RESUMO
Progestin-primed ovarian stimulation (PPOS) is being increasingly used for ovarian stimulation in assisted reproductive technology. Different progestins have been used with similar success. The available studies suggest a similar response to ovarian stimulation with gonadotrophin-releasing hormone (GnRH) analogues. Any differences in the duration of stimulation or gonadotrophin consumption are minor and clinically insignificant. PPOS has the advantage of oral administration and lower medication costs than GnRH analogues. As such it is clearly more cost-effective for fertility preservation and planned freeze-all cycles, but when fresh embryo transfer is intended PPOS can be less cost-effective depending on the local direct and indirect costs of the additional initial frozen embryo transfer cycle. Oocytes collected in PPOS cycles have similar developmental potential, including blastocyst euploidy rates. Frozen embryo transfer outcomes of PPOS and GnRH analogue cycles seem to be similar in terms of both ongoing pregnancy/live birth rates and obstetric and perinatal outcomes. While some studies have reported lower cumulative live birth rates with PPOS, they have methodological issues, including arbitrary definitions of the cumulative live birth rate. PPOS has been used in all patient types (except progesterone receptor-positive breast cancer patients) with consistent results and seems a patient friendly and cost-effective choice if a fresh embryo transfer is not intended.

OBJECTIVE: The objective of the meta-analysis was to determine the influence of uterine fibroids on adverse outcomes, with specific emphasis on multiple or large (≥ 5 cm in diameter) fibroids. MATERIALS AND METHODS: We searched PubMed, Embase, Web of Science, ClinicalTrials.gov, China National Knowledge Infrastructure (CNKI), and SinoMed databases for eligible studies that investigated the influence of uterine fibroids on adverse outcomes in pregnancy. The pooled risk ratio (RR) of the variables was estimated with fixed effect or random effect models. RESULTS: Twenty-four studies with 237 509 participants were included. The pooled results showed that fibroids elevated the risk of adverse outcomes, including preterm birth, cesarean delivery, placenta previa, miscarriage, preterm premature rupture of membranes (PPROM), placental abruption, postpartum hemorrhage (PPH), fetal distress, malposition, intrauterine fetal death, low birth weight, breech presentation, and preeclampsia. However, after adjusting for the potential factors, negative effects were only seen for preterm birth, cesarean delivery, placenta previa, placental abruption, PPH, intrauterine fetal death, breech presentation, and preeclampsia. Subgroup analysis showed an association between larger fibroids and significantly elevated risks of breech presentation, PPH, and placenta previa in comparison with small fibroids. Multiple fibroids did not increase the risk of breech presentation, placental abruption, cesarean delivery, PPH, placenta previa, PPROM, preterm birth, and intrauterine growth restriction. Meta-regression analyses indicated that maternal age only affected the relationship between uterine fibroids and preterm birth, and BMI influenced the relationship between uterine fibroids and intrauterine fetal death. Other potential confounding factors had no impact on malposition, fetal distress, PPROM, miscarriage, placenta previa, placental abruption, and PPH. CONCLUSION: The presence of uterine fibroids poses increased risks of adverse pregnancy and obstetric outcomes. Fibroid size influenced the risk of breech presentation, PPH, and placenta previa, while fibroid numbers had no impact on the risk of these outcomes.

BACKGROUND: Although pregnancy complicated by liver cirrhosis is rare, women with cirrhosis experience increased adverse pregnancy outcomes. This study aimed to evaluate pregnancy outcomes in women with liver cirrhosis and develop a predictive model using maternal factors for preterm birth in such pregnancies. METHODS: A retrospective analysis was conducted on pregnancy outcomes of a cirrhosis group (n = 43) and a non-cirrhosis group (n = 172) in a university hospital between 2010 and 2022. Logistic regression evaluated pregnancy outcomes, and a forward stepwise logistic regression model was designed to predict preterm birth in pregnant women with cirrhosis. The model's predictive performance was evaluated using the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC). RESULTS: The incidence of cirrhosis during pregnancy was 0.06% (50/81,554). Pregnant women with cirrhosis faced increased risks of cesarean section, preterm birth, intrahepatic cholestasis of pregnancy, thrombocytopenia, and postpartum hemorrhage. In pregnant women with cirrhosis, preterm birth risk significantly increased at an incidence rate of 46.51% (20/43). According to the prediction model, the key predictors of preterm birth in pregnant women with cirrhosis were intrahepatic cholestasis of pregnancy and total bilirubin. The model demonstrated accurate prediction, with an AUC of 0.847, yielding a model accuracy of 81.4%. CONCLUSIONS: Pregnant women with cirrhosis face a heightened risk of adverse obstetric outcomes, particularly an increased incidence of preterm birth. The preliminary evidence shows that the regression model established in our study can use the identified key predictors to predict preterm birth in pregnant women with cirrhosis, with high accuracy.

