An overview of how the curricula taken by future chemistry teachers in southeastern Brazil's public universities approach environmental issues

This work analysed the contents of 701 disciplines from 22 chemistry courses that prepare chemistry teachers in 16 public Universities in Southeastern Brazil. Only a small number (23) of disciplines showed an explicit relationship between human activities and the environment. A total of 11 theoretical and 193 experimental disciplines explored to some extent scientific and technological aspects related to the environment, but did not include their relationship with society. As the experimental disciplines supposedly include some kind of waste treatment, this may explain why secondary school chemistry teachers work mainly on recycling programs and waste issues at their schools. The aim of this work is to provide information on which to base a much needed discussion about how to better prepare our chemistry teachers to act as Environmental Educators at school, as the Brazilian Education Legislation requires

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

Ocorrência de Ansiedade e Depressão em Pacientes com Síndrome do Intestino Irritável: Revisão Sistemática com Meta-análise / Occurrence of Anxiety and Depression in Patients with Irritable Bowel Syndrome: Systematic Review with Meta-analysis

Objetivo – correlacionar a Síndrome do Intestino Irritável (SII) com as desordens neurológicas de ansiedade e depressão. Métodos – Foram incluídos estudos do tipo caso-controle em humanos publicados no período de 1999 a 2021. Os dados coletados foram: local onde o estudo foi realizado, autor, ano de publicação, número total de casos e controles, número de indivíduos com SII e número de indivíduos com ansiedade e depressão. Resultados – Para a meta-análise foram selecionados 10 estudos, incluindo um total de 25.466 pacientes assim distribuídos: 5.747 pacientes com a SII, como grupo caso, e 19.719 pacientes como grupo controle. Sendo que dos pacientes com SII, 1.005 (17,49%) desenvolveram ansiedade e depressão enquanto no grupo controle foram 886 pacientes (4,49%), os sexos e idades foram similares em ambos os grupos. Conclusão – Os indivíduos com Síndrome do Intestino Irritável possem maiores chances de desenvolver ansiedade e depressão do que os indivíduos sem Síndrome do Intestino Irritável ou saudáveis
