Background The purpose of this study was to estimate prevalence of asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among patients admitted to obstetric inpatient units throughout the United States as detected by universal screening. We sought to describe the relationship between obstetric inpatient asymptomatic infection rates and publicly available surrounding community infection rates. Methods A cross-sectional study in which medical centers reported rates of positive SARS-CoV-2 testing in asymptomatic pregnant and immediate postpartum patients over a 1–3-month time span in 2020. Publicly reported SARS-CoV-2 case rates from the relevant county and state for each center were collected from the COVID Act Now dashboard and the COVID Tracking Project for correlation analysis. Results Data were collected from 9 health centers, encompassing 18 hospitals. Participating health centers were located in Alabama, California, Illinois, Louisiana, New Jersey, North Carolina, Pennsylvania, Rhode Island, Utah, and Washington State. Each hospital had an active policy for universal SARS-CoV-2 testing on obstetric inpatient units. A total of 10 147 SARS-CoV-2 tests were administered, of which 124 were positive (1.2%). Positivity rates varied by site, ranging from 0–3.2%. While SARS-CoV-2 infection rates were lower in asymptomatic obstetric inpatient groups than the surrounding communities, there was a positive correlation between positivity rates in obstetric inpatient units and their surrounding county (P=.003, r=.782) and state (P=.007, r=.708). Conclusions Given the correlation between community and obstetric inpatient rates, the necessity of SARS-CoV-2–related healthcare resource utilization in obstetric inpatient units may be best informed by surrounding community infection rates., There was a significant positive correlation between SARS-CoV-2 positivity rates in obstetric inpatient units and their surrounding county and state. Healthcare resource utilization related to SARS-CoV-2 testing in obstetric inpatient units may be best informed by surrounding community infection rates.

Limited data are available on the performance of SARS-CoV-2 antibody assays and data collected during pregnancy vary widely. The objective of this study was to estimate the seroprevalence of antibodies against SARS-CoV-2 in pregnant individuals in Rhode Island and to evaluate whether the prevalence differed by month of collection, age, county of residence, or economic status as estimated by zip code.Pre-pandemic (2019) and early pandemic (2020) serum samples, collected for prenatal screening between 15 and 22 weeks of gestation, were analyzed utilizing two SARS-CoV-2 immunoglobulin G (IgG) automated assays that targeted the viral nucleocapsid (anti-N) or spike (anti-S) receptor binding domain proteins.Among 756 pre-pandemic samples, one anti-S IgG and 13 anti-N IgG were identified. No samples were positive for both. Among 787 pandemic specimens, 16 (2.03%) were positive for both anti-N IgG and anti-S IgG. When stratified by month of collection, there was a significant increase in seropositivity rate (When a positive result was defined as both anti-N IgG and anti-S IgG, false positives were unlikely. Based on this methodology, serology could be utilized to monitor infection trends during pregnancy.

Objectives To develop and internally validate risk prediction models identifying women at risk for cardiovascular severe maternal morbidity (CSMM). Design A retrospective cohort study. Setting An obstetric teaching hospital between 2007 and 2017. Population A total of 89 681 delivery hospitalisations. Methods We created and evaluated two models, one predicting CSMM at delivery (delivery model) and the other predicting CSMM postpartum following discharge from delivery hospitalisation (postpartum CSMM). We assessed model discrimination and calibration and used bootstrapping for internal validation. Main outcome measures Cardiovascular severe maternal morbidity comprised the following confirmed conditions: pulmonary oedema/acute heart failure, myocardial infarction, aneurysm, cardiac arrest/ventricular fibrillation, heart failure/arrest during surgery or procedure, cerebrovascular disorders, cardiogenic shock, conversion of cardiac rhythm and difficult-to-control severe hypertension. Results The delivery model contained 11 variables and 3 interaction terms. The strongest predictors were gestational hypertension, chronic hypertension, multiple gestation, cardiac lesions or valvular heart disease, maternal age ≥40 years and history of poor pregnancy outcome. The postpartum model comprised eight variables. The strongest predictors were severe pre-eclampsia, non-Hispanic Black race/ethnicity, chronic hypertension, gestational hypertension, non-severe pre-eclampsia and maternal age ≥40 years at delivery. The delivery and postpartum models had an area under the receiver operating characteristic curve of 0.87 (95% CI 0.85-0.89) and 0.85 (95% CI 0.80-0.90), respectively. Both models were adequately calibrated and performed well on internal validation. Conclusions These tools may help providers to identify women at highest risk of CSMM and enable future prevention measures. Tweetable abstract Risk assessment tools for cardiovascular severe maternal morbidity were developed and internally validated.

