Resumo Introdução: A deficiência de crescimento na doença renal crônica está relacionada à elevada morbidade e mortalidade. O retardo do crescimento nessa doença é multifatorial. É fundamental conhecer os fatores modificáveis e estabelecer estratégias para melhorar o atendimento às crianças afetadas. Objetivos: Descrever padrões de crescimento em crianças com DRC e fatores de risco associados à baixa estatura. Métodos: Analisamos retrospectivamente dados antropométricos e epidemiológicos, peso ao nascer, prematuridade e níveis de bicarbonato, hemoglobina, cálcio, fosfato, fosfatase alcalina e paratormônio de crianças com DRC estágios 3–5, não submetidas a diálise, acompanhadas por pelo menos um ano. Resultados: Incluímos 43 crianças, a maioria meninos (65%). O escore z médio de altura/comprimento/idade das crianças no início e no acompanhamento foi de –1,89 ± 1,84 e –2,4 ± 1,67, respectivamente (p = 0,011). Cinquenta e um por cento das crianças apresentaram baixa estatura, e essas crianças eram mais jovens que aquelas com estatura adequada (p = 0,027). Níveis de PTH no início do acompanhamento correlacionados com escore z de altura/comprimento/idade. Uma subanálise com crianças menores de cinco anos (n = 17) mostrou que 10 (58,8%) delas apresentaram déficit de desenvolvimento e escore z de peso/idade mais baixo (0,031) e escore z de IMC/idade mais baixo (p = 0,047). Conclusão: Crianças, especialmente mais jovens, com DRC, que não estavam em diálise, apresentaram elevada prevalência de baixa estatura. Níveis de PTH foram correlacionados com escore z de altura, e deficiência de crescimento foi associada a pior estado nutricional. Portanto, é essencial monitorar o crescimento dessas crianças, controlar o hiperparatireoidismo e fornecer suporte nutricional.

Abstract Introduction: Growth failure in chronic kidney disease is related to high morbidity and mortality. Growth retardation in this disease is multifactorial. Knowing the modifiable factors and establishing strategies to improve care for affected children is paramount. Objectives: To describe growth patterns in children with chronic kidney disease and the risk factors associated with short stature. Methods: We retrospectively analyzed anthropometric and epidemiological data, birth weight, prematurity, and bicarbonate, hemoglobin, calcium, phosphate, alkaline phosphatase, and parathormone levels of children with stages 3–5 CKD not on dialysis, followed for at least one year. Results: We included 43 children, the majority of which were boys (65%). The mean height/length /age z-score of the children at the beginning and follow-up was –1.89 ± 1.84 and –2.4 ± 1.67, respectively (p = 0.011). Fifty-one percent of the children had short stature, and these children were younger than those with adequate stature (p = 0.027). PTH levels at the beginning of the follow-up correlated with height/length/age z-score. A sub-analysis with children under five (n = 17) showed that 10 (58.8%) of them failed to thrive and had a lower weight/age z-score (0.031) and lower BMI/age z-score (p = 0.047). Conclusion: Children, particularly younger ones, with chronic kidney disease who were not on dialysis had a high prevalence of short stature. PTH levels were correlated with height z-score, and growth failure was associated with worse nutritional status. Therefore, it is essential to monitor the growth of these children, control hyperparathyroidism, and provide nutritional support.

Resumen Introducción. En agricultura orgánica, se utilizan abonos verdes y biocontroladores como métodos de fertilización y control de plagas. Sin embargo, la aplicación independiente de estos incrementa los costos de producción. Se propone una presentación peletizada que permita la aplicación conjunta de ambos insumos. Objetivo. Evaluar el efecto de Mucuna pruriens (L.) DC. peletizada e inoculada con Trichoderma harzianum Rifai en el aporte nutricional, el rendimiento agrícola y la regulación de Fusarium oxysporum f. sp. lycopersici en tomate (Solanum lycopersicum L.). Materiales y métodos. El experimento se ejecutó el año 2022 en Tablón del Guarco, Cartago, Costa Rica, bajo un diseño de bloques completos al azar con siete tratamientos y siete repeticiones. Se aplicaron dos formulaciones (A y B) de biopélet (M. pruriens + zeolita + T. harzianum) en tres dosificaciones (15, 30, 50 g/planta). La adición de T. harzianum se efectuó a razón de 5 g por cada kilo del biopélet. Se realizaron aplicaciones cada 15 días por tratamiento para un total de ocho aplicaciones. Se inoculó F. oxysporum (100 mL/planta con una concentración de 1 x 103 UFC) a la siembra. Resultados. La aplicación del biopélet mostró un rendimiento y peso de frutos de primera calidad similar al testigo comercial. En frutos de segunda y tercera calidad, no hubo diferencias significativas entre tratamientos. La eficiencia en el control de F. oxysporum alcanzó el 97,6 % con biopélet. Esta enmienda aumentó los niveles de Carbono, Nitrógeno y materia orgánica en el suelo e influenció el contenido nutricional en el follaje a los 60 días después de la siembra. Conclusiones. El biopélet tiene la capacidad de realizar aportes químicos y orgánicos al suelo, por lo cual mejora la nutrición del cultivo del tomate. Los resultados sugieren además que es una alternativa de biocontrol contra F. oxysporum y compatible con T. harzianum.

