Effect of type III female genital mutilation on obstetric outcomes: A systematic review and meta-analysis. Heliyon 2024; 10:e29336. [PMID: 38628703 PMCID: PMC11019231 DOI: 10.1016/j.heliyon.2024.e29336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 04/05/2024] [Accepted: 04/05/2024] [Indexed: 04/19/2024] Open
Abstract
Background Controversial evidence suggests a potential association between female genital mutilation (FGM/C) and adverse obstetric outcomes, with type III FGM/C (infibulation) carrying the greatest risk. The aim of this systematic review and meta-analysis was to assess current rate of adverse obstetric outcomes in women with type III female genital mutilation and cutting (FGM/C; infibulation) delivering across different settings worldwide. Methods We searched PubMed, Scopus, Embase, and ClinicalTrials.gov databases from inception to Jan 1, 2023. Studies were selected if they included the main outcome of postpartum haemorrhage (PPH) or secondary outcomes, which included major conditions affecting maternal-neonatal health during labour and delivery. DerSimonian-Laird random effects meta-analysis including pooled effect estimates with corresponding 95 % confidence intervals was performed. Heterogeneity was assessed using the I2 statistic. Meta regression for relevant covariates was performed when data on relevant confounders were available. The Newcastle-Ottawa scale (NOS) was used to assess quality of observational studies. The level of evidence was assessed with the GRADE method. Results 14 observational studies including 15,320 type III FGM/C women and 59,347 controls were eligible. The risk for postpartum haemorrhage was significantly increased in type III FGM/C, in the main analysis (OR 1.83, 95 % CI 1.03 to 3.24, I2 = 93 %), in pooling of data adjusted for confounders (aOR 1.76, CI 1.42 to 2.17, I2 = 0 %), and in sensitivity analysis of higher quality studies with NOS≥7 (OR 2.76, CI 1.38 to 5.51, I2 = 95 %). Meta-regression showed that nulliparity was significantly and positively associated with postpartum haemorrhage. Similarly, analysis of data adjusted for confounders showed an increased risk of episiotomy in type III FGM/C (aOR 1.56, CI 1.03 to 2.35, I2 = 52 %). Sensitivity analysis of studies with NOS≥7 revealed a significant increase for episiotomy (OR 7.53, CI 1.19 to 47.54, I2 = 96 %), perineal tears (OR 4.24, CI 1.09 to 16.46, I2 = 66 %), prolonged second stage of labour (OR 5.19, 95 % CI 1.00 to 26.85, I2 = 66 %), and Apgar score less than 7 (OR 4.19, CI 1.64 to 10.70, I2 = 0 %). No difference was found regarding obstetric anal sphincter injuries and mode of delivery in these women. Deinfibulation achieved similar obstetric and neonatal outcomes to women who never had type III FGM. The overall quality of the studies was adequate (median NOS score: 7; IQR: 6-8), the level of evidence, according to the GRADE assessment, was low. Conclusions These results consistently show an increased risk of adverse obstetric outcomes in women with FGM/C type III. Infibulation substantially increases the risk for PPH, particularly in nulliparae. Systematic Review registration: PROSPERO CRD42023421993.

Does maternal oxygen administration during non-reassuring fetal status affect the umbilical artery gas measures and neonatal outcomes? Arch Gynecol Obstet 2024; 309:993-1000. [PMID: 36854985 PMCID: PMC9974390 DOI: 10.1007/s00404-023-06952-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 01/26/2023] [Indexed: 03/02/2023]
Abstract
PURPOSE To clarify whether maternal oxygen administration during vaginal delivery improves umbilical artery (UA) gas measurements and neonatal outcomes. METHODS Singleton pregnancies requiring operative vaginal delivery or emergency cesarean section (CS) due to non-reassuring fetal status (NRFS) during vaginal delivery at our hospital from 2018 to 2021 were retrospectively investigated. Intrapartum fetal wellbeing was evaluated based on the 5-tier fetal heart rate (FHR) pattern which is a delivery management method widely used in Japan. Operative vaginal deliveries or emergency CS was performed under integrated judgment in NRFS. Patients were divided into the oxygen group to whom oxygen (10 L/min) was supplied by a facemask and the room air group. The UA gas measurements and neonatal outcomes were compared. The oxygen administration was classified by conditions before and after the coronavirus disease 2019 pandemic. As a secondary evaluation, stratification of FHR pattern levels and factors associated with UA pH < 7.15 were examined. RESULTS A total of 250 patients required obstetric surgical delivery due to NRFS, including 140 (56%) and 110 (44%) in the oxygen and room air groups, respectively. No differences in maternal background factors were found between both groups, except for maternal age. UA gas measurements and neonatal outcomes also showed no significant differences. No significant factors were extracted in the multivariate analysis for UA pH < 7.15. CONCLUSIONS Trans-maternal oxygen administration for intrapartum NRFS did not affect neonatal cord blood gasses or neonatal outcomes. Thus, routine oxygen administration for intrapartum NRFS may not always be necessary.

Damhuis SE, Groen H, Thilaganathan B, Ganzevoort W, Gordijn SJ. Effect of intrapartum epidural analgesia on rate of emergency delivery for presumed fetal compromise: nationwide registry-based cohort study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 62:668-674. [PMID: 37448203 DOI: 10.1002/uog.26309] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 07/15/2023]
Abstract
OBJECTIVES To determine the rate of emergency delivery for presumed fetal compromise after epidural analgesia (EDA) compared with that after alternative analgesia or no analgesia, and to assess whether this rate is increased in pregnancies with reduced placental reserve. METHODS This was a nationwide registry-based cohort study of 629 951 singleton pregnancies delivered at 36 + 0 to 42 + 0 weeks of gestation that were recorded in the Dutch national birth registry between 2014 and 2018, including 120 426 cases that received EDA, 86 957 that received alternative analgesia and 422 568 that received no analgesia during labor. Pregnancies with congenital anomaly, chromosomal abnormality, fetal demise, planned Cesarean delivery, non-cephalic presentation at delivery and use of multiple forms of analgesia were excluded. The primary outcome was emergency delivery for presumed fetal compromise. Secondary outcomes included delivery characteristics and neonatal outcome. Negative binomial regression analysis was stratified by parity and results are presented according to birth-weight centile, after adjusting for confounding. RESULTS Among women who received EDA, 13.2% underwent emergency delivery for presumed fetal compromise, compared with 4.1% of women who had no analgesia (relative risk (RR), 3.23 (95% CI, 3.16-3.31)) and 7.0% of women who received alternative analgesia (RR, 1.72 (95% CI, 1.67-1.77)). Independent of birth weight, the RR of presumed fetal compromise after EDA vs no analgesia was higher in parous women (adjusted RR (aRR), 2.15 (95% CI, 2.04-2.27)) compared with nulliparous women (RR, 1.88 (95% CI, 1.84-1.94)). Stratified for parity, the effect of EDA was modified significantly by birth-weight centile (interaction P-value, < 0.001 for nulliparous and 0.004 for parous women). The emergency delivery rate following EDA was highest in those with a birth weight < 5th centile (25.2% of nulliparous and 16.6% of parous women), falling with each increasing birth-weight centile category up to the 91st -95th centile (11.8% of nulliparous and 7.2% of parous women). CONCLUSIONS Intrapartum EDA is associated with a higher risk of emergency delivery for presumed fetal compromise compared with no analgesia and alternative analgesia, after adjusting for relevant confounding. The highest rate of emergency delivery for presumed fetal compromise was observed at the lowest birth-weight centiles. RRs of emergency delivery for presumed fetal compromise after EDA were modestly but consistently modified by birth-weight centile, supporting the hypothesis that the adverse effects of EDA are exacerbated by reduced placental function. While EDA provides effective pain relief during labor, alternative strategies for pain management may be preferable in pregnancies with a high background risk of fetal compromise. © 2023 The Authors.

