- Abstract
Objective To summarize the publications to date from a large obstetric cohort of nulliparous individuals. Study design We summarized all of the publications from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b). We descriptively summarized the most common outcomes and exposures reported in current publications. Results Fifty-six publications to date are discussed. The most common primary exposures reported are participant baseline characteristics such as body mass index (24%), sociodemographic characteristics (22%), and sleep factors (16%). These exposures were most commonly measured in the first trimester (77%). The most commonly reported primary outcomes were related to adverse pregnancy outcomes (APOs, 51.6%), with 25% using a composite of multiple APOs as the primary outcome. At least 8,000 participants were used in the analyses of over half of the publications. Conclusion The nuMoM2b study has generated a diverse array of publications and conclusions on factors associated with APOs. The publicly available data set from the nuMoM2b study continues to hold potential for considerable advances, new insights, and future research opportunities to optimize pregnancy and pregnancy-related health. Key Points The nuMoM2b pregnancy cohort has generated 56 publications thus far. The main findings of these publications are summarized and categorized in this work. The data and specimens from this cohort are available and can answer many clinical questions. [ABSTRACT FROM AUTHOR]

• To assess if fetal fraction is associated with hypertensive disorders of pregnancy. • Low fetal fraction is associated with risk of developing HDP. • Developing standardized values for fetal fraction may be useful. Cell-free fetal DNA (cffDNA) screening is routinely performed in pregnancy. Abnormal fetal fraction has been associated with adverse pregnancy outcomes, including hypertensive disorders of pregnancy, which are associated with severe maternal and neonatal morbidity and mortality. This study examined whether abnormal fetal fraction, defined in this study as fetal fraction either <6 or >15 on the basis of restricted-cubic-spline-plot within our study population, was associated with HDP in a retrospective sample, as well as whether fetal fraction improves the prediction of hypertensive disorders of pregnancy (HDP). We hypothesized that abnormal fetal fraction would be associated with HDP and that adding fetal fraction to a model would significantly improve its strength to predict HDP. Study Design: This was a retrospective cohort study of 729 patients delivering singleton, non-anomalous pregnancies with conclusive cffDNA screening. The primary outcome was HDP. Logistic regression models tested associations between fetal fraction and HDP. We evaluated the impact of including fetal fraction on the prediction of hypertensive disorders of pregnancy (HDP) by comparing the area under the receiver operating characteristic (ROC) curve (AUC) between predictive models with and without fetal fraction. Among the study sample, there was an HDP rate of 11.5 %. Abnormal fetal fraction was defined as <6 % percentile and >15 %, HDP incidence was significantly higher in patients with fetal fraction <6 % compared to patients with fetal fraction in normal range (fetal fraction 6–15 %) (19.5 % vs 10.7 %, p = 0.006 on post hoc comparison). Model 1 had one predictor (fetal fraction) with an AUC of 0.59, Model 2 had three predictors (BMI, nulliparity, history of HDP) with an AUC of 0.71, and Model 3 had four predictors (BMI, nulliparity, history of HDP, and fetal fraction) with an AUC of 0.73. Models 2 and 3 were not significantly different (p = 0.18). More patients who developed HDP had low fetal fraction and fewer patients who developed HDP had high fetal fraction compared to those patients who did not develop HDP. Based on results from multivariable regression models, we cannot conclude that fetal fraction improves HDP prediction. However, developing standardized values for abnormal fetal fraction may be clinically useful. [ABSTRACT FROM AUTHOR]

Objective Methods Results Conclusion The aim of the present study was to evaluate the obstetric complications associated with isolated fetal congenital heart disease (CHD) by comparing pregnancies with and without this condition.In this retrospective matched comparative study at Siriraj Hospital, Thailand, we included 233 postnatally confirmed fetal CHD cases and 466 unaffected fetuses. Controls were selected at a 2:1 ratio, ensuring that they matched the cases in terms of maternal age, parity, and history of preterm deliveries.Fetal CHD was significantly associated with an increased risk of spontaneous preterm labor (30% vs 9.7%; adjusted odds ratio [aOR] 2.42; 95% confidence interval [CI]: 1.35–4.36; P = 0.003), delivery before 34 gestational weeks (11.6% vs 0.6%; aOR 12.33; 95% CI: 3.32–45.78; P < 0.001), and pre‐eclampsia (11.6% vs 2.8%; aOR 2.19; 95% CI: 1.01–4.76; P = 0.047). Newborns with CHD were significantly more likely to be small for gestational age (10.7% vs 5.2%; aOR 2.09; 95% CI: 1.11–3.94; P = 0.022). Intriguingly, a prenatal diagnosis of CHD was associated with a reduced risk of preterm delivery in affected pregnancies (P = 0.002).Pregnancies affected by isolated fetal CHD demonstrated a higher propensity for several adverse outcomes. These findings underscore the importance of prenatal CHD detection and tailored perinatal care to potentially improve both pregnancy outcomes and neonatal health. [ABSTRACT FROM AUTHOR]

Background Aims Methods Results Conclusion Systemic lupus erythematosus (SLE) affects women, with the onset of disease typically around the childbearing years.This study examines the frequency and risk factors for adverse pregnancy outcomes (APOs) in an Australian cohort, and any disease flares during pregnancy and post partum.Female patients with SLE enrolled in the Australian Lupus Registry and Biobank (ALRB) between January 2007 and June 2019 were studied. Self‐reported pregnancy history, including adverse foetal or maternal outcomes, was collected at the time of enrolment and updated as appropriate. Baseline demographics, clinical parameters, medication exposure and disease activity were collected. Factors associated with APO were examined using univariate and multivariate logistic regression analyses.Pregnancy history was available in 278 patients; 30% were nulliparous. Most pregnancies occurred before the diagnosis of SLE. Patients who had pregnancies after SLE diagnosis had an earlier age of diagnosis, and had fewer pregnancies. The APO rate was 44.3% in the overall cohort, with most presenting as prematurity with or without foetal growth restriction. Women with APO were also diagnosed with SLE at a younger age and had a higher prevalence of anti‐cardiolipin antibodies and hypocomplementemia. Early age of SLE diagnosis was a significant independent risk factor for APO. No increase in disease flare was observed in those who experienced APO during the observation period of ALRB.This study shows a considerable incidence of APO in patients with SLE, emphasising the need for pre‐pregnancy counselling and collaboration between maternal‐foetal medicine specialists and rheumatologists, especially for women diagnosed with SLE at a younger age.

Aim Methods Results Conclusion IgA nephropathy (IgAN) is the most common primary glomerular disease worldwide. Pregnant IgAN patients are more susceptible to adverse pregnancy outcomes (APO). However, the risk factor for APO and its effects on the long‐term renal outcome of pregnant IgAN patients remained unclear.We performed a retrospective observational study covering 2003–2019 that included 44 female IgAN patients with pregnancy history to investigate the risk factor for APO and its impact on clinical outcome in IgAN. Renal function outcome and proteinuria remission were evaluated in pregnant IgAN women with and without APO.In this retrospective and observational study, we found that patients with APO exhibited higher levels of serum creatinine and IgM, and lower haemoglobin levels while other clinical characteristics, pathological characteristics and therapy protocol had no significant difference. We found that anaemia and a higher level of serum IgM were independent risk factors for APO. IgAN pregnant women without APO experienced a higher proportion of proteinuria remission than those with APO, but there is no difference in the renal function outcome.Pregnant IgAN patients with higher risks, including lower haemoglobin levels and higher IgM levels deserve intensive monitoring, and aggressive therapy to reduce proteinuria should be carried out in pregnant IgAN patients with APO.

Background: The incidence of chronic diseases, which are significant contributors to maternal deaths and adverse new-born outcomes, is increasing among women of reproductive age in northern Ghana. This emerging health issue raises serious concerns about the potential exacerbation of adverse birth outcomes in this setting, given that it is one of the regions in the country with a high incidence of such outcomes. We investigated the risks of preterm birth (PTB), low birth weight (LBW), and concurrent PTB and LBW among women with preexisting chronic conditions prior to conception in the Tamale Metropolis of northern Ghana. Methods: A facility-based cross-sectional study was conducted among 420 postpartum women randomly selected from five public health facilities. Information was collected electronically on participants' self-reported experience of chronic conditions, namely, hypertension, diabetes, asthma, heart disease, and sickle cell disease, prior to their most recent pregnancy. Information on gestational age at delivery and birth weight was also collected. Regression modeling was used to quantify the risk of adverse newborn outcomes among women who reported preexisting chronic conditions prior to pregnancy. Results: Chronic diseases affected 31.2% of our sample. Of these, 28.6% had a single chronic condition, while 2.6% had comorbid chronic conditions. The prevalence of PTB was 24.0% (95% CI: 20.2, 28.4), 27.6% (95% CI: 23.5, 32.1) of the newborns were born LBW, and 17.4% (95% CI: 14.0, 21.3) of the pregnancies resulted in both PTB and LBW. Compared with those without chronic conditions, women with chronic conditions prior to conception had a greater risk of PTB (aOR = 6.78, 95% CI: 3.36, 13.68), LBW (aOR = 5.75, 95% CI: 2.96, 11.18), and the co-occurrence of PTB and LBW (aOR = 7.55, 95% CI: 3.32, 17.18). Conclusions: We observed significant rates of PTB, LBW, and the co-occurrence of PTB and LBW among women who were already aware that they had preexisting chronic conditions prior to conception. Our findings highlight a potential gap in the quality of prenatal care provided to these women before delivery. Preconception care may offer an opportunity to address preexisting chronic conditions in women before pregnancy and potentially improve maternal and newborn health outcomes. [ABSTRACT FROM AUTHOR]