BACKGROUND: The research was conducted to evaluate the birth and newborn outcomes of Syrian immigrant women according to maternal age groups and Vitamin D use. METHODS: It was conducted retrospectively using the birth records of 2,866 Syrian migrant women, who had given birth at a tertiary center between January 2016 and May 2020. Demographic features, obstetric and neonatal outcomes were analyzed according to age groups and Vitamin D use. RESULTS: The mean age of the patients included in the study was 26.22 ± 5.90, the mean gestational age at birth was 38.06 ± 2.1 weeks, and the mean newborn birth weight was 3.151 g. The mean hemoglobin value of the patients was 11.55 ± 1.54. While most of the patients were taking iron supplements (80.59%), Vitamin D (Vit D) supplement intake was 38.31%. The mean number of antenatal follow-ups was 3.40 ± 1.65. While the most common delivery method was normal vaginal delivery (61.93%), cesarean section rates were found to be 38.07%. The need for blood transfusion was significantly lower in the group that had received Vitamin D than that in the group that had not received it (2.00% vs. 8.94% p < 0.001). The rate of preterm birth was found to be 5.74% in the group that had received Vitamin D and 9.28% in the group that had not received it, which was significantly higher (p < 0.001). CONCLUSIONS: We have seen that maternal and fetal outcomes can be improved with hospital follow-up and adequate vitamin supplements in refugee pregnant women.

OBJECTIVES: Term oligohydramnios is linked to pregnancy complications. We previously presented the outcome of the low-risk population (no pregnancy complications) with term oligohydramnios. This study aims to address the high-risk group (Any maternal complication during pregnancy, such as gestational diabetes, pre-gestational diabetes, chronic hypertension, preeclampsia, anemia, asthma, obesity, and multi parity.). METHODS: This retrospective cohort study of 1,114 singleton term (≥37), oligohydramnios (AFI <50â¯mm) pregnancies from Shamir Medical Center between 2017 and 2021. Compering the low-risk to high-risk groups with subdivision by severity of oligohydramnios. RESULTS: A total of 211 subjects (19â¯%) were high-risk cases and 903 (81â¯%) low-risk cases. Comparing these two groups, subjects of the high-risk group were older (31.34 ± 5.85 vs. 29.51 vs. 4.96), had earlier gestational age at delivery 39.53 ± 1.18 vs. 40, had higher mean AFI (35 ± 12.7 vs. 33 ± 14.5), were subject to more labor inductions (81 vs. 69.7â¯%), and CS rate (19.9 vs. 12.4â¯%). Logistic regression revealed a need for more cesarean sections in the high-risk group. Additionally, more labor inductions and a higher risk of negative fetal outcomes. CONCLUSIONS: This study highlights the importance of considering pregnancy risk factors when we are approaching oligohydramnios in high-risk pregnancies.
RESUMO
INTRODUCTION: Antithrombin (AT) deficiency is a rare but highly thrombogenic inherited thrombophilia. Its association with adverse pregnancy outcomes (APO) is undefined. There is limited guidance on managing AT deficiency in pregnancy. Some significant issues remain controversial, including risk assessment for prophylactic anticoagulation, anticoagulant therapy, and monitoring. Our goal was to examine if the antepartum management of patients with AT deficiency affected their pregnancy outcomes. MATERIALS AND METHODS: This retrospective, single-center observational study included pregnant women with inherited AT deficiency in Peking Union Medical College Hospital between 2013 and 2024. RESULTS: Seventeen pregnancies in 6 women with AT deficiency were identified. A total of 7 pregnancies received adjusted-dose low-molecular-weight heparin (LMWH) and were monitored by anti-Xa level, AT activity, and D-dimer. There were 5 live births (all received LMWH), 7 second-trimester abortions (1 received LMWH), and 5 early pregnancy losses (1 received LMWH). There were 5 abruptio placentae events (3 received LMWH) and 7 thrombotic events (2 received LMWH). CONCLUSIONS: AT deficiency is at least an important partial factor contributing to APO. It is suggested to make a full assessment of AT patients both for venous thrombus embolism and APO risk. We observed a high prevalence of heparin resistance and a positive correlation between adequate anticoagulation and pregnancy outcome based on tight monitoring with anti-Xa level and timely adjustment of the LMWH dosage.
RESUMO
PURPOSE: This systematic review and meta-analysis aimed to explore the relationship of endometrial thickness (EMT) with obstetric and neonatal outcomes in assisted reproductive cycles. METHODS: PubMed, EMBASE, Cochrane Library and Web of Science were searched for eligible studies through April 2023. Obstetric outcomes include placenta previa, placental abruption, hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus (GDM) and cesarean section (CS). Neonatal outcomes include birthweight, low birth weight (LBW), gestational age (GA), preterm birth (PTB), small for gestational age (SGA) and large for gestational age (LGA). The effect size was estimated as odds ratio (OR) or mean difference (MD) with 95% confidence interval (CI) using a random-effects model. Inter-study heterogeneity was assessed by the chi-square homogeneity test. One-study removal method was used to determine the sensitivity of the meta-analysis. RESULTS: Nineteen studies involving 76,404 cycles were included. The pooled results revealed significant differences between the thin endometrium group and the normal group in placental abruption (OR = 2.45, 95% CI: 1.11-5.38, P = 0.03; I2 = 0%), HDP (OR = 1.72, 95% CI: 1.44-2.05, P < 0.0001; I2 = 0%), CS (OR = 1.33, 95% CI: 1.06-1.67, P = 0.01; I2 = 77%), GA (MD = -1.27 day, 95% CI: -2.41- -1.02, P = 0.03; I2 = 73%), PTB (OR = 1.56, 95% CI: 1.34-1.81, P < 0.0001; I2 = 33%), birthweight (MD = -78.88 g, 95% CI: -115.79- -41.98, P < 0.0001; I2 = 48%), LBW (OR = 1.84, 95% CI: 1.52-2.22, P < 0.00001; I2 = 3%) and SGA (OR = 1.41, 95% CI: 1.17-1.70, P = 0.0003; I2 = 15%). No statistical differences were found in placenta previa, GDM, and LGA. CONCLUSION: Thin endometrium was associated with lower birthweight or GA and higher risks of placental abruption, HDP, CS, PTB, LBW and SGA. Therefore, these pregnancies need special attention and close follow-up by obstetricians. Due to the limited number of included studies, further studies are needed to confirm the results.

