RESUMEN El arándano es un fruto que posee una fuente importante de componentes bioactivos beneficiosos para la dieta humana, como las antocianinas y fenoles totales, que se ven alterados por el uso de temperaturas altas durante el procesamiento. El objetivo de este estudio fue evaluar el uso de redes neuronales artificiales en la optimización de la concentración de sacarosa y el tiempo para el pretratamiento osmótico de arándanos de la variedad Biloxi, con la finalidad de retener la mayor cantidad de antocianinas y componentes fenólicos totales en la elaboración posterior de mermelada. Se utilizó redes neuronales artificiales del tipo feedfoward, con algoritmo de entrenamiento de Backpropagation con ajuste de pesos de Levenberg-Marquardt para lograr la combinación óptima predicha que maximice la retención de estos componentes bioactivos. El modelo logró su mejor rendimiento con 11 neuronas en la capa oculta, logrando un coeficiente R2 de 0,98 y un error cuadrático medio de 4,76; lo que indica una gran capacidad de generalización. Las redes neuronales artificiales permitieron obtener la mejor combinación de los factores experimentales -concentración de sacarosa (1,64 M) y tiempo (211,52 min)- que maximizaron los contenidos de antocianinas monoméricas totales (70,98 mg cianidina-3-O-glucósido 100 g-1) y fenoles totales (110,54 mg AGE g-1) presentes en mermelada. En cambio, mediante optimización de respuesta se obtuvo que la combinación de factores experimentales que maximizó las antocianinas totales (71,59 mg cianidina-3-O-glucósido 100 g-1 de mermelada) fue 1,54 M de sacarosa y 232,73 min y para fenoles totales (111,06 mg GAE g-1 de mermelada) 1,79 M y 196,36 min. El uso de redes neuronales artificiales es una excelente alternativa para modelar fenómenos, en comparación con los métodos tradicionales.

ABSTRACT Blueberries are a fruit that is an important source of bioactive components beneficial to the human diet, such as anthocyanins and total phenolics, which are altered by the use of high temperatures during processing. This study aimed to evaluate the use of artificial neural networks in the optimization of sucrose concentration and time for the osmotic pre-treatment of blueberries of the Biloxi variety, to retain the greatest amount of anthocyanins and total phenolics in the subsequent preparation of jam. Artificial neural networks of the feedforward type were used, with a Backpropagation training algorithm with Levenberg-Marquardt weight adjustment, to achieve the optimal predicted combination that maximizes the retention of these bioactive components. The model achieved its best performance with 11 neurons in the hidden layer, achieving an R2 coefficient of 0.98 and a mean square error of 4.76, indicating a strong ability for generalization. Artificial neural networks allowed to obtain the best optimal combination of predicted multiple responses of factors consisting of a sucrose concentration of 1.64 M and a time of 211.52 min, which retained a higher content of total monomeric anthocyanins with 70.98 mg cyanidin-3-O-glucoside 100 g-1 of jam and total phenolics with 110.54 mg GAE g-1 of jam. On the other hand, through single-response optimization was obtained that the combination of experimental factors that maximized total anthocyanins (71.59 mg cyanidin-3-O-glucoside 100 g-1 of jam) was 1.54 M of sucrose and 232.73 min and for total phenols (111.06 mg GAE g-1 of jam) 1.79 M of sucrose and 196.36 min. The use of artificial neural networks is an excellent alternative for modeling phenomena, compared to traditional methods.

Resumo Aglutinantes são produtos usados para unir, colar ou manter juntos os vários ingredientes da ração, a fim de conservar a integridade do pellet. Para os aquicultores, a fabricação de ração é uma atividade difícil e cara por causa do alto preço dos aglutinantes artificiais tradicionais. O uso de amidos de grãos como aglutinantes de rações aquáticas tem vantagens que incluem acessibilidade, disponibilidade, contribuição nutricional e minimização do custo da ração. Um ensaio de pesquisa foi conduzido para testar propriedades físicas, como palatabilidade, estabilidade em água, pulverulência, friabilidade, velocidade de sedimentação e tempo de flutuação de amido disponível localmente, ou seja, glúten de trigo, amido de ervilha e goma de guar, e para auxiliar sua incorporação em rações aquáticas. Os resultados revelaram que, entre esses três amidos, o amido de ervilha se mostrou superior aos outros dois (glúten de trigo e goma de guar), pois todos os parâmetros de qualidade física (pulverulência, estabilidade da água e friabilidade) obtiveram melhor desempenho, exceto peletabilidade, em que a goma de guar se destacou. Nenhuma dieta se mostrou melhor no caso de tempo de flotação (Tf) e velocidade de sedimentação em comprimentos variados (6 mm, 9 mm e 12 mm). Essa descoberta indica a importância de aglutinantes adequados para a poluição ótima da água e a aquicultura sustentável. O uso desses aglutinantes, ou seja, glúten de trigo, amido de ervilha e goma de guar, em pellets de ração para peixes também pode reduzir a dependência de aglutinantes sintéticos e minimizar o custo.

