Abstract:OBJECTIVE: Preterm birth (PTB) is a leading cause of neonatal morbidity and mortality. Yet, transvaginal ultrasound (TVUS) cervical length (CL) screening suboptimally predicts spontaneous PTB (SPTB). Abnormal remodeling of glandular crypts along the cervical canal may contribute to increased PTB risk via premature cervical ripening, which may correspond to no visualizable cervical gland area (CGA) on TVUS (Figure 1). This study aims to determine if no visualizable ("absent") CGA at CL screening is predictive o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