Abstract Introduction. In organic agriculture, green manures and biocontrols are used as methods for fertilization and pest control. However, their independent application of these inputs increases production costs. A pelletized formulation is proposed to allow simultaneous application of both inputs. Objective. To evaluate the effect of pelletized Mucuna pruriens (L.) DC. inoculated with Trichoderma harzianum Rifai on nutritional intake, agricultural yield, and regulation of Fusarium oxysporum f. sp. lycopersici in tomato (Solanum lycopersicum L.). Materials and methods. The experiment was carried out in 2022 in Tablón del Guarco, Cartago, Costa Rica, using a randomized complete block design with seven treatments and seven repetitions. Two formulations (A and B) of biopellet (M. pruriens + zeolite + T. harzianum) were applied at three dosages (15, 30, 50 g/plant). T. harzianum was added at a rate of 5 g/kg of biopellet. Applications of each treatment were conducted every 15 days for a total of eight applications. At the time of planting, F. oxysporum was inoculated (100 mL/plant with a concentration of 1 x 103 CFU). Results. The application of biopellet achieved a yield and weight of high-quality fruits similar to the commercial control. There were no significant differences among treatments for second and third-quality fruits. The technical efficiency in controlling F. oxysporum reached 97.6 % with biopellet. This amendment increased the levels of Carbon (C), Nitrogen (N), and organic matter in the soil and affected the nutritional content of the plant foliage in the first 60 days after sowing. Conclusions. The biopellet has the capacity to make chemical and organic contributions to the soil, which improves the nutrition of the tomato crop. It could be also a biocontrol alternative against F. oxysporum and compatible with T. harzianum.

Objetivo. Evaluar la absorción de cadmio mediante la técnica de omisión de macronutrientes en seis suelos del Ecuador y su efecto sobre el desarrollo vegetativo del cultivo de arroz. Materiales y métodos. El ensayo se realizó en la Estación Experimental Tropical Pichilingue del Instituto Nacional de Investigaciones Agropecuarias, Ecuador, durante el año 2018. Se estudiaron nueve tratamientos 1) Sin fertilización y sin Cd (testigo 1), 2) sin fertilización y con Cd (Testigo 2), 3) Fertilización completa y seis tratamientos de omisión de un nutriente a la vez, se usó un diseño de experimentos de bloques completamente al azar, parcelas divididas y tres repeticiones. Las variables evaluadas fueron las relacionadas a la producción de materia seca en raíz y parte aérea. Para la comparación entre medias, se utilizó la prueba de Tukey (p<0,05). Resultados. Las omisiones de los nutrientes (N y P) llevaron a la reducción de la absorción del Cd, que disminuyó la producción de materia seca, en particular en los suelos muy ácidos o alcalinos como en Sucumbíos (pH 4) y Guayas (pH 7,9), respectivamente. Conclusiones. La absorción de cadmio en plantas de arroz se redujo en mayor medida con la omisión de los macronutrientes N y P, principalmente en los suelos de Sucumbíos, Los Ríos, El Oro y Manabí, afectando también la omisión de nutrientes a la producción de materia seca y los rendimientos, observándose además que un pH por debajo de 5 o superior a 7,9 afecta la absorción de cadmio en los suelos estudiados

