RESUMEN

Resumen: Los cormos de malanga son tallos subterráneos con alto valor nutrimental por su contenido de carbohidratos y proteínas, además de ser altamente digestivos. El almidón que se extrae de ellos puede ser utilizado en la encapsulación de microorganismos probióticos, de gran importancia para la salud. El objetivo de este trabajo fue desarrollar un suplemento alimenticio con características funcionales, usando bacterias ácido lácticas (BAL) (Lactobacilos casei), encapsuladas en almidón de malanga (Xanthosoma sagittifolium). El suplemento se realizó mezclando 150 mL de pulpa de fruta cocida (mango o manzana) con 400 mL de suero de leche (pH de 6.0), a 45 ± 1 °C, hasta conseguir la consistencia deseada (449.9 mPas/s a una temperatura de 25 ºC). Posteriormente, se adicionaron 1 % o 2 % de almidón de malanga (p/v) y 10 mL de cultivo probiótico por cada 100 mL de mezcla. Se deshidrató a 80 ºC y 150 ºC con flujo de aire de 20 mL/min para manzana y 8 mL/min para mango mediante secado por aspersión. El rendimiento fue de 12 %, con una viabilidad de las BAL en el suplemento deshidratado a los 3 meses de almacenamiento superior a 1 x 108 UFC/g. La ausencia de bacterias coliformes, así como de salmonella y shigella, indican que los suplementos son inocuos y aptos para consumo. La composición nutrimental del suplemento de manzana obtenido fue2.23 % de fibra, 5.93 % de grasa, 4.95 % de proteína y un 79 % de hidratos de carbono; el suplemento de mango, el contenido fue 0.59 % de fibra, 7.6 % de grasa, 4.2 % de proteína y 80.20 % de hidratos de carbono. El almidón de malanga permitió la microencapsulación de las BAL y mantener su viabilidad durante el almacenamiento de los suplementos alimenticios desarrollados con base en suero de leche y fruta.

Abstract: Malanga corms are an underground stem with a high nutritional value as it contains carbohydrates and proteins, in addition to being highly digestive; The starch extracted from them can be used in the encapsulation of probiotic microorganisms, which are of great importance for human health. The objective of this work was to develop a food supplement with functional characteristics, added with lactic acid bacteria (Lactobacillus casei) (LAB), using malanga (Xanthosoma sagittifolium) starch. The supplement was obtained by mixing 150 mL of cooked fruit pulp (mango or apple) with 400 mL of sweet whey (pH of 6.0), at a temperature of 45 ± 1 °C until the desired consistency (449.9 mPas/s at a temperature of 25 °C) was achieved. Subsequently, 1 % or 2 % of malanga starch (p/v) and 10 mL of probiotic cultures were added per each 100 mL of mixture. it was then dehydrated at 80 ºC and 150 °C with an air flow of 20 mL/min for apple and 8 mL/min for mango by spray drying. The yield was 12 %, with viability of LAB in the dehydrated supplement at 3 months of storage higher than 1 x 108 CFU/g. The absence of coliform bacteria, as well as Salmonella and Shigella, indicate that the supplements are safe and suitable for consumption. The nutritional composition of the apple supplement was 2.23 % fiber, 5.93 % fat, 4.95 % protein and 79 % carbohydrates; the mango supplement content was 0.59 % fiber, 7.6 % fat, 4.2 % protein and 80.20 % carbohydrates. The malanga starch allowed the LAB microencapsulation and the maintenance of their viability during the storage of sweet whey and fruit-based food supplements.

