Co-occurrence of mental illness and substance use among US pregnant individuals, 2012-2021.

AIM: Substance use disorders are increasingly prevalent among pregnant individuals, with evident risks of adverse perinatal outcomes. This study examines substance use (tobacco, alcohol and marijuana) among pregnant individuals with mental illness. METHODS: A national representative sample of pregnant individuals were derived from 2012 to 2021 National Survey of Drug Use and Health data. Associations of past-year mental illness with past-month polysubstance use and each substance use were analyzed by logistic regression models, with complex sampling weights and survey year. RESULTS: Among 6801 pregnant individuals, 16.4% reported having any mental illness (AMI) in 2012 and 2013, increasing to 23.8% in 2020-2021; and SMI increased from 3.3% to 9.4%. Polysubstance use increased disproportionately among those with severe mental illness (SMI), from 14.0% to 18.6%. Pregnant individuals with greater severity of mental illness had higher odds of polysubstance use (Adjusted Odds Ratio, 95% CI: AMI but no SMI vs. without AMI: 1.59 [1.04, 2.44]; SMI vs. without AMI: 5.48 [2.77, 10.82]). CONCLUSIONS: Pregnant individuals with greater severity of mental illness were more likely to engage in substance use. Evidence-based educational, screening and treatment services, and public policy changes are warranted to mitigate the harmful health outcomes of substance use among US pregnant individuals with mental illness.

The role of race/ethnicity in cerclage efficacy.

OBJECTIVE: To measure the impact of race/ethnicity on cerclage efficacy, as measured by the prevalence of spontaneous preterm birth (PTB), in a cohort of patients with history-indicated, ultrasound-indicated and physical-exam indicated cerclages. METHODS: We conducted a retrospective cohort study of patients undergoing history-indicated, ultrasound-indicated and physical-exam indicated cerclage placement from January 2003 to July 2013 at a tertiary care hospital. Patients' race/ethnicity was self-declared. Our primary outcome was spontaneous preterm birth (SPTB) < 37 weeks. Subgroup analyses were performed for each of the three indications for cerclage. RESULTS: One hundred and eighty-one subjects met inclusion criteria. Forty-seven percent self-identified as non-Hispanic black (NHB), 12% as Hispanic and 41% as non-Hispanic white (NHW). There was no significant difference in the prevalence of SPTB < 37 weeks between the three race/ethnicity groups (33% versus 19% versus 40%, respectively, p = 0.22), nor for SPTB less than 34 or 28 weeks. Finally, there was no difference in SPTB prevalence by race after controlling for smoking, history of CKC/LEEP, and 17-OHPC with logistic regression. CONCLUSION: Race/ethnicity does not appear to be associated with cerclage efficacy, as measured by the risk of SPTB, in a cohort of patients with history-indicated, ultrasound-indicated and physical-exam indicated cerclages.

Intake of Caffeinated Soft Drinks before and during Pregnancy, but Not Total Caffeine Intake, Is Associated with Increased Cerebral Palsy Risk in the Norwegian Mother and Child Cohort Study.

BACKGROUND: Postnatal administration of caffeine may reduce the risk of cerebral palsy (CP) in vulnerable low-birth-weight neonates. The effect of antenatal caffeine exposure remains unknown. OBJECTIVE: We investigated the association of intake of caffeine by pregnant women and risk of CP in their children. METHODS: The study was based on The Norwegian Mother and Child Cohort Study, comprising >100,000 live-born children, of whom 222 were subsequently diagnosed with CP. Mothers reported their caffeine consumption in questionnaires completed around pregnancy week 17 (102,986 mother-child pairs), week 22 (87,987 mother-child pairs), and week 30 (94,372 mother-child pairs). At week 17, participants were asked about present and prepregnancy consumption. We used Cox regression models to estimate associations between exposure [daily servings (1 serving = 125 mL) of caffeinated coffee, tea, and soft drinks and total caffeine consumption] and CP in children, with nonconsumers as the reference group. Models included adjustment for maternal age and education, medically assisted reproduction, and smoking, and for each source of caffeine, adjustments were made for the other sources. RESULTS: Total daily caffeine intake before and during pregnancy was not associated with CP risk. High consumption (≥6 servings/d) of caffeinated soft drinks before pregnancy was associated with an increased CP risk (HR: 1.9; 95% CI: 1.2, 3.1), and children of women consuming 3-5 daily servings of caffeinated soft drinks during pregnancy weeks 13-30 also had an increased CP risk (HR: 1.7; 95% CI: 1.1, 2.8). A mean daily consumption of 51-100 mg caffeine from soft drinks during the first half of pregnancy was associated with a 1.9-fold increased risk of CP in children (HR: 1.9; 95% CI: 1.1, 3.6). CONCLUSIONS: Maternal total daily caffeine consumption before and during pregnancy was not associated with CP risk in children. The observed increased risk with caffeinated soft drinks warrants further investigation.

