    Esta pesquisa objetivou estimar a prevalência do marcador do HBV e seus fatores de risco na população masculina carcerária da Penitenciária de Ribeirão Preto - SP, Brasil. De 1.030 presidiários, foram sorteados 333 participantes, os quais foram submetidos à aplicação de um questionário e à coleta de sangue, no período de maio a agosto de 2003. Para diagnóstico de exposição ao HBV foi utilizado o ensaio imunoabsorvente de ligação de enzimas (ELISA) para detecção dos marcadores HBsAg, anti-HBsAg e anti-HBc total. A prevalência total de infecção pelo HBV nos presidiários foi de 19,5% (IC95%: 15,2 - 23,8). A média de idade dos participantes foi de 30,1 anos. Na análise univariada, a infecção pelo HBV esteve associada à idade acima de 30 anos (p<0,001), uso prévio de drogas injetáveis (p<0,001) e compartilhamento de agulhas prévio (p<0,001). Em um modelo multivariado, de regressão logística, a infecção pelo HBV foi associada à idade acima de 30 anos (OR = 3,3: IC95%: 1,8 - 6.1) e uso prévio de droga injetável (OR = 2,7; IC95%: 1.9 - 6.4). Infecção pelo HBV nas prisões representa grave problema de saúde pública, principalmente relacionado à idade acima de 30 anos e uso prévio de drogas injetáveis.This survey aimed to estimate the prevalence of HBV serological markers and risk factors for this infection in male inmates at the Penitentiary of Ribeirão Preto, State of São Paulo, Brazil. Out of 1030 inmates, a simple random sample of 333 participants answered a questionnaire and had blood samples collected, from May to August 2003. Enzyme-linked immunosorbent assay (ELISA) was used to diagnose HBV infection (HBsAg, anti-HBsAg, and total anti-HBc). The overall prevalence for HBV markers in inmates was 19.5% (CI95%: 15.2 - 23.8). The participants' mean age was 30.1 years. In univariate analysis, HBV infection was associated with age > 30 years (p<0.001), previous injecting drug use (p<0.001) and previous sharing of needles (p<0.001). In a logistic regression multivariate model, HBV infection was associated with age > 30 years (OR = 3.3; CI95%: 1.8 - 6.1) and previous injecting drug use (OR = 2.7; CI95%: 1.9 - 6.4). HBV infection on prisons represents a major health problem, mainly associated with age over 30 years and previous injecting drug use

    Hepatitis C virus (HCV) infection has quite high prevalence in the prison system, reaching rates of up to 40%. This survey aimed to estimate the prevalence of HCV infection and evaluate risk factors for this exposure among male inmates at the Ribeirão Preto Prison, State of São Paulo, Brazil, between May and August 2003. A total of 333 participants were interviewed using a standardized questionnaire and underwent immunoenzymatic assaying to investigate anti-HCV. The prevalence of HCV infection among the inmates was 8.7% (95% CI: 5.7-11.7). The participants'mean age was 30.1 years, and the prevalence was predominantly among individuals over 30 years of age. Multivariate analysis showed that the variables that were independently associated with HCV infection were age > 30 years, tattooing, history of previous hepatitis, previous injection drug use and previous needle-sharing.Infecção pelo vírus da hepatite C no sistema prisional apresenta elevada prevalência, chegando a atingir cifras superiores a 40%.

    Poor sensitivity of rapid tests for the detection of antibodies to the hepatitis B virus : implications for field studies

    Get PDF
    Rapid tests (RTs) can be used as an alternative method for the conventional diagnosis of hepatitis B virus (HBV). This study aims to evaluate antibodies to HBsAg (anti-HBs) and antibodies to HBeAg (anti-HBe) RTs under different Brazilian settings. The following three groups were included: GI: viral hepatitis outpatient services; GII: low resource areas; and GIII: crack users and beauticians. Imuno-rápido anti-HBsAg™ and Imuno-rápido anti-HBeAg™ RTs were evaluated and showed specificities greater than 95% in all groups. The sensitivity values to anti-HBs were 50.38%, 51.05% and 46.73% and the sensitivity values to anti-HBe were 76.99%, 10.34% and 11.76% in the GI, GII and GIII groups, respectively. The assays had a low sensitivity and high specificity, which indicated their use for screening in regions endemic for HBV

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

    Get PDF
    One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

    Search for stop and higgsino production using diphoton Higgs boson decays

    Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

    Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

    The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe
