RESUMEN

PURPOSE: Children with brain tumors experience cognitive late effects, often related to cranial radiation. We sought to determine differential effects of surgery and chemotherapy on brain structure and neuropsychological outcomes in children who did not receive cranial radiation therapy (CRT). METHODS: Twenty-eight children with a history of posterior fossa tumor (17 treated with surgery, 11 treated with surgery and chemotherapy) underwent neuroimaging and neuropsychological assessment a mean of 4.5 years (surgery group) to 9 years (surgery + chemotherapy group) posttreatment, along with 18 healthy sibling controls. Psychometric measures assessed IQ, language, executive functions, processing speed, memory, and social-emotional functioning. Group differences and correlations between diffusion tensor imaging findings and psychometric scores were examined. RESULTS: The z-score mapping demonstrated fractional anisotropy (FA) values were ≥2 standard deviations lower in white matter tracts, prefrontal cortex gray matter, hippocampus, thalamus, basal ganglia, and pons between patient groups, indicating microstructural damage associated with chemotherapy. Patients scored lower than controls on visuoconstructional reasoning and memory (P ≤ .02). Lower FA in the uncinate fasciculus (R = -0.82 to -0.91) and higher FA in the thalamus (R = 0.73-0.91) associated with higher IQ scores, and higher FA in the thalamus associated with higher scores on spatial working memory (R = 0.82). CONCLUSIONS: Posterior fossa brain tumor treatment with surgery and chemotherapy affects brain microstructure and neuropsychological functioning years into survivorship, with spatial processes the most vulnerable. Biomarkers indicating cellular changes in the thalamus, hippocampus, pons, prefrontal cortex, and white matter tracts associate with lower psychometric scores.

RESUMEN

BACKGROUND: The efficacy and safety of an over-the-counter (OTC) 1% colloidal oatmeal cream versus a ceramide-based prescription barrier cream in children with mild-to-moderate atopic dermatitis (AD) were previously described. OBJECTIVES: Here, findings are reported for the Black/African American subgroup. METHODS: Patients were randomized to 1% oatmeal cream or prescription barrier cream twice daily or as needed for three weeks. Assessments included Eczema Area and Severity Index (EASI) scores, Investigator's Global Atopic Dermatitis Assessment (IGADA) scores, and patients'/caregivers' assessment of eczema signs and symptoms. RESULTS: Overall, 49 Black/African American children aged 2-15 years with mild/moderate AD were included. At week 3, mean (SD) changes from baseline in EASI scores were -2.4 (1.7) with 1% oatmeal cream and -2.1 (2.3) with barrier cream; improvements were observed from week 1. At week 3, mean (SD) changes from baseline in IGADA scores were -0.6 (0.7) and -0.7 (0.6), respectively. Improvements in subjective ratings of signs/symptoms of eczema were observed. Both study treatments were well tolerated. CONCLUSION: OTC 1% oatmeal cream was at least as effective and safe as prescription barrier cream in this population, providing a novel, fast-acting, and cost-effective option for the symptomatic treatment of mild-to-moderate AD in Black/African American children.

RESUMEN

BACKGROUND/AIMS: Performance on the Montreal Cognitive Assessment (MoCA) has been demonstrated to be dependent on the educational level. The purpose of this study was to identify how to best adjust MoCA scores and to identify MoCA items most sensitive to cognitive decline in incipient Alzheimer's disease (AD) in a Spanish-speaking population with varied levels of education. METHODS: We analyzed data from 50 Spanish-speaking participants. We examined the pattern of diagnosis-adjusted MoCA residuals in relation to education and compared four alternative score adjustments using bootstrap sampling. Sensitivity and specificity analyses were performed for the raw and each adjusted score. The interval reliability of the MoCA as well as item discrimination and item validity were examined. RESULTS: We found that with progressive compensation added for those with lower education, unexplained residuals decreased and education-residual association moved to zero, suggesting that more compensation was necessary to better adjust MoCA scores in those with a lower educational level. Cube copying, sentence repetition, delayed recall, and orientation were most sensitive to cognitive impairment due to AD. CONCLUSION: A compensation of 3-4 points was needed for <6 years of education. Overall, the Spanish version of the MoCA maintained adequate psychometric properties in this population.