Problem: To compare the clinical characteristics and pregnancy outcomes between patients with primary obstetric antiphospholipid syndrome (OAPS) and those with primary non‐criteria obstetric antiphospholipid syndrome (NC‐OAPS), and to identify the risk factors of adverse pregnancy outcomes in both groups. Methods: A retrospective single‐center study was performed in a university hospital of western China, including 141 patients with OAPS and 865 patients with NC‐OAPS. The clinical characteristics, pregnancy complications, and obstetric outcomes of the cohorts were collected from the hospital system and were compared by univariable analysis, and the independent risk factors for adverse pregnancy outcomes (APO) were investigated by logistic regression analysis in these two populations. Results: The OAPS patients had a significantly higher risk for stillbirths compared to the NC‐OAPS patients, while the NC‐OAPS group had a significantly higher risk for preterm birth and overall APO. Double aPL positivity, triple aPL positivity, and gestational hypertension were the independent risk factors for APO in OAPS patients, whereas two of the double aPL positivity subtypes, triple aPL positivity and placenta previa were independent risk factors for APO in NC‐OAPS patients. Conclusion: This study identified different rates in different APOs among OAPS and NC‐OAPS patients. Additionally, this study revealed different risk factors for the development of APO between the two populations. These findings indicated that OAPS and NC‐OAPS are two distinct entities of the same disease, providing new insights into the individualized management for patients with OAPS and NC‐OAPS.

Objective: Although the association of rheumatoid arthritis (RA) to multiple adverse pregnancy outcomes has been well‐studied, the association between serum antibody levels in patients with RA and multiple adverse pregnancy outcomes has not been conclusively demonstrated. Here, we comprehensively assessed the causal impact of RA, serologic antibody‐positive RA (pRA), and serologic antibody‐negative RA (nRA) on the risk of 14 adverse pregnancy outcomes. Methods: The causal impact of RA, pRA, and nRA on 14 adverse pregnancy outcomes was comprehensively assessed using two‐sample Mendelian randomization (MR). Evidence maps based on the results of these two‐sample MR analyses were developed. Data from the UK Biobank and FinnGen databases were utilized for this analysis. The inverse variance weighted (IVW) test was employed as the primary method to estimate causality. "TwoSampleMR" and "MR‐PRESSO" packages were used for data analysis in this study. Results: Using two‐sample MR analysis, we found a significant positive causal association between RA and increased risk of cesarean section (p = 0.003), gestational hypertension (p < 0.001), number of spontaneous miscarriages (p = 0.041), preeclampsia (p = 0.008), premature rupture of membranes (p = 0.030), and preterm (p = 0.010). pRA had a significant positive causal association with an increased risk of cesarean section (p = 0.012), gestational hypertension (p < 0.001), preeclampsia (p = 0.002), and preterm (p = 0.007). A significant positive causal association was also established between nRA and gestational hypertension (p = 0.010), the number of spontaneous miscarriages (p = 0.024), and placental abruption (p = 0.027). In addition, we found a causal association between nRA and birth weight (p = 0.007), but not between RA and pRA and birth weight. Conclusion: The results of this study have important implications for the individualized treatment of RA patients, especially those with positive serum antibody levels. [ABSTRACT FROM AUTHOR]

Background: The maternal lipid profile has been increasingly recognized as a significant factor influencing pregnancy outcomes. Dyslipidemia during pregnancy can have adverse effects on both the mother and the fetus, potentially leading to complications such as preeclampsia, gestational diabetes, preterm delivery, and fetal growth restrictions. Understanding the relationship between maternal lipid levels and adverse pregnancy outcomes is crucial for developing strategies to improve maternal and fetal health. Aim and Objectives : To investigate the relationship between maternal lipid profiles and adverse pregnancy outcomes, emphasizing the potential mechanisms and clinical implications. Materials and Method: This study was a prospective cohort study conducted at the Obstetrics and Gynecology Department of Kakatiya Medical College/Hospital. Warangal, for the duration of one year. The study included 80 pregnant women attending the antenatal clinic at our institute, after getting informed consent from patients and approved by institutional Review board and meeting inclusion and exclusion criterial Results : majority of the patients were form age group of 26-30 Years, followed by 21 - 25 years, majority of the patients had normal BMI followed by Underweight(<18.5). Education showed graduation and above among most of the study participants followed by intermediate, and most of the patients underwent LSCS. study found that elevated levels of total cholesterol and LDL were significantly associated with an increased risk of preeclampsia and gestational diabetes. Higher triglyceride levels were also correlated with an increased likelihood of preterm birth and low birth weight. Conclusion: Assessing the serum lipid profile during pregnancy can serve as an early and cost-effective method to prevent the harmful effects of pregnancy-related hyperlipidemia.

This narrative review aimed to summarize all adverse outcomes of pregnancy in advanced maternal age (AMA) to assess the age of the mother as a potentially crucial risk factor. AMA refers to women older than 35 years. While expectations and the role of women in society have undergone significant changes today, the biology of aging remains unchanged. Various pathologic changes occur in the human body with age, including chronic noncommunicable diseases, as well as notable changes in reproductive organs, that significantly affect fertility. Despite substantial advancements in technology and medicine, pregnancy in AMA remains a formidable challenge. Although there are some advantages to postponing childbirth, they primarily relate to maternal maturity and economic stability. However, regrettably, there are also many adverse aspects of pregnancy at advanced ages. These include complications affecting both the mother and the fetus. Pregnants in AMA were more prone to suffer from gestational diabetes mellitus, preeclampsia, and eclampsia during pregnancy compared to younger women. In addition, miscarriages and ectopic pregnancies were more prevalent. Delivery was more frequently completed via cesarean section, and postpartum complications and maternal mortality were also higher. Unfortunately, there were also complications concerning the fetus, such as chromosomal abnormalities, premature birth, low birth weight, admission to the neonatal intensive care unit, and stillbirth.

Objective: The placenta is a vital organ in the growth and development of fetuses within the uterus. The size of the placenta is positively associated with fetal well-being. The aim of this study was to investigate any potential correlation between placental volume and negative pregnancy outcomes. Materials and Methods: This prospective cohort study was conducted at the department of obstetrics and gynecology, Bhumibol Adulyadej Hospital, Thailand between October 2023 and February 2024. Subjects were singleton pregnant women ever the age of 18 without underlying diseases, namely: diabetes mellitus, hypertension, and autoimmune diseases. Ultrasonography was performed between the gestational ages of 28 and 36 weeks. Placental volume was measured via 3-dimensional ultrasonography and analyzed with maternal and neonatal outcomes. Results: A total of 132 participants were recruited. The mean age of participants was 28.6 years old. The abnormal (AV) and normal (NV) placental volume groups consisted of 14 and 118 cases, respectively. The AV group was older, with higher parity, cesarean delivery rate, and estimated blood loss. This group's newborns had lower Apgar scores rated at 1 and 5 minutes and more neonatal complications than the NV group (with statistical significance). Maternal age exceeding 34 years could also be used to predict abnormal placental volume with sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) at percentages of 57.1, 81.4, 26.7 and 94.1, respectively. Conclusion: There is a correlation between placental volume abnormality and certainly adverse outcomes for newborns. Maternal age greater than 34 is associated with higher occurrence of placental volume abnormality. [ABSTRACT FROM AUTHOR]

This study aims to explore the link between dietary habits and adverse pregnancy outcomes (APOs), including preterm birth (PB), preeclampsia (PE), gestational diabetes mellitus (GDM), fetal growth restriction (FGR), and spontaneous abortion (SA) through two‐sample Mendelian randomization (MR). We accessed publicly available genome‐wide association studies' (GWAS) summary statistics for dietary habits and APOs, respectively. We used five MR methods to synthesize MR estimates across genetic instruments. To ensure the robustness of our results, we assessed heterogeneity, and horizontal pleiotropy, and conducted sensitivity analyses. The primary analysis showed that intake of dried fruit (odds ratio (OR), 0.522; 95% confidence interval (CI): 0.291–0.935) and fresh fruit (OR, 0.487; 95% CI: 0.247–0.960) was related to a decreased risk of PB. While intake of tea (OR, 1.602; 95% CI: 1.069–2.403) and poultry (OR, 6.314; 95% CI: 1.266–31.488) was linked to a heightened risk of PB. Cheese intake was a protective factor against PE (OR, 0.557; 95% CI: 0.337–0.920) and GDM (OR, 0.391; 95% CI: 0.270–0.565). Intake of lamb/mutton had a negative relationship with PE (OR, 0.372; 95%CI: 0.145–0.954), whereas oily fish consumption showed a positive relationship with FGR (OR, 2.005; 95% CI: 1.205–3.339). However, after correction using the false discovery rate (FDR) analysis, only the intake of cheese showed a significant causal relationship with GDM (p < .001). Our study preliminarily found that cheese intake was significantly associated with the lower risk of GDM, while others were suggestively associated with the risk of APOs. Well‐designed prospective studies are still needed to confirm our findings in the future. [ABSTRACT FROM AUTHOR]

