Subpopulações e ativação de linfócitos T CD4+ e T CD8+ em crianças e adolescentes HIV positivos vacinados contra Neisseria meningitidis C

Neisseria meningitidis sorogrupo C (MenC) tem sido causador de surtos no Brasil, desde 2005. Vacinas conjugadas contra MenC estão disponíveis desde 1999 nos países desenvolvidos e mais recentemente no Brasil. São vacinas eficazes em pacientes imunologicamente normais, mas pouco se conhece sobre o impacto em pacientes HIV+. O objetivo principal deste estudo foi investigar se há alguma correlação entre a resposta de LT CD4+ de memória e a resposta de anticorpos específicos para o MenC, assim como conhecer as populações de memória dos LT CD8+, em crianças e adolescentes infectados pelo HIV respondedores ou não à vacina MenC conjugada. Amostras de sangue de 36 pacientes HIV+ foram coletadas antes e após imunização, para análises laboratoriais, soros e células coletadas foram congelados e enviados ao nosso laboratório para a análise da resposta imune humoral e celular. Utilizamos o ensaio bactericida para avaliar a resposta humoral e dividir a população de estudo em soroconversor positivo e soroconversor negativo. A citometria de fluxo foi aplicada para identificação das seis subpopulações de LT CD4+ e T CD8+ e avaliação do perfil de ativação. Não encontramos mudanças no perfil de distribuição das subpopulações antes e após a vacinação. A subpopulação LT CD4+ Int correlacionou positivamente com os títulos de anticorpos e a ativação, de um modo geral, estava elevada nos respondedores, conferindo certa importância para essa célula. Semelhanças foram observadas entre as subpopulações LT CD4+ e T CD8+. Em suma, este estudo revelou importantes associações entre a resposta de anticorpos bactericidas após a vacinação, o perfil de distribuição das subpopulações de LT CD4+ LT CD8+ e seu status de ativação.

Design, construction and evaluation of systems to predict risk in obstetrics.

We present a systematic, practical approach to developing risk prediction systems, suitable for use with large databases of medical information. An important part of this approach is a novel feature selection algorithm which uses the area under the receiver operating characteristic (ROC) curve to measure the expected discriminative power of different sets of predictor variables. We describe this algorithm and use it to select variables to predict risk of a specific adverse pregnancy outcome: failure to progress in labour. Neural network, logistic regression and hierarchical Bayesian risk prediction models are constructed, all of which achieve close to the limit of performance attainable on this prediction task. We show that better prediction performance requires more discriminative clinical information rather than improved modelling techniques. It is also shown that better diagnostic criteria in clinical records would greatly assist the development of systems to predict risk in pregnancy.

Process envelopes for stabilisation/solidification of contaminated soil using lime-slag blend.

PURPOSE: Stabilisation/solidification (S/S) has emerged as an efficient and cost-effective technology for the treatment of contaminated soils. However, the performance of S/S-treated soils is governed by several intercorrelated variables, which complicates the optimisation of the treatment process design. Therefore, it is desirable to develop process envelopes, which define the range of operating variables that result in acceptable performance. METHODS: In this work, process envelopes were developed for S/S treatment of contaminated soil with a blend of hydrated lime (hlime) and ground granulated blast furnace slag (GGBS) as the binder (hlime/GGBS = 1:4). A sand contaminated with a mixture of heavy metals and petroleum hydrocarbons was treated with 5%, 10% and 20% binder dosages, at different water contents. The effectiveness of the treatment was assessed using unconfined compressive strength (UCS), permeability, acid neutralisation capacity and contaminant leachability with pH, at set periods. RESULTS: The UCS values obtained after 28 days of treatment were up to ∼800 kPa, which is quite low, and permeability was ∼10(-8) m/s, which is higher than might be required. However, these values might be acceptable in some scenarios. The binder significantly reduced the leachability of cadmium and nickel. With the 20% dosage, both metals met the waste acceptance criteria for inert waste landfill and relevant environmental quality standards. CONCLUSIONS: The results show that greater than 20% dosage would be required to achieve a balance of acceptable mechanical and leaching properties. Overall, the process envelopes for different performance criteria depend on the end-use of the treated material.
