El etiquetado nutricional: su expresión en el contexto mexicano / Nutritional labeling: its expression in the Mexican context

Introduction: Food is a process that carries implicit socio-cultural elements in a specific historical moment. The changes in the diet caused an increase in problems of obesity and Chronic Non-Communicable Diseases in Mexico. Measures have been taken through public policies that seek to reduce the effects of the consumption of foods with high energy value, one of them is the nutritional labeling of foods. Development: As the first axis, a sociohistorical reconstruction is developed around food labeling in Mexico as an initiative that is part of an international public policy to present nutritional information for the selection and consumption of food. In a second moment, an analysis is carried out from a critical position on the implementation and exercise of decision-making for the consumption of said products, since it is subject to a complex network of sociocultural and individual factors that determine and are determinants of styles. and frequency of consumption of the products. Conclusions: The new labeling with nutritional information is an information tool for the selection in food consumption to face the problem of overweight and obesity in Mexico. However, eating habits and practices respond to sociocultural and economic elements that are above healthy lifestyles and a culture of prevention. It is necessary to build and promote community participation-action that promotes tools such as nutritional labeling to make its objectives effective.

Introducción: la alimentación es un proceso que implica elementos socioculturales en un momento histórico concreto. México se encuentra en un problema de salud generalizado de obesidad y enfermedades crónicas no transmisibles. Ante esto se han tomado medidas mediante políticas públicas que buscan disminuir los efectos del consumo de alimentos de alto valor energético, una de ellas es el etiquetado nutricional de los alimentos. Desarrollo: como primer eje se desarrolla una reconstrucción sociohistórica en torno al etiquetado de alimentos en México como iniciativa que forma parte de una política pública internacional para presentar información nutricional para la selección y consumo de los alimentos. En un segundo momento se realiza un análisis desde un posicionamiento crítico sobre la implementación y el ejercicio de las tomas de decisión del consumo de dichos productos, ya que está sujeta a una compleja red de factores socioculturales e individuales que determinan y son determinantes de los estilos y frecuencia de consumo de los productos. Conclusiones: el nuevo etiquetado con información nutricional es una herramienta de información para la selección en el consumo de alimentos para enfrentar el problema de sobrepeso y obesidad en México. Sin embargo, los hábitos y prácticas de alimentación responden a elementos socioculturales y económicos que están por arriba de los estilos de vida saludable y una cultura de prevención. Es necesario construir y promover una participación-acción comunitaria que potencie las herramientas como el etiquetado nutricional para hacer efectivos sus objetivos.

Etiquetado frontal de advertencia nutricional de alimentos y bebidas pre-envasados. Postura intersectorial de expertos en Centro América y República Dominicana / Front-of-package warning labelling system for pre-packaged foods and beverages: an intersectoral position of expertsin Central American and Dominican Republic

La región latinoamericana ha sido pionera en la implementación del etiquetado frontal de advertencia nutricional (EFAN), mismo que ha demostrado su eficacia y efectividad para identificar correctamente cuando un producto contiene cantidades excesivas de nutrientes asociados a Enfermedades no transmisibles (ENT). Sin embargo, ningún país del Sistema de la Integración Centroamericana (SICA); que incluye a Belice, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panamá y República Dominicana, lo ha adoptado. Por esta razón, el Instituto de Nutrición de Centro América y Panamá, convocó a un grupo de expertos de la academia y la sociedad civil con el objetivo de establecer una postura técnica, basada en la mejor evidencia científica, en relación al etiquetado frontal para los nutrientes críticos de alimentos y bebidas pre- envasados en la región centroamericana. Se presenta evidencia específica de la región del SICA que demuestran la superioridad del EFAN frente a otros etiquetados como las Guías Diarias de Alimentación (GDA), el semáforo y el Nutriscore para seleccionar opciones más saludables. Dentro del marco de los derechos de la niñez y de los consumidores, se brindan argumentos y se hace un llamado a los gobiernos para la pronta adopción del EFAN como una política costo-efectiva para la prevención de ENT. Además, se proveen recomendaciones para su monitoreo y evaluación, así como recomendaciones de otras políticas costo-efectivas como la regulación de la publicidad de alimentos no saludables dirigido a la niñez y adolescencia, entre otros, para la prevención de las ENT y la creación de ambientes y sistemas alimentarios más saludables y sostenibles(AU)

The Latin American region has been a pioneer in the implementation of a front- of-pack warning labeling system (FOPWL), which has demonstrated its efficacy and effectiveness in correctly identifying when a product contains excessive amounts of nutrients associated with Non-Communicable Diseases (NCDs). However, countries of the Central American Integration System (SICA); which includes Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama and the Dominican Republic, have no adopted it. For this reason, the Institute of Nutrition of Central America and Panama convened a group of experts from academia and civil society with the aim of establishing an evidence-based technical position, in relation to front-of-pack labelling for critical nutrients of pre-packaged foods and beverages in the Central American region. Specific evidence from the SICA region demonstrating the superiority of FOPWL over other labels such as the Guideline Daily Amount (GDA), the traffic light and Nutriscore to select healthier choices is presented. Within the framework of children's and consumer rights, arguments are provided, and a call is made to governments for the prompt adoption of FOPWL as a cost-effective policy for the prevention of NCDs. In addition, recommendations for its monitoring and evaluation are provided, as well as recommendations for other cost-effective policies such as the regulation of unhealthy food advertising aimed at children and adolescents, among others, for the prevention of NCDs and the creation ofhealthier and more sustainable environments and food systems(AU)

Determinación de transgenicidad y verificación en el etiquetado de alimentos industrializados de maíz en centros de expendio de Lima metropolitana

Introducción. El consumo de alimentos transgénicos constituye un riesgo potencial para la salud. Sin embargo, en el Perú se carece de información actualizada y confiable sobre la presencia de transgénicos en los alimentos y sobre los datos pertinentes en su etiquetado; de igual manera sobre los alimentos que consumen los animales de abasto, cuyos productos van a ser ingeridos por el humano. Objetivo. Determinar la transgenicidad, mediante la detección del promotor 35S, en productos alimenticios industrializados de maíz para consumo humano y animal, que se comercializan en Lima y verificar sí en el etiquetado se menciona si contiene o no secuencias transgénicas. Métodos. Se analizaron 30 muestras de alimentos para consumo humano y 10 para consumo de animales de abasto; y se revisó el etiquetado. Para la extracción del ADN se utilizó el kit Dneasy Mericon Food, para la detección del P35S el método Real Time-PCR empleando el kit Mericon Screen 35S y para determinar la concentración de copias el kit Mericon Quant Mon 810. Resultados. Se detectó el P35S en el 66,66% de las muestras para consumo humano, y en el 90,00% de las muestras para consumo animal. En el etiquetado del 100% de las muestras para consumo humano y animal no se menciona si contiene o no componentes transgénicos. Conclusiones. La detección de contenido transgénico en la mayoría de los alimentos industrializados de maíz para humanos y animales evidencian la necesidad de su mención en el etiquetado y de la implementación de una política exigente en bioseguridad alimentaria.

