Seguridad alimentaria, subalimentación y canasta alimentaría en el contexto de las políticas públicas en Venezuela. Período2017-2022 / Food security, undernourishment and food basket in thecontext of public policies in Venezuela. Period 2017-2022

El presente estudio tiene como objetivo analizarla relación entre los indicadores de seguridad alimentaria,subalimentación y costo de la canasta alimentaria en el contextode las políticas públicas en materia alimentaria en Venezuela,durante el periodo comprendido entre 2017 y 2022. Para ello, sellevó a cabo un análisis exhaustivo de los datos disponibles sobrela seguridad alimentaria en Venezuela, incluyendo informaciónsobre la subalimentación, y el costo de la canasta alimentaria.Asimismo, se analizaron las políticas públicas implementadas enel país en materia alimentaria durante el periodo de estudio, conel fin de entender su impacto en los indicadores de seguridadalimentaria. Ninguna de las asociaciones estudiadas resultó sersignificativa a nivel estadístico (p>0,05), por lo que, aunqueteóricamente existe una relación entre estos indicadores en elperíodo estudiado, el carácter multidimensional prevalece y hacecompleja la posibilidad de comparaciones. Se identificaron laspolíticas públicas que requieren mejoras o ajustes para proteger laseguridad alimentaria del venezolano. Estos resultados obtenidospodrán ser de utilidad para los responsables de la toma dedecisiones en el país, así como para los investigadores yprofesionales interesados en el tema de la seguridad alimentariay la nutrición

EL objective of this study is to analyzethe relationship between the indicators of food security,undernourishment and the cost of the food basket in thecontext of public policies on food in Venezuela, during theperiod between 2017 and 2022. For this, an exhaustive analysisof the available data on food security in Venezuela wascarried out, including information on undernourishment, andthe cost of the food basket. Likewise, the public policiesimplemented in the country regarding food during the studyperiod were analyzed, in order to understand their impacton food security indicators. None of the associations studiedturned out to be statistically significant (p>0.05), therefore,although theoretically there is a relationship between theseindicators in the period studied, the multidimensional natureprevails and makes comparability complex. Public policies that require improvements or adjustments to protect Venezuelanfood security were identified. These results obtained may beuseful for those responsible for decision-making in the country,as well as for researchers and professionals interested in thesubject of food security and nutrition.

Canasta alimentaria normativa: perspectivas actuales e implicaciones para la salud pública en Venezuela / Normative Food Basket current perspectives and implications for public health in Venezuela

La Canasta Alimentaria Normativa (CAN) es un instrumento estratégico de planificación y seguimiento, que impacta el ámbito económico (fijación del salario mínimo SM y del umbral de la pobreza relativa), la seguridad alimentaria y la salud pública. El objetivo fue describir la evolución histórica de la CAN en Venezuela, contrastando su valoración económica respecto al SM durante el período 1990 ­ 2023. Tipo de estudio: Descriptivo. Se empleó la CAN del Instituto Nacional de Estadísticas/Instituto Nacional de Nutrición (INE/INN) y su comparación con la canasta del Centro de Documentación y Análisis Social de la Federación Venezolana de Maestros(CENDAS ­ FVM). Los valores mensuales de la CAN y del SM se recalcularon a dólares USA, de acuerdo a la tasa de cambio oficial. No se incluyó evaluación de la estructura interna, ni sus expresiones en términos de aporte de energía y nutrientes. Resultados: Desde 1990 hasta el año 2015, se requirieron entre1,0 y 1,8 SM y entre 0,6 y 1,7 Ingresos Mínimos Legales (IML)para acceder a la CAN. Para el año 2023 se requirieron hasta 78,3SM y 51,6 IML. El valor promedio de la canasta del CENDAS-FVM fue superior al valor de la CAN INE/INN, en una proporción de 1,7: 1. Conclusiones: la CAN resultó sensible en identificar los cambios y tendencias de su estimación económica, en el ambiente inflacionario venezolano. El uso de sus resultados está sujeta a cierto grado de discrecionalidad política. El costo de la CAN, expresa una contracción del poder de compra de los hogares venezolanos con potenciales impactos sobre la nutrición y la salud física y mental a corto y largo plazo.

