RESUMO
Cesarean delivery rates have been steadily rising since the beginning of the 21st century. The growing incidence is even more prominent in developing countries owing to lack of evidence-based guidance and audit, and the expansion of private practice. The uprise in Cesarean delivery rate has been associated with considerable financial burden and has increased the risk otherwise uncommon serious complications such as placenta accreta disorders and uterine rupture. In addition to primary prevention of Cesarean delivery, trial of labor after cesarean section is one of the most successful strategies to reduce Cesarean deliveries and minimize risks associated with higher order Cesarean deliveries. This guideline appraises patient selection strategies and use of prediction model to promote counseling and enhance safety in women considering vaginal birth after Cesarean.

OBJECTIVE: To establish a prognostic model for endometrial cancer (EC) that individualizes a risk and management plan per patient and disease characteristics. METHODS: A multicenter retrospective study conducted in nine European gynecologic cancer centers. Women with confirmed EC between January 2008 to December 2015 were included. Demographics, disease characteristics, management, and follow-up information were collected. Cancer-specific survival (CSS) and disease-free survival (DFS) at 3 and 5 years comprise the primary outcomes of the study. Machine learning algorithms were applied to patient and disease characteristics. Model I: pretreatment model. Calculated probability was added to management variables (model II: treatment model), and the second calculated probability was added to perioperative and postoperative variables (model III). RESULTS: Of 1150 women, 1144 were eligible for 3-year survival analysis and 860 for 5-year survival analysis. Model I, II, and III accuracies of prediction of 5-year CSS were 84.88%/85.47% (in train and test sets), 85.47%/84.88%, and 87.35%/86.05%, respectively. Model I predicted 3-year CSS at an accuracy of 91.34%/87.02%. Accuracies of models I, II, and III in predicting 5-year DFS were 74.63%/76.72%, 77.03%/76.72%, and 80.61%/77.78%, respectively. CONCLUSION: The Endometrial Cancer Individualized Scoring System (ECISS) is a novel machine learning tool assessing patient-specific survival probability with high accuracy.

INTRODUCTION: Since Friedman's seminal publication on laboring women, numerous publications have sought to define normal labor progress. However, there is paucity of data on contemporary labor cervicometry incorporating both maternal and neonatal outcomes. The objective of this study is to establish intrapartum prediction models of unfavorable labor outcomes using machine-learning algorithms. MATERIALS AND METHODS: Consortium on Safe Labor is a large database consisting of pregnancy and labor characteristics from 12 medical centers in the United States. Outcomes, including maternal and neonatal outcomes, were retrospectively collected. We defined primary outcome as the composite of following unfavorable outcomes: cesarean delivery in active labor, postpartum hemorrhage, intra-amniotic infection, shoulder dystocia, neonatal morbidity, and mortality. Clinical and obstetric parameters at admission and during labor progression were used to build machine-learning risk-prediction models based on the gradient boosting algorithm. RESULTS: Of 228,438 delivery episodes, 66,586 were eligible for this study. Mean maternal age was 26.95 ± 6.48 years, mean parity was 0.92 ± 1.23, and mean gestational age was 39.35 ± 1.13 weeks. Unfavorable labor outcome was reported in 14,439 (21.68%) deliveries. Starting at a cervical dilation of 4 cm, the area under receiver operating characteristics curve (AUC) of prediction models increased from 0.75 (95% confidence interval, 0.75-0.75) to 0.89 (95% confidence interval, 0.89-0.90) at a dilation of 10 cm. Baseline labor risk score was above 35% in patients with unfavorable outcomes compared to women with favorable outcomes, whose score was below 25%. CONCLUSION: Labor risk score is a machine-learning-based score that provides individualized and dynamic alternatives to conventional labor charts. It predicts composite of adverse birth, maternal, and neonatal outcomes as labor progresses. Therefore, it can be deployed in clinical practice to monitor labor progress in real time and support clinical decisions.

