Beverage preferences and associated drinking patterns, consequences and other substance use behaviours.

BACKGROUND: Studies about beverage preferences in a country in which wine drinking is relatively widespread (like Switzerland) are scarce. Therefore, the main aims of the present study were to examine the associations between beverage preferences and drinking patterns, alcohol-related consequences and the use of other substances among Swiss young men. METHODS: The analytical sample consisted of 5399 Swiss men who participated in the Cohort Study on Substance Use Risk Factors (C-SURF) and had been drinking alcohol over the preceding 12 months. Logistic regression analyses were conducted to study the associations between preference for a particular beverage and (i) drinking patterns, (ii) negative alcohol-related consequences and (iii) the (at-risk) use of cigarettes, cannabis and other illicit drugs. RESULTS: Preference for beer was associated with risky drinking patterns and, comparable with a preference for strong alcohol, with the use of illicit substances (cannabis and other illicit drugs). In contrast, a preference for wine was associated with low-risk alcohol consumption and a reduced likelihood of experiencing at least four negative alcohol-related consequences or of daily cigarette smoking. Furthermore, the likelihood of negative outcomes (alcohol-related consequences; use of other substances) increased among people with risky drinking behaviours, independent of beverage preference. CONCLUSIONS: In our survey, beer preference was associated with risky drinking patterns and illicit drug use. Alcohol polices to prevent large quantities of alcohol consumption, especially of cheaper spirits like beer, should be considered to reduce total alcohol consumption and the negative consequences associated with these beverage types.

HLA Class I alleles associated with HCV polymorphisms and response to antiviral therapy in HCV genotype 1-infected patients

Aims: The adaptive immune response against hepatitis C virus (HCV) is significantly shaped by the host's composition of HLA alleles. Thus, the HLA phenotype is a critical determinant of viral evolution during adaptive immune pressure. Potential associations of HLA class I alleles with polymorphisms of HCV immune escape variants are largely unknown. Methods: Direct sequence analysis of the genes encoding the HCV proteins E2, NS3 and NS5B in a cohort of 159 patients with chronic HCV genotype 1 infection who were treated with pegylated interferon-alfa 2b and ribavirin in a prospective controlled trial for 48 weeks was exhibited. HLA class I genotyping was performed by strand-specific reverse hybridization with the INNO-LiPA line probe assays for HLA-A and HLA-B and by strand-specific PCR-SSP. We analyzed each amino acid position of HCV proteins using an extension of Fisher's exact test for associations with HLA alleles. In addition, associations of specific HLA alleles with inflammatory activity, liver fibrosis, HCV RNA viral load and virologic treatment outcome were investigated. Results: Separate analyses of HCV subtype 1a and 1b isolates revealed substantially different patterns of HLA-restricted polymorphisms between subtypes. Only one polymorphism within NS5B (V2758x) was significantly associated with HLA B*15 in HCV genotype 1b infected patients (adjusted p=0,048). However, a number of HLA class I-restricted polymorphisms within novel putative HCV CD8+ T cell epitopes (genotype 1a: HLA-A*11 GTRTIASPK1086-1094 [NS3], HLA-B*07 WPAPQGARSL1111-1120 [NS3]; genotype 1b: HLA-A*24 HYAPRPCGI488-496 [E2], HLA-B*44 GENETDVLL530-538 [E2], HLA-B*15 RVFTEAMTRY2757-2766 [NS5B]) were observed with high predicted epitope binding scores assessed by the web-based software SYFPEITHI (>21). Most of the identified putative epitopes were overlapping with already otherwise published epitopes, indicating a high immunogenicity of the accordant HCV protein region. In addition, certain HLA class I alleles were associated with inflammatory activity, stage of liver fibrosis, and sustained virologic response to antiviral therapy. Conclusions: HLA class I restricted HCV sequence polymorphisms are rare. HCV polymorphisms identified within putative HCV CD8+ T cell epitopes in the present study differ in their genomic distribution between genotype 1a and 1b isolates, implying divergent adaptation to the host's immune pressure on the HCV subtype level.

The impact of fibrosis and steatosis on early viral kinetics in HCV genotype 1-infected patients treated with Peg-IFN-alfa-2a and ribavirin.