Introduction. Consumption of transgenic foods constitutes a potential health risk. However, in Peru there is a lack of updated and reliable information on the presence of transgenics in food and on the relevant data on their labeling; in the same way about the food consumed by animals for supply, whose products are going to be ingested by humans. Objetive. To determine the transgenicity, through the detection of the 35S promoter, in industrialized corn food products for human and animal consumption, which are marketed in Lima and to verify if the labeling mentions whether or not it contains transgenic sequences. Methods. 30 food samples for human consumption and 10 for consumption by animals for production were analyzed; and the labeling was revised. The Dneasy Mericon Food kit was used for DNA extraction, the Real Time-PCR method for P35S detection using the Mericon Screen 35S kit, and the Mericon Quant Mon 810 kit to determine the copy concentration. Results. P35S was detected in 66,66% of the samples for human consumption, and in 90.00% of the samples for animal consumption. The labeling of 100% of the samples for human and animal consumption does not mention whether or not it contains transgenic components. Conclusions. The detection of transgenic content in the majority of industrialized corn foods for humans and animals demonstrates the need to mention them on the label and the implementation of a demanding policy on food biosafety.

Aplicación del perfil de nutrientes de la OPS en productos ultraprocesados, inclusive en alimentos fortificados / Application of PAHO's nutrient profile in ultra-processed products, including fortified foods

Resumen Introducción: en la actualidad se recomienda limitar el consumo de productos ultraprocesados por su alto contenido en azúcar, grasas totales, grasas saturadas, grasas trans y sodio. El etiquetado frontal es una estrategia destinada a fortalecer en el consumidor su capacidad de elegir, pero la estrategia de adición de micronutrientes realizada por la industria alimentaria contribuye a que los consumidores sobrestimen su calidad nutricional. El objetivo de este estudio fue analizar según el modelo del Perfil de Nutrientes (PN) de la Organización Panamericana de la Salud (OPS), un grupo de productos ultraprocesados disponibles en el mercado argentino y aplicar el modelo de forma diferenciada en productos fortificados por la industria alimentaria. Materiales y método: estudio de campo, transversal, descriptivo. Se aplicó el perfil de nutrientes considerando: azúcares libres, grasas totales, grasas saturadas, grasas trans y sodio, en productos fortificados y sin fortificación. Cada una de las categorías generales de alimentos: galletitas dulces, alfajores, chocolates, golosinas, helados, cereales, bebidas, dulces untables, snacks salados y lácteos, fueron divididas en subcategorías, integradas por diferentes productos. Se realizó un análisis estadístico descriptivo por subcategorías. Resultados: la muestra se conformó por 682 productos y todos superaron el punto de corte de al menos un nutriente en cantidad excesiva. El 100% de los productos fortificados (n=146) presentó cantidad excesiva de algún nutriente, el 41,1% tuvo un nutriente en cantidad excesiva y el 50,7% dos nutrientes. 95,7-100% de los productos de los grupos cereales de desayuno, chocolatadas, yogures bebibles y en pote, se categorizaron como con cantidad excesiva de azúcares libres. Conclusiones: todos los productos analizados presentaron al menos un nutriente del PN de referencia, en cantidad excesiva. Los mismos productos tenían adición de vitaminas, minerales o fibra. Se visibiliza la necesidad de realizar estudios que investiguen si esta estrategia induce confusión en el consumidor al momento de elegir.

Abstract Introduction: it is currently recommended to limit the consumption of ultra-processed products because of their high content of sugar, total fats, saturated fats, trans fats and sodium. Front labelling is a strategy aimed at strengthening consumer choice, but the micronutrient addition strategy carried out by the food industry contributes to consumers overestimating their nutritional quality. The objective of this study was to analyze, following the model of the Nutrient Profile (PN) of the Pan American Health Organization (PAHO), a group of ultra-processed products available in the Argentine market and apply the model in a differentiated way in products fortified by the food industry. Materials and method: field study, cross-sectional, descriptive. The nutrient profile was applied considering: free sugars, total fats, saturated fats, trans fats and sodium, both in fortified and unfortified products. Each of the general food categories: sweet cookies, alfajores, chocolates, sweets, ice cream, cereals, beverages, spreadable sweets, salty snacks and dairy products, were divided into subcategories, made up of different products. A descriptive statistical analysis by subcategories was performed. Results: the sample consisted of 682 products and all exceeded the cut-off point of at least one nutrient in excessive quantity. 100% of the fortified products (n=146) had an excessive amount of some nutrient, 41.1% had an excess nutrient and 50.7% two nutrients. 95.7-100% of the products of the breakfast cereals, chocolate, drinking and potted yogurts groups were categorized as having excessive amounts of free sugars. Conclusions: all the products analyzed presented at least one nutrient from the reference NP, in excessive quantity. The same products had added vitamins, minerals or fiber. The need for studies to research whether this strategy induces confusion in the consumer when choosing is made visible.