Not discounting the important foetal or placental contribution, the endometrium is a key determinant of pregnancy outcomes. Given the inherently linked processes of menstruation, pregnancy and parturition with the endometrium, further understanding of menstruation will help to elucidate the maternal contribution to pregnancy. Endometrial health can be assessed via menstrual history and menstrual fluid, a cyclically shed, easily and non-invasively accessible biological sample that represents the distinct, heterogeneous composition of the endometrial environment. Menstrual fluid has been applied to the study of endometriosis, unexplained infertility and early pregnancy loss; however, it is yet to be examined regarding adverse pregnancy outcomes. These adverse outcomes, including preeclampsia, foetal growth restriction (FGR), spontaneous preterm birth and perinatal death (stillbirth and neonatal death), lay on a spectrum of severity and are often attributed to placental dysfunction. The source of this placental dysfunction is largely unknown and may be due to underlying endometrial abnormalities or endometrial interactions during placentation. We present existing evidence for the endometrial contribution to adverse pregnancy outcomes and propose that a more comprehensive understanding of menstruation can provide insight into the endometrial environment, offering great potential value as a diagnostic tool to assess pregnancy risk. As yet, this concept has hardly been explored. [ABSTRACT FROM AUTHOR]

STILLBIRTH ,SMALL for gestational age ,PREGNANCY outcomes ,FETAL growth retardation ,COUPLES counseling - Abstract
We conducted a systematic review and meta-analysis to examine the relationship between stillbirth and various perinatal outcomes in subsequent pregnancy. PubMed, the Cochrane Library, Embase, Web of Science, and CNKI databases were searched up to July 2023. Cohort studies that reported the association between stillbirth and perinatal outcomes in subsequent pregnancies were included. We conducted this systematic review and meta-analysis in accordance with the PRISMA guidelines. Statistical analysis was performed using R and Stata software. We used random-effects models to pool each outcome of interest. We performed a meta-regression analysis to explore the potential heterogeneity. The certainty (quality) of evidence assessment was performed using the GRADE approach. Nineteen cohort studies were included, involving 4,855,153 participants. From these studies, we identified 28,322 individuals with previous stillbirths who met the eligibility criteria. After adjusting for confounders, evidence of low to moderate certainty indicated that compared with women with previous live births, women with previous stillbirths had higher risks of recurrent stillbirth (odds ratio, 2.68; 95% confidence interval, 2.01–3.56), preterm birth (odds ratio, 3.15; 95% confidence interval, 2.07–4.80), neonatal death (odds ratio, 4.24; 95% confidence interval, 2.65–6.79), small for gestational age/intrauterine growth restriction (odds ratio, 1.3; 95% confidence interval, 1.0–1.8), low birthweight (odds ratio, 3.32; 95% confidence interval, 1.46–7.52), placental abruption (odds ratio, 3.01; 95% confidence interval, 1.01–8.98), instrumental delivery (odds ratio, 2.29; 95% confidence interval, 1.68–3.11), labor induction (odds ratio, 4.09; 95% confidence interval, 1.88–8.88), cesarean delivery (odds ratio, 2.38; 95% confidence interval, 1.20–4.73), elective cesarean delivery (odds ratio, 2.42; 95% confidence interval, 1.82–3.23), and emergency cesarean delivery (odds ratio, 2.35; 95% confidence interval, 1.81–3.06) in subsequent pregnancies, but had a lower rate of spontaneous labor (odds ratio, 0.22; 95% confidence interval, 0.13–0.36). However, there was no association between previous stillbirth and preeclampsia (odds ratio, 1.72; 95% confidence interval, 0.63–4.70) in subsequent pregnancies. Our systematic review and meta-analysis provide a more comprehensive understanding of adverse pregnancy outcomes associated with previous stillbirth. These findings could be used to inform counseling for couples who are considering pregnancy after a previous stillbirth. [Display omitted] [ABSTRACT FROM AUTHOR]

Moral injury is a psychological wound resulting from deep-rooted traumatic experiences that corrode an individual’s sense of humanity, ethical compass, and internal value system. Whether through witnessing a tragic event, inflicting injury on others, or failing to prevent a traumatic injury upon others, moral injury can have severe and detrimental psychological and psychosomatic outcomes that may last a lifetime. Post-traumatic experiences do not have to be a permanent affliction, however. From moral injury can come post-traumatic growth—the recovery from trauma in which personal betterment overshadows moral injury. Moral injury may lead to substantial personal growth, improved capacity and resilience. Based on these observations, it seems that from struggles and darkness, there can be positivity and hope. This review will summarize the current concepts of post-traumatic growth and consider potential mechanisms leading to resilience and recovery through post-traumatic growth. These considerations are gaining more importance in light of a growing number of existential threats, such as violent conflicts, natural disasters and global pandemics.

Abstract Background The incidence of chronic diseases, which are significant contributors to maternal deaths and adverse new-born outcomes, is increasing among women of reproductive age in northern Ghana. This emerging health issue raises serious concerns about the potential exacerbation of adverse birth outcomes in this setting, given that it is one of the regions in the country with a high incidence of such outcomes. We investigated the risks of preterm birth (PTB), low birth weight (LBW), and concurrent PTB and LBW among women with preexisting chronic conditions prior to conception in the Tamale Metropolis of northern Ghana. Methods A facility-based cross-sectional study was conducted among 420 postpartum women randomly selected from five public health facilities. Information was collected electronically on participants’ self-reported experience of chronic conditions, namely, hypertension, diabetes, asthma, heart disease, and sickle cell disease, prior to their most recent pregnancy. Information on gestational age at delivery and birth weight was also collected. Regression modeling was used to quantify the risk of adverse newborn outcomes among women who reported preexisting chronic conditions prior to pregnancy. Results Chronic diseases affected 31.2% of our sample. Of these, 28.6% had a single chronic condition, while 2.6% had comorbid chronic conditions. The prevalence of PTB was 24.0% (95% CI: 20.2, 28.4), 27.6% (95% CI: 23.5, 32.1) of the newborns were born LBW, and 17.4% (95% CI: 14.0, 21.3) of the pregnancies resulted in both PTB and LBW. Compared with those without chronic conditions, women with chronic conditions prior to conception had a greater risk of PTB (aOR = 6.78, 95% CI: 3.36, 13.68), LBW (aOR = 5.75, 95% CI: 2.96, 11.18), and the co-occurrence of PTB and LBW (aOR = 7.55, 95% CI: 3.32, 17.18). Conclusions We observed significant rates of PTB, LBW, and the co-occurrence of PTB and LBW among women who were already aware that they had preexisting chronic conditions prior to conception. Our findings highlight a potential gap in the quality of prenatal care provided to these women before delivery. Preconception care may offer an opportunity to address preexisting chronic conditions in women before pregnancy and potentially improve maternal and newborn health outcomes.

Adverse pregnancy outcomes (APOs) are major risk factors for womens health during pregnancy and even in the years after pregnancy. Due to the heterogeneity of APOs, only few genetic associations have been identified. In this report, we conducted genome-wide association studies (GWASs) of 479 traits that are possibly related to APOs using a large and racially diverse study, Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b). To display extensive results, we developed a web-based tool GnuMoM2b (https://gnumom2b.cumcobgyn.org/) for searching, visualizing, and sharing results from a GWAS of 479 pregnancy traits as well as phenome-wide association studies of more than 17 million single nucleotide polymorphisms. The genetic results from 3 ancestries (Europeans, Africans, and Admixed Americans) and meta-analyses are populated in GnuMoM2b. In conclusion, GnuMoM2b is a valuable resource for extraction of pregnancy-related genetic results and shows the potential to facilitate meaningful discoveries.

Background: Adverse pregnancy outcomes (APOs) are the most important vital statistics used to assess maternal health and child health statistics. They are an indicator of the quality of maternal and child health care services, i.e., antenatal care, intrapartum care, and medical services. Material and Methods: The objective of the study is to analyze the trend, pattern, and prevalence of APOs among women of reproductive age group at the national level over successive NFHS rounds. The current study uses data from the National Family Health Survey (NFHS), conducted during 1992–2021. The study uses geo-spatial mapping techniques through QGIS software and report analysis to arrive at definitive conclusions. Results: The study finds that the incidence of APOs among women of reproductive age (15–49 years) has increased over the years. Twenty states and union territories have APOs that are below the national average. On the other hand, States like Madhya Pradesh, Meghalaya, Sikkim, Goa, Maharashtra, Andhra Pradesh, Karnataka, and Kerala have witnessed their APOs worsening as per NFHS-5 vis-à-vis NFHS-4. The study also finds that apart from the Himalayan belt and the east coast of India, APOs are more prominent in the contiguous regions adjoining these areas. Conclusions: The findings of the study have thrown on very interesting facts. Despite rapid economic development during the intervening period between NFHS-4 and NFHS-5, rising APOs are a testament to the fact that the policymakers in the country need to be more target-oriented and get their acts together.

