Variability in COVID-19 Symptom Presentation During Pregnancy and its Impact on Maternal and Infant Outcomes Across the Pandemic

With the dominance of different SARS-CoV-2 variants, the severity of COVID-19 has evolved. We aimed to investigate the difference in symptom prevalence and the association between symptoms and adverse pregnancy outcomes during the dominance of Wild-type/Alpha, Delta, and Omicron. COVID-19 related symptom prevalence, maternal and specific neonatal outcomes of 5431 pregnant women registered in this prospective study were compared considering the dominant virus variant. Logistic regression models analyzed the association between specific symptoms and intensive care unit (ICU) admission or preterm birth. Infection with the Delta variant led to an increase in the symptom burden compared to the Wild-type/Alpha variant and the highest risk for respiratory tract symptoms, feeling of sickness, headache, and dizziness/drowsiness. An infection with the Omicron variant was associated with the lowest risk of dyspnea and changes in smell/taste but the highest risk for nasal obstruction, expectoration, headaches, myalgia, and fatigue compared to the Wild-type/Alpha and Delta variant dominant periods. With the progression of the Wild-type/Alpha to the Delta variant neonatal outcomes worsened. Dyspnea and fever were strong predictors for maternal ICU admission and preterm birth independent of vaccination status or trimester of infection onset. The symptom burden increased during the Delta period and was associated with worse pregnancy outcomes than in the Wild-type/Alpha area. During the Omicron dominance there still was a high prevalence of less severe symptoms. Dyspnea and fever can predict a severe maternal illness.

Impact Of Preeclampsia On Maternal And Neonatal Health: A Retrospective Cohort Study

Objective — Understanding the relationship between maternal characteristics of patients with preeclampsia (PE) and disease progression, as well as the impact on neonatal and parturient outcomes, is critical to the development of effective interventions to improve maternal and fetal outcomes in preeclamptic patients. Material and Methods — This retrospective study analyzed 94 patients with PE and focused on the relationship between maternal characteristics and laboratory findings, as well as on the impact on neonatal and parturient outcomes. Comprehensive laboratory and ultrasound examinations were performed, with primary outcomes classified into antenatal, perinatal and postpartum periods, and secondary outcomes focusing on neonatal health. Results — Patients with PE requiring maternal intensive care unit (ICU) admission had higher median serum creatinine, AST, and ALT levels vs. non-ICU patients. Patients who required postpartum medications to control blood pressure had elevated median values of urea concentration, systolic blood pressure, and diastolic blood pressure at diagnosis. A notable difference in ALT values was observed when primary cesarean section was indicated (p=0.036). Subgroup analysis revealed higher median birth weight in the Proteinuria 1+ subgroup vs. the Proteinuria 4+ subgroup (p=0.002). Patients with negative proteinuria levels demonstrated less need for neonatal intensive care unit (NICU) compared with higher proteinuria levels. In addition, a higher need for postpartum medical therapy was noted in patients of Proteinuria 4+ subgroup (74.2%). Conclusion — This study emphasizes the important role of laboratory data and blood pressure monitoring, advocating targeted interventions and clinical approaches to improve maternal postpartum outcomes (need for ICU). It also highlights the utility of urine dipstick testing for effective decision-making in the care of mothers and newborns in the postpartum period.

COVID‐19 as a risk factor for hypertensive disorders of pregnancy: A retrospective cohort study

AbstractObjectiveThe aim of this study was to assess whether coronavirus disease 2019 (COVID‐19) infection during pregnancy is a risk factor for hypertensive disorders of pregnancy.MethodsA retrospective evaluation was conducted on obstetric patients who gave birth between March 2020 and December 2021 at an academic urban referral center. The patients were categorized as COVID‐19‐positive or COVID‐19‐negative during pregnancy. The primary outcome was the development of a hypertensive disorder of pregnancy. Secondary outcomes included preterm delivery, mode of delivery, maternal death, maternal intensive care unit (ICU) admission, neonatal ICU admission, intrauterine fetal demise/stillbirth, fetal growth restriction and prolonged hospital stay. χ2 tests, Fisher's exact tests, Student's two‐sample tests and multiple logistic regressions were used to evaluate the association between COVID‐19 status and outcomes.ResultsOf 2760 reviewed charts, 2426 (87.9%) met the inclusion criteria. Of 2426 patients, 203 were COVID‐positive and 2223 were COVID‐negative. There were no significant demographic differences between the two groups. After adjusting for confounding effects, COVID‐19 was determined to be a risk factor for combined hypertensive disorders of pregnancy (odds ratio [OR] 1.93, 95% confidence interval [CI]: 1.39–2.66) and pre‐eclampsia specifically (OR 2.01, 95% CI 1.38–2.88). COVID‐19 infection during pregnancy was weakly associated with an increased risk of caesarean delivery (p = 0.046) on univariate analysis but not on multivariate analysis, whereas it was associated with an increased risk of maternal ICU admission (p = 0.003), and prolonged hospital stay (p < 0.001) both before and after multivariate analysis.ConclusionThis study suggests that COVID‐19 infection during pregnancy is a risk factor for pre‐eclampsia. The study was unable to draw conclusions about more severe hypertensive conditions of pregnancy hemolysis, elevated liver enzymes and low platelet count; Eclampsia. COVID‐19 was determined to be a risk factor for prolonged hospital stay and maternal ICU admission, but there was no significant correlation between COVID‐19 and caesarean delivery on multivariate analysis.

