- Abortion: a review of women's perception in relation to their partner's reactions in two Brazilians cities(2014) NONNENMACHER, Daniele; BENUTE, Glaucia Rosana Guerra; NOMURA, Roseli Mieko Yamamoto; AZEVEDO, George Dantas de; DUTRA, Elza Maria do Socorro; REBOUAS, Melina Sefora Souza; LUCI, Mara Cristina Souza de; FRANCISCO, Rossana Pulcineli VieiraObjective: to analyze women's perception in relation to their partner's reaction and behavior during the abortion process in two Brazilian capitals, associating the variables from women who suffered a spontaneous abortion with those from women who induced it. Methods: semi-structured, questionnaire-based interviews were conducted with 285 women who underwent spontaneous abortion and 31 who reported having induced it. The data were analyzed using the thematic analysis technique, and, subsequently, by the IBM SPSS Statistics Standard Edition software program. The significance level was set at p < 0.05. Results: in both capitals, the women who induced an abortion referred to the partner as the person who could not find out about the abortion (p<0.01 in Natal; p = 0.02 in Sao Paulo-SP) and, simultaneously, as the one who could have avoided it (p < 0.01 in Natal; p = 0.03 in Sao Paulo). In Natal-RN, induced abortion was associated with the partner's absence at the time pregnancy was confirmed (p = 0.02) and, in Sao Paulo-SP, with their negative reaction to news of the pregnancy (p = 0.04) and lack of participation in the abortion process (p < 0.01). Conclusion: despite having achieved independence, women still regard male participation in the abortion process as an important factor. The specifics of each capital denote the influence of the geographic and cultural dimension, indicating the need to take into account the particulars of each region in Brazil while considering a holistic approach to women's health.
- Fetal venous circulation in monochorionic twin pregnancies with placental insufficiency: prediction of acidemia at birth or intrauterine fetal death(2014) LIAO, T. B.; NOMURA, R. M. Y.; LIAO, A. W.; FRANCISCO, R. P. V.; ZUGAIB, M.Objectives To investigate fetal venous Doppler measurements in monochorionic twin pregnancies complicated by placental insufficiency and the relationship between fetal venous flow and acidemia at birth or intrauterine fetal death. Methods This was a prospective study of 18 monochorionic twin pregnancies with placental insufficiency. Inclusion criteria were monochorionic-diamniotic twin pregnancy, abnormal umbilical artery (UA) Doppler indices, intact membranes and absence of fetal congenital abnormalities. Cases of twin-to-twin transfusion syndrome were excluded. The following Doppler measurements were studied: UA pulsatility index (PI), ductus venosus PI, middle cerebral artery PI and peak systolic velocity, intra-abdominal umbilical vein (UV) time-averaged maximum velocity (TAMXV) and left portal vein (LPV) TAMXV. Doppler parameters were transformed into Z-scores (SD values from the mean) or multiples of the median according to normative references. Results UA pH<7.20 occurred in nine (25.0%) neonates, pH<7.15 in four (11.1%) and intrauterine death in four (11.1%) fetuses. The UV-TAMXV and LPV-TAMXV Z-scores were significantly lower in the group with pH<7.20 or intrauterine fetal death (-1.79 vs -1.22, P=0.006 and -2.26 vs -1.13, P=0.04, respectively). In cases with pH<7.15 or intrauterine fetal death, UV pulsations were more frequent (50.0% vs 10.7%, P=0.03) and UV-TAMXV Z-score was significantly lower (-1.89 vs -1.26, P=0.003). Mixed effects logistic regression analysis, accounting for the paired nature of the outcomes for the two twins in each pregnancy, demonstrated that the UV-TAMXV Z-score significantly predicted UA pH at birth<7.20 or intrauterine fetal death. TheDoppler parameter that independently predicted pH<7.15 or intrauterine fetal death was presence of pulsation in the UV. Conclusion UV Doppler parameters may predict acidemia at birth or intrauterine fetal death in monochorionic twins complicated by placental insufficiency.
- Transient accelerations of fetal heart rate analyzed by computerized cardiotocography in the third trimester of pregnancy(2014) LAULETTA, Ana Luisa Fernandes; NOMURA, Roseli Mieko Yamamoto; MIYADAHIRA, Seizo; FRANCISCO, Rossana Pulcineli Vieira; ZUGAIB, MarceloObjective: the aim of this study was to investigate the patterns of transient FHR accelerations (10 bpm and 15 bpm) in the third trimester of pregnancy, comparing the occurrence of this event before and after the 32nd gestational week. Methods: This is a prospective study comparing the results of the computerized cardiotocography of 46 low-risk women with singleton pregnancies, maternal age between 18 and 40 years, gestational age between 28 and 40 weeks, absence of maternal morbidity and adequate fetal growth according to ultrasound. Computed Cardiotocography (8002 Sonicaid System and Fetal Care System) was performed for 30 minutes to analyze the variables of FHR. Results: twenty-three pregnant women underwent cardiotocography before 32 weeks (mean = 29.9 weeks, SD = 1.4 weeks) and were compared with 23 pregnant women who were examined after 32 weeks (mean = 36.3 weeks, SD = 2.5 weeks). Regarding the characteristics of FHR, fetuses evaluated between 32 1/7 weeks and 40 weeks showed a significantly greater number of accelerations above 15 bpm (median = 5, variation 0-18) than the group of pregnant women from 28 to 32 weeks (median = 4, variation 0 to 10; P = 0.048). There was a significant positive correlation between the number of accelerations above 15 bpm and the gestational age at examination (rho = 0.33; P = 0.026). Conclusion: computerized cardiotocography showed an association regarding the number of transient accelerations greater than 15 bpm in the assessment of both periods before and after 32 weeks of gestational age, suggesting the influence of the maturation of the fetal autonomic nervous system with pregnancy progression.