Women with preeclampsia are at increased short-term risk of adverse cardiovascular outcomes during pregnancy and the early postpartum period. We aimed to develop and internally validate a risk assessment tool to predict acute cardiovascular morbidity in preeclampsia.The study was conducted at an academic obstetrics hospital. Participants with preeclampsia at delivery from 2007 to 2017 were included. A model to predict acute cardiovascular morbidity at delivery and within 6 weeks after delivery was developed and evaluated. The primary composite outcome included pulmonary edema/acute heart failure, myocardial infarction, aneurysm, cardiac arrest/ventricular fibrillation, heart failure/arrest during surgery or procedure, cerebrovascular disorders, cardiogenic shock, conversion of cardiac rhythm, and difficult-to-control severe hypertension. We assessed model discrimination and calibration. We used bootstrapping for internal validation.A total of 4171 participants with preeclampsia were included. The final model comprised 8 variables. Predictors positively associated with acute cardiovascular morbidity (presented as odds ratio with 95% confidence interval) were: gestational age at delivery (20-36 weeks: 5.36 [3.67-7.82]; 37-38 weeks: 1.75 [1.16-2.64]), maternal age (≥ 40 years: 1.65 [1.00-2.72]; 35-39 years: 1.49 [1.07-2.09]), and previous caesarean delivery (1.47 [1.01-2.13]). The model had an area under the receiver operating characteristic curve of 0.72 (95% CI 0.69-0.74). Moreover, it was adequately calibrated and performed well on internal validation.This risk prediction tool identified women with preeclampsia at highest risk of acute cardiovascular morbidity. If externally validated, this tool may facilitate early interventions aimed at preventing adverse cardiovascular outcomes in pregnancy and postpartum.

In March 2020, the National Institutes of Health COVID-19 Treatment Guidelines Panel began developing evidence-based guidelines for the treatment of COVID-19. In this article, Panel members summarize some of the lessons learned from their first year of work., The development of the National Institutes of Health (NIH) COVID-19 Treatment Guidelines began in March 2020 in response to a request from the White House Coronavirus Task Force. Within 4 days of the request, the NIH COVID-19 Treatment Guidelines Panel was established and the first meeting took place (virtually—as did subsequent meetings). The Panel comprises 57 individuals representing 6 governmental agencies, 11 professional societies, and 33 medical centers, plus 2 community members, who have worked together to create and frequently update the guidelines on the basis of evidence from the most recent clinical studies available. The initial version of the guidelines was completed within 2 weeks and posted online on 21 April 2020. Initially, sparse evidence was available to guide COVID-19 treatment recommendations. However, treatment data rapidly accrued based on results from clinical studies that used various study designs and evaluated different therapeutic agents and approaches. Data have continued to evolve at a rapid pace, leading to 24 revisions and updates of the guidelines in the first year. This process has provided important lessons for responding to an unprecedented public health emergency: Providers and stakeholders are eager to access credible, current treatment guidelines; governmental agencies, professional societies, and health care leaders can work together effectively and expeditiously; panelists from various disciplines, including biostatistics, are important for quickly developing well-informed recommendations; well-powered randomized clinical trials continue to provide the most compelling evidence to guide treatment recommendations; treatment recommendations need to be developed in a confidential setting free from external pressures; development of a user-friendly, web-based format for communicating with health care providers requires substantial administrative support; and frequent updates are necessary as clinical evidence rapidly emerges.

Background Adenovirus infection is usually mild in presentation. However during pregnancy, the course can be more severe. Case A 21-year-old woman in her second pregnancy presented with abdominal pain, vomiting, and fevers at 34 weeks and 4 days of gestation. Her respiratory pathogen panel on nasopharyngeal secretions was positive for adenovirus. Electrolytes were notable for hypomagnesaemia and persistent hypokalemia (nadir of 2.6 mmol/L) despite repletion but otherwise unremarkable. During her course, she developed rhabdomyolysis. During routine fetal monitoring at 35 weeks and 6 days of gestation, prolonged fetal bradycardia was identified, and an emergency caesarean delivery was performed. The infant had no clinical or laboratory evidence of adenovirus infection. The patient had a protracted clinical course but recovered with supportive care. Conclusion Adenovirus can present with severe complications in a pregnant woman including hypokalemia and rhabdomyolysis. The mainstay of treatment is supportive care and monitoring of electrolyte abnormalities and renal function.