Estimar la cantidad de bebidas y alimentos procesados y ultraprocesados que declaran información nutricional en su empaque y describir las características de esta información, así como determinar la presencia de información nutricional en los productos con octógonos. Materiales y métodos. Se tomaron fotografías del etiquetado de 4404 bebidas y alimentos procesados y ultraprocesados ofertados en supermercados de Lima Metropolitana. La información declarada en la etiqueta se recogió y se registró en la versión móvil y web del Programa de Información de Etiquetas de Alimentos (FLIP por sus siglas en inglés). Se analizaron las variables correspondientes a la declaración de información nutricional, la forma en que se declara dicha información y la declaración de la misma en bebidas y alimentos con octógonos. Resultados. De todos los productos recolectados solo el 71,4% declara algún tipo de información nutricional. De estos, el 13,8% declara la información nutricional en texto y no en tabla, además sólo 56,3% la declara por cada 100 gramos o mililitros. Del total de alimentos con el octógono «Contiene grasas trans¼, sólo 19,2% declara su contenido. Conclusiones. Más de la cuarta parte de bebidas y alimentos envasados expendidos en el mercado peruano no declaran información nutricional de ningún tipo, y de los que declaran, existe una que lo hace en diferentes formatos y unidades. Además, se halló que hay una proporción de bebidas y alimentos para cada tipo de octógono que no declaran la información del nutriente advertido en el mismo.

ABSTRACT Objectives. To estimate the number of processed and ultra-processed beverages and foods that provide nutritional information on their packaging, and to describe the characteristics of this information, as well as to determine the presence of nutritional information on products with octagons. Materials and methods. Photographs were taken of the labels of 4404 processed and ultra-processed beverages and foods marketed in supermarkets in Metropolitan Lima. The information on the label was collected and registered in the mobile and web version of the Food Label Information Program (FLIP). We analyzed variables related to the nutritional information, the way in which such information is declared and the information in beverages and foods with octagons. Results. Only 71.4% of the products had some type of nutritional information. Of these, 13.8% provided the nutritional information as a text and not in a table, and only 56.3% declared it per 100 grams or milliliters. Of the total number of foods with the octagon "Contains trans fats", only 19.2% declared their content. Conclusions. More than a quarter of the beverages and packaged foods in the Peruvian market did not provide nutritional information of any kind, and of those that did, only one did so in different formats and units. In addition, we found that a proportion of beverages and foods for each type of octagon did not declare information of the nutrient that is mentioned in the octagon.

Azul de metileno, opción para la marcación de cáncer colorrectal pre procedimiento mínimamente invasivo. Reporte de caso

El cáncer colorrectal es una patología común que causa aproximadamente 861,000 muertes al año. Se presenta el caso de un paciente masculino de 50 años, con hipertensión arterial y Diabetes mellitus tipo II, con diagnóstico de neoplasia en colon descendente, al cual se le realizó procedimiento mínimamente invasivo, posterior a marcación tumoral con azul de metileno por medio de endoscopia de vías digestiva bajas. Postoperatorio adecuado, sin complicaciones. El tratamiento de elección para el cáncer colorrectal sin metástasis es la exeresis oncológica. Actualmente, el manejo quirúrgico recomendado es por medio de procedimiento mínimamente invasivo, sin embargo, es un desafío puesto que en algunos casos la identificación de la lesión es difícil y adicionalmente requiere una curva de aprendizaje pronunciada. Por lo anterior, utilizamos el azul de metileno para la marcación del tumor previo procedimiento, con excelentes resultados, sin complicaciones. La marcación tumoral con azul de metileno previa al procedimiento mínimamente invasivo es seguro, útil, económico y de bajo riesgo.

Colorectal cancer is a common pathology, causing approximately 861,000 deaths a year. The case a 50-year-old male patient, with arterial hypertension and type II diabetes mellitus, with a diagnosis of neoplasia in the descending colon, which was performed minimally invasive procedure, after tumor marking with methylene blue by means of endoscopy of lower digestive tracts. Adequate postoperative period, without complications. The treatment of choice for colorectal cancer without metastasis is oncological exeresis. Currently the recommended surgical management is by means of a minimally invasive procedure, however, it is a challenge since in some cases the identification of the lesion is difficult and additionally requires a pronounced learning curve. Therefore, we use methylene blue for the marking of the tumor after the procedure, with excellent results, without complications. Methylene blue tumor marking prior to the minimally invasive procedure is safe, useful, inexpensive, and low risk.

A hiperpigmentação da pele, principalmente na região facial, resulta em um incômodo estético que afeta a qualidade de vida do indivíduo, levando a busca por produtos clareadores. Este estudo avaliou a conformidade dos rótulos de cosméticos comercializados como "produtos clareadores de pele", bem como a existência de substâncias clareadoras proibidas neste tipo de produto. Foi realizada uma análise transversal descritiva qualitativa no período de abril a maio de 2022, em busca por cosméticos comercializados em estabelecimentos farmacêuticos e lojas de produtos cosméticos localizadas no município de Juazeiro/BA. Foram selecionados 18 produtos e os desvios de rotulagem identificados com base na legislação utilizada vigente à época do estudo, foram: ausência de informações sobre advertências/restrições de uso e número de registro incompleto, equivalente a 16,7% (n = 3) das amostras. A hidroquinona, proibida nesse tipo de produto, foi encontrada em um cosmético (5,5%). Embora a maioria das amostras analisadas esteja em conformidade com as exigências legais, os resultados evidenciam descumprimentos, indicando a necessidade de uma fiscalização mais rigorosa a fim de evitar possíveis danos à saúde do usuário.

Skin hyperpigmentation, particularly in the facial region, can be an aesthetic nuisance that affects an individual's quality of life, leading them to seek out whitening products. This study evaluated the compliance of cosmetics labels marketed as "skin lightening products", and assessed the presence of whitening substances prohibited in this type of product. A qualitative, descriptive, cross-sectional analysis was conducted between April and May 2022 in Juazeiro, Bahia, Brazil, focusing on cosmetics sold in pharmaceutical establishments and cosmetic product stores. Eighteen products were selected, and labeling deviations identified based on the legislation in force at the time of the study. These included a lack of information on warnings/use restrictions and incomplete registration numbers, affecting 16.7% (n = 3) of the samples. Hydroquinone, prohibited in this type of product by the legislation, was detected in one cosmetic (5.5%). Although most of the analyzed samples comply with legal requirements, the observed non-compliance highlights the need for more stringent inspection to prevent potential harm to user's health.

