ABSTRACT

Aim: To propose a new method to determine in vitro potentially bioavailable fluoride (F) in diet and toothpaste after ingestion. Methods: Diet samples (D) were obtained from 15 portions of a meal served to children in a day care centre. To simulate the ingestion of toothpaste during brushing after meals, a specific amount of toothpaste was added to the diet samples (D + T). F was determined in D and D + T after incubation in a solution that simulated "gastric juice" (0.01 M hydrochloric acid) at 37oC for 30, 60 and 120 min. Microdiffusion facilitated by HMDS was used to determine the total F concentrations in samples D and D + T. The analyses were performed using an ion specific electrode. Results: For D samples, incubation in "gastric juice" for 30, 60 and 120 min resulted in F concentrations (µg F/mL) of 0.75 ± 0.06c, 0.77 ± 0.07c and 0.91 ± 0.09b, corresponding to 75.3, 77.3 and 90.7% of the total F (1.02 ± 0.12a), respectively (p = 0.0001; ANOVA + Tukey). For D + T samples, these values of F concentrations (µg F/mL) were 2.55 ± 0.46b, 2.83 ± 0.44ab and 3.15 ± 0.37a, corresponding to 86.9, 94.8 and 106.7% of the total F (2.99 ± 0.34a), respectively (p = 0.0023; ANOVA + Tukey). Conclusion: Then, it can be concluded that the proposed method of "gastric juice" is a promising protocol for determining potentially bioavailable fluoride in the diet and toothpaste after ingestion. However, additional studies are desirable

ABSTRACT

Resumo O objetivo deste artigo é analisar a relação entre duração insuficiente do sono, sobrepeso/obesidade e o consumo de alimentos ultraprocessados em adolescentes de 10 a 14 anos. Trata-se de um estudo transversal, com avaliação de 1.384 adolescentes de escolas públicas de João Pessoa-PB, participantes do Estudo Longitudinal sobre Comportamento Sedentário, Atividade Física, Hábitos Alimentares e Saúde de Adolescentes (LONCAAFS). Foram mensuradas variáveis sociodemográficas, duração do sono, turno de aula, estado nutricional antropométrico, comportamento sedentário e consumo alimentar. Foram realizadas regressão linear e logística por meio do Software Stata 13.0. Prevalência de curta duração do sono de 29,5% (<9h/noite). Associação significativa entre a curta duração do sono e o excesso de peso somente para adolescentes <12 anos. Quanto à relação entre a duração do sono e o consumo de alimentos ultraprocessados, quanto maior a duração do sono, menor o consumo de lanches pelos adolescentes menores de 12 anos, com associação positiva para ≥12 anos apenas com ajuste pela variável atividade física. Não houve associação com os grupos "bebidas açucaradas" e "biscoitos" para nenhuma das faixas etárias analisadas.


Abstract The scope of this article is to analyze the relationship between insufficient sleep duration, overweight/obesity and the consumption of ultra-processed foods among adolescents aged 10 to 14 years. This is a cross-sectional study, with an evaluation of 1,384 adolescents from public schools in João Pessoa-PB, participating in the Longitudinal Study on Sedentary Behavior, Physical Activity, Diet and Adolescent Health (LONCAAFS). Sociodemographic variables, sleep duration, class shift, anthropometric nutritional status, sedentary behavior and food consumption were measured. Linear and logistic regression of the following were performed using Stata 13.0 Software: the prevalence of short sleep duration of 29.5% (<9h/night); a significant association between short sleep duration and excess weight only for adolescents <12 years old. With respect to the relationship between sleep duration and the consumption of ultra-processed foods, the longer the sleep duration, the lower the consumption of snacks by adolescents under 12 years old, with a positive association for ≥12 years old only with adjustment by the physical activity variable. There was no association with the "sugary drinks" and "cookies" groups for any of the age groups analyzed.

ABSTRACT

Muitos são os problemas orgânicos ou psíquicos que surgem em indivíduos obesos. Diante desse mal-estar gerado pela obesidade, as angústias são relatadas com frequência por pacientes em discursos que giram em torno da alimentação e do corpo, carregados de frustrações que remetem a dietas fracassadas para dar conta da supervalorização de um corpo ideal na sociedade contemporânea. Nesse sentido, foi percebido nos relatos clínicos uma repetição, um ciclo vicioso que os pacientes têm dificuldade de interromper. Grande parte desses sujeitos relataram, nos atendimentos em grupo e individuais, que têm a comida como substituto de "algo", de um "vazio" que precisa ser preenchido, pois comem mesmo sem estarem com fome e com uma sensação de perda do controle sobre o ato. Por essa razão, após esse comportamento repetitivo, têm sentimentos de raiva, vergonha e culpa. Este artigo tem por objetivo investigar o mal-estar observado nas pessoas obesas atendidas individualmente na clínica particular e na instituição privada, bem como nos atendimentos realizados em grupo. Busca-se conhecimentos acerca da angústia em relação ao corpo obeso, com vistas a fomentar discussões embasadas pela orientação psicanalítica, utilizando durante os atendimentos a metodologia freudiana e a balintiana no atendimento de grupo.


