, To evaluate the impact of systematic laparoscopic skills and suture training (SLSST) on the total laparoscopic hysterectomy intra- and postoperative outcomes in a Brazilian teaching hospital.
A cross-sectional observational study in which 244 charts of total laparoscopic hysterectomy (TLH) patients operated from 2008 to 2014 were reviewed. Patient-specific (age, parity, previous cesarean sections, abdominal surgeries and endometriosis) and surgery-related variables (hospital stay, operative time, uterine volume and operative complications) were analyzed in three different time-frame groups: 2008-09 (I-1) - TLHs performed by senior attending physicians; 2010-11 (I-2) - TLHs performed by residents before the implementation of the SLSST program; and 2012-14 (I-3) - TLHs performed by residents after the implementation of the SLSST program.
A total of 244 TLH patients (mean age: 45.93 years) were included: 24 (I-1), 55 (I-2), and 165 (I-3). The main indication for TLH was uterine myoma (66.4%). Group I-3 presented a decrease in surgical time compared to group I-2 (p=0.010). Hospital stay longer than 2 days decreased in group I-3 compared to group I-2 (p=0.010). Although we observed decreased uterine volume (154.2 cm3) in group I-2 compared to group I-1 (217.8 cm3) (p=0.030), logistic regression did not find any association between uterine volume and surgical time (p=0.103).
The total operative time for laparoscopic hysterectomy was significantly shorter in the group of patients (I-3) operated after the systematic laparoscopic skills and suture training was introduced in our hospital.

To determine the prevalence of episiotomy and the factors associated with the knowledge, attitude and practice (KAP) of Brazilian obstetricians in relation to this procedure.
A KAP survey was conducted with obstetricians working in Brazil. An electronic form containing structured questions previously evaluated using the Delphi method was created in Google Docs and sent by e-mail. A multivariate logistic regression was performed to determine the principal factors associated with adequate KAP. For each dependent variable (knowledge, attitude and practice) coded as adequate (1 = yes; 0 = no), a multiple logistic regression model was developed. Binary codes (1 = yes and 0 = no) were assigned to every independent or predictor variables. Prevalence ratios (PRs) and their respective 95% confidence intervals (95%CIs) were calculated as measures of relative risk, at a significance level of 5%.
Out of the 13 thousand physicians contacted, 1,163 replied, and 50 respondents were excluded. The mean episiotomy rate reported was of 42%. Knowledge was determined as adequate in 44.5% of the cases, attitude, in 10.9%, and practice, in 26.8% of the cases.
Most respondents had inadequate knowledge, attitudes and practices regarding episiotomy. Although some factors such as age, teaching, working in the public sector and attending congresses improved knowledge, attitude and practice, we must recognize that episiotomy rates remain well above what would be considered ideal. Adequate knowledge is more prevalent than adequate attitude or practice, indicating that improving knowledge is crucial but insufficient to change the outlook of episiotomies in Brazil.

, The present study aims to compare the maternal and fetal outcomes of parturients with and without a gestational diabetes diagnosis.
A case-control study including parturients with (cases) and without (control) a gestational diabetes diagnosis, who delivered at a teaching hospital in Southern Brazil, between May and August 2018. Primary and secondary data were used. Bivariate analysis and a backward conditionalmultivariate logistic regression were used to make comparisons between cases and controls, which were expressed by odds ratio (OR), with a 95% confidence interval (95%CI) and a statistical significance level of 5%.
The cases (n=47) weremore likely to be 35 years old or older compared with the controls (n=93) (p<0.001). The cases had 2.56 times greater chance of being overweight (p=0.014), and a 2.57 times greater chance of having a positive family history of diabetes mellitus (p=0.01). There was no significant difference regarding weight gain, presence of a previous history of gestational diabetes, height, or delivery route. The mean weight at birth was significantly higher in the infants of mothers diagnosed with diabetes (p=0.01). There was a 4.7 times greater chance of macrosomia (p<0.001) and a 5.4 times greater chance of neonatal hypoglycemia (p=0.01) in the infants of mothers with gestational diabetes.
Therefore, maternal age, family history of type 2 diabetes, obesity and pregestational overweightness are important associated factors for a higher chance of developing gestational diabetes.

, To evaluate the outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation (CPAM).
We retrospectively evaluated cases of prenatally-diagnosed CPAM between 2004 and 2018. Ultrasonographic features such as visualization of a fetal lung mass and heterogeneous pulmonary parenchyma were used for CPAM diagnosis. Prenatal and postnatal findings were compared in terms of accuracy regarding the CPAM diagnosis.
The sample consisted of 27 cases. There were four cases in which the patients opted for the termination of pregnancy due to the severity of the lesion. A total of 23 neonates were delivered, and CPAM was confirmed in 15 cases. Themedian gestational age at delivery was 37 weeks (28-40 weeks) and the mean birth weight was 2,776 g. There were two neonatal deaths, one due to pneumothorax, and the other due to hypoplastic left heart syndrome (HLHS). A total of five patients with respiratory problems were operated in the postpartum period. There were eight misdiagnosis: bronchopulmonary sequestration (five cases), congenital lobar emphysema (two cases), and congenital diaphragm hernia (one case).
A precise postnatal diagnosis is very important to organize the proper management of the pregnancies with fetuses with CPAM. The positive predictive value of the prenatal diagnosis of CPAM via ultrasonography is of 70.3%. The differential diagnosis of CPAM may be prolonged to the postpartum period in some cases.

