Introdução: os primeiros anos de vida são essenciais para o crescimento e o desenvolvimento. A criança já nasce com a preferência pelo sabor doce, e ao consumir preparações açucaradas, propicia--se uma alimentação de baixa qualidade nutricional. O objetivo do estudo é descrever a ingestão de alimentos que contenham açúcar por crianças com dificuldades alimentares menores de 2 anos atendidas em um centro especializado. Material e métodos: trata-se de um estudo observacional retrospectivo, com dados obtidos do prontuário de crianças de ambos os sexos, atendidas no Centro de Excelência em Nutrição e Dificuldades Alimentares (CENDA), localizado no município de São Paulo. Dentre os alimentos consumidos foram selecionados aqueles que continham açúcar de adição em sua composição. Para categorizar os alimentos foi usada a classificação da What We Eat in America (WWEIA). Resultados: participaram do estudo 31 crianças com dificuldades alimentares, 77,4% apresentaram consumo de pelo menos um alimento contendo açúcar. Os alimentos mais consumidos foram biscoitos e brownies, bolos e tortas, milk-shakes e outras bebidas lácteas. Discussões e Conclusão: a fase de alimentação complementar pode se tornar um grande desafio para os pais e cuidadores, a mesma foi o ponto de partida para a maioria das crianças com dificuldade alimentares. O aprendizado do comer é um processo complexo que exige aquisição de habilidades na oferta de alimentos adequados e variados, contudo, o contexto se torna favorável com as práticas inadequadas, sendo uma delas a permissão do consumo de alimentos e produtos adoçados pelas mesmas.
Introduction: the first years of life are essential for growth and development. Children are born with a preference for sweet tastes, and through sugary consumption, they are provided with a diet of low nutritional quality. The objective of the study is to describe the intake of foods containing sugar by children with eating difficulties under 2 years of age treated in a specialized center. Material and methods: this is a retrospective observational study, with data obtained from the medical records of children of both sexes, attended at the Center for Excellence in Nutrition and Eating Difficulties (CENDA), located in the city of São Paulo. Among the foods consumed, those that contained added sugar in their composition were selected. To categorize foods, the What We Eat in America (WWEIA) classification was used. Results: 31 children with eating difficulties participated in the study, 77.4% consumed at least one food containing sugar. The most consumed foods were cookies and brownies, cakes and pies, milkshakes and other dairy drinks. Discussions and Conclusion: the complementary feeding phase can become a great challenge for parents and caregivers, as it was the starting point for the majority of children with eating difficulties. Learning to eat is a complex process that requires the acquisition of skills in offering adequate and varied foods. However, the context becomes favorable to inappropriate practices, one of which is allowing the consumption of sweetened foods and products, for the same reasons.

Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.
La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

ObjectiveTo explore the metabolic changes during the development of Tupaia belangeri breast tumors, to investigate the close relationship between the changes of serum metabolic substances and the occurrence and progression of tumors, and to screen for biomarkers reflecting the progression of breast tumors. MethodsBreast tumors in Tupaia belangeri were induced by orally administering 7,12-dimethylbenzoanthracene (DMBA) three times, with a 15-day interval between each administration, along with a high-fat and high-sugar diet. The DMBA-induced breast cancer group and the DMBA-inducedwithout breast cancer group were compared with the control group. Untargeted determination of serum metabolites was performed using gas chromatography-time-of-flight mass spectrometry (GC-TOFMS) in DMBA-induced Tupaia belangeri with breast cancer, DMBA-induced without breast cancer and the control group. Multidimensional statistical analysis including unsupervised principal component analysis (PCA), and orthogonal partial least squares analysis (OPLS-DA) were conducted. Furthermore, t-test was used for intergroup differential comparison. Differential metabolites were screened under VIP>1 and P<0.05 conditions, and significantly changing differential metabolites were identified using the HMDB online database. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database was utilized to enrich metabolic-related gene regulatory pathways. ResultsThe incidence of breast tumors was 40% in DMBA-induced Tupaia belangeri. Compared with the control group, 30 metabolic differential products were detected in the serum of the group with breast cancer, with 18 down-regulated and 12 up-regulated (VIP>1, P<0.05). KEGG pathway analysis revealed significant changes in four metabolic pathways: glutamate metabolism, glyceride metabolism, citric acid cycle, and alanine metabolism. Compared with the group without breast cancer, 18 metabolic differential products were detected, with 7 down-regulated and 11 up-regulated (VIP>1, P<0.05). KEGG pathway analysis revealed significant changes in the citric acid cycle and glutamate metabolism. Compared with the control group, 31 metabolic differential products were detected in the serum of the groups without breast cancer, with 14 down-regulated and 17 up-regulated (VIP>1, P<0.05). KEGG pathway analysis revealed significant changes in three metabolic pathways: glutamate metabolism, glyceride metabolism, and citric acid cycle. ConclusionMetabolomics analysis can reveal the characteristics of changes in metabolites in the serum of breast tumors. The results suggest that glutamate metabolism, glyceride metabolism, citric acid cycle, and alanine metabolism pathways are associated with the occurrence and development of DMBA-induced breast tumors in Tupaia belangeri. It provides a foundation for further research into the biological mechanism of breast cancer.