RESEARCH QUESTION: Does the maternal ABO blood type affect obstetric and perinatal outcomes following frozen embryo transfer (FET)? DESIGN: A retrospective study was performed at a university-affiliated fertility centre, involving women with singleton and twin deliveries conceived by FET. Subjects were divided into four groups based on ABO blood type. The primary end-points were obstetric and perinatal outcomes. RESULTS: A total of 20,981 women were involved, with 15,830 having singletons and 5151 delivering twins. In singleton pregnancies, women with blood group B had a slight but significantly increased risk of gestational diabetes mellitus compared to women with blood group O (adjusted odds ratio [aOR] 1.16; 95% confidence interval [CI] 1.01-1.34). Furthermore, singletons born to women with the B antigen (blood type B or AB) were more likely to be large for gestational age (LGA) and with macrosomia. In twin pregnancies, blood type AB was related to a decreased risk of hypertensive diseases of pregnancy (aOR 0.58; 95% CI 0.37-0.92), while blood type A was associated with a higher risk of placenta praevia (aOR 2.04; 95% CI 1.15-3.60). When compared with the O blood group, twins from the AB blood group had a lower risk of low birthweight (aOR 0.83; 95% CI 0.71-0.98) but a higher risk of LGA (aOR 1.26; 95% CI 1.05-1.52). CONCLUSIONS: This study demonstrates that the ABO blood group may influence the obstetric and perinatal outcomes for both singletons and twins. These findings emphasize that patient characteristics could be, at least partly, responsible for adverse maternal and birth outcomes following IVF.

RESEARCH QUESTION: Does type of culture medium used influence obstetric and perinatal outcomes after vitrified-warmed single blastocyst transfers? DESIGN: Retrospective cohort study involving singletons after vitrified-warmed single blastocyst embryo transfers, using embryos cultured in either Irvine Continuous Single Culture medium (CSC) or Vitrolife G5TM PLUS medium culture system between 2013 and 2020. RESULTS: A total of 2475 women who had singleton deliveries were included for final analysis: 1478 had embryos cultured in CSC and 997 had embryos cultured in G5TM PLUS medium. Birth outcomes, including preterm birth, mean birth weight, gestational age- and sex-adjusted birth weight (Z-scores), rates of large-for-gestational-age, small-for-gestational-age, low birth weight and macrosomia, and the distribution of newborn gender did not differ significantly between groups in crude and adjusted analyses. Women whose embryos were cultured in G5TM PLUS frequently suffered from pregnancy-induced hypertensive disorders compared with those who had embryos cultured in CSC (4.7% versus 3.0%; Pâ¯=â¯0.031). This difference was no longer significant after adjusting for several key confounders (adjusted odds ratio 1.49, 95% CI 0.94 to 2.38, Pâ¯=â¯0.087). Other obstetric complications, including gestational diabetes mellitus, preterm premature rupture of membranes, abnormal placentation, postpartum haemorrhage and the mode of delivery were all similar between the two groups. CONCLUSIONS: The present study adds new information to the current evidence by suggesting that the embryo culture medium does not affect birth outcomes and obstetric complications when comparison is limited to Irvine CSC and Vitrolife G5TM PLUS in vitrified-warmed single blastocyst transfer cycles.