The Normative Food Basket (NFB) represents astrategic planning and monitoring instrument, which impactsthe economic sphere (setting of the minimum wage (MW) andthe relative poverty threshold), food security and public health.The objective was to describe the historical evolution of the NFB in Venezuela, contrasting its economic valuation with respect to the MW during the period 1990 ­ 2023. Type of study: Descriptive. The NFB of the National Institute of Statistics/National Institute of Nutrition (NIS/NIN) was used and itscomparison with the basket of the Center for Documentationand Social Analysis of the Venezuelan Federation of Teachers (CENDAS ­ FVM). The monthly values of the NFB and theMW were recalculated into dollars (US$), according to theofficial exchange rate. No evaluation of the internal structurewas included, nor its expressions in terms of energy and nutrientcontribution. Results: From 1990 to 2015, between 1.0 and1.8 MW and between 0.6 and 1.7 Minimum Legal Income(MLI) were required to access the NFB. By 2023, up to 78.3MW and 51.6 MLI were required. The average value of the CENDAS-FVM basket was higher than the value of the NFBNIS/NIN, in a proportion of 1.7: 1. Conclusions: As a statistical operation, the NFB was sensitive in identifying changes andtrends in its estimate economic, in the Venezuelan inflationaryenvironment. The use of its results is subject to a certain degree ofpolitical discretion. The cost of CAN expresses a contraction inthe purchasing power of Venezuelan households with potentialimpacts on nutrition and physical/mental health in the shortand long term.

New strategies for the treatment of carcinoma of unknown primary / 中华肿瘤杂志

Carcinoma of unknown primary (CUP) is a kind of metastatic tumor whose primary origin cannot be identified after adequate examination and evaluation. The main treatment modality of CUP is empiric chemotherapy, and the median overall survival time is less than 1 year. Compared with immunohistochemistry, novel method based on gene expression profiling have improved the sensitivity and specificity of CUP detection, but its guiding value for treatment is still controversial. The approval of immune checkpoint inhibitors and pan-cancer antitumor agents has improved the prognosis of patients with CUP, and targeted therapy and immunotherapy based on specific molecular characteristics are the main directions of future research. Given the high heterogeneity and unique clinicopathological characteristics of CUP, "basket trial" is more suitable for clinical trial design in CUP.

Evaluation of a newly designed basket in non-radiation endoscopic lithotomy for common bile duct stones (with video) / 中华消化内镜杂志

Objective:To evaluate a newly designed basket fit for digital cholangioscope in non-radiation endoscopic lithotomy for common bile duct stones.Methods:Seventy-eight patients who underwent non-radiation endoscopic removal of common bile duct stones at Zhongda Hospital Southeast University between February and October 2021 were enrolled in the randomized controlled trial, and were randomly assigned into the new basket group ( n=35) and the conventional basket group ( n=43) by drawing lots. Procedures of cholangioscope-based biliary exploration and stone removal by baskets, volume of water irrigation, time lengths of biliary exploration, stone removal and whole endoscopic procedure, and adverse events were compared. Results:Compared with the conventional basket group, the new basket group needed less biliary explorations (1.08±0.28 VS 2.30±0.51, t=-12.535, P<0.001), smaller volume of water irrigation (46.14±11.89 mL VS 78.62±10.09 mL, t=-13.052, P<0.001), and shorter time of biliary exploration and stone removal (9.69±2.97 min VS 12.67±2.51 min, t=-4.815, P<0.001) and whole endoscopic procedure (30.17±7.19 min VS 33.44±6.69 min, t=-2.076, P=0.041). The incidence of adverse events was not significantly different between the two groups [5.7% (2/35) VS 11.6% (5/43), χ2=0.826, P=0.363]. Conclusion:This newly designed basket can facilitate digital cholangioscope-guided non-radiation endoscopic removal of common bile duct stones with the advantages of shorter operation time, less exploration time of choledochoscopy and smaller volume of water irrigation.

