Abstract: objective: to assess the knowledge, attitudes and practices of women related to the pap test and the association between these behaviors and sociodemographic characteristics. methods: a household survey with quantitative approach was conducted. a total of 267 women aged 15 to 69 years, randomly selected in a stratified manner, living in the city of s?o josé de mipibu, northeastern brazil, were interviewed in 2007. a questionnaire consisting of pre-coded open questions was administered and answers were described and analyzed, as for adequacy of knowledge, attitudes, and practices of women regarding the pap test. tests of association were carried out between sociodemographic characteristics and behaviors studied at a 5% significance level. results: although 46.1% of the women interviewed showed adequate knowledge about the pap test, a significantly higher proportion of adequacy was seen regarding attitudes and practices, 63.3% and 64.4%, respectively. higher schooling was associated with adequacy of knowledge, attitudes, and practices. the main barriers to the pap test were negligence, non-requesting by their physicians, and shame. conclusions: the physician is the main source of information about the pap test. however, women who more often attend medical visits, despite their good practice, show low adequacy of knowledge and attitudes related to the pap test, which indicates that they are not receiving appropriate information on the test's purpose, advantages and benefits to women's health.

Abstract: this study assessed the influence of maltreatment or neglect during childhood on preschoolers’ (3 to 6 years of age) attachment representations. the second goal of this article was to explore the relation between child’s gender and attachment representations. the role of a non-abusive relationship with an alternative caregiver (minimizing the effects of maltreatment or neglect) in the child’s attachment system was also investigated. maltreated children (n=20) and neglect children (n=40) were recruited from portuguese child protective services (cypc). the non-maltreated and non-neglected children (n=30) were recruited from a private preschool institution (they attend kindergarten or leisure activities). groups were similar in socio-economic status (ses), age, gender and verbal abilities. abuse status was assessed with an adapted version of the maltreatment and neglect questionnaire (calheiros, 1996). verbal abilities of children were assessed with the “hearing and language” scale of the griffiths scales of mental development (griffiths, 1970). attachment representations were assessed with the attachment story completion task (asct; bretherton, ridgeway, & cassidy, 1990). the stories were coded according to miljkovitch, pierrehumbert, karmaniola, and halfon (2003) q-score methodology. results show that maltreat or neglected preschool children have more insecure (deactivation or hyperactivation) and disorganized attachment representations, and less secure strategies when compared to controls. no differences in attachment representations were found as a function of the child’s gender or as a function of the existence of relationship with a non maltreating or non neglectful adult. results are discussed in terms of attachment theory and future investigation proposals are made.

Abstract: we analyzed cervical specimens of 202 women, aged 15 to 64 years, attended at luis antonio hospital, natal, brazil, to determine the prevalence of hpv and identify the more frequent genotypes and risk factors for hpv infection in women attended at a cervical cancer screening service. two specimens were collected from each patient: one for cytological examination and the other to detect hpv dna by pcr, and typing by dot blot hybridization. a total of 54.5% of the sample had normal cytology and 45.5% had cytological alterations. hpv was detected in 24.5% of the cytologically normal women and in 59.8% of those with altered cytology. both single and double hpv infection increased the likelihood of cytological alterations. thirteen types of hpv were identified, most of which were high risk. hpv 16 was the most prevalent single-type infection, followed by hpv 58. the most frequent double infection was the association between hpv 56 and 57. the prevalence of hpv in cytologically normal women was greater than that reported for countries on all the continents except africa. the inverse was observed in women with cytological alterations. the distribution of hpv types was similar to that described for the americas, with some differences. multiple sexual partners was the only risk factor showing an association with the presence of hpv infection.

