Irish Child Health Database - Peer Reviewed Papers

Database Search

How to use this database.

• Method 1- uses a free natural language approach.

  After choosing the object of the search – by ticking title, abstract, aims and objective, or author - enter a term, word or name in the ‘Search’ box to return references answering your research question.

• Method 2 - utilises key words.

  Those key words assigned from thesauruses of controlled vocabulary by the trained coders of international bibliographic databases.
  The controlled vocabularies key word are listed alphanumerically under 'Bibliographic database keywords' .
  Use the drop down menu to identity which 'key words' you are interested in to return references to answer your research question.

• Method 3 - is based on the indexing system

  developed by the researchers who compiled this database.
  It adopts a thematic approach to mapping Irish child health research. The themed areas represent outcomes mapped to the International Classification of Disease version 10 (ICD-10) or one of 23 other health-related themed outcomes. Themes are defined in Tables 5 to 7 (of the study report).
  Use the alphabetic drop down menu under ‘ICD-10 or themed health-related outcomes’ to identity which themed areas you are interested in to select references to answer your research question.

• Method 4 – allows papers to be searched by Study type.

  Indexing by study type offers a valuable insight into understanding the population impact of the topic of interest. More than 20 study types were identified across the 2,152 study papers. These are defined in Table 3 (of the study report). Within 'Study type' papers are further stratification by geographical region (Table 49), topic area of interest and study aims and objectives.
  Click on 'Study type' to select the type of study of interest, progressively select sub-categories by topic area or other sub-classification of interest to answer your research question.

The complete background, methods and findings from this mapping exercise are detailed in the study report.

• Antioxidants and oxidative stress in BAL fluid of atopic asthmatic children

  Published in:

  Pediatr Res, Vol: 53, Page: 375-81

  Publication Date:

  March 2003

  Aims & Objectives:

  The aim of this study was to compare the concentrations of antioxidants and protein carbonyls in bronchoalveolar lavage fluid of clinically stable atopic asthmatic children with our recently published reference intervals for nonasthmatic children

  Abstract:

  Earlier studies in adults have indicated that increased oxidative stress may occur in the blood and airways of asthmatic subjects. Therefore the aim of this study was to compare the concentrations of antioxidants and protein carbonyls in bronchoalveolar lavage fluid of clinically stable atopic asthmatic children (AA, n = 78) with our recently published reference intervals for nonasthmatic children (C, n = 124). Additionally, lipid peroxidation products (malondialdehyde) in bronchoalveolar lavage fluid and several antioxidants in plasma were determined. Bronchoalveolar lavage concentrations (median and interquartile range) of ascorbate [AA: 0.433 (0.294-0.678) versus C: 0.418 (0.253-0.646) micromol/L], urate [AA: 0.585 (0.412-0.996) versus C: 0.511 (0.372-0.687) micromol/L], alpha-tocopherol [AA: 0.025 (0.014-0.031) versus C: 0.017 (0.017-0.260) micromol/L], and oxidized proteins as reflected by protein carbonyls [AA: 1.222 (0.970-1.635) versus C: 1.243 (0.813-1.685) nmol/mg protein] were similar in both groups (p > 0.05 in all cases). The concentration of protein carbonyls correlated significantly with the number of eosinophils, mast cells, and macrophages in AA children only. Concentrations of oxidized proteins and lipid peroxidation products (malondialdehyde) correlated significantly in AA children (r = 0.614, n = 11, p = 0.044). Serum concentrations of ascorbate, urate, retinol, alpha-tocopherol, beta-carotene, and lycopene were similar in both groups whereas alpha-carotene was significantly reduced in asthmatics. Overall, increased bronchoalveolar lavage eosinophils indicate ongoing airway inflammation, which may increase oxidatively modified proteins as reflected by increased protein carbonyl concentrations.