, The incidence of obesity, which is a chronic condition, has increased in recent years. The association between obesity and female sexual dysfunction remains unclear, particularly in postmenopausal women. In the present study, we evaluated whether obesity is a risk factor for sexual dysfunction in postmenopausal women.
This is a cross-sectional study that analyzed data from interviews of postmenopausal women at the Climacteric Outpatient Clinic from 2015 to 2018. After applying the inclusion and exclusion criteria, 221 women aged between 40 and 65 years old were selected and invited to participate in the study. Obesity was diagnosed according to body mass index (BMI). The participants were grouped into the following BMI categories: group 1, 18.5-24.9 kg/m2 (normal); group 2, 25.0- 29.9 kg/m2 (overweight); and group 3, ≥30.0 kg/m2 (obese). Sexual function was assessed using the Female Sexual Function Index (FSFI) questionnaire. Cutoff points of ≥23 and ≥26.5 were adopted to define a diagnosis of female sexual dysfunction (FSD) based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision by the American Psychiatric Association (DSM-IV-TR).
The desire and arousal scores were statistically higher in the normal BMI group than in the obese group (p=0.028 and p=0.043, respectively). The satisfaction scores were statistically higher in the normal BMI group than in the overweight and obese groups (p<0.05). The total FSFI score statistically differed among the BMI categories (p=0.027).
In the present study, obese and overweight postmenopausal women had higher total scores than women with normal BMI. Our results show that obese and overweight postmenopausal women had a higher index of dysfunction in desire and arousal and lower sexual satisfaction than normal-weight women.

, To evaluate whether the use of intraoperative ultrasound leads to more conservative surgeries for benign ovarian tumors.
Women who underwent surgery between 2007 and 2017 for benign ovarian tumors were retrospectively analyzed. The women were classified into two groups: those who underwent intraoperative ultrasound (group A) and those who did not (group B). In group A, minimally-invasive surgery was performed for most patients (a specific laparoscopic ultrasound probe was used), and four patients were submitted to laparotomy (a linear ultrasound probe was used). The primary endpoint was ovarian sparing surgery (oophoroplasty).
Among the 82 cases identified, only 36 met the inclusion criteria for the present study. Out of these cases, 25 underwent intraoperative ultrasound, and 11 did not. There were no significant differences in arterial hypertension, diabetes, smoking history, and body mass index for the two groups (p=0.450). Tumor diameter was also similar for both groups, ranging from 1 cm to 11 cm in group A and from 1.3 cm to 10 cm in group B (p=0.594). Tumor histology confirmed mature teratomas for all of the cases in group B and for 68.0% of the cases in group A. When the intraoperative ultrasound was performed, a more conservative surgery was performed (p<0.001).
The use of intraoperative ultrasound resulted in more conservative surgeries for the resection of benign ovarian tumors at our center.

The aim of this study was to investigate the knowledge concerning gestational weight gain (GWG), nutrition, and physical exercise (PE) in pregnant women, and how to put them into practice.
A cross-sectional study with 61 pregnant women above 26 weeks of gestation, at the Woman’s Hospital, CAISM, University of Campinas. Questionnaires regarding the knowledge of healthy habits (HH) during pregnancy, sociodemographic data, and previous obstetric outcomes were applied. An educational guide with advice on HH during pregnancy and in the postpartum period was offered.
The average age of women was 28.7 ± 6.23 years, with 85% of them being married; 32% nulliparous; the average body mass index (BMI) before pregnancy was 25.4 ± 9.8 kg/m2, and themean number of years of schoolingwas 11.2 ± 3.8. Only 61%of the subjects had received any previous information about GWG during their antenatal care and were aware as to howmany pounds they should gain during pregnancy. Among the 61 women, 85% understood that they did not need to “eat for 2” and 99% knew that PE had benefits for their body and was safe for their baby. Half of the women practiced PE prior to pregnancy; however, only 31% continued the practice of PE during the pregnancy.
Despite understanding the need for HH during pregnancy, women still need encouragement to practice PE during pregnancy, as well as more information about GWG.

, Labor induction does not always result in vaginal delivery, and can expose both the mother and the fetus to the risks inherent to the induction procedure or a possible cesarean section. Transvaginal sonography (TVS) of the cervix is a useful tool to predict prematurity; in the present study, this tool was used to evaluate postterm induction.
We evaluated the ultrasound characteristics of the cervix (cervical length, cervical funneling, internal os dilation, the presence or absence of the cervical gland area [CGA], and the morphological changes of the cervix as a result of applying fundal pressure) before the onset of labor induction among women with postterm pregnancy to identify the possible predictors of failed labor induction. The Bishop score (BS) was used for comparison purposes. Three groups were evaluated: successful versus unsuccessful induction; vaginal delivery versus cesarean delivery (excluding cases of acute fetal distress [AFD]); and vaginal delivery versus cesarean delivery (including cases of AFD). A fourth group including only the primiparous women from the three previous groups was also evaluated.
Based on the studied characteristics and combinations of variables, a cervical length ≥ 3.0 cm and a BS ≤ 2 were the best predictors of induction failure.
Although TVS is useful for screening for induction failure, this tool should not be used as an indication for cesarean section.
