Résumé

Introducción: Las bases de datos y las tablas de composición de alimentos (BDCA y TCA, respectivamente) contienen información sobre la composición química-nutricional de los alimentos. Objetivo: Definir las fuentes de los datos de composición de alimentos que se usan en Costa Rica y que impacto tienen a nivel de políticas públicas. Materiales y métodos. Se analizaron las TCA y BDCA disponibles en Costa Rica desde 1960 hasta el 2020. Se encuestaron usuarios de datos de composición de alimentos. Se analizaron los usos de estos datos y algunos alcances a nivel de política pública. Resultados: Se identifica la utilización predominante de datos de la BDCA de Estados Unidos, los datos nacionales son desactualizados en su mayoría y hay pocos datos de análisis directo (químico) de alimentos. Se evidencia la importancia de contar con datos propios, actualizados y representativos de composición de alimentos para la toma de decisiones en salud pública. Conclusiones: Se deben vincular las instituciones generadoras y compiladoras para maximizar los recursos para fortalecer la disponibilidad de datos de composición de alimentos en el país. Se evidencia la necesidad de generar un Sistema Nacional de Datos de Composición de Alimentos que se ajuste a las necesidades identificadas en cuanto a la calidad y presentación de la información(AU)


Introduction: Databases and food composition tables (FCDB and FCT, respectively) provide information about the chemical-nutritional composition of foods. Objective: of this work was to define the sources of food composition data used in Costa Rica and their impact on public policies. Materials and methods: It was analyzed which TCA and FCDB have been available in Costa Rica from 1960 to 2020. Users were surveyed about food composition data. It was analyzed the uses of these data and some of their impacts on public policy. Results: The predominant use of data from the U.S. FCDB is identified, the national data are mostly outdated, and there is little data from direct (chemical) analysis of food. The importance of having our own, up- to-date, and representative data on food composition for public health decision-making is evident. Conclusions: Generating and compiling institutions should be linked to maximize resources to strengthen the availability of food composition data in the country. The need to generate a National Food Composition Data System that meets the identified needs in terms of quality and presentation of information is evident(AU)

Résumé

Introduction: The confinement due to COVID-19 significantly affected people's food consumption, especially university students who had to adapt to virtual education. Objective: To determine the perception and food consumption frequency due to the COVID-19 pandemic among Peruvian students from a private university in Trujillo City, Peru. Materials and method: The research design was non-experimental, descriptive, and cross- sectional. The non-probabilistic sample consisted of 169 students and the instrument used was a virtual survey (Cronbach's alpha = 0.846). Results: It is shown that there is a higher frequency of young people (n = 116) and adolescents (n = 45) who participated in the study, and that the average age was 22.15 ± 3.77 years. Likewise, the Frequency of Consumption dimension, it showed a higher frequency in the "Sometimes" scale, where it is related to whether it exceeded the number of meals per day (34.9%), eating out of control (38.5%), desires to eat unhealthy food (32.0%) and whether it influenced eating (30.8%). Similarly, it was shown that the majority of respondents consumed fruits (68.6%) and vegetables (58.0%) and considered water consumption essential (98.3%). On the other hand, there was a higher frequency regarding the consumption of ultra-processed foods (n = 95, 56.2%). Conclusion: The population of a private university made up mostly of young people and adolescents perceives that there was a change in their diet during the COVID-19 pandemic(AU)

Résumé

ABSTRACT OBJECTIVE To analyze the consumption of critical nutrients and other sweeteners, according to the degree of food processing in the population of Antioquia. METHODS Cross-Sectional Study. The dietary intake of 4,382 participants of the Perfil Alimentario y Nutricional de Antioquia 2019 (Antioquia Food and Nutrition Profile 2019) was evaluated. Processed foods (PF) and ultra-processed products (UPP) reported by 24-hour recall were classified according to the Nova system. The Nutrient Profile Model (NPM) of the Pan American Health Organization (PAHO) was used. The amount of PF and UPP consumed with excess of critical nutrients related to chronic diseases (CD) was measured. The difference in average intake, the prevalence of excess intake, and the likelihood of inadequacy between groups with and without excess dietary content were assessed. RESULTS Nearly 50% of the PF and UPP consumed had excess in at least one critical nutrient. The population consumed daily one or more products with excess in free sugar (73.3%), total fat (75.2%), saturated fat (77.0%), sodium (83.9%), and/or sweeteners (36.8%). Those who consumed products with excessive amounts had a higher intake of total fat (> 5.8%); saturated fat (> 3.8%); and sodium (> 698.7 mg) in adults and adolescents, in children 5-10 years (> 659.2 mg), and in children under 5 years (> 498 mg). Those who consumed products with excessive amounts presented the greatest possibilities of dietary inadequacy. CONCLUSION The population of Antioquia that consumes PF and UPP with excessive amounts of free sugars, total fat, saturated fat, sodium, and/or sweeteners presents an unbalanced diet. Reducing the consumption of these products and returning to a natural and/or minimally processed diet may be an effective strategy to achieve the nutrient intake recommendations prioritized by PAHO in the population of Antioquia.