Abstract Introduction. The soil and climatic conditions of Ecuador are ideal for rice cultivation, yields are higher than the world average, but agronomic management leads to an increase of cadmium in the soil, which can reach the grain by translocation, which affects its safety. Objetive. To evaluate the absorption of cadmium through the omission of macronutrients technique in six soils of Ecuador and its effect on the vegetative development of rice crops. Materials and methods. The trial was carried out at the Pichilingue Tropical Experimental Station of the National Institute of Agricultural Research, Ecuador, during 2018. Nine treatments were studied: 1) Without fertilization and without Cd (control 1), 2) without fertilization and with Cd (Control 2), 3) Complete fertilization and six omission treatments of one nutrient at a time, a completely randomized block design of experiments, divided plots and three repetitions was used. The variables evaluated were those related to the production of dry matter in the root and aerial part. For the comparison between means, the Tukey test was used (p<0.05). Results. Nutrients omissions (N and P) led to reduced Cd absorption, which decreased dry matter production, particularly in very acidic or alkaline soils such as in Sucumbíos (pH 4) and Guayas (pH 7, 9), respectively. Conclusions. The absorption of cadmium in rice plants was reduced to a greater extent with the omission of the macronutrients N and P, mainly in the soils of Sucumbíos, Los Ríos, El Oro and Manabí, the nutrient omission technique also affecting the production of dry matter and yields, also observing that a pH below 5 or higher than 7.9 affects the absorption of cadmium in the soils studied.

Summary: Soil solution (SS) constitutes the volume from which plant roots extract dissolved nutrients. Despite its importance, the impact of its composition due to the application of organic amendments has been relatively little studied. The objective of this research was to study the impact of humic acids (HA) and chitosan (Cs) on the concentration of minerals in the SS, as well as their effect on the yield of the cabbage crop (Brassica oleracea L.). Under greenhouse conditions with calcareous soil, two doses of HA were applied (200 and 500 kg ha-1), as well as 50 and 150 kg ha-1 of Cs in a targeted manner. From the SS, 22 samples were taken non-destructively from the root zone once a week. The results of mineral content in the soil solution and mineral content on the biomass did not present significant differences, however, it was noted that the Cs50 treatment stimulated 41% higher plant biomass than the control (P ≤ 0.5, Tukey). It is concluded that Cs and HA do not significantly impact the ionic content of the SS or the mineral content of the biomass, although they do stimulate the yield.

Resumen: La solución del suelo (SS) constituye el volumen de donde las raíces de las plantas extraen los nutrientes disueltos. A pesar de su importancia, el impacto de su composición por la aplicación de enmiendas orgánicas se encuentra relativamente poco estudiado. El objetivo de esta investigación fue estudiar el impacto de los ácidos húmicos (AH) y quitosán (Cs) sobre la concentración de los minerales en la SS, así como su efecto en el rendimiento del cultivo de col (Brassica oleracea L.). En condiciones de invernadero con suelo calcáreo se aplicaron dos dosis de AH (200 y 500 kg ha-1), así como 50 y 150 kg ha-1 de Cs de forma dirigida. De la SS se tomaron 22 muestras en forma no destructiva de la zona de la raíz una vez por semana. Los resultados del contenido mineral en la solución del suelo y del contenido mineral en la biomasa no presentaron diferencias significativas, no obstante, se apreció que el tratamiento Cs50 estimuló 41% la biomasa vegetal superior al testigo (P ≤ 0.5, Tukey). Se concluye que el Cs y AH no impactan significativamente el contenido iónico de la SS ni el contenido mineral de la biomasa, aunque si estimulan el rendimiento.

Summary: In different trials have shown that the use of both vermicompost (VC) and plastic mulch has favored the yield and productivity of a large number of crops. The purpose of our study was to compare synthetic fertilization vs the incorporation of VC on the development of triploid watermelon with plastic mulch in the spring-summer 2019 agricultural cycle at the experimental field of the Universidad Autónoma Agraria Antonio Narro. The treatments evaluated, each with three repetitions, were: exploratory application of VC, at a rate of 30 and 60 Mg ha-1, and as a control, the regional recommendation 240-120-00 ha-1 (N-P-K). The sowing was carried out in planting beds of 2 × 8 m (width and length, respectively) covered with black plastic. The sowing of the triploid watermelon seeds of the Crunchy Red variety, was carried out in Styrofoam trays with 200 cavities filled with Peat Moss. When the seedlings had two to three true leaves, they were transplanted 1.0 m apart on planting beds of 2 × 8 m (width and length, respectively) covered with black plastic. For the supply of water, drip irrigation was used. To evaluate the effect of the treatments, a completely randomized experimental design was used, the DMS0.05 test was applied for comparisons of the means. Due to the effect of the treatments evaluated, five of the variables studied: equatorial and polar diameters, pulp thickness, soluble solids and fruit weight presented highly significant differences, while yield registered a significant difference. The highest yield of 29 932 Mg ha-1 was recorded with the incorporation of 60 Mg ha-1 of VC confirming that this natural fertilizer was able to satisfy the nutritional needs of triploid watermelon without synthetic fertilization.

