RESUMO
OBJECTIVE: This study aims to explore vaccination acceptance among individuals with a history of preterm birth between March and June during the pre-COVID (2019), early-COVID (2020), and late-COVID (2021) periods. STUDY DESIGN: This is a cross-sectional, retrospective cohort study of pregnant individuals with a history of preterm birth (<37 weeks' gestation) who initiated care of a subsequent pregnancy during pre-COVID (March-June 2019), early-COVID (March-June 2020), or late-COVID (March-June 2021). The primary outcome of interest was vaccination status for influenza, Tdap, and COVID-19 vaccines. Fisher's exact and chi-square tests were used to investigate association between vaccination status and time periods, race/ethnicity, and insurance. RESULTS: Among 293 pregnancies, influenza vaccination rate was highest in early-COVID (p < 0.05). There was no statistically significant difference in Tdap or COVID-19 vaccination between time periods. COVID-19 vaccination was highest in individuals with private insurance (p < 0.05). There was no statistically significant difference in vaccination status by race/ethnicity. CONCLUSION: In this study on high-risk pregnant individuals, the majority of our cohort remained unvaccinated against COVID-19 into the late-COVID period. Additionally, their influenza vaccination rates were greater than the national average in early-COVID and substantially lower than the national average in late-COVID. This shift in influenza vaccination acceptance may have been sparked by COVID-19 vaccine distribution beginning in January 2021 leading to overall vaccination hesitancy. Standardized guidelines and counseling concerning prenatal safety in recommended immunizations may serve as important tools of reassurance and health promotion. KEY POINTS: · Maternal infections during pregnancy are a risk factor for preterm birth.. · High-risk cohort had low influenza vaccination post-COVID possibly due to COVID-19 vaccine hesitancy.. · Vaccination education may be a uniquely important tool among high-risk pregnant patients..

BACKGROUND: Patients with preeclampsia are at high risk for long-term cardiovascular events, yet the short-term, acute cardiovascular complications that follow preeclampsia are understudied. The objective of this study was to compare the short-term, acute maternal cardiovascular morbidity events after delivery among patients with a diagnosis of preeclampsia versus those without this diagnosis. METHODS: In this retrospective cohort study, the Premier inpatient database was used to examine a cohort of obstetric patients older than 18 years, who delivered from January 1, 2016, to September 30, 2020. A diagnosis of preeclampsia and preeclampsia with severe features during delivery hospitalization were the exposures of interest. The primary outcome was a composite of maternal cardiovascular morbidity events during delivery hospital admission. The secondary outcome was the occurrence of maternal cardiovascular morbidity events during a readmission within 90 days of delivery hospitalization. RESULTS: In total, 4,488,759 patients met inclusion criteria, of which 158,114 (3.5%) were diagnosed with preeclampsia without severe features, and 117,940 (2.6%) with preeclampsia with severe features. Adjusted odds of maternal cardiovascular morbidity events were higher in patients with preeclampsia and in those with preeclampsia with severe features compared with those without preeclampsia during delivery hospitalization (adjusted odds ratio [OR] [95% confidence interval {CI}] 1.87 [1.78-1.97] and 4.74 [4.44-5.05], respectively) and within 90 days (adjusted OR [95% CI] 2.01 [1.83-2.21] and 2.32 [2.10-2.57], respectively). CONCLUSIONS: Patients with both preeclampsia and preeclampsia with severe features have higher rates of maternal cardiovascular morbidity events than those without preeclampsia. Future studies are necessary to examine which patients with preeclampsia are at highest risk for cardiovascular complications.