RESUMEN OBJETIVO Analizar el consumo de nutrientes críticos y otros edulcorantes, según el grado de procesamiento de los alimentos en la población Antioqueña. MÉTODOS En este estudio transversal, se evaluó el consumo alimentario de 4,382 participantes del Perfil Alimentario y Nutricional de Antioquia 2019. Los alimentos procesados (AP) y productos ultraprocesados (PUP) informados por recordatorio de 24 horas se clasificaron según sistema Nova. Se usó el Modelo de Perfil de Nutrientes (MPN) de la Organización Panamericana de la Salud (OPS). Se midió la cantidad de AP y PUP consumidos con exceso en nutrientes críticos, relacionados con las enfermedades crónicas (EC). Se evaluó la diferencia en el consumo promedio, la prevalencia del consumo excesivo, y las posibilidades de inadecuación entre los grupos que tenían una dieta con y sin contenido excesivo. RESULTADOS Cerca del 50% de los AP y PUP consumidos presentaba exceso en al menos un nutriente crítico. La población consumió diariamente uno o más productos con exceso en azúcar libre (73.3%), grasa total (75.2%), grasa saturada (77.0%), sodio (83.9%) y/o edulcorantes (36.8%). Quienes consumían productos con cantidades excesivas tenían una mayor ingesta de grasas totales (> 5.8%); grasas saturadas (> 3.8%); y sodio (> 698.7 mg) en adultos y adolescentes, en niños de 5-10 años (> 659.2 mg), y en menores de 5 años (> 498 mg). Quienes consumieron productos con cantidades excesivas presentaron las mayores posibilidades de inadecuación en la dieta. CONCLUSIÓN La población antioqueña que consume AP y PUP con cantidades excesivas de azúcares libres, grasas totales, grasas saturadas, sodio y/o edulcorantes, presenta una dieta desbalanceada. Reducir el consumo de estos productos y volver a una dieta natural y/o mínimamente procesada puede ser una estrategia efectiva para alcanzar las recomendaciones de ingesta de nutrientes priorizados por OPS en la población antioqueña.

Résumé

Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC's 7.97 ×103mm-3, RBC's 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.


Resumo O objetivo do presente estudo é avaliar os efeitos das nanopartículas de selênio no crescimento, hematologia e digestibilidade dos nutrientes de alevinos de Labeo rohita.

Résumé

Introduction: The litterfall production, foliar nutrient dynamics and decomposition are essential to maintain nutrient cycling, soil fertility, and carbon regulation in terrestrial ecosystems. With several studies addressing the variation of these processes, their dynamics in tropical dry forests (TDFs) remain unclear, due to its complex interaction of biotic and abiotic factors. Objective: To evaluate litterfall, nutrient potential return and use efficiency, and decomposition variation in a TDF successional gradient in Tolima, Colombia. Methods: We quantified litterfall from November 2017 to October 2019 in 12 plots distributed in four successional stages: initial, early, intermediate, and late forests. We identified key tree species in foliar litter production and characterized the foliar decomposition of these species. At the community level, we quantified the C, N and P potential return, the N and P use efficiency, and the C:N and N:P ratio. Subsequently, we analyze relationships between vegetation characteristics and some soil chemical properties with these ecological processes. Results: We found that total litterfall in late forests (8.46 Mg ha-1 y-1) was double that found in initial forests (4.45 Mg ha-1 y-1). Decomposition was higher in initial (k = 1.28) compared to intermediate (k = 0.97) and late forests (k = 0.87). The nutrient potential return didn't change along succession, but it did show differences between study sites. The structural development and species richness favored litterfall, while soil chemical conditions influenced nutrient returns and decomposition. Conclusions: TDFs could recover key ecosystem function related to litterfall and nutrient dynamics after disturbances cessation; however, the soil quality is fundamental in return and release of nutrients.


