RESUMO
Objetivo: investigar a percepção do peso corporal e as dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos. Metodologia: estudo observacional transversal, com adultos e idosos com deficiência visual em Pelotas/RS, realizado no período de abril a maio de 2023. Foi utilizado um questionário composto de 42 itens. Os dados coletados foram analisados por análise descritiva e analítica, e apresentados como média ± desvio padrão ou percentual. Resultados: a amostra contou com 20 pessoas, predominantemente do sexo feminino e idosas. Em relação ao consumo alimentar, 50% dos participantes consomem feijão, 75% frutas e hortaliças, 50% bebidas adoçadas, biscoitos recheados e doces. Referente à percepção do peso corporal, percebeu-se que a maior parte do grupo sente que está acima do peso adequado e se sentem "insatisfeitos(as)". Sobre as dificuldades encontradas, 85% dos participantes relataram dificuldade extrema para identificar a validade dos alimentos, 70% para comprar alimentos frescos e perecíveis e 40% para usar a faca para cortar e descascar os alimentos. Conclusão: verificou-se que a maior parte do grupo sente que está acima do peso adequado e estão "insatisfeitos(as)" em relação ao peso corporal. Além disso, dependem de outra pessoa para escolher os alimentos a serem comprados, saber o prazo de validade, preparar alimentos que precisam ser porcionados, servir refeições no prato, cortar carnes, descascar vegetais e frutas, utilizar faca, entre outros. Esta dependência pode influenciar diretamente no seu consumo alimentar quando essas pessoas se encontram sozinhas, optando por consumir alimentos industrializados de fácil preparo ou prontos.
Objective: to investigate the perception of body weight and the difficulties encountered by people with visual impairments in acquiring, preparing and consuming food. Methodology: cross-sectional observational study, with adults and elderly people with visual impairment in Pelotas/RS, carried out from April to May 2023. A questionnaire composed of 42 items was used. The collected data were analyzed using descriptive and analytical analysis, and presented as mean ± standard deviation or percentage. Results: the sample included 20 people, predominantly female and elderly. Regarding food consumption, 50% of participants consume beans, 75% fruits and vegetables, 50% sweetened drinks, stuffed cookies and sweets. Regarding the perception of body weight, it was noticed that the majority of the group feels that they are overweight and feel "dissatisfied". Regarding the difficulties encountered, 85% of participants reported extreme difficulty in identifying the expiration date of food, 70% in purchasing fresh and perishable foods and 40% in using a knife to cut and peel food. Conclusion: it was found that the majority of the group feels that they are overweight and are "dissatisfied" with their body weight. Furthermore, they depend on someone else to choose the food to be purchased, know the expiration date, prepare food that needs to be portioned, serve meals on the plate, cut meat, peel vegetables and fruits, use a knife, among others. This dependence can directly influence their food consumption when these people are alone, choosing to consume easily prepared or ready-made processed foods.

Background: Bevacizumab together with 5-fluorouracil and oxaliplatin inhibit microvascular growth of tumor blood vessels and tumor proliferation. Few reports state the effect of these therapeutic schemes on salivary glands. Materials and Methods: Food consumption, body weight and salivary amylase activity were assessed in the submandibular gland of rats. Adult male Wistar rats, of three months old with 350/400 grams body weight, under 12-hour light/dark cycles respectively, were divided into the following experimental groups: G1) Control group, G2) 5-Fluorouracil and leucovorin calcium treated group, G3) Bevacizumab treated group, G4) Oxaliplatin treated group, G5) Bevacizumab, oxaliplatin, 5-fluorouracil and leucovorin calcium treated group and G6) Drug-free paired feeding treated group. Assessment of treatment effect was performed by one-way ANOVA. A value of p<0.05 was set for statistical significance. Results: Salivary amylase activity in gland homogenate was G1: 137.9 ± 4.64, G2: 60.95±4.64, G3: 120.93 ± 4.96, G4: 26.17 ±4.64, G5: 10.77 ±4.64 and G6: 82.87 ±4.64 U/mg protein (mean ± S.D.) Amylase activity in the G1 group was higher relative to the other experimental groups p<0.0001. Conclusions: The drugs 5-fluorouracil and oxaliplatin altered salivary amylase activity by serous granules of the submandibular gland interpreted as a mechanism of impaired acinar function. Bevacizumab administered in isolation did not alter salivary amylase activity compared to the control group. While the lower intake of the matched feeding group affected salivary amylase activity compared to the control group, the effect was significantly greater in animals treated with the oncology drugs used in the present animal model.
Antecedentes: Bevacizumab, junto con 5-fluorouracilo y oxaliplatino, inhiben el crecimiento microvascular de los vasos sanguíneos tumorales y la proliferación tumoral. Pocos reportes establecen el efecto de estos esquemas terapéuticos sobre las glándulas salivales. Materiales y Métodos: Se evaluaron el consumo de alimentos, el peso corporal y la actividad de amilasa salival en la glándula submandibular de ratas Wistar macho adultas, de tres meses de edad con 350/400 gramos de peso corporal, bajo ciclos de luz/oscuridad de 12 horas respectivamente, se dividieron en los siguientes grupos experimentales: G1) Grupo control, G2) Grupo tratado con 5-Fluorouracilo y Leucovorina cálcica. , G3) Grupo tratado con bevacizumab, G4) Grupo tratado con oxaliplatino, G5) Grupo tratado con bevacizumab, oxaliplatino, 5-fluorouracilo y leucovorina cálcica y G6) Grupo tratado con alimentación emparejada sin fármacos. La evaluación del efecto del tratamiento se realizó mediante ANOVA unidireccional. Se estableció un valor de p<0,05 para significación estadística. Resultado: La actividad de amilasa salival en homogeneizado de glándula fue G1: 137,9 ± 4,64, G2: 60,95 ± 4,64, G3: 120,93 ± 4,96, G4: 26,17 ± 4,64, G5: 10,77 ± 4,64 y G6: 82,87 ± 4,64 U/mg de proteína (media ± S.E.). La actividad de amilasa en el grupo G1 fue mayor en relación con los otros grupos experimentales p<0,0001. Conclusión: Los fármacos 5-fluorouracilo y oxaliplatino alteraron la actividad de la amilasa salival mediante gránulos serosos de la glándula submandibular interpretados como un mecanismo de deterioro de la función acinar. Bevacizumab administrado de forma aislada no alteró la actividad de la amilasa salival en comparación con el grupo de control. Mientras que la menor ingesta del grupo de alimentación combinada afectó la actividad de la amilasa salival en comparación con el grupo de control, el efecto fue significativamente mayor en los animales tratados con los medicamentos oncológicos utilizados en el grupo. modelo animal actual.

