Views88Introduction: the Resolution 196/96 of the Conselho Nacional de Saúde (National Council of Health/Ministry of Health) presents the main Brazilian guidelines on research involving human subjects, including the content of written informed consent. Purpose: to present the knowledge and opinion of Brazilian researchers on the contents of Resolution 196/96, specifically related to the informed consent form. Subjects and methods: forty-six doctors responsible for the area of gynecology at Brazilian universities, four directors of research centers and 31 researchers who participated in a study related to fertility regulation during the 12 months preceding September, 2000. Subjects completed a self-reporting questionnaire. Data were analyzed by the chi² test. Results: most subjects declared that they knew the Resolution 196/96 and considered it adequate, although difficult to comply with; they considered that all studies should have an informed consent form, and knew that its content should guarantee confidentiality. More researchers than those responsible for gynecology department/directors knew that the informed consent form should be prepared by the principal investigator. Significantly more responsible for gynecology department/directors than researchers declared that subjects must always sign (or put their thumb print if they do not know how to write) on the informed consent form. Subjects declared that payment of expenses resulting from participation in a study must always be explained in the informed consent form. Conclusion: despite the wide dissemination of the Resolution 196/96, it was not known by all the researchers nor by all those responsible for gynecology departament/directors. The majority agreed with the contents required by the Resolution for the informed consent form.

Views161See morePurpose: to evaluate p53 overexpression value in vulvar intraepithelial neoplasia (VIN) III recurrence/progression. Methods: twenty patients with undifferentiated VIN III were selected and followed up every six months for four years and divided into two groups: fourteen without and six with recurrence/progression lesion. The recurrence/progression cases were distributed as follows: in three patients recurrence occurred only once; in two, twice, and only one progressed to squamous cancer. In both groups the site of vulvar lesion and p53 overexpression and immunostaining pattern were analyzed. A similar study was performed in recurrence/progression cases, besides the analysis of the time interval to occur the arise of recurrence/progression. Results: recurrence was observed in 25% of the cases and, in 5%, progression to carcinoma. The mean time interval for recurrence was 24.5 months. Multifocal location of the initial lesion was the predominant form (50%) in both groups. In the majority of the cases (87.5%) recurrence/progression occurred at the same site of the initial vulvar lesion. p53 overexpression was observed in 50% of the VIN III primary lesions and in 75% of the recurrence/progression cases. Conclusions: p53 overexpression seems to play an important role in VIN III pathogenesis and may predict the clinical course of the lesions. VIN III recurrence/progression has a tendency to occur in the same area of the initial lesion, suggesting the presence of molecular disturbance.

Views97Purpose: to perform a census about the frequency of endometrial adenocarcinoma of women submitted to diagnostic hysteroscopy in five Brazilian hysteroscopic centers in São Paulo, Rio de Janeiro, Salvador, Caxias do Sul and Porto Alegre. Methods: information was collected from standard questionnaires about the presence of endometrial adenocarcinoma, hysteroscopic staging and histologic type, in pre- and postmenopausal women. Results: among 6,466 hysteroscopic procedures, endometrial adenocarcinoma was present in 92 patients (1.4%), confirmed by histology in 79 (1.2%) cases. For the hysteroscopic diagnosis of endometrial adenocarcinoma confirmed by histology, a sensitivity of 85.9%, specificity of 100%, positive predictive value of 100% and negative predictive value of 98.6% were obtained. In the premenopausal group, among 3,845 hysteroscopic exams, endometrial cancer was present in 83 (3.2%) and confirmed by histology in 71 cases (2.7%). Conclusions: this study points out the importance of epidemiological methods in the diagnostic and prevention programs of endometrial cancer, specially in postmenopause, revealing the need for further epidemiological studies on endometrial adenocarcinoma diagnostis and prevention programs.

