Brexanolone Treatment in a Real-World Patient Population: A Case Series and Pilot Feasibility Study of Precision Neuroimaging.

PURPOSE/BACKGROUND: Brexanolone is approved for postpartum depression (PPD) by the United States Food and Drug Administration. Brexanolone has outperformed placebo in clinical trials, but less is known about the efficacy in real-world patients with complex social and medical histories. Furthermore, the impact of brexanolone on large-scale brain systems such as changes in functional connectivity (FC) is unknown. METHODS/PROCEDURES: We tracked changes in depressive symptoms across a diverse group of patients who received brexanolone at a large medical center. Edinburgh Postnatal Depression Scale (EPDS) scores were collected through chart review for 17 patients immediately prior to infusion through approximately 1 year postinfusion. In 2 participants, we performed precision functional neuroimaging (pfMRI), including before and after treatment in 1 patient. pfMRI collects many hours of data in individuals for precision medicine applications and was performed to assess the feasibility of investigating changes in FC with brexanolone. FINDINGS/RESULTS: The mean EPDS score immediately postinfusion was significantly lower than the mean preinfusion score (mean change [95% CI]: 10.76 [7.11-14.40], t (15) = 6.29, P < 0.0001). The mean EPDS score stayed significantly lower at 1 week (mean difference [95% CI]: 9.50 [5.23-13.76], t (11) = 4.90, P = 0.0005) and 3 months (mean difference [95% CI]: 9.99 [4.71-15.27], t (6) = 4.63, P = 0.0036) postinfusion. Widespread changes in FC followed infusion, which correlated with EPDS scores. IMPLICATIONS/CONCLUSIONS: Brexanolone is a successful treatment for PPD in the clinical setting. In conjunction with routine clinical care, brexanolone was linked to a reduction in symptoms lasting at least 3 months. pfMRI is feasible in postpartum patients receiving brexanolone and has the potential to elucidate individual-specific mechanisms of action.

Pharmacotherapy for opioid use disorder in pregnancy.

PURPOSE OF REVIEW: Opioid use disorder (OUD) in pregnancy has significantly increased in the last decade, impacting 8.2 per 1000 deliveries. OUD carries significant risk of morbidity and mortality for both the birthing person and neonate, but outcomes for both are improved with opioid agonist treatment (OAT). Here, we describe the recommended forms of OAT in pregnancy, updates to the literature, and alternate OAT strategies, and share practical peripartum considerations for patients on OAT. RECENT FINDINGS: Recent studies comparing buprenorphine and methadone have reaffirmed previous findings that buprenorphine is associated with superior outcomes for the neonate, without clear differences in morbidity or mortality for the birthing person. Optimal initiation and dosing of OAT remains unclear, with several recent studies evaluating methods of initiation, as well as a potential role for higher and more rapid dosing in the fentanyl era. Alternative products such as buprenorphine-naloxone and extended-release buprenorphine are of significant research interest, though randomized prospective data are not yet available. SUMMARY: Buprenorphine and methadone are standard of care for treatment of OUD during pregnancy, and multiple patient factors impact the optimal choice. Insufficient data exist to recommend alternative agents as a primary strategy currently. All patients with OUD in pregnancy should be counseled regarding OAT. VIDEO: http://links.lww.com/COOG/A94.

The Association between Mode of Transportation Support and Research Study Visit Attendance among Pregnant Patients.