Abstract Background There is growing evidence of bidirectional associations between rheumatoid arthritis and adverse pregnancy outcomes (APOs) in observational studies, but little is known about the causal direction of these associations. Therefore, we explored the potential causal relationships between rheumatoid arthritis and APOs using a bidirectional two-sample Mendelian randomization (MR) in European and Asian populations. Methods We conducted a bidirectional two-sample Mendelian randomization analysis using available summary statistics from released genome-wide association studies. Summary statistics for instrument–outcome associations were retrieved from two separate databases for rheumatoid arthritis and adverse pregnancy outcomes, respectively. The inverse-variance weighted method was used as the primary MR analysis, and cML-MA-BIC was used as the supplementary analysis. MR-Egger, MR pleiotropy residual sum and outlier (MR-PRESSO), and Cochran Q statistic method were implemented as sensitivity analyses approach to ensure the robustness of the results. Results Our study showed that a higher risk of rheumatoid arthritis in the European population was associated with gestational hypertension (OR: 1.04, 95%CI: 1.02–1.06), pre-eclampsia (OR: 1.06, 95%CI: 1.01–1.11), fetal growth restriction (OR: 1.08, 95%CI: 1.04–1.12), preterm delivery (OR:1.04, 95%CI: 1.01–1.07). Furthermore, we found no evidence that APOs had causal effects on rheumatoid arthritis in the reverse MR analysis. No association between rheumatoid arthritis and APOs was found in East Asian population. There was no heterogeneity or horizontal pleiotropy. Conclusions This MR analysis provides the positive causal association from rheumatoid arthritis to gestational hypertension, pre-eclampsia, fetal growth restriction and preterm delivery genetically. It highlights the importance of more intensive prenatal care and early intervention among pregnant women with rheumatoid arthritis to prevent potential adverse obstetric outcomes.

Abstract Background The management of systemic lupus erythematosus (SLE) during pregnancy remains a challenge currently. Identifying early predictors of adverse pregnancy outcomes in SLE patients can help to develop treatment plan and improve prognosis. The aim of this study is to explore the clinical and laboratory variables in the early pregnancy that can predict adverse neonatal and maternal outcomes, thereby facilitating the grading management of SLE. Methods A retrospective analysis was conducted on 126 pregnant women with SLE who were admitted to Zhongnan Hospital of Wuhan University between January 2017 and December 2022. All enrolled patients were diagnosed (including newly diagnosed and previously diagnosed) during first trimester of pregnancy and their clinical records, laboratory results and pregnancy outcomes were reviewed. The association between the clinical and laboratory characteristics of patients at 12 gestational age and the adverse neonatal (ANOs) as well as maternal outcomes (AMOs) were analyzed. Results A total of 117 live births (92.8%) were recorded in the study. ANOs occurred in 59 (46.8%) cases, including fetal loss in 9 cases (7.1%), preterm birth in 40 cases (31.7%), small for gestational (SGA) in 15 cases (11.9%), and complete heart block in 2 cases (1.5%).

Abstract Background Toxoplasma gondii infection causes adverse pregnancy outcomes by affecting the expression of immunotolerant molecules in decidual immune cells. Galectin-9 (Gal-9) is widely expressed in decidual macrophages (dMφ) and is crucial for maintaining normal pregnancy by interacting with the immunomodulatory protein T-cell immunoglobulin and mucin domain-containing molecule 3 (Tim-3). However, the effects of T. gondii infection on Gal-9 expression in dMφ, and the impact of altered Gal-9 expression levels on the maternal–fetal tolerance function of decidual natural killer (dNK) cells, are still unknown. Methods Pregnancy outcomes of T. gondii-infected C57BL/6 and Lgals9 −/− pregnant mice models were recorded. Expression of Gal-9, c-Jun N-terminal kinase (JNK), phosphorylated JNK (p-JNK), and Forkhead box protein O1 (FOXO1) was detected by western blotting, flow cytometry or immunofluorescence. The binding of FOXO1 to the promoter of Lgals9 was determined by chromatin immunoprecipitation–polymerase chain reaction (ChIP-PCR). The expression of extracellular signal-regulated kinase (ERK), phosphorylated ERK (p-ERK), cAMP-response element binding protein (CREB), phosphorylated CREB (p-CREB), T-box expressed in T cells (T-bet), interleukin 10 (IL-10), and interferon gamma (IFN-γ) in dNK cells was assayed by western blotting. Results Toxoplasma gondii infection increased the expression of p-JNK and FOXO1 in dMφ, resulting in a reduction in Gal-9 due to the elevated binding of FOXO1 with Lgals9 promoter. Downregulation of Gal-9 enhanced the phosphorylation of ERK, inhibited the expression of p-CREB and IL-10, and promoted the expression of T-bet and IFN-γ in dNK cells. In the mice model, knockout of Lgals9 aggravated adverse pregnancy outcomes caused by T. gondii infection during pregnancy. Conclusions Toxoplasma gondii infection suppressed Gal-9 expression in dMφ by activating the JNK/FOXO1 signaling pathway, and reduction of Gal-9 contributed to dysfunction of dNK via Gal-9/Tim-3 interaction. This study provides new insights for the molecular mechanisms of the adverse pregnancy outcomes caused by T. gondii. Graphical Abstract

Abstract Background What kinds of fetal adverse outcomes beyond stillbirth directly correlate to the severity of intrahepatic cholestasis during pregnancy (ICP) remained tangled. Herein, we conducted a retrospective cohort study and a dose-response meta-analysis to speculate the association between the severity of ICP and its adverse outcomes. Methods We retrospectively collected a cohort of ICP patients from electronic records from Guangzhou Women and Children’s Medical Center between Jan 1st, 2018, and Dec 31st, 2022. Also, we searched PubMed, Cochrane, Embase, Scopus, and Web of Science to extract prior studies for meta-analysis. The Kruskal-Wallis test, a one-way or two-way variants analysis (ANOVA), and multi-variant regression are utilized for cohort study. One stage model, restricted cubic spline analysis, and fixed-effect model are applied for dose-response meta-analysis. The data analysis was performed using the R programme. Results Our cohort included 1,289 pregnant individuals, including 385 mild ICP cases, 601 low moderate ICP cases, 282 high moderate ICP cases, and 21 severe ICP cases. The high moderate bile acid levels were correlated to preterm birth [RR = 2.14, 95%CI 1.27 to 3.62), P

Background It is unclear whether women with psoriasis who receive adequate management or achieve better control of their psoriasis before and during pregnancy could eliminate the negative effects. Objectives The objective of this study was to investigate the association between physician visits for psoriasis and adverse pregnancy outcomes. Methods This study used the National Health Insurance database and Birth Certificate Application in Taiwan. This research further categorized the study subjects into mothers with mild/severe psoriasis who visited physicians for psoriasis before delivery, mothers with mild/severe psoriasis who did not visit a physician for psoriasis before delivery, and mothers without psoriasis. Logistic regression was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) for the occurrence of adverse pregnancy outcomes, including maternal and neonatal outcomes. Results 3,339 mothers with severe psoriasis, 41,296 mothers with mild psoriasis, and 2,017,271 mothers without psoriasis were included in this study. The mothers with mild/severe psoriasis demonstrated a significantly higher risk of labor complications and maternal risk factors. After adjusting for confounders, mothers with severe psoriasis who did not visit a physician for psoriasis demonstrated significantly higher odds of labor complications (OR 1.217), maternal risk factors (OR 1.507), having low-birth weight infants (OR 1.236), etc., than mothers without psoriasis. Conclusion This study demonstrated that mothers with psoriasis had a higher risk of adverse pregnancy outcomes. In addition, seeking medical care for psoriasis, particularly for women with severe psoriasis, appeared to exert a protective effect against adverse pregnancy outcomes.

Abstract Background The purpose was to explore the optimal proportion of GWG in Chinese singleton pregnant women according to Chinese specific body mass index (BMI) categories. Methods A retrospective cohort study with 16,977 singleton pregnant women was conducted. Among the including subjects, 2/3 of which were randomly imported into the training set for calculating the optimal GWG ranges using the percentile method, the Odd Ratio (OR) method, and the combined risk curve method. And another third of the subjects were used to evaluate the GWG ranges obtained. The detection rate of adverse outcomes of pregnant women was used to evaluate the applicability of GWG obtained. The range corresponding to the lowest detection rate is the recommended GWG range in this study. Results According to the percentile method, the suitable GWG of pregnant women with underweight, normal weight, overweight or obesity before pregnancy were 12.0 ∼ 17.5 kg, 11.0 ∼ 17.0 kg, and 9.0 ∼ 15.5 kg, respectively. According to the OR method, the suitable GWG range were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, respectively. According to the combined risk curve method, the suitable GWG range were 11.2 ∼ 17.2 kg, 3.6 ∼ 11.5 kg, and − 5.2 ∼ 7.0 kg, respectively. When the GWG for different BMI categories were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, the pregnant women have the lowest detection rate of adverse maternal and infant outcomes. Conclusions The recommended GWG based on this study for underweight, normal, overweight or obese pregnant women were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, respectively.

