A Interferência do doce de leite como pré-treino na performance dos praticantes de Crossfit

Introduction: Crossfit® is a high intensity training program, with functional movements. High intensity exercises demand an adequate energy intake, mainly of carbohydrates to promote glycemic homeostasis, providing energy for the activities that will be performed and delaying fatigue. There are several resources to promote a better performance in physical activity practitioners, one of them is the ergogenic resource, which has the function of promoting improvement in the ability to develop muscle work. Objective: To verify the influence of dulce de leche as an energy source on the performance of Crossfit® practitioners. The participants performed a Crossfit® workout, being 21-15-9 deadlifts and burpee over bar, with a time limit of five minutes. The training was done three times with an interval of at least five days from one training to the other, with the use of dulce de leche during the activities, which could be 15g and 30g of the candy, and one week in which there was no candy ingestion. It was done randomly, with no rules for the weeks. Results: There was an improvement in the participants' performance when comparing the training with the candy to the training without the candy. The results showed an increase in repetitions per minute of 9.36% when comparing 0g to 15g of dulce de leche and of 12.42% when comparing 0g to 30g of dulce de leche. Conclusion: We conclude that the dulce de leche as pre-workout can promote improvement in performance.Introdução: O Crossfit® é um treinamento de alta intensidade, com movimentos funcionais.

Diversity of group A rotavirus genes detected in the Triângulo Mineiro region, Minas Gerais, Brazil

AbstractGroup A rotaviruses are the main causative agent of infantile gastroenteritis. The segmented nature of the viral genome allows reassortment of genome segments, which can generate genetic variants. In this study, we characterized the diversity of the VP7, VP4 (VP8*), VP6, NSP4, and NSP5 genes of the rotaviruses that circulated from 2005 to 2011 in the Triângulo Mineiro (TM) region of Brazil. Samples with genotypes G2 (sublineages IVa-1 and IVa-3), G1 (sublineage I-A), G9 (lineage III), G12 (lineages II and III), G8 (lineage II), G3 (lineage III), P[4] (sublineages IVa and IVb), P[8] (sublineages P[8]-3.6, P[8]-3.3, and P[8]-3.1), I2 (lineage VII), E2 (lineages VI, XII, and X), and H2 (lineage III) were identified. The associations found in the samples were G1, G9, or G12 with P[8]-I1-E1-H1; G2 or G8 with P[4]-I2-E2-H2; G12 with I3-E3-H6; and G3 with P[4]-I2-E3-H3 (previously unreported combination). Reassortment events in G2P[4] strains and an apparent pattern of temporal segregation within the lineages were observed. Five TM samples contained genes that exhibited high nucleotide and amino acid identities with strains of animal origin. The present study includes a period of pre- and post-introduction of rotavirus vaccination in all Brazilian territories, thereby serving as a basis for monitoring changes in the genetic constitution of rotaviruses. The results also contribute to the understanding of the diversity and evolution of rotaviruses in a global context

Returns to publicly owned transport infrastructure investment. A cost function/cost share approach for Norway, 1971-1991

An issue of major concern to politicians and policy-makers around the world today is whether transport infrastructure investments, such as those in roads and airports, generate enough economic benefits to justify their very large price tag. Beginning in the mid 1970s, nearly all OECD countries experienced a sustained decline both in public investment and in private sector output. Since infrastructure comprises the vast majority of public capital in these countries, this led many economists to conclude that underinvestment in infrastructure was largely responsible for the low growth rates in output and productivity which were experienced by these countries. In our paper, we discuss the findings in the literature with respect to both econometric and modeling deficiencies. Based on these criticisms, we develop a cost function modeling approach which includes public transport infrastructure capital, perform an econometric analysis and discuss several of our estimates of infrastructure productivity effects. The paper concludes that, in nearly all production sectors (except oil/agriculture), the public transport infrastructure investments made in Norway over the last 20 years significantly reduced private production costs and altered demand for private inputs. However, we find such effects to be statistically insignificant at the aggregate level.Norges Forskningsråd (Society, Environment and Energy program (SAMMEN))publishedVersio

