[EX Q]: Context: Given the high prevalence of obesity and noncommunicable diseases in Mexico and the key role of dietary quality in these conditions, it is important to determine Mexicans' adherence to dietary recommendations.", 'Our aim was to estimate the percentage of the Mexican population who adhere to dietary recommendations for key food groups.', 'We analyzed 7983 participants aged ≥5 y from the nationally representative Mexican National Health and Nutrition Survey 2012. Dietary intake data were collected by using one 24-h recall and a repeated 24-h recall in 9% of the sample. We used the National Cancer Institute method for episodically consumed foods, which uses a 2-part (probability and amount) mixed regression model to estimate the usual intake distribution and its association with sociodemographic variables.', 'For the food groups that are encouraged, only 1-4% of the population (range across sex and age groups) reached the recommended intake of legumes, 4-8% for seafood, 7-16% for fruit and vegetables, and 9-23% for dairy. For food groups that are discouraged, only 10-22% did not exceed the recommended upper limit for sugar-sweetened beverages, 14-42% for high saturated fat and/or added sugar (HSFAS) products, and 9-50% for processed meats, whereas the majority (77-93%) did not exceed the limit for red meat. A lower proportion of adolescents than children and adults adhered to recommendations for several food groups. Participants with higher socioeconomic status (SES) and living in urban areas consumed more (probability of consuming and/or amount consumed) fruit and vegetables, dairy, and HSFAS products, but they consumed fewer legumes than those of lower SES and living in rural areas.
Answer: These results reveal the poor dietary quality of the Mexican population and the urgent need to shift these habits. If current intakes continue, the burden of disease due to obesity and noncommunicable chronic diseases will likely remain elevated in the Mexican population.
[EX A]: Does adherence to Dietary Recommendations for Food Group Intakes be Low in the Mexican Population?

[EX Q]: Context: The aim of this study was to visualize early stage prostate cancer (Cap) in a clinical setting. In previous studies, the results of magnetic resonance imaging (MRI) for screening Cap have rarely been confirmed by well-designed multisite prostate biopsy.', 'The prostate glands of 90 men with elevated prostate-specific antigen (PSA) were imaged by dynamic contrast-enhanced MRI (DCE-MRI) before transrectal ultrasound-guided 14-cores prostate biopsy. Each core was divided into three subcore fractions (total of 42 fractions) to generate a histological localization diagram, which was compared with localization-visualized DCE-MRI.', "The detection rate of Cap in 57 patients with PSA < 10.0 ng/ml was 36.8% as determined by the initial biopsy. DCE-MRI uncovered 92.9% of the clinically significant Caps and its specificity was 96.2% for the first biopsy session. One case with positive DCE-MRI and a negative primary biopsy was positive with additional biopsies. All of 26 DCE-MRI positive cases had significant Cap, and two of eight patients with histological Cap and negative or equivocal imaging had significant cancer. In total, 9 of 20 cases with DCE-MRI stage T2 underwent radical prostatectomy. All of them had organ-confined disease, although 33-77% (mean 63%) of them were expected to be rated T3 or higher by Partin's table.
Answer: DCE-MRI can identify early stage Cap with high sensitivity and specificity, and can predict the histological grade to some extent. DCE-MRI prior to biopsy should be applied to younger patients with surgical indications. Otherwise, we recommend the definitive diagnosis of Cap by utilizing DCE-MRI alone.
[EX A]: Is dynamic contrast-enhanced magnetic resonance imaging ( DCE-MRI ) a useful modality for the precise detection and staging of early prostate cancer?

[EX Q]: Context: Atopic dermatitis (AD) often develops in infancy as the first manifestation of the atopic phenotype. Wheezing is also common in infancy, but it is less clear whether infant wheezing should be considered as an atopic phenotype. If infant wheeze and AD share a common aetiology, this would indicate that infant wheezing is an atopic phenotype.', 'To investigate whether potential risk factors for infant wheeze and AD have similar effects on these 2 phenotypes, indicating a common etiology.', 'A total of 34.793 mother-child pairs enrolled in the Danish National Birth Cohort were followed prospectively. Information on wheezing episodes, AD, and prenatal, perinatal, and postnatal risk factors was collected by interview at 12 and 30 weeks of gestation, at 6 and 18 months of age, and by linkage to the Danish Medical Birth Register. Data were analyzed by binary and polytomous logistic regression models.', 'The following variables had significantly differential effects on infant wheezing and AD: parental hay fever, parental asthma, parental AD, sex, maternal age, maternal occupation, smoking during pregnancy, season of birth, birth weight, gestational age, head circumference, breast-feeding, number of older siblings, day care attendance, and pets in the home.
Answer: The majority of risk factors had differential effects on infant wheeze and AD indicative of a different etiology. Infant wheezing does not seem to be etiologically linked to the epidemic of atopic disease, and infant wheezing should not be used as an indicator of the atopic phenotype.
[EX A]:
Do differential effects of risk factors on infant wheeze and atopic dermatitis emphasize a different etiology?
