RESUMO
Background: The research combined different bibliometric techniques to analyze systematically recurrent pregnancy loss (RPL) documents from 1970 to 2023. Methods: Overall, 1287 documents from the Web of Science database associated with recurrent pregnancy loss between 1970 and 2023 were identified for more than 300 journals. The data were analyzed with VOSviewer software. Results: The trend of paying attention to the topic of RPL can be divided into three periods. The number of publications on RPL increased significantly after 2010. Most of the papers were published in Obstetrics and Gynecology and Reproductive Biology areas. Utilizing co-occurrence and co-citation analysis, our study found that the most influential documents mapped the knowledge structure, and projected future research directions. The co-occurrence analysis showed five clusters even though the co-citation analysis designates four. Conclusion: RPL has increased in recent years exponentially and some areas were explained carefully, therefore these results could be used as a research agenda for the future direction by a range of interested beneficiaries.
RESUMO
Background: The recognized role of Anti-Müllerian hormone (AMH) as a marker for women's biological age and ovarian reserve prompts debate on its efficacy in predicting oocyte quality during IVF/ICSI. Recent findings challenging this view compelled us to conduct this study to examine the correlation between AMH levels and quantity/quality of oocytes in IVF/ICSI procedures. Methods: The data were collected retrospectively from the medical records of 320 women between 25-42 years old. The included patients were divided into two groups: the high AMH group (>1.1 ng/ml) and the low AMH (=<1.1 ng/ml) group. The high AMH group comprised 213 patients, while the low AMH group consisted of 107 patients. Spearman's correlation coefficient and Multinomial logistic regression were computed to assess the relationships between different variables. Results: Significant positive correlations were detected between AMH level and the number of aspirated follicles (rho=0.741, p<0.001), retrieved oocytes (rho=0.659, p<0.001), M2 oocytes (rho=0.624, p<0.001), grade A embryos (rho=0.419, p<0.001), and grade AB embryos (rho=0.446, p<0.001. In contrast, AMH levels had negative associations with the number and duration of cycles (p<0.05). AMH emerged as a statistically significant independent predictor of the number of M2 oocytes. Conclusions: Serum AMH level could represent the quantity and quality of oocytes following IVF/ICSI treatments. Future studies should aim to delve deeper into the correlations between AMH levels and both the quality and quantity of embryos. Additionally, it would be beneficial to consider the influence of sperm factors, as well as assess pregnancy rates.
RESUMO
Objective: This study aimed to measure the correlation of sperm DNA fragmentation with semen parameters, lifestyle, and fertility outcomes after intracytoplasmic injection (ICSI). Materials and methods: The partners who were candidates for ICSI with a history of one In vitro fertilization (IVF) failure or male factor were recruited in the study. Semen parameters including sperm count, motility, and morphology as well as DNA fragmentation index (DFI) (that were divided into 2 groups as high (>15%), and low (≤15%) fragmentation scales) were evaluated either. The correlation of DFI with semen parameters, lifestyle, and clinical pregnancy after ICSI were compared between groups. Results: In 120 included couples, 59 men (49.2%) had DFIs ≤ 15% and 61 (50.8%) cases had DFIs >15%. In the group with higher DFI, abnormal morphology (p=0.010) was higher whereas, progressive motility (p=0.001), total motility (p<0.001), and total count (p<0.001) of sperm were significantly lower. In addition, the DFI was significantly higher in the subgroup of male infertility (0.012). Logistic regression showed that a lower risk of DFI>15% was associated with higher values of progressive motility (OR=0.97, p=0.001), total motility (OR=0.96, p=<0.001), count (OR=0.96, p=<0.001) and even clinical pregnancy (OR=0.27, p=0.011). However, a history of testicular surgery was associated with a higher risk of DFI>15% (OR=3.37, p=0.046). Although no correlation was found between male age and lifestyle components with DFI, the number of embryos was lower in DFI≥15% (p<0.001). Conclusion: DFI provide a clinically important measurement of sperm quality and have an impact on IVF outcomes; however, lifestyle components may not correlate with DFI.
