Desempenho anaeróbico lático e aeróbico de mulheres com ciclo menstruai ovulatório

Este trabalho analisou o comportamento das potências anaeróbica lática e aeróbica durante as fases folicular e lútea do ciclo menstruai. O exercício físico induz respostas semelhantes entre os sexos. Entretanto, a mulher sofre flutuações significativas nos caminhos fisiológicos, uma vez que seus hormônios não são secretados continua­mente durante o mês. Esse padrão rítmico é conhecido por ciclo feminino ou menstruai: este apresenta duas fases - folicular e lútea. Alguns autores afirmam que durante a fase lútea o desempenho declina, enquanto outros não encontraram diferenças. A presente amostra foi formada por 5 mulheres, com ciclo ovulatório, idade entre 20 e 40 anos, moderadamente ativas. Para verificar a potência anaeróbica lática, utilizou-se o teste em pista de atletismo de 40 segundos e para verificar a potência aeróbica, foi aplicado um teste progressivo máximo com análise direta do V02 em ciclo ergômetro. Utilizou-se a estatística descritiva, o teste t e a correlação de Pearson com um nível de significância de p<0,05. Não houve diferenças significativas nas potências anaeróbica lática e aeróbica. As variáveis fisiológicas, volume ventilatório e temperatura corporal, apresentaram respostas significativamente di­ferentes. Constatou-se ainda, casos que apresentaram queda significativa no V02 máximo

Vo2 máximo obtido com e sem teste ergométrico

Objetivo: verificar a concordância e a correlação entre duas metodologias distintas, utilizadas na obtenção do VO2  máx, as propostas por Foster et al. (T1) e Jackson et al., modelo 2, (T2). Metodologia: Os dados para análise, pertencentes a uma clínica privada em nosso município, foram obtidos mediante a assinatura dos Termos de Confidencialidade e Autorização Institucional. De acordo com os critérios de inclusão, 106 sujeitos (29 homens; 77 mulheres) formaram a amostra. O teste de Shapiro-Wilk, a análise descritiva, a análise de Bland e Altman e o coeficiente de correlação de Pearson, compuseram a análise estatística (nível de significância de 5%). Resultados: apesar das semelhanças, entre as médias obtidas, as metodologias demonstraram concordância somente no grupo masculino. Conclusão: em função dos resultados obtidos, e da enorme praticidade, sugere-se o método T2 para fins de prescrição do exercício, mas, o método T1 torna-se indispensável para avaliar a integridade do sistema cardiorrespiratório

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Choosing wisely for thyroid conditions : recommendations of the thyroid department of the Brazilian Society of Endocrinology and Metabolism

Objective: Choosing Wisely (CW) is an initiative that aims to advance the dialogue between physicians and patients about low-value health interventions. Given that thyroid conditions are frequent in clinical practice, we aimed to develop an evidence-based list of thyroid CW recommendations. Materials and methods: The Thyroid Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) named a Task Force to conduct the initiative. The Task Force work was based on an electronic Delphi approach. The 10 recommendations that received the highest scores by the Task Force were submitted for voting by all SBEM associates. The 5 recommendations that received the highest scores by SBEM associates are presented herein. Results: The Task Force was composed of 14 thyroidologists from 10 tertiary-care, teaching-based Brazilian institutions. The brainstorming/ideation phase resulted in 69 recommendations. After the removal of duplicates and recommendations that did not adhere to the initiative's scope, 35 remained. Then the Task Force voted to attribute a grade (0 [lowest agreement] to 10 [highest agreement]) for each recommendation. The 10 recommendations that received the highest scores by the Task Force were submitted to all SBEM associates. A total of 683 associates voted electronically, attributing a grade (0 to 10) for each recommendation. The 5 recommendations that received the highest scores by the SBEM associates compose our final list. Conclusion: A set of recommendations to avoid unnecessary medical tests, treatments, or procedures for thyroid conditions are offered with a transparent methodology. This initiative aims to foster productive interactions between physicians and patients, stimulating shared decision-making
