    OBJETIVO: Identificar e quantificar a influĂȘncia dos fatores socioeconĂŽmicos sobre os padrĂ”es alimentares. \ud MÉTODOS: Estudo transversal de base populacional com amostra de 1.136 crianças e adolescentes de 7 a 14 anos de idade, de ambos os sexos, matriculados na rede pĂșblica de Salvador (BA), Brasil. O consumo alimentar foi medido por meio do questionĂĄrio qualitativo de frequĂȘncia alimentar. Os padrĂ”es de consumo foram identificados por meio de anĂĄlise de componentes principais. Para o estudo da influĂȘncia dos indicadores socioeconĂŽmicos na conformação dos padrĂ”es alimentares, foram utilizados modelos de regressĂŁo quantĂ­lica. \ud RESULTADOS: Os padrĂ”es alimentares extraĂ­dos foram classificados em padrĂŁo obesogĂȘnico e padrĂŁo tradicional. Nos modelos de regressĂŁo quantĂ­lica, ajustados por faixa etĂĄria e por sexo, o menor grau de instrução materna esteve associado negativamente, em nĂ­veis significantes, na maioria dos percentis, ao consumo de alimentos que integram o padrĂŁo obesogĂȘnico. A baixa renda associou-se negativamente aos maiores percentis (p>95). Os dados indicam nĂŁo haver influĂȘncia dos indicadores socioeconĂŽmicos sobre o consumo de alimentos que integram o padrĂŁo tradicional. \ud CONCLUSÃO: Conclui-se que hĂĄ influĂȘncia dos fatores socioeconĂŽmicos na adesĂŁo ao padrĂŁo obesogĂȘnico de consumo. Esse conjunto de resultados requer a atenção dos gestores pĂșblicos para a identificação de um padrĂŁo de consumo ocidental, visualizado amplamente nos estudos em que se avaliam padrĂ”es de consumo adotados na atualidade pela população brasileira - sobretudo por crianças e adolescentes -, caracterizados por englobar componentes alimentares de risco para as doenças crĂŽnicas nĂŁo transmissĂ­veis.Objective The present study identified and quantified the influence of socioeconomic factors on dietary patterns. Methods This cross-sectional, population-based study investigated the food habits of 1136 children and adolescents of both genders, aged 7 to 14 years, enrolled in public schools of Salvador (BA), Brazil, using the qualitative food frequency questionnaire. Intake patterns were identified by principal component analysis. Quantile regression models were used to study the influence of socioeconomic indicators on dietary patterns. Results The sample's eating patterns were classified into obesogenic or traditional. Quantile regression models adjusted for age and gender showed that, for most percentiles, low maternal education level was significantly negatively associated with consumption of foods included in the obesogenic pattern. Low income was negatively associated with the highest percentiles (p >= 95). The data showed that socioeconomic indicators do not influence the consumption of foods included in the traditional pattern. Conclusion Socioeconomic factors promote adherence to obesogenic eating patterns. These results indicate that public authorities need to identify the Western consumption pattern, commonly observed in studies that assess the current consumption patterns of the Brazilian population, especially of children and adolescents, characterized by foods that promote non-communicable chronic diseases

This is an open access article under the CC-BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/).Introduction: Patient selection for percutaneous coronary intervention (PCI) in chronic total occlusions (CTOs) is crucial to procedural success. Our aim was to identify independent predictors of success in CTO PCI in order to create an accurate score. Methods: In a single-center observational registry of CTO PCI, demographic and clinical data and anatomical characteristics of coronary lesions were recorded. Linear and logistic regression analysis were used to identify predictors of success. A score to predict success was created and its accuracy was measured by receiver operating curve analysis. Results: A total of 377 interventions were performed (334 patients, age 68±11 years, 75% male). The success rate was 65% per patient and 60% per procedure. Predictors of success in univariate analysis were absence of active smoking (OR 2.02, 95% CI 1.243-3.29; p=0.005), presence of tapered stump (OR 5.2, 95% CI 2.7-10.2; p8 with high probability (95%). Conclusion: In our sample only anatomical characteristics were predictors of success. The creation of a score to predict success, with good accuracy, may enable selection of cases that can be treated by any operator, those in which a dedicated operator will be desirable, and those with an extremely low probability of success, which should be considered individually for conservative management, surgical revascularization or PCI by a team experienced in CTO.info:eu-repo/semantics/publishedVersio