Introducción: La producción de hojarasca, la dinámica de nutrientes foliares y la descomposición son esenciales para mantener el ciclo de nutrientes, la fertilidad del suelo y la regulación del carbono en ecosistemas terrestres. Con diversos estudios que abordan estos procesos, su variación en los bosques secos tropicales (BSTs) permanece incierta, por su compleja interacción de factores bióticos y abióticos. Objetivo: Evaluar la caída de hojarasca, el retorno potencial de nutrientes y eficiencia de uso, y la variación en descomposición en un gradiente sucesional de un BST en Tolima, Colombia. Métodos: Cuantificamos la caída de hojarasca entre noviembre 2017 y octubre 2019 en 12 parcelas distribuidas en cuatro estados sucesionales: bosque inicial, temprano, intermedio y tardío. Identificamos las especies arbóreas clave en la producción de hojarasca y caracterizamos la descomposición foliar de estas especies. A nivel comunitario, cuantificamos el retorno potencial de C, N y P, la eficiencia de uso de N y P y la relación C:N y N:P. Posteriormente, analizamos las relaciones entre las características de la vegetación y algunas propiedades químicas del suelo con estos procesos ecológicos. Resultados: Encontramos que la caída total de hojarasca en los bosques tardíos (8.46 Mg ha-1 año-1) fue el doble de la hallada en bosques iniciales (4.45 Mg ha-1 año-1). La descomposición fue mayor en bosques iniciales (k = 1.28) en comparación con bosques intermedios (k = 0.97) y tardíos (k = 0.87). El retorno potencial de nutrientes no cambió con el avance de la sucesión vegetal, pero exhibió diferencias entre los sitios de estudio. El desarrollo estructural y la riqueza de especies favorecieron la caída de hojarasca, mientras que las condiciones químicas del suelo influyeron en el retorno de nutrientes y descomposición. Conclusiones: Los BSTs tienen la capacidad de recuperar la función ecosistémica de aporte de hojarasca fina, retorno y liberación de nutrientes después del cese de alteraciones antrópicas; sin embargo, la calidad del suelo es fundamental en el retorno y liberación de nutrientes.

Introducción. La acelerada transición nutricional en Latinoamérica ha modificado los patrones alimentarios, favoreciendo dietas con mayor participación de productos industrializados y alto aporte de nutrientes relacionados con enfermedades crónicas como grasas (saturadas, trans), sodio, azúcar libre y densidad de energía. Objetivo. Describir los momentos alimentarios de consumo de productos comestibles ultraprocesados (PCUP) durante el día en Antioquia, Colombia. Materiales y métodos. Estudio descriptivo transversal, usando datos de consumo de alimentos del Perfil Alimentario y Nutricional de Antioquia 2019 y del Perfil de Seguridad Alimentaria y Nutricional de Medellín 2015, en población general, muestra de 13494 individuos. Los alimentos se clasificaron según NOVA y se agruparon en subcategorías. Se calculó la media de energía consumida y su desviación estándar (confianza del 95%) para las categorías NOVA y subcategorías, además su distribución en los momentos alimentarios. Resultados. Para la población de Medellín (capital de Antioquia), en promedio el 54,7% de la energía venia de alimentos no procesados, 17,3% de ingredientes culinarios, y 20,4% de PCUP. En la población de Antioquia, 56,0% de la energía se obtuvo de alimentos no procesados, 18,8% de ingredientes culinarios y 17,0% de PCUP. En los momentos alimentarios principales (desayuno, almuerzo y cena) los alimentos no procesados tienen mayor aporte energético. Mientras que los momentos alimentarios con mayor porcentaje de energía proveniente de PCUP fueron la media mañana, el algo y la merienda. Conclusiones. Para los antioqueños el mayor riesgo de consumo de PCUP relacionados con la obesidad y las enfermedades crónicas se presenta entremedio de las comidas principales(AU)


Introduction. The accelerated nutritional transition in Latin America has modified dietary patterns, favoring diets with a greater participation of industrialized products and a high contribution of nutrients related to chronic diseases such as fats (saturated, trans), sodium, free sugar, and energy density. Objective. To describe the dietary moments of consumption of ultra-processed foods (UPF) during the day in Antioquia, Colombia. Materials and methods. Cross-sectional descriptive study using food consumption data from the Food and Nutrition Profile of Antioquia 2019 and the Food and Nutrition Security Profile of Medellín 2015, in general population, sample of 13,494 individuals. Foods were classified according to NOVA and grouped into subcategories. The mean energy consumed and its standard deviation (95% confidence), were calculated for the NOVA categories and subcategories, as well as its distribution at feeding times. Results. for the population of Medellín (capital of Antioquia), on average 54.7% of the energy came from unprocessed foods, 17.3% from culinary ingredients, and 20.4% from UPF. In the population of Antioquia, 56.0% of the energy was obtained from unprocessed foods, 18.8% from culinary ingredients, and 17.0% from UPF. At the main eating moments (breakfast, lunch, and dinner) unprocessed foods have a greater energy contribution. While the food moments with the highest percentage of energy coming from UPF were mid-morning snacks and snacks. Conclusions. For Antioqueños the greatest risk of consuming UPFs related to obesity and chronic diseases occurs between main meals(AU)