OBJECTIVE: The COVID pandemic has been associated with varied effects on preterm birth (PTB). We sought to compare rates of PTB during the pre- and post vaccination COVID periods with pre-pandemic PTB rates, stratified by race and ethnicity. STUDY DESIGN: Retrospective cohort comparing all deliveries over 20 weeks at a single tertiary center during "early" (March 2020-June 2020) versus "late" COVID (March 2021-June 2021), and "late" COVID versus pre-COVID (March to June 2014-2019). PTBs <37, <34, and <28 weeks were compared and stratified by race/ethnicity. RESULTS: A total of 16,483 deliveries occurred including 2,068 "early" COVID, 2,115 "late" COVID, and 12,300 pre-COVID. The PTB rate during "late" COVID was lower compared to "early" COVID (12.1 vs. 14.6%, p = 0.02). Rate of PTB <34 was also lower during "late" COVID (4.4 vs. 5.7%, p = 0.05). PTB <28 did not differ. When controlling for prior PTB, "late" COVID remained associated with a decreased risk of PTB compared to "early" COVID, adjusted odds ratio (aOR) of 0.82 (95% confidence interval [CI]: 0.68, 0.98). Although there was no difference in PTB among Hispanic individuals when comparing "late" COVID versus pre-COVID, when further subdivided, a small number of Hispanic Puerto Rican individuals had higher odds of PTB < 37 during "late" COVID versus pre-COVID (aOR = 4.29 [95% CI: 1.12, 16.4]). Additionally, White individuals had reduced odds of PTB <37 (aOR = 0.80 [95% CI: 0.65, 0.98]) during "late" COVID versus pre-COVID while the PTB rate was unchanged when comparing "late" COVID versus pre-COVID in all other racial and ethnic groups. CONCLUSION: During 2021, PTB rates decreased from rates observed in 2020 at the height of COVID restrictions. Among White birthing individuals, PTB decreased in 2021 compared to pre-COVID rates. This decrease was not observed in Black and Hispanic birthing individuals. These data highlight the continued racially disparate impact of the COVID-19 pandemic on PTB rates. KEY POINTS: · The COVID-19 pandemic has been associated with varied effects on the preterm birth (PTB) rate.. · PTB rates decreased in "late" COVID compared to "early" COVID.. · When stratified, PTB decreased among white individuals, but not in Black or Hispanic individuals..
RESUMO
OBJECTIVE: The primary aim of this study was to examine the United States Preventative Services Task Force (USPSTF) guidelines concordant low-dose aspirin (LDA) counseling and factors associated with counseling in nulliparous birthing individuals. STUDY DESIGN: We conducted a retrospective cohort study of nulliparous birthing individuals who delivered between January 1, 2019 and June 30, 2020 and received prenatal care at the Duke High Risk Obstetrical Clinics (HROB). All nulliparous patients over 18 years old who established or transferred care to HROB by 16 weeks, 6 days were included in the analysis. We excluded patients with more than two previous first-trimester pregnancy losses, multiple gestation, a known contraindication to LDA, initiation of LDA prior to their prenatal care, or documented medical history of coagulation disorder. Bivariate associations between demographic/medical characteristics and our primary outcome, receipt of counseling (yes/no), were assessed using two-sample t-tests for continuous variables and chi-square or Fisher's exact test for categorical variables. Factors significantly associated with the primary outcome (p < 0.05) were entered into the multivariable logistic regression model. RESULTS: Among 391 birthing individuals included in the final analysis cohort, 51.7% of eligible patients received guideline consistent LDA counseling. Factors associated with increased odds of LDA counseling were advanced maternal age (adjusted odds ratio [aOR]: 1.05, 95% confidence interval [CI]: 1.01-1.09), Black race compared with White race (aOR:1.75, 95% CI: 1.03-2.98), chronic hypertension (aOR: 4.17, 95% CI: 1.82-9.55), and obesity (aOR: 5.02, 95% CI: 3.12-8.08). CONCLUSION: Approximately half of all nulliparous