The interaction between vaginal microbiota, cervical length, and vaginal progesterone treatment for preterm birth risk
BACKGROUND Preterm birth is the primary cause of infant death worldwide. A short cervix in the second trimester of pregnancy is a risk factor for preterm birth. In specific patient cohorts, vaginal progesterone reduces this risk. Using 16S rRNA gene sequencing, we undertook a prospective study in women at risk of preterm birth (n = 161) to assess (1) the relationship between vaginal microbiota ...
متن کاملManagement of Abnormal Vaginal Flora as a Risk Factor for Preterm Birth
Prevention of preterm birth remains a major challenge in obstetrics. While over the years a lot of attention has been given to the structural deficiencies, like uterine abnormalities, or ‘weak’ or ‘insufficient’ cervix, during the last decades the importance of ascending infection as a possible cause of preterm birth, preterm rupture of the membranes and intrauterine infection has become increa...
متن کاملThe frequent shift to intermediate flora in preterm delivery cases after abnormal vaginal flora screening
The effect of screening and treatment for abnormal vaginal flora on the reduction of preterm deliveries remains controversial. We evaluated whether this screening and treatment reduces the preterm delivery rate for general-population pregnant women. Pregnant women of the Intervention group (n = 574) underwent the screening test and the treatment of vaginal metronidazole during the early second ...
متن کاملCervical length versus vaginal PH in the second trimester as preterm birth predictor
OBJECTIVE To evaluate diagnostic value of vaginal pH and cervical length measurement in the second trimester of pregnancy as a preterm labor (PTL) predictor. METHODS During a prospective cohort study 438 uncomplicated singleton pregnant women between 18 and 24 weeks of gestation were assessed regarding vaginal PH and cervical length. Vaginal pH was measured using Ph-indicator strips and cervi...
متن کاملVaginal bleeding during pregnancy and preterm birth.
This study investigated the relation between self-reported vaginal bleeding during pregnancy and preterm birth in a prospective cohort of 2,829 pregnant women enrolled from prenatal clinics between 1995 and 2000 in central North Carolina. The overall association between vaginal bleeding and preterm birth was modest (risk ratio (RR) = 1.3, 95% confidence interval (CI): 1.1, 1.6). Bleeding in the...