Our objective was to evaluate whether early pregnancy proactive coping was associated with adverse perinatal outcomes.Study Design: This was a planned secondary analysis of nulliparous pregnant people recruited from a tertiary care center. Participants completed a validated assessment of proactive coping (Proactive Coping Scale) at 8– 20 weeks and were followed longitudinally through delivery. Detailed pregnancy and delivery data were collected by trained research personnel. The primary outcome was a composite of adverse perinatal outcomes including unplanned cesarean delivery, gestational diabetes, and hypertensive disorders of pregnancy. Secondary analyses included individual perinatal composite components and a neonatal morbidity composite measure. Multivariate regression compared adverse perinatal outcomes by Proactive Coping Scale quartile, controlling for a priori confounders.Results: Of the 281 parturients, the median Proactive Coping Scale score was 45.0 (range 25– 55), and 47% experienced an adverse perinatal outcome. After adjusting for confounders, those in the lowest Proactive Coping Scale quartile had 2.2 times higher odds of experiencing an adverse perinatal outcome compared to those in the highest Proactive Coping Scale quartile. There were no differences in odds of the individual composite components or the adverse neonatal outcome.Conclusion: Lower early pregnancy proactive coping scores are associated with significant increase in adverse perinatal outcomes. Interventions that target improving proactive coping may be a novel mechanism for reducing perinatal morbidity.Plain Language Summary: Proactive coping is the process of preparing for a stressor or goal, which has been studied in the context of chronic disease. We sought to understand how proactive coping relates to pregnancy outcomes. Our results indicated that higher proactive coping scores were associated with lower risk of adverse pregnancy outcomes. Therefore, interventions to increase proactive coping may have a role in reducing adverse pregnancy outcomes.Keywords: proactive coping, adverse pregnancy outcomes, cesarean delivery, gestational diabetes, hypertensive disorders of pregnancy

This study evaluated the relationship between oral health status, perceptions, and pregnancy outcomes.Methods: A cross sectional study design was implemented to recruit a convenience sample of women attending Obstetrics and gynecology department in public hospitals in East and capital city of Saudi Arabia. To collect data, a validated self-administered questionnaire in English and Arabic was used. The questionnaire covered background information, perceived oral health status, and dental visits.Results: About 64.4% of the 481 women recruited had dental problems, 49.7% reported deterioration in their oral health during pregnancy, and 17.5% reported adverse pregnancy outcomes. Only 40.7% of pregnant women rated their oral health as good, and only 22% visited a dentist during their pregnancy. Dentists were the most common source of oral health information (44.1%), followed by social media (38.9%). Dental problems during pregnancy were significantly associated with adverse outcomes (P=0.007). Oral health perceptions of pregnant women, not visiting the dentist during pregnancy, and gingival problems were also significantly associated with adverse pregnancy outcomes (P=0.001). Those with fair to poor oral health were twice as likely to experience adverse pregnancy outcome. Those who intended to visit the dentist during their pregnancy but did not do so, as well as those who did not visit the dentist at all were 12 and 9 times more likely to experience adverse pregnancy outcomes respectively.Conclusion: Dental complaints during pregnancy, oral health perceptions, and a lack of dental visits were all linked to increased likelihood of adverse pregnancy outcomes. There is a need for interprofessional collaboration to dispel myths and encourage oral health care and regular dental visits during pregnancy.Keywords: oral health, pregnant women, adverse pregnancy outcomes, preterm, low birth weight

Objectives: This study aimed to evaluate the outcomes of pregnancy in patients with systemic lupus erythematosus (SLE). It focused on identifying clinical and laboratory markers that could predict the common adverse pregnancy outcomes (APOs) after 20 weeks of gestation, namely preeclampsia (PE) and preterm birth (PTB) in them. Methods: Pregnant SLE women who delivered at the study center from 2010 to 2023 were retrospectively analyzed. Categorical variables were evaluated using the chi-square test or Fisher?s exact test, while continuous variables underwent Mann?Whitney U testing. Stepwise regression was used to assess the predictors of pregnancy outcomes. Results: The study enrolled 445 pregnancies in 408 women diagnosed with SLE. Of these, 202 pregnancies (45.4%) resulted in at least one APO. Disease flare-ups, hypertension, and proteinuria during the first trimester were primary predictors of at least one APO and PTB. The most frequently recorded maternal adverse outcome was PE (14.6%), while PTB accounted for 32.6% of fetal adverse outcomes. Multivariate regression analysis identified hypertension, history of PE, associated antiphospholipid syndrome (APS), proteinuria, and low serum C4 in the first trimester as independent risk factors for PE. Regular follow-ups at our center correlated with lower risks of APOs, PE, and PTB. APS also emerged as a risk factor for PTB, whereas the use of hydroxychloroquine (HCQ) during pregnancy seemed to protect against PTB. Conclusion: For pregnancies complicated by SLE, we recommend early pregnancy screening for proteinuria?even in the absence of lupus nephritis?as well as continued use of HCQ and routine prenatal care throughout pregnancy.

Methods: A retrospective analysis was conducted on 126 pregnant women with SLE who were admitted to Zhongnan Hospital of Wuhan University between January 2017 and December 2022. All enrolled patients were diagnosed (including newly diagnosed and previously diagnosed) during first trimester of pregnancy and their clinical records, laboratory results and pregnancy outcomes were reviewed. The association between the clinical and laboratory characteristics of patients at 12 gestational age and the adverse neonatal (ANOs) as well as maternal outcomes (AMOs) were analyzed. Results: A total of 117 live births (92.8%) were recorded in the study. ANOs occurred in 59 (46.8%) cases, including fetal loss in 9 cases (7.1%), preterm birth in 40 cases (31.7%), small for gestational (SGA) in 15 cases (11.9%), and complete heart block in 2 cases (1.5%). Univariate analysis showed that disease activity index (P < 0.0001), lupus nephritis (P = 0.0195), anti-SSB positivity (P = 0.0074) and hypocomplementemia (P = 0.0466) were related to ANOs. However, multivariate analysis showed that only disease activity during early pregnancy was an independent predictor for ANOs (OR = 7.053, 95% CI: 1.882 to 26.291, P = 0.004). In addition, 48 patients experienced AMOs during subsequent trimester, including 24 (19.0%) patients with disease flare and 23 (18.3%) patients with pre-eclampsia. Unplanned pregnancy (P = 0.010), active disease (P = 0.0004), new onset SLE (P = 0.0044) and lupus nephritis (P = 0.0009) were associated with AMOs in univariate analysis, while disease activity was identified as an independent risk factor for AMOs (OR = 2.553, 95% CI: 1.012–6.440, P = 0.047). Conclusion: Active disease in early pregnancy is associated with adverse pregnancy outcomes. For patients with high risk factor for ANOs and AMOs, more intensive treatment and follow-up should be a wise measure. Especially for those who suffer from active disease, they should be fully informed and given the option to terminate or continue their pregnancy. [ABSTRACT FROM AUTHOR]

Objective The objective of this study was to derive profiles of alcohol, tobacco, and recreational drug use during pregnancy for first-time mothers with latent class growth analysis (LCGA) and determine the association of these classes with the risk of adverse pregnancy outcomes (APO). Study Design A secondary analysis of a prospective cohort of Nulliparous Outcomes in Pregnancy: Monitoring Mothers-to-Be was conducted in eight medical centers across the United States from September 30, 2010, to September 23, 2013. Self-reported use of any alcohol, tobacco, or recreational drugs in the 1 month prior to the visit was assessed at up to four visits throughout pregnancy, and APOs included a composite of preterm birth, hypertensive disorder of pregnancy (HDP), small for gestational age (SGA) infant, or stillbirth, and each adverse outcome separately. Results Four latent classes were identified from the LCGA for 10,031 nulliparous pregnant women that were on average 26.9 years old (standard deviation [SD] = 5.7) and mostly non-Hispanic White (59.7%). Classes included consistent tobacco users (N = 517, 5.2%), nonusers (N = 8,945, 89.2%), alcohol users (N = 500, 5.0%), and a combination of alcohol/tobacco/drug users (N = 69, 0.7%). Logistic regression demonstrated that the class of tobacco users was more likely to have an APO (odds ratio [OR] = 1.48, 95% confidence interval [CI] = 1.22–1.81), preterm birth (OR = 1.53, 95% CI = 1.15–2.02), and SGA (OR = 1.79, 95% CI = 1.36–2.35) relative to the class of nonusers. The class of alcohol users was more likely to have HDP (OR = 1.37, 95% CI = 1.11–1.70) and less likely to have preterm birth (OR = 0.59, 95% CI = 0.38–0.90) and SGA (OR = 0.61, 95% CI = 0.40–0.93) compared to nonusers. Conclusion Trajectories of substance use are associated with APOs; thus, interventions to mitigate the use when encountered early in pregnancy are warranted. Key Points Four classes of substance use were identified. Tobacco users were at a higher risk of APO and alcohol users were at higher risk of HDP. Mitigation strategies are warranted to reduce APO.

Background: Toxoplasma gondii infection causes adverse pregnancy outcomes by affecting the expression of immunotolerant molecules in decidual immune cells. Galectin-9 (Gal-9) is widely expressed in decidual macrophages (dMφ) and is crucial for maintaining normal pregnancy by interacting with the immunomodulatory protein T-cell immunoglobulin and mucin domain-containing molecule 3 (Tim-3). However, the effects of T. gondii infection on Gal-9 expression in dMφ, and the impact of altered Gal-9 expression levels on the maternal–fetal tolerance function of decidual natural killer (dNK) cells, are still unknown. Methods: Pregnancy outcomes of T. gondii-infected C57BL/6 and Lgals9−/− pregnant mice models were recorded. Expression of Gal-9, c-Jun N-terminal kinase (JNK), phosphorylated JNK (p-JNK), and Forkhead box protein O1 (FOXO1) was detected by western blotting, flow cytometry or immunofluorescence. The binding of FOXO1 to the promoter of Lgals9 was determined by chromatin immunoprecipitation–polymerase chain reaction (ChIP-PCR). The expression of extracellular signal-regulated kinase (ERK), phosphorylated ERK (p-ERK), cAMP-response element binding protein (CREB), phosphorylated CREB (p-CREB), T-box expressed in T cells (T-bet), interleukin 10 (IL-10), and interferon gamma (IFN-γ) in dNK cells was assayed by western blotting. Results: Toxoplasma gondii infection increased the expression of p-JNK and FOXO1 in dMφ, resulting in a reduction in Gal-9 due to the elevated binding of FOXO1 with Lgals9 promoter. Downregulation of Gal-9 enhanced the phosphorylation of ERK, inhibited the expression of p-CREB and IL-10, and promoted the expression of T-bet and IFN-γ in dNK cells. In the mice model, knockout of Lgals9 aggravated adverse pregnancy outcomes caused by T. gondii infection during pregnancy. Conclusions: Toxoplasma gondii infection suppressed Gal-9 expression in dMφ by activating the JNK/FOXO1 signaling pathway, and reduction of Gal-9 contributed to dysfunction of dNK via Gal-9/Tim-3 interaction. This study provides new insights for the molecular mechanisms of the adverse pregnancy outcomes caused by T. gondii. [ABSTRACT FROM AUTHOR]