RESUMO
BACKGROUND: Digital Polymerase Chain Reaction (dPCR) presents a promising approach for quantifying DNA and analyzing copy number variants, particularly in non-invasive prenatal testing. This method offers a streamlined and time-efficient procedure in contrast to the widely used next-generation sequencing for non-invasive prenatal testing. Studies have reported encouraging results for dPCR in detecting fetal autosomal aneuploidies. Consequently, this systematic review aimed to evaluate the effectiveness of dPCR in screening for trisomy 21, 18, and 13. METHODS: A systematic search was conducted in PubMed, Web of Sciences, and Embase for relevant articles published up to December 30, 2023. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was utilized for the quality assessment of the included articles. Furthermore, a bivariate random-effect regression model was used to conduct a meta-analysis on the utility of dPCR for trisomy 21 screening. RESULTS: A total of 9 articles were included in this review, with all of them assessing the utility of dPCR in trisomy 21 screening, and 2 and 1 studies conducting additional analysis on the screening abilities of dPCR for trisomy 18 and 13, respectively. A bivariate random-effects model calculated pooled sensitivity and specificity with a 95% confidence interval (CI). Meta-analysis of 6 studies comparing trisomy-21 screening with karyotyping demonstrated dPCR's pooled sensitivity of 98% [95% CI: 94 -100] and specificity of 99% [95% CI: 99 -100]. While conducting a meta-analysis for trisomy 13 and 18 proved impractical, reported values for sensitivity and specificity were favorable. CONCLUSIONS: These findings suggest that dPCR holds promise as an effective tool for non-invasive prenatal testing, presenting a less time-consuming and intricate alternative to next-generation sequencing. However, further research is necessary to evaluate dPCR's applicability in clinical settings and to delineate its specific advantages over next-generation sequencing. This study contributes valuable insights into the potential of dPCR for enhancing prenatal screening methodologies. TRIAL REGISTRATION: The protocol of this study was registered in the International Prospective Register of Systematic Reviews (PROSPERO) on 7/3/2024, with a registration code of CRD42024517523.

Key Clinical Message: Placenta previa, accompanied by placenta percreta, which involves invasion of the bladder, presents a significant risk of excessive bleeding during and after delivery. This case highlights that prophylactic embolization, conservative surgery, and careful monitoring offer an effective approach to avoid hysterectomy in cases of placenta percreta with adjacent organ involvement. Abstract: Placenta previa complicated by placenta percreta is associated with a high risk of massive intra and post-partum hemorrhage. We present a case of a 35-year-old woman (G2 P1) who was referred to the Akbar-Abadi hospital at 13 weeks of gestation. Color Doppler ultrasound indicated complete placenta previa-percreta with bladder invasion. After induction of fetal demise, bilateral uterine and bladder artery endovascular embolization was conducted for the patient. After 48 h, under ultrasound guidance, surgical resection of residual percreta tissue was conducted as much as possible. Eight weeks later, a follow-up sonography showed the minimum residual placenta tissue and she regained menstrual cycles after 2 months. This case indicated that the combination of prophylactic embolization, conservative surgical management with placenta left in situ, and follow-up with serial color Doppler monitoring, is an optimum method to avoid hysterectomy in placenta percreta patient with adjacent organ invasion.
RESUMO
BACKGROUND: Fetal movement monitoring is one of the strategies used to assess the fetus's health. Until now, most studies focused on the decreased fetal movement and neonatal outcome, although this systematic review and meta-analysis is designed to assess the association between increased fetal movements (IFM) with perinatal outcomes. METHOD: The electronic databases including PubMed, Scopus, Web of Science, and EMBASE were systematically searched for studies investigating the perinatal outcome of women with increased fetal movements from inception to July 2023. Following that, a random-effect meta-analysis model was used to obtain the combined diagnostic and predictive parameters including perinatal mortality (still birth and early neonatal mortality), operative delivery, Apgar score, neonatal resuscitation at birth and NICU Admission. RESULTS: After the initial screening, seven studies examining the association between increased third trimester fetal movement and various perinatal outcomes were included. Meta-analysis revealed a significant reduction in the risk of cesarean delivery among patients with IFM compared to controls, suggesting a potential protective effect during childbirth. However, no statistically significant difference was observed in birth weight, small or large for gestational age births, neonatal intensive care unit admission, maternal age, umbilical cord around the neck, gestational diabetes mellitus, and hypertension, indicating that IFM may not be a major predictor of adverse perinatal outcomes or maternal conditions. Notably, IFM was significantly associated with a higher likelihood of labor induction. CONCLUSION: The findings suggest that IFM may have a protective effect against cesarean delivery. Additionally, IFM does not appear to be significantly associated with maternal age, umbilical cord around the neck, gestational diabetes mellitus and hypertension. However, the observed significant association with labor induction warrants further investigation.