Prevalencia y factores asociados a la revisión del etiquetado nutricional por adultos en el Perú

Introducción: La ausencia o poca revisión del etiquetado nutricional es muy frecuente, y estas brindan información sobre la calidad de los alimentos que se van a adquirir y consumir. Objetivo: Determinar la prevalencia de la frecuente revisión del etiquetado nutricional (REN) y sus factores asociados. Métodos: Estudio transversal analítico que evalúa los datos de la Vigilancia Alimentaria Nutricional por Etapas de Vida (VIANEV) de 2017-2018. La REN se consideró frecuente cuando el adulto leyó siempre o casi siempre la tabla de nutrientes de productos que adquiere y/o consume. Se hicieron estimaciones y análisis bivariados, se determinaron factores asociados empleando un modelo lineal generalizado de familia Poisson con enlace log bajo imputación múltiple. Resultados: Se encontró que el 62,4% no revisa el etiquetado del contenido nutricional. Solo 14,9% de los adultos lo hace frecuentemente. Para el modelo crudo, la educación superior se asoció con mayor prevalencia de REN (RP=10,79; IC95%: 1,49-78,16); y una menor prevalencia en el área rural (RP=0,47; IC95%: 0,31-0,73) y tener al menos una Necesidad Básica Insatisfecha (RP=0,56; IC95%: 0,33-0 ,98). En el modelo ajustado se encontró asociación para divorciados (RP: 4,24; IC95%: 1,91 a 9,41), convivientes (RP: 1,61; IC95%: 1,04 a 2,47) y quienes consumían 5 a más porciones de fruta o verduras al día (RP: 1,77; IC95%: 1,28 a 2,44). Conclusiones: La revisión de etiquetas nutricionales no es un comportamiento usual en adultos, y su realización se asoció en los divorciados, convivientes y con los que consumen 5 a más porciones de frutas y verduras.

Introduction: The absence or little review of nutritional labeling is very frequent, and these provide information on the quality of the food that is going to be acquired and consumed. Objective: To determine the prevalence of the frequent review of nutritional labeling (REN) and its associated factors. Methods: Analytical cross-sectional study that evaluates the data from the Nutritional Food Surveillance by Life Stages (VIANEV) from 2017-2018. REN was considered frequent when the adult always or almost always read the table of nutrients of the products they purchase and/or consume. Estimates and bivariate analyzes were made, associated factors were determined using a generalized linear model of the Poisson family with log link under multiple imputation. Results: It was found that 62,4% do not review the nutritional content labeling. Only 14,9% of adults do so frequently. For the crude model, higher education was associated with a higher prevalence of REN (PR=10,79; 95%CI: 1,49-78,16); and a lowerprevalence in rural areas (PR=0,47; 95%CI: 0,31-0,73) and having at least one Unsatisfied Basic Need (PR=0,56; 95%CI: 0,33-0,98). In the adjusted model, an association was found for divorcees (PR=4,24; 95%CI: 1,91-9,41), cohabiting (PR=1,61; 95%CI: 1,04-2,47) and those who consumed 5 or more servings of fruit or vegetables per day (PR=1,77; 95%CI: 1,28-2,44). Conclusions: The review of nutritional labels is not a usual behavior in adults, and its performance was associated with divorced people, cohabitants and with those who consume 5 or more servings of fruits and vegetables.

Evaluation of early renal function changes in patients with type 2 diabetes mellitus using BOLD and ASL / 中华放射学杂志

Objective:To noninvasively evaluate the clinical value of early renal function changes in patients with type 2 diabetes mellitus (T2DM) using blood oxygenation level dependent (BOLD) and arterial spin labeling (ASL) MRI.Methods:A total of 63 T2DM patients from Tianjin First Central Hospital from September 2019 to May 2022 were prospectively collected, 30 healthy volunteers (control group) were collected during the same period. According to albumin creatinine ratio (ACR), patients with T2DM were divided into normal albuminuria (NAU, ACR<30 mg/g) group and microalbuminuria (MAU, 30 mg/g≤ACR≤300 mg/g) group, there were 35 and 28 cases respectively. All subjects underwent abdominal BOLD and ASL scans. The values of renal cortical and medullary apparent relaxation rate (R 2*) and renal cortical renal blood flow (RBF) were measured. One-way ANOVA was used to compare the differences in R 2* and RBF among the three groups. Receiver operating characteristic curve was used to analyze relevant parameters to identify the diagnostic effectiveness of each group, and area under the curve (AUC) was compared by Z-test. Results:There were significant differences in renal medullary R 2* and renal cortical RBF among the control group, NAU group and MAU group ( F=45.83, 34.15, P<0.001). There was no significant difference in renal cortical R 2* ( F=2.98, P=0.056). In differentiating the control group from the NAU group, the AUC of renal medullary R 2*, renal cortical RBF and their combined parameters were 0.921 (95%CI 0.827-0.973), 0.704 (95%CI 0.578-0.811), 0.964 (95%CI 0.885-0.994), respectively. The AUC of combined parameters was significantly different from renal cortical RBF ( Z=4.07, P<0.001), but not from renal medullary R 2* ( Z=1.57, P=0.117). In differentiating the NAU from the MAU group, the AUC were 0.898 (95%CI 0.796-0.960), 0.919 (95%CI 0.823-0.973), 0.985 (95%CI 0.881-0.994), respectively. The AUC of combined parameters was significantly different from renal medullary R 2* and renal cortical RBF ( Z=2.39, P=0.017; Z=2.20, P=0.028). Conclusions:The changes of renal oxygenation level and blood flow in early stage of T2DM patients can be evaluated noninvasively and quantitatively using BOLD and ASL. Renal medullary R 2* combined with renal cortex RBF shows better diagnostic efficacy for early renal function changes in diabetes than each single index.