birthing individuals had appropriately documented LDA counseling. The USPSTF guidelines on LDA for preeclampsia risk reduction are complex, which may lead to ineffective provider adherence. Efforts to simplify guidelines and improve LDA counseling are vital to ensuring this low-cost, evidence-based preeclampsia prevention is used in a consistent and equitable manner. KEY POINTS: · A total of 51.7% of eligible patients received guideline consistent LDA counseling.. · Advanced maternal age , body mass index > 30, Black race, and chronic hypertension associated with increased odds of counseling.. · Among patients most likely to be counseled, high numbers did not receive LDA counseling..
RESUMO
OBJECTIVE: We sought to describe rates of breastmilk feeding (BF) at hospital discharge and 6 weeks postpartum and to identify risk factors for noninitiation or cessation among pregnancies complicated by preterm prelabor rupture of membranes (PPROM). STUDY DESIGN: Retrospective cohort study of pregnant persons with PPROM admitted to a single tertiary center (2013-2019). Patients with deliveries complicated by intrauterine or neonatal demise or with incomplete BF data were excluded. Demographic, antepartum, and delivery characteristics were evaluated. Primary analysis identified rate of BF initiation at maternal discharge and factors associated with noninitiation. Secondary analysis evaluated BF continuation and factors associated with cessation at 6 weeks postpartum. Bivariate statistics were used to compare characteristics and logistic regression was used to estimate adjusted odds ratios (aOR). RESULTS: Of 397 patients with PPROM, 342(86%) initiated BF prior to discharge. Those reporting tobacco use in pregnancy were less likely to initiate BF (aOR: 0.32; 95% confidence interval [CI]: 0.16, 0.64). In contrast, private insurance (aOR: 2.53; 95% CI: 1.19, 5.37) and pregnancy latency ≥ 14 days (aOR: 3.02; 95% CI: 1.09, 8.38) were associated with BF initiation at hospital discharge. Of the 293 patients with postpartum follow-up, only 214 (73%) had BF continuation at 6 weeks postpartum. Maternal age <20 years (aOR: 0.07; 95% CI: 0.01, 0.68) and multiparity (aOR: 0.54; 95% CI: 0.29, 0.99) were associated with BF cessation. Patients with private insurance were observed to have increased odds of BF continuation (aOR: 2.10; 95% CI: 1.07, 4.12). CONCLUSION: Among patients with PPROM, tobacco use may be associated with noninitiation of BF prior to discharge, whereas age < 20 years and multiparity were associated with cessation by 6 weeks postpartum. Longer pregnancy latency ≥ 14 days was associated with BF initiation prior to discharge. Private insurance was associated with increased rates of BF initiation and continuation postpartum. BF education and support should be offered to all patients admitted for PPROM. KEY POINTS: · Tobacco use may be associated with BF noninitiation.. · Young age and multiparity are linked with BF cessation.. · Private insurance resulted in BF initiation and continuation..
RESUMO
Profound inequities in maternal and infant outcomes based on race exist, and the maternal-fetal medicine community has an important role in eliminating these disparities. Accurately employing race and ethnicity as social constructs within research that guides clinical practice is essential to achieving health equity. We must abandon commonly propagated myths that race is a surrogate for genetics or economic status and that data are exempt from potential bias. These myths can lead to harmful misconceptions that exacerbate racial disparities in maternal and infant health outcomes. Furthermore, these myths obscure racism as the true underlying etiology of racial disparities. Understanding that race is a social construct and using an antiracist approach to research are essential in combating racism and eliminating unacceptable disparities in maternal and infant health. This document provides specific suggestions to approach the research process with an antiracist framework.