Résumé

Resumen Introducción: en la actualidad se recomienda limitar el consumo de productos ultraprocesados por su alto contenido en azúcar, grasas totales, grasas saturadas, grasas trans y sodio. El etiquetado frontal es una estrategia destinada a fortalecer en el consumidor su capacidad de elegir, pero la estrategia de adición de micronutrientes realizada por la industria alimentaria contribuye a que los consumidores sobrestimen su calidad nutricional. El objetivo de este estudio fue analizar según el modelo del Perfil de Nutrientes (PN) de la Organización Panamericana de la Salud (OPS), un grupo de productos ultraprocesados disponibles en el mercado argentino y aplicar el modelo de forma diferenciada en productos fortificados por la industria alimentaria. Materiales y método: estudio de campo, transversal, descriptivo. Se aplicó el perfil de nutrientes considerando: azúcares libres, grasas totales, grasas saturadas, grasas trans y sodio, en productos fortificados y sin fortificación. Cada una de las categorías generales de alimentos: galletitas dulces, alfajores, chocolates, golosinas, helados, cereales, bebidas, dulces untables, snacks salados y lácteos, fueron divididas en subcategorías, integradas por diferentes productos. Se realizó un análisis estadístico descriptivo por subcategorías. Resultados: la muestra se conformó por 682 productos y todos superaron el punto de corte de al menos un nutriente en cantidad excesiva. El 100% de los productos fortificados (n=146) presentó cantidad excesiva de algún nutriente, el 41,1% tuvo un nutriente en cantidad excesiva y el 50,7% dos nutrientes. 95,7-100% de los productos de los grupos cereales de desayuno, chocolatadas, yogures bebibles y en pote, se categorizaron como con cantidad excesiva de azúcares libres. Conclusiones: todos los productos analizados presentaron al menos un nutriente del PN de referencia, en cantidad excesiva. Los mismos productos tenían adición de vitaminas, minerales o fibra. Se visibiliza la necesidad de realizar estudios que investiguen si esta estrategia induce confusión en el consumidor al momento de elegir.


Abstract Introduction: it is currently recommended to limit the consumption of ultra-processed products because of their high content of sugar, total fats, saturated fats, trans fats and sodium. Front labelling is a strategy aimed at strengthening consumer choice, but the micronutrient addition strategy carried out by the food industry contributes to consumers overestimating their nutritional quality. The objective of this study was to analyze, following the model of the Nutrient Profile (PN) of the Pan American Health Organization (PAHO), a group of ultra-processed products available in the Argentine market and apply the model in a differentiated way in products fortified by the food industry. Materials and method: field study, cross-sectional, descriptive. The nutrient profile was applied considering: free sugars, total fats, saturated fats, trans fats and sodium, both in fortified and unfortified products. Each of the general food categories: sweet cookies, alfajores, chocolates, sweets, ice cream, cereals, beverages, spreadable sweets, salty snacks and dairy products, were divided into subcategories, made up of different products. A descriptive statistical analysis by subcategories was performed. Results: the sample consisted of 682 products and all exceeded the cut-off point of at least one nutrient in excessive quantity. 100% of the fortified products (n=146) had an excessive amount of some nutrient, 41.1% had an excess nutrient and 50.7% two nutrients. 95.7-100% of the products of the breakfast cereals, chocolate, drinking and potted yogurts groups were categorized as having excessive amounts of free sugars. Conclusions: all the products analyzed presented at least one nutrient from the reference NP, in excessive quantity. The same products had added vitamins, minerals or fiber. The need for studies to research whether this strategy induces confusion in the consumer when choosing is made visible.

Résumé

Una de las formas de estudiar patrones alimentarios es a través de Índices de Calidad de Dieta, algunos de los cuales se basan en la densidad nutricional de los alimentos. El concepto resume en una medida la relación entre energía y nutrientes a promover y a limitar, visibilizando las adecuaciones de nutrientes en forma paralela al equilibrio energético. El objetivo del trabajo es estudiar la calidad de dieta y sus brechas en una muestra de la población urbana de Argentina y describir la conformación del patrón alimentario según niveles de calidad nutricional utilizando el enfoque de densidad nutricional. Métodos: Se analizaron los datos de una encuesta alimentaria por autorregistro sobre 1030 sujetos de 11 ciudades de Argentina. Partiendo de sus consumos alimentarios se determinó la densidad nutricional a través de un índice (IDN) basado en energía, 9 nutrientes a promover y 4 a limitar. Se analizó el IDN de la dieta total, de 5 momentos de ingesta y de grupos de alimentos. Resultados: La calidad de dieta promedio alcanzó la mitad del estándar de un patrón saludable (10,6 sobre 20 puntos). Los mejores resultados se concentraron en menores de 3 años (17% presentaron una buena calidad de dieta). Comparados con el estándar, la calidad de almuerzos y cenas superaron a desayunos y meriendas. Legumbres, hortalizas, frutas y lácteos fueron los grupos con mayores brechas de calidad. Alimentos ocasionales y feculentos en general ­también carnes­ reflejaron excesos. Preparaciones y comidas rápidas alcanzaron hasta un 21 % de la densidad nutricional total. Conclusiones: El enfoque de densidad nutricional complementa la comprensión de las brechas alimentarias en la población argentina, al aportar argumentos en favor de intervenciones orientadas a un mejor equilibrio en particular en alimentos protectores, deficitarios en la conformación del patrón alimentario