Value of MRI arterial spin labeling technique on the detection of epileptogenic zone in children with drug resistant epilepsy / 中华放射学杂志

Objective:To explore the value of arterial spin labeling (ASL) in detecting epileptogenic zone (EZ) in children with drug-refractory epilepsy (DRE).Methods:From March 2018 to December 2019, 28 children with DRE were collected prospectively in Peking University First Hospital. Structural MRI, ASL sequence, and PET-CT were performed on 28 DRE children. All children underwent surgical treatment. Intraoperative electrocorticogram findings combined with postoperative MRI results were considered the gold standard for locating EZ. A total of 29 EZ were resected in 28 children. Based on the pathological results, the EZ was divided into focal cortical dysplasia (FCD) Ⅰb and Ⅱa group ( n=12), FCD Ⅱ b group ( n=11) and malformation of cortical dysplasia (MCD) group ( n=6). Structural MRI was observed for finding any abnormal changes that could induce epilepsy and was divided into the normal MRI group ( n=13) and the abnormal MRI group ( n=16). The spatial relationship between abnormal areas in the cerebral blood flow (CBF) map and PET images and the gold standard was observed, and the accurate detection rate of EZ was calculated. The region of interest (ROI) on CBF and PET images was drawn. ROIs were defined as EZ, EZ contralateral zone (EZCZ), EZ adjacent zone (EZAZ), EZAZ contralateral zone (EZAZCZ). The CBF and maximum standardized uptake value (SUV max) were measured, and the asymmetry index (AI) value of EZ and EZAZ of CBF and SUV max was calculated respectively. One-way ANOVA was used to compare the difference among 4 regions and 3 pathological types of CBF, SUV max, and AI. The independent sample t-test was used to compare the difference in AI between normal and abnormal MRI groups. Results:In CBF map, the EZ was accurately localized in 89.7% (26/29) of the lesions, in which 24 EZ had decreased perfusion, and 2 EZ had increased perfusion. Among the 24 EZ with decreased perfusion, the CBF of EZ, EZCZ, EZAZ, and EZAZCZ were significantly different( F=8.79, P<0.001). In PET-CT, the EZ was accurately localized in 93.1% (27/29) of the lesions, in which 25 EZ had decreased metabolism, and 2 EZ had increased metabolism. Among the 25 EZ with decreased metabolism, the SUV max of EZ, EZCZ, EZAZ, and EZAZCZ were significantly different ( F=6.40, P=0.001). The AI value of CBF and SUV max of EZ in the abnormal MRI group were larger than those of the normal MRI group, and the difference was statistically significant ( t=3.34, 3.09, P=0.002 , 0.004). There was no statistical difference in the AI values of CBF and SUV max among FCD Ⅰb and Ⅱa group, FCD Ⅱb group and MCD group ( F=2.05, 1.54, P=0.149, 0.234). Conclusions:ASL technology is accurate in detecting EZ. The changes in perfusion and metabolism of normal structural MRI EZ are greater than abnormal structural MRI EZ. There is no obvious difference in CBF and SUVmax changes in different pathological EZ.

Comparison of 3D-arterial spin labeling and digital subtraction angiography in the diagnosis of occlusion and collateral circulation in patients with acute ischemic stroke / 中国医师杂志

Objective:To explore the diagnostic value of 3D-arterial spin labeling (ASL) and digital subtraction angiography (DSA) in the occlusion and collateral circulation (CC) of patients with acute ischemic stroke (AIS).Methods:From January 2019 to June 2020, 53 cases of AIS patients with middle cerebral artery (MCA) occlusion in Langfang Hospital of Traditional Chinese Medicine were selected as the research objects. All patients underwent DSA and 3D ASL examination. According to the gold standard of DSA, the diagnostic value of proximal intra-arterial signal (IAS) in 3D-ASL was observed, and the clinical value of distal IAS in the diagnosis of lateral CC was observed. Univariate and multivariate logistic regression were used to identify risk factors for poor outcome in AIS patients.Results:There were 31 cases with good collateral circulation judged by DSA. Taking DSA as the gold standard, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of digital IAS in diagnosing CC status were 93.55%, 81.82%, 87.88%, 90.00% and 88.68%, respectively. The National Institutes of Health Stroke Scale (NIHSS) score of patients with good CC assessed by 3D-ASL was lower than that of patients with poor CC at admission, and the good prognosis rate at discharge was higher than that of patients with poor CC, with statistically significant difference (all P<0.05). There was no significant difference in clinical data between patients with good CC and those with poor CC, such as gender, age, history of atrial fibrillation, hypertension, diabetes, smoking, drinking, onset to treatment time, treatment methods, etc (all P>0.05). Univariate and multivariate analysis showed that poor CC assessed by ASL was a risk factor for poor prognosis in AIS patients ( OR=5.897, P<0.05). Conclusions:The proximal and distal IAS of 3D-ASL can provide important diagnostic clues for detecting arterial occlusion and collateral perfusion in patients with AIS, and the detection of CC by ASL is of great value for prognosis.

Preparation and Biodistribution of 131I-labeled Hepatoma Nucleic Acid Nanotrain / 中山大学学报(医学科学版)

ObjectiveTo construct 131Ⅰ-labeled hepatoma nucleic acid nanotrain and to explore its feasibility as a new nuclide carrier targeting hepatoma. MethodsThree short nucleic acid chains self-assembled to a long nucleic acid chain after being annealed， and 131Ⅰ-NT was obtained by radioiodine labeling using chloramine T method. The labeling efficiency and radiochemical purity of the nanoparticles were measured by paper chromatography. The stability of the labeled products in vitro at different temperatures and different storage solvents was detected. The specific uptake of nanoparticles by hepatocellular carcinoma cells was observed by laser confocal microscopy， and the radioactive uptake ratio of 131Ⅰ-NT combined with human hepatocellular carcinoma cell HepG2 and normal hepatocyte L02 was measured. The biodistribution of 131Ⅰ-NT was obtained through injecting 131Ⅰ-NT into HepG2 tumor-bearing mice via tail vein. ResultsThe labeling rate of 131Ⅰ-NT was （93.05±0.74） %， and the radiochemical purity post purification was （98.35±0.32） %. Its radiochemical purity in PBS and pure serum at 4℃ for 24 h was （92.77±0.04） % and （89.43±0.2） %， respectively. The radioactivity uptake rate of HepG2 cells was higher than that of L02 cells after 131Ⅰ-NT was incubated with two kinds of cells for 2 h significantly. After injection of 131Ⅰ-NT through tail vein， the radioactive uptake per gram of tumor tissue were （4.9±0.55）%ID/g， （10.12±0.32）%ID/g and （4.25±0.31）%ID/g at 30 min， 1 h and 2 h， respectively. The T/M ratio was 7.33±2.04， 36.54±12.72 and 44.93±7.90 respectively. ConclusionsThe 131Ⅰ-labeled long chain nucleic acid nanotrain was constructed successfully， which possesses relatively high stability in vitro ， and high targeting ability to HepG2 cells in vitro and HepG2 tumor-bearing mouse model. Our study demonstrated that 131Ⅰ-NT may be a potential radionuclide carrier targeting human liver cancer， which provides a new idea for the targeted radionuclide diagnosis and treatment of hepatocellular carcinoma.