Background: What kinds of fetal adverse outcomes beyond stillbirth directly correlate to the severity of intrahepatic cholestasis during pregnancy (ICP) remained tangled. Herein, we conducted a retrospective cohort study and a dose-response meta-analysis to speculate the association between the severity of ICP and its adverse outcomes. Methods: We retrospectively collected a cohort of ICP patients from electronic records from Guangzhou Women and Children's Medical Center between Jan 1st, 2018, and Dec 31st, 2022. Also, we searched PubMed, Cochrane, Embase, Scopus, and Web of Science to extract prior studies for meta-analysis. The Kruskal-Wallis test, a one-way or two-way variants analysis (ANOVA), and multi-variant regression are utilized for cohort study. One stage model, restricted cubic spline analysis, and fixed-effect model are applied for dose-response meta-analysis. The data analysis was performed using the R programme. Results: Our cohort included 1,289 pregnant individuals, including 385 mild ICP cases, 601 low moderate ICP cases, 282 high moderate ICP cases, and 21 severe ICP cases. The high moderate bile acid levels were correlated to preterm birth [RR = 2.14, 95%CI 1.27 to 3.62), P < 0.01], and preterm premature rupture of membranes [RR = 0.34, 95%CI 0.19 to 0.62), P < 0.01]. We added our cases to cases reported by other studies included in the meta-analysis. There were 15,826 patients included in dose-response meta-analysis. The severity of ICP was associated with increased risks of stillbirth, spontaneous preterm birth, iatrogenic preterm birth, preterm birth, admission to neonatal intensive care unit, and meconium-stained fluid (P < 0.05). Conclusions: Our study shows the correlation between the severity of ICP and the ascending risks of stillbirth, preterm birth, and meconium-stained fluid, providing new threshold TBA levels.

The aim of this study was to explore gestational weight gain (GWG) trajectories and their associations with adverse pregnancy outcomes. A retrospective cohort study including 11,064 women with gestational diabetes mellitus (GDM) was conducted between 2015 and 2019 in China. The latent class trajectory model was used to identify GWG trajectories, and logistic regression was performed to examine odds ratio (OR) of pregnancy outcomes. Three trajectories of GWG were identified in these 11,604 women with GDM. Trajectory 1: 64.02% of women had sustained moderate GWG throughout pregnancy; Trajectory 2: 17.75% of women showed a high initial GWG but followed by a low GWG from the third trimester until delivery; Trajectory 3: 18.23% had low initial GWG but followed by drastic GWG from the second trimester until delivery. Compared with pregnant women with Trajectory 1, women with Trajectory 2 had a higher risk of large for gestational age (adjusted odds ratio [AOR]: 1.29, 95% confidence interval [CI]: 1.12–1.48) but at a lower risk of having hypertensive disorders of pregnancy (AOR: 0.76, 95% CI: 0.57–0.96). Women in Trajectory 3 were more likely to develop small for gestational age (AOR: 2.12, 95% CI: 1.62–2.78), low birthweight (AOR: 1.49, 95% CI: 1.07–2.08), preterm birth (AOR: 1.28, 95% CI: 1.05–1.63), caesarean section (AOR: 1.26, 95% CI: 1.112–1.42) and hypertensive disorders of pregnancy (AOR: 2.24, 95% CI: 1.82–2.76). The association of GWG trajectory with adverse pregnancy outcomes differs across prepregnancy body mass index and GWG categories. Women with a slow initial GWG but followed by drastic GWG had higher risks of adverse pregnancy outcomes. Early clinical recognition of poor GWG trajectory will contribute to early intervention in high‐risk groups to minimise adverse outcomes. Key messages: Gestational weight gain (GWG) is a controllable factor and is strongly associated with maternal and fetal outcomes, especially among gestational diabetes mellitus.The same total GWG may present different trajectories, and the trajectory patterns of GWG vary with women in different body mass index categories.Clarifying the relationship between GWG trajectory and adverse pregnancy outcomes may contribute to the clear goal of lifestyle interventions based on weight control.Early recognition of an unhealthy GWG trajectory may contribute to early intervention in high‐risk groups to minimise adverse outcomes.

Background: Adverse pregnancy outcomes (APOs) are the most important vital statistics used to assess maternal health and child health statistics. They are an indicator of the quality of maternal and child health care services, i.e., antenatal care, intrapartum care, and medical services. Material and Methods: The objective of the study is to analyze the trend, pattern, and prevalence of APOs among women of reproductive age group at the national level over successive NFHS rounds. The current study uses data from the National Family Health Survey (NFHS), conducted during 1992-2021. The study uses geo-spatial mapping techniques through QGIS software and report analysis to arrive at definitive conclusions. Results: The study finds that the incidence of APOs among women of reproductive age (15-49 years) has increased over the years. Twenty states and union territories have APOs that are below the national average. On the other hand, States like Madhya Pradesh, Meghalaya, Sikkim, Goa, Maharashtra, Andhra Pradesh, Karnataka, and Kerala have witnessed their APOs worsening as per NFHS-5 vis-à-vis NFHS-4. The study also finds that apart from the Himalayan belt and the east coast of India, APOs are more prominent in the contiguous regions adjoining these areas. Conclusions: The findings of the study have thrown on very interesting facts. Despite rapid economic development during the intervening period between NFHS-4 and NFHS-5, rising APOs are a testament to the fact that the policymakers in the country need to be more target-oriented and get their acts together.

Objective: To explore the relationships between gestational hepatitis B virus (HBV) infection, antiviral therapy, and pregnancy outcomes. Methods: We retrospectively selected hepatitis B surface antigen (HBsAg)‐positive pregnant women hospitalized for delivery at Fujian Medical University Affiliated Hospital from October 1, 2016 to October 1, 2020. The control group included randomly selected healthy pregnant women hospitalized for delivery during the same time. Results: Overall, 1115 participants were enrolled and grouped into control (n = 380) and HBsAg‐positive groups (n = 735), which were further divided into groups I (n = 407; low viral load), II (n = 207; high viral load without antiviral therapy), and III (n = 121; high viral load with antiviral therapy). Pregnant women with HBV were positively correlated with the incidence of intrahepatic cholestasis of pregnancy (ICP) (adjusted odds ratio [aOR] 5.1, 95% confidence interval [CI] 2.62–9.92, P < 0.001), neonatal jaundice (aOR 10.56, 95% CI 4.49–24.83, P < 0.001), and neonatal asphyxia (aOR 5.03, 95% CI 1.46–17.27, P = 0.01). Aspartate aminotransferase (AST) greater than the upper limit of normal (ULN) was an independent risk factor for increased ICP incidence (aOR 3.49, 95% CI 1.26–9.67, P = 0.019). Antiviral therapy considerably reduced HBV DNA and improved liver function. High viral load and antiviral therapy did not correlate significantly with adverse pregnancy outcomes (P < 0.05). Conclusion: Pregnant women with HBV have significantly elevated incidence of ICP, neonatal jaundice, and neonatal asphyxia not significantly correlated with viral load. AST greater than ULN independently increases the risk of ICP. Antiviral therapy effectively reduces viral replication and improves liver function without increasing the risk of adverse outcomes. Synopsis: Pregnant women with HBV have a significantly elevated ICP, neonatal jaundice, and neonatal asphyxia incidence without a significant correlation with viral load and antiviral therapy.

Objective: There is a high prevalence and incidence rate of asymptomatic sexually transmitted infections (STIs) during pregnancy in adolescent girls and young women in Africa. The association between STIs and pregnancy outcomes in a hyperepidemic HIV setting has not been well described. Methods: Pregnant women, HIV‐1 negative and <28 weeks' gestation at three primary health clinics in KwaZulu‐Natal, South Africa were enrolled from February 2017 to March 2018. Vaginal swabs collected at the first and later antenatal visits were stored and retrospectively tested for HSV‐2, Trichomonas vaginalis, Chlamydia trachomatis and Neisseria gonorrhoeae at the end of the study. The association between STIs detected at first and later antenatal visits and pregnancy outcome was assessed using multivariable logistic regression models adjusted for maternal age and treatment received for symptomatic STIs. Results: Testing positive Mycoplasma genitalium at the first antenatal visit was significantly associated with low birth weight (odds ratio [OR] 5.22; 95% confidence interval [CI]: 1.10–15.98). Testing positive for T. vaginalis at the repeat visit was significantly associated with preterm births (OR 2.37; 95% CI: 1.11–5.03), low birth weight (OR 2.56; 1.16–5.63) and a composite adverse pregnancy outcome (OR 2.11; 95% CI: 1.09–4.08). Testing positive for HSV‐2 at the repeat visit was also likely associated with experiencing a preterm birth or any adverse pregnancy outcome (OR 3.39; 95% CI: 0.86–13.3) (P = 0.096). Conclusions: Among predominantly asymptomatic STIs, M. genitalium detected at baseline visit was significantly associated with low birth weight, while T. vaginalis detected at the repeat visit in later pregnancy was significantly associated with preterm birth. Further research is warranted to study the impact of etiological testing of STIs at more than one antenatal visit and empirical treatment on pregnancy outcomes. Synopsis: In a retrospective cohort study, etiological testing revealed a strong association between Mycoplasma genitalium and Trichomonas vaginalis with low birth weight and preterm birth, respectively.