Many are the organic or psychic problems that arise in obese individuals. Faced with this discomfort generated by obesity, anxieties are frequently reported by patients in discourses that revolve around diet and the body, loaded with frustrations that refer to failed diets to cope with the overvaluation of an ideal body in contemporary society. In this sense, it was perceived in clinical reports a repetition, a vicious cycle that patients have difficulty interrupting. Most of these subjects reported, in group and individual care, that they have food as a substitute for "something", a "void" that needs to be filled, because they eat even without being hungry and with a sense of loss of control over the act. For this reason, after this repetitive behavior, they have feelings of anger, shame and guilt. This article aims to investigate the discomfort observed in obese people treated individually in the private clinic and private institution, as well as in group care. Knowledge about anguish in relation to the obese body is sought, in order to foster discussions based on psychoanalytic orientation, using the Freudian and Balintian methodology during group care


Muchos son los problemas orgánicos o psíquicos que surgen en personas obesas. Frente a este malestar generado por la obesidad, los pacientes informan con frecuencia ansiedades en discursos que giran en torno a la dieta y el cuerpo, cargados de frustraciones que conducen a dietas fallidas para hacer frente a la sobrevaloración de un cuerpo ideal en la sociedad contemporánea. En este sentido, se percibió en los informes clínicos una repetición, un círculo vicioso que los pacientes tienen dificultades para interrumpir. La mayoría de estos sujetos informaron, en atención grupal e individual, que tienen comida como un sustituto de "algo", un "vacío" que necesita ser llenado, porque comen incluso sin tener hambre y con una sensación de pérdida de control sobre el acto Por esta razón, después de este comportamiento repetitivo, tienen sentimientos de ira, vergüenza y culpa. Este artículo tiene como objetivo investigar las molestias observadas en personas obesas tratadas individualmente en la clínica privada y la institución privada, así como en la atención grupal. Buscamos conocimiento sobre la angustia con respecto al cuerpo obeso, para fomentar discusiones basadas en la orientación psicoanalítica, utilizando durante la metodología freudiana y balintiana en la atención grupal.

ABSTRACT

Resumo O objetivo deste estudo foi caracterizar a quantidade e a variedade de frutas e hortaliças adquiridas nos domicílios brasileiros em 2008-09 e 2017-18 e segundo regiões e classes de rendimento em 2017-18. Foram utilizados dados das Pesquisas de Orçamentos Familiares referentes a disponibilidade domiciliar de frutas e hortaliças. A quantidade anual per capita adquirida de cada item alimentar foi transformada em valores diários. Foram descritas as médias da quantidade absoluta (grama/per capita/dia) e relativa de cada tipo de fruta e hortaliça para o Brasil (nos dois períodos) e segundo regiões e renda (em 2017-18). Verificou-se baixa aquisição de frutas e hortaliças para o Brasil (54,4 g e 42,7 g em 2008-09; 49,7 g e 37,4 g em 2017-18, respectivamente), e em todas as regiões e classes de renda analisadas. O Sul apresentou a maior aquisição e o Norte a menor; a quantidade adquirida aumentou com o aumento da renda. Seis tipos de frutas (banana prata, maçã, banana d'água, laranja pera, melancia e mamão) e três de hortaliças (tomate, cebola e cenoura) representaram mais de 50% da aquisição total no Brasil, sendo semelhante em todos os estratos analisados. A aquisição de frutas e hortaliças no Brasil foi baixa e apresentou pouca variação. Esse cenário se reproduziu em todas as regiões e faixas de renda.


Abstract The objective of this study was to establish the quantity and variety of fruit and vegetables (FV) available in Brazilian households in 2008-09 and 2017-18, and according to regions and income classes in 2017-18. Data from the Household Budget Surveys were used regarding household availability of fruit and vegetables. The annual per capita amount of each food item purchased was transformed into daily amounts. The absolute (gram/per capita/day) and the relative average quantities of each type of FV in Brazil (in both periods), and according to region and income (in 2017-18), were analyzed. An insufficient quantity of fruit and vegetables purchased in Brazil (54.4 g and 42.7 g in 2008-09; 49.7 g and 37.4 g in 2017-18, respectively) in all regions and income classes was verified. The South represented the highest amount purchased, while the North revealed the lowest; the quantity of FV increased as income increased. Six varieties of fruit (banana, apple, plantain, orange, watermelon, and papaya) and three types of vegetables (tomato, onion, and carrot) represented more than 50% of the total acquisition in Brazil, which was similar for all strata analyzed. The acquisition of fruit and vegetables in Brazil was low and featured little variation. This scenario was the same for all regions and income brackets.

ABSTRACT

This research article aims to evaluate the effect of total replacement of corn by soybean meal and urea on intake and apparent digestibility of dry matter and its components, production and composition of milk and feeding behavior of lactating cows grazing, with intermittent stocking Mombaça grass (Megathyrsus maximus cv. Mombaça). Twelve milking cows were distributed in a triple 4 x 4 latin square. Experimental treatments consisted of four soybean meal replacement levels by corn more urea (0; 33; 66; 100%). The grass has an average content of crude protein and neutral detergent fiber of 19% and 59%, respectively. The replacement of soybean meal by corn and urea did not affect the intake and digestibility of nutrients. A linear reduction of milk production was observed, but there was no change in milk production corrected to 4.0% of fat. The milk components (g/kg) of fat, protein, lactose, and total solids were not altered, as well as feeding behavior. Under the conditions of this study, the replacement of the diets is suitable for crossbred dairy cows in lactation third medium, producing in average of 12.5 kg/day-1 when kept in quality pastures.(AU)


Este artigo de pesquisa tem como objetivo avaliar o efeito da substituição total do milho pelo farelo de soja e ureia sobre o consumo e a digestibilidade aparente da matéria seca e de seus componentes, a produção e a composição do leite e o comportamento alimentar de vacas em lactação mantidas em pastos capim-mombaça (Megathyrsus maximus cv. Mombaça) manejado sob lotação intermitente. Doze vacas em lactação foram distribuídas em um quadrado latino triplo 4 x 4. Os tratamentos experimentais consistiram de quatro níveis de substituição do farelo de soja pelo milho mais ureia (0; 33; 66; 100%). O capim-mombaça apresentou um teor médio de proteína bruta e de fibra em detergente neutro de 19% e 59%, respectivamente. A substituição do farelo de soja por milho e ureia não afetou o consumo e a digestibilidade dos nutrientes. Observou-se redução linear da produção de leite, mas não houve alteração na produção de leite corrigida para 4,0% de gordura. Os componentes do leite (g/kg): gordura, proteína, lactose e sólidos totais não foram alterados, assim como o comportamento ingestivo dos animais. Nas condições deste estudo, a substituição total do milho pelo farelo de soja e ureia nas dietas é adequada para vacas mestiças leiteiras em terço médio de lactação, produzindo, em média, 12,5 kg / dia-1 quando mantidas em pastagens de qualidade.(AU)