Objective@#To explore the effects of different concentrations of glucose solution on the survival of Aedes albopictus and Culex pipiens pallens larvae, the attraction to mosquitoes and egg-laying behaviors, so as to provide the reference for developing mosquito control technology based on sugar bait.@*Methods@#White porcelain bowls were filled with 100 mL of 3%, 5%, 8%, 10% and 15% glucose solutions. Ten of fourth instar larvae of Aedes albopictus or Culex pipiens pallens were added to each bowl, and the survival of larvae was recorded after 2, 4, 6, 24, 48 and 72 hours. Egg-laying cups containing 5%, 8% and 15% glucose solution were put in mosquito cages containing fully blooded female mosquitoes of Aedes albopictus and Culex pipiens pallens (50 mosquitoes each), and the total number of eggs laid in 72 hours was observed. The analogous site room was filled with fully blooded and starved female mosquitoes of Aedes albopictus and Culex pipiens pallens (100 mosquitoes each), and simple mosquito control buckets containing 5% and 8% glucose solution and black sticky insect plates. The number of mosquitoes and eggs was observed after 6 days. All the above experiments were repeated 3 times using dechlorinated water as the control.@*Results@#The 72 hour corrected mortality rates of Aedes albopictus and Culex pipiens pallens larvae gradually increased with the increase of glucose concentration. The glucose solution with 5% and higher concentrations was not suitable for mosquito larvae to survive. The attraction of egg-laying behaviors to Aedes albopictus and Culex pipiens pallens gradually decreased with the increase of glucose concentration. The effects were similar between 5% and 8% glucose solution, with the averages of 686.67 and 682.33 eggs for Aedes albopictus, and 3.00 and 2.33 egg rafts for Culex pipiens pallens. In analogous site room, there were 93.33, 105.00 and 130.33 adult mosquitoes captured on average in the control group, 5% and 8% glucose solution groups, respectively, with 8% glucose solution group more attractive to adult mosquitoes than the control group (F=3.283, P=0.030); there were 70.33, 55.33 and 63.00 Aedes albopictus eggs (eggs counts+larvae counts) on average, respectively, with statistically significant differences among the three groups (H=6.761, P=0.034).@*Conclusion@#Glucose solution with concentration of 5% or higher can effectively inhibit the survival of Aedes albopictus and Culex pipiens pallens larvae, and attractive to adult mosquitoes and egg-laying behavoirs.

Protein as the allergens could lead to allergy. In addition, a widespread class of allergens were known as glycans of N-glycoprotein. N-glycoprotein contained oligosaccharide linked by covalent bonds with protein. Recently,studies implicated that allergy was associated with glycans of heterologous N-glycoprotein found in food, inhalants, insect toxins, etc. The N-glycan structure of N-glycoprotein allergen has exerted an influence on the binding between allergens and IgE, while the recognition and presentation of allergens by antigen-presenting cells (APCs) were also affected. Some researches showed thatN-glycan structure of allergen was remodeled by N-glycosidase, such as cFase I, gpcXylase, as binding of allergen and IgE partly decreased. Thus, allergic problems caused by N-glycoproteins could potentially be solved by modifying or altering the structure ofN-glycoprotein allergens, addressing the root of the issue. Mechanism of N-glycans associated allergy could also be elaborated through glycosylation enzymes, alterations of host glycosylation. This article hopes to provide a separate insight for glycoimmunology perspective, and an alternative strategy for clinical prevention or therapy of allergic diseases.