Training needs in operative obstetrics for maternal-fetal medicine fellows.

OBJECTIVE: To define residual operative obstetric training needs for first-year maternal-fetal medicine (MFM) fellows. METHODS: We administered a web-based survey to all 100 first-year fellows. We used descriptive statistics to report frequency data for 13 procedures, and logistic regression to estimate odds ratios for comfort in doing and teaching selected procedures. RESULTS: Response rate was 86% (n = 86). Fellows who completed residency in the Northeast/Midatlantic (n = 26) were less likely to report comfort doing or teaching low forceps deliveries (OR 0.21, 95% CI 0.05, 0.78; and 0.20, 95% CI 0.04, 0.85, respectively), while those completing fellowship in the West (n = 13), reported more comfort performing breech extraction of a second twin (OR 6.84, 95% CI 1.24, 51.50); fellows completing residency in the Southeast formed the referent group. Fellows reporting completion of the three selected procedures >5 times each during residency were significantly more likely to report comfort doing and teaching them as fellows. Type of residency program (community/academic) was not significantly associated with reported comfort. CONCLUSION: The wide range of operative obstetric experience fellows reported gaining in residency varies by region. Additional research is needed to understand competency and teaching ability for procedural skills, and many MFM fellows may need additional procedural experience.

Robotic resection of adnexal masses during pregnancy.

OBJECTIVE: To characterize the safety and feasibility of robotic adnexal surgery during pregnancy, and to compare surgical and obstetric outcomes for robotic versus laparoscopic treatment of adnexal masses during pregnancy. STUDY DESIGN: A retrospective cohort study of all cases of robotic resection of adnexal masses in gravid patients performed at our institution between 2006 and 2009 compared with 50 consecutive historic laparoscopic controls performed between 1999 and 2007. RESULTS: During the study period, 19 parturients underwent planned robotic resection of adnexal masses, all of which were uncomplicated. Compared with 50 consecutive laparoscopic controls, no differences in operative time, conversion to laparotomy, intraoperative or postoperative complications, or observed obstetric outcomes were apparent. The robotic cohort had a significantly shorter length of hospital stay (p < 0.01) and estimated blood loss (p = 0.02). CONCLUSION: Robotic resection of adnexal masses during pregnancy appears both safe and feasible, with similar surgical outcomes when compared with a historic laparoscopic cohort.

Efficient use of early obstetric sonography in the emergency department setting.

OBJECTIVES: Transvaginal sonography is frequently used in the emergency department (ED) to triage pregnancies of unknown location. The purpose of this study was to examine the utility of sonography in clinically stable patients with ß-human chorionic gonadotropin (ß-hCG) values below the discriminatory zone. METHODS: We conducted a retrospective cohort study of 408 consecutive ED patients who presented with pregnancies of unknown location and serum ß-hCG levels between 5 and 2500 mIU/mL and underwent transvaginal sonography. Women were classified as receiving immediate treatment or expectant management. Predictors associated with immediate treatment were assessed by bivariate analyses and logistic regression. RESULTS: Of the cohort, 361 women (88.5%) received expectant management, and 6.9%, 3.1%, and 0% of patients with pregnancies of unknown location and ß-hCG levels below 1000, 200, and 75 mIU/mL, respectively, received immediate treatment. Compared to the expectant management group, women receiving immediate treatment (n=47) were further from the last menstrual period (7.86 versus 6.10 weeks; P <.01), were more likely to report pain (59.6% versus 40.2% P = .01), had higher ß-hCG levels(1183 versus 608 mIU/mL; P <.01), and had lower hematocrit levels (35.7% versus 37.0%; P < .01), with pain the most predictive factor for immediate treatment (odds ratio,5.97; 95% confidence interval, 2.45-14.53). A model combining symptoms, ß-hCG, hematocrit, and weeks since the last menstrual period predicted the likelihood of sonography changing management from expectant management to immediate treatment with specificity of 98%. CONCLUSIONS: The diagnostic utility of sonography in clinically stable patients presenting to the ED in very early pregnancy is limited. A model using symptoms, ß-hCG, hematocrit, and the last menstrual period may aid clinicians to triage those who would benefit from immediate sonography.
