BACKGROUNDThe effects of the novel coronavirus disease 2019 (COVID-19) in pregnancy remain relatively unknown. We present a case of second trimester pregnancy with symptomatic COVID-19 complicated by ...severe preeclampsia and placental abruption.METHODSWe analyzed the placenta for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through molecular and immunohistochemical assays and by and electron microscopy and measured the maternal antibody response in the blood to this infection.RESULTSSARS-CoV-2 localized predominantly to syncytiotrophoblast cells at the materno-fetal interface of the placenta. Histological examination of the placenta revealed a dense macrophage infiltrate, but no evidence for the vasculopathy typically associated with preeclampsia.CONCLUSIONThis case demonstrates SARS-CoV-2 invasion of the placenta, highlighting the potential for severe morbidity among pregnant women with COVID-19.FUNDINGBeatrice Kleinberg Neuwirth Fund and Fast Grant Emergent Ventures funding from the Mercatus Center at George Mason University.

This study was aimed to investigate delivery management of patients with antepartum stillbirth.
Using data from fetal death certificates and linked maternal hospital discharge records, we identified ...a population-based sample of patients with singleton antepartum stillbirth at 20 to 42 weeks of gestation in California in 2007 to 2011. Primary outcomes were intended mode of delivery and actual mode of delivery. We used multivariable regressions to examine the association between patient demographic, clinical, and hospital characteristics and their mode of delivery. Separate analysis was performed for patients who had prior cesarean delivery versus those who did not.
Of 7,813 patients with singleton antepartum stillbirth, 1,356 had prior cesarean, while 6,457 had no prior cesarean. Labor was attempted in 51.8% of patients with prior cesarean and 93.7% of patients without prior cesarean, with 76.2 and 95.8% of these patients, respectively, delivered vaginally. Overall, 18.9% of patients underwent a cesarean delivery (60.5% among those with prior cesarean and 10.2% among those without prior cesarean). Multivariable regression analysis identified several factors associated with the risk of cesarean delivery that were not medically indicated. For instance, among patients without prior cesarean, malpresentation (of which the vast majority was breech presentation) was associated with an increased likelihood of planned cesarean (adjusted odds ratio OR = 3.26, 95% confidence interval CI: 2.53-4.22) and cesarean delivery after attempting labor (adjusted OR = 3.09, 95% CI: 2.25-4.25). For both patients with and without prior cesarean, delivery at an urban teaching hospital was associated with a lower likelihood of planned cesarean and a lower likelihood of cesarean delivery after attempting labor (adjusted ORs ranged from 0.28 to 0.56,
< 0.001 for all).
Over one in six patients with antepartum stillbirth underwent cesarean delivery. Among patients who attempted labor, rate of vaginal delivery was generally high, suggesting a potential opportunity to increase vaginal delivery in this population.
· In singleton antepartum stillbirths, 18.9% underwent cesarean delivery.. · Rate of vaginal delivery was high when labor was attempted.. · Both clinical and non-clinical factors were associated with risk of cesarean delivery..
Cardiovascular disease is the leading cause of pregnancy-related death in the United States. Identification of short-term indicators of cardiovascular morbidity has the potential to alter the course ...of this devastating disease among women. It has been established that hypertensive disorders of pregnancy are associated with increased risk of cardiovascular disease 10–30 years after delivery; however, little is known about the association of hypertensive disorders of pregnancy with cardiovascular morbidity during the delivery hospitalization.
We aimed to identify the immediate risk of cardiovascular morbidity during the delivery hospitalization among women who experienced a hypertensive disorder of pregnancy.