Análisis de la distribución de macronutrientes en canastas alimentarias entregadas por las municipalidades durante la pandemia de COVID-19 en Perú / Analysis of the distribution of macronutrients of food baskets delivered by municipalities during the COVID-19 pandemic in Peru

RESUMEN Objetivos. Evaluar y comparar la distribución de macronutrientes de las canastas alimentarias entregadas por las municipalidades peruanas durante la pandemia de COVID-19 según dominio geográfico y nivel de presupuesto asignado. Materiales y métodos. Análisis secundario de la base de datos «Consulta de adquisición y distribución de bienes de primera necesidad de la canasta básica familiar¼ de la Contraloría General de la República. Se realizó un muestreo probabilístico estratificado. Se calculó la distribución del aporte calórico según macronutrientes y se comparó con los intervalos aceptables de distribución de macronutrientes (IADM) del Instituto de Nutrición de Centro América y Panamá (INCAP) y del Instituto Nacional de Defensa Civil (INDECI). Resultados. A nivel nacional la mediana del aporte calórico de las proteínas fue 7,7%; carbohidratos 62,5%, y grasas 28,1%. La proporción de municipalidades con canastas con déficit de proteínas fue de 84%. Las municipalidades con canastas con exceso de carbohidratos variaron de 16,5% (según INCAP) a 35,9% (según INDECI) y con exceso de grasas fue 61,6 % (según INCAP) y 20,2% (según INDECI). Según INDECI, a nivel nacional solo el 9,2% de municipalidades entregaron canastas con distribución adecuada de macronutrientes, aquí destaca Lima Metropolitana con las proporciones más altas; mientras que en la selva este porcentaje fue menor del 5%. Conclusiones. La mayoría de las canastas entregadas no tuvieron distribución adecuada de macronutrientes, en especial las canastas de municipalidades fuera de Lima Metropolitana o las que contaban con menor presupuesto. Los carbohidratos y las grasas fueron los nutrientes que se incluyeron en exceso, mientras que las proteínas tuvieron déficit.

ABSTRACT Objectives. To evaluate and compare the macronutrient distribution of the food baskets delivered by Peruvian municipalities during the COVID-19 pandemic according to the geographic domain and assigned budget level. Materials and methods. Secondary analysis of the database "Consultation of Acquisition and distribution of basic necessities of the basic family basket" of the General Comptroller of the Republic. Stratified probability sampling was carried out. The caloric intake distribution was calculated according to macronutrients and compared with the Acceptable Intervals of Macronutrient Distribution (IADM) of the Nutrition Institute of Central America and Panama (INCAP) and the National Institute of Civil Defense (INDECI). Results. At the national level, the median caloric intake of proteins was 7.7%; for carbohydrates it was 62.5%; and for fats it was 28.1%. The proportion of municipalities with protein deficit was 84%; Municipalities with excess carbohydrates ranged from 16.5% (according to INCAP) to 35.9% (according to INDECI), and with excess fat, it was between 61.6% (according to INCAP) and 20.2% (according to INDECI). According to INDECI, nationally only 9.2% of municipalities delivered baskets with an adequate distribution of macronutrients; Metropolitan Lima stands out with the highest proportions of adequate baskets, while in the Jungle region this percentage was less than 5%. Conclusions. Most of the baskets delivered did not have adequate macronutrient distribution. Especially the baskets of municipalities outside of Metropolitan Lima or those that had smaller budget. Carbohydrates and fats were the nutrients that were included in excess, while proteins were deficient.

Application of the in-basket test in head nurse competence evaluation / 中华医院管理杂志

Objective:To evaluate the competence of head nurses by using the in-basket test for establishing a hierarchical training system for these nurses.Methods:A set of in-basket test was independently designed to evaluate the head nurses of a tertiary hospital in September 2021.Fourteen competency indicators, including positive initiative, coordination and communication ability, and leadership, problem solving ability, motivation, empowerment, attention to quality and order, etc, were selected to analyze the answers of the in-basket test and score their competency level. The measures were described by Mean±SD and M(IQR), and the counts were described by rates and percentages. The rank sum test and multiple linear regression were used to analyze the influencing factors of competency scoring of head nurses. Results:A total of 133 head nurses were tested, with a total competency scoring of 30.0(5.5). The highest indicators were talent cultivation 3.0(2.0), positive initiative 3.0(1.0), coordination and communication ability 3.0(1.0), while those with lower scores were empowerment 1.0(1.0) and motivation 1.5(1.5). The rank sum test analysis showed that age, position, job position character and working seniority were the influencing factors of competency score( P<0.05). The multiple linear regression analysis showed that, working seniorities of 16-20 years( β=0.583, P=0.013), 21-25 years( β=0.732, P=0.008), 26-30 years( β=0.632, P=0.026) were the influencing factors of competency score of head nurses. Conclusions:The in-basket test is practical to evaluate the competence of head nurses as a basis for their targeted training in the future.

