PROBLEM: An association between obesity and otitis media with effusion (OME) has been previously reported. The aim of this study was to evaluate the association between dietary intake and OME when adjusting obesity.', 'We analyzed the differences in dietary intake between children with/without OME who were 4 through 13 years of age using data from a large population-based survey - the Korea National Health and Nutrition Examination Survey - from 2008 through 2012. Data from 4359 participants were analyzed using simple and multiple logistic regression analyses with complex sampling.', 'The BMI category, the proportion of total calorie intake, protein intake, water intake, and Na intake (intake/recommendation), and the distribution of carbohydrate intake were not associated with OME. The distribution of fat intake was associated with OME (each 10% increase of fat calories/total calories: unadjusted odds ratio [OR]=1.331, 95% confidence interval [CI]=1.016-1.744, P=0.038; age- and sex-adjusted OR=1.359, 95% CI=1.028-1.797, P=0.031; adjusted for age, sex and other factors OR=1.392, 95% CI=1.054-1.839, P=0.020). Based on BMI subgroup analysis, the distribution of fat intake was associated with OME in the healthy weight group (each 10% increase of fat calories/total calories: unadjusted OR=1.393, 95% CI=1.017-1.909, P=0.039; adjusted OR=1.470, 95% CI=1.051-2.055, P=0.024) but not in the obese group.

SOLUTION: Is a high-fat diet associated with otitis media with effusion?

PROBLEM: To assess the role of Notch activation in predicting bevacizumab efficacy in colorectal cancer (CRC).', 'Notch activation was evaluated by immunohistochemistry (IHC) on 65 CRC enrolled within randomized clinical trials assessing first-line bevacizumab-based chemotherapy and on 21 CRC treated with chemotherapy alone.', 'Strong Notch (IHC 3+) activation was negatively associated with response (18 vs 62% in low Notch cases [IHC 0, 1, 2+]; p = 0.016), progression-free survival (4.9 vs 12.1 months; p = 0.002) and overall survival (19.3 vs 30.4 months; p = 0.039). No correlation was found between Notch activation and clinical outcome in CRC treated with chemotherapy alone.

SOLUTION: Does strong Notch activation hinder bevacizumab efficacy in advanced colorectal cancer?

PROBLEM: To investigate which single quantitative electro-encephalographic (QEEG) marker or which combination of markers correlates best with Alzheimer's disease (AD) severity as measured by the Mini-Mental State Examination (MMSE).", 'We compared quantitative EEG markers for slowing (relative band powers), synchrony (coherence, canonical correlation, Granger causality) and complexity (auto-mutual information, Shannon/Tsallis entropy) in 118 AD patients from the multi-centric study PRODEM Austria. Signal spectra were determined using an indirect spectral estimator. Analyses were adjusted for age, sex, duration of dementia, and level of education.', 'For the whole group (39 possible, 79 probable AD cases) MMSE scores explained 33% of the variations in relative theta power during face encoding, and 31% of auto-mutual information in resting state with eyes closed. MMSE scores explained also 25% of the overall QEEG factor. This factor was thus subordinate to individual markers. In probable AD, QEEG coefficients of determination were always higher than in the whole group, where MMSE scores explained 51% of the variations in relative theta power.

SOLUTION:
Do quantitative EEG markers relate to Alzheimer 's disease severity in the Prospective Dementia Registry Austria ( PRODEM )?