This retrospective cohort study of women, 15–55 years old with a singleton gestation between 2008 and 2012 in New York City, examined the risk of severe cardiovascular morbidity in women with hypertensive disorders of pregnancy compared with normotensive women during their delivery hospitalization. Women with a history of chronic hypertension, diabetes mellitus, or cardiovascular disease were excluded. Mortality and severe cardiovascular morbidity (myocardial infarction, cerebrovascular disease, acute heart failure, heart failure or arrest during labor or procedure, cardiomyopathy, cardiac arrest and ventricular fibrillation, or conversion of cardiac rhythm) during the delivery hospitalization were identified using birth certificates and discharge record coding. Using multivariable logistic regression, we assessed the association between hypertensive disorders of pregnancy and severe cardiovascular morbidity, adjusting for relevant sociodemographic and pregnancy-specific clinical risk factors.
A total of 569,900 women met inclusion criteria. Of those women, 39,624 (6.9%) had a hypertensive disorder of pregnancy: 11,301 (1.9%) gestational hypertension; 16,117 (2.8%) preeclampsia without severe features; and 12,206 (2.1%) preeclampsia with severe features, of whom 319 (0.06%) had eclampsia. Among women with a hypertensive disorder of pregnancy, 431 experienced severe cardiovascular morbidity (10.9 per 1000 deliveries; 95% confidence interval, 9.9–11.9). Among normotensive women, 1780 women experienced severe cardiovascular morbidity (3.4 per 1000 deliveries; 95% confidence interval, 3.2–3.5). Compared with normotensive women, there was a progressively increased risk of cardiovascular morbidity with gestational hypertension (adjusted odds ratio, 1.18; 95% confidence interval, 0.92–1.52), preeclampsia without severe features (adjusted odds ratio, 1.96; 95% confidence interval, 1.66–2.32), preeclampsia with severe features (adjusted odds ratio, 3.46; 95% confidence interval, 2.99–4.00), and eclampsia (adjusted odds ratio, 12.46; 95% confidence interval, 7.69–20.22). Of the 39,624 women with hypertensive disorders of pregnancy, there were 15 maternal deaths, 14 of which involved 1 or more cases of severe cardiovascular morbidity.
Hypertensive disorders of pregnancy, particularly preeclampsia with severe features and eclampsia, are significantly associated with cardiovascular morbidity during the delivery hospitalization. Increased vigilance, including diligent screening for cardiac pathology in patients with hypertensive disorders of pregnancy, may lead to decreased morbidity for mothers.
Objective We sought to characterize serum angiogenic factor profile of women with complete placenta previa and determine if invasive trophoblast differentiation characteristic of accreta, increta, or ...percreta shares features of epithelial-to-mesenchymal transition. Study Design We analyzed gestational age-matched serum samples from 90 pregnant women with either complete placenta previa (n = 45) or uncomplicated pregnancies (n = 45). Vascular endothelial growth factor (VEGF), placental growth factor, and soluble form of fms-like-tyrosine-kinase-1 were immunoassayed. VEGF and phosphotyrosine immunoreactivity was surveyed in histological specimens relative to expression of vimentin and cytokeratin-7. Results Women with previa and invasive placentation (accreta, n = 5; increta, n = 6; percreta, n = 2) had lower systemic VEGF (invasive previa: median 0.8 0.02-3.4 vs control 6.5 2.7-10.5 pg/mL, P = .02). VEGF and phosphotyrosine immunostaining predominated in the invasive extravillous trophoblasts that coexpressed vimentin and cytokeratin-7, an epithelial-to-mesenchymal transition feature and tumorlike cell phenotype. Conclusion Lower systemic free VEGF and a switch of the interstitial extravillous trophoblasts to a metastable cell phenotype characterize placenta previa with excessive myometrial invasion.
Pregnancy-related maternal mortality and morbidity rates continue to increase in the United States despite global improvements in maternal outcomes. The unique hemodynamic and physiological changes ...of pregnancy results in a 3- to 4-fold increased risk of acute myocardial infarction (AMI) which causes a substantial proportion of all maternal cardiac deaths. In addition to atherosclerosis, pregnancy-associated AMI is commonly caused by nonatherosclerotic etiologies such as spontaneous coronary artery dissection, embolus to the coronary artery, and coronary vasospasm. Herein, the epidemiology, etiologies, presentation, diagnosis, and management of AMI in pregnancy is discussed along with future directions for multidisciplinary care.
