RESUMO

The increasing intake of ultra-processed (UP) foods is causing changes in the profile of food and nutrient consumption, negatively influencing consumer behavior. The present study aimed to evaluate the influence of UP foods on the diet of Brazilian adults, verifying the association between its increasing contribution to total energy and trends in the consumption of other NOVA groups, food subgroups, energy consumption, and macro- and micronutrients. We conducted an observational, cross-sectional study of a probability sample of 921 manufacturing workers in the state of Rio Grande do Norte, Brazil, from a combined stratified and two-stage survey. Trends in consumption across quintiles of UP food contribution to the total energy intake were tested with linear regression. The results showed that higher UP food consumption is associated with a higher intake of energy, carbohydrates and total-, mono- and polyunsaturated fats, saturated fats and trans fats, and the micronutrients calcium, iron and thiamine; and higher consumption of ready-to-eat foods, accompanied by lower consumption of foods that require preparation, such as beans, tubers and roots, vegetables and fruits, which may represent a risk for the development of non-transmissible chronic diseases in this population.

RESUMO

In rats, lisdexamfetamine (LDX) induces manic-like behaviors such as hyperlocomotion and increases in appetitive 50-kHz ultrasonic vocalizations (USV), which are prevented by antimanic drugs, such as lithium. Inhibition of glycogen synthase kinase 3 beta (GSK3ß) and antioxidant activity have been associated with antimanic effects. Thus, the aim of the present study was to evaluate the possible antimanic-like effects of andrographolide (ANDRO), a GSK3ß inhibitor, on LDX-induced hyperlocomotion and 50-kHz USV increases. In addition, the effect of ANDRO was studied on LDX-induced oxidative stress. Lithium was used as positive control. Adult Wistar rats were treated with vehicle, lithium (100 mg/kg i.p., daily) or ANDRO (2 mg/kg i.p., 3 times a week) for 21 days. On the test day, either 10 mg/kg LDX or saline was administered i.p. and USV and locomotor activity were recorded. LDX administration increased the number of 50-kHz calls, as well as locomotor activity. Repeated treatment with lithium or ANDRO prevented these effects of LDX on 50-kHz USV and locomotor activity. LDX increased lipid peroxidation (LPO) levels in rat striatum and both lithium and ANDRO prevented this effect. LPO levels in rat striatum were positively correlated with increases in 50-kHz USV emission as well as hyperlocomotion. In conclusion, the present results indicate that ANDRO has antimanic-like effects, which may be mediated by its antioxidant properties.

RESUMO

Motivations for food choices may determine consumption, and understanding that relationship may help direct strategies for formulating diets. This study aimed to identify associations between motivations for food choices and consumption of food groups. An observational cross-sectional survey was conducted in 921 manufacturing workers from 33 companies in Brazil, based on a stratified two-stage probability sample. Motivations for food choices were assessed with the Food Choice Questionnaire, and intake of food groups was measured using 24-h dietary recall. Consumption was classified into 31 food groups defined according to their nutritional value and the NOVA classification. Data were analyzed with multilevel mixed-effects regression. The results showed that sensory appeal and price were the most important motivations for food choices, while ethical concern was less important. Sensory appeal was positively associated with consumption of industrialized condiments (p = 0.022), price showed a negative correlation with consumption of plant oils (p = 0.022), ethical concern showed positive correlation within consumption white meat (p = 0.065) and negative correlation within pasta dishes (p < 0.001). Regarding the NOVA classification, health correlated with an increase in consumption of unprocessed foods (p = 0.017) and weight control with a decrease in consumption of processed culinary ingredients (p = 0.057).