INTRODUCTION: Endometrial hyperplasia is associated with varying risk of endometrial cancer. The aim of this review is to assess effectiveness of levonorgestrel-releasing intrauterine system (LNG-IUS), compared to systemic progestins, in management of endometrial hyperplasia MATERIALS AND METHODS: A search on studies comparing LNG-IUS to systemic progestins was conducted on Scopus, Web of science, Cochrane, PubMed and Embase databases, from the date of inception to September 20th, 2020. Studies were excluded if they were non-comparative, animal studies, review articles, case reports, case series, and conference papers. Primary outcomes include resolution/regression rate, failure rate, and hysterectomy rate. Analysis was pooled using random effect model and was expressed as pooled odds ratios (OR) and 95% confidence interval (CI). Quality assessment was performed using Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale (NOS) assessment tool. MOGGE Meta-analysis Matrix was used to illustrate multiple subgroup analyses. RESULTS: Out of 341 studies retrieved from literature search, 12 were eligible. LNG-IUS yielded significantly higher resolution/regression rate (91.3% vs 68.6%, OR 3.42, 95% CI 1.86-6.30). Failure and hysterectomy rates were significantly lower in LNG-IUS group compared to systemic progestins' group (19.2% vs. 32.3%, OR 0.34, 95% CI 0.20-0.57 and 9.3% vs. 24.1%, OR 0.41, 95% CI 0.29-0.57, respectively). Subgroup analysis of studies including complex hyperplasia only did not show significant difference in resolution/regression rate was not statistically significant. CONCLUSION: LNG-IUS is associated with high success rate in management of women with endometrial hyperplasia. However, specific effectiveness of LNG-IUS on more advanced histologic subtypes is less studied.

In the digital age of the 21st century, we have witnessed an explosion in data matched by remarkable progress in the field of computer science and engineering, with the development of powerful and portable artificial intelligence-powered technologies. At the same time, global connectivity powered by mobile technology has led to an increasing number of connected users and connected devices. In just the past 5 years, the convergence of these technologies in obstetrics and gynecology has resulted in the development of innovative artificial intelligence-powered digital health devices that allow easy and accurate patient risk stratification for an array of conditions spanning early pregnancy, labor and delivery, and care of the newborn. Yet, breakthroughs in artificial intelligence and other new and emerging technologies currently have a slow adoption rate in medicine, despite the availability of large data sets that include individual electronic health records spanning years of care, genomics, and the microbiome. As a result, patient interactions with health care remain burdened by antiquated processes that are inefficient and inconvenient. A few health care institutions have recognized these gaps and, with an influx of venture capital investments, are now making in-roads in medical practice with digital products driven by artificial intelligence algorithms. In this article, we trace the history, applications, and ethical challenges of the artificial intelligence that will be at the forefront of digitally transforming obstetrics and gynecology and medical practice in general.

Since the 50 s of the last century, labor charts have been proposed and appraised as a tool to diagnose labor abnormalities and guide decision-making. The partogram, the most widely adopted form of labor charts, has been endorsed by the world health organization (WHO) since 1994. Nevertheless, recent studies and systematic reviews did not support clinical significance of application of the WHO partogram. These results have led to further studies that investigate modifications to the structure of the partogram, or more recently, to reconstruct new labor charts to improve their clinical efficacy. This guideline appraises current evidence on use of labor charts in management of labor specially in low-resource settings.