PURPOSE: Several studies indicate that assisted reproductive technology (ART) including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies carries increased risk of complications including postpartum hemorrhage (PPH). However, the association between IVF/ICSI and the bleeding risk particularly in cesarean delivery has not been systematically assessed. The aim of this study was to evaluate bleeding risk during and after cesarean delivery in parturients who conceived using IVF or ICSI. METHODS: This is a retrospective observational study analyzing data from 310 parturients who underwent cesarean delivery: 155 who had conceived using IVF or ICSI (IVF/ICSI group) and 155 age and year of delivery matched controls who had conceived spontaneously (control group). The primary outcome measure was the amount of blood lost during and within 24 h after cesarean delivery. Secondary outcome measure was the incidence of severe PPH. With 132 parturients in each group, we had 90% power to detect a 200 mL difference in the bleeding amount, at a 0.05 two-sided significance level. RESULTS: The amount of bleeding in the IVF/ICSI group was 1234 ± 669 mL, which was 124 mL (11.2%) greater than that in the control group (95% CI - 34 to 282; p = 0.12). The incidence of severe PPH in the IVF/ICSI group and in the control group was 23.9% and 16.8%, respectively (p = 0.16), and the unadjusted odds ratio was 1.6 (95% CI, 0.9-2.7; p = 0.12). No significant independent effect of IVF/ICSI on the bleeding amount and the incidence of severe PPH was observed in multivariable regression analyses (p = 0.22, p = 0.16). CONCLUSION: In this study, IVF and ICSI were not associated with increasing risk of bleeding in cesarean delivery.

BACKGROUND: To investigate the association of clinical characteristics at the time of non-hysteroscopic myomectomy before pregnancy and adverse obstetric outcomes in the next pregnancy. METHODS: In this retrospective cohort study, we identified 248 women who underwent abdominal or laparoscopic myomectomy for intramural (IM) and/or subserosal (SS) uterine myomas in Bundang CHA Medical Center before pregnancy and delivered at the same hospital between 2010 and 2020. The association between clinical characteristics at the time of myomectomy and subsequent obstetric outcomes was analyzed using the Chi-square test, the Student t-test or one-way ANOVA, and multivariable analysis. RESULTS: There was one case of uterine rupture. The gestational age at delivery was 37.7 ± 2.4 weeks. There were 2 (0.8%) cases of fetal loss before 23 weeks, but there were no cases of perinatal death. The risk of transfusion during or after delivery was higher in the group in which multiple myomas were removed compared to the group in which only one was removed (aOR = 2.41, 95% CI [1.20-4.86], p = 0.014). The risk of neonatal composite morbidity was higher in the group in which myomas including the IM type were removed, than in the group in which only SS myomas were removed (aOR = 14.29, 95% CI [1.82-99.57], p = 0.012). Although not statistically significant, the group in which the sum of the diameters of the three largest myomas was greater than 15 cm showed a higher frequency of preterm birth (19.3% vs. 10.1%, p = 0.001) and lower birth weight (2901 ± 625 g vs. 3063 ± 576 g, p = 0.001) compared to the group with diameters less than 15 cm. Placenta accreta/increta (7.9% vs. 3.8%, p = 0.043) and lower placental weight (646 ± 170 g vs. 750 ± 232 g, p = 0.034) were more common in patients with an interval between myomectomy and pregnancy of less than 12 months compared to more than 12 months. CONCLUSIONS: To our knowledge, this is the first study to investigate the association between clinical features at the time of myomectomy before pregnancy and various adverse obstetric and perinatal outcomes. If the removed myomas are multiple, IM, large, or the interval between myomectomy and pregnancy is short, the risk of obstetric and neonatal complications may increase.