RESUMEN

INTRODUCTION: Iodine deficiency is linked to thyroid dysfunction, particularly in pregnant women. The objective of this study was to ascertain the iodine levels of women in the second trimester of pregnancy, analysing the influence of iodine ingestion on urinary iodine concentration (UIC) and maternal thyroid function. METHODS: A prospective observational study of pregnant women from Health Area IV of Asturias (northern Spain) recruited before 13 weeks of gestation between May and June 2017. A questionnaire on iodine intake was completed at the first visit, and urine and serum samples were collected at baseline and again during the second trimester. UIC, thyroid stimulating hormone (TSH) and free thyroxine (FT4) obtained in the second trimester of gestation were analysed and related to iodine intake. Thyroid autoimmunity was also analysed in half of the pregnant women at baseline. RESULTS: A total of 241 pregnant women were studied. Of these, 56.7% used iodised salt, 46.7% consumed ≥2 servings of dairy products daily and 88.1% took iodine supplements. Median UIC was 191µg/l (135.3-294µg/l), with 68.1% of the women having UIC ≥150µg/l. Only iodised salt consumption provided protection against iodine deficiency (odds ratio 0.35 [0.20-0.63], p=0.001). In women with no autoimmune thyroid disease (n=88), mean levels of TSH were lower in those that consumed iodised salt than in those that did not (respectively, 2.08±0.89mIU/l vs. 2.56±1.02mIU/l, p=0.025). In women with autoimmune thyroid disease (n=30), mean levels of TSH were higher in those that took iodine supplements than in those that did not (respectively, 2.97±1.25mIU/l vs. 1.16±0.41mIU/l, p=0.002). CONCLUSIONS: The pregnant women studied from Health Area IV in Asturias maintain adequate nutritional iodine status in the second trimester of gestation. In our sample, only the consumption of iodised salt was associated with adequate iodine nutrition, without affecting maternal thyroid function. Most of the women used iodine supplements, which was linked to higher levels of TSH in pregnant women with autoimmune thyroid disease.

RESUMEN

Antecedentes: el beta-hidroxi-beta-metilbutirato es un metabolito natural que se forma a partir de la descomposición de la leucina (aminoácido de cadena ramificada) y cuya popularidad como suplemento ha ido aumentando en los últimos años. Varios estudios se han centrado en abordar sus efectos tanto en el rendimiento deportivo como en personas no entrenadas. Objetivo: el objetivo de este estudio fue determinar los efectos del beta-hidroxi-beta-metilbutirato en la hipertrofia muscular desde tres enfoques de suplementación: adulto joven, adulto mayor y suplementación conjunta. Materiales y métodos: esta revisión se llevó a cabo en bases de datos como Pubmed, Springer Link y Science Direct, con el propósito de resumir e identificar los posibles efectos de esta suplementación desde el año 2012 hasta el año 2020. Resultados: en términos generales, la búsqueda arrojó en total 50 artículos, de los cuales, 31 se desarrollan en la línea de adulto joven, 10 en la línea de adulto mayor y 9 en la línea de suplementación conjunta. La primera línea fue la de mayor evidencia, y en ella se resaltan los principales hallazgos en torno al objetivo de la investigación. Conclusiones: a causa de los pocos estudios publicados en este aspecto específico (hipertrofia), concluir los efectos exactos al suplementar con beta-hidroxi-beta-metilbutirato es controversial, porque hasta la fecha se sigue discutiendo a favor de sus efectos o, por oposición, su no evidencia. La aclaración de los resultados debe ser abordada con prudencia. En los estudios abordados de los efectos, con mayor abundancia se encontró la composición corporal, la fuerza y el daño muscular, seguidos de la preservación de masa, la toxicidad, el estado hormonal y la biogénesis mitocondrial

Background: Beta-hydroxy-beta-methylbutyrate is a natural metabolite formed from the breakdown of leucine (a branched-chain amino acid), and its popularity as a supplement has been increasing in recent years. Several studies have focused on addressing its effects on both athletic performance and untrained individuals. Objective: The aim of this study was to determine the effects of beta-hydroxy-beta-methylbutyrate on muscle hypertrophy from three supplementation approaches: young adults, older adults, and combined supplementation. Materials and Methods: This review was conducted on databases such as PubMed, Springer Link, and Science Direct to summarize and identify the possible effects of this supplementation from 2012 to 2020. Results: Overall, the search yielded a total of 50 articles, of which 31 were developed in the young adult line, 10 in the older adult line, and 9 in the combined supplementation line. The young adult line had the most evidence, with the main findings highlighted around the research objective. Conclusions: Due to the limited number of studies published on this specific aspect (hypertrophy), concluding the exact effects of supplementing beta-hydroxy-beta-methylbutyrate is controversial, as there is still ongoing debate regarding its effects or lack of evidence. Clarification of the results should be approached with caution. Among the effects studied, body composition, strength, and muscle damage were found most abundantly, followed by mass preservation, toxicity, hormonal status, and mitochondrial biogenesis

