Relação entre hábitos alimentares, peso corporal e saúde intestinal em indivíduos adultos.

Introduction: Dysbiosis may be related to poor eating habits and metabolic changes that can contribute to being overweight. Objective: To evaluate the food choices that modulate the gut microbiota and the association between gut health and body weight in adult individuals. Method: Analytical, correlational-descriptive, cross-sectional study conducted with 99 adult participants of both sexes. A Sociodemographic and Food Frequency Questionnaire was used to collect sociodemographic data, body weight, height, and frequency of consumption of food sources of prebiotics and probiotics; and the Metabolic Tracking Questionnaire was applied to investigate gut health. The study took place online, via Google Forms, and was disseminated through social media (Facebook, Instagram, WhatsApp). A descriptive analysis of the data was performed and for association between variables, the Pearson's Chi-square test was used.   Results: Of the total number of participants, 74.7% were women. As for the classification of Body Mass Index, 60.6% were eutrophic, 24.2% were overweight, and 9.1% were somewhat obese. The most consumed probiotic and prebiotic food sources were cheese, yogurt, fermented kinds of milk; and banana, apple, and oatmeal, respectively. However, these are foods that are not part of the daily consumption for most participants. There was no significant difference between the association of the Body Mass Index with the sex of the participants or the final Metabolic Tracking Questionnaire score and the final sum of gastrointestinal symptoms (p=0.76, p=0.29, p=0.70). Conclusion: A low frequency of consumption of foods that aid intestinal health is noted. However, body weight was not found to influence the composition of the gut microbiota.Introducción: La disbiosis puede estar relacionada con malos hábitos alimentarios y alteraciones metabólicas que pueden contribuir al sobrepeso. Objetivo: Evaluar las elecciones alimentarias que modulan la microbiota intestinal y la asociación entre la salud intestinal y el peso corporal en personas adultas. Método: Estudio analítico, correlacional-descriptivo y transversal realizado con 99 personas participantes adultas de ambos sexos. Se utilizó un cuestionario sociodemográfico y de frecuencia alimentaria para recoger datos sociodemográficos, peso corporal, altura, frecuencia de consumo de fuentes alimentarias de prebióticos y probióticos y el Cuestionario de Seguimiento Metabólico para investigar la salud intestinal. El estudio se realizó online, a través de formularios de Google, siendo difundido a través de redes sociales (Facebook, Instagram, WhatsApp). Se realizó un análisis descriptivo de los datos y para la asociación entre variables se empleó el test Chi-cuadrado de Pearson. Resultados: Del total de participantes, el 74.7 % fueron mujeres. En cuanto a la clasificación del Índice de Masa Corporal, el 60.6 % eran personas eutróficas, el 24.2 % con sobrepeso y el 9.1% personas obesas. Los alimentos fuente de probióticos y prebióticos más consumidos fueron el queso, el yogur, las leches fermentadas, el plátano, la manzana y la avena. Sin embargo, se trata de alimentos que no forman parte del consumo diario de la mayoría de los participantes. No hubo diferencias significativas entre la asociación del Índice de Masa Corporal con el sexo, la puntuación final del Cuestionario de Seguimiento Metabólico y la suma final de síntomas gastrointestinales (p=0.76, p=0.29, p=0.70), respectivamente. Conclusiones: Se observa una baja frecuencia de consumo de alimentos que ayudan a la salud intestinal. Sin embargo, no se encontró que el peso corporal ejerza influencia sobre la composición de la microbiota intestinal.Introdução: A disbiose pode estar relacionada à hábitos alimentares ruins e alterações metabólicas que podem contribuir para o excesso de peso. Objetivo: Avaliar as escolhas alimentares que modulam a microbiota intestinal e a associação entre a saúde intestinal e o peso corporal de indivíduos adultos. Método: Estudo analítico, correlacional-descritivo e transversal realizado com 99 participantes, adultos, de ambos os sexos. Utilizou-se um Questionário Sociodemográfico e de Frequência Alimentar para coletar dados sociodemográficos, peso corporal, altura, frequência de consumo de alimentos fontes de prebióticos e probióticos e o Questionário de Rastreamento Metabólico (QRM), para investigar a saúde intestinal.