Glycosylation is one of the most important reactions in living organisms as it results in the formation of glycoconjugates with diverse biological functions. Sugar nucleotides are structurally composed of sugar and nucleoside diphosphate or monophosphate, which are widespread within a variety of biological cells. As glycosyl donors for the transglycosyl reactions catalyzed by Leloir-type glycosyltransferases, sugar nucleotides are essential for the synthesis of glycans and glycoconjugates. However, high costs and limited availability of nucleotide sugars prevent applications of biocatalytic cascades on an industrial scale. Therefore, attentions on synthetic strategies of sugar nucleotides have been increasing to achieve their wide applications in various fields. The 9 common sugar nucleotides in mammals have been fully studied with large-scale synthesis through chemical, enzymatic (chemo-enzymatic) and cell factory strategies. In addition to common sugar nucleotides, many rare sugar nucleotides are present in plants and bacteria. Although unnatural sugar nucleotides cannot be synthesized in organisms, they have great potential in research as substrates for glycosyltransferases in carbohydrate synthesis, as enzyme inhibitors in biochemical studies, and as components of glycoconjugate biosynthesis. Therefore, increasing attention has been paid to explore the efficient synthesis of unnatural sugar nucleotides. Currently, strategies for chemical synthesis of sugar nucleotides have been greatly improved, such as the use of effective catalysts for forming pyrophosphate bonds and the development of entirely new synthesis protocols. Multiple sugar nucleotides, especially unnatural sugar nucleotides, are synthesized chemically. However, chemical synthesis requires tedious protection and deprotection steps, resulting in complex steps, high cost and low yield. In contrast, enzymatic (chemo-enzymatic) and cell factory methods have significant advantages such as high yield, easy operation and easy process scale-up in the preparation of sugar nucleotides. Hence, they are prominent strategies for sugar nucleotide preparation. Herein, the biosynthesis and application of sugar nucleotides are reviewed, mainly focusing on the 9 sugar nucleotides common in mammals. The early strategies for enzymatic synthesis of sugar nucleotides generally used de novo synthesis pathway. With the discoveries of enzymes involved in salvage pathway of sugar nucleotide synthesis and the development of one-pot multienzyme (OPME) method, the synthesis of sugar nucleotides was greatly simplified. Cell factory method employs the microbial living cells as a “processing plant” by engineering their metabolic pathways through genetic engineering technology. The cell factory method has high yield, and has been applied for efficient synthesis of several sugar nucleotides. Moreover, the strategy of gram-scale synthesis of multiple rare sugar nucleotides by cascade reactions from common sugar nucleotides using sugar nucleotides synthases cloned from different sources was illustrated. In recent years, the synthesis cost of sugar nucleotides has been further reduced through various ways, such as regeneration of nucleotides, regeneration of organic cofactors, and application of immobilized enzyme technology. Furthermore, through the continuous improvement of sugar nucleotide purification process, the use of high concentration of multi-enzyme cascade and rapid non-chromatographic purification process, the synthesis of multiple sugar nucleotides and their derivatives from monosaccharides was achieved, which gradually broke the limitations of the existing strategy. With the efficient synthesis of sugar nucleotides, their applications in various fields have been increasingly explored, including the synthesis of glycans and glycoconjugates, biochemical characterization of glycosyltransferases and bioorthogonal labeling strategies, which are of great significance to the research of biochemistry, glycobiology and the development of related pharmaceutical products.

@#Introduction: The consumption of sugar-sweetened beverages (SSBs) among young adults in Malaysia has witnessed a notable increase in recent years, giving rise to concerns regarding the potential adverse health effects, including obesity and diabetes. Despite the urgent need for targeted interventions, there is a dearth of research examining the knowledge, attitudes, and practices (KAP) related to SSBs among Malaysian young adults. To address this research gap, the present study aims to assess the level of KAP concerning SSB intake and its associated factors in this specific population. Methods: A cross-sectional study was conducted involving 408 Malaysian young adults aged between 15 and 29 years. Respondents completed an online questionnaire survey, which encompassed the assessment of socio-demographic characteristics and KAP regarding SSB consumption. The collected data were analyzed using IBM’s Statistical Package for the Social Sciences (SPSS) version 22.0. Spearman correlation tests were performed at a significance level of 0.05. Results: The majority of respondents demonstrated moderate knowledge (60%) and practices (60%), while exhibiting a high positive attitude (100%) towards reducing SSB consumption. Significant correlations were observed between knowledge and attitude (p = 0.003, rs = 0.148) and between knowledge and practice (p = 0.005, rs = 0.138). Moreover, the attitude scores were found to be significantly associated with gender (χ2 (1, N = 408) = 10.421, p = 0.001) and locality (χ2 (1, N = 408) = 4.106, p = 0.043), while the practice scores exhibited a significant association with ethnicity (p = 0.006). Conclusion: This study provides valuable insights into the relationship between KAP related to SSB consumption and socio-demographic factors among Malaysian young adults. The findings underscore the importance of utilizing these insights to develop strategic interventions that aim to curtail SSB consumption and promote a healthy lifestyle, ultimately contributing to the reduction of non-communicable diseases. Health authorities are encouraged to capitalize on these findings to design targeted interventions tailored to the unique needs and circumstances of this population.