ABSTRACT

The objective was to evaluate the intake and digestibility of nutrients, ingestive behavior, and performance of goats fed with spineless cactus genotypes resistant to carmine cochineal (Miúda or Orelha de Elefante Mexicana (OEM). Thirty castrated male goats, without defined breed, aged 12 to 14 months, with an average body weight of 19.0±2.8kg, were distributed in a completely randomized design among three treatments (Control - Tifton hay, Miúda, and OEM) and ten replicates; the initial weight was considered as the covariate. The intake of organic matter (OM), neutral detergent fiber (NDF) was highest in the control treatment, while the intake of NFC was higher in the OEM diet. Treatments containing forage cactus showed the highest digestibility of DM, OM, and NFC. The animals fed the control diet spent more time on rumination and total chewing, but the time spent feeding or feeding efficiency, and performance did not differ. The use of spineless cactus genotypes resistant to carmine cochineal (Miúda and Orelha de Elefante Mexicana) in a diet for goats, in the amount of 450g/kg of DM does not interfere with the performance of the animals and improves the digestibility of OM and NFC.(AU)


Objetivou-se com o presente estudo avaliar o consumo e a digestibilidade de nutrientes, o comportamento ingestivo e o desempenho de caprinos alimentados com genótipos de palma forrageira resistentes à cochonilha-carmim (miúda ou orelha-de-elefante-mexicana (OEM). Trinta cabritos machos, castrados, sem raça definida, com idades entre 12 e 14 meses e peso corporal médio de 19,0±2,8kg, foram distribuídos em delineamento inteiramente ao acaso, em três tratamentos (controle - feno de tifton; miúda e OEM) e 10 repetições; o peso inicial foi considerado a covariável. O consumo de matéria orgânica (MO) e de fibra em detergente neutro (FDN) foi maior no tratamento controle; enquanto a ingestão de CNF foi maior na dieta OEM. Tratamentos contendo palma forrageira apresentaram as maiores digestibilidades de MS, MO e CNF. Os animais alimentados com a dieta controle gastaram mais tempo em ruminação e em mastigação total, mas o tempo gasto com alimentação ou a eficiência alimentar e o desempenho não diferiram. A utilização de genótipos de palma forrageira resistentes à cochonilha-carmim (miúda e orelha-de-elefante-mexicana) na dieta de caprinos, na quantidade de 450g/kg de MS, não interfere no desempenho dos animais e melhora a digestibilidade de MO e CNF.(AU)

ABSTRACT

As novas tecnologias da informação e comunicação, aliadas às novas mídias e redes de comunicação, transformaram privacidade em objeto de consumo. O cenário comunicacional medeia o acesso a produtos e serviços digitais com novos parâmetros de hábito alimentar e estilo de vida saudáveis. A visibilidade confere prestígio às postagens no ambiente on-line, legitimando-as. O objetivo deste estudo foi mapear a representatividade de postagens de celebridades e compreender seus significados no campo da Alimentação e Nutrição. O problema central é o efeito mágico de um comportamento saudável em orientações doutrinárias sobre o comer. Analisamos imagens e textos de seis perfis de nutricionistas que se tornaram celebridades no Brasil. As postagens guiam seguidores, reproduzindo modelos de respostas rápidas que prometem a felicidade na ilusão de uma disciplina e do controle de si. As páginas operam como 'oráculos' para uma vida saudável, seguindo uma lógica de comunicação fast thinking, pouco propensa à expressão do pensamento.


New information and communication technologies combined with new media and communication networks have made privacy an object of consumption. The communication scenario mediates access to digital products and services with new parameters of healthy eating habits and lifestyle behaviors. Visibility gives prestige to posts that move through the online environment, legitimizing them. The aim of this study was to map the representativeness of celebrity posts and understand their meanings in the field of Food and Nutrition. The central problem is the magical effect of healthy behavior in doctrinal guidelines on eating. We analyzed images and texts of six profiles of nutritionists who became celebrities in Brazil. Posts guide followers, reproducing rapid response models that promise happiness of the illusion of self-discipline and self-control. The webpages operate as 'oracles' for healthy living, following the logic of a fast thinking communication, not prone to the expression of thought.

ABSTRACT

ABSTRACT BACKGROUND: Diverticulitis is an acute inflammatory process that affects individuals with diverticular disease. Given the sharp increase in the diagnostic rate of such a pathological process, there was also an increased interest in elucidating the possible causes related to the development of this clinical condition. Among the main factors investigated, diet excels, the object of study of this integrative literature review. METHODS: After searching the virtual health library and PubMed databases, five prospective cohort studies were selected that best answered the guiding question: "Is there a relationship between diet and the incidence of diverticulitis?". RESULTS: It was observed that the high intake of red meat and the low intake of dietary fiber were the most strongly associated dietary factors with the incidence of this inflammatory process. CONCLUSION: Therefore, it is evident that choosing healthy eating habits can considerably reduce the incidence of diverticulitis and, consequently, potentially more serious complications directly related to it.


RESUMO CONTEXTO: A diverticulite é um processo inflamatório agudo que afeta indivíduos com doença diverticular. Diante do acentuado aumento da taxa diagnóstica desse processo patológico, também houve o aumento do interesse em elucidar as possíveis causas relacionadas ao desenvolvimento dessa condição clínica. Entre os principais fatores investigados, destaca-se a dieta; objeto de estudo desta revisão integrativa da literatura. MÉTODOS: Após pesquisa nas bases de dados da biblioteca virtual em saúde e PubMed, foram selecionados cinco estudos de coorte prospectivos que melhor responderam à questão norteadora "Há relação entre dieta e incidência de diverticulite?". RESULTADOS E CONCLUSÃO: Observou-se que o alto consumo de carnes vermelhas e o baixo consumo de fibra alimentar são os fatores dietéticos mais fortemente associados à incidência desse processo inflamatório. Fica evidente, portanto, que a escolha de hábitos alimentares saudáveis pode reduzir consideravelmente a incidência de diverticulite e, consequentemente, de possíveis complicações mais graves diretamente relacionadas a ela.

