Objective: To assess the frequency and associated characteristics of COVID-19 vaccine hesitancy among pregnant and postpartum individuals.
OBJECTIVE To examine the association between initial COVID‐19 vaccine hesitancy and subsequent vaccination among pregnant and postpartum individuals. DESIGN Prospective cohort SETTING A Midwestern tertiary care academic medical center. Individuals completed a baseline vaccine hesitancy assessment from 03/22/21 to 04/02/21, with subsequent ascertainment of vaccination status at 3 to 6 months follow‐up. METHODS We used multivariable Poisson regression to estimate the relative risk of vaccination by baseline vaccine hesitancy status, and then characteristics associated with vaccination. MAIN OUTCOMES Self‐report of COVID‐19 vaccination, and secondarily, consideration of COVID‐19 vaccination among those not vaccinated. RESULTS Of 456 individuals (93% pregnant, 7% postpartum) initially surveyed, 290 individuals (64%; 23% pregnant, 77% postpartum) provided subsequent vaccination status (median=17 weeks). Forty percent (116/290) reported COVID‐19 vaccine hesitancy at enrollment, of whom 52% reported subsequent vaccination at follow‐up. Few individuals transitioned during the study period from vaccine hesitant to vaccinated (10%); in comparison, 80% of those who were not vaccine hesitant were vaccinated at follow‐up (aRR: 0.19; 95% CI: 0.11, 0.33). Among those who remained unvaccinated at follow‐up, 38% who were vaccine hesitant at baseline were considering vaccination compared to 71% who were not vaccine hesitant (aRR: 0.48; 95% CI: 0.33, 0.67). Individuals who were older, parous, employed, and of higher educational attainment were more likely to be vaccinated, and those who identified as non‐Hispanic Black, were Medicaid beneficiaries, and still pregnant at follow‐up were less likely to be vaccinated. CONCLUSIONS COVID‐19 vaccine hesitancy persisted over time in the peripartum period, and few individuals who reported hesitancy at baseline were later vaccinated. Interventions that address vaccine hesitancy in pregnancy are needed. FUNDING Ms. Germann was supported by the New York Academy of Medicine David E. Rogers Fellowship Program.

Objective To define patterns of prescription and factors associated with choice of pharmacotherapy for gestational diabetes mellitus (GDM), namely metformin, glyburide and insulin, during a period of evolving professional guidelines.Desing Cross-sectional study.Setting US commercial insurance beneficiaries from Market-Scan (late 2015 to 2018).Study design We included women with GDM, singleton gestations, 15-51 years of age on pharmacotherapy. The exposure was pharmacy claims for metformin, glyburide and insulin.Main outcomes Pharmacotherapy for GDM with either oral agent, metformin or glyburide, compared with insulin as the reference, and secondarily, consequent treatment modification (addition and/or change) to metformin, glyburide or insulin.Results Among 37 762 women with GDM, we analysed data from 10 407 (28%) with pharmacotherapy, 21% with metformin (n = 2147), 48% with glyburide (n = 4984) and 31% with insulin (n = 3276). From late 2015 to 2018, metformin use increased from 17 to 29%, as did insulin use from 26 to 44%, whereas glyburide use decreased from 58 to 27%. By 2018, insulin was the most common pharmacotherapy for GDM; metformin was more likely to be prescribed by 9% compared with late 2015/16, but glyburide was less likely by 45%. Treatment modification occurred in 20% of women prescribed metformin compared with 2% with insulin and 8% with glyburide.Conclusions Insulin followed by metformin has replaced glyburide as the most common pharmacotherapy for GDM among a privately insured US population during a time of evolving professional guidelines. Further evaluation of the relative effectiveness and safety of metformin compared with insulin is needed.
ObjectiveTo assess the risk factors associated with heterosexual HIV transmission among South Indian discordant couples enrolled in clinical care. MethodsA nested matched case-control study of serodiscordant couples in which the HIV-infected partner (index case) was enrolled in care. Demographic and clinical characteristics, sexual behaviours, CD4 cell count and plasma HIV-1 RNA loads were measured at enrolment and longitudinally over 12 months of follow-up. The study included 70 cases who seroconverted during study follow-up and 167 matched controls who remained persistently serodiscordant. ResultsThe incidence of HIV infection among the initially seronegative partners was 6.52 per 100 personyears. Persistently discordant patients were more likely to have initiated highly active antiretroviral therapy (HAART) than patients in seroconverting relationships (62.9% vs. 42.9%) (P50.001). Patients in seroconverting relationships had significantly higher plasma viral loads (PVLs) than patients in discordant relationships at enrolment, at 6 months and at 12 months (Po0.05). Patients in seroconverting relationships were less likely to use condoms with their primary partners than patients in discordant relationships (Po0.05). Patients in relationships that seroconverted between 6 and 12 months were diagnosed more often with genital Herpes simplex than patients in discordant relationships (P50.001). In the univariate and multivariate logistic regression, the following variables were associated with seroconversion: PVL 4100 000 [odds ratio (OR): 1.82; 95% confidence interval (CI): 1.1-2.8], non-disclosure of HIV status (OR: 5.5; 95% CI: 4.3-6.2) and not using condoms (OR: 2.8; 95% CI: 2.4-3.6). ConclusionsCouples-based intervention models are crucial in preventing HIV transmission to seronegative spouses. Providing early treatment for sexually transmitted infections, HAART and enhancing condom use and disclosure could potentially decrease the risk of HIV transmission within Indian married couples. IntroductionAn increasing focus of HIV preventive strategies has been to move away from solely reducing the risk-taking behaviours of HIV-uninfected individuals to focusing on HIV-infected individuals who may continue to practice HIV risk-taking behaviours [1]. Studies from the developed and developing world have documented that a sizeable number of HIV-infected individuals continue to engage in unprotected sexual intercourse with HIV-serodiscordant partners [2][3][4][5][6]. Unprotected intercourse may be more common among HIV-infected individuals in steady or regular relationships than in casual or non-regular sexual *The first two authors contributed equally to this manuscript. [19]. The typical route of HIV transmission has been through unprotected heterosexual intercourse [20]; however, data about the incidence and risk factors associated with HIV transmission through heterosexual intercourse in India remains very limited [21]. The social construct of gender in India, which has evolved over many centuries, makes women highl...