Abstract Binders are the products that are used to bind, glue or hold the various feed ingredients together in order to maintain pellet integrity. For aqua-culturists, feed manufacturing is an expensive exercise due to the high cost of ingredients along with traditional artificial binders. The use of grain starches as aqua feed binders have advantages which include availability of that binder, nutritional contribution, and minimization of feed cost. A research trial was conducted to test physical properties such as palatability, water stability, dustiness, friability, settling velocity and floatation time of locally available starch i.e. wheat gluten, pea starch and guar gum and to assist their incorporation in on-farm aqua feed. Results revealed that among these three starch, the starch from pea source was proved superior over other two (wheat gluten and guar gum) as all physical quality parameters (dustiness, water stability and friability) revealed better performance of pea starch except pelletability in which guar gum performed best. Although not a single diet proved best in case of flotation time (Tf) and settling velocity (Vset) at varying lengths (6mm, 9mm and 12 mm). This finding indicates the significance of suitable binders for optimal water pollution and sustainable aquaculture. The use of these binders i.e. wheat gluten, pea starch and guar gum in fish feed pellets may also reduce dependence on synthetic binders and minimizes cost.

Resumo Uma das pragas mais comuns das palmeiras é o gorgulho vermelho da palmeira, Rhynchophorus ferrugineus Olivier. Cinco dietas artificiais foram avaliadas para criar RPW e facilitar seus estudos comportamentais e biológicos. O desenvolvimento de R. ferruginus foi estudado nas dietas artificiais testadas baseadas principalmente em pedaços de caule de cana-de-açúcar (1ª dieta; controle), abóbora-doce (2ª dieta), cana-de-açúcar + abóbora-doce (3ª dieta), batata-doce (4ª dieta) e cana-de-açúcar moída + batata-doce (5ª dieta) em sala de criação (28 ± 1 °C e 75 ± 5 UR%) na Faculdade de Agricultura do distrito de Benha. Os aspectos biológicos, pré-oviposição, oviposição, durações de larvas e pupas, a longevidade de machos e fêmeas adultos e o período de geração de R. ferrugineus foram todos estimados. Além disso, o impacto dessas dietas artificiais nas quantidades de proteínas totais, carboidratos e lipídios foi determinado nas larvas adultas. Os resultados obtidos mostraram que o inseto manifestou os menores períodos larval e pupal e a maior longevidade para machos e fêmeas quando a criação de R. ferruginus ocorreu em uma dieta artificial à base de batata-doce como uma forma bem-sucedida e econômica para a criação massal do gorgulho vermelho da palmeira em condições de laboratório. Larvas alimentadas com a dieta 4 (batata-doce) foram as que apresentaram a menor duração (114,80 dias), enquanto a 1ª dieta (pedaços de caule de cana-de-açúcar) foi a que apresentou o maior período (125,00 ± dias). Da mesma forma para a pupação e longevidade de machos e fêmeas, os períodos mais curtos resultaram da alimentação das larvas na 4ª dieta (14,65, 49,40 e 48,0 dias, respectivamente). Ao contrário, o período pupal mais longo foi relatado com a 5ª dieta (15,70 dias). A maior porcentagem de eclodibilidade dos ovos (96,53%) resultou da criação de larvas de R. ferruginus na 4ª dieta. As análises químicas das larvas adultas indicaram que os maiores teores de carboidratos totais (45,57 µg/g), lipídios (28,46 µg/g) e proteínas (20,01µg/g) foram obtidos no caso de larvas criadas na 1ª e 4ª dietas, respectivamente. Consequentemente, o desenvolvimento dos estádios de R. ferruginus foi ligeiramente menor tanto na 1ª quanto na 4ª dieta artificial. Assim, ambas foram dietas artificiais bem-sucedida e econômica para o desenvolvimento de RPW em condições de laboratório. Portanto, este estudo adicionou ingredientes alternativos valiosos para preparar substrato alimentar mais prático e econômico para a criação do gorgulho para auxiliar na proposta de seu manejo e conservação em plantações de palmeiras.

