This article describes the adaptation of the adult Portuguese version of the General Nutrition Knowledge Questionnaire (GNKQ) for adolescents, and its validation. Respondents were 1,315 adolescents, who completed the questionnaire in two phases. A subsample of 73 adolescents was used to measure test-retest reliability. Concurrent validity was tested using a sample of 32 dietetic students. The adapted version showed high internal consistency (Cronbach's alpha = 0.92), test-retest reliability (R = 0.71) and concurrent validity (U = 22766.0; p < .01). Adolescents' nutrition knowledge can now be assessed with a valid and reliable instrument. Future validation works of this or others questionnaires for children and elderly are warranted.

This study investigates the effect of olive leaf tea (OLT) on postprandial glycemia in healthy volunteers when ingested with a high-carbohydrate meal, compared with a placebo tea (CON). Healthy adults participated in a double-blind, randomized, placebo-controlled, and cross-over design trial receiving a high-rich carbohydrate meal with either 250 mL of OLT or CON at two different times after a washout period. The sequence order was randomized at a ratio of 1:1. Capillary blood glucose was measured in a 2 h period after ingestion. Eighteen participants were initially randomized. Of these, thirteen completed the trial and were analyzed. The consumption of OLT resulted in a delay in peak time (48.5 ± 4.2 min vs. 35.7 ± 4.0 min, p = 0.03) and a significant increase in glucose area under the curve compared to placebo (14,502.7 ± 640.8 vs. 13,633.3 ± 869.4 mg/dL·min, p = 0.03). Results are depicted as mean ± SEM. The OLT and CON palatability were generally well accepted. No adverse effects were reported. OLT did not ameliorate a glycemic curve induced by carbohydrate-rich meal ingestion, suggesting that at least when ingested acutely in a single meal, OLT does not have antihyperglycemic effects. Future studies should account for chronic consumption providing a better understanding of glycemic regulation over time.

Objective: The objective of this study is to analyze hackathon contributions as an instrument for innovation in collaborative networks. Methodology: A bibliometry was performed in the Scopus and Web of Science bases through the Bibliometrix packages and the R Studio software. Publications analysis techniques were used describing the year and the group of origin (by Bradford Law), authorship analysis by the authors' relevance and their productivity (by Lotka Law), scientific contributions by country and collaboration between countries, Quotations of document with the cloud of word, as well as a thematic description of the hackathons universe. Results: An exponential increase in scientific hackathon publications from 2019 has been verified. Hackathon studies address and connect the theme mainly with innovation, collaboration, open data, education and covid-19. The increase of hackathon studies occurred during the pandemic period. Limitations: The study was delimited in two databases (Scopus and Web of Science), and in the English language. The expansion to other bases and languages ​​can produce different results from the above, and represents a limitation of this study. Originality: The analyzes performed in this study made it possible to structuring the scientific literature on hackathon.

O tema deste artigo é o comparar através do cluster (Aglomeração) das principais atividades empresariais de comércio e de serviço relacionadas a Micro, Pequenas e Médias Empresas (MPMEs) no bairro do Rio Vermelho e adjacências (Salvador -Bahia), que sobreviveram antes da pandemia (ano de 2020) e após pandemia (ano de 2023) a partir do CVO denominado Modelo do Estágios de Desenvolvimento. Toda a análise foi feita a partir de Um Estudo de Cao com o uso da metodologia da Inteligência Competitiva (IC). A partir da seguinte pergunta: Qual a porcentagem de Micro, Pequenas e Médias Empresas (MPMEs) no bairro do Rio Vermelho e adjacências (Salvador-Bahia) conseguiram sobreviver no ano de 2023 (Período pós pandemia)? O objetivo geral é quantificar as Micro, Pequenas e Médias Empresas no bairro do Rio Vermelho e adjacências (Salvador -Bahia) que permaneceram no 2023. Tem-se como resultado que 63,62% das empresas continuaram no mercado; 17,22 % morreram e 19,16% são novos empreendimentos.

Childhood obesity is according to the World Health Organization one of the most concerning problems today. Educating children to a healthier lifestyle is a difficult task due to the lack of interest or concern that they demonstrate. The interest that children have in technology and the time they spent online in games or simply surfing the web may be seen as an opportunity to instill knowledge about healthy eating and healthy lifestyle. There are already several online health counseling websites but it seems to exist a lack of such platforms directly towards to children. Afina-te website is an online platform that aims to monitor and educate children to a healthier lifestyle through the exposition of information, interactive applications and educational games. It is also capable of provide feedback about what users eat and the exercise they practice. This paper describes the development and resulting health counseling website.