ABSTRACT Objective. To examine sociodemographic differences in the awareness, understanding, use and effect of nutrition labels among Mexican and Chilean youth. Methods. Online surveys among youth (10-17 years) were obtained in 2019 (n=2631). Participants reported their awareness, understanding, and use of their country-specific nutrition facts tables (NFT) and front-of-pack labels (FOPL) (Chile: warning labels [WLs]; Mexico: guideline daily amounts [GDA]). Additionally, participants reported their perceived healthfulness of a sweetened fruit drink after viewing one of six versions of it with different FOPL (no-label control, Health Star Rating, WLs, GDAs, Traffic Light, or Nutri-Score) during an experimental task. Results. Higher self-reported nutrition knowledge was associated with higher NFT and FOPL awareness, understanding, and use, except for WL use. WLs were the most effective FOPL in decreasing the perceived healthfulness of the sweetened fruit drink compared to a no-label condition and other FOP labels. In Chile, the effect of GDA differed by income adequacy, while in Mexico Nutri-Score differed by age. Conclusions. Results suggest that nutrition label awareness, use, understanding, and impact differ across demographics, favoring higher income and nutrition knowledge. Despite this, WLs are likely to have a positive impact on nutrition-related knowledge and behaviors among Mexican and Chilean youth, independently of their socio-demographic groups.
RESUMEN Objetivo. Examinar las diferencias sociodemográficas por lo que respecta al conocimiento, la comprensión, el uso y el efecto de las etiquetas nutricionales en adolescentes de México y Chile. Métodos. En el 2019 se efectuó una encuesta en línea en adolescentes (10 a 17 años) (n=2631). Los participantes indicaron su conocimiento, comprensión y uso de los cuadros de información nutricional y los etiquetados frontales específicos de los empaques de su país (en el caso de Chile, las etiquetas de advertencia, y en el de México, las guías diarias de alimentación (GDA). Asimismo, se llevó a cabo un experimento en el que los participantes indicaron su percepción de lo saludable que era una bebida de fruta azucarada después de ver una de sus seis versiones con diferentes etiquetas frontales en los envases (control sin etiqueta, calificación de producto saludable mediante estrellas Health Star, etiquetas de advertencia, GDA, colores del semáforo, o sistema Nutri-Score). Resultados. El autorreporte de un mayor conocimiento sobre nutrición por parte de los participantes se asoció a un mayor conocimiento, comprensión y uso de los cuadros de información nutricional y los sistemas de etiquetado frontal, excepto en el caso del uso de las etiquetas de advertencia. Las etiquetas de advertencia fueron el sistema de etiquetado frontal más eficaz para reducir la percepción saludable del producto con respecto a la bebida de fruta azucarada, en comparación con la ausencia de etiqueta y el resto de los etiquetados frontales. En Chile, el efecto de las GDA variaba en función de la adecuación del ingreso, mientras que en México el efecto del Nutri-Score difería según la edad. Conclusiones. Los resultados sugieren que el conocimiento, el uso, la comprensión y el efecto de las etiquetas nutricionales difieren entre los distintos grupos demográficos, de tal manera que son más favorables en las personas con mayores ingresos y conocimientos de nutrición. A pesar de esto, es probable que las etiquetas de advertencia tengan un impacto positivo sobre los conocimientos y los comportamientos relacionados con la nutrición en los adolescentes de México y Chile, con independencia de los grupos sociodemográficos de los que forman parte.