BACKGROUND: Direct obstetric causes account for nearly 75% of all maternal deaths. Controversy prevails in the effect of grand multiparity on adverse obstetric outcomes. This study thus aimed to determine and compare the obstetric outcomes in low multiparous (LM) and grand multiparous (GM) women in Public Hospitals of North Ethiopia. METHOD: An institution-based comparative cross-sectional study was done among 540 (180 GM and 360 LM) participants from January 1 to March 30, 2021. The data was collected through face-to-face interviews and a review of clinical records and birth registries. Epi-Data version 4.6 was used for data entry and analysis was performed using SPSS version 25.0 statistical software. A p-value of ≤ 0.05 (2-tailed) was used to consider the significance of statistical tests. RESULT: The prevalence of adverse obstetric outcomes was 32.6% (95% CI: 28.7-36.5). Antepartum hemorrhage, anemia, and postpartum hemorrhage were higher in grand multiparous women. Whereas, prolonged labor, induction/augmentation, prelabor rupture of membrane, episiotomy, and post-term pregnancy was higher in low multiparous women. Income (AOR (CI) = 3.15 (1.30-7.63), alcohol consumption (AOR (CI) = 3.15 (1.49-6.64), preterm delivery (AOR (CI) = 9.24 (2.28-27.3), cesarean delivery (AOR (CI) = 13.6 (6.18-30.1), and low birth weight (AOR (CI) = 3.46 (1.33-9.03) significant predictors of adverse obstetric outcomes. However, parity did not show a statistically significant difference in obstetric outcomes. CONCLUSION: In the study area, obstetric complications were high compared to a systematic review and meta-analysis study done in the country (26.88%). Socio-economic status, alcohol consumption, gestational age at delivery, mode of delivery, and birth weight were significant associates of the obstetric outcome. There was no statistically significant difference in obstetric outcomes between GM and LM women. Socio-economic development, avoiding alcohol consumption, early identification and treatment of complications, and adequate nutrition and weight gain during pregnancy are needed regardless of parity.

BACKGROUP: Frozen-thawed embryo transfer is rising worldwide. One adverse effect of programmed frozen embryo transfer (FET) reported in some studies is an increased risk of adverse obstetric and perinatal outcomes. Meanwhile, body mass index (BMI) also has adverse effect on obstetric and perinatal outcomes. In this study, we investigated that the influence of different endometrial preparation protocols on obstetric and perinatal outcomes and the role of BMI in it. METHOD: This retrospective cohort study included 2333 singleton deliveries after frozen-thaw embryo transfer at our centre between 2014 and 2021, including 550 cycles with programmed FET, 1783 cycles with true natural cycle FET (tNC-FET). In further analysis according to BMI grouped by Asian criterion, group A (18.5 kg/m2 ≤ BMI < 24.00 kg/m2) included 1257 subjects, group B (24 kg/m2 ≤ BMI < 28.00 kg/m2) included 503 subjects and group C (BMI ≥ 28 kg/m2) included 573 subjects. Baseline characteristics of the two groups were compared and analyzed. Binary logistic regression analyses were performed to explore the association between obstetric and perinatal outcomes and endometrial preparation protocols. RESULTS: There were no significant differences in the placenta previa, gestational diabetes mellitus(GDM), preterm premature rupture of membranes (PPROM), cesarean section (CS) and macrosomia between the tNC-FET and programmed FET groups (P > 0.05). The programmed FET cycles were associated to a higher risk of pregnancy-induced hypertension (PIH) compared with the tNC-FET cycles (7.3% vs 4.4%, crude OR 1.71[1.16-2.54]; adjusted OR 1.845[1.03-3.30]). After dividing the patients into three groups according to the BMI, The programmed FET cycles were associated to a higher risk of PIH in group C (14.4% vs 6.2%, crude OR 2.55 [1.42-4.55]; adjusted OR 4.71 [1.77-12.55]) compared with the tNC-FET cycles. But there was no statistically significant difference in group A and group B. Programmed FET group compared with the tNC-FET group, the risk of PIH increase as the body mass index increase. CONCLUSION: This study showed a tendency toward increasing risk of PIH in programmed FET cycle compared with the tNC-FET cycle, and the risk of PIH increases as BMI increases. Increased risk of preterm birth and low birth weight is linked to increased risk of PIH.