Abstract One of the most common palm pests is the red palm weevil, Rhynchophorus ferrugineus Olivier. Five artificial diets were evaluated to rear RPW, and to facilitate its behavioral and biological studies. The developmental of R. ferruginus was studied on the tested artificial diets based on primarily composed of sugarcane stem pieces (1st diet; control), sweet pumpkin (2nd diet), ground sugarcane + sweet pumpkin (3rd diet), sweet potato (4th diet) and ground sugarcane + sweet potato (5th diet) under rearing room (28 ± 1 °C and 75 ± 5 RH%) at Faculty of Agriculture in Benha district. The biological aspects, pre-oviposition, oviposition, larval & pupal durations, the longevity of male and female adults and the generation period of R. ferrugineus have all been estimated. Moreover, the impact of these artificial diets on the quantities of total proteins, carbohydrates and lipids were determined in the full-grown larvae. Obtained results showed that the insect manifested the shortest larval and pupal periods and the longest longevity for males and females when rearing of R. ferruginus took place on an artificial diet based on sweet potato as a successful and economical for mass rearing of the red palm weevil under laboratory conditions. Larvae fed on diet 4 (sweet potato) was exhibited the shortest duration (114.80 days), while 1st diet (Sugarcane stem pieces) was recorded the longest period (125.00 ± days). Similarly for pupation and both male and female longevity, the shortest periods resulted from larvae feeding on 4th diet (14.65, 49.40 and 48.0 days, respectively). Contrariwise, the longest pupal period was reported with 5th diet (15.70 days). The highest of eggs hatchability % (96.53%) resulted from the rearing nof R. ferruginus larvae on the 4th diet. Chemical analyses of the full-grown larva were indicated that the highest contents of total carbohydrates (45.57 µg/g), lipids (28.46 µg/g) and proteins (20.01µg/g) were obtained in case of larvae reared on 1st and 4th diets, respectively. Consequently, the development of R. ferruginus stages was slightly lower on both 1st and 4th artificial diets. So that, both of them were a successful and economic artificial diet for RPW development under laboratory conditions. Therefore, this study added valuable alternative ingredients to prepare more practical and economical feeding substrate for weevil rearing to help for proposal of its management and conservation in palm plantations.

ABSTRACT BACKGROUND: The identification and understanding of dietary factors and other characteristics that influence gestational weight gain can contribute to the formulation of strategies to promote healthy eating habits before and during pregnancy. OBJECTIVE: To investigate the association between dietary patterns, sociodemographic and obstetric characteristics, and health-related behaviors in pregnant women. DESIGN AND SETTING: A cross-sectional study was conducted on women undergoing prenatal care in the Unified Health System of Colombo, Paraná, Brazil, from February 2018 to September 2019. METHOD: A weekly food frequency questionnaire was administered, and dietary patterns were identified through factor analysis. Median regression models were constructed to identify the associations between dietary pattern scores and variables. RESULTS: Complete data were obtained from 495 pregnant women. Three dietary patterns were identified: 1) “healthy,” with higher factor loadings for the weekly consumption of raw vegetables, cooked vegetables, and fresh fruits; 2) “Western,” including soft drinks or artificial juice, candies, milk, and dairy products, and processed cold meat; and 3) “traditional,” beans and meat. Pregnant women aged 30 years or older (coefficient [Coef.] 0.86, 95% confidence interval [CI] 0.38–1.33) with moderate/intense physical activity (Coef. 0.32, 95% CI 0.02–0.62) had higher adherence to the “healthy” pattern. Adolescents and smokers adhered more to the “traditional” pattern (Coef. 0.17, 95% CI 0.01–0.33). CONCLUSION: Age, smoking status, and physical activity were associated with dietary patterns in pregnant women.

ABSTRACT. Cotesia flavipes parasitizes Diatraea saccharalis, a pest that causes major losses to sugarcane production. The mass production of C. flavipes and its subsequent release onto sugarcane is one form of biological control of D. saccharalis. An essential factor for successfully fighting this pest is the development of host diets that can increase the efficiency of C. flavipes production. Palm oil contains saturated fatty acids, unsaturated fatty acids, and polyunsaturated linoleic acid. However, little is known about the effects of palm oil on C. flavipes production in the laboratory. Different concentrations of palm oil were added to the D. saccharalis diet and its nutritional indices were analyzed. Subsequently, the production and sex ratio of C. flavipes were determined. Our results indicated that the addition of higher palm oil concentrations to an artificial diet generated a high relative consumption rate (RCR) in D. saccharalis, and consequently a high relative metabolic rate (RMR), which resulted in a lower production of the parasitoid. In contrast, the lowest palm oil concentration in the artificial diet generated a low RMR and resulted in high-efficiency conversion of ingested food (ECI), enabling D. saccharalis to yield more C. flavipes. This suggests that palm oil influences the quantity of D. saccharalis ingested, which determines the number of C. flavipes that will be generated. In this study, supplementation of a D. saccharalis diet with 0.25% palm oil increased the production of C. flavipes. Therefore, this level of palm oil supplementation can aid in the production of C. flavipes on a laboratory-scale. Further research, including increasing the number of parasitoids, must be performed to mass-produce the augmentative releases of C. flavipes to manage D. saccharalis.