RESUMEN

Objective: to evaluate the effects of a new glycemia targeted specialized supplement (GTSS) compared to a standard breakfast on postprandial blood glucose (PPG). Methods: patients with type 2 diabetes (T2D) and suboptimal control (A1C between 6.5 and 8.5 %) in monotherapy with metformin were included to this prospective, randomized, crossover trial. The standardized breakfast was isoenergetic compared to the GTSS, differing on macronutrients distribution. Both interventions were used once a day in the morning, each replacing breakfast for 7 consecutive days (14 days of observation). Intermittent scanning continuous glucose monitoring system (isCGM) determined the difference between the interventions regarding the incremental area under the curve (iAUC) of the PPG (3 hours after intervention), as a primary endpoint; secondary endpoints were the difference between the interventions regarding the glycemic peak, postprandial glucose excursion (PPGE), mean blood glucose (MBG) and time in range (TIR). Results: thirty-one T2D patients with ages between 39 and 69 years-old were enrolled. GTSS group had significantly lower iAUC of the PPG compared to standardized breakfast (33.3 [15.0 to 54.0] vs 46.8 [27.3 to 75.1] mg/dL), while also presenting a significantly lower PPG excursion (26.4 ± 17.2 vs 44.8 ± 24.4 mg/dL). There was no difference between the intervention periods regarding MBG, TIR and hypoglycemic events. Conclusion: The new GTSS, as a meal replacement in the breakfast, produced a 25 % reduction in the iAUC of the PPG, as accessed by isCGM, in comparison with an isocaloric-standardized meal. (AU)

Objetivo: evaluar los efectos de un suplemento especializado en el control de la glucosa (GTSS) frente a un desayuno estándar sobre la glucemia posprandial (PPG). Metodología: es un estudio cruzado, prospectivo, aleatorizado en el que se incluyeron a pacientes con diabetes tipo 2 (T2D) con control subóptimo de la glucemia (HbA1c entre 6,5 y 8,5 %) utilizando monoterapia con metformina. El desayuno estandarizado fue isocalórico en comparación con el GTSS y solamente la distribución calórica fue diferente. Ambas intervenciones se utilizaron una vez al día por la mañana, reemplazando cada una el desayuno durante 7 días consecutivos (14 días de observación). Se utilizó el sistema de monitoreo continuo de glucosa (isCGM) para determinar las diferencias entre las intervenciones con respecto al área bajo la curva (iAUC) de glucosa postprandial (PPG) (3 horas después de la intervención) como variable principal o primaria; las variables secundarias fueron la diferencia entre las intervenciones con respecto al pico glicémico, la excursión de glucosa posprandial (PPGE), la glucosa media en sangre (MBG) y el rango de tiempo (TIR). Resultado: se incluyeron treinta y un pacientes con T2D con edades entre 39 y 69 años. El grupo del GTSS tuvo un área bajo la curva (iAUC) significativamente más baja de la PPG en comparación con el grupo del desayuno estandarizado (33,3 [15,0 a 54,0] frente a 46,8 [27,3 a 75,1] mg/dL), mientras que también presentó una PPG significativamente más baja (26,4 + 17,2 vs. 44,8 + 24,4 mg/dL). No hubo diferencia entre los períodos de intervención con respecto a la MBG, el TIR y eventos hipoglucémicos. Conclusión: el nuevo GTSS, como sustituto del desayuno, produjo una reducción de la iAUC de la PPG del 25 %, según el isCGM, en comparación con un desayuno isocalórico normalizado. (AU)

RESUMEN

A cafeína é uma substância presente em diversas bebidas e suplementos, que sua forma mais comum de ingestão é através do café. Devido a ampla procura pela substância e sua larga distribuição mundial, este trabalho apresenta uma revisão de literatura sobre a cafeína e seus efeitos no organismo humano. Ao longo do tempo, a cafeína teve seu consumo aumentado em diversas faixas etárias, além de estar presente em diferentes produtos. A ingestão da cafeína pode estimular a concentração e melhorar o desempenho físico, devido ao seu efeito estimulante do sistema nervoso central. O uso em suplementos está envolvido nos seus efeitos termogênicos, auxiliando no processo de lipólise e melhorando o rendimento nas atividades físicas. O consumo da cafeína é associado ainda com a redução do LDL-colesterol, porém, os efeitos sobre o colesterol plasmático ainda são controversos. Todavia, o uso excessivo da cafeína pode trazer malefícios ao sistema cardiovascular como a diminuição da frequência e pressão cardíaca, dilatação de vasos e redução da temperatura corporal. A sua ingestão quando associada a bebidas alcoólicas pode ocultar a sensação depressiva do álcool, podendo elevar as chances de intoxicação. Na gestação aconselha-se o uso limitado, pois não há estudos conclusivos sobre os efeitos da cafeína para o feto. A relação risco e benefício deve sempre ser avaliada de acordo com cada indivíduo, sendo o aconselhamento e acompanhamento do consumo da cafeína realizado por um profissional de saúde habilitado, como o farmacêutico, para assim se reduzir possíveis prejuízos que a cafeína pode trazer à saúde.