OBJECTIVE: The aim of this study was to define the population of pregnant women who presented to our clinic after drug exposure for suicidal purposes and to determine the effect of drug-induced poisoning on maternal and fetal outcomes. METHODS: The records of patients who presented to the emergency department after a suicide attempt with drugs between 2017 and 2021 were retrospectively reviewed. Pregnant women aged 18 years and over who delivered their babies in our hospital were included in the study. Patient data were obtained from the hospital electronic database using the International Classification of Disease-10 code system. Demographic information, clinical characteristics, type of drugs ingested, pregnancy outcomes, and perinatal outcomes were recorded. RESULTS: We found adverse pregnancy outcomes in five of the 28 patients included in the study. The most frequently used drugs for suicidal purposes were non-opioid analgesics, paracetamol, and antibiotics (39.3%, 35.7%, and 28.6%, respectively). Adverse pregnancy outcomes observed in the patients were preterm birth (n = 3), preeclampsia (n = 2), premature rupture of membranes (n = 1), fetal distress (n = 2), small for gestational age (n = 2), Apgar score at 5 min < 7 (n = 1), and requirement of neonatal intensive care (n = 2). CONCLUSION: Pregnant women attempting suicide with drug exposure are at high risk of many adverse obstetric outcomes. Providing these patients with appropriate clinical care is critical for the health of the mother and fetus.

INTRODUCTION: This study determined the prevalence, obstetric characteristics and pregnancy outcomes in teenagers who delivered at a secondary health facility in a Southern State in Nigeria. MATERIALS AND METHODS: A retrospective study was employed to review pregnancies that were managed in Central Hospital Warri, Delta State, Nigeria between 2014-2017. Patients' notes were retrieved and analyzed with respect to the socio-demographic characteristics, pregnancy, labor and delivery complications and fetal outcome. Chi-square test was used to test the association between the independent variables and the main outcomes of the study with statistical significance set at p<0.05. RESULTS: Out of the 14,067 pregnancies reviewed, the prevalence of teenage pregnancy was 2.8%. The mean age of the teenagers was 17.5 (±1.4) years, 243 (61.5%) of them had completed secondary school. Majority 286 (72.4%) delivered via spontaneous vaginal delivery, while 73 (18.5%) and 36 (9.1%) delivered via caesarean section and instrumental delivery respectively. The commonest complications encountered among the pregnant teenagers were perineal laceration (23.3%), iron deficiency anemia (17%) and delivery of low birth weight infant (14.9%). The younger teenagers were twice at risk of iron deficiency anaemia {OR (95%CI); p = 2.60 (1.08-5.92); p=0.028}. A similar association was seen between the age of the teenagers and route of delivery {OR (95%CI); p = 3.11 (1.34-6.93); p=0.002}, delivery of low birth weight infant {OR (95%CI); p = 3.12 (1.28-7.15); p=0.003} and perineal laceration {OR (95%CI); p = 2.54 (1.13-5.55); p=0.010}. CONCLUSION: Teenage pregnancy is associated with high risk of complications, especially among younger teenagers. Increasing public awareness as well as improving educational, socio- economic and reproductive health opportunities for adolescent girls is recommended.

MATÉRIEL ET MÉTHODES: Une étude rétrospective a été employé pour examiner les grossesses prises en charge à l'hôpital central de Warri dans l'État du Delta, au Nigeria, entre 2014 et 2017. Les notes des patientes ont été récupérées et analysées en ce qui concerne les caractéristiques sociodémographiques, la grossesse, les complications et l'issue fÅtale. Le test du chi-deux a été utilisé pour testé l'association entre les variables indépendantes et les principaux résultats de l'étude, la signification statistique étant fixée à p<0,05. RÉSULTATS: Sur les 14 067 grossesses examinées, la prévalence de la grossesse chez les adolescentes était de 2,8 %. L'âge moyen des adolescentes était de 17,5 (±1,4) ans, 243 (61,5%) d'entre elles avaient terminé l'école secondaire. La majorité des 286 (72,4 %) ont accouché par accouchement vaginal spontané, 73 (18,5 %) et 36 (9,1 %) ont accouché par césarienne et par accouchement instrumental respectivement. Les complications les plus courantes rencontrées chez les adolescentes enceintes ont été les lacérations périnéales (23,3%), l'anémie ferriprive (17 %) et l'accouchement d'un enfant de faible poids de naissance (14,9 %). Les adolescentes les plus jeunes étaient deux fois plus exposées au risque d'anémie ferriprive {OR (95%CI); p = 2,60 (1,085,92); p=0,028}. Une association similaire a été observée entre l'âge des adolescents et la voie d'accouchement {OR (95%CI); p = 3,11 (1,346,93); p=0,002}, l'accouchement d'un enfant de faible poids de naissance {OR (95%CI); p =3,12 (1,287,15); p=0,003} et lacération périnéale {OR (95%CI); p = 2,54 (1,135,55); p=0,010}. CONCLUSION: La grossesse chez les adolescentes est associée à un risque élevé de complications, en particulier chez les jeunes adolescentes. La sensibilisation du public ainsi que l'amélioration de l'éducation, socio-économiques et de santé reproductive pour les adolescentes est recommandée.

