Objective:This study aimed to analyse the relationship between vitamin D deficiency and the season when the blood sample was obtained from subjects with chronic hepatitis C (CHC) infection.Design:A cross-sectional study was conducted on a representative sample. Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D [25(OH)D] concentration <50 nmol/l, based on the values set forth by the Endocrine Society guideline for higher-risk populations. Seasonality was defined according to solstices and equinoxes. The association of seasonality and clinical/laboratory characteristics with vitamin D deficiency was assessed using a multivariate logistic regression analysis.Setting:NUPAIG Viral Hepatitis Outpatient Clinic of the Universidade Federal de São Paulo – Brazil.Participants:Adult subjects with CHC infection (n 306).Results:The prevalence of vitamin D deficiency was 16 %, whereas the median serum 25(OH)D concentration was 87 (interquartile range, 59; third quartile = 118) nmol/l. Serum concentration was consistently lower in samples collected in spring and winter than in other seasons. In multivariate analysis, vitamin D deficiency was found to be independently associated with male gender, serum albumin concentration and with samples drawn in winter and spring.Conclusions:The findings show not only the relevance to consider season as a factor influencing 25(OH)D concentration but also the need to actively screen for hypovitaminosis D in all patients with CHC infection, especially in females and those with low albumin concentration.

ARTIGO ORIGINALEnfermeiro escolar: a percepção dos professores sobre as atividades desenvolvidas School nurse: teachers' perception of the activities developed Enfermera escolar: percepción de los docentes sobre las actividades desarrolladas ResumoObjetivou-se conhecer a percepção de professores de ensino fundamental e médio de redes públicas e privadas sobre a presença e as ações do enfermeiro escolar. Trata-se de pesquisa de campo, descritiva, transversal de natureza quantitativa, onde foi realizada uma entrevista com professores que atuam no ensino fundamental e médio de instituições de ensino públicas e privadas diversas sobre a percepção dos professores frente o papel do enfermeiro escolar. Resulta-se que a pesquisa mostrou que 100% dos professores acreditam ser importante a presença de um enfermeiro na escola, mesmo que muitos não tiveram a oportunidade de trabalhar com ele. Conclui-se que esse estudo aponta para a importância do enfermeiro escolar, pois através dele conseguimos ter uma longitudinalidade no cuidado, buscando trazer conhecimentos aos estudantes nessa fase da vida, para que reduza as doenças e agravos na vida adulta. Um ponto negativo é a carência de escola que possuem o programa.