OBJECTIVE: To validate the use of placenta accreta risk-antepartum (PAR-A) score as a predictive tool of clinical outcomes of placenta accreta spectrum (PAS). METHODS: This is a prospective study, conducted in six PAS specialized centers in six different countries. The study was conducted between October 1, 2020 and March 31, 2021. Women who were provisionally diagnosed with PAS during pregnancy were considered eligible. A machine-learning-based PAR-A score was calculated. Diagnostic performance of the PAR-A score was evaluated using a receiver operating characteristic curve, for perioperative massive blood loss and admission to intensive care unit (ClinicalTrials.gov identifier NCT04525001). RESULTS: Of 97 eligible women, 86 were included. PAS-associated massive blood loss occurred in 10 patients (11.63%). Median PAR-A scores of massive blood loss in the current cohort were 8.9 (interquartile range 6.9-14.1). In predicting massive blood loss, the area under the curve of PAR-A scores was 0.85 (95% confidence interval [CI] 0.74-0.95), which was not significantly different from the original cohort (P = 0.2). PAR-A score prediction of intensive care unit admission was slightly higher compared with the original cohort (0.88, 95% CI 0.81-0.95; P = 0.06). CONCLUSION: PAR-A score is a novel scoring system of PAS outcomes, which showed external validity based on current data.

INTRODUCTION: Placenta accreta spectrum is a major obstetric disorder that is associated with significant morbidity and mortality. The objective of this study is to establish a prediction model of clinical outcomes in these women. MATERIALS AND METHODS: PAS-ID is an international multicenter study that comprises 11 centers from 9 countries. Women who were diagnosed with PAS and were managed in the recruiting centers between 1 January 2010 and 31 December 2019 were included. Data were reanalyzed using machine learning (ML) models, and 2 models were created to predict outcomes using antepartum and perioperative features. ML model was conducted using python® programing language. The primary outcome was massive PAS-associated perioperative blood loss (intraoperative blood loss ≥2500 ml, triggering massive transfusion protocol, or complicated by disseminated intravascular coagulopathy). Other outcomes include prolonged hospitalization >7 days and admission to the intensive care unit (ICU). RESULTS: 727 women with PAS were included. The area under curve (AUC) for ML antepartum prediction model was 0.84, 0.81, and 0.82 for massive blood loss, prolonged hospitalization, and admission to ICU, respectively. Significant contributors to this model were parity, placental site, method of diagnosis, and antepartum hemoglobin. Combining baseline and perioperative variables, the ML model performed at 0.86, 0.90, and 0.86 for study outcomes, respectively. Ethnicity, pelvic invasion, and uterine incision were the most predictive factors in this model. DISCUSSION: ML models can be used to calculate the individualized risk of morbidity in women with PAS. Model-based risk assessment facilitates a priori delineation of management.

OBJECTIVE: To compare the effectiveness and outcomes of interventional resealing of membranes, "amniopatch" for spontaneous vs. iatrogenic preterm premature rupture of the membranes (sPPROM and iPPROM). METHODS: We performed a systematic review of literature involving an electronic search of the following databases: Ovid MEDLINE(R) and Epub Ahead of Print, In-Process and Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, and Scopus. An indirect meta-analysis was then performed to compare the obstetric, maternal, fetal, and neonatal outcomes of amniopatch between the sPPROM and iPPROM groups. RESULTS: The mean gestational age (GA) at the time rupture was 17.8 ± 1.8 and 25.2 ± 3.8 weeks for iPPROM and sPPROM, respectively, p = .005. Mean GA at the time of amniopatch procedure was 19.2 ± 2.07 weeks for iPPROM and 23 ± 3.1 weeks of gestation for sPPROM, p = .023. The rates of fluid re-accumulation (sPPROM 26% and iPPROM 53%, p = .09) were comparable between the sPPROM and iPPROM groups. Neonatal outcomes except for the rate of IUFD were also comparable between the groups. The incidence of IUFD was significantly higher in the iPPROM group (ES: 24%; 95% CI: 8.00-44.0%; p < .001), compared to sPPROM (ES: 0%; 95% CI: 0.00-4.00%). Obstetric and maternal outcomes were comparable between the two groups. CONCLUSIONS: Amniopatch appears to be a feasible and safe procedure for PPROM treatment. Further research is warranted to investigate the effectiveness of this procedure and establish a standardized criterion for the appropriate selection of patients that could benefit from this intervention.