Caffeine is a substance present in several drinks and supplements, which its most common form of intake is through coffee. Due to the broad demand for the substance and its wide distribution worldwide, this work presents a literature review on caffeine and its effects on the human organism. Over time, caffeine has increased its consumption in several age groups, in addition to being present in different products. The intake of caffeine can stimulate concentration and improve physical performance, due to its central nervous system stimulating effect. The use in supplements is involved in its thermogenic effects, assisting in the process of lipolysis and improving the performance in physical activities. The consumption of caffeine is also associated with the reduction of LDL-cholesterol, but the effects on plasma cholesterol are still controversial. However, excessive use of caffeine can cause harm to the cardiovascular system, such as decreased heart rate and pressure, vessel dilation, and reduced body temperature. Ingestion of alcohol in association with alcohol may mask the depressive sensation of alcohol and may increase the chances of intoxication. In pregnancy, limited use is advised, as there are no conclusive studies on the effects of caffeine on the fetus. The risk-benefit ratio should always be evaluated according to each individual, and the advice and follow-up of caffeine consumption is carried out by a qualified health care professional, such as the pharmacist, in order to reduce possible damage that caffeine can bring to health.

Con el tiempo, la cafeína aumentó su consumo en varios grupos de edad, además de estar presente en diferentes productos. La ingesta de cafeína puede estimular la concentración y mejorar el rendimiento físico debido a su efecto estimulante sobre el sistema nervioso central. El uso en suplementos participa en sus efectos termogénicos, ayudando al proceso de lipolisis y mejorando el rendimiento en actividades físicas. El consumo de cafeína también está asociado con la reducción del colesterol LDL, pero los efectos sobre el colesterol plasmático siguen siendo polémicos. Sin embargo, el uso excesivo de cafeína puede dañar el sistema cardiovascular, como una reducción de la frecuencia y la presión cardiaca, la dilatación de los vasos y una reducción de la temperatura corporal. La deglución combinada con alcohol puede enmascarar la sensación deprimida de alcohol y puede aumentar la posibilidad de intoxicación. En el embarazo se aconseja un uso limitado, ya que no hay estudios concluyentes sobre los efectos de la cafeína sobre el feto. La relación riesgo-beneficio debe evaluarse siempre de acuerdo con cada individuo, con el asesoramiento y el control del consumo de cafeína por parte de un profesional sanitario autorizado, como el farmacéutico, a fin de reducir el posible daño que la cafeína puede causar a la salud.

RESUMEN

Introducción: La adecuada nutrición en el embarazo depende no solo de la correcta ingesta de alimentos, sino también de una apropiada administración de vitaminas, minerales y otros nutrientes en forma de suplementos. Objetivo: Describir aspectos relacionados sobre la suplementación con ácido fólico, hierro, yodo, calcio, vitamina B12 y omega-3, durante el embarazo. Método: Se realizó una revisión sistemática entre mayo de 2022 y marzo de 2023 sobre la suplementación con algunas vitaminas y minerales durante el embarazo. Se revisaron bases de datos electrónicas de literatura científica biomédica como: UpToDate, Science Direct, SciELO y PUBMED, LILACS. Se realizó la búsqueda de artículos desde el 2016 hasta 2022. Los términos de búsqueda en las bases de datos fueron: suplementos "Vitaminas", "Micronutrientes", "Minerales", y "Embarazo", en inglés y en español. Resultados: Los requerimientos de vitaminas, minerales y diferentes nutrientes aumentan en el embarazo. Una apropiada alimentación y el consumo de micronutrientes en forma de suplementos son el soporte básico para un adecuado desarrollo de la madre y del feto; por otra parte, una nutrición adecuada reduce el riesgo de malformaciones congénitas, complicaciones obstétricas, fetales y perinatales. No todas las embarazadas necesitan la misma cantidad de suplementos, por lo que es necesario identificar aquellas con mayor riesgo de presentar alguna deficiencia. Conclusiones: La suplementación de vitaminas, minerales y otros micronutrientes durante el embarazo es muy importante para disminuir el riesgo de complicaciones obstétricas y anomalías fetales y perinatales.