Views186See moreAbstract
Objective:
Preterm birth remains a significant contributor to neonatal morbidity and mortality. The use of cervical pessaries as an intervention for preventing preterm delivery in women with a short cervix has been a subject of interest. We evaluated the effectiveness of cervical pessary compared to standard care in preventing preterm delivery in women with a short cervix.
Data source:
Databases were systematically searched in PubMed, Cochrane, and Embase databases in December 2023.
Study selection:
Randomized clinical trials with the outcomes of interest were included.
Data collect:
We computed risk ratios for binary endpoints, with 95% confidence intervals. Heterogeneity was assessed using I2 statistics. Data were analyzed using R software (version 4.3.0). The primary outcomes of interest were preterm delivery before 37 weeks, and preterm delivery before 34 weeks.
Data synthesis:
Seventeen studies with 5,704 patients were included. The use of cervical pessary was associated with a decreased risk of preterm delivery before 37 (RR 0.88; 95% CI 0.81-0.96) and 34 weeks (RR 0.79; 95% CI 0.63-0.99) of gestation in twin pregnancies as compared to standard care without progesterone. There were no significant differences in preterm delivery in singleton pregnancy, neonatal outcomes, preterm premature rupture of the membranes or chorioamnionitis.
Conclusion:
The use of cervical pessary was associated with a significant reduction in preterm delivery at 34 and 37 weeks of gestation in twin pregnancies among patients with a short cervix compared to no treatment. No significant difference was found in singleton pregnancies or maternal outcomes.

Views184See moreAbstract
Objective:
To evaluate the continuation rate, satisfaction, and reasons for discontinuation of depot medroxyprogesterone acetate (DMPA) in adolescents treated in a mental health service.
Methods:
Prospective cohort study conducted in a reference unit for the care of adolescents with mental disorders (MDs) and intellectual disabilities (IDs). All patients received a gynecological consultation and an educational group on contraceptive methods. Sociodemographic data on age, education and gynecological data (menarche, coitarche, regularity of menstrual cycles and presence of symptoms) were collected. Follow-up was quarterly for 12 months, during which symptoms, desire to continue, and satisfaction with the use of the quarterly injectable were assessed.
Results:
Eight hundred and sixty-two sexually active adolescents were supported, 532 adolescents chose to use the quarterly injectable, and 69 of these agreed to participate in the study. The mean age of users was 15.5 years (SD=0.91). After 12 months of follow-up, 34 (49.3%) of the 69 adolescents continued to use the method and 36 (52.3%) were satisfied. Among the 33 (47.8%) who discontinued use, the most common reasons were irregular bleeding and weight gain.
Conclusions:
Adolescents with intellectual disabilities and/or other mental disorders showed a significant rate of continuation and satisfaction with the use of the depot medroxyprogesterone acetate at 12 months, and the most common reasons for discontinuation were irregular uterine bleeding and weight gain.

Objective:
To describe women’s experience of pregnancy during the COVID-19 pandemic.
Methods:
A qualitative study conducted in a private maternity hospital, from May, 2020 to November, 2021, with women aged ≥ 18 years, gestational age ≥ 36 weeks at birth and ≥ 24 hours post-partum. Data collected through semi-structured interviews, recorded, transcribed, and analyzed adopting Krippendorff’s Content Analysis as theoretical-methodological framework.
Results:
Four main themes emerged: Fear, Taking care and celebrating pregnancy: adjusting to the new reality, Harms of Isolation, and Benefits of Isolation. The fear of contamination and its impact on the health of mother and child resulted in the adoption of severe social isolation, including from those considered sources of support by the expecting mother. Overwhelmed, some of the participants reported loneliness and psychic suffering. The opportunity to focus on the pregnancy, the preparations for the arrival of the child, and the family made isolation a beneficial and positive period for other women.
Conclusion:
The experience of pregnancy in the Pandemic was an event outside of the ordinary and common. The expecting mother faced her worst fears on a daily basis and attended prenatal care, in order to ensure her child would be born healthy. The celebration of the baby’s life, amid so many deaths, had to be adjusted to the virtual environment. It was a tense, solitary, and ambiguous period, which demanded a lot from the mental health of some participants, but to others, brought advantages that would not have been possible in different times.

