, To describe the immunological and hematological reference intervals of low-risk pregnant women.
A cross-sectional retrospective database analysis of a basic and translational study analyzing the hematological evaluation blood counts and immunophenotyping of TCD3 + , TCD4 + , TCD8 + , B, and natural killer (NK) cells of the peripheral blood in 79 low-risk pregnant women and of 30 control women from the state of Pernambuco, Brazil, was performed.
No significant differences were detected between the hematological profiles of the 2nd and 3rd trimesters. Nevertheless, the median level of B cells decreased significantly in the 2nd (174 x 103 μL; p < 0.002) and 3rd trimesters (160 x 103 μL; p < 0.001), compared with the control group (296 x 103 μL). Similarly, the median level of NK cells was lower in the 2nd (134 x 103 μL; p < 0.0004) and 3rd trimesters (100 x 103 μL, p < 0.0004), compared with the control group (183 x 103 μL). In contrast, relative TCD4+ and TCD8+ levels increased in the 2nd and 3rd trimesters compared with the controls (TCD4 + : 2nd trimester = 59%; p < 0.001; 3rd trimester = 57%; p < 0.01; control = 50%; and TCD8 + : 2nd trimester = 31%; p < 0.001; 3rd trimester = 36%; p < 0.01; control = 24%).
Low-risk pregnant women have ~ 40% less B and NK cells in the peripheral blood, compared with non-pregnant women. These parameters may improve health assistance for mothers and contribute to define reference values for normal pregnancies.

To describe the maternal and fetal outcomes with the use of the Foley catheter for induction of labor in high-risk pregnant women with previous caesarean section.
An interventive and descriptive study was conducted from November 2013 to June 2014. A total of 39 pregnant women at term, with a live fetus, cephalic presentation, estimated fetal weight <4,000 g, with previous cesarean section, medical indications for induction of labor, Bishop score ≤6 and amniotic fluid index >5 cm were included. A number 16F Foley catheter was introduced for a maximum of 24 hours, and was considered to be satisfactory when the patient began labor within 24 hours.
Labor was successfully induced in 79.5% of pregnant women. Nine women achieved vaginal delivery (23.1%), with a frequency of 18% of vaginal births occurring within 24 hours. The main indications for the induction of labor were hypertensive disorders (75%). The mean interval between the placement of the Foley catheter and the beginning of labor and delivery were 8.7±7.1 and 14.7±9.8 hours, respectively. Meconium-stained amniotic fluid was observed in two patients; and an Apgar score <7 in the first minute was detected in 5 newborns (12.8%).
The Foley catheter is an alternative for the induction of labor in women with previous caesarean section, despite the low vaginal delivery rate.