ABSTRACT Understanding aspects of insect ecology is a key component for the applicability of control methods or pest resistance management. For instance, the comprehension of insect dispersal is crucial to determining insect gene flow and the maximum distance between refuge areas in Bt (Bacillus thuringiensis) crops. But, for such studies, insects need to be marked prior to release. Seeking to refine the technique of dispersion studies of the genetic material of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), this study aimed to determine the efficiency of water-soluble dyes for the internal marking of S. frugiperda immatures and adults via larval feeding, with emphasis on marking the spermatophore. Rhodamine B, Methylene Blue, Ponceau, Coomassie, and Eosin-Nigrosin were added to the larval artificial diet at concentrations of 0, 100, 200, 400, 600, 800, and 1000 ppm. Mortality and duration of the larval stage as well as the efficiency of marking internal structures of larvae and adults were evaluated. Rhodamine B and Methylene Blue increased the duration of the larval period, but the former caused higher mortality. The staining of the gut, hemolymph, and imaginal discs, in the larval phase, was observed for Rhodamine B, Methylene Blue, and Coomassie dyes. However, none of the dyes were efficient for marking spermatophores. Thus, the addition of these water-soluble dyes to the larval diet of S. frugiperda can mark internal structures of the larva, but not the adult. Therefore, these dyes have limited application once they may be used only for marking larvae. management instance Bacillus thuringiensis crops But release J.E.

ABSTRACT This study aimed to investigate the effects of different levels of vitamin D3 in broiler diets on performance and bone health. A total of 360 one-day old male Cobb500® broiler chicks were subjected to five treatments of different levels of vitamin D3 in diets during two rearing phases: 0 IU/kg in both phases; 625 IU/kg in starter and 500 IU/kg in grower phase (25% of commercial inclusion); 1,250 IU/kg in starter and 1,000 IU/kg in grower phase (50% of commercial inclusion); 1,875 IU/kg in starter and 1,500 IU/kg in grower phase (75% of commercial inclusion); and 2,500 IU/kg in starter and 2,000 IU/kg in grower phase (100% of commercial inclusion). The traits studied weekly were feed intake, body weight, feed conversion, and viability. At 21 and 35 days of age, tibiae and femurs were removed, dissected, and evaluated for dry matter (DM), ash (%MM), calcium (%Ca), phosphorus (%P) and breaking strength. At 35 days of age, the bones were subjected to histopathological analysis for macro- and microscopic morphological evaluation. Data were subjected to regression analysis, using α = 0.05. The variables of percentage %MM, %Ca, %P, and breaking strength experienced a positive linear effect up to the supplementation levels of approximately 25% of inclusion. The histopathological analysis found that the group that received the diet with 100% inclusion of vitamin D3 presented lesions compatible with osteopetrosis and tibial dyschondroplasia. The observed results showed that for isonutritive diets, reduced levels of vitamin D3 guaranteed performance during the evaluated period while the use of 100% of vitamin D3, as commonly used, can cause bone diseases and harm the welfare of broilers.

ABSTRACT BACKGROUND: Smoking and unhealthy diet are important risk factors for cardiovascular and metabolic diseases, contributing to public health crises. OBJECTIVE: To evaluate the consumption of natural/minimally processed and ultra-processed foods by Brazilian adults (18–59 years old) according to smoking status. DESIGN AND SETTING: Cross-sectional study of a representative population sample from 26 state capitals and the Federal District (Brazil-2018). METHODS: Data were obtained from Vigitel—Surveillance System for Risk and Protection Factors for Chronic Diseases by Telephone Survey. Participants were categorized as smokers, ex-smokers, and never smokers. Multinomial logistic regression was used for analyses. RESULTS: Of the 30,800 adults evaluated, 9.4% (95%CI: 8.7-10.2) were smokers and 16.5% (95%CI: 15.8-17.3) were ex-smokers. Smokers were less likely to consume fruit and natural juice, and more likely to consume soda or artificial juice (≥ 5 days/week) than ex-smokers and never smokers. Regarding the daily frequency of consumption, smokers were observed to be less likely to eat fruit more than 1 time/day and more likely to drink ≥ 3 cups/cans of soda/day. Compared to never smokers, smokers had a 42% higher chance of consuming ≥ 3 glasses of natural juice/day. On the day before the interview, fruit, milk, tubers, squash, and okra consumption were lower among smokers than non-smokers. Smokers were more likely to report consuming soft drinks, fruit juice, sauces, ready-made dishes, margarine, and sausages. CONCLUSION: Smokers had lower fruit consumption, and higher consumption of natural juices and ultra-processed foods. We highlight the need for strategies that encourage healthy eating and smoking cessation.