Original ArticleEffect of COVID-19 on Brazilian cesarean and prematurity rates: a cross-sectional study
Revista Brasileira de Ginecologia e Obstetrícia. 2025;47:e-rbgo6
Views181See moreAbstract
Objective:
To investigate the relationship between prematurity and cesarean section rate in Brazil during the beginning of COVID-19 pandemic.
Methods:
Utilizing the Robson Classification, this study analyzed data from the Brazilian Ministry of Health’s Live Births Panel, comparing CSR) and group 10 (preterm deliveries) between 2019 (pre-pandemic) and 2021 (pandemic) in each of Brazilian states and the overall country. The prematurity and CSR were compared using prevalence ratio and confidence interval, and p-value was obtained. The variation of prematurity and CSR were compared through the coefficient of determination (R2).
Results:
A total of 5,522,910 deliveries were evaluated during the period. The CSR increased from 56.34% to 57.05% (p<0.01), and the frequency of preterm deliveries rose from 8.99% to 9.13% (p<0.01). The CSR increased in 23 States and decreased in 4 States, while the prematurity rate increased in 16 States and decreased in 10 States. A positive relationship between the increase of CSR and prematurity was observed during COVID-19, with an R2 value of 0.3121, suggesting a moderate association between these two variables.
Conclusion:
Between 2019 (pre-COVID-19 pandemic) and 2021 (the first full year of the COVID-19 pandemic), there was an increase in prematurity and CSR in Brazil. These increases were observed in most Brazilian states and may be correlated. However, it is impossible to establish a cause-effect relationship given the design of this study.

Original ArticleAccurate evaluation of mode of delivery and labor progression with angle of progression: a prospective cross-sectional
Revista Brasileira de Ginecologia e Obstetrícia. 2025;47:e-rbgo5
Views169See moreAbstract
Objective:
To determine the validity of the angle of progression (AoP) in predicting delivery mode among women in the second stage of labor.
Designs:
This prospective cohort study was conducted at the Obstetrics and Gynecology unit (OBGYN) of two hospitals in Vietnam. Transperineal ultrasound was performed for each woman to measure the progression angle in the second phase of labor.
Participants:
A total of 725 women with singleton pregnancies with cephalic presentation at term
Methods:
Transperineal ultrasound was used to measure the angle of progression in the second labor phase and to identify the delivery method.
Results:
The rate of vaginal birth in women with an AoP ≥ 120° on transperineal ultrasound was 70.2%. The optimal cutoff point of AOP ≥122° with sensitivity and specificity for vaginal birth were 87.8% and 80.7%, respectively the area under the ROC curve of 0.887 (p<0.0001). The study's sample size was restricted owing to deficiencies in resources and time.
Conclusion:
The likelihood of achieving spontaneous vaginal delivery can be predicted by the angle of progression measured with transperineal intrapartum ultrasonography during the second stage of labor in women.

Views146Abstract
Objective:
This study aimed to verify the relation between gastrin-releasing peptide receptor (GRPR), oncogenic Human Papillomavirus (HPV) and cervical lesions severity.
Methods:
GRPR mRNA levels were evaluated in cervical cancer-derived cell lines and in primary keratinocytes expressing HPV16 oncogenes by RT-PCR. GRPR protein expression was assessed by immunohistochemistry in organotypic cell cultures derived from keratinocytes transduced with HPV16 oncogenes and in 208 cervical samples, including 59 non-neoplastic tissue, 28 cervical intraepithelial neoplasia grade 3 (CIN3), 44 squamous cell carcinomas (SCC) and 77 adenocarcinomas (ADC). Generic primers (GP5+/GP6+) were used to identify HPV infection in tissue samples. Experiments involving cell lines were analyzed through non-parametric tests (Kruskal Wallis), and Fisher’s Exact Test for human tissues samples. All statistical tests were considered significant at p <0.05. Immunohistochemical evaluation was conducted independently and blindly by two observers (AD- LO). Any discordant findings were resolved through discussion to reach a consensus score.
Results:
GRPR mRNA levels were not increased in cells expressing HPV16 or HPV18 oncogenes. However, at the protein level, GRPR was upregulated in organotypic cell cultures containing HPV oncogenes. Besides, it was identified an association between GRPR expression and cervical lesion severity (p < 0.0001). The detection rate of high-risk HPV DNA was directly correlated with cervical disease. Nonetheless, HPV infection was not directly associated with GRPR in cervical samples.
Conclusion:
GRPR expression is highly predictive of cervical lesion severity, irrespective of HPV infection and might contribute to improving patient’s therapeutic management as well as being used a marker of disease progression.