Application of umbrella design and basket design in evidence-based research for traditional Chinese medicine / 中国中药杂志

This paper introduced the basic definition, application scope, advantages and challenges of the master protocol, basket design, umbrella design and platform trial, and put forward the idea of using master protocol, basket design and umbrella design in Chinese medicine(CM) by considering the characteristics of CM and research experiences. The author pointed out that master protocol, basket design and umbrella design, as a high-efficiency research and design strategy, can be used in the clinical research on the treatment of the same disease with different therapies, the treatment of different diseases with the same therapy and the combination of diseases and CM syndromes. In particular, the exploration from the classification of CM syndromes can supplement the gaps in the cli-nical research on CM syndromes. In the application of such designs, it is also necessary to pay attention to their potential challenges and develop reasonable and feasible plans on research implementation, management and statistical analysis in advance to meet these challenges.

Análisis de la canasta básica alimentaria de Costa Rica: oportunidades desde la alimentación y nutrición / Analysis of the Costa Rican Basic Food Basket: Opportunities for improving Feeding and Nutrition

Resumen: Introducción: La canasta básica alimentaria (CBA) es un conjunto de alimentos y bebidas, que se elabora a partir del consumo reportado por los costarricenses y considera tres criterios fundamentales: universalidad, aporte energético y porcentaje del gasto. Objetivo: Identificar la congruencia de la estructura de la CBA actual, con el derecho humano a la alimentación de la población costarricense. Metodología: A partir de la estructura de la CBA urbana actual, se compararon las cantidades de alimentos allí sugeridas con las recomendaciones de las Guías Alimentarias para Costa Rica. Se comparó el perfil de energía y nutrientes contra las recomendaciones dietéticas diarias. Se realizó una recreación de las cantidades de alimentos de la CBA para un día. Se realizaron modificaciones para una CBA sugerida con un mejor perfil nutricional y se costeó para comparar el costo de la CBA sugerida con la CBA actual. Resultados y discusión: Se incorporan en la CBA sugerida 21 alimentos, se eliminan seis, se aumenta la cantidad sugerida de dos y se disminuye la cantidad sugerida de uno. Se logra con ello aumentar el aporte de fibra dietética, calcio, magnesio, potasio, zinc, vitaminas C, E y K y reducir la cantidad de azúcar total, azúcar agregada, sodio y colesterol. Con estos cambios, el costo de la CBA sugerida se reduce ligeramente Conclusiones: Se necesita contemplar en la CBA otros aspectos nutricionales, además del aporte energético de los alimentos, como el aporte de los micronutrientes, los cuales son esenciales para la prevención y el tratamiento de enfermedades crónico-degenerativas, que son uno de los principales problemas de salud que aqueja la población en la actualidad. Por lo tanto, la CBA debe ser replanteada para ofrecer un mínimo alimentario congruente, de manera que se estimule y favorezca una alimentación balanceada, variada y adecuada para las necesidades nutricionales de la población en Costa Rica

Abstract: Introduction: The Basic Food Basket (CBA) consists of a list of foods and beverages that represent current food habits in Costa Rica. Criteria for including an item in the CBA are universality, energy and protein contribution and percentage of total expenditure on food. The objective of this study is to demonstrate that the inclusion of nutritional criteria can improve the structure of the current CBA, without increasing cost and contribute to a greater congruence with the human right to food. Methodology: The quantities of foods included in the current urban CBA were compared with the Food Guideline recommendations and the nutritional content of foods in the CBA was compared with the daily nutrient recommendations. Suggested modifications were made so that the CBA has a better nutritional profile and its cost calculated to see the impact at the economic level. A recreation of the amounts of CBA food for one day was performed. Results and discussion: 21 additional foods were incorporated into the suggested CBA, six were eliminated, two foods were increased in quantity and in one quantity was decreased. It is possible to increase the contribution of dietary fiber, calcium, magnesium, potassium, zinc, vitamins C, E and K and reduce the contribution of total sugar, added sugar, sodium and cholesterol without increasing cost; in fact the cost of the modified CBA is slightly reduced. Conclusions: It is possible to include additional nutritional criteria such as micronutrient content in the formulation of the CBA without increasing cost. The structure of the CBA should be reviewed to offer a more adequate, balanced, and varied diet that responds to the current nutritional needs of the population in Costa Rica.