ABSTRACT The whitefly Aleurothrixus floccosus is one of the main foliar pests in citrus orchards at the Pica Oasis, Tarapacá Region. In this regard, the predator Clitostethus arcuatus naturally colonizes infested orchards; however, additional releases are required, making it necessary to rear them with artificial diets. The present study evaluated the effect of three artificial diets, two meridic and one oligidic, and natural diet (A. floccosus) on the postembryonic development and longevity of C. arcuatus under laboratory conditions. The results obtained indicate that embryonic development ranged bet^een 3-4 days (3.25 ± 0.44) with a survival at 100%. Furthermore, there were no significant differences. On the other hand, the four larval stages fed with A. floccosus took a total of 15.13 days [first larval stage (L1), 2.79 ± 0.41 days; second larval stage (L2) 3.63 ± 0.10 days; third larval stage (L3) 4.46 ± 0.51 days; and fourth larval stage (L4) 4.25 ± 0.53 days]; while thepupal stage lasted 4.75 ± 0.53 days. Thus, the development from egg to adult was 23.13 days. In contrast, L1 larvae fed with: meridic diet, meridic diet + tyrosine and oligidic diet recorded a mortality of 100%, without obtaining developed adult individuals. On the other hand, C. arcuatus fed with prey recorded a longevity of 53.13 days. Therefore, the natural diet was the most suitable for the devglopment of the predator. Howe^ver, the data obtained from artificial diets could be attributed to texture and/or consistency, since it is known that C. arcuatus larvae prefer feeding on eggs and nymphs of A. floccosus, requiring further studies of composition and texture diets; subsequently, to develop augmentative biological control programs, within the context of sustainable production and food security.

RESUMEN La mosquita blanca Aleurothrixus floccosus es una de las principales plagas foliares en huertos de cítricos del Oasis de Pica, región de Tarapacá. El depredador Clitostethus arcuatus coloniza naturalmente huertos infestados, sin embargo, se requieren liberaciones adicionales, y es necesaria su crianza basada en dietas artificiales. Este estudio evaluó el efecto de tres dietas artificiales, dos merídicas y una oligídica, y una natural (A. floccosus) sobre el desarrollo postembrionario y longevidad de C. arcuatus en condiciones de laboratorio. Los resultados indican que el desarrollo embrionario varió entre 3-4 días (3,25 ± 0,44) con una supervivencia del 100%. Además, no se registraron diferencias significativas. Por otro lado, los cuatro estadios larvales alimentados con A. floccosus demoraron en total 15,13 días [primer estadio larval (L1), 2,79 ± 0,41 días; segundo estadio larval (L2) 3,63 ± 0,10 días; tercer estadio larval (L3) 4,46 ± 0,51 días; y cuarto estadio (L4) 4,25 ± 0,53 días]. El estado de pupa duró 4,75 ± 0,53 días. Así, el desarrollo desde huevo hasta adulto fue de 23,13 días. En contraste, las larvas L1 alimentadas con dieta merídica, dieta merídica + tirosina y dieta oligídica registraron una mortalidad del 100%, sin obtener individuos adultos desarrollados. Por el contrario, C. arcuatus alimentados con presas mostraron una longevidad de 53,13 días. Según estos resultados, la dieta natural fue la más adecuada para el desarrollo del depredador. Sin embargo, los datos obtenidos de las dietas artificiales podrían atribuirse a la textura o consistencia, ya que las larvas de C. arcuatus prefieren depredar huevos y ninfas de A. floccosus. Por lo tanto, se necesitan estudios adicionales de composición y textura de dietas, para luego desarrollar programas de control biológico aumentativo, dentro del contexto de producción sostenible y seguridad alimentaria.

ABSTRACT Aim. To evaluate the effect of supplementation with distillers dried grains (DDGS) on in situ ruminal fermentation parameters by cattle grazing on forage sorghum. Materials and methods: Four Hereford heifers (793 ± 73 kg live weight) using a ruminal cannula, grazing on forage sorghum, with day-in enclosure and artificial shade, were part of a randomized crossover design study with two treatments: without supplementation (WOS) and with supplementation (WS), fed on DDGS. The experimental design comprised two 14-day periods (10 days for diet transition, and 4 days for measurements). Results: Supplementation did not affect DM consumption (P > 0.05), though it increased total consumption (P < 0.05). The WS treatment caused lower ruminal pH (6.17 vs. 6.55; (P < 0.05), and greater N_NH4 concentration (P < 0.05). The effective degradability of DM was 51.25%, the same as the other treatment (P > 0.05), whereas the effective NDF was lower in the WS treatment (P < 0.05). DM digestibility in WS was lower (65.75 vs. 60.75%), whereas NDF digestibility was 68.50 vs. 62.50%. Conclusion: DDGS supplementation decreased ruminal pH and raised N_NH4 concentrations, reducing the fiber’s effective degradability of DM and NDF.

