    Clinical chorioamnionitis at term X: microbiology, clinical signs, placental pathology, and neonatal bacteremia implications for clinical care
    (2021) Romero, Roberto; Pacora, Percy; Kusanovic, Juan Pedro; Jung, Eunjung; Panaitescu, Bogdan; Maymon, Eli; Erez, Offer; Berman, Susan; Bryant, David R.; Gomez-Lopez, Nardhy; Theis, Kevin R.; Bhatti, Gaurav; Kim, Chong Jai; Yoon, Bo Hyun; Hassan, Sonia S.; Hsu, Chaur-Dong; Yeo, Lami; Diaz-Primera, Ramiro; Marin-Concha, Julio; Lannaman, Kia; Alhousseini, Ali; Gomez-Roberts, Hunter; Varrey, Aneesha; Garcia-Sanchez, Angel; Gervasi, Maria Teresa
    Objectives: Clinical chorioamnionitis at term is considered the most common infection-related diagnosis in labor and delivery units worldwide. The syndrome affects 5-12% of all term pregnancies and is a leading cause of maternal morbidity and mortality as well as neonatal death and sepsis. The objectives of this study were to determine the (1) amniotic fluid microbiology using cultivation and molecular microbiologic techniques; (2) diagnostic accuracy of the clinical criteria used to identify patients with intraamniotic infection; (3) relationship between acute inflammatory lesions of the placenta (maternal and fetal inflammatory responses) and amniotic fluid microbiology and inflammatory markers; and (4) frequency of neonatal bacteremia.

    Microbial invasion of the amniotic cavity in pregnancies with small-for-gestational-age fetuses
    (WALTER DE GRUYTER GMBH, 2010) DiGiulio, Daniel B.; Gervasi, Maria Teresa; Romero, Roberto; Vaisbuch, Edi; Mazaki Tovi, Shali; Kusanovic, Juan Pedro; Seok, Kimberley S.; Gomez, Ricardo; Mittal, Pooja; Gotsch, Francesca; Chaiworapongsa, Tinnakorn; Oyarzun, Enrique; Kim, Chong Jai; Relman, David A.
    Objective: Microbial invasion of the amniotic cavity (MIAC) has been detected in women with preterm labor, preterm prelabor rupture of membranes (PROM), and in patients at term with PROM or in spontaneous labor. Intrauterine infection is recognized as a potential cause of fetal growth restriction; yet, the frequency of MIAC in pregnancies with small-for-gestational-age (SGA) fetuses is unknown. The aim of this study was to determine the frequency, diversity and relative abundance of microbes in amniotic fluid (AF) of women with an SGA neonate using a combination of culture and molecular methods.

    Should Bilateral Uterine Artery Notching Be Used in the Risk Assessment for Preeclampsia, Small-for-Gestational-Age, and Gestational Hypertension?
    (WILEY, 2010) Espinoza, Jimmy; Kusanovic, Juan Pedro; Bahado Singh, Ray; Gervasi, Maria Teresa; Romero, Roberto; Lee, Wesley; Vaisbuch, Edi; Mazaki Tovi, Shali; Mittal, Pooja; Gotsch, Francesca; Erez, Offer; Gomez, Ricardo; Yeo, Lami; Hassan, Sonia S.
    Objective. The purpose of this study was to determine the value of bilateral uterine artery notching in the second trimester in the risk assessment for preeclampsia, gestational hypertension, and small-for-gestational-age (SGA) without preeclampsia. Methods. This prospective cohort study included 4190 singleton pregnancies that underwent ultrasound examination between 23 and 25 weeks' gestation. The 95th percentiles of the mean pulsatility index (PI) and resistive index (RI) of both uterine arteries were calculated. Multivariable logistic regression analyses were performed to determine if bilateral uterine artery notching is an independent explanatory variable for the occurrence of preeclampsia, early-onset preeclampsia (<= 34 weeks), late-onset preeclampsia (>34 weeks), gestational hypertension, and delivery of an SGA neonate without preeclampsia, while controlling for confounding factors. Results. (1) The prevalence of preeclampsia, early-onset preeclampsia, late-onset preeclampsia, SGA, and gestational hypertension were 3.4%, 0.5%, 2.9%, 10%, and 7.9%, respectively; (2) 7.2% of the study population had bilateral uterine artery notching; and (3) bilateral uterine artery notching was an independent explanatory variable for the development of preeclampsia (odds ratio [OR] 2.1; 95% confidence interval [CI], 1.28-3.36), early-onset preeclampsia (OR, 4.47; 95% CI, 1.50-13.35), and gestational hypertension (OR, 1.50; 95% CI, 1.02-2.26), but not for late-onset preeclampsia or SGA. Conclusions. Bilateral uterine notching between 23 and 25 weeks' gestation is an independent risk factor for the development of early-onset preeclampsia and gestational hypertension. Thus, bilateral uterine artery notching should be considered in the assessment of risk for the development of these pregnancy complications.