Rectovaginal colonization with group B streptococcus (GBS) is commonly encountered in pregnancy. GBS is the most common cause of early onset neonatal sepsis, which is associated with 12% case-fatality rate. Although screening protocols and prophylactic treatment are readily available worldwide, practice in low-resource countries is challenged by lack of awareness and limited implementation of these protocols. In addition, antibiotic susceptibility pattern may vary globally owing to different regulations of antibiotic prescription or prevalence of certain bacterial serotypes. This guideline appraises current evidence on screening and management of GBS colonization in pregnancy particularly in low-resource settings.

OBJECTIVE: To appraise clinical outcomes of systematic lymphadenectomy in women with ovarian cancer based on stage, control group and type of chemotherapy. STUDY DESIGN: A literature search was conducted on SCOPUS, PUBMED, COCHRANE, MEDLINE, and WEB OF SCIENCE databases. All comparative studies that assess outcomes of systematic lymphadenectomy in patients with ovarian cancer were eligible. Overall survival was analyzed by pooling log hazard ratio (HR) and standard error of multivariable Cox regression models. MOGGE Meta-analysis Matrix is a novel illustration tool that was used to demonstrate multiple subgroup analyses of included studies. RESULTS: Twenty-two studies were eligible. Systematic lymphadenectomy was associated with better overall survival, that was close to significance, compared to control group (HR 0.93, 95 %CI 0.86-1.00). Among women treated with adjuvant chemotherapy, overall survival improved in women with stage IIB-IV who underwent systematic lymphadenectomy (HR 0.91, 95 %CI 0.84-0.99) and was most significant among patients with stage III to IV (HR 0.85, 95 %CI 0.73-0.99). Systematic lymphadenectomy did not improve survival in women who received neoadjuvant chemotherapy (HR 0.97, 95 %CI 0.73-1.29). Systematic lymphadenectomy was associated with improved progress-free survival compared to control group (HR 0.88, 95 %CI 0.79-0.99). CONCLUSION: Although data from clinical trials do not support role of systematic lymphadenectomy in advanced ovarian cancer, overall data conveys stage-specific survival benefit. Further clinical trials may be warranted to assess substage survival outcomes in women with advanced stages.

AIM: To evaluate perinatal outcomes of incidental septostomy (IS) after laser photocoagulation for twin-to-twin transfusion syndrome (TTTS), and to compare the outcomes with those who had intact intertwin membrane. METHODS: Databases such as PubMed, Web of Science, Scopus, and Embase were systematically searched from inception up to August 2020. The random-effects model was used to pool the mean difference (MD) or odds-ratio (OR) with the corresponding 95% confidence intervals (CIs). Primary outcome was incidence of preterm delivery, and preterm premature rupture of membranes (PPROM), while secondary outcomes included gestational age (GA) at intervention, GA at delivery, neonatal survival, and incidence of pseudoamniotic band syndrome (PABS). RESULTS: Four studies (1442 patients) met our inclusion criteria. Postoperative identification of IS was associated with earlier GA at delivery (MD = -2.52; 95% CI: -3.22, -1.82; p < 0.00), higher risk of PPROM < 32 weeks (OR = 2.82; 95% CI: 1.80, 4.40; p < 0.001), and preterm delivery < 32 weeks (OR = 4.01; 95% CI: 1.27, 12.63; p = 0.02). No differences were noted in pseudoamniotic band syndrome, at least one or dual neonatal survival rate between IS and non-IS groups. CONCLUSIONS: Occurrence of IS after laser photocoagulation for TTTS is associated with earlier GA at delivery, increased risk for PPROM and preterm delivery <32 weeks' gestation. However, neonatal survival does not appear to be affected by this complication.

Monitoring the uterine contraction during pregnancy is necessary to monitor labor progress, fetal and maternal well-being, and uterine activity. The aim of this review was to evaluate the performance of electrohysterography and to analyze the nature of uterine contraction. A search was undertaken using PubMed, Embase, and ClinicalTrials.gov database from 1 January 1950 to 1 November 2018. Search terms include: "Uterine" or "Uterus" or "Labor" or "Labour" and "electrical activity" or "electrohysterogram" or "electrohysterograph". Reviewing the literature, electrohysterography showed a higher sensitivity for uterine contraction detection and was independent of body mass index, abdominal wall thickness, or maternal position enabling monitoring obese patients as well. Electrohysterography can enhance uterine monitoring throughout labor because of its noninvasiveness, adhesive properties, and reduced obesity sensitiveness. Electrohysterography should be available to safely improve intrapartum monitoring instead of the invasive intrauterine pressure catheter.

