To evaluate the obstetric and sociodemographic characteristics of gestational diabetic women who maintained hyperglycemia in the postpartum period (6-12 weeks postpartum).
This is a longitudinal cohort study with women who have had gestational diabetes and/or macrosomic children between March 1st, 2016 and March 1st, 2017. Between 6 and 12 weeks after birth, women who had gestational diabetes collected fasting glycemia, glucose tolerance test, and glycated hemoglobin results. The data were collected from medical records and during an interview in the first postpartum consultation. A statistical analysis was performed using frequency, percentage, Chi- Squared test, Fisher exact test, Mann-Whitney test, and multivariate Poisson regression. The significance level adopted for the statistical tests was 5%.
One hundred and twenty-two women were included. Most of the women were younger than 35 years old (70.5%), white, multiparous, and with no history of gestational diabetes. Thirteen percent of the participants developed persistent hyperglycemia. A univariate analysis showed that maternal age above 35 years, being overweight, having grade 1 obesity and weight gain under 5 kg was related to the persistence of hyperglycemia in the postpartum period.
Maternal age above 35 years, obesity and overweight, and the diagnosis of gestational diabetes in the first trimester of pregnancy are associated with hyperglycemia during the postpartum period.

PURPOSE: to describe adverse perinatal outcomes in patients with fetal blood flow centralization, using the relationship between the pulsatility indexes of the middle cerebral and umbilical arteries (MCAPI/UAPI), and between the resistance indexes of the middle cerebral and umbilical arteries (MCARI/UARI), as well as to compare both diagnostic indexes. METHODS: 151 pregnant women with diagnosis of blood flow centralization, attended to at the maternity hospital of Universidade Estadual de Campinas, whose delivery occurred up to 15 days after the ultrasonographic diagnosis, were included. It was considered as adverse perinatal outcomes: Apgar index lower than 7 at the fifth minute, permanence in neonatal ICU, small fetus for the gestational age, severe fetal suffering, perinatal death, hypoglycemia, polycythemia, necrotizing enterocolitis, brain hemorrhage, lung hemorrhage, anemia, septicemia, hyaline membrane disease, convulsive syndromes, hyperreflexia syndrome and kidney insufficiency. Rates of the perinatal adverse outcomes (PAO) for the brain-placentary ratios have been compared, using Fisher's exact or Pearson's χ2 tests, at 5% significance level. Adverse perinatal outcomes according to the gestational age have been evaluated using the Cochrane-Armitage test for trend. RESULTS: the adverse perinatal outcomes for the group with the two indexes altered were: 62.5% of the newborns needed to be placed in an ICU, 75.2% were small for the gestational age (SGA), 35.3% were under severe fetal suffering, 84.4% had hypoglycemia, 8.3% polycythemia, 4.2% necrotizing enterocolitis, and 2.1% brain hemorrhage. There has been significant association between the MCAPI/UAPI and MCARI/UARI ratios along the gestational age, and the need for neonatal intensive care, small fetuses for the gestational age, septicemia, necrotizing enterocolitis, kidney insufficiency, hyaline membrane disease, and anemia. There has been no significant difference between the two indexes of adverse perinatal outcome.

PURPOSE: to diagnose and treat diabetic pregnant women with antiphospholipid antibodies and to describe the gestational and perinatal results. METHODS: we evaluated 56 gestational and pregestational diabetic women who were attended at one specialized prenatal care unit, between July 2003 and March 2004. All of them had a blood test to quantify antiphospholipid antibodies. If positive, they were treated with heparin and aspirin at low doses and the usual treatment for diabetes. We calculated the prevalence and 95% confidence interval for all and also those for the pregestational ones. The characteristics of the pregnancies and the newborns are described. RESULTS: antiphospholipid antibodies prevalence among the diabetic pregnant women was 7% (95% CI - 0.1 to 13.9). Among pregestational diabetic women it was 12% (95% CI - 0.2 to 23.3). Among the diabetic women with antiphospholipid antibodies the duration of disease was five years or more. Maternal age in positive antiphospholipid antibodies diabetics ranged from 27 to 38 years; one was primiparous, another was secundiparous and two were multiparous. CONCLUSION: antiphospholipid antibodies prevalence in diabetic pregnant women was similar to that in the general population and lower than that of the pregestational diabetic women.