Avaliação dos indicadores de aquisição, disponibilidade e adequação nutricional da cesta básica de alimentos brasileira / Assessment of the indicators of purchasing, availability, and nutritional adequacy of the Brazilian basic food basket

Resumo O objetivo deste estudo foi avaliar a evolução dos custos para aquisição da cesta básica associados ao poder aquisitivo do salário mínimo, além de mensurar a disponibilidade per capita nos domicílios brasileiros dos alimentos que compõem a cesta básica. Também foram avaliadas a adequação da composição nutricional e a qualidade da dieta baseada no consumo diário de itens da cesta básica. Os resultados obtidos apontam a existência de períodos de elevação de preços para aquisição dos itens da cesta básica, assim como a incapacidade do salário mínimo para o custeio para tais provisões alimentares. Foi verificado que as dietas baseadas no consumo dos itens da cesta básica apresentam quantidade de energia e sódio superiores às recomendações para indivíduos adultos, além de apresentar quantidades insuficientes de cálcio, potássio e vitamina A. A avaliação da qualidade das dietas apontou baixa quantidade de frutas, vegetais, cereais na dieta composta pelos itens das cestas básicas, sendo constatado excesso energético proveniente de gorduras e açúcar de adição. Diante de tais evidências, recomenda-se revisão da composição das cestas básicas para atendimento de requisitos nutricionais básicos em alimentação para população brasileira.

Abstract The scope of this study was to assess the evolution of costs for purchasing the basic food basket associated with the purchasing power of the minimum wage, besides measuring the availability per capita in Brazilian households of the items comprised in the food basket. Additionally, adequacy of the nutritional composition and diet quality based on daily consumption of food basket items was evaluated. The results obtained indicate the existence of periods of price increase for the acquisition of the food basket items, as well as the inability of the minimum wage to meet the cost of such food supplies. It was verified that the diets based on the consumption of food basket items have a higher calorie and sodium content than the recommendations for adults, as well as insufficient amounts of calcium, potassium, and vitamin A. The evaluation of the quality of the diets indicated low amounts of fruit, vegetables, cereals in the diet consisting of the items of the food baskets, with excess calories from fats and added sugar being verified. In view of such evidence, a review of the composition of the food baskets is recommended in order to meet basic nutritional requirements in food for the Brazilian population.

Análisis del costo diferencial entre la alimentación apta celíaca y no celíaca / Analysis of the differential cost between celiac and non-celiac apt food

Introducción: la población argentina exhibe una elevada prevalencia de enfermedad celíaca (1/100) y la alimentación es su único tratamiento, por ende, el costo de la dieta es un factor clave para la adherencia. Objetivos: calcular el costo diferencial de la dieta de una mujer adulta celíaca vs. no celíaca basado en la Canasta Básica de Alimentos (CBA) y en el patrón alimentario propuesto por las Guías Alimentarias para la Población Argentina (GAPA). Estimar la proporción que representa en base al Salario Mínimo Vital y Móvil (SMVM) en ambos casos. Materiales y método: se tomaron alimentos trazadores extraídos de la plataforma digital de un hipermercado durante el mes de septiembre y diciembre del 2018 para realizar los cálculos de costo de la dieta, considerando los alimentos de más bajo precio. Resultados: el costo de la alimentación propuesta por las GAPA arrojó una diferencia de un 55,27% superior para la población celíaca (+ $1410,08) para septiembre y de un 48,60% (+ $1537,63) para el mes de diciembre. El costo mensual representó un incremento de 13,18% del SMVM para septiembre y de 13,61% para diciembre para la población celíaca. Tomando la CBA, el costo diferencial de la dieta mensual fue mayor (89,27% más cara, equivalente a 1182,76 pesos más) para el mes de septiembre, y 46,81% que equivalen a $886,10 para diciembre. Representó un incremento de 11,06% del SMVM para septiembre y de 7,84% para diciembre. Conclusiones: la alimentación para una mujer adulta celíaca representa un costo mayor que para una mujer adulta no celíaca en la CABA. Este es uno de los factores que contribuye a la no adherencia al tratamiento de la enfermedad, siendo la alimentación la única estrategia para tratarla(AU).