Resumen La relación entre el consumo de bebidas endulzadas con sacarosa y la reducción en la ingesta de alimentos ha sido objeto de estudio en el ámbito de la salud pública y la nutrición. A medida que el consumo de estas bebidas ha aumentado en las últimas décadas, se ha observado un aumento de los problemas de salud relacionados con la alimentación. En este trabajo se analiza el efecto que tiene la ingesta crónica de agua endulzada con sacarosa sobre el consumo de alimento balanceado, el perfil lipídico, la resistencia a la insulina, y en algunos marcadores del estado nutricional como el peso, la proteína sérica total, albúmina, hemoglobina y creatinina en ratas Wistar macho. El agua endulzada con sacarosa al 12% se administró a un grupo de 9 ratas durante 8 semanas. Un grupo control de 9 ratas bebieron agua natural. El consumo de alimentos entre ambos grupos y los marcadores bioquímicos se analizaron al final del tratamiento. Las concentraciones séricas de glucosa, lípidos, proteínas totales, albúmina, creatinina y hemoglobina se midieron mediante espectroscopia. Los resultados mostraron que el grupo de ratas que consumieron agua endulzada con sacarosa ingirieron menos alimento balanceado; consumieron una mayor cantidad de líquidos y calorías. Sin embargo, el consumo de agua endulzada no modificó el perfil lipídico. Los resultados de marcadores nutricionales tales como peso, creatinina, proteínas totales, albúmina y hemoglobina mostraron que el consumo crónico de sacarosa al 12% no ocasionaba un estado de desnutrición a largo plazo por menor consumo de alimento balanceado.
Abstract The relationship between the consumption of sucrose-sweetened beverages and the reduction in the intake of foods has been the subject of study in the field of public health and nutrition. As consumption of these beverages has increased in recent decades, an increase in diet-related health problems has been observed. In the present work, the effect of chronic intake of water sweetened with 12% sucrose on balanced food consumption, lipid profile, insulin resistance, as well as on some markers of nutritional status such as weight, total serum, protein, albumin, hemoglobin and creatinine in male Wistar rats is analysed. Water sweetened with sucrose was administered to a group of 9 rats for 8 weeks, with a group of 9 rats that drank natural water as a control. Food consumption between both groups, as well as blood chemistry markers, were analysed at the end of treatment. Serum concentrations of glucose, lipids, total protein, albumin, creatinine, and hemoglobin were measured by spectroscopy. The results showed that the group of rats that consumed water sweetened with sucrose ingested less balanced food; they consumed a greater amount of fluids and calories. However, consumption of sweetened water did not modify the lipid profile. The results of nutritional markers such as weight, creatinine, total protein, albumin and hemoglobin show that chronic consumption of 12% sucrose does not cause a state of long-term malnutrition due to lower consumption of balanced food.

A síndrome metabólica é caracterizada pela presença concomitante de alteração na glicemia, dislipidemia, elevação da pressão arterial e adiposidade excessiva, os quais elevam o risco cardiovascular. O objetivo deste trabalho foi analisar os parâmetros da síndrome metabólica e a associação com o consumo de alimentos ultraprocessados e bebidas adoçadas em adolescentes com excesso de peso. Realizou-se um estudo transversal, conduzido com 67 adolescentes com excesso de peso, de um ambulatório pediátrico de um hospital público no município de São Paulo. A avaliação antropométrica consistiu na aferição de peso, estatura e circunferência da cintura. Foram coletados dados de glicose, triglicérides, HDL-c, e pressão arterial, e a síndrome metabólica (SM) analisada de acordo com critérios da Associação Brasileira de Nutrologia. O consumo alimentar foi avaliado pelo questionário de frequência alimentar semiquantitativo. A prevalência de síndrome metabólica foi de 56,7%. Os parâmetros mais prevalentes foram redução de HDL-c (71,6%), elevação da pressão arterial sistólica (70,1%) e da glicemia de jejum (64,2%). Observou-se correlação positiva entre a glicemia de jejum e o consumo de alimentos ultra processados e bebidas adoçadas.
Metabolic syndrome is characterized by the concomitant presence of changes in blood glucose, dyslipidemia, elevated blood pressure and excessive adiposity, which increase cardiovascular risk. The objective of this study was to analyze the parameters of metabolic syndrome and the association with the consumption of ultra-processed foods and sweetened beverages in overweight adolescents. A cross-sectional study was carried out with 67 overweight adolescents from a pediatric outpatient clinic of a public hospital in the city of São Paulo. The anthropometric assessment consisted of measuring weight, height and waist circumference. Data on glucose, triglycerides, HDL-c, and blood pressure were collected, and metabolic syndrome (MS) was analyzed according to criteria from the Brazilian Association of Nutrology. Food consumption was assessed using the semi-quantitative food frequency questionnaire. The prevalence of metabolic syndrome was 56.7%. The most prevalent parameters were a reduction in HDL-c (71.6%), and an increase in systolic blood pressure (70.1%) and fasting blood glucose (64.2%). Blood glucose was positively associated with the sweetened beverage consumption score and BMI. It is concluded that there is a high prevalence of metabolic syndrome in adolescents, with glycemia being associated with the consumption of sweetened beverages.

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.