Diet Quality Index represents one way to study food patterns. Some of them are based on the nutritional density of foods. The concept summarizes the relationship between energy and nutrients to promote and limit, making visible nutrient adequacy in line with energy balance. The objective is to study the quality of the diet and its gaps in a sample of the urban population of Argentina and to describe the food pattern according to levels of nutritional quality using the nutritional density approach. Methods: Data from a self-registration dietary survey on 1030 subjects from 11 cities in Argentina were analyzed. It was determined the nutritional density of the reported consumptions through an index (IDN) based on energy, 9 nutrients to promote and 4 to limit. The IDN of the total diet, 5 moments of intake and food groups was analyzed. Results: The average diet quality was half the standard of a healthy pattern (10.6 out of 20 points). The best results were concentrated in children under 3 years of age (17% presented a good quality diet). Compared to the standard, the quality of lunches and dinners exceeded breakfasts and snacks. Legumes, vegetables, fruits and dairy products were the groups with the largest quality gaps. Occasional and starchy foods in general ­also meats­ reflected excesses. Preparations and fast meals reached up to 21% of the total nutritional density. Conclusions: The nutritional density approach complements the understanding of food gaps in the Argentine population, providing arguments in favor of interventions aimed at a better balance, particularly in protective foods, which are deficient in the conformation of the food pattern

Las barras de cereal (BC), se comercializan como un snack saludable, no obstante, su calidad nutricional es baja. Una alternativa para mejorar esto, es la incorporación de ingredientes como pseudocereales, germinados y subproductos de fruta. Objetivo. Evaluar el contenido nutricional y propiedades tecnofuncionales de una barra de cereal formulada a partir de pseudocereales, germinados de soya y subproductos del procesamiento de frutas. Materiales y Métodos. Se desarrollaron 6 formulaciones (F0-F5). Se determinó el contenido de proteína y fibra cruda, se seleccionó la formulación que presentó el mayor contenido de estos componentes. A la BC seleccionada se le determinó la digestibilidad in-vitro de la proteína, las propiedades tecnofuncionales potencial prebiótico y actividad inhibitoria de ECA-I. Resultados. La formulación seleccionada fue F1 (13,6 g/100 g p.s. proteína y 13,1 g/100 g p.s. fibra cruda). La digestibilidad de la proteína fue del 69 %, el cual es cercano a valores reportados para algunos componentes de la BC. La capacidad de hinchamiento y retención de agua fue 2,55 ml/g; 12,74 %, respectivamente. El crecimiento de L. brevis en medio MRS modificado con BC no presentó diferencias estadísticas con el medio control, indicando el potencial prebiótico presente en la BC. La barra de cereal tuvo un 39% de actividad inhibitoria de ECA-I, demostrando la acción de los compuestos bioactivos posiblemente liberados durante la digestión de la BC. Conclusión. La formulación desarrollada presenta propiedades funcionales importantes y podría generar beneficios para la salud(AU)


Introduction. Cereal bars (CB) are marketed as a healthy snack; however, their nutritional quality is low. An alternative to improve this is the incorporation of ingredients such as soybean sprouts, which have a higher protein content than some seeds; as well as fruit by-products that contain important bioactive compounds. Objective. To evaluate the nutritional content and techno-functional properties of a cereal bar formulated from pseudocereals, soybean sprouts, and fruit processing by-products. Materials and Methods. 6 formulations (F0-F5) were developed. The content of protein and crude fiber was determined, the formulation that presented the highest content of these components was selected. The in-vitro digestibility of the protein, the technofunctional properties, potential prebiotic and inhibitory activity of ACE-I were determined for the selected BC. Results. The selected formulation was F1 (13.6g/100g p.s. protein and 13.1g/100 g p.s. crude fiber). Protein digestibility was 69%, which is close to reported values for some CB components. The swelling and water retention capacity was 2.55 ml/g; 12.74%, respectively. The growth of L. brevis in modified MRS medium with CB did not present statistical differences with the control medium, indicating the prebiotic potential present in CB. The cereal bar had 39% ACE-I inhibitory activity, demonstrating the action of bioactive compounds possibly released during CB digestion. Conclusion. The developed formulation has important functional properties and could generate health benefits(AU)

Résumé

Estudos recentes evidenciam que a ansiedade é conceituada como o mal do século. De acordo com a Organização Mundial da Saúde (OMS), 18,6 milhões de brasileiros sofrem com algum distúrbio relacionado à ansiedade. A fisiopatologia da doença tem relação com a disfunção de neurotransmissores, tornando extremamente necessário o estudo dos neurotransmissores que auxiliam no combate ao transtorno da ansiedade. Realizou-se uma revisão bibliográfica sistemática observacional retrospectiva baseada em artigos científicos coletados nas bases de dados Scielo, Google Acadêmico e Biblioteca Virtual em Saúde (BVS). Uma alimentação balanceada e rica em micronutrientes fornece aos neurônios os nutrientes essenciais para a produção dos neurotransmissores responsáveis pela transmissão de mensagens cognitivas, incluindo sentimentos, emoções e pensamentos do indivíduo, podendo auxiliar significativamente na melhora do quadro de ansiedade. Os estudos levantados associam a correta ingestão de nutrientes como triptofano, vitamina D e ômega-3 como eficaz auxílio no tratamento da ansiedade. O objetivo do presente estudo é descrever a relação e eficácia do fator alimentação no tratamento do transtorno da ansiedade.

