ABSTRACT 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. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Esse estudo teve como objetivo investigar a efetividade da suplementação semanal de ferro na concentração de hemoglobina, no estado nutricional e no desenvolvimento mental e motor de lactentes em quatro creches municipais do Recife, Pernambuco, Brasil. O estudo consistiu de uma intervenção do tipo antes-depois realizada com suplementação semanal com ferro por seis meses, em uma amostra de 76 crianças com idade entre 4 e 24 meses, no período de fevereiro a dezembro de 2005. Os desenvolvimentos mental e motor foram avaliados pela Escala de Desenvolvimento Infantil de Bayley II. Após a suplementação observou-se um aumento significante na concentração de hemoglobina, apenas no grupo de lactentes com hemoglobina inicial < 9,5g/dL (p = 0,001). Para o índice peso/comprimento também se verificou um incremento significante da média de escore z, no entanto, ocorreu o oposto para o índice comprimento/idade. Não se observou diferença nos índices de desenvolvimento. Conclui-se que a suplementação semanal de ferro foi efetiva elevando a hemoglobina nos lactentes com níveis iniciais mais baixos, não se observando impacto no desenvolvimento infantil.

This study analyzed the effectiveness of weekly iron supplementation on hemoglobin concentration, nutritional status, and mental and motor development of infants at four public daycare centers in Recife, Pernambuco State, Brazil. This was a before-after intervention study conducted with weekly iron supplementation for six months in a sample of 76 infants in the 4 to 24 month age group, from February to December 2005. Mental and motor development was assessed through the Bayley Scale of Infant Development II. After supplementation, a significant increase was observed in hemoglobin concentration in the group of infants with initial hemoglobin level < 9.5g/dL (p = 0.001). There was also a significant increase in the mean weight-for-length z-score, but the opposite was found for length-for-age. No difference was observed in the developmental indices. We conclude that weekly iron supplementation was effective for increasing hemoglobin concentration in infants with lower initial levels, but no impact on infant development was observed.