Background: Foot ulcers are considered as a serious complication, especially for patients with diabetes. People with diabetes and people with peripheral vascular disease are more likely to develop foot ulcers. If an infection occurs in an ulcer and is not treated in the proper way, it can develop into cellulitis, osteomyelitis, or gangrene that may require some part of the toe, foot, or lower leg to be amputated. The aim of this study was to find the socio-demographic, clinical, and diabetes status of foot ulcer patients. Material & Methods: This prospective observational study was conducted in the Department of Surgery, Rajshahi Medical College Hospital, Rajshahi, Bangladesh, during the period from March 2012 to August 2012. In total 100 patients with foot ulcers in the different surgical units of the mentioned hospital were enrolled in this study as study subjects. Data from the study regarding age, sex, occupation, smoking habit, and socio-demographic condition were recorded in the prescribed questionnaire. The purposive sampling technique was used for this study. All data were processed, analyzed, and disseminated using MS Excel and SPSS version 23 programs as necessary. Results: In this study, the male-female ratio of the participants was 2:1. The maximum number of patients (42%) were from the age of 51-60 years and the highest number of patients were housewives (28%), followed by farmers (22%). Among the total male patients, 87.88% were smokers. Low HDL was found in 51% of patients and 68% of patients had been suffering from diabetes mellitus,18% from Buerger’s disease and 6% from atherosclerosis, and 8% from malignant foot ulcer. Most of the diabetic patients (95.59%) were hyperglycemic on admission and 55.88% had diabetes for 6-10 years. On admission, 3 patients (4.41%) had controlled blood sugar and 65 patients (95.59%) had uncontrolled blood sugar. Conclusion: The frequency of foot ulcers among the male population was higher than that in females. Concerning occupation of the patients, housewives and farmers were the most prevalent. Smokers were most affected groups among the study population. Pre-diagnosed diabetes mellitus for a long period was one of the major clinical issues in most of the patients. Uncontrolled blood sugar was also seen in majority of the patients regarding clinical background.

Introduction: The school population represents a fundamental group for health promotion actions, given that the foundations of healthy behaviors in adult life are established in children and adolescents, who can be greatly influenced by the school. Objective: To describe the health-related behavioral factors of schoolchildren between 13 and 17 years of age in secondary and middle school in Colombia. Methods: A national cross-sectional study was conducted (i.e., School Health Survey -ENSE-) that recorded information on dietary practices, physical activity, alcohol and drug consumption, injuries and bullying, and oral, visual and hearing health. Sampling was probabilistic, cluster and multistage. Results: Schoolchildren have low consumption of fruits, vegetables (13.1%) and dairy (76.5 %), high consumption of ultra-processed foods (82.4 %), sugary drinks (74.0 %) and fast foods (14.8 %), frequent addition of salt at the table (43.3 %), low compliance with physical activity recommendations (15.0 %) and high sedentary lifestyle (46.3 %), frequent consumption of alcohol (44.7 %) and psychoactive substances (14.7 %), in addition to prevalent situations of bullying (15.4 %), rejection (8.2 %) and verbal aggression (42.7 %). Conclusions: The ENSE shows critical inequalities by gender, ethnicity and social class, throughout the country. The indicators observed in schoolchildren are precursors of various chronic and degenerative diseases and mental illness, which requires the urgent attention of the different social actors in the country.

Resumo A alimentação adequada tem profundo impacto na saúde dos idosos, e uma especial atenção deve ser dada ao consumo de açúcares de adição na dieta, que em excesso está associado a pior controle das doenças crônicas nesta fase. O objetivo do estudo foi avaliar a prevalência do consumo de açúcares de adição de idosos da região de Campinas-SP, seus fatores associados e suas principais fontes alimentares. Trata-se de estudo transversal realizado na região de Campinas-SP, com amostra de conveniência de 586 idosos. O consumo foi obtido por meio de dois recordatórios de 24 horas, sendo inadequado se >5% do consumo energético total. Também foi calculada a contribuição dos alimentos em relação ao teor total de açúcares. Considerou-se nível crítico de p<0,05. O consumo médio de açúcares de adição estava acima do recomendado (7,0%), inadequado em mais da metade da população estudada, sendo o açúcar de mesa e o mel as principais fontes dietéticas. A prevalência de inadequação do consumo foi maior entre mulheres (69,8%; p=0,004) e em indivíduos com baixo peso (83,7%; p=0,014), e o consumo foi menor em portadores de diabetes (47,8%; p<0,001). Os resultados apontam para que sejam elaboradas ações de saúde e nutrição a fim de garantir um consumo adequado de açúcares nesta fase.
Abstract Adequate nutrition has a profound impact on older adults' health. Therefore, special attention should be given to the dietetic intake of added sugars, which in excess is associated with poorer control of chronic diseases in this phase. The aim of the study was to evaluate the prevalence of consumption of added sugars in older adults in the Campinas-SP region, its associated factors, and its main dietary sources. A cross-sectional study was conducted in the region of Campinas-SP, with a convenience sample of 586 older individuals. Intake was obtained using two 24-hour food recalls, and values >5% of total energy consumption were considered inadequate. The contribution of the groups and foods in relation to the total content of sugars was also calculated. A critical level of p<0.05 was considered. The average intake of added sugars was higher than recommended (7.0%), and this inadequacy was observed in more than half of the sample, being table sugar and honey the main dietary sources. The prevalence of inadequate consumption was higher among women (69.8%; p=0.004) and individuals with low weight (83.7%; p=0.014), and lower in those with diabetes (47.8%; p<0.001). Results indicate that health and nutrition actions should be developed to ensure adequate sugar intake at this stage.

