinds of fibrosis and analyse the main types of cells involved—myofibroblasts and other cells, like macrophages—and review the main fibrotic mec…

Hematological and ventilatory responses to a 3900 m altitude sojourn in an elite wheelchair-marathoner.

2022

This case study aimed to report blood markers and resting respiratory rate (RR) oscillations at sea level, during a 5-wk 3900 m altitude sojourn, and after returning to sea level in a 36-year-old professional wheelchair marathoner. Outcome measures plasma erythropoietin (EPO) concentration, hemoglobin, reticulocytes count, erythrocytes and hematocrit as well as RR were measured upon wakening 7-weeks pre-altitude, 7-days pre-altitude, 35 hours after arrival to altitude, on days 8, 15, 21, 28 and 35 at altitude, 6 and 16 days after returning to sea level. EPO increased up to 259 % (31.6 U l-1) 35 hours upon arrival at altitude and decreased below pre-altitude level (12.2 U l-1) on the 21st da…

Riociguat versus sildenafil on hypoxic pulmonary vasoconstriction and ventilation/perfusion matching

2017

Introduction Current treatment with vasodilators for pulmonary hypertension associated with respiratory diseases is limited by their inhibitory effect on hypoxic pulmonary vasoconstriction (HPV) and uncoupling effects on ventilation-perfusion (V'/Q'). Hypoxia is also a well-known modulator of the nitric oxide (NO) pathway, and may therefore differentially affect the responses to phosphodiesterase 5 (PDE5) inhibitors and soluble guanylyl cyclase (sGC) stimulators. So far, the effects of the sGC stimulator riociguat on HPV have been poorly characterized. Materials and methods Contraction was recorded in pulmonary arteries (PA) in a wire myograph. Anesthetized rats were catheterized to record …

Incidencia, prevalencia y riesgo anual de infección tuberculosa en niños de 6-7 años en la ciudad de Valencia. Aportación de las nuevas técnicas inmu…

2011

Objetivos: • Determinar la prevalencia de infección tuberculosa (IT) y el Riesgo Anual de Infección (RAI) en niños de 6‐7 años en la ciudad de Valencia. Analizar la asociación de IT con distintas variables sociodemográficas. • Describir la concordancia entre prueba de tuberculina (PT) y QuantiFERON‐TB Gold In‐Tube (QFT‐G‐IT), en el diagnóstico de IT. Evaluar si la sensibilización por Mycobacterias no tuberculosas (MNT) puede ser responsable de la discordancia entre PT (+) y QFT‐G‐IT (‐). Material y Métodos: Estudio observacional, longitudinal y prospectivo, con 2 mediciones, separadas 12 meses (años 2007‐08). Selección de colegios mediante muestreo aleatorio por conglomerados, incluyendo ni…

Overweight/obesity and respiratory and allergic disease in children : international study of asthma and allergies in childhood (ISAAC) phase two

2014

Background: Childhood obesity and asthma are increasing worldwide. A possible link between the two conditions has been postulated. Methods: Cross-sectional studies of stratified random samples of 8-12-year-old children (n=10 652) (16 centres in affluent and 8 centres in non-affluent countries) used the standardized methodology of ISAAC Phase Two. Respiratory and allergic symptoms were ascertained by parental questionnaires. Tests for allergic disease were performed. Height and weight were measured, and overweight and obesity were defined according to international definitions. Prevalence rates and prevalence odds ratios were calculated. Results: Overweight (odds ratio=1.14, 95%-confidence i…