Abstract Objectives To review and discuss the role of an elimination diet in food-allergic children, emphasizing nutritional aspects for a better practical approach. Sources Non-systematic review of the literature. Findings Under an elimination diet, food-allergic patients may suffer from growth impairment or obesity and compromised quality of life. Disease phenotype, age, type, number of foods excluded, comorbidities, eating difficulties, economic status, and food availability must be considered for an appropriate diet prescription. Diet quality encompasses diversity and degree of food processing, which may alter immune regulation. Conclusions A friendly food elimination diet prescription depends on a multidisciplinary approach beyond macro and micronutrients.
RESUMO
Abstract Objectives To provide a narrative review of the main eating disorders (ED), specifically focusing on children and adolescents. This review also aims to help the pediatrician identify, diagnose, and refer children and adolescents affected by this medical condition and inform them about the multidisciplinary treatment applied to these disorders. Data source The research was conducted in the Scientific Electronic Library Online (SciELO), Medical Literature Analysis and Retrieval System Online (Medline) databases via PubMed and Embase. Consolidated Guidelines and Guidebooks in the area were also included in the review to support the discussion of ED treatment in childhood and adolescence. Data synthesis ED are psychiatric condition that usually begins in adolescence or young adulthood but can occur at any time of life, including in childhood, which has been increasingly frequent. Pediatricians are the first professionals to deal with the problem and, therefore, must be well trained in identifying and managing these disorders, which can be severe, and determine physical complications and quality of life of patients and their families. Conclusion ED has shown an increase in prevalence, as well as a reduction in the age of diagnosed patients, requiring adequate detection and referral by pediatricians. The treatment requires a specialized multidisciplinary team and is generally long-lasting for adequate recovery of affected individuals.
RESUMO
ABSTRACT BACKGROUND: Some maternal characteristics are related to alcohol intake during pregnancy, which irreversibly compromises the maternal-fetal binomial integrity. OBJECTIVES: To identify the frequency, impact, and factors associated with alcohol consumption during pregnancy. DESIGN AND SETTING: A cross-sectional study was performed at the Hospital Materno Infantil Presidente Vargas (HMIPV) in Porto Alegre/RS between March and December 2016. METHODS: A structured questionnaire was administered along with a medical records review. They refer to the maternal sociodemographic and gestational status, alcohol consumption patterns, and characteristics of the fetus/newborn. In the statistical analysis, P values < 0.05 were considered significant. RESULTS: The frequency of alcohol intake was 37.3%; this was characterized by the consumption of fermented beverages (89.3%), especially during the first trimester (79.6%). Risky consumption (high and/or early) occurred for 30.2% of participants. Risk factors associated with maternal alcohol consumption during pregnancy were tobacco use (P < 0.001) and abortion attempt (P = 0.023). Living with a partner (P = 0.002) and planning pregnancy (P = 0.009) were protective factors. Risky consumption was related to all of the aforementioned variables as well as threatened abortion (P = 0.023). CONCLUSIONS: Alcohol intake during pregnancy is common and affects nearly one-third of pregnant women. Knowledge of the population at risk and protective factors is essential for the development of campaigns that seek to reduce consumption and, therefore, its consequences for the mother and fetus.
RESUMO
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.
RESUMO
Introducción. Los niños con trastorno del espectro autista (TEA) presentan dificultades de adaptación a situaciones estresantes, como la pandemia por COVID-19. Objetivo. Evaluar el impacto del primer año de pandemia en las dificultades alimentarias de niños con TEA. Población y métodos. Se invitó a participar a cuidadores de niños con TEA no sindromático (edad: 2-18 años) de una unidad de neurodesarrollo. Los participantes respondieron en línea un cuestionario y la escala de evaluación de problemas de conducta alimentaria (BPFAS por su sigla en inglés) antes y durante el primer año de pandemia. Se calculó un puntaje de prioridad (producto entre promedio de frecuencia y problema) para cada ítem del BPFAS. Resultados. El 56,6 % (86/152) de los cuidadores contestó la encuesta (madre 74,4 %), mediana de edad 6,3 años (p25-p75: 4,7-8,2); el 80,2 % de los niños eran de sexo masculino; el 58,1 % mantuvo terapia durante la pandemia y el 61,6 % presentaba problemas de comportamiento previo a esta. Durante el primer año de pandemia, los niños presentaron mayor intensidad en dificultades conductuales (34,9 %) y de alimentación (61,6 %); sin embargo, el 31,4 % refirió mejoría en la alimentación. No existieron diferencias significativas entre puntajes BPFAS antes y durante la pandemia. Los ítems con mayor puntaje de prioridad fueron "se levanta de la mesa durante la hora de comer", "no probar alimentos nuevos", "no come verduras", "no come frutas". Conclusiones. Hubo alta frecuencia de dificultades en las conductas alimentarias durante el primer año de pandemia. No se presentaron diferencias en las características de estas conductas antes y durante la pandemia.