Résumé

Atherosclerosis(AS) is caused by impaired lipid metabolism, which deposits lipids in the intima, causes vascular fibrosis and calcification, and then leads to stiffening of the vascular wall. Hyperlipidemia(HLP) is one of the key risk factors for AS. Based on the theory of "nutrients return to the heart and fat accumulates in the channels", it is believed that the excess fat returning to the heart in the vessels is the key pathogenic factor of AS. The accumulation of fat in the vessels over time and the blood stasis are the pathological mechanisms leading to the development of HLP and AS, and "turbid phlegm and fat" and "blood stasis" are the pathological products of the progression of HLP into AS. Didang Decoction(DDD) is a potent prescription effective in activating blood circulation, removing blood stasis, resolving turbidity, lowering lipids, and dredging blood vessels, with the functions of dispelling stasis to promote regeneration, which has certain effects in the treatment of atherosclerotic diseases. This study employed high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(HPLC-Q-TOF-MS/MS) to screen the main blood components of DDD, explored the targets and mechanisms of DDD against AS and HLP with network pharmacology, and verified the network pharmacological results by in vitro experiments. A total of 231 blood components of DDD were obtained, including 157 compounds with a composite score >60. There were 903 predicted targets obtained from SwissTargetPrediction and 279 disease targets from GeneCards, OMIM, and DisGeNET, and 79 potential target genes of DDD against AS and HLP were obtained by intersection. Gene Ontology(GO) analysis suggested that DDD presumably exerted regulation through biological processes such as cholesterol metabolism and inflammatory response, and Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis suggested that signaling pathways included lipid and atherosclerosis, insulin resistance, chemo-carcinogenesis-receptor activation, and AGE-RAGE signaling pathways in diabetic complications. In vitro experiments showed that DDD could reduce free fatty acid-induced lipid accumulation and cholesterol ester content in L02 cells and improve cellular activity, which might be related to the up-regulation of the expression of PPARα, LPL, PPARG, VEGFA, CETP, CYP1A1, and CYP3A4, and the down-regulation of the expression of TNF-α and IL-6. DDD may play a role in preventing and treating AS and HLP by improving lipid metabolism and inflammatory response, and inhibiting apoptosis with multi-component, multi-target, and multi-pathway characteristics.

Résumé

Objective: To explore the relationship between nutrient-related dietary pattern and mild cognitive impairment (MCI) in middle-aged and elderly people. Methods: A total of 6 444 middle-aged and elderly people aged ≥55 years were selected in 2018 China Health and Nutrition Survey. MCI was evaluated by Mini-Mental State Examination, and the intakes of various foods were obtained by consecutive 3-day 24-hour dietary survey and weighing method. The intakes of various nutrients and total dietary energy were calculated based on the food composition table. Demographic and social information, lifestyle and health status of the respondents were obtained through questionnaire survey and physical measurements. In this study, vitamin C, vitamin E, zinc, iron, copper and selenium were selected as dependent variables. Nutrient-related dietary patterns were extracted by reduced rank regression method, and the relationship between dietary patterns and MCI was analyzed by multivariate logistic regression model. Results: Six dietary patterns were extracted in this study, and dietary pattern 1 with the highest explanatory degree was selected for subsequent analysis. Dietary pattern 1 was characterized by higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products and plant oil. Multivariate logistic regression analysis showed that the risk of MCI was lower in Q4 dietary score group than in Q1 dietary score group (OR=0.69, 95%CI: 0.49-0.98) in the 55-64 age group. In people with sleep duration of 8 hours per day, the risk of MCI was reduced in Q2, Q3 and Q4 dietary score groups compared with the Q1 dietary score group, with OR values of 0.68 (95%CI: 0.51-0.92), 0.67 (95%CI: 0.49-0.92) and 0.65 (95%CI: 0.45-0.92), respectively. Interaction analysis showed that the risk for MCI increased in those aged 65-74 years and ≥75 years compared with those aged 55-64 years in Q1 dietary score group. However, the risk for MCI decreased in both age groups as dietary pattern scores increased. Compared with those with sleep duration less or more than 8 hours per day in Q1 dietary score group, those with sleep duration of 8 hours per day in Q2 and Q3 dietary score groups had a reduced risk for MCI. Conclusion: Dietary patterns with higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products, and plant oil are negatively associated with MCI in people aged 55-64 years and those who slept 8 hours per day, and may reduce the risk of MCI with aging.