BACKGROUND Following the destruction of pharmaceutical production facilities in Puerto Rico by Hurricane Maria in September 2017, a shortage of small-volume bags of sterile intravenous fluid for infusion led to a decreased ability to administer intravenous azithromycin and ampicillin efficiently for use in the treatment of patients with preterm premature rupture of membranes. OBJECTIVE This study aimed to assess pregnancy latency after preterm premature rupture of membranes following treatment with oral-only antibiotics compared with treatment with intravenous antibiotics followed by oral antibiotics. STUDY DESIGN This is a retrospective historic control study comparing women with preterm premature rupture of membranes who were initiated on a 7-day oral-only regimen of azithromycin and amoxicillin (modified regimen) during a 12-month period beginning December 2017 (during which time there was a shortage of small-volume bags of intravenous fluid) to women with preterm premature rupture of membranes who were initiated on a 2-day regimen of intravenous ampicillin and azithromycin followed by 5 days of oral amoxicillin and azithromycin (standard regimen) from December 2016 to December 2018. Women were included in the study if they were diagnosed with preterm premature rupture of membranes at

Background Cardiovascular severe maternal morbidity (CSMM) is rising and has become the leading cause of maternal mortality. Research using administrative data sets may allow for better understanding of this critical group of diseases. Objective To validate a composite variable of CSMM for use in epidemiologic studies. Methods We analysed delivery hospitalisations at an obstetric teaching hospital from 2007 to 2017. We utilised a subset of indicators developed by the Centers for Disease Control and Prevention based on ICD codes to form the composite variable for CSMM. Two expert clinicians manually reviewed all qualifying events using a standardised tool to determine whether these represented true CSMM events. Additionally, we estimated the number of CSMM cases among delivery hospitalisations without qualifying ICD codes by manually reviewing all hospitalisations with severe preeclampsia, a population at high risk of CSMM, and a random sample of 1000 hospitalisations without severe preeclampsia. We estimated validity of the composite variable. Results Among 91 355 admissions for delivery, we captured 113 potential CSMM cases using qualifying ICD codes. Of these, 65 (57.5%) were true CSMM cases. Indicators for acute myocardial infarction, cardiac arrest, and cardioversion had the highest true-positive rates (100% for all). We found an additional 70 CSMM cases in the 2102 admissions with severe preeclampsia and a single CSMM case in the random sample. Assuming a rate of 1 CSMM case per 1000 deliveries in the remaining cohort, the composite variable had a positive predictive value of 57.5% (95% CI 47,9, 66.8), a negative predictive value of 99.8% (95% CI 99.8, 99.9), a sensitivity of 29.0% (95% CI 23.2, 35.4), and a specificity of 100% (95% CI 99.9, 100.0). Conclusion A novel composite variable for CSMM had reasonable PPV but limited sensitivity. This composite variable may enable epidemiologic studies geared towards reducing maternal morbidity and mortality.

In the United States, sexually transmitted diseases due toChlamydia trachomatisandNeisseria gonorrhoeaecontinue to be a major public health burden. Screening of extragenital sites including the oropharynx and rectum is an emerging practice based on recent studies highlighting the prevalence of infection at these sites. We reviewed studies reporting the prevalence of extragenital infections in women, men who have sex with men (MSM), and men who have sex only with women (MSW), including distribution by anatomical site. Among women, prevalence was found to be 0.6–35.8% for rectal gonorrhea (median reported prevalence 1.9%), 0–29.6% for pharyngeal gonorrhea (median 2.1%), 2.0–77.3% for rectal chlamydia (median 8.7%), and 0.2–3.2% for pharyngeal chlamydia (median 1.7%). Among MSM, prevalence was found to be 0.2–24.0% for rectal gonorrhea (median 5.9%), 0.5–16.5% for pharyngeal gonorrhea (median 4.6%), 2.1–23.0% for rectal chlamydia (median 8.9%), and 0–3.6% for pharyngeal chlamydia (median 1.7%). Among MSW, the prevalence was found to be 0–5.7% for rectal gonorrhea (median 3.4%), 0.4–15.5% for pharyngeal gonorrhea (median 2.2%), 0–11.8% for rectal chlamydia (median 7.7%), and 0–22.0% for pharyngeal chlamydia (median 1.6%). Extragenital infections are often asymptomatic and found in the absence of reported risk behaviors, such as receptive anal and oral intercourse. We discuss current clinical recommendations and future directions for research.