Hemoglobin and glycosylated hemoglobin (HbA1C) are frequently monitored health indicators in population based studies for information about the status of nutrition and diabetes control. We present here possibly for the first time the findings of simultaneous estimation of Hemoglobin and HbA1C on Dried blood spot (DBS) samples by a single test. Validation was done by turbidimetric inhibition immunoassay (TINIA) using Roche Integra 400 plus instrument. Paired whole blood and DBS samples were tested for HbA1C estimation by Integra 400 plus. Total hemoglobin values obtained during HbA1C estimation were compared with hemoglobin values estimated by Coulter AcT 5 Diff CP Hematology counter. Agreement in HbA1C and hemoglobin values between paired whole blood and DBS samples was found to be high with R2 values of 0.994 and 0.9349, respectively. Intra- and inter- assay precision was found to be within 10% for both parameters. Values obtained after assaying DBS samples prepared by spotting proficiency samples on Whatman 903 protein saver cards demonstrated acceptable standard deviation indices resulting in successful participation in EQAS programs for both these parameters. The results reveal the potential of TINIA for simultaneous estimation of hemoglobin and HbA1C from a single punch of the DBS samples.

Con el objetivo de priorizar políticas públicas para disminuir el consumo de bebidas azucaradas en Argentina, Brasil, El Salvador y Trinidad y Tobago e identificar las necesidades de información relacionadas con la carga de enfermedad atribuible a su consumo se realizó un diálogo de políticas en el que participaron miembros de gobierno, organizaciones de la sociedad civil, investigadores y comunicadores de países de Latinoamérica y el Caribe. Se llevaron a cabo exposiciones y talleres deliberativos utilizándose herramientas de recolección de datos semiestructuradas y discusiones grupales facilitadas. Las intervenciones priorizadas fueron el incremento de impuestos, el etiquetado frontal, la restricción de la publicidad, promoción y patrocinio y las modificaciones del entorno escolar. La principal barrera percibida fue la interferencia de la industria alimentaria. La realización de este diálogo de decisores permitió la identificación de las políticas públicas prioritarias para disminuir el consumo de bebidas azucaradas en la región.
In order to prioritize public policies to reduce the consumption of sugar-sweetened beverages in Argentina, Brazil, El Salvador and Trinidad and Tobago and to identify information gaps related to the burden of disease attributable to their consumption, a policy dialogue was held with government members, civil society organizations, researchers and communicators from Latin American and Caribbean countries. Presentations and deliberative workshops were conducted using semi-structured data collection tools and group discussions. The prioritized interventions were tax increases, front labeling, restriction of advertising, promotion and sponsorship, and modifications regarding the school environment. The main perceived barrier was the interference from the food industry. This dialogue among decision-makers led to the identification of priority public policies to reduce the consumption of sugar-sweetened beverages in the region.