Objective To investigate the causes of false-positive results in the 68Ga-labeled fibroblast activation protein inhibitor (68Ga-FAPI-04) PET/CT imaging. Methods The imaging data of 547 patients undergoing 68Ga-FAPI-04 PET/CT examination in the Department of Nuclear Medicine of the Affiliated Hospital of Southwest Medical University from September 2020 to May 2021 were retrospectively collected.Two experienced nuclear medicine diagnostic physicians analyzed the clinical data,relevant imaging examinations,laboratory examinations,pathological results and follow-up results of the patients with false-positive results. Results The 68Ga-FAPI-04 PET/CT imaging of 547 patients showed false-positive results in 99 (18.1%) patients,including 56 males and 43 females.The postoperative pathological examination confirmed false-positive results in 13 patients,including 1 patient of thyroiditis,2 patients of pulmonary tuberculosis,1 patient of bone tuberculosis,2 patients of pulmonary inflammatory pseudotumor,1 patient of pulmonary sarcoidosis,1 patient of pulmonary benign fibroma,1 patient of organic pneumonia,2 patients of renal angiomyolipoma,1 patient of mass pancreatitis,and 1 patient of pancreatic mucinous cystadenoma.The medical history,relevant imaging examination,and long-term follow-up confirmed false-positive results in 86 patients.Specifically,the false-positive uptake in the neck,chest,abdomen,bone joint,and skin occurred in 8 (9.3%),13 (15.1%),5 (5.8%),57 (66.3%),and 3 (3.5%) patients,respectively.Inflammation-related uptake appeared in 83 (83.8%) patients with false-positive imaging results,of which arthritis (23 patients) and osteophyte (29 patients) were the most common.Sixteen (16.2%) patients showed the false-positive uptake related to fibroblasts. Conclusion 68Ga-FAPI-04 PET/CT imaging will show non-malignant tumor false-positive results,which are mainly associated with inflammation and fibroblasts.

Whole grain products in Brazil: the need for regulation to ensure nutritional benefits and prevent the misuse of marketing strategies

ABSTRACT OBJECTIVE This study aims to evaluate the use of "whole grains" claims in food products marketed in Brazil and evaluate the nutrient profile of these products. METHODS Data from 775 grain-based packaged foods collected in Brazil from April to July 2017 were analyzed. Based on the INFORMAS protocol for food labeling, the prevalence of packaged foods with "whole grains" claims was estimated. Information on the list of ingredients was analyzed to evaluate the presence and amount of whole or refined grains in six food groups. The nutrient profiles of the products with and without "whole grains" claims were compared using the Pan American Health Organization (PAHO) nutrient profile model. RESULTS The packages of about 19% of the evaluated products showed "whole grains" claims in their front panel. Of these, 35% lacked any whole grains among their top three ingredients. Breakfast cereals, granola bars, bread, cakes and other bakery products, cookies, and pasta had higher amounts of refined flour than whole grain ingredients in their compositions.We found 66% of products with "whole grains" claims were high in nutrients of concern according to PAHO's criteria. CONCLUSION Our results showed that over a third of the products in Brazil with "whole grains" claims lacked whole grains as one of their main ingredients. Most had a high content of nutrients associated with noncommunicable chronic disease risk factors, indicating the overestimation of their health benefits.

Information on food additives on food labels in Brazil: a critical analysis / Informação sobre aditivos alimentares nos rótulos de alimentos no Brasil: análise crítica

ABSTRACT Questions about the safety of food additives and their consumption have been raised in recent years. The increased exposure to these substances, either by intake of ultra-processed foods or by the broad use and combination of various categories of additives, may be related to higher risks to consumer health. This article comments on the results of a study that quantified and characterized food additives found on the labels of 9,856 packaged foods and beverages available in Brazilian supermarkets. The study adopted a field diary method to record and analyze nonconformities in the lists of ingredients. The objective of this article is to discuss the use of additives identified on the labels and the limitations of Brazilian legislation, which should guarantee the right to information and health.

RESUMO Nos últimos tempos, questões vêm sendo levantadas sobre a segurança no uso de aditivos alimentares e em seu consumo. verificou-se que o aumento da exposição a essas substâncias, seja pela ingestão mais frequente de alimentos ultraprocessados ou pela ampla utilização e combinação de várias categorias de aditivos pela indústria, pode estar relacionado ao maior risco à saúde do consumidor. Um estudo quantificou e caracterizou aditivos alimentares encontrados nos rótulos de 9.856 alimentos e bebidas embalados disponíveis nos supermercados brasileiros. nele, foi adotado um diário de campo para registro de falhas e inconformidades nas informações presentes nas listas de ingredientes, sendo, por fim, analisadas qualitativamente e descritas de forma narrativa. Com base nisso, o objetivo deste comentário é apresentar e discutir o uso desses aditivos identificados nos rótulos e as limitações da legislação brasileira, que deveria garantir o direito à informação e a saúde da população.

Você costuma verificar o rótulo de alimentos? Estudo de base populacional com adolescentes e adultos de Campinas, SP / Do you usually check the food label? Population-based study with adolescents and adults from Campinas, SP

Resumo Introdução A rotulagem de alimentos é uma importante ferramenta de promoção da saúde e de escolhas alimentares saudáveis. Objetivo Estimar a prevalência do hábito de verificar os rótulos de alimentos e fatores associados em adolescentes e adultos, bem como identificar as informações observadas nos rótulos. Método Estudo transversal de base populacional com amostra probabilística por conglomerados em dois estágios, realizado em Campinas/SP (n = 1.792, 10-59 anos). Foram estimadas razões de prevalência e os respectivos intervalos de confiança de 95% e foi desenvolvido modelo de regressão múltipla de Poisson. Resultados A prevalência do hábito de verificar os rótulos de alimentos foi de 49,4% (IC95%: 45,2-53,6). As prevalências foram superiores no sexo feminino, nos adultos, em indivíduos com maior renda, com maior frequência semanal de consumo de frutas, hortaliças cruas, alimentos integrais, com menor frequência de consumo de refrigerantes e que tinham se pesado há menos de um mês. Data de validade, calorias, sódio e gordura foram as informações mais buscadas nos rótulos. Conclusão Os resultados destacam a necessidade de orientar e estimular o uso da rotulagem nutricional, identificam os segmentos prioritários e contribuem para preencher uma das lacunas científicas brasileiras sobre a prevalência de consulta aos rótulos de alimentos e fatores associados.

