PURPOSE: to determine the prevalence of group B Streptococcus (GBS) in pregnant women in the third trimester of pregnancy and explore the factors potentially associated with colonization. METHODS: a sample of 273 pregnant women in the third trimester of pregnancy, from the prenatal care center in Southern Brasil, was investigated. Vaginal and anorectal samples were collected and innoculated in Todd-Hewitt selective broth supplemented with 10 µg/mL colistin and 15 µg/mL nalidixic acid and afterwards cultured on defibrinated sheep blood agar plates. All suspected colonies were submitted to the agglutination test for detection of the specific group B antigen. The Camp test was used for GBS identification in non-hemolytic varieties. Demographic, socioeconomic, reproductive, and clinico-obstetric data were also analyzed. Prevalence ratio (PR) was used as risk measurement. Confidence interval was considered significant at the level of 95% (alpha=0.05). RESULTS: prevalence of Streptococcus (GBS) colonization amounted to 21.6% (59), 9.9% (27) of pregnant women showing positivity in both sites; vaginal site colonization was found in 6.95% (19) of the women and 4.75% (13) of the samples showed positivity only in the anal site. GBS prevalence was slightly higher in pregnant women under 20 years, in those with less schooling and in primiparae and was twice as high among those who did not reported spontaneous abortion, but with no statistical significance. No difference was found in GBS prevalence according to the history of sexually transmittted diseases and tabagism. When analyzed together, the factors detected as potentially associated with colonization by GBS were: primiparae over 30 years (PR=1.55) and women with more than one sexual partner and increased frequency of sexual activity (p<0.05) (55,6 vs 20.5%; p<0.05). No difference regarding prevalence was found to exist in relation to the history of sexually transmitted diseases, previous spontaneous abortion and tabagism. CONCLUSION: these results confirm the need for routine collection for GBS culture from both sites (vaginal and anal) in all pregnant women in the third trimester of pregnancy.

To evaluate the results of induced labor and to determine the main factors associated with intrapartum cesarean section after patients being submitted to this procedure at the Hospital Universitário of the Universidade Federal de Santa Catarina (HU/UFSC, in the Portuguese acronym), Florianópolis, state of Santa Catarina, Brazil.
A retrospective cross-sectional study that included all the pregnancies that resulted in single-fetus births, whose gestational-age was > 22 weeks and that had been submitted to labor induction at the HU/UFSC in the period from 2013 to 2016.
During the proposed period, 1,491 pregnant women were submitted to the labor induction protocol. In 1,264 cases (84.8%), induction resulted in labor, with 830 (65.7%) progressing to vaginal delivery. Gestational age ≥ 41 + 0 weekswas themost common indication for induced labor (55.2%), and vaginal administration of misoprostol was themost commonly usedmethod (72.0%). Among these pregnant women, the cesarean section rate was of 34.3%. Considering the cases of induction failure, the cesarean section rate rose to 44.3%. The factors associated with cesarean section were: previous history of cesarean delivery (PR [prevalence ratio] = 1.48; 95%CI [confidence interval]: 1.51-1.88), fetuses with intrauterine growth restriction (IUGR) (PR = 1.82; 95%CI: 1.32-2.19), Bishop score ≤ 6 (PR = 1.33; 95%CI: 1.01-1.82), and induction time either < 12 hours (PR = 1.44; 95%CI: 1.17-1.66) or > 36 hours (PR = 1.51; 95% CI 1.22-1.92) between the beginning of the induction and the birth.
Labor induction was successful inmost patients. In the cases in which the final outcome was a cesarean section, the most strongly associated factors were: previous history of cesarean delivery, presence of fetuses with IUGR, and either excessively short or excessively long periods of induction.

PURPOSE: To identify the causes of fetal death in the studied population and to measure their contribution in identifying the cause of this outcome. To propose the use of the system Relevant Condition of Death (ReCoDe) in elucidating the causes of fetal death to minimize the number of unknown causes. METHODS: Cross-sectional study related to fetal deaths seen at a specialized academic hospital in the South of Brazil, from January 2000 to December 2009. The data were collected in the death certificates, maternal medical records and the reports of study of fetuses and attachments, and the findings were compared. Data analysis was performed using SPSS version 17.0. RESULTS: Were included 111 fetuses and their respective mothers in this study. The comparison between the diagnostic causes in the pathology and clinical evaluation showed 74 (66.7%) and 73 (65.8%), respectively. Together, they found a potential cause in 48.7% of cases, while 16.2% remained unknown. When analyzing both together with the ReCoDe system, only 9.9% of stillbirths remained as "unclassified." CONCLUSIONS: The proportion of diagnoses in the cause of death among the pathological and clinical evaluation showed no significant difference. When comparing the results of the cause of death suggested by the clinic/pathology with the use of the ReCoDe system, it appears that this tool has helped to clarify the cause by reducing the amount of those that remained without a possible etiology.