OBJECTIVE: This study aimed to examine the association between transportation assistance and study visits, and explore differences by transportation modality. STUDY DESIGN: This was a secondary analysis of prospective cohort study. We identified patients requesting transportation support for research ultrasound visits and identified controls (1:2 ratio) who did not request support matched for age, race, and insurance type. Conditional logistic regression examined the association between transportation support and mode of transportation with study visit attendance. RESULTS: Transportation support was requested by 57/1,184 (4.8%) participants. Participants that requested transportation support were three times more likely to attend visits than their matched controls (adjusted odds ratio [aOR] = 3.16, 95% confidence interval [CI]: 1.76-5.68). Among visits with transportation support, those supported by a ridesharing service had five-fold higher odds of attendance than visits supported with taxi service (aOR = 5.06, 95% CI: 1.50-16.98). CONCLUSION: Transportation support, especially a ridesharing service, is associated with improved attendance at research study visits in a sample of predominantly low-income, Black, pregnant participants. Implementing transportation support may be a promising strategy to improve engagement in research studies. KEY POINTS: · Participants utilizing transportation assistance were more likely to attend study appointments.. · Participants using ridesharing had higher likelihood of attendance than those using taxi service.. · Transportation assistance may improve research engagement for historically marginalized people..

Racial and Ethnic Inequities in Buprenorphine and Methadone Utilization Among Reproductive-Age Women with Opioid Use Disorder: an Analysis of Multi-state Medicaid Claims in the USA.

BACKGROUND: Associations between race/ethnicity and medications to treat OUD (MOUD), buprenorphine and methadone, in reproductive-age women have not been thoroughly studied in multi-state samples. OBJECTIVE: To evaluate racial/ethnic variation in buprenorphine and methadone receipt and retention in a multi-state U.S. sample of Medicaid-enrolled, reproductive-age women with opioid use disorder (OUD) at the beginning of OUD treatment. DESIGN: Retrospective cohort study. SUBJECTS: Reproductive-age (18-45 years) women with OUD, in the Merative™ MarketScan® Multi-State Medicaid Database (2011-2016). MAIN MEASURES: Differences by race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, "other" race/ethnicity) in the likelihood of receiving buprenorphine and methadone during the start of OUD treatment (yes/no) were estimated using multivariable logistic regression. Differences in time to medication discontinuation (days) by race/ethnicity were evaluated using multivariable Cox regression. RESULTS: Of 66,550 reproductive-age Medicaid enrollees with OUD (84.1% non-Hispanic White, 5.9% non-Hispanic Black, 1.0% Hispanic, 5.3% "other"), 15,313 (23.0%) received buprenorphine and 6290 (9.5%) methadone. Non-Hispanic Black enrollees were less likely to receive buprenorphine (adjusted odds ratio, aOR = 0.76 [0.68-0.84]) and more likely to be referred to methadone clinics (aOR = 1.78 [1.60-2.00]) compared to non-Hispanic White participants. Across both buprenorphine and methadone in unadjusted analyses, the median discontinuation time for non-Hispanic Black enrollees was 123 days compared to 132 days and 141 days for non-Hispanic White and Hispanic enrollees respectively (χ2 = 10.6; P = .01). In adjusted analyses, non-Hispanic Black enrollees experienced greater discontinuation for buprenorphine and methadone (adjusted hazard ratio, aHR = 1.16 [1.08-1.24] and aHR = 1.16 [1.07-1.30] respectively) compared to non-Hispanic White peers. We did not observe differences in buprenorphine or methadone receipt or retention for Hispanic enrollees compared to the non-Hispanic White enrollees. CONCLUSIONS: Our data illustrate inequities between non-Hispanic Black and non-Hispanic White Medicaid enrollees with regard to buprenorphine and methadone utilization in the USA, consistent with literature on the racialized origins of methadone and buprenorphine treatment.

Video Instruction for Pushing in the Second Stage: a randomized controlled trial.