Introduction: Argentinian population exhibits a high prevalence of celiac disease (1/100) and feeding is the only treatment; therefore, the cost of diet is a key factor for adherence. Objectives: to calculate the differential cost of the diet of an adult celiac woman vs. non-celiac one, based on the Basic Food Basket (BFB) and on the dietary pattern proposed by the Dietary Guidelines for the Argentine Population (GAPA). Estimate the proportion that represents based on the Minimum Living Wage (MLW) in both cases. Materials and method: tracers extracted from the digital platform of an hypermarket were taken during September and December 2018 to calculate the cost of the diet, considering the lowest-priced foods. Results: the cost of food proposed by GAPA showed a difference of 55.27% higher for the celiac population ($ 1410.08 more) in September and of 48.60% ($ 1537.63 more) in December. The monthly cost represented an increase of 13.18% for the MLW in September and 13.61% in December for the celiac population. Taking the BFB, the differential cost of the monthly diet was higher (89.27% more expensive, equivalent to 1182.76 pesos more) in September, and 46.81%, equivalent to $ 886.10, in December. It represented an increase of 11.06% for the MLW in September and of 7.84% in December. Conclusions: the food for a celiac adult woman is higher than for a nonceliac adult woman in CABA. This is one of the factors that contributes to non-adherence to the treatment of the disease; food being the only strategy to treat it(AU).

Diseño de una canasta saludable de alimentos y criterios para una evaluación comparativa de precios y densidad de nutrientes / Design of a healthy food basket and criteria for a comparative evaluation of prices and nutrient density

Introducción: asegurar la asequibilidad de la población a una alimentación saludable requiere abordar la conformación y el seguimiento del valor de una canasta saludable de alimentos y de los precios diferenciales de alimentos según calidad nutricional. Objetivos: diseñar una canasta saludable de alimentos (CSA) que resulte consistente con las Guías Alimentarias para la Población Argentina (GAPA). Los objetivos específicos son la definición de un índice de calidad nutricional de alimentos y bebidas, la conformación de la CSA por grupos de alimentos, su valoración económica, y comparar la calidad nutricional y los precios de alimentos disponibles en el mercado. Metodología: el marco metodológico se basó en las GAPA y el concepto de densidad nutricional. Para definir el Índice de densidad nutricional (IDN) de alimentos se consideraron 9 nutrientes esenciales (proteínas, fibra, calcio, hierro, zinc, potasio, Vitaminas A, C y B9), 3 nutrientes críticos (azúcares, sodio y ácidos grasos saturados), el contenido de almidón, y las ingestas recomendadas del Institute of Medicine (IOM). Se elaboraron especificaciones sobre cantidades, variedad y calidades de alimentos para la CSA según grupo de alimentos. Los precios fueron registrados en comercios de la Ciudad y partidos aledaños de Buenos Aires. Resultados: al aplicar el IDN a un conjunto de 320 alimentos y bebidas consumidos por la población argentina, se los clasificó en tres terciles de calidad. El ordenamiento resultante es consistente con las recomendaciones de las GAPA. El valor de la CSA fue de $ 3759.- mensuales (marzo 2018) para la unidad de referencia de 2000 kcal. Al comparar las densidades de nutrientes y precios de los alimentos, hortalizas feculentas, huevo y legumbres son las categorías con mejor relación calidad nutricional/precio. Los alimentos de mejor calidad nutricional tienen un precio de $ 14.- por 100 kcal y los de calidad mínima $ 4,5.- Discusión: la CSA y el IDN son herramientas para orientar y evaluar políticas que promuevan una mejor calidad de dieta.

Introduction: ensuring the population's accessibility to a healthy diet requires addressing the conformation and monitoring of the value of a healthy food basket and the differential prices of foods following nutritional quality. Objectives: to design a healthy food basket (HFB) consistent with the recommendations given by Argentina's dietary guidelines (GAPA). The specific objectives were to define a nutritional quality index for foods and beverages, the composition of HFB by food group, assess values, and compare the prices and nutritional quality of foods available in local markets. Methods: the methodological framework was based on GAPA and the concept of nutritional density. To define the Nutritional Density Index (NDI) of food, 9 essential nutrients (proteins, fiber, calcium, iron, zinc, potassium, Vitamins A, C and B9), 3 critical nutrients (sugars, sodium and saturated fatty acids), the starch content, and the recommended intakes of the Institute of Medicine (IOM) were considered. Specifications were prepared on quantities, variety and qualities of food for the HFB, according to the food group. The prices were registered in shops in the City Centre (CABA) and neighboring municipalities of Buenos Aires. Results: when applying the NDI to a set of 320 foods and beverages consumed by the Argentine population, they were classified into three tertiles of quality. The resulting order is consistent with the recommendations of GAPA. The value of the HFB was $ 3759.- monthly (March 2018) for the reference unit of 2000 kcal. When comparing nutrient densities and food prices, starchy vegetables, eggs and legumes are the categories with the best nutritional quality / price ratio. The foods of better nutritional quality have a price of $ 14.- per 100 kcal and those of minimum quality $ 4.5.- Discussion: the HFB and NDI are tools to guide and evaluate policies that promote a better diet quality.