Background: Pre-eclampsia (PE) is a multiorgan disorder that affects 2-5% of all pregnant women. Present recommendations for when to start aspirin in high-risk women are after 11 wk of gestation. Objective: We present a protocol to investigate the effectiveness of aspirin use from early pregnancy, which is a randomized controlled trial to assess whether prescribed low-dose aspirin from early pregnancy reduces the prevalence of early and late-onset PE. Additionally, to compare the effectiveness of aspirin administration before and after 11 wk in reducing the occurrence of PE? Materials and Methods: All pregnancies at risk of PE, according to demographic and midwifery history, who are referred to the Maternal-Fetal Clinic of Tehran University hospital, Tehran, Iran were invited to take part in the trial. The outcomes of pregnancy and newborns will be gathered and analyzed. The first registration for the pilot study was in January 2023, and the participants were recognized as high-risk for PE. In addition, enrollment in the main study will begin as of October 2023.
RESUMO
Objective: The objective of this study was to evaluate the effectiveness of structured workshops in improving the knowledge and skills of obstetrics and gynecology residents for repairing high-grade perineal lacerations. Materials and methods: This quasi-experimental multicenter study evaluated the baseline knowledge of obstetrics and gynecology residents using an online patient-management problem (PMP) tool. After the initial evaluation, a workshop was conducted using sponge models to teach the practical technique for repairing high-grade perineal lacerations, including external and internal anal sphincter repair. The residents' knowledge was reassessed by PMP exams at 3 and 6 months after the workshop, and the scores were compared to the baseline statistics. Result: Eighty residents participated in the study, including 26, 22, and 32 at the first, second, and third-year levels of residency, respectively. The total PMP scores significantly improved after three months of the workshop, with an increasing total score from 15.5 (baseline) to 31.3 (p = 0.027) (range of total score from - 63 to + 52). The senior residents performed better before and after three months of the intervention. However, in the six-month follow-up, the total PMP score of all residents decreased to 12.3 with no significant difference with pre-education scores at all levels. Similar significant results were also reported for each PMP question at all levels of residency. Conclusion: The study found that obstetrics and gynecology residents had substandard knowledge in repairing perineal lacerations. Although the training workshop significantly increased residents' knowledge, its effectiveness diminished over time, indicating a need for continuous or periodic training.

RESUMO
BACKGROUND: This study aims to document a woman's external genitalia data in the form of a labiogram and investigate whether variations in the size of specific components of a woman's external genitalia can influence her overall satisfaction with the esthetic appearance of her genitalia. METHODS: A cross-sectional observational study was carried out on a sample of 500 Iranian women. Socio-demographic information was collected for all participants, and they completed the Female Genital Self-Image Scale (FGSIS) questionnaire. Measurements of different external genitalia components were obtained for all participants. RESULTS: The findings revealed that there was no significant association between the measurements of the external genitalia and age or BMI. However, a significant negative correlation was observed between the total score on the FGSIS and specific parameters related to the width of different sections of the labia minora. The correlations were as follows: left lower third (r = - 0.305), lower right third (r = - 0.302), left middle third (r = - 0.365), right middle third (r = - 0.435), left upper third (r = - 0.397), and right upper third (r = - 0.407) (P value< 0.001). Moreover, cutoff points of 1.95 cm on the left side and 1.90 cm on the right side were identified through analysis as thresholds for predicting dissatisfaction among women. CONCLUSION: This study suggests that the width of the labia minora might influence certain women's motivation to undergo labiaplasty, a surgical procedure designed to modify the labia minora. To help women make informed decisions, it is crucial for those considering the procedure to have a comprehensive understanding of different labia minora types, potential benefits, and associated risks. By being well-informed, individuals can make choices that align with their personal preferences and priorities.

