The impact of traditional literacy and education on health literacy in adolescents with asthma.

Introduction: People with low health literacy have poorer self-management of chronic diseases like asthma. Studies of parent health literacy and education level on the management of children's chronic illnesses reveal inconclusive results. We hypothesized a correlation between parent and adolescent health literacy in teens with asthma. Methods: Sociodemographic data were obtained; health literacy was assessed on adolescents and parents with three instruments: Rapid Estimate of Adolescent/Adult Literacy in Medicine (REALM), Single Item Literacy Screener (SILS) and Newest Vital Sign (NVS). Agreement between scores was examined by calculating weighted kappa statistics and performing Bowkers test of symmetry. Results: In all, 243 adolescents and 203 parents completed health literacy assessments yielding 198 paired observations. 9th-12th graders, 60.6% female, 72.7% African-American (AA), mean age: 15.3 years (±0.9). Parent education ranged from < high school (19.1%) to college graduate (24.0%). Agreement between adolescent and parent scores was poor: REALM (κw = 0.26), SILS (κw = 0.12), and NVS (κw = 0.29) and disagreement did not significantly differ by race. Positive correlations of moderate strength (overall and between racial groups) were found between reading scores and both REALM and NVS scores, and between REALM and NVS scores. Due to the inverse relationship of SILS scores with health literacy level, SILS scores (overall and between racial groups) were weakly and negatively correlated with reading scores, REALM and NVS. Conclusion: Correlation between education level and traditional literacy suggests that these are contributing factors to the health literacy of adolescents with asthma. Correlation between adolescent and caregiver health literacy was not supported.

Accurate automated detection of autism related corpus callosum abnormalities.

The importance of accurate early diagnostics of autism that severely affects personal behavior and communication skills cannot be overstated. Neuropathological studies have revealed an abnormal anatomy of the Corpus Callosum (CC) in autistic brains. We propose a new approach to quantitative analysis of three-dimensional (3D) magnetic resonance images (MRI) of the brain that ensures a more accurate quantification of anatomical differences between the CC of autistic and normal subjects. It consists of three main processing steps: (i) segmenting the CC from a given 3D MRI using the learned CC shape and visual appearance; (ii) extracting a centerline of the CC; and (iii) cylindrical mapping of the CC surface for its comparative analysis. Our experiments revealed significant differences (at the 95% confidence level) between 17 normal and 17 autistic subjects in four anatomical divisions, i.e. splenium, rostrum, genu and body of their CCs.