Effects of Ketamine on Basal Gamma Band Oscillation and Sensory Gating in Prefrontal Cortex of Awake Rats / 神经科学通报·英文版

Gamma band oscillation (GBO) and sensory gating (SG) are associated with many cognitive functions. Ketamine induces deficits of GBO and SG in the prefrontal cortex (PFC). However, the time-courses of the effects of different doses of ketamine on GBO power and SG are poorly understood. Studies have indicated that GBO power and SG have a common substrate for their generation and abnormalities. In this study, we found that (1) ketamine administration increased GBO power in the PFC in rats differently in the low- and high-dose groups; (2) auditory SG was significantly lower than baseline in the 30 mg/kg and 60 mg/kg groups, but not in the 15 mg/kg and 120 mg/kg groups; and (3) changes in SG and basal GBO power were significantly correlated in awake rats. These results indicate a relationship between mechanisms underlying auditory SG and GBO power.

Cesta básica e assistência social: notas de uma antiga relação / The basic food and social assistance: notes from an old relationship

Resumo: Este texto busca refletir sobre o papel que a cesta básica vem cumprindo junto à política de assistência social, uma vez que é prevista a criação de um Sistema Nacional de Segurança Alimentar e Nutricional que reconhece a alimentação como um direito humano fundamental, o que permitiria considerar que a provisão de alimentos, de modo regular e frequente, não seria papel da assistência social, tampouco se configuraria como um dos benefícios eventuais dessa área.

Abstract: This text aims to reflect on the role that the basket has been meeting today with the social welfare policy, since it is envisaged the creation of a National System of Food and Nutritional Security that recognizes food as a fundamental human right, which would allow consider that the provision of food, regular and frequent manner, would not the role of social assistance, nor would be configured as one of the possible benefits of this area.

The total treatment expenses of observation group was signiifcantly fewer than control group (P1.0 cm can efifciently higher the stone removal effects, reduce the stone removal risk and not increase the postoperative complications incidence.

Application of stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi / 中国医师进修杂志

Objective To investigate the application effect of stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi. Methods The clinical data of 96 patients with upper ureteral calculi were retrospectively analyzed, all patients underwent ureteroscopic holmium laser lithotripsy. Forty-eight cases used the stone basket in the operation process (observation group), and 48 cases did not use the stone basket in the operation process (control group). The operation time, length of stay, success rate of lithotripsy, stone residual rate and incidence of postoperative complication were compared between 2 groups. Results The patients of 2 groups successfully completed surgery. There were no statistical differences in operation time, length of stay and incidence of postoperative complication between 2 groups (P>0.05). The success rate of lithotripsy in observation group was significantly higher than that in control group: 97.92% (47/48) vs. 75.00% (36/48), and the stone residual rate was significantly lower than that in control group:4.17%(2/48) vs. 18.75%(9/48), and there were statistical differences (P<0.05). Conclusions The stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi can thoroughly remove stones. It reduces the incidence of residual stones, does not affect the safety of the operation, and has good clinical value.

