Abstract
BACKGROUND Since its introduction, assisted reproductive technology (ART) has developed into a common clinical practice around the world; yet it still raises a lot of questions. Throughout time, many researchers have investigated its association with several obstetric incidences and its consequences on perinatal outcomes. The aim of the current meta-analysis was to estimate the correlation between ART procedures and malpresentation of the fetus in singleton pregnancies. METHODS The study was conducted according to the Preferred Reporting Items of Systematic Reviews and Meta-analyses (PRISMA) guidelines and prospectively registered under the PROSPERO database (CRD42023458084). Five databases (Embase, MEDLINE®, APA PsycInfo, Global Health, Health Management Information Consortium (HMIC)) and two additional sources were searched from inception to 31 May 2023. Quality of the included studies was assessed using the ROBINS-1 scale, whilst quality of evidence by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. Summative and subgroup data as well as heterogeneity were generated by the Cochrane platform RevMan Web. RESULTS Overall, 11 studies were included in the study with a total of 3,360,134 deliveries. Results indicate a higher risk of malpresentation at delivery in fetuses conceived through ART than those conceived naturally (RR: 1.50, (95% confidence interval (CI):1.30, 1.73)). This risk decreased when adjustments for potential confounders were applied (RR = 1.12, 95% CI 1.02, 1.23). CONCLUSIONS Based on observational studies, this meta-analysis indicated that singleton pregnancies conceived through ART are associated with higher risk of malpresentation than those conceived naturally, albeit the difference was lower when potential confounders were examined. Thus, future large studies are required to better understand possible reversible and irreversible factors of this relationship.

Abstract
Assisted reproductive technologies (ARTs) such as in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) are still discussed critically, as there is no consensus on whether these treatments could be the cause of risk factors for obstetric problems such as breech presentation. The aim of this study was to test the association between ART and breech presentation among 11920 singleton term births taking place in Vienna from 2010 to 2020. In this single-centre medical record-based study, data concerning the conception mode (spontaneous versus IVF or ICSI), child presentation, birth mode, newborn sex and size as well as age, height, weight, and reproductive history of the mother were included. Three hundred twenty-six newborns (2.7%) were conceived by IVF or ICSI, and 527 newborns (4.4%) were delivered in breech presentation. Breech presentation occurred in 7.6% of IVF/ICSI children but only in 4.3% of spontaneously conceived children (P = 0.019). ART increased the crude risk of breech presentation significantly (OR = 1.67; 95% CI 1.71 - 2.38). After adjusting for maternal age, height, number of previous births, smoking, and newborn sex, however, ART had no longer a significant impact on the risk of breech presentation. In contrast, breech presentation was significantly associated with higher maternal age as well as a lower number of previous births, but not with ART. This study shows that the adverse outcomes of IVF and ICSI pregnancies may not be due to the ART treatment alone but might also be due to the mostly higher age and lower parity of the mothers using ART.

Abstract
PURPOSE This study aims to evaluate the level of psychological distress for women with breech compared to cephalic presentation. We hypothesized, that women with breech presentation have higher levels of depression, stress and anxiety. Secondary objectives were to analyze potential demographic risk factors and comorbidity of psychological distress in breech pregnancy. METHODS The breech study group was formed by 379 women with breech presentation. A sample of 128 women with cephalic presentation was recruited during routine clinical care. Depression, anxiety and stress symptoms were ascertained by means of the Depression-Anxiety-Stress-Score (DASS)-21 questionnaire. Categorial data was analyzed with Chi-square or exact test, continuous data with unpaired t test or Mann-Whitney U test. Demographic risk factors were identified using a binary logistic regression model. RESULTS Prevalence of psychological distress among women with breech was not higher compared to those of other pregnant women. Symptomatic depression, anxiety and stress affected 5.8%, 14.5% and 11.9% of women with breech, respectively. Decreasing age was identified as a risk factor for anxiety (p = 0.006). Multiparity increased risk for depression (p = 0.001), for anxiety (p = 0.026) and for perinatal stress (p = 0.010). More than 80% of women with depressive symptoms had comorbidities of psychological distress. CONCLUSIONS Breech presentation compared to cephalic presentation was not associated with higher levels of psychological distress. However, breech pregnancies are affected by symptoms of potential mental disorder. Multiparous women and younger women may need additional support and would benefit from a standardized screening tool for the assessment of perinatal psychological distress. CLINICAL TRIAL REGISTRATION Ethical approval (EA2/241/18) was granted by the Ethics Commission of the Charité University Hospital on the 23.01.2019 (ClinicalTrials.gov Identifier: NCT03827226).

