    Abstract

    Objective

    To investigate the association between prenatal care (PNC) adequacy indexes and the low birth weigth (LBW) outcome.

    Methods

    A total of 368,093 live term singleton births in the state of Rio de Janeiro (Brazil) from 2015 to 2016 were investigated using data from the Brazilian Live Birth Information System (Sistema de Informações sobre Nascidos Vivos, SINASC, in Portuguese). Seven PNC adequacy indexes were evaluated: four developed by Brazilian authors (Ciari Jr. et al., Coutinho et al., Takeda, and an index developed and used by the Brazilian Ministry of Health - MS) and three by authors from other countries (Kessner et al., the Adequacy of Prenatal Care Utilization index - APNCU, and the Graduated Prenatal Care Utilization Index - GINDEX). Adjusted odds ratios were estimated for the PNC adequacy indexes by means of multivariate logistic regression models using maternal, gestational and newborn characteristics as covariates.

    Results

    When the PNC is classified as “inadequate”, the adjusted odds ratios to the LBWoutcome increase between 42% and 132%, depending on which adequacy index is evaluated. Younger (15 to 17 years old) and older (35 to 45 years old) mothers, those not married, of black or brown ethnicity, with low schooling (who did not finish Elementary School), primiparous, with preterm births, as well as female newborns had increasing odds for LBW. The models presented areas under the receiver operating characteristic (ROC) curve between 80.4% and 81.0%, and sensitivity and specificity that varied, respectively, between 57.7% and 58.6% and 94.3% and 94.5%.

    Conclusion

    Considering all PNC adequacy indexes evaluated, the APNCU had the best discriminatory power and the best ability to predict the LBW outcome.

    Abstract

    Objective

    To evaluate the applicability and usefulness of second-trimester TUCL to predict PTB in a cohort of Portuguese pregnant women.

    Methods

    Retrospective cross-sectional cohort study including all singleton pregnant women who performed their second-trimester ultrasound (between weeks 18 and 22þ6 days) from January 2013 to October 2017 at Centro Hospitalar Universitário São João.

    Results

    Our cohort included 4,481 women. The prevalence of spontaneous PTB was of 4.0%, with 0.7% occurring before the 34th week of gestation. The mean TUCL was of 33.8mm,and percentiles 3, 5 and 10 corresponded toTUCLs of 25.0mm, 27.0mmand 29.0mmrespectively. The multiple logistic regression analysis, including maternal age, previous PTB and cervical surgery showed a significant negative association between TUCL and PTB, with an odds ratio (OR) of 0.92 (95% confidence interval [95%CI]: 0.90-0.95; p<0.001). The use of a TUCL of 20mm is the best cut-off, when compared with the 25-mm cut-off, improving the prediction of risk.

    Conclusion

    The present study showed an inverse association between TUCL and PTB, and that the inclusion of other risk factors like maternal age, previous PTB and cervical surgery can improve the screening algorithm. Furthermore, it emphasizes that the TUCL cut-off that defines short cervix can differ according to the population.

    Abstract

    Objective

    Childbirth is a biological, psychological, and sociological event that can be a positive or negative experience, and, without support, this period may be potentially damaging. Parturition may distort maternal emotions and lead to short- or long-term disorders such as postpartum depression and anxiety. The present research aims to study the effects of dialectic behavioral therapy-based counseling on depression, anxiety symptoms, and postpartum hematocrit level.

    Methods

    The current research is a clinical trial study, and the sample was selected using parturients who were referred to the Health General Center with a diagnosis of postpartum depression and anxiety. The sample size consisted of 116 subjects who agreed to participate in the study. The patients in intervention group underwent group dialectic behavioral counseling (10 sessions/one session per week) and the control group did not receive any type of intervention. The patients were assessed in the first and last sessions as well as 2 months after the end of the sessions, using the Beck depression scale and Spielberg anxiety scale as well as the results of hematocrit tests. Data were analyzed using the IBMSPSS Statistics for Windows, Version 21.0 (IBMCorp., Armonk, NY, USA)

    Results

    The results implied the effectiveness of dialectic behavioral therapy on reduction of the depression score, anxiety symptoms (p-value ≤ 0.0001), and hematocrit level (p-value=0.04). The participants’ depression, anxiety, and hematocrit levels decreased in the experiment group compared to the control group, and this decrease has remained until the 2-month follow-up.