Views166Abstract
Objective:
This study aimed to investigate the effect of low-level laser therapy (LLLT) on nipple trauma and pain during breastfeeding through a systematic review with a meta-analysis of selected studies.
Source of the data:
A thorough search was conducted on March 22, 2022, using the databases PubMed, SciELO, LILACS, PEDro, CINAHL, EMBASE, ScienceDirect, Scopus, Google Scholar, MEDLINE, the Cochrane Library, Clinical Trials, Web of Science, TRIP, DARE, and ProQuest. The search terms included various combinations of low-level laser therapy, nipple pain, nipple trauma, and breastfeeding.
Studies selection:
Out of 107 articles identified, only three controlled and randomized clinical trials was included. The extracted data encompassed breast and trauma characteristics, treatment types, outcomes (pain and healing process), evaluation tools, LLLT usage, laser brand, and parameters.
Data collection:
Data extraction was performed using RAYYAN for systematic reviews. The risk of bias in the studies was evaluated.
Data synthesis:
Pain was measured using the visual analog scale (VAS). The included studies did not use validated tools for assessing physical conditions. All studies employed LLLT with a 660-nm wavelength, though there were variations in equipment power, energy dose, and application methods. The meta-analysis revealed an average difference of −0.60 points (95% CI: −1.52 to 0.31) in the VAS pain scores between the LLLT and control groups. No heterogeneity was observed among the studies (I2=0%), indicating no significant difference in pain relief between LLLT (red light) and control groups.
Conclusion:
LLLT may offer a promising option for managing breastfeeding-related complications, though further research is required.

Statins are the most widely used pharmacological class for treating hyperlipidemia, although they are contraindicated during pregnancy. This study aims to demonstrate the clinical effects of statins in pregnant women through an interactive review. Fifteen original articles were selected, in English or Portuguese, within of five years. Statins have not been associated with the development of fetal malformations and their use may be useful in preventing unfavorable cardiovascular outcomes, with the potential to reduce oxidative stress and angiogenic dysfunction. However, the use of statins to prevent pre-eclampsia in humans has not been properly clarified and further studies are needed. Pravastatin is considered safer than statins for use during pregnancy.

Views81See moreKey points
•Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) is the leading cause of vaginal agenesis.
•It is characterized by primary amenorrhea with typical adrenarche and telarche and may be associated with congenital urological and skeletal conditions that should be investigated.
•Differential diagnoses include: vaginal obstructions (imperforate hymen, distal vaginal atresia, transverse vaginal septum), uterine obstructions (cervical atresia), and differences in sexual development (gonadal dysgenesis, complete androgen insensitivity and congenital adrenal hyperplasia due to CYP17 deficiency).
•Laboratory tests (testosterone, follicle-stimulating hormone [FSH] and karyotype) and radiological tests (pelvic ultrasound and MRI) are necessary.
•Vaginal dilation is the first line of treatment with high success rates.

Objective:
To evaluate anxiety, depression, sexual function and quality of life in women with hyperprolactinemia.
Methods:
Cross-sectional study with 80 women divided into two groups: 30 women with hyperprolactinemia (Study Group) followed and treated at the endocrine gynecology outpatient clinic and 50 women without hyperprolactinemia, with regular menstrual cycles (Control Group) followed at the family planning outpatient clinic of the State University of Campinas from June 2021 to October 2022. Sociodemographic characteristics, quality of life (SF-36 Questionnaire), sexual function (Female Sexual Function Index Questionnaire), depression (Beck Depression Inventory) and anxiety (Beck Anxiety Scale) were evaluated in both groups. Categorical variables were described as absolute frequency and percentage; numerical variables as mean and standard deviation. Comparison of numerical variables between two groups was performed by Mann-Whitney test, while categorical were compared by Chi-Square or Fisher’s exact tests.
Results:
The mean age of women with hyperprolactinemia was 39.6±8.1 years and the Control Group was 31.2±9.5 years (p<0.001). There was no difference in anxiety scores (p=0.66), depression (p=0.08) and general sexual function (p=0.08) in both groups. However, women with hyperprolactinemia had lower scores in the domains of pain and arousal and worse functional capacity than Control Group (p<0.05).
Conclusion:
Women with hyperprolactinemia under treatment do not show any impairment in their anxiety, depression and sexual function when compared to women without hyperprolactinemia. However, analysis of quality of life showed that women with hyperprolactinemia have poor functional capacity.