Summary.  Hepatitis C viral (HCV) kinetics after initiation of interferon-based therapy provide valuable insights for understanding virus pathogenesis, evaluating treatment antiviral effectiveness and predicting treatment outcome. Adverse effects of liver fibrosis and steatosis on sustained virological response have been frequently reported, yet their impacts on the early viral kinetics remain unclear. In this study, associations between histology status and early viral kinetics were assessed in 149 HCV genotype 1-infected patients treated with pegylated interferon alfa-2a and ribavirin (DITTO trial). In multivariate analyses adjusted for critical factors such as IL28B genotype and baseline viral load, presence of significant fibrosis (Ishak stage > 2) was found to independently reduce the odds of achieving an initial reduction (calculated from day 0 to day 4) in HCV RNA of ≥2 logIU/mL (adjusted OR 0.03, P = 0.004) but was not associated with the second-phase slope of viral decline (calculated from day 8 to day 29). On the contrary, presence of liver steatosis was an independent risk factor for not having a rapid second-phase slope, that is, ≥0.3 logIU/mL/week (adjusted OR 0.22, P = 0.012) but was not associated with the first-phase decline. Viral kinetic modelling theory suggests that significant fibrosis primarily impairs the treatment antiviral effectiveness in blocking viral production by infected cells, whereas the presence of steatosis is associated with a lower net loss of infected cells. Further studies will be necessary to identify the biological mechanisms underlain by these findings.

Avaliação da Cultura Organizacional e Liderança – O Caso do Instituto Nacional de Providência Social – Empresa Pública

Ao longo dos últimos anos, com às crescentes mudanças no mundo empresarial, tanto no meio académico, quanto no meio profissional, as relações entre a cultura organizacional e a liderança têm atraído considerável atenção e alguns estudos da área têm apontado a interdependência entre ambos (Schein, 1992; Bass & Avolio, 1993). O presente trabalho de investigação científica, tem por objectivo, avaliar a existência dessa mesma relação através de um estudo de caso, aplicado aos trabalhadores e três gestores, a uma empresa pública de segurança social, cabo-verdiana – Instituto Nacional de Previdência Social – INPS, nos anos 2000 a 2010. A metodologia, consistiu primeiramente numa pesquisa bibliográfica, exploratória e descritiva e ainda foi feito um estudo de caso à empresa. Para a recolha dos dados, foram aplicados questionários com perguntas fechadas aos trabalhadores e gestores com o consentimento do Conselho de Administração. Para a análise dos dados foram utilizadas técnicas quantitativas e qualitativas, feito através das respostas obtidas dos questionários. Com os resultados da pesquisa, conclui-se que a pergunta de partida foi respondida através dos 94% da população inquirida que confirmaram a existência da relação entre a cultura organizacional e liderança e a sua influência dentro da organização. The existent relationship between the organizational culture and the leadership in social safety sector. Along of the last years, with the growing changes in the business world as in the academic middle as in the professional middle, the relation between organizational culture and the leadership have attracted considerable attention and some studies of the area have been pointed the interdependence between both (Schein,1992;Bass Avolio,1993). The present scientific investigation work has the purpose to evaluate the existence of that same relationship through a study of case, applied to the workers and three managers, to a public company of social safety, capverdean-National Institute of Social Precaution-INPS, in years 2000 and 2003. The methodology constitutes firstly in a small one bibliographical, exploratory and descriptive and it was still made a study of case to the company. For it collects of data were applied questionnaires with closed questions to the workers and the three managers with the consent of the Council of Administration. For the analysis of the data quantitative and qualitative techniques were used, done through the obtained answers of the questionnaires. With the results of the research, it is ended that the question of departure was answered through the 94% of the population inquired that confirm the relationship existence between the organizational culture and the leadership and its influence inside of the organization.

A genome-wide approach accounting for body mass index identifies genetic variants influencing fasting glycemic traits and insulin resistance.

Recent genome-wide association studies have described many loci implicated in type 2 diabetes (T2D) pathophysiology and β-cell dysfunction but have contributed little to the understanding of the genetic basis of insulin resistance. We hypothesized that genes implicated in insulin resistance pathways might be uncovered by accounting for differences in body mass index (BMI) and potential interactions between BMI and genetic variants. We applied a joint meta-analysis approach to test associations with fasting insulin and glucose on a genome-wide scale. We present six previously unknown loci associated with fasting insulin at P < 5 × 10(-8) in combined discovery and follow-up analyses of 52 studies comprising up to 96,496 non-diabetic individuals. Risk variants were associated with higher triglyceride and lower high-density lipoprotein (HDL) cholesterol levels, suggesting a role for these loci in insulin resistance pathways. The discovery of these loci will aid further characterization of the role of insulin resistance in T2D pathophysiology.