Factores relacionados con la composición de la canasta básica de alimentos de las familias en la ciudad de La Paz, gestión 2012 / Factors related to the composition of a basic food basket of families in the city of La Paz, term 2012

OBJETIVO: determinar los factores relacionados con la composición de la canasta básica de alimentos de las familias en la ciudad de La Paz. MATERIAL Y MÉTODO: es un estudio analítico transversal, en 422 familias de la ciudad de La Paz, de los 7 Macrodistritos; Cotahuma, Max Paredes, Periférica, Centro, San Antonio, Sur y Mallasa. Se aplicó una encuesta con variables socioeconómicas (Método Graffar - Méndez Castellanos), Se registró los hábitos alimentarios (cantidad, calidad, armonía y adecuación de la dieta consumida), el acceso físico y económico a los alimentos (porcentaje de ingreso familiar destinado a la compra de los alimentos). RESULTADOS: la composición de la canasta básica de alimentos en cantidad y calidad guarda relación con factores socioeconómicos, hábitos alimentarios y el acceso físico a los alimentos. (p<0,05). Las familias compuestas por 3,5 a 4,4 miembros requieren de 2.5 a 3.5 salarios básicos, solo para cubrir el gasto en alimentación. El porcentaje de ingreso familiar destinado a la alimentación es alrededor del 40%. Las familias con menos ingresos destinan mayor porcentaje de sus ingresos a la alimentación y las familias con más ingresos destinan un menor porcentaje de sus ingresos en alimentación. CONCLUSIONES: la capacidad de compra de las familias es limitada para alcanzar una adecuada canasta alimentaria básica y está relacionado principalmente con el nivel socioeconómico, el acceso físico y económico de los alimentos y los hábitos alimentarios. Si bien el salario básico en los últimos años se incrementó, priman otros factores que determinan la composición de una Canasta Básica Alimentaria.

OBJECTIVE: to determine factors related to the composition of the nutritious food basket of families living in the city of La Paz. MATERIAL AND METHOD: this is a transversal analytical study of 422 families in the city of La Paz, of the 7 Macrodistricts: Cotahuma, Max Paredes, Periférica, Centro, San Antonio, Sur and Mallasa. A survey with socioeconomic variables (Graffar-Mendez Castellanos Method) was applied. Food habits and consumption were registered (in order to determine the quantity, quality, harmony and adaptation of the consumed diet), the physical and economic access to food (in order to determine the percent of the family's income allotted to the purchase of food). RESULTS: It can be asserted that the composition of the family's cost of the basic nutritious food basket, in quantity and quality keeps a relationship with socioeconomic factors, food habits and physical access to food with less than 5 percent significance. (p<0,05). Urban families of La Paz made up of 3,5 to 4,4 members require at least 2.5 to 3.5 minimum wages only in order to cover food expenditures. The family income percent allotted to food is around 40%. Families with lesser incomes allot a higher income percent to food and families with higher incomes allot a lesser income percent to food. CONCLUSIONS: purchase capacity of families in order to reach an adequate basic nutritious food basket is limited and it is mainly related to the socioeconomic level, the family's physical and economic access. Although minimum wages have been increased over the pastyears, there are various already mentioned factors determining the composition of a family's basic nutritious food basket.

Contribuição de cesta básica na segurança alimentar de idosos diabéticos de programa assistencial em uma cidade do sul do Brasil / Contribution of the basic food basket to the nutritional state of diabetic elderly in an assistance program in a southern Brazilian city

A garantia de acesso em quantidade, qualidade e regularidade aos alimentos é direito constitucional e humano. Em função disso, os programas públicos de segurança alimentar procuram focar suas ações nas populações de maior vulnerabilidade social. Este trabalho teve como objetivo investigar a contribuição energética e de macronutrientes da composição da cesta básica diet, oferecida pelo Programa Cidadania Alimentar (PCA) da cidade de Canoas-RS, ao estado nutricional dos idosos diabéticos. Para tanto, foi realizado estudo descritivo incluindo os 163 idosos diabéticos, de ambos os sexos, cadastrados no PCA que receberam o benefício da cesta básica diet. Constatou-se que 76,1% dos inscritos são do sexo feminino e 68,1% apresentaram classificação do índice de massa corporal (IMC) >27kg/m², indicando excesso de peso. A composição da cesta básica diet fornecida pelo PCA contemplou a média de 924,4 kcal/dia, distribuída em 54,2% de carboidratos, 13,4% de proteínas e 32,5% de gorduras. Os resultados mostraram boa adequação energética da cesta básica diet quando considerada a necessidade energética estimada (NEE) recomendada para os idosos. No entanto, sugere-se uma reavaliação do programa para que ele possa atuar em ações promotoras de saúde frente aos resultados do IMC encontrados nessa população.

Ensuring access in quantity, quality and regularity to foods is a constitutional and human right.