Purpose: to identify and investigate the causes of maternal death that occurred in Campinas from 1992 to 1994. Methods: a total of 204 death certificates (DC) whose causes of death were maternal (declared and/or presumed) were selected among the 1032 DC's of 10 to 49 year-old women. A complementary investigation was performed consulting hospital records, Death Survey Units, and households. Results: a total of 20 maternal deaths were confirmed, corresponding to a maternal mortality ratio of 42.2 deaths per 100,000 live births. The direct obstetrical causes were responsible for 85% of the deaths (17 cases). Abortion complications were the main causes of death (7 cases), followed by hemorrhage (4 cases), preeclampsia (3 cases) and puerperal infection (3 cases). Conclusions: despite the apparent progress concerning the reduction in deaths due to hypertensive syndromes during pregnancy, that were the main causes in earlier periods, there was no improvement in the maternal mortality ratio for this studied period. Unfortunately, this lack of progress was due to abortion complications. A better coverage and efficiency of family planning programs, besides the need for implementation of a real epidemiological surveillance of maternal deaths, as well as a better social protection of the pregnant woman, the mother, and the newborns, could reduce their occurrence and specially those due to abortions.

Purpose: to identify and quantify the underreporting of maternal mortality, from death certificates (DC) in Campinas, São Paulo, from 1992 to 1994. Methods: a total of 216 DC whose causes of death were maternal (declared and/or presumed) were selected among the 1032 DC of 10 to 49-year-old women. A complementary investigation was performed on hospital records, at the death verifying units, and in households. Results: eight additional maternal deaths were identified among the 204 DC with presumed maternal death. This corresponded to an underreporting rate of 40% or to a correction factor of 1.67 for the official MMR. The first cause of underreporting was abortion (71.5% or 05/07) and indirect maternal deaths represented the second cause (66.6% or 02/03). Conclusions: the death certificate cannot be considered the only source to identify maternal death. Complementary investigation of the presumable causes of maternal death should be performed. Legislation, social and religious factors might influence the underreporting of abortion as the cause of maternal death.

Beta thalassemia major is a rare hereditary blood disease in which impaired synthesis
of beta globin chains causes severe anemia. Medical treatment consists of chronic
blood transfusions and iron chelation. We describe two cases of adolescents with beta
thalassemia major with unplanned pregnancies and late onset of prenatal care. One had
worsening of anemia with increased transfusional requirement, fetal growth
restriction, and placental senescence. The other was also diagnosed with
hypothyroidism and low maternal weight, and was admitted twice during pregnancy due
to dengue shock syndrome and influenza H1N1-associated respiratory infection. She
also developed fetal growth restriction and underwent vaginal delivery at term
complicated by uterine hypotonia. Both patients required blood transfusions after
birth and chose medroxyprogesterone as a contraceptive method afterwards. This report
highlights the importance of medical advice on contraceptive methods for these women
and the role of a specialized prenatal follow-up in association with a
hematologist.

PURPOSE: to study cervical colonization in women with preterm labor or premature rupture of membranes. METHODS: two hundred and twelve pregnant women with preterm labor or premature rupture of membranes were studied. Two cervical samples from each woman were collected and bacterioscopy and culture were performed. Association of cervical microorganisms and urinary tract infection, chorioamnionitis, fetal stress, antibiotic use, prematurity, neonatal infection, and neonatal death were evaluated. RESULTS: the prevalence of endocervical colonization was 14.2% (CI95%=9.5-18.9%), with similar results in preterm labor or premature rupture of membranes. Group B streptococcus was the most prevalent organism (9.4%). Other organisms isolated were Candida sp, Streptococcus sp, Streptococcus pneumoniae, Escherichia coli and Enterococcus sp. The most common findings of bacterioscopy were a reduced number of lactobacilli and a great number of leukocytes. Endocervical colonization was associated with a higher occurrence of urinary tract infection (23.8 versus 5.4%; p<0.01), early-onset neonatal infection (25.0 versus 7.3%; p<0.01) and neonatal mortality (two cases in colonized women; p<0.02) when compared with a negative culture of endocervical mucus. CONCLUSIONS: this study showed high prevalence of endocervical colonization despite the use of a nonselective culture media. The main microorganism isolated was group B streptococcus, but other organisms were present in one third of the studied population. More studies are needed to evaluate the influence of endocervical colonization on obstetrical outcome and on neonatal infection and mortality.