BACKGROUND: The second stage of labor requires active patient engagement. Previous studies suggest that coaching can influence the second stage of labor duration. However, a standardized education tool has not been established, and patients face many barriers to accessing childbirth education before delivery. OBJECTIVE: This study aimed to investigate the effect of an intrapartum video pushing education tool on the second stage of labor duration. STUDY DESIGN: This was a randomized controlled trial of nulliparous patients with singleton pregnancies ≥37 weeks of gestation admitted for induction of labor or spontaneous labor with neuraxial anesthesia. Patients were consented on admission and block randomized in active labor to 1 of 2 arms in a 1:1 ratio. The study arm viewed a 4-minute video before the second stage of labor on what to anticipate in the second stage of labor and pushing techniques. The control arm received the standard of care: bedside coaching at 10 cm dilation from a nurse or physician. The primary outcome was second stage of labor duration. The secondary outcomes were birth satisfaction (using the Modified Mackey Childbirth Satisfaction Rating Scale), mode of delivery, postpartum hemorrhage, clinical chorioamnionitis, neonatal intensive care unit admission, and umbilical artery gases. Of note, 156 patients were needed to detect a 20% decrease in the second stage of labor duration with 80% power, 2-sided alpha level of .05, and 10% loss after randomization. Funding was provided by the Lucy Anarcha Betsy award from the division of clinical research at Washington University. RESULTS: Of 161 patients, 81 were randomized to standard of care, and 80 were randomized to intrapartum video education. Among these patients, 149 progressed to the second stage of labor and were included in the intention-to-treat analysis: 69 in the video group and 78 in the control group. Maternal demographics and labor characteristics were similar between groups. The second stage of labor duration was statistically similar between the video arm (61 minutes [interquartile range, 20-140]) and the control arm (49 minutes [interquartile range, 27-131]) (P=.77). There was no difference in mode of delivery, postpartum hemorrhage, clinical chorioamnionitis, neonatal intensive care unit admission, or umbilical artery gases between groups. Although the overall birth satisfaction score on the Modified Mackey Childbirth Satisfaction Rating Scale was similar between groups, patients in the video group rated their "level of comfort during birth" and "attitude of the doctors in birth" significantly higher or more positively than patients in the control group (P<.05 for both). CONCLUSION: Intrapartum video education was not associated with a shorter second stage of labor duration. However, patients who received video education reported a higher level of comfort and a more favorable perception of their physician, suggesting that video education may be a helpful tool to improve the birth experience.

Association between Elevated Intrauterine Resting Tone during Labor and Neonatal Morbidity.

OBJECTIVE: Internal contraction monitoring provides a quantitative assessment of intrauterine resting tone. During the course of labor, elevated intrauterine resting tone may be identified. We hypothesized that elevated intrauterine resting tone could lead to compression of the spiral arteries, thus limiting uterine blood flow and resulting in neonatal compromise. Therefore, our objective was to assess the association between elevated resting tone during labor and neonatal morbidity. STUDY DESIGN: This was a secondary analysis of a prospective cohort study of singleton deliveries at ≥37 weeks of gestation. Patients with ruptured membranes and an intrauterine pressure catheter in place for at least 30 minutes prior to delivery were included. Intrauterine resting tone was calculated as the average baseline pressure between contractions during the 30 minutes prior to delivery. The study group had elevated intrauterine resting tone, defined as intrauterine resting tone ≥75th percentile (≥12.3 mm Hg). Primary outcome was composite neonatal morbidity: hypoxic-ischemic encephalopathy, hypothermia treatment, intubation, seizures, umbilical arterial pH ≤7.1, oxygen requirement, or death. Secondary outcomes included umbilical artery pH <7.2, lactate ≥4 mmol/L, and rates of neonatal intensive care unit admission. RESULTS: Of the 8,580 patients in the cohort, 2,210 (25.8%) met the inclusion criteria. The median intrauterine resting tone was 9.7 mm Hg (interquartile range: 7.3-12.3 mm Hg). Elevated resting tone was associated with a shorter median duration of the first stage of labor (10.0 vs. 11.0 hours, p < 0.01) and lower rates of labor induction and oxytocin augmentation (p < 0.01). Neonatal composite morbidity was higher among patients with elevated intrauterine resting tone (5.1 vs. 2.9%, p = 0.01). After adjusting for chorioamnionitis and amnioinfusion, elevated intrauterine resting tone was associated with increased risk of neonatal morbidity (adjusted odds ratio: 1.70, 95% confidence interval: 1.06-2.74). CONCLUSION: Our findings suggest that elevated intrauterine resting tone is associated with increased risk of neonatal composite morbidity. KEY POINTS: · Higher intrauterine resting tone is associated with increased risk of neonatal morbidity.. · Elevated intrauterine tone can negatively impact umbilical artery pH and lactate levels.. · If elevated intrauterine pressure is noted, we recommend close monitoring of fetal status..