Objective:
Analyze the hysterectomy rates per resident in graduation year in teaching hospitals in the state of São Paulo (Brazil).
Methods:
We selected teaching hospitals in the state of São Paulo and gathered information from two public databases to estimate the hysterectomy rates per resident in their final year of training between 2009 and 2019.
Results:
Between 2009 and 2019, there was a 37.5% increase in the number of residents in their final year of training, a 4.31% increase in the number of hysterectomies, and a drop in the hysterectomy rates per resident of 24.1%. The reduction of the rate of hysterectomy per resident was more pronounced for vaginal route (46.4%) followed by abdominal route (23.3%). The ratio of laparoscopic hysterectomy per resident increased 264% during the period, however, this route was used in only 7% of the surgeries in 2019.
Conclusions:
The hysterectomy rates per resident in their final year of training showed a notable reduction. This trend, particularly pronounced in vaginal and abdominal routes, signals a shift towards minimally invasive techniques.

Objective:
This study aimed to evaluate the prevalence of antiphospholipid syndrome (APS) among women experiencing recurrent pregnancy loss (RPL).
Methods:
A cross-sectional was conducted, reviewing the medical records of 134 women with a history of two or more miscarriages, treated between January 2014 and May 2024 at a tertiary university center in Belo Horizonte, Brazil. APS screening was performed by assessing anticardiolipin (IgG and IgM), lupus anticoagulant, and anti-β2-glycoprotein-1 (IgG and IgM) antibodies, based on Sapporo criteria. All tests were performed during non-pregnant periods and at least 12 weeks after the last miscarriage.
Results:
The study included 134 women with a mean age of 33.8 ± 5.7 years. The number of prior miscarriages ranged from 2 to 11 per couple. Among the patients who presented the lupus anticoagulant, only two (1.49%) tested positive in two samples, as per revised Sapporo criteria. Considering IgG and IgM anticardiolipin antibodies, four patients (2.98%) tested positive in two samples according to old Sapporo criteria, with one patient having a positive IgG test in two samples, two having positive IgM in two samples and a single patient having both positive tests. None of the 56 patients tested positive for anti-β2-glycoprotein-1 antibodies in two samples.
Conclusion:
The prevalence of antiphospholipid antibodies, in line with revised Sapporo criteria, is low among Brazilian women with recurrent pregnancy loss, consistent with recent studies in literature. Ensuring the appropriateness of diagnostic criteria is crucial to avoid unnecessary treatment with platelet anticoagulants and heparin in this population.

Views113Abstract
Objective:
In vitro, fertilization is the primary treatment method for infertility. Follicular fluid analysis is an approach used to optimize the results of assisted reproductive techniques. Oxidative stress represents the imbalance between the production of reactive oxygen species and their detoxification. Total Antioxidant and Oxidant Status, and Oxidative Stress Index levels are the main oxidative stress markers. This study investigated the effects of oxidative stress markers on infertility etiology, embryo quality, and success of In vitro fertilization.
Methods:
Before enrolling in the ICSI-ET cycle, participants had their FSH and LH levels assessed on the second day of the cycle. The ovarian degrees of the participants were evaluated by transvaginal ultrasonography. Participants underwent controlled ovarian stimulation using the GnRH antagonist protocol. TV-USG and serial E2 measurements were performed at appropriate intervals to follow follicular development. Follicle sizes, quantity, and endometrial thickness were recorded. Total Antioxidant and Oxidant Status, and Oxidative analyses were conducted using Rel Assay Diagnostics Assay Kits.
Results:
The average number of total oocytes in the participants was 10.25±6.66, and the average of mature M2 stage oocytes was 6.71±3.72. The average number of fertilized oocytes was 4.65±2.81. Fertilization rates were calculated as approximately 54.75±25.58%. A statistically significant positive correlation was found between embryo quality and serum Total Antioxidant Status levels (p=0.004). Similarly, a significant positive correlation was observed between embryo quality and follicular Total Antioxidant Status values (r = 0.42, p = 0.01).
Conclusion:
This study concluded that oxidative stress markers affect certain stages of the IVF treatment process.

