Tudo o que vem à rede é peixe? A credibilidade da informação na web

O objetivo deste estudo é conhecer uma vertente específica do perfil informacional dos alunos que cresceram na era digital, ditos nativos digitais, na utilização que fazem da Internet. Assim, pretende-se aferir os critérios que aplicam na avaliação das fontes de informação disponíveis na web na vertente da credibilidade. A análise dos dados obtidos, resultantes da aplicação de 195 questionários a alunos do 8º ao 12º, é enquadrada e sustentada por revisão da literatura acerca do conceito de credibilidade da informação.

Molecular detection of HPV 16 and 18 in cervical samples of patients from Belo Horizonte, Minas Gerais, Brazil

PURPOSE: The aim of this study was to investigate the frequency of HPV infection and the types 16 and 18 in cervical samples from patients attended at two public health services of the city of Belo Horizonte, MG. METHODS: Cervical samples from 174 patients were collected for cytopathological and molecular tests. HPV infection was searched by PCR utilizing MY09 and MY11 primers or HPV 16 and HPV 18 specific primers. RESULTS: Amongst the 174 samples analyzed, 20.7% presented squamous intraepithelial and/or invasive lesions detected on cytopathological analysis and of those, 94.4% were infected by HPV. HPV 16 was found in 20% of the cases of low-grade squamous intraepithelial lesions and in 40% and 50% of high-grade squamous intraepithelial lesion and squamous invasive carcinoma, respectively. HPV 18 was detected in 6.7% of the low-grade lesion samples and in two HPV16 co-infected samples. In 50% of the cases of high-grade lesion, the HPV type was not determined. CONCLUSION: The HPV 16 was the virus type more frequently detected. However, more than 50% of the positive samples at the cytopathological analysis were negative for HPV 16 and 18, indicating that possibly other virus types are present in relative high frequencies in the studied population.

A Publicidade no Ensino do Inglês no 1.º Ciclo: uma abordagem didática

Numa era de globalização, de desenvolvimento tecnológico exponencial e de consumismo exacerbado, a publicidade conquistou o quotidiano das sociedades modernas e seduziu, também, as nossas crianças. Subjacente ao paradigma de que o comportamento humano dá respostas favoráveis a estímulos adequados e apresentados com oportunidade e habilidade (Caetano et al., 2011), colocamos a hipótese de utilização didática de anúncios publicitários na aula de Inglês para o desenvolvimento de competências comunicativas. Este projeto assentou no aproveitamento do potencial que a publicidade oferece, tendo em conta, por um lado, a envolvência sedutora que a torna um meio privilegiado para captar a atenção e veicular informação e, por outro, a prevalência de palavras em Inglês que nela se observa. O estudo, de natureza qualitativa, é o resultado de uma investigação-ação, na qual adotamos uma metodologia baseada num modelo descritivo e interpretativo, através de métodos qualitativos de recolha de dados e análise de informação, que teve como participantes crianças do 4.º ano de escolaridade. Desenvolvemos questionários, como instrumentos de recolha de dados, aplicados a professores e alunos. Construímos, igualmente, guiões de atividades com sugestões de exploração da publicidade no ensino da língua. Comprovamos que a publicidade, aliada ao Inglês, pode ser um valioso recurso no desenvolvimento e aprendizagem das crianças, pois é um material autêntico, motivador, atrai a atenção, possibilita o contacto com situações reais, envolve linguagem verbal e não-verbal e permite a exploração de diferentes temas, o que contribui, certamente, para a compreensão intercultural, a mobilização de saberes e o desenvolvimento do espírito crítico.

Circulation of human papillomavirus (HPV) genotypes in women from Córdoba, Argentina, with squamous intraepithelial lesions

Human papillomavirus (HPV) can induce a wide spectrum of squamous intraepithelial lesions (SIL) of varying severity. The aim of the present study was to establish the frequency of HPV infection and identify the genotypes circulating in women from Córdoba, Argentina, in relation to age and cytology. A total of 186 women, between 18 and 65 years old, with antecedents of SIL, underwent a pelvic examination and had cervical cells collected for cytology and HPV DNA detection. Ninety-six samples (51.6%) were positive for HPV detection, and sixty-three (65.6%) of them showed the presence of at least one HR-HPV. Low- and high-grade SIL showed significant association in patients younger than 35 years of age. We found 18 different genotypes, with a greater presence of HR-HPV. Genotypes 16 and 6 were the most frequent. Seven (7.3%) multiple infections, 85.7% of which had at least one HR-HPV, were detected. The detection of a large number of different HPV genotypes is a warning sign. It is thus necessary to strengthen the monitoring of the circulation of high-risk genotypes, currently less prevalent in intraepithelial lesions, as a control measure for the possible impact of the implementation of vaccines against genotypes 16 and 18.

A Pilot Cost-Effectiveness Analysis of Treatments in Newly Diagnosed High-Grade Gliomas: The Example of 5-Aminolevulinic Acid Compared With White-Light Surgery

BACKGROUND: High-grade gliomas are aggressive, incurable tumors characterized by extensive diffuse invasion of the normal brain parenchyma. Novel therapies at best prolong survival; their costs are formidable and benefit is marginal. Economic restrictions thus require knowledge of the cost-effectiveness of treatments. Here, we show the cost-effectiveness of enhanced resections in malignant glioma surgery using a well-characterized tool for intraoperative tumor visualization, 5-aminolevulinic acid (5-ALA). OBJECTIVE: To evaluate the cost-effectiveness of 5-ALA fluorescence-guided neurosurgery compared with white-light surgery in adult patients with newly diagnosed high-grade glioma, adopting the perspective of the Portuguese National Health Service. METHODS: We used a Markov model (cohort simulation). Transition probabilities were estimated with the use of data from 1 randomized clinical trial and 1 noninterventional prospective study. Utility values and resource use were obtained from published literature and expert opinion. Unit costs were taken from official Portuguese reimbursement lists (2012 values). The health outcomes considered were quality-adjusted life-years, lifeyears, and progression-free life-years. Extensive 1-way and probabilistic sensitivity analyses were performed. RESULTS: The incremental cost-effectiveness ratios are below €10 000 in all evaluated outcomes, being around €9100 per quality-adjusted life-year gained, €6700 per life-year gained, and €8800 per progression-free life-year gained. The probability of 5-ALA fluorescence-guided surgery cost-effectiveness at a threshold of €20000 is 96.0% for quality-adjusted life-year, 99.6% for life-year, and 98.8% for progression-free life-year. CONCLUSION: 5-ALA fluorescence-guided surgery appears to be cost-effective in newly diagnosed high-grade gliomas compared with white-light surgery. This example demonstrates cost-effectiveness analyses for malignant glioma surgery to be feasible on the basis of existing data.