Method: A systematic review was conducted between May 2022 and March 2023, concerning supplementation intake of vitamins and minerals in pregnancy. Electronic databases of biomedical scientific literature were reviewed such as: UpToDate, Science Direct, SciELO and PUBMED, LILACS. Searching was on articles published from 2016 to 2022. The key terms for searching in databases were as follow: supplements "Vitamins", "Micronutrients", "Minerals", and "Pregnancy", in English and Spanish. Results: A vitamin, minerals and different nutrients intake requirements has increased in pregnancy. An appropriate diet and the consumption of micronutrients in the form of supplements are the basic support for an adequate health status of the mother and the development the fetus; on the other hand, an adequate nutrition reduces the risk of congenital malformations, obstetric, fetal and perinatal complications. Not all pregnant women need the same amount of supplements, so it is necessary to identify those with a highest risk of presenting deficiency. Conclusions: Supplementation of vitamins, minerals and other micronutrients in pregnancy is very important to reduce the risk of obstetric complications and fetal or perinatal anomalies.

Introdução: a nutrição adequada durante a gravidez depende não só da ingestão correta de alimentos, mas também da administração adequada de vitaminas, minerais e outros nutrientes na forma de suplementos. Objetivo: descrever aspectos relacionados à suplementação com ácido fólico, ferro, iodo, cálcio, vitamina B12 e ômega 3, durante a gestação. Método: foi realizada uma revisão sistemática entre maio de 2022 e março de 2023 sobre a suplementação com algumas vitaminas e minerais durante a gravidez. Bases de dados eletrônicas de literatura científica biomédica como: UpToDate, Science Direct, SciELO e PUBMED, LILACS foram revisadas. A busca dos artigos foi realizada no período de 2016 a 2022. Os termos de busca nas bases de dados foram: suplementos "Vitamins", "Micronutrients", "Minerals" e "Pregnancy", nos idiomas inglês e espanhol. Resultados: as necessidades de vitaminas, minerais e diferentes nutrientes aumentam na gravidez. Uma dieta adequada e o consumo de micronutrientes na forma de suplementos são o suporte básico para um desenvolvimento adequado da mãe e do feto; por outro lado, uma nutrição adequada reduz o risco de malformações congênitas, complicações obstétricas, fetais e perinatais. Nem todas as gestantes precisam da mesma quantidade de suplementos, por isso é necessário identificar aquelas com maior risco de apresentar deficiência. Conclusões: a suplementação de vitaminas, minerais e outros micronutrientes durante a gravidez é muito importante para reduzir o risco de complicações obstétricas e anomalias fetais e perinatais.

RESUMEN

Abstract Objectives: to evaluate the use of iron supplementation and associated factors in children aged six to 59 months attended at the Family Health Strategy units in a city in Minas Gerais (MG). Methods: a cross-sectional, analytical-exploratory study, carried out with 252 children aged six to 59 months, attended at ten units, between 2014 and 2016. A structured questionnaire was used to collect data on socioeconomic conditions, maternal health, child's health and the knowledge of those responsible regarding anemia and iron supplementation, in addition to analysis of the child's medical records /booklet to collect test results. Descriptive statistics, bivariate association analysis and logistic regression for multivariate analysis were performed. Results: only 22.6% of the children aged between six and 24 months were receiving iron supplement at the time of the interview. Considering children aged six to 59 months, 13.1% were supplemented and breastfeeding time (p=0.006) and the participation in childcare (p=0.042), were positively associated with the use of supplementation. Conclusion: most children aged six to 24 months were not receiving supplementation as recommended by the Ministry of Health, demonstrating the need to implement prevention programs, such as the National Iron Supplementation Program and training of professionals on the importance of health education in preventing childhood anemia.