Conclusão: Nota-se uma baixa frequência de consumo de alimentos que auxiliam na saúde intestinal. No entanto, não foi constatado que o peso corporal exerce influência na composição da microbiota intestinal

Profundidad de siembra y tamaño de las semillas: desarrollo de las plántulas de frijol Mungo

Contextualization: The mung bean is widely cultivated in Asia and Brazil, it has emerged as an option for cultivation in the second crop in the Central West Brazil, especially rotation with grasses is intended; however, the uneven and slow emergence of mung bean seedlings can lead to delays in the development of the crop and impair the final stand.    Knowledge gap: Some of the conditions that affect the initial establishment of the crop are the sowing depth and the size of the seed. These factors are still under discussion in the scientific environment, especially for a culture recently introduced in Brazil.    Purpose: the objective was to evaluate the effect of seed size and sowing depth standardization on the performance of mung bean seedlings.    Methodology: The trial was conducted in a Red Latosol, with Aw climate, average annual rainfall of 1300 mm and bimodal distribution. The experimental design used was completely randomized, in a 2 × 3 factorial scheme with 8 replicates of 25 seeds, totaling 48 plots. The factors analyzed were two seed size (3 and 4 mm) and three sowing depths (1, 2 and 3 cm). The emergency speed index (ISE), non-emerged seedlings, normal seedlings, fresh mass, dry mass and seedling length were evaluated. The data were submitted to variance analysis and, when significant at 5% probability, a Tukey test was applied to compare the means of the factors under study.  Results and conclusions: It was verified that, when sown at 1 cm depth, the seeds of mung bean have lower ISE, however, they obtained a lower percentage of seedlings not relevant for the study, and a higher percentage of normal seedlings emerged than at a depth of 3 cm. Thus, the most recommended depth for the sowing of mung beans was 2 cm, regardless of the size of the seed used. The seed class of 4 mm allowed the development of seedlings with higher dry matter accumulation.Contextualización del tema: el frijol mungo es ampliamente cultivado en Asia y en Brasil, y ha surgido como una opción para el cultivo en el segundo cultivo en el Centro Oeste de Brasil, especialmente cuando se pretende la rotación con pastos; sin embargo, la aparición desigual y lenta de las plántulas de frijol mungo puede conducir a retrasos en el desarrollo del cultivo y perjudicar la posición final.    Vacío de investigación: algunas de las condiciones que afectan al establecimiento inicial del cultivo son la profundidad de siembra y el tamaño de la semilla. Estos factores todavía están siendo discutidos en el entorno científico, especialmente para una cultura recientemente insertada en Brasil.    Propósito del estudio: el objetivo fue evaluar el efecto del tamaño de las semillas y la estandarización de la profundidad de la siembra en el rendimiento de las plántulas de frijol mungo.    Metodología: el ensayo se llevó a cabo en un Latossuelo Rojo, con clima Aw, precipitación media anual de 1300 mm y distribución bimodal. El diseño experimental utilizado fue completamente aleatorio, en un esquema factorial de 2 × 3 con 8 réplicas de 25 semillas, con un total de 48 parcelas. Los factores analizados fueron de los tamaños de semilla (3 y 4 mm) y tres profundidades de siembra (1, 2 y 3 cm). Se evaluó el índice de velocidad de emergencia (IVE), las plántulas no emergidas, las plántulas normales, la masa fresca, la masa seca y la longitud de las plántulas. Los datos se sometieron al análisis de varianza y, cuando se aplicaba una probabilidad significativa del 5%, se aplicó una prueba de Tukey para comparar los medios de los factores en estudio.    Resultados y conclusiones: se verificó que, cuando se siembran a 1 cm de profundidad, las semillas de frijol mungo tienen IVE más bajo; sin embargo, obtuvieron un menor porcentaje de plántulas no relevantes para el estudio, y un mayor porcentaje de plántulas normales emergió a una profundidad de 3 cm. Por lo tanto, la profundidad más recomendada para la siembra de frijoles mungo fue de 2 cm, independientemente del tamaño de la semilla utilizada. Lo tamaño de semilla de 4 mm permitió el desarrollo de plántulas con mayor acumulación de materia seca

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Nitrogen and Potassium Fertilization in the Initial Growth of Annona crassiflora Mart.

ABSTRACT Annona crassiflora Mart. presents medicinal and food potential, and is also used in the recovery of degraded areas, however, little is known about its nutritional requirements. The aim of this work was to analyze the initial growth of A. crassiflora submitted to nitrogen and potassium fertilization. The experiment was conducted with a complete randomized block design with four replicates, each consisting of five nitrogen and potassium doses (0, 50, 100, 150 and 200 mg dm-3). Results were submitted to regression analysis. The species showed significant response for nitrogen fertilization regarding biometric variables, biomass, DQI and nutritional contents at doses of 100 to 200 mg dm-3. On the other hand, potassium only influenced DQI, nutritional content and accumulation of A. crassiflora seedlings
