, To evaluate and compare the prevalence of structural congenital anomalies (CAs) according to maternal body mass index (BMI).
The present cross-sectional study involved pregnant women with fetuses diagnosed with structural CAs through morphological ultrasonography between November 2014 and January 2016. The nutritional status of the pregnant women was classified according to the gross value of the body mass index. The pregnant women were categorized into four groups: low weight, adequate weight, overweight, and obesity. Statistical analysis was performed using Stata/SE version 12.0 (Stata Corporation, College Station, TX), with values of p ≤ 0.05 considered statistically significant.
A total of 223 pregnant women had fetuses diagnosed with CAs. The prevalence of structural CAs in pregnant women with lowweight was of 20.18%, of 43.50% in pregnant women with adequate weight, of 22.87% in pregnant women with overweight, and of 13.45% in pregnant women with obesity. The prevalence of central nervous system (CNS) anomalies and of genitourinary systemanomalieswas high for the four groups of pregnant women. A positive association was observed between multiple anomalies in pregnant women with adequate weight (prevalence ratio [PR] = 1.65; p ≤ 0.004) and between anomalies of the lymphatic system in obese pregnant women (PR = 4.04, p ≤ 0.000).
The prevalence of CNS and genitourinary systemanomalies was high in all of the BMI categories. Obese pregnancies were associated with lymphatic system anomalies. Therefore, screening and identification of the risk factors for CAs are important, regardless of the maternal BMI. Our findings reinforce the importance of discussing with pregnant women maternal nutrition and its effect on fetal development and on neonatal outcome.

, To evaluate the level of information possessed by pregnant adolescents regarding the human papillomavirus (HPV).
Descriptive study developed in the adolescent prenatal outpatient clinic of a tertiary hospital fromthe state of São Paulo, Brazil. Data were collected between June and December 2017 following approval from the ethics and research committee (CAAE: 1.887.892/2017). Pregnant adolescents, ≤18 years old, who attended the abovementioned outpatient section, composed the sample. Those diagnosed with a psychiatric disorder and those with hearing or cognitive disabilities were excluded. After acceptance to participate in the present study, the pregnant adolescents signed an Informed Consent Form. Regarding the statistical analysis, the chi-squared test and the Fisher exact test were used.
Regarding the knowledge about HPV, 123 (80.92%) of the participants had already heard about the subject; for 77 (50.66%), their schools had been the source of the information; 101 (66.45%) did not know how they could be infected by the virus. Age variation did not influence their knowledge on how to prevent themselves from HPV (p = 0.2562). The variable vaccine is associated with HPV prevention (p < 0.0001).
The pregnant adolescents composing the sample have shown to have knowledge about HPV. However, they do not prevent themselves from it appropriately, given that little more than half of the sample was vaccinated, had not reported an understanding that the use of preservatives and vaccination are effective means of prevention, and did not correlate HPV with uterine cervical cancer.

, Gestational diabetes mellitus (GDM) is associated with a higher risk of perinatal morbidity and mortality, and its main complication is the occurrence of large for gestational age (LGA) newborns. The present study aims to characterize pregnant women with GDM and to identify factors associated with the occurrence of LGA newborns in this population.
A cross-sectional study was performed based on medical records of women whose prenatal care and delivery were performed at the Maternal and Child Unit of the HospitalUniversitário of theUniversidade Federal doMaranhão, state of Maranhão, Brazil.A total of 116 pregnant women diagnosed with GDMwere included according to the criteria of the International Association of Diabetes and Pregnancy Study Groups (IADPSG).
The variables associated with LGA newborns after multivariate analysis were: obesity prior to pregnancy (OR = 11.6; 95% CI: 1.40-95.9), previous macrosomia (OR = 34.7; 95% CI: 4.08-295.3), high blood glucose levels in the 3rd trimester (OR = 2,67; 95% CI: 1.01-7.12) and combined change in the oral glucose tolerance test (OGTT) (fasting + postdextrose) (OR = 3.53;95%CI:1.25-14.2) = 1.17-10.6).Otherwise, insufficientweight gain during pregnancy reduced the risk for LGA newborns (OR = 0.04; 95% CI: 0.01-0.32).
Obesity prior to pregnancy, previous macrosomia, high blood glucose levels in the 3rd trimester, and combined change in the OGTT were independent predictive factors for LGA newborns in pregnant women with GDM.