Diagnostic accuracy of pre-induction cervical elastography, volume, length, and uterocervical angle for the prediction of successful induction of labor with dinoprostone. Arch Gynecol Obstet 2023; 308:1301-1311. [PMID: 37210702 DOI: 10.1007/s00404-023-07076-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 05/08/2023] [Indexed: 05/22/2023]
Abstract
PURPOSE The study's aim is to define among a group of ultrasonographic cervical measurements a candidate parameter predictive of successful of induction of labor in term pregnancies with unfavorable cervix. METHODS This prospective observational study included 141 pregnant women at term with an unfavorable cervix (Bishop score ≤ 6). All patients underwent clinical and ultrasonographic cervical evaluation before dinoprostone induction. Pre-induction cervical assessments included the Bishop score, cervical length, cervical volume, uterocervical angle, and cervical elastographic parameters. Vaginal delivery (VD) was accepted as successful dinoprostone induction. Multivariate logistic regression was conducted to identify the potential risk factors significantly associated with CS while controlling for possible confounding variables. RESULTS The vaginal delivery rate was 74% (n = 93) and the cesarean section (CS) rate was 26% (n = 32). Sixteen patients who had a cesarean section due to fetal distress before the active phase of labor were excluded from the study. The mean induction-to-delivery interval was 1176.1 ± 352 (540-2150) for VD and 1359.4 ± 318.4 (780-2020) for CS (p = 0.01). Bishop score was lower in women with cesarean section (p = 0.002). When both groups were compared in terms of delivery type, no difference was found between cervical elastography values, cervical volume, cervical length, and uterocervical angle measurements. Multivariable logistic regression model failed to show significant differences between cervical elastography values, cervical volume, cervical length, and uterocervical angle measurements. CONCLUSION Cervical length, cervical elastography, cervical volume, and uterocervical angle measurements did not provide a clinically useful prediction of outcomes following labor induction in our study group with unfavorable cervix. Cervical length measurements significantly predicted the time interval from induction to delivery.

Abstract
PURPOSE An emergency caesarean section (CS) has more complications than a planned CS. The arrest of labour is a major indication for an emergency CS. This study aimed to develop a prediction model for the arrest of labour to be used in regular check-ups at 36 or 37 gestational weeks for primiparas. METHODS This was a retrospective cohort study conducted at a single institution in Japan using data from January 2007 to December 2013. Primiparas attending regular check-ups during 36 or 37 gestational weeks, with live single foetuses in a cephalic presentation were included. The outcome was the incidence of labour arrest. Candidate predictors included 25 maternal and foetal findings. We developed a prediction model using logistic regression analysis with stepwise selection. A score was assigned to each predictor of the final model based on their respective β coefficients. RESULTS A total of 739 women were included in the analysis. Arrest of labour was diagnosed in 47 women (6.4%), and all of them delivered by emergency CS. The predictors in the final model were a Bishop score ≤ 1, maternal height ≤ 154 cm, foetal biparietal diameter ≥ 91 mm, pre-pregnancy weight ≥ 54 kg, maternal haemoglobin concentration ≥ 11.0 g/dl, and amniotic fluid index ≥ 13. The area under the receiver operating characteristic curve was 0.783. CONCLUSION We have developed the first model to predict arrested labour before its onset. Although this model requires validation using external samples, it will help clinicians and pregnant women to control gestational conditions and make decisions regarding planned CS.

Abstract
PURPOSE The aim of the study was to determine the cause-specific hazard (CSH) and the cumulative incidence function (CIF) for umbilical cord metabolic acidemia at birth (MA; pH < 7.0 and/or BE [Formula: see text] - 12 mmol/L) at delivery in patients experiencing the 2nd stage of labor (2STG), stratified for both FIGO-2015 pathologic intrapartum cardiotocography requiring expedited delivery (CTG_RED) and duration of 2nd stage of labor. METHODS 3459 pregnancies experiencing the 2nd stage of labor and delivering at the Division of Obstetrics and Prenatal Medicine, IRCCS Sant'Orsola-Malpighi Hospital, Bologna (Italy), were identified between 2018 and 2019. Survival analysis was used to assess CSH and CIF for MA, stratified for FIGO-2015 pathologic CTG and relevant covariates. RESULTS FIGO-2015 pathological CTG with expedited operative delivery or urgent cesarean section within 10 or 20 min from diagnosis, respectively occurred in 282/3459 (8.20%). The rate of MA at delivery was 3.32% (115/3459). The spline of CSH for MA showed a direct correlation with the duration of 2STG always presenting higher values and greater slope in the presence of pathologic CTG, with plateau between 60 and 120 min and rapid increase after 120 min. The CIF at 180 min in the 2STG was 2.67% for nonpathological and 10.63% for pathological CTG_RED. Nulliparity, pathological CTG, and meconium-stained amniotic fluid resulted significant predictors of MA in our multivariable model. CONCLUSION The risk for MA increases moderately across the 2STG with nonpathological CTG and quadruples with pathological CTG_RED. Adjustment for other predictors of MA including meconium-stained amniotic fluid and nulliparity reveals a significant hazard increase for MA associated with pathologic CTG_RED.