The Impact of Cervical Effacement at Time of Amniotomy in Patients Undergoing Induction of Labor.

OBJECTIVE: There is evidence to suggest that early amniotomy during induction of labor is advantageous. However, following cervical ripening balloon removal, the cervix remains less effaced and the utility of amniotomy in this setting is less clear. We investigated whether cervical effacement at the time of amniotomy impacts outcomes among nulliparas undergoing induction of labor. STUDY DESIGN: This was a secondary analysis of a prospective cohort of singleton, term, nulliparous patients at a tertiary care center undergoing induction of labor and amniotomy. The primary outcome was completion of the first stage of labor. Secondary outcomes were vaginal delivery and postpartum hemorrhage. Outcomes were compared between patients with cervical effacement ≤50% (low effacement) and >50% (high effacement) at time of amniotomy. Multivariable logistic regression was used calculate risk ratios (RR) to adjust for confounders including cervical dilation. Stratified analysis was performed in patients with cervical ripening balloon use. A post hoc sensitivity analysis was performed to further control for cervical dilation. RESULTS: Of 1,256 patients, 365 (29%) underwent amniotomy at low effacement. Amniotomy at low effacement was associated with reduced likelihood of completing the first stage (aRR: 0.87 [95% confidence interval, CI: 0.78-0.95]) and vaginal delivery (aRR: 0.87 [95% CI: 0.77-0.96]). Although amniotomy at low effacement was associated with lower likelihood of completing the first stage in all-comers, those who had amniotomy performed at low effacement following cervical ripening balloon expulsion were at the highest risk (aRR: 0.84 [95% CI: 0.69-0.98], p for interaction = 0.04) In the post hoc sensitivity analysis, including patients who underwent amniotomy at 3- or 4-cm dilation, low cervical effacement remained associated with a lower likelihood of completing the first stage of labor. CONCLUSION: Low cervical effacement at time of amniotomy, particularly following cervical ripening balloon expulsion, is associated with a lower likelihood of successful induction. KEY POINTS: · Low cervical effacement at amniotomy was associated with lower rates of complete dilation.. · Effacement at amniotomy is especially important for patients who had a cervical ripening balloon.. · Providers should consider cervical effacement when timing amniotomy for nulliparous term patients..

Severity of intrapartum fever and neonatal outcomes.

BACKGROUND: The few studies that have addressed the relationship between severity of intrapartum fever and neonatal and maternal morbidity have had mixed results. The impact of the duration between reaching maximum intrapartum temperature and delivery on neonatal outcomes remains unknown. OBJECTIVE: To test the association of severity of intrapartum fever and duration from reaching maximum temperature to delivery with neonatal and maternal morbidity. STUDY DESIGN: This was a secondary analysis of a prospective cohort of term, singleton patients admitted for induction of labor or spontaneous labor who had intrapartum fever (≥38°C). Patients were divided into 3 groups according to maximum temperature during labor: afebrile (<38°C), mild fever (38°C-39°C), and severe fever (>39°C). The primary outcome was composite neonatal morbidity (umbilical artery pH <7.1, mechanical ventilation, respiratory distress, meconium aspiration with pulmonary hypertension, hypoglycemia, neonatal intensive care unit admission, and Apgar <7 at 5 minutes). Secondary outcomes were composite neonatal neurologic morbidity (hypoxic-ischemic encephalopathy, hypothermia treatment, and seizures) and composite maternal morbidity (postpartum hemorrhage, endometritis, and maternal packed red blood cell transfusion). Outcomes were compared between the maximum temperature groups using multivariable logistic regression. Cox proportional-hazards regression modeling accounted for the duration between reaching maximum intrapartum temperature and delivery. RESULTS: Of the 8132 patients included, 278 (3.4%) had a mild fever and 74 (0.9%) had a severe fever. The incidence of composite neonatal morbidity increased with intrapartum fever severity (afebrile 5.4% vs mild 18.0% vs severe 29.7%; P<.01). After adjusting for confounders, there were increased odds of composite neonatal morbidity with severe fever compared with mild fever (adjusted odds ratio, 1.93 [95% confidence interval, 1.07-3.48]). Severe fevers remained associated with composite neonatal morbidity compared with mild fevers after accounting for the duration between reaching maximum intrapartum temperature and delivery (adjusted hazard ratio, 2.05 [95% confidence interval, 1.23-3.43]). Composite neonatal neurologic morbidity and composite maternal morbidity were not different between patients with mild and patients with severe fevers. CONCLUSION: Composite neonatal morbidity correlated with intrapartum fever severity in a potentially dose-dependent fashion. This correlation was independent of the duration from reaching maximum intrapartum temperature to delivery, suggesting that clinical management of intrapartum fever, in terms of timing or mode of delivery, should not be affected by this duration.