Patients with rheumatic diseases frequently operate with incomplete or incorrect information while planning for and experiencing pregnancy, often due to variability in provider care and knowledge. Risk assessment at each stage of pregnancy—pre-conception, during pregnancy, and postpartum—is focused on reducing maternal and neonatal complications. This review aims to compile updated, evidence-based guidance on how to minimize risk factors contributing to adverse pregnancy outcomes (APOs). Mitigation of known causes of infertility, appropriate testing and monitoring, achieving low disease activity on pregnancy-safe disease-modifying antirheumatic drugs (DMARDs) prior to conception, controlling hypertension (a frequent comorbidity among patients with certain rheumatic diseases), and the use of appropriate adjunctive medications (such as low-dose aspirin when preeclampsia risk is high) can optimize fertility and prevent adverse maternal and neonatal outcomes.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that predominantly affects women of childbearing age. Pregnancy in SLE patients poses unique challenges due to the potential impact on maternal and fetal outcomes. We provide an overview of the management of SLE during pregnancy, including preconception risk stratification and counseling, treatment, and disease activity monitoring. These assessments are critical to minimize maternal and fetal adverse events in pregnant patients with SLE. Disease flares, preeclampsia, antiphospholipid syndrome complications, and maternal mortality are the major risks for a woman with SLE during gestation. Timely treatment of SLE relapse, differentiation of preeclampsia from lupus nephritis, and tailored management for antiphospholipid syndrome are essential for a successful pregnancy. Fetal outcomes include neonatal lupus (NL), preterm birth, cesarean delivery, fetal growth restriction (FGR), and small-for-gestational-age (SGA) infants. We focused on NL, linked to maternal anti-Ro/SS-A and anti-La/SS-B antibodies, which can lead to various manifestations, particularly cardiac abnormalities, in newborns. While there is a common consensus regarding the preventive effect of hydroxychloroquine, the role of echocardiographic monitoring and fluorinated steroid treatment is still debated. Finally, close postpartum monitoring and counseling for subsequent pregnancies are crucial aspects of care. [ABSTRACT FROM AUTHOR]

Background We evaluated associations between antepartum weight change and adverse pregnancy outcomes and between antiretroviral therapy (ART) regimens and week 50 postpartum body mass index in IMPAACT 2010. Methods Women with human immunodeficiency virus (HIV)-1 in 9 countries were randomized 1:1:1 at 14–28 weeks' gestational age (GA) to start dolutegravir (DTG) + emtricitabine (FTC)/tenofovir alafenamide fumarate (TAF) versus DTG + FTC/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF. Insufficient antepartum weight gain was defined using Institute of Medicine guidelines. Cox-proportional hazards regression models were used to evaluate the association between antepartum weight change and adverse pregnancy outcomes: stillbirth (≥20 weeks' GA), preterm delivery (<37 weeks' GA), small size for GA (<10th percentile), and a composite of these endpoints. Results A total of 643 participants were randomized: 217 to the DTG + FTC/TAF, 215 to the DTG + FTC/TDF, and 211 to the EFV/FTC/TDF arm. Baseline medians were as follows: GA, 21.9 weeks; HIV RNA, 903 copies/mL; and CD4 cell count, 466/μL. Insufficient weight gain was least frequent with DTG + FTC/TAF (15.0%) versus DTG + FTC/TDF (23.6%) and EFV/FTC/TDF (30.4%). Women in the DTG + FTC/TAF arm had the lowest rate of composite adverse pregnancy outcome. Low antepartum weight gain was associated with higher hazard of composite adverse pregnancy outcome (hazard ratio, 1.44 [95% confidence interval, 1.04–2.00]) and small size for GA (1.48 [.99–2.22]). More women in the DTG + FTC/TAF arm had a body mass index ≥25 (calculated as weight in kilograms divided by height in meters squared) at 50 weeks postpartum (54.7%) versus the DTG + FTC/TDF (45.2%) and EFV/FTC/TDF (34.2%) arms. Conclusions Antepartum weight gain on DTG regimens was protective against adverse pregnancy outcomes typically associated with insufficient weight gain, supportive of guidelines recommending DTG-based ART for women starting ART during pregnancy. Interventions to mitigate postpartum weight gain are needed. [ABSTRACT FROM AUTHOR]

Background: A retrospective cohort study was conducted to collect the data of pregnant women who received hospital delivery in Hangzhou Women's Hospital from January 2018 to December 2020, and who participated in the second trimester (15–20+6 weeks) of free beta human chorionic gonadotropin (free β-hCG). And the study was conducted to explore the relationship between maternal serum free β-hCG and adverse pregnancy outcomes (APO). Methods: We retrospectively analyzed the clinical data of 1,978 women in the elevated maternal serum free β-hCG group (free β-hCG ≥ 2.50 multiples of the median, MoM) and 20,767 women in the normal group (0.25 MoM ≤ free β-hCG < 2.50 MoM) from a total of 22,745 singleton pregnancies, and modified Poisson regression analysis was used to calculate risk ratios (RRs) and 95% confidence intervals (CI) of the two groups. Results: The gravidity and parity in the elevated free β-hCG group were lower, and the differences between the groups were statistically significant (all, P < 0.05). The risks of polyhydramnios, preeclampsia, and hyperlipidemia, were increased in women with elevated free β-hCG levels (RRs: 1.996, 95% CI: 1.322–3.014; 1.469, 95% CI: 1.130–1.911 and 1.257, 95% CI: 1.029–1.535, respectively, all P < 0.05), intrauterine growth restriction (IUGR) and female infants were also likely to happen (RRs = 1.641, 95% CI: 1.103–2.443 and 1.101, 95% CI: 1.011–1.198, both P < 0.05). Additionally, there was an association between elevated AFP and free β-hCG levels in second-trimester (RR = 1.211, 95% CI: 1.121–1.307, P < 0.001). Conclusions: APOs, such as polyhydramnios, preeclampsia, and hyperlipidemia, were increased risks of elevated free β-hCG levels, IUGR and female infants were also likely to happen. Furthermore, there was an association between elevated AFP levels and elevated free β-hCG levels in second-trimester. We recommend prenatal monitoring according to the elevated maternal serum free β-hCG level and the occurrence of APO. [ABSTRACT FROM AUTHOR]

Objective: To examine the association with adverse pregnancy outcomes of: (1) American College of Cardiology/American Heart Association blood pressure (BP) thresholds, and (2) visit‐to‐visit BP variability (BPV), adjusted for BP level. Design: An observational study. Setting: Analysis of data from the population‐based UK Southampton Women's Survey (SWS). Population or sample: 3003 SWS participants. Methods: Generalised estimating equations were used to estimate crude and adjusted relative risks (RRs) of adverse pregnancy outcomes by BP thresholds, and by BPV (as standard deviation [SD], average real variability [ARV] and variability independent of the mean [VIM]). Likelihood ratios (LRs) were calculated to evaluate diagnostic test properties, for BP at or above a threshold, compared with those below. Main outcome measures: Gestational hypertension, severe hypertension, pre‐eclampsia, preterm birth (PTB), small‐for‐gestational‐age (SGA) infants, neonatal intensive care unit (NICU) admission. Results: A median of 11 BP measurements were included per participant. For BP at ≥20 weeks' gestation, higher BP was associated with more adverse pregnancy outcomes; however, only BP <140/90 mmHg was a good rule‐out test (negative LR <0.20) for pre‐eclampsia and BP ≥140/90 mmHg a good rule‐in test (positive LR >8.00) for the condition. BP ≥160/110 mmHg could rule‐in PTB, SGA infants and NICU admission (positive LR >5.0). Higher BPV (by SD, ARV, or VIM) was associated with gestational hypertension, severe hypertension, pre‐eclampsia, PTB, SGA and NICU admission (adjusted RRs 1.05–1.39). Conclusions: While our findings do not support lowering the BP threshold for pregnancy hypertension, they suggest BPV could be useful to identify elevated risk of adverse outcomes.