Resumo Objetivou-se avaliar o impacto do consumo de sucos antes dos 6 meses de idade no Índice de Massa Corporal para Idade (IMC/I) e no consumo alimentar em pré-escolares. Estudo longitudinal com amostra composta por mães e seus filhos (n=103) entre 6 meses e 3 a 6 anos. Peso e estatura foram aferidos e convertidos para o escore z de IMC/I. Para avaliar o consumo alimentar, foi utilizado o Questionário de Frequência Alimentar Infantil. Testes de Qui-Quadrado e t de Student foram utilizados para comparação entre os grupos. Não houve diferença nos parâmetros antropométricos entre pré-escolares que receberam ou não suco antes dos seis meses. Aquelas que tiveram introdução de suco mais precoce (≤150 dias de vida) apresentaram consumo mais frequente (≥1x/dia) de suco artificial (63,8% versus 35,7%; p=0,028) e biscoito recheado (21,3% versus 14,3%; p=0,001) na idade pré-escolar. Crianças que receberam suco do tipo artificial antes dos 6 meses tiveram maior prevalência de consumo de refrigerante entre 1 e 4x/semana (69,2% versus 27,4%; p=0,014) e menor prevalência de consumo de achocolatado pelo menos 1x/dia (38,5% versus 69,4%; p=0,027). Sendo assim, crianças com introdução precoce de suco apresentaram maior consumo de alimentos doces e bebidas açucaradas em fase pré-escolar.
Abstract The aim of this study was to evaluate the impact of fruit juice consumption before 6 months of age on Body Mass Index-for-age (BMI-for-age) and food consumption in preschoolers. We conducted a longitudinal study with mothers and their children (n=103) at 6 months and 3-6 years. Weight and height were measured and converted into BMI-for-age z-scores. Food consumption was analyzed using the Food Frequency Questionnaire for Children. Groups were compared using the chi-squared and Student's t-tests. No differences in anthropometric measurements were found at preschool age between children who had been given fruit juice before 6 months and those who had not. Consumption of artificial juice (≥once/day) and sandwich cookies at preschool age was higher in children with early introduction of fruit juice (≤150 days of life) (63.8% versus 35.7%; p=0.028 and 21.3% versus 14.3%; p=0.001, respectively). The prevalence of the consumption of soda (1 to 4 times/week) and chocolate milk (at least once/day) was higher in children who had been given artificial juice before 6 months (69.2% versus 27.4%; p=0.014 and 38.5% versus 69.4%; p=0.027, respectively). It can be concluded that the consumption of sweet foods and sugary beverages was higher in children with early introduction of fruit juice.

ObjectiveThe therapeutic effect of polysaccharides from Zanthoxyli Pericarpium on Alzheimer's disease（AD） was evaluated through establishing a mouse model of AD， and the structural characteristics of the polysaccharides was analyzed by sugar spectrum. MethodThe AD model of mice with rapid aging was established by intraperitoneal injection of D-galactose combined with gavage of aluminum trichloride， and the learning and memory ability of mice was evaluated by Morris water maze test， the histopathological status of brain and neuronal damage were observed by hematoxylin-eosin（HE） staining and Nissl staining. After hydrolysis of polysaccharides from Zanthoxyli Pericarpium with acid and different glycosidases， the characteristics of hydrolysates were analyzed by high performance thin layer chromatography（HPTLC） and fluorescence assisted carbohydrate gel electrophoresis（PACE）. HPTLC chromatography was performed on a silica gel 60 plate with sampling volume of 5 μL， developing solvent of ethyl acetate-glacial acetic acid-water（2∶2∶1）， developing twice， aniline-diphenylamine-phosphoric acid solution as chromogenic agent， and heating at 105 ℃ for 10 min， and then observed under sunlight. PACE experimental conditions were 34% separation gel and 8% concentration gel， electrophoresis buffer was 0.1 mol·L-1 tris（hydroxymethyl） aminomethane（Tris）-boric acid buffer（pH 8.2）. Electrophoresis was carried out at 0 ℃ and the loading amount was 3-6 μL. The sample ran to the front of the gel with a constant current of 15 mA， and imaged under ultraviolet 365 nm. ResultThe results of Morris water maze test showed that polysaccharides from Zanthoxyli Pericarpium significantly improved the learning and memory ability of AD model mice， shortened the escape latency， and significantly increased the number of crossing and the residence time in the target quadrant. The results of histopathological experiments showed that polysaccharides from Zanthoxyli Pericarpium could improve the pathological conditions and neuronal damage in the CA1 and CA3 regions of hippocampus of AD mice， and the number of Nissl corpuscles was significantly increased. The results of sugar spectrum analysis showed that the results of HPTLC and PACE analysis were basically consistent， polysaccharides from Zanthoxyli Pericarpium could be mainly hydrolyzed into small molecular sugars by cellulase and pectinase， indicating that they mainly contained β-1，4-glucosidic bond and α-1，4-galacturonic acid glycosidic bond， and could be slightly hydrolyzed by glucanase， β-galactosidase and β-mannase， indicating that they contained only a small amount of α-1，6-glucosidic bond， β-galactosidic bond， β-1，4-mannosidic bond. ConclusionPolysaccharides from Zanthoxyli Pericarpium has obvious therapeutic effect on AD mice， and its structure mainly contains β-1，4-glucosidic bond and α-1，4-galacturonic acid glycosidic bond， which can provide a reference for the structural analysis of traditional Chinese medicine polysaccharides.