Changes in the Antenatal Utilization of High-Risk Obstetric Services and Stillbirth Rate during the COVID-19 Pandemic.

OBJECTIVE: The primary objective of this study was to evaluate coronavirus 2019 (COVID-19) pandemic-related changes in the antenatal utilization of high-risk obstetric services. Our secondary objective was to characterize change in stillbirth rate during the pandemic. STUDY DESIGN: This is a retrospective, observational study performed at a single, tertiary care center. Maternal-Fetal Medicine (MFM) visits, ultrasounds, and antenatal tests of fetal well-being during the pandemic epoch (2020), which spans the first 12 weeks of the year to include pandemic onset and implementation of mitigation efforts, were compared with the same epoch of the three preceding years visually and using general linear models to account for week and year effect. An analysis of stillbirth rate comparing the pandemic time period to prepandemic was also performed. RESULTS: While there were decreased MFM visits and antenatal tests of fetal well-being during the pandemic epoch compared with prepandemic epochs, only the decrease in MFM visits by year was statistically significant (p < 0.001). The stillbirth rate during the pandemic epoch was not significantly different when compared with the prepandemic period and accounting for both week (p = 0.286) and year (p = 0.643) effect. CONCLUSION: The COVID-19 pandemic resulted in a significant decrease in MFM visits, whereas obstetric ultrasounds and antenatal tests of fetal well-being remained unchanged. While we observed no change in the stillbirth rate compared with the prepandemic epoch, our study design and sample size preclude us from making assumptions of association. Our findings may support future work investigating how changes in prenatal care for high-risk obstetric patients influence perinatal outcomes. KEY POINTS: · MFM visits significantly decreased during the COVID-19 pandemic epoch.. · The overall stillbirth rate during the COVID-19 pandemic epoch was not significantly changed.. · Larger studies are needed to capitalize on these changes to evaluate rare outcomes such as stillbirth..

The Impact of a Multidisciplinary Opioid Use Disorder Prenatal Clinic on Breastfeeding Rates and Postpartum Care.

OBJECTIVE: To evaluate the hypothesis that patients with opioid use disorder (OUD), who receive prenatal care in a multidisciplinary, prenatal OUD clinic, have comparable postpartum breastfeeding rates, prenatal and postpartum visit compliance, and postpartum contraceptive use when compared with matched controls without a diagnosis of OUD. STUDY DESIGN: This was a retrospective, matched, cohort study that included all patients who received prenatal care in a multidisciplinary, prenatal OUD clinic-Clinic for Acceptance Recovery and Empowerment (CARE)-between September 2018 and August 2020. These patients were maintained on opioid agonist therapy (OAT) throughout their pregnancy. CARE patients were matched to controls without OUD in a 1:4 ratio for mode of delivery, race, gestational age ± 1 week, and delivery date ± 6 months. The primary outcome was rate of exclusive breastfeeding at maternal discharge. Secondary outcomes included adherence with prenatal care (≥4 prenatal visits), adherence with postpartum care (≥1 postpartum visit), postpartum contraception plan prior to delivery, and type of postpartum contraceptive use. Conditional multivariate logistic regression was used to account for possible confounders in adjusted calculations. RESULTS: A total of 210 patients were included (42 CARE and 168 matched controls). Despite having lower rates of adequate prenatal care, 40 CARE patients (95%) were exclusively breastfeeding at discharge resulting in CARE patients being significantly more likely to be breastfeeding at discharge (adjusted relative risk (aRR): 1.28, 95% confidence interval [CI]: 1.05-1.55). CARE patients and controls demonstrated no difference in postpartum visit compliance (86 vs. 81%, aRR: 1.03, 95% CI: 0.76-1.40) or effective, long-term contraception use (48 vs. 48%; aRR: 0.81, 95% CI: 0.36-1.84). CONCLUSION: In the setting of multidisciplinary OUD prenatal care during pregnancy, patients with OUD were more likely to be breastfeeding at the time of discharge than matched controls, with no difference in postpartum visit compliance or effective, long-term contraception. KEY POINTS: · Women with OUD are more likely to breastfeed when engaged in a multidisciplinary prenatal clinic.. · Women with OUD had no difference in LARC use when engaged in a multidisciplinary prenatal clinic.. · Women with OUD had no difference in postpartum visit rate in a multidisciplinary prenatal clinic..

The impact of physical activity during pregnancy on labor and delivery.

BACKGROUND: Physical activity in pregnancy is associated with decreased risks of adverse pregnancy outcomes such as gestational diabetes and preeclampsia. However, the relationship between the amount and type of physical activity during pregnancy and subsequent labor outcomes remains unclear. OBJECTIVE: This study aimed to test the hypothesis that higher levels of physical activity across different lifestyle domains in pregnancy are associated with a shorter duration of labor. STUDY DESIGN: This study is a secondary analysis of a prospective cohort study in which patients with singleton pregnancies without a major fetal anomaly were administered the Kaiser Physical Activity Survey in each trimester. The Kaiser Physical Activity Survey was designed specifically to quantify various types of physical activities in women and includes 4 summative indices-housework/caregiving, active living habits, sports, and occupation. The study included women at full-term gestations admitted for induction of labor or spontaneous labor. The primary outcome of this analysis was duration of the second stage of labor. Secondary outcomes were duration of the active stage, prolonged first and second stage, mode of delivery, rates of second-stage cesarean delivery, operative vaginal delivery, severe perineal lacerations, and postpartum hemorrhage. These outcomes were compared between patients with and without high physical activity levels, defined as overall Kaiser Physical Activity Survey score ≥75th percentile in the third trimester. Multivariable logistic regression was used to adjust for obesity and epidural use. In addition, a subgroup analysis of nulliparous patients was performed. RESULTS: A total of 811 patients with complete Kaiser Physical Activity Survey data in the third trimester were included in this analysis. The median Kaiser Physical Activity Survey score was 9.5 (8.2-10.8). Of the 811 patients, 203 (25%) had higher levels of physical activity in pregnancy. There was no difference in the duration of the second stage of labor between patients with and without higher physical activity levels (1.29±2.94 vs 0.97±2.08 hours; P=.15). The duration of active labor was significantly shorter in patients with higher levels of physical activity (5.77±4.97 vs 7.43±6.29 hours; P=.01). Patients with higher physical activity levels were significantly less likely to have a prolonged first stage (9.8% vs 19.4%; P<.01; adjusted relative risk, 0.55; 95% confidence interval, 0.34-0.83). However, rates of prolonged second-stage cesarean delivery, operative vaginal deliveries, and perineal lacerations were similar between the 2 groups. CONCLUSION: Patients who are more physically active during pregnancy have a shorter duration of active labor.

Hepatitis C and obstetrical morbidity in a substance use disorder clinic: a role for telemedicine?

BACKGROUND: Hepatitis C infection often co-occurs with substance use disorders in pregnancy. Accessing hepatitis C treatment is challenging because of loss to follow-up in the postpartum period, attributable to social and financial barriers to care. Telemedicine has been explored as a means of increasing routine postpartum care, but the potential impact on retention in and completion of care for postpartum hepatitis C has not been assessed. OBJECTIVE: This study aimed to evaluate the impact of hepatitis C on obstetrical morbidity in a substance use disorder-specific prenatal clinic, and the effect of Infectious Disease telemedicine consultation on subsequent treatment delivery. STUDY DESIGN: We performed a retrospective cohort study of all patients in our substance use disorder prenatal clinic from June 2018 to February 2023. Telemedicine consults for hepatitis C diagnoses began in March 2020 and included electronic chart review by Infectious Disease when patients were unable to be seen. Our primary outcome was composite obstetrical morbidity (preterm birth, preeclampsia, fetal growth restriction, fetal anomaly, abruption, postpartum hemorrhage, or chorioamnionitis) compared between patients with and without active hepatitis C. We additionally evaluated rates of completed referral and initiation of hepatitis C treatment before and after implementation of telemedicine consult. RESULTS: A total of 224 patients were included. Of the 222 patients who underwent screening, 71 (32%) were positive for active hepatitis C. Compared with patients without hepatitis C, a higher proportion of patients with hepatitis C were White (80% vs 58%; P=.02), had a history of amphetamine use (61% vs 32%; P<.01), injection drug use (72% vs 38%; P<.01), or overdose (56% vs 29%; P<.01), and were on methadone (37% vs 18%; P<.01). There was no difference in the primary outcome of composite obstetrical morbidity. The rate of hepatitis C diagnosis was not statistically significantly different between the pre- and posttelemedicine cohorts (N=29 [41%], N=42 [27%]), and demographics of hepatitis C virus-positive patients were similar, with most being unemployed, single, and publicly insured. A lower proportion of patients in the posttelemedicine group reported heroin use compared with the pretelemedicine cohort (62% vs 90%; P=.013). After implementation of telemedicine, patients were more likely to attend the visit (19% vs 44%; P=.03), and positive patients were much more likely to receive treatment (14% vs 57%; P<.01); 100% of visits in the posttelemedicine group occurred via telemedicine. There were 7 patients who were prescribed treatment by their obstetrician after chart review by Infectious Disease. CONCLUSION: Patients with and without hepatitis C had similar maternal and neonatal outcomes, with multiple indicators of social and financial vulnerability. Telemedicine Infectious Disease consult was associated with increased follow-up and hepatitis C treatment, and obstetricians were able to directly prescribe. Because patients with substance use disorders and hepatitis C may have increased barriers to care, telemedicine may represent an opportunity for intervention.

County-level neonatal opioid withdrawal syndrome rates and real-world access to buprenorphine during pregnancy: An audit ("secret shopper") study in Missouri.

Background: Amid rising rates of neonatal opioid withdrawal syndrome (NOWS) worldwide and in many regions of the USA, we conducted an audit study ("secret shopper study") to evaluate the influence of county-level buprenorphine capacity and rurality on county-level NOWS rates. Methods: In 2019, up to three phone calls were made to buprenorphine prescribers in the state of Missouri (USA). County-level buprenorphine capacity was defined as the number of clinicians (across all specialties) accepting pregnant people divided by the number of births. Multivariable negative binomial regression models estimated associations between buprenorphine capacity, rurality, and county-level NOWS rates, controlling for potential confounders (i.e., poverty, unemployment, and physician shortages) that may correspond to higher rates of NOWS and lower rates of buprenorphine prescribing. Analyses were stratified using tertiles of county-level overdose rates (top, middle, and lowest 1/3 of overdose rates). Results: Of 115 Missouri counties, 81(70 %) had no buprenorphine capacity, 17(15 %) were low-capacity (<0.5-clinicians/1,000 births), and 17(15 %) were high-capacity (≥0.5/1,000 births). The mean NOWS rate was 6.5/1,000 births. In Missouri counties with both the highest and lowest opioid overdose rates, higher buprenorphine capacity did not correspond to decreases in NOWS rates (incidence rate ratio[IRR]=1.23[95 %-confidence-interval[CI]=0.65-2.32] and IRR=1.57[1.21-2.03] respectively). Rurality did not correspond to greater NOWS burden in both Missouri counties with highest and lowest opioid overdose rates. Conclusions: The vast majority of counties in Missouri have no capacity for buprenorphine prescribing during pregnancy. Rurality and lower buprenorphine capacity did not significantly predict elevated rates of NOWS.

Individual-Level and Community-Level Predictors of Healthy Pregnancy Outcomes in Multigravid Black Women.

OBJECTIVE: To identify individual- and community-level factors that predict the odds of multigravid Black women having consecutive pregnancies without adverse pregnancy outcomes. METHODS: We conducted a secondary analysis of 515 multigravid Black women from a longitudinal observational study (2017-2019). We assessed the presence of adverse pregnancy outcomes (hypertensive disorders, gestational diabetes, preterm birth, fetal growth restriction, placental abruption, and pregnancy loss) for the index and prior pregnancies. We examined U.S. Census data, medical records, and surveys across multiple socioecologic domains: personal, behavioral, socioeconomic, and policy. We estimated adjusted odds ratios (aORs) and 95% CIs for the association between individual- and community-level factors and consecutive healthy pregnancies using hierarchical logistic regression models adjusted for maternal age, body mass index (BMI), gravidity, interpregnancy interval, and median household income. RESULTS: Among 515 multigravid Black women (age 27±5 years, BMI 31.4±8.9, gravidity 4±2), 38.4% had consecutive healthy pregnancies without adverse pregnancy outcomes. Individual-level factors associated with consecutive healthy pregnancies included normal glucose tolerance (aOR 3.9, 95% CI, 1.2-12.1); employment (aOR 1.9, 95% CI, 1.2-2.9); living in communities with favorable health indicators for diabetes, hypertension, and physical activity; and household income of $50,000 per year or more (aOR 3.5, 95% CI, 1.4-8.7). When individual and community factors were modeled together, only income and employment at the individual and community levels remained significant. CONCLUSION: Individual and community income and employment are associated with consecutive healthy pregnancies in a cohort of Black patients, emphasizing the need for comprehensive, multilevel systems interventions to reduce adverse pregnancy outcomes for Black women.

Dietary risk factors for hypertensive disorders of pregnancy.

OBJECTIVE: To assess whether diet quality and specific dietary components are associated with hypertensive disorders of pregnancy (HDP). STUDY DESIGN: Nested case control study in a prospectively collected cohort of 450 participants with singleton pregnancies who completed the National Institutes of Health Diet Health Questionnaire II (DHQ-II) in the third trimester or within 3 months of delivery. Patients with fetal anomalies, conception by in-vitro fertilization, and deliveries at outside hospitals were excluded from the original prospective cohort study. Cases were patients diagnosed with HDP and controls were patients without HDP. Cases and controls were matched by BMI class in a 1:2 ratio. Exposures of interest were HEI-2015 score components and other DHQ-II dietary components including minerals, caffeine, and water. These dietary components were compared between cohorts using univariate analyses. MAIN OUTCOME MEASURES: HEI-2015 total scores representing diet quality, component scores, and objective background data between patients with HDP and patients without HDP. RESULTS: 150 patients with HDP were matched to 300 controls without HDP. Baseline demographics were similar between groups, including BMI. Patients with HDP were less likely to have high quality diets (HEI ≥ 70) than controls (7.3 % v 15.7 %, P = 0.02). HDP were associated with significantly higher dairy, saturated fat, and sodium intake compared to controls. Other components were similar between groups. CONCLUSION: Patients with HDP are more likely to have lower diet quality and higher consumption of sodium, dairy, and saturated fats. These results can be used to study antenatal diet modification in patients at high risk of HDP.

Treatment of metastatic rectal squamous cell carcinoma in a pregnant patient.
