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.

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.

Revista Brasileira de Ginecologia e Obstetrícia. 2025;47:e-rbgo3
Visualizações196Abstract
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.

Objective:
Preterm birth is a leading global cause of neonatal mortality and morbidity, with oxidative stress playing a role in its pathogenesis. Vitamin C, a powerful antioxidant, may help reduce this risk. This study assessed the effectiveness of vitamin C supplementation, both alone and with vitamin E, in preventing preterm birth compared to a placebo.
Data source:
Databases were systematically searched in PubMed, Cochrane and Embase in December 2023 and updated in May 2024.
Study Selection:
Included RCTs evaluated vitamin C’s effect on preterm birth and related neonatal outcomes.
Data collect:
Statistical analyses used a random-effects model for pooled risk ratios (RR) and 95% confidence intervals (CI). Heterogeneity was assessed with the I² statistic.
Data synthesis:
Seventeen RCTs (21,567 patients) were analyzed. Vitamin C supplementation showed no significant difference compared to placebo for preterm birth (RR 1.04; 95% CI 0.96, 1.14). No significant differences were observed for neonatal death (RR 0.77; 95% CI 0.55, 1.08), NICU admission (RR 1.03; 95% CI 0.95, 1.13), preterm PROM (RR 1.04; 95% CI 0.63, 1.71), or birth weight (MD 52.41; 95% CI −19.65, 124.47). A slight decrease in gestational age was observed (MD 0.26; 95% CI −0.02, 0.55).
Conclusion:
Vitamin C supplementation alone or in combination with vitamin E does not significantly prevent preterm birth or improve related neonatal outcomes.

Objective
The study aimed to determine the level of anemia in pregnant women in the first trimester and in the preconception period by conducting nationwide research.
Methods
The study was designed as retrospective, cross-sectional, and multicenter research. A total of 17 centers from 13 provinces were included in the study. The study was conducted with the participation of two groups of patients who applied to the obstetrics polyclinic between 1 January 2023 and 1 July 2023, who were in the first trimester of pregnancy and who were in the preconception period planning pregnancy.
Results
In total 4,265 women were included in the study. Of these women, 3,884 (91%) were in the first trimester of their pregnancy and 381 (9%) were in the preconception period. Anemia was detected in 24.1% (n=1030) of the patients. Of these patients, 20.6% (n=877) were pregnant women in the first trimester and 3.6% (n=153) were in the preconception period. A statistically significant and positive relationship was found between anemia and meat consumption frequency, educational status, and socioeconomic status of the patients (p=0.000, p=0.000, p=0.000). In addition, a statistically significant and negative correlation was determined between anemia and the number of pregnancies and the parity number (p=0.001, p=0.000) in both groups.
Conclusion
Anemia is a public health problem. Anemia has been determined to be an important problem both in the preconception period and early periods of pregnancy. It is necessary to revise the programs and interventions to reduce the prevalence of anemia and redesign them in line with current conditions.

Visualizações284Ver maisKey points
• Although advances in the treatment of gynecological cancer have improved survival rates, they may also increase the effects of induced menopause, especially in young women.
• Cancer treatments such as oophorectomy, gonadotoxic chemotherapy, and pelvic radiotherapy can induce menopause.
• Gonadotoxic chemotherapy, especially alkylating-containing regimens, often damages ovarian function and may result in permanent menopause.
• Pelvic radiotherapy usually results in permanent loss of ovarian function unless ovarian transposition is performed.
• Diagnosing menopause after cancer is challenging, and common diagnostic criteria such as 12 months or more of amenorrhea and elevated follicle-stimulating hormone (FSH) levels are not entirely reliable, since ovarian function may return years after treatment.
• A multidisciplinary approach to post-cancer menopause is essential and should include an appropriate line of care, since hormone replacement therapy after treatment of gynecologic malignancy is controversial.