Los tratamientos evaluados, cada uno con tres repeticiones, fueron: aplicación exploratoria de VC, a razón de 30 y 60 Mg ha-1, y como testigo, la recomendación regional 240-120-00 ha-1 (N-P-K). La siembra de semillas de sandía triploide, variedad Crunchy Red, se realizó en bandejas de unicel de 200 cavidades, rellenas con Peat Moss, cuando las plántulas tuvieron de dos a tres hojas verdaderas se realizó el trasplante, colocándolas a 1.0 m, entre éstas, sobre camas de siembra, de 2 × 8 m (ancho y largo, respectivamente) cubiertas con plástico negro. Para el suministro de agua se utilizó riego por cintilla. Para evaluar el efecto de los tratamientos se utilizó un diseño experimental completamente al azar, mientras que para las comparaciones de las medias se aplicó la prueba DMS0.05. Debido al efecto de los tratamientos evaluados cinco de las variables estudiadas: diámetros polar y ecuatorial, espesor de pulpa, sólidos solubles y peso del fruto registraron diferencias altamente significativas, mientras que el rendimiento presentó diferencia significativa. El mayor rendimiento de 29 932 Mg ha-1 se registró con la aplicación de 60 Mg ha-1 de VC, confirmándose que este producto logró cubrir la demanda nutritiva de la sandía triploide sin fertilización sintética.

RESUMO A salinidade desencadeia uma série de efeitos nocivos na nutrição mineral das plantas, o que causa perda na produção. O objetivo deste estudo foi avaliar os efeitos do uso de água salobra com irrigação por gotejamento por pulso e contínua no acúmulo de nutrientes na cultura de amendoim (Arachis hypogaea). O delineamento experimental utilizado foi o de blocos casualizados sob esquema fatorial (6 × 2), constituído por seis níveis de condutividade elétrica da água de irrigação (CEa: 0,2; 1,6; 2,8; 4,0; 5,2 e 6,4 dS m-1) e dois tipos de manejo da irrigação (por pulsos e contínua) com quatro repetições. Após 63 dias de semeadura, o acúmulo e a exportação de macronutrientes, sódio e cloro foram quantificados. A irrigação por pulso mitigou os efeitos deletérios da salinidade sobre a cultura do amendoim e proporcionou um maior acúmulo de nutrientes pela cultura em relação a irrigação contínua. A ordem decrescente de acúmulo de nutrientes pelas plantas sob irrigação por pulso e contínua foi: K > N > Ca > Mg > P > S. A irrigação por pulso é eficaz para mitigar os efeitos do uso de água salobra na cultura do amendoim. produção Arachis hypogaea. hypogaea . hypogaea) 6 ( 2, 2 , 2) CEa (CEa 0,2 02 0 1,6 16 1 2,8 28 8 4,0 40 4 52 5 5, 64 6, m1 m m-1 repetições semeadura macronutrientes quantificados S 0, 1, 4, m-

ABSTRACT High salinity levels trigger harmful effects on plant mineral nutrition, causing production losses. The objective of this study was to evaluate effects of using pulse or continuous drip irrigation with brackish water on the accumulation and exportation of nutrients in peanut (Arachis hypogaea) crops. A randomized block experimental design with four replications was used, in a 6×2 factorial arrangement consisting of six levels of electrical conductivity of irrigation water (ECw: 0.2, 1.6, 2.8, 4.0, 5.2, and 6.4 dS m-1) and two irrigation regimes (pulse and continuous). Accumulation and exportation of macronutrients, sodium, and chloride were quantified at 63 days after sowing. Pulse irrigation mitigated the harmful effects of high salinity levels on peanut crops and promoted greater nutrient accumulation by plants compared to continuous irrigation. The descending order of nutrient accumulation by plants under pulse and continuous irrigation was: K > N > Ca > Mg > P > S. Pulse irrigation is effective in mitigating the detrimental effects of using brackish water on peanut crops. nutrition losses Arachis hypogaea used 62 6 2 6× ECw (ECw 02 0 0.2 16 1 1.6 28 8 2.8 40 4 4.0 52 5 5.2 64 6. m1 m m-1 continuous. . continuous) macronutrients sodium sowing S 0. 1. 2. 4. 5. m-

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN. Paulo 2117108 2 117 108 2,117,10 SISVAN, SISVAN , (SISVAN) 748551 748 551 748,55 VIVALEITE. .