Pregnancy Outcomes at a Safety Net Hospital in Atlanta, Georgia, After Changes to Abortion Legislation [ID 2683629

INTRODUCTION: On July 20, 2022, Georgia’s House Bill 481 (HB 481) went into effect for the first time since it passed state legislature in March 2019. House Bill 481 is an abortion ban in the presence of fetal cardiac activity. To date, no study has explored the law’s effects on key clinical indicators of maternal morbidity and mortality. The purpose of this study is to examine whether enactment of HB 481 has been associated with changes pregnancy-related morbidity at a safety net hospital in Atlanta, Georgia. METHODS: We are using an interrupted time series retrospective study design to evaluate trends in pregnancy complications at Grady Memorial Hospital between July 2021 and August 2023. The Emory IRB has approved this study. RESULTS: Of the 4,886 encounters linked to pregnancy outcomes included, 2,299 occurred in the year prior to enactment of HB 481 versus 2,587 in the year after. Preliminary crude data analysis demonstrated increases in rare outcomes post-enactment period compared to the pre-enactment period, specifically risk of progression to sepsis among those with preterm prelabor rupture of membranes (0.080 versus 0.061) and maternal intensive care unit admission (0.0085 versus 0.0070). There were no significant changes in the overall rate of delivery or encounters for miscarriage and a decrease in overall composite risk of severe maternal morbidity events (0.061 versus 0.074). CONCLUSION: In this rapidly changing legal landscape and with many laws similar to HB 481 being enacted in states across the United States, it is essential to continue to document the direct health effects of restrictive abortion policy on pregnancy outcomes.

Postpartum Outcomes in Patients Receiving Venous Thromboembolism Prophylaxis during Antepartum Admission.

We evaluated if venous thromboembolism (VTE) prophylaxis in the inpatient antepartum period was associated with wound hematomas, VTE occurrence, and other adverse outcomes. This study is a secondary analysis of a retrospective cohort of patients who delivered at University of Alabama at Birmingham (UAB). Patients receiving outpatient anticoagulation (AC) were excluded. We grouped patients into those who received inpatient antepartum prophylactic AC and those who did not. The primary outcome was wound hematomas from delivery to 6 weeks postpartum (PP). Secondary outcomes included VTE occurrence and select adverse outcomes, including other wound complications, unplanned procedures, mode of anesthesia, and intensive care unit (ICU) admission. Analyses were performed with no AC group as the reference. A sensitivity analysis excluding those who received inpatient PP AC was performed. Of 1,035 included patients, only 169 patients received inpatient prophylactic AC. They were older, had higher body mass indices, and more comorbidities. Patients receiving inpatient antepartum AC had higher wound hematomas (adjusted odds ratio [aOR] 23.81; 95% confidence interval [CI] 7.04-80.47). They had similar risk for developing VTE as the control group (aOR 2.68; 95% CI 0.19-37.49) but were more likely to have wound complications (aOR 2.36; 95% CI 1.24-4.47), maternal deaths (p < 0.05), and require PP ICU admission (aOR 13.38; 95% CI 4.79-37.35). When excluding those receiving any PP AC, there was no difference in bleeding complications between the two groups and VTE rates remained unchanged. Rates of maternal deaths and PP ICU admissions remained higher in those who received inpatient antepartum AC prophylaxis. In this small cohort study, increased wound hematomas were found in those who received inpatient antepartum AC prophylaxis with no difference in VTE occurrence. While adverse events were increased in the inpatient AC group, this was mostly associated with PP AC prophylaxis. Larger studies should be conducted to describe the true benefits and risks of antepartum AC prophylaxis and determine efficacy of this widely used practice. · Peripartum chemoprophylaxis is associated with increased wound hematomas.. · VTE is rare, despite its association with significant peripartum morbidity/mortality.. · Large studies are needed to guide practices that optimize the risk/benefit ratio of chemoprophylaxis..

