Were policies in Brazil effective to reducing trans fat from industrial origin in foods?

OBJECTIVE: To determine the trans fatty acids content of processed foods frequently consumed by adults living in a Rio de Janeiro, Brazil, after the enactment of a mandatory trans fatty acids labelling policy. METHODS: Between February 2014 and January 2015, a specifically dietary questionnaire was completed by 107 adults to assess the frequency of processed foods consumption. The most commonly consumed products from the survey, including vegetable oils, margarine, biscuits, snacks, cheese bread (pão de queijo), french fries, cheeseburger and ice cream, were then analyzed for their trans fatty acids content using gas chromatography with a flame ionization detector. RESULTS: Differences in the levels of trans fatty acids were observed among 22 products analyzed, considering that trans fatty acids content ranged between 0.0 g/100 g in samples of cream cracker biscuit 1 and olive oil to 0.83 g/100 g in samples of cheeseburger ( fast food), 0.51 g/100 g in samples of frozen pão de queijo and 12.92 g/100 g in samples of chocolate sandwich cookies with cream filling 2. The overall trans fatty acids content of the different samples of margarine brands was 0.20 g/100 g for brand 1 and 0.0 g/100 g for brand 2. These data are significantly lower than those observed in a survey conducted in 2003, when the regulation had been enacted. CONCLUSIONS: Our data indicate that Brazilian regulation is very likely implicated in the observed drop in trans fatty acids of the most processed foods but has yet to eliminate them, which reinforces the urgent need to revise the legislation, since a minimum amount of trans fat does not mean that the food product does not contain this type of fat

Inadequate nutrient intake in Brazilian adolescents

OBJETIVO: Estimar o consumo de energia e nutrientes e a prevalência de inadequação da ingestão de micronutrientes entre adolescentes brasileiros. MÉTODOS: Amostra probabilística composta por 6.797 adolescentes (49,7% do sexo feminino) entre dez e 18 anos de idade foi avaliada no Inquérito Nacional de Alimentação, 2008-2009. Os fatores de expansão, a complexidade do desenho da amostra e a correção da variabilidade intrapessoal do consumo foram considerados. A prevalência de inadequação de consumo de micronutrientes foi estimada pela proporção de adolescentes com ingestão abaixo da necessidade média estimada. Para o sódio, estimou-se a prevalência de consumo acima do valor de ingestão máxima tolerável. RESULTADOS: A média de consumo de energia variou de 1.869 kcal, observada nas adolescentes de 10 a 13 anos, a 2.198 kcal, estimada para os adolescentes de 14 a 18 anos. Os carboidratos forneceram 57% da energia total, os lipídios, 27% e as proteínas, 16%. As maiores prevalências de inadequação foram observadas para cálcio (>; 95%), fósforo (entre 54% e 69%) e vitaminas A (entre 66% e 85%), E (100%) e C (entre 27% e 49%). Mais de 70% dos adolescentes apresentaram consumo de sódio superior à ingestão máxima tolerável. CONCLUSÕES: As médias de consumo energético e a distribuição de macronutrientes eram adequadas, mas foram observadas elevadas prevalências de inadequação no consumo de vitaminas e minerais, destacando-se consumo de sódio muito acima do recomendado, consumo de cálcio reduzido e nas adolescentes de 14 a 18 anos foi observada importante inadequação na ingestão de ferro.OBJETIVO: Estimar el consumo de energía y nutrientes y la prevalencia de ingestión inadecuada de micronutrientes entre adolescentes brasileños. MÉTODOS: La muestra probabilística compuesta por 6.797 adolescentes (49,7% del sexo femenino) entre diez y 18 años de edad fue evaluada en la Pesquisa Nacional de Alimentación, 2008-2009. Se consideraron los factores de expansión, la complejidad de diseño de la muestra y la corrección de la variabilidad intra-personal de consumo. La prevalencia de consumo inadecuado de micronutrientes fue estimada por la proporción de adolescentes con ingestión por debajo de la necesidad promedio estimada. Para el sodio, se estimó la prevalencia de consumo por encima del valor de ingestión máxima tolerable. CONCLUSIÓN: Los promedios de consumo energético y la distribución de macronutrientes eran adecuados, sin embargo, se observaron elevadas prevalencias de consumo inadecuado de vitaminas y minerales, destacándose el consumo de sodio muy por encima de lo recomendado, consumo de calcio reducido y en las adolescentes de 14 a 18 años fue observada importante ingestión inadecuada de hierro.OBJECTIVE: To assess energy and nutrient consumption and the prevalence of inadequate micronutrient intake among Brazilian adolescents. METHODS: A random sample composed of 6,797 adolescents (49.7% girls), between 10 and 18 years old, was evaluated in the first National Dietary Survey, part of the Household Budget Survey carried out in 2008-2009. Expansion factors, sample complexity design and correction of intraindividual variability were considered. The prevalence of inadequate micronutrient intake was based on the proportion of adolescents with intake below the Estimated Average Requirement (EAR). The prevalence of intake above the Tolerable Upper Intake Level (UL) was estimated for sodium. RESULTS: The mean energy intake ranged between 1,869 kcal (10 to 13 year old females) and 2,198 kcal (14 to 18 year old males). Of the total energy intake, 57% came from carbohydrates, 27% from lipids and about 16% from proteins. Inadequacies were higher for calcium (>; 95%), phosphorous (54% to 69%) and vitamins A (66% to 85%), E (100%) and C (27% to 49%). More than 70% of adolescents reported sodium intake above the UL. CONCLUSIONS: Mean energy consumption and distribution of macro-nutrients were adequate, but prevalence of inadequate vitamin and mineral intake were high and notable consumption of sodium above the recommended levels, low levels of calcium consumption and, in 14 to 18 year old females, important inadequacies in iron intake were found

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

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

Brazilian guidelines for the management of candidiasis - a joint meeting report of three medical societies: Sociedade Brasileira de Infectologia, Sociedade Paulista de Infectologia and Sociedade Brasileira de Medicina Tropical

Candida infections account for 80% of all fungal infections in the hospital environment, including bloodstream, urinary tract and surgical site infections. Bloodstream infections are now a major challenge for tertiary hospitals worldwide due to their high prevalence and mortality rates. The incidence of candidemia in tertiary public hospitals in Brazil is approximately 2.5 cases per 1000 hospital admissions. Due to the importance of this infection, the authors provide a review of the diversity of the genus Candida and its clinical relevance, the therapeutic options and discuss the treatment of major infections caused by Candida. Each topography is discussed with regard to epidemiological, clinical and laboratory diagnostic and therapeutic recommendations based on levels of evidence.28331