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas.

ABSTRACT Custard apple (Annona squamosa L.) is a sensitive fruit crop to salinity. One of the alternatives to minimize the deleterious effects of salt stress is adopting mineral fertilization management practices, promoting increased crop tolerance to salts. Therefore, the objective of the present study was to evaluate NPK doses to mitigate salt stress in custard apple seedlings irrigated with saline wastewater. The experiment was performed in a greenhouse, adopting a randomized block design in a 3 × 5 factorial scheme, corresponding to three irrigation waters (local-supply water of 0.53 dS m-1 electrical conductivity (control); desalination reject of 3.5 dS m-1; fish farming effluent of 3.5 dS m-1) and five proportions of the NPK recommendation (25, 50, 75, 100, and 125% of the fertilization recommendation), with four replicates. The growth, biomass accumulation, and nutrients were evaluated. Irrigation with desalination reject, and fish farming effluent restricted the growth of custard apple seedlings, regardless of the NPK dose used. The ionic homeostasis of seedlings irrigated with desalination reject and fish farming effluent is optimized by fertilization with 50% of the NPK recommendation corresponding to 50, 150, and 75 mg of N, P2O5, and K2O dm-3, respectively. For the production of seedlings irrigated with local-supply water, the dose of 75% NPK, corresponding to 75, 225, and 112.5 mg of N, P2O5, and K2O dm-3, respectively, is recommended. Annona L.

RESUMO A pinheira (Annona squamosa L.) é uma frutífera sensível à salinidade. Uma das alternativas para minimizar os efeitos deletérios do estresse salino é a adoção de práticas de manejo da fertilização mineral, promovendo o aumento da tolerância da cultura aos sais. Portanto, o objetivo foi avaliar as doses de NPK para mitigar o estresse salino em mudas de pinheira irrigadas com água residual salina. O experimento foi realizado em casa de vegetação, em delineamento de blocos casualizados, em esquema fatorial 3 × 5, correspondendo a três águas de irrigação (água de abastecimento local de 0,53 dS m-1 de condutividade elétrica (controle); rejeito salino da dessalinização de 3,50 dS m-1; efluente de piscicultura de 3,50 dS m-1) e cinco proporções da recomendação de NPK (25, 50, 75, 100 e 125% da recomendação de fertilização), com quatro repetições. O crescimento, acúmulo de biomassa e nutrientes foram avaliados. A irrigação com rejeito salino e efluente de piscicultura restringe o crescimento das mudas de pinha, independentemente da dose de NPK utilizada. A homeostase iônica das mudas irrigadas com rejeito salino e efluente de piscicultura é otimizada pela fertilização com 50% da recomendação de NPK correspondente a 50, 150 e 75 mg de N, P2O5 e K2O dm-3, respectivamente. Para a produção de mudas irrigadas com água de abastecimento local, recomenda-se a dose de 75% de NPK, correspondente a 75, 225 e 112,5 mg de N, P2O5 e K2O dm-3, respectivamente. Annona L.

ABSTRACT Background Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is associated with significant morbidity and mortality. We present an alternative technique that preserves the complete mesenteric vascularization during the isolation of the intestinal segment used in ICUD, including distal vessels. This approach aims to minimize the risk of ischemia in both the ileal anastomosis and the isolated loop at the diversion site. Methods This cohort study included 31 patients, both male and female, who underwent RARC with ICUD from February 2018 to November 2023, performed by a single surgeon. Intraoperative and postoperative complications data were retrieved for analysis, employing our proposed mesentery-sparing technique in all cases. The primary endpoint was the incidence of intraoperative and postoperative complications directly attributable to the mesentery-sparing approach in ICUD. Secondary endpoints included other postoperative variables not directly related to mesentery preservation, such as the incidence of postoperative ileus requiring parenteral nutrition and the duration of hospitalization. Results None of the patients experienced intraoperative or postoperative complications directly related to mesentery-sparing, such as intestinal fistulae or internal hernias. The median duration of hospitalization was 6 days, and postoperative ileus necessitating total parenteral nutrition occurred in 19% of the patients. Minor complications (Clavien–Dindo grades I-II) accounted for 27.6% of the cases and major complications (grades III-V) accounted for 20.6%. Conclusion The mesentery-sparing technique outlined herein offers an alternative method for preserving the vascularization of intestinal segments and reducing the risk of intestinal complications in ICUD during RARC.