Maternal and Fetal Outcomes in Pregnancy in the Fifth Decade of Life and Beyond

ObjectivesThe objective is to evaluate maternal and fetal outcomes at an extremely advanced maternal age (AMA) (over age 50 years) in Calgary. The secondary objective is to determine if there is a role in protocolizing complex care plans for patients at extreme AMAs. MethodsA retrospective chart review was conducted of all pregnancies ≥20 weeks gestation in patients over the age of 50 years that delivered in Calgary between January 2007 and December 2021. Pregnancy data were collected, including maternal age, pre-existing medical conditions, mode and timing of delivery, neonatal outcomes, neonatal intensive care unit (NICU) and adult intensive care unit (ICU) admissions, postpartum complications, and maternal or neonatal death. Data were extracted for maternity patients as well as neonatal ICU databases. Maternal and neonatal outcomes were assessed until discharge from hospital. ResultsAll 23 pregnancies identified were achieved through assisted reproductive technologies. Comorbidities varied, but the most common comorbidities included hypertension and gestational diabetes. Cesarean delivery was the most common form of delivery. Three cases involved postpartum maternal ICU admission. Neonatal outcomes included gestational ages of 22–39 weeks and birth weights of 486–3593 g, with 8 confirmed NICU admissions. The most common neonatal complications were jaundice and small for gestational age. ConclusionsExtremely AMA patients are more likely to have pre-existing comorbidities and develop comorbidities during pregnancy. The potential for adverse maternal and fetal outcomes is greater for these pregnancies; however, the complications are diverse and developing a universal complex care plan is difficult.

The impact of a trial of labor after cesarean versus elective repeat cesarean delivery: A meta-analysis.

The increasing global incidence of cesarean section has prompted efforts to reduce cesarean delivery rates. A trial of labor after cesarean (TOLAC) has emerged as an alternative to elective repeat cesarean delivery (ERCD) for women with a prior cesarean delivery. However, the available evidence on the comparative outcomes of these 2 options remains inconsistent, primarily due to varying advantages and risks associated with each. Our meta-analysis aims to compare the maternal-neonatal results in TOLAC and ERCD in women with prior cesarean deliveries. A comprehensive search was performed in PubMed, Embase, Cochrane library databases up to September,2022 to identity studies evaluating perinatal outcomes in women who underwent TOLAC compared to ERCD following a previous cesarean delivery. The included studies were subjected to meta-analysis using RevMan 5.3 software to assess the overall findings. A total of 13 articles were included in this meta-analysis. Statistically significant differences were identified in the rate of uterine rupture (OR = 2.01,95%CI = 1.48-2.74, P < .00001) and APGAR score < 7 at 5 minutes (OR = 2.17,95%CI = 1.69-2.77, P < .00001) between the TOLAC and ERCD groups. However, no significant differences were observed in the rates of hysterectomy, maternal blood transfusion, postpartum infection, postpartum hemorrhage and neonatal intensive care unit (P ≥ .05) admission between the 2 groups. Our analysis revealed that TOLAC is associated with a higher risk of uterine rupture and lower incidence APGAR score < 7 at 5 minutes compared to ERCD. It is vital to consider predictive factors when determining the appropriate mode of delivery in order to ensure optimal pregnancy outcomes. Efforts should be made to identify the underlying causes of adverse outcomes and implement safety precautions to select suitable participants and create safe environments for TOLAC.

Co-existing chronic hypertension and hypertensive disorders of pregnancy and associated adverse pregnancy outcomes

Objective Chronic hypertension (CHTN) causes vascular damage and resistance in the pregnant person and malperfusion in the placenta which may worsen the endothelial dysfunction of hypertensive disorders of pregnancy (HDP). These conditions frequently co-exist. A cumulative effect has been inconsistently demonstrated in prior studies, and it is unclear how co-existing hypertensive conditions affect pregnancy outcomes. We sought to examine maternal and neonatal outcomes in pregnancies affected by co-existing CHTN and HDP and compare these outcomes to those of pregnancies which were unaffected or affected by either condition alone. Methods This is a retrospective cohort study of singleton deliveries at a single institution 1 October 2013 to 1 October 2021. Data were extracted from the electronic medical record using standardized definitions and billing and diagnosis codes. Pregnant people with no evidence of hypertensive condition were compared to those with CHTN only, HDP only, and co-existing CHTN and HDP. Demographics, baseline clinical data, and use of aspirin or antihypertensive medications were assessed. Maternal outcomes included cesarean delivery, critical range blood pressure, intensive care unit (ICU) admission, and death. Neonatal outcomes included preterm birth <37 weeks’ gestation, small for gestational age (SGA) birthweight, ICU admission, and a morbidity composite. Bivariate tests of association were performed using Chi-square test. Crude and adjusted odds ratios (aORs) were calculated using logistic regression for three maternal and four neonatal outcomes. Descriptive statistics and multivariable analyses were performed. Results Of 40,840 eligible people, 1451 (3.6%) had CHTN only; 5213 (12.8%) had HDP only; and 1890 (4.6%) had co-existing CHTN and HDP. Though odds of adverse maternal and neonatal outcomes were significantly increased for all hypertensive groups relative to the unaffected referent group, co-existing CHTN and HDP had the highest odds of cesarean delivery (aOR 1.60; 95% confidence interval (CI) 1.45–1.77), critical blood pressure (OR 41.54; 95% CI 35.96–47.99), maternal ICU admission or death (aOR 3.52; 95% CI 2.65–4.67), preterm birth (aOR 2.76; 95% CI 2.41–3.16), and SGA birthweight (aOR 1.61; 95% CI 1.39–1.87). Conclusions Hypertensive disorders of pregnancy in the setting of CHTN are associated with the highest odds of serious consequences on the pregnant person and neonate independent of maternal comorbidities and prematurity. Antihypertensive medication use lowers the odds of some adverse outcomes. Patients should be informed of heightened risks, but optimal management remains unclear.

