The Impact of Outpatient Prenatal Care Visitor Restrictions on Pregnant Patients and Partners During the COVID-19 Pandemic.

Introduction: During the early months of the COVID-19 pandemic, several health care facilities enacted visitor restrictions to help reduce the spread of SARS-CoV-2 among patients, front-line workers in health care systems, and communities. The impact and burden of policy updates on visitor restrictions put forth by the COVID-19 pandemic can be seen on patients and families, most often in the acute care setting and skilled nursing facilities. Yet, the effects of visitor restrictions in the prenatal care setting were unknown.

The Successes and Challenges of Implementing Telehealth for Diverse Patient Populations Requiring Prenatal Care During COVID-19: Qualitative Study.

Patient access to accurate information is important to manage expectations and make informed decisions. Unique aspects of medical management include monitoring tacrolimus levels and performing cervical biopsies for rejection.

Genetic Screening and Teratogenic Exposures: Considerations in Caring for the Uterus Transplant Patient.

Counseling the uterus transplant patient requires an enhanced knowledge of unique genetic challenges that include an understanding of the spectrum of Mayer-Rokitansky-Küster-Hauser syndrome. Patients should understand their options for genetic screening and testing including preimplantation genetic testing for aneuploidy, genetic screening, and diagnostic testing. This patient population is potentially at risk for fetal anomalies due to the increased susceptibility to infections, such as cytomegalovirus.

Decision-making for prenatal genetic screening: how will pregnant women navigate a growing number of aneuploidy and carrier screening options?

Background: Prenatal genetic screens, including carrier screening (CS) and aneuploidy screening (AS), comprise an important component of reproductive healthcare delivery. Clinical practice guidelines emphasize the importance of informed decision-making and patient's preferences regarding the use of these screens. Yet, it is unclear how to achieve this ideal as prenatal genetic screening options rapidly become more complex and increasingly available to patients.

Results: Reports of thirty-one live births following uterus transplantation have been published from both living and deceased donors.

The impact of the emergence of COVID-19 on women's prenatal genetic testing decisions.

Objective: We conducted a study to examine the impact of COVID on patients' access and utilization of prenatal genetic screens and diagnostic tests at the onset of the COVID-19 pandemic in the United States.

Methods: We conducted telephone interviews with 40 patients to examine how the pandemic affected prenatal genetic screening and diagnostic testing decisions during the initial months of the pandemic in the United States. An interview guide queried experiences with the ability to access information about prenatal genetic testing options and to utilize the tests when desired.

Making the most of the first prenatal visit: The challenge of expanding prenatal genetic testing options and limited clinical encounter time.

Objective: Advances in prenatal genetics place additional challenges as patients must receive information about a growing array of screening and testing options. This raises concerns about how to achieve a shared decision-making process that prepares patients to make an informed decision about their choices about prenatal genetic screening and testing options, calling for a reconsideration of how healthcare providers approach the first prenatal visit.

Methods: We conducted interviews with 40 pregnant women to identify components of decision-making regarding prenatal genetic screens and tests at this visit.

First birth from a deceased donor uterus in the United States: from severe graft rejection to successful cesarean delivery.

Uterus transplantation is the only known potential treatment for absolute uterine factor infertility. It offers a unique setting for the investigation of immunologic adaptations of pregnancy in the context of the pharmacologic-induced tolerance of solid organ transplants, thus providing valuable insights into the early maternal-fetal interface. Until recently, all live births resulting from uterus transplantation involved living donors, with only 1 prior birth from a deceased donor.

New Frontier: Role of the Radiologist in Uterine Transplantation.

Uterine transplantation (UT) is a novel treatment for absolute uterine factor infertility (AUFI) that is currently being performed under experimental protocols in multiple medical centers worldwide. At the time of this publication, there have been at least 10 live births by women with a transplanted uterus. As successful outcomes from this innovative procedure increase, it is likely that more centers will perform UT.

Pregnancy-Associated Cardiac Hypertrophy in Corin-Deficient Mice: Observations in a Transgenic Model of Preeclampsia.