, To compare laparoscopy with laparotomy for surgical staging of endometrial cancer.
A cohort of women with preoperative diagnosis of endometrial cancer who underwent surgical staging was retrospectively evaluated. The main study end points were: morbidity and mortality, hospital length of stay, perioperative adverse events and recurrence rate. Data analysis was performed with the software SPSS v25 (IBM Corp., Armonk, NY, USA), categorical variables using a Chi-square and Fisher test, and continuous variables using the Student t-test.
Atotal of 162 patientswere analyzed. 138 patientsmet the inclusion criteria, 41of whom underwent staging by laparoscopy and 97 by laparotomy. Conversions from laparoscopy to laparotomy happened in 2 patients (4.9%) and were secondary to technical difficulties and poor exposure. Laparoscopy had fewer postoperative adverse events when compared with laparotomy (7.3% vs 23.7%, respectively; p = 0.005), but similar rates of intraoperative complications, despite having a significantly longer operative time (median, 175 vs 130 minutes, respectively; p < 0.001). Hospital stay was significantly lower in laparoscopy versus laparotomy patients (median, 3 vs 7 days, respectively; p < 0.001). No difference in recurrence or mortality rates were observed.
Laparoscopic surgical staging for endometrial cancer is feasible and safe. Patients have lower postoperative complication rates and shorter hospital stays when compared with the approach by laparotomy.

To evaluate the quality of life among university students with premenstrual syndrome (PMS).
The cross-sectional study was conducted at the Faculdade Pernambucana de Saúde, in Recife, Brazil, between August 2016 and July 2017. Sociodemographic, gynecological, and lifestyle variables, and PMS occurrence, were investigated among 642 students. The short form of the World Health Organization Quality of Life (WHOQOL Bref) questionnaire was used to evaluate four domains of the quality of life of the students: physical, mental, social relationships, and environmental. The American College of Obstetricians and Gynecologists’ criteria were used to define PMS.
Of the 642 students, 49.9% had PMS, 23.3% had mild PMS and 26.6% had premenstrual dysphoric disorder (PMDD). Most of the students were between 18 and 24 years old, had regular menstrual cycles, and practiced physical activity. Regarding the physical and mental domains of the WHOQOL-Bref questionnaire, a statisticallysignificant difference was observed between the students who did not have and those who had mild or PMDD (p < 0.001). A difference was also found between the students who did not have PMS and those who had mild PMS in the social relationships (p = 0.001) and environmental domains (p = 0.009).
Mild PMS and PMDD are prevalent among university students on healthrelated courses, and the syndrome can affect the students’ self-assessment of all the domains of quality of life.

, Pre-eclampsia is a multifactorial and multisystemic disease specific to gestation. It is classically diagnosed by the presence of hypertension associated with proteinuria manifested in a previously normotensive pregnant woman after the 20th week of gestation. Pre-eclampsia is also considered in the absence of proteinuria if there is target organ damage. The present review takes a general approach focused on aspects of practical interest in the clinical and obstetric care of these women. Thus, it explores the still unknown etiology, current aspects of pathophysiology and of the diagnosis, the approach to disease prediction, its adverse outcomes and prevention. Management is based on general principles, on nonpharmacological and on pharmacological clinical treatment of severe or nonsevere situations with emphasis on the hypertensive crisis and eclampsia. Obstetric management is based on preeclampsia without or with signs of clinical and/or laboratory deterioration, stratification of gestational age

, To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW).
The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/ use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis.
Maternal alcohol consumption was associated with LBWamong retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10-1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98-1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68-1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW.No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year.
We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.

, Vasa previa (VP) is a dangerous obstetric condition associated with perinatal mortality and morbidity. In vitro fertilization (IVF) is a risk factor for VP due to the high incidence of abnormal placentation. The diagnosis should be made prenatally, because fetal mortality can be extremely high. We report two cases to demonstrate the accuracy of transvaginal ultrasound in the prenatal diagnosis of VP. A 40-year-old primiparous Caucasian woman with IVF pregnancy was diagnosed with VP at 29 weeks of gestation and was hospitalized for observation at 31 weeks of gestation. She delivered a male newborn weighing 2,380 g, with an Apgar score of 10 at 5 minutes, by elective cesarean section at 34 weeks + 4 days of gestation, without complications. A 36-yearold primiparous Caucasian woman with IVF pregnancy was diagnosed with placenta previa, bilobed placenta increta and VP. The cord insertion was velamentous. She was hospitalized for observation at 26 weeks of gestation. She delivered a female newborn weighing 2,140 g, with an Apgar score of 9 at 5 minutes, by emergency cesarean section at 33 weeks + 4 days of gestation due to vaginal bleeding. The prenatal diagnosis of VP was associated with a favorable outcome in the two cases, supporting previous observations that IVF is a risk factor for VP and that all IVF pregnancies should be screened by transvaginal ultrasound.