With the goal of identifying factors contributing to severe maternal morbidity (SMM) at our institution, we established a formal SMM review process. We performed a retrospective cohort study ...including all SMM cases as defined by American College of Obstetricians and Gynecologists and Society for Maternal-Fetal Medicine consensus criteria that were managed at Yale-New Haven Hospital over a 4-year period. Overall, 156 cases were reviewed. The SMM rate was 0.49% (95% CI 0.40-0.58). The leading causes of SMM were hemorrhage (44.9%) and nonintrauterine infection (14.1%). Two thirds of the cases were deemed to be preventable. Preventability was mostly associated with health care professional-level (79.4%) and system-level (58.8%) factors that could coexist. Detailed case review allowed for identification of preventable causes of SMM, revealed gaps in care, and allowed for implementation of practice changes targeting health care professional-level and system-level factors.
In the United States, sexual, reproductive, and perinatal health inequities are well documented and known to be caused by a history of systemic oppression along many axes, including but not limited ...to race, ethnicity, gender, socioeconomic position, sexual orientation, and disability. Medical schools are responsible for educating students on systems of oppression and their impact on health. Reproductive justice advocates, including lay persons, medical students, and teaching faculty, have urged for integrating the reproductive justice framework into medical education and clinical practice. In response to medical student advocacy, we developed introductory didactic sessions on social and reproductive justice for preclinical medical students. These were created in a team-based learning format and include pre-course primer materials on reproductive justice. During the sessions, students engaged with hypothetical clinical vignettes in small groups to identify oppressive structures that may have contributed to the health outcomes described and potential avenues for contextually relevant and level-appropriate advocacy. The sessions took place in November 2019 (in-person) and 2020 (virtually) and were well attended by students. We highlight our experience, student feedback, and next steps, including further integration of reproductive health equity into medical school curricula in concert with department-wide education for faculty, residents, nursing, and allied health professionals. This introduction to social and reproductive justice can be adapted and scaled across different medical school curricula, enhancing the training of a new generation of physicians to become critically aware of how oppressive structures create health inequities and able to mitigate their impact through their roles as clinicians, researchers, and advocates.In the United States, sexual, reproductive, and perinatal health inequities are well documented and known to be caused by a history of systemic oppression along many axes, including but not limited to race, ethnicity, gender, socioeconomic position, sexual orientation, and disability.

Though much of routine healthcare pauses in a public health emergency, childbirth continues uninterrupted. Crises like COVID-19 put incredible strains on healthcare systems and require strategic ...planning, flexible adaptability, clear communication, and judicious resource allocation. Experiences from obstetric units affected by COVID-19 highlight the importance of developing new teams and workflows to ensure patient and healthcare worker safety. Additionally, adapting a strategy that combines units and staff from different areas and hospitals can allow for synergistic opportunities to provision care appropriately to manage a structure and workforce at maximum capacity.
Herpes simplex virus (HSV) causes only 2-4% of all acute hepatitis but has high morbidity and mortality. Pregnancy is a risk factor for HSV hepatitis. We describe a case of gestational HSV hepatitis.
...A 32-year old woman, gravida 2 para 1, presented at 38 2/7 weeks of gestation with back pain and fetal tachycardia. She became febrile after admission, had spontaneous rupture of membranes, and was delivered by cesarean for malpresentation. Postpartum, she became persistently febrile and developed transaminitis, symptomatic hypotension, and pancytopenia despite antibiotics. Imaging revealed acute liver injury, splenomegaly, pleural effusions, and cardiomyopathy. Serum polymerase chain reaction (PCR) screening identified HSV-1 infection. The patient recovered on acyclovir. There was no evidence of neonatal seroconversion.
Herpes simplex virus hepatitis causes significant morbidity, and pregnant women are susceptible to severe infections. Pregnant or peripartum women with acute febrile hepatitis require prompt evaluation for HSV with serum PCR screening.