RESUMEN Objetivo. Evaluar el efecto de la suplementación con granos secos de destilería más solubles (DDGS) sobre los parámetros de la fermentación ruminal in situ en vacunos pastoreando sorgo forrajero. Materiales y métodos: Cuatro novillos Hereford (793 ± 73 kg peso vivo) provistos de cánula ruminal pastoreando sorgo forrajero con encierro diurno y sombra artificial fueron asignados al azar en diseño crossover a dos tratamientos: sin suplemento (SS) y suplementados (CS), con DDGS. El diseño experimental comprendió dos períodos de 14 días (10 transición entre dietas; 4 de mediciones). Resultados: La suplementación no afectó el consumo de MS de forraje (P > 0,05), pero sí aumentó el consumo total (P < 0,05). El tratamiento CS presentó menor pH ruminal (6,17 vs. 6,55; (P < 0,05) y mayor concentración N_NH4 (P < 0,05). La degradabilidad efectiva de la MS fue 51,25% sin diferencias entre tratamientos (P > 0,05), mientras que la degradabilidad efectiva de la FDN fue menor CS (P < 0,05). La digestibilidad de la MS (65,75 vs 60,75%) y de la FDN (68,50 vs 62,50%) fue menor CS. Conclusión: La suplementación con DDGS disminuyó el pH ruminal y aumentó las concentraciones de N_NH4, disminuyendo la degradabilidad efectiva de la fibra y la digestibilidad de la MS y FDN.

Abstract This article aims to estimate the prevalence and weekly frequency of ultra-processed food consumption in six-year-old children and associated factors in a municipality in southern Brazil. Cross-sectional study with 956 children. Data were collected through interviews with mothers in the households. The outcomes were the consumption of candies, chewing gum, lollipops and chocolates; stuffed cookies; artificial juices; and soft drinks using the Índice de Alimentação Escolar (School Feeding Index). The independent variables were gender, type of school, education and maternal occupation, breastfeeding, duration of exclusive breastfeeding and the use of bottle. Bivariate analysis was performed using the chi-square test and the multivariate analysis using Poisson regression. In the multivariate analysis, the weekly prevalence of stuffed cookies consumption was 14% higher in students from public schools and 8% higher in children of mothers with less than eight years of schooling. Artificial juice and soft drink consumption was 7% and 8% higher in public school students respectively and 6% higher in bottle-fed children.

Resumen Los lepidópteros son uno de los grupos de organismos más grandes que existen, conocidos comúnmente como mariposas o polillas, los cuales en su estado larval son considerados como las plagas más dañinas en la agricultura. Larvas de lepidópteros fueron colectados del cultivo del higo y trasladadas bajo condiciones ambientales controladas y alimentadas bajo una dieta artificial. Se realizó una identificación de las larvas colectadas, así como la determinación de su ciclo de vida. Además, se determinó la fertilidad y eclosión de los huevos que ovipositaban los adultos en parejas. Se identificó al lepidóptero como Estigmene albida, insecto perteneciente a la superfamilia Noctuidae, familia Erebidae, el cual cuenta con poca información reportada en la literatura. El ciclo de vida consistió en 57 días, desarrollando cinco estadíos larvales con características similares a las reportadas para E. acrea, especie del mismo género y de mayor importancia como plaga agrícola. En promedio, las hembras que copularon y produjeron huevos viables pusieron 377,4 huevos por hembra, de los cuales se desarrollaron 222,4 larvas por hembra, siendo estos resultados menores a los reportados para E. acrea, pudiendo estas variables ser afectadas por la alimentación, la temperatura y la especie con la que se trabaja. Además, se logró colectar larvas de E. albida parasitadas por un taquínido identificado como Carcelia sp. En conclusión, este artículo brinda uno de los primeros reportes de E. albida atacando cultivos agrícolas y brinda información sobre su ciclo de vida y fertilidad. Además, es el primer reporte de este insecto atacando el cultivo del higo y de Carcelia sp. parasitando larvas de este lepidóptero.

Abstract Lepidoptera is one of the largest groups of organisms, known commonly as butterflies or moths, which in their larval state, are considered the most harmful agricultural plagues. Lepidoptera larvae were collected from a fig crop, transferred under controlled environmental conditions, and fed an artificial diet. An identification of the larvae collected was performed, as well as the determination of their life cycle. Additionally, the fertility and egg hatching rate were determined from the eggs laid by the adults placed in couples. The lepidopteran species was identified as Estigmene albida, an insect from the Noctuidae superfamily, Erebidae family, and with very few information reported in the literature to date. The life cycle consisted of 57 days, developing 5 larval stages, with similar characteristics to those reported for E. acrea, a species from the same genus with more known importance as a crop plague. On average, the females that mated and laid viable eggs, placed 377.4 eggs, from which 222.4 per female developed larvae. These results were less than those reported for E. acrea; however, these variables could have been affected by the diet, the temperature and the species worked with. Also, it was possible to collect larvae from E. albida parasited with the tachinidae Carcelia sp. In conclusion, this study provides one of the first reports of E. albida affecting crops and provides information of their life cycle and fertility. It is also the first report of this insect affecting specifically a fig crop and of Carcelia sp. parasiting larvae of this lepidoptera.