ABSTRACT

Resumen: Existe evidencia epidemiológica en humanos, a partir de estudios de cohortes de grandes poblaciones, de que la dieta ejerce una fuerte influencia en el desarrollo y curso de la enfermedad inflamatoria intestinal (EII). Además, la mayoría de los tratamientos médicos basados en la evidencia para las EII están dirigidos a suprimir la respuesta inmunitaria y conllevan riesgos de efectos secundarios importantes. La evidencia actual ha demostrado varios factores dietéticos que probablemente protejan contra los brotes, como la fibra, el zinc y la vitamina D en ambas formas de EII y una alta proporción de Ácidos grasos poliinsaturados (AGPI) n -3 / n -6 en la dieta en la CU. Otros factores aumentan el riesgo de brotes, son los alimentos que contienen ácido mirístico, las carnes rojas y el azúcar. Esta revisión explorará las interacciones de la dieta y el sistema inmunológico en el contexto de la enfermedad de Crohn (EC) y la colitis ulcerosa (CU), centrándose en el papel de la dieta en la patogénesis, en particular la interacción con el sistema inmunológico del paciente. Al mismo tiempo se analizará el rol de la nutrición médica como intervención terapéutica.


Abstract: There is vast epidemiological evidence based on cohort studies of large populations of humans, that diet exerts a strong influence on the development and outcome of inflammatory bowel disease. Besides, most evidence-based medical therapies for this condition aim to suppress the immune response and entail significant side effects. Current evidence has proved that several diet factors probably protect against outbreaks, as in the case of fibre, zinc and vitamin D in both forms of inflammatory bowel disease and a high proportion of polyunsaturated fatty acids (PUFAs) n -3 / n -6 in the ICU diet. Other foods also impact the outbreak risk, such as those containing myristic acid, red meats and sugar. This review will explore diet interactions and the immune system within the context of Crohn's disease and ulcerative colitis, focusing on the role of diet in the pathogenesis, in particular in terms of its interaction with the patient's immune system. Simultaneously, the role of medical nutrition will be analysed as a therapeutic intervention.


Resumo: Há evidências epidemiológicas em seres humanos de estudos de coorte de grandes populações que a dieta tem uma forte influência no desenvolvimento e no curso da Doença Inflamatória Intestinal (DII). Além disso, a maioria dos tratamentos médicos baseados em evidências para DII têm como objetivo suprimir a resposta imunológica e acarretam riscos de efeitos colaterais significativos. A evidência atual mostrou vários fatores dietéticos que provavelmente protegem contra surtos, como fibra, zinco e vitamina D em ambas as formas de DII e uma alta proporção de ácidos graxos poliinsaturados (PUFAs) n -3 / n -6 na dieta na colite ulcerativa (UC). Outros fatores que aumentam o risco de surtos são os alimentos que contêm ácido mirístico, a carne vermelha e o açúcar. Esta revisão explora as interações da dieta e do sistema imunológico no contexto da Doença de Crohn (DC) e da Colite Ulcerativa (UC), com foco no papel da dieta na patogênese, em particular na interação com o sistema imunológico do paciente. Ao mesmo tempo, faz-se uma análise do papel da nutrição médica como intervenção terapêutica.

ABSTRACT

Introducción. La dieta actual de la población se caracteriza por la sustitución de alimentos naturales por productos alimenticios procesados, formulados industrialmente con ingredientes que contienen sodio. Objetivo. Clasificar el contenido de sodio en productos alimenticios preenvasados comercializados en El Salvador, según el perfil de nutrientes de la Organización Panamericana de la Salud y las metas regionales para formulación industrial. Metodología. Diseño transversal descriptivo, se analizaron las etiquetas nutricionales de 1016 productos de siete categorías, registrados en el Sistema de Información en Salud Ambiental. Para la clasificación del contenido de sodio se aplicaron fórmulas según el perfil de nutrientes: alto en sodio ≥1 miligramo de sodio por caloría. Para la clasificación según metas regionales: cuando el contenido de sodio en 100 gramos de producto es > a la meta establecida. Resultados. Según el perfil de nutrientes, el 52% de los productos tiene alto contenido de sodio. Según metas regionales, el 24% está formulado por arriba de las metas, esto refleja diferencias entre las valoraciones de contenido de sodio por categoría. Conclusión. Más de la mitad los productos alimenticios preenvasados comercializados en El Salvador son clasificados como altos en sodio, según el perfil de nutrientes. Una cuarta parte de estos están formulados con sodio por encima de las metas regionales, mostrando que las metas son más flexibles en la valoración de contenido máximo de sodio para la formulación industrial en relación con la valoración de contenido alto en sodio para consumo humano


Introduction. The current diet of the population is characterized by the substitution of natural foods for processed food products, industrially formulated with ingredients that contain sodium. Target. Classify the sodium content in prepackaged food products marketed in El Salvador, according to the nutrient profile of the Pan American Health Organization and the regional goals for industrial formulation. Methodology. Descriptive cross-sectional design, the nutritional labels of 1016 products from seven categories, registered in the Environmental Health Information System, were analyzed. For the classification of sodium content, formulas were applied according to the nutrient profile: high in sodium ≥1 milligram of sodium per calorie. For classification according to regional goals: when the sodium content in 100 grams of product is> the established goal. Results. According to the nutrient profile, 52% of the products are high in sodium. According to regional goals, 24% is formulated above the goals, this reflects differences between the valuations of sodium content by category. Conclution. More than half of the prepackaged food products marketed in El Salvador are classified as high in sodium, according to the nutrient profile. A quarter of these are formulated with sodium above the regional goals, showing that the goals are more flexible in the assessment of maximum sodium content for industrial formulation in relation to the assessment of high sodium content for human consumption