    Rede Portuguesa de LaboratĂłrios para o DiagnĂłstico da GripeBACKGROUND: Population immune profile for influenza is highly affected by circulating influenza viruses, thus changing the risk of infection for influenza. This study aims to assess influenza immunity in the Portuguese population by age groups, during 2014 and 2015 and establish a relationship between seroprotection and circulating influenza viruses in 2014/15 and 2015/16 seasons. METHODS: Two cross-sectional studies were developed based on a convenience serum sample collected in June 2014 (n=626) and July 2015 (n=675) in hospitals from mainland and Azores and Madeira.Serums equally represent all age groups. Antibody titers were evaluated by HI assay for strains recommended for seasonal influenza vaccine northern hemisphere,2014/15 and 2015/2016. Seroprevalences were estimated for each strain by age group and the association with seasonal cumulative influenza-like illness (ILI) rates for influenza virus during both seasons was analised. RESULTS: In June 2014 the highest seroprotection was observed for influenza A(H3) (39.0%; 95% CI: 36.2-43.8%) and A(H1)pdm09 (29.7; 95% CI: 26.3-33.4%), with higher levels in children 5-14 years old. In 2014/2015 a dominant circulation of influenza B/Yamagata was observed with high incidence rates in individuals under 65 years old, the ones that had lower seroprotection. Although before the start of the season high protection for A(H3) was observed, the circulation of the new drift A(H3) strains had gained an immunological advantage,in accordance with A(H3) elevated incidence rates observed during 2014/15. In July 2015 the highest seroprotection was observed for influenza B/ Yamagata (55.1%; 95% CI: 51.4-58.9%), 2.4 times the estimated 2014.This increase was even more pronounced in younger (≀ 4 years old), 6.3 times increase in 2015.This fact is in agreement with the predominant influenza B virus detected and the high ILI incidence rate observed in children during 2014/2015 epidemic. Seroprotection levels for influenza A in July 2015 were not significantly different from 2014.During 2015/16 season, influenza A(H1N1)pdm09 was predominant, with high incidence rate in < 65 year old. Influenza B/Victoria lineage,although detected at low levels increased in frequency, in agreement with the lowest level of seroprotection detected in the general population before the start of 2015/2016 season (21.8%; 95% CI: 18.7-24.0%). CONCLUSIONS There was a correlation between virus circulation, incidence rates for each age group and the previous seroprotection for seasonal influenza viruses.Our study highlights the value of measuring the serological profile for influenza to establishe risk groups for infection for which an increase preventive measures, including vaccination, should be fostered.info:eu-repo/semantics/publishedVersio