Resumen Objetivos: informe de expertos para valorar la realidad de la pérdida de masa muscular en las personas con diabetes mellitus 2 (DM2) y proponer, en base a la evidencia de la bibliografía y la experiencia clínica, cómo debería ser el abordaje clínico de esta comorbilidad. Método: estudio cualitativo de opinión de expertos mediante metodología nominal. Se realizó una búsqueda bibliográfica sobre diabetes y músculo que se remitió a un grupo multidisciplinar de 7 expertos que, en reunión presencial, discutieron sobre diversos aspectos del papel de la masa muscular en la DM2. Resultados: la masa muscular debe tenerse en cuenta dentro del cuadro clínico del paciente con DM2. Repercute enormemente sobre la funcionalidad y la calidad de vida del paciente y es tan importante como el adecuado control metabólico de la DM2. Conclusión: además de la terapia farmacológica y la dieta adaptada, es imprescindible un patrón de actividad física aeróbica y de fuerza para el mantenimiento de la masa y la función muscular en el paciente diabético. En situaciones particulares, una suplementación oral artificial específica para el cuidado del músculo podría mejorar la situación de desnutrición y baja masa muscular. Medidas como el test de la velocidad de marcha, el test de la silla o el cuestionario SARC-F, junto a un índice de Barthel, son un primer paso para diagnosticar un deterioro relevante sobre el que actuar en el paciente DM2. Este documento pretende resolver algunos interrogantes sobre la importancia, la valoración y el control de la masa muscular en la DM2.

Abstract Objectives: an expert report is presented on the situation of loss of muscle mass in people with type 2 diabetes mellitus (T2DM), with a proposal of what the clinical approach to this comorbidity should be, based on the evidence from the literature and clinical experience. Method: a qualitative expert opinion study was carried out using the nominal approach. A literature search on diabetes and muscle was made and submitted to a multidisciplinary group of 7 experts who through a face-to-face meeting discussed different aspects of the role of muscle mass in T2DM. Results: muscle mass must be taken into account in the clinical context of patients with T2DM. It has an enormous impact on patient function and quality of life, and is as important as adequate metabolic control of T2DM. Conclusion: in addition to drug therapy and diet adjustments, aerobic and strength activities are essential for maintaining muscle mass and function in diabetic patients. In concrete situations, artificial oral supplementation specific for muscle care could improve the situation of malnutrition and low muscle mass. Measures such as the walking speed test, chair test, or the SARC-F questionnaire, together with the Barthel index, constitute a first step to diagnose relevant impairment requiring intervention in patients with T2DM. This document seeks to answer some questions about the importance, assessment, and control of muscle mass in T2DM.

Resumo Doru luteipes (Scudder, 1876) é um predador onívoro, que encontra na planta do milho diferentes recursos alimentares: ovos de Spodoptera frugiperda (J.E. Smith, 1797), uredósporos de Puccinia polysora (Underw, 1897) e pólen. Para definição da relevância desse predador como agente de controle biológico, conhecer a sobrevivência e preferência alimentar é essencial. Nós hipotetizamos que o comportamento de forrageamento e a capacidade de predação de D. luteipes podem ser afetados quando uma mesma planta oferece ovos, uredósporos e pólen, concomitantemente. A sobrevivência de D. luteipes na fase de ninfa e sua preferência entre os recursos alimentares, frequentemente disponíveis nas plantas de milho, foram determinados. Para verificar a sobrevivência de D. luteipes, ninfas recém eclodidas foram alimentadas exclusivamente com 1- uredósporos de P. polysora, 2- ovos de S. frugiperda, 3- pólen de milho, 4- combinação de uredósporos + ovos e 5- dieta artificial (controle). Em outro experimento, ninfas e adultos de D. luteipes com 24 e 48 horas de jejum foram liberadas individualmente, em recipientes contendo quatro dietas: 1- uredósporos de P. polysora, 2- ovos de S. frugiperda, 3- pólen de milho, 4- dieta artificial e mantidas durante 10 min, sendo avaliados a escolha pelo alimento e o tempo de alimentação. A alimentação exclusiva com ovos de S. frugiperda ocasionou baixa sobrevivência das ninfas (8%), porém a combinação de uredósporos de P. polysora + ovos de S. frugiperda possibilitou sobrevivência de 58,3%. D. luteipes preferiu se alimentar durante o período noturno e as maiores proporções de escolhas das ninfas e dos adultos ocorreram no pólen e na dieta, sendo que os adultos gastaram mais tempo se alimentando de pólen. Estas descobertas indicam que as escolhas tróficas de D. luteipes são relevantes para compreender sua contribuição como agente de controle de insetos-praga e doença fúngicas em milho.