RESUMEN

Abstract Objective The aim of this study was to systematically review literature on the use of iron supplements (not including iron derived from diet), increased levels of hemoglobin and/or ferritin, and the risk of developing gestational diabetes mellitus (GDM). Data source The following databases were searched, from the study's inception to April 2021: PUBMED, Cochrane, Web of Science, Scopus, Embase, Cinahl and Lilacs. Selection of studies A total of 6,956 titles and abstracts were reviewed, 9 of which met the final inclusion criteria, with 7,560 women in total. Data collection Data extraction was performed by two independent reviewers and disagreements were resolved by a third researcher. Data synthesis Methodological quality in controlled trials were assessed according to the Cochrane Collaboration tools (ROB-2 and ROBINS-1) and for the observational studies, the National Institutes of Health's (NIH) quality assessment tool was used. Among the 5 observational studies, women with a higher hemoglobin or ferritin level were more likely to develop GDM when compared with those with lower levels of these parameters. Among the 3 randomized clinical trials, none found a significant difference in the incidence of GDM among women in the intervention and control groups. However, we identified many risks of bias and great methodological differences among them. Conclusion Based on the studies included in this review, and due to the important methodological problems pointed out, more studies of good methodological quality are needed to better establish the association between iron supplementation and GDM.

Resumo Objetivo O objetivo deste estudo foi revisar sistematicamente a literatura sobre o uso de suplementos de ferro (não incluindo o ferro derivado da dieta), aumento dos níveis de hemoglobina e/ou ferritina e o risco de desenvolver diabetes mellitus gestacional (DMG). Fontes dos dados as bases de dados PUBMED, Cochrane, Web of Science, Scopus, Embase, Cinahl e Lilacs foram pesquisadas até abril de 2021. Seleção dos estudos Foram revisados 6.956 títulos e resumos, dos quais 9 preencheram os critérios finais de inclusão, totalizando 7.560 mulheres. Coleta de dados A extração de dados foi realizada por dois revisores independentes e as divergências foram resolvidas por um terceiro revisor. Síntese dos dados A qualidade metodológica dos ensaios controlados foi avaliada de acordo com as ferramentas da Colaboração Cochrane (ROB-2 e ROBINS-1) e para os estudos observacionais, foi utilizada a ferramenta de avaliação de qualidade do National Institutes of Health (NIH). Entre os 5 estudos observacionais, as mulheres com maiores níveis de hemoglobina ou ferritina apresentaram maior probabilidade de desenvolver DMG quando comparadas àquelas com níveis mais baixos nesses parâmetros. Entre os 3 ensaios clínicos randomizados, nenhum deles encontrou diferença significativa na incidência de DMG entre as mulheres dos grupos de intervenção e controle. No entanto, identificamos muitos riscos de viés e enormes diferenças metodológicas entre eles. Conclusão Com base nos estudos incluídos nesta revisão e devido aos importantes problemas metodológicos apontados, são necessários mais estudos de boa qualidade metodológica para melhor estabelecer a associação entre suplementação de ferro e DMG.

RESUMEN

Objectives: the study describes the evolution over the years of the use of artificial nutrition, in particular after the introduction of a dedicated Clinical Nutrition and Dietetic Service. Methods: a single-center, retrospective observational study performed with data collected from 2014 to 2019 at the Regional Hospital of Locarno, Switzerland. Results: from 2014 to 2019, there has been an increase in the number of patients identified as being at risk of malnutrition. We observed a reduction in the use of parenteral nutrition in all services, especially after the introduction of the dedicated Clinical Nutrition and Dietetic Service. There would seem to be a switch from enteral to oral nutrition with increased use of oral nutritional supplements. Conclusions: the introduction of a dedicated Clinical Nutrition and Dietetic Service in the care of patients with nutritional issues would seem to reduce the use of artificial invasive nutrition, despite an increase in the number of patients identified as being at risk of malnutrition.