OBJECTIVE: To create a model for prediction of success of uterine-preserving procedures in women with placenta accreta spectrum (PAS). METHODS: PAS-ID is a multicenter study that included 11 centers from 9 countries. Women with PAS, who were managed between January 1, 2010 and December 31, 2019, were retrospectively included. Data were split into model development and validation cohorts, and a prediction model was created using logistic regression. Main outcome was success of uterine preservation. RESULTS: Out of 797 women with PAS, 587 were eligible. Uterus-preserving procedures were successful in 469 patients (79.9%). Number of previous cesarean sections (CS) was inversely associated with management success (adjusted odds ratio [aOR] 0.02, 95% confidence interval [CI] 0.001-3.63 with five previous CS). Other variables were complete placental invasion (aOR 0.14, 95% CI 0.05-0.43), type of CS incision (aOR 0.04, 95% CI 0.01-0.25 for classical incision), compression sutures (aOR 2.48, 95% CI 1.00-6.16), accreta type (aOR 3.76, 95% CI 1.13-12.53), incising away from placenta (aOR 5.09, 95% CI 1.52-16.97), and uterine resection (aOR 102.57, 95% CI 3.97-2652.74). CONCLUSION: The present study provides a prediction model for success of uterine preservation, which may assist preoperative and intraoperative decisions, and promote incorporation of uterine preservation procedures in comprehensive PAS protocols.

BACKGROUND: High-intensity focused ultrasound (HIFU) is a non-invasive procedure that has been studied in the management of placenta accreta spectrum (PAS). OBJECTIVE: To appraise HIFU in the management of PAS and highlight the restrictions on converting uterus-preserving studies into evidence-based practice. SEARCH STRATEGY: A search on Scopus, Cochrane, PubMed and Web of Science was conducted from date of inception to January 2020. SELECTION CRITERIA: Studies on using HIFU in the management of PAS were eligible. Review articles, conference papers, and case reports were excluded. DATA COLLECTION: A standardized sheet was used to abstract data from eligible studies. CON-PAS registry was used to include studies on other conservative modalities. RESULTS: Four studies were eligible (399 patients). Average residual placental volume was 61.74 cm3 (6.01-339 cm3 ). Treatment was successful in all patients. Normal menstruation recovered after 48.8 days (15-150 days). No major complications were encountered. Sixty-one studies were retrieved from the CON-PAS registry; uterine artery embolization (23 studies), balloon placement (15 studies), compression sutures (10 studies), placenta in situ (7 studies), and uterine resection (6 studies) were successful in 83.7%, 92.9%, 87.9%, 85.2%, and 79.3% of cases, respectively. CONCLUSIONS: HIFU may fit certain clinical situations in the management of PAS. A global research strategy is recommended to incorporate conservative approaches within a comprehensive management protocol.

Besides histologic features, the presence of nodal metastasis is the most crucial prognostic factor for recurrence and survival for patients with gynecologic cancer. Conventionally, lymphadenectomy has been performed routinely to assess lymphatic metastasis. However, lymphadenectomy may be unnecessary in early-stage gynecologic cancer, because the percentage of patients with lymph node involvement is very low. The recent use of sentinel lymph node mapping has provided high feasibility, safety, and accuracy in the assessment of nodal metastasis. The National Comprehensive Cancer Network Clinical Practice Guidelines have incorporated the sentinel lymph node for nodal evaluation in vulvar, endometrial, and cervical cancers.