Foetomaternal Outcomes in Pregnant Women with Corrected vs Non corrected Heart Disease: A Cross-sectional Analysis at a Tertiary Care Institute of Eastern India

Introduction: Cardiac disease in pregnancy remains a major concern, particularly in developing countries like India. Pregnancy in women with heart disease increases the risk of maternal and foetal complications. Approximately 1% to 4% of pregnant women have concomitant cardiac disease. Aim: To examine the foetomaternal outcomes of pregnant women in the corrected vs. non corrected heart disease groups. Materials and Methods: This was a cross-sectional study conducted in the Department of Obstetrics and Gynaecology at IPGME&amp;R, Kolkata, West Bengal, India, from February 2020 to July 2021. A total of 50 pregnant women were included in the present study, with 25 in the corrected heart disease group and 25 in the non corrected heart disease group. Foetomaternal outcomes, including intrapartum complications, maternal intensive care unit admission, mode of delivery, and foetal complications, were observed. Comparative analyses were conducted using the Student’s t-test and Chi-square test. The p-values &lt;0.05 was considered statistically significant. Results: Data from the present study showed that out of a total of 50 pregnant women with heart disease, the majority (60%) were young (≤25 years). Approximately 48% of women were in their second pregnancy. The most common cardiac lesion in the corrected group was closure of Atrial Septal Defect (ASD) in 8 (16%) cases, while in the non corrected group, the most common was mitral regurgitation in 11 (22%) cases. In the corrected heart disease group, 15 (30%) had a caesarean section and 10 (20%) delivered vaginally, whereas in the non corrected group, 17 (34%) had a caesarean section and 8 (16%) delivered vaginally. Adverse cardiac events occurred in 2 (4%) of the corrected group, whereas 11 (22%) were observed in the non corrected group (p-value=0.0088, significant). Preterm birth and low birth weight babies were more common in the non corrected heart disease group (p-value=0.0449, significant). Conclusion: The study concludes that most women with cardiac disease are young. Compared to the Corrected Group of Heart Disease (CGHD), the non corrected group of pregnant women are more likely to experience severe cardiac complications and require admission to the intensive care unit. The foetomaternal outcome is better in the corrected group. Successful management of pregnant women with heart disease requires a comprehensive multidisciplinary approach to optimise foetomaternal outcomes.

Comprehensive appraisal of pregnancy and neonatal outcomes in singleton pregnancies conceived via invitro fertilization in the USA (2016-2021).

We set out to compare adverse pregnancy and neonatal outcomes in singleton gestations conceived via invitro fertilization (IVF) to those conceived spontaneously. Retrospective, population-based cohort using the CDC Natality Live Birth database (2016-2021). All singleton births were stratified into two groups: those conceived via IVF, and those conceived spontaneously. The incidence of several adverse pregnancy and neonatal outcomes was compared between the two groups using Pearson's chi-square test with Bonferroni adjustments. Multivariate logistic regression was used to adjust outcomes for potential confounders. Singleton live births conceived by IVF comprised 0.86 % of the cohort (179,987 of 20,930,668). Baseline characteristics varied significantly between the groups. After adjusting for confounding variables, pregnancies conceived via IVF were associated with an increased risk of several adverse pregnancy and neonatal outcomes compared to those conceived spontaneously. The maternal adverse outcomes with the highest risk in IVF pregnancies included maternal transfusion, unplanned hysterectomy, and maternal intensive care unit admission. Increased rates of hypertensive disorder of pregnancy, preterm birth (delivery <37weeks of gestation), and cesarean delivery were also noted. The highest risk neonatal adverse outcomes associated with IVF included immediate and prolonged ventilation, neonatal seizures, and neonatal intensive care unit admissions, among others. Based on this large contemporary United States cohort, the risk of several adverse pregnancy and neonatal outcomes is increased in singleton pregnancies conceived via IVF compared to those conceived spontaneously. Obstetricians should be conscious of these associations while caring for and counseling pregnancies conceived via IVF.