Abstract Background Food labeling is an important tool for encouraging health and healthy food choices. Objective To estimate the prevalence of food label consultation and associated factors in adolescents and adults, and to identify the information taken from food labels. Method Cross-sectional study with data from population-based surveys with a probabilistic sample, by clusters and in two-stages, conducted in Campinas, São Paulo, Brazil (n=1.792, 10-59 years). Prevalence ratios and respective 95% confidence intervals were estimated and a Poisson multiple regression model was developed. Results 1,792 individuals aged 10 to 59 years participated in the study. The prevalence of reading food labels was 49.4% (95%CI: 45.2-53.6) for the whole population. Prevalence was higher in females, adults, in those with higher income, with more frequent weekly consumption of fruits, raw vegetables, and whole foods, with less frequent consumption of soft drinks, and those who had weighed themselves less than a month ago. Expiration date, calories, sodium and fat were the most searched for information on food labels. Conclusion The results highlight a need to guide and encourage the use of nutrition labeling, identify priority segments and help to fill a scientific gap in Brazil regarding the prevalence of food label consultation and associated factors.

Marketing communication strategies on labels of food products consumed by children / Estratégias de comunicação mercadológica em rótulos de alimentos consumidos por crianças

ABSTRACT OBJECTIVE: Analyze marketing communication strategies (MCS) of labels of food products consumed by children under 5 years of age from the Brazilian National Health System (SUS) in the city of Rio de Janeiro. METHODS: In total, 390 labels of ultra-processed foods and industrialized baby foods were analyzed. The products were organized by similarity into 24 groups. Photographs of labels from each group were analyzed to identify the MCS, which were categorized into "presence of characters and/or celebrities," "emotional appeal," "freebies offering," "health appeal," "sensory stimulation," "brand or slogan use," "promotional price," "advertisement under advertisement," and "sustainability appeal." The percentage frequency of labels according to the number of MCS per label; the total and average frequency of MCS according to the food group; the frequency of MCS type according to the food group; and communication resources by type of MCS were computed. RESULTS: 1 to 19 strategies were found per label and an average of 7.2 MCS per label, totaling 2,792 occurrences. The MCS "sensory stimulation," "health appeal," "brand or slogan use," and "advertisement under advertising" were observed in all food groups. "Freebies offering" and "promotional price" were observed in eight and six food groups, respectively. In food groups of bread; dairy products; and sweets, candies, and goodies, all nine types of MCS included in the study were identified. The groups that presented fewer types of MCS (n=5) were: peanuts, instant noodles, and margarines. Of the total MCS identified on the labels, the most frequent were "sensory stimulation" (29.4%) and "health appeal" (18.2%); and the least frequent were "freebies offering" (0.8%) and "promotional price" (0.4%). The "emotional appeal" strategy presented the highest diversity of communication resources. CONCLUSION: Rigorous regulatory measures are required to protect consumers from massive exposure to MCS on food labels.

RESUMO OBJETIVO: Analisar estratégias de comunicação mercadológica (ECM) presentes em rótulos de produtos efetivamente consumidos por crianças menores de 5 anos usuárias do Sistema Único de Saúde na cidade do Rio de Janeiro. MÉTODOS: Foram analisados 390 rótulos de alimentos ultraprocessados e papas infantis industrializadas. Os produtos foram organizados por similaridade em 24 grupos. Realizou-se a análise das fotografias dos rótulos de cada grupo para a identificação das ECM, que foram categorizadas em: "presença de personagens e/ou celebridades", "apelo emocional", "oferta de brindes", "apelo à saúde", "estímulos aos sentidos", "uso da marca ou slogan", "preço promocional", "propaganda sob propaganda" e "apelo à sustentabilidade". Foram computadas: frequência percentual de rótulos segundo número de ECM por rótulo; frequência total e média de ECM segundo grupo de alimentos; frequência do tipo de ECM segundo grupo de alimentos; e recursos comunicacionais por tipo de ECM. RESULTADOS: Constataram-se de uma a 19 estratégias por rótulo e média de 7,2 ECM por rótulo, totalizando 2.792 ocorrências. As ECM "estímulo aos sentidos", "apelo à saúde", "uso da marca ou slogan" e "propaganda sob propaganda" foram observadas em todos os grupos de alimentos. Já "oferta de brindes" e "preço promocional" apareceram em oito e seis grupos de alimentos, respectivamente. Nos grupos pães, lácteos e doces, balas e guloseimas, foram identificados os nove tipos de ECM incluídos no estudo. Os grupos que apresentaram menos tipos de ECM (n = 5) foram: amendoins, macarrões instantâneos e margarinas. Do total de ECM identificadas nos rótulos, as mais recorrentes foram "estímulo aos sentidos" (29,4%) e "apelo à saúde" (18,2%); e as menos frequentes foram "oferta de brindes" (0,8%) e "preço promocional" (0,4%). A ECM "apelo emocional" apresentou a maior diversidade de recursos comunicacionais. CONCLUSÃO: São necessárias medidas regulatórias rigorosas que protejam o consumidor da massiva exposição às ECM em rótulos de alimentos.