ABSTRACT

Resumo O suporte nutricional nos cuidados paliativos visa melhorar a qualidade de vida do paciente por meio do controle de sintomas associados à alimentação, priorizando os desejos do indivíduo. Há controvérsias quanto à real contribuição da alimentação para o conforto de pacientes em cuidados paliativos na terminalidade de vida, e ainda é preciso esclarecer as competências específicas do nutricionista nessa área. Tendo em vista essas lacunas, a presente revisão integrativa objetiva conhecer como nutricionistas atuam com pacientes em cuidados paliativos no fim de vida. A amostra final foi composta por sete artigos que apontam diferenças entre o cuidado nutricional convencional e em cuidados paliativos e apresentam dilemas bioéticos relacionados à alimentação. Conclui-se que é preciso conhecer melhor o modo de atuar dos nutricionistas na assistência paliativa. Mais estudos sobre o tema devem ser desenvolvidos, considerando não só aspectos nutricionais, mas também o caráter simbólico da alimentação.


Abstract Nutritional support in palliative care aims to improve the quality of life of the patient through the control of symptoms associated with food, prioritizing the desires of the individual. There are controversies regarding the real contribution of food to the comfort of patients in palliative care at the end of life, and it is still necessary to clarify the specific skills of the nutritionist in this area. In view of these gaps, this review integrative objective to know how nutritionists act with patients in palliative care end of life. The final sample was composed of seven articles that point out differences between conventional nutritional care and in palliative care and present bioethical dilemmas related to food. It is concluded that it is necessary to know better how nutritionists act in the palliative care. Further studies on the topic should be developed, considering not only nutritional aspects, but also the character symbolic of food.


Resumen El apoyo nutricional en los cuidados paliativos tiene como objetivo mejorar la calidad de vida del paciente a través del control de los síntomas asociados a la alimentación, priorizando los deseos del individuo. Hay controversias en cuanto a la contribución real de los alimentos para el confort de los pacientes en cuidados paliativos al final de la vida, y todavía es necesario aclarar las habilidades específicas del nutricionista en esta área. En vista de estas lagunas, la presente revisión integradora tiene como objetivo saber cómo actúan los nutricionistas con los pacientes en cuidados paliativos al final de su vida. La muestra final estuvo compuesta por siete artículos que señalan diferencias entre el cuidado nutricional convencional y los cuidados paliativos y presentar dilemas bioéticos relacionados con la alimentación. Se concluye que es necesario conocer mejor cómo actúan los nutricionistas en los cuidados paliativos. Se deben desarrollar estudios adicionales sobre el tema, considerando no solo los aspectos nutricionales, sino también el carácter simbólico de la alimentación.

ABSTRACT

La pérdida de patrones de alimentación tradicionales a favor de otros más occidentales redunda en un descenso de calidad de la dieta alrededor del mundo. Muchos aspectos determinan la calidad dietética, aunque en general pueden resumirse en una dieta moderada, variada, equilibrada y adecuada para cada individuo. Estos aspectos son evaluados por el Diet Quality Index-International (DQI-I). Objetivo: Comparar la calidad de la dieta de población mexicana y española mediante un índice de calidad internacional de la dieta, determinando que factores son en mayor medida responsables de la pérdida de calidad. Material y métodos: Estudio observacional transversal sobre una muestra representativa de sujetos adultos residentes en Querétaro (México) y de sujetos de la misma franja de edad procedentes de la Región de Murcia, en la cuenca mediterránea española. Se recogieron datos sociodemográficos, antropométricos, de frecuencia de consumo de alimentos y de ingesta con 3 recuerdos de 24 horas y se valoró el DQI-I en la población. Resultados: Se encontraron diferencias para el gasto energético y el DQI-I en todos sus aspectos con valores de calidad superiores para la población mexicana. La variedad fue la dimensión más castigada para todos los sujetos, presentando los mexicanos mejores cifras de consumo de vegetales pero peores para las fuentes proteicas. Conclusiones: La muestra mexicana mejoró las cifras de calidad de la española, tal vez por una mayor influencia de conocimientos en nutrición. El 86% de la población podría mejorar sus puntajes de calidad en el DQI-I ajustando sus frecuencias de consumo de alimentos(AU)


The loss of traditional eating patterns in favour of more Western ones results in a decline in dietary quality around the world. Many aspects determine dietary quality, but in general they can be summarised as a moderate, varied, balanced diet suitable for each individual. These aspects are assessed by the Diet Quality Index-International (DQI-I). Objective: To compare the quality of the diet of the Mexican and Spanish populations using an international diet quality index, determining which factors are most responsible for the loss of quality. Material and methods: Cross-sectional observational study on a representative sample of adult subjects living in Querétaro (Mexico) and subjects of the same age group from the Region of Murcia, in the Spanish Mediterranean basin. Sociodemographic, anthropometric, food frequency consumption and intake data were collected with 3 24-hour recall and the DQI-I was assessed in the population. Results: Differences were found for energy expenditure and DQI-I in all aspects with higher quality values for the Mexican population. Variety was the most punished dimension for all subjects, with Mexicans presenting better figures for vegetable intake but worse for protein sources. Conclusions: The Mexican sample improved the quality figures of the Spanish sample, perhaps due to a greater influence of nutritional knowledge. Eighty-six percent of the population could improve their DQI-I quality scores by adjusting their food consumption frequencies(AU)