Abstract
Background In many countries, vaginal breech labor at term is an option in selected cases. However, the safety of vaginal breech labor in preterm is still unclear. Therefore our study aimed to evaluate the safety of vaginal breech labor in late preterm deliveries. Design A retrospective register-based study. Setting Maternity hospitals in Finland, 2004–2017. Participants The study population included 762 preterm breech deliveries at 32 + 0—36 + 6 gestational weeks according to the mode of delivery, 535 (70.2%) of them were born vaginally in breech presentation, and 227 (29.8%) were delivered by non-urgent cesarean section. Methods The study compared short-term neonatal adverse outcomes of singleton vaginal breech deliveries with non-urgent cesarean deliveries at 32 + 0 to 36 + 6 weeks of gestation. An odd ratio with 95% confidence intervals was calculated to estimate the relative risk of adverse outcomes. Outcome measures Neonatal death, an arterial umbilical pH below seven, a five-minute Apgar score below four and seven, admission to neonatal intensive care unit, neonatal intubation, neonatal antibiotic therapy, neonatal birth trauma, respiratory distress syndrome, neonatal convulsions, cerebral ischemia, hypoxic-ischemic encephalopathy, congenital hypotonia, and a composite of severe adverse outcomes. Results A five-minute Apgar scores below seven were increased in vaginal breech labor at 32 + 0 to 36 + 6 weeks of gestation compared to non-urgent cesarean sections (aOR 2.48, 95% CI 1.08–5.59). Neonatal antibiotic therapy, the admission to neonatal intensive care unit, and neonatal respiratory distress syndrome were decreased after vaginal breech labor compared to the outcomes of non-urgent cesarean section (neonatal antibiotic therapy aOR 0.60, 95% CI 0.40–0.89; neonatal NICU admission aOR 0.47, 95% CI 0.33–0.68; respiratory distress syndrome aOR 0.30, 95% CI 0.19–0.48). Conclusion Vaginal breech labor at 32 + 0—36 + 6 gestational weeks does not increase severe neonatal short-term morbidity or mortality compared to cesarean section.

Abstract
AIMS To address the rate of spontaneous version in breech presentation until term and explore the risk factors for persistent breech presentation diagnosed by the second-trimester ultrasound examination. METHODS This is a retrospective cohort study of pregnant women with a singleton pregnancy who had their ultrasound examination conducted at the time of 22-26 weeks of gestation in the Guangzhou Women and Children's Medical Center. Cox regressions were applied to determine the strength of association between selected risk factors and persistent breech presentation. RESULTS Among 25,313 pregnant women eligible for analysis, the prevalence of breech presentation was 36.8% (9,306/25,313) at 22-26 weeks of gestation, 4.2% (376/8,876) of which would remain in the breech presentation at the onset of labor (adjusted odds ratio [aOR], 0.39, 95% confidence interval [CI], 0.17-0.88). Multiparity (aOR, 0.39, 95% CI, 0.30-0.52) and longer gestational weeks at delivery (aOR, 0.50, 95% CI, 0.44-0.56) were associated with a lower risk of persistent breech presentation (PBP). Female fetus, lateral or fundal placenta, and known uterine malformation was each associated with an increased odd of 1.4 (aOR, 95% CI, 1.11-1.70), 2.4 (aOR, 95% CI,1.50-3.73), 3.1 (aOR, 95% CI, 1.71-5.53) and 8.7 (aOR, 95% CI, 3.84-19.84) times in the persistent breech presentation, respectively. CONCLUSION The prevalence of the breech presentation was 36.8% between 22 and 26 weeks of gestation, and approximately 4% would have been in the persistent breech presentation until the onset of labor. Higher educational attainment, multiparity and longer gestational weeks at delivery were significantly decreasing the risk of persistent breech presentation. While the pregnant women with age >40 years, female fetus, lateral or fundal placenta and known uterine malformation were associated increased risk of persistent breech presentation.