OBJECTIVES: The US preterm birth rate varies dramatically by race and ethnicity yet the racial and ethnic representation within studies evaluating 17-hydroxprogesterone caproate (17-P) for preterm birth prevention is unknown. The objectives of our study were to 1) examine the racial and ethnic representation of participants in 17-P preterm birth prevention studies, 2) evaluate adherence to the NIH race and ethnicity reporting guidelines and 3) compare racial and ethnic representation in research studies to national preterm birth incidence. METHODS: We systematically reviewed US studies published between January 2000 and December 2019. Study participant's race and ethnicity were reported using descriptive statistics then compared to US 2017//2018 preterm birth data using Pearson's chi-square. RESULTS: Eighteen studies met the inclusion criteria, 17 studies reported race, 11 studies reported ethnicity, and yet none of the studies followed the NIH criteria. Compared to 2017/2018 US preterm births, the proportion of black/African American study participants was significantly higher whereas the proportions of all other race categories were lower. CONCLUSIONS: More detailed reporting of race and ethnicity is needed in 17-P literature. Black women appear to be well represented while other racial and ethnic groups may be understudied.

BACKGROUND: Pregnant women with a history of preterm birth are at risk for recurrence, often requiring frequent prenatal visits for close monitoring and/or preventive therapies. Employment demands can limit uptake and adherence to recommended monitoring and preterm birth prevention therapies. METHOD: We conducted a qualitative descriptive study using in-depth interviews (IDIs) of pregnant women with a history of preterm birth. IDIs were conducted by trained qualitative interviewers following a semi-structured interview guide focused on uncovering barriers and facilitators to initiation of prenatal care, including relevant employment experiences, and soliciting potential interventions to improve prompt prenatal care initiation. The IDIs were analyzed via applied thematic analysis. RESULTS: We described the interview findings that address women's employment experiences. The current analysis includes 27 women who are majority self-described as non-Hispanic Black (74%) and publically insured (70%). Participants were employed in a range of professions; food services, childcare and retail were the most common occupations. Participants described multiple ways that being pregnant impacted their earning potential, ranging from voluntary work-hour reduction, involuntary duty hour reductions by employers, truncated promotions, and termination of employment. Participants also shared varying experiences with workplace accommodations to their work environment and job duties based on their pregnancy. Some of these accommodations were initiated by a collaborative employee/employer discussion, others were initiated by the employer's perception of safe working conditions in pregnancy, and some accommodations were based on medical recommendations. Participants described supportive and unsupportive employer reactions to requests for accommodations. CONCLUSIONS: Our findings provide novel insights into women's experiences balancing a pregnancy at increased risk for preterm birth with employment obligations. While many women reported positive experiences, the most striking insights came from women who described negative situations that ranged from challenging to potentially unlawful. Many of the findings suggest profound misunderstandings likely exist at the patient, employer and clinical provider level about the laws surrounding employment in pregnancy, safe employment responsibilities during pregnancy, and the range of creative accommodations that often allow for continued workplace productivity even during high risk pregnancy.

OBJECTIVE: Weekly 17-hydroxyprogesterone caproate (17OHP-C) from 16 to 36 weeks' gestation reduces the risk of recurrent spontaneous preterm birth (sPTB). Limited data suggest poor adherence to published guidelines. This study aimed to identify factors associated with 17OHP-C utilization. STUDY DESIGN: This retrospective cohort study included women with a singleton pregnancy who delivered within one academic health system between January 2014 and December 2015. Eligible women had a history of ≥1 singleton sPTB. Primary outcomes were counseling about, receipt of, and adherence to 17OHP-C therapy. Demographic and clinical predictors of the primary outcomes were determined using stepwise logistic regression. RESULTS: Of 410 eligible subjects, 69% (N = 284) were counseled about and 36% (N = 148) received 17OHP-C. Hispanic ethnicity, delay in prenatal care initiation, and a history of prior term births were associated with lower odds of 17OHP-C counseling. Each week delay in prenatal care initiation, Hispanic ethnicity, and each additional week's gestation of the earliest prior sPTB decreased the odds of receiving 17OHP-C. Maternal age and prior term births were associated with adherence. CONCLUSION: Utilization of evidence-based 17OHP-C therapy remains suboptimal: cultural and access-to-care barriers for eligible women may impede efforts to decrease recurrent sPTB rates.

Given the illness and deaths caused by respiratory syncytial virus (RSV) infection during the first year of life, preventing infant RSV infections through maternal vaccination is intriguing. However, little is known about the extent and maternal effects of RSV infection during pregnancy. We describe 3 cases of maternal RSV infection diagnosed at a US center during winter 2014. Case-patient 1 (26 years old, week 33 of gestation) received a diagnosis of RSV infection and required mechanical ventilation. Case-patient 2 (27 years old, week 34 of gestation) received a diagnosis of infection with influenza A(H1N1) virus and RSV and required mechanical ventilation. Case-patient 3 (21 years old, week 32 of gestation) received a diagnosis of group A streptococcus pharyngitis and RSV infection and was monitored as an outpatient. Clarifying the effects of maternal RSV infection could yield valuable insights into potential maternal and fetal benefits of an effective RSV vaccination program.