ABSTRACT

The insertion of men in the university environment is a complex and worrying phenomenon permeated by vulnerabilities, which are associated with the adoption of risky behaviors for health. The objective of this study was to evaluate the health behavior of Brazilian university men. A cross-sectional study with 663 men students. The study used a questionnaire on health-related life habits. All the questions were extracted from the Surveillance of Risk and Protection Factors for Chronic Diseases through Telephone Interviews. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals and chi-square tests. The analysis of the joint relationships between nutritional status, physical activity and diet was conducted by the multiple correspondence analysis. Of the 663 students, 67.8% were between 20-29 years of age, 69.2% consumed alcohol, 34.5% did not do physical activity, and 34.2% were overweight. The students who did not engage in physical activity smoked more (p=0.05), consumed less fruit (p<0.01), less salad (p<0.01), and consumed full fat milk (p=0.05). In the physically inactive students, a high prevalence of acquiring diabetes mellitus (p<0.01) and high cholesterol (p<0.01) was observed. University students were found to have unhealthy lifestyles. More public policies aimed at promoting preventive measures at universities are needed to encourage healthier health behaviors(AU)


La inserción de los varones en el ámbito universitario es un fenómeno complejo y preocupante permeado por vulnerabilidades, las cuales están asociadas a la adopción de conductas de riesgo para la salud. El objetivo del trabajo fue evaluar el comportamiento de salud de los varones universitarios brasileños. Estudio transversal con 663 varones. El estudio utilizó un cuestionario sobre hábitos de vida relacionados con la salud. Todas las preguntas fueron extraídas de la Vigilancia de Factores de Riesgo y Protección de Enfermedades Crónicas mediante entrevistas telefónicas (Vigitel). Se utilizó la regresión logística para estimar los odds ratios (OR) y los intervalos de confianza del 95% and pruebas del test chi-cuadrado. El análisis de las relaciones conjuntas entre estado nutricional, actividad física y dieta se realizó mediante el análisis de correspondencias múltiples. De los 663 varones, el 67,8% tenía entre 20 y 29 años, el 69,2% consumía alcohol, el 34,5% no hacía actividad física y el 34,2% tenía sobrepeso. Los varones que no realizaron actividad física fumaron más (p = 0,05), consumieron menos fruta (p<0,01), menos ensalada (p<0,01) y consumieron leche entera (p = 0,05). En los varones físicamente inactivos, se observó una alta prevalencia de diabetes mellitus (p<0,01) y colesterol alto (p<0,01). Se descubrió que los varones universitarios tenían estilos de vida poco saludables. Se necesitan más políticas públicas orientadas a promover medidas preventivas en las universidades para fomentar comportamientos de salud más saludables(AU)

ABSTRACT

Kuhn in 1962 establishes the revolutionary character of science: "new scientific theories are not born by verification or falsification, but by substitution." The objective of this review was to analyze the ideas and paradigms through which studies on obesity and its relationship with environmental pollutants, diet and epigenetics have passed, in order to illustrate the current situation of this object of study. Articles were managed in December 2020 from the Web of Science. The strategy was Obesity AND (pollution OR contamination) in the Title field, AND (epigenetic* OR obesity OR food OR nutrition OR diet) in the Themes field. 654 articles were obtained: 577 original investigations and 77 reviews. The documents were exported in BibTeXformat to be quantitatively analyzed with the Bibliometrix program. For the qualitative analysis, review articles were selected in whose titles, keywords and/or abstract, carried the word paradigm*, identifying 19 who underwent content analysis. From 1980 to 2020, four periods were recognized, the first and third are classified as normal science; the second and the fourth, crisis of knowledge or revolution. The evolution of the studies has been differentiated. First, the central theme was environmental pollution and secondarily, obesity. For the second and third period, the epigenetics related to environmental pollution and that associated with obesity are investigated separately and at present, causal relationships between environmental pollutants and obesity, nutrients and epigenetics are hypothesized.


Kuhn en 1962 establece el carácter revolucionario de la ciencia: "las nuevas teorías científicas no nacen por verificación ni por falsación, sino por sustitución". El objetivo de esta revisión fue analizar las ideas y los paradigmas por los que han transitado los estudios sobre obesidad, y su relación con contaminantes ambientales, alimentación y epigenética, con el propósito de ilustrar la situación actual de este objeto de estudio. Se gestionaron artículos en diciembre de 2020 de la Web of Science. La estrategia fue Obesity AND (pollution OR contamination) en el campo Title, AND (epigenetic* OR obesity OR alimentation OR nutrition OR diet) en el campo Themes. Se obtuvieron 654 artículos: 577 investigaciones originales y 77 revisiones. Los documentos se exportaron en formato BibTeX para ser analizados cuantitativamente con el programa Bibliometrix. Para el análisis cualitativo se seleccionaron artículos de revisión en cuyos títulos, palabras clave o resumen llevaran la palabra paradigm*, con lo que se identificaron 19, a los que se les realizó análisis de contenido. De 1980 a 2020 se reconocieron cuatro períodos; el primero y el tercero se clasifican como ciencia normal; el segundo y el cuarto, como crisis de conocimiento o revolución. La evolución de los estudios ha sido diferenciada. Primero, la temática central fue la contaminación ambiental y, de manera secundaria, la obesidad. Para el segundo y el tercer período se investigan por separado la epigenética relacionada con la contaminación ambiental y la asociada con la obesidad, y en la actualidad, se plantean hipótesis de relaciones causales entre contaminantes ambientales y obesidad, nutrientes y epigenética.