Abstract: During septic shock there is increased generation of thrombin, TNF-α and nitric oxide (NO). Human platelets were exposed for 1 hour to the NO donor diethylamine-NONOate (0.5 μM), lipopolysaccharide (LPS; 100 ng/ml), TNF-α (40 ng/ml), or thrombin (5 IU/ml). Microparticles were recovered through filtration and ultracentrifugation and analyzed by electron microscopy, flow cytometry or Western blotting for protein identification. Redox activity was characterized by lucigenin (5 μM) or coelenterazine (5 μM) luminescence and by 4,5-diaminofluorescein (10 mM) and 2',7'-dichlorofluorescein (10 mM) fluorescence. Endothelial cell apoptosis was detected by phosphatidylserine exposure and by measurement of caspase-3 activity with an enzyme-linked immunoassay.Size, morphology, high exposure of the tetraspanins CD9, CD63, and CD81, together with low phosphatidylserine, showed that platelets exposed to NONOate and LPS, but not to TNF-α or thrombin, generate microparticles similar to those recovered from septic patients, and characterize them as exosomes. Luminescence and fluorescence studies, and the use of specific inhibitors, revealed concomitant superoxide and NO generation. Western blots showed the presence of NO synthase II (but not isoforms I or III) and of the NADPH oxidase subunits p22phox, protein disulfide isomerase and Nox. Endothelial cells exposed to the exosomes underwent apoptosis and caspase-3 activation, which were inhibited by NO synthase inhibitors or by a superoxide dismutase mimetic and totally blocked by urate (1 mM), suggesting a role for the peroxynitrite radical. None of these redox properties and proapoptotic effects was evident in microparticles recovered from platelets exposed to thrombin or TNF-α.We showed that, in sepsis, NO and bacterial elements are responsible for type-specific platelet-derived exosome generation. Those exosomes have an active role in vascular signaling as redox-active particles that can induce endothelial cell caspase-3 activation

Abstract: objective: to set up a method for dna extraction from paraffin embedded cervical cancer specimens, previously formalin-fixed, aiming to accomplish retrospective analysis. methods: sixty specimens were submitted to dna extraction by three different methods. all of them involved digestion of the tissues by proteinase k, followed by dna purification, based in three different approaches: protocol a used a dna isolation kit, glassmax (gibco/brl); protocol b was performed with the kit gfxtm amersham pharmacia biotech; and protocol c was based on the method proposed by banerjee et al.(2), with modifications. to evaluate the integrity and sufficiency of the dna, the samples were submitted to a in vitro amplification of a segment of the human b-globin gene, and the pcr products were analyzed by electrophoresis on 7% polyacrylamide gels, followed by silver staining. results: among 60 analyzed samples, 45 showed positive results when submitted to the three protocols. in six samples, pcr fragments were obtained with dnas extracted through protocols a e c; in three samples, dna extraction was achieved with protocol a only; and in two samples the dna was successfully extracted only through protocol c. conclusions: protocols a and c generated similar results. although protocol c is more labor-intensive and time consuming, it does not require a commercial kit and therefore has a lower cost. furthermore, it does not require the use of organic solvents and may be considered a good alternative for dna extraction from paraffin embedded tissues.
A nova lei de drogas e seus dilemas: apontamentos para o estudo das formas de desigualdade presentes nos interstícios do ordenamento jurídico-penal brasileiro = The new law of drugs and its dilemmas: studying forms of inequalities within the interstices of the Brazilian legal-criminal order

Abstract: De acordo com a assim chamada Nova Lei de Drogas (Lei 11. 343/06) – que aboliu a pena de pris o para usuários de drogas flagrados neste delito – difundiu-se na opini o pública, ao menos no primeiro momento, a idéia de que o ordenamento jurídico-penal brasileiro estaria caminhando para formas menos conservadoras de lidar com esta complexa quest o. Contudo, o que pesquisadores que se dedicam ao tema têm tido a oportunidade de notar é que essa lei acabou implicando em um aval para que tais casos continuassem – como sempre foram – resolvidos, como se diz, na rua. E neste particular, dependendo da origem social (digamos assim) de quem é surpreendido usando drogas (e n o da Lei), o tratamento dado pelos policiais poderia ir da extors o (no caso de usuários de classe média) à aplica o de castigos físicos e morais (em se tratando de pessoas pobres ou favelados).