OBJECTIVE: To evaluate the influence of the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial and the coronavirus disease 2019 (COVID-19) pandemic on racial and ethnic differences in labor induction, pregnancy-associated hypertension, and cesarean delivery among non-Hispanic Black and non-Hispanic White low-risk, first-time pregnancies. METHODS: We conducted an interrupted time series analysis of U.S. birth certificate data from maternal non-Hispanic Black and non-Hispanic White race and ethnicity, first pregnancy, 39 or more weeks of gestation, with no documented contraindication to vaginal delivery or expectant management beyond 39 weeks. We compared the rate of labor induction (primary outcome), pregnancy-associated hypertension, and cesarean delivery during three time periods: pre-ARRIVE (January 1, 2015-July 31, 2018), post-ARRIVE (November 1, 2018-February 29, 2020), and post-COVID-19 (March 1, 2020-December 31, 2021). RESULTS: In the post-ARRIVE period, the rate of labor induction increased in both non-Hispanic White and non-Hispanic Black patients, with no statistically significant difference in the magnitude of increase between the two groups (rate ratio for race [RR race ] 0.98, 95% CI, 0.95-1.02, P =.289). Post-COVID-19, the rate of labor induction increased in non-Hispanic White but not non-Hispanic Black patients. The magnitude of the rate change between non-Hispanic White and non-Hispanic Black patients was significant (RR race 0.95, 95% CI, 0.92-0.99, P =.009). Non-Hispanic Black pregnant people were more likely to have pregnancy-associated hypertension and more often delivered by cesarean at all time periods. CONCLUSION: Changes in obstetric practice after both the ARRIVE trial and the COVID-19 pandemic were not associated with changes in Black-White racial differences in labor induction, cesarean delivery, and pregnancy-associated hypertension.

OBJECTIVE: To describe the prevalence of maternal chronic hypertension (MCH), assess how frequently blood pressure is controlled before pregnancy among those with MCH, and explore management practices for antihypertensive medications (AHM) during the pre-pregnancy and pregnancy periods. DATA SOURCES, STUDY SETTING, AND STUDY DESIGN: We conducted a descriptive observational study using data abstracted from the Veterans Health Administration (VA) inclusive of approximately 11 million Veterans utilizing the VA in fiscal years 2010-2019. DATA COLLECTION/EXTRACTION METHODS: Veterans aged 18-50 were included if they had a diagnosis of chronic hypertension before a documented pregnancy in the VA EMR. We identified chronic hypertension and pregnancy with diagnosis codes and defined uncontrolled blood pressure as ≥140/90 mm Hg on at least one measurement in the year before pregnancy. Sensitivity models were conducted for individuals with at least two blood pressure measurements in the year prior to pregnancy. Multivariable logistic regression explored the association of covariates with recommended and non-recommended AHMs received 0-6 months before pregnancy and during pregnancy. PRINCIPAL FINDINGS: In total, 8% (3767/46,178) of Veterans with a documented pregnancy in VA data had MCH. Among 2750 with MCH meeting inclusion criteria, 60% (n = 1626) had uncontrolled blood pressure on at least one BP reading and 31% (n = 846) had uncontrolled blood pressure on at least two BP readings in the year before pregnancy. For medications, 16% (n = 437) received a non-recommended AHM during pregnancy. Chronic kidney disease (OR = 3.2; 1.6-6.4) and diabetes (OR = 2.3; 1.7-3.0) were most strongly associated with use of a non-recommended AHM during pregnancy. CONCLUSIONS: Interventions are needed to decrease the prevalence of MCH, improve preconception blood pressure control, and ensure optimal pharmacologic antihypertensive management among Veterans of childbearing potential.

