Stabilization of asthma prevalence among adolescents and increase among schoolchildren (ISAAC phases I and III) in Spain,

ALLERGY, Issue 12 2004
L. García-Marcos
Background:, Most studies show a steep increase in asthma prevalence in the last decades, although few studies had applied the same methodology. Recent reports point out the possibility that the epidemic has come to an end. We have studied the prevalence of asthma in a very large sample of children, repeating the study eight years apart. Methods:, Repeated cross-sectional studies using the International Study of Asthma and Allergies in Childhood (ISAAC) protocol in a sample of Spanish schoolchildren 6,7 (parent-reported) and 13,14 (self-reported) years old in 1994,95 (phase I) and 2002,2003 (phase III). The number of participants was 42 417 in phase I and 42 813 in phase III. The participation rate was over 87% (13,14 years) and 70% (6,7 years). Results:, The prevalence of wheezing in the previous year in children aged 13,14 years was 9.0 and 9.3% for boys and 9.6 and 9.2% for girls for phases I and III, respectively. Children 6,7 years of age showed a substantial increase in wheezing in the previous year (7.0 and 10.7% for boys and 5.3 and 8.2% for girls). Other symptoms and severity indexes followed the same patterns. Conclusions:, In the last 8 years, the prevalence of asthma has not changed in 13,14-year-old Spanish children but has increased substantially in 6,7-year olds. [source]

Study of peripheral muscle strength and severity indexes in individuals with chronic obstructive pulmonary disease

PHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 3 2010
Diego Marmorato Marino
Abstract Background and Purpose.,Individuals with chronic obstructive pulmonary disease (COPD) present reduced peripheral muscle strength, which leads to impaired mobility and increased mortality risk. However, it is not clear whether there is any relationship between muscle strength, muscle mass and the body mass index, airflow obstruction, dyspnea, exercise performance (BODE) index scale, which is considered to be the best predictor of survival for individuals with COPD. The BODE Index is a multidimensional system that measures body composition (B), airway obstruction (O), dyspnea perception (D) and the ability to exercise (E), and rates the severity of the major changes found in individuals with COPD. The objective of this study was to verify any relationship between the BODE Index, muscle mass and maximum muscle strengths of the upper limb (UL) and lower limb (LL) in subjects with moderate to very severe COPD.,Methods.,Twenty-six individuals with moderate to very severe COPD were evaluated by body composition (body mass index and muscle mass), BODE Index, handgrip strength (HS) and one repetition maximum (1RM) test of the UL and LL.,Results.,There was a positive correlation (Pearson, p < 0.05) of peripheral muscle strength, evaluated by HS and 1RM (pectoral and triceps, round muscles and dorsal section, quadriceps), to muscle mass (0.74, 0.57, 0.74 and 0.62, respectively) and the distance walked in the six-minute walking test (0.52, 0.50, 0.46 and 0.58, respectively), but no correlation of muscle strength was found to forced expiratory volume in one second to dyspnea or the BODE Index.,Conclusion.,In accordance with the results of this study, peripheral muscle strength as measured y HS and 1RM is not related to the severity indexes for COPD, unlike UL and LL muscle strength. Therefore, UL and LL measurements now have an additional importance in COPD evaluation. Copyright © 2010 John Wiley & Sons, Ltd. [source]

Evaluation of Gossypium species for resistance to cotton leaf curl Burewala virus

ANNALS OF APPLIED BIOLOGY, Issue 1 2010
K.P. Akhtar
Cotton leaf curl disease (CLCuD), caused by cotton leaf curl Burewala virus (CLCuBV), has emerged as a major threat to cotton production in Pakistan. Resistance to CLCuBV was evaluated in cultivated and wild cotton genotypes representing six Gossypium species by visual symptom scoring and virus assessment using PCR tests. Considerable variation in responses was observed when using whitefly and graft transmission to inoculate Gossypium genotypes with CLCuBV in field and greenhouse experiments. Under field evaluation, all cultivated genotypes of Gossypium hirsutum and three genotypes of G. barbadense were susceptible. Eleven genotypes that represented six wild and cultivated Gossypium species were considered to be highly resistant as they were free from infection. Similar results were obtained when these genotypes were tested using whitefly transmission. To verify these findings, 132 cultivated and wild genotypes were tested by graft inoculation. All G. hirsutum genotypes (116 cultivated, 1 wild, 1 transgenic Coker-312 and 1 non-transgenic Coker-312), three G. barbadense genotypes and one G. thurberi genotype were highly susceptible and exhibited symptoms 9,12 days after grafting. Four genotypes of G. arboreum and one genotype of G. anomalum did not express symptoms but had a detectable level of virus. One genotype of G. herbaceum and three wild genotypes of G. hirsutum showed mild symptoms (severity indexes of 1,2) and exhibited delayed disease development. These genotypes were classified as moderately resistant to resistant. Resistant genotypes that were identified in this study will be useful sources for exploitation of breeding programmes aimed at developing CLCuBV-resistant varieties and increasing genetic diversity.