ABSTRACT

La vitamina D es esencial para el funcionamiento del organismo. Su deficiencia puede estar asociada tanto a patologías óseas, como a otras afecciones sistémicas. La prevalencia de la hipovitaminosis está aumentando, en todas las edades, incluidos niños y adolescentes. El objetivo del presente estudio fue evaluar los niveles sanguíneos de vitamina D en niñas colombianas, analizando también la dieta, la actividad física y la exposición solar. Se realizó un estudio descriptivo transversal con 52 niñas sanas prepúberes de Pasto (Colombia), entre 7 y 10 años. Se analizaron los niveles de albúmina, calcio, fósforo, magnesio, calcitriol (1,25 dihidroxicolecalciferol) y calcidiol (25 hidroxicolecalciferol). Se realizaron encuestas sobre hábitos alimentarios, actividad física y exposición solar. El 51,1% de las niñas evaluadas presentó insuficiencia de 25-OH-VITD y el 40% presentó deficiencia (< 20 ng/mL). Ninguna niña se encontraba en desnutrición u obesidad, el 10% se encontraba en riesgo de bajo peso (IMC ≤ -1DE y > -2DE), el 4 % presentaba sobrepeso (≥ +1DE y < +2DE), y el 34 % se encontraban en riesgo de talla baja (T/E: -1 y -2 DE). La ingesta media de calorías/día fue inferior a las recomendadas. Se observó una ingesta deficiente de vitamina D, calcio y magnesio (p > 0,05), así como de fibra (p > 0,05). Se pone de manifiesto una deficiencia de vitamina D en las niñas evaluadas a pesar de tener una actividad física y una exposición solar adecuadas. Además, se observan ingestas deficientes de fibra, calcio, magnesio y vitamina D. Habría por tanto que asegurar la ingesta e incluso suplementar para evitar problemas de salud en la edad adulta(AU)


Vitamin D is essential for the body to function. Its deficiency can be associated with bone pathologies as well as other systemic conditions. The prevalence of hypovitaminosisis increasing, in all ages, including children and adolescents. The objective of this study was to evaluate blood levels of vitamin D in Colombian girls, also analyzing diet, physical activity and sun exposure. A descriptive cross-sectional study was carried out with 52 healthy prepubertal girls from Pasto (Colombia), between 7 and 10 yearsold. The levels of albumin, calcium, phosphorus, magnesium, calcitriol (1.25 dihydroxycholecalciferol) and calcidiol (25 hydroxycholecalciferol) were analyzed. Surveys were conducted one a ting habits, physicalactivity and sun exposure. 51.1% of the girls evaluated presented 25-OH-VITD insufficiency and 40% presented deficiency (<20 ng / mL). None of the girls were under nourished or obese, 10% were at risk of low weight (BMI ≤ -1SD and> -2SD), 4% were overweight (≥ + 1DE and <+ 2DE), and 34% were they were at risk of short stature (T / E: -1 and -2 SD). The average calorie intake / day was lower than recommended. A deficient intake of vitamin D, calcium and magnesium (p> 0.05), as well as fiber (p> 0.05) was observed. A vitamin D deficiency is evident in the girls evaluated despite adequate physical activity and sun exposure. In addition, deficient intakes of fiber, calcium, magnesium and vitamin D are observed. Therefore, it would be necessary to ensure the intake and even supplement to avoid health problems in adulthood(AU)

ABSTRACT

O câncer de bexiga se inicia nas células que revestem a bexiga as quais sofrem um crescimento anormal devido às mutações. O carcinoma urotelial é o nono tipo de câncer mais frequente no mundo, e em geral é diagnosticado como uma doença superficial. O objetivo dessa pesquisa é saber quais são os riscos prevalentes para o câncer de bexiga. O levantamento bibliográfico desta revisão foi realizado por meio de busca por artigos científicos encontrados em bancos de dados da Scielo, Pubmed, Biblioteca Virtual em saúde (BVS) e no Google acadêmico. Foram utilizados ao todo 23 artigos, sendo artigos científicos, resumos e revisões no período de dezembro de 2019. Nas últimas décadas, a incidência global desse câncer parece estar crescendo e isso poderá ser consequência dos efeitos dos riscos. Cerca de 20% dos casos de câncer de bexiga estão associados a riscos de exposição ocupacional, tabagismo, carcinógenos industriais, as aminas aromáticas, substâncias químicas orgânicas, e uma série de atividades profissionais. Também, consideram-se risco os medicamentos, a dieta e as infecções por parasitas. Nesta pesquisa foram apresentados os principais riscos estabelecidos e propostos ao desenvolvimento do câncer de bexiga.


Bladder cancer begins in the cells lining the bladder that undergo abnormal growth due to mutations. Urothelial carcinoma and the ninth most common cancer in the world, is generally diagnosed as a superficial disease. The purpose of this research is to find out what are the prevalent risks for bladder cancer. The bibliographic survey of this review was carried out by searching for scientific articles found in Scielo, PubMed, Virtual Health Library (VHL) databases and in Google academic. A total of 23 articles were used, including scientific articles, abstracts, reviews in the period of December 2019. In the last decades, the global incidence of this cancer seems to be increasing and this may be a consequence of the effects of the risks. About 20% of bladder cancer cases are associated with occupational exposure risks, smoking, industrial carcinogens, aromatic amines, organic chemicals in a range of professional activities. Also, drugs, diet and parasite infections are considered risky. This research presented the main risks established and proposed for the development of bladder cancer.

ABSTRACT

Abstract This paper argues that many of the foundations and trends that led to the rise in obesity and other diet-related health problems in Latin America began to develop in the late nineteenth century. The tendency towards presentism in the nutrition transition literature provides a much abbreviated and limited history of changes in diet and weight. Whereas medical and nutrition researchers have tended to emphasize the recent onset of the crisis, a historical perspective suggests that increasingly global food sourcing prompted changes in foodways and a gradual "fattening" of Latin America. This paper also provides a methodological and historiographic exploration of how to historicize the nutrition transition, drawing on a diverse array of sources from pre-1980 to the present.


Resumo Este trabalho argumenta que fundamentos e tendências que levaram ao aumento da obesidade e de outros problemas de saúde relacionados à alimentação na América Latina começaram a surgir no final do século XIX. A propensão ao presentismo na literatura sobre transição nutricional produz uma história abreviada e limitada das mudanças em alimentação e peso. Embora pesquisadores médicos e nutricionistas enfatizem a recente instalação da crise, uma perspectiva histórica sugere que fontes alimentares crescentemente globalizadas resultaram em mudanças na alimentação e em gradual "aumento de gordura" na população latino-americana. O artigo propõe ainda a exploração metodológica e historiográfica de como historicizar a transição nutricional recorrendo a fontes pré-1980 até o momento.