Importance: Doulas are trained professionals that provide comprehensive support during the perinatal period. Doula-supported care is associated with improved maternal and infant outcomes including decreased preterm birth, increased breastfeeding initiation, and higher patient satisfaction. In addition, research suggests that doula support is a promising strategy to mitigate racial disparities in maternal and infant health outcomes. Objective: This article reviews doulas' scope of practice, perinatal outcomes associated with doula-assisted care, and their impact on alleviating racial disparities in maternal-infant outcomes. Evidence Acquisition: A literature search using the search engine PubMed was done. The search terms included ([Doula OR doulas OR labor coach] AND [Preterm OR prenatal care OR race OR racial OR racism OR Black OR African American]). Studies had to be written in English. Results: The search resulted 90 articles of which 18 original articles and 16 review articles were reviewed. The literature demonstrates that doula support increases vaginal delivery while decreasing preterm birth and low birth weight. Studies also show that doula support is uniquely effective for Black patients and is a promising strategy to reduce health care inequities. Conclusions and Relevance: Doulas may provide significant perinatal benefit for birthing patients and their infants, with advantages also noted for Black patients. The current article provides an overview of the literature focused on doula support.

Unacceptably high rates of severe maternal morbidity and mortality in the United States and stark racial disparities in outcomes are generating efforts to improve both research capacity and quality improvement in obstetrical care. Comprehensive, high-quality datasets on which to build these efforts are crucial to the success of obstetrical quality improvement efforts. However, existing data sources in obstetrics have notable limitations. Other medical and surgical specialties have addressed similar challenges through the creation of national registries, and we argue that obstetrics must take the same approach to improve outcomes. In this article, we summarized the current availability and limitations of large-scale data in obstetrics research and compared the data with registries developed in other specialties. Moreover, we have outlined the guiding principles for the development of a national obstetrics registry and have proposed future directions.

Adnexal masses in the third trimester of pregnancy may obstruct the pelvic outlet precluding labor induction and vaginal delivery. Expectant versus surgical management of adnexal cysts in pregnancy must carefully weigh maternal-fetal benefits and risks. Simple benign appearing cysts with low likelihood of malignancy may be amenable to percutaneous drainage as a bridge to interval postpartum laparoscopic cystectomy. We demonstrated posterior culdocentesis as a safe, minimally invasive technique to decompress a simple benign appearing left adnexal cyst obstructing the pelvic outlet in the third trimester at the time of labor induction to facilitate vaginal delivery and prevent primary cesarean delivery. Detailed sonographic cyst evaluation and counseling on underlying risk of malignancy must be considered to guide shared decision-making.
RESUMO
Importance: CenteringPregnancy (CP) is a model for group prenatal care associated with improved perinatal outcomes for preterm birth and low birthweight, increased rates of breastfeeding, and higher rates of patient and clinician satisfaction. Objective: The study aims to review the literature related to perinatal outcomes associated with CP, benefits and barriers to implementation, and utility of the model. Evidence: An electronic-based search was performed in PubMed using the search terms "CenteringPregnancy" OR "Centering Pregnancy," revealing 221 articles. Results: The CP model improves patient centeredness, efficiency, and equality in prenatal care. Challenges include administrative buy-in, limited resources, and financial support. Multisite retrospective studies of CP demonstrate improved maternal, neonatal, postpartum, and well-being outcomes, especially for participants from minority backgrounds; however, prospective studies had mixed results. CenteringPregnancy is feasibly implemented with high tenet fidelity in several low- and middle-income settings with improved perinatal outcomes compared with traditional care. Conclusions: CenteringPregnancy is feasible to implement, largely accepted by communities, and shows positive qualitative and quantitative health outcomes. This body of literature supports CP as a potential tool for decreasing racial inequalities in prenatal access, quality of care, and maternal mortality. Further investigation is necessary to inform obstetric clinicians about the potential outcome differences that exist between group and traditional prenatal care.