BACKGROUND: Extremely preterm infants whose placenta had histologic evidence of chorioamnionitis have early brain dysfunction, but little is known about neurologic development at 10 years of age. OBJECTIVE: We investigated the association between histologic chorioamnionitis and neurodevelopmental impairment at 10 years among children born <28 weeks' gestation (extremely preterm). STUDY DESIGN: The multicenter Extremely Low Gestational Age Newborns study enrolled extremely preterm newborns from 2002 to 2004 at 14 hospitals in the United States. Chorioamnionitis was defined by histologic stage (early, moderate, and advanced) and grade (mild/moderate and severe) of chorionic plate and umbilical cord inflammation. The children were examined for cerebral palsy at 2 years and for autism spectrum disorder, cognitive impairment (intelligence quotient >2 standard deviations below the mean), and epilepsy at the age of 10 years by blinded evaluators using validated measures. Multivariable logistic regression with generalized estimating equations was used. RESULTS: Among 805 placentas, 43% (347/805) had histologic chorioamnionitis by moderate or advanced maternal stage, 36% (286/805) by severe maternal grade, 18% (132/737) by moderate or advanced fetal stage, and 1% (10/737) by severe fetal grade. The frequencies of impairments were 11% (88/767) for cerebral palsy, 7% (56/773) for autism spectrum disorder, 15% (120/788) for cognitive impairment, and 7% (52/ 763) for epilepsy. After adjustment for maternal age, body mass index, race, insurance status, maternal education, tobacco use, infant sex, and multiple gestations, the adjusted odds ratio for the association between histologic chorioamnionitis and cerebral palsy years was increased with advanced maternal stage (adjusted odds ratio, 2.5; 95% confidence interval, 1.6e3.9), severe maternal grade (adjusted odds ratio, 2.0; 95% confidence interval, 1.2e3.4), moderate fetal stage (adjusted odds ratio, 2.20; 95% confidence interval, 2.1e2.2), and mild or moderate fetal grade (adjusted odds ratio, 1.5; 95% confidence interval, 1.0e2.2). Similarly, the adjusted odds ratio for the association between histologic chorioamnionitis and epilepsy was increased with advanced maternal stage (adjusted odds ratio, 1.5; 95% confidence interval, 1.3e1.6) and severe fetal grade (adjusted odds ratio, 5.9; 95% confidence interval, 1.9e17.8). In addition, the adjusted odds ratio for the association between histologic chorioamnionitis and autism spectrum disorder was increased with mild or moderate fetal grade (adjusted odds ratio, 1.7; 95% confidence interval, 1.0e2.9). Histologic chorioamnionitis was not associated with cognitive impairment. These findings held after adjustment for gestational age at delivery. In contrast to histologic chorioamnionitis, a clinical diagnosis of chorioamnionitis was not associated with neurodevelopmental impairment. CONCLUSION: Histologic chorioamnionitis may be associated with some forms of neurodevelopmental impairment at 10 years of life among infants born <2...
We assess the relative contribution of viral and bacterial sexually transmitted infections (STIs) on HIV acquisition among southern African women in a nested case-control study within the Methods for Improving Reproductive Health in Africa (MIRA) trial. Cases were women with incident HIV infection; controls were HIV-uninfected at the time of case seroconversion selected in a 1 to 3 case to control ratio (risk-set sampling), matched on study site and time of follow-up. Conditional logistic regression models were used to calculate adjusted odds ratios (AORs) and population-attributable fractions (PAF). Among 4948 enrolled women, we analysed 309 cases and 927 controls. The overall HIV incidence rate was 4.0 per 100 women-years. The incidence of HIV infection was markedly higher in women who had prevalent Herpes simplex virus type 2 (HSV-2) (AOR: 2.14; 95% confidence interval [CI]: 1.55-2.96), incident HSV-2 (AOR: 4.43; 95% CI: 1.77-11.05) and incident Neisseria gonorrhoeae (AOR: 6.92; 95% CI: 3.01-15.90). The adjusted PAF of HIV incidence for prevalent HSV-2 was 29.0% (95% CI: 16.8-39.3), for incident HSV-2 2.1% (95% CI: 0.6-3.6) and for incident N. gonorrhoeae 4.1% (95% CI: 2.5-5.8). Women's greatest risk factors for HIV acquisition were incident bacterial and viral STIs. Women-centred interventions aimed at decreasing HIV incidence in young African women need to address these common co-morbid conditions.
