Critical Care (London, England) Sep 2023We examined the risk of severe life-threatening morbidity in pregnant patients with Covid-19 infection.
BACKGROUND
We examined the risk of severe life-threatening morbidity in pregnant patients with Covid-19 infection.
METHODS
We conducted a population-based study of 162,576 pregnancies between March 2020 and March 2022 in Quebec, Canada. The main exposure was Covid-19 infection, including the severity, period of infection (antepartum, peripartum), and circulating variant (wildtype, alpha, delta, omicron). The outcome was severe maternal morbidity during pregnancy up to 42 days postpartum. We estimated risk ratios (RR) and 95% confidence intervals (CI) for the association between Covid-19 infection and severe maternal morbidity using adjusted log-binomial regression models.
RESULTS
Covid-19 infection was associated with twice the risk of severe maternal morbidity compared with no infection (RR 2.02, 95% CI 1.76-2.31). Risks were elevated for acute renal failure (RR 3.01, 95% CI 1.79-5.06), embolism, shock, sepsis, and disseminated intravascular coagulation (RR 1.35, 95% CI 0.95-1.93), and severe hemorrhage (RR 1.49, 95% CI 1.09-2.04). Severe antepartum (RR 13.60, 95% CI 10.72-17.26) and peripartum infections (RR 20.93, 95% CI 17.11-25.60) were strongly associated with severe maternal morbidity. Mild antepartum infections also increased the risk, but to a lesser magnitude (RR 3.43, 95% CI 2.42-4.86). Risk of severe maternal morbidity was around 3 times greater during circulation of wildtype and the alpha and delta variants, but only 1.2 times greater during omicron.
CONCLUSIONS
Covid-19 infection during pregnancy increases risk of life-threatening maternal morbidity, including renal, embolic, and hemorrhagic complications. Severe Covid-19 infection with any variant in the antepartum or peripartum periods all increase the risk of severe maternal morbidity.

BACKGROUND
Preeclampsia is a pregnancy-specific hypertensive disorder associated with an imbalance in circulating proangiogenic and antiangiogenic proteins. Preclinical evidence implicates microvascular dysfunction as a potential mediator of preeclampsia-associated cardiovascular risk.
METHODS
Women with singleton pregnancies complicated by severe antepartum-onset preeclampsia and a comparator group with normotensive deliveries underwent cardiac positron emission tomography within 4 weeks of delivery. A control group of premenopausal, nonpostpartum women was also included. Myocardial flow reserve, myocardial blood flow, and coronary vascular resistance were compared across groups. sFlt-1 (soluble fms-like tyrosine kinase receptor-1) and PlGF (placental growth factor) were measured at imaging.
RESULTS
The primary cohort included 19 women with severe preeclampsia (imaged at a mean of 15.3 days postpartum), 5 with normotensive pregnancy (mean, 14.4 days postpartum), and 13 nonpostpartum female controls. Preeclampsia was associated with lower myocardial flow reserve (β, -0.67 [95% CI, -1.21 to -0.13]; =0.016), lower stress myocardial blood flow (β, -0.68 [95% CI, -1.07 to -0.29] mL/min per g; =0.001), and higher stress coronary vascular resistance (β, +12.4 [95% CI, 6.0 to 18.7] mm Hg/mL per min/g; =0.001) versus nonpostpartum controls. Myocardial flow reserve and coronary vascular resistance after normotensive pregnancy were intermediate between preeclamptic and nonpostpartum groups. Following preeclampsia, myocardial flow reserve was positively associated with time following delivery (=0.008). The sFlt-1/PlGF ratio strongly correlated with rest myocardial blood flow (=0.71; <0.001), independent of hemodynamics.
CONCLUSIONS
In this exploratory cross-sectional study, we observed reduced coronary microvascular function in the early postpartum period following preeclampsia, suggesting that systemic microvascular dysfunction in preeclampsia involves coronary microcirculation. Further research is needed to establish interventions to mitigate the risk of preeclampsia-associated cardiovascular disease.

Endometriosis is a major cause of infertility, and considering its pathophysiology, it is expected to affect pregnancy outcomes as well. This study aimed to evaluate whether endometriosis is associated with adverse pregnancy outcomes after successful conception. Data from singleton pregnancy deliveries between January 2014 and October 2019 were obtained from the Korean Health Insurance Review and Assessment Service database. We compared the clinical characteristics and adverse pregnancy outcomes of women with and without endometriosis. A total of 1,251,597 pregnant women were enrolled; of these, 32,951 (2.6%) were assigned to the endometriosis group. Women with endometriosis had significantly more adverse pregnancy outcomes than those without endometriosis. Adverse pregnancy outcomes associated with endometriosis included preterm labor, preterm birth, preeclampsia, fetal growth restriction, placenta previa, placental abruption, antepartum and postpartum hemorrhage, and stillbirth. This study also showed an increased risk of postpartum hemorrhage, blood transfusion, uterine artery embolization, and cesarean hysterectomy in the endometriosis group compared to the non- endometriosis group. The cesarean delivery rate was significantly higher in the endometriosis group than in the non-endometriosis group, even after excluding cases of antenatal obstetric complications that could increase the risk of cesarean delivery. Women with endometriosis not only have difficulty conceiving, but also have a significantly higher risk of adverse pregnancy outcomes.

