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 Output:
Does adherence to Dietary Recommendations for Food Group Intakes be Low in the Mexican Population?

Context: Increasing evidence points to the inflammatory character of atherosclerosis and several parameters of inflammation have been proposed as cerebrovascular risk markers. The objective of the research was to examine the connection of serum inflammatory parameters and ultrasound (US) characteristics of the structure and size of carotid plaque. We assumed that the number of leukocytes (Le) was an indicator of carotid plaque instability and an increased risk of stroke.', 'Serum inflammatory parameters: erythrocyte sedimentation rate in the first (ESR I) and second hour (ESR II), the number of Le, high sensitivity C-reactive protein (hsCRP) and fibrinogen were measured by standard methods. All the subjects (n = 75) were divided into 3 groups (symptomatic, asymptomatic and control). US evaluation of extracranial carotid arteries was performed in a duplex system. Plaques were classified into categories according to stenosis percentage (≥ 50%, < 50%) and pursuant to echomorphological characteristics (Gray-Weale classification). In the subjects with stroke an ischemic lesion was confirmed by computed tomography.', 'The average values of biochemical parameters in the symptomatic group were: ESR I 29.57 ± 29.87 cm, ESR II 51.60 ± 36.87 cm, the number of Le 10.10 ± 3.20 x 10⁹ U/L, hsCRP 8.15 ± 5.50 mg/L and fibrinogen 4.03 ± 0.70 g/L. The average values of all testing biochemical parameters in symptomatic patients were significantly higher than in the asymptomatic ones and the control group: for ESR I (p < 0.05) and ESR II (p < 0.05); for the number of Le (p < 0.001); for hsCRP (p < 0.001) and fibrinogen (p < 0.001). Category I of echomorphological characteristics in the symptomatic group was present in 66.7% of the cases and it was significantly higher than in the asymptomatic (40.0%; p < 0.05) and the control group (20.0%; p < 0.01). Univariate logistic regression analysis confirmed that all testing biochemical parameters are indicators of stroke risk. Multivariate logistic regression analysis confirmed a statistically significant correlation of the number of Le and stroke risk, while the increase in the value by a unit of measurement was associated with the growth of risk by 3.22 times (from 1.67 to 6.22).
Answer: The number of Le is associated with the phenomenon of carotid plaque instability and may be a useful additional marker of increased risk for developing acute cerebral infarction.

Does leucocyte count indicate carotid plaque instability in stroke patients?

Context: Postictal inhibition (PI) is a decrease in excitability that follows an epileptic seizure and decreases probability of new seizure occurrence. PI may involve both increased inhibition and persisting elevated excitation. Our experiments tested whether shorter trains of weak stimuli are able to unmask this residual increase of excitability during the PI.', 'Four epileptic afterdischarges (ADs) were evoked by intense electrical stimulation (20 s, 8 Hz, current intensity at 5x threshold) of the neocortex in two groups (A, B) of Wistar rats. Before the first AD and during the 10-min interictal period, 8-Hz trains of four weak pulses (half of the intensity used for the AD triggering; 4P) were applied every 20 s in group B and a single pulse with similar parameters in group A.', 'The number of interictal epileptiform events evoked by 4P in the group B was significantly higher than that in the group A (evoked by single pulses) except after the second AD. Epileptic events were triggered by 4P also immediately after the AD termination.
Answer: It is apparent that weak stimulation can trigger epileptic phenomena during PI. Our results indicate that it is no longer possible to perceive PI only as persisting extreme and active inhibition. An appropriate stimulation can reveal more subtle (but important) excitatory events contributing to the functional status during the postictal period.