    This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.&nbsp; Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities. &nbsp; Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.&nbsp; The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.&nbsp; The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.&nbsp; &nbsp;&nbsp; Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidĂȘncias cientĂ­ficas que as suportam, quanto ao diagnĂłstico e tratamento da CDC, com especial ĂȘnfase na base de racionalidade que a embasou. A DC no sĂ©culo XXI mantĂ©m padrĂŁo epidemiolĂłgico de endemicidade em 21 paĂ­ses da AmĂ©rica Latina. Investigadores e gestores de paĂ­ses endĂȘmicos e nĂŁo endĂȘmicos indigitam a necessidade de se adotarem polĂ­ticas abrangentes, de saĂșde pĂșblica, para controle eficaz da transmissĂŁo inter-humanos da infecção pelo T. cruzi, e obter-se nĂ­vel otimizado de atendimento aos indivĂ­duos jĂĄ infectados, com foco em oportunização diagnĂłstica e terapĂȘutica. Mecanismos patogĂȘnicos e fisiopatolĂłgicos da CDC foram revisitados apĂłs atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistĂȘncia parasitĂĄria tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distĂșrbios autonĂŽmicos e microvasculares. Alguns deles recentemente constituĂ­ram alvos potenciais de terapĂȘuticas. A histĂłria natural das fases aguda e crĂŽnica foi revista, com realce para a transmissĂŁo oral, a forma indeterminada e as sĂ­ndromes crĂŽnicas. MetanĂĄlises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade apĂłs instalação da cardiomiopatia crĂŽnica. Condutas terapĂȘuticas aplicĂĄveis aos indivĂ­duos com a FIDC foram abordadas especificamente. Todos os mĂ©todos para detectar alteraçÔes estruturais e/ou funcionais com variadas tĂ©cnicas de imageamento cardĂ­aco tambĂ©m foram revisados, com recomendaçÔes de uso nos vĂĄrios cenĂĄrios clĂ­nicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por mĂ©todos que detectam fibrose miocĂĄrdica. A metodologia atual para diagnĂłstico etiolĂłgico e as consequentes implicaçÔes do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. TambĂ©m o tratamento de pacientes em risco ou com insuficiĂȘncia cardĂ­aca, arritmias e eventos tromboembĂłlicos, baseado em recursos farmacolĂłgicos e complementares, recebeu especial atenção. CapĂ­tulos suplementares subsidiaram as condutas aplicĂĄveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grĂĄvidas, na reativação da infecção apĂłs transplante cardĂ­acos, e outros.&nbsp;&nbsp;&nbsp; Por fim, dois capĂ­tulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivĂ­duos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicaçÔes mĂ©dico-trabalhistas completaram esta diretriz.&nbsp

    The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2,MaNGA, and eBOSS. In addition, eBOSS contains two major subprograms: TDSS and SPIDERS. This paper describes the first data release from SDSS-IV, Data Release 13 (DR13), which contains new data, reanalysis of existing data sets and, like all SDSS data releases, is inclusive of previously released data. DR13 makes publicly available 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA,the first data released from this survey. It includes new observations from eBOSS, completing SEQUELS. In addition to targeting galaxies and quasars, SEQUELS also targeted variability-selected objects from TDSS and X-ray selected objects from SPIDERS. DR13 includes new reductions ofthe SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification. DR13 releases new reductions of the APOGEE-1data from SDSS-III, with abundances of elements not previously included and improved stellar parameters for dwarf stars and cooler stars. For the SDSS imaging data, DR13 provides new, more robust and precise photometric calibrations. Several value-added catalogs are being released in tandem with DR13, in particular target catalogs relevant for eBOSS, TDSS, and SPIDERS, and an updated red-clump catalog for APOGEE.This paper describes the location and format of the data now publicly available, as well as providing references to the important technical papers that describe the targeting, observing, and data reduction. The SDSS website, http://www.sdss.org, provides links to the data, tutorials and examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned ~6-year operations of SDSS-IV.PostprintPeer reviewe

    The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new near-infrared high-resolution spectrograph, and a novel optical interferometer. All of the data from SDSS-III are now made public. In particular, this paper describes Data Release 11 (DR11) including all data acquired through 2013 July, and Data Release 12 (DR12) adding data acquired through 2014 July (including all data included in previous data releases), marking the end of SDSS-III observing. Relative to our previous public release (DR10), DR12 adds one million new spectra of galaxies and quasars from the Baryon Oscillation Spectroscopic Survey (BOSS) over an additional 3000 deg2 of sky, more than triples the number of H-band spectra of stars as part of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE), and includes repeated accurate radial velocity measurements of 5500 stars from the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS). The APOGEE outputs now include the measured abundances of 15 different elements for each star. In total, SDSS-III added 5200 deg2 of ugriz imaging; 155,520 spectra of 138,099 stars as part of the Sloan Exploration of Galactic Understanding and Evolution 2 (SEGUE-2) survey; 2,497,484 BOSS spectra of 1,372,737 galaxies, 294,512 quasars, and 247,216 stars over 9376 deg2; 618,080 APOGEE spectra of 156,593 stars; and 197,040 MARVELS spectra of 5513 stars. Since its first light in 1998, SDSS has imaged over 1/3 of the Celestial sphere in five bands and obtained over five million astronomical spectra. \ua9 2015. The American Astronomical Society