Background: Preeclampsia increases the risk of heart disease. Defects in the protease corin, including the variant T555I/Q568P found in approximately 12% of blacks, have been associated with preeclampsia and cardiac hypertrophy. The objective of this study was to investigate the role of corin and the T555I/Q568P variant in preeclampsia-associated cardiac alterations using genetically modified mouse models.

Deceased Donor Uterine Transplantation: Innovation and Adaptation.

This commentary endeavors to share our practical experience in developing and implementing the first uterine transplant clinical trial in the United States. Uterine transplant is a promising novel treatment for uterine factor infertility. After reported successful live births after uterine transplant in Sweden, research teams around the world are either embarking on or are considering the development of uterine transplant protocols.

Angiogenic factors in superimposed preeclampsia: a longitudinal study of women with chronic hypertension during pregnancy.

Imbalances in circulating angiogenic factors contribute to the pathogenesis of preeclampsia. To characterize levels of angiogenic factors in pregnant women with chronic hypertension, we prospectively followed 109 women and measured soluble fms-like tyrosine kinase 1 (sFlt1), soluble endoglin, and placental growth factor at 12, 20, 28, and 36 weeks' gestation and postpartum. Superimposed preeclampsia developed in 37 (34%) and was early onset (<34 weeks) in 9 and later onset (≥34 weeks) in 28.

Interpregnancy change in smoking habits and risk of preeclampsia: a population-based study.

Background: Maternal smoking has been associated with decreased risk of preeclampsia; however, it is uncertain whether this association is causal. An argument for causality would be strengthened if changes in smoking status across consecutive pregnancies were related to the risk of preeclampsia.

Methods: We used data from the National Swedish Birth Register to ascertain the associations between changes in smoking status during the first two successive pregnancies and risk of preeclampsia in the second pregnancy in 371,627 women between 1992 and 2006.

Methods of induction of labour: a systematic review.

Background: Rates of labour induction are increasing. We conducted this systematic review to assess the evidence supporting use of each method of labour induction.

Methods: We listed methods of labour induction then reviewed the evidence supporting each.

Maternal serum lipids during pregnancy and infant birth weight: the influence of prepregnancy BMI.

Maternal obesity may be associated with metabolic factors that affect the intrauterine environment, fetal growth, and the offspring's long-term risk for chronic disease. Among these factors, maternal serum lipids play a particularly important role. Our objective was to estimate the influence of variation in maternal serum lipid levels on variation in infant birth weight (BW) in overweight/obese and normal weight women.

Endogenous adenosine down-modulates mid-trimester intraamniotic tumor necrosis factor-alpha production.

Problem: To determine whether adenosine in amniotic fluid down-regulates pro-inflammatory cytokine production.

Method Of Study: Mid-trimester amniotic fluid from 21 women was incubated ex vivo in the presence or absence of human adenosine deaminase, the enzyme that irreversibly degrades adenosine. After 24 hr, supernatants were assayed by ELISA for tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-6, and IL-10.

Hyaluronan modulates pro-inflammatory immune activity in the mid-trimester amniotic cavity.

Hyaluronan (HA), which comprises repeating disaccharides of D-glucuronic acid and N-acetyl-glucosamine, is a component of the extracellular matrix. In response to infection or tissue injury HA is released into the extracellular milieu where it modulates immune activity. We hypothesized that HA is present in mid-trimester amniotic fluid and contributes to immune regulation at that site.

Gelsolin down-regulates lipopolysaccharide-induced intraamniotic tumor necrosis factor-alpha production in the midtrimester of pregnancy.

Objective: The purpose of this study was to identify gelsolin in midtrimester amniotic fluid and evaluate its interaction with lipopolysaccharide (LPS).

Study Design: Supernatants from 40 midtrimester amniotic fluid samples were incubated with Escherichia coli LPS, and gelsolin binding was measured by enzyme-linked immunosorbent assay. Unfractionated aliquots of 25 of the fluids were cultured ex vivo for 24 hours in the presence of LPS and supernatants tested for tumor necrosis factor (TNF)-alpha and interleukin (IL)-10 production, and the influence of antigelsolin antibody was evaluated.
