    INTRODUCTION: The consumption of ultra-processed foods (UPF) increases the risk for obesity development; however, the size and impact of this risk has not yet been quantified. OBJECTIVE: To determine the magnitude of UPF consumption in transition of nutritional status of overweight for obesity. METHODS: This observational study was conducted from the data of 15.024 adults of 18 to 59 years (Women: 56%), of the project Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL) of 2019. The nutritional status was determined through the body mass index (BMI). Values of BMI between 25 to 29.99 kg/m2 were classified as overweight (n=9618), and when ≥30kg/m2, they are obese (n=5406). The consumption of UPF was considered low (<9 units/day) or high (≥10 units/day). The risk factors: age, sex, scholarity, consumption <9 minimally processed foods (MPF), physical inactivity (≤150min/week of moderate to vigorous intensity), screen time per day, consumption of alcohol (yes/no), weekly consumption of tobacco (n° of cigarettes/week), high blood pressure (systolic >120mm/Hg and/or diastolic >80mm/Hg) and hyperglycemia (≥126mg/dL) were introduced on model of binary logistic regression for the calculus of Odds Ratio (OR) occurrence. RESULTS: The analysis showed that consumption of ≥10 UPF increases in 37% the odd of occurrence of obesity, regardless of other risk factors as: physical inactivity (OR=+26,1%), screen time (OR=+6,5%), consumption of ≥10 MPF (OR=-59%), absence of high-pressure levels (OR=-52,6%), of hyperglycemia (OR=-29,6%) and major scholarity (OR=-2,1%). CONCLUSION: The size of success in the intervention strategies for the prevention of obesity now is known. The effective intervention involves primarily factors like reduction of UPF consumption and increases of MPF consumption, with impact magnitude of 37% and 59% respectively.INTRODUCCIÓN: El consumo de alimentos ultraprocesados ​​(AUP) aumenta el riesgo de desarrollar obesidad, sin embargo, aún no se ha cuantificado el tamaño y el impacto de este riesgo. OBJETIVO: Determinar la magnitud del consumo de AUP en la transición del estado nutricional del sobrepeso a la obesidad. MÉTODOS: Este estudio observacional se realizó con datos de 15.024 adultos de 18 a 59 años (Mujeres: 56%), del proyecto Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL) de 2019.

    Introduction: Inflammatory conditions of the nose and paranasal sinuses are very prevalent in the general population, resulting in marked loss of quality of life in affected patients, as well as significant work, leisure, and social activity losses. These patients require specific and specialized treatment. A wide range of oral medications are available. Objective: The present document is aimed to clarify, for professionals treating patients with inflammatory sinonasal diseases, both specialists and general practitioners, specific oral therapies in noninfectious nasal inflammatory conditions. Methods: The methodology used to create this article included the search for the key words: oral corticosteroids, antihistamines, antileukotrienes, rhinitis, rhinosinusitis in the MEDLINE and EMBASE databases in the last 5 years. Since no relevant article was found for the text on the subject of interest in the last 5 years, the search was extended for another 5 years, and so on, according to the authors' needs. Results: Relevant literature was found regarding the use of antihistamines, antileukotrienes and oral corticosteroids in these conditions. The Brazilian Academy of Rhinology emphasizes, after extensive discussion by the collegiate, key points in the treatment with these drugs. Conclusion: There is support in the literature for the use of these drugshowever, final considerations about the role of each of them have been made.

    Standalone vertex finding in the ATLAS muon spectrometer

    Get PDF
    A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011

    Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

    Get PDF
    Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson

    Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb−1 of √s=7 TeV proton-proton collisions

    Get PDF
    Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb−1 of pp collision data at s√=7TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from ≥6 to ≥9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m 0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV

    Lidar Observations in South America. Part I - Mesosphere and Stratosphere

    Get PDF
    South America covers a large area of the globe and plays a fundamental function in its climate change, geographical features, and natural resources. However, it still is a developing area, and natural resource management and energy production are far from a sustainable framework, impacting the air quality of the area and needs much improvement in monitoring. There are significant activities regarding laser remote sensing of the atmosphere at different levels for different purposes. Among these activities, we can mention the mesospheric probing of sodium measurements and stratospheric monitoring of ozone, and the study of wind and gravity waves. Some of these activities are long-lasting and count on the support from the Latin American Lidar Network (LALINET). We intend to pinpoint the most significant scientific achievements and show the potential of carrying out remote sensing activities in the continent and show its correlations with other earth science connections and synergies. In Part I of this chapter, we will present an overview and significant results of lidar observations in the mesosphere and stratosphere. Part II will be dedicated to tropospheric observations