RESUMEN

Objetivo: el objetivo de nuestro estudio en vida real fue evaluar en pacientes ingresados desnutridos la adherencia y las preferencias de sabor de un suplemento oral Nutricional (SON) hipercalórico e hiperproteico. Métodos: se incluyeron en este estudio en vida real un total de 34 pacientes ingresados con pérdida de peso reciente. Se administró un sabor (café, vainilla o fresa) cada día de forma aleatoria a cada paciente durante tres días consecutivos. En los primeros tres días se pidió a los pacientes que completaran dos cuestionarios destinados a reflejar la tolerancia y aceptación del SON (Renutryl®). La adherencia del SON fue evaluada durante el ingreso hospitalario. Resultados: el sabor dulce fue más elevado para el sabor fresa (4,54 ± 0,2 puntos) que para el sabor vainilla (3,13 ± 0,1 puntos; p < 0,03) y el sabor café (3,03 ± 0,1 puntos; p < 0,02). Al analizar a los pacientes que tomaron suplementos después de elegir el sabor, los pacientes que eligieron café tomaron un total de 13,3 ± 1,1 envases de promedio durante la hospitalización (0,91 ± 0,2 por día), los pacientes que eligieron fresa tomaron 13,4 ± 1,3 envases (0,92 ± 0,1 por día) y, finalmente, los pacientes que eligieron envases de vainilla tomaron 8,3 ± 0,9 envases durante el ingreso (0,61 ± 0,1 por día), con diferencias significativas a favor de los sabores de fresa y café frente al sabor de vainilla. Por otra parte, el SON elegido mayoritariamente por los pacientes al alta hospitalaria fue el pack multisabor (n = 20; 50 %).Conclusiones: las preferencias de sabor de los SON de tres sabores son similares, aunque la adherencia fue más elevada durante el ingreso con respecto a los SON con sabor a café y fresa. La dulzura puede haber influido en este hallazgo, sobre todo con el sabor fresa, con una buena tolerancia de los 3 sabores (AU)

Aim: the objective of our real-life study was to evaluate adherence and taste preferences of a hypercaloric and hyperprotein oral nutritional supplement (ONS) in malnourished hospitalized patients. Methods: a total of 34 in patients with recent weight loss were included in this study. One flavor (coffe, vanilla or strawberry) was administered each day in a random way to each patient during three consecutive days. In the first three days, patients were asked to fulfill two questionnaires intended to reflect ONS (Renutryl®) tolerance and acceptance. Adherence to the ONS was measured during hospital stay. Results: the sweet flavor was higher for strawberry (4.54 ± 0.2 points) than for the vanilla flavor (3.13 ± 0.1 points; p < 0.03) and coffee flavor (3.03 ± 0.1 points; p <0.02). When analyzing the total number of patients who took supplements after choosing the flavor, the patients who chose coffee took a total of 13.3 ± 1.1 packages on average during hospitalization (0.91 ± 0.2 per day), the patients who chose strawberry took 13.4 ± 1.3 packages (0.92 ± 0.1 per day), and finally the patients who chose vanilla packages took 8.3 ± 0, 9 packages during admission (0.61 ± 0.1 per day), with significant differences in favor of the strawberry and coffee flavors versus vanilla. The ONS chosen mostly by the patients at hospital discharge was the multiflavor pack (n = 20; 50 %). Conclusions: taste preferences for the three flavored ONSs are similar, although adherence was higher during admission to the coffee- and strawberry-flavored ONS. Sweetness may have influenced this finding, especially with the strawberry flavor, with a good tolerance of all three flavors (AU)

RESUMEN

Resumen Se pretendió desarrollar una fórmula artesanal, a base de lactosuero, como complemento alimenticio para niños preescolares. Se realizó una investigación descriptiva ejecutada en tres fases: 1. Ensayos preliminares para la determinación del esquema tecnológico; 2. Evaluación fisicoquímica para la caracterización del producto y determinación de macronutrientes y 3. Evaluación sensorial donde se midió el nivel de agrado del producto final. Los datos obtenidos de los análisis se tabularon en cuatro repeticiones y se analizaron a través de estadísticas descriptivas de tendencia central y en frecuencias expresadas en tablas y gráficos mediante el programa estadístico SPSS versión 20.0. Se obtuvo que en el análisis proximal del requesón deshidratado, éste aportó por cada 100 gramos de producto: 480,28 kcal, 46,5% de proteínas, 22,36% de grasas y 23,26% de hidratos de carbono. La formulación final de la bebida constó de 2,9 g de requesón deshidratado, 3,6 g de arroz previamente cocido y 1,8 g de azúcar diluidos por cada onza preparada. Se determinó que es una fórmula hipocalórica-hiperproteica e isoosmolar, con una viscosidad de 275cP, un pH de 5,1 y con 0,291% de ácido láctico. La fórmula artesanal a base de lactosuero fue de agrado para 41 niños que participaron en el análisis sensorial. Se recomienda su uso en niños que se encuentren en condición de vulnerabilidad nutricional.