Introduction: Maternal blood pressure (BP) is a critical cardiovascular marker with profound implications for maternal and fetal well-being, particularly in the detection of hypertensive disorders during pregnancy. Although conventional clinic-based BP (CBP) measurements have traditionvally been used, monitoring 24-hour ambulatory BP (ABP) has emerged as a more reliable method for assessing BP levels and diagnosing conditions such as gestational hypertension and preeclampsia/eclampsia. This study aimed to assess the feasibility and acceptability of 24-hour ABP monitoring in pregnant women and report on various ABP parameters, including ambulatory blood pressure variability (ABPV). Method: A prospective cross-sectional study design was employed, involving 55 multipara pregnant women with and without prior adverse pregnancy outcomes (APOs). The participants underwent baseline assessments, including anthropometrics, resting CBP measurements, and the placement of ABP and actigraphy devices. Following a 24-hour period with these devices, participants shared their experiences to gauge device acceptability. Pregnancy outcomes were collected postpartum. Results: Twenty-four-hour ABP monitoring before 20 weeks of gestation is feasible for women with and without prior APOs. Although some inconvenience was noted, the majority of participants wore the ABP monitoring device for the entire 24-hour period. Pregnant women who later experienced APOs exhibited higher 24-hour ABP and ABPV values in the early stages of pregnancy. Conclusion: The study highlights the potential benefits of 24-hour ABP monitoring as a valuable tool in prenatal care, emphasizing the need for further research in this area. [ABSTRACT FROM AUTHOR]

Introduction: There are limited and conflicting data regarding the impact of hepatitis C in pregnancy on adverse birth outcomes. Methods: Using the Surveillance for Emerging Threats to Pregnant People and Infants Network (SET-NET), a large surveillance cohort, we describe birth outcomes among a cohort of people with HCV in pregnancy in total and by reported substance use. Results: Among 1418 infants, 89% were born to people with reported substance use during pregnancy. The proportion born preterm was 20%, 13% were small-for-gestational age and 34% of term infants required intensive care. Conclusions: Assessments of recent changes to recommendations for HCV screening in pregnancy should evaluate the impact on maternal access to care for both HCV treatment as well as comorbidities such as substance use disorder which may contribute to adverse birth outcomes. Significance: Incidence of hepatitis C in pregnancy is increasing. Prematurity, small-for-gestational age, and intensive care unit admission were common among this surveillance cohort of infants born to people with hepatitis C in pregnancy with high frequency of substance use. Assessments of recent changes to recommendations for HCV screening in pregnancy should evaluate the impact on maternal access to care for both HCV treatment as well as comorbidities such as substance use disorder which may contribute to adverse birth outcomes.

Background: To determine the association between lipid metabolism and intrahepatic cholestasis of pregnancy (ICP), and explore the value of maternal alanine aminotransferase/aspartate aminotransferase (ALT/AST) and high-density lipoprotein (HDL) in predicting adverse neonatal outcomes in women with ICP. Methods: A total of 147 pregnant women with ICP admitted to The Fourth Hospital of Shijiazhuang and 120 normal pregnant women in the same period were selected in this study. The Mann-Whitney U test and Chi-square tests were used to compare the differences in clinical data. Multivariate logistic regression was used to analyze the relationship between ALT/AST and the occurrence of adverse pregnancy outcomes in patients with ICP. The combined predictive value of ALT/AST and HDL was determined by receiver operating characteristic (ROC) curve analysis. Results: Among 147 women with ICP, 122 women had total bile acid (TBA) levels of 10–39.9 µmol/L, and 25 had TBA ≥ 40 µmol/L. There was significantly lower gestational age in patients with severe ICP than in those with mild and control groups (all p < 0.05), and the weight of newborns in the maternal ICP group was significantly lower than in the control group (p < 0.05). Increasing TBA levels was associated with higher AST, ALT, ALT/AST, and lower HDL level (all p < 0.05). Meanwhile, higher levels of ALT/AST was positively associated with neonatal hyperbilirubinemia [adjusted odds ratio (AOR) = 4.019, 95% CI [1.757–9.194, p = 0.001] and cardiac injury [AOR = 3.500, 95% CI [1.535–7.987], p = 0.003]. HDL was a significant protective factor for neonatal hyperbilirubinemia and cardiac injury [AOR = 0.315, 95% CI [0.126–0.788], p = 0.014; AOR = 0.134 (0.039–0.461), p = 0.001]. The area under the ROC curve (AUC) for prediction of neonatal hyperbilirubinemia by ALT/AST combined with HDL was 0.668 [95% CI [56.3–77.3%], p = 0.002], and the sensitivity and specificity were 47.1% and 84.0%, respectively. To predict neonatal cardiac injury, the AUC value was 0.668 [95% CI [56.4–77.1%], p = 0.002], with sensitivity and specificity were 41.2% and 87.1%, respectively. Conclusions: The levels of higher ALT/AST and lower HDL were significantly associated with the risk of ICP-related adverse neonatal outcomes. Moreover, ALT/AST combined with HDL has moderate clinical value in predicting the adverse outcomes of neonatal hyperbilirubinemia and cardiac injury. [ABSTRACT FROM AUTHOR]

Background: The purpose was to explore the optimal proportion of GWG in Chinese singleton pregnant women according to Chinese specific body mass index (BMI) categories. Methods: A retrospective cohort study with 16,977 singleton pregnant women was conducted. Among the including subjects, 2/3 of which were randomly imported into the training set for calculating the optimal GWG ranges using the percentile method, the Odd Ratio (OR) method, and the combined risk curve method. And another third of the subjects were used to evaluate the GWG ranges obtained. The detection rate of adverse outcomes of pregnant women was used to evaluate the applicability of GWG obtained. The range corresponding to the lowest detection rate is the recommended GWG range in this study. Results: According to the percentile method, the suitable GWG of pregnant women with underweight, normal weight, overweight or obesity before pregnancy were 12.0 ∼ 17.5 kg, 11.0 ∼ 17.0 kg, and 9.0 ∼ 15.5 kg, respectively. According to the OR method, the suitable GWG range were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, respectively. According to the combined risk curve method, the suitable GWG range were 11.2 ∼ 17.2 kg, 3.6 ∼ 11.5 kg, and − 5.2 ∼ 7.0 kg, respectively. When the GWG for different BMI categories were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, the pregnant women have the lowest detection rate of adverse maternal and infant outcomes. Conclusions: The recommended GWG based on this study for underweight, normal, overweight or obese pregnant women were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, respectively. [ABSTRACT FROM AUTHOR]

PREGNANCY outcomes , *PRENATAL diagnosis , *PREGNANCY tests , *SMALL for gestational age , *CELL-free DNA - Abstract
(1) Background: Non-invasive prenatal testing (NIPT) is a screening test for fetal aneuploidy using cell-free fetal DNA. The fetal fragments (FF) of cell-free DNA (cfDNA) are derived from apoptotic trophoblast of the placenta. The level of fetal cfDNA is known to be influenced by gestational age, multiple pregnancies, maternal weight, and height. (2) Methods: This study is a single-center retrospective observational study which examines the relationship between the fetal fraction (FF) of cell-free DNA in non-invasive prenatal testing (NIPT) and adverse pregnancy outcomes in singleton pregnancies. A total of 1393 samples were collected between 10 weeks and 6 days, and 25 weeks and 3 days of gestation. (3) Results: Hypertensive disease of pregnancy (HDP) occurred more frequently in the low FF group than the normal FF group (5.17% vs. 1.91%, p = 0.001). Although the rates of small for gestational age (SGA) and placental abruption did not significantly differ between groups, the composite outcome was significantly higher in the low FF group (7.76% vs. 3.64%, p = 0.002). Furthermore, women who later experienced complications such as HDP or gestational diabetes mellitus (GDM) had significantly lower plasma FF levels compared to those without complications (p < 0.001). After adjustments, the low FF group exhibited a significantly higher likelihood of placental compromise (adjusted odds ratio: 1.946). (4) Conclusions: Low FF in NIPT during the first and early second trimesters is associated with adverse pregnancy outcomes, particularly HDP, suggesting its potential as a predictive marker for such outcomes.

Purpose: This study aimed to investigate the association between simple markers in fetal abdominal plane, intra-abdominal umbilical venous diameter (DIUV) and abdominal circumference (AC) discordance at 15–20 weeks' gestation, and adverse pregnancy outcomes in monochorionic diamniotic (MCDA) twins. Methods: We performed a retrospective analysis of MCDA twins with two live fetuses examined at 15–20 weeks from Jun 2020 to Dec 2021 at Beijing Obstetrics and Gynecology Hospital. Measurement of fetal AC and DIUV was performed according to standard protocols. Twin pregnancies with major fetal structural anomalies, chromosomal abnormalities, miscarriage, and twin reversed arterial perfusion sequence were excluded. DIUV and AC discordance in MCDA twins with an adverse pregnancy outcome was compared with a normal pregnancy outcome. Furthermore, the performance of DIUV and AC discordance in predicting adverse pregnancy outcomes in MCDA twins was assessed. Results: A total of 105 women with MCDA twin pregnancies were enrolled, contributing 179 visits. Adverse pregnancy outcomes occurred in 33.3% (35/105) of cases in our study. The intra-observer and inter-observer intraclass correlation coefficient (ICC) of both AC and DIUV were very good or excellent. There was no statistical difference in AC and DIUV discordance (%) between 15–16, 17–18, and 19–20 weeks (χ2 = 3.928, P = 0.140; χ2 = 2.840, P = 0.242). Both AC and DIUV discordance were greater in twins with adverse pregnancy outcomes than that in twins with normal pregnancy outcome at each pregnancy periods. Both AC discordance (OR 1.2, 95% CI 1.1–1.3) and DIUV discordance (OR 1.2, 95% CI 1.1–1.2) were associated with adverse pregnancy outcomes. The AUC for predicting adverse pregnancy outcomes by AC discordance was 0.75 (95% CI 0.68–0.83), with a sensitivity of 58.7% (95% CI 51.9–64.5) and a specificity of 86.2% (95% CI 81.7–88.4). The AUC for predicting adverse pregnancy outcomes by DIUV was 0.78 (95% CI 0.70–0.86), with sensitivity and specificity of 65.1% (95% CI 58.1–70.3) and 86.2% (95% CI 81.7–88.4), respectively. Conclusions: The AC discordance and DIUV discordance could predict adverse pregnancy outcomes in MCDA twins. When these simple markers occurred, intensive surveillance was recommended.