BACKGROUND: The objective of this study is to evaluate the legal proceedings that arise from Female Genital Cosmetic Surgeries (FGCS) and analyze the reasons why women file complaints against their surgeons. Additionally, we examined the outcomes of the legal decisions associated with these complaints. METHODS: This descriptive cross-sectional study was conducted in Tehran province, Iran, from 2012 to 2021. The primary data source for this study was forensic medical records, which were reviewed to gather relevant information. The collected data included the characteristics of the participants, the reasons for lawsuits, the procedure setting, and the outcomes of the legal decisions. RESULTS: A total of 121 patients were examined in the study, revealing that Labiaplasty was the most prevalent procedure (49.6%), followed by vaginoplasty (19.8%) and perineoplasty (13.2%). The most common complaints were related to cosmetic concerns (57%), lack of recovery (26.4%), and sexual dysfunctions (22.3%). Healthcare providers were found liable for malpractice in 52.1% of cases. Additionally, having the surgery performed by a gynecologist decreased the risk of malpractice (ß = 0.21, p= 0.034), while procedures in private clinics increased the risk (ß = 2.95, p = 0.040). CONCLUSION: The study's findings emphasized the importance of providing women with comprehensive education and consultations to ensure they are well-informed about the potential outcomes and risks of FGCS. Furthermore, the study highlighted the significance of having these surgical procedures performed by skilled and experienced surgeons.

OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the diagnostic value of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in women with a history of abortion (missed and threatened) and recurrent pregnancy loss (RPL) in comparison with healthy pregnancies. METHODS: Electronic databases including MEDLINE, Scopus, Web of Science, Embase, and Cochrane Library were searched for NLR and PLR in women who experienced early pregnancy loss up to January 1, 2023 with a combination of proper keywords. Meta-analysis was done for comparison with three or more studies and summary estimates were measured. RESULTS: A total of 390 citations were retrieved initially, and after screening, 16 articles were deemed eligible for the final review. Among these, 14 studies underwent meta-analysis. The meta-analysis revealed that the standard mean of the NLR was significantly higher in abortion cases compared to the control group. However, there was no significant difference in the PLR between the pregnancy loss group and the control group. CONCLUSION: NLR was significantly higher among RPL patients compared to the control group, according to these data, NLR may be capable of being used in the diagnosis of RPL as an easy, cheap, and accessible modality. Further studies, which take these variables into account, will need to be undertaken to determine the diagnostic value of NLR and PLR in early pregnancy loss.

INTRODUCTION: Episiotomy is a procedure during vaginal delivery to facilitate a safer delivery. However, it can also have complications including hemorrhage, perineal tears, infections, and vaginal hematoma which should be managed and monitored carefully. PRESENTATION OF CASE: A 27-year-old woman with term pregnancy, had a normal vaginal delivery at 39 weeks of gestation, and a large episiotomy was performed due to the estimated neonate weight to prevent shoulder dystocia. She was complicated with a huge pelvic hematoma that was expanded to prerenal space. DISCUSSION: This complication was managed by conservative therapy, including antibiotic therapy, intensive observation of the patient's situation, and follow-up with a CT scan after consulting with a radiologist. The huge hematoma was reduced. CONCLUSION: Noninvasive management and close monitoring for pelvic hematoma due to episiotomy in a low-risk patient are successful; however, consulting with radiologists and experts and a multidisciplinary approach should be considered.