Introduction. Children with autism spectrum disorder (ASD) have difficulties adapting to stressful situations, such as the COVID-19 pandemic. Objective. To assess the impact of the first year of the pandemic on feeding difficulties in children with ASD. Population and methods. The caregivers of children and adolescents with non-syndromic ASD (age: 218 years) from a neurodevelopment unit were invited to participate. Participants completed a questionnaire and the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) online before and during the first year of the pandemic. A priority score (product between the average frequency and the problem) for each BPFAS item was estimated. Results. Among the caregivers, 56.6% (86/152) completed the survey (mother: 74.4%); children's median age was 6.3 years (p25p75: 4.78.2); 80.2% of children were males; 58.1% continued with their therapy during the pandemic; and 61.6% had behavioral problems before the pandemic. During the first year of the pandemic, children had greater behavioral problems (34.9%) and feeding difficulties (61.6%); however, 31.4% of caregivers referred improvements in feeding. There were no significant differences in the BPFAS scores before and during the pandemic. The following items obtained the highest priority scores: gets up from table during meal, does not try new food, does not eat vegetables, does not eat fruits. Conclusions. A high frequency of feeding difficulties was noted during the first year of the pandemic. No differences were observed in feeding characteristics before and during the pandemic.

Introducción. La medición del consumo de alimentos es un importante indicador del estado nutricional de las personas; sin embargo, el proceso no es fácil y puede tener un nivel de error inaceptable. La incorporación de nuevas tecnologías pueden facilitar el proceso y minimizar el error. Objetivo. Desarrollar un programa informático en la web para nutricionistas que permita el ingreso de datos de consumo de alimentos con un recordatorio de 24 horas o de los 7 días anteriores, el análisis de la ingesta de energía y nutrientes y su comparación con las ingestas recomendadas; con el fin de minimizar el error en la recopilación y análisis de los datos. Materiales y métodos. Primero, se determinaron las características importantes que debe tener el programa, el cual fue elaborado posteriormente con los lenguajes de programación de Python y Javascript y con un patrón de diseño modelo-vista-controlador. Simultáneamente se crearon tres bases de datos, uno con el valor nutritivo de los alimentos, otro con datos de tamaños de porción de los mismos y otro con las recomendaciones nutricionales. Una vez elaborado, el programa fue sometido a una serie de pruebas para evaluar tanto su facilidad de uso como la exactitud de los cálculos. Resultados. Se describen las 9 etapas del programa y se justifica su diseño con evidencias de la literatura científica. Conclusiones. Se desarrolló el programa en la web, 'Dietnóstico', que permite la recolección y análisis de datos de consumo de alimentos. Una vez validado, el programa estará disponible para nutricionistas a usar en la atención nutricional y la investigación(AU)
Introduction. Assessment of food consumption is an important indicator of a person's nutritional status; however, it is not a simple process and can involve an unacceptable level of error. The application of new technologies in this process can lead to improvements and the minimization of error. Objective. To develop a computer program in the web, for nutritionists that allows the input of food consumption data using a 24- hour recall or a recall of food consumption during the 7 previous days, the analysis of energy and nutrient intake and its comparison with recommended intakes with the aim of minimizing the error involved in the collection and analysis of food consumption data. Materials and methods. The first stage was to define important characteristics to include in the programme which was developed using the programming languages of Python and Javascript and using a model-view-controller design pattern. At the same time, three databases were created: one with the nutritional value of foods, another with portion sizes of the foods and a third with the nutritional recommendations. Once created, several trials were conducted on the programme to test the operations from a user point of view, and the accuracy of the calculations. Results. The 9 stages of the software are described and its design is justified with evidence from the scientific literature. Conclusions. The program 'Dietnóstico' for use in the web, allows the collection and analysis of food consumption data. Once validated, it will be available for nutritionists involved in nutrition counselling and research(AU)

The COVID-19 pandemic and government measures have challenged family functioning (FF) and eating behaviors. In non-pandemic scenarios, FF has shown a protective role in diet quality. This study aimed to explore the role of FF in family members' food consumption during the first wave of the COVID-19 pandemic in Chile. We conducted a cross-sectional, non-probabilistic study. Chilean adults (n= 821) answered an online survey based on the Family Adaptability and Cohesion Evaluation Scales (FACES) IV and a scale of food intake perceptions (non-processed and processed food). The survey also included an open space for comments (n= 147). Most participants had a medium or high FF category. Participants with higher FF had a lower risk of decreasing the consumption of non-processed foods (RR= 0.58 for fruits and RR= 0.45 for legumes) and lower risk of increasing processed foods (RR= 0.37 for sugar-sweetened beverages, RR= 0.46 for snacks, and RR= 0.64 for chocolates) when compared to lower FF participants and controlling for per-capita income. Participants commented on changes in FF: some had more conflicts and others were happy to be together during the pandemic. Most participants indicated that they maintained or increased non-processed and processed food consumption compared to the pre-pandemic period. They perceived having the opportunity of eating healthier during the pandemic. However, the stress they suffered produced them to eat unhealthily. Therefore, FF had a protective role in diet quality during the pandemic. Policymakers should consider FF when promoting healthy diets, especially in health crises.