Abstract Objective: To examine the mental health status and related factors in children and adolescents, and to assess age groups and sexes differences in factors influencing mental health. Methods: This cross-sectional study was performed on Chinese children aged 6-18 years from November 2021 to January 2022. Mental health difficulties were accessed by the Strengths and Difficulties Questionnaire. Multivariate logistic regression was used to analyze factors associated with mental health status. Multiple linear regression was used to evaluate factors associated with the scores of the Strengths and Difficulties Questionnaire. Results: The prevalence of mental health difficulties was 12.98% (n =1348). Age (OR, 0.909, [95%CI, 0.830-0.996]), sex (OR, 1.424, [95%CI, 1.033-1.963]) and screen time on weekdays (“≥2” h/d vs “< 1” h/d: OR, 2.001, [95%CI, 1.300-3.080]) were related factors for mental health difficulties. For children (year ≤ 12), the strongest related factor for mental health difficulties was screen time on weekdays (“≥ 2” h/d vs “< 1” h/d: OR, 1.821 [95%CI, 1.203-2.755]). The risk of mental health difficulties in females with ≥ 2 h/d screen time on weekends was 3.420 times higher than those with < 1 h/d (OR, 3.420, [95%CI, 1.923-6.081]). Conclusion: The prevalence of mental health difficulties among children and adolescents was relatively high. The lower age, female sex and excessive screen time were associated with a higher risk of mental health difficulties. The factors influencing mental health varied by different age groups and sexes. Thus, specific measures for different age groups and sexes should be adopted to mitigate the impact.

Abstract Objective: To evaluate exclusive breastfeeding at discharge and hospital length-of-stay in pre-term infants undergoing or not the Kangaroo-Mother Care Method (KMC). Methods: A retrospective cohort study was conducted including preterm infants < 1800 g admitted to the neonatal unit of a KMC reference center. The infants were grouped into the KMC group and the non-KMC group. Multiple logistic and Poisson regressions were performed to evaluate the association between the KMC and two outcomes, exclusive breastfeeding at discharge, and hospital length-of-stay, adjusted for potential confounders. Results: 115 mother-infant dyads were included, 78 in the KMC group and 37 in the non-KMC group. In the bivariate analysis, the KMC group had a lower prevalence of maternal adverse conditions (6% vs. 32%, p < 0.001), a higher number of prenatal visits (median 6 vs. 3.5, p < 0.001), higher gestational ages (median 32 vs. 31 weeks, p < 0.05), higher birth weights (median 1530 vs. 1365 g, p < 0.01), a lower prevalence of necrotizing enterocolitis (3.8% vs. 16.2%, p < 0.05), parenteral nutrition (50% vs. 73%, p < 0.05), and deep vascular access (49.7% vs. 78.4%, p < 0.01), a higher prevalence of exclusive breastfeeding (65% vs. 8%, p < 0.001) and a shorter length of hospital stay (median 28 vs. 42 days, p < 0.001). In the multiple regression analysis, the KMC group was 23 times more likely to be exclusively breastfed at discharge (OR = 23.1; 95% CI = 4,85–109,93) and had a 19% reduction in the hospital length-of-stay (IDR = 0.81; 95% CI = 0.76–0.86) compared to the non-KMC group. Conclusions: The KMC is associated with better short-term neonatal outcomes and should be encouraged in all Brazilian maternity hospitals.

