This study evaluated epidemiological factors for HCV infection associated with sharing perforating and cutting instruments among candidates for blood donation (CBD) in the city of Belém, Pará, Brazilian Amazon. Two definitions of HCV infection cases were used: anti-HCV positivity shown by EIA, and HCV-RNA detection by PCR. Infected and uninfected CBD completed a questionnaire about possible risk factors associated with sharing perforating and cutting instruments. The information was evaluated using simple and multiple logistic regressions. Between May and November 2010, 146 (1.1%) persons with anti-HCV antibodies and 106 (0.8%) with HCV-RNA were detected among 13,772 CBD in Belém. Risk factors associated with HCV infection based on the EIA (model 1) and PCR (model 2) results were: use of needles and syringes sterilized at home; shared use of razors at home, sharing of disposable razors in barbershops, beauty salons etc.; and sharing manicure and pedicure material. The models of HCV infection associated with sharing perforating and cutting instruments should be taken into account by local and regional health authorities and by those of other countries with similar cultural practices, in order to provide useful information to guide political and public strategies to control HCV transmission.

Responsividade materna e desenvolvimento sóciocomunicativo de prematuros durante o primeiro ano de vida
(Universidade Federal do Pará, 2014-04-29) CALDAS, Ivete Furtado Ribeiro; CHERMONT, Aurimery Gomes; http://lattes.cnpq.br/4212769913736000; GAROTTI, Marilice Fernandes; http://lattes.cnpq.br/2218504886013525
Premature neonates with birth weight (BW ) ≤ 2500 grams may show deficits arising from neurological damage that alter the sóciocomunicativo development. Early motherinfant interactions premature are important to assess this risk process , observed from changes in nonverbal communication . The quality of maternal responsiveness during these interactions are important for the development of sóciocomunicativas skills in the first year of life . This study examined the relationship between maternal responsiveness and sóciocomunicativo development of premature infants for each group in four stages of development. 18 dyads with gestational age < 36 6/7 weeks and BW ≤ 2500 grams participated . They were divided into three groups , defined according to their maternal and pregnancy characteristics . For data collection a clinical record , sociodemographic interview , scale of social interaction (EIS) and observation protocol mother and child were used. The sessions took place at three, six, nine and twelve months life. All sessions were recorded on video for full backlog of skills and engagement . The results showed that in the group not primiparous Twins (NGP) significant differences were observed in the states of Engagement Person (EP) ( x2 = 11,00, p=0,012) with longer duration at three months ( M = 90,70; SD =16,10 ). And in engagements with the object and person (EOP) were also significant differences (x2=10,35; p=0,01) observed by checking triadic episodes at six months (M=0,13, SD=0,32). Significant positive correlation between engagement with object (EO) at three months and the total score of the Social Interaction Scale (EIS) at six months (0,592; p<0,05) was identified . In NGP group the child's weight at birth was positively correlated with EP (0,812; p< 0,05) and negatively with EO at three months (-0.812; p<0,05 ) . Therefore, the findings show that the quality of interactions, and sociodemographic risk factors interfere with the development of sóciocomunicativas skills of children born preterm.
