Incidence of binge drinking in a cohort of university students of the south-east region of brazil, 2010-2011.

Objectives: The aim of the present study was to evaluate the prevalence and incidence of binge and at-risk alcohol consumption among new-entrant students in a public university in the South-East Region of Brazil. Methods: Longitudinal study undertaken with a random sample of undergraduates (N=1,168) in the first semesters of 2010 (n=256) and 2011 (n=183). In order to evaluate drinking patterns, participants were classified as abstainers, light, moderate, binge or heavy binge drinkers. The Alcohol Use Disorders Identification Test (AUDIT) questionnaire score was used to define the risk categories for consumption: low risk, risk, harmful use and probable dependence. Statistical analysis was undertaken using Stata software, version 11.0. Results: Amongst the 256 students evaluated, 51.6% were women and 64.5% were aged ?19 years. The prevalence of consumption of alcoholic beverages was 75.8%. The average age of onset of alcohol consumption was 15.7?1.9 years. The incidence of binge + heavy drinkers was 2.6/100 persons per year, with vulnerability shown in individuals of male sex and of age 19 years or more. The incidence of risk level drinkers was 2.0/100 persons per year and greater for individuals of male sex and younger than 19 years. Conclusion: The students of this institution are at high risk for problems associated with alcohol use

Diagnosis : a future field of medical activity.

O sequenciamento de ?ltima gera??o (NGS) ? um tipo de tecnologia de sequenciamento de DNA que usa o sequenciamento paralelo de m?ltiplos fragmentos pequenos de DNA. Essa tecnologia permitiu um aumento dram?tico na velocidade (e uma diminui??o no custo) na qual o genoma de um indiv?duo pode ser sequenciado. O sequenciamento de Sanger ? usado para confirmar a presen?a de muta??es espec?ficas identificadas pela NGS em situa??es cl?nicas, devido ? maior precis?o dos m?todos tradicionais de sequenciamento, embora essa pr?tica esteja sendo questionada. A NGS pode ser apropriada para diagnosticar dist?rbios gen?ticos suspeitos quando ? improv?vel que o sequenciamento de um ?nico gene forne?a um diagn?stico. Pain?is de genes baseados em NGS s?o usados clinicamente em certas neoplasias hematol?gicas, e os primeiros testes de painel gen?tico para tumores s?lidos. Outras utiliza??es, como o diagn?stico de infec??es e a triagem de pessoas saud?veis continuam sendo investigados.Next Generation Sequencing (NGS) is a type of DNA sequencing technology that uses parallel sequencing of multiple small fragments of DNA. This technology has allowed for a dramatic increase in speed (and a decrease in cost) in which an individual's genome can be sequenced. Sanger sequencing is used to confirm the presence of specific mutations identified by NGS in clinical situations due to the greater accuracy of traditional sequencing methods, although this practice is being questioned. NGS may be appropriate to diagnose suspected genetic disorders when single gene sequencing is unlikely to provide a diagnosis. NGS-based gene panels are used clinically in certain hematological malignancies, and the first genetic panel tests for solid tumors. Other uses, such as the diagnosis of infections and the screening of healthy people, continue to be investigated

Phenotypic redshifts with self-organizing maps: A novel method to characterize redshift distributions of source galaxies for weak lensing

Wide-field imaging surveys such as the Dark Energy Survey (DES) rely on coarse measurements of spectral energy distributions in a few filters to estimate the redshift distribution of source galaxies. In this regime, sample variance, shot noise, and selection effects limit the attainable accuracy of redshift calibration and thus of cosmological constraints. We present a new method to combine wide-field, few-filter measurements with catalogs from deep fields with additional filters and sufficiently low photometric noise to break degeneracies in photometric redshifts. The multi-band deep field is used as an intermediary between wide-field observations and accurate redshifts, greatly reducing sample variance, shot noise, and selection effects. Our implementation of the method uses self-organizing maps to group galaxies into phenotypes based on their observed fluxes, and is tested using a mock DES catalog created from N-body simulations. It yields a typical uncertainty on the mean redshift in each of five tomographic bins for an idealized simulation of the DES Year 3 weak-lensing tomographic analysis of $\sigma_{\Delta z} = 0.007$, which is a 60% improvement compared to the Year 1 analysis. Although the implementation of the method is tailored to DES, its formalism can be applied to other large photometric surveys with a similar observing strategy.Comment: 24 pages, 11 figures; matches version accepted to MNRA

Precipitation of a layered double hydroxide comprising Mg2+ and Al3+ to remove sulphate ions from aqueous solutions.

This work presents an alternative route to remove sulphate ions from aqueous solutions, which is simple and fast, and its efficiency of sulphate removal is slightly influenced by temperature (26 ?C?70 ?C) and pH (4?12). The lowest residual sulphate concentration was about 60 mg L?1, which was observed in continuous experiments using wastewater (26 ?C, pH 6 and initial sulphate concentration of 630 mg L?1). All these outcomes together have not been observed in the current most used processes of sulphate precipitation, i.e. gypsum and ettringite precipitation. Sulphate removal experiments were carried out in the batch and continuous systems using synthetic solutions. In these conditions, about 75% of sulphate ions were removed for an initial ion concentration of 1800 mg L?1. A continuous test was also performed using a wastewater sample in addition to a synthetic solution. The system reached steady-state conditions after four residence times (40 min) in the experiment with synthetic solutions, whereas three residence times (30 min) were necessary for the tests with the wastewater (initial sulphate concentration of 630 mg L?1). In the latter case, the sulphate removal efficiency was approximately 90%. The characterisation of the experimentally precipitated solids was carried out by DRX, FTIR, SEMEDS, elemental analysis and thermal analysis. These techniques showed that, except in pH 4, the sulphate removal process occurred due to the precipitation of a layered double hydroxide, comprising Mg2+ and Al3+ as its metallic ions and nitrate (due to the salts used for precipitation) and sulphate anions occupying its interlayer space