Nurses' involvement in the development and usability assessment of an innovative peripheral intravenous catheterisation pack: a mix-method study

Guaranteeing peripheral venous access is one of the cornerstones of modern healthcare. Recent evidence shows that the lack of adequate clinical devices can result in the provision of substandard care to patients who require peripheral intravenous catheterization (PIVC). To address this challenge, we aimed to develop a PIVC pack for adult patients and assess the usability of this new device. Methods: Following a mix-method design, the PIVC pack development and usability assessment were performed in two phases with the involvement of its potential end-users (nurses). In phase one (concept and semi-functional prototype assessment), focus group rounds were conducted, and a usability assessment questionnaire was applied at each stage. In phase two (pre-clinical usability assessment), a two-arm crossover randomised controlled trial (PIVC pack versus traditional material) was conducted with nurses in a simulated setting. Final interviews were conducted to further explore the PIVC pack applicability in a real-life clinical setting. Results: High average usability scores were identified in each study phase. During the pre-clinical usability assessment, the PIVC pack significantly reduced procedural time (Z = −2.482, p = 0.013) and avoided omissions while preparing the required material (Z = −1.977, p = 0.048). The participating nurses emphasised the pack’s potential to standardise practices among professionals, improve adherence to infection control recommendations, and enhance stock management. Conclusions: The developed pack appears to be a promising device that can assist healthcare professionals in providing efficient and safe care to patients requiring a PIVC. Future studies in real clinical settings are warranted to test its cost-effectiveness.info:eu-repo/semantics/publishedVersio

DIVERSIDADE GENÉTICA DE Psidium guineense EM DUAS LOCALIDADES NO ESPÍRITO SANTO

Resumo: Psidium guineense Swartz pertence à família Myrtaceae, oferece potencial para exploração comercial e em virtude das propriedades nutricionais e farmacêuticas desperta a atenção da indústria. Entretanto, por ser uma espécie poliplóide, estudos de diversidade genética são escassos, dado a dificuldade das análises. O objetivo deste estudo foi avaliar a diversidade genética de duas populações P. guineense em dois municípios do estado do Espírito Santo, utilizando sete marcadores microssatélites. Todos os locos analisados foram polimórficos com média de 11,14 por locus. O método UPGMA agrupou os genótipos em dois grupos principais, diferenciando as populações das duas localidades. Dois índividuos de Águia Branca alocaram-se separadamente dos demais, demonstrando divergência genética. Os marcadores SSR utilizados neste estudo demonstraram eficiência na detecção de polimorfismos moleculares, revelando que houve grande diversidade genética entre os indivíduos das duas populações amostradas, sendo importantes para o melhoramento e conservação da espécie

Implementation of clinical guidelines in Brazil : should academic detailing be used?

Objective: The Brazilian National Health System provides high cost medicines through the Specialized Component of Pharmaceutical Assistance in accordance with adherence to agreed Clinical Guidelines. However, physician compliance to these Guidelines, as well as the barriers and facilitators related to them and the influence on the subsequent quality of care provided is unknown. Consequently, the objectives of this paper are to undertake a review of international experiences and scientific publications of a strategy to disseminate and communicate guidelines to physicians through Academic Detailing. Subsequently use the findings to develop and conduct a pilot Academic Detailing Program in Brazil targeting specialists who prescribe medicines for patients with Alzheimer’s disease, which are part of the Specialized Component of Pharmaceutical Assistance. Methods: Review international experiences and scientific publications relating to academic detailing based on a thorough review of available literature including publications known to the co-authors. Develop and monitor physician acceptance of academic detailing for patients with Alzheimer’s Disease and the impact on future prescribing. Key findings: Based on the lessons learnt from the international experience and review, coupled with the initial experiences in Brazil, we conclude that conducting academic detailing to enhance the implementation and dissemination of clinical protocols and therapeutic guidelines in Brazil is worthwhile. We will be closely monitoring the outcome of the pilot academic detailing programme as a basis for developing future programmes to further improve the quality of prescribing in Brazil. Conclusion: Findings from the experiences are encouraging. This will be further explored to provide a basis for this approach in the future