Abstract The fishing industry produces byproducts that accumulate and cause environmental pollution problems; however, could be used as an alternative source of nutrients in ruminants. The objective of the present study was to evaluate the response over ruminal microbiome, apparent digestibility and productivity of Katahdin lambs fed different levels of shrimp shell meal (HCC). Four male lambs with live weight of 22 ± 2.5 kg were assigned in a repeated Latin square design (4 animals x 4 treatments). The animals were assigned for 16 days per period to diets with 0, 5, 10 and 20 g 100 g DM of HCC, the treatments were: HCC0, HCC5, HCC10 and HCC20, respectively. The greatest daily weight gain was found in the HCC5 treatment (P ≤ 0.05). However, the highest dry matter intake was observed in animals with the HCC20 diet (P ≤ 0.05). In the apparent digestibility of the dry matter there was no difference between treatments (P > 0.05), neither in the concentration of total bacteria (P > 0.05), while the concentration of cellulolytic bacteria and chitin-degrading bacteria was higher in the animals from HCC20 treatment (P ≤ 0.05). The results indicate an adaptation of the ruminal microbiome to high doses of HCC, therefore, HCC can be used in diets for sheep without effect on rumen metabolism and microbial, nutrient digestibility and animal performance.

Resumen La industria pesquera genera subproductos que al acumularse causan problemas de contaminación ambiental; sin embargo, podrían ser una fuente de nutrientes para rumiantes. El objetivo de este estudio fue evaluar la respuesta sobre el microbioma ruminal, la digestibilidad aparente y productividad de borregos Katahdin alimentados con diferentes niveles de harina de caparazón de camarón (HCC). Cuatro borregos machos con peso vivo de 22 ± 2.5 kg fueron asignados en un diseño cuadrado latino (4 animales x 4 tratamientos) repetido. Los animales fueron asignados durante 16 días por periodo a dietas con 0, 5, 10 y 20 g 100 g-1 de MS de HCC, los tratamientos fueron: HCC0, HCC5, HCC10 y HCC20, respectivamente. La mayor ganancia diaria de peso se tuvo en los animales del tratamiento HCC5 (P ≤ 0.05). Sin embargo, el mayor consumo de materia seca se observó en los animales con la dieta HCC20 (P ≤ 0.05). En la digestibilidad aparente de la materia seca no hubo diferencia entre tratamientos (P > 0.05), ni en la concentración de bacterias totales (P > 0.05), mientras que la concentración de bacterias celulolíticas y de bacterias degradadoras de quitina, fue mayor en los animales del tratamiento con HCC20 (P ≤ 0.05). Los resultados indican una adaptación del microbioma ruminal a dosis altas de HCC, por tanto, se puede usar HCC en dietas para borregos sin efecto en el metabolismo y microbiana ruminal, la digestibilidad de los nutrientes y en el desempeño de los animales.

Abstract Iodine (I) is an essential element in human nutrition, however, in plants it is considered a beneficial element. The objective of the present work was to evaluate the application of nanochitosan-iodine complexes (NPsCs-I) on the biofortification of I in lettuce, in addition to its effect on growth and yield. Foliar application of NPsCs-I complexes was carried out on lettuce plants where plant height, head diameter, dry biomass and I content were measured. The application of NPsCs-I complexes had a significant effect on the yienld, since with the application of the complex at a dose of 5 mg L-1 of KIO3, it increased by 30.8% compared to the control. The foliar application of NPsCs-I complexes can provide an alternative for biofortification of I and biostimulation of lettuce plants.

Resumen El yodo (I) es un elemento esencial en la nutrición humana, sin embargo, en las plantas se considera un elemento benéfico. El objetivo del presente trabajo fue evaluar la aplicación de complejos de nanoquitosán-yodo (NPsCs-I) sobre la biofortificación del I en la lechuga, además de su efecto en el crecimiento y rendimiento. Se realizó la aplicación foliar de los complejos de NPsCs-I en plantas de lechuga donde se midió la altura de planta, diámetro de la cabeza, biomasa seca y contenido de I. La aplicación de los complejos de NPsCs-I tuvo un efecto significativo en el rendimiento, ya que con la aplicación del complejo en dosis de 5 mg L-1 de KIO3, se incrementó en un 30.8% con respecto al testigo. La aplicación foliar de los complejos de NPsCs-I puede significar una alternativa de biofortificación de I y bioestimulación de plantas de lechuga.