ABSTRACT

A raiz do yacon (Smallanthus sonchifolius), em função da rica concentração de fruto-oligossacarídeos, é classificada como prebiótico e tornou-se promissora da obesidade pelo aumento da saciedade. O objetivo deste estudo foi avaliar a inclusão de um produto à base de yacon (PBY) em ratas ovariectomizadas (OVX) no consumo alimentar, na modulação de medidas antropométricas e do imunomarcador da saciedade glucagon-like peptide-1 (GLP-1) em ratas Wistar ovariectomizadas (OVX). Analisou-se o consumo alimentar pela pesagem diária de sobra de dieta, a porcentagem de gordura corporal foi determinada pelo índice de Lee e também foram avaliados o peso, o índice de massa corporal (IMC) e circunferência abdominal. Fragmentos do ceco foram utilizados para imunomarcação de GLP-1, de ratas OVX, após serem alimentadas por 24 semanas com dieta padrão adicionadas ou não de 6% de FOS/inulina/PBY. Observou-se diminuição da circunferência abdominal (p=0,2173) em 3,5%, também houve decréscimo de IMC (p=0,3822) em 6,25% e de percentual de gordura corporal (p=0,3528) em 2,14% em animais que receberam PBY durante 24 semanas (G4) comparado aos animais do grupo controle. No grupo G4 o GLP-1 aumentou (p<.0001), os animais aumentaram o consumo (p=0,0064) e, paradoxalmente, tiveram menor ganho de peso (p<.0001), o que pode estar associado ao fato de que as fibras diminuem a eficiência de absorção de lipídeos ao longo do intestino delgado, o que pode diminuir a assimilação calórica de nutrientes. Esse fenômeno demonstra que o PBY possui potencial na modulação da obesidade, portanto, melhoria da qualidade de vida de mulheres na menopausa.(AU)


The yacon root (Smallanthus sonchifolius), due to the rich concentration of fructo-oligosaccharides, is classified as prebiotic and has become promising for obesity due to increased satiety. The aim of this study was to evaluate the inclusion of a yacon-based product (PBY) in ovariectomized rats (OVX) in food consumption, in the modulation of anthropometric measurements and in the satiety immunosorbent glucagon-like peptide-1 (GLP-1) in rats Wistar ovariectomized (OVX). Food consumption was analyzed by daily weighing of leftover diet, the percentage of body fat was determined by the Lee index, and weight, body mass index (BMI) and waist circumference were also evaluated. Cecum fragments were used for immunostaining GLP-1, from OVX rats, after being fed for 24 weeks with a standard diet with or without 6% FOS / inulin / PBY. There was a decrease in abdominal circumference (p = 0.2173) in 3.5%, there was also a decrease in BMI (p = 0.3822) in 6.25% and a percentage of body fat (p = 0.3528) 2.14% in animals that received PBY for 24 weeks (G4) compared to animals in the control group. In the G4 group GLP-1 increased (p <.0001), the animals increased their consumption (p = 0.0064) and paradoxically, they gained less weight gain (p <.0001), which may be associated with the fact that fibers decrease the efficiency of absorption of lipids along the small intestine, which can decrease the caloric assimilation of nutrients. This phenomenon demonstrates that PBY has the potential to modulate obesity, thus improving the quality of life of women in menopause. (AU)

ABSTRACT

BACKGROUND@#The 2019 novel coronavirus disease (COVID-19) has had a massive impact on public health, resulting in sudden dietary and behavioral habit changes. Frontline epidemic prevention workers play a pivotal role against COVID-19. They must face high-risk infection conditions, insufficient anti-epidemic material supplies, mental pressure, and so on. COVID-19 seriously affects their dietary and behavioral habits, and poor habits make them more susceptible to COVID-19. However, their baseline dietary and behavioral habits before COVID-19 and their willingness to change these habits after the outbreak of COVID-19 remain unclear for these workers in China. This study aimed to explore the baseline dietary and behavioral habits of frontline workers and their willingness to change these habits after the outbreak of the epidemic; in addition, susceptible subgroups were identified by stratified analyses as targets of protective measures to keep them from being infected with COVID-19.@*METHODS@#A cross-sectional study was conducted through an online questionnaire using a sample of 22,459 valid individuals living in China, including 9402 frontline epidemic prevention workers.@*RESULTS@#Before COVID-19, 23.9% of the frontline epidemic prevention workers reported a high-salt diet, 46.9% of them reported a high frequency of fried foods intake, and 50.9% of them smoked cigarettes. After the outbreak of COVID-19, 34.6% of them expressed a willingness to reduce salt intake, and 43.7% of them wanted to reduce the frequency of pickled vegetables intake. A total of 37.9% of them expressed a willingness to decrease or quit smoking, and 44.5% of them wanted to increase sleep duration. Significant differences in the baseline dietary and behavioral habits and the willingness to change their habits were observed between frontline epidemic prevention workers and other participants. Among the frontline epidemic prevention workers with poor dietary and behavioral habits before COVID-19, frontline epidemic prevention experience was a promoting factor for adopting worse dietary and behavioral habits, including those in the high-salt intake subgroup (OR, 2.824; 95% CI, 2.341-3.405) and the 11-20 cigarettes/day subgroup (OR, 2.067; 95% CI, 1.359-3.143).@*CONCLUSIONS@#The dietary and behavioral habits of frontline epidemic prevention workers were worse than that those of other participants before COVID-19. They had a greater willingness to adopt healthy dietary and behavioral habits after experiencing the outbreak of COVID-19. However, frontline epidemic prevention workers with poor dietary and behavioral habits before COVID-19 continued in engage in these poor habits. Dietary and behavioral intervention policies should be drafted to protect their health, especially frontline epidemic prevention workers with poor habits at baseline.