    Conclusion

    It seems that dialectic behavioral counseling reduces the levels of postpartum depression, anxiety, and hematocrits.

    Abstract

    Objective

    Cesarean section (CS) delivery, especially without previous labor, is associated with worse neonatal respiratory outcomes. Some studies comparing neonatal outcomes between term infants exposed and not exposed to antenatal corticosteroids (ACS) before elective CS revealed that ACS appears to decrease the risk of respiratory distress syndrome (RDS), transient tachypnea of the neonate (TTN), admission to the neonatal intensive care unit (NICU), and the length of stay in the NICU.

    Methods

    The present retrospective cohort study aimed to compare neonatal outcomes in infants born trough term elective CS exposed and not exposed to ACS. Outcomes included neonatal morbidity at birth, neonatal respiratory morbidity, and general neonatal morbidity. Maternal demographic characteristics and obstetric data were analyzed as possible confounders.

    Results

    A total of 334 newborns met the inclusion criteria. One third of the population study (n=129; 38.6%) received ACS. The present study found that the likelihood for RDS (odds ratio [OR]=1.250; 95% confidence interval [CI]: 0.454-3.442), transient TTN (OR=1.,623; 95%CI: 0.556-4.739), and NIUC admission (OR=2.155; 95%CI: 0.474-9.788) was higher in the ACS exposed group, although with no statistical significance. When adjusting for gestational age and arterial hypertension, the likelihood for RDS (OR=0,732; 95%CI: 0.240-2.232), TTN (OR=0.959; 95%CI: 0.297--3.091), and NIUC admission (OR=0,852; 95%CI: 0.161-4.520) become lower in the ACS exposed group.

    Conclusion

    Our findings highlight the known association between CS-related respiratory morbidity and gestational age, supporting recent guidelines that advocate postponing elective CSs until 39 weeks of gestational age.

    Abstract

    Objective

    To evaluate whether continuation rates with the 52-mg levonorgestrelreleasing intrauterine system (LNG-IUS) up to 5 years after placement differed between women using the method exclusively for contraception and those using the device for medical reasons alone.

    Methods

    A retrospective cohort study was conducted in a family planning clinic with 5,034 LNG-IUS users: 4,287 using the method exclusively for contraception and 747 for medical reasons alone. The continuation rate at 1 to 5 years of use was calculated by life table analysis.

    Results

    Initially, the continuation rate was significantly higher in the contraception group: 85.8 versus 83.4 and 77.4 versus 76.0 per 100 women-years in the 1st and 2nd years of use, respectively. There were more discontinuations due to bleeding/spotting in the medical reasons group in the first two years. The discontinuation rate according to reason for use was not significantly different from the third to the fifth year of use. No women discontinued due to amenorrhea in either group.

    Conclusion

    The continuation rate was significantly higher in the contraception group in the first two years of use. Amenorrhea was not a reason for discontinuation in either group, suggesting that counselling in this respect was adequate. Nevertheless, counselling could perhaps have been better with regards to the expected long period of bleeding and spotting in the first two years after placement.

    Abstract

    Objective

    To evaluate serum levels of adiponectin in pregnant adolescents between 30 and 36 weeks of gestation.

    Method:

    A prospective cross-sectional study enrolled 67 normal pregnant women between 30 and 36 weeks of gestation and eutrophic (body mass index [BMI]: 18.5-25 kg/m2), of which 36 were adolescents (< 20 years old) and 31 adults (≥ 20 years old). Serum adiponectin levels were determined by enzyme-linked immunosorbent assay (ELISA). The t-student or Mann-Whitney tests were used for intergroup comparison.