Abstract Doru luteipes (Scudder, 1876) is an omnivorous predator that finds different food resources in the corn plant: eggs of Spodoptera frugiperda (J.E. Smith, 1797), uredospores of Puccinia polysora (Underw, 1897), and pollen. Knowing the survival and food preferences of this predator is essential to define its relevance as a biological control agent. We hypothesize that the foraging behavior and predatory capacity of D. luteipes may be affected when several food resources, especially eggs of S. frugiperda, uredospores of P. polysora, and pollen are concurrently in the same plant. The survival of D. luteipes in the nymph stage and their preference among food resources, often available in corn plants, were determined. To verify the survival of D. luteipes, newly hatched nymphs were fed exclusively with 1- uredospores of P. polysora, 2- eggs of S. frugiperda, 3- corn pollen, 4- a combination of uredospores + eggs, and 5- artificial diet (control). In another experiment, nymphs and adults of D. luteipes with 24 and 48 hours of fasting were individually released in the center of a container with four diets: 1- uredospores of P. polysora, 2- eggs of S. frugiperda, 3- corn pollen, 4- artificial diet, and maintained for 10 minutes, to evaluate the food choice and feeding time. The exclusive feeding with S. frugiperda eggs caused low nymph survival (8%), but the combination of P. polysora uredospores + S. frugiperda eggs allowed 58.3% survival. D. luteipes preferred feeding during the nighttime and the most significant proportions of choices by nymphs and adults were for pollen and diet, with adults spending more time eating pollen. These findings indicate that the trophic choices of D. luteipes are relevant to understand its contribution as an agent to control pest insects and fungal diseases in corn.

Abstract Projects on river basin integration are keen social-economical drivers in dry regions like the Brazilian semiarid, however, there are concerning ecological impacts implied in those projects. In a long-term analysis, ichthyofauna colonization and spread through the East Axis of the São Francisco River Integration Project (SFIP) was monitored to assess possible impacts on the receiving Paraíba River basin. The fish were collected semiannually (2012 to 2021) from 19 sites in the São Francisco (SF) and Paraíba (PB) basins. A total of 69 fish species were recorded, with distinct fish assemblages between SF (n = 50), PB (n = 35), and the SFIP artificial reservoirs (n = 25). The SFIP reservoirs were colonized by species from the donor basin (SF). In a pioneer finding, Anchoviella vaillanti was recorded for the first time in the receiving basin and it is in the process of establishment. The two SF species that reached PB through the SFIP canals (A. vaillanti and Moenkhausia costae) may be using their year-round reproduction and wide diet to successful spread and colonize the new environment. Since we detected species with potential to reach the receiving basin and became invasives, the implementation of barriers to contain their spread are recommended. socialeconomical social economical semiarid however projects longterm long term analysis (SFIP 2012 (201 2021 1 (SF (PB basins 6 n 50, 50 , 50) 35, 35 35) 25. 25 . 25) SF. finding establishment A.

Resumo Projetos de integração de bacias hidrográficas são socialmente importantes em regiões como o semiárido brasileiro, porém há impactos ecológicos preocupantes implícitos nesses grandes projetos de infraestrutura. A colonização e dispersão da ictiofauna pelo Eixo Leste do Projeto de Integração do Rio São Francisco (PISF) foi monitorada para avaliar possíveis impactos na bacia receptora do rio Paraíba do Norte. Os peixes foram coletados semestralmente (2012 a 2021) em 19 locais das bacias do São Francisco (SF) e Paraíba (PB). Foram registradas 69 espécies de peixes, sendo 50 nos pontos do SF, 25 nos reservatórios artificiais ao longo do PISF e 35 nos pontos do PB. As assembleias de peixes das bacias do SF, PB e dos reservatórios do PISF foram significativamente distintas. Os reservatórios do PISF foram colonizados por espécies provenientes da bacia doadora (SF). Anchoviella vaillanti foi registrada pela primeira vez na bacia receptora do PB e está em processo de estabelecimento. As duas espécies do SF que chegaram ao PB pelos canais do PISF (A. vaillanti e Moenkhausia costae) apresentaram dieta e estratégias reprodutivas que permitem o sucesso na disseminação e colonização. Uma vez que foram detectadas espécies com potencial de atingir a bacia receptora, recomenda-se o monitoramento e manejo contínuos. brasileiro infraestrutura (PISF Norte 2012 (201 2021 1 (SF .