Declining birth rates, increasing maternal age and neonatal intensive care unit admissions.

To describe the number of US births, maternal age at birth and NICU admissions by maternal age cohorts. Our study aims to measure NICU utilization by maternal age over time. We queried the CDC WONDER Natality database for births, NICU admissions, and maternal age at delivery from 2016 to 2021. Births and NICU admissions were analyzed by maternal age. Between 2016 and 2021, US births decreased by 7% (3,945,875 to 3,664,292/year). NICU admissions increased from 344,454 to 351,775 (+2%) and admit rate from 8.7% to 9.6%. The proportion of births by maternal age declined each year for ≤29 y but increased for ≥30 y. NICU admission rates were lowest at maternal age 20-29 y and increased with age ≥30 y. US NICUs have demonstrated a 2% increase in admissions despite a 7% decrease in births. Higher rates of NICU admissions among infants born at maternal age ≥30 y warrants investigation.

Type of delivery and perinatal outcomes in pregnant women diagnosed with COVID-19: A systematic review and meta-analysis

BackgroundThere is paucity in the literature that provides a comprehensive and evidence-based conclusion regarding this topic. ObjectiveTo compare perinatal outcomes of vaginal and caesarean section delivery in women diagnosed with COVID-19 by meta-analysis of literature. Search StrategyThe search was conducted on MEDLINE, EMBASE, LILACS, CINAHL, Scopus, Web of Science and Cochrane Database of Systematic Reviews by 25th May 2022. Selection criteriaThe inclusion criteria involved pregnant women diagnosed with COVID-19 who underwent caesarean section and those who had vaginal deliveries. Data collection and analysisThe included studies were meta-analyzed for various outcomes including: Gestational age, maternal intensive care unit admission, maternal death, prematurity, newborn birth weight, newborn intensive care unit admission, Apgar scores, newborn death, and newborn vertical transmission of COVID-19. The meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) software, version 3.3.070. Main resultsThe meta-analyses included 2,566 deliveries (866 caesarean sections and 1,700 vaginal deliveries) and identified that caesarean section was significantly associated with increased prematurity (OR 2.5 [1.7; 3.6], p < 0.001), lower birth weight (−118 g [−170; −66], p < 0.001), and a higher need for maternal (OR 9.54 [5.22; 17.43], p < 0.01) and neonatal intensive care unit intervention (OR 3.67 [2.71; 4.96], p < 0.01) compared to vaginal delivery. ConclusionCOVID-19 infection alone should not be an indication for caesarean section as there is insufficient evidence that caesarean section reduces mortality, improves birth conditions, or prevents vertical transmission. Additionally, caesarean section is associated with poorer perinatal outcomes compared to vaginal delivery.

The Association Between Maternal Short Stature and Neonatal Intensive Care Unit Admission: A Longitudinal Study in Sabah.

The rising number of newborns requiring neonatal intensive care unit (NICU) care poses immediate threats to their health and places emotional and financial burdens on families and healthcare systems. This study investigates the direct effect of maternal short stature on NICU admission in Sabah, Malaysia. A longitudinal study at Hospital Wanita Dan Kanak-Kanak Sabah (HWKKS) from 2018 to 2022 included 254 Malaysian women with singleton pregnancies and neonates born after the 37th week, excluding significant disorders, smoking/alcohol use, fetal death, and malformations. Birth weight, gestational age, and neonatal condition were recorded. The association between maternal height, low birth weight(LBW), and NICU admission was analyzed. LBW prevalence was 15.35%, with an average participant height of 147.37 cm. Maternal stature was significantly associated with LBW, with the shortest quartile (Q1) having the highest risk. LBW was significantly associated with NICU admission, with LBW newborns at a sixfold higher risk. Maternal height was also significantly associated with NICU admission, with Q1having the highest risk. The receiver operating characteristic (ROC) curve suggested combining Q1 and Q2 for the best prediction of NICU admission, indicating that shorter mothers face a higher risk of neonates requiring NICU care. Maternal short stature could be a valuable predictor of LBW and NICU admission risk. It may be a screening tool to assess these risks in healthcare settings. However, further research is needed to explore this association's underlying mechanisms and potential interventions.

Comparison of Maternal and Neonatal Outcomes between SARS-CoV-2 Variants: A Retrospective, Monocentric Study.

