Haemoglobin, iron status and lung function of adolescents participating in organised sports in the Finnish Health Promoting Sports Club Study
2020
ObjectivesTo compare laboratory test results and lung function of adolescent organised sports participants (SP) with non-participants (NP).MethodsIn this cross-sectional study, laboratory tests (haemoglobin, iron status), and flow-volume spirometry were performed on SP youths (199 boys, 203 girls) and their NP peers (62 boys, 114 girls) aged 14–17.ResultsHaemoglobin concentration <120/130 g/L was found in 5.8% of SP and 5.1% NP (OR 1.20, 95% CI 0.54 to 2.68). Ferritin concentration below 15 µg/L was found in 22.7% of both SP and NP girls. Among boys ferritin <30 µg/L was found in 26.5% of SP and 30.2% of NP (OR 0.76, 95% CI 0.40 to 1.47). Among SP iron supplement use was reported by 3…
Pathophysiological Factors in the Relationship between Chronological Age and Calculated Lung Age as Detected in a Screening Setting in Community-Dwel…
2016
Aim To explore the relationship between pathophysiological factors and premature lung aging in a cohort of community-dwelling subjects in a health-screening setting. Methods 16,107 pharmacy customers in Germany (5954 males, 10,153 females; mean age 59.7 years) participated in a lung function screening project by providing demographic data, including smoking status and known airway conditions and performing spirometry with a Vitalograph, a spirometry screening device. Lung age was calculated from the spirometric findings, and the difference between chronological age and calculated lung age was analyzed in its relationship to the demographic data in general linear models. Results In the overa…
Intrauterine and postnatal exposure to outdoor NO2 and lung function at school age
2020
Lungs are highly vulnerable to permanent harmful effects of environmental factors during their in-utero and early life development. The detrimental effects of air pollution on lung development are well known although studies mainly focused on the postnatal exposure period. We investigated the windows of susceptibility during pregnancy and first 7 postnatal years on the association between nitrogen dioxide (NO2) and lung function at the age of 7 years in the INMA cohort in Spain. We estimated monthly average exposure to NO2 for the prenatal and postnatal period at home address of 1230 children with temporally-adjusted land use regression models. Spirometry was performed at age 7. We estimate…
Early infancy BMI trajectories and lung function and asthma during childhood
2019
Previous studies assessing the association of birthweight and infant weight gain with lung function and asthma have focused on the difference between two time points or on growth patterns. Body mass index (BMI) trajectories, which integrate information on multiple aspects of growth, may allow a more accurate identification of children at higher risk of future respiratory diseases. We assessed the associations of BMI trajectories from birth to 4 years with lung function and current asthma at 7 years. We included 1399 participants from the population-based INMA birth cohort study. Five BMI trajectories were previously identified: ‘average birth size-slower BMI gain’, ‘higher birth size-accele…
Monitoring response to treatment in asthma management: food for thought
2004
Asthma is a chronic inflammatory disorder of the airways that is characterized by episodic symptoms. In this regard, asthma management has classically involved periodic re-assessment by the health-care provider, during which therapy is altered mainly based on clinical and physiological parameters, such as assessment of symptoms, spirometry and peak expiratory flow monitoring. In this context, various markers of airway inflammation (e.g. eosinophils in the induced sputum, nitric oxide in the exhaled air) have been proposed to assess the severity of asthma and to adjust the therapy accordingly. The evaluation of airway hyper-responsiveness with different stimuli has also been suggested as a n…
3 He-MRI-based vs. conventional determination of lung volumes in patients after unilateral lung transplantation: a new approach to regional spirometry
2002
Background: To use 3Helium (3He)-MRI in patients with unilateral lung grafts to assess the contributions of graft and native lung to total ventilated lung volume, and second to compare conventional measurements of intrapulmonary gas volume (spirometry, body plethysmography) with image-based volumetry of ventilated lung parenchyma visualized by hyperpolarized 3He-MRI. Methods: With Ethics Committee approval, five patients with single lung transplantation (SLTX) for idiopathic pulmonary fibrosis (IPF) underwent both conventional pulmonary function testing (PFT) and 3He-MRI of the lung. Intrapulmonary gas volume (GV) during the inspiratory breathhold for 3He-MRI was calculated from measured fu…
666 Pulmonary Abnormalities in Children and Adolescents with Type 1 Diabetes Mellitus
2012
Background and Aims Few studies are available on pulmonary function abnormalities in children with diabetes with controversial results. Spirometric abnormalities and reduction of lung diffusing capacity for carbon monoxide (DLCO) have been reported. A cross sectional study was designed to assess whether children and adolescents with type 1 diabetes have pulmonary dysfunction. Methods Spirometry measurements were performed and DLCO was measured. The final data analysis was conducted on 57 diabetics (mean age 14.4 + 3.09 years, 31 males) and 40 healthy controls (mean age 13.6 + 2.2 years, 19 males). Results Although FVC, FEV1, FEV1/FVC of diabetics were lower than in control, significant stat…
Asthma control, severity and lung function impairment through network analysis in children
2015
Background: Achieving and maintaining asthma control in children is the primary goal recommended by current guidelines. Aim: To identify risk factors associated with Asthma control and severity, as well as their relative weight. Methods: Within a consecutive series of outpatients visited in a three years period at the IBIM pediatric clinic, we selected 128 persistent asthmatics. A standardized medical interview was carried out to collect information on environmental risk factors, symptoms and comorbidities. Spirometry was performed using Pony FX, Cosmed, Italy; spirometric values were expressed as %pred using GLI-2012equation. Statistical analyses were performed by using R. Results: The ide…
Measuring lung function in asthmatic children: A spirometry and forced oscillation technique (FOT) comparison
2016
Background: Spirometry is the most common pulmonary function test used in asthma diagnosing. However, it requires good patient co-operation. FOT has gained increasing attention for the measurement of pulmonary function in children because it is performed at steady state breathing. Aim: To compare spirometry and FOT in order to discriminate severity of asthma according to GINA. Methods: Spirometry and FOT were performed in 176 out-patient asthmatic children (5-16 year), 100 (57%) with naive Persistent Asthma (PA) and 76 (43%) with Intermittent Asthma (IA), consecutively enrolled at the IBIM pediatric clinic. Two principal component analyses (PCA) were performed, the first (PCA1) based on FEV…
