    Abstract

    Objective

    To analyze the profiles of women who accepted and who refused the insertion of the copper intrauterine device (IUD) postpartum and to learn the motivations related to the refusal of the method.

    Methods

    Cross-sectional study with 299 pregnant women. The women were informed about the possibility of inserting a copper IUD postpartum and were questioned about their interest in adopting or not this contraceptive. All participants answered a questionnaire with information relevant to the proposals of the present study. The sample size was limited to the number of devices available for the present study.

    Results

    A total of 560 women were invited to join the present study and 299 accepted. Out of the 299 women included in the present study, 175 accepted the copper IUD and 124 refused. As the number of pregnancies increased, the IUD acceptance rate raised (p=0.002), especially between the groups with 1 and with ≥ 4 pregnancies (p=0.013). Regarding the desire to havemore children, the women who planned to have more children were more likely to refuse the method than the ones who did not (p<0,001).

    Conclusion

    Women with multiple pregnancies and desire to not have more children were more likely to accept the copper IUD. The profile of those who refused was first pregnancy and desire to have more children. Among the three most frequent reasons reported for copper IUD rejection, two responses stood out: no specific justification and desire to have more children.

    Abstract

    Objective

    Premature ovarian insufficiency (POI) contributes significantly to female infertility. Cyclophosphamide (CYC has adverse effects on folliculogenesis. Platelet-rich plasma (PRP) is an autologous product rich in many growth factors. We evaluated the protective effect of PRP on in vitro fertilization in female rats with CYC-induced ovarian damage.

    Methods

    Twenty-eight adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose intraperitoneal [IP] injection); group 2 (CYC), 75mg/kg, single-dose IP injection and sodium chloride 0.9% (1mL/kg, single-dose IP injection); group 3 CYC plus PRP, CYC (75 mg/kg, single-dose and PRP (200 μl, single-dose) IP injection); and group 4 (PRP, 200 μl, singledose IP injection).

    Results

    In the comparisons in terms of M1 and M2 oocytes, it was observed that the CYC group presented a significantly lower amount than the control, CYC/PRP, and PRP groups. (for M1, p=0.000, p=0.029, p=0.025; for M2, p=0.009, p=0.004, p=0.000, respectively). The number of fertilized oocytes and two-celled good quality embryos was found to be statistically significant between the CYC and control groups, CYC+PRP and PRP groups (p=0.009, p=0.001, p=0.000 for oocytes, respectively. For embryos; p=0.016, p=0.002, p=0.000).

    Conclusion

    Platelet-rich plasma can protect the ovarian function against damage caused by CYC, and, in addition, it improves oocyte count and the development of embryos as a result of oocyte stimulation during the IVF procedure.

    Abstract

    Objective

    To evaluate genital hygiene among women with and without bacterial vaginosis (BV) and/or vulvovaginal candidiasis (VVC).

    Methods

    A cross-sectional study of reproductive-aged women who underwent gynecological and laboratory tests and fulfilled a genital hygiene questionnaire.

    Results

    This study evaluated 166 healthy controls and 141 women diagnosed with either BV (n=72), VVC (n=61), or both (n=8). The use of intimate soap and moist wipes after urination was more frequent among healthy women (p=0.042 and 0.032, respectively). Compared to controls, bactericidal soap was more used by women with BV (p=0.05).

    Conclusion

    Some hygiene habits were associated to BV and/or VVC. Clinical trials should address this important issue in women’s health.

    Abstract

    Objective

    To determine the accuracy of colposcopy findings in diagnosing cervical intraepithelial neoplasia (CIN) in women with an atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) pap smear result and analyze whether the prevalence of HSIL and cancer correlates with sociodemographic risk factors and specific colposcopic findings.

    Methods

    Colposcopic findings and sociodemographic risk factors were analyzed as possible predictors of a CIN 2 or worse diagnosis in women with an ASC-H pap smear result.

    Results

    Accuracy of the colposcopic impression was 92%, sensitivity was 91.6%, and specificity was 93.1%, with a positive predictive value of 96.4% and negative predictive value of 84.3%. Diagnosis of CIN 2 or worse was more frequent in patients with a previous history of cervical dysplasia and pre-menopausal patients. Identification of major colposcopic findings, dense acetowhite epithelium, coarse mosaicism, and punctuation correlated significantly with CIN 2 or worse.

    Conclusion

    Colposcopy performed by an experienced examiner can accurately differentiate patients with CIN 1 or less from patients with CIN 2 or worse. Diagnosis of CIN 2 or worse was more frequent in patients with a previous history of cervical dysplasia and pre-menopausal patients. The degree of acetowhite changes was the best colposcopic feature to predict CIN2 or worse.

    Abstract

    Objective

    To assess the levels of physical activity and exercise practice, and examine the associated maternal characteristics; as well as the anxiety levels of high-risk pregnant women.

    Methods

    A cross-sectional study conducted with pregnant women at a High-risk Prenatal Clinic (HRPC) in a tertiary maternity. Pregnant women of 18 to 40-years-old, with a single fetus, and with gestational age up to 38 weeks were included. The level of physical activity and exercise practice of the study’s participants were investigated using the Pregnancy Physical Activity Questionnaire (PPAQ). Maternal sociodemographic, anthropometric, and medical data were investigated using a specific form. For anxiety levels, the short version of the State-Trait Anxiety Inventory (STAI) was applied. We used the Student t-test, chi-square test, odds ratio (OR) with 95% confidence interval (95% CI) and multiple logistic regression. The significance level was 5%.