The impact of SARS-CoV-2 variants on maternal and neonatal outcomes during pregnancy is still poorly understood, and the emergence of different variants has further complicated our understanding of the virus's effects. This retrospective, monocentric study aimed to fill this knowledge gap by analyzing the outcomes of pregnant women with acute SARS-CoV-2 infection caused by the Alpha, Delta, and Omicron variants. The study, conducted between December 2020 and March 2022 at San Marco Hospital, included 313 pregnant women with confirmed SARS-CoV-2 infection. The results showed that the Delta variant was associated with a significantly higher incidence of adverse outcomes, such as premature births, maternal intensive care unit admission, intrauterine growth restriction, and small for gestational age infants. Additionally, the Delta variant was linked to lower Apgar scores, higher maternal and fetal mortality rates, and increased levels of various biomarkers indicating more severe illness. Finally, the Delta variant also presented a greater possibility of vertical transmission. These findings underscore the complexity of understanding the impact of SARS-CoV-2 on pregnancy outcomes, especially considering the distinctive characteristics of different variants. By better understanding the specific impacts of each variant, appropriate preventive measures and management strategies can be implemented to optimize maternal and neonatal outcomes.

Delivery of a Fetus with a Non-Reassuring Status Is Associated with Significant Maternal Morbidity

Objectives: When a labor process is complicated by non-reassuring fetal status (NRFS), obstetricians focus on delivery to optimize neonatal status. We explored maternal morbidity in the setting of NRFS. Our hypothesis is that delivery of a live newborn with NRFS is associated with significant maternal morbidity. Design, Participants, Setting, and Methods: A large retrospective cohort study of 27,886 women who delivered between January 2013 and December 2016 in a single health system was studied. Inclusion criteria included (1) women over the age of 18 at the time of admission; (2) singleton pregnancy; (3) live birth; and (4) gestational age greater than or equal to 37 weeks at the time of admission. NRFS was defined as umbilical cord pH less than or equal to 7.00, fetal bradycardia, late decelerations, and/or umbilical artery base excess ≤−12. Univariate and multivariate logistic regression and propensity score analyses were performed, and propensity score adjusted odds ratios (AOR_PS) were derived. p values <0.05 were considered statistically significant. Primary outcomes are maternal blood transfusion, maternal readmission, maternal intensive care unit (ICU) admission, and cesarean delivery in relation to umbilical artery pH, fetal bradycardia, and late decelerations. Results: Umbilical artery pH less than or equal to 7 was associated with maternal blood transfusion (AOR_PS 6.83 [95% CI 2.22–21.0, p < 0.001]), maternal readmission (AOR_PS 12.6 [95% CI 2.26–69.8, p = 0.0039]), and cesarean delivery (AOR_PS 5.76 [95% CI 3.63–9.15, p < 0.0001]). Fetal bradycardia was associated with transfusion (AOR_PS 2.13 [95% CI 1.26–3.59, p < 0.005]) and maternal ICU admission (AOR_PS 3.22 [95% CI 1.23–8.46, p < 0.017]). Late decelerations were associated with cesarean delivery (AOR_PS 1.65 [95% CI 1.55–1.76, p < 0.0001]), clinical chorioamnionitis (AOR_PS 2.88 [95% CI 2.46–3.37, p < 0.0001]), and maternal need for antibiotics (AOR_PS 1.89 [95% CI 1.66–2.15, p < 0.0001]). Umbilical artery base excess less than or equal to −12 was associated with readmission (AOR_PS 6.71 [95% CI 2.22–20.3, p = 0.0007]), clinical chorioamnionitis (AOR_PS 1.89 [95% CI 1.24–2.89, p = 0.0031]), and maternal need for antibiotics (AOR_PS 1.53 [95% CI 1.03–2.26, p = 0.0344]). Limitations: The retrospective design contributes to potential bias compared to the prospective design. However, by utilizing multivariate logistic regression analysis with a propensity score method, specifically inverse probability of treatment weighting, we attempted to minimize the impact of confounding variables. Additionally, only a portion of the data set had quantitative blood losses recorded, while the remainder had estimated blood losses. Conclusion: NRFS is associated with significant maternal complications, in the form of increased need for blood transfusions, ICU admissions, and increased infection and readmission rates. Strategies for minimizing maternal complications need to be proactively considered in the management of NRFS.

Association between fetal liver diameter and glycemic control in pregnant women with gestational diabetes: A pilot study

BackgroundThis study aimed to investigate the relationship between fetal liver length (FLL) and maternal glycemic status in pregnant women with gestational diabetes mellitus (GDM), as well as to determine whether FLL measurement in the third trimester is associated with neonatal outcomes. MethodA total of 51 singleton GDM pregnancies were included in this pilot study, and transabdominal ultrasound biometry and FLL measurements were performed between 34 and 36 weeks of gestation. Maternal indicators of glycemic control, including hemoglobin A1C (HbA1C), fasting blood sugar (FBS), and 2-h postprandial blood sugar were also evaluated during this period. The cases were followed up until delivery and maternal and neonatal outcomes were assessed to determine any correlation with FLL. ResultThe results showed a significant positive correlation between FLL and HbA1C (r = 0.464, P = 0.001), FBS (r = 0.574, P < 0.001), 2-h postprandial blood sugar (r = 0.405, P = 0.002), and AC (r = 0.515, P < 0.001). Additionally, FLL was significantly associated with fetal birth weight (r = 0.408, P = 0.003) and birth weight (r = 0.460, P = 0.001). The FLL≥95th percentile group demonstrated a higher number of polyhydramnios (p = 0.007), macrosomia (p < 0.001), and maternal intensive care unit (ICU) admissions (p = 0.006). ConclusionIn conclusion, FLL measurement during third trimester of pregnancy is an indicator of maternal glycemic regulation and can be used as a predictor of macrosomia and neonatal birth weight in GDM pregnancies.