La pandemia por COVID-19 y las medidas gubernamentales han desafiado el funcionamiento familiar (FF) y los hábitos alimentarios. En escenarios no pandémicos, el FF ha demostrado un papel protector en la calidad de la dieta. Este estudio tuvo como objetivo explorar el papel del FF en el consumo de alimentos de los miembros de la familia durante la primera ola de la pandemia de COVID-19 en Chile. Realizamos un estudio transversal, no probabilístico. Adultos chilenos (n= 821) respondieron una encuesta online basada en la Escala de Evaluación de Cohesión y Adaptabilidad Familiar (FACES) IV y una escala de percepción de consumo de alimentos (alimentos no procesados y procesados). La encuesta también incluyó un espacio abierto para comentarios (n= 147). La mayoría de los participantes tenían una categoría de FF medio o FF alto. Los participantes con mayor FF tenían un menor riesgo de disminuir el consumo de alimentos no procesados (RR= 0,58 para frutas y RR= 0,45 para legumbres) y menor riesgo de aumentar los alimentos procesados (RR= 0,37 para bebidas azucaradas, RR= 0,46 para snacks, y RR= 0,64 para chocolates) en comparación con los participantes de FF más bajos y controlando por ingreso per cápita. Los participantes comentaron cambios en sus FF y teniendo más conflictos, aunque algunos estaban felices de estar juntos durante la pandemia. La mayoría de los participantes indicaron que mantuvieron o aumentaron los alimentos procesados y no procesados en comparación con el período pre-pandemia. Ellos percibieron tener la oportunidad de comer más sano. Sin embargo, el estrés que sufrían les producía comer menos saludable. La FF tuvo un papel protector en la calidad de la dieta durante la pandemia. Quienes formulen políticas públicas deben considerar la AF cuando promuevan dietas saludables, especialmente en crisis de salud.
RESUMO
Abstract Avoidant or Restrictive Food Intake Disorder (ARFID) is an eating disorder (ED) not common in adults. In this article we present a clinical case of ARFID in a 37-year-old male patient treated in an ED center in Medellin, Colombia; displaying anxious symptoms that began a year earlier and concomitant weight loss, following a traumatic event causing an overall impairment with that patient. Several medical evaluations/examinations looking for organic causes, were excluded. Interventions were implemented by a psychiatry, a psychotherapist using cognitive-behavior therapy (CBT), and a nutritionist, all in face-to-face modality, which were carried out weekly for the first three months, then biweekly and subsequently quarterly. each lasting approximately 40-60 minutes. After the set of pharmacological interventions and psychotherapy, a great improvement in the functionality of the patient was observed. Improvement was found with respect to eating in public, food variation and panic attacks. In the absence of guidelines, it is important to use standardized and replicable treatments in this population.
Resumen El trastorno evitativo restrictivo de la ingesta (TERIA) es un trastorno alimentario (TCA) raro en adultos. Se presenta el caso de un hombre de 37 años con TERIA y trastorno de pánico atendido en un centro para TCA en Medellín, Colombia, quien presentó un año de síntomas ansiosos y pérdida de peso después de evento traumático, generando disfuncionalidad. Fue evaluada y excluida organicidad. Se realizaron intervenciones por parte de psiquiatría, psicoterapia con enfoque cognitivo conductual y nutrición, todas en modalidad presencial, las cuales se realizaron semanalmente los primeros tres meses, luego quincenalmente y posteriormente trimestralmente. Cada una con una duración de 40-60 minutos aproximadamente por sesión. Posterior al conjunto de intervenciones farmacológicas y psicoterapia, se observó una gran mejoría la funcionalidad del paciente, se encontró mejoría con respecto a comer en público, variación en los alimentos y ataques de panico. Ante la ausencia de guías de manejo de TERIA en adultos es relevante realizar tratamientos estandarizados que puedan ser replicados.
RESUMO
Objetivos: Describir la prevalencia del riesgo de deficiencia o exceso en la ingesta de nutrientes y el patrón de consumo de alimentos de acuerdo con las recomendaciones establecidas por el Ministerio de Salud y Protección Social y el Instituto Colombiano de Bienestar Familiar. Materiales y métodos: Se realizó un estudio transversal descriptivo en mujeres sanas que fueron atendidas en dos hospitales del oriente antioqueño, con seguridad alimentaria y nutricional (SAN) según la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA), en el primer trimestre de lactancia, evaluadas entre los años 2021 y 2022. La fuente de información fue la historia clínica. Se midieron las características sociodemográficas, clínicas, antropométricas y la ingesta dietética y de micronutrientes. Se empleó estadística descriptiva. Se presenta la prevalencia de déficit o exceso de ingesta calórica y el índice de relación de consumo (IRC). Se utilizaron los software EVINDI v5, PC-SIDE v1.0, Stata 16.1 y Jasp 0.16.4. Resultados: Se incluyeron 30 mujeres lactantes. La prevalencia de riesgo de deficiencia en la ingesta usual de energía fue 43 % y exceso 16 %; el riesgo de deficiencia proteica fue 98 %. El consumo superior al valor de referencia para grasa saturada fue 86 % y carbohidratos simples 72 %. El patrón de consumo se caracterizó por superar las recomendaciones para azúcares (IRC = 1,29), leche y derivados (IRC = 1,09), cereales, raíces, plátanos y tubérculos (IRC = 1,04). No cumplieron las recomendaciones en la ingesta de grasas (IRC = 0,70), carnes, huevos, leguminosas, frutos secos y semillas (IRC = 0,49), frutas y verduras (IRC = 0,41). Conclusiones: El patrón alimentario identificado dista de las guías nacionales, lo que limita el consumo de macro y micronutrientes, y contribuye al círculo intergeneracional de la malnutrición. Es fundamental realizar nuevas investigaciones en el país para identificar otros patrones de consumo e impulsar acciones de política al respecto.
