Abstract: OBJETIVO: Determinar a prevalência do uso pesado de drogas por estudantes de primeiro e segundo graus em uma amostra de escolas públicas e particulares, e identificar fatores demográficos, psicológicos e socioculturais associados. MéTODOS: Trata-se de um estudo transversal com uma técnica de amostragem do tipo intencional comparando-se escolas públicas de áreas periféricas e centrais e escolas particulares. Foi utilizado um questionário an nimo de autopreenchimento. A amostra foi constituída por 2.287 estudantes de primeiro e segundo graus da cidade de Campinas, SP, no ano de 1998. Considerou-se uso pesado, o uso de drogas em 20 dias ou mais nos 30 dias que antecederam a pesquisa. Para análise estatística, utilizou-se a análise de regress o logística polit mica - modelo logito, visando identificar fatores que influenciem este modo de usar drogas. RESULTADOS: O uso pesado de drogas lícitas e ilícitas foi de: álcool (11,9%), tabaco (11,7%), maconha (4,4%), solventes (1,8%), cocaína (1,4%), medicamentos (1,1%), ecstasy (0,7%). O uso pesado foi maior entre os estudantes da escola pública central, do período noturno, que trabalhavam, pertencentes aos níveis socioecon micos A e B, e cuja educa o religiosa na infancia foi pouco intensa. CONCLUS ES: Maior disponibilidade de dinheiro e padr es específicos de socializa o foram identificados como fatores associados ao uso pesado de drogas em estudantes.

Abstract: introduction: many international studies show that religion is an important dimension modulating the use of alcohol and drugs by adolescents. objectives: to determine which religious variables are associated to frequent or heavy use of alcohol, tobacco and drugs among adolescents in intermediate and high schools in campinas, brazil. methods: a cross-sectional study using a self-report anonymous questionnaire was administered to 2.287 students from a convenience sample of seven schools: five from central areas (two public and three private schools) and two public schools from the outskirts of the city, in 1998. the study analyzes data regarding the use of alcohol, tobacco, medicines, solvents, marijuana, cocaine and ecstasy. the religious variables included in the regression analysis were: religious affiliation, church attendance, self-assessed religiousness, and religious education in childhood. for the substances, nicotine, alcohol, marijuana, cocaine, ecstasy and "abuse of medicines" a logistic regression analysis for dicotomic answer was applied. results: the heavy use of at least one drug during the last month was more frequent among students that did not have a religious education during childhood. the use in the last month of cocaine, ecstasy and (abuse of) medicines was more frequent among those students that had no religion (cocaine and medicines) and that did not have a religious education during childhood (ecstasy and medicines). conclusions: this study is consistent with previous investigations demonstrating a strong influence of religious variables over the use of drugs among adolescents. interesting, it was found that no or weaker religious education during childhood was markedly associated with significant more use of drugs during adolescence.

Abstract: Objectives. Using a urethral device at the fossa navicularis, bladder pressure during voiding can be estimated by a minimal invasive technique. This study purposes a new diagnostic index for patients with lower urinary tract symptoms (LUTSs). Methods. Fifty one patients presenting with LUTSs were submitted to a conventional urodynamic and a minimal invasive study. The results obtained through the urethral device and invasive classic urodynamics were compared. The existing bladder outlet obstruction index (BOOI) equation that classifies men with LUTSs was modified to allow minimal invasive measurement of isovolumetric bladder pressure in place of detrusor pressure at maximum urine flow. Accuracy of the new equation for classifying obstruction was then tested in this group of men. Results. The modified equation identified men with obstruction with a positive predictive value of 68% and a negative predictive value of 70%, with an overall accuracy of 70%. Conclusions. The proposed equation can accurately classify over 70% of men without resorting to invasive pressure flow studies. We must now evaluate the usefulness of this classification for the surgical treatment of men with LUTSs. 1. Introduction Invasive pressure flow studies (PFSs) in urodynamics are still the gold standard method for objective classification of bladder outlet obstruction (BOO) in men with lower urinary tract symptoms (LUTSs). It is able to delineate patients for successful surgical approach [1], however, it is still costly, time-consuming, and associated with significant morbidity. The risks of complications after conventional urodynamic study in men with BOO are greater, and acute urinary retention, macroscopic hematuria, urinary tract infection, and/or fever can occur in over 19% of the cases [2]. During the past 14 years, many experts have raised minimal invasive possibilities as substitutes [3, 4]. Griffiths et al. have previously described and validated a minimal invasive technique based on controlled inflation of a penile cuff during voiding [5]. Others had attempted other types of penile cuffs and condoms with insufficient results [3, 6–9]. Trying to overcome these limitations, we developed, in association with the University’s Biomedical Engineering Department, a urethral device capable of extracting from the voiding patient measurements comparable to those achieved from invasive PFS [10]. We have published before that applying logistic regression fitting to the minimal invasive method utilizing this urethral device was able to detect most patients with BOO [10]. However, the

Abstract: Liver Regeneration is clinically of major importance in the setting of liver injury, resection or transplantation. We have demonstrated that the NF-κB inhibitory protein A20 significantly improves recovery of liver function and mass following extended liver resection (LR) in mice. In this study, we explored the Systems Biology modulated by A20 following extended LR in mice.

Abstract: in brazil, the ministry of agriculture, livestock and provision is responsible for regulating specifications, warranties, tolerance thresholds, registration, packing and labeling of substrates for plants. in the ins (normative instruction) n.o 14, 17 and 31 are included the requirements for ph, electrical conductivity (ec), density, water holding capacity (whc10) and humidity. the acceptable deviations are ±0.5 for ph, ±0.3 ds m-1 for ec, ±15% for density, up to -10% w/w for whc and up to +10% for humidity. the aim of this study was to evaluate the ph, ec, density, humidity and whc10, of several substrates for plants, during a six months period of storage, thus, providing technical assistance to brazilian regulations. nine commercial substrates were used, both organic and inorganic. some deviations from the maximum thresholds required by brazilian regulation were observed for ph, ec, whc10 and humidity in 5, 4, 6 and 2 samples, respectively. density showed values within the range permitted by brazilian regulations. whc10 was the variable showing the greatest restriction regarding the brazilian regulation, followed by ph. it is suggested that tolerance should be increased to -15% for whc10 (w/w) and ph value to ±1.0. in addition, producers should reassess the raw materials constituting the substrates or of the storage time.