Safety evaluation of COVID-19 vaccination during early pregnancy: A single-center prospective cohort study of Chinese pregnant women

ABSTRACT This prospective cohort study aimed to evaluate the safety of an inactivated coronavirus disease 2019 (COVID-19) vaccine in pregnant women at a tertiary hospital in Hubei, China. Pregnancy outcomes were compared between pregnant vaccinated and unvaccinated women. Composite adverse pregnancy outcomes were defined as one or more of maternal adverse outcomes (prenatal pyrexia, postpartum hemorrhage, maternal intensive care unit admission, and a prethrombotic state) and adverse neonatal outcomes (premature delivery, intrauterine fetal death or induction of labor, fetal macrosomia, fetal growth restriction, small-for-gestational age, fetal abnormalities, neonatal admission to the neonatal intensive care unit, and birth asphyxia). Of a total of 845 participants in the delivery cohort, 41.2% (348/845) received at least one dose of the COVID-19 vaccination, and 33.6% (284/845) received two doses. In total, 25.3% (88/348) of the vaccinated group were vaccinated at 0–4 weeks of pregnancy. No significant difference was found in the composite adverse outcomes between the vaccinated and unvaccinated participants, regardless of whether vaccination occurred before (44/243 [18.1%] vs. 71/497 [14.3%]; P = .17) or during early pregnancy (14/105 [13.3%] vs. 71/497[14.3%]; P = .79). These findings indicate that the pregnancy outcomes of women who received the COVID-19 vaccination, even if they were vaccinated early in pregnancy, were comparable to those of unvaccinated women. This study was registered with the Chinese Clinical Trial Center (ChiCTR2100051756).

Prenatal Health Care Outcomes Before and During the COVID-19 Pandemic Among Pregnant Individuals and Their Newborns in an Integrated US Health System

The COVID-19 pandemic accelerated the use of telemedicine. However, data on the integration of telemedicine in prenatal health care and health outcomes are sparse. To evaluate a multimodal model of in-office and telemedicine prenatal health care implemented during the COVID-19 pandemic and its association with maternal and newborn health outcomes. This cohort study of pregnant individuals using longitudinal electronic health record data was conducted at Kaiser Permanente Northern California, an integrated health care system serving a population of 4.5 million people. Individuals who delivered a live birth or stillbirth between July 1, 2018, and October 21, 2021, were included in the study. Data were analyzed from January 2022 to May 2023. Exposure levels to the multimodal prenatal health care model were separated into 3 intervals: unexposed (T1, birth delivery between July 1, 2018, and February 29, 2020), partially exposed (T2, birth delivery between March 1, 2020, and December 5, 2020), and fully exposed (T3, birth delivery between December 6, 2020, and October 31, 2021). Primary outcomes included rates of preeclampsia and eclampsia, severe maternal morbidity, cesarean delivery, preterm birth, and neonatal intensive care unit (NICU) admission. The distributions of demographic and clinical characteristics, care processes, and health outcomes for birth deliveries within each of the 3 intervals of interest were assessed with standardized mean differences calculated for between-interval contrasts. Interrupted time series analyses were used to examine changes in rates of perinatal outcomes and its association with the multimodal prenatal health care model. Secondary outcomes included gestational hypertension, gestational diabetes, depression, venous thromboembolism, newborn Apgar score, transient tachypnea, and birth weight. The cohort included 151 464 individuals (mean [SD] age, 31.3 [5.3] years) who delivered a live birth or stillbirth. The mean (SD) number of total prenatal visits was similar in T1 (9.41 [4.75] visits), T2 (9.17 [4.50] visits), and T3 (9.15 [4.66] visits), whereas the proportion of telemedicine visits increased from 11.1% (79 214 visits) in T1 to 20.9% (66 726 visits) in T2 and 21.3% (79 518 visits) in T3. NICU admission rates were 9.2% (7014 admissions) in T1, 8.3% (2905 admissions) in T2, and 8.6% (3615 admissions) in T3. Interrupted time series analysis showed no change in NICU admission risk during T1 (change per 4-week interval, -0.22%; 95% CI, -0.53% to 0.09%), a decrease in risk during T2 (change per 4-week interval, -0.91%; 95% CI, -1.77% to -0.03%), and an increase in risk during T3 (change per 4-week interval, 1.75%; 95% CI, 0.49% to 3.02%). There were no clinically relevant changes between T1, T2, and T3 in the rates of risk of preeclampsia and eclampsia (change per 4-week interval, 0.76% [95% CI, 0.39% to 1.14%] for T1; -0.19% [95% CI, -1.19% to 0.81%] for T2; and -0.80% [95% CI, -2.13% to 0.55%] for T3), severe maternal morbidity (change per 4-week interval , 0.12% [95% CI, 0.40% to 0.63%] for T1; -0.39% [95% CI, -1.00% to 1.80%] for T2; and 0.99% [95% CI, -0.88% to 2.90%] for T3), cesarean delivery (change per 4-week interval, 0.06% [95% CI, -0.11% to 0.23%] for T1; -0.03% [95% CI, -0.49% to 0.44%] for T2; and -0.05% [95% CI, -0.68% to 0.59%] for T3), preterm birth (change per 4-week interval, 0.23% [95% CI, -0.11% to 0.57%] for T1; -0.37% [95% CI, -1.29% to 0.55%] for T2; and -0.15% [95% CI, -1.41% to 1.13%] for T3), or secondary outcomes. These findings suggest that a multimodal prenatal health care model combining in-office and telemedicine visits performed adequately compared with in-office only prenatal health care, supporting its continued use after the pandemic.