AIMS/HYPOTHESIS: Gestational diabetes mellitus (GDM) is generally defined based on glycaemia during an OGTT, but aetiologically includes women with defects in insulin secretion, insulin sensitivity or a combination of both. In this observational study, we aimed to determine if underlying pathophysiological defects evaluated as continuous variables predict the risk of important obstetric and neonatal outcomes better than the previously used dichotomised or categorical approaches. METHODS: Using data from blinded OGTTs at mean gestational week 28 from five Hyperglycemia and Adverse Pregnancy Outcome study centres, we estimated insulin secretion (Stumvoll first phase) and sensitivity (Matsuda index) and their product (oral disposition index [DI]) in 6337 untreated women (1090 [17.2%] with GDM as defined by the International Association of Diabetes and Pregnancy Study Groups). Rather than dichotomising these variables (i.e. GDM yes/no) or subtyping by insulin impairment, we related insulin secretion and sensitivity as continuous variables, along with other maternal characteristics, to obstetric and neonatal outcomes using multiple regression and receiver operating characteristic curve analysis. RESULTS: Stratifying by GDM subtype offered superior prediction to GDM yes/no only for neonatal hyperinsulinaemia and pregnancy-related hypertension. Including the DI and the Matsuda score significantly increased the area under the receiver operating characteristic curve (AUROC) and improved prediction for multiple outcomes (large for gestational age [AUROC 0.632], neonatal adiposity [AUROC 0.630], pregnancy-related hypertension [AUROC 0.669] and neonatal hyperinsulinaemia [AUROC 0.688]). Neonatal hypoglycaemia was poorly predicted by all models. Combining the DI and the Matsuda score with maternal characteristics substantially improved the predictive power of the model for large for gestational age, neonatal adiposity and pregnancy-related hypertension. CONCLUSION/INTERPRETATION: Continuous measurement of insulin secretion and insulin sensitivity combined with basic clinical variables appeared to be superior to GDM (yes/no) or subtyping by insulin secretion and/or sensitivity impairment in predicting obstetric and neonatal outcomes in a multi-ethnic cohort.

STUDY QUESTION: Are transfer day, developmental stage and morphology of the competent blastocyst in pregnancies leading to live birth associated with preterm birth, birthweight, length at birth and sex of the child? SUMMARY ANSWER: A high score in blastocyst developmental stage and in trophectoderm (TE) showed a significant association with the sex of the child, while no other associations with obstetric outcomes were observed. WHAT IS KNOWN ALREADY: The association between blastocyst assessment scores and obstetric outcomes have been reported in small single-center studies and the results are conflicting. STUDY DESIGN, SIZE, DURATION: Multicenter historical cohort study based on exposure data (transfer day (blastocyst developmental stage reached by Day 5 or Day 6)) blastocyst developmental stage (1-6) and morphology (TE and inner cell mass (ICM): A, B, C)) and outcome data (preterm birth, birthweight, length at birth, and sex of the child) from women undergoing single blastocyst transfer resulting in a singleton pregnancy and live birth. PARTICIPANTS/MATERIALS, SETTING, METHODS: Data from 16 private and university-based facilities for clinical services and research were used. A total of 7246 women, who in 2014-2018 underwent fresh-embryo transfer with a single blastocyst or frozen-thawed embryo transfer (FET) with a single blastocyst resulting in a singleton pregnancy were identified. Linking to the Danish Medical Birth Registry resulted in a total of 4842 women with a live birth being included. Cycles with pre-implantation genetic testing and donated gametes were excluded. The analyses were adjusted for female age (n = 4842), female BMI (n = 4302), female smoking (n = 4290), parity (n = 4365), infertility diagnosis (n = 4765), type of treatment (n = 4842) and center (n = 4842); some analyses additionally included gestational age (n = 4368) and sex of the child (n = 4833). MAIN RESULTS AND THE ROLE OF CHANCE: No statistically significant associations between blastocyst assessment scores (transfer day, developmental stage, TE, ICM) and preterm birth (8.3%) or birthweight (mean 3461.7 g) were found. The adjusted association between blastocysts with a TE score of C and a TE score of A and length at birth (mean 51.6 cm) were statistically significant (adjusted mean difference 0.4 cm (95% CI: 0.02; 0.77)). Blastocysts transferred with developmental stage score 5 compared to blastocysts transferred with score 3 had a 34% increased probability of being a boy (odds ratio (OR) 1.34 (95% CI: 1.09; 1.64). Further, TE score B blastocysts compared to TE score A blastocysts had a 31% reduced probability of being a boy (OR 0.69 (95% CI: 0.60; 0.80)). LIMITATIONS, REASONS FOR CAUTION: It is possible that some residual confounding remains. WIDER IMPLICATIONS OF THE FINDINGS: Blastocyst selection during ART does not appear to introduce any negative effects on obstetric outcome. Therefore, clinicians and patients can be reassured that the assessment scores of the selected blastocyst will not in themselves pose a risk of preterm birth or affect birthweight and the length at birth.