Abstract
OBJECTIVE The aim of this study was to evaluate the accuracy of intrapartum cardiotocography in identifying fetal acidemia by umbilical cord blood analysis in low-risk pregnancies. METHODS This is a retrospective cohort study of low-risk singleton pregnancies in labor after performing intrapartum cardiotocography categories I, II, and III. The presence of fetal acidemia at birth was identified by analyzing the pH of umbilical cord arterial blood (pH<7.1). RESULTS No significant effect of the cardiotocography category on the arterial (p=0.543) and venous (p=0.770) pH of umbilical cord blood was observed. No significant association was observed between the cardiotocography category and the presence of fetal acidemia (p=0.706), 1-min Apgar score <7 (p=0.260), hospitalization in the neonatal intensive care unit (p=0.605), newborn death within the first 48 h, need for neonatal resuscitation (p=0.637), and adverse perinatal outcomes (p=0.373). Sensitivities of 62, 31, and 6.0%; positive predictive values of 11.0, 16.0, and 10.0%; and negative predictive values of 85, 89.0, and 87.0% were observed for cardiotocography categories I, II, and III, respectively. CONCLUSION The three categories of intrapartum cardiotocography presented low sensitivities and high negative predictive values to identify fetal acidemia at birth in low-risk pregnancies.

Abstract
PURPOSE The aim of the study was to estimate by a survival analysis model the hazard function (HF) for neonatal metabolic acidemia (MA) throughout the 2nd stage of labor (2STG) at the time of occurrence of a terminal bradycardia ≥ 10 min requiring expedited delivery, and the cumulative incidence function (CIF) for MA according with the duration of bradycardia stratified in 10-12 min and > 12 min. METHODS Singleton pregnancies experiencing terminal fetal bradycardia requiring expedited delivery in the 2STG at 38 + 0-41 + 3 weeks and delivering in the year 2019, were identified. The presence of MA (pH < 7 and/or BE ≤ - 12 mmol/L) was determined based on the acid-base status in the umbilical artery cord blood. Survival analysis was used to assess the hazard function (HF) and the cumulative incidence function (CIF) for MA occurring after terminal fetal bradycardia, at the 2STG. RESULTS Out of a non-consecutive population of 12,331 pregnancies, there were 52 cases that fit the inclusion criteria. Twenty-four (46.2%) of those develop MA. Abnormal quantitative pH values and the HF for MA correlated with the duration of 2STG at the time of bradycardia onset, but not with bradycardia duration. After 60 min of duration of 2STG, the HF (or instantaneous rate of failure) increased dramatically (from 1.2 to 20 about at 120 min). At paired duration of 2STG, a higher CIF was observed for the terminal bradycardia > 12 min. CONCLUSION Forty-six percent of term fetuses with terminal bradycardia had MA at birth. Despite the low sensitivity and a non-significant association with quantitative pH values, the duration of terminal bradycardia in the 2STG is associated with a higher CIF for MA.

Treatment of Fetal Arrhythmias. J Clin Med 2021; 10:jcm10112510.

Abstract
Fetal arrhythmias are mostly benign and transient. However, some of them are associated with structural defects or can cause heart failure, fetal hydrops, and can lead to intrauterine death. The analysis of fetal heart rhythm is based on ultrasound (M-mode and Doppler echocardiography). Irregular rhythm due to atrial ectopic beats is the most common type of fetal arrhythmia and is generally benign. Tachyarrhythmias are diagnosed when the fetal heart rate is persistently above 180 beats per minute (bpm). The most common fetal tachyarrhythmias are paroxysmal supraventricular tachycardia and atrial flutter. Most fetal tachycardias can be terminated or controlled by transplacental or direct administration of anti-arrhythmic drugs. Fetal bradycardia is diagnosed when the fetal heart rate is slower than 110 bpm. Persistent bradycardia outside labor or in the absence of placental pathology is mostly due to atrioventricular (AV) block. Approximately half of fetal heart blocks are in cases with structural heart defects, and AV block in cases with structurally normal heart is often caused by maternal anti-Ro/SSA antibodies. The efficacy of prenatal treatment for fetal AV block is limited. Our review aims to provide a practical guide for the diagnosis and management of common fetal arrythmias, from the joint perspective of the fetal medicine specialist and the cardiologist.