An analysis of the accounting principles applied by the European Farm Accountancy Data Network

In spite of its relative importance in the economy of many countriesand its growing interrelationships with other sectors, agriculture has traditionally been excluded from accounting standards. Nevertheless, to support its Common Agricultural Policy, for years the European Commission has been making an effort to obtain standardized information on the financial performance and condition of farms. Through the Farm Accountancy Data Network (FADN), every year data are gathered from a rotating sample of 60.000 professional farms across all member states. FADN data collection is not structured as an accounting cycle but as an extensive questionnaire. This questionnaire refers to assets, liabilities, revenues and expenses, and seems to try to obtain a "true and fair view" of the financial performance and condition of the farms it surveys. However, the definitions used in the questionnaire and the way data is aggregated often appear flawed from an accounting perspective. The objective of this paper is to contrast the accounting principles implicit in the FADN questionnaire with generally accepted accounting principles, particularly those found in the IVth Directive of the European Union, on the one hand, and those recently proposed by the International Accounting Standards Committee’s Steering Committeeon Agriculture in its Draft Statement of Principles, on the other hand. There are two reasons why this is useful. First, it allows to make suggestions how the information provided by FADN could be more in accordance with the accepted accounting framework, and become a more valuable tool for policy makers, farmers, and other stakeholders. Second, it helps assessing the suitability of FADN to become the starting point for a European accounting standard on agriculture.

Further insights on the French WISC-IV factor structure through Bayesian structural equation modeling

The interpretation of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is based on a 4-factor model, which is only partially compatible with the mainstream Cattell-Horn-Carroll (CHC) model of intelligence measurement. The structure of cognitive batteries is frequently analyzed via exploratory factor analysis and/or confirmatory factor analysis. With classical confirmatory factor analysis, almost all crossloadings between latent variables and measures are fixed to zero in order to allow the model to be identified. However, inappropriate zero cross-loadings can contribute to poor model fit, distorted factors, and biased factor correlations; most important, they do not necessarily faithfully reflect theory. To deal with these methodological and theoretical limitations, we used a new statistical approach, Bayesian structural equation modeling (BSEM), among a sample of 249 French-speaking Swiss children (8-12 years). With BSEM, zero-fixed cross-loadings between latent variables and measures are replaced by approximate zeros, based on informative, small-variance priors. Results indicated that a direct hierarchical CHC-based model with 5 factors plus a general intelligence factor better represented the structure of the WISC-IV than did the 4-factor structure and the higher order models. Because a direct hierarchical CHC model was more adequate, it was concluded that the general factor should be considered as a breadth rather than a superordinate factor. Because it was possible for us to estimate the influence of each of the latent variables on the 15 subtest scores, BSEM allowed improvement of the understanding of the structure of intelligence tests and the clinical interpretation of the subtest scores.

Condiciones físicas del mar peruano de Tambo de Mora a Paita, durante agosto y setiembre de 1995

Dan a conocer las condiciones oceanográficas registradas durante el Crucero de Evaluación de la Biomasa Desovante de Anchoveta y Sardina BIC Humboldt 9508-09; se describen las condiciones del ambiente físico durante los meses de agosto y setiembre de 1995 y se comparan con observaciones durante el mismo período en los años 1990 y 1994. Las características térmicas superficiales se presentaron dentro de su rango de normalidad para la época, con una tendencia a condiciones ligeramente frías para los próximos meses. La temperatura superficial del mar osciló de 15,0 a 20,5 °C (a 60 mn frente a Paita). La distribución de las anomalías térmicas, se presentó con valores que fluctuaron de +1,0 °C (100 mn frente a Callao) a -2,3° C (a 60 mn frente a Paita). En general, la zona costera tuvo predominio de anomalías negativas. En toda la región prospectada, la salinidad superficial del mar mostró características de las aguas costeras frías dentro de las 20 mn de la costa, observándose una fuerte advección de aguas subtropicales superficiales (ASS) de Chancay y a Casma. La estructura vertical termohalina mostró característica normales en las áreas cercanas a la costa y casi normales fuera de las 30 millas por efecto de la influencia de las ASS con una columna de agua estable y una termoclina casi superficial.

Quetiapine and norquetiapine in plasma and cerebrospinal fluid of schizophrenic patients treated with quetiapine: correlations to clinical outcome and HVA, 5-HIAA, and MHPG in CSF.

