Introduction: Cytomegalovirus (CMV) infection is a matter of concern for blood bank professionals and blood transfusion recipients, especially in cases of transfusions to neonates and immunocompromised patients. Thus, the present study aimed to determine the seroprevalence of CMV IgG and IgM antibodies among blood donors in the City of Lages, in the mountain region of Santa Catarina, southern Brazil, and to investigate possible associations between the socioeconomic characteristics of donors and CMV serological status. Methods: A seroepidemiological cross-sectional study was conducted on 1,045 blood samples from donors that were used in serological screening over a one-year investigation. All the analyses were conducted using the microparticle enzyme immunoassay with Biokit® reagents (Barcelona, Spain), in accordance with the manufacturer's instructions. Results: Anti-CMV IgG seroprevalence in the sample studied was 96.4% (95% CI: 95.23 -97.50) and that of anti-CMV IgM was 2.3% (95% CI: 1.39 -3.20). There were no statistically significant associations between the presence of antibodies and the socioeconomic characteristics of donors. Conclusions: The blood donors in the study region had high seroprevalence of anti-CMV IgG. Thus, blood component screening strategies and careful indication for blood transfusions require special attention among healthcare professionals as part of the actions for prevention and reduction of primary infections caused by CMV.

O tabagismo é um problema de saúde pouco explorado nos bancos de sangue, um dos motivos que objetivou este estudo, para tornar os dados disponíveis a outros pesquisadores, de forma a garantir a realização de novos estudos interdisciplinares sobre a situação transfusional e a qualidade do sangue doado pelo fumante, melhorando a qualidade de vida do doador. O estudo foi realizado mediante uma pesquisa de 3 mil candidatos aptos à doação de sangue no Hemocentro Regional de Lages. Para abordar o tabagismo foi elaborado um questionário que foi inserido na triagem clínica realizada rotineiramente com os candidatos à doação de sangue. Dos 3 mil doadores avaliados na pesquisa, 373 (12,4%) eram fumantes, sendo 66,5% do sexo masculino, 77,2% da cor branca, 57,5% com idade entre 18 a 35 anos. O grau de escolaridade foi o ensino fundamental com 42,1%. Em relação ao número de doações anteriores, 43,1% doaram pela 1ª vez, 56,9% dos doadores eram de repetição. O número de cigarros fumados entre um e cinco por dia foi 30,8% e de seis a dez/dia, 33,2%. Os valores de hematócrito e hemoglobina, comparando grupos não fumantes e fumantes, diferiram significativamente uns dos outros. A prevalência de doadores fumantes verificada neste estudo foi considerada pequena, possivelmente não interferindo na qualidade do sangue, pois o percentual que traz problemas em relação a carboxi-hemoglobina está relacionado aos grandes fumantes, sendo a minoria dos doadores estudados. Faz-se necessário conhecer o perfil do doador fumante nos bancos de sangue do País para poder levar o conhecimento e informações através de campanhas educativas e preventivas.

The aim of this work was to research and analyze questions related to the habit of self-medication among students from Medicine, Engineering, Pedagogy and Law from UNIPLAC. It was verified the prevalent drugs used as selfmedication and if the self-medication was due to the level of stress that the undergraduate course may cause. Also, if students justify the self-medication by the need of help for a good performance in the studies. The study was observational, transversal and descriptive with the participation of 121 students. The instrument to collect data was a closed questionnaire. Most of the participants was females, presenting an age around 28 years old, with familiar income above four minimum salaries. 71% of these students considered their undergraduate course is stressing, being Medicine the most stressing and Law the least one. With respect to the self-medication, from the four undergraduate courses analyzed, Law and Engineering showed the same perceptual of 39% of self-medication while Medicine shows 40% and Pedagogy 63,6%. Vitamins were the most cited medicine used, followed by the anxiolytics and anti-depressives.

The HIV, in hemotheraphy, may be transmitted by erythrocyte, platelets, crioprecipitated, frozen fresh plasma and possibly, by other blood components. Appropriate legislations for this new reality were elaborated normatizing the hemotheraphy practices in Brazil, creating a set of procedures and actions aiming at guaranteeing the quality of the blood, during the whole process. However, the residual risk remains, and it can be calculated as a product of the incidence and period of the immunological window. The objective [corrected] of the present study was to determine the rate of residual risk of the HIV blood transmission, in the blood donors from the Mountain Region of Santa Catarina. In order to calculate the residual risk of the HIV markers, 4,857 donors of repetition from the 24,969 individuals who donated blood from 2000 to 2003 were evaluated, and the results showed a serumconversion, in one case. The method used to calculate the residual risk followed the model of the immunological incidence window used by Schreiber (1996), in the USA. A estimate risk of 1:50,000 was verified. The case was considered as confirmed when one of the HIV, in the Hemocenter, is considered one of the HIV markers, in 1:50.000, which confirms the hypothesis that the new legislation related to the Blood National Politics, with the introduction of more sensible tests is decreasing the immunological window, diminishing the residual and, consequently, intensifying the transfusion security.

Objective: the objective was to trace the epidemiological profile of medical students at the Universidade do Planalto Catarinense (UNIPLAC) in Lages / SC. Method: study of data obtained through a questionnaire applied to 94 students from August 2013 to December 2013. Results: the average age of the participants was 23.06 years, with a minimum of 19 years and a maximum of 39 years. 19.1% were smokers, of these 8.5% were daily smokers and 10.6% were occasional smokers. The average age of smoking initiation was 17.88 years. 22.3% started smoking at 18 years of age. The highest incentive to start using cigarettes was the influence of friends in 61.1%. 72.2% of academic smokers smoked up to 10 cigarettes a day, and 61.1% said they were interested in quitting. 38.9% described pleasure and 33.3% described reducing anxiety as a sensation of smoking exposure. Conclusion: the high prevalence of smokers among medical students shows the need to reinforce prevention and smoking cessation programs aimed at this population.