Trends in maternal ICU admissions at a quaternary centre in Montreal, Canada, and impact of maternal age on critical care outcomes.

Advancing maternal age is increasingly prevalent and is associated with severe maternal morbidity often requiring intensive care unit (ICU) admission. To describe maternal ICU admissions at a quaternary care hospital in Montreal, Canada, and evaluate the association between maternal age and composite of: need for invasive interventions, ICU stay > 48 h, or maternal death. Chart review of ICU admissions during pregnancy/postpartum (2006-2016); logistic regressions to evaluate the impact of age on outcomes. With 5.1 ICU admissions per 1000 deliveries, we included 187 women (mean age 32 ± 6.3 years; 20 (10.7%) ≥ 40 years). The composite outcome occurred in 105 (56.2%) patients; there were two maternal deaths. Age ≥ 40 years increased the odds of invasive interventions (OR 4.03; 95% confidence interval [CI] 1.15-14.1) but not of the composite outcome (OR 2.30; 95% CI 0.66-8.02). Peripartum women aged ≥ 40 years had worse outcomes in ICU, with an increased need for invasive interventions.

Association between migration and severe maternal outcomes in high-income countries: Systematic review and meta-analysis.

Literature focusing on migration and maternal health inequalities is inconclusive, possibly because of the heterogeneous definitions and settings studied. We aimed to synthesize the literature comparing the risks of severe maternal outcomes in high-income countries between migrant and native-born women, overall and by host country and region of birth. Systematic literature review and meta-analysis using the Medline/PubMed, Embase, and Cochrane Library databases for the period from January 1, 1990 to April 18, 2023. We included observational studies comparing the risk of maternal mortality or all-cause or cause-specific severe maternal morbidity in high-income countries between migrant women, defined by birth outside the host country, and native-born women; used the Newcastle-Ottawa scale tool to assess risk of bias; and performed random-effects meta-analyses. Subgroup analyses were planned by host country and region of birth. The initial 2,290 unique references produced 35 studies published as 39 reports covering Europe, Australia, the United States of America, and Canada. In Europe, migrant women had a higher risk of maternal mortality than native-born women (pooled risk ratio [RR], 1.34; 95% confidence interval [CI], 1.14, 1.58; p < 0.001), but not in the USA or Australia. Some subgroups of migrant women, including those born in sub-Saharan Africa (pooled RR, 2.91; 95% CI, 2.03, 4.15; p < 0.001), Latin America and the Caribbean (pooled RR, 2.77; 95% CI, 1.43, 5.35; p = 0.002), and Asia (pooled RR, 1.57, 95% CI, 1.09, 2.26; p = 0.01) were at higher risk of maternal mortality than native-born women, but not those born in Europe or in the Middle East and North Africa. Although they were studied less often and with heterogeneous definitions of outcomes, patterns for all-cause severe maternal morbidity and maternal intensive care unit admission were similar. We were unable to take into account other social factors that might interact with migrant status to determine maternal health because many of these data were unavailable. In this systematic review of the existing literature applying a single definition of "migrant" women, we found that the differential risk of severe maternal outcomes in migrant versus native-born women in high-income countries varied by host country and region of origin. These data highlight the need to further explore the mechanisms underlying these inequities. PROSPERO CRD42021224193.