Résumé

Moutan Cortex(MC) residues produced after the extraction of MC can be re-extracted for active components and used to produce organic fertilizer and animal feed. However, they are currently disposed as domestic waste, which pollutes the environment. This study analyzed the chemical composition of the medicinal material, residues, and residue compost of MC by UPLC-UV-Q-TOF-MS. Furthermore, the nutrient composition of MC residues and the residue compost was analyzed. The results showed that:(1)MC residues had lower content of chemicals than the medicinal material, and content of paeonol, gallic acid, and galloylglucose in MC residues were about 1/3 of that in the medicinal material. The content of chemicals were further reduced after residue composting, and the quantitative compounds were all below the limits of detection.(2)Compared with MC residues, the residue compost showed the total nitrogen, total phosphorus, total potassium, and organic matter content increasing by 122.67%, 31.32%, 120.39%, and 32.06%, respectively. Therefore, we concluded that the MC residues can be used to re-extract active compounds such as paeonol, gallic acid, and galloylglucose. The MC residue compost is a high-quality organic fertilizer containing minimal content of chemicals and can be widely used in the cultivation of Chinese medicinal herbs.

Résumé

Introdução: O leite materno é o alimento ideal para o recém-nascido a termo e prétermo e sua composição varia de acordo com vários fatores que podem ser maternos, ambientais e até mesmo genéticos. Pode ser ordenhado através da expressão manual ou com auxílio de bomba (elétrica ou manual). Ainda não está claro na literatura o efeito das diferentes técnicas de ordenha na composição dos macronutrientes. Desta forma, o conhecimento das técnicas de extração do leite materno mais eficazes, no sentido de favorecer uma maior concentração de nutrientes, torna-se essencial para enriquecer uma recomendação que oriente essa ordenha em mães de recém-nascidos pré-termo durante o período de internação. Objetivos: Analisar a diferença na concentração de macronutrientes de leite das mães de recém-nascidos de acordo com a técnica de extração do leite (técnica de ordenha manual e através de bomba elétrica). Metodologia: Foi realizado um ensaio clínico randomizado crossover com 32 mães de recém-nascidos pré-termo internados na Unidade Neonatal do Instituto Nacional de Saúde da Mulher, da Criança e do Adolescente Fernandes Figueira (IFF/Fiocruz). Foram avaliadas 248 amostras de leite humano cru extraídos por bomba elétrica e por ordenha manual para avaliação dos macronutrientes energéticos (proteínas, gorduras e carboidratos) utilizando o Human Milk Analyzer ­ MIRIS nas fases de colostro, leite transição e leite maduro. Resultados: Não observamos diferenças estatisticamente significativas entre a mama direita e esquerda na extração por bomba e extração manual, porém houve diferença na composição dos macronutrientes. No colostro, observamos maior concentração de carboidrato na extração manual; no leite de transição a concentração de gordura e valor energético total foi maior na extração manual e no leite maduro, as concentrações de proteína e carboidrato foram maiores na extração por bomba elétrica. Conclusão: Observamos diferenças na composição de macronutrientes em todas as fases do leite humano dependendo da forma de extração. Esse resultado pode nortear as recomendações para as mães de recém-nascidos pré-termo internados na unidade neonatal, a fim de proporcionar um aporte nutricional mais próximo ao ideal.


Introduction: Breast milk is the ideal food for full-term and preterm newborns and its composition varies according to several factors that may be maternal, environmental and even genetic. It can be milked through manual expression or with the aid of a pump (electric or manual). The effect of different milking techniques on the composition of macronutrients is still unclear in the literature. In this way, knowledge of the most effective breast milk extraction techniques, in order to favor a greater concentration of nutrients, becomes essential to enrich a recommendation that guides this expression in mothers of preterm newborns during the period of hospitalization. Objectives: To analyze the difference in the concentration of macronutrients in the milk of mothers of newborns according to the milk extraction technique (manual milking technique and using an electric pump). Methodology: A randomized crossover clinical trial was carried out with 32 mothers of preterm newborns admitted to the Neonatal Unit of the Fernandes Figueira National Institute of Women, Children and Adolescent Health (IFF/Fiocruz). 248 samples of raw human milk extracted by electric pump and manual milking were evaluated to evaluate energy macronutrients (proteins, fats and carbohydrates) using the Human Milk Analyzer ­ MIRIS in the colostrum, transition milk and mature milk phases. Results: We did not observe statistically significant differences between the right and left breasts in pump extraction and manual extraction, however there was a difference in the composition of macronutrients. In colostrum, we observed a higher carbohydrate concentration in manual extraction; In transitional milk, the fat concentration and total energy value were higher in manual extraction and in mature milk, protein and carbohydrate concentrations were higher in electric pump extraction. Conclusion: We observed differences in the composition of macronutrients in all phases of human milk depending on the form of extraction. This result can guide recommendations for mothers of preterm newborns admitted to the neonatal unit, in order to provide nutritional support closer to ideal.

