ABSTRACT
BACKGROUND/AIMS: Bone mineral density (BMD) is often low in patients with Crohn's disease (CD). This study aimed to evaluate the association between nutritional factors and BMD in a group of CD patients. METHODS: CD patients 18 years of age or older were included. The body mass index (BMI), waist circumference (WC) and dietary intake were evaluated during two 24-hour recalls. Bone densitometry was performed by dual-energy X-ray absorptiometry of the full body to assess body composition and of the lumbar vertebrae and femoral neck to assess BMD. RESULTS: In the 60 patients evaluated, there was no association between BMD and disease activity or between BMD and disease duration. We observed moderate correlations between BMD in at least one of the evaluated sites and BMI, lean mass, WC, and protein, calcium, phosphorus and magnesium dietary intakes (P < 0.05). In the linear regression analysis for spinal BMD, only BMI and calcium dietary intake remained associated (P < 0.05). In the linear regression analysis for femoral BMD, WC and phosphorus intake continued to be significant in the final model, although they had low explanatory power for BMD (P < 0.05). CONCLUSIONS: The prevalence of low BMD was high in CD patients. BMI, WC, calcium and phosphorus dietary intake were positively correlated with BMD.

O presente estudo teve como objetivo caracterizar genótipos de soja-hortaliça, por meio de características agronômicas, nutricionais e antinutricionais, utilizando-se a Análise de Componentes Principais. O experimento foi conduzido em condições de campo no Setor de Olericultura e Plantas Aromático-Medicinais na UNESP-FCAV. O delineamento experimental foi em blocos casualizados com cinco genótipos e quatro repetições. Avaliaram-se as variáveis: número de vagens por planta, número de sementes por vagem, massa fresca das vagens por planta (g), massa fresca de 100 sementes (g), produtividade total estimada de grãos imaturos (kg ha-1), teor de umidade, proteínas, lipídeos, cinzas, carboidratos, isoflavonas e inibidores de tripsina Kunitz. As variáveis que contribuíram na discriminação dos genótipos no primeiro componente principal foram: peso total de vagens por planta, teor de proteínas, número de vagens por planta, peso de 100 sementes e teor de umidade, enquanto que aquelas que contribuíram no segundo componente principal foram: teor de cinzas, proteínas, número de vagens por planta e teor de lipídeos. Os genótipos JLM010, JLM024 e CNPSO1, destacaram-se por serem influenciados pelo peso total de vagens por planta, produtividade estimada, número de vagens por planta, teor de carboidratos, isoflavonas e de proteínas, sendo considerados genótipos de soja-hortaliça com potencial para serem utilizados em programas de melhoramento genético vegetal.
This study presents the characterization of vegetable soybean genotypes. It was applied Principal Component Analysis considering the agronomics, nutritional and antinutritional features: number of pods per plant, number of seeds per pod, fresh weight of pods per plant (g), fresh weight of 100 seeds (g), estimated total yield of immature seeds (kg ha-1), moisture content, proteins, lipids, ash, carbohydrates, isoflavones and Kunitz trypsin inhibitor. The experiments were developed in the sector of Olericultura and Plantas Aromático-Medicinais from UNESP-FCAV. The results showed that fresh weight of pods per plant, proteins content, number of pods per plant, fresh weight of 100 seeds, and moisture content were the relevant variables for the discrimination of the genotypes in the first principal component and for the second principal the component were ash content, proteins, number of pods per plant and lipids content. Accordingly, the genotypes JLM010, JLM024 and CNPSO1 were defined as relevant by the variables fresh weight of pods per plant, estimated total yield of immature seeds, number of pods per plant, carbohydrates content, isoflavones and proteins. It was concluded that it is a relevant result because these genotypes were considered candidates to be used in plant breeding programs.
ABSTRACT
Las enfermedades cardiovasculares constituyen un problema de salud pública en muchos países y en Cuba. Las recomendaciones de estilos de vida saludables pueden a largo plazo disminuir o eliminar en la población las enfermedades cardiovasculares. Objetivos: Identificar los aspectos nutricionales, donde se incluyen los factores de riesgo para estas entidades: hiperlipoproteinemias, hipertensión arterial y la obesidad, en especial la abdominal. Se incluye la clasificación del estado nutricional por el índice de masa corporal (IMC) y la distribución de la grasa por la circunferencia de la cintura. Se enfatiza en la dietoterapia y en el cálculo de los requerimientos de energía y nutrimentos de forma individual. También esta revisión aborda con profundidad a los macronutrientes y micronutrientes, así como a la fibra dietética. La dieta saludable y necesaria para los pacientes con enfermedad cardiovascular debe ser baja en grasas saturadas, colesterol y ácidos grasos trans. La meta es cambiar de forma permanente los hábitos alimentarios y el aumento de la actividad física acorde al estado cardiovascular del paciente. Para alcanzar estos propósitos la dieta debe ser rica en frutas y vegetales, pescado graso, pollo, carne magra, legumbres, cereales y granos integrales. Se hace énfasis en la prevención de estas enfermedades
The cardiovascular diseases are a public health problem in many countries and in Cuba. The recommendations of healthy lifestyles may at long term to decrease or to eliminate the cardiovascular diseases present in population. Objectives: To identify the nutritional features including the risk factors for these entities: hyperlipoproteinemias, high blood pressure and obesity specially the abdominal one. The classification of nutritional status by body mass index (BMI) and the fat distribution by waist circumference are included. It is emphasized the dietary therapy and the estimates of energy requirements and individual feedings. Present review also approaches deeply the macronutrients and the micronutrients, as well as the dietary fiber. A healthy and necessary for patients presenting with a cardiovascular disease must to be low in saturated fats, cholesterol and the trans-fatty acids. The goal of present paper is to change the permanent way of alimentary habits and the increase of physical activity according to the patient's cardiovascular status. To achieve these goals the diet must to be rich in fruits and vegetables, fat fish, chicken, lean meat, pod vegetables, cereals and integral grains. It is emphasized the prevention of these diseases