Objectives: To describe the prevalence of the risk of under or overnutrition and the food intake pattern vis á vis the recommendations of the Ministry of Health and Social Protection and the Colombian Family Welfare Institute. Material and methods: Descriptive cross-sectional study carried out in healthy women receiving care in two hospitals of eastern Antioquia, with food and nutrition security in accordance with the Latin American and Caribbean Food Security Scale (ELCSA), in the first trimester of breastfeeding, assessed between 2021 and 2022. The clinical record was used as the source of information. The sociodemographic, clinical, anthropometric characteristics, as well as dietary and micronutrient intake, were measured. Descriptive statistics were used. The prevalence of deficient or excessive energy intake and the food consumption score (FCS) are presented. The EVINDI v5, PC-SIDE v1.0, Stata 16.1 and Jasp 0.16.4 software packages were used. Results: Overall, 30 breastfeeding women were included. The prevalence of the risk of deficient energy intake was 43 %, while the risk of excessive intake was 16 % and the risk of protein deficiency was 98 %. Intake exceeding the reference value for saturated fats was 86 %, and 72 % for simple carbohydrates. The consumption pattern was characterized by exceeding the recommendations for sugars (FCS = 1.29), milk and dairy products (FCS = 1.09), grains, roots, plantains and tubers (FCS = 1.04). Recommendations for the intake of fats (FCS = 0.70), meats, eggs, legumes, nuts, seeds (FCS = 0.49), fruits and vegetables (FCS = 0.41) were not met. Conclusions: The food intake pattern identified is far from meeting the national guidelines, limiting macro and micronutrient intake and contributing to the intergenerational malnutrition cycle. Additional research in the country is essential in order to identify other intake patterns and drive political action.

El calcio es uno de los nutrientes esenciales para la salud ósea. Objetivos: evaluar la ingesta de calcio en un grupo de mujeres pre-menopáusicas consumidoras de alimentación basada en plantas (ABP). Materiales y métodos: un grupo de mujeres premenopáusicas entre 30 y 45 años consumidoras de ABP fueron invitadas a participar. Para la evaluación de ingesta se empleó un recordatorio alimentario de 24 horas. Se utilizó la Encuesta Nacional de Nutrición y Salud (ENNyS, 2007) como información relevada disponible de ingesta de calcio en nuestra población. En un subgrupo de participantes se evaluó la densidad mineral ósea (DMO) de columna lumbar (L1-L4) por el método de absorciometría de rayos X (DXA), mientras que la microarquitectura fue estudiada a través del trabecular bone score (TBS). Resultados: se incluyeron 30 mujeres con un tiempo de adherencia promedio (X±DS) a la ABP 5,6±4 años, edad de 35,6±4 años, y un índice de masa corporal (IMC) de 23.,7±3 kg/m2. Una ingesta diaria de calcio promedio (IC al 95%) de 980 mg (639 mg-1320 mg) fue observada en las mujeres vegetarianas, mientras que en las veganas fue de 772 mg (460 mg-1085 mg), lo que resulta superior a la de la población general (406 mg). Una correlación positiva fue observada entre DMO e IMC (r=0,990; p=0,01) pero no entre DMO e ingesta de calcio. Conclusiones: en esta cohorte de mujeres premenopáusicas consumidoras de ABP, las vegetarianas y el 96,5% de las veganas cubrieron el requerimiento promedio estimado. La adecuada planificación de la ABP permite evitar deficiencias nutricionales que afecten la salud ósea. (AU)
Calcium is one of the essential nutrients intervening in bone health. Objective: To assess calcium intake in a group of premenopausal women consumers of a plant-based diet (PBD). Materials and methods: Premenopausal women between 30 and 45 y/o consumers of a PBD were invited to participate. A 24-hour food reminder was provided for the intake evaluation. Argentina's National Nutrition and Health Survey (ENNyS, 2007) was used as available information on calcium intake in our population. In a participants' subset, the bone mineral density (BMD) of the lumbar spine (L1-L4) was evaluated by dual-energy X-ray absorptiometry (DXA), while the trabecular bone score (TBS) was used to study the microarchitecture. Results: The study included 30 women with an average adherence time (X±DS) to PBD of 5.6±4 years, of 35.6±4 years and a body mass index (BMI) of 23.7±3kg/m2. An average daily calcium intake (95% CI) of 980mg (639 mg-1.320mg) was observed in vegetarian women, while in vegan women it was 772 mg (460mg-1.085mg), higher than the general population (406 mg). A positive correlation was observed between BMD and BMI (r=0.990; p=0.01), though not between BMD and calcium intake. Conclusions: In this cohort of premenopausal women consuming a PBD, the vegetarians and 96.5% of vegans met the estimated average requirement. An appropriate planning of the PBD prevents nutritional deficiencies that may affect bone health. (AU)

Introducción. La calidad de los carbohidratos consumidos juega un papel importante en la prevención de las enfermedades crónicas no transmisibles (ECNT). Objetivo. Analizar el índice de calidad de los carbohidratos (ICC) en la población urbana costarricense y su relación con las variables sociodemográficas, antropométricas y la calidad y la diversidad de la dieta. Materiales y métodos. Los datos provienen del Estudio Latinoamericano de Nutrición y Salud, en una muestra representativa de 798 personas entre 15 y 65 años que residen en zonas urbanas de Costa Rica (2014- 2015). En una visita domiciliaria se administró un cuestionario para recolectar los datos sociodemográficos y se pesó y midió a los participantes. El consumo dietético se obtuvo mediante dos recordatorios de 24 horas en días no consecutivos. El ICC se calculó mediante el consumo de fibra, el índice glicémico, la relación carbohidratos sólidos/líquidos y la relación granos enteros/granos totales. Se comparó el ICC según el sexo, el grupo de edad, el nivel socioeconómico, el estado nutricional, la circunferencia de cintura y la calidad y diversidad de la dieta de los participantes. Resultados. El ICC se asoció positivamente con un mayor consumo de energía, carbohidratos totales, proteínas, grasas, colesterol, frutas, vegetales y leguminosas (p<0,001). Un mayor ICC se asoció positivamente con un mayor porcentaje de adecuación de micronutrientes y mayor índice de diversidad y calidad de la dieta (p<0,001), así como con un menor índice de masa corporal y una menor circunferencia de cintura al ajustar por sexo y edad (p<0,005). Conclusiones. El presente estudio demostró que un mayor ICC se asocia significativamente con mejores indicadores dietéticos e índice de masa corporal, por lo que resulta fundamental establecer en Costa Rica pautas dietéticas que permitan aumentar la calidad de los carbohidratos de la dieta con el fin de contribuir en la prevención de las ECNT(AU)
