    Betamethasone as a potential treatment for preterm birth associated with sterile intra-amniotic inflammation: a murine study
    (2021) Galaz, Jose; Romero, Roberto; Arenas-Hernandez, Marcia; Panaitescu, Bogdan; Para, Robert; Gomez-Lopez, Nardhy
    Objectives: Preterm birth remains the leading cause of perinatal morbidity and mortality worldwide. Preterm birth is preceded by spontaneous preterm labor, which is commonly associated with sterile intra-amniotic inflammation; yet, no approved treatment exists for this clinical condition. Corticosteroids are the standard of care to improve neonatal outcomes in women at risk of preterm birth. Herein, we first validated our model of alarmininduced preterm birth. Next, we investigated whether treatment with betamethasone could prevent preterm birth resulting from sterile intra-amniotic inflammation in mice.

    Cellular immune responses in amniotic fluid of women with a sonographic short cervix
    (2020) Galaz, Jose; Romero, Roberto; Xu, Yi; Miller, Derek; Levenson, Dustyn; Para, Robert; Varrey, Aneesha; Hsu, Richard; Tong, Anna; Hassan, Sonia S.; Hsu, Chaur-Dong; Gomez-Lopez, Nardhy
    Objectives: A sonographic short cervix is one of the strongest predictors of preterm delivery. However, the cellular immune composition of amniotic fluid in women with a short cervix has not yet been described. Herein, we determined cellular and soluble immune responses in amniotic fluid from pregnant women with a mid-trimester asymptomatic short cervix.

    Cellular immune responses in amniotic fluid of women with preterm prelabor rupture of membranes
    (WALTER DE GRUYTER GMBH, 2020) Galaz, Jose; Romero, Roberto; Slutsky, Rebecca; Xu, Yi; Motomura, Kenichiro; Para, Robert; Pacora, Percy; Panaitescu, Bogdan; Hsu, Chaur Dong; Kacerovsky, Marian; Gomez Lopez, Nardhy
    Background: Preterm birth is the leading cause of perinatal morbidity and mortality. Preterm prelabor rupture of membranes (pPROM) occurs in 30% of preterm births; thus, this complication is a major contributor to maternal and neonatal morbidity. However, the cellular immune responses in amniotic fluid of women with pPROM have not been investigated.

    Microbial burden and inflammasome activation in amniotic fluid of patients with preterm prelabor rupture of membranes
    (2020) Theis, Kevin R.; Romero, Roberto; Motomura, Kenichiro; Galaz, Jose; Winters, Andrew D.; Pacora, Percy; Miller, Derek; Slutsky, Rebecca; Florova, Violetta; Levenson, Dustyn; Para, Robert; Varrey, Aneesha; Kacerovsky, Marian; Hsu, Chaur-Dong; Gomez-Lopez, Nardhy
    Background: Intra-amniotic inflammation, which is associated with adverse pregnancy outcomes, can occur in the presence or absence of detectable microorganisms, and involves activation of the inflammasome. lntra-amniotic inflammasome activation has been reported in clinical chorioamnionitis at term and preterm labor with intact membranes, but it has not yet been investigated in women with preterm prelabor rupture of membranes (preterm PROM) in the presence/absence of detectable microorganisms. The aim of this study was to determine whether, among women with preterm PROM, there is an association between detectable microorganisms in amniotic fluid and intra-amniotic inflammation, and whether intra-amniotic inflammasome activation correlates with microbial burden.