RESUMO
Infertility is a significant problem influencing many couples. Our purpose was to assess the field of infertility in Obstetrics and Gynecology from 1955 to 2022 reviewing 3575 documents found in the Web of Science database. Most articles were in the areas of Reproductive Biology, Fertility, Endometriosis & Hysterectomy, and Chromosome Disorders. We found publication has increased dramatically since 1989. Agarwal, Thomas, and Sharma; United States, England, and Canada; Fertility and Sterility, Human Reproduction, and AJOG were the most-cited authors, countries, and journals, respectively. We discovered five substantive clusters: male infertility factors, female infertility factors, causes and treatment of infertility, the consequence of infertility, and assisted reproductive techniques. Using bibliometric review (Co-citation analysis) six research areas were found: semen analysis and sperm morphology, regional differences in the psychological effects of infertility, unexplained infertility, endometriosis, diagnosis and treatment of infertility, and polycystic ovary syndrome. Despite advances in understanding infertility, further research is needed.
RESUMO
OBJECTIVE: The current study aims to evaluate the impact of COVID-19 infection and vaccination on ovarian reserve by detecting the anti-Mullerian hormone (AMH) level. METHOD: PubMed, Embase, Web of Science, and Scopus has been searched for studies assessing the effect of COVID-19 infection and/or vaccination on AMH levels up to February 27, 2023. Based on PRISMA 2020 statement criteria, a systematic review and meta-analysis of included studies were performed. The studies' quality was assessed by the National Institute of Health (NIH) quality assessment tool. The standardized mean difference (MD) of the AMH level was used and the quantitative values of each study were pooled separately by using a random effect model. RESULTS: Out of 246 studies screened, 18 were included in the systematic review and 14 in the meta-analysis. Included studies were published between 2021 and 2022 and were conducted in different countries, including the USA (n = 3), China (n = 2), Russia (n = 2), Turkey (n = 5), Israel (n = 3), Czech (n = 2), and Spain (n = 1). Eight studies investigated the effect of SARS-CoV-2 infection on AMH levels, and ten studies investigated the possible effect of COVID-19 vaccination on AMH levels. The pooled analysis showed a statistically significant decrease in AMH levels after COVID-19 infection (SMD: -0.24; 95% CI: -0.36 to -0.11; I2 = 0%; p = .0003). Vaccination analysis showed a nonstatistically significant change in AMH levels after COVID-19 vaccination (SMD: -0.11; 95% CI: -0.25 to 0.04; I2 = 35%; p = .14). CONCLUSION: COVID-19 infection can result in ovarian reserve injury by reducing the AMH level but getting vaccinated against COVID-19 has no impact on the AMH level.

Due to the definitive known effect of magnesium on insulin resistance and the fact that insulin resistance is a main etiology in polycystic ovary syndrome (PCOS), it is assumed the use of magnesium supplements can improve insulin resistance, lipid profiles, and glucose and thus may also play a role in improving the clinical condition of patients with PCOS. We aimed to assess the effects of magnesium supplements on anthropometric, clinical, and metabolic parameters in women suffering from PCOS. This triple-blind randomized clinical trial study was conducted on women aged 15-35 years with PCOS. The patients were randomly assigned to receive a magnesium oxide supplement (250 mg/day for 2 months) or a placebo. The study parameters were evaluated and compared between two groups before as well as 2 months and 5 months after the initial assessment. In total, 40 cases (20 in each group) were recruited in the study. A significant reduction in the serum insulin level (P-value = 0.036) and insulin resistance (p-value = 0.032) was observed in the case group. Prescribing magnesium supplements could also lead to lowering total cholesterol, low-density lipoprotein, and fasting blood sugar along with increasing the level of high-density lipoprotein. We could not find any significant difference in anthropometric parameters as well as the mean systolic and diastolic blood pressures before and after intervention between the two groups. Although the rate of oligomenorrhea significantly decreased in the two study groups, it was no different across the two groups before and also after the intervention. The use of magnesium supplements in patients with PCO, regardless of the etiology or progression of the disease, can greatly improve the metabolic status of these patients by improving insulin resistance and modulating the level of lipid profile.

