Relationship between the rs333 Polymorphism in the CC Chemokine Receptor Type Five (CCR5) Gene and Immunological Disorders: Data from a Meta-Analysis

Introduction: Inflammatory Bowel Disease (IBD), periodontitis and Systemic Lupus Erythematous (SLE) are multifactorial diseases, one of the factors in the course of these diseases is the rs333 polymorphism in the CC chemokine receptor type five (CCR5) gene. However, the results remain contradictory. Therefore, we aimed to perform a meta-analysis evaluating the relation between this polymorphism and the aforementioned conditions. Material and Methods: A search in the literature was performed in diverse scientific and medical databases for studies published before June 22, 2020. The data were extracted from the studies and the statistical evaluation was performed by the calculations of statistical heterogeneity (I²), Odds Ratio (OR) with 95% of Confidence Intervals (CI) and publication bias. The values of P<0.05 were considered as significant for all calculations. Results: 19 articles with 21 case/control studies in 4,304 case patients and 3,492 controls were included. The meta-analysis showed a non-significant association among the rs333 polymorphism and IBD (OR = 1.05, 95% CI: 0.91-1.20, P = 0.51), periodontitis (OR = 0.86, 95% CI: 0.64-1.17, P = 0.34) or SLE (OR = 1.00, 95% CI: 0.56-1.80, P = 1.00) under the allelic model or for any other performed calculation. There were no obvious publication bias in the analyses. Conclusion: In conclusion, this current meta-analysis evidenced the non-significant relation among the rs333 polymorphism and the risk of IBD, periodontitis or SLE. Further studies are required to validate our data

O clickbait no ciberjornalismo português e brasileiro: o caso brasileiro

O trabalho tem como proposta analisar a incidência de "clickbait" no jornalismo online português e brasileiro. Faz parte de uma atividade realizada em conjunto por pesquisadores brasileiros e portugueses, em que cada grupo efetuou a verificação em 18 veículos de informação geral do seu país com abrangência nacional, com produção própria e atualizada frequentemente, tanto nas páginas Web, assim como no Facebook. Este artigo traz os resultados encontrados na amostra brasileira que apontam um alto índice de "clickbait" ao se verificar os dados gerais, com 54,4% da amostra com ocorrência desta prática. Ao mesmo tempo, os valores se reduzem ao olharmos os 32 indicadores individualmente, em que apenas três tiveram índices superiores a 10%.The paper aims to analyze the incidence of clickbait in Portuguese and Brazilian online journalism.

This article presents the results found in the Brazilian sample that shows a high clickbait index, of 54.4%, when crosschecking the general data. On the other hand, the values are reduced when we look at the 32 indicators individually, in which only three had rates above 10%

O clickbait no ciberjornalismo português e brasileiro: o caso português

A investigação que aqui se apresenta partiu da proposta de analisar a incidência de clickbait no ciberjornalismo português e brasileiro. Faz parte de um projeto desenvolvido em conjunto por investigadores brasileiros e portugueses, em que cada grupo efetuou a verificação em 18 cibermeios de informação geral do seu país com abrangência nacional e com produção própria e atualizada frequentemente, tanto nas páginas Web como no Facebook. Neste artigo apresentamos os resultados encontrados nos 270 títulos/conteúdos que constituíram a amostra portuguesa, que apontam para um índice de clickbait de 39,6%. Analisando individualmente os 32 indicadores, verificamos que nenhum chega aos 10%, destacando-se como valor mais alto a "Informação empolada", presente em 8,5% da amostra.The paper aims to analyze the incidence of clickbait in Portuguese and Brazilian online journalism.

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

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning
