EngagINg the COmmunity to Reduce Preterm birth via Adherence To an Individualized Prematurity Prevention Plan (INCORPorATe IP3): intervention development and future pilot study design

OBJECTIVE

Non-Hispanic Black birthing individuals are at increased risk of preterm birth compared to other racial and ethnic groups. In our clinical setting, we offer a tailored package of recommendations to reduce the risk of preterm birth known as an individualized prematurity prevention plan (IP3). Patient-centered, community engaged interventions that address patient-perceived barriers to preterm birth prevention are urgently needed.

MATERIALS AND METHODS

We engaged a group of stakeholders to develop a mutli-level (patient-centered and community-involved) intervention that will increase adherence to an individualized prematurity prevention plan (IP3) by addressing barriers identified during our prior qualitative studies.

RESULTS

The intervention includes trained doulas from a community-led, Black owned doula group. The doulas will moderate group prenatal social support sessions. In between the group sessions, participants will be encouraged to continue interacting with one another and the doulas using a private Facebook™ group page. We will pilot test the intervention in a cohort of pregnant, self-identified non-Hispanic Black patients with a history of prior preterm birth.

CONCLUSION

We present a novel, patient-centered, community engaged intervention to reduce preterm birth in high-risk non-Hispanic Black birthing individuals. If the intervention is feasible based on the pilot study findings, we anticipate conducting an appropriately powered study to determine whether the intervention achieves our goal of reducing preterm birth.

Improving Clinician's Knowledge and Comfort with Prenatal and Postpartum Employment Laws: A Pilot Intervention

BACKGROUND

It is common for pregnant people in the United States to continue to work throughout their pregnancy. Pregnant people may need leave time or other accommodations to continue working safely. It is imperative that obstetric providers are knowledgeable regarding laws that govern the prenatal and postpartum period to provide appropriate counseling and medical documentation in support of requests for leave time and workplace accommodations.

METHODS

We created a virtual training for obstetric clinicians regarding employment considerations in the prenatal and postpartum period. The training details the federal laws that govern this period, when and how to request reasonable accommodations from an employer, and provides resources for clinicians to use when they believe pregnancy-related discrimination has occurred. We conducted pretest and post-test surveys to assess change in knowledge about employment laws and comfort with counseling patients.

RESULTS

There were 61 clinicians who completed the training (50.4% response rate). The majority (88%, n = 54) of respondents reported no prior formal training about employment laws in pregnancy. On the pretraining self-assessment, >93% (n = 57) of participants felt they had minimal or very minimal knowledge regarding lactation and pregnancy-related accommodations, compared with >91% (n = 55) feeling very or somewhat knowledgeable after the training. The mean percent correct on the knowledge assessment increased from 55% to 67% on the pre- and post-test knowledge questions, respectively.

DISCUSSION

Our findings suggest an on-demand virtual training can improve knowledge and comfort for obstetric clinicians about federal employment laws in pregnancy and postpartum.

Compassionate Use of Remdesivir in Pregnant Women with Severe Covid-19

Background

Remdesivir is efficacious for severe coronavirus disease 2019 (COVID-19) in adults, but data in pregnant women are limited. We describe outcomes in the first 86 pregnant women with severe COVID-19 who were treated with remdesivir.

Methods

The reported data span 21 March to 16 June 2020 for hospitalized pregnant women with polymerase chain reaction–confirmed severe acute respiratory syndrome coronavirus 2 infection and room air oxygen saturation ≤94% whose clinicians requested remdesivir through the compassionate use program. The intended remdesivir treatment course was 10 days (200 mg on day 1, followed by 100 mg for days 2–10, given intravenously).

Results

Nineteen of 86 women delivered before their first dose and were reclassified as immediate “postpartum” (median postpartum day 1 [range, 0–3]). At baseline, 40% of pregnant women (median gestational age, 28 weeks) required invasive ventilation, in contrast to 95% of postpartum women (median gestational age at delivery 30 weeks). By day 28 of follow-up, the level of oxygen requirement decreased in 96% and 89% of pregnant and postpartum women, respectively. Among pregnant women, 93% of those on mechanical ventilation were extubated, 93% recovered, and 90% were discharged. Among postpartum women, 89% were extubated, 89% recovered, and 84% were discharged. Remdesivir was well tolerated, with a low incidence of serious adverse events (AEs) (16%). Most AEs were related to pregnancy and underlying disease; most laboratory abnormalities were grade 1 or 2. There was 1 maternal death attributed to underlying disease and no neonatal deaths.

Conclusions

Among 86 pregnant and postpartum women with severe COVID-19 who received compassionate-use remdesivir, recovery rates were high, with a low rate of serious AEs.

The Project Baseline Health Study: a step towards a broader mission to map human health

The Project Baseline Health Study (PBHS) was launched to map human health through a comprehensive understanding of both the health of an individual and how it relates to the broader population. The study will contribute to the creation of a biomedical information system that accounts for the highly complex interplay of biological, behavioral, environmental, and social systems. The PBHS is a prospective, multicenter, longitudinal cohort study that aims to enroll thousands of participants with diverse backgrounds who are representative of the entire health spectrum. Enrolled participants will be evaluated serially using clinical, molecular, imaging, sensor, self-reported, behavioral, psychological, environmental, and other health-related measurements. An initial deeply phenotyped cohort will inform the development of a large, expanded virtual cohort. The PBHS will contribute to precision health and medicine by integrating state of the art testing, longitudinal monitoring and participant engagement, and by contributing to the development of an improved platform for data sharing and analysis.

Beyond the Window: Patient Characteristics and Geographic Locations Associated with Late Prenatal Care in Women Eligible for 17-P Preterm Birth Prevention

INTRODUCTION

To reduce the risk of recurrence, women with a history of spontaneous preterm birth (PTB) are recommended to receive 17-hydroxyprogesterone caproate (17-P) injections starting by the 20th week of pregnancy. In women eligible for 17-P, we aimed to identify patient factors and geospatial locations associated with increased risk of presentation beyond 20 weeks gestation.

METHODS

We conducted a secondary analysis of a retrospective cohort study including all women meeting criteria for 17-P within a single academic medical center over a 2-year period. We compared early (< 20 6/7 weeks) with late (> 21 weeks) presenters via demographics, social history, and index pregnancy outcomes using standard and Bayesian statistical models. Geospatial mapping was performed to determine residential areas with high risk for late presentation.

RESULTS

Geocoded address data was available for 351 women in whom the mean gestational age at first visit was 14.9 weeks, and 63 of whom were late presenters (17.9%). Younger maternal age, current smoking, and lack of health insurance were predictors of late presentation with greater than 95% probability. Hispanic ethnicity and black race were associated with higher odds of late presentation with 87 and 69% probability, respectively. The area with the latest gestational age at presentation was located within central Durham City and to the northeast.

DISCUSSION

Our study identified patient-level risk factors and geographic locations associated with presentation beyond the recommend window for 17-P initiation. These findings suggest an urgent need for intervention to improve early prenatal care initiation and a target location where such interventions will be most impactful.

Psychosocial Stress and Preterm Birth: The Impact of Parity and Race

Objectives Studies examining risk factors for preterm birth (PTB) such as psychosocial stress are often focused on women with a history of PTB; however, most preterm babies are born to women with no history of preterm birth. Our objective was to determine if the relationship between psychosocial stress and PTB is altered by parity. Non-Hispanic black (NHB) women have increased psychosocial stress and PTB; therefore, we further aimed to determine if race alters the relationship between psychosocial stress, parity, and PTB. Methods We performed a secondary analysis of the Healthy Pregnancy, Healthy Baby Study comparing pregnant women who were primiparous (first pregnancy), multiparous with history of preterm birth, or multiparous with history of term birth. Perceived stress, perceived racism, interpersonal support, John Henryism and self-efficacy were measured using validated instruments. Logistic regression was used to model the effect of psychosocial stress on PTB stratified by parity and race. Results The analysis entire cohort included 1606 subjects, 426 were primiparous, 268 had a history of presterm birth, and 912 had a history of term birth. In women with a history of term birth, higher self-efficacy was associated with lower odds of spontaneous PTB, and this association was amplified in NHB women. In women with a history of spontaneous PTB, John Henryism Active Coping was associated with lower odds of spontaneous PTB in the index pregnancy. Conclusions for Practice The relationship between psychosocial stress and PTB may be mediated by parity and race.

Perinatal western-type diet and associated gestational weight gain alter postpartum maternal mood

INTRODUCTION

The role of perinatal diet in postpartum maternal mood disorders, including depression and anxiety, remains unclear. We investigated whether perinatal consumption of a Western-type diet (high in fat and branched-chain amino acids [BCAA]) and associated gestational weight gain (GWG) cause serotonin dysregulation in the central nervous system (CNS), resulting in postpartum depression and anxiety (PPD/A).

METHODS

Mouse dams were fed one of four diets (high-fat/high BCAA, low-fat/high BCAA, high-fat, and low-fat) prior to mating and throughout gestation and lactation. Postpartum behavioral assessments were conducted, and plasma and brain tissues assayed. To evaluate potential clinical utility, we conducted preliminary human studies using data from an extant sample of 17 primiparous women with high GWG, comparing across self-reported postpartum mood symptoms using the Edinburgh Postnatal Depression Scale (EPDS) for percent GWG and plasma amino acid levels.

RESULTS

Mouse dams fed the high-fat/high BCAA diet gained more weight per kcal consumed, and BCAA-supplemented dams lost weight more slowly postpartum. Dams on BCAA-supplemented diets exhibited increased PPD/A-like behavior, decreased dopaminergic function, and decreased plasma tyrosine and histidine levels when assessed on postnatal day (P)8. Preliminary human data showed that GWG accounted for 29% of the variance in EPDS scores. Histidine was also lower in women with higher EPDS scores.

CONCLUSIONS

These findings highlight the role of perinatal diet and excess GWG in the development of postpartum mood disorders.

Neighborhood Disadvantage is Associated with High Cytomegalovirus Seroprevalence in Pregnancy

BACKGROUND

Cytomegalovirus (CMV) is the most common infectious cause of fetal malformations and childhood hearing loss. CMV is more common among socially disadvantaged groups, and geographically clusters in poor communities. The Area Deprivation Index (ADI) is a neighborhood-level index derived from census data that reflects material disadvantage.

METHODS

We performed a geospatial analysis to determine if ADI predicts the local odds of CMV seropositivity. We analyzed a dataset of 3527 women who had been tested for CMV antibodies during pregnancy. We used generalized additive models to analyze the spatial distribution of CMV seropositivity. Adjusted models included individual-level age and race and neighborhood-level ADI.

RESULTS

Our dataset included 1955 CMV seropositive women, 1549 who were seronegative, and 23 with recent CMV infection based on low avidity CMV antibodies. High ADI percentiles, representing greater neighborhood poverty, were significantly associated with the nonwhite race (48 vs. 22, p < 0.001) and CMV seropositivity (39 vs. 28, p < 0.001). Our unadjusted spatial models identified clustering of high CMV odds in poor, urban neighborhoods and clustering of low CMV odds in more affluent suburbs (local odds ratio 0.41 to 1.90). Adjustment for both individual race and neighborhood ADI largely eliminated this spatial variability. ADI remained a significant predictor of local CMV seroprevalence even after adjusting for individual race.

CONCLUSIONS

Neighborhood-level poverty as measured by the ADI is a race-independent predictor of local CMV seroprevalence among pregnant women.

Pregnancy after treatment for cervical cancer precursor lesions in a retrospective matched cohort

Objective

To determine whether treatments for precancerous cervical lesions were associated with lower pregnancy rates compared to rates in unexposed women and women who had a diagnostic cervical biopsy or colposcopy.

Design

Matched, retrospective cohort study.

Setting

Kaiser Permanente Northwest (KPNW), an integrated healthcare delivery system in Oregon and Washington.

Patients

Women 14 to 53 years old with KPNW enrollment during the period 1998 through 2009.

Main Outcome Measure

Pregnancy after exposure or index date. Pregnancy was defined using a validated algorithm and electronic medical records data.

Results

We observed 570 pregnancies following cervical treatment in 4,137 women, 1,533 pregnancies following a diagnostic procedure in 13,767 women, and 7,436 pregnancies in a frequency-matched sample of 81,435 women unexposed to treatment or diagnostic procedures. After adjusting for age and contraceptive use, we observed a higher rate of pregnancies in the treatment group compared to unexposed women (hazard ratio (HR) = 1.42, 95% confidence interval (CI): 1.30–1.55), but no difference in pregnancy rates between the treatment and diagnostic procedure groups (HR = 1.03, 95% CI: 0.93–1.13).

Conclusions

No adverse effects of cervical procedures on subsequent rates of pregnancy were observed in this cohort with up to twelve years of follow-up time.

Representation of women and pregnant women in HIV research: a limited systematic review

BACKGROUND

HIV-related outcomes may be affected by biological sex and by pregnancy. Including women in general and pregnant women in particular in HIV-related research is important for generalizability of findings.

OBJECTIVE

To characterize representation of pregnant and non-pregnant women in HIV-related research conducted in general populations.

DATA SOURCES

All HIV-related articles published in fifteen journals from January to March of 2011. We selected the top five journals by 2010 impact factor, in internal medicine, infectious diseases, and HIV/AIDS.

STUDY ELIGIBILITY CRITERIA

HIV-related studies reporting original research on questions applicable to both men and women of reproductive age were considered; studies were excluded if they did not include individual-level patient data.

STUDY APPRAISAL AND SYNTHESIS METHODS

Articles were doubly reviewed and abstracted; discrepancies were resolved through consensus. We recorded proportion of female study participants, whether pregnant women were included or excluded, and other key factors.

RESULTS

In total, 2014 articles were published during this period. After screening, 259 articles were included as original HIV-related research reporting individual-level data; of these, 226 were determined to be articles relevant to both men and women of reproductive age. In these articles, women were adequately represented within geographic region. The vast majority of published articles, 183/226 (81%), did not mention pregnancy (or related issues); still fewer included pregnant women (n=33), reported numbers of pregnant women (n=19), or analyzed using pregnancy status (n=9).

LIMITATIONS

Data were missing for some key variables, including pregnancy. The time period over which published works were evaluated was relatively short.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

The under-reporting and inattention to pregnancy in the HIV literature may reduce policy-makers' ability to set evidence-based policy around HIV/AIDS care for pregnant women and women of child-bearing age.