INTRODUCTION: This study aimed to evaluate the potential value of placental anatomic features and various types of normal and abnormal cord insertion types in predicting adverse maternal-fetal outcomes in singleton pregnancies. We also tried to assess the association between these outcomes and various types of placental cord insertion. METHOD: This prospective observational study was performed on singleton pregnancies. For each patient placental features including diameter, thickness, type of cord insertion, and the shortest distance between the cord insertion point and placental edge were recorded. The relationship between these factors and the development of multiple adverse pregnancy outcomes including preterm labor, intrauterine fetal death (IUFD), and the rate of neonatal intensive care unit (NICU) admissions were evaluated and reported. RESULTS: Overall 308 patients were enrolled in the study. Smoker mothers had significantly smaller placentas (P-value = .008), and those with lower diameter placentas were more likely to suffer from IUFD (P-value = .0001). Shorter placental cord insertion distances led to more episodes of preterm labor (P-value = .057). Eccentric-type placental cord insertion was significantly associated with the development of preeclampsia (P-value = .006). DISCUSSION: Abnormalities in placental diameter and cord insertion can lead to significant maternal-fetal complications including preterm labor, IUFD, and preeclampsia.

OBJECTIVES: The benefits of sildenafil by increasing blood flow in the improvement of Doppler parameters of umbilical (UA), uterine (UtA), and fetal middle cerebral arteries (MCA) remain uncertain. On the other hand, insufficient blood flow during uterine contractions in labor can lead to decrease blood supply and fetal distress. Therefore, we aimed to assess the changes in fetal Doppler indices and maternal and neonatal outcomes following the use of sildenafil in the active phase of labor in low-risk pregnancies with healthy fetuses. METHODS: This randomized double-blinded controlled trial was conducted on 70 pregnant single low-risk, pregnant women. The patients were randomly assigned into two groups receiving sildenafil (n=35) or placebo (n=35) when the active phase of labor was initiated. Doppler parameters were assessed at baseline as well as 3â¯h after that. Indeed, the maternal and neonatal outcomes were compared between groups. RESULTS: The Doppler parameters including the pulsatility index of MCA, UA, and left and right UtA remained unchanged after the administration of sildenafil. Neonatal outcomes including birth weight, PH of the umbilical artery, Apgar score, respiratory distress syndrome, and neonatal intensive care unit admission as well as maternal outcomes such as cesarean section rate and the occurrence of intrapartum/postpartum hemorrhage had no difference between groups. CONCLUSIONS: The use of sildenafil in the active phase of labor in low-risk pregnancies may not be beneficial in improving Doppler parameters in MCA, umbilical, and uterine arteries and thus may not improve pregnancy outcomes.

BACKGROUND: Given the limited availability of research on the association between COVID-19 infection and breastfeeding success, the primary objective of this study is to conduct a comprehensive evaluation of this relationship. METHODS: This prospective cohort study included 260 women who were on the postnatal ward of an academic hospital affiliated with Tehran University of Medical Sciences during the COVID-19 pandemic (between March and August 2021). Among these women, 130 had tested positive for COVID-19 in pregnancy, while the remaining 130 were considered healthy. The study aimed to assess various factors, including sociodemographic characteristics and the results of four validated questionnaires: The Bristol Breastfeeding Questionnaire, The Multidimensional of Perceived Social Support (MPSS), The Breastfeeding Self-Efficacy Scale (BSES), and The Postpartum Partner Support Scale (PPSS). These questionnaires were administered to each participant to gather relevant data. After eight weeks, a telephone follow-up was carried out to assess the success of breastfeeding. The evaluation focused on determining if exclusive breastfeeding was maintained or not. Data was collected by questioning mothers about their infants' feeding habits in the past 24 h. Exclusive breastfeeding refers to the exclusive use of breast milk without the introduction of other liquids or solid foods. RESULTS: Women with a previous COVID-19 infection (case group) had a lower mean infant gestational age (P < 0.001) and a higher prevalence of cesarean section (P = 0.001) compared to the control group. The proportion of women who exclusively breastfed was higher in the control group (98.5%) than in women with a history of COVID-19 infection (89.2%) (P = 0.011). Furthermore, the case group reported lower scores in perceived social support and the Breastfeeding Self-Efficacy Scale, in contrast to the control group. Notably, there was a significant correlation between breastfeeding success and women's breastfeeding self-efficacy score. CONCLUSIONS: The findings of this study offer valuable insights for healthcare professionals, enabling them to promote early initiation of breastfeeding in mothers with a history of COVID-19 infection, while ensuring necessary precautions are taken.