RESUMO

INTRODUCCIÓN: La Functional Ambulation Classification (FAC) es la única escala que clasifica la marcha de individuos con esclerosis múltiple e ictus en categorías de deambulación. Sin embargo, la FAC sólo está disponible en la versión en inglés y los estudios realizados en Brasil la han utilizado sin una traducción y análisis adecuados de propiedades psicométricas. OBJETIVO: Traducir y adaptar culturalmente la FAC para el portugués brasileño y probar su fiabilidad y validez concurrente en individuos afectados por ictus. PACIENTES Y MÉTODOS: La traducción y la adaptación transcultural implicaron seis pasos. La fiabilidad interevaluador se probó con cinco fisioterapeutas que vieron vídeos de la marcha de las personas afectadas por ictus y, después de un intervalo mínimo de una semana, los vieron por segunda vez para determinar la fiabilidad intraevaluador. La validez concurrente se determinó correlacionando la FAC con el resultado de la prueba de marcha de 10 metros (PM 10m). RESULTADOS: La fiabilidad intraevaluador varió entre un valor kappa de 0,68-0,95 (p = 0,001), y la fiabilidad interevaluador, un valor kappa de 0,517-0,794 (p = 0,001). La correlación entre la FAC y la PM 10 m fue rs = 0,771 (p = 0,001). CONCLUSIÓN: La traducción, la adaptación transcultural y el análisis de las propiedades psicométricas demostraron que la FAC es una medida clínica válida y fiable para clasificar la deambulación de los individuos brasileños afectados por ictus en un entorno clínico


INTRODUCTION. The Functional Ambulation Classification (FAC) is the only scale that classifies the gait of individuals with multiple sclerosis and stroke victims into ambulation categories. However, the FAC is only available in English and studies conducted in Brazil have used the FAC without an adequate translation and analysis of its measurement properties. AIM. To translate, cross-culturally adapt the FAC to Brazilian Portuguese, test its reliability and concurrent validity on stroke survivors. PATIENTS AND METHODS. The translation and cross-cultural adaptation involved six steps. Inter-observer reliability was tested with five physiotherapists who watched videos of the gait of the stroke survivors and watched a second time after at least one week for the determination of intra-observer reliability. Concurrent validity was determined by correlating the FAC with the result of the 10-meter Walk Test (10 mWT). RESULTS. Intra-observer reliability ranged from kappa 0.680 to 0.952 (p = 0.001) and inter-observer reliability ranged from kappa 0.517 to 0.794 (p = 0.001). The correlation between the FAC and 10mWT was rs = 0.771 (p = 0.001). CONCLUSION. The translation, cross-cultural adaptation and measurement properties demonstrated that the FAC is a valid, reliable clinical measure for the categorization of ambulation in the Brazilian population of stroke survivors in a clinical setting

RESUMO

BACKGROUND: The Brazilian Workers Food Program (WFP) is a public policy program of nutritional assistance to workers, with the main objective of improving nutritional conditions, which was implemented 40 years ago and serves over 21.4 million workers. OBJECTIVES: To compare the long-term change in anthropometric indicators of the nutritional status and dietary intake between workers of manufacturing industries adherent to and non-adherent to the WFP. METHODS: A prospective cohort study, based on a combined stratified and multistage probability sampling, was carried out, with two waves with a 4-year interval. The change in body mass index (BMI), waist circumference (WC) and dietary intake at lunch by the 24-hour recall method were compared between groups with analysis of covariance. RESULTS: A total of 273 workers in 16 industries from an initial cohort of 1069 workers in 26 industries of the State of Rio Grande do Norte in Brazil were evaluated in the two waves. The mean age was 37±10 years and 53.1% were male, with no differences between groups in age and sex distribution. BMI increased in both groups (0.44 kg/m2 in non-WFP, p = 0.003, and 0.56 kg/m2 in WFP, p = 0.0006) and WC increased in the WFP group (1.50 cm, p = 0.0006). BMI change over time did not show statistical differences between groups (p = 0.54) but WC had a greater increase in the WFP group (difference 1.37 cm, p = 0.047). There were no differences between groups in the change over time of the dietary intake. CONCLUSION: BMI and WC increased over time in manufacturing workers of industries both adherent and non-adherent to the WFP, but with a greater increase of WC in the WFP group. In order to achieve the objectives of the WFP, there will be a need for periodic evaluation and monitoring of nutritional indicators in these workers and implementation of monitoring and enforcement actions of the WFP.