(In)segurança da rotulagem de alimentos infantis à base de cereais em relação à legislação brasileira vigente / (In)safety of labeling of cereal-based infant foods in relation to current brazilian legislation

Introdução: Os cereais sãoamplamente utilizados na alimentação das crianças. Objetivo: avaliar a composição nutricional e a rotulagem de alimentos infantis à base de cereais, em relação à legislação vigente. Material e Métodos: Estudo transversal, analítico e descritivo que avaliou alimentos à base de cereais, bem como a conformidade da rotulagem em relação à legislação brasileira vigente. Resultados: Avaliaram-se 72 amostras de alimentos: cereal para alimentação infantil; mistura para o preparo de mingaus e farinha de cereais; 100% das amostras apresentaram alguma não conformidade em relação à legislação, incluindo a presença de falso conceito de vantagem e segurança, ilustrações não permitidas, ausência de advertências obrigatórias e ausência da idade mínima para consumo do produto. Nas análises bromatológicas e de rotulagem, o teor de carboidratos de todas as categorias ultrapassou 80% do valor energético total do produto. Os teores de proteínas, lipídios, carboidratos e energia da categoria cereal para alimentação infantil mostraram diferenças significativas, sendo, respectivamente, p=0,015, p<0,001, p=0,013 e p<0,001. A categoria "mistura para preparo de mingaus" também mostrou diferenças significativas para proteínas, lipídios, carboidratos e energia (p<0,001). Na categoria de farinhas de cereais, somente o teor de proteínas apresentou diferença (p=0,05). Conclusão: Considerando o universo amostral do estudo, é possível concluir que mesmo na vigência de legislações específicas, ainda encontramos não conformidades legais na rotulagem de alimentos à base de cereais destinados à alimentação infantil, sendo que esses alimentos apresentam composição nutricional diferente das informações apresentadas em seus rótulos, impactando negativamente a segurança alimentar de crianças.

Introduction: Cereals are widely used in children's nutrition. Objective: to evaluate the nutritional composition and labeling of cereal-based infant foods, in relation to current legislation. Material and Methods: cross-sectional, analytical and descriptive study that evaluated cereal-based foods, as well as labeling compliance with current Brazilian legislation. Results: 72 food samples were evaluated: cereal for baby food; mixture for the preparation of porridge and cereal flour. One hundred percent of the samples showed some non-compliance with the legislation, including the presence of a false concept of advantage and safety, illustrations not allowed, absence of mandatory warnings and, absence of the minimum age for consumption of the product. In bromatological and labeling analyses, the carbohydrate content of all categories exceeded 80% of the total energy value of the product. The protein, lipid, carbohydrate and energy contents of the cereal category for infant feeding showed significant differences, being, respectively, p=0.015, p<0.001, p=0.013 and p<0.001. The mix category for porridge preparation also showed significant differences for proteins, lipids, carbohydrates and energy (p<0.001). In the category of cereal flours, only the protein content showed a difference (p=0.05). Conclusion: considering the sample universe of the study, it is possible to conclude that even in the presence of specific legislation, we still find legal non-conformities in the labeling of cereal-based foods intended for infant feeding, and these foods have a nutritional composition different from the information presented on their labels, negatively impacting children's food safety.

Coexistence of high content of critical nutrients and claims in food products targeted at Brazilian children / Coexistência de altos teores de nutrientes críticos e alegações em produtos alimentícios voltados para crianças brasileiras

ABSTRACT Objective: This study aimed to evaluate food labels targeted at children and identify the concomitant presence of claims and high levels of critical nutrients and/or the presence of sweeteners. As a secondary objective, it aimed to list different types of claims and check which marketing strategies are most used. Methods: We collected 409 products, from 8 popular food groups targeted at children, in Brazilian market (i.e., fruit drinks, dairy drinks, sandwich cookies, cakes, breakfast cereals, jellies, corn snacks, and yogurts). The contents of critical nutrients (e.g., sugar, total fat, saturated fat, and trans-fat, and sodium) and presence/absence of sweetener were calculated, considering Pan American Health Organization (PAHO) parameters. Then, we verified the presence and types of claims in these products. Results: Overall, 265 (64.7%) labels presented claims. In three of the eight categories (i.e., breakfast cereals, dairy drinks, and yogurt), all products with claims (50, 34, and 34 products, respectively) had one or more nutrients in harmful concentrations (critical nutrients above PAHO's nutritional profile and/or presence of sweeteners). In the other categories, only one product (of 63 sandwich cookies and 26 breakfast cereals with claims) and three products (of 22 cakes and 28 jellies with claims) had no nutrient in critical concentration. The presence of claims, like "rich/source" of micronutrient, was predominant in seven of the eight food groups. Conclusion: In the present study, there was a high presence of claims, of different types, in foods targeted at children, which, for the most part, also have excess of at least one critical nutrient, according to PAHO.

RESUMO Objetivo: Avaliar rótulos de alimentos direcionados ao público infantil e identificar a presença concomitante de alegações e de altos teores de nutrientes críticos e/ou presença de adoçantes. Como objetivo secundário, listar os diferentes tipos de alegações e verificar quais estratégias de marketing são mais utilizadas. Métodos: Foram coletados 409 produtos provenientes das oito categorias de alimentos mais populares entre crianças brasileiras (bebidas à base de frutas, bebidas lácteas, biscoitos recheados, bolos, cereais matinais, gelatinas, salgadinhos de milho e iogurtes). Foram calculados os teores de nutrientes críticos (açúcares, gorduras totais, saturadas e trans e sódio) e presença/ausência de adoçante, considerando-se os parâmetros da Organização Pan-Americana de Saúde (OPAS). Em seguida, verificamos a presença e os tipos de alegações nesses produtos. Resultados: No total, 265 (64,7%) rótulos apresentaram alegações. Em três das oito categorias (cereais matinais, bebidas lácteas e iogurtes), todos os produtos com alegações (50, 34 e 34 produtos, respectivamente) continham um ou mais nutrientes em concentrações prejudiciais (nutrientes críticos acima do preconizado pela OPAS e/ou presença de edulcorantes). Nas demais categorias, apenas um produto (de 63 biscoitos recheados e 26 cereais matinais com alegação) e três (de 22 bolos e 28 gelatinas com alegação) não apresentavam nutrientes em concentração crítica. A presença de alegações, como "rico" ou "fonte" de micronutriente, foi predominante em sete dos oito grupos de alimentos. Conclusões: Observou-se alta presença de alegações, de diferentes tipos, em alimentos destinados a crianças, que, em sua maioria, também possuem excesso de pelo menos um nutriente crítico, de acordo com a OPAS.