    Results

    Among the 109 pregnant women included, 82 (75.2%) were classified as sedentary/little active. The higher energy expenditure were for domestic activities (133.81±81.84 METs), followed by work-related activities (40.77±84.71 METs). Only 19.3% women exercised during pregnancy (4.76±12.47 METs), with slow walking being the most reported exercise. A higher level of education was the most important factor associated with women being moderately or vigorously active (OR=29.8; 95% CI 4.9-117.8). Nulliparity (OR=3.1; 95% CI 1.0-9.1), low levels of anxiety (OR=3.6; 95% CI 1.2-10.7), and unemployment (OR=4.8; 95% CI 1.1-19.6) were associated with the practice of exercise during pregnancy.

    Conclusion

    Most women with high-risk pregnancies exhibited a sedentary pattern, with low prevalence of physical exercise practice. Recognizing factors that hinder the adoption of a more physically active lifestyle is essential for an individualized guidance regarding exercise during pregnancy.

    Abstract

    Objective

    To evaluate the role of cervical cytology (Pap smear) in the diagnosis of cervical intraepithelial neoplasia 2 or greater (CIN2+), presented exclusively in the endocervical canal, the clinical-epidemiological characteristics of this lesion, the necessary length of canal to be removed to treat, and the rate of invasive lesion hidden in the endocervical canal.

    Methods

    Cross-sectional study, by database analysis, of patients with abnormal cytology (high-grade squamous intraepithelial lesion [HSIL]), without visible colposcopy lesion, submitted to loop electrosurgical procedure (LEEP) to evaluate the association of cytology results with the histological product of the conization, to identify the epidemiological characteristics of endocervical lesion and clinical evolution, using a pvalue< 0.05 and 95% CI.

    Results

    In 444 cases, the Pap smear sensitivity for CIN2+ diagnosis was 75% (95% CI: 69.8-79.7), specificity was 40% (95% CI: 30.2-49.5), and the prevalence rate of histological lesion was 73% (95% CI: 70.1-78.7). There was a higher prevalence of CIN2+ in women over 42 years old and invasive cancer in those over 56 years old (p<0.001), and it was necessary to remove 2.6 cm in length of the canal to reduce the chance of recurrence (p<0.006). The rate of invasive cancer was 2.7%.

    Conclusion

    Cytology was related to a high prevalence to histological lesion (73%) in the diagnosis of CIN2+ in the endocervical disease; older patients presented a higher relationship with histological lesions in the canal disease, and it was necessary to remove an average of 2.6 cm in length of the endocervical canal to avoid the persistence and progression of CIN. The rate of occult neoplasia in the endocervical canal was 2.7%.

    Abstract

    Objective

    To detect depression during pregnancy and in the immediate postpartum period using the Edinburgh postpartum depression scale (EPDS).

    Methods

    Cross sectional study of 315 women, aged between 14 and 44 years, who received perinatal care at the Leonor Mendes de Barros Hospital, in São Paulo, between July 1st, 2019 and October 30th, 2020. The cutoff point suggesting depression was ≥ 12.

    Results

    The screening indicated 62 (19.7%) patients experiencing depression. Low family income, multiparity, fewer prenatal appointments, antecedents of emotional disorders, dissatisfaction with the pregnancy, poor relationship with the partner, and psychological aggression were all risk factors associated with depression in pregnancy or in the immediate postpartum period. Antecedents of depression and psychology aggression during pregnancy were significant variables for predicting perinatal depression in the multivariate analysis.

    Conclusion

    There is a significant association between the occurrence of perinatal depression and the aforementioned psychosocial factors. Screening patients with the EPDS during perinatal and postpartum care could facilitate establishing a line of care to improve the wellbeing of mother and infant.

    Abstract

    Objective

    To characterize and compare the outcomes of omphalocele and gastroschisis from birth to 2 years of follow-up in a recent cohort at a tertiary center.

    Methods

    This is a retrospective clinical record review of all patients with gastroschisis and omphalocele admitted to the Neonatal Intensive Care Unit between January 2009 and December 2019.

    Results

    There were 38 patients, 13 of whom had omphalocele, and 25 of whom had gastroschisis. Associated anomalies were present in 6 patients (46.2%) with omphalocele and in 10 (41.7%) patients with gastroschisis. Compared with patients with omphalocele, those with gastroschisis had younger mothers (24.7 versus 29.6 years; p=0.033), were born earlier (36 versus 37 weeks, p=0.006), had lower birth weight (2365±430.4 versus 2944.2±571.9 g; p=0.001), and had a longer hospital stay (24 versus 9 days, p=0.001). The neonatal survival rate was 92.3% for omphalocele and 91.7% for gastroschisis. Thirty-four patients were followed-up over a median of 24 months; 13 patients with gastroschisis (59.1%) and 8 patients with omphalocele (66.7%) had at least one adverse event, mainly umbilical hernia (27.3% vs 41.7%), intestinal obstruction (31.8% vs 8.3%), or additional surgical interventions (27.3% vs 33.3%).

    Conclusion

    Despite the high proportion of prematurity, low birth weight, and protracted recovery, gastroschisis and omphalocele (without chromosomal abnormalities) may achieve very high survival rates; on the other hand, complications may develop in the first years of life. Thus, a very positive perspective in terms of survival should be transmitted to future parents, but they should also be informed that substantial morbidity may occur in the medium term.