Abstract The main objective of this research was to develop an artisan formula based on whey as food supplement directed to preschool children. It was a descriptive study carried out in three phases: 1. Preliminary tests, for the determination of the technological scheme; 2. Physical-chemical evaluation, for the characterisation of the product and determination of nutrients and, 3. Sensory evaluation: the level of satisfaction of the final product measured. The data obtained from the analysis were tabulated in four repetitions and analysed through descriptive statistics of central tendency and in frequencies expressed in tables and graphs using the statistical program SPSS version 20.0. As a result, for each 100 grams of dehydrated cottage cheese this malnuprovides: 480.28 kcal, 46.5% protein; 22.36% fat and 23.26% carbohydrates. The final formulation of the drink consisted of 2.9 g of dehydrated cottage cheese, 3.6 g of previously cooked rice and 1.8 g of diluted sugar for each prepared ounce. It was determined as a hypocaloric-hyperproteic and isomolar formula, with a viscosity of 275cP, a pH of 5.1 and with 0.291% lactic acid. The artisan formula based on whey was liked by 41 children who participated in the sensory analysis. As a conclusion, it can be recommended as food supplement in children with nutritional vulnerability conditions.

RESUMEN

Os suplementos à base de vitamina C são amplamente consumidos pela população, evidenciando a importância da fiscalização desses produtos. Em julho de 2018, a ANVISA (Agência Nacional de Vigilância Sanitária) publicou as novas regulamentações sobre suplementos alimentares, estabelecendo-se o prazo de 60 meses para as empresas se adequarem a essas normas. O presente trabalho teve como objetivo determinar os teores de vitamina C, comparar os valores analisados com os declarados na informação nutricional e avaliar os dizeres de rotulagem em produtos à base dessa vitamina. Os teores de vitamina C foram determinados por titulação potencio métrica e as análises de rotulagem foram realizadas com base nas legislações da ANVISA em doze amostras de suplementos colhidos pelas Vigilâncias Sanitárias do Estado de São Paulo. Os teores de vitamina C avaliados estavam de acordo com os declarados na informação nutricional do rótulo, com exceção de uma amostra que apresentou teor abaixo do valor declarado. Em relação aos dizeres de rotulagem, sete amostras (58%) apresentaram um ou mais itens em desacordo com a legislação, mostrando a necessidade de monitoramento constante desse tipo de produto. O trabalho representa um estudo preliminar de avaliação dos suplementos no período de adequação às novas regulamentações (AU).

Vitamin C-based supplements are widely consumed by the population, highlighting the importance of monitoring these products. In July 2018, the ANVISA (National Health Surveillance Agency) published new regulations for dietary supplements,setting a 60 months deadline for companies to comply with these standards.The objective of the present work was to evaluate the contents of vitamin C, and compare the analyzed/real values with those reported on the nutrition facts label, and to evaluate the labeling of vitamin supplements. Vitamin C contents were determined by potentiometric titration, and labeling analysis were performed based on ANVISA legislation in twelve samples of supplements collected by the Sanitary Surveillance of the State of São Paulo.The contents of vitamin C were in accordance with those declared in the nutritional information on the label, with the exception of one sample that presented content below the declared value. Regarding the labeling analysis, seven samples (58%) presented one or more items in disagreement with the legislation, showing the need for constant monitoring of this type of product.The work represents a preliminary study to evaluate the supplements in the adequacy period of new regulations (AU).

RESUMEN

The cause of recurrent aphthous stomatitis remains unknown, however, different causal factors have been found that could trigger this disease, among them, nutritional deficiencies of vitamins and minerals. In this systematic review (PROSPERO registry #CRD42021259412), we show that dietary supplements decrease the number of recurrent aphthous stomatitis episodes. The long-term efficacy of these supplements corroborates the role of these deficiencies in some patients, indicating that ulcer episodes could be prevented.

La causa de la estomatitis aftosa recurrente sigue siendo desconocida, sin embargo, se han encontrado diferentes factores causales que podrían gatillar esta enfermedad, entre ellos, las deficiencias nutricionales de vitaminas y minerales. En esta revisión sistemática (registro PROSPERO #CRD42021259412), mostramos que los suplementos dietéticos disminuyen el número de episodios de estomatitis aftosa recurrente. La eficacia de estos suplementos a largo plazo corrobora el papel de estas deficiencias en algunos pacientes, lo que indica que los episodios de úlceras podrían prevenirse.