Clinicians and researchers use published standards to assess and classify the size and growth of the fetus and newborn infant. Fetal growth is slower on average in Black fetuses as compared with White fetuses, and existing standards differ in whether they are race-specific or not. Here, we apply a health equity lens to the topic of fetal and newborn growth assessment by critically appraising two widely available growth standards. We conclude that using race-based standards is not well-justified and could perpetuate or even worsen inequities in perinatal health outcomes. We therefore recommend that neonatal and perinatal providers remove race from the assessment of fetal and newborn size.

Importance: Low-dose aspirin (LDA) is one of the few evidence-based interventions for preventing preeclampsia, which is a leading cause of maternal or fetal morbidity and mortality. Current guidelines recommend LDA based on the presence of risk factors for preeclampsia, but the population-based prevalence of these factors is unknown. Objective: To estimate population-level prevalence of preeclampsia risk factors used in prophylactic LDA guidelines for pregnant patients and the association of these risk factors with reported rates of pregnancy-related hypertension. Design, Setting, and Participants: A retrospective cohort study was conducted using National Center for Health Statistics birth certificate data to describe the frequency of pregnant individuals with moderate to high-risk factors for preeclampsia and pregnancy-related hypertension rates. The study used all birth records in the United States for the 2019 calendar year. Exposures: Documentation of preeclampsia risk factors: multifetal gestation, pregestational diabetes, chronic hypertension (high-risk factors) and nulliparity, a body mass index greater than 30, African American race, a maternal age 35 years or older, an interval of more than 10-years since last birth, and having low socioeconomic status (moderate risk factors). Main Outcomes and Measures: Prevalence of each risk factor alone and in combinations leading to a recommendation for LDA; incidence of pregnancy-related hypertension by risk factor and combinations of risk factors. Results: There were 3â¯695â¯019 pregnancies in 2019, including 528â¯778 with no risk factors, 169â¯540 with 1 or more high-risk factors, and 2â¯996â¯701 with 1 or more moderate-risk factors. The mean (SD) of the cohort was 29.1 (5.8) years. Multifetal gestation was the most common high-risk factor and found in 123â¯995 pregnancies (3.4%), and low socioeconomic status was the most common moderate-risk factor and present in 1â¯732â¯729 pregnancies (46.9%). Based on 2021 criteria (a single high- or moderate-risk factors for preeclampsia), 3â¯166â¯241 pregnant patients (85.7%) were eligible for LDA. The incidence of pregnancy-related hypertension increased with the number of moderate-risk factors. The 2021 guidelines suggest considering or recommend LDA in 92.3% of pregnancies diagnosed with pregnancy-related hypertension. Conclusions and Relevance: These data support the recently published guidelines and suggest further simplified guidelines recommending LDA to patients with any single moderate-risk factors.

Importance: Group B Streptococcus (GBS) is a common pathogen with an effective treatment. However, it remains a significant cause of neonatal sepsis, morbidity, and mortality. The screening and management of this infection are some of the first concepts learned during medical training in obstetrics. However, effective screening and evidence-based management of GBS are nuanced with many critical caveats. Objective: The objectives of this review are to discuss the essential aspects of GBS screening and management and to highlight recent changes to recommendations and guidelines. Evidence Acquisition: Original research articles, review articles, and guidelines on GBS were reviewed. Results: The following recommendations are based on review of the evidence and professional society guidelines. Screening for GBS should occur between 36 weeks and the end of the 37th week. The culture swab should go 2 cm into the vagina and 1 cm into the anus. Patients can perform their own swabs as well. Penicillin allergy testing has been shown to be safe in pregnancy. Patients with GBS in the urine should be treated at term with antibiotic prophylaxis, independent of the colony count of the culture. Patients who are GBS-positive with preterm and prelabor rupture of membranes after 34 weeks are not candidates for expectant management, as this population has higher rates of neonatal infectious complications. Patients with a history of GBS colonization in prior pregnancy who are GBS-unknown in this current pregnancy and present with labor should receive intrapartum prophylaxis. Work on the GBS vaccine continues. Conclusions: Although all of the efforts and focus on neonatal early-onset GBS infection have led to lower rates of disease, GBS still remains a major cause of neonatal morbidity and mortality requiring continued vigilance from obstetric providers.