RESUMEN Introducción: el SARS-CoV-2 desde el 2020 generó innumerables desafíos. El decúbito prono se utilizó para mejorar la oxigenación, y la terapia nutricional se adaptó para cubrir los requerimientos y reducir complicaciones. Objetivos: evaluar la tolerancia de la nutrición enteral y su adecuación energética en pacientes ventilados en decúbito prono con infección por SARS-CoV-2, en sala respiratoria del Departamento de Cuidados Intensivos Adultos del Hospital de Clínicas-Facultad de Ciencias Médicas - Universidad Nacional de Asunción, de marzo a julio 2021. Metodología: estudio observacional, descriptivo, retrospectivo, de corte transversal, de casos consecutivos, con información obtenida de fichas de pacientes de terapia intensiva, que recibieron soporte nutricional en posición prona. Se tomaron datos demográficos, clínicos y nutricionales. Se evaluó la tolerancia nutricional durante la posición prona, definiéndola como la presencia de un volumen de residuo gástrico < 500 mL cada 6 h.. La adecuación energética fue determinada teniendo en cuenta el porcentaje cumplido de la prescripción nutricional. Resultados: se reclutaron 41 pacientes. El 60,9 % eran hombres; la mediana de edad fue 55 años (RIC=23). Las principales comorbilidades fueron obesidad (57,3 %) e hipertensión arterial (43,9 %). El 85,4 % presentó buena tolerancia gástrica en posición prono, con residuo gástrico menor a 500 ml. El porcentaje de adecuación energética fue de 84 %. Conclusión: la terapia nutricional enteral en decúbito prono fue bien tolerada por la mayoría de nuestros pacientes, posibilitando alcanzar los requerimientos nutricionales indicados.

ABSTRACT Introduction: SARS-CoV-2 since 2020 has generated countless challenges. Prone position was used to improve oxygenation, and nutritional therapy was adapted to meet requirements and reduce complications. Objectives: evaluate the tolerance of enteral nutrition and its energetic adequacy in ventilated patients in the prone position with SARS-CoV-2 infection, in the respiratory room of the Adult Intensive Care Department of the Hospital de Clínicas - Facultad de Ciencias Médicas - Universidad Nacional de Asunción, from March to July 2021. Methodology: observational, descriptive, retrospective, cross-sectional study of consecutive cases, with information obtained from records of intensive care patients, who received nutritional support in a prone position. Demographic, clinical and nutritional data were taken. Nutritional tolerance was evaluated during the prone position, defining it as the presence of a volume of gastric residue < 500 mL every 6 h. Energy adequacy was determined taking into account the percentage fulfilled of the nutritional prescription. Results: 41 patients were recruited. 60.9 % were men; the median age was 55 years (IQR=23). The main comorbidities were obesity (57.3 %) and high blood pressure (43.9 %). 85.4 % had good gastric tolerance in the prone position, with gastric residue less than 500 ml. The percentage of energy adequacy was 84 %. Conclusion: enteral nutritional therapy in the prone position was well tolerated by the majority of our patients, making it possible to achieve the indicated nutritional requirements.

The South African food system is facing severe challenges as increasing hunger, rising food costs, lack of dietary diversity, child stunting, foodborne illnesses, food waste and an obesity epidemic coupled with malnutrition are observed. In this study, we aimed to establish the application of science and technology advances in the food and beverage industry in South Africa in response to food consumption pattern changes since 1994 and how they could be used to address food security challenges. We found that food consumption shifts have been towards sugar-sweetened beverages, processed and packaged food, animal-source foods and added caloric sweeteners, and away from vegetables. These dietary shifts are concerning as they relate to public health. Most commitments to improve the nutritional status of South Africans have been limited to corporate social investment strategies and should be extended into core business strategies. Furthermore, although the South African food and beverage industry has kept pace with developments in food manufacturing practices, there has been little experimentation with non-commercial novel technologies. The expert survey revealed that indigenous African crops and food waste recovery are the two most promising emerging food sources that could be available to South Africans in the shortest time frame. South Africa has many enabling drivers to become a global leader in food technology advances. However, many barriers need to be overcome for industry, academia and government to collaborate to advance novel food science and technologies to reach commercialisation. SIGNIFICANCE: • Drivers and consequences of food consumption changes in South Africa were modelled and broad food consumption trends between 1994 and 2009/2012 were identified. • For the first time, the Access to Nutrition Index methodology was applied to South African owned food companies to identify strategies to enhance nutrition practices. Companies need to do more to deliver affordable and accessible products. • Drivers and barriers in adopting advanced food science and technology were modelled. A collective ecosystem approach with industry, academia and government mobilisation around critical areas like hunger, malnutrition and poverty could be a way to tackle the failing food system.