Introduction. The carbohydrate quality index (CQI) plays an important role in the prevention of chronic non-communicable diseases (NCD) and adequate macro and micronutrient intake. Objective. To analyze the carbohydrate quality index (CCI) in the Costa Rican urban population and its relationship with sociodemographic and anthropometric variables and the quality and diversity of the diet. Materials and methods. Data come from the Latin American Nutrition and Health Study (ELANS), in a representative sample of 798 people between 15 and 65 years of age who reside in urban areas of Costa Rica (2014-2015). During a home visit, a questionnaire was administered to collect sociodemographic data, and participants were measured and weighed. Dietary intake was obtained through two 24-hour recalls in non- consecutive days. The CQI was calculated using fiber intake, glycemic index, liquid/solid carbohydrate ratio, and whole grain/total grains. CCI was then compared according to sex, age-group, socioeconomic level, nutritional status and diet quality and diet diversity. Results. The CQI was positively associated with energy intake, total carbohydrates, proteins, fats, cholesterol, fruits, vegetables, and legumes (p<0,001). Also, CQI was associated with a higher percentage of micronutrient adequacy and diet quality and diversity (p<0,001), as well as with a lower body mass index and lower waist circumference when adjusting for sex and age (p<0,005). Conclusions. The present study showed that higher CQI is associated with better dietary and body mass index, which shows that it is essential to establish dietary guidelines for public health in Costa Rica that allows increasing the quality of carbohydrates in the diet to contribute to the prevention of chronic NCD(AU)

Introducción. Las preparaciones tradicionales típicas incluyen ingredientes mínimamente procesados, provenientes de la agricultura local, raíces y tradiciones de un territorio. A nivel mundial la población ha cambiado sus patrones dietéticos, incorporando alimentos ultraprocesados impactando la salud poblacional y planetaria. Objetivo. Identificar la sostenibilidad y la prevalencia de consumo de preparaciones tradicionales típicas chilenas en hogares de una región de la zona centro-sur de Chile. Materiales y Métodos. Diseño transversal descriptivo, con una muestra de 104 hogares mediante muestreo no probabilístico por conveniencia. Se identificó la sostenibilidad de 34 preparaciones tradicionales típicas chilenas, aplicando el sistema NOVA de clasificación de los alimentos según grado y tipo de procesamiento. Las preparaciones se clasificaron en sostenibles (>60% de ingredientes del grupo 1), medianamente sostenibles (50-60%) y no sostenibles (<50%). El estudio contó con la aprobación del Comité de Bioética de la Universidad del Bío-Bío. El análisis de datos consideró frecuencias, porcentajes e IC95% en STATA 17.0. Resultados. El 64% de las preparaciones fueron clasificadas como sostenibles, el 23% medianamente sostenibles y un 13% como no sostenibles. Las preparaciones sostenibles son las más consumidas por los hogares, especialmente aquellas que incluyen legumbres. Las preparaciones no sostenibles consumidas en los hogares se basan en harina refinada, manteca vegetal hidrogenado y/o aceites. Conclusiones. La sostenibilidad de las preparaciones tradicionales típicas chilenas depende de sus ingredientes. Las preparaciones sostenibles son las más consumidas por los hogares de esta región, y se basan en alimentos naturales o poco procesados(AU)
Introduction. Typical traditional preparations include minimally processed ingredients from local agriculture, roots and traditions of a territory. Globally, the population has changed its dietary patterns, incorporating ultra-processed foods, impacting population and planetary health. Objective. To identify the sustainability and prevalence of consumption of typical Chilean traditional preparations in households in central-southern Chile. Materials and Methods. Descriptive cross-sectional design, with a sample of 104 households using non-probabilistic convenience sampling. The sustainability of 34 typical Chilean traditional preparations was identif ied, applying the NOVA food classif ication system according to degree and type of processing. The preparations were classif ied as sustainable (>60% of group 1 ingredients), moderately sustainable (50- 60%) and non-sustainable (<50%). The Bioethics Committee of the Universidad del Bío-Bío approved the study. Data analysis considered f requencies, percentages and 95%CI in STATA 17.0. Results. 64% of the preparations were classif ied as sustainable, 23% moderately sustainable, and 13% non-sustainable. Sustainable preparations are the most consumed by households, especially those that include pulses. Unsustainable preparations households consume are based on ref ined flour, hydrogenated vegetable shortening and/or oils. Conclusions. The sustainability of typical Chilean traditional preparations depends on their ingredients. Sustainable preparations are the most consumed by households in this region and are based on natural or minimally processed foods(AU)

Introducción: El consumo de bebidas azucaradas y alimentos no saludables es un problema de Salud Pública y de las Políticas Públicas que buscan reducir el impacto de las Enfermedades No Trasmisibles (ENT) en América Latina. Objetivo: identificar las Políticas Públicas generadas en Colombia, Argentina y Chile para la regulación del consumo de azúcar y comida chatarra. Materiales y Métodos: Análisis exploratorio a través de una revisión de literatura y revisión de documentos normativos. Resultados: Colombia en el año 2021 sancionó la Ley 2120 denominada "Ley de Comida Chatarra", que promueve el acceso a información necesaria para fomentar entornos alimentarios saludables y prevenir las ENT, que incluye nuevas normas para el etiquetado de alimentos y describir sus características al consumidor y así limitar el consumo de alimentos procesados y ultraprocesados. Chile fue pionero en el desarrollo de los sellos de advertencia y desde el año 2014, aplica un impuesto adicional a las bebidas no alcohólicas. Argentina en 2021, sancionó la ley que obliga a la industria de alimentos a disponer de etiquetas en los envases que alerten al consumidor sobre los excesos de azúcares, grasas y sodio Conclusiones: Los tres países investigados cuentan con políticas de etiquetado de alimentos procesados, y en Chile existen impuestos a las bebidas azucaradas. Es importante estudiar el impacto de dichas políticas en la prevalencia y severidad de las ENT y de la caries.
