BACKGROUND: The ADL-Glittre test (TGlittre) was initially proposed to evaluate the activities of daily life (ADL) of adults with COPD that involve activities with the upper limbs in addition to walking. Recently, the test has been adapted for children (TGlittre-P), but no reference values have been proposed for its use in this population. The main objective of this study was to develop reference equations for the pediatric adaptation of the TGlittre.
METHODS: A cross-sectional study carried out over a period of 19 months. Children 6 -14 y old participated in the study. The study was rigorously controlled based on the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and on normal spirometry. Study subjects were evaluated for their biometric data (ie, weight, height, body mass index, body surface area, and length of the lower limbs) and spirometric data. Subjects then performed 2 TGlittre-P tests with an interval of 30 min between them. Statistical analysis included a Pearson correlation test to verify a correlation between time spent on the TGlittre-P and biometric variables such as gender and age. Subsequently, a multiple regression analysis was conducted for those variables. The level of signficance was set at a P of 0.05.
RESULTS: Eighty-seven children (44 girls) participated in the study. Age was the predictive variable with the greatest influence on the time spent on the TGlittre-P (male: adjusted R2 = 39.6%; female: adjusted R2 = 25.2%). The following equations were established: time spent on the TGlittre-P = 3.781 - 0.083 × age (female), and time spent on the TGlittre-P = 4.025 - 0.123 × age (male).
CONCLUSIONS: TGlittre-P reference equations were developed for females and males, with age being the most influential predictive variable in the test performed by children.

OBJECTIVES: To assess longitudinally small airway function in children born extremely prematurely and whether there was a correlation between airway function in infancy and at 11-14 years.
WORKING HYPOTHESES: There would be tracking of airways obstruction and small airway function would deteriorate during childhood in those born extremely prematurely.
STUDY DESIGN: A longitudinal study.
PATIENT-SUBJECT SELECTION: Thirty-five children with a mean gestational age of 26 weeks had lung function assessed at 1 year corrected and 11-14 years of age.
METHODOLOGY: Lung volumes were measured by helium gas dilution (FRCHe ) and plethysmography (FRCpleth ) and small airway function assessed by calculating the FRCHe :FRCpleth ratio. Airway function was assessed at 1 year corrected by measurement of airway resistance (Raw ) and at 11-14 years by assessment of Raw , forced expiratory flow from 75% of vital capacity (FEF75 ), and forced expiratory volume at one second (FEV1 ).
RESULTS: At the first assessment, the children had a mean (SD) FRCHe :FRCpleth of 0.90 (0.13) and at the second, 0.83 (0.12) (P = 0.035). There was a significant 0.54% decrease (95%CI: -1.02%, -0.06%) in FRCHe :FRCpleth for increased age per year after adjusting for birth weight, gestational age, sex, and bronchopulmonary dysplasia (P = 0.027). There were significant correlations between Raw at the first assessment and Raw (P = 0.012), FEF75 (P = 0.034), and FEV1 (P = 0.04) at 11-14 years.
CONCLUSIONS: These results demonstrate in those born extremely prematurely there is tracking of airway function during childhood.

Asthma and atopic dermatitis after early-, late-, and post-term birth.

OBJECTIVE: To assess the incidence and risk factors of asthma and atopic dermatitis by seven years of age after early-term (ET) (37+0 -38+6 weeks), full-term (FT) (39+0 -40+6 weeks), late-term (LT) (41+0 -41+6 weeks), and especially post-term (PT) (≥42 weeks) birth.
METHODS: Altogether, 965 203 infants born between 1991 and 2008 in Finland were investigated in ET, FT, LT, and PT groups. Data on asthma medication reimbursement and hospital visits for atopic dermatitis were retrieved from national health databases.
RESULTS: The frequencies of asthma medication reimbursement in the ET, FT, LT, and PT groups were 4.5%, 3.7%, 3.3%, and 3.2%, respectively. Hospital visits due to atopic dermatitis were most common after PT birth. Compared with FT births, ET births were associated with an increased risk of asthma (adjusted odds ratio (aOR), 95% confidence interval (CI) 1.20, 1.17-1.23), while LT (aOR, 95%CI 0.91, 0.89-0.93) births and PT (aOR, 95%CI 0.87, 0.83-0.92) births decreased this risk. PT birth (aOR, 95%CI 1.06, 1.01-1.10) predicted atopic dermatitis. From a population point of view, the most relevant risk factors for asthma were male sex, ET birth, smoking during pregnancy and birth by elective cesarean section, and for atopic dermatitis male sex, first delivery, birth in a level II hospital and birth by cesarean section.
CONCLUSIONS: Early-term birth was a predictor of asthma, and PT birth was associated with atopic dermatitis. Counseling against smoking and following strict indications for planned ET deliveries and cesarean sections may be means to reduce the risk of later asthma.

We examined common variation in asthma risk by conducting a meta-analysis of worldwide asthma genome-wide association studies (23,948 asthma cases, 118,538 controls) of individuals from ethnically diverse populations. We identified five new asthma loci, found two new associations at two known asthma loci, established asthma associations at two loci previously implicated in the comorbidity of asthma plus hay fever, and confirmed nine known loci. Investigation of pleiotropy showed large overlaps in genetic variants with autoimmune and inflammatory diseases. The enrichment in enhancer marks at asthma risk loci, especially in immune cells, suggested a major role of these loci in the regulation of immunologically related mechanisms.