Background Prevention of mother to child transmission (PMTCT) of Human Immunodeficiency Virus (HIV) requires a comprehensive approach and understanding the cultural backgrounds of pregnant women living with HIV (PWLH). In Rhode Island (RI), 70% of women newly diagnosed with HIV are foreign-born (FB) despite only representing 14% of RI’s population. Understanding the similarities and differences of pregnancy characteristics and engagement in postpartum HIV care between United States born (USB) and FB women is needed to ensure PWLH remain engaged in care and that appropriate resources are provided to all women with HIV in our state to maintain successful PMTCT of HIV. Methods A retrospective review of pregnant women living with HIV and their HIV-exposed infants evaluated in our hospital system were analyzed from 2012-2019. Clinical data were derived from medical records. Association between country of origin and sociodemographic, clinical, or lab variables were evaluated using chi-square test. Results A total of 72 pregnancies in 64 PWLH were included. Median # of pregnancies were 9 per year, median age at delivery 33 years, 54% of PWLH Black or African American, 33% Hispanic; 67.1% FB, most (56%) from Sub-Saharan Africa. Sixty-one % (n=42) with detectable (> 20 copies/mL) viral load (VL) during pregnancy, 23% (n=15) at delivery, only 1 VL > 200 at delivery. Pregnancy complications seen in 51%; 60% delivered vaginally; most (74%) at term. Engagement in postpartum HIV care declined from 71% at 6 months to 37% at 24 months. There was also decline in engagement in HIV care for the HIV exposed infants- 89% presented to the initial visit their children, from 89% attending the initial visit to 69% attending their last. DCYF involvement was more likely to occur in USB women compared to FB (P < 0.05). Other comparisons between FB & USB women including adherence to care were insignificant. Conclusion USB PWLH are at higher risk of DCYF involvement compared to FB women. Investigation into this disparity is warranted, given the cultural and language differences between groups. Additional research to determine barriers to long-term postpartum follow up for women and their infants is urgently needed. Disclosures All Authors: No reported disclosures

Globally, infectious diseases often disproportionately affect women, and have implications for the health of future generations. The human immunodeficiency virus (HIV), tuberculosis, malaria, and schistosomiasis are four such pathogens. Infection with these organisms has a broad impact on maternal child health in many areas of the developing world, and global initiatives to control these diseases will significantly improve the health of generations to come.

The reduction of human immunodeficiency virus (HIV) transmission from mother to child is one of the success stories of modern medicine and public health. In the developed world, with universal HIV counseling and testing, antiretroviral prophylaxis, scheduled Caesarean delivery if indicated, and avoidance of breastfeeding, HIV transmission from mother to infant can be

Many physiological and anatomical changes of pregnancy affect the respiratory system. These changes often affect the presentation and management of the various respiratory illnesses in pregnancy. This article focuses on several important respiratory issues in pregnancy. The management of asthma, one of the most common chronic illnesses in pregnancy, remains largely unchanged compared to the nonpregnant state. Infectious respiratory illness, including pneumonia and tuberculosis, are similarly managed in pregnancy with antibiotics, although special attention may be needed for antibiotic choices with more pregnancy safety data. When mechanical ventilation is necessary, consideration should be given to the maternal hemodynamics of pregnancy and fetal oxygenation. Maintaining maternal oxygen saturation above 95% is recommended to sustain optimal fetal oxygenation. Cigarette smoking has known risks in pregnancy, and current practice guidelines recommend offering cognitive and pharmacologic interventions to pregnant women to assist in smoking cessation.

With universal HIV testing prior to or early in pregnancy, early and effective antiretroviral therapy for all pregnant women, scheduled cesarean delivery if indicated, and antiretroviral therapy for the infant, as well as effective pre- and postconception counseling, HIV-infected women can have healthy and successful pregnancies.

Sexual exposure to STDs including HIV and hepatitis is common. Sexual assault is also prevalent and should be screened for in a patient presenting for medical care after potential sexual exposure to STDs. Primary care providers should be familiar with current recommendations for STD prophylaxis and treatment after sexual exposure to STDs, and be aware that HIV postexposure prophylaxis is effective and available if indicated after sexual exposure to HIV. Providers should also be aware of the need for prompt referal for evaluation and medical care of the adult patient after a sexual assault.
