H1N1pdm09 Adjuvanted Vaccination in HIV-Infected Adults: A Randomized Trial of Two Single versus Two Double Doses
Since human immunodeficiency virus (HIV)-infected individuals are at increased risk of severe disease from pandemic influenza A (H1N1pdm09), vaccination was recommended as a prevention strategy. The aim of the present study was to evaluate the safety, immunogenicity and persistence of the immune response after vaccination against pandemic influenza A (H1N1pdm09) with an adjuvanted vaccine in human immunodeficiency virus (HIV)-infected adults using two single and two double doses.Open label, randomized trial to evaluate the immune response following H1N1pdm09 vaccination in HIV-infected participants compared to HIV-negative controls (NCT01155037). HIV-infected participants were randomized to receive 2 single (3.75 µg hemagglutinin) or 2 double (7.5 µg hemagglutinin) doses of the vaccine, 21 days apart. Controls received one dose of the vaccine. The primary endpoint was seroconversion as measured by hemagglutination inhibition assay. Two hundred fifty six HIV-infected participants (129 and 127 randomized to single and double doses, respectively) and 71 HIV-negative controls were enrolled. Among HIV-infected participants, seroconversion increased from 46.7% and 51.7% after the first dose to 77.2% and 83.8% after the second dose of the vaccine using single and double doses, respectively. Participants aged >40 years showed higher seroconversion compared to younger participants. Seroconversion among HIV-infected women and those with nadir CD4<200 cells/mm(3) was significantly higher with double doses. Persistence of protective antibodies six months after vaccination was achieved by 80% and 89.9% of the HIV-infected participants who received single and double doses, respectively.Our results support the recommendation of two double doses of adjuvanted H1N1pdm09 vaccine for HIV-infected individuals, particularly women, and those aged >40 years or with nadir CD4<200 cells/mm(3), to achieve antibody levels that are both higher and more sustained.ClinicalTrials.gov NCT01155037

Avaliação do Ensino de Empreendedorismo entre Estudantes Universitários por meio do Perfil Empreendedor
Entrepreneurship is a socioeconomic phenomenon that has been valued for its influence on the growth and
development of regional and national economies. The main promoter of this phenomenon are entrepreneurs,
subjects endowed with multiple features that make up their profiles. They are dynamic and results oriented,
benefitting from the fruits of their own personal efforts. Entrepreneurial education is highlighted as one of the most
efficient ways to promote an entrepreneurial culture and train new entrepreneurs. However, some difficulty has
been observed in assessing the effectiveness of teaching and learning this subject. The objective of this study was
to analyze, by means of multivariate techniques, an instrument whose function is to measure the learning of
Entrepreneurship, verifying the change in entrepreneur profiles of 407 college students participating or not in an
entrepreneurial training process. The results showed that students who participated in Entrepreneurship
educational training activities showed significant changes in their entrepreneurial profiles. The main contributions
showed growth in the Self-realization, Planner, Innovative and Risks Assumed dimensions
