Gestational diabetes mellitus (GDM)is an entity with evolving conceptual nuances that deserve full consideration. Gestational diabetes leads to complications and adverse effects on the mother's and infants' health during and after pregnancy. Women also have a higher prevalence of urinary incontinence (UI) related to the hyperglycemic status during pregnancy. However, the exact pathophysiological mechanism is still uncertain. We conducted a narrative review discussing the impact of GDM on the women's pelvic floor and performed image assessment using three-dimensional ultrasonography to evaluate and predict future UI.

Purpose: to evaluate maternal hemodynamic and cardiac structural changes during the three trimesters of pregnancy and to relate them to the weight/gestational age of the newborn. Methods: twenty-two healthy pregnant women were submitted to echocardiography for the study of cardiac output, mean arterial pressure, left atrium diameter, and peripheral resistance during three periods of pregnancy, i.e., before the 12th week and at the 26thand 36th weeks of pregnancy. Seventeen pregnant women gave birth to infants with adequate weight for gestational age, four gave birth to small for gestational age newborns and one gave birth to a large for gestational age infant. Results: among mothers of low weight newborns, cardiac output and left atrium diameter remained constant, mean arterial pressure showed a tendency to increase and peripheral resistance was significantly increased (28%), during the gestation. Among the mothers of adequate weight newborns there was an increase in cardiac output of 19% in the second trimester and 8% in the third. The left atrial diameter increased approximately 9% during the gestation, with maintenance of mean arterial pressure and a tendency to a decrease in peripheral resistance. Conclusion: the present results support an association between hemodynamic adaptation and weight newborn.

Purpose: to study trial of labor (TOL) for vaginal birth after one previous cesarean section. Methods: this is a retrospective cohort study that included 438 pregnant women with one previous cesarean section and their 450 newborns. They were divided into two groups - with and without TOL. The minimum sample size was 121 pregnant mothers per group. TOL was considered as an independent variable and vaginal birth and maternal and perinatal complication frequency as dependent variables. Both univariate and multivariate analyses were performed. The comparison of observed frequencies (%) was analyzed by the chi-squared test (chi²) with 5% significance, and linear regression from the odds ratio (OR) and confidence interval of 95% (CI95%). Results: TOL was used in 59.2% of vaginal deliveries. It was less used in women over 40 years (2.7% vs 6.7%) and in those with clinical or obstetrical diseases such as arterial hypertension (7.0%) and bleeding in the third trimester (0.3%). There was a higher risk for puerperal complications with cesarean deliveries (OR = 3.53, CI 95% = 1.57-7.93), independent of TOL. Perinatal mortality was dependent on neonatal weight and fetal malformations, not on TOL. Newborns from mothers not submitted to TOL were at a higher risk for developing breathing complications (OR = 1.92 CI 95% = 1.20-3.07). Conclusions: The results confirm that trial of labor after a previous cesarean section is a safe method - assisting vaginal delivery in 59.2% of births and not interfering with maternal and perinatal mortality. It is a treatment that should be stimulated.

Purpose: to develop an experimental model in rats to study the interaction between hypertension and pregnancy. Methods: the present experiment was divided into 5 periods: adaptation (2 weeks), surgical procedures (1 week), hypertension development (6 weeks), mating and blood pressure stabilization (6 weeks), and gestational period (3 weeks). A total of 82 animals in reproductive age, weighing from 180 to 240 g, were used. They were randomly assigned to the 4 different groups (control, handled, nephrectomy and hypertension) and renal hypertension was produced by a controlled constriction of the main left renal artery, according to the technique described by Goldblatt, and contralateral nephrectomy (Goldblatt I - one kidney, one clip hypertension). They were studied at 15 precise moments. Afterwards, periodic blood pressure determinations were made by the tail plethysmographic method. Results: pregnancy caused a fall in blood pressure levels in the rat. Conclusion: the experimental model was adequate for the purposes of the study, since it proved to be efficient in producing hypertension.

PURPOSE: to compare two methodologies for the calculation of placental volume in normal term pregnancies: one according to the Archimedes principle and the other to the cylinder volume, to estimate the absolute placental densities. Also, to define the methodology which relates to the weight and to the newborn classification. METHOD: fifty placentas from normal term pregnancies were tested by the two methodologies to estimate the placental volume and absolute density: a) Archimedes principle, and b) the cylinder volume with two possible different heights. The absolute placental densities were calculated, respectively, by the quotient between the placenta weight, properly standardized, and the different estimated volumes. RESULTS: most of the pregnant women had more than one gestation, average age of 25.4 years, mean placental volume between 547.8 and 610 cm³ and mean density between 0.94 and 1.14 g/cm³, depending on the used methodology. CONCLUSIONS: the Archimedes principle was the most appropriate methodology to estimate the term placental volume, best correlating with the newborn weight, the placental index and the classification of newborn weight in relation to gestational age.
