OBJECTIVE To measure the association between race-ethnicity and insurance status at preconception, delivery, and postpartum and the frequency of insurance gaps and transitions (disruptions) across these time points. METHODS We conducted a cross-sectional analysis of survey data from 107,921 women in 40 states participating in the Centers for Disease Control and Prevention's Pregnancy Risk Assessment and Monitoring System from 2015 to 2017. We calculated unadjusted estimates of insurance status at preconception, delivery, and postpartum and continuity across these time points for seven racial-ethnic categories (white non-Hispanic, black non-Hispanic, indigenous, Asian or Pacific Islander, Hispanic Spanish-speaking, Hispanic English-speaking, and mixed race or other). We also examined unadjusted estimates of uninsurance at each perinatal time period by state of residence. We calculated adjusted differences in the predicted probability of uninsurance at preconception, delivery, and postpartum using logistic regression models with interaction terms for race-ethnicity and income. RESULTS For each perinatal time point, all categories of racial-ethnic minority women experienced higher rates of uninsurance than white non-Hispanic women. From preconception to postpartum, 75.3% (95% CI 74.7-75.8) of white non-Hispanic women had continuous insurance compared with 55.4% of black non-Hispanic women (95% CI 54.2-56.6), 49.9% of indigenous women (95% CI 46.8-53.0) and 20.5% of Hispanic Spanish-speaking women (95% CI 18.9-22.2). In adjusted models, lower-income Hispanic women and indigenous women had a significantly higher predicted probability of uninsurance in the preconception and postpartum period compared with white non-Hispanic women. CONCLUSION Disruptions in perinatal insurance coverage disproportionately affect indigenous, Hispanic, and black non-Hispanic women. Differential insurance coverage may have important implications for racial-ethnic disparities in access to perinatal care and maternal-infant health.Hepatitis C virus (HCV) infection affects 170 million people worldwide, with at least 5% of individuals with HCV progressing to life-threatening complications, including hepatocellular carcinoma, within 20 years from acute infection. The World Health Organization has called for viral hepatitis elimination as a major public health threat by 2030. The recent development and availability of direct-acting antiviral drugs have been a game-changer in the HCV-treatment paradigm-response exceeds 90%, with minimal adverse events. Accordingly, the U.S. Preventive Services Task Force and the American Association for the Study of Liver Disease-Infectious Diseases Society of America 2019 guidelines recommend universal HCV screening for all adults aged 18-79 years, including pregnant women. Worldwide, up to 8% of pregnant women have HCV infection, with the prevalence being as high as 4% in the United States. Phorbol 12-myristate 13-acetate chemical structure Pregnancy is one of the few points of contact women of reproductive age have with their health care providers; therefore, pregnancy provides a crucial time for targeting this population for HCV screening. Children also benefit from maternal screening, because the primary route of infection in children is vertical transmission during pregnancy, and children are not routinely assessed for liver disease. In fact, 85-95% of children with HCV infection in the United States are not yet identified with current strategies. In this commentary, we highlight why universal screening in pregnant women should be recommended by the American College of Obstetricians and Gynecologists based on the current epidemiology of HCV and the upcoming U.S. Preventive Services Task Force-recommended screening changes for all adults aged 18-79 years. We also review the current screening paradigm and treatment options for pregnant women and their children.OBJECTIVE To evaluate the association between antenatal diagnosis of velamentous and marginal placental cord insertions with adverse perinatal outcomes of small-for-gestational-age (SGA) birth weight (less than the 5th percentile), caesarean birth, and perinatal mortality. METHODS Using a diagnostic imaging database, we performed a cohort study of all consecutive singleton pregnancies (35,391), including 1,427 cases of marginal and 107 cases of velamentous cord insertion, delivered after 24 6/7 weeks of gestation between January 1, 2012, and December 31, 2015, at a single Canadian tertiary care center. Cases with placenta previa, vasa previa, no documented cord insertion, or fetal anomalies were excluded. RESULTS In the overall cohort, the rate of birth weight less than the 5th percentile was 5.2%, the rate of cesarean delivery was 27.1%, and the rate of perinatal mortality was 0.24%. Velamentous cord insertion was associated with SGA (relative risk [RR] 2.19, 95% CI 1.28-3.74). This persisted after controlling for smoking during pregnancy, diabetes, and hypertension (adjusted odds ratio [aOR] 1.98, 95% CI 1.03-3.84). Velamentous cord insertion was also associated with an increased risk of caesarean birth (RR=1.38, 95% CI=1.08-1,77) and perinatal death (1.87%, RR 8.15, 95% CI 2.02-32.8), a relationship that persisted after controlling for smoking during pregnancy, diabetes, and hypertension (aOR 1.53, 95% CI 1.01-2.32). Marginal cord insertion was not associated with birth weight less than the 5th percentile (RR 1.23, 95% CI 1.00-1.51), cesarean delivery (RR 1.01, 95% CI 0.92-1.10), or perinatal death (RR 1.53, 95% CI 0.62-3.78). CONCLUSION Antenatal diagnosis of velamentous placental cord insertion is associated with birth weight less than the 5th percentile.Recommendations for screening for hepatitis B immunity in pregnancy and vaccinating susceptible women vary among professional societies. The American College of Obstetricians and Gynecologists recommends vaccinating high-risk women for hepatitis B. However, only one fourth of U.S. adults have received a complete hepatitis B vaccination series. Because two thirds of individuals with chronic hepatitis B are unaware of their diagnosis, risk-based screening for immunity followed by vaccination of susceptible women may not identify and protect all women at risk. Acquisition of hepatitis B poses short-term and long-term risks to maternal and fetal health, an outcome that can be prevented by vaccination. Hepatitis B vaccination in pregnancy is safe and efficacious and can be completed during the course of prenatal care. Universal screening for hepatitis B immunity and vaccination of susceptible women in pregnancy should be a priority during prenatal care. Cost-effectiveness studies are needed to validate this approach.