    Results

    Pregnant adolescents showed significantly higher serum adiponectin concentrations comparedwith pregnant adults (p=0.04). No differences were observed in adiponectin levels in younger pregnant adolescents (< 16 years old) compared with older pregnant adolescents (≥ 16 years old). Adiponectin values were divided into 3 subgroups:<3,000 ng/mL, between 3,000 and 5,000 ng/mL, and>5,000 ng/mL. Birthweight was significantly higher in women>5,000 ng/mL when compared with<3,000 ng/mL in the adolescent group. No association between pregestational adiponectin levels and BMI, gestational weight gain, and gestational age was observed; however, there was a positive relation with birthweight (p=0.0239).

    Conclusion

    Serum adiponectin values in pregnant adolescents between 30 and 36 weeks of gestation were higher compared with pregnant adults; however, no differences between younger and older pregnant adolescents were observed.

    Abstract

    Objective

    To describe the obstetric outcomes of patients withmultiple sclerosis (MS) and the impact of pregnancy and the postpartum period on the progression of the disease.

    Methods

    A case series study performed between December 2019 and February 2020, reporting pregnancies occurred between 1996 and 2019. The subjects included were women with MS undergoing follow-up at an MS referral center in Northeastern Brazil, and who had at least one pregnancy after the onset of MS symptoms, or who had their first relapse in the first year after delivery.

    Results

    In total, 26 women and 38 pregnancies were analyzed - 32 of them resulted in delivery, and the remaining 6, in miscarriages. There was a significant increase in the prevalence of relapse during the postpartum period when compared with the gestational period. In 16 (42.1%) of the pregnancies, there was exposure to diseasemodifying therapies (DMTs) - 14 (36.8%), to interferon β, and 2 (5.3%), to fingolimod. Higher rates of abortion, prematurity and low birth weight were reported in the group was exposed to DMT when compared with the one who was not.

    Conclusion

    In the sample of the present study, there was a significant increase in the rate of MS relapse during the postpartum period when compared with the gestational period. Additionally, it seems that exposure to DMTs during pregnancy may affect the obstetric outcomes of the patients.

    Abstract

    Objective

    To evaluate the acceptability of postplacental placement of intrauterine devices (PPIUD), reasons for refusal and suggested policies to increase its use.

    Methods

    Cross-sectional study conducted at the Women Hospital of the Universidade de Campinas, Campinas, SP, Brazil. Postplacental placement of intrauterine devices was offered to women admitted in labor who did not present infections, uterinemalformation, twin pregnancy, preterm birth, and were at least 18 years old. In case of refusal, the parturient was asked to give their reasons and the answers were classified as misinformation about contraception or other reasons. The following were considered misinformation: fear of pain, bleeding, contraception failure and future infertility. Bivariate analysis was performed.

    Results

    Amongst 241 invited women, the refusal rate was of 41.9%. Misinformation corresponded to 50.5% of all refusals, and the reasons were: fear of pain (39.9%); fear of contraception failure (4.9%); fear of bleeding (3.9%); fear of future infertility (1.9%); other reasons for refusal were 49.5%. Parturients aged between 18 and 27 years old refused the PPIUD more frequently due to misinformation (67.4%), and older parturients (between 28 and 43 years old) refused frequently due to other reasons (63.6%) (p=0.002). Themean age of those who declined the PPIUD due to misinformation was 27.3 ± 6.4 years old, while those who declined for other reasons had a mean age of 29.9 ± 5.9 years old (p=0.017).

    Conclusion

    The refusal of the PPIUD was high, especially amongst young women and due to misinformation. It is necessary to develop educative measures during antenatal care to counsel women about contraception, reproductive health and consequences of unintended pregnancy.