Objective:
We aimed to compare the efficacy and safety of letrozole and clomiphene versus letrozole alone for ovulation induction in patients with Polycystic Ovary Syndrome (PCOS).
Data Sources:
We systematically searched EMBASE, PubMed, and Cochrane databases on October 31, 2024.
Study selection:
We included studies of women with PCOS treated with a combination of clomiphene and letrozole or letrozole alone to induce ovulation that reported any of the outcomes of interest, namely rate of mature follicles and ovulation, ovulation, pregnancy, miscarriages, endometrial thickness, and number of mature follicles.
Data collection:
We pooled odds ratios (OR) and mean difference (MD) with 95% confidence intervals (CI) using a random effects model using R statistical software, version 4.2.1. Heterogeneity was assessed with I statistics, and a random effects model was used.
Data Synthesis:
Four RCTs and two observational studies comprising 592 patients were included. Combined therapy was associated with a higher rate of a mature follicle (OR 2.74; 95% CI 1.72-4.37; p< 0.001; I=0%) and ovulation (OR 2.55; 95% CI 1.57-4.12; p< 0.001; I=35.9%). The number of mature follicles, number of pregnancies, thickness of endometrial lining, and the incidence of adverse events, including headache, abdominal bloating, fatigue, back pain, breast discomfort, and night sweats, were similar between groups.
Conclusion:
In women with anovulatory infertility secondary to PCOS, letrozole and clomiphene citrate combined therapy was associated with improved mature follicle and ovulation rates, with a similar safety profile compared to letrozole alone. However, no significant impact was observed on pregnancy rates.

Objective:
This study aimed to assess the incidence of small for gestational age (SGA) newborns in pregnant women infected with COVID-19 and examine the associated neonatal outcomes.
Methods:
This study involved a secondary analysis of the REBRACO Network, a prospective cohort study conducted in 15 maternity hospitals in Brazil before the introduction of COVID-19 vaccination (February 2020 to February 2021). Demographic data of pregnant women tested for COVID-19 were analyzed, and fetal outcomes were compared between women with positive and negative COVID-19 results who had SGA fetuses.
Results:
A total of 729 symptomatic pregnant women with COVID-19 were included in the study. However, there were 248 participants with missing information regarding childbirth or loss of follow-up, and 107 participants without confirmatory tests for COVID-19. Among the remaining participants, 198 had confirmed COVID-19 and 176 tested negative. The incidence of SGA among women with COVID-19 was 22.4%, whereas the incidence among women who tested negative for COVID-19 was 14.8%. SGA newborns born to COVID-19 positive pregnant women were 1.6 times more likely to experience adverse outcomes (such as prematurity, stillbirth, neonatal death, and admission to a neonatal ICU) compared to non-SGA newborns [OR = 1.655 (1.145 – 2.394); P=0.017]. In SGA newborns of pregnant women with confirmed COVID-19 infection, mechanical ventilation use was found to be associated with the infection [OR = 0.692 (0.562 – 0.853); P=0.002].
Conclusion:
The higher incidence of SGA newborns and its stronger association with prematurity in pregnant women with confirmed COVID-19 infection suggest that COVID-19 infection is a significant factor contributing to neonatal morbidity and mortality.

Objective:
This umbrella review aimed to synthesize evidence from systematic reviews of clinical trials on the efficacy of tranexamic acid in gynecology and obstetrics procedures.
Methods:
We searched Medline, Embase, SciELO and Cochrane Database of Systematic Reviews on March 11, 2024, using the term “tranexamic acid”. Four reviewers independently select studies and extract data. We assessed the quality of systematic review and the quality of evidence, using AMSTAR 2 and GRADE tools, respectively.
Results:
Of 651 systematic reviews identified, 16 reviews with 96663 patients were included. The surgical procedures were cesarean section, myomectomy, hysterectomy, and cervical intraepithelial neoplasia surgery. All reviews showed a statistically significant and clinically relevant reduction in intraoperative and post-procedure blood loss, associated with intravenous or topical use of tranexamic acid. Tranexamic acid resulted in a significant reduction in the need for blood transfusions and a less pronounced drop in postoperative hematocrit and hemoglobin levels in cesarean section. Several reviews addressed the same question, but the number of included trials varied substantially, which might indicate flaws in search and selection of studies of these reviews. The quality of systematic reviews was low or critically low, and the quality of evidence was moderate.
Conclusions:
This umbrella review shows that tranexamic acid can reduce blood loss and hemorrhage in gynecology and obstetrics procedures. High quality systematic reviews are still needed.
