    Aim:The purpose of this studywas to assess whether individuals with active caries lesions treated with professional topical application of fluoride at high concentrations show a lower incidence of caries than individuals who have not received professional treatment with fluoridated products. Literature review:Randomized clinical trials in which patients were followed up for at least 6 months were included. Studieswere identified with MEDLINE, Embase, LILACS, SCOPUS, and Cochrane Database of Systematic Reviews. Pairs of reviewers independently conducted study selection, data extraction, and risk-of-bias assessments. Eight trials, which included 5018 children and adolescents, were eligible. Results were evaluated by calculating the preventive fraction to standardize the outcomes.Results:Fluoride varnish yielded a better preventive fraction (90.18% to 14.6%) in both primary and permanent dentitions in comparison with methods using gel (22.3% to 6%) and foam (24%) after a mean follow-up period of 20.6 months. Regardless of the product used, increased frequency of application yielded greater benefit. Discussion:Theseresults do not agree with previous findings that, in 8 weeks periods, did not observe an additional effect of the professional use of fluorides over the control treatments(biofilm control). The presentreview indicatesthe need for long-term monitoring of the effect of treatment, whereby the effects of high fluoride concentrations may appear. Conclusion:Professional fluoride treatment proved to be effective in preventing new long-term injuries in both primary and permanent dentition, irrespective of the vehicle used (varnish, gel, or foam). (PROSPERO Register number CRD42021210740).Objetivo: Avaliar se indivíduos com lesões ativas de cárie tratadas com aplicação tópica profissional de fluoretos em altas concentrações apresentam menor incidência de cárie do que indivíduos que não receberam este tratamento. Revisão da literatura: Ensaios clínicos randomizados, com acompanhamento de pelo menos 6 meses foram incluídos. Os estudos foram identificados nas bases de dados MEDLINE, Embase, LILACS, SCOPUS e Cochrane Database of Systematic Reviews. Pares de revisores conduziram de forma independente a seleção de estudos, extração de dados e avaliações de risco de viés. Oito estudos, que incluíram 5.018 crianças e adolescentes, foram elegíveis. Os resultados foram avaliados por meio do cálculo da fração preventiva. Resultados:O verniz fluoretado apresentou melhor fração preventiva (90,18% a 14,6%), tanto na dentição decídua quanto na permanente, em comparação com os métodos com gel (22,3% a 6%) e espuma (24%) após um período médio de seguimento de 20,6 meses. Independentemente do produto utilizado, o aumento da frequência de aplicação apresentou maior benefício. Discussão:Estes resultados diferem de achados anteriores em que, em períodos de 8 semanas, não houve efeito adicional do uso profissional de fluoretos em relação ao tratamento controle. A presente revisão indicou a necessidade de monitoramento a longo prazo do efeito do tratamento, quando os efeitos do fluoreto de alta concentração podem aparecer. Conclusão: O tratamento profissional com flúor mostrou-se eficaz na prevenção de novas lesões a longo prazo, tanto na dentição decídua quanto na permanente, independente do veículo utilizado (verniz, gel ou espuma).

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Alcohol use and burden for 195 countries and territories, 1990-2016 : a systematic analysis for the Global Burden of Disease Study 2016

    Background Alcohol use is a leading risk factor for death and disability, but its overall association with health remains complex given the possible protective effects of moderate alcohol consumption on some conditions. With our comprehensive approach to health accounting within the Global Burden of Diseases, Injuries, and Risk Factors Study 2016, we generated improved estimates of alcohol use and alcohol-attributable deaths and disability-adjusted life-years (DALYs) for 195 locations from 1990 to 2016, for both sexes and for 5-year age groups between the ages of 15 years and 95 years and older. Methods Using 694 data sources of individual and population-level alcohol consumption, along with 592 prospective and retrospective studies on the risk of alcohol use, we produced estimates of the prevalence of current drinking, abstention, the distribution of alcohol consumption among current drinkers in standard drinks daily (defined as 10 g of pure ethyl alcohol), and alcohol-attributable deaths and DALYs. We made several methodological improvements compared with previous estimates: first, we adjusted alcohol sales estimates to take into account tourist and unrecorded consumption; second, we did a new meta-analysis of relative risks for 23 health outcomes associated with alcohol use; and third, we developed a new method to quantify the level of alcohol consumption that minimises the overall risk to individual health. Findings Globally, alcohol use was the seventh leading risk factor for both deaths and DALYs in 2016, accounting for 2.2% (95% uncertainty interval [UI] 1.5-3.0) of age-standardised female deaths and 6.8% (5.8-8.0) of age-standardised male deaths. Among the population aged 15-49 years, alcohol use was the leading risk factor globally in 2016, with 3.8% (95% UI 3.2-4-3) of female deaths and 12.2% (10.8-13-6) of male deaths attributable to alcohol use. For the population aged 15-49 years, female attributable DALYs were 2.3% (95% UI 2.0-2.6) and male attributable DALYs were 8.9% (7.8-9.9). The three leading causes of attributable deaths in this age group were tuberculosis (1.4% [95% UI 1. 0-1. 7] of total deaths), road injuries (1.2% [0.7-1.9]), and self-harm (1.1% [0.6-1.5]). For populations aged 50 years and older, cancers accounted for a large proportion of total alcohol-attributable deaths in 2016, constituting 27.1% (95% UI 21.2-33.3) of total alcohol-attributable female deaths and 18.9% (15.3-22.6) of male deaths. The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0.0-0.8) standard drinks per week. Interpretation Alcohol use is a leading risk factor for global disease burden and causes substantial health loss. We found that the risk of all-cause mortality, and of cancers specifically, rises with increasing levels of consumption, and the level of consumption that minimises health loss is zero. These results suggest that alcohol control policies might need to be revised worldwide, refocusing on efforts to lower overall population-level consumption.Peer reviewe

    Genetic Drivers of Heterogeneity in Type 2 Diabetes Pathophysiology

    Get PDF
    Type 2 diabetes (T2D) is a heterogeneous disease that develops through diverse pathophysiological processes1,2 and molecular mechanisms that are often specific to cell type3,4. Here, to characterize the genetic contribution to these processes across ancestry groups, we aggregate genome-wide association study data from 2,535,601 individuals (39.7% not of European ancestry), including 428,452 cases of T2D. We identify 1,289 independent association signals at genome-wide significance (P \u3c 5 × 10-8) that map to 611 loci, of which 145 loci are, to our knowledge, previously unreported. We define eight non-overlapping clusters of T2D signals that are characterized by distinct profiles of cardiometabolic trait associations. These clusters are differentially enriched for cell-type-specific regions of open chromatin, including pancreatic islets, adipocytes, endothelial cells and enteroendocrine cells. We build cluster-specific partitioned polygenic scores5 in a further 279,552 individuals of diverse ancestry, including 30,288 cases of T2D, and test their association with T2D-related vascular outcomes. Cluster-specific partitioned polygenic scores are associated with coronary artery disease, peripheral artery disease and end-stage diabetic nephropathy across ancestry groups, highlighting the importance of obesity-related processes in the development of vascular outcomes. Our findings show the value of integrating multi-ancestry genome-wide association study data with single-cell epigenomics to disentangle the aetiological heterogeneity that drives the development and progression of T2D. This might offer a route to optimize global access to genetically informed diabetes care