Abstract: The consumption of sugar-sweetened beverages and unhealthy foods is a public health problem that has become a regulatory issue for the public policies aimed at reducing the impact of Non Communicable Diseases (NCDs) in Latin America. Objective: to identify the Public Policies in Colombia, Argentina and Chile for the regulation of the consumption of sugar and junk food. Materials and methods. Exploratory analysis through a literature and policy documents review. Results: In 2021, Colombia approved the Law 2120 called "Junk Food Law" promoting public access to information for a healthy food environment to prevent NCDs. It includes food labeling for overweight and obesity prevention and establishes a specific labeling regulation for processed and ultra-processed food and sweet drink products. Chile was pioneer in the development of warning stamps on food packages and since 2014 also taxes sweet non-alcoholic beverages. In 2021, Argentina approved a law to add labels on food packages to alert consumers about excess of sugars, fats and sodium. Conclusions: The three investigated countries have labeling policies for processed food, and Chile puts taxes on sugary drinks. It is important to study the impact of these policies on NCD prevalence, severity and on dental caries.

En esta revisión se presenta el aspecto teórico de los mecanismos de la sed, además, se discuten los estudios científicos que respaldan o refutan el comportamiento de estos mecanismos en el ejercicio. Finalmente, se hace un resumen de las principales conclusiones extraídas de la literatura científica sobre la sed como un mecanismo suficiente para prevenir la deshidratación tanto durante como después del ejercicio.
Capitán, C. y Aragón, L.F. (2023). Is thirst sufficient as a mechanism for achieving euhydration? a narrative review. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 21(1), 1-16. The role of thirst perception for keeping hydric balance, both during and after exercise, has been extensively studied. However, the way to assess it and the effectiveness of the existing instruments are areas that still require further research. The objective of this review is to integrate, in a general way, the information available in the literature on the functioning of the thirst mechanism as a response to dehydration during and after exercise. The physiological mechanisms and their responses during and after exercise are explained. In addition, a description of the instruments available in scientific literature is included, together with their weaknesses and strengths, and a series of as yet unanswered questions in this area are raised. This review presents the theoretical aspect of thirst mechanisms, and discusses the scientific studies that support or refute the behavior of these mechanisms in exercise. Finally, a summary is made of the major conclusions drawn from the scientific literature on thirst as a sufficient mechanism to prevent dehydration both during and after exercise.

ABSTRACT Background: The nutritional quality of diet may influence the risk of colorectal cancer (CRC). This study compared the Index of Nutritional Quality (INQ) of various dietary components between colorectal cancer patients and healthy controls. Methods: A total of 480 participants were enrolled in the study (160 patients with colorectal cancer as a case group and 320 healthy control). An analysis was conducted on the general characteristics of the participants, their medical histories, anthropometric indicators, physical activity, alcohol consumption, reproductive history, smoking and food intake. A valid food frequency questionnaire was used to assess nutrient intake and INQ was calculated from daily nutrient intake. Results: A Significant inverse association was found between CRC and INQ for vitamins A (OR=0.01, CI: 0.01-0.01), K (OR=0.04, CI: 0.01-0.15), and B12 (OR=0.71, CI: 0.51-0.98), B5 (OR=0.43, CI: 0.00-0.01), zinc (OR=0.35, CI: 0.13-0.95), and phosphorus (OR=0.17, 0.19-0.94). The association between the INQ of vitamin B12 and zinc with colorectal cancer was disappeared after age adjustment. There was a significant negative association between CRC with the INQ of vitamins A, K, B5, phosphorus, and calcium after further adjustments for gender, BMI, menopausal status, and total energy intake. Conclusion: CRC is significantly associated with INQ for some micronutrients. INQ can be considered as an indicator to assess clinical nutritional problems.
RESUMO Contexto: A qualidade nutricional da dieta pode influenciar o risco de câncer colorretal (CCR). Este estudo comparou o Índice de Valor Nutricional (INQ) de vários componentes dietéticos entre pacientes com CCR e controles saudáveis. Métodos: Um total de 480 participantes foram inscritos no estudo (160 pacientes com CCR como um grupo de casos e 320 controles saudáveis). Uma análise foi conduzida sobre as características gerais dos participantes, seus históricos médicos, indicadores antropométricos, atividade física, consumo de álcool, histórico reprodutivo, tabagismo e ingestão de alimentos. Um questionário de frequência alimentar válido foi usado para avaliar a ingestão de nutrientes e o INQ foi calculado a partir da ingestão diária de nutrientes. Resultados: Associação significativa entre CCR e INQ para as vitaminas A (OR=0,00, IC: 0,00-0,01), K (OR=0,04, IC: 0,01-0,15), B12 (OR=0,71, IC: 0,51-0,98) houve uma associação negativa), B5 (OR=0,43, IC: 0,00-0,01), zinco (OR=0,35, IC: 0,13-0,95), fósforo (OR=0,17, IC: 0,19-0,94). A associação entre o INQ da vitamina B12, zinco e CCR desapareceu após o ajuste pela idade. Houve uma associação negativa significativa entre CCR e INQ de cálcio, e outros resultados não mudaram após ajustes adicionais para idade, gênero, Índice de Massa Corporal, estado de menopausa e ingestão total de energia. Conclusão: CCR está significativamente associado ao INQ para alguns micronutrientes. O INQ pode ser usado como um indicador para avaliar problemas nutricionais clínicos.