Race and ethnicity are among the predisposing factors for fetal malpresentation at term. Am J Obstet Gynecol MFM 2021; 3:100405. [PMID: 34091061 DOI: 10.1016/j.ajogmf.2021.100405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/21/2021] [Accepted: 05/25/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Fetal malpresentation complicates approximately 3% to 4% of all term births. It requires special considerations for delivery and exposes the mother and neonate to obstetrical interventions and potential adverse outcomes, such as umbilical cord prolapse, head entrapment and birth trauma, hypoxic ischemic encephalopathy, cesarean delivery, and cesarean delivery-related complications. We set out to explore the maternal and fetal factors associated with noncephalic malpresentation at term, with specific interest on the impact of maternal race and ethnicity on fetal malpresentation. STUDY DESIGN This was a retrospective analysis of the Centers for Disease Control and Prevention Natality Live Birth database for the years from 2016 through 2018. All term, singleton deliveries for the following racial and ethnic groups were included: non-Hispanic White, non-Hispanic Black, Asian, and Hispanic. Race and ethnicity were assigned based on self-identification and individuals with >1 racial category were excluded from the analysis. Malpresentation was defined as a noncephalic presentation at term and included breech and transverse presentations. The malpresentation group included all noncephalic births and cephalic births that occurred following successful external cephalic version, whereas all other cephalic births served as controls. A multivariable logistic regression analysis was used to assess the rate of malpresentation, with adjustment for potential confounders including maternal age, race and ethnicity, parity, birthweight, fetal malformations, malformations of the central nervous system (CNS), and chromosomal anomalies. The results are displayed as adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Statistical significance was set at a P value of <.05. Institutional review board approval was not required because the de-identified data are publicly available through a data use agreement. RESULTS There were 9,692,203 term, singleton births during the study period. The malpresentation group included 354,689 births (3.66% of the total). The Table shows the rate of malpresentation for various maternal and fetal factors. We found a substantial racial and ethnic disparity in the malpresentation rates. Non-Hispanic White women had the highest malpresentation risk, whereas non-Hispanic Black women had the lowest risk (3.93% vs 2.81%; aOR, 1.38; 95% CI, 1.36-1.39). Hispanic and Asian women were also at increased risk for malpresentation when compared with non-Hispanic Black women (aOR, 1.30; 95% CI, 1.29-1.32 and aOR, 1.12; 95% CI, 1.10-1.14, respectively). In addition, several maternal and fetal conditions were noted to be associated with an increased risk for malpresentation at term, including older maternal age (aOR, 2.81; 95% CI, 2.74-2.88; for patients >40 years), nulliparity (aOR, 1.50; 95% CI, 1.48-1.51), low birthweight (aOR, 1.80; 95% CI, 1.77-1.83 for birthweight under 2500 g), and fetal malformations of the CNS and chromosomal anomalies (aOR, 3.53; 95% CI, 3.06-4.06 and aOR, 2.32; 95% CI, 2.05-2.63, respectively). CONCLUSION Based on a large US population database, we identified several maternal, fetal, and racial and ethnic factors that are associated with an increased rate of noncephalic malpresentation at term. Specifically, fetal CNS malformations, congenital or chromosomal anomalies, advanced maternal age, low birthweight, and nulliparity are risk factors for noncephalic presentation. Interestingly, non-Hispanic White women have the highest risk for malpresentation, whereas non-Hispanic Black women have the lowest risk. Previous publications found that low birthweight, advanced maternal age, nulliparity, and congenital fetal malformations are risk factors for malpresentation.1-3 Nonetheless, the current data available on race and ethnicity are sporadic, with limited reports suggesting that sub-Saharan ethnicity is associated with a lower rate of malpresentation2 and that White race is associated with a higher rate.4 We present a large-scale, nationwide US-based study to confirm the racial and ethnic disparity regarding malpresentation in the United States. This may be explained by the known variation in the shape of the bony birth canal in different racial and ethnic groups and populations from different geographic locations.5 Further investigation is needed to explore the racial and ethnic disparity described.