This study investigated concentrations of quetiapine and norquetiapine in plasma and cerebrospinal fluid (CSF) in 22 schizophrenic patients after 4-week treatment with quetiapine (600 mg/d), which was preceded by a 3-week washout period. Blood and CSF samples were obtained on days 1 and 28, and CSF levels of homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and 3-methoxy-4-hydroxyphenylglycol (MHPG) concentrations were measured at baseline and after 4 weeks of quetiapine, allowing calculations of differences in HVA (ΔHVA), 5-HIAA (Δ5-HIAA), and MHPG (ΔMHPG) concentrations. Patients were assessed clinically, using the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression Scale at baseline and then at weekly intervals. Plasma levels of quetiapine and norquetiapine were 1110 ± 608 and 444 ± 226 ng/mL, and the corresponding CSF levels were 29 ± 18 and 5 ± 2 ng/mL, respectively. After the treatment, the levels of HVA, 5-HIAA, and MHPG were increased by 33%, 35%, and 33%, respectively (P < 0.001). A negative correlation was found between the decrease in PANSS positive subscale scores and CSF ΔHVA (r(rho) = -0.690, P < 0.01), and the decrease in PANSS negative subscale scores both with CSF Δ5-HIAA (r(rho) = -0.619, P = 0.02) and ΔMHPG (r(rho) = -0.484, P = 0.038). Because, unfortunately, schizophrenic patients experience relapses even with the best available treatments, monitoring of CSF drug and metabolite levels might prove to be useful in tailoring individually adjusted treatments.

A presente memória inscreve-se no âmbito do curso de Licenciatura em Economia e Gestão, variante Banca e Seguros na Universidade Jean Piaget de Cabo Verde. O seu objectivo é analisar a percepção dos estudantes sobre a educação financeira, tendo como público-alvo os estudantes da Escola Secundária Manuel Lopes. Num momento em que a crise económica e financeira assola vários países, sente-se cada vez mais a necessidade de uma melhor gestão das riquezas. Os programas dos vários Governos de Cabo Verde têm focalizado a sua atenção na área económica, descurando de alguma forma a intervenção de outros sectores. O debate sobre a educação financeira deverá ser premente, constituindo-se num desafio e novo paradigma em Cabo Verde. O desenvolvimento deste trabalho científico integra-se num quadro metodológico em que se incidiu sobre a abordagem quantitativa e exploratória, aplicando o inquérito por questionário. Para o efeito, e com base num erro amostral de 7,3% e 95% de confiança, extraiu-se uma amostra de 128 sujeitos de uma população de 440 estudantes do 3º ciclo (11º e 12º anos de escolaridade) da Escola Secundária Manuel Lopes, sita na cidade da Praia, o que se enquadra perfeitamente com os procedimentos de estudo de caso. A amostragem foi probabilística e o método de selecção recaiu sobre as técnicas de amostragem estratificada proporcional. Os dados foram tratados no programa Statístical Package for the Social Science (SPSS), versão 19.0. A análise dos resultados baseou-se na produção e interpretação dos resultados das tabelas, dos gráficos e da aplicação dos testes estatísticos. Os resultados obtidos revelam que os estudantes da Escola Secundária Manuel Lopes inquiridos trabalho têm uma percepção suficiente sobre a educação financeira. Entretanto, ainda existem dúvidas, que podem ser reduzidas e/ou sanadas, por forma a ter o impacto na melhoria da gestão de riquezas da nova geração. Quase a totalidade dos estudantes abrangidos neste estudo consideram que é importante que este tema ser abordado no processo de ensino e aprendizagem. Consideram ainda que os seus professores precisam conhecer melhor estes assuntos.

Spatial and temporal dynamics of drosophilid larval assemblages associated to fruits

The study of organisms and their resources is critical to further understanding population dynamics in space and time. Although drosophilids have been widely used as biological models, their relationship with breeding and feeding sites has received little attention. Here, we investigate drosophilids breeding in fruits in the Brazilian Savanna, in two contrasting vegetation types, throughout 16 months. Specifically, larval assemblages were compared between savannas and forests, as well as between rainy and dry seasons. The relationships between resource availability and drosophilid abundance and richness were also tested. The community (4,022 drosophilids of 23 species and 2,496 fruits of 57 plant taxa) varied widely in space and time. Drosophilid assemblages experienced a strong bottleneck during the dry season, decreasing to only 0.5% of the abundance of the rainy season. Additionally, savannas displayed lower richness and higher abundance than the forests, and were dominated by exotic species. Both differences in larval assemblages throughout the year and between savannas and gallery forests are consistent with those previously seen in adults. Although the causes of this dynamic are clearly multifactorial, resource availability (richness and abundance of rotten fruits) was a good predictor of the fly assemblage structure.