INTRODUCTION AND AIM
Antepartum hemorrhage (APH) is one of the deadliest complications in obstetrics. It can complicate about 2-5% of pregnancies. It contributes significantly to maternal and perinatal mortality and morbidity during pregnancy and childbearing worldwide. The aim of this study was to determine maternal and fetal outcomes in patients presenting with APH.
MATERIALS AND METHODS
This was a retrospective study. Pregnant women with >28 weeks gestation reporting to the Department of Obstetrics and Gynecology from May 2021 to April 2022 were included in the study. Ethical approval from the institutional ethical committee was taken.
RESULT
This study included 76 patients of APH. Most patients in the analysis were found to be second gravida (30%). Anemia was the most common associated morbidity (51.31%). 58% of these patients were of placenta previa, 14% were of abruption, and 10% were of accreta. Among all patients, 94.74% recovered well. 2.63% of cases could not be saved and resulted in maternal mortality. The proportions of babies alive, intra-uterine death (IUD), and intubated were 86.84%, 11.84%, and 1.32%, respectively. 17.1% of patients required a lifesaving cesarean hysterectomy.
CONCLUSION
APH is an obstetrical emergency that requires timely diagnosis and early intervention. Swift management is required to improve maternal and fetal outcomes.

Background Urinary incontinence is a condition that causes social, medical, or hygienic problems. The increase in the incidence of stress incontinence, particularly with increasing parity, emphasizes the role of pregnancy on the etiology of incontinence and other urinary symptoms. This study aimed to estimate the effect of pregnancy on urinary incontinence and other urinary symptoms with history and urodynamic data. Methodology This study was conducted at Mustafa Kemal University, Medical Faculty, Obstetrics and Gynecology Department. A total of 72 pregnant primigravid women without any urinary problems were included in the study. Patients with severe chronic disease, neurological disorders, antepartum hemorrhage, multiple pregnancies, younger than 18, and those with physical and mental disabilities were excluded. All patients were initially evaluated in the first trimester and finally in the sixth week of the postpartum period. Demographic and obstetric data, including urological complaints and urodynamic findings, were recorded. Results There were significant increases in nocturia, frequency, dysuria, urgency, and stress urinary incontinence complaints in pregnant women. Urge incontinence was not significantly different after pregnancy. In the postpartum urodynamic studies, nine (12.5%) patients with stress urinary incontinence and six (8.3%) patients with detrusor instability were detected. There was no significant difference between cesarean section and vaginal delivery regarding incontinence. Conclusions According to the study findings, pregnant women who were continent before pregnancy could become incontinent after birth according to urodynamic data. However, long-term studies are needed to determine whether this incontinence is temporary. Additionally, according to our results, cesarean section should not be recommended over vaginal delivery only to prevent incontinence.

Placenta previa (PP) is one such complication related to several adverse pregnancy outcomes. Adverse outcomes are likely greater if PP coexists with antepartum hemorrhage (APH). This study aims to evaluate the risk factors and pregnancy outcomes of APH in women with PP. This retrospective case-control study included 125 singleton pregnancies with PP who delivered between 2017 and 2019. Women with PP were divided into two groups: PP without APH (n = 59) and PP with APH (n = 66). We investigated the risk factors associated with APH and compared the differences between both groups in placental histopathology lesions due to APH and the resulting maternal and neonatal outcomes. Women with APH had more frequent antepartum uterine contractions (33.3% vs. 10.2%, P = .002) and short cervical length (< 2.5 cm) at admission (53.0% vs. 27.1%, P = .003). The placentas from the APH group had lower weight (442.9 ± 110.1 vs. 488.3 ± 117.7 g, P = .03) in the gross findings, and a higher rate of villous agglutination lesions (42.4% vs. 22.0%, P = .01) in the histopathologic findings. Women with APH in PP had higher rates of composite adverse pregnancy outcomes (83.3% vs. 49.2%, P = .0001). Neonates born to women with APH in PP had worse neonatal outcomes (59.1% vs. 23.9%, P = .0001). Preterm uterine contractions and short cervical length were the most significant risk factors for APH in PP.
