Ultrasound Measurement of Cervical Length as Predictor of Threatened Preterm Birth: a Predictive Model
TLDR
The findings of this study suggest association between sonographic measurement of cervical length and TPTB between pregnant woman at 24-36 weeks of gestation.
Analysis of preterm delivery risk factors - a literature review
TLDR
Defining preterm delivery risk factors allows one to identify groups of preg-nant women who are at greater risk of premature birth and to apply appropriate preventive measures in time.
Obstetrician–Gynecologists’ Screening and Management of Preterm Birth
TLDR
Most obstetrician–gynecologists are practicing in accord with current findings on preterm birth risk factors and interventions, however, there may be overscreening and underscreening for various infections and overuse of bed rest as a pre term birth intervention.
A study of cervical length measured ultrasonographically in prediction of preterm delivery
TLDR
Measurement of cervical length by TVS can be used to predict increase risk of preterm delivery cases with threatened preterm labor, and was found to have good sensitivity, specificity, predictive value in both groups.

TLDR
The performance of the fetal fibronectin test was also too low to be clinically relevant, and the best use policy probably still depends on local contingencies, future cost-effectiveness analysis, and comparison with other more recent available biochemical markers.
Significance of Cervical Gland Area in Predicting Preterm Birth for Patients with Threatened Preterm Delivery: Comparison with Cervical Length and Fetal Fibronectin
TLDR
Predictive efficacy was analyzed in women at high risk for PTD and compared with cervical length <20 mm and fetal fibronectin in cervicovaginal secretions to identify positive fFN and short CL with absent CGA as independent predictors forPTD.
Epidemiology and causes of preterm birth
Prevention of Preterm Birth
TLDR
Reliable and accessible screening methods are necessary for antenatal care, and risk factors for PTB should be studied and clarified in search of useful tools to solve issues of risk pregnancies to decrease PTB rates and associated complications.
The Impact of Routine Transvaginal Ultrasound Measurement of the Cervical Length on the Prediction of Preterm Birth: A Retrospective Study in a Tertiary Hospital.
TLDR
The present study showed an inverse association between TUCL and PTB, and that the inclusion of other risk factors like maternal age, previous PTB and cervical surgery can improve the screening algorithm, and emphasizes that the T UCL cut-off that defines short cervix can differ according to the population.
Ultrasound Assessment of Fetal Adrenal Gland in Term and Preterm Labor Cases
TLDR
The growth in FZ as a fetal adaptation mechanism in increased fetal stress in preterm labor cases was at a significant level and it is thought that this result would be beneficial in the prediction of pre term labor in clinical practice.

Fetal fibronectin as a predictor of preterm birth: an overview.
TLDR
For symptomatic women, a negative test for fetal fibronectin should be useful at ruling out the likelihood of delivery within 7 to 10 days of sampling, as many women at risk will be misclassified as normal.
Preventing preterm birth: are we making any progress?
TLDR
Recent secular trends in preterm birth are reviewed and the evidence about possible reasons for those trends are reviewed, including ignorance about the causal determinants, increases in multiple births, and use of early ultrasound to estimate gestational age.

TLDR
Most industrialized countries have reported recent decreases in the size of infants born at term but no reduction, or even a rise in the incidence of preterm birth, and the evidence about possible reasons for those trends is reviewed.
Accuracy of cervicovaginal fetal fibronectin test in predicting risk of spontaneous preterm birth: systematic review
TLDR
Cervicovaginal fetal fibronectin test is most accurate in predicting spontaneous preterm birth within 7-10 days of testing among women with symptoms of threatened pre term birth before advanced cervical dilatation.
Prediction of prematurity.
TLDR
Combinations of older risk factors and newer, more sensitive diagnostic methods may greatly increase the ability to predict preterm birth and to identify women who might benefit most from directed intervention strategies.
The preterm prediction study: can low-risk women destined for spontaneous preterm birth be identified?
TLDR
In the setting of low-risk pregnancy, fetal fibronectin assay and cervical ultrasonography have low sensitivity for preterm birth before 35 weeks' gestation in women without clinical risk factors.