OBJECTIVE: To evaluate outcomes of fluorinated corticosteroids, with or without other medications, for treatment of congenital heart block in-utero. STUDY DESIGN: A search was conducted through MEDLINE, EMBASE, WEB OF SCIENCE and SCOPUS from inception to October 2017. Only comparative studies are considered eligible. Outcomes include fetal death, downgrade of heart block, neonatal death, need for neonatal pacing, fetal and maternal complications. Random effects model was used. RESULTS: Out of 923 articles, 12 studies were eligible. Compared to no treatment, there was no significant difference in incidence of fetal death (OR 1.10, 95%CI 0.65-1.84), neonatal death (OR 0.98, 95%CI 0.41-2.33), or need for pacing (OR 1.46, 95%CI 0.78-2.74). Heart block downgrade was significantly higher in treatment group (9.48%vs.1.76%, OR 3.27, 95%CI 1.23-8.71). CONCLUSION: antenatal fluorinated corticosteroids do not improve fetal/neonatal morbidity or mortality of congenital heart block and are associated with higher incidence of fetal and maternal complications.
RESUMO
OBJECTIVE: The objective of the study was to describe the characteristics and outcomes of patients with antenatal diagnosis of vasa previa and evaluate the predictive factors of resolution in a contemporary large, multicenter data set. STUDY DESIGN: This was a retrospective multicenter cohort study of all antenatally diagnosed cases of vasa previa, identified via ultrasound and electronic medical record, between January 2011 and July 2018 in 5 US centers. Records were abstracted to obtain variables at diagnosis, throughout pregnancy, and outcomes, including maternal and neonatal variables. Data were reported as median [range] or n (percentage). Descriptive statistics, receiver-operating characteristics, and logistic regression analysis were used as appropriate. RESULTS: One hundred thirty-six cases of vasa previa were identified in 5 centers during the study period, 19 (14%) of which resolved spontaneously at median estimated gestational age of 27 weeks [19-34]. All subjects with unresolved vasa previa underwent cesarean delivery at a median estimated gestational age of 34 weeks [27-39] with the median estimated blood loss of 800 mL [250-2000]. Rates for vaginal bleeding, preterm labor, premature rupture of membrane, and need for blood product transfusion were not different between the resolved and unresolved group (P = NS). The odds ratio for resolution in those with the estimated gestational age of less than 24 weeks at the time of diagnosis was 7.9 (95% confidence interval, 2.1-29.4) after adjustment for confounding variables. CONCLUSION: Our data suggest that outcomes in antenatally diagnosed cases of vasa previa are excellent. Furthermore, our data report a higher chance of resolution when the condition is diagnosed before 24 weeks of gestation.

BACKGROUND: Vaginal agenesis is a müllerian anomaly characterized by congenital absence of the vagina. In this case series, the authors describe a novel, minimally invasive technique using microport entry for treatment of complete vaginal agenesis. TECHNIQUE: A balloon catheter is passed through a fenestrated perfluoroalkoxy polymer resin-supporting platform, then tied by a silk suture over the caudal end of the inserter. Two 4-mm microports are created intraumbilically; one to insert the scope and the other to introduce the catheter inserter that is advanced under direct vision. The inserter loaded with a catheter is passed across the pelvic floor to position the balloon at the vaginal dimple. The balloon is inflated and tightly positioned against the dimple. The perfluoroalkoxy polymer resin piece is clamped at the umbilicus. Traction is applied to the catheter stem and increased progressively to achieve desired vaginal depth. EXPERIENCE: Twenty-two women aged 17-28 years with vaginal agenesis underwent microport vaginoplasty. Twenty-one women were diagnosed with müllerian agenesis and one patient with androgen insensitivity syndrome. Preoperative vaginal depth ranged between 0.5 and 3 cm. The procedure was well tolerated with no intraoperative or postoperative complications. Patients achieved neovaginal depth between 9 and 11 cm and penetrations scores increased to 80-90%. CONCLUSION: Microport vaginoplasty is a feasible and effective procedure for management of vaginal agenesis.