BACKGROUND: Azoospermic patients have benefited from both epididymal and testicular spermatozoa intracytoplasmic sperm injection (ICSI) treatment and lasers have been used to identify viable, immotile spermatozoa before the procedure. There are limited studies on the safety of laser-assisted selection of immotile spermatozoa. The aim of this study was to investigate the impact of laser-assisted selection of immotile spermatozoa on the obstetric and neonatal outcomes after ICSI. METHODS: A retrospective comparative study was conducted on outcomes of ICSI cycles with testicular spermatozoa from June 2014 to June 2018. Of 132 cycles, 33 were allocated to the test group and oocytes were injected with immotile spermatozoa selected by laser, 99 cycles were allocated as control group. RESULTS: Compared with the control group, no significant differences were found in the pregnancy, implantation, miscarriage and live birth rates in the test group in either fresh or frozen transfer cycles. The cumulative live birth rate in the test group was 69.70%, which was slightly higher than in the control group (60.61%), but this was not statistically different. There were no differences in the average gestational age, premature birth rate, neonatal birth weight, and the malformation rate between the test and control groups (P > 0.05). In addition, the obstetric outcome between the two groups were not different (P > 0.05). CONCLUSIONS: No negative effect on perinatal and neonatal outcomes was seen by using laser-assisted selection of immotile spermatozoa for TESA-ICSI. This study endorses the use of laser-assisted selection of viable spermatozoa for ICSI cycles.

This study aimed to investigate the association of adenomyosis with fertility, pregnancy and neonatal outcomes. An electronic search was conducted using the MEDLINE, PubMed and Cochrane databases up to April 2020. Seventeen observational studies were included. Adenomyosis was significantly associated with a lower clinical pregnancy rate (odds ratio [OR] 0.69; 95% confidence interval [CI] 0.51-0.94) and higher miscarriage rate (OR 2.17; 95% CI 1.25-3.79) after treatment with assisted reproductive technology (ART). The lower clinical pregnancy rate was more significant in the subgroup of patients with short down-regulation protocols. Similar associations were recorded after age adjustment. Adenomyosis was also significantly associated with an increased risk of pre-eclampsia, preterm delivery, Caesarean section, fetal malpresentation, small for gestational age infancy and post-partum haemorrhage, which was confirmed after correction for age and mode of conception. In conclusion, adenomyosis is associated with negative effects on fertility after ART. The potentially protective role of the ultra-long down-regulation protocols needs further evaluation in randomized controlled studies. Adenomyosis is also associated (independently of the mode of conception) with adverse pregnancy and neonatal outcomes. Proper counselling prior to ART and close monitoring of pregnancy in patients with adenomyosis should be recommended.

INTRODUCTION: Pregnant women with systematic lupus erythematosus (SLE) have an increased risk of obstetric complications, such as preeclampsia and premature births. Previous studies have suggested that renal involvement could further increase the risk for adverse obstetric outcomes. Aims: The aim of this study was to compare the obstetric outcomes in a Swedish cohort of patients with SLE with and without lupus nephritis (LN). PATIENTS AND METHODS: The study was conducted as a retrospective observational study on 103 women with SLE, who gave birth at the Karolinska University Hospital between the years 2000-2017. Thirty-five women had previous or active LN and 68 women had non-renal lupus. Data was collected from digital medical records. The outcomes that were analysed included infants born small for gestational age (SGA), premature birth, preeclampsia, SLE- or nephritis flare and caesarean section. RESULTS: Women with LN, both with previous and with renal flare during pregnancy suffered from pre-eclampsia more often compared to women with non-renal lupus (25.7% vs 2.9%, p = 0.001) and this complication was associated with premature birth (p = 0.021) and caesarean section (p = 0.035). CONCLUSIONS: Lupus nephritis is a significant risk factor for adverse obstetric outcomes in women with SLE, including preeclampsia. Those patients could benefit from more frequent antenatal controls and more vigorous follow-up.