Résumé

Abstract Fishmeal; being a limited and costly feed ingredient is continuously been substituted with locally available plant proteins. However, the occurrence of anti-nutritional factors in plant meal suppresses its potential to be fully replaced. Therefore, in this study we aimed to study the synergistic effects of dietary additives like citric acid and phytase enzyme supplementation on growth performance and nutrient digestibility of Cirrhinus mrigala fingerlings. Canola meal (CM) was used as a test ingredient to replace fishmeal (FM) as; 0%, 25%, 50% and 75%. These four diets were further supplemented by varying levels of phytase (0 and 750 FTU kg-1) and citric acid (0% and 2.5%) to formulate total sixteen test diets as T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15 and T16. Each treatment contained three replicates; applied to fish groups having 15 fingerlings each; following 3×3 factorial arrangement. 1% of chromic oxide was added as an inert marker. Maximum weight gain% (288%) and the lowest value of FCR (1.07) were recorded when fish was fed on diet T12 as compared to fish fed control diet (T1). Similarly, optimum nutrient digestibility values such as crude protein (77%), crude fat (84%) and gross energy (70%) were noted on same level. It was concluded that 50% canola meal can optimally replace fishmeal when supplemented with phytase and citric acid at the levels of 750 FTU kg-1 and 2.5%, respectively.


Resumo A farinha de peixe, por ser um ingrediente alimentar limitado e caro, é continuamente substituída por proteínas vegetais disponíveis localmente. No entanto, a ocorrência de fatores antinutricionais na farinha de plantas suprime seu potencial de ser totalmente substituída. Portanto, neste estudo objetivamos estudar os efeitos sinérgicos de aditivos dietéticos como ácido cítrico e suplementação com enzima fitase sobre o desempenho de crescimento e digestibilidade de nutrientes de alevinos de Cirrhinus mrigala. A farinha de canola (CM) foi usada como ingrediente de teste para substituir a farinha de peixe (FM) como: 0%, 25%, 50% e 75%. Essas quatro dietas foram suplementadas por níveis variados de fitase (0 e 750 FTU kg-1) e ácido cítrico (0% e 2,5%) para formular um total de 16 dietas de teste como T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15 e T16. Cada tratamento continha três repetições; aplicado a grupos de peixes com 15 alevinos cada; seguindo o arranjo fatorial 3 × 3. 1% de óxido crômico foi adicionado como um marcador inerte. % de ganho de peso máximo (288%) e o valor mais baixo de FCR (1,07) foram registrados quando os peixes foram alimentados com dieta T12 em comparação com peixes alimentados com dieta controle (T1). Da mesma forma, valores ótimos de digestibilidade de nutrientes, como proteína bruta (77%), gordura bruta (84%) e energia bruta (70%) foram anotados no mesmo nível. Concluiu-se que 50% da farinha de canola pode substituir de forma ideal a farinha de peixe quando suplementada com fitase e ácido cítrico nos níveis de 750 FTU kg-1 e 2,5%, respectivamente.

Résumé

Abstract Introduction: Fine root dynamics include production, turnover and decomposition; they are crucial to forest health, affect the entire biogeochemical complex of the ecosystem, and consequently, they substantially affect carbon balance. However, the influence of environmental factors and soil nutrient limitation on fine roots presents considerable uncertainties and has not been studied in tropical forests with more than 7 000 mm annual rainfall. Objective: To measure the effect of fertilization on fine roots in the high precipitation Chocó forest. Methods: We worked in two sites of the Chocó region, Colombia (August 2014-May 2015), where rainfall exceeds 10 000 mm per year. We applied five fertilization treatments (N, P, K, NPK and Control) to two soil type plots. Soil cylinders were removed at pre-established intervals to measure roots. Results: Phosphorus applications increased fined roots; and more fine roots were produced in sandy than in loam soil. The effects of fertilization were related, but not clearly determined by edaphic conditions. Conclusions: In this Chocó forest, the production of fine roots was higher in sandy and nutrient-rich soils but belowground net primary productivity was limited by the content of edaphic Phosphorus.


Resumen Introducción: La dinámica de las raíces finas incluye producción, rotación y descomposición; son cruciales para la salud de los bosques, afectan todo el complejo biogeoquímico del ecosistema y, en consecuencia, afectan sustancialmente el balance de carbono. Sin embargo, la influencia de los factores ambientales y la limitación de nutrientes del suelo en las raíces finas presenta incertidumbres considerables y no se ha estudiado en bosques tropicales con más de 7 000 mm de precipitación anual. Objetivo: Medir el efecto de la fertilización en las raíces finas en el bosque chocoano de alta precipitación. Métodos: Se trabajó en dos sitios de la región del Chocó, Colombia (agosto 2014-mayo 2015), donde las precipitaciones superan los 10 000 mm anuales. Se aplicaron cinco tratamientos de fertilización (N, P, K, NPK y Control) a dos parcelas por tipo de suelo. Los cilindros de suelo se retiraron a intervalos preestablecidos para medir las raíces. Resultados: Las aplicaciones de fósforo aumentaron las raíces finas; y se produjeron más raíces finas en suelos arenosos que en francos. Los efectos de la fertilización estuvieron relacionados, pero no claramente determinados por las condiciones edáficas. Conclusiones: En este bosque chocoano, la producción de raíces finas fue mayor en suelos arenosos y ricos en nutrientes, pero la productividad primaria neta subterránea estuvo limitada por el contenido de fósforo edáfico.
