RESUMO
BACKGROUND: This study evaluated serum vascular endothelial growth factor (VEGF) concentrations in women with ectopic pregnancy (EP), miscarriage, and normal pregnancy (NP). MATERIALS AND METHODS: This was a case-control study comparing serum VEGF concentrations among 72 women with ectopic pregnancy (n = 35), miscarriage (n = 15), and normal pregnancy (n = 22) matched for gestational age. For the determination of serum VEGF concentration a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) was used. Patients were stratified according to serum VEGF above or below 200 pg/ml. RESULTS: The serum level of VEGF was significantly higher in women with EP (median 211.1 pg/ml; range 5-1,017.0 pg/ml) than in women with normal pregnancy (median 5 pg/ml; range 5-310.6 pg/ml) p < 0.0001. Serum VEGF concentrations did not show any statistically significant difference between women with miscarriage (median 231.9 pg/ml; range 5-813.7 pg/ml) and EP (median 211.1 pg/ml; range 5-1,017.0 pg/ml). When threshold concentrations of serum VEGF level > 200 pg/ml were used, an EP could be distinguished from a normal pregnancy with a sensitivity of 51.4%, a specificity of 90.9%, and a positive predictive value of 90%. Between EP and miscarriage, the sensitivity was 51.4%, specificity 42.8%, and a positive predictive value of 69.2%. CONCLUSIONS: Serum VEGF could not distinguish an EP from a miscarriage. However, serum VEGF concentrations could discriminate a normal intrauterine pregnancy (IUP) from an unviable pregnancy (EP or miscarriage).

UNLABELLED: Partial report, quanti-qualitative of action-research developed in the ward test/ambulatory of a University Hospital, extensive to home; integrating students, teachers and nursing team. OBJECTIVE: to establish standards to integrate hospital/community, seeking the man in the home circle, oppose the recovery/rehabilitation and the integration to work/society, considering the problems in the home/work and put into practice the proposition of the SUDS with extension to the hospital/community actions. Home visits raising the home conditions, family and/or community, consolidating their participation in the process. During the hospital stay nursing care was oriented to conduct the participation and realization of the care by the client and relatives happening the same in the ambulatory probation.