RESUMO
Introducción: La cantidad diaria recomendada (RDA) de calcio en adolescentes es de 1.300 mg/día. La última Encuesta Nacional de Consumo Alimentario de Chile, mostró que la mediana de ingesta total de calcio fue menos de la mitad de la RDA. Una ingesta insuficiente de calcio puede impactar negativamente la mineralización ósea. Objetivo: Determinar el efecto de la ingesta de calcio y estado nutricional sobre la densidad mineral ósea (DMO) de adolescentes con desarrollo puberal completo. Métodos: Estudio de corte transversal. Participaron n= 79 adolescentes de ambos sexos de entre 17 y 18 años elegidos al azar, aparentemente sanos, estadio Tanner 5 e IMC-1 DE). Según estado nutricional, no hubo diferencias significativas en la ingesta de nutrientes, pero sí en la DMO. En media, la DMO estandarizada (puntaje Z) fue normal para ambos sexos (>-1 DE); los adolescentes con obesidad presentaron una DMO estandarizada significativamente mayor que los adolescentes de peso normal (1,05±0,85 vs 0.33±0,86; P= 0,04). La ingesta de calcio no se relacionó con la masa ósea total ni con la DMO estandarizada. Conclusión: En adolescentes con desarrollo puberal completo no hubo relación entre la ingesta de calcio y los niveles de mineralización ósea. Sí hubo relación entre mineralización ósea y estado nutricional, siendo mayor la DMO en los individuos con obesidad.
Background: In adolescents, the recommended daily intake (RDI) of calcium is 1,300 mg. In Chile, the latest National Survey of Food Consumption showed that the median total calcium intake was less than half of the RDI. An adequate intake of calcium in adolescence negatively affects BMD. Aim: To determine the association of calcium intake and nutritional status with bone mineral density (BMD) in male and female adolescents with completed pubertal development (Tanner 5). Methods: Cross-sectional study in a random sample of 79 male and female adolescents, ages 17-18. Participants were healthy, Tanner stage 5, and BMI −1 SD. BMD was higher in obese participants compared to normal-weight adolescents (1.05±0.85 vs 0.33±0.86; P= 0.04), although no differences in nutrients and food intake. Calcium intake was unrelated to total bone mass and unstandardized BMD. Conclusions: In our sample of adolescents with complete pubertal development, there was no relationship between calcium intake and bone mineralization levels. There was a significant relationship between bone mineralization and nutritional status, with BMD being higher in adolescents with obesity.
RESUMO
Resumen Globalmente, los fármacos son el tipo de agente más frecuentemente implicado en las intoxicaciones pediátricas y las Ben-zodiacepinas el grupo farmacológico más frecuente. La reacción paradojal, secundaria a la exposición a Benzodiacepinas se caracteriza por la presencia de signosintomatología contraria a los efectos sedativos hipnóticos esperados, pudiendo presentarse con inquietud, ansiedad, hostilidad y alteraciones de la conducta, entre otros. La mayoría de los trabajos hallados acerca de este síndrome en pediatría lo describen secundario a Midazolam endovenoso, en contexto de sedación consciente para la realización de diferentes procedimientos. Las causas por los cuales se puede generar este fenómeno de desinhibición no han sido clarificadas, postulándose tres hipótesis: la desregulación colinérgica central, el aumento del tono gabaérgico en el sistema límbico, tálamo e hipotálamo y el desbalance de serotonina. Se expone una serie de 15 pacientes de entre 1 año y 5 años, expuestos accidentalmente a Benzodiacepinas, principalmente Clonazepam y Lorazepam, a fin de describir las características de esta reacción. En esta serie se observó con latencia breve y duración variable, de hasta 11 horas, la presencia en orden de frecuencia, de: ansiedad, irritabilidad, gritos, hostilidad y conductas agresivas, llanto inconsolable, incapacidad de contención por familiares, conductas irracionales, excitación psicomotriz, desinhibición emocional, alucinaciones y aumento de locuacidad, asociado frecuentemente a ataxia.
Abstract Globally, medicines are the most frequently toxins involved in pediatric poisonings, and Benzodiazepines are the most fre-quent pharmacological group in those poisonings. The paradoxical reaction, secondary to Benzodiazepines exposure, is characterized by the presence of contrary expected sedative-hypnotic effects, and may present with restlessness, increased anxiety, hostility, and behav-ioral alterations, among others. The studies we found about this syndrome in pediatric patients describe it most frequently secondary to endovenous Midazolam, in the context of the conscious sedation to perform different procedures. The reasons why this reaction is generated have not been clarified, three hypotheses are postulated: the central cholinergic dysregulation, the increased Gabaergic tone in the limbic system, thalamus and hypothalamus and the serotonin imbalance. A series of 15 patients, between 1 year and 5 years old, accidentally exposed to Benzodiazepines, mainly Clonazepam and Lorazepam, to describe the characteristics of the paradoxical reaction secondary to Benzodiazepines exposure. In this case series, we observed with short latency and variable duration, up to 11 hours, the presence in order of frequency of: anxiety, irritability, screams, hostility and aggressive behaviors, inconsolable crying, inability to con-tain by their family members, irrational behaviors and psychomotor excitement, emotional disinhibition, hallucinations and increased talkativeness, frequently associated with ataxia.
